                                    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

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, if the Company is profitable, that its levels of
profitability will not vary significantly between quarters.
    
 
   
     The Company experienced a net loss of approximately $625,000 in 1997 as a
result of losses from discontinued operations of approximately $876,000 and
losses on the disposal of such operations of approximately $2.0 million. The
Company's operating results may fluctuate as a result of many factors, including
the length of the sales cycle for new or existing customers, the size, timing or
duration of significant customer contracts, fluctuations in the number of
subscriber records under management, timing of new service offerings, demand by
license customers for new development services, customer acceptance of service
offerings, ability of the Company to hire, train and retain qualified personnel,
increased competition, changes in operating expenses, changes in the Company's
strategy, the financial performance of the Company's customers, changes in
telecommunications legislation and regulations that may affect the competitive
environment for the Company's services, and general economic factors. The
Company's contracts for data management services generally include a
non-recurring initial fee, and therefore, the Company may recognize
significantly increased revenue for a short period of time upon commencing
services for a new customer.
    
 
     The Company's expense levels are based in significant part on its
expectations regarding future revenue. The Company's revenue is difficult to
forecast because the market for the Company's services is evolving rapidly and
the length of the Company's sales cycle, the size and timing of significant
customer contracts and license fees and the timing of recognition of
non-recurring initial fees vary substantially among customers. Accordingly, the
Company may be unable to adjust spending in a timely manner to compensate for
any unexpected shortfall in revenue. Any significant shortfall could therefore
have a material adverse effect on the Company's business, financial condition
and results of operations. In addition, the Company hired a significant number
of employees in 1996, 1997 and the first quarter of 1998, and expects to
continue hiring additional employees during the remainder of 1998. The Company
expects that this increase will affect the Company's operating margins for the
short term. There can be no assurance that the Company can continue to report
operating profits, and failure to do so could have a material adverse effect on
the Company's business, financial condition and results of operations.
 
   
     Based on all of the foregoing, the Company believes that future revenue,
expenses and operating results are likely to vary significantly from quarter to
quarter. As a result, quarter-to-quarter comparisons of operating results are
not necessarily meaningful or indicative of future performance. Furthermore, it
is possible that in some future quarter the Company's operating results will be
below the expectations of public market analysts or investors. In such event, or
in the event that adverse conditions prevail, or are perceived to prevail, with
respect to the Company's business or generally, the market price of the
Company's Common Stock would likely be materially adversely affected. See
"Selected Financial Data" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

<PAGE>   10
 
LENGTHY SALES CYCLE
 
     Potential customers of the Company typically commit significant resources
to the technical evaluation of the Company's services and products and the
Company typically spends substantial time, effort and money providing education
regarding the Company's 9-1-1 OSS solution. The evaluation process often results
in an extensive and lengthy sales cycle, typically ranging between six months
and two years, making it difficult for the Company to forecast the timing and
magnitude of sales contracts. Delays associated with customers' internal
approval and contracting procedures, procurement practices, and testing and
acceptance processes are common. For example, customers' budgetary constraints
and internal acceptance reviews may cause potential customers to delay or forego
a purchase. The delay or failure to complete one or more large contracts could
have a material adverse effect on the Company's business, financial condition
and results of operations and cause the Company's operating results to vary
significantly from quarter to quarter. See "-- Significant Fluctuations in
Quarterly Results of Operations" and "Business -- Sales and Marketing."
 
RELIANCE ON SIGNIFICANT CUSTOMERS
 
   
     The Company historically has depended on, and expects to continue to depend
on, large contracts from a limited number of significant customers. During the
year ended December 31, 1996, the Company recognized approximately 82% of its
total revenue from continuing operations from Ameritech and U.S. WEST, each of
which accounted for greater than 10% of the Company's revenue in such year.
During the year ended December 31, 1997, the Company recognized approximately
81% of its total revenue from continuing operations from Ameritech, BellSouth
Inc. and U.S. WEST, each of which accounted for greater than 10% of the
Company's revenue in such year. The Company believes that these customers will
continue to represent a substantial portion of the Company's total revenue in
the future. Certain of the Company's contracts with these customers allow them
to cancel their contracts with the Company in the event of changes in
regulatory, legal, labor or business conditions. The Company's contracts with
these customers expire between 2004 and 2005. The loss of any of these customers
would have a material adverse effect on the Company's business, financial
condition and results of operations. 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, which will allow PSAPs to call all
numbers in a given area and warn of imminent danger. The introduction of
products and services embodying new technologies and the emergence of new
industry and technology standards can render existing products and services
obsolete and unmarketable in short periods of time. The Company expects other
vendors regularly to introduce new products and services, as well as
enhancements to their existing products and services, that will compete with the
services and products offered by the Company. As a result, the life cycles of
the Company's services and products are difficult to estimate. The Company
believes that its future success will depend in large part on its ability to
maintain and enhance its current service and product offerings, to develop and
introduce regularly new services and products that will keep pace with
technological advances and satisfy evolving customer requirements, and to
achieve acceptable levels of sales of its new services and products through its
current customers that resell the Company's solutions to their subscribers.
However, there can be no assurance that the Company will not experience
difficulties that could delay or prevent the successful development,
introduction or marketing of such new services and products or that its new
services and products will adequately meet the requirements of the marketplace
and achieve market acceptance. Announcements of currently planned or other new
service and product offerings by the Company or its competitors may cause
customers to defer the purchase of existing Company services and products. The
Company's inability to develop on a timely basis new services or products, or
the failure of such new services or products to achieve market acceptance, could
have a material adverse effect on the Company's business, financial condition
and results of operations. The development of new, technologically advanced
products and services is a complex and uncertain process requiring high levels
of innovation, as well as the accurate anticipation of technological and market
trends. There can be no assurance that the Company will successfully develop,
introduce or manage the transition to new services and products. Furthermore,
services and products such as those offered by the Company may contain
undetected or unresolved errors when they are first introduced or as new
versions are released. There can be no assurance that, despite extensive testing
by the Company, errors will not be found in new services and products after
commencement of commercial availability, resulting in delay in or loss of market
acceptance and sales, diversion of development resources, injury to the
Company's reputation or increased service and warranty costs, any of which could
have a material adverse effect on the Company's business, financial condition
and results of operations. Significant delays in meeting deadlines for announced
service or product introductions or performance problems with such products or
upgrades could result in an undermining of customer confidence in the Company's
services and products, which would materially adversely affect its customer
relationships as well.
    
 
     In addition, the Company plans to introduce transaction-based services and
software products to industries different from those the Company has
traditionally supported. There can be no assurance that the Company will be
successful in developing and marketing these new services and products or that
its current or new services and products will adequately meet the demands of its
new markets. Because it is generally not possible to predict the time required
and costs involved in reaching certain research, development and engineering
objectives related to entering new markets, actual development costs could
exceed budgeted amounts and estimated development schedules could require
extensions. Furthermore, there can be no assurance that the Company will not
experience difficulties that could delay or prevent the successful development,
introduction and marketing of these services and products. If the Company is
unable to develop and introduce new services and products to these new markets
in a timely manner, or if a new release of a product or service to such new
markets does not achieve market acceptance, the Company's business, financial
condition and results of operations could be materially adversely affected.
 
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
 
                                        9
<PAGE>   12
 
affecting this market segment, such as government regulation, technological
obsolescence and the entry of new competition. The Company expects that this
market will continue to account for substantially all of its revenue in the near
future. As a result, the Company's future success will depend on its ability to
continue to sell its 9-1-1 OSS solution to ILECs, CLECs and wireless carriers,
maintain and increase its market share by providing other value-added services
to the market, and successfully adapt its technology and services to other
related markets. There can be no assurance that markets for the Company's
existing services and products will continue to expand or that the Company will
be successful in its efforts to penetrate new markets. See
"Business -- Strategy."
 
FIXED PRICE CONTRACTS AND OTHER PROJECT RISKS
 
     During 1997, approximately 75% of the Company's revenue was generated on a
fixed price per subscriber basis. The Company generally enters into contracts
with a ten-year term for wireline data management services and with a
two-to-five-year term for wireless data management services for which the
Company generally receives a fixed monthly fee based upon the number of
subscribers and upon the services selected by the customer. Therefore, the
Company's failure to estimate accurately the resources required for a fixed
price per subscriber contract could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Overview."
 
     The Company provides 9-1-1 OSS services that are critical to the public's
perception of its customers. The Company's failure to meet a customer's
expectations in the performance of its services could damage the Company's
reputation and adversely affect its ability to attract new business, and may
have a material adverse effect upon its business, financial condition and
results of operations. The Company has undertaken, and in the future may
undertake, projects in which the Company guarantees performance based upon
defined operating specifications. Unsatisfactory performance may result in
client dissatisfaction and a reduction in payment to, or payment of damages by,
SCC, any of which could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     Because the Company's services and products are utilized by its customers
to provide critical 9-1-1 services, the provision of services and licensing of
software by the Company may entail the risk of product liability and related
claims. The Company's agreements with its customers typically require the
Company to indemnify its customers for the Company's own acts of negligence. The
Company currently has product liability insurance that, subject to liability
limitations and customary exclusions, covers claims resulting from the failure
of the Company's services or products to perform the function or serve the
purpose intended. To the extent that any claims are not covered by such
insurance, the Company's business, financial condition and results of operations
may be materially and adversely affected by a successful product liability
claim.
 
EMERGING TELECOMMUNICATIONS MARKET AND NEW CARRIERS; REGULATORY UNCERTAINTY
 
   
     The Company provides its 9-1-1 OSS solution to telecommunications carriers
in the wireline and wireless markets. Although these markets have experienced
significant growth and have been characterized by increased deregulation and
competition in recent years, there can be no assurance that such trends will
continue at similar rates or that the Company will be able to market and sell
effectively its products and services in such markets. In addition, many of the
new entrants in the telecommunications market are companies that lack
significant financial and other resources. To cultivate relationships with such
new market entrants, the Company may be required to offer alternative pricing
arrangements, which may provide for deferred payments. However, there can be no
assurance that the Company will be able to develop such relationships or that
new carriers that become customers of the Company will gain market acceptance
for their telecommunications services. If the Company permits customers that do
not have adequate financial resources to pay the Company for its services on a
deferred basis, the Company ultimately may be unable to collect payments for
such services. Because the Company historically has depended on a limited number
of long-term customer relationships, the failure of the Company to develop
relationships with, make sales to, or collect payments from new
telecommunications carriers, or the failure of the Company's customers to
compete effectively in the telecommunications market, could have a material
adverse effect on the Company's business,
    
 
                                       10

financial condition and results of operations. In addition, the
telecommunications industry is experiencing substantial consolidations and
changes that are unpredictable, and any such consolidation or change could have
a material adverse effect on the Company's business, financial condition and
results of operations.
 
     9-1-1 services generally are funded by a locally imposed fee per subscriber
per month. A portion of this tax is paid to the local carrier providing the
9-1-1 services. The Company generally receives a monthly fee per subscriber from
its customers for management of 9-1-1 data records, allowing the carrier to
match its fixed revenue stream for 9-1-1 services with a fixed cost for record
management. Changes by local governments in the funding mechanism for 9-1-1
services or the parties responsible for the provision of such services could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
     The market for the Company's services and products has been influenced by
the adoption of regulations under the Telecommunications Act of 1996 (the "1996
Act"), the new duties imposed on ILECs by the 1996 Act to open the local
telephone markets to competition, and the new requirements imposed on wireless
carriers by the Order. Therefore, any changes to such legal requirements, the
adoption of new regulations by federal or state regulatory authorities under the
1996 Act or any legal challenges to the 1996 Act could have a material adverse
effect upon the market for the Company's services and products. Although the
1996 Act was designed to expand competition in the telecommunications industry,
the realization of the objectives of the 1996 Act is subject to many
uncertainties, including judicial and administrative proceedings designed to
define rights and obligations pursuant to the 1996 Act, actions or inactions by
ILECs and other carriers that affect the pace at which changes contemplated by
the 1996 Act occur, resolution of questions concerning which parties will
finance such changes, and other regulatory, economic and political factors.
 
     The Company is aware of certain litigation challenging the validity of the
1996 Act and the local telephone competition rules adopted by the FCC to
implement the 1996 Act. The U.S. Eighth Circuit Court of Appeals has invalidated
the pricing methodology and unbundling requirements adopted by the FCC while
upholding a portion of the FCC's local competition rules, and both the U.S.
federal government and ILECs have filed petitions for review with the U.S.
Supreme Court. In a recent decision, a U.S. District Court in Texas declared
unconstitutional the provisions of the 1996 Act requiring the Regional Bell
Operating Companies (the "RBOCs") to comply with certain conditions, including
local number portability ("LNP"), in order to receive regulatory approval to
enter long distance markets. The U.S. Department of Justice, representing the
FCC, has appealed this decision. Such litigation may serve to delay
implementation of the 1996 Act, which could adversely affect demand for the
Company's services and products. Any delays in the deadlines imposed by the 1996
Act, the FCC or the Order, or any invalidation, repeal or modification in the
requirements imposed by the 1996 Act, the FCC or the Order, could have a
material adverse effect on the Company's business, financial condition and
results of operations. Moreover, customers may require, or the Company otherwise
may deem it necessary or advisable, that the Company modify its services and
products to address actual or anticipated changes in the regulatory environment.
Any other delays in implementation of the 1996 Act, or other regulatory changes,
could materially adversely affect the Company's business, financial condition
and results of operations.
 
RISK OF SYSTEM FAILURES
 
     The Company's operations are dependent upon its ability to maintain its
computer and telecommunications equipment and systems in effective working
order, and to protect its systems against damage from fire, natural disaster,
power loss, telecommunications failure or similar events. Although all of the
Company's mission-critical systems and equipment are designed with built-in
redundancy and security, there can be no assurance that a fire, natural
disaster, power loss, telecommunications failure or similar event would not
result in an interruption of the Company's services. Any damage, failure or
delay that causes interruptions in the Company's operations could have a
material adverse effect on the Company's business, financial condition and
results of operations. Furthermore, any future addition or expansion of the
Company's facilities to increase 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
 
                                       11
<PAGE>   14
 
of a system failure or that such insurance will continue to be available to the
Company at all or, if available, that it will be available on commercially
reasonable terms. See "Business -- Products and Services."
 
MANAGEMENT OF CHANGE
 
     The Company has expanded its operations rapidly over the past several
years, placing significant demands on its administrative, operational and
financial personnel and systems. Additional expansion by the Company may further
strain its management, operational, financial reporting, and other systems and
resources. There can be no assurance that the Company's systems, resources,
procedures, controls and existing space will be adequate to support such
expansion of the Company's operations. The Company's future operating results
will depend substantially on the ability of its officers and key employees to
manage changing business conditions and to implement and improve its management,
operational, financial control and other reporting systems. In addition, the
Company's future operating results depend on its ability to attract, train and
retain qualified consulting, technical, sales, financial, marketing and
management personnel. Failure to hire, train or retain qualified personnel
necessary to keep pace with the Company's development of products and services
could have a material adverse effect on the Company's business, financial
condition and results of operations. Continued expansion will require the
Company's management to: enhance management information and reporting systems;
standardize implementation methodologies of SCC's NDSC; further develop its
infrastructure; and continue to maintain customer satisfaction. If the Company
is unable to respond to and manage changing business conditions, the quality of
the Company's products and services, its ability to retain key personnel and its
business, financial condition and results of operation could be materially
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Management."
 
HIGHLY COMPETITIVE MARKET; COMPETITION
 
     The market for 9-1-1 OSS solutions is intensely competitive and the Company
expects competition to increase in the future. The Company believes that the
principal competitive factors affecting the market for 9-1-1 OSS services
include flexibility, reliability, manageability, technical features, wireless
support, performance, ease of use, price, scope of product offerings, and
customer service and support. Although the Company believes that its solution
competes favorably with respect to such factors, there can be no assurance that
the Company can maintain its competitive position against current and potential
competitors, especially those with significantly greater financial, marketing,
support service, technical and other competitive resources.
 
     The Company's principal competitors generally fall within one of three
categories: internal development departments of major carriers or consulting
firms that support such departments; relatively smaller companies that offer
applications with limited scope; and larger companies that are either in the
process of entering the Company's market or have the potential to develop
products and services that compete with the Company's service offerings.
 
     A number of companies currently market or have under development software
products and services to provide 9-1-1 administration. The Company competes with
a few smaller companies, including XYPoint Corporation, for the provision of
9-1-1 data management services to wireless carriers, although the Company
expects more significant competition in the future. Mergers or consolidations
among these competitors or acquisitions of these companies by larger competitors
would make them more formidable competitors to the Company. There can be no
assurance that the Company's current and potential competitors will not develop
products and services that may be more effective than the Company's current or
future 9-1-1 solutions or that the Company's technologies and offerings will not
be rendered obsolete by such developments.
 
     Finally, there are a number of companies that market and sell various
products and services to telecommunications carriers, such as billing software
and advanced telecommunications equipment, that have been broadly adopted by the
Company's customers and potential customers. In addition, vendors of
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
 
                                       12
<PAGE>   15
 
render the Company's services obsolete and unmarketable, particularly if the
quality of such functionality were comparable to that of the Company's services.
Furthermore, even if the 9-1-1 functionality provided as standard features by
telecommunications software or networking hardware is more limited than that of
the Company's services, there can be no assurance that a significant number of
customers would not elect to accept more limited functionality in lieu of
purchasing additional products or services. For example, Lucent Technologies
offers carriers software systems with functionality similar to the Company's
services. Many of these larger companies have longer operating histories,
greater name recognition, access to larger customer bases and significantly
greater financial, technical and marketing resources than the Company. As a
result, they may be able to adapt more quickly to new or emerging technologies
and changes in customer requirements, or to devote greater resources to the
promotion and sale of their products and services, than the Company. If these
companies were to introduce products or services that effectively compete with
the Company's service offerings, they could be in a position to substantially
lower the price of their 9-1-1 products and services or to bundle such products
and services with their other product and service offerings.
 
     For the foregoing reasons, there can be no assurance that the Company will
be able to compete successfully against its current and future competitors.
Increased competition may result in price reductions, reduced gross margins and
loss of market share, any of which could materially and adversely affect the
Company's business, financial condition and results of operations. See
"Business -- Competition."
 
DEPENDENCE ON KEY PERSONNEL
 
   
     The Company's future success depends in large part on the continued service
of its key management, sales, product development and operational personnel,
including George Heinrichs, President and Chief Executive Officer, John Sims,
Chief Operating Officer, and Nancy Hamilton, Chief Financial Officer, and on the
Company's ability to continue to attract, motivate and retain highly qualified
employees, including technical, managerial and sales and marketing personnel.
Additionally, the Company expects to continue to expand the number of employees
engaged in sales, marketing and product development. However, competition in the
recruitment of highly qualified personnel in the software and telecommunications
services industry is intense and has become particularly significant in the
Denver metropolitan area. The inability to hire and retain qualified personnel
or the loss of the services of key personnel could have a material adverse
effect upon the Company's current business, development efforts and future
business prospects. If such personnel do not remain active in the Company's
business, the Company's operations could be materially adversely affected. The
Company currently maintains a key person life insurance policy only with respect
to Mr. Heinrichs. The Company is the named beneficiary of this $1,000,000
policy. See "Business -- Employees" and "Management."
    
 
DEPENDENCE ON PROPRIETARY RIGHTS
 
     The Company's success and its ability to compete depends significantly upon
its proprietary rights. The Company relies primarily on a combination of
copyright, trademark and trade secret laws, as well as confidentiality
procedures and contractual restrictions to establish and protect its proprietary
rights. There can be no assurance that such measures will be adequate to protect
the Company's proprietary rights. Further, the Company may be subject to
additional risks as it enters into transactions in foreign countries where
intellectual property laws are not well developed or are difficult to enforce.
Legal protections of the Company's proprietary rights may be ineffective in such
countries. Litigation to defend and enforce the Company's intellectual property
rights could result in substantial costs and diversion of resources, and could
have a material adverse effect on the Company's business, financial condition
and results of operations, regardless of the final outcome of such litigation.
Despite the Company's efforts to safeguard and maintain its proprietary rights,
there can be no assurance that the Company will be successful in doing so or
that the steps taken by the Company in this regard will be adequate to deter
misappropriation or independent third-party development of the Company's
technology, or to prevent an unauthorized third party from copying or otherwise
obtaining and using the 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.
 
                                       13
<PAGE>   16
 
     As the number of entrants to the Company's markets increases and the
functionality of the Company's services and products increases and overlaps with
the products and services of other companies, the Company may become subject to
claims of infringement or misappropriation of the intellectual property rights
of others. In certain of its customer agreements, the Company agrees to
indemnify its customers for any expenses or liabilities resulting from claimed
infringements of patents, trademarks or copyrights of third parties. In certain
limited instances, the amount of such indemnities may be greater than the
revenue the Company may have received from the customer. There can be no
assurance that third parties will not assert infringement or misappropriation
claims against the Company in the future with respect to current or future
product or service offerings. Any claims or litigation, with or without merit,
could be time consuming, result in costly litigation or require the Company to
enter into royalty or licensing arrangements. Such royalty or licensing
arrangements, if required, may not be available on terms acceptable to the
Company, if at all, and could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
RISKS ASSOCIATED WITH INTERNATIONAL SALES
 
     Although substantially all of the Company's revenue is generated from sales
to customers in the United States, the Company has generated revenue in Canada
and intends to enter additional international markets, which will require
significant management attention and financial resources. International sales
are subject to a variety of risks, including difficulties in establishing and
managing international distribution channels, and in translating products and
related materials into foreign languages. International operations are also
subject to difficulties in collecting accounts receivable, staffing, managing
personnel and enforcing intellectual property rights. Other factors that can
adversely affect international operations include fluctuations in the value of
foreign currencies and currency exchange rates, changes in import/export duties
and quotas, introduction of tariff or non-tariff barriers and economic or
political changes in international markets. There can be no assurance that these
factors will not have a material adverse effect on the Company's future
international sales and, consequently, on the Company's business, financial
condition and results of operations. Furthermore, any inability to obtain
foreign regulatory approvals on a timely basis could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Overview" and "Business -- Strategy."
 
RISKS RELATING TO POTENTIAL ACQUISITIONS
 
   
     As part of its overall strategy, the Company regularly evaluates
opportunities to enter into strategic acquisitions, including potential business
combinations and significant investments in complementary companies, assets,
products and technologies, although the Company has no present arrangements,
commitments or agreements with respect to any acquisition. Acquisitions involve
a number of operating risks that could materially adversely affect the Company's
business, financial condition and results of operations, including the diversion
of management's attention to assimilate the operations, products and personnel
of the acquired companies, the amortization of acquired intangible assets, and
the potential loss of key employees of the acquired companies. Furthermore,
acquisitions may involve businesses in which the Company lacks experience.
Because management has limited experience in acquisitions and the Company has no
experience in integrating acquired companies or technologies into its
operations, there can be no assurance that the Company will be able to manage
one or more acquisitions successfully, or that the Company will be able to
integrate the operations, products or personnel gained through any such
acquisitions without a material adverse effect on the Company's business,
financial condition and results of operations. See "Use of Proceeds."
    
 
YEAR 2000 CAPABILITY
 
     Many currently installed computer and software products are coded to accept
only two digit entries in the date code field. These date code fields will need
to accept four digit entries to distinguish twenty-first century dates from
twentieth century dates. As a result, in less than two years, computer systems
and/or software used 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
 
                                       14
<PAGE>   17
 
patch their current software systems for Year 2000 compliance. These
expenditures may result in reduced funds available to purchase services such as
those offered by the Company. Additionally, Year 2000 issues could cause a
significant number of companies, including current customers of the Company, to
re-evaluate their current system needs, and as a result, consider switching to
other systems or suppliers. This could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
   
     Certain of the Company's current contracts with its customers require that
the Company warrant Year 2000 capability by a certain date. Any failure to
achieve Year 2000 compliance by such date could have a material adverse effect
on the Company's business, financial condition and results of operations.
Although the Company is designing its services and products to be Year 2000
capable and tests third-party software that is incorporated with the Company's
services and products, there can be no assurance that the Company's services and
products, particularly when such products and services incorporate third-party
software, will contain all necessary date code changes in time. The Company
expects to incur approximately $125,000 in costs in 1998 in making its services
and products Year 2000 compliant. Any additional unanticipated expenses could
have a material adverse effect on the Company's business, financial condition
and results of operations.
    
 
     The Company utilizes off-the-shelf and custom software developed internally
and by third parties. To the extent that such software and systems do not comply
with Year 2000 requirements, there can be no assurance that potential systems
interruptions or the cost necessary to update such software will not have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
   
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
    
 
   
     Prior to this offering there has been no public market for the Company's
Common Stock, and there can be no assurance that an active public market for the
Company's Common Stock will develop or be sustained after the offering. The
initial offering price will be determined by negotiation among the Company and
the Underwriters based upon several factors. See "Underwriting" for a discussion
of the method of determining the initial public offering price. The trading
price of the Company's Common Stock could be subject to wide fluctuations in
response to variations in operating results, announcements of technological
innovations or new products by the Company or its competitors, changes in
financial estimates by securities analysts, and other events or factors. In
addition, the stock market has experienced volatility that has particularly
affected the market prices of equity securities of many high technology
companies and that often has been unrelated to the operating performance of such
companies. These broad market fluctuations may materially adversely affect the
market price of the Company's Common Stock.
    
 
   
IMMEDIATE AND SUBSTANTIAL DILUTION
    
 
   
     The purchasers of Common Stock in this offering will experience immediate
and substantial dilution in the net tangible book value per share of their
Common Stock. At an assumed initial public offering price of $14.00 per share
and after deducting estimated offering expenses payable by the Company and
estimated underwriting discounts and commissions, investors in this offering
will incur dilution of $11.28 per share. See "Dilution."
    
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
     Sales of a substantial number of shares of Common Stock in the public
market following this offering could adversely affect the market price for the
Company's Common Stock. The number of shares of Common Stock available for sale
in the public market is limited by restrictions under the Securities Act of
1933, as amended (the "Securities Act"), and lock-up agreements under which the
holders of such shares have agreed not to sell or otherwise dispose of any of
their shares for a period of 180 days after the date of this Prospectus without
the prior written consent of the BancAmerica Robertson Stephens. However,
BancAmerica Robertson Stephens, in its sole discretion and at any time without
notice, may release all or any portion of the securities subject to lock-up
agreements. When determining whether or not to release shares from the lock-up
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
 
                                       15
<PAGE>   18
 
of Common Stock will be eligible for future sale: on the date of this
Prospectus, 3,361,469 shares (including the 3,300,000 shares offered hereby)
will be eligible for sale; an additional 6,774,435 shares will be eligible for
sale 180 days after the date of this Prospectus. In addition, the Company
intends to register on a registration statement on Form S-8, approximately 90
days following the effective date of this offering, a total of 1,901,055 shares
of Common Stock subject to outstanding options or reserved for issuance under
the 1998 Stock Incentive Plan. Upon expiration of the lock-up agreements
referred to above, holders of approximately 6,383,723 shares of Common Stock
will be entitled to certain registration rights with respect to such shares. If
such holders, by exercising their registration rights, cause a large number of
shares to be registered and sold in the public market, such sales could have a
material adverse effect on the market price for the Company's Common Stock. See
"Shares Eligible for Future Sale."
 
CONTROL BY EXISTING STOCKHOLDERS; EFFECTS OF CERTAIN ANTI-TAKEOVER PROVISIONS
 
     Following the completion of this offering, members of the Board of
Directors and the executive officers of the Company, together with members of
their families and entities that may be deemed affiliates of or related to such
persons or entities, will beneficially own approximately 52.7% of the
outstanding shares of Common Stock of the Company. Accordingly, these
stockholders will be able to elect all members of the Company's Board of
Directors and determine the outcome of corporate actions requiring stockholder
approval, such as mergers and acquisitions. This level of ownership by such
persons and entities may have a significant effect in delaying, deferring or
preventing a change in control of the Company and may adversely affect the
voting and other rights of other holders of Common Stock. Certain provisions of
the Company's Amended and Restated Certificate of Incorporation, Amended and
Restated Bylaws, Delaware law and equity incentive plans also may discourage
certain transactions involving a change in control of the Company. This level of
ownership by such persons and entities, when combined with the ability of the
Board of Directors to issue "blank check" preferred stock without further
stockholder approval, may have the effect of delaying, deferring or preventing a
change in control of the Company. See "Management -- Directors and Executive
Officers," "Certain Transactions," "Principal and Selling Stockholders" and
"Description of Capital Stock."
 
MANAGEMENT'S DISCRETION OVER PROCEEDS OF THE OFFERING
 
     The primary purposes of this offering are to create a public market for the
Common Stock, to facilitate future access by the Company to public equity
markets and to obtain additional equity capital. As of the date of this
Prospectus, the Company has no specific plans as to the use of the net proceeds
from this offering, other than to pay $4,610,000 of outstanding bank
indebtedness and a related prepayment premium; accordingly, the Company's
management will have broad discretion as to the application of such net
proceeds. Pending any such uses, the Company plans to invest the net proceeds in
short-term, investment grade, interest-bearing securities. See "Use of
Proceeds."
 
NO DIVIDENDS
 
     The Company has not paid any cash or other dividends on its Common Stock,
nor does it expect to pay dividends in the foreseeable future. See "Dividend
Policy."
 
   
BENEFITS OF THE OFFERING TO CURRENT STOCKHOLDERS
    
 
   
     The completion of the offering made by this Prospectus will provide
significant benefits to the current stockholders of the Company, including
certain of its Directors and officers. The net proceeds to the Selling
Stockholders from the sale of the 1,200,000 shares of Common Stock offered by
them hereby, assuming an initial public offering price of $14.00 and after
deducting estimated underwriting discounts and commissions, are estimated to be
approximately $15.6 million. The Company will not receive any of the proceeds
from the sale of shares by the Selling Stockholders. The completion of this
offering will also create a public market for the Common Stock and thereby is
expected to increase the market value of the investment by current stockholders
in the Company. Upon the closing of this offering at the assumed initial public
offering price of $14.00, the difference between the aggregate purchase price
paid or payable by the Company's named executive officers for shares of Common
Stock held by them or subject to options held by them and the aggregate market
value of such shares will be approximately $11.1 million. See "Dilution."
    
 
                                       16
<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 $4.6 million of the proceeds to pay outstanding
bank indebtedness and a related prepayment premium. Of this amount, $4.0 million
will be used to prepay outstanding indebtedness and to pay a prepayment premium
of $160,000, pursuant to the Company's loan agreement with a bank. Such
indebtedness currently bears interest at the rate of 11% per annum and requires
principal payments of $250,000 beginning on March 31, 2001 and each subsequent
quarter end through December 31, 2002. Thereafter, principal payments of
$500,000 are due on March 31, 2003 and each subsequent quarter end, with the
final payment becoming due on November 30, 2003. Additionally, the Company
intends to use a portion of the proceeds to repay $450,000 outstanding under its
line of credit. Borrowings under the line of credit bear interest at prime rate
plus 1% (9.5% at April 30, 1998) and are due on April 15, 1999. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
    
 
   
     The Company expects to use its remaining net proceeds (estimated to be
approximately $21.9 million) for product development and general corporate
purposes, including working capital. A portion of the net proceeds also may be
used for the acquisition of businesses, products and technologies that are
complementary to those of the Company. While the Company regularly evaluates
opportunities to enter into strategic acquisitions, including potential business
combinations and investments in complementary companies, assets, products and
technologies, the Company has no present arrangements, commitments or agreements
with respect to any acquisition. Pending such uses, the Company intends to
invest the net proceeds from this offering in short-term, investment-grade,
interest-bearing securities.
    
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid dividends on its capital stock and
does not anticipate paying cash dividends within the foreseeable future. Certain
covenants contained in the Company's line of credit agreement and a loan
agreement restrict the payment of any dividends without the lender's prior
consent. Payments of future dividends, if any, will be at the discretion of the
Company's Board of Directors, subject to the restrictions discussed above, after
taking into account various factors, including the Company's financial
condition, operating results, cash needs and expansion plans. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

     The following table sets forth the capitalization of the Company as of
March 31, 1998: (i) on an actual basis; (ii) on a pro forma basis giving effect
to the conversion of all outstanding shares of Convertible Preferred Stock and
the exercise of an outstanding warrant to purchase shares of Common Stock, all

2,100,000 shares of Common Stock offered by the Company hereby at an assumed
initial public offering price of $14.00 and the application of the net proceeds
therefrom as described under "Use of Proceeds." This table should be read in
conjunction with the Financial Statements and Notes thereto appearing elsewhere
in this Prospectus.

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

                                    DILUTION
 
   
     The pro forma net tangible book value of the Company at March 31, 1998 was
approximately $1,854,000, or $0.22 per share. Pro forma net tangible book value
per share represents the total amount of the Company's tangible assets less
total liabilities, divided by the number of shares of Common Stock outstanding
after giving effect to the conversion of all outstanding Convertible Preferred
Stock and the exercise of an outstanding warrant. After giving effect to the
sale of 2,100,000 shares of Common Stock offered hereby by the Company at an
assumed initial public offering price of $14.00 per share and after deducting
estimated offering expenses payable by the Company and estimated underwriting
discounts and commissions, the Company's pro forma net tangible book value at
March 31, 1998, would have been $28,396,000, or $2.72 per share. This represents
an immediate dilution of $11.28 per share to new investors purchasing shares of
Common Stock in this offering. The following table illustrates this dilution:

(1) Sales by the Selling Stockholders in this offering will reduce the number of
    shares held by the existing stockholders to 7,142,007 or approximately 68.4%
    of the total number of shares of Common Stock outstanding after this
    offering, and will increase the number of shares to be purchased by new
    investors to 3,300,000 or approximately 31.6% of the total number of shares
    of Common Stock outstanding after the offering. See "Principal and Selling
    Stockholders."
    
 
   
     The foregoing tables assume no exercise of outstanding options. As of March
31, 1998, there were outstanding stock options to purchase an aggregate of
1,116,126 additional shares of Common Stock at a weighted average exercise price
of $3.13 per share. To the extent that these options are exercised, there will
be further dilution to new investors. See "Management -- Benefit Plans -- 1998
Stock Incentive Plan" and Note 5 of Notes to Financial Statements.

