                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and the Financial Statements and Notes thereto appearing elsewhere
in this Prospectus.
 
                                  THE COMPANY
 
   
     GeoTel Communications Corporation ("GeoTel" or the "Company") is a provider
of telecommunications software solutions focused on enhanced call routing
technology that enables customer-oriented companies to deliver responsive and
cost-effective customer service. The Company's software solutions are aimed at
decentralized or service-oriented corporations that use call centers, voice
response units and other answering resources to interact with their customers.
GeoTel's software solution, the Intelligent CallRouter, is designed for
companies that utilize multiple call centers to handle high volumes of inbound
customer calls and regard their effective handling of customer interaction
through call center technology as a key competitive advantage. The Company is
focused on open, standards-based software solutions for enterprise-wide call
distribution in a multi-vendor, multi-carrier, fault-tolerant, distributed
environment. GeoTel's call routing solutions have been deployed by a variety of
companies, including America Online, American Express, Fidelity, MCI, Matrixx
Marketing, Spiegel and USAir, representing approximately 6.5%, 2.6%, 23.3%,
7.0%, 4.9%, 3.8% and 6.7%, respectively, of the Company's total revenues to
date.
    
 
     Companies are increasingly recognizing that excellent customer service can
be used as a strategic weapon to differentiate their firms from competitors. In
order to remain competitive, corporations must continually evaluate their
product and service offerings to expand market share, lower costs and meet
customer expectations. To improve service quality, companies have invested in
technologies that enable them to concentrate customer service representatives,
or agents, into groups known as call centers. Many large corporations utilize
call centers as the primary method of interfacing with their customers. These
call centers are typically deployed in multiple locations and can be utilized to
provide a prioritized level of services for the most valued customers. Call
centers allow businesses to reduce costs and deliver premium customer service.
 
     The technology utilized by call centers has evolved dramatically over the
past three years. Historically, due to the closed nature of public networks,
corporations installed premises-based switching systems at the end of long
distance or local exchange telephone lines. Reliance on these switching systems
requires corporations to use proprietary closed solutions offered by service
providers where multi-vendor switching system interoperability was not possible.
Consequently, the call center solutions employed by most corporations have been
designed around the technological limits of premises-based switching systems and
the limitations of carrier networks, which prevent corporations from realizing
the potential benefits of virtual call centers. Virtual call centers draw upon
all of the organization's call response resources and utilize open systems-based
applications to enhance the capabilities of the existing call center
infrastructure by integrating it with existing business applications and data.
 
     The Company's Intelligent CallRouter (the "ICR") enables enterprise-wide
call routing and consolidated real-time management information at the network
level. The ICR is an advanced call-by-call routing server that supports multiple
routing clients independent of their location, toll-free carrier or switch
provider. The multi-carrier, multi-vendor capabilities of the ICR allow the user
to focus on delivering premium customer service without the limitations of
proprietary or customer developed solutions. Its open architecture enables
interoperability with other call processing and call volume management systems
within an enterprise and provides a means for integrating these various
stand-alone solutions. The ICR can be interfaced to agent scheduling, workflow
management and other call center management tools. The distributed software
fault tolerance implemented in the ICR provides the mission-critical reliability
required for enterprise-wide call distribution. The Company also offers

                                  RISK FACTORS
 
     An investment in the Common Stock offered hereby involves a high degree of
risk. In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the shares
of the Common Stock offered by this Prospectus. This Prospectus contains
forward-looking statements which 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 and in
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
   
     Limited Operating History; Future Operating Results Uncertain.  The Company
was incorporated in June 1993 and did not begin shipping products until May
1995. As of September 30, 1996, the Company had an accumulated deficit of
$6,901,000. The Company has experienced substantial revenue growth since product
introduction, and first achieved profitability in the first quarter of 1996.
However, due to the Company's limited operating history there can be no
assurance that such revenue growth and profitability will continue on a
quarterly or annual basis in the future. Future operating results will depend on
many factors, including the demand for the Company's products, the level of
product and price competition, the Company's success in expanding its direct
sales force and indirect distribution channels and the ability of the Company to
develop and market new products and control costs. In order to support the
growth of its business, the Company plans to significantly expand its level of
operations. Due to the anticipated increase in the Company's operating expenses
caused by this expansion, the Company's operating results will be adversely
affected if revenues do not increase. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations."
    
 
     Potential Fluctuations in Quarterly Operating Results.  The Company's
quarterly operating results may in the future vary significantly depending on
factors such as increased competition, the timing of new product announcements
and changes in pricing policies by the Company and its competitors, market
acceptance of new and enhanced versions of the Company's products, the size and
timing of significant orders, order cancellations by customers, the lengthy
sales cycles of the Company's products, changes in operating expenses, changes
in Company strategy, personnel changes and general economic factors. Product
revenues are also difficult to forecast because the market for the Company's
software products is rapidly evolving, and the Company's sales cycle varies
substantially from customer to customer. A significant portion of the Company's
revenues and operating income has been, and is expected to continue to be,
derived from software licensing fees from a limited number of customers.
Variability in the timing of such license fees may cause material fluctuations
in the Company's business, operating results and financial condition. The
Company's products and services generally require capital expenditures by
customers as well as the commitment of resources to implement the Company's
products. Accordingly, the Company is substantially dependent on its customers'
decisions as to the timing and level of such expenditures and resource
commitments. In addition, the Company typically realizes a significant portion
of license revenues in the last month of a quarter. As a result, the magnitude
of quarterly fluctuations may not become evident until late in, or after the
close of, a particular quarter. The Company's expenses are based in part on the
Company's expectations as to future revenue levels and to a large extent are
fixed in the short-term. If revenues do not meet expectations, the Company's
business, operating results and financial condition are likely to be materially
adversely affected. In particular, because only a small portion of the Company's
expenses varies with revenues, net income may be disproportionately affected by
a reduction in revenues. As a result, the Company believes that period-to-period
comparisons of its operating results are not necessarily meaningful and should
not be relied upon as indications of future performance. Due to the foregoing
factors, it is likely that in some future quarter the Company's revenue or
operating results will be below the expectations of public market analysts and
investors. In such event, the price of the Company's Common Stock could be
materially
 
                                        6
<PAGE>   11
 
adversely affected. See "Selected Financial Data" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
     Risks Associated with Customer Concentration and One-Time License Fees.  A
significant portion of the Company's revenues to date has been derived from a
limited number of customers. Revenues attributable to the Company's five largest
customers accounted for approximately 94.4% and 62.2% of the Company's total
revenues in 1995 and the nine months ended September 30, 1996, respectively.
Fidelity Investments ("Fidelity"), Sprint Corporation and America Online
accounted for approximately 38.3%, 25.9% and 20.0%, respectively, of the
Company's total revenues in 1995, and Fidelity, Optus Systems PTY Ltd ("Optus"),
GTE Communication Systems Corporation, MCI Telecommunications Corporation
("MCI"), and USAir Corp. accounted for approximately 19.7%, 15.9%, 10.2%, 8.7%
and 7.7%, respectively, of the Company's total revenues for the nine months
ended September 30, 1996. The Company expects that it will continue to be
dependent upon a limited number of customers for a significant portion of its
revenues in future periods. None of the Company's customers, other than MCI and
Optus, is contractually obligated to license or purchase additional products or
services from the Company and these customers generally have acquired fully-paid
licenses to the installed product. As a result of this customer concentration,
the Company's business, operating results and financial condition could be
materially adversely affected by the failure of anticipated orders to
materialize or by deferrals or cancellations of orders. In addition, a
significant portion of the Company's revenues to date has been derived from
initial license fees from customers who have acquired fully-paid licenses to the
installed product. There can be no assurance that any of the Company's customers
will continue to purchase the Company's products and services in amounts similar
to previous periods or that revenues from customers that have accounted for
significant revenues in past periods, individually or as a group, will continue
or, if continued, will reach or exceed historical levels in any future period.
The Company's operating results may in the future be subject to substantial
period-to-period fluctuations as a consequence of such customer concentration.
See "Business -- Customers."
 
     Lengthy Sales and Implementation Cycles.  The Company's products are
typically intended for use in applications that may be critical to a customer's
business. The license and implementation of the Company's software products
generally involves a significant commitment of resources by prospective
customers. As a result, the Company's sales process is often subject to delays
associated with lengthy approval processes that typically accompany significant
capital expenditures. For these and other reasons, the sales cycle associated
with the license of the Company's products is often lengthy (recently averaging
approximately six months) and subject to a number of significant delays over
which the Company has little or no control. In addition, the Company does not
recognize license revenues until all significant post-delivery obligations have
been satisfied, including the development of specific product features which, in
certain cases, can take several quarters. The time required to implement the
Company's products can vary significantly with the needs of its customers and is
generally a process that extends for several months. There can be no assurance
that the Company will not experience delays in the future, particularly if the
Company receives orders for large, complex installations. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Business -- Sales and Marketing" and "-- Customer Service and Support."
 
     Product Concentration; Dependence on Growth in Call Center Market.  The
Company currently derives substantially all of its revenues from licenses of the
Intelligent CallRouter and related services. Broad market acceptance of the
Company's product is critical to the Company's future success. As a result, a
decline in demand for or failure to achieve broad market acceptance of the
Intelligent CallRouter as a result of competition, technological change or
otherwise, would have a material adverse effect on the business, operating
results and financial condition of the Company. A decline in sales of the
Intelligent CallRouter could also have a material adverse effect on sales of
other Company products that may be sold to Intelligent CallRouter customers. The
Company's future financial performance will depend in part on the successful
development, introduction and customer acceptance of new and enhanced versions
of the Intelligent CallRouter and other
 
                                        7
<PAGE>   12
 
products. There can be no assurance that the Company will continue to be
successful in marketing the Intelligent CallRouter or any new or enhanced
products. See "Business -- Products," "-- Product Development" and
"-- Competition."
 
     The Intelligent CallRouter is utilized in call centers maintained by
companies in a variety of industries. This product is currently expected to
account for substantially all of the Company's future revenues. Although demand
for the Intelligent CallRouter has grown in recent quarters, the call center
market is still an emerging market. The Company's future financial performance
will depend in large part on continued growth in the number of organizations
adopting software applications to enhance their responsiveness to customers and
the number of applications developed for use in those environments. There can be
no assurance that the market for the Company's products will continue to grow.
In addition, changes in the business or pricing strategies of the interexchange
carriers or ACD vendors could adversely affect demand for the Company's
products. If the call center market fails to grow or grows more slowly than the
Company currently anticipates, the Company's business, operating results and
financial condition would be materially adversely affected. During recent years,
segments of the telecommunications industry have experienced significant
economic downturns characterized by decreased product demand, price erosion,
work slowdowns and layoffs. The Company's operations may in the future
experience substantial fluctuations from period to period as a consequence of
such industry patterns, general economic conditions affecting the timing of
orders from major customers, and other factors affecting capital spending. There
can be no assurance that such factors will not have a material adverse effect on
the Company's business, operating results and financial condition. See
"Business -- Industry Background."
 
     Competition.  The market for telecommunications software products is
intensely competitive and is subject to rapid technological change. Although to
date the Company has experienced limited competition, the Company expects
competition to increase significantly in the future. Currently, the Company's
principal competitors are the interexchange carriers, particularly AT&T, and to
a lesser extent MCI and Sprint, which provide proprietary call routing solutions
as part of their service offerings. In addition, a number of other companies
have introduced or announced their intention to introduce products that could be
competitive with the Company's products, including Genesys Telecommunications
Laboratories and IEX Corporation. Additional competitors, including traditional
ACD providers, such as Lucent Technologies, Aspect Telecommunications
Corporation, Northern Telecommunications, Inc. and Rockwell International
Corporation, may enter the market by enhancing their proprietary private network
solutions or by entering into arrangements with the interexchange carriers. The
Company believes that, to date, approximately one-half of the Company's
customers have purchased the Company's products to replace or enhance existing
call routing solutions offered by the interexchange carriers. The Company's
other customers have purchased the Company's products in order to implement a
virtual call center solution for the first time. Increased competition is likely
to result in price reductions, reduced gross margins and loss of market share,
any of which could materially adversely affect the Company's business, operating
results and financial condition. Some of the Company's current, and many of the
Company's potential, competitors have significantly greater financial,
technical, marketing and other resources than the Company. As a result, they may
be able to respond more quickly to new or emerging technologies and changes in
customer requirements, or to devote greater resources to the development,
promotion and sale of their products than the Company. In addition, one or more
interexchange carriers, including MCI, Optus and Sprint which are customers of
the Company, could choose to provide or distribute competitive products and
services. Accordingly, there can be no assurance that the Company will be able
to compete successfully against current and future competitors or that
competitive pressures faced by the Company will not materially adversely affect
its business, operating results and financial condition. Moreover, the Company
may be subject to potential conflicts of interest from time to time if a
customer, such as MCI, Optus or Sprint, provides or distributes competitive
products or services. In this regard, a customer which elects to provide or
distribute competitive products or services could make strategic decisions with
respect to pricing and other matters relating to products provided or
distributed by it which could adversely affect the Company's business, operating
results and financial condition. See "Business -- Competition."

<PAGE>   13
 
     Dependence on New Products and Rapid Technological Change.  The market for
the Company's products is characterized by rapid technological change, frequent
new product introductions and evolving industry standards. The introduction of
products embodying new technologies and the emergence of new industry standards
can render existing products obsolete and unmarketable. The life cycles of the
Company's products are difficult to estimate. The Company's future success will
depend upon its ability to enhance its current products and to develop and
introduce new products on a timely basis that keep pace with technological
developments and emerging industry standards and address the increasingly
sophisticated needs of its customers. There can be no assurance that the Company
will be successful in developing and marketing product enhancements or new
products that respond to technological change or evolving industry standards,
that the Company will not experience difficulties that could delay or prevent
the successful development, introduction and marketing of these products, or
that its new products and product enhancements will adequately meet the
requirements of the marketplace and achieve market acceptance. If the Company is
unable, for technological or other reasons, to develop and introduce new
products or enhancements of existing products in a timely manner in response to
changing market conditions or customer requirements, the Company's business,
operating results and financial condition will be materially adversely affected.
In June 1996, the Company released a new version of its Intelligent CallRouter
and the Company plans to introduce additional enhancements in the near term.
These enhancements are subject to significant technical risks. If these
enhancements are delayed or if they do not achieve market acceptance, the
Company's business, operating results and financial condition will be materially
adversely affected. See "Business -- Product Development."
 
     Risk of Product Defects or Development Delays.  Software products as
complex as those offered by the Company frequently contain errors or failures,
especially when first introduced or when new versions are released. Although the
Company conducts extensive product testing, new products and enhancements could
contain software errors and, as a result, the Company could experience delays in
recognizing revenues during the period required to correct these errors. The
Company could in the future lose revenues as a result of software errors or
defects. The Company's products are typically intended for use in applications
that may be critical to a customer's business. As a result, the Company believes
that its current customers and potential customers have a greater sensitivity to
product defects than the market for software products generally. Although the
Company has not experienced material adverse effects resulting from any such
errors to date, there can be no assurance that, despite testing by the Company
and by current and potential customers, errors will not be found in new products
or releases after commencement of commercial shipments, resulting in the loss of
revenue or delay in market acceptance, diversion of development resources,
damage to the Company's reputation, or increased service and warranty costs, any
of which could have a material adverse effect upon the Company's business,
operating results and financial condition.
 
     Management of Growth; Dependence Upon Key Personnel.  The Company has
recently experienced a period of rapid growth in revenues that has placed a
significant strain upon its management systems and resources. The Company's
ability to compete effectively and to manage future growth, if any, will require
the Company to continue to improve its financial and management controls,
reporting systems and procedures on a timely basis and expand, train and manage
its employee work force. There can be no assurance that the Company will be able
to do so successfully. The Company's failure to do so could have a material
adverse effect upon the Company's business, operating results and financial
condition. The Company's future performance depends in significant part upon the
continued service of its key technical, sales and senior management personnel,
none of whom is bound by an employment agreement. The loss of the services of
one or more of the Company's executive officers could have a material adverse
effect on the Company's business, operating results and financial condition. The
Company's future success also depends on its continuing ability to attract and
retain highly qualified technical, sales and managerial personnel.
 
                                        9
<PAGE>   14
 
Competition for such personnel is intense, and there can be no assurance that
the Company can retain its key technical, sales and managerial employees or that
it can attract, assimilate or retain other highly qualified technical, sales and
managerial personnel in the future. See "Business -- Sales and Marketing" and
"Management."
 
     Risks Associated with International Expansion.  International sales
accounted for approximately 21.6% of the Company's revenues for the nine months
ended September 30, 1996. As part of its business strategy, the Company is
seeking opportunities to expand its products into international markets. The
Company believes that such expansion is important to the Company's ability to
continue to grow and to market its products and services. In marketing its
products and services internationally, however, the Company will face new
competitors, some of whom may have established strong relationships with
carriers. In addition, the ability of the Company to enter the international
markets will be dependent upon the Company's ability to integrate its products
with local proprietary networks in foreign countries. There can be no assurance
that the Company will be successful in integrating its products with these
proprietary networks or marketing or distributing its products abroad or that,
if the Company is successful, its international revenues will be adequate to
offset the expense of establishing and maintaining international operations. To
date, the Company has limited experience in marketing and distributing its
products internationally. In addition to the uncertainty as to the Company's
ability to establish an international presence, there are certain difficulties
and risks inherent in doing business on an international level, such as
compliance with regulatory requirements and changes in these requirements,
export restrictions, export controls relating to technology, tariffs and other
trade barriers, protection of intellectual property rights, difficulties in
staffing and managing international operations, longer payment cycles, problems
in collecting accounts receivable, political instability, fluctuations in
currency exchange rates and potentially adverse tax consequences. There can be
no assurance that one or more of such factors will not have a material adverse
effect on any international operations established by the Company and,
consequently, on the Company's business, operating results and financial
condition.
 
     Dependence on Proprietary Technology; Risks of Infringement.  The Company
is dependent upon its ability to protect its proprietary technology. To protect
its proprietary rights, the Company relies on a combination of patents,
copyrights, trademarks, trade secret laws and confidentiality procedures. The
Company has been issued one United States patent and also has one patent
application pending in the United States and internationally. There can be no
assurance that patents will be issued with respect to the pending or future
patent applications or that the Company's existing or future patents will be
upheld as valid or will prevent the development of competitive products. In
addition, existing patent, copyright, trademark and trade secret laws afford
only limited protection, and many countries' laws do not protect the Company's
proprietary rights to the same extent as do the laws of the United States.
Accordingly, there can be no assurance that the Company will be able to protect
its proprietary rights against unauthorized third-party copying, use or
exploitation, any of which could have a material adverse effect on the Company's
business, operating results and financial condition. Attempts may be made to
copy or reverse engineer aspects of the Company's products, or to obtain, use or
exploit information or methods which the Company deems proprietary.
Additionally, there can be no assurance that the Company's customers and others
will not develop products which infringe upon the Company's rights, or that
compete with the Company's products. Policing the use of the Company's products
is difficult and expensive, and there is no assurance that such efforts would
prove effective. Litigation or other action may be necessary in the future to
enforce the Company's proprietary rights, to seek and confirm patent protection
for the Company's technologies, or to determine the validity and scope of the
proprietary rights of others. Any litigation could be time-consuming and result
in significant costs. The Company expects that its software products may
increasingly be subject to claims as the number of products and competitors in
the Company's markets grows and the functionality of such products overlaps. Any
such claims, with or without merit, could result in substantial costs and
diversions of resources and management's attention, and could cause product
shipment delays or require the Company to enter into royalty or licensing
agreements, any of which could have a material adverse
 
                                       10
<PAGE>   15
 
impact on the Company's business, operating results and financial condition.
Such royalty or licensing agreements, if required, may not be available on terms
acceptable to the Company, if at all, which could have a material adverse effect
upon the Company's business, operating results and financial condition. See
"Business -- Intellectual Property and Other Proprietary Rights."
 
     Dependence on a Single Supplier for a Certain Product.  The software and
network adapter necessary to enable the Company's Intelligent CallRouter to
interface with the AT&T network is licensed by the Company from a single vendor
under a perpetual, fully-paid license. Although the Company has access to the
source code underlying this software and rights to manufacture the network
adapter, if for any reason the vendor does not make the software or network
adapter available to the Company, there can be no assurance that the Company
will be able to develop these products on a timely basis. See
"Business -- Intellectual Property and Other Proprietary Rights."
 
     Product Liability.  The Company's license agreements with its customers
generally contain provisions designed to limit the Company's exposure to
potential product liability claims. However, it is possible that the limitation
of liability provisions contained in the Company's license agreements may not be
effective under the laws of certain jurisdictions. Although the Company has not
experienced any product liability claims to date, the sale and support of
products by the Company may entail the risk of such claims, and there can be no
assurance that the Company will not be subject to such claims in the future. A
successful product liability claim brought against the Company could have a
material adverse effect upon the Company's business, operating results and
financial condition.
 
     No Prior Public Market; Determination of Public Offering Price; Potential
Volatility of Stock Price.  Prior to this offering there has been no public
market for the Common Stock, and there can be no assurance that an active
trading market will develop or be sustained. The initial public offering price
for the Common Stock will be determined by negotiation between the Company and
the Representatives of the Underwriters. Among the factors to be considered in
determining the initial public offering price are prevailing market and economic
conditions, revenues and earnings of the Company, the market valuations of other
companies engaged in activities similar to those of the Company, estimates of
the business potential and prospects of the Company, the present state of the
Company's business operations, the Company's management and other factors deemed
relevant, and may not be indicative of the market price of the Common Stock
after this offering. In addition, the stock markets in general, and the market
prices for high technology companies in particular, have historically
experienced volatility that at times has been unrelated to the operating
performance of such companies. The trading price of the Common Stock could also
be subject to significant fluctuations in response to variations in quarterly
results of operations, announcements of new products or acquisitions by the
Company or its competitors, governmental regulatory action, other developments
or disputes with respect to proprietary rights, general trends in the industry
and overall market conditions, and other factors. These broad market and
industry fluctuations may adversely affect the market price of the Common Stock
regardless of the Company's operating performance. See "Underwriting" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
   
     Shares Eligible for Future Sale; Registration Rights.  A substantial number
of outstanding shares of Common Stock and shares of Common Stock issuable upon
exercise of outstanding options will become available for future sale in the
public market at prescribed times or pursuant to the exercise of registration
rights. Sales of substantial amounts of such shares in the public market could
adversely affect the market price of the Common Stock. Approximately 2,086
shares may be eligible for resale in the public market without restriction in
reliance on Rule 144(k) under the Securities Act of 1933, as amended (the
"Securities Act"). An additional 344,346 shares may be eligible for resale in
the public market without restriction in reliance on Rule 144(k) upon the
expiration of certain 180-day lock-up agreements. In addition, beginning 90 days
after the date of this Prospectus, 6,833,128 shares of Common Stock, all of
which shares are subject to 180-day lockup agreements with the Representatives
of the Underwriters, will be eligible for resale in the public market subject to
the restrictions of Rule 144 under the Securities Act. See "Shares
    
 
                                       11
<PAGE>   16
 
Eligible for Future Sale." In addition, the Securities and Exchange Commission
has proposed an amendment to Rule 144 which would reduce the holding period
before shares subject to Rule 144 become eligible for sale in the public market.
This proposal, if adopted, would substantially increase the number of shares of
the Company's Common Stock eligible for immediate sale following the expiration
of the lock-up period. Approximately 90 days after the date of this Prospectus,
the Company intends to register on one or more registration statements on Form
S-8 approximately 2,972,341 shares of Common Stock issuable under its restricted
stock purchase plan, stock restriction agreements and stock option plan. Shares
covered by such registration statements will be eligible for sale in the public
market after the effective date of such registration, except for 1,704,146
shares which are subject to 180-day lockup agreements with Representatives of
the Underwriters.
 
   
     The executive officers and the directors of the Company and certain
stockholders, who in the aggregate own beneficially approximately 10,753,518
shares of Common Stock (including shares issuable pursuant to the exercise of
stock options), have agreed pursuant to lock-up agreements that they will not,
without the prior written consent of Alex. Brown & Sons Incorporated, sell or
otherwise dispose of any such shares of Common Stock beneficially owned by them
for a period of 180 days from the date of this Prospectus. Upon the expiration
of these lock-up agreements, 8,090,308 of such shares (including shares issuable
pursuant to the exercise of stock options) will become eligible for sale in the
public market, subject to the provisions of Rule 144 under the Securities Act.
    
 
   
     As of the date of this Prospectus, the holders of 9,529,862 shares of
Common Stock are entitled to certain registration rights with respect to such
shares. If the Company is required to register shares held by any such holder
pursuant to the exercise of its or his registration rights, such sales may have
an adverse effect on the Company's ability to raise needed capital or adversely
affect the Common Stock. See "Management," "Principal and Selling Stockholders,"
"Shares Eligible for Future Sale" and "Underwriting."
    
 
   
     Control by Existing Stockholders.  Following this offering, the Company's
executive officers, directors and their respective affiliates, in the aggregate,
will beneficially own approximately 44.5% of the Company's outstanding Common
Stock (43.3% of the outstanding Common Stock if the over-allotment option is
exercised in full). As a result, these stockholders, if acting together, would
be able to exert substantial influence over the Company and to effectively
control most matters requiring approval by the stockholders of the Company,
including the election of directors. The voting power of these stockholders
under certain circumstances could have the effect of delaying or preventing a
change in control of the Company. See "Management," "Principal and Selling
Stockholders" and "Description of Capital Stock."
    
 
     Certain Anti-Takeover Provisions Affecting Stockholders.  The Company's
Restated Certificate of Incorporation and Bylaws contain provisions that might
diminish the likelihood that a potential acquiror would make an offer for the
Common Stock, or impede a transaction favorable to the interest of the
stockholders, or increase the difficulty of removing an incumbent Board of
Directors or management. After the closing of this offering, the Company's Board
of Directors will have the authority, without further stockholder approval, to
issue up to 5,000,000 shares of Preferred Stock in one or more series and to
determine the price, rights, preferences and privileges of those shares. The
rights of the holders of Common Stock will be subject to, and may be adversely
affected by, the rights of the holders of any Preferred Stock that may be issued
in the future. The issuance of shares of Preferred Stock, while potentially
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of making it more difficult for
a third party to acquire a majority of the outstanding voting stock of the
Company. The Company has no present plans to issue shares of Preferred Stock. In
addition, the Company is subject to the anti-takeover provisions of Section 203
of the Delaware General Corporation Law, which will prohibit the Company from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved in
a prescribed manner. The application of Section 203 also could
 
                                       12
<PAGE>   17
 
have the effect of delaying or preventing a change of control of the Company.
Furthermore, certain provisions of the Company's Restated Certificate of
Incorporation, including provisions that provide for the Board of Directors to
be divided into three classes to serve for staggered three-year terms, may have
the effect of delaying or preventing a change of control of the Company, which
could adversely affect the market price of the Company's Common Stock. Each of
the Company's executive officers is a party to a change in control agreement
which provides for salary continuation and other benefits upon the occurrence of
certain events following a change of control. These agreements could have the
effect of discouraging a change of control of the Company. See "Description of
Capital Stock -- Certain Charter, Bylaw and Statutory Provisions Affecting
Stockholders" and "Management -- Employment Agreements and Change of Control
Arrangements."
 
   
     Dilution.  Purchasers in this offering will suffer an immediate and
substantial dilution, in the amount of $9.31 per share, in the net tangible book
value of the Common Stock from the initial public offering price. See
"Dilution."
    
 
     No Dividends.  The Company has never declared or paid cash dividends to its
stockholders and does not anticipate paying cash dividends in the foreseeable
future. See "Dividend Policy."
 
     Discretion as to Use of Proceeds.  The principal purposes of this offering
are to increase the Company's equity capital, to create a public market for the
Company's Common Stock, to increase the visability of the Company in the
marketplace and to facilitate future access to public equity markets. As of the
date of this Prospectus, the Company has no specific plans to use the net
proceeds from this offering other than for working capital and general corporate
purposes, including repayment of bank indebtedness. Accordingly, the Company's
management will retain broad discretion as to the allocation of the net proceeds
from this offering. Pending any such uses, the Company plans to invest the net
proceeds in the investment grade, interest-bearing securities. See "Use of
Proceeds."

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the 2,200,000 shares of
Common Stock offered by the Company pursuant to this offering are estimated to
be $22,929,000 ($25,763,000 if the Underwriters' over-allotment option is
exercised in full), assuming an initial public offering price of $11.50 per
share and after deducting the estimated underwriting discounts and commissions
and offering expenses payable by the Company. The principal purposes of this
offering are to increase the Company's equity capital, to create a public market
for the Common Stock, to increase the visibility of the Company in the
marketplace and to facilitate future access by the Company to public equity
markets.
    
 
   
     The Company anticipates using a portion of the net proceeds to repay in
full the Company's existing bank indebtedness and the balance for general
corporate purposes, including working capital. At September 30, 1996, the
Company's bank indebtedness consisted of equipment lines of credit which
amounted to approximately $823,000, payable in monthly installments. Future
principal payments are $101,000, $347,000, $252,000, $99,000 and $24,000 for the
remainder of 1996 and annually for 1997, 1998, 1999 and 2000, respectively. At
September 30, 1996, interest accrued on such loans at the bank's prime rate
(8.25% at September 30, 1996) per annum. The proceeds of such loans were used by
the Company to acquire capital equipment. The Company may seek acquisitions of
businesses, products and technologies that are complementary to those of the
Company, and a portion of the net proceeds may be used for such acquisitions in
as early as the fourth quarter of 1996. While the Company engages from time to
time in discussions with respect to potential acquisitions, the Company has no
plans, commitments or agreements with respect to any such acquisitions as of the
date of this Prospectus, and there can be no assurance that any such
acquisitions will be made. 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 any cash dividends on its Common
Stock and currently intends to retain all available funds for use in the
operation and expansion of its business. The Company does not, therefore,
anticipate that any cash dividends will be declared or paid in the foreseeable
future. The Company's current loan agreement prohibits the payment of cash
dividends without the bank's consent. See Financial Statements and the related
Notes.

    Preferred Stock into 8,315,672 shares of Common Stock upon the closing of
    this offering, based upon an assumed initial public offering price of $11.50
    per share.
    
 
   
(2) Adjusted to give effect to the sale of 2,200,000 shares of Common Stock
    offered by the Company hereby at an assumed initial public offering price of
    $11.50 per share, after deducting the estimated underwriting discounts and
    commissions and offering expenses payable by the Company, and the
    anticipated application of the net proceeds therefrom.
    
 
(3) On September 26, 1996, the Company's Board of Directors and stockholders
    approved amendments to the Company's Certificate of Incorporation to
    increase the number of authorized shares of Common Stock from 14,000,000 to
    40,000,000 and to set the number of authorized shares of undesignated
    Preferred Stock at 5,000,000 to be effected upon the closing of this

<TABLE>
     The pro forma net tangible book value of the Company at September 30, 1996,
after giving effect to the automatic conversion of Convertible Preferred Stock
upon the closing of the offering, was approximately $5,225,000, or $0.49 per
share of Common Stock. Net tangible book value per share is equal to the
Company's total tangible assets less total liabilities, divided by the total
number of shares of Common Stock outstanding. Net tangible book value dilution
per share represents the difference between the amount per share paid by
purchasers of shares of Common Stock in the offering made hereby and the net
tangible book value per share of Common Stock immediately after completion of
this offering. After giving effect to the sale by the Company of the 2,200,000
shares of Common Stock offered hereby at an assumed initial public offering
price of $11.50 per share, and after deducting the estimated underwriting
discounts and commissions and offering expenses, the pro forma net tangible book
value of the Company as of September 30, 1996 would have been $28,154,000 or
$2.19 per share of Common Stock. This represents an immediate increase in such
pro forma net tangible book value of $1.70 per share to existing stockholders
and an immediate dilution of $9.31 per share to new investors purchasing shares
in this offering. If the initial public offering price is higher or lower, the
dilution to the new investors will be, respectively, greater or less. The
following table illustrates this per share dilution:

     The foregoing tables assume no exercise of the Underwriters' over-allotment
option or of options to purchase an aggregate of 860,396 shares of Common Stock
that were outstanding at September 30, 1996. To the extent that the
Underwriters' over-allotment option and other options are exercised in the
future, there will be further dilution to new investors. If all of the
outstanding options were exercised in full, the dilution per share to new
investors would be $9.32. Such exercises would increase the number of shares
held by existing stockholders to 11,500,905 shares, or 83.9%, of the total
number of shares of Common Stock to be outstanding after this offering, and
would (i) decrease the percentage ownership of the Company held by the new
investors to 16.1% of the total number of shares of Common Stock to be
outstanding after this offering, (ii) increase the total consideration paid to
the Company by existing stockholders to $13,941,000, or 35.5% of the total
consideration paid to the Company, and (iii) increase the average price per
share paid by existing stockholders to $1.21. See "Management -- Stock Plans."

          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 may differ significantly from the
results discussed in the forward-looking statements. Factors that could cause or
contribute to such a difference include, but are not limited to, those discussed
in "Risk Factors." The following discussion of the financial condition and
results of operations of the Company should be read in conjunction with the
Company's Financial Statements and Notes thereto, and the other financial
information included elsewhere in this Prospectus.
 
