                                    SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and Financial Statements and Notes thereto appearing elsewhere in
this Prospectus. This Prospectus contains forward-looking statements that
involve risks and uncertainties. The Company's actual results could differ
materially from the results discussed in the forward-looking statements. Factors
that could cause or contribute to such differences include those discussed under
"Risk Factors," as well as those discussed elsewhere in this Prospectus. Certain
terms used herein are defined under the heading "Glossary of Terms."
 
                                  THE COMPANY
 
     SCC is the leading provider of 9-1-1 operations support systems ("OSS")
services to incumbent local exchange carriers ("ILECs"), competitive local
exchange carriers ("CLECs") and wireless carriers in the United States. The
Company has redefined the U.S. market for 9-1-1 OSS by creating the first and
largest 9-1-1 service bureau, the SCC National Data Services Center ("NDSC"),
with over 70 million subscriber data records under management throughout North
America. The Company manages the data that enable a 9-1-1 call to be routed to
the appropriate public safety agency along with accurate and timely information
about the caller's identification and location. Through SCC's NDSC, the Company
offers a comprehensive, cost-effective solution to the 9-1-1 service
provisioning needs of ILECs, CLECs and wireless carriers by enabling them to
outsource virtually all aspects of the operations of their 9-1-1 data management
services, including system activation, routine data administration, event
transaction processing and performance management, with a high level of security
and survivability. In addition, the Company licenses its 9-1-1 OSS software to
carriers that wish to manage the delivery of 9-1-1 data management services
in-house. Representative carriers using SCC's 9-1-1 OSS solution include
Ameritech, AT&T Wireless Services, BellSouth, MCI, Sprint PCS and Worldcom
Network SVCS.
 
     Today, 9-1-1 is a fundamental element of local exchange service and
carriers' OSS infrastructure. 9-1-1 service involves the routing of emergency
calls to the appropriate public safety answering point ("PSAP") responsible for
dispatching police, fire and other emergency services. When a caller dials
9-1-1, information about the caller's location, telephone number and the
jurisdictionally appropriate PSAP must be quickly accessed from carriers'
network and mission-critical data servers. Thus, delivery of 9-1-1 service
presents a difficult OSS challenge for carriers because it requires the
coordination of data from multiple sources, the review and processing of the
data, the resolution of data errors and conflicts, and the insertion of the data
into network and mission-critical data servers. ILECs, CLECs and wireless
carriers require a 9-1-1 solution that addresses these OSS challenges and cost
effectively provides a high degree of data integrity and reliability, allows
them to comply with regulatory mandates, and addresses their need to provide
additional value-added services. ILECs are seeking to reduce the significant
capital expenditures associated with supporting rapidly evolving 9-1-1
infrastructure and upgrading their 9-1-1 data management and network control
services to meet PSAP requirements and technological advancements. CLECs and
wireless carriers, many of which are relatively small and new to the markets in
which they are now competing, are seeking to increase their own subscriber bases
while minimizing their investment in OSS technology infrastructure and
personnel, as well as the relationships with PSAPs necessary to provide 9-1-1
service. Carriers with these requirements may choose to develop their own
proprietary solutions, to license the 9-1-1 software and manage the delivery of
9-1-1 service themselves, or to outsource their 9-1-1 OSS needs.
 
     Through SCC's NDSC, the Company provides the data management services that
ILECs, CLECs and wireless carriers need to deliver 9-1-1 calls to the
appropriate PSAP, along with critical information such as caller location and
call-back number that PSAPs need to respond effectively to emergencies. Complex
data screening and preparation are completed to initialize properly the
underlying systems necessary for 9-1-1 call routing and information display for
the call taker. SCC's NDSC frequently receives and processes electronic
transmissions from ILECs, CLECs and wireless carriers detailing subscriber and
coverage updates and public safety jurisdiction boundary changes from PSAPs.
Records identified as potentially having problems are automatically separated
for manual review and analysis by SCC data integrity analysts. Using the updated
 
                                        4
<PAGE>   7
 
information, SCC's 9-1-1 OSS then provides the information to route the 9-1-1
call and transmit essential information to the emergency service provider.
 
     The Company's objective is to be the leading national provider of 9-1-1 OSS
and other complementary services to ILECs, CLECs and wireless carriers. SCC
focuses on developing innovative and automated solutions to provide customers
with a comprehensive system for managing large amounts of dynamic subscriber
information. Key elements of the Company's strategy are to: (i) maintain and
extend its leadership position in the 9-1-1 wireline data management market;
(ii) capitalize on emerging wireless carrier opportunities; (iii) maintain and
extend its leadership position in national clearinghouse services; (iv) provide
additional services to telecommunications carriers; (v) develop applications for
new commercial products; and (vi) expand international operations.
 
     The Company was incorporated in July 1979 in the State of Colorado under
the name of Systems Concepts of Colorado, Inc., and was reincorporated in
September 1993 in the State of Delaware under the name SCC Communications Corp.

                                  RISK FACTORS
 
     An investment in the shares of Common Stock offered hereby involves a high
degree of risk. The following factors, in addition to the other information
contained in this Prospectus, should be carefully considered in evaluating the
Company and its business before purchasing shares of the Common Stock offered
hereby. This Prospectus contains forward-looking statements that involve risks
and uncertainties. The Company's actual results may differ significantly from
the results discussed in the forward-looking statements. Factors that could
cause or contribute to such differences include, but are not limited to, those
discussed below as well as that discussed elsewhere in this Prospectus.
 
SIGNIFICANT FLUCTUATIONS IN QUARTERLY RESULTS OF OPERATIONS
 
     The Company has experienced fluctuations in its quarterly operating results
and anticipates that such fluctuations will continue and could intensify.
Fluctuations in operating results may result in volatility in the price of the
Company's Common Stock. Although the Company was profitable in seven of its last
eight quarters, there can be no assurance that the Company's profitability will
continue in the future or, if the Company is profitable, that its levels of
profitability will not vary significantly between quarters.
 
   
     The Company experienced a net loss of approximately $453,000 in 1997,
exclusive of the benefit for income taxes, as a result of losses from
discontinued operations of approximately $876,000 and losses on the disposal of
such operations of approximately $2.0 million. The Company's operating results
may fluctuate as a result of many factors, including the length of the sales
cycle for new or existing customers, the size, timing or duration of significant
customer contracts, fluctuations in the number of subscriber records under
management, timing of new service offerings, demand by license customers for new
development services, customer acceptance of service offerings, ability of the
Company to hire, train and retain qualified personnel, increased competition,
changes in operating expenses, changes in the Company's strategy, the financial
performance of the Company's customers, changes in telecommunications
legislation and regulations that may affect the competitive environment for the
Company's services, and general economic factors. The Company's contracts for
data management services generally include a non-recurring initial fee, and
therefore, the Company may recognize significantly increased revenue for a short
period of time upon commencing services for a new customer.
    
 
     The Company's expense levels are based in significant part on its
expectations regarding future revenue. The Company's revenue is difficult to
forecast because the market for the Company's services is evolving rapidly and
the length of the Company's sales cycle, the size and timing of significant
customer contracts and license fees and the timing of recognition of
non-recurring initial fees vary substantially among customers. Accordingly, the
Company may be unable to adjust spending in a timely manner to compensate for
any unexpected shortfall in revenue. Any significant shortfall could therefore
have a material adverse effect on the Company's business, financial condition
and results of operations. In addition, the Company hired a significant number
of employees in 1996, 1997 and the first quarter of 1998, and expects to
continue hiring additional employees during the remainder of 1998. The Company
expects that this increase will affect the Company's operating margins for the
short term. There can be no assurance that the Company can continue to report
operating profits, and failure to do so could have a material adverse effect on
the Company's business, financial condition and results of operations.
 
     Based on all of the foregoing, the Company believes that future revenue,
expenses and operating results are likely to vary significantly from quarter to
quarter. As a result, quarter-to-quarter comparisons of operating results are
not necessarily meaningful or indicative of future performance. Furthermore, it
is possible that in some future quarter the Company's operating results will be
below the expectations of public market analysts or investors. In such event, or
in the event that adverse conditions prevail, or are perceived to prevail, with
respect to the Company's business or generally, the market price of the
Company's Common Stock would likely be materially adversely affected. See
"Selected Financial Data" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

LENGTHY SALES CYCLE
 
     Potential customers of the Company typically commit significant resources
to the technical evaluation of the Company's services and products and the
Company typically spends substantial time, effort and money providing education
regarding the Company's 9-1-1 OSS solution. The evaluation process often results
in an extensive and lengthy sales cycle, typically ranging between six months
and two years, making it difficult for the Company to forecast the timing and
magnitude of sales contracts. Delays associated with customers' internal
approval and contracting procedures, procurement practices, and testing and
acceptance processes are common. For example, customers' budgetary constraints
and internal acceptance reviews may cause potential customers to delay or forego
a purchase. The delay or failure to complete one or more large contracts could
have a material adverse effect on the Company's business, financial condition
and results of operations and cause the Company's operating results to vary
significantly from quarter to quarter. See "-- Significant Fluctuations in
Quarterly Results of Operations" and "Business -- Sales and Marketing."
 
RELIANCE ON SIGNIFICANT CUSTOMERS
 
   
     The Company historically has depended on, and expects to continue to depend
on, large contracts from a limited number of significant customers. During the
year ended December 31, 1996, the Company recognized approximately 82% of its
total revenue from continuing operations from Ameritech and U.S. WEST, each of
which accounted for greater than 10% of the Company's revenue in such year.
During the year ended December 31, 1997, the Company recognized approximately
81% of its total revenue from continuing operations from Ameritech, BellSouth
Inc. and U.S. WEST, each of which accounted for greater than 10% of the
Company's revenue in such year. The Company believes that these customers will
continue to represent a substantial portion of the Company's total revenue in
the future. Certain of the Company's contracts with these customers allow them
to cancel their contracts with the Company in the event of changes in
regulatory, legal, labor or business conditions. The Company's contracts with
these customers expire between 2004 and 2005. The loss of any of these customers
would have a material adverse effect on the Company's business, financial
condition and results of operations. Recently SBC Communications, Inc., which is
not a customer of the Company, agreed to acquire Ameritech. The Company cannot
predict what effect, if any, this acquisition will have on the Company and there
can be no assurance that this acquisition or any future consolidation in the
telecommunications industry will not have a material adverse effect on the
Company's business, financial condition and results of operation. None of the
Company's major customers has any obligation to purchase additional products or
additional services beyond those currently contemplated by their existing
contracts. Consequently, the failure by the Company to develop relationships
with significant new customers could have a material adverse effect on the rate
of growth in the Company's revenue, if any. If the Company fails to monitor and
maintain adequately the quality and expand the breadth of its services and
products, advance its technology or continue to price its services and products
competitively, one or more of its major customers may select alternative
providers or seek to develop services and products internally. See "Business --
Customers."
    
 
RATE OF ADOPTION BY PUBLIC SAFETY ANSWERING POINTS
 
     A growing percentage of the Company's revenue is derived from the
management of 9-1-1 data records for wireless carriers. Recognizing the public
safety need for improved wireless 9-1-1 service, the Federal Communications
Commission (the "FCC") issued Report & Order 94-102 (the "Order") on June 12,
1996, a directive that mandated the adoption of 9-1-1 technology by wireless
carriers in two phases. Phase I required wireless carriers to provide to
requesting PSAPs at the time of a 9-1-1 call, the caller's telephone number and
location of the receiving cell site. Wireless carriers had to comply with Phase
I mandates by the later of April 1, 1998, or six months after the PSAP request.
Phase II requires wireless carriers to locate a 9-1-1 caller to within 125
meters, subject to FCC guidelines. Wireless carriers must comply with Phase II
mandates for requesting PSAPs by October 1, 2001. The Company believes that the
technological challenges confronting wireless carriers attempting to comply with
the Order will encourage them to outsource their 9-1-1 services. If many
wireless carriers decide not to outsource such services, the Company's business,
financial condition and results of operations could be materially and adversely
affected. If PSAPs delay demanding services complying
 
                                        8
<PAGE>   11
 
with the Order from wireless carriers, the Company would experience a delay in
receiving revenue under its current wireless contracts that, because the Company
has already incurred costs in expectation of such revenue, could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
DEPENDENCE ON NEW PRODUCTS AND SERVICES; RAPID TECHNOLOGICAL CHANGE
 
     The market for the Company's services is characterized by rapid
technological change, frequent new product or service introductions, evolving
industry standards and changing customer needs. The Company currently intends to
begin offering in late 1998 both its Subscriber ALI product, which will allow
subscribers to enter personal information into their 9-1-1 records, and its
Emergency Warning and Evacuation System, which will allow PSAPs to call all
numbers in a given area and warn of imminent danger. The introduction of
products and services embodying new technologies and the emergence of new
industry and technology standards can render existing products and services
obsolete and unmarketable in short periods of time. The Company expects other
vendors regularly to introduce new products and services, as well as
enhancements to their existing products and services, that will compete with the
services and products offered by the Company. As a result, the life cycles of
the Company's services and products are difficult to estimate. The Company
believes that its future success will depend in large part on its ability to
maintain and enhance its current service and product offerings, to develop and
introduce regularly new services and products that will keep pace with
technological advances and satisfy evolving customer requirements, and to
achieve acceptable levels of sales of its new services and products through its
current customers that resell the Company's solutions to their subscribers.
However, there can be no assurance that the Company will not experience
difficulties that could delay or prevent the successful development,
introduction or marketing of such new services and products or that its new
services and products will adequately meet the requirements of the marketplace
and achieve market acceptance. Announcements of currently planned or other new
service and product offerings by the Company or its competitors may cause
customers to defer the purchase of existing Company services and products. The
Company's inability to develop on a timely basis new services or products, or
the failure of such new services or products to achieve market acceptance, could
have a material adverse effect on the Company's business, financial condition
and results of operations. The development of new, technologically advanced
products and services is a complex and uncertain process requiring high levels
of innovation, as well as the accurate anticipation of technological and market
trends. There can be no assurance that the Company will successfully develop,
introduce or manage the transition to new services and products. Furthermore,
services and products such as those offered by the Company may contain
undetected or unresolved errors when they are first introduced or as new
versions are released. There can be no assurance that, despite extensive testing
by the Company, errors will not be found in new services and products after
commencement of commercial availability, resulting in delay in or loss of market
acceptance and sales, diversion of development resources, injury to the
Company's reputation or increased service and warranty costs, any of which could
have a material adverse effect on the Company's business, financial condition
and results of operations. Significant delays in meeting deadlines for announced
service or product introductions or performance problems with such products or
upgrades could result in an undermining of customer confidence in the Company's
services and products, which would materially adversely affect its customer
relationships as well.
 
     In addition, the Company plans to introduce transaction-based services and
software products to industries different from those the Company has
traditionally supported. There can be no assurance that the Company will be
successful in developing and marketing these new services and products or that
its current or new services and products will adequately meet the demands of its
new markets. Because it is generally not possible to predict the time required
and costs involved in reaching certain research, development and engineering
objectives related to entering new markets, actual development costs could
exceed budgeted amounts and estimated development schedules could require
extensions. Furthermore, there can be no assurance that the Company will not
experience difficulties that could delay or prevent the successful development,
introduction and marketing of these services and products. If the Company is
unable to develop and introduce new services and products to these new markets
in a timely manner, or if a new release of a product or service to such new
markets does not achieve market acceptance, the Company's business, financial
condition and results of operations could be materially adversely affected.

<PAGE>   12
 
DEPENDENCE ON A SINGLE SERVICE OFFERING; SUSTAINABILITY OF GROWTH
 
     The Company currently derives substantially all of its revenue from the
provision of its 9-1-1 OSS solution to ILECs, CLECs and wireless carriers.
Accordingly, the Company is susceptible to adverse trends affecting this market
segment, such as government regulation, technological obsolescence and the entry
of new competition. The Company expects that this market will continue to
account for substantially all of its revenue in the near future. As a result,
the Company's future success will depend on its ability to continue to sell its
9-1-1 OSS solution to ILECs, CLECs and wireless carriers, maintain and increase
its market share by providing other value-added services to the market, and
successfully adapt its technology and services to other related markets. There
can be no assurance that markets for the Company's existing services and
products will continue to expand or that the Company will be successful in its
efforts to penetrate new markets. See "Business -- Strategy."
 
FIXED PRICE CONTRACTS AND OTHER PROJECT RISKS
 
     During 1997, approximately 75% of the Company's revenue was generated on a
fixed price per subscriber basis. The Company generally enters into contracts
with a ten-year term for wireline data management services and with a
two-to-five-year term for wireless data management services for which the
Company generally receives a fixed monthly fee based upon the number of
subscribers and upon the services selected by the customer. Therefore, the
Company's failure to estimate accurately the resources required for a fixed
price per subscriber contract could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Overview."
 
     The Company provides 9-1-1 OSS services that are critical to the public's
perception of its customers. The Company's failure to meet a customer's
expectations in the performance of its services could damage the Company's
reputation and adversely affect its ability to attract new business, and may
have a material adverse effect upon its business, financial condition and
results of operations. The Company has undertaken, and in the future may
undertake, projects in which the Company guarantees performance based upon
defined operating specifications. Unsatisfactory performance may result in
client dissatisfaction and a reduction in payment to, or payment of damages by,
SCC, any of which could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     Because the Company's services and products are utilized by its customers
to provide critical 9-1-1 services, the provision of services and licensing of
software by the Company may entail the risk of product liability and related
claims. The Company's agreements with its customers typically require the
Company to indemnify its customers for the Company's own acts of negligence. The
Company currently has product liability insurance that, subject to liability
limitations and customary exclusions, covers claims resulting from the failure
of the Company's services or products to perform the function or serve the
purpose intended. To the extent that any claims are not covered by such
insurance, the Company's business, financial condition and results of operations
may be materially and adversely affected by a successful product liability
claim.
 
EMERGING TELECOMMUNICATIONS MARKET AND NEW CARRIERS; REGULATORY UNCERTAINTY
 
     The Company provides its 9-1-1 OSS solution to telecommunications carriers
in the wireline and wireless markets. Although these markets have experienced
significant growth and have been characterized by increased deregulation and
competition in recent years, there can be no assurance that such trends will
continue at similar rates or that the Company will be able to market and sell
effectively its products and services in such markets. In addition, many of the
new entrants in the telecommunications market are companies that lack
significant financial and other resources. To cultivate relationships with such
new market entrants, the Company may be required to offer alternative pricing
arrangements, which may provide for deferred payments. However, there can be no
assurance that the Company will be able to develop such relationships or that
new carriers that become customers of the Company will gain market acceptance
for their telecommunications services. If the Company permits customers that do
not have adequate financial resources to pay the Company for its services on a
deferred basis, the Company ultimately may be unable to collect
 
                                       10
<PAGE>   13
 
payments for such services. Because the Company historically has depended on a
limited number of long-term customer relationships, the failure of the Company
to develop relationships with, make sales to, or collect payments from new
telecommunications carriers, or the failure of the Company's customers to
compete effectively in the telecommunications market, could have a material
adverse effect on the Company's business, financial condition and results of
operations. In addition, the telecommunications industry is experiencing
substantial consolidations and changes that are unpredictable, and any such
consolidation or change could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     9-1-1 services generally are funded by a locally imposed fee per subscriber
per month. A portion of this tax is paid to the local carrier providing the
9-1-1 services. The Company generally receives a monthly fee per subscriber from
its customers for management of 9-1-1 data records, allowing the carrier to
match its fixed revenue stream for 9-1-1 services with a fixed cost for record
management. Changes by local governments in the funding mechanism for 9-1-1
services or the parties responsible for the provision of such services could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
     The market for the Company's services and products has been influenced by
the adoption of regulations under the Telecommunications Act of 1996 (the "1996
Act"), the new duties imposed on ILECs by the 1996 Act to open the local
telephone markets to competition, and the new requirements imposed on wireless
carriers by the Order. Therefore, any changes to such legal requirements, the
adoption of new regulations by federal or state regulatory authorities under the
1996 Act or any legal challenges to the 1996 Act could have a material adverse
effect upon the market for the Company's services and products. Although the
1996 Act was designed to expand competition in the telecommunications industry,
the realization of the objectives of the 1996 Act is subject to many
uncertainties, including judicial and administrative proceedings designed to
define rights and obligations pursuant to the 1996 Act, actions or inactions by
ILECs and other carriers that affect the pace at which changes contemplated by
the 1996 Act occur, resolution of questions concerning which parties will
finance such changes, and other regulatory, economic and political factors.
 
     The Company is aware of certain litigation challenging the validity of the
1996 Act and the local telephone competition rules adopted by the FCC to
implement the 1996 Act. The U.S. Eighth Circuit Court of Appeals has invalidated
the pricing methodology and unbundling requirements adopted by the FCC while
upholding a portion of the FCC's local competition rules, and both the U.S.
federal government and ILECs have filed petitions for review with the U.S.
Supreme Court. In a recent decision, a U.S. District Court in Texas declared
unconstitutional the provisions of the 1996 Act requiring the Regional Bell
Operating Companies (the "RBOCs") to comply with certain conditions, including
local number portability ("LNP"), in order to receive regulatory approval to
enter long distance markets. The U.S. Department of Justice, representing the
FCC, has appealed this decision. Such litigation may serve to delay
implementation of the 1996 Act, which could adversely affect demand for the
Company's services and products. Any delays in the deadlines imposed by the 1996
Act, the FCC or the Order, or any invalidation, repeal or modification in the
requirements imposed by the 1996 Act, the FCC or the Order, could have a
material adverse effect on the Company's business, financial condition and
results of operations. Moreover, customers may require, or the Company otherwise
may deem it necessary or advisable, that the Company modify its services and
products to address actual or anticipated changes in the regulatory environment.
Any other delays in implementation of the 1996 Act, or other regulatory changes,
could materially adversely affect the Company's business, financial condition
and results of operations.
 
RISK OF SYSTEM FAILURES
 
     The Company's operations are dependent upon its ability to maintain its
computer and telecommunications equipment and systems in effective working
order, and to protect its systems against damage from fire, natural disaster,
power loss, telecommunications failure or similar events. Although all of the
Company's mission-critical systems and equipment are designed with built-in
redundancy and security, there can be no assurance that a fire, natural
disaster, power loss, telecommunications failure or similar event would not
result in an interruption of the Company's services. Any damage, failure or
delay that causes interruptions in the Company's operations could have a
material adverse effect on the Company's business, financial condition and
results of operations. Furthermore, any future addition or expansion of the
Company's facilities to increase
 
                                       11
<PAGE>   14
 
capacity could increase the Company's exposure to damage from fire, natural
disaster, power loss, telecommunications failure or similar events. There can be
no assurance that the Company's property and business interruption insurance
will be adequate to compensate the Company for any losses that may occur in the
event of a system failure or that such insurance will continue to be available
to the Company at all or, if available, that it will be available on
commercially reasonable terms. See "Business -- Products and Services."
 
MANAGEMENT OF CHANGE
 
     The Company has expanded its operations rapidly over the past several
years, placing significant demands on its administrative, operational and
financial personnel and systems. Additional expansion by the Company may further
strain its management, operational, financial reporting, and other systems and
resources. There can be no assurance that the Company's systems, resources,
procedures, controls and existing space will be adequate to support such
expansion of the Company's operations. The Company's future operating results
will depend substantially on the ability of its officers and key employees to
manage changing business conditions and to implement and improve its management,
operational, financial control and other reporting systems. In addition, the
Company's future operating results depend on its ability to attract, train and
retain qualified consulting, technical, sales, financial, marketing and
management personnel. Failure to hire, train or retain qualified personnel
necessary to keep pace with the Company's development of products and services
could have a material adverse effect on the Company's business, financial
condition and results of operations. Continued expansion will require the
Company's management to: enhance management information and reporting systems;
standardize implementation methodologies of SCC's NDSC; further develop its
infrastructure; and continue to maintain customer satisfaction. If the Company
is unable to respond to and manage changing business conditions, the quality of
the Company's products and services, its ability to retain key personnel and its
business, financial condition and results of operation could be materially
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Management."
 
HIGHLY COMPETITIVE MARKET; COMPETITION
 
     The market for 9-1-1 OSS solutions is intensely competitive and the Company
expects competition to increase in the future. The Company believes that the
principal competitive factors affecting the market for 9-1-1 OSS services
include flexibility, reliability, manageability, technical features, wireless
support, performance, ease of use, price, scope of product offerings, and
customer service and support. Although the Company believes that its solution
competes favorably with respect to such factors, there can be no assurance that
the Company can maintain its competitive position against current and potential
competitors, especially those with significantly greater financial, marketing,
support service, technical and other competitive resources.
 
     The Company's principal competitors generally fall within one of three
categories: internal development departments of major carriers or consulting
firms that support such departments; relatively smaller companies that offer
applications with limited scope; and larger companies that are either in the
process of entering the Company's market or have the potential to develop
products and services that compete with the Company's service offerings.
 
     A number of companies currently market or have under development software
products and services to provide 9-1-1 administration. The Company competes with
a few smaller companies, including XYPoint Corporation, for the provision of
9-1-1 data management services to wireless carriers, although the Company
expects more significant competition in the future. Mergers or consolidations
among these competitors or acquisitions of these companies by larger competitors
would make them more formidable competitors to the Company. There can be no
assurance that the Company's current and potential competitors will not develop
products and services that may be more effective than the Company's current or
future 9-1-1 solutions or that the Company's technologies and offerings will not
be rendered obsolete by such developments.
 
     Finally, there are a number of companies that market and sell various
products and services to telecommunications carriers, such as billing software
and advanced telecommunications equipment, that have been broadly adopted by the
Company's customers and potential customers. In addition, vendors of
 
                                       12
<PAGE>   15
 
telecommunications software and hardware in the future may enhance their
products to include functionality that is currently provided by the Company's
solutions. The widespread inclusion of the functionality of the Company's
service offerings as standard features of other telecommunications software or
hardware could render the Company's services obsolete and unmarketable,
particularly if the quality of such functionality were comparable to that of the
Company's services. Furthermore, even if the 9-1-1 functionality provided as
standard features by telecommunications software or networking hardware is more
limited than that of the Company's services, there can be no assurance that a
significant number of customers would not elect to accept more limited
functionality in lieu of purchasing additional products or services. For
example, Lucent Technologies offers carriers software systems with functionality
similar to the Company's services. Many of these larger companies have longer
operating histories, greater name recognition, access to larger customer bases
and significantly greater financial, technical and marketing resources than the
Company. As a result, they 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 and services, than the
Company. If these companies were to introduce products or services that
effectively compete with the Company's service offerings, they could be in a
position to substantially lower the price of their 9-1-1 products and services
or to bundle such products and services with their other product and service
offerings.
 
     For the foregoing reasons, there can be no assurance that the Company will
be able to compete successfully against its current and future competitors.
Increased competition may result in price reductions, reduced gross margins and
loss of market share, any of which could materially and adversely affect the
Company's business, financial condition and results of operations. See
"Business -- Competition."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's future success depends in large part on the continued service
of its key management, sales, product development and operational personnel,
including George Heinrichs, President and Chief Executive Officer, John Sims,
Chief Operating Officer, and Nancy Hamilton, Chief Financial Officer, and on the
Company's ability to continue to attract, motivate and retain highly qualified
employees, including technical, managerial and sales and marketing personnel.
Additionally, the Company expects to continue to expand the number of employees
engaged in sales, marketing and product development. However, competition in the
recruitment of highly qualified personnel in the software and telecommunications
services industry is intense and has become particularly significant in the
Denver metropolitan area. The inability to hire and retain qualified personnel
or the loss of the services of key personnel could have a material adverse
effect upon the Company's current business, development efforts and future
business prospects. If such personnel do not remain active in the Company's
business, the Company's operations could be materially adversely affected. The
Company currently maintains a key person life insurance policy only with respect
to Mr. Heinrichs. The Company is the named beneficiary of this $1,000,000
policy. See "Business -- Employees" and "Management."
 
DEPENDENCE ON PROPRIETARY RIGHTS
 
     The Company's success and its ability to compete depends significantly upon
its proprietary rights. The Company relies primarily on a combination of
copyright, trademark and trade secret laws, as well as confidentiality
procedures and contractual restrictions to establish and protect its proprietary
rights. There can be no assurance that such measures will be adequate to protect
the Company's proprietary rights. Further, the Company may be subject to
additional risks as it enters into transactions in foreign countries where
intellectual property laws are not well developed or are difficult to enforce.
Legal protections of the Company's proprietary rights may be ineffective in such
countries. Litigation to defend and enforce the Company's intellectual property
rights could result in substantial costs and diversion of resources, and could
have a material adverse effect on the Company's business, financial condition
and results of operations, regardless of the final outcome of such litigation.
Despite the Company's efforts to safeguard and maintain its proprietary rights,
there can be no assurance that the Company will be successful in doing so or
that the steps taken by the Company in this regard will be adequate to deter
misappropriation or independent third-party development of the Company's
technology, or to prevent an unauthorized third party from copying or otherwise
obtaining and using the
 
                                       13
<PAGE>   16
 
Company's technology. There also can be no assurance that others will not
independently develop similar technologies or duplicate any technology developed
by the Company. Any such events could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     As the number of entrants to the Company's markets increases and the
functionality of the Company's services and products increases and overlaps with
the products and services of other companies, the Company may become subject to
claims of infringement or misappropriation of the intellectual property rights
of others. In certain of its customer agreements, the Company agrees to
indemnify its customers for any expenses or liabilities resulting from claimed
infringements of patents, trademarks or copyrights of third parties. In certain
limited instances, the amount of such indemnities may be greater than the
revenue the Company may have received from the customer. There can be no
assurance that third parties will not assert infringement or misappropriation
claims against the Company in the future with respect to current or future
product or service offerings. Any claims or litigation, with or without merit,
could be time consuming, result in costly litigation or require the Company to
enter into royalty or licensing arrangements. Such royalty or licensing
arrangements, if required, may not be available on terms acceptable to the
Company, if at all, and could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
RISKS ASSOCIATED WITH INTERNATIONAL SALES
 
     Although substantially all of the Company's revenue is generated from sales
to customers in the United States, the Company has generated revenue in Canada
and intends to enter additional international markets, which will require
significant management attention and financial resources. International sales
are subject to a variety of risks, including difficulties in establishing and
managing international distribution channels, and in translating products and
related materials into foreign languages. International operations are also
subject to difficulties in collecting accounts receivable, staffing, managing
personnel and enforcing intellectual property rights. Other factors that can
adversely affect international operations include fluctuations in the value of
foreign currencies and currency exchange rates, changes in import/export duties
and quotas, introduction of tariff or non-tariff barriers and economic or
political changes in international markets. There can be no assurance that these
factors will not have a material adverse effect on the Company's future
international sales and, consequently, on the Company's business, financial
condition and results of operations. Furthermore, any inability to obtain
foreign regulatory approvals on a timely basis could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Overview" and "Business -- Strategy."
 
RISKS RELATING TO POTENTIAL ACQUISITIONS
 
     As part of its overall strategy, the Company regularly evaluates
opportunities to enter into strategic acquisitions, including potential business
combinations and significant investments in complementary companies, assets,
products and technologies, although the Company has no present arrangements,
commitments or agreements with respect to any acquisition. Acquisitions involve
a number of operating risks that could materially adversely affect the Company's
business, financial condition and results of operations, including the diversion
of management's attention to assimilate the operations, products and personnel
of the acquired companies, the amortization of acquired intangible assets, and
the potential loss of key employees of the acquired companies. Furthermore,
acquisitions may involve businesses in which the Company lacks experience.
Because management has limited experience in acquisitions and the Company has no
experience in integrating acquired companies or technologies into its
operations, there can be no assurance that the Company will be able to manage
one or more acquisitions successfully, or that the Company will be able to
integrate the operations, products or personnel gained through any such
acquisitions without a material adverse effect on the Company's business,
financial condition and results of operations. See "Use of Proceeds."
 
YEAR 2000 CAPABILITY
 
     Many currently installed computer and software products are coded to accept
only two digit entries in the date code field. These date code fields will need
to accept four digit entries to distinguish twenty-first century dates from
twentieth century dates. As a result, in less than two years, computer systems
and/or software used
 
                                       14
<PAGE>   17
 
by many companies may need to be upgraded to comply with such "Year 2000"
requirements. Significant uncertainty exists in the software industry concerning
the potential effects associated with such compliance.
 
     The Company believes that the purchasing patterns of customers and
potential customers may be significantly affected by Year 2000 issues. Many
companies are expending significant resources to correct or patch their current
software systems for Year 2000 compliance. These expenditures may result in
reduced funds available to purchase services such as those offered by the
Company. Additionally, Year 2000 issues could cause a significant number of
companies, including current customers of the Company, to re-evaluate their
current system needs, and as a result, consider switching to other systems or
suppliers. This could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     Certain of the Company's current contracts with its customers require that
the Company warrant Year 2000 capability by a certain date. Any failure to
achieve Year 2000 compliance by such date could have a material adverse effect
on the Company's business, financial condition and results of operations.
Although the Company is designing its services and products to be Year 2000
capable and tests third-party software that is incorporated with the Company's
services and products, there can be no assurance that the Company's services and
products, particularly when such products and services incorporate third-party
software, will contain all necessary date code changes in time. The Company
expects to incur approximately $125,000 in costs in 1998 in making its services
and products Year 2000 compliant. Any additional unanticipated expenses could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
     The Company utilizes off-the-shelf and custom software developed internally
and by third parties. To the extent that such software and systems do not comply
with Year 2000 requirements, there can be no assurance that potential systems
interruptions or the cost necessary to update such software will not have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
     Prior to this offering there has been no public market for the Company's
Common Stock, and there can be no assurance that an active public market for the
Company's Common Stock will develop or be sustained after the offering. The
initial offering price will be determined by negotiation among the Company and
the Underwriters based upon several factors. See "Underwriting" for a discussion
of the method of determining the initial public offering price. The trading
price of the Company's Common Stock could be subject to wide fluctuations in
response to variations in operating results, announcements of technological
innovations or new products by the Company or its competitors, changes in
financial estimates by securities analysts, and other events or factors. In
addition, the stock market has experienced volatility that has particularly
affected the market prices of equity securities of many high technology
companies and that often has been unrelated to the operating performance of such
companies. These broad market fluctuations may materially adversely affect the
market price of the Company's Common Stock.
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
   
     The purchasers of Common Stock in this offering will experience immediate
and substantial dilution in the net tangible book value per share of their
Common Stock. At an assumed initial public offering price of $14.00 per share
and after deducting estimated offering expenses payable by the Company and
estimated underwriting discounts and commissions, investors in this offering
will incur dilution of $11.04 per share. See "Dilution."
    
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
     Sales of a substantial number of shares of Common Stock in the public
market following this offering could adversely affect the market price for the
Company's Common Stock. The number of shares of Common Stock available for sale
in the public market is limited by restrictions under the Securities Act of
1933, as amended (the "Securities Act"), and lock-up agreements under which the
holders of such shares have agreed not to sell or otherwise dispose of any of
their shares for a period of 180 days after the date of this Prospectus without
the prior written consent of the BancAmerica Robertson Stephens. However,
BancAmerica Robertson Stephens, in its sole discretion and at any time without
notice, may release all or any portion of the securities subject to lock-up
agreements. When determining whether or not to release shares from the lock-up
 
                                       15
<PAGE>   18
 
agreements, BancAmerica Robertson Stephens may consider, among other factors,
the holder's reasons for requesting the release, the number of shares for which
the release is being requested and market conditions at the time. As a result of
these restrictions, based on shares outstanding and options granted as of April
9, 1998, assuming no options are exercised between April 9, 1998 and the date of
this Prospectus, the following shares of Common Stock will be eligible for
future sale: on the date of this Prospectus, 3,361,469 shares (including the
3,300,000 shares offered hereby) will be eligible for sale; an additional
6,774,435 shares will be eligible for sale 180 days after the date of this
Prospectus. In addition, the Company intends to register on a registration
statement on Form S-8, approximately 90 days following the effective date of
this offering, a total of 1,901,055 shares of Common Stock subject to
outstanding options or reserved for issuance under the 1998 Stock Incentive
Plan. Upon expiration of the lock-up agreements referred to above, holders of
approximately 6,383,723 shares of Common Stock will be entitled to certain
registration rights with respect to such shares. 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 could have a material adverse effect on
the market price for the Company's Common Stock. See "Shares Eligible for Future
Sale."
 
CONTROL BY EXISTING STOCKHOLDERS; EFFECTS OF CERTAIN ANTI-TAKEOVER PROVISIONS
 
     Following the completion of this offering, members of the Board of
Directors and the executive officers of the Company, together with members of
their families and entities that may be deemed affiliates of or related to such
persons or entities, will beneficially own approximately 52.7% of the
outstanding shares of Common Stock of the Company. Accordingly, these
stockholders will be able to elect all members of the Company's Board of
Directors and determine the outcome of corporate actions requiring stockholder
approval, such as mergers and acquisitions. This level of ownership by such
persons and entities may have a significant effect in delaying, deferring or
preventing a change in control of the Company and may adversely affect the
voting and other rights of other holders of Common Stock. Certain provisions of
the Company's Amended and Restated Certificate of Incorporation, Amended and
Restated Bylaws, Delaware law and equity incentive plans also may discourage
certain transactions involving a change in control of the Company. This level of
ownership by such persons and entities, when combined with the ability of the
Board of Directors to issue "blank check" preferred stock without further
stockholder approval, may have the effect of delaying, deferring or preventing a
change in control of the Company. See "Management -- Directors and Executive
Officers," "Certain Transactions," "Principal and Selling Stockholders" and
"Description of Capital Stock."
 
MANAGEMENT'S DISCRETION OVER PROCEEDS OF THE OFFERING
 
     The primary purposes of this offering are to create a public market for the
Common Stock, to facilitate future access by the Company to public equity
markets and to obtain additional equity capital. As of the date of this
Prospectus, the Company has no specific plans as to the use of the net proceeds
from this offering, other than to pay $4,610,000 of outstanding bank
indebtedness and a related prepayment premium; accordingly, the Company's
management will have broad discretion as to the application of such net
proceeds. Pending any such uses, the Company plans to invest the net proceeds in
short-term, investment grade, interest-bearing securities. See "Use of
Proceeds."
 
NO DIVIDENDS
 
     The Company has not paid any cash or other dividends on its Common Stock,
nor does it expect to pay dividends in the foreseeable future. See "Dividend
Policy."
 