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

  Revenue
    
 
   
     Total Revenue. Total revenue increased 54%, from $5.1 million in the first
quarter of 1997 to $7.9 million in the first quarter of 1998.
    
 
   
     Data Management Services Revenue. Revenues from data management services
increased 55%, from $4.9 million in the first quarter of 1997 to $7.5 million in
the first quarter of 1998, representing approximately 95% of total revenue in
both periods. The increase resulted primarily from (i) non-recurring and monthly
fees from wireless customers in the first quarter of 1998, as the Company did
not begin to earn revenue from wireless customers until the third quarter of
1997, (ii) increased monthly fees from wireline customers, as the Company had
not completed the transition of records for a major customer in the first
quarter of 1997, and (iii) non-recurring fees from enhanced services provided in
the first quarter of 1998.
    
 
   
     Licenses and Implementation Services. Revenue from licenses and
implementation services increased 36%, from $271,000 in the first quarter of
1997 to $369,000 in the first quarter of 1998, as the Company earned revenue in
1998 related to a contract that was not in place in the first quarter of 1997.

  Costs and Expenses
    
 
   
     Cost of Data Management Services. Cost of data management services consists
primarily of labor and costs of interconnection with customers' systems and the
Company's infrastructure. Cost of data management services increased 54%, from
$3.1 million in the first quarter of 1997 to $4.8 million in the first quarter
of 1998, representing 61% and 64% of total revenue and data management services
revenue, respectively, in both periods. The dollar increase was due to the
addition of personnel and expansion of facilities to accommodate growth in the
Company's wireless and wireline operations.
    
 
   
     Cost of Licenses and Implementation Services. Cost of licenses and
implementation services consists primarily of labor, license fees for third
party software and related expenses. Cost of licenses and implementation
services increased 56%, from $98,000 in the first quarter of 1997 to $153,000 in
the first quarter of 1998, representing 2% of total revenue in both periods and
36% and 42% of licenses and implementation services revenue in the first quarter
of 1997 and the first quarter of 1998, respectively. The increase in dollars and
as a percent of licenses and implementation services revenue was due to work
performed on a contract in the first quarter of 1998 which contained higher cost
elements, including third-party software, than contracts in process in the first
quarter of 1997.
    
 
   
     Sales and Marketing. Sales and marketing expenses consist primarily of
expenses related to salaries and commissions, travel, trade shows and sales
collateral. Sales and marketing expenses decreased 10%, from $933,000 in the
first quarter of 1997 to $843,000 in the first quarter of 1998, representing 18%
and 11% of total revenue in the first quarter of 1997 and the first quarter of
1998, respectively. The decrease was primarily due to decreased commissions and
bonuses in the first quarter of 1998 caused by a change in the structure of the
incentive plans and a bonus paid to an individual in the first quarter of 1997,
as well as the transfer of a vice president to a general and administrative
position. These decreases were offset by increased headcount and public
relations costs.
    
 
   
     General and Administrative. General and administrative expenses consist
primarily of expenses related to the Company's information systems, finance,
human resources, legal, executive and financial planning departments. General
and administrative expenses increased 136%, from $485,000 in the first quarter
of 1997 to $1.1 million in the first quarter of 1998, representing 10% and 15%
of total revenue in the first quarter of 1997 and the first quarter of 1998,
respectively. The dollar increase was due to (i) the reassignment of certain
continuing resources, infrastructure and related general and administrative
expenses applicable to continuing operations, (ii) addition of personnel and
computer equipment in the accounting, information systems and human resources
departments to support the Company's growth and (iii) increased executive
bonuses due to increased profitability in the first quarter of 1998.
    
 
   
     Other Expenses, Net. Net other expenses consist primarily of interest
expense from the Company's borrowings and leases for capital equipment, offset
by interest income earned on the Company's cash balances. Other expenses
increased 101%, from $150,000 in the first quarter of 1997 to $301,000 in the
first quarter of 1998, representing 3% and 4% of total revenue in the first
quarter of 1997 and the first quarter of 1998, respectively. The dollar increase
was primarily due to interest related to the 4.0 million loan from a bank that
was outstanding in the first quarter of 1998, which was partially offset by
decreased interest expense resulting from a lower balance outstanding on the
Company's line of credit in the first quarter of 1998.
    
 
   
     Provision for income taxes. The Company's income tax provision increased
from $24,000 in the first quarter of 1997 to $46,000 in the first quarter of
1998 due to increased income generated in states where the Company did not have
net operating loss carryforwards available to offset net income.
    
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
  Revenue
 
     Total Revenue. Total revenue increased 83%, from $14.8 million in 1996 to
$27.1 million in 1997.
 
     Data Management Services Revenue. Revenue from data management services
increased 82%, from $13.2 million in 1996 to $24.0 million in 1997, representing
approximately 89% of total revenue in both years. This increase resulted from an
increase in non-recurring and monthly fees from existing customers, increased
 
                                       24
<PAGE>   27
 
sales of new services to existing customers, and the realization of
non-recurring and monthly fees from both wireline and wireless customers.
 
     Licenses and Implementation Services Revenue. Revenue from licenses and
implementation services increased 87%, from $1.6 million in 1996 to $3.1 million
in 1997. The increase resulted from the addition of a new contract in 1997.
 
  Costs and Expenses
 
   
     Cost of Data Management Services. Cost of data management services
increased 92%, from $8.0 million in 1996 to $15.4 million in 1997, representing
54% and 57%, respectively, of total revenue and 61% and 64%, respectively, of
data management services revenue. The increase as a percentage of total revenue
and data management services revenue resulted from the addition of employees and
other resources in early 1997 in anticipation of wireless contracts, although
the Company did not begin recognizing revenue from such contracts until the
third quarter of 1997.
    
 
   
     Cost of Licenses and Implementation Services. Cost of licenses and
implementation services increased 115%, from $596,000 in 1996 to $1.3 million in
1997, representing 4% and 5%, respectively, of total revenue and 36% and 42%,
respectively, of licenses and implementation services revenue. The increase as a
percentage of associated revenue was due to the inclusion of higher cost
elements, including third-party software, in contracts performed in 1997.
    
 
   
     Sales and Marketing. Sales and marketing expenses increased 20%, from $3.2
million in 1996 to $3.9 million in 1997, representing 22% and 14%, respectively,
of total revenue. The increase in dollar amount was primarily due to increases
in salaries, recruiting, relocation and travel costs caused by an increase in
the sales force and increased marketing activities in 1997. The remaining
increase was due to the reassignment of marketing resources and related expenses
to the Company's continuing operations.
    
 
   
     General and Administrative. General and administrative expenses increased
111%, from $1.5 million in 1996 to $3.2 million in 1997, representing 10% and
12%, respectively, of total revenue. Approximately $1.0 million of the increase
is related to the reassignment of certain continuing resources, infrastructure
and related general and administrative expenses applicable to the Company's
continuing operations. The remaining dollar and percentage increases resulted
primarily from increased costs necessary to develop and maintain the internal
and customer support information systems, increased depreciation expense in
1997, increased executive bonuses paid and accrued in 1997, and expansion of the
Company's facilities to accommodate the Company's growth.
    
 
   
     Other Expenses, Net. Other expenses increased 67%, from $527,000 in 1996 to
$879,000 in 1997, representing 4% and 3% of total revenue in 1996 and 1997,
respectively. The increase in dollar amount resulted from an increase in
interest expense caused by an increase in capital leases, a higher average
balance outstanding on the Company's line of credit in 1997, and interest
expense related to a $4.0 million borrowing in November 1997. This increase was
partially offset by an increase in interest income recognized, as the Company's
average cash balance increased in 1997.
    
 
     Provision 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
 
                                       25
<PAGE>   28
 
increase in dollar amount resulted from increased revenue from non-recurring and
monthly fees in 1996 from both existing and new wireline customers.
 
   
     Licenses and Implementation Services Revenue. Revenue from licenses and
implementation services decreased 58%, from $3.9 million in 1995 to $1.6 million
in 1996, representing 52% and 11%, respectively, of total revenue. The decrease
resulted from the implementation of a large project in 1995 without a comparable
amount of new business in 1996.
    
 
  Costs and Expenses
 
     Cost of Data Management Services. Cost of data management services
increased 182%, from $2.8 million in 1995 to $8.0 million in 1996, representing
38% and 54%, respectively, of total revenue and 80% and 61%, respectively, of
data management services revenue. Cost of data management services was greater
as a percentage of the related revenue in 1995 because the Company was building
the infrastructure for its data management services business, including hiring
and training employees, building the network infrastructure, preparing
facilities and converting data to the Company's systems. Cost of data management
services was higher as a percentage of total revenue in 1996 due to the
increased percentage of data management services revenue.
 
     Cost of Licenses and Implementation Services. Cost of licenses and
implementation services decreased 43%, from $1.0 million in 1995 to $596,000 in
1996, representing 14% and 4%, respectively, of total revenue and 27% and 36%,
respectively, of licenses and implementation services revenue. The increase as a
percentage of associated revenue was due to the inclusion of higher cost
elements, including third-party software, on contracts in 1996.
 
   
     Sales and Marketing. Sales and marketing expenses increased 59%, from $2.0
million in 1995 to $3.2 million in 1996, representing 27% and 22%, respectively,
of total revenue. The increase in dollar amount was primarily due to increased
salary, travel and related facilities costs caused by an increase in the sales
force, increased sales commissions and bonuses due to increased revenue, and
increased costs for trade shows. The remaining increase was due to an increase
in certain marketing expenses from the growth of continuing operations of the
Company.
    
 
   
     General and Administrative. General and administrative expenses increased
85%, from $830,000 in 1995 to $1.5 million in 1996, representing 11% and 10%,
respectively, of total revenue. This increase in dollar amount was primarily due
to salaries, travel and other costs related to the hiring of management and
other personnel in anticipation of growth in 1996. The increase was partially
offset by decreased relocation, bad debt and consulting expenses.
    
 
     Other Expenses, Net. Net other expenses increased 43%, from $368,000 in
1995 to $527,000 in 1996, representing 5% and 4%, respectively, of total
revenue. The increase in dollar amount was due to an increase in interest
expense primarily related to additional capital leases for equipment required to
operate the Company's data management services business. This increase was
partially offset by a decrease in interest expense caused by the conversion to
equity and repayment of certain notes payable in 1996.
 
     Provision for Income Taxes. The income tax provision decreased 44%, from
$16,000 in 1995 to $9,000 in 1996. This decrease was primarily due to a foreign
income tax refund received in 1996, offset by additional income generated in
1996 in states in which the Company did not have net operating loss
carryforwards available to offset net income.

\LIQUIDITY AND CAPITAL RESOURCES
    
 
   
     Since its inception the Company has funded its operations through cash
provided by operations, supplemented by equity and debt financing and leases on
capital equipment. As of March 31, 1998, the Company had $1.2 million in cash
and cash equivalents and $2.9 million in net accounts receivable. In 1996, the
Company generated cash from financing activities through the issuance of shares
of Convertible Preferred Stock for $4.0 million. In addition, the Company
borrowed $4.0 million in 1997 from a bank. The loan bears interest at 11%
through May 31, 1999, and at 12% thereafter through maturity. Principal payments
of $250,000 are due beginning on March 31, 2001, and will be payable at each
subsequent quarter end through December 31, 2002. Principal payments of $500,000
are due on March 31, 2003 and at each subsequent quarter end, with the final
payment due November 30, 2003. The Company may prepay the loan after June 30,
1998; however, a prepayment premium will be due equal to 4% of the amount
outstanding if prepaid between June 30, 1998 and November 30, 1998, 3% if
prepaid between December 1, 1998 and November 30, 1999 and 2% if prepaid between
December 1, 1999 and November 30, 2000. The loan is secured by a first priority
security interest in substantially all of the Company's assets. As of the date
of this Prospectus, the Company was in compliance with all covenants related to
this debt. The Company intends to use a portion of the proceeds from this
offering to prepay the $4.0 million of borrowings and to pay a prepayment
premium of $160,000.
    
 
     The Company used cash in 1996 and 1997 of $2.4 million and $2.6 million,
respectively, for the purchase of capital assets, primarily for use in the
delivery of its data management services. The Company 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 April 30, 1998) and are due April 15, 1999. The Company intends
to renew this line of credit. The credit line is collateralized by certain
assets of the Company. As of March 31, 1998, $450,000 was outstanding on the
line of credit. During 1996 and 1997, the Company had net borrowings under its
bank notes and line of credit of $623,000 and $2.8 million, respectively. The
Company intends to use a portion of the proceeds from this offering to repay the
$450,000 outstanding under its line of credit.
    
 
   
     The Company is designing its services and products to be Year 2000 capable
and tests third-party software that is incorporated with the Company's services
and products. There can be no assurance, however, that the Company's services
and products, particularly when such services and products incorporate third-
party software, will contain all necessary date code changes in time. The
Company expects to incur approximately $125,000 in costs in 1998 in making its
services and products Year 2000 compliant. Any additional unanticipated expenses
could have an adverse effect on the Company's business, financial condition and
results of operations. See "Risk Factors -- Year 2000 Capability."
    
 
   
     The Company believes that the remaining net proceeds from this offering,
together with cash generated from operations, will be sufficient to fund its
anticipated working needs, capital expenditures and any potential future
acquisitions for the foreseeable future. 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 adopted SFAS 130 in

the first quarter of 1998, however, the Company did not have any transactions
which would require additional disclosure under SFAS 130.
    
 
     Also in June 1997, the FASB issued Statement of Financial Accounting
Standards No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise and
Related Information." This statement, effective for financial statements for
periods beginning after December 15, 1997, requires that a public business
enterprise report financial and descriptive information about its reportable
operating segments. Generally, financial information is required to be reported
on the basis that it is used internally for evaluation of segment performance
and deciding how to allocate resources to segments. The adoption of SFAS 131 is
not expected to have a material impact on the Company's financial statements.

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

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

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

ENHANCED SERVICES OF SCC NATIONAL DATA SERVICES CENTER
 
     The Company offers enhancements to its 9-1-1 OSS services that provide
additional features and functionality. These services are targeted to specific
markets and are sold directly by the Company or indirectly through the Company's
customers.
 
     9-1-1Net. 9-1-1Net, an online tool, creates an active communication channel
serving the NDSC, carriers and PSAPs. Through 9-1-1Net, users can view live
address routing rules, send address updates, review inbound call load, error
statistics and ALI discrepancy reports, and receive new product updates.
 
     Private Switch ALI. Private telephone switches, commonly known as PBX's,
create a challenge for E9-1-1 operations because information describing the
individual caller's phone station or extension within a PBX may not be available
to the network receiving the 9-1-1 call. In the case of large facilities such as
campuses, hotels and hospitals, emergency response personnel may not have
adequate information to quickly determine the location of the caller. Private
Switch ALI allows PBX system managers to create and transmit appropriate data
records that identify a caller's extension or location within a facility for the
9-1-1 OSS.
 
     9-1-1Connect. SCC provides wireless carriers with 9-1-1 OSS services that
are similar to those provided to wireline customers and that fully comply with
Phase I of the Order. Once a wireless carrier receives a request from a PSAP to
activate wireless 9-1-1 services, SCC's program managers develop a plan with the
wireless carrier to activate service, including development of ILEC network
interconnections for both data and voice that are specific to the local wireless
network configuration and interface requirements. The program managers develop
graphic coverage area maps that are superimposed on maps of current public
safety agency boundaries. Routing recommendations can then be made and
coordinated with the appropriate PSAP.
 
     Subscriber ALI. The Company is currently preparing to test Subscriber ALI,
which is designed to allow subscribers to supply personal information in their
9-1-1 records such as medical condition, disability and language of choice. When
a subscriber calls 9-1-1, data previously provided by the subscriber will be
displayed along with traditional 9-1-1 information to the PSAP. A subscriber
also can designate a third party to be notified in the event a 9-1-1 call is
initiated from the subscriber's telephone. For example, parents away from home
would be notified when a child or babysitter calls 9-1-1 from their telephone.
The Company currently anticipates that this service will be available by late
1998.
 
     Emergency Warning and Evacuation System. The Company is currently
developing its Emergency Warning and Evacuation System to initiate outbound
calls selectively in the event of potential disasters such as flash flooding,
hazardous materials incidents, industrial accidents and localized weather
events. The Emergency Warning and Evacuation System will utilize spatially
classified location information and up-to-date telephone subscriber data and
will be able to deliver voice or fax warnings to a geographically targeted
population. SCC intends to offer its Emergency Warning and Evacuation System by
late 1998.
 
LICENSE PRODUCTS
 
     The Company offers 9-1-1 OSS software to customers that elect to manage
their own 9-1-1 data records rather than outsourcing such operations to SCC. SCC
also provides custom software development services to customers with specific or
local requirements through its engineering department. The engineering
department develops, customizes and enhances the software using a structured
approach to perform requirements analysis, software development and quality
assurance.
 
COMMERCIAL SERVICES
 
     Many of the underlying elements used by the Company in managing large
volumes of dynamic subscriber information have commercial applications in other
industries. For instance, the Company has developed and is testing a dynamic
call routing system that will allow telecommunications carriers to support
real-time assignment of routing destinations for calls processed in public
telecommunications networks. Historically, calls have been routed pursuant to
preplanned and preprogrammed routing instructions. The Company's dynamic call
assignment will allow greater flexibility in call routing to respond to call
load or other complex non-network factors. The Company also intends to offer
improved address information to other operations
 
                                       36

areas of telecommunications carriers such as their billing, ordering and
provisioning departments. Carriers can increase efficiencies and improve
customer service by responding to service calls with more accurate subscriber
location information.
 
SERVICE AND PRODUCT PRICING
 
     Pricing for SCC's NDSC services usually includes a non-recurring initial
fee due upon execution of a contract with a customer. Thereafter, customers
generally pay a monthly fee based on the number of subscriber records maintained
by the NDSC and upon the services selected by the customer. The Company
typically enters into ten-year agreements for wireline base services and two to
five-year agreements for wireless base services. During the contract term, SCC
may offer customers enhanced services, which may be provided on a revenue
sharing basis. SCC also licenses software, hardware and professional services
necessary for the management of 9-1-1 services to its customers in exchange for
license and implementation services fees and maintenance fees.
 
SERVICE INFRASTRUCTURE AND ARCHITECTURE
 
     The Company's operations include central data administration and
distributed systems for real-time 9-1-1 transaction support. Based on large
scale, fault-tolerant Tandem computers, the Company's major processing systems
are configured to provide high reliability. They are also designed to provide
significant capacity for continued growth using the Tandem NSK scalable
message-based architecture.
 
     The Company's central data administration systems, located in Boulder,
Colorado, are a key element of its 9-1-1 OSS, and are used to perform routine
data maintenance and to support new customer transition and initial system
loads. SCC's NDSC also maintains a central monitoring facility in Boulder that
operates 24 hours a day, seven days a week. Data network access for the central
administration systems is provided using traditional T-1 connectivity to the
networks operated by SCC and its customers. To improve reliability and
survivability, the primary links are designed to have three or more backup paths
to access SCC's distributed networks, including VSAT satellite links. A
"hot-site" emergency business recovery facility has been established in New York
and can be activated to continue routine operations in the event of a disaster
at the Boulder site. Electronic processing necessary to handle actual 9-1-1
calls is geographically distributed and remains a local service for each region,
so SCC's central data administration systems are not in the actual 9-1-1 call
path.
 
     Distributed throughout the U.S., the Company's real-time 9-1-1 OSS servers
are located in shared, hardened computer facilities. The systems are deployed in
pairs or quads. System pairs are intentionally distributed to different
geographic locations to provide an additional level of reliability. These
systems provide data display for thousands of public safety agencies throughout
the service areas of SCC's customers. Direct interface to telephone control
switches is also supported on these platforms, providing the information
necessary to route calls to the jurisdictionally appropriate PSAP. The Company
also uses a number of Microsoft NT servers for internal administrative
processing and extranet support.
 
CUSTOMERS
 
   
     The Company provides its services to a range of telecommunications service
providers, including ILECs, CLECs and wireless carriers. The Company also
licenses its software and provides 9-1-1 data clearinghouse services directly
and indirectly to over 600 independent telephone companies. During the year
ended December 31, 1996, the Company recognized approximately 82% of total
revenue from continuing operations from Ameritech and U.S. WEST, each of which
accounted for greater than 10% of the Company's revenue in such periods. During
the year ended December 31, 1997, the Company recognized approximately 81% of
total revenue from Ameritech, BellSouth Inc. and U.S. WEST customers, each of
which accounted for greater than 10% of the Company's revenue in such period. 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 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

     Wireless Carriers. The Company's customers include 360 Communications
Company, AT&T Wireless Services, Sprint PCS, U.S. WEST Wireless and Vanguard
Cellular Systems.
    
 
     License Customers. The Company's license customers include Bell Atlantic,
Bell Canada, Pacific Bell and GTE Network Services.
 
SALES AND MARKETING
 
   
     The Company's marketing efforts are focused on targeting key carriers and
PSAPs in each geographical market through advertising in telecommunications
industry publications, participation in trade shows, presentations at technical
conferences and other initiatives. Additionally, SCC employees serve as the
chairpersons and members of key standards committees related to emergency
communications services. The Company's sales strategy relies on direct channels
of distribution for its services. The Company has dedicated account teams to
work with each existing and potential customer. The Company's account teams
develop relationships with 9-1-1 service providers through a consultative,
problem-solving sales process and work closely with customers and potential
customers to determine how their needs can be fulfilled by the Company's
services. As of April 30, 1998, the Company employed 18 persons in its sales and
marketing organization. Sales cycles range from six months to over two years.
See "Risk Factors -- Significant Fluctuations in Quarterly Results of
Operations" and "-- Lengthy Sales Cycle."
    
 
RESEARCH AND DEVELOPMENT
 
   
     The Company directs its research and development efforts toward providing
highly scalable applications that enable a more efficient 9-1-1 OSS process that
improves data quality. Development efforts currently in process are focused on
further embedding and using spatial coordinate data to manage geographic
assignment and other data, further enhancing the Company's wireless offerings.
These offerings include improving the Company's software, integrating standard
Web browser technology, and the development of decision support systems. By late
1998, the Company expects to introduce Subscriber ALI, which will allow
subscribers to append medical and other important data to their ALI record, and
Emergency Warning and Evacuation System, which will allow PSAPs to call all
numbers in a given area and warn of imminent danger. Research and development
expenses totaled approximately $338,000, $230,000 and $738,000 for December 31,
1995, 1996, and 1997, respectively. See "-- Products and Services -- Enhanced
Services of SCC National Data Services Center" and "Risk Factors -- Dependence
on New Products; Rapid Technological Change."
    
 
COMPETITION
 
     The market for 9-1-1 OSS solutions is intensely competitive and the Company
expects competition to increase in the future. The Company believes that the
principal competitive factors affecting the market for 9-1-1 OSS solutions
include effectiveness with existing infrastructure, reliability, manageability,
technical features, wireless support, performance, ease of use, price, scope of
product offerings, and customer service and support. Although the Company
believes that its solution competes favorably with respect to such factors,
there can be no assurance that the Company can maintain its competitive position
against current and potential competitors, especially those with significantly
greater financial, marketing, service support, technical and other competitive
resources.
 
     The Company's principal competitors generally fall within one of three
categories: internal development departments of major carriers or consulting
firms that support such departments; relatively smaller companies that offer
applications with limited scope; and larger companies that are either in the
process of entering the Company's market or have the potential to develop
products and services that compete with the Company's
 
                                       38
<PAGE>   41
 
   
service offerings. Potential customers sometimes rely on their own internal
development teams to formulate 9-1-1 OSS systems or to retain consultants to
undertake such a project. The Company believes that its 9-1-1 OSS solution
competes favorably with internally developed systems, which are expensive to
develop and maintain, may not provide a comprehensive, reliable approach to
9-1-1 OSS services, and may not provide the flexibility to adapt readily to
regulatory, technological and market changes.
    
 
     In addition, a number of companies currently market or have under
development software products and services to provide 9-1-1 administration. The
Company competes with a few smaller companies, including XYPoint Corporation,
for the provision of 9-1-1 OSS services to wireless carriers, although the
Company expects more significant competition to emerge in the future. The
Company believes that, to date, none of these relatively smaller companies offer
products or services that are as robust in features or as comprehensive in scope
as the Company's products and services. Although it is likely that the product
development efforts of these companies eventually will enable them to offer a
line of products or services to compete with the Company's current service
offerings, the Company intends to continue to dedicate significant resources for
product and service development in order to expand the Company's capabilities
ahead of these competitors. Notwithstanding, the Company expects additional
competition from these established competitors and from other emerging
companies. Mergers or consolidations among these competitors or acquisitions of
these companies by larger competitors would make them more formidable
competitors to the Company. There can be no assurance that the Company's current
and potential competitors will not develop products and services that may be
more effective than the Company's current or future 9-1-1 data management
solutions or that the Company's technologies and offerings will not be rendered
obsolete by such developments.
 
     Finally, there are a number of companies that currently market and sell
various products and services to telecommunications carriers, such as billing
software and advanced telecommunications equipment, that have been broadly
adopted by the Company's customers and potential customers. In addition, vendors
of telecommunications software and hardware in the future may enhance their
products to include functionality that is currently provided by the Company's
solutions. The widespread inclusion of the functionality of the Company's
service offerings as standard features of other telecommunications software or
hardware could render the Company's services obsolete and unmarketable,
particularly if the quality of such functionality were comparable to that of the
Company's services. Furthermore, even if the 9-1-1 functionality provided as
standard features by telecommunications software or networking hardware is more
limited than that of the Company's services, there can be no assurance that a
significant number of customers would not elect to accept more limited
functionality in lieu of purchasing additional products or services. For
example, Lucent Technologies offers carriers software systems with functionality
similar to the Company's services. Many of these larger companies have longer
operating histories, greater name recognition, accesses to larger customer bases
and significantly greater financial, technical and marketing resources than the
Company. As a result, they may be able to adapt more quickly to new or emerging
technologies and changes in customer requirements, or to devote greater
resources to the promotion and sale of their products and services, than the
Company. The Company believes that the entry of these larger companies into its
market will require them to undertake operations that are currently not within
their core areas of expertise, and thus expose them to significant uncertainties
in the product development process or in providing a range of products and
services to comprehensively address the 9-1-1 requirements which the Company's
services addresses. However, if these companies were to introduce products or
services that effectively compete with the Company's service offerings, they
could be in a position to substantially lower the price of their 9-1-1 products
and services or to bundle such products and services with their other product
and service offerings.
 
     For the foregoing reasons, there can be no assurance that the Company will
be able to compete successfully against its current and future competitors.
Increased competition may result in price reductions, reduced gross margins and
loss of market share, any of which would materially and adversely affect the
Company's business, financial condition and results of operations. See "Risk
Factors -- Highly Competitive Market; Competition."

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

(1) The options were granted to each of the Named Officers pursuant to the 1990
    Stock Option Plan. Each option vests 24% one year from the date of grant and
    2% each month thereafter.
 
(2) The five percent and ten percent assumed annual rates of compounded stock
    price appreciation are mandated by the rules of the Securities and Exchange
    Commission. There can be no assurance provided to the option holder or any
    other holder of the Company's securities that the actual stock price
    appreciation over the ten-year option term will be at the assumed five
    percent and ten percent levels or at any other defined level.

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

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

                          DESCRIPTION OF CAPITAL STOCK
 
     The Company is authorized to issue 30,000,000 shares of Common Stock, $.001
par value, and 15,000,000 shares of undesignated preferred stock, $.001 par
value (the "Preferred Stock").
 
COMMON STOCK
 
   
     As of April 30, 1998, there were 8,342,853 shares of Common Stock
outstanding held of record by 124 stockholders. As of April 30, 1998, options to
purchase an aggregate of 1,114,046 shares of Common Stock were also outstanding.
See "Management -- Stock Plans."
    
 
     The holders of Common Stock are entitled to one vote per share on all
matters to be voted on by shareholders and have cumulative voting rights with
respect to the election of directors. Subject to the prior rights of holders of
Preferred Stock, if any, the holders of Common Stock are entitled to receive
such dividends, if any, as may be declared from time to time by the Board of
Directors in its discretion from funds legally available therefor. Upon
liquidation or dissolution of the Company, the remainder of the assets of the
Company will be distributed ratably among the holders of Common Stock after
payment of liabilities and the liquidation preferences of any outstanding shares
of Preferred Stock. The Common Stock has no preemptive or other subscription
rights and there are no conversion rights or redemption or sinking fund
provisions with respect to such shares. All of the outstanding shares of Common
Stock are, and the shares to be sold in this offering will be, fully paid and
nonassessable.
 
PREFERRED STOCK
 
   
     The Company is authorized to issue 15,000,000 shares of undesignated
Preferred Stock. The Board of Directors has the authority to issue the Preferred
Stock in one or more series and to fix the price, rights, preferences,
privileges and restrictions thereof, including dividend rights, dividend rates,
conversion rights, voting rights, terms of redemption, redemption prices,
liquidation preferences and the number of shares constituting a series or the
designation of such series, without any further vote or action by the Company's
stockholders. The issuance of Preferred Stock, while providing desirable
flexibility in connection with possible acquisitions and other corporate
purposes, could have the effect of delaying, deferring or preventing a change in
control of the Company without further action by the stockholders and may
adversely affect the market price of, and the voting and other rights of, the
holders of Common Stock. The Company has no current plans to issue any shares of
Preferred Stock.
    
 
REGISTRATION RIGHTS
 
     Under the Registration Rights Agreement, the holders of approximately
6,188,575 shares of Common Stock and their permitted transferees (the "Holders")
are entitled to certain rights with respect to the registration of such shares
("Registrable Securities") under the Securities Act. Under the terms of the
Registration Rights Agreement, the holders of at least 50% of the Registrable
Securities may require, on two occasions after six months from the effective
date of this offering, that the Company use its best efforts to register the
Registrable Securities for public resale. In addition, if the Company proposes
to register any of its securities under the Securities Act, either for its own
account or for the account of other security holders exercising registration
rights, the Holders are entitled to notice of such registration and are entitled
to include shares of such Common Stock therein. The Holders may also require the
Company on an unlimited number of occasions to register all or a portion of
their Registrable Securities on Form S-3 under the Securities Act when use of
such form becomes available to the Company. All such registration rights are
subject to certain conditions and limitations, including the right of the
underwriters of an offering to limit the number of shares to be included in such
registration. In addition, the Company need not effect a registration within six
months following a previous registration, or after such time as all Holders may
sell under Rule 144(k) all shares of Common Stock to which such registration
rights apply. See "Certain Transactions."
 
     Additionally, the holder of a warrant to purchase 195,148 shares of Common
Stock is entitled to request registration of such shares pursuant to a separate
registration rights agreement. In addition, if the Company proposes to register
any of its securities under the Securities Act, either for its own account or
for the account
 
                                       51
<PAGE>   54
 
or for other security holders exercising registration rights, the warrant holder
is entitled to notice of such registration and is entitled to include shares of
such Common Stock therein. The warrant will be exercised in full upon the
closing of this offering.
 
POSSIBLE ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER PROVISIONS
 
   
  Amended and Restated Certificate of Incorporation and Restated Bylaws
    
 
   
     The Company's Amended and Restated Certificate of Incorporation authorizes
the Board to establish one or more series of undesignated Preferred Stock, the
terms of which can be determined by the Board at the time of issuance. See
"-- Preferred Stock." The Amended and Restated Certificate of Incorporation also
provides that all stockholder actions must be effected at a duly called meeting
of stockholders and not by a consent in writing. In addition, effective upon the
closing of this offering, the Company's Restated Bylaws will not permit
stockholders of the Company to call a special meeting of stockholders; only the
Company's Chief Executive Officer, President or Chairperson of the Board or a
majority of the Board will be permitted to call a special meeting of
stockholders. The Restated Bylaws also will require that stockholders give
advance notice to the Company's Secretary of any nominations for Director or
other business to be brought by stockholders at any stockholders' meeting and
require a vote of 66 2/3% of the stockholders or a majority of the members of
the Board to amend the Restated Bylaws. These provisions of the Amended and
Restated Certificate of Incorporation and the Restated Bylaws could discourage
potential acquisition proposals and could delay or prevent a change in control
of the Company. Such provisions also may have the effect of preventing changes
in the management of the Company.
    
 
  Delaware Anti-Takeover Statute
 
     The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203"), which, subject to certain exceptions, prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholder (defined as any person or entity that is the beneficial owner of at
least 15% of a corporation's voting stock) for a period of three years following
the time that such stockholder became an interested stockholder, unless: (i)
prior to such time, the board of directors of the corporation approved either
the business combination or the transaction that resulted in the stockholder's
becoming an interested stockholder; (ii) upon consummation of the transaction
that resulted in the stockholder's becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding, for purposes of
determining the number of shares outstanding, those shares owned (x) by persons
who are directors and also officers and (y) by employee stock plans in which
employee participants do not have the right to determine confidentially whether
shares held subject to the plan will be tendered in a tender or exchange offer;
or (iii) at or subsequent to such time, the business combination is approved by
the Board and authorized at an annual or special meeting of stockholders, and
not by written consent, by the affirmative vote of at least two-thirds of the
outstanding voting stock that is not owned by the interested stockholder.
 
     Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii) any
sale, lease, exchange, mortgage, transfer, pledge or other disposition involving
the interested stockholder and 10% or more of the assets of the corporation;
(iii) subject to certain exceptions, any transaction which results in the
issuance or transfer by the corporation of any stock of the corporation to the
interested stockholder; (iv) any transaction involving the corporation that has
the effect of increasing the proportionate share of the stock of any class or
series of the corporation beneficially owned by the interested stockholder; or
(v) the receipt by the interested stockholder of the benefit of any loans,
advances, guarantees, pledges or other financial benefits provided by or through
the corporation.

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
 
                                       53
<PAGE>   56
 
significant amounts of the Common Stock of the Company in the public market
could adversely affect the market price of the Common Stock and could impair the
Company's ability to raise capital through an offering of its equity securities.
 
     In addition, the Company intends to register approximately 90 days after
the 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 and such Selling
Stockholders will be obligated, pursuant to the option, to sell shares to the
extent the option is exercised. The Underwriters may exercise such option only
to cover over-allotments made in connection with the sale of shares of Common
Stock offered hereby.
    
