CERTAIN  TECHNICAL TERMS AND ACRONYMS USED IN THIS PROSPECTUS ARE DEFINED IN THE

TELECOMMUNICATIONS  SERVICE  PROVIDERS  TO CONSIST  GENERALLY  OF  BOTH CARRIERS
OPERATING VOICE  AND DATA  NETWORKS FOR  THEIR CUSTOMERS  AND ENTERPRISES  WHICH
OPERATE VOICE AND DATA NETWORKS FOR THEIR OWN USE.
    
 
   
                                  THE COMPANY
    
 
    ACE*COMM  Corporation ("ACE*COMM"  or the  "Company") develops,  markets and
services operations support  systems ("OSS") products  for networks deployed  by
telecommunications  service providers, such as telephone companies, other public
carriers 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 for
some of the largest carriers and enterprises in the world.
 
   
    Increasing worldwide demand for data, voice and video services has created a
need for  increased network  capacity  and new  network services.  In  addition,
telecommunications   service   providers   face   an   increasingly  competitive
environment due  to  continued  deregulation and  privatization  of  the  global
telecommunications  industry. In  response to  these developments, interexchange
and local exchange carriers and  providers of Internet, personal  communications
and cellular services are offering a wide range of network features and options.
As  a result of the growth in  network usage and new services, large enterprises
require timely, accurate  information regarding network  performance and  system
usage  to support the increasing volumes of data and voice communications to and
from employees, customers  and suppliers.  ACE*COMM's products  are designed  to
enable  carriers and large enterprises  to optimize the use  of new and existing
communications networks.
    
 
    The  Company's  carrier  network   products  connect  to  existing   network
infrastructures  and  enable carriers  to  rapidly and  accurately  collect call
records and  performance  data which  are  used for  billing,  fraud  detection,
customer  care, marketing research and forecasting, and other operations support
functions. These  products are  designed to  enhance the  carriers'  competitive
position  by allowing them to offer  new features and services, minimize network
down-time, increase revenue through more accurate and timely billing and improve
network productivity.  The  Company  believes  that it  is  well  positioned  to
continue  to  offer  its  carrier network  products  to  international customers
located, for  example, in  Europe, Asia  and the  Pacific Rim,  which  typically
operate  a wide variety  of switches from different  manufacturers and require a
data collection system capable of adapting  to and integrating with the  billing
system and other OSSs.
 
    Leveraging  its  experience  in  developing  carrier  network  products, the
Company has  also produced  network management  products that  meet the  growing
needs of large enterprises in the United States and abroad, including government
agencies,  military organizations,  educational institutions  and "Fortune 1000"
size organizations. As these enterprises  have become increasingly dependent  on
the  Internet and intranets for voice  and data communications, their demand for
reliable and  flexible network  management tools  has increased.  The  Company's
network  management products consist of standardized software-based systems that
enable network managers to  manage voice and  data communications by  automating
service  administration, tracking  network connections,  detecting system errors
and malfunctions, controlling network  inventory assignments and  configuration,
monitoring
 
                                       3

traffic  and  performing  billing functions.  The  Company's  network management
products are designed to increase the efficiency of communication operations and
incorporate  recent  developments  in  object-oriented  development,   real-time
response, client server architecture and graphical user interfaces.
 
   
    The   Company  is  well  positioned  to  develop  products  to  support  the
convergence and growth of telephony and data networks within the enterprise,  as
a  result of its knowledge and experience  in data control and network switching
technology, data capture and warehousing, and client server systems. The Company
presently is  partnering with  Newbridge Networks  Corporation ("Newbridge")  to
develop  software designed to  provide billing data  collection capabilities for
asynchronous transfer  mode ("ATM"),  Frame  Relay and  X.25 switch  users.  The
Company   anticipates  similar  opportunities  to  develop  other  network  edge
technologies for equipment and service providers in the growing market for  data
services.
    
 
    The  Company has established  strategic alliances with  several companies in
order to distribute its  products effectively and develop  products that can  be
responsive  to the  needs of  the Company's  end users.  The Company's principal
strategic partners are  AT&T Corporation, Cincinnati  Bell Information  Systems,
Inc.  ("CBIS"),  Teleglobe Canada,  Inc. ("Teleglobe"),  International Computers
Limited ("ICL"), Lucent Technologies,  Inc., GTE Government Systems  Corporation
("GTE   Government   Systems")  and   BellSouth  Communication   Services,  Inc.
("BellSouth"). These  relationships have  resulted in  the sale  of products  to
domestic  and overseas carriers,  the U.S. Armed Forces,  the U.S. Department of
State and  major airports,  among  others. The  alliances have  been  especially
helpful in enabling the Company to further penetrate, on a cost-effective basis,
the  international  telecommunications  carrier  markets,  where  the  Company's
alliance  partners  are  well   recognized  and  have  well-developed   business
relationships.  The  Company  also sells  directly  to large  customers  such as
Telefonos de Mexico S.A. de C.V. ("TELMEX"), NYNEX and the University of Iowa.
 
   
    The Company's carrier network products have  been installed in over 500  end
user  sites  in  32 countries  and  its  network management  products  have been
installed in over 100 end user sites in 10 countries. The Company believes  that
these  installations constitute one of the  largest installed bases in the world
for billing mediation and network  management systems in the  telecommunications
service  provider market. The Company's carrier network products can be tailored

                                  RISK FACTORS
 
    AN  INVESTMENT IN THE COMMON STOCK OFFERED  HEREBY INVOLVES A HIGH DEGREE OF
RISK. THE  FOLLOWING  FACTORS  AND CAUTIONARY  STATEMENTS  SHOULD  BE  CAREFULLY
CONSIDERED IN EVALUATING THE COMPANY AND ITS BUSINESS.
 
   
    RELIANCE  ON  SIGNIFICANT CUSTOMERS  AND  LARGE ORDERS;  LONG  SALES CYCLES;
FLUCTUATIONS IN  RESULTS. A  significant portion  of the  Company's revenue  has
been,  and will continue to be, derived  from substantial orders placed by large
organizations. For  the year  ended June  30, 1996,  TELMEX and  Teleglobe,  its
largest   carrier  network   product  customers  for   the  period,  represented
approximately 28.8% and 10.5% of  total revenue, respectively, and ANSTEC,  Inc.
("ANSTEC")  and GTE Government  Systems, its largest  network management product
customers for  the period,  represented approximately  11.3% and  6.5% of  total
revenue,  respectively. 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. Furthermore, such customers are concentrated
in  the  carrier  market.  The  Company's future  success  may  depend  upon the
continued demand  by such  customers  for its  products and  services.  Customer
demand  can be affected by numerous variables, including 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 in this market, 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. There can be no assurance that revenue  from
customers  that  have  accounted  for  significant  revenues  in  past  periods,
individually or as a group, will continue, or if continued will reach or  exceed
historical  levels in any future period. 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.
    
 
    The  Company's revenue is difficult to forecast as a result of the fact that
the purchase  of operations  support and  network management  systems  generally
involves  a significant commitment of  capital and management time. Accordingly,
the sales cycle associated with the  purchase of the Company's products --  from
initial  contact to contract  execution and delivery of  product -- typically is
lengthy, varies from customer  to customer and from  project to project, and  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  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.
 
    As  a result of these  and other factors, the  Company believes that revenue
and operating results, and  particularly quarterly results,  are likely to  vary
significantly   in  the  future  and  to  be  difficult  to  forecast  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.
In  addition,  the  Company's  expense  levels  are  based,  in  part,  on   its
expectations   as  to  future  revenue  levels.  If  revenue  levels  are  below
expectations in any given period, operating results are likely to be  materially
adversely  affected.  Further,  it is  likely  that  in some  future  period the
Company's revenue or operating results will be below the expectations of  public
market analysts and investors. In such event, the price of the Common Stock will
be  materially adversely affected. See  "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Selected Quarterly Results" and
"Business -- Strategic Alliances and Other Customers."
 
   
    RELIANCE ON CARRIER MARKET.  The  Company derived a majority of its  revenue
from  sales to carriers during the years ended  June 30, 1995 and 1996. Sales to
the carrier  market are  expected to  provide the  substantial majority  of  the
Company's  revenue in the near future.  The Company's business is dependent upon
the  continued  growth  of  the   telecommunications  industry  in  the   United
    
 
                                       8
<PAGE>
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 and its results of operations.
 
    The  telecommunications industry is  subject to extensive  regulation in the
United States and  other countries  and regulatory approvals  generally must  be
obtained  by most of the Company's customers. The enactment by federal, state or
foreign governments of new laws or regulations or changes in the  interpretation
of existing regulations could adversely affect the Company's customers.
 
   
    Any  adverse development in  the carrier market,  including reregulation, or
reduction in demand for the Company's products by these industry sectors,  could
have  a  material  adverse effect  on  the  financial condition  and  results of
operations of the Company.
    
 
   
    RISKS ASSOCIATED WITH  INTERNATIONAL OPERATIONS.   Sales of  products to  be
delivered  outside of the United States accounted for approximately 62.9%, 68.6%
and 69.0% of the Company's total revenue for the years ended June 30, 1994, 1995
and 1996,  respectively. The  Company  expects that  revenue  from the  sale  of
products outside of the United States will continue to account for a significant
portion  of its total  revenue in future  periods. The Company  intends to enter
additional international  markets  and  to continue  to  expand  its  operations
outside  of  the United  States  by expanding  its  direct sales  force, opening
additional in-region customer  support and sales  offices, adding licensees  and
distributors  and pursuing additional strategic relationships. Market acceptance
of the Company's  products for emerging  markets, such as  Asia and the  Pacific
Rim, is important to the Company's future success, but these markets are diverse
and  rapidly  evolving, and  it is  difficult to  predict their  potential size,
future growth rate or  the timing of their  development. In addition, access  to
international  markets is often  difficult due to  the established relationships
between  a  government  owned  or  controlled  communications  company  and  its
traditional  indigenous suppliers of communications products. Accordingly, there
can be no assurance that the Company's  products will be widely accepted by  the
service  providers in these emerging markets or that the Company will be able to
continue to penetrate these markets effectively.
    
 
   
    The proposed  further  expansion  into international  markets  will  require
significant  management  attention  and  expenditure  of  significant  financial
resources and  could  adversely  affect the  Company's  operating  margins.  The
Company's  international  operations and  revenue involve  a number  of inherent
risks, including extensive field  testing and lengthier  sales cycles than  with
domestic customers, longer receivables collection periods and greater collection
difficulty,  difficulty in  staffing and managing  international operations, the
impact of possible  recessionary environments  in economies  outside the  United
States,  unexpected changes in regulatory  requirements, including a slowdown in
the rate  of  privatization of  carriers,  reduced protection  for  intellectual
property  rights in some  countries and tariffs and  other trade barriers. There
can be no assurance that the Company will be able to sustain or increase revenue
derived from international sales or that  the foregoing factors will not have  a
material  adverse  effect on  the Company's  future international  revenue, and,
consequently, on the Company's results of operations and financial condition.
    
 
    Currency exchange fluctuations in countries  in which the Company sells  its
products  could  have a  material  adverse effect  on  the Company's  results of
operations  and  financial  condition  by  resulting  in  pricing  that  is  not
competitive  with products  priced in  local currencies.  In addition,  sales in
Europe and certain other parts of the world typically are adversely affected  in
the  third quarter of each calendar year as many customers reduce their business
activities during the summer months. If the Company's international sales become
a greater component  of total revenue,  these seasonal factors  may have a  more
pronounced   effect  on  the  Company's  operating  results.  See  "Management's
Discussion and  Analysis  of Financial  Condition  and Results  of  Operations,"
"Business  --  Sales  and  Marketing"  and  "--  Strategic  Alliances  and Other
Customers."
 
                                       9
<PAGE>
   
    DEPENDENCE ON THIRD  PARTY RELATIONSHIPS.   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.  Many  of  the
Company's strategic alliances are nonexclusive and certain of the companies with
which  the  Company  has  such  alliances  also  have  agreements  with,  or are
themselves, competitors or  potential competitors  of the  Company. The  Company
believes  that these alliances  are critical to the  Company's ability to expand
its penetration of international markets for its carrier network products and to
increase sales of its  network management products in  the United States.  There
can  be no assurance that the  Company's strategic partners will not discontinue
one or more  of their alliances  with the Company  or form additional  competing
arrangements with competitors of the Company or themselves begin to compete with
the Company. See "Business -- Strategic Alliances and Other Customers."
    
 
   
    DEPENDENCE ON KEY PERSONNEL.  The Company's success depends to a significant
degree  upon the continuing contributions of its key management, sales, customer
support and product development personnel.  In particular, the Company would  be
materially adversely affected if it were to lose the services of George Jimenez,
Joseph Dorr or Dr. Thomas Russotto, who have provided significant leadership and
direction  to the Company since its inception and who have significant knowledge
of the Company's proprietary technology and products. The Company currently does
not have employment agreements with its key personnel, although the Company  has
non-competition and non-disclosure agreements with each of them. The Company has
obtained key man life insurance on the life of Mr. Jimenez in the amount of $1.0
million,  payable  to  the Company.  The  loss  of key  management  or technical
personnel could  have a  material adverse  effect on  the Company's  results  of
operations and financial condition.
    
 
    INTENSE  COMPETITION.  The market for carrier network and network management
products is highly competitive. Many providers offer products that are  directly
competitive with those offered by the Company in both domestic and international
markets.   The  Company  also  experiences  competition  from  in-house  systems
developed by existing and potential customers. Many of the Company's current and
potential  competitors   have   significantly  greater   financial,   marketing,
technical,  and  other  competitive  resources  than  the  Company.  Current and
potential competitors, including providers  of software or processing  services,
may  establish cooperative relationships with one  another or with third parties
or consolidate  to compete  more effectively  against the  Company. It  is  also
possible  that new competitors may emerge and acquire market share. Any of these
events could  have  a  material  adverse effect  on  the  Company's  results  of
operations and financial condition. See "Business -- Competition."
 
    NEW PRODUCTS AND TECHNOLOGY AND NEED TO RESPOND TO RAPIDLY CHANGING CUSTOMER
NEEDS.   The market for the Company's  products is characterized by rapid change
and is highly competitive with respect to the need for timely product innovation
and new  product introductions.  The Company  believes that  its future  success
depends  in part upon its  ability to enhance its  current offerings and develop
new products  that  address the  increasingly  complex needs  of  customers.  In
particular,  the Company  believes that  it must  respond quickly  to customers'
needs for additional functionality and  new software technologies. There can  be
no  assurance that the  Company will be  able to do  so. The Company continually
seeks to develop new products and individual features within a complex  hardware
and  software system.  Development projects  can be  lengthy and  are subject to
changing requirements, programming  difficulties, and  unforeseen factors  which
can result in delays. In addition, new products or features, when first released
by  the  Company, may  contain undetected  errors that,  despite testing  by the
Company, are discovered  only after  a product has  been installed  and used  by
customers.  Delays or undetected errors could  have a material adverse effect on
the Company's results of operations and financial condition.
 
                                       10
<PAGE>
    The introduction  or announcement  by the  Company  or one  or more  of  its
competitors  of  products embodying  new  technologies, or  changes  in industry
standards or customer requirements, could render the Company's existing products
obsolete or unmarketable. The  introduction of new or  enhanced versions of  its
products  also requires the Company to manage the transition from older products
in order  to  minimize  disruption  in customer  operations.  There  can  be  no
assurance that the introduction or announcement by the Company or one or more of
its  competitors of new  products, or changes in  industry standards or customer
requirements, will not cause  customers to limit or  defer purchases of  Company
products.  Such actions  could have a  material adverse effect  on the Company's
results of operations and financial condition.
 
    MANAGEMENT OF GROWTH.  The Company is expanding into new products,  services
and  markets. This growth has resulted in new and increased responsibilities for
management personnel and has placed and continues to place a significant  strain
upon  the Company's management,  operating and financial  systems and resources.
Although the  Company believes  that there  are currently  no existing  material
weaknesses, in order to accommodate recent growth and to compete effectively and
manage  future  growth, if  any, the  Company  will be  required to  continue to
implement and improve operating,  financial and management information  systems,
procedures  and controls on a timely basis and  in such a manner as is necessary
to accommodate  the  increased number  of  transactions and  customers  and  the
increased size of the Company's operations. Management of future growth, if any,
will  also require  that the  Company continuously  expand, train,  motivate and
manage its work force. These demands will require the addition of new management
personnel. The Company's future success will  depend to a significant extent  on
the ability of its current and future executive officers to operate effectively,
both  independently and as a group. There can be no assurance that the Company's
personnel, systems,  procedures and  controls will  be adequate  to support  the
Company's  existing and future operations. Any  failure to implement and improve
the Company's operating, financial and  management systems or to expand,  train,
motivate  or  manage  employees could  have  a  material adverse  effect  on the
Company's results of operations and financial condition.
 
   
    DIFFICULTY IN ATTRACTING AND RETAINING NECESSARY PERSONNEL.  Certain members
of the senior management team of the Company have been in place for a relatively
short time.  Jeffrey Simpson,  Vice President,  Finance, and  James Moore,  Vice
President,  Marketing,  began  their  employment  in  July  1996  and  May 1996,
respectively. The Company believes that its future success will depend in  large
part  upon  its  ability  to  continue  to  attract  and  retain  highly skilled
managerial,  sales,  professional   services,  customer   support  and   product
development  personnel. The  Company has at  times experienced  and continues to
experience  difficulty  in  recruiting  qualified  personnel.  Competition   for
qualified  personnel  with  knowledge  of  the  telecommunications  industry  is
intense, and there can be  no assurance that the  Company will be successful  in
attracting  and retaining  such personnel.  The complex  nature of  the products
demanded by the Company's customers requires  that the Company recruit and  hire
personnel  with expertise in and a broad understanding of the telecommunications
and other  industries in  which the  Company's customers  compete. In  addition,
there  are only a  limited number of qualified  development and customer support
engineers,  and  competition  for   such  individuals  is  especially   intense.
Competitors  have  in the  past and  may in  the future  attempt to  recruit the
Company's employees. Failure to  attract and retain key  personnel could have  a
material  adverse effect  on the Company's  results of  operations and financial
condition.
    
 
    DEPENDENCE UPON PROPRIETARY TECHNOLOGY.   The Company's success and  ability
to  compete is  dependent in part  upon its proprietary  technology. The Company
relies  on  a  combination  of  trade  secret,  copyright  and  trademark  laws,
nondisclosure and other contractual agreements and technical measures to protect
its  proprietary  rights.  The  Company  currently  has  no  patents  or  patent
applications pending. Despite the Company's  efforts to protect its  proprietary
rights,  unauthorized  parties  may attempt  to  copy aspects  of  the Company's
products  or  to  obtain  and  use  information  that  the  Company  regards  as
proprietary,  or to develop  products with functionality  or features similar to
the Company's  products that  are substantially  equivalent or  superior to  the
Company's products. In addition, effective copyright, trademark and trade secret
protection may be unavailable or limited in
 
                                       11
<PAGE>
certain  countries. The Company believes that its products and trademarks do not
infringe upon  the proprietary  rights of  third parties,  but there  can be  no
assurance   that  third  parties  will  not  in  the  future  assert  claims  of
infringement of  their proprietary  rights.  Any such  claims, with  or  without
merit,  could  be time-consuming,  result  in costly  litigation,  cause product
shipment delays or require the  Company to develop non-infringing technology  or
enter  into royalty or licensing  agreements which, if available,  may not be on
terms acceptable to  the Company. A  claim of product  infringement against  the
Company  and  failure  or inability  of  the Company  to  develop non-infringing
technology, or  license  the  infringed  or similar  technology,  could  have  a
material  adverse effect  on the Company's  results of  operations and financial
condition. The Company relies  on certain software that  it licenses from  third
parties,  including  software  that  is  integrated  with  internally  developed
software and used in the Company's products to perform key functions. There  can
be  no assurance that  these third party  software licenses will  continue to be
available to the Company on commercially  reasonable terms. The absence of  such
software,  if the Company is unable to  find a substitute, could have a material
adverse effect on the  Company's ability to produce  products. See "Business  --
Proprietary Rights and Licenses."
 
   
    NO PRIOR PUBLIC MARKET; DETERMINATION OF OFFERING PRICE; POSSIBLE VOLATILITY
OF STOCK PRICE.  Prior to this offering, there has been no public market for the
Common  Stock. There  can be  no assurance  that an  active trading  market will
develop for the Common Stock or that  the price at which shares of Common  Stock
may  trade in the  public market from  time to time  subsequent to this offering
will exceed the initial public offering price. The initial public offering price
will be determined by negotiations  between the Company and the  representatives
of  the Underwriters  and may  not be  indicative of  future market  prices. See
"Underwriting" for a discussion of factors  to be considered in determining  the
initial  public  offering  price.  The  stock  market  has  from  time  to  time
experienced  extreme  price  and   volume  fluctuations,  particularly  in   the
technology  sector, which often have been unrelated to the operating performance
of particular  companies.  Any announcement  with  respect to  any  variance  in
revenue  or earnings from levels generally expected by securities analysts for a
given period could have an immediate and significant effect on the trading price
of the Common Stock. In addition, factors such as announcements of technological
innovations or new products by the  Company, its competitors, or third  parties,
as  well as changing market  conditions in the industry,  may have a significant
impact on the market price of the Common Stock.
    
 
   
    SHARES ELIGIBLE FOR FUTURE SALE.  Sales of a substantial number of shares of
Common Stock in the public market following this offering could adversely affect
prevailing market prices for the Common Stock. Upon the expiration of  "lock-up"
agreements,  180  days  following  the date  of  this  Prospectus, approximately
4,748,211 shares of Common  Stock will be  eligible for sale  under Rule 701  or
Rule  144 under the Securities  Act of 1933, as  amended (the "Securities Act"),
except to the extent  owned by affiliates  of the Company. On  the date 90  days
following the date of this Prospectus and without consideration of the foregoing
contractual  restrictions,  substantially all  of  the Common  Stock outstanding
prior to this offering would be eligible for sale in the public markets  subject
to  the provisions of Rule 144. After this offering, holders of 1,300,950 shares
of Common Stock are entitled to certain registration rights (taking into account
the conversion of the Class C  Preferred Stock). If such holders, by  exercising
their  registration rights, cause a large number  of shares to be registered and
sold in the public market, such sales  may have an adverse effect on the  market
price  for the Common Stock. In addition, the Company intends to register on one
or more registration statements filed after  completion of this offering, up  to
2,400,000 shares of Common Stock reserved for issuance under the Company's stock
plans. Shares covered by these registration statements will be eligible for sale
in  the public market immediately after the effective dates of such registration
statements. Sales of  substantial shares of  Common Stock in  the public  market
following  this offering, or  the perception that such  sales could occur, could
adversely affect the market  price of the Common  Stock prevailing from time  to
time  and could impair the Company's future  ability to raise capital through an
offering of its  equity securities. See  "Shares Eligible for  Future Sale"  and
"Underwriting."

<PAGE>
   
    CONTROL  BY EXISTING STOCKHOLDERS; ANTI-TAKEOVER  PROVISIONS.  The Company's
directors and  officers  and  their  affiliates will,  in  the  aggregate,  own,
directly  or indirectly, more  than 53.0% of the  outstanding Common Stock after
this offering, assuming no exercise of  outstanding options. As a result,  these
stockholders,  if  they act  together,  would be  able  to control  most matters
requiring approval  by the  Company's stockholders,  including the  election  of
directors.  See "Principal  and Selling  Stockholders" and  "Shares Eligible for
Future Sale."  In  addition, the  Company's  Charter and  By-laws  will  contain
provisions  that  may discourage  acquisition bids  for  the Company  by persons
unrelated to certain existing stockholders.  The effect of this stock  ownership
and  these provisions may be to limit  the price that investors might be willing
to pay in  the future  for shares  of the  Common Stock  or prevent  or delay  a
merger,  takeover, or other change in control of the Company and thus discourage
attempts to acquire the Company. In  addition, the Company's Board of  Directors
has  the authority  to issue up  to 5,000,000  shares of Preferred  Stock and to
determine the price, rights, preferences and privileges of those shares  without
any  further vote or  action by the  stockholders. The rights  of the holders of
Common Stock will be subject to, and may be adversely affected by, the rights of
the holders  of any  Preferred  Stock that  may be  issued  in the  future.  The
issuance  of  Preferred Stock,  while providing  flexibility in  connection with
possible acquisitions and  other corporate  purposes, could have  the effect  of
making  it  more  difficult for  a  third party  to  acquire a  majority  of the
outstanding voting stock  of the  Company. The Company  has no  present plan  to
issue  any shares of Preferred Stock.  The Company's Charter and By-laws contain
other provisions, such as notice requirements for stockholders, staggered  terms
for  its Board  of Directors,  and limitations  on the  stockholders' ability to
remove directors or to present proposals to the stockholders for a vote, all  of
which  may have the further effect of making it more difficult for a third party
to gain control or  to acquire the Company.  See "Description of Capital  Stock"
and "Certain Charter and By-Law Provisions."
    
 
   
    DILUTION.   The initial  public offering price  will be substantially higher
than the  book value  per share  of  Common Stock.  Assuming an  initial  public
offering  price of $10.00 per share (the mid-point of the estimated range of the
initial public offering  price), investors participating  in this offering  will
incur  immediate, substantial dilution of approximately  $7.02 per share. To the
extent outstanding options to purchase Common Stock are exercised, there will be
further dilution. See "Dilution."

<PAGE>
                                USE OF PROCEEDS
 
   
    The net proceeds to  the Company from  the sale of  the 2,270,000 shares  of
Common  Stock offered  by the Company  hereby are estimated  to be approximately
$20.2 million (approximately $24.0  million if the Underwriters'  over-allotment
option  is exercised  in full), after  deducting the  underwriting discounts and
commissions and estimated offering expenses and assuming a public offering price
of $10.00 per share.
    
 
   
    The Company expects to use the  net proceeds for general corporate  purposes
including working capital and employment of additional personnel, provided that:
(i)  certain amounts will  be used for  repayment of bank  indebtedness of which
approximately $5.0 million was outstanding at June 30, 1996, (ii)  approximately
$0.4  million will be used  for redemption of all  outstanding shares of Class B
Preferred Stock and the repayment of certain indebtedness held by the holder  of
such shares, of which approximately $52,000 was outstanding at June 30, 1996 and
(iii)  approximately  $0.1 million  will be  used  for repayment  of outstanding
related-party indebtedness.  See  Notes  5  and 6  to  the  Company's  financial
statements and "Certain Transactions" for further information.
    
 
    The principal purposes of this offering are to increase the Company's equity
and  to  create a  public market  for  the Company's  Common Stock.  The Company
believes that success in its industry  requires substantial capital in order  to
maintain the flexibility to take advantage of opportunities that arise and to be
able  to withstand adverse  business conditions, should  they occur. Portions of
net proceeds may also be used to fund acquisitions of complementary  businesses,
products or technologies, although no specific acquisitions are planned or under
negotiation  as of the date of this  Prospectus. The Company has not allocated a
significant portion of the net proceeds of this offering to any particular  use.
Accordingly,  management will have  significant flexibility in  applying the net
proceeds of  this offering.  Pending application  of the  proceeds as  described
above,  the  Company intends  to invest  the  net proceeds  in investment-grade,
short-term securities.
 
    The Company will not receive any of the proceeds from the sale of shares  of
Common   Stock  by   the  Selling   Stockholder.  See   "Principal  and  Selling
Stockholders."
 
                                DIVIDEND POLICY
 
    The Company has never declared or  paid cash dividends on the Common  Stock.
The  Company currently intends to retain earnings, if any, to finance the growth
and development of its business and does not anticipate paying cash dividends in
the foreseeable  future.  The terms  of  the Company's  bank  credit  facilities
prohibit  the  payment  of  cash  dividends.  See  "Management's  Discussion and
Analysis of  Financial Condition  and  Results of  Operations --  Liquidity  and
Capital Resources." The future payment of cash dividends, if any, is also within
the discretion of the Board of Directors and will depend on the future earnings,
capital  requirements, financial condition  and future prospects  of the Company
and such other factors as the Board of Directors may deem relevant.

    The following table sets forth the capitalization of the Company as of  June
30,  1996, (i) on an actual basis giving  effect to a 4.5-to-one stock split and
(ii) as adjusted  to give  effect to  (a) the  issuance of  1,530,950 shares  of
Common  Stock upon the conversion of all outstanding shares of Class C Preferred
Stock and  (b) the  sale of  2,270,000 shares  of Common  Stock offered  by  the
Company  hereby (at an assumed initial public  offering price of $10 per share),
and the application of the estimated net proceeds of this offering as  described
in  "Use  of  Proceeds." This  table  should  be read  in  conjunction  with the
Company's financial  statements and  notes thereto  included elsewhere  in  this
Prospectus.

                                    DILUTION
 
   
    The pro forma net tangible book value of the Company as of June 30, 1996 was
$2.1  million, or $.41 per  share of Common Stock.  "Pro forma net tangible book
value" per  share represents  the amount  of total  tangible assets  less  total
liabilities,  divided  by  the  total  number of  shares  of  Common  Stock then
outstanding (without giving effect to  this offering but assuming the  automatic
conversion  of all outstanding shares of  Class C Preferred Stock into 1,530,950
shares of Common Stock and the effectiveness of a 4.5-to-one stock split).
    
 
   
    After giving effect to the  sale by the Company  of the 2,270,000 shares  of
Common  Stock offered by  the Company and  the application of  the estimated net
proceeds of this offering as described in "Use of Proceeds" (after deduction  of
underwriting  discounts and  commissions and  estimated offering  expenses), the
Company's pro forma net tangible  book value at June  30, 1996, would have  been
$22.0  million, or $2.98 per share of Common Stock to purchasers of Common Stock
in this offering. This  represents an immediate dilution  of $7.02 per share  to
new investors. The following table illustrates the per share dilution:

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    The  Company sells carrier network products and network management products,
both through direct channels  and through its  strategic alliance partners,  for
delivery in the United States and internationally. Since June 1994, the Company,
consistent with its strategic emphasis, has derived most of its revenue from the
sale  of its  carrier network  products. The Company  expects the  sales of such
products to  increase as  a percentage  of its  revenue for  at least  the  next
several  years. The balance of the Company's revenue is derived from the sale of
network management products to enterprise  customers, including agencies of  the
U.S. Government.
 
   
    The  Company has generated growth in its  revenue in every fiscal year since
fiscal 1986 except  for fiscal  1995. In  fiscal 1995,  the Company  experienced
simultaneous  delays in  three large  contract awards  due to  internal customer
matters unrelated to  the Company and  beyond its control.  The delays caused  a
decline  in the Company's revenue, without  any offsetting reduction in expenses
because of the need to retain  key personnel, maintain fixed overhead costs  and
incur  substantial sales and marketing expenses associated with trying to obtain
the delayed contracts. Two of these delayed contracts, one awarded by NYNEX  and
one  by ANSTEC,  were finally awarded  late in  fiscal 1995 and  early in fiscal
1996, with the Company realizing revenue from these contracts in fiscal 1996.
    
 
   
    The Company's products  typically are sold  pursuant to long-term  contracts
having  an  aggregate  contract value  of  several hundred  thousand  to several
million dollars. As part of the contract, the Company agrees to provide  certain
services,  including postcontract  customer support, assistance  to customers in
the development and installation of new systems, maintenance and enhancement  of
installed  systems, and customer training and technical support. These contracts
may involve significant  production, modification or  tailoring of hardware  and
software.  The  Company recognizes  revenue principally  from contracts  of this
type, using the percentage-of-completion method, based on performance milestones
specified in  each  contract,  which fairly  reflect  progress  toward  contract
completion.  Revenue from maintenance and other postcontract customer support is
recognized ratably over the term of the related agreement.
    
