                                    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.

                                  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 that the Company's levels of profitability will not
vary significantly between quarters. 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, the
Company believes it is likely 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
 
                                        7
<PAGE>   10
 
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 two customers, 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 three customers, 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 loss of any of these customers would have a material adverse
effect on the Company's business, financial condition and results of operations.
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 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,
 
                                        8
<PAGE>   11
 
which will allow PSAP's 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.
 
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
 
                                        9
<PAGE>   12
 
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 payments for
such services. Because the Company historically 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
 
                                       10
<PAGE>   13
 
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 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
 
                                       11
<PAGE>   14
 
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
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
 
                                       12

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 key person life insurance policies only with respect
to Mr. Heinrichs, Mr. Sims and Ms. Hamilton. 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 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
 
                                       13
<PAGE>   16
 
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
 
     Although the Company has no present commitments or agreements with respect
to acquisitions, the Company may pursue, from time to time, the acquisition of
other companies, assets, products and technologies. 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 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
 
                                       14
<PAGE>   17
 
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 does not expect to incur substantial costs in
making its services and products Year 2000 compliant, but any 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; DILUTION
 
     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. In addition, investors participating
in this offering will incur immediate, substantial dilution. To the extent
outstanding options and warrants to purchase the Company's Common Stock are
exercised, there will be further dilution. 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
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."

<PAGE>   19
 
                                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 a portion of the proceeds to prepay $4.0 million
of 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 March 31,
1998) and are due on April 15, 1998. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Liquidity and Capital
Resources."
 
     The Company expects to use the balance of the net proceeds 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. No material
transactions of this nature are currently planned or being negotiated as of the
date of this Prospectus. 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
December 31, 1997: (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 1,106,610 shares of Common Stock issuable upon exercise of stock
    options outstanding as of December 31, 1997 at a weighted average exercise
    price of $3.03 per share, and 128,085 shares of Common Stock reserved for
    grant of future options as of December 31, 1997, under the 1990 Stock Option
    Plan. From January 1, 1998 to April 9, 1998, the Company issued 253 shares
    of Common Stock upon the exercise of outstanding options and granted options
    to purchase 14,498 shares of Common Stock pursuant to the 1990 Stock Option
    Plan. In addition, the number of shares reserved for issuance under the 1990

                                    DILUTION
 
     The pro forma net tangible book value of the Company at December 31, 1997
was approximately $1,263,000, or $0.15 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
December 31, 1997, would have been $27,805,000, or $2.66 per share. This
represents an immediate dilution of $11.34 per share to new investors purchasing
shares of Common Stock in this offering. The following table illustrates this
dilution:

    shares held by the existing stockholders to 7,141,754 or approximately 68.4%
    of the total number of shares of Common Stock outstanding after this

                      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 December 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.
 
     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.
 
     During the year ended December 31, 1996, the Company recognized
approximately 82% of total revenue from continuing operations from two
customers, each of which accounted for greater than 10% of the Company's total
revenue in such periods. During the year ended December 31, 1997, the Company
recognized
 
                                       21
<PAGE>   24
 
approximately 81% of total revenue from three 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. There is no assurance that the Company's existing net operating
loss carryforwards 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 that the Company's 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 charge, 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 and 1997, 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."

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
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 consists
primarily of labor and networking costs to maintain the related systems. 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
 
                                       23
<PAGE>   26
 
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 consists primarily of labor and related expenses. Costs
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 consist primarily of
expenses related to salaries and commissions, travel, trade shows and sales
collateral. 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 consist
primarily of expenses related to the Company's information systems, finance,
human resources, legal, executive and financial planning departments. General
and administrative expense 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. 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 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 for Income Taxes. The Company's income tax provision increased
from $9,000 in 1996 to $172,000 in 1997. This increase 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.
 
     License 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
 
                                       24
<PAGE>   27
 
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 expense 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 expense 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 December 31, 1997, the Company had $2.5 million in cash
and cash equivalents and $2.3 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 also paid $2.5 million and
$3.6 million in 1996 and 1997, respectively, toward its lease obligations for
capital equipment.
 
     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 March 31, 1998) and are due April 15, 1998. 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 does not expect to incur substantial costs in making its services and
products Year 2000 compliant, but any unanticipated expenses could have a
material 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 the next 12 months. Changes in the Company's plans or
other events affecting the Company's operations may result in accelerated or
unexpected expenditures that would affect the Company's cash requirements.
 
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 expects to adopt SFAS 130 for applicable
transactions in the first quarter of 1998.
 
                                       27

     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 also 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. Today, service providers require
more advanced ordering, service provisioning, service assurance and billing
systems to deliver services demanded by an increasingly competitive market.
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.
                                       29
<PAGE>   32
 
These OSS were further strained by the many incremental changes that 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
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
 
                                       30
<PAGE>   33
 
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 revenues 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.

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
 
                                       33
<PAGE>   36
 
     and analyses of information loaded into the NDSC systems. SCC employs 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
 
                                       34
<PAGE>   37
 
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 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
 
                                       35
<PAGE>   38
 
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 two customers, 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 three 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 1996 or 1997. 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 partial 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. At March 31, 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. 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 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 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
 
                                       37
<PAGE>   40
 
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
 
                                       38
<PAGE>   41
 
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
 
     At March 31, 1998, the Company employed 247 full-time employees in seven
states. Of these employees, 34 were involved in research and development, 18 in
sales and marketing, 158 in technical support and operations and 37 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.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     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 1998 Plan is to become
effective on the date the Underwriting Agreement for this offering is executed
(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 the Plan Effective
Date, 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 (i) an amount equal to 3% of the
number of shares of Common Stock outstanding on the last trading day of the
immediately preceding calendar year or (ii) a lesser amount determined by the
Board. To the extent any unvested shares of Common Stock issued under the
Predecessor Plan are repurchased by the Company after the Plan Effective Date,
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. In no event may any one
 
                                       42
<PAGE>   45
 
participant in the 1998 Plan receive option grants, 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 Plan Effective Date, 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 100% of 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 100% of 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, if so activated, will allow executive
officers and other highly compensated employees the opportunity to apply a
portion of their base salary to the acquisition of special below-market stock
option grants; (iv) the Automatic Option Grant Program, which may, in the
Board's sole discretion, be activated for one or more calendar years and under
which option grants would automatically be made at periodic intervals to
eligible non-employee Board members to purchase shares of Common Stock at an
exercise price equal to 100% of their fair market value on the grant date; and
(v) the Director Fee Option Grant Program, which may, in the Plan
Administrator's discretion, be activated for one or more calendar years and, if
so activated, would allow non-employee Board members the opportunity to apply a
portion of the annual retainer fee, if any, otherwise payable to them in cash
each year to the acquisition of special below-market option grants.
 
     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 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 of salary invested in that option. The
option will vest in a series of 12 equal monthly installments over the
 
                                       43
<PAGE>   46
 
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, should the Automatic Option Grant
Program be activated in the future, each individual who first becomes a
non-employee Board member at any time after such date will receive an option
grant on the date such individual joins the Board. In addition and on the date
of each Annual Stockholders Meeting held after the Plan Effective Date, each
non-employee Board member who is to continue to serve as a non-employee Board
member will automatically be granted an option to purchase 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 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 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 any 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 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 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 7, 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 at January 1 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;
however, the initial offering period began on March 1, 1998 and continues
through December 31, 1998. The Purchase Plan may be administered by the Board of
Directors or a committee appointed by the Board. Employees (including officers
and employee directors) of the Company are eligible to participate if they are
employed by the Company for at least
 
                                       44
<PAGE>   47
 
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 Amended and 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.,

     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

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

Directors and executive officers, effective upon the effectiveness of the

                          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 9, 1998, there were 8,342,007 shares of Common Stock
outstanding held of record by 122 stockholders. As of April 9, 1998, options to
purchase an aggregate of 1,113,613 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 shareholders and may
adversely affect the market price of, and the voting and other rights of, the
holders of Common Stock. The Company has no current plans to issue any shares of
Preferred Stock.
 
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
 
                                       49
<PAGE>   52
 
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 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 Amended and 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 Chairman of the Board
or a majority of the Board will be permitted to call a special meeting of
stockholders. The Amended and 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 supermajority vote of members of the Board
or stockholders to amend certain provisions of the Amended and Restated Bylaws.
These provisions of the Amended and Restated Certificate of Incorporation and
the Amended and 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. There were also approximately 625,129 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 Rule 701 under the Securities Act ("Rule 701").
 
     The Company, the executive officers and Directors of the Company, and
certain security holders 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
significant amounts of the Common Stock of the Company in the public market
could adversely affect the
 
                                       51
<PAGE>   54
 
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 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 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 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
(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 management intends to renew, 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.
Capitalized software is amortized using the straight-line method over 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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
     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.
 
                                       F-9

                            SCC COMMUNICATIONS CORP.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
FAIR MARKET VALUE OF FINANCIAL INSTRUMENTS
 
     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 earnings 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.
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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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 expects to adopt SFAS 130 for applicable
transactions in the first quarter of 1998.
 
     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 $0.28 and $0.26, respectively for the year
ended December 31, 1997.
 
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,

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.
 
     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

assumptions:

Expected volatility................................      0.00%        0.00%        0.00%
</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.
 
     A summary of stock options under the 1990 Option Plan as of December 31,
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.

1996 and 1997, no employer matching or discretionary contributions were made to
the 401(k) plan.
 
(10) RELATED PARTY TRANSACTION

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.
 
     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>   84
 
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 March 31, 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 235,066 shares of Common Stock were issued through the
     exercise of options granted under the 1990 Option Plan for an aggregate
     exercise price of $157,368. 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.

1(c) and 1(d) below), the Holder of those Registrable Securities shall give
written notice to the Company of the proposed disposition and shall have
furnished the Company with a detailed statement of the circumstances
surrounding the proposed disposition; provided, however, that the Holder need
not provide such notice with respect to Registrable Securities for which the
Company has previously issued unlegended certificates.

                          (2)     Except with respect to transactions not
involving a change in beneficial ownership or transactions involving the
distribution without consideration of Registrable Securities by any of the
Holders to any of its partners, retired partners, or any estate of its partners
or retired partners, or transfer by gift, will or intestate succession by any
partner to his spouse or lineal descendants or ancestors, or to any
stockholder, affiliate or affiliated venture capital partnership, such notice
shall, if reasonably requested by the Company, also be accompanied by a written
opinion of legal counsel (who shall be reasonably satisfactory to the Company
and its counsel) stating that the proposed disposition of the Registrable
Securities may be effected without registration under the Act and without blue
sky qualification.  It is agreed that the Company will not require opinions of
counsel for transactions made pursuant to Rule 144 except in unusual
circumstances.

                          (3)     Having satisfied Subsection 1(b)(2) above,
the Holder of such Registrable Securities shall be entitled to transfer the
Registrable Securities in accordance with the terms of the notice delivered by
the Holder to the Company.

                          (4)     Each certificate evidencing the Registrable
Securities shall  (unless otherwise permitted by the provisions of this
Agreement) be stamped or otherwise imprinted with a legend substantially in the
following form in addition to any legend required under applicable state
securities laws:

               THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED
               FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE
               SECURITIES ACT OF 1933.  SUCH STOCK MAY NOT BE SOLD,
               TRANSFERRED, ASSIGNED OR HYPOTHECATED, UNLESS THERE IS AN


                                     - 3 -
<PAGE>   4
               EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH
               SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 OR ITS
               SUCCESSOR RULE UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION
               OF COUNSEL FOR THE HOLDER OF THESE SECURITIES WHO IS REASONABLY
               SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
               ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
               PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

The Company shall remove such restrictive legend upon the request of any Holder
if (i) the Company has received an opinion of counsel who is reasonably
acceptable to it and its counsel to the effect that registration of any and all
future transfers is not required, (ii) an appropriate registration statement
with respect to such Registrable Securities has been filed by the Company with
the Commission and been declared effective by the Commission, or (iii) such
transfer may be made in compliance with the requirements of Rule 144 or its
successor.  In these events, the Company shall cause new certificates without
the above legend to be issued promptly to the Holder in exchange for
outstanding legended certificates.

                 (c)      Company Registration.

                          (1)     Notice and Piggyback Rights.  If at any time
the Company  shall decide to register any of its securities, the Company shall:

                                  A.       promptly give to each Holder written
notice of the registration (which shall include a list of the jurisdictions in
which the Company intends to attempt to qualify such securities under the
applicable Blue Sky laws); and

                                  B.       include in such registration (and
any related Blue Sky qualification or other compliance reasonably requested by
Holders in order to sell such securities), and in any underwriting involved,
all the Registrable Securities specified in a written request, made within 30
days after receipt of such written notice from the Company, by any Holder or
Holders, except as set forth in Subsection 1(c)(2) below.


                                     - 4 -
<PAGE>   5
                 The provisions of this subsection do not apply to any of the
following:  (i) a registration on any registration form which would not permit
secondary sales by a Holder, (ii) a registration which relates solely to
employee benefit plans, or (iii) a registration which relates solely to a
Commission Rule 145 transaction.

                          (2)     Underwriting; Limits.  If the registration of
which the Company gives notice is for a registered public offering involving an
underwriting, the Company shall so advise the Holders as a part of the written
notice given pursuant to Subsection 1(c)(1).  All Holders proposing to
distribute their Registrable Securities through such underwriting shall enter
into an underwriting agreement in customary form with the underwriters selected
by the Company.  Notwithstanding any other provision of this Section (c), if
the underwriter determines that marketing factors require a limitation of the
amount of securities to be registered, the Company shall include in such
registration, prior to the inclusion of any other securities which are not
Registrable Securities (except those held by the Company), the number of
Registrable Securities requested to be included which in the opinion of such
underwriters can be sold, pro rata among the respective Holders on the basis of
the amount of Registrable Securities requested to be registered by each Holder.
In any event, all limitations on the number of Registrable Securities to be
included in the applicable underwriting shall be pro rata with respect to the
number of Registrable Securities requested to be registered as between Holders
as of the date of the notice provided pursuant to Subsection 1(c)(1)(A).  If
any Holder disapproves of the terms of any such underwriting, he may elect to
withdraw therefrom by written notice to the Company and the underwriter within
five (5) days after receipt of such notice, and any Registrable Securities
excluded or withdrawn from such underwriting shall be withdrawn from
registration.

                 (d)      Registration at the Request of the Holders.

                          (1)     Two Requests; Mechanics.  At any time after
the effective date of the Company's initial public offering, Initiating Holders
may, upon delivery of written notice to the Company specifying this Section
1(d), require the Company to use its best efforts to prepare and file a
registration statement and other qualifications or compliances with respect to
all or part of the Registrable Securities; provided, however, that for the
second request for registration under this Section 1(d)(1), Initiating Holders
shall mean the holders of at least 30% of the Registrable Securities.

                 In the event of such a request, the Company shall:

                                  A.       Promptly give written notice of the
proposed registration, qualification, or compliance to all other Holders.

                                  B.       Use its diligent best efforts to
file as soon as practicable, but in any event within ninety (90) days after
receipt of the request or requests of the Initiating Holders, all such
registrations, qualifications, and compliances as may be so requested and as
would facilitate the sale and distribution of all or such portion of the
Holders' Registrable Securities as are specified in their request.


                                     - 5 -
<PAGE>   6
                                  C.       Include in such registrations,
qualifications, and compliances  the Registrable Securities of any Holders who
ask in writing, within thirty (30) days after receipt of notice under
Subsection 1(d)(1)(A), to join in such request.

                                  D.       The Company may be required to
prepare, file, and keep effective a registration statement under this Section
1(d) on no more than two (2) occasions.

                          (2)     Exceptions.  The Company shall not be
obligated to effect any registration, qualification, or compliance requested by
a Holder with respect to a proposed distribution of Registrable Securities by a
Holder under this Section 1(d):

                                  A.       if the Company has not previously 
effected an initial public offering; or

                                  B.       in any particular jurisdiction in
which the Company would be required to execute a general consent to service of
process in effecting such registration, qualification or compliance; or

                                  C.       within six (6) months following the
effective date of any public offering to the general public of the Company's
securities for its own account, or

                                  D.       the Company has effected two (2)
such registrations pursuant to this Section 1(d) and such registrations have
been declared and ordered effective.

                 If the Company shall furnish to such Holders a certificate
signed by the President of the Company stating that in the good faith judgment
of the Board of Directors it would be seriously detrimental to the Company and
its shareholders for a registration statement to be filed in the near future,
then the Company's obligation to use its best efforts to file a registration
statement under this Section 1(d) shall be deferred for a period during which
such filing of a registration  statement would be seriously detrimental,
provided that this period will not exceed ninety (90) days, and provided
further that the Company shall not defer its obligations in this manner more
than once in any twelve-month period.

                          (3)     Underwriting.  If the Initiating Holders
intend to distribute the Registrable Securities covered by their request by
means of an underwriting, they shall so advise the Company as a part of their
request made pursuant to Section 1(d).

                                  A.       The Company shall include such
information in the written notice referred to in Subsection 1(d)(1)(A).



                                     - 6 -
<PAGE>   7
                                  B.       The Initiating Holders shall
negotiate with an underwriter selected by the Initiating Holders and reasonably
approved by the Company, with regard to the underwriting of the requested
registration.  But if a majority in interest of the Initiating Holders have not
agreed with the underwriter as to the terms and conditions of the underwriting
within ten (10) days following commencement of such negotiations, a majority in
interest of the Initiating Holders may select another underwriter of their
choice.

                                  C.       The right of any Holder to include
his Registrable Securities in a registration pursuant to Section 1(d) shall be
conditioned upon the Holder's participation in such underwriting, on the terms
and conditions of such underwriting and upon the inclusion of the Holder's
Registrable Securities in the underwriting (unless otherwise mutually agreed by
a majority in interest of the Initiating Holders and such Holder).

                                  D.       The Company shall (together with all
Holders proposing to distribute their securities through such underwriting)
enter into an underwriting agreement in customary form with the underwriter or
underwriters selected for the underwriting by a majority in interest of the
Initiating Holders.

                                  E.       Notwithstanding any other provision
of this Section  1(d), if the underwriter advises the Initiating Holders in
writing that marketing factors require a limitation of the number of shares to
be underwritten, the Initiating Holders shall so advise all holders of
Registrable Securities.  The Company shall then include in such registration,
prior to the inclusion of any other securities which are not Registrable
Securities, the number of shares of Registrable Securities that the underwriter
believes may be included in the registration in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities held at that
time by such Holders.

                                  F.       If any Holder of Registrable
Securities disapproves of the terms of the underwriting, he may elect to
withdraw from the underwriting by written notice to the Company, the
underwriter and the Initiating Holders within five (5) days of notice to such
Holder of the terms of the underwriting.  Any Registrable Securities which are
excluded from the underwriting by reason of the underwriter's marketing
limitation or withdrawn from the underwriting shall be withdrawn from the
registration.

                          (4)     Form S-3.  The Company shall use its best
efforts to qualify for registration on Form S-3 (including any equivalent
successor form) after one (1) year from the effective date of its first
registration statement filed with the Commission.

                                  A.       After the Company has qualified for
the use of Form S-3, Holders of Registrable Securities shall have the right to
request an unlimited number of registrations on Form S-3, provided that the
Registrable Securities requested to be so registered shall represent
Registrable Securities having an anticipated market value of no less than
$500,000.  Such request shall be in writing and shall state the number of
shares of Registrable Securities to be disposed of and the intended method of
disposition of shares by such Holders.



                                     - 7 -
<PAGE>   8
The Company shall not  be required to effect a registration pursuant to this
paragraph within 90 days of the effective date of any registration referred to
in Section 1(c) and Subsection 1(d)(1) or of the last registration effected
pursuant to this Subsection 1(d)(4).

                                  B.       The Company shall give written
notice to all Holders of Registrable Securities of the receipt of a request for
registration pursuant to this Subsection 1(d)(4) and shall provide a reasonable
opportunity for other Holders to participate in the registration.  If the
registration is for an underwritten offering, the terms of Subsection 1(d)(3)
shall apply to all participants in such offering.

                                  C.       The Company will use its best
efforts to effect promptly the registration and qualification for sale of all
shares of Registrable Securities on Form S-3 to the extent requested by the
Holders for purposes of disposition.

                 (e)      Expenses of Registration.

                          (1)     Registration Expenses.  All Registration
Expenses incurred in connection with registration, filing, qualification, and
compliance under Section 1(c) and 1(d)(4) and both registrations under Section
1(d)(1) shall be borne by the Company provided that Holders of securities being
registered pursuant to Section 1(c) agree that they will pay (on a pro rata
basis among those Holders selling Registrable Securities in a particular state)
all Blue Sky fees associated with the registration of Registrable Securities in
those states in which the Company is not otherwise registering or qualifying
shares of its stock for sale in such registration.

                          (2)     Selling Expenses.  All Selling Expenses
incurred in connection with these transactions shall be borne by the Holders of
the securities so registered pro rata on the basis of the amount of Common
Stock so registered.

                          (3)     Legal Expenses.  Each Holder shall bear its
own expenses,  if any, for the fees and disbursements of counsel to such Holder
incurred in connection with these transactions, except that the Company will
pay for one special counsel to Selling Holders in connection with one
registration effected under Section 1(d)(1).

                          (4)     Ineffective Requested Registration.  The
Company shall not be required to pay any Registration Expenses if the
registration statement does not become effective as a result of the withdrawal
of a request for registration by the Initiating Holders pursuant to Subsection
1(d)(1), which withdrawal was not caused by the Company's failure to comply
with applicable registration requirements and regulations, or by the Company's
failure to disclose to Initiating Holders information about the existence of a
Material Adverse Event (as that term is defined in the Purchase Agreement).  In
such case, the Initiating Holders shall bear such Registration Expenses pro
rata on the basis of the number of shares of each Initiating Holder included in
the registration request, and such registration shall not be counted as a
registration pursuant to Subsection 1(d)(1), or the Initiating Holders will not
bear such expenses and such registration shall be counted as a registration
pursuant to Subsection 1(d)(1).

<PAGE>   9
                 (f)      Registration Procedures.  In the case of each
registration, qualification, or compliance effected by the Company pursuant to
this Agreement, the Company shall keep each Holder advised in writing as to the
initiating of each registration, qualification, and compliance and as to the
completion thereof.  At its expense the Company shall:

                          (1)     Keep such registration statement effective
until the Holders have completed the distribution described in the registration
statement but for not more than one hundred twenty (120) days (or, if the
registration is underwritten, ninety (90) days).

                          (2)     Furnish such number of prospectuses
(including preliminary  prospectuses) and other documents incident to the
registration as a Holder from time to time may reasonably request.

                          (3)     At the time when any registration statement
becomes effective, and at the time when any post-effective amendment becomes
effective, furnish to the Holders registering securities, an opinion of counsel
satisfactory to the Holders to the effect that:

                                  A.       To the best of Counsel's knowledge,
no stop order suspending the effectiveness of the registration statement has
been issued, and no proceedings for that purpose have been instituted or are
pending or contemplated under the Securities Act.

                                  B.       The registration statement and the
prospectus, and each amendment or supplement to the Registration Statement, as
of their respective effective or issue dates, comply as to form in all material
respects with the requirements of the Securities Act and the rules and
regulations of the Commission.

                                  C.       Counsel has no reason to believe
that the registration statement, the prospectus, or any amendment or supplement
thereto, contained any untrue statement of material fact or omitted to state a
material fact necessary to make the statements in the documents not misleading.

                                  D.       The descriptions in the registration
statement, the prospectus and any amendment or supplement, of statutes, legal
and government proceedings, and contracts and other documents are accurate and
fairly present the information required to be shown, and include all required
statutes, proceedings, contracts, and documents.

                          (4)     Notify each Holder of Registrable Securities,
at any time when a prospectus relating thereto is required to be delivered
under the Securities Act, of the happening of any event as a result of which
the prospectus included  in such registration statement contains an untrue
statement of a material fact or omits any fact necessary to make the statements
therein not misleading, and at the request of any such Holder, the Company will
prepare a supplement or


                                     - 9 -
<PAGE>   10
amendment to such prospectus so that, as thereafter delivered to the purchasers
of such Registrable Securities, such prospectus will not contain an untrue
statement of a material fact or omit to state any fact necessary to make the
statements therein not misleading.

                          (5)     Cause all such Registrable Securities to be
listed on each securities exchange on which similar securities issued by the
Company are then listed and, if not so listed, to be listed on the NASD
automated quotation system.

                          (6)     Provide a transfer agent and registrar for
all such Registrable Securities not later than the effective date of such
registration statement.

                          (7)     Obtain a cold comfort letter from the
Company's independent public accountants in customary form and covering such
matters of the type customarily covered by cold comfort letters as the Holders
may reasonably request (provided that such Registrable Securities constitute at
least 10% of the securities covered by such registration statement).

                 (g)      Indemnification.

                          (1)     Company's Obligation to Indemnify.

                                  A.       Generally.  With respect to any
registration, qualification, or compliance which has been effected pursuant to
this Agreement, the Company shall indemnify each Holder, its officers,
directors, and partners and each person controlling such Holder, each legal
counsel, and each underwriter, against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue or alleged untrue statement of, or omission or alleged omission of a
material fact contained in, or required to be stated in, any registration
statement, including any preliminary or final prospectus, offering circular or
other document  incident to any such registration, qualification, or
compliance.  The Company shall further indemnify them against any violation or
alleged violation by the Company of any rule or regulation promulgated under
the Securities Act or any applicable state securities law in connection with
any such registration, qualification, or compliance.