OVERVIEW
 
     The Company was incorporated in June 1993 to develop telecommunications
software solutions that enable enhanced call center applications. From inception
through the first half of 1995, the Company was engaged principally in research
and product development of its Intelligent CallRouter product. The Company's
first customer installation of the Intelligent CallRouter occurred in May 1995
and the Company recognized its first revenue from customer shipments in the
fourth quarter of 1995. The Company initially achieved profitability in the
first quarter of 1996. Unit shipments have grown due to increasing market
acceptance of the Company's product and increases in the size of the Company's
direct sales force. The Company expects that the Intelligent CallRouter product
will account for substantially all of its revenue for the foreseeable future.
The Company believes that its future performance will depend in large part on
its ability to maintain and enhance its current Intelligent CallRouter product
line, develop new products that achieve market acceptance, maintain
technological competitiveness, meet an expanding range of customer requirements
and continue to recruit highly skilled and qualified software professionals. The
Company primarily markets its products in the United States through a direct
sales force which is complemented by strategic sales channels, including MCI,
selected resellers and an international partner.
 
     The Company's revenue is derived from two sources: software licenses and
services. Software license revenue, which has historically represented the
majority of the Company's total revenue, is generally payable within thirty days
of product acceptance. The Company recognizes software license fee revenues upon
shipment unless there are significant post-delivery obligations. When
significant post-delivery obligations exist, revenues are deferred until such
obligations have been satisfied. Service revenues consist primarily of
maintenance, installation and training revenues. Maintenance revenues are
recognized ratably over the term of the support period, which is typically
twelve months. Installation and training revenues are recognized when the
services are performed.
 
     A significant portion of the Company's revenues to date has been derived
from a limited number of customers. Revenues attributable to the Company's five
largest customers accounted for approximately 94.4% and 62.2% of the Company's
total revenues in 1995 and the nine months ended September 30, 1996,
respectively. The Company expects that it will continue to be dependent upon a
limited number of customers for a significant portion of its revenues in future
periods. See "Risk Factors -- Risks Associated with Customer Concentration."
 
     The Company has experienced substantial revenue growth since product
introduction and first achieved profitability in the first quarter of 1996.
However, due to the Company's limited operating history there can be no
assurance that such revenue growth and profitability will continue on a
quarterly or annual basis in the future. Future operating results will depend on
many factors, including the demand for the Company's products, the level of
product and price competition, the Company's success in expanding its direct
sales force and indirect distribution channels and the ability of the Company to
develop and market new products and control costs. In order to support the
growth of its business, the Company plans to significantly expand its level of
operations. Due to the anticipated increase in the Company's operating expenses
caused by this expansion, the Company's operating results will be adversely
affected if revenues do not increase. Although demand for the Intelligent
CallRouter has grown in recent quarters, the call center market is still an
emerging market. The Company's future financial performance will depend in large
part on
 
                                       19
<PAGE>   24
 
continued growth in the number of organizations adopting software applications
to enhance their responsiveness to customers and the number of applications
developed for use in these environments. See "Risk Factors -- Limited Operating
History; Future Operating Results Uncertain."
 
     The Company's quarterly operating results may in the future vary
significantly depending on factors such as increased competition, the timing of
new product announcements and changes in pricing policies by the Company and its
competitors, market acceptance of new and enhanced versions of the Company's
products, the size and timing of significant orders, order cancellations by
customers, changes in operating expenses, changes in Company strategy, personnel
changes, and general economic factors. The Company's expense levels are based,
in part, on its expectations of future revenues and to a large extent are fixed
in the short-term. If revenue levels are below expectations, the Company's
business, operating results and financial condition are likely to be materially
adversely affected. Net income may be disproportionately affected by a reduction
in revenues because a proportionately smaller amount of the Company's expenses
varies with its revenues. As a result, the Company believes that
period-to-period comparisons of its results of operations are not necessarily
meaningful and should not be relied upon as indications of future performance.
See "Risk Factors -- Potential Fluctuations in Quarterly Operating Results."
 
OPERATING RESULTS
 
<TABLE>
     The following table presents selected unaudited financial information for
the Company's last four quarters (since the Company began recognizing revenue),
as well as the percentage of the Company's total revenues represented by each
item. The Company has not included quarterly financial information for any
quarter prior to the quarter ended December 31, 1995 as the Company was a
development stage enterprise and expenses in those quarters related primarily to
the research and development of the Company's products and initial marketing
efforts. In the opinion of the Company's management, this unaudited information
reflects all adjustments, consisting only of normal recurring adjustments,
necessary to present fairly this information when read in conjunction with the
Financial Statements and Notes thereto appearing elsewhere in this Prospectus.
The Company's operating results for any one quarter are not necessarily
indicative of results for any future period.

REVENUES
 
     Revenues consist of software license fees and services. The Company
recorded no revenues until the fourth quarter of 1995. Since the fourth quarter
of 1995, the Company's quarterly revenues have increased sequentially by 19.9%,
11.4% and 16.9% for the first, second and third quarter of 1996, respectively.
The increases were due to increases in unit sales. The Company did not record
any revenues from international sales until the first quarter of 1996.
International sales represented 21.6% of revenues for the nine months ended
September 30, 1996. To date, the Company's international sales have been
denominated in U.S. currency. Most of the Company's revenues have been from
software license and installation revenues. The Company anticipates that
maintenance revenues will increase as a percentage of revenues as the Company's
customer base increases. Service and other revenues for the fourth quarter of
1995 were derived solely from installation services. Installation and
maintenance services represented 68% and 28%, respectively, of total service and
other revenues for the nine months ended September 30, 1996. Installation
services are one time sales. Maintenance contracts are generally twelve months
in duration and are subject to customer renewal.
 
COST OF REVENUES
 
     To date, cost of software licenses consists principally of product warranty
costs and costs attributable to a discontinued marketing program offered to the
Company's first five customers. Cost of software licenses as a percentage of
software license revenue were 19.4%, 4.4%, 5.9% and 2.5% for the fourth quarter
of 1995 and the first, second and third quarter of 1996, respectively. The
decreases in percentage for the fourth quarter of 1995, the first quarter of
1996 and the third quarter of 1996 resulted from decreasing hardware costs. As
part of the initial introduction of the Company's software products, the Company
purchased and resold certain hardware required by customers in order to
implement the Company's products. This program was discontinued as the Company's
general practice in September 1995. The Company does not anticipate that
hardware costs will represent a significant portion of cost of revenues in the
future. The increase in dollars and as a percentage of software license revenue
in the second quarter of 1996 as compared to the first and third quarter of
1996, was the result of an increase in the provision for warranty expense.
 
   
     Cost of services consists principally of the costs incurred to provide
installation, consulting, maintenance and training services. The expenses
incurred to provide these services are comprised primarily of personnel costs,
travel and facility costs. Cost of services as a percentage of services and
other revenues were 137.9%, 207.5%, 159.4% and 116.3% for the fourth quarter of
1995 and the first, second and third quarter of 1996, respectively. The dollar
increases were a result of start-up costs associated with the building of a
customer support infrastructure to handle the anticipated future growth in
customers. The Company anticipates that the cost of services will increase in
absolute dollars, while decreasing as a percentage of services and other
revenues in the foreseeable future. The Company anticipates that services
revenues will begin to exceed the related costs of services and other expenses
as the Company begins to benefit from cost efficiencies anticipated as the
customer base and maintenance customer renewals increase.
    
 
OPERATING EXPENSES
 
   
     Research and Development.  Research and development expenses consist
principally of personnel and facility costs. Research and development expenses
as a percentage of total revenues were 39.2%, 35.7%, 35.8% and 34.2% for the
fourth quarter of 1995 and the first, second and third quarter of 1996,
respectively. The decrease in percentage from the fourth quarter to the first
quarter was the result of expenses remaining relatively constant during the
period while the Company experienced significant revenue growth. The increase in
absolute dollars from the fourth quarter of 1995 through the third quarter of
1996 was the result of an increase in employees and the associated hiring costs
each quarter. The Company anticipates that research and development expenses
will continue to increase in absolute dollars, while decreasing as a percentage
of total revenues in the foreseeable
    
 
                                       21
<PAGE>   26
 
future. To date, the Company's development efforts have not resulted in any
capitalized software development costs.
 
   
     Sales and Marketing.  Sales and marketing expenses consist principally of
personnel costs, travel, promotional expenses and facility costs. Sales and
marketing expenses as a percentage of total revenues were 31.2%, 33.8%, 28.1%
and 32.3% for the fourth quarter of 1995 and the first, second and third quarter
of 1996, respectively. The Company recorded a charge associated with the
termination of an employee in the first quarter of 1996. Excluding this charge,
the Company would have experienced an increase in sales and marketing expenses
in absolute dollars but a decrease as a percentage of total revenues from the
preceding quarter. The increase in sales and marketing expenses was the result
of adding sales personnel to the direct sales force and an increase in
commission expense attributable to higher sales. The Company anticipates that
sales and marketing expenses will increase in absolute dollars and as a
percentage of total revenues in the foreseeable future.
    
 
   
     General and Administrative.  General and administrative expenses consist
principally of personnel costs for administrative, finance, information systems,
human resources and general management personnel, as well as legal expenses and
facility costs. General and administrative expenses as a percentage of total
revenues were 25.2%, 11.1%, 11.8% and 10.8% for the fourth quarter of 1995 and
the first, second and third quarter of 1996, respectively. General and
administrative expenses in the fourth quarter of 1995 were higher than in any of
the first three quarters in 1996 principally due to the settlement of litigation
for approximately $127,000. General and administrative expenses have been
increasing in absolute dollars since the first quarter of 1996 due to an
increase in employees and travel. The Company anticipates that general and
administrative expenses will increase in absolute dollars, while decreasing as a
percentage of total revenues for the foreseeable future.
    
 
INTEREST INCOME, NET
 
     Interest income, net, of $52,000, $40,000, $45,000 and $46,000 for the
fourth quarter of 1995 and the first, second and third quarter of 1996,
respectively, resulted from investments of the Company's cash balances, net of
interest expense incurred on bank term notes.
 
PROVISION FOR INCOME TAXES
 
     The Company reported a net loss in each completed year and accordingly did
not provide for an income tax liability. See Financial Statements and Notes
thereto. As of September 30, 1996, the Company had net operating loss
carryforwards of approximately $1,400,000 for federal and state income tax
purposes, and capitalized start-up costs of approximately $4,800,000 that may be
used to offset future federal income tax, if any. The Company also has $117,000
of federal research and development tax credits which expire beginning in the
year 2009 if not utilized. An ownership change, as defined in the Tax Reform Act
of 1986, may restrict the utilization of certain tax attributes. A valuation
allowance has been recorded for the entire deferred tax asset as a result of
uncertainties regarding the realization of the asset due to the limited history
of operating profits. See the Financial Statements and Notes thereto.
 
INFLATION
 
     Certain of the Company's expenses increase with general inflation in the
economy. However, the Company does not believe that its results of operations
have been, or will be, adversely affected by inflation.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At September 30, 1996, the Company had cash and cash equivalents of
$5,812,000, an increase of approximately $1,275,000 from December 31, 1995. The
Company has financed its operations to
 
                                       22
<PAGE>   27
 
date primarily by the private sales of equity securities pursuant to which the
Company received approximately $12,123,000 and by bank term notes to finance
purchases of equipment. Since inception, the principal uses of cash have been to
fund research and development of the Company's products and initial marketing of
the products and to purchase capital equipment. As of September 30, 1996, the
Company had $2,163,000 in accounts receivable.
 
     At September 30, 1996, the Company's bank indebtedness, consisting of
equipment lines of credit amounted to $823,000, payable in monthly installments.
Future principal payments are $101,000, $347,000, $252,000, $99,000 and $24,000
for the remainder of 1996 and annually for 1997, 1998, 1999 and 2000,
respectively. Interest accrues on such loans at the bank's prime rate (8.25% at
September 30, 1996) per annum. The proceeds of such loans were used by the
Company to acquire capital equipment. In September 1996, the Company negotiated
an additional equipment line in the amount of $800,000 under similar terms. The
Company is prohibited from paying cash dividends without the consent of the bank
while there are outstanding borrowings.
 
     As of September 30, 1996, the Company had no material commitments for
capital expenditures.
 
     The Company believes that the net proceeds from the sale of the Common
Stock in this offering, together with existing cash balances, funds available
under the equipment line and funds generated by operations, will be sufficient
to meet its anticipated liquidity and working capital requirements for at least
the next twelve months.

Marketing, Spiegel and USAir.
    
 
INDUSTRY BACKGROUND
 
  Call Center Market
 
     Companies are increasingly recognizing that excellent customer service can
be used as a strategic weapon to differentiate their firms from competitors. In
order to remain competitive, corporations must continually evaluate their
product and service offerings to expand market share, lower costs and meet
customer expectations. To improve service quality, companies have invested in
technologies that enable them to concentrate customer service representatives,
or agents, into groups known as call centers. Many corporations utilize call
centers as the primary method of interacting with their customers. These call
centers are typically deployed in multiple locations and can be utilized to
provide a prioritized level of services for their most valued customers. Call
centers allow businesses to reduce costs and deliver premium customer service.
 
     While call centers have grown both in size and importance, current
technologies have been focused on stand-alone, call center applications, rather
than the customer interaction requirements of the entire corporation. This has
led to a fragmented environment in businesses that have multiple call centers,
branch offices and divisions, with call centers evolving as technology "islands"
within the corporation. As a result, corporations are unable to provide
solutions that utilize all the customer response resources within the
organization whether they are personnel or systems-based. Increasingly,
successful organizations are seeking solutions to address these strategic
business requirements through the implementation of "virtual call centers."
Virtual call centers utilize all the relevant resources maintained by the
corporation in order to achieve a unified, controllable and adaptable customer
service solution. Enterprise-wide utilization of resources and technology
enables the corporation to maximize levels of customer service while fully
utilizing existing investments in telephony, technology and personnel.
 
  Call Center Technology
 
     In response to customer demand, the telecommunications environment has
changed rapidly with the emergence of new carrier-based, Advanced Intelligent
Network (AIN) services and 800/888 number portability. Most interexchange
carriers (IXCs), including AT&T, MCI and Sprint, have opened network control to
their customers, enabling the development of third party sofware to control the
routing of customer calls within their networks. Corporations can now shop for
the most competitive carrier rates and implement new network-based services
which are not based on proprietary closed solutions, while retaining their
existing telephone numbers. As the era of "open public networking" evolves,
corporations are seeking business solutions that encompass more than
 
                                       24
<PAGE>   29
 
the limited, non-integrated, proprietary telecommunication products that have
been dominant in the past.
 
     The technology utilized by call centers has evolved dramatically over the
past three years. Historically, due to the closed nature of public networks,
corporations installed premises-based switching systems at the end of long
distance or local exchange telephone lines. Reliance on these switching systems
requires corporations to use proprietary closed solutions offered by service
providers where multi-vendor switching system interoperability was not possible.
Consequently, the call center solutions employed by most corporations have been
designed around the technological limits of premises-based switching systems and
the limitations of carrier networks, which prevent corporations from realizing
the potential benefits of virtual call centers. Virtual call centers draw upon
all of the organization's call response resources and utilize open-systems based
applications to enhance the capabilities of the existing call center
infrastructure by integrating it with existing business applications and data.
 
     The primary providers of call center solutions are IXCs and Automatic Call
Distribution (ACD) switching system vendors. Currently, the major IXCs offer
services that can route inbound toll-free calls to more than one call center,
but they have limited visibility as to why the call is being delivered to that
location. These services attempt to distribute calls among multiple call center
locations by relying on percentage allocations based on historical data or call
counting. Since there is no real-time data, these routing schemes are limited
because the system is not aware of what is actually taking place in the
individual call centers. For example, carriers might route 40% of a business'
incoming calls to Boston, 30% to Dallas and 30% to Denver using a set table
based on time of day and origin of call. While this solution is viable as long
as each site is staffed accordingly to handle the inflow of calls, it cannot
dynamically adjust to variances in agent availability, call handling times, and
calls from non-network sources. Furthermore, the customer is unable to benefit
from a multi-carrier environment. Many ACD switching system vendors provide
private networking options that allow calls to flow from one system to another,
but these systems consume network bandwidth and still do not optimize network
resources. They are also ineffective in a multi-vendor ACD environment.
 
     Due to the migration towards open systems by the IXCs, customers are now
able to control connections across interexchange carrier networks based on
resources, customer profiles and other factors as determined by high-end
enterprise-level software applications. ACDs and other customer premises-based
switching systems have also opened control to computer applications. The
evolution of Computer Telephony Integration (CTI) technology allows computer
applications to interface with and control functions of the ACD or Private
Branch Exchange (PBX). These applications are capable of utilizing business
data, legacy systems and client/server systems and integrating them with
existing telecommunications systems.
 
     To date, few organizations have fully realized the potential benefits
offered by virtual call centers due to the lack of enterprise-wide call
distribution. In particular, the need for enterprise-wide call distribution must
be addressed as a prerequisite for a well-managed customer-focused call center.
Traditional carrier services and ACD products have limited flexibility and are
generally not scalable to large enterprises. These solutions do not facilitate
enterprise-wide call distribution since they offer only local routing within a
stand-alone ACD, and do not enable a multi-vendor, multi-carrier solution. As a
result, the Company believes that the need exists for flexible, scalable,
customer premises-based call processing software that will manage the control of
customer-based switching systems, network routing, call queuing and voice
services.
 
GEOTEL SOLUTION
 
     GeoTel's solution allows companies that utilize call center technology to
deliver cost-effective, premium customer service. The Company's Intelligent
CallRouter (ICR) enables enterprise-wide call routing and consolidated real-time
management information at the network level. These
 
                                       25
<PAGE>   30
 
capabilities are independent of the manufacturer of the ACD, PBX or key system
to which they are attached. The ICR also provides interfaces to multiple carrier
networks enabling call routing independent of the toll-free network provider.
The following diagram illustrates how the ICR connects geographically dispersed
agent groups into a single virtual call center.
                                   [DIAGRAM]
 
     The ICR extends a corporation's existing public and private network
solutions with enterprise-wide, intelligent call processing directed at
organizations that utilize call center technologies to interact with their
customers. The ICR allows corporations to blend the logic of both the carrier
network and ACDs as well as business applications required to provide high-level
customer service and customer contact support. By integrating all call center
applications, a corporation can achieve large group efficiencies, such as
utilizing available agents regardless of location, instead of physically adding
staff to a specific call center. To achieve enterprise-wide call control, the
ICR has visibility of all call answering resources, enabling the system to route
calls and associated data transactions to the agent or skill group that best
satisfies the rules established by the corporation. The ICR connects all call
centers into a hierarchical, networked system, so that an enterprise routing
application can receive the real-time status information required to control
call transactions throughout the enterprise.
 
     The Company's solutions offer the following advantages:
 
     Virtual Call Center.  The ICR transforms geographically dispersed agent
groups connected to different ACDs and VRUs into a single virtual team, reducing
the number of agents required for a given service level, while offering a more
uniform level of service to all callers. Since labor is a significant cost for
service-oriented corporations, the ability to utilize agent resources more
effectively provides a significant cost savings for the Company's customers. In
addition, the ICR allows local ACD capabilities to be extended to the entire
network. Sophisticated enterprise-wide call routing routines, such as those
using customer account numbers or Automatic Number Identification (ANI), can be
developed once and deployed at either the network level or in conjunction with
an ACD or VRU at the customer's premises, or both.
 
                                       26
<PAGE>   31
 
     Multiple Carrier and Switch Interoperability.  The Company's open solution
does not require the customer to replace its existing premises-based equipment,
switches or carriers, therefore extending their value in a "plug-and-play"
environment. The Company's customers are also able to select among AT&T, MCI or
Sprint, offering them the ability to leverage new features and cost saving
opportunities from the major 800 providers. In addition, the ICR allows
customers to remain vendor independent by supporting the major ACD
switches -- Lucent DEFINITY(@), Aspect CallCenter(@), Northern Telecom
Meridian(TM), Rockwell Galaxy(TM) and Rockwell Spectrum(TM).
 
     Real-Time Routing.  The routing of customer calls is a real-time,
mission-critical application. The ICR's Pre-Routing feature is the application
of ACD-like call routing at the network level, before the caller hears ringing
and before the call is sent to a given destination. Unlike any currently
available call routing service offered by carriers, the Pre-Routing feature can
route calls based on real-time knowledge of agent availability and queue status,
not on a fixed percentage or allocation basis. The ICR recognizes where the call
originates, gathers real-time information about the status of all call centers
and agents, and then routes calls based on best available enterprise-wide
capabilities and resources at the moment the call is received. Post-Routing is
the control of calls already connected to an ACD or PBX, such as the intelligent
transfer of calls from Voice Response Units (VRUs), agent-to-agent transfers and
the overflow of calls between call centers. These capabilities enable the ICR to
route calls on an individual call basis, across different ACDs and multiple
carriers.
 
     Fault Tolerant Open Architecture.  The ICR is designed to be fault tolerant
to hardware component failures, communications network failures, asynchronous
software errors and the catastrophic loss of a site supporting the ICR. The
Company's technology utilizes an open architecture and is based on industry
standard software, such as Windows NT, SQL Server and PowerBuilder. The ICR has
been designed to integrate with existing call center applications and facilitate
support of future applications. The Company has defined and published
application programming interfaces for major call center applications such as
workforce management, interactive VRUs and customer databases.
 
     Consolidated Management Reporting.  The Company's call routing solution
enables customers to manage their distributed call centers with consolidated,
real-time and historical reporting. The ICR provides the ability to access and
combine data from multiple databases, allowing the user to source best-of-class
applications for call volume forecasting, agent scheduling, workflow management
and screen-synchronization while maintaining an enterprise-wide view of the
performance of their call centers.
 
STRATEGY
 
     The Company's primary business objective is to become the leading supplier
of enterprise-wide call distribution software solutions. To achieve this
objective, the Company is pursuing the following strategies:
 
     Extend Technology Leadership.  Capitalizing on the Company's experience in
call centers, communications and software technologies, the Company was the
first to deliver a client/server-based application solely focused on
enterprise-wide call distribution. The Company intends to continue to utilize
and integrate industry available technologies whenever appropriate and focus its
development resources on expanding the value-added call processing features
required by its customers. The Company believes it distinguishes itself through
its portfolio of supported ACDs, multi-carrier connectivity, product
adaptability to business environments, implementation of industry standards,
open systems platforms, scalability and product integration with most call
center applications.
 
     Expand Enterprise Call Distribution.  GeoTel intends to ensure that its
call distribution technology continues to expand to include all of the answering
resources available within a customer's business environment. This will include
high-end production call centers, VRUs and distributed call answering resources
including branch offices, remote agents and professionals,
 
                                       27
<PAGE>   32
 
network resources and desktop applications. In June 1996, GeoTel delivered and
installed ICR release Version 1.4 which includes support for the integration of
VRUs. By integrating VRU systems, the Intelligent CallRouter extends routing
control to network and premise VRUs, allows the corporation to use VRUs as an
intelligent call answering resource in the virtual call center, and provides
consolidated management information of VRU data. Intelligent CallRouter
applications have been implemented in systems supporting as few as 200 and as
many as 5,000 call center agents.
 
     Leverage Open Architecture.  The Company continues to develop interfaces to
both existing and emerging call center technologies provided by the vendors of
market-leading technologies. The Company intends to provide its customers with
the ability to protect their investment in current call center solutions, while
providing value-added services and functionally beyond their existing
infrastructure. This will be accomplished by adhering to open industry standard
interfaces of other vendor products and publishing interfaces to the Company's
call routing software platform for products and services such as ACDs, carrier
networks, interactive VRUs and customer databases.
 
     Utilize Multiple Distribution Channels.  The Company has established a
multi-channel distribution system to cost-effectively address the potential
market for its products. To date, the Company has generated the majority of its
revenues through its direct sales force which maintains frequent customer
contact and knowledge of customer applications. The Company's direct sales force
is complemented by strategic sales channels, including its relationship with
MCI, selected resellers and an international partner. The Company intends to
expand both direct and indirect distribution channels and to penetrate
international markets by expanding its relationships with the market leaders of
toll-free services on a country-by-country basis.
 
     Ensure Customer Success.  GeoTel believes that superior customer service,
support and training are essential for customer satisfaction and are key to
differentiating its overall product offering. The Company offers consulting and
installation services to assist customers in designing and deploying call
routing applications and also provides training for end-users and distribution
partners. GeoTel intends to expand its own customer service, support and
training activities, as well as to encourage third-party organizations, such as
international partners, to become proficient in deploying the Company's
products.
 
PRODUCTS
 
     The GeoTel Intelligent CallRouter is an advanced call-by-call routing
server that supports multiple call routing clients independent of their
location, ACD, IXC or VRU. The multi-carrier, multi-vendor capabilities of the
ICR allow the user to focus on delivering premium customer service without the
limitations of proprietary or custom-developed solutions. The ICR combines
real-time call routing capabilities with an extensive management reporting
system. Its open architecture enables interoperability with other call
processing and call volume management systems within an enterprise and provides
a means for integrating those various stand-alone solutions. The ICR can be
interfaced to agent scheduling, workflow management and other call center
management tools. The distributed software fault tolerance implemented in the
Intelligent CallRouter provides the mission-critical reliability required for
enterprise-wide call distribution.
 
     The principal function of the ICR is to route telephone calls among
geographically distributed call centers in a way that optimizes the use of
resources across all call centers or other answering locations. In order to
perform these functions, the ICR utilizes network-based information on the
origin of the call and information provided by the caller to match the caller
with the skills of the available answering resources. The primary components of
the ICR are a central routing controller, a database, and interfaces to the
telephone network and call answering devices such as PBXs, ACDs and VRUs.
 
     The ICR is an open systems product that has been deployed on
industry-standard platforms. The Company designed the system to support a broad
range of intelligent telecommunications interfaces, industry standard MIS tools,
computer platforms and a growing number of vertical market
 
                                       28

applications. The ICR uses Windows NT as the core multitasking operating
environment. Windows NT allows customers to select from a variety of hardware
platforms certified by the Company on which to deploy the ICR application. The
database utilized by the ICR is Microsoft SQL Server for Windows NT, which
provides an advanced, client/server database management system. The Company
provides a monitoring and reporting system based on PowerBuilder, which is a
Windows-based, client-server application development tool. PowerBuilder allows
users to quickly and easily build sophisticated, graphical applications that can
access information stored in multiple databases. Since the Company utilizes a
database technology that is open database connectivity (ODBC) compliant, the
customer may choose a reporting tool of its preference as an alternative to
PowerBuilder. The following diagram illustrates the principal components of the
ICR. The components included in the ICR provided by the Company are the
CallRouter, Network Interface Controller, Peripheral Gateway, Database Server
and AWS (Admin Workstation).
 
                                   [DIAGRAM]
 
     The major components of the ICR are as follows:
 
     CallRouter.  The core of the Intelligent CallRouter is a suite of software
processes called the CallRouter that provides the central intelligence by which
customers translate business goals into call routing decisions. The CallRouter
receives and responds to routing requests from the routing clients (Network
Interface Controllers and Peripheral Gateways), collects call center event
activity from the Peripheral Gateways and communicates with users through
desktop Admin Workstations. The CallRouter provides all the routing choices
available in today's ACDs and applies them at the network level. The
implementation of routing services on an enterprise basis creates a call center
management model where geographically distributed call centers appear as if they
were at one location. The ICR utilizes real-time, event-driven data such as
agent status, queue status, and incoming call volume in making its call-by-call
routing decisions. It allows customers to establish routing decisions for a wide
range of agent and service performance metrics, including agent availability,
the ratio of calls in progress to logged-in/ready agents, and the ratio of calls
in queue to staffed/scheduled agents. The CallRouter makes routing decisions
through user-defined call routing scripts. The logic required to segment
callers, identify their reason for calling, and then forward
 
                                       29
<PAGE>   34
 
those requests for service to the appropriate agent(s) is defined in call
routing objects. Having determined these routing guidelines, business rules are
defined to arbitrate between routing options where the demand for a given skill
or service resource exceeds availability. Threshold parameters can be input to
allow for the use of backup agents under certain circumstances or to prioritize
call handling of a given class of caller.
 
     Network Interface Controller (NIC).  The NIC is the software interface
between the Intelligent CallRouter and the interexchange carrier network. It
communicates with the IXC network through the intelligent network control
interfaces that have recently been made available by the carriers. The NIC
receives call routing requests from the network, forwards them to the
CallRouter, and returns responses to the carrier network. In effect, the NIC
transforms the network into a routing client. This approach allows customers to
control routing decisions at the network level and gain greater flexibility as
they seek to further deploy advanced intelligent network services.
 
     Peripheral Gateway (PG).  The PG software provides the interface between
the CallRouter and the call center system (ACD, PBX, or VRU) that is being
monitored and/or controlled by the ICR. The PG connects to the CTI link and/or
ACD's management reporting system and obtains information regarding agent
availability, agent performance, the number of calls in progress, and how they
are being handled. To facilitate Post-Routing, the PG can also exert control
over the ACD, PBX or VRU and instruct it where to route calls.
 
     Database Server.  GeoTel's database technology reduces the performance
constraints normally associated with ACD and network data aggregation. Operating
in conjunction with the CallRouter, the ICR's Database Server stores and manages
historical information, including Pre-Routing and Post-Routing records, routing
scripts, and ICR configuration data. The ICR Database Server is a relational
database that can collect and process large amounts of call and transaction
data, including call handling, planning and performance data.
 
     Admin Workstation.  The Intelligent CallRouter records call activity on an
enterprise-wide basis and reports on this activity on a real-time basis
utilizing the Admin Workstation. In addition to providing real-time call
handling statistics, the ICR provides consolidated, historical reporting for all
calls across all attached networks, ACDs, PBXs, and VRUs. Using any desktop
workstation within the network, customers can mix and match data in virtually
any combination, allowing analysis of real-time data with historical data. For
example, customers may want to compare current performance to past performance
over the last few minutes, days, or weeks.
 
     Software license fees for the Intelligent CallRouter vary significantly
based on a number of factors, including the functionality of the system, the
number of sites, the number of agents at each site and the level of redundancy
required. The customer list price for software license fees for the Intelligent
CallRouter software typically range from approximately $420,000 for a three site
configuration with some redundancy to approximately $1,000,000 for an eight site
configuration with extensive redundancy. The Company typically provides
discounts based on volume purchases. The Company and its customers generally
enter into maintenance agreements providing for ongoing service and product
upgrades for a fixed annual fee. Maintenance services and installation services,
which are not included in the license fee, amount to an additional 15% and 10%,
respectively, of the list price license fee. Maintenance contracts are renewable
on an annual basis.
 
TECHNOLOGY
 
     The Company has developed a number of innovative technologies to support
its open strategy:
 
     Real-Time Routing.  The ICR's real-time delivery of enterprise-wide call
center data makes use of innovative Local and Wide Area Network (LAN/WAN)
solutions to efficiently distribute information and facilitate connectivity. A
mixed LAN/WAN environment is supplemented by dial capabilities for both casual
access of data from remote premises as well as alarm notification and paging.
All clients are configured with redundant data paths to central services for
both configuring and
 
                                       30
<PAGE>   35
 
monitoring the enterprise. The system is designed to run on single or multiple
Windows NT server-class machines. Interprocess communication is efficient based
on native capabilities within Windows NT integrated with the Company's
processes. The architecture can scale to support very large numbers of agents,
small offices, and home agents.
 
     Fault Tolerance.  To meet rigorous requirements for system reliability in
the call processing market, the Company has developed innovative industry
standard fault tolerant software solutions to provide not only tolerance of
hardware, software and communications failures, but also for the loss of an
entire site. The Company's software technology relating to virtual time
synchronization provides fault tolerance at the process level and includes
protection against single-point hardware failures. Detection of failures is
immediate and the Company has augmented standard TCP/IP protocols with features
designed to minimize outages due to communications failures.
 
     Remote Support and Diagnostics Technology.  The ICR incorporates extensive
system management capabilities, including alarming with automatic "phone home"
and paging capabilities; symmetric database replication; intelligent PC Server
node management; and tools to provide graphical representations of system
status. Consistent with an open architecture, the system will export Simple
Network Management Protocol (SNMP) "traps" to management systems. Fully
redundant communications paths are enhanced with real-time detection of
communications failures with near instantaneous switch-over to redundant links.
 
     Carrier Connectivity.  The ICR meets the certification standards of all
three of the major U.S. interexchange carrier networks, AT&T, MCI and Sprint, by
interfacing with the SS7, UDP/IP, and X.25 networks, respectively, using the
proprietary protocols of each carrier. The ICR architecture is designed to
support the introduction of other network interfaces as the Telecommunications
Act of 1996 enables the entry of other providers into the toll-free marketplace.
In addition, the Company is developing interfaces for several international
carriers.
 
