                               PROSPECTUS SUMMARY

     You should read the following summary together with the more detailed
information regarding Quintus and the common stock being sold in this offering
and the consolidated financial statements and related notes included in this
prospectus.

                              QUINTUS CORPORATION


     We provide a comprehensive e-Customer Relationship Management or eCRM
solution to manage customer interactions, such as customer orders, inquiries and
service requests, and deliver consistent customer service across multiple
communication channels, including the Internet, email and the telephone. Our
Quintus eContact software suite includes applications that address the needs of
customer service representatives and agents in sales and service, consumer
relations, technical support and human resources centers and a routing engine to
manage customer interactions. These applications and our routing engine can be
sold separately or in a group. eContact enables companies to handle high volumes
of customer interactions and leverage opportunities to sell additional products
and services to their customers.



     Customer service is increasingly critical to attracting and retaining
customers. Many companies are re-orienting their businesses to be more
responsive to customer needs and are focusing on customer satisfaction to
differentiate themselves from their competitors. In addition, the emergence of
the Internet as a medium for communication and commerce has increased
competition for customers and reduced the importance of traditional competitive
advantages such as price, location, availability and access. International Data
Corporation estimates that the number of customers buying goods and services
over the Internet worldwide will grow from approximately 30.8 million in 1998 to
182.6 million in 2003 and that the value of these purchases will increase from
$50.4 billion to $1.3 trillion over the same period.



     The Internet enables customers and companies to interact in more ways than
ever before. In addition to traditional, telephone-based communications,
customers and companies can now interact through email, Web chat and Web
self-service. The Gartner Group estimates that approximately 25% of all customer
interactions will take place over the Internet via email or Web communications
by 2001. As a result of the growing number of communication channels, companies
are struggling to handle the volume and variety of customer interactions.
Customers increasingly expect to be able to interact with companies through
whichever channel best suits their needs and are likely to use a combination of
communication channels. For example, a customer may request product literature
via email, review marketing materials or fill in an application on the Web, call
to receive more detailed information or assistance, send a signed form by fax,
and check the status of an order online. We believe a significant market
opportunity exists for integrated solutions that enable companies to manage
their customer relationships across a broad range of communication channels,
including the Internet, email and the telephone. This market is referred to as
the e-Customer Relationship Management or eCRM market.



     The Quintus eContact software suite allows companies to personalize, route
and manage customer interactions. Our eContact suite enables consistent customer
service through the use of common rules for prioritizing, handling and
responding to customer interactions, shared customer profile information,
uniform strategies for selling additional products and services to customers,
and consolidated management and reporting functions that allow companies to
capture and analyze customer information.

                                        3
<PAGE>   5

     The Quintus eContact suite includes:

     - the eContact engine, the foundation of our eContact suite, that routes,
       tracks and manages customer interactions, consolidates relevant customer
       information into a common data information source, and provides reporting
       capabilities that allow companies to analyze customer information;

     - channel applications that enable companies to manage customer
       interactions across multiple communication channels, including the
       Internet, email and the telephone; and


     - business applications that address the needs of customer service
       representatives and agents in sales and service, consumer relations,
       technical support and human resources centers and are integrated with our
       eContact engine.


     We only recently introduced and sold the email management and
Internet-based customer service components of our eContact suite. As a result no
customer has completed the implementation of these new components.

     In addition, we provide professional services, customer service management,
technical support and educational services to facilitate successful customer
implementations.

     Our objective is to be the leading provider of eCRM software solutions. Key
elements of our strategy include maintaining and extending our technology
leadership, broadening our direct and indirect distribution channels, targeting
Global 1000 and leading Internet-based companies, and developing and expanding
strategic relationships.

     We sell our products through a direct sales force in North America and
indirectly through resellers and distribution partners worldwide. We have over
250 customers across many industries including financial services,
telecommunications and consumer products. Our customers include Anheuser-Busch,
Citigroup, First Union Bank, Lucent Technologies, Procter & Gamble, Sun
Microsystems, Ticketmaster and United Airlines.

                             ACQUISITION OF ACUITY


     On September 10, 1999, we entered into an agreement to acquire Acuity
Corp., a provider of software products to manage Internet-based customer
interactions. We are currently integrating Acuity's WebCenter and WebACD
products into our Quintus eContact suite in order to provide a more
comprehensive eCRM solution. The acquisition is structured as a merger in which
Acuity will become our wholly-owned subsidiary and the stockholders of Acuity
will become our stockholders. The total number of our shares to be issued plus
the number of shares issuable upon exercise of options and warrants we will
assume in connection with the acquisition will equal 18% of our fully-diluted
capitalization immediately following the acquisition. The closing of the merger
is subject to the approval of Acuity's stockholders. Unless otherwise indicated,
all information in this prospectus assumes the closing of our acquisition of
Acuity prior to the effectiveness of this offering.

                                  RISK FACTORS

     An investment in our common stock involves a high degree of risk. You
should carefully consider the following risks and the other information in this
prospectus before investing in our common stock. Our business and results of
operations could be seriously harmed by any of the following risks. The trading
price of our common stock could decline due to any of these risks, and you may
lose all or part of your investment.

BECAUSE WE MAY NOT ACHIEVE PROFITABILITY, THE TRADING PRICE OF OUR COMMON STOCK
COULD DECLINE AND YOU COULD LOSE ALL OR PART OF YOUR INVESTMENT.

     We have not had a profitable quarter and we cannot assure you that we will
become profitable. We expect to increase our sales and marketing, research and
development, and other expenses as we attempt to grow our business. As a result,
we will need to generate significant revenues to become profitable, which we may
be unable to do. If we fail to become profitable, the trading price of our
common stock could decline significantly. We have funded our operations through
the sale of equity securities, borrowings and the sale of our products and
services. We incurred net losses from continuing operations of $3.5 million,
$10.1 million, $10.6 million and $1.7 million in fiscal 1997, 1998 and 1999 and
for the six months ended September 30, 1999. As of September 30, 1999 we had an
accumulated deficit of $36.3 million. In addition, in September 1999, we entered
into an agreement to acquire Acuity which had incurred net losses of $6.6
million, $7.7 million and $4.6 million in the years ended December 31, 1997 and
1998 and for the nine months ended September 30, 1999. Acuity had an accumulated
deficit of $25.3 million as of September 30, 1999. Upon the closing of the
acquisition of Acuity, we will record approximately $42.8 million of intangible
assets, which will be amortized on a quarterly basis over periods of four to
five years. In connection with the acquisition of Acuity, we expect to recognize
a charge for in-process technologies of approximately $3.0 million in the
quarter ending December 31, 1999.

BECAUSE WE RECENTLY EXPANDED THE SCOPE OF OUR PRODUCT OFFERING, IT MAY BE
DIFFICULT FOR YOU TO EVALUATE OUR BUSINESS PROSPECTS.

     In February 1999, we expanded the scope of our product offering with
components for managing email and Internet-based customer interactions and
introduced the Quintus eContact suite. As a result, while we sold many of the
components that are included in our eContact suite prior to 1999, we have only
recently sold the components for managing email and Internet-based customer
interactions. We sold our first email management and Internet-based customer
service components in the quarter ended September 30, 1999 and, as a result, no
customer has completed the implementation of these components. We cannot assure
you that our eContact suite will achieve market acceptance. In addition, we are
still integrating Acuity's WebCenter and WebACD products into our eContact
suite. We may encounter technical difficulties, delays and unforeseen expenses
as we continue our product integration and development efforts.

IF OUR INITIAL IMPLEMENTATIONS OF THE QUINTUS ECONTACT SUITE SUFFER PROBLEMS OR
DELAYS, OUR REPUTATION AND FUTURE OPERATING RESULTS MAY BE HARMED.

     We are just beginning to deploy our eContact suite. The initial
implementations of our eContact suite may encounter problems or delays. Although
we have successfully deployed some of the components of our eContact suite, we
have not deployed eContact with integrated computer telephony, email, Web chat
and Web self-service capabilities. To successfully implement our eContact suite,
we must complete the integration of its components and will likely have to
integrate eContact with a wide variety of complex systems currently used by our
customers. If these

                                        7
<PAGE>   9

implementations meet with significant technological obstacles, we may be forced
to spend additional resources, harming our operating results. If the ease and
speed of these implementations do not meet the expectations of our customers,
our reputation and ability to sell our eContact suite will be harmed.

BECAUSE OUR QUARTERLY REVENUES AND OPERATING RESULTS MAY FLUCTUATE
SIGNIFICANTLY, THE TRADING PRICE OF OUR COMMON STOCK IS LIKELY TO BE VOLATILE.

     It is likely that in some future quarter our revenues and operating results
will fall below the expectations of market analysts and investors. If this
happens, the trading price of our common stock may fall substantially. Our
revenues and operating results are likely to vary significantly from quarter to
quarter due to a variety of factors, including the risks we describe in this
section.

     Our ability to forecast revenues is limited. We derive substantially all of
our revenues from licenses of our software and related services. License
revenues in any quarter are substantially dependent on orders booked and shipped
in that quarter, and we cannot predict revenues for any future quarter with any
significant degree of certainty. In addition, we expect that sales derived
through indirect channels, which are more difficult to forecast, may increase as
a percentage of total revenues in the future. Our expenses are relatively fixed
and are based, in part, on our expectations of future revenues. Consequently, if
revenue levels do not meet our expectations, our operating results will suffer.

BECAUSE WE DEPEND UPON A LIMITED NUMBER OF LARGE SALES FOR A SUBSTANTIAL PORTION
OF OUR REVENUES, THE FAILURE TO OBTAIN LARGE PROSPECTIVE CUSTOMERS COULD CAUSE
OUR REVENUES TO FALL QUICKLY AND UNEXPECTEDLY.

     We depend upon a limited number of large sales for a substantial portion of
our revenues in each quarter. For example, in the six months ended September 30,
1999, our largest customer accounted for 12.6% of our total revenues. Our
failure to successfully close one or more large sales in any particular period
could cause our revenues to drop quickly and unexpectedly. We expect to continue
to be dependent upon a limited number of customers for a significant portion of
our revenues, and these customers are expected to vary from period-to-period.
The loss of prospective major customers could result in our failure to meet
quarterly revenue expectations, causing the trading price of our common stock to
fall.

WE RELY HEAVILY ON OUR INDIRECT DISTRIBUTION CHANNELS, PARTICULARLY OUR
DISTRIBUTION AGREEMENT WITH LUCENT TECHNOLOGIES.

     If Lucent Technologies were to cease reselling or fail to continue to
promote our products, our operating results would be harmed. Lucent Technologies
accounted for 9.3%, 21.7% and 28.3% of our total revenues in fiscal 1998 and
1999 and for the six months ending September 30, 1999. Our distribution
agreement with Lucent Technologies expires in May 2000 but can be terminated on
30 days' notice following a material breach of the agreement. Lucent
Technologies is not obligated to make any minimum purchases.

     In addition, the loss of a reseller, the failure of a reseller to sell our
products, or our failure to attract and retain qualified new resellers in the
future could also harm our business. Typically our resellers do not have minimum
purchase or resale obligations, can cease marketing our products at any time,
and may offer competing products. We intend to expand our indirect distribution
channels by establishing additional relationships with resellers and
distribution partners. Competition for these relationships is intense, and we
may be unable to establish relationships on favorable terms, if at all.

                                        8
<PAGE>   10

Even if we are successful in establishing these relationships, they may not
substantially increase our revenues.

BECAUSE A SUBSTANTIAL PORTION OF OUR REVENUES COMES FROM SALES OF OUR QUINTUS
CTI PRODUCT, OUR OPERATING RESULTS WILL SUFFER IF THESE SALES DO NOT CONTINUE.

     If sales of our Quintus CTI product do not meet our expectations, our
operating results will be harmed. Revenues from our Quintus CTI product were
38.4% and 32.1% in fiscal 1999 and for the six months ended September 30, 1999.
We expect that revenues from our Quintus CTI product will continue to account
for a substantial portion of our revenues in the future.

WE FACE A NUMBER OF RISKS RELATED TO OUR PENDING ACQUISITION OF ACUITY, AND WE
MAY FACE SIMILAR RISKS IN THE FUTURE IF WE ACQUIRE OTHER BUSINESSES OR
TECHNOLOGIES.

     In September 1999, we entered into an agreement to acquire Acuity and began
integrating its WebCenter and WebACD products into the Quintus eContact suite.
If we are unable to effectively integrate Acuity's products, personnel and
systems, our business and operating results are likely to suffer. This
integration will be made more difficult by Acuity's operations being located in
Austin, Texas, where we currently have no other operations. We have just begun
to integrate Acuity with our operations and we expect this integration to place
a significant burden on our management team.

     The acquisition of Acuity will be our third acquisition within the last
three years, and we may make more acquisitions in the future. If we are unable
to integrate effectively any newly acquired businesses, technologies or
products, our operating results could suffer. Integrating any newly acquired
businesses, technologies or products may be expensive and time-consuming. Future
acquisitions could also result in large and immediate write-offs for in-process
research and development, increased amortization charges or the incurrence of
debt and contingent liabilities. To finance acquisitions, we may need to raise
additional funds through public or private financings. Additional funds may not
be available on favorable terms, or at all, and, in the case of equity
financings, may result in dilution to our stockholders. Moreover, we may not be
able to operate any acquired businesses profitably or otherwise implement our
growth strategy successfully.

BECAUSE MANY OF OUR SALES PEOPLE ARE NEW HIRES AND HIRING ADDITIONAL SALES
PERSONNEL IS PARTICULARLY COMPETITIVE, WE MAY BE UNABLE TO EXPAND OUR BUSINESS.

     We have replaced a large number of our sales people during the last year.
As a result, the size of our sales force has not grown substantially, and many
of our sales personnel are new to us. We expect our new sales personnel will
require substantial training in our products and sales practices. New sales
personnel tend to be less productive than those with greater experience selling
our products. Moreover, we intend to hire additional direct sales force
personnel in the United States. Competition for qualified sales personnel is
particularly intense in the software industry. In the past, we have experienced
difficulty hiring employees with appropriate qualifications in the timeframe we
desired. Any delays or difficulties we encounter in these recruiting, training
or retention efforts could impair our ability to attract new customers and
enhance our relationships with existing customers.

BECAUSE THE ECRM MARKET IS HIGHLY COMPETITIVE, WE MAY NOT BE ABLE TO SUCCEED AND
YOU MAY LOSE PART OR ALL OF YOUR INVESTMENT.

     If we fail to compete successfully in the highly competitive and rapidly
changing eCRM market, we may not be able to succeed and you may lose part or all
of your investment. We face competition primarily from customer relationship
management software firms, emerging Internet customer

                                        9
<PAGE>   11

interaction software vendors and computer telephony software companies. We also
face competition from traditional call center technology providers, large
enterprise application software vendors, independent systems integrators,
consulting firms and in-house IT departments. Because barriers to entry into the
software market are relatively low, we expect to face additional competition in
the future.

     Many of our competitors can devote significantly more resources to the
development, promotion and sale of products than we can, and many of them can
respond to new technologies and changes in customer preferences more quickly
than we can. Further, other companies with resources greater than ours may
attempt to gain market share in the eCRM market by acquiring or forming
strategic alliances with our competitors. See "Business--Competition."

OUR ABILITY TO PROVIDE EMAIL MANAGEMENT FUNCTIONALITY WOULD BE HARMED IF WE
COULD NOT RESELL BRIGHTWARE'S EMAIL MANAGEMENT PRODUCT.

     We resell Brightware's software to provide the email management
functionality of the Quintus eContact suite. Our agreement with Brightware can
be cancelled without cause upon 60 days' notice. If Brightware were to cancel
our reseller agreement or be acquired by one of our competitors, or their email
management product were otherwise unavailable to us, we would likely incur
substantial delays and costs as we attempt to integrate alternative email
management functionality into our product suite. In particular, there may be few
alternative sources for Brightware's natural language text analysis and
automated email response functionality. In addition, if we were not able to
resell Brightware's product, companies requiring email management functionality
would have to purchase another product. As a result, the sales process with our
prospective customers would be complicated by the need to coordinate with a
third party.

OUR BUSINESS WILL SUFFER IF THE ECRM MARKET DOES NOT GROW.

     The eCRM market is new and may not grow. The use of email, Web chat and Web
self-service as channels for companies to interact with their customers is
recent and may not grow as expected. Our potential customers are just beginning
to look for solutions for managing customer interactions across multiple
communication channels, and concerns about the security, reliability and quality
of customer service delivery over the Internet may inhibit the growth of our
market. If eCRM software fails to achieve market acceptance, our business will
suffer and may not succeed.

BECAUSE WE DEPEND ON THIRD-PARTY SYSTEMS INTEGRATORS TO SELL OUR PRODUCTS, OUR
REVENUES WILL LIKELY SUFFER IF WE DO NOT DEVELOP AND MAINTAIN THESE
RELATIONSHIPS.

     We rely on systems integrators to promote, sell and implement our solution.
If we fail to maintain and develop relationships with systems integrators, our
revenues will likely suffer. We currently rely on systems integrators such as
AnswerThink Consulting Group, Cambridge Technology Partners and Technology
Solutions Company to recommend our products to their customers and to install
our products. If we are unable to rely on systems integrators to implement our
products, we will likely have to provide these services ourselves, resulting in
increased costs. As a result, our ability to grow may be harmed. In addition,
systems integrators may develop, market or recommend products that compete with
our products. For this reason, we must cultivate our relationships with these
firms, and our failure to do so could result in reduced sales revenues. Further,
if these systems integrators fail to implement our products successfully, our
reputation may be harmed.

                                       10
<PAGE>   12

BECAUSE THE SALES CYCLE FOR OUR PRODUCTS CAN BE QUITE LENGTHY, IT IS DIFFICULT
FOR US TO PREDICT WHEN OR WHETHER A SALE WILL BE MADE.

     The timing of our revenues is difficult to predict in large part due to the
length and variability of the sales cycle for our products. Companies often view
the purchase of our products as a significant and strategic decision. As a
result, companies tend to take significant time and effort evaluating our
products. The amount of time and effort depends in part on the size and the
complexity of the deployment. This evaluation process frequently results in a
lengthy sales cycle, typically ranging from three to nine months. During this
time we may incur substantial sales and marketing expenses and expend
significant management efforts. We do not recoup these investments if the
prospective customer does not ultimately license our product.

IF WE ARE UNABLE TO INTRODUCE NEW ECRM PRODUCTS OR PRODUCT ENHANCEMENTS ON A
TIMELY BASIS, OR IF THE MARKET DOES NOT ACCEPT THESE PRODUCTS OR PRODUCT
ENHANCEMENTS, OUR BUSINESS WILL SUFFER.

     The eCRM market is new and is likely to change rapidly. Our future success
will depend on our ability to effectively and timely anticipate changing
customer requirements and offer products and services that meet these demands.
Potential customers may seek features that our products do not have. As a
result, we may need to develop these features, and this may result in a longer
sales cycle, increased research and development expenses and reduced profit
margins. In addition, the development of new or enhanced eCRM products is a
complex and uncertain process. We may experience design, development, marketing
and other difficulties that could delay or prevent the introduction of new
products and enhancements. For example, our ability to introduce new products
would be impaired if we cannot continue to attract, hire, train and retain
highly skilled personnel.

OUR FAILURE TO MANAGE OUR RAPID GROWTH COULD INCREASE OUR COSTS AND HARM OUR
BUSINESS.

     We have experienced rapid growth and plan to continue to significantly
expand our operations. We may not be able to manage this growth effectively,
which would impair our ability to attract and service customers and cause us to
incur higher operating costs. Expanding our operations has placed a significant
strain on our personnel and other resources. Our revenues have grown from $13.6
million in fiscal 1997 to $30.3 million in fiscal 1999. Our headcount increased
from 113 at the end of fiscal 1997 to 158 at the end of fiscal 1999. For the six
months ended September 30, 1999, our revenues were $22.1 million and our
headcount was 208 at the end of that period. Our planned acquisition of Acuity
will bring additional employees and operations to manage. As of September 30,
1999, Acuity had 81 employees. To manage our growth effectively, we may need to
further improve our operational, financial and management systems. We cannot
assure you that we will improve these systems adequately.

IF WE DO NOT SUCCESSFULLY ADDRESS THE RISKS INHERENT IN THE EXPANSION OF OUR
INTERNATIONAL OPERATIONS, OUR OPERATING RESULTS MAY SUFFER.

     We have limited experience in international operations and may not be able
to compete effectively in international markets. We currently intend to expend
significant financial and management resources to expand our international
operations. We believe that the future expansion of our international operations
is important to the growth of our business. Most of our international sales are
generated through resellers and distributors, and we expect substantial costs
and resources will be required to continue to train and support these resellers.

                                       11
<PAGE>   13

     Among the various risks we face in conducting business internationally are:

     - difficulties and costs of staffing and managing foreign operations;

     - longer accounts receivable payment cycles and possible difficulties in
       collecting accounts receivable, which may increase our operating costs
       and hurt our financial performance;

     - technology standards that are different from those on which our products
       are designed, which could require expensive redesigns of our products;

     - political and economic instability;

     - unexpected changes in regulatory requirements that could make our
       products and services more expensive and therefore less attractive to
       potential customers; and

     - fluctuations in currency exchange rates and the imposition of currency
       exchange controls.

BECAUSE WE DEPEND ON LICENSED THIRD-PARTY TECHNOLOGIES, WE WILL FACE ADDITIONAL
COSTS IF WE HAVE TO REPLACE THESE TECHNOLOGIES.

     Our products incorporate technologies that we license from third parties.
Although we believe we could obtain similar technologies from alternative
sources, substituting and integrating replacement technologies could require us
to divert significant resources. These efforts, if required, could delay the
shipment of existing products and could delay the introduction of new products
or enhancements as a result of the diversion of development resources. In
addition, we may be required to license replacement technologies on terms less
favorable than our current terms, which would increase our expenses. If we are
unable to obtain the third-party technologies necessary for the successful
operation of our products, our business would be harmed.

UNKNOWN SOFTWARE DEFECTS COULD HARM OUR BUSINESS AND REPUTATION.

     Our software interacts with other complex systems and software. Our
software products may contain defects, particularly when first introduced.
Despite our software testing procedures, we may not discover software defects
that affect our products until after they are deployed. These defects could
result in:

     - damage to our reputation;

     - product returns or lost sales;

     - product liability claims against us;

     - delays in or loss of market acceptance of our products; and

     - unexpected expenses and diversion of resources to remedy errors.

The occurrence of any of these events would hurt our operating results. In
addition, our customers generally use our products together with products from
other vendors. As a result, when problems occur, it may be difficult to identify
the source of the problem. Therefore, even if these problems are not caused by
our products, they may cause us to incur significant warranty and repair costs,
divert the attention of our engineering personnel and cause significant customer
relations problems.

                                       12
<PAGE>   14

ALTHOUGH WE HAVE TAKEN MEASURES TO PROTECT OUR INTELLECTUAL PROPERTY, OUR
COMPETITIVE POSITION MAY SUFFER IF THESE MEASURES PROVE TO BE INADEQUATE.

     Third parties may infringe or misappropriate our copyrights, trademarks and
similar proprietary rights. We cannot be certain that the steps we have taken to
prevent the misappropriation of our intellectual property are adequate,
particularly in foreign countries where the laws may not protect our proprietary
rights as fully as in the United States. We rely on a combination of patent,
copyright, trademark and trade secret laws and restrictions on disclosure to
protect our intellectual property rights. In addition, we enter into
confidentiality agreements with our employees and certain customers, vendors and
strategic partners. Quintus has one issued U.S. patent and one filed U.S. patent
application. Through our acquisition of Acuity, we will acquire one additional
issued U.S. patent as well as nine additional filed U.S. patent applications. We
cannot assure you that any patents will be issued from these applications or
that any issued patent will protect our intellectual property. Furthermore,
other parties may independently develop similar or competing technology or
design around any patents that may be issued to us.

WE MAY FACE COSTLY INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS.

     Companies have in the past alleged that our products infringe their
patents, and others may make similar allegations in the future. Such claims or
other claims that our products infringe other intellectual property rights, may
force us to seek expensive licenses, re-engineer our products, engage in
expensive and time-consuming litigation or stop marketing the challenged
product. Further, by contract we typically indemnify our customers against
infringement claims related to our products. Intellectual property litigation is
expensive and time-consuming and could divert management's attention away from
running our business. This litigation could also require us to develop non-
infringing technology or enter into royalty or license agreements. These royalty
or license agreements, if required, may not be available on acceptable terms, if
at all. Our failure or inability to develop non-infringing technology or license
the proprietary rights on a timely basis in a cost-effective manner would harm
our business.

WE COULD LOSE REVENUES AND INCUR SIGNIFICANT COSTS IF OUR SYSTEMS OR THE SYSTEMS
OF OUR CUSTOMERS OR SIGNIFICANT THIRD PARTIES ARE NOT YEAR 2000 COMPLIANT.

     We may experience material problems and costs associated with the Year 2000
and our Year 2000 compliance efforts. If our eContact suite of products,
including those software components that we license from others, do not
correctly recognize date information when the calendar year changes to 2000, we
could experience warranty or other claims by our customers. These claims could
be costly to defend and could result in judgments against us.

     If our internal systems, such as engineering and finance applications, are
not Year 2000 compliant, we could experience problems running our day-to-day
business. In such a case, product development efforts could be delayed, and we
may be unable to adequately respond to the needs and concerns of our customers.
Further, if systems generally are not Year 2000 compliant, we may not be able to
obtain adequate supplies if our suppliers experience Year 2000 problems, and
companies could reduce their spending on eCRM products if they redirect
resources toward Year 2000 remediation programs. See "Business -- Year 2000
Compliance."

     We have made significant efforts to ensure that our proprietary software,
the software we license from others and our internal systems are Year 2000
compliant. We believe that no serious problems will arise that will result in
significant costs. However, a reasonable "worst case" scenario might include:

                                       13
<PAGE>   15


     - Cash expenditures and lost person-hours. If certain functions of our
       eContact suite fail, our customers may be unable to manage the operations
       of their customer service centers and we may be forced to spend time and
       money to correct these deficiencies.


     - Alternative use problems. We have certified the eContact software
       components, whether internally developed or licensed from others, as Year
       2000 compliant in the eCRM field of use. If any of our customers have
       adopted and are using eContact for alternative uses, they may face
       problems that we are not aware of.

     - Failure of engineering applications. While we have certified as Year 2000
       compliant our material internal systems, it is possible that some of our
       non-critical, narrow use engineering applications will experience
       difficulties. Although we have no reason to believe that these
       applications will fail, some areas of our engineering efforts could be
       hindered if problems arise.


WE MAY FACE YEAR 2000-RELATED CLAIMS IN CONNECTION WITH PRIOR VERSIONS OF
ACUITY'S PRODUCTS.



     Acuity has determined that certain older versions of its WebCenter software
product are not Year 2000 compliant. Acuity has attempted to contact all
customers with noncompliant products to notify them of this lack of compliance
and to offer them the opportunity to purchase a product upgrade that is Year
2000 compliant. We cannot assure you that customers of Acuity who experience
Year 2000 failures will not seek damages from Acuity or Quintus. In addition,
Acuity previously sold an iChat product that was not Year 2000 compliant. Acuity
sold its iChat product line prior to entering an agreement to be acquired by us.
We believe that any liabilities that result from the iChat product's failure to
be Year 2000 compliant will be the responsibility of the purchaser of the iChat
product line; however, third parties might still seek to assert liability
against us following our acquisition of Acuity.


SALES OF OUR COMMON STOCK INTO THE PUBLIC MARKET FOLLOWING THIS OFFERING COULD
HARM THE MARKET PRICE OF OUR COMMON STOCK AND OUR ABILITY TO RAISE MONEY THROUGH
SALES OF EQUITY SECURITIES.