                                  B.       Reimbursement.  The Company shall
promptly reimburse each such Holder, and each of its officers, directors,
partners, and controlling persons, each legal counsel and each such
underwriter, for any legal and any other expenses reasonably incurred, as such
expenses are incurred, in connection with investigating or defending any such
claim, loss, damage, liability, or action.

                                  C.       Limits of Obligation.  The Company
shall not be liable in any such case to the extent that any claim, loss,
damage, liability, or expense arises out of any untrue statement (or alleged
untrue statement) or omission (or alleged omission) made in such registration
statement, including any preliminary or final prospectus, offering circular or
other document, is based upon written information furnished to the Company by
an instrument duly executed by such Holder or underwriter, and which is stated
to be specifically for use therein.


                                     - 10 -
<PAGE>   11
                                  D.       Survival of Obligation.  The
obligations of the Company under this Section 1(g) shall survive the redemption
and conversion, if any, of the Preferred Stock, the completions of the
offerings of Registrable Securities under the registration statements, and
otherwise.

                          (2)     Holder's Obligation to Indemnify.

                                  A.       Generally.  If Registrable
Securities held by any Holder are included in the securities as to which the
registration, qualification, or compliance is being effected, each such Holder
shall indemnify the Company, each of its officers and directors, each legal
counsel and independent accountant of  the Company, each underwriter of the
Company's securities covered by such a registration statement, each person who
controls the Company within the meaning of the Act and each other such Holder,
each of its officers, directors and partners, each person controlling such
Holder, and each legal counsel against all claims, losses, damages, and
liabilities (or actions in respect thereof) arising out of or based on any
untrue or alleged untrue statement of, or omission or alleged omission of a
material fact contained in, or required to be stated in, any registration
statement, including any preliminary or final prospectus, offering circular, or
other document.

                                  B.       Reimbursement.  Furthermore, each
such Holder shall promptly reimburse the Company, such Holders, underwriters,
legal counsel and independent accountants and all of their respective officers,
directors, partners, and controlling persons for any legal or any other
expenses reasonably incurred, as such expenses are incurred, in connection with
investigating or defending any such claim, loss, damage, liability, or action.


                                     - 11 -
<PAGE>   12
                                  C.       Limits of Obligation.  In any case,
(i) any Holder's obligation under this Subsection 1(g)(2) shall extend only so
far as the untrue statement (or alleged untrue statement) or omission (or
alleged omission) is made in such registration statement, including any
preliminary or final prospectus, offering circular, or other document in
reliance upon written information furnished to the Company by an instrument
duly executed by such Holder and which is stated to be specifically for use
therein; and (ii) any Holder's liability under this Section 1(g)(2) shall not
exceed the amount of proceeds to the Holder from the sale of its Registrable
Securities in that offering.

                                  D.       Survival of Obligation.  The
obligations of the Holders under this Section 1(g) shall survive the
completions of the offerings of Registrable Securities under the registration
statements and otherwise.

                          (3)     Indemnifying Party May Assume Defense.

                                  A.       Generally.  Each party entitled to
indemnification under  this Section 1(g) (the "Indemnified Party") shall give
written notice to the party required to provide indemnification (the
"Indemnifying Party") promptly after such Indemnified Party has actual
knowledge of any claim as to which indemnity may be sought.  Unless in such
Indemnified Party's reasonable judgment a conflict of interest between such
Indemnified and Indemnifying Parties may exist with respect to such claim, the
Indemnified Party shall permit the Indemnifying Party to assume the defense of
any such claim or any resulting litigation; provided, however, that counsel for
the Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be approved by the Indemnified Party (whose approval shall
not be unreasonably withheld), and the Indemnified Party may participate in
such defense at its own expense.  Failure by the Indemnified Party to provide
such written notice shall not relieve the Indemnifying Party from its
obligation under this Section 1(g).

                                  B.       Settlement Approval, Release
Required.  No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent
to entry of any judgment or enter into any settlement which does not include as
an unconditional term the giving by the claimant or plaintiff to the
Indemnified Party of a release from all liability in respect to such claim or
litigation.  Furthermore, the failure of any Indemnified Party to give notice
as provided herein shall not relieve the Indemnifying Party of its obligations
under this Agreement.

                          (4)     Contribution.

                                  A.       If recovery is not available under
the foregoing indemnification provisions of this section for any reason other
than as specified therein, the parties entitled to indemnification by the terms
thereof shall be entitled to contribution for liabilities and expenses, except
to the extent that contribution is not permitted  under the Securities Act.  In
determining the amount of contribution to which the respective parties are
entitled, there shall be considered the relative benefits received by each
party from the offering of the securities (taking into account the portion of
the proceeds of the offering realized by each), the parties' relative knowledge
and access to information concerning the matter with respect to which the claim
was asserted, the party who supplied or failed to supply the information as to
which the claim is asserted, the opportunity to correct and prevent any
statement or omission, and any other equivalent considerations appropriate
under the circumstances; provided that in no event will any Holder be required
to contribute an amount in excess of the proceeds to the Holder from the sale
of its Registrable Securities included in that offering.  The Company and the
Holders agree that it would not be equitable if the amount of such contribution
were determined by pro rata or per capita allocations.

                 (h)      Information by Holder.  The Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding the Holders and the distribution proposed by the Holders,
as the Company may request in writing and as shall be required in connection
with any registration, qualification, or compliance referred to in this
Agreement.

                 (i)      Rule 144 Reporting.  With a view to making available
the benefits of certain rules and regulations of the Commission which may
permit the sale of the Registrable Securities to the public without
registration, the Company agrees that at all times after 90 days after the
effective date of the first registration statement filed by the Company for a
public offering of its securities the Company shall:

                          (1)     Make and keep public information available,
as  those terms are understood and defined in Rule 144 under the Securities
Act.

                          (2)     Use its best efforts to file with the
Commission in a timely  manner all reports and other documents required of the
Company under the Securities Act and the Securities Exchange Act of 1934, as
amended (the "Exchange Act").



                                     - 13 -
<PAGE>   14
                          (3)     So long as a Holder owns any Registrable
Securities, furnish to such Holder upon request: (i) a written statement by the
Company as to its compliance with the reporting requirements of Rule 144, the
Securities Act and the Exchange Act; (ii) a copy of the most recent annual or
quarterly report of the Company; and (iii) such other reports and documents so
filed by the Company as such person may reasonably request in availing itself
of any rule or regulation of the Commission allowing that person to sell any
such securities without registration.

                 (j)      Transfer of Registration Rights.  The right to cause
the Company to register Registrable Securities pursuant to this Section may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities who (1) is a partner, shareholder, affiliate,
equity holder or officer of the transferor Holder; or (2) after such assignment
or transfer, holds at least 125,000 shares of Registrable Securities (subject
to appropriate adjustment for stock splits, stock dividends, combinations and
other recapitalizations), provided the Company is, within ten (10) business
days after such transfer, furnished with written notice of the name and address
of such transferee or assignee and the securities with respect to which such
registration rights are being assigned; and provided, further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Securities Act.

                 (k)      Limitations on Subsequent Registration Rights.  From
and after the date hereof, the Company will not, without the prior written
consent of Holders of at least 75% of the voting power of the then outstanding
Registrable Securities, enter into any agreement with any holder or prospective
holder of any securities  of the Company providing for registration rights more
favorable than those granted to the Holders hereunder or which allows such
holder or prospective holder of any securities of the Company to include such
securities in any registration filed under Sections 1(c) or 1(d) hereof, unless
under the terms of such agreement, such holder or prospective holder may
include such securities in any such registration only to the extent that the
inclusion of his securities will not diminish the amount of Registrable
Securities which are included.

                 (l)      Termination of Registration Rights.  The registration
rights granted pursuant to this Section 1 shall terminate with respect to any
particular Registrable Securities upon the later to occur of: (i) ten (10)
years after the closing of the Company's initial public offering; or (ii) the
date on which all of such Registrable Securities may be resold pursuant to the
provisions of Rule 144(k) of the Commission.

                 (m)      Lock-Up.  Upon the request of the Company or any
underwriter's representative in connection with the public offering of the
Company's Common Stock pursuant to registration statements filed with, and
declared effective by, the Commission under the Securities Act, the Holders
agree not to sell or otherwise transfer any securities of the Company for a
period of 90 days following the effective date of the applicable registration
statements.

right, power or remedy of the Company or such Holder nor will it be construed
to be a waiver of any such breach or default, or an acquiescence therein, nor

                            SCC COMMUNICATIONS CORP.              
                             1990 STOCK OPTION PLAN


1.  PURPOSE

The SCC 1990 STOCK OPTION PLAN ("Plan") provides for the grant of Stock
Options, Stock Appreciation Rights and Supplemental Bonuses to employees,
directors and consultants of Systems Concepts of Colorado, Inc. (the
"Company"), and such of its subsidiaries (as defined in Section 425(f) of the
Internal Revenue Code of 1986 (the "Code") as the Board of Directors of the
Company shall from time to time designate ("Participating Subsidiaries") in
order to advance the interests of the Company and its Participating
Subsidiaries through the motivation, attraction and retention of key personnel.

2.  INCENTIVE STOCK OPTIONS AND NON-INCENTIVE STOCK OPTIONS

The Stock Options granted under the Plan may be either:

         a)  Incentive Stock Options ("ISOs") which are intended to be
         "Incentive Stock Options" as that term is defined in Section 422A of
         the Code; or

         b)  Nonstatutory Stock Options ("NSOs") which are intended to be
         options that do not qualify as "Incentive Stock Options" under Section
         422A of the Code.

All Stock Options shall be ISOs unless the Option Agreement clearly designates
the Stock Options granted thereunder, or a specified portion thereof, as NSOs.
Subject to the other provisions of the Plan, a Participant may receive ISOs and
NSOs at the same time, provided that the ISOs and NSOs are clearly designated
as such.

Except as otherwise expressly provided herein, all of the provisions and
requirements of the Plan relating to Stock Options shall apply to ISOs and
NSOs.

3.  ADMINISTRATION

         3.1.  COMMITTEE.  With respect to grants of Stock Options to Employees
(other than Employees who are directors of the Company) and grants of Stock
Appreciation Rights and Supplemental Bonuses to Employees (other than Employees
who are officers or directors of the Company), the Plan shall be administered
by a committee ("Committee") composed of at least three members of the Board of
Directors.  With respect to grants of Stock Options to directors and
consultants and grants of Stock Appreciation Rights and Supplemental Bonuses to
officers and directors, the Plan shall be administered by the Board of
Directors, a majority of whom are Disinterested Persons, or by a committee of
three or more persons, all of whom are Disinterested Persons.  Such committee
may be the Committee if all of the members thereof are Disinterested Persons,
or a special committee appointed by the Board of Directors composed of at least
three Disinterested Persons.  The Committee or the Board of Directors, as the
case may be, shall have full authority to administer the Plan, including
authority to interpret and construe any provision of the Plan and any Stock
Options, Stock Appreciation Rights or Supplemental Bonus granted thereunder,
and to adopt such rules and regulations for administering the Plan as it may
deem necessary in order to comply with the requirements of the Code or in order
that Stock Options that are intended to be ISOs will be classified as incentive
stock options under the Code, or in order to conform to any regulation or to
any change in any law or regulation applicable thereto.  The Committee or the
Board may delegate any of its responsibilities under the Plan, other than its
responsibility to grant Stock Options, to determine whether the Stock
Appreciation Rights or Supplemental Bonuses, if any, payable to a Participant
shall be paid in cash, in shares of Common Stock or a combination thereof, or
to interpret and construe the Plan.  The Board of

Directors may reserve to itself any of the authority granted to the Committee
as set forth herein, and it may perform and discharge all of the functions and
responsibilities of the Committee at any time that a duly constituted Committee
is not appointed and serving.  All references in this Plan to the "Committee"
shall be deemed to refer to the Board of Directors whenever it is discharging
the powers and responsibilities of the Committee, and to any special committee
appointed by the Board of Directors to administer particular aspects of the
Plan.

         3.2.  ACTIONS OF COMMITTEE.  All actions taken and all interpretations
and determinations made by the Committee in good faith (including
determinations of Fair Market Value) shall be final and binding upon all
Participants, the Company and all other interested persons.  No member of the
Committee shall be personally liable for any action, determination or
interpretation made in good faith with respect to the Plan, and all members of
the Committee shall, in addition to their rights as directors, be fully
protected by the Company with respect to any such action, determination or
interpretation.

4.  DEFINITIONS

         4.1.  "Stock Option."  A Stock Option is the right granted under the
Plan to an Employee, director, or consultant to purchase, at such time or times
and at such price or prices ("Option Price") as are determined by the
Committee, the number of shares of Common Stock determined by the Committee.

         4.2.  "Stock Appreciation Right."  A Stock Appreciation Right is the
right to receive payment, in shares of Common Stock, cash or a combination of
shares of Common Stock and cash, of the Redemption Value of a specified number
of shares of Common Stock then purchasable under a Stock Option.

         4.3.  "Redemption Value."  The Redemption Value of shares of Common
Stock purchasable under a Stock Option shall be the amount, if any, by which
the Fair Market Value of one share of Common Stock on the date on which the
Stock Option is exercised exceeds the Option Price for such share.

         4.4.  "Common Stock."  A share of Common Stock means a share of
authorized but unissued or reacquired common stock of the Company.

         4.5.  "Fair Market Value."  If the Common Stock is not traded
publicly, the Fair Market Value of a share of Common Stock on any date shall be
determined in good faith by the Board of Directors or the Committee after such
consultations with outside legal, accounting and other experts as the Board of
Directors or the Committee may deem advisable, and the Board of Directors or
the Committee shall maintain a written record of its method of determining such
value.  If the Common Stock is traded publicly, the Fair Market Value of a
share of Common Stock on any date shall be the average of the representative
closing bid and asked prices, as quoted by the National Association of
Securities Dealers through NASDAQ (its automated system for reporting quotes),
for the date in question, or, if the Common Stock is listed on the NASDAQ
National Market System or is listed on a national stock exchange, the
officially quoted closing price on NASDAQ or such exchange, as the case may be,
on the date in question.

      4.6.  "Employee."  An Employee is an employee of the Company or any
Participating Subsidiary.

         4.7.  "Participant."  A Participant is an Employee, director or
consultant to whom a Stock Option is granted, or an Employee to whom a Stock
Appreciation Right, or Supplemental Bonus is granted.

         4.8.  "Disinterested Person."  A Disinterested Person is a person who,
at the time he exercises discretion in administering the Plan, is not eligible,
and has not at any time within one year prior thereto been eligible for
selection as a person to whom Stock Options, Stock Appreciation Rights or
Supplemental Bonuses may be granted under this Plan or any similar plan of the
Company.

         4.9.  "Supplemental Bonus."  A Supplemental Bonus is the right to
receive payment, in shares of Common Stock, cash or a combination of shares of
Common Stock and cash, of an amount determined under Section 7.7.

5.  ELIGIBILITY AND PARTICIPATION

Grants of Stock Options, Stock Appreciation Rights and Supplemental Bonuses may
be made to Employees of the Company or any Participating Subsidiary.  Grants of
NSOs may be made to directors of or consultants to the Company or any
Participating Subsidiary.  Any director of the Company or of a Participating
Subsidiary who is also an Employee shall also be eligible to receive Stock
Options, Stock Appreciation Rights and Supplemental Bonuses. The Committee
shall from time to time determine the Participants to whom Stock Options shall
be granted, the number of shares of Common Stock subject to each Stock Option
to be granted to each such Participant, the Option Price of such Stock Options,
all as provided in this Plan.  The Option Price of any ISO shall be not less
than the Fair Market Value of a share of Common Stock on the date on which the
Stock Option is granted, but the Option Price of an NSO may be less than the
Fair Market Value on the date the NSO is granted if the Committee so
determines.  If an ISO is granted to an Employee who then owns stock possessing
more than 10% of the total combined voting power of all classes of stock of the
Company or any parent or subsidiary corporation of the Company, the Option
Price of such ISO shall be at least 110% of the Fair Market Value of the Common
Stock subject to the ISO at the time such ISO is granted, and such ISO shall
not be exercisable after five years after the date on which it was granted.
Each Stock Option shall be evidenced by a written agreement ("Option
Agreement") containing such terms and provisions as the Committee may
determine, subject to the provisions of this Plan.


6.  SHARES OF COMMON STOCK SUBJECT TO THE PLAN

         6.1.  MAXIMUM NUMBER.  The maximum aggregate number of shares of
Common Stock that may be made subject to Stock Options shall be 850,000
authorized but unissued shares.  The aggregate Fair Market Value (determined as
of the time the ISO is granted) of the stock as to all ISOs granted to an
individual which may first become exercisable in a particular calendar year may
not exceed $100,000.  If any shares of Common Stock subject to Stock Options
are not purchased or otherwise paid for before such Stock Options expire, such
shares may again be made subject to Stock Options.

         6.2.  CAPITAL CHANGES.  In the event any changes are made to the
shares of Common Stock (whether by reason of merger, consolidation,
reorganization, recapitalization, stock dividend, stock split, combination of
shares, exchange of shares, change in corporate structure or otherwise),
appropriate adjustments shall be made in:  (i) the number of shares of Common
Stock theretofore made subject to Stock Options, and in the purchase price of
said shares; and (ii) the aggregate number of shares which may be made subject
to Stock Options.  If any of the foregoing adjustments shall result in a
fractional share, the fraction shall be disregarded, and the Company shall have
no obligation to make any cash or other payment with respect to such a
fractional share.

7.  EXERCISE OF STOCK OPTIONS

         7.1  TIME OF EXERCISE.  Subject to the provisions of the Plan,
including without limitation Section 7.3, the Committee, in its discretion,
shall determine the time when a Stock Option, or a portion of a Stock Option,
shall become exercisable, and the time when a Stock Option, or a portion of a
Stock Option, shall expire.  Such time or times shall be set forth in the
Option Agreement evidencing such Stock Options.  A Stock Option shall expire,
to the extent not exercised, no later than the tenth anniversary of the date on
which it was granted.  The Committee may accelerate the vesting of any
Participant's Stock Option by giving written notice to the Participant.  Upon
receipt of such notice, the Participant and the Company shall amend the Option
Agreement to reflect the new vesting schedule.  The acceleration of the
exercise period of a Stock Option shall not affect the expiration date of that
Stock Option.

         7.2  EXCHANGE OF OUTSTANDING STOCK.  The Committee, in its sole
discretion, may permit a Participant to surrender to the Company shares of the
Common Stock previously acquired by the Participant as part of full payment for
the exercise of a Stock Option.  Such surrendered shares shall be valued at
their Fair Market Value on the date of exercise.  Unless otherwise determined
by the Committee, any such shares surrendered by the Participant shall have
been held by him for at least six months prior to surrender.

         7.3.  USE OF PROMISSORY NOTE; EXERCISE LOANS.  The Committee may, in
its sole discretion, impose terms and conditions, including conditions relating
to the manner and timing of payments, on the exercise of Stock Options.  Such
terms and conditions may include, but are not limited to, permitting a
Participant to deliver to the Company his





1990 Stock Option Plan          Confidential                              Page 3

<PAGE>   4


promissory note as full or partial payment for the exercise of a Stock Options;
provided that, with respect to any promissory note given as payment or partial
payment for the exercise of an ISO, all terms of such note shall be determined
at the time a Stock Option is granted and set forth in the Option Agreement.
The Committee, in its sole discretion, may authorize the Company to make a loan
to a Participant in connection with the exercise of Stock Options, or authorize
the Company to arrange or guarantee loans to a Participant by a third party.

         7.4.  STOCK RESTRICTION AGREEMENT.  The Committee may provide that a
share of Common Stock issuable upon exercise of a Stock Options shall, under
certain conditions, be subject to restrictions whereby the Company has a right
of first refusal with respect to such share or a right or obligation to
repurchase all or a portion of such shares, which restrictions may survive a
Participant's term of employment with the Company.  The acceleration of time or
times at which the option becomes exercisable may be conditioned upon the
Participant's agreement to such restrictions.

         7.5.  TERMINATION OF EMPLOYMENT BEFORE EXERCISE.  If a Participant's
employment with the Company or a Participating Subsidiary shall terminate for
any reason other than the Participant's death or disability, any Stock Options
then held by the Participant, to the extent then exercisable under the
applicable Option Agreement(s), shall remain exercisable after the termination
of his employment for a period of three months (but not later than the
specified expiration date).  If the Participant's employment is terminated
because the Participant is disabled within the meaning of Section 22(e)(3) of
the Code, any Stock Option then held by the Participant, to the extent then
exercisable under the applicable Option Agreement(s), shall remain exercisable
after the termination of his employment for a period of twelve months (but not
later than the specified expiration date).  If the Participant dies while
employed by the Company or a Participating Subsidiary, or during the
three-month or twelve-month periods referred to above, his Stock Options may be
exercised to the extent that they were exercisable on the date of his death or
cessation of his employment, whichever occurred first, by his estate, or duly
appointed representative, or beneficiary who acquires the Stock Options by will
or by the laws of descent and distribution, but no further installments of his
Stock Options will become exercisable and each of his Stock Options shall
terminate on the first anniversary of the date of his death (but not later than
the specified expiration dates).  If a Stock Option is not exercised during the
applicable period, it shall be deemed to have been forfeited and of no further
force or effect.

         7.6.  DISPOSITION OF FORFEITED STOCK OPTIONS.  Any shares of Common
Stock subject to Stock Options forfeited by a Participant shall not thereafter
be eligible for purchase by the Participant, but may be made subject to Stock
Options granted to other Participants.

         7.7  GRANT OF SUPPLEMENTAL BONUSES.  The Committee, either at the time
of grant or at any time prior to exercise of any Stock Options or Stock
Appreciation Right, may provide for a Supplemental Bonus from the Company or
Participating Subsidiary in connection with a specified number of shares of
Common Stock then purchasable, or which may become purchasable, under a Stock
Option, or a specified number of Stock Appreciation Rights which may be or
become exercisable.  Such Supplemental Bonus shall be payable upon the exercise
of the NSO or Stock Appreciation Right with regard to which such Supplemental
Bonus was granted; provided, that if the Participant is subject to Section
16(b) of the Securities Exchange Act of 1934, as amended, the Committee may
provide that such Supplemental Bonus will be calculated and paid six months
after such exercise.  A Supplemental Bonus shall not exceed the amount
necessary to reimburse the Participant for the income tax liability incurred by
him upon the exercise of the Stock Option or upon the exercise of such Stock
Appreciation Right, calculated using the maximum combined federal and
applicable state income tax rates then in effect and taking into account the
tax liability arising from the Participant's receipt of the Supplemental Bonus.
The Company may, in its discretion, elect to pay any part or all of the
Supplemental Bonus in:  (i) cash; (ii) shares of Common Stock; or (iii) any
combination of cash and shares of Common Stock.  The provisions of Section 8.3
shall apply to the giving of notice, the determination of the number of shares
to be delivered, and the time for delivering shares.  In applying Section 8.3,
the Supplemental Bonus shall be treated as if it were a Stock Appreciation
Right that the Participant exercised on the day the Supplemental Bonus became
payable.  Shares of Common Stock issued pursuant to this Section 7.7 shall not
be deemed to have been issued upon the exercise of a Stock Option for purposes
of the limitations imposed by Section 6.1 of the Plan.

8.  STOCK APPRECIATION RIGHTS

         8.1  GRANT OF STOCK APPRECIATION RIGHTS.  The Committee may, from time
to time, grant Stock Appreciation Rights to a Participant with respect to not
more than the number of shares of Common Stock which are or may become,
purchasable under any Stock Options held by the Participant.  The Committee
may, in its sole discretion, specify the terms and conditions of such rights,
including without limitation the time period or time periods during which such
rights may be exercised and the date or dates upon which such rights shall
expire and become void and unexercisable; provided, however, that in no event
shall such rights expire and become void and unexercisable later than the time
when the related Stock Option is exercised, expires or terminates.  Each
Participant to whom Stock Appreciation Rights are granted shall be given
written notice advising him of the grant of such rights and specifying the
terms and conditions of the rights, which shall be subject to all the
provisions of this Plan.

         8.2.  EXERCISE OF STOCK APPRECIATION RIGHTS.  Subject to Section 8.3,
and in lieu of purchasing shares of Common Stock upon the exercise of a Stock
Option held by him, a Participant may elect to exercise the Stock Appreciation
Rights, if any, he has been granted and receive payment of the Redemption Value
of all or a portion of the number of shares of Common Stock subject to such
Stock Option with respect to which he has been granted Stock Appreciation
Rights; provided, however, that the Stock Appreciation Rights may be exercised
only when the Fair Market Value exceeds the exercise price of the Stock Option.
A Participant shall exercise his Stock Appreciation Rights by delivering a
written notice to the Committee specifying the number of shares with respect to
which he exercises Stock Appreciation Rights and agreeing to surrender the
right to purchase an equivalent number of shares of Common Stock subject to his
Stock Options.  If a Participant exercises Stock Appreciation Rights, payment
of his Stock Appreciation Rights shall be made in accordance with Section 8.3
on or before the 90th day after the date of exercise of the Stock Appreciation
Rights.