     Premises-based Switching/Call Processing lnterfaces.  The Company has
developed event-based interfaces to all of the major ACDs. The ICR currently
supports five switches: Lucent DEFINITY, Aspect CallCenter, NTI Meridian,
Rockwell Galaxy and Rockwell Spectrum. By developing event-based tracking of the
ACDs (detecting when any event of interest happens at the ACD), the ICR has the
capability to report accurate enterprise-wide statistics and know accurately
which agents are available and skilled to handle incoming calls. The ICR can
also control, via Post-Routing, how calls directed to or from the switch are
subsequently routed and has the ability to deliver CTI information. By designing
the ICR to have the capability to interface to all ACDs, PBXs, VRUs, and other
premises-based equipment, the ICR enables customers to utilize equipment from
multiple vendors allowing effective use of a multi-vendor switching environment.
In contrast, proprietary solutions require all switches to be purchased from the
same vendor.
 
     Visual Script Editor.  The ICR uses visual/object-based call routing
scripts controlled and defined by the customer. The Visual Script Editor is used
to describe how calls are to be routed on a call-by-call basis. Each dialed
number can have a unique treatment or can be handled with a collection of other
dialed numbers. Many scripting objects are defined to assist the script designer
in choosing an appropriate algorithm. The Database Lookup and Application
Gateway objects enable the Script editor to import, in real-time, external
database information or arbitrary data that can be used in subsequent script
objects.
 
CUSTOMERS
 
     The Company provides its software and services to customers in a variety of
industries. The Company's typical customers are large, high volume users of
toll-free services that conduct a significant portion of their interaction with
their customers using the telephone. The Company announced the Intelligent
CallRouter in August 1994. As of September 30, 1996, the Company had licensed
its products to over 20 companies directly or through its distribution partners.
These customers include some of the largest users of toll-free services in the
world. The Company believes
 
                                       31
<PAGE>   36
 
that the following list is representative of its target customers by virtue of
call volume, industries represented and the required business applications:
 
<TABLE>

    Household Credit Services                 USAir
</TABLE>
 
     Fidelity, Sprint and America Online accounted for approximately 38.3%,
25.9% and 20.0%, respectively, of the Company's total revenues in 1995, and
Fidelity, Optus, GTE Communications Systems Corporation, MCI and USAir accounted
for approximately 19.7%, 15.9%, 10.2%, 8.7% and 7.7%, respectively, of the
Company's total revenues for the nine months ended September 30, 1996.
 
     A description of certain customer relationships follows:
 
     MCI.  MCI Telecommunications Corporation is one of the largest and fastest
growing diversified communications companies in the world. The Company has
entered into a three-year agreement with MCI, whereby MCI will offer the
Company's products as a network service within MCI's set of call center
solutions. Under the terms of the agreement, MCI's Call Center Division will
deploy the Company's products as a component of MCI's expanded network-based,
call center technology offerings. Additionally, the MCI worldwide sales force
offers a call center solution incorporating the Company's products. The
agreement requires MCI to make certain minimum purchases during the three year
term and may be terminated by either party upon thirty days' notice in the event
of a material default by the other party.
 
     Spiegel.  Spiegel is a leading multi-channel specialty retailer. While
catalogs remain its primary distribution channel, Spiegel also markets
merchandise through over 400 Eddie Bauer stores. Spiegel's goal is to provide
excellent customer service through more efficient call center management,
increased agent productivity, and improved load balancing across business units.
Spiegel uses the Company's products to route 20 million yearly calls to its
approximately 1,300 agent stations, located in three geographically dispersed
call centers. Spiegel is using the Company's products in a mixed ACD/VRU
environment to reduce its average speed of answer and automatically balance
loads. The Company has entered into an agreement with Spiegel pursuant to which
Spiegel was granted a non-exclusive, perpetual license to use the Company's
products in exchange for a one-time license fee. The agreement may be terminated
by Spiegel or by the Company if Spiegel fails to comply with the terms of the
agreement.
 
     USAir.  USAir is one of the world's largest airlines with 4,800 daily
flights servicing over 160,000 passengers. It operates 11 call centers, with
4,000 agents who handle between seven to eight million inbound calls each month.
The Company's products are used in a multi-carrier environment to make routing
decisions based on factors such as agent availability, load balancing across
centers, and data contained in USAir's customer database. The Company has
entered into an agreement with USAir pursuant to which USAir was granted a
non-exclusive, perpetual license to use the Company's products in exchange for a
one-time license fee. The agreement may be terminated by the Company if USAir
fails to comply with the terms of the agreement.
 
     A significant portion of the Company's revenues to date have been derived
from initial license fees from customers who have acquired fully-paid licenses
to the installed product. None of the Company's customers, other than MCI and
Optus, is contractually obligated to license or purchase additional products or
services from the Company and there can be no assurance that revenues from these
customers will continue or, if continued, will reach or exceed historical levels
in any future period. Service revenues represent an insignificant portion of the
Company's revenues to date.

SALES AND MARKETING
 
     The Company's distribution strategy is to sell its software products and
services to major corporations who are significant users of inbound toll-free
services, and have multiple locations with resources that respond to incoming
calls. The Company uses a direct sales force in the United States as its primary
distribution channel to market to these companies. There are currently nine
direct sales representatives located in eight offices throughout the U.S. Each
sales representative carries a quota for a defined geographic territory and is
compensated for all sales within the territory. The Company's sales strategy is
based on a consultative sales process, working closely with customers to
understand and define their needs and determine how they can be addressed by the
Company's products. This strategy continues after the initial sale. The Company,
through ongoing sales, support, training, and maintenance, maintains close
contact with its existing customers in order to determine the customers'
evolving requirements for updates and enhancements.
 
     In addition to the direct sales organization, the Company has signed
agreements with MCI, Optus and Rockwell Switching Systems Division to complement
direct sales and provide international distribution. MCI has signed a three-year
renewable agreement with the Company to offer its products as a service to
customers on a worldwide basis. Optus is a distributor of the Company's products
in the Australian and New Zealand markets. To complement its domestic sales
strategy, the Company intends to develop its sales channels for its products in
the international markets. The Company plans to continue to address
international markets by using its direct sales force and expects to add several
other distribution partners.
 
     The Company supports its distribution strategy with a variety of focused
marketing activities designed to identify qualified prospects and expand the
Company's reputation. The Company attends several industry trade shows, conducts
numerous informational seminars in different cities, regularly speaks at
industry events, publishes articles and white papers, and uses direct mail. In
addition, the telecommunications marketplace is heavily influenced by reference
accounts and, as such, the Company is dependent upon its existing customers for
favorable references.
 
     As part of its marketing and product strategy, the Company cultivates
relationships with the major ACD/PBX vendors and VRU vendors, as well as the
interexchange carriers. Equipment from each of the ACD/PBX vendors is maintained
at the Company's facilities and technical discussions are ongoing to ensure
tight integration with the various switches. The Company intends to continue to
expand the range and number of products it supports based on customer requests
and market opportunities.
 
CUSTOMER SERVICE AND SUPPORT
 
     The Company believes that high quality customer service and support are
integral components of the solutions it offers. The Company's customer service
and support organization provides customers with technical support, training,
consulting and implementation/installation services. The Company believes that
in order to meet its customers' support expectations it must invest in and
leverage technology to build its service infrastructure. As of September 30,
1996, the Company had 12 employees in its customer service and support
organization. All of the Company's customers currently have software maintenance
agreements with the Company that provide for one or more of the following
services:
 
     Software Maintenance and Support.  The Company's support organization
offers a variety of support services to its customers including telephone,
electronic mail and facsimile customer support through its support services
staff. In addition, the product provides a "call home" application which allows
customers to request service on-line. Initial product license fees do not cover
software maintenance. Through its standard customer support package, the Company
provides its customers with 12-hour weekday telephone support and 24-hour
monitoring and quick response through use of the Company's remote support
technology. Periodic product updates and mainte-
 
                                       33
<PAGE>   38
 
nance releases are included with the annual support fees for the company's
standard support package, which is 15% of the then-current list price of the
licensed products.
 
     Documentation and Training.  The Company provides each customer with
product design, documentation and training. The product includes an easy-to-use
graphical user applications interface with on-line help. A complete library of
end-user documentation is also provided with each system. The Company offers
comprehensive training courses in all aspects of the product at its facility in
Littleton, Massachusetts, and at the customer's option, provides on-site
customer training upon request. Fees for education and training services, beyond
those services provided as a part of installation services, are in addition to
and separate from the license fees charged for the Company's software products
and are charged per student, per class or on a time and materials basis.
 
     Consulting.  The Company's application consultants are available to work
closely with customers to provide assistance concerning application design and
report customization. Fees for consulting services are charged separately from
the Company's software products on a time and materials basis. In addition, the
Company intends to continue to develop relationships with third-party consulting
organizations in order to support its customer base.
 
     Installation Services.  The Company provides customers with comprehensive
installation services, including initial application design, implementation
planning, system design support, project management, initial education and
training, and coordination of third-party software and hardware acquisition. The
Company's fee for installation services is charged separately from the Company's
licensing fees and is based on a percentage of the current list price of the
products being installed. Fees for the Company's standard installation services
are typically 10% of the then-current list price of the licensed products.
 
PRODUCT DEVELOPMENT
 
     Since its inception, the Company has made substantial investments in
product development. The Company's development organization was built upon a
base of software professionals with extensive experience in operating systems,
communications, fault tolerance, and software quality processes. Customer
experience and direct input to the product planning process is reflected in all
products designed and delivered by the Company.
 
     The Company announced the Intelligent CallRouter in August 1994 and began
customer shipments in May 1995. The Company plans to introduce enhancements to
the Intelligent CallRouter and new products that can be sold to existing and new
customers. The Company is currently working on several strategic projects that
will enhance the ICR product in the areas of desktop integration, computer
telephony integration, and the use of the Internet and Intranets. There is also
a significant emphasis on enhancing the product to work in international
markets.
 
     The Company intends to expand its existing product offerings and introduce
new products for the call processing software market. Although the Company
expects that most of its new products will be developed internally, the Company
may, based on timing and cost considerations, acquire technology and products
from third parties and evaluate third-party applications for inclusion within
its products on an ongoing basis. The Company believes that its future
performance will depend, in large part, on its ability to maintain and enhance
its current product line, develop new products that achieve market acceptance,
maintain technological competitiveness, meet an expanding range of customer
requirements and continue to recruit highly-skilled and qualified software
professionals. See "Risk Factors -- Dependence on New Products and Rapid
Technological Change."
 
   
     As of September 30, 1996, the Company's product development, quality
assurance and technical writing staff consisted of 28 employees. The Company's
total expenses for research and development for fiscal years 1993, 1994, 1995
and the nine months ended September 30, 1996 were $140,000, $1,879,000,
$2,322,000 and $2,210,000, respectively. The Company anticipates that it will
continue to commit substantial resources to research and development in the
future and that product
    
 
                                       34
<PAGE>   39
 
development expenses may increase in absolute dollars in future periods. To
date, the Company's development efforts have not resulted in any capitalized
software development costs.
 
COMPETITION
 
     The market for telecommunications software products is intensely
competitive and is subject to rapid technological change. Although to date the
Company has experienced limited competition, the Company expects competition to
increase significantly in the future. Currently, the Company's principal
competitors are the interexchange carriers, particularly AT&T, and to a lesser
extent MCI and Sprint, which provide proprietary call routing solutions as part
of their service offerings. In addition, a number of other companies have
introduced or announced their intention to introduce products that could be
competitive with the Company's products, including Genesys Telecommunications
Laboratories and IEX Corporation. Additional competitors, including traditional
ACD providers, such as Lucent Technologies, Aspect Telecommunications
Corporation, Northern Telecommunications, Inc. and Rockwell International
Corporation, may enter the market by enhancing their proprietary private network
solutions or by entering into arrangements with the interexchange carriers. The
Company believes that, to date, approximately one-half of the Company's
customers have purchased the Company's products to replace or enhance existing
call routing solutions offered by the interexchange carriers. The Company's
other customers have purchased the Company's products in order to implement a
virtual call center solution for the first time. This additional competition
could adversely affect the Company's sales and profitability through price
reductions, reduced gross margins and loss of market share. In particular,
should one or more interexchange carriers, including MCI, Optus and Sprint which
are customers of the Company, choose to provide or distribute competitive
products and services, the Company's business could be materially adversely
affected. Many of the Company's current and potential competitors have
substantially greater financial, marketing and technical resources than the
Company. See "Risk Factors -- Competition."
 
     The Company believes that the principal competitive factors affecting its
market include product performance and functionality, customer service and
support, product reputation, company reputation, carrier support, ACD support,
fault tolerance, adaptability to individual customer call routing requirements,
scalability, ability to integrate with third party products, ease-of-use, price,
and effectiveness of sales and marketing efforts. Although the Company believes
that it currently 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 greater financial,
marketing, service, support, technical, and other resources than the Company.
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
     The Company relies primarily on a combination of patent, copyright,
trademark and trade secrets laws, as well as confidentiality agreements to
protect its proprietary rights. The Company has been issued one patent relating
to the architecture, operating methodologies and interfaces of the Company's
Intelligent CallRouter. The Company also has one patent application pending in
the United States and internationally. While the Company believes that its
pending patent application relates to a patentable invention, there can be no
assurance that such patent application or any future patent application will be
granted or that any patent relied upon by the Company will not be challenged,
invalidated or circumvented, or that rights granted thereunder will provide
competitive advantages to the Company. Moreover, despite the Company's efforts
to protect its proprietary rights, unauthorized parties may attempt to copy
aspects of the Company's products or to obtain the use of information that the
Company regards as proprietary. In addition, the laws of some foreign countries
do not protect the Company's proprietary rights to as great an extent as do the
laws of the United States. There can be no assurance that the Company's means of
protecting its proprietary rights will be adequate or that the Company's
competitors will not independently develop similar technology.
 
     The Company is not aware that any of its products infringes the proprietary
rights of third parties. There can be no assurance, however, that third parties
will not claim infringement by the
 
                                       35
<PAGE>   40
 
Company with respect to current or future products. The Company expects that
software product developers will increasingly be subject to infringement claims
as the number of products and competitors in the Company's industry segment
grows and the functionality of products in different industry segments overlaps.
Any such claims, with or without merit, could be time-consuming, resulting in
costly litigation, cause product shipment delays or require the Company to enter
into royalty or licensing agreements. Such royalty or licensing agreements, if
required, may not be available on terms acceptable to the Company, if at all,
which could have a material adverse effect upon the Company's business,
operating results and financial condition.
 
     The software and network adapter necessary to enable the Company's
Intelligent CallRouter to interface with the AT&T network is licensed by the
Company from a single vendor under a perpetual, fully-paid license. Although the
Company has access to the source code underlying this software and rights to
manufacture the network adapter, if for any reason the vendor does not make the
software or network adapter available to the Company, there can be no assurance
that the Company will be able to develop these products on a timely basis.
 
EMPLOYEES
 
     As of September 30, 1996, the Company had a total of 65 employees, all of
whom are based in the United States. Of the total, 28 were in research and
development, 12 were in support and support services, 18 were in sales and
marketing and 7 were in administration and finance. The Company's future
performance depends in significant part upon the continued service of its key
technical, sales and marketing, and senior management personnel and its
continuing ability to attract and retain highly qualified technical, sales and
marketing, and managerial personnel. Competition for such personnel is intense
and there can be no assurance that the Company will be successful in attracting
or retaining such personnel in the future. None of the Company's employees are
represented by a labor union or are subject to a collective bargaining
agreement. The Company has not experienced any work stoppages and considers its
relations with its employees to be good. See "Risk Factors -- Management of
Growth; Dependence Upon Key Personnel."
 
FACILITIES
 
     The Company's executive offices are located in Littleton, Massachusetts in
a facility consisting of approximately 14,000 square feet, under a lease which
expires in December 1998. In addition, the Company leases office space in the
metropolitan areas of Atlanta, Chicago, Dallas, Phoenix and Washington, D.C.
Management believes that its current facilities will not meet its needs through
the next twelve months. The Company is evaluating alternatives for additional
space and believes that suitable additional space will be available to
accommodate expansion of the Company's operations on commercially reasonable
terms.

STOCK PLANS
 
     1993 Restricted Stock Purchase Plan.  The 1993 Restricted Stock Purchase
Plan (the "1993 Plan") was adopted by the Board of Directors in October 1993 and
approved by the stockholders of the Company in December 1993. A maximum of
1,324,063 shares of Common Stock may be issued and sold pursuant to the 1993
Plan. Under the 1993 Plan, shares of Common Stock may be sold to directors,
officers, consultants and other key personnel of the Company (collectively
"Participants") at a purchase price determined by the Compensation Committee of
the Board of Directors. As of September 30, 1996, 986,143 shares of Common Stock
were outstanding under the 1993 Plan. All shares sold pursuant to the 1993 Plan
are subject to repurchase by the Company at the original purchase price for up
to a period of five years from the date of purchase, unless the shares become
"vested" under the terms of the 1993 Plan. None of the shares become vested
until the first anniversary of the date of purchase by the Participant. A
Participant vests in twenty percent of the shares on the first anniversary of
the date of purchase and, thereafter, the remaining shares become vested on a
monthly basis through the fifth anniversary of the date of purchase. In the
event of a change in control, if the Participant has been employed by the
Company for at least six months, an additional twenty percent of the shares held
by the Participant pursuant to the 1993 Plan will become vested shares, unless
such change in control has not been approved by the Board of Directors, in which
event all shares held by the Participant pursuant to the 1993 Plan will become
vested shares.
 
     1995 Stock Option Plan.  The 1995 Stock Option Plan (the "1995 Plan") was
adopted by the Board of Directors in September 1995 and approved by the
stockholders of the Company in January 1996. A maximum of 1,474,726 shares of
Common Stock may currently be issued pursuant to the 1995 Plan upon exercise of
options. The number of shares of Common Stock available for grants under the
1995 Plan will be increased by the number of shares repurchased by the Company
from time to time under the 1993 Plan. The maximum number of shares will
increase, effective January 1, 1997 and each January 1 thereafter during the
term of the 1995 Option Plan, by an amount equal to four percent of the total
number of shares of Common Stock issued and outstanding as of the close of
business on December 31 of the preceding year. No more than an aggregate of
6,000,000 shares of Common Stock may be issued pursuant to the exercise of
options granted under the 1995 Plan. Under the 1995 Plan, incentive stock
options may be granted to employees and officers of the Company and
non-qualified stock options may be granted to consultants, employees and
officers of the Company.
 
     The 1995 Plan is administered by the Compensation Committee of the Board of
Directors, subject to the supervision and control of the entire Board. Subject
to the provisions of the 1995 Plan, the Compensation Committee has the authority
to select optionees and determine the terms of the options granted, including
(i) the number of shares subject to each option, (ii) when the option becomes
exercisable, (iii) the exercise price of the option (which in the case of an
incentive stock option cannot be less than the fair market value of the Common
Stock on the date of grant, or less than 110% of fair market value in the case
of employees or officers holding 10% or more of the voting stock of the
Company), (iv) the duration of the option, and (v) the time, manner and form of
payment upon exercise of an option.
 
     Options granted under the 1995 Plan vest and become exercisable starting
one year after the date of grant, with twenty percent of the shares subject to
an option becoming exercisable at that time and 1/60th of the shares subject to
the option becoming exercisable each month thereafter. The Option Agreements
governing options granted under the 1995 Plan provide that in the event of a
change in control, if the optionee has been employed by the Company for at least
six months, an additional twenty percent of the options held by the optionee
will vest and become immediately exercisable, unless such change in control has
not been approved by the Board of Directors, in which event all options will
vest and become immediately exercisable.
 
                                       40
<PAGE>   45
 
     An option is not transferrable by the optionee except by will, by the laws
of descent and distribution or pursuant to a qualified domestic relations order.
Options are exercisable only while the optionee remains in the employ of the
Company or for a short period of time thereafter. If an optionee becomes
permanently disabled or dies while in the employ of the Company, the option is
exercisable prior to the last day of the sixth or twelfth month, respectively,
following the date of termination of employment. If the optionee leaves the
employ of the Company for any other reason, the option is exercisable for only
thirty days following the date of termination of employment, which time period
may be extended by the Compensation Committee. Options which are exercisable
following termination of employment are exercisable only to the extent that the
optionee was entitled to exercise such options on the date of such termination.
 
     As of September 30, 1996, options to purchase 860,396 shares of Common
Stock were outstanding under the 1995 Plan, of which options to purchase 8,400
shares were then exercisable. As of September 30, 1996, the following executive
officers held options to purchase Common Stock in the amounts indicated: John C.
Thibault (98,750 shares); Timothy J. Allen (30,000 shares); G. Wayne Andrews
(28,000 shares); Louis J. Volpe (163,867 shares); and Steven H. Webber (63,000
shares).
 
     1996 Employee Stock Purchase Plan.  The 1996 Employee Stock Purchase Plan
(the "1996 Purchase Plan") for employees of the Company was adopted by the Board
of Directors and approved by the stockholders of the Company in September 1996.
The 1996 Purchase Plan authorizes the issuance of a maximum of 250,000 shares of
Common Stock pursuant to the exercise of nontransferable options granted to
participating employees.
 
     The 1996 Purchase Plan is administered by the Compensation Committee of the
Board of Directors. All employees of the Company whose customary employment is
20 hours or more per week and have been employed by the Company for at least six
months are eligible to participate in the 1996 Purchase Plan. Employees who own
5% or more of the Company's stock and directors who are not employees of the
Company may not participate in the 1996 Purchase Plan. To participate in the
1996 Purchase Plan, an employee must authorize the Company in writing to deduct
an amount (not less than 1% nor more than 10% of a participant's base
compensation) from his or her pay commencing on January 1 and July 1 of each
year (each a "Purchase Period"). On the first day of each Purchase Period, the
Company grants to each participating employee an option to purchase up to 1,000
shares of Common Stock. The exercise price for the option for each Purchase
Period is the lesser of 85% of the fair market value of the Common Stock on the
first or last business day of the Purchase Period. The fair market value will be
the closing selling price of the Common Stock as quoted on the Nasdaq National
Market. If an employee is not a participant on the last day of the Purchase
Period, such employee is not entitled to exercise his or her option, and the
amount of his or her accumulated payroll deduction will be refunded to the
employee. An employee's rights under the 1996 Purchase Plan terminate upon his
or her voluntary withdrawal from the Plan at any time or upon termination of
employment.
 
     Common Stock for the 1996 Purchase Plan will be made available either from
authorized but unissued shares of Common Stock or from shares of Common Stock
reacquired by the Company, including shares repurchased in the open market.
 
EXECUTIVE INCENTIVE PROGRAM
 
     The Company has adopted a 1996 Executive Incentive Program (the "Incentive
Program") which is available to executive officers and other management
employees of the Company. Under the Incentive Program, participants may receive
specified bonuses based upon the Company's attainment of certain financial
targets and strategic initiatives in 1996 and job performance evaluations. The
Incentive Program also provides that options to purchase an aggregate of 68,217
shares previously granted to the participants, which would otherwise vest on the
fifth anniversary of the
 
                                       41
<PAGE>   46
 
date of grant, will be fully vested on the first anniversary of the date of
grant, subject to the achievement of the foregoing criteria.
 
EMPLOYMENT AGREEMENTS AND CHANGE OF CONTROL ARRANGEMENTS
 
     Messrs. Thibault, Allen, Andrews, Volpe and Webber are parties to change in
control agreements with the Company which provide for salary continuation and
other benefits upon the occurrence of certain events following a change of
control. These events will occur if such person is terminated without cause or
constructively terminated following a change of control. Upon the occurrence of
such events, the Company is required to continue to pay such person his base
salary for a period of twelve months after termination and provide medical
benefits to such person for such period.
 
LIMITATION OF LIABILITY; INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Company's Restated Certificate of Incorporation limits the personal
liability of directors to the Company, and the Company's Amended and Restated
Bylaws provide that the Company shall indemnify the Company's directors and
officers, in each case to the full extent permitted by the Delaware General
Corporation Law, including under circumstances in which indemnification is
otherwise discretionary under Delaware law. See "Description of Capital

 (1) Beneficial ownership is determined in accordance with the rules of the
     Securities and Exchange Commission. In computing the number of shares
     beneficially owned by a person and the percentage ownership of that person,
     shares of Common Stock subject to options held by that person that are
     currently exercisable, or become exercisable within 60 days following

                          DESCRIPTION OF CAPITAL STOCK
 
     Effective upon the closing of this offering, the authorized capital stock
of the Company will consist of 40,000,000 shares of Common Stock, $.01 par value
per share, and 5,000,000 shares of Preferred Stock, $.01 par value per share
(the "Preferred Stock").
 
     The following summary of certain provisions of the Common Stock and
Preferred Stock does not purport to be complete and is subject to, and qualified
in its entirety by, the provisions of the Company's Restated Certificate of
Incorporation as amended and restated upon the closing of this offering (the
"Certificate of Incorporation") which is included as an exhibit to the
Registration Statement, and by the provisions of applicable law.
 
COMMON STOCK
 
     Holders of Common Stock are entitled to one vote per share on matters to be
voted upon by the stockholders. There are no cumulative voting rights. Holders
of Common Stock are entitled to receive ratable dividends when, as and if
declared by the Board of Directors out of funds legally available therefor,
subject to any preferential dividend rights of any then outstanding Preferred
Stock. Upon the liquidation, dissolution or winding up of the Company, holders
of Common Stock share ratably in the assets of the Company available for
distribution to its stockholders, subject to the preferential rights of any then
outstanding Preferred Stock. The shares of Common Stock outstanding upon the
effective date of this Prospectus are, and the shares offered hereby will be,
when issued and paid for, fully paid and nonassessable. The rights, preferences
and privileges of holders of Common Stock are subject to, and may be adversely
affected by, the rights of holders of shares of any Preferred Stock that the
Company may designate in the future.
 
PREFERRED STOCK
 
     After the closing of this offering, the Company's Board of Directors will
have the authority, without further stockholder approval, to issue up to
5,000,000 shares of Preferred Stock in one or more series and to fix the
relative rights, preferences, privileges, qualifications, limitations 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 any series or the designation
of such series. 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, may discourage bids for the Company's Common Stock at a
premium over the market price of the Common Stock and may adversely affect the
market price and the voting and other rights of the holders of the Common Stock.
The Company has no present plans to issue any shares of Preferred Stock.
 
CERTAIN CHARTER, BYLAW AND STATUTORY PROVISIONS AFFECTING STOCKHOLDERS
 
     Classified Board and Other Matters.  The Company's Board of Directors will
be divided into three classes, each of which, after a transitional period, will
serve for three years, with one class being elected each year. Under the
Delaware General Corporation Law, in the case of a corporation having a
classified Board, stockholders may remove a Director only for cause. Advance
notice of stockholder nominations and any other matter to be brought before a
meeting of stockholders will be required to be given in writing to the Secretary
of the Company within the time periods in the Bylaws. The Certificate of
Incorporation provides that special meetings of stockholders of the Company may
be called only by the Board of Directors, the Chairman of the Board of Directors
or the President. The Certificate of Incorporation also provides that no action
required or permitted to be taken at any Annual or Special Meeting of the
Stockholders of the Company may be taken without a meeting, unless the unanimous
consent of stockholders entitled to vote thereon is obtained. The affirmative
vote of the holders of at least 80% of the combined voting power of then
outstanding voting stock of the Company will be required to alter, amend or
repeal the foregoing provisions. The classification of the Board of Directors
and the limitations on the removal of directors and filling of
 
                                       47
<PAGE>   52
 
vacancies could have the effect of making it more difficult for a third party to
acquire, or of discouraging a third party from acquiring, control of the
Company.
 
     Section 203 of Delaware Law.  Following the consummation of this offering,
the Company will be subject to the "business combination" statute of the
Delaware General Corporation Law. In general, such statute prohibits a
publicly-held Delaware corporation from engaging in various "business
combination" transactions with any "interested stockholder" for a period of
three years after the date of the transaction in which the person became an
"interested stockholder," unless (i) the transaction is approved by the Board of
Directors prior to the date the interested stockholder obtains such status, (ii)
upon the consummation of the transaction which resulted in the stockholder
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 by (a) persons who are directors and also
officers and (b) 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) on or subsequent to
such date the "business combination" is approved by the board of directors and
authorized at an annual or special meeting of stockholders, and not by written
consent, by the affirmative vote of at least 66 2/3% of the outstanding voting
stock which is not owned by the "interested stockholder." A "business
combination" includes mergers, asset sales and other transactions resulting in a
financial benefit to the stockholder. An "interested stockholder" is a person
who, together with affiliates and associates, owns (or within three years, did
own) 15% or more of a corporation's voting stock. By virtue of the Company's
decision not to elect out of the statute's provision, the statute applies to the
Company. The statute could prohibit or delay the accomplishment of mergers or
other takeover or change of control attempts with respect to the Company and,
accordingly, may discourage attempts to acquire the Company.
 
     Directors Liability.  The Certificate of Incorporation of the Company
provides that no director shall be personally liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except 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; (iii) acts or omissions in respect of certain unlawful
dividend payments or stock redemptions or repurchases; or (iv) any transaction
from which such director derives improper personal benefit. The effect of this
provision is to eliminate the rights of the Company and its stockholders
(through stockholders' derivative suits on behalf of the Company) to recover
monetary damages against a director for breach of the fiduciary duty of care as
a director (including breaches resulting from negligent or grossly negligent
behavior) except in the situations described in clauses (i) through (iv) above.
The limitations summarized above, however, do not affect the ability of the
Company or its stockholders to seek non-monetary based remedies, such as an
injunction or rescission, against a director for breach of his fiduciary duty
nor would such limitations limit liability under the Federal Securities Laws.
The Company's Amended and Restated Bylaws provide that the Company shall, to the
full extent permitted by the Delaware General Corporation Law, as amended from
time to time, indemnify and advance expenses to each of its currently acting and
former directors, officers, employees and agents arising in connection with
their acting in such capacities.
 
     Certain provisions described above may have the effect of delaying
shareholder actions with respect to certain business combinations and the
election of new members to the Board of Directors. As such, the provisions could
have the effect of discouraging open market purchases of the Company's Common
Stock because they may be considered disadvantages by a shareholder who desires
to participate in a business combination or elect a new director. The existence
of these provisions may have an adverse effect on the market price of the Common
Stock.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock is Fleet Bank.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon completion of this offering, the Company will have 12,840,509 shares
of Common Stock outstanding (assuming no exercise of outstanding options). Of
these shares, the 2,200,000 shares sold in this offering will be freely tradable
without restriction or further registration under the Securities Act of 1933, as
amended (the "Securities Act"), except that any shares purchased by "affiliates"
of the Company, as that term is defined in Rule 144 ("Rule 144") under the
Securities Act ("Affiliates"), may generally only be sold in compliance with the
limitations of Rule 144 described below.
    
 
SALES OF RESTRICTED SHARES
 
   
     The remaining 10,640,509 shares of Common Stock outstanding upon completion
of this offering will be "restricted securities" as that term is defined in Rule
144 under the Securities Act ("Restricted Shares"). Restricted Shares may be
sold in the public market only if registered or if they qualify for an exemption
from registration under Rule 144 promulgated under the Securities Act, which is
summarized below. Sales of the Restricted Shares in the public market, or the
availability of such shares for sale, could adversely affect the market price of
the Common Stock. Of the Restricted Shares, up to 346,432 may be eligible for
sale in the public market immediately after this offering pursuant to Rule
144(k) under the Securities Act, of which 344,346 shares are subject to lock-up
agreements as described below. An additional 6,833,128 Restricted Shares will be
eligible for resale under Rule 144 commencing 90 days after the effective date
of this offering. All of these shares are subject to lock-up agreements as
described below (the "Lock-Up Agreements"). Approximately 90 days after the date
of this Prospectus, the Company intends to register on one or more registration
statements on Form S-8 approximately 2,972,341 shares of Common Stock issuable
under its restricted stock purchase plan, stock restriction agreements and stock
option plan. Shares covered by such registration statements will be eligible for
sale in the public market after the effective date of such registration, except
for 1,704,146 shares which are subject to the Lock-Up Agreements. In addition,
9,529,862 of the Restricted Shares are entitled to registration rights as
described below.
    
 
   
     In general, under Rule 144 as currently in effect, beginning 90 days after
the effective date of this offering, a person (or persons whose shares are
aggregated) who has beneficially owned Restricted Shares for at least two years
(including the holding period of any prior owner except an affiliate) would be
entitled to sell within any three-month period a number of shares that does not
exceed the greater of (i) one percent of the number of shares of Common Stock
then outstanding (which will equal approximately 128,405 shares immediately
after this offering); or (ii) the average weekly trading volume of the Common
Stock during the four calendar weeks preceding the filing of a Form 144 with
respect to such sale. Sales under Rule 144 are also subject to certain manner of
sale provisions and notice requirements and to the availability of current
public information about the Company. Under Rule 144(k), a person who is not
deemed to have been an affiliate of the Company at any time during the 90 days
preceding a sale, and who has beneficially owned the shares proposed to be sold
for at least three years (including the holding period of any prior owner except
an affiliate), is entitled to sell such shares without complying with the manner
of sale, public information, volume limitation or notice provision of Rule 144.
    
 
     In addition, the Securities and Exchange Commission has proposed an
amendment to Rule 144 which would reduce the holding period by one year before
shares subject to Rules 144 and 144(k) become eligible for sale in the public
market. This proposal, if adopted, would substantially increase the number of
shares of the Company's Common Stock eligible for immediate sale following the
expiration of the lock-up period.
 