BENEFITS OF THE OFFERING TO CURRENT STOCKHOLDERS
 
     The completion of the offering made by this Prospectus will provide
significant benefits to the current stockholders of the Company, including
certain of its Directors and officers. The net proceeds to the Selling
Stockholders from the sale of the 1,200,000 shares of Common Stock offered by
them hereby, assuming an initial public offering price of $14.00 and after
deducting estimated underwriting discounts and commissions, are estimated to be
approximately $15.6 million. The Company will not receive any of the proceeds
from the sale of shares by the Selling Stockholders. The completion of this
offering will also create a public market for the Common Stock and thereby is
expected to increase the market value of the investment by current stockholders
in the Company. Upon the closing of this offering at the assumed initial public
offering price of
 
                                       16
<PAGE>   19
 
$14.00, the difference between the aggregate purchase price paid or payable by
the Company's named executive officers for shares of Common Stock held by them
or subject to options held by them and the aggregate market value of such shares
will be approximately $11.1 million. See "Dilution."
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 2,100,000 shares of
Common Stock offered by the Company hereby, assuming an initial public offering
price of $14.00 and after deducting estimated expenses payable in connection
with this offering and estimated underwriting discounts and commissions, are
estimated to be approximately $26,542,000 ($30,643,000 if the Underwriters'
over-allotment option is exercised in full). The Company will not receive any
proceeds from the sale of Common Stock by the Selling Stockholders. The
principal purposes of this offering are to create a public market for the
Company's Common Stock, to facilitate future access by the Company to public
equity markets and to increase the Company's equity capital.
 
     The Company intends to use $4.6 million of the proceeds to pay outstanding
bank indebtedness and a related prepayment premium. Of this amount, $4.0 million
will be used to prepay outstanding indebtedness and to pay a prepayment premium
of $160,000, pursuant to the Company's loan agreement with a bank. Such
indebtedness currently bears interest at the rate of 11% per annum and requires
principal payments of $250,000 beginning on March 31, 2001 and each subsequent
quarter end through December 31, 2002. Thereafter, principal payments of
$500,000 are due on March 31, 2003 and each subsequent quarter end, with the
final payment becoming due on November 30, 2003. Additionally, the Company
intends to use a portion of the proceeds to repay $450,000 outstanding under its
line of credit. Borrowings under the line of credit bear interest at prime rate
plus 1% (9.5% at April 30, 1998) and are due on April 15, 1999. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
     The Company expects to use its remaining net proceeds (estimated to be
approximately $21.9 million) for product development and general corporate
purposes, including working capital. A portion of the net proceeds also may be
used for the acquisition of businesses, products and technologies that are
complementary to those of the Company. While the Company regularly evaluates
opportunities to enter into strategic acquisitions, including potential business
combinations and investments in complementary companies, assets, products and
technologies, the Company has no present arrangements, commitments or agreements
with respect to any acquisition. Pending such uses, the Company intends to
invest the net proceeds from this offering in short-term, investment-grade,
interest-bearing securities.
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid dividends on its capital stock and
does not anticipate paying cash dividends within the foreseeable future. Certain
covenants contained in the Company's line of credit agreement and a loan
agreement restrict the payment of any dividends without the lender's prior
consent. Payments of future dividends, if any, will be at the discretion of the
Company's Board of Directors, subject to the restrictions discussed above, after
taking into account various factors, including the Company's financial
condition, operating results, cash needs and expansion plans. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

                                 CAPITALIZATION
 
     The following table sets forth the capitalization of the Company as of
March 31, 1998: (i) on an actual basis; (ii) on a pro forma basis giving effect
to the conversion of all outstanding shares of Convertible Preferred Stock and
the exercise of an outstanding warrant to purchase shares of Common Stock, all
upon the closing of this offering; and (iii) on a pro forma basis, as further
adjusted to reflect the receipt of the estimated net proceeds from the sale of
2,100,000 shares of Common Stock offered by the Company hereby at an assumed
initial public offering price of $14.00 and the application of the net proceeds
therefrom as described under "Use of Proceeds." This table should be read in
conjunction with the Financial Statements and Notes thereto appearing elsewhere
in this Prospectus.

(1) Excludes 1,116,126 shares of Common Stock issuable upon exercise of stock
    options outstanding as of March 31, 1998 at a weighted average exercise
    price of $3.13 per share, and 117,442 shares of Common Stock reserved for
    grant of future options as of March 31, 1998, under the 1990 Stock Option
    Plan. From April 1, 1998 to April 30, 1998, the Company issued 846 shares of
    Common Stock upon the exercise of outstanding options and granted options to
    purchase 3,333 shares of Common Stock pursuant to the 1990 Stock Option
    Plan. In addition, the number of shares reserved for issuance under the 1990
    Stock Option Plan was increased by 166,667 shares effective April 7, 1998.
    On the effective date of the Registration Statement of which this Prospectus
    is a part, an additional 500,000 share reserve will be created under the
    Company's 1998 Stock Incentive Plan. See "Management -- Benefit

                                    DILUTION
 
   
     The pro forma net tangible book value of the Company at March 31, 1998 was
approximately $4,354,000, or $0.52 per share. Pro forma net tangible book value
per share represents the total amount of the Company's tangible assets less
total liabilities, divided by the number of shares of Common Stock outstanding
after giving effect to the conversion of all outstanding Convertible Preferred
Stock and the exercise of an outstanding warrant. After giving effect to the
sale of 2,100,000 shares of Common Stock offered hereby by the Company at an
assumed initial public offering price of $14.00 per share and after deducting
estimated offering expenses payable by the Company and estimated underwriting
discounts and commissions, the Company's pro forma net tangible book value at
March 31, 1998, would have been $30,896,000, or $2.96 per share. This represents
an immediate dilution of $11.04 per share to new investors purchasing shares of
Common Stock in this offering. The following table illustrates this dilution:

(1) Sales by the Selling Stockholders in this offering will reduce the number of
    shares held by the existing stockholders to 7,142,007 or approximately 68.4%
    of the total number of shares of Common Stock outstanding after this
    offering, and will increase the number of shares to be purchased by new
    investors to 3,300,000 or approximately 31.6% of the total number of shares
    of Common Stock outstanding after the offering. See "Principal and Selling
    Stockholders."
 
     The foregoing tables assume no exercise of outstanding options. As of March
31, 1998, there were outstanding stock options to purchase an aggregate of
1,116,126 additional shares of Common Stock at a weighted average exercise price
of $3.13 per share. To the extent that these options are exercised, there will
be further dilution to new investors. See "Management -- Benefit Plans -- 1998

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     This Prospectus contains forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including those set forth under "Risk Factors" and elsewhere in this Prospectus.
The following discussion should be read in conjunction with the Financial
Statements and Notes thereto included elsewhere in this Prospectus.
 
OVERVIEW
 
     SCC is the leading provider of 9-1-1 OSS services to ILECs, CLECs and
wireless carriers in the United States. The Company manages the data that enable
a 9-1-1 call to be routed to the appropriate public safety agency with accurate
and timely information about the caller's identification and location. The
Company was incorporated in July 1979 in the State of Colorado under the name
Systems Concepts of Colorado, Inc. and was reincorporated in September 1993 in
the State of Delaware under the name SCC Communications Corp. Prior to 1995,
substantially all of the Company's revenue was derived from the sale of software
licenses and related implementation services to ILECs and public safety
agencies. During 1994, the Company began investing in infrastructure to provide
its 9-1-1 OSS solution to telephone operating companies seeking to outsource
such operations. The Company signed its first 9-1-1 data management services
contract in August 1994 and added to the number of records under management
during 1995, 1996 and 1997. The Company began to recognize revenue from wireless
carriers in the third quarter of 1997, and a growing percentage of the Company's
revenue has been derived from the management of 9-1-1 data records for wireless
carriers.
 
     SCC's data management services revenue is derived from contracts with
ILECs, CLECs and wireless carriers pursuant to which the Company provides an
outsourcing solution for its customers' 9-1-1 data management. Revenue included
in data management services generally includes a non-recurring initial fee for
the design and implementation of the 9-1-1 OSS, conversion of the customer's
data to the Company's systems, hiring and training of personnel, and other costs
required to prepare for the processing of customer data. Non-recurring fees are
recognized on the percentage-of-completion method over the period required to
perform the tasks necessary to prepare for the processing of customer data. The
Company also generally receives a monthly service fee based on the number of
subscriber records under management, which is recognized in the period in which
the services are rendered. Data management services revenue also may include
revenue from enhanced products and services, which are recognized in the period
to which the services are performed. Related costs are expensed as they are
incurred. Data management services revenue comprised 48%, 89% and 89% of the
Company's total revenue in the years ended December 31, 1995, 1996 and 1997,
respectively, and 95% in the three months ended March 31, 1998.
 
     SCC's licenses and implementation services revenue is derived from
contracts with ILECs pursuant to which the Company provides a 9-1-1 software
license or related products and services such as implementation, training,
software enhancements and interfaces to its customers' systems. Licenses and
implementation services revenue is recognized using the percentage-of-completion
method. The related costs include third-party licenses, direct labor and related
expenses, and are expensed as incurred. Subsequent to system installation, the
Company provides its customers with maintenance services that are recognized
ratably over the related contract period on a straight-line basis. The Company's
licenses and implementation services revenue is derived from a limited number of
customers and consequently the concentration of customers can result in
quarterly fluctuations based on the timing of the signing of new contracts and
completion of existing contracts. Margins on such contracts also may fluctuate
based on the elements included in the contract. Licenses and implementation
services revenue comprised 52%, 11% and 11% of the Company's total revenue in
the years ended December 31, 1995, 1996 and 1997, respectively, and 5% in the
three months ended March 31, 1998.
 
     During the year ended December 31, 1996, the Company recognized
approximately 82% of total revenue from continuing operations from Ameritech and
U.S. WEST, each of which accounted for greater than 10% of
 
                                       21
<PAGE>   24
 
the Company's total revenue in such periods. During the year ended December 31,
1997, the Company recognized approximately 81% of total revenue from Ameritech,
BellSouth Inc. and U.S. WEST, each of which accounted for greater than 10% of
the Company's total revenue in such periods. During the three months ended March
31, 1998, the Company recognized approximately 92% of total revenue from four
customers, each of which accounted for greater than 10% of the Company's total
revenue in such periods. See "Risk Factors -- Reliance on Significant
Customers."
 
   
     As of December 31, 1997, the Company had net operating loss carryforwards
of $9.6 million available to offset future net income for U.S. federal income
tax purposes. Thus, the Company's income tax provision for past fiscal years
consisted of alternative minimum taxes, state income taxes in states where the
Company has not had net operating loss carryforwards to offset net income, and
foreign taxes. As of December 31, 1997, the Company reversed $2.5 million of the
valuation allowance on its deferred tax assets as the Company believes that it
is more likely than not that such tax benefits will be realized. There is no
assurance that the Company's remaining deferred tax benefit will be offset by
future taxable income or will not be restricted in the future due to
transactions entered into by the Company or changes in tax legislation.
    
 
     In June 1997, the Company sold the net assets of its Premise Products
Division. The sale of the Company's Premise Products Division resulted in a net
loss from the sale of $2.0 million. Net losses from operations of this division
totaled $1.7 million, $562,000 and $876,000 in 1995, 1996 and 1997,
respectively, and are presented in the Company's financial statements as loss
from operations of discontinued division.
 
     Historically, substantially all of the Company's revenue has been generated
from sales to customers in the United States. However, the Company has generated
revenue in Canada and intends to enter additional international markets, which
may require significant management attention and financial resources.
International sales are subject to a variety of risks. See "Risk
Factors -- Risks Associated with International Sales."
 
     The Company's quarterly and annual operating results have varied
significantly in the past. The variation in operating results will likely
continue and may intensify. Although the Company was profitable in seven of its
last eight quarters, there can be no assurance that the Company's profitability
will continue in the future or, if the Company is profitable, that its levels of
profitability will not vary significantly between quarters. Accordingly, the
Company believes that period to period comparisons of results of operations are
not necessarily meaningful and should not be relied upon as indications of
future performance. The Company's operating results may fluctuate as a result of
many factors, including the length of the sales cycles for new or existing
customers, the size, timing or duration of significant customer contracts,
fluctuations in number of subscriber records under management, timing or
duration of service offerings, ability of the Company to hire, train and retain
qualified personnel, increased competition, changes in operating expenses,
changes in Company strategy, the financial performance of the Company's
customers, changes in telecommunications legislation and regulations that may
affect the competitive environment for the Company's services, and general
economic factors. The Company's contracts for 9-1-1 OSS services generally
include a non-recurring initial fee, and therefore, the Company may recognize
significantly increased revenue for a short period of time upon commencing
services for a new customer.
 
     The Company's expense levels are based in significant part on its
expectations regarding future revenue. The Company's revenue is difficult to
forecast because the market for the Company's 9-1-1 OSS services is rapidly
evolving. In addition, the Company's sales cycle and the size and timing of
significant customer contracts, license fees and non-recurring initial fees vary
substantially among customers depending on the level of service provided.
Accordingly, the Company may be unable to adjust spending in a timely manner to
compensate for any unexpected shortfall in revenue. Any significant shortfall
could therefore have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, the Company hired
additional employees in 1996, 1997 and the three months ended March 31, 1998,
and expects to continue hiring additional employees during 1998. The Company
expects that this increase will affect the Company's operating margins for the
short term. There can be no assurance that the Company can continue to report
operating profits, and failure to do so is likely to have a material adverse
effect on the Company's financial results. See "Risk Factors -- Significant
Fluctuations in Quarterly Results of Operations" and "-- Management of Change."

THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO THREE MONTHS ENDED MARCH 31, 1997
 
  Revenue
 
     Total Revenue. Total revenue increased 54%, from $5.1 million in the first
quarter of 1997 to $7.9 million in the first quarter of 1998.
 
     Data Management Services Revenue. Revenues from data management services
increased 55%, from $4.9 million in the first quarter of 1997 to $7.5 million in
the first quarter of 1998, representing approximately 95% of total revenue in
both periods. The increase resulted primarily from (i) non-recurring and monthly
fees from wireless customers in the first quarter of 1998, as the Company did
not begin to earn revenue from wireless customers until the third quarter of
1997, (ii) increased monthly fees from wireline customers, as the Company had
not completed the transition of records for a major customer in the first
quarter of 1997, and (iii) non-recurring fees from enhanced services provided in
the first quarter of 1998.
 
     Licenses and Implementation Services. Revenue from licenses and
implementation services increased 36%, from $271,000 in the first quarter of
1997 to $369,000 in the first quarter of 1998, as the Company earned revenue in
1998 related to a contract that was not in place in the first quarter of 1997.
 
                                       23
<PAGE>   26
 
  Costs and Expenses
 
     Cost of Data Management Services. Cost of data management services consists
primarily of labor and costs of interconnection with customers' systems and the
Company's infrastructure. Cost of data management services increased 54%, from
$3.1 million in the first quarter of 1997 to $4.8 million in the first quarter
of 1998, representing 61% and 64% of total revenue and data management services
revenue, respectively, in both periods. The dollar increase was due to the
addition of personnel and expansion of facilities to accommodate growth in the
Company's wireless and wireline operations.
 
     Cost of Licenses and Implementation Services. Cost of licenses and
implementation services consists primarily of labor, license fees for third
party software and related expenses. Cost of licenses and implementation
services increased 56%, from $98,000 in the first quarter of 1997 to $153,000 in
the first quarter of 1998, representing 2% of total revenue in both periods and
36% and 42% of licenses and implementation services revenue in the first quarter
of 1997 and the first quarter of 1998, respectively. The increase in dollars and
as a percent of licenses and implementation services revenue was due to work
performed on a contract in the first quarter of 1998 which contained higher cost
elements, including third-party software, than contracts in process in the first
quarter of 1997.
 
     Sales and Marketing. Sales and marketing expenses consist primarily of
expenses related to salaries and commissions, travel, trade shows and sales
collateral. Sales and marketing expenses decreased 10%, from $933,000 in the
first quarter of 1997 to $843,000 in the first quarter of 1998, representing 18%
and 11% of total revenue in the first quarter of 1997 and the first quarter of
1998, respectively. The decrease was primarily due to decreased commissions and
bonuses in the first quarter of 1998 caused by a change in the structure of the
incentive plans and a bonus paid to an individual in the first quarter of 1997,
as well as the transfer of a vice president to a general and administrative
position. These decreases were offset by increased headcount and public
relations costs.
 
     General and Administrative. General and administrative expenses consist
primarily of expenses related to the Company's information systems, finance,
human resources, legal, executive and financial planning departments. General
and administrative expenses increased 136%, from $485,000 in the first quarter
of 1997 to $1.1 million in the first quarter of 1998, representing 10% and 15%
of total revenue in the first quarter of 1997 and the first quarter of 1998,
respectively. The dollar increase was due to (i) the reassignment of certain
continuing resources, infrastructure and related general and administrative
expenses applicable to continuing operations, (ii) addition of personnel and
computer equipment in the accounting, information systems and human resources
departments to support the Company's growth and (iii) increased executive
bonuses due to increased profitability in the first quarter of 1998.
 
     Other Expenses, Net. Net other expenses consist primarily of interest
expense from the Company's borrowings and leases for capital equipment, offset
by interest income earned on the Company's cash balances. Other expenses
increased 101%, from $150,000 in the first quarter of 1997 to $301,000 in the
first quarter of 1998, representing 3% and 4% of total revenue in the first
quarter of 1997 and the first quarter of 1998, respectively. The dollar increase
was primarily due to interest related to the 4.0 million loan from a bank that
was outstanding in the first quarter of 1998, which was partially offset by
decreased interest expense resulting from a lower balance outstanding on the
Company's line of credit in the first quarter of 1998.
 
     Provision for income taxes. The Company's income tax provision increased
from $24,000 in the first quarter of 1997 to $46,000 in the first quarter of
1998 due to increased income generated in states where the Company did not have
net operating loss carryforwards available to offset net income.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
  Revenue
 
     Total Revenue. Total revenue increased 83%, from $14.8 million in 1996 to
$27.1 million in 1997.
 
     Data Management Services Revenue. Revenue from data management services
increased 82%, from $13.2 million in 1996 to $24.0 million in 1997, representing
approximately 89% of total revenue in both years. This increase resulted from an
increase in non-recurring and monthly fees from existing customers, increased
 
                                       24
<PAGE>   27
 
sales of new services to existing customers, and the realization of
non-recurring and monthly fees from both wireline and wireless customers.
 
     Licenses and Implementation Services Revenue. Revenue from licenses and
implementation services increased 87%, from $1.6 million in 1996 to $3.1 million
in 1997. The increase resulted from the addition of a new contract in 1997.
 
  Costs and Expenses
 
     Cost of Data Management Services. Cost of data management services
increased 92%, from $8.0 million in 1996 to $15.4 million in 1997, representing
54% and 57%, respectively, of total revenue and 61% and 64%, respectively, of
data management services revenue. The increase as a percentage of total revenue
and data management services revenue resulted from the addition of employees and
other resources in early 1997 in anticipation of wireless contracts, although
the Company did not begin recognizing revenue from such contracts until the
third quarter of 1997.
 
     Cost of Licenses and Implementation Services. Cost of licenses and
implementation services increased 115%, from $596,000 in 1996 to $1.3 million in
1997, representing 4% and 5%, respectively, of total revenue and 36% and 42%,
respectively, of licenses and implementation services revenue. The increase as a
percentage of associated revenue was due to the inclusion of higher cost
elements, including third-party software, in contracts performed in 1997.
 
     Sales and Marketing. Sales and marketing expenses increased 20%, from $3.2
million in 1996 to $3.9 million in 1997, representing 22% and 14%, respectively,
of total revenue. The increase in dollar amount was primarily due to increases
in salaries, recruiting, relocation and travel costs caused by an increase in
the sales force and increased marketing activities in 1997. The remaining
increase was due to the reassignment of marketing resources and related expenses
to the Company's continuing operations.
 
     General and Administrative. General and administrative expenses increased
111%, from $1.5 million in 1996 to $3.2 million in 1997, representing 10% and
12%, respectively, of total revenue. Approximately $1.0 million of the increase
is related to the reassignment of certain continuing resources, infrastructure
and related general and administrative expenses applicable to the Company's
continuing operations. The remaining dollar and percentage increases resulted
primarily from increased costs necessary to develop and maintain the internal
and customer support information systems, increased depreciation expense in
1997, increased executive bonuses paid and accrued in 1997, and expansion of the
Company's facilities to accommodate the Company's growth.
 
     Other Expenses, Net. Other expenses increased 67%, from $527,000 in 1996 to
$879,000 in 1997, representing 4% and 3% of total revenue in 1996 and 1997,
respectively. The increase in dollar amount resulted from an increase in
interest expense caused by an increase in capital leases, a higher average
balance outstanding on the Company's line of credit in 1997, and interest
expense related to a $4.0 million borrowing in November 1997. This increase was
partially offset by an increase in interest income recognized, as the Company's
average cash balance increased in 1997.
 
   
     Provision (Benefit) for Income Taxes. The Company's income tax provision
(benefit) changed from a provision of $9,000 in 1996 to a benefit of
$(2,328,000) in 1997. In 1997, the Company recorded an income tax benefit of
$2.5 million due to the reversal of a portion of the Company's valuation
allowance on its deferred tax assets. Excluding this benefit, the Company had an
income tax provision of $172,000. This increase over 1996 was due to a foreign
income tax refund received in 1996. In addition, the Company's state income tax
provision increased in 1997, as the Company generated more income in states in
which the Company did not have net operating loss carryforwards available to
offset net income.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
  Revenue
 
     Total Revenue. Total revenue increased 100%, from $7.4 million in 1995 to
$14.8 million in 1996.
 
     Data Management Services Revenue. Revenue from data management services
increased 273%, from $3.5 million in 1995 to $13.2 million in 1996, representing
48% and 89%, respectively, of total revenue. The increase in dollar amount
resulted from increased revenue from non-recurring and monthly fees in 1996 from
both existing and new wireline customers.
 
     Licenses and Implementation Services Revenue. Revenue from licenses and
implementation services decreased 58%, from $3.9 million in 1995 to $1.6 million
in 1996, representing 52% and 11%, respectively, of total revenue. The decrease
resulted from the implementation of a large project in 1995 without a comparable
amount of new business in 1996.
 
  Costs and Expenses
 
     Cost of Data Management Services. Cost of data management services
increased 182%, from $2.8 million in 1995 to $8.0 million in 1996, representing
38% and 54%, respectively, of total revenue and 80% and 61%, respectively, of
data management services revenue. Cost of data management services was greater
as a percentage of the related revenue in 1995 because the Company was building
the infrastructure for its data management services business, including hiring
and training employees, building the network infrastructure, preparing
facilities and converting data to the Company's systems. Cost of data management
services was higher as a percentage of total revenue in 1996 due to the
increased percentage of data management services revenue.
 
     Cost of Licenses and Implementation Services. Cost of licenses and
implementation services decreased 43%, from $1.0 million in 1995 to $596,000 in
1996, representing 14% and 4%, respectively, of total revenue and 27% and 36%,
respectively, of licenses and implementation services revenue. The increase as a
percentage of associated revenue was due to the inclusion of higher cost
elements, including third-party software, on contracts in 1996.
 
     Sales and Marketing. Sales and marketing expenses increased 59%, from $2.0
million in 1995 to $3.2 million in 1996, representing 27% and 22%, respectively,
of total revenue. The increase in dollar amount was primarily due to increased
salary, travel and related facilities costs caused by an increase in the sales
force, increased sales commissions and bonuses due to increased revenue, and
increased costs for trade shows. The remaining increase was due to an increase
in certain marketing expenses from the growth of continuing operations of the
Company.
 
     General and Administrative. General and administrative expenses increased
85%, from $830,000 in 1995 to $1.5 million in 1996, representing 11% and 10%,
respectively, of total revenue. This increase in dollar amount was primarily due
to salaries, travel and other costs related to the hiring of management and
other personnel in anticipation of growth in 1996. The increase was partially
offset by decreased relocation, bad debt and consulting expenses.
 
     Other Expenses, Net. Net other expenses increased 43%, from $368,000 in
1995 to $527,000 in 1996, representing 5% and 4%, respectively, of total
revenue. The increase in dollar amount was due to an increase in interest
expense primarily related to additional capital leases for equipment required to
operate the Company's data management services business. This increase was
partially offset by a decrease in interest expense caused by the conversion to
equity and repayment of certain notes payable in 1996.
 
     Provision for Income Taxes. The income tax provision decreased 44%, from
$16,000 in 1995 to $9,000 in 1996. This decrease was primarily due to a foreign
income tax refund received in 1996, offset by additional income generated in
1996 in states in which the Company did not have net operating loss
carryforwards available to offset net income.

LIQUIDITY AND CAPITAL RESOURCES
 
     Since its inception the Company has funded its operations through cash
provided by operations, supplemented by equity and debt financing and leases on
capital equipment. As of March 31, 1998, the Company had $1.2 million in cash
and cash equivalents and $2.9 million in net accounts receivable. In 1996, the
Company generated cash from financing activities through the issuance of shares
of Convertible Preferred Stock for $4.0 million. In addition, the Company
borrowed $4.0 million in 1997 from a bank. The loan bears interest at 11%
through May 31, 1999, and at 12% thereafter through maturity. Principal payments
of $250,000 are due beginning on March 31, 2001, and will be payable at each
subsequent quarter end through December 31, 2002. Principal payments of $500,000
are due on March 31, 2003 and at each subsequent quarter end, with the final
payment due November 30, 2003. The Company may prepay the loan after June 30,
1998; however, a prepayment premium will be due equal to 4% of the amount
outstanding if prepaid between June 30, 1998 and November 30, 1998, 3% if
prepaid between December 1, 1998 and November 30, 1999 and 2% if prepaid between
December 1, 1999 and November 30, 2000. The loan is secured by a first priority
security interest in substantially all of the Company's assets. As of the date
of this Prospectus, the Company was in compliance with all covenants related to
this debt. The Company intends to use a portion of the proceeds from this
offering to prepay the $4.0 million of borrowings and to pay a prepayment
premium of $160,000.
 
   
     The Company used cash in 1996 and 1997 of $2.4 million and $2.6 million,
respectively, for the purchase of capital assets, primarily for use in the
delivery of its data management services. The Company anticipates making a
comparable level of capital expenditures during 1998, although it currently has
no material commitments for capital expenditures. The Company also paid $2.5
million and $3.6 million in 1996 and 1997, respectively, toward its lease
obligations for capital equipment. The Company hired a significant number of new
employees in 1996, 1997 and the first three months of 1998, and expects to
continue hiring a significant number of additional employees during the
remainder of 1998.
    
 
     The Company has a line of credit with a bank equal to the lesser of 75% of
qualifying accounts receivable or $2.0 million available to meet operating
needs. Amounts borrowed under the line of credit bear interest at prime rate
plus 1% (9.5% at April 30, 1998) and are due April 15, 1999. The Company intends
to renew this line of credit. The credit line is collateralized by certain
assets of the Company. As of March 31, 1998, $450,000 was outstanding on the
line of credit. During 1996 and 1997, the Company had net borrowings under its
bank notes and line of credit of $623,000 and $2.8 million, respectively. The
Company intends to use a portion of the proceeds from this offering to repay the
$450,000 outstanding under its line of credit.
 
     The Company is designing its services and products to be Year 2000 capable
and tests third-party software that is incorporated with the Company's services
and products. There can be no assurance, however, that the Company's services
and products, particularly when such services and products incorporate third-
party software, will contain all necessary date code changes in time. The
Company expects to incur approximately $125,000 in costs in 1998 in making its
services and products Year 2000 compliant. Any additional unanticipated expenses
could have an adverse effect on the Company's business, financial condition and
results of operations. See "Risk Factors -- Year 2000 Capability."
 
   
     The Company believes that the remaining net proceeds from this offering,
together with cash generated from operations, will be sufficient to fund its
anticipated working needs, capital expenditures and any potential future
acquisitions for at least 1999. In the event the Company's plans or assumptions
change or prove to be inaccurate, or if the Company consummates any unplanned
acquisitions of businesses or assets, the Company may be required to seek
additional sources of capital. Sources of additional capital may include public
and private equity and debt financings, sales of nonstrategic assets and other
financing arrangements.
    
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 130 ("SFAS 130"), "Reporting
Comprehensive Income." This statement, effective for fiscal years beginning
after December 15, 1997, would require the Company to report components of
comprehensive income in a financial statement that is displayed with the same
prominence as other
                                       28
<PAGE>   31
 
financial statements. Comprehensive income is defined by Concepts Statement No.
6, "Elements of Financial Statements," as the change in equity of a business
enterprise during a period from transactions and other events and circumstances
from nonowner sources. It includes all changes in equity during a period except
those resulting from investments by owners and distributions to owners. The
Company adopted SFAS 130 in the first quarter of 1998, however, the Company did
not have any transactions which would require additional disclosure under SFAS
130.
 
     Also in June 1997, the FASB issued Statement of Financial Accounting
Standards No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise and
Related Information." This statement, effective for financial statements for
periods beginning after December 15, 1997, requires that a public business
enterprise report financial and descriptive information about its reportable
operating segments. Generally, financial information is required to be reported
on the basis that it is used internally for evaluation of segment performance
and deciding how to allocate resources to segments. The adoption of SFAS 131 is
not expected to have a material impact on the Company's financial statements.

THE COMPANY
 
     SCC Communications Corp. ("SCC" or the "Company") is the leading provider
of 9-1-1 operations support systems ("OSS") services to incumbent local exchange
carriers ("ILECs"), competitive local exchange carriers ("CLECs") and wireless
carriers in the United States. The Company has redefined the U.S. market for
9-1-1 OSS by creating the first and largest 9-1-1 service bureau, the SCC
National Data Services Center ("NDSC"), with over 70 million subscriber data
records under management throughout North America. The Company manages the data
that enable a 9-1-1 call to be routed to the appropriate public safety agency
with accurate and timely information about the caller's identification and
location. Through SCC's NDSC, the Company offers a comprehensive, cost-effective
solution to the 9-1-1 service provisioning needs of ILECs, CLECs and wireless
carriers by enabling them to outsource virtually all aspects of the operations
of their 9-1-1 data management services, including system activation, routine
data administration, event transaction processing and performance management,
with a high level of security and survivability. In addition, the Company
licenses its 9-1-1 OSS software to carriers that wish to manage the delivery of
9-1-1 data management services in-house. Representative carriers using SCC's
solution include Ameritech, AT&T Wireless Services, BellSouth, MCI, Sprint PCS
and Worldcom Network SVCS.
 
     ILECs, CLECs and wireless carriers require a 9-1-1 solution that cost
effectively provides a high degree of data integrity and reliability, allows
them to comply with regulatory mandates, and addresses their need to provide
additional value-added services. Through SCC's NDSC, the Company provides the
data management services that ILECs, CLECs and wireless carriers need to deliver
9-1-1 calls to the appropriate PSAP, along with critical information such as the
caller's location and call-back number that PSAPs need to respond effectively to
emergencies. Complex data screening and preparation are completed to initialize
properly the underlying systems necessary for 9-1-1 call routing and information
display for the call taker. SCC's NDSC frequently receives and processes
electronic transmissions from ILECs, CLECs and wireless carriers detailing
subscriber and coverage updates and public safety jurisdiction boundary changes
from PSAPs. Records identified as potentially having problems are automatically
separated for manual review and analysis by SCC data integrity analysts. Using
the updated information, SCC's 9-1-1 OSS then provides the information to route
the 9-1-1 call and transmit essential information to the emergency service
provider.
 
INDUSTRY BACKGROUND
 
     Historically, telecommunications carriers in the United States operated in
a highly regulated environment, with both local and long distance service
providers operating as monopolies. The U.S. telecommunications market opened to
competition with the 1984 breakup of AT&T into seven independent Regional Bell
Operating Companies ("RBOCs"). In the early 1990's, the RBOCs and other ILECs,
anticipating regulatory changes that would introduce competition in their local
exchange markets, began restructuring their service models to provide increased
operating efficiencies and new revenue opportunities. Competitive pressures on
the ILECs intensified with the passage of the Telecommunications Act of 1996
(the "1996 Act"), which allowed CLECs, long distance carriers and wireless
carriers to enter local exchange markets. In addition, the regulatory mandates
of the 1996 Act required each carrier to modify its technical infrastructure to
allow for fair and equal access by other carriers. ILECs, CLECs and wireless
carriers began to seek competitive advantages by differentiating their service
offerings, improving service quality, decreasing time to market, introducing new
services and increasing cost efficiencies. To gain these advantages, carriers
streamlined their business practices, in part by updating technological
infrastructure.
 
     Previously, carriers operated effectively using closed and proprietary
systems to provision and manage their networks. In order to deliver services
demanded by an increasingly competitive market, service providers today require
more advanced service provisioning, operations, customer care and billing, and
planning and engineering systems. These systems that collectively constitute a
carrier's OSS directly support the routine processes and procedures of a
carrier's telecommunications operating infrastructure. Historically, carriers'
OSS have typically been "legacy" mainframe-based systems that in many cases
utilized incompatible and inflexible software and technologies. These OSS were
further strained by the many incremental changes that
 
                                       30
<PAGE>   33
 
had been made in order to accommodate new technologies, such as new advanced
switching capabilities, and the proliferation of value-added services, such as
greater consumer choice in mix of services. Recent improvements in OSS, however,
have allowed carriers to offer more advanced services by incorporating new
technologies to improve the reliability of existing infrastructure and to comply
with the regulatory requirements of the 1996 Act. For example, next-generation
customer care and billing systems, which interact with multiple carriers'
systems across the increasingly complex telecommunications network environment,
collect and process customer usage data and generate invoices, enhance the
billing collection process, and provide information regarding customer behavior.
9-1-1, another essential OSS service, similarly requires close coordination of
data and network elements, because changes in customer service information
usually affect the data needed for 9-1-1 services.
 
     9-1-1 service involves the routing of emergency calls to the appropriate
public safety answering point ("PSAP") responsible for dispatching police, fire
and other emergency services. Most jurisdictions in the United States now
provide enhanced 9-1-1 services ("Enhanced 9-1-1 or E9-1-1"), which also provide
the caller's telephone number and location to the call taker at the PSAP. When a
caller dials 9-1-1, information about the caller's location, telephone number
and the jurisdictionally appropriate PSAP must be quickly accessed from
carriers' network and mission-critical data servers. Carriers need current,
accurate information about their subscribers in order to facilitate a prompt
response to a 9-1-1 call. Each service order received by a carrier and each
change in PSAP jurisdiction, including expansion to accommodate new addresses,
may affect the information required for the proper handling of a 9-1-1 call.
Thus, delivery of 9-1-1 service presents a difficult OSS challenge for carriers
because it requires the coordination of data from multiple sources, the review
and processing of the data, the resolution of data errors and conflicts and the
insertion of the data into network and mission-critical data servers.
 
     Today, 9-1-1 is a fundamental element of local exchange service and
carriers' OSS infrastructure. According to the National Emergency Number
Association, more than 85% of the current wireline telephone subscribers in the
United States are covered by some type of 9-1-1 service and 95% of that coverage
is E9-1-1 service. The provisioning of 9-1-1 services presents even greater
challenges for wireless carriers, since the mobility of wireless callers makes
the callers' locations difficult to determine. The Cellular Telephone
Information Association estimates that approximately 83,000 9-1-1 calls are made
each day from wireless phones, representing approximately 25% of all 9-1-1
calls. The Company believes that approximately 25% of wireless callers cannot
identify their locations. Most of the existing wireless infrastructure requires
modification to enhance the location data so that wireless calls can be
accurately routed to the appropriate PSAP. Recognizing the public safety need
for improved wireless 9-1-1 services, the Federal Communications Commission (the
"FCC") issued Report & Order 94-102 (the "Order") on June 12, 1996, a directive
that mandated the adoption of 9-1-1 technology by wireless carriers in two
phases. Phase I required wireless carriers to provide to requesting PSAPs at the
time of a 9-1-1 call, the caller's telephone number and location of the
receiving cell site. Wireless carriers had to comply with Phase I mandates by
the later of April 1, 1998, or six months after the PSAP request. Phase II
requires wireless carriers to locate a 9-1-1 caller to within 125 meters,
subject to FCC guidelines. Wireless carriers must comply with Phase II mandates
for requesting PSAPs by October 1, 2001. The FCC wireless mandates, the wireless
industry's desire to continue to improve emergency services and increasing
pressure from public safety agencies have rapidly accelerated the demand for
E9-1-1 wireless services.
 
     ILECs, CLECs and wireless carriers require a 9-1-1 solution that cost
effectively provides a high degree of data integrity and reliability, allows
them to comply with regulatory mandates, and addresses their need to provide
additional value-added services. ILECs are seeking to reduce the significant
capital expenditures associated with supporting rapidly evolving 9-1-1
infrastructure and upgrading their 9-1-1 data management and network control
services to meet PSAP requirements and technological advancements. CLECs and
wireless carriers, many of which are relatively small and new to the markets in
which they are now competing, are seeking to increase their own subscriber bases
while minimizing their investment in OSS technology infrastructure and
personnel, as well as in the relationships with PSAPs necessary to provide 9-1-1
service. ILECs, CLECs and wireless carriers are also seeking a comprehensive
9-1-1 solution that effectively operates in multiple geographic locations over a
wide variety of legacy systems. In addition, the 9-1-1 OSS services
 
                                       31
<PAGE>   34
 
offered by carriers and other service providers increasingly include
complementary add-on products and services, such as public warning services,
that enable them to reduce costs and generate value-added services for their
customers. Carriers with these requirements may choose to develop their own
proprietary solutions, to license the 9-1-1 OSS software and manage the delivery
of the 9-1-1 services themselves, or to outsource their 9-1-1 OSS needs.
 
THE SCC SOLUTION
 
     The Company has redefined the U.S. market for 9-1-1 OSS by creating the
first and largest 9-1-1 service bureau, the SCC National Data Services Center,
with over 70 million subscriber data records under management throughout North
America. Through its NDSC, the Company offers a comprehensive, cost-effective
solution to the 9-1-1 service provisioning needs of ILECs, CLECs and wireless
carriers by enabling them to outsource virtually all aspects of the operations
of their 9-1-1 data management services, including system activation, routine
data administration, event transaction processing and performance management,
with a high level of security and survivability. The Company delivers an
outsourcing solution that can interface with each carrier's proprietary or open
system. In addition, the Company licenses its 9-1-1 OSS software to carriers
that wish to control the delivery of 9-1-1 services in-house. The Company
believes that its solution offers the following principal features and benefits:
 
          Focus on Data Integrity. The accuracy of subscriber records that
     identify and provide location information regarding the caller is an
     essential element of 9-1-1 service. Using its software solution, SCC
     conducts more than 60 logical tests to prepare the data for use in 9-1-1
     operations. The Company's systems interface with other elements of a
     carrier's OSS to provide timely and accurate subscriber location
     information. Transactions identified by the system as requiring further
     analysis are researched and resolved by a team of data integrity analysts.
 