         8.3.  FORM OF PAYMENT.  If a Participant elects to exercise Stock
Appreciation Rights as provided in Section 8.2, the Committee may, in its
absolute discretion, elect to pay any part or all of the Redemption Value of
the shares with respect to which the Participant has exercised Stock
Appreciation Rights in:  (i) cash; (ii) shares of Common Stock; or (iii) any
combination of cash and shares of Common Stock.  The Committee's election
pursuant to this Section 8.3 shall be made by giving written notice to the
Participant within said 90-day period, which notice shall specify the portion
which the Committee elects to pay in cash, shares of Common Stock or a
combination thereof.  In the event any portion is to be paid in shares of
Common Stock, the number of shares to be delivered shall be determined by
dividing the amount which the Committee elects to pay in shares of Common Stock
by the Fair Market Value of one share of Common Stock on the date of exercise
of the Stock Appreciation Rights.  Any fractional share resulting from any such
calculation shall be disregarded.  Said shares, together with any cash payable
to the Participant, shall be delivered within said 90-day period.


9.  NO CONTRACT OF EMPLOYMENT

Nothing in this Plan shall confer upon the Participant the right to continue in
the employ of the Company, or any Participating Subsidiary, nor shall it
interfere in any way with the right of the Company, or any such Participating
Subsidiary, to discharge the Participant at any time for any reason whatsoever,
with or without cause.  Nothing in this Article 9 shall affect any rights or
obligations of the Company or any Participant under any written contract of
employment.

10.  NO RIGHTS AS A STOCKHOLDER

A Participant shall have no rights as a stockholder with respect to any shares
of Common Stock subject to a Stock Option.  Except as provided in Section 6.2,
no adjustment shall be made in the number of shares of Common Stock issued to a
Participant, or in any other rights of the Participant upon exercise of a Stock
Option by reason of any dividend, distribution or other right granted to
stockholders for which the record date is prior to the date of exercise of the
Participant's Stock Option.





1990 Stock Option Plan          Confidential                              Page 5

<PAGE>   6


11.  ASSIGNABILITY

No Stock Option, Stock Appreciation Right or Supplemental Bonus right granted
under this Plan, nor any other rights acquired by Participant under this Plan,
shall be assignable or transferable by a Participant, other than by will or the
laws of descent and distribution, and are exercisable during his lifetime, only
by him.  Notwithstanding the preceding sentence, the Committee may, in its sole
discretion, permit the assignment or transfer of an NSO and the exercise
thereof by a person other than a Participant, on such terms and conditions as
the Committee in its sole discretion may determine.  Any such terms shall be
determined at the time the NSO is granted, and shall be set forth in the Option
Agreement.  In the event of his death, the Stock Option or any Stock
Appreciation Right or Supplemental Bonus right may be exercised by the Personal
Representative of the Participant's estate or, if no Personal Representative
has been appointed, by the successor or successors in interest determined under
the Participant's will or under the applicable laws of descent and
distribution.

12.  MERGER OR LIQUIDATION OF THE COMPANY

         12.1  If within the duration of a stock option there shall be a
corporate merger, consolidation, acquisition of assets, or other reorganization
and if such transaction shall affect the Common Stock, the Participant shall
thereafter be entitled to receive upon the exercise of his Stock Option those
shares or securities that he would have received had the Stock Option been
exercised prior to such transaction and had the Participant been a stockholder
of the Company with respect to such shares.

         12.2  If the Company or its stockholders enter into an agreement to
dispose of all, or substantially all, of the assets or outstanding capital
stock of the Company by means of a sale or liquidation, or a merger or
reorganization in which the Company is not the surviving corporation, the
vesting schedule of all Stock Options shall be accelerated so that all Stock
Options outstanding under the Plan as of the day before the consummation of
such sale, liquidation, merger or reorganization, to the extent not exercised,
shall for all purposes under this Plan become exercisable as of such date to
the extent they would otherwise be exercisable ten (10) years after such date,
unless the Board, with the consent of certain Participants, shall have
prescribed other terms and conditions to the exercise of the Stock Options held
by said consenting Participants.

13.  AMENDMENT

The Board of Directors may from time to time alter, amend, suspend or
discontinue the Plan, including, where applicable, any modifications or
amendments as it shall deem advisable in order that ISOs will be classified as
incentive stock options under the Code, or in order to conform to any
regulation or to any change in any law or regulation applicable thereto;
provided, however, that no such action shall adversely affect the rights and
obligations with respect to Stock Options at any time outstanding under the
Plan; and provided further that no such action shall, without the approval of
the stockholders of the Company, (i) increase the maximum number of shares of
Common Stock that may be made subject to Stock Options (unless necessary to
effect the adjustments required by Section 6.2), (ii) materially increase the
benefits accruing to Participants under the Plan, or (iii) materially modify
the requirements as to eligibility for participation in the Plan.

14.  REGISTRATION OF OPTIONED SHARES

The Stock Options shall not be exercisable unless the purchase of such optioned
shares is pursuant to an applicable effective registration statement under the
Securities Act of 1933, as amended, or unless, in the opinion of counsel to the
Company, the proposed purchase of such optioned shares would be exempt from the
registration requirements of the Securities Act of 1933, as amended, and from
the registration or qualification requirements of applicable state securities
laws.

15.  WITHHOLDING TAXES

The Company or Participating Subsidiary may take such steps as it may deem
necessary or appropriate for the withholding of any taxes which the Company or
the Participating Subsidiary is required by any law or regulation of any
governmental authority, whether federal, state or local, domestic or foreign to
withhold in connection with any Stock Options, Stock Appreciation Rights or
Supplemental Bonus, including, but not limited to, the withholding of all or
any





1990 Stock Option Plan          Confidential                              Page 6

<PAGE>   7


portion of any payment issued upon the exercise of any Stock Option or Stock
Appreciation Rights or upon payment of any Supplemental Bonus, until the
Participant reimburses the Company or Participating Subsidiary for the amount
the Company or Participating Subsidiary is required to withhold with respect to
such taxes, or canceling any portion of such payment or issuance in an amount
sufficient to reimburse itself for the amount it is required to so withhold.

16.  BROKERAGE ARRANGEMENTS

The Committee, in its discretion, may enter into arrangements with one or more
banks, brokers, or other financial institutions to facilitate the disposition
of shares acquired upon exercise of Stock Options, Stock Appreciation Rights or
Supplemental Bonuses, including, without limitation, arrangements for the
simultaneous exercise of Stock Options, Stock Appreciation Rights or
Supplemental Bonuses, and the sale of shares acquired upon exercise.

17.  NONEXCLUSIVITY OF THE PLAN

Neither the adoption of the Plan by the Board of Directors nor the submission
of the Plan to stockholders of the Company for approval shall be construed as
creating any limitations on the power or authority of the Board of Directors to
adopt such other or additional incentive or other compensation arrangements of
whatever nature as the Board of Directors may deem necessary or desirable or
preclude or limit the continuation of any other plan, practice or arrangement
for the payment of compensation or fringe benefits to employees generally, or
to any class or group of employees, which the Company or any Subsidiary now has
lawfully put into effect, including, without limitation, any retirement,
pension, savings and stock purchase plan, insurance, death and disability
benefits and executive short-term incentive plans.

18.  EFFECTIVE DATE

This Plan was adopted by the Board of Directors and became effective on April
15, 1990 and was approved by the Company's stockholders on April 17, 1990.  No
Stock Options shall be granted subsequent to ten years after the effective date
of the Plan.  Stock Options outstanding subsequent to ten years after the
effective date of the Plan shall continue to be governed by the provisions of
the Plan.

3.1.     GENERAL

The Parties agree to jointly develop and in good faith negotiate, by September
1, 1994, a detailed Exhibit A, "Scope of Work" (SOW), to replace the SOW
outline presently included as Exhibit A.  The SOW will be a complete and
detailed description of all the work SCC will perform for Ameritech hereunder
for the fees specified herein.  The SOW will include all those "Parts" listed
on the Table of Contents page of Exhibit A, "Scope of Work".  The SOW outline
and content presently set forth in Exhibit A will be followed by the Parties
unless they later mutually agree not to.  During the development of the SOW,
both Parties recognize that through the process, and in light of the experience
gained in the process, there may be changes or modifications requested to be
made to this Agreement by either Party.  Such requests shall be considered and
negotiated in good faith by both Parties and incorporated, if mutually agreed
to, in writing into this Agreement.

3.2.     PROJECT IMPLEMENTATION PLAN

An Implementation Plan shall be mutually developed and agreed to by both
Parties by September 1, 1994 and incorporated into this Agreement as part of
Exhibit A. The fully detailed Implementation Plan shall define the process for
conversion of data handling services to SCC under the terms of this Agreement,
the specific tasks, responsibilities, and performance dates of each party, the
specific services to be provided, and the performance requirements and
objectives for the provisioning of the 9-1-1 Services, and remedies and
consequences for non-performance according to the Performance Metrics to be
contained in Exhibit A.  SCC is responsible for demonstrating that the 9-1-1
Services meet the acceptance criteria set forth in Exhibit A, the Scope of
Work.

Exhibit A shall also contain the Ameritech performance requirements and

3.3.     PROJECT MANAGEMENT AND OTHER PERSONNEL

SCC and Ameritech shall each designate an individual, the "Project Manager",
who shall act as the primary interface between the Parties. The Project
Managers shall be responsible for insuring the continuity of communications
between the Parties as the Project proceeds.

SCC will provide office facilities and working space for an Ameritech employee,
the "Database Manager", designated to be on site at SCC's corporate offices in
Boulder, Colorado to assist with the Project.  All Database Manager expenses,
except for the associated facilities and administrative costs, shall be paid by
Ameritech.  The Ameritech Database Manager shall remain on site as long as it
is mutually determined to be necessary.

On a mutually agreed to periodic basis the Project Managers shall meet in order
for SCC and Ameritech to inform each other of the status of the Project and its
respective tasks and responsibilities.  Such meetings shall include each
Party's Project Manager as well as appropriate additional personnel such as
Ameritech's Database Manager, and each Party shall provide a written status
report on the work being performed by it.  Alternatively, Ameritech may elect
to forego all or some of such meetings and may direct SCC to provide it with
periodic written reports on the status of the Scope of Work being undertaken by
SCC under this Agreement.  The specific Project responsibilities of SCC and
Ameritech are set forth in Exhibit A.

SCC and Ameritech recognize the need to provide and maintain qualified
personnel involved in all aspects of the 9-1-1 Services described in this
Agreement.  In order to achieve continued high quality services through its
personnel, SCC shall establish and implement a mutually agreed to plan to
certify its personnel.  SCC is responsible for the costs associated with the
certification of its employees.

All requests for additional services, conversion of additional records,
training, enhancements, and New Services shall be coordinated through the
Project Managers and handled in accordance with Article 17, "Add-on Orders".

SCC and Ameritech shall mutually develop, as part of the SOW, a policy
statement describing a Code of Conduct to be endorsed in writing by all SCC
personnel involved in providing 9-1-1 Services under this Agreement.

3.4.     TRAINING

Any training required as part of the SOW shall be indicated in the SOW.

In addition to the training set forth in the SOW, from time to time, at
Ameritech's request, SCC shall provide training classes at sites and at times
agreed upon by the Parties.  Such additional training classes shall be billed
to Ameritech at SCC's published rates as shown in Exhibit B, Personnel Rates
minus any discounts to which Ameritech is entitled under this Agreement or
otherwise.  In addition, Ameritech shall be responsible for all reasonable
expenses incurred by SCC for travel, meals, and lodging in connection with
rendering training services in accordance with this Section.  Airplane fares
shall not exceed the coach rates then prevailing, and SCC shall use its best
efforts to plan its travel in advance in order to maximize its use of air
travel discounts.  SCC also shall use its best efforts to obtain lodging and
other travel-related discounts.  SCC shall provide Ameritech with invoices
detailing any such expenses.

All training provided by SCC shall include written course materials that may be
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.

Ameritech may cancel a training course scheduled by SCC upon fourteen (14) days
prior written notice to SCC.  For cancellations with less than fourteen (14)
days prior written notice, Ameritech shall be liable to SCC for all reasonable
expenses incurred by SCC in preparation for the course that are not otherwise
recoverable by SCC.

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




3.5.     NETWORK

SCC shall design, develop, purchase, own or lease, implement, manage, maintain
and monitor all the Network hardware and software components further defined in
Exhibit A so the Network can be demonstrated to meet the performance
requirements as mutually established in Exhibit A.  SCC acknowledges and agrees
that the participation of Ameritech personnel in all phases of the Network
implementation is necessary to the ongoing success of the provision of 9-1-1
Services.

3.6.     SUPPORT SERVICES

SCC shall provide "Support Services" as described in Exhibit A to maintain the
Performance Metrics mutually agreed to and contained in Exhibit A.

3.7.     SYSTEM EFFICIENCY

SCC is committed to improving and exceeding the standards and requirements of
this Agreement in the provision of 9-1-1 Services.  This includes improvements
in the automation procedures, software products, hardware products, personnel
training and qualifications, and all other services.  Therefore, performance
and efficiency of the "System" will be maintained and periodically improved by
SCC without charge to Ameritech.  Such changes in the provision of Base
Services shall be considered usual and customary and not New Services.  The
System is described in Exhibit A.

3.8.     REGIONAL UNIFORMITY

The 9-1-1 Services and Support Services shall be provided under regionally
consistent terms and shall not be state- specific unless it is legally mandated
by the state or other legally governing body.

                         4.   JOINT RESPONSIBILITIES

4.1.     INTERNSHIP EXCHANGE PROGRAM

Ameritech and SCC agree that the success of this Agreement is dependent upon
the knowledge of the organization and operations of the other Party.  To
optimize the provisioning of 9-1-1 Services, the Parties shall develop a
program designed to strengthen the ability to create, acquire, and transfer
knowledge, the "Internship Exchange Program".  An individual (the "Intern")
shall be selected from each Party to relocate and participate in the other
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.

4.2.     ELECTRONIC EXCHANGE

To the extent possible, and as it becomes available, both Parties will use and
implement automation procedures to facilitate communication, coordination,
maintenance, and management of the 9-1-1 Services.

                       5.   AMERITECH RESPONSIBILITIES

Ameritech's responsibilities are those stated in this Agreement and the
Exhibits hereto.  As the mutually agreed to SOW is completed, specific
responsibilities shall be further defined.

                                  6.   TERM

Unless earlier terminated or cancelled in accordance with Section 19,
"Termination/Cancellation", the term of this Agreement shall begin upon the
Effective Date as first stated herein and continue for [           ] following
expiration of the "Option Period" set forth in Section 8 below.    If either
Party terminates this Agreement, or Ameritech cancels this Agreement, according
to the provisions of Section 19, then both Parties agree to participate in the
orderly shutdown and transition of products and services as provided for in
Exhibit A, the De-Implementation Plan.  Following this initial [            ]
term, the Agreement shall automatically renew for continuous [             ]
unless terminated at the end of a renewal term upon no less than 180 days
advance written notification by the terminating Party.

                            7.   PRICE AND PAYMENT

9-1-1 Service charges shall consist of an initial non-recurring engineering set
up charge ("NRE") followed by monthly invoices for recurring charges based on
per record fees.  The NRE charge of [          ] shall be paid upon the date of
execution by Ameritech of this Agreement.  All 9-1-1 Service charges, volume
commitments, and regularly scheduled audit procedures are outlined in Exhibit
B.  Recurring charges for the 9-1-1 Services provided by SCC shall be on a per
record basis in committed to incremental blocks ("Thresholds") as outlined in
Exhibit B.  Invoices for the recurring 9-1-1 Services will be submitted to
Ameritech monthly, on or about the first of the month (for the month being
billed for) and will be paid by Ameritech within 30 days of their receipt.
Other than for mutually agreed to exceptions and the addition of New Services
to expand Base Services, there will be no other initial NRE charges associated
with the addition of records.

The Monthly Base Service Charge per Base Record outlined in Exhibit B is based
on a [             ] Agreement term.  

Services that are provided on a time-and-materials or other non-fixed-fee basis
shall be billed in arrears, after provision of the services, and Ameritech
shall pay any such charges within thirty (30) days of receipt of an invoice
that describes such charges.  SCC's current published rates are shown in
Exhibit B, Personnel Rates, with the applicable discounts Ameritech is entitled
to hereunder.

If services are provided on a time-and-materials basis, SCC shall specify a
not-to-exceed billable amount.  Billings for services shall not exceed this
amount without Ameritech's prior written approval.

                             8.   PURCHASE OPTION

For a period commencing upon the Effective Date and continuing for ninety (90)
days after Ameritech's Acceptance of 9-1- 1 Services in Ohio ("Option Period"),
Ameritech shall have the option, at no additional fee, of not buying 9-1-1
Services from SCC and, instead, purchasing software licenses, developed
software and software maintenance services from SCC in accordance with the
prices and other terms and conditions set forth in Exhibit C, the "Purchase
Option" (except that the acquisition timeframes set forth in Exhibit C shall be
modified as appropriate).  Ameritech may also purchase equipment from SCC at
prices, and other terms and conditions mutually agreed upon by the Parties at
such time.  Notwithstanding anything to the contrary in Exhibit C, or elsewhere
in this Agreement, Ameritech shall have the right to exercise this Purchase
Option on a state-by-state basis or for the entire Ameritech Region.  The
state-by-state purchase price during the Option Period will be determined on a
pro-rated basis.  If Ameritech elects to exercise its Purchase Option for the
entire Ameritech Region, it shall be entitled to a full credit from SCC of all
unexpended NRE amounts which shall be used, as directed by Ameritech, to credit
subsequent SCC invoices to Ameritech for Ameritech's purchase of said software
licenses, developed software and software maintenance services.  If Ameritech
elects to exercise its Purchase Option on a state-by-state basis, it shall be
entitled to a partial refund of the NRE as set forth in Exhibit B, associated
with each particular state the Purchase Option is exercised for, which shall be
used, as directed by Ameritech, to credit subsequent SCC invoices 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

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

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.

acts of the government, fires, floods, epidemics, quarantine restrictions,
strikes, labor disputes (including collective bargaining issues), work

                        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 accomodations 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

                                                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

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

alternative providers to facilitate the saving of lives and property.

     its own information of like importance but not less than a reasonable
     degree of care. Notwithstanding any other provisions of this Article,
     Confidential Information may be disclosed as may be required by law,
     regulation or court or agency order or demand, after prompt prior

     hereafter owned or controlled by the other party. Upon termination,
     cancellation or expiration of this Agreement for any reason or upon request
     of the disclosing party, all Confidential Information, together with any
     copies of same as may be authorized herein, shall be returned to the
     disclosing party or certified destroyed by the receiving party.

     17.2. If a preliminary or final judgment shall be obtained against

     parties shall share equally the fees and expenses of the arbitrator. The

1.01           An Affiliated Company is defined herein as BellSouth corporation
               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 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

<PAGE>   5
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.

               Letter Purchase Orders.  Said Orders, at a minimum, shall
               specify the information outlined below:


2.04.1         A reference to this Agreement.

               and Seller shall each designate an individual, (the "Project
               Manager"), who will act as the primary interface between the
               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
               include the address and telephone number of each Project
               Manager.
               
2.04.5         An enumeration of any items of expense authorized for
               reimbursement to Seller, as well as the basis for such
               reimbursement.

               Purchase Order should state the maximum total expenditure
               authorized, which is understood to mean (1) a dollar amount or
               time limit beyond which Seller may not invoice for consultant
               and/or professional services under the specific Letter Purchase
               Order, and (2) a dollar amount or time limit beyond which Seller
               is not required to expend effort or provide consultant and/or
               professional services under a specific Letter Purchase Order

               feasible, at the Buyer's option, the hourly, daily or unit rate
               of Seller may be substituted.

               Emergency Services to be performed.

2.04.8         Invoicing instructions.

               Letter Purchase order shall be stated in the Letter Purchase
               Order.  The completion of Emergency Services identified in each
               Letter Purchase Order which is being terminated shall also be
               stated in the Letter Purchase Order.


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

               such taxing authority.
               
SECTION 14.  ASSIGNMENT BY SELLER

14.01          Except for Seller's assignment to a third party acquiring all or
               substantially all of Seller's assets or stock, or by merger of
               Seller and a third party, Seller shall not assign or otherwise
               delegate any work to be performed by it under this Agreement, in
               whole or in part, or any of its right, interest or obligation
               hereunder without first obtaining Buyer's prior written consent,
               which consent shall not be unreasonably withheld.  Seller shall
               deliver to Buyer written notice of Seller's intent to assign, at
               least thirty (30) days prior to assignment.  Any assignment not
               consented to by Buyer shall be deemed void; except that Seller
               may assign its rights to receive monies pursuant to this
               Agreement upon delivering the required notice to Buyer, without
               Buyer's prior consent.  No assignment of monies due or to become
               due to Seller shall be made by Seller if such assignment
               attempts to transfer to the assignee any other rights or
               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.

SECTION 15.  ASSIGNMENT BY BUYER

15.01          Buyer shall have the right to assign this Agreement and to
               assign its rights and delegate its duties under this Agreement
               either in whole or in part, at any time and without Seller's
               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
               neither affect nor diminish any rights or duties that Seller or
               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
               and discharged, to the extent of the assignment, from all
               further duties under this Agreement, except with respect to

               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.

               discretion determine the quality and acceptability of the
               Emergency Services performed pursuant to this Agreement.
               
               


SECTION 19.  NON-EXCLUSIVE RIGHTS

               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
               determine, at Buyer's sole discretion, the extent to which

               Companies or language from which the connection of said Marks
               therewith may be inferred or implied, or mentioning or
               implying the names of any personnel of BellSouth Corporation
               and/or any of its Affiliated Companies, and Seller further

               Such correcting activities shall commence immediately and be
               completed as quickly as is reasonably possible.

23.02          Seller shall conduct, at Seller's expense, background
               investigations on Seller's personnel performing work on

               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

               defend, and hold the other party harmless against any wrongful

               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.

               A.
               
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           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.

               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.

               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

               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)").
               If any such Condition occurs, the party delayed or unable to
               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

               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

               Purchase Order and may not be modified or amended other than
               by a written instrument executed by both parties.  With the
               exception of those pre-printed provisions included as a part

technology.
 
                                   2. PROJECT
 
2.1  SCOPE OF WORK (EXHIBIT A).
 
     The Scope of Work set forth in Exhibit A constitutes a complete and
detailed description of SCC's obligations to perform the Services to be
performed in connection with the Project, which shall be performed exclusively
by SCC in Ameritech's Wireline Regions, and non-exclusively in all other AMCI
Regions, subject to AMCI's rights expressly stated herein, and which shall apply
to the entire AMCI Region, to all Qualified PSAPs therein, and to all of AMCI's
Subscribers. SCC acknowledges that its Services represent a portion of combined
effort on the part of other critical third party vendors who themselves, along
with SCC, are participating in an integrated effort to deploy AMCI's Phase I
E9-1-1 wireless service; and in this regard, SCC will reasonably cooperate with
such other vendors as set forth in Exhibit A. AMCI will timely perform its
obligations as set forth in Exhibit A.
 
  2.1.1  MARKET AREA SURVEY.
 
     SCC shall not be responsible for providing a Market Area Survey under the
terms and conditions of this Agreement. The Parties have already executed a
"Consulting Agreement" dated October 27, 1997, which is hereby ratified, which
agreement will govern the terms and conditions under which SCC will perform a
"Market Area Survey And Analysis". SCC will ensure that its work related to said
Market Area Survey And
 
                                        2
<PAGE>   5
 
Analysis will be performed in a manner consistent with the terms and conditions
of this Agreement and Exhibit A.
 
  2.1.2  SYSTEM EFFICIENCY.
 
     SCC is devoted to improving and exceeding the standards and requirements of
this Agreement in the provision of Services. This includes improvement in the
automation procedures, software products, hardware products, personnel training
and qualifications, and all other services. Therefore, performance and
efficiency of the system for delivery of the Services will be maintained and
periodically improved by SCC without charge to AMCI. Such changes in the
provision of Services shall be considered usual and customary and not New
Services. The system for delivery of the Services is described in Exhibit A.
 
  2.1.3  REGIONAL UNIFORMITY.
 
     Except as may otherwise be described herein, the Services will be provided
under regionally consistent terms and shall not be state-specific unless it is
legally mandated by the state or other legally governing body.
 
2.2  CANCELLATION FEE SCHEDULE (EXHIBIT B).
 
     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.
 
2.3  MODIFICATION ORDER (EXHIBIT C).
 
     If AMCI elects to purchase from SCC New Services or Add-On Services, AMCI
will deliver to SCC a completed form substantially similar to that which is set
forth in Section 1.7 of Exhibit A. The parties will negotiate in good faith the
terms and conditions relating to the provision of such services, which shall
include at a minimum: (a) a description of the requested service; (b) a
projected date of its availability; (c) a proposed implementation schedule; (d)
the initial non-recurring charges and/or additional recurring charges associated
with the service; and (e) any other information deemed appropriate by the
Parties. Modification Orders will not be effective or binding upon the parties
unless signed by an authorized individual from AMCI who occupies a position at
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.
 
  2.5.1  TRANSITIONED SERVICES -- SUBSTITUTION FOR SCC.
 
     In AMCI's sole discretion, AMCI may elect to perform, or have its agents
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 [                ] 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 [                ] 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 four percent (4%) 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.