     The value of your investment in our common stock and our ability to raise
money through the sale of additional equity securities could be adversely
affected if our existing stockholders sell large amounts of their Quintus common
stock into the public market. If significant volumes of our common stock are
sold into the public market, the market price of our common stock and therefore
the value of your investment could fall. This could impair our ability to raise
capital through the sale of additional equity securities. Based on shares
outstanding as of September 30, 1999, upon completion of this offering, we will
have 31,124,685 shares of common stock outstanding. The holders of substantially
all of our currently outstanding stock are subject to lock-up agreements or
bylaw restrictions providing that, with certain limited exceptions, the holders
will not sell or otherwise dispose of any shares of our common stock for a
period of 180 days after the date of this prospectus without the prior written
approval of Donaldson, Lufkin & Jenrette Securities Corporation. When these
lock-up agreements and bylaw restrictions expire, many of these shares and the
shares of common stock underlying any options held by these individuals will
become eligible for sale. See "Shares Eligible for Future Sale."


THERE MAY BE NO ACTIVE TRADING MARKET IN OUR COMMON SHARES AFTER THIS OFFERING,
WHICH MAY MAKE IT DIFFICULT FOR YOU TO RESELL YOUR SHARES.

     There has been no public trading market for our common shares prior to this
offering, and we cannot be sure that an active trading market will develop upon
completion of this offering or, if one does develop, that it will be sustained.
If no public trading market for our common shares develops,

                                       14
<PAGE>   16

or if this market is not active or sustained, it may be difficult for you to
resell your shares at a price at or above the initial public offering price.

CONTROL BY EXISTING STOCKHOLDERS MAY LIMIT YOUR ABILITY TO INFLUENCE THE OUTCOME
OF DIRECTOR ELECTIONS AND THE APPROVAL OF MERGERS OR OTHER BUSINESS
COMBINATIONS.


     Upon completion of this offering, our executive officers, directors and
principal stockholders and their affiliates will beneficially own 18,288,434
shares, or approximately 56.4%, of the outstanding shares of common stock. If
they were to act in concert, these stockholders would be able to significantly
influence all matters requiring approval by our stockholders, including the
election of directors and the approval of mergers or other business combination
transactions.


ANTI-TAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS, AS WELL AS PROVISIONS OF
EMPLOYMENT AGREEMENTS OF SOME OF OUR KEY EXECUTIVE OFFICERS, COULD PREVENT OR
DELAY A CHANGE IN CONTROL OF QUINTUS.

     Provisions in our bylaws and in our certificate of incorporation may have
the effect of delaying or preventing a change of control or changes in
management of Quintus. These provisions include:

     - the requirement that a special meeting of stockholders may only be called
       by stockholders owning at least a majority of our outstanding shares;

     - the ability of our board of directors to issue preferred stock without
       stockholder approval; and

     - the right of our board of directors to elect a director to fill a vacancy
       created by the expansion of the board of directors.

     In addition, some of our officers have agreements with us that provide for
acceleration of vesting following certain sales or mergers of Quintus. These
provisions could make our acquisition by a third party more costly and could
delay or prevent a change of control or changes in our management.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements. These statements
relate to future events or our future financial performance. In some cases, you
can identify forward-looking statements by terminology such as "may," "will,"
"should," "expect," "plan," "anticipate," "believe," "estimate," "predict,"
"potential" or "continue," the negative of such terms or other comparable
terminology. These statements are only predictions. Actual events or results may
differ materially. In evaluating these statements you should specifically
consider various factors, including the risks outlined under "Risk Factors."
These factors may cause our actual results to differ materially from any
forward-looking statement. Although we believe that the expectations reflected
in the forward-looking statements are reasonable, we cannot guarantee future
results, levels of activity, performance or achievements.

                                USE OF PROCEEDS

     We estimate that the net proceeds from the sale of 4,000,000 shares of
common stock we are offering will be approximately $47.2 million at an assumed
initial public offering price of $13.00 and after deducting estimated offering
expenses of approximately $1.2 million and underwriting discounts and
commissions payable by Quintus. If the underwriters exercise their
over-allotment option in full, then the net proceeds will be approximately $54.4
million.


     Under the terms of our certificate of incorporation in effect prior to this
offering, we are required to make a payment of approximately $18.2 million upon
the closing of this offering to the current holders of our Series A, Series B,
Series C and Series D preferred stock as a result of the conversion of this
preferred stock into common stock. We expect to use the remaining net proceeds
for working capital and other general corporate purposes. Some of the net
proceeds will be used to fund the expansion of our sales force and our
international operations. We currently estimate that during the next 12 months
we will incur at least $25 million to fund sales and marketing expenses, of
which at least $5 million will fund international operations. A portion of the
net proceeds may also be used to acquire or invest in complementary businesses,
technologies, product lines or products. We have no current plans, agreements or
commitments with respect to any such acquisitions or investments other than the
pending closing of our acquisition of Acuity. We will use shares of our capital
stock to complete this acquisition. Our management will have broad discretion
concerning the use of the net proceeds of this offering. We intend to invest
these proceeds in investment grade, interest-bearing securities pending their
use.


                                DIVIDEND POLICY

     We have never declared or paid any dividends on our common stock or other
securities. We currently expect to retain future earnings, if any, for use in
the operation and expansion of our business and do not anticipate paying cash
dividends in the future. Our existing bank line of credit prohibits the payment
of cash dividends.

     The following table sets forth our cash position, current portion of
long-term obligations and total capitalization as of September 30, 1999. The pro
forma column of the table gives effect to the issuance of an estimated 4,551,441
shares and the assumption of approximately $1.8 million in debt in connection
with our acquisition of Acuity.

     The pro forma as adjusted column of the table gives effect to the:

       warrants that otherwise terminate upon the closing of this offering;

     - conversion of all outstanding shares of our preferred stock into shares
       of our common stock upon the closing of this offering;

     - required payment of approximately $18.2 million to holders of some series
       of our preferred stock upon conversion of our preferred stock into our
       common stock; and

     - sale in this offering of 4,000,000 shares of common stock at an assumed
       initial public offering price of $13.00 per share, less underwriting
       discounts and commissions and estimated offering expenses payable by
       Quintus.

                                    DILUTION


     Our pro forma net tangible book value as of September 30, 1999, was $(13.0)
million, or approximately $(0.48) per share. Pro forma net tangible book value
per share represents the pro forma stockholders' equity less pro forma
intangible assets divided by the pro forma number of shares of common stock
outstanding, giving effect to the conversion of all outstanding shares of
preferred stock, the estimated 4,551,441 shares to be issued in connection with
the closing of the acquisition of Acuity and the issuance of 328,649 shares upon
the assumed exercise of outstanding warrants that otherwise terminate upon the
closing of this offering. After giving effect to the sale of the 4,000,000
shares of common stock being offered at an assumed initial public offering price
of $13.00 per share and after deducting the estimated underwriting discounts and
commissions and estimated offering expenses payable by us, our pro forma net
tangible book value at September 30, 1999, would have been $34.2 million, or
approximately $1.10 per share. This represents an immediate increase in pro
forma net tangible book value of $1.58 per share to existing stockholders and an
immediate dilution in net tangible book value of $11.90 per share to new
investors of common stock in this offering. The following table illustrates this
dilution on a per share basis:

     The following table sets forth, on a pro forma basis as of September 30,
1999, the differences between the number of shares of common stock purchased,
the total consideration paid and the average price per share paid by existing

offering, before deducting underwriting discounts and commissions and estimated
offering expenses payable by us, at the assumed public offering price of $13.00

     To the extent that any shares are issued upon exercise of options or
warrants that were outstanding at September 30, 1999 or granted after that date,
or reserved for future issuance under our stock plans, there will be further
dilution to new investors.

                      SELECTED CONSOLIDATED FINANCIAL DATA

     The following selected consolidated financial data should be read in
conjunction with our consolidated financial statements and the related notes and
with "Management's Discussion and Analysis of Financial Condition and Results of
Operations" included elsewhere in this prospectus.

     The consolidated statements of operations data for the years ended March
31, 1997 and 1998 and consolidated balance sheet data as of March 31, 1998 are
derived from our consolidated financial statements included elsewhere in this
prospectus, which have been audited by Ernst & Young LLP. The consolidated
statements of operations data for the year ended March 31, 1999 and consolidated
balance sheet data as of March 31, 1999 are derived from our consolidated
financial statements included elsewhere in this prospectus, which have been
audited by Deloitte & Touche LLP. The consolidated statements of operations data
for the period from May 25, 1995, the date of the acquisition of Quintus from
Intergraph Corporation in a management-led buyout with the financial backing of
new investors, to March 31, 1996 and balance sheet data as of March 31, 1996 and
1997 are derived from financial statements audited by Ernst & Young LLP, which
are not included in this prospectus. Prior to May 25, 1995, we were a
wholly-owned subsidiary of Intergraph Corporation. The financial data for the
year ended and as of March 31, 1995 is derived from Company's predecessor entity
financial records. In connection with the acquisition of Quintus from
Intergraph, in-process technology of $6.1 million and purchased software of
$398,000 was recorded. These amounts were charged to the Company's operations
during the year ended March 31, 1996.


     During July 1997 and November 1997, we acquired Call Center Enterprises,
Inc. and Nabnasset Corporation, respectively. In connection with these
acquisitions, we acquired intangible assets of approximately $10.8 million,
which are being amortized over a three year period, and we recorded a charge for
approximately $2.2 million for in-process research and development costs during
the year ended March 31, 1998. These transactions are described in detail at
Note 2 of our notes to our Consolidated Financial Statements included elsewhere
in this prospectus.


     The consolidated statements of operations data for the six months ended
September 30, 1998 and 1999 and the consolidated balance sheet data as of
September 30, 1999 are derived from our unaudited consolidated financial
statements which, in the opinion of management, have been prepared on the same
basis as the audited consolidated financial statements and reflect all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of our results of operations and financial position. The
historical results presented below are not necessarily indicative of the results
to be expected for any future period.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     You should read the following discussion and analysis of our financial
condition and results of operations in conjunction with our consolidated
financial statements and related notes included elsewhere in this prospectus.
This discussion and analysis contains forward-looking statements that involve
risks, uncertainties and assumptions. Our actual results may differ materially
from those anticipated in these forward-looking statements as a result of
certain factors, including, but not limited to, those set forth under "Risk
Factors" and elsewhere in this prospectus.

OVERVIEW


     Quintus was incorporated in 1984 to develop artificial intelligence
software and was acquired in 1989 by Intergraph Corporation, a provider of
interactive computer graphics systems. Quintus was purchased from Intergraph in
May 1995 in a management-led buyout with the financial backing of new investors.
At the time of the buyout we primarily provided application software and
consulting services to the help desk market. Since then we have introduced
several customer relationship management applications for call centers. In
November 1997, we acquired Nabnasset Corporation, a provider of computer
telephony integration software. Following the acquisition we introduced our
Quintus CTI product and began integrating it with our customer relationship
management applications. As new communication channels have emerged, we have
introduced new products and added functionality to our existing products. In
February 1999, we introduced our Quintus eContact suite as a platform for
integrating our existing products with new channel applications. As part of our
eContact suite, we also resell an email management product from Brightware. In
September 1999, we entered into an agreement to acquire Acuity, a provider of
software products to manage Internet-based customer interactions. The
acquisition is expected to close prior to the effectiveness of this offering.


     Our revenues were $13.6 million, $21.9 million, $30.3 million and $22.1
million in fiscal 1997, 1998 and 1999 and for the six months ended September 30,
1999. We derive substantially all of our revenues from licenses and services
associated with our products. License revenues are derived from product sales to
customers and through resellers and distributors. Service revenues are
attributable to the installation, consulting, maintenance and other support
services related to the sale of our products.

     License revenues from sales to end users are recognized upon shipment of
the product, if a signed contract exists, the fee is fixed and determinable,
collection is deemed probable and vendor-specific objective evidence exists to
allocate the total fee to elements of the arrangement. License revenues for
contracts requiring us to provide significant customization services are
recognized using percentage of completion accounting using labor days as the
basis for determining the percentage complete. License revenues from sales to
resellers and distributors are generally recognized at the time a reseller or
distributor reports to us that they have sold our software and all revenue
recognition criteria have been met.

     Service revenues include maintenance revenues which are deferred and
recognized ratably over the maintenance period, which in most cases is one year,
and revenues from training and consulting services, which are recognized as
services are performed.

     We sell our products to customers in North and South America, Europe, South
Africa and Japan. Sales to customers outside of the United States represented
15.3%, 14.0%, 18.3% and 13.8% of total revenues in fiscal 1997, 1998 and 1999
and for the six months ended September 30, 1999. All of our sales are
denominated in U.S. dollars. We intend to establish additional distribution
relationships

                                       22
<PAGE>   24

with partners outside of the United States and expect international revenues to
continue to increase as a percent of our total revenues in the future.

     We sell our products through a direct sales force and indirectly through
resellers and distribution partners. Lucent Technologies, which began reselling
our products in November 1997, accounted for 9.3%, 21.7% and 28.3% of total
revenues in fiscal 1998 and 1999 and for the six months ended September 30,
1999. In fiscal 1997, one customer, State Farm Insurance, accounted for 23.8% of
total revenues. In fiscal 1998 and 1999, no customer accounted for more than 10%
of total revenues. For the six months ended September 30, 1999, one customer,
Procter & Gamble, accounted for 12.6% of total revenues. We expect that sales of
our products to a limited number of parties will continue to account for a large
percentage of total revenues for the foreseeable future.

     In July 1997, we acquired Call Center Enterprises, a provider of strategic
call center consulting services, for $965,000 in cash. The acquisition was
accounted for as a purchase. In February 1999, we sold this business to
AnswerThink Consulting Group for $2.1 million in cash. The results of operations
for Call Center Enterprises are presented as discontinued operations in our
consolidated financial statements.

     In November 1997, we acquired Nabnasset for $3.5 million in cash, stock and
options to purchase our common stock. The transaction was accounted for as a
purchase. In this acquisition, acquired technology included both existing
technology and in-process research and development. The valuation of acquired
technology was made by applying the income forecast method, which considers the
present value of cash flows by product lines. Acquired in-process technologies
were charged to operations, as the technologies did not have alternative future
uses as of the date of the acquisition.

     As of September 30, 1999 we had an accumulated deficit of approximately
$36.3 million. Our net loss from continuing operations was $3.5 million, $10.1
million, $10.6 million and $1.7 million in fiscal 1997, 1998 and 1999 and for
the six months ended September 30, 1999. These losses resulted from costs
incurred in the development and sale of our products and services. We expect to
continue to experience significant growth in our operating expenses,
particularly in the areas of sales and marketing. As a result, we expect to
incur additional losses and cannot assure you that we will achieve or sustain
profitability in the future.

</TABLE>

SIX MONTHS ENDED SEPTEMBER 30, 1998 AND 1999

     REVENUES

     Total Revenues. Total revenues increased 39.3% from $15.9 million to $22.1
million for the six months ended September 30, 1998 and 1999.

     License. License revenues increased 34.7% from $9.9 million to $13.3
million for the six months ended September 30, 1998 and 1999. The increase in
license revenues was primarily due to an increase in products sold through
Lucent Technologies from $3.1 million to $5.3 million for the six months ended
September 30, 1998 and 1999, and a large direct sale of $2.1 million to Procter
& Gamble.

     Service. Service revenues increased 47.0% from $5.9 million to $8.7 million
for the six months ended September 30, 1998 and 1999. The growth in service
revenues was due primarily to an increase in maintenance revenues from $3.2
million to $4.6 million for the six months ended September 30,

                                       24
<PAGE>   26

1998 and 1999 as a result of our increased installed base. The growth in service
revenues was also due to an increase in consulting service revenues from new and
existing customers from $2.7 million to $4.2 million for the six months ended
September 30, 1998 and 1999. In future periods, we expect service revenues to
decrease as a percentage of total revenues as we seek to have third-party system
integrators undertake a greater percentage of our product implementation.

     COST OF REVENUES

     License. Cost of licenses consists primarily of royalties, product
packaging, documentation and production. Cost of licenses was $268,000 and
$671,000 for the six months ended September 30, 1998 and 1999, representing 2.7%
and 5.0% of license revenues in the respective periods. The increase was
primarily due to an increase in license revenues and the resulting increase in
third-party royalty payments and to a lesser extent increases in material costs
and other related expenses. Recently, we have entered into a reseller agreement
with Brightware which requires significantly higher royalty rates. Although the
sale of products under this agreement have been minimal to date, the cost of
licenses may vary significantly in the future, depending on the mix of
internally developed and third-party products.

     Service. Cost of services consists primarily of personnel costs and
third-party consulting fees associated with implementation, customization,
maintenance and other support services. Cost of services was $4.2 million and
$5.1 million for the six months ended September 30, 1998 and 1999, representing
70.2% and 58.0% of service revenues in the respective periods. The dollar
increase was primarily due to an increase in the number of third-party
consultants we engaged. Cost of services as a percentage of service revenues
declined primarily due to the higher margins for maintenance revenues. The cost
of services as a percentage of service revenues may vary between periods due to
the mix of services provided and the resources used to provide these services.

     OPERATING EXPENSES


     Sales and Marketing. Sales and marketing expenses consist primarily of
salaries, commissions, bonuses, travel, public relations, marketing materials
and trade shows. Sales and marketing expenses increased 9.5% from $8.6 million
to $9.4 million for the six months ended September 30, 1998 and 1999,
representing 54.3% and 42.7% of total revenues in the respective periods. The
increase in sales and marketing expenses was primarily due to higher
international operating expenses, which increased from $400,000 to $1.7 million
for the six months ended September 30, 1998 and 1999, offset by lower spending
on marketing programs. We formed our first foreign subsidiary in July of 1998.
We intend to invest substantial resources to expand our direct sales force and
other distribution channels, and to conduct marketing programs to support our
existing and new product offerings. As a result, sales and marketing expenses
are expected to increase in future periods.


     Research and Development. Research and development expenses consist
primarily of personnel and related expenses associated with the development of
new products, the enhancement and localization of existing products, and quality
assurance and testing costs incurred prior to commercial production. Research
and development expenses increased 18.5% from $3.4 million to $4.0 million for
the six months ended September 30, 1998 and 1999, representing 21.1% and 18.0%
of total revenues in the respective periods. The decline in research and
development expenses as a percentage of total revenues was primarily due to the
growth in total revenues. We anticipate that research and development expenses
will increase in future periods. To date, all research and development costs
have been expensed as incurred.

     General and Administrative. General and administrative expenses consist
primarily of salaries and other related costs for finance and human resource
employees, as well as accounting, legal, other

                                       25
<PAGE>   27


professional fees and allowance for doubtful accounts. General and
administrative expenses increased 22.1% from $1.6 million to $2.0 million for
the six months ended September 30, 1998 and 1999, representing 10.3% and 9.0% of
total revenues in the respective periods. The dollar increase was primarily due
to increased staffing costs of $318,000 and associated expenses necessary to
manage and support our increased scale of operations. We anticipate that our
general and administrative expenses will continue to increase as a result of the
continued expansion of our administrative staff and facilities to support
growing operations.


     Amortization of Intangibles. Amortization of intangibles represents costs
associated with our acquisition of Nabnasset in November 1997. Amortization is
recorded on a straight-line basis over a period of three years ending October
2000. Amortization of intangibles was $1.6 million for the six months ended
September 30, 1998 and 1999.

     Stock-Based Compensation. In the six months ended September 30, 1998 and
1999, we recorded deferred stock-based compensation of $238,000 and $2.7
million, relating to stock options granted to employees. Such amounts represent
the difference between the exercise price and the deemed fair value of our
common stock at the date of grant. These amounts are being amortized over the
vesting periods of the granted options. In the six months ended September 30,
1998 and 1999, we recognized stock-based compensation expense, in continuing
operations, related to options granted to employees of $60,000 and $609,000.

     Interest Expense, Net. Interest expense consists of interest expense and
other non-operating expenses. In the six months ended September 30, 1998,
interest expense included $165,000 with respect to warrants granted in
connection with notes payable to stockholders. There was no such expense
recognized during the six months ended September 30, 1999.

     DISCONTINUED OPERATIONS

     On February 26, 1999 we sold the assets of our Call Center Enterprises
division. The division was sold for $2.1 million of cash resulting in a gain on
disposal of $1.0 million. We may receive an additional payment of up to $400,000
from the sale of Call Center Enterprises based on the number of former Call
Center Enterprises employees who remain employed by the purchaser for one year
subsequent to the date of disposition. The division had a loss of $649,000 for
the six months ended September 30, 1998, which was recorded as discontinued
operations.

FISCAL 1997, 1998 AND 1999

     REVENUES

     Total Revenues. Total revenues were $13.6 million, $21.9 million and $30.3
million in fiscal 1997, 1998 and 1999, increasing 60.8%, from fiscal 1997 to
1998 and 38.5% from fiscal 1998 to 1999.


     License. License revenues were $8.4 million, $12.9 million and $17.6
million in fiscal 1997, 1998 and 1999, increasing 54.0% from fiscal 1997 to 1998
and 35.8% from fiscal 1998 to 1999. The increase in revenues from fiscal 1997 to
1998 was primarily due to an increase in our customer base as well as an
increase in sales to our existing customers. In addition, we acquired Nabnasset
in November 1997 and began realizing license revenues from our newly acquired
Quintus CTI product. The increase in license revenues from fiscal 1998 to 1999
was primarily due to a full year of CTI product sales in fiscal 1999 compared to
fewer than five months in fiscal 1998. License revenue from our CTI product
increased from $3.1 million in fiscal 1998 to $7.7 million in fiscal 1999.


     Service. Service revenues were $5.2 million, $8.9 million and $12.7 million
in fiscal 1997, 1998 and 1999, increasing 71.7% from fiscal 1997 to 1998 and
42.4% from fiscal 1998 to 1999. The

                                       26
<PAGE>   28

increase in service revenues was primarily due to growth in the installed base
of customers with maintenance agreements and maintenance renewals from products
licensed in prior periods representing $1.9 million, $4.2 million and $7.2
million for fiscal 1997, 1998 and 1999. The growth in service revenues was also
due to an increase in consulting service revenues from new and existing
customers, representing $3.3 million, $4.7 million and $5.5 million for fiscal
1997, 1998 and 1999.

     COST OF REVENUES

     License. Cost of licenses was $972,000, $708,000 and $554,000 in fiscal
1997, 1998 and 1999, representing 11.6%, 5.5% and 3.2% of license revenue in the
respective periods. The decrease was primarily due to a decrease in royalty
payments associated with the licensing of our products.

     Service. Cost of services was $4.2 million, $7.6 million and $8.6 million
for fiscal 1997, 1998 and 1999, representing 80.6%, 84.8% and 67.7% of service
revenue in the respective periods. From fiscal 1997 to 1998, the dollar increase
was primarily due to increases in professional services personnel, third-party
consulting expenses, and customer support staffing. From fiscal 1998 to 1999,
the dollar increase was primarily due to increases in professional services
personnel and third party consulting expenses. The decrease in cost of services
as a percentage of service revenues from fiscal 1998 to 1999 was primarily due
to a result of higher margins on our maintenance revenues.

     OPERATING EXPENSES

     Sales and Marketing. Sales and marketing expenses were $6.9 million, $11.3
million and $17.1 million in fiscal 1997, 1998 and 1999, representing 50.5%,
51.8% and 56.6% of total revenues in the respective periods. The increase was
primarily due to the expansion of our worldwide sales and marketing
organization, which increased from 34 employees in fiscal 1997 to 56 employees
in fiscal 1999, higher sales commissions associated with increased revenues and
increased marketing activities.

     Research and Development. Research and development expenses were $3.7
million, $5.1 million and $6.7 million in fiscal 1997, 1998 and 1999,
representing 26.9%, 23.3% and 22.2% of total revenues in the respective periods.
The dollar increases for each of the periods were primarily due to increases in
personnel, which increased from 31 employees in fiscal 1997 to 44 employees in
fiscal 1999, and related overhead costs and to a lesser extent increased
consulting expenses.

     General and Administrative. General and administrative expenses were $1.3
million, $3.2 million, and $3.6 million in fiscal 1997, 1998 and 1999,
representing 9.3%, 14.8% and 11.8% of total revenues in the respective periods.
The increase from fiscal 1997 to 1998 was primarily due to increases in
personnel, which increased from 16 employees in fiscal 1997 to 24 employees in
fiscal 1998, related overhead costs and expenses related to our infrastructure
expansion. The percentage decrease from fiscal 1998 to 1999 was primarily due to
our increased revenues.

     Amortization of Intangibles. Amortization of intangibles was $1.3 million
and $3.2 million in fiscal 1998 and 1999, representing 6.1% and 10.5% of total
revenues in the respective periods. The increase was due to a full year of
amortization in fiscal 1999 versus a partial year of amortization in fiscal
1998.

     Acquired In-Process Technologies. In November 1997, we acquired Nabnasset
for $3.5 million in cash, stock and options to purchase our common stock. The
transaction was accounted for as a purchase. In this acquisition, acquired
technology included both existing technology and in-process research and
development. The valuation of acquired technology was made by applying the
income forecast method, which considers the present value of cash flows by
product lines. Acquired

                                       27
<PAGE>   29

in-process technologies were charged to operations, as the technologies did not
have alternative future uses as of the date of the acquisition.

     Stock-Based Compensation. During fiscal 1998 and 1999 we recorded deferred
stock-based compensation of $99,000 and $1.1 million relating to stock options
granted to employees. We had no deferred stock compensation relating to stock
options granted to employees in fiscal 1997. We recorded $171,000 of stock-based
compensation expense in operating expenses in fiscal 1999. There was no
stock-based compensation expense recorded in operating expenses during fiscal
1997 or 1998.

     Interest Expense, Net. Interest expense consists of interest expense and
other non-operating expenses. During fiscal 1998 and 1999, we recognized
interest expense of $258,000 and $165,000 with respect to warrants granted in
connection with notes payable to stockholders.

     DISCONTINUED OPERATIONS

     Our Call Center Enterprises division, which was sold in February 1999, had
revenues of $2.5 million and $3.2 million for fiscal 1998 and 1999, and incurred
a loss from operations of $1.1 million and $1.9 million in fiscal 1998 and 1999.
There were no assets or liabilities remaining as of March 31, 1999. Included
within the $1.0 million gain on the sale of discontinued operations is the fair
value of options granted in connection with the sale of Call Center Enterprises
of $453,000.

     License revenues have generally increased in each of the six quarters ended
September 30, 1999, primarily due to increased market acceptance for our
products. Service revenues have also generally increased in each of these
quarters primarily due to the recognition of maintenance revenues attributable
to our growing installed base, and to a lesser extent, consulting and training
services associated with increased sales of our products. In the quarter ended
December 31, 1998 we recorded a large net loss due to our inability to close a
large number of license sales which had been forecasted to close in the quarter
coupled with an increase in operating expenses. Decreased license revenues for
the quarter were primarily due to significant turnover in our sales force during
the quarter. In addition our newly hired sales personnel, who were still gaining
experience with our products, were unable to close a large number of sales
forecasted for the quarter. In the following quarter we experienced further
turnover in our sales personnel and we implemented tighter expense controls
resulting in lower overall operating expenses.


     Our quarterly operating results have fluctuated significantly in the past,
and will continue to fluctuate in the future, as a result of a number of
factors, many of which are outside our control. As a result of our limited
operating history, we cannot forecast operating expenses based on historical
results. Accordingly, we base our anticipated level of expense in part on future
revenue projections. Most of our expenses are fixed in the short term and we may
not be able to quickly reduce spending if revenues are lower than we have
projected. Our ability to forecast our quarterly revenues accurately is limited
given our limited operating history, the length of our sales cycle and other
uncertainties in our business. If revenues in a particular quarter do not meet
projections, our net losses in a given quarter would be greater than expected.
As a result, investors should not rely on the results of one quarter as an
indication of future performance.