OPTIONS
 
     As of September 30, 1996, options to purchase a total of 860,396 shares of
Common Stock were outstanding. Of the total shares issuable pursuant to such
options, 495,757 are subject to lock-up agreements. An additional 763,108 shares
of Common Stock are currently available for future grants
 
                                       49
<PAGE>   54
 
under the Company's stock option and employee stock purchase plans. See
"Management -- Stock Plans."
 
     In general, under Rule 701, as currently in effect, beginning 90 days after
the effective date of this offering, certain shares issued upon exercise of
options granted by the Company prior to the date of this Prospectus will also be
available for sale in the public market. Any employee, officer or director of or
consultant to the Company who purchased his or her shares pursuant to a written
compensatory plan or contract may be entitled to rely on the resale provisions
of Rule 701. Rule 701 permits affiliates to sell their Rule 701 shares under
Rule 144 without complying with the holding period requirements of Rule 144.
Rule 701 further provides that non-affiliates may sell such shares in reliance
on Rule 144 without having to comply with the public information, volume
limitation or notice provisions of Rule 144. In both cases, a holder of Rule 701
shares is required to wait until 90 days after the date of this Prospectus
before selling such shares.
 
     Prior to this offering, there has been no public market for the Common
Stock of the Company and no predictions can be made as to the effect, if any,
that market sales of shares of Common Stock prevailing from time to time may
have on the price of the Common Stock. Nevertheless, sales of significant
numbers of shares of the Common Stock in the public market could adversely
affect the market price of the Common Stock and could impair the Company's
future ability to raise capital through an offering of its equity securities.
 
     The Company intends to file one or more registration statements on Form S-8
under the Securities Act to register all shares of Common Stock subject to
outstanding stock options and Common Stock issuable pursuant to the Company's
restricted stock purchase plan, stock restriction agreements and employee stock
purchase plan that do not qualify for an exemption under Rule 701 from the
registration requirements of the Securities Act. The Company expects to file
these registration statements 90 days after the date of this Prospectus, and
such registration statements are expected to become effective upon filing.
Shares covered by these registration statements will thereupon be eligible for
sale in the public markets, subject to the lock-up agreements, to the extent
applicable.
 
LOCK-UP AGREEMENTS
 
   
     The Company, certain stockholders and all executive officers and directors
of the Company, who in the aggregate hold 10,753,518 shares of Common Stock
(including shares issuable pursuant to the exercise of stock options), have
agreed, pursuant to the lock-up agreements, not to directly or indirectly,
without the prior written consent of Alex. Brown & Sons Incorporated, offer,
sell, offer to sell or otherwise dispose of any shares of Common Stock, options
or warrants to acquire shares of Common Stock, beneficially owned by them for a
period of 180 days after the date of this Prospectus. See "Underwriting."
    
 
REGISTRATION RIGHTS
 
   
     At the completion of this offering, certain stockholders (the
"Rightsholders") will be entitled to require the Company to register under the
Securities Act up to a total 9,529,862 shares of outstanding Common Stock (the
"Registrable Shares") under the terms of agreements among the Company and the
Rightsholders (the "Registration Agreements"). The Registration Agreements
provide that in the event the Company proposes to register any of its securities
under the Securities Act at any time or times, the Rightsholders, subject to
certain exceptions, shall be entitled to include Registrable Shares in such
registration. However, the managing underwriter of any such offering may exclude
for marketing reasons some or all of such Registrable Shares from such
registration. Certain Rightsholders have, subject to certain conditions and
limitations, additional rights to require the Company to prepare and file a
registration statement under the Securities Act with respect to their
Registrable Shares if Rightsholders holding at least a majority of the
Registrable Shares held by all such Rightsholders so request. The Company is
generally required to bear the expenses of all such registrations, except
underwriting discounts and commissions.
    
 
     No predictions can be made as to the effect, if any, that future sales of
shares, or the availability of shares for future sale, will have on the
prevailing market price for the Common Stock. Sales of substantial amounts of
Common Stock, or the perception that such sales could occur, could adversely
affect prevailing market prices for the Common Stock and could impair the
Company's future ability to obtain capital through an offering of equity

     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will purchase all shares of the Common Stock offered hereby if any
of such shares are purchased.
 
     The Company has been advised by the Representatives of the Underwriters
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. The Underwriters may allow, and such dealers may
reallow, a concession not in excess of $          per share to certain other
dealers. After the initial public offering, the public offering price and other
selling terms may be changed by the Representatives of the Underwriters.
 
     The Company and the Selling Stockholders have granted the Underwriters an
option, exercisable not later than 30 days after the date of this Prospectus, to
purchase up to 330,000 additional shares of Common Stock at the initial public
offering price less the underwriting discounts and commissions set forth on the
cover page of this Prospectus. To the extent that the Underwriters exercise such
option, each of the Underwriters will have a firm commitment to purchase
approximately the same percentage thereof that the number of shares of Common
Stock to be purchased by it shown in the above table bears to 330,000, and the
Company and such Selling Stockholders will be obligated, pursuant to cover
over-allotments made in connection with the sale of the Common Stock offered
hereby. If purchased, the Underwriters will offer such additional shares on the
same terms as those on which the 2,200,000 shares of Common Stock are being
offered.
 
     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.
 
   
     The Company and each of its directors and executive officers and certain of
its stockholders, who in the aggregate will hold, following this offering,
10,257,761 shares of Common Stock and options to purchase 495,757 shares of
Common Stock, have agreed that they will not directly or indirectly, without the
prior written consent of Alex. Brown & Sons Incorporated, offer, sell, offer to
sell, contract to sell, or otherwise dispose of any shares of Common Stock for a
period of 180 days after the date of this Prospectus, except that the Company
may issue, and grant options to purchase, shares of Common Stock under its
current stock option and purchase plans and other currently outstanding options.
In addition, the Company may issue shares of Common Stock in connection with
corporate acquisitions so long as such shares are not resold until 180 days
after the date of this Prospectus. See "Shares Eligible for Future Sale."

     The Representatives of the Underwriters have advised the Company that 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 of the
Common Stock will be determined by negotiations among the Company and the
Representatives of the Underwriters. Among the factors to be considered in such
negotiations will be the prevailing market conditions, the results of operations
of the Company in recent periods, the market capitalizations and stages of
development of other companies which the Company and the Representatives of the
Underwriters 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. Application has been made to list the Common
Stock on the Nasdaq National Market under the symbol "GEOC."
 
     The Underwriters have reserved for sale, at the initial public offering
price, up to 7.5% of the shares of Common Stock offered hereby for employees of
the Company and certain other individuals who have expressed an interest in
purchasing such shares of Common Stock in the offering. The number of shares
available for sale to the general public will be reduced to the extent such
persons purchase such reserved shares. Any reserved shares not so purchased will
be offered by the Underwriters to the general public on the same basis as other
shares offered hereby.
 
                                 LEGAL MATTERS
 
   
     The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by Hutchins, Wheeler & Dittmar, A Professional Corporation,
Boston, Massachusetts. Certain legal matters in connection with the offering
will be passed upon for the Underwriters by Hale and Dorr, Boston,
Massachusetts. Anthony J. Medaglia, Jr., a shareholder of Hutchins, Wheeler &
Dittmar, is Secretary of the Company and beneficially owns 39,929 shares of
Convertible Preferred Stock which will convert into 42,095 shares of Common
Stock upon the closing of this offering.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
GeoTel Communications Corporation:
 
     We have audited the accompanying balance sheets of GeoTel Communications
Corporation (formerly a development stage enterprise) as of December 31, 1995
and September 30, 1996, and the related statements of operations, stockholders'
deficit and cash flows for the year ended December 31, 1995 and the nine months
ended September 30, 1996. 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 GeoTel Communications
Corporation as of December 31, 1995 and September 30, 1996, and the results of
its operations and its cash flows for the year ended December 31, 1995 and the
nine months ended September 30, 1996 in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1995 IS UNAUDITED)
 
A. NATURE OF BUSINESS:
 
     GeoTel Communications Corporation (the "Company") develops and markets
telecommunications software solutions, consisting primarily of one product, that
enable enhanced call center applications. The Company engages in a single
business segment.
 
     Principal operations of the Company commenced during 1995. Prior to the
commencement of principal operations, the Company was considered to be a
development stage enterprise. The Company currently derives substantially all of
its revenues from licenses of the Intelligent CallRouter and related services.
 
B. SIGNIFICANT ACCOUNTING POLICIES:
 
  Use of Accounting Estimates
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Interim Financial Statements (unaudited)
 
     The financial statements of the Company for the nine months ended September
30, 1995 and related footnote information are unaudited. All adjustments,
consisting only of normal recurring adjustments, have been made which, in the
opinion of management, are necessary for a fair presentation of the interim
financial information. Results of operations for the nine months ended September
30, 1996 are not necessarily indicative of the results that may be expected for
any future period.
 
  Cash Equivalents and Marketable Securities
 
     The Company considers all highly liquid investments with an original
maturity of 90 days or less to be cash equivalents. The Company classifies its
marketable securities as available-for-sale and states them at amortized cost
plus accrued interest, which approximates fair market value. Marketable
securities include the following at December 31, 1994, December 31, 1995 and
September 30, 1996 (in thousands):

  Income Taxes
 
     The Company provides for income taxes under the liability method, which
requires recognition of deferred tax liabilities and assets for the expected
future tax consequences of events that have been included in the financial
statements or tax returns. Deferred tax liabilities and assets are determined
based on the difference between the financial statement basis of assets and
liabilities
 
                                       F-8

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1995 IS UNAUDITED)
 
using enacted tax rates in effect for the year in which the differences are
expected to reverse. Under this method, a valuation allowance is required
against net deferred tax assets if, based upon the available evidence, it is
more likely than not that some or all of the deferred tax assets will not be
realized.
 
     Management evaluates on a quarterly basis the recoverability of the
deferred tax assets and the level of the valuation allowance. At such time as it
is determined that it is more likely than not that deferred tax assets are
realizable, the valuation allowance will be appropriately reduced.
 
  Property and Equipment
 
     Property and equipment are stated at cost. The Company provides for
depreciation and amortization using the straight-line method over their
estimated useful lives as follows:

    <S>                                                           <C>
    Computer and lab equipment................................             3 years
    Furniture and fixtures....................................             3 years
    Leasehold improvements....................................    Shorter of lease term or
                                                                    estimated useful life
</TABLE>
 
     Repairs and maintenance are charged to expense as incurred. Significant
improvements are capitalized and depreciated. Upon retirement or sale, the cost
of the assets disposed of and the related accumulated depreciation are removed
from the accounts and any resulting gain or loss is included in the results of
operations.
 
  Revenue Recognition
 
     The Company recognizes license fee revenues upon shipment unless there are
significant post-delivery obligations. When significant post-delivery
obligations exist, typically, customer acceptance criteria, revenues are
deferred until no such significant obligations remain. Service and other
revenues have consisted primarily of maintenance, installation and training
revenues. Maintenance revenues are recognized ratably over the term of the
support period, which is typically twelve months. Installation and training
revenues generally are recognized when the services are performed. Amounts
received prior to revenue recognition and for prepaid maintenance revenue are
classified as deferred revenue.
 
  Product Warranty Costs
 
     The Company provides a ninety day warranty and provides for estimated
direct labor and associated indirect costs at the time of sale. Provision for
estimated warranty costs is recorded at the time of sale and periodically
adjusted to reflect actual experience.
 
  Financial Instruments and Concentrations of Credit Risk
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash and cash equivalents,
trade accounts receivable and short-and long-term debt which had fair values
that approximate their carrying amounts. The Company invests its excess cash
primarily in highly rated commercial paper and financial institutions.
 
     Accounts receivable at December 31, 1995 and September 30, 1996 consist
principally of three and eight customer balances, respectively (See Note J). To
reduce risk, the Company routinely assesses the financial strength of its
customers and, as a consequence believes that its trade accounts receivable
credit risk exposure is limited.
 
     Based on borrowing rates currently available to the Company for installment
notes with similar terms and maturities, the fair value of long-term debt
instruments approximates their carrying values.

  Research and Development
 
     Research and development costs are charged to operations as incurred. The
Company capitalizes eligible software costs incurred after technological
feasibility of the product has been established. The Company achieves
technological feasibility when a working model has been established. To date,
costs eligible for capitalization have been immaterial and no costs have been
capitalized.
 
  Net Income (Loss) Per Common and Common Equivalent Share
 
   
     The pro forma net income (loss) per common share is computed based upon the
weighted average number of common and common equivalent shares outstanding
(using the treasury stock method) after certain adjustments described below.
Common equivalent shares consist of the Company's Series A, B and C Convertible
Participating Preferred Stock (collectively, the "Convertible Preferred Stock")
and common stock options outstanding. In accordance with Securities and Exchange
Commission Staff Accounting Bulletin No. 83 (SAB No. 83), all Convertible
Preferred Stock, common and common equivalent shares issued during the twelve
month period prior to the proposed date of the initial filing of the
Registration Statement have been included in the calculation as if they were
outstanding for all periods presented using the treasury stock method at the
assumed initial public offering price. In addition, all outstanding shares of
Convertible Preferred Stock, not subject to SAB No. 83, to be converted into
common stock upon the closing of the initial public offering are treated as
having been converted into common stock at the date of original issuance.
    
 
     Net income (loss) per common share on a historical basis is computed in the
same manner as pro forma net income (loss) per common share, except that all
Convertible Preferred Stock is not assumed to be converted and is included in
the calculation only as a common stock equivalent when its effect is dilutive.

  Pro Forma Presentation (Unaudited)
 
   
     Upon the closing of a public offering, such as the one contemplated in the
Registration Statement in which the accompanying financial statements have been
included, all of the outstanding series of Convertible Preferred Stock will
automatically convert into 8,315,672 shares of common stock (assuming an initial
public offering price of $11.50 per share), and the Company's existing series of
Convertible Preferred Stock will be removed and a class of authorized but
undesignated preferred stock will be created. The unaudited pro forma
presentation of the September 30, 1996 stockholders' equity has been prepared
assuming such conversion.
    
 
  New Accounting Pronouncement
 
     In fiscal year 1996, the Company adopted Statement of Financial Accounting
Standards No. 121 ("SFAS No. 121") "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of," which requires that
impairment losses be recognized when the carrying value of an asset exceeds its
fair value. The Company regularly assesses all of its long-lived assets for
impairment. Based upon Management's assessment as of September 30, 1996, the
Company has determined that no impairment of long-lived assets exists.

inception (June 4, 1993) through December 31, 1993 and for the years ended
December 31, 1994 and 1995, and for the nine months ended September 30, 1996 as
the Company has not reported taxable income in those periods. The Company
elected to capitalize start-up costs and research and development costs for
income tax purposes and amortize them over five and ten years, respectively, for
the period prior to recording product revenue in 1995.

</TABLE>
 
     Valuation allowances have been recorded to offset the entire net deferred
tax assets as a result of the uncertainties regarding the realization of the
asset due to the limited history of operating profits.
 
     The difference between the statutory federal income tax rate and the
Company's effective tax rate for the nine months ended September 30, 1996 is
principally due to the utilization of net operating losses, capitalized start-up
costs including capitalized research and development cost carryforwards.
 
     At September 30, 1996, the Company had net operating loss carryforwards of
$1,400,000 for federal and state income tax purposes, and capitalized start-up
costs of approximately $4,800,000 that may be used to offset future federal
income tax, if any. The net operating loss carryforwards expire at various dates
beginning in 2009. Similarly, research and development and state investment tax
credit carryforwards aggregating $245,000 and $183,000 were available at
December 31, 1995 and September 30, 1996, respectively, which expire at various
dates beginning in 2009. An ownership change, as defined in the Tax Reform Act
of 1986, may restrict the utilization of certain tax attributes. The difference
between the federal net operating loss carryforwards and the amount of the
accumulated deficit results primarily from certain start-up costs and research
and development expenses, which have been capitalized for tax purposes.
 
E. LONG-TERM DEBT:
 
     In 1994, the Company entered into an equipment line of credit agreement
with a bank. The agreement allowed the Company to borrow the lesser of $500,000
or a 90% advance rate against the invoice price of approved equipment purchased
after January 1, 1994, as defined. The agreement provided for two borrowing
periods. The first borrowing period began on May 18, 1994 and ended on November
5, 1994. The Company borrowed a total of approximately $319,000 under the line
of credit in the first borrowing period. This outstanding principal balance is
payable monthly, in 30 equal payments of principal plus interest, commencing on
December 5, 1994. The second borrowing period began on November 6, 1994 and
ended on May 5, 1995. The Company borrowed a total of approximately $148,000
under the line of credit in the second borrowing period. This outstanding
principal balance is payable monthly, in 30 equal payments of principal plus
interest, which began on June 5, 1995.
 
     In 1995, the Company entered into a second equipment line of credit
agreement with the bank. The agreement allows the Company to borrow the lesser
of $600,000 or a 90% advance rate against the invoice price of approved
equipment purchased after November 30, 1994, as defined. The

agreement provided for two borrowing periods. The first borrowing period began
on May 1, 1995 and ended on March 1, 1996. The Company borrowed a total of
approximately $385,000 under the line of credit in the first borrowing period.
This outstanding principal balance is payable monthly, in 36 equal payments of
principal plus interest, commencing on April 1, 1996. The second borrowing
period began on April 2, 1996 and ended on May 31, 1996. The Company borrowed a
total of approximately $214,000 under the line of credit in the second borrowing
period. This outstanding principal balance is payable monthly, in 34 equal
payments of principal plus interest, which began on June 1, 1996.
 
     In September 1996, the Company entered into a third equipment line of
credit agreement with the bank. The agreement allows the Company to borrow the
lesser of $800,000 or a 90% advance rate against the invoice price of approved
equipment purchased after May 31, 1996, as defined. Borrowings outstanding under
this agreement approximated $143,000 at September 30, 1996. The borrowing period
ends on June 30, 1997.
 
     Borrowings under the above agreements bear interest ranging from the bank's
prime rate to prime rate plus 1% (9.50% at December 31, 1995 and 8.25% at
September 30, 1996). The interest rate, on all outstanding debt, was reduced to
prime rate in September 1996.
 
     The borrowings are collateralized by substantially all of the Company's
assets. These agreements contain restrictive covenants that require certain
levels of equity and liquidity and prohibit the payment of cash dividends
without the bank's consent. At December 31, 1995 and September 30, 1996, the
Company was in compliance with all related covenants.
 
     Principal payments for the last three months of 1996 and for the years
1997, 1998, 1999 and 2000 are $101,000, $347,000, $252,000, $99,000 and $24,000,
respectively.

dividends will be determined by the number of shares of common stock into which
each share of preferred stock could then be converted, as defined. The Company
is prohibited from paying cash dividends under the outstanding equipment lines
unless the Company receives the bank's consent.
 
  Liquidation
 
     In certain events, including liquidation, dissolution or the winding up of
the Company, the holders of the Series A, B and C Convertible Preferred Stock
are entitled to receive an amount equal to $1.00, $1.75 and $2.336 per share,
respectively, plus declared but unpaid dividends, before any payment is made to
the common stockholders. The holders of the Convertible Preferred Stock shall
then share ratably with the common stockholders in the distribution of the
remaining assets distributable to the stockholders as if each share of
Convertible Preferred Stock had been converted, as defined.
 
  Voting
 
     Preferred stockholders are entitled to the number of votes equal to the
number of shares of common stock into which each share of Convertible Preferred
Stock is convertible.
 
  Conversion and Redemption
 
   
     The holders of a majority of the outstanding shares of Convertible
Preferred Stock shall be entitled, at any time after July 31, 2000, to cause all
such shares to be converted into common stock on a share-for-share basis, as
defined and to receive from the Company their liquidation amount in three equal,
annual installments. In addition, immediately prior to the closing of an initial
public offering of the Company's common stock, which results in proceeds of at
least $10,000,000 and a per share price of a least $4.67, each share of the
Convertible Preferred Stock will automatically convert. In September 1996, the
Company's Board of Directors adopted and the stockholders approved an amendment
to the terms of the Company's Convertible Preferred Stock to provide that, in
lieu of any cash payment in connection with the automatic conversion of the
Convertible Preferred Stock in an initial public offering, the Convertible
Preferred Stock will be converted into an additional number of shares of common
stock determined by dividing fifty percent of the original purchase price of the
Convertible Preferred Stock by the initial public offering price. At an assumed
initial public offering price of $11.50 per share, the Convertible Preferred
Stock will be converted into an additional 527,057 shares of Common Stock. Since
the holders of the Convertible Preferred Stock have voting control, such
conversion will result in an increase in common stock and additional paid-in
capital with no impact on net income or earnings per share.
    
 
     The Convertible Preferred Stock is being accreted to approximately
$12,756,000 which is equal to the sum of (i) the price per share paid for each
share of Convertible Preferred Stock and (ii) the fair value of the common
stock, at the date of the original issuance of the Convertible Preferred Stock,
for which such Convertible Preferred Stock will be converted. The Company has
provided for periodic accretion of the fair value of the common stock using the
effective interest method.

G. STOCKHOLDERS' EQUITY (DEFICIT):
 
  Common and Preferred Stock
 
     In September 1996, the Company's Board of Directors authorized management
of the Company to file a Registration Statement with the Securities and Exchange
Commission permitting the Company to sell shares of common stock to the public.
In addition, the Company's Board of Directors adopted and the stockholders
approved an increase in the number of authorized shares of capital stock from
21,788,615 shares to 45,000,000 shares, to be effected upon the closing of the
offering, of which 40,000,000 shares have been designated as common stock and
5,000,000 shares have been designated as preferred stock, for which the
Company's Board of Directors will have the authority, without further
stockholder approval, to issue in one or more series and to fix the relative
rights, preferences, privileges, qualifications, limitations 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 any series or the designation of such series.
 
     Each share of common stock has full voting rights. The terms of the
Company's existing borrowing arrangements with a bank prohibit the payment of
cash dividends without the prior consent of the bank.
 
  Stock Restriction Agreements
 
     The Company has entered into Stock Restriction Agreements (the "Stock
Restriction Agreements") with certain employees pursuant to which such employees
purchased an aggregate of 1,444,278 shares of common stock, of which 1,034,028
were purchased for $0.01 per share in 1993 and 410,250 were purchased for $0.10
per share in 1994. In connection with the 1994 sale of common stock described
above, the Company received a full recourse note receivable totaling
approximately $37,000 from a certain employee. This note bears interest at 5.25%
and is required to be paid in full upon the earlier to occur of the tenth
anniversary date of issuance or the first anniversary of an initial public
offering or other liquidity event, as defined. All shares purchased under the
Stock Restriction Agreements are subject to repurchase by the Company at the
original purchase price for up to a period of five years from the date of
purchase, unless the shares become vested. An employee vests in twenty percent
of the shares on the first anniversary of the date of purchase and, thereafter,
the remaining shares become vested on a monthly basis through the fifth
anniversary of the date of purchase. In accordance with the terms of a Stock
Restriction Agreement, the Company repurchased 148,211 unvested shares in 1994
at a price of $0.01 per share from an employee whose employment with the Company
terminated. In addition, the Company repurchased 58,595 shares from this
employee in 1995 at a price of $0.30 per share. At September 30, 1996, 448,233
shares were subject to repurchase under the Stock Restriction Agreements. Upon
an initial public offering, all shares of common stock purchased under the Stock
Restriction Agreements will become vested.
 
     The Stock Restriction Agreements further provide the Company and the
holders of the Convertible Preferred Stock with the right of first refusal to
purchase the shares of such an employee stockholder if he intends to sell them
and has received an offer from a third party. The Company may exercise its right
to purchase the shares at the offeror's price within 30 days of receipt of
written notification of the stockholder's intent to sell. If the Company elects
not to purchase the stock, the preferred stockholders may exercise their right
to purchase their pro rata share at the offeror's price for a period of 20 days.
If the preferred stockholders do not purchase the shares, then the stockholder
is free to transfer the shares to the offeror, provided the transfer is
completed within

three months from the end of the preferred stockholder option period. These
Stock Restriction Agreements terminate upon an initial public offering.
 
  Restricted Stock Purchase Plan
 
     The Company has adopted, and subsequently amended, a 1993 Restricted Stock
Purchase Plan (the "1993 Plan"), which provides for the issuance of common stock
to directors, officers, consultants and other key personnel at prices determined
by a Committee selected by the Board of Directors. Participants' shares are
subject to repurchase by the Company at the original purchase price for up to
five years after the beginning of the vesting period. A participant vests in
twenty percent of the shares on the first anniversary of the date of purchase
and, thereafter, the remaining shares become vested on a monthly basis through
the fifth anniversary date of purchase. At December 31, 1995 and September 30,
1996, the Company may repurchase up to 868,222 and 533,925 unvested shares,
respectively. Such shares are to be repurchased at the original purchase price
ranging from $0.10 to $0.18 per share. There are no shares available for further
grant under the 1993 Plan. The shares outstanding at September 30, 1996 under
the 1993 Plan have a weighted price of $0.14 per share with share prices ranging
from $0.10 to $0.18 per share.
 
     Information related to the 1993 Plan is as follows:

     In connection with the sale of common stock under the 1993 Plan described
above, the Company received full recourse notes receivable totaling
approximately $57,000 and $86,000 from certain employees during the years ended
December 31, 1994 and 1995, respectively. These notes bear interest at 5.25% and
are required to be paid in full upon the earlier to occur of the tenth
anniversary of the date of issuance or the first anniversary of an initial
public offering or other liquidity event, as defined. The interest is payable at
the date of maturity. Such notes are collateralized by the common stock
purchased and accordingly are included in stockholders' deficit.
 
  Stock Option Plan
 
     In 1995, the Board of Directors adopted and the stockholders subsequently
approved the Company's 1995 stock option plan (the "1995 Plan"), which provides
for the issuance of incentive stock options and nonqualified stock options to
eligible employees, officers and consultants to the Company. The options can be
granted for periods of up to ten years and generally vest ratably over a
five-year period with initial vesting occurring on the first anniversary from
the grant date and then monthly thereafter. In 1996, the Board of Directors
adopted and stockholders approved an increase in the 1995 Plan of 1,000,000
shares of common stock. In addition, the Board of Directors adopted and
stockholders approved the number of shares of common stock available for grants
under the 1995 Plan to be increased by the number of shares repurchased by the
Company from time to time under the 1993 Plan. The maximum number of shares will
increase effective January 1, 1997 and

each January 1 thereafter during the term of the 1995 Plan, by an amount equal
to four percent of the total number of shares of common stock issued and
outstanding as of the close of business on December 31, of the preceding year,
not exceeding 6,000,000 shares. At December 31, 1995 and September 30, 1996,
426,051 and 1,474,726 shares, respectively, were authorized for issuance under
the 1995 Plan.
 
     The option price for stock options granted under the 1995 Plan is
determined by a Committee consisting of two or more members of the Company's
Board of Directors. The option price for incentive stock options shall be the
fair value at the time the option is granted. In the case of options granted to
a shareholder who at the time of grant owns, directly or indirectly, stock
possessing more than 10% of total combined voting power of any class of stock of
the Company, the exercise price of the options shall not be less than 110% of
the fair value of the common stock as of the date of grant.

     The Company granted options at the per share price, which have ranged from
$0.18 to $8.00 per share, generally equal to the fair value on the date of each
grant. No options were exercisable as of December 31, 1995 and 8,400 were
exercisable at September 30, 1996. The 101,222 options exercised during the nine
months ended September 30, 1996, related to merit grants which included
immediate vesting provisions. As of December 31, 1995 and September 30, 1996,
the Company had 361,551 and 513,108, respectively, shares available for future
option grants under the 1995 Plan. The outstanding stock options at September
30, 1996 have a weighted average contractual life of 9.67 years.
 
  Employee Stock Purchase Plan
 
     In September 1996, the Company's Board of Directors adopted and the
stockholders approved the 1996 Employee Stock Purchase Plan (the "1996 Purchase
Plan"). The Company has reserved 250,000 shares of common stock for issuance
under the 1996 Purchase Plan. The 1996 Purchase Plan will enable employees to
purchase common stock at 85% of the lower of the fair market value of the
Company's common stock on the first or last day of each six-month purchase
period.
 
  Stock-Based Compensation Plans
 
   
     The Company applies Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees, and related interpretations in accounting for the
1995 Plan. Accordingly, compensation expense has been recognized for its
stock-based compensation plan for any options granted below fair value of the
common stock. In the nine months ended September 30, 1996, the Company
recognized approximately $1,147,000 in unearned compensation for options to
purchase 696,180 shares granted at exercise prices below the fair value of the
common stock. Had compensa-

tion cost for the 1995 Plan been determined based upon the fair value at the
grant date for awards consistent with the minimum value methodology prescribed
under Statement of Financial Accounting Standards No. 123 ("SFAS 123")
"Accounting for Stock-Based Compensation," the Company's net loss would have
increased by approximately $9,000 in 1995 and net income would have decreased by
approximately $32,000 for the nine months ended September 30, 1996. The pro
forma effect of adopting SFAS 123 has no effect on the Company's net income
(loss) per share in 1995 and a decrease to $0.02 per share for the nine months
ended September 30, 1996. In computing these pro forma amounts the Company has
assumed a risk-free interest rate equal to approximately 8% and expected life of
approximately five years. The options granted during 1995 and for the nine
months ended September 30, 1996 are generally equal to the fair value at the
time of option grant. The effects of applying SFAS 123 in this disclosure are
not indicative of future amounts. SFAS 123 does not apply to awards prior to
1995, and additional awards in future years are anticipated.
    
 
H. RETIREMENT SAVINGS PLAN:
 
     In 1994, the Company adopted a Retirement Savings Plan (the "Savings Plan")
for its employees, which has been qualified under Section 401(k) of the Internal
Revenue Code. Eligible employees are permitted to contribute to the Savings Plan
through payroll deductions within statutory limitations and subject to any
limitations included in the Savings Plan. To date the Company has made no
contributions to the Plan.
 
I. OPERATING LEASES:
 
     The Company leases certain equipment and office space under operating
leases that expire through 1998. Future minimum annual lease commitments,
including operating costs, under the operating leases for the last three months
of 1996, and for the years 1997 and 1998 are $38,000, $158,000 and $145,000,
respectively.
 
     Rent expense was approximately $1,000, $41,000, $124,000, $89,000 and
$135,000 from inception (June 4, 1993) through December 31, 1993 and the years
ended December 31, 1994 and 1995 and for the nine month periods ended September
30, 1995 and 1996, respectively.
 
J. RELATED PARTY TRANSACTIONS AND SIGNIFICANT CUSTOMERS:
 
     In August 1995, the Company sold 1,048,801 shares of Series C Convertible
Participating Preferred Stock to an investor that subsequently became a customer
of the Company. This customer's purchases from the Company represented 38% and
20% of revenue for the year ended December 31, 1995 and the nine months ended
September 30, 1996, respectively, and this customer had an outstanding
receivable balance of approximately $266,000 and $751,000 at December 31, 1995
and September 30, 1996, respectively. Gross profit from related party
transactions approximated those realized in similar transactions with unrelated
parties. Purchases by this customer for the year ended December 31, 1995 were
made through another shareholder of the Company.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the underwriting agreements 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
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the Restated Certificate of Incorporation and Amended and
Restated Bylaws of the Registrant and the laws of the State of Delaware, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being
 
                                      II-3
<PAGE>   82
 
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 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
     of 1933, 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 of 1933, 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.

                                                               November   , 1996
 
Alex. Brown & Sons Incorporated
Wessels, Arnold & Henderson, L.L.C.
As Representatives of the
  Several Underwriters
c/o Alex. Brown & Sons Incorporated
135 East Baltimore Street
Baltimore, Maryland 21202
 
Gentlemen:
 
     GeoTel Communications Corporation, a Delaware corporation (the "Company"),
proposes to sell to the several underwriters (the "Underwriters") named in
Schedule I hereto for whom you are acting as representatives (the
"Representatives") an aggregate of 2,200,000 shares of the Company's Common
Stock, $.01 par value (the "Firm Shares"). The respective amounts of the Firm
Shares to be so purchased by the several Underwriters are set forth opposite
their names in Schedule I hereto. The Company and certain shareholders of the
Company (the "Selling Shareholders") also propose to sell at the Underwriters'
option an aggregate of up to 330,000 additional shares of the Company's Common
Stock (the "Option Shares") as set forth below. The maximum number of Option
Shares to be sold by the Company and the Selling Shareholders are set forth
opposite their names on Schedule II hereto. The Company and the Selling
Shareholders are sometimes referred to herein collectively as the "Sellers."
 
     As the Representatives, you have advised the Company and the Selling
Shareholders (a) that you are authorized to enter into this Agreement on behalf
of the several Underwriters, and (b) that the several Underwriters are willing,
acting severally and not jointly, to purchase the numbers of Firm Shares set
forth opposite their respective names in Schedule I, plus their pro rata portion
of the Option Shares if you elect to exercise the over-allotment option in whole
or in part for the accounts of the several Underwriters. The Firm Shares and the
Option Shares (to the extent the aforementioned option is exercised) are herein
collectively called the "Shares."
 