6.1  NON-DISCLOSURE AND SYSTEM SECURITY.
 
     The Parties each recognize and acknowledge the importance of maintaining
the security and integrity of the other Party's systems and data as well as the
confidential and proprietary nature of same, including such items as AMCI's
operating information and RF coverage areas, AMCI Results, AMCI Furnished

     During the course of this Agreement, either party may receive or have
access to confidential information of the other. "Confidential Information"
means any confidential, private, or proprietary information or data disclosed by
a Party (the "Disclosing Party") to the other Party (the "Recipient") under or
in contemplation of this Agreement which: (a) if in tangible form or other media

     Party but only to the extent of such authorization and without any
     disassembly, reverse engineering, or similar undertaking by Recipient; or
 
          (f) 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 which permits
     the Disclosing Party a reasonable opportunity to seek an appropriate
     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

                                 7. WARRANTIES
 
7.1  WARRANTY BY SCC.
 
     SCC warrants and represents to AMCI that: any support and services that SCC
provides to AMCI under this Agreement shall be provided by personnel who are
trained and skilled in the provision of such services and shall be provided in a
professional, effective and efficient manner that equals or exceeds the
then-current industry standard for such services. SCC further warrants that the
Services provided hereunder shall equal or exceed the Performance Metrics
criteria set forth in Exhibit A.
 
     EXCEPT AS PROVIDED, INCORPORATED INTO, OR REFERRED TO IN THIS AGREEMENT,
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
by or for SCC will: (1) accept date information before, during and after January
1, 2000, including but not limited to accepting date input,
 
                                       13
<PAGE>   16
 
providing date output and performing calculations on dates or portions of dates;
(2) function accurately, without disruption or abnormal ending-scenario or with
any change in the operation of such software or routing services associated with
the advent of the new century, (3) respond to two-digit year and date input in a
way that resolves the ambiguity as to century in a disclosed, defined and
predetermined manner, and (iv) store and provide output of date information in a
way that is unambiguous as to the twentieth or twenty-first century;
 
     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
material licenses, permits and other authorization necessary to own and operate
its business and to perform the obligations imposed upon it hereunder;
 
     (b) AMCI has no knowledge of any existing software viruses that would
materially impact AMCI's performance hereunder. If AMCI becomes aware of any
such viruses in its software used in connection with its performance hereunder,
it will advise SCC in writing immediately. If SCC's performance hereunder is
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.
 
                               8. INDEMNIFICATION
 
8.1 GENERAL INDEMNIFICATION.
 
     Each Party shall 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 Services under this
Agreement by the indemnifying Party. The indemnified Party shall promptly notify
the indemnifying Party of any written claim, loss or demand for which the
indemnifying Party is responsible under this Section
 
8.2 INTELLECTUAL PROPERTY INDEMNIFICATION.
 
     SCC shall defend, at its sole cost and expense, any claim or action of any
kind against AMCI for alleged violation, infringement or misappropriation of any
patent, copyright, trade secret or other intellectual property right based on
the use of SCC products or services under this Agreement. SCC shall have the
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, AMCI, at its own expense, shall have the right
 
                                       14
<PAGE>   17
 
to participate in the defense of any such suit or proceeding through counsel of
its choosing. SCC shall indemnify and hold harmless AMCI and its officers,
directors, employees, and agents and their successors and assigns against and
from any and all losses, liabilities, damages, claims, demands and expenses
(including, without limitation, reasonable attorneys' fees) arising out of or
related to any such claim or action.
 
     If any SCC product used to provide the 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 AMCI is lawful;
 
          (ii) modify such product so that its use by SCC for AMCI is lawful
     (provided that such modification does not adversely affect the Services
     provided); or
 
          (iii) replace such product, at no charge to AMCI, with equally
     suitable, compatible and functionally equivalent products that lawfully may
     be used by SCC for AMCI.
 
                           9. LIMITATION OF LIABILITY
 
     EXCEPT WITH RESPECT TO SCC'S OBLIGATION TO INDEMNIFY AMCI IN CONNECTION
WITH THIRD PARTY CLAIMS AND IN CONNECTION WITH INTELLECTUAL PROPERTY
INFRINGEMENT AS SET FORTH IN SECTION 8 HEREIN ABOVE, NEITHER PARTY SHALL BE
LIABLE TO THE OTHER FOR ANY INDIRECT, SPECIAL, CONSEQUENTIAL, INCIDENTAL, OR
PUNITIVE DAMAGES, WHETHER BASED UPON LOST GOODWILL, LOST PROFITS, LOSS OF USE OR
PERFORMANCE OF ANY PRODUCTS, SERVICES, OR OTHER PROPERTY, LOSS OR IMPAIRMENT OF
DATA OR SOFTWARE, OR OTHERWISE, AND WHETHER ARISING OUT OF BREACH OF EXPRESS OR
IMPLIED WARRANTY, CONTRACT (INCLUDING THE FURNISHING, PERFORMANCE, OR USE OF ANY
HARDWARE, SOFTWARE OR OTHER PRODUCTS, MATERIALS, OR SERVICES PROVIDED PURSUANT
TO THIS AGREEMENT OR THE PERFORMANCE OR NONPERFORMANCE OF OBLIGATIONS UNDERTAKEN
IN THIS AGREEMENT), TORT, (INCLUDING NEGLIGENCE), STRICT PRODUCT LIABILITY OR
OTHERWISE, REGARDLESS OF WHETHER SUCH PARTY HAS BEEN NOTIFIED OF THE POSSIBILITY
OF SUCH DAMAGES OR IF SUCH DAMAGES COULD HAVE BEEN REASONABLY FORESEEN.
 
     To the extent not otherwise governed by federal, state or local law, and
except with respect to SCC's obligation to indemnify AMCI in connection with
third party claims and in connection with intellectual property infringement set
forth in section 8 herein above, SCC's entire liability to AMCI shall be limited
to that which is directly related to its alleged negligent performance or
non-performance of its obligations hereunder, and in any event shall be limited
to the payment of a sum not to exceed [                              ].
 
                                 10. INSURANCE
 
     During the Term hereof, including any extensions, SCC must maintain not
less than the same insurance coverages as that described in SCC's agreement with
Ameritech Information Systems, Inc. dated August 31, 1994. Neither SCC nor SCC's
insurer(s) shall have a claim, right of action or right of subrogation against
AMCI based on any loss or liability insured against under the foregoing
insurance. SCC's policy must be endorsed to name AMCI and its corporate
affiliates as additional insureds and state: "AMCI 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, AMCI may
procure such insurance. In such event, SCC shall promptly reimburse AMCI for any
premiums and other charges paid by AMCI for such coverage.

11.1 EXHIBITS.
 
     Exhibits A, B, C and D shall be deemed incorporated herein and an integral
part of this Agreement. Any AMCI requests for proposal, SCC's responses thereto,
marketing or sales material or any other similar documentation, as well as any
written or verbal representations concerning the Services, SCP Services, New
Services or Add-On Services are specifically excluded from this Agreement and
shall have no relevance, value or binding effect hereon.
 
11.2 ELECTRONIC EXCHANGE.
 
     To the extent possible, as determined by subsequent, mutual agreement of
the Parties, the Parties will endeavor to use and implement automation
procedures, such as electronic data interchange (EDI), electronic mail and "Web
pages", to facilitate communication, coordination, maintenance, and management
of the Services. If implemented, each Party will be responsible for its
respective costs associated with such exchange.
 
11.3 STAFFING LEVEL.
 
     SCC will, at all times relevant hereto, maintain a sufficient number of
employees in its discretion to adequately perform the Services, and if

     SCC shall not prepare or distribute any news releases, articles, brochures,
speeches, Advertisements or other informational releases concerning this

mark (or any variation thereof) without the prior written consent of AMCI, which
shall not be unreasonably withheld.
 
11.5 ASSIGNMENT AND DELEGATION.
 
     Neither party shall assign any right or obligation under this Agreement
without the other party's prior written consent. Any attempted assignment shall
be void, except that either party may assign monies due or to become due to it,
provided that (a) the assigning party gives the other party at least ten (10)
days prior written notice of such assignment and (b) such assignment does not
impose upon the other party obligations to the assignee other than the payment
of such monies.
 
     Notwithstanding the foregoing, AMCI may assign this Agreement, in whole or
in part, to any of its Affiliates. SCC may assign this Agreement, in whole or in
part, to any of its Affiliates; provided, however, that SCC may not assign this
Agreement to any entity that directly or indirectly through that entity itself
or one of its Affiliates provides two-way cellular voice communication services
or other wireless communication or data services. With respect to assignments by
either Party, any purported assignment may be rejected by the non-assigning
Party, and therefore deemed void, if such Party determines that the assignee is
incapable of substantially performing the assigning Party's obligations
hereunder. Upon such permitted assignment and written assumption of liability
thereto by the assignee, the assignor shall be discharged of any liability 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,
war, acts of the government (where neither Party is itself a governmental body),
fires, floods, epidemics, quarantine restrictions, civil disobedience, criminal
acts by a third party, strikes, labor disputes (including collective bargaining

contractors. Each Party has the sole obligation to supervise, manage, contract,
direct, procure, perform, or cause to be performed its obligations set forth in

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.
 
11.11  SUBCONTRACTING.
 
     SCC shall not subcontract any portion of the work required to be performed
as part of the Project without the prior written consent of AMCI.
 
11.12  JOINT WORK PRODUCT.

obligation is asserted. Seller represents and warrants that, except as set forth

Buyer shall not be obligated to assume any Assumed Obligation which is in
default as of the Closing Date, or any obligation relating to periods prior to

        3. PURCHASE PRICE AND TERMS OF PAYMENT.

           3.1 PURCHASE PRICE. As consideration for the sale to Buyer of the
Purchased Assets, Buyer agrees to pay to Seller the aggregate sum of [      ],
representing the net book value of the Purchased Assets as of June 30, 1997,

project losses has been increased to [      ] and all capitalized software has
been written off), and to assume the Assumed Obligations in Section 1.2 (the

"Code"), and any regulations thereunder.

        4. REPRESENTATIONS AND WARRANTIES OF THE SELLER. Except as disclosed in
the Schedules delivered concurrently herewith by reference to the specific
Section or Sections hereof to which the disclosure pertains, Seller hereby
represents and warrants to Buyer, as of the date hereof and as of the Closing
Date, as follows:

           4.1 AUTHORITY AND BINDING EFFECT. Seller has the full corporate power
and authority to execute and deliver this Agreement and each agreement
referenced herein (the "Related Agreements") to which it is a party and to
consummate the transactions contemplated by, and comply with its obligations
under, such agreements. This Agreement and the Related Agreements to which
Seller is a party, and the consummation by Seller of its obligations herein and
therein, have been duly authorized by all necessary corporate action of Seller,
including, without limitation, the approval of its shareholders in accordance
with applicable law. This Agreement and the Related Agreements have been duly
executed and delivered by the Seller and upon their execution and delivery will
be, the binding and valid agreements of the Seller. This Agreement and the
Related Agreements shall be enforceable against the Seller, in each such case in
accordance with their respective terms, except as such enforceability may be
limited by (i) bankruptcy, insolvency, moratorium or other similar laws
affecting creditors' rights generally and (ii) general principles of equity
relating to the availability of equitable remedies. No further action is
required to be taken by the Seller, nor is it necessary for the Seller to obtain
any action, approval or consent by or from any third persons, governmental or
other, to enable the Seller to enter into or perform its obligations under this
Agreement and the Related Agreements to which it is a party, except for the
consents of third parties to the assignment and assumption of the Assumed
Contracts which Seller shall use its best efforts to obtain following the
Closing (unless waived in writing by Buyer). Such consents are set forth in
Schedule 4.6 hereto.

                                       4
<PAGE>   6

           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

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,

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

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,

actions for infringement of, all Seller Rights, other than Third Party
Technology.

               (c) Schedule 4.15 contains an accurate and complete description

agreements relating thereto.

               (d) All of Seller's copyright registrations related to any and
all of Seller's copyrights are valid and in full force and effect. If the

copyrights in all 


                                       13
<PAGE>   15


CAD/RMS Products containing material copyrightable material. Consummation of the
transactions contemplated hereby will not alter or impair the validity of any
copyrights or copyright registrations.

               (e) No claims have been asserted against Seller by any person
challenging Seller's use or distribution (including manufacture, marketing
license, or sale) of any Seller Right or products utilized by Seller (including,
without limitation, the CAD/RMS Products and Third Party Technology) or

agreement relating thereto (including, without limitation, the Third Party
Licenses). There is no valid basis for any claim of the type specified in this
Section 4.15(e).

               (f) The execution, delivery and performance of this Agreement and
the consummation of the Merger and the transactions contemplated hereby and by
the other Transaction Documents will not (i) breach, violate or conflict with

party, including (i) infringement of or misappropriation of Intellectual
Property, (ii) unfair competition, (iii) defamation, (iv) contractual rights, or
(v) rights of privacy or publicity. Solely with respect to claims of

of Third Party Technology, the foregoing representations in this Section are
made to the best knowledge of Seller.

of default by Seller under, or breach or violation by Seller of, any contract,
commitment or restriction relating to any Seller Right, including any Third
Party License (each, an "Intellectual Property Contract"). No other party is in
default under or in breach or violation of, nor, to the best of Seller's
knowledge, is there any valid basis for any claim of default by any other party
under or any breach or violation by any other party of, any Intellectual
Property Contract. Each Intellectual Property Contract is valid, binding, in
full force and effect, and enforceable by Seller in accordance with its terms.
To the best knowledge of Seller, no party to any Intellectual Property Contract
intends to cancel, withdraw, modify or amend such contract.

               (k) No shareholder or employee of Seller, nor any of their
respective affiliates, has any right, title or interest in or to any Seller
Right, other than rights pertaining to Third 

                                       14

Technology obtained from the third party licensor; (ii) Seller has no
agreements, contracts or commitments that provide for the manufacture,

market any product utilizing any Seller Right under any "private label"
arrangements pursuant to which Seller is not identified as the source of such
goods. Each document or instrument identified pursuant to this Section is listed
in Schedule 4.15 and true and correct copies of such documents or instruments
have been furnished to Buyer. Except with respect to the rights of third parties
to the Third Party Technology, no third party has any right to manufacture,
reproduce, distribute, sublicense, market or exploit any works or materials of
which any of the Seller Rights are a derivative work.

               (m) Each CAD/RMS Product: (i) substantially complies with all

requirements, other than bugs or fixes required or expected in the ordinary
course of business as historically experienced in the Business; (ii) has been

their development were written, developed and created solely and exclusively by
employees of Seller without the assistance of any third party or entity.

               (o) Seller has not knowingly altered its data, or any Seller

CAD/RMS Product.

               (q) Seller has not disclosed or otherwise dealt with any aspect
of any Seller Rights, other than Third Party Technology, that would constitute a
trade secret if not injected into the public domain or if treated as secret, in
such a manner as to cause such aspect not to constitute a trade secret.

               (r) No employee of Seller is in violation of any term of any
employment contract, patent disclosure agreement or any other contract or
agreement relating to the relationship 


                                       15
<PAGE>   17

of any such employee with Seller or, to Seller's best knowledge, any other party
because of the nature of the business conducted by Seller or proposed to be
conducted by Seller. Neither the execution or delivery of any of the foregoing
agreements, nor the carrying on of Seller's business as employees by such
persons, nor the conduct of Seller's business as currently anticipated, will
conflict with or result in a breach of the terms, conditions or provisions of or
constitute a default under any contract, covenant or instrument under which any
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.

               (s) No product liability or warranty claims have been
communicated to or threatened against Seller nor, to the best of Seller's
knowledge, is there any specific situation, set of facts or occurrence that
provides a basis for such claim.

               (t) Each employee or contractor of Seller at any time engaged in

(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
under this Agreement and the Related Agreements.

           15.2 BROKER'S FEES. Each party represents and warrants that it has
not utilized the services of, and that it does not and will not have any
liability to, any broker or finder in connection with this Agreement or the
transactions contemplated hereby. The Seller jointly and severally agree to
indemnify and hold harmless Buyer, and Buyer agrees to hold harmless Seller,
against any loss, liability, damage, cost, claim or expense incurred by reason
of any brokerage commission or finder's fee alleged to be payable as a result
of, or in connection with, this Agreement or the transactions contemplated
hereby by reason of any act, omission or statement of the indemnifying party.

        16. NOTICES. All notices, requests, demands or other communications
hereunder shall be in writing and shall be deemed to have been duly given, if
delivered in person or by a nationally recognized courier service, if sent by
facsimile machine ("fax") or mailed, certified, return-receipt requested,

                                     TO THE
                        ASSET PURCHASE AGREEMENT BETWEEN
                         PRINTRAK INTERNATIONAL INC. AND
                         SCC COMMUNICATIONS CORPORATION

This Amendment One, effective December 1, 1997, amends and modifies certain
terms and conditions of the Asset Purchase Agreement ("Agreement") dated July
18, 1997, between PRINTRAK INTERNATIONAL INC. ("Printrak") and SCC
COMMUNICATIONS CORPORATION ("SCC").

     WHEREAS, Printrak and SCC have entered into the Agreement to consummate
Printrak's acquisition of the Computer Automated Dispatch ("CAD") and Records
Management System ("RMS") business unit of SCC; and

     WHEREAS, pursuant to the Agreement, Printrak acquired certain rights to
sublicense and use the Graphic Geofile Management ("GGM") products and services
as stated in Exhibit D ("Mapping Services") of the Agreement; and

     WHEREAS, the copyright and other intellectual property rights in and to the
GGM product are mutually owned by SCC and Signal Soft Corporation ("Signal
Soft"), and the right to license and sublicense same is also shared by such
parties; and

     WHEREAS, both Parties to the Agreement wish to further define and clarify
the GGM product and service rights and obligations addressed within Exhibit D of
the Agreement.

     NOW THEREFORE, in consideration of the mutual terms and conditions,
promises and covenants hereinafter set forth, Printrak and SCC agree as follows:


1.   GGM SOFTWARE APPLICATION - LICENSE RIGHTS

In addition to the sublicense rights granted to Printrak in Exhibit D of the
Agreement, the Parties agree that object code and source code for the GGM
Software Application shall be provided to Printrak employees on a "need to know"
basis. Except for the limited rights granted to Printrak herein, nothing herein
shall be deemed to have conveyed any right, title or interest, including but not
limited to copyright, in or to the GGM Product or its related intellectual
property.

1.1  SOURCE CODE RIGHTS

Printrak shall be allowed to modify and enhance Source Code. Any Printrak
modifications, enhancements or improvements to the Source Code shall be made
available by Printrak to SCC and Signal Soft within a reasonable time after the
same is available. SCC and Signal Soft shall own such modifications, enhancement
and improvements and shall be permitted hereby to utilize same for their
respective business purposes, and Printrak shall have a non-exclusive,
perpetual, paid-up license to exploit same in accordance with the terms and
conditions of the Agreement as amended hereby. Updated Source Code for the GGM
products shall be shared by Printrak, SCC and Signal Soft for the purposes of
conducting each parties' respective independent business operations.

                                                                   AMENDMENT ONE
                                                        ASSET PURCHASE AGREEMENT
                                                                    SCC/PRINTRAK
- --------------------------------------------------------------------------------



Printrak is granted the right to provide Source Code in third party escrow
accounts to Printrak's CAD and RMS customers. Any such arrangement shall occur
with the guidance of a third party escrow agent who shall utilize a written
escrow agreement in connection therewith. All third party escrow agreements
shall mandate that: (i) the escrow agent shall not release the Source Code until
sufficient evidence has been demonstrated to said agent that Printrak is unable
to protect the interests of such customer related to the GGM product absent the
release of the GGM product Source Code; and (ii) the escrow agent is obligated
to release the Source Code only after providing SCC and Signal Soft with not
less than 30 days written notice of the agent's intent to release same; and
(iii) the costs related to said escrow agreement or the release of the Source
Code shall in no way be borne by SCC or Signal Soft. Any non-conforming escrow
agreement shall be void and shall result in the automatic revocation of any
sublicense granted to Printrak's CAD or RMS customers.

1.2  GGM APPLICATION LICENSES

The grant of license rights to Printrak from SCC provided in Exhibit D of the
Agreement is further clarified herein to include all code necessary to build
complete GGM, TMD and CAD workstation applications, inclusive but not limited to
the following SCC GGM Software Applications in the version level available as of
June 30, 1997:

     *    GGM System License
     *    GGM PC License
     *    GGM System Admin Kit
     *    GCi License
     *    Federation Transfer License
     *    GMi License
     *    Pin Mapping License

2.   DOCUMENTATION

The initial release of each GGM product Source Code to Printrak for Printrak's
business usage shall include one electronic and one hard copy media of the
documentation materials for said GGM product. Thereafter, Printrak shall be
responsible for updating the documentation to reflect any Printrak
modifications, enhancements or improvements to functionality resulting from
Printrak's changes to the Source Code.

SCC and Signal Soft shall be responsible for updating the documentation to
reflect any SCC or Signal Soft modifications, enhancements or improvements to
functionality resulting from either parties' changes to the Source Code.

All such updated documentation shall be shared between Printrak, SCC and Signal
Soft in electronic and hard copy media format for the purposes of conducting
each parties' independent business operations.

3.   SUPPORT AND IMPLEMENTATION SERVICES

Printrak is granted the right to conduct Support and Implementation Services of
the GGM products on an independent basis.

   CONDITIONS PRECEDENT TO EACH ADVANCE. Lender's obligation to make any Advance
   to or for the account of Borrower under this Agreement is subject to the
   following conditions precedent, with all documents, instruments, opinions,
   reports, and other items required under this Agreement to be in form and
   substance satisfactory to Lender:

      (a) Lender shall have received evidence that this Agreement and all
      Related Documents have been duly authorized, executed, and delivered by
      Borrower to Lender.

      (b) Lender shall have received such opinions of counsel, supplemental
      opinions, and documents as Lender may request.

      (c) The security interests in the Collateral shall have been duly
      authorized, created, and perfected with first lien priority and shall be
      in full force and effect.

      (d) All guaranties required by Lender for the Line of Credit shall have
      been executed by each Guarantor, delivered to Lender, and be in full force
      and effect.

      (e) Lender, at its option and for its sole benefit, shall have conducted
      an audit of Borrower's Accounts, books, records, and operations, and
      Lender shall be satisfied as to their condition.

      (f) Borrower shall have paid to Lender all fees, costs, and expenses
      specified in this Agreement and the Related Documents as are then due and
      payable.

      (g) There shall not exist at the time of any Advance a condition which
      would constitute an Event of Default under this Agreement, and Borrower
      shall have delivered to Lender the compliance certificate called for in
      the paragraph below titled "Compliance Certificate."

   MAKING LOAN ADVANCES. Advances under the credit facility, as well as
   directions for payment from Borrower's accounts, may be requested orally or
   in writing by authorized persons. Lender may, but need not, require that all
   oral requests be confirmed in writing. Each Advance shall be conclusively
   deemed to have been made at the request of and for the benefit of Borrower
   (a) when credited to any deposit account of Borrower maintained with Lender
   or (b) when advanced in accordance with the instructions of an authorized
   person. Lender, at its option, may set a cutoff time, after which all
   requests for Advances will be treated as having been requested on the next
   succeeding Business Day.

   MANDATORY LOAN REPAYMENTS. If at any time the aggregate principal amount of
   the outstanding Advances shall exceed the applicable Borrowing Base,
   Borrower, immediately upon written or oral notice from Lender, shall pay to
   Lender an amount equal to the difference between the outstanding principal
   balance of the Advances and the Borrowing Base. On the Expiration Date,
   Borrower shall pay to Lender in full the aggregate unpaid principal amount of
   all Advances then outstanding and all accrued unpaid interest, together with
   all other applicable fees, costs and charges, if any, not yet paid.

   LOAN ACCOUNT. Lender shall maintain on its books a record of account in which
   Lender shall make entries for each Advance and such other debits and credits
   as shall be appropriate in connection with the credit facility. Lender shall
   provide Borrower with periodic statements of Borrower's account, which
   statements shall be considered to be correct and conclusively binding on
   Borrower unless Borrower notifies Lender to the contrary within thirty (30)
   days after Borrower's receipt of any such statement which Borrower deems to
   be incorrect.

COLLATERAL. To secure payment of the Line of Credit and performance of all other
Loans, obligations and duties owed by Borrower to Lender, Borrower (and others,
if required) shall grant to Lender Security Interests in such property and
assets as Lender may require (the "Collateral"), including without limitation
Borrower's present and future Accounts and general intangibles. Lender's
Security Interests in the Collateral shall be continuing liens and shall include
the proceeds and products of the Collateral, including without limitation the
proceeds of any insurance. With respect to the Collateral, Borrower agrees and
represents and warrants to Lender:

   PERFECTION OF SECURITY INTERESTS. Borrower agrees to execute such financing
   statements and to take whatever other actions are requested by Lender to
   perfect and continue Lender's Security Interests in the Collateral. Upon
   request of Lender, Borrower will deliver to Lender any and all of the
   documents evidencing or constituting the Collateral, and Borrower will note
   Lender's Interest upon any and all chattel paper if not delivered to Lender
   for possession by Lender. Contemporaneous with the execution of this
   Agreement, Borrower will execute one or more UCC financing statements and any
   similar statements as may be required by applicable law, and will file such
   financing statements and all such similar statements in the appropriate
   location or locations. Borrower hereby appoints Lender as its irrevocable
   attorney-in-fact for the purpose of executing any documents necessary to
   perfect or to continue any Security Interest. Lender may at any time, and
   without further authorization from Borrower, file a carbon, photograph,
   facsimile, or other reproduction of any financing statement for use as a
   financing statement. Borrower will reimburse Lender for all expenses for the
   perfection, termination, and the continuation of the perfection of Lender's
   security interest in the Collateral. Borrower promptly will notify Lender of
   any change in Borrower's name including any change to the assumed business
   names of Borrower. Borrower also promptly will notify Lender of any change in
   Borrower's Social Security Number or Employer Identification Number. Borrower
   further agrees to notify Lender in writing prior to any change in address or
   location of Borrower's principal governance office or should Borrower merge
   or consolidate with any other entity.