 
    The Company sells  most of  its products as  components in  the products  or
systems developed and marketed by its strategic partners. The Company also sells
products 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 tracks two types  of backlog: "order backlog," which  represents
signed  purchase orders, and "contract backlog," which represents signed project
contracts that  become  order backlog  upon  the signing  of  specific  purchase
orders.  Order backlog reached its highest level in the Company's history during
fiscal 1996 and was $10.4 million at June 30, 1996, compared to $3.6 million  at
June 30, 1995.
    
 
   
    The Company's revenue typically is concentrated among certain customers, the
largest of which in fiscal 1996 consisted of TELMEX, ANSTEC and Teleglobe. These
customers  represented approximately  28.8%, 11.3%  and 10.5%,  respectively, of
total revenue for the year ended June 30, 1996. See "Risk Factors -- Reliance on
Significant Customers  and  Large Orders;  Long  Sales Cycles;  Fluctuations  in
Results" and "Business -- Backlog."
    
 
    As  a result of the size of most of its contracts, the significant length of
sales cycles and the  complexities which arise from  time to time in  completing
any  given contract, 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. The Company has experienced
significant delays in timing
 
                                       18

of revenue related  to sales  in overseas  markets. See  "-- Selected  Quarterly
Results."  See also "Risk Factors -- Reliance on Significant Customers and Large
Orders; Long Sales  Cycles; Fluctuations  in Results" and  "-- Risks  Associated
with International Operations."
    
 
    The  Company's cost of products and services consists of the cost of product
engineering and  production,  personnel  cost  of  customer  support  personnel,
license  fees paid  to third-party  software vendors,  amortization of  costs of
capitalized software  development and  the  cost of  hardware purchased  by  the
Company for incorporation into its 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, commissions,  rent, insurance,  depreciation and  non-product
amortization  expenses. 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  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.

</TABLE>
    
 
   
YEARS ENDED JUNE 30, 1995 AND 1996
    
 
   
    REVENUE.  Revenue  increased 61.3%,  from $12.4  million in  fiscal 1995  to
$20.0  million in fiscal  1996. The increase is  attributable to increased sales
volume of the  Company's carrier network  products to Teleglobe  and TELMEX  and
delivery of NetPlus-Registered Trademark- network management systems to the U.S.
Government pursuant to the Company's contract with ANSTEC.
    
 
   
    COST  OF PRODUCTS  AND SERVICES.   Cost  of products  and services increased
56.1% from $6.6  million in fiscal  1995 to  $10.3 million in  fiscal 1996.  The
increase   is  attributable  to  increased  purchases  of  hardware  related  to
DCMS-Registered Trademark- units for the TELMEX contract which were subsequently
incorporated in shipped products. Gross margins were 47.0% and 48.5% for  fiscal
1995  and  1996,  respectively.  The  improvement  in  gross  margin  was caused
primarily by efficiencies resulting from increased order quantities and the sale
of products directly to end users which have higher associated profit margins.
    
 
   
    SELLING, GENERAL AND  ADMINISTRATIVE.  Selling,  general and  administrative
expenses  increased 20.5% from  $6.0 million in  fiscal 1995 to  $7.3 million in
fiscal 1996. These  expenses represented  48.7% and  36.5% of  total revenue  in
fiscal  1995 and  fiscal 1996, respectively.  The increase in  these expenses is
attributed to the  selling cost associated  with the TELMEX  contract and  costs
associated  with the  Company's continued  expansion of  marketing programs. The
Company expects these expenses to increase in future periods as a result of  its
continued work on the TELMEX contract, its efforts to
    
 
                                       19
<PAGE>
   
position itself to penetrate international markets for carrier network products,
its  plans to expand sales  of network management products  in the United States
and the hiring of  additional management personnel. See  "Business -- Sales  and
Marketing."
    
 
   
    RESEARCH  AND DEVELOPMENT.  Research  and development expense decreased 8.4%
from fiscal 1995 to fiscal 1996, primarily as a result of completion of work  on
software  development  related  to  the technology  platform  for  the Teleglobe
contract. As a percentage of revenue, research and development expense decreased
from 8.4% in fiscal  1995 to 4.8% in  fiscal 1996 primarily as  a result of  the
increase  in period to  period revenues. The Company  plans to spend significant
resources on research and development in future periods in order to enhance  its
technology  and expects  that expenses, as  a percentage of  total revenue, will
increase.
    
 
   
    PROVISION FOR INCOME TAXES.  No income tax benefit or provision was recorded
for the  fiscal years  ended June  30, 1995  and 1996,  respectively, since  any
benefit  or  provision was  offset  by a  similar  increase or  decrease  in the
valuation allowance.
    
 
YEARS ENDED JUNE 30, 1994 AND 1995
 
    REVENUE.  Revenue  decreased 14.5%,  from $14.5  million in  fiscal 1994  to
$12.4  million  in fiscal  1995. The  decrease  is attributable  to simultaneous
delays in three large contracts due to matters beyond the Company's control. See
"-- Overview."
 
   
    COST OF PRODUCTS  AND SERVICES.   Cost  of products  and services  decreased
14.3%  from $7.7  million in  fiscal 1994  to $6.6  million in  fiscal 1995. The
decrease is attributable to reduced  hardware purchases, reflecting the  reduced
delivery  of network management  products in fiscal 1995.  Since the decrease in
these costs was offset by a corresponding decrease in period to period  revenue,
cost  as a percentage of revenue remained unchanged. As a result, gross margins,
as a percentage of revenue were also unchanged.
    
 
   
    SELLING, GENERAL AND  ADMINISTRATIVE.  Selling,  general and  administrative
expenses  increased 10.5% from  $5.5 million in  fiscal 1994 to  $6.0 million in
fiscal 1995. These  expenses represented 37.7%  and 48.7% of  revenue in  fiscal
1994  and  fiscal 1995,  respectively. The  increase  in expenses  resulted from
increases in  the  Company's  direct  sales force  and  in  marketing  programs,
specifically  on  bid and  proposal efforts  relating to  the TELMEX  and ANSTEC
contracts described under "Business -- Strategic Alliances and Other Customers."
Additional costs were  incurred in  fiscal 1995  as a  result of  the hiring  of
executive  accounting personnel. The increase in  these expenses as a percentage
of revenue from  fiscal 1994  to fiscal 1995  is primarily  attributable to  the
decrease in period to period revenue.
    
 
   
    RESEARCH  AND DEVELOPMENT.   Research and development  expenses increased by
82.4% from $0.6 million  in fiscal 1994  to $1.0 million  in fiscal 1995.  These
expenses  represented  4.0%  and  8.4%  of  revenue  in  fiscal  1994  and 1995,
respectively. The increase in these expenses was primarily attributable to  work
performed  on  the  software  development relating  to  the  technology platform
developed in anticipation of a contract  with Teleglobe. An increase in  expense
was  also experienced  as a result  of hiring additional  software engineers and
support personnel in anticipation of planned research and development  expansion
in  fiscal 1996. The increase in these expenses as a percentage of total revenue
from fiscal 1994  to fiscal 1995  is primarily attributable  to the decrease  in
period to period revenue.
    
 
    PROVISION FOR INCOME TAXES.  No income tax benefit or provision was recorded
for the fiscal years ended June 30, 1994 and 1995 since any benefit or provision
was offset by a similar increase or decrease in the valuation allowance.

    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  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. The  failure to obtain  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  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.
 
                                       21
<PAGE>
    The Company's sales cycle,  from initial contact  to contract execution  and
delivery  of product,  also varies substantially  from customer  to customer and
from project to project.  The purchase of carrier  network products and  network
management  products  generally involves  a  significant commitment  of customer
capital and management time. The sales cycle associated with the purchase 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  Company's expense levels are based, in  part, on its expectations as to
future revenue  levels.  If revenue  levels  are below  expectations,  operating
results are likely to 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  expectations of public market analysts and
investors. In such  event, the  price of the  Common Stock  could be  materially
adversely affected.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
    Cash  used  in operating  activities was  $1,000  for 1994,  reflecting $1.2
million of income before depreciation  and amortization, offset by $1.2  million
of  changes  in  operating  assets  and  liabilities.  Cash  used  in  operating
activities was $1.2 million for 1995,  reflecting a loss of $0.9 million  before
depreciation and amortization, increased by $0.2 million of changes in operating
assets  and liabilities. Cash provided by  operating activities in 1996 was $0.7
million, reflecting $1.9 million of income before depreciation and amortization,
offset by a $1.2 million change in operating assets and liabilities.
    
 
   
    Cash used for investing activities of  $0.2 million, $1.0 million, and  $1.3
million  in  fiscal  1994, 1995  and  1996, respectively,  reflect  purchases of
property and equipment,  capitalization of  software development  costs and  the
sale  of short-term investments. Purchases of property and equipment, consisting
primarily of computers and  related equipment, were  $0.3 million, $0.5  million
and  $0.4  million  in fiscal  1994,  1995 and  1996,  respectively. Capitalized
software development costs were $0.7 million,  $0.5 million and $0.9 million  in
fiscal  1994, 1995  and 1996, respectively.  Sale of  short-term investments was
$0.8 million in fiscal 1994.
    
 
   
    To date, the Company has used sales of preferred equity, cash generated from
operations and revolving bank  lines of credit to  fund its working capital  and
investing activities. Effective March 1, 1996, the Company entered into a credit
agreement  with a bank to finance inventory  for a large foreign contract. Under
the agreement, the Company can borrow up to $1 million at 1.25% over the  bank's
prime  rate. The agreement requires the Company to comply with certain financial
covenants. The  U.S.  Export-Import  Bank  guarantees  90%  of  the  outstanding
balance,  which is collateralized  by the inventory  and the foreign receivables
generated by the contract. This agreement expires on August 31, 1996.
    
 
   
    The Company has a $2.5 million line of credit which expires on November  30,
1997. Borrowings under the facility bear interest, payable monthly, at 0.5% over
the  bank's prime  rate. The  Company also  has a  $1 million  revolving line of
credit. This facility bears interest, payable  monthly, at 0.5% over the  bank's
prime  rate  and is  due  on November  30, 1997.  In  addition, the  Company has
outstanding installment notes due in  varying monthly installments through  June
2000,  bearing interest  at 1.0%  over the  bank's prime  rate in  the aggregate
principal amount as of June 30, 1996 of approximately $0.6 million. These credit
arrangements are secured by accounts receivable, equipment and inventory certain
of which are subordinated to the  security interests under the credit  agreement
described in the immediately preceding paragraph, and these arrangements contain
certain  financial covenants. In addition, on June 21, 1996, the Company entered
into a loan agreement for $750,000, bearing interest at a rate of 0.5% over  the
bank's  prime rate, payable  monthly. The principal  is due on  August 20, 1996.
This agreement  also  requires the  Company  to comply  with  certain  financial
covenants.

<PAGE>
    The Company believes that the net proceeds from this offering, together with
existing cash balances, cash flow from operations and available bank lines, will
be  sufficient to support the Company's working capital requirement for at least
the  next  12  months.  Thereafter,   if  cash  generated  from  operations   is
insufficient  to satisfy the Company's working capital requirements, the Company
may be  required to  raise additional  funds.  No assurance  can be  given  that
additional  financing will  be available or  that, if  available, such financing
will be obtainable on terms favorable to the Company or its stockholders. To the
extent the Company raises  additional capital by  issuing equity or  convertible
debt  securities, ownership dilution to  the Company's stockholders will result.
In the event that adequate funds  are not available, the Company's business  may
be adversely affected.

                                    BUSINESS
 
GENERAL
 
   
    ACE*COMM  develops, markets and services  OSS products for networks deployed
by telecommunications  service providers,  such  as telephone  companies,  other
public  carriers 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 for some of the largest carriers and enterprises in the world.
    
 
    CARRIER NETWORK PRODUCTS
 
   
    The Company's carrier network products  include billing data collection  and
network  surveillance systems for carriers seeking the ability to bring services
to market  quickly and  for many  emerging carriers  that lack  state-of-the-art
billing  data collection systems. These  carriers typically focus their internal
development resources on  networking and switching  technology and on  marketing
their  services and turn to outside  suppliers to obtain OSSs. Outside suppliers
provide flexible, efficient solutions  that may be more  costly for carriers  to
develop internally.
    
 
    The  Company's  carrier  network  products, which  consist  of  software and
hardware, connect to  existing network  infrastructures and  enable carriers  to
rapidly  and accurately collect  call records and  performance data and generate
displays, graphics  and reports  which are  used for  billing, fraud  detection,
customer  care, marketing research and  forecasting and other operations support
functions. These  products are  designed to  enhance the  carriers'  competitive
position  by allowing them to offer  new features and services, minimize network
down-time, increase revenue through more accurate and timely billing and improve
network productivity.  The  Company  has  expertise derived  from  13  years  of
developing  products  adapted  to a  variety  of network  hardware  and software
configurations. The Company believes that  it is well-positioned to continue  to
offer  its  carrier network  products  to international  customers  located, for
example in Europe,  Asia and  the Pacific Rim,  which typically  operate a  wide
variety  of switches from different manufacturers  and require a data collection
system capable of adapting to and integrating with the billing system and  other
OSSs. The Company's carrier network products have been installed in over 500 end
user  sites in  32 countries  in North, South  and Central  America, Europe, the
Middle East, and Asia, including China.
 
    The Company expects to increase  revenues from international markets,  which
are   experiencing   increasing  deregulation   and  privatization,   and  where
telecommunications  infrastructures  have  not  reached  nearly  the  stage   of
development  as in  the United States.  The Company believes  that its strategic
alliances  with  prominent  U.S.   and  international  carriers  and   equipment
manufacturers,  such as  AT&T, ICL  and Teleglobe  which are  actively marketing
carrier systems abroad, will enable  it to effectively increase its  penetration
of international markets.
 
   
    The Company also expects demand for its carrier network products to increase
in   the  United  States  as  a  result  of  the  recent  passage  of  the  U.S.
Telecommunications Act of 1996, which removed certain existing barriers to entry
and is expected to result  in the creation of  new, alternative carriers and  to
cause existing carriers to upgrade their systems to meet increasing competition.
    
 
    NETWORK MANAGEMENT PRODUCTS
 
    The  Company's network management products are  designed to meet the growing
needs of large enterprises in the United States and abroad, including government
agencies, military organizations,  educational institutions  and "Fortune  1000"
size  organizations. As these enterprises  have become increasingly dependent on
the Internet and intranets for voice  and data communications, their demand  for
reliable and flexible network management tools has increased.
 
    The  Company  has packaged  network  management products  into standardized,
flexible state-of-the-art software based systems that enable network managers to
manage voice  and  data  communications by  automating  service  administration,
tracking network connections, detecting system errors
 
                                       24
<PAGE>
   
and   malfunctions,   controlling   the   network   inventory   assignments  and
configuration,  monitoring  traffic  and   performing  billing  functions.   The
Company's  network management products  have been installed  in networks in over
100 end users sites in 10 countries.
    
 
   
    The Company believes it  is well positioned to  develop products to  support
the convergence and growth of telephony and data networks within the enterprise,
as  a  result  of its  knowledge  and  experience in  data  control  and network
switching technology. The Company's network management products are designed  to
increase  the  efficiency  of communication  operations  and  incorporate recent
developments in object-oriented development,  real-time response, client  server
architecture and graphical user interfaces.
    
 
INDUSTRY BACKGROUND
 
    CARRIERS
 
   
    Historically,  the  telecommunications  industry has  been  characterized by
significant government regulation or ownership and limited competition. In  this
environment,  telecommunications services consisted  primarily of monopoly local
and long distance telephone service over traditional landlines. The beginning of
the break-up  of AT&T  in 1984  began a  deregulatory trend  that has  led to  a
proliferation of competition in the long-distance carrier market. More recently,
the  passage of the U.S. Telecommunications Act of 1996 is expected to create an
environment where both long distance and  local exchange carriers in the  United
States  will  increasingly compete  with  one another  for  both local  and long
distance services. In  addition, domestic  service providers  are aligning  with
international  telephone companies to deliver seamless services globally. Today,
both domestic and international  telephony carriers face increasing  competition
from  cable and wireless companies for  telephony and new, high bandwidth voice,
data and video services.
    
 
   
    In response to this evolving  competitive environment, carriers have  sought
to  reduce expenses and differentiate  themselves by improving existing services
and   rapidly   introducing   new    services   and   new   technologies.    New
telecommunications    services   include   high-speed   data   services,   video
teleconferencing, video-on-demand, home shopping  and home banking.  Competition
has increased the importance of rapidly bringing these new and enhanced services
to  market. The availability of new and  enhanced services has fueled a dramatic
increase  in  usage   of  telecommunications  services   by  organizations   and
individuals,   placing   additional  burdens   on   existing  telecommunications
infrastructures.
    
 
    Internationally, demand for better telecommunications services has increased
competition and resulted in privatization, investment in new infrastructures and
increased competition to provide better service. In less developed parts of  the
world,  carriers  are  implementing  new  systems  through  traditional landline
networks, new wireless technologies and other new technologies. Various  factors
have  further  contributed  to  acceleration  in  the  rate  of  growth  in  the
development of  the telecommunications  systems outside  of the  United  States,
including  the globalization of  business, the rise in  standards of living, the
increasing demand for reliable communications and the increasing deregulation in
the industry. Service providers in less  developed parts of the world  typically
are  building systems through the  purchase of equipment from  a wide variety of
suppliers, which results  in a  heterogeneous assortment of  switches and  other
network  hardware  and software.  This mix  generates a  need for  products that
support network operations  and can  be flexible  and adapted  to these  various
switches and system features. The Company's specialized knowledge and experience
with  a wide variety of switch equipment is particularly suited to meeting these
requirements.
 
    To develop, deploy and manage networks  and services, carriers rely on  OSSs
including  network  management  systems  ("NMS")  that,  among  other functions,
monitor equipment  performance  to  detect  errors  (fault  management),  report
network   performance  and  traffic  loads  (traffic  reporting),  help  in  the
performance of  market  research and  forecasting  and collect  and  consolidate
customer  usage information  (billing data  collection). Historically,  OSSs and
NMSs were  developed and  deployed in  an environment  characterized by  limited
competition  and slowly changing  technologies and services.  These systems were
typically mainframe-based, with proprietary software written in early generation
programming languages. As a result, these "legacy" systems were not designed for
rapid
 
                                       25
<PAGE>
deployment or adaptation, do not easily support heterogeneous equipment and  are
not  easily customized to fit  specific business needs. In  view of the industry
trends toward increased competition, technological complexity and rapid  change,
carriers require OSSs and NMSs that:
 
    - can  be  rapidly  deployed and  easily  adapted to  changing  business and
      network requirements;
 
    - interface with a wide  variety of existing  network equipment and  systems
      and accommodate new equipment and systems as they are deployed;
 
    - can  be tailored  through software  to provide  a variety  of OSS  and NMS
      functions; and
 
    - allow existing  networks to  accommodate  rapid growth  through  scaleable
      architecture.
 
OSSs  and NMSs that provide the foregoing benefits, and the products designed to
support them, will enable carriers to rapidly and cost effectively bring new and
enhanced services to market.
 
    ENTERPRISE NETWORKS
 
    The proliferation of new voice  and data services offered by  communications
companies  has increased the awareness of  and demand for network management and
billing systems. As  a result  of the growth  of network  usage and  competitive
pressures, enterprises in most industries have developed needs for sophisticated
NMSs,  which permit network managers to manage networks carrying different types
of voice  and data  communications  and to  lower  costs, manage  growth,  track
expenses and provide services without interruption.
 
    The  growing  dependence  on  intranets  and  the  Internet  to  support the
expanding information flow between offices, buildings and countries, both within
the enterprise  and to  and  from customers  and  suppliers of  the  enterprise,
requires  an efficient NMS to avoid the costly disruption of critical day-to-day
operations. Enterprises  increasingly rely  on e-mail,  phone mail,  facsimiles,
on-line  order entry, customer service  and telecommuting programs for employees
to transmit critical business information. For example, banks rely on  dispersed
automated  teller  machines to  conduct  banking transactions,  and  doctors and
hospitals rely on networks to transmit medical records and provide on-line care.
Furthermore, as  enterprises increase  the employment  of sophisticated  network
equipment  like  ATM,  Frame  Relay  and  X.25  data  switches,  it  will become
increasingly important for network managers to have the ability to charge  based
on  the amount of data transmitted. In cooperation with and funded by Newbridge,
the Company  is  developing  the  billing  component  for  their  advanced  data
switches.  The  billing  element  gives access  providers  flexible  options for
billing  users  of  data  network  services.  The  Company  anticipates  similar
opportunities  to  develop other  network  edge technologies  for  equipment and
service providers in the growing market for data services.
 
    Enterprises  which  require  NMSs  capable  of  handling  large  numbers  of
subscribers  efficiently,  reliably  and rapidly  include:  government agencies,
military  organizations,  educational  institutions  and  "Fortune  1000"   size
organizations. The NMS requirements of an organization become more sophisticated
as  the  number  of  subscribers,  locations,  users,  countries,  third parties
communicating with the organization, and types of hardware involved,  increases.
Network managers therefore require NMSs that provide:
 
    - the  ability  to  perform  high  volume  data  collection  and  to produce
      displays, graphics and  reports with  respect to  usage, surveillance  and
      management requirements;
 
    - the  ability  to manage  communications  over both  voice  circuits (e.g.,
      telephone, voice-mail) and data circuits (e.g., the Internet and  intranet
      connections,    e-mail,    facsimilies,    orders,    inventory   control)
      simultaneously;
 
    - the ability to bill for usage;
 
                                       26
<PAGE>
    - proprietary  and standard protocol  features which may  include the Simple
      Network Management Protocol ("SNMP");
 
    - compatibility  with   standard   network   management   platforms   (e.g.,
      Hewlett-Packard  Open  View,  IBM Netview  and  Sun Net  Manager)  and the
      ability to run under  standard operating systems  (e.g., UNIX, Windows  95
      and Windows NT); and
 
    - flexibility to accommodate expanding network management requirements.
 
    Telecommunications service providers benefit from the availability of timely
and  accurate  information  about  their  deployed  networks  because  it allows
increased  service  availability  without  increasing  network  investment.  The
Company  believes that advanced  products that support  their network operations
and sophisticated  network management  products are  important to  their  future
success.

evolving requirements of its customers. The Company works closely with customers
after  initial  implementation, to  enable  customers to  include  new features,
expand  into  additional  geographic  markets   or  operate  with  new   network
technologies  and protocols. In addition,  the Company provides ongoing support,
maintenance and training related to the customer's system.
 
STRATEGY
 
    The Company's objective is to be the  market leader in the markets in  which
it participates. The Company plans to achieve this objective by implementing the
following strategies:
 
   
    FOCUS ON NEW AND EMERGING GROWTH MARKETS.  The Company's principal marketing
emphasis is on two types of carriers: existing providers and emerging providers.
Existing  providers are replacing their older systems, augmenting their existing
systems to support  new features and  services or adding  new systems to  enable
them  to expand into new domestic  and international markets. Emerging providers
worldwide are  expected  to  offer  new  types  of  services  such  as  personal
communications  systems ("PCS") and  are entering existing  service markets that
have  been  recently   opened  to   competition  as   a  result   of  the   U.S.
Telecommunications  Act of 1996 and similar  legislation in other countries. The
Company believes that its experience in providing solutions to markets worldwide
within the carrier market, including local exchange, long distance and wireless,
involving applications for a  wide variety of  switches and other  heterogeneous
network system elements, provides it with a significant competitive advantage in
designing  products  which can  effectively handle  the  growing needs  of these
providers.
    
 
    EXPAND STRATEGIC  ALLIANCES.   The  Company  is strengthening  its  existing
strategic  alliances with  marketing partners  and creating  new alliances  as a
means of identifying new business opportunities
 
                                       27
<PAGE>
and   entering    new   markets.    These   strategic    alliances   are    with
internationally-recognized  telecommunications equipment  and service providers.
The alliances are  a critical component  of the Company's  strategy to  increase
penetration  in large international markets, by leveraging on the reputation and
marketing efforts of its partners.
 
   
    POSITION COMPANY PRODUCTS IN INTERNATIONAL  MARKETS.  Through its  alliances
with  internationally  focused  partners,  the Company  intends  to  continue to
identify new users in  emerging countries. Each  new installation represents  an
opportunity  for the Company to provide additional products and services for end
users. The Company has expanded its  opportunities by providing products to  one
type  of carrier  in a  country, often  a cellular  carrier, and  leveraging its
performance and reputation with  that customer to sell  products to other  local
carriers. The Company's experience with TELMEX is a model for this strategy. See
" -- Strategic Alliances and Other Customers."
    
 
   
    LEVERAGE  TECHNOLOGICAL  LEADERSHIP.   The  Company is  continually pursuing
opportunities to use its technological leadership to create product enhancements
such as real-time data collection and subscriber data warehousing. Recently, the
Company led a national effort for the development of a standard protocol for use
with the Microsoft Windows  operating system ("WinSNMP")  which is enabling  the
development  of  flexible,  decentralized data  network  management  systems. In
conjunction with this  effort, the  Company developed  enabling technology  that
facilitates  the use  of Microsoft Windows,  Intel processors  and the Company's
NetPlus products for managing  networks. To date, over  500 such kits have  been
sold  to  customers  such  as Microsoft  Corporation,  Oracle  Corporation, 3Com
Corporation, Lotus  Development Corporation,  CISCO Systems,  Inc. and  Symantec
Inc.  To further its penetration of the data network market, the Company is also
developing the  billing component  for advanced  data switches,  which  provides
access  providers  with  flexible  options for  billing  users  of  data network
services. The Company anticipates similar opportunities to develop other network
edge technologies for equipment and service providers in the growing market  for
data services.
    
 
    EXPAND  SOFTWARE  OPTIONS TO  MEET THE  NEEDS OF  ENTERPRISES.   The Company
continues to package its NetPlus software features into Company-standard systems
designed to work individually  or as a group  and to facilitate  enterprise-wide
voice  and  data communications.  The Company  is also  expanding the  number of
available features to support data  communications networks and operations.  The
Company  believes it will be particularly  important to provide network managers
with the flexibility to meet the increasing demands of converging voice and data
telecommunications markets and expanding enterprise network requirements.

international  quality standard ISO 9001. This standard assures that the Company
meets  rigorous   performance   and   quality   criteria   established   by   an
internationally  recognized  organization.  Compliance  with  this  standard  is
particularly  important   in   establishing  credibility   and   acceptance   in
international markets.
 
PRODUCTS
 
    All  of the following products reflect  the Company's extensive knowledge of
switch interface technology and experience  in the collection and management  of
data  from switches made by virtually  any manufacturer. The Company has applied
the same expertise to network  management products for large enterprises,  whose
complex  networks often involve remote  locations and require similarly flexible
and innovative designs to facilitate the flow of communications.
 
    CARRIER NETWORK PRODUCTS
 
    The Company's carrier network products meet the requirements of the existing
telephony wireline businesses and the  growing markets of cable television,  the
Internet  and wireless businesses. The automation of data collection from remote
switches enables carriers to operate  larger, increasingly complex systems  with
more  customer  features more  reliably, more  cost  effectively and  with fewer
personnel. The Company's  carrier network  products are  designed to  facilitate
more accurate and more
 
                                       28
<PAGE>
frequent  billing, thereby  reducing billing  lag time  and accounts receivable.
They also enable carriers to track calling patterns, reduce fraud, perform fault
management,  improve  network  performance,  and  verify  that  calls  are   not
needlessly  routed through inefficient or expensive paths. These products enable
a carrier to  increase the size  of its system  and provide its  end users  with
better   service,  in   remote  and   international  locations.   Following  are
descriptions of the Company's principal carrier network products:
 
    DATA COLLECTION
 
        DCMS-REGISTERED  TRADEMARK-  --   DCMS,  Distributed  Call   Measurement
    System-TM-,  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
    detection.  DCMS  eliminates magnetic  tape  storage units  and  manual data
    collection, reduces processing costs, and increases the accuracy of  billing
    data  which, in  turn, increases revenue.  The most recent  version of DCMS,
    NEDS-TM-, Network Element Data Server, can  provide the data on a  real-time
    basis. The Company also offers the DCMS*Plus-TM-, a version of DCMS which is
    based  on a  new technology  platform and is  targeted at  carriers in third
    world and  emerging countries.  These  products can  be adapted  to  support
    virtually all wireline and wireless telephone switches.
 
    BILLING REPORTS AND ACCESS TO CUSTOMER DATA
 
        UPS-32-REGISTERED TRADEMARK- -- UPS-32, Universal Polling System-32-TM-,
    is  a mini-computer, server  or PC-based product,  programmed 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-TM-, Central Access
    Network Server, collects and distributes data in real-time.
 
        TIBS-TM-  --   TIBS,  TELMARS-TM-   International  Billing   System,   a
    software-based alternative carrier billing system, uses information gathered
    by  the  DCMS or  other providers'  data  collection products,  and provides
    carriers  with  billing  information.  TIBS  is  designed  to  reliably  and
    accurately  bill for subscriber calls originating  in over 30 countries, and
    to support accurate currency conversions based on daily exchange rates.
 
        TREX*COMM-TM- -- TREX*COMM is a software-based product designed for U.S.
    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  automates  the  transfer of
    CENTREX call usage data from remote switch sites to customers' equipment and
    sorts records  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, TREX*COMM
    makes network information available to CENTREX subscribers to enable them to
    manage and control data.

    from the network elements. The Company presently is adding standard  network
    management protocols to ANMS.
 
    NETWORK MANAGEMENT PRODUCTS
 
   
    The  Company's network management products  meet the requirements of network
managers of large, growing  and increasingly complex  integrated voice and  data
networks.  The Company's network management products  are designed to enable the
managers to operate their networks more effectively, to more accurately  control
costs,  to minimize network down time, and to implement other network management
features as their requirements grow and change.
    
 
   
        NETPLUS-REGISTERED TRADEMARK- 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  voice  and data
    networks for  1,000  to 50,000  users.  The Company  also  licenses  NetPlus
    software  to resellers to reach the  market for small size networks. NetPlus
    products are capable of providing total network management including: FAULT,
    CONFIGURATION, ACCOUNTING,  PERFORMANCE AND  SECURITY MANAGEMENT  ("FCAPS").

    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.
    
 
SALES AND MARKETING
 
    Historically, the Company's sales and marketing efforts have been managed by
a   small  group  of   senior  managers  with   substantial  experience  in  the
telecommunications  service  provider  market.  These  managers  relied  on  the
Company's   proven  performance  in  promoting  the  Company's  products.  Sales
opportunities originated primarily from (i) referrals, (ii) involvement in trade
shows and  industry  conferences,  (iii) responses  to  Requests  for  Proposals
received  from  telecommunications  service  providers,  governments  and  other
organizations and  (iv) leads  from  or contract  proposals with  the  Company's
strategic alliance partners. See "-- Strategic Alliances and Other Customers."
 
    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.
 
    As  part of its sales  strategy, the Company spends  a significant amount of
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.
 
    At  present, the Company  plans to significantly  increase its sales efforts
over the  next six  to 12  months through  more aggressive  sales and  marketing
strategies. The Company is hiring more
 
                                       30
<PAGE>
direct,  experienced  sales  representatives,  adding  third  party distribution
channels  and  developing  additional  strategic  alliances  with  carriers  and
communications equipment manufacturers to market the Company's products.
 
   
    The  Company's products typically  are sold as  part of systems  sold to the
customers of strategic partners. Resellers are also used to target markets where
large numbers  of customers  with  smaller networks  are predominant.  A  small,
direct sales force markets the Company's products in markets where relationships
are  not established. The Company is in the process of identifying and targeting
the markets most likely  to need its  products. To date, as  a result of  market
research  and analysis,  the Company  has begun  to actively  market its network
management products to universities and airports. The Company also plans certain
promotional efforts targeted at identified potential enterprise customers,  such
as   through  participation  at  the   Association  of  College  and  University
Telecommunications Administrators conference and  other national conferences  on
network management and billing.
    