RECENT DEVELOPMENTS


     On September 10, 1999, we entered into an agreement to acquire Acuity, a
provider of software products to manage Internet-based customer interactions. We
expect to close this acquisition prior to the effectiveness of this offering.
The acquisition is structured as a merger in which Acuity will become our
wholly-owned subsidiary and the stockholders of Acuity will become our
stockholders. The total number of our shares to be issued in connection with the
acquisition of Acuity plus the number of shares issuable upon exercise of
options and warrants we assume in the acquisition will equal 18% of our
fully-diluted capitalization immediately following the acquisition. Based on our
outstanding capitalization as of September 30, 1999, we expect to issue
approximately 3,004,854 shares of our preferred stock and 1,546,586 shares of
our common stock. In addition, we will assume warrants to purchase approximately
323,927 shares of our common and preferred stock and options to purchase
approximately 877,955 shares of our common stock. The closing of the merger is
subject to the approval of the Acuity stockholders. The acquisition will be
accounted for using the purchase method of accounting. The aggregate purchase
price for the acquisition is approximately $45.5 million based on the value of
our capital stock to be issued and the value of the options, warrants and
liabilities to be assumed. In connection with the acquisition of Acuity, we
expect to recognize a charge for in-process technologies of approximately $3.0
million in the quarter ending December 31, 1999. Acuity is located in Austin,
Texas and had 81 employees on September 30, 1999. Acuity's revenues for the year
ended December 31, 1998 were $6.7 million, of which $5.5 million were related to
a product line that was subsequently sold in March 1999. Acuity incurred net
losses of $6.6 million, $7.7 million and $4.6 million in the years ended
December 31, 1997 and 1998 and for the nine months ended September 30, 1999.


LIQUIDITY AND CAPITAL RESOURCES


     Since May 1995, we have financed our operations primarily through the sale
of equity securities, borrowings and the sale of our products and services. As
of September 30, 1999, we have raised approximately $41.4 million, net of
offering costs, from the issuance of preferred stock. As of September 30, 1999,
we had $7.7 million in cash.


     We have a $7.5 million credit line under which $4.4 million was outstanding
as of September 30, 1999. The line had a maturity date of September 17, 1999
that was extended to December 17, 1999. Changes to the terms of the line
included a waiver to the financial covenants as well as a change of the interest
rate to prime plus 0.5% per annum. Warrants were issued to the bank to purchase
25,000 shares of Series F preferred stock at $8.25 per share. We also have a
$1.1 million term loan, of which $719,000 was outstanding as of September 30,
1999. The term loan bears interest at prime plus 2.0% per annum and is due in
monthly installments through September 2001.

     Cash used in operating activities was $2.0 million, $4.0 million, $7.3
million and $3.8 million in fiscal 1997, 1998 and 1999 and for the six months
ended September 30, 1999. Cash used in fiscal 1997 was primarily due to a net
loss of $3.5 million and an increase in accounts receivable, offset in part by
an increase in accounts payable, deferred revenues and depreciation and
amortization expenses. Cash used in fiscal 1998 was primarily due to a net loss
of $11.2 million and an increase in accounts receivable, offset in part by an
increase of deferred revenues, depreciation and amortization expenses, and a
$2.2 million non-cash charge for in-process technologies related to our
acquisition of Nabnasset. Cash used in fiscal 1999 was primarily due to a net
loss of $11.5 million and a $1.0 million gain on the disposal of discontinued
operations, offset in part by depreciation and amortization expenses. Cash used
for the six months ended September 30, 1999 was primarily due to a net loss of
$1.7 million and an increase in accounts receivable and a decrease in deferred
revenues, offset in part by an increase in depreciation and amortization and
stock based compensation.

                                       31
<PAGE>   33

     Cash used in investing activities was $1.0 million, $3.7 million and
$396,000 in fiscal 1997 and 1998 and for the six months ended September 30,
1999. Cash used in investing activities was primarily for purchases of property
and equipment in each period. In addition, cash used in fiscal 1998 included
$2.5 million for the acquisition of Nabnasset. Cash provided by investing
activities of $924,000 in fiscal 1999 was primarily due to proceeds from the
sale of discontinued operations, offset by purchases of property and equipment.

     Cash provided by financing activities was $5.2 million, $6.6 million, and
$6.2 million and $10.1 million in fiscal 1997, 1998 and 1999 and for the six
months ended September 30, 1999. Cash provided by financing activities consisted
primarily of proceeds from private sales of preferred stock and borrowings under
a bank line of credit.

     We expect to experience significant growth in our operating expenses,
particularly sales and marketing and research and development expenses, for the
foreseeable future in order to execute our business plan. As a result, we
anticipate that these operating expenses, as well as planned capital
expenditures, will constitute a material use of our cash resources. In addition,
we may utilize cash resources to fund acquisitions or investments in
complementary businesses, technologies or product lines. We believe that the net
proceeds from this offering, together with bank financing, will be sufficient to
make a required cash payment of $18.2 million to holders of some series of our
preferred stock, upon the closing of this offering, and to meet our anticipated
needs for working capital and capital expenditures for at least the next 12
months. Thereafter, we may find it necessary to obtain additional equity or debt
financing. In the event additional financing is required, we may not be able to
raise it on acceptable terms or at all.

YEAR 2000 COMPLIANCE

     The "Year 2000 Issue" refers generally to the problems that some software
may have in determining the correct century of the year. Many existing
electronic systems, including computer systems, use only the last two digits to
refer to a year. Therefore, these systems may recognize a date using "00" as
1900 rather than the year 2000. If not corrected, these electronic systems could
fail or create erroneous results when addressing dates on and after January 1,
2000.


     We have developed and are implementing a company-wide program to inventory
any systems or devices that may be affected, identify which systems or devices
are not Year 2000 compliant and remedy any Year 2000 issues that become known to
us. The scope of our Year 2000 readiness program includes the review and
evaluation of:


     - our proprietary software products;

     - the software components that we license from others and are part of the
       eContact suite of products;

     - our IT systems, such as hardware and software used in the operation of
       our business;

     - our non-IT systems or embedded technology, such as micro-controllers
       contained in various equipment and facilities; and

     - the readiness of third parties such as suppliers and other key vendors.

     We have tested our proprietary software products and determined that they
are Year 2000 compliant, when configured and used in accordance with the related
documentation, assuming that the underlying operating system of the host machine
and any other software used with or in the host machine or our products are Year
2000 compliant. Based on the results of these tests, we do not expect that
recent versions of our products will suffer Year 2000-related problems.

                                       32
<PAGE>   34

     We have made reasonable efforts to ensure that software licensed from third
parties that we incorporate into our eContact suite is Year 2000 compliant.
Despite our tests and assurances from the developers of these products, products
we sell may contain undetected errors or defects associated with Year 2000 date
functions. In most cases, we have determined that recent versions of these
licensed software components are Year 2000 compliant. In instances where our
customers are using older, non-compliant versions of these software components,
we have advised them specifically what changes they need to make in order to
make their systems Year 2000 compliant.

     We have initiated an assessment of our material internal IT systems,
including both our own software products and third party software and hardware
technology, and our non-IT systems. We have successfully upgraded and made
compliant our source code repository and our call defect tracking system. We
expect to complete testing of our material IT systems, including a comprehensive
"roll forward" simulation test by November 30, 1999, and we expect to address
any issues that arise from these tests by the second week of December. To the
extent that we are not able to test the technology provided by third-party
vendors, we are seeking assurances from these vendors that their systems are
Year 2000 compliant. We are not currently aware of any material operational
issues or potential costs associated with preparing our internal IT and non-IT
systems for the Year 2000. Because we are substantially dependent upon the
proper functioning of our computer systems, a failure of our systems to be Year
2000 compliant could materially disrupt our operations, which could seriously
harm our business.

     We do not currently have any information concerning the Year 2000
compliance status of our customers. Our current or future customers may incur
significant expenses to achieve Year 2000 compliance. If our customers are not
Year 2000 compliant, they may experience material costs to remedy problems, or
they may face litigation costs. In either case, Year 2000 issues could reduce or
eliminate the budgets that current or potential customers could have for, or
delay purchases of, our products and services. As a result, our operating
results could suffer.

     We have funded our Year 2000 readiness program from operating cash flows
and have not separately accounted for these costs. To date, these costs have not
been material. We will incur additional costs for administrative personnel to
manage our testing, review and remediation efforts, and we will incur some
expenses related to outside vendor and contractor assistance. We do not believe
these expenses will materially affect our operating results. Because we have
contracted with a third party to perform the majority of our hardware and
systems upgrades, our engineering and IT projects have not been materially
delayed.

     We have made significant efforts to ensure that our proprietary software,
the software we license from others and our internal systems are Year 2000
compliant. We believe that no serious problems will arise that will result in
significant costs. However, a reasonable "worst case" scenario might include:

     - Cash expenditures and lost person-hours. If certain functions of our
       eContact suite fail, our customers may be unable to manage their eCRM
       operations and we may be forced to spend time and money to correct these
       deficiencies.

     - Alternative use problems. We have certified the eContact software
       components, whether internally developed or licensed from others, as Year
       2000 compliant in the eCRM field of use. If any of our customers have
       adapted and are using eContact for alternative uses, they may face
       problems that we are not aware of.

     - Failure of engineering applications. While we have certified as Year 2000
       compliant our material internal systems, it is possible that some of our
       non-critical, narrow use engineering

                                       33
<PAGE>   35

       applications will experience difficulties. Although we have no reason to
       believe that these applications will fail, some areas of our engineering
       efforts could be hindered if problems arise.

     We are in the process of designing our Year 2000 contingency plan to
address situations that may result if we are unable to achieve Year 2000
readiness for our critical operations. Although it is not yet fully developed,
we expect to complete our Year 2000 contingency plan before December 31, 1999.
We do not expect the cost of developing and implementing our contingency plan to
be material. In addition, we cannot assure you that our contingency plan will
successfully address any Year 2000 problems that may arise.


     Acuity has completed its Year 2000 assessments and preparations. In
assessing its state of readiness, Acuity determined, through internal testing or
by receiving certifications from vendors, that all of its systems are generally
Year 2000 compliant. In particular, Acuity investigated the readiness of its
desktop applications and its engineering and accounting software systems. Acuity
also assessed its internal hardware and servers, as well as its telephone and
security systems. Acuity also requested that third-party providers of material
software products certify that these software products, including software
incorporated into Acuity's products, are Year 2000 compliant.



     Acuity has not tracked its Year 2000 preparedness expenses separately, and,
while it is unable to accurately estimate these expenses, it does not believe
they have had or will have a material effect on its results of operations.



     A reasonable worst case scenario for Acuity would involve a company-wide
shut down for an undeterminable period of time caused by the failure of its
network systems. Because it believes all material systems are Year 2000
compliant, Acuity has not implemented any definite contingency plans.



     Acuity determined that certain older versions of its software product are
not Year 2000 compliant. In response, Acuity has attempted to contact all
customers with noncompliant products to notify them of this lack of compliance
and to offer them the opportunity to purchase a product upgrade that is Year
2000 compliant. Following our acquisition of Acuity, we will be liable for
claims that Acuity customers have against Acuity. In addition, Acuity previously
sold an iChat product that was not Year 2000 compliant. Acuity sold its iChat
product line prior to entering an agreement to be acquired by us. We believe
that any liabilities that result from the iChat product's failure to be Year
2000 compliant will be the responsibility of the purchaser of the iChat product
line; however, third parties might still seek to assert liability against us
following our acquisition of Acuity.


RECENT ACCOUNTING PRONOUNCEMENTS

     In fiscal 1998, we adopted Statement of Financial Accounting Standards
(SFAS) No. 130, Reporting Comprehensive Income, which requires an enterprise to
report, by major components and as a single total, the change in net assets
during the period from non-owner sources. The adoption of SFAS No. 130 did not
have a material impact on our consolidated financial statements.

     In fiscal 1998, we adopted SFAS No. 131, Disclosures About Segments of an
Enterprise and Related Information, which established annual and interim
reporting standards for an enterprise's business segments and related
disclosures about its products, services and geographic areas and major
customers. The adoption of SFAS No. 131 did not have a material impact on our
consolidated financial statements.

     In fiscal 1998, we adopted Statement of Position, or SOP 97-2, Software
Revenue Recognition, and SOP 98-4, Deferral of the Effective Date of a Provision
of SOP 97-2, Software Revenue Recognition. SOP 97-2 and SOP 98-4 provide
guidance for recognizing revenue on software

                                       34
<PAGE>   36

transactions and supercede SOP 91-1. The adoption of SOP 97-2 and SOP 98-4 did
not have a material impact on our financial results.

     In March 1998, the Accounting Standards Executive Committee (AcSEC) issued
SOP 98-1, Accounting for the Costs of Computer Software Developed or Obtained
for Internal Use. SOP 98-1 establishes the accounting for costs of software
products developed or purchased for internal use, including when such costs
should be capitalized. SOP 98-1 will be effective for our fiscal year ending
March 31, 2000. We believe the adoption of this statement will not have a
significant impact on our financial position, results of operations or cash
flows.

     In April 1998, the AcSEC issued SOP 98-5, Reporting on the Costs of
Start-up Activities. Under SOP 98-5, the cost of start-up activities should be
expensed as incurred. SOP 98-1 will be effective for our fiscal year ending
March 31, 2000. We believe the adoption of this statement will not have a
significant impact on our financial position, results of operations or cash
flows.

     In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS
No. 133, Accounting for Derivative Instruments and Hedging Activities. This
statement requires companies to record derivatives on the balance sheet as
assets or liabilities, measured at fair value. Gains or losses resulting from
changes in the values of those derivatives would be accounted for depending on
the use of the derivative and whether it qualifies for hedge accounting. SFAS
No. 133 will be effective for our fiscal year ending March 31, 2001. We believe
the adoption of this statement will not have a significant impact on our
financial position, results of operations or cash flows.

INTEREST RATE RISK

     At September 30, 1999, we had an outstanding balance of $4.4 million under
a revolving line of credit with interest at prime plus 0.5% and a term loan with
an outstanding balance of $719,000 at prime plus 2.0%. A 10% movement in market
interest rates would not significantly impact our financial position or results
of operations.

                                    BUSINESS


INDUSTRY BACKGROUND


     In today's competitive global marketplace, customer service is increasingly
critical to attracting and retaining customers. Many companies are re-orienting
their businesses to be more responsive to customer needs and are focusing on
customer service and satisfaction to differentiate themselves from their
competitors. Moreover, companies are recognizing that every customer interaction
provides an opportunity to sell additional products and services, as well as
increase customer loyalty. As a result, customer service is becoming a key
competitive advantage in many industries.


     The Internet has emerged as a major medium for communication and commerce,
enabling new, highly efficient channels through which companies can engage in
commerce and interact directly with their customers. The growth of e-commerce
has increased competition for customers and reduced the importance of
traditional competitive advantages such as price, location, availability and
access. International Data Corporation estimates that the number of customers
buying goods and services over the Internet worldwide will grow from
approximately 30.8 million in 1998 to 182.6 million in 2003 and that the value
of these purchases will increase from $50.4 billion to $1.3 trillion over the
same period.


     The Internet enables companies to interact with their customers in more
ways than ever before. In addition to traditional telephone-based communication
channels, customers and companies can now interact through email, Web chat and
Web self-service. These Internet-based communication channels are growing
rapidly, creating new challenges for companies attempting to provide quality
customer service. The Gartner Group estimates that approximately 25% of all
customer interactions will take place over the Internet via email or Web
communications by 2001. Forrester Research estimates that by 2001 consumers will
send companies approximately 50 million emails per day requesting product
information or service.

     As a result of the growing use of these new communication channels,
companies are struggling to handle the volume and variety of customer
interactions. While Internet-based communications are forecast to grow
substantially, telephone-based communications will remain a critical component
of companies' customer service. Many companies are not equipped to address the
convergence of traditional and Internet-based communication channels and,
consequently, cannot offer customers the flexibility and service they demand.
Customers increasingly expect to be able to interact with companies through
whichever channel best suits their needs and are likely to use a combination of
communication channels. For example, a customer may request product literature
via email, review marketing materials or fill in an application on the Web, call
to receive more detailed information or assistance, send a signed form by fax,
and check the status of an order online. Companies' ability to provide
consistent customer service across all these communication channels will become
increasingly critical to delivering a superior customer experience.


     In many industries, Internet-based companies have captured increasing
market share and emerged as competitive threats to traditional "brick and
mortar" companies. As a result, many Global 1000 companies are under pressure to
quickly expand their online presence. These companies have typically provided
customer service through telephone-based communication channels and are now
looking to support new Internet-based communication channels. Many of these
companies have invested considerable resources to establish call centers that
manage inbound and outbound customer calls, including customer orders, inquiries
and service requests, and telesales and telemarketing operations. As these
companies move to support Internet-based communication channels and establish
customer service centers with capabilities for handling multi-channel
communications, they will seek to leverage their existing investments in call
center infrastructure and personnel. Frost and


                                       36
<PAGE>   38

Sullivan estimates that spending on Web-enabled call centers will increase from
$14.1 million in 1998 to $889.9 million in 2004.

     Similarly, many Internet-based companies that have grown rapidly and built
sizable customer bases are faced with increasingly competitive online market
environments and are looking for ways to differentiate themselves from their
competitors. These Internet-based companies have relied primarily on email and
Web self-service to interact with their customers. Many have delivered
unsatisfactory customer service. According to a recent survey of Internet sites
by Jupiter Communications, more than a third had no email address listed, took
five days or more to respond or never responded to an email.

     To date, companies have turned to several types of products to deliver
customer service. These products have primarily been point solutions targeted at
discrete communication channels. For example, computer telephony integration
software products, which automate call routing and reduce the time it takes to
respond to customer calls, are designed for telephone-based communications and
often are not able to handle or integrate with Internet-based communication
channels. Similarly, email management software products, which automate email
responses, typically are not integrated with other communication channels and
therefore do not provide a complete and accurate view of the customer. Companies
have also deployed customer relationship management applications to automate
customer interactions such as problem management and to provide a repository for
customer information. However, these applications are usually not integrated
with the underlying communication infrastructure and therefore cannot leverage
call routing or other features that enable more timely, efficient and
personalized customer service. Deploying these disparate solutions requires
significant integration and, as a result, they can be difficult and expensive to
implement and maintain.


     We believe a significant market opportunity exists for solutions that
provide both traditional "brick and mortar" companies and new Internet-based
companies with the ability to manage customer relationships across a broad range
of communication channels including the Internet, email and the telephone. This
market is referred to as the e-Customer Relationship Management or eCRM market.
eCRM solutions enable companies to:


     - manage high volumes of customer interactions;

     - support a broad range of communication channels;

     - deliver consistent and integrated customer service;


     - leverage Internet and telephone technologies; and


     - capture all relevant customer information.

THE QUINTUS SOLUTION


     We provide a comprehensive eCRM solution that enables companies to manage
customer interactions, such as customer orders, inquiries and service requests,
and deliver consistent customer service across multiple communication channels,
including the Internet, email and the telephone. Our Quintus eContact software
suite includes applications that address the needs of customer service
representatives and agents in sales and service, consumer relations, technical
support and human resources centers and a routing engine that manages customer
interactions. Our eContact software suite enables companies to personalize,
route and manage customer interactions and is designed to leverage third party
products that support email and Internet-based customer service. We recently
entered into an agreement to acquire Acuity, which will extend our ability to
provide customer service functionality through Web chat, Web self-service,
browser-based collaboration and email. Our


                                       37
<PAGE>   39


eContact suite enables companies to handle high volumes of customer
interactions, increase the efficiency of their customer service operations and
leverage opportunities to sell additional products and services to their
customers through the use of common rules for prioritizing, handling and
responding to customer interactions, shared customer profile information, and
consolidated management and reporting functions that allow companies to capture
and analyze customer information.


     We have designed Quintus eContact to be a highly scalable and flexible
solution that can be easily deployed to assist companies in reducing the costs
and improving the efficiency of their customer service operations. eContact is
based on an open, standards-based architecture and can be integrated with other
systems, enabling companies to leverage their existing customer relationship
management applications and communication infrastructure. eContact addresses the
customer service needs of large organizations as well as rapidly growing
companies that require highly functional solutions to automate and manage high
volumes of customer interactions across traditional as well as Internet-based
communication channels.


     Our eContact suite consists of several different software applications that
can be sold separately or in a group. We only recently introduced and sold the
email management and Internet-based customer service components of our eContact
suite. As a result no customer has completed the implementation of these new
components.


     The key features of the Quintus eContact solution are:

     Broad Range of Communication Channels. Quintus eContact is a comprehensive
solution that enables companies to provide sophisticated routing, tracking and
reporting capabilities across their communication infrastructure and manage
customer interactions via telephone, email, Web self-service, Web chat,
browser-based collaboration and Web callback. Our solution also supports third-
party e-commerce applications, facsimile and imaging applications, and advanced
telephony systems, such as automatic call distributors and interactive voice
response systems.

     Integrated Applications and Communication Infrastructure. Quintus eContact
integrates communication infrastructure with customer relationship management
applications. We currently sell four customer relationship management
applications that address the needs of sales and service, consumer relations,
technical support and human resources contact centers. These applications
provide out-of-the-box functionality and allow companies to accelerate the
deployment of our solution.


     Consistent Customer Service Across Communication Channels. Quintus eContact
allows companies to set business rules and personalization strategies to handle
customer interactions and deliver a consistent level of customer service across
multiple communication channels. Individual customer interactions can be managed
using transaction histories, legacy data, customer profiles and resource status
to offer a consistent and personalized level of customer service. Rules for
prioritizing, handling and responding to customer interactions and
personalization strategies can also be defined for specific communication
channels in order to leverage the attributes of each channel to provide more
targeted customer service and opportunities to sell additional products and
services to customers.



     Consolidated Customer Interaction Repository. Quintus eContact provides a
consolidated repository of information about each customer interaction
regardless of communication channel. Companies can analyze customer interactions
and determine the use and effectiveness of different channels by different
customer segments. Customer service agents can access complete customer
histories and review previous interactions. As a result, agents can respond more
effectively when, for example, a customer calls to discuss an email she received
in response to an order she previously placed online.


                                       38
<PAGE>   40


     Highly Scalable and Flexible. Quintus eContact is designed to handle
millions of customer interactions per day and support thousands of agents across
multiple customer service centers. eContact allows companies to increase the
number of customer interactions handled by customer service agents by routing
customer interactions to the best resource available, based on agent
availability and experience, as well as prior contact history. eContact is a
modular solution, providing companies with the flexibility to implement the
solution they need today and add functionality as they expand the scope of their
customer service centers. In addition, our solution is based on open standards,
enabling it to share information with existing customer relationship management
applications and legacy systems.


OUR GROWTH STRATEGY

     Our objective is to be the leading provider of eCRM software solutions that
manage customer interactions across a broad range of communication channels. Key
elements of our strategy include:

     Maintain and Extend Technology Leadership. We will continue to leverage
leading Internet and telephony technologies to enhance the performance and
functionality of our products. We believe our Quintus eContact suite is the most
comprehensive solution that enables companies to efficiently and
cost-effectively manage high volumes of customer interactions across multiple
communication channels. We plan to incorporate new technologies, such as
Internet telephony, speech recognition and digital video, into our solution as
they achieve significant market acceptance. We intend to maintain our technology
leadership through focused research and development and, potentially, through
the licensing or acquisition of complementary technologies or businesses.

     Broaden Direct and Indirect Distribution Capabilities. We intend to
continue to develop and extend our distribution capabilities. We sell our
solution through a direct sales force in North America and indirectly through 15
domestic and international resellers and distribution partners including IBM
Japan, Lucent Technologies and Logica. We plan to increase the size of our
direct sales organization and broaden our indirect distribution network with
strategic resellers and other distribution partners.

     Target Global 1000 Companies. We plan to continue to target Global 1000
companies as they rapidly transition their businesses online. We believe that
there is a significant opportunity to provide a solution that enables these
companies to leverage their existing customer service infrastructure and deliver
a consistent and integrated level of customer service across both traditional
and Internet-based communication channels. Our customers include Global 1000
companies such as Citigroup, Lucent Technologies, Procter & Gamble and United
Airlines.

     Target Leading Internet-based Companies. We plan to continue to target
leading Internet-based companies. We believe that these companies increasingly
recognize the need for higher levels of customer service in order to attract and
retain customers, and are looking for highly scalable solutions that are easy to
deploy and support both their existing Internet-based communication channels as
well as traditional communication channels. Leading Internet-based companies
that have purchased Acuity's WebCenter product line include drugstore.com,
living.com and REI.com.

     Develop and Expand Strategic Relationships. We plan to continue to develop
technology and marketing relationships with leading vendors of complementary
products in order to increase our visibility in the marketplace and broaden the
functionality of our solution. We currently have a strategic relationship with
Brightware. We also intend to expand our strategic relationships with leading
systems integrators that have significant influence over companies' purchasing
decisions. We believe that systems integrators help provide industry-specific
expertise and support our growth and

                                       39

entry into new markets. We currently have implementation relationships with
AnswerThink Consulting Group, Cambridge Technology Partners and Technology
Solutions Company.

PRODUCTS


     The Quintus eContact suite is a comprehensive eCRM solution that allows
companies to provide consistent customer service across a broad range of
communication channels, including voice, email, Web self-service, Web chat,
browser-based collaboration and Web callback. The eContact suite includes the
eContact engine, channel applications and business applications that can be sold
separately or in a group.


                                      LOGO

     The Quintus eContact suite is priced according to the product components
purchased and the number of users. Product components are typically priced from
$15,000 to $85,000 per installation, with per user prices typically ranging from
$500 to $2,300.

     QUINTUS ECONTACT ENGINE


     The Quintus eContact engine is the foundation of our eContact suite and
enables customer interactions, such as customer orders, inquiries and service
requests, to be managed consistently across multiple communication channels. Our
eContact engine, routes, tracks, and manages customer interactions, consolidates
all relevant customer information into a common data source, and provides
reporting capabilities that allow companies to capture and analyze customer
information. The eContact engine includes the following features:



     - Personalization Services. The Quintus eContact engine allows companies to
       personalize each customer interaction based on sophisticated rules for
       prioritizing, handling and responding to customer interactions that take
       into account customer profiles, transaction histories and resource
       availability. A customer interaction can be managed and routed based upon
       the communication channel, the customer or the purpose of that specific
       customer interaction. As a result, customers can receive the same level
       of service across multiple communication


                                       40
<PAGE>   42

       channels and companies can leverage the attributes of each communication
       channel to deliver more targeted and effective customer service.

     - Coordination Services. For each customer interaction, the Quintus
       eContact engine captures all relevant customer information in real time.
       By sharing customer information across systems, agents and communication
       channels, companies can provide better informed, consistent and
       synchronized customer service.

     - Consolidated Data Source and Reporting. All customer profiles and
       histories, as well as detailed records of every customer interaction
       regardless of communication channel, are stored in a common data source.
       The Quintus eContact engine provides reporting capabilities that allow
       companies to perform in-depth customer segmentation and trend analysis.


     - Centralized Customization and Administration. Companies can customize
       rules for prioritizing, handling and responding to customer interactions,
       screen layouts, Web pages, data models and data access using Quintus
       eContact's drag-and-drop graphical tools. This common toolset gives
       companies the flexibility to respond to changing business needs. Our
       eContact engine also provides centralized administration of our solution.
       Companies can control and monitor system status and availability as well
       as receive notification alerts when pre-defined thresholds are met.



     The Quintus eContact engine includes an enterprise data access layer that
provides access to relational databases as well as external data sources and
transactional systems, enabling companies to use their own business data to
manage customer interactions. Customer service agents interact with our eContact
suite through our agent console. The agent console provides an intuitive user
interface that displays customer information and pre-defined scripts, and can be
integrated with multiple applications, including front and back office systems
and legacy applications.