     In consideration of the mutual agreements contained herein and of the
interests of the parties in the transactions contemplated hereby, the parties
hereto agree as follows:
 
     1.  Representations and Warranties of the Company and the Selling
         Shareholders.
 
          (a) The Company represents and warrants as follows:
 
             (i) A registration statement on Form S-1 (File No. 333-13263) with
        respect to the Shares has been carefully prepared by the Company in
        conformity with the requirements of the Securities Act of 1933, as
        amended (the "Act"), and the Rules and Regulations (the "Rules and
        Regulations") of the Securities and Exchange Commission (the
        "Commission") thereunder and has been filed with the Commission. Copies
        of such registration statement, including any amendments thereto, the
        preliminary prospectuses (meeting the requirements of the Rules and
        Regulations) contained therein and the exhibits, financial
<PAGE>   2
 
        statements and schedules, as finally amended and revised, have
        heretofore been delivered by the Company to you. Such registration
        statement, together with any registration statement filed by the Company
        pursuant to Rule 462(b) of the Act, herein referred to as the
        "Registration Statement," which shall be deemed to include all
        information omitted therefrom in reliance upon Rule 430A and contained
        in the Prospectus referred to below, has been declared effective by the
        Commission under the Act and no post-effective amendment to the
        Registration Statement has been filed as of the date of this Agreement.
        For purposes of this Agreement, the term "Prospectus" means (a) the form
        of prospectus first filed with the Commission pursuant to Rule 424(b) or
        (b) the last preliminary prospectus included in the Registration
        Statement filed prior to the time it becomes effective or filed pursuant
        to Rule 424(a) under the Act that is delivered by the Company to the
        Underwriters for delivery to purchasers of the Shares, together with the
        term sheet or abbreviated term sheet filed with the Commission pursuant
        to Rule 424(b)(7) under the Act. Each preliminary prospectus included in
        the Registration Statement prior to the time it becomes effective is
        herein referred to as a "Preliminary Prospectus."
 
             (ii) The Company has been duly organized and is validly existing as
        a corporation in good standing under the laws of the State of Delaware,
        with corporate power and authority to own or lease its properties and
        conduct its business as described in the Registration Statement. The
        Company is duly qualified to transact business in all jurisdictions in
        which the conduct of its business requires such qualification, except
        where the failure so to qualify would not have a material adverse effect
        on the earnings, business, management, properties, assets, operations or
        condition (financial or otherwise) of the Company. There is no
        corporation, partnership, joint venture or other entity in which the
        Company has, directly or indirectly, any equity interest.
 
             (iii) The outstanding shares of Common Stock of the Company,
        including all shares to be sold by the Selling Shareholders, have been
        duly authorized and validly issued and are fully paid and
        non-assessable; the portion of the Shares to be issued and sold by the
        Company have been duly authorized and when issued and paid for as
        contemplated herein will be validly issued, fully paid and
        non-assessable; and no preemptive rights of shareholders exist with
        respect to any of the Shares or the issue and sale thereof. Neither the
        filing of the Registration Statement nor the offering or sale of the
        Shares as contemplated by this Agreement gives rise to any rights, other
        than those which have been waived or satisfied, for or relating to the
        registration of any shares of Common Stock.
 
             (iv) The information set forth under the caption "Capitalization"
        in the Prospectus is true and correct as of the dates indicated in the
        information included under such caption. All of the Shares conform to
        the description thereof contained in the Registration Statement. The
        form of certificates for the Shares conforms to the corporate law of the
        jurisdiction of the Company's incorporation.
 
             (v) The Commission has not issued an order preventing or suspending
        the use of any Prospectus relating to the proposed offering of the
        Shares nor instituted proceedings for that purpose. The Registration
        Statement contains, and the Prospectus and any amendments or supplements
        thereto will contain, all statements which are required to be stated
        therein by, and in all respects conform or will conform, as the case may
        be, to the requirements of, the Act and the Rules and Regulations. The
        Registration Statement and any amendment thereto do not contain, and
        will not contain, any untrue statement of a material fact and do not
        omit, and will not omit, to state any material fact required to be
        stated therein or necessary to make the statements therein, in light of
        the circumstances under which they were made, not misleading. The
        Prospectus and any amendments and supplements thereto do not contain,
        and will not contain, any untrue statement of material fact and do not
        omit, and will not omit, to state any 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,
 
                                        2
<PAGE>   3
 
        not misleading; provided, however, that the Company makes no
        representations or warranties as to information contained in or omitted
        from the Registration Statement or the Prospectus, or any such amendment
        or supplement, in reliance upon, and in conformity with, written
        information furnished to the Company by or on behalf of any Underwriter
        through the Representatives specifically for use in the preparation
        thereof.
 
             (vi) The financial statements of the Company, together with related
        notes as set forth in the Registration Statement, present fairly the
        financial position and the results of operations and cash flows of the
        Company at the indicated dates and for the indicated periods. Such
        financial statements have been prepared in accordance with generally
        accepted accounting principles, consistently applied throughout the
        periods involved, and all adjustments necessary for a fair presentation
        of results for such periods have been made. The summary financial and
        statistical data included in the Registration Statement presents fairly
        the information shown therein and such data has been compiled on a basis
        consistent with the financial statements presented therein and the books
        and records of the Company.
 
             (vii) Each of Coopers & Lybrand L.L.C. and Arthur Andersen LLP, who
        have certified certain of the financial statements filed with the
        Commission as part of the Registration Statement, are independent public
        accountants as required by the Act and the Rules and Regulations.
 
             (viii) There is no action, suit, claim or proceeding pending or, to
        the knowledge of the Company, threatened against the Company before any
        court or administrative agency or otherwise which if determined
        adversely to the Company might result in any material adverse change in
        the earnings, business, management, properties, assets, operations or
        condition (financial or otherwise) of the Company or prevent the
        consummation of the transactions contemplated hereby, except as set
        forth in the Registration Statement.
 
             (ix) The Company has good and marketable title to all of the
        properties and assets reflected in the financial statements (or as
        described in the Registration Statement) hereinabove described, subject
        to no lien, mortgage, pledge, charge or encumbrance of any kind except
        those reflected in such financial statements (or as described in the
        Registration Statement) or which are not material in amount. The Company
        occupies its leased properties under valid and binding leases conforming
        to the description thereof set forth in the Registration Statement.
 
             (x) The Company has filed all federal, state, local and foreign
        income tax returns which has been required to be filed and has paid all
        taxes indicated by said returns and all assessments received by it to
        the extent that such taxes have become due, except for amounts which are
        not material to the financial condition of the Company. All tax
        liabilities have been adequately provided for in the financial
        statements of the Company, except for amounts which are not material to
        the financial condition of the Company.
 
             (xi) Since the respective dates as of which information is given in
        the Registration Statement, as it may be amended or supplemented, there
        has not been any material adverse change or any development involving a
        prospective material adverse change in or affecting the earnings,
        business, management, properties, assets, operations or condition
        (financial or otherwise) of the Company, whether or not occurring in the
        ordinary course of business, and there has not been any material
        transaction entered into by the Company or any material transaction that
        is probable of being entered into by the Company, other than
        transactions in the ordinary course of business and changes and
        transactions described in the Registration Statement, as it may be
        amended or supplemented. The Company does not have any material
        contingent obligations which are not disclosed in the Company's
        financial statements which are included in the Registration Statement.
 
                                        3

             (xii) The Company is not and with the giving of notice or lapse of
        time, or both, will not be in violation of or in default under its
        Certificate of Incorporation or By-laws or under any agreement, lease,
        contract, indenture or other instrument or obligation to which it is a
        party or by which it or any of its properties is bound and which default
        is of material significance in respect of the business, management,
        properties, assets, operations or condition (financial or otherwise) of
        the Company. The execution and delivery of this Agreement and the
        consummation of the transactions herein contemplated and the fulfillment
        of the terms hereof will not conflict with or result in a breach of any
        of the terms or provisions of, or constitute a default under, any
        indenture, mortgage, deed of trust or other agreement or instrument to
        which the Company is a party, or of the Certificate of Incorporation or
        By-laws of the Company or any order, rule or regulation applicable to
        the Company of any court or of any regulatory body or administrative
        agency or other governmental body having jurisdiction.
 
             (xiii) Each approval, consent, order, authorization, designation,
        declaration or filing by or with any regulatory, administrative or other
        governmental body necessary in connection with the execution and
        delivery by the Company of this Agreement and the consummation of the
        transactions herein contemplated (except such additional steps as may be
        required by the National Association of Securities Dealers, Inc. (the
        "NASD") or such additional steps as may be necessary to qualify the
        Shares for public offering by the Underwriters under state securities or
        Blue Sky laws) has been obtained or made and is in full force and
        effect.
 
             (xiv) The Company holds all material licenses, certificates and
        permits from governmental authorities which are necessary to the conduct
        of its business; and, to the Company's knowledge, the Company has not
        infringed any patents, patent rights, trade names, trademarks or
        copyrights, which infringement is material to the business of the
        Company.
 
             (xv) Neither the Company, nor to the Company's knowledge, any of
        its affiliates, has taken or may take, directly or indirectly, any
        action designed to cause or result in, or which has constituted or which
        might reasonably be expected to constitute, the stabilization or
        manipulation of the price of the shares of Common Stock to facilitate
        the sale or resale of the Shares.
 
             (xvi) The Company is not, and after giving effect to the issuance
        of the Shares hereunder will not be, an "investment company" within the
        meaning of such term under the Investment Company Act of 1940, as
        amended (the "1940 Act"), and the rules and regulations of the
        Commission thereunder.
 
             (xvii) The Company maintains a system of internal accounting
        controls sufficient to provide reasonable assurances that (A)
        transactions are executed in accordance with management's general or
        specific authorization; (B) transactions are recorded as necessary to
        permit preparation of financial statements in conformity with generally
        accepted accounting principles and to maintain accountability for
        assets; (C) access to assets is permitted only in accordance with
        management's general or specific authorization; and (D) the recorded
        accountability for assets is compared with existing assets at reasonable
        intervals and appropriate action is taken with respect to any
        differences.
 
             (xviii) The Company carries, or is covered by, insurance in such
        amounts and covering such risks as is adequate for the conduct of its
        business and the value of its properties and as is customary for
        companies engaged in similar industries.
 
             (xix) The Company confirms as of the date hereof that it is in
        compliance with all provisions of Section 1 of Laws of Florida, Chapter
        92-198, An Act Relating to Disclosure of doing Business with Cuba, and
        the Company further agrees that if it commences engaging in business
        with the government of Cuba or with any person or affiliate located in
        Cuba after
 
                                        4
<PAGE>   5
 
        the date the Registration Statement becomes or has become effective with
        the Commission or with the Florida Department of Banking and Finance
        (the "Department"), whichever date is later, or if the information
        reported or incorporated by reference in the Prospectus, if any,
        concerning the Company's business with Cuba or with any person or
        affiliate located in Cuba changes in any material way, the Company will
        provide the Department notice of such business or change, as
        appropriate, in a form acceptable to the Department.
 
             (xx) The Company owns or possesses adequate licenses or other
        rights to use all patents, patent applications, trademarks, trademark
        applications, service marks, service mark applications, trade names,
        copyrights, trade secrets and know-how or other information
        (collectively "Intellectual Property") described in the Prospectus as
        owned or used by it or which is necessary for the conduct of its
        business as now conducted or proposed to be conducted as described in
        the Prospectus. To the Company's knowledge, none of the Company's
        products, services or Intellectual Property infringes or conflicts with
        the rights or claims of others. The Company is not aware of any
        infringement of any of the Company's Intellectual Property rights by any
        third party which could have a material adverse effect on the earnings,
        business, management, properties, assets, operations or condition
        (financial or otherwise) of the Company.
 
             (xxi) Except as otherwise set forth in the Prospectus, there are no
        material legal, governmental, regulatory or administrative proceedings
        pending to which the Company is a party or to which any of its property
        is subject and, to the Company's knowledge, no such proceedings are
        threatened or contemplated.
 
             (xxii) No contract or document of a character required to be
        described in the Registration Statement or the Prospectus or to be filed
        as an exhibit to the Registration Statement is not so described or filed
        as required.
 
          (b) Each of the Selling Shareholders severally represents and warrants
     as follows:
 
             (i) Such Selling Shareholder now has and at any Option Closing Date
        (as such date is hereinafter defined) will have good and marketable
        title to any Option Shares to be sold by such Selling Shareholder, free
        and clear of any liens, encumbrances, equities and claims, and full
        right, power and authority to effect the sale and delivery of such
        Option Shares; and upon the delivery of and payment for such Option
        Shares pursuant to this Agreement, the Underwriters will acquire good
        and marketable title thereto, free and clear of any liens, encumbrances,
        equities and claims.
 
             (ii) Such Selling Shareholder has full right, power and authority
        to execute and deliver this Agreement and the Power of Attorney and
        Custodian Agreement referred to below and to perform such Selling
        Shareholder's obligations under such documents. The execution and
        delivery of this Agreement, the Power of Attorney and the Custodian
        Agreement, the consummation by such Selling Shareholder of the
        transactions herein and therein contemplated and the fulfillment by such
        Selling Shareholder of the terms hereof and thereof will not require any
        consent, approval, authorization or order of or declaration or filing
        with any court, regulatory body, administrative agency or other
        governmental body (except as may be required under the Act, state
        securities laws or Blue Sky laws) and will not result in a breach of any
        of the terms and provisions of, or constitute a default under,
        organizational documents of such Selling Shareholder, if not an
        individual, or any indenture, mortgage, deed of trust or other agreement
        or instrument to which such Selling Shareholder is a party, or of any
        order, rule or regulation applicable to such Selling Shareholder of any
        court or of any regulatory body or administrative agency or other
        governmental body having jurisdiction.
 
             (iii) Such Selling Shareholder has not taken and will not take,
        directly or indirectly, any action designed to, or which has
        constituted, or which might reasonably be expected to
 
                                        5
<PAGE>   6
 
        cause or result in the stabilization or manipulation of the price of the
        Common Stock of the Company and, other than as permitted by the Act, the
        Selling Shareholder will not distribute any prospectus or other offering
        material in connection with the offering of the Shares.
 
             (iv) Without having undertaken to determine independently the
        accuracy or completeness of either the representations and warranties of
        the Company contained herein or the information contained in the
        Registration Statement, such Selling Shareholder has no reason to
        believe that the representations and warranties of the Company contained
        in this Section 1 are not true and correct, is familiar with the
        Registration Statement and has no knowledge of any material fact,
        condition or information not disclosed in the Registration Statement
        which has adversely affected or may reasonably be expected to adversely
        affect the business of the Company; and the sale of any Option Shares by
        such Selling Shareholder pursuant hereto is not prompted by any
        information concerning the Company which is not set forth in the
        Registration Statement. The information pertaining to such Selling
        Shareholder under the caption "Principal and Selling Stockholders" in
        the Prospectus is complete and accurate in all material respects.
 
     2.  Purchase, Sale and Delivery of the Shares.
 
          (a) On the basis of the representations, warranties and covenants
     herein contained, and subject to the conditions herein set forth, the
     Company agrees to sell to the Underwriters and each Underwriter agrees,
     severally and not jointly, to purchase, at a price of $ per share, the
     number of Firm Shares set forth opposite the name of each Underwriter in
     Schedule I hereof, subject to adjustment in accordance with Section 9
     hereof.
 
          (b) Payment for the Firm Shares to be sold hereunder is to be made in
     same day funds by wire transfer or certified or bank cashier's checks drawn
     to the order of the Company against delivery of certificates therefor to
     the Representatives for the several accounts of the Underwriters. Such
     payment and delivery are to be made at the offices of Alex. Brown & Sons
     Incorporated, 135 East Baltimore Street, Baltimore, Maryland, at 10:00
     a.m., Baltimore time, on the third business day after the date of this
     Agreement or at such other time and date not later than five business days
     thereafter as you and the Company shall agree upon, such time and date
     being herein referred to as the "Closing Date." (As used herein, "business
     day" means a day on which the New York Stock Exchange is open for trading
     and on which banks in New York are open for business and not permitted by
     law or executive order to be closed.) The certificates for the Firm Shares
     will be delivered in such denominations and in such registrations as the
     Representatives request in writing not later than the second full business
     day prior to the Closing Date, and will be made available for inspection by
     the Representatives at least one business day prior to the Closing Date.
 
          (c) In addition, on the basis of the representations and warranties
     herein contained and subject to the terms and conditions herein set forth,
     the Company and the Selling Shareholders listed on Schedule II hereto
     hereby grant an option to the several Underwriters to purchase the Option
     Shares at the price per share as set forth in the first paragraph of this
     Section 2. The maximum number of Option Shares to be sold by the Company
     and such Selling Shareholders is set forth opposite their respective names
     on Schedule II hereto. The option granted hereby may be exercised in whole
     or in part by giving written notice (i) at any time before the Closing Date
     and (ii) only once thereafter within 30 days after the date of this
     Agreement, by you, as Representatives of the several Underwriters, to the
     Company and the Custodian setting forth the number of Option Shares as to
     which the several Underwriters are exercising the option, the names and
     denominations in which the Option Shares are to be registered and the time
     and date at which such certificates are to be delivered. If the option
     granted hereby is exercised in part, the respective number of Option Shares
     to be sold by the Company and each of the Selling Shareholders listed in
     Schedule II hereto shall be determined on a pro rata basis in accordance
 
                                        6
<PAGE>   7
 
     with the percentages set forth opposite their names on Schedule II hereto,
     adjusted by you in such manner as to avoid fractional shares. The time and
     date at which certificates for Option Shares are to be delivered shall be
     determined by the Representatives but shall not be earlier than three nor
     later than 10 full business days after the exercise of such option, nor in
     any event prior to the Closing Date (such time and date being herein
     referred to as the "Option Closing Date"). If the date of exercise of the
     option is three or more days before the Closing Date, the notice of
     exercise shall set the Closing Date as the Option Closing Date. The number
     of Option Shares to be purchased by each Underwriter shall be in the same
     proportion to the total number of Option Shares being purchased as the
     number of Firm Shares being purchased by such Underwriter bears to the
     total number of Firm Shares, adjusted by you in such manner as to avoid
     fractional shares. The option with respect to the Option Shares granted
     hereunder may be exercised only to cover over-allotments in the sale of the
     Firm Shares by the Underwriters. You, as Representatives of the several
     Underwriters, may cancel such option at any time prior to its expiration by
     giving written notice of such cancellation to the Company. To the extent,
     if any, that the option is exercised, payment for the Option Shares shall
     be made on the Option Closing Date in New York Clearing House funds by
     certified or bank cashier's check drawn to the order of the Company for the
     Option Shares to be sold by it and to the order of "GeoTel Communications
     Corporation, as Custodian" for the Option Shares to be sold by the Selling
     Shareholders listed on Schedule II against delivery of certificates
     therefor at the offices of Alex. Brown & Sons Incorporated, 135 East
     Baltimore Street, Baltimore, Maryland.
 
          (d) Certificates in negotiable form for the total number of the Option
     Shares to be sold hereunder by the Selling Shareholders have been placed in
     custody with the Company as custodian (the "Custodian") pursuant to the
     Custodian Agreement executed by each Selling Shareholder for delivery of
     any Option Shares to be sold hereunder by the Selling Shareholders. Each of
     the Selling Shareholders specifically agrees that any Option Shares
     represented by the certificates held in custody for the Selling
     Shareholders under the Custodian Agreement are subject to the interests of
     the Underwriters hereunder, that the arrangements made by the Selling
     Shareholders for such custody are to that extent irrevocable, and that the
     obligations of the Selling Shareholders hereunder shall not be terminable
     by any act or deed of the Selling Shareholders (or by any other person,
     firm or corporation including the Company, the Custodian or the
     Underwriters) or by operation of law (including the death of an individual
     Selling Shareholder or the dissolution of a corporate Selling Shareholder)
     or by the occurrence of any other event or events, except as set forth in
     the Custodian Agreement. If any such event should occur prior to the
     delivery to the Underwriters of the Option Shares hereunder, certificates
     for the Option Shares shall be delivered by the Custodian in accordance
     with the terms and conditions of this Agreement as if such event has not
     occurred. The Custodian is authorized to receive and acknowledge receipt of
     the proceeds of sale of the Option Shares held by it against delivery of
     such Option Shares.
 
     3. Offering by the Underwriters.
 
          It is understood that the several Underwriters are to make a public
     offering of the Firm Shares as soon as the Representatives deem it
     advisable to do so. The Firm Shares are to be initially offered to the
     public at the initial public offering price set forth in the Prospectus.
     The Representatives may from time to time thereafter change the public
     offering price and other selling terms. To the extent, if at all, that any
     Option Shares are purchased pursuant to Section 2 hereof, the Underwriters
     will offer them to the public on the foregoing terms.
 
          It is further understood that you will act as the Representatives for
     the Underwriters in the offering and sale of the Shares in accordance with
     a Master Agreement Among Underwriters entered into by you and the several
     other Underwriters.

     4.  Covenants of the Company and the Selling Shareholders.
 
          (a) The Company covenants and agrees with the several Underwriters
     that:
 
             (i) The Company will (A) use its best efforts to cause the
        Registration Statement to become effective or, if the procedure in Rule
        430A of the Rules and Regulations is followed, to prepare and timely
        file with the Commission under Rule 424(b) of the Rules and Regulations
        a Prospectus in a form approved by the Representatives containing
        information previously omitted at the time of effectiveness of the
        Registration Statement in reliance on Rule 430A of the Rules and
        Regulations, and (B) not file any amendment to the Registration
        Statement or supplement to the Prospectus of which the Representatives
        shall not previously have been advised and furnished with a copy or to
        which the Representatives shall have reasonably objected in writing or
        which is not in compliance with the Rules and Regulations.
 
             (ii) The Company will advise the Representatives promptly (A) when
        the Registration Statement or any post-effective amendment thereto shall
        have become effective, (B) of receipt of any comments from the
        Commission, (C) of any request of the Commission for amendment of the
        Registration Statement or for supplement to the Prospectus or for any
        additional information, and (D) of the issuance by the Commission of any
        stop order suspending the effectiveness of the Registration Statement or
        the use of the Prospectus or of the institution of any proceedings for
        that purpose. The Company will use its best efforts to prevent the
        issuance of any such stop order preventing or suspending the use of the
        Prospectus and to obtain as soon as possible the lifting thereof, if
        issued.
 
             (iii) The Company will cooperate with the Representatives in
        endeavoring to qualify the Shares for sale under the securities laws of
        such jurisdictions as the Representatives may reasonably have designated
        in writing and will make such applications, file such documents, and
        furnish such information as may be reasonably required for that purpose,
        provided the Company shall not be required to qualify as a foreign
        corporation or to file a general consent to service of process in any
        jurisdiction where it is not now so qualified or required to file such a
        consent. The Company will, from time to time, prepare and file such
        statements, reports and other documents as are or may be required to
        continue such qualifications in effect for so long a period as the
        Representatives may reasonably request for distribution of the Shares.
 
             (iv) The Company will deliver to, or upon the order of, the
        Representatives, from time to time, as many copies of any Preliminary
        Prospectus as the Representatives may reasonably request. The Company
        will deliver to, or upon the order of, the Representatives during the
        period when delivery of a Prospectus is required under the Act, as many
        copies of the Prospectus in final form, or as thereafter amended or
        supplemented, as the Representatives may reasonably request. The Company
        will deliver to the Representatives, at or before the Closing Date, four
        signed copies of the Registration Statement and all amendments thereto,
        including all exhibits filed therewith, and will deliver to the
        Representatives such number of copies of the Registration Statement
        (including such number of copies of the exhibits filed therewith that
        may reasonably be requested), and of all amendments thereto, as the
        Representatives may reasonably request.
 
             (v) The Company will comply with the Act and the Rules and
        Regulations, and the Securities Exchange Act of 1934, as amended (the
        "Exchange Act"), and the rules and regulations of the Commission
        thereunder, so as to permit the completion of the distribution of the
        Shares as contemplated in this Agreement and the Prospectus. If during
        the period in which a prospectus is required by law to be delivered by
        an Underwriter or dealer any event shall occur as a result of which, in
        the judgment of the Company or in the reasonable opinion of the
        Underwriters, it becomes necessary to amend or supplement the Prospectus
        in order to make the statements therein, in the light of the
        circumstances
 
                                        8
<PAGE>   9
 
        existing at the time the Prospectus is delivered to a purchaser, not
        misleading, or, if it is necessary at any time to amend or supplement
        the Prospectus to comply with any law, the Company promptly will either
        (A) prepare and file with the Commission an appropriate amendment to the
        Registration Statement or supplement to the Prospectus or (B) prepare
        and file with the Commission an appropriate filing under the Exchange
        Act which shall be incorporated by reference in the Prospectus, so that
        the Prospectus as so amended or supplemented will not, in the light of
        the circumstances when it is so delivered, be misleading, or so that the
        Prospectus will comply with the law.
 
             (vi) The Company will make generally available to its security
        holders, as soon as it is practicable to do so, but in any event not
        later than 15 months after the effective date of the Registration
        Statement, an earnings statement (which need not be audited) in
        reasonable detail, covering a period of at least 12 consecutive months
        beginning after the effective date of the Registration Statement, which
        earnings statement shall satisfy the requirements of Section 11(a) of
        the Act and Rule 158 of the Rules and Regulations and will advise you in
        writing when such statement has been so made available.
 
             (vii) The Company will, for a period of five years from the Closing
        Date, deliver to the Representatives copies of annual reports and copies
        of all other documents, reports and information furnished by the Company
        to its shareholders or filed with any securities exchange pursuant to
        the requirements of such exchange or with the Commission pursuant to the
        Act or the Exchange Act. The Company will deliver to the Representatives
        similar reports with respect to significant subsidiaries, as that term
        is defined in the Rules and Regulations, which are not consolidated in
        the Company's financial statements.
 
             (viii) No offering, sale, short sale or other disposition of any
        shares of Common Stock of the Company or other securities convertible
        into or exchangeable or exercisable for shares of Common Stock or
        derivative of Common Stock (or agreement for such) will be made for a
        period of 180 days after the date of this Agreement, directly or
        indirectly, by the Company otherwise than hereunder or with the prior
        written consent of Alex. Brown & Sons Incorporated, except that the
        Company may, without such consent, (A) issue shares upon the exercise of
        options outstanding on the date of this Agreement issued pursuant to its
        1995 Stock Option Plan, (B) issue shares of Common Stock upon the
        exercise of stock options and purchase rights granted after the date
        hereof under the 1995 Stock Option Plan and the 1996 Employee Stock
        Purchase Plan and (C) issue shares of Common Stock in respect of the
        Company's acquisition of the stock or assets of another entity so long
        as the shares so issued by the Company may not be resold until 180 days
        after the date of this Agreement. The Company shall not file with the
        Commission any registration statements (including without limitation any
        registration statements on Form S-8 or any successor form) with respect
        to any stock option, stock purchase, restricted stock or other similar
        plans until at least 90 days following the date of this Agreement.
 
             (ix) The Company will use its best efforts to have its Common Stock
        authorized for inclusion on the Nasdaq National Market.
 
             (x) The Company has caused each officer and director and specific
        shareholders of the Company to furnish to you, on or prior to the date
        of this Agreement, a letter or letters, in form and substance
        satisfactory to the Underwriters, pursuant to which each such person
        shall agree not to offer, sell, sell short or otherwise dispose of any
        shares of Common Stock of the Company or other capital stock of the
        Company, or any other securities convertible, exchangeable or
        exercisable for Common Stock or derivative of Common Stock owned by such
        person or request the registration for the offer or sale of any of the
        foregoing (or as to which such person has the right to direct the
        disposition of) for a period of 180 days after the date of this
        Agreement, directly or indirectly, except with the prior written consent
        of Alex. Brown & Sons Incorporated ("Lockup Agreements").
 
                                        9
<PAGE>   10
 
             (xi) The Company shall apply the net proceeds of its sale of the
        Shares as set forth in the Prospectus and shall file such reports with
        the Commission with respect to the sale of the Shares and the
        application of the proceeds therefrom as may be required in accordance
        with Rule 463 under the Act.
 
             (xii) The Company shall not invest, or otherwise use the proceeds
        received by the Company from its sale of the Shares in such a manner as
        would require the Company to register as an investment company under the
        1940 Act.
 
             (xiii) The Company will maintain a transfer agent and, if necessary
        under the jurisdiction of incorporation of the Company, a registrar for
        the Common Stock.
 
             (xiv) The Company will not take, directly or indirectly, any action
        designed to cause or result in, or that has constituted or might
        reasonably be expected to constitute, the stabilization or manipulation
        of the price of any securities of the Company.
 
          (b) Each of the Selling Shareholders covenants and agrees with the
     several Underwriters that:
 
             (i) No offering, sale, short sale or other disposition of any
        shares of Common Stock of the Company or other capital stock of the
        Company or other securities convertible, exchangeable or exercisable for
        Common Stock or derivative of Common Stock owned by the Selling
        Shareholder or request the registration for the offer or sale of any of
        the foregoing (or as to which the Selling Shareholder has the right to
        direct the disposition of) will be made for a period of 180 days after
        the date of this Agreement, directly or indirectly, by such Selling
        Shareholder otherwise than hereunder or with the prior written consent
        of Alex. Brown & Sons Incorporated.
 
             (ii) In order to document the Underwriters' compliance with the
        reporting and withholding provisions of the Tax Equity and Fiscal
        Responsibility Act of 1982 and the Interest and Dividend Tax Compliance
        Act of 1983 with respect to the transactions herein contemplated, each
        of the Selling Shareholders agrees to deliver to you prior to or at the
        Closing Date a properly completed and executed United States Treasury
        Department Form W-9 (or other applicable form or statement specified by
        Treasury Department regulations in lieu thereof).
 
             (iii) Such Selling Shareholder will not take, directly or
        indirectly, any action designed to cause or result in, or that has
        constituted or might reasonably be expected to constitute, the
        stabilization or manipulation of the price of any securities of the
        Company.
 
     5.  Costs and Expenses.
 
     The Company will pay all costs, expenses and fees incident to the
performance of the obligations of the Sellers under this Agreement, including,
without limiting the generality of the foregoing, the following: accounting fees
of the Company; the fees and disbursements of counsel for the Company and the
Selling Shareholders; the cost of printing and delivering to, or as requested
by, the Underwriters copies of the Registration Statement, Preliminary
Prospectuses, the Prospectus, this Agreement, the Underwriters' Selling
Memorandum, the Underwriters' Invitation Letter, the Listing Application, the
Custodian Agreement and related Power of Attorney, the Blue Sky Survey and any
supplements or amendments thereto; the filing fees of the Commission; the filing
fees and expenses (including legal fees and disbursements) incident to securing
any required review by the NASD of the terms of the sale of the Shares; the
Listing Fee of the Nasdaq National Market; and the expenses, including the fees
and disbursements of counsel for the Underwriters, incurred in connection with
the qualification of the Shares under state securities or Blue Sky laws. To the
extent, if at all, that any of the Selling Shareholders engage special legal
counsel to represent them in connection with this offering, the fees and
expenses of such counsel shall be borne by such Selling Shareholders. Any
transfer taxes imposed on the sale of the Shares to the several Underwriters
will be paid by the
 
                                       10
<PAGE>   11
 
Sellers pro rata. The Sellers shall not, however, be required to pay for any of
the Underwriters expenses (other than those related to qualification under NASD
regulation and state securities or Blue Sky laws) except that, if this Agreement
shall not be consummated because the conditions in Section 6 hereof are not
satisfied, or because this Agreement is terminated by the Representatives
pursuant to Section 11 hereof, or by reason of any failure, refusal or inability
on the part of the Company or the Selling Shareholders to perform any
undertaking or satisfy any condition of this Agreement or to comply with any of
the terms hereof on their part to be performed, unless such failure to satisfy
said condition or to comply with said terms be due to the default or omission of
any Underwriter, then the Company shall reimburse the several Underwriters for
reasonable out-of-pocket expenses, including fees and disbursements of counsel,
reasonably incurred in connection with investigating, marketing and proposing to
market the Shares or in contemplation of performing their obligations hereunder;
but the Company and the Selling Shareholders shall not in any event be liable to
any of the several Underwriters for damages on account of loss of anticipated
profits from the sale by them of the Shares.
 
     6.  Conditions to Obligations of the Underwriters.
 
     The several obligations of the Underwriters to purchase the Firm Shares on
the Closing Date and the Option Shares, if any, on the Option Closing Date are
subject to the accuracy, as of the Closing Date or the Option Closing Date, as
the case may be, of the representations and warranties of the Company and the
Selling Shareholders contained herein, and to the performance by the Company and
the Selling Shareholders of their covenants and obligations hereunder and to the
following additional conditions:
 
          (a) The Registration Statement and all post-effective amendments
     thereto shall have become effective and any and all filings required by
     Rule 424 and Rule 430A of the Rules and Regulations shall have been made,
     and any request of the Commission for additional information (to be
     included in the Registration Statement or otherwise) shall have been
     disclosed to the Representatives and complied with to their reasonable
     satisfaction. No stop order suspending the effectiveness of the
     Registration Statement, as amended from time to time, shall have been
     issued and no proceedings for that purpose shall have been taken or, to the
     knowledge of the Company or the Selling Shareholders, shall be contemplated
     by the Commission and no injunction, restraining order, or order of any
     nature by a federal or state court of competent jurisdiction shall have
     been issued as of the Closing Date which would prevent the issuance of the
     Shares.
 