 
     The Underwriting Agreement contains covenants of indemnity among the
Underwriters, the Company and the Selling Stockholders against certain civil
liabilities, including liabilities under the Securities Act and liabilities
arising from breaches of representations and warranties contained in the
Underwriting Agreement.
 
     Each officer and director and certain holders of shares of the Company's
Common Stock have agreed with the Representatives, for a period of 180 days
after the date of this Prospectus (the "Lock-Up Period"), subject to certain
exceptions, not to offer to sell, contract to sell, or otherwise sell, dispose
of, loan, pledge or grant any rights with respect to any shares of Common Stock,
any options or warrants to purchase any shares of Common Stock, or any
securities convertible into or exchangeable for shares of Common Stock owned as
of
 
                                       55

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

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

                         NOTES TO FINANCIAL STATEMENTS
   
              (INCLUDING INFORMATION RELATED TO UNAUDITED PERIODS)
    
(1) ORGANIZATION, BUSINESS AND LIQUIDITY
 
     SCC Communications Corp., doing business as SCC (the "Company"), is a
Delaware corporation. The Company is the leading provider of 9-1-1 operations
support systems services to incumbent local exchange carriers, competitive local
exchange carriers and wireless carriers in the United States. The Company
manages the data which enables 9-1-1 calls to be routed to the appropriate
public safety agency with accurate and timely information about the caller's
identification and location. In addition, the Company licenses its 9-1-1
software to carriers that wish to manage the delivery of 9-1-1 data management
services in-house.
 
LIQUIDITY
 
   
     Although the Company had a working capital deficit at December 31, 1997,
the Company generated net income from continuing operations before income taxes
of approximately $2,455,000 while also generating positive operating cash flows
of approximately $5,400,000 in 1997. The Company believes that its operating
cash and its line of credit, which has been renewed through April 15, 1999, will
be adequate to meet its cash requirements for operations for the next twelve
months.

     Assets and liabilities related to contracts are included in current assets
and liabilities in the accompanying balance sheets since they will be liquidated
in the normal course of contract completion, although this may require more than
one year.
 
PROPERTY AND EQUIPMENT
 
     Depreciation of property and equipment is computed using the straight-line
method over estimated useful lives of three to five years for computer hardware
and equipment, five years for furniture and fixtures and the life of the lease
for leasehold improvements. The costs of repairs and maintenance are expensed
while enhancements to existing assets are capitalized.
 
SOFTWARE DEVELOPMENT COSTS
 
     The Company expenses the costs of developing computer software until
technological feasibility is established and capitalizes all costs incurred from
that time until the software is available for general customer release.
Technological feasibility for the Company's computer software products is based
upon the earlier of the achievement of (a) a detail program design free of
high-risk development issues or (b) completion of a working model. Costs of
major enhancements to existing products with a wide market are capitalized while
routine maintenance of existing products is charged to expense as incurred. The
establishment of technological feasibility and the ongoing assessment of the
recoverability of capitalized computer software development costs requires
considerable judgment by management with respect to certain external factors,
including, but not limited to, technological feasibility, anticipated future
gross revenues, estimated economic life and changes in software and hardware
technology.
 
   
     Capitalized software costs are amortized on a product-by-product basis. The
annual amortization is the greater of the amount computed using (a) the ratio
that current gross revenues for a product bear to the total of current and
anticipated future gross revenues for that product, or (b) the straight-line
method over the remaining estimated economic life of the product which is
typically five years. Accumulated amortization of capitalized software costs
from continuing operations totaled $38,000, $97,000 and $201,000, respectively,
for the years ended December 31, 1995, 1996 and 1997, and is included in cost of
data management services and licenses and implementation services in the
statements of operations.

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

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
   
              (INCLUDING INFORMATION RELATED TO UNAUDITED PERIODS)
    
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions. These estimates affect the reported amounts of assets and
liabilities, disclosure of contingent assets and liabilities at the date of the
financial statements, and the reported amounts of revenue and expenses during
the reporting period. Actual results could differ from those estimates.
 
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 income (loss)
per share" includes the effects of potentially issuable common stock, but only
if dilutive (i.e., a loss per share is never reduced). The treasury stock
method, using the average price of the Company's common stock for the period, is
applied to determine dilution from options and warrants. The if-converted method
is used for convertible securities. Potentially dilutive common stock options
that were excluded from the calculation of diluted income per share

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

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

UNAUDITED PRO FORMA INFORMATION
 
     The Company is contemplating a public offering of its common stock. If such
an offering is consummated, all of the Convertible Preferred Stock (Note 4)
outstanding as of the closing date will be converted into shares of common
stock. In addition, the put option related to common stock warrants will expire
upon completion of the offering and the common stock warrants will be exercised
for $100 into shares of common stock. The pro forma stockholders' equity in the
balance sheet as of December 31, 1997 reflects the conversion of all outstanding
Convertible Preferred Stock and the exercise of the common stock warrant to
stockholders' equity (deficit). Had the conversion of the Convertible Preferred
Stock occurred on January 1, 1997, basic and diluted net income per share from
continuing operations would have been $0.28 and $0.26, respectively for the year
ended December 31, 1997.
 
   
INTERIM RESULTS (UNAUDITED)
    
 
   
     The accompanying balance sheet as of March 31, 1998, the statements of
operations and of cash flows for the three months ended March 31, 1997 and 1998,
and the statement of stockholders' equity (deficit) for the three months ended
March 31, 1998 are unaudited. In the opinion of management, the statements have
been prepared on the same basis as the audited financial statements and include
all adjustments, consisting only of normal recurring adjustments, necessary for
the fair statement of the results of the interim periods. Operating results for
the three months ended March 31, 1998 are not necessarily indicative of the
results that may be expected for the year ending December 31, 1998.
    
 
RECLASSIFICATIONS
 
     Certain reclassifications have been made to prior year balances to conform
to the current year presentation.
 
(3) DISCONTINUED OPERATIONS
 
     On June 30, 1997, the Company sold the net assets of its Premise Products
Division. The sale resulted in a net loss of $2,032,000. The net losses of this
division are included in the statements of operations as loss from operations of
discontinued division. Revenue from the division for the years ended December
31, 1995 and 1996 and the six months ended June 30, 1997, were $8,798,000,
$12,274,000 and $5,785,000, respectively.

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

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

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

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

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

     Management believes the tax benefits of $4,552,000 and $4,639,000 as of
December 31, 1996 and 1997, respectively, do not satisfy the realization
criteria set forth in SFAS No. 109 and has recorded a valuation allowance for

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

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

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

ITEM 17. UNDERTAKINGS.
 
     The undersigned hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to Directors, officers and controlling persons of the Company
pursuant to the provisions described in Item 14, or otherwise, the Company has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Company of expenses
incurred or paid by a Director, officer or controlling person of the Company in
the successful defense of any action, suit or proceeding) is asserted by such
Director, officer or controlling person in connection with the securities being
registered, the Company will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
     The undersigned registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this registration statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

      amendments to such registration statement, such amended prospectuses
      subject to completion and such abbreviated registration statements
      pursuant to Rule 462(b) of the Rules and Regulations as may have been
      required prior to the date hereof have been similarly prepared and filed
      with the Commission; and the Company will file such additional amendments
      to such registration statement, such amended prospectuses subject to
      completion and such abbreviated registration statements as may hereafter
      be required.  Copies of such registration statement and amendments, of
      each related prospectus subject to completion (the "Preliminary
      Prospectuses") and of any abbreviated registration statement pursuant to
      Rule 462(b) of the Rules and Regulations have been delivered to you.

                   If the registration statement relating to the Shares has
      been declared effective under the Act by the Commission, the Company will
      prepare and promptly file with the Commission the information omitted
      from the registration statement pursuant to Rule 430A(a) or, if
      BancAmerica Robertson Stephens, on behalf of the several Underwriters,
      shall agree to the utilization of Rule 434 of the Rules and Regulations,
      the information required to be included in any term sheet filed pursuant
      to Rule 434(b) or (c), as applicable, of the Rules and Regulations
      pursuant to subparagraph (1), (4) or (7) of Rule 424(b) of the Rules and
      Regulations or as part of a post-effective amendment to the registration
      statement (including a final form of prospectus).  If the registration
      statement relating to the Shares has not been declared effective under
      the Act by the Commission, the Company will prepare and promptly file an
      amendment to the registration statement, including a final form of
      prospectus, or, if BancAmerica Robertson Stephens, on behalf of the
      several Underwriters, shall agree to the utilization of Rule 434 of the
      Rules and Regulations, the information required to be included in any
      term sheet filed pursuant to Rule 434(b) or (c), as applicable, of the

      Agreement shall mean such registration statement, including financial
      statements, schedules and exhibits, in the form in which it became or
      becomes, as the case may be, effective (including, if the Company omitted
      information from the registration statement pursuant to Rule 430A(a) or
      files a term sheet pursuant to Rule 434 of the Rules and Regulations, the
      information deemed to be a part of the registration statement at the time
      it became effective pursuant to Rule 430A(b) or Rule 434(d) of the Rules
      and Regulations) and, in the event of any amendment thereto or the filing
      of any abbreviated registration statement pursuant to Rule 462(b) of the
      Rules and Regulations relating thereto after the effective date of such
      registration statement, shall also mean (from and after the effectiveness
      of such amendment or the filing of such abbreviated registration
      statement) such registration statement as so amended, together with any
      such abbreviated registration statement.  The term "Prospectus" as used
      in this Agreement shall mean the prospectus relating to the Shares as
      included in such Registration Statement at the time it becomes effective
      (including, if the Company omitted information from the Registration
      Statement pursuant to Rule 430A(a) of the Rules and Regulations, the
      information deemed to be a part of the Registration Statement at the time
      it became effective pursuant to Rule 430A(b) of the Rules and
      Regulations); provided, however, that if in reliance on Rule 434 of the
      Rules and Regulations and with the consent of BancAmerica Robertson
      Stephens, on behalf of the several Underwriters, the Company shall have
      provided to the Underwriters a term sheet pursuant to Rule 434(b) or (c),

      and circulated by the Underwriters to all prospective purchasers of the
      Shares (including the information deemed to be a part of the Registration
      Statement at the time it became effective pursuant to Rule 434(d) of the
      Rules and Regulations).  Notwithstanding the foregoing, if any revised
      prospectus shall be provided to the Underwriters by the Company for use
      in connection with the offering of the Shares that differs from the
      prospectus referred to in the immediately preceding sentence (whether or
      not such revised prospectus is required to be filed with the Commission
      pursuant to Rule 424(b) of the Rules and Regulations), the term
      "Prospectus" shall

      refer to such revised prospectus from and after the time it is first
      provided to the Underwriters for such use.  If in reliance on Rule 434 of
      the Rules and Regulations and with the consent of BancAmerica Robertson
      Stephens, on behalf of the several Underwriters, the Company shall have
      provided to the Underwriters a term sheet pursuant to Rule 434(b) or (c),
      as applicable, prior to the time that a confirmation is sent or given for
      purposes of Section 2(10)(a) of the Act, the Prospectus and the term
      sheet, together, will not be materially different from the prospectus in
      the Registration Statement.

                   (b)    The Commission has not issued any order preventing or
      suspending the use of any Preliminary Prospectus or instituted
      proceedings for that purpose, and each such Preliminary Prospectus has
      conformed in all material respects to the requirements of the Act and the
      Rules and Regulations and, as of its date, has not included any untrue
      statement of a material fact or omitted to state a material fact
      necessary to make the statements therein, in the light of the
      circumstances under which they were made, not misleading; and at the time
      the Registration Statement became or becomes, as the case may be,
      effective and at all times subsequent thereto up to and on the Closing
      Date (hereinafter defined) and on any later date on which Option Shares
      are to be purchased, (i) the Registration Statement and the Prospectus,
      and any amendments or supplements thereto, contained and will contain all
      material information required to be included therein by the Act and the
      Rules and Regulations and will in all material respects conform to the
      requirements of the Act and the Rules and Regulations, (ii) the
      Registration Statement, and any amendments or supplements thereto, did
      not and will not include any untrue statement of a material fact or omit
      to state a material fact required to be stated therein or necessary to
      make the statements therein not misleading, and (iii) the Prospectus, and
      any amendments or supplements thereto, did not and will not include any
      untrue statement of a material fact or omit to state a material fact
      necessary to make the statements therein, in the light of the
      circumstances under which they were made, not misleading; provided,
      however, that none of the representations and warranties contained in
      this subparagraph (b) shall apply to information contained in or omitted
      from the Registration Statement or Prospectus, or any amendment or
      supplement thereto, in reliance upon, and in conformity with, written
      information relating to any Underwriter furnished to the Company by such
      Underwriter specifically for use in the preparation thereof.

      condition (financial or otherwise), earnings, operations, business or
      business prospects; no proceeding has been instituted in any such
      jurisdiction revoking, limiting or curtailing, or seeking to revoke,
      limit or curtail, such power and authority or qualification; the Company
      is in possession of and operating in compliance with all authorizations,
      licenses, certificates, consents, orders and permits from state, federal

      or otherwise that (i) might result in any material adverse change in the
      condition (financial or otherwise), earnings, operations, business or
      business prospects of the Company or might materially and adversely
      affect their properties, assets or rights, (ii) might prevent
      consummation of the transactions contemplated hereby or (iii) is required
      to be disclosed in the Registration Statement or Prospectus and is not so
      disclosed; and there are no agreements, contracts, leases or documents of
      the Company of a character required to be described or referred to in the
      Registration Statement or Prospectus or to be filed as an exhibit to the
      Registration Statement by the Act or the Rules and Regulations that have
      not been accurately described in all material respects in the
      Registration Statement or Prospectus or filed as exhibits to the
      Registration Statement.

                   (f)    All outstanding shares of capital stock of the
      Company (including the Selling Stockholder Shares) have been duly
      authorized and validly issued and are fully paid and nonassessable, have
      been issued in compliance with all federal and state securities laws,
      were not issued in violation of or subject to any preemptive rights or
      other rights to subscribe for or purchase securities, and the authorized
      and outstanding capital stock of the Company is as set forth in the
      Prospectus under the caption "Capitalization" and conforms in all
      material respects to the statements relating thereto contained in the
      Registration Statement and the Prospectus (and such statements correctly
      state the substance of the instruments defining the capitalization of the
      Company); the Firm Shares and the Option Shares to be purchased from the
      Company hereunder have been duly authorized for issuance and sale to the
      Underwriters pursuant to this Agreement and, when issued and delivered by

      refusal or other similar right of stockholders exists with respect to any

      hereunder or the issuance and sale thereof other than those that have
      been expressly waived prior to the date hereof and those that will
      automatically expire upon and will not apply to the consummation of the

      securities or obligations convertible into, or any contracts or
      commitments to issue or sell, shares of its capital stock or any such
      options, rights, convertible securities or obligations.  The description
      of the Company's stock option, stock bonus and other stock plans or
      arrangements, and the options or other rights granted and exercised
      thereunder, set forth in the Prospectus accurately and fairly presents
      the information required to be shown with respect to such plans,

      the Company at the respective dates and for the respective periods to
      which they apply; and all audited financial statements of the Company,
      together with the related schedules and notes, and the unaudited
      financial information, filed with the Commission as part of the
      Registration Statement, have been prepared in accordance with generally

      presented therein.  No other financial statements or schedules are

      any material change in the capital stock or outstanding indebtedness of
      the Company, (v) any dividend or distribution of any kind declared, paid
      or made on the capital stock of the Company, or (vi) any loss or damage
      (whether or not insured) to the property of the Company that has been
      sustained or will have been sustained that has a material adverse effect
      on the condition (financial or otherwise), earnings, operations, business
      or business prospects of the Company.

                   (i)    Except as set forth in the Registration Statement and
      Prospectus, (i) the Company has good and marketable title to all
      properties and assets described in the Registration Statement and
      Prospectus as owned by it, free and clear of any pledge, lien, security
      interest, encumbrance, claim or equitable interest, other than such as

      otherwise), earnings, operations, business or business prospects of the
      Company, (ii) the agreements to which the Company is a party described in

      by applicable bankruptcy, insolvency, reorganization, moratorium or other
      similar laws relating to or affecting creditors' rights generally or by
      general equitable principles and, to the best of the Company's knowledge,
      the other contracting party or parties thereto are not in material breach
      or material default under any of such agreements, and (iii) the Company
      has valid and enforceable leases for all properties described in the
      Registration Statement and Prospectus as leased by it, except as the
      enforcement thereof may be limited by applicable bankruptcy, insolvency,
      reorganization, moratorium or other similar laws relating to or affecting
      creditors' rights generally or by general equitable principles.  Except
      as set forth in the Registration Statement and Prospectus, the Company
      owns or leases all such properties as are necessary to its operations as
      now conducted or as proposed to be conducted.

                   (j)    The Company has timely filed all necessary federal,
      state and foreign income and franchise tax returns and has paid all taxes
      shown thereon as due, and there is no tax deficiency that has been or, to
      the best of the Company's knowledge, might be asserted against the
      Company that might have a material adverse effect on the condition
      (financial or otherwise), earnings, operations, business or business
      prospects of the Company; and all tax liabilities are adequately provided
      for on the books of the Company.

                   (k)    The Company maintains insurance with insurers of
      recognized financial responsibility of the types and in the amounts
      generally deemed adequate for its business and consistent with insurance
      coverage maintained by similar companies in similar businesses, including
      insurance covering real and personal property owned or leased by the
      Company against theft, damage, destruction, acts of vandalism and all
      other risks customarily insured against, all of which insurance is in
      full force and effect; the Company has not been refused any insurance
      coverage sought or applied for; and the Company does not have any reason
      to believe that it will not be able to renew its existing insurance
      coverage as and when such coverage expires or to obtain similar coverage
      from similar insurers as may be necessary to continue its business at a
      cost that would not materially and adversely affect the condition
      (financial or otherwise), earnings, operations, business or business
      prospects of the Company.

                   (l)    To the best of Company's knowledge, no labor
      disturbance by the employees of the Company exists or is imminent; and

      might be expected to result in a material adverse change in the condition
      (financial or otherwise), earnings, operations, business or business
      prospects of the Company.  No collective bargaining agreement exists with
      any of the Company's employees and, to the best of the Company's
      knowledge, no such agreement is imminent.

      all patents, patent rights, inventions, trade secrets, know-how,
      trademarks, service marks, trade names and copyrights that are necessary
      to conduct its businesses as described in the Registration Statement and
      Prospectus; the expiration of any patents, patent rights, trade secrets,
      trademarks, service marks, trade names or copyrights would not have a
      material adverse effect on the condition (financial or otherwise),
      earnings, operations, business or business prospects of the Company; the
      Company has not received any notice of, and has no knowledge of, any
      infringement of or conflict with asserted rights of the Company by others
      with respect to any patent, patent rights, inventions, trade secrets,
      know-how, trademarks, service marks, trade names or copyrights; and the
      Company has not received any notice of, and has no knowledge of, any
      infringement of or conflict with asserted rights of others with respect
      to any patent, patent rights, inventions, trade secrets, know-how,

      the aggregate, if the subject of an unfavorable decision, ruling or
      finding,

      might have a material adverse effect on the condition (financial or
      otherwise), earnings, operations, business or business prospects of the
      Company.

      regulations.

      other materials, if any, permitted by the Act.

                   (q)    The Company has not at any time during the last five
      years (i) made any unlawful contribution to any candidate for foreign
      office or failed to disclose fully any contribution in violation of law

      duties, other than payments required or permitted by the laws of the
      United States or any jurisdiction thereof.

                   (r)    The Company has not taken and will not take, directly
      or indirectly, any action designed to or that might reasonably be
      expected to cause or result in stabilization or manipulation of the price

      Selling Stockholder and each beneficial owner of shares of Common Stock
      has agreed in writing that such person will not, for a period of 180 days
      after the date of the Prospectus (the "Lock-up Period"), offer to sell,
      contract to sell, or otherwise sell, dispose of, loan, pledge or grant
      any rights with respect to (collectively, a "Disposition") 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 (collectively, "Securities") now owned or hereafter acquired
      directly by such person or with respect to which such person has or
      hereafter acquires the power of disposition, otherwise than (i) as a bona
      fide gift or gifts, provided the donee or donees thereof agree in writing
      to be bound by this restriction, (ii) as a distribution to, members or
      partners or stockholders of such person, provided the distributees
      thereof agree in writing to be bound by the terms of this restriction or
      (iii) with the prior written consent of BancAmerica Robertson Stephens.
      The foregoing restriction has been expressly agreed to preclude the
      holder of the Securities from engaging in any hedging or other
      transaction that is designed to or reasonably expected to lead to or
      result in a Disposition of Securities during the Lock-up Period, even if
      such Securities would be disposed of by someone other than such holder.
      Such prohibited hedging or other transactions would include any short
      sale (whether or not against the box) or any purchase, sale or grant of
      any right (including any put or call option) with respect to any
      Securities or with respect to any security (other than a broad-based
      market basket or index) that includes, relates to or derives any
      significant part of its value from the Securities.  Notwithstanding the
      foregoing, this restriction shall not prohibit (i) the sale of Shares to
      the Underwriters pursuant to this Agreement or (ii) resales of shares of
      Common Stock acquired either in the public offering to which the
      Registration Statement relates or in subsequent open-market purchases.

      represents and warrants that it will not release any of its officers,

      designated as a contaminated site under applicable state or local law.

                   (u)    The Company maintains a system of internal accounting
      controls sufficient to provide reasonable assurances that (i)
      transactions are executed in accordance with management's general or

      general or specific authorization and (iv) the recorded accountability

      have valid marketable title to the Shares to be sold by such Selling
      Stockholder, free and clear of any pledge, lien, security interest,

      "Attorney") and a Letter of Transmittal and Custody Agreement (the
      "Custody Agreement") with SCC Communications Corp., as custodian (the
      "Custodian"); each of the Power of Attorney and the Custody Agreement
      constitutes a valid and binding agreement on the part of such Selling
      Stockholder, enforceable in accordance with its terms, except as the
      enforcement thereof may be limited by applicable bankruptcy, insolvency,
      reorganization, moratorium or other similar laws relating to or affecting
      creditors' rights generally or by general equitable principles; and each
      of such Selling Stockholder's Attorneys, acting alone, is authorized to
      execute and deliver this Agreement and the certificate referred to in
      Section 6(h) hereof on behalf of such Selling Stockholder, to determine
      the purchase price to be paid by the several Underwriters to such Selling
      Stockholder as provided in Section 3 hereof, to authorize the delivery of
      the Selling Stockholder Shares and the Option Shares to be sold by such
      Selling Stockholder under this Agreement and to duly endorse (in blank or
      otherwise) the certificate or certificates representing such Shares or a
      stock power or powers with respect thereto, to accept payment therefor,
      and otherwise to act on behalf of such Selling Stockholder in connection
      with this Agreement.

                   (c)    All consents, approvals, authorizations and orders
      required for the execution and delivery by such Selling Stockholder of
      the Power of Attorney and the Custody Agreement, the execution and
      delivery by or on behalf of such Selling Stockholder of this Agreement
      and the sale and delivery of the Selling Stockholder Shares and the
      Option Shares to be sold by such Selling Stockholder under this Agreement
      (other than, at the time of the execution hereof (if the Registration
      Statement has not yet been declared effective by the Commission), the
      issuance of the order of the Commission declaring the Registration
      Statement effective and such consents, approvals, authorizations or
      orders as may be necessary under state or other securities or Blue Sky
      laws) have been obtained and are in full force and effect; such Selling
      Stockholder, if other than a natural person, has been duly organized and
      is validly existing in good standing under the laws of the jurisdiction
      of its organization as the type of entity that it purports to be; and
      such Selling Stockholder has full legal right, power and authority to
      enter into and perform its obligations under this Agreement and such
      Power of Attorney and Custody Agreement, and to sell, assign, transfer
      and deliver the Shares to be sold by such Selling Stockholder under this
      Agreement.

                   (d)    Such Selling Stockholder will not, during the Lock-up
      Period, effect the Disposition of any Securities now owned or hereafter
      acquired directly by such Selling Stockholder or with respect to which
      such Selling Stockholder has or hereafter acquires the power of
      disposition, otherwise than (i) as a bona fide gift or gifts, provided
      the donee or donees thereof agree in writing to be bound by this
      restriction, (ii) as a distribution to limited partners, members or
      stockholders of such Selling Stockholder, provided the distributees
      thereof agree in writing to be bound by the terms of this restriction or

      The foregoing restriction is expressly agreed to preclude the holder of
      the Securities from engaging in any hedging or other transaction that is

      or with respect to any security (other than a broad-based market basket
      or index) that includes, relates to or derives any significant part of
      its value from the





                                       9

      Securities.  Notwithstanding the foregoing, this restriction shall not
      prohibit (i) the sale of Shares to the Underwriters pursuant to this
      Agreement or (ii) resales of shares of Common Stock acquired either in
      the public offering to which the Registration Statement relates or in
      subsequent open-market purchases.  Such Selling Stockholder also agrees
      and consents to the entry of stop transfer instructions with the
      Company's transfer agent against the transfer of Securities held by such
      Selling Stockholder except in compliance with this restriction.

                   (e)    Certificates in negotiable form for all Shares to be
      sold by such Selling Stockholder under this Agreement, together with a
      stock power or powers duly endorsed in blank by such Selling Stockholder,
      have been placed in custody with the Custodian for the purpose of
      effecting delivery hereunder.

                   (f)    This Agreement has been duly authorized by each
      Selling Stockholder that is not a natural person and has been duly
      executed and delivered by or on behalf of such Selling Stockholder and is
      a valid and binding agreement of such Selling Stockholder, enforceable in
      accordance with its terms, except as rights to indemnification hereunder
      may be limited by applicable law and except as the enforcement hereof may
      be limited by bankruptcy, insolvency, reorganization, moratorium or other
      similar laws relating to or affecting creditors' rights generally or by
      general equitable principles; and the performance of this Agreement and
      the consummation of the transactions herein contemplated will not result
      in a breach or violation of any of the terms and provisions of or
      constitute a default under any bond, debenture, note or other evidence of
      indebtedness, or under any lease, contract, indenture, mortgage, deed of
      trust, loan agreement, joint venture or other agreement or instrument to
      which such Selling Stockholder is a party or by which such Selling
      Stockholder, or any Selling Stockholder Shares or any Option Shares to be
      sold by such Selling Stockholder hereunder, may be bound or, to the best
      of such Selling Stockholder's knowledge, result in any violation of any
      law, order, rule, regulation, writ, injunction, judgment or decree of any
      court, government or governmental agency or body, domestic or foreign,
      having jurisdiction over such Selling Stockholder or over the properties
      of such Selling Stockholder, or, if such Selling Stockholder is other
      than a natural person, result in any violation of any provisions of the
      charter, bylaws or other organizational documents of such Selling
      Stockholder.

                   (g)    Such Selling Stockholder has not taken and will not
      take, directly or indirectly, any action designed to or that might
      reasonably be expected to cause or result in stabilization or
      manipulation of the price of the Common Stock to facilitate the sale or
      resale of the Shares.

                   (h)    Such Selling Stockholder has not distributed and will
      not distribute any prospectus or other offering material in connection
      with the offering and sale of the Shares.

      Selling Stockholder relating to such Selling Stockholder and the Selling

                   (j)    Such Selling Stockholder will review the Prospectus
      and will comply with all agreements and satisfy all conditions on its
      part to be complied with or satisfied pursuant to this Agreement on or
      prior to the Closing Date, or any later date on which Option Shares are
      to be purchased, as the case may be, and will advise one of its Attorneys
      and BancAmerica Robertson Stephens prior to the Closing Date or such
      later date on which Option Shares are to be purchased, as the case may
      be, if any statement to be made on behalf of such Selling Stockholder in
      the certificate contemplated by Section 6(h) would be inaccurate if made
      as of the Closing Date or such later date on which Option Shares are to
      be purchased, as the case may be.

                   (k)    Such Selling Stockholder does not have, or has waived
      prior to the date hereof, any preemptive right, co-sale right or right of
      first refusal or other similar right to purchase any of the Shares that

      the Underwriters pursuant to this Agreement; such Selling Stockholder

      satisfied by the participation of such Selling Stockholder in the
      transactions to which this Agreement relates in accordance with the terms
      of this Agreement; and such Selling Stockholder does not own any
      warrants, options or similar rights to acquire, and does not have any
      right or arrangement to acquire, any capital stock, rights, warrants,

      above is untrue or inaccurate in any material respect.

      3.     Purchase, Sale and Delivery of Shares.  On the basis of the
representations, warranties and agreements herein contained, but subject to the
terms and conditions herein set forth, the Company and the Selling Stockholders
agree, severally and not jointly, to sell to the Underwriters, and each
Underwriter agrees, severally and not jointly, to purchase from the Company and
the Selling Stockholders, respectively, at a purchase price of $_____ per
share, the respective number of Company Shares and Selling Stockholder Shares
as set forth opposite the names of the Company and the Selling Stockholders in
Schedule B hereto.  The obligation of each Underwriter to the Company and to
each Selling Stockholder shall be to purchase from the Company or such Selling
Stockholder that number of Company Shares or Selling Stockholder Shares, as the
case may be, that (as nearly as practicable, as determined by you) is in the
same proportion to the number of Company Shares or Selling Stockholder Shares,
as the case may be, set forth opposite the name of the Company or such Selling
Stockholder in Schedule B hereto as the number of Firm Shares set forth
opposite the name of such Underwriter in Schedule A hereto (subject to
adjustment as provided in Section 10) is to the total number of Firm Shares to
be purchased by all the Underwriters under this Agreement.

             The certificates in negotiable form for the Selling Stockholder
Shares have been placed in custody (for delivery under this Agreement) under
the Custody Agreement.  Each Selling Stockholder agrees that the certificates
for the Selling Stockholder Shares of such Selling Stockholder so held in
custody are subject to the interests of the Underwriters hereunder, that the
arrangements made by such Selling Stockholder for such custody, including the
Power of Attorney, is to that extent irrevocable and that the obligations of
such Selling Stockholder hereunder shall not be terminated by the act of such
Selling Stockholder or by operation of law, whether by the death or incapacity
of such Selling Stockholder or the occurrence of any other event, except as
specifically provided herein or in the Custody Agreement.  If any Selling
Stockholder should die or be incapacitated, or if any other such event should
occur, before the





                                       11
<PAGE>   12
delivery of the certificates for the Selling Stockholder Shares hereunder, the
Selling Stockholder Shares to be sold by such Selling Stockholder shall, except
as specifically provided herein or in the Custody Agreement, be delivered by
the Custodian in accordance with the terms and conditions of this Agreement as
if such death, incapacity or other event had not occurred, regardless of
whether the Custodian shall have received notice of such death or other event.

             Delivery of definitive certificates for the Firm Shares to be
purchased by the Underwriters pursuant to this Section 3 shall be made against
payment of the purchase price therefor by the several Underwriters by certified
or official bank check or checks drawn in next-day funds, payable to the order
of the Company with regard to the Shares being purchased from the Company, and
to the order of the Custodian for the respective accounts of the Selling
Stockholders with regard to the Shares being purchased from such Selling
Stockholders (and the Company and such Selling Stockholders agree not to
deposit and to cause the Custodian not to deposit any such check in the bank on
which it is drawn, and not to take any other action with the purpose or effect
of receiving immediately available funds, until the business day following the
date of its delivery to the Company or the Custodian, as the case may be, and,
in the event of any breach of the foregoing, the Company or the Selling
Stockholders, as the case may be, shall reimburse the Underwriters for the
interest lost and any other expenses borne by them by reason of such breach),

Suite 2525, Denver, Colorado (or at such other place as may be agreed upon
among the Representatives, the Company and the Attorneys), at 7 A.M., San
Francisco time, (a) on the third full business day following the first day that
Shares are traded, (b) if this Agreement is executed and delivered after 1:30
P.M., San Francisco time, the fourth full business day following the day that
this Agreement is executed and delivered or (c) at such other time and date not
later than seven full business days following the first day that Shares are
traded as the Representatives, the Company and the Attorneys may determine (or
at such time and date to which payment and delivery shall have been postponed
pursuant to Section 10 hereof), such time and date of payment and delivery
being herein called the "Closing Date"; provided, however, that if the Company
has not made available to the Representatives copies of the Prospectus within
the time provided in Section 4(d) hereof, the Representatives may, in their
sole discretion, postpone the Closing Date until no later than two full
business days following delivery of copies of the Prospectus to the
Representatives.  The certificates for the Firm Shares to be so delivered will
be made available to you at such office or such other location, including in
New York City, as you may reasonably request for checking at least one full
business day prior to the Closing Date and will be in such names and
denominations as you may request, such request to be made at least two full
business days prior to the Closing Date.  If the Representatives so elect,
delivery of the Firm Shares may be made by credit through full fast transfer to
the accounts at The Depository Trust Company designated by the Representatives.

             It is understood that you, individually, and not as the
Representatives of the several Underwriters, may (but shall not be obligated
to) make payment of the purchase price on behalf of any Underwriter or
Underwriters whose check or checks shall not have been received by you prior to
the Closing Date for the Firm Shares to be purchased by such Underwriter or
Underwriters.  Any such payment by you shall not relieve any such Underwriter
or Underwriters of any of its or their obligations hereunder.

             After the Registration Statement becomes effective, the several
Underwriters intend to make an initial public offering (as such term is
described in Section 11 hereof) of the Firm Shares at an initial public
offering price of $_____ per share.  After the initial public offering, the
several Underwriters may, in their discretion, vary the public offering price.

             The information set forth in the last paragraph on the front cover
page (insofar as such information relates to the Underwriters), on the inside
front cover concerning stabilization and over-allotment by the Underwriters,
and under the second, sixth and eighth paragraphs and the third sentence of the
fifth





                                       12

paragraph under the caption "Underwriting" in any Preliminary Prospectus and in
the Prospectus constitutes the only information furnished by the Underwriters
to the Company for inclusion in any Preliminary Prospectus, the Prospectus or
the Registration Statement, and you, on behalf of the respective Underwriters,
represent and warrant to the Company and the Selling Stockholders that the
statements made therein do not include any untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

             several Underwriters that:

      the distribution of the Shares by the Underwriters; it will promptly
      prepare and file with the Commission, and promptly notify you of the
      filing of, any amendments or supplements to the Registration Statement or
      Prospectus that may be necessary to correct any statements or omissions,
      if, at any time when a prospectus relating to the Shares is required to
      be delivered under the Act, any event shall have occurred as a result of
      which the Prospectus or any other prospectus relating to the Shares as
      then in effect would include any untrue statement of a material fact or
      omit to state a material fact necessary to make the statements therein,
      in the light of the circumstances under which they were made, not
      misleading; in case any Underwriter is required to deliver a prospectus
      nine months or more after the effective date of the Registration
      Statement in connection with the sale of the Shares, it will prepare
      promptly upon request, but at the expense of such Underwriter, such
      amendment or amendments to the Registration Statement and such prospectus
      or prospectuses as may be necessary to permit compliance with the
      requirements of Section 10(a)(3) of the Act; and it will file no
      amendment or supplement to the Registration Statement or Prospectus that
      shall not previously have been submitted to you a reasonable time prior
      to the proposed filing thereof or to which you shall reasonably object in
      writing, subject, however, to compliance with the Act and the Rules and
      Regulations and the provisions of this Agreement.