     QUINTUS ECONTACT CHANNEL APPLICATIONS


     Our channel applications enable companies to manage customer interactions
consistently across multiple communication channels including the Internet,
email and the telephone. Companies can deploy our channel applications
separately or as a comprehensive solution to meet their evolving needs for
customer service centers handling interactions across multiple communications
channels.

platform for integrating advanced telephony systems such as automatic call
distributors and interactive voice response systems from major
telecommunications equipment vendors. Quintus CTI allows companies to apply
sophisticated rules for prioritizing, handling and responding to customer
interactions to qualify and route telephone-based customer communications. By
integrating the telephony infrastruc-

ture with our eContact solution, Quintus CTI also enables traditional voice-only
call centers to be extended to handle Web, email and other communication
channels.

     Web Interaction. Quintus WebCenter, an Acuity product, provides a
comprehensive framework to manage Internet-based customer interactions,
including Web self-service, Web chat, browser-based collaboration and Web
callback. WebCenter enables companies to provide live customer service on the
Internet. Through Acuity's WebACD, Web-based customer interactions are routed to
the appropriate resources based on agent availability and experience. Agents can
collaborate with customers by synchronizing their browsers, seeing the Web pages
that customers are viewing and pushing new Web pages to customers to assist
them. WebCenter also allows companies to build a knowledge base of frequently
asked questions, deploy it on the Web and provide customers with full search
capabilities. With WebCenter, companies can enhance their Web sites and deliver
a more engaging and personalized customer experience by providing immediately
available online customer service options. We have not yet implemented WebCenter
as part of our eContact suite; however, WebCenter has been sold to over 100
customers and we are currently engaged in our first WebCenter and eContact
deployment. We will acquire the WebCenter and WebACD products upon the closing
of our acquisition of Acuity, which is expected to occur prior to the
effectiveness of this offering.

     Email Management. We deliver email management functionality by reselling
Brightware's software under a non-exclusive reseller agreement. Quintus Email
Management provides natural language analysis and automated response
capabilities, enabling companies to answer customers' emails accurately, cost-
effectively and rapidly. Email Management analyzes the email message content,
determines the nature of the customer request and automatically responds to the
email or forwards it with a suggested response to an agent for further review.
Responses can be automatically generated and include information provided by the
eContact data source or other external data sources.

     Electronic Commerce Connector. Quintus eCommerce Connector enables our
eContact solution to exchange information with e-commerce applications using
standard Internet protocols. Online customer transactions and purchases can be
recorded in the eContact data source and displayed to agents providing customer
service. Companies can integrate our Internet-based customer service solution
with their e-commerce applications to offer online customer assistance at the
time of purchase as well as aftersales support. In addition, our eCommerce
Connector enables companies to leverage information on customer purchasing
patterns to sell additional products or services with each customer interaction.

     QUINTUS ECONTACT BUSINESS APPLICATIONS


     We currently market four business applications that address the needs of
customer service centers for sales and service, consumer relations, technical
support and human resources. Our business applications can run separately or be
integrated with the Quintus eContact suite, can be deployed across multiple
locations and are accessed through agent desktops or via a Web browser.
Companies can easily customize data models, rules for handling customer
interactions, screen forms and Web pages to meet their specific requirements.
Our business applications can also be integrated with third-party applications
and data sources.

</TABLE>

     Prior to our acquisition of Acuity, Acuity licensed its WebCenter product
to over 100 customers.

     The following case studies illustrate how some companies are using our
products.

     PROCTER & GAMBLE

     Procter & Gamble is a leading food and consumer products company, marketing
over 300 brands in more than 140 countries.

     Business Challenge. Each year, Procter & Gamble receives high volumes of
calls and letters from consumers concerning its products and company policies.
Procter & Gamble required a solution that could integrate its telephone, letter
and facsimile interactions, and support emerging Internet communication
channels. In addition, Procter & Gamble, which has over 110,000 employees
worldwide, was looking for a solution to help manage human resources inquiries
by both current and former employees.


     Solution. Procter & Gamble licensed our Quintus CallCenter for Consumer
Relations application for its consumer relations contact centers. Procter &
Gamble is also implementing our Quintus HRQ application in its human resources
centers to handle inquiries such as health benefits, payroll and pension plans.
Procter & Gamble expects that our solution will enable it to increase the
efficiency of its call centers and improve its service to consumers and
employees by automating call center interactions, providing detailed consumer
and employee information, and tracking problem resolution to completion.


     CITIGROUP

     Citigroup is a leading global financial services company, providing over
100 million consumers, corporations, governments and institutions in more than
100 countries with a broad range of financial products and services.

     Business Challenge. Citigroup relies on multiple call centers and thousands
of agents to provide financial services to customers over the telephone.
Citigroup needed to integrate its call center telephony systems with its
back-office systems to enable agents to access detailed customer information and
perform additional business functions. In addition, Citigroup required a
flexible and scalable solution that could be deployed across multiple call
centers. Citigroup was also looking for a

                                       44
<PAGE>   46

solution that could be implemented in conjunction with its "e-Citi" initiative
to increase its presence on the Internet and deliver financial services online.

     Solution. Citigroup is currently using our Quintus CTI product to integrate
its telephony systems and enable approximately 1,000 agents across multiple call
centers to deliver superior customer service. Our solution enables Citigroup to
handle service requests quickly and cost-effectively by providing agents with
detailed customer information and routing calls to the most appropriate agent.
Citigroup has also deployed our Quintus CustomerQ application integrated with
our Quintus CTI product as part of its e-Citi projects. In addition to
increasing customer satisfaction by enabling e-Citi agents to track customer
relationships and activities, our solution is designed to increase revenue by
alerting agents to likely cross-selling and up-selling opportunities.

     TICKETMASTER

     Ticketmaster is a leading provider of automated ticketing distribution
services, selling approximately 70 million tickets worldwide in 1998.

     Business Challenge. Ticketmaster sells tickets to the public through the
telephone, the Internet and retail outlets. More recently, Ticketmaster has
started selling a greater percentage of tickets over the Internet. Through the
Internet, Ticketmaster allows customers to find information about upcoming
events and purchase tickets and other related merchandise. To support its
growing online sales and customer service needs, Ticketmaster sought a more
comprehensive solution that would enable it to provide a higher level of
customer service through automated email, Web chat, Web callback and
collaborative browsing. Ticketmaster wanted to be able to integrate this
solution with its existing call centers and telephone systems.

     Solution. Ticketmaster selected our Quintus eContact suite earlier this
year. Ticketmaster expects that our solution, which is being developed, will
enable it to provide live customer support through Web chat and browser-based
collaboration, and to respond more efficiently to large volumes of emails.
Ticketmaster plans to integrate our solution within its call centers as its need
for Internet customer service increases.

     ASHFORD.COM

     Ashford.com is an online retailer of luxury and premium products, selling
more than 150 brands and 8,000 different styles of new and vintage watches,
fragrances, leather accessories, sunglasses and writing instruments.

     Business Challenge. As a provider of luxury and premium products,
Ashford.com targets a customer group that expects a high level of customer
service. Ashford.com wanted to be able to communicate directly with its online
customers as they navigate its Web site in order to increase sales and provide
an enhanced online shopping experience.

     Solution. Ashford.com deployed Acuity's WebCenter product to provide
interactive sales, service and support to customers on its Web site. WebCenter
enables Ashford.com to deliver live online assistance to its customers while
they are browsing the Web site. Customers can remain online and have one-on-one
chat sessions with customer service agents. WebCenter also allows an agent to
display Web pages on a customer's screen in real-time in order to provide
additional support. For example, an agent could help a customer fill in a
purchase form or guide a customer through the site in order to view specific
products. In addition, using WebCenter, Ashford.com can connect each customer to
the most appropriate agent, matching a customer's inquiry with an agent's area
of expertise. Since implementing WebCenter, Ashford.com has noted that customers
using its live

                                       45
<PAGE>   47

customer service capabilities are more likely to make a purchase and experience
higher levels of customer satisfaction.

     REI.COM

     REI.com is the online division of Recreational Equipment Incorporated
(REI), a national retailer of outdoor gear and clothing.

     Business Challenge. As an online retailer, REI.com depends on customers
making purchases through its Web site. REI.com found that many potential
customers on its Web site abandoned their shopping carts before completing a
purchase. In order to increase sales REI.com wanted to create a more engaging
online experience and enable customers to interact directly with its customer
service agents while navigating its Web site.

     Solution. REI.com deployed Acuity's WebCenter product to provide customer
service on its Web site. WebCenter allows customers to easily find answers to
commonly asked questions by querying an online knowledge base and to receive
assistance through email or by connecting to a live customer service agent
through Web chat. Customers are also able to request that an agent call them
back. REI is currently offering live online customer assistance during peak
hours and is looking to extend it in the future. By providing live customer
support during the sales process, REI.com expects to increase the number of
potential customers that make a purchase, as well as the overall level of
customer satisfaction and loyalty.

TECHNOLOGY

     Quintus eContact is based on a scalable, multi-tiered architecture. Our
eContact product suite enables eCRM features through a sequence of cooperating,
distributed software servers that perform a variety of functions, including
creating and manipulating data containers, routing customer contacts, allowing
agents to access data and interact with customers through a Web browser. Our
multi-platform solution runs on all major UNIX and Windows NT operating systems.

     Electronic Data Container. When a customer contacts a company, whether by
telephone, fax, email or through a Web site, an electronic data container for
that customer interaction is created. Existing customer information can be
retrieved from the data repository to populate the data container, or new
information can be obtained directly from the customer. The data container
continually collects information throughout the lifecycle of the customer
interaction and can be routed throughout an enterprise, carrying detailed
information about the customer, including the customer's history with the
company and details of this particular customer interaction. If the customer is
transferred to another agent at another site or to an agent using a different
communication channel, the data container accompanies the transition, ensuring
that the customer perceives a seamless service process.

     Enterprise Data Access Layer. Quintus eContact includes an enterprise data
access layer that provides access to relational and legacy data sources. The
enterprise data access layer creates a uniform view of third party data
regardless of the data source and allows eContact to incorporate third-party
customer information.

     Abstraction and Customization. Quintus eContact uses a data abstraction
layer that allows companies to store data entities, business rules and screen
layouts as business objects. Customizations are performed on the business
objects to modify them. All changes to the business objects are automatically
reflected throughout our eContact suite.

                                       46
<PAGE>   48

     Workflow and Routing Engine. Quintus eContact provides a graphical tool to
create and modify customer interaction flows, define routing rules and build
agent scripts. These customer interaction flows, rules and scripts are
specified, distributed and stored in Extensible Markup Language, allowing
eContact to leverage industry-standard tools and technologies. Customer
interaction flows are defined using re-usable building blocks that can be used
to create new routing rules as companies' needs evolve.


     High Availability. We have built our system using a modular,
component-based approach. Additional customer service center capabilities and
applications can be introduced without requiring companies to change their
computing infrastructure and, in most cases, without affecting their operations.
Our system also provides multiple redundant configurations, delivering the
ability to "failover" to an alternative configuration in the event of a system
failure.


CUSTOMER SUPPORT SERVICES

     We believe that high quality services and support are critical requirements
for continued growth and increased sales of our products. We have made and
expect to continue to make significant investments to increase our ability to
service and support our customers.

     Our customer support services organization is organized into four groups
including customer service management, professional services, technical support
and education services.

     Customer Service Management. Our customer service management team handles
many aspects of our customer relationships including answering general
questions, renewing maintenance agreements, shipping product upgrades and
coordinating with our other resources to meet customer needs.

     Professional Services. Our professional services group helps facilitate the
implementation of our solution. We provide systems integration services to
support our entire product suite. Our services include integration,
customization, data modeling, project management and business rules development.
The professional services group also provides support for our implementation
partners.

     Technical Support. Our technical services group is dedicated to providing
the highest level of support to our customers. We currently operate three
technical support centers in the United States and rely upon a network of
service providers internationally to provide consultations via toll-free
telephone, email and the Web. Additionally, customers have 24-hour access to our
online knowledge repository and the ability to directly log and track their
issues through our Web site. We offer a tiered maintenance and support program.
Customers can choose from our existing support packages or have a custom package
developed to meet their particular needs including 24x7 coverage and other
assistance options.

     Education Services. Our education services group offers a full spectrum of
classes providing the training needed to understand, implement and use our
solution. We offer lectures and teaching labs to end-users, administrators,
developers and system integration partners at our facilities in California and
Massachusetts. Upon request, we can also provide customized on-site training.

SALES AND MARKETING

     Sales. We sell our products through a direct sales force and indirectly
through resellers and distribution partners. To date, we have targeted our sales
efforts at Global 1000 companies and other rapidly growing companies pursuing
eCRM initiatives, including those in the financial services, telecommunications
and consumer products industries. Our sales force consists primarily of sales
people and sales engineers located in our sales offices in numerous locations
across the United States.

                                       47
<PAGE>   49

We also maintain international offices in Amsterdam and London from which we
provide sales support to our international distribution partners.

     We currently have relationships with 15 domestic and international reseller
and distribution partners including IBM Japan, Lucent Technologies and Logica.
We also enhance our sales efforts through strategic relationships with systems
integrators such as AnswerThink Consulting Group, Cambridge Technology Partners
and Technology Solutions Company. We intend to continue to expand our sales
efforts by increasing the size of our direct sales force and broadening our
indirect distribution channels.

     Marketing. Our marketing efforts focus on creating market awareness for
eCRM solutions, promoting our products and services, and generating sales
opportunities. We have a comprehensive marketing strategy that includes print
advertising, public relations campaigns, direct mailings, newsletters, industry
events including trade shows, analyst programs and speaking engagements, and
joint marketing arrangements. We also advertise on the Internet and use our Web
site to enhance our market presence and generate additional leads.

RESEARCH AND DEVELOPMENT

     Our research and development efforts are focused primarily around enhancing
our core technology and developing additional applications for the Quintus
eContact suite. We operate development centers in California, Massachusetts and,
following the acquisition of Acuity, Texas. Our software development approach
consists of a well-defined methodology that provides guidelines for planning,
controlling and implementing projects. This approach uses a cross-functional,
team-based development and release process. Our research and development group
works closely with customers, partners, our sales and marketing group and senior
management to assist in defining product direction and to ensure that products
are brought to market successfully. Members of our research and development
group have extensive experience in customer relationship management software as
well as Internet and telephony communication technologies.

     Our research and development expenditures were approximately $3.7 million,
$5.1 million, $6.7 million and $4.0 million in fiscal 1997, 1998 and 1999 and
for the six months ended September 30, 1999. We believe that our future
performance will depend in large part on our ability to enhance our current
product line, develop new products and maintain our technological
competitiveness. As a result, we intend to continue to expend significant
resources in research and development.

COMPETITION

     We currently face competition primarily from customer relationship
management software vendors such as Siebel Systems and Clarify, emerging
Internet customer interaction software vendors such as Kana Communications and
WebLine Communications, and computer telephony software vendors such as Genesys
Telecommunications Laboratories. Because there are relatively low barriers to
entry in the software market, we expect additional competition from other
established and emerging companies. Potential future competitors include
traditional call center technology providers and large enterprise application
vendors as well as independent systems integrators, consulting firms and
in-house information technology departments that may develop solutions that
compete with our products. We may not be able to compete effectively in the
future as current competitors expand their product offerings and new companies
enter the rapidly evolving eCRM market.

     Many of our current and potential competitors have longer operating
histories, significantly greater financial, technical, sales, marketing and
other resources, greater name recognition and a

                                       48
<PAGE>   50

larger installed base of customers than we do. As a result, these competitors
can devote greater resources to the development, promotion and sale of products
than we can and may be able to respond to new or emerging technologies and
changes in customer requirements more quickly than we can.

     Current and potential competitors have established and may in the future
establish relationships among themselves or with third parties to increase the
ability of their products to address the needs of our current or prospective
customers. In addition, a number of companies with significantly greater
resources than ours could attempt to increase their presence in the eCRM market
by acquiring or forming strategic alliances with our competitors. As a result,
it is likely that new competitors or alliances among competitors will emerge and
may rapidly acquire significant market share. Recently, a number of our
competitors have been acquired by significantly larger companies, creating a
number of stronger competitors with greater resources than ours. Cisco Systems
acquired GeoTel Communications in June 1999 and entered into an agreement to
acquire WebLine Communications in September 1999. These acquisitions strengthen
Cisco's position as a provider of call routing and Web chat software. In
September 1999, Alcatel entered into an agreement to acquire Genesys
Telecommunications Laboratories, adding Genesys' computer telephony software
functionality to its voice and data network capabilities. More recently, in
October 1999, PeopleSoft entered into an agreement to acquire The Vantive
Corporation, a provider of customer relationship management software. In
addition, in October 1999, Nortel entered into an agreement to acquire Clarify,
a provider of customer relationship management software.

     We cannot assure you that we will be able to compete successfully against
current and future competitors. Increased competition is likely to result in
price reductions, reduced margins and loss of market share, any of which could
harm our business, financial condition and results of operations. In order to be
successful in the future, we must respond promptly and effectively to
technological change, changing customer requirements and competitors'
innovations. The introduction of new products by competitors or shifts in market
demands could render our existing products obsolete.

PATENTS AND PROPRIETARY RIGHTS

     Our success and competitiveness are dependent to a significant degree on
the protection of our proprietary technology. We rely primarily on a combination
of copyrights, trademarks, licenses, trade secret laws and restrictions on
disclosure to protect our intellectual property and proprietary rights. We also
enter into confidentiality agreements with our employees and consultants, and
generally control access to and distribution of our documentation and other
proprietary information. Despite these precautions, others may be able to copy
or reverse engineer aspects of our products, to obtain and use information that
we regard as proprietary or to independently develop similar technology. Any
such actions by competitors could harm our business, operating results and
financial condition.

     In addition, the laws of some foreign countries may not protect our
proprietary rights to the same extent as the laws of the United States, and
effective patent, copyright, trademark and trade secret protection may not be
available in these jurisdictions.

     We may need to take legal action in the future to enforce or defend our
intellectual property and proprietary rights, to protect our trade secrets or to
determine the validity and scope of the intellectual property and proprietary
rights of others. Litigation, whether successful or unsuccessful, could result
in substantial costs and diversion of management and technical resources, either
of which could harm our business, operating results and financial condition.

     We attempt to avoid infringing upon known intellectual property and
proprietary rights of third parties in our product development efforts. However,
we have not conducted and do not plan to

                                       49
<PAGE>   51

conduct comprehensive patent searches to determine whether the technology used
in our products infringes patents held by others. In addition, product
development is inherently uncertain in a rapidly evolving technological
environment in which there may be numerous patent applications pending, many of
which are confidential when filed, with regard to similar technologies. If our
products were to violate the proprietary rights of others, we may be liable for
substantial damages. In addition, we may be required to reengineer our products
or seek to obtain licenses to continue offering our products. We cannot assure
you that such efforts would be successful.

EMPLOYEES

     As of September 30, 1999, we had a total of 208 employees, including 54
people in research and development, 81 people in sales and marketing, 44 people
in customer support services and 29 people in general and administrative
services. We do not have a collective bargaining agreement with any of our
employees and we consider our employee relations to be good. As of September 30,
1999, Acuity had a total of 81 employees.

FACILITIES

     Our principal administrative, sales, marketing, support and research and
development facilities are located in approximately 36,000 square feet of space
in Fremont, California. Our lease of approximately 30,000 square feet expires in
December 2000, and our lease of approximately 6,000 square feet expires in April
2001. We lease several office suites in the United States and the United Kingdom
for sales and service personnel. In addition, we maintain offices in Acton,
Massachusetts and have our European headquarters in Amsterdam, the Netherlands.
Upon the closing of our acquisition of Acuity, we will assume a lease for
approximately 22,000 square feet in Austin, Texas, expiring in June 2000.

BOARD COMMITTEES

     The board of directors has a compensation committee and an audit committee.

     Compensation Committee. The compensation committee of the board of
directors reviews and makes recommendations to the board regarding all forms of
compensation provided to our executive officers and directors, including stock
compensation and loans. In addition, the compensation committee reviews and
approves stock compensation arrangements for all of our employees and
administers our 1999 Stock Incentive Plan, Employee Stock Purchase Plan and 1999
Director Option Plan. The board of directors has established a stock option
committee whose sole member is the chairman of the board of directors, Alan
Anderson. The stock option committee has the power to approve grants of stock
options under our 1999 Stock Incentive Plan to individuals who are neither
officers nor board members not exceeding 20,000 shares per grant. The current
members of the compensation committee are Messrs. Bartlett and Herman.

     Audit Committee. The audit committee of the board of directors reviews and
monitors our corporate financial reporting and our internal and external audits,
including, among other things, our internal audit and control functions, the
results and scope of the annual audit and other services provided by our
independent auditors and our compliance with legal matters that have a
significant impact on our financial reports. The audit committee also consults
with our management and our independent auditors prior to the presentation of
financial statements to stockholders and, as appropriate, initiates inquiries
into aspects of our financial affairs. In addition, the audit committee has the
responsibility to consider and recommend the appointment of, and to review fee
arrangements with, our independent auditors. The current members of the audit
committee are Ms. Wohlers and Messrs. Harman and Rosen.

DIRECTOR COMPENSATION

     Directors do not receive any cash fees for their service on the board or
any board committee, but they are entitled to reimbursement for all reasonable
out-of-pocket expenses incurred in connection with their attendance at board and
board committee meetings. From time to time, certain directors who are not
employees of Quintus have received grants of options to purchase shares of our
common stock. Following this offering, directors will receive automatic option
grants under our 1999 Director Option Plan. If a change in control of Quintus
occurs, a non-employee director's option granted under our 1999 Director Option
Plan will become fully vested. See "Stock Plans -- 1999 Director Option Plan."

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The compensation committee of the board of directors currently consists of
Messrs. Bartlett and Herman. No interlocking relationship exists between any
member of our board of directors or our compensation committee and any member of
the board of directors or compensation committee of any other company, and no
such interlocking relationship has existed in the past.

<PAGE>   56

INDEMNIFICATION

     In September 1999, the board of directors authorized Quintus to enter into
indemnification agreements with each of our directors and executive officers.
The form of indemnification agreement provides that we will indemnify our
directors and executive officers against any and all of their expenses incurred
by reason of their status as a director or executive officer to the fullest
extent permitted by Delaware law and our bylaws.

     Our certificate of incorporation and bylaws each contain certain provisions
relating to the limitation of liability and indemnification of our directors and
officers. Our certificate of incorporation provides that our directors will not
be personally liable to Quintus or our stockholders for monetary damages for any
breach of fiduciary duty as a director, except for liability

     - for any breach of the director's duty of loyalty to Quintus or our
       stockholders;

     - for acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;

     - in connection with unlawful payments of dividends or unlawful stock
       repurchases or redemptions as provided in Section 174 of the Delaware
       General Corporation Law; or

     - for any transaction from which the director derives any improper personal
       benefit.

     Our certificate of incorporation also provides that if the Delaware General
Corporation Law is amended after the approval by our stockholders of our
certificate of incorporation to authorize corporate action further eliminating
or limiting the personal liability of directors, then the liability of our
directors will be eliminated or limited to the fullest extent permitted by the
Delaware General Corporation Law. These provisions are not intended to limit the
liability of our directors or officers for any violation of applicable federal
securities laws.

     In addition, as permitted by Section 145 of the Delaware General
Corporation Law, our bylaws provide that

     - we are required to indemnify our directors and executive officers to the
       fullest extent permitted by the Delaware General Corporation Law;

     - we may, in our discretion, indemnify other of our officers, employees and
       agents as provided by the Delaware General Corporation Law;

     - with some exceptions, we are required to advance all expenses incurred by
       our directors and executive officers in connection with a legal
       proceeding;

     - the rights conferred in the bylaws are not exclusive;

     - we are authorized to enter into indemnification agreements with our
       directors, officers, employees and agents; and

     - we may not retroactively amend our bylaw provisions relating to
       indemnification.

OPTION GRANTS IN LAST FISCAL YEAR

     The table below sets forth each grant of stock options during the fiscal
year ended March 31, 1999 to each of the Named Executive Officers. We granted a
total of 1,205,612 options to our employees during fiscal 1999. No stock
appreciation rights were granted to these individuals during this period.

     Each of the options listed in the table below is immediately exercisable
except to the extent exercisability was deferred to preserve incentive stock
option tax benefits. The shares purchasable upon exercise of these options may
be repurchased by us at the original exercise price paid per share upon the
optionee's cessation of service prior to vesting in such shares. Other than Ms.
Salvesen's option for 10,000 shares, the repurchase right lapses and the
optionee vests in 25% of the option shares upon completion of one year of
service from the date of grant and the balance in a series of equal monthly
installments over the next 36 months of service. Ms. Salvesen's option for
10,000 shares vests in equal monthly installments over a two-year period. Each
of the option shares listed in the table will vest upon an acquisition of
Quintus by merger or asset purchase, unless our repurchase right in connection
with unvested option shares is transferred to the acquiring entity. Each of the
options has a ten-year term, but may be terminated earlier if the optionee
ceases to remain with us.

     The exercise prices of the options we grant are equal to the fair market
value of our common stock, as valued by our board of directors, on the date of
grant. The exercise price may be paid in cash, in shares of our common stock
valued at fair market value on the exercise date or through a cashless exercise
procedure involving a same-day sale of the purchased shares. We may also finance
the option exercise by loaning the optionee sufficient funds to pay the exercise
price for the purchased shares, together with any federal and state income tax
liability incurred by the optionee in connection with such exercise.

     The potential realizable values at 5% and 10% appreciation are calculated
by assuming a base price of $13.00 per share that appreciates at the indicated
rate for the entire ten-year term of the option and that the option is exercised
at the exercise price and sold on the last day of its term at the

                                       56
<PAGE>   58

appreciated price. Stock price appreciation rates of 5% and 10% are assumed
pursuant to rules promulgated by the Securities and Exchange Commission and do
not represent our prediction of our stock price performance.

AGGREGATE OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION VALUES

     The table below sets forth for each of the Named Executive Officers, the
number of options exercised during the fiscal year ended March 31, 1999 and the
number and value of securities underlying unexercised options that were held by
the Named Executive Officers as of March 31, 1999. No stock appreciation rights
were exercised by the Named Executive Officers in fiscal year 1999, and no stock
appreciation rights were outstanding at the end of that year.

     The amounts in the "Value Realized" column are equal to the fair market
value of the purchased shares on the option exercise date, less the exercise
price paid for such shares.

     Options granted under our 1995 Stock Option Plan are immediately
exercisable for all the option shares, but any shares purchased under those
options may be repurchased by us, at the original exercise price paid per share,
if the optionee ceases to remain with us prior to the vesting in his or her
shares. The headings "Vested" refer to shares we may no longer repurchase; the
headings "Unvested" refer to shares we had rights to repurchase as of March 31,
1999.

     The amounts in the "Value of Unexercised in-the-Money Options at March 31,
1999" column are based on $1.75 per share, the fair market value of our common
stock at the end of fiscal 1999, less the exercise price payable for such
shares.

EMPLOYMENT AND CHANGE OF CONTROL AGREEMENTS

     The compensation committee, as plan administrator of the 1999 Stock
Incentive Plan, has the authority to accelerate the vesting of the shares of
common stock subject to outstanding options held

                                       57
<PAGE>   59

by the Named Executive Officers and any other person in connection with certain
changes in control of Quintus. In connection with our adoption of the 1999 Stock
Incentive Plan, we have provided that upon a change in control of Quintus, each
outstanding option and all shares of restricted stock will generally become
fully vested unless the surviving corporation assumes the option or award or
replaces it with a comparable award.