   COLLATERAL RECORDS. Borrower does now, and at all times hereafter shall, keep
   correct and accurate records of the Collateral, all of which records shall be
   available to Lender or Lender's representative upon demand for inspection and
   copying at any reasonable time. With respect to the Accounts, Borrower agrees
   to keep and maintain such records as Lender may require, including without
   limitation information concerning Eligible Accounts and Account balances and
   agings.

   COLLATERAL SCHEDULES. Concurrently with the execution and delivery of this
   Agreement, Borrower shall execute and deliver to Lender a schedule of

   Accounts and such other matters and information relating to Borrower's
   Accounts as Lender may request.

   REPRESENTATIONS AND WARRANTIES CONCERNING ACCOUNTS. With respect to the

   to inspect, examine, and audit Borrower's records and to confirm with Account
   Debtors the accuracy of such Accounts.

proceeds, as of the date of any renewal, extension or modification of any Loan,
and at all times any Indebtedness exists:

   existing, and in good standing under the laws of the state of Borrower's
   incorporation and is validly existing and in good standing in all states in

   to own its properties and to transact the businesses in which it is presently
   engaged or presently proposes to engage. Borrower also is duly qualified as a
   foreign corporation and is in good standing in all states in which the
   failure to so qualify would have a material adverse effect on its businesses
   or financial condition.

   AUTHORIZATION. The execution, delivery, and performance of this Agreement
   and all Related Documents by Borrower, to the extent to be executed,
   delivered or performed by Borrower, have been duly authorized by all
   necessary action by Borrower; do not require the consent or approval of any
   other person, regulatory authority or governmental body; and do not conflict
   with, result in a violation of, or constitute a default under (a) any
   provision of its articles of incorporation or organization, or bylaws, or any
   agreement or other instrument binding upon Borrower or (b) any law,
   governmental regulation, court decree, or order applicable to Borrower.

   FINANCIAL INFORMATION. Each financial statement of Borrower supplied to
   Lender truly and completely disclosed Borrower's financial condition as of
   the date of the statement, and there has been no material adverse change in

Loan No                          (Continued)
================================================================================

   LEGAL EFFECT. This Agreement constitutes, and any instrument or agreement
   required hereunder to be given by Borrower when delivered will constitute,
   legal, valid and binding obligations of Borrower enforceable against Borrower
   in accordance with their respective terms.

   PROPERTIES. Except for Permitted Liens, Borrower owns and has good title to
   all of Borrower's properties free and clear of all Security Interests, and
   has not executed any security documents or financing statements relating to
   such properties. All of Borrower's properties are titled in Borrower's legal
   name, and Borrower has not used, or filed a financing statement under, any
   other name for at least the last five (5) years.

   HAZARDOUS SUBSTANCES. The terms "hazardous waste," "hazardous substance,"
   "disposal," "release," and "threatened release," as used in this Agreement,
   shall have the same meanings as set forth in the "CERCLA," "SARA," the
   Hazardous Materials Transportation Act, 49 U.S.C. Section 1801, et seq., the
   Resource Conservation and Recovery Act, 42 U.S.C. Section 6901, et seq., or
   other applicable state or Federal laws, rules, or regulations adopted
   pursuant to any of the foregoing. Except as disclosed to and acknowledged by
   Lender in writing, Borrower represents and warrants that: (a) During the
   period of Borrower's ownership of the properties, there has been no use,
   generation, manufacture, storage, treatment, disposal, release or threatened
   release of any hazardous waste or substance by any person on, under, about
   or from any of the properties. (b) Borrower has no knowledge of, or reason to
   believe that there has been (i) any use, generation, manufacture, storage,
   treatment, disposal, release, or threatened release of any hazardous waste or
   substance on, under, about or from the properties by any prior owners or
   occupants of any of the properties, or (ii) any actual or threatened
   litigation or claims of any kind by any person relating to such matters. (c)
   Neither Borrower nor any tenant, contractor, agent or other authorized user
   of any of the properties shall use, generate, manufacture, store, treat,
   dispose of, or release any hazardous waste or substance on, under, about or
   from any of the properties; and any such activity shall be conducted in
   compliance with all applicable federal, state, and local laws, regulations,
   and ordinances, including without limitation those laws, regulations and
   ordinances described above. Borrower authorizes Lender and its agents to
   enter upon the properties to make such inspections and tests as Lender may
   deem appropriate to determine compliance of the properties with this section
   of the Agreement. Any inspections or tests made by Lender shall be at
   Borrower's expense and for Lender's purposes only and shall not be construed
   to create any responsibility or liability on the part of Lender to Borrower
   or to any other person. The representations and warranties contained herein
   are based on Borrower's due diligence in investigating the properties for
   hazardous waste and hazardous substances. Borrower hereby (a) releases and
   waives any future claims against Lender for indemnity or contribution in the
   event Borrower becomes liable for cleanup or other costs under any such laws,
   and (b) agrees to indemnify and hold harmless Lender against any and all
   claims, losses, liabilities, damages, penalties, and expenses which Lender
   may directly or indirectly sustain or suffer resulting from a breach of this
   section of the Agreement or as a consequence of any use, generation,
   manufacture, storage, disposal, release or threatened release occurring prior
   to Borrower's ownership or interest in the properties, whether or not the
   same was or should have been known to Borrower. The provisions of this
   section of the Agreement, including the obligation to indemnify, shall
   survive the payment of the indebtedness and the termination or expiration of
   this Agreement and shall not be affected by Lender's acquisition of any
   interest in any of the properties, whether by foreclosure or otherwise.

   LITIGATION AND CLAIMS. No litigation, claim, investigation, administrative
   proceeding or similar action (including those for unpaid taxes) against
   Borrower is pending or threatened, and no other event has occurred which may
   materially adversely affect Borrower's financial condition or properties,
   other than litigation, claims, or other events, if any, that have been
   disclosed to and acknowledged by Lender in writing.

   TAXES. To the best of Borrower's knowledge, all tax returns and reports of

   or transfer, whether now or later, of one or more participation Interests in
   the Loans to one or more purchasers, whether related or unrelated to Lender.
   Lender may provide, without any limitation whatsoever, to any one or more
   purchasers, or potential purchasers, any information or knowledge Lender may
   have about Borrower or about any other matter relating to the Loan, and

   expenses, including without limitation attorneys' fees, incurred in
   connection with the preparation, execution, enforcement, modification and

   attorneys' fees for bankruptcy proceedings (including efforts to modify or

   offending provision shall be deemed to be modified to be within the limits of

   modified, it shall be stricken and all other provisions of this Agreement in

   provisions of this Agreement makes it appropriate, including without
   limitation any representation, warranty or covenant, the word "Borrower" as
   used herein shall include all subsidiaries and affiliates of Borrower.
   Notwithstanding the foregoing however, under no circumstances shall this
   Agreement be construed to require Lender to make any Loan or other financial
   accommodation to any subsidiary or affiliate of Borrower.

   SUCCESSORS AND ASSIGNS. All covenants and agreements contained by or on
   behalf of Borrower shall bind its successors and assigns and shall inure to
   the benefit of Lender, its successors and assigns. Borrower shall not,
   however, have the right to assign its rights under this Agreement or any
   interest therein, without the prior written consent of Lender.

   SURVIVAL. All warranties, representations, and covenants made by Borrower
   in this Agreement or in any certificate or other instrument delivered by
   Borrower to Lender under this Agreement shall be considered to have been
   relied upon by Lander and will survive the making of the Loan and delivery to
   Lander of the Related Documents, regardless of any investigation made by
   Lander or on Lender's behalf.

   TIME IS OF THE ESSENCE. Time is of the essence in the performance of this
   Agreement.

   WAIVER. Lender shall not be deemed to have waived any rights under this
   Agreement unless such waiver is given in writing and signed by Lender. No
   delay or omission on the part of Lender in exercising any right shall operate
   as a waiver of such right or any other right. A waiver by Lender of a
   provision of this Agreement shall not prejudice or constitute a waiver of
   Lender's right otherwise to demand strict compliance with that provision or
   any other provision of this Agreement. No prior waiver by Lender, nor any
   course of dealing between Lender and Borrower, or between Lender and any
   Grantor, shall constitute a waiver of any of Lender's rights or of any
   obligations of Borrower or of any Grantor as to any future transactions.
   Whenever the consent of Lender is required under this Agreement, the granting
   of such consent by Lender in any instance shall not constitute continuing
   consent in subsequent instances where such consent is required, and in all
   cases such consent may be granted or withheld in the sole discretion of
   Lender.

PRINCIPAL AMOUNT: $2,000,000.00               DATE OF AGREEMENT: APRIL 15, 1997

   DESCRIPTION OF EXISTING INDEBTEDNESS. A PROMISSORY NOTE DATED JULY 1, 1996,
   IN THE ORIGINAL PRINCIPAL AMOUNT OF $2,000,000.00.

   DESCRIPTION OF CHANGE IN TERMS. THE MATURITY DATE WILL NOW BE APRIL 15, 1998.

   PROMISE TO PAY. SCC COMMUNICATIONS CORP., A DELAWARE CORPORATION ("Borrower")
   promises to pay to BANK ONE, COLORADO, N.A. ("Lender"), or order, in lawful
   money of the United States of America, the principal amount of Two Million
   &00/100 Dollars ($2,000,000.00) or so much as may be outstanding, together
   with interest on the unpaid outstanding principal balance of each advance.
   Interest shall be calculated from the date of each advance until repayment of
   each advance.

   PAYMENT. Borrower will pay this loan in one payment of all outstanding
   principal plus all accrued unpaid interest on April 15, 1998. In addition,
   Borrower will pay regular monthly payments of accrued unpaid interest
   beginning May 15, 1997, and all subsequent interest payments are due on the
   same day of each month after that. Interest on this Agreement is computed on
   a 365/360 simple interest basis; that is, by applying the ratio of the annual
   interest rate over a year of 360 days, multiplied by the outstanding
   principal balance, multiplied by the actual number of days the principal
   balance is outstanding. Borrower will pay Lender at Lender's address shown
   above or at such other place as Lender may designate in writing. Unless
   otherwise agreed or required by applicable law, payments will be applied
   first to accrued unpaid interest, then to principal, and any remaining amount
   to any unpaid collection costs and late charges.

   VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to
   change from time to time based on changes in an index which is the LENDER'S
   PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
   ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY
   GIVEN TIME, THE LENDER MAY MAKE LOANS, AT, ABOVE, OR BELOW ITS PRIME RATE.
   Lender will tell Borrower the current Index rate upon Borrower's request.
   Borrower understands that Lender may make loans based on other rates as well.
   The interest rate change will not occur more often than each DAY. The Index
   currently is 8.500% per annum. The interest rate to be applied to the unpaid
   principal balance of this Agreement will be at a rate of 1.000 percentage
   point over the Index, resulting in an initial rate of 9.500% per annum.
   NOTICE: Under no circumstances will the interest rate on this Agreement be
   more than the maximum rate allowed by applicable law.

   PREPAYMENT; MINIMUM INTEREST CHARGE. Borrower agrees that all loan fees and
   other prepaid finance charges are earned fully as of the date of the loan and
   will not be subject to refund upon early payment (whether voluntary or as a
   result of default), except as otherwise required by law. In any event, even
   upon full prepayment of this Agreement, Borrower understands that Lender is
   entitled to a minimum interest charge of $25.00. Other than Borrower's
   obligation to pay any minimum interest charge, Borrower may pay without
   penalty all or a portion of the amount owed earlier than it is due. Early
   payments will not, unless agreed to by Lender in writing, relieve Borrower of
   Borrower's obligation to continue to make payments of accrued unpaid
   interest. Rather, they will reduce the principal balance due.

   DEFAULT. Borrower will be in default if any of the following happens: (a)
   Borrower fails to make any payment when due. (b) Borrower breaks any promise
   Borrower has made to Lender, or Borrower fails to comply with or to perform
   when due any other term, obligation, covenant, or condition contained in this
   Agreement or any agreement related to this Agreement, or in any other
   agreement or loan Borrower has with Lender. (c) Borrower defaults under any
   loan, extension of credit, security agreement, purchase or sales agreement,
   or any other agreement, in favor of any other creditor or person that may
   materially affect any of Borrower's property or Borrower's ability to repay
   this Note or perform Borrower's obligations under this Note or any of the
   Related Documents. (d) Any representation or statement made or furnished to
   Lender by Borrower or on Borrower's behalf is false or misleading in any
   material respect either now or at the time made or furnished. (a) Borrower
   becomes insolvent, a receiver is appointed for any part of Borrower's
   property, Borrower makes an assignment for the benefit of creditors, or any
   proceeding is commenced either by Borrower or against Borrower under any
   bankruptcy or Insolvency laws. (f) Any creditor tries to take any of
   Borrower's property on or in which Lender has a lien or security interest.
   This includes a garnishment of any of Borrower's accounts with Lender. (g)
   Any guarantor dies or any of the other events described in this default
   section occurs with respect to any guarantor of this Agreement. (h) A
   material adverse change occurs in Borrower's financial condition, or Lender
   believes the prospect of payment or performance of the indebtedness is
   impaired.

   LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
   balance on this Agreement and all accrued unpaid interest immediately due,
   without notice, and then Borrower will pay that amount. Upon default,
   including failure to pay upon final maturity, Lender, at its option, may
   also, if permitted under applicable law, do one or both of the following: (a)
   increase the variable interest rate on this Agreement to 25.000% per annum,
   and (b) add any unpaid accrued interest to principal and such sum will bear
   interest therefrom until paid at the rate provided in this Agreement
   (including any increased rate). The interest rate will not exceed the
   maximum rate permitted by applicable law. Lender may hire or pay someone else
   to help collect this Agreement if Borrower does not pay. Borrower also will
   pay Lender that amount. This includes, subject to any limits under applicable
   law, Lender's attorneys' fees and Lender's legal expenses whether or not
   there is a lawsuit, including attorneys' fees and legal expenses for
   bankruptcy proceedings (including efforts to modify or vacate any automatic
   stay or injunction), appeals, and any anticipated post-judgment collection
   services. If not prohibited by applicable law, Borrower also will pay any
   court costs, in addition to all other sums provided by law. THIS AGREEMENT
   HAS BEEN DELIVERED TO LENDER AND ACCEPTED BY LENDER IN THE STATE OF COLORADO.
   IF THERE IS A LAWSUIT, BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE
   JURISDICTION OF THE COURTS OF BOULDER COUNTY, THE STATE OF COLORADO. LENDER
   AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION,
   PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE
   OTHER. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
   THE LAWS OF THE STATE OF COLORADO.

   RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
   interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
   Lender all Borrower's right, title and interest in and to, Borrower's
   accounts with Lender (whether checking, savings, or some other account),
   including without limitation all accounts held jointly with someone else and
   all accounts Borrower may open in the future, excluding however all IRA and
   Keogh accounts, and all trust accounts for which the grant of a security
   interest would be prohibited by law. Borrower authorizes Lender, to the
   extent permitted by applicable law, to charge or setoff all sums owing on
   this Agreement against any and all such accounts.

   LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
   under this Agreement, as well as directions for payment from Borrower's
   accounts, may be requested orally or in writing by Borrower or by an
   authorized person. Lender may, but need not, require that all oral requests
   be confirmed in writing. Borrower agrees to be liable for all sums either:
   (a) advanced in accordance with the instructions of an authorized person or
   (b) credited to any of Borrower's accounts with Lender. The unpaid principal
   balance owing on this Agreement at any time may be evidenced by endorsements
   on this Agreement or by Lender's internal records, including daily computer
   print-outs. Lender will have no obligation to advance funds under this
   Agreement if: (a) Borrower or any guarantor is in default under the terms of
   this Agreement or any agreement that Borrower or any guarantor has with
   Lender, including any agreement made in connection with the signing of this
   Agreement; (b) Borrower or any guarantor ceases doing business or is
   insolvent; (c) any guarantor seeks, claims or otherwise attempts to limit,
   modify or revoke such guarantor's guarantee of this Agreement or any other
   loan with Lender; or (d) Borrower has applied funds provided pursuant to this
   Agreement for purposes other than those authorized by Lender.

   CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms
   of the original obligation or obligations, including all agreements evidenced
   or securing the obligations(s), remain unchanged and in full force and
   effect. Consent by Lender to this Agreement does not waive Lender's right to
   strict performance of the obligation(s) as changed, nor obligate Lender to
   make any future change in terms. Nothing in this Agreement will constitute a
   satisfaction of the obligation(s). It is the intention of Lender to retain as
   liable parties all makers and endorsers of the original obligation(s),
   including accommodation parties, unless a party is expressly released by
   Lender in writing. Any maker or endorser, including accommodation makers,
   will not be released by virtue of this Agreement, if any person who signed
   the original obligation does not sign this Agreement below, then all persons
   signing below acknowledge that this Agreement is given conditionally, based
   on the representation to Lender that the non-signing party consents to the
   changes and provisions of this Agreement or otherwise will not be released by
   it. This waiver applies not only to any initial extension, modification or
   release, but also to all such subsequent actions.

   Lender's security interest in the collateral; and take any other action

fact necessary in order to make the statements contained herein or therein, in
light of the circumstances under which they were made, not misleading.

       SECTION 6   REPRESENTATIONS AND WARRANTIES OF THE PURCHASER.

       The representations and warranties of the Purchaser set forth in this
Section 6 shall survive the purchase and sale of the Note and Warrant, and any
investigation made by the Seller shall not diminish the right of the Seller to
rely upon such representations and warranties.  The Purchaser represents and
warrants to the Seller as follows.

         6.1     ORGANIZATION.  The Purchaser represents and warrants that it
is a limited liability company duly organized and validly existing under the
laws of the state of its formation and the





                                      14
<PAGE>   17
execution, delivery and performance by the Purchaser of this Agreement, each of
the Related Documents to which it is a party and of any instrument or agreement
required by this Agreement and the Related Documents to which it is a party are
within its powers, have been duly authorized, and are not in conflict with the
terms of any provision of its partnership agreement or other organizational
documents.

         6.2     NO CONFLICTS.  The execution, delivery and performance of this
Agreement, the Related Documents and any other instrument or agreement required
by this Agreement to which the Purchaser is a party have been duly authorized
by all requisite action on the part of the Purchaser and are not in conflict
with any law or any material indenture, agreement or undertaking to which the
Purchaser is a party or by which the Purchaser is bound or affected.

         6.3     ENFORCEABILITY.  This Agreement is a legal, valid and binding
agreement of the Purchaser, enforceable against the Purchaser in accordance
with its terms and the Related Documents and any other instrument or agreement
required under this Agreement, when executed or delivered by the Purchaser,
will be legal, valid, binding and enforceable in accordance with their
respective terms, subject to (a) laws of general application relating to
bankruptcy, insolvency, and the relief of debtors, (b) rules of law governing
specific performance, injunctive relief, or other equitable remedies, and (c)
the extent that the indemnification provisions in Section 12 may be limited by
principles of public policy.

         6.4     AUTHORIZATION AND CONSENTS.  No approval, consent, compliance,
exemption, authorization or other action by, or notice to, or filing with, any
governmental authority or any other Person pursuant to Applicable Law, and no
lapse of the waiting period under the Applicable Law, is necessary or required
in connection with the execution, delivery and performance by the Purchaser or
enforcement against the Purchaser of this Agreement and the Related Documents
to which the Purchaser is a party or the transactions contemplated hereby or
thereby.

         6.5     EXPERIENCE.  The Purchaser is an accredited investor within
the meaning of Rule 501(a) of Regulation D promulgated under the Securities Act
and has substantial experience in evaluating and investing in securities of
companies similar to the Seller and has made investments of securities other
than those of the Seller.  The Purchaser acknowledges that by reason of its
business or financial experience and financial condition, it has the ability to
analyze and bear the entire risk of its investment pursuant to this Agreement,
the Note and the Warrant.

         6.6     INVESTMENT INTENT.  The Purchaser is acquiring the Note and
the Warrant for investment for its own account, not as a nominee or agent and
not with a view to, or for resale in connection with, any distribution thereof.
The Purchaser may sell a beneficial interest (but not of record) in the Note
and a proportionate share of the Warrant Shares to Accredited Investors.  The
Purchaser understands that the issuance and sale of the Securities purchased by
it hereunder (and





                                      15
<PAGE>   18
the issuance of Warrant Shares upon the exercise of the Warrant) have not been,
and will not be, subject to a registration statement filed under the Securities
Act or any applicable state securities law by reason of a specific exemption
from the registration provisions of the Securities Act and such state
securities laws, which exemption depends upon, among other things, the bona
fide nature of the investment intent and the accuracy of the Purchaser's
representation as expressed herein.

         6.7     RULE 144.  The Purchaser acknowledges that the securities
which are or could be acquired hereunder are restricted securities within the
meaning of Rule 144 promulgated under the Securities Act and must be held
indefinitely unless subsequently registered under the Securities Act and
applicable state securities laws or unless an exemption from such registration
is available.  The Purchaser is aware of the provisions of Rule 144 promulgated
under the Securities Act which permits the limited resale of securities
purchased in a private placement subject to the satisfaction of certain
conditions.

         6.8     KNOWLEDGE OF PURCHASER.  The Purchaser is aware of and has
investigated the Seller's business, management and financial condition, has had
the opportunity to inspect the Seller's facilities and meet with the Seller's
management and has had access to such other information about the Seller as the
Purchaser has deemed necessary and desirable to reach an informed and
knowledgeable decision to acquire the Securities to be purchased by it
hereunder.  The purchase of such Securities is not a result of an advertisement
of an offering in connection with the sale of such Securities.

       7.5       CHANGES IN GAAP AND IN PRACTICES, POLICIES AND PROCEDURES.

procedures applied in connection with the preparation of its Annual or
Quarterly Financial Statements, the Seller shall:

                 (i)      notify the Purchaser in writing of such proposed
                          change at least forty-five (45) days prior to the
                          required delivery date of the first Annual or
                          Quarterly Financial Statement that will be effected
                          by such proposed change;

                 (ii)     state in reasonable detail in such notice the reason
                          for such change, including, if applicable, a
                          description of any change in GAAP that occasions such
                          change;

                 (iii)    submit with such notice a written statement by the
                          chief financial officer of the Seller describing the
                          anticipated effect, if any, of the proposed change to
                          the computation of the Financial Tests, or stating
                          that in his opinion such proposed change will have no
                          material effect on the computation of such Financial
                          Tests; and

                 (iv)     in the event such proposed change will have a
                          material effect on the computation of such Financial
                          Tests, submit with each Compliance Certificate a
                          written reconciliation in reasonable detail
                          demonstrating the computation of the Financial Tests

such proposed change without the written consent of the Purchaser, which
consent shall not be unreasonably withheld by the Purchaser.

         (c)     Effect of Change on Financial Tests.  In the event that any
such change in policies, practice or procedures would materially affect the

appropriate modifications to such Financial Test, compliance with all such
Financial Test shall be determined on a proforma basis without giving effect to
any such change.

Report has been delivered; provided, however, that the maximum assessment with
respect to the delivery of any one Financial Report shall be $2,500.  The
Seller shall pay any such assessment upon demand.  The assessment of any such
late delivery fee shall not constitute a waiver of the associated Default.

       12.2      PROCEDURES FOR INDEMNIFIED LOSSES.  In order to claim
Indemnified Losses under this Section:

         (a)     Purchaser shall give written Notice to the Seller of any
claimed Indemnified Losses, which Notice shall set forth a reasonably detailed
statement of the Indemnified Losses, including the cost, expense, loss, damage
and liability Purchaser has incurred and expects to incur by reason thereof.

         (b)     Such Indemnified Loss shall be effected on the last to occur
of (i) the expiration of 30 days from the date of such Notice (the "Notice of
Contest Period"); (ii) if such claim is contested as hereinafter provided, the
date the dispute is resolved in accordance with this Section, or (iii) the date
such claim becomes liquidated in amount.

         (c)     If, prior to the expiration of the Notice of Contest Period,
the Seller notifies Purchaser in writing of the Seller's intention to dispute
the claim for Indemnified Losses, and if such dispute is not resolved with 30
days after the expiration of such Notice of Contest Period ("Resolution
Period"), then the matter may be submitted by Purchaser and the Seller to a
Person recognized in the field of alternate dispute resolution agreed upon by
the Parties ("Mediator") within 10 days after the expiration of the Resolution
Period.  The Mediator shall be requested to recommend to the Parties in writing
a procedure for non-binding mediation ("Mediation") to resolve such dispute.
The Parties shall cooperate and diligently pursue resolution through Mediation
within 45 days after the Mediator has been agreed upon.  If the dispute cannot
be resolved within such period as the Mediator deems reasonable, the Mediator
shall, upon the request of Purchaser or the Seller, certify to the Parties that
the dispute is incapable of resolution through the Mediation process.  The
expenses of such Mediation (excluding expenses incurred solely by Purchaser or
the Seller in such Mediation, which shall be borne by the party incurring such
expenses) shall be borne 50% by Purchaser and 50% by the Seller.  Since the
Mediation is conducted for the purpose of settling the dispute, all proposals
and settlement offers shall be inadmissible for any purpose (including
arbitration) by virtue of Rule 408 of the Federal Rules of Evidence and the
principles expressed in such rule.