             (b)   The Company will advise you, promptly after it shall receive
      notice or obtain knowledge, of the issuance of any stop order by the
      Commission suspending the effectiveness of the Registration Statement or
      of the initiation or threat of any proceeding for that purpose; and it
      will promptly use its best efforts to prevent the issuance of any stop
      order or to obtain its withdrawal at the earliest possible moment if such
      stop order should be issued.

             (c)   The Company will use its best efforts to qualify the Shares
      for offering and sale under the securities laws of such jurisdictions as
      you may designate and to continue such qualifications in effect for so
      long as may be required for purposes of the distribution of the Shares,
      except that the Company shall not be required in connection therewith or
      as a condition thereof to qualify as a foreign corporation or to execute
      a general consent to service of process in any jurisdiction in which it
      is not otherwise required to be so qualified or to so execute a general
      consent to service of process.  In each jurisdiction in which the Shares
      shall have been qualified as above provided, the Company will make and
      file such statements and reports in each year as are or may be required
      by the laws of such jurisdiction.

             (d)   The Company will furnish to you, as soon as available, and,
      in the case of the Prospectus and any term sheet or abbreviated term
      sheet under Rule 434, in no event later than the first full business day
      following the first day that Shares are traded, copies of the
      Registration Statement (three of which will be signed and which will
      include all exhibits), each Preliminary Prospectus, the Prospectus and
      any amendments or supplements to such documents, including any prospectus
      prepared to permit compliance with Section 10(a)(3) of the Act, all in
      such quantities as you may from time to time reasonably request.
      Notwithstanding the foregoing, if BancAmerica Robertson Stephens, on
      behalf of the several Underwriters, shall agree to the utilization of
      Rule 434 of the Rules and Regulations, the Company shall provide to you
      copies of a Preliminary Prospectus updated in all respects through the
      date specified by you in such quantities as you may from time to time
      reasonably request.

             (e)   The Company will make generally available to its
      securityholders as soon as practicable, but in any event not later than
      the forty-fifth day following the end of the fiscal quarter first
      occurring after the first anniversary of the effective date of the
      Registration Statement, an earnings statement (which will be in
      reasonable detail but need not be audited) complying with the provisions
      of Section 11(a) of the Act and covering a twelve-month period beginning
      after the effective date of the Registration Statement.

             (f)   During a period of five years after the date hereof, the
      Company will furnish to its stockholders as soon as practicable after the
      end of each respective period, annual reports (including financial
      statements audited by independent certified public accountants) and
      unaudited quarterly reports of operations for each of the first three
      quarters of the fiscal year, and will furnish to you and the other
      several Underwriters hereunder, upon request (i) concurrently with
      furnishing such reports to its stockholders, statements of operations of
      the Company for each of the first three quarters in the form furnished to
      the Company's stockholders, (ii) concurrently with furnishing to its
      stockholders, a balance sheet of the Company as of the end of such fiscal
      year, together with statements of operations, of stockholders' equity,
      and of cash flows of the Company for such fiscal year, accompanied by a
      copy of the certificate or report thereon of independent certified public
      accountants, (iii) as soon as they are available, copies of all reports
      (financial or other) mailed to stockholders, (iv) as soon as they are
      available, copies of all reports and financial statements furnished to or
      filed





                                       14
<PAGE>   15
      with the Commission, any securities exchange or the National Association
      of Securities Dealers, Inc. (the "NASD"), (v) every material press
      release and every material news item or article in respect of the Company
      or its affairs that was generally released to stockholders or prepared by
      the Company, and (vi) any additional information of a public nature
      concerning the Company, or its business that you may reasonably request.
      During such five-year period, if the Company shall have any active
      subsidiaries, the foregoing financial statements shall be on a
      consolidated basis to the extent that the accounts of the Company and
      such subsidiaries are consolidated and shall be accompanied by similar
      financial statements for any significant subsidiary that is not so
      consolidated.

             (g)   The Company will apply the net proceeds from the sale of the
      Shares being sold by it in the manner set forth under the caption "Use of
      Proceeds" in the Prospectus.

             (h)   The Company will maintain a transfer agent and, if necessary
      under the jurisdiction of incorporation of the Company, a registrar
      (which may be the same entity as the transfer agent) for its Common
      Stock.

             (i)   If the transactions contemplated hereby are not consummated
      by reason of any failure, refusal or inability on the part of the Company
      or any Selling Stockholder to perform any agreement on their respective
      parts to be performed hereunder or to fulfill any condition of the
      Underwriters' obligations hereunder, or if the Company shall terminate
      this Agreement pursuant to Section 11(a) hereof, or if the Underwriters
      shall terminate this Agreement pursuant to Section 11(b)(i), the Company
      will reimburse the several Underwriters for all out-of- pocket expenses
      (including fees and disbursements of Underwriters' Counsel) incurred by
      the Underwriters in investigating or preparing to market or marketing the
      Shares.

             (j)   If at any time during the ninety-day period after the
      Registration Statement becomes effective, any rumor, publication or event
      relating to or affecting the Company shall occur as a result of which in
      your opinion the market price of the Common Stock has been or is likely
      to be materially affected (regardless of whether such rumor, publication
      or event necessitates a supplement to or amendment of the Prospectus),
      the Company will, after written notice from you advising the Company to
      the effect set forth above, forthwith prepare, consult with you
      concerning the substance of and disseminate a press release or other
      public statement, reasonably satisfactory to you, responding to or
      commenting on such rumor, publication or event.

             (k)   During the Lock-up Period, the Company will not, without the
      prior written consent of BancAmerica Robertson Stephens, effect the
      Disposition of, directly or indirectly, any Securities other than the
      sale of the Company Shares and the Option Shares to be sold by the
      Company hereunder and the Company's issuance of options or Common Stock
      under the Company's presently authorized 1990 Stock Option Plan, as
      amended, 1998 Stock Incentive Plan or 1998 Employee Stock Purchase Plan.

             (l)   During a period of ninety days from the effective date of
      the Registration Statement, the Company will not file a registration
      statement registering shares under the Company's presently authorized
      1990 Stock Option Plan, as amended, 1998 Stock Incentive Plan or 1998
      Employee Stock Purchase Plan or any other benefit plan.

      5.     Expenses.

             (a)   The Company and the Selling Stockholders agree with each
      Underwriter that:





                                       15
<PAGE>   16
                   (i)    The Company and the Selling Stockholders will pay and
             bear all costs and expenses in connection with the preparation,
             printing and filing of the Registration Statement (including
             financial statements, schedules and exhibits), Preliminary
             Prospectuses and the Prospectus and any amendments or supplements
             thereto; the issuance and delivery of the Shares hereunder to the
             several Underwriters, including transfer taxes, if any, the cost
             of all certificates representing the Shares, and transfer agents'
             and registrars' fees; the fees and disbursements of counsel for
             the Company; all fees and other charges of the Company's
             independent certified public accountants; the cost of furnishing
             to the several Underwriters copies of the Registration Statement
             (including appropriate exhibits), Preliminary Prospectuses and the
             Prospectus and any amendments or supplements to any of the
             foregoing; NASD filing fees and the cost of qualifying the Shares
             under the laws of such jurisdictions as you may designate
             (including filing fees and fees and disbursements of Underwriters'
             Counsel in connection with such NASD filings and Blue Sky
             qualifications); and all other expenses directly incurred by the
             Company and the Selling Stockholders in connection with the
             performance of their obligations hereunder.  Any additional
             expenses incurred as a result of the sale of the Shares by the
             Selling Stockholders will be borne collectively by the Company and
             the Selling Stockholders.  The provisions of this Section 5(a)(i)
             are intended to relieve the Underwriters from the payment of the
             expenses and costs that the Selling Stockholders and the Company
             hereby agree to pay, but shall not affect any agreement that the
             Selling Stockholders and the Company may make, or may have made,
             for the sharing of any of such expenses and costs.  Such
             agreements shall not impair the obligations of the Company and the
             Selling Stockholders hereunder to the several Underwriters.

                   (ii)   In addition to its other obligations under Section
             8(a) hereof, the Company agrees that, as an interim measure during
             the pendency of any claim, action, investigation, inquiry or other
             proceeding described in Section 8(a) hereof, it will reimburse the
             Underwriters on a monthly basis for all reasonable legal or other
             expenses incurred in connection with investigating or defending
             any such claim, action, investigation, inquiry or other
             proceeding, notwithstanding the absence of a judicial
             determination as to the propriety and enforceability of the
             Company's obligation to reimburse the Underwriters for such
             expenses and the possibility that such payments might later be
             held to have been improper by a court of competent jurisdiction.
             To the extent that any such interim reimbursement payment is so
             held to have been improper, the Underwriters shall promptly return
             such payment to the Company together with interest, compounded
             daily, determined on the basis of the prime rate (or other
             commercial lending rate for borrowers of the highest credit
             standing) listed from time to time in The Wall Street Journal that
             represents the base rate on corporate loans posted by a
             substantial majority of the nation's thirty largest banks (the
             "Prime Rate").  Any such interim reimbursement payments that are
             not made to the Underwriters within thirty days of a request for
             reimbursement shall bear interest at the Prime Rate from the date
             of such request.

                   (iii)  In addition to their other obligations under Section
             8(b) hereof, each Selling Stockholder agrees that, as an interim
             measure during the pendency of any claim, action, investigation,
             inquiry or other proceeding described in Section 8(b) hereof
             relating to such Selling Stockholder, it will reimburse the
             Underwriters on a monthly basis for all reasonable legal or other
             expenses incurred in connection with investigating or defending
             any such claim, action, investigation, inquiry or other
             proceeding, notwithstanding the absence of a judicial
             determination as to the propriety and enforceability of such
             Selling Stockholder's obligation to reimburse the Underwriters for
             such expenses and the possibility that such payments might later
             be held to have been improper by a court of competent
             jurisdiction.  To the extent that any such interim reimbursement
             payment is so held to have been improper, the Underwriters shall
             promptly return such payment to the Selling Stockholders, together
             with interest, compounded





                                       16
<PAGE>   17
             daily, determined on the basis of the Prime Rate.  Any such
             interim reimbursement payments that are not made to the
             Underwriters within thirty days of a request for reimbursement
             shall bear interest at the Prime Rate from the date of such
             request.

             (b)   In addition to their other obligations under Section 8(c)
      hereof, the Underwriters severally and not jointly agree that, as an
      interim measure during the pendency of any claim, action, investigation,
      inquiry or other proceeding described in Section 8(c) hereof, they will
      reimburse the Company and each Selling Stockholder on a monthly basis for
      all reasonable legal or other expenses incurred in connection with
      investigating or defending any such claim, action, investigation, inquiry
      or other proceeding, notwithstanding the absence of a judicial
      determination as to the propriety and enforceability of the Underwriters'
      obligation to reimburse the Company and each such Selling Stockholder for
      such expenses and the possibility that such payments might later be held
      to have been improper by a court of competent jurisdiction.  To the
      extent that any such interim reimbursement payment is so held to have
      been improper, the Company and each such Selling Stockholder shall
      promptly return such payment to the Underwriters together with interest,
      compounded daily, determined on the basis of the Prime Rate.  Any such
      interim reimbursement payments that are not made to the Company and each
      such Selling Stockholder within thirty days of a request for
      reimbursement shall bear interest at the Prime Rate from the date of such
      request.

             (c)   It is agreed that any controversy arising out of the
      operation of the interim reimbursement arrangements set forth in Sections
      5(a)(ii), 5(a)(iii) and 5(b) hereof, including the amounts of any
      requested reimbursement payments, the method of determining such amounts
      and the basis on which such amounts shall be apportioned among the
      reimbursing parties, shall be settled by arbitration conducted under the
      provisions of the Constitution and Rules of the Board of Governors of the
      New York Stock Exchange, Inc. or pursuant to the Code of Arbitration
      Procedure of the NASD.  Any such arbitration must be commenced by service
      of a written demand for arbitration or a written notice of intention to
      arbitrate, therein electing the arbitration tribunal.  In the event the
      party demanding arbitration does not make such designation of an
      arbitration tribunal in such demand or notice, then the party responding
      to said demand or notice is authorized to do so.  Any such arbitration
      will be limited to the operation of the interim reimbursement provisions
      contained in Sections 5(a)(ii), 5(a)(iii) and 5(b) hereof and will not
      resolve the ultimate propriety or enforceability of the obligation to
      indemnify for expenses that is created by the provisions of Sections
      8(a), 8(b) and 8(c) hereof or the obligation to contribute to expenses
      that is created by the provisions of Section 8(e) hereof.

      6.     Conditions of Underwriters' Obligations.  The obligations of the
several Underwriters to purchase and pay for the Shares as provided herein
shall be subject to the accuracy, as of the date hereof and the Closing Date
and any later date on which Option Shares are to be purchased, as the case may
be, of the representations and warranties of the Company and the Selling
Stockholders herein, to the performance by the Company and the Selling
Stockholders of their respective obligations hereunder and to the following
additional conditions:

             (a)   The Registration Statement shall have become effective not
      later than 2 P.M., San Francisco time, on the date following the date of
      this Agreement, or such later date as shall be consented to in writing by
      you; and no stop order suspending the effectiveness thereof shall have
      been issued and no proceedings for that purpose shall have been initiated
      or, to the knowledge of the Company, any Selling Stockholder or any
      Underwriter, threatened by the Commission, and any request of the
      Commission for additional information (to be included in the Registration
      Statement or the Prospectus or otherwise) shall have been complied with
      to the satisfaction of Underwriters' Counsel.





                                       17
<PAGE>   18
             (b)   All corporate proceedings and other legal matters in
      connection with this Agreement, the form of Registration Statement and
      the Prospectus, and the registration, authorization, issue, sale and
      delivery of the Shares, shall have been reasonably satisfactory to
      Underwriters' Counsel, and Underwriters' Counsel shall have been
      furnished with such papers and information as they may reasonably have
      requested to enable them to pass upon the matters referred to in this
      Section.

             (c)   Subsequent to the execution and delivery of this Agreement
      and prior to the Closing Date, or any later date on which Option Shares
      are to be purchased, as the case may be, there shall not have been any
      change in the condition (financial or otherwise), earnings, operations,
      business or business prospects of the Company from that set forth in the
      Registration Statement or Prospectus that, in your sole judgment, is
      material and adverse and that makes it, in your sole judgment,
      impracticable or inadvisable to proceed with the public offering of the
      Shares as contemplated by the Prospectus.

             (d)   You shall have received on the Closing Date and on any later
      date on which Option Shares are to be purchased, as the case may be, the
      following opinion of Brobeck, Phleger & Harrison LLP, special counsel for
      the Company and counsel for the Selling Stockholders, dated the Closing
      Date or such later date on which Option Shares are to be purchased,
      addressed to the Underwriters and with reproduced copies or signed
      counterparts thereof for each of the Underwriters, to the effect that:

                 (i)    The Company has been duly incorporated and is validly
           existing as a corporation in good standing under the laws of the
           State of Delaware.

                 (ii)   The Company has the corporate power and authority to
           own, lease and operate its properties and to conduct its business as
           described in the Prospectus.

                 (iii)  The Company is duly qualified to do business as a
           foreign corporation and is in good standing in each jurisdiction, if
           any, in which the ownership or leasing of its properties or the
           conduct of its business requires such qualification, except where
           the failure to be so qualified or be in good standing would not have
           a material adverse effect on the condition (financial or otherwise),
           earnings, operations or business of the Company.  To such counsel's
           knowledge, the Company does not own or control, directly or
           indirectly, any corporation, association or other entity.

                 (iv)   The authorized, issued and outstanding capital stock of
           the Company is as set forth in the Prospectus under the caption
           "Capitalization" as of the dates stated therein.  The issued and
           outstanding shares of capital stock of the Company (including the
           Selling Stockholder Shares) have been duly and validly issued and
           are fully paid and nonassessable (assuming that the Company has
           received payment for such shares as contemplated by the votes of the
           Board of Directors of the Company approving such issuances) and, to
           such counsel's knowledge, have not been issued in violation of or
           subject to any preemptive right, co-sale right, registration right,
           right of first refusal or other similar right.

                 (v)    The Firm Shares or the Option Shares, as the case may
           be, to be issued by the Company pursuant to the terms of this
           Agreement have been duly authorized and, upon issuance and delivery
           against payment therefor in accordance with the terms hereof, will
           be duly and validly issued and fully paid and nonassessable, and
           will not have been issued in violation of or subject to any
           preemptive right, co-sale right, registration right, right of first
           refusal or other similar right.





                                       18
<PAGE>   19
                 (vi)   The Company has the corporate power and authority to
           enter into this Agreement and to issue, sell and deliver to the
           Underwriters the Shares to be issued and sold by it hereunder.

                 (vii)  This Agreement has been duly authorized by all
           necessary corporate action on the part of the Company and has been
           duly executed and delivered by the Company and, assuming due
           authorization, execution and delivery by you, is a valid and binding
           agreement of the Company, enforceable in accordance with its terms,
           except insofar as indemnification provisions may be limited by
           applicable law and except as enforceability may be limited by
           bankruptcy, insolvency, reorganization, moratorium or similar laws
           relating to or affecting creditors' rights generally or by general
           equitable principles.

                 (viii) The Registration Statement has become effective under
           the Act, and to such 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 threatened under the Act.

                 (ix)   The Registration Statement and the Prospectus, and each
           amendment or supplement thereto (other than the financial
           statements, including supporting schedules, and financial data
           derived therefrom, as to which such counsel need express no
           opinion), as of the effective date of the Registration Statement,
           complied as to form in all material respects with the requirements
           of the Act and the applicable Rules and Regulations.

                 (x)    The information in the Prospectus under the caption
           "Description of Capital Stock," to the extent that it constitutes
           matters of law or legal conclusions, has been reviewed by such
           counsel and is a fair summary of such matters and conclusions; and
           the forms of certificates evidencing the Common Stock and filed as
           exhibits to the Registration Statement comply with the Delaware
           General Corporation Law.

                 (xi)   The description in the Registration Statement and the
           Prospectus of the certificate of incorporation and bylaws of the
           Company and of statutes are accurate and fairly present the
           information required to be presented by the Act and the applicable
           Rules and Regulations.

                 (xii)  To such counsel's knowledge, there are no agreements,
           contracts, leases or documents to which the Company is a party of a
           character required to be described or referred to in the
           Registration Statement or Prospectus or to be filed as an exhibit to
           the Registration Statement that are not described or referred to
           therein or filed as required.

                 (xiii) The performance of this Agreement and the consummation
           of the transactions herein contemplated (other than performance of
           the Company's indemnification obligations hereunder, concerning
           which no opinion need be expressed) will not (a) result in any
           violation of the Company's certificate of incorporation or bylaws or
           (b) to such counsel's knowledge, result in a material breach or
           violation of any of the terms and provisions of, or constitute a
           default under, (1) any bond, debenture, note or other evidence of
           indebtedness, or any lease, contract, indenture, mortgage, deed of
           trust, loan agreement, joint venture or other agreement or
           instrument known to such counsel to which the Company is a party or
           by which its properties are bound, (2) any applicable statute, rule
           or regulation known to such counsel or (3) any order, writ or decree
           known to such counsel of any court, government or governmental
           agency or body having jurisdiction over the Company or any of its
           properties or operations.

                 (xiv)  No consent, approval, authorization or order of or
           qualification with any court, government or governmental agency or
           body having jurisdiction over the Company or any of its properties
           or operations is necessary in connection with the consummation by
           the Company of the transactions herein contemplated, except such as
           have been obtained under the Act or such as may be required under
           state or other securities or Blue Sky laws in connection with the
           purchase and the distribution of the Shares by the Underwriters.

                 (xv)   To such counsel's knowledge, there are no legal or
           governmental proceedings pending or threatened against the Company
           of a character required to be disclosed in the Registration
           Statement or the Prospectus by the Act or the Rules and Regulations,
           other than those described therein.

                 (xvi)  To such counsel's knowledge, the Company is not
           presently (a) in material violation of its certificate of
           incorporation or bylaws or (b) in material breach of any applicable
           statute, rule or regulation known to such counsel or, to such
           counsel's knowledge, any order, writ or decree of any court or
           governmental agency or body having jurisdiction over the Company or
           any of its properties or operations.

                 (xvii) To such counsel's knowledge, except as set forth in the
           Registration Statement and Prospectus, no holders of Common Stock or
           other securities of the Company have registration rights with
           respect to securities of the Company and, except as set forth in the
           Registration Statement and Prospectus, all holders of securities of
           the Company having rights known to such counsel to registration of
           such shares of Common Stock or other securities, because of the
           filing of the Registration Statement by the Company have, with
           respect to the offering contemplated thereby, waived such rights or
           such rights have expired by reason of lapse of time following
           notification of the Company's intent to file the Registration
           Statement or have included securities in the Registration Statement
           pursuant to the exercise of and in full satisfaction of such rights.

                 (xviii)    Each Selling Stockholder that is not a natural
           person has full right, power and authority to enter into and to
           perform its obligations under the Power of Attorney and Custody
           Agreement to be executed and delivered by it in connection with the
           transactions contemplated herein.  The Power of Attorney and Custody
           Agreement of each Selling Stockholder that is not a natural person
           has been duly authorized by such Selling Stockholder; the Power of
           Attorney and Custody Agreement of each Selling Stockholder has been
           duly executed and delivered by or on behalf of such Selling
           Stockholder; and the Power of Attorney and Custody Agreement of each
           Selling Stockholder constitutes the valid and binding agreement of
           such Selling Stockholder, enforceable in accordance with its terms,
           except as the enforcement thereof may be limited by bankruptcy,
           insolvency, reorganization, moratorium or other similar laws
           relating to or affecting creditors' rights generally or by general
           equitable principles.

                 (xix)  Each of the Selling Stockholders has full right, power
           and authority to enter into and to perform its obligations under
           this Agreement and to sell, transfer, assign and deliver the Shares
           to be sold by such Selling Stockholder hereunder.

                 (xx)   This Agreement has been duly authorized by each Selling
           Stockholder that is not a natural person and has been duly executed
           and delivered by or on behalf of each Selling Stockholder.

                 (xxi)  Upon the delivery of and payment for the Shares as
           contemplated in this Agreement, each of the Underwriters will
           receive valid marketable title to the Shares purchased by it from





                                       20
<PAGE>   21
           such Selling Stockholder, free and clear of any pledge, lien,
           security interest, encumbrance, claim or equitable interest.  In
           rendering such opinion, such counsel may assume that the
           Underwriters are without notice of any defect in the title of the
           Shares being purchased from the Selling Stockholders.

                 In addition, such counsel shall state that such counsel has
      participated in conferences with officials and other representatives of
      the Company, the Representatives, Underwriters' Counsel and the
      independent certified public accountants of the Company, at which such
      conferences the contents of the Registration Statement and Prospectus and
      related matters were discussed, and although they have not verified the
      accuracy or completeness of the statements contained in the Registration
      Statement or the Prospectus, nothing has come to the attention of such
      counsel that leads them to believe that, at the time the Registration
      Statement became effective and at all times subsequent thereto up to and
      on the Closing Date and on any later date on which Option Shares are to
      be purchased, the Registration Statement and any amendment or supplement
      thereto (other than the financial statements, including supporting
      schedules, and other financial and statistical information derived
      therefrom, as to which such counsel need express no comment) contained
      any untrue statement of a material fact or omitted to state a material
      fact required to be stated therein or necessary to make the statements
      therein not misleading, or at the Closing Date or any later date on which
      the Option Shares are to be purchased, as the case may be, the
      Registration Statement, the Prospectus and any amendment or supplement
      thereto (except as aforesaid) contained any untrue statement of a
      material fact or omitted to state a material fact necessary to make the
      statements therein, in the light of the circumstances under which they
      were made, not misleading.

                 Counsel rendering the foregoing opinion may rely as to
      questions of law not involving the laws of the United States or the State
      of California or Colorado or the corporate law of the State of Delaware
      upon opinions of local counsel, and as to questions of fact upon
      representations or certificates of officers of the Company, the Selling
      Stockholders or officers of the Selling Stockholders (when the Selling
      Stockholder is not a natural person), and of government officials, in
      which case their opinion is to state that they are so relying and that
      they have no knowledge of any material misstatement or inaccuracy in any
      such opinion, representation or certificate.  Copies of any opinion,
      representation or certificate so relied upon shall be delivered to you,
      as Representatives of the Underwriters, and to Underwriters' Counsel.

           (e)   You shall have received on the Closing Date and on any later
      date on which Option Shares are to be purchased, as the case may be, the
      following opinion of Ireland, Stapleton, Pryor & Pascoe, P.C., general
      counsel for the Company, dated the Closing Date or such later date on
      which Option Shares are to be purchased, addressed to the Underwriters
      and with reproduced copies or signed counterparts thereof for each of the
      Underwriters, to the effect that:

                 (i)    To such counsel's knowledge, the Company does not own
           or control, directly or indirectly, any corporation, association or
           other entity.

                 (ii)   To such counsel's knowledge, none of the issued and
           outstanding shares of capital stock of the Company (including the
           Selling Stockholder Shares) have been issued in violation of or
           subject to any preemptive right, co-sale right, registration right,
           right of first refusal or other similar right.

                 (iii)  To such counsel's knowledge, there are no agreements,
           contracts, leases or documents to which the Company is a party of a
           character required to be described or referred to





                                       21
<PAGE>   22
           in the Registration Statement or Prospectus or to be filed as an
           exhibit to the Registration Statement that are not described or
           referred to therein or filed as required.

                 (iv)   To such counsel's knowledge, the performance of this
           Agreement and the consummation of the transactions herein
           contemplated (other than performance of the Company's
           indemnification obligations hereunder, concerning which no opinion
           need be expressed) will not result in a material breach or violation
           of any of the terms and provisions of, or constitute a default
           under, (1) any bond, debenture, note or other evidence of
           indebtedness, or any lease, contract, indenture, mortgage, deed of
           trust, loan agreement, joint venture or other agreement or
           instrument known to such counsel to which the Company is a party or
           by which its properties are bound, (2) any applicable statute, rule
           or regulation known to such counsel or (3) any order, writ or decree
           known to such counsel of any court, government or governmental
           agency or body having jurisdiction over the Company or any of its
           properties or operations.

                 (v)    To such counsel's knowledge, there are no legal or
           governmental proceedings pending or threatened against the Company
           of a character required to be disclosed in the Registration
           Statement or the Prospectus by the Act or the Rules and Regulations,
           other than those described therein.

                 (vi)   To such counsel's knowledge, the Company is not
           presently (a) in material violation of its certificate of
           incorporation or bylaws or (b) in material breach of any applicable
           statute, rule or regulation known to such counsel or, to such
           counsel's knowledge, any order, writ or decree of any court or
           governmental agency or body having jurisdiction over the Company or
           any of its properties or operations.

                 (vii)  To such counsel's knowledge, except as set forth in the
           Registration Statement and Prospectus, no holders of Common Stock or
           other securities of the Company have registration rights with
           respect to securities of the Company and, except as set forth in the
           Registration Statement and Prospectus, all holders of securities of
           the Company having rights known to such counsel to registration of
           such shares of Common Stock or other securities, because of the
           filing of the Registration Statement by the Company have, with
           respect to the offering contemplated thereby, waived such rights or
           such rights have expired by reason of lapse of time following
           notification of the Company's intent to file the Registration
           Statement or have included securities in the Registration Statement
           pursuant to the exercise of and in full satisfaction of such rights.

                 In addition, such counsel shall state that such counsel has
      participated in certain conferences with officials and other
      representatives of the Company, the Representatives, Underwriters'
      Counsel and the independent certified public accountants of the Company
      (which conferences did not constitute all of the conferences held by such
      parties with respect to the preparation of the Registration Statement),
      at which such conferences the contents of the Registration Statement and
      Prospectus and related matters were discussed, and although they have not
      verified the accuracy or completeness of the statements contained in the
      Registration Statement or the Prospectus, nothing has come to the
      attention of such counsel that leads them to believe, based upon such
      conferences and such counsel's prior experience with the Company's
      business, that, at the time the Registration Statement became effective
      and at all times subsequent thereto up to and on the Closing Date and on
      any later date on





                                       22
<PAGE>   23
      which Option Shares are to be purchased, the Registration Statement and
      any amendment or supplement thereto (other than the financial statements,
      including supporting schedules, and other financial and statistical
      information derived therefrom, as to which such counsel need express no
      comment) contained any untrue statement of a material fact or omitted to
      state a material fact required to be stated therein or necessary to make
      the statements therein not misleading, or at the Closing Date or any
      later date on which the Option Shares are to be purchased, as the case
      may be, the Registration Statement, the Prospectus and any amendment or
      supplement thereto (except as aforesaid) contained any untrue statement
      of a material fact or omitted to state a material fact necessary to make
      the statements therein, in the light of the circumstances under which
      they were made, not misleading.

                 Counsel rendering the foregoing opinion may rely as to
      questions of law not involving the laws of the United States or the State
      of Colorado or the corporate law of the State of Delaware upon opinions
      of local counsel, and as to questions of fact upon representations or
      certificates of officers of the Company and of government officials, in
      which case their opinion is to state that they are so relying and that
      they have no knowledge of any material misstatement or inaccuracy in any
      such opinion, representation or certificate.  Copies of any opinion,
      representation or certificate so relied upon shall be delivered to you,
      as Representatives of the Underwriters, and to Underwriters' Counsel.

           (f)   You shall have received on the Closing Date and on any later
      date on which Option Shares are to be purchased, as the case may be, an
      opinion of Underwriters' Counsel, in form and substance satisfactory to
      you, with respect to the sufficiency of all such corporate proceedings
      and other legal matters relating to this Agreement and the transactions
      contemplated hereby as you may reasonably require, and the Company shall
      have furnished to Underwriters' Counsel such documents as they may have
      requested for the purpose of enabling them to pass upon such matters.

           (g)   You shall have received on the Closing Date and on any later
      date on which Option Shares are to be purchased, as the case may be, a
      letter from Arthur Andersen LLP addressed to the Underwriters, dated the
      Closing Date or such later date on which Option Shares are to be
      purchased, as the case may be, confirming that they are independent
      certified public accountants with respect to the Company within the
      meaning of the Act and the applicable published Rules and Regulations and
      based upon the procedures described in such letter delivered to you
      concurrently with the execution of this Agreement (herein called the
      "Original Letter"), but carried out to a date not more than five business
      days prior to the Closing Date or such later date on which Option Shares
      are to be purchased, as the case may be, (i) confirming, to the extent
      true, that the statements and conclusions set forth in the Original
      Letter are accurate as of the Closing Date or such later date on which
      Option Shares are to be purchased, as the case may be, and (ii) setting
      forth any revisions and additions to the statements and conclusions set
      forth in the Original Letter that are necessary to reflect any changes in
      the facts described in the Original Letter since the date of such letter,
      or to reflect the availability of more recent financial statements, data
      or information.  The letter shall not disclose any change in the
      condition (financial or otherwise), earnings, operations, business or
      business prospects of the Company from that set forth in the Registration
      Statement or Prospectus that, in your sole judgment, is material and
      adverse and that makes it, in your sole judgment, impracticable or
      inadvisable to proceed with the public offering of the Shares as
      contemplated by the Prospectus.  The Original Letter from Arthur Andersen
      LLP shall be addressed to or for the use of the Underwriters in form and
      substance satisfactory to the Underwriters and shall (i) represent that
      they are independent certified public accountants with respect to the
      Company within the meaning of the Act and the applicable published Rules
      and Regulations, (ii) set forth their opinion with respect to their
      examination of the balance sheet of the Company as of December 31, 1997
      and related statements of operations, stockholders' equity, and cash
      flows for the twelve months ended December 31, 1997, and (iii) address
      other matters agreed upon by Arthur Andersen LLP and you.  In addition,
      you shall have received from Arthur Andersen LLP a letter addressed to
      the Company and made available to you for the use of the Underwriters
      stating that their review of the Company's system of internal accounting
      controls, to the extent they deemed necessary in establishing the scope
      of their examination of the Company's financial statements as of December
      31, 1997, did not disclose any weaknesses in internal controls that they
      considered to be material weaknesses.

           (h)   You shall have received on the Closing Date and on any later
      date on which Option Shares are to be purchased, as the case may be, a
      certificate of the Company, dated the Closing Date or such later date on
      which Option Shares are to be purchased, as the case may be, signed by
      the Chief Executive Officer and Chief Financial Officer of the Company,
      to the effect that, and you shall be satisfied that:

                 (i)    The representations and warranties of the Company in
           this Agreement are true and correct, as if made on and as of the
           Closing Date or any later date on which Option Shares are to be
           purchased, as the case may be, and the Company has complied with all
           the agreements and satisfied all the conditions on its part to be
           performed or satisfied at or prior to the Closing Date or any later
           date on which Option Shares are to be purchased, as the case may be;

                 (ii)   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 threatened under the
           Act;

                 (iii)  When the Registration Statement became effective and at
           all times subsequent thereto up to the delivery of such certificate,
           the Registration Statement and the Prospectus, and any amendments or
           supplements thereto, contained all material information required to
           be included therein by the Act and the Rules and Regulations and in
           all material respects conformed to the requirements of the Act and
           the Rules and Regulations, the Registration Statement, and any
           amendment or supplement thereto, did not and does not include any
           untrue statement of a material fact or omit to state a material fact
           required to be stated therein or necessary to make the statements
           therein not misleading, the Prospectus, and any amendment or
           supplement thereto, did not and does not include any untrue
           statement of a material fact or omit to state a material fact
           necessary to make the statements therein, in the light of the
           circumstances under which they were made, not misleading, and, since
           the effective date of the Registration Statement, there has occurred
           no event required to be set forth in an amended or supplemented
           Prospectus that has not been so set forth; and

                 (iv)   Subsequent to the respective dates as of which
           information is given in the Registration Statement and Prospectus,
           there has not been (a) any material adverse change in the condition
           (financial or otherwise), earnings, operations, business or business
           prospects of the Company, (b) any transaction that is material to
           the Company, except transactions entered into in the ordinary course
           of business, (c) any material obligation, direct or contingent,
           incurred by the Company, except obligations incurred in the ordinary
           course of business, (d) any change in the capital stock or
           outstanding indebtedness of the Company that is material to the
           Company, (e) any dividend or distribution of any kind declared, paid
           or made on the capital stock of the Company, or (f) any loss or
           damage (whether or not insured) to the property of the Company that
           has been sustained or will have been sustained and that has a
           material adverse effect on the condition (financial or otherwise),
           earnings, operations, business or business prospects of the Company.