     Except for Mr. Anderson and Mr. Burke, none of the Named Executive Officers
has employment agreements with us, and his or her employment may be terminated
at any time. We have entered into an agreement with Mr. Anderson, our Chief
Executive Officer, dated May 23, 1995, which provides for payment of severance
pay in the amount of nine months base salary in the event that his employment is
involuntarily terminated without cause. In May 1995, we granted Mr. Anderson
unvested options to purchase 1,142,858 shares of common stock. Subsequently, Mr.
Anderson exercised his option to purchase all of these options subject to our
right to repurchase his unvested shares should he cease his service with us. As
of September 1999, Mr. Anderson had fully vested in 671,429 of these shares.
Provided that Mr. Anderson remains in our service, the remaining 471,429 shares
of unvested common stock will vest as follows: 117,857 will vest in equal annual
installments beginning in May 2000. However, these 471,429 shares of unvested
common stock could vest in full if following this offering the per share value
of our common stock reaches specified targets as measured on May 25, 2000, 2001
or 2002. Mr. Anderson's agreement also provides that these 471,429 shares of
unvested common stock will vest in full following certain changes in control of
Quintus.

     We have entered into an agreement with Mr. Burke, our President, dated June
11, 1999, which provides for payment of severance in the amount of 3 months base
salary in the event that his employment is involuntarily terminated without
cause before July 5, 2000. In addition, Mr. Burke has been granted unvested
options to purchase 685,000 shares of common stock. Of these 685,000 options,
411,000 will vest as follows: 205,000 will vest upon completion of one year of
service from the date of grant and the balance will vest in equal monthly
installments over the next 36 months of service thereafter. 274,000 of these
685,000 options will vest within three to five years, depending on Quintus'
achievement of specified license and revenue targets. Mr. Burke's agreement also
provides for accelerated vesting of up to half of his 685,000 options if his
employment is involuntarily terminated without cause within six months following
certain changes in control of Quintus and he is then vested in less than half of
such options.

STOCK PLANS

     1999 STOCK INCENTIVE PLAN

     Share Reserve. Our board of directors adopted our 1999 Stock Incentive Plan
in September 1999 to be effective simultaneously with this offering. We will
seek the approval of this plan by our stockholders. We have reserved 1,000,000
shares of our common stock for issuance under the 1999 Stock Incentive Plan. Any
shares not yet issued under our 1995 Stock Option Plan on the date of this
offering will also be available under the 1999 Stock Incentive Plan. On January
1 of each year, starting with the year 2000, the number of shares in the reserve
will automatically increase by 5% of the total number of shares of common stock
that are outstanding at that time or, if less, by 2,000,000 shares. In general,
if options or shares awarded under the 1999 Stock Incentive Plan or the 1995
Stock Option Plan are forfeited, then those options or shares will again become
available for awards under the 1999 Stock Incentive Plan. We have not yet
granted any options under the 1999 Stock Incentive Plan.

     Outstanding options under the 1995 Stock Option Plan will be incorporated
into the 1999 Stock Incentive Plan at the time of this offering and no further
option grants will be made under the 1995

                                       58
<PAGE>   60

Stock Option Plan. The incorporated options will continue to be governed by
their existing terms, unless the Board elects to extend one or more features of
the 1999 Stock Incentive Plan to those options or to other outstanding shares.
Previously, options granted under the 1995 Stock Option Plan provided that
vesting of the shares would accelerate upon an acquisition only if not assumed
by the acquiring entity.

     Administration. The compensation committee of our board of directors
administers the 1999 Stock Incentive Plan. The committee has the complete
discretion to make all decisions relating to the interpretation and operation of
our 1999 Stock Incentive Plan. The committee has the discretion to determine who
will receive an award, what type of award it will be, how many shares will be
covered by the award, what the vesting requirements will be, if any, and what
the other features and conditions of each award will be. The compensation
committee may also reprice outstanding options and modify outstanding awards in
other ways.

     Eligibility. Employees, consultants and members of our board of directors
who are not employees are eligible to participate in the 1999 Stock Incentive
Plan.

     Types of Award. The 1999 Stock Incentive Plan provides for the award of
incentive or nonstatutory options to purchase shares of our common stock,
restricted shares of our common stock, stock appreciation rights and stock
units.

     Options. An optionee who exercises an incentive stock option may qualify
for favorable tax treatment under Section 422 of the Internal Revenue Code of
1986. On the other hand, nonstatutory stock options do not qualify for such
favorable tax treatment. The exercise price for incentive stock options granted
under the 1999 Stock Incentive Plan may not be less than 100% of the fair market
value of our common stock on the option grant date. In the case of nonstatutory
stock options, the minimum exercise price is 85% of the fair market value of our
common stock on the option grant date. Optionees may pay the exercise price by
using:

     - cash;

     - shares of common stock that the optionee already owns;

     - a full-recourse promissory note, except that the par value of newly
       issued shares must be paid in cash;

     - an immediate sale of the option shares through a broker designated by us;
       or

     - a loan from a broker designated by us, secured by the option shares.

     Options vest at the time or times determined by the compensation committee.
In most cases, our options vest over a four-year period following the date of
grant. Options generally expire ten years after they are granted, except that
they generally expire earlier if the optionee's service terminates earlier. The
1999 Stock Incentive Plan provides that no participant may receive options
covering more than 1,000,000 shares in the same year, except that a newly hired
employee may receive options covering up to 2,000,000 shares in the first year
of employment.

     Stock Appreciation Rights. A participant who exercises a stock appreciation
right shall receive the increase in value of our common stock over the base
price. The base price for stock appreciation rights granted under the 1999 Stock
Incentive Plan shall be determined by the compensation committee. The settlement
value of the stock appreciation right may be paid in cash or shares of common
stock.

     Stock appreciation rights vest at the time or times determined by the
compensation committee. In most cases, our stock appreciation rights vest over a
four-year period following the date of grant. Stock appreciation rights
generally expire 10 years after they are granted, except that they generally

                                       59
<PAGE>   61

expire earlier if the participant's service terminates earlier. The 1999 Stock
Incentive Plan provides that no participant may receive stock appreciation
rights covering more than 1,000,000 shares in the same year, except that a newly
hired employee may receive stock appreciation rights covering up to 2,000,000
shares in the first year of employment.

     Restricted Shares. Restricted shares vest at the time or times determined
by the compensation committee and may be awarded under the 1999 Stock Incentive
Plan in return for:

     - cash;

     - a full-recourse promissory note, except that the par value of newly
       issued shares must be paid in cash;

     - services already provided to us; and

     - in the case of treasury shares only, services to be provided to us in the
       future.

     Stock units. Stock units vest at the time or times determined by the
compensation committee and may be awarded under the 1999 Stock Incentive Plan in
return for:

     - cash;

     - a full-recourse promissory note, except that the par value of newly
       issued shares must be paid in cash;

     - services already provided to us; and

     - in the case of treasury shares only, services to be provided to us in the
       future.

     Change in Control. If a change in control of Quintus occurs, an option or
restricted stock award under the 1999 Stock Incentive Plan will generally become
fully vested. However, if the surviving corporation assumes the option or award
or replaces it with a comparable award, then vesting shall generally not
accelerate. A change in control includes:

     - a merger of Quintus after which our own stockholders own 50% or less of
       the surviving corporation or its parent company;

     - a sale of all or substantially all of our assets;

     - the replacement of more than one-half of our directors over a 24-month
       period; or

     - an acquisition of 50% or more of our outstanding stock by any person or
       group, other than a person related to Quintus such as a holding company
       owned by our stockholders.

     Amendments or Termination. Our board may amend or terminate the 1999 Stock
Incentive Plan at any time. If our board amends the plan, it does not need to
ask for stockholder approval of the amendment unless applicable law requires it.
The 1999 Stock Incentive Plan will continue in effect indefinitely, unless the
board decides to terminate the plan earlier.

     EMPLOYEE STOCK PURCHASE PLAN

     Share Reserve and Administration. Our board of directors adopted our
Employee Stock Purchase Plan on September 9, 1999. We will seek the approval of
this plan by our stockholders. Our Employee Stock Purchase Plan is intended to
qualify under Section 423 of the Internal Revenue Code and will become effective
simultaneously with this offering. We have reserved 1,000,000 shares of our
common stock for issuance under the plan. On May 1 of each year, starting with
the year 2000, the number of shares in the reserve will automatically be
increased by 2% of the total number of shares of our common stock that are
outstanding at that time or, if less, by 1,000,000 shares. The plan will be
administered by a committee of our board of directors.

                                       60
<PAGE>   62

     Eligibility. All of our employees are eligible to participate if they are
employed by us for more than 20 hours per week and for more than five months per
year. Eligible employees may begin participating in the plan at the start of any
offering period. Each offering period lasts 24 months. Overlapping offering
periods start on May 1 and November 1 of each year. However, the first offering
period will start on the effective date of this offering and end on October 31,
2001.

     Amount of Contributions. Our Employee Stock Purchase Plan permits each
eligible employee to purchase common stock through payroll deductions. Each
employee's payroll deductions may not exceed 15% of the employee's cash
compensation. Purchases of our common stock will occur on April 30 and October
31 of each year. Each participant may purchase up to 2,000 shares on any
purchase date. However, the value of the shares purchased in any calendar year,
measured as of the beginning of the applicable offering period, may not exceed
$25,000.

     Purchase Price. The price of each share of common stock purchased under our
Employee Stock Purchase Plan will be 85% of the lower of the fair market value
per share of common stock on the date immediately before the first day of the
applicable offering period, or the fair market value per share of common stock
on the purchase date. In the case of the first offering period, the price per
share under the plan will be 85% of the lower of the price per share to the
public in this offering, or the fair market value per share of common stock on
the purchase date.

     Other Provisions. Employees may end their participation in the Employee
Stock Purchase Plan at any time. Participation ends automatically upon
termination of employment with Quintus. If a change in control of Quintus
occurs, our Employee Stock Purchase Plan will end and shares will be purchased
with the payroll deductions accumulated to date by participating employees,
unless the plan is assumed by the surviving corporation or its parent. Our board
of directors may amend or terminate the Employee Stock Purchase Plan at any
time. Our chief executive officer may also amend the plan in certain respects.
If our board increases the number of shares of common stock reserved for
issuance under the plan, except for the automatic increases described above, it
must seek the approval of our stockholders.

     1999 DIRECTOR OPTION PLAN

     Share Reserve. Our board of directors adopted our 1999 Director Option Plan
on September 9, 1999. We will seek the approval of this plan by our
stockholders. We have reserved 500,000 shares of our common stock for issuance
under the plan. In general, if options granted under the 1999 Director Option
Plan are forfeited, then those options will again become available for grants
under the plan. The Director Option Plan will be administered by the
compensation committee of our board of directors, although all grants under the
plan are automatic and non-discretionary.

     Initial Grants. Only the non-employee members of our board of directors
will be eligible for option grants under the 1999 Director Option Plan. Each
non-employee director who first joins our board after the effective date of this
offering will receive an initial option for 30,000 shares. That grant will occur
when the director takes office. The initial options vest in monthly installments
over the two-year period following the date of grant.

     Annual Grants. At the time of each of our annual stockholders' meetings,
beginning in 2000, each non-employee director who will continue to be a director
after that meeting will automatically be granted an annual option for 10,000
shares of our common stock. However, a new non-employee director who is
receiving the 30,000-share initial option will not receive the annual option in
the same calendar year. The annual options are fully vested on the first
anniversary of the date of grant.

     Other Option Terms. The exercise price of each non-employee director's
option will be equal to the fair market value of our common stock on the option
grant date. A director may pay the exercise

                                       61
<PAGE>   63

price by using cash, shares of common stock that the director already owns, or
an immediate sale of the option shares through a broker designated by us. The
non-employee directors' options have a 10-year term, except that they expire one
year after a director leaves the board (if earlier). If a change in control of
Quintus occurs, a non-employee director's option granted under the 1999 Director
Option Plan will become fully vested. Vesting also accelerates in the event of
the optionee's death or disability.

     Amendments or Termination. Our board may amend or terminate the 1999
Director Option Plan at any time. If our board amends the plan, it does not need
to ask for stockholder approval of the amendment unless applicable law requires
it. The 1999 Director Option Plan will continue in effect indefinitely, unless
the board decides to terminate the plan.

LOANS TO CERTAIN EXECUTIVE OFFICERS AND DIRECTORS


     On May 14, 1996, we loaned Alan Anderson, our Chief Executive Officer, a
total of $37,500 for the exercise of stock options. Mr. Anderson purchased

became the holder of a full-recourse promissory note from Mr. Anderson dated May
14, 1996 in the amount of $37,500 and bearing an interest rate of 6.36%,

     On April 20, 1999, we loaned Susan Salvesen, our Chief Financial Officer, a

became the holder of a full-recourse promissory note from Ms. Salvesen dated
April 20, 1999, in the amount of $164,868 and bearing an interest rate of 5.28%,

     In August 1996, Acuity loaned Mr. Busey $75,000. The note bore interest at
5.76% per annum and was collateralized by a stock pledge agreement secured by
shares owned by Mr. Busey. In 1998, Acuity forgave the note in connection with a
noncompete agreement Mr. Busey entered into with Acuity. Acuity received
interest payments of $4,320 and $2,160 during fiscal 1997 and 1998.

     We believe that the transactions above were made on terms no less favorable
to us than could have been obtained from unaffiliated parties. All future
transactions, including loans between us and our officers, directors, principal
stockholders and their affiliates, will be approved by a majority of the board
of directors, including a majority of the independent and disinterested
directors, and will continue to be made on terms no less favorable to us than
could have been obtained from unaffiliated parties.

ACUITY'S SALE OF ITS ICHAT BUSINESS

     In March 1999, Acuity sold its iChat business to KOZ, Inc. Under the terms
of an agency agreement between Mr. Busey and Acuity, Mr. Busey had the right to
receive 10% of the stock and cash received by Acuity for the sale of the iChat
assets. In June 1999, Acuity received 659,341 shares of KOZ Series E preferred
stock, valued at approximately $0.91 per share. Ten percent of these shares are
to be transferred to Mr. Busey, in accordance with the agency agreement. In
August 1999, Acuity received a payment of $310,000 from KOZ in connection with
the sale of the iChat business, creating an obligation to pay Mr. Busey $31,000.

                             PRINCIPAL STOCKHOLDERS

     The following table sets forth the beneficial ownership of our common stock
as of September 30, 1999 and as adjusted to reflect the closing of our
acquisition of Acuity and the sale of the common stock offered in this offering
for:

     - each person who is known by us to beneficially own more than 5% of our
       common stock;

     - each of the Named Executive Officers;

     - each of our directors; and

     - all of our directors and executive officers as a group (10 persons).

outstanding assuming the exercise of warrants to purchase 328,649 shares of
stock that were outstanding on that date. We will issue 4,551,441 shares in
connection with our acquisition of Acuity. Thus, the figures in the "Before
Offering" and "After Offering" columns below are based on 27,124,685 and
31,124,685 shares outstanding. The information in the table below assumes no
exercise of the underwriters' over-allotment option.

Securities and Exchange Commission and generally includes voting or investment
power with respect to securities. Shares of common stock subject to options
currently exercisable within 60 days of September 30, 1999 are deemed
outstanding for purposes of computing the percentage ownership of the person
holding such option but are not deemed outstanding for purposes of computing the
percentage ownership of any other person. Except where indicated, and subject to
community property laws where applicable, the persons in the table below have
sole voting and investment power with respect to all common stock shown as
beneficially owned by them. Unless otherwise indicated, the address of each of
the individuals listed in the table is c/o Quintus Corporation, 47212 Mission
Falls Court, Fremont, CA 94539.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

     At the closing of this offering, our authorized capital stock will consist
of 100,000,000 shares of common stock, $0.001 par value, and 10,000,000 shares
of preferred stock, $0.001 par value. The following summary of certain
provisions of the common stock and the preferred stock is not complete and is
qualified by our certificate of incorporation and bylaws and by the provisions
of applicable law.

COMMON STOCK

     As of September 30, 1999, there were 22,573,244 shares of common stock
outstanding that were held of record by approximately 193 stockholders. There
will be 31,124,685 shares of common stock outstanding, assuming the exercise of
328,649 warrants prior to the closing of this offering and no exercise of the
underwriters' over-allotment option and no exercise after September 30, 1999, of
outstanding options, and after giving effect to the issuance of 4,551,441 shares
in connection with our acquisition of Acuity, the sale of 4,000,000 shares of
common stock to the public in this offering and the conversion of our preferred
stock into common stock at a one-to-one ratio.

     The holders of our common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding preferred stock, the holders of common stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time by the board of directors out of funds legally available therefor. We
have never declared or paid cash dividends on our common stock or other
securities and do not currently anticipate paying cash dividends in the future.
Our bank line of credit currently prohibits the payment of dividends. In the
event of the liquidation, dissolution or winding up of Quintus, the holders of
common stock are entitled to share ratably in all assets remaining after payment
of liabilities, subject to prior distribution rights of preferred stock, if any,
then outstanding. The common stock has no preemptive or conversion rights or
other subscription rights. There are no redemption or sinking fund provisions
applicable to the common stock. All outstanding shares of common stock are fully
paid and nonassessable, and the shares of common stock to be issued upon the
effectiveness of this offering will be fully paid and nonassessable.

PREFERRED STOCK

     Our certificate of incorporation authorizes 10,000,000 shares of preferred
stock. The board of directors has the authority to issue the preferred stock in
one or more series and to fix the rights, preferences, privileges and
restrictions thereof, including dividend rights, dividend rates, conversion
rights, voting rights, terms of redemption, redemption prices, liquidation
preferences and the number of shares constituting any series or the designation
of such series, without further vote or action by the stockholders. The issuance
of preferred stock may have the effect of delaying, deferring or preventing a
change in control of Quintus without further action by the stockholders and may
adversely affect the voting and other rights of the holders of common stock. The
issuance of preferred stock with voting and conversion rights may adversely
affect the voting power of the holders of common stock, including the loss of
voting control to others. At present, we have no plans to issue any of the
preferred stock.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BYLAWS
AND DELAWARE LAW

     CERTIFICATE OF INCORPORATION AND BYLAWS


     The certificate of incorporation provides that, effective upon the closing
of this offering, all stockholder actions must be effected at a duly called
meeting and not by a consent in writing. The bylaws provide that our
stockholders may call a special meeting of stockholders only upon a request of
stockholders owning at least 10% of our capital stock. These provisions of the
certificate of incorporation and bylaws could discourage potential acquisition
proposals and could delay or prevent a change in control of Quintus. These
provisions are intended to enhance the likelihood of continuity and stability in
the composition of the board of directors and in the policies formulated by the
board of directors and to discourage certain types of transactions that may
involve an actual or threatened change of control of Quintus. These provisions
are designed to reduce the vulnerability of Quintus to an unsolicited
acquisition proposal. The provisions also are intended to discourage certain
tactics that may be used in proxy fights. However, such provisions could have
the effect of discouraging others from making tender offers for our shares and,
as a consequence, they also may inhibit fluctuations in the market price of our
shares that could result from actual or rumored takeover attempts. Such
provisions also may have the effect of preventing changes in our management. See
"Risk Factors--Anti-takeover provisions in our charter documents and Delaware
law, as well as provisions of employment agreements of some of our key
executives, could prevent or delay a change in control of Quintus."

     DELAWARE TAKEOVER STATUTE

     We are subject to Section 203 of the Delaware General Corporation Law,
which, with some exceptions, prohibits a Delaware corporation from engaging in
any business combination with any interested stockholder for a period of three
years following the date that such stockholder became an interested stockholder,
unless:

     - prior to such date, the board of directors of the corporation approved
       either the business combination or the transaction that resulted in the
       stockholder becoming an interested stockholder;

     - upon consummation of the transaction that 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 (a) by persons who are
       directors and also officers and (b) by employee stock plans in which
       employee participants do not have the right to determine confidentially
       whether shares held subject to the plan will be tendered in a tender or
       exchange offer; or

     - 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 that is not owned by the
       interested stockholder.

     Section 203 defines business combination to include:

     - any merger or consolidation involving the corporation and the interested
       stockholder;

     - any sale, transfer, pledge or other disposition of 10% or more of the
       assets of the corporation involving the interested stockholder;

     - with some exceptions, any transaction that results in the issuance or
       transfer by the corporation of any stock of the corporation to the
       interested stockholder;

     - any transaction involving the corporation that has the effect of
       increasing the proportionate share of the stock of any class or series of
       the corporation beneficially owned by the interested stockholder; or

     - the receipt by the interested stockholder of the benefit of any loans,
       advances, guarantees, pledges or other financial benefits provided by or
       through the corporation.

     In general, Section 203 defines an interested stockholder as any entity or
person beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by such entity or person.

REGISTRATION RIGHTS

     After this offering, the holders of 21,616,461 shares of common stock and
warrants to purchase common stock will be entitled to registration rights. If we
propose to register any of our securities under the Securities Act, either for
our own account or for the account of other security holders exercising
registration rights, we must notify these securityholders and these
securityholders may be entitled to include all or part of their shares in the
registration. Additionally, holders of 21,616,461 shares of common stock and
warrants to purchase common stock have demand registration rights under which
they may require us to use our best efforts to register shares of their common
stock. Further, the holders of these demand rights may require us to file
additional

                                       71
<PAGE>   73

registration statements on Form S-3. All of these registration rights are
subject to certain conditions and limitations, including the right of
underwriters to limit the number of shares included in a registration and our
right to not effect a requested registration within six months following an
offering of our securities, including this offering.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is ChaseMellon
Shareholder Services, L.L.C.

                        SHARES ELIGIBLE FOR FUTURE SALE

     Future sales of substantial amounts of common stock in the public market
following this offering, including shares issued upon exercise of outstanding
options and warrants, could adversely affect the prevailing market price of our
common stock and could impair our ability to raise capital through the sale of
our equity securities. As described below, most of the shares currently
outstanding will not be available for sale immediately after this offering due
to contractual and legal restrictions on resale. However, public sales of
substantial amounts of our common stock after these restrictions lapse could
adversely affect the prevailing market price of our stock and our ability to
raise equity capital in the future.


     Upon completion of this offering, we will have outstanding 31,124,685
shares of common stock, based upon shares outstanding as of September 30, 1999
and assuming no exercise of the underwriters' over-allotment option and no
exercise of outstanding options or warrants, other than 328,649 warrants prior
to the consummation of this offering. Of these shares, the 4,000,000 shares sold
in this offering will be freely tradable without restriction under the
Securities Act except for any shares purchased by our "affiliates," as that term
is defined in Rule 144 under the Securities Act. The remaining 27,124,685 shares
of common stock held by existing stockholders include 21,502,019 restricted
shares and 5,622,666 non-restricted shares. As described below, substantially
all of these 27,124,685 restricted and non-restricted shares are subject to
lock-up agreements or bylaw restrictions providing that, with certain limited
exceptions, the stockholder will not offer, sell, contract to sell or otherwise
dispose of any common stock or any securities that are convertible into common
stock for a period of 180 days after the date of this prospectus without the
prior written consent of Donaldson, Lufkin & Jenrette Securities Corporation. As
a result of these lock-up agreements and bylaw restrictions, only 27,752 of
these shares may be resold prior to 181 days after the date of this prospectus.
Donaldson, Lufkin & Jenrette Securities Corporation may, in its sole discretion
and at any time without notice, release all or any portion of the securities
subject to lock-up agreements or bylaw restrictions, although it has no current
intention of doing so.


     The following table shows approximately when the 27,124,685 shares of our
common stock that are not being sold in this offering, but which will be
outstanding when this offering is complete, will be eligible for sale in the
public market:

     Resale of 16,153,605 of the restricted shares that will become available
for sale in the public market starting 180 days after the date of this
prospectus will be limited by volume and other resale restrictions under Rule
144 because the holders of those shares are our affiliates.


RULE 144

     In general, under Rule 144, beginning 90 days after the date of this
prospectus, a person who has beneficially owned restricted shares for at least
one year would be entitled to sell within any three-month period a number of
shares that does not exceed the greater of:

     - 1% of the number of shares of common stock then outstanding, which will
       equal approximately 311,250 shares immediately after this offering; or

     - 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 and notice
requirements and to the public availability of information about us. Under Rule
144(k), a person who is not deemed to have been an affiliate of Quintus at any
time during the three months preceding a sale, and who has beneficially owned
the shares proposed to be sold for at least two years, is entitled to sell such
shares without complying with the manner of sale, public information, volume
limitation or notice provisions of Rule 144.

RULE 701


     Rule 701, as currently in effect, permits resales of shares in reliance
upon Rule 144 but without compliance with certain restrictions, including the
holding period requirement, of Rule 144. Any of our employees, officers,
directors or consultants who purchased shares under 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 nonaffiliates may sell such shares in reliance on Rule 144 without
having to comply with the holding period, public information, volume limitation
or notice provisions of Rule 144. All holders of Rule 701 shares are required to
wait until 90 days after the date of this prospectus before selling such shares.
However, all Rule 701 shares are subject to lock-up agreements or bylaw
restrictions and will only become eligible for sale upon the expiration of the
180 days following the date of this prospectus. Donaldson, Lufkin & Jenrette
Securities Corporation may, in its sole discretion and at any time without
notice, release all or any portion of the securities subject to lock-up
agreements or bylaw restrictions, although it has no current intent of doing so.



     Following the date of this prospectus, we will file a registration
statement on Form S-8 to register all the shares of common stock subject to
outstanding options or reserved for future issuance under our stock plans.
Common stock issued upon exercise of outstanding vested options or issued under
or purchase plan, other than common stock issued to our affiliates, will be
available for immediate resale in the open market.

</TABLE>


     The underwriting agreement provides that the obligations of the
underwriters to purchase and accept delivery of the shares of common stock
offered by this prospectus are subject to approval by their counsel of legal
matters concerning the offering and to conditions that must be satisfied by
Quintus. The underwriters are obligated to purchase and accept delivery of all
of the shares of common stock offered by this prospectus, other than those
shares covered by the over-allotment option described below, if any are
purchased.


     The underwriters initially propose to offer the shares of common stock in
part directly to the public at the initial public offering price set forth on
the cover page of this prospectus and in part to dealers, including the
underwriters, at such price less a concession not in excess of $     per share.
The underwriters may allow, and such dealers may re-allow, to other dealers a
concession not in excess of $     per share. After the initial offering of the
common stock, the public offering price and other selling terms may be changed
by the representatives at any time without notice. The underwriters do not
intend to confirm sales to any accounts over which they exercise discretionary
authority.

     An electronic prospectus will be available on the Web site maintained by
DLJdirect Inc., an affiliate of Donaldson, Lufkin & Jenrette Securities
Corporation. Other than the prospectus in electronic format, the information on
this Web site relating to the offering is not part of this prospectus and has
not been approved or endorsed by Quintus or the underwriters, and should not be
relied on by prospective investors.


     Quintus has granted to the underwriters an option, exercisable for 30 days
after the date of this prospectus, to purchase, from time to time, in whole or
in part, up to an aggregate of 600,000 additional shares of common stock at the
initial public offering price less underwriting discounts and commissions. The
underwriters may exercise the option solely to cover over-allotments, if any,
made in connection with the offering. To the extent that the underwriters
exercise the option, each underwriter will become obligated, subject to
conditions contained in the underwriting agreement, to purchase its pro rata
portion of such additional shares based on the underwriters' percentage
underwriting commitment as indicated in the above table.


                                       74
<PAGE>   76

     Quintus has agreed to indemnify the underwriters against liabilities which
may arise in connection with the offering, including liabilities under the
Securities Act of 1933, or to contribute to payments that the underwriters may
be required to make.