         (d)     If Purchaser and the Seller are unable to agree upon a
Mediator within 10 days after the Resolution Period or the Mediator certifies
to the Parties that the dispute is incapable of resolution through the
Mediation process, then such dispute shall be resolved by a committee of three
arbitrators (one appointed by the Seller, one appointed by Purchaser and one
appointed by the other two so appointed), who shall be appointed within 60 days
after such inability to agree or such certification by the Mediator.  The
arbitrators shall be located in, and the arbitration shall take place, in
Columbus, Ohio in accordance with the rules of the American Arbitration
Association and their decision shall be final and binding on the Seller and
Purchaser.  The expenses of such arbitration (excluding expenses incurred
solely by Purchaser or the Seller in bringing or defending such proceeding,
which shall be borne by the party incurring such expenses) shall be borne
one-half by Purchaser and one-half by the Seller.  The Parties shall





                                      25
<PAGE>   28
cooperate and diligently pursue the arbitration of such claim for offset in
order for a decision to be made by the arbitrators within 45 days after their
appointment.

is embodied in this Agreement or the Related Documents expressly or by

<PAGE>   8
       (a)    Remedies.  After payment of this Note is Accelerated, the Payee
shall have (i) all rights and remedies granted to it under this Note and the
Purchase Agreement, and (ii) all rights of a creditor under Applicable Law
(including the UCC).  All such rights and remedies and the exercise thereof
shall be cumulative.  No exercise of any such rights and remedies shall be
deemed to be exclusive or constitute an election of remedies.

       (b)    Acceleration of Payment.   Upon the occurrence of a Voluntary
Insolvency Default or Involuntary Insolvency Default, payment of this Note
shall be Accelerated automatically and without Notice.  Upon the occurrence and
during the continuation of any other Event of Default, the Payee may, in the
sole exercise of its discretion, elect to cause payment of this Note to be
Accelerated by giving Notice of such election to the Maker ("Acceleration
Notice").  Once payment of this Note has been properly Accelerated as provided
for in this section, such  Acceleration may be revoked only by the Payee, in
the sole exercise of its discretion, by giving Notice of revocation to the
Maker, regardless whether the Event of Default giving rise to such Acceleration
has been remedied by action of the Maker.

       (c)    Waiver of Default.  No Default or Event of Default may be waived
nor shall be deemed to have been waived except by an express Notice by the
Payee to the Maker, and any such grant of waiver shall be applicable only to
the specific Defaults or Events of Default expressly identified in such Notice
and shall not be deemed to apply to any other or subsequent Default or Event of
Default.  The Payee may grant or withhold any such waiver in the sole exercise
of its discretion, which may be conditioned upon the payment by the Maker of a
premium, the grant of collateral to secure the payment of this Note or the
acceptance of other terms and conditions under this Note or the Purchase
Agreement.  No course of dealing by the Payee or its agents and employees, or
the failure, forebearance or delay by the Payee in exercising any of its rights
or remedies under this Note or the Purchase Agreement or any other Related
Document shall operate as a waiver of any Default or Event of Default or of any
right of the Payee under this Note.


<PAGE>   9
       SECTION 10.   WAIVERS BY MAKER.

       To the full extent permitted by Applicable Law, Maker waives with
respect to this Note: presentment; protest and demand;  notice of protest,
demand and dishonor; and diligence in collection.  Maker agrees that the Payee
may release all or any part of any collateral securing the payment of this
Note; any guarantor or surety with respect to this Note; or any other Maker
from its obligation with respect to this Note, all without notice to Maker and
without affecting in any way the obligation of Maker under this Note.

       SECTION 11.   INTENTIONALLY BLANK.

       SECTION 12.   INTERCREDITOR AGREEMENT.

       The Payee and the Senior Lender are parties to an Intercreditor
Agreement dated as of the date hereof, pursuant to which certain of the Payee's
rights under this Note are subordinated to the Senior Lender.  Nothing in this
Note, the Purchase Agreement or such Intercreditor Agreement shall grant to
Maker any rights as a beneficiary under such Intercreditor Agreement nor any
right to enforce against the Payee any provision of such Intercreditor
Agreement.

       SECTION 13.   COLLECTION AND ASSESSMENT FOR COSTS.

       The Maker shall reimburse the Payee for all reasonable costs and
expenses (including legal fees and disbursements) incurred by the Payee in
connection with the collection or attempted collection of the payment of this
Note through legal proceedings or otherwise except to the extent that such
costs and expenses are incurred in an action in which it is ultimately
determined that the Maker was not in breach of its obligations to the Payee.
All such amounts shall be deemed to be "Assessments" for purposes of this Note.

       SECTION 14.   AMENDMENT.

       This Note may not be amended, restated, supplemented or otherwise
modified except by an express written agreement executed and delivered by the
Maker and the Payee.  Compliance with the covenants and other provisions of
this Note may not be waived except by an express written waiver signed and

<PAGE>   10
       SECTION 15.   GOVERNING LAW.

       SECTION 16.   WAIVER OF JURY TRIAL.

       THE PAYEE AND THE MAKER, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY

                                                   Dated as of November 20, 1997

         This certifies that, for value received, BANC ONE CAPITAL PARTNERS II,
LLC (the "Holder"), is entitled to purchase from SCC COMMUNICATIONS CORP., a
Delaware corporation (the "Company"), in a single exercise that number of
shares of the Common Stock of the Company equal to four percent (4%) of the
Fully Diluted Common Stock of the Company on the date hereof, subject to
adjustment as provided herein, in the manner and subject to the terms and
conditions set forth herein.

         This Warrant is being issued by the Company pursuant to the Senior
Subordinated Note and Warrant Purchase Agreement dated as of November 20, 1997,
by and between the Company, as seller, and the Holder, as purchaser (the
"Purchase Agreement").

         THIS WARRANT CERTIFICATE IS ONE OF THE "RELATED DOCUMENTS" REFERRED TO
IN THE PURCHASE AGREEMENT.

         SECTION 1.       DEFINITIONS.

         All capitalized terms not otherwise defined herein shall have the
definitions set forth in the Glossary of Defined Terms attached to the Purchase
Agreement, which definitions are, to the extent applicable, incorporated in
this Warrant by reference.

         SECTION 2.       DURATION AND EXERCISE OF WARRANT.

                 2.1      WARRANT EXERCISE PERIOD.  This Warrant shall be
exercisable in a single exercise at any time on or after the date hereof but on
or before the Warrant Exercise  Expiration Date.

                 2.2      MANNER OF EXERCISE.  This Warrant shall be
exercisable for shares of  Voting Stock.  This Warrant may be exercised by the
Holder in a single exercise upon surrender of this Warrant and Notice of
Exercise attached hereto duly completed and executed on behalf of the Holder,
at the principal office of the Company (or at such other office or agency of
the Company as it may designate by Notice in writing to the Holder at the
address of the Holder appearing on the books of the Company), upon payment of
the Exercise Price by wire transfer or delivery of a certified or cashier's
check payable to the Company.  The Holder may, in lieu of paying the Exercise
Price by wire transfer or delivery of a certified or cashier's check to the
Company, reduce the unpaid principal amount of the Note by an amount equal to
the funds which would otherwise have been delivered.
<PAGE>   4
                 2.3      WHEN EXERCISE EFFECTIVE.   Subject to the
requirements of any state or federal laws or regulations to which the Company
may be subject, the exercise of this Warrant shall be deemed to have been
effected immediately prior to the close of business on the Business Day on
which this Warrant shall have been surrendered and the Company receives payment
of the Exercise Price as provided in Section 2.2, and immediately prior to the
close of business on such Business Day the Holder shall be deemed to have
become the holder of record of the Warrant Shares.

                 2.4      DELIVERY OF STOCK CERTIFICATES, ETC.  As soon as
practicable after the exercise of this Warrant, and in any event within five
(5) Business Days thereafter, the Company at its expense (including the payment
by it of any applicable issue taxes) will cause to be issued in the name of and
delivered to the Holder a certificate or certificates for the number of Warrant
Shares to which the Holder shall be entitled upon such exercise, rounded up to
the nearest whole share.

         SECTION 3.       ADJUSTMENTS TO NUMBER OF WARRANT SHARES.

         The number of Warrant Shares that may be purchased by the Holder in
consideration of the payment of the Exercise Price is the Initial Number of
shares of Common Stock; provided, however, that such number of shares is
subject to adjustment as provided for in this Section 3.  The Exercise Price is
not subject to adjustment.

                 3.1      PREFERRED SHARE EQUIVALENT ADJUSTMENT.   For so long
as any Preferred Shares remain outstanding, the number of Warrant Shares that
may be purchased upon exercise of this Warrant shall be as follows.
Thereafter, such number shall be subject to adjustment only as provided in
Section 3.2.

                 (a)      The number of Warrant Shares that may be purchased
upon exercise of this Warrant shall be the Initial Number multiplied by a
fraction, the denominator of which is the Applicable Conversion Price and the
numerator of which is the Applicable Original Conversion Price.

                 (b)      As used in this Agreement, (i) "Applicable Original
Conversion Price" means $1.36 if any Series F Preferred Shares are outstanding,
$0.81 if any Series E Preferred Shares are outstanding, or $0.59 if no Series E
Preferred Shares are outstanding or $0.55 if no Series D or E Preferred Shares
are outstanding or $0.33 if no Series C, D or E Preferred Shares are
outstanding; (ii) "Applicable Conversion Price" means the highest Conversion
Price per share then in effect with respect to outstanding Series A, B, C, D or
E Preferred Shares as adjusted pursuant to paragraph 6 of Article Fourth of the
Company's Amended Certificate of Incorporation; (iii) "Initial Number" means
that number of shares of Common Stock equal to
<PAGE>   5
four percent (4%) of the Fully Diluted Common Stock of the Company on the date
hereof, as adjusted pursuant to Section 3.2, if applicable.  On the date
hereof, the Initial Number is 1,170,892.

                 3.2      ANTIDILUTION ADJUSTMENT.  After no Preferred Shares
remain outstanding, the number of Warrant Shares that may be purchased upon
exercise of this Warrant shall be the number of Warrant Shares that would have
been issuable upon exercise of this Warrant had it been exercised on the last
day that any Preferred Shares remain outstanding; provided, that upon any
subsequent occurrence of an Adjustment Event, such number of Warrant Shares
shall be adjusted immediately after the applicable record date with respect to
such Adjustment Event as follows.  The adjusted number of Warrant Shares shall
be a number equal to the number of Warrant Shares immediately prior to such
record date multiplied by a fraction (i) the numerator of which is the number
of shares of Outstanding Common Stock immediately after such Adjustment Event,
and (ii) the denominator of which is the number of shares of Outstanding Common
Stock immediately prior to such record date.  Any such adjustment shall be
calculated to the nearest 0.001 Warrant Share.

                 3.3      REORGANIZATION EVENT.  Upon the occurrence of a
Reorganization Event, there shall thereafter be issuable upon the exercise of
this Warrant (in lieu of the Warrant Shares), as appropriate, the number of
shares of stock, other securities or property to which the Holder of the number
of shares of Common Stock equal to the number of Warrant Shares at the date of
the Reorganization Event would have been entitled to as a result of such
Reorganization Event.

         Prior to and as a condition of the consummation of any Reorganization
Event, the Company shall cause effective provisions to be made to effect the
purposes of this Section 3.3, including, if appropriate, an agreement among the
Company, any successor to the Company and the Holder.

                 3.4      OTHER ADJUSTMENTS.

                 (a)      QUALIFIED OFFERING WITHIN EIGHTEEN MONTHS.  If the
Seller completes a Qualified Public Offering within eighteen (18) months of the
date hereof, the number of Warrant Shares that may be purchased by the Holder
in consideration of the payment of the Exercise Price shall be reduced to the
Initial Number multiplied by 75%, subject to adjustment as provided for in
Section 3.1 or Section 3.2, if applicable.

                 (b)      QUALIFIED OFFERING WITHIN TWELVE MONTHS.  If the
Seller completes a Qualified Public Offering within twelve (12) months of the
date hereof, the number of Warrant Shares that may be purchased by the Holder
in consideration of the payment of the Exercise Price shall be reduced to the
Initial Number multiplied by 50%, subject to adjustment as provided for in
Section 3.1 or Section 3.2, if applicable.

         SECTION 4.       RESTRICTIONS ON TRANSFER.

                 4.1      RESTRICTIVE LEGENDS.  Except as otherwise permitted
by this Section 4, this Warrant and each Warrant issued in exchange or
substitution for any Warrant, and each Warrant issued upon the registration of
transfer of any Warrant and each certificate representing Warrant Shares and
each certificate issued upon the registration of Transfer of any Warrant
Shares, shall be stamped or otherwise imprinted with a legend in substantially
the following form:

"THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE,
AND MAY NOT BE DISTRIBUTED, SOLD, TRANSFERRED, ASSIGNED, HYPOTHECATED OR
OFFERED UNLESS THERE IS IN EFFECT A REGISTRATION STATEMENT UNDER SUCH ACT AND
LAWS COVERING SUCH SECURITIES OR THE ISSUER RECEIVES AN OPINION OF COUNSEL FOR
THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE ISSUER OR A
NO-ACTION LETTER FROM THE SECURITIES EXCHANGE COMMISSION STATING THAT SUCH
DISTRIBUTION, SALE, TRANSFER, ASSIGNMENT, HYPOTHECATION OR OFFER IS EXEMPT FROM
THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT AND LAWS."

                 4.2      NOTICE OF PROPOSED TRANSFER; OPINIONS OF COUNSEL.
Prior to any Transfer of any Restricted Securities, the Holder will give
written Notice to the Company of the Holder's intention to effect such Transfer
and to comply in all other respects with this Section 4.2.  Each such Notice of
a proposed Transfer (a) shall describe the manner and circumstances of the
proposed Transfer in sufficient detail to enable counsel to render the opinion
referred to below, and (b) shall designate counsel for the Holder.  The Holder
will submit a copy thereof to the counsel designated in such Notice and the
Company will promptly submit a copy thereof to its counsel. The following
provisions shall then apply:

                      (i)         If in the opinion of counsel to the Company
                                  the proposed Transfer may be effected without
                                  registration of such Restricted Securities
                                  under the Securities Act, the Company will
                                  promptly notify the Holder and the Holder
                                  shall thereupon be entitled to Transfer such
                                  Restricted Securities in accordance with the
                                  terms of the Notice delivered by the Holder
                                  to the Company.  Each Warrant or certificate,
                                  if any, issued upon or in connection with
                                  such Transfer shall bear the applicable
                                  restrictive legend set forth in section 4.1,
                                  unless in the opinion of such counsel such
                                  legend is no longer
<PAGE>   7
                                  required to ensure compliance with the
                                  Securities Act.  If for any reason counsel
                                  for the Company (after having been furnished
                                  with the information required to be furnished
                                  by clause (a) of this Section 4.2) shall fail
                                  to deliver an opinion to the Company, or the
                                  Company shall fail to notify the Holder as
                                  aforesaid, within thirty (30) days after
                                  receipt of Notice of the Holder's intention
                                  to effect a Transfer, then for all purposes
                                  of this Warrant the opinion of counsel for
                                  the Holder shall be sufficient to authorize
                                  the proposed Transfer and the opinion of
                                  counsel for the Company shall not be required
                                  in connection with such proposed Transfer;
                                  and

                      (ii)        If in the opinion of counsel to the Company
                                  the proposed Transfer may not be effected
                                  without registration of such Restricted
                                  Securities under the Securities Act, the
                                  Company will promptly so notify the Holder
                                  and the Holder shall not be entitled to
                                  Transfer such Restricted Securities until
                                  receipt of a further notice from the Company
                                  under clause (i) above or until registration
                                  of such Restricted Securities under the
                                  Securities Act has become effective.

                    (iii)         Holder agrees to provide or cause the
                                  proposed transferee to provide any additional
                                  information and cooperation that the Company
                                  may reasonably request in connection with
                                  such proposed Transfer, including
                                  representations and warranties from the
                                  proposed transferee in the event such
                                  securities are not registered under the
                                  Securities Act.

         SECTION 5.       AVAILABILITY OF INFORMATION.

         The Company will comply with the reporting requirements of Sections 13
and 15(d) of the Securities Exchange Act insofar as they are applicable to the
Company and will comply with all other public information reporting
requirements of the Commission (including the requirements of Rule 144
promulgated by the Commission under the Securities Act) from time to time in
effect and relating to the availability of an exemption from the Securities Act
for the sale of any Restricted Securities or the sale of securities by
Affiliates.  The Company will also cooperate with the Holder at the Holder's
expense to complete and file any information reporting forms presently or
hereafter required by the Commission as a condition to the availability of an
exemption from the Securities Act for the sale of any Restricted Securities or
the sale of securities by affiliates.
<PAGE>   8
         SECTION 6.       RESERVATION OF STOCK, ETC.

         The Company will at all times reserve and keep available, solely for
issuance and delivery upon the exercise of this Warrant and free from
preemptive rights, a sufficient number of shares of Common Stock to cover the
Warrant Shares issuable or exchangeable upon the exercise of this Warrant.  All
such shares shall be duly authorized and, when issued upon such exercise, shall
be validly issued, fully paid and non-assessable with no liability on the part
of the holders thereof.

         SECTION 7.       OWNERSHIP; REGISTRATION OF TRANSFER; EXCHANGE AND 
                          SUBSTITUTION OF WARRANT.

                 7.1      OWNERSHIP OF WARRANT.  Until due presentment for
registration, the Company may treat the Person in whose name this Warrant is
registered on the register kept at the Company's principal office as the owner
and holder thereof for all purposes, notwithstanding any Notice to the
contrary, except that, if and when this Warrant is properly assigned to another
Person, the Company may (but shall not be obligated to) treat such Person as
the owner of this Warrant for all purposes, notwithstanding any Notice to the
contrary.  Subject to the foregoing provisions and to Section 4, this Warrant,
if properly assigned, may be exercised by the assignee without first having a
new Warrant issued.

                 7.2      REGISTRATION OF TRANSFERS.  Subject to Section 4
hereof, the Company shall register the Transfer of this Warrant permitted under
the terms hereof upon records to be maintained by the Company for that purpose,
upon surrender of this Warrant, with the Form of Assignment attached hereto
duly completed and signed, to the Company at the Company's principal office.
Upon any such registration of Transfer, a new Warrant, in substantially the
form of this Warrant, shall be issued to the transferee.

                 7.3      REPLACEMENT OF WARRANT CERTIFICATE.  Upon receipt of
evidence reasonably satisfactory to the Company of the loss, theft, destruction
or mutilation of this Warrant and upon delivery of indemnity reasonably
satisfactory to the Company in form and amount, or, in the case of any such
mutilation, upon surrender of this Warrant for cancellation at the Company's
principal office, the Company at its expense will promptly execute and deliver,
in lieu thereof, a new Warrant of like tenor.

                 7.4      EXPENSES.  The Company will pay all expenses, taxes
(other than transfer and income taxes) and other charges payable by the Holder
in connection with the preparation, issuance and delivery from time to time of
this Warrant or the Warrant Shares.  The Holder will pay all costs and expenses
associated with the transfer of this Warrant or the Warrant Shares by the
Holder.
<PAGE>   9
         SECTION 8.       OTHER RIGHTS OF HOLDER.

         The Warrant Shares shall be subject to the terms and conditions of the
Preemptive Rights Agreement, Option Agreement, Registration Rights Agreement
and Co-Sale Agreement.

         SECTION 9.       NO RIGHTS OR LIABILITIES AS STOCKHOLDER.

         Nothing contained in this Warrant shall be construed as conferring
upon the Holder any rights as a stockholder of the Company or as imposing any
liabilities on the Holder to purchase any securities or as a stockholder of the
Company, whether such liabilities are asserted by the Company or by creditors
of the Company.


         The undersigned confirms that the representations and Warranties set
forth in Section 5 of the Purchase Agreement are true and correct in all
material respects as of the date hereof and the exercise date.

                                OPTION AGREEMENT


         This is the OPTION AGREEMENT dated as of November 20, 1997
("Agreement") by and between SCC COMMUNICATIONS CORP. ("SCC"), a Delaware
corporation, and BANC ONE CAPITAL PARTNERS II, LLC ("BOCP"), a Delaware limited
liability company, provided for in and entered into pursuant to the SENIOR
SUBORDINATED NOTE AND WARRANT PURCHASE AGREEMENT dated as of the date hereof,
as amended, restated, supplemented or otherwise modified and in effect from
time to time ("Purchase Agreement"), by and among BOCP, as purchaser, and SCC,
as seller.

         SCC, together with its successors and assigns, is referred to as the
"Company".  BOCP, together with its successors and assigns, is referred to as
the "Holder."  The Company and the Holder are referred to collectively as the
"Parties" and individually as a "Party."

         THIS AGREEMENT IS ONE OF THE "RELATED DOCUMENTS" REFERRED TO IN THE
PURCHASE AGREEMENT.

         In consideration of their mutual promises set forth in this Agreement
and the Purchase Agreement, the Parties hereby agree as follows.


         Section 1.    DEFINITIONS.

                 All capitalized terms not otherwise defined in this Agreement
shall have the definitions set forth in the Glossary of Defined Terms attached
to the Purchase Agreement, which definitions are, to the extent applicable,
incorporated in this Agreement by reference.

         Section 2.    PUT OPTION.

               2.1     PUT OPTION.  At any time after the occurrence of a Put 
Trigger Event and prior to the occurrence of an Initial Public Offering, the
Holder shall have the option to require the Company to purchase from the Holder,
upon the terms and subject to the conditions set forth in this Agreement, all,
but not less than all, of the Warrant Shares and Purchased Shares then owned by
the Holder.  The purchase price for the Warrant Shares and Purchased Shares to
be purchased shall be the Put Price.

               2.2     MANNER OF EXERCISE.  The option provided for in this 
Section ("Put Option") may be exercised by the Holder by giving Notice to the
Company that the Holder elects to exercise such Put Option at the applicable Put
Price and upon the terms and subject to the conditions set forth in this
Agreement.  Such Notice of election by the Holder shall be irrevocable.  Upon
final determination of the applicable Put Price as provided for in this
Agreement, the Company shall be required to purchase all of the Warrant and
Purchased Shares
<PAGE>   4
then owned by the Holder. The Company shall not be obligated to purchase the
Warrant Shares or Purchased Shares then owned by the Holder to the extent that
the Company shall be unable to do so without a breach or violation of the
provisions of Applicable Law or any agreement with respect to its Senior
Indebtedness.  Notwithstanding the foregoing, the Company shall use all
reasonable efforts to remove all limitations upon its ability to purchase the
Warrant Shares or Purchased Shares then owned by the Holder, if any, and such
obligation shall remain a continuing obligation of the Company and the Company
shall purchase the Warrant Shares or Purchased Shares then owned by the Holder
immediately after and to the extent all such limitations have been removed.

               2.3     CLOSING AND PAYMENT.  The closing for the purchase of 
the Warrant Shares and Purchased Shares by the Company pursuant to this
Agreement shall occur within thirty (30)  days following the date of the
determination of the Put Price, which shall be payable by the Company by
delivery of a certified or cashiers' check payable to the Holder against
delivery by the Holder of the Warrant Shares and Purchased Shares.

               2.4     APPOINTMENT OF APPRAISER.  If the appointment of an 
Appraiser is required or permitted in connection with the determination of the
Put Price under this Section 2, then within ten (10) days after the exercise of
the Put Option, the Company and the Holder shall endeavor in good faith to
select a mutually acceptable Appraiser.  If no such Appraiser is mutually
selected within such time period or such longer time period as the Company and
the Holder shall mutually agree upon, then within ten (10) days thereafter, the
Company and the Holder shall each designate an investment banking firm that is
not an Affiliate of either the Company or the Holder, and within (10) ten days
thereafter, such investment banking firms shall mutually select the Appraiser. 
The Company and Holder shall each pay one-half of the reasonable fees and
expenses of the Appraiser, and, if applicable, the Company and the Holder shall
each pay the fees and expenses of the investment banking firm designated by each
of them for the purpose of selecting the Appraiser.

         Section 3.    MISCELLANEOUS.

         The provisions of Section 13 of the Purchase Agreement are applicable
to this Agreement and are, to the extent applicable, incorporated by reference
in this Agreement.

                        REGISTRATION RIGHTS AGREEMENT


         This is the REGISTRATION RIGHTS AGREEMENT, dated as of November 20,
1997 ("Agreement"), by and among SCC COMMUNICATIONS CORP. ("SCC"), a Delaware
corporation, and BANC ONE CAPITAL PARTNERS II, LLC, a Delaware limited
liability company ("BOCP"), provided for and entered into pursuant to the
Senior Subordinated Note and Warrant Purchase Agreement dated as of November
20, 1997,  ("Purchase Agreement") by and between BOCP, as purchaser, and SCC,
as seller.  SCC, together with its successors and assigns, is referred to as
the "Company".  BOCP, together with its successors and assigns, is referred to
as the "Holder".