          Survivability and Reliability. SCC offers large scale,
     mission-critical transaction processing through reliable, scalable
     operating platforms. To provide high assurance of continued service, SCC
     has designed systems that provide critical 9-1-1 data with multiple layers
     of redundancy by deploying over 20 fault-tolerant, geographically dispersed
     servers to provide multiple sources of 9-1-1 data. Since the launch of its
     NDSC more than three years ago, SCC's systems for 9-1-1 information
     delivery have provided uninterrupted service to its customers. SCC has also
     developed a comprehensive disaster recovery program for its central data
     administration operations.
 
          Leading-Edge Technology. The Company believes it is the technological
     leader in the 9-1-1 data management services industry based on its advances
     in the areas of systems architecture, spatial data management and advanced
     network integration. The Company's innovations include advance intelligent
     call routing support, local number portability ("LNP") data transaction
     support, technologies that improve 9-1-1 availability, a transaction-based
     map maintenance system, a spatial coordinate-based E9-1-1 management system
     and large-scale Internet applications for E9-1-1. The Company was the first
     to demonstrate data management support capable of interfacing with wireless
     systems that complied with both the Phase I and Phase II mandates of the
     Order, and also has developed systems for the use of spatial coordinate
     data for use in managing and routing non-address specific 9-1-1 calls.
 
          Flexible Business Model. PSAPs generally pay carriers a capitated rate
     based on the number of subscribers located in a particular PSAP's
     jurisdiction. By outsourcing its data management and service provisioning
     needs to the Company, a carrier can avoid costly capital expenditures and
     fix its expenses for 9-1-1 services on a per subscriber basis.
     Additionally, outsourcing allows carriers to customize their service
     packages both to meet the needs of their subscribers and to comply with
     regulatory mandates. The Company provides CLECs and wireless carriers with
     clearinghouse services to format and insert subscriber data into the
     appropriate 9-1-1 systems. Alternatively, carriers may elect to license
     9-1-1 OSS software directly from the Company and manage the 9-1-1 data
     themselves.

STRATEGY
 
     The Company's objective is to be the leading national provider of 9-1-1 OSS
and other complementary services to ILECs, CLECs and wireless carriers. SCC
focuses on developing innovative and automated solutions to provide customers
with a comprehensive system for managing large amounts of dynamic subscriber
information. Key elements of the Company's strategy are to:
 
          Maintain and Extend Leadership Position in Wireline 9-1-1 Data
     Management Market. SCC currently manages more than 70 million wireline
     subscriber data records out of an estimated 178 million total wireline
     telephone subscriber records in the United States. The Company intends to
     maintain and extend its market leadership in the wireline 9-1-1 OSS systems
     market by adding new service and license customers, increasing the number
     of subscriber data records under management, enhancing its existing 9-1-1
     services and supporting the evolving telecommunications infrastructure.
 
          Capitalize on Emerging Wireless Carrier Opportunities. The Company
     believes there is a significant opportunity to offer outsourcing services
     to wireless carriers given the growing public demand for effective wireless
     9-1-1 services and the FCC mandates for minimum service performance. The
     Company intends to take advantage of this opportunity by leveraging its
     position as the first company to offer both Phase I and Phase II compliant
     solutions and its large market share in both the wireline and wireless data
     management services industry.
 
          Maintain and Extend Leadership Position in National Clearinghouse
     Services. The Company believes opportunities exist to sell 9-1-1
     clearinghouse services to CLECs which, in order to activate 9-1-1 service
     for their customers, must provide subscriber and network information that
     is compatible with an ILEC's 9-1-1 OSS. CLECs and wireless carriers, many
     of which are relatively small and new to the markets in which they are now
     competing, are seeking to grow their own subscriber bases while minimizing
     their investment in OSS technology infrastructure and personnel, as well as
     in the relationships with PSAPs and other service providers necessary to
     provide 9-1-1 services. SCC plans to build upon its position as a neutral,
     carrier-independent service provider by working cooperatively with newly
     emerging dial tone providers, including CLECs, fixed-position wireless
     carriers and cable television carriers, to increase its sales of 9-1-1
     clearinghouse services.
 
          Provide Additional Services to Telecommunications Carriers. ILECs,
     CLECs and wireless carriers are seeking to apply emerging technologies in
     response to competitive pressures and regulatory mandates. For example, the
     Company has developed off-switch routing capabilities for carriers that
     have deployed the advanced intelligent network and created LNP transaction
     sets in response to the LNP mandates of the 1996 Act. By leveraging the
     experience and economies of scale it has obtained in managing the 9-1-1 OSS
     infrastructure for multiple carriers, the Company is well-positioned to
     continue to develop and offer flexible, scalable solutions that allow
     carriers to cost-effectively support new technological developments and
     regulatory mandates.
 
          Develop Applications for New Commercial Products. By leveraging its
     core competency of managing dynamic subscriber location information, the
     Company believes that it is well-positioned to expand into additional
     markets outside 9-1-1 OSS services. The Company currently has under
     development new products and services such as dynamic call routing for
     multi-location call centers for both telecommunications carriers and others
     and improved address information for operations areas of telecommunications
     carriers such as their billing, ordering and provisioning departments.
 
          Expand International Operations. SCC believes that a significant
     opportunity to generate additional long-term revenue may be created by
     partnering with established telecommunications carriers and systems
     integration firms to design, implement, maintain and operate effective,
     reliable emergency communications systems in countries other than the
     United States or Canada. The Company intends to expand internationally to
     address the needs of this market for telecommunications emergency services.
 
There can be no assurance that the Company will achieve its objective or any of
the key elements of its strategy. See "Risk Factors."

SERVICES AND PRODUCTS
 
     SCC's 9-1-1 OSS solution enables a 9-1-1 call to be routed to the
appropriate PSAP along with accurate and timely information about the caller's
identification and location. Complex data screening and preparation is completed
to initialize properly the underlying systems necessary for 9-1-1 call routing
and information display for the call taker. SCC's NDSC frequently receives and
processes electronic transmissions from ILECs, CLECs and wireless carriers
detailing subscriber and coverage updates and public safety jurisdiction
boundary changes from PSAPs. Records identified as potentially having problems
are automatically separated for manual review and analysis by SCC data integrity
analysts. Using the updated information, SCC's 9-1-1 OSS then provides the
information to route the 9-1-1 call and transmit essential information to the
emergency service provider.

BASE SERVICES OF SCC NATIONAL DATA SERVICES CENTER
 
     Through SCC's NDSC, the Company provides the data management services that
ILECs, CLECs and wireless carriers need to deliver 9-1-1 calls to the
appropriate PSAP, along with critical information such as caller location and
call-back number that PSAPs need to respond effectively to emergencies. Services
include:
 
          System Preparation and Administration. Before providing 9-1-1 data
     management services to its customers, SCC must collect, organize, review
     and analyze the data necessary to initialize the system properly. Data
     preparation includes collecting information on PSAP jurisdictional
     boundaries, performing a full inventory of addresses located in an area and
     loading the subscriber information into the Company's systems. To improve
     data quality and, therefore, 9-1-1 service, the Company performs diagnostic
     reviews and analyses of information loaded into the NDSC systems. SCC
     engages over 80 data integrity analysts to facilitate the creation,
     maintenance and transition of key information.
 
          Routine Data Administration. SCC's NDSC receives and automatically
     processes service order updates from ILECs, CLECs and wireless carriers on
     a regular basis, in order to maintain current data in the 9-1-1 OSS.
     Service order updates include address changes, telephone number changes and
     other information pertinent to 9-1-1 call processing. To maintain reliable
     9-1-1 service, SCC usually receives between 100,000 and 500,000 service
     orders per day and frequently receives boundary updates from PSAPs
     reflecting changes in jurisdiction boundaries for PSAP responses. When SCC
     receives a service order update or jurisdiction change, information
     received must be checked for complete and appropriate data, and then
     distributed throughout SCC's network of geographically dispersed servers.
 
          Event Transaction Processing. When a caller dials 9-1-1 in an area
     served by the Company, a request for information is automatically generated
     by the PSAP answering the call and sent to one of the Company's
     fault-tolerant servers. The server rapidly responds to the call taker with
     information from the OSS database regarding the caller's location and
     call-back number. Automated support is also available for real-time switch
     control to direct the routing of the call.
 
          Performance Management. SCC monitors and reports the performance of
     its service operations by measuring response time, systems availability,
     data accuracy and error resolution intervals, among other performance
     measurements. Using these measurements as a basis, SCC designs and
     implements programs to improve continuously the 9-1-1 OSS services provided
     by its NDSC.
 
          Mapping Services. Since traditional mapping services do not provide
     the frequent updates necessary for the provision of emergency services, SCC
     maintains a team of geographic information system experts, who work with
     carriers and public safety officials to document, review and analyze call
     routing boundaries and specific address information. The mapping services
     department uses advanced tools to improve existing mapping information with
     new and more detailed geographical information for optimal management of
     9-1-1 call records. The mapping services department also assists in system
     preparation and quality control programs to provide the SCC's NDSC with
     current geographical information.
 
          Clearinghouse Services. SCC's clearinghouse department provides a
     single point of contact to process and format 9-1-1 data for CLECs and
     independent telephone companies. CLECs and independent telephone companies
     can utilize the services of the Company's clearinghouse department to offer
     service in numerous localities without having to independently develop the
     9-1-1 OSS systems, procedures and expertise necessary for each community.
     CLECs and independent telephone companies electronically transmit
     subscriber information to the clearinghouse department. The information is
     then reformatted to comply with the destination community's local
     standards, tested for detectable errors and delivered to the appropriate
     9-1-1 data systems. The Company can process information for its
     clearinghouse customers even if the data will be inserted in a system
     operated by a carrier that does not utilize the Company's services or
     products.

ENHANCED SERVICES OF SCC NATIONAL DATA SERVICES CENTER
 
     The Company offers enhancements to its 9-1-1 OSS services that provide
additional features and functionality. These services are targeted to specific
markets and are sold directly by the Company or indirectly through the Company's
customers.
 
     9-1-1Net. 9-1-1Net, an online tool, creates an active communication channel
serving the NDSC, carriers and PSAPs. Through 9-1-1Net, users can view live
address routing rules, send address updates, review inbound call load, error
statistics and ALI discrepancy reports, and receive new product updates.
 
     Private Switch ALI. Private telephone switches, commonly known as PBX's,
create a challenge for E9-1-1 operations because information describing the
individual caller's phone station or extension within a PBX may not be available
to the network receiving the 9-1-1 call. In the case of large facilities such as
campuses, hotels and hospitals, emergency response personnel may not have
adequate information to quickly determine the location of the caller. Private
Switch ALI allows PBX system managers to create and transmit appropriate data
records that identify a caller's extension or location within a facility for the
9-1-1 OSS.
 
     9-1-1Connect. SCC provides wireless carriers with 9-1-1 OSS services that
are similar to those provided to wireline customers and that fully comply with
Phase I of the Order. Once a wireless carrier receives a request from a PSAP to
activate wireless 9-1-1 services, SCC's program managers develop a plan with the
wireless carrier to activate service, including development of ILEC network
interconnections for both data and voice that are specific to the local wireless
network configuration and interface requirements. The program managers develop
graphic coverage area maps that are superimposed on maps of current public
safety agency boundaries. Routing recommendations can then be made and
coordinated with the appropriate PSAP.
 
     Subscriber ALI. The Company is currently preparing to test Subscriber ALI,
which is designed to allow subscribers to supply personal information in their
9-1-1 records such as medical condition, disability and language of choice. When
a subscriber calls 9-1-1, data previously provided by the subscriber will be
displayed along with traditional 9-1-1 information to the PSAP. A subscriber
also can designate a third party to be notified in the event a 9-1-1 call is
initiated from the subscriber's telephone. For example, parents away from home
would be notified when a child or babysitter calls 9-1-1 from their telephone.
The Company currently anticipates that this service will be available by late
1998.
 
     Emergency Warning and Evacuation System. The Company is currently
developing its Emergency Warning and Evacuation System to initiate outbound
calls selectively in the event of potential disasters such as flash flooding,
hazardous materials incidents, industrial accidents and localized weather
events. The Emergency Warning and Evacuation System will utilize spatially
classified location information and up-to-date telephone subscriber data and
will be able to deliver voice or fax warnings to a geographically targeted
population. SCC intends to offer its Emergency Warning and Evacuation System by
late 1998.
 
LICENSE PRODUCTS
 
     The Company offers 9-1-1 OSS software to customers that elect to manage
their own 9-1-1 data records rather than outsourcing such operations to SCC. SCC
also provides custom software development services to customers with specific or
local requirements through its engineering department. The engineering
department develops, customizes and enhances the software using a structured
approach to perform requirements analysis, software development and quality
assurance.
 
COMMERCIAL SERVICES
 
     Many of the underlying elements used by the Company in managing large
volumes of dynamic subscriber information have commercial applications in other
industries. For instance, the Company has developed and is testing a dynamic
call routing system that will allow telecommunications carriers to support
real-time assignment of routing destinations for calls processed in public
telecommunications networks. Historically, calls have been routed pursuant to
preplanned and preprogrammed routing instructions. The Company's dynamic call
assignment will allow greater flexibility in call routing to respond to call
load or other complex non-network factors. The Company also intends to offer
improved address information to other operations
 
                                       36
<PAGE>   39
 
areas of telecommunications carriers such as their billing, ordering and
provisioning departments. Carriers can increase efficiencies and improve
customer service by responding to service calls with more accurate subscriber
location information.
 
SERVICE AND PRODUCT PRICING
 
     Pricing for SCC's NDSC services usually includes a non-recurring initial
fee due upon execution of a contract with a customer. Thereafter, customers
generally pay a monthly fee based on the number of subscriber records maintained
by the NDSC and upon the services selected by the customer. The Company
typically enters into ten-year agreements for wireline base services and two to
five-year agreements for wireless base services. During the contract term, SCC
may offer customers enhanced services, which may be provided on a revenue
sharing basis. SCC also licenses software, hardware and professional services
necessary for the management of 9-1-1 services to its customers in exchange for
license and implementation services fees and maintenance fees.
 
SERVICE INFRASTRUCTURE AND ARCHITECTURE
 
     The Company's operations include central data administration and
distributed systems for real-time 9-1-1 transaction support. Based on large
scale, fault-tolerant Tandem computers, the Company's major processing systems
are configured to provide high reliability. They are also designed to provide
significant capacity for continued growth using the Tandem NSK scalable
message-based architecture.
 
     The Company's central data administration systems, located in Boulder,
Colorado, are a key element of its 9-1-1 OSS, and are used to perform routine
data maintenance and to support new customer transition and initial system
loads. SCC's NDSC also maintains a central monitoring facility in Boulder that
operates 24 hours a day, seven days a week. Data network access for the central
administration systems is provided using traditional T-1 connectivity to the
networks operated by SCC and its customers. To improve reliability and
survivability, the primary links are designed to have three or more backup paths
to access SCC's distributed networks, including VSAT satellite links. A
"hot-site" emergency business recovery facility has been established in New York
and can be activated to continue routine operations in the event of a disaster
at the Boulder site. Electronic processing necessary to handle actual 9-1-1
calls is geographically distributed and remains a local service for each region,
so SCC's central data administration systems are not in the actual 9-1-1 call
path.
 
     Distributed throughout the U.S., the Company's real-time 9-1-1 OSS servers
are located in shared, hardened computer facilities. The systems are deployed in
pairs or quads. System pairs are intentionally distributed to different
geographic locations to provide an additional level of reliability. These
systems provide data display for thousands of public safety agencies throughout
the service areas of SCC's customers. Direct interface to telephone control
switches is also supported on these platforms, providing the information
necessary to route calls to the jurisdictionally appropriate PSAP. The Company
also uses a number of Microsoft NT servers for internal administrative
processing and extranet support.
 
CUSTOMERS
 
   
     The Company provides its services to a range of telecommunications service
providers, including ILECs, CLECs and wireless carriers. The Company also
licenses its software and provides 9-1-1 data clearinghouse services directly
and indirectly to over 600 independent telephone companies. During the year
ended December 31, 1996, the Company recognized approximately 82% of total
revenue from continuing operations from Ameritech and U.S. WEST, each of which
accounted for greater than 10% of the Company's revenue in such periods. During
the year ended December 31, 1997, the Company recognized approximately 81% of
total revenue from Ameritech, BellSouth Inc. and U.S. WEST customers, each of
which accounted for greater than 10% of the Company's revenue in such period.
During the three months ended March 31, 1998, the Company recognized
approximately 92% of total revenue from Ameritech, AT&T, BellSouth Inc. and U.S.
WEST customers, each of which accounted for greater than 10% of the Company's
revenue in such period. No other customers accounted for more than 10% of the
Company's total revenue in such periods. See "Risk Factors -- Reliance on
Significant Customers."

     The Company typically enters into contracts with carriers and their
affiliates to provide services to some or all of the carrier's operating
entities. Set forth below is a list of carriers utilizing the Company's services
or products, which the Company believes are representative of the Company's
overall customer base.
 
     ILECs. The Company's customers include Ameritech, BellSouth Inc. and U.S.
WEST.
 
     CLECs. The Company's customers include ICG Telecom, MCI and Worldcom
Network SVCS.
 
     Wireless Carriers. The Company's customers include 3608 Communications
Company, AT&T Wireless Services, Sprint PCS, U.S. WEST Wireless and Vanguard
Cellular Systems.
 
     License Customers. The Company's license customers include Bell Atlantic,
Bell Canada, Pacific Bell and GTE Network Services.
 
SALES AND MARKETING
 
     The Company's marketing efforts are focused on targeting key carriers and
PSAPs in each geographical market through advertising in telecommunications
industry publications, participation in trade shows, presentations at technical
conferences and other initiatives. Additionally, SCC employees serve as the
chairpersons and members of key standards committees related to emergency
communications services. The Company's sales strategy relies on direct channels
of distribution for its services. The Company has dedicated account teams to
work with each existing and potential customer. The Company's account teams
develop relationships with 9-1-1 service providers through a consultative,
problem-solving sales process and work closely with customers and potential
customers to determine how their needs can be fulfilled by the Company's
services. As of April 30, 1998, the Company employed 18 persons in its sales and
marketing organization. Sales cycles range from six months to over two years.
See "Risk Factors -- Significant Fluctuations in Quarterly Results of
Operations" and "-- Lengthy Sales Cycle."
 
RESEARCH AND DEVELOPMENT
 
     The Company directs its research and development efforts toward providing
highly scalable applications that enable a more efficient 9-1-1 OSS process that
improves data quality. Development efforts currently in process are focused on
further embedding and using spatial coordinate data to manage geographic
assignment and other data, further enhancing the Company's wireless offerings.
These offerings include improving the Company's software, integrating standard
Web browser technology, and the development of decision support systems. By late
1998, the Company expects to introduce Subscriber ALI, which will allow
subscribers to append medical and other important data to their ALI record, and
Emergency Warning and Evacuation System, which will allow PSAPs to call all
numbers in a given area and warn of imminent danger. Research and development
expenses totaled approximately $338,000, $230,000 and $738,000 for December 31,
1995, 1996, and 1997, respectively. See "-- Products and Services -- Enhanced
Services of SCC National Data Services Center" and "Risk Factors -- Dependence
on New Products; Rapid Technological Change."
 
COMPETITION
 
     The market for 9-1-1 OSS solutions is intensely competitive and the Company
expects competition to increase in the future. The Company believes that the
principal competitive factors affecting the market for 9-1-1 OSS solutions
include effectiveness with existing infrastructure, reliability, manageability,
technical features, wireless support, performance, ease of use, price, scope of
product offerings, and customer service and support. Although the Company
believes that its solution competes favorably with respect to such factors,
there can be no assurance that the Company can maintain its competitive position
against current and potential competitors, especially those with significantly
greater financial, marketing, service support, technical and other competitive
resources.
 
     The Company's principal competitors generally fall within one of three
categories: internal development departments of major carriers or consulting
firms that support such departments; relatively smaller companies that offer
applications with limited scope; and larger companies that are either in the
process of entering the Company's market or have the potential to develop
products and services that compete with the Company's
 
                                       38
<PAGE>   41
 
service offerings. Potential customers sometimes rely on their own internal
development teams to formulate 9-1-1 OSS systems or to retain consultants to
undertake such a project. The Company believes that its 9-1-1 OSS solution
competes favorably with internally developed systems, which are expensive to
develop and maintain, may not provide a comprehensive, reliable approach to
9-1-1 OSS services, and may not provide the flexibility to adapt readily to
regulatory, technological and market changes.
 
     In addition, a number of companies currently market or have under
development software products and services to provide 9-1-1 administration. The
Company competes with a few smaller companies, including XYPoint Corporation,
for the provision of 9-1-1 OSS services to wireless carriers, although the
Company expects more significant competition to emerge in the future. The
Company believes that, to date, none of these relatively smaller companies offer
products or services that are as robust in features or as comprehensive in scope
as the Company's products and services. Although it is likely that the product
development efforts of these companies eventually will enable them to offer a
line of products or services to compete with the Company's current service
offerings, the Company intends to continue to dedicate significant resources for
product and service development in order to expand the Company's capabilities
ahead of these competitors. Notwithstanding, the Company expects additional
competition from these established competitors and from other emerging
companies. Mergers or consolidations among these competitors or acquisitions of
these companies by larger competitors would make them more formidable
competitors to the Company. There can be no assurance that the Company's current
and potential competitors will not develop products and services that may be
more effective than the Company's current or future 9-1-1 data management
solutions or that the Company's technologies and offerings will not be rendered
obsolete by such developments.
 
     Finally, there are a number of companies that currently market and sell
various products and services to telecommunications carriers, such as billing
software and advanced telecommunications equipment, that have been broadly
adopted by the Company's customers and potential customers. In addition, vendors
of telecommunications software and hardware in the future may enhance their
products to include functionality that is currently provided by the Company's
solutions. The widespread inclusion of the functionality of the Company's
service offerings as standard features of other telecommunications software or
hardware could render the Company's services obsolete and unmarketable,
particularly if the quality of such functionality were comparable to that of the
Company's services. Furthermore, even if the 9-1-1 functionality provided as
standard features by telecommunications software or networking hardware is more
limited than that of the Company's services, there can be no assurance that a
significant number of customers would not elect to accept more limited
functionality in lieu of purchasing additional products or services. For
example, Lucent Technologies offers carriers software systems with functionality
similar to the Company's services. Many of these larger companies have longer
operating histories, greater name recognition, accesses to larger customer bases
and significantly greater financial, technical and marketing resources than the
Company. As a result, they 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 and services, than the
Company. The Company believes that the entry of these larger companies into its
market will require them to undertake operations that are currently not within
their core areas of expertise, and thus expose them to significant uncertainties
in the product development process or in providing a range of products and
services to comprehensively address the 9-1-1 requirements which the Company's
services addresses. However, if these companies were to introduce products or
services that effectively compete with the Company's service offerings, they
could be in a position to substantially lower the price of their 9-1-1 products
and services or to bundle such products and services with their other product
and service offerings.
 
     For the foregoing reasons, there can be no assurance that the Company will
be able to compete successfully against its current and future competitors.
Increased competition may result in price reductions, reduced gross margins and
loss of market share, any of which would materially and adversely affect the
Company's business, financial condition and results of operations. See "Risk
Factors -- Highly Competitive Market; Competition."

PROPRIETARY RIGHTS
 
     The Company's success and its ability to compete depends significantly upon
its proprietary rights. The Company relies primarily on a combination of
copyright, trademark and trade secret laws, as well as confidentiality
procedures and contractual restrictions to establish and protect its proprietary
rights. There can be no assurance that such measures will be adequate to protect
the Company's proprietary rights. Further, the Company may be subject to
additional risks as it enters into transactions in foreign countries where
intellectual property laws are not well developed or are difficult to enforce.
Legal protections of the Company's proprietary rights may be ineffective in such
countries. Litigation to defend and enforce the Company's intellectual property
rights could result in substantial costs and diversion of resources, and could
have a material adverse effect on the Company's business, financial condition
and results of operations, regardless of the final outcome of such litigation.
Despite the Company's efforts to safeguard and maintain its proprietary rights
both in the United States and abroad, there can be no assurance that the Company
will be successful in doing so or that the steps taken by the Company in this
regard will be adequate to deter misappropriation or independent third-party
development of the Company's technology, or to prevent an unauthorized third
party from copying or otherwise obtaining and using the Company's technology.
There also can be no assurance that others will not independently develop
similar technologies or duplicate any technology developed by the Company. Any
such events could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     As the number of entrants to the Company's markets increases and the
functionality of the Company's products and services increases and overlaps with
the products and services of other companies, the Company may become subject to
claims of infringement or misappropriation of the intellectual property rights
of others. In certain of its customer agreements, the Company agrees to
indemnify its customers for any expenses or liabilities resulting from claimed
infringements of patents, trademarks or copyrights of third parties. In certain
limited instances, the amount of such indemnities may be greater than the
revenue the Company may have received from the customer. There can be no
assurance that third parties will not assert infringement or misappropriation
claims against the Company in the future with respect to current or future
products or services. Any claims or litigation, with or without merit, could be
time consuming, result in costly litigation or require the Company to enter into
royalty or licensing arrangements. Such royalty or licensing arrangements, if
required, may not be available on terms acceptable to the Company, if at all,
and could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
EMPLOYEES
 
     As of April 30, 1998, the Company employed 249 full-time employees in eight
states. Of these employees, 34 were involved in research and development, 18 in
sales and marketing, 165 in technical support and operations and 32 in
administration and finance. No employees are covered by any collective
bargaining agreements. The Company believes that its relationships with its
employees are good.
 
FACILITIES
 
     The Company's principal administrative, sales and marketing, research and
development and support facilities consist of approximately 80,000 square feet
of office space in Boulder, Colorado. The Company occupies these premises under
a lease expiring December 31, 2002. As of March 31, 1998, the annual base rent
for this facility was approximately $670,000; however, the lease agreement
provides for periodic defined increases in rent through the lease term.
 
LEGAL PROCEEDINGS
 
     The Company is not a party to any litigation that it believes could have a
material adverse effect on the Company or its business.

     The Compensation Committee of the Company's Board was formed in 1995, and
the current members of the Compensation Committee are John G. Hill and Darrell
Williams. Prior to April 1998, George K. Heinrichs and Mr. Hill were the members
of the Compensation Committee. Throughout the year ended December 31, 1997, Mr.
Heinrichs was an officer of the Company. No executive officer of the Company
serves as a member of the Board of Directors or Compensation Committee of any
entity that has one or more executive officers serving as a member of the
Company's Board of Directors or Compensation Committee.
 
DIRECTOR COMPENSATION
 
     Directors currently are not compensated for serving on the Board of
Directors. The Company reimburses its directors for all reasonable and necessary
travel and other incidental expenses incurred in connection with their
attendance at meetings of the Board of Directors. The Company has not previously
granted non-employee Board members options to purchase shares of Common Stock,
although the Company may grant options to its non-employee directors in the
future at the discretion of the Board. See "-- Benefit Plans -- 1998 Stock
Incentive Plan."
 
BENEFIT PLANS
 
  1998 Stock Incentive Plan
 
     The Company's 1998 Stock Incentive Plan (the "1998 Plan") is intended to
serve as the successor equity incentive program to the Company's 1990 Stock
Option Plan, as amended (the "Predecessor Plan"). The 1998 Plan was adopted by
the Board and the stockholders on April 7, 1998 (the "Plan Effective Date").
 
     A total of 1,901,055 shares of Common Stock have been authorized for
issuance under the 1998 Plan. Such share reserve consists of (i) the number of
shares available for issuance under the Predecessor Plan on April 7, 1998,
including the shares subject to outstanding options and (ii) an additional
increase of approximately 500,000 shares. In addition, the share reserve will
automatically be increased on the first trading day of each calendar year,
beginning with the 1999 calendar year, by an amount equal to 3% of the total
number of shares of Common Stock outstanding on the last trading day in December
of the immediately preceding calendar year, but in no event shall any such
annual increase exceed 731,000 shares. To the extent any unvested shares of
Common Stock issued under the Predecessor Plan are repurchased by the Company
after the date on which the Common Stock is first registered under Section 12 of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), at the
exercise price paid per share, in connection with the holder's termination of
service, those repurchased shares will be added to the reserve of Common Stock
available for issuance under the 1998 Plan, but in no event shall more than
476,776 shares be added to the reserve from such repurchases. In no event may
any one participant in the 1998 Plan receive option grants,
 
                                       43
<PAGE>   46
 
separately exercisable stock appreciation rights or direct stock issuances for
more than 500,000 shares of Common Stock in the aggregate per calendar year.
 
     On the date on which the Common Stock is first registered under Section 12
of the Exchange Act, outstanding options issued under the Predecessor Plan will
be incorporated into the 1998 Plan, and no further option grants will be made
under the Predecessor Plan. The incorporated options will continue to be
governed by their existing terms, unless the Plan Administrator elects to extend
one or more features of the 1998 Plan to those options. Except as otherwise
noted below, the incorporated options have substantially the same terms as will
be in effect for grants made under the Discretionary Option Grant Program of the
1998 Plan.
 
     The 1998 Plan is divided into five separate components: (i) the
Discretionary Option Grant Program, under which eligible individuals in the
Company's employ or service (including officers, non-employee Board members and
consultants) may, in the Plan Administrator's discretion, be granted options to
purchase shares of Common Stock at an exercise price not less than their fair
market value on the grant date; (ii) the Stock Issuance Program, under which
such individuals may, in the Plan Administrator's discretion, be issued shares
of Common Stock directly, through the purchase of such shares at a price not
less than their fair market value at the time of issuance or as a bonus tied to
the performance of services; (iii) the Salary Investment Option Grant Program,
which may, in the Plan Administrator's discretion, be activated for one or more
calendar years and thereby allow executive officers and other highly compensated
employees the opportunity to invest a portion of their base salary in special
below-market stock option grants; (iv) the Automatic Option Grant Program, under
which option grants will automatically be made at periodic intervals to eligible
non-employee Board members to purchase shares of Common Stock at an exercise
price equal to their fair market value on the grant date; and (v) the Director
Fee Option Grant Program, which may, in the Plan Administrator's sole
discretion, be activated for one or more calendar years and thereby allows
non-employee Board members the opportunity to apply all or any portion of the
annual retainer fee otherwise payable to them in cash each year to the
acquisition of special below-market option grants. The Discretionary Option
Grant, Stock Issuance Program and Automatic Option Program become effective on
the date on which the Underwriting Agreement to be executed in connection with
this offering is executed (the "Underwriting Date"). The implementation date of
the Salary Investment Option Grant Program and the Director Fee Option Program
will be decided by the Compensation Committee.
 
     The Discretionary Option Grant Program and the Stock Issuance Program will
be administered by the Compensation Committee. The Compensation Committee as
Plan Administrator will have complete discretion to determine which eligible
individuals are to receive option grants or stock issuances under those
programs, the time or times when such option grants or stock issuances are to be
made, the number of shares subject to each such grant or issuance, the status of
any granted option as either an incentive stock option or a non-statutory stock
option under the Federal tax laws, the vesting schedule to be in effect for the
option grant or stock issuance, and the maximum term for which any granted
option is to remain outstanding. The Compensation Committee will also have the
exclusive authority to select the executive officers and other highly
compensated employees who may participate in the Salary Investment Option Grant
Program in the event that program is activated for one or more calendar years,
but neither the Compensation Committee nor the Board will exercise any
administrative discretion with respect to option grants made under the Salary
Investment Option Grant Program or under the Automatic Option Grant or Director
Fee Option Grant Program for the non-employee Board members.
 
     In the event the Plan Administrator elects to activate the Salary
Investment Option Grant Program for one or more calendar years, each executive
officer and other highly compensated employee of the Company selected for
participation may elect, prior to the start of the calendar year, to reduce his
or her base salary for that calendar year by a specified dollar amount not less
than $10,000 nor more than $50,000. If such election is approved by the Plan
Administrator, the individual will automatically be granted, on the first
trading day in January of the calendar year for which that salary reduction is
to be in effect, a non-statutory option to purchase that number of shares of
Common Stock determined by dividing the salary reduction amount by two-thirds of
the fair market value per share of Common Stock on the grant date. The option
will be exercisable at a price per share equal to one-third of the fair market
value of the option shares on the grant date. As a result, the total spread on
the option shares at the time of grant (the fair market value of the option
shares on the grant date less the aggregate exercise price payable for those
shares) will be equal to the amount
 
                                       44
<PAGE>   47
 
of salary invested in that option. The option will vest in a series of 12 equal
monthly installments over the calendar year for which the salary reduction is to
be in effect and will be subject to full and immediate vesting upon certain
changes in the ownership or control of the Company.
 
     The Company has not previously granted non-employee Board members options
to purchase shares of Common Stock. However, under the Automatic Option Grant
Program, each individual who first becomes a non-employee Board member at any
time after the Underwriting Date will automatically be granted an option to
purchase 15,000 shares of Common Stock on the date such individual joins the
Board, provided such individual has not been in the prior employ of the Company.
In addition, on the date of each Annual Stockholders Meeting held on or after
the Underwriting Date, each non-employee Board member who is to continue to
serve as a non-employee Board member (including individuals who joined the Board
prior to the Underwriting Date) will automatically be granted an option to
purchase 3,000 shares of Common Stock, provided such individual has served on
the Board for at least six months.
 
     Each automatic grant for the non-employee Board members will have a term of
10 years, subject to earlier termination following the optionee's cessation of
Board service. Each automatic option will be immediately exercisable for all of
the option shares; however, any unvested shares purchased under the option will
be subject to repurchase by the Company, at the exercise price paid per share,
should the optionee cease Board service prior to vesting in those shares. The
shares subject to each initial 15,000 share automatic option grant will vest
over a four-year period, as follows: (i) 25% of the option shares upon the
optionee's completion of one year of Board service measured from the grant date
and (ii) the balance of the option shares in a series of 36 successive equal
monthly installments upon the optionee's completion of each additional month of
service measured from the first anniversary of the grant date. The shares
subject to each annual 3,000 share grant will vest upon the optionee's
completion of one year of Board service measured from the grant date. However,
the shares subject to each automatic option grant will immediately vest in full
upon certain changes in control or ownership of the Company or upon the
optionee's death or disability while a Board member.
 
     Should the Director Fee Option Grant Program be activated in the future,
each non-employee Board member will have the opportunity to apply all or a
portion of the annual retainer fee otherwise payable in cash to the acquisition
of a below-market option grant. The option grant will automatically be made on
the first trading day in January in the calendar year for which the retainer fee
would otherwise be payable in cash. The option will have an exercise price per
share equal to one-third of the fair market value of the option shares on the
grant date, and the number of shares subject to the option will be determined by
dividing the amount of the retainer fee applied to the program by two-thirds of
the fair market value per share of Common Stock on the grant date. As a result,
the total spread on the option (the fair market value of the option shares on
the grant date less the aggregate exercise price payable for those shares) will
be equal to the portion of the retainer fee invested in that option. The option
will become exercisable for the option shares in a series of twelve (12) equal
monthly installments over the calendar year for which the election is to be in
effect. However, the option will become immediately exercisable for all the
option shares upon (i) certain changes in the ownership or control of the
Company or (ii) the death or disability of the optionee while serving as a Board
member.
 
     The Board may amend or modify the 1998 Plan at any time, subject to any
required stockholder approval. The 1998 Plan will terminate on the earliest of
(i) April 30, 2008, (ii) the date on which all shares available for issuance
under the 1998 Plan have been issued as fully-vested shares or (iii) the
termination of all outstanding options in connection with certain changes in
control or ownership of the Company.
 
  1998 Employee Stock Purchase Plan
 
     The Company's Employee Stock Purchase Plan (the "Purchase Plan") was
adopted by the Board of Directors in March 1998 and approved by the Company's
stockholders in April 1998. A total of 200,000 shares of Common Stock have been
reserved for issuance under the Purchase Plan. There is automatically added to
the Purchase Plan in March of each year (i) that number of shares needed to
restore the maximum aggregate shares available to 200,000 shares or (ii) a
lesser amount determined by the Board. The Purchase Plan, which is intended to
qualify under Section 423 of the Code, provides for two six-month offering
periods each year beginning on the first of January and the first of July,
respectively; however, the initial offering period began on
 
                                       45
<PAGE>   48
 
March 1, 1998 and continues through December 31, 1998. The Purchase Plan is
administered by a committee of at least two disinterested Directors appointed by
the Board. Employees (including officers and employee directors) of the Company
are eligible to participate if they are employed by the Company on a regular
full time or part time basis and if they are regularly scheduled to work more
than 20 hours per week. The Purchase Plan permits eligible employees to purchase
shares of Common Stock through periodic payroll deductions at a price equal to
the lower of 85% of the fair market value of the Company's Common Stock at the
beginning or end of the offering period. Employees may end their participation
in the offering at any time during the offering period, and participation ends
automatically on termination of employment with the Company. The Board of
Directors has the power to amend or terminate the Purchase Plan as long as such
action does not adversely affect any outstanding rights to purchase stock
thereunder.
 
LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS
 
     The Company's Amended and Restated Certificate of Incorporation eliminates,
subject to certain exceptions, directors' personal liability to the Company or
its stockholders for monetary damages for breaches of fiduciary duties. The
Amended and Restated Certificate of Incorporation does not, however, eliminate
or limit the personal liability of a Director for (i) any breach of the
Director's duty of loyalty to the Company or its stockholders, (ii) acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) unlawful payments of dividends or unlawful stock
repurchases or redemptions as provided in Section 174 of the Delaware General
Corporation Law or (iv) any transaction from which the Director derived an
improper personal benefit.
 
     The Company's Restated Bylaws, which will become effective upon the closing
of this offering, provide that the Company shall indemnify its Directors and
executive officers to the fullest extent permitted under the Delaware General
Corporation Law and may indemnify its other officers, employees and other agents
as set forth in the Delaware General Corporation Law. In addition, the Company
plans to enter into indemnification agreements (the "Indemnification
Agreements") with each of its Directors and executive officers, effective upon
the effectiveness of the Registration Statement of which this Prospectus forms a
part. The indemnification agreements will contain provisions that require the
Company, among other things, to indemnify its Directors and executive officers
against certain liabilities (other than liabilities arising from intentional or
knowing and culpable violations of law) that may arise by reason of their status
or service as Directors or executive officers of the Company or other entities
to which they provide service at the request of the Company and to advance
expenses they may incur as a result of any proceeding against them as to which
they could be indemnified. The Company believes that these provisions and
agreements are desirable to attract and retain qualified Directors and officers.
The Company has obtained an insurance policy covering Directors and officers for
claims that such Directors and officers may otherwise be required to pay or for
which the Company is required to indemnify them, subject to certain exclusions.
 