     Quintus, its executive officers and directors and substantially all of its
stockholders and option holders are subject to agreements or bylaw restrictions
providing that, with certain limited exceptions, they will not:


     - offer, pledge sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant to purchase, lend, or otherwise transfer or dispose of
       directly or indirectly any shares of common stock or any securities
       convertible into or exercisable or exchangeable for common stock; or

     - enter into any swap or other arrangement that transfers to another, in
       whole or in part, any of the economic consequences of ownership of the
       common stock, whether any such transaction described above is to be
       settled by delivery of common stock or other securities, in cash or
       otherwise


for a period of 180 days after the date of this prospectus. Donaldson, Lufkin &
Jenrette Securities Corporation may release some or all of these shares from
such restrictions prior to the expiration of the 180-day period lock-up period,
although it has no current intention of doing so.



     In addition, during such 180-day period, Quintus has also agreed not to
file any registration statement with respect to the registration of any shares
of common stock or any securities convertible into or exercisable or
exchangeable for common stock without the prior written consent of Donaldson,
Lufkin & Jenrette Securities Corporation. Furthermore, no Quintus stockholders
have demand registration rights that may be exercised during such 180 day
period.



     Prior to the offering, there has been no established trading market for the
common stock. The initial public offering price of the shares of common stock
offered by this prospectus will be determined by negotiation among Quintus and
the underwriters. The factors to be considered in determining the initial public
offering price include:


     - the history of and the prospects for the industry in which Quintus
       competes;

     - the past and present operations of Quintus;

     - the historical results of operations of Quintus;

     - the prospectus for future earnings of Quintus;

     - the recent market prices of securities of generally comparable companies;
       and

     - the general condition of the securities markets at the time of the
       offering.


     The underwriters have reserved up to 200,000 shares of the common stock to
be sold in this offering for sale to some of our employees and associates of our
employees and directors, and to other individuals or companies who have
commercial arrangements or personal relationships with us. Through this directed
share program, we intend to ensure that those individuals and companies that
have supported us, or who are in a position to support us in the future, have
the opportunity to purchase our common stock at the same price that we are
offering our shares to the general public. Prospective participants will not
receive any investment materials other than a copy of this prospectus, and will
be permitted to participate in this offering at the initial public offering
price presented on the cover page of this prospectus. No commitment to purchase
shares by any participant in the directed share program will be accepted until
after the registration statement of which this


                                       75
<PAGE>   77


prospectus is a part is effective and an initial public offering price has been
established. The number of shares available for sale to the general public will
be reduced by the number of shares sold through the directed share program. Any
shares reserved for the directed share program which are not so purchased will
be offered by the underwriters to the general public on the same basis as the
other shares offered hereby.


     Other than in the United States, no action has been taken by Quintus or the
underwriters that would permit a public offering of the shares of common stock
offered in any jurisdiction where action for that purpose is required. The
shares of common stock offered may not be offered or sold, directly or
indirectly, nor may this prospectus or any other offering material or
advertisements in connection with the offer and sale of any such shares of
common stock be distributed or published in any jurisdiction, except under
circumstances that will result in compliance with the applicable rules and
regulations of such jurisdiction. Persons into whose possession this prospectus
comes are advised to inform themselves about and observe any restrictions
relating to the offering and the distribution of this prospectus. This
prospectus does not constitute an offer to sell or a solicitation of an offer to
buy any shares of common stock offered in any jurisdiction in which such an
offer or a solicitation is unlawful.

     DLJ Capital Corporation, Sprout Capital VI, L.P., Sprout Capital VII, L.P.,
Sprout CEO Fund, L.P. and DLJ ESC II, L.P., collectively referred to as the
"Sprout Entities," are affiliates of Donaldson, Lufkin & Jenrette Securities
Corporation, one of the underwriters. As described under "Principal
Stockholders," the Sprout Entities beneficially own an aggregate of 11,842,037
shares of the outstanding common stock, which represent more than 10% of the
outstanding common stock. The Sprout Entities have placed a sufficient number of
their shares in a voting trust so that upon the closing of this offering, the
Sprout Entities will exercise voting control over less than five percent of the
outstanding common stock. The shares subject to the voting trust are held and
voted by an independent third party, Norwest Bank Indiana, N.A., as voting
trustee.


     Because the Sprout Entities affiliated with Donaldson, Lufkin & Jenrette
Securities Corporation beneficially own more than 10% of the outstanding common
stock, this offering is being conducted in accordance with Rule 2720 of the
Conduct Rules of the National Association of Securities Dealers, Inc., which
provides that the public offering price of an equity security be no higher than
that recommended by a "qualified independent underwriter" meeting certain
standards. In accordance with this requirement, Dain Rauscher Wessels, a
division of Dain Rauscher Incorporated, will assume the responsibilities of
acting as qualified independent underwriter and will recommend a price in
compliance with the requirements of Rule 2720. As compensation for its services
as qualified independent underwriter, we have agreed to pay $10,000 to Dain
Rauscher Wessels on the closing of this offering.


     In connection with the offering, the underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
common stock. Specifically, the underwriters may over-allot the offering,
creating a syndicate short position. The underwriters may bid for and stabilize
the price of the common stock. In addition, the underwriting syndicate may
reclaim selling concessions from syndicate members and selected dealers if they
repurchase previously distributed common stock in syndicate covering
transactions, in stabilizing transactions or otherwise. These activities may
stabilize or maintain the market price of the common stock above independent
market levels. The underwriters are not required to engage in these activities,
and may end any of these activities at any time.

                                 LEGAL MATTERS

     The validity of the common stock offered in this offering will be passed
upon for us by Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP,

will be passed upon for the underwriters by Wilson Sonsini Goodrich & Rosati,

                                    EXPERTS

     The Quintus consolidated financial statements as of and for the year ended
March 31, 1999, included in this prospectus and the related financial statement
schedule for the year ended March 31, 1999 included elsewhere in the
registration statement have been audited by Deloitte & Touche LLP, independent
auditors, as stated in their reports appearing herein and elsewhere in the
registration statement, and have been so included in the reliance upon the
reports of such firm given upon their authority as experts in auditing and
accounting.

     Ernst & Young LLP, independent auditors, have audited our consolidated
financial statements and schedules at March 31, 1998, and for the two years in
the period then ended, as set forth in their report. We've included our
financial statements and schedule in the prospectus and elsewhere in the
registration statement in reliance on Ernst & Young LLP's report, given on their
authority as experts in accounting and auditing.

     The Acuity financial statements as of December 31, 1997 and 1998 and for
each of the two years in the period ended December 31, 1998 included in this
prospectus and registration statement have been so included in reliance on the
report of PricewaterhouseCoopers LLP, independent accountants, given on the
authority of that firm as experts in auditing and accounting.

                             CHANGE IN ACCOUNTANTS

     On March 9, 1999, our audit committee dismissed Ernst & Young LLP as our
independent auditors and subsequently appointed Deloitte & Touche LLP as our
principal accountants. There were no disagreements with the former accountants
during the fiscal years ended March 31, 1997 and 1998 or during any subsequent
interim period preceding their replacement on any matter of accounting
principles or practices, financial statement disclosure, or auditing scope or
procedures, which disagreements, if not resolved to the former accountants'
satisfaction, would have caused them to make reference to the subject matter of
the disagreement in connection with their reports. The former independent
auditors issued an unqualified report on the financial statements as of and for
the years ended March 31, 1997 and 1998. We did not consult with Deloitte &
Touche LLP on any accounting or financial reporting matters in the periods prior
to their appointment. The change in accountants was approved by our board of
directors.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of
Quintus Corporation:

     We have audited the accompanying consolidated balance sheet of Quintus
Corporation and subsidiaries (the Company) as of March 31, 1999, and the related
consolidated statements of operations, stockholders' deficiency, and cash flows
for the year then ended. 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 audit.

     We conducted our audit 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 audit provides a reasonable basis for our opinion.

     In our opinion, such consolidated financial statements referred to above
present fairly, in all material respects, the financial position of the Company
as of March 31, 1999, and the results of its operations and its cash flows for
the year then ended in conformity with generally accepted accounting principles.

                              QUINTUS CORPORATION

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
               YEARS ENDED MARCH 31, 1997, 1998 AND 1999 AND SIX
                  MONTHS ENDED SEPTEMBER 30, 1999 (UNAUDITED)

 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Quintus Corporation (Quintus or the Company) provides a comprehensive
e-Customer Relationship Management ("eCRM") solution to manage customer
interactions and deliver consistent customer service across multiple
communication channels, including the Internet, email and advanced telephony
systems. The Company was founded in Delaware in May 1995.

     Basis of Presentation -- The consolidated financial statements include the
accounts of the Company and its wholly-owned subsidiaries after the elimination
of all significant intercompany balances and transactions.

     Liquidity -- As disclosed in the consolidated financial statements during
the years ended March 31, 1997, 1998 and 1999, the Company incurred net losses
from continuing operations of $3,526,000, $10,146,000 and $10,586,000 and had
net cash outflows from continuing operations of $2,000,000, $3,950,000 and
$7,300,000. The Company had a stockholders' deficiency of $20,091,000 at March
31, 1999. Management expects to incur further losses in fiscal year 2000. In
addition, in September 1999 the Company entered into an agreement to acquire
Acuity Corporation (see Note 15). Acuity Corporation has a history of losses and
net cash outflows from operations. In August 1999, the Company secured
$11,247,500 in equity financing (see Note 15). Management believes that this
equity financing when combined with existing cash on hand will be sufficient to
meet the Company's minimum obligations through March 31, 2000. However, the
Company will seek additional financing in the near term to execute its business
strategies and meet its longer term obligations.

     Use of Estimates -- The preparation of 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 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.

     Property and Equipment -- Property and equipment are recorded at cost and
depreciated using the straight-line method over the estimated useful lives of
the assets, which are generally two to five years. Assets recorded under capital
leases are amortized by the straight-line method over the shorter of their
respective useful lives or the lease term.

     Revenue Recognition -- Statement of Position 97-2, Software Revenue
Recognition ("SOP 97-2"), was issued in October 1997 by the American Institute
of Certified Public Accountants ("AICPA") and was amended by Statement of
Position 98-4 ("SOP 98-4"). The Company adopted SOP 97-2 effective April 1, 1998
and SOP 98-4 effective March 31, 1998. The Company believes its current revenue
recognition policies and practices are consistent with SOP 97-2 and SOP 98-4.
Additionally, the AICPA issued SOP 98-9 in March 1998, which provides for
certain amendments to SOP 97-2, and is effective for transactions entered into
by the Company beginning April 1, 1999. The adoption of these amendments did not
have a material impact on its financial position, results of operations or cash
flows.

     The Company licenses software to end users under noncancelable license
agreements and provides services such as installation, implementation, training,
and software maintenance. Software

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
               YEARS ENDED MARCH 31, 1997, 1998 AND 1999 AND SIX
                  MONTHS ENDED SEPTEMBER 30, 1999 (UNAUDITED)

license revenue for contracts not requiring significant customization services
is recognized upon meeting each of the following criteria: an executed agreement
has been signed; products have been shipped; the license fee is fixed and
determinable; collection of the resulting receivable is probable; and vendor
specific objective evidence exists to allocate the total fee to elements of the
arrangement. Vendor-specific objective evidence is based on the price generally
charged when an element is sold separately, or if not yet sold separately, is
established by authorized management. For sales made through distributors the
Company generally recognizes revenue at the time these partners report to the
Company that they have sold the software to the end users and all revenue
recognition criteria have been met. Software license revenue from contracts
requiring the Company to perform significant customization services are
recognized on the percentage-of-completion method based on the ratio of labor
hours incurred to total estimated labor hours. Provisions for estimated losses
on contracts are made in the period in which the anticipated losses become
known. Actual costs and gross margins on such contracts could differ from
management's estimates, and such differences could be material to the financial
statements. Allowances for estimated future warranty costs are provided at the
time revenue is recognized. Service revenue includes maintenance revenue, which
is deferred and recognized ratably over the maintenance period, which in most
cases is one year, and revenue from training services which is recognized as
services are performed. Consulting revenues are recognized as services are
performed.

     Software Development Costs -- Costs for the development of new software
products and substantial enhancements to existing software products are expensed
as incurred until technological feasibility has been established, at which time
any additional costs would be capitalized in accordance with Statement of
Financial Accounting Standards (SFAS) No. 86, Computer Software to be Sold,
Leased or Otherwise Marketed. The costs to develop such software have not been
capitalized as the Company believes its current software development process is
essentially completed concurrent with the establishment of technological
feasibility.

     Impairment of Long-Lived Assets -- In accordance with Statement of
Financial Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," the Company
evaluates its long-lived assets for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable.

     Intangible Assets -- Intangible assets, including purchased technology, are
related to the business acquisitions described in Note 2. Amortization is
recorded on a straight-line basis over a period of three years.

     Income Taxes -- The Company accounts for income taxes under Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes. Under this
method, deferred tax liabilities and assets are recognized for the expected
future tax consequences of temporary differences between the carrying amounts
and the tax bases of assets and liabilities. A valuation allowance is recorded
to reduce net deferred tax assets to amounts that are more likely than not to be
realized.

     Stock-Based Compensation -- The Company accounts for employee stock options
in accordance with Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" (APB Opinion No. 25).

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
               YEARS ENDED MARCH 31, 1997, 1998 AND 1999 AND SIX
                  MONTHS ENDED SEPTEMBER 30, 1999 (UNAUDITED)

     Loss per Common Share -- Basic loss per common share excludes dilution and
is computed by dividing loss applicable to common stockholders by the weighted
average number of common shares outstanding, less the weighted average number of
common shares subject to repurchase by the Company. Diluted loss per common
share reflects the potential dilution that could occur if securities or other
contracts to issue common stock (convertible preferred stock, warrants and
common stock options) were exercised or converted into common stock. Common
share equivalents are excluded from the computation in loss periods as their
effect would be antidilutive.

     Pro Forma Net Loss per Share -- The Company intends to make a $17,811,000
cash distribution to convertible preferred stockholders payable upon conversion
to common stock (see Note 8) using a portion of the proceeds from its planned
initial public offering. Pro forma basic and diluted net loss per share amounts
are calculated using the weighted average number of common shares outstanding
for the period (excluding shares subject to repurchase), the weighted average
number of common shares resulting from the assumed conversion of all outstanding
shares of convertible preferred stock upon the closing of the initial public
offering contemplated by this Prospectus plus the number of shares whose
proceeds are to be used to repay the cash distribution, assuming a $13 offering
price, reduced by expected per share offering costs.

     Unaudited Interim Financial Information -- The interim financial
information for the six months ended September 30, 1998 and 1999 is unaudited
and has been prepared on the same basis as the audited financial statements. In
the opinion of management, such unaudited financial information includes all
adjustments (consisting only of normal recurring adjustments) necessary for a
fair presentation of the interim information.

     Foreign Currency Transactions -- The functional currency of the Company's
foreign subsidiaries is the U.S. dollar. Accordingly, all monetary assets and
liabilities are remeasured at the current exchange rate at the end of each
period reported. Nonmonetary assets and liabilities are remeasured at historical
rates and revenues and expenses are remeasured at average exchange rates in
effect during the period, except for those expenses related balance sheet
amounts that are remeasured at historical exchange rates. Transaction gains and
losses, which are included in other income (expense) in the accompanying
consolidated statements of operations, have not been significant.

     Concentration of Credit Risk -- Financial instruments which potentially
subject the Company to concentrations of credit risk consist primarily of trade
receivables. The Company sells its products to companies in diverse industries
and generally does not require its customers to provide collateral to support
accounts receivable. To reduce credit risk, management performs ongoing credit
evaluations of its customers' financial condition. The Company maintains
allowances for potential credit losses.

     Certain Significant Risks and Uncertainties -- The Company operates in the
software industry, and accordingly, can be affected by a variety of factors. For
example, management of the Company believes that changes in any of the following
areas could have a significant negative effect on the Company's future financial
position, results of operations and cash flows: ability to obtain additional
financing; regulatory changes; fundamental changes in the technology underlying
software products; market acceptance of the Company's products under
development; development of distribution channels; ability to implement and
expand operational customer support and financial control systems to manage
rapid growth, both domestically and internationally; the hiring and retention of
key

employees; relationship with Lucent; fundamental changes in technology
underlying software products; litigation or other claims against the Company.

     Recently Issued Accounting Standards -- In 1998, the Company adopted
Statement of Financial Accounting Standards (SFAS) No. 130, Reporting
Comprehensive Income, which requires an enterprise to report, by major
components and as a single total, the change in net assets during the period
from nonowner sources. The Company's comprehensive loss was equal to its net
loss for all years presented.

     In 1998, the Company adopted SFAS No. 131, Disclosures About Segments of an
Enterprise and Related Information, which established annual and interim
reporting standards for an enterprise's business segments and related
disclosures about its products, services and geographic areas and major
customers. The Company operates in two reportable segments (see Note 15).

     In March 1998, the Accounting Standards Executive Committee (AcSEC) issued
SOP 98-1, Accounting for the Costs of Computer Software Developed or Obtained
for Internal Use. SOP 98-1 establishes the accounting for costs of software
products developed or purchased for internal use, including when such costs
should be capitalized. SOP 98-1 will be effective for the Company's fiscal year
ending March 31, 2000. The Company believes the adoption of this statement will
not have a significant impact on its financial position, results of operations
or cash flows.

     In April 1998, the AcSEC issued SOP 98-5, Reporting on the Costs of
Start-up Activities. Under SOP 98-5, the cost of start-up activities should be
expensed as incurred. SOP 98-1 will be effective for the Company's fiscal year
ending March 31, 2000. The Company believes the adoption of this statement will
not have a significant impact on its financial position, results of operations
or cash flows.

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities. This statement
requires companies to record derivatives on the balance sheet as assets or
liabilities, measured at fair value. Gains or losses resulting from changes in
the values of those derivatives would be accounted for depending on the use of
the derivative and whether it qualifies for hedge accounting. SFAS No. 133 will
be effective for the Company's fiscal year ending March 31, 2001. Management
believes that this statement will not have a significant impact on the Company's
financial position, results of operations or cash flows.

 2. BUSINESS COMBINATIONS AND DISCONTINUED OPERATIONS

     CALL CENTER ENTERPRISES, INC.

     In July 1997, the Company acquired Call Center Enterprises, Inc. (CCE), a
provider of strategic call center consulting services, for $965,000 in cash in a
transaction that was accounted for as a purchase. Assets acquired and
liabilities assumed in the acquisition were as follows (in thousands):

                  MONTHS ENDED SEPTEMBER 30, 1999 (UNAUDITED)

     During fiscal 1999 the Company was required to make additional cash
payments of approximately $962,000 to former stockholders of CCE based upon
achievement of certain performance goals. These payments, which were contingent
upon the continued employment of the former CCE stockholders, were recorded as
charges to operations when the performance goal was attained.

     On February 26, 1999, the Company sold the assets of CCE, which provided
implementation services for support and help-desk centers software application.
The division was sold for cash of $2,100,0000 with a gain on disposal of
$1,011,000. As a result, the operations of CCE have been classified as
discontinued operations in the statement of operations. The Company recorded
$453,000 as a reduction in the gain on disposal of discontinued operations for
the fair value of options, due to the Company accelerating vesting of CCE
employees' options as if they had been employed for 12 additional months. The
Company may receive an additional payment of up to $400,000 from the sale of CCE
based on the number of former CCE employees who remain employed by the purchaser
for one year subsequent to the date of disposition. The division had revenues of
$2,528,000 and $3,210,000 for the years ended March 31, 1998 and 1999,
respectively. There were no assets or liabilities remaining as of March 31,
1999.

     NABNASSET CORPORATION

     In November 1997, the Company acquired Nabnasset Corporation (Nabnasset), a
provider of software which integrates telephone, voice, and data for $1,496,000
in cash, preferred stock with a fair value of $1,000,000, and 518,921 shares of
common stock and options to purchase 617,528 shares of common stock with an
aggregate fair value of $1,044,000. The transaction was accounted for as a
purchase. Assets acquired and liabilities assumed in the acquisition were as
follows (in thousands):

     In this acquisition, acquired technology included both existing technology
and in-process research and development. The valuation of acquired technology
was made by applying the income forecast method, which considers the present
value of cash flows by product lines. As of the date of acquisition, multiple
research and development projects were underway including efforts related to the
next generation of Voice Enhanced Services Platform (VESP). The key elements of
Nabnasset's development process include: sales specification, functional
specifications, prototype development, question and answer sessions,
documentation and product release. A project is considered to be technologically
feasible upon the completion of beta testing that occurs as the final step in
the prototype development phase. At the date of acquisition, an additional
research and development effort of approximately 14 months was anticipated prior
to its release. Value was allocated to in

process research and development based on a discounted cashflow model and
considered the core technology resident in the in-process products, Nabnasset's
past experience with typical product life cycles, demand from Nabnasset
customers for new versions incorporating additional features, the migration of
technology between platforms and the roadmap for future development. Quintus
completed development of the next generation of VESP and introduced CTI version
5.0 in January 1999. This version is sold on a stand-alone basis as a CTI
product and is also integrated into Quintus' eContact suite. Acquired in-process
technologies were charged to operations, as the technologies did not have
alternative future uses as of the date of the acquisition.

     The operating results of Nabnasset have been included in the consolidated
statements of operations since the date of acquisition. Had the acquisition
taken place at the beginning of fiscal 1997, the unaudited pro forma results of
operations would have been as follows for the year ended March 31, (in
thousands, except per share data):

     The pro forma results of operations give effect to certain adjustments,
including amortization of purchased intangibles and goodwill. The $2,200,000
charge for purchased in-process technology has been excluded from the pro forma
results as it is a material non-recurring charge.

converted. The remainder was credited to redeemable preferred stock which is
presented outside of stockholders' equity. For each of the years ended March 31,
1997 and 1998, accretion of preferred stock totaled $167,000 and $1,519,000,
respectively, to reflect the difference between the carrying value and the
redemption value of the preferred stock on the date of issuance. The accretion
of the preferred stock has been recorded as an increase to the carrying value of
the redeemable preferred stock and a reduction of additional paid in capital.
There was no accretion for the year ended March 31, 1999.

     The holder of each share of Series A convertible preferred stock has the
right to 10 votes, and the holder of each share of Series B, C, and D
convertible preferred stock has the right to 14 votes for each share of common
stock into which Series A, B, C, and D convertible preferred stock can be
converted.

     The holders of Series A, B, C, and D convertible preferred stock are
entitled to noncumulative annual dividends of $0.20, $0.286, $0.382 and $0.55
per share, respectively, as declared by the Board of Directors, prior to the
payment of dividends to the holders of common stock. No cash dividends have been
declared through March 31, 1999.

     In the event of any voluntary or involuntary liquidation of the Company,
the Series A, B, C and D convertible preferred stockholders are entitled to a
liquidation preference of $1,00, $1.43, $1.91 and $2.75 per share, respectively,
plus accrued dividends, if any.

     ADDITIONAL STOCK PLAN INFORMATION

     Statement of Financial Accounting Standards No. 123, Accounting for
Stock-Based Compensation, (SFAS No. 123) requires the disclosure of pro forma
net income and earnings per share had the Company adopted the fair value method
as of the beginning of fiscal 1995. Under SFAS No. 123, the fair value of the
stock-based awards to employees is calculated through the use of option pricing
models, even though such models were developed to estimate the fair value of
freely tradable, fully transferable options without vesting restrictions, which
significantly differ from the Company's stock option awards. These models also
require subjective assumptions, including future stock price volatility and
expected time to exercise, which greatly affect the calculated values. The
Company's calculations were made using the minimum value method with the
following weighted average assumptions for 1997, 1998 and 1999; expected life,
5.2 years for 1997 grants, 6.0 years for 1998 grants, and 6.0 years for 1999
grants; risk free interest rates of 6.4% in 1997 and 6.0% in both 1998 and 1999;
and no dividends during the expected term. The Company's calculations are based
on a multiple option valuation approach and forfeitures are recognized as they
occur. If the computed fair values of the stock-based awards had been amortized
over the vesting period of the awards, pro forma net loss applicable to common
stockholders would have been approximately $3,713,000 ($4.28 per basic and
diluted share), $13,185,000 ($7.78 per basic and diluted share), and $11,887,000
($4.19 per basic and diluted share) for the years ended March 31, 1997, 1998 and
1999, respectively. However, the impact of outstanding nonvested stock options
granted prior to 1995 has been excluded from the pro forma calculation;
accordingly, the pro forma adjustments are not indicative of future period pro
forma adjustments, when the calculation will apply to all applicable stock
options.

     STOCK-BASED COMPENSATION

     In connection with options granted to employees to purchase common stock,
the Company recorded deferred stock compensation of $99,000 and $1,055,000 in
fiscal years 1998 and 1999, respectively. The Company had no deferred stock
compensation in fiscal year 1997. Such amounts represent the difference between
the exercise price and the deemed fair value of the Company's common stock at
the date of grant. The deferred charges are being amortized to expense through
fiscal year 2003. Stock-based compensation expense of $20,000 was recognized as
part of the Company's discontinued operations during fiscal year 1998. There was
no stock-based compensation

     Deferred income taxes reflect the tax effects of temporary differences
between the carrying amount of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes, as well as net operating
loss and tax credit carryforwards. Due to the uncertainty surrounding the
realization of the benefits of its favorable tax attributes in future tax
returns, as of March 31, 1998 and 1999, the Company has fully reserved its net
deferred tax assets of approximately $6,320,000 and $9,142,000, respectively.

     For all periods presented the Company's effective rate differs from the
expected benefit at the federal statutory tax rate due primarily to state taxes
of approximately 5% offset by a valuation allowance against deferred tax assets.

     The Company's loss from continuing operations for 1999 was generated by
$9,081,000 and $1,505,000 from domestic and international operations,
respectively. The Company did not have international operations in 1997 and
1998.

                  MONTHS ENDED SEPTEMBER 30, 1999 (UNAUDITED)

     At March 31, 1999, the Company has net operating loss (NOL) carryforwards
of approximately $24,215,000 and $5,386,000 for federal and state income tax
purposes, respectively. The federal NOL carryforwards expire beginning in 2011,
while the state NOL carryforwards expire beginning in 2001.

     At March 31, 1999, the Company also has research and development credit
carryforwards of approximately $242,000 and $128,000 available to offset future
federal and state income taxes, respectively. The federal credit carryforward
expires beginning in 2011, while the state credit carryforward has no
expiration.

     The extent to which the loss and credit carryforwards can be used to offset
future taxable income and tax liabilities, respectively, may be limited,
depending on the extent of ownership changes within any three-year period.

12. SAVINGS PLAN

     The Company maintains a savings plan under Section 401(k) of the Internal
Revenue Code. Under the plan, employees may defer a portion of their pretax
salaries. The Company makes no matching contributions.

13. SEGMENT INFORMATION, OPERATIONS BY GEOGRAPHIC AREA AND SIGNIFICANT CUSTOMERS

     SIGNIFICANT CUSTOMERS

     One unrelated customer accounted for 23.8% and 19.3% of total revenues in
1997 and 1999, respectively. No one customer accounted for greater than 10% of
total revenues in fiscal 1998.

     Four customers accounted for 30.9%, 21.8%, 10.9% and 10.5% of accounts
receivable at March 31, 1997. One customer accounted for 21.1% and 28.6% of
accounts receivable at March 31, 1998 and 1999, respectively.

14. LITIGATION

     The Company is a defendant and may be a potential defendant in lawsuits and
claims arising in the ordinary course of business. While the outcomes of such
claims, lawsuits, or other proceedings cannot be predicted with certainty,
management expects that such liability, to the extent not provided by insurance
or otherwise, will not have a material adverse effect on the financial condition
of the Company.