         THIS AGREEMENT IS ONE OF THE "RELATED DOCUMENTS" REFERRED TO IN THE
PURCHASE AGREEMENT.

         In consideration of their mutual promises set forth in this Agreement
and the Purchase Agreement, the Parties hereby agree as follows:

         SECTION 1.       DEFINITIONS.  All capitalized terms not otherwise
defined in this Agreement shall have the definitions set forth in the Glossary
of Defined Terms attached to the Purchase Agreement which definitions are, to
the extent applicable, incorporated in this Agreement by reference.

         SECTION 2.       REGISTRATION RIGHTS.

                 2.1      DEMAND REGISTRATION.

                 (a)      At any time after the earlier to occur of an Initial
Public offering or November 20, 2003, upon the written request of the Holder
requesting that the Company effect the registration under the Securities Act of
all or part of the Holder's Registrable Securities  (specifying the intended
method of disposition thereof) and whether or not such requested registration
is to be an underwritten offering, the Company will promptly give written
notice of such requested registration to all other holders of Registrable
Securities and thereupon the Company will use its best efforts to effect the
registration under the Securities Act of:

                          (i)     the Registrable Securities which the Company
                 has been so requested to register by the Holder; and

                          (ii)    all other Registrable Securities which the
                 Company has been requested to register by the holders thereof
                 by written request to the Company within thirty (30) days
                 after the date of such written notice by the Company (which
                 request shall specify the intended method of disposition of
                 such Registrable Securities), all to the extent necessary to
                 permit the disposition (in accordance with the intended
                 methods thereof) of the Registrable Securities to be so
                 registered.





<PAGE>   4
                 The Company shall not be required to effect more than one
registration pursuant to request made pursuant to this Section 2.1(a).

                 (b)      Registration of Other Securities.  Whenever the
Company shall effect a registration pursuant to this Section 2.1 in connection
with an underwritten offering, no securities other than Registrable Securities
shall be included among the securities covered by such registration unless (i)
the managing underwriter of such offering shall have advised each holder of
Registrable Securities to be covered by such registration in writing that the
inclusion of such other securities would not adversely affect such offering or
(ii) the holders of all Registrable Securities to be covered by such
registration shall have consented in writing to the inclusion of such other
securities.

                 (c)      Registration Statement Form.  Registrations under
this Section 2.1 shall be on such appropriate registration form as shall be
selected by the Company and as shall  permit the disposition of such
Registrable Securities in accordance with the intended method or methods of
disposition specified in any request for such registration.  The Company agrees
to include in any such registration statement all information which holders of
Registrable Securities being registered shall reasonably request.

                 (d)      Expenses.  The Company will pay all Registration
Expenses in connection with any registration requested pursuant to this Section
2.1.  If a registration begun pursuant to a request made under Section 2.1 is
withdrawn by the holders of the Registrable Securities making such request
because information concerning the Company is disclosed that is materially and
adversely different from the information known to such holders at the time such
request was made, the Company will pay all Registration Expenses in connection
with such request without reducing the number of registrations which the Holder
has a right to cause the Company to effect under Section 2.1 hereof.

                 (e)      Effective Registration Statement.  A registration
requested pursuant to this Section 2.1 shall not be deemed to have been
effected (i) unless a registration statement with respect thereto has become
effective, (ii) if after it has become effective, such registration becomes the
subject of any stop order, injunction or other order or requirement of the
Commission or other governmental agency or court for any reason, or (iii) if
the conditions to closing specified in the purchase agreement or underwriting
agreement entered into in connection with such registration are not satisfied.

                 (f)      Selection of Underwriters.  If a requested
registration pursuant to this Section 2.1 involves an underwritten offering,
the underwriter or underwriters thereof shall be selected by the Company.

                 (g)      Priority in Requested Registrations.  If a requested
registration pursuant to this Section 2.1 involves an underwritten offering,
and the managing underwriter shall advise the





<PAGE>   5
Company in writing that, in its opinion, the number of securities requested to
be included in such registration exceeds the number which can be sold in such
offering within a price range acceptable to the Holder, the Company will so
advise the Holder in writing and will include in such registration first the
number of Registrable Securities held by the Holder that the Company is so
advised can be sold in such offering, and second, such Registrable Securities
requested to be included in such registration by other holders and all other
Capital Stock proposed to be sold by the Company pro rata.

                 2.2      "PIGGYBACK" REGISTRATION.

                 (a)      Right to Include Registrable Securities.  If the
Company at any time proposes to register any of its Capital Stock under the
Securities Act (other than by a registration on Form S-4 or Form S-8 or any
successor or similar form and other than pursuant to Section 2.1), whether or
not for sale for its own account, it will each such time give prompt written
Notice to the Holder.  Upon the written request of the Holder made within 30
days after the receipt of any such Notice (which request shall specify the
Registrable Securities intended to be disposed of by the Holder and the
intended method of disposition thereof), the Company will use its best efforts
to effect the registration under the Securities Act of all Registrable
Securities which the Company has been so requested to register by the Holder,
to the extent necessary to permit the disposition (in accordance with the
intended methods thereof) of the Registrable Securities to be registered.  If,
at any time after giving written notice of its intention to register any
Capital Stock and prior to the effective date of the registration statement
filed in connection with such registration, the Company shall determine for any
reason not to register or to delay registration of such Capital Stock, the
Company may, at its election, give written notice of such determination to each
holder of Registrable Securities and, thereupon, (i) in the case of a
determination not to register, shall be relieved of its obligations to register
any Registrable Securities in connection with such registration (but not from
its obligation to pay the Registration Expenses in connection therewith),
without prejudice, however, to the rights of the Holder to request that such
registration be effected as a registration under Section 2.1 subject to the
terms of that Section, and (ii) in the case of a determination to delay
registration, shall be permitted to delay registering any Registrable
Securities for the same period as the delay in registering such other Capital
Stock.  No registration effected under this Section 2.2 shall relieve the
Company of its obligation to effect any registration under Section 2.1.  The
Company will pay all Registration Expenses in connection with each registration
of Registrable Securities requested pursuant to this Section 2.2.

                 (b)      Priority in Registrations.  If (i) a registration
pursuant to this Section 2.2 involves an underwritten offering of the Capital
Stock, and  (ii) the managing underwriter shall inform the Company and the
holders of the Registrable Securities requesting such registration of its
belief that the number of securities requested to be included in such
registration exceeds the number that can be sold in such offering, then the
Company will include in such registration, to the extent to which the Company
is advised can be sold in  such offering, securities as follows:





<PAGE>   6
                          (1) if such registration is for an offering of
                          Capital Stock for the account of the Company, first,
                          all Capital Stock proposed by the Company to be sold
                          for its own account, second, such Registrable
                          Securities requested by the Holder to be included in
                          such registration, and third, all other Capital Stock
                          of the Company requested to be included in such
                          registration pro rata on the basis of the number of
                          shares of such Capital Stock so requested to be
                          included;

                          (2) if such registration is for other than an
                          offering described in (1), such Registrable
                          Securities requested to be included in such
                          registration and all other Capital Stock proposed by
                          the Company to be sold for its own account shall be
                          included in such registration pro rata on the basis
                          of the number of shares of such Registrable
                          Securities and such other Capital Stock so proposed
                          to be sold.

                 2.3      REGISTRATION PROCEDURES.  If the Company is required
to use its best efforts to effect the registration of any Registrable
Securities as provided in Sections 2.1 and 2.2, the Company will as
expeditiously as possible:

                          (i) prepare and as soon thereafter as reasonably
                 practicable file with the Commission the registration
                 statement to effect such registration and thereafter use its
                 best efforts to cause such registration statement to become
                 effective, provided that the Company may discontinue any
                 registration of its Capital Stock which are not Registrable
                 Securities (and, under the circumstances specified in Section
                 2.2(a), its securities which are Registrable Securities) at
                 any time prior to the effective date of the registration
                 statement relating thereto;

                          (ii) prepare and file with the Commission such
                 amendments and supplements to such registration statement and
                 the prospectus used in connection therewith as may be
                 necessary to keep such registration statement effective and to
                 comply with the provisions of the Securities Act with respect
                 to the disposition of all Capital Stock covered by such
                 registration statement until such time as all of such
                 securities have been disposed of in accordance with the
                 intended methods of disposition by the Holder set forth in
                 such registration statement;

                          (iii) furnish to Holder such number of prospectuses
                 and copies of each such amendment and supplement thereto and
                 such other documents as Holder may reasonably request;

                          (iv) use its best efforts to register or qualify all
                 Registrable Securities and other Capital Stock covered by such
                 registration statement under such other securities or blue sky
                 laws of such jurisdictions as the Holder shall reasonably





<PAGE>   7
                 request, to keep such registration or qualification in effect
                 for so long as such registration statement remains in effect,
                 and take any other action which may be reasonably necessary or
                 advisable to enable the Holder to consummate the disposition
                 in such jurisdictions of the securities owned by the Holder,
                 except that the Company shall not for any such purpose be
                 required to qualify generally to do business as a foreign
                 corporation in any jurisdiction wherein it would not but for
                 the requirements of this subdivision (iv) be obligated to be
                 so qualified or to consent to general service of process in
                 any such jurisdiction;

                          (v) use its best efforts to cause all Registrable
                 Securities covered by such registration statement to be
                 registered with or approved by such other governmental
                 agencies or authorities as may be necessary to enable the
                 Holder to consummate the disposition of such Registrable
                 Securities;

                          (vi) furnish to the Holder a signed counterpart,
                 addressed to the Holder (and underwriters, if any) of:

                                  (1) an opinion of counsel for the Company,
                                  dated the effective date of such registration
                                  statement (and, if such registration includes
                                  an underwritten public offering, dated the
                                  date of the closing under the underwriting
                                  agreement), reasonably satisfactory in form
                                  and substance to the Holder, and

                                  (2) a "comfort" letter, dated the effective
                                  date of such registration statement (and, if
                                  such registration includes an underwritten
                                  public offering, dated the date of the
                                  closing under the underwriting agreement),
                                  signed by the independent public accountants
                                  who have certified the Company's financial
                                  statements included in such registration
                                  statement,

                                  covering substantially the same matters as
                                  are customarily covered in opinions of
                                  issuer's counsel and in accountants' letters
                                  delivered to the underwriters in underwritten
                                  public offerings and such other matters as
                                  the Holder may reasonably request;

                          (vii) notify Holder upon discovery that, or upon the
                 happening of any event as a result of which, the prospectus
                 included in such registration statement includes an untrue
                 statement of any material fact or omits to state any material
                 fact required to be stated therein or necessary to make the
                 statements therein not misleading in the light of the
                 circumstances under which they were made, and at





<PAGE>   8
                 the request of the Holder promptly prepare and furnish to
                 Holder a reasonable number of copies of a supplement to or an
                 amendment to such prospectus as may be necessary;

                          (viii) otherwise use its best efforts to comply with
                 all applicable rules and regulations of the Commission, and
                 furnish to Holder prior to the filing thereof a copy of any
                 amendment or supplement to such registration statement or
                 prospectus;

                          (ix) provide and cause to be maintained a transfer
                 agent and registrar for all Registrable Securities covered by
                 such registration statement from and after a date not later
                 than the effective date of such registration statement;

                          (x) use its best efforts to list all Registrable
                 Securities covered by such registration statement on any
                 securities exchange on which any of the Registrable Securities
                 is then listed; and

                          (xi) enter into such agreements and take such other
                 actions as the Holder shall reasonably request in order to
                 expedite or facilitate the disposition of such Registrable
                 Securities.

         The Company many require the Holder to furnish the Company such
information regarding the Holder and the distribution of such securities as the
Company may from time to time reasonably request in writing.

         Holder  agrees that upon receipt of any Notice from the Company of the
happening of any event of the kind described in the subdivision (vii) of this
Section 2.3, the Holder will forthwith discontinue the disposition of
Registrable Securities pursuant to the registration statement until Holder's
receipt of the copies of the supplemented or amended prospectus contemplated by
subdivision (vii) of this Section 2.3 and, if so directed by the Company, will
destroy all copies, other than permanent file copies, then in Holder's
possession of the prospectus relating to such Registrable Securities.

                 2.4      UNDERWRITTEN OFFERINGS.

                 (a)      Demand Underwritten Offerings.  If requested by the
underwriters for any underwritten offering, the Company will enter into an
underwriting agreement with such underwriters, such agreement to be
satisfactory is substance and form to the Company and the underwriters and to
contain such terms as are generally prevailing in agreements of this type. If
the Holder is a party to such underwriting agreement it may, at its option,
require that any or all of the representations and warranties by, and the other
agreements on the part of, the Company to and for the benefit of such
underwriters shall also be made to and for the benefit of the Holder.  Holder
shall not be required to make any representations and warranties to or
agreements with





<PAGE>   9
the Company or the underwriters other than representations, warranties or
agreements regarding the Holder, the Holder's Registrable Securities and the
Holder's intended method of distribution and any other representation required
by law.

                 (b)      Piggyback Underwritten Offerings.  If the Company at
any time proposes to register any of its Capital Stock as contemplated by
Section 2.2 and such securities are to be distributed by or through one or more
underwriters, the Company will, if requested by the Holder, arrange for such
underwriters to include all the Registrable Securities to be offered and sold
by the Holder among the securities to be distributed to such underwriters.  The
Holder shall be a party to the underwriting agreement and may, at its option,
require that any or all of the representations and warranties by, and the other
agreements on the part of, the Company to and for the benefit of such
underwriters shall also be made to and for the benefit of the Holder.  Holder
shall not be required to make any representations or warranties to or agreement
with the Company or the underwriters other than representations, warranties or
agreements regarding the Holder, the Holder's Registrable Securities and the
Holder's intended method of distribution and any other representation required
by law.

                 2.5      INDEMNIFICATION.

                 (a)      Indemnification by the Company.  In the event of any
registration pursuant to Section 2.1 or 2.2, the Company will, and hereby does,
indemnify and hold harmless the Holder, its directors, partners, members and
officers, each other Person who participates as an underwriter in the offering
on behalf of the Holder and each other Person, if any, who controls such seller
or underwriter within the meaning of the Securities Act, against any losses,
claims, damages or liabilities, joint or several, to which any one of them may
become subject under the Securities Act or otherwise, and the Company will
reimburse the Holder and each other Person for any legal or any other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, liability, action or proceeding; provided that (i) the
Company shall not be liable in any such case to the extent that any such loss,
claim, damage, liability (or action or proceeding in respect thereof) or
expenses arises out of or is based upon any statement or material omission
furnished in writing to the Company by the Holder or other Person in connection
with the preparation of the registration statement, and (ii) the Company shall
not be liable to any Person who participates as an underwriter or any other
Person who controls such underwriter within the meaning of the Securities Act,
to the extent that any such loss, claim, damage, liability (or action or
proceeding in respect thereof) or expense arise out of such Person's failure to
provide a copy of the final prospectus, as the same may be then supplemented or
amended, to the purchaser at or prior to the written confirmation of the sale
of Registrable Securities, if such final prospectus differs from the
preliminary prospectus.  Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of the Holder or other
Person and shall survive the transfer of such securities by the Holder.

                 (b)      Indemnification by the Holder.  The Company may
require, as a condition to including any Registrable Securities in any
registration statement filed pursuant to Section 2.1 or 2.2,





<PAGE>   10
that the Company shall have received an undertaking satisfactory to it from the
Holder to indemnify and hold harmless (in the same manner and to the same
extent as set forth in subdivision (a) of this Section 2.5) the Company, each
director and officer of the Company and each other Person, if any, who controls
the Company within the meaning of the Securities Act, with respect to any
statement, or alleged statement in or omission or alleged omission from such
registration statement, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, if such
statement or alleged statement or omission or alleged omission was made in
reliance upon and in conformity with written information furnished to the
Company by the Holder specifically stating that it is for use in preparation of
such registration statement.  Such indemnity shall remain in full force and
effect, regardless of any investigation made by or on behalf of the Company or
any such director, officer or controlling Person and shall survive the transfer
of such Registrable Securities by the Holder.  Notwithstanding the foregoing,
the aggregate liability of any Holder for any indemnification under this
Section 2.5(b) shall be limited to the aggregate net proceeds received by the
Holder from the sale of Registrable Securities pursuant to such registration
statement.

                 (c)      Notices of Claims, etc.  Promptly after receipt by an
indemnified party of Notice of the commencement of any action or proceeding
involving a claim referred to in the preceding subdivisions of this Section
2.5, such indemnified party will, if a claim in respect thereof is to be made
against an indemnifying party, give written Notice to the latter of the
commencement of such action, provided that the failure of any indemnified party
to give Notice as provided herein shall not relieve the indemnifying party of
its obligation under the preceding subdivisions of this Section 2.5, except to
the extent that the indemnifying party is actually prejudiced by such failure.
Unless in such indemnified party's reasonable judgment a conflict of interest
between such indemnified and indemnifying party may exist in respect of such
claim, the indemnifying party shall be entitled to participate in and to assume
the defense thereof, jointly with any other indemnifying party, with counsel
reasonably satisfactory to such indemnified party.  After Notice from the
indemnifying party of its election to assume the defense, the indemnifying
party shall not be liable to such indemnified party for any legal or other
expenses subsequently incurred by the latter in connection with the defense
thereof other than reasonable costs of investigation.  No indemnifying party
shall, without the consent of the indemnified party, consent to entry of any
judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect to such claim or
litigation.

                 2.6      ADJUSTMENTS AFFECTING REGISTRABLE SECURITIES.  The
Company will not effect or permit to occur any combination or subdivision of
Registrable Securities which would adversely affect the ability of the Holder
to include such Registrable Securities in any registration  contemplated by
this Section 2 or the marketability of such Registrable Securities under any
such registration.

         SECTION 3.       RULE 144. If the Company shall have filed a
registration statement, the Company will file the reports required to be filed
by it under the Securities Act and the Securities





<PAGE>   11
Exchange Act and the rules and regulations adopted by the Commission thereunder
(or, if the Company is not required to file such reports, will, upon the
request of any Holder, make publicly available other information) and will take
such further action as such Holder may reasonably request, all to the extent
required from time to time to enable such Holder to sell Registrable Securities
without registration under the Securities Act within the limitation of the
exemptions provided by (a) Rule 144 under the Securities Act, as such Rule may
be amended from time to time or (b) any similar rule or regulation hereafter
adopted by the Commission.

         SECTION 4.       INFORMATION REQUIRED BY RULE 144A.  The Company
covenants that it will, upon the request of the Holder, provide the Holder, and
any institutional investor designated by such Holder, such financial and other
information as such Holder may reasonably determine to be necessary in order to
permit the Holder's compliance with the informational requirements of Rule 144A
under the Securities Act in connection with the resale of any Registrable
Securities, except at such time as the Company is subject to the reporting
requirements of Section 13 or 15(d) of the Securities Exchange Act.

         SECTION 5.       COVENANTS.  The Company covenants and agrees that:

                 (a)      it shall not sell any shares of the Capital Stock of
the Company except in an offering subject to (i) registration under the
Securities Act, and (ii) the terms of this Agreement;

                 (b)      it shall not participate in or cooperate with any
offering of the Capital Stock of the Company, either directly or indirectly, by
any shareholder of the Company under Regulation S of the Securities Act; and

                 (c)      no other shareholder of the Company owns any share of
Capital Stock which has registration rights, and the Company shall not, without
the prior written consent of Holder, which may be withheld in it sole
discretion, grant registration rights to any Person.

         SECTION 6.       TERMINATION OF REGISTRATION RIGHTS.  The registration
rights granted pursuant to this Agreement shall terminate at the earlier of (i)
the time neither the Holder nor any Affiliate of the Holder owns any of the
Capital Stock of the Company, or (ii) all shares of Capital Stock of the
Company held by the Holder or any affiliate thereof can be sold pursuant to
Rule 144(k), provided, however, that the average weekly reported volume of
trading in such securities on all national securities exchanges and/or reported
through the automated quotation system of a registered securities association
for the past twelve months is greater than one percent of the class of shares
so registered.

         SECTION 7.       SPECIFIC PERFORMANCE.  The Parties recognize and
agree that money damages may be insufficient to compensate the Holder for
breaches by the Company of terms hereof and, consequently, that the equitable
remedy of specific performance of the terms hereof will be available in the
event of any such breach





<PAGE>   12

         SECTION 8.       MISCELLANEOUS.

         The provisions of Section 13 of the Purchase Agreement are applicable
to this Agreement and are, to the extent applicable, incorporated by reference
in this Agreement.

         IN WITNESS WHEREOF, the parties have caused the Agreement to be
executed and delivered by their respective officers thereunto duly authorized
as of the date first above written.

                               CO-SALE AGREEMENT


       This is a CO-SALE AGREEMENT dated as of November 20, 1997 ("Agreement")
by and among SCC COMMUNICATIONS CORP. ("SCC"), a Delaware corporation, GEORGE
K. HEINRICHS, JOHN SIMS, NANCY HAMILTON, THE HILL PARTNERSHIP III, A LIMITED
PARTNERSHIP, AMERITECH DEVELOPMENT CORPORATION AND BOSTON CAPITAL VENTURES
LIMITED PARTNERSHIP and BANC ONE CAPITAL PARTNERS II, LLC ("BOCP"), a Delaware
limited liability company, provided for in and entered into pursuant to the
SENIOR SUBORDINATED NOTE AND WARRANT PURCHASE AGREEMENT dated the date hereof,
as amended, restated, supplemented or otherwise modified from time to time
("Purchase Agreement") by and between BOCP, as purchaser, and SCC, as seller.

       ASI, together with its successors and assigns, is referred to as the
"Company."  The individuals named in the first paragraph hereof, together with
their respective successors and assigns, are referred to individually as a
"Shareholder" and collectively as the "Shareholders," and BOCP, together with
its successors and assigns, is referred to as the "Holder."  The Company, the
Shareholders and the Holder are referred to collectively as the "Parties" and
individually as a "Party."

       THIS AGREEMENT IS ONE OF THE "RELATED DOCUMENTS" REFERRED TO IN THE
PURCHASE AGREEMENT.

       In consideration of their mutual promises set forth in this Agreement
and the Purchase Agreement, the Parties hereby agree as follows.

       SECTION 1.    DEFINITIONS

All capitalized terms not otherwise defined in this Agreement shall have the
definitions set forth in the Glossary of Defined Terms attached to the Purchase
Agreement, which definitions are, to the extent applicable, incorporated in
this Agreement by reference.

       SECTION 2.    SALES BY SHAREHOLDERS.

              2.1    NOTICE OF PURCHASER OFFERS.   Should one or more
Shareholders propose to accept one or more Purchase Offers, then each such
Shareholder shall promptly notify the Holder of the terms and conditions of
such Purchase Offer.

              2.2    RIGHT TO PARTICIPATE.  The Holder shall have the right,
exercisable upon written Notice to such selling Shareholder within fifteen (15)
Business Days after receipt of the notice of the Purchase Offer, to participate
in such selling Shareholder's sale of Common Shares or Convertible Securities
on the same (or, in the case of Convertible Securities, equivalent) terms



                                       1
<PAGE>   4
and conditions.  To the extent that the Holder exercises such right of
participation, the number of Common Shares or Convertible Securities which such
selling Shareholder may sell pursuant to such Purchase Offer shall be
correspondingly reduced.  The right of participation of the Holder shall be
subject to the following terms and conditions:

              (a)    The Holder may sell all or any part of that number of
Holder's Shares  equal to the product obtained by multiplying (i) the aggregate
number of Common Shares (including the Common Share equivalent of any
Convertible Securities) covered by the Purchase Offer by (ii) a fraction (A)
the numerator of which is the number of Holder's Shares at the time owned by
the Holder, and (B) the denominator of which is the sum of (x) the number of
such Common Shares (including the Common Share equivalent of Convertible
Securities) at the time owned by the Selling Shareholder, and (y) the number of
Holder's Shares at that time owned by the Holder.  For purposes of making such
computation, the Holder shall be deemed to own the number of Common Shares as
if its Warrant Shares had been converted into Common Shares.

              (b)    The Holder may participate in the sale by (i) exercising
the Warrant in accordance with its terms, if Warrant Shares are to be sold, and
(ii) delivering to the selling Shareholder for transfer to the purchase offeror
one or more certificates, properly endorsed for transfer, free and clear of all
adverse claims, which represent that number of Holder's Shares which the Holder
elects to sell pursuant to this Section 2.2.

              2.3    CONSUMMATION OF SALE.  The stock certificate or
certificates which Holder delivers to the Selling Shareholder pursuant to
Section 2.2 shall be transferred by the selling Shareholder to the purchase
offeror in consummation of the sale pursuant to the terms and conditions
specified in the Section 2.1 Notice to the Holder, and such Selling Shareholder
shall promptly thereafter remit to the Holder that portion of the sale proceeds
to which the Holder is entitled by reason of its participation in such sale.

              2.4    ONGOING RIGHTS.  The exercise or non-exercise of the
rights of the Holder pursuant to Section 2.1 hereof to participate in one or
more sales made by any selling Shareholder shall not adversely affect the
Holder's right to participate in subsequent sales by any selling Shareholder.