           (i)   You shall be satisfied that, and you shall have received a
      certificate, dated the Closing Date, or any later date on which Option
      Shares are to be purchased, as the case may be, from the Attorneys for
      each Selling Stockholder to the effect that, as of the Closing Date, or
      any later date on which Option Shares are to be purchased, as the case
      may be, they have not been informed that:





                                       24

                 (i)    The representations and warranties made by such Selling
           Stockholder herein are not true or correct in any material respect
           on the Closing Date or on any later date on which Option Shares are
           to be purchased, as the case may be; or

                 (ii)   Such Selling Stockholder has not complied with any
           obligation or satisfied any condition that is required to be
           performed or satisfied on the part of such Selling Stockholder at or
           prior to the Closing Date or any later date on which Option Shares
           are to be purchased, as the case may be.

           (j)   The Company shall have obtained and delivered to you an
      agreement from each officer and director of the Company, each Selling
      Stockholder and each other beneficial owner of Common Stock in writing
      prior to the date hereof that such person will not, during the Lock-up
      Period, effect the Disposition of any Securities now owned or hereafter
      acquired directly by such person or with respect to which such person has
      or hereafter acquires the power of disposition, otherwise than (i) as a
      bona fide gift or gifts, provided the donee or donees thereof agree in
      writing to be bound by this restriction, (ii) as a distribution to
      limited partners, members or stockholders of such person, provided the
      distributees thereof agree in writing to be bound by the terms of this
      restriction or (iii) with the prior written consent of BancAmerica
      Robertson Stephens.  The foregoing restriction shall have been expressly
      agreed to preclude the holder of the Securities from engaging in any
      hedging or other transaction that is designed to or reasonably expected
      to lead to or result in a Disposition of Securities during the Lock-up
      Period, even if such Securities would be disposed of by someone other
      than the such holder.  Such prohibited hedging or other transactions
      would include any short sale (whether or not against the box) or any
      purchase, sale or grant of any right (including any put or call option)
      with respect to any Securities or with respect to any security (other
      than a broad-based market basket or index) that includes, relates to or
      derives any significant part of its value from the Securities.
      Notwithstanding the foregoing, this restriction shall not prohibit (i)
      the sale of Shares to the Underwriters pursuant to this Agreement or (ii)
      resales of shares of Common Stock acquired either in the public offering
      to which the Registration Statement relates or in subsequent open-market
      purchases.  Furthermore, such person will have also agreed and consented
      to the entry of stop transfer instructions with the Company's transfer
      agent against the transfer of the Securities held by such person except
      in compliance with this restriction.

           (k)   The Company and the Selling Stockholders shall have furnished
      to you such further certificates and documents as you shall reasonably
      request (including certificates of officers of the Company, the Selling
      Stockholders or officers of the Selling Stockholders (when the Selling
      Stockholder is not a natural person) as to the accuracy of the
      representations and warranties of the Company and the Selling
      Stockholders herein, as to the performance by the Company and the Selling
      Stockholders of their respective obligations hereunder and as to the
      other conditions concurrent and precedent to the obligations of the
      Underwriters hereunder.

           All such opinions, certificates, letters and documents will be in
compliance with the provisions hereof only if they are reasonably satisfactory
to Underwriters' Counsel.  The Company and the Selling Stockholders will
furnish you with such number of conformed copies of such opinions,
certificates, letters and documents as you shall reasonably request.

      7.   Option Shares.

           (a)   On the basis of the representations, warranties and agreements
      herein contained, but subject to the terms and conditions herein set
      forth, the Company and the Selling Stockholders named in Schedule C
      hereto (the "Option Stockholders") hereby grant, severally and not
      jointly, to the several





                                       25
<PAGE>   26
      Underwriters, for the purpose of covering over-allotments in connection
      with the distribution and sale of the Firm Shares only, nontransferable
      options to purchase the respective number of Option Shares as set forth
      opposite the names of the Company and the Option Stockholders in Schedule
      C hereto, all at the purchase price per share for the Firm Shares set
      forth in Section 3 hereof.  Such option may be exercised by the
      Representatives on behalf of the several Underwriters on one or more
      occasions in whole or in part during the period of thirty days after the
      date on which the Firm Shares are initially offered to the public, by
      giving written notice to the Company and the Option Stockholders in
      accordance with Section 12 hereof.  The number of Option Shares to be
      purchased by each Underwriter upon the exercise of such option shall be
      the same proportion of the total number of Option Shares to be purchased
      by the several Underwriters pursuant to the exercise of such option as
      the number of Firm Shares purchased by such Underwriter (set forth in
      Schedule A hereto) bears to the total number of Firm Shares purchased by
      the several Underwriters (set forth in Schedule A hereto), adjusted by
      the Representatives in such manner as to avoid fractional shares.  In the
      event such option is exercised for less than all of the Option Shares,
      the Option Shares to be purchased shall be purchased [let us know if this
      will be pro rata (based on the numbers of Option Shares set forth in
      Schedule C hereto) from the Company and each of the Option Stockholders,
      or whether there will be a priority (e.g., Option Stockholders first, on
      a pro rata basis, and then Company)], adjusted by the Representatives in
      such manner as to avoid fractional shares.

                 The certificates in negotiable form for the Option Shares to
      be purchased from the Option Stockholders pursuant to the exercise of the
      option granted by this Section 7 have been placed in custody (for
      delivery under this Agreement) under the Custody Agreement.  Each Option
      Stockholder agrees that the certificates for the Option Shares of such
      Option Stockholder so held in custody are subject to the interests of the
      Underwriters hereunder, that the arrangements made by such Option
      Stockholder for such custody, including the Power of Attorney is to that
      extent irrevocable and that the obligations of such Option Stockholder
      hereunder shall not be terminated by the act of such Option Stockholder
      or by operation of law, whether by the death or incapacity of such Option
      Stockholder or the occurrence of any other event, except as specifically
      provided herein or in the Custody Agreement.  If any Option Stockholder
      should die or be incapacitated, or if any other such event should occur,
      before the delivery of the certificates for the Option Shares to be sold
      by such Option Stockholder, such Option Shares shall, except as
      specifically provided herein or in the Custody Agreement, be delivered by
      the Custodian in accordance with the terms and conditions of this
      Agreement as if such death, incapacity or other event had not occurred,
      regardless of whether the Custodian shall have received notice of such
      death or other event.

                 Delivery of definitive certificates for the Option Shares to
      be purchased by the several Underwriters pursuant to the exercise of the
      option granted by this Section 7 shall be made against payment of the
      purchase price therefor by the several Underwriters by certified or
      official bank check or checks drawn in next-day funds, payable to the
      order of the Company with regard to the Option Shares being purchased
      from the Company, and to the order of the Custodian for the respective
      accounts of Option Stockholders with regard to the Option Shares being
      purchased from the Option Stockholders (and the Company and the Option
      Stockholders agree not to deposit and to cause the Custodian not to
      deposit any such check in the bank on which it is drawn, and not to take
      any other action with the purpose or effect of receiving immediately
      available funds, until the business day following the date of its
      delivery to the Company or the Custodian, as the case may be).  In the
      event of any breach of the foregoing, the Company and the Option
      Stockholders, as the case may be, shall reimburse the Underwriters for
      the interest lost and any other expenses borne by them by reason of such
      breach.  Such delivery and payment shall take place at the offices of
      Brobeck Phleger & Harrison LLP, 1125 Seventeenth Street, Suite 2525,
      Denver, Colorado or at such other place as may be agreed upon





                                       26
<PAGE>   27
      among the Representatives, the Company and the Attorneys (i) on the
      Closing Date, if written notice of the exercise of such option is
      received by the Company and the Option Stockholders at least two full
      business days prior to the Closing Date, or (ii) on a date that shall not
      be later than the third full business day following the date the Company
      and the Option Stockholders receive written notice of the exercise of
      such option, if such notice is received by the Company and the Option
      Stockholders less than two full business days prior to the Closing Date.

                 The certificates for the Option Shares to be so delivered will
      be made available to you at such office or such other location, including
      in New York City, as you may reasonably request for checking at least one
      full business day prior to the date of payment and delivery and will be
      in such names and denominations as you may request, such request to be
      made at least two full business days prior to such date of payment and
      delivery.  If the Representatives so elect, delivery of the Option Shares
      may be made by credit through full fast transfer to the accounts at The
      Depository Trust Company designated by the Representatives.

                 It is understood that you, individually, and not as the
      Representatives of the several Underwriters, may (but shall not be
      obligated to) make payment of the purchase price on behalf of any
      Underwriter or Underwriters whose check or checks shall not have been
      received by you prior to the date of payment and delivery for the Option
      Shares to be purchased by such Underwriter or Underwriters.  Any such
      payment by you shall not relieve any such Underwriter or Underwriters of
      any of its or their obligations hereunder.

           (b)   Upon exercise of any option provided for in Section 7(a)
      hereof, the obligations of the several Underwriters to purchase such
      Option Shares will be subject (as of the date hereof and as of the date
      of payment and delivery for such Option Shares) to the accuracy of and
      compliance with the representations, warranties and agreements of the
      Company and the Option Stockholders herein, to the accuracy of the
      statements of the Company, the Option Stockholders and officers of the
      Company made pursuant to the provisions hereof, to the performance by the
      Company and the Option Stockholders of their respective obligations
      hereunder, to the conditions set forth in Section 6 hereof, and to the
      condition that all proceedings taken at or prior to the payment date in
      connection with the sale and transfer of such Option Shares shall be
      satisfactory in form and substance to you and to Underwriters' Counsel,
      and you shall have been furnished with all such documents, certificates
      and opinions as you may request in order to evidence the accuracy and
      completeness of any of the representations, warranties or statements, the
      performance of any of the covenants or agreements of the Company and the
      Option Stockholders or the satisfaction of any of the conditions herein
      contained.

      8.   Indemnification and Contribution.

           (a)   The Company agrees to indemnify and hold harmless each
      Underwriter against any losses, claims, damages or liabilities, joint or
      several, to which such Underwriter may become subject (including in its
      capacity as an Underwriter or as a "qualified independent underwriter"
      within the meaning of Schedule E of the Bylaws of the NASD), under the
      Act, the Exchange Act or otherwise, specifically including losses,
      claims, damages or liabilities (or actions in respect thereof) arising
      out of or based upon (i) any breach of any representation, warranty,
      agreement or covenant of the Company herein contained, (ii) any untrue
      statement or alleged untrue statement of any material fact contained in
      the Registration Statement or any amendment or supplement thereto, or the
      omission or alleged omission to state therein a material fact required to
      be stated therein or necessary to make the statements therein not
      misleading or (iii) any untrue statement or alleged untrue statement of
      any material fact contained in any Preliminary Prospectus or the
      Prospectus or any amendment or





                                       27
<PAGE>   28
      supplement thereto, or the omission or alleged omission to state therein
      a material fact required to be stated therein or necessary to make the
      statements therein, in the light of the circumstances under which they
      were made, not misleading, and agrees to reimburse each Underwriter for
      any legal or other expenses reasonably incurred by it in connection with
      investigating or defending any such loss, claim, damage, liability or
      action; provided, however, that the Company shall not be liable in any
      such case to the extent that any such loss, claim, damage, liability or
      action arises out of or is based upon an untrue statement or alleged
      untrue statement or omission or alleged omission made in the Registration
      Statement, such Preliminary Prospectus or the Prospectus, or any such
      amendment or supplement thereto, in reliance upon, and in conformity
      with, written information relating to any Underwriter furnished to the
      Company by such Underwriter, directly or through you, specifically for
      use in the preparation thereof and, provided further that the indemnity
      agreement provided in this Section 8(a) with respect to any Preliminary
      Prospectus shall not inure to the benefit of any Underwriter from whom
      the person asserting any losses, claims, damages, liabilities or actions
      based upon any untrue statement or alleged untrue statement of material
      fact or omission or alleged omission to state therein a material fact
      purchased Shares, if a copy of the Prospectus in which such untrue
      statement or alleged untrue statement or omission or alleged omission was
      corrected had not been sent or given to such person within the time
      required by the Act and the Rules and Regulations, unless such failure is
      the result of noncompliance by the Company with Section 4(d) hereof.

                 The indemnity agreement in this Section 8(a) shall extend upon
      the same terms and conditions to, and shall inure to the benefit of, each
      person, if any, who controls any Underwriter within the meaning of the
      Act or the Exchange Act.  This indemnity agreement shall be in addition
      to any liabilities that the Company may otherwise have.

           (b)   Each Selling Stockholder, severally and not jointly, agrees to
      indemnify and hold harmless each Underwriter against any losses, claims,
      damages or liabilities, joint or several, to which such Underwriter may
      become subject (including in its capacity as an Underwriter) under the
      Act, the Exchange Act or otherwise, specifically including losses,
      claims, damages or liabilities (or actions in respect thereof) arising
      out of or based upon (i) any breach of any representation, warranty,
      agreement or covenant of such Selling Stockholder herein contained, (ii)
      any untrue statement or alleged untrue statement of any material fact
      contained in the Registration Statement or any amendment or supplement
      thereto, or the omission or alleged omission to state therein a material
      fact required to be stated therein or necessary to make the statements
      therein not misleading, or (iii) any untrue statement or alleged untrue
      statement of any material fact contained in any Preliminary Prospectus or
      the Prospectus or any amendment or supplement thereto, or the omission or
      alleged omission to state therein a material fact necessary to make the
      statements therein, in the light of the circumstances under which they
      were made, not misleading, in the case of subparagraphs (ii) and (iii) of
      this Section 8(b) to the extent, but only to the extent, that such untrue
      statement or alleged untrue statement or omission or alleged omission was
      made in reliance upon and in conformity with written information
      furnished to the Company or such Underwriter by such Selling Stockholder,
      directly or through such Selling Stockholder's representatives,
      specifically for use in the preparation thereof, and agrees to reimburse
      each Underwriter for any legal or other expenses reasonably incurred by
      it in connection with investigating or defending any such loss, claim,
      damage, liability or action; provided, however, that the indemnity
      agreement provided in this Section 8(b) with respect to any Preliminary
      Prospectus shall not inure to the benefit of any Underwriter from whom
      the person asserting any losses, claims, damages, liabilities or actions
      based upon any untrue statement or alleged untrue statement of a material
      fact or omission or alleged omission to state therein a material fact
      purchased Shares, if a copy of the Prospectus in which such untrue
      statement or alleged untrue statement or omission or alleged omission was
      corrected had not been sent or given to such person within the time
      required by the Act and the Rules and Regulations, unless such failure is
      the result of noncompliance by the Company with Section 4(d) hereof.





                                       28
<PAGE>   29
                 The indemnity agreement in this Section 8(b) shall extend upon
      the same terms and conditions to, and shall inure to the benefit of, each
      person, if any, who controls any Underwriter within the meaning of the
      Act or the Exchange Act.  This indemnity agreement shall be in addition
      to any liabilities that such Selling Stockholder otherwise may have.

           (c)   Each Underwriter, severally and not jointly, agrees to
      indemnify and hold harmless the Company and each Selling Stockholder
      against any losses, claims, damages or liabilities, joint or several, to
      which the Company or such Selling Stockholder may become subject under
      the Act or otherwise, specifically including losses, claims, damages or
      liabilities (or actions in respect thereof) arising out of or based upon
      (i) any breach of any representation, warranty, agreement or covenant of
      such Underwriter herein contained, (ii) any untrue statement or alleged
      untrue statement of any material fact contained in the Registration
      Statement or any amendment or supplement thereto, or the omission or
      alleged omission to state therein a material fact required to be stated
      therein or necessary to make the statements therein not misleading or
      (iii) any untrue statement or alleged untrue statement of any material
      fact contained in any Preliminary Prospectus or the Prospectus or any
      amendment or supplement thereto, or the omission or alleged omission to
      state therein a material fact necessary to make the statements therein,
      in the light of the circumstances under which they were made, not
      misleading, in the case of subparagraphs (ii) and (iii) of this Section
      8(c) to the extent, but only to the extent, that such untrue statement or
      alleged untrue statement or omission or alleged omission was made in
      reliance upon and in conformity with written information furnished to the
      Company by such Underwriter, directly or through you, specifically for
      use in the preparation thereof, and agrees to reimburse the Company and
      each such Selling Stockholder for any legal or other expenses reasonably
      incurred by the Company and each such Selling Stockholder in connection
      with investigating or defending any such loss, claim, damage, liability
      or action.

                 The indemnity agreement in this Section 8(c) shall extend upon
      the same terms and conditions to, and shall inure to the benefit of, each
      officer of the Company who signed the Registration Statement and each
      director of the Company, each Selling Stockholder and each person, if
      any, who controls the Company or any Selling Stockholder within the
      meaning of the Act or the Exchange Act.  This indemnity agreement shall
      be in addition to any liabilities that each Underwriter may otherwise
      have.

           (d)   Promptly after receipt by an indemnified party under this
      Section 8 of notice of the commencement of any action, such indemnified
      party shall, if a claim in respect thereof is to be made against any
      indemnifying party under this Section 8, notify the indemnifying party in
      writing of the commencement thereof but the omission so to notify the
      indemnifying party will not relieve it from any liability that it may
      have to any indemnified party otherwise than under this Section 8.  In
      case any such action is brought against any indemnified party, and it
      notified the indemnifying party of the commencement thereof, the
      indemnifying party will be entitled to participate therein and, to the
      extent that it shall elect by written notice delivered to the indemnified
      party promptly after receiving the aforesaid notice from such indemnified
      party, to assume the defense thereof, with counsel reasonably
      satisfactory to such indemnified party; provided, however, that if the
      defendants in any such action include both the indemnified party and the
      indemnifying party and the indemnified party shall have reasonably
      concluded that there may be legal defenses available to it and/or other
      indemnified parties that are different from or additional to those
      available to the indemnifying party, the indemnified party or parties
      shall have the right to select separate counsel to assume such legal
      defenses and to otherwise





                                       29
<PAGE>   30
      participate in the defense of such action on behalf of such indemnified
      party or parties.  Upon receipt of notice from the indemnifying party to
      such indemnified party of the indemnifying party's election so to assume
      the defense of such action and approval by the indemnified party of
      counsel, the indemnifying party will not be liable to such indemnified
      party under this Section 8 for any legal or other expenses subsequently
      incurred by such indemnified party in connection with the defense thereof
      unless (i) the indemnified party shall have employed separate counsel in
      accordance with the proviso to the next preceding sentence (it being
      understood, however, that the indemnifying party shall not be liable for
      the expenses of more than one separate counsel (together with appropriate
      local counsel) approved by the indemnifying party representing all the
      indemnified parties under Section 8(a), 8(b) or 8(c) hereof who are
      parties to such action), (ii) the indemnifying party shall not have
      employed counsel satisfactory to the indemnified party to represent the
      indemnified party within a reasonable time after notice of commencement
      of the action or (iii) the indemnifying party has authorized the
      employment of counsel for the indemnified party at the expense of the
      indemnifying party.  In no event shall any indemnifying party be liable
      in respect of any amounts paid in settlement of any action unless the
      indemnifying party shall have approved the terms of such settlement;
      provided that such consent shall not be unreasonably withheld.  No
      indemnifying party shall, without the prior written consent of the
      indemnified party, effect any settlement of any pending or threatened
      proceeding in respect of which any indemnified party is or could have
      been a party and indemnification could have been sought hereunder by such
      indemnified party, unless such settlement includes an unconditional
      release of such indemnified party from all liability on all claims that
      are the subject matter of such proceeding.

           (e)   In order to provide for just and equitable contribution in any
      action in which a claim for indemnification is made pursuant to this
      Section 8 but it is judicially determined (by the entry of a final
      judgment or decree by a court of competent jurisdiction and the
      expiration of time to appeal or the denial of the last right of appeal)
      that such indemnification may not be enforced in such case
      notwithstanding the fact that this Section 8 provides for indemnification
      in such case, all the parties hereto shall contribute to the aggregate
      losses, claims, damages or liabilities to which they may be subject
      (after contribution from others) in such proportion so that, except as
      set forth in Section 8(f) hereof, the Underwriters severally and not
      jointly are responsible pro rata for the portion represented by the
      percentage that the underwriting discount bears to the initial public
      offering price, and the Company and the Selling Stockholders are
      responsible for the remaining portion, provided, however, that (i) no
      Underwriter shall be required to contribute any amount in excess of the
      amount by which the underwriting discount applicable to the Shares
      purchased by such Underwriter exceeds the amount of damages that such
      Underwriter has otherwise required to pay and (ii) no person guilty of a
      fraudulent misrepresentation (within the meaning of Section 11(f) of the
      Act) shall be entitled to contribution from any person who is not guilty
      of such fraudulent misrepresentation.  The contribution agreement in this
      Section 8(e) shall extend upon the same terms and conditions to, and
      shall inure to the benefit of, each person, if any, who controls any
      Underwriter, the Company or any Selling Stockholder within the meaning of
      the Act or the Exchange Act and each officer of the Company who signed
      the Registration Statement and each director of the Company.

           (f)   The liability of each Selling Stockholder under the
      representations, warranties and agreements contained herein and under the
      indemnity and contribution agreements contained in the provisions of this
      Section 8 shall be limited to an amount equal to the initial public
      offering price of the Selling Stockholder Shares and any Option Shares
      sold by such Selling Stockholder to the Underwriters minus the amount of
      the underwriting discount paid thereon to the Underwriters by such
      Selling Stockholder.  The Company and such Selling Stockholders may
      agree, as among themselves and without limiting the rights of the
      Underwriters under this Agreement, as to the respective amounts of such
      liability for which they each shall be responsible.

           (g)   The parties to this Agreement hereby acknowledge that they are
      sophisticated business persons who were represented by counsel during the
      negotiations regarding the provisions hereof including the provisions of
      this Section 8, and are fully informed regarding said provisions.  They
      further acknowledge that the provisions of this Section 8 fairly allocate
      the risks in light of the ability of the parties to investigate the
      Company and its business in order to assure that adequate disclosure is
      made in the Registration Statement and Prospectus as required by the Act
      and the Exchange Act.

      9.   Representations, Warranties, Covenants and Agreements to Survive
Delivery.  All representations, warranties, covenants and agreements of the
Company, the Selling Stockholders and the Underwriters herein or in
certificates delivered pursuant hereto, and the indemnity and contribution
agreements contained in Section 8 hereof shall remain operative and in full
force and effect regardless of any investigation made by or on behalf of any
Underwriter or any person controlling any Underwriter within the meaning of the
Act or the Exchange Act, or by or on behalf of the Company or any Selling
Stockholder, or any of their officers, directors or controlling persons within
the meaning of the Act or the Exchange Act, and shall survive the delivery of
the Shares to the several Underwriters hereunder or termination of this
Agreement.

      10.  Substitution of Underwriters.  If any Underwriter or Underwriters
shall fail to take up and pay for the number of Firm Shares agreed by such
Underwriter or Underwriters to be purchased hereunder upon tender of such Firm
Shares in accordance with the terms hereof, and if the aggregate number of Firm
Shares that such defaulting Underwriter or Underwriters so agreed but failed to
purchase does not exceed ten percent of the Firm Shares, the remaining
Underwriters shall be obligated, severally in proportion to their respective
commitments hereunder, to take up and pay for the Firm Shares of such
defaulting Underwriter or Underwriters.

           If any Underwriter or Underwriters so defaults and the aggregate
number of Firm Shares that such defaulting Underwriter or Underwriters agreed
but failed to take up and pay for exceeds ten percent of the Firm Shares, the
remaining Underwriters shall have the right, but shall not be obligated, to take
up and pay for (in such proportions as may be agreed upon among them) the Firm
Shares that the defaulting Underwriter or Underwriters so agreed but failed to
purchase.  If such remaining Underwriters do not, at the Closing Date, take up
and pay for the Firm Shares that the defaulting Underwriter or Underwriters so
agreed but failed to purchase, the Closing Date shall be postponed for
twenty-four hours to allow the several Underwriters the privilege of
substituting within twenty-four hours (including non-business hours) another
underwriter or underwriters (which may include any nondefaulting Underwriter)
satisfactory to the Company.  If no such underwriter or underwriters shall have
been substituted as aforesaid by such postponed Closing Date, the Closing Date
may, at the option of the Company, be postponed for a further twenty-four hours,
if necessary, to allow the Company the privilege of finding another underwriter
or underwriters, satisfactory to you, to purchase the Firm Shares that the
defaulting Underwriter or Underwriters so agreed but failed to purchase.  If it
shall be arranged for the remaining Underwriters or substituted underwriter or
underwriters to take up the Firm Shares of the defaulting Underwriter or
Underwriters as provided in this Section 10, (i) the Company shall have the
right to postpone the time of delivery for a period of not more than seven full
business days, in order to effect whatever changes may thereby be made necessary
in the Registration Statement or the Prospectus, or in any other documents or
arrangements, and the Company agrees promptly to file any amendments to the
Registration Statement, supplements to the Prospectus or other such documents
that may thereby be made necessary, and (ii) the respective number of Firm
Shares to be purchased by the remaining Underwriters and substituted underwriter
or underwriters shall be taken as the basis of their underwriting obligation.
If the remaining Underwriters shall not take up and pay for all such Firm Shares
so agreed to be purchased by the defaulting Underwriter or Underwriters or
substitute another underwriter or underwriters as aforesaid and the Company
shall not find or shall not elect to seek another underwriter or underwriters
for such Firm Shares as aforesaid, then this Agreement shall terminate.

           In the event of any termination of this Agreement pursuant to the
preceding paragraph of this Section 10, neither the Company nor any Selling
Stockholder shall be liable to any Underwriter (except as provided in Sections
5 and 8 hereof) nor shall any Underwriter (other than an Underwriter who shall
have failed, otherwise than for some reason permitted under this Agreement, to
purchase the number of Firm Shares agreed by such Underwriter to be purchased
hereunder, which Underwriter shall remain liable to the Company, the Selling
Stockholders and the other Underwriters for damages, if any, resulting from
such default) be liable to the Company or any Selling Stockholder (except to
the extent provided in Sections 5 and 8 hereof).

           The term "Underwriter" in this Agreement shall include any person
substituted for an Underwriter under this Section 10.

      11.  Effective Date of this Agreement and Termination.

           (a)   This Agreement shall become effective at the earlier of (i)
      6:30 A.M., San Francisco time, on the first full business day following
      the effective date of the Registration Statement or (ii) the time of the
      initial public offering of any of the Shares by the Underwriters after
      the Registration Statement becomes effective.  The time of the initial
      public offering shall mean the time of the release by you, for
      publication, of the first newspaper advertisement relating to the Shares,
      or the time at which the Shares are first generally offered by the
      Underwriters to the public by letter, telephone, telegram or telecopy,
      whichever shall first occur.  By giving notice as set forth in Section 12
      before the time this Agreement becomes effective, you, as Representatives
      of the several Underwriters, or the Company, may prevent this Agreement
      from becoming effective without liability of any party to any other
      party, except as provided in Sections 4(j), 5 and 8 hereof.

           (b)   You, as Representatives of the several Underwriters, shall
      have the right to terminate this Agreement by giving notice as
      hereinafter specified at any time on or prior to the Closing Date or on
      or prior to any later date on which Option Shares are to be purchased, as
      the case may be, (i) if the Company or any Selling Stockholder shall have
      failed, refused or been unable to perform any agreement on its part to be
      performed, or because any other condition of the Underwriters'
      obligations hereunder required to be fulfilled is not fulfilled,
      including any change in the condition (financial or otherwise), earnings,
      operations, business or business prospects of the Company from that set
      forth in the Registration Statement or Prospectus that, in your sole
      judgment, is material and adverse, or (ii) if additional material
      governmental restrictions, not in force and effect on the date hereof,
      shall have been imposed upon trading in securities generally or minimum
      or maximum prices shall have been generally established on the New York
      Stock Exchange or on the American Stock Exchange or in the
      over-the-counter market by the NASD, or trading in securities generally
      shall have been suspended on either such exchange or in the
      over-the-counter market by the NASD, or if a banking moratorium shall
      have been declared by federal, New York or California authorities, or
      (iii) if the Company shall have sustained a loss by strike, fire, flood,
      earthquake, accident or other calamity of such character as to interfere
      materially with the conduct of the business and operations of the Company
      regardless of whether or not such loss shall have been insured or (iv) if
      there shall have been a material adverse change in the general political
      or economic conditions or financial markets as in your reasonable
      judgment makes it inadvisable or impracticable to proceed with the
      offering, sale and delivery of the Shares, or (v) if there shall have
      been an outbreak or escalation of hostilities or of any other
      insurrection or armed conflict or the declaration by the United States of
      a national emergency that, in the reasonable opinion of the
      Representatives, makes it impracticable or inadvisable to proceed with
      the public offering of the Shares as contemplated by the Prospectus.  In
      the event of termination pursuant to subparagraph (i) above, the Company
      shall remain obligated to pay costs and expenses





                                       32
<PAGE>   33
      pursuant to Sections 4(j), 5 and 8 hereof.  Any termination pursuant to
      any of subparagraphs (ii) through (v) above shall be without liability of
      any party to any other party except as provided in Sections 5 and 8
      hereof.

                 If you elect to prevent this Agreement from becoming effective
      or to terminate this Agreement as provided in this Section 11, you shall
      promptly notify the Company by telephone, telecopy or telegram, in each
      case confirmed by letter.  If the Company shall elect to prevent this
      Agreement from becoming effective, the Company shall promptly notify you
      by telephone, telecopy or telegram, in each case, confirmed by letter.

of at least a majority of the outstanding shares in accordance with Section 228
thereof, and written notice having been given in accordance with the

shares of Preferred Stock shall be undesignated as to series.

         2.      Issuance of Preferred Stock.  The Preferred Stock may be
issued from time to time in one or more series.  The Board of Directors is
hereby authorized, by filing one or more certificates pursuant to the Delaware
General Corporation Law (each, a "Preferred Stock Designation"), to fix or
alter from time to time the designations, powers, preferences and rights of
each such series of Preferred Stock and the qualifications, limitations or
restrictions thereof, including without limitation the dividend rights,
dividend rate, conversion rights, voting rights, rights and terms of redemption
(including sinking fund provisions), redemption price or prices, and the
liquidation preferences of any wholly-unissued series of Preferred Stock, and
to establish from time to time the number of shares constituting any such
series and the designation thereof, or any of them; and to increase or decrease
the number of shares of any series subsequent to the issuance of shares of that
series, but not below the number of shares of such series then outstanding.  In
case the number of shares of any series shall be decreased in accordance with
the foregoing sentence, the shares constituting such decrease shall resume the
status that they had prior to the adoption of the resolution originally fixing
the number of shares of such series.

         3.      Rights, Preferences, Privileges and Restrictions of Common
Stock.
                 (a)      Dividend Rights.  Subject to the prior or equal
rights of holders of all classes of stock at the time outstanding having prior
or equal rights as to dividends, the holders of the Common Stock shall be
entitled to receive, when and as declared by the Board of Directors, out of any
assets of the corporation legally available therefor, such dividends as may be
declared from time to time by the Board of Directors.

                 (b)      Redemption.  The Common Stock is not redeemable upon
demand of any holder thereof or upon demand of this corporation.

                 (c)      Voting Rights.  The holder of each share of Common
Stock shall have the right to one vote, and shall be entitled to notice of any
stockholders' meeting in accordance with





                                     - 2 -

the Bylaws of this corporation, and shall be entitled to vote upon such matters
and in such manner as may be provided by law.

                                   ARTICLE V

         1.      Exculpation.  A director of the corporation shall not be
personally liable to the corporation or its stockholders 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 corporation or its
stockholders, (ii) for acts or omissions not in good faith or which 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.  If the Delaware General
Corporation Law is hereafter amended to further reduce or to authorize, with
the approval of the corporation's stockholders, further reductions in the
liability of the corporation's directors for breach of fiduciary duty, then a
director of the corporation shall not be liable for any such breach to the
fullest extent permitted by the Delaware General Corporation Law as so amended.

         2.      Indemnification.  To the extent permitted by applicable law,
this corporation is also authorized to provide indemnification of (and
advancement of expenses to) such agents (and any other persons to which
Delaware law permits this corporation to provide indemnification) through bylaw
provisions, agreements with such agents or other persons, vote of stockholders
or disinterested directors or otherwise, in excess of the indemnification and
advancement otherwise permitted by Section 145 of the Delaware General
Corporation Law, subject only to limits created by applicable Delaware law
(statutory or non-statutory), with respect to actions for breach of duty to the
corporation, its stockholders, and others.

         3.      Effect of Repeal or Modification.  Any repeal or modification
of any of the foregoing provisions of this Article V shall be prospective and
shall not adversely affect any right or protection of a director, officer,
agent or other person existing at the time of, or increase the liability of any
director of the corporation with respect to any acts or omissions of such
director occurring prior to, such repeal or modification.

                                   ARTICLE VI

         Elections of directors need not be by written ballot except and to the

authorized, or any warrants, options, bonds, debentures or other securities
convertible into,

series thereof, of stock; but such additional shares of stock and such
warrants, options, bonds, debentures or other securities convertible into,
exchangeable for or carrying any right to purchase any shares of any class, or
series thereof, of stock may be issued or disposed of by the Board of Directors
to such persons, and on such terms and for such lawful consideration as in its
discretion it shall deem advisable or as the corporation shall have by contract
agreed.