EMPLOYMENT AGREEMENTS AND COMPENSATION PLAN
 
  Employment Agreements
 
     The Company does not presently have any employment contracts with the Named
Officers.
 
  Management Incentive Compensation Plan
 
     In early 1998, the Compensation Committee of the Board of Directors
approved a Management Incentive Compensation Plan, under which selected key
employees, including executive officers, are eligible to receive bonus payments.
At the beginning of the year, financial objectives were established and approved
by the Compensation Committee for each participant in the program. A minimum
performance level must be achieved by the Company before any bonus may be earned
by a participant. Thereafter, an established progression rewards higher levels
of achievement with greater bonus payments. Aggregate bonuses payable under the
Management Incentive Compensation Plan in any one year will be limited to a
pre-determined percentage of each participant's salary.

                              CERTAIN TRANSACTIONS
 
     In connection with the Company's Series F Preferred Stock Financing on
March 5, 1996, the Company and the holders of Convertible Preferred Stock
entered into a Fourth Amended and Restated Registration Rights Agreement (the
"Registration Rights Agreement"). Pursuant to the Registration Rights Agreement,
holders of Convertible Preferred Stock that will be converted into Common Stock
in connection with this offering have the right, beginning six months after the
date of this offering and subject to certain limitations and conditions, to
require the Company to file registration statements under the Securities Act to
register all or a part of their shares of Common Stock. The Company, in certain
circumstances, may defer such registrations, and the Underwriters have the
right, subject to certain limitations, to limit the number of shares included in
such registrations. In the event that the Company proposes to register any of
its securities under the Securities Act, either for its own account or for the
account of other securities holders, the holders of Convertible Preferred Stock
are entitled to include their shares of Common Stock in such registration,
subject to marketing and other limitations. Generally, the Company is required
to bear all of the expenses of such registration. Ameritech Development Corp.,
which holds in the aggregate 23.5% of the outstanding capital stock of the
Company (on an as-converted basis), The Hill Partnership III, L.P. (the "Hill
Partnership"), which holds in the aggregate 25.7% of the outstanding capital
stock of the Company (on an as-converted basis), Boston Capital Ventures Limited
Partnership and its affiliates, which hold in the aggregate 25.0% of the
outstanding capital stock of the Company (on an as-converted basis), are parties
to the Registration Rights Agreement. John G. Hill, an affiliate of The Hill
Partnership, and Darrell A. Williams, an affiliate of Ameritech Development
Corp., are Directors of the Company.
 
     The Company provides 9-1-1 OSS services pursuant to a 9-1-1 Services
Agreement dated as of August 31, 1994, as amended, between Ameritech Information
Systems, Inc. and the Company. Pursuant to a Master Lease dated as of March 11,
1996, with Ameritech Credit Corporation, the Company leases certain personal
property. Additionally, the Company is a party to a Consulting Agreement dated
October 27, 1997 with Ameritech Mobile Communications, Inc. pursuant to which
the Company performed a market survey regarding the provision of 9-1-1 service
to cellular telephone subscribers. Ameritech Information Systems, Inc.,
Ameritech Credit Corporation and Ameritech Mobile Communications, Inc. are
affiliates of Ameritech Development Corp. The Company received net proceeds of
approximately $3,226,000, $6,606,000 and $6,959,000 in 1995, 1996 and 1997,
respectively, pursuant to these agreements.
 
     The Company believes that the terms of the transactions described above
were no less favorable to the Company than would have been obtained from an
unaffiliated third party. Any future transactions between the Company and any of
its officers, Directors or principal stockholders will be on terms no less
favorable to the Company than could be obtained from unaffiliated third parties
and will be approved by a majority of the independent and disinterested members
of the Board of Directors.
 
     The Company plans to enter into the Indemnification Agreements with its
Directors and executive officers, effective upon the effectiveness of the
Registration Statement of which this Prospectus forms a part. Subject to the
provisions of the Indemnification Agreements, the Company shall indemnify and
advance expenses to such Directors and executive officers in connection with
their involvement in any event or occurrence that arises in their capacity as,
or as a result of, their positions with the Company. See
"Management -- Limitations on Liability and Indemnification Matters."

                          DESCRIPTION OF CAPITAL STOCK
 
     The Company is authorized to issue 30,000,000 shares of Common Stock, $.001
par value, and 15,000,000 shares of undesignated preferred stock, $.001 par
value (the "Preferred Stock").
 
COMMON STOCK
 
     As of April 30, 1998, there were 8,342,853 shares of Common Stock
outstanding held of record by 124 stockholders. As of April 30, 1998, options to
purchase an aggregate of 1,114,046 shares of Common Stock were also outstanding.
See "Management -- Stock Plans."
 
     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 Company is authorized to issue 15,000,000 shares of undesignated
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
stockholders. 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 stockholders 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.
 
REGISTRATION RIGHTS
 
     Under the Registration Rights Agreement, the holders of approximately
6,188,575 shares of Common Stock and their permitted transferees (the "Holders")
are entitled to certain rights with respect to the registration of such shares
("Registrable Securities") under the Securities Act. Under the terms of the
Registration Rights Agreement, the holders of at least 50% of the Registrable
Securities may require, on two occasions after six months from the effective
date of this offering, that the Company use its best efforts to register the
Registrable Securities for public resale. In addition, if the Company proposes
to register any of its securities under the Securities Act, either for its own
account or for the account of other security holders exercising registration
rights, the Holders are entitled to notice of such registration and are entitled
to include shares of such Common Stock therein. The Holders may also require the
Company on an unlimited number of occasions to register all or a portion of
their Registrable Securities on Form S-3 under the Securities Act when use of
such form becomes available to the Company. All such registration rights are
subject to certain conditions and limitations, including the right of the
underwriters of an offering to limit the number of shares to be included in such
registration. In addition, the Company need not effect a registration within six
months following a previous registration, or after such time as all Holders may
sell under Rule 144(k) all shares of Common Stock to which such registration
rights apply. See "Certain Transactions."
 
     Additionally, the holder of a warrant to purchase 195,148 shares of Common
Stock is entitled to request registration of such shares pursuant to a separate
registration rights agreement. In addition, if the Company proposes to register
any of its securities under the Securities Act, either for its own account or
for the account
 
                                       51
<PAGE>   54
 
or for other security holders exercising registration rights, the warrant holder
is entitled to notice of such registration and is entitled to include shares of
such Common Stock therein. The warrant will be exercised in full upon the
closing of this offering.
 
POSSIBLE ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER PROVISIONS
 
  Amended and Restated Certificate of Incorporation and Restated Bylaws
 
     The Company's Amended and Restated Certificate of Incorporation authorizes
the Board to establish one or more series of undesignated Preferred Stock, the
terms of which can be determined by the Board at the time of issuance. See
"-- Preferred Stock." The Amended and Restated Certificate of Incorporation also
provides that all stockholder actions must be effected at a duly called meeting
of stockholders and not by a consent in writing. In addition, effective upon the
closing of this offering, the Company's Restated Bylaws will not permit
stockholders of the Company to call a special meeting of stockholders; only the
Company's Chief Executive Officer, President or Chairperson of the Board or a
majority of the Board will be permitted to call a special meeting of
stockholders. The Restated Bylaws also will require that stockholders give
advance notice to the Company's Secretary of any nominations for Director or
other business to be brought by stockholders at any stockholders' meeting and
require a vote of 66 2/3% of the stockholders or a majority of the members of
the Board to amend the Restated Bylaws. These provisions of the Amended and
Restated Certificate of Incorporation and the Restated Bylaws could discourage
potential acquisition proposals and could delay or prevent a change in control
of the Company. Such provisions also may have the effect of preventing changes
in the management of the Company.
 
  Delaware Anti-Takeover Statute
 
     The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203"), which, subject to certain exceptions, prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholder (defined as any person or entity that is the beneficial owner of at
least 15% of a corporation's voting stock) for a period of three years following
the time that such stockholder became an interested stockholder, unless: (i)
prior to such time, the board of directors of the corporation approved either
the business combination or the transaction that resulted in the stockholder's
becoming an interested stockholder; (ii) upon consummation of the transaction
that resulted in the stockholder's becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding, for purposes of
determining the number of shares outstanding, those shares owned (x) by persons
who are directors and also officers and (y) by employee stock plans in which
employee participants do not have the right to determine confidentially whether
shares held subject to the plan will be tendered in a tender or exchange offer;
or (iii) at or subsequent to such time, the business combination is approved by
the Board and authorized at an annual or special meeting of stockholders, and
not by written consent, by the affirmative vote of at least two-thirds of the
outstanding voting stock that is not owned by the interested stockholder.
 
     Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii) any
sale, lease, exchange, mortgage, transfer, pledge or other disposition involving
the interested stockholder and 10% or more of the assets of the corporation;
(iii) subject to certain exceptions, any transaction which results in the
issuance or transfer by the corporation of any stock of the corporation to the
interested stockholder; (iv) any transaction involving the corporation that has
the effect of increasing the proportionate share of the stock of any class or
series of the corporation beneficially owned by the interested stockholder; or
(v) the receipt by the interested stockholder of the benefit of any loans,
advances, guarantees, pledges or other financial benefits provided by or through
the corporation.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon completion of this offering, there will be 10,442,007 shares of Common
Stock of the Company outstanding, based on shares outstanding as of April 9,
1998. There were also approximately 637,270 shares covered by vested options
outstanding, which are not considered to be outstanding shares. Of the
outstanding shares, 3,361,469 shares, including the 3,300,000 shares of Common
Stock sold in this offering, will be immediately eligible for resale in the
public market without restriction under the Securities Act, except that any
shares purchased in this offering by affiliates of the Company ("Affiliates"),
as that term is defined in Rule 144 under the Securities Act ("Rule 144"), may
generally only be resold in compliance with applicable provisions of Rule 144.
Beginning approximately 90 days after the date of this Prospectus, approximately
16,665 additional shares of Common Stock will become eligible for immediate
resale in the public market, subject to compliances to certain of such shares
with applicable provisions of Rules 144 and 701 under the Securities Act ("Rule
701").
    
 
   
     The Company, the executive officers and Directors of the Company, and
certain security holders of the Company have agreed pursuant to lock-up
agreements that they will not, without the prior written consent of BancAmerica
Robertson Stephens, offer, sell or otherwise dispose of the shares of Common
Stock beneficially owned by them for a period of 180 days from the date of this
Prospectus. Each holder who signed a lock-up agreement has agreed, subject to
certain limited exceptions, not to sell or otherwise dispose of any of the
shares held by them as of the date of this Prospectus for a period of 180 days
after the date of this Prospectus without the prior written consent of
BancAmerica Robertson Stephens. At the end of such 180-day period, approximately
8,706,944 shares of Common Stock (including approximately 671,040 shares
issuable upon exercise of vested options) will be eligible for immediate resale,
subject to compliance with Rule 144 and Rule 701. The remainder of the
approximately 110,068 shares of Common Stock outstanding will become eligible
for sale at various times over a period of less than two years and could be sold
earlier if the holders exercise any available registration rights or upon
vesting pursuant to the Company's standard four year vesting schedule.
Approximately an additional 442,573 shares issuable upon exercise of existing
options will become eligible for sale at various times over a period of less
than four years.
    
 
     In general, under Rule 144 beginning approximately 90 days after the
effective date of the Registration Statement of which this Prospectus is a part,
a stockholder, including an Affiliate, who has beneficially owned his or her
restricted securities (as that term is defined in Rule 144) for at least one
year from the later of the date such securities were acquired from the Company
or (if applicable) the date they were acquired from an Affiliate is entitled to
sell, within any three-month period, a number of such shares that does not
exceed the greater of one percent of the then outstanding shares of Common Stock
(approximately 104,420 shares immediately after the offering) or the average
weekly trading volume in the Common Stock during the four calendar weeks
preceding the date on which notice of such sale was filed under Rule 144,
provided certain requirements concerning availability of public information,
manner of sale and notice of sale are satisfied. In addition, under Rule 144(k),
if a period of at least two years has elapsed between the later of the date
restricted securities were acquired from the Company or (if applicable) the date
they were acquired from an Affiliate of the Company, a stockholder who is not an
Affiliate of the Company at the time of sale and has not been an Affiliate of
the Company for at least three months prior to the sale is entitled to sell the
shares immediately without compliance with the foregoing requirements under Rule
144.
 
     Securities issued in reliance on Rule 701 (such as shares of Common Stock
that may be acquired pursuant to the exercise of certain options granted prior
to this offering) are also restricted securities and, beginning 90 days after
the date of this Prospectus, may be sold by stockholders other than an Affiliate
of the Company subject only to the manner of sale provisions of Rule 144 and by
an Affiliate under Rule 144 without compliance with its one-year holding period
requirement.
 
     Prior to this offering, there has been no public market for the Common
Stock. No prediction can be made as to the effect, if any, that market sales of
shares or the availability of shares for sale will have on the market price of
the Common Stock prevailing from time to time. The Company is unable to estimate
the number of shares that may be sold in the public market pursuant to Rule 144,
since this will depend on the market price of the Common Stock, the personal
circumstances of the sellers and other factors. Nevertheless, sales of
 
                                       53
<PAGE>   56
 
significant amounts of the Common Stock of the Company in the public market
could adversely affect the market price of the Common Stock and could impair the
Company's ability to raise capital through an offering of its equity securities.
 
   
     In addition, the Company intends to register approximately 90 days after
the date of this Prospectus a total of 1,901,055 shares of Common Stock subject
to outstanding options or reserved for issuance under the Company's 1998 Plan or
outstanding shares that are subject to repurchase by the Company plus 200,000
shares of Common Stock reserved for issuance under the Purchase Plan.
Furthermore, upon expiration of lock-up agreements described above, holders of
approximately 6,383,723 shares of Common Stock will be entitled to certain
registration rights with respect to such shares. 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 could have a material adverse effect on
the market price of the Common Stock.

     The Company and the Selling Stockholders have been advised by the
Representatives that the Underwriters propose to offer the shares of Common
Stock to the public at the initial public offering price set forth on the cover
page of this Prospectus and to certain dealers at such price less a concession
not in excess of $          per share, of which $          may be reallowed to
other dealers. After the initial public offering, the public offering price,
concession and reallowance to dealers may be reduced by the Representatives. No
such reduction shall change the amount of proceeds to be received by the Company
and the Selling Stockholders as set forth on the cover page of this Prospectus.
 
     The Company and certain Selling Stockholders have granted to the
Underwriters an option, exercisable during the 30-day period after the date of
this Prospectus, to purchase up to           and           additional shares of
Common Stock, respectively, at the same price per share as the Company and the
Selling Stockholders will receive for the 3,300,000 shares that the Underwriters
have agreed to purchase. To the extent that the Underwriters exercise such
option, each of the Underwriters will have a firm commitment to purchase
approximately the same percentage of such additional shares that the number of
shares of Common Stock to be purchased by it shown in the above table represents
as a percentage of the 3,300,000 shares offered hereby. If purchased, such
additional shares will be sold by the Underwriters on the same terms as those on
which the 3,300,000 shares are being sold. The Company and such Selling
Stockholders will be obligated, pursuant to the option, to sell shares to the
extent the option is exercised. The Underwriters may exercise such option only
to cover over-allotments made in connection with the sale of shares of Common
Stock offered hereby.
 
     The Underwriting Agreement contains covenants of indemnity among the
Underwriters, the Company and the Selling Stockholders against certain civil
liabilities, including liabilities under the Securities Act and liabilities
arising from breaches of representations and warranties contained in the
Underwriting Agreement.
 
     Each officer and director and certain holders of shares of the Company's
Common Stock have agreed with the Representatives, for a period of 180 days
after the date of this Prospectus (the "Lock-Up Period"), subject to certain
exceptions, not to offer to sell, contract to sell, or otherwise sell, dispose
of, loan, pledge or grant any rights with respect to any shares of Common Stock,
any options or warrants to purchase any shares of Common Stock, or any
securities convertible into or exchangeable for shares of Common Stock owned as
of

the date of this Prospectus or thereafter acquired directly by such holders or
with respect to which they have or hereafter acquire the power of disposition,
without the prior written consent of BancAmerica Robertson Stephens. However,
BancAmerica Robertson Stephens may, in its sole discretion and at any time
without notice, release all or any portion of the securities subject to lock-up
agreements. There are no agreements between the Representatives and any of the
Company's stockholders providing consent by the Representatives to the sale of
shares prior to the expiration of the Lock-Up Period. The Company has agreed
that during the Lock-Up Period, the Company will not, subject to certain
exceptions, without the prior written consent of BancAmerica Robertson Stephens,
(i) consent to the disposition of any shares held by stockholders prior to the
expiration of the Lock-Up Period or (ii) issue, sell, contract to sell or
otherwise dispose of, any shares of Common Stock, any options or warrants to
purchase any shares of Common Stock or any securities convertible into,
exercisable for or exchangeable for shares of Common Stock, other than the
Company's sale of shares in this offering, the issuance of Common Stock upon the
exercise of outstanding options and warrants and the Company's issuance of
options and stock under the existing stock option and stock purchase plans. See
"Shares Eligible for Future Sale."
 
     The Underwriters do not intend to confirm sales to any accounts over which
they exercise discretionary authority.
 
     Prior to this offering, there has been no public market for the Common
Stock of the Company. Consequently, the initial public offering price for the
Common Stock offered hereby will be determined through negotiations between the
Company and the Representatives. Among the factors to be considered in such
negotiations are prevailing market conditions, certain financial information of
the Company, market valuations of other companies that the Company and the
Representatives believe to be comparable to the Company, estimates of the
business potential of the Company, the present state of the Company's
development and other factors deemed relevant.
 
     The Representatives have advised the Company that, pursuant to Regulation M
under the Securities Act, certain persons participating in the offering may
engage in transactions, including stabilizing bids, syndicate covering
transactions or the imposition of penalty bids, that may have the effect of
stabilizing or maintaining the market price of the Common Stock at a level above
that which might otherwise prevail in the open market. A "stabilizing bid" is a
bid for or the purchase of the Common Stock on behalf of the Underwriters for
the purpose of fixing or maintaining the price of the Common Stock. A "syndicate
covering transaction" is the bid for or the purchase of the Common Stock on
behalf of the Underwriters to reduce a short position incurred by the
Underwriters in connection with the offering. A "penalty bid" is an arrangement
permitting the Representatives to reclaim the selling concession otherwise
accruing to an Underwriter or syndicate member in connection with the offering
if the Common Stock originally sold by such Underwriter or syndicate member is
purchased by the Representatives in a syndicate covering transaction and has
therefore not been effectively placed by such Underwriter or syndicate member.
The Representatives have advised the Company that such transactions may be
effected on the Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Stockholders of SCC Communications Corp.:
 
     We have audited the accompanying balance sheets of SCC Communications Corp.
(a Delaware corporation) as of December 31, 1996 and 1997, and the related
statements of operations, stockholders' equity (deficit) and cash flows for each
of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of SCC Communications Corp. as
of December 31, 1996 and 1997, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
              (INCLUDING INFORMATION RELATED TO UNAUDITED PERIODS)

(1) ORGANIZATION, BUSINESS AND LIQUIDITY
 
     SCC Communications Corp., doing business as SCC (the "Company"), is a
Delaware corporation. The Company is the leading provider of 9-1-1 operations
support systems services to incumbent local exchange carriers, competitive local
exchange carriers and wireless carriers in the United States. The Company
manages the data which enables 9-1-1 calls to be routed to the appropriate
public safety agency with accurate and timely information about the caller's
identification and location. In addition, the Company licenses its 9-1-1
software to carriers that wish to manage the delivery of 9-1-1 data management
services in-house.
 
LIQUIDITY
 
     Although the Company had a working capital deficit at December 31, 1997,
the Company generated net income from continuing operations before income taxes
of approximately $2,455,000 while also generating positive operating cash flows
of approximately $5,400,000 in 1997. The Company believes that its operating
cash and its line of credit, which has been renewed through April 15, 1999, will
be adequate to meet its cash requirements for operations for the next twelve
months.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
OPERATING CYCLE
 
     Assets and liabilities related to contracts are included in current assets
and liabilities in the accompanying balance sheets since they will be liquidated
in the normal course of contract completion, although this may require more than
one year.
 
PROPERTY AND EQUIPMENT
 
     Depreciation of property and equipment is computed using the straight-line
method over estimated useful lives of three to five years for computer hardware
and equipment, five years for furniture and fixtures and the life of the lease
for leasehold improvements. The costs of repairs and maintenance are expensed
while enhancements to existing assets are capitalized.
 
SOFTWARE DEVELOPMENT COSTS
 
     The Company expenses the costs of developing computer software until
technological feasibility is established and capitalizes all costs incurred from
that time until the software is available for general customer release.
Technological feasibility for the Company's computer software products is based
upon the earlier of the achievement of (a) a detail program design free of
high-risk development issues or (b) completion of a working model. Costs of
major enhancements to existing products with a wide market are capitalized while
routine maintenance of existing products is charged to expense as incurred. The
establishment of technological feasibility and the ongoing assessment of the
recoverability of capitalized computer software development costs requires
considerable judgment by management with respect to certain external factors,
including, but not limited to, technological feasibility, anticipated future
gross revenues, estimated economic life and changes in software and hardware
technology.
 
     Capitalized software costs are amortized on a product-by-product basis. The
annual amortization is the greater of the amount computed using (a) the ratio
that current gross revenues for a product bear to the total of current and
anticipated future gross revenues for that product, or (b) the straight-line
method over the remaining estimated economic life of the product which is
typically five years. Accumulated amortization of capitalized software costs
from continuing operations totaled $38,000, $97,000 and $201,000, respectively,
for the years ended December 31, 1995, 1996 and 1997, and is included in cost of
data management services and licenses and implementation services in the
statements of operations.

                            SCC COMMUNICATIONS CORP.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
              (INCLUDING INFORMATION RELATED TO UNAUDITED PERIODS)
 
REVENUE RECOGNITION
 
     The Company's revenue is derived from 9-1-1 data management services and
certain license fees and related implementation services that the Company
provides to telephone companies. Revenue from data management services generally
consists of a non-recurring initial fee and monthly recurring revenue. The non-
recurring initial fee is recognized using the percentage-of-completion method
over the period required to convert the customer's data to the Company's system
and otherwise prepare for implementation. Revenue from recurring monthly
services is recognized in the period the services are rendered. Related expenses
are recognized as they are incurred and are included in cost of data management
services in the accompanying statements of operations.
 
     Because the Company's software requires significant modification for each
customer, revenue related to software license fees and implementation of the
Company's 9-1-1 systems at customer sites is recognized using the
percentage-of-completion method. Such contracts include a license fee for the
use of the Company's software and service fees for the installation and
customization of the system. The Company's costs to install its systems include
direct labor and expenses. Such costs are included in cost of licenses and
implementation services.
 
     In applying the percentage-of-completion method, revenue and related costs
are recognized based on the percentage that labor hours incurred to date bear to
total estimated labor hours. Revenue recognized in excess of amounts billed is
reflected as unbilled project revenue and amounts billed in excess of revenue
recognized are reflected as deferred contract revenue in the accompanying
balance sheets. The Company recognizes any known or anticipated loss on
contracts in process when such losses are determined to exist.
 
     Revenue from licenses and implementation services includes customer support
revenue which is recognized ratably over the related contract period on a
straight-line basis. Costs related to customer support revenue are included in
cost of licenses and implementation services in the accompanying statements of
operations.
 
CONCENTRATION OF CREDIT RISK
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk are primarily accounts receivable. The Company's
customers are generally telecommunications service providers; accordingly, the
Company's accounts receivable are concentrated in the telecommunications
industry. The Company's principal customers (Note 11) accounted for 86% and 40%
of the Company's accounts receivable as of December 31, 1996 and 1997,
respectively. The Company has no significant financial instruments with
off-balance sheet risk of accounting loss, such as foreign exchange contracts,
option contracts or other foreign currency hedging arrangements.
 
RESEARCH AND DEVELOPMENT
 
     Research and development efforts consist of salaries, supplies and other
related costs. These costs are expensed as incurred and totaled approximately
$388,000, $230,000 and $738,000 for the years ended December 31, 1995, 1996 and
1997, respectively. These costs are included in cost of data management services
and licenses and implementation services in the accompanying statements of
operations and do not include development costs incurred as part of the efforts
performed under licenses and implementation services contracts with the
Company's customers.
 
CASH AND CASH EQUIVALENTS
 
     For purposes of reporting cash flows, cash and cash equivalents include
highly liquid investments with original maturities of 90 days or less.

              (INCLUDING INFORMATION RELATED TO UNAUDITED PERIODS)
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions. These estimates affect the reported amounts of assets and
liabilities, disclosure of contingent assets and liabilities at the date of the
financial statements, and the reported amounts of revenue and expenses during
the reporting period. Actual results could differ from those estimates.

     Financial instruments include cash and cash equivalents, accounts
receivable and debt obligations. The carrying amounts for cash and cash
equivalents and accounts receivable approximate fair market value because of the
short maturity of these instruments. The fair value of notes and capital lease
obligations are estimated based on current rates available for similar debt with
maturities and securities, and at December 31, 1996 and 1997, approximates the
carrying value.
 
INCOME TAXES
 
     The Company follows Statement of Financial Accounting Standards No. 109
("SFAS 109"), which requires recognition of deferred income tax assets and
liabilities for the expected future income tax consequences, based on enacted
tax laws, of temporary differences between the financial reporting and tax bases
of assets and liabilities. SFAS 109 also requires recognition of deferred tax
assets for the expected future tax effects of loss carryforwards and tax credit
carryforwards. Deferred tax assets are then reduced, if deemed necessary, by a
valuation allowance for the amount of any tax benefits which, on a more likely
than not basis, are not expected to be realized (Note 7).
 
STOCK BASED COMPENSATION PLANS
 
     The Company applies APB Opinion No. 25, "Accounting for Stock Issued to
Employees," in accounting for its stock option and other stock-based
compensation plans for employees and directors. The Company has adopted the
disclosure provisions of Statement of Financial Accounting Standards No. 123
("SFAS 123"), "Accounting for Stock-Based Compensation," for such options and
stock-based plans for employees and directors (Note 5).
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
     The Company reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable from future undiscounted cash flows. Impairment losses are
recorded for the excess, if any, of the carrying value over the fair value of
the long-lived assets.
 
EARNINGS PER SHARE
 
     The Company has adopted Statement of Financial Accounting Standards No.
128, "Earnings Per Share," by retroactively restating loss per share amounts for
all periods presented. "Basic income (loss) per share" is determined by dividing
net income (loss) available to common shareholders by the weighted average
number of common shares outstanding during each period. "Diluted income (loss)
per share" includes the effects of potentially issuable common stock, but only
if dilutive (i.e., a loss per share is never reduced). The treasury stock
method, using the average price of the Company's common stock for the period, is
applied to determine dilution from options and warrants. The if-converted method
is used for convertible securities. Potentially dilutive common stock options
that were excluded from the calculation of diluted income per share

because their effect is antidilutive totaled 230,316 and 298,017 in 1996 and
1997, respectively, and 46,801 for the three months ended March 31, 1997.
Because of the reported net loss available to common shareholders in 1995,
4,920,954 shares of mandatorily redeemable convertible preferred stock
("Convertible Preferred Stock") and 497,078 common stock options were excluded
from the calculation of diluted net loss per share because their effect is
antidilutive.
 
     A reconciliation of the numerators and denominators used in computing per
share net income (loss) from continuing operations is as follows:

REVERSE STOCK SPLIT AND INCREASE IN AUTHORIZED SHARES
 
     On March 18, 1998, the Company's Board of Directors authorized a
one-for-three reverse stock split to be effective upon the effective date of a
Registration Statement on Form S-1 filed by the Company with the Securities and
Exchange Commission. All share amounts, equivalent share amounts and per share
amounts have been adjusted retroactively to reflect the reverse stock split. The
Company's Board of Directors also authorized an increase in authorized common
stock to 30,000,000 shares and authorized 15,000,000 shares of undesignated
preferred stock.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 130 ("SFAS 130"), "Reporting
Comprehensive Income." This statement, effective for fiscal years beginning
after December 15, 1997, would require the Company to report components of
comprehensive income in a financial statement that is displayed with the same
prominence as other financial statements. Comprehensive income is defined by
Concepts Statement No. 6, "Elements of Financial Statements," as the change in
equity of a business enterprise during a period from transactions and other
events and circumstances from nonowner sources. It includes all changes in
equity during a period except those resulting from investments by owners and
distributions to owners. The Company adopted SFAS 130 in the first quarter of
1998, however, the Company did not have any transactions which would require
additional disclosure under SFAS 130.
 
     Also in June 1997, the FASB issued Statement of Financial Accounting
Standards No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise and
Related Information." This statement, effective for financial statements for
periods beginning after December 15, 1997, requires that a public business
enterprise report financial and descriptive information about its reportable
operating segments. Generally, financial information is required to be reported
on the basis that it is used internally for evaluation of segment performance
and deciding how to allocate resources to segments. The adoption of SFAS 131 is
not expected to have a material impact on the Company's financial statements.

UNAUDITED PRO FORMA INFORMATION
 
   
     The Company is contemplating a public offering of its common stock. If such
an offering is consummated, all of the Convertible Preferred Stock (Note 4)
outstanding as of the closing date will be converted into shares of common
stock. In addition, the put option related to common stock warrants will expire
upon completion of the offering and the common stock warrants will be exercised
for $100 into shares of common stock. The pro forma stockholders' equity in the
balance sheet as of December 31, 1997 reflects the conversion of all outstanding
Convertible Preferred Stock and the exercise of the common stock warrant to
stockholders' equity (deficit). Had the conversion of the Convertible Preferred
Stock occurred on January 1, 1997, basic and diluted net income per share from
continuing operations would have been $0.59 and $0.54, respectively for the year
ended December 31, 1997.
    
 
INTERIM RESULTS (UNAUDITED)
 
     The accompanying balance sheet as of March 31, 1998, the statements of
operations and of cash flows for the three months ended March 31, 1997 and 1998,
and the statement of stockholders' equity (deficit) for the three months ended
March 31, 1998 are unaudited. In the opinion of management, the statements have
been prepared on the same basis as the audited financial statements and include
all adjustments, consisting only of normal recurring adjustments, necessary for
the fair statement of the results of the interim periods. Operating results for
the three months ended March 31, 1998 are not necessarily indicative of the
results that may be expected for the year ending December 31, 1998.
 
RECLASSIFICATIONS
 
     Certain reclassifications have been made to prior year balances to conform
to the current year presentation.
 
(3) DISCONTINUED OPERATIONS
 
     On June 30, 1997, the Company sold the net assets of its Premise Products
Division. The sale resulted in a net loss of $2,032,000. The net losses of this
division are included in the statements of operations as loss from operations of
discontinued division. Revenue from the division for the years ended December
31, 1995 and 1996 and the six months ended June 30, 1997, were $8,798,000,
$12,274,000 and $5,785,000, respectively.

     In March 1996, the Company authorized and issued 1,225,490 shares of Series
F Convertible Preferred Stock, with a liquidation or redemption price of
$5,000,000. The Company received cash proceeds of $3,956,000 and converted its
$1,000,000 note payable and accrued interest thereon of $44,000 to a stockholder
of the Company to Series F Convertible Preferred Stock in this offering.
 
     In the event of any liquidation, holders of Convertible Preferred Stock
would be entitled to preference in the amounts stated above. Any remaining
assets would be distributed to common and convertible preferred stockholders as
defined. At the request of the convertible preferred stockholders on any date
after March 1, 1998 (on March 18, 1998, the Convertible Preferred Stockholders
agreed to extend the date to September 1, 1998), the Convertible Preferred Stock
is redeemable at the above amounts. Such redemption, if requested, will be paid
in three installments as follows: first, the Company will redeem 50% of the
then-outstanding

Convertible Preferred Stock ten days subsequent to the redemption request (the
"Optional Redemption Date"); then 25% on the first anniversary of the Optional
Redemption Date; and finally, 25% on the second anniversary of the Optional
Redemption Date.
 
     Annual dividends of 8% accrue on Series A, B, C, D, E and F Convertible
Preferred Stock when and if declared by the Board of Directors. Upon redemption
or liquidation, a dividend of 8% per annum will accrue from the original
issuance date of the Series D, E and F Convertible Preferred Stock. Accordingly,
the Series D, E and F Convertible Preferred Stock in the accompanying balance
sheets include the accrual of such dividends through December 31, 1997. No
distributions may be made to common stockholders until declared and accrued
preferred stock dividends have been distributed. Common stock dividends may not
be made at a rate higher than the Convertible Preferred Stock dividends.
 
     Each share of Series A, B, C, D, E and F is convertible at the option of
the holder into one share of common stock. The conversion rate is subject to
adjustment if sales of common stock, or equivalent options, excluding sales to
employees under provisions of the stock option plan (see below), are made at a
price lower than the original issue price of the Convertible Preferred Stock.
Each share of Convertible Preferred Stock will be automatically converted into
common stock upon completion of a $10 million firmly underwritten public
offering at a minimum price of at least $6.00 per share or immediately upon
conversion of 75% of the Convertible Preferred Stock into common stock.
 
     During 1994, the Company issued notes payable to three of its existing
investors totaling $2,558,000. The notes were convertible into Series E at $3.00
per share and were interest bearing at 4% per annum. The investors received
warrants to purchase 200,000 shares of the Company's common stock for $600. The
warrants, exercisable for $.03 per share, were recorded at their estimated fair
market value of $100,000 and this amount was reflected as additional paid-in
capital. The notes payable were discounted by this amount and the discount was
being amortized as interest expense over the term of the debt. The notes were
due upon a public offering of the Company's common stock with a per share price
of at least $6.00 and aggregate proceeds of at least $10 million. Absent a
public offering prior to maturity, the notes were due or convertible into Series
E Convertible Preferred Stock, at the Company's option, on May 1, 1995. The
warrants had an expiration date of May 1, 1995. In January 1995, the debt and
accrued interest was replaced with new debt of $2,633,000 with similar terms,
convertible into 1,083,381 shares of Series E Convertible Preferred Stock (at
$2.43 per share). The warrants were canceled. The new debt was immediately
converted into 1,083,381 shares of Series E Convertible Preferred Stock, with a
liquidation or redemption price at that date of $2,633,000.
 
PUTABLE COMMON STOCK WARRANT
 
     In November 1997, the Company borrowed $4,000,000 from Banc One Capital
Partners II, LLC (the "Lender") (Note 6). In connection with the loan, the
Lender received a warrant to purchase 195,148 shares of the Company's common
stock for $100. Under the warrant, if the Company does not complete a qualified
public offering as defined in the related agreement within twelve months of the
date of the agreement, the number of shares under the warrant is increased by an
additional 97,574 shares of the Company's common stock. If the Company does not
complete a qualified public offering as defined in the related agreement within
eighteen months of the date of the agreement, the number of shares under the
warrant is increased by another 97,574 shares of the Company's common stock. The
Company recorded $1,464,000 for the estimated value of the shares exercisable
under the warrant as a discount on long-term note payable in the accompanying
balance sheets and is amortizing the discount into interest expense over the
six-year term of the note. The warrant expires on the date which is the earliest
of (i) the date on which a qualified initial public offering is completed, (ii)
the date on which a disposition or non-surviving combination is consummated,
(iii) the date on which the Lender exercises its rights under a co-sale
agreement to sell all of its warrant shares or (iv) 90 days after the maturity
date of the related note.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
              (INCLUDING INFORMATION RELATED TO UNAUDITED PERIODS)
 
     In addition, at any time after the occurrence of a put trigger event and
prior to a qualified public offering, as defined, the Lender may require the
Company to purchase all, but not less than all, of the common shares underlying
the warrant. A put trigger event is defined as the first to occur of any of the
following events: (1) the sixth anniversary date of the agreement; (2) a
disposition as defined in the agreement; (3) a non-surviving combination as
defined in the agreement; (4) the date upon which the Company prepays in full
the outstanding principal, interest and assessments, if any, on the note; or (5)
an acceleration event caused by a default of the note. The put price is
calculated as the greater of the market determined value amount as defined in
the agreement or an amount equal to six times earnings before interest, taxes,
depreciation and amortization for the preceding twelve months, reduced by
current outstanding indebtedness, increased by the fair market value of all
marketable securities, and divided by the number of fully diluted common shares
outstanding. On December 31, 1997, the Company recorded an amount equal to the
number of shares under the warrant times the difference between the current
market value, as defined, and the market value of the shares at the time the
warrant was issued. This amount of $8,000 was recorded as an increase in the
value of the putable common stock warrant and charged to accumulated deficit in
the accompanying financial statements.
 
     The Lender is entitled to request registration of such shares pursuant to a
registration rights agreement. In addition, if the Company proposes to register
any of its securities under the Securities Act, either for its own account or
for the account or for other security holders exercising registration rights,
the warrant holder is entitled to notice of such registration and is entitled to
include shares of such common stock therein.
 
     Pursuant to an agreement with the Lender, dated April 8, 1998, the warrant
will be exercised automatically just before or contemporaneously with the
effectiveness of a qualified initial public offering.
 
(5) STOCKHOLDERS' EQUITY (DEFICIT)
 
STOCK SUBSCRIPTIONS RECEIVABLE
 
     In September 1997, in connection with the sale of the Company's Premise
Products Division, several former employees of the Company signed full recourse
promissory notes to the Company to exercise their vested stock options. The
notes accrue interest at 6.07% per annum. The principal and accrued interest
thereon are due the earlier of September 28, 2000 or ninety days after the
Company becomes subject to the reporting requirements under Section 13 of the
Securities Exchange Act of 1934, as amended.
 
STOCK OPTION PLAN
 
     The Company's 1990 Stock Option Plan (the "1990 Option Plan"), as amended
by the Company's Board of Directors, provides officers and employees options to
purchase up to 2,262,205 shares of common stock of the Company. Under the terms
of the 1990 Option Plan, the Board of Directors may grant officers and employees
either nonqualified or incentive stock options, as defined by the Internal
Revenue Service. The purchase price of the shares subject to incentive stock
options will be the fair market value of the common stock on the date the option
is granted. Options granted under the 1990 Option Plan are exercisable up to ten
years from the date of the grant and are contingent upon continued employment
with the Company.
 
     In October 1995, the Company granted an option to purchase 66,666 shares of
common stock to an officer of the Company. The option is exercisable at $6.00
per share and was issuable contingent on the attainment of certain objectives.
During 1997, the Company's Board of Directors determined that the officer had
met the objectives required under the agreement, causing the options to be
issued. No compensation expense was recorded on this option because the exercise
price exceeded the fair market value of the shares.

STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123 ("SFAS 123")
 
     SFAS 123, "Accounting for Stock-Based Compensation," defines a fair value
based method of accounting for employee stock options or similar equity
instruments. However, SFAS 123 allows the continued measurement of compensation
cost for such plans using the intrinsic value based method prescribed by APB
Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25"), provided
that pro forma disclosures are made of net income or loss assuming the fair
value based method of SFAS 123 had been applied. The Company has elected to
account for its stock-based compensation plans under APB 25; accordingly, for
purposes of the pro forma disclosures presented below, the Company has computed
the fair values of all options granted under the 1990 Option Plan during 1995,
1996 and 1997, using the Black-Scholes pricing model and the following weighted
average assumptions:

Risk-free interest rate............................      5.85%        6.16%        6.41%
Expected dividend yield............................      0.00%        0.00%        0.00%
Expected lives outstanding.........................  5.0 years    5.0 years    5.0 years
Expected volatility................................     0.001%       0.001%       0.001%
</TABLE>
 
     To estimate lives of options for this valuation, it was assumed options
will be exercised upon becoming fully vested. All options are initially assumed
to vest. Cumulative compensation costs recognized in pro forma net income or
loss with respect to options that are forfeited prior to vesting is adjusted as
a reduction of pro forma compensation expense in the period of forfeiture.
Because the Company's common stock is not yet publicly traded, the expected
market volatility was assumed to be zero. Actual volatility of the Company's
common stock may vary. Fair value computations are highly sensitive to the
volatility factor assumed; the greater the volatility, the higher the computed
fair value of options granted.
 
     The total fair value of options granted under the 1990 Option Plan was
computed to be approximately $260,000, $187,000 and $499,000 for the years ended
December 31, 1995, 1996 and 1997, respectively. These amounts are amortized
ratably over the vesting periods of the options or recognized at date of grant
if no vesting period is required. Pro forma stock-based compensation, net of the
effect of forfeitures, was $26,000, $80,000 and $232,000 for 1995, 1996 and
1997, respectively.

1995, 1996 and 1997 and changes during the years then ended are presented below:

(7) INCOME TAXES
 
     The Company has operated in three countries, the United States, Canada and
Australia. For income tax return reporting purposes, the Company has
approximately $9,600,000 of net operating loss carryforwards; approximately
$364,000 of research and development tax credit carryforwards and $39,000 of
alternative minimum tax credit carryforwards available to offset future federal
taxable income or federal tax liabilities in the United States. The research and
development credit and net operating loss carryforwards expire at various dates
through 2011. The Company also has $208,000 of foreign tax credit carryforwards.
 
     The Tax Reform Act of 1986 contains provisions which may limit the net
operating loss and credit carryforwards available to be used in any given year
upon the occurrence of certain events including significant changes in ownership
of the Company. In accordance with certain provisions of the Internal Revenue
Code of 1986, as amended (the "Code"), a greater than 50% change in ownership of
a company within a three year period results in an annual limitation on the
Company's ability to utilize its net operating loss carryforwards from tax
periods prior to the ownership change.
 
     Deferred income tax assets and liabilities at December 31, 1996 and 1997,
were as follows:

     As of December 31, 1997, the Company reversed $2,500,000 of the valuation
allowance on part of its deferred tax assets, as the Company believes it is more
likely than not that such tax benefits will be realized.
    
 
   
     Management believes the entire tax benefit of $4,552,000 as of December 31,
1996 and the remaining tax benefit of $2,139,000 as of December 31, 1997, do not
satisfy the realization criteria set forth in SFAS No. 109 and has recorded a
valuation allowance for such net tax asset.

(9) EMPLOYEE BENEFIT PLAN
 
     The Company has a 401(k) plan under which eligible employees may defer up
to 15% of their compensation. The Company may make matching contributions and
discretionary contributions if approved by the Board of Directors. For 1995,
1996 and 1997, no employer matching or discretionary contributions were made to
the 401(k) plan.
 
(10) RELATED PARTY TRANSACTION
 
     The Company provides data management and certain consulting services to and
leases equipment from entities in which a stockholder of the Company has an
ownership interest. A representative of the stockholder is a member of the
Company's Board of Directors. The Company received net proceeds of approximately
$3,226,000, $6,606,000 and $6,959,000 in 1995, 1996 and 1997, respectively,
pursuant to these agreements. Amounts due to the stockholder under the lease
agreements net of amounts due to the Company for services rendered as of
December 31, 1996 and 1997 were $3,158,000 and $5,148,000, respectively. The
leases have interest rates ranging from 9.25% to 9.50%, require monthly payments
and have expiration dates varying through October 2002.
 
(11) MAJOR CUSTOMERS
 
     Revenue from certain customers exceeded 10% of total revenue for the
respective year as follows: 44%, 20% and 24% in 1995; 47% and 35% in 1996; and
30%, 29% and 22% in 1997. Contracts with certain of these customers have a
ten-year duration and provide for fixed monthly fees based upon the number of
subscriber records managed and upon the services selected by the customer.
 
(12) LEGAL MATTERS
 
     The Company is subject to various claims and business disputes in the
ordinary course of business. While the outcome of these matters cannot be
predicted with certainty, management anticipates that the ultimate outcome of
the issues will not have a material impact on the financial statements.
 
(13) SUBSEQUENT EVENTS (UNAUDITED)
 
     On March 18, 1998, the Company's Board of Directors authorized the filing
of a Registration Statement with the Securities and Exchange Commission covering
the proposed sale of shares of its common stock to the public.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
              (INCLUDING INFORMATION RELATED TO UNAUDITED PERIODS)
 
     On March 18, 1998, the Company adopted an employee stock purchase plan
("ESPP") under which eligible employees may contribute up to 10% of their
salaries through payroll deductions to purchase shares of the Company's common
stock. The first offering period of the ESPP began March 1, 1998 and will end
December 31, 1998. Thereafter, offering periods will be successive six month
periods. At the end of each offering period, amounts contributed by employees
will be used to purchase shares of the Company's common stock at a price equal
to 85% of the lower of the closing price of the common stock on the first day or
last day of the offering period. The Company's Board of Directors has authorized
the issuance of up to 200,000 shares under the ESPP and may terminate the ESPP
at any time. At January 1 of each year, the shares available under the ESPP will
be restored to 200,000, although the Company's Board of Directors may elect to
restore a lesser number of shares.
 
     On April 7, 1998, the Company adopted the 1998 Stock Incentive Plan ("1998
Plan"), which is a successor to the 1990 Option Plan, to become effective upon a
qualified initial public offering. A total of 1,901,055 shares have been
authorized for issuance under the 1998 Plan, including shares authorized under
the 1990 Option Plan. The shares reserved for issuance will increase
automatically on the first trading day of each calendar year, beginning with the
1999 calendar year, by 3% of the number of shares of common stock outstanding on
the last trading day of the immediately preceding calendar year. The 1998 Plan
allows for issuances of options to officers, non-employee Board members and
consultants, as provided for under the terms of the 1998 Plan.

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
     Section 145 of the Delaware General Corporation Law permits indemnification
of officers and directors of the Company under certain conditions and subject to
certain limitations. Section 145 of the Delaware General Corporation Law also
provides that a corporation has the power to purchase and maintain insurance on
behalf of its officers and directors against any liability asserted against such
person and incurred by him or her in such capacity, or arising out of his or her
status as such, whether or not the corporation would have the power to indemnify
him or her against such liability under the provisions of Section 145 of the
Delaware General Corporation Law.
 
     Effective as of the closing of this offering, Article VII, Section 1 of the
Restated Bylaws of the Company will provide that the Company shall indemnify its
Directors and executive officers to the fullest extent not prohibited by the
Delaware General Corporation Law. The rights to indemnity thereunder will
continue as to a person who has ceased to be a Director, officer, employee or
agent and inure to the benefit of the heirs, executors and administrators of the
person. In addition, expenses incurred by a Director or executive officer in
defending any civil, criminal, administrative or investigative action, suit or
proceeding by reason of the fact that he or she is or was a Director or officer
of the Company (or was serving at the Company's request as a Director or officer
of another corporation) will be paid by the Company in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking by
or on behalf of such Director or officer to repay such amount if it shall
ultimately be determined that he or she is not entitled to be indemnified by the
Company as authorized by the relevant section of the Delaware General
Corporation Law.
 
     As permitted by Section 102(b)(7) of the Delaware General Corporation Law,
effective as of the closing of this offering, Article V, Section (A) of the
Company's Amended and Restated Certificate of Incorporation will provide that a
Director of the Company shall not be personally liable for monetary damages for
breach of fiduciary duty as a Director, except for 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 acts or omissions that involve
intentional misconduct or a knowing violation of law, (iii) under Section 174 of
the Delaware General Corporation Law or (iv) for any transaction from which the
Director derived any improper personal benefit.
 
     The Company intends to enter into indemnification agreements with each of
its Directors and executive officers, effective upon the effectiveness of this
Registration Statement. Generally, the indemnification agreements will attempt
to provide the maximum protection permitted by Delaware law as it may be amended
from time to time. Moreover, the indemnification agreements will provide for
certain additional indemnification. Under such additional indemnification
provisions, however, an individual will not receive indemnification
 
                                      II-1
<PAGE>   88
 
for judgments, settlements or expenses if he or she is found liable to the
Company (except to the extent the court determines he or she is fairly and
reasonably entitled to indemnity for expenses), for settlements not approved by
the Company, or for settlements and expenses if the settlement is not approved
by the court. The indemnification agreements will provide for the Company to
advance to the individual any and all reasonable expenses (including legal fees
and expenses) incurred in investigating or defending any such action, suit or
proceeding. In order to receive an advance of expenses, the individual must
submit to the Company copies of invoices presented to him or her for such
expenses. Also, the individual must repay such advances upon a final judicial
decision that he or she is not entitled to indemnification.
 
     The Company has purchased directors' and officers' liability insurance.
 
     The Underwriting Agreement (Exhibit 1.1 hereto) contains provisions by
which the Underwriters have agreed to indemnify the Company, each person, if
any, who controls the Company within the meaning of Section 15 of the Securities
Act, each Director of the Company, and each officer of the Company who signs
this Registration Statement, with respect to information furnished in writing by
or on behalf of the Underwriters for use in this Registration Statement.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
     Since March 31, 1995, the Company has sold and issued the following
unregistered securities.
 
          (1) From March 31, 1995 to May 18, 1998, the Company issued an
     aggregate of 749,078 options to purchase Common Stock with exercise prices
     ranging from $0.30 to $12.75 per share under the 1990 Option Plan and an
     aggregate of 235,912 shares of Common Stock were issued through the
     exercise of options granted under the 1990 Option Plan for an aggregate
     exercise price of $159,908. For additional information concerning these
     transactions, reference is made to the information contained under the
     caption "Management -- Benefit Plans" in the form of the Prospectus
     included herein.
 
          (2) On March 5, 1996, the Company issued an aggregate of 1,225,490
     shares of Series F Preferred Stock to three investors for an aggregate
     consideration of $5,000,000.
 
          (3) On November 20, 1997, the Company issued a warrant to purchase
     that number of Common Shares of the Company representing between two
     percent and four percent of the fully diluted Common Stock of the Company,
     depending upon certain circumstances, to Banc One Capital Partners II, LLC
     in connection with a loan agreement.
 
     The sales and issuances of securities in the above transactions were deemed
to be exempt under the Act by virtue of Section 4(2) thereof and/or Regulation D
and Rule 701 promulgated thereunder as transactions not involving any public
offering. The purchasers in each case represented their intention to acquire the
securities for investment only and not with a view to the distribution thereof.
Appropriate legends were affixed to the stock certificates issued in such
transactions. Similar representations of investment intent were obtained and
similar legends imposed in connection with any subsequent transfers of any such
securities. The Company believes that all recipients had adequate access,
through employment or other relationships, to information about the Company to
make an informed investment decision.

ITEM 17. UNDERTAKINGS.
 
     The undersigned 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.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to Directors, officers and controlling persons of the Company
pursuant to the provisions described in Item 14, or otherwise, the Company 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 Company of expenses
incurred or paid by a Director, officer or controlling person of the Company 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 Company 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 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 part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, 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.

                            SCC COMMUNICATIONS CORP.
                          EMPLOYEE STOCK PURCHASE PLAN


                               ARTICLE I - PURPOSE

         I.1. PURPOSE. The SCC Communications Corp. Employee Stock Purchase Plan
is intended to provide a method whereby employees of SCC Communications Corp.
and its subsidiary corporations (hereinafter referred to, unless the context
otherwise requires, as the "Company") will have an opportunity to acquire a
proprietary interest in the Company through the purchase of shares of the Common
Stock of the Company. It is the intention of the Company to have the Plan
qualify as an "employee stock purchase plan" under Section 423 of the Internal
Revenue Code of 1986, as amended (the "Code"). The provisions of the Plan shall
be construed so as to extend and limit participation in a manner consistent with
the requirements of that section of the Code.


                            ARTICLE II - DEFINITIONS

         II.1. BASE PAY. "Base Pay" shall mean regular straight-time earnings,
including shift premiums, but excluding payments for overtime, bonuses and other
special payments, commissions and other marketing incentive payments.

         II.2. COMMITTEE. "Committee" shall mean the individuals described in
Article XI.

         II.3. EMPLOYEE. "Employee" means any person who is customarily employed
on a regular full-time or part-time basis by the Company and is regularly
scheduled to work more than 20 hours per week.

         II.4. SUBSIDIARY CORPORATION. "Subsidiary Corporation" shall mean any
present or future corporation which (i) would be a "subsidiary corporation" of
SCC Communications Corporation as that term is defined in Section 424 of the
Code and (ii) is designated as a participant in the Plan by the Committee.


                   ARTICLE III - ELIGIBILITY AND PARTICIPATION

         III.1. INITIAL ELIGIBILITY. Any employee who is employed by the Company
on the Offering Commencement Date (as defined below) shall be eligible to
participate in such Offering.

         III.2. LEAVE OF ABSENCE. For purposes of participation in the Plan, a
person on leave of absence shall be deemed to be an employee for the first 90
days of such leave of absence and such employee's employment shall be deemed to
have terminated (for purposes of this Plan only) at the close of business on the
90th day of such leave of absence unless such employee shall have returned to
regular full-time or part-time employment (as the case may be) prior to

<PAGE>   2


the close of business on such 90th day. Termination by the Company of any
employee's leave of absence, other than termination of such leave of absence on
return to full-time or part-time employment, shall terminate an employee's
employment for all purposes of the Plan and shall terminate such employee's
participation in the Plan and right to exercise any option.

         III.3. RESTRICTIONS ON PARTICIPATION. Notwithstanding any provisions of
the Plan to the contrary, no employee shall be granted an option to participate
in the Plan:

                  (a) If, immediately after the grant, such employee would own
stock, and/or hold outstanding options to purchase stock, possessing 5% or more
of the total combined voting power or value of all classes of stock of the
Company (for purposes of this paragraph, the rules of ss. 424(d) of the Code
shall apply in determining stock ownership of any employee); or

                  (b) Which permits his rights to purchase stock under all
employee stock purchase plans of the Company to accrue at a rate which exceeds
$25,000 in fair market value of the Common Stock (determined at the time such
option is granted) for each calendar year in which such option is outstanding.

         III.4. COMMENCEMENT OF PARTICIPATION. An eligible employee may become a
participant by completing an authorization for a payroll deduction on the form
provided by the Company and filing it with the office of the Treasurer of the
Company on or before the date set therefor by the Committee, which date shall be
prior to the Offering Commencement Date for the Offering (as such terms are
defined below). Payroll deductions for a participant shall commence on the
applicable Offering Commencement Date when his authorization for a payroll
deduction becomes effective and shall end on the Offering Termination Date of
the Offering to which such authorization is applicable unless sooner terminated
by the participant as provided in Article VIII.


                             ARTICLE IV - OFFERINGS

         IV.1. ANNUAL OFFERINGS. The Plan will be implemented by semiannual
offerings of the Company's Common Stock (the "Offerings") beginning on the 1st
day of January and the 1st day of July in each year, and terminating on June 30
and December 31 of the same year, respectively. Notwithstanding the above, the
first Offering shall begin on March 1, 1998 and terminate on December 31, 1998,
with no Offering beginning on June 1, 1998.

         As used in the Plan, "Offering Commencement Date" means the March 1,
1998, or the January 1 or July 1 date, as the case may be, on which the
particular Offering begins and "Offering Termination Date" means the June 30 or
December 31 date, as the case may be, on which the particular Offering
terminates. If an Offering period begins or terminates on a Saturday, Sunday or
legal holiday, then the first or last day of the Offering, as applicable, shall


                                      -2-
<PAGE>   3


be the first business day after that date (for Offering period commencements) or
the last business day prior to that date (for Offering period terminations).

                         ARTICLE V - PAYROLL DEDUCTIONS

         V.1. AMOUNT OF DEDUCTION. At the time a participant files his
authorization for payroll deduction, he shall elect to have deductions made from
his pay on each payday during the time he is a participant in an Offering at the
rate of 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10% of his base pay in effect at the
Offering Commencement Date of such Offering. In the case of a part-time hourly
employee, such employee's Base Pay during an Offering shall be determined by
multiplying such employee's hourly rate of pay in effect on the Offering
Commencement Date by the number of regularly scheduled hours of work for such
employee during such Offering.

         V.2. PARTICIPANT'S ACCOUNT. All payroll deductions made for a
participant shall be credited to his account under the Plan. A participant may
not make any separate cash payment into such account except for the period of
March 1, 1998 until the next payday or when on leave of absence (and then only
as provided in Section 5.4, below).

         V.3. CHANGES IN PAYROLL DEDUCTIONS. A participant may discontinue his
participation in the Plan as provided in Article VIII, but no other change can
be made during an Offering, except that a participant may decrease the amount of
his payroll deductions for that Offering one (1) time during any Offering.

         V.4. LEAVE OF ABSENCE. If a participant goes on a leave of absence,
such participant shall have the right to elect: (a) to withdraw the balance in
his account pursuant to Section 7.2, (b) to discontinue contributions to the
Plan but remain a participant in the Plan, or remain a participant in the Plan
during such leave of absence, authorizing deductions to be made from payments by
the Company to the participant during such leave of absence and undertaking to
make cash payments to the Plan at the end of each payroll period to the extent
that amounts payable by the Company to such participant are insufficient to meet
such participant's authorized Plan deductions.

<PAGE>   4

                         ARTICLE VI - GRANTING OF OPTION

         VI.1. NUMBER OF OPTION SHARES. On each Offering Commencement Date, a
participating employee shall be deemed to have been granted an option to
purchase a maximum number of shares of the Common Stock of the Company equal to
an amount determined as follows: an amount equal to (i) that percentage of the
employee's Base Pay which he has elected to have withheld (but not in any case
in excess of 10%) multiplied by (ii) the employee's Base Pay on the Offering
Commencement Date divided by (iii) 85% of the market value of the Common Stock
of the Company on the Offering Commencement Date or Offering Termination Date
(as determined pursuant to Section 6.2, below). The market value of the
Company's stock shall be determined as provided in paragraphs (a) and (b) of
Section 6.2 below. An employee's Base Pay during the period of an offering shall
be determined by multiplying his normal monthly rate of pay (as in effect on the
Offering Commencement Date) by 6, or the hourly rate by 1040, as the case may
be, provided that, in the case of a part time hourly employee, the employee's
Base Pay during the period of an Offering shall be determined by multiplying
such employee's hourly rate by the number of regularly scheduled hours of work
for such employee during such Offering. An employee's Base Pay during the
Offering with the Offering Commencement Date of March 1, 1998 shall be
determined by multiplying his normal monthly rate of pay (as determined on the
Offering Commencement Date) by 10, or the hourly rate by 1760.

         VI.2. OPTION PRICE. The option price of Common Stock purchased with
payroll deductions made during an Offering for a participant therein shall be
the lower of:

                  (a) 85% of the closing price of the Common Stock on the
Offering Commencement Date or the nearest prior business day on which trading
occurred on the NASDAQ National Market System; or

                  (b) 85% of the closing price of the Common Stock on the
Offering Termination Date or the nearest prior business day on which trading
occurred on the NASDAQ National Market System. If the Common Stock of the
Company is not admitted to trading on any of the aforesaid dates for which
closing prices of the Common Stock are to be determined, then reference shall be
made to the fair market value of the Common Stock on that date, as determined on
such basis as shall be established or specified for the purpose by the
Committee.

                        ARTICLE VII - EXERCISE OF OPTION

         VII.1. AUTOMATIC EXERCISE. Unless a participant gives written notice to
the Company as hereinafter provided, his option for the purchase of Common Stock
with payroll deductions made during any Offering will be deemed to have been
exercised automatically on the Offering Termination Date applicable to such
Offering, for the purchase of the number of full shares of Common Stock which
the accumulated payroll deductions in his account at that time will purchase at
the applicable option price (but not in excess of the number of shares for which
options have been granted to the employee pursuant to Section 6.1), and any
excess in his account at that time will be returned to him.

         VII.2. WITHDRAWAL OF ACCOUNT. By written notice to the Plan
Administrator, at any time prior to the Offering Termination Date applicable to
any Offering, a participant may elect to withdraw all the accumulated payroll
deductions in his account at such time.

         VII.3. FRACTIONAL SHARES. Fractional shares will not be issued under
the Plan and any accumulated payroll deductions which would have been used to
purchase fractional shares will be returned to any employee promptly following
the termination of an Offering, without interest.

         VII.4. TRANSFERABILITY OF OPTION. During a participant's lifetime,
options held by such participant shall be exercisable only by that participant.

         VII.5. DELIVERY OF STOCK. As promptly as practicable after the Offering
Termination Date of each Offering, the Company will deliver to each participant,
as appropriate, a certificate representing the shares of Common Stock purchased
upon exercise of his option.


                            ARTICLE VIII - WITHDRAWAL

         VIII.1. IN GENERAL. As indicated in Section 7.2, a participant may
withdraw payroll deductions credited to his account under the Plan at any time
by giving written notice to the Plan Administrator. All of the participant's
payroll deductions credited to his account will be paid to him promptly after
receipt of his notice of withdrawal, and no further payroll deductions will be
made from his pay during such Offering. The Company may, at its option, treat
any attempt to borrow by an employee on the security of his accumulated payroll
deductions as an election, under Section 3.2, to withdraw such deductions.

         VIII.2. EFFECT ON SUBSEQUENT PARTICIPATION. A participant's withdrawal
from any Offering will not have any effect upon his eligibility to participate
in any succeeding Offering or in any similar plan which may hereafter be adopted
by the Company.


                                      -5-
<PAGE>   6

         VIII.3. TERMINATION OF EMPLOYMENT. Upon termination of the
participant's employment for any reason (but excluding retirement or death while
in the employ of the Company or during continuation of a leave of absence for a
period beyond 90 days), the payroll deductions credited to his account will be
returned to him, or, in the case of his death subsequent to the termination of
his employment, to the person or persons entitled thereto under Section 12.1.

         VIII.4. TERMINATION OF EMPLOYMENT DUE TO DEATH. Upon termination of the
partici pant's employment because of his death, his beneficiary (as defined in
Section 12.1) shall have the right to elect, by written notice given to the Plan
Administrator prior to the earlier of the Offering Termination Date or the
expiration of a period of sixty (60) days commencing with the date of the death
of the participant, either:

                  (a) To withdraw all of the payroll deductions credited to the
participant's account under the Plan, or

                  (b) To exercise the participant's option for the purchase of
stock on the Offering Termination Date next following the date of the
participant's death for the purchase of the number of full shares of stock which
the accumulated payroll deductions in the participant's account at the date of
the participant's death will purchase at the applicable option price, and any
excess in such account will be returned to said beneficiary, without interest.

         In the event that no such written notice of election shall be duly
received by the Plan Administrator, the beneficiary shall automatically be
deemed to have elected, pursuant to paragraph (b), to exercise the participant's
option.

         VIII.5. TERMINATION OF EMPLOYMENT DUE TO RETIREMENT. Upon termination
of the participant's employment because of his retirement, the participant shall
have the right to elect, by written notice given to the Plan Administrator prior
to the earlier of the Offering Termination Date or the expiration of a period of
sixty (60) days commencing with the date of the retirement of the participant,
either:

                  (a) To withdraw all of the payroll deductions credited to the
participant's account under the Plan, or

                  (b) To exercise the participant's option for the purchase of
stock on the Offering Termination Date next following the date of the
participant's retirement for the purchase of the number of full shares of stock
which the accumulated payroll deductions in the participant's account at the
date of the participant's retirement will purchase at the applicable option
price, and any excess in such account will be returned to the participant,
without interest.

In the event that no such written notice of election shall be duly received by
the Plan


                                      -6-

<PAGE>   7


Administrator, the participant shall automatically be deemed to have elected to
withdraw all payroll deductions pursuant to paragraph (a), above.

         VIII.6. LEAVE OF ABSENCE. A participant on leave of absence shall,
subject to the election made by such participant pursuant to Section 5.4,
continue to be a participant in the Plan so long as such participant is on
continuous leave of absence. A participant who has been on leave of absence for
more than 90 days and who therefore is not an employee for the purpose of the
Plan shall not be entitled to participate in any offering commencing after the
90th day of such leave of absence. Notwithstanding any other provisions of the
Plan, unless a participant on leave of absence returns to regular full time or
part time employment with the Company at the earlier of: (a) the termination of
such leave of absence, or (b) three months from the 90th day of such leave of
absence, such participant's participation in the Plan shall terminate on
whichever of such dates first occurs.


                              ARTICLE IX - INTEREST

         IX.1. NO PAYMENT OF INTEREST. No interest will be paid or allowed on
any money paid into the Plan or credited to the account of any participant
employee.


                                ARTICLE X - STOCK

         X.1. MAXIMUM SHARES. The maximum number of shares which shall be issued
under the Plan, subject to adjustment upon changes in capitalization of the
Company as provided in Section 12.4 shall be 200,000 shares, plus an annual
increase to be added on each anniversary date of the adoption of the Plan equal
to the lesser of (i) the number of shares needed to restore the maximum
aggregate number of shares available for sale under the Plan to 200,000, or (ii)
a lesser amount determined by the Board. If the total number of shares for which
options are exercised in any Offering Termination Date in accordance with
Article VI exceeds the maximum number of shares for the Plan, the Company shall
make a pro rata allocation of the shares available for delivery and distribution
in as nearly a uniform manner as shall be practicable and as it shall determine
to be equitable, and the balance of payroll deductions credited to the account
of each participant under the Plan shall be returned to him as promptly as
possible.

         X.2. PARTICIPANT'S INTEREST IN OPTION STOCK. The participant will have
no interest in the shares of Common Stock covered by his option until such
option has been exercised.

         X.3. REGISTRATION OF STOCK. Stock to be delivered to a participant
under the Plan will be registered in the name of the participant, or, if the
participant so directs by written notice to the Plan Administrator prior to the
Offering Termination Date applicable thereto, in the names of the participant
and one such other person as may be designated by the participant, as joint


                                      -7-

<PAGE>   8

tenants with rights of survivorship or as tenants by the entireties, to the
extent permitted by applicable law.

         X.4. RESTRICTIONS ON EXERCISE. The Board of Directors may, in its
discretion, require as conditions to the exercise of any option that the shares
of Common Stock reserved for issuance upon the exercise of the option shall have
been duly listed, upon official notice of issuance, upon a stock exchange, and
that either:

                  (a) A Registration Statement under the Securities Act of 1933,
as amended, with respect to said shares shall be effective, or

                  (b) The participant shall have represented at the time of
purchase, in form and substance satisfactory to the Company, that it is his
intention to purchase the shares for investment and not for resale or
distribution.


                           ARTICLE XI - ADMINISTRATION

         XI.1. APPOINTMENT OF COMMITTEE. The Board of Directors shall appoint a
committee (the "Committee") to administer the Plan, which shall consist of no
fewer than two members of the Board of Directors, none of whom are employees of
the Company. No member of the Committee shall be eligible to purchase shares of
Common Stock under the Plan. Each member of the Committee shall be a
"disinterested person" as that term is defined in Rule 16b-3 of the Securities
Exchange Act of 1934, as such rule may be amended from time to time.

         XI.2. AUTHORITY OF COMMITTEE. Subject to the express provisions of the
Plan, the Committee shall have plenary authority in its discretion to interpret
and construe any and all provisions of the Plan, to adopt rules and regulations
for administering the Plan, and to make all other determinations deemed
necessary or advisable for administering the Plan. The Committee's determination
on the foregoing matters shall be conclusive.

         XI.3. RULES GOVERNING THE ADMINISTRATION OF THE COMMITTEE. The Board of
Directors may from time to time appoint members of the Committee in substitution
for or in addition to members previously appointed and may fill vacancies,
however caused, in the Committee. The Committee may select one of its members as
its Chairman and shall hold its meetings at such times and places as it shall
deem advisable and may hold telephonic meetings. A majority of its members shall
constitute a quorum. All determinations of the Committee shall be made by a
majority of its members. The Committee may correct any defect or omission or
reconcile any inconsistency in the Plan, in the manner and to the extent it
shall deem desirable. Any decision or determination reduced to writing and
signed by a majority of the members of the Committee shall be as fully effective
as if it had been made by a majority vote at a meeting duly called and held. The
Committee may appoint a secretary and shall make such rules and regulations for
the conduct of its business as it shall deem advisable.


                                      -8-

<PAGE>   9

         XI.4. ADMINISTRATION OF PLAN. The day to day functions of the Plan
shall be administered by a Plan Administrator who shall be appointed by the
Committee. All notices and authorizations under the Plan shall be directed to
the attention of the Plan Administrator.


                           ARTICLE XII - MISCELLANEOUS

         XII.1. DESIGNATION OF BENEFICIARY. A participant may file a written
designation of a beneficiary who is to receive any shares of Common Stock and/or
cash distributed under the Plan. Such designation of beneficiary may be changed
by the participant at any time by written notice to the Plan Administrator. Upon
the death of a participant and upon receipt by the Company of proof of identity
and existence at the participant's death of a beneficiary validly designated by
him under the Plan, the Company shall deliver such shares of Common Stock and/or
cash to such beneficiary. In the event of the death of a participant and in the
absence of a beneficiary validly designated under the Plan who is living at the
time of such participant's death, the company shall deliver such stock and/or
cash to the executor or administrator of the estate of the participant, or if no
such executor or administrator has been appointed (to the knowledge of the
Company), the Company, in its discretion, may deliver such stock and/or cash to
the spouse or to any one or more dependents of the participant as the Company
may designate. No beneficiary shall, prior to the death of the participant by
whom he has been designated, acquire any interest in the shares of Common Stock
or cash credited to the participant under the Plan.

         XII.2. TRANSFERABILITY. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive stock under the Plan may be assigned, transferred, pledged, or
otherwise disposed of in any way by the participant other than by will or the
laws of descent and distribution. Any such attempted assignment, transfer,
pledge or other disposition shall be without effect, except that the Company may
treat such act as an election to withdraw funds in accordance with Section 7.2.

         XII.3. USE OF FUNDS. All payroll deductions received or held by the
Company under this Plan may be used by the Company for any corporate purpose and
the Company shall not be obligated to segregate such payroll deductions.

         XII.4.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.

                  (a) If, while any options are outstanding, the outstanding
shares of Common Stock of the Company have increased, decreased, changed into,
or been exchanged for a different number or kind of shares or securities of the
Company through reorganization, recapitalization, reclassification, stock split,
reverse stock split or similar transaction, appropriate and proportionate
adjustments may be made by the Committee in the number and/or kind of shares
which are subject to purchase under outstanding options and on the


                                      -9-

<PAGE>   10

option exercise price or prices applicable to such outstanding options. In
addition, in any such event, the number and/or kind of shares which may be
offered in the Offerings described in Article IV hereof shall also be
proportionately adjusted. No adjustments shall be made for stock dividends. For
the purposes of this paragraph, any distribution of shares to shareholders in an
amount aggregating 20% or more of the outstanding shares shall be deemed a stock
split and any distributions of shares aggregating less than 20% of the
outstanding shares shall be deemed a stock dividend.

                  (b) Upon the dissolution or liquidation of the Company, or
upon a reorganization, merger or consolidation of the Company with one or more
corporations as a result of which the Company is not the surviving corporation,
or upon a reorganization, merger or consolidation of the Company with one or
more corporations as a result of which the holders of the Corporation's capital
stock prior to such transaction hold less than 50% of the capital stock of the
entity surviving such transaction, or upon a sale of all or substantially all of
the property or stock of the Company to another corporation, the holder of each
option then outstanding (and for which payroll deductions have been made) under
the Plan will thereafter be entitled to receive at the next Offering Termination
Date upon the exercise of such option for each share as to which such option
shall be exercised, as nearly as reasonably may be determined, the cash,
securities and/or property which a holder of one share of the Common Stock was
entitled to receive upon and at the time of such transaction. The Board of
Directors shall take such steps in connection with such transactions as the
Board shall deem necessary to assure that the provisions of this Section 12.4
shall thereafter be applicable, as nearly as reasonably may be determined, in
relation to the said cash, securities and/or property as to which such holder of
such option might thereafter be entitled to receive.

         XII.5. AMENDMENT AND TERMINATION. The Board of Directors shall have
complete power and authority to terminate or amend the Plan; provided, however,
that the Board of Directors shall not, without the approval of the shareholders
of the Corporation (i) increase the maximum number of shares which may be issued
under any Offering (except pursuant to Section 12.4); (ii) amend the
requirements as to the class of employees eligible to purchase stock under the
Plan or (iii) permit the members of the Committee to purchase stock under the
Plan. No termination, modification, or amendment of the Plan may, without the
consent of an employee then having an option under the Plan to purchase stock,
adversely affect the rights of such employee under such option; provided that
the Plan may be terminated at any time by the Company's Board of Directors. Upon
any termination of the Plan, all payroll deductions not used to purchase shares
of Common Stock shall be refunded.

         XII.6. EFFECTIVE DATE. The Plan shall become effective as of March 1,
1998, subject to approval by the holders of the majority of the Common Stock
present and represented at a special or annual meeting of the shareholders or by
consent held or executed on or before December 31, 1998. If the Plan is not so
approved, the Plan shall not become effective.

         XII.7. NO EMPLOYMENT RIGHTS. The Plan does not, directly or indirectly,
create any




                                      -10-


<PAGE>   11

right for the benefit of any employee or class of employees to purchase any
shares under the Plan, or create in any employee or class of employees any right
with respect to continuation of employment by the Company, and it shall not be
deemed to interfere in any way with the Company's right to terminate, or
otherwise modify, an employee's employment at any time.

         XII.8. EFFECT OF PLAN. The provisions of the Plan shall, in accordance
with its terms, be binding upon, and inure to the benefit of, all successors of
each employee participating in the Plan, including, without limitation, such
employee's estate and the executors, administrators or trustees thereof, heirs
and legatees, and any receiver, trustee in bankruptcy or representative of
creditors of such employee.

         XII.9. GOVERNING LAW. The law of the State of Colorado will govern all
matters relating to this Plan except to the extent it is superseded by the laws
of the United States.






As approved by the shareholders on April 1, 1998

kept, reproduced, and distributed by Ameritech so that Ameritech can
subsequently train its own personnel, provided that any reproductions of such
materials shall include any copyright or similar proprietary notices contained
in the materials.

Party's organization for a period of time to be mutually determined.  During
such time, the Intern shall participate in the organization's positioning,
structure, systems, management practices, culture, mission and strategy.  Each
Party shall be responsible for its own costs associated with this program.

                   11.    CONFIDENTIALITY AND NONDISCLOSURE

11.1.    NONDISCLOSURE AND SYSTEM SECURITY

SCC and Ameritech acknowledge the importance of maintaining the security and
integrity of the Network and the Ameritech Network (together, the "Networks")
and data of each Party as a result of their access to them.  In order to
protect the data and Networks, each Party shall strictly adhere to the
nondisclosure and System security policies in the performance of its own tasks
and the services related to this Agreement.  SCC understands and acknowledges
the confidential nature of Ameritech's telephone subscriber information:  it
shall not disclose data to which it has access under this Agreement to any
person or entity without the prior written consent of Ameritech, and shall
require each SCC employee to acknowledge in writing the confidential nature of
the data and agree to abide by the terms and conditions of this Section 11.

11.2.    CONFIDENTIAL INFORMATION

During the course of this Agreement, either Party may receive or have access to
confidential information of the other.  "Confidential Information" means any
information or data disclosed by a Party (the "Disclosing Party") to the other
Party (the "Recipient") under or in contemplation of this Agreement which (i)
if in tangible form or other media that can be converted to readable form is
clearly marked as proprietary, confidential or private when disclosed, or (b)
if oral or visual, is identified as proprietary, confidential or private on
disclosure.

The terms "Disclosing Party" and "Recipient" include each Party's corporate
affiliates that disclose or receive Confidential Information.  The rights and
obligations of the Parties shall therefore also inure to such affiliates and
may be directly enforced by or against such affiliates.

The Recipient acknowledges the economic value of the Disclosing Party's
Confidential Information.  The Recipient shall:

         (i)  use the Confidential Information only in connection with the
Recipient's performance of its obligations or exercise of its rights under this
Agreement;

         (ii)  restrict disclosure of the Confidential Information to employees
of the Recipient and its affiliates with a "need to know" and not disclose it
to any other person or entity without the prior written consent of the
Disclosing Party;

         (iii)  advise those employees who access the Confidential Information
of their obligations with respect thereto; and

         (iv)  copy the Confidential Information only as necessary for those
employees who are entitled to receive it, and ensure that all confidentiality
notices are reproduced in full on such copies.

For the purposes of this Agreement only, "employees" includes third parties
retained by the Parties for temporary administrative or clerical or programming
support.  A "need to know" means that the employee requires the Confidential
Information to perform his or her responsibilities in connection with this
Agreement.

The obligations of this Section shall not apply to any Confidential Information
which the Recipient can demonstrate:

         (i)     is or becomes available to the public through no breach of
this or any other agreements;

         (ii)    was previously known by the Recipient without any obligation
to hold it in confidence;

         (iii)   is received from a third party free to disclose such
information without restriction;

         (iv)    is independently developed by the Recipient without the use of
Confidential Information of the Disclosing Party;

         (v)     is approved for release by written authorization of the
Disclosing Party, but only to the extent of such authorization and without any
disassembly, reverse engineering, or similar undertaking by Recipient;

- --------------------------------------------------------------------------------




         (vi)    is required by law or regulation to be disclosed, but only to
the extent and for the purposes of such required disclosure, and only if the
Recipient first notifies the Disclosing Party of the order and permits the
Disclosing Party to seek an appropriate protective order; or

         (vii)   is disclosed in response to a valid order of a court or other
governmental body of the United States or any political subdivisions thereof,
but only to the extent of and for the purposes of such order, and only if the
Recipient first notifies the Disclosing Party of the order and permits the
Disclosing Party to seek an appropriate protective order.