              2.5    PERMITTED EXEMPTIONS.  The participation rights of the
Holder shall not apply to (i) any bona fide gift, transfers to family members
or trusts established for the benefit thereof, or transfers upon death or
disability; provided that a Shareholder shall inform the Holder of such gift
prior to effecting it and the donee shall furnish the Holder with a written
agreement to be bound by, and comply with, all provisions of this Agreement
applicable to such Shareholder; (ii) the sale of up to 200,000 Common Shares,
in the aggregate, by George K. Heinrichs, John Sims and Nancy Hamilton; and
(iii), the sale or transfer of Common Shares to partners, stockholders or
affiliates of a Shareholder.


                                       2
<PAGE>   5
       SECTION 3.    PROHIBITED TRANSFERS.

              3.1    TREATMENT OF PROHIBITED TRANSFERS.  In the event a
Shareholder should engage in a Prohibited Transfer, the Holder, in addition to
such other remedies as may be available at law, in equity or hereunder, shall
have the put option provided in Section 3.2.

              3.2    PUT OPTION.  In the event of a Prohibited Transfer, the
Holder shall have the right to sell to the Shareholder engaging in such
Prohibited Transfer that number of Common Shares or Convertible Securities
owned by the Holder equal to the number of shares the Holder would have been
entitled to transfer to the purchase offeror in the Prohibited Transfer
pursuant to the terms hereof.  Such sale shall be made on the following terms
and conditions:

              (a)    The price per share at which such Common Shares or
Convertible Securities are to be sold to the Shareholder shall be equal or
equivalent to the price per share paid by the purchase offeror to the
Shareholder in the Prohibited Transfer.  The Shareholder shall also reimburse
the Holder for any and all reasonable fees and expenses, including legal fees
and expenses, incurred pursuant to the exercise or the attempted exercise of
the Holder's rights under this Section 3.

              (b)    Within thirty (30) days after the earlier of the date on
which the Holder (i) receives Notice from a Shareholder of a Prohibited
Transfer, or (ii) otherwise becomes aware of a Prohibited Transfer, the Holder
shall, if exercising the put option created hereby, deliver to such Shareholder
the certificate or certificates representing Common Shares or Convertible
Securities to be sold hereunder, each certificate to be properly endorsed for
transfer.

              (c)    Such Shareholder shall, upon receipt of the certificate or
certificates for the Common Shares or Convertible Securities to be sold by a
Holder pursuant to Section 3.2, free and clear of all adverse claims, pay the
aggregate purchase price therefor and the amount of reimbursable fees and
expenses, as specified in Section 3.2(a), by certified or cashier's check made
payable to the order of the Holder.

              (d)    Notwithstanding the foregoing, any attempt to Transfer
shares of the Company in violation of the terms of this Agreement shall be void
and the Company agrees it will not effect such a Transfer nor will it treat any
alleged transferee as the holder of such Securities without the written consent
of the Holder.

       SECTION 4.    LEGENDED CERTIFICATE.

              4.1    LEGEND.  Each certificate representing Common Shares now
or hereafter


                                       3
<PAGE>   6
owned by any Shareholder shall be endorsed with the following legend:

       THE SALE OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE
       IS SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN CO-SALE AGREEMENT BY
       AND BETWEEN THE SHAREHOLDER, THE COMPANY AND BANC ONE CAPITAL PARTNERS
       II, LLC.  COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST
       TO THE SECRETARY OF THE COMPANY.

              4.2    LEGEND REMOVAL.  The Section 4.1 legend shall be removed
upon the earlier of the termination of this Agreement or the date upon which
the provisions of this Agreement are no longer applicable to such shares in
accordance with the provisions of Section 5.

       SECTION 5.    TERMINATION OF CO-SALE RIGHTS.

       The rights of the Holder under this Agreement and the obligations of the
Shareholders with respect to the Holder shall terminate at such time as BOCP or
any of its Affiliates does not own any Common Shares. Unless sooner terminated
in accordance with the preceding sentence, this Agreement shall terminate upon
the occurrence of the earliest to occur of any of the following events:

              (a)    The liquidation, dissolution or indefinite cessation of
the business operations of the Company;

              (b)    The execution by the Company of a general assignment for
the benefit of creditors or the appointment of a receiver or trustee to take
possession of the property and assets of the Company;

              (c)    The consummation of an Initial Public Offering; or

              (d)    The consummation of a Disposition.

       SECTION 6.    OTHER OBLIGATIONS OF COMPANY.

       The Company agrees to use all reasonable efforts to enforce the terms of
this Agreement, to inform the Holder of any breach hereof and to assist the
Holder in the exercise of its rights and performance of its obligations under
Section 3 hereof.

       SECTION 7.    MISCELLANEOUS.

                          TERMS AND CONDITIONS OF LEASE

         Lessee (which term shall include the co-Lessee, whose obligations
hereunder shall be joint and several with those of Lessee) and Lessor agree and
acknowledge that this Master Lease (the Lease) is being executed in conjunction
with one or more written schedules (Supplementary Schedules) which, by specific
reference to this Lease and upon execution by Lessee and Lessor, become subject
to all the terms and conditions contained herein.  The Equipment that is the
subject of this Lease, is described on the Supplementary Schedules and shall
further include, without limitation, such other items, though not specifically
identified on such Supplementary Schedules, as relate to the Equipment and are
financed by Lessor, such as wiring.  Upon such execution of a Supplementary
Schedule, any and all additional or specific terms and conditions therein shall
be, with respect to such Supplementary Schedule, incorporated herein and shall
have the same force and effect as if such terms and conditions were expressly
set forth herein.  The terms and conditions contained herein shall apply to
each Supplementary Schedule that is properly executed and made subject to such
terms and conditions, as if a separate Lease were executed for each
Supplementary Schedule.  The invalidation, fulfillment, waiver, termination, or
other disposition of any rights or obligations of either the Lessee or Lessor
or both of them arising from the execution of this Lease in conjunction with
any one Supplementary Schedule shall not affect the status of the rights or
obligations of either or both of those parties arising from the execution of
this Lease in conjunction with any other Supplementary Schedule, except in the
event of default by Lessee as provided in Section 14 herein.  The parties agree
that this Lease is a Finance Lease as defined by Section 2A-103(g) of the
Uniform Commercial Code.

         Subsequent wording of this Lease notwithstanding, this Lease is
effective with respect to any Supplementary Schedule executed in conjunction
herewith for the lease term (as subsequently defined herein) provided in such
Supplementary Schedule.  Additional Supplementary Schedules may be executed
from time to time by the Lessee and the Lessor, and if such Supplementary
Schedules refer by date and contracting parties to this Lease, such
Supplementary Schedules shall be deemed to be executed in conjunction herewith
and to be subject hereto regardless of the date upon which such Supplementary
Schedules are executed and notwithstanding that a prior period of effectiveness
hereof has lapsed through termination of all previous lease terms.

         Lessor hereby leases to Lessee and Lessee hereby hires from Lessor the
Equipment described on any Supplementary Schedules executed in conjunction
herewith and declared to be and to constitute a part of the Equipment leased
hereunder (such Equipment together with all parts, replacements, repairs,
additions, and accessories incorporated therein and/or affixed thereto
hereinafter referred to as the Equipment) on the terms and conditions set forth
herein and in such Supplementary Schedules.  If more than one Lessee is named
in this Lease, the liability of each named Lessee shall be joint and several.
Because the Equipment may include not only tangible property but also the right
to use technology and/or the right to receive services, it is understood that
the term 'Equipment' covers all of the following: hardware, printers, modems,
cables, peripherals and other tangible
<PAGE>   2
equipment, all documentation, such as technical documentation or user manuals,
operating system software (object and/or source code form), application software
(object and/or source code form) and other technologies, training aids such as
training manuals, training software, and training videotapes; data, databases,
bulletin boards and other collections of information, in tangible or intangible
form; and installation, training, conversion, customization, development,
support, maintenance, and other services, as more specifically described in this
Lease or in any Supplementary Schedule.  Further, the term 'lease,' whenever it
is used as a noun in the Lease with reference to the technology or other
intangible properties that are part of the Equipment, shall be deemed to mean,
assignment and/or sub-license of all of Lessor's license to or interest in, and
rights to use, such technology and properties; whenever it is so used with
reference to benefits or services, it shall be deemed to mean, assignment of all
of Lessor's rights to receive such benefits and services. ('To lease,' or any
other inflectional form of its usage as a verb, shall mean 'to sublicense' or
'to assign' (as the context may require), or the appropriate inflectional form
thereof.)

         1.      LEASE TERM.  The lease term is the period of time which
includes the lease term as specified in the block so entitled on Supplementary
Schedules executed hereunder from time to time.  The lease term commences on
the earlier of: the date the Equipment is accepted by the Lessee, or the date
designated as the billing date on the first rental invoice received by, or as
mutually agreed upon by Lessor and Lessee ('Lease Commencement Date').

         2.      NO WARRANTIES.  LESSEE ACKNOWLEDGES THAT LESSOR IS NOT THE
MANUFACTURER OR LICENSOR, THE AGENT OF THE MANUFACTURER OR LICENSOR, OR THE
DISTRIBUTOR OF THE EQUIPMENT.  LESSEE AGREES THAT LESSOR HAS NOT MADE AND MAKES
NO REPRESENTATIONS OR WARRANTIES OF WHATSOEVER NATURE DIRECTLY OR INDIRECTLY,
EXPRESS OR IMPLIED, AS TO THE SUITABILITY, DURABILITY, FITNESS FOR USE,
MERCHANTABILITY, CONDITION, OR QUALITY OF THE EQUIP AND OF ANY UNIT THEREOF.
LESSEE SPECIFICALLY WAIVES ALL RIGHTS TO CLAIM AGAINST LESSOR AND ANY ASSIGNEES
OF LESSOR FOR BREACH OF ANY WARRANTY OF ANY KIND WHATSOEVER; AND WITH RESPECT
TO LESSOR OR LESSOR'S ASSIGNEE, LESSEE LEASES EQUIPMENT "AS IS".  LESSOR AND
LESSOR'S ASSIGNEE SHALL NOT BE LIABLE TO LESSEE FOR ANY LOSS, DAMAGE OR EXPENSE
OF ANY KIND OR NATURE CAUSED DIRECTLY OR INDIRECTLY BY ANY EQUIPMENT LEASED
HEREUNDER, OR BY THE USE OR MAINTENANCE THEREOF, OR BY THE REPAIRS SERVICE, OR
ADJUSTMENT THERETO OR ANY DELAY OR FAILURE TO PROVIDE ANY THEREOF, OR BY ANY
INTERRUPTION OF SERVICE OR LOSS OF USE THEREOF, OR FOR ANY LOSS OF BUSINESS OR
DAMAGE WHATSOEVER AND HOWSOEVER CAUSED.  WITHOUT IN ANY WAY IMPLYING THAT ANY
SUCH WARRANTY EXISTS AND WITHOUT MAKING ANY REPRESENTATIONS AS TO THE EXTENT OF
ANY SUCH WARRANTY, LESSOR AGREES, TO THE EXTENT OF ITS LEGAL POWER TO MAKE SUCH
ASSIGNMENT AND WITHOUT INCREASING IT'S LIABILITY HIEREUNDER, TO ASSIGN TO
LESSEE UPON LESSEE'S REQUEST THEREFOR ANY WARRANTY OF A MANUFACTURER OR
LICENSOR OR SELLER RELANNG TO THE EQUIPMENT THAT MAY HAVE BEEN GIVEN TO LESSOR.

THE ADDMONAL PROVISIONS OF THIS LEASE ARE INCLUDED IN AND MADE A PART OF THIS
LEASE, WHICH LESSEE ACKNOWLEDGES THAT IT HAS READ.  WITH RESPECT TO ANY
SUPPLEMENTARY SCHEDULE EXECUTED IN CONJUNCTION HEREWITH, THIS IS A NON-
CANCELLABLE LEASE FOR THE LEASE TERM INDICATED ON THIS SUPPLEMENTARY SCHEDULE
AND ANY RENEWAL TERM(S).

         3.      RENT.  During the Term of Lease, Lessee agrees to pay Lessor
total rent equal in amount to the number of rent payments specified in the
Supplementary Schedules multiplied by the amount of each rent payment specified
therein.  Lessee shall make rental payments in the amount and on the due dates
specified in the Supplementary Schedules until the total rent and all other
amounts due under the Lease have been paid in full.  If the Lease Commencement
Date is other than the first day of a month, Lessee shall make an initial
payment on the Lease Commencement Date in an amount equal to one-thirtieth of
the rental payments specified in the Supplementary Schedules for each day from
the Lease Commencement Date (including the Lease Commencement
<PAGE>   3
Date) through the last day of such month (including that day).  Any amounts
received by Lessor from the Lessee in excess of rental and any other sums
required to be paid by the Lessee shall be held as non-interest bearing security
for Lessee's faithful performance of the conditions of this Lease or any
Supplementary Schedule.  All rental payments shall be paid to the Lessor at the
address stated above or such other place as the Lessor or its assigns may
hereafter direct.  Lessee's obligation to pay rent shall not be abated, reduced
or subject to offset or diminished as a result of any event, including without
limitation damage, destruction, defect, malfunction, loss of use, or
obsolescence of the Equipment, or any other event, except such as is
specifically provided for in Section 9 of this Lease.  The lease payments shall
be adjusted proportionately upward or downward if the actual cost of the
Equipment exceeds or is less than the estimate (original proposal or Equipment
Agreement), and in that event the Lessee authorizes Lessor to adjust the lease
payments upward or downward not to exceed twenty percent (20%).


         4.      SELECTION OF EQUIPMENT. Lessee requests Lessor to purchase or
to cause to be purchased (or, in the case of technology or services, obtain the
appropriate license or contract for) Equipment of the type and quantity
specified in the Supplementary Schedules and has selected the supplier named
therein.  By its execution and delivery of each Supplementary Schedule, hereby
(a) consents and agrees to all of the terms and conditions of any such
purchases, licenses or contracts whereby Lessor acquires any or all of the
Equipment, (b) assigns and transfers to Lessor all Lessee's right, title and
interest in and to any purchase order, license, contract or arrangement entered
into by with any supplier for the Equipment, (c) promises and agrees to perform
all of the duties and obligations of Lessee and/or Lessor under any and all
such purchases, licenses, contracts or arrangements with the suppliers of the
Equipment and (d) confirms that to the extent of any inconsistency between the
provisions of this Lease and the provisions of any such purchase order or
arrangement, the provisions of this Lease shall govern.  Lessee has reviewed
and approved any written supply contract (as defined by section 2A-103(y) of
the Uniform Commercial Code) or purchase order or contract covering the
Equipment purchased.  Lessor is not and shall not be liable for specific
performance of this Lease or for damages if for any reason the supplier delays
or fails to fill the order or if the Lessee negotiates in bad faith prior to
payment by Lessor to the supplier.  Any delay in delivery by the supplier shall
not affect the validity of this Lease.  Lessee acknowledges that neither its
dissatisfaction with any unit of Equipment, nor the failure of any unit of
Equipment to remain in useful condition for the term of this Lease, nor the
termination of any contract with a supplier regarding the Equipment, nor the
loss of possession or the right of possession of the Equipment or any part
thereof by the, shall relieve Lessee from the obligations under this Lease.
Lessee shall have no right, title or interest in or to the Equipment except the
right to use the same upon the terms and conditions herein contained.  The
Equipment shall remain the sole and exclusive personal property of Lessor and
not be deemed a fixture whether or not it becomes attached to any real
property.  Any labels supplied by Lessor to Lessee describing the ownership of
the Equipment shall be affixed by Lessee upon a prominent place on each item of
Equipment.

         5.      PURCHASE AND RENEWAL OPTION; LOCATION AND SURRENDER OF
EQUIPMENT. (a) Prior to the expiration of the initial term hereof, Lessee shall
have the option to: (i) renew this Lease, or (ii) purchase the Equipment for
cash upon the last business day on or prior to the expiration of the lease term
therefor for a price equal to the amount set forth in the Supplementary
Schedule.  If the Fair Market Value Purchase Option was selected on the
Supplementary Schedule, the fair market value shall be determined on the basis
of and shall be equal in amount to, the value which would be obtained in an
arms-length transaction between an informed and willing buyer-user (other than
a used Equipment dealer), who would be retaining the Equipment as part of its
current operations, in continuing and consistent use, and an informed and
willing seller under no compulsion to sell and, in such determination, costs of
removal from the location of current use shall not be a deduction from such
value.  If Lessee desires to exercise either option, it shall give to Lessor
irrevocable written notice of its intention to exercise option at least 120
days (and not more than 180 days) before the expiration of such lease term.  In
the event that Lessee exercises the purchase option described herein, upon
payment by Lessee to Lessor of the purchase price for the Equipment, together
with all rent and any other amounts owing to Lessor hereunder, Lessor shall
transfer to Lessee without any representation or warranty of any kind, express
or implied, title to such Equipment.  Notwithstanding anything herein to the
contrary, if Lessee fails to notify Lessor of its intent with respect to the
exercise or the Options described in this Section 5 within the time frames
contemplated hereby, this Lease shall automatically be renewed for an
additional ninety (90) day period(s) upon the same terms and conditions.  Any
<PAGE>   4
notice of termination during an automatic extension shall be effective on the
last day of the month ninety (90) days after the receipt of such notice.

         (b)     The Equipment shall be delivered to and thereafter kept at the
location specified in the Supplementary Schedules and shall not be removed
therefrom without Lessors prior written consent.  Upon the expiration or
earlier termination of this Lease, Lessee at its cost and expense, shall
immediately return the Equipment to Lessor in good repair, working order, with
unblemished physical appearance and with no defects which affect the operation
or performance of the Equipment ("Return Condition").  Return Condition also
indicates that the Equipment will be eligible at termination of this Agreement
for acceptance by the manufacturer, or a manufacturer certified third party
maintenance organization approved by Lessor, under contract maintenance at the
above mentioned organizations then standard rates.  If the Equipment is not in
Return Condition, Lessee shall remain liable for any and all reasonable costs
required to restore the Equipment including, without limitation, service
records and user manuals properly packed, subject to Lessor's instructions,
adequately insured at no less than its maximum insurable value, to the address
specified by Lessor.  The deinstallation of the Equipment shall be performed by

Notwithstanding the foregoing, Lessor shall have the right, without notice or
demand, to enter Lessee's premises or any other premises where the Equipment
may be found and to take possession of and to remove the Equipment without

and a hearing prior to repossession of the Equipment.  As an inducement to
Lessor and its Assigns to enter into this transaction, Lessee hereby expressly
waives all rights conferred by Rating or future law to notice and a hearing
prior to such repossession by Lessor, its Assigns, or any officer authorized by
law to effect repossession and hereby releases Lessor and its Assigns from all
liability in connection with such repossession.  Lessee's obligation to return
the Equipment may, at Lessors option be specifically enforced by Lessor.

the operation of the Equipment.  Lessee at its expense shall take good and
proper care of the Equipment and make all repairs and replacements to
maintain and preserve the Equipment and keep it in good order and condition.
Unless Lessor shall otherwise consent in writing, shall, at its own expense,

maintenance organization approved by Lessor covering maintenance of each unit
of Equipment. Lessee shall furnish Lessor with a copy of such contract.  Lessee
shall pay all costs to install and dismantle the Equipment. Lessee shall not
make any alterations, additions, or improvements, or add attachments to the
Equipment without the prior written consent of Lessor, except for (i) additions
or attachments to the Equipment consisting solely of telephone terminal
Equipment and (ii) additions or attachments to the Equipment purchased by
Lessee from the original supplier of the Equipment or any other person, or
entity, approved by Lessor.  If desires to lease any such additions or
attachments, Lessee hereby grants to Lessor the right of first refusal to
provide such lease financing to Lessee for such items.  Subject to the
provisions of Section 5(b) hereof, Lessee agrees to restore the Equipment to
Return Condition prior to its return to the Lessor and Lessee agrees that any
addition, alteration, improvement or attachment shall belong to and become a
part of the property of Lessor.  Any software upgrade will become the property
of the Lessor, and Lessee hereby represents and warrants to Lessor, that has
the right to convey such software to Lessor. Lessor shall have the right, upon
reasonable prior notice to Lessee and during normal business hours, to inspect
the Equipment at its location.  Lessee shall not permit its rights or interest
hereunder to be subject to any lien, charge, or encumbrance.  Lessee shall not
permit the Equipment to become or remain a fixture to any real estate or an
accession to any personalty not leased hereunder.  Lessee shall not be
responsible for any liens, charges, or encumbrances on the Equipment caused by
Lessor.

of all levies, liens and security interests, and shall give Lessor immediate
notice of any attachment or other judicial process affecting any item of
Equipment.  Lessee shall pay all charges and local, state, and Federal taxes
(and reimburse Lessor for any such payments made by Lessor) which may now or
hereafter be imposed upon the ownership, leasing, rental, sale, purchase,
possession or use of the Equipment, excluding, however, all taxes on or
measured by Lessor's net income.  Further, Lessor may in its sole discretion
require to make payments in amounts and at intervals satisfactory to Lessor to
be held by Lessor in a non-interest bearing tax reserve account as security for
Lessee's faithful performance of its obligations herein.  The obligations of
Lessee to pay such sums shall be in addition to all other obligations of under
this Lease and shall continue in full force and effect notwithstanding the
termination of this Lease whether by expiration of time, by operation of law,
or otherwise.

         8.      INSURANCE.  Lessee will at its own expense maintain physical

Equipment in the name of Lessor and in such form as is commonly maintained on
comparable Equipment by companies similarly situated.  In all events Lessee
will cause to be carried and maintained in the names of Lessor and insurance
against all risks of physical damage to the Equipment as provided under a
standard all-risk policy in an amount from time to time not less than the
amount payable by Lessee under Section 9 hereof as the result of an Event of
Loss to the Equipment.  Lessee shall be liable for any loss not covered by
insurance.  AU said insurance shall be in form and amount satisfactory to
Lessor and shall provide the losses, if any, shall be payable to Lessor.
Lessee shall pay the premiums therefore and deliver to Lessor the policies of
insurance or duplicates thereof or other evidence satisfactory to Lessor of
such insurance coverage.  Each insurer shall agree by endorsement upon the
policy or policies issued by it or by independent instrument furnished to
Lessor that it will give Lessor thirty (30) days prior written notice of the
effective date of any alteration or cancellation of such policy.  Lessee hereby
irrevocably appoints Lessor as Lessee's attorney-in-fact to make claim for,
receive payment of, and execute and endorse all documents, check or drafts
received in payment for loss or damage under any said insurance policy.  In
case of the failure of to procure or maintain said insurance, Lessor shall have
the right, but shall not be obligated, to effect such insurance or compliance
on behalf of Lessee.  In that event, all moneys spent by and expenses of Lessor
in effecting such insurance or compliance shall be deemed to be additional
rent, and shall become due and owed forthwith with interest at 18% per annum or
such other maximum lawful contract rate as is otherwise allowed by law if less
than 18% and Lessee will pay the same with the periodic payment of rent next
due after receipt of notice from Lessor.

in a manner satisfactory to the Lessor, or (b) the unpaid balance of rentals
for the Term of Lease allocable to such Equipment (discounted to present value
at the New York Federal Reserve Bank Discount Rate less two percent, in effect
at the date of payment to Lessor for such Event of Loss) or according to the
attached casualty or amortization schedule, if applicable, plus any residual
value of such Equipment established by the Lessor and any other charges due

and/or able to use the expected tax deductions, credits or other benefits based
on the maximum Federal Income Tax Rate applicable to Lessor, in effect during
the term of the Lease.  The obligation to pay such sums to Lessor shall be in

                  comparable federal, state or local tax returns shall be issued
                  by Ameritech with respect to the arrangements contemplated by

                  common control with Consultant. "Affiliate" also means any

         c)       With respect to an entity other than Ameritech or Consultant,
                  an "Affiliate" shall mean any entity that directly or

8.       CONFIDENTIAL INFORMATION.

         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
                  has access from Ameritech through its performance hereunder
                  shall be considered confidential and shall be subject to the
                  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;

iii)    Consultant shall advise those employees who access the Information of

<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
        confidentiality notices are reproduced in full on such copies; and

v)      Unless the parties agree otherwise in writing, Consultant shall return
        all copies of such Information to Ameritech at Ameritech's request.



        b)      Consultant recognizes and agrees that the unauthorized use or
                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
                Information. The obligations herein contained shall expressly
                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;



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



iv)     is independently developed by Consultant without the use of Ameritech's 
        Information;

<PAGE>   6


v)       is APPROVED FOR RELEASE BY written authorization OF Ameritech, BUT ONLY
         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.

the prior written consent of Ameritech.



12.     SUBCONTRACTING.

Consultant shall not, without the prior written consent of Ameritech,

               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
               its obligations under this Agreement; provided, however, that the
               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,
               liabilities, obligations, suits, judgments, damages, expenses or
               costs (including reasonable attorneys' fees) (collectively,
               "Ameritech's Damages") which may be asserted against or incurred
               by Ameritech and which arise out of Consultant's performance or
               failure to perform its obligations under this Agreement;
               provided, however, that the foregoing indemnity shall not apply
               to Ameritech's Damages resulting from or relating to Ameritech's
               negligence or misconduct.

                  indirectly through that entity itself or one of its Affiliates
                  provides two-way cellular voice communication services or
                  other wireless communication or data services. Upon such