 
    The  Company is working with several manufacturers to promote the visibility
and positioning of its network management products. As a leader in the promotion
of SNMP, which is emerging as  an industry standard for network management,  the
Company has sold licenses to various suppliers, including Microsoft Corporation,
3Com  Corporation, CISCO  Systems, Inc.,  Lotus Development  Corporation, Oracle
Corporation and Symantec  Inc., enabling  them to incorporate  WinSNMP in  their
products  for use in  establishing network management  applications, which could
include NetPlus products.
 
    The Company plans to increase  its promotional and name recognition  efforts
over the next 12 months. It will continue to exhibit in trade shows and industry
conferences,  publish newsletters and hold user  group meetings. The Company has
also established a home page on  the Internet to communicate with customers  and
prospects.
 
CUSTOMER SUPPORT
 
    The  Company  believes  that a  high  level of  engineering  and development
services and customer support is critical to the Company's continuing success in
developing relationships with its strategic  partners and end users. To  augment
its   sales  efforts,   the  Company  offers   product-related  engineering  and
development services  to its  customers. The  Company offers  a range  of  other
services  to  customers,  including requirements  analysis,  project management,
system  design,  tailoring  and  installation,  training,  ongoing  support  and
upgrades.  Because the Company's services personnel work closely with customers,
they are able to gain valuable industry expertise, as well as identify  emerging
industry applications. In addition, the Company's services personnel are able to
identify  new sales opportunities.  When the Company  undertakes engineering and
development services for  customers, the  development often  results in  product
enhancement.
 
    The  Company offers technical customer support  24 hours per day, seven days
per week.  Support is  provided  via telephone,  remote  login, e-mail  and,  if
necessary,  on-site assistance. In addition, the Company has established a World
Wide Web  site  on  the  Internet which  keeps  customers  informed  of  product
developments.  International customers are supported  directly by the Company or
by local representatives that have been trained by the Company. The Company also
conducts training classes for its strategic partners and other customers.
 
STRATEGIC ALLIANCES AND OTHER CUSTOMERS
 
    In order to distribute its products effectively, the Company has established
strategic alliances with  several companies. The  Company's strategic  alliances
apply  to both its carrier network products and its network management products.
Each alliance is designed to do one or more of the following: establish a  joint
marketing  relationship, create a reseller  channel for products, facilitate the
development of  products  and facilitate  the  distribution of  products.  These
alliances  have been especially helpful in enabling the Company to penetrate, on
a cost-effective  basis, international  markets,  where the  Company's  alliance
partners are well known and have well developed business relationships.
 
                                       31
<PAGE>
    Typically, the Company enters into a formal agreement with the partner which
specifies  product pricing and  the responsibilities of  each partner for system
integration, proposal drafting and  marketing. The Company's partners  generally
include ACE*COMM products in proposals to their customers in accordance with the
terms of these agreements. In some instances, the partner is the direct end user
of the Company's products.
 
   
    The  Company's carrier network products have  been installed in over 500 end
user sites in 32 countries. The Company's three largest carrier network  product
customers, including strategic alliance partners and end users, in each of 1994,
1995  and 1996 accounted for approximately 24.6%, 43.0% and 42.8%, respectively,
of the Company's revenues in each of such years.
    
 
   
    The Company's network management  products have been  installed in over  100
end  user  sites  in 10  countries.  Network management  products  accounted for
approximately 59.4%, 37.1% and 32.1% of the Company's revenues in 1993, 1994 and
1995, respectively. Sales to ANSTEC during fiscal year 1996 represented 11.3% of
the Company's total revenues for that period.
    
 
    The following  is  a  list  of  the  Company's  most  significant  strategic
alliances:

    The following is  a list  of some of  the Company's  other most  significant
customers  that  have  installed  the  Company's  carrier  network  and  network
management products within their organizations:
 
        - TELEFONOS DE MEXICO, S.A.  DE C.V. -- TELMEX,  the national and  local
          long  distance carrier of Mexico, selected the Company to upgrade data
          collection  throughout  its  switch  network  system.  The  three-year
          contract has an estimated value of $12 million.
 
        - GTE  TELOPS (A  DIVISION OF GTE  TELEPHONE COMPANY)  -- purchased DCMS
          systems for installation on certain switch types through its network.

                                       33
<PAGE>
    In  addition,  companies  such  as  ISI  Infortext  Inc.,  Computer  Science
Corporation,  Polaris  Communication Services,  Inc. and  Telsoft International,
Inc. have agreed to promote and  sell the Company's products on a  non-exclusive
basis. They participate in trade shows, industry conferences and customer events
and feature ACE*COMM products in their marketing programs.
 
    As  more  ATM, Frame  Relay  and X.25  data  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. The Company
is  developing a  billing component for  advanced data  switches, which provides
access providers  with  flexible  options  for billing  users  of  data  network
services. The Company anticipates similar opportunities to develop other network
edge  technologies for equipment and service providers in the growing market for
data services.
 
    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.
 
BACKLOG
 
   
    The  Company tracks two types of  backlog: "order backlog," which represents
signed purchase orders, and "contract backlog," which represents signed  project
contracts  that  become  order backlog  upon  the signing  of  specific purchase
orders. Order backlog was approximately  as follows: $5.7 million, $3.6  million
and  $10.4  million, at  June 30,  1994, 1995  and 1996,  respectively. Contract
backlog was approximately: $2.6 million, $1.0 million and $37.2 million at  June
30, 1994, 1995 and 1996, respectively.
    
 
   
    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 typically is 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. No assurance
can be given that current backlog will necessarily lead to revenue in any 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  carrier market and of  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 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  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 Securicor Telesciences, Inc., CGI, Inc. ("CGI"), and IDT
- - Alston 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  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, 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 both 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  than  the  Company.  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 carriers and enterprises 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,  often  in cooperative
funding arrangements.  For example,  the Company  is working  with Newbridge  to
develop  new  software for  its data  switch  products. The  Company continually
reviews  opportunities  to   license  technologies  from   third  parties   when
appropriate  based on timing and cost  considerations. The Company believes that
this approach facilitates and  accelerates the development  of new and  enhanced
products.
 
    The  Company's efforts are influenced significantly by industry developments
and by  customer  and  end  user requirements.  New  features  may  be  tailored
initially  for delivery to a single  customer and subsequently incorporated into
future versions of the product which are available to all customers.
 
   
    During  the  fiscal  years  1994,  1995  and  1996,  product  research   and
development   expenses  were  $0.6  million,  $1.0  million  and  $1.0  million,
respectively.
    
 
PROPRIETARY RIGHTS AND LICENSES
 
    The Company does not currently hold any patents and relies on a  combination
of  statutory and/or common law, copyright, trademark, contract and trade secret
laws 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
 
                                       35
<PAGE>
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 a copyrighted work.
 
EMPLOYEES
 
   
    At  June 30, 1996, the Company employed  a total of 137 employees, including
34  involved  in  manufacturing  and  quality  assurance,  29  in  research  and
development,  23 in sales and  marketing, 16 in professional  services and 35 in
administration and finance. None of the Company's employees is represented by  a
labor union. The Company has experienced no work stoppages and believes that its
employee relations are good.

BOARD COMMITTEES AND COMPENSATION
 
    The Board of Directors has established an Audit Committee and a Compensation
Committee.  The  Audit  Committee  oversees  actions  taken  by  the   Company's
independent  auditors,  recommends the  engagement of  auditors and  reviews any
internal audits  the Company  may  perform. The  current  members of  the  Audit
Committee  are Messrs.  Golding, Wetzel  and Casner.  The Compensation Committee
approves the compensation of executives of the Company, makes recommendations to
the Board of Directors with respect to standards for setting compensation levels
and administers  the Company's  Amended  and Restated  Omnibus Stock  Plan  (the
"Stock  Plan"). The  current members of  the Compensation  Committee are Messrs.
Golding, Wetzel and Casner, none of whom is employed by the Company.
 
   
    Directors are reimbursed for  their travel expenses  in attending Board  and
Committee  meetings. Each of the Company's current non-employee directors (other
than Mr.  Golding)  was  granted an  option  to  purchase 4,500  shares  of  the
Company's  Common Stock at an  exercise price of $1.55  per share on December 9,
1995, pursuant to  the Company's Amended  Stock Option Plan  for Directors  (the
"Directors  Stock  Plan"). Only  non-employee directors  may participate  in the
Directors Stock Plan. The plan authorizes  the issuance of up to 200,000  shares
of Common Stock, subject to adjustment to reflect stock splits, recapitalization
and  other changes in the outstanding  stock. Each eligible director is entitled
under the plan  to receive  upon his  election or  reelection as  a director  an
option  for a number of shares equal to  4,500 multiplied by the number of years
in the term for which he is  then elected, exercisable at the fair market  value
of  the Common  Stock on the  date of  grant. The option  becomes exercisable in
equal installments of 4,500 shares on each anniversary of the date of grant  or,
on  such earlier  date as  the director ceases  to be  a director  other than by
reason of his  removal for  cause, if  such date  is 15  days prior  to such  an
anniversary date and such director has served at least 12 months in office. Each
option  expires  upon the  earlier of  five years  from the  date of  grant, the
expiration of six months following death, resignation or removal other than  for
cause, or upon removal of a director for cause.

(1) Value  realized  represents  the  positive  spread  between  the  respective
    exercise prices of the exercised options and the fair market value per share
    on the respective dates of exercise.
    
 
   
(2) Value for "in-the-money" options represent  the positive spread between  the
    respective  exercise prices  of outstanding  options and  an assumed initial
    public offering price of  $10.00 per share (the  mid-point of the  estimated
    range of the initial public offering price).
    
 
AMENDED AND RESTATED OMNIBUS STOCK PLAN
 
   
    The  Company has adopted,  subject to stockholder  approval, the Stock Plan.
The maximum number  of shares of  Common Stock in  respect of which  stock-based
awards  may be granted under  the Stock Plan is  2,200,000. The shares of Common
Stock to be delivered under the plan will be made available from the  authorized
but unissued shares of Common Stock.
    
 
    The  Stock Plan  will be administered  by the Compensation  Committee of the
Board of Directors (the "Committee"), upon  which no director who is an  officer
of   the  Company  may  serve,  and  which  comprises  only  Directors  who  are
"non-employee directors"  within the  meaning of  Rule 16b-3  of the  Securities
Exchange  Act of  1934, as  amended (the "Exchange  Act"), and  who are "outside
directors" within the meaning of Section 162(m) of the Internal Revenue Code  of
1986,  as amended (the "Code"). All employees of the Company, including employee
directors, are eligible to participate in the Stock Plan. It is anticipated that
the Committee's determinations  of which  eligible individuals  will be  granted
awards  and the  terms thereof  will be based  on each  individual's present and
potential contribution to the success of the Company.
 
   
    Stock options may be granted under the  Stock Plan at the discretion of  the
Committee  and subject to such terms  and conditions determined by the Committee
and set forth in a grant agreement. Options granted under the Stock Plan may  be
either  nonqualified  options  or  incentive stock  options.  The  Committee has
discretion to fix the exercise  price of such options at  a price not less  than
100%  of the fair market  value of the underlying shares  of Common Stock at the
time of grant thereof. The  Committee has broad discretion  as to the terms  and
conditions  upon which options shall be  exercisable, but under no circumstances
will an incentive  stock option  have a  term exceeding  10 years  from date  of
grant.
    
 
   
    The  option exercise price may be satisfied in cash or, in the discretion of
the Committee, by exchanging shares of Common Stock owned by the optionee, by  a
combination  of cash and  shares of Common Stock  or by such  other means as the
Committee may prescribe. The ability to pay the option exercise price in  shares
of  Common Stock  would, if  permitted by the  Committee, enable  an optionee to
engage in  a  series  of  successive  stock-for-stock  exercises  of  an  option
(sometimes  referred to  as "pyramiding") and  thereby fully  exercise an option
with little or no cash investment. The Company also may make or guarantee  loans
to optionees to assist optionees in exercising stock options.
    
 
                                       40
<PAGE>
    The  terms of an option may provide for  the automatic grant of a new award,
exercisable for not more  than the number of  shares tendered when the  exercise
price of the option and/or related tax obligation is paid by tendering shares of
Common  Stock (sometimes  referred to as  "reload options"),  subject to certain
limitations set forth in the Stock Plan.
 
   
    Incentive stock option awards under the Stock Plan must comply with  Section
422 of the Code. Incentive stock option awards made to an optionee who owns more
than  10% of the  outstanding stock of  the Company must  have an exercise price
that is not less than 110% of the fair market value of the underlying shares  on
the  date of  grant, a  term not  exceeding five  years, and  the aggregate fair
market value of shares of Common Stock with respect to which all incentive stock
options first  become exercisable  by an  optionee in  any calendar  year  shall
either not exceed $100,000 or be treated as non-qualified options.
    
 
   
    The Committee also may grant stock appreciation rights. Upon the exercise of
a  stock  appreciation  right  with  respect  to  a  share  of  Common  Stock, a
participant would be entitled to receive the excess of the fair market value  of
such  shares  over the  base  price of  such right,  which  is specified  by the
Committee upon grant and may not be less  than 100% of the fair market value  of
the  underlying shares at the date of  grant. The Committee has the authority to
determine whether the value  of a stock  appreciation right is  paid in cash  or
shares of Common Stock or a combination of both.
    
 
   
    The  Committee also has discretion to  make contingent grants of performance
shares which will be earned to  the extent performance goals established by  the
Committee  are achieved over  a period of  time specified by  the Committee. The
Committee will have discretion to determine the value of each performance share,
to adjust  the  performance  goals  as it  deems  equitable  to  reflect  events
affecting  the  Company or  changes  in law  or  accounting principles  or other
factors, and  to determine  the number  of performance  shares which  have  been
earned  based on  performance relative to  such performance goals.  The value of
performance shares that are earned may,  in the discretion of the Committee,  be
paid in the form of cash, shares of Common Stock, or a combination of both.
    
 
   
    Awards  of stock under the Stock Plan will  be made at the discretion of the
Committee and may  be subject  to forfeiture  and restrictions  on transfer.  In
general,  a participant who has been granted restricted stock will from the date
of grant have the benefits of ownership in respect of such shares, including the
right to  vote such  shares and  to receive  dividends and  other  distributions
thereon,  subject to  the restrictions set  forth in  the Stock Plan  and in the
instrument evidencing such award. The shares of restricted stock will be held by
the Company,  or  by an  escrow  agent designated  by  the Company,  during  the
restricted  period  and  may not  be  sold, assigned,  transferred,  pledged, or
otherwise encumbered  until  the restrictions  have  lapsed. The  Committee  has
authority  to determine the duration of the restricted period and the conditions
under which stock may be forfeited, as well as the other terms and conditions of
such awards.
    
 
   
    The Stock Plan also authorizes the Committee to grant to participants awards
that are valued in whole or in part by reference to, or are otherwise based  on,
the  value of shares  of Common Stock  ("Stock Unit Awards").  The Committee has
discretion to determine  the participants to  whom Stock Unit  Awards are to  be
made,  the times at which such  awards are to be made,  the size of such awards,
and all other conditions  of such awards,  including any restrictions,  deferral
periods,  or performance requirements.  The provisions of  the Stock Unit Awards
will be subject to such rules  and regulations as the Committee shall  determine
at the time of grant.
    
 
    Any  award under  the Stock  Plan may provide  that the  participant has the
right to  receive  currently  or  on a  deferred  basis  dividends  or  dividend
equivalents  and/or other cash payments in addition to or in lieu of such award,
all as the Committee shall determine.
 
    If the Committee determines  that any stock split,  stock dividend or  other
distribution  (whether  in the  form of  cash,  securities, or  other property),
recapitalization, reorganization,  merger,  consolidation,  split-up,  spin-off,
combination,  repurchase or  exchange of shares,  issuance of  warrants or other
rights to purchase shares at a price  below fair market value, or other  similar
corporate event affects
 
                                       41
<PAGE>
the  Common Stock such that  an adjustment is required  in order to preserve the
benefits intended under  the Stock Plan,  then the Committee  has discretion  to
make  (i) equitable adjustments (a) in the number and kind of shares that may be
the subject of future awards under the Stock Plan or (b) the number and kind  of
shares  (or other securities or property)  subject to outstanding awards and the
respective grant  of exercise  prices thereof  and/or, (ii)  if appropriate,  to
provide for the payment of cash to a participant.
 
   
    The  Committee has broad discretion as  to the specific terms and conditions
of each award and any rules applicable thereto, including but not limited to the
effect thereon of the death, retirement,  or other termination of employment  of
the  participant and the effect, if any, of  a change in control of the Company.
The terms of each award are to be evidenced by a written instrument delivered to
the participant.  The awards  authorized under  the Stock  Plan are  subject  to
applicable  tax  withholding  by  the  Company which  may  be  satisfied  by the
withholding of shares issuable under the Stock Plan.
    
 
    No award may be granted under the Stock Plan after the tenth anniversary  of
the effective date of the Stock Plan.
 
    The  Stock Plan  may be amended  or terminated at  any time by  the Board of
Directors, except that no amendment may be made without stockholder approval  if
such  approval is  necessary to comply  with any tax  or regulatory requirement,
including any approval requirement which is a prerequisite for exemptive  relief
from Section 16 of the Exchange Act.
 
   
    The  Stock Plan is not  subject to any provision  of the Employee Retirement
Income Security Act  of 1974,  as amended, and  is not  qualified under  Section
401(a) of the Code.
    
 
    Special  rules apply to  a participant who  is subject to  Section 16 of the
Exchange Act. Certain additional special rules  apply if the exercise price  for
an  option is paid  in shares of  Common Stock previously  owned by the optionee
rather than in cash.
 
   
    Counsel has provided  the Company with  the following brief  summary of  the
Federal  income  tax consequences  under the  Code as  currently in  effect with
respect to (i)  incentive stock  options, (ii) non-qualified  stock options  and
(iii) restricted stock awards:
    
 
   
    (i)  INCENTIVE STOCK OPTIONS.  No taxable income is realized by the optionee
upon  the  grant or  exercise of  an incentive  stock option.  If there  were no
disposition of the option shares until more  than two years after the option  is
granted  and more than one year after the  option is exercised, the gain or loss
realized by  the  optionee on  the  sale of  such  shares would  be  treated  as
long-term  capital gain or  loss, and the  Company would not  be entitled to any
income tax deduction by reason  of the grant or exercise  of the option. If  the
option shares were disposed of in a sale, exchange, gift or other "disqualifying
disposition" prior to the expiration of the
two-years-from-grant/one-year-from-exercise  holding  period, generally  (a) the
optionee would realize taxable ordinary income  in the year of such  disposition
in  an amount  equal to the  excess (if  any) of the  fair market  value of such
shares at the  time of  exercise of  the option  over the  option price  thereof
(except  that, if the disposition is  a sale or exchange of  the type on which a
loss, if sustained, would be recognized to such optionee, ordinary income  would
be  realized by such  optionee in an amount  equal to only  the gain realized on
such sale or exchange if such gain  is less than such excess) and would  realize
capital  gain on the balance of the gain, and (b) the Company generally would be
entitled to a  deduction for such  year in  the amount of  the ordinary  taxable
income to the optionee.
    
 
   
    (ii)   NON-QUALIFIED OPTIONS.  No taxable income is realized by the optionee
upon the grant of a  non-qualified option. On exercise,  the excess of the  fair
market value of the shares at the time of exercise over the option price of such
shares  would  be  treated  as  compensation.  Special  rules  may  apply  to  a
participant who  is subject  to Section  16  of the  Exchange Act.  Any  amounts
treated as compensation (a) would be taxable at ordinary income tax rates in the
year  of exercise, (b)  would be subject  to withholding for  Federal income tax
purposes, and (c) generally  would be an allowable  income tax deduction to  the
Company.  The  optionee's  tax basis  for  shares  acquired upon  exercise  of a
    
 
                                       42
<PAGE>
   
non-qualified option would be equal to the option price paid for the shares plus
any amounts treated as compensation. An optionee would generally be entitled  to
capital  gain treatment  on the  difference between his  tax basis  and the sale
price of the shares acquired upon exercise.
    
 
   
    (iii)  RESTRICTED STOCK AWARDS.  No income would be realized by an  employee
in  connection with the grant of a restricted stock award. When the restrictions
lapse, the employee would be required to include as taxable ordinary income  the
fair market value of such shares at the time the restrictions lapse. The Company
would  be entitled to a  deduction for Federal income  tax purposes equal to the
amount so  included in  such employee's  income. An  employee may,  by making  a
Section  83(b) election within  30 days after  the transfer of  stock, choose to
recognize income upon the grant of a restricted stock award. Any appreciation in
the stock value after the grant date will be eligible for capital gain treatment
upon the subsequent sale of the stock. However, if the stock is forfeited later,
the loss deduction allowable is limited to the price paid for the stock (if any)
minus any amounts received upon such forfeiture.
    
 
   
    (iv)  PAYMENT OF WITHHOLDING TAXES.  The Company may withhold, or require  a
participant  to  remit  to the  Company,  an  amount sufficient  to  satisfy any
Federal, state and local withholding tax requirements. The Committee may  permit
a  participant to satisfy a tax withholding requirement on exercise of an option
by delivery  to  the  Company  of  shares of  its  Common  Stock  owned  by  the
participant,  including  shares  the  participant is  entitled  to  receive upon
exercise of the option.
    
 
   
    (v)   CODE SECTION  162(M).   Section  162(m) of  the  Code limits  the  tax
deduction   available  for  compensation   paid  to  the   Company's  five  most
highly-compensated  individuals  in   excess  of  $1,000,000.   To  the   extent
practicable,  awards under the Stock Plan  to designated executives will qualify
as "performance-based" compensation  which is excluded  from the Section  162(m)
cap  on deductibility. Stock options and  stock appreciation rights issued under
the Stock Plan are expected to be fully deductible as performance-based.
    
 
    (vi)  OTHER.   To the extent  payments which are contingent  on a change  in
control  are determined to exceed certain  Code limitations, they may be subject
to a 20% nondeductible  excise tax and the  Company's deduction with respect  to
the associated compensation expense may be disallowed in whole or in part.
 
    The  foregoing discussion summarizes the  Federal income tax consequences of
the Stock Plan  based on current  provisions of  the Code which  are subject  to
change.  This summary  does not  cover any  state or  local tax  consequences of
participation in the Stock Plan.
 
EMPLOYMENT AGREEMENTS AND CHANGE IN CONTROL ARRANGEMENTS
 
    The Company currently  has no  employment contracts  with any  of the  Named
Executive Officers, and the Company has no compensatory plan or arrangement with
such  Named Executive Officers where the amounts  to be paid exceed $100,000 and
which are  activated upon  resignation, termination  or retirement  of any  such
executive officers upon a change in control of the Company.
 
LIMITATION ON LIABILITY OF DIRECTORS
 
    The  Charter  provides that  a director  will not  be personally  liable for
monetary damages to the Company or its stockholders for breach of fiduciary duty
as a director, except to the  extent such exemption for liability or  limitation
thereof  is not  permitted under Maryland  law, including liability  (i) for any
breach of the  director's duty of  loyalty to the  Company or its  stockholders,
(ii)  for  acts or  omissions not  in  good faith  or which  involve intentional
misconduct or  a  knowing violation  of  law, (iii)  for  paying a  dividend  or
approving  a  stock repurchase  in violation  of Section  2-311 of  the Maryland
Corporation Law or (iv) for any  transaction from which the director derived  an
improper personal benefit.
 
    While  the Charter  provides directors  with protection  from having  to pay
monetary damages for breaches of their duty of care, it does not eliminate  such
duty.  Accordingly,  the Charter  will  have no  effect  on the  availability of
equitable remedies such  as an injunction  or rescission based  on a  director's
 
                                       43
<PAGE>
breach of his or her duty of care. The provisions of the Charter described above
apply  to an  officer of  the Company  only if he  or she  is a  director of the
Company and is acting in his capacity as director, and do not apply to  officers
of the Company who are not directors.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The  Charter provides that the Company  shall indemnify its currently acting
and its  former officers  and  directors against  any  and all  liabilities  and
expenses  incurred in connection  with their services in  such capacities to the
maximum extent permitted  by Maryland  law, as from  time to  time amended.  The
Charter  further provides that  the right to  indemnification shall also include
the right to be paid by the Company for expenses incurred in connection with any
proceeding arising out of  such service in advance  of its final disposition  to
the fullest extent permitted by Maryland law.
 
    The Charter further provides that the Company may, by action of its Board of
Directors,  provide indemnification to  such of the employees  and agents of the
Company and  such other  persons serving  at the  request of  the Company  as  a
director,  officer, partner, trustee, employee  or agent of another corporation,
partnership, joint venture,  trust, or other  enterprise to such  extent and  to
such  effect as is  permitted by Maryland  law and the  Board of Directors shall
determine to be appropriate.
 
    The Company expects  to purchase  and maintain  insurance on  behalf of  any
person  who is or was a director, officer, employee, or agent of the Company, or
is or was serving at the request of the Company as a director, officer, employee
or agent of  another corporation,  partnership, joint venture,  trust, or  other
enterprise  against any expense,  liability, or loss incurred  by such person in
any such capacity  or arising  out of  his status as  such, whether  or not  the
Company  would  have the  power to  indemnify him  against such  liability under
Maryland law.
 
    The Charter  provides  that (i)  the  Board  of Directors  may,  by  by-law,
resolution   or  agreement,  make  further   provision  for  indemnification  of
directors, officers, employees and agents and (ii) no amendment, modification or
repeal of  the Charter,  nor the  adoption of  any additional  provision of  the
Charter or the By-laws nor, to the fullest extent permitted by Maryland law, any
amendment, modification or repeal of law shall eliminate or reduce the effect of
the provisions in the Charter limiting liability or indemnifying certain persons
or  adversely affect any right or protection then existing thereunder in respect
of any  acts  or omissions  occurring  prior to  such  amendment,  modification,
repeal, or adoption.
 
                              CERTAIN TRANSACTIONS
 
   
    In  connection with  the purchase  of certain assets  by the  Company at its
inception, Mr. Jimenez, the Company's  President loaned $150,000 to the  Company
to  assist in financing the acquisition. The  note bears interest at the federal
short-term rate  established periodically  by the  U.S. Treasury.  Principal  is
payable upon demand and interest is paid quarterly. The outstanding loan balance
was $78,572 at June 30, 1996 and will be entirely repaid out of proceeds of this
offering. See "Use of Proceeds."
    
 
   
    During  fiscal  years  1994,  1995 and  1996,  the  Company  purchased voice
processing systems  totaling approximately  $1,036,000, $62,000,  and  $212,000,
respectively,  from Microlog Corporation ("Microlog"),  a company whose Board of
Directors included Mr. Jimenez, the Company's President, and Graham Hartwell,  a
former  Director of the  Company. Mr. Jimenez resigned  from Microlog's Board of
Directors in January  1994.  Mr.  Hartwell retired from  the Company's Board  of
Directors  in December 1995. The Company expects to continue to do business with
Microlog on terms no less favorable to  the Company than could be obtained  from
an unaffiliated third party.
    
 
    The  Company believes that all of the transactions set forth above were made
on terms no less  favorable to the  Company than could  have been obtained  from
unaffiliated  third parties. All further  transactions, including loans, between
the Company  and  its  officers, directors,  principal  shareholders  and  their
affiliates will be approved by a majority of the Board of Directors, including a
majority  of  the  independent  and  disinterested  outside  directors  and will
continue to be, in the judgment of  such a majority, on terms no less  favorable
to the Company than could be obtained from unaffiliated third parties.

                       PRINCIPAL AND SELLING STOCKHOLDERS
 
   
    The  following  table sets  forth  certain information  regarding beneficial
ownership of the Common Stock  as of June 30, 1996,  and as adjusted to  reflect
the  sale of shares offered hereby, by (i) each stockholder known by the Company
to be a beneficial owner of more than five percent of the Common Stock, (ii) the
Selling Stockholder, (iii)  each of the  Company's directors, (iv)  each of  the
Named  Executive Officers  and (v) all  directors and executive  officers of the
Company as a  group. Except as  indicated in  the footnotes to  this table,  the
Company  believes that  the persons  and entities named  in the  table have sole
voting and investment power with respect to all shares of Common Stock shown  as
beneficially owned by them, subject to community property laws where applicable.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
    Upon  the completion  of this  offering, the  Company will  be authorized to
issue 45,000,000 shares of Common Stock, $.01 par value, and 5,000,000 shares of
undesignated Preferred Stock, $.01 par value.
 
COMMON STOCK
 
   
    As of June 30, 1996, there were 3,590,451 shares of Common Stock outstanding
held of record by 26 stockholders. As  of June 30, 1996, options to purchase  an
aggregate  of 1,073,704  shares of Common  Stock were also  outstanding of which
options to purchase  938,704 shares  were then exercisable.  See "Management  --
Amended  and Restated Omnibus Stock Plan." After giving effect to the conversion
of all outstanding shares  of Class C Preferred  Stock into 1,530,950 shares  of
Common  Stock and the sale of 2,270,000 shares of Common Stock by the Company in
this offering,  there  will be  7,391,401  shares of  Common  Stock  outstanding
(7,766,401  shares if  the Underwriters'  over-allotment option  is exercised in
full).
    
 
    The holders  of Common  Stock are  entitled to  one vote  per share  on  all
matters  to be voted on  by shareholders and have  cumulative voting rights with
respect to the election of directors. Subject to the prior rights of holders  of
Preferred  Stock, if any,  the holders of  Common Stock are  entitled to receive
such dividends, if any,  as may be declared  from time to time  by the Board  of
Directors  in  its  discretion  from  funds  legally  available  therefor.  Upon
liquidation or dissolution of  the Company, the remainder  of the assets of  the
Company  will be  distributed ratably  among the  holders of  Common Stock after
payment of liabilities and the liquidation preferences of any outstanding shares
of Preferred Stock.  The Common Stock  has no preemptive  or other  subscription
rights  and  there  are  no  conversion rights  or  redemption  or  sinking fund
provisions with respect to such shares. All of the outstanding shares of  Common
Stock  are, and the shares to  be sold in this offering  will be, fully paid and
nonassessable.
 
PREFERRED STOCK
 
   
    The Board of Directors has the authority to issue the Preferred Stock in one
or more  series  and to  fix  the  price, rights,  preferences,  privileges  and
restrictions  thereof,  including  dividend rights,  dividend  rates, conversion
rights, voting  rights,  terms  of redemption,  redemption  prices,  liquidation
preferences and the number of shares constituting a series or the designation of
such  series, without any further vote  or action by the Company's shareholders.
The issuance  of  Preferred  Stock, while  providing  desirable  flexibility  in
connection  with possible acquisitions and  other corporate purposes, could have
the effect  of delaying,  deferring or  preventing a  change in  control of  the
Company  without further action by the shareholders and may adversely affect the
market price of,  and the  voting and  other rights  of, the  holders of  Common
Stock.  The Company has no current plans to issue any shares of Preferred Stock.
Upon consummation of  this offering,  the conversion  of the  Class C  Preferred
Stock  and  the redemption  of the  Class B  Preferred Stock,  there will  be no
Preferred Stock outstanding.
    