                                  ARTICLE VIII

         The corporation is to have a perpetual existence.

                                   ARTICLE IX

any provision contained in this Amended and Restated Certificate of
Incorporation and/or any provision contained in any amendment to or restatement
of this Amended and Restated Certificate of Incorporation, in the manner now or
hereafter prescribed by statute, and all rights conferred on stockholders
herein are granted subject to this reservation.

                                   ARTICLE X

         The Board of Directors may from time to time make, amend, supplement

forth in the Bylaws; provided, however, that the stockholders may change or
repeal any bylaw adopted by the Board of Directors by the requisite affirmative
vote of stockholders as set forth in the Bylaws; and, provided further, that no
amendment or supplement to the Bylaws adopted by the Board of Directors shall
vary or conflict with any amendment or supplement thus adopted by the

                            SCC COMMUNICATIONS CORP.


                                   ARTICLE I

may require.

                                   ARTICLE II
                            MEETINGS OF STOCKHOLDERS

         Section 1.       Place of Meetings.  All meetings of the stockholders
for the election of Directors shall be held in the City of Boulder, State of
Colorado, at such place as may be fixed from time to time by the Board of
Directors, or at such other place either within or without the State of
Colorado as shall be designated from time to time by the Board of Directors and
stated in the notice of the meeting.  Meetings of stockholders for any other
purpose may be held at such time and place, within or without the State of
Colorado, as shall be stated in the notice of the meeting or in a duly executed
waiver of notice thereof.

         Section 2.       Annual Meeting.

                          (a)     The annual meeting of the stockholders of the
corporation, for the purpose of election of Directors and for such other
business as may lawfully come before it, shall be held on such date and at such
time as may be designated from time to time by the Board of Directors.

                          (b)     At an annual meeting of the stockholders,
only such business shall be conducted as shall have been properly brought
before the meeting.  To be properly brought before an annual meeting, business
must be: (A) specified in the notice of meeting (or any supplement thereto)
given by or at the direction of the Board of Directors, (B) otherwise properly
brought before the meeting by or at the direction of the Board of Directors, or
(C) otherwise properly brought before the meeting by a stockholder.  For
business to be properly brought before an annual meeting by a stockholder, the
stockholder must have given timely notice thereof in writing to the Secretary
of the corporation.  To be timely, a stockholder's notice must be delivered to
or mailed and received at the principal executive offices of the corporation no
later than the date specified in the corporation's proxy statement released to
stockholders in connection





<PAGE>   2
with the previous year's annual meeting of stockholders, which date shall be
not less than one hundred twenty (120) calendar days in advance of the date of
such proxy statement; provided, however, that in the event that no annual
meeting was held in the previous year or the date of the annual meeting has
been changed by more than thirty (30) days from the date contemplated at the
time of the previous year's proxy statement, notice by the stockholder to be
timely must be so received a reasonable time before the solicitation is made.
A stockholder's notice to the Secretary shall set forth as to each matter the
stockholder proposes to bring before the annual meeting:  (i) a brief
description of the business desired to be brought before the annual meeting and
the reasons for conducting such business at the annual meeting, (ii) the name
and address, as they appear on the corporation's books, of the stockholder
proposing such business, (iii) the class and number of shares of the
corporation which are beneficially owned by the stockholder, (iv) any material
interest of the stockholder in such business and (v) any other information that
is required to be provided by the stockholder pursuant to Regulation 14A under
the Securities Exchange Act of 1934, as amended (the "1934 Act"), in his or her
capacity as a proponent to a stockholder proposal.  In addition to the
foregoing, in order to include information with respect to a stockholder
proposal in the proxy statement and form of proxy for a stockholder's meeting,
stockholders must provide notice as required by the regulations promulgated
under the 1934 Act to the extent such regulations require notice that is
different from the notice required above.  Notwithstanding anything in these
Bylaws to the contrary, no business shall be conducted at any annual meeting
except in accordance with the procedures set forth in this paragraph (b) of
this Section 2.  The chairperson of the annual meeting shall, if the facts
warrant, determine and declare at the meeting that business was not properly
brought before the meeting and in accordance with the provisions of this
paragraph (b), and, if the chairperson should so determine, the chairperson
shall so declare at the meeting that any such business not properly brought
before the meeting shall not be transacted.

                          (c)     Only persons who are nominated in accordance
with the procedures set forth in this paragraph (c) shall be eligible for
election as Directors.  Nominations of persons for election to the Board of
Directors of the corporation may be made at a meeting of stockholders by or at
the direction of the Board of Directors or by any stockholder of the
corporation entitled to vote in the election of Directors at the meeting who
complies with the notice procedures set forth in this paragraph (c).  Such
nominations, other than those made by or at the direction of the Board of
Directors, shall be made pursuant to timely notice in writing to the Secretary
of the corporation in accordance with the provisions of paragraph (b) of this
Section 2.  Such stockholder's notice shall set forth (i) as to each person, if
any, whom the stockholder proposes to nominate for election or re-election as a
Director:  (A) the name, age, business address and residence address of such
person, (B) the principal occupation or employment of such person, (C) the
class and number of shares of the corporation that are beneficially owned by
such person, (D) a description of all arrangements or understandings between
the stockholder and each nominee and any other person or persons (naming such
person or persons) pursuant to which the nominations are to be made by the
stockholder, and (E) any other information relating to such person that is
required to be disclosed in solicitations of proxies for election of Directors,
or is otherwise required, in each case pursuant to Regulation 14A under





                                       2.
<PAGE>   3
the 1934 Act (including without limitation such person's written consent to
being named in the proxy statement, if any, as a nominee and to serving as a
Director if elected); and (ii) as to such stockholder giving notice, the
information required to be provided pursuant to subitems (ii), (iii) and (iv)
of paragraph (b) of this Section 2.  At the request of the Board of Directors,
any person nominated by a stockholder for election as a Director shall furnish
to the Secretary of the corporation that information required to be set forth
in the stockholder's notice of nomination which pertains to the nominee.  No
person shall be eligible for election as a Director of the corporation unless
nominated in accordance with the procedures set forth in this paragraph (c).
The chairperson of the meeting shall, if the facts warrant, determine and
declare at the meeting that a nomination was not made in accordance with the
procedures prescribed by these Bylaws, and if the chairperson should so
determine, the chairperson shall so declare at the meeting, and the defective
nomination shall be disregarded.

         Section 3.       Notice of Annual Meeting.  Written notice of the
annual meeting stating the place, date and hour of the meeting shall be given
to each stockholder entitled to vote at such meeting not less than ten (10) nor
more than sixty (60) days before the date of the meeting.

         Section 4.       Voting List.  The officer who has charge of the stock
ledger of the corporation shall prepare and make, or have prepared and made, at
least ten (10) days before every meeting of stockholders, a complete list of
the stockholders entitled to vote at the meeting, arranged in alphabetical
order, and showing the address of each stockholder and the number of shares
registered in the name of each stockholder.  Such list shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten (10) days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held.  The list shall also
be produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

         Section 5.       Special Meetings.  Special meetings of the
stockholders, for any purpose or purposes, unless otherwise prescribed by
statute or by the Certificate of Incorporation, as amended from time to time,
may only be called as provided in this Section 5 by the President, Chief
Executive Officer or Chairperson of the Board and shall be called by the
President or Secretary at the request in writing of a majority of the Board of
Directors. Such request shall state the purpose or purposes of the proposed
meeting.  The place, date and time of any special meeting shall be determined
by the Board of Directors. Such determination shall include the record date for
determining the stockholders having the right of and to vote at such meeting.

         Section 6.       Notice of Special Meeting.  Written notice of a
special meeting stating the place, date and hour of the meeting and the purpose
or purposes for which the meeting is called shall be given not less than ten
(10) nor more than sixty (60) days before the date of the meeting, to each
stockholder entitled to vote at such meeting.

<PAGE>   4
         Section 7.       Action at Special Meeting.  Business transacted at
any special meeting of stockholders shall be limited to the purposes stated in
the notice.

         Section 8.       Quorum and Adjournments.

                          (a)     The holders of a majority of the stock issued
and outstanding and entitled to vote thereat, present in person or represented
by proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by statute or by the
Certificate of Incorporation, as amended from time to time.  If, however, such
quorum shall not be present or represented at any meeting of the stockholders,
the stockholders entitled to vote thereat, present in person or represented by
proxy, shall have the power to adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present
or represented.  At such adjourned meeting at which a quorum shall be present
or represented, any business may be transacted which might have been transacted
at the meeting as originally notified.  If the adjournment is for more than
thirty (30) days, or if after the adjournment a new record date is fixed for
the adjourned meeting, a notice of the adjourned meeting shall be given to each
stockholder of record entitled to vote at the meeting.

                          (b)     When a quorum is present at any meeting, the
vote of the holders of a majority of the stock having voting power present in
person or represented by proxy shall decide any question brought before such
meeting, unless the question is one upon which by express provision of statutes
or of the Certificate of Incorporation, as amended from time to time, a
different vote is required, in which case such express provision shall govern
and control the decision of such question.

         Section 9.       Voting Rights.  Unless otherwise provided in the
Certificate of Incorporation, as amended from time to time, each stockholder
shall at every meeting of the stockholders be entitled to one (1) vote in
person or by proxy for each share of the capital stock having voting power held
by such stockholder, but no proxy shall be voted on after three (3) years from
its date, unless the proxy provides for a longer period.

         Section 10.      Action Without Meeting.  No action shall be taken by
the stockholders of the corporation except at an annual or special meeting of
stockholders called in accordance with these Bylaws, and no action shall be
taken by the stockholders by written consent.

                                  ARTICLE III
                                   DIRECTORS

         Section 1.       Number, Election, Tenure and Qualification.  The
number of directors which shall constitute the whole Board of Directors shall
be fixed from time to time by resolution of the Board of Directors or by the
Stockholders at an annual meeting of the Stockholders provided that the number

the annual meeting of the Stockholders by a plurality vote of the shares
represented in





                                       4.

person or by proxy and each director elected shall hold office until his or her
successor is elected and qualified unless he or she shall resign, become
disqualified, disabled, or otherwise removed.  Directors need not be
Stockholders.

         Section 2.       Vacancies.  Vacancies may be filled only by a
majority of the Directors then in office, though less than a quorum, or by a
sole remaining Director.  Each Director so chosen shall hold office until a
successor is duly elected and shall qualify or until his or her earlier death,
resignation or removal. If there are no Directors in office, then an election
of Directors may be held in the manner provided by statute.  If, at the time of
filling any vacancy, the Directors then in office shall constitute less than a
majority of the whole Board (as constituted immediately prior to any such
increase), the Court of Chancery may, upon application of any stockholder or
stockholders holding at least ten percent of the total number of the shares at
the time outstanding having the right to vote for such Directors, summarily
order an election to be held to fill any such vacancies, or to replace the
Directors chosen by the Directors then in office.

         Section 3.       Powers.  The business of the corporation shall be
managed by or under the direction of its Board of Directors which may exercise
all such powers of the corporation and do all such lawful acts and things as
are not by statute or by the Certificate of Incorporation, as amended from time
to time, or by these Bylaws directed or required to be exercised or done by the
stockholders.

         Section 4.       Regular and Special Meetings.  The Board of Directors
of the corporation may hold meetings, both regular and special, either within
or without the State of Delaware.

         Section 5.       Annual Meeting.  The annual meeting of each newly
elected Board of Directors shall be held without notice other than this Bylaw
immediately after, and at the  same place as, the annual meeting of
stockholders.  In the event the annual meeting of any newly elected Board of
Directors shall not be held immediately after, and at the same place as, the
annual meeting of stockholders, the meeting may be held at such time and place
as shall be specified in a notice given as hereinafter provided for special
meetings of the Board of Directors.

         Section 6.       Notice of Regular Meetings.  Regular meetings of the
Board of Directors may be held without notice at such time and at such place as
shall from time to time be determined by the Board.

         Section 7.       Notice of Special Meetings.  Special meetings of the
Board may be called by the Chief Executive Officer or President on no less than
forty-eight (48) hours notice to each Director either personally, or by
telephone, mail, telegram or facsimile; special meetings shall be called by the
Chief Executive Officer, President or Secretary in like manner and on like
notice on the written request of two Directors unless the Board consists of
only one Director, in which case special meetings shall be called by the Chief
Executive Officer, President or Secretary in like manner and on like notice on
the written request of the sole Director.  A written waiver of





                                       5.
<PAGE>   6
notice, signed by the person entitled thereto, whether before or after the time
of the meeting stated therein, shall be deemed equivalent to notice.

         Section 8.       Quorum.  At all meetings of the Board a majority of
the Directors shall constitute a quorum for the transaction of business and the
act of a majority of the Directors present at any meeting at which there is a
quorum shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute or by the Certificate of Incorporation, as
amended from time to time.  If a quorum shall not be present at any meeting of
the Board of Directors, the Directors present thereat may adjourn the meeting
from time to time, without notice other than announcement at the meeting, until
a quorum shall be present.

         Section 9.       Action Without Meeting.  Unless otherwise restricted
by the Certificate of Incorporation, as amended from time to time, or these
Bylaws, any action required or permitted to be taken at any meeting of the
Board of Directors or of any committee thereof may be taken without a meeting,
if all members of the Board or committee, as the case may be, consent thereto
in writing, and the writing or writings are filed with the minutes of
proceedings of the Board or committee.

         Section 10.      Meetings by Telephone Conference Calls.  Unless
otherwise restricted by the Certificate of Incorporation, as amended from time
to time, or these Bylaws, members of the Board of Directors, or any committee
designated by the Board of Directors, may participate in a meeting of the Board
of Directors, or any committee, by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

         Section 11.      Committees.

                          (a)     The Board of Directors may, by resolution
passed by a majority of the whole Board, designate one or more committees, each
committee to consist of one or more of the Directors of the corporation.  The
Board may designate one or more Directors as alternate members of any
committee, who may replace any absent or disqualified member at any meeting of
the committee.

                          (b)     In the absence of disqualification of a
member of a committee, the member or members thereof present at any meeting and
not disqualified from voting, whether or not he, she or they constitute a
quorum, may unanimously appoint another member of the Board of Directors to act
at the meeting in the place of any such absent or disqualified member.

                          (c)     Any such committee, to the extent provided in
the resolution of the Board of Directors, shall have and may exercise all the
powers and authority of the Board of Directors in the management of the
business and affairs of the corporation, and may authorize the seal of the
corporation to be affixed to all papers which may require it; but no such





                                       6.

committee shall have the power or authority in reference to amending the

statutes or of the Certificate of Incorporation, as amended from time to time,

thereof in writing, signed by the person or persons entitled to said notice,
whether before or after the time stated therein, shall be deemed equivalent
thereto.

                             CERTIFICATES OF STOCK

         Section 1.       Certificates of Stock.

                          (a)     Every holder of stock in the corporation
shall be entitled to have a certificate, signed by, or in the name of the
corporation by, the Chairperson or Vice Chairperson of the Board of Directors,
or the President or a Vice President and the Chief Financial Officer or an
Assistant Chief Financial Officer, or the Secretary or an Assistant Secretary
of the corporation, certifying the number of shares owned by him or her in the
corporation.

                          (b)     Certificates may be issued for partly paid
shares and in such case upon the face or back of the certificates issued to
represent any such partly paid shares, the total amount of the consideration to
be paid therefor, and the amount paid thereon shall be specified.

                          (c)     If the corporation shall be authorized to
issue more than one class of stock or more than one series of any class, the
powers, designations, preferences and relative, participating, optional or
other special rights of each class of stock or series thereof and the
qualifications, limitations or restrictions of such preferences and/or rights
shall be set forth in full or summarized on the face or back of the certificate
which the corporation shall issue to represent such class or series of stock,
provided that, except as otherwise provided in Section 202 of the General
Corporation Law of Delaware, in lieu of the foregoing requirements, there may
be set forth on the face or back of the certificate which the corporation shall
issue to represent such class or series of stock, a statement that the
corporation will furnish without charge to each stockholder who so requests the
powers, designations, preferences and relative, participating, optional or
other special rights of each class of stock or series thereof and the
qualifications, limitations or restrictions of such preferences and/or rights.

         Section 2.       Execution of Certificates.  Any or all of the
signatures on the certificate may be facsimile.  In case any officer, transfer
agent or registrar who has signed or whose facsimile signature has been placed
upon a certificate shall have ceased to be such officer, transfer agent or
registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if he or she were such officer, transfer
agent or registrar at the date of issue.

         Section 3.       Lost Certificates.  The Board of Directors may direct
a new certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the corporation alleged to have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed.  When
authorizing such issue of a new certificate or certificates, the Board of
Directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or his or her legal representative, to advertise the





                                      11.
<PAGE>   12
same in such manner as it shall require and/or to give the corporation a bond
in such sum as it may direct as indemnity against any claim that may be made
against the corporation with respect to the certificate alleged to have been
lost, stolen or destroyed.

         Section 4.       Transfer of Stock.  Upon surrender to the corporation
or the transfer agent of the corporation of a certificate for shares duly
endorsed or accompanied by proper evidence of succession, assignation or
authority to transfer, it shall be the duty of the corporation to issue a new
certificate to the person entitled thereto, cancel the old certificate and
record the transaction upon its books.

         Section 5.       Fixing Record Date.  In order that the corporation
may determine the stockholders entitled to notice of or to vote at any meeting
of stockholder or any adjournment thereof, or entitled to receive payment of
any dividend or other distribution or allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion or exchange of stock
or for the purpose of any other lawful action, the Board of Directors may fix,
in advance, a record date, which shall not be more than sixty (60) nor less
than ten (10) days before the date of such meeting, nor more than sixty (60)
days prior to any other action.  A determination of stockholders of record
entitled to notice of or to vote at a meeting of stockholders shall apply to
any adjournment of the meeting; provided, however, that the Board of Directors
may fix a new record date for the adjourned meeting.

         Section 6.       Registered Stockholders.  The corporation shall be
entitled to recognize the exclusive right of a person registered on its books
as the owner of shares to receive dividends, and to vote as such owner, and to
hold liable for calls and assessments a person registered on its books as the
owner of shares and shall not be bound to recognize any equitable or other
claim to or interest in such share or shares on the part of any other person,
whether or not it shall have express or other notice thereof, except as
otherwise provided by the laws of Delaware.

                                INDEMNIFICATION

         Section 1.       Indemnification of Directors and Executive Officers.
The corporation shall indemnify its Directors and executive officers to the
fullest extent not prohibited by the Delaware General Corporation Law;
provided, however, that the corporation may limit the extent of such
indemnification by individual contracts with its Directors and executive
officers; and, provided, further, that the corporation shall not be required to
indemnify any Director or executive officer in connection with any proceeding
(or part thereof) initiated by such person or any proceeding by such person
against the corporation or its Directors, officers, employees or other agents
unless (i) such indemnification is expressly required to be made by law, (ii)
the proceeding was authorized by the Board of Directors of the corporation, and
(iii) such indemnification is provided by the corporation, in its sole
discretion, pursuant to the powers vested in the corporation under the Delaware
General Corporation Law.

         Section 2.       Indemnification of Other Officers, Employees and
Other Agents.  The corporation shall have power to indemnify its other
officers, employees and other agents as set forth in the Delaware General
Corporation Law.

         Section 3.       Good Faith.

                          (a)     For purposes of any determination under this
Bylaw, a Director or officer shall be deemed to have acted in good faith and in
a manner reasonably believed to be in or not opposed to the best interests of
the corporation, and, with respect to any criminal action or proceeding, to
have had no reasonable cause to believe that any conduct was unlawful, if such
Director's or officer's action is based on information, opinions, reports and
statements, including financial statements and other financial data, in each
case prepared or presented by:

                                  (1)      one or more officers or employees of
the corporation whom the Director or executive officer believed to be reliable
and competent in the matters presented;

                                  (2)      counsel, independent accountants or
other persons as to matters which the Director or executive officer believed to
be within such person's professional competence; and

                                  (3)      with respect to a Director, a
committee of the Board upon which such Director does not serve, as to matters
within such Committee's designated authority, which committee the Director
believes to merit confidence; so long as, in each case, the Director or
executive officer acts without knowledge that would cause such reliance to be
unwarranted.

                          (b)     The termination of any proceeding by
judgment, order, settlement, conviction or upon a plea of nolo contendere or
its equivalent shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which was reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal proceeding, that the person had reasonable cause to believe that his
or her consent was unlawful.

                          (c)     The provisions of this Section 3 shall not be
deemed to be exclusive or to limit in any way the circumstances in which a
person may be deemed to have met the applicable standard of conduct set forth
by the Delaware General Corporation Law.

         Section 4.       Expenses.

                          (a)     The corporation shall advance, prior to the
final disposition of any proceeding, promptly following request therefor, all
expenses incurred by any Director or officer in connection with such proceeding
upon receipt of an undertaking by or on behalf of such person





                                      13.
<PAGE>   14
to repay said amounts if it should be determined ultimately that such person is
not entitled to be indemnified under this Bylaw or otherwise.

                          (b)     Notwithstanding the foregoing, unless
otherwise determined pursuant to Section 4 of this Bylaw, no advance shall be
made by the corporation if a determination is reasonably and promptly made (i)
by the Board of Directors by a majority vote of a quorum consisting of
Directors who were not parties to the proceeding, or (ii) if such quorum is not
obtainable, or, even if obtainable, a quorum of disinterested Directors so
directs, by independent legal counsel in a written opinion, that the facts
known to the decision-making party at the time such determination is made
demonstrate clearly and convincingly that such person acted in bad faith or in
a manner that such person did not believe to be in or not opposed to the best
interests of the corporation.

         Section 5.       Enforcement.  Without the necessity of entering into
an express contract, all rights to indemnification and advances to Directors
and officers under this Bylaw shall be deemed to be contractual rights and be
effective to the same extent and as if provided for in a contract between the
corporation and the Director or officer.  Any right to indemnification or
advances granted by this Bylaw to a Director or officer shall be enforceable by
or on behalf of the person holding such right in any court of competent
jurisdiction if (i) the claim for indemnification or advances is denied, in
whole or in part, or (ii) no disposition of such claim is made within ninety
(90) days of request therefor.  The claimant in such enforcement action, if
successful in whole or in part, shall be entitled to be paid also the expense
of prosecuting his or her claim.  The corporation shall be entitled to raise as
a defense to any such action that the claimant has not met the standards of
conduct that make it permissible under the Delaware General Corporation Law for
the corporation to indemnify the claimant for the amount claimed.  Neither the
failure of the corporation (including its Board of Directors, independent legal
counsel or its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he or she has met the applicable standard of conduct
set forth in the Delaware General Corporation Law, nor an actual determination
by the corporation (including its Board of Directors, independent legal counsel
or its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

         Section 6.       Non-Exclusivity of Rights.  The rights conferred on
any person by this Bylaw shall not be exclusive of any other right which such
person may have or hereafter acquire under any statute, provision of the
Certificate of Incorporation, as amended from time to time, Bylaws, agreement,
vote of stockholders or disinterested Directors or otherwise, both as to action
in his or her official capacity and as to action in another capacity while
holding office.  The corporation is specifically authorized to enter into
individual contracts with any or all of its Directors, officers, employees or
agents respecting indemnification and advances, to the fullest extent not
prohibited by the Delaware General Corporation Law.





                                      14.
<PAGE>   15
         Section 7.       Survival of Rights.  The rights conferred on any
person by this Bylaw shall continue as to a person who has ceased to be a
Director, officer, employee or other agent and shall inure to the benefit of
the heirs, executors and administrators of such a person.

         Section 8.       Insurance.  To the fullest extent permitted by the
Delaware General Corporation Law, the corporation, upon approval by the Board
of Directors, may purchase insurance on behalf of any person required or
permitted to be indemnified pursuant to this Bylaw.

         Section 9.       Amendments.  Any repeal or modification of this Bylaw
shall only be prospective and shall not affect the rights under this Bylaw in
effect at the time of the alleged occurrence of any action or omission to act
that is the cause of any proceeding against any agent of the corporation.

         Section 10.      Saving Clause.  If this Bylaw or any portion hereof
shall be invalidated on any ground by any court of competent jurisdiction, then
the corporation shall nevertheless indemnify each Director and officer to the
full extent not prohibited by any applicable portion of this Bylaw that shall
not have been invalidated, or by any other applicable law.

         Section 11.      Certain Definitions.  For the purposes of this Bylaw,
the following definitions shall apply:

                          (a)     The term "proceeding" shall be broadly
construed and shall include, without limitation, the investigation,
preparation, prosecution, defense, settlement, arbitration and appeal of, and
the giving of the testimony in, any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative.

                          (b)     The term "expenses" shall be broadly
construed and shall include, without limitation, court costs, attorneys' fees,
witness fees, fines, amounts paid in settlement or judgment and any other costs

                          (c)     The term the "corporation" shall include, in
addition to the resulting corporation, any constituent corporation (including
any constituent of a constituent) absorbed in a consolidation or merger which,
if its separate existence had continued, would have had power and authority to
indemnify its Directors, officers, and employees or agents, so that any person
who is or was a Director, officer, employee or agent of such constituent
corporation, or is or was serving at the request of such constituent
corporation as a Director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, shall stand in the same
position under the provisions of this Bylaw with respect to the resulting or
surviving corporation as he or she would have with respect to such constituent
corporation if its separate existence had continued.

Director, officer, employee, trustee or agent of another corporation,
partnership, joint venture, trust or other enterprise.

                          (e)     References to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include any
service as a Director, officer, employee or agent of the corporation which
imposes duties on, or involves services by, such Director, officer, employee,
or agent with respect to an employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner he or she
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the corporation" as referred to in this Bylaw.

reasonably be expected to benefit the corporation.  The loan, guarantee or
other assistance may be with or without interest and may be unsecured, or
secured in such manner as the Board of Directors shall approve, including,
without limitation, a pledge of shares of stock of the corporation.  Nothing in
this Bylaw shall be deemed to deny, limit or restrict the powers of guaranty or
warranty of the corporation at common law or under any statute.

     Re:  SCC Communications Corp. Registration Statement on Form S-1 for
          3,300,000 Shares of Common Stock

Ladies and Gentlemen:

     We have acted as counsel to SCC Communications Corp., a Delaware
corporation (the "Company"), in connection with the proposed issuance and sale
by the Company of up to 3,300,000 shares of the Company's Common Stock (the
"Shares") pursuant to the Company's Registration Statement on Form S-1 (the
"Registration Statement") filed with the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the "Act").

     This opinion is being furnished in accordance with the requirements of Item
16(a) of Form S-1 and Item 601(b)(5)(i) of Regulation S-K.

     We have reviewed the Company's charter documents and the corporate
proceedings taken by the Company in connection with the issuance and sale of the
Shares. Based on such review, we are of the opinion that the Shares have been
duly authorized, and if, as and when issued in accordance with the Registration
Statement and the related prospectus (as amended and supplemented through the
date of issuance) will be legally issued, fully paid and nonassessable.

     We consent to the filing of this opinion letter as Exhibit 5.1 to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the prospectus which is part of the Registration Statement.
In giving this consent, we do not thereby admit that we are within the category
of persons whose consent is required under Section 7 of the Act, the rules and
regulations of the Securities and Exchange Commission promulgated thereunder, or
Item 509 of Regulation S-K.

                            SCC COMMUNICATIONS CORP.
                           1998 STOCK INCENTIVE PLAN


                                  ARTICLE ONE

                               GENERAL PROVISIONS


       I.        PURPOSE OF THE PLAN

                 This 1998 Stock Incentive Plan is intended to promote the
interests of SCC Communications Corp., a Delaware corporation, by providing
eligible persons with the opportunity to acquire a proprietary interest, or
otherwise increase their proprietary interest, in the Corporation as an
incentive for them to remain in the service of the Corporation.

                 Capitalized terms shall have the meanings assigned to such
terms in the attached Appendix.

     II.         STRUCTURE OF THE PLAN

                 A.       The Plan shall be divided into five separate equity
programs:

                          -       the Discretionary Option Grant Program under
which eligible persons may, at the discretion of the Plan Administrator, be
granted options to purchase shares of Common Stock,

                          -       the Salary Investment Option Grant Program,
which may, in the Plan Administrator's discretion, be activated for one or more
calendar years and thereby allow eligible employees the opportunity to invest a
portion of their base salary invested each year in special option grants,

                          -       the Stock Issuance Program under which
eligible persons may, at the discretion of the Plan Administrator, be issued
shares of Common Stock directly, either through the immediate purchase of such
shares or as a bonus for services rendered the Corporation (or any Parent or
Subsidiary),

                          -       the Automatic Option Grant Program under
which eligible non-employee Board members shall automatically receive option
grants at periodic intervals to purchase shares of Common Stock, and
<PAGE>   2
                          -       the Director Fee Option Grant Program, which
may, in the Plan Administrator's discretion, be activated for one or more
calendar years and thereby allow the non-employee Board members the opportunity
to apply all or any portion of their annual retainer fee otherwise payable in
cash to a special option grant.

                 B.       The provisions of Articles One and Seven shall apply
to all equity programs under the Plan and shall govern the interests of all
persons under the Plan.

     III.        ADMINISTRATION OF THE PLAN

                 A.       The Primary Committee shall have sole and exclusive
authority to administer the Discretionary Option Grant and Stock Issuance
Programs with respect to Section 16 Insiders. Administration of the
Discretionary Option Grant and Stock Issuance Programs with respect to all
other persons eligible to participate in those programs may, at the Board's
discretion, be vested in the Primary Committee or a Secondary Committee, or the
Board may retain the power to administer those programs with respect to all
such persons.

                 B.       Members of the Primary Committee or any Secondary
Committee shall serve for such period of time as the Board may determine and
may be removed by the Board at any time.  The Board may also at any time
terminate the functions of any Secondary Committee and reassume all powers and
authority previously delegated to such committee.

                 C.       Each Plan Administrator shall, within the scope of
its administrative functions under the Plan, have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for proper administration of the Discretionary
Option Grant and Stock Issuance Programs and to make such determinations under,
and issue such interpretations of, the provisions of such programs and any
outstanding options or stock issuances thereunder as it may deem necessary or
advisable.  Decisions of the Plan Administrator within the scope of its
administrative functions under the Plan shall be final and binding on all
parties who have an interest in the Discretionary Option Grant and Stock
Issuance Programs under its jurisdiction or any stock option or stock issuance
thereunder.

                 D.       The Primary Committee shall have the sole and
exclusive authority to determine which Section 16 Insiders and other highly
compensated Employees shall be eligible for participation in the Salary
Investment Option Grant Program for one or more calendar years.  However, all
option grants under the Salary Investment Option Grant Program shall be made in
accordance with the express terms of that program, and the Primary Committee
shall not exercise any discretionary functions with respect to the option
grants made under that program.

                 E.       Service on the Primary Committee or the Secondary
Committee shall constitute service as a Board member, and members of each such
committee shall accordingly be entitled to full indemnification and
reimbursement as Board members for their service on such


                                     2.
<PAGE>   3
committee.  No member of the Primary Committee or the Secondary Committee shall
be liable for any act or omission made in good faith with respect to the Plan
or any option grants or stock issuances under the Plan.

                 F.       Administration of the Automatic Option Grant and
Director Fee Option Grant Programs shall be self-executing in accordance with
the terms of those programs, and no Plan Administrator shall exercise any
discretionary functions with respect to any option grants or stock issuances
made under those programs.

     IV.         ELIGIBILITY

                 A.       The persons eligible to participate in the
Discretionary Option Grant and Stock Issuance Programs are as follows:

                               (i)         Employees,

                              (ii)         non-employee members of the Board or
         the board of directors of any Parent or Subsidiary, and

                             (iii)         consultants and other independent
         advisors who provide services to the Corporation (or any Parent or
         Subsidiary).

                 B.       Only Employees who are Section 16 Insiders or other
highly compensated individuals shall be eligible to participate in the Salary
Investment Option Grant Program.

                 C.       Each Plan Administrator shall, within the scope of
its administrative jurisdiction under the Plan, have full authority to
determine, (i) with respect to the option grants under the Discretionary Option
Grant Program, which eligible persons are to receive option grants, the time or
times when such option grants are to be made, the number of shares to be
covered by each such grant, the status of the granted option as either an
Incentive Option or a Non-Statutory Option, the time or times when each option
is to become exercisable, the vesting schedule (if any) applicable to the
option shares and the maximum term for which the option is to remain
outstanding and (ii) with respect to stock issuances under the Stock Issuance
Program, which eligible persons are to receive stock issuances, the time or
times when such issuances are to be made, the number of shares to be issued to
each Participant, the vesting schedule (if any) applicable to the issued shares
and the consideration for such shares.

                 D.       The Plan Administrator shall have the absolute
discretion either to grant options in accordance with the Discretionary Option
Grant Program or to effect stock issuances in accordance with the Stock
Issuance Program.





                                       3.
<PAGE>   4
                 E.       The individuals who shall be eligible to participate
in the Automatic Option Grant Program shall be limited to (i) those individuals
who first become non-employee Board members on or after the Underwriting Date,
whether through appointment by the Board or election by the Corporation's
stockholders, and (ii) those individuals who continue to serve as non-employee
Board members at one or more Annual Stockholders Meetings held after the
Underwriting Date, including individuals who first joined the Board prior to
the Underwriting Date.  A non-employee Board member who has previously been in
the employ of the Corporation (or any Parent or Subsidiary) shall not be
eligible to receive an option grant under the Automatic Option Grant Program at
the time he or she first becomes a non-employee Board member, but shall be
eligible to receive periodic option grants under the Automatic Option Grant
Program while he or she continues to serve as a non-employee Board member.

                 F.       All non-employee Board members shall be eligible to
participate in the Director Fee Option Grant Program.

       V.        STOCK SUBJECT TO THE PLAN

                 A.       The stock issuable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares
repurchased by the Corporation on the open market.  The maximum number of
shares of Common Stock initially reserved for issuance over the term of the
Plan shall not exceed 1,901,055 shares, which shall consist of (i) the number
of shares which remained available for issuance, as of the Plan Effective Time,
under the Predecessor Plan as last approved by the Corporation's stockholders,
including the shares subject to outstanding options under that Predecessor
Plan, and (ii) an additional increase of approximately 500,000 shares
authorized by the Board and the stockholders prior to the Section 12
Registration Date.  In addition, the share reserve will automatically be
increased on the first trading day in January of each calendar year, beginning
with the 1999 calendar year, by an amount equal to 3% of the total number of
shares of Common Stock outstanding on the last trading day in December of the
immediately preceding calendar year, but in no event shall any such annual
increase exceed 731,000 shares.  To the extent any unvested shares of Common
Stock outstanding under the Predecessor Plan as of the Plan Effective Time are
subsequently repurchased by the Corporation, at the option exercise price paid
per share, in connection with the holder's termination of service prior to
vesting in the shares, those repurchased shares shall be added to the reserve
of Common Stock available for issuance under the Plan, but in no event shall
more than 476,776 shares be added to the reserve from such repurchases.