          (b) The Representatives shall have received on the Closing Date or the
     Option Closing Date, as the case may be, the opinion of Hutchins, Wheeler &
     Dittmar, A Professional Corporation, counsel for the Company and the
     Selling Shareholders, dated the Closing Date or the Option Closing Date, as
     the case may be, addressed to the Underwriters (and stating that it may be
     relied upon by counsel to the Underwriters) to the effect that:
 
             (i) The Company has been duly organized and is validly existing as
        a corporation in good standing under the laws of the State of Delaware,
        with corporate power and authority to own or lease its properties and
        conduct its business as described in the Registration Statement; and the
        Company is duly qualified to transact business in each of the
        jurisdictions listed on Schedule III attached hereto based solely upon
        certificates from the respective Secretary of State in such
        jurisdictions.
 
             (ii) The Company has authorized and outstanding capital stock as
        set forth under the caption "Capitalization" in the Prospectus other
        than changes resulting from the exercise of options outstanding as of
        the date of the Prospectus and described therein; the authorized shares
        of the Company's Common Stock have been duly authorized; the outstanding
        shares of the Company's Common Stock, including the Option Shares to be
        sold by the Selling Shareholders, have been duly authorized and validly
        issued and are fully paid and non-assessable; all of the Shares conform,
        in all material respects, to the
 
                                       11
<PAGE>   12
 
        description thereof contained in the Prospectus under the caption
        "Description of Capital Stock -- Common Stock"; the certificates for the
        Shares, assuming they are in the form filed with the Commission, are in
        due and proper form; the shares of Common Stock, including the Option
        Shares, if any, to be sold by the Company pursuant to this Agreement
        have been duly authorized and will be validly issued, fully paid and
        non-assessable when issued and paid for as contemplated by this
        Agreement; and no preemptive rights of shareholders exist pursuant to
        the Company's charter or by-laws or any agreement to which the Company
        is a party with respect to any of the Shares or the issue or sale
        thereof.
 
             (iii) Except as described in or contemplated by the Prospectus, to
        the knowledge of such counsel, there are no outstanding securities of
        the Company convertible or exchangeable into any shares of capital stock
        of the Company and there are no outstanding options or warrants
        obligating the Company to issue any shares of its capital stock or any
        securities convertible or exchangeable into any shares of such stock;
        and except as described in the Prospectus, to the knowledge of such
        counsel, no holder of any securities of the Company or any other person
        has the right, contractual or otherwise, which has not been satisfied or
        effectively waived, to require registration under the Act of any shares
        of Common Stock or other securities of the Company.
 
             (iv) We have been advised by the Commission that the Registration
        Statement has become effective under the Act and, to the knowledge of
        such counsel, no stop order proceedings with respect thereto have been
        instituted or are pending or threatened under the Act.
 
             (v) The Registration Statement, the Prospectus and each amendment
        or supplement thereto comply as to form in all material respects with
        the requirements of the Act and the applicable Rules and Regulations
        thereunder (except that such counsel need express no opinion as to the
        financial statements, schedules and other financial or statistical
        information included therein).
 
             (vi) The statements under the captions "Risk Factors -- Shares
        Eligible for Future Sale; Registration Rights," "Risk Factors -- Certain
        Anti-Takeover Provisions Affecting Stockholders," "Management -- Stock
        Plans," "Management -- Executive Incentive Program,"
        "Management -- Limitation of Liability; Indemnification of Directors and
        Officers," "Certain Transactions -- Certain Stock Transactions,"
        "Description of Capital Stock" and "Shares Eligible for Future Sale" in
        the Prospectus, insofar as such statements constitute a summary of
        documents referred to therein or matters of law, fairly and correctly
        summarize and present in all material respects the information called
        for with respect to such documents and matters.
 
             (vii) Such counsel does not know of any contracts or documents
        required to be filed as exhibits to the Registration Statement or
        described in the Registration Statement or the Prospectus which are not
        so filed or described as required, and such contracts and documents as
        are summarized in the Registration Statement or the Prospectus are
        fairly summarized in all material respects.
 
             (viii) Such counsel knows of no material legal or governmental
        proceedings pending or threatened against the Company except as set
        forth in the Prospectus.
 
             (ix) The execution and delivery of this Agreement and the
        consummation of the transactions herein contemplated do not conflict
        with or result in a breach of any of the terms or provisions of, or
        constitute a default under, the Certificate of Incorporation or By-laws
        of the Company, or any agreement or instrument listed as an Exhibit to
        the Registration Statement.
 
             (x) This Agreement has been duly authorized, executed and delivered
        by the Company.
 
                                       12
<PAGE>   13
 
             (xi) No approval, consent, order, authorization, designation,
        declaration or filing by or with any regulatory, administrative or other
        governmental body is necessary in connection with the execution and
        delivery of this Agreement and the consummation of the transactions
        herein contemplated (other than as may be required by the NASD or as
        required by state securities and Blue Sky laws, as to which such counsel
        need express no opinion) except such as have been obtained or made,
        specifying the same.
 
             (xii) The Company is not, and will not become, as a result of the
        consummation of the transactions contemplated by this Agreement, and
        application of the net proceeds therefrom as described in the
        Prospectus, required to register as an investment company under the 1940
        Act.
 
             (xiii) Each of this Agreement, the Custodian Agreement and the
        related Power of Attorney has been duly authorized, executed and
        delivered by or on behalf of each of the Selling Shareholders.
 
             (xiv) Each Selling Shareholder has full legal right, power and
        authority, and any approval required by law (other than as required by
        state securities and Blue Sky laws, as to which such counsel need
        express no opinion), to sell, assign, transfer and deliver the portion
        of the Option Shares to be sold by such Selling Shareholder under this
        Agreement.
 
             (xv) The Custodian Agreement and the Power of Attorney executed and
        delivered by each Selling Shareholder are valid, binding and irrevocable
        instruments legally sufficient for the purposes intended.
 
             (xvi) The Underwriters (assuming that they are bona fide purchasers
        within the meaning of the Uniform Commercial Code) have acquired good
        and marketable title to the Option Shares being sold by each Selling
        Shareholder on the Option Closing Date, free and clear of all liens,
        encumbrances and security interests.
 
     In rendering such opinion, Hutchins, Wheeler & Dittmar, A Professional
Corporation, may rely as to matters governed by the laws of states other than
the Commonwealth of Massachusetts, the Delaware General Corporation Law or
federal laws on local counsel in such jurisdictions and as to the matters set
forth in subparagraphs (xiii), (xiv) and (xv) on opinions of other counsel
representing the respective Selling Shareholders, provided that in each case
Hutchins, Wheeler & Dittmar, A Professional Corporation, shall state that they
believe that they and the Underwriters are justified in relying on the opinions
of such other counsel. In addition to the matters set forth above, such opinion
shall also include a statement to the effect that nothing has come to the
attention of such counsel which leads them to believe that (i) the Registration
Statement, at the time it became effective under the Act (but after giving
effect to any modifications incorporated therein pursuant to Rule 430A under the
Act) and as of the Closing Date or the Option Closing Date, as the case may be,
contained an 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, and (ii) the Prospectus, or any supplement thereto, on the date
it was filed pursuant to Rule 424(b) and as of the Closing Date or the Option
Closing Date, as the case may be, contained an untrue statement of a material
fact or omitted to state a material fact necessary in order to make the
statements, in the light of the circumstances under which they are made, not
misleading (except that such counsel need express no view as to financial
statements, schedules and other financial and statistical information included
therein). With respect to such statement, Hutchins, Wheeler & Dittmar, A
Professional Corporation, may state that their belief is based upon the
procedures set forth therein, but is without independent check and verification.
 
          (c) The Representatives shall have received from Hale and Dorr,
     counsel for the Underwriters, an opinion dated the Closing Date or the
     Option Closing Date, as the case may be, substantially to the effect
     specified in subparagraphs (ii), (iii), (iv) and (xi) of paragraph (b) of
     this Section 6, and that the Company is a duly organized and validly
     existing corporation
 
                                       13
<PAGE>   14
 
     under the laws of the State of Delaware. In rendering such opinion, Hale
     and Dorr may rely as to all matters governed other than by the laws of the
     Commonwealth of Massachusetts, the Delaware General Corporation Law or
     federal laws, and as to matters relating to the Selling Shareholders, on
     the opinion of counsel referred to in paragraph (b) of this Section 6. In
     addition to the matters set forth above, such opinion shall also include a
     statement to the effect that nothing has come to the attention of such
     counsel which leads them to believe that (i) the Registration Statement, or
     any amendment thereto, as of the time it became effective under the Act
     (but after giving effect to any modifications incorporated therein pursuant
     to Rule 430A under the Act), as of the Closing Date or the Option Closing
     Date, as the case may be, contained an 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, and (ii) the
     Prospectus, or any supplement thereto, on the date it was filed pursuant to
     the Rules and Regulations and as of the Closing Date or the Option Closing
     Date, as the case may be, contained an untrue statement of a material fact
     or omitted to state a material fact, necessary in order to make the
     statements therein, in the light of the circumstances under which they are
     made, not misleading (except that such counsel need express no view as to
     financial statements, schedules and other financial information included
     therein). With respect to such statement, Hale and Dorr may state that
     their belief is based upon the procedures set forth therein, but is without
     independent check and verification.
 
          (d) The Representatives shall have received at or prior to the Closing
     Date from Hale and Dorr a memorandum or summary, in form and substance
     satisfactory to the Representatives, with respect to the qualification for
     offering and sale by the Underwriters of the Shares under the state
     securities or Blue Sky laws of such jurisdictions as the Representatives
     may reasonably have designated to the Company.
 
          (e) You shall have received, on each of the date hereof, the Closing
     Date and the Option Closing Date, as the case may be, a letter dated the
     date hereof, the Closing Date or the Option Closing Date, as the case may
     be, in form and substance satisfactory to you, of Coopers & Lybrand L.L.C.
     confirming that they are independent public accountants within the meaning
     of the Act and the applicable published Rules and Regulations thereunder
     and stating that in their opinion the financial statements and schedules
     examined by them and included in the Registration Statement comply in form
     in all material respects with the applicable accounting requirements of the
     Act and the related published Rules and Regulations; and containing such
     other statements and information as is ordinarily included in accountants'
     "comfort letters" to Underwriters with respect to the financial statements
     and certain financial and statistical information contained in the
     Registration Statement and Prospectus.
 
          (f) The Representatives shall have received on the Closing Date or the
     Option Closing Date, as the case may be, a certificate or certificates of
     the President and Chief Executive Officer and the Vice President, Finance
     and Chief Financial Officer of the Company to the effect that, as of the
     Closing Date or the Option Closing Date, as the case may be, each of them
     severally represents as follows:
 
             (i) The Registration Statement has become effective under the Act
        and no stop order suspending the effectiveness of the Registrations
        Statement has been issued, and no proceedings for such purpose have been
        taken or are, to his knowledge, contemplated by the Commission.
 
             (ii) He does not know of any litigation instituted or threatened
        against the Company of a character required to be disclosed in the
        Registration Statement which is not so disclosed; he does not know of
        any material contract required to be filed as an exhibit to the
        Registration Statement which is not so filed; and the representations
        and warranties of the
 
                                       14
<PAGE>   15
 
        Company contained in Section 1 hereof are true and correct as of the
        Closing Date or the Option Closing Date, as the case may be.
 
             (iii) All filings required to have been made pursuant to Rules 424
        or 430A under the Act have been made.
 
             (iv) He has carefully examined the Registration Statement and the
        Prospectus and, in his opinion, as of the effective date of the
        Registration Statement, the statements contained in the Registration
        Statement were true and correct in all material respects, and such
        Registration Statement and Prospectus did not omit to state a material
        fact required to be stated therein or necessary in order 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, no event has occurred which should have been set
        forth in a supplement to or an amendment of the Prospectus which has not
        been so set forth in such supplement or amendment.
 
             (v) Since the respective dates as of which information is given in
        the Registration Statement and Prospectus, there has not been any
        material adverse change or any development involving a prospective
        material adverse change in or affecting the condition (financial or
        otherwise) of the Company or the earnings, business, management,
        properties, assets, operations or condition (financial or otherwise) of
        the Company, whether or not arising in the ordinary course of business.
 
          (g) The Company and, in the case of any Option Closing, the Selling
     Shareholders shall have furnished to the Representatives such further
     certificates and documents confirming the representations and warranties,
     covenants and conditions contained herein and related matters as the
     Representatives may reasonably have requested.
 
          (h) The Firm Shares and Option Shares, if any, shall have been
     approved for designation upon notice of issuance on the Nasdaq National
     Market.
 
          (i) The Lockup Agreements described in Section 4(a)(x) shall be in
     full force and effect.
 
     The opinions and certificates mentioned in this Agreement shall be deemed
to be in compliance with the provisions hereof only if they are in all material
respects satisfactory to the Representatives and to Hale and Dorr, counsel for
the Underwriters.
 
     If any of the conditions hereinabove provided for in this Section 6 shall
not have been fulfilled when and as required by this Agreement to be fulfilled,
the obligations of the Underwriters hereunder may be terminated by the
Representatives by notifying the Company and the Selling Shareholders of such
termination in writing or by telegram at or prior to the Closing Date or the
Option Closing Date, as the case may be. In such event, the Selling
Shareholders, the Company and the Underwriters shall not be under any obligation
to each other (except to the extent provided in Sections 5 and 8 hereof).
 
     7.  Conditions to the Obligations of the Sellers.
 
     The obligations of the Sellers to sell and deliver the portion of the
Shares required to be delivered as and when specified in this Agreement are
subject to the conditions that at the Closing Date or the Option Closing Date,
as the case may be, no stop order suspending the effectiveness of the
Registration Statement shall have been issued and in effect or proceedings
therefor initiated or threatened.
 
     8.  Indemnification.
 
          (a) The Company and the Selling Shareholders, jointly and severally,
     agree to indemnify and hold harmless each Underwriter and each person, if
     any, who controls any Underwriter within the meaning of the Act, against
     any losses, claims, damages or liabilities to which such Underwriter or any
     such controlling person may become subject under the Act or otherwise,
 
                                       15
<PAGE>   16
 
     insofar as such losses, claims, damages or liabilities (or actions or
     proceedings in respect thereof) arise out of or are based upon (i) any
     untrue statement or alleged untrue statement of any material fact contained
     in the Registration Statement, any Preliminary Prospectus, the Prospectus
     or any amendment or supplement thereto, or (ii) 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, in the light of
     the circumstances under which they were made; and will reimburse each
     Underwriter and each such controlling person upon demand for any legal or
     other expenses reasonably incurred by such Underwriter and each such
     controlling person in connection with investigating or defending any such
     loss, claim, damage, liability, action or proceeding or in responding to a
     subpoena or governmental inquiry related to the offering of the Shares,
     whether or not such Underwriter or controlling person is a party to any
     such action or proceeding; provided, however, that the Company and the
     Selling Shareholders will not be liable in any such case to the extent that
     any such loss, claim, damage or liability arises out of or is based upon an
     untrue statement or alleged untrue statement, or omission or alleged
     omission, made in the Registration Statement, any Preliminary Prospectus,
     the Prospectus, or such amendment or supplement, in reliance upon and in
     conformity with written information furnished to the Company by or through
     the Representatives specifically for use in the preparation thereof; and
     provided further, that the indemnification agreement contained in this
     Section 8(a) with respect to any Preliminary Prospectus, or the Prospectus
     after it has been amended or supplemented, shall not inure to the benefit
     of any Underwriter (or any person controlling such Underwriter) from whom
     the person asserting such loss, claim, damage or liability shall have
     purchased Shares that are the subject thereof if, after copies thereof have
     been delivered by the Company to such Underwriter, such Underwriter shall
     have failed to send or give a copy of the final Prospectus or the
     Prospectus as then amended or supplemented, as the case may be, to such
     person at or prior to the confirmation of said sale of such Shares to such
     person, and if such loss, claim, damage or liability would not have arisen
     but for such failure. In no event, however, shall the liability of any
     Selling Shareholder for indemnification under this Section 8(a) exceed the
     lesser of (i) the Selling Shareholder's pro rata portion of such losses,
     claims, damages and liabilities, determined by comparing the number of
     Shares sold by the Selling Shareholder to the total number of Shares sold
     hereunder, and (ii) the proceeds received by such Selling Shareholder from
     the Underwriters in the offering. This indemnity agreement will be in
     addition to any liability which the Company or the Selling Shareholders may
     otherwise have.
 
          (b) Each Underwriter severally and not jointly will indemnify and hold
     harmless the Company, each of its directors, each of its officers who have
     signed the Registration Statement, the Selling Shareholders and each
     person, if any, who controls the Company or the Selling Shareholders within
     the meaning of the Act, against any losses, claims, damages or liabilities
     to which the Company or any such director, officer, Selling Shareholder or
     controlling person may become subject under the Act or otherwise, insofar
     as such losses, claims, damages or liabilities (or actions or proceedings
     in respect thereof) arise out of or are based upon (i) any untrue statement
     or alleged untrue statement of any material fact contained in the
     Registration Statement, any Preliminary Prospectus, the Prospectus or any
     amendment or supplement thereto, or (ii) the omission or the alleged
     omission to state therein a material fact required to be stated therein or
     necessary to make the statements therein not misleading in the light of the
     circumstances under which they were made; and will reimburse any legal or
     other expenses reasonably incurred by the Company or any such director,
     officer, Selling Shareholder or controlling person in connection with
     investigating or defending any such loss, claim, damage, liability, action
     or proceeding; provided, however, that each Underwriter will be liable in
     each case to the extent, but only to the extent, that such untrue statement
     or alleged untrue statement or omission or alleged omission has been made
     in the Registration Statement, any Preliminary Prospectus, the Prospectus
     or such amendment or supplement, in reliance upon and in conformity with
     written information furnished to the Company by or through the Representa-
 
                                       16
<PAGE>   17
 
     tives specifically for use in the preparation thereof. This indemnity
     agreement will be in addition to any liability which such Underwriter may
     otherwise have.
 
          (c) In case any proceeding (including any governmental investigation)
     shall be instituted involving any person in respect of which indemnity may
     be sought pursuant to this Section 8, such person (the "indemnified party")
     shall promptly notify the person against whom such indemnity may be sought
     (the "indemnifying party") in writing. No indemnification provided for in
     Section 8(a) or (b) shall be available to any party who shall fail to give
     notice as provided in this Section 8(c) if the party to whom notice was not
     given was unaware of the proceeding to which such notice would have related
     and was materially prejudiced by the failure to give such notice, but the
     failure to give such notice shall not relieve the indemnifying party or
     parties from any liability which it or they may have to the indemnified
     party for contribution or otherwise than on account of the provisions of
     Section 8(a) or (b). In case any such proceeding shall be brought against
     any indemnified party and it shall notify the indemnifying party of the
     commencement thereof, the indemnifying party shall be entitled to
     participate therein and, to the extent that it shall wish, jointly with any
     other indemnifying party similarly notified, to assume the defense thereof,
     with counsel satisfactory to such indemnified party and shall pay as
     incurred the fees and disbursements of such counsel related to such
     proceeding. In any such proceeding, any indemnified party shall have the
     right to retain its own counsel at its own expense. Notwithstanding the
     foregoing, the indemnifying party shall pay as incurred the fees and
     expenses of the counsel retained by the indemnified party in the event (i)
     the indemnifying party and the indemnified party shall have mutually agreed
     to the retention of such counsel, (ii) the named parties to any such
     proceeding (including any impleaded parties) include both the indemnifying
     party and the indemnified party and representation of both parties by the
     same counsel would be inappropriate due to a conflict of interest between
     them, or (iii) the indemnifying party shall have failed to assume the
     defense and employ counsel acceptable to the indemnified party within a
     reasonable period of time after notice of commencement of the action. It is
     understood that the indemnifying party shall not, in connection with any
     proceeding or related proceedings in the same jurisdiction, be liable for
     the reasonable fees and expenses of more than one separate firm for all
     such indemnified parties. Such firm shall be designated in writing by you
     in the case of parties indemnified pursuant to Section 8(a) and by the
     Company and the Selling Shareholders in the case of parties indemnified
     pursuant to Section 8(b). The indemnifying party shall not be liable for
     any settlement of any proceeding effected without its written consent but,
     if settled with such consent or if there be a final judgment for the
     plaintiff, the indemnifying party agrees to indemnify the indemnified party
     from and against any loss or liability by reason of such settlement or
     judgment. In addition, the indemnifying party will not, without the prior
     written consent of the indemnified party, settle or compromise or consent
     to the entry of any judgment in any pending or threatened claim, action or
     proceeding of which indemnification may be sought hereunder (whether or not
     any indemnified party is an actual or potential party to such claim, action
     or proceeding) unless such settlement, compromise or consent includes an
     unconditional release of each indemnified party from all liability arising
     out of such claim, action or proceeding.
 
          (d) If the indemnification provided for in this Section 8 is
     unavailable to or insufficient to hold harmless an indemnified party under
     Section 8(a) or (b) above in respect of any losses, claims, damages or
     liabilities (or actions or proceedings in respect thereof) referred to
     therein, then each indemnifying party shall contribute to the amount paid
     or payable by such indemnified party as a result of such losses, claims,
     damages or liabilities (or actions or proceedings in respect thereof) in
     such proportion as is appropriate to reflect the relative benefits received
     by the Company and the Selling Shareholders on the one hand and the
     Underwriters on the other from the offering of the Shares. If, however, the
     allocation provided by the immediately preceding sentence is not permitted
     by applicable law, then each indemnifying party shall contribute to such
     amount paid or payable by such indemnified party in such proportion as is
     appropriate to reflect not only such relative benefits but also the
     relative fault of the Company
 
                                       17
<PAGE>   18
 
     and the Selling Shareholders on the one hand and the Underwriters on the
     other in connection with the statements or omissions which resulted in such
     losses, claims, damages or liabilities (or actions or proceedings in
     respect thereof), as well as any other relevant equitable considerations.
     The relative benefits received by the Company and the Selling Shareholders
     on the one hand and the Underwriters on the other shall be deemed to be in
     the same proportion as the total net proceeds from the offering (before
     deducting expenses) received by the Company and the Selling Shareholders
     bear to the total underwriting discounts and commissions received by the
     Underwriters, in each case as set forth in the table on the cover page of
     the Prospectus. The relative fault shall be determined by reference to,
     among other things, whether the untrue or alleged untrue statement of a
     material fact or the omission or alleged omission to state a material fact
     relates to information supplied by the Company or the Selling Shareholders
     on the one hand or the Underwriters on the other and the parties' relative
     intent, knowledge, access to information and opportunity to correct or
     prevent such statement or omission.
 
          The Company, the Selling Shareholders and the Underwriters agree that
     it would not be just and equitable if contributions pursuant to this
     Section 8(d) were determined by pro rata allocation (even if the
     Underwriters were treated as one entity for such purpose) or by any other
     method of allocation which does not take account of the equitable
     considerations referred to above in this Section 8(d). The amount paid or
     payable by an indemnified party as a result of the losses, claims, damages
     or liabilities (or actions or proceedings in respect thereof) referred to
     above in this Section 8(d) shall be deemed to include any legal or other
     expenses reasonably incurred by such indemnified party in connection with
     investigating or defending any such action or claim. Notwithstanding the
     provisions of this Section 8(d), (i) no Underwriter shall be required to
     contribute any amount in excess of the underwriting discounts and
     commissions applicable to the Shares purchased by such Underwriter, (ii) no
     person guilty of fraudulent misrepresentation (within the meaning of

     Selling Shareholder shall be required to contribute any amount in excess of

     from such court may be served upon him or it by any other contributing

     indemnity and contribution agreements contained in this Section 8 and the
     representations and warranties of the Company and the Selling Shareholders
     set forth in this Agreement shall remain operative and in full force and
     effect, regardless of (i) any investigation made by or on behalf of any
     Underwriter or any person controlling any Underwriter, the Company, its
     directors or officers or any persons controlling the Company, (ii)
     acceptance of any Shares and payment therefor hereunder, and (iii) any
     termination of this Agreement. A successor to any Underwriter, or to the
     Company, its directors or officers, or any person controlling the Company,
     shall be entitled to the benefits of the indemnity, contribution and

     9.  Default by Underwriters.
 
     If on the Closing Date or the Option Closing Date, as the case may be, any
Underwriter shall fail to purchase and pay for the portion of the Shares which
such Underwriter has agreed to purchase and pay for on such date (otherwise than
by reason of any default on the part of the Company or a Selling Shareholder),
you, as Representatives of the Underwriters, shall use your reasonable efforts
to procure within 36 hours thereafter one or more of the other Underwriters, or
any others, to purchase from the Company and the Selling Shareholders such
amounts as may be agreed upon and upon the terms set forth herein, the Firm
Shares or Option Shares, as the case may be, which the defaulting Underwriter or
Underwriters failed to purchase. If during such 36 hours you, as such
Representatives, shall not have procured such other Underwriters, or any others,
to purchase the Firm Shares or Option Shares, as the case may be, agreed to be
purchased by the defaulting Underwriter or Underwriters, then (a) if the
aggregate number of shares with respect to which such default shall occur does
not exceed 10% of the Firm Shares or Option Shares, as the case may be, covered
hereby, the other Underwriters shall be obligated, severally, in proportion to
the respective numbers of Firm Shares or Option Shares, as the case may be,
which they are obligated to purchase hereunder, to purchase the Firm Shares or
Option Shares, as the case may be, which such defaulting Underwriter or
Underwriters failed to purchase, or (b) if the aggregate number of shares of
Firm Shares or Option Shares, as the case may be, with respect to which such
default shall occur exceeds 10% of the Firm Shares or Option Shares, as the case
may be, covered hereby, the Company and the Selling Shareholders or you as the
Representatives of the Underwriters will have the right, by written notice given
within the next 36-hour period to the parties to this Agreement, to terminate
this Agreement without liability on the part of the non-defaulting Underwriters
or of the Company or of the Selling Shareholders except to the extent provided
in Section 8 hereof. In the event of a default by any Underwriter or
Underwriters, as set forth in this Section 9, the Closing Date or Option Closing
Date, as the case may be, may be postponed for such period, not exceeding seven
days, as you, as Representatives, may determine in order that the required
changes in the Registration Statement or in the Prospectus or in any other
documents or arrangements may be effected. The term "Underwriter" includes any
person substituted for a defaulting Underwriter. Any action taken under this
Section 9 shall not relieve any defaulting Underwriter from liability in respect
of any default of such Underwriter under this Agreement.

incorporates the Program in a value added manner and where the Program does not
constitute the predominant/primary market focus of the application. Licensee has
the right to enter into licensing and/or sub-licensing agreements with
customers, vars, distributors and strategic partners for Licensee's developed

          A. During the Term, any division, segment or other business unit or
group within Licensee, as well as any Licensee Affiliate or Alliance Partner as
provided in this Section 2.1, shall be entitled to license Programs and/or
obtain Technical Support, Support Services, or any other Services available
hereunder from GeoTel on a worldwide basis pursuant to, and subject to, the
terms and conditions of this Agreement, including specifically but without
limitation the volume discounts and pricing afforded hereunder, and the
limitation of liability set forth in Article 10, by issuing Orders for such
Programs and/or Services pursuant to Article 6, but as to any such Order
submitted by an Alliance Partner, subject to the Licensee consent requirement
specified in Section 2.2 A.

          B. Exhibit A sets forth a list of Licensee Affiliates and Alliance 
Partners as of the Effective Date. Licensee may from time to time notify GeoTel
of changes to said Exhibit A which shall promptly be amended accordingly by the
Parties; provided, however, that the addition of any entity as an Alliance
Partner by virtue of such entity complying with the requirements of Subitems
(ii) (x) or (ii)(y) of Section 1.2 shall be subject to the prior consent of
GeoTel, which consent shall not be unreasonably withheld or delayed. GeoTel
acknowledges and agrees that since Exhibit A may not be a complete list of all
Licensee Affiliates and Alliance Partners at any given time during the Term,
Licensee shall be entitled at any given time to certify in writing to GeoTel
that one or more additional entities not then listed on Exhibit A are Licensee
Affiliates or Alliance Partners and GeoTel shall afford such additional entities
the right to purchase Programs and/or Services as otherwise provided under this
Article 2 pending amendment of Exhibit A, but subject as to any such Alliance
Partner to the Licensee consent specified in Section 2.2 A.

     2.2  ORDERS BY AFFILIATES AND ALLIANCE PARTNERS.

          A.    1. GeoTel shall not accept any Order submitted against this 
Agreement by an Alliance Partner unless: (i) such Order expressly references
this Agreement and this Article 2, and (ii) GeoTel receives the prior express
written consent of Licensee, which consent specifically refers to the proposed
Order, the ordering Alliance Partner, and this Section 2 of this Agreement, and
is signed on behalf of Licensee by both a Senior Vice President of Licensee and
Licensee's Chief Technology Counsel, provided that such consent of Licensee may
be granted or withheld at the sole discretion of Licensee. Under no
circumstances shall Licensee be deemed to be a party to, to have any liability
or obligation whatsoever in connection with, or to be a guarantor of the
obligations under, any Order submitted by an Alliance Partner against this
Agreement as to which Licensee has not provided to GeoTel the prior written
consent required by this Section and which otherwise fails to comply with
Subitem (i) of this Section.

                2. Any conforming Order submitted by an Alliance Partner as to
which


<PAGE>   7



Licensee has consented as required pursuant to Section 2.2 A shall be accepted
by GeoTel pursuant to Section 6.2 but subject to Section 2.2 C below.

          B.    1. Software programs and services obtained by an Alliance 
Partner from GeoTel pursuant to agreement separately negotiated between such
Alliance Partner and GeoTel and not resulting from Section 2.1 A, shall not
accrue to the benefit of, or be credited to, Licensee for purposes of this
Agreement, including without limitation for purposes of Licensee's volume
discount, pricing or Purchase Commitment hereunder, nor shall such Alliance
Partner be afforded the benefit under such separate agreement of the volume
discounts and pricing otherwise available hereunder unless otherwise agreed to
between the Alliance Partner and GeoTel.

                2. Software programs and services obtained by a Licensee 
Affiliate from GeoTel pursuant to agreement separately negotiated between such
Affiliate and GeoTel and not resulting from Section 2.1 A, shall nonetheless
accrue to the benefit of, and be credited to, Licensee for purposes of
Licensee's volume discount, pricing and Purchase Commitment hereunder, and such
Affiliate shall be entitled to the pricing and volume discounts available
hereunder as to any purchases pursuant to such separate agreement but shall
otherwise not be afforded the benefit of any other terms and conditions
hereunder unless expressly agreed by the Affiliate and GeoTel.

                3. Under no circumstances shall Licensee be deemed to be a party
to, to have any liability or obligation whatsoever in connection with, or to be
a guarantor of the obligations of any Alliance Partner or Licensee Affiliate
under any such separate agreement between such Alliance Partner or Affiliate
with GeoTel as referred to in Sections 2.2 B 1 and 2.

          C. Notwithstanding the provisions of Sections 2.2 A 2 and 6.2, GeoTel
may nonetheless reject the Order of a Licensee Affiliate or the Order of an
Alliance Partner otherwise consented to by Licensee as required pursuant to
Section 2.2 A 1, where the site of the Designated Computer for use of Programs
is located outside of North America and GeoTel has a reasonable basis to believe
that it will be unable to adequately provide Technical Support for such Programs
in such location, provided that such rejection and reasonable basis are
communicated by GeoTel in writing to the ordering party promptly after receipt
of the Order.

     2.3  ACCRUAL OF PURCHASES. All Programs licensed to, and Services
obtained by, any Affiliate or Alliance Partner resulting from Sections 2.1 A or
2.2 B 2 shall accrue to the benefit of, and be credited to, Licensee for
purposes of (i) determining pricing and volume discounts under this Agreement,
and (ii) fulfillment by Licensee of the Purchase Commitment, as defined in
Section 2.4. Nothing herein shall limit the right of Licensee or any Affiliate
or Alliance Partner from obtaining at any time from any third party the same or
similar software and/or services as may be obtained or available hereunder or
obtaining from GeoTel more favorable pricing than the pricing otherwise
available hereunder.

     2.4  PURCHASE COMMITMENT; NO OTHER MINIMUM COMMITMENTS.
          -------------------------------------------------

        A.  Purchase Commitment.  Licensee agrees that during each of the three
consecutive twelve (12) month periods during the Initial Term, the first such
twelve month period commencing with the Effective Date and each such
consecutive twelve month period being hereinafter referred to as a "Contract
Year", a minimum of   *  in Eligible Purchases from GeoTel shall be made
pursuant to this Agreement, such minimum purchase obligations for each of the
three Contract Years hereinafter being referred to individually or
collectively, as the context requires, as the "Purchase Commitment" and such
Eligible Purchases being defined and valued as provided in Section 2.4 B.