 
BUSINESS COMBINATIONS
 
    Maryland law prohibits certain "business combinations" (including a  merger,
consolidation,  share exchange, or, in  certain circumstances, an asset transfer
or issuance or reclassification of equity
 
                                       46
<PAGE>
   
securities) between  a  Maryland  corporation  and  an  Interested  Stockholder.
"Interested  Stockholders" are all persons (a)  who beneficially own 10% or more
of the voting power of the corporation's shares or (b) an affiliate or associate
of the corporation who, at any time within the two-year period prior to the date
in question,  was an  Interested Stockholder  or an  affiliate or  an  associate
thereof. Such business combinations are prohibited for five years after the most
recent   date  on  which   the  Interested  Stockholder   became  an  Interested
Stockholder. Thereafter, any  such business combination  must be recommended  by
the  board of directors of such corporation and approved by the affirmative vote
of at least (a) 80% of  the votes entitled to be  cast by all holders of  voting
shares  of the corporation, and (b) 66 2/3%  of the votes entitled to be cast by
all holders of voting shares of the corporation other than voting shares held by
the Interested  Stockholder, or  an  affiliate or  associate of  the  Interested
Stockholder, with whom the business combination is to be effected, unless, among
other things, the corporation's stockholders receive a minimum price (as defined
under  Maryland law) for their shares and  the consideration is received in cash
or in the same  form as previously  paid by the  Interested Stockholder for  its
shares.  These provisions of Maryland law do not apply, unless the corporation's
charter or by-laws provide otherwise, to a corporation that on July 1, 1983  had
an existing Interested Stockholder, unless, at any time thereafter, the Board of
Directors  elects  to be  subject to  the law.  The Company  has adopted  such a
resolution, which has the  effect of making the  law applicable to the  Company,
except  with respect to certain business combinations involving persons who were
Interested Stockholders as of the date of this Prospectus, or their  affiliates,
which  include CEO Venture  Fund II and  George T. Jimenez.  These provisions of
Maryland law  would  not  apply,  however, to  business  combinations  that  are
approved  or exempted by the Board of  Directors of the corporation prior to the
time that any other Interested Stockholder becomes an Interested Stockholder.  A
Maryland  corporation may adopt an  amendment to its charter  electing not to be
subject to the  special voting  requirements of the  foregoing legislation.  Any
such amendment would have to be approved by the affirmative vote of at least 80%
of  the votes entitled to be cast by all holders of outstanding shares of voting
stock and 66 2/3%  of the votes  entitled to be cast  by holders of  outstanding
shares  of voting stock who are not Interested Stockholders. The Company has not
adopted such an amendment to its Charter.
    
 
CONTROL SHARE ACQUISITIONS
 
    Maryland law  provides  that  "control shares"  of  a  Maryland  corporation
acquired  in a "control share  acquisition" have no voting  rights except to the
extent approved by a vote of two-thirds of the votes entitled to be cast on  the
matter,  excluding  shares of  stock owned  by  the acquiror  or by  officers or
directors who are employees of the corporation. Control shares are voting shares
of stock which, if aggregated with all other shares of stock previously acquired
by such  a  person, would  entitle  the acquiror  to  exercise voting  power  in
electing  directors within one of the following  ranges of voting power: (a) 20%
or more but less than 33 1/3%; (b) 33 1/3% or more but less than a majority;  or
(c)  a majority  of all voting  power. Control  shares do not  include shares of
stock an acquiring person is entitled to  vote as a result of having  previously
obtained  stockholder approval.  A control  share acquisition  means, subject to
certain exceptions, the acquisition of, ownership of, or the power to direct the
exercise of voting power with respect to, control shares.
 
    A person who  has made or  proposes to make  a "control share  acquisition,"
upon  satisfaction  of  certain  conditions  (including  an  undertaking  to pay
expenses), may  compel the  board of  directors  to call  a special  meeting  of
stockholders to be held within 50 days of demand therefor to consider the voting
rights  of the shares. If no request for  a meeting is made, the corporation may
itself present the question at any stockholders' meeting.
 
    If voting rights are not approved at the meeting or if the acquiring  person
does  not deliver  an acquiring  person statement  as permitted  by the statute,
then, subject to certain conditions and limitations, the corporation may  redeem
any  or all  of the control  shares (except  those for which  voting rights have
previously been approved) for  fair value determined,  without regard to  voting
rights,  as of the date of the last  control share acquisition or of any meeting
of stockholders at which the voting rights of such shares are considered and not
approved. If voting rights for "control shares" are approved at a  stockholders'
meeting  and the  acquiror becomes  entitled to  vote a  majority of  the shares
 
                                       47
<PAGE>
entitled to vote, all other stockholders may exercise appraisal rights. The fair
value of the stock as determined for  purposes of such appraisal rights may  not
be  less than the highest price per share paid in the control share acquisition,
and certain limitations and restrictions otherwise applicable to the exercise of
dissenters' rights do not apply in the context of a "control share acquisition."
 
    The control share acquisition statute does not apply to stock acquired in  a
merger,  consolidation or stock  exchange if the  corporation is a  party to the
transaction, or to acquisitions previously  approved or exempted by a  provision
in  the  charter  or by-laws  of  the  corporation. The  Company  has  adopted a
provision in  its  Charter exempting  acquisitions  by George  Jimenez  and  his
respective  associates  provided any  such acquisition  does  not cause  them to
acquire more than 49.9% of the outstanding Common Stock in the aggregate.
 
TRANSFER AGENT AND REGISTRAR
 
   
    The transfer  agent and  registrar  for the  Common  Stock is  Chase  Mellon
Shareholder Services.
    
 
                     CERTAIN CHARTER AND BY-LAW PROVISIONS
 
   
    The  Company's Charter and By-laws will be amended as of the closing of this
offering and, as  a result of  such amendment, will  contain several  provisions
that  may make  the acquisition of  control of the  Company by means  of a proxy
fight, open market  purchases, tender  offer, or otherwise  more difficult.  The
following  is a summary of certain of these provisions. The forms of Charter and
By-laws, as amended, are filed as  exhibits to the Registration Statement  filed
with  the  Commission of  which this  Prospectus  is a  part, and  the following
summary is qualified in its entirety by reference to such documents.
    
 
NUMBER OF DIRECTORS
 
    The Charter and By-laws provide that the number of directors shall be  fixed
from  time to time  by resolution adopted by  a majority of  the entire Board of
Directors, but may  not consist of  fewer than  three or such  lesser number  of
stockholders,  nor more than 11 members. The  size of the Board of Directors has
initially been set at five members.
 
CLASSIFIED BOARD OF DIRECTORS
 
    The Charter divides  the Board  of Directors  into three  classes, with  one
class  having a term of one year, one class  having a term of two years, and one
class having a  term of  three years. Each  class is  to be as  nearly equal  in
number  as possible. At each annual meeting of stockholders, commencing with the
annual meeting of stockholders to be held in 1997, directors will be elected  to
succeed  those  directors  whose  terms have  expired,  and  each  newly elected
director will serve for a three-year term.
 
    The classification of directors and the provisions in the Charter that limit
the ability of  stockholders to  increase the size  of the  Board of  Directors,
together  with  the provisions  in the  Charter described  below that  limit the
ability of  stockholders  to remove  directors  and that  permit  the  remaining
directors  to fill any vacancies on the Board, will have the effect of making it
more difficult  for stockholders  to  change the  composition  of the  Board  of
Directors.  As a  result, at  least two annual  meetings of  stockholders may be
required for the stockholders to change a majority of the directors, whether  or
not  a change in the  Board of Directors would be  beneficial to the Company and
its stockholders and  whether or not  a majority of  the Company's  stockholders
believes that such a change would be desirable.
 
REMOVAL OF DIRECTORS AND FILLING VACANCIES
 
    The  Charter  and  By-laws  provide  that  a  director  may  be  removed  by
stockholders only "for cause" and with the approval of the holders of 80% of the
total voting power of all outstanding securities of the Company then entitled to
vote generally in the election of  directors, voting together as a single  class
at a special meeting of stockholders called for that purpose. (Article VI of the
Charter; Section 6).
 
                                       48
<PAGE>
    The  Charter  and  By-laws  provide  that  all  vacancies  on  the  Board of
Directors,  including  those  resulting  from  an  increase  in  the  number  of
directors, may be filled solely by a majority of the remaining directors even if
they  do not  constitute a  quorum. If  the vacancy  occurs as  a result  of the
removal of a director, the stockholders may elect a successor at the meeting  at
which  such removal occurs. If the  entire Board becomes vacant, any stockholder
may call a special meeting in order  to elect directors. (Article II, Section  7
of the By-laws).
 
ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTOR NOMINATIONS
 
   
    The  By-laws establish advance notice  procedures with regard to stockholder
proposals and the nomination, other than by or at the direction of the Board  of
Directors  or  a committee  thereof, of  candidates  for election  as directors.
(Article I,  Sections 11  and 12).  These procedures  require that  a notice  of
stockholder  proposals and stockholder nominations for the election of directors
at any meeting of stockholders must be in writing, containing certain  specified
information  and received by the  Secretary of the Company  not less than 20 nor
more than 30 days prior to the meeting (or if less than 30 days' notice or prior
public disclosure of the date of the meeting is given, the notice of stockholder
proposals or nominations must be in writing and received by the Secretary of the
Company no later than the close of  business on the tenth day following the  day
on which notice of the meeting was mailed or public disclosure thereof was made,
whichever  occurs  first).  The Company  may  reject a  stockholder  proposal or
nomination that is not made in accordance with such procedures.
    
 
LIMITATIONS ON CALLING STOCKHOLDER MEETINGS
 
   
    The Charter and By-laws provide that special meetings of stockholders can be
called only by the Chairman of the Board of Directors, the President, the  Board
of  Directors, or by the Secretary at the  request of holders of at least 25% of
all votes entitled  to be cast.  (Article I,  Section 3 of  the By-laws).  These
provisions  may  have  the effect  of  delaying consideration  of  a stockholder
proposal until the next annual meeting unless a special meeting is called by the
Board of Directors, the Chairman of  the Board, the President, or the  Secretary
of the Company upon the request of holders of a sufficient number of shares.
    
 
AMENDMENT OF CERTAIN PROVISIONS OF THE CHARTER AND BY-LAWS
 
    The Charter of the Company provides that the affirmative vote of the holders
of at least 80% of the aggregate combined voting power of all classes of capital
stock  entitled  to vote  thereon, voting  as  one class,  is required  to amend
certain provisions of the  Charter, including those  provisions relating to  the
number,  election and term of directors; the removal of Directors; the amendment
of the by-laws; the  provision governing applicability  of the Maryland  Control
Share  Act  (Section 3-702  of the  Maryland General  Corporation Law);  and the
supermajority voting requirements in the Charter. (Article VII, Section 1).  The
Charter  further provides that Board of Directors shall have the exclusive right
to make, alter,  amend or repeal  the By-laws. (Article  VII, Section 5).  These
requirements  will have  the effect  of making  more difficult  any amendment by
stockholders, even if a majority of the Company's stockholders believe that such
amendment would be in their best interests.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this offering, there has been no market for the Common Stock of the
Company. Sales  of substantial  shares  of Common  Stock  in the  public  market
following  this offering, or  the perception that such  sales could occur, could
adversely affect the market  price of the Common  Stock prevailing from time  to
time  and could impair the Company's future  ability to raise capital through an
offering of its  equity securities.  See "Risk  Factors --  Shares Eligible  for
Future Sale."
 
   
    Upon  completion  of  this  offering, the  Company  will  have approximately
7,391,401 shares  of  Common Stock  outstanding  (assuming no  exercise  of  the
Underwriters' over-allotment option.) Of these shares, the 2,500,000 shares sold
in this offering will be freely transferable without restriction or registration
under  the  Securities  Act, except  for  any  shares purchased  by  an existing
"affiliate" of the Company, as that term is defined under the Securities Act (an
"Affiliate"), which shares will be subject to the resale limitations of Rule 144
adopted under the Securities Act. The remaining 4,891,401
    
 
                                       49
<PAGE>
   
outstanding shares of Common Stock which  were issued by the Company in  private
transactions  not involving  a public offering  (and any shares  issued upon the
exercise of stock options granted pursuant  to the Stock Plan and the  Directors
Stock Plan), are "restricted securities" for purposes of Rule 144 and may not be
resold  in a  public distribution,  except in  compliance with  the registration
requirements  of  the  Securities  Act,  pursuant  to  a  valid  exemption  from
registration  or pursuant to Rule 144. Of such shares, and without consideration
of the  contractual  restrictions  described  below,  290,955  shares  would  be
available  for immediate sale in the  public market without restriction pursuant
to Rule 144(k) and 4,293,739 additional shares would be available for  immediate
sale  subject to compliance with the restrictions of Rule 144. Beginning 90 days
after the date of this Prospectus, and without consideration of the  contractual
restrictions  described below, 213,998  additional shares would  be eligible for
sale without restrictions in reliance upon Rule 701 promulgated under Securities
Act and  92,709  additional  shares  would  be  eligible  for  sale  subject  to
compliance with the restrictions of Rule 144.
    
 
   
    The  holders of 4,748,211 shares of Common Stock in the aggregate, including
each officer  and director  of the  Company and  the Selling  Stockholder,  have
agreed  not to offer, pledge,  sell, offer to sell,  contract to sell, grant any
option to purchase, or otherwise transfer or dispose of, directly or indirectly,
any shares of Common Stock or any securities exercisable or exchangeable for, or
convertible into, shares of Common Stock for a period of 180 days after the date
of this Prospectus,  without the prior  written consent of  Furman Selz LLC,  on
behalf  of the Underwriters. Furman Selz LLC  may, in its sole discretion and at
any time without notice, waive the lock-up  restrictions as to all or a  portion
of  the securities subject to lock-up  agreements. Furman Selz LLC currently has
no  plans  to  grant  any  such  waivers.  As  a  result  of  these  contractual
restrictions  and the  provisions of Rules  144(k), 144 and  701, the restricted
shares will be available for  sale in the public  market as follows: (i)  89,189
shares  will be eligible for immediate sale on the date of this Prospectus, (ii)
54,001 shares  will  be  eligible for  sale  90  days after  the  date  of  this
Prospectus  and (iii) 4,748,211 shares will be  eligible for sale 180 days after
the date of this Prospectus upon expiration of lock-up agreements.
    
 
   
    In general, under Rule 144 as  currently in effect, beginning 90 days  after
the  date of this Prospectus, a person  (or persons whose shares are aggregated)
who has  beneficially  owned  restricted  securities  for  at  least  two  years
(including  the holding  period of  any prior owner  except an  affiliate of the
Company) would be  entitled to sell  within any three-month  period a number  of
shares  that does not  exceed the greater of:  (i) one percent  of the number of
shares of Common Stock then  outstanding (which will equal approximately  73,914
shares  immediately after  this offering);  or (ii)  the average  weekly trading
volume of the Common Stock during  the four calendar weeks preceding such  sale,
subject  to the filing of a Form 144 with respect to such sale. Sales under Rule
144  are  also  subject  to  certain  manner  of  sale  provisions  and   notice
requirements  and to  the availability of  current public  information about the
Company. Under Rule 144(k), a person who is not deemed to have been an Affiliate
at any  time during  the  90 days  immediately preceding  a  sale, and  who  has
beneficially  owned the  shares proposed  to be  sold for  at least  three years
(including the  holding period  of  any prior  owner  except an  Affiliate),  is
entitled  to sell such shares without complying  with the manner of sale, public
information, volume limitation or notice provisions of Rule 144. Subject to  the
contractual  restrictions described above, "144(k) shares" may therefore be sold
immediately  upon  the  completion  of  this  offering.  Persons  deemed  to  be
Affiliates  must always  sell pursuant  to Rule  144, even  after the applicable
holding periods have been satisfied.
    
 
    The Commission  has recently  proposed  amendments to  Rule 144  that  would
permit resales of restricted securities after a one-year, rather than a two-year
holding period, subject to compliance with the other provisions of Rule 144, and
would permit resale of restricted securities by non-Affiliates under Rule 144(k)
after  a two-year,  rather than  a three-year  holding period.  If adopted, such
amendments could result in resales of restricted securities sooner than would be
the case under Rule 144 as currently in effect.
 
    Subject to  certain  limitations  on  the  aggregate  offering  price  of  a
transaction  and other conditions, Rule  701 may be relied  upon with respect to
the resale of securities originally purchased from
 
                                       50
<PAGE>
the Company by its employees, directors, officers, consultants or advisors prior
to the date  the issuer  becomes subject to  the reporting  requirements of  the
Exchange Act pursuant to written compensatory benefit plans or written contracts
relating  to the compensation  of such persons. In  addition, the Commission has
indicated that Rule 701 will apply to typical stock options granted by an issuer
before it becomes  subject to the  reporting requirements of  the Exchange  Act,
along  with  the  shares  acquired  upon  exercise  of  such  options (including
exercises after the date of this  Prospectus). Securities issued in reliance  on
Rule  701 are restricted securities and, subject to the contractual restrictions
described above, beginning  90 days after  the date of  this Prospectus, may  be
sold  by  persons other  than  Affiliates subject  only  to the  manner  of sale
provisions of Rule 144 and by Affiliates under Rule 144 without compliance  with
its two-year minimum holding period requirements.
 
   
    At  June 30, 1996, options to purchase 1,073,704 shares of Common Stock were
outstanding, of which options to purchase approximately 938,704 shares were then
vested and exercisable. Shortly after this offering, the Company intends to file
registration statements on Form S-8 under the Securities Act covering shares  of
Common  Stock  reserved  for  issuance  under  the  Company's  stock  plans. See
"Management -- Amended and Restated Omnibus Stock Plan." Shares of Common  Stock
issued  upon exercise of  options under the registration  statements on Form S-8
will be available for sale in the  public market, subject to Rule 144 manner  of
sale  and  volume limitations  in  the case  of  Affiliates and  subject  to the
contractual restrictions described above. Beginning  180 days after the date  of
this  Prospectus,  approximately 681,373  shares issuable  upon the  exercise of
vested stock options will become eligible for sale in the public market, if such
options are exercised.
    
 
REGISTRATION RIGHTS
 
   
    After this offering, the  holders of 1,300,950 shares  of Common Stock  (the
"Registrable Securities") will be entitled to certain rights with respect to the
registration  of such shares  under the Securities  Act. Under the  terms of the
agreement between the Company and the holders of such Registrable Securities, if
the Company proposes to register any of its securities under the Securities Act,

such registration.  Further,  the  holders of  the  Registrable  Securities  may
require  the Company to file additional registration statements on Form S-3. All
of these registration rights are subject to certain conditions and  limitations,
among  them the right of the underwriters of  an offering to limit the number of
shares included in such registration.

    The Underwriting Agreement provides that the obligations of the Underwriters
to purchase the shares of Common Stock listed above are subject to the  approval
of   certain  legal  matters  by  counsel  and  various  other  conditions.  The
Underwriting Agreement  also provides  that the  Underwriters are  committed  to
purchase  all of the shares of Common Stock offered hereby, if any are purchased
(without  consideration  of  any  shares  that  may  be  purchased  through  the
Underwriters' over-allotment option).
 
    The  Representatives have  advised the  Company and  the Selling Stockholder
that the Underwriters propose to offer the shares of Common Stock to the  public
initially at the public offering price set forth on the cover of this Prospectus
and  to certain dealers at such price less a concession not in excess of $
per share. The Underwriters may allow, and such selected dealers may reallow,  a
concession not in excess of $      per share to certain other dealers. After the
initial  public  offering of  the shares,  the public  offering price  and other
selling terms may be changed by the Representatives.
 
    Prior to the offering made hereby, there  has been no public market for  the
Common  Stock. Accordingly,  the initial  public offering  price for  the Common
Stock  will  be  determined  by  negotiation  among  the  Company,  the  Selling
Stockholder  and the Representatives. Among the factors to be considered are the
Company's results of  operations and current  financial condition, estimates  of
the  business  potential  and  prospects  of the  Company,  the  market  for the
Company's products, the experience of the Company's management, the economics of
the industry in general, the general condition of the equities market and  other
relevant  factors. There can be no assurance that any active trading market will
develop for the Common Stock  or as to the price  at which the Common Stock  may
trade  in the public  market from time  to time subsequent  to the offering made
hereby.
 
   
    The Company has granted the  Underwriters an option, exercisable during  the
30-day  period after  the date  of this  Prospectus, to  purchase up  to 375,000
additional shares of Common Stock at the public offering price set forth on  the
cover  page of this Prospectus, less  underwriting discounts and commissions. To
the extent the Underwriters exercise this  option, each Underwriter will have  a
firm  commitment,  subject to  certain conditions,  to  purchase such  number of
additional shares  of Common  Stock as  is proportionate  to such  Underwriter's
initial  commitment to  purchase shares from  the Company.  The Underwriters may
exercise such  option  solely to  cover  over-allotments, if  any,  incurred  in
connection with the sale of shares of Common Stock offered hereby.

otherwise transfer or dispose of, directly  or indirectly, any shares of  Common
Stock or securities exchangeable or exercisable for, or convertible into, shares
of Common Stock (other than, in the case of the Company, the granting of options
pursuant  to the Stock  Plan and the Directors  Stock Plan) for  a period of 180
days from the  date of  the Underwriting  Agreement, without  the prior  written
consent of Furman Selz LLC, on behalf of the Underwriters.

                                      objective.
Asynchronous Transfer Mode
(ATM)...............................  A  recently commercialized switching and transmission
                                      technology that is one of  a general class of  packet
                                      technologies  that relay traffic by way of an address
                                      contained within the  first five bits  of a  standard
                                      fifty-three bit-long packet or cell. ATM-based packet
                                      transport   was   specifically  developed   to  allow
                                      switching and transmission of  mixed voice, data  and
                                      video   (sometimes   referred  to   as  "multi-media"
                                      information) at varying rates. The ATM format can  be
                                      used by many different information systems, including
                                      LANs.
Bandwidth...........................  The  range of  frequencies or  bit rates  that can be
                                      transmitted   by   a   communications   channel,    a
                                      transmission facility or a transmission medium.
Broadband...........................  Broadband  communications systems  can transmit large
                                      quantities of voice, data and video by way of digital
                                      or   analog    signals.   Examples    of    broadband
                                      communication   systems  include   DS-3  fiber  optic
                                      systems, which  can transmit  672 simultaneous  voice
                                      conversations,  or  a  broadcast  television  station
                                      signal, that  transmits  high  resolution  audio  and
                                      video  signals into the  home. Broadband connectivity
                                      is  also   an  essential   element  for   interactive
                                      multimedia applications.
Carrier.............................  In   the   telecommunications   industry,   one  that
                                      "carries"   transmission   capabilities   over    the
                                      telecommunications  network.  A  carrier  that offers
                                      telecommunications services to the public is  subject
                                      to   regulation  by  federal   and  state  regulatory
                                      commissions.
Central Office......................  The switching centers or central switching facilities
                                      of the local telephone companies.
CENTREX.............................  CENTREX is a service that offers features similar  to
                                      those  of a Private Branch Exchange (PBX), except the
                                      equipment is located  at the  carrier's premises  and
                                      not  at the premises of  the customer. These features
                                      include direct dialing within  a given phone  system,
                                      direct  dialing  of  incoming  calls,  and  automatic
                                      identification of outbound calls.  This is a  service
                                      that  local telephone companies can provide to a wide
                                      range of customers who  do not have  the size or  the
                                      funds to support their own on-site PBX.
Client..............................  The client component of a client server system. It is
                                      typically  a personal computer  with a graphical user
                                      interface.
Client Server Architecture..........  A  computer   system   architecture  in   which   two
                                      independent  processes communicate via an established
                                      protocol. The

                                      client  component  makes   requests  to  the   server
                                      component,   which   responds  with   information  or
                                      actions.  The  client  component  is  typically   the
                                      "front-end"  of the system and is operated by the end
                                      user.
Digital.............................  A method  of  storing,  processing  and  transmitting
                                      information through the use of distinct electronic or
                                      optical  pulses that represent the binary code digits
                                      0  and   1.   Digital  transmission   and   switching
                                      technologies  employ  a sequence  of these  pulses to
                                      represent information as opposed to the  continuously
                                      variable  analog  signal.  Digital  transmission  and
                                      switching technologies offer a threefold  improvement
                                      in   speed  and  capacity   over  analog  techniques,
                                      allowing  much  more  efficient  and   cost-effective
                                      transmission of voice, video and data.
Fiberoptic..........................  A  technology  in which  light  is used  to transport
                                      information from  one  point  to  another.  Fiber  is
                                      immune  to electrical  interference and environmental
                                      factors  that  affect  copper  wiring  and  satellite
                                      transmission.
Frame Relay.........................  Frame  relay is  a high  speed data  packet switching
                                      service used  to  transmit  data  between  computers.
                                      Frame  relay supports data  units of variable lengths
                                      at access  speeds ranging  from  56 kilobits  to  1.5
                                      megabits.  This service is appropriate for connecting
                                      LANs, but  is not  appropriate  for voice  and  video
                                      applications  due  to the  variable delays  which can
                                      occur. Frame relay  was designed to  operate at  high
                                      speed on modern fiber optic networks.
Graphical User Interface............  A   means  of   communicating  with   a  computer  by
                                      manipulating graphical icons and windows (usually  by
                                      pointing and clicking a mouse) rather than using text
                                      commands.
Hybrid Fiber Coaxial................  A  telecommunications network composed  of both fiber
                                      and coaxial cable,  typically used  to deliver  video
                                      and/or voice services to residences.
ISO.................................  International Standards Organization. An
                                      international  standards group that is concerned with
                                      defining standards for data communication and network
                                      management.   Committees    throughout   the    world
                                      contribute to the ISO standards set forth.
Internet............................  The  global  system  of  networks  interconnected  by
                                      TCP/IP (and IP-related protocols), which include over
                                      30 million users from the private sector, educational
                                      institutions, government, nonprofits, and
                                      individuals. Internet  users gain  access to  e-mail,
                                      file  transfer,  remote log-in,  gopher,  news, World

                                      the requirements of said procurement. The RFP is then
                                      distributed  to all prospective  vendors, so they may
                                      respond in detail to  the requirements and provide  a
                                      quotation  for the project as defined within the RFP.
                                      The goal of the RFP process is to procure the item(s)
                                      that are detailed within the RFP.
Server..............................  Software that allows a computer to offer a service to
                                      another computer. Other computers contact the  server
                                      program  by  means  of matching  client  software. In
                                      addition, such  term  means  the  computer  on  which
                                      server software runs.

Simple Network Management Protocol
(SNMP)..............................  A   standard   protocol   that   gathers   management
                                      information from network devices and provides a means
                                      to set and monitor configuration parameters.
Switch..............................  A computer that accepts instructions from a caller in
                                      the form of a telephone number. Like an address on an
                                      envelope, the numbers tell the switch where to  route
                                      the  call.  The switch  opens  or closes  circuits or
                                      selects  the  paths  or  circuits  to  be  used   for
                                      transmission  of information. Switching  is a process
                                      of interconnecting  circuits to  form a  transmission
                                      path  between users. Switches allow local carriers to
                                      connect calls  directly to  their destination,  while
                                      providing  advanced features and recording connection
                                      information for future billing.
Transmission Control
Protocol/Internet Protocol
(TCP/IP)............................  A  compilation   of  network-   and   transport-level
                                      protocols   that  allows   computers  with  different
                                      architectures  and  operating   system  software   to
                                      communicate with other computers on the Internet.
World Wide Web......................  A  network of  computer servers  that uses  a special
                                      communications protocol  to  link  different  servers
                                      throughout  the Internet and permits communication of
                                      graphics, video and sound.
X.25................................  A protocol  that  defines the  connection  between  a
                                      terminal  and the public packet-switching network for

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
   
To the Board of Directors and Stockholders of
  ACE*COMM Corporation
    
 
   
The  recapitalization described in  Note 11 to the  financial statements has not
been consummated as of July  17, 1996. When it is  consummated, we will be in  a
position to furnish the following report:
    
 
   
    "In  our opinion, the accompanying balance sheets and the related statements
    of operations,  of changes  in stockholders'  equity (deficit)  and of  cash
    flows  present fairly, in  all material respects,  the financial position of
    ACE*COMM Corporation  at June  30, 1995  and 1996,  and the  results of  its
    operations  and its  cash flows for  each of  the three years  in the period
    ended June  30,  1996,  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."

                         NOTES TO FINANCIAL STATEMENTS
    
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    ORGANIZATION
 
   
    ACE*COMM  Corporation ("ACE*COMM"  or the  "Company") develops,  markets and
services operations support  systems ("OSS") products  for networks deployed  by
telecommunications  service providers, such as telephone companies, other public
carriers 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 for
some of the largest carriers and enterprises in the world.
    
 
   
    USE OF ESTIMATES
    
 
   
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions that effect the amounts reported in the financial statements. Actual
results could differ from those estimates.
    
 
    PRO FORMA STOCKHOLDERS' EQUITY (UNAUDITED)
 
   
    If the offering  contemplated by  this Prospectus is  consummated under  the
terms presently anticipated, all of the Mandatorily Redeemable Class C Preferred
Stock  (the "Class C Preferred  Stock") will convert to  shares of the Company's
Common Stock (the "Common Stock"). Pro forma stockholders' equity as of June 30,
1996, is adjusted  for the  conversion of Class  C Preferred  Stock into  Common
Stock.
    
 
   
    REVENUE RECOGNITION
    
 
   
    The   Company  recognizes  revenue  principally  under  long-term  contracts
involving significant production, modification or customization of hardware  and
software   using  the  percentage-of-completion  method,  based  on  performance
milestones specified  in  the contract,  which  fairly reflect  progress  toward
contract completion.
    
 
   
    Revenue from maintenance and other postcontract customer support services is
recognized ratably over the term of the related agreements.
    
 
    SIGNIFICANT CUSTOMERS
 
   
    The  Company  extends  credit  to  its customers  in  the  normal  course of
business.  Three  customers  in  the  telecommunications  industry   represented
approximately  57%,  59%  and  51%  of  revenues  during  1994,  1995  and 1996,
respectively. International customers represented approximately 37%, 63% and 69%
of revenues during 1994, 1995 and 1996, respectively.
    
 
    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 and until 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.
 
    INVENTORIES
 
    Inventories, which consists 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.

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    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, fixtures  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.
 
    INCOME TAXES
 
    Effective  July  1,  1993,  the  Company  adopted  Statement  of   Financial
Accounting  Standards  No. 109  (SFAS No.  109)  "Accounting for  Income Taxes."
Previously, the Company used the deferred method for computing income taxes. The
adoption of  SFAS No.  109  did not  have a  material  impact on  the  Company's
financial position or results of operations.
 
    Income  taxes are provided  for the tax effects  of transactions reported in
the financial statements and consist of taxes currently due plus deferred  taxes
related  primarily  to differences  between the  basis  of fixed  and intangible
assets and  revenue recognition  for  financial and  income tax  reporting.  The
deferred  tax assets  and liabilities represent  the future  tax consequences of
those differences, which will  either be taxable or  deductible when the  assets
and liabilities are recovered or settled.
 
   
    FAIR VALUE OF FINANCIAL INSTRUMENTS
    
 
   
    The  carrying amounts  of cash,  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.
    
 
   
    The  Company believes  that it  is not practical  to estimate  a fair market
value different from the Class C Preferred Stock carrying value of $2,261,627 as
the security  has  numerous unique  features  including voting,  redemption  and
conversion rights and is not traded on an open market.
    
 
   
    PRO FORMA NET INCOME PER SHARE
    
 
   
    Historical  net (loss)  income per  share is  not considered  relevant as it
would  differ  materially  from  pro  forma  net  income  per  share  given  the
contemplated  changes in the  capital structure of the  Company. Except as noted
below, pro forma  net income per  share is computed  using the weighted  average
number  of  shares of  Common Stock,  assuming conversion  of Class  C Preferred
Stock, and dilutive Common  Stock equivalent shares  from Common Stock  options.
Common  Stock equivalent shares are calculated  using the treasury stock method.
Pursuant to Securities and Exchange Commission Staff Accounting Bulletin No. 83,
Common Stock and Common Stock equivalent shares issued by the Company at  prices
below  the public  offering price  during the twelve  month period  prior to the
proposed offering date (using the treasury stock method and an offering price of
$10 per share) have been included in the calculation as if they were outstanding
for all of 1996 regardless of whether they are dilutive.