Confidential Information, including permitted copies, shall be deemed the
property of the Disclosing Party.  The Recipient shall, within twenty (20) days
of a written request by the Disclosing Party, return all Confidential
Information (or any designated portion thereof), including all copies thereof,
to the Disclosing Party or, if so directed by the Disclosing Party, destroy
such Confidential Information.  The Recipient shall also, within ten (10) days
of a written request by the Disclosing Party, certify in writing that it has
satisfied its obligations under this Section.

If the Recipient fails to abide by its obligations under this Section, the
Disclosing Party shall be entitled to immediate injunctive relief, in addition
to any other rights and remedies available to it at law or in equity.

                                 12. ACCEPTANCE

Prior to the phased conversion (per the Project milestone schedule set forth in
Exhibit A) of 9-1-1 Services that will be performed by SCC, SCC shall conduct
the acceptance tests, described in Exhibit A, that reasonably demonstrate that
the 9-1-1 Services will be performed by SCC in accordance with the Performance
Metrics and the Acceptance Test Plan, both of which are also included in
Exhibit A.  Ameritech customer specific requirements, that are different than
the Base Services, will be communicated by Ameritech to SCC, with the
Acceptance Test Plan modified accordingly on a customer-by-customer basis.  New
Services, if added to this Agreement, shall be similarly tested prior to
Ameritech's acceptance of such in accordance with the New Services acceptance
criteria mutually agreed upon at such time by the Parties.  In the event SCC is
unable to demonstrate, within thirty (30) days of commencing the Acceptance
Test Plan, that the 9-1-1 Services will perform in accordance with the
Performance Metrics and that the Acceptance Test Plan criteria have been
successfully met, Ameritech shall have the option of extending the acceptance
testing period or of terminating this Agreement in accordance with Section
19.1.  In the event Ameritech elects to terminate this Agreement due to
non-acceptance of the 9-1-1 Services for Ohio, Ameritech shall be entitled to a
full and immediate refund of the NRE.

SCC warrants that it has no knowledge of any existing software viruses.  If SCC
becomes aware of any viruses in its products used in the performance of the
9-1-1 Services ordered by Ameritech, it shall so advise Ameritech in writing
immediately.  SCC shall be responsible for the consequences of its failure to
notify Ameritech in a timely fashion of a software virus of which SCC has
notice.  Upon learning of a virus in its software, SCC shall use its best
efforts to remedy it as soon as possible.

                            14.    INDEMNIFICATION

14.1.    GENERAL INDEMNIFICATION

Each Party shall defend, indemnify and hold harmless the other and the other's
corporate affiliates and their officers, directors, employees, and agents and
their successors and assigns against and from any and all losses, damages,
expenses, (including, without limitation, attorneys' fees and costs), claims,
suits and liabilities, whether based in contract or tort (including strict
liability), to the extent that such losses, damages, expenses, demands, claims,
suits and liabilities arise out of or in connection with (a) the indemnifying
Party's negligent or intentional acts or omissions, or those of persons
furnished by it, (b) the failure of the indemnifying Party to fully comply with
the terms and conditions of this Agreement, (c) assertions under Worker's
Compensation or similar laws made by persons furnished by the indemnifying
Party, or (d) the performance or nonperformance of the 9-1-1 Services under

right to conduct the defense of any such claim or action and all negotiations
for settlement or compromise, unless otherwise mutually agreed to in writing by
the Parties hereto.  However, Ameritech, at its own expense, shall have the
right to participate in the defense of any such suit or proceeding through
counsel of its choosing.  SCC shall indemnify and hold harmless Ameritech and
its officers, directors, employees, and agents and their successors and assigns
against and from any and all losses, liabilities, damages, claims, demands and

- --------------------------------------------------------------------------------




If any SCC product used to provide the 9-1-1 Services under this Agreement
becomes involved in any claim or action described above, or is held to
constitute a violation, infringement or misappropriation of a third party's
intellectual property rights and the use thereof is enjoined, then SCC shall,
at SCC's expense and option:

         (i)  procure the right to continue using said product so that its use
by SCC for Ameritech is lawful;

         (ii)  modify such product so that its use by SCC for Ameritech is
lawful (provided that such modification does not adversely affect the 9-1-1
Services provided); or

         (iii)  replace such product, at no charge to Ameritech, with equally
suitable, compatible and functionally equivalent products that lawfully may be
used by SCC for Ameritech.

                               15.   INSURANCE

of the applicable state, (b) employer's liability insurance with limits of at
least $[        ] each occurrence, (c) commercial general liability insurance
(including contractual liability and products liability coverage) with combined

property damage, and (d) if the use of motor vehicles is required,
comprehensive automobile liability insurance with combined single limits of at
least $[        ] per occurrence for bodily injury and property damage.  Neither
SCC nor SCC's insurer(s) shall have a claim, right of action or right of

Information Systems, Inc. and its corporate affiliates as additional insureds
and state:  "Ameritech Information Systems, Inc. is to be notified in writing
at least ten (10) days prior to cancellation of or any material change in this
policy".  Also, SCC must furnish certificates evidencing the foregoing
insurance coverage prior to commencement of performance.

If SCC fails to maintain the insurance required by this Section, Ameritech may
procure such insurance.  In such event, SCC shall promptly reimburse Ameritech
for any premiums and other charges paid by Ameritech for such coverage.

                 16.   LIABILITY AND LIMITATION OF LIABILITY

Ameritech caused by the grossly negligent acts or omissions of SCC or its
agents and subcontractors during the course of performing the 9-1-1 Services
rendered under this Agreement.

Neither Party shall require waivers or releases of any personal rights from
representatives of the other in connection with visits to its premises and both
Parties agree that no such releases or waivers shall be pleaded by them or
third persons in any action or proceeding.

charges and/or additional recurring charges, other fees as are reasonably
required.  Ameritech and SCC shall negotiate final terms which shall be

before it becomes effective and any associated work shall begin.

                             18.   FORCE MAJEURE

Neither Party shall be liable to the other for any delay or failure to perform
under this Agreement if the delay or failure to perform is without the fault or
negligence of the Party claiming excusable delay and is due to causes beyond
the control of said Party, including, but not limited to: acts of God, war,
acts of the government, fires, floods, epidemics, quarantine restrictions,
strikes, labor disputes (including collective bargaining issues), work
stoppages, and freight embargoes.

                        19.   TERMINATION/CANCELLATION

19.1.    TERMINATION BY AMERITECH

This Agreement (including the Purchase Option set forth as Exhibit C) may be
terminated by Ameritech in whole or part for any of the following reasons:

         (1)     if SCC defaults in its performance of any material obligation
required to be performed by SCC under this Agreement (including, but not
limited to, a failure by SCC to meet the specific acceptance or performance
requirements set forth in Exhibit A, or the warranties set forth in Section
13), and such default is not cured (or, in Ameritech's opinion, satisfactory
progress has not been made) within a thirty (30) day "cure period" following
receipt of Ameritech's written notice which describes the default; or

         (2)     in the event of any acquisition, or takeover of a controlling
interest in SCC by another entity, or a merger or other consolidation of SCC
into or with another entity, if the other or surviving entity, at Ameritech's
discretion is or could be deemed a competitor of Ameritech, or if the entity in
Ameritech's reasonable discretion is not financially or operationally capable
of assuming the services being provided hereunder; or

         (3)     if prior to the acceptance of 9-1-1 Services in Ohio Ameritech
is unable to reach appropriate accommodations with its union-represented
employees, on terms that are satisfactory to it, as determined at Ameritech's
sole discretion, in order to be able to undertake the commitments set forth in
this Agreement; or

         (4)     in the event continued performance under this Agreement would
cause Ameritech to be in violation of any court order or regulatory agency
having jurisdiction, or of any law, statute, ordinance or regulation; or

         (5)     in the event a mutually acceptable SOW, including all the
"Parts" listed on the Table of Contents of the SOW (Page A-1), is not developed
by September 1, 1994.




AGREEMENT                          PAGE 11
<PAGE>   15
                                                SCC/AMERITECH SERVICES AGREEMENT
- --------------------------------------------------------------------------------




In the event this Agreement is terminated by Ameritech in whole or part for any
of the reasons set forth above in this Section 19.1, SCC agrees, at Ameritech's
option, to sell Ameritech those SCC products and services desired by Ameritech,
under prices and terms consistent with the "Most Favored Customer" provisions
set forth in Section 21.2 below and those included in sections 1 to 41 of
Exhibit C, excluding the exhibits thereto.  The exhibits thereto will be
replaced with then current exhibits as mutually agreed upon by the Parties at
that time.In the event of an Ameritech termination as described above, SCC
further agrees to ensure an orderly transition of 9-1-1 Services back to
Ameritech, with minimal disruption to Ameritech's customers, in accordance with
the De-Implementation Plan set forth in Exhibit A.  SCC agrees to refund
Ameritech all unexpended NRE funds as of the effective termination date.  If
Ameritech partially (less than all five states) terminates this Agreement, it
shall be entitled to a partial refund of the NRE as set forth in Exhbit B
associated with each particular state for which this Agreement is terminated.
In the event of an Ameritech termination as described above, Ameritech will
have no payment obligations to SCC beyond the effective termination date and
will not be obligated to pay SCC, and will be entitled to a refund if already
paid, for any 9-1-1 Services, or other services, which fail to meet the
acceptance criteria, Performance Metrics or the warranties set forth in this
Agreement.  In the event of a conflict between this Section and Section 12,
Section 12 shall govern.

A termination of this Agreement by Ameritech does not in any way obligate
Ameritech to purchase any other SCC products and services following such
termination.  Only an exercise by Ameritech of its "Purchase Option", as
described in Section 8 above, obligates Ameritech to purchase SCC products and
services if 9-1-1 Services are not acquired from SCC hereunder.

Even if any of the above reasons (that allow Ameritech to terminate) may be
isolated to a particular state(s), Ameritech retains its right to terminate the
entire Agreement if it so chooses.

19.2.    TERMINATION BY SCC

This Agreement may be terminated by SCC if Ameritech defaults in its
performance of any material obligation required to be performed by Ameritech
under this Agreement (including, but not limited to, a failure by Ameritech to
pay SCC's undisputed invoices for services performed), and such default is not
cured (or, in SCC's opinion, satisfactory progress has not been made) within a
thirty (30) day "cure period" following receipt by Ameritech of SCC's written
notice which describes the default.

19.3.    CANCELLATION BY AMERITECH

In the event the regulatory, legal, labor or business conditions, ("business
conditions" being defined as market share, profitability, ability to grow
revenue, and the allocation of internal resources) under which this Agreement
is based upon change so that it would no longer be in Ameritech's best
interests to continue with the full term as stated herein, Ameritech shall have
the ability to cancel this Agreement in its entirety, or on a state-by-state
basis, at any time upon providing SCC prior written notice of its intention to
cancel, and the scope (i.e., # of states) of the cancellation, at least 180
days in advance of the Ameritech designated cancellation date.  Exhibit B, Part
3, "Cancellation Fee Schedule", sets forth Ameritech's cancellation fee payment
obligations to SCC in the event of such cancellation.  Payment by Ameritech of
the cancellation fee shall be the extent of Ameritech's liability to SCC in the
event of a cancellation hereunder.

In the event this Agreement is cancelled by Ameritech in whole or part in
accordance with this Section 19.3, SCC agrees, at Ameritech's option, to sell
Ameritech those SCC products and services desired by Ameritech, under prices
and terms consistent with the "Most Favored Customer" provisions set forth in
Section 21.2 below and those included in sections 1 to 41of Exhibit C,
excluding the exhibits thereto.  The exhibits thereto will be replaced with
then current exhibits as mutually agreed upon by the Parties at that time.  In
the event of an Ameritech cancellation, SCC further agrees to ensure an orderly
transition of 9-1-1 Services back to Ameritech, with minimal disruption to

- --------------------------------------------------------------------------------




Ameritech's customers, in accordance with the De-Implementation Plan set forth
in Exhibit A.  SCC agrees to refund Ameritech all unexpended NRE funds as of
the effective cancellation date.  If Ameritech partially (less than all five
states) cancels this Agreement, it shall be entitled to a partial refund of the
NRE as set forth in Exhibit B associated with each particular state this
Agreement is cancelled for.  In the event of an Ameritech cancellation,
Ameritech will have no payment obligations to SCC beyond the effective
cancellation date for that portion of the Agreement cancelled.

A cancellation of this Agreement by Ameritech does not in any way obligate
Ameritech to purchase any other SCC products and services following such
cancellation.  Only an exercise by Ameritech of its "Purchase Option", as
described in Section 8 above, obligates Ameritech to purchase SCC products and
services if 9-1-1 Services are not acquired from SCC hereunder.

                                 20.   TAXES

The fees and charges under this Agreement do not include any sales, use,
excise, transaction or other similar taxes levied against or upon the
furnishing or receipt of services pursuant to this Agreement.  If such taxes
are applicable, they shall be separately stated on the invoice to Ameritech and
Ameritech shall pay them.  Ameritech shall have no obligation to pay any taxes
or fees:

         (a)     that are based upon SCC's net or gross income or gross
receipts;

         (b)     that are franchise taxes or other taxes based on SCC's
corporate existence or status;

         (c)     that are personal property taxes on licensed software; and

         (d)     that are due in whole or in part because of any failure by SCC
or its agents to file any return or information required by law, rule or
regulation.

         Ameritech shall reimburse SCC for any penalties or interest actually
levied upon SCC only if Ameritech's acts or omissions solely caused such
interest or penalty to be levied.

                           21.   GENERAL PROVISIONS

21.1.    INDEPENDENT CONTRACTORS

The Parties are performing pursuant to this Agreement only as independent
contractors.  Each Party has the sole obligation to supervise, manage,
contract, direct, procure, perform, or cause to be performed its obligations
set forth in this Agreement, except as otherwise provided herein or agreed upon
by the Parties.  Except as specified in this Agreement, nothing set forth in
this Agreement shall be construed to create the relationship of principal and
agent between SCC and Ameritech.  Neither Party shall act or attempt to act or
represent itself, directly or by implication, as an agent of the other Party or
its affiliates or in any manner assume or create, or attempt to assume or
create, any obligations on behalf of, or in the name of the other Party unless
so instructed by the other Party in writing or allowed under this Agreement.
Nothing herein is intended or shall be construed to create any partnership,
agency, or joint venture relationship between the Parties.  Neither Party or a
Party's subcontractor, or the employees of any of them, shall be deemed for any
purpose to be employees of the other Party.  Each Party shall be solely
responsible for the withholding or payment of all applicable federal, state,
and local personal income taxes, social security taxes, unemployment and
sickness disability insurance, and other payroll taxes with respect to its own
employees.

                                               ]

21.3.    ASSIGNMENT

Except as provided otherwise in this Section, neither Party shall assign,
subcontract, out-source, or otherwise transfer any rights or obligations under
this Agreement without the other Party's prior written consent, which consent
shall not be unreasonably withheld.

Notwithstanding the above, Ameritech may, at no charge and without SCC's prior
written consent, assign its rights and delegate its duties under this
Agreement, either in whole or part, to any Ameritech's Affiliate.  For purposes
of this Agreement, "Ameritech Affiliate" shall mean any affiliate  of the
Ameritech Corporation, or any company which is greater than fifty percent (50%)
directly or indirectly owned by the Ameritech Corporation.  Upon the acceptance
of such rights and the assumption of such duties by the assignee, the assignor
shall be released and discharged, to the extent of the assignment, from all
further duties and liability under this Agreement, except for Ameritech's
obligations under Section 11, entitled "Confidentiality and Nondisclosure".

This Agreement shall be binding upon the Parties' respective successors and
assigns.

21.4.    UNBUNDLING OF SERVICES

Both Parties will commit to ensuring the integrity of 9-1-1 Services throughout
the term of this Agreement and will work to minimize the impacts to customers
as telecommunications networks are further disaggregated through unbundling and
the introduction of numerous competitive access providers.  The focus of the
Parties shall be on working cooperatively with each other and with all
alternative providers to facilitate the saving of lives and property.

21.5.    ESCALATION PROCEDURES AND NOTICES

Any dispute between the Parties under the terms of this Agreement shall attempt
to be resolved first by the Project Managers.  It is the understanding of both
Parties that in the event a dispute cannot be resolved by the Project Managers,
then it shall be escalated up the levels of management as shown in Exhibit A.

All notices or other communications required or permitted to be given under
this Agreement shall be in writing (unless otherwise specifically provided
herein) and delivered or addressed as follows:

All notices or other communications shall be deemed effectively given:  (i)
when delivered, if personally delivered (except that notices received after
3:00 p.m. local time will be deemed received on the following business day);
(ii) on the date of delivery (or, if refused, the refusal date shown on the

21.6.    FAIR MARKET VALUE

The price for the purchase of the tangible and intangible assets referred to in
this Agreement shall be the Fair Market Value as agreed upon by Ameritech and
SCC.  If Ameritech and SCC are unable to agree upon a price, each shall select
an appraiser knowledgeable in the valuation of those types of assets and the
two appraisers shall attempt to reach agreement on the Fair Market Value.  If
the two appraisers are unable to reach agreement, they shall select a third
appraiser who also shall be knowledgeable in the valuation of such assets.  The
three appraisers shall then determine the Fair Market Value, but if they are
unable to agree, the Fair Market Value shall be set by the third appraiser.
Each Party shall bear the expense of the appraiser selected by it, and the
Parties shall split the expense of the third appraiser.

21.7.    RECORDS AND AUDITS

on-site audits and reviews of the Project records used for providing the 9-1-1
Services including the billings of Monthly Base Record charges, the data
protection and security measures, etc.

21.8.    EQUAL OPPORTUNITY

To the extent Ameritech is required by law to extend any Equal Opportunity
Employment requirements to suppliers or vendors, and such is required to
include SCC as a provider of 9-1-1 Services, SCC shall comply with all
applicable portions of such requirements and the nondiscrimination compliance
provisions.  Ameritech shall inform SCC of such requirements in writing as soon
as it becomes known to Ameritech.

21.9.    COMPANY RULES

SCC's employees and agents shall comply with all of Ameritech's, governmental
security, and plant requirements, rules and regulations provided to SCC while
on Ameritech's premises and Ameritech's employees shall comply with all of
SCC's, governmental security, and plan requirements, rules and regulations
provided to Ameritech while on SCC's premises.

in agreeing to the original provision.  The remaining provisions of the
Agreement shall continue in full force and effect.

21.17.   JOINT WORK PRODUCT

SCC; accordingly, in the event of ambiguities, no inferences will be drawn

The price for 9-1-1 Services is made up of two elements: a Non-Recurring
Engineering (NRE) charge, and a per month per Base Record charge for each Base
Record for which SCC provides the Base Service.  The NRE is a one time charge
for the establishment of Base Services.  Even though the full NRE charge will
be payable to SCC by Ameritech upon full contract signing by the Parties, SCC
and Ameritech acknowledge that the Services associated with the NRE payment
will be performed over several months following contract signing.
Consequently, SCC agrees to provide Ameritech a statement each month showing
the percentage of NRE funds expended for that month and on a cumulative "to-
date" basis.  No costs shall be accumulated by SCC against the NRE prior to the
July 1, 1994, and the only costs to be accumulated against the NRE, from July
1, 1994 to the date a mutually acceptable SOW is developed and incorporated
into this Agreement, are those SCC costs associated with developing the SOW
which SCC agrees to properly substantiate.  The Monthly Base Service Charge per
Base Record is calculated on a ten (10) year Agreement term.

Ameritech will be invoiced at the threshold levels on the dates shown above if
minimum levels have not been met, if the cause of the Records not being ready
for SCC provisioning is due to Ameritech's negligence or delay.  Accordingly,
this monthly billing to Ameritech by SCC will be based on the actual number of
Base Records for which Base Services are being provided, or on the "threshold
level" number of records as stated in the above Threshold Table, whichever is
greater.  If the Records are not ready at the above threshold dates because of
the fault of SCC, Ameritech also shall receive a credit to be applied against
subsequent SCC invoices in the amount of 1/30 of the monthly charge for the
Records being added at the threshold for each day of delay until the Records
are ready for SCC provisioning.

IV.    Regularly Scheduled Audit Procedures

(Procedures will be due as part of the Operations Plan to be completed by
January 1, 1995.)

                       PART 3:  CANCELLATION FEE SCHEDULE


AMERITECH CANCELLATION FEES

In the event Ameritech elects to cancel the Agreement in accordance with
Section 19.3, Ameritech shall pay SCC a Cancellation Fee.  The Cancellation Fee
shall be calculated, as of the effective cancellation date, as follows:

       1)     Take the total number of months which SCC has been providing and
              billing Ameritech for 9-1-1 Services as of the effective
              cancellation date.

       2)     Multiply the number of months in #1 above by the # of Base
              Records serviced and invoiced by SCC each month.

       3)     Multiply the result in #2 above by the applicable "Cancellation
              Rate" as set forth in the following table:

*      Year 1 of the above "Cancellation Period" begins immediately following
       expiration of the "Purchase Option" period.  Expiration of the Purchase
       Option period is scheduled for 4/1/95, based upon having a mutually
       acceptable SOW by 9/1/94 and 1/1/95 Ohio 9-1-1 Service implementation
       and acceptance date.  The Year 1, Year 2, Year 3, etc. periods will be
       extended should any of these key milestone dates slip, thus causing the
       Purchase Option period expiration date to occur later than expected.

*      In the event the Ameritech cancellation is for less than all five (5)
       states within the Ameritech Region, the same formula is used, but the
       number Base Records serviced and invoiced by SCC each month, only for
       the canceled states, applies.

EXAMPLES:

The following examples assume that the planned implementation and acceptance
dates are met, that the actual # of Base Records serviced and billed by SCC
equals the Base Record volume and timing commitments as set forth in the
"Threshold Table" in Part 2 of this Exhibit B and that there is no Base Records
growth.  Specifically:

         of data and population density, price will be negotiated on a case by
         case basis at a later date.

         government contracts and subcontracts.

2.       CERTIFICATION OF NON-SEGREGATED FACILITIES.

         SCC certifies that it does not and will not maintain any facilities it
         provides for its employees in a segregated manner or permit its
         employees to perform their services at any location under its control,
         where segregated facilities are maintained, and that it will obtain a

         promulgated in its place.

5.       UTILIZATION OF MINORITY AND WOMEN'S BUSINESS ENTERPRISES.

         a)       It is the policy of the government that minority and women's

                  opportunity to participate in the performance of government
                  contracts.

         b)       SCC shall use its best efforts to carry out this policy in the
                  award of its subcontracts to the fullest extent consistent

- --------------------------------------------------------------------------------


         a)       It is the policy of the United States that small business
                  concerns and small business concerns owned and controlled by
                  socially and economically disadvantaged individuals shall have
                  the maximum practicable opportunity to participate in the
                  performance of contracts let by the Federal agency.

         b)       SCC hereby agrees to carry out this policy in the awarding of
                  subcontracts to the fullest extent consistent with the
                  efficient performance of this Agreement. SCC further agrees to
                  cooperate in any studies or surveys as may be conducted by the
                  Small Business Administration or the contracting agency which
                  may be necessary to determine the extent of SCC's compliance
                  with this clause.

         c)       (1)      As used in this Agreement the term "small business

                           pursuant to Section 3 of the Small Business Act and 
                           relevant regulations promulgated pursuant thereto.

                  (2)      The term "small business concern owned and controlled

                           publicly owned business, at least 51% of the stock of

                           the Small Business Act.

         d)       SCC acting in good faith may rely on written representation by
                  their subcontractors regarding their status as a small
                  business concern or a small business concern owned and
                  controlled by socially and economically disadvantaged

               or any company that is owned in whole or in part by BellSouth
               Corporation or by one or more of its direct or indirect
               subsidiaries.  Any Affiliated Company may place orders under
               this Agreement to buy Emergency Services as hereinafter defined.
               All references to "Buyer" in this Agreement shall be deemed to
               include the Affiliated Company placing the order.  Such orders
               are subject to the terms and conditions of this Agreement and as
               to such orders, the Affiliated Company becomes "Buyer"
               hereunder.  Each order shall constitute a separate, distinct and
               independent contract between Seller and the Buyer placing the
               order and each Buyer shall be the sole obligor with regard to
               meeting the obligations of any order placed by such Buyer.


SECTION  2. TERM OF AGREEMENT

2.01           The term of this Agreement shall commence on August 1, 1995, and
               shall, except as otherwise provided herein, continue in effect
               thereafter through July 31, 2005, inclusive.



2.02           This Agreement contemplates the future execution by Buyer and
               Seller of one or more written Letter Purchase Orders.  Each
               Letter Purchase Order shall be executed by both parties and
               shall contain at a minimum the information specified in this
               Agreement.  All transactions between Buyer and Seller during the
               term of this Agreement shall be covered by this Agreement and
               any applicable Letter Purchase Order unless the parties agree
               otherwise in writing.

2.03           Each properly executed Letter Purchase Order shall be deemed,
               upon its execution, to be incorporated into this Agreement.  If
               the Letter Purchase Order conflicts with the terms and
               conditions of this Agreement, the terms and conditions of this
               Agreement shall control unless otherwise agreed to under a
               "Special Considerations" section of the Letter Purchase Order.

               parties.  The Project Managers shall be responsible for
               insuring the continuity of communications between the parties
               as the project proceeds.  Each Letter Purchase order shall

               Purchase Order should state the maximum total expenditure
               authorized, which is understood to mean (1) a dollar amount or

2.06           The specifications for the Emergency Services to be provided.


2.07           Buyer, without prejudice to any right or remedy on account of
               any failure of Seller to perform its obligations under this
               Agreement, may at any time terminate the performance of the work
               under any Letter Purchase Order, in whole or in part, by written
               notice to Seller specifying the extent to which the performance
               of the work is terminated and the date upon which such
               termination becomes effective.  In the event of such
               termination, other than for the failure of Seller to perform its
               obligations under this Agreement, Seller shall be entitled to
               payment for Emergency Services rendered prior to the effective

               payment of such amounts by Buyer shall be in full settlement of

               profit.

               Buyer.  Any transfer of ownership of property acquired by Seller
               to perform the requirements identified in a Letter Purchase
               Order will be addressed in the Letter Purchase Order.

SECTION 14.  ASSIGNMENT BY SELLER

14.01          Except for Seller's assignment to a third party acquiring all or

               hereunder without first obtaining Buyer's prior written consent,

               deliver to Buyer written notice of Seller's intent to assign, at

               due to Seller shall be made by Seller if such assignment

               obligations of Seller hereunder or attempts to prevent Buyer
               from dealing solely and directly with Seller on all matters
               pertaining to this Agreement, including the negotiation of
               amendments to this Agreement or the settlement of amounts due
               either party by the other hereunder.

14.02          Seller agrees not to subcontract the Emergency Services to be
               performed, in whole or in part, without written request to and
               the prior written consent of Buyer's Project Manager designated
               in individual Letter Purchase Orders.  Seller shall remain
               primarily liable to Buyer for the performance of all
               subcontracted Emergency Services provided pursuant to this
               Agreement.

               consent, to any present or future Affiliated Company or
               successor company of Buyer.  Buyer shall give Seller written
               notice of such assignment or delegation.  The assignment shall

               Buyer may then or thereafter have as to Emergency Services
               ordered by Buyer prior to the effective date of the assignment.
               Upon the written notice to the Seller, Buyer shall be released

               further duties under this Agreement, except with respect to

               other intellectual property, express or implied, are granted by
               Buyer to Seller under this Agreement.


SECTION 17.  SUPPLIER OVERDEPENDENCY

17.01          Because Buyer has no way of ascertaining Seller's dependency
               on Buyer for revenues from sales in proportion to revenues
               from Seller's other customers and in order to protect Buyer
               from a situation in which Seller is over-dependent on Buyer
               for said sales, Seller agrees to release and hold harmless
               Buyer from any and all claims relating to Seller's financial
               stability, which may result from Buyer's termination of this
               Agreement for any reason whatsoever.

SECTION 19.  NON-EXCLUSIVE RIGHTS

19.01          It is expressly understood and agreed that this Agreement does
               not grant Seller an exclusive privilege to sell to Buyer any
               or all Emergency Services of the type described in Section 3
               entitled "EMERGENCY SERVICES" which Buyer may require.  Buyer
               reserves the right to contract with other suppliers for the
               procurement of comparable services.  In addition, Buyer shall

               such as employment, Social Security, and other payroll taxes,
               including applicable contributions from such person when
               required by law.  Seller shall not subcontract work to be
               performed without Buyer's written permission.
               
SECTION 23.  SECURITY

23.02          Seller shall conduct, at Seller's expense, background
               investigations on Seller's personnel performing work on
               Buyer's premises prior to supplying such personnel to Buyer.
               At Buyer's request, Seller shall provide copies of the
               background investigations to Buyer.
               
23.03          Seller shall not assign any personnel with records of criminal
               conviction(s) to Buyer's premises without advising Buyer of
               the nature and gravity of the offense.
               
23.04          In fulfilling the obligations under this Section, both parties
               shall comply with all laws, rules, and regulations relating to
               the making of investigative reports and the disclosure of the
               information contained therein.  Each party shall indemnify,
               defend, and hold the other party harmless against any wrongful
               disclosure by the offending party, its employees, and/or agents
               of said reports and the information contained therein.

23.05          At Buyer's request, Seller shall promptly remove from Buyer's
               premises any employee of Seller to whom Buyer does not wish to
               grant access to its premises, or who, in Buyer's opinion, has
               been unacceptable, negligent, dishonest, or otherwise
               unsatisfactory in performing his/her duties hereunder.  Such a
               request for removal from Buyer's premises shall in no way be
               interpreted as a request by Buyer for Seller to discipline the
               employee in any way.
               
SECTION 24.  NONDISCRIMINATION COMPLIANCE

24.01          Seller agrees to comply with the applicable provisions of the

SECTION 25.  CONFLICT OF INTEREST

25.01          Buyer and its affiliated companies do business with many
               contractors and suppliers.  It is a fundamental policy of
               Buyer that such dealings shall be conducted on a fair and
               non-discriminatory basis, free from improper influences, so
               all participating contractors and suppliers may be considered
               on the basis of the quality and overall cost of their product
               or service.



                                       12
<PAGE>   16
25.02          Buyer's policy is to seek out and obtain technically suitable
               products and services at the lowest overall cost.  Accordingly,
               Buyer will not recognize any oral agreement; any conversations
               with Buyer's employees or representatives shall not be construed
               to imply a commitment or obligation on behalf of Buyer.  Any
               information disclosed or made known to Buyer shall be deemed as
               public and nonproprietary.  Information shall not be received in
               confidence, unless a prior written agreement authorizing such
               exchange of information has been executed by an authorized
               representative of Buyer.

25.03          Buyer is committed to doing business with contractors and 
               suppliers in an atmosphere in keeping with the highest standards
               of business ethics.  Therefore, it is Buyer's policy that our
               employees shall not accept from customers; from suppliers of
               property, goods, or services; or from other persons any gifts,
               benefits, or unusual hospitality that may in any way tend to
               influence or have the appearance of influencing them in the
               performance of their jobs.

25.04          Those employees of Buyer authorized to make purchases or
               negotiate contracts are aware of this policy, and your
               cooperation is solicited in order to forestall any embarrassing
               situations.

SECTION 26.  CHOICE OF LAW/VENUE

26.01          The validity, construction, interpretation, and performance of
               this Agreement shall be governed by and construed in accordance
               with the domestic laws of the State of Georgia.

26.02          The jurisdictional venue for any legal proceedings involving
               this Agreement shall be held in any applicable state or
               federal court located in Fulton County, State of Georgia.

SECTION 28.  RIGHT OF ACCESS

28.01          Both Seller and Buyer shall permit reasonable access to the
               other's facilities in connection with work hereunder.  No
               charge shall be made for such visits. It is agreed that prior 
               notification will be given when access is required.  Seller 
               agrees to remove any of its employees at Buyer's request.

SECTION 29.  DEFAULT

29.01          In the event Seller shall be in breach or default of any of the
               terms, conditions, or covenants of this Agreement or any Letter
               Purchase Orders, and such breach or default shall continue for a
               period of thirty (30) days after the giving of written notice to
               Seller thereof by Buyer, then in addition to all other rights
               and remedies of law or equity or otherwise, Buyer shall have the
               right to cancel this Agreement or any such Letter Purchase
               Orders placed by Buyer without any charge, obligation, or
               liability whatsoever, except as to the payment for Emergency
               Services already received and accepted by Buyer.

SECTION 30.  COMPLIANCE WITH LAWS

30.01          Seller shall comply with the provisions of all applicable
               federal, state, county and local laws, ordinances,

               Seller's obligations as an employer with regard to the health,
               safety and payment of its employees, and identification and
               procurement of required permits, certificates, approvals, and
               inspections of Seller's performance of this Agreement.
               Notwithstanding of whether a specification is furnished, if
               Emergency Services furnished are required to be registered in
               a prescribed manner, Seller shall comply with federal law and
               applicable state or local law.  Seller shall indemnify Buyer
               for, and defend Buyer against, any loss or damage sustained
               because of Seller's noncompliance.

               rights from representatives of the other in connection with

               party shall require any representative of the other party to
               sign a personal "nondisclosure agreement." No such releases or
               waivers shall be pleaded by Seller or Buyer or third persons in

               under the terms of this Agreement on any occasion or occasions
               shall be construed to be a waiver of the same or any other
               option, right, or privilege on any other occasion.

SECTION 33.  SEVERABILITY

33.01          If any of the provisions of this Agreement shall be invalid or
               unenforceable under the laws of the jurisdiction applicable to
               the entire Agreement, such invalidity or unenforceability
               shall not invalidate or render unenforceable the entire
               Agreement but rather the entire Agreement shall be construed
               as if not containing the particular invalid or unenforceable
               provision or provisions, and the rights and obligations of
               Seller and Buyer shall be construed and enforced accordingly.

               explosion, war, strike, embargo, government requirement, civil
               or military authority, act of God, or other similar causes
               beyond Seller's or Buyer's control (hereinafter "Condition(s)").

               perform shall give immediate notice to the other party, and the
               party affected by the other's delay or inability to perform may
               elect to: (1) terminate this Agreement or part thereof as to
               Emergency Services not already received; (2) suspend this
               Agreement for the duration of the Condition, buy or sell
               elsewhere material or services comparable to those to be
               obtained under this Agreement, and deduct from any commitment
               the quantity bought or for which commitments with other
               suppliers have been made; or (3) resume performance of this
               Agreement once the Condition ceases with an option in the
               affected party to extend the period of this Agreement up to the

efficiency of the system for delivery of the Services will be maintained and

     The Cancellation Fee Schedule, attached hereto and marked as Exhibit B and
incorporated herein, sets forth the cancellation fee, if any, that would be
payable by AMCI to SCC in the event AMCI exercises its right to cancel this
Agreement pursuant to section 3.2.3 hereunder.

projected date of its availability; (c) a proposed implementation schedule; (d)

AMCI of director level or above.
 
2.4  LETTER OF AGENCY (EXHIBIT D).
 
     AMCI shall provide SCC with a Letter of Agency ("LOA") similar in form and
substance to that which is set forth in Exhibit D, which letter will enable SCC
to perform the Services as a limited agent for AMCI. The LOA shall: (a) not be
released by SCC or used except as authorized by this Agreement; (b) be deemed
revoked upon termination of this Agreement or delivery to SCC of written notice
of AMCI's election in this regard; and (c) be returned to AMCI upon AMCI's
request, or destroyed by SCC upon termination of this Agreement or the
revocation notice described herein.
 
2.5  ORDERLY TRANSITION.

perform, the Services (described below in subparagraphs 2.5.1(a) and 2.5.1(b)
which are more fully described in Exhibit A) in whole or in part, in each or any
of AMCI's Regions ("Transitioned Services"). AMCI may not exercise said option
earlier than one (1) year after the date on which a particular Qualified PSAP,
which has requested Phase I E9-1-1 Service, is turned-up and Services are
deployed by SCC. In the event AMCI properly makes such an election, and to the
extent determined by AMCI in its sole discretion, AMCI shall substitute its
performance for that of SCC. Thereafter AMCI shall be responsible for the
Transitioned Services in lieu of SCC, and except as otherwise expressly provided
herein, SCC shall be relieved of its obligations therefore.
 
                                        3
<PAGE>   6
 
The pricing discounts related to AMCI's exercise of this option are described in
section 4 hereunder. Transitioned Services include:
 
          (a) network engineering, design and pANI Translations, including
     identification of specific network interconnections required from AMCI to
     specific E9-1-1 networks, Qualified PSAPs, appropriate engineering of
     connections for traffic capacity and coordination of pANI translations into
     the required AMCI network elements;
 
          (b) LEC/CLEC and pANI coordination and pANI assignment, including
     coordination of network ordering, installation testing and turn-up as well
     as coordination of all pANI assignments and confirmation with all LEC/CLEC
     interconnect requirements and pANI assignments;
 
  2.5.2  ORDERLY TRANSITION.
 
     In the event AMCI properly exercises its options related to sections 2.5.1
or 2.5.2, then to the extent it is relevant and applicable thereto, SCC will
cooperate in the orderly transition of the Transitioned Services to AMCI or its
agent and will make reasonable efforts to minimize any disruption of AMCI's
wireless 9-1-1 service. At such time that AMCI exercises any option in this
regard, and with respect to the AMCI-relevant data and databases that SCC
legally controls hereunder, SCC will deliver to AMCI such data contained in such
databases, and other information, that is necessary to allow SCC to be
substituted in this regard; provided, however that SCC shall not be obligated to
do so if such delivery or other performance would violate the provisions of the
confidentiality provisions contained herein, result in a breach of contract to
which SCC is a party as of the date hereof, violate any other law or private
right, would convey to AMCI any intellectual property or other right to which
AMCI is otherwise unentitled hereunder, or would otherwise unreasonably subject
SCC to civil or criminal prosecution. Such data and information shall include
but not be limited to "AMCI Results", as defined herein below, along with the
data needed to perform said Services in a readable file that is convertible with
commercially available software which data is current as of the date of such
substitution. Upon AMCI's request, and subject to the above limitations, SCC
will provide to AMCI whatever explanatory information or functional tools in
SCC's possession or legitimate control which are reasonably necessary for AMCI
to fully exploit the database contents.
 
     Unless otherwise agreed by the Parties, after such time as AMCI becomes
responsible for the Transitioned Services as contemplated herein, SCC would
continue to upload to AMCI's SCP(s) on AMCI's behalf the mapping files which
operate in connection with the location-based application software being
utilized by the Parties as of that date, or a reasonable substitute therefore,
which SCC is capable of and willing to support.
 