15. SUBSEQUENT EVENTS


     On July 19, 1999, as part of a license grant, the Company issued a customer
a warrant to purchase up to 300,000 shares of the Company's common stock at an
exercise prices per share equal to the lesser of (i) the initial public offering
price, net of commissions, per one share of the Company's common stock or (ii)
$7.50 per share. All revenues, not subject to a contingency, have been recorded
during the quarter ended September 30, 1999 and the resolution of the
contingency has no bearing on the customer earning the warrant, which was earned
on July 19, 1999. Therefore, the fair value of the warrant of approximately
$560,000, was recorded as a discount to reduce revenue in the quarter ended
September 30, 1999. The Company's calculations were made using the Black Scholes
model with the following assumptions: expected life of 1.2 years; risk-free
interest rate of 6.0%; volatility of 50%; and no dividends during the expected
term.


     On August 26, 1999, the Company issued a total of 1,363,334 shares of
Series F convertible preferred stock at $8.25 per share for cash consideration
of $11,247,500. The Series F convertible preferred stock is convertible into one
share of common stock and has preferences, liquidation and voting rights similar
to those of Series E preferred stock. The Series F preferred stockholders are
entitled to no cash payments upon conversion to common stock.

     On September 10, 1999, Quintus entered into an Agreement and Plan of
Reorganization to acquire all of the outstanding shares and assume the
outstanding options and warrants of Acuity Corp. (Acuity), a company
specializing in providing Web based customer interaction software. Quintus will
issue approximately 1,546,586 shares of common stock valued at approximately
$12,760,000, approximately 3,004,855 shares of Series G preferred stock valued
at approximately $24,790,000, and assume approximately 1,201,882 options and
warrants to purchase common and preferred stock valued at approximately
$7,670,000. The aggregate purchase price, including approximately $300,000 of
transaction costs not paid in stock, will be approximately $45,520,000. The
agreement is subject to shareholder approval and is expected to close in
November 1999. The acquisition will be accounted for using the purchase method
of accounting.

                  MONTHS ENDED SEPTEMBER 30, 1999 (UNAUDITED)

     On September 9, 1999, the Board of Directors approved, subject to
stockholder approval, the following:

     ADOPTION OF THE 1999 STOCK INCENTIVE PLAN

     1,000,000 shares of common stock were reserved for issuance under the 1999
Stock Incentive Plan. Any shares not yet issued under the 1995 Stock Option Plan
on the date of this offering will also be available under the 1999 Stock
Incentive Plan. On January 1 of each year, starting with the year 2000, the
number of shares in the reserve will automatically increase by 5% of the total
number of shares of common stock that are outstanding at that time or, if less,
by 2,000,000 shares. In general, if options or shares awarded under the 1999
Stock Incentive Plan or the 1995 Stock Incentive Plan are forfeited, then those
options or shares will again become available for awards under the 1999 Stock
Incentive Plan.

     Outstanding options under the 1995 Stock Option Plan will be incorporated
into the 1999 Equity Incentive Plan at the time of this offering and no further
option grants will be made under the 1995 Stock Option Plan. The incorporated
options will continue to be governed by their existing terms, unless the Board
elects one or more features of the 1999 Stock Incentive Plan to those options or
to other outstanding shares. The Board has elected to extend the change in
control acceleration feature of the 1999 Stock Inventive Plan to all outstanding
options and unvested shares. Previously, options granted under the 1995 Stock
Option Plan provided that vesting of the shares would accelerate upon an
acquisition only if not assumed by the acquiring entity.

     ADOPTION OF THE EMPLOYEE STOCK PURCHASE PLAN

     Under the purchase plan, eligible employees are allowed to have salary
withholdings of up to 15% of their cash compensation to purchase shares of
common stock at a price equal to 85% of the lower of the market value of the
stock on the first date immediately before the first day of the applicable
offering period or the fair market value on the purchase date. The initial
offering period commences upon the effective date for the initial public
offering of the Company's common stock. For the first offering period, shares of
common stock may be purchased at a price equal to 85% of the lower of the price
per share in the initial public offering or the market value on the purchase
date. The Company has initially reserved 1,000,000 shares of common stock under
this plan, plus an annual increase to be added on May 1st beginning with the
year 2000 equal to the lesser of (i) 1,000,000 shares, or (ii) 2% of the shares
of common stock outstanding on May 1st.

     ADOPTION OF THE DIRECTORS OPTION PLAN

     500,000 shares of common stock have been reserved under the Director Option
Plan. The plan provides for an initial automatic grant of an option to purchase
30,000 shares of common stock to a nonemployee director who first becomes a
director after the Company's initial public offering. The grant will occur when
the director takes office. The initial option will vest monthly over the
two-year period following the date of grant. In addition, at the time of the
annual stockholders' meeting beginning in 2000, each nonemployee director who
continues to be a director after that meeting will automatically be granted an
annual option to purchase 10,000 shares of common stock. However, a nonemployee
director who is receiving the 30,000 option initial grant will not receive the
annual

option in the same calendar year. The annual options are fully vested on the
first anniversary of the date of grant.

     Effective September 29, 1999, the Company amended the loan and security
agreement and limited waiver, maintained with a bank, to extend the maturity
date of the Company's revolving line for borrowings up to $7,500,000 from
September 17, 1999 to December 17, 1999. Changes to the terms of the line
included a waiver to the financial covenants as well as a change of the interest
rate to prime plus 0.5% per annum. In addition, the Company granted the bank a
warrant to purchase 25,000 shares of Series F Preferred Stock at an exercise
price of $8.25 per share. The fair value of the warrant was deemed at $100,000,
which will be amortized over the extension of the maturity date. The Company's
calculations were made using the Black Scholes model with the following
assumptions: expected life of .2 years; risk-free interest rate of 6.0%;
volatility of 50%; and no dividends during the expected term.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of Acuity Corp.

     In our opinion, the accompanying balance sheets and the related statements
of operations, changes in stockholders' equity and cash flows present fairly, in
all material respects, the financial position of Acuity Corp. (the "Company"),
at December 31, 1997 and 1998, and the results of its operations and its cash
flows for the years then ended, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these statements in
accordance with generally accepted auditing standards which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company has sustained recurring losses from operations
in the years then ended December 31, 1997 and 1998 which raise substantial doubt
about its ability to continue as a going concern. Management's plans in regard
to these matters are also discussed in Note 1. The financial statements do not
include any adjustments that might result from the outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS

 1. BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

     Acuity Corp., a Delaware corporation (the "Company") was incorporated on
August 2, 1995 as ichat, Inc. The Company is a provider of Web-based customer
interaction software. In June 1998 the Company changed its name to Acuity Corp.
to reflect a strategic change in its core product offerings from internet chat
software to its WebCenter customer interaction software. Shortly thereafter, the
Company commenced shipment of its WebCenter products that enable users to
interact with their customers over the Internet. During the year ended December
31, 1998, WebCenter revenue was approximately $1,215,000 and ichat revenue was
$5,504,000.

BASIS OF PRESENTATION

     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. The Company has incurred operating
losses since inception related primarily to the development and marketing of its
products and has an accumulated deficit of $19,467,520 as of December 31, 1998.
These factors raise substantial doubt about the Company's ability to continue as
a going concern. In February 1999, the Company completed a sale of preferred
stock and in March 1999 completed the sale of an exclusive license to its chat
technology (see note 11). The Company's management has developed a fiscal 1999
operating plan in which the Company has placed significant reliance on obtaining
additional outside financing. Management is actively pursuing additional debt
and equity financing from institutional investors as necessary and intends to
increase revenues and eventually achieve profitable operations. The financial
statements do not include any adjustments that might result from the outcome of
this uncertainty.

USE OF ESTIMATES

     The preparation of 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
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.

UNAUDITED INTERIM FINANCIAL INFORMATION

     The accompanying interim statements of operations and cash flows for the
nine months ended September 30, 1998 and 1999 are unaudited but include all
adjustments, consisting only of normal recurring adjustments, which the Company
considers necessary for a fair presentation of the results of operations and
cash flows for the nine months ended September 30, 1998 and 1999. The results of
operations and cash flows for the nine months ended September 30, 1999 are not
necessarily indicative of the results to be expected for the full year. The data
disclosed in these notes to the financial statements for these periods are
unaudited.

CERTAIN RISKS AND UNCERTAINTIES

     The Company's operating results are significantly dependent on the
Company's ability to market and develop its products. The life cycles of the
Company's products are difficult to estimate due in

                                      F-32

                                  ACUITY CORP.
                        (FORMERLY KNOWN AS ICHAT, INC.)

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

part to the effect of future product enhancements and competition. The inability
of the Company to successfully develop and market its products as a result of
competition or other factors would have a material adverse effect on the
Company's business, financial condition and results of operations.

     Concentrations of credit risk with respect to trade receivables are
generally limited due to the large number of customers, short payment terms, and
their dispersion across geographic areas. During 1998, sales to one customer was
$1,064,000, or 16%, with a related receivable balance of approximately $18,000.
Two other customers had receivable balances totaling approximately $590,000 at
December 31, 1998.

REVENUE RECOGNITION

     The Company's revenues are derived from product licensing revenues, and
fees for maintenance and support, training and consulting services. Product
licensing revenues are recognized after shipment of the product, provided
persuasive evidence of an arrangement exists, collection of the resulting
receivable is probable, the fee for the arrangement is fixed and determinable
and product returns are reasonably estimable. In instances where there are
customer acceptance criteria related to the Company's products or where there is
significant modification or customization of the Company's software products,
such revenue is deferred until the acceptance criteria have been satisfied or
the product has been modified for its intended purpose. Provisions for estimated
returns and warranty are recorded at the time products are shipped.

     Maintenance revenue consists of maintenance and renewal fees for providing
unspecified product updates on an if and when available basis and technical
support for the Company's software products. Maintenance revenues are recognized
ratably over the related service period, generally twelve months.

     Consulting revenue consists of training and consulting services provided to
the Company's customers. Training and consulting revenues are recognized as the
related services are performed.

     Customer advances and billed amounts due from customers in excess of
revenue recognized are recorded as deferred revenue.

ADVERTISING EXPENSES

     Advertising expenses consist primarily of costs incurred promoting the
Company's products, including public relations, trade shows, lead generation and
promotional materials. The Company expenses all advertising costs as incurred.
The Company's advertising expenses were approximately $1,035,189 for the year
ended December 31, 1997 and $687,080 for the year ended December 31, 1998.

CASH AND CASH EQUIVALENTS

     Cash and cash equivalents consist of cash on hand and on deposit at local
banks. The Company considers highly liquid investments with original maturities
of three months or less to be cash equivalents. Cash equivalents consist of
deposits in money market funds at December 31, 1997 and 1998 and at September
30, 1999.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

CONCENTRATIONS OF CREDIT RISK

     Financial instruments which potentially expose the Company to
concentrations of credit risk consist primarily of cash and cash equivalents and
accounts receivable. Management does not believe there is undue risk of loss
because in management's opinion, the financial institutions in which cash is
deposited are high credit quality institutions and the securities are
obligations of the United States government. However, cash and cash equivalents
exceeded FDIC insurance coverage limits. The Company has not experienced any
losses on its deposits. Although the Company does not require collateral on
accounts receivable, it does maintain reserves for credit losses.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of certain of the Company's financial instruments,
including cash and cash equivalents, accounts and notes receivable, accounts
payable and accrued liabilities, approximated fair value as of December 31, 1997
and 1998, because of the relatively short maturity of these instruments.

     The carrying amounts of the Company's borrowings under variable rate
long-term debt instruments approximate their fair value. The fair value of the
Company's other long-term obligation is estimated using discounted cash flow
analyses, based upon the Company's approximate incremental borrowing rates for
similar types of borrowing arrangements.

COMPUTER EQUIPMENT, FURNITURE AND FIXTURES

     Computer equipment, furniture and fixtures, software and leasehold
improvements are recorded at cost. Depreciation is provided using the
straight-line method over the estimated useful lives of the respective assets,
generally three to seven years. Expenditures that increase the value or extend
the life of the asset are capitalized, while the cost of maintenance and repairs
are expensed as incurred. Upon disposal, assets and related accumulated
depreciation are removed from the accounts and the related gain or loss is
included in operations.

RESEARCH AND DEVELOPMENT

     Research and development costs are charged to operations as incurred. The
Company capitalizes certain software development costs subsequent to the
establishment of technological feasibility. Based on the Company's product
development process, technological feasibility is established upon completion of
a working model. Costs incurred by the Company between completion of the working
model and the point at which the product is ready for general release have been
insignificant.

INCOME TAXES

     The Company accounts for income taxes in accordance with the liability
method. This method requires that deferred taxes be computed annually utilizing
the liability method and adjusted when new tax laws or rates are enacted.
Valuation allowances are established when necessary to reduce deferred tax
assets to the amounts expected to be realized. The Company recorded no income
tax expense for both the years ended December 31, 1997 or 1998 and has provided
a valuation allowance to fully offset the net deferred tax asset because the
realization of tax benefits associated with net operating loss carryforwards is
not assured.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

COMPREHENSIVE INCOME

     The Company has had no items of comprehensive income other than its net
loss for each of the two years in the period ended December 31, 1998.

RECLASSIFICATION

     Certain amounts previously reported in 1997 have been reclassified to
conform to the 1998 presentation.

Maker. During 1998, the note was forgiven by the Company as part of the
consideration given for a noncompete agreement between the officer and the
Company. The Company has received interest payments during the year ended
December 31, 1997 and 1998 of $4,320 and $2,160, respectively.

 4. LINE OF CREDIT:

     The Company has a revolving line of credit arrangement with a commercial
bank that enables the Company to borrow against eligible trade accounts
receivable up to a total of $2,500,000. As of December 31, 1998, the Company had
$721,240 outstanding under the revolving line of credit. The credit arrangement
contains certain financial covenants and restrictions as to various matters,
including the Company's net worth. The credit facility bears interest at prime

     The term loans and line of credit are collateralized by substantially all
the assets of the Company and contain certain financial covenants and
restrictions as to various matters, including the Company's net worth. At
December 31, 1998 the Company was not in compliance with its minimum quick ratio
and maximum loss covenants, which were waived by the bank in a letter dated
February 18, 1999. Should the Company continue to be in non-compliance with its
debt covenants, the bank has various remedies including the acceleration of the
due dates of principal payments that are currently classified as non-current
liabilities in the Company's financial statements.

Series D....................................  2,500,000      2,071,430      7,250,005
</TABLE>

     Each series of preferred stock is convertible into common stock at the
option of the holder on a one-for-one basis, subject to certain adjustments.
Each series of preferred stock will automatically convert upon the earliest of
(i) the closing date of an underwritten public offering of the Company's common
stock with aggregate proceeds of more than $18,000,000 and a per share offering
price of at least $9.00 or (ii) the date of an affirmative election of the
holders of 75% of the outstanding shares of preferred stock. The Company has
reserved 8,296,274 shares of common stock at December 31, 1998 to permit
conversion of the preferred stock in accordance with these terms.

     Holders of the preferred stock are entitled to one vote for each share of
common stock into which such shares may be converted. Each share of preferred
stock entitles the holder to receive noncumulative dividends, if and when
declared by the board of directors, prior to any dividend paid on the common
stock. Dividends, if any, on preferred stock shall be declared at an annual rate
of 10% of the original price paid per share. As of December 31, 1998, no
dividends have been declared. In the event of liquidation, the preferred stock
has preference over the common stock in the amount equal to the original issue
price plus declared but unpaid dividends.

STOCK OPTION PLAN

     During 1995, the Company adopted the 1995 Stock Option/Stock Issuance Plan
(the "Plan"), providing for two separate equity programs: (i) the Option Grant
Program providing for the granting of both incentive and non-statutory stock
options, as defined by the Internal Revenue Code, and (ii) the Stock Issuance
Program providing for the issuance of common stock directly, either through the
immediate purchase of such shares or as a bonus for services rendered to the
Company.

     The Plan, as amended, provides for a maximum number of common shares to be
optioned/issued of 3,950,000. Accordingly, the Company has reserved a sufficient
number of shares of common stock to permit exercise of options or issuance of
shares in accordance with the terms of the Plan. If an option expires or becomes
unexercisable for any reason, options related to the unpurchased shares become
available for grant. Each option granted under the Plan has a term of ten years
from the date of grant and an exercise price and vesting schedule as determined
by the Plan Administrator, at the date of grant, with the exception that
incentive stock options can not be granted for less than 100% of the fair market
value of the stock and non-statutory stock options can not be granted for less
than 110% of the fair

PRO FORMA STOCK BASED COMPENSATION

     The Company has applied Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees," and related interpretations, in
accounting for the Plan. Accordingly, no compensation expense has been
recognized for the Plan. Had compensation cost for the Plan been determined
based upon the fair value at the grant date for awards under the Plan consistent
with the methodology prescribed under Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation," such amount would
not have been materially different.

     The fair value of each option grant is estimated on the date of grant using
the minimum value method with the following weighted average assumptions used
for grants in 1997 and 1998: dividend yield of 0.0%, risk-free interest rate of
6.39% in 1997 and 6.00% in 1998 and expected lives of five years. Volatility of
the Company common stock underlying the options was not considered because the
Company's equity is not publicly traded as of December 31, 1998.

COMMON STOCK WARRANTS

     At December 31, 1998 the Company has outstanding warrants for the purchase
of 465,163 shares of its common stock at an exercise price of $2.75 per share.
These warrants are exercisable at any time through January 10, 1999. These
warrants were issued to holders of the Company's B-1 preferred stock as part of
a recapitalization of the Company in 1996. The warrants were issued in exchange
for warrants to purchase 465,153 shares of the Company's then authorized Series
B-3 preferred stock at an exercise price of $2.25 per share. The Company's
articles of incorporation were then amended to remove the Series B-3 preferred
stock from the Company's authorized capital.

 9. EMPLOYEE BENEFITS:

     The Company has established a 401(k) retirement savings plan for its full
time employees. All employees meeting minimum age requirements are eligible to
enroll in the Plan sixty days after commencement of employment. As of December
31, 1998, the Company has not provided matching contributions to employee
accounts.

10. INCOME TAXES:

     The Company has not recorded the tax benefits attributable to its taxable
losses incurred during the years ended December 1997 or 1998 due to the
uncertainty surrounding the recoverability of these deferred tax assets.

     At December 31, 1998 the Company had federal net operating loss
carryforwards of approximately $18,500,000 available to offset future taxable
income. The Company's federal operating loss carryforwards begin to expire
starting in the year 2011.

     As a result of ownership changes in prior years as defined by Internal
Revenue Code Section 382, approximately $4,365,000 in net operating loss
carryforwards are subject to a maximum annual utilization of approximately
$1,000,000 at December 31, 1998.

     The components of the net deferred tax asset are as follows at December 31,
1997 and 1998:

11. SUBSEQUENT EVENTS:

AUTHORIZATION AND SALE OF SERIES E CONVERTIBLE PREFERRED STOCK

     On February 22, 1999 the Company's board of directors designated 1,142,858
shares of the Company's authorized preferred stock as Series E preferred stock.
On February 25, 1999 the Company sold 785,715 shares of Series E convertible
preferred stock and warrants to purchase 392,858 shares of common stock for an
aggregate purchase price of $2,750,000. The warrants are exercisable through
February 27, 2001 at an exercise price of $0.70 per share. The warrants were
allocated $86,428 of the proceeds from the sale of the Series E convertible
preferred stock. The fair value of the warrants were calculated using the
Black-Scholes options model with the following assumptions: dividend yield of
0%, volatility of 50%, and a risk-free interest rate of 4.91%.

     Each share of Series E convertible preferred stock is entitled to receive
noncumulative dividends, when and if declared by the Company's board of
directors, at a rate of $0.35 per share per annum. Each share of Series E
preferred stock is convertible at the option of the holder into common shares of
the Company on a one for one basis, subject to certain anti-dilution provisions
as described in the Company's articles of incorporation. Conversion of the
Series E preferred stock is automatic upon either i) the sale of the Company's
common stock in a firmly underwritten public offering in which the offering
price is not less than $9.00 per share and which results in aggregate proceeds
to the Company of at least $18,000,000 net of underwriting discounts,
commissions and fees, or ii) the written consent of 75% of the outstanding
shares of Series E preferred stock.

     Upon any liquidation, dissolution or winding up of the Company, the Series
E preferred shareholders are entitled to a liquidation preference of $3.50 per
share plus all declared but unpaid dividends thereon.

SALE OF EXCLUSIVE TECHNOLOGY LICENSE

     In March 1999, the Company entered into an agreement to sell exclusive
source and object code licenses for the ichat software. Under the terms of the
agreement, the Company received $1.3 million in cash at the time of purchase,
notes receivable in the principal amounts of $1 million due on June 30, 1999,
$700,000 due on December 15, 1999, and $600,000 of preferred stock from the next
issuance of the purchaser. In connection with this sale, the Company entered
into a commission agreement with a stockholder under which the stockholder will
receive a total of $354,665 for negotiating the sale of these assets. At
September 30, 1999 the Company had a remaining balance due to the stockholder of
$166,968 related to this transaction. The amount has been disclosed as accrued
expenses -- related party.

12. SUBSEQUENT EVENTS (UNAUDITED)

     On September 10, 1999 the Company entered into an agreement to have all of
its outstanding capital stock acquired by Quintus Corporation.

     In September, 1999 the Company's board of directors designated and sold
482,625 shares of the Company's authorized preferred stock as Series F
convertible preferred stock for an aggregate purchase price of $1,250,000. The
board also issued warrants to purchase 178,570 shares of the Company's common
stock at an exercise price of $0.70 per share through September, 2001. The

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

warrants were allocated $546,424 of the proceeds from the sale of the Series F
convertible preferred stock. The fair value of the warrants were calculated
using the Black-Scholes option model with the following assumptions: dividend
yield of 0%, volatility of 50%, and a risk-free interest rate of 4.91%. The fair
value of the Series F convertible preferred stock and the warrants to purchase
common stock exceeded the $1,250,000 in gross proceeds received by the Company
by $1,072,144. As a result, the Company has recorded a deemed dividend related
to this transaction.

     On September 2, 1999 the Company's board of directors extended the
expiration date of the warrants that were set to expire on January 10, 1999 to
January 10, 2000. In relation to this extension, the Company has recorded a
dividend to the Company's current stockholders that are also the holders of the
Company's warrants in the amount of $165,812. The fair value of the extension of
the warrants was calculated using the Black-Scholes option model using the
following assumptions: dividend yield of 0%, volatility of 50%, and a risk-free
interest rate of 5.63%.

                         YEAR ENDED MARCH 31, 1999 AND
                      SIX MONTHS ENDED SEPTEMBER 30, 1999


     On September 10, 1999, Quintus entered into an Agreement and Plan of
Reorganization to acquire all of the outstanding shares and assume the
outstanding options and warrants of Acuity Corp. (Acuity), a company
specializing in providing Web based customer interaction software. Quintus will
issue a total of approximately 4,551,441 shares comprised of 1,546,586 shares of
common stock valued at approximately $12,760,000, approximately 3,004,855 shares
of Series G preferred stock valued at approximately $24,790,000, and assume
approximately 877,955 options and 323,927 warrants to purchase common and
preferred stock valued at approximately $7,670,000. The aggregate purchase
price, including approximately $300,000 of transaction costs not paid in stock,
will be approximately $45,520,000. The agreement is subject to shareholder
approval and will close prior to the effectiveness of this offering.


     The acquisition will be accounted for using the purchase method of
accounting. The aggregate purchase price will be allocated to the assets and
liabilities acquired based on their fair value. The total consideration is
expected to exceed the fair value of the net assets acquired by approximately
$45,820,000, which represents the following estimated intangible assets:

     The acquired technology provides a comprehensive framework to manage
internet-based customer interactions, including Web self-service, Web chat,
browser-based collaboration and Web-call back. The in-process research and
development represents technology which has not yet reached technological
feasibility and does not have alternative future uses. This amount will be
charged to Quintus' operations in the period in which the transaction is
consummated. The in-process research and development was identified and valued
through extensive interviews and discussions with Quintus and Acuity management
and the analysis of data provided by Acuity concerning developmental products,
their respective stage of development, the time and resources needed to complete
them, their expected income generating ability, target markets and associated
risks. The Income Approach, which includes an analysis of the markets, cash
flows, and risks associated with achieving such cash flows, was the primary
technique utilized in valuing each in-process research and development project.
A portion of the purchase price was allocated to the developmental projects
based on the appraised fair values of such projects. The allocation of the
purchase price is preliminary and will not be finalized until the transaction is
consummated.


     The accompanying pro forma financial statements are presented in accordance
with Article 11 of Regulation S-X.

     The unaudited pro forma condensed combining balance sheet has been prepared
as if the acquisition was completed as of September 30, 1999. The unaudited pro
forma condensed combining

                                      F-44

statements of operations were prepared as if the acquisition was completed at
the beginning of the periods presented. To prepare the pro forma unaudited
condensed combining statements of operations, the Quintus statement of
operations for the year ended March 31, 1999 has been combined with the
statement of operations of Acuity for the year ended December 31, 1998. Acuity's
revenue of $6,719,000 for the year ended December 31, 1998 includes $5,504,000
of revenue related to a product line that was sold during the first quarter of
1999. Also, the statement of operations of both Quintus and Acuity have been
combined for the six months ended September 30, 1999. The statement of
operations of Acuity for the quarter ended March 31, 1999 which has been
excluded from these pro forma financial statements included revenues, operating
loss and net income of $765,000, $2.4 million, and $321,000, respectively. This
method of combining the companies is only for presentation of pro forma
unaudited condensed combining financial statements. Actual statements of
operations of the companies will be combined from the effective date of the
acquisition.


     The pro forma earnings per share disclosed in the unaudited pro forma
condensed statements of operations have assumed the conversion of the 3,004,855
shares of preferred stock to be issued in connection with the acquisition into
common stock since these shares will automatically convert upon the
effectiveness of the Company's initial public offering.


     The unaudited pro forma condensed combining financial statements should be
read in conjunction with the historical financial statements of Quintus and
Acuity.

     The unaudited pro forma condensed combining statements of operations do not
include the one-time $3.0 million charge for purchased in-process technology
arising from this acquisition, as it is a material nonrecurring charge. This
charge will be included in the actual consolidated statement of operations of
Quintus when the acquisition is consummated.

          7. Reflects the issuance of approximately 4,551,442 shares for the
     acquisition of Acuity. This calculation assumes the conversion of 3,004,855
     shares of preferred stock to be issued in connection with the acquisition
     into common stock since these shares will automatically convert upon the
     effectiveness of the Company's initial public offering.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law authorizes a court to
award or a corporation's board of directors to grant indemnification to
directors and officers, including reimbursement for expenses incurred, in terms
sufficiently broad to permit such indemnification under certain circumstances
for liabilities arising under the Securities Act of 1933, as amended (the
"Securities Act"). Article VII, Section 6, of the Registrant's bylaws provides
for mandatory indemnification of its directors and permissible indemnification
of officers and employees to the maximum extent permitted by the Delaware
General Corporation Law. The Registrant's certificate of incorporation provides
that, pursuant to Delaware law, its directors shall not be liable for monetary
damages for breach of the directors' fiduciary duty as directors to Quintus and
its stockholders. This provision in the certificate of incorporation does not
eliminate the directors' fiduciary duty, and in appropriate circumstances
equitable remedies such as injunctive or other forms of non-monetary relief will
remain available under Delaware law. In addition, each director will continue to
be subject to liability for breach of the director's duty of loyalty to Quintus
for acts or omissions not in good faith or involving intentional misconduct, for
knowing violations of law, for actions leading to improper personal benefit to
the director, and for payment of dividends or approval of stock repurchases or
redemptions that are unlawful under Delaware law. The provision also does not
affect a director's responsibilities under any other law, such as the federal
securities laws or state or federal environmental laws. The Registrant has
entered into indemnification agreements with its officers and directors, a form
of which is attached as Exhibit 10.1 hereto and incorporated herein by
reference. The indemnification agreements provide the Registrant's officers and
directors with further indemnification to the maximum extent permitted by the
Delaware General Corporation Law. Reference is made to Section 7 of the
Underwriting Agreement contained in Exhibit 1.1 hereto, indemnifying officers
and directors of the Registrant against certain liabilities.

offering or transactions under compensation benefit plans and contracts relating

Securities Act as a security issued after a ruling by an authorized authority
upon the fairness of the transaction's terms and conditions. With regard to the
sales of securities exempted by Section 4(2) of the Securities Act, the
recipients of securities in each transaction represented their intentions to
acquire the securities for investment only and not with a view to or for sale in

     Schedules not listed above have been omitted because the information
required to be set forth therein is not applicable or is shown in the financial
statements or notes thereto.