5.  BORROWINGS (CONTINUED)
   
    Effective May 29, 1996,  the Company entered into  new loan agreements  with
its  bank. The Company's $2,500,000 line of  credit was extended to November 30,
1997. The new line bears interest payable monthly, at 0.5% over the bank's prime
rate and  the  principal  is  due  November 30,  1997.  In  addition,  a  second
$1,350,000  line  of credit  was replaced  with  a revolving  line of  credit of
$1,000,000. This facility  bears interest at  0.5% over the  bank's prime  rate,
payable monthly, and the principal is due on November 30, 1997. These new credit
facilities and installment notes with the same financial institution are secured
by  accounts receivable and  inventory certain of which  are subordinated to the
security interests of the  credit agreement described  below, and the  agreement
contains certain financial covenants.
    
 
   
    Effective  March 1, 1996, the Company entered into a credit agreement with a
bank to finance inventory for a foreign  contract. The Company can borrow up  to
$1,000,000  at  1.25% over  the bank's  prime rate.  The agreement  requires the
Company to comply with  certain financial covenants. On  behalf of the  Company,
the  U.S.  Export-Import Bank  guarantees  to the  bank  90% of  the outstanding
balance, which is collateralized  by the inventory  and the foreign  receivables
generated by the contract. This agreement expires on August 31, 1996.
    
 
6.  TRANSACTIONS WITH RELATED PARTIES
   
    In  connection with  the purchase  of certain assets  by the  Company at its
inception, the Company's president loaned $150,000  to the Company to assist  in
financing  the acquisition.  The note bears  interest at  the Federal short-term
rate established periodically  by the U.S.  Treasury (5.12% at  June 30,  1996).
Principal  and interest is paid quarterly.  The outstanding loan balance totaled
$95,833 and $78,572 at June 30, 1995 and 1996, respectively.
    
 
   
    During 1994,  1995  and 1996,  the  Company purchased  inventories  totaling
approximately  $1,036,000, $62,000  and $212,000,  respectively, from  a company
whose Board of Directors included the Company's president and another member  of
the Company's Board of Directors. The Company's president retired from the other
company's  Board of Directors in January 1994. Accounts payable at June 30, 1995
and 1996  include approximately  $125,000 and  $32,000, respectively,  which  is
payable to this company.
    
 
7.  RETIREMENT PLAN
   
    The   Company  has  a  simplified-employee   pension  plan  (SEPP)  covering
substantially all employees. Under the SEPP, the Company makes contributions  to
the  plan subject to Company performance  and the maximum contribution allowable
by the  IRS.  The  contribution  rate  is set  annually  at  the  discretion  of
management.  Contributions made during  1994, 1995 and  1996, were approximately
$120,300, $0 and $0, respectively.
    
 
   
    On April 1,  1994, the Company  established a 401(k)  plan. 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. Contributions made during 1994,
1995 and 1996 were approximately $0, $0 and $97,000, respectively.

    At June 30, 1995 and 1996, a  valuation allowance was recorded for the  full
value  of net  deferred tax  assets as realization  of these  benefits cannot be
reasonably assured.
    
 
   
    In 1994, the provision for income taxes was comprised of a Federal and state
provision of  $258,000,  which  was  offset by  a  reduction  in  the  valuation
allowance  of the same amount. The change during 1995 in the valuation allowance
was largely attributable to the increase  in net operating losses. In 1996,  the
provision  for income taxes  was comprised of  a Federal and  state provision of
$457,000, which was offset by a reduction in the valuation allowance of the same
amount. In addition, the Company recorded a foreign tax credit of $44,000, which
increased the valuation allowance.
    
 
   
    At June 30, 1996, the Company has available research credit carryforwards of
approximately $292,000  which are  available  to offset  future income  tax  and
expire  in  years  through  2007.  The  Company  also  has  net  operating  loss
carryforwards for income tax purposes  of approximately $2,410,000 which  expire
in  years through  2010. Ownership changes,  as defined in  the Internal Revenue
Code, may  limit the  amount of  net operating  loss carryforwards  that can  be
utilized annually to offset future taxable income or tax liability.

9.  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)
provides  voting rights equal to  the same number of  shares of Common Stock and
Series 2 stock (128,484 shares) provides no  voting rights but, if elected by  a
majority  of the  holders of  the Class  C Preferred  Stock, will  become voting
shares on a one-to-one basis.
    
 
   
    Each share of Class C Preferred Stock may be converted into Common Stock  at
any time by the holder. Additionally, the shares will be converted automatically
upon  an underwritten, public offering of the Common Stock. The number of shares
of Common Stock  into which  the Class  C Preferred  Stock can  be converted  is
determined by a conversion price, as defined under the agreement. Currently, the
conversion  price is $1.14 per  share and if converted  now, the shares would be
exchanged on a  4.5 to 1  basis. No dividends  are payable with  respect to  any
converted  shares. The Company has reserved 1,530,950 shares of Common Stock for
the purpose of conversion.
    
 
   
    Any shares not converted by designated dates will be redeemed 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  is  equal to  $5.14 per  share  plus
accrued  dividends.  In the  case  of redemption,  the  holders are  entitled to
receive accrued dividends, at a semi-annual rate of four percent, from  November
1,  1992.  The  Company also  has  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. As of
June 30, 1996, the Company had no right to force redemption. The holders of  the
securities postponed the September 15, 1995 redemption until September 15, 1996.
    
 
   
    Activity with respect to Class C Preferred Stock is as follows:

10. STOCKHOLDERS' EQUITY
   
    All  shares of Common  Stock are subject to  restriction upon resale. Shares
may only be  offered to the  Company for sale,  and upon termination,  employees
holding  shares of Common Stock are subject to the Company's right or obligation
to repurchase all such shares at a price based on the stock purchase  agreement.
As of June 30, 1996, the Company had no obligation to repurchase any shares held
by employees.
    
 
    The  Class B preferred stock  contains no voting rights,  bears no rights to
receive dividends,  is nonconvertible,  and is  redeemable for  $308,000 at  the
option  of the Company, or  must be redeemed upon  transfer of substantially all
assets or of majority control of the Company.
 
    STOCK OPTIONS
 
   
    Prior to the establishment of the Company's formal option plan, the  Company
granted  options  to various  employees for  performance and  hiring incentives.
Under this plan,  909,000 options  were granted  and 886,500  were exercised  or
expired  prior to  1994 with an  option price of  $.17 - $.62.  During 1995, the
remaining 22,400 shares were exercised at a price of $.17. The Company no longer
issues options under this plan.
    
 
   
    The Company has reserved 2,200,000 shares of Common Stock in connection with
a Board  of Directors  approved  plan to  grant  nonqualified stock  options  to
officers and key employees and 200,000 shares of Common Stock in connection with
a  plan  to  grant  nonqualified  stock  options  to  the  Company's nonemployee
directors. The exercise price on all  options granted is equivalent to the  fair
market  value of  the Company's Common  Stock on  the date of  grant. Vesting of
employee options is determined by the Board of Directors and options vest either
immediately or over a one to two year period. Options expire upon the earlier of
the employee's termination or 3 to 5  years from the date of grant. Options  for
directors  vest 1,000  shares each year  from the  date of grant  and expire the
earlier of 5 years from date of grant, 6 months upon resignation or  immediately
upon  removal  for  cause. The  Company  had exercisable  options  of 1,131,193,
1,187,407, and 938,704  as of June  30, 1994, 1995  and 1996, respectively.  The
stock  option plan  also provides  for the  issuance of  restricted stock, stock
appreciation rights and  phantom stock options.  As of June  30, 1994, 1995  and
1996,  no restricted stock,  stock appreciation rights  or phantom stock options
had been  granted. As  of June  30, 1996,  options available  for granting  were
478,372.

11. RECAPITALIZATION
   
    On July 17, 1996, the Board of Directors approved a 4.5-for-one stock split,
to  be  effected  in  the  form  of  a  stock  dividend  to  be  distributed  on

and market  prices of  the  Common Stock  have  been retroactively  restated  to
reflect the increased number of shares of Common Stock outstanding.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    (a) Section  2-418  of the  Corporations  and Associations  Article  of  the
Annotated  Code of Maryland  permits a corporation to  indemnify its present and
former directors, among others, against judgments, penalties, fines, settlements
and reasonable  expenses  actually  incurred  by them  in  connection  with  any
proceeding  to which  they may be  made a party  by reason of  their services in
those or other capacities, unless it is established that (a) the act or omission
of the  director or  officer was  material to  the matter  giving rise  to  such
proceeding  and (i) was committed in bad faith  or (ii) was the result of active
and deliberate dishonesty; or (b) the  director or officer actually received  an
improper personal benefit in money, property, or services; or (c) in the case of
any criminal proceeding, the director or officer had reasonable cause to believe
that  the act or  omission was unlawful.  Maryland law permits  a corporation to
indemnify a present and former officer to the same extent as a director, and  to
provide  additional indemnification to an officer who is not also a director. In
addition, Section 2-418(f) of the  Corporations and Associations Article of  the
Annotated Code of Maryland permits a corporation to pay or reimburse, in advance
of  the  final  disposition  of  a  proceeding,  reasonable  expenses (including
attorney's fees) incurred  by a  present or former  director or  officer made  a
party to the proceeding by reason of his service in that capacity, provided that
the corporation shall have received (a) a written affirmation by the director or
officer  of  his good  faith  belief that  he has  met  the standard  of conduct
necessary for indemnification by the corporation; and (b) a written  undertaking
by or on his behalf to repay the amount paid or reimbursed by the corporation if
it shall ultimately be determined that the standard of conduct was not met.
 
    The  Registrant  has provided  for  indemnification of  directors, officers,
employees, and agents in Article VIII of its charter, as amended. This provision
reads as follows:
 
        Section 1.  Mandatory Indemnification.
 
        The Corporation shall indemnify its currently acting and its  former
    directors  and  officers against  any and  all liabilities  and expenses
    incurred in connection  with their  services in such  capacities to  the
    maximum  extent permitted  by the  Maryland General  Corporation Law, as
    from time to time amended.
 
        Section 2.  Discretionary Indemnification.
 
                                      II-1
<PAGE>
        If approved by the Board of Directors, the Corporation may indemnify
    its employees, agents  and persons  who serve  and have  served, at  its
    request  as a director, officer, partner,  trustee, employee or agent of
    another corporation, partnership, joint  venture or other enterprise  or
    employee  benefit plan to the extent determined to be appropriate by the
    Board of Directors.
 
        Section 3.  Advancing Expenses Prior to a Decision.
 
        The Corporation shall advance expenses to its directors and officers
    entitled to mandatory indemnification to the maximum extent permitted by
    the Maryland General Corporation Law, as from time to time amended,  and
    may  in the  discretion of  the Board  of Directors  advance expenses to
    employees, agents and others who may be granted indemnification.
 
        Section 4.  Other Provisions for Indemnification.
 
        The Board of Directors may, by bylaw, resolution or agreement,  make
    further  provision for indemnification of directors, officers, employees
    and agents.
 
    Insofar as indemnification for liabilities arising under the Securities  Act
of  1933 may be permitted to directors,  officers and controlling persons of the
registrant pursuant to  the foregoing provisions,  or otherwise, the  registrant
has  been advised that in the opinion  of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for  indemnification
against  such liabilities (other than the  payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the  registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled  by controlling  precedent, submit  to a  court of  appropriate
jurisdiction  the  question of  whether such  indemnification  by it  is against
public policy as expressed  in the Securities  Act and will  be governed by  the
final adjudication of such issue.
 
    Under  Maryland law, a corporation is permitted to limit by provision in its
charter the liability of directors and officers, so that no director or  officer
of  the corporation shall be liable to the corporation or to any stockholder for
money damages except  to the extent  that (i) the  director or officer  actually
received  an improper benefit in money, property, or services, for the amount of
the benefit or profit in money, property or services actually received, or  (ii)
a  judgment or other  final adjudication adverse  to the director  or officer is
entered in a proceeding based on a finding in the proceeding that the director's
or officer's action, or failure to act, was the result or active and  deliberate
dishonesty  and  was  material  to  the  cause  of  action  adjudicated  in  the
proceeding.
 
    The Registrant has limited the liability  of its directors and officers  for
money  damages in Article VIII of its  charter, as amended. This provision reads
as follows:
 
    Section 5.  Limitation of Liability of Directors and Officers.
 
    To the fullest  extent that limitations  on the liability  of directors  and
officers  are permitted by the Maryland  General Corporation Law, no director or
officer of  the  Company  shall  have  any  liability  to  the  Company  or  its
stockholders  for  damages.  This  limitation  on  liability  applies  to events
occurring at the time a person serves  as a director or officer of the  Company,
whether  or not such person is serving as  such at the time of any proceeding in
which liability is asserted.

ITEM 17.  UNDERTAKINGS.
 
    Insofar  as indemnification for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
Registrant pursuant to the provisions contained in the Articles of Amendment and
Restatement  of  the  Registrant and  the  laws  of the  State  of  Maryland, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange  Commission  such  indemnification  is  against  public  policy  as
expressed  in the Securities Act and  is, therefore, unenforceable. In the event
that a  claim  for indemnification  against  such liabilities  (other  than  the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling  person of the  Registrant in the successful  defense of any action,
suit or proceeding) is asserted by such
 
                                      II-4

director, officer or controlling person in connection with the securities  being
registered, the Registrant will, unless in the opinion of its counsel the matter
has  been settled  by controlling  precedent, submit  to a  court of appropriate
jurisdiction the question whether such  indemnification by it is against  public
policy  as expressed  in the Securities  Act and  will be governed  by the final
adjudication of such issue.
 
    The undersigned registrant hereby undertakes to provide to the  Underwriters
at  the closing  specified in the  Underwriting Agreement,  certificates in such
denominations and registered in  such names as required  by the Underwriters  to
permit prompt delivery to each purchaser.
 
    The undersigned registrant hereby undertakes that:
 
    (1)  For purposes of determining any liability under the Securities Act, the
information  omitted  from  the  form  of  prospectus  filed  as  part  of  this
Registration  Statement in reliance  upon Rule 430A  and contained in  a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4), or  497(h)
under  the Securities  Act shall  be deemed  to be  a part  of this Registration
Statement as of the time it was declared to be effective.
 
    (2) For the purpose of determining  any liability under the Securities  Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to  be a new registration statement  relating to the securities offered therein,
and the offering  of such  securities at  that time shall  be deemed  to be  the
initial bona fide offering thereof.

     (1)  The Board of Directors o the Corporation is hereby empowered to

respects, from time to time before issuance of such shares, the preferences, 
rights, voting powers, restrictions and qualifications of, the dividends on,

     The enumeration and definition of a particular power of the Board of 
Directors included in the foregoing shall in no way be limited or restricted 
by reference to or inference from the terms of any other clause of this or

deemed by inference or otherwise in any manner to exclude or limit any powers 
conferred upon the Board of Directors under the Public General Laws of the 
State of Maryland now or hereafter in force.

     EIGHTH:  Except as may otherwise be provided by the Board of Directors 
of the Corporation, no holder of any shares of the stock of the Corporation 
shall have any pre-emptive right to purchase, subscribe for, or otherwise 
acquire any shares of stock of the Corporation of any class now or hereafter 
authorized, or any securities exchangeable for or convertible into such 
shares, or any warrants or other instruments evidencing rights or options to 
subscribe for, purchase or otherwise acquire such shares.

     NINTH:

     (1)  REQUIRED INDEMNIFICATION.  The Corporation shall provide 
indemnification to directors, officers, employees and agents to the extent 
required by applicable provisions of the Public General Laws of the State of 
Maryland.

     (2)  PERMITTED INDEMNIFICATION.  The Corporation may indemnify any 
director, officer, employee or agent, made a party to any threatened, pending 
or completed action or proceeding whether civil, criminal, administrative or 
investigative if authorized in the specific case as set forth in paragraph 
(3) below, and if he acted in good faith and reasonably believed (i) in the 
case of conduct in his official capacity, the conduct was in the best 
interests of the Corporation, (ii) in the case of conduct not in his official 
capacity, that the conduct was at least not opposed to the best interests of 
the Corporation or (iii) in the case of any criminal proceeding, that he had 
no reasonable cause to believe that the conduct was unlawful.

     Indemnification under this Article may be against judgments, penalties, 
fines, settlements, and reasonable expenses incurred by the person unless the 
proceeding was one by or in the right of the Corporation, in which case 
indemnification may be made only against reasonable expenses, provided that 
such person is not ultimately adjudged to be liable to the Corporation.

     (3)  AUTHORIZATION OF INDEMNIFICATION.  Indemnification under paragraph 
(2) of this Article shall not be made unless authorized in the specific case 
after a determination has

                                      -3-


<PAGE>

been made that indemnification of the person is permissible because such 
person has met the standards of conduct set forth in said paragraph (2).  
This determination shall be made by (i) a majority vote of a quorum of the 
directors not parties to the proceeding or, if such a quorum cannot be 
obtained, by a majority vote of a committee of the Board, consisting of not 
less than two (2) directors, designated by a majority of the full Board, (ii) 
special legal counsel appointed by the Board or a committee of the Board in 
the same manner as a determination is made in accordance with (i) above, or 
(iii) by the stockholders.

     Authorization of indemnification shall be made in the same manner as the 
determination that indemnification is permissible except in cases where such 
determination is made by special legal counsel in which event such 
authorization shall be made in the same manner in which special legal counsel 
is appointed.

     (4)  PAYMENT OF EXPENSES IN ADVANCE OF FINAL DISPOSITION OF A 
PROCEEDING.  The Corporation may pay the expenses of a director, officer, 
employee or agent of the Corporation who is a party to a proceeding, in 
advance of its final disposition, after a determination that the facts then 
known would not preclude indemnification, upon receipt by the Corporation of 
(i) a written affirmation by such person of his good faith belief that the 
standard of conduct necessary for indemnification has been met and (ii) a 
written undertaking by such person, or on his behalf, to repay the amount so 
advanced if it is ultimately determined that the standard of conduct has not 
been met.  Such determination and authorization shall be made in the same 
manner as specified in paragraph (3) of this Article.

                                      -4-

                                       3

<PAGE>

                    (b)  BOARD SIZE.  Except as set forth in subparagraph 2(c)
below, the number of directors of the Company shall be five (5). The holders of
the Class C Convertible Preferred Stock, voting as a separate class, shall be
entitled to elect two (2) directors of the Company.

                    (c)  INCREASE IN BOARD SIZE.  If any Trigger Event of the
type described in subparagraph 2(d) has occurred, and the Company has not
redeemed the Class C Convertible Preferred Stock pursuant to subparagraph 2(f),
the number of directors constituting the Company's board of directors will, at
the request of the holders of a majority of the shares of Class C Convertible
Preferred Stock then outstanding, be increased by two (2) to a total of seven
(7), and the holders of Class C convertible Preferred Stock will have the
special right, voting separately as a single class (with each share of Class C
Convertible Preferred Stock being entitled to one vote) and to the exclusion of
all other classes of the Company's stock, to elect individuals to fill both such
newly created directorships, to remove any individuals elected to such
directorships, and to fill any vacancies in such directorships.  The special
right of the holders of Class C Convertible Preferred Stock to elect or remove
members of the board of directors may be exercised at a special meeting called
as provided below, at any annual or special meeting of stockholders, or by
written consent in lieu of a stockholders meeting.  Subject to the provisions of
subparagraph 2(d) below, such special right will continue until such time as
there is no longer any Trigger Event in existence, at which time such special
right will terminate subject to revesting upon the occurrence of any further
Trigger Event which gives rise to such special right hereunder.

          At any time when such special right has vested in the holders of Class
C Convertible Preferred Stock, a proper officer of the Company will, upon the
written request of the holders of at least 1O% of the shares of Class C
Convertible Preferred Stock then outstanding, addressed to the Secretary of the
Company, call a special meeting of the holders of Class C Convertible Preferred
Stock for the purpose of electing directors pursuant to this subparagraph.  Such
meeting will be held at the earliest legally permissible date at the principal
office of the Company or at such other place designated by the holders of at
least 10% of the shares of Class C Convertible Preferred Stock then outstanding.
If such meeting has not been called by a proper officer of the Company within 10
days after personal service of such written request upon the Secretary of the
Company or within 20 days after mailing the same to the Secretary of the Company
at the Company's principal office, then the holders of at least 10% of the of
Class C Convertible Preferred Stock then outstanding may designate in writing
one of their number to call such meeting at the expense of the Company, and such
meeting may be called by such person so designated upon the shortest legally
permissible notice and will be held at the Company's principal office, or at
such other place designated by the holders of at least 10% of the shares of
Class Convertible Preferred Stock then outstanding.  Any holder of Class C
Convertible Preferred Stock so designated will be given access to the stock
record books of the Company for the purpose of causing a meeting of stockholders
to be called pursuant to this subparagraph.

          At any meeting or at any adjournment thereof at which the holders of
Class C Convertible Preferred Stock have the special right to elect directors,
the presence, in person

                                       4

<PAGE>

or by proxy, of the holders of a majority of the shares of Class C 
Convertible Preferred Stock then outstanding will be required to constitute a 
quorum for the election or removal of any director by the holders of the 
Class C Convertible Preferred Stock exercising such special right.  The vote 
of a majority of such quorum will be required to elect or remove any such 
director.

          If any Trigger Event exists, each holder of Class C Convertible
Preferred Stock will also have any other rights which such holder may have
pursuant to applicable law.

                    (d)  TRIGGER EVENT OCCURRENCE.  A Trigger Event for the
purposes of paragraph c will be deemed to have occurred if:

                         (i)  as at the close of the fiscal year ending June 30,
1992, the Adjusted Book Value of the Company (as defined in paragraph 2(e)
below) does not exceed 75% of the book value of the Company at the close of the
fiscal year ending June 30, 1991;

                         (ii) as at the close of the fiscal year ending June 30,
1993, the Business Value of the Company (as defined in paragraph 2(e) below)
does not exceed 50% of the Investment Value of the Company (as defined in
paragraph 2(e) below);

                         (iii)     as at the close of the fiscal year ending
June 30, 1994, the Business Value of the Company does not exceed 75% of the
Investment Value of the Company;

                         (iv) as at the close of the fiscal year ending June 30,
1995, the Business Value of the Company does not exceed 100% of the Investment
Value of the Company; or

                         (v)  as at the close of the fiscal year ending June 30,
1996, the Business Value of the Company does not exceed 100% of the Investment
Value of the Company.

          The determination of whether a Trigger Event has occurred shall be
made by the holders of a majority of the Class C Convertible Preferred Stock at
the time audited financial statements for the applicable period are received by
the holders of Class C Convertible Preferred Stock; provided, however, that if
audited financial statements are not received within 120 days of the end of the
applicable period, the determination of whether a Trigger Event has occurred
shall be made by the holders of a majority of the Class C Convertible Preferred
Stock based upon the most current financial statements they have received from
the Company.  Notwithstanding the provisions of this subparagraph, if a Trigger
Event has occurred and the Company as at the end of the next fiscal quarter
achieves a ratio of Business Value to Investment Value over the immediately
preceding four fiscal quarters which exceeds the minimum ratio of Business Value
to Investment Value which was to have been achieved to avoid a Trigger Event,
the Board shall revert to five (5) directors and the right of the holders of

                                       5

<PAGE>

Class C Convertible Preferred Stock to elect two (2) additional directors 
shall be suspended until the next Trigger Event occurs.

                    (e)  DEFINITION.  "Adjusted Book Value of the Company" shall
mean the book value, determined in accordance with genera1ly accepted accounting
principles consistently applied, less the amount of the proceeds from the sale
of Class C Convertible Preferred Stock which has not yet been expended for
marketing expenses or other usual working capital needs.  "Business Value of the
Company" shall mean (a) eight times earnings before interest and taxes,
exclusive of any extraordinary items, plus total cash and cash equivalents held
by the Company, less the sum of (i) its interest bearing debt and (ii) the value
of its Preferred Stock other than Class C Convertible Preferred Stock, all
determined in accordance with generally accepted accounting principles
consistently applied.  "Investment Value of the Company" shall mean the number
of shares of the Company's Common Stock then outstanding multiplied by the
Conversion Price (assuming for purposes of this calculation that all issued and
outstanding options and warrants have been exercised, and that all convertible
securities have been converted).

                    (f)  RIGHT TO REDEEM.  If the holders of Class C Convertible
Preferred Stock notify the Company their election to exercise their rights under
this paragraph 2, then the Company shall have ninety days from the receipt of
such notice to redeem all of the Class C Convertible Preferred Stock at a price
per share equal to $5.14 increased at a compound annual rate of 12% from the
date the Stock was issued through the date it is redeemed.

               (3)  DIVIDENDS.  Commencing on November 1, 1992, the holders of
the Class C Convertible Preferred Stock shall be entitled to receive, out of
funds legally available therefor, (a) if, and when declared by the Board of
Directors, and (b) upon the liquidation or winding up of the Company or
redemption of the Class C Convertible Preferred Stock, semi-annual dividends in
the amount of $0.206 per share (the "Accruing Dividends").  Accruing Dividends
shall in any event accrue from day to day, whether or not earned or declared,
and shall be cumulative.  If the Board of Directors has been expanded pursuant
to the terms of paragraph 2 above, any declaration of dividends shall require
the affirmative vote of a majority of the directors elected by the holders of
Common Stock.

               (4)  LIQUIDATION.  Upon any liquidation, dissolution or winding
up of the Company, whether voluntary or involuntary, the holders of the shares
of Class C Convertible Preferred Stock shall be entitled, before any
distribution or payment is made upon any stock ranking on liquidation junior to
the Class C Convertible Preferred Stock, to be paid an amount equal to the
greater of (i) $5.14 per share plus, in the case of each share, an amount equal
to all Accruing Dividends unpaid thereon (whether or at declared) and any other
dividends declared but unpaid thereon, computed to the date payment hereof is
made available, or (ii) such amount per share as would have been payable had
each such share been converted into Common Stock pursuant to paragraph 6
immediately prior to such liquidation, dissolution or winding up; and the
holders of Class C Convertible Preferred Stock shall not be entitled to any
further payment, such amount payable with respect to one share of Class C
Convertible Preferred Stock being sometimes referred to as the "Liquidation
Payment" and with respect to

                                       6

<PAGE>

all shares of Class Convertible Preferred Stock being sometimes referred 
to as the "Liquidation Payments".  If upon such liquidation, dissolution or 
winding up of the Company, whether voluntary or involuntary, the assets to be 
distributed among the holders of Class C Convertible Preferred Stock shall be 
insufficient to permit payment to the holders of Class C Convertible 
Preferred Stock of the amount distributable as aforesaid, the entire assets 
of the Company to be so distributed shall be distributed ratably among the 
holders of Class C Convertible Preferred Stock. Upon any such liquidation, 
dissolution or winding up of the Company, after the holders of Class C 
Convertible Preferred Stock shall have been paid in full the amounts to which 
they shall be entitled, the remaining net assets of the Company may be 
distributed to holders of stock ranking on liquidation junior to the Class C 
Convertible Preferred Stock.  Written notice of such liquidation, dissolution 
or winding up, stating a payment date, the amount of the Liquidation 
Payments, and the place where said Liquidation Payments shall be payable, 
shall be given by mail, postage prepaid, or by telex to non-United States 
residents, not less than 20 days prior to the payment date stated therein, to 
the holders of record of Class C Convertible Preferred Stock, such notice to 
be addressed to each such holder at its address as shown by the records  of 
the Company.  The consolidation or merger of the Company into or with any 
other entity or entities which results in the exchange of outstanding shares 
of the Company for securities or other consideration issued or paid or caused 
to be issued or paid by any such entity or affiliate thereof, and the sale or 
transfer by the Company of all or substantially all its assets, shall be 
deemed to be a liquidation, dissolution or winding up of the Company within 
the meaning of the provisions of this paragraph 4 unless the holders of a 
majority of the Class C Convertible Preferred Stock then outstanding elect 
otherwise in a writing filed with the Secretary of the Company.

               (5)  RESTRICTIONS.  Except where the vote or written consent of
the holders of a greater number of shares of the Company is required by law or
by the Articles of Incorporation, and in addition to any other vote required by
law or the Articles of Incorporation, without the approval of the holders of at
least a majority of the then outstanding shares of Class C Convertible Preferred
Stock, given in writing or by vote at a meeting, consenting or voting (as the
case may be) separately as a class, the Company will not:

                    (a)  Create or authorize the creation of any additional
class or series of shares of stock unless the same ranks junior to the Class C
Convertible Preferred Stock as to the distribution of assets on the liquidation,
dissolution or winding up of the Company, or increase the authorized amount of
the Class C Convertible Preferred Stock, or increase the authorized amount of
any additional class or series of shares of stock unless the same ranks junior
to the Class C Convertible Preferred Stock as to the distribution of assets on
the liquidation, dissolution or winding up the Company, or create or authorize
any obligation or security convertible into shares of Class C Convertible
Preferred Stock or into shares of any other class or series of stock unless the
same ranks junior to the Class C Convertible Preferred Stock as to the
distribution of assets on the liquidation, dissolution or winding up of the
Company, whether any such creation, authorization or increase shall be by means
of amendment to the Articles of Incorporation or by merger, consolidation or
otherwise;

                                       7

<PAGE>

                    (b)  Consent to any liquidation, dissolution or winding up
of the Company, or consolidate or merge into or with any other entity or
entities, or sell or transfer all or substantially all its assets;

                    (c)  Amend, alter or repeal its Amended and Restated
Articles of Incorporation;

                    (d)  Purchase or set aside any sums for the purchase of, or
pay any dividend or make any distribution on, any shares of stock other than the
Class C Convertible Preferred Stock, except for dividends or other distributions
payable on the Common Stock solely in the form of additional shares of Common
Stock, and except for the purchase of shares of Common Stock from former
employees of the Company who acquired such shares directly from the Company, if
each such purchase is made pursuant to contractual rights held by the Company
relating to the termination of employment of such former employee;

                    (e)  Redeem or otherwise acquire any shares of Class C
Convertible Preferred Stock except as expressly authorized in paragraph 7
hereof, or pursuant to a purchase offer made pro rata to all holders of the
shares of Class C Convertible Preferred Stock on the basis of the aggregate
number of outstanding shares of Class C Convertible Preferred Stock then held by
each such holder;

                    (f)  Change the scope of business activity of the Company
other than in the ordinary course of business; or

                    (g)  Change the size of the Board of Directors.

               (6)  CONVERSION.  The holders of shares of Class C Convertible
Preferred Stock shall have the following rights and obligations with regard to
the conversion of Class C Convertible Preferred Stock into Common Stock:

                    (a)  (1)  RIGHT TO CONVERT.  Subject to the terms and
conditions of this paragraph 6, the holder of any share or shares of Class C
Convertible Preferred Stock shall have the right, at its option at any time, to
convert any such shares of Class C Convertible Preferred Stock (except that upon
any liquidation of the Company the right of conversion shall terminate at the
close of business on the business day fixed for payment of the amount
distributable on the Class C Convertible Preferred Stock) into such number of
fully paid and non-assessable shares of Common Stock as is obtained by (i)
multiplying the number of shares of Class C Convertible Preferred Stock so to be
converted by $5.14, and (ii) dividing the result by the conversion price of
$5.14 per share or, in case an adjustment of such price has taken place pursuant
to the further provisions of this paragraph 6, then by the conversion price as
last adjusted and in effect at the date any share or shares of Class C
Convertible Preferred stock are surrendered for conversion (such price, or such
price as last adjusted, being referred to as the "Conversion Price").  Such
right of conversion shall be exercised by the holder thereof by giving written
notice that the holder elects to convert a stated number of shares of Class C


                                       8

<PAGE>

Convertible Preferred Stock into Common Stock, and by surrender of a 
certificate or certificates for the shares so to be converted to the Company 
at its principal office (or such other office or agency of the Company as the 
Company may designate by notice in writing to the holders of the Class C 
Convertible Preferred Stock) at any time during its usual business hours on 
the date set forth in such notice, together with a statement of the name or 
names (with address) in which the certificate or certificates for shares of 
Common Stock shall be issued.