     Following termination, cancellation or expiration of this Agreement, or in
connection with an Orderly Transition, if AMCI requests that SCC continue to
provide any portion or all of the Services, for which SCC would not otherwise be
contractually obligated to provide under the terms and conditions of this
Agreement, AMCI shall compensate SCC for such Services at the same rate as that
set forth herein for such Services.
 
                            3. TERM AND TERMINATION
 
3.1  TERM.
 
     Unless earlier terminated or canceled in accordance with this section, the
term of this Agreement shall begin upon the Effective Date as first stated
herein and continue until December 31, 2000. If either Party terminates this
Agreement according to the provisions of this section, then both Parties agree
to participate in the orderly shutdown and transition of products and services
as provided herein. Following this initial term, the Agreement shall
automatically renew for continuous twelve (12) month terms unless terminated at
the end of a renewal term upon no less than sixty (60) days advance written
notification by the terminating Party.

<PAGE>   7
 
3.2  TERMINATION AND CANCELLATION.
 
  3.2.1  TERMINATION BY AMCI.
 
     This Agreement may be terminated by AMCI in whole or part for any of the
following reasons:
 
          (1) if SCC defaults in its performance of any material obligation
     required to be performed by SCC under this Agreement (including, but not
     limited to, a failure by SCC to meet the specific acceptance or performance
     requirements set forth in Exhibit A, or the warranties set forth herein),
     and such default is not cured (or, in AMCI's reasonable opinion,
     satisfactory progress has not been made as part of the escalation
     procedures described in Exhibit A) within a thirty (30) day "cure period"
     following receipt of AMCI's written notice which describes the default; or
 
          (2) in the event of any acquisition, or takeover of a controlling
     interest in SCC by another entity, or a merger or other consolidation of
     SCC into or with another entity, if the other or surviving entity, at
     AMCI's discretion is or could be deemed a competitor of AMCI or its
     Affiliates in the telecommunications industry, or if the entity in AMCI's
     reasonable discretion is not financially or operationally capable of
     assuming the services being provided hereunder; or
 
          (3) in the event continued performance under this Agreement would
     cause AMCI to be in violation of any court order or regulatory agency
     having jurisdiction, or of any law, statute, ordinance or regulation,
     except that any failure of the Tandem, Signal Soft, SCC solution
     contemplated herein shall not be deemed such a cause which circumstance is
     addressed in and controlled by section 3.2.2 herein below.
 
     In the event of an AMCI termination as described above, AMCI will have no
payment obligations to SCC beyond the effective termination date and will not be
obligated to pay SCC.
 
     In the event of an AMCI termination as described above, SCC will cooperate
in the orderly transition of such terminated services in accordance with the
applicable provisions of section 2.5.2 herein.
 
     A termination of this Agreement by AMCI does not in any way obligate AMCI
to purchase any other SCC products and services following such termination.
 
     Even if any of the above reasons (that allow AMCI to terminate) may be
isolated to a particular state(s), AMCI retains its right to terminate the
entire Agreement if it so chooses.
 
  3.2.2  TERMINATION BY AMCI -- NON-INTEGRATION WITH SCP NETWORK.
 
     SCC understands that AMCI's E9-1-1 network must operate in combination with
equipment, hardware and software provided by Tandem, Signal Soft and Lucent to
AMCI. SCC agrees to cooperate fully with such other suppliers to the extent
necessary to assure that AMCI's E9-1-1 network will function in accordance with
the specifications and requirements of this Agreement, any applicable TIA or
Bellcore standards and specifications, and any standards for E9-1-1, Phase I
services mandated by federal, state or local laws, ordinances, rules and
regulations. In the event that the SCC, Tandem, Signal Soft and Lucent solution
cannot perform in an integrated manner in the AMCI network and thereby process
E9-1-1 calls per the applicable standards for Phase I E9-1-1, AMCI shall provide
SCC with written notice of said non-integration. Immediately after SCC's receipt
of such notice, the Parties will, in good faith, jointly explore an alternative,
compliant solution for processing E9-1-1 calls which solution would, to the
extent practical, designate SCC as the provider of the database management
services defined in the SOW, subject to the terms and conditions described below
in this subsection. AMCI will give due consideration to the opinions and
recommendations of SCC in connection with the selection of an alternative,
compliant solution, but AMCI will have sole discretion as to its final choice.
 
     If said alternative solution contemplates an E9-1-1 call processing
platform whereby said database management services, as defined in the SOW, can
be performed as a "stand alone" functionality and not bundled with other
services, then SCC will have the right to provide those database services at the
same costs and under terms and conditions that are no less favorable to AMCI
than those set forth in this Agreement.
 
                                        5
<PAGE>   8
 
     If such alternative solution is provided by a third party and involves a
platform whereby the third party vendor providing such solution uses database
management services as a bundled offering with SCP(s) and location-based
software to accomplish E9-1-1 call processing functionality, then SCC would only
have the right to provide such database management services if: (a) SCC and AMCI
jointly obtain consent from said third party vendor to un-bundle said database
management services; (b) using SCC would not deprive AMCI of its options for
selecting an alternative, compliant solution as described herein; (c) SCC would
agree to provide such services under terms and conditions that are no less
favorable to AMCI than that set forth herein; (d) SCC would agree to provide
such services at a cost that, when added to the third party vendor's total cost
to provide the bundled service, minus the price at which said third party would
otherwise provide database management services, would not exceed the third party
vendor's total original cost for the bundled services; and (e) SCC would agree
to provide such services in a manner that equals or exceeds the quality of
database management services offered as part of the bundled service.
 
     If SCC and AMCI cannot provide or mutually agree to a plan to provide an
alternate, compliant functionality within a thirty (30) day period, measured
from the date on which SCC receives said notice of non-integration, which period
may be extended by mutual agreement of the Parties, then AMCI may terminate the
portion of this Agreement affected by such non-integration upon written notice
of AMCI's desire to terminate, which notice shall state the effective date of
such termination and the reasons supporting such termination. Such a termination
shall not be deemed a default by SCC. AMCI may exercise its termination rights
hereunder for a period up to one hundred twenty (120) days after successful
completion of the First Office Application (FOA). For the purposes of this
clause, successful completion of the FOA means successful completion of the
testing based upon the Signal Soft Acceptance test document "W911-TP-Acceptance
Test" dated December 16, 1997 and the commercial deployment of the SCC, Tandem,
Signal Soft and Lucent solution with a Qualified PSAP and live AMCI customer
traffic on a duplex SCP configuration. In the event AMCI exercises its right of
termination in this regard, AMCI shall be responsible for paying SCC all the
fees otherwise payable in accordance with the provisions of section 4 herein for
Services rendered as of the date of said termination.
 
     Appendix A-1 is an E9-1-1 System Supplier Responsibility Matrix that lists
the start-up and ongoing system responsibilities as between the various parties
involved in the SCC, Tandem, Signal Soft, Lucent and AMCI solution. For purposes
of this Agreement, said matrix shall govern any disputes regarding E9-1-1
supplier responsibility as between SCC, Tandem, Signal Soft, Lucent and AMCI. In
the event of a dispute not involving any one or more of such third parties but
which is solely between SCC and AMCI over SCC's and AMCI's respective
responsibilities as set forth in said matrix as opposed to that which is set
forth in Exhibit A, that which is set forth in Exhibit A will control said
dispute. SCC shall provide for those responsibilities described in Exhibit A at
no additional charge beyond the contracted Non-recurring and Recurring fees
listed in section 4 herein below.
 
  3.2.3  CANCELLATION BY AMCI.
 
     In the event the regulatory, legal, labor or business conditions,
("business conditions" being defined as market share, profitability, ability to
grow revenue, and the allocation of internal resources) under which this
Agreement is based upon change so that it would no longer be in AMCI's best
interests to continue with the full term as stated herein, AMCI shall have the
ability to cancel this Agreement in its entirety, or on a state-by-state basis,
at any time upon providing SCC prior written notice of its intention to cancel,
and the scope (i.e., # of states) of the cancellation, at least 180 days in
advance of the AMCI designated cancellation date. Exhibit B, "Cancellation Fee
Schedule", sets forth AMCI's cancellation fee payment obligations to SCC in the
event of such cancellation. Payment by AMCI of the cancellation fee shall be the
extent of AMCI's liability to SCC in the event of a cancellation hereunder.
 
     The Parties acknowledge and agree that the cancellation fee is not a
penalty and is, and shall be deemed, liquidated damages which damages are
reasonably based on the Parties' best estimate of what SCC's damages would be as
a result of AMCI's cancellation for Business Conditions.
 
                                        6
<PAGE>   9

     In the event this Agreement is cancelled by AMCI in whole or part in
accordance with this Section, SCC agrees, at AMCI's option, to sell AMCI those
SCC products and services, to which SCC has the ability and legal capacity to
sell, and which are desired by AMCI, under prices and terms consistent with the
"Most Favored Customer" provisions set forth herein. Except as may otherwise be
provided hereunder, in the event of an AMCI cancellation, AMCI will have no
payment obligations to SCC beyond the effective cancellation date for that
portion of the Agreement cancelled.
 
     A cancellation of this Agreement by AMCI does not in any way obligate AMCI
to purchase any other SCC products and services following such cancellation.
 
  3.2.4  TERMINATION BY SCC.
 
     This Agreement may be terminated by SCC if AMCI defaults in its performance
of any material obligation required to be performed by AMCI under this Agreement
(including, but not limited to, a failure by AMCI to pay SCC's undisputed
invoices for services performed), and such default is not cured (or, in SCC's
reasonable opinion, satisfactory progress has not been made) within a thirty
(30) day "cure period" following receipt by AMCI of SCC's written notice which
describes the default.
 
                              4. FEES AND PAYMENT
 
4.1  FEES FOR SERVICES.
 
  4.1.1
 
     AMCI will pay SCC the fees and charges in the amounts and in the manner set
forth below:
 
A. NON-RECURRING ENGINEERING FEE ("NRE") FOR EACH MOBILE SWITCHING CENTER
   ("MSC") MARKET
 
     The Mobile Switching Center ("MSC") market Non-Recurring Engineering
("NRE") Fee, of [                ] dollars ($[      ]) per Mobile Switching
Center ("MSC"), is a one time charge per MSC which will cover the work
associated with MSC network interconnection analysis and coordination,
market-specific Cell/ Face coverage mapping, selective router assignment and
location description assignment; initial pANI data build & validation with
Qualified PSAPs in each market area served by the MSC; delivery of validated
pANIs to appropriate ALI databases; MSC market wireless 9-1-1 test coordination,
as described in Exhibit A. Said NREs will be due upon execution of a
Modification Order, Request Form or such other documentation that accompanies
AMCI's request that SCC initiate the work related to turning up an MSC with the
Services.
 
B. MONTHLY RECURRING FEES ("MRF") FOR SERVICES
 
     The Monthly Recurring Fees ("MRF") for Services are itemized below and are
each charged on a per Subscriber per month basis. MRF shall commence at such
time as Service is deployed to the Qualified PSAP in AMCI's Region which
Qualified PSAP is the first in time to be deployed by AMCI.
 
     The MRF for Services, provided on an exclusive basis by SCC during the term
of this Agreement in the Ameritech Wireline Region, and on a non-exclusive basis
in all other AMCI Regions, and will be billed at a rate of $[      ] per
Subscriber per month. This rate shall be fixed for the term of this Agreement
unless modified pursuant to this Agreement and the following adjustments:
 
          Any time after 12 months from the date on which a particular Qualified
     PSAP, which has requested Phase I E9-1-1 Service, is turned-up and Services
     are deployed by SCC in accordance with the terms of this Agreement, if AMCI
     elects to exercise its option to perform all of the "Transitioned Services"
     described in subparagraph 2.5.1(a) of the Agreement, then only as to those
     particular Qualified PSAPs in those market(s) in which AMCI performs such
     Transitioned Services, the above MRF of $[      ] will be discounted by
     $[       ]; and
 
          Any time after 12 months from the date on which a particular Qualified
     PSAP, which has requested Phase I E9-1-1 Service, is turned-up and Services
     deployed by SCC in accordance with the terms of this
 
                                        7
<PAGE>   10
 
     Agreement, if AMCI elects to exercise its option to perform all of the
     "Transitioned Services" described in subparagraph 2.5.1(b) of the
     Agreement, then only as to those Qualified PSAPs in those market(s) in
     which AMCI performs such Transitioned Services, another discount in the
     amount of $[       ] will be applied to further reduce said MRF.
 
     For those markets in which AMCI does not perform all of the applicable
Transitioned Services, no discount will apply. AMCI may exercise either or both
of such options in any order, regardless of whether done consecutively,
non-consecutively or concurrently.
 
     Unless otherwise mutually agreed by the parties in writing, an increase in
the fees, rates and prices referenced herein, if any, which occur beyond the
initial term of this Agreement will not exceed [               ] of the relevant
fee, rate or price in effect during the immediately-preceding twelve (12) month
period.
 
C. REPORTING
 
     The Parties will cooperate monthly as follows in calculating the number of
Subscribers as follows:
 
          1. Not later than the 15th day of each month, commencing the first
     month that Services have been deployed, and continuing for the duration of
     this Agreement, SCC will provide to AMCI, in an agreed-upon electronic
     format, a list of zip codes falling with a given Qualified PSAP boundary
     for which such Qualified PSAP has deployed Services. Unless otherwise
     modified in connection with a mutually agreed-upon "true-up" process, as
     described in paragraph 3 herein below, said list will only include those
     zip codes in which at least fifty percent (50%) of a given zip code area
     falls within a Qualified PSAP boundary.
 
          2. No later than seven (7) business days after AMCI's receipt of such
     list of zip codes, AMCI will provide to SCC, in an agreed-upon electronic
     format, with the number of Subscribers in each zip code, broken down by
     Qualified PSAP.
 
          3. Recognizing that this method of calculating Subscribers leaves open
     the possibility that AMCI could be under-charged or over-charged in any
     given month and that another method may be appropriate, the Parties will
     work together and will mutually agree upon an acceptable method to
     "true-up" the number of Subscribers and related MRFs on a calendar quarter
     basis. Until such time, the above calculation shall govern the number of
     Subscribers.
 
D. BILLING & PAYMENT
 
     MRF for Services performed in a given month will be invoiced in arrears on
or about the first day of each month commencing the first month following the
date on which Services are first provided. MRF invoices will be payable by AMCI
without interest or penalty not later than thirty (30) days after AMCI's receipt
of said invoice. SCC will prepare invoices broken out by AMCI Market (which may
be modified from time to time by AMCI with reasonable advance written notice to
SCC).
 
     SCC shall not be entitled to reimbursement by AMCI for SCC's costs of
travel or any expense directly related to any non-recurring engineering fees
(NRE).
 
  4.1.2  FAIR MARKET VALUE.
 
     The Parties agree that the price of tangible and intangible assets referred
to in this Agreement fair market value for same. With respect to any other fees,
charges, payments or purchases prospectively negotiated or determined by the
Parties which related to the Project, the same will likewise reflect fair market
value. If the Parties are unable to agree upon a price for same, each shall
select an appraiser knowledgeable in the valuation of the types of items at
issue, and the two appraisers shall attempt to reach agreement on the fair
market value. If the two appraisers are unable to reach agreement, they shall
select a third appraiser who also shall be knowledgeable in the valuation of
such matters. The three appraisers shall then determine the fair market value,
but if they are unable to agree, the fair market value shall be set by the third
appraiser. Each Party shall bear the expense of the appraiser selected by it,
and the Parties shall split the expense of the third appraiser.

  4.1.4  AUDITS.
 
     At its sole expense, SCC shall maintain complete and accurate books and
records with respect to the Project, and said books and records shall be
maintained in accordance with generally accepted accounting principles. Each
Party shall have the right to audit the books and records of the other which
books and records relate specifically to the calculation of the number of
Subscribers and related Monthly Recurring Fees (referred to as "MRF" in Exhibit
B). In addition, AMCI shall have the right to audit the books and records of SCC
which relate to prices charged to AMCI hereunder in connection with AMCI's "Most
Favored Customer" status, or which relate to billing for Fees and Charges
described in this section 4 as well as that which is relevant to SCC's
data-protection and security obligations hereunder. Such audits may be performed
at the premises of the other Party, shall be limited to once per calendar year
and shall only be allowed with not less than fifteen (15) days advance written
notice to the audited Party. Each Party will be responsible for its own costs
related to such audits. "Undisputed" invoices, as defined herein, which are not
adjusted within 12 months of the date of such invoice shall be deemed accepted
by the Parties, regardless of whether such invoice was included in a prior or
subsequent audit.
 
4.2  OTHER CHARGES.
 
     Charges for miscellaneous services not contemplated in Exhibit A or section
4 hereunder, which services do not include Services, SCP Services, Add-On
Services or New Services ("Other Charges"), will be offered to AMCI on a
time-and-materials basis using SCC's then-current rates for same, less AMCI
discounts, if any, that may be applicable. In the event AMCI requests that SCC
provide such services, SCC shall first furnish AMCI with an estimate of the
amount of the Other Charges, which, upon written agreement of the Parties, may
include travel and other related expenses, and specify a reasonable
"not-to-exceed" billable amount. Billings of Other Charges for the requested
services shall not exceed the specified amount without AMCI's prior written
approval. Other Charges shall be billed in arrears, after provision of the
relevant services, and AMCI shall pay Other Charges within thirty (30) days of
the date of invoices related to such services.
 
4.3  DISPUTED INVOICES.
 
     In the event of a disputed invoice, AMCI shall notify SCC within sixty (60)
days of the receipt of any such invoice and identify the nature of the dispute
or inaccuracy. AMCI shall pay any undisputed amounts set forth in said invoice
in accordance with the provisions hereof pertaining to normal payment of
invoices, and both parties shall in good faith investigate and attempt to
resolve the outstanding disputed amount.
 
4.4  TAXES.
 
     Fees and charges payable hereunder shall not include any sales, use,
excise, transaction or other similar taxes levied against or upon the furnishing
or receipt of Service or SCP Services. Further, the amounts payable by AMCI
hereunder are exclusive of all federal, state and local taxes, taxes that are
based on SCC's net or
 
                                        9
<PAGE>   12
 
gross receipts, franchise taxes or other taxes based on SCC's corporate
existence or status, personal property taxes on licensed software and taxes that
may be due in whole or in part because of any failure by SCC or its agents to
file any return or information required by law, rule or regulation. If any sales
or other taxes related to SCC's provision of Services are payable or mandated by
current or prospective application of law, they shall be separately stated on
the monthly invoice to AMCI, and AMCI shall be responsible for paying same in
accordance with the terms and conditions set forth in this section 4 for payment
of invoices. AMCI shall reimburse SCC for any penalties or interest actually
levied upon SCC only if AMCI's acts or omissions solely caused such penalty or
interest to be levied.
 
                     5. LICENSES AND DEVELOPED INFORMATION
 
5.1  LICENSES.
 
     Notwithstanding any conflicting provision herein, nothing in this Agreement
shall be construed to grant AMCI any right, title or interest in or license to
any SCC Furnished Technology, as defined herein below, SCC hardware or software
products used in the provision of Services, New Services, Add-On Services, any
other SCC proprietary information or intellectual property or SCC-owned
Proprietary Rights (defined herein below). Nothing in this Agreement shall be
construed to grant SCC any right, title or interest in AMCI Furnished
Technology, as defined herein below, AMCI proprietary information, intellectual
property, any data being provided to SCC by AMCI for use in the provision of
Services, New Services, Add-On Services or AMCI-owned Proprietary Rights.
Notwithstanding the above, AMCI shall be entitled to quiet enjoyment of the
benefits of the software made available to AMCI hereunder during the Initial
Term and any Renewal Terms.
 
  5.1.1  SOURCE CODE -- ESCROW.
 
     With respect only to that SCC-owned software utilized by SCC in connection
with the provision of the Services, SCC shall arrange to place a copy of the
most recent version of such software, and the related source code and any
documentation, in escrow with an escrow agent selected by SCC. Said source code
shall be in the form of magnetic medium compatible with equipment the same or
similar to that which provides the Services. Pursuant to a written agreement
between SCC and said escrow agent, said agent will be under a duty to release
the Source Code to AMCI only after sufficient evidence has been demonstrated to
said agent that: (a) SCC makes an assignment for the benefit of creditors,
admits in writing its inability to pay debts as they mature, has a trustee or
receiver appointed to manage all or a substantial part of its assets, or
commences or has commenced against it a proceeding under the United States
Bankruptcy Code and such proceeding is acquiesced in or not dismissed within
sixty (60) days; or (b) SCC ceases, for any reason, to do business or to provide
maintenance and support for such software and or Services.
 
     Such software, source code and documentation shall only be released after
said agent has provided SCC not less than thirty (30) days written notice of the
escrow agent's intent to release same to AMCI.
 
     If the software is modified during the term of this Agreement, SCC shall be
responsible for ensuring that an updated copy thereof, and updated source code
and documentation, is deposited with said escrow agent not less than ten (10)
days after SCC's receipt of such modification, or fifteen (15) days after such
modification occurs, whichever is later. The costs related to said escrow
agreement and any release of the source code shall be borne by SCC and AMCI
equally.
 
  5.1.2  LOCATION-BASED SOFTWARE.
 
     SCC agrees to utilize the software of Signal Soft in connection with SCC's
provision of Services and will maintain said software in its most current form
and will provide AMCI with support of the mapping functionality for the
location-based software as described in Exhibit A. At no cost to SCC, AMCI shall
provide SCC with a copy of MAPs Software ("Licensed Software") which AMCI has
licensed from SignalSoft Corp. ("SignalSoft") for use by SCC in its provision of
database management services for AMCI pursuant to the terms of this Agreement.
SCC agrees to abide by the restrictions on disclosure and copying of
                                       10
<PAGE>   13
 
the Licensed Software contained in Section 4 of AMCI's agreement with
SignalSoft, a copy of which Section is attached hereto as Exhibit E, and agrees

     their obligations with respect thereto; and

     extent and for the purposes of such required disclosure, and only if the
     Recipient first notifies the Disclosing Party of the order which permits

     protective order;
 
          (g) is disclosed in response to a valid order of court or other
     governmental body of the United States or any political subdivisions
     thereof, but only to the extent of and for the purpose of such order, and
     only if the Recipient first notifies the Disclosing Party of the order and
     permits the Disclosing Party to seek an appropriate protective order.
 
6.3  OWNERSHIP OF CONFIDENTIAL INFORMATION.
 
     Confidential Information, including permitted copies, shall remain vested
in, and be deemed the property of the Disclosing Party. The Recipient shall,
within twenty (20) days of a written request by the Disclosing Party, return all
Confidential Information (or any designated portion thereof), including all
copies thereof, to the Disclosing Party or if so directed by the Disclosing
Party, destroy such Confidential Information. The Recipient shall also, within

certify in writing that it has satisfied its obligations under this section. If
the Recipient fails to abide by its obligations under this section, the
Disclosing Party shall be entitled to immediate injunctive relief in addition to

THERE ARE NO EXPRESS OR IMPLIED WARRANTIES, INCLUDING THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, REGARDING THE SERVICES
PROVIDED BY SCC HEREUNDER.
 
     If AMCI fails to meet its obligations hereunder, or if AMCI is negligent in
its performance hereunder or willfully commits an act or omission with regard to
the provisions hereof, and such failure, negligence or willful conduct
proximately causes a circumstance where SCC is unable to meet one or more of its
warranty obligations hereunder, then performance by SCC under such warranties
shall be suspended as of the date of such failure, negligence or willful
conduct, as the case may be until cured by AMCI. If the nature of the affected
warranty is such that it can not be cured, then such warranty shall be void.
 
     SCC has all requisite power and authority and all material licenses,
permits and other authorization necessary to own an operate its business and to
perform the obligations imposed upon it hereunder and to provide the Services
and SCP Services;
 
     Any computer software or routing services supplied or delivered hereunder

     SCC warrants that it has no knowledge of any existing software viruses that
would materially impact SCC's performance hereunder. If SCC becomes aware of any
such viruses in its products used in the performance of the Services ordered by
AMCI, it will advise AMCI in writing immediately. If AMCI's performance
hereunder is negatively impacted by SCC's failure to notify AMCI in a timely
fashion of a software virus of which SCC has notice, SCC shall be responsible
for such consequences. Upon learning of a virus in its software, SCC shall use
its best efforts to remedy it as soon as possible.
 
     In the event of any breach of the above warranties, SCC will, at its sole
expense, take appropriate corrective action, including repair or replacement of
the system component not meeting such warranty with respect to hardware or
software and with respect to personnel and business operations, re-performance
of Services or SCP Services or such remedial action as will bring such warranty
into compliance
 
7.2 WARRANTY BY AMCI.
 
     (a) AMCI warrants that it has all requisite power and authority and all

its business and to perform the obligations imposed upon it hereunder;

negatively impacted by AMCI's failure to notify SCC in a reasonably timely
fashion of its knowledge of such viruses, AMCI shall be responsible for such
consequences. Upon learning of such a virus, AMCI shall use its best efforts to
remedy same as soon as possible, at no cost to SCC.

suits and liabilities, whether based in contract or tort (including strict

shall have no relevance, value or binding effect hereon.

of the Services. If implemented, each Party will be responsible for its
respective costs associated with such exchange.

     Neither party shall assign any right or obligation under this Agreement

obligation to escalate the matter shall exist by either Party, in which case,
the Parties are free to pursue any and all remedies available at law or in
equity.
 
11.8 FORCE MAJEURE.
 
     Neither Party shall be liable to the other for any delay or failure to
perform under this Agreement if the delay or failure to perform is without the
fault or negligence of the Party claiming excusable delay and is due to causes
beyond the control of said Party, including, but not limited to acts of God,

local personal income taxes, social security taxes, unemployment and sickness

           4.2 ORGANIZATION AND GOOD STANDING. Seller is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware. Subsidiary is a company duly organized, validly existing and in good
standing under the laws of Australia. Each of Seller and Subsidiary is duly
qualified to do business and is in good standing as a foreign corporation in
each jurisdiction in which such qualification is necessary under applicable law
as a result of the conduct of its business or the ownership or leasing of its
assets and the failure to be so qualified would have a material adverse effect
on such entity or the Business. Seller has the legal right, corporate power and
authority, and all licenses and other permits, required to operate the Business
as now conducted and to own, use and sell the Purchased Assets. Seller has
delivered to, or made available for inspection by, Buyer or its counsel true,
correct and complete copies of (i) Seller's and Subsidiary's charter documents
and all amendments thereto; (ii) Seller's and Subsidiary's Bylaws and all
amendments thereto, duly certified by its corporate secretary; and (iii)
Seller's and Subsidiary's minute and stock books. No actions, proceedings or
transactions have been commenced or undertaken by the Seller which give or would
give rights to any person, other than Buyer, in any of the Purchased Assets or
Purchased Stock or interfere with the consummation of the transactions
contemplated by this Agreement.

           4.3 FINANCIAL STATEMENTS. Seller has delivered to Buyer unaudited
financial statements of Seller and Subsidiary relating to the Business
consisting of (i) an unaudited balance sheet as of June 30, 1997 (the "June
Balance Sheet"), and (ii) an unaudited balance sheet, and a related statement of
operating expenses, as of and for the period ended December 31, 1996, (the
"December 31, 1996 Financial Statements") (the June Balance Sheet and the
December 31, 1996 Financial Statements are collectively referred to herein as
the "Financial Statements"). True, correct and complete copies of the Financial
Statements are attached as Schedule 4.3A hereto. The Financial Statements fairly
present the financial condition of the Business and the results of its
operations as of the relevant dates thereof and for the respective periods
covered thereby, and have been prepared in accordance with generally accepted
accounting principles. Except as set forth in Schedule 4.3B, Schedule 1.2 and
Schedule 4.6 neither Seller nor Subsidiary has any debts, obligations,
liabilities or commitments of any nature relating to the Business, whether due
or to become due, absolute, contingent or otherwise, that, in accordance with
GAAP, are required to be disclosed in a balance sheet or the footnotes thereto,
and are not shown on the June Balance Sheet delivered pursuant hereto, other
than liabilities incurred after June 30, 1997 in the ordinary course of business
and consistent with past practice. Such post-June 30, 1997 liabilities have not
had, and are not expected to have, individually or in the aggregate, a material
adverse effect on the financial condition or results of operations or prospects
of Subsidiary or the Business. As to each liability, debt, obligation or
commitment, fixed or contingent, that is set forth on Schedule 4.3B and is
included in the Assumed Obligations, Seller shall provide the following
information, in writing as an attachment to such Schedule: (i) a summary
description of the liability, debt, obligation or commitment, together with
copies of all relevant documentation relating thereto, the amounts claimed and
any other action or relief sought and, if in connection with a claim, suit or
proceeding, the name of the claimant and all other parties involved therewith
and the identity of the court or agency in which such claim, suit or proceeding
is being prosecuted, and (ii) the best estimate of Seller of the maximum amount,
if any, which is likely to become payable with respect to any contingent
liability. For purposes hereof, if no written estimate is provided, such best
estimate shall be deemed to be zero.

           4.4 ABSENCE OF CERTAIN CHANGES. During the period from June 30, 1997
to the date hereof, there has not been with respect to or affecting Seller,
Subsidiary or the Business: (i) any 

                                       5
<PAGE>   7

amendment, termination or revocation, or any threat known to the Seller of any
amendment, termination, or revocation, of any material contract or agreement to
which Seller or Subsidiary is, or was, a party which relates to Subsidiary or
the Business, or of any license, permit or franchise required for the continued
operation of the Business in substantially the same manner as it has been
conducted since its incorporation; (ii) except for the transactions contemplated
hereby, any sale, transfer, mortgage, pledge or subjection to lien, charge or
encumbrance of any kind, of, on or affecting any of the Purchased Assets, except
sales that have been made in the ordinary course of the Business and consistent
with past practices, and liens for current taxes not yet due and payable; (iii)
other than as contemplated in connection with the transactions contemplated
hereby, any increase in the compensation paid or payable or in the fringe
benefits provided to any employees of the CAD/RMS Division or Subsidiary; (iv)
any damage, destruction or loss, whether or not covered by insurance, of any of
the Purchased Assets; (v) the incurrence of any indebtedness, either for
borrowed money or in connection with any purchase of assets, or otherwise on
behalf of the Business, that is not reflected in the June 30, 1997 balance sheet
and individually or in the aggregate involves more than $5,000; (vi) any
purchase or lease, or commitment for the purchase or lease, of equipment,
machinery, leasehold improvements or other capital items for use in the Business
not disclosed in the June 30, 1997 Financial Statements which involves amounts
exceeding $5,000 individually or $10,000 in the aggregate or which is in excess
of or represents a departure from the normal, ordinary and usual requirements of
the Business; (vii) the execution by Seller or Subsidiary of any agreement or
contract relating to the Business that obligates Seller or Subsidiary to pay
more than $10,000 per year or which is materially disadvantageous to Seller,
Subsidiary or the Business; or (viii) the occurrence subsequent to June 30, 1997
of any other event or circumstance which, could reasonably be expected to
materially and adversely affect the Subsidiary, any of the Purchased Assets, the
Business, or the ability of the Seller to consummate the transactions
contemplated hereby.

           4.5 THE PURCHASED ASSETS.

               (a) TITLE TO AND ADEQUACY OF PURCHASED ASSETS. Except as
disclosed on Schedule 4.5 hereto, Seller has, and at the Closing Seller will
convey and transfer to Buyer, good, complete and marketable title to all of the
Purchased Assets, free and clear of all mortgages, liens, security interests,
encumbrances, pledges, leases, equities, claims, charges, restrictions,
conditions, conditional sale contracts and any other adverse interests. Except
as set forth on Schedule 4.5, all of the Purchased Assets are in the exclusive
possession and control of Seller and Seller has the unencumbered right to use
and sell to Buyer all of the Purchased Assets without interference from others.
The Purchased Assets constitute all the assets, properties, rights, privileges
and interests necessary for Buyer to own and operate the Business substantially
in the same manner as it has been conducted by Seller during the period
immediately preceding the execution of this Agreement.

               (b) TANGIBLE ASSETS. Schedule 1.1(b) is a list of all of the
Tangible Assets used in the Business, other than any Tangible Asset the
replacement cost of which would be less than $1,000.00 and which is not of
material importance to Seller's operations. The Tangible Assets are in good
working order and condition, ordinary wear and tear excepted, have been
maintained in accordance with generally accepted industry standards, are
suitable for the uses for which they are being utilized in the Business and
comply with all requirements under applicable laws, regulations and licenses
which govern the use and operation thereof.


                                       6
<PAGE>   8

               (c) INTANGIBLE PROPERTY RIGHTS. The Intangible Property Rights
are the only material intangible property used by Seller in the Business, and
from and after the Closing Date, Buyer shall have the right to use all of the
Intangible Property Rights in the Business consistent with Seller's use of the
Intangible Property Rights in the Business. Seller owns, or holds adequate
licenses, or other rights to use, all of the Intangible Property Rights, such
use does not conflict with, infringe on or otherwise violate any rights of any
other person. Except as disclosed in Schedule 4.5, all of such licenses and
rights are transferable to Buyer without cost or liability to Buyer and will be
included in the Purchased Assets being sold to Buyer hereunder. Except as set
forth on Schedule 4.5, Seller has not granted, transferred or assigned any
right, license or interest in any of its Intangible Property Rights. In no
instance has the eligibility of any copyright to any material property included
in the Intangible Property Rights been forfeited to the public domain by
omission of any required notice or any other action. All personnel, including
employees, agents, consultants and contractors, who have contributed to or
participated in the conception and development of any of the Intangible Property
Rights on behalf of Seller either (i) in the case of any copyright, have been
party to a "work-for-hire" arrangement or agreement with Seller, in accordance
with applicable federal and state law, that has accorded Seller full, effective,
exclusive and original ownership of all United States copyrights thereby arising
or (ii) shall, prior to the Closing, have executed appropriate instruments of
assignment in favor of Seller as assignee that convey to Seller full, effective
and exclusive ownership of all Intangible Property Rights thereby arising.
Except as set forth in Schedule 4.5, Seller has not infringed, is not now
infringing and has not received notice of any infringement, on any patent, trade
name, trademark, service mark, copyright, trade secret, trade dress, design,
invention, technology, know-how, process or other proprietary right belonging to
any other person, firm or corporation, which infringement would have an adverse
effect on any of the Purchased Assets or the Business. To the best of Seller's
knowledge, there is no infringement by any other person of any Intangible
Property Right.

               (d) LEASES. Schedule 4.5(d) is a list of each of the facilities
or real properties used in the Business. Schedule 4.5(d) also contains a list of
all leases under which Seller possesses or uses personal property in connection
with the conduct or operation of the Business. The personal property leases set
forth in Schedule 4.5(d) are sometimes collectively referred to as the "Personal
Property Leases." True, correct and complete copies of the real property leases
set forth in Schedule 4.5(d), the Real Property Leases and Personal Property
Leases (collectively, the "Leases") have been delivered to Buyer. Seller is not,
and as of the Closing Date will not be, in default, and no facts or
circumstances have occurred, or on or prior to the Closing will occur, which
through the passage of time or the giving of notice, or both, would constitute a
default, under any of the Leases. Subject to any consents required therefor, the
assignment of any of the Real Property Leases and the personal property leases
set forth in Schedule 4.5(d) shall not adversely affect Buyer's quiet enjoyment
and use, without disturbance, of all real and personal properties and assets
that are the subject of such leases. None of the Leases contains any provisions
which, after the Closing Date, would (i) hinder or prevent Buyer from continuing
to use any of the properties or assets which are the subject of the personal
property leases set forth in Schedule 4.5(d) in the manner in which they are
currently used or (ii) impose any additional costs (other than scheduled rental
increases) or additional burdensome requirements as a condition to their
continued use. Except as otherwise set forth in Schedule 4.5(d) hereto, none of
the Purchased Assets are held under, or used by Seller in connection with the
Business pursuant to, any lease or conditional sales contract.

               (e) ACCOUNTS RECEIVABLE. Attached hereto as Schedule 4.5(e) are
(i) an accurate list of all accounts and notes


                                       7

<PAGE>   9

receivable of Seller, including any accounts or notes receivable not reflected
in the June 30, 1997 balance sheet, and (ii) an aging of all such accounts and
notes receivable showing amounts due in 30-day aging categories. All such
accounts and notes receivable on such listing arose from, and all accounts and
notes receivable of Seller created between June 30, 1997 and the Closing will
have arisen from, the sale of Seller's products or the provision of services by
Seller in the ordinary course of business. The Seller has not received any
notice or knows of any counterclaim or set-off with respect to any such accounts
or notes receivable, or any facts or circumstances that would be the basis for
any such counterclaim or set-off, which is not reflected or taken into account
in the contractual allowance or bad debt reserves set forth in the June 30, 1997
balance sheet.

           4.6 CONTRACTS, AGREEMENTS AND COMMITMENTS. Schedule 4.6 hereto
contains an accurate and complete list of all contracts, agreements, leases,
licenses and instruments to which Seller or Subsidiary is a party or is bound or
which relate to or affect any of the Purchased Assets or the Business. Schedule
4.6 includes, without limitation, all contracts and agreements and all leases,
licenses and instruments, which (i) grant a security interest or permit or
provide for the imposition of any lien, mortgage, security interest or other
encumbrance on, or provide for the disposition of, any of the Purchased Assets;
(ii) require the consent of any third party to the consummation by Seller of the
transactions contemplated by this Agreement, as noted on such schedule; (iii)
would restrict the use or disposition by Buyer after the Closing of any of the
Purchased Assets; or (iv) pertain to the sale or lease of CAD/RMS Products to
third parties (including the status of the contract, the contract price, the
amount collected to date and whether the CAD/RMS Product has been accepted.
True, correct and complete copies of all items so listed in Schedule 4.6 have
been furnished to Buyer. Each of such contracts, agreements, leases, licenses
and instruments so listed, or required to be so listed, in Schedule 4.6 is a
valid and binding obligation of Seller and/or Subsidiary and the other parties
thereto, enforceable in accordance with its terms, except as may be affected by
bankruptcy, insolvency, moratorium or similar laws affecting creditors' rights
generally and general principles of equity relating to the availability of
equitable remedies. Except as otherwise set forth in Schedule 4.6 hereto, there
have not been any defaults by Seller or Subsidiary or, to the best knowledge of
the Seller, defaults or any claims of default or claims of nonenforceability by
the other party or parties which, individually or in the aggregate, would have a
material adverse effect on Subsidiary, the Business or any of the Purchased
Assets, and there are no facts or conditions that have occurred or that are
anticipated to occur which, through the passage of time or the giving of notice,
or both, would constitute a default by Seller, or to the best knowledge of the
Seller, by the other party or parties, under any of such contracts, agreements,
leases, licenses and instruments or would cause a creation of a lien, security
interest or encumbrance upon any of the Purchased Assets or otherwise materially
and adversely affect Subsidiary, any of the Purchased Assets or the Business.