        B.  Eligible Purchases.  All purchases of licenses for copies of
Programs, Technical Support, Support Services or other Services (except for
Software Development Services pursuant to Section 11.3 and any Additional
Services pursuant to Section 11.4), or any other products, materials, services
or information from GeoTel pursuant to this Agreement, whether by Licensee or
any Licensee Affiliate or Alliance Partner pursuant to Section 2.1 or credited
pursuant to Section 2.2B2 (collectively the "Eligible Purchases"), shall accrue
to the benefit of Licensee to fulfill the Purchase Commitment, including
without limitation all purchases of licenses for copies of Programs used for
demonstration, test or quality assurance purposes. All Eligible Purchases shall
be credited against the Purchase Commitment at the discounted price actually
paid to GeoTel for the Eligible Purchase.

        C.  Deficiency Payments/Excess Eligible Purchases.

            1.  GeoTel shall notify Licensee within fifteen (15) days after the
end of each of the three Contract Years as to any deficiency or excess between
the Purchase Commitment for such year and the value of the aggregate Eligible
Purchases actually made during such Contract Year (the "True-up Notice"),
failing the providing of such notice by GeoTel within such time frame as to any
deficiency, Licensee shall be deemed to have fulfilled its Purchase Commitment
for the Contract Year and shall have no further liability or obligation in
connection therewith. Provided that Licensee does not dispute any deficiency
contained in a True-up Notice, Licensee shall, within fifteen (15) days after
receipt of the notice, in fulfillment of the deficiency, either, at its sole
option: (i) pay the deficiency to GeoTel, or (ii) submit itself, and/or have
submitted by one or more Licensee Affiliates or Alliance Partners pursuant to
Section 2.1, to GeoTel one or more Orders for such aggregate quantity of
Eligible Purchases, along with any Installation Deposit required in connection
therewith pursuant to Section 6.1 B, as will be sufficient to fulfill the
deficiency (the "Deficiency Order(s)"). Licensee agrees that: (a) as to any
Program copies obtained pursuant to a Deficiency Order as to which Licensee
Designates to GeoTel an installation site prior to the thirtieth (30th) day
after Order Acceptance, acceptance of such copies shall be determined pursuant
to Article 7, or (b) as to Program copies as to which Licensee does not
designate to GeoTel an installation site by such thirtieth (30th) day from Order
Acceptance, such copies shall be deemed accepted for purposes of Article 7 as of
the ninetieth day after the end of the prior Contract Year, provided that at
such time as Licensee designates to GeoTel an installation site for any such
copy, GeoTel shall provide the required Installation Services at no additional
charge to Licensee. 

            2.  In the event that Licensee does not cure any deficiency for a
Contract Year as required pursuant to Section 2.4 C 1, and GeoTel claims a
breach of this Agreement but does not elect to terminate this Agreement, then
Licensee shall be obligated to pay to GeoTel in connection with such failure no
more than the difference between [ * ], and the value of all Eligible Purchases
made for the Contract Year as to which such deficiency applies. Notwithstanding
the foregoing sentence, in no event can the liability of Licensee pursuant to
this Section 2.4 C 2 exceed the limitation of liability set forth in Section
10.1 (ii). Upon any payment by Licensee pursuant to this Section 2.4 C 2,
Licensee shall be released from and have no further obligation or liability
whatsoever as to the Purchase Commitment for such Contract Year.

            3.  Any excess of the aggregate value of Eligible Purchases made
during a Contract Year over the Purchase Commitment shall be carried over and
applied against the Purchase Commitments in any subsequent Contract Years.

        E.  No Other Licensee Minimum Commitments.  Except to the extent
expressly set forth in this Section 2.4, Licensee does not otherwise guarantee
that any minimum quantity or dollar volume of Programs and/or Technical
Services, Support Services or other Services will be obtained by Licensee
and/or its Affiliates and Alliance Partners from GeoTel pursuant to this
Agreement or otherwise.

3.   PROGRAM LICENSES

     3.1  LICENSES GRANTED.

Licensee's certification lab for purposes of GeoTel obtaining and maintaining
during the Term certification from Licensee that all of the Programs, at the
then most Current Release level, and/or Update level being utilized by Licensee
during the Term, shall function in conformity with the Specifications when
operating and interacting with all Authorized Platforms and Licensee networks.

     3.2  TRANSFER.
          --------
 
          A.    GENERAL RIGHT TO TRANSFER LOCATION. Subject to Section 3.2 B, a
Program may be transferred to a different Designated Computer of like
configuration or the Designated Computer may be transferred to another location,

among Licensee and its Customers, and in any event without incurring any
additional license fee or other cost directly related to the transfer, provided
that in each case Licensee shall give timely written notice thereof to GeoTel,
and subject to Section 14.7, and provided further that Licensee shall remain
responsible for payment for any Support Services required in connection with any
such transfer.

          B.    TRANSFER AFTER TERMINATION OF AGREEMENT. Notwithstanding the
provisions of Section 3.2A, during a period of three (3) years from the

          C.    RIGHT TO TRANSFER PROGRAM COPIES TO CUSTOMERS. As to each copy
of a Program licensed by Licensee hereunder, from and after the date five (5)
years from the date of receipt from GeoTel of the Installation Certificate for
the initial version of such copy obtained by Licensee hereunder, Licensee
shall be entitled to transfer the most recent Update or Release for such copy
to any then-existing Licensee Customer ("Transferee Customer") who has been
supported by that copy and/or its replacement Updates and Releases for a
minimum continuous period of five (5) years, and GeoTel shall grant an end-user
license to the Transferee Customer as to such most recent Update or Release
copy, provided that: (i) such Transferee Customer executes as to such copy
GeoTel's then current agreement for end-user licensing for use in providing
internal services or such other terms and conditions as may be mutually agreed
by GeoTel and the Transferee Customer; (ii) if the copy being transferred is
not then subject to Technical Support, the Transferee Customer pays all fees
required to bring such copy to the then-current revision level; (iii) the
Transferee Customer pays for all Services which it obtains, in its sole
discretion, from GeoTel in connection with such transfer; and (iv) no
additional fee shall be charged to the Transferee Customer for such transfer
except that where the Program copy being transferred was being used on a
partitioned Intelligent Call Router that supported multiple Customers,
including the Transferee Customer, then the Transferee Customer shall pay any
additional fee as may be negotiated between the Transferee Customer and GeoTel.
From and after the effective date of transfer of any copy of a Program to a
Transferee Customer, Licensee's license hereunder as to such copy shall be
deemed terminated and Licensee shall have no further obligation or liability
whatsoever in connection with such copy or the terminated license, all
liability thereafter as to such copy being that of the Transferee Customer.

          D.    NO OTHER TRANSFER OR ASSIGNMENT OF COPIES. Except as otherwise
provided in this Article 3 and Section 14.5, the rights granted herein as to
Program copies are restricted for use solely by Licensee and may not be assigned
or transferred to a third party.

4.   TERM; TERMINATION

     4.1  TERM. This Agreement shall have an initial term of three (3) years 
from the Effective Date (the "Initial Term") after which Initial Term this
Agreement shall automatically renew for consecutive one (1) year periods
("Extension Periods") based upon the terms and conditions then contained in this
Agreement (other than the provisions of Section 2.4 regarding the Purchase
Commitment which shall not be automatically renewed), unless either Party
provides written notice to the other no later than ninety (90) days prior to the
end of the Initial Term or the then-current Extension Period of its intent to
terminate this Agreement in which event this Agreement shall terminate as of the
end of such Initial Term or Extension Period, as applicable. The Initial Term
and any Extension Periods may be collectively referred to in this Agreement as
the "Term".

     4.2  TERMINATION OF AGREEMENT. Upon thirty (30) days' prior written notice,
either Party may terminate this Agreement in the event:

             (i) that the other Party breaches any of its material obligations 
hereunder and fails to cure such breach by the end of such thirty-day period; or

             (ii) of either Party's application for or consent to the

case under the Federal Bankruptcy Code (as now or hereinafter in effect); its
failure to contest in a timely or appropriate manner, or its acquiescence in
writing to, any petition filed against it in an involuntary case under such
Bankruptcy Code, or its liquidation, reorganization or dissolution;

provided, however, that GeoTel agrees that any termination by GeoTel of this
Agreement shall not affect any licenses for Programs previously granted to
Licensee hereunder pursuant to Article 3 unless the underlying breach of this
Agreement provides a separate basis for termination of one or more such licenses
pursuant to Section 4.3 below.

obligations pursuant to Sections 3.1,5.3, 8.1 or 8.2 specifically as to such
copy and Licensee fails to cure such breach by the end of such thirty-day
period; provided, however, that GeoTel agrees that any termination by GeoTel of
the license to


<PAGE>   11

for termination of either (i) any other license to a Program copy as to which
such breach does not specifically apply or (ii) this Agreement pursuant to
Section 4.2.

          B.    TERMINATION BY LICENSEE. Licensee may terminate a license to a 
copy of a Program granted to License hereunder as provided in Sections 7.2 and

granted hereunder shall not limit either party from pursuing any other remedies
available to it, including injunctive relief.

termination of this Agreement shall serve to terminate, modify or otherwise
affect any licenses for Programs granted to Licensee hereunder, all of which
licenses shall remain in full force and effect after any such termination or
expiration.




<PAGE>   12



          C.    Purchase Commitment.  As to any termination of this Agreement:

any resulting failure to fulfill Licensee's obligations pursuant to Section 2.4
no more than the difference between  * , and the value of all Eligible Purchases

shall be released from and have no further obligation or liability whatsoever

Contract Year, the Purchase Commitment for the then-current Contract Year and
any Purchase Commitment for any subsequent Contract Years.


     4.5  RETURN OF PROGRAM UPON TERMINATION. If this Agreement or a license as

otherwise terminated, each Party shall as to this Agreement or such license, as
applicable: (i) pay to the other Party any related moneys then due and owing,

such Program that will be in effect as of said anniversary date. Should GeoTel
at any time make any of the Programs or Services generally commercially
available at a lower price than as then listed in Exhibit C prior to application
of any available discount, then the Exhibit C pricing shall be reduced
accordingly retroactive to the effective date of such lower generally
commercially available prices.

     5.2  MOST FAVORED CUSTOMER. GeoTel agrees that the prices charged, and
discounts available, hereunder from time to time for license(s) for the
Programs, or for Technical Support, Support Services or any other materials or

the prices charged, and discounts made available, to any other customer of
GeoTel for substantially similar volumes of such licenses, services or other
materials under


* Portions have been omitted for confidential treatment.

the completion of the applicable Service and the invoices will then be due and
payable net forty five (45) days from receipt of invoice by Licensee's Vendor
Services Department; provided, however, that invoices for Technical Support will
be forwarded to Licensee after commencement of the applicable month of Technical
Support and the invoices will then be due and payable net forty five (45) days
from receipt of invoice by Licensee's Vendor Services Department.

<PAGE>   16



in accordance with such other test and acceptance criteria as may be mutually
agreed by the Parties in writing, provided that failure of Licensee to accept or
reject a Program copy within the applicable Acceptance Period shall be deemed

GeoTel shall have fifteen (15) days from receipt of notice of rejection to
correct the Errors or other nonconformity's at no additional cost to Licensee

thirty (30) days from Licensee's receipt of the corrected copy of the Program to
accept or reject the Program as provided above (the "Additional Acceptance
Period"). Should GeoTel either be unable to correct the Errors or other
nonconformity's within such Correction Period or should Licensee again reject
the corrected Program during the Additional Acceptance Period, then Licensee, at
its sole option, shall be entitled to either:

          (i) a full refund of any payments made to GeoTel, including but not 
limited to any related Installation Deposit, Support Services or other Services,
in connection with the rejected copy, provided, that (x) the full value of the
Eligible Purchases as to which the refunds applied as determined pursuant to
Section 2.4 B shall nonetheless continue to be credited against any applicable
Purchase Commitment, and (y) as of the second time within any rolling sixth
month period that Licensee rejects any Program copy after the Additional

immediately terminate this Agreement by written notice to GeoTel pursuant to
said Section 4.2; or

acceptable to, and at no additional cost to, Licensee.

     7.3  ABATEMENT OF PAYMENT. Licensee's obligation to pay an invoice issued

pursuant to Section 7.1 shall be abated during the Correction Period and
Additional Acceptance Period provided pursuant to Section 7.2.

any part thereof except to the extent otherwise expressly permitted by this

                (iii) not to disclose any such Confidential Information to any 
third party using the same degree of care used to protect the confidential or
proprietary information of like importance of the receiving Party ("Recipient"),
but in any case using no less than a reasonable degree of care; provided,
however, that Recipient may disclose Confidential Information received hereunder
to (x) its Affiliates who are bound to protect the received Confidential
Information from unauthorized use and disclosure under the terms of a written
agreement, and (y) to its employees, consultants and agents, and its Affiliates'
employees, consultants and agents, who have a need to know to perform or
exercise rights under this Agreement, and who are bound to protect the received
Confidential Information from unauthorized use and disclosure under the terms of
a written agreement. GeoTel expressly agrees that Licensee shall further be
entitled to disclose the Confidential Information of GeoTel received hereunder
to Customers and prospective Customers and their respective employees,
consultants and agents who have a need to know in connection with the exercise
of the rights set forth in Section 3.1 above or otherwise in connection with use
or the prospective use of Licensee services and products based on use of the
Programs. Confidential Information shall not otherwise be disclosed to any
person without the prior written consent of the Discloser; and

                (iv) to return or destroy such Confidential Information and any
copies thereof upon the expiration or earlier termination of this Agreement, or
Program license, as applicable, to the extent, and as required pursuant to,
Section 4.5.

thereof to Recipient;


<PAGE>   18



                (ii) becomes publicly known through no fault of Recipient 
subsequent to the time of Discloser's communication thereof to Recipient;

                (iii) is in Recipient's possession free of any obligation of 
confidence at the time of Discloser's communication thereof to Recipient;

                (iv) is developed by Recipient independently of and without use
of any of Discloser's Confidential Information or other information that
Discloser disclosed in confidence to any third party;

                (v) is rightfully obtained by Recipient from third parties 
authorized to make such disclosure without restriction; or

                (vi) is identified by Discloser in writing as no longer 
proprietary or confidential.

          D.    DISCLOSURE PER ORDER. In the event Recipient is required by law,
regulation or court order to disclose any of Discloser's Confidential
Information, Recipient will promptly notify Discloser in writing prior to making
any such disclosure in order to facilitate Discloser seeking a protective order
or other appropriate remedy from the proper authority. Recipient agrees to
cooperate with Discloser in seeking such order or other remedy. Recipient
further agrees that if Discloser is not successful in precluding the requesting
legal body from requiring the disclosure of the Confidential Information, it
will furnish only that portion of the Confidential Information which is legally
required and will exercise all reasonable efforts to obtain reliable assurances
that confidential treatment will be accorded the Confidential Information.

          E.    PUBLICITY. No news, media or other informational releases, 
public announcements, public disclosures, advertising or marketing materials 
concerning any part or terms and conditions of this Agreement or any of GeoTel's
or Licensee's respective performances hereunder shall be made, issued or
distributed by either Party without the prior written consent of the other
Party, which consent shall not be unreasonably withheld or delayed.

          F.    SURVIVAL. The provisions of this Article 8 shall survive for a
period of five (5) years beyond the effective date of any expiration or earlier
termination of this Agreement.

     8.2  OWNERSHIP OF PROGRAMS.
          ----------------------

          A.    Licensee acknowledges that GeoTel claims that: (i) GeoTel is 
the owner of the Programs and any copies thereof, and of all copyright, trade
secret, patent, trademark, or other intellectual property rights therein, and
(ii) the ideas and the expressions thereof contained in the Programs are the
confidential and proprietary information and trade secrets of GeoTel.

          B.    Licensee agrees that physical copies of the Programs, in
firmware, diskette, tape, paper, or other form provided by GeoTel shall remain
the property of GeoTel, and such copies shall be deemed to be on loan to
Licensee during the term of the licenses granted pursuant to this Agreement.

          C.    Licensee agrees that it will not decompile, disassemble or 
attempt in any way to reverse engineer the Programs.

     8.3  ENFORCEMENT. Each Party acknowledges that the Confidential Information
of the other Party, including without limitation the Programs and User
Documentation, is valuable and unique to such Party and that disclosure, use or
treatment of the same in breach of the provisions of this Article 8, will result
in irreparable injury to the disclosing Party for which monetary damages alone
would not be an adequate remedy. Therefore, each Party agrees that, in the event
of a breach or threatened breach of the confidentiality or restricted use
provisions of this Article 8 by the other Party, the disclosing Party shall be
entitled to seek specific performance and injunctive or other equitable relief
from a court of competent jurisdiction as a remedy for any such breach or
anticipated breach, and the disclosing Party shall further have no obligation to
post bond or other surety in connection therewith. Any such relief shall be in
addition to and not in lieu of any appropriate available relief in the way of
monetary damages and shall not otherwise limit such Party's other available
rights and remedies.

9.   INDEMNITY RE INFRINGEMENT; WARRANTIES;  DISCLAIMERS

     9.1  WARRANTY OF OWNERSHIP; INDEMNITY RE INFRINGEMENT.
          -------------------------------------------------

          A.    GeoTel warrants and represents that it is the sole owner of all
patent, copyright, trade secret, trademark and other intellectual property
rights in the Programs and User Documentation or, if the Programs or User
Documentation contains third party software or other materials, GeoTel has the
unrestricted right to grant to Licensee all of the licenses and other rights
necessary for complying with this Agreement, and in any event has the full power
and authority to sell, convey, license, and deliver copies of the Programs and
User Documentation free from any liens and encumbrances of all kinds.

          B.    GeoTel shall at its expense defend or, at its option, settle, 
any claim, action or proceeding brought against Licensee and/or any Customer
that any Program, the User Documentation or any services provided by Licensee
and/or any Customer based on the use of the Programs, or the use of any of the
foregoing, infringes a patent, copyright, trade secret,


<PAGE>   20



trademark or other intellectual property right, and shall indemnify and hold
Licensee and its Customers harmless against all losses, damages, liabilities,
expenses and costs incurred and/or awarded against or by Licensee and/or any
Customers in connection with any such claim, action or proceeding. Licensee
shall: (i) notify GeoTel in writing of any such claim promptly after Licensee
becomes aware of the same, (ii) give GeoTel such information and assistance as
reasonably required in connection therewith but at the expense of GeoTel, and
(iii) give GeoTel sole control of the defense of such claim and all negotiations
for the compromise or settlement thereof; provided, however, that the failure of
Licensee to undertake any of the foregoing actions shall not relieve GeoTel of
any liability or obligation it may have under this Section 9.1 except to the
extent that GeoTel has been adversely affected thereby. Notwithstanding Subitem
(iii) in the preceding sentence:

                (i) Licensee shall have the right to participate in the 
investigation and defense of any such claim, action or proceeding, with separate
counsel chosen and paid for by Licensee; and

                (ii) at any time, Licensee may at its own cost and expense 
purchase intellectual property or rights thereto from any third party.

          C.    Without limiting the rights of Licensee pursuant to Section 
9.1 F, if the use of any Program, the User Documentation or any service based on
the use of the Programs or User Documentation or any part thereof, is enjoined
in connection with a claim of infringement of any patent, copyright, trade
secret right or other intellectual property right, GeoTel shall, at its sole
expense, take the following actions listed in the order of requirement (but in
no event shall GeoTel be relieved of any obligations of defense and indemnity
hereunder):

                (i) obtain for Licensee a license permitting the continued use
of the Program, User Documentation and/or service or such part thereof pursuant
to the terms of this Agreement;

                (ii) replace or modify the affected Program, user Documentation
or part thereof, so that it becomes non-infringing, while still complying with
the applicable Specifications and other requirements of this Agreement; or

                (iii) if neither of the foregoing can be accomplished without 
impacting the economic viability of GeoTel, terminate the license for the
affected Program(s) or User Documentation and promptly refund to Licensee: (x)
the license or other fees paid for the same under this Agreement amortized over
a seven (7) year period commencing as of the Commencement Date for the
applicable Program, and (y) the pro-rated unused portion of any Technical
Support fees paid in connection with the same; provided, however, that the full
value of the Eligible Purchases as to which any refunds pursuant to Subitems (x)
and (y) of this sentence relate, as determined pursuant to Section 2.4 B, shall
nonetheless continue to be deemed "Eligible Purchases" and credited against any
applicable Purchase Commitment pursuant to Section 2.4 C.


<PAGE>   21



          D.    GeoTel shall have no liability under Section 9.1B for any costs
of defense incurred, or settlement entered into, by Licensee as to an
indemnifiable claim hereunder without GeoTel's prior written consent.

          E.    GeoTel shall have no liability under this Section 9.1 to the 
extent that any claim of infringement is based upon (i) the combination of a
Program with other products, equipment or materials that are either not
furnished or approved by GeoTel, not an Authorized Platform, or where GeoTel
should not reasonably have anticipated such combined use, and provided that in
any event the claim of infringement would not have occurred but for such
combination, (ii) any addition to or modification to the Program, including
without limitation to any new Release of the Program, by any person or entity
other than GeoTel made without GeoTel's consent or concurrence, if such claim of
infringement would not have occurred but for such addition or modification,
(iii) GeoTel furnishing to Licensee any information, data, service or
applications assistance, other than the Services, Programs and the related User
Documentation, if the claim of infringement would not have occurred but for such
information, data, service or applications assistance, or (iv) use of a
superseded Release of the Program beyond the time frame specified in Section
11.1D, provided that a replacement Release has been made available to Licensee
within such timeframe specified in Section 11.1D, that such replacement Release
still complies with the applicable Specifications, and that the claim of
infringement would not have occurred but for Licensee continuing to use such
superseded Release of the Program as opposed to the replacement Release.

          F.    Upon the receipt by Licensee or any Customer within a Contract
Year of either notice by or on behalf of a third party alleging or asserting any
claims of infringement within the scope of this Section 9.1, service upon
Licensee or any Customer of any legal action or other proceeding instituted by
or on behalf of a third party alleging in whole or in part an infringement
within the scope of this Section 9.1, or the imposition of a temporary
restraining order, or temporary or permanent injunction on Licensee or any
Customer based in whole or in part upon a claim by or on behalf of a third party
of infringement within the scope of this Section 9.1, then, in addition to, and
without limiting any of the other obligations of GeoTel pursuant to this Section
9.1 in connection with any of the foregoing, the Purchase Commitment shall from
the date of receipt of such notice, service of process, or imposition as to
Licensee or any Customer, be waived, and Licensee shall be released from and
have no further obligation or liability in connection therewith, on a day to
day, pro rata basis until such time as such claim, action or other proceeding is
finally resolved, or such temporary restraining order, or temporary or permanent
injunction is finally lifted or dissolved, as applicable, provided that from and
after the ninetieth day without such final resolution, Licensee shall be
entitled, at its option, to then or at any time while such situation continues
unresolved, to treat such failure to resolve any of such events as a material
breach of this Agreement pursuant to Section 4.2 (but without the further right
of GeoTel to cure as otherwise set forth therein), and to immediately terminate
this Agreement by written notice to GeoTel pursuant to said Section 4.2.

          G.    THE PROVISIONS OF THIS SECTION 9.1 STATE THE EXCLUSIVE LIABILITY
OF GEOTEL, AND THE EXCLUSIVE REMEDY OF LICENSEE, WITH RESPECT TO ANY BREACH OF
THE WARRANTY SET FORTH IN SECTION 9.1 A OR


<PAGE>   22



ANY CLAIM OF INFRINGEMENT OF ANY PATENT, COPYRIGHT, TRADE SECRET, TRADEMARK OR
OTHER INTELLECTUAL PROPERTY RIGHT BY THE PROGRAMS, THE USER DOCUMENTATION, OR
ANY SERVICES PROVIDED BY LICENSEE AND/OR ANY CUSTOMER BASED ON THE USE OF THE
PROGRAMS, OR THE USE OF ANY OF THE FOREGOING.

shall provide sufficient evidence to demonstrate adequate testing of the
Programs to meet this requirement;

                (ii) it has full power and authority to enter into and perform
this Agreement, and the person signing this Agreement on behalf of GeoTel has
been properly authorized and empowered to enter into this Agreement;

                (iii) disputes over specific named Programs or copies thereof 
will not interfere with Technical Support or any other Services for Programs or
copies thereof separately licensed and paid for by Licensee;

                (iv) no material portion of the Programs is or will be intended,
other than under documented control of Licensee:

                    (x) at some specific time or on a specific instruction or 
occurrence of a given event, to stop, limit or interfere with the operation of
the Programs in conformity with the applicable Specifications, or;

                    (y) to damage or materially alter or render inaccessible the
Programs, or any other hardware, software or data which the Programs are
designed to process or use, or any other hardware, programs or data attached to,
resident on, or accessible to the system on which the Programs are executed or
stored; and

GeoTel shall be responsible for, indemnify and hold Licensee harmless from any
damages, costs, liabilities, and/or expenses, including attorneys' fees and
other legal costs, arising out of the breach of the foregoing Subitems (x) and

                (vi) the Programs, at the then most Current Release level 
and/or Update level being utilized by Licensee during the Term, shall at all
times function in conformity with the Specifications when operating and
interacting with all Authorized Platforms and Licensee networks, provided,
however, that where Licensee makes a change in the RDG, then this warranty shall
be abated for a period of ninety (90) days commencing with the effective date of
such change and, subject to Licensee fulfilling its obligation pursuant to
Section 3.1 E, commencing with the ninety first (91st) day from the effective
date of the change to the RDG this warranty shall once again be in full force
and effect as to GeoTel, the Parties expressly agreeing that the foregoing
warranty is intended as a warranty separate from that set forth in Section 9.2
B;

                (vii) during the Term, the Programs, at the then most current
Update level and then most Current Release level, will remain competitive with
respect to software made available by other vendors of call routing software;

                (viii) it may lawfully grant the licenses for the Programs;

                (ix) as of the Effective Date the Deposit Agreement between 
GeoTel and Data Securities International, Inc. dated August 25, 1995, in the
form attached hereto as Exhibit G for information purposes only (the "Deposit
Agreement"), is in full force and effect; and

                (x) as of the Effective Date, full and complete copies of 
GeoTel's then-current Source Code for all of the Programs either then being

subject to, the Deposit Agreement.

          B.    ADDITIONAL PROGRAM LICENSE WARRANTIES. GeoTel warrants and 
represents that for a period of ninety (90) days following the acceptance of a
copy of any Program by Licensee pursuant to Article 7 (the "Warranty Period"),
the copy will be free of Errors when operated on the Authorized Platforms for
such Program. Without limiting any rights or remedies that Licensee may have for
GeoTel's breach of any other warranties set forth in this Section 9.2, in the
event of breach of the foregoing warranty GeoTel shall correct the Error(s)
pursuant to the requirements of Section 11.1 at no additional cost to Licensee,
including without limitation payment to Licensee of Liquidated Damages as
defined and provided in Section 11.1 B 2. Should GeoTel fail to resolve a
Critical Situation in a copy of a Program, as required by Section 11.1 B 1 (i),
by the tenth (10th) day after receipt of notification of the same from Licensee
during the applicable Warranty Period, Licensee can elect, in its sole
discretion either to:

                (i) continue to receive such Liquidated Damages until the 
Critical Situation is so resolved; or

                (ii) at any time from and after the twentieth (20th) day while 
such Critical Situation remains unresolved, elect to immediately terminate the
license for such copy and GeoTel shall immediately refund to Licensee all
license fees plus any other moneys paid to GeoTel in


<PAGE>   24



connection with such copy, including but not limited to any fees paid for
Technical Support, Installation Services (including such fees paid as an
Installation Deposit) or other Services in connection therewith, provided,
however, that (x) the full value as determined pursuant to Section 2.4 B of the
Eligible Purchases as to which any refunds pursuant to this Subitem (ii) relate,
including without limitation the terminated license for the Program copy and any
related Services, shall nonetheless continue to be deemed Eligible Purchases and
credited against any applicable Purchase Commitment pursuant to Section 2.4 C,
and (y) as of the second instance within any rolling six (6) month period that
Licensee terminates any license to a copy of a Program pursuant to this Subitem
(ii), Licensee shall further be entitled at its option, and in addition to such
rights of termination, refund and continued crediting against the Purchase
Commitment, to treat such second failure to resolve a Critical Situation as a
material breach of this Agreement pursuant to Section 4.2 (but without the
further right of GeoTel to cure as otherwise set forth therein), and to
immediately terminate this Agreement by written notice to GeoTel pursuant to
said Section 4.2.

          C.    MEDIA WARRANTY. GeoTel warrants the tapes, diskettes or other

<PAGE>   25



     9.3  OTHER LIMITATIONS ON WARRANTIES.
          --------------------------------

          A.    No employee or agent of GeoTel is authorized to give a greater 
or different warranty than those set forth herein, unless provided by way of an
amendment to this Agreement pursuant to Section 14.11.

          B.    Portions of the Programs are derived from third-party software
licensed to GeoTel for integration into GeoTel Programs and sublicensing. No
such third party warrants the Programs or any such portion, assumes any
liability regarding use of such portion or the Programs, or undertakes to
furnish any support or information relating to such portion or the Programs,
provided that the foregoing shall not in any manner limit the applicability of
any obligations as to the Programs undertaken by GeoTel pursuant to this
Agreement as to the Programs in their entirety.

          C.    DISCLAIMERS. THE EXPRESS WARRANTIES SET FORTH IN SECTION 9.1 
AND 9.2 ARE THE ONLY WARRANTIES MADE BY GEOTEL WITH RESPECT TO THE PROGRAMS,
SUPPORT SERVICES AND TECHNICAL SUPPORT. GEOTEL MAKES NO OTHER WARRANTIES,
EXPRESS, IMPLIED OR ARISING BY CUSTOM OR TRADE USAGE, AND SPECIFICALLY MAKES NO
WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.

10.  LIMITATION OF LIABILITY

     10.1 LIMITATIONS.  The limitations of liability set forth in this Section
10.1 shall not apply to GeoTel's obligations pursuant to Sections 9.1,
9.2 A.(iv) and 11.8. Except as to any breaches by either Party of the provisions
of Article 8 as to which only the limitation of liability set forth in Section
10.1(ii) shall apply:

          (i)   in no event shall GeoTel or its licensors,or Licensee or its
Customers be liable for any special, incidental, indirect, exemplary, punitive
or consequential damages, or for any lost profits, use, data, business or
revenue, or other lost economic advantage, arising out of or relating to this
Agreement, including without limitation in connection with the performance of
the Programs, Support Services, Technical Support, or any other obligations
relating to this Agreement, whether such claims or asserted damages are based
on breach of contract, strict liability, tort, any federal or state statutory
claim, or any other legal theory, and even if the other Party knew, should have
known, or has been advised of the possibility of such damages; and

          (ii)  in no event shall either Party's aggregate, cumulative
liability to the other Party in connection with all breaches of this Agreement,
including any breaches of Article 8, as well as any liability of Licensee
pursuant to Section 2.4 C 2 and Section 4.4 C(i), exceed in the aggregate the 
net moneys for Program copy licenses and Services (other than Software
Development Services) paid by Licensee from the Effective Date through the date
of the latest breach of this Agreement, but in any event such aggregate,
cumulative liability cap shall not be less than * subject to the following:

                (x)     in any event, the maximum aggregate, cumulative
recovery established pursuant to this Subitem (ii) available to a Party shall be
net of any and all sums paid by the other Party for any prior breaches of this
Agreement, and as to GeoTel only, net as well of any payments of Licensee
pursuant to Section 2.4 C 2 and Section 4.4 C(i);

                (y)     the Parties expressly acknowledge and agree that the
foregoing limitation is intended to apply, and shall apply, cumulatively and in
the aggregate to all breaches of this Agreement, and as to Licensee any
liability of Licensee pursuant to Section 2.4 C 2 and Section 4.4 C(i),
falling within the scope of this Subitem (ii) and not separately to each such
breach or as to Licensee, any such liability, and

                (z)     such aggregate, cumulative limitation shall apply
whether any damages or other liability are (i) characterized as compensatory,
direct, special, incidental, indirect, exemplary, punitive, consequential
damages or otherwise, including without limitation as lost profits, use, data,
business or revenue, or other lost economic advantage, or (ii) asserted under
a theory of breach of contract, strict liability, tort, any federal or state
statutory basis, or any other legal theory or basis, and even if the other Party
knew, should have known, or has been advised of the possibility of such damages.


     10.2 MORE FAVORABLE LIMITATIONS. GeoTel agrees that the foregoing
limitations of liability, both separately and in the aggregate, afforded to
Licensee hereunder shall from time to time and at all times during the Term, be
no less favorable than any limitations of liability, offered to, or agreed to,
by GeoTel with any third party. Where GeoTel offers, or agrees to, any such more
favorable limitation(s) of liability with a third party, GeoTel shall
immediately notify Licensee in writing of the same, such more favorable
limitation(s) shall apply retroactively to Licensee from the date that the same
were offered, or otherwise agreed to, and the Parties shall promptly amend this
Agreement accordingly.

     10.3 ALLOCATION OF RISKS. The provisions of this Article 10 allocate the
risks under this Agreement between GeoTel and Licensee. GeoTel's pricing
reflects this allocation of risk and the limitations of liability specified
herein.