                         (2)  AUTOMATIC CONVERSION. The Class C Convertible
Preferred Stock will be automatically converted into shares of the Company's
Common Stock at the then applicable Conversion Price, on the effective date of
the registration statement for an underwritten public offering of shares of
Common Stock at a price to the public of not less than $9.50 per share, yielding
net proceeds to the Company of not less than $7,500,000.

                    (b)  ISSUANCE OF CERTIFICATES; TIME CONVERSION EFFECTED. 
Promptly after the receipt of the written Notice referred to in subparagraph
6(a)(1) and surrender of the certificate or certificates for the share or shares
of Class C Convertible Preferred Stock to be converted, the Company shall issue
and deliver, or cause to be issued and delivered, to the holder, registered in
such name or names as such holder may direct, a certificate or certificates for
the number of whole shares of Common Stock issuable upon the conversion of such
share or shares of Class C Convertible Preferred Stock. To the extent permitted
by law, such conversion shall be deemed to have been effected and the Conversion
Price shall be shall be determined as of the close of business on the date on
which such written notice shall have been received by the Company and the
certificate or certificate for such share or shares shall have been surrendered
as aforesaid, and at such time the rights of the holder of such share or shares
of Class C Convertible Preferred Stock shall cease, and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock
shall be issuable upon such conversion shall be deemed to have become the holder
or holders of record of the shares represented thereby.

                    (c)  FRACTIONAL SHARES; DIVIDENDS; PARTIAL CONVERSION.  No
fractional shares shall be issued upon conversion of Class C Convertible Stock
into Common Stock, and no payment or adjustment shall be made upon any
conversion on account of any cash dividends on the Common Stock issued upon such
conversion.  At the time of each conversion, the Company shall pay in cash an
amount equal to all dividends, excluding Accruing Dividends, accrued and unpaid
on the shares of Class C Convertible Preferred Stock surrendered for conversion
to the date upon which such conversion is deemed to take place as provided in
subparagraph 6(b).  In case the number of shares of Class C Convertible
Preferred Stock represented by the certificate or certificates surrendered
pursuant to subparagraph 6(a) exceeds the number of shares converted, the
Company shall, upon such conversion, execute and deliver to the holder, at the
expense of the Company, a new certificate or certificates for the number of
shares of Class C Convertible Preferred Stock represented by the certificate or
certificates surrendered which are not to be converted.  If any fractional share
of Common Stock would, except for the provisions of the first sentence of this
subparagraph 6(c), be delivered upon such conversion, the Company, in lieu of
delivering such fractional share, shall pay to the holder surrendering the Class
C Convertible Preferred Stock for conversion an

                                       9

<PAGE>

amount in cash equal to the current market price of such fractional share as 
determined in good faith by the Board of Directors of the Company.

                    (d)  ADJUSTMENT OF PRICE UPON ISSUANCE OF COMMON STOCK. 
Except as provided in subparagraph 6(e), if and whenever the Company shall issue
or sell, or is, in accordance with subparagraphs 6(d)(1) through 6(d)(6), deemed
to have issued or sold, any shares of Common Stock for a consideration per share
less than the Conversion Price in effect immediately prior to the time of such
issue or sale, then, forthwith upon such issue or sale, the Conversion Price
shall be reduced to a price determined by multiplying that Conversion Price by a
fraction (i) the numerator of which shall be (A) the number of shares of Common
Stock outstanding prior to such issue or sale, plus (B) the number of shares of
Common Stock that the aggregate consideration received by the Company for the
total number of shares of Common Stock so issued or sold would purchase at such
Conversion Price, and (ii) the denominator of which shall be the number of
shares of Common Stock outstanding immediately prior to such issue or sale plus
the number of shares of Common Stock so issued or sold.

          For purposes of this subparagraph 6(d), the following subparagraphs
6(d)(1) to 6(d)(6) shall also be applicable:

                         (1)  ISSUANCE OF RIGHTS OR OPTIONS.  In case at any
time the Company shall in any manner grant (whether directly or by assumption in
a merger or otherwise) any warrants or other rights to subscribe for or to
purchase, or any options for the purchase of, Common Stock or any stock or
security convertible into or exchangeable for Common Stock (such warranties,
rights or options being called "Options" and such convertible or exchangeable
stock or securities being called "Convertible Securities") whether or not such
options or the right to convert or exchange any such Convertible Securities are
immediately exercisable, and the price per share for which Common Stock is
issuable upon the exercise of such Options or upon the conversion or exchange of
such Convertible Securities shall be less than the Conversion Price in effect
immediately prior to the time of the granting of such Options, then the total
maximum number of shares of Common Stock issuable upon the exercise of such
Options shall be deemed to have been issued for such price per share as of the
date of granting of such Options or the issuances of such Convertible Securities
and thereafter shall be deemed to be outstanding.  Except as otherwise provided
in subparagraph 6(d)(3), no adjustment of the Conversion Price shall be made
upon the actual issue of such Common Stock or of such Convertible Securities
upon exercise of such Options or upon the actual issue of such Common Stock upon
conversion or exchange of such Convertible Securities.

                         (2)  ISSUANCE OF CONVERTIBLE SECURITIES.  In case the
Company shall in any manner issue (whether directly or by assumption in a merger
or otherwise) or sell any Convertible Securities, whether or not the rights to
exchange or convert any such Convertible Securities are immediately exercisable,
and the price per share for which Common Stock is issuable upon such conversion
or exchange shall be less than the Conversion Price in effect immediately prior
to the time of such issue or sale, then the total maximum number of shares of
Common Stock issuable upon conversion or exchange of all such Convertible
Securities shall be deemed to have been issued for such price per share as of
the

                                       10

<PAGE>

date of the issue or sale of such Convertible Securities and thereafter shall 
be deemed to be outstanding, provided that (a) except as otherwise provided 
in subparagraph 6(d)(3), no adjustment of the Conversion Price shall be made 
upon the actual issue of such Common Stock upon conversion or exchange of 
such Convertible Securities, and (b) if any such issue or sale of such 
Convertible Securities is made upon exercise of any Options to purchase any 
such Convertible Securities for which adjustments of the Conversion Price 
have been or are to be made pursuant to other provisions of this subparagraph 
6(d), no further adjustment of the Conversion Price shall be made by reason 
of such issue or sale.

                         (3)  DETERMINATION OF PRICE PER SHARE; CHANGE IN OPTION
PRICE OR CONVERSION RATE.  The price per share for which Common Stock is
issuable upon the exercise of Options or the conversion or exchange of
Convertible Securities shall be determined by dividing (i) the total amount
received or receivable by the Company as consideration for the issue or sale of
such Options or Convertible Securities, plus the minimum aggregate amount of
additional consideration, if any, payable to the Company upon the exercise of
all such Options or the conversion or exchange of such Convertible Securities,
by (ii) the total maximum number of shares of Common Stock issuable upon the
exercise of all such Options or the conversion or exchange of all such
Convertible Securities.  Upon the happening of any of the following events,
namely, if the purchase price provided for in any Option referred to in
subparagraph 6(d)(1), the additional consideration, if any, payable upon the
conversion or exchange of any Convertible Securities referred to in subparagraph
6(d)(1) or 6(d)(2), or the rate at which Convertible Securities referred to in
subparagraph 6(d)(1) or 6(d)(2) are convertible into or exchangeable for Common
Stock shall change at any time (including, but not limited to, changes under or
by reason of provisions designed to protect against dilution), the Conversion
Price in effect at the time of such event shall forthwith be readjusted to the
Conversion Price which would have been in effect at such time had such Options
or Convertible Securities still outstanding provided for such changed purchase
price, additional consideration or conversion rate, as the case may be, at the
time initially granted, issued or sold, but only if as a result of such
adjustment the Conversion Price then in effect hereunder is thereby reduced; and
on the expiration of any such Option or the termination of any such right to
convert or exchange such Convertible Securities, the Conversion Price then in
effect hereunder shall forthwith be increased to the Conversion Price which
would have been in effect at the time of such expiration or termination had such
Option or Convertible Securities, to the extent outstanding immediately prior to
such expiration or termination, never been issued.

                         (4)  STOCK DIVIDENDS.  If the Company shall declare a
dividend or make any other distribution upon any stock of the Company payable in
Common Stock (except for dividends or distributions upon the Common Stock),
Options, or Convertible Securities, any Common Stock, Options or Convertible
Securities, as the case may be, issuable in payment of such dividend or
distribution shall be deemed to have been issued or sold without consideration.

                         (5)  CONSIDERATION FOR STOCK.  If any shares of Common
Stock, Options, or Convertible Securities shall be issued or sold for cash, the
consideration received therefor shall be deemed to be the amount received by the
Company therefor, without

                                       11

<PAGE>

deduction therefrom of any expenses incurred or any underwriting commissions 
or concessions paid or allowed by the Corporation in connection therewith.  
In case any shares of Common Stock, Options, or Convertible Securities shall 
be issued or sold for a consideration other than cash, the amount of the 
consideration other than cash received by the Company shall be deemed to be 
the fair value of such consideration as determined in good faith by the Board 
of Directors of the Company, without deduction of any expenses incurred or 
any underwriting commissions or concessions paid or allowed by the Company in 
connection therewith.  In case any Options shall be issued in connection with 
the issue and sale of other securities of the Company, together comprising 
one integral transaction in which no specific consideration is allocated to 
such Options by the parties thereto, such Options shall be deemed to have 
been issued for such consideration as determined in good faith by the Board 
of Directors of the Company.

                         (6)  RECORD DATE.  If the Company shall take a record
of the holders of its Common Stock for the purpose of entitling them (i) to
receive a dividend or other distribution payable in Common Stock, Options, or
Convertible Securities or (ii) to subscribe for or purchase Common Stock,
Options, or Convertible Securities, then such record date shall be deemed to be
the date of the issue or sale of the shares of Common Stock deemed to have been
issued or sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                    (e)  CERTAIN ISSUES OF COMMON STOCK EXCEPTED.  Anything
herein to the contrary notwithstanding, the Company shall not be required to
make any adjustment of the Conversion Price in the case of the issuance of any
Options or shares of Common Stock to employees under the Omnibus Stock Plan or
non-employee directors under the Stock Option Plan for Directors.

                    (f)  SUBDIVISION OR COMBINATION OF COMMON STOCK.  If the
Company shall at any time subdivide (by stock split, stock dividend or
otherwise) its outstanding shares of Common Stock into greater number of shares,
the Conversion Price in effect immediately prior to such subdivision shall be
proportionately reduced, and, conversely, in case the outstanding shares of
Common Stock shall be combined into a smaller number of shares, the Conversion
Price in effect immediately prior to such combination shall be proportionately
increased.

                    (g)  REORGANIZATION OR RECLASSIFICATION.  If any capital 
reorganization or reclassification of the capital stock of the Company shall 
be effected in such a way that holders of Common Stock shall be entitled to 
receive stock, securities or assets with respect to or in exchange for Common 
Stock, then, as a condition of such reorganization or reclassification, 
lawful and adequate provisions shall be made whereby each holder of a share 
or shares of Class C Convertible Preferred Stock shall thereupon have the 
right to receive, upon the basis and upon the terms and conditions specified 
herein and in lieu of the shares of Common Stock immediately theretofore 
receivable upon the conversion of such share or shares of Class C Convertible 
Preferred Stock, such shares of stock, securities or assets as may be issued 
or payable with respect to or in exchange for a number of outstanding shares 
of such

                                       12

<PAGE>

Common Stock equal to the number of shares of such Common Stock immediately 
theretofore receivable upon such conversion had such reorganization or 
reclassification not taken place, and in any such case appropriate provisions 
shall be made with respect to the rights and interests of such holder to the 
end that the provisions hereof (including without limitation provisions for 
adjustment of the Conversion Price) shall hereafter be applicable, as nearly 
as may be, in relation to any shares of stock, securities or assets hereafter 
deliverable upon the exercise of such conversion rights.

                    (h)  NOTICE OF ADJUSTMENT.  Upon any adjustment of the
Conversion Price, then and in each such case the Company shall give written
notice thereof, by first class mail, postage prepaid, or by telex to non-United
States residents, addressed to each holder of shares of Class C Convertible
Preferred Stock at the address of such holder as shown on the books of the
Company, which notice shall state the Conversion Price resulting from such
adjustment, setting forth in reasonable detail the method upon which such
calculation is based.

                    (i)  OTHER NOTICES.  In case at any time:

                         (1)  the Company shall declare any dividend upon its
Common Stock payable in cash or stock, or make any other distribution to the
holders of its Common Stock;

                         (2)  the Company shall offer for subscription pro rata
to the holders of its Common Stock any additional shares of stock of any class
or other rights;

                         (3)  there shall be any capital reorganization or
reclassification of the capital stock of the Company, or a consolidation or
merger of the Company with or into, or a sale of all or substantially all its
assets to, another entity or entities; or

                         (4)  there shall be a voluntary or involuntary
dissolution, liquidation or winding up of the Company;

then, in any one or more of said cases, the Company shall give, by first class
mail, postage prepaid, or by telex to non-United States residents, addressed to
each holder of any shares of Class C Convertible Preferred Stock at the address
of such holder as shown on the books of the Company, (a) at least 20 days' prior
written notice of the date on which the books of the Company shall close or a
record shall be taken for such dividend, distribution or subscription rights or
for determining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up and (b) in the case of any such reorganization, reclassification
consolidation, merger, sale, dissolution, liquidation or winding up, at least 20
days prior written notice of the date when the same shall take place.  The
notice provided in accordance with the foregoing clause (a) shall specify, in
the case of any such dividend, distribution or subscription rights, the date on
which the holders of Common Stock shall be entitled thereto.  The notice
provided in accordance with the foregoing clause (b) shall specify the date on
which the holders of Common Stock shall be entitled to exchange their

                                       13

<PAGE>

Common Stock for securities or other property deliverable upon such 
reorganization, reclassification, consolidation, merger, sale, dissolution, 
liquidation or winding up, as the case may be.

                    (j)  STOCK TO BE RESERVED.  The Company will at all times
reserve and keep available out of its authorized Common Stock, solely for the
purpose of issuance upon the conversion of Class C Convertible Preferred Stock
as herein provided, such number of shares of Common Stock as shall then be
issuable upon the conversion of all outstanding shares of Class C Convertible
Preferred Stock.  The Company covenants that all shares of Common Stock which
shall be so issued shall be duly and validly issued and fully paid and non-
assessable and free from all taxes, liens and charges with respect to the issue
thereof, and, without limiting the generality of the foregoing, the Company
covenants that it will from time to time take all such action as may be
requisite to assure that the par value per share of the Common Stock is at all
times equal to or less than the Conversion Price in effect at the time.  The
Company will take all such action as may be necessary to assure that all such
shares of Common Stock may be so issued without violation of any applicable law
or regulation, or of any requirement of any national securities exchange upon
which the Common Stock may be listed.  The Company will not take any action
which results in any adjustment of the Conversion Price if the total number of
shares of Common Stock issued and issuable after such action upon conversion of
the Class C Convertible Preferred Stock would exceed the total number of shares
of Common Stock then authorized by the Articles of Incorporation.

                    (k)  NO REISSUANCE OF CLASS C CONVERTIBLE PREFERRED STOCK. 
Shares of Class C Convertible Preferred Stock which are converted into shares of
Common Stock as provided herein shall not be reissued.

                    (l)  ISSUE TAX.  The issuance of certificates for shares of
Common Stock upon conversion of Class C Convertible Preferred Stock shall be
made without charge to the holders thereof for any issuance tax in respect
thereof, provided that the Company shall not be required to pay any tax which
may be payable in respect of any transfer involved in the issuance and delivery
of any certificate in a name other than that of the holder of the Class C
Convertible Preferred Stock which is being converted.

                    (m)  CLOSING OF BOOKS.  The Company will at no time close
its transfer books against the transfer of any Class C Convertible Preferred
Stock or of any shares of Common Stock issued or issuable upon the conversion of
any shares of Class C Convertible Preferred Stock in any manner which interferes
with the timely conversion of such Class C Convertible Preferred Stock, except
as may otherwise be required to comply with applicable securities laws.

                    (n)  DEFINITION OF COMMON STOCK.  As used in this paragraph
6, the term "Common Stock" shall mean and include the Company's authorized
Common Stock, par value $0.01 per share, as constituted on the date of filing of
these Articles of Amendment and Restatement, and shall also include any capital
stock of any class of the Company thereafter authorized which shall not be
limited to a fixed sum or percentage of par

                                       14

<PAGE>

value in respect of the rights of the holders thereof to participate in 
dividends or in the distribution of assets upon the voluntary or involuntary 
liquidation, dissolution or winding up of the Company; provided that the 
shares of Common Stock receivable upon conversion of shares of Class C 
Convertible Preferred Stock shall include only shares designated as Common 
Stock of the Company on the date of filing of this instrument, or in case of 
any reorganization or reclassification of the outstanding shares thereof, the 
stock, securities or assets provided for in subparagraph 6(g).

                    (o)  TERMINATION OF CERTAIN RIGHTS.  Upon the conversion of
an aggregate of eighty percent (80%) or more of the Class C Convertible
Preferred Stock into Common Stock pursuant to the terms of this paragraph 6, the
rights of the Class C Convertible Preferred Stock set forth in subparagraphs
2(c), 2(d), 2(e), and 2(f) and paragraph 5 shall terminate.

          7.   REDEMPTION.  The shares of Class C Convertible Preferred Stock
shall be redeemable as follows:

               (a)  REDEMPTION DATES.  On September 15, 1995 (the "First
Redemption Date"), the Company shall redeem from each holder of shares of Class
C Convertible Preferred Stock, one-third of the shares of Class C Convertible
Preferred Stock held by such holder on the First Redemption Date.  On September
15, 1996 (the "Second Redemption Date"), the Company shall redeem from each
holder of shares of Class C Convertible Preferred Stock one-half of the
remaining shares of Class C Convertible Preferred stock held by such holder on
the Second Redemption Date, plus any shares eligible for redemption on the First
Redemption Date but not previously redeemed by the Company.  On September 15,
1997 (the "Third Redemption Date"), the Company shall redeem from each holder of
shares of Class C Convertible Preferred Stock all of the remaining shares of
Class C Convertible Preferred Stock held by such holder on the Third Redemption
Date, plus any shares eligible for redemption on the First Redemption Date and
the Second Redemption Date, but not previously redeemed by the Company.  For
purposes of these Amended and Restated Articles of Incorporation, each of the
First Redemption Date, Second Redemption Date and Third Redemption Date is
sometimes referred to herein as a "Redemption Date."

               (b)  REDEMPTION PRICE AND PAYMENT.  The Class C Convertible
Preferred Stock to be redeemed on each Redemption Date pursuant paragraph 7(a)
shall be redeemed by paying for each share in cash an amount equal to $5.14 per
share plus, in the case of each share, an amount equal to all Accruing Dividends
unpaid thereon (whether or not declared) and any other dividends declared but
unpaid hereon, computed to such Redemption Date (such amount be referred to as
the "Mandatory Redemption Price").

               (c)  REDEMPTION MECHANICS.  At least 20 but not more than 30 days
prior to each Redemption Date, written notice (the "Redemption Notice") shall be
given by the Company by mail, postage prepaid, or by telex to non-U.S.
residents, to each holder of record (at the close of business on the business
day next preceding the day on which the Redemption Notice is given) of shares of
Class C Convertible Preferred Stock notifying such holder of the

                                       15

<PAGE>

redemption and specifying the number of shares eligible for redemption, the 
Redemption Price, the Redemption Date, and the place where the said 
Redemption Price shall be payable.  The Redemption Notice shall be addressed 
to each holder at his address as shown by the records of the Company.  From 
and after the close of business on such Redemption Date, unless there shall 
have been a default in the payment of the Redemption Price, all rights of 
holders of shares of Class C Convertible Preferred Stock (except the right to 
receive the Redemption price) shall cease with respect to such shares so 
redeemed, and such shares shall not thereafter be transferred on the books of 
the Company or be deemed to be outstanding for any purpose whatsoever.  The 
shares of Class C Convertible Preferred Stock not redeemed shall remain 
outstanding and entitled to all rights and preferences provided herein.

          If the funds of the Company legally available for redemption of shares
of Class C Convertible Preferred Stock on any Redemption Date are insufficient
to redeem the total number of shares of Class C Convertible Preferred Stock
eligible for redemption on such date, the holders of shares of Class C
Convertible Preferred Stock shall share ratably in any funds legally available
for redemption of such shares according to the respective amounts which would be
payable with respect to the full number of shares owned by them if all such
shares eligible for redemption on such date were redeemed in full.  The shares
of Class C Convertible Preferred Stock not redeemed shall remain outstanding and
entitled to all rights and preferences provided herein.  At any time thereafter
when additional funds of the Company are legally available for the redemption of
such shares of Class C Convertible Preferred Stock, such funds will be used, at
the end of the next succeeding fiscal quarter, to redeem the balance of such
shares, or such portion thereof for which funds are then legally available, on
the basis set forth above.

               (d)  REDEEMED OR OTHERWISE ACQUIRED SHARES TO BE RETIRED.  Any
shares of Class C Convertible Preferred Stock redeemed pursuant to this
paragraph 7 or otherwise acquired by the Company in any manner whatsoever shall
be cancelled and shall not under any circumstances be reissued; and the Company
may from time to time take such appropriate corporate action as may be necessary
to reduce accordingly the number of authorized shares of Class C Convertible
Preferred Stock.

          8.   AMENDMENTS.  No provision of these terms of the Class C
Convertible Preferred Stock may be amended, modified or waived without the
written consent or affirmative vote of the holders of at least two-thirds of the
then outstanding shares of Class C Convertible Preferred Stock.

               SIXTH:    The number of directors of the Company shall be five
(5), which number may be increased or decreased pursuant to the By-Laws of the
Company; provided, however, that the number shall be increased to seven (7) if
so required pursuant to Article FIFTH, paragraph C(2)(c).  The names of the
directors who shall act until their successors are duly chosen and qualified are
George T. Jimenez, Paul G. Casner and Graham Hartwell.

                                       16

<PAGE>

               SEVENTH:  (a)  To the fullest extent that limitations on the
liability of directors, officers, employees and agents are permitted by the
Maryland General Corporation Law, no director, officer, employee or agent of the
Company shall have any liability to the Company or its stockholders for damages.
This limitation on liability applies to events occurring at the time a person
serves as a director, officer, employee or agent of the Company, whether or not
such person is serving as such at the time of any proceeding in which liability
is asserted.

               (b)  The Company shall indemnify and advance expenses to its
currently acting and its former directors to the fullest extent that
indemnification of directors is permitted by the Maryland General Corporation
Law.  The Company shall indemnify and advance expenses to its officers to the
same extent as its directors and may do so to such further extent as is
consistent with law.  The Board of Directors may by Bylaw, resolution or
agreement make further provision for indemnification of directors, officers,
employees and agents to the fullest extent permitted by the Maryland General
Corporation Law.

               (c)  References to the Maryland General Corporation Law in this
Article are to that law as from time to time amended.  No amendment to the
charter of the Company shall affect any right of any person under this Article
based on any event, omission or proceeding prior to the amendment.

          SECOND:  The amendment and restatement of the charter of the Company
herein was duly and unanimously approved and advised by the Board of Directors
on October 29, 1991, and was approved by the affirmative vote of the
stockholders of the Company as required by the Maryland General Corporation Law
on November 9, 1991.

          THIRD:  The Amendment and Restatement of the charter of the Company as
hereinabove set forth has been duly advised by the board of directors and

given timely notice thereof in writing to the Secretary.  To be timely, such
stockholder's notice must be delivered to or mailed and received by the
Secretary at the principal executive offices of the Corporation, not less than
20 days nor more than 30 days prior to the meeting (or, with respect to a
proposal required to be included in the Company's proxy statement pursuant to
Rule 14a-8 of the Securities Exchange Act of 1934, or its successor provision,
the earlier date such proposal was received); provided, however, that in the
event that less than 30 days' notice or prior public disclosure of the date of
the meeting is given or made by the Corporation, notice by the stockholder to be
timely must be so received by the Secretary not later than the close of business
on the 10th day following the earlier of the day on which the Corporation's
notice of the date of the annual meeting was mailed or the day on which the
Corporation's first public disclosure of the date of the annual meeting was
made.  A stockholder's notice to the Secretary shall set forth as to each matter
the stockholder proposes to bring before the annual meeting (i) a brief
description of the business desired to be brought before the annual meeting and
the reasons for conducting such business at the annual meeting, (ii) the name
and address of the stockholder proposing such business, (iii) the class and
number of shares of the Corporation which are beneficially owned by the
stockholder, and (iv) any material interest of the stockholder in such business.

          Notwithstanding anything in these Bylaws to the contrary, no business
shall be conducted at the annual meeting except in accordance with the
procedures set forth in this Section 12.

          The Chairman of the meeting shall have the authority, if the facts
warrant, to determine that business was not properly brought before the meeting
in accordance with the provisions of this Section 11, and if he should so
determine, he shall so declare to the meeting and any such business not properly
brought before the meeting shall not be transacted.

SECTION 12.  ADVANCE NOTICE OF NOMINEES FOR DIRECTORS.

          Only persons who are nominated in accordance with the following
procedures shall be eligible for election as directors at any meeting of
stockholders.  Nominations of persons for election to the Board of Directors of
the Corporation may be made at an annual meeting of stockholders or at a special
meeting of stockholders as to which the notice of meeting provides for election
of directors, by or under the direction of the Board of Directors, or by any
nominating committee or person appointed by the Board of Directors, or by any
stockholder of the Corporation entitled to vote for the election of directors at
the meeting who complies with the notice procedures set forth in this Section
12.  Such nominations, other than those made by or under the direction of the
Board of Directors or by any nominating committee or person appointed by the
Board of Directors, shall be made pursuant to timely notice in writing to the
Secretary.  To be


<PAGE>


timely, such stockholder's notice shall be delivered to or mailed and received
by the Secretary at the principal executive offices of the Corporation not less
than 20 days nor more than 30 days prior to the meeting; provided, however, that
in the event that less than 30 days' notice or prior public disclosure of the
date of the meeting is given or made by the Corporation, notice by the
stockholder to be timely must be so received by the Secretary no later than the
close of business on the 10th day following the earlier of the day on which the
Corporation's notice of the date of the meeting was mailed or the day on which
the Corporation's first public disclosure of the date of the meeting was made.
Such stockholder's notice shall set forth:  (a) as to each person whom the
stockholder proposes to nominate for election as a director, (i) the name, age,
business address and residence address of the person, (ii) the principal
occupation or employment of the person, (iii) the class and number of shares of
stock of the Corporation which are beneficially owned by the person, and (iv)
any other information relating to the person that is required to be disclosed in
solicitations for proxies for election of directors pursuant to the rules and
regulations under the Securities Exchange Act of 1934; and (b) as to the
stockholder giving the notice, (i) the name and address of the stockholder and
(ii) the class and number of shares of the Corporation which are beneficially
owned by the stockholder.  The Corporation may require any proposed nominee to
furnish such other information as may reasonably be required by the Corporation
to determine the eligibility of such proposed nominee to serve as a director of
the Corporation.  No person shall be eligible for election as a director of the
Corporation unless nominated in accordance with the procedures set forth herein.

          The Chairman of the meeting shall have the authority, if the facts
warrant, to determine that a nomination was not made in accordance with the
foregoing procedure, and if he should so determine, he shall so declare to the
meeting and the defective nomination shall be disregarded.

                                   ARTICLE II

                                    DIRECTORS

SECTION 1.  POWERS.

          The business and affairs of the Corporation shall be managed under the
direction of its Board of Directors.  All powers of the Corporation may be
exercised by or under the authority of the Board of Directors except as
conferred on or reserved to the stockholders by law, by the Charter or by these
Bylaws.  A director need not be a stockholder.  The Board of Directors shall
keep minutes of its meetings and full and fair accounts of its transactions.

SECTION 2.  NUMBER; TERM OF OFFICE.

          The number of directors of the Corporation shall be not less than
three or the same number as the number of stockholders (or one if there is no
stockholder),


<PAGE>


whichever is less; provided, however, that such number may be increased and
thereafter decreased from time to time by vote of a majority of the entire Board
of Directors.  The number of directors shall not exceed eleven (11).  The Board
of Directors shall be divided into three classes, with one class to be elected
at each annual meeting, as provided in the Charter.

SECTION 3.  ANNUAL MEETING; REGULAR MEETINGS.

          As soon as practicable after each annual meeting of stockholders, the
Board of Directors shall meet for the purpose of organization and the
transaction of other business.  No notice of the annual meeting of the Board of
Directors need be given if it is held immediately following the annual meeting
of stockholders and at the same place.  Other regular meetings of the Board of
Directors may be held at such times and at such places, within or without the
State of Maryland, as shall be designated in the notice for such meeting by the
party making the call.  All annual and regular meetings shall be general
meetings, and any business may be transacted thereat.

SECTION 4.  SPECIAL MEETINGS.

          Special meetings of the Board of Directors may be called by the
Chairman of the Board or the President, or by a majority of the directors.

SECTION 5.  QUORUM; VOTING.

          A majority of the Board of Directors shall constitute a quorum for the
transaction of business at every meeting of the Board of Directors; but, if at
any meeting there be less than a quorum present, a majority of those present may
adjourn the meeting from time to time, but not for a period exceeding ten days
at any one time or 60 days in all, without notice other than by announcement at
the meeting, until a quorum shall attend.  At any such adjourned meeting at
which a quorum shall be present, any business may be transacted which might have
been transacted at the meeting as originally called.  Except as hereinafter
provided or as otherwise provided by the Charter or by law, directors shall act
by a vote of a majority of those members in attendance at a meeting at which a
quorum is present.

SECTION 6.  NOTICE OF MEETINGS.

          Notice of the time and place of every regular and special meeting of
the Board of Directors shall be given to each director in the manner provided in
Section 2 of Article IX hereof.  Subsequent to each Board meeting, and as soon
as practicable thereafter, each director shall be furnished with a copy of the
minutes of said meeting.  At least 24 hours' notice shall be given of all
meetings.  The purpose of any meeting of the Board of Directors need not be
stated in the notice.


<PAGE>


SECTION 7.  VACANCIES.

          (a)  If the office of a director becomes vacant for any reason,
including increase in the size of the Board, such vacancy may be filled by the
Board by a vote of a majority of directors then in office, although such
majority is less than a quorum.

          (b)  If the vacancy occurs as a result of the removal of a director,
the stockholders may elect a successor at the meeting at which the removal
occurs.

          (c)  If the entire Board of Directors shall become vacant, any
stockholder may call a special meeting in the same manner that the Chairman of
the Board or the President may call such meeting, and directors for the
unexpired terms may be elected at such special meeting in the manner provided
for their election at annual meetings.

          (d)  A director elected by the Board of Directors to fill a vacancy
shall serve until the next annual meeting of stockholders and until a successor
is elected and qualifies.  A director elected by the stockholders to fill a
vacancy shall serve for the unexpired term and until a successor is elected and
qualifies.

SECTION 8.  RULES AND REGULATIONS.

          The Board of Directors may adopt such rules and regulations for the
conduct of its meetings and the management of the affairs of the Corporation as
it may deem proper and not inconsistent with the laws of the State of Maryland,
these Bylaws and the Charter.

SECTION 9.  EXECUTIVE COMMITTEE.

          The Board of Directors may constitute an Executive Committee, composed
of at least two directors, from among its members.  The Executive Committee
shall hold office at the pleasure of the Board of Directors.  Between sessions
of the Board of Directors, such Committee shall have all of the powers of the
Board of Directors in the management of the business and affairs of the
Corporation, except those powers specifically denied by law.  If any position on
the Executive Committee becomes vacant, or if the number of members is
increased, such vacancy may be filled by the Board of Directors.  The taking of
any action by the Executive Committee shall be conclusive evidence that the
Board of Directors was not in session at the time of such action.  The Executive
Committee shall hold formal meetings and keep minutes of all of its proceedings.
A copy of such minutes shall, after approval by the members of the Committee, be
sent to all directors as a matter of information.  Any action taken by the
Executive Committee within the limits permitted by law shall have the force and
effect of Board action unless and until revised or altered by the Board.  The
presence of not less than a majority of the Committee shall be necessary to
constitute a quorum. Action may be taken without a meeting if a unanimous
written consent is signed by all of the


<PAGE>


members of the Committee, and if such consent is filed with the records of the
Committee.  The Executive Committee shall have the power to elect one of its
members to serve as its Chairman unless the Board of Directors shall have
designated such Chairman.