                 B.       No one person participating in the Plan may receive
options, separately exercisable stock appreciation rights and direct stock
issuances for more than 500,000 shares of Common Stock in the aggregate per
calendar year, beginning with the 1998 calendar year.

                 C.       Shares of Common Stock subject to outstanding options
(including options incorporated into this Plan from the Predecessor Plan) shall
be available for subsequent issuance under the Plan to the extent (i) those
options expire or terminate for any reason prior to exercise





                                       4.
<PAGE>   5
in full or (ii) the options are cancelled in accordance with the
cancellation-regrant provisions of Article Two.  Unvested shares issued under
the Plan and subsequently repurchased by the Corporation (including unvested
shares issued under the Predecessor Plan and repurchased by the Corporation at
or after the Plan Effective Time), at the original issue price paid per share,
pursuant to the Corporation's repurchase rights under the Plan shall be added
back to the number of shares of Common Stock reserved for issuance under the
Plan and shall accordingly be available for reissuance through one or more
subsequent option grants or direct stock issuances under the Plan.  However,
should the exercise price of an option under the Plan be paid with shares of
Common Stock or should shares of Common Stock otherwise issuable under the Plan
be withheld by the Corporation in satisfaction of the withholding taxes
incurred in connection with the exercise of an option or the vesting of a stock
issuance under the Plan, then the number of shares of Common Stock available
for issuance under the Plan shall be reduced by the gross number of shares for
which the option is exercised or which vest under the stock issuance, and not
by the net number of shares of Common Stock issued to the holder of such option
or stock issuance. Shares of Common Stock underlying one or more stock
appreciation rights exercised under Section IV of Article Two of the Plan shall
NOT be available for subsequent issuance under the Plan.

                 D.       If any change is made to the Common Stock by reason
of any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a
class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and/or class of securities
issuable under the Plan, (ii) the maximum number and/or class of securities by
which the share reserve may increase each calendar year pursuant to the
automatic share increase provisions of the Plan, (iii) the number and/or class
of securities for which any one person may be granted stock options, separately
exercisable stock appreciation rights and direct stock issuances under the Plan
per calendar year, (iv) the number and/or class of securities for which grants
are subsequently to be made under the Automatic Option Grant Program to new and
continuing non-employee Board members, (v) the number and/or class of
securities and the exercise price per share in effect under each outstanding
option under the Plan and (vi) the number and/or class of securities and price
per share in effect under each outstanding option incorporated into this Plan
from the Predecessor Plan.  Such adjustments to the outstanding options are to
be effected in a manner which shall preclude the enlargement or dilution of
rights and benefits under such options. The adjustments determined by the Plan
Administrator shall be final, binding and conclusive.

                       DISCRETIONARY OPTION GRANT PROGRAM


       I.        OPTION TERMS

                 Each option shall be evidenced by one or more documents in the
form approved by the Plan Administrator; provided, however, that each such
document shall comply with the terms specified below.  Each document evidencing
an Incentive Option shall, in addition, be subject to the provisions of the
Plan applicable to such options.

                 A.       EXERCISE PRICE.

                          1.      The exercise price per share shall be fixed
by the Plan Administrator but shall not be less than one hundred percent (100%)
of the Fair Market Value per share of Common Stock on the option grant date.

                          2.      The exercise price shall become immediately
due upon exercise of the option and shall, subject to the provisions of Section
I of Article Six and the documents evidencing the option, be payable in one or
more of the forms specified below:

                               (i)         cash or check made payable to the 
         Corporation,

                              (ii)         shares of Common Stock held for the
         requisite period necessary to avoid a charge to the Corporation's
         earnings for financial reporting purposes and valued at Fair Market
         Value on the Exercise Date, or

                             (iii)         to the extent the option is
         exercised for vested shares, through a special sale and remittance
         procedure pursuant to which the Optionee shall concurrently provide
         irrevocable instructions to (a) a Corporation-designated brokerage
         firm to effect the immediate sale of the purchased shares and remit to
         the Corporation, out of the sale proceeds available on the settlement
         date, sufficient funds to cover the aggregate exercise price payable
         for the purchased shares plus all applicable Federal, state and local
         income and employment taxes required to be withheld by the Corporation
         by reason of such exercise and (b) the Corporation to deliver the
         certificates for the purchased shares directly to such brokerage firm
         in order to complete the sale.

                 Except to the extent such sale and remittance procedure is
utilized, payment of the exercise price for the purchased shares must be made
on the Exercise Date.

                 B.       EXERCISE AND TERM OF OPTIONS.  Each option shall be
exercisable at such time or times, during such period and for such number of
shares as shall be determined by the Plan Administrator and set forth in the
documents evidencing the option.  However, no option shall have a term in
excess of ten (10) years measured from the option grant date.

                 C.       EFFECT OF TERMINATION OF SERVICE.

                          1.      The following provisions shall govern the
exercise of any options held by the Optionee at the time of cessation of
Service or death:

                               (i)         Any option outstanding at the time
         of the Optionee's cessation of Service for any reason shall remain
         exercisable for such period of time thereafter as shall be determined
         by the Plan Administrator and set forth in the documents evidencing
         the option, but no such option shall be exercisable after the
         expiration of the option term.

                              (ii)         Any option exercisable in whole or
         in part by the Optionee at the time of death may be subsequently
         exercised by the personal representative of the Optionee's estate or
         by the person or persons to whom the option is transferred pursuant to
         the Optionee's will or in accordance with the laws of descent and
         distribution.

                             (iii)         Should the Optionee's Service be
         terminated for Misconduct, then all outstanding options held by the
         Optionee shall terminate immediately and cease to be outstanding.

                              (iv)         During the applicable post-Service
         exercise period, the option may not be exercised in the aggregate for
         more than the number of vested shares for which the option is
         exercisable on the date of the Optionee's cessation of Service.  Upon
         the expiration of the applicable exercise period or (if earlier) upon
         the expiration of the option term, the option shall terminate and
         cease to be outstanding for any vested shares for which the option has
         not been exercised.  However, the option shall, immediately upon the
         Optionee's cessation of Service, terminate and cease to be outstanding
         to the extent the option is not otherwise at that time exercisable for
         vested shares.

                          2.      The Plan Administrator shall have complete
discretion, exercisable either at the time an option is granted or at any time
while the option remains outstanding, to:

                                (i)        extend the period of time for which
         the option is to remain exercisable following the Optionee's cessation
         of Service from the limited exercise period otherwise in effect for
         that option to such greater period of time





                                       7.
<PAGE>   8
         as the Plan Administrator shall deem appropriate, but in no event
         beyond the expiration of the option term, and/or

                               (ii)        permit the option to be exercised,
         during the applicable post-Service exercise period, not only with
         respect to the number of vested shares of Common Stock for which such
         option is exercisable at the time of the Optionee's cessation of
         Service but also with respect to one or more additional installments
         in which the Optionee would have vested had the Optionee continued in
         Service.

                 D.       STOCKHOLDER RIGHTS.  The holder of an option shall
have no stockholder rights with respect to the shares subject to the option
until such person shall have exercised the option, paid the exercise price and
become a holder of record of the purchased shares.

                 E.       REPURCHASE RIGHTS.  The Plan Administrator shall have
the discretion to grant options which are exercisable for unvested shares of
Common Stock.  Should the Optionee cease Service while holding such unvested
shares, the Corporation shall have the right to repurchase, at the exercise
price paid per share, any or all of those unvested shares.  The terms upon
which such repurchase right shall be exercisable (including the period and
procedure for exercise and the appropriate vesting schedule for the purchased
shares) shall be established by the Plan Administrator and set forth in the
document evidencing such repurchase right.

                 F.       LIMITED TRANSFERABILITY OF OPTIONS.  During the
lifetime of the Optionee, Incentive Options shall be exercisable only by the
Optionee and shall not be assignable or transferable other than by will or by
the laws of descent and distribution following the Optionee's death.
Non-Statutory Options shall be subject to the same restrictions, except that a
Non-Statutory Option may, in connection with the Optionee's estate plan, be
assigned in whole or in part during the Optionee's lifetime to one or more
members of the Optionee's immediate family or to a trust established
exclusively for one or more such family members.  The assigned portion may only
be exercised by the person or persons who acquire a proprietary interest in the
option pursuant to the assignment. The terms applicable to the assigned portion
shall be the same as those in effect for the option immediately prior to such
assignment and shall be set forth in such documents issued to the assignee as
the Plan Administrator may deem appropriate.

     II.         INCENTIVE OPTIONS

                 The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Seven shall be applicable to Incentive
Options.  Options which are specifically designated as Non-Statutory Options
when issued under the Plan shall not be subject to the terms of this Section
II.

                 A.       ELIGIBILITY.  Incentive Options may only be granted
to Employees.





                                       8.
<PAGE>   9
                 B.       EXERCISE PRICE.  The exercise price per share shall
not be less than one hundred percent (100%) of the Fair Market Value per share
of Common Stock on the option grant date.

                 C.       DOLLAR LIMITATION.  The aggregate Fair Market Value
of the shares of Common Stock (determined as of the respective date or dates of
grant) for which one or more options granted to any Employee under the Plan (or
any other option plan of the Corporation or any Parent or Subsidiary) may for
the first time become exercisable as Incentive Options during any one calendar
year shall not exceed the sum of One Hundred Thousand Dollars ($100,000).  To
the extent the Employee holds two (2) or more such options which become
exercisable for the first time in the same calendar year, the foregoing
limitation on the exercisability of such options as Incentive Options shall be
applied on the basis of the order in which such options are granted.

                 D.       10% STOCKHOLDER.  If any Employee to whom an
Incentive Option is granted is a 10% Stockholder, then the exercise price per
share shall not be less than one hundred ten percent (110%) of the Fair Market
Value per share of Common Stock on the option grant date, and the option term
shall not exceed five (5) years measured from the option grant date.

     III.        CORPORATE TRANSACTION/CHANGE IN CONTROL

                 A.       In the event of any Corporate Transaction, each
outstanding option shall automatically accelerate so that each such option
shall, immediately prior to the effective date of the Corporate Transaction,
become fully exercisable with respect to the total number of shares of Common
Stock at the time subject to such option and may be exercised for any or all of
those shares as fully vested shares of Class A Common Stock.  However, an
outstanding option shall NOT become exercisable on such an accelerated basis if
and to the extent:  (i) such option is, in connection with the Corporate
Transaction, to be assumed by the successor corporation (or parent thereof) or
(ii) such option is to be replaced with a cash incentive program of the
successor corporation which preserves the spread existing at the time of the
Corporate Transaction on any shares for which the option is not otherwise at
that time exercisable and provides for subsequent payout in accordance with the
same exercise/vesting schedule applicable to those option shares or (iii) the
acceleration of such option is subject to other limitations imposed by the Plan
Administrator at the time of the option grant.

                 B.       All outstanding repurchase rights shall automatically
terminate, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Corporate Transaction,
except to the extent: (i) those repurchase rights are to be assigned to the
successor corporation (or parent thereof) in connection with such Corporate
Transaction or (ii) such accelerated vesting is precluded by other limitations
imposed by the Plan Administrator at the time the repurchase right is issued.





                                       9.
<PAGE>   10
                 C.       Immediately following the consummation of the
Corporate Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

                 D.       Each option which is assumed in connection with a
Corporate Transaction shall be appropriately adjusted, immediately after such
Corporate Transaction, to apply to the number and class of securities which
would have been issuable to the Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction.  Appropriate adjustments to reflect such Corporate Transaction
shall also be made to (i) the exercise price payable per share under each
outstanding option, provided the aggregate exercise price payable for such
securities shall remain the same, (ii) the maximum number and/or class of
securities available for issuance over the remaining term of the Plan and (iii)
the maximum number and/or class of securities for which any one person may be
granted stock options, separately exercisable stock appreciation rights and
direct stock issuances under the Plan per calendar year.

                 E.       The Plan Administrator shall have the discretionary
authority to provide for the automatic acceleration of one or more outstanding
options under the Discretionary Option Grant Program upon the occurrence of a
Corporate Transaction, whether or not those options are to be assumed in the
Corporate Transaction, so that each such option shall, immediately prior to the
effect date of such Corporate Transaction, become fully exercisable with
respect to the total number of shares of Common Stock at the time subject to
that option and may be exercised for any or all of those shares as fully vested
shares of Common Stock. In addition, the Plan Administrator shall have the
discretionary authority to structure one or more of the Corporation's
repurchase rights under the Discretionary Option Grant Program so that those
rights shall not be assignable in connection with such Corporate Transaction
and shall accordingly terminate upon the consummation of such Corporate
Transaction, and the shares subject to those terminated rights shall thereupon
vest in full.

                 F.       The Plan Administrator shall have full power and
authority, exercisable either at the time the option is granted or at any time
while the option remains outstanding, to provide for the automatic acceleration
of one or more outstanding options under the Discretionary Option Grant Program
in the event the Optionee's Service is subsequently terminated by reason of an
Involuntary Termination within a designated period (not to exceed eighteen (18)
months) following the effective date of any Corporate Transaction in which
those options are assumed and do not otherwise accelerate.  Any options so
accelerated shall remain exercisable for fully vested shares until the earlier
of (i) the expiration of the option term or (ii) the expiration of the one (1)
year period measured from the effective date of the Involuntary Termination.
In addition, the Plan Administrator may provide that one or more of the
Corporation's outstanding repurchase rights with respect to shares held by the
Optionee at the time of such Involuntary Termination shall immediately
terminate, and the shares subject to those terminated repurchase rights shall
accordingly vest in full.





                                      10.
<PAGE>   11
                 G.       The Plan Administrator shall have the discretionary
authority to provide for the automatic acceleration of one or more outstanding
options under the Discretionary Option Grant Program upon the occurrence of a
Change in Control so that each such option shall, immediately prior to the
effect date of such Change in Control, become fully exercisable with respect to
the total number of shares of Common Stock at the time subject to that option
and may be exercised for any or all of those shares as fully vested shares of
Common Stock. In addition, the Plan Administrator shall have the discretionary
authority to structure one or more of the Corporation's repurchase rights under
the Discretionary Option Grant Program so that those rights shall terminate
automatically upon the consummation of such Change in Control, and the shares
subject to those terminated rights shall thereupon vest in full.
Alternatively, the Plan Administrator may condition the automatic acceleration
of one or more outstanding options under the Discretionary Option Grant Program
and the termination of one or more of the Corporation's outstanding repurchase
rights under such program upon the subsequent termination of the Optionee's
Service by reason of an Involuntary Termination within a designated period (not
to exceed eighteen (18) months) following the effective date of such Change in
Control.  Each option so accelerated shall remain exercisable for fully vested
shares until the earlier of (i) the expiration of the option term or (ii) the
expiration of the one (1) year period measured from the effective date of
Optionee's cessation of Service.

                 H.       The portion of any Incentive Option accelerated in
connection with a Corporate Transaction or Change in Control shall remain
exercisable as an Incentive Option only to the extent the applicable One
Hundred Thousand Dollar ($100,000) limitation is not exceeded.  To the extent
such dollar limitation is exceeded, the accelerated portion of such option
shall be exercisable as a Nonstatutory Option under the Federal tax laws.

                 I.       The outstanding options shall in no way affect the
right of the Corporation to adjust, reclassify, reorganize or otherwise change
its capital or business structure or to merge, consolidate, dissolve, liquidate
or sell or transfer all or any part of its business or assets.

     IV.         CANCELLATION AND REGRANT OF OPTIONS

                 The Plan Administrator shall have the authority to effect, at
any time and from time to time, with the consent of the affected option
holders, the cancellation of any or all outstanding options under the
Discretionary Option Grant Program (including outstanding options incorporated
from the Predecessor Plan) and to grant in substitution new options covering
the same or different number of shares of Common Stock but with an exercise
price per share based on the Fair Market Value per share of Common Stock on the
new grant date.

       V.        STOCK APPRECIATION RIGHTS

                 A.       The Plan Administrator shall have full power and
authority to grant to selected Optionees tandem stock appreciation rights
and/or limited stock appreciation rights.





                                      11.
<PAGE>   12
                 B.       The following terms shall govern the grant and
exercise of tandem stock appreciation rights:

                               (i)         One or more Optionees may be granted
         the right, exercisable upon such terms as the Plan Administrator may
         establish, to elect between the exercise of the underlying option for
         shares of Common Stock and the surrender of that option in exchange
         for a distribution from the Corporation in an amount equal to the
         excess of (a) the Fair Market Value (on the option surrender date) of
         the number of shares in which the Optionee is at the time vested under
         the surrendered option (or surrendered portion thereof) over (b) the
         aggregate exercise price payable for such shares.

                              (ii)         No such option surrender shall be
         effective unless it is approved by the Plan Administrator, either at
         the time of the actual option surrender or at any earlier time.  If
         the surrender is so approved, then the distribution to which the
         Optionee shall be entitled may be made in shares of Common Stock
         valued at Fair Market Value on the option surrender date, in cash, or
         partly in shares and partly in cash, as the Plan Administrator shall
         in its sole discretion deem appropriate.

                             (iii)         If the surrender of an option is not
         approved by the Plan Administrator, then the Optionee shall retain
         whatever rights the Optionee had under the surrendered option (or
         surrendered portion thereof) on the option surrender date and may
         exercise such rights at any time prior to the later of (a) five (5)
         business days after the receipt of the rejection notice or (b) the
         last day on which the option is otherwise exercisable in accordance
         with the terms of the documents evidencing such option, but in no
         event may such rights be exercised more than ten (10) years after the
         option grant date.

                 C.       The following terms shall govern the grant and
exercise of limited stock appreciation rights:

                               (i)         One or more Section 16 Insiders may
         be granted limited stock appreciation rights with respect to their
         outstanding options.

                              (ii)         Upon the occurrence of a Hostile
         Take-Over, each individual holding one or more options with such a
         limited stock appreciation right shall have the unconditional right
         (exercisable for a thirty (30)-day period following such Hostile
         Take-Over) to surrender each such option to the Corporation, to the
         extent the option is at the time exercisable for vested shares of
         Common Stock.  In return for the surrendered option, the Optionee
         shall receive a cash distribution from the Corporation in an amount
         equal to the excess of (A) the Take-Over Price of the shares of Common
         Stock which are at the time vested





                                      12.
<PAGE>   13
         under each surrendered option (or surrendered portion thereof) over
         (B) the aggregate exercise price payable for such shares.  Such cash
         distribution shall be paid within five (5) days following the option
         surrender date.

                             (iii)         The Plan Administrator shall, at the
         time the option with such limited stock appreciation right is granted
         under the Discretionary Option Grant Program, pre-approve any
         subsequent exercise of that right in accordance with the terms of this
         Paragraph C.  Accordingly, no further approval of the Plan
         Administrator or the Board shall be required at the time of the actual
         option surrender and cash distribution.

                              (iv)         The balance of the option (if any)
         shall remain outstanding and exercisable in accordance with the
         documents evidencing such option.

                                 ARTICLE THREE

                     SALARY INVESTMENT OPTION GRANT PROGRAM

       I.        OPTION GRANTS

                 The Primary Committee shall have the sole and exclusive
authority to determine the calendar year or years (if any) for which the Salary
Investment Option Grant Program is to be in effect and to select the Section 16
Insiders and other highly compensated Employees eligible to participate in the
Salary Investment Option Grant Program for such calendar year or years.  Each
selected individual who elects to participate in the Salary Investment Option
Grant Program must, prior to the start of each calendar year of participation,
file with the Plan Administrator (or its designate) an irrevocable
authorization directing the Corporation to reduce his or her base salary for
that calendar year by an amount not less than Ten Thousand Dollars ($10,000.00)
nor more than Fifty Thousand Dollars ($50,000.00).  The Primary Committee shall
have complete discretion to determine whether to approve the filed
authorization in whole or in part.  To the extent the Primary Committee
approves the authorization, the individual who filed that authorization shall
automatically be granted an option under the Salary Investment Grant Program on
the first trading day in January of the calendar year for which the salary
reduction is to be in effect.

     II.         OPTION TERMS

                 Each option shall be a Non-Statutory Option evidenced by one
or more documents in the form approved by the Plan Administrator; provided,
however, that each such document shall comply with the terms specified below.

                 A.       EXERCISE PRICE.

                          1.      The exercise price per share shall be
thirty-three and one-third percent (33-1/3%) of the Fair Market Value per share
of Common Stock on the option grant date.

                          2.      The exercise price shall become immediately
due upon exercise of the option and shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made
on the Exercise Date.

                 B.       NUMBER OF OPTION SHARES.  The number of shares of
Common Stock subject to the option shall be determined pursuant to the
following formula (rounded down to the nearest whole number):





                                      14.
<PAGE>   15
                          X = A / (B x 66-2/3%), where

                          X is the number of option shares,

                          A is the dollar amount of the approved reduction in
                          the Optionee's base salary for the calendar year, and

                          B is the Fair Market Value per share of Common Stock
                          on the option grant date.

                 C.       EXERCISE AND TERM OF OPTIONS.  The option shall
become exercisable in a series of twelve (12) successive equal monthly
installments upon the Optionee's completion of each calendar month of Service
in the calendar year for which the salary reduction is in effect.  Each option
shall have a maximum term of ten (10) years measured from the option grant
date.

                 D.       EFFECT OF TERMINATION OF SERVICE.  Should the
Optionee cease Service for any reason while holding one or more options under
this Article Three, then each such option shall remain exercisable, for any or
all of the shares for which the option is exercisable at the time of such
cessation of Service, until the earlier of (i) the expiration of the ten
(10)-year option term or (ii) the expiration of the three (3)-year period
measured from the date of such cessation of Service.  Should the Optionee die
while holding one or more options under this Article Three, then each such
option may be exercised, for any or all of the shares for which the option is
exercisable at the time of the Optionee's cessation of Service (less any shares
subsequently purchased by Optionee prior to death), by the personal
representative of the Optionee's estate or by the person or persons to whom the
option is transferred pursuant to the Optionee's will or in accordance with the
laws of descent and distribution.  Such right of exercise shall lapse, and the
option shall terminate, upon the earlier of (i) the expiration of the ten
(10)-year option term or (ii) the three (3)- year period measured from the date
of the Optionee's cessation of Service.  However, the option shall, immediately
upon the Optionee's cessation of Service for any reason, terminate and cease to
remain outstanding with respect to any and all shares of Common Stock for which
the option is not otherwise at that time exercisable.

     III .       CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

                 A.       In the event of any Corporate Transaction while the
Optionee remains in Service, each outstanding option held by such Optionee
under this Salary Investment Option Grant Program shall automatically
accelerate so that each such option shall, immediately prior to the effective
date of the Corporate Transaction, become fully exercisable with respect to the
total number of shares of Common Stock at the time subject to such option and
may be exercised for any or all of those shares as fully-vested shares of
Common Stock.  Each such outstanding option shall be assumed by the successor
corporation (or parent thereof) in the Corporate





                                      15.

Transaction and shall remain exercisable for the fully-vested shares until the
earlier of (i) the expiration of the ten (10)-year option term or (ii) the
expiration of the three (3)-year period measured from the date of the
Optionee's cessation of Service.

                 B.       In the event of a Change in Control while the
Optionee remains in Service, each outstanding option held by such Optionee
under this Salary Investment Option Grant Program shall automatically
accelerate so that each such option shall immediately become fully exercisable
with respect to the total number of shares of Common Stock at the time subject
to such option and may be exercised for any or all of those shares as
fully-vested shares of Common Stock.  The option shall remain so exercisable
until the earlier of (i) the expiration of the ten (10)-year option term, (ii)
the expiration of the three (3)-year period measured from the date of the
Optionee's cessation of Service or (iii) the surrender of the option in
connection with a Hostile Take-Over.

                 C.       Upon the occurrence of a Hostile Take-Over, the
Optionee shall have a thirty (30)-day period in which to surrender to the
Corporation each outstanding option granted him or her under the Salary
Investment Option Grant Program.  The Optionee shall in return be entitled to a
cash distribution from the Corporation in an amount equal to the excess of (i)
the Take-Over Price of the shares of Common Stock at the time subject to the
surrendered option (whether or not the Optionee is otherwise at the time vested
in those shares) over (ii) the aggregate exercise price payable for such
shares.  Such cash distribution shall be paid within five (5) days following
the surrender of the option to the Corporation.  The Primary Committee shall,
at the time the option with such limited stock appreciation right is granted
under the Salary Investment Option Grant Program, pre-approve any subsequent
exercise of that right in accordance with the terms of this Paragraph C.
Accordingly, no further approval of the Primary Committee or the Board shall be
required at the time of the actual option surrender and cash distribution.

                 D.       The grant of options under the Salary Investment
Option Grant Program shall in no way affect the right of the Corporation to
adjust, reclassify, reorganize or otherwise change its capital or business
structure or to merge, consolidate, dissolve, liquidate or sell or transfer all
or any part of its business or assets.

     III.        REMAINING TERMS

                 The remaining terms of each option granted under the Salary
Investment Option Grant Program shall be the same as the terms in effect for
option grants made under the Discretionary Option Grant Program.

                             STOCK ISSUANCE PROGRAM

       I.        STOCK ISSUANCE TERMS

                 Shares of Common Stock may be issued under the Stock Issuance
Program through direct and immediate issuances without any intervening option
grants.  Each such stock issuance shall be evidenced by a Stock Issuance
Agreement which complies with the terms specified below.  Shares of Common
Stock may also be issued under the Stock Issuance Program pursuant to share
right awards which entitle the recipients to receive those shares upon the
attainment of designated performance goals.

                 A.       PURCHASE PRICE.

                          1.      The purchase price per share shall be fixed
by the Plan Administrator, but shall not be less than one hundred percent
(100%) of the Fair Market Value per share of Common Stock on the issuance date.

                          2.      Subject to the provisions of Section I of
Article Seven, shares of Common Stock may be issued under the Stock Issuance
Program for any of the following items of consideration which the Plan
Administrator may deem appropriate in each individual instance:

                               (i)         cash or check made payable to the
         Corporation, or

                              (ii)         past services rendered to the
         Corporation (or any Parent or Subsidiary).

                 B.       VESTING PROVISIONS.

                          1.      The Plan Administrator may issue shares of
Common Stock under the Stock Issuance Program which are fully and immediately
vested upon issuance or which are to vest in one or more installments over the
Participant's period of Service or upon attainment of specified performance
objectives.  Alternatively, the Plan Administrator may issue share right awards
under the Stock Issuance Program which shall entitle the recipient to receive a
specified number of shares of Common Stock upon the attainment of one or more
performance goals established by the Plan Administrator.  Upon the attainment
of such performance goals, fully-vested shares of Common Stock shall be issued
in satisfaction of those share right awards.

                          2.      Any new, substituted or additional securities
or other property (including money paid other than as a regular cash dividend)
which the Participant may have the right to receive with respect to the
Participant's unvested shares of Common Stock by reason of any stock dividend,
stock split, recapitalization, combination of shares, exchange of shares or





                                      17.
<PAGE>   18
other change affecting the outstanding Common Stock as a class without the
Corporation's receipt of consideration shall be issued subject to (i) the same
vesting requirements applicable to the Participant's unvested shares of Common
Stock and (ii) such escrow arrangements as the Plan Administrator shall deem
appropriate.

                          3.      The Participant shall have full stockholder
rights with respect to any shares of Common Stock issued to the Participant
under the Stock Issuance Program, whether or not the Participant's interest in
those shares is vested.  Accordingly, the Participant shall have the right to
vote such shares and to receive any regular cash dividends paid on such shares.

                          4.      Should the Participant cease to remain in
Service while holding one or more unvested shares of Common Stock issued under
the Stock Issuance Program or should the performance objectives not be attained
with respect to one or more such unvested shares of Common Stock, then those
shares shall be immediately surrendered to the Corporation for cancellation,
and the Participant shall have no further stockholder rights with respect to
those shares.  To the extent the surrendered shares were previously issued to
the Participant for consideration paid in cash or cash equivalent (including
the Participant's purchase-money indebtedness), the Corporation shall repay to
the Participant the cash consideration paid for the surrendered shares and
shall cancel the unpaid principal balance of any outstanding purchase-money
note of the Participant attributable to the surrendered shares.

                          5.      The Plan Administrator may in its discretion
waive the surrender and cancellation of one or more unvested shares of Common
Stock which would otherwise occur upon the cessation of the Participant's
Service or the non-attainment of the performance objectives applicable to those
shares.  Such waiver shall result in the immediate vesting of the Participant's
interest in the shares of Common Stock as to which the waiver applies.  Such
waiver may be effected at any time, whether before or after the Participant's
cessation of Service or the attainment or non-attainment of the applicable
performance objectives.

                          6.      Outstanding share right awards under the
Stock Issuance Program shall automatically terminate, and no shares of Common
Stock shall actually be issued in satisfaction of those awards, if the
performance goals established for such awards are not attained.  The Plan
Administrator, however, shall have the discretionary authority to issue shares
of Common Stock in satisfaction of one or more outstanding share right awards
as to which the designated performance goals are not attained.

     II.         CORPORATE TRANSACTION/CHANGE IN CONTROL

                 A.       All of the Corporation's outstanding repurchase
rights under the Stock Issuance Program shall terminate automatically, and all
the shares of Common Stock subject to those terminated rights shall immediately
vest in full, in the event of any Corporate Transaction, except to the extent
(i) those repurchase rights are to be assigned to the successor corporation (or





                                      18.
<PAGE>   19
parent thereof) in connection with such Corporate Transaction or (ii) such
accelerated vesting is precluded by other limitations imposed in the Stock
Issuance Agreement.

                 B.       The Plan Administrator shall have the discretionary
authority, exercisable either at the time the unvested shares are issued or any
time while the Corporation's repurchase rights remain outstanding under the
Stock Issuance Program, to provide that those rights shall automatically
terminate in whole or in part, and the shares of Common Stock subject to those
terminated rights shall immediately vest, in the event the Participant's
Service should subsequently terminate by reason of an Involuntary Termination
within a designated period (not to exceed eighteen (18) months) following the
effective date of any Corporate Transaction in which those repurchase rights
are assigned to the successor corporation (or parent thereof).

                 C.       The Plan Administrator shall have the discretionary
authority, exercisable either at the time the unvested shares are issued or any
time while the Corporation's repurchase rights remain outstanding under the
Stock Issuance Program, to provide that those rights shall automatically
terminate in whole or in part, and the shares of Common Stock subject to those
terminated rights shall immediately vest, in the event the Participant's
Service should subsequently terminate by reason of an Involuntary Termination
within a designated period (not to exceed eighteen (18) months) following the
effective date of any Change in Control.

     III.        SHARE ESCROW/LEGENDS

                 Unvested shares may, in the Plan Administrator's discretion,
be held in escrow by the Corporation until the Participant's interest in such
shares vests or may be issued directly to the Participant with restrictive
legends on the certificates evidencing those unvested shares.

                         AUTOMATIC OPTION GRANT PROGRAM

       I .       OPTION TERMS

                 A.       GRANT DATES.  Option grants shall be made on the
dates specified below:

                          1.      Each individual who is first elected or
appointed as a non-employee Board member at any time on or after the
Underwriting Date shall automatically be granted, on the date of such initial
election or appointment, a Non-Statutory Option to purchase 15,000 shares of
Common Stock, provided that individual has not previously been in the employ of
the Corporation or any Parent or Subsidiary.

                          2.      On the date of each Annual Stockholders
Meeting held after the Underwriting Date, each individual who is to continue to
serve as an Eligible Director, whether or not that individual is standing for
re-election to the Board at that particular Annual Meeting, shall
automatically be granted a Non-Statutory Option to purchase 3,000 shares of
Common Stock, provided such individual has served as a non-employee Board
member for at least six (6) months.  There shall be no limit on the number of
such annual option grants any one Eligible Director may receive over his or her
period of Board service, and non-employee Board members who have previously
been in the employ of the Corporation (or any Parent or Subsidiary) or who
first joined the Board prior to the Underwriting Date shall be eligible to
receive one or more such annual option grants over their period of continued
Board service.

                 B.       EXERCISE PRICE.

                          1.      The exercise price per share shall be equal
to one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

                          2.      The exercise price shall be payable in one or
more of the alternative forms authorized under the Discretionary Option Grant
Program.  Except to the extent the sale and remittance procedure specified
thereunder is utilized, payment of the exercise price for the purchased shares
must be made on the Exercise Date.

                 C.       OPTION TERM.  Each option shall have a term of ten
(10) years measured from the option grant date.

                 D.       EXERCISE AND VESTING OF OPTIONS.  Each option shall
be immediately exercisable for any or all of the option shares.  However, any
shares purchased under the option shall be subject to repurchase by the
Corporation, at the exercise price paid per share, upon the Optionee's
cessation of Board service prior to vesting in those shares.  The shares
subject to each initial 15,000 share option grant shall vest, and the
Corporation's repurchase right shall lapse with





                                      20.
<PAGE>   21
respect to those shares, as follows: (i) twenty-five percent (25%) upon
Optionee's completion of one (1) year of Board service measured from the grant
date and (ii) the balance in a series of thirty-six (36) successive equal
monthly installments upon the Optionee's completion of each additional month of
Board service over the thirty-six (36)-month period measured from the first
anniversary of the option grant date.  The shares subject to each annual
3,000-share option grant shall vest, and the Corporation's repurchase right
shall lapse with respect to those shares, upon the Optionee's completion of one
(1) year of Board service measured from the grant date.

                 E.       TERMINATION OF BOARD SERVICE.  The following
provisions shall govern the exercise of any options held by the Optionee at the
time the Optionee ceases to serve as a Board member:

                               (i)         The Optionee (or, in the event of
         Optionee's death, the personal representative of the Optionee's estate
         or the person or persons to whom the option is transferred pursuant to
         the Optionee's will or in accordance with the laws of descent and
         distribution) shall have a twelve (12)-month period following the date
         of such cessation of Board service in which to exercise each such
         option.