11.  SERVICES

     11.1. TECHNICAL SUPPORT SERVICES.
           ---------------------------

          A.    During the applicable Warranty Period, GeoTel will provide 
Licensee for each copy of the Programs obtained by License hereunder without
additional charge the technical






*Portions have been omitted for Confidential Treatment
<PAGE>   26



support as specified in this Section 11.1 and Section 4 of Exhibit D
("collectively the "Technical Support"), provided, that in the event of conflict
between the terms and conditions of this Section 11.1 and those of said Section
4 of Exhibit D, the terms and conditions of this Section 11.1 shall prevail.
Thereafter, during the Term and after any expiration or earlier termination of
this Agreement during such period as Licensee desires to continue, or obtain,
the same as to each such copy, Licensee shall be entitled to purchase Technical
Support, in its sole discretion, and GeoTel shall be obligated to provide such
Technical Support, upon payment by Licensee pursuant to Article 5 of the
applicable Technical Support fee as determined pursuant to Exhibit C, provided
that where Licensee elects to purchase Technical Support after the expiration or
termination of this Agreement, the applicable Technical Support fee shall be
determined based on Exhibit C as in effect as of the effective date of such
expiration or termination.

          B.    1. Upon receipt of notice(s) from Licensee specifying Errors in
the current unaltered Release of the Program copy, and upon receipt of such
additional information as GeoTel may reasonably request, GeoTel will, without
cost to Licensee, resolve situations involving Errors according to the following
Severity Levels as assigned to such Errors by Licensee, provided such notice is
received by GeoTel within the Warranty Period or during the term of the
Technical Support, as the case may be:

                (i) CRITICAL SITUATIONS: A "Critical Situation" is defined as a
situation in which an Error materially impacts Licensee's and/or a Customer's
productivity and/or service levels. Upon receipt of notification of a Critical
Situation by the GeoTel support organization, GeoTel will work with Licensee
and/or the Customer on a continuous, 24 hour per-day basis, and resolve the
Critical Situation within five (5) calendar days from such notification. GeoTel
can respond to a Critical Situation through providing an Update, patch, revision
or temporary workaround solution or by replacing the affected Program copy with
a Program copy conforming to the Specifications, and GeoTel shall be deemed to
have "resolved" a Critical Situation if it has either corrected the Error(s) or
moved Licensee and the Customer to either a "Moderate" or "Other Situation"
status, as defined below.

                (ii) MODERATE SITUATIONS: A "Moderate Situation" is defined as 
a situation in which Licensee's and/or Customer's operations are continuing but
the Error impairs the ability to use one or more functions of, or the
performance of, services based on the Program copy. GeoTel will respond to, and
resolve the Moderate Situation by providing to Licensee an Update, patch,
revision or temporary workaround or by replacing the affected Program copy with
a Program copy conforming to the Specifications and in any event correcting the
Error within fourteen (14) days after receiving notice from Licensee of the
situation.

                (iii) OTHER SITUATIONS: In all other instances, GeoTel will
provide a solution to a reported GeoTel Program Error in the time frame
reasonably determined by GeoTel.

Where the resolution provided by GeoTel to either a Moderate Situation, or a
Critical Situation that has been reduced to a Moderate Situation, is not
permanent, then GeoTel shall provide a


<PAGE>   27



permanent solution as a part of the next Update or Release.

                2. The Parties agree that it would be difficult to ascertain the
damages which might be incurred by Licensee as the result of the failure of
GeoTel to resolve a Critical Situation in a copy of a Program as required
pursuant to Section 11.1 B.1(i). Therefore, GeoTel acknowledges and agrees that
for each Error giving rise to a Critical Situation as to a copy of a Program
which GeoTel fails to resolve in the manner specified in Section 11.1 B.1(i)
within the required five days from receipt of notification from Licensee of the
Critical Situation as to such copy, GeoTel shall be liable to Licensee by way of
liquidated damages, and not by way of a penalty, for the amount of REDACTED
MATERIAL per day for each day in excess of such five day maximum that GeoTel
fails to resolve each such Error (the "Liquidated Damages"). Any such Liquidated
Damages shall be paid by GeoTel to Licensee, in Licensee's sole discretion, by
way of either: (i) a payment or payments to be made by GeoTel to Licensee at
such intervals during the continuation of any such failure to correct such
Errors as determined in Licensee's sole discretion, or (ii) one or more offsets
against any then outstanding or subsequent invoices submitted by GeoTel to
Licensee under this Agreement, again as determined in Licensee's sole
discretion, until all Liquidated Damages incurred pursuant to this Section are
paid by GeoTel in full, or (iii) a combination of the foregoing methods of
payment until all such Liquidated Damages are paid in full.

          C.    RESTRICTIONS ON PROVIDING ERROR CORRECTIONS. GeoTel is not 
obligated to perform investigation and/or corrections of Errors reasonably found
by GeoTel to be either: (i) in other than a current, unaltered Release, provided
that GeoTel has made a current Release available to Licensee within the
timeframe specified in Section 11.1D and such new Release still complies with
the applicable Specifications; (ii) caused by Licensee's negligence; (iii)
caused by a modification to the Program by any person or entity other than
GeoTel made without GeoTel's consent or concurrence; (iv) use of the Program in
combination with programs either not furnished or approved by GeoTel or
otherwise certified by GeoTel as working in combination with such Program, or
the use of which in such combination should not reasonably have been anticipated
by GeoTel; (v) caused by use of the Program outside the scope of the User
Documentation; or (vi) due to external causes such as, but not limited to, power
failure or electric surges.

          D.    UPDATES AND RELEASES. Promptly after making the same generally
commercially available or otherwise available to its other licensees of the
Programs, GeoTel will provide Licensee with one (1) complete copy of each new
Release or Update and one (1) copy of the corresponding User Documentation for
each copy of the Program licensed by Licensee and covered by the Update or
Release. Following shipment of the Release materials, the previous Release shall
remain "current" for purposes hereof for a period of one hundred eighty (180)
days; thereafter only the newly delivered Release will be current. Such newly
delivered Release and the immediately prior Release for such period of 180 days

          E.    RENEWAL/TERMINATION OF TECHNICAL SUPPORT. Each initial term of
Technical Support shall be for a period of one (1) year from the day after the
date of expiration of the Warranty Period and shall automatically renew for
additional, consecutive one-year terms pursuant to the terms and conditions of
this Section 11.1 unless, not less than thirty (30) days prior to the date upon
which the then-current term is due to end, Licensee notifies GeoTel in writing
of its intention to terminate Technical Support in which event Technical Support
shall terminate as of the end of the then-current term of Technical Support. In
addition, Licensee shall be entitled to terminate Technical Support at any time
for a Program copy on thirty (30) days prior written notice to GeoTel, in which
event Licensee shall receive a prorated refund, on a per diem basis, of any
remaining balance of Technical Support fees paid.

          F.    PRORATED STARTING DATE. GeoTel will prorate Technical Support 
fees so that Technical Support for all Programs on a single Designated Computer
or in a single local area network are renewable on the same date, even if all
the Programs or Technical Support were not ordered at the same time. When GeoTel
and Licensee jointly designate such a common renewal date, then renewal and/or
termination pursuant to Section 11.1.E shall take place with reference to that
date.

          G.    REINSTATEMENT OF TECHNICAL SUPPORT. Licensee may reinstate 
Technical Support which has been terminated by payment of a "Reinstatement Fee"
equal to the Technical Support fees that would otherwise have been applicable
pursuant to Exhibit C to the period between the effective date of termination of
Technical Support and the effective date of reinstatement plus payment of the
annual Technical Support fee for the one year period commencing upon the
effective date of reinstatement.

          B.    Training Services.
                ------------------

                1. During the Term, Licensee shall be entitled, in its sole 
discretion, to purchase Training Services, in addition to those otherwise
included as part of Installation Services, as described in this Section 11.2 B
and Section 3 of Exhibit D (provided that in the event of conflict between the

                2. GeoTel and Licensee may agree to a "Train the Trainer" 
program whereby GeoTel will provide in-depth training services to individuals
designated by Licensee as "Trainers". These "Trainers" will then develop
training materials, documentation and curricula, at Licensee's sole cost, to
support a training program in which Licensee's employees or contractors may
participate to become trained in the use and/or operation of the Programs. The
charge, if any, to Licensee for each such "Trainer" to attend GeoTel training

     11.3 SOFTWARE DEVELOPMENT SERVICES
          -----------------------------

          A.    During the Term, GeoTel shall develop and provide to Licensee 
such modifications to the GeoTel Software (the "Modifications") as may be
requested from time to time by Licensee (the "Software Development Services"),
subject to GeoTel notifying Licensee in


<PAGE>   30



writing within thirty (30) days after receipt of each such request as to a
reasonable, good faith basis upon which GeoTel believes that the development of
the requested Modifications are either (i) not technically feasible, or (ii)
inconsistent with GeoTel's core business. Such notice shall set forth in
reasonably sufficient detail the basis for GeoTel's rejection.

          B.    Unless GeoTel provides the foregoing notice to Licensee within
the applicable thirty day time period, GeoTel shall work with Licensee to create
a requirements document for the requested Modifications (the "Technical
Specification"), which Technical Specifications are subject to the final
approval of Licensee. Licensee shall reimburse GeoTel for the reasonable time
and materials costs incurred by GeoTel in developing the Technical
Specifications by either: (i) reimbursing GeoTel for such costs promptly after
the Parties have failed to agree upon the development terms and conditions for
the Modifications required pursuant to Section 11.3 C within a reasonable period
of time after finalization of the Technical Specifications, or (ii) where such
terms and conditions are agreed upon by the Parties within such reasonable time
period, then such time and materials costs shall be incorporated into the agreed
pricing for the development of the Modifications. The rates for GeoTel personnel
developing the Technical Specifications shall be those set forth in Section C of
Exhibit C.

          C.    Upon finalization of the applicable Technical Specifications,
GeoTel and Licensee shall negotiate, in good faith, the terms and conditions
governing development by GeoTel of the requested Modifications pursuant to the
Technical Specifications, including without limitation: (i) the applicable
development milestones/deliverables and schedule, (ii) the payment mode, whether
by fixed price, hourly or otherwise, but subject to Section 11.3 D, and in any
event including payment of the reimbursable costs pursuant to Section 11.3 B
unless previously paid by Licensee, and (iii) such other terms and conditions as
may be agreed by the Parties. Upon agreement by the Parties as to the foregoing
terms and conditions, the same shall be set forth in either a written amendment
to this Agreement or a separate written agreement between the Parties.

          D.    GeoTel shall perform the Software Development Services for any
Modifications during the Term based upon the rates set forth in Section C of
Exhibit C.

          E.    GeoTel agrees that it shall develop Programs with so-called 
"service bureau capabilities" (formerly referred to as "partitioning"), such
Programs hereinafter being referred to as the "Service Bureau Programs". GeoTel
acknowledges and agrees that it has determined that such Service Bureau Programs
are both technically feasible and consistent with the scope of GeoTel's core
business. GeoTel agrees that it shall develop the Service Bureau Programs
subject to the following:

                (i) GeoTel will commence developing the Service Bureau Programs
within sixty (60) days after the Effective Date and make such Service Bureau
Programs available for licensing by Licensee hereunder in their final generally
commercially available form by no later than sixteen (16) months from the
Effective Date;

                (ii) Licensee will participate in the development by GeoTel of
the Technical Specifications for the Service Bureau Programs but shall have no
liability for any costs, expenses


<PAGE>   31



or other moneys incurred by GeoTel in connection with that effort;

                (iii) Licensee will fund an acceleration of GeoTel's development
calendar to include completion of the Service Bureau Programs in the time frame
specified in Subitem (i) immediately above by placing an Order with GeoTel for
the amount of Two Hundred Fifty Thousand Dollars ($250,000) upon the completion
of the Technical Specifications for the Service Bureau Programs (the
"Acceleration Fee"), and except for payment of the Acceleration Fee by Licensee,
Licensee shall have no other obligation to fund any portion of the development
of the Service Bureau Programs by GeoTel;

                (iv) in consideration for payment of the Acceleration Fee, 
GeoTel will further grant Licensee credits in the amount of the Acceleration Fee
which Licensee shall be entitled to apply against fees for purchases of licenses
for the Service Bureau Programs hereunder, or, at Licensee's sole discretion,
instead as a credit against fees for purchases of any other Programs or Services
hereunder if: (x) the Service Bureau Programs are made available by GeoTel to
Licensee in final generally commercially available form at a list price per copy
that exceeds sixty percent (60%) of the then applicable Exhibit C list price
hereunder per copy of a dedicated call router Program as defined in Exhibit C,
Model Number 12002 or its functional equivalent; or (y) in Licensee's sole
judgment, the Service Bureau Programs do not meet the functional and performance
requirements of Licensee. Any fees for purchases by Licensee utilizing any
portion of the Acceleration Fee credit shall be considered as Eligible Purchases
hereunder and as such will be applied towards meeting the Purchase Commitment;
and

                (v) in the event that GeoTel does not make the Service Bureau
Programs conforming with the applicable Technical Specifications available in
final generally commercially available form for licensing by Licensee hereunder
by the date required pursuant to Subitem (i) immediately above, then the
Purchase Commitment shall from and after such due date be reduced by, and
Licensee shall be released from and have no further obligation or liability in
connection therewith, the amount of One Hundred Sixty Six Thousand Six Hundred
Sixty Six Dollars ($166,666) for every full calendar month after such due date
that the Service Bureau Programs are not made available for licensing by
Licensee in final generally commercially available form, provided that from and
after the date twenty four (24) calendar months from the Effective Date if such
failure to make the Service Bureau Programs so available continues, Licensee
shall further be entitled, at its option, in addition to the foregoing
continuing reduction in the Purchase Commitment, to obtain, and GeoTel shall be
obligated to provide, a prompt refund of the entire Acceleration Fee, provided,
further, however, that except to the extent of the remedies expressly provided
to Licensee pursuant to this Section 11.3 E(v) in the event of GeoTel's failure
to make the Service Bureau Programs so available by the date required pursuant
to Subitem (i) immediately above, such failure shall not otherwise be deemed a
material breach of this Agreement by GeoTel.

     11.4 ADDITIONAL SERVICES During the Term, Licensee may request, and GeoTel
may perform, services in connection with the Programs which GeoTel is not
otherwise required to perform under the terms of this Agreement (the "Additional
Services") and Licensee shall pay to GeoTel a mutually agreed upon fee based on
the fees set forth in Section C of Exhibit C, including

Designated Computers while in its possession or control during the performance
of any Services is and shall remain the property of Licensee, its bailor or its
designee, and GeoTel shall have no right, title or interest in or to such
Designated Computers other than the limited right of possession and use in order

hereunder. While in GeoTel's possession or control, GeoTel shall:

                (i) keep the Designated Computers in a secure environment, free

encumbrances;

                (ii) permit Licensee personnel or Licensee's designees

upon by Licensee and GeoTel. Licensee will take appropriate steps to assure that
the date for GeoTel installation will not be delayed due to non-availability of
such lines, circuits, local area or wide area network hardware or services.

     12.2 TELEPHONE ACCESS. Licensee shall provide at the installation site in
connection with Installation Services, at its expense, one telephone access line
for remote support and testing of the Programs and business use of GeoTel at the

13.  SOURCE CODE ESCROW

     13.1 ESCROW AGREEMENT Simultaneously with the execution of this Agreement,
the Parties shall execute an "Additional Party Agreement" in the form of
Appendix C to the Deposit Agreement that shall be effective as of the Effective
Date to secure Licensee's rights hereunder and which Licensee shall be entitled
to maintain in effect during the period specified in Section 13.6. GeoTel
expressly agrees that any and all breaches by, or liability of, Licensee under
or in connection with the Source Code Escrow Agreement and such Additional Party
Agreement shall be subject to the limitations of liability set forth in Section
10.1 ("Limitations") of this Agreement, and that any Source Code Materials or
other Source Code received by Licensee thereunder or hereunder shall be subject
to the provisions of Section 9.1 hereto. GeoTel agrees that at its sole expense
during the period specified in Section 13.6 it shall maintain the Deposit
Agreement in full force and effect with Data Securities International, Inc., or
should such Deposit Agreement with Data Securities International, Inc. terminate
or otherwise expire for any reason during such period, then GeoTel shall
immediately enter into a replacement escrow arrangement for the Source Code
Materials, as defined below, with a replacement independent escrow agent
mutually satisfactory to GeoTel and Licensee (Data Securities International,
Inc. or such replacement escrow agent, as applicable, hereinafter being referred
to as the "Escrow Agent") pursuant to a


<PAGE>   34



form of agreement either substantially similar in form to the Deposit Agreement
or as otherwise mutually agreed by the Parties and in any event in accordance
with the provisions of this Article 13 (the Deposit Agreement or such
replacement agreement, as applicable, hereinafter being referred to as the
"Source Code Escrow Agreement").

          A.    SOURCE CODE RELEASE. Release of the Source Code Materials to 
Licensee for a particular Program shall be on terms and conditions (including
notice, redeposit and other provisions) as set forth in the Source Code Escrow
Agreement, but in any event such release shall be granted if:

                (i) GeoTel becomes unable to support such Program by reason of 
insolvency, making an assignment for the benefit of creditors, having a receiver
appointed to manage its affairs, ceasing to do business or being adjudicated a
bankrupt under the laws of the United States; and

                (ii) Licensee's use of such Program is likely to be seriously 
impaired as a result.

          B     SOURCE CODE LICENSE. In the event that Licensee is furnished a
copy of any Source Code Materials, Licensee shall be authorized to use such
Source Code Materials only for the purpose of performing those support services
and Technical Support with respect to the affected Program that GeoTel was to
perform hereunder or as otherwise referred to in Section 13.6 at the time
Licensee is furnished such copy of the Source Code Materials. Any such Source
Code Materials shall be treated as proprietary and confidential material of
GeoTel under this Agreement and shall also be subject to all conditions and
restrictions set forth in Licensee's Additional Party Agreement under the Source
Code Escrow Agreement.

     13.2 SOURCE CODE MATERIALS; AUDIT The Source Code Materials required to be
deposited with the Escrow Agent as of the Effective Date pursuant to Section 9.2
A (x) shall be kept current so as to accurately reflect the Source Code for the
then Current Releases of the Programs either under license to Licensee or
otherwise available to Licensee pursuant to this Agreement from time to time and
promptly updated by GeoTel, but in any event no less frequently than following
each material upgrade, modification or enhancement thereto, including without
limitation any new Releases or Updates provided to Licensee hereunder, and the
same shall be part of the Source Code Materials. GeoTel shall designate a
mutually acceptable neutral third party who, at the expense and request of
Licensee made from time to time, shall audit the materials deposited with the
Escrow Agent under the Source Code Escrow Agreement for purposes of determining
whether GeoTel has fulfilled its deposit obligations. GeoTel will promptly
correct any deficiency disclosed by the audit.

     13.3 BANKRUPTCY, LIQUIDATION, ETC. The obligations of GeoTel under this
Article 13 shall extend to any trustee in bankruptcy, receiver, administrator or
liquidator appointed for


<PAGE>   35



GeoTel and GeoTel as debtor-in-possession ("Trustee"), as well as to any other
successor in interest to GeoTel. Without limiting the generality of the
foregoing, upon written request of Licensee, GeoTel shall not interfere with the
rights of Licensee as provided in this Agreement or the Source Code Escrow
Agreement to obtain the Source Code Materials from the Trustee, the escrowee or
any other person or entity having possession thereof, and shall, if requested
under the conditions specified in the Source Code Escrow Agreement for release
of the Source Code Materials, cause a copy of such Source Code Materials to be
made available to Licensee.

     13.4 DISPUTES REGARDING SOURCE CODE MATERIALS. Notwithstanding that GeoTel
has submitted the affidavit referred to in Section 4 of the Source Code Escrow
Agreement in response to Licensee's written notice to the Escrow Agent of the
occurrence of an Event of Release, as defined in said Section 4, or that a
dispute between GeoTel and Licensee pursuant to the Source Code Escrow
Agreement, including arising under Section 4, has been submitted to arbitration
pursuant to Section 5 of that agreement, the Parties agree that the Source Code
Materials shall nonetheless be released to Licensee by the Escrow Agent. If the
arbitrator(s) ultimately find that under the terms of this Agreement release of
the Source Code Materials to Licensee should not have occurred, Licensee shall
return the Source Code Materials to the Escrow Agent.

     13.5 FUTURE EVENTS. In the event that Licensee and GeoTel enter into a
separate agreement or an amendment to this Agreement providing for broader
distribution rights than set forth herein as of the Effective Date in which
Licensee becomes a reseller of GeoTel's Programs and Services, and/or services
based upon GeoTel's Programs and Services, directly or indirectly to the
end-user marketplace under Licensee's or third party private brand labels and is
marketing the Programs, Services and/or services as strategic Licensee products
and services, then GeoTel and Licensee will as a function of such separate
agreement or amendment to this Agreement negotiate in good faith the addition to
the then existing Source Code Escrow Agreement under this Agreement and any
escrow agreement under any such separate agreement a Source Code Materials
release trigger to address a failure of GeoTel to provide Technical Support.

     13.6 SURVIVAL. The obligations of GeoTel under this Article 13 shall
survive and remain in effect until the later to terminate or expire of (i) this
Agreement or (ii) any separate agreement or other arrangement between the
Parties with respect to Technical Support or other maintenance and support for
the Programs, including without limitation any such agreement or other
arrangement between the Parties pursuant to Section 11.1 A in effect after the
expiration or termination of this Agreement.

14.  GENERAL TERMS

the contrary, GeoTel and Licensee shall operate in the capacity of independent
contractors hereunder and nothing contained in this Agreement shall be deemed or
construed as creating a joint venture or partnership between GeoTel and
Licensee. Neither Party is by virtue of this Agreement authorized as an agent,
employee or legal representative of the other nor shall either Party have any
power or authority to bind or commit the other. Neither Party will represent to
any third


<PAGE>   36



parties that it has any right to enter into any binding obligation on the other
Party's behalf. Neither Party shall have power to control the activities and
operations of the other, it being intended that each Party is and at all times
will remain an independent contractor.

     14.2 SEVERABILITY. Wherever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under

invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity without invalidating the remainder of
such provision or the remaining provisions of this Agreement, and the prohibited
or invalid provision, to the extent of such prohibition or invalidity, shall be
replaced by a mutually acceptable provision which, being valid and enforceable,
comes closest to the intention of the Parties underlying the invalid or
unenforceable provision.

Agreement shall not constitute a waiver of any other or subsequent default or
breach.

State of New York, without reference to its choice of law provisions. This
Agreement will not be governed by the United Nations Convention for the

consent of the other Party, assign its rights and obligations hereunder, and at
such assigning Party's option, all of such Party's rights and obligations in
Program licenses then held by Licensee, to an Affiliate, or to a successor in
interest or to a purchaser of all or substantially all of the assets of that

further, however that where any such assignment without consent is made by
GeoTel pursuant to this clause to any of the entities or any Affiliates of such
entities as listed in Exhibit H ("Prohibited Entities for Assignment"), then as

have no further obligation or liability in connection with, and GeoTel shall be
deemed to have waived, the Purchase Commitment for the Contract Year in which
such assignment is effective as well as any Purchase Commitments for any
subsequent Contract Years, and Licensee and the assignee covered by Exhibit G as
to which GeoTel has made such assignment shall each further be entitled, at
their respective sole option, to terminate this Agreement by providing written

harmless against any expense, judgment or loss incurred in connection with any
action brought against GEOTEL based upon a claim that the manufacture or license
of any Program which is modified, altered or combined with any equipment or
software by OPTUS [or any of its Customers] and is not supplied by GEOTEL
hereunder constitutes an infringement because of such modification, alteration
or combination.

         16. TERM AND TERMINATION.
         -------------------------

                  (a) TERM. This Agreement shall remain in full force and effect
for an initial term ("Initial Term") commencing on the date hereof and extending

accordance with this Agreement. Notwithstanding the foregoing, OPTUS may provide
GEOTEL ninety (90) days notice any time after the first twenty four months of
this Agreement that it does not wish to continue this Agreement, in which case
this Agreement shall terminate at the end of that 90 day period, such
notification will not relieve or diminish in anyway OPTUS's obligations during
the initial term of this Agreement. This Agreement shall automatically renew for
consecutive one (1) year periods ("Extension Periods") based upon the terms and
conditions then contained in this Agreement, unless either Party provides
written notice to the other no later than ninety (90) days prior to the end of
the Initial Term or the then-current Extension Period of its intent to terminate
this Agreement in which event this Agreement shall terminate as of the end of
such Initial Term or Extension Period, as applicable. The Initial Term and any
Extension Periods may be collectively referred to in this Agreement as the Term.

                  (b) TERMINATION. This Agreement may also be terminated:

                           (i)   By GEOTEL, in the event that OPTUS fails to 
make royalty payments to GEOTEL when due under Section 11 hereof and fails to
remedy such breach within 60 days after written notice of such breach is
provided to OPTUS;

                           (ii)  By either party, if the other party breaches 
any of its obligations under this Agreement (other than OPTUS's obligation to
pay amounts due under this Agreement to GEOTEL) and fails to remedy such breach
within 60 days after written notice of such breach is provided to such other
party;

                           (iii) By either party, effective immediately and
without notice, if (A) a receiver, trustee, or liquidator of the other party is
appointed for any of the properties or assets of the other party; (B) either
party makes a general assignment for the benefit of its creditors; (C) either
party files a petition under the federal Bankruptcy Code or other federal or
state statue for the reorganization of the other party or any arrangement with
its creditors or readjustment of its debt, or its dissolution or liquidation, or
such a petition is flied against the other party and is not dismissed within 60
days thereafter; or (D) either party ceases doing business or commences
dissolution or liquidation proceedings.

         (c) EFFECT OF TERMINATION. Upon any termination of this Agreement, (i)
OPTUS shall immediately cease to grant OPTUS Sublicenses, (ii) all obligations
of either party incurred hereunder prior to such termination and all obligations
of either party set forth under Section 16 hereof shall survive the termination
of this Agreement and (iii) OPTUS shall return to GEOTEL (or at GEOTEL's option,
destroy and certify in writing to GEOTEL that it has destroyed) the original and
all copies of the Program and related documentation, including compilations,
translations, partial copies and modifications, if any.

         (d) SUPPORT SERVICES AFTER TERMINATION. Following expiration or
termination of this Agreement, OPTUS and GEOTEL will cooperate in the smooth
transition of the provision of the following to OPTUS Customers:, i)Warranty,
ii) Service and iii) Updates. GEOTEL may elect at it's sole discretion to: i)
continue to have OPTUS provide such services for a mutually agreed upon fee, ii)
appoint a new service provider in the Territory, iii) GEOTEL may provide such
services directly or iv) by any other means as GEOTEL may determine.

                                                                              10
<PAGE>   11


         17. RELATIONSHIP BETWEEN PARTIES. The relationship between GEOTEL and
OPTUS is that of independent contractors, and nothing in this Agreement shall be
construed to constitute one party as an employee, partner or agent of the other
party. Without limiting the foregoing, either party shall have any authority to
act for or to bind the other party in any way, to make representations or
warranties or to execute agreements on behalf of the other party or to represent
that the other party is in any way responsible for the acts or omissions of the
other party. Both parties shall indemnify and hold each other L harmless for any
liability or damage resulting from violation of this Section 17.

         18. EXPORT. OPTUS agrees that the Program products licensed hereunder
will not be exported directly or indirectly from the United States, separately
or as part of a system, without first obtaining a valid license from the United
States Government, as required, and otherwise in compliance with all United
States Government Export Regulations. OPTUS shall have sole responsibility for
obtaining all such licenses or other required permits at its sole cost and
expense. No failure to obtain any such license shall excuse any nonperformance
by OPTUS of its obligation pursuant to this Agreement. OPTUS's obligations under
this provision shall survive and continue after any termination of rights under
this Agreement.

         Specifically, not by way of limitation, as required by Part 179.4
(d)(2) of the Export Administration Regulations of the United States Department
of Commerce, OPTUS assures GEOTEL that, unless prior authorization is obtained
from the United States Office of Export Administration, OPTUS will not knowingly
export (or re-export) the Program products or the confidential and proprietary
information related thereto for any purpose, to any of the countries of Romania,
Poland, Albania, Bulgaria, Czechoslovakia, East Germany (Soviet Zone of Germany
and the Soviet sector of Berlin), Estonia, Hungary, Latvia, Lithuania, Outer
Mongolia, People's Republic of China ( excluding Republic of China), Taiwan
(Formosa), Union of Soviet Socialist Republics, North Korea, North Vietnam,
South Vietnam, Cambodia, Afghanistan, Cuba and Libya.

         19. TAXES. OPTUS shall pay all import duties, levies or imposts, and
all sales, use, value added, property, or other taxes of any nature, assessed
upon or with respect to any Programs, or other products or services ordered by
OPTUS from GEOTEL, which are imposed by any community of nations, nation, or
political subdivision thereof, but excluding United States taxes based on
GEOTEL's net income. If OPTUS is required by law to make any deduction or to
withhold from any sum payable to GEOTEL by OPTUS hereunder, then the sum payable
by OPTUS upon which the deduction or withholding is based shall be increased to
the extent necessary to ensure that, after all deduction and withholding, GEOTEL
receives and retains, free from liability for any deduction or withholding, a
net amount equal to the amount GEOTEL would have received and retained in the
absence of required deduction or withholding. In the event GEOTEL is required at
any time to pay any such tax, fee, duty or charge, OPTUS shall promptly
reimburse GEOTEL therefor. OPTUS shall obtain and provide to GEOTEL any
certificate of exemption or similar document required to exempt any transaction
under this Agreement from sales tax, use tax or other tax liability.

         20. FORCE MAJEURE. In the event that either party is prevented from
performing, or is unable to perform, any of its obligations under this Agreement
due to any act of God, fire, casualty, flood, war, strike, lock out, failure of
public utilities, injunction or any act, exercise, assertion or requirement of
governmental authority, epidemic, destruction of production facilities,
insurrection, inability to procure materials, labor, equipment, transportation
or energy sufficient to meet manufacturing needs, or any other cause beyond the
reasonable control of the party invoking this provision, and if such party shall
have used its best efforts to avoid such occurrence and minimize its duration
and shall have given prompt written notice to the other party, then the affected
party's performance shall be excused and the time for performance shall be
extended for the period of delay or inability to perform due to such occurrence.

         21. NOTICES. All notices or other communications given by either party
of the other under this Agreement shall be in writing and shall be personally
delivered or sent by registered or certified mail, return-receipt requested, to
the other party at its address set forth above or such other address as a party
may subsequently designate in writing. The date of personal delivery or the date
of mailing, as the case may be, shall be deemed to be the date on which such
notice is given.

                                                                              11
<PAGE>   12


         22. ENTIRE AGREEMENT. This Agreement and the Exhibits constitute the
entire agreement between GEOTEL and OPTUS with respect to the subject matter
hereof. No waiver, consent, modification, amendment or change of the terms of
this Agreement or of any Exhibit shall bind either party unless in writing and
signed by both parties.

         23. SEVERABLITY. In the event that any provision of this Agreement is
held by a court of competent jurisdiction to be unenforceable because it is
invalid or in conflict with any law of any relevant jurisdiction, the validity
of the remaining provisions shall not be affected, and the rights and
obligations of the parties shall be construed and enforced as if the Agreement
did not contain the particular provisions held to be unenforceable.

         24. ASSIGNMENTS PROHIBITED. Neither this Agreement nor any rights or
licenses granted hereunder may be assigned or delegated, by operation of law or
otherwise, without the written consent of the other party, which consent shall
not be unreasonably withheld; provided, however, that GEOTEL shall be entitled
to assign this Agreement to an entity which purchases substantially all of the
assets of GEOTEL or purchases a majority interest in the voting stock of GEOTEL
or otherwise assumes the business of GEOTEL.

         25. GOVERNING LAW. This Agreement shall be governed by and construed as
a sealed instrument in accordance with the laws of the Commonwealth of
Massachusetts.

         26. SURVIVAL OF PROVISIONS. Optus agrees that the provisions of
Sections 11, 12, 13, 14, 15, 16 (c), 16 (d), 18, 19, 21, 24, 25 and 26 shall
survive the expiration or earlier termination of this Agreement for any reason.

         IN WITNESS WHEREOF, the parties hereto executed this Agreement under
seal as of the day and year indicated above.

Notes:

 (1)  In accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 83, issuances of common
      stock, common stock equivalents and Series C Convertible Preferred Stock within one year prior of the initial 
      filing of the registration statement, at share prices below the assumed initial public offering price are
      considered to have been made in anticipation of the contemplated public offering for which this registration
      statement was prepared. Accordingly, these stock issuances are treated as if issued and outstanding,
      using the treasury stock method for options, since the inception of the Company.

 (2)  All shares of Convertible Preferred Stock are considered, on a pro forma basis, to be common
      stock and are included using the if-converted method on the dates of their original issuance.

 (3)  Fully diluted net income (loss) per share is not presented as it is the same as the amounts disclosed in
      historical net income (loss) per share for all periods presented.