SECTION 10.  COMPENSATION.

          The directors may receive a stated salary or an attendance fee for
each meeting of the Board of Directors or any committee thereof attended, plus
reimbursement of reasonable expenses of attendance.  The amount of the salary or
attendance fee and any entitlement to reimbursement of expenses shall be
determined by resolution of the Board; provided, however, that nothing herein
contained shall be construed as precluding a director from serving the
Corporation in any other capacity and receiving compensation therefor.

SECTION 11.  PLACE OF MEETINGS.

          Regular or special meetings of the Board may be held within or without
the State of Maryland, as the Board may from time to time determine.  The time
and place of meeting may be fixed by the party calling the meeting.

SECTION 12.  INFORMAL ACTION BY THE DIRECTORS.

          Any action required or permitted to be taken at any meeting of the
Board may be taken without a meeting, if a written consent to such action is
signed by all members of the Board and such consent is filed with the minutes of
the Board.

SECTION 13.  TELEPHONE CONFERENCE.

          Members of the Board of Directors or any committee thereof may
participate in a meeting of the Board or such committee by means of a conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other at the same time.
Participation by such means shall constitute presence in person at the meeting.

                                   ARTICLE III

                                    OFFICERS

officers shall hold office only


<PAGE>


during the pleasure of the Board or until their successors are chosen and
qualify.  Any two of the above offices, except those of President and Vice
President, may be held by the same person, but no officer shall execute,
acknowledge or verify any instrument in more than one capacity when such
instrument is required to be executed, acknowledged or verified by any two or
more officers.  The Board of Directors may from time to time appoint such other
agents and employees with such powers and duties as the Board may deem proper.
In its discretion, the Board of Directors may leave unfilled any offices except
those of President, Treasurer and Secretary.

SECTION 2.  CHAIRMAN OF THE BOARD.

          The Chairman of the Board, if one is elected, shall have the
responsibility for the implementation of the policies determined by the Board of
Directors and for the administration of the business affairs of the Corporation.
The Chairman shall preside over the meetings of the Board and of the
stockholders if present at the meeting.  The Chairman shall be the Chief
Executive Officer of the Corporation if so designated by resolution of the
Board.

SECTION 3.  PRESIDENT.

          The President shall have the responsibility for the active management
of the business and general supervision and direction of all of the affairs of

preside over the meetings of the Board and of the stockholders if present at the
meeting, and shall perform such other duties as may be assigned by the Board of
Directors or the Executive Committee.  The President shall have the authority on
the Corporation's behalf to endorse securities owned by the Corporation and to
execute any documents requiring the signature of an executive officer.  The
President shall perform such other duties as the Board of Directors may direct
and shall be the Chief Executive Officer of the Corporation unless the Chairman
of the Board is so designated by resolution of the Board.

SECTION 4.  VICE PRESIDENTS.

          The Vice Presidents, in the order of priority designated by the Board
of Directors, shall be vested with all the power and may perform all the duties
of the President in the latter's absence.  They may perform such other duties as
may be prescribed by the Board of Directors, the Executive Committee or the
President.

SECTION 5.  TREASURER.

          The Treasurer shall have general supervision over the Corporation's
finances, and shall perform such other duties as may be assigned by the Board of
Directors or the President. Unless the Board designates another officer, the
Treasurer shall be the Chief Financial Officer of the Corporation.  If required
by resolution of the Board, the Treasurer shall furnish a bond (which may be a
blanket bond) with such surety


<PAGE>


and in such penalty for the faithful performance of duty as the Board of
Directors may from time to time require, the cost of such bond to be paid by the
Corporation.

SECTION 6.  SECRETARY.

          The Secretary shall keep the minutes of the meetings of the
stockholders and of the Board of Directors and shall attend to the giving and
serving of all notices of the Corporation required by law or these Bylaws.  The
Secretary shall maintain at all times in the principal office of the Corporation
at least one copy of the Bylaws with all amendments to date, and shall make the
same, together with the minutes of the meeting of the stockholders, the annual
statement of affairs of the Corporation and any voting trust or other

hours.  The Secretary shall perform such other duties as may be assigned by the
Board of Directors.

SECTION 7.  ASSISTANT TREASURER AND SECRETARY.

          The Board of Directors may designate from time to time Assistant
Treasurers and Secretaries, who shall perform such duties as may from time to
time be assigned to them by the Board of Directors or the President.

SECTION 8.  COMPENSATION; REMOVAL; VACANCIES.

          The Board of Directors shall have power to fix the compensation of all
officers of the Corporation.  It may authorize any committee or officer, upon
whom the power of appointing subordinate officers may have been conferred, to
fix the compensation of such subordinate officers.  The Board of Directors shall
have the power at any regular or special meeting to remove any officer if, in
the judgment of the Board, the best interests of the Corporation will be served
by such removal.  The Board of Directors may authorize any officer to remove
subordinate officers.  The Board of Directors may authorize the Corporation's
employment of an officer for a period in excess of the term of the Board.  The
Board of Directors at any regular or special meeting shall have power to fill a
vacancy occurring in any office for the unexpired portion of the term.

SECTION 9.  SUBSTITUTES.

          The Board of Directors may, from time to time in the absence of any
one of its officers or at any other time, designate any other person or persons
on behalf of the Corporation to sign any contracts, deeds, notes or other
instruments in the place or stead of any of such officers, and may designate any
person to fill any one of said offices, temporarily or for any particular
purpose; and any instruments so signed in accordance with a resolution of the
Board shall be the valid act of the Corporation as fully as if executed by any
regular officer.

                                   RESIGNATION

          Any director or officer may resign from office at any time.  Such
resignation shall be made in writing and shall take effect from the time of its
receipt by the Corporation, unless some time be fixed in the resignation, and
then from that date.  The acceptance of a resignation shall not be required to
make it effective.

                                    ARTICLE V

          The seal of the Corporation shall be in the form of two concentric
circles inscribed with the name of the Corporation and the year and State in
which it is incorporated.  The Secretary or Treasurer, or any Assistant
Secretary or Assistant Treasurer, shall have the right and power to attest to
the corporate seal.  In lieu of affixing the corporate seal to any document, it
shall be sufficient to meet the requirements of any law, rule or regulation
relating to a corporate seal to affix the word "(SEAL)" adjacent to the
signature of the person authorized to sign the document on behalf of the
Corporation.

                                  ARTICLE VIII

          Each stockholder shall be entitled to a certificate or certificates
which shall represent and certify the number and class of shares of stock owned
in the Corporation.  Each certificate shall be signed by the Chairman of the
Board, the President or any Vice President and be countersigned by the Secretary
or any Assistant Secretary or the Treasurer or any Assistant Treasurer.  The
signatures of the Corporation's officers and its corporate seal appearing on
stock certificates may be facsimiles if each such certificate is authenticated
by the manual signature of an officer of a duly authorized transfer agent.
Stock certificates shall be in such form, not inconsistent with law and the
Charter, as shall be approved by the Board of Directors.  In case any officer of
the Corporation who has signed any certificate ceases to be an officer of the
Corporation, whether by reason of death, resignation or otherwise, before such
certificate is issued, then the certificate may nevertheless be issued by the
Corporation with the same effect as if the officer had not ceased to be such
officer as of the date of such issuance.

SECTION 2.  TRANSFERS.

          The Board of Directors shall have power and authority to make all such
rules and regulations as the Board may deem expedient concerning the issue,
transfer and registration of stock certificates.  The Board of Directors may
appoint one or more transfer agents and/or registrars for its outstanding stock,
and their duties may be combined.  No transfer of stock shall be recognized or
binding upon the Corporation until recorded on the books of the Corporation, or,
as the case may be, of its transfer agent and/or of its registrar, upon
surrender and cancellation of a certificate or certificates for a like number of
shares.

SECTION 3.  RECORD DATES FOR DIVIDENDS AND STOCKHOLDERS' MEETING.

          The Board of Directors may fix a date not exceeding 90 days preceding
the date of any meeting of stockholders, any dividend payment date or any date
for the allotment of rights, as a record date for the determination of the
stockholders entitled to notice of and to vote at such meeting, or entitled to
receive such dividends or rights, as the case may be, and only stockholders of
record on such date shall be entitled to notice of and to vote at such meeting
or to receive such dividends or rights, as the case may be.  In the case of a
meeting of stockholders, the record date shall be fixed not less than ten days
prior to the date of the meeting.

SECTION 4.  NEW CERTIFICATES.

          In case any certificate of stock is lost, stolen, mutilated or
destroyed, the Board of Directors may authorize the issuance of a new
certificate in place thereof upon such indemnity to the Corporation against loss
and such other terms and conditions as it may deem advisable.  The Board of
Directors may delegate such power to any officer or officers of the Corporation
or to any transfer agent or registrar of the Corporation; but the Board of
Directors, such officer or officers or such transfer agent or registrar may, in
their discretion, refuse to issue such new certificate save upon the order of
some court having jurisdiction.

with such director or officer personally or by telephone facsimile transmission,

shall be consigned to a communication company for delivery shall be deemed to be
the time of the giving of such notice; if mailed, such notice shall be deemed
given 48 hours after the time it is deposited in the mail, postage prepaid.

SECTION 3.  WAIVER OF NOTICE.

          Notice to any stockholder or director of the time, place and/or
purpose of any meeting of stockholders or directors required by these Bylaws may
be dispensed with if such stockholder shall either attend in person or by proxy,

          6.3.2  If at any time it appears that the Subcontractor has not or 
     will not meet the contract delivery schedule, or any extension thereof, 
     the Contractor shall have the right to require the Subcontractor to 
     submit a revised delivery schedule together with adequate information and 
     documentation to support the reasonableness of the proposed schedule.  
     The proposed delivery schedule shall provide a date certain for each 
     deliverable item under the terms of the Subcontract.  Such delivery 
     schedules shall take into consideration all contingencies based upon 
     events or circumstances which are known to the Subcontractor or 
     reasonably forgeable at the time of submission.  The Subcontractor shall 
     submit the revised delivery schedule within twenty-five (25) days after

     Contractor shall have thirty-five (35) days within which to approve or 
     disapprove the Subcontractor's proposed revision to the delivery 
     schedule.  If approved by the Contractor, the proposed delivery schedule 
     shall be incorporated into the Subcontract by bilateral modification.

     If Contractor exercises its right to require a revised delivery schedule 
     and the Subcontractor fails to submit a revised delivery schedule within 
     the time specified above, or any extension thereof granted in writing by 
     the Contractor, the Subcontractor shall be deemed to have failed to make 
     delivery within the meaning of the "Default" clauses of this Subcontract 
     and this Subcontract shall be subject to termination.

          6.3.3  Notwithstanding any other remedies available to the

     supplied hereunder on or by the Delivery Dates specified, Subcontractor 
     shall, at its expense, ship such items in accordance with Contractor's 
     instructions so as to ensure expeditious delivery.

     prior to the delivery dates specified in the purchase order without prior 
     written approval of Contractor's authorized representative.  Early 
     delivery of items required under this Subcontract shall not be deemed to 
     constitute acceptance of 


                                       9


<PAGE>


     accelerated delivery of other items unless such early delivery is

     to the Contractor covering supplies and services under this Subcontract

     services that have been inspected in accordance with the inspection 
     system and have been found by the Subcontractor to be in conformity with 
     the Subcontract requirements.  As part of the system, the Subcontractor 
     shall prepare records evidencing all inspections made under the system

<PAGE>


     Contractor or the Government may perform reviews and evaluations as 
     reasonably necessary to ascertain compliance with this paragraph.  These 
     reviews and evaluations shall be conducted in a manner that will not 
     unduly delay the Subcontract work.  The right of review, whether 
     exercised or not, does not relieve the Subcontractor of the obligations 
     under this Subcontract.

     8.2  Testing Requirements

     Tests or inspections required in the Statement of Work shall demonstrate 
     compliance to all requirements of the statements of work and 
     specifications set forth in the Subcontract.

     and times, including the period of manufacture, and in any event before 
     acceptance.  The Contractor and the Government shall perform inspections 
     or tests in a manner that will not unduly delay the work.  Neither the 
     Contractor nor the Government assume any contractual obligation to 
     perform any inspection and test for the benefit of the Subcontractor 
     unless specifically set forth elsewhere in this Subcontract.

     8.5  Delays to Inspections and Reinspections

          8.5.1  If delays in inspection or test are due to the fault of the 
     Subcontractor and result in additional cost to the Contractor for 
     reinspection or retest, the Contractor may charge to the Subcontractor 
     any reasonable additional costs incurred due to the delay.

          8.5.2  If delays in inspection or test are not due to the fault of 
     the Subcontractor and result in additional cost to the 
     Subcontractor-for)n or retest, the Subcontractor may charge 


                                      13

     delay.

     8.6  Nonconforming Supplies

          8.6.1  The Contractor has the right either to reject or to require 
     correction of nonconforming supplies.  Supplies are nonconforming when 
     they are defective in material or workmanship or are otherwise not in 
     conformity with the Subcontract requirements.  The Contractor may reject 
     nonconforming equipment, supplies and materials with or without 
     disposition instructions.

          8.6.2  The Subcontractor shall remove supplies rejected or required 
     to be corrected.  However, the Contractor may require or permit 
     correction in place, promptly after notice, by and at the expense of the 
     Subcontractor.  The Subcontractor shall not tender for acceptance 
     corrected or rejected supplies without disclosing the former rejection or 
     requirement for correction, and, when required, shall disclose the 
     corrective action taken.

          8.6.3  Subject to the warranty provisions of this Subcontract, if 
     the Subcontractor fails to promptly remove, replace, or correct rejected 
     equipment, materials or supplies that are required to be removed, 
     replaced or corrected, the Contractor may either (1) remove, replace, or 
     correct the supplies and charge the cost to the Subcontractor, or (2) 
     terminate the Subcontract for default.  If the Subcontractor fails to 
     correct or replace the rejected items within the contractual delivery 
     schedule the Contractor has the right to still require delivery and is 
     entitled to an equitable price adjustment.  Failure to agree to an 
     equitable price reduction shall be a Dispute.

          8.6.4  If the Contractor rejects a data item in writing and 
     identifies the specific contract requirement not met and affords the 
     Subcontractor an opportunity to correct, the correction shall be 
     accomplished within 1 0 business days from the date the Subcontractor 
     receives the reason(s) for rejection to the Subcontractor.

     8.7  Nonconforming Services

          8.7.1  Subject to the warranty provisions of this Subcontract, if 
     any of the services do not conform with the Subcontract requirements, the 
     Contractor may require the Subcontractor to perform the services again in 
     conformity with the Subcontract requirements, at no increase in the 
     Subcontract amount.  When the defects in services cannot be corrected by 
     reperformance, the Contractor may (1) require the Subcontractor to take 
     necessary action to ensure that future performance conforms to 
     Subcontract requirements and (2) reduce the Subcontract price to reflect 
     the reduced value of the services performed.

          8.7.2  If the Subcontractor fails to promptly perform the services 
     again or to take the necessary action to ensure future performance in 
     conformity with Subcontract requirements, the Contractor may (1) by 
     contract or otherwise, perform the services and charge to the 
     Subcontractor any cost incurred by the Contractor that is directly 
     related to the performance of such service or (2) terminate the 
     Subcontract for default.

     8.8  Inspection Not a Waiver

          8.8.1  The Contractor's or the Government's failure to inspect and 
     accept or reject the supplies or services shall not relieve the 
     Subcontractor from responsibility, nor impose liability on the Contractor 
     or the Government, for such nonconforming supplies or services.

          8.8.2  Any in-process inspections, reviews, approvals, comments or 
     tests by the Contractor or the Government shall not be deemed to be 
     design approval nor relieve the Subcontractor of responsibility for 
     defects or other failures to meet Subcontract requirements unless set 
     forth in writing and made a part hereof.  All items to be delivered 
     hereunder are subject to final inspection and acceptance as set forth in 
     the Statement of Work hereof.  Acceptance as set forth therein shall be 
     conclusive, except for latent defects, fraud, gross mistakes amounting to 
     fraud, or as otherwise provided in the Subcontract.

          8.8.3  If acceptance is not conclusive for any of the reasons in 
     paragraph 8.8.2 hereof, the Contractor, in addition to any other rights 
     and remedies provided by law, or under other provisions of this 
     Subcontract, shall have the right to require 


                                      15


<PAGE>


     the Subcontractor (1) at no increase in Subcontract price, to correct or 
     replace the defective or nonconforming supplies or services at the point 
     of destination or at the Subcontractors plant, at the Contractor's 
     election, and in accordance with a reasonable delivery schedule as may be 
     agreed upon between the Subcontractor and the Contractor; provided, that 
     the Contractor may require a reduction in Subcontract price if the 
     Subcontractor does not in good faith attempt to meet such delivery 
     schedule, or (2) within a reasonable time after receipt by the 
     Subcontractor of notice of defects or nonconformance, to repay such 
     portion of the Subcontract as is equitable under the circumstances if the 
     Contractor elects not to require correction or replacement.  When 
     supplies or services are returned to the Subcontractor, the Subcontractor 
     shall bear the transportation cost from the point of destination to the 
     Subcontractor's plant and return to the original point of destination.  
     If the Subcontractor fails to perform or act as required in (1) or (2) 
     above and does not cure such failure within a period of ten (10) days (or 
     such longer period as the Contractor may authorize in writing) after 
     receipt of notice from the Contractor specifying such failure, the 
     Contractor shall have the right to replace or correct such supplies or 
     services and charge to the Subcontractor the cost incurred by the 
     Contractor.

2.0  TERMINATION FOR CONVENIENCE OF THE CONTRACTOR (FIXED-PRICE) (FAR 52.249-2) 
     (1984 APR)

     (a)  The Contractor may terminate performance of work under this 
          subcontract in whole or, from time to time, in part, if the 
          Government determines that a termination is in the Government's 
          interest or when is ordered to terminate for the convenience of the 
          Government in accordance with FAR Government, 52.249-02.  The 
          Contractor shall terminate by delivering to the Subcontractor a 
          Notice of Termination specifying the extent of termination and the 
          effective date.

     (b)  After receipt of a Notice of Termination and except as directed by 
          the Contractor, the Subcontractor shall immediately proceed with 
          the following obligations, regardless of any delay in determining 
          or adjusting any amounts due under this clause:

          1.  Stop work as specified in the notice.

          2.  Place no further lower tier subcontracts or orders (referred to 
     as subcontracts in this clause) for materials, services, or facilities 
     except as necessary to complete the continued portion of the Subcontract.

          3.  Terminate all orders or subcontracts to the extent they relate to 
     the work terminated.


                                      25


<PAGE>

          4.  Assign to the Contractor or the Government, as directed by the 
     Contractor, all right, title and interest of the Subcontractor under the 
     subcontracts terminated, in which case the Contractor or the Government 
     shall have the right to settle or to pay any termination settlement 
     proposals arising out of those terminations.

          5.  With approval or ratification to the extent required by the 
     Contractor or the Contracting Officer, settle all outstanding 
     liabilities and termination settlement proposals arising from the 
     termination of subcontracts; the approval or ratification will be final 
     for purposes of this clause.

          6.  As directed by the Contractor, transfer title and deliver to 
     the Contractor or the Government (i) the fabricated or unfabricated 
     parts, work in process, completed work, supplies, and other material 
     produced or acquired for the work terminated, and (ii) the completed or 
     partially completed plans, drawings, information and other property 
     that, if the Subcontract or Prime Contract had been completed, would be 
     required to be furnished to the Contractor or the Government.

          7.  Complete performance of the work not terminated.

          8.  Take any action that may be necessary, or that the Contractor 
     may direct, for the protection and preservation of the property related 
     to this Subcontract that is in the possession of the Subcontractor and 
     in which the Contractor or the Government has or may acquire an interest.

          9.  Use its best efforts to sell, as directed or authorized by the 
     Contractor, any property of the types referred to in subparagraph (6) 
     above; provided, however, that the Subcontractor (i) is not required to 
     extend credit to any purchaser and (ii) may acquire the property under 
     the conditions prescribed by, and at prices approved by, the Contractor 
     and the Contracting Officer.  The proceeds of any transfer or 
     disposition will be applied to reduce any payments to be made by the 
     Contractor under this Subcontract, credited to the price or cost of the 
     work, or paid in any other manner directed by the Contractor.
     (c) After expiration of the plant clearance period as defined in Subpart 
     45.6 of the Federal Acquisition Regulation, the Subcontractor may submit 
     to the Contractor a list, certified as to quantity and quality, of 
     termination inventory not previously 


                                      26


<PAGE>


     disposed of, excluding items authorized for disposition by the 
     Contractor.  The Subcontractor may request the Contractor or the 
     Government to remove those items or enter into an agreement for their 
     storage.  Within 1 5 days, the Contractor or the Government will accept 
     title to those items and remove them or enter into a storage agreement.  
     The Contractor may verify the list upon removal of the items, or if 
     stored, within 45 days from submission of the list, and shall correct 
     the list, as necessary, before final settlement.

     (d)  After termination, the Subcontractor shall submit a final 
     termination settlement proposal to the Contractor in the form and with 
     the certification prescribed by the Contractor.  The Subcontractor shall 
     submit the proposal promptly, but no later than six (6) months from the 
     effective date of termination, unless extended in writing by the 
     Contractor upon written request of the Contractor within this six (6) 
     month period.  However, if the Contractor determines that the facts 
     justify it, a termination settlement proposal may be received and acted 
     on after six months or any extension.  If the Subcontractor fails to 
     submit the proposal within the time allowed, the Contractor may 
     determine, on the basis of information available, the amount, if any, 
     due the Subcontractor because of the termination and shall pay the 
     amount determined.

     (e)  Subject to paragraph (d) above, the Subcontractor and the 
     Contractor may agree upon the whole or any part of the amount to be paid 
     because of the termination.  The amount may include a reasonable 
     allowance for profit on work done.  However, the agreed amount, whether 
     under this paragraph (e) or paragraph (f) below, exclusive of costs 
     shown in subparagraph (f)(3) below, may not exceed the total subcontract 
     price as reduced by (a) the amount of payments previously made, (2) the 
     Subcontract price of work not terminated, and (3) the amount received by 
     the Contractor from the Government for the same termination.  The 
     Subcontract shall be amended, and the Subcontractor paid the agreed 
     amount.  Paragraph (f) below shall not limit, restrict, or affect the 
     amount that may be agreed upon to be paid under this paragraph.

     (f)  If the Subcontractor and the Contractor fail to agree on the whole 
     amount to be paid because of the termination of work, the Contractor 
     shall pay the Subcontractor the amounts determined by the Contractor as 
     follows, but without duplication of any amounts agreed on under 
     paragraph (e) above:


                                      27


<PAGE>


          1.  The subcontract price for completed supplies or services 
     accepted by the Contractor and the Government (or sold or acquired under 
     subparagraph (b)(9) above) not previously paid for, adjusted for any 
     savings of freight and other charges.

          2.  The total of --

              (i)    The costs incurred in the performance of the work 
     terminated, including initial costs and preparatory expenses allocable 
     thereto, but excluding any costs attributable to supplies or services 
     paid or to be paid under subparagraph (f)(1) above;

              (ii)   The cost of settling and paying termination settlement 
     proposals under terminated subcontract that are properly chargeable to 
     the terminated portion of the Subcontract if not included in subdivision 
     (i) above; and

              (iii)  A sum, as profit on subdivision (i) above, determined by 
     the Contracting Officer in determining the Contractor's claim against 
     the Government under 49.202 of the Federal Acquisition Regulation, in 
     effect on the date of this Subcontract, to be fair and reasonable; 
     however, if it appears that the Subcontractor would have sustained a 
     loss on the entire Subcontract had it been completed, the Contractor 
     shall allow no profit under this subdivision (iii) and shall reduce the 
     settlement to reflect the indicated rate of loss.

          3.  The reasonable costs of settlement of the work terminated, 
     including--

              (i)    Accounting, legal, clerical, and other expenses 
     reasonably necessary for the preparation of termination settlement 
     proposals and supporting data;

              (ii)   The termination and settlement of subcontracts 
     (excluding the amounts of such settlements); and

              (iii)  Storage, transportation, and other costs incurred, 
     reasonably necessary for the preservation, protection or disposition of 
     the termination inventory.

     (g)  Except for normal spoilage, and except to the extent that the 
     Contractor or the Government expressly assumed the risk of 


                                      28


<PAGE>


     loss, the Contractor shall exclude from the amounts payable to the 
     Subcontractor under paragraph (f) above, the fair value, as determined 
     by the Contractor, of property that is destroyed, lost, stolen, or 
     damaged so as to become undeliverable to the Contractor, the Government 
     or to a buyer.

     (h)  The cost principles and procedures of Part 31 of the Federal 
     Acquisition Regulation, in effect of the date of this Subcontract, shall 
     govern all costs claimed, agreed to, or determined under this clause.

     (i)  In arriving at the amount due the Subcontractor under this clause, 
     there shall be deducted--

          1.  All unliquidated advance or other payments to the Subcontractor 
     under the terminated portion of this Subcontract;

          2.  Any claim which the Contractor or the Government has against 
     the Subcontractor under this Subcontract.; and

          3.  The agreed price for, or the proceeds of sale of, materials, 
     supplies, or other things acquired by the Subcontractor or sold under 
     the provisions of this clause and not recovered by or credited to the 
     Contractor or the Government.

     (j) the termination is partial, the Subcontractor may file a proposal 
     with the Contractor for an equitable adjustment of the price(s) of the 
     continued portion of the Subcontract.  The Contractor shall make any 
     equitable adjustment agreed upon to the extent the Contractor is also 
     allowed the same equitable adjustment by the Government.  Any proposal 
     by the Subcontractor for an equitable adjustment under this clause shall 
     be requested within sixty (60) days from the effective date of 
     termination unless extended in writing by the Contractor.

     (k) (1)  The Contractor may, under the terms and conditions it 
     prescribes, make partial payments and payments against cost incurred by 
     the Subcontractor for the terminated portion of the Subcontract, if the 
     Contractor believes the total of these payments will not exceed the 
     amount to which the Subcontractor will be entitled.

         (2)  If the total payments exceed the amount finally determined to 
     be due, the Subcontractor shall repay the excess to the Contractor upon 
     demand, together with interest computed 


                                      29


<PAGE>


     at the rate established by the Secretary of the Treasury under 50 U.S.C. 
      APP.  1215 (b)(2).  Interest shall be computed for the period from the 
     date the excess payment is received by the Subcontractor to the date the 
     excess is repaid.  Interest shall not be charged on any excess payment 
     due to a reduction in the Subcontractors termination settlement proposal 
     because of retention or other disposition of termination inventory until 
     10 days after the date of the retention or disposition, or a later date 
     determined by the Contractor because of the circumstances.

     (l)  Unless otherwise provided in this Subcontract or by statute, the 
     Subcontractor shall maintain all records and documents relating to the 
     terminated portion of this Subcontract for four (4) years after final 
     settlement.  This includes all books and other evidence bearing on the 
     Subcontractors costs and expenses under this Subcontract.  The 
     Subcontractor shall make these records and documents available to the 
     Contractor or the Government, at the Subcontractors office, at all 
     reasonable times, without any direct charge.  If approved by the 
     Contractor, photographs, microphotographs, or other authentic 
     reproductions may, be maintained instead of original records and 
     documents.

     the time specified in this Subcontract or any extension;

         (2)  The Contractor's right to terminate this Subcontract under 
     subdivisions (1)(ii) and (1)(iii) above, may be exercised if the 
     Subcontractor does not cure such failure within ten (1 0) days (or more

     not related to the default issues and will be provided in accordance 
     with the terms of this Subcontract.

     (b)  If the Contractor terminates this Subcontract in whole or in part, 
     the Contractor may acquire, under the terms and in the manner the 
     Contractor considers appropriate, supplies or services similar to those 
     terminated, and the Subcontractor will be liable to the Contractor for 
     any excess costs for those supplies or services.  However, the 
     Subcontractor shall continue the work not terminated.

     (c)  Except for defaults of subcontractors at any tier, the 
     Subcontractor shall not be liable for any excess costs if the failure to 
     perform this Subcontract arises from cause beyond the control and 
     without the fault or negligence of the Subcontractor.  Examples of such 
     cause include (1) acts of God, (2) acts of the government in either its 
     sovereign or contractual capacity, (3) fires, (4) floods, (5) epidemics, 
     (6) quarantine restrictions, 171, strikes, (8) freight embargoes, and 
     (9) unusually severe weather.  In each instance the failure to perform 
     must go beyond the control and without the fault or negligence of the 
     Subcontractor.

     (d)  If the failure to perform is caused by the default of a 
     Subcontractor at any tier, and if the cause of the default is beyond the 
     control of both the Subcontractor and lower tier subcontractor, and 
     without the fault or negligence of either, the Subcontractor shall not 
     be liable for any excess costs for failure to perform, unless the 
     subcontracted supplies or services were obtainable from other sources in 
     sufficient time for the Subcontractor to meet the required delivery 
     schedule.

     (e)  If this Subcontract is terminated for default, the Contractor may 
     require the Subcontractor to transfer title and deliver to the 
     Contractor or the Government, as directed by the Contractor, any (1) 
     completed supplies, and (2) partially completed supplies and materials, 
     parts, tools, dies, jigs, fixtures, plans, drawings, information, and 
     contract rights (collectively referred to as "manufacturing materials" 
     in this clause) that the Subcontractor has specifically produced or 
     acquired for the terminated portion of this Subcontract.  Upon direction 
     of the Contractor, the Subcontractor shall also protect and preserve 
     property in its possession in which the Contractor or the Government has 
     an interest.

     (f)  The Contractor shall pay the Subcontract price for completed 
     supplies delivered and accepted.  The Subcontractor and Contractor shall 
     agree on the amount of payment for manufacturing materials delivered and 
     accepted and for the protection and preservation of the property.  
     Failure to agree will be a dispute under the applicable clause of this 
     Subcontract.  The Contractor may withhold from these amounts any sum the 
     Contractor determines to be necessary to protect the Contractor or the 
     Government against loss because of outstanding liens or claims of former 
     lien holders.

     (g)  If, after termination, it is determined that the Subcontractor was 
     not in default, or that the default was excusable, the rights and 
     obligations of the Parties shall be the same as if the termination had 
     been issued for the convenience of the Contractor or the Government.

     (h)  The rights and remedies of the Contractor or the Government in this 
     clause are in addition to any other rights and remedies provided by law 
     or under this Subcontract.

4.0  STOP-WORK ORDER

     4.1  The Contractor may, at any time, by written order to the 
     Subcontractor, require the Subcontractor to stop all, or any part, of 
     the work called for by this Subcontract for a period of 90 days after 
     the stop-work order is delivered to the Subcontractor, and for any 
     further period to which the parties may agree.  The order shall be 
     specifically identified as a stop-work order issued under this clause.  
     Upon receipt of the order, the Subcontractor shall immediately comply 
     with its terms and take all reasonable steps to minimize the incurrence 
     of costs allocable to the work covered by the order during the period of 
     work stoppage.  Within a period of 90 days after a stop-work order is 
     delivered to the Subcontractor, or within any extension of that period 
     to which the parties shall have agreed, the Contractor shall either --

          1.  Cancel the stop-work order; or

          2.  Terminate the work covered by the order as provided in the

     4.2  If a stop-work order issued under this clause is canceled or the 
     period of the order or any extension thereof expires, the Subcontractor 
     shall resume work.  The Contractor shall make an equitable adjustment in 
     the delivery schedule or subcontract price or both, and the Subcontract 
     shall be modified, in writing, accordingly, if --

          1.  The stop-work order results in an increase in the time required 
     for, or in the Subcontractors costs properly allocable to, the 
     performance of any part of this Subcontract; and

          2.  The Subcontractor asserts a claim for the adjustment within 20 
     business days after the end of the period of work stoppage; provided, 
     that, if the Contractor decides the facts justify the action, the 
     Contractor may receive and act upon the claim asserted at any time 
     before final payment under this Subcontract.