           4.7 LABOR AND EMPLOYMENT AGREEMENTS; FRINGE BENEFIT PLANS.

               (a) Schedule 4.7 sets forth the name of each director and officer
of Subsidiary and of each employee of Seller or Subsidiary who is engaged in the
Business, together with a description of all compensation and benefits that are
payable to such individuals as a result of their employment by or association
with Seller or Subsidiary. Schedule 4.7 includes a description of all employment
or personnel policies of Seller relating to vacation or other employee benefits.

               (b) Schedule 4.7 hereto contains a list of any collective
bargaining or other labor, employment, deferred compensation, bonus, retainer,
consulting, or incentive agreement, plan or contract, and all written or other
personnel policies, of Seller or Subsidiary or to 


                                       8
<PAGE>   10

which Seller or Subsidiary is subject or bound. True, correct and complete
copies of any such agreements, plans, contracts and policies listed in Schedule
4.7 hereto have been furnished to Buyer. Except to the extent set forth in
Schedule 4.7, (i) there has been no strike or other work stoppage by, nor to the
best knowledge of Seller has there been any union organizing activity among, any
of the employees of Seller or Subsidiary; (ii) Seller and Subsidiary are in
compliance in all material respects with all applicable laws respecting
employment and employment practices, terms and conditions of employment and
wages and hours, and is not engaged in any unfair labor practice; and (iii)
there is no unfair labor practice complaint pending or, to the best knowledge of
the Seller, threatened against Seller or Subsidiary, nor, to the best knowledge
of the Seller, is there any factual basis for any such complaint.

               (c) Schedule 4.7 hereto also contains a complete list of Seller's
and Subsidiary's Employee Plans. True, correct and complete copies or
descriptions of such Employee Plans have been delivered to Buyer. For purposes
of this Section 4.7, the term "Employee Plan" includes all past or present
plans, programs, agreements, arrangements, and methods of contribution or
compensation (including all amendments to and components of the same, such as a
trust with respect to a plan) maintained by Seller or Subsidiary or to which
Seller or Subsidiary has an obligation to contribute which provide any
remuneration or benefits, other than current cash compensation, to any current
or former employee of Seller or Subsidiary or to any other person who provides
services to Seller or Subsidiary. The term Employee Plan includes, but is not
limited to, pension, retirement, profit sharing, stock option, stock bonus, and
nonqualified deferred compensation plans and includes any Employee Plan that is
a multiemployer plan as defined in Section 3(37) of ERISA. The term Employee
Plan also includes, but is not limited to, disability, medical, dental, health
insurance, life insurance, incentive plans, vacation benefits, and fringe
benefits. Except as set forth on Schedule 4.7, none of the Employee Plans are
subject to the Employee Retirement Income Security Act of 1974, as amended
("ERISA") or are qualified under the Code. Except as set forth in Schedule 4.7,
all Employee Plans are now, and have always been, established, maintained and
operated in all material respect in accordance with all applicable laws
(including, but not limited to, ERISA and the Code) and all regulations and
governing guidelines promulgated thereunder and in accordance with their plan
documents. Each funded Employee Plan providing for payment of deferred
compensation (a "Qualified Plan") is and always has been qualified under Section
401 of the Code. The Internal Revenue Service has issued one or more
determination letters with respect to each Qualified Plan stating that each such
Qualified Plan is qualified under Section 401 of the Code and each trust
maintained in connection with each such Qualified Plan has been and is exempt
under Section 501 of the Code. Except as set forth in Schedule 4.7, there is no
unfunded liability for vested or nonvested benefits under any funded Employee
Plan, and all contributions required to be made to or with respect to each
Employee Plan have been completely and timely paid. All reports, forms and other
documents required to be filed with any governmental entity with respect to any
Employee Plan have been timely filed and, to the best knowledge of the Seller,
are accurate. There have been no filings with respect to any Employee Plan with
the Pension Benefit Guaranty Corporation ("PBGC"). No liability to the PBGC has
been incurred or is expected with respect to any Employee Plan except for
insurance premiums, and all insurance premiums incurred or accrued up to and
including the Closing Date have been or will be timely paid by Seller. No amount
is, and as of the Closing Date no amount will be, due or owing from Seller or
Subsidiary to any "multiemployer plan" (as defined in Section 3(37) of ERISA) on
account of any withdrawal therefrom. There has been no event or condition, nor
is any event or condition expected, that would present a risk of termination of
any Employee Plan, or which would constitute a "reportable event" within the
meaning of Section 4043 of ERISA and the regulations and 


                                       9
<PAGE>   11

interpretations thereunder. There has been no merger, consolidation, or transfer
of assets or liabilities (including, but not limited to, a split-up or
split-off) with respect to any Employee Plan. There is and there has been no
actual or, to the best knowledge of the Seller, anticipated, threatened or
expected litigation or arbitration concerning or involving any Employee Plan. No
complaints to or by any governmental entity have been filed or, to the best
knowledge of the Seller, have been threatened or are expected with respect to
any Employee Plan. No Employee Plan or any other person has any liability to any
plan participant, beneficiary or other person under any provision of ERISA, the
Code or any other applicable law by reason of any action or failure to act in
connection with any Employee Plan. There has been no prohibited transaction as
described in Section 406 of ERISA and Section 4975 of the Code with respect to
any Employee Plan. No Employee Plan provides medical benefits to one or more
former employees (including retirees), other than benefits required to be
provided under Section 4980B of the Code. There is no contract, agreement or
benefit arrangement covering any employee of Seller or Subsidiary, the payments
under which, individually or collectively, would constitute an "excess parachute
payment" under Section 280G of the Code.

           4.8 CONFLICTS. Except as described on Schedule 4.6 hereto, neither
the execution and delivery of, nor the consummation of the transactions
contemplated by, this Agreement or the Related Agreements to which Seller is a
party will or could result in any of the following: (i) a default or an event
that, with notice or lapse of time, or both, would be a default, breach or
violation of the respective charter, bylaws or other governing instruments of
Seller or Subsidiary, or any contract, lease, license, franchise, promissory
note, conditional sales contract, commitment, indenture, mortgage, deed of
trust, security or pledge agreement, or other agreement, instrument or
arrangement to which the Seller or Subsidiary is a party or is bound which
relates to the Business or which affects any of the Purchased Assets; (ii) the
termination of any contract, lease, agreement, or commitment, or the
acceleration of the maturity of any indebtedness or other obligation of the
Seller or Subsidiary; (iii) the creation or imposition of any lien, charge or
encumbrance on any of the respective assets or properties of the Seller or
Subsidiary, including any of the Purchased Assets; (iv) a violation or breach of
any writ, injunction or decree of any court or governmental instrumentality to
which the Seller or Subsidiary is a party or is bound or which affects any of
their respective properties or any of the Purchased Assets or the Business; (v)
a loss or adverse modification of any license, franchise, permit, other
authorization or right (contractual or other) to operate, granted to or
otherwise held by Seller or Subsidiary or used in the Business, which would have
a material adverse effect on the Business or Buyer; or (vi) the cessation or
termination of any other business relationship or arrangement between Seller or
Subsidiary and any third party that is material to the Business, or its
operating results, condition (financial or other) or prospects or any of the
Purchased Assets. Except as set forth in Schedule 4.6 hereto, the Seller does
not know of any business relationship or arrangement between it or Subsidiary
and any third party (governmental or other) that is material to the Business,
its operating results, condition or prospects and that will cease or is likely
to be terminated as a result of the consummation of the transactions
contemplated by this Agreement.

           4.9 INSURANCE. Schedule 4.9 contains an accurate list (including
liability limits, deductibles and coverage exclusions) of all policies of
insurance maintained by or on behalf of Seller or Subsidiary in connection with
the Business as protection for the Purchased Assets and the Business. Except as
set forth in Schedule 4.9 hereto, all of such policies are now in full force and
effect and policies covering the same risks and in substantially the same
amounts have been in full force and effect continuously since inception. Neither
Seller nor Subsidiary has received any notice 


                                       10
<PAGE>   12

of cancellation or material amendment of any such policies; no coverage
thereunder is being disputed; and all material claims thereunder have been filed
in a timely fashion.

           4.10 TAXES AND TAX RETURNS. Each of Seller and Subsidiary has duly
filed all tax reports and returns which are required by law to be filed by it
and has duly paid all foreign, federal, state and local taxes due or claimed to
be due from such authorities, and there are no assessments or claims for payment
of taxes now pending or, to the best knowledge of the Seller, threatened, nor is
any audit of Seller's or Subsidiary's records presently being made by any taxing
authority. Each of Seller and Subsidiary has properly withheld and paid, or
accrued for payment when due, to appropriate state and/or federal authorities,
all amounts required to be withheld from its employees' wages, salaries and
other compensation and has also paid all employment taxes as required under
applicable laws.

           4.11 COMPLIANCE WITH LAW/PERMITS.

               (a) Seller and Subsidiary are in compliance with all, and are not
in violation of any, law, ordinance, order, decree, rule or regulation of any
governmental agency or authority, the violation of or noncompliance with which
could reasonably be expected to have a material adverse effect on the Business
or any of the Purchased Assets. Without limiting the generality of this Section
4.11(a), there are no unresolved (i) proceedings or investigations instituted
or, to the best knowledge of the Seller, threatened, by any such governmental
authorities against Seller or Subsidiary relating to the Business, or (ii)
citations issued or, to the best knowledge of the Seller, threatened against
Seller, Subsidiary or the Business by any governmental authorities, or (iii)
other notices of deficiency or charges of violation brought or, to the best
knowledge of the Seller, threatened against Seller, Subsidiary or the Business,
including under any federal or state regulation or otherwise, which could
reasonably be expected to have, individually or in the aggregate, a material
adverse effect on the Business or any of the Purchased Assets, or interfere with
the maintenance, or the transfer or reissuance to Buyer, of the permits,
licenses, franchises, certificates, authorizations or any right to operate held
by Seller or Subsidiary; and, to the best knowledge of Seller, there are no
facts or circumstances upon which any such proceedings, investigations,
citations, notices, disallowances or charges may be instituted, issued or
brought hereafter.

               (b) Schedule 4.11(b) contains a true, correct and complete list
of all governmental licenses, permits, authorizations, franchises, or
certificates or rights (contractual or other) to operate the Business, that are
held by Seller or Subsidiary (collectively, "Licenses and Permits"). Such
Licenses and Permits are the only licenses, permits, authorizations, franchises,
certificates and rights to operate required for operation of the Business, as it
has been conducted since its inception, and all of such Licenses and Permits are
in full force and effect at the date hereof and will be as of the Closing. The
Seller has provided Buyer with true, correct and complete copies of each License
and Permit listed in Schedule 4.11(b). Seller and Subsidiary are in compliance
in all material respects with all conditions or requirements imposed by or in
connection with such Licenses and Permits and with respect to its use of the
Purchased Assets and operation of the Business, and neither Seller nor
Subsidiary has received any notice, nor does Seller have any knowledge or reason
to believe, that any governmental authority intends to cancel, terminate or
materially modify any of such Licenses or Permits or that valid grounds for any
such cancellation, termination or material modification currently exist, except
that, by reason of change of ownership of the Business, certain 


                                       11
<PAGE>   13

of the Licenses and Permits listed in Schedule 9.1 will have to be transferred
or reissued to Buyer, and certain of such Licenses and Permits will have to be
reapplied for by Buyer.

           4.12 LITIGATION AND PROCEEDINGS. There is neither (a) any action,
suit, proceeding or investigation, nor (b) any counter or cross-claim in an
action brought by or on behalf of the Seller or Subsidiary, whether at law or in
equity, or before or by any governmental department, commission, board, bureau,
agency or instrumentality, domestic or foreign, or before any arbitrator of any
kind, that is pending or, to the best knowledge of the Seller, threatened,
against Seller or Subsidiary, which (i) could reasonably be expected to affect
adversely Seller's ability to perform its obligations under this Agreement or
the Related Agreements or complete any of the transactions contemplated hereby
or thereby, or (ii) involves the reasonable possibility of any judgment or
liability, or which may become a claim, against Buyer, the Business, the
Purchased Stock or any of the Purchased Assets prior to or subsequent to the
Closing Date. Neither Seller nor Subsidiary is subject to any judgment, order,
writ, injunction, decree or award of any court, arbitrator or governmental
department, commission, board, bureau, agency or instrumentality having
jurisdiction over Seller, any of its assets, Subsidiary or the Business, which
may reasonably be expected to affect the Business.

           4.13 CERTAIN TRANSACTIONS. Except as set forth in Schedule 4.13 ,
there are no existing or pending transactions, nor are there any agreements or
understandings, with any shareholders, officers, directors, or employees of
Seller or Subsidiary, or any person or entity affiliated with any of them
(collectively, "Affiliates"), relating to, arising from or affecting the
Business, or any of the Purchased Assets, including, without limitation, any
transactions, arrangements or understandings relating to the purchase or sale of
goods or services, the lending of monies, or the sale, lease or use of any of
the Purchased Assets, with or without adequate compensation, in any amount
whatsoever. Except as set forth in Schedule 4.13 , no existing or former
shareholder, director, officer or employee of Seller or Subsidiary has any
claims against or disputes with Seller which could result in the imposition of
any liability or judgment against the Business or any of the Purchased Assets.

           4.14 ENVIRONMENTAL AND SAFETY MATTERS. Seller and Subsidiary have
complied with, and the operation of the Business and the use of the Purchased

employment contract, patent disclosure agreement or any other contract or
agreement relating to the relationship 


                                       15

of such persons is obligated; provided that, solely as the foregoing
representation relates to any agreement between an employee and any party other
than Seller, such representation is limited to Seller's best knowledge.

           7.7 TAXES. Seller shall pay all taxes (other than income taxes of

or operations, whether prior to or after the Closing Date, and (ii) the
consummation of the transactions contemplated hereby, including, without
limitation, all sales, use or similar taxes, if any, that may arise from or be
assessed by reason of the sale of the Purchased Assets by Seller to Buyer. If
any taxes required under this Section 7.7 to be borne by Seller are assessed
against Buyer, Buyer shall notify Seller in writing promptly thereafter and
Seller shall be entitled to contest, in good faith, such assessment or charge.
Notwithstanding the foregoing, Buyer may, but shall not be obligated to, pay any
such taxes assessed against it but payable by Seller pursuant hereto, if Buyer's
failure to do so, in the reasonable judgment of Buyer, could result in the
imposition of a lien or attachment on any of the Purchased Assets or any other
assets of Buyer or would constitute a violation of any agreement to which Buyer
is subject, or if Seller fails to contest such assessment or charge in good
faith. In the event Buyer 


                                       21

due in respect of such receivables in 30-day aging categories up to 180 days.

               (a) Seller (in the case of indemnification obligations of the

"Indemnifying Party") hereby agrees that it will indemnify, hold harmless and
defend Buyer and its directors, officers, shareholders, employees, agents and
successors and assigns (in the case of indemnification obligations of Seller,
such persons shall hereinafter be referred to collectively in this Section 13 as
the "Indemnified Parties") from and against any and all Liabilities (as
hereinafter defined) that arise from or are in connection with: (i) any facts,

breach of or inaccuracy in any of the representations or warranties of Seller
contained in this Agreement or in any Exhibits or Schedules hereto or any

                                       27
<PAGE>   29

               (b) Buyer (in the case of indemnification obligations of Buyer,
Buyer shall hereinafter be referred to in this Section 13 as the "Indemnifying
Party") hereby agrees that it will indemnify, hold harmless and defend the
Seller and its directors, officers, shareholders, employees, agents and
successors and assigns (in the case of indemnification obligations of Buyer,
such persons shall hereinafter be referred to collectively in this Section 13 as
the "Indemnified Parties") from and against any and all Liabilities that arise
from or are in connection with: (i) any facts, circumstances or events, the
existence or happening of which constitutes a breach of or inaccuracy in any of
the representations or warranties of Buyer contained in this Agreement or in any
Exhibits or Schedules hereto or any certificates or other documents delivered
hereunder by or on behalf of Buyer; or (ii) any breach or default by Buyer of
any of its covenants or agreements contained in this Agreement, including its
agreement to assume and perform the Assumed Obligations. The liability of the
Buyer to the Indemnified Parties pursuant to this Section 13(b), other than
liability arising out of Buyer's failure to perform the Assumed Obligations
(which shall be limited to the amounts set forth on Schedule 1.3 plus any legal
fees and expenses payable pursuant to subsection (d) below) shall be limited, in
the aggregate, to $100,000.

               (c) "Liabilities," as used in this Agreement, shall mean: (i)
demands, claims, actions, suits, and legal or other proceedings brought against
any "Indemnified Party" (as hereinafter defined), and any judgments rendered
therein or settlements thereof, and (ii) all liabilities, damages, losses,
taxes, costs and expenses, including, without limitation, reasonable attorneys'
fees, incurred by any Indemnified Party, whether or not they have arisen from or
were incurred in or as a result of any demand, claim, action, suit, assessment
or other proceeding or any settlement or judgment, and whether sustained before
or after the Closing Date.

               (d) No claim for indemnification under this Section 13 may be
made by an Indemnified Party (i) until the aggregate amount of such claims
exceeds $25,000, or (ii) more than eighteen (18) months after the Closing Date;
provided, that any claim by an Indemnified Party for indemnification relating to
any taxes or tax returns or reports may be made at any time within the statute
of limitations relating to such taxes or tax returns or reports. To be
effective, any claim for indemnification under this Section 13 by an Indemnified
Party must be made by a written notice (a "Notice of Claim") to the Indemnifying
Party, given in accordance with the provisions of Section 16 hereof, accompanied
by documentation supporting the claim; provided, however, that if the
Indemnified Party has made such claim prior to such expiration date, such
Indemnified Party shall be entitled to recover the full amount of the
Liabilities incurred by it even if that amount is not finally determined until
after such expiration date. In the event of the assertion, in writing, of a
third-party claim or dispute which, if adversely determined would entitle an
Indemnified Party to indemnification hereunder, the Indemnified Party shall
promptly notify the Indemnifying Party thereof in writing. The Indemnifying
Party may elect, by written notice to the Indemnified Party, to assume and
direct, at their sole expense, the defense of any such third-party claim, and
may, at their sole expense, retain counsel in connection therewith, provided
that such counsel is reasonably acceptable to the Indemnified Party. After the
assumption of such defense by the Indemnifying Party with counsel reasonably
acceptable to the Indemnified Party, and for so long as the Indemnifying Party
conduct such defense on a diligent and timely basis, the Indemnifying Party
shall not be responsible for the payment of legal fees incurred thereafter by
the Indemnified Party (who may, however, continue to participate in the defense
thereof with separate counsel); provided, that, the Indemnifying Party shall be
responsible for paying the fees and expenses of one separate counsel for the
Indemnified Party if the Indemnifying Party and the Indemnified Party have
conflicting positions with respect to such third-party claim or dispute or if
the Indemnifying Party, on the one hand, or the 


                                       28
<PAGE>   30

Indemnified Party, on the other hand, have defenses not available to the other.
If the Indemnifying Party fail to and until the Indemnifying Party undertake the
defense of any such third-party claim or dispute, or if the Indemnifying Party
discontinue the diligent and timely conduct thereof, the Indemnified Party may
undertake such defense and the Indemnifying Party shall be responsible for
reimbursing the Indemnified Party for its legal fees and expenses as and when
incurred by the Indemnified Party. No Indemnifying Party hereto may settle or
compromise any such third-party claim or dispute without the prior written
consent of the Indemnified Parties hereto, which consent shall not be
unreasonably withheld.

               (e) Upon receipt of a Notice of Claim, the Indemnifying Party
shall have fifteen (15) calendar days to contest their indemnification
obligation with respect to such claim, or the amount thereof, by written notice
to the Indemnified Party (a "Contest Notice"); provided, however, that if, at
the time a Notice of Claim is submitted to the Indemnifying Party the amount of
the Liability in respect thereof has not yet been determined, such fifteen (15)
day period shall not commence until a further written notice (a "Notice of
Liability") has been sent or delivered by the Indemnified Party to the
Indemnifying Party setting forth the amount of the Liability incurred by the
Indemnified Party that was the subject of the earlier Notice of Claim. Such
Contest Notice shall specify the reasons or bases for the objection of the
Indemnifying Party to the claim, and if the objection relates to the amount of
the Liability asserted, the amount, if any, which the Indemnifying Party believe
is due the Indemnified Party. If no such Contest Notice is given with such
15-day period, the obligation of the Indemnifying Party to pay to the
Indemnified Party the amount of the Liability set forth in the Notice of Claim,
or subsequent Notice of Liability, shall be deemed established and accepted by
the Indemnifying Party. If, on the other hand, the Indemnifying Party contest a
Notice of Claim or Notice of Liability (as the case may be) within such 15-day
period, the Indemnified Party and the Indemnifying Party shall thereafter
attempt in good faith to resolve their dispute by agreement. If they are unable
to so resolve their dispute within the immediately succeeding thirty (30) days,
such dispute shall be resolved by binding arbitration in Los Angeles County,
California, as provided in Section 17(i) below. The award of the arbitrator
shall be final and binding on the parties and may be enforced in any court of
competent jurisdiction. Upon final determination of the amount of the Liability
that is the subject of an indemnification claim (whether such determination is
the result of the Indemnifying Party's acceptance of, or failure to contest, a
Notice of Claim or Notice of Liability, or of a resolution of any dispute with
respect thereto by agreement of the parties or binding arbitration), such amount
shall be payable, in cash by the Indemnifying Party to the Indemnified Party who
have been determined to be entitled thereto within five (5) days of such final
determination of the amount of the Liability due by the Indemnifying Party. Any
amount that becomes due hereunder and is not paid when due shall bear interest
at the maximum legal rate per annum from the date due until paid.

        14. CONFIDENTIALITY. Each party acknowledges that it may have access to
various items of proprietary and confidential information of the other in the
course of investigations and negotiations prior to Closing. Except as otherwise
provided in Section 6.3 above, each party agrees that any such confidential
information received from the other party shall be kept confidential and shall
not be used for any purpose other than to facilitate the arrangement of
financing for and the consummation of the transactions contemplated herein.
Confidential information shall include any business or other information which
is specifically marked by the party claiming confidentiality as being
confidential, unless such information (i) is already public knowledge, (ii)
becomes public knowledge through no fault, action or inaction of the receiving
party, or (iii) was known by the receiving party, or any of its directors,
officers, employees, representatives, agents or advisors prior to 


                                       29
<PAGE>   31

the disclosure of such information by the disclosing party to the receiving
party. No party hereto, nor its respective officers, directors, employees,
accountants, attorneys, or agents shall intentionally disclose the existence or
nature of, or any of the terms and conditions relating to, the transaction
referred to herein, to any third person; provided, however, that such
information may be disclosed in applications or requests required to be made to
obtain any Licenses and Permits, approvals or consents needed to consummate the
transactions contemplated herein or in any Securities Filings. 

        15. EXPENSES AND BROKER'S FEES.

           15.1 EXPENSES/PRORATIONS. Each of the parties shall pay all costs and
expenses incurred or to be incurred by it in connection with the negotiation,
preparation, execution, delivery and performance of its respective obligations

                            NON-COMPETITION AGREEMENT


         THIS NON-COMPETITION AGREEMENT (the "Agreement") is made this 18th day
of July, 1997, by and between SCC COMMUNICATIONS CORP., a Delaware corporation
(the "Seller'), and PRINTRAK INTERNATIONAL INC., a Delaware corporation (the
'Buyer"), with reference to the following:

         A. The Seller develops and markets computer-aided dispatch and records
management software and related software directly to public safety agencies
within all of the states of the United States of America and the District of
Columbia (the "Business").

         B. Buyer and Seller have entered into an Asset Purchase Agreement dated
as of July 18, 1997 (the "Agreement"), pursuant to which Seller will sell to
Buyer all of the assets of the Business.

         C. It is a condition precedent to the obligations of Buyer under the
Agreement that Seller enter into a Non-Competition Agreement in the form of this
Agreement with the Buyer, including the covenant not to compete contained
herein; and Seller understands and acknowledges that this Agreement is a
material inducement to Buyer upon which it is relying in consummating the
transactions contemplated by the Agreement.

         NOW, THEREFORE, in consideration of the mutual covenants, warranties
and representations contained herein, the parties hereby agree as follows:

         1. The Seller covenants, that for a period of three (3) consecutive
years commencing on the date hereof, the Seller shall not directly, or
indirectly through one or more other persons or entities, engage in, or have any
financial or other interests in or provide assistance to any person, firm,
corporation or business that engages in, any activity which is the same as or
competitive with the Business, in, from, at or into (a) any of the states of the
United States of America or the District of Columbia or (b) any of the
countries, territories or areas of the world. Notwithstanding the foregoing,
nothing contained in this Agreement shall prevent or otherwise limit the Seller
from holding, for investment purposes only, no more than one percent (1%) of any
class of equity securities of a company engaged in activities that are
competitive with the Business if such class of equity securities is traded on a
national securities exchange or on the NASDAQ National Market System.


         2. The Seller agrees not to solicit any of the employees of the Buyer
at any time during the Seller's employment with the Buyer, and for a period of
one (1) year following the termination thereof.

         3. The Seller covenants that neither the Seller, nor any employee,
officer, director or agent of the Seller, shall use for his, her or their
benefit, or disclose, communicate or divulge to, or use for the direct or
indirect benefit of any person, firm, association or company, other than the





<PAGE>   40




Buyer, any confidential information regarding the business methods, business
policies, procedures, techniques, trade secrets, software, products, customer
lists or other knowledge or processes used or developed, prior to the Closing,
by the Seller, or other information concerning the Business of which the Buyer
or the Seller became aware prior to the Closing. The foregoing restrictions
shall not apply to (i) information which is or becomes, other than as a result
of a breach of this Agreement, generally available to the public, or (ii) the
disclosure of information required pursuant to a subpoena or other legal
process; provided that the party required to disclose such information shall
notify the Buyer, in writing, of the receipt of any such subpoena or other legal
process requiring such disclosure immediately after receipt thereof and the
Buyer shall have a reasonable opportunity to quash such subpoena or other legal
process prior to any disclosure by the Seller, or (iii) information used in
Seller's NDSC business so long as such business does not compete with the
Business.

         4. The Seller acknowledges that the restrictions contained in
Paragraphs 1, 2 and 3, in view of the nature of the Business and the involvement
of such Seller in the Business, are reasonable and necessary in order to protect
the legitimate interests of the Buyer, and that any violation thereof would
result in irreparable injuries to the Buyer. Therefore, the Seller acknowledges
and agrees that, in the event of a violation by the Seller, of any of the
restrictions contained in Paragraphs 1, 2 or 3 above, the Buyer shall be
entitled to seek and obtain from any court of competent jurisdiction (and
without having to join any other party in such action) temporary, preliminary
and permanent injunctive relief, in addition to any other rights or remedies to
which it or they may be entitled and Seller hereby consents to the issuance of
such injunction or grant of such specific performance. In any action or
proceeding to enforce the provisions of this Agreement, Seller expressly waives
the defense that a remedy of damages will be adequate for a breach of Seller's
duties under this Agreement.

         5. It is expressly agreed by the Seller that if, in any judicial

                                    EXHIBIT F

                    FORM OF OPINION OF COUNSEL TO THE SELLER

Matters to be covered in the Legal Opinion to be delivered by Counsel to the
Seller:

         1. Seller is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware. Seller is not required to be
qualified as a foreign corporation in any other state in which the failure to be
so qualified would have a material adverse effect on Seller. Seller has the
corporate power and authority to own and sell its properties and assets, to
carry on its business as presently conducted, and to enter into the Agreement
and perform its obligations thereunder.

         2. The Agreement, and the other agreements contemplated thereby to
which Seller is a party (the "Seller Related Agreements"), have been duly
authorized by all necessary corporate action on the part of Seller and have been
duly executed and delivered by Seller. The Agreement and the Seller Related
Agreements constitute the legal, valid and binding obligations of Seller
enforceable against it in accordance with their terms, except as the
enforceability thereof may be subject to or limited by (a) bankruptcy,
insolvency, reorganization, arrangement, moratorium or other similar laws
relating to or affecting the rights of creditors and (b) general equitable
principles, regardless of whether the issue of enforceability is considered in a
proceeding in equity or at law.

         3. The execution and delivery of the Agreement and the Seller Related
Agreements, and the performance by Seller of its obligations thereunder, (a)
will not breach or result in a violation of Seller's Articles of Incorporation
or Bylaws, or any judgment, order or decree of any court or arbitrator, known to
us, to which Seller is a party or is subject, and (b) will not constitute a
material breach of the terms, conditions or provisions of, or constitute a
default under, any contract set forth in the Schedules to the Agreement.

         4. To our knowledge, no consent, approval or authorization of, or
designation, declaration or filing with, any governmental authority is required
in connection with the valid execution, delivery and performance by Seller of
the Agreement and the Seller Related Agreements, other than such consents,
approvals, authorizations, designations, declarations or filings as have been
made or obtained on or before the date hereof.

         5. Except as disclosed in the Agreement and the Seller Related
Agreements, there is, to our current actual knowledge, no action, suit or
proceeding pending against any of the Selling Parties in any court or before any
governmental authority or agency, or arbitration board or tribunal (a) which
seeks to restrain, enjoin, prevent the consummation of, or otherwise challenge
the Agreement or any of the Seller Related Agreements, or any of the
transactions contemplated thereby, or (b) which, if adversely determined, could
have a material adverse effect on Seller or its business or properties.

         6. Such other matters as counsel for Buyer may reasonably request.

                                CALL RECORD/NOTES

OFFICE SEARCH: The examining attorney has searched the Office records and has
found no similar registered or pending mark which would bar registration under
Trademark Act Section 2(d), 15 U.S.C. Section 1052(d). TMEP Section 1105.01.

RE:     Serial Number 75/16'3 8 1 0
- -----------------------------------

This case will be given priority as an amended case if Applicant or applicant's
attorney responds to the requirements stated below within two months of the
above mailing date. In any event a proper response to this Priority Action must
be received within SIX MONTHS from the mailing date stated above in order to
avoid ABANDONMENT.

         Applicant will amend the method of use statement to indicate that the
         mark- is intended to be used on labels attached to the goods and on
         instructional manuals for the goods.

         The applicant must indicate whether the person who signed the
         application is an officer of the applicant. TMEP Section 803.09. If
         not, the applicant should note the following.

         If the application was not signed by the applicant or by a person
         having color of authority to sign, the application is void. 37 C.F.R.
         Section 2.21(a)(6). To be properly signed, an application must be
         signed by the applicant, a member of the applicant firm (e.g., a
         general or active partner of an applicant partnership), or the officer
         of the applicant corporation or association. Trademark Act Section 1.
         15 U-S-C Section 105 1.

         If the application was not signed by the appropriate person as
         described above but the applicant asserts that the person who signed
         had color of authority to do so, the applicant must submit evidence
         that the person who signed:

                (1) had firsthand knowledge of the truth of the statements in 
         the verification or declaration and


                                      -2-

<PAGE>   62

                (2) had actual or implied authority to act on behalf of the 
         applicant.

If the examining attorney determines that the person who signed the application
had color of authority, the application will not be deemed void as filed.
However, a substitute verification or declaration under -'17 C.F.R. Section
2.20, signed by the proper person, must be submitted. 37 C.F.R. Section 2.71(c).

The following is a properly worded declaration under '37 C.F.R. Section 2.20. At
the end of the response, the applicant should insert the declaration signed by
an officer of applicant.

The undersigned, being hereby warned that willful false statements and the like
so made are punishable by fine or imprisonment, or both, under 18 ' U.S.C. 1001,
and that such willful false statements may jeopardize the validity of the
application or any resulting registration, declares that he/she is properly
authorized to execute this application on behalf of the applicant; he/she
believes the applicant to be the owner of the trademark/service mark sought to
be registered, or, if the application is being filed under 15 U.S.C. 1051(b),
he/she believes applicant to be entitled to use such mark in commerce; to the
best of his/her knowledge and belief no other person, firm, corporation, or
association has the right to use the mark in commerce, either in the identical
form thereof or in such near resemblance thereto as to be likely, when used on
or in connection with the goods/services of such other person, to cause
confusion, or to cause mistake, or to deceive; and that all statements made of
his/her own knowledge are true and all statements made on information and belief
are believed to be true.

business enterprises;

(4) Maintain records showing (i) procedures which have been adopted to comply
with the policies set forth in this clause, including the establishment of a
source list of minority and women's business enterprises, (ii) awards to

enterprises;

(5) Include the Utilization of Minority and Women's Business Enterprises clause
in subcontracts which offer substantial minority and women's business

                  policies, procedures and security requirements of Ameritech
                  (as defined herein). While on the premises of Ameritech,
                  Consultant will be responsible for any personal injury or

         a)       Any information, including but not limited to, specifications,
                  drawings, computer programs, technical or business information
                  or other data in whatever form (hereinafter "Information"),
                  which is proprietary to Ameritech and furnished by Ameritech
                  to Consultant, whether in writing, orally or visually, under
                  or in contemplation of this Agreement or to which Consultant

                  following:



i)      Consultant shall restrict disclosure of the Information to Consultant's
        employees with a "need to know" (i.e., employees that require the
        Information to perform their responsibilities in connection with this
        Agreement) and shall not disclose it to any other person or entity
        without the prior written consent of Ameritech;

ii)     Consultant shall use the Information only for purposes of performing 
        under this Agreement;

<PAGE>   5

iv)     Consultant shall copy the Information only as necessary for those
        employees who are entitled to receive it and shall ensure that all

                disclosure of the Information would cause irreparable harm to
                Ameritech for which it would have no adequate remedy at law, and
                that an actual or contemplated breach of this Clause shall
                entitle Ameritech to obtain immediate injunctive relief
                prohibiting such breach, in addition to any other rights
                available to it. This Agreement shall be deemed confidential

                survive the termination or expiration of this Agreement.



        c)      The Information shall not be considered confidential and shall
                not be subject to the foregoing if Consultant can demonstrate
                that the Information:



i)      is or becomes available to the public through no breach of this 
        Agreement;



ii)     was previously known by Consultant without any obligation to hold it in 
        confidence;

         TO THE EXTENT of such authorization;



vi)      is required by law or regulation to be disclosed, but only to the
         extent and for purposes of such required disclosure; or



vii)     IS disclosed in response to a valid order of a court or lawful request
         of a governmental agency, but only to the extent of and for the
         purposes of such order or request, provided that Consultant first
         notifies Ameritech of the order or request ten (1 0) days prior to
         disclosure and permits Ameritech to seek an appropriate protective
         order.



         d)       No Information furnished by Consultant to Ameritech hereunder
                  or in contemplation hereof shall be treated as confidential by
                  Ameritech unless specifically labeled as such by Consultant in
                  advance of its disclosure to Ameritech. In such event,
                  Ameritech shall safeguard and protect Consultant's
                  confidential Information in accordance with the provisions
                  above, except Ameritech may disclose such Information to its
                  employees and its Affiliates with a need to know.

9.       RIGHT IN MATERIALS AND INDEMNITY.

         a)       The Initial Market Survey prepared by or for Consultant in the
                  course of performing services under this Agreement shall be
                  promptly furnished to Ameritech upon completion of the
                  Project. The Initial Market Survey shall be the exclusive
                  property of Ameritech, including title to copyright in all
                  copyrightable material (to the extent derived from employees
                  and subcontractors of Consultant), and may be used by
                  Ameritech in any manner whatsoever so long as such use is not
                  in violation of this Agreement; shall be considered a "work
                  made for hire" consistent with U.S. copyright laws; and shall
                  be deemed and treated by Consultant as Ameritech's
                  confidential Information as described in Section 7 of this
                  Agreement. If any such materials were previously copyrighted
                  by Consultant and not originally prepared hereunder,
                  Consultant hereby grants to Ameritech an unrestricted
                  royalty-free license to copy such materials and the rights to
                  sublicense such materials to its Affiliates. Such materials do
                  not include Consultant's own proprietary and confidential
                  Information and property including but not limited to source
                  code, databases and software systems not originally designed,
                  created or implemented for Ameritech. Consultant warrants that
                  all 


<PAGE>   7



                  persons performing services hereunder are employees of
                  Consultant and the services performed and work product thereof
                  have been prepared by such employees within the scope of their
                  employment; or if not employees, Consultant has received from
                  such persons an assignment of copyright covering all services
                  performed hereunder. To the extent such materials shall not be
                  considered a "work made for hire," Consultant hereby assigns
                  all right, title, and interest in such materials to Ameritech.
                  Consultant agrees to cooperate with Ameritech and to execute
                  all documents reasonably necessary for the transfer,
                  maintenance and protection of these rights for the benefit of
                  Ameritech.



         b)       Consultant agrees to indemnify, defend and hold Ameritech
                  harmless against any claim, demand, cause of action, suit
                  liability, damage, loss, judgment, award, cost and expense
                  (including reasonable attorneys' fees and expenses) relating
                  to or arising out of a claim or assertion that any materials
                  produced or used by Consultant for Ameritech or otherwise
                  produced or used by Consultant in performing services
                  hereunder infringe or violate any patent, copyright or other
                  proprietary right (including, but not limited to,
                  misappropriation of trade secrets) of any third party.
                  Consultant shall defend and settle at its sole expense all
                  suits and proceedings arising out of the foregoing. No
                  settlement which prevents Ameritech from continuing to use
                  materials related to the services provided hereunder, shall be
                  made without Ameritech's prior written consent.



10.      INSURANCE.

Consultant shall purchase and maintain general liability insurance as is
reasonable under the circumstances to protect the Consultant and Ameritech from
claims which may arise out of the Consultant's performance of services
hereunder. All such insurance shall be purchased from and issued by insurance
companies reasonably satisfactory to Ameritech. All such insurance shall name
Ameritech as an additional named insured. Certificates of Insurance, evidencing
such coverage, shall be provided to Ameritech upon request. The minimum coverage
and limits to be maintained by Consultant shall be written for not less than the
limits of liability specified by further agreement of the parties, or as
required by law, whichever is greater.

               Consultant from and against claims, liabilities, obligations,
               suits, judgments, damages, expenses or costs (including
               reasonable attorneys' fees) (collectively, "Consultant's
               Damages") which may be asserted against or incurred by Consultant
               which arise out of Ameritech's performance or failure to perform

               foregoing indemnity shall not apply to Consultant's Damages
               resulting from or relating to Consultant's negligence or
               misconduct.

        b)     Consultant agrees that it will indemnify, defend and hold 
               harmless Ameritech from and against any and all claims,

               to Ameritech's Damages resulting from or relating to Ameritech's
               negligence or misconduct.

                  provides two-way cellular voice communication services or