                              (ii)         During the twelve (12)-month
         exercise period, the option may not be exercised in the aggregate for
         more than the number of vested shares of Common Stock for which the
         option is exercisable at the time of the Optionee's cessation of Board
         service.

                             (iii)         Should the Optionee cease to serve
         as a Board member by reason of death or Permanent Disability, then all
         shares at the time subject to the option shall immediately vest so
         that such option may, during the twelve (12)-month exercise period
         following such cessation of Board service, be exercised for all or any
         portion of those shares as fully-vested shares of Common Stock.

                              (iv)         In no event shall the option remain
         exercisable after the expiration of the option term.  Upon the
         expiration of the twelve (12)-month exercise period or (if earlier)
         upon the expiration of the option term, the option shall terminate and
         cease to be outstanding for any vested shares for which the option has
         not been exercised.  However, the option shall, immediately upon the
         Optionee's cessation of Board service for any reason other than death
         or Permanent Disability, terminate and cease to be outstanding to the
         extent the option is not otherwise at that time exercisable for vested
         shares.

       II.       CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

                 F.       In the event of any Corporate Transaction, the shares
of Common Stock at the time subject to each outstanding option but not
otherwise vested shall automatically vest in full so that each such option
shall, immediately prior to the effective date of the Corporate Transaction,
become fully exercisable for all of those Option Shares as fully-vested shares
of Common Stock and may be exercised for all or any portion of those vested
shares.  Immediately following the consummation of the Corporate Transaction,
each automatic option grant shall terminate and cease to be outstanding, except
to the extent assumed by the successor corporation (or parent thereof).

                 G.       In connection with any Change in Control, the shares
of Common Stock at the time subject to each outstanding option but not
otherwise vested shall automatically vest in full so that each such option
shall, immediately prior to the effective date of the Change in Control, become
fully exercisable for all of those Option Shares as fully-vested shares of
Common Stock and may be exercised for all or any portion of those vested
shares.  Each such option shall remain exercisable for such fully-vested option
shares until the expiration or sooner termination of the option term or the
surrender of the option in connection with a Hostile Take-Over.

                 H.       All outstanding repurchase rights shall automatically
terminate, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Corporate Transaction or
Change in Control.

                 I.       Upon the occurrence of a Hostile Take-Over, the
Optionee shall have a thirty (30)-day period in which to surrender to the
Corporation each of his or her outstanding automatic option grants.  The
Optionee shall in return be entitled to a cash distribution from the
Corporation in an amount equal to the excess of (i) the Take-Over Price of the
shares of Common Stock at the time subject to each surrendered option (whether
or not the Optionee is otherwise at the time vested in those shares) over (ii)
the aggregate exercise price payable for such shares.  Such cash distribution
shall be paid within five (5) days following the surrender of the option to the
Corporation.  No approval or consent of the Board or any Plan Administrator
shall be required in connection with such option surrender and cash
distribution.

                 J.       Each option which is assumed in connection with a
Corporate Transaction shall be appropriately adjusted, immediately after such
Corporate Transaction, to apply to the number and class of securities which
would have been issuable to the Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction.  Appropriate adjustments shall also be made to the exercise price
payable per share under each outstanding option, provided the aggregate
exercise price payable for such securities shall remain the same.

<PAGE>   23
                 K.       The grant of options under the Automatic Option Grant
Program shall in no way affect the right of the Corporation to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

     III .       REMAINING TERMS

                 The remaining terms of each option granted under the Automatic
Option Grant Program shall be the same as the terms in effect for option grants
made under the Discretionary Option Grant Program.

                       DIRECTOR FEE OPTION GRANT PROGRAM


       I.        OPTION GRANTS

                 The Plan Administrator shall have the sole and exclusive
authority to determine the calendar year or years (if any) the Director Fee
Option Grant Program is to be in effect.  Once the Director Fee Option Grant
Program is in effect, each non-employee Board member may elect to apply all or
any portion of the annual retainer fee otherwise payable in cash for his or her
service on the Board to the acquisition of a special option grant under this
Director Fee Option Grant Program.  Such election must be filed with the
Corporation's Chief Financial Officer prior to first day of the calendar year
for which the annual retainer fee which is the subject of that election is
otherwise payable.  Each non-employee Board member who files such a timely
election shall automatically be granted an option under this Director Fee
Option Grant Program on the first trading day in January in the calendar year
for which the annual retainer fee which is the subject of that election would
otherwise be payable in cash.

     II.         OPTION TERMS

                 Each option shall be a Non-Statutory Option governed by the
terms and conditions specified below.

                 A.       EXERCISE PRICE.

                          1.      The exercise price per share shall be
thirty-three and one-third percent (33-1/3%) of the Fair Market Value per share
of Common Stock on the option grant date.

                          2.      The exercise price shall become immediately
due upon exercise of the option and shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made
on the Exercise Date.

                 B.       NUMBER OF OPTION SHARES.  The number of shares of
Common Stock subject to the option shall be determined pursuant to the
following formula (rounded down to the nearest whole number):

                          X = A / (B x 66-2/3%), where

                          X is the number of option shares,





                                      24.
<PAGE>   25
                          A is the portion of the annual retainer fee subject
                          to the non-employee Board member's election, and

                          B is the Fair Market Value per share of Common Stock
                          on the option grant date.

                 C.       EXERCISE AND TERM OF OPTIONS.  The option shall
become exercisable in a series of twelve (12) equal monthly installments upon
the Optionee's completion of each month of Board service over the twelve
(12)-month period measured from the grant date.  Each option shall have a
maximum term of ten (10) years measured from the option grant date.

                 D.       TERMINATION OF BOARD SERVICE.  Should the Optionee
cease Board service for any reason (other than death or Permanent Disability)
while holding one or more options under this Director Fee Option Grant Program,
then each such option shall remain exercisable, for any or all of the shares
for which the option is exercisable at the time of such cessation of Board
service, until the earlier of (i) the expiration of the ten (10)-year option
term or (ii) the expiration of the three (3)-year period measured from the date
of such cessation of Board service.  However, each option held by the Optionee
under this Director Fee Option Grant Program at the time of his or her
cessation of Board service shall immediately terminate and cease to remain
outstanding with respect to any and all shares of Common Stock for which the
option is not otherwise at that time exercisable.

                 E.       DEATH OR PERMANENT DISABILITY.  Should the Optionee's
service as a Board member cease by reason of death or Permanent Disability,
then each option held by such Optionee under this Director Fee Option Grant
Program shall immediately become exercisable for all the shares of Common Stock
at the time subject to that option, and the option may be exercised for any or
all of those shares as fully-vested shares until the earlier of (i) the
expiration of the ten (10)-year option term or (ii) the expiration of the three
(3)-year period measured from the date of such cessation of Board service.

                 Should the Optionee die after cessation of Board service but
while holding one or more options under this Director Fee Option Grant Program,
then each such option may be exercised, for any or all of the shares for which
the option is exercisable at the time of the Optionee's cessation of Board
service (less any shares subsequently purchased by Optionee prior to death), by
the personal representative of the Optionee's estate or by the person or
persons to whom the option is transferred pursuant to the Optionee's will or in
accordance with the laws of descent and distribution.  Such right of exercise
shall lapse, and the option shall terminate, upon the earlier of (i) the
expiration of the ten (10)-year option term or (ii) the three (3)-year period
measured from the date of the Optionee's cessation of Board service.

     III.        CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

                 A.       In the event of any Corporate Transaction while the
Optionee remains a Board member, each outstanding option held by such Optionee
under this Director Fee Option Grant Program shall automatically accelerate so
that each such option shall, immediately prior to the effective date of the
Corporate Transaction, become fully exercisable with respect to the total
number of shares of Common Stock at the time subject to such option and may be
exercised for any or all of those shares as fully-vested shares of Common
Stock.  Each such outstanding option shall be assumed by the successor
corporation (or parent thereof) in the Corporate Transaction and shall remain
exercisable for the fully-vested shares until the earlier of (i) the expiration
of the ten (10)-year option term or (ii) the expiration of the three (3)-year
period measured from the date of the Optionee's cessation of Board service.

                 B.       In the event of a Change in Control while the
Optionee remains in Service, each outstanding option held by such Optionee
under this Director Fee Option Grant Program shall automatically accelerate so

       I.        FINANCING

                 The Plan Administrator may permit any Optionee or Participant
to pay the option exercise price under the Discretionary Option Grant Program
or the purchase price of shares issued under the Stock Issuance Program by
delivering a full-recourse, interest bearing promissory note payable in one or
more installments.  The terms of any such promissory note (including the
interest rate and the terms of repayment) shall be established by the Plan
Administrator in its sole discretion.  In no event may the maximum credit
available to the Optionee or Participant exceed the sum of (i) the aggregate
option exercise price or purchase price payable for the purchased shares plus
(ii) any Federal, state and local income and employment tax liability incurred
by the Optionee or the Participant in connection with the option exercise or
share purchase.

     II.         TAX WITHHOLDING

                 A.       The Corporation's obligation to deliver shares of
Common Stock upon the exercise of options or the issuance or vesting of such
shares under the Plan shall be subject to the satisfaction of all applicable
Federal, state and local income and employment tax withholding requirements.

                 B.       The Plan Administrator may, in its discretion,
provide any or all holders of Non-Statutory Options or unvested shares of
Common Stock under the Plan (other than the options granted or the shares
issued under the Automatic Option Grant or Director Fee Option Grant Program)
with the right to use shares of Common Stock in satisfaction of all or part of
the Taxes incurred by such holders in connection with the exercise of their
options or the vesting of their shares.  Such right may be provided to any such
holder in either or both of the following formats:

                          Stock Withholding:  The election to have the
Corporation withhold, from the shares of Common Stock otherwise issuable upon
the exercise of such Non-Statutory Option or the vesting of such shares, a
portion of those shares with an aggregate Fair Market Value equal to the
percentage of the Taxes (not to exceed one hundred percent (100%)) designated
by the holder.

                          Stock Delivery:  The election to deliver to the
Corporation, at the time the Non-Statutory Option is exercised or the shares
vest, one or more shares of Common Stock previously acquired by such holder
(other than in connection with the option exercise or share vesting triggering
the Taxes) with an aggregate Fair Market Value equal to the percentage of the
Taxes (not to exceed one hundred percent (100%)) designated by the holder.

     III.        EFFECTIVE DATE AND TERM OF THE PLAN

                 A.       The Discretionary Option Grant, Stock Issuance and
Automatic Option Grant Programs shall become effective on the Underwriting
Date.  The Salary Investment Option Grant Program and the Director Fee Option
Grant Program shall not be implemented until such time as the Primary Committee
may deem appropriate.  Options may be granted under the Discretionary Option
Grant or Automatic Option Grant Program at any time on or after the
Underwriting Date.  However, no options granted under the Plan may be
exercised, and no shares shall be issued under the Plan, until the Plan is
approved by the Corporation's stockholders.  If such stockholder approval is
not obtained within twelve (12) months after the Plan Effective Time, then all
options previously granted under this Plan shall terminate and cease to be
outstanding, and no further options shall be granted and no shares shall be
issued under the Plan.

                 B.       The Plan shall serve as the successor to the
Predecessor Plan, and no further option grants or direct stock issuances shall
be made under the Predecessor Plan after the Section 12 Registration Date.
All options outstanding under the Predecessor Plan on the Section 12
Registration Date shall be incorporated into the Plan at that time and shall be
treated as outstanding options under the Plan.  However, each outstanding
option so incorporated shall continue to be governed solely by the terms of the
documents evidencing such option, and no provision of the Plan shall be deemed
to affect or otherwise modify the rights or obligations of the holders of such
incorporated options with respect to their acquisition of shares of Common
Stock.

                 C.       One or more provisions of the Plan, including
(without limitation) the option/vesting acceleration provisions of Article Two
relating to Corporate Transactions and Changes in Control, may, in the Plan
Administrator's discretion, be extended to one or more options incorporated
from the Predecessor Plan which do not otherwise contain such provisions.

                 D.       The Plan shall terminate upon the earliest to occur
of (i) April 30, 2008 (ii) the date on which all shares available for issuance
under the Plan shall have been issued as fully-vested shares or (iii) the
termination of all outstanding options in connection with a Corporate
Transaction.  Should the Plan terminate on April 30, 2008, then all option
grants and unvested stock issuances outstanding at that time shall continue to
have force and effect in accordance with the provisions of the documents
evidencing such grants or issuances.

     IV.         AMENDMENT OF THE PLAN

                 A.       The Board shall have complete and exclusive power and
authority to amend or modify the Plan in any or all respects.  However, no such
amendment or modification shall adversely affect the rights and obligations
with respect to stock options or unvested stock issuances at the time
outstanding under the Plan unless the Optionee or the Participant consents to
such amendment or modification.  In addition, certain amendments may require
stockholder approval pursuant to applicable laws or regulations.

<PAGE>   30
                 B.       Options to purchase shares of Common Stock may be
granted under the Discretionary Option Grant and Salary Investment Option Grant
Programs and shares of Common Stock may be issued under the Stock Issuance
Program that are in each instance in excess of the number of shares then
available for issuance under the Plan, provided any excess shares actually
issued under those programs shall be held in escrow until there is obtained
stockholder approval of an amendment sufficiently increasing the number of
shares of Common Stock available for issuance under the Plan.  If such
stockholder approval is not obtained within twelve (12) months after the date
the first such excess issuances are made, then (i) any unexercised options
granted on the basis of such excess shares shall terminate and cease to be
outstanding and (ii) the Corporation shall promptly refund to the Optionees and
the Participants the exercise or purchase price paid for any excess shares
issued under the Plan and held in escrow, together with interest (at the
applicable Short Term Federal Rate) for the period the shares were held in
escrow, and such shares shall thereupon be automatically cancelled and cease to
be outstanding.

       V.        USE OF PROCEEDS

                 Any cash proceeds received by the Corporation from the sale of
shares of Common Stock under the Plan shall be used for general corporate
purposes.

     VI.         REGULATORY APPROVALS

                 A.       The implementation of the Plan, the granting of any
stock option under the Plan and the issuance of any shares of Common Stock (i)
upon the exercise of any granted option or (ii) under the Stock Issuance
Program shall be subject to the Corporation's procurement of all approvals and
permits required by regulatory authorities having jurisdiction over the Plan,
the stock options granted under it and the shares of Common Stock issued
pursuant to it.

                 B.       No shares of Common Stock or other assets shall be
issued or delivered under the Plan unless and until there shall have been
compliance with all applicable requirements of Federal and state securities
laws, including the filing and effectiveness of the Form S-8 registration
statement for the shares of Common Stock issuable under the Plan, and all
applicable listing requirements of any stock exchange (or the Nasdaq National
Market, if applicable) on which Common Stock is then listed for trading.

     VII.        NO EMPLOYMENT/SERVICE RIGHTS

                 Nothing in the Plan shall confer upon the Optionee or the
Participant any right to continue in Service for any period of specific
duration or interfere with or otherwise restrict in any way the rights of the
Corporation (or any Parent or Subsidiary employing or retaining such person) or
of the Optionee or the Participant, which rights are hereby expressly reserved
by each, to terminate such person's Service at any time for any reason, with or
without cause.

other special payments, commissions and other marketing incentive payments.

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

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

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


                  ARTICLE III - ELIGIBILITY AND PARTICIPATION

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

         3.2.  LEAVE OF ABSENCE.  For purposes of participation in the Plan, a
person on leave of absence shall be deemed to be an employee for the first 90
days of such leave of absence and such employee's employment shall be deemed to
have terminated (for purposes of this Plan only) at the close of business on
the 90th day of such leave of absence unless such employee shall have returned
to regular full-time or part-time employment (as the case may be) prior to the
close of business on such 90th day.  Termination by the Company of any
employee's leave of absence,
<PAGE>   2
other than termination of such leave of absence on return to full-time or
part-time employment, shall terminate an employee's employment for all purposes
of the Plan and shall terminate such employee's participation in the Plan and
right to exercise any option.

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

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

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

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


                             ARTICLE IV - OFFERINGS

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

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

                         ARTICLE V - PAYROLL DEDUCTIONS

         5.1.  AMOUNT OF DEDUCTION.  At the time a participant files his
authorization for payroll





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

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

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

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


                        ARTICLE VI - GRANTING OF OPTION

         6.1.  NUMBER OF OPTION SHARES.  On each Offering Commencement Date, a
participating employee shall be deemed to have been granted an option to
purchase a maximum number of shares of the Common Stock of the Company equal to
an amount determined as follows: an amount equal to (i) that percentage of the
employee's Base Pay which he has elected to have withheld (but not in any case
in excess of 10%) multiplied by (ii) the employee's Base Pay on the Offering
Commencement Date divided by (iii) 85% of the market value of the Common Stock
of the Company on the Offering Commencement Date or Offering Termination Date
(as determined pursuant to Section 6.2, below).  The market value of the
Company's stock shall be determined as provided in paragraphs (a) and (b) of
Section  6.2 below.  An employee's Base Pay during the period of an offering
shall be determined by multiplying his normal monthly rate of pay (as in effect
on the Offering Commencement Date) by 6, or the hourly rate by 1040, as the
case may be, provided that, in the case of a part time hourly employee, the
employee's Base Pay during the period of an Offering shall be determined by
multiplying such employee's hourly rate by the number of regularly scheduled
hours of work for such employee during such Offering.  An employee's Base Pay
during the Offering with the Offering Commencement Date of November 1, 1995
shall be determined by multiplying his normal monthly rate of pay (as
determined on the Offering Commencement Date) by 8, or the hourly rate by 1387.





                                      -3-
<PAGE>   4
         6.2.  OPTION PRICE.  The option price of Common Stock purchased with
payroll deductions made during an Offering for a participant therein shall be
the lower of:

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

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


                        ARTICLE VII - EXERCISE OF OPTION

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

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

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

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

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


                           ARTICLE VIII - WITHDRAWAL

         8.1.  IN GENERAL.  As indicated in Section  7.2, a participant may
withdraw payroll deductions credited to his account under the Plan at any time
by giving written notice to the Plan Administrator.  All of





                                      -4-
<PAGE>   5
the participant's payroll deductions credited to his account will be paid to
him promptly after receipt of his notice of withdrawal, and no further payroll
deductions will be made from his pay during such Offering.  The Company may, at
its option, treat any attempt to borrow by an employee on the security of his
accumulated payroll deductions as an election, under Section  3.2, to withdraw
such deductions.

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

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

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

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

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

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

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

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

                 (b)      To exercise the participant's option for the purchase
of stock on the Offering Termination Date next following the date of the
participant's retirement for the purchase





                                      -5-
<PAGE>   6
of the number of full shares of stock which the accumulated payroll deductions
in the participant's account at the date of the participant's retirement will
purchase at the applicable option price, and any excess in such account will be
returned to the participant, without interest.

In the event that no such written notice of election shall be duly received by
the Plan Administrator, the participant shall automatically be deemed to have
elected to withdraw all payroll deductions pursuant to paragraph (a), above.

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


                             ARTICLE IX - INTEREST

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


                               ARTICLE X - STOCK

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

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

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





                                      -6-
<PAGE>   7
with rights of survivorship or as tenants by the entireties, to the extent
permitted by applicable law.

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

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

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


                          ARTICLE XI - ADMINISTRATION

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

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

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

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

                          ARTICLE XII - MISCELLANEOUS

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

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

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

         12.4.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.

                 (a)      If, while any options are outstanding, the
outstanding shares of Common Stock of the Company have increased, decreased,
changed into, or been exchanged for a different number or kind of shares or
securities of the Company through reorganization, recapitalization,
reclassification, stock split, reverse stock split or similar transaction,
appropriate and proportionate adjustments may be made by the Committee in the
number and/or kind of shares which are subject to purchase under outstanding
options and on the option exercise price or prices applicable to such
outstanding options.  In addition, in any such event, the number and/or kind of
shares which may be offered in the Offerings described in Article IV hereof
shall also be proportionately adjusted.  No adjustments shall be made for stock
dividends.  For the purposes of this paragraph, any distribution of shares to
shareholders in an amount aggregating 20% or more of the outstanding shares
shall be deemed a stock split and any distributions of shares aggregating less
than 20% of the outstanding shares shall be deemed a stock dividend.

                 (b)      Upon the dissolution or liquidation of the Company,
or upon a





                                      -8-
<PAGE>   9
reorganization, merger or consolidation of the Company with one or more
corporations as a result of which the Company is not the surviving corporation,
or upon a reorganization, merger or consolidation of the Company with one or
more corporations as a result of which the holders of the Corporation's capital
stock prior to such transaction hold less than 50% of the capital stock of the
entity surviving such transaction, or upon a sale of all or substantially all
of the property or stock of the Company to another corporation, the holder of
each option then outstanding (and for which payroll deductions have been made)
under the Plan will thereafter be entitled to receive at the next Offering
Termination Date upon the exercise of such option for each share as to which
such option shall be exercised, as nearly as reasonably may be determined, the
cash, securities and/or property which a holder of one share of the Common
Stock was entitled to receive upon and at the time of such transaction.  The
Board of Directors shall take such steps in connection with such transactions
as the Board shall deem necessary to assure that the provisions of this Section
12.4 shall thereafter be applicable, as nearly as reasonably may be determined,
in relation to the said cash, securities and/or property as to which such
holder of such option might thereafter be entitled to receive.

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

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

         12.7.  NO EMPLOYMENT RIGHTS.  The Plan does not, directly or
indirectly, create any right for the benefit of any employee or class of
employees to purchase any shares under the Plan, or create in any employee or
class of employees any right with respect to continuation of employment by the
Company, and it shall not be deemed to interfere in any way with the Company's
right to terminate, or otherwise modify, an employee's employment at any time.

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

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

         authorized by the Delaware General Corporation Law, as amended (the
         "DGCL");

         WHEREAS, the Bylaws, the Amended and Restated Certificate of
         Incorporation (the "Certificate of Incorporation") and the DGCL, by
         their non-exclusive nature, permit contracts between the Company and
         the members of its Board of Directors, officers, employees or agents
         with respect to indemnification of such directors, officers, employees
         or agents;

         WHEREAS, in accordance with the authorization as provided by the DGCL,
         the Company either has purchased and presently maintains or intends to
         purchase and maintain a policy or policies of Directors and Officers
         Liability Insurance ("D&O Insurance") covering certain liabilities
         which may be incurred by its directors and officers in the performance
         of their duties as directors and officers of the Company;

         WHEREAS, as a result of developments affecting the terms, scope and
         availability of D&O Insurance there exists general uncertainty as to
         the extent of protection afforded members of the Board of Directors or
         officers, employees or agents by such D&O Insurance and by statutory
         and bylaw indemnification provisions; and

         WHEREAS, in order to induce Indemnitee to continue to serve as a member
         of the Board of Directors, officer, employee or agent of the Company,
         the Company has determined and agreed to enter into this contract with
         Indemnitee.

         NOW, THEREFORE, in consideration of Indemnitee's continued service as a
director, officer, employee or agent after the date hereof, and for other good
and valid consideration, the receipt and adequacy of which is hereby
acknowledged, the parties hereto agree as follows:


<PAGE>   2

                  1. Indemnification of Indemnitee. The Company hereby agrees to
hold harmless and indemnify Indemnitee to the fullest extent authorized or
permitted by the provisions of the DGCL, as may be amended from time to time.

                  2. Additional Indemnity. Subject only to the exclusions set
forth in Sections 3 and 6(c) hereof, the Company hereby further agrees to hold
harmless and indemnify Indemnitee:

                     (a) Against any and all expenses (including attorneys'
fees), witness fees, judgments, fines and amounts paid in settlement actually
and reasonably incurred by Indemnitee in connection with any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (including an action by or in the right of the Company) to
which Indemnitee is, was or at any time becomes a party, or is threatened to be
made a party, by reason of the fact that Indemnitee is, was or at any time
becomes a director, officer, employee or agent of the Company or any subsidiary
of the Company, or is or was serving or at any time serves at the request of the
Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise;
and

                     (b) Otherwise to the fullest extent as may be provided to
Indemnitee by the Company under the non-exclusivity provisions of the Bylaws of
the Company, the Certificate of Incorporation and the DGCL.

                  3. Limitations on Additional Indemnity.

                     (a) No indemnity pursuant to Section 2 hereof shall be
paid by the Company:

                         i) In respect to remuneration paid to Indemnitee if
it shall be determined by a final judgment or other final adjudication that such
remuneration was in violation of law;

                         ii) On account of any suit in which judgment is
rendered against Indemnitee for an accounting of profits made from the purchase
or sale by Indemnitee of securities of the Company pursuant to the provisions of
Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto or
similar provisions of any federal, state or local statutory law;

                         iii) On account of Indemnitee's conduct which is
finally adjudged to have been knowingly fraudulent or deliberately dishonest or
to constitute willful misconduct;

                         iv) On account of Indemnitee's conduct which is the
subject of an action, suit or proceeding described in Section 6(c)(ii) hereof;


                                        2

<PAGE>   3

                         v) On account of any action, claim or proceeding
(other than a proceeding referred to in Section 7(b) hereof) initiated by the
Indemnitee unless such action, claim or proceeding was authorized in the
specific case by action of the Board of Directors;

                         vi) If a final decision by a Court having jurisdiction
in the matter shall determine that such indemnification is not lawful (and, in
this respect, both the Company and Indemnitee have been advised that the
Securities and Exchange Commission believes that indemnification for liabilities
arising under the federal securities laws is against public policy and is,
therefore, unenforceable and that claims for indemnification should be submitted
to appropriate courts for adjudication); and

                         vii) Except to the extent the aggregate of losses to
be indemnified thereunder exceeds the sum of (a) such losses for which the
Indemnitee is indemnified pursuant to Section 1 hereof and (b) any additional
amount paid to the Indemnitee pursuant to any D&O Insurance purchased and
maintained by the Company.

                     (b) No indemnity pursuant to Section 1 or 2 hereof shall
be paid by the Company if the action, suit or proceeding with respect to which a
claim for indemnity hereunder is made arose from or is based upon any of the
following:

                         i) Any solicitation of proxies by Indemnitee, or by a
group of which he was or became a member consisting of two or more persons that
had agreed (whether formally or informally and whether or not in writing) to act
together for the purpose of soliciting proxies, in opposition to any
solicitation of proxies approved by the Board of Directors.

                         ii) Any activities by Indemnitee that constitute a
breach of or default under any agreement between Indemnitee and the Company.

                  4. Contribution. If the indemnification provided in Sections 1
and 2 hereof is unavailable by reason of a Court decision described in Section
3(a)(vi) hereof based on grounds other than any of those set forth in paragraphs
(i) through (v) of Section 3 (a) hereof, then in respect of any threatened,
pending or completed action, suit or proceeding in which the Company is jointly
liable with Indemnitee (or would be if joined in such action, suit or
proceeding), the Company shall contribute to the amount of expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred and paid or payable by Indemnitee in such proportion as is
appropriate to reflect (i) the relative benefits received by the Company on the
one hand and Indemnitee on the other hand from the transaction from which such
action, suit or proceeding arose, and (ii) the relative fault of the Company on
the one hand and of Indemnitee on the other in connection with the events which
resulted in such expenses, judgments, fines or settlement amounts, as well as
any other relevant equitable considerations. The relative fault of the Company
on the one hand and of Indemnitee on the other shall be determined by reference
to, among other things, the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent the circumstances resulting in
such expenses,


                                        3

<PAGE>   4



judgments, fines or settlement amounts. The Company agrees that it would not be
just and equitable if contribution pursuant to this Section 4 were determined by
pro rata allocation or any other method of allocation which does not take
account of the foregoing equitable considerations.

                  5. Notification and Defense of Claim. Not later than thirty
(30) days after receipt by Indemnitee of notice of the commencement of any
action, suit or proceeding, Indemnitee shall, if a claim in respect thereof is
to be made against the Company under this Agreement, notify the President of the
Company of the commencement thereof; but Indemnitee's omission to notify the
Company will not relieve the Company from any liability which it may have to
Indemnitee otherwise than under this Agreement. The Company shall promptly
acknowledge the notice from the Indemnitee. With respect to any such action,
suit or proceeding as to which Indemnitee notifies the Company of the
commencement thereof:

                     (a) The Company will be entitled to participate therein at
its own expense.

                     (b) Except as otherwise provided below, to the extent that
it may wish, the Company shall, jointly with any other indemnifying party
similarly notified, be entitled to assume the defense thereof, with counsel
reasonably satisfactory to Indemnitee. After notice from the Company to
Indemnitee of its election to assume the defense thereof, the Company will not
be liable to Indemnitee under this Agreement for any legal or other expenses
subsequently incurred by Indemnitee in connection with the defense thereof,
other than reasonable costs of investigation or as otherwise provided below.
Indemnitee shall have the right to employ its own counsel in such action, suit
or proceeding, but the fees and expenses of such counsel incurred after notice
from the Company of the Company's assumption of the defense thereof shall be at
the expense of Indemnitee unless (i) the employment of counsel by Indemnitee has
been authorized by the Company; (ii) Indemnitee shall have reasonably concluded
that there may be a conflict of interest between the Company and Indemnitee in
the conduct of the defense of such action; or (iii) the Company shall not in
fact have employed counsel to assume the defense of such action; in each of
which cases the fees and expenses of Indemnitee's separate counsel shall be paid
by the Company. The Company shall not be entitled to assume the defense of any
action, suit or proceeding brought by or on behalf of the Company or as to which
Indemnitee shall have made the conclusion provided for in (ii) above.

                     (c) The Company shall not be liable to indemnify
Indemnitee under this Agreement for any amounts paid in settlement of any action
or claim effected without its written consent. The Company shall be permitted to
settle any action except that it shall not settle any action or claim in any
manner which would impose any penalty or limitation on Indemnitee without
Indemnitee's written consent. Neither the Company nor Indemnitee will
unreasonably withhold its consent to any proposed settlement.

                  6. Advancement and Repayment of Expenses.



                                        4

<PAGE>   5



                     (a) In the event that Indemnitee employs his or her own
counsel pursuant to Sections 5(b)(i) through (iii) above, the Company shall
advance to Indemnitee, prior to any final disposition of any threatened or
pending action, suit or proceeding, whether civil, criminal, administrative or
investigative, any and all reasonable expenses (including legal fees and
expenses) incurred in investigating or defending any such action, suit or
proceeding within ten (10) days after receiving from Indemnitee copies of
invoices presented to Indemnitee for such expenses.

                     (b) Indemnitee agrees that Indemnitee will reimburse the
Company for all reasonable expenses paid by the Company in investigating or
defending any civil or criminal action, suit or proceeding against Indemnitee in
the event and only to the extent it shall be ultimately determined by a final
judicial decision (from which there is no right of appeal) that Indemnitee is
not entitled, under the provisions of the DGCL, the Bylaws, this Agreement or
otherwise, to be indemnified by the Company for such expenses.

                     (c) Notwithstanding the foregoing, the Company shall not
be required to advance such expenses to Indemnitee in respect of any action
arising from or based upon any of the matters set forth in subsection (b) of
Section 3 or if Indemnitee (i) commences any action, suit or proceeding as a
plaintiff unless such advance is specifically approved by a majority of the
Board of Directors or (ii) is a party to an action, suit or proceeding brought
by the Company and approved by a majority of the Board which alleges willful
misappropriation of corporate assets by Indemnitee, disclosure of confidential
information in violation of Indemnitee's fiduciary or contractual obligations to
the Company, or any other willful and deliberate breach in bad faith of
Indemnitee's duty to the Company or its shareholders.

                  7. Enforcement.

                     (a) The Company expressly confirms and agrees that it has
entered into this Agreement and assumed the obligations imposed on the Company
hereby in order to induce Indemnitee to continue as a director, officer,
employee or other agent of the Company, and acknowledges that Indemnitee is
relying upon this Agreement in continuing in such capacity.

                     (b) In the event Indemnitee is required to bring any
action to enforce rights or to collect moneys due under this Agreement and is
successful in such action, the Company shall reimburse Indemnitee for all
Indemnitee's reasonable fees and expenses, including attorney's fees, in
bringing and pursuing such action.

                  8. Subrogation. In the event of payment under this agreement,
the Company shall be subrogated to the extent of such payment to all of the
rights of recovery of Indemnitee, who shall execute all documents required and
shall do all acts that may be necessary to secure such rights and to enable the
Company effectively to bring suit to enforce such rights.



                                        5

<PAGE>   6



                  9. Continuation of Obligations. All agreements and obligations
of the Company contained herein shall commence upon the date that Indemnitee
first became a member of the Board of Directors or an officer, employee or agent
of the Company, as the case may be, and shall continue during the period
Indemnitee is a director, officer, employee or agent of the Company (or is or
was serving at the request of the Company as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise) and shall continue thereafter so long as
Indemnitee shall be subject to any possible claim or threatened, pending or
completed action, suit or proceeding, whether civil, criminal or investigative,
by reason of the fact that Indemnitee was a director, officer, employee or agent
of the Company or serving in any other capacity referred to herein.

                  10. Survival of Rights. The rights conferred on Indemnitee by
this Agreement shall continue after Indemnitee has ceased to be a director,
officer, employee or other agent of the Company and shall inure to the benefit
of Indemnitee's heirs, executors and administrators.

                  11. Non-Exclusivity of Rights. The rights conferred on
Indemnitee by this Agreement shall not be exclusive of any other right which
Indemnitee may have or hereafter acquire under any statute, provision of the
Company's Certificate of Incorporation or Bylaws, agreement, vote of
stockholders or directors, or otherwise, both as to action in his official
capacity and as to action in another capacity while holding office; provided,
however, that this Agreement shall supersede and replace any prior
indemnification agreements entered into by and between the Company and
Indemnitee and that any such prior indemnification agreement shall be terminated
upon the execution of this Agreement.

                  12. Separability. Each of the provisions of this Agreement is
a separate and distinct agreement and independent of the others, so that if any
or all of the provisions hereof shall be held to be invalid or unenforceable for
any reason, such invalidity or unenforceability shall not affect the validity or
enforceability of the other provisions hereof or the obligation of the Company
to indemnify the Indemnitee to the full extent provided by the Bylaws or the
DGCL.

                  13. Governing Law. This Agreement shall be interpreted and