     4.3  If a stop-work order is not canceled and the work covered by the 
     order is terminated in accordance with the Termination for Convenience 
     Clause, the Contractor shall allow reasonable costs resulting from the 
     stop-work order in arriving at the termination settlement.

     4.4  If stop-work order is not canceled and the work covered by the 
     order is terminated for default, the Contractor shall allow, by 
     equitable adjustment or otherwise, reasonable costs resulting from the 
     stop-work order.

6.0  VALUE ENGINEERING CHANGE PROPOSALS

     6.1  All VECP's will be in accordance with FAR 52-248-01 (APR 84) as 
     modified by 86 DEV 26.

     Pursuant to 86 DEV 26 -


                                      33


<PAGE>


     (a)  Immediately after subparagraph (b)(3), add the following 
     subparagraph (4).

          (4) Annual acquisition savings, which are the net reduction in 
     acquisition cost to the Government of an item, resulting from an 
     accepted VECP which the Government determines to reduce the quantity 
     requirement on either the instant contract, concurrent and/or future 
     contracts during the sharing period.

     (b)  Delete the definition of "instant unit cost reduction" in 
     subparagraph (b) and substitute the following:

     "Instant unit cost reduction" means the amount of the decrease in unit 
     cost of performance (without deducting any Contractors development or 
     implementation cost) resulting from using the VECP on the instant 
     contract or the amount of savings in annual acquisition cost per unit 
     resulting from the procurement of a reduced total annual demand.  In 
     service contracts, the instant unit cost reduction is normally equal to 
     the number of hours per line item task saved by using the VECP on the 
     instant contract, multiplied by the appropriate contract labor rate.  
     Unit cost reduction for savings in annual acquisition cost will be 
     determined by Old annual demand (OAD) of the old part multiplied by the 
     old unit cost (OUC) minus "new" annual demand (NAD) of the new part 
     multiplied by the new unit cost (NUC) and this quantity divided by the 
     "new" annual demand (NAD) or (OAD)(OUC)-(NAD)(NUC))/(NAD).

     Whenever the Subcontractor submits a Value Engineering Change Proposal 
     (VECP) under the Value Engineering Clause of this subcontract, the 
     proposal, regardless of classification, will be prepared and submitted 
     on DD Form(s) 16921 through -6, in accordance with Appendix A, 
     MIL-STD-480B.  Each Value Engineering Change Proposal submitted will be 
     identified by stamping or printing `VECP' 1/2 inch high at top and 
     bottom of each EGP sheet, with a statement at the top of the ECP Form 
     reading "Value Engineering Change Pursuant to Value Engineering Clause 
     in Section I."

     6.2  No engineering change will be made by the Subcontractor unless he 
     is notified in writing by the Contractor to do so.  The VECP shall be 
     accompanied by an SF 141 1, Contract Pricing Proposal, with sufficient 
     supporting cost details to determine 


                                      34


<PAGE>


     the change in the price of the items and, data items of the Subcontract. 
     If the VECP requires that changes be made to Technical Publication, the 
     changes will be described in the VECP and the supporting cost details 
     will be shown on an SFI 41 1.

     6.3  The Subcontractor shall submit an original and 1 0 copies of the

(ii) enabling the Corporation to attract, retain and reward the best available
persons for positions of substantial responsibility.

     The Plan permits the granting of stock options (including nonqualified
stock options and incentive stock options qualifying under Section 422 of the
Code), stock appreciation rights (including free-standing, tandem and limited
stock appreciation rights), restricted or unrestricted stock awards, phantom
stock, performance awards, or any combination of the foregoing (collectively,
"Awards").

     (a)  PROCEDURE.  The Plan shall be administered by the Committee.

          The Committee shall meet at such times and places and upon such notice
as it may determine.  A majority of the Committee shall constitute a quorum.
Any acts by the Committee may be taken at any meeting at which a quorum is

Additionally, any acts reduced to writing or approved in writing by all of the
members of the Committee shall be valid acts of the Committee.

          Members of the Committee who are either eligible for Awards or have
been granted Awards may vote on any matters affecting the administration of the
Plan or the grant of Awards pursuant to the Plan, except that no such member
shall act upon the granting of an Award to himself or herself, but any such
member may be counted in determining the existence of a quorum at any meeting of
the Committee during which action is taken with respect to the granting of an
Award to him or her.

     (b)  POWERS OF THE COMMITTEE.  The Committee shall have all the powers
vested in it by the terms of the Plan, such powers to include authority, in its
sole and absolute discretion, to grant Awards under the Plan, prescribe Grant
Agreements evidencing such Awards and establish programs for granting Awards.
The Committee shall have full power and authority to take all other actions
necessary to carry out the purpose and intent of the Plan, including, but not

           (ii)  determine the types of Awards to be granted,

     for reference purposes for each Award,

           (iv)  impose such terms, limitations, restrictions and
     conditions upon any such Award as the Committee shall deem
     appropriate,

           (v)  modify, extend or renew outstanding Awards, accept the
     surrender of outstanding Awards and substitute new Awards, provided
     that no such action shall be taken with respect to any outstanding
     Award which would adversely affect the grantee without the grantee's
     consent,

          (vi)  accelerate or otherwise change the time in which an Award
     may be exercised or becomes payable and to waive or accelerate the
     lapse, in whole or in part, of any restriction or condition with
     respect to such Award, including, but not limited to, any restriction
     or condition with respect to the vesting or exercisability of an Award
     following termination of any grantee's employment, and

          (vii)  to establish objectives and conditions, if any, for
     earning Awards and determining whether Awards will be paid after the
     end of a performance period.

The Committee shall have full power and authority to administer and interpret
the Plan and to adopt such rules, regulations, agreements, guidelines and
instruments for the administration of


                                       -3-

<PAGE>


the Plan and for the conduct of its business as the Committee deems necessary or
advisable and to interpret same, all within the Committee's sole and absolute
discretion.

     (d)  LIMITED LIABILITY.  To the maximum extent permitted by law, no member
of the Board or Committee shall be liable for any action taken or decision made
in good faith relating to the Plan or any Award thereunder.

     (e)  INDEMNIFICATION.  To the maximum extent permitted by law, the members
of the Board and Committee shall be indemnified by the Corporation in respect of
all their activities under the Plan.

     (f)  EFFECT OF COMMITTEE'S DECISION.  All actions taken and decisions and
determinations made by the Committee on all matters relating to the Plan
pursuant to the powers vested in it hereunder shall be in the Committee's sole
and absolute discretion and shall be conclusive and binding on all parties
concerned, including the Corporation, its stockholders, any participants in the
Plan and any other employee of the Corporation, and their respective successors
in interest.

4.   SHARES AVAILABLE FOR THE PLAN; MAXIMUM AWARDS

     Subject to adjustments as provided in Section 12 of the Plan, the shares of
stock that may be delivered or purchased or used for reference purposes (with
respect to stock appreciation rights, phantom stock units or performance awards
payable in cash) with respect to Awards granted under the Plan, including with
respect to incentive stock options intended to qualify under Section 422 of the
Code, shall not exceed an aggregate of 2,500,000 shares of Common Stock of the
Corporation.  The Corporation shall reserve said number of shares for Awards
under the Plan, subject to adjustments as provided in Section 12 of the Plan.
If any Award, or portion of an Award, under the Plan expires or terminates
unexercised, becomes unexercisable or is forfeited or otherwise terminated,
surrendered or canceled as to any shares without the delivery of shares of
Common Stock or other consideration, the shares subject to such Award shall
thereafter be shares with respect to which further Awards may be granted under
the Plan.

     The maximum number of shares of Common Stock subject to Awards of any
combination that may be granted during any one calendar year to any one
individual shall be limited to 500,000.  To the extent required by 
Section 162(m) of the Code and so long as Section 162(m) of the Code is 
applicable to persons eligible to participate in the Plan, shares of Common 
Stock subject to the foregoing limit with respect to which the related Award is 
terminated, surrendered or canceled shall not again be available for grant under
this limit.

5.   PARTICIPATION

     Participation in the Plan shall be open to all employees, of the
Corporation, or of any Parent or Subsidiary of the Corporation, as may be
selected by the Committee from time to time.  Notwithstanding the foregoing,
participation in the Plan with respect to Awards of incentive stock options
shall be limited to employees of the Corporation or of any Parent or Subsidiary
of the Corporation.  To the extent necessary to comply with Rule 16b-3 or to
constitute an "outside director" within the meaning of Section 162(m) of the
Code, and only in the event that Rule 16b-3 or Section 162(m) of the Code is
applicable to the Plan or an Award made thereunder, Committee members shall not
be eligible to participate in the Plan while members of the Committee.


                                       -4-

<PAGE>


     Awards may be granted to such eligible persons and for or with respect to
such number of shares of Common Stock as the Committee shall determine, subject
to the limitations in Section 4 of the Plan.  A grant of any type of Award made
in any one year to an eligible person shall neither guarantee nor preclude a
further grant of that or any other type of Award to such person in that year or
subsequent years.

6.   STOCK OPTIONS

     Subject to the other applicable provisions of the Plan, the Committee may
from time to time grant to eligible participants Awards of nonqualified stock
options or incentive stock options as that term is defined in Section 422 of the
Code.  The stock option Awards granted shall be subject to the following terms
and conditions.

     (a)  GRANT OF OPTION.  The grant of a stock option shall be evidenced by a
Grant Agreement, executed by the Corporation and the grantee, stating the number
of shares of Common Stock subject to the stock option evidenced thereby and the
terms and conditions of such stock option, in such form as the Committee may
from time to time determine.

     (b)  PRICE.  The price per share payable upon the exercise of each stock
option ("exercise price") shall be determined by the Committee; provided,
however, that in no event shall the exercise price be less than 100% of the Fair
Market Value of the shares on the date the stock option is granted.

     (c)  PAYMENT.  Stock options may be exercised in whole or in part by
payment of the exercise price of the shares to be acquired in accordance with
the provisions of the Grant Agreement, and/or such rules and regulations as the
Committee may have prescribed, and/or such determinations, orders, or decisions
as the Committee may have made.  Payment may be made in cash (or cash
equivalents acceptable to the Committee) or, unless otherwise determined by the
Committee, in shares of Common Stock or a combination of cash and shares of
Common Stock, or by such other means as the Committee may prescribe.  The Fair
Market Value of shares of Common Stock delivered on exercise of stock options
shall be determined as of the date of exercise.  Shares of Common Stock
delivered in payment of the exercise price may be previously owned shares or, if
approved by the Committee, shares acquired upon exercise of the stock option.
Any fractional share will be paid in cash.  The Corporation may make or
guarantee loans to grantees to assist grantees in exercising stock options.

     If the Common Stock is registered under Section 12(b) or 12(g) of the
Exchange Act, the Committee, subject to such limitations as it may determine,
may authorize payment of the exercise price, in whole or in part, by delivery of
a properly executed exercise notice, together with irrevocable instructions, to:
(i) a brokerage firm designated by the Corporation to deliver promptly to the
Corporation the aggregate amount of sale or loan proceeds to pay the exercise
price and any withholding tax obligations that may arise in connection with the
exercise, and (ii) the Corporation to deliver the certificates for such
purchased shares directly to such brokerage firm.

     (d)  TERMS OF OPTIONS.  The term during which each stock option may be
exercised shall be determined by the Committee; provided, however, that in no
event shall an incentive stock option be exercisable more than ten years from
the date it is granted.  Prior to the exercise of the stock option and delivery
of the shares certificates represented thereby, the grantee shall have none of
the rights of a stockholder with respect to any shares represented by an
outstanding stock option.


                                       -5-

<PAGE>


     (e)  RELOAD OPTIONS.  The terms of a stock option may provide for the
automatic grant of a new stock option Award when the exercise price of the stock
option and/or any related tax withholding obligation is paid by tendering shares
of Common Stock, provided that such automatic replenishment feature shall be
limited to any extent required by rules, regulations, or interpretations under
the Exchange Act with respect to any particular grant of an Award in the case of
a grantee who is or becomes subject to Section 16 of the Exchange Act.  Any
stock option Award which would automatically be granted pursuant to this Section
6(e) without any further Committee action may be exercisable for not more than
the number of shares tendered to exercise the initial stock option and/or to pay
any tax withholding obligation related to such exercise, shall have an exercise
price set at the then Fair Market Value of such shares, and shall have a term
that does not extend beyond the term of the initial stock option.  The Committee
may include such a reload feature in a stock option Award at the time of the
initial grant of the Award or may add such a reload feature to an outstanding
stock option Award as the Committee deems desirable; provided, however, that a
reload feature shall not be added to any outstanding incentive stock option
Award without the consent of the grantee.

     (f)  RESTRICTIONS ON INCENTIVE STOCK OPTIONS.  Incentive stock option
Awards granted under the Plan shall comply in all respects with Code Section 422
and, as such, shall meet the following additional requirements:

          (i)    GRANT DATE.  An incentive stock option must be granted within
     10 years of the earlier of the Plan's adoption by the Board of Directors or
     approval by the Corporation's shareholders.

          (ii)   EXERCISE PRICE AND TERM.  The exercise price of an incentive
     stock option shall not be less than 100% of the Fair Market Value of the
     shares on the date the stock option is granted.  Also, the exercise price
     of any incentive stock option granted to a grantee who owns (within the
     meaning of Section 422(b)(6) of the Code, after the application of the
     attribution rules in Section 424(d) of the Code) more than 10% of the total
     combined voting power of all classes of shares of the Corporation or its
     Parent or Subsidiary corporations (within the meaning of Sections 422 and
     424 of the Code) shall be not less than 110% of the Fair Market Value of
     the Common Stock on the grant date and the term of such stock option shall
     not exceed five years.

          (iii)  MAXIMUM GRANT.  The aggregate Fair Market Value (determined as
     of the Grant Date) of shares of Common Stock with respect to which all
     incentive stock options first become exercisable by any grantee in any
     calendar year under this or any other plan of the Corporation and its
     Parent and Subsidiary corporations may not exceed $100,000 or such other
     amount as may be permitted from time to time under Section 422 of the Code.
     To the extent that such aggregate Fair Market Value shall exceed $100,000,
     or other applicable amount, such stock options shall be treated as
     nonqualified stock options.  In such case, the Corporation may designate
     the shares of Common Stock that are to be treated as stock acquired
     pursuant to the exercise of an incentive stock option by issuing a separate
     certificate for such shares and identifying the certificate as incentive
     stock option shares in the stock transfer records of the Corporation.

          (iv)   GRANTEE.  Incentive stock options shall only be issued to
     employees of the Corporation, or of a Parent or Subsidiary of the
     Corporation.


                                       -6-

<PAGE>


          (v)    DESIGNATION.  No stock option shall be an incentive stock
     option unless so designated by the Committee at the time of grant or in the
     Grant Agreement evidencing such stock option.

     (g)  OTHER TERMS AND CONDITIONS.  Stock options may contain such other
provisions, not inconsistent with the provisions of the Plan, as the Committee
shall determine appropriate from time to time.

7.   STOCK APPRECIATION RIGHTS

     (a)  AWARD OF STOCK APPRECIATION RIGHTS.  Subject to the other applicable
provisions of the Plan, the Committee may at any time and from time to time
grant stock appreciation rights ("SARs") to eligible participants, either on a
free-standing basis (without regard to or in addition to the grant of a stock
option) or on a tandem basis (related to the grant of an underlying stock
option), as it determines.  SARs granted in tandem with or in addition to a
stock option may be granted either at the same time as the stock option or at a
later time; provided, however, that a tandem SAR shall not be granted with
respect to any outstanding incentive stock option Award without the consent of
the grantee.  SARs shall be evidenced by Grant Agreements, executed by the
Corporation and the grantee, stating the number of shares of Common Stock
subject to the SAR evidenced thereby and the terms and conditions of such SAR,
in such form as the Committee may from time to time determine. The term during
which each SAR may be exercised shall be determined by the Committee.  The
grantee shall have none of the rights of a stockholder with respect to any
shares of Common Stock represented by an SAR.

     (b)  RESTRICTIONS OF TANDEM SARS.  No incentive stock option may be
surrendered in connection with the exercise of a tandem SAR unless the Fair
Market Value of the Common Stock subject to the incentive stock option is
greater than the exercise price for such incentive stock option.  SARs granted
in tandem with stock options shall be exercisable only to the same extent and
subject to the same conditions as the stock options related thereto are
exercisable.  The Committee may, in its discretion, prescribe additional
conditions to the exercise of any such tandem SAR.

     (c)  AMOUNT OF PAYMENT UPON EXERCISE OF SARS.  An SAR shall entitle the
grantee to receive, subject to the provisions of the Plan and the Grant
Agreement, a payment having an aggregate value equal to the product of (i) the
excess of (A) the Fair Market Value on the exercise date of one share of Common
Stock over (B) the base price per share specified in the Grant Agreement (which
shall be determined by the Committee but which shall not be less than 100% of
the Fair Market Value of one share of Common Stock on the date of grant of the
SAR), times (ii) the number of shares specified by the SAR, or portion thereof,
which is exercised.  In the case of exercise of a tandem SAR, such payment shall
be made in exchange for the surrender of the unexercised related stock option
(or any portion or portions thereof which the grantee from time to time
determines to surrender for this purpose).

     (d)  FORM OF PAYMENT UPON EXERCISE OF SARS.  Payment by the Corporation of
the amount receivable upon any exercise of an SAR may be made by the delivery of
Common Stock or cash, or any combination of Common Stock and cash, as determined
in the sole discretion of the Committee from time to time.  If upon settlement
of the exercise of an SAR a grantee is to receive a portion of such payment in
shares of Common Stock, the number of shares shall be determined by dividing
such portion by the Fair Market Value of a share of Common Stock on the exercise
date.  No fractional shares shall be used for such payment and the Committee
shall


                                       -7-

<PAGE>


determine whether cash shall be given in lieu of such fractional shares or
whether such fractional shares shall be eliminated.

8.   STOCK AWARDS (INCLUDING RESTRICTED AND UNRESTRICTED SHARES AND PHANTOM
     STOCK)

     (a)  STOCK AWARDS, IN GENERAL.  Subject to the other applicable provisions
of the Plan, the Committee may at any time and from time to time grant stock
Awards to eligible participants in such amounts and for such consideration,
including no consideration or such minimum consideration as may be required by
law, as it determines.  A stock Award may be denominated in shares of Common
Stock or stock-equivalent units ("phantom stock"), and may be paid in Common
Stock, in cash, or in a combination of Common Stock and cash, as determined in
the sole discretion of the Committee from time to time.

     (b)  RESTRICTED SHARES.  Each stock Award shall specify the applicable
restrictions, if any, on such shares of Common Stock, the duration of such
restrictions, and the time or times at which such restrictions shall lapse with
respect to all or a specified number of shares of Common Stock that are part of
the Award.  Notwithstanding the foregoing, the Committee may reduce or shorten
the duration of any restriction applicable to any shares of Common Stock awarded
to any grantee under the Plan.  Share certificates with respect to restricted
shares of Common Stock granted pursuant to a stock Award may be issued at the
time of grant of the stock Award, subject to forfeiture if the restrictions do
not lapse, or upon lapse of the restrictions.  If share certificates are issued
at the time of grant of the stock Award, the certificates shall bear an
appropriate legend with respect to the restrictions applicable to such stock
Award or, alternatively, the grantee may be required to deposit the certificates
with the Corporation during the period of any restriction thereon and to execute
a blank stock power or other instrument of transfer therefor.  Except as
otherwise provided by the Committee, during such period of restriction following
issuance of share certificates, the grantee shall have all of the rights of a
holder of Common Stock, including but not limited to the rights to receive
dividends (or amounts equivalent to dividends) and to vote with respect to the
restricted shares.  If share certificates are issued upon lapse of restrictions
on a stock Award, the Committee may provide that the grantee will be entitled to
receive any amounts per share pursuant to any dividend or distribution paid by
the Corporation on its Common Stock to stockholders of record after grant of the
stock Award and prior to the issuance of the share certificates.

     (c)  PHANTOM STOCK.  The grant of phantom stock units shall be evidenced by
a Grant Agreement, executed by the Corporation and the grantee, that
incorporates the terms of the Plan and states the number of phantom stock units
evidenced thereby and the terms and conditions of such phantom stock units in
such form as the Committee may from time to time determine.  Phantom stock units
granted to a participant shall be credited to a bookkeeping reserve account
solely for accounting purposes and shall not require a segregation of any of the
Corporation's assets.  Phantom stock units may be exercised in whole or in part
by delivery of an appropriate exercise notice to the Committee in accordance
with the provisions of the Grant Agreement, and/or such rules and regulations as
the Committee may prescribe, and/or such determinations, orders, or decisions as
the Committee may make.  Except as otherwise provided in the applicable Grant
Agreement, the grantee shall have none of the rights of a stockholder with
respect to any shares of Common Stock represented by a phantom stock unit as a
result of the grant of a phantom stock unit to the grantee.  Phantom stock units
may contain such other provisions, not inconsistent with the provisions of the
Plan, as the Committee shall determine appropriate from time to time.


                                       -8-

<PAGE>


9.   PERFORMANCE AWARDS

     The Committee may in its discretion grant performance Awards which become
payable on account of attainment of one or more performance goals established by
the Committee.  Performance Awards may be paid by the delivery of Common Stock
or cash, or any combination of Common Stock and cash, as determined in the sole
discretion of the Committee from time to time.  Performance goals established by
the Committee may be based on the Corporation's operating income or one or more
other business criteria selected by the Committee that apply to an individual or
group of individuals, a business unit, or the Corporation as a whole, over such
performance period as the Committee may designate.  The Committee in its
discretion may recommend to the Board of Directors of the Corporation that the
material terms of any performance Award or program with respect to some or all
eligible participants be submitted for approval by the stockholders.

10.  WITHHOLDING OF TAXES

     The Corporation may require, as a condition to the grant of any Award under
the Plan or exercise pursuant to such Award or to the delivery of certificates
for shares issued or payments of cash to a grantee pursuant to the Plan or a
Grant Agreement (hereinafter collectively referred to as a "taxable event"),
that the grantee pay to the Corporation, in cash or, unless otherwise determined
by the Corporation, in shares of Common Stock, including shares acquired upon
grant of the Award or exercise of the Award, valued at Fair Market Value on the
date as of which the withholding tax liability is determined, any federal, state
or local taxes of any kind required by law to be withheld with respect to any
taxable event under the Plan.  The withholding tax obligation that may be paid
by the withholding or delivery of shares may not exceed the statutory minimum
required withholding amount with respect to the grantee's federal, state and
local income tax obligations in connection with a taxable event.  The
Corporation, to the extent permitted or required by law, shall have the right to
deduct from any payment of any kind (including salary or bonus) otherwise due to
a grantee any federal, state or local taxes of any kind required by law to be
withheld with respect to any taxable event under the Plan, or to retain or sell
without notice a sufficient number of the shares to be issued to such grantee to
cover any such taxes.

11.  TRANSFERABILITY

     To the extent required to comply with Rule 16b-3, and in any event in the
case of an incentive stock option or a stock appreciation right granted with
respect to an incentive stock option, no Award granted under the Plan shall be
transferable by a grantee otherwise than by will or the laws of descent and
distribution.  Unless otherwise determined by the Committee in accord with the
provisions of the immediately preceding sentence, an Award may be exercised
during the lifetime of the grantee, only by the grantee or, during the period
the grantee is under a legal disability, by the grantee's guardian or legal
representative.

12.  ADJUSTMENTS; BUSINESS COMBINATIONS

     In the event of a reclassification, recapitalization, stock split, stock
dividend, combination of shares, or other similar event, the maximum number and
kind of shares reserved for issuance or with respect to which Awards may be
granted under the Plan as provided in Section 4 shall be adjusted to reflect
such event, and the Committee shall make such adjustments as it deems
appropriate and equitable in the number, kind and price of shares covered by


                                       -9-

<PAGE>


outstanding Awards made under the Plan, and in any other matters which relate to
Awards and which are affected by the changes in the Common Stock referred to
above.

     In the event of any proposed Change in Control, the Committee shall take
such action as it deems appropriate and equitable to effectuate the purposes of
this Plan and to protect the grantees of Awards, which action may include, but
without limitation, any one or more of the following:  (i) acceleration or
change of the exercise dates of any Award; (ii) arrangements with grantees for
the payment of appropriate consideration to them for the cancellation and
surrender of any Award; and (iii) in any case where equity securities other than
Common Stock of the Corporation are proposed to be delivered in exchange for or
with respect to Common Stock of the Corporation, arrangements providing that any
Award shall become one or more Awards with respect to such other equity
securities.

     The Committee is authorized to make adjustments in the terms and conditions
of, and the criteria included in, Awards in recognition of unusual or
nonrecurring events (including, without limitation, the events described in the
preceding two paragraphs of this Section 12) affecting the Corporation, or the
financial statements of the Corporation or any Subsidiary, or of changes in
applicable laws, regulations, or accounting principles, whenever the Committee
determines that such adjustments are appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under the Plan.

     In the event the Corporation dissolves and liquidates (other than pursuant
to a plan of merger or reorganization), then notwithstanding any restrictions on
exercise set forth in this Plan or any Grant Agreement, or other agreement
evidencing a stock option, stock appreciation right or restricted stock Award:
(i) each grantee shall have the right to exercise his stock option or stock
appreciation right, or to require delivery of share certificates representing
any such restricted stock Award, at any time up to ten (10) days prior to the
effective date of such liquidation and dissolution; and (ii) the Committee may
make arrangements with the grantees for the payment of appropriate consideration
to them for the cancellation and surrender of any stock option, stock
appreciation right or restricted stock Award that is so canceled or surrendered
at any time up to ten (10) days prior to the effective date of such liquidation
and dissolution.  The Committee may establish a different period (and different
conditions) for such exercise, delivery, cancellation, or surrender to avoid
subjecting the grantee to liability under Section 16(b) of the Exchange Act.
Any stock option or stock appreciation right not so exercised, canceled, or
surrendered shall terminate on the last day for exercise prior to such effective
date; and any restricted stock as to which there has not been such delivery of
share certificates or that has not been so canceled or surrendered, shall be
forfeited on the last day prior to such effective date.

13.  TERMINATION AND MODIFICATION OF THE PLAN

     The Board, without further approval of the stockholders, may modify or
terminate the Plan or any portion thereof at any time, except that no
modification shall become effective without prior approval of the stockholders
of the Corporation if stockholder approval is necessary to comply with any tax
or regulatory requirement or rule of any exchange or Nasdaq System upon which
the Common Stock is listed or quoted; including for this purpose stockholder
approval that is required for continued compliance with Rule 16b-3 or
stockholder approval that is required to enable the Committee to grant incentive
stock options pursuant to the Plan.

     The Committee shall be authorized to make minor or administrative
modifications to the Plan as well as modifications to the Plan that may be
dictated by requirements of federal or state laws applicable to the Corporation
or that may be authorized or made desirable by such laws.


                                      -10-

<PAGE>


The Committee may amend or modify the grant of any outstanding Award in any
manner to the extent that the Committee would have had the authority to make
such Award as so modified or amended.

14.  NON-GUARANTEE OF EMPLOYMENT

     Nothing in the Plan or in any Grant Agreement thereunder shall confer any
right on an employee to continue in the employ of the Corporation or shall
interfere in any way with the right of the Corporation to terminate an employee
at any time.

15.  TERMINATION OF EMPLOYMENT

     For purposes of maintaining a grantee's continuous status as an employee
and accrual of rights under any Award, transfer of an employee among the
Corporation and the Corporation's Parent or Subsidiaries shall not be considered
a termination of employment.  Nor shall it be considered a termination of
employment for such purposes if an employee is placed on military or sick leave
or such other leave of absence which is considered as continuing intact the
employment relationship; in such a case, the employment relationship shall be
continued until the date when an employee's right to reemployment shall no
longer be guaranteed either by law or contract.

16.  WRITTEN AGREEMENT

     Each Grant Agreement entered into between the Corporation and a grantee
with respect to an Award granted under the Plan shall incorporate the terms of
this Plan and shall contain such provisions, consistent with the provisions of
the Plan, as may be established by the Committee.

17.  NON-UNIFORM DETERMINATIONS

     The Committee's determinations under the Plan (including without limitation
determinations of the persons to receive Awards, the form, amount and timing of
such Awards, the terms and provisions of such Awards and the agreements
evidencing same) need not be uniform and may be made by it selectively among
persons who receive, or are eligible to receive, Awards under the Plan, whether
or not such persons are similarly situated.

18.  COMPLIANCE WITH SECURITIES LAW

     Common Stock shall not be issued with respect to an Award granted under the
Plan unless the exercise of such Award and the issuance and delivery of share
certificates for such Common Stock pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, the Exchange Act, the rules and regulations promulgated thereunder, and
the requirements of any national securities exchange or Nasdaq System upon which
the Common Stock may then be listed or quoted, and shall be further subject to
the approval of counsel for the Corporation with respect to such compliance to
the extent such approval is sought by the Committee.  All certificates for
Common Stock delivered under the Plan pursuant to any Award or the exercise
thereof shall be subject to such stop transfer orders and other restrictions as
the Committee may deem advisable under the Plan or the rules, regulations, and
other requirements of the Securities and Exchange Commission, any stock exchange
or Nasdaq System upon which such securities are then listed or quoted, and any
applicable Federal or state laws, and the Committee may cause a legend or
legends to be put on any such certificates to make appropriate reference to such
restrictions.


                                      -11-

<PAGE>


19.  NO LIMIT ON OTHER COMPENSATION ARRANGEMENTS

     Nothing contained in the Plan shall prevent the Corporation or its Parent
or Subsidiary corporations from adopting or continuing in effect other
compensation arrangements (whether such arrangements be generally applicable or
applicable only in specific cases) as the Committee in its discretion determines
desirable, including without limitation the granting of stock options, stock
awards, stock appreciation rights or phantom stock units otherwise than under
the Plan.

20.  NO TRUST OR FUND CREATED

     Neither the Plan nor any Award shall create or be construed to create a
trust or separate fund of any kind or a fiduciary relationship between the
Corporation and a grantee or any other person.  To the extent that any grantee
or other person acquires a right to receive payments from the Corporation
pursuant to an Award, such right shall be no greater than the right of any
unsecured general creditor of the Corporation.

21.  GOVERNING LAW

     The validity, construction and effect of the Plan, of Grant Agreements
entered into pursuant to the Plan, and of any rules, regulations, determinations
or decisions made by the Board or Committee relating to the Plan or such Grant
Agreements, and the rights of any and all persons having or claiming to have any
interest therein or thereunder, shall be determined exclusively in accordance
with applicable federal laws and the laws of the State of Maryland, without
regard to its conflict of laws rules and principles.

22.  PLAN SUBJECT TO CHARTER AND BY-LAWS

     This Plan is subject to the Charter and By-Laws of the Corporation, as they
may be amended from time to time.

23.  EFFECTIVE DATE; TERMINATION DATE

     The Plan is effective as of the date on which the Plan is adopted by the
Board, subject to approval of the stockholders within twelve months before or
after such date.  No Award shall be granted under the Plan after the close of
business on the day immediately preceding the tenth anniversary of the effective
date of the Plan.  Subject to other applicable provisions of the Plan, all
Awards made under the Plan prior to such termination of the Plan shall remain in
effect until such Awards have been satisfied or terminated in accordance with
the Plan and the terms of such Awards.