ITEM 17. UNDERTAKINGS

     The Registrant hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the Delaware General Corporation Law, the Certificate of
Incorporation or the Bylaws of the Registrant, the Underwriting Agreement, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act, and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer,
or controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered hereunder, the Registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

     The Registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of Prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of Prospectus filed by the Registrant pursuant to

                                      II-4
<PAGE>   135

     Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to
     be part of this Registration Statement as of the time it was declared
     effective.

          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of Prospectus shall
     be deemed to be a new Registration Statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

Ladies and Gentlemen:

     Quintus Corporation, a Delaware corporation (the "COMPANY"), proposes to
issue and sell 4,000,000 SHARES of its Common Stock, $0.001 par value, (the
"FIRM SHARES") to the several underwriters named in Schedule I hereto (the
"UNDERWRITERS"). The Company also proposes to issue and sell to the several
Underwriters not more than an additional 600,000 SHARES of its Common Stock,
$0.001 par value, (the "ADDITIONAL SHARES") if requested by the Underwriters as
provided in Section 2 hereof. The Firm Shares and the Additional Shares are
hereinafter referred to collectively as the "SHARES". The shares of common stock
of the Company to be outstanding after giving effect to the sales contemplated
hereby are hereinafter referred to as the "COMMON STOCK".


                                       1

     SECTION 1. Registration Statement and Prospectus. The Company has prepared
and filed with the Securities and Exchange Commission (the "COMMISSION") in
accordance with the provisions of the Securities Act of 1933, as amended, and
the rules and regulations of the Commission thereunder (collectively, the
"ACT"), a registration statement on Form S-1, including a prospectus, relating
to the Shares. The registration statement, as amended at the time it became
effective, including the information (if any) deemed to be part of the
registration statement at the time of effectiveness pursuant to Rule 430A under
the Act, is hereinafter referred to as the "REGISTRATION STATEMENT"; and the
prospectus in the form first used to confirm sales of Shares is hereinafter
referred to as the "PROSPECTUS". If the Company has filed or is required
pursuant to the terms hereof to file a registration statement pursuant to Rule
462(b) under the Act registering additional shares of Common Stock (a "RULE
462(B) REGISTRATION STATEMENT"), then, unless otherwise specified, any reference
herein to the term "Registration Statement" shall be deemed to include such Rule
462(b) Registration Statement.

     SECTION 2. Agreements to Sell and Purchase and Lock-Up Agreements. On the
basis of the representations and warranties contained in this Agreement, and
subject to its terms and conditions, the Company agrees to issue and sell, and
each Underwriter agrees, severally and not jointly, to purchase from the Company
at a price per Share of $______ (the "PURCHASE PRICE") the number of Firm Shares
set forth opposite the name of such Underwriter in Schedule I hereto.

     On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company agrees to issue
and sell the Additional Shares and the Underwriters shall have the right to
purchase, severally and not jointly, up to 600,000 ADDITIONAL Shares from the
Company at the Purchase Price. Additional Shares may be purchased solely for the
purpose of covering over-allotments made in connection with the offering of the
Firm Shares. The Underwriters may exercise their right to purchase Additional
Shares in whole or in part from time to time by giving written notice thereof to
the Company within 30 days after the date of this Agreement. You shall give any
such notice on behalf of the Underwriters and such notice shall specify the
aggregate number of Additional Shares to be purchased pursuant to such exercise
and the date for payment and delivery thereof, which date shall be a business
day (i) no earlier than two business days after such notice has been given (and,
in any event, no earlier than the Closing Date (as hereinafter defined)) and
(ii) no later than ten business days after such notice has been given. If any
Additional Shares are to be purchased, each Underwriter, severally and not
jointly, agrees to purchase from the Company the number of Additional Shares
(subject to such adjustments to eliminate fractional shares as you may
determine) which bears the same proportion to the total number of Additional
Shares to be purchased from the Company as the number of Firm Shares set forth
opposite the name of such Underwriter in Schedule I bears to the total number of
Firm Shares.

loan agreement, mortgage, lease or other agreement or instrument that is
material to the Company and its subsidiaries, taken as a whole, to which the
Company or any of its subsidiaries is a party or by which the Company or any of
its subsidiaries or their respective property is bound.

     (j)  The execution, delivery and performance of this Agreement by the
Company, the compliance by the Company with all the provisions hereof and the

including, without limitation, under any applicable Environmental Laws, as are
necessary to own, lease, license and operate its respective properties and to
conduct its business, except where the failure to have any such Authorization or

Material Adverse Effect. Each such Authorization is valid and in full force and
effect and each of the Company and its subsidiaries is in compliance with all
the terms and conditions thereof and with the rules and regulations of the
authorities and governing bodies having jurisdiction with respect thereto; and
no event has occurred (including, without limitation, the receipt of any notice
from any authority or governing body) which allows or, after notice or lapse of
time or both, would allow, revocation, suspension or termination of any such
Authorization or results or, after notice or lapse of time or both, would result
in any other impairment of the rights of the holder of any such Authorization;
except where such failure to be valid and in full force and effect or to be in
compliance, or the occurrence of any such event would not, singly or in the
aggregate, have a Material Adverse Effect.

     (n)  There are no costs or liabilities associated with Environmental Laws
(including, without limitation, any capital or operating expenditures required
for clean-up, closure of properties or compliance with Environmental Laws or any
Authorization, any related constraints on operating activities and any potential
liabilities to third parties) which would, singly or in the aggregate, have a
Material Adverse Effect.

     (o)  This Agreement has been duly authorized, executed and delivered by the
Company.

     (p)  Deloitte & Touche LLP are independent public accountants with respect
to the Company and its subsidiaries as required by the Act.

     (q)  The consolidated financial statements included in the Registration

simple to all real property and good and marketable title to all personal

<PAGE>   13

property and do not interfere with the use made and proposed to be made of such

secrets and other unpatented and/or unpatentable proprietary or confidential
information, systems or procedures), trademarks, service marks and trade names
("INTELLECTUAL PROPERTY") currently employed by them in connection with the
business now operated by them except where the failure to own or possess or
otherwise be able to acquire such Intellectual Property would not, singly or in
the aggregate, have a Material Adverse Effect ; and neither the Company nor any

     SECTION 7. Indemnification. 1) The Company agrees to indemnify and hold
harmless each Underwriter, its directors, its officers and each person, if any,
who controls any Underwriter within the meaning of Section 15 of the Act or
Section 20 of the Securities Exchange Act of 1934, as amended (the "EXCHANGE
ACT"), from and against any and all losses, claims, damages, liabilities and
judgments (including, without limitation, any legal or other expenses incurred
in connection with investigating or defending any matter, including any action,
that could give rise to any such losses, claims, damages, liabilities or
judgments) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement (or any amendment
thereto), the Prospectus (or any amendment or supplement thereto) or any
preliminary prospectus, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or judgments are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information relating
to any Underwriter furnished in writing to the Company by such Underwriter
through you expressly for use therein; provided, however, that the foregoing
indemnity agreement with respect to any preliminary prospectus shall not inure
to the benefit of any Underwriter who failed to deliver a Prospectus, as then
amended or supplemented, (so long as the Prospectus and any amendments or
supplements thereto was provided by the Company to the several Underwriters in
the requisite quantity and on a timely basis to permit proper delivery on or
prior to the Closing Date) to the person asserting any losses, claims, damages,
liabilities or judgments caused by any untrue statement or alleged untrue
statement of a material fact contained in such preliminary prospectus, or caused
by any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, if
such material misstatement or omission or alleged material misstatement or
omission was cured in the Prospectus, as so amended or supplemented, and such
Prospectus was required by law to be delivered at or prior to the written
confirmation of sale to such person.

     (a)  Each Underwriter agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors, its officers who sign the Registration
Statement and each person, if any, who controls the Company within the meaning
of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent
as the foregoing indemnity from the Company to such Underwriter but only with
reference to information relating to such Underwriter furnished in writing to
the Company by such Underwriter through you expressly for use in the
Registration Statement (or any amendment thereto), the Prospectus (or any
amendment or supplement thereto) or any preliminary prospectus.

     (b)  In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 7(a) or 7(b) (the
"indemnified


                                       14

<PAGE>   15

party"), the indemnified party shall promptly notify the person against whom
such indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party shall assume the defense of such action, including the
employment of counsel reasonably satisfactory to the indemnified party and the
payment of all reasonable fees and expenses of such counsel, as incurred (except
that in the case of any action in respect of which indemnity may be sought
pursuant to both Sections 7(a) and 7(b), the Underwriter shall not be required
to assume the defense of such action pursuant to this Section 7(c), but may
employ separate counsel and participate in the defense thereof, but the fees and
expenses of such counsel, except as provided below, shall be at the expense of
such Underwriter). Any indemnified party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of the indemnified party
unless (i) the employment of such counsel shall have been specifically
authorized in writing by the indemnifying party, (ii) the indemnifying party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the indemnified party or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party).
In any such case, the indemnifying party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) for all indemnified parties and all such fees and
expenses shall be reimbursed as they are incurred. Such firm shall be designated
in writing by Donaldson, Lufkin & Jenrette Securities Corporation, in the case
of parties indemnified pursuant to Section 7(a), and by the Company, in the case
of parties indemnified pursuant to Section 7(b). The indemnifying party shall
indemnify and hold harmless the indemnified party from and against any and all
losses, claims, damages, liabilities and judgments by reason of any settlement
of any action (i) effected with the written consent of the indemnifying party or
(ii) effected without its written consent if the settlement is entered into more
than thirty business days after the indemnifying party shall have received a
WRITTEN request from the indemnified party for reimbursement for the fees and
expenses of counsel (in any case where such fees and expenses are at the expense
of the indemnifying party) and, prior to the date of such settlement, the
indemnifying party shall have failed to comply with such reimbursement request.
No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement or compromise of, or consent to the
entry of judgment with respect to, any pending or threatened action in respect
of which the indemnified party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the indemnified
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability on claims that
are or could have been the subject matter of such action and (ii) does not
include a


                                       15

<PAGE>   16

statement as to or an admission of fault, culpability or a failure to act, by or
on behalf of the indemnified party.

     (c)  To the extent the indemnification provided for in this Section 7 is
unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Underwriters on the other hand from the offering
of the Shares or (ii) if the allocation provided by clause 7(d)(i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause 7(d)(i) above but also the
relative fault of the Company on the one hand and the Underwriters on the other
hand in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and the Underwriters on the other hand shall be deemed to be in the
same proportion as the total net proceeds from the offering (after deducting
underwriting discounts and commissions, but before deducting expenses) received
by the Company, and the total underwriting discounts and commissions received by
the Underwriters, bear to the total price to the public of the Shares, in each
case as set forth in the table on the cover page of the Prospectus. The relative
fault of the Company on the one hand and the Underwriters on the other hand
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
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

     The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 7(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 in the immediately preceding paragraph. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses incurred by such indemnified party in
connection with investigating or defending any matter, including any action,
that could have given rise to such losses, claims, damages, liabilities or
judgments. Notwithstanding the provisions of this Section 7, no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the Shares underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the


                                       16

<PAGE>   17

Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. The Underwriters' obligations to contribute
pursuant to this Section 7(d) are several in proportion to the respective number
of Shares purchased by each of the Underwriters hereunder and not joint.

     (d)  The remedies provided for in this Section 7 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

     SECTION 8. Indemnification of QIU. 2) The Company agrees to indemnify and
hold harmless the QIU, its directors, its officers and each person, if any, who
controls the QIU within the meaning of Section 15 of the Act or Section 20 of
the Exchange Act, from and against any and all losses, claims, damages,
liabilities and judgments (including, without limitation, any legal or other
expenses incurred in connection with investigating or defending any matter,
including any action, that could give rise to any such losses, claims, damages,
liabilities or judgments) related to, based upon or arising out of (i) any
untrue statement or alleged untrue statement of a material fact contained in the
Registration Statement (or any amendment thereto), the Prospectus (or any
amendment or supplement thereto) or any preliminary prospectus, or any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, EXCEPT
INSOFAR AS SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR JUDGMENTS ARE CAUSED BY
ANY SUCH UNTRUE STATEMENT OR OMISSION OR ALLEGED UNTRUE STATEMENT OR OMISSION
BASED UPON INFORMATION RELATING TO THE QIU FURNISHED IN WRITING BY THE QIU
THROUGH YOU EXPRESSLY FOR USE THEREIN; or (ii) the QIU's activities as QIU under
its engagement pursuant to Section 2 hereof, except in the case of this clause
(ii) insofar as any such losses, claims, damages, liabilities or judgments are
found in a final judgment by a court of competent jurisdiction, not subject to
further appeal, to have resulted solely from the willful misconduct or gross
negligence of the QIU.

     (a)  In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 8(a) (the "QIU INDEMNIFIED
PARTY"), the QIU Indemnified Party shall promptly notify the Company in writing
and the Company shall assume the defense of such action, including the
employment of counsel reasonably satisfactory to the QIU Indemnified Party and
the payment of all fees and expenses of such counsel, as incurred. Any QIU
Indemnified Party shall have the right to employ separate counsel in any such
action and participate in the defense thereof, but the reasonable fees and
expenses of such counsel shall be at the expense of the QIU Indemnified Party
unless (i) the employment of such counsel shall have been specifically
authorized in writing by the Company, (ii) the Company shall have failed to
assume the defense of such action or employ counsel reasonably satisfactory to
the QIU Indemnified Party or (iii) the named parties to any such action
(including any impleaded parties) include both the QIU Indemnified Party and the
Company, and the QIU Indemnified Party shall have been advised by such counsel
that there may be one or more legal


                                       17

<PAGE>   18

defenses available to it which are different from or additional to those
available to the Company (in which case the Company shall not have the right to
assume the defense of such action on behalf of the QIU Indemnified Party). In
any such case, the Company shall not, in connection with any one action or
separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
fees and expenses of more than one separate firm of attorneys (in addition to
any local counsel) for all QIU Indemnified Parties, which firm shall be
designated by the QIU, and all such fees and expenses shall be reimbursed as
they are incurred. The Company shall indemnify and hold harmless the QIU
Indemnified Party from and against any and all losses, claims, damages,
liabilities and judgments by reason of any settlement of any action (i) effected
with the written consent of the Company or (ii) effected without its written
consent if the settlement is entered into more than thirty business days after
the Company shall have received a WRITTEN request from the QIU Indemnified Party
for reimbursement for the fees and expenses of counsel (in any case where such
fees and expenses are at the expense of the Company) and, prior to the date of
such settlement, the Company shall have failed to comply with such reimbursement
request. The Company shall not, without the prior written consent of the QIU
Indemnified Party, effect any settlement or compromise of, or consent to the
entry of judgment with respect to, any pending or threatened action in respect
of which the QIU Indemnified Party is or could have been a party and indemnity
or contribution may be or could have been sought hereunder by the QIU
Indemnified Party, unless such settlement, compromise or judgment (i) includes
an unconditional release of the QIU Indemnified Party from all liability on
claims that are or could have been the subject matter of such action and (ii)
does not include a statement as to or an admission of fault, culpability or a
failure to act, by or on behalf of the QIU Indemnified Party.

     (b)  To the extent the indemnification provided for in this Section 8 is
unavailable to a QIU Indemnified Party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then the Company,
in lieu of indemnifying such QIU Indemnified Party, shall contribute to the
amount paid or payable by such QIU Indemnified Party as a result of such losses,
claims, damages, liabilities and judgments (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the QIU on the other hand from the offering of the Shares or (ii) if
the allocation provided by clause 8(c)(i) above is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause 8(c)(i) above but also the relative fault of the
Company on the one hand and the QIU on the other hand in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities or judgments, as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the QIU on the other hand shall be deemed to be in the same proportion as
the total net proceeds from the offering (before deducting expenses) received by
the Company as set forth in the table on the cover page of the Prospectus, and
the fee received by the QIU pursuant to Section 2 hereof, bear to the sum of
such total net proceeds and such fee. The relative fault of the Company on the
one hand and


                                       18

<PAGE>   19

the QIU on the other hand 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 QIU and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission and whether the QIU's activities as QIU under its engagement pursuant
to Section 2 hereof involved any willful misconduct or gross negligence on the
part of the QIU.

     The Company and the QIU agree that it would not be just and equitable if
contribution pursuant to this Section 8(c) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by a QIU Indemnified Party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses incurred by such QIU Indemnified Party
in connection with investigating or defending any matter, including any action,
that could have given rise to such losses, claims, damages, liabilities or
judgments. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     (c)  The remedies provided for in this Section 8 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
QIU Indemnified Party at law or in equity.

     SECTION 9. Conditions of Underwriters' Obligations. The several obligations
of the Underwriters to purchase the Firm Shares under this Agreement are subject
to the satisfaction of each of the following conditions:

     (a)  All the representations and warranties of the Company contained in
this Agreement shall be true and correct on the Closing Date with the same force
and effect as if made on and as of the Closing Date.

     (b)  If the Company is required to file a Rule 462(b) Registration
Statement after the effectiveness of this Agreement, such Rule 462(b)
Registration Statement shall have become effective by 10:00 P.M., New York City
time, on the date of this Agreement; and no stop order suspending the
effectiveness of the Registration Statement shall have been issued and no
proceedings for that purpose shall have been commenced or shall be pending
before or threatened by the Commission.

     (c)  You shall have received on the Closing Date a certificate dated the
Closing Date, signed by Alan K. Anderson and Susan Salvesen, in their capacities
as the Chief Executive Officer and Chief Financial Officer of the Company,
confirming the matters set forth in Sections 6(t), 9(a) and 9(b) and that the
Company has complied with


                                       19

<PAGE>   20

all of the agreements and satisfied all of the conditions herein contained and
required to be complied with or satisfied by the Company on or prior to the
Closing Date.

     (d)  Since the respective dates as of which information is given in the
Prospectus other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement,
except for any amendments or supplements of which you had notice and to which
you did not object prior to their filing with the Commission), (i) there shall
not have occurred any change or any development involving a prospective change
in the condition, financial or otherwise, or the earnings, business, management

shall not have been any change or any development involving a prospective change
in the capital stock or in the long-term debt of the Company or any of its
subsidiaries and (iii) neither the Company nor any of its subsidiaries shall
have incurred any liability or obligation, direct or contingent, the effect of
which, in any such case described in clause 9(d)(i), 9(d)(ii) or 9(d)(iii), in
your judgment, is material and adverse and, in your judgment, makes it
impracticable to market the Shares on the terms and in the manner contemplated
in the Prospectus.

     are not so described or filed as required;

          (xiii) the Company is not and, after giving effect to the offering
     and sale of the Shares and the application of the proceeds thereof as
     described in the Prospectus, will not be, an "investment company" as such
     term is defined in the Investment Company Act of 1940, as amended;

     with the Act, (B) such counsel has no reason to believe that at the time
     the Registration Statement became effective, the Registration Statement and

     contained any untrue statement of a material


                                       22

<PAGE>   23

     fact or omitted to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading and (C) such
     counsel has no reason to believe that at the time the Registration
     Statement became effective or on the date of this Agreement the Prospectus,
     as amended or supplemented, if applicable (except for the financial
     statements and other financial data, as aforesaid) contains any untrue
     statement of a material fact or omits to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading.

     (f)  You shall have received on the Closing Date an opinion, dated the
Closing Date, of Wilson Sonsini Goodrich & Rosati, Professional Corporation,

CAPTIONS "Description of Capital Stock" and "Underwriting" CONSTITUTE A SUMMARY
OF THE LEGAL MATTERS, DOCUMENTS OR PROCEEDINGS REFERRED TO THEREIN) AND
9(e)(xv).

     In giving such opinions with respect to the matters covered by the last
paragraph of Section 9(e) Gunderson Dettmer Stough Villeneuve Franklin &
Hachigian, LLP and Wilson Sonsini Goodrich & Rosati, Professional Corporation,
may state that their opinion and belief are based upon their participation in
the preparation of the Registration Statement and Prospectus and any amendments
or supplements thereto and review and discussion of the contents thereof, but
are without independent check or verification except as specified.

     (g)  You shall have received, on each of the date hereof and the Closing
Date, a letter dated the date hereof or the Closing Date, as the case may be, in
form and substance reasonably satisfactory to you, from Deloitte & Touche LLP,
independent public accountants, containing the information and statements of the
type ordinarily included in accountants' "comfort letters" to Underwriters with
respect to the financial statements and certain financial information contained
in the Registration Statement and the Prospectus.

     (h)  The Company shall have delivered to you the agreements specified in
Section 2 hereof which agreements shall be in full force and effect on the
Closing Date.

     (i)  The Shares shall have been duly listed for quotation on the Nasdaq
National Market.

     (j)  The Company shall not have failed on or prior to the Closing Date to
perform or comply with any of the agreements herein contained and required to be

Shares hereunder are subject to the delivery to you on the applicable Option
Closing Date of such documents as you may reasonably request with respect to the
good standing of the


                                       23

<PAGE>   24

mpany, the due authorization and issuance of such Additional Shares and other
matters related to the issuance of such Additional Shares.

     SECTION 10. Effectiveness of Agreement and Termination. This Agreement
shall become effective upon the execution and delivery of this Agreement by the
parties hereto.

     This Agreement may be terminated at any time on or prior to the Closing
Date by you by written notice to the Company if any of the following has
occurred: (i) any outbreak or escalation of hostilities or other national or
international calamity or crisis or change in economic conditions or in the
financial markets of the United States or elsewhere that, in your judgment, is
material and adverse and, in your judgment, makes it impracticable to market the
Shares on the terms and in the manner contemplated in the Prospectus, (ii) the
suspension or material limitation of trading in securities or other instruments
on the New York Stock Exchange, the American Stock Exchange, the Chicago Board
of Options Exchange, the Chicago Mercantile Exchange, the Chicago Board of Trade
or the Nasdaq National Market or limitation on prices for securities or other
instruments on any such exchange or the Nasdaq National Market, (iii) the
suspension of trading of any securities of the Company on any exchange or in the
over-the-counter market, (iv) the enactment, publication, decree or other
promulgation of any federal or state statute, regulation, rule or order of any
court or other governmental authority which in your opinion materially and
adversely affects, or will materially and adversely affect, the business,
prospects, financial condition or results of operations of the Company and its
subsidiaries, taken as a whole, (v) the declaration of a banking moratorium by
either federal or New York State authorities or (vi) the taking of any action by
any federal, state or local government or agency in respect of its monetary or
fiscal affairs which in your opinion has a material adverse effect on the
financial markets in the United States.

     If on the Closing Date or on an Option Closing Date, as the case may be,
any one or more of the Underwriters shall fail or refuse to purchase the Firm
Shares or Additional Shares, as the case may be, which it has or they have
agreed to purchase hereunder on such date and the aggregate number of Firm
Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase is not more
than one-tenth of the total number of Firm Shares or Additional Shares, as the
case may be, to be purchased on such date by all Underwriters, each
non-defaulting Underwriter shall be obligated severally, in the proportion which
the number of Firm Shares set forth opposite its name in Schedule I bears to the
total number of Firm Shares which all the non-defaulting Underwriters have
agreed to purchase, or in such other proportion as you may specify, to purchase
the Firm Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase on such
date; provided that in no event shall the number of Firm Shares or Additional
Shares, as the case may be, which any Underwriter has agreed to purchase
pursuant to Section 2 hereof be increased pursuant to this Section 9 by an


                                       24

<PAGE>   25

amount in excess of one-ninth of such number of Firm Shares or Additional
Shares, as the case may be, without the written consent of such Underwriter. If
on the Closing Date any Underwriter or Underwriters shall fail or refuse to
purchase Firm Shares and the aggregate number of Firm Shares with respect to
which such default occurs is more than one-tenth of the aggregate number of Firm
Shares to be purchased by all Underwriters and arrangements satisfactory to you
and the Company for purchase of such Firm Shares are not made within 48 hours
after such default, this Agreement will terminate without liability on the part
of any non-defaulting Underwriter and the Company. In any such case which does
not result in termination of this Agreement, either you or the Company shall
have the right to postpone the Closing Date, but in no event for longer than
seven days, in order that the required changes, if any, in the Registration
Statement and the Prospectus or any other documents or arrangements may be
effected. If, on an Option Closing Date, any Underwriter or Underwriters shall
fail or refuse to purchase Additional Shares and the aggregate number of
Additional Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Additional Shares to be purchased on such
date, the non-defaulting Underwriters shall have the option to (i) terminate
their obligation hereunder to purchase such Additional Shares or (ii) purchase
not less than the number of Additional Shares that such non-defaulting
Underwriters would have been obligated to purchase on such date in the absence
of such default. Any action taken under this paragraph shall not relieve any
defaulting Underwriter from liability in respect of any default of any such
Underwriter under this Agreement.

     SECTION 11. Miscellaneous. Notices given pursuant to any provision of this
Agreement shall be addressed as follows: (i) if to the Company, to Quintus
Corporation, 47212 Mission Falls Court, Fremont, California 94539, Attention:
Chief Executive Officer, and (ii) if to any Underwriter or to you, to you c/o
Donaldson, Lufkin & Jenrette Securities Corporation, 277 Park Avenue, New York,
New York 10172, Attention: Syndicate Department, or in any case to such other
address as the person to be notified may have requested in writing.

     The respective indemnities, contribution agreements, representations,
warranties and other statements of the Company and the several Underwriters set
forth in or made pursuant to this Agreement shall remain operative and in full
force and effect, and will survive delivery of and payment for the Shares,
regardless of (i) any investigation, or statement as to the results thereof,
made by or on behalf of any Underwriter, the officers or directors of any
Underwriter, any person controlling any Underwriter, any QIU Indemnified Party,
the Company, the officers or directors of the Company or any person controlling
the Company, (ii) acceptance of the Shares and payment for them hereunder and
(iii) termination of this Agreement.

     If for any reason the Shares are not delivered by or on behalf of the
Company as provided herein (other than as a result of any termination of this
Agreement pursuant to Section 10), the Company agrees to reimburse the several
Underwriters for all out-of-pocket expenses (including the fees and
disbursements of counsel) incurred by them.


                                       25

<PAGE>   26

twithstanding any termination of this Agreement, the Company shall be liable for
all expenses which it has agreed to pay pursuant to Section 5(i) hereof. The
Company also agrees to reimburse the several Underwriters, their directors and
officers, any persons controlling any of the Underwriters and the QUI
Indemnified Parties for any and all fees and expenses (including, without
limitation, the fees disbursements of counsel) incurred by them in connection
with enforcing their rights hereunder (including, without limitation, pursuant
to Section 7 hereof).

     Except as otherwise provided, this Agreement has been and is made solely
for the benefit of and shall be binding upon the Company, the Underwriters, the
Underwriters' directors and officers, any controlling persons referred to
herein, the QIU Indemnified Parties, the Company's directors and the Company's
officers who sign the Registration Statement and their respective successors and
assigns, all as and to the extent provided in this Agreement, and no other
person shall acquire or have any right under or by virtue of this Agreement. The
term "successors and assigns" shall not include a purchaser of any of the Shares
from any of the several Underwriters merely because of such purchase.

     This Agreement shall be governed and construed in accordance with the laws
of the State of New York.

     This Agreement may be signed in various counterparts which together shall
constitute one and the same instrument.
