ITEM 1. BUSINESS
- ----------------

GENERAL

Davox Corporation ("Davox" or the "Company") and its subsidiaries develop,
market, support and service software solutions for the contact center
marketplace.  Davox was founded in 1981 on a simple principal: provide solutions
that will enable call centers to optimize agent productivity and effectively
manage calling campaigns in order to provide superior customer service and
satisfaction.   Since then, Davox has become a recognized leader in the customer
interaction management marketplace. Through its direct sales force and third-
party distribution channels, Davox provides a full range of customer interaction
management solutions to businesses involved in mission-critical customer contact
activities within such industries as financial services, media and
entertainment, retail, healthcare, telecommunications, transportation, utilities
and service bureaus.  Davox(R) products and services are used by more than 1,000
organizations worldwide.



Davox was incorporated in Massachusetts in 1981 and reorganized in Delaware in
1982. The Company's common stock is listed on the NASDAQ National Market under
the symbol "DAVX".  The Company is headquartered in Westford, Massachusetts.
The mailing address for the Company's headquarters is 6 Technology Park Drive,
Westford, Massachusetts, 01886 and its telephone number is (978)952-0200. Davox
can also be contacted through its web site at www.davox.com.

OVERVIEW
- --------

Over the past few years, call centers have transformed into contact centers that
are designed to handle a wide range of customer interactions across a variety of
media including telephony, e-mail and web-enabled communications. These diverse
communications are unified by a common goal: establishing direct links between
contact center agents and customer information

                                       2
<PAGE>

that deliver tangible improvements in sales and satisfaction.

In pursuit of this goal, Davox acquired AnswerSoft, Inc. in May 1998. As a
developer of inbound call routing, reporting and agent desktop automation
software specifically designed for the needs of the inbound-oriented contact
center, AnswerSoft's capabilities complemented Davox's leadership in outbound
and blended call center systems. After the acquisition, Davox integrated and
modularized AnswerSoft's technology into its product offerings, thereby
transforming the company into a full-service solution provider for contact
centers.

Subsequent to this integration effort, Davox introduced its Ensemble customer
interaction management suite in December 1999.  Ensemble is a modular,
integrated solution that enables companies to optimize the value of their
customer interactions across a broad range of media. The system integrates
inbound call routing, outbound call management, seamless call blending, web
capabilities, desktop automation and comprehensive reporting capabilities.  The
product's modular design makes these capabilities fully scalable, thereby
providing a framework for the continued growth and evolution of our customers'
technology investments.

Ensemble continues Davox's 20-year tradition of industry leadership. Designed to
address the strategic needs of world-class organizations, Ensemble(TM) reflects
Davox's long-standing commitment to provide solutions that are rapidly deployed,
highly automated and capable of delivering a rapid return on our customers'
technology investments.

The introduction of Ensemble supports the Company's efforts to achieve two key
strategic objectives: (i) to increase its market share in the customer contact
industry and (ii) to establish Ensemble as the standard for customer interaction
management.

As customer interaction management functions become increasingly critical to the
success of an enterprise, customer contact solutions must demonstrate a proven
ability to assist organizations in achieving their strategic goals. Ensemble(TM)
provides the opportunity to deliver key benefits to service-oriented customer
contact centers:

 .  ENHANCED REVENUES - The consolidation of mission-critical customer
   interaction management functions enables senior managers to track complete
   customer contact performance and identify potential cross-selling
   opportunities.

 .  REDUCED OPERATING COSTS - Organizations can consolidate redundant or parallel
   systems and agent pools by integrating both inbound and outbound customer
   communications.

 .  INCREASED PRODUCTIVITY - Agents can perform a greater number of automated
   tasks and reach more customers through multiple channels.

 .  IMPROVED CUSTOMER SERVICE - Customer loyalty is enhanced because customers
   can communicate via the method that best suits their needs.

The Company believes that its Ensemble(TM) customer contact suite addresses the
needs of today's customer contact centers and is an optimal solution for
organizations looking to deliver world class service to their customers while
increasing revenues, agent productivity and gaining competitive advantage by
reducing operating costs.

PRINCIPAL PRODUCTS AND APPLICATIONS
- -----------------------------------
Davox's product strategy is focused on its three major product lines:
Ensemble(TM), Unison(R) and LYRICall(TM).

ENSEMBLE

Released in North America in December 1999, Ensemble is a modular, integrated
solution that combines inbound, outbound, and blended call management with
powerful desktop automation tools, web capabilities and sophisticated real-time
and historical reporting.  Since its release in December, Ensemble has been
recognized with two industry awards: Call Center News' Hot Picks 2000 and 1999
Product of the Year by Call Center CRM Solutions magazine

Ensemble is comprised of the following modules that can be deployed as either
stand-alone applications or as part of a set of integrated capabilities tailored
to meet specific technological and operational requirements:

 .  ENSEMBLE INBOUND - Supports inbound call processing requirements, such as
   routing calls to specific agents or Automatic Call Distributor (ACD) queues,
   converts telephony-based information into automated screen pops at the agent
   workstation; and facilitates voice/data transfers.

 .  ENSEMBLE OUTBOUND - Provides powerful predictive and preview dialing,
   campaign and call list management, scheduled recalls, automated messaging,
   real-time filtering, system alerts and voice/data transfers.

 .  ENSEMBLE BLEND - Utilizes computer telephony integration (CTI) and non-CTI
   integration to provide a seamless, blended environment that can be used to
   monitor ACD queues that reflect service thresholds.

 .  ENSEMBLE DESKTOP - Provides a link between front-line agents and back-office
   customer information systems. Based on Davox's browser-based scripting and
   agent application software, LYRICall(TM), Ensemble Desktop provides contact
   center agents with the tools necessary to execute more successful customer
   contacts.

 .  ENSEMBLE REPORTING - Provides real-time and historical reporting capabilities
   that allows managers to effectively manage their contact center operations.

Key functional highlights of the Ensemble(TM) platform include:

 .  ENTERPRISE-WIDE VOICE/DATA TRANSFER - With Ensemble(TM), data gathered during
   a particular contact moves with the call during transfers. The accumulated
   information is automatically forwarded from one contact center agent to the
   next. This capability reduces call handling times, and increases "first call"
   resolution rates without compromising customer satisfaction.

 .  INTEGRATED MANAGEMENT CONSOLE - An integrated console enables supervisors to
   manage both telephony (inbound, outbound, and blend) and email/web based
   interactions through a single workstation. The console includes a number of
   features that help improve operational effectiveness, such as an Alerts
   feature, which notifies the supervisor when defined productivity benchmarks
   run the risk of being compromised.

 .  SINGULAR CTI LINK - Ensemble(TM) transfers screen pop information from
   various sources to the contact center agent desktop via a consolidated CTI
   link. This feature leverages investments in existing resources by allowing
   Davox customers to channel all CTI-related activities through a single
   source, without relying on multiple vendors.

 .  LIFE CYCLE CALL TRACKING - Ensemble's call tracking features gather
   transaction information that can be used to identify and address the contact
   center's customer

                                       4
<PAGE>

   activity trends. These records include specialized forms of information, such
   as call segment length and enterprise-wide call movement patterns, that can
   be used to fine-tune operations and enhance customer satisfaction.

Ensemble is scheduled to be available for international shipments in the second
quarter of 2000.  Pricing for Ensemble starts at approximately $1,500 per agent.

The Company plans to increase and enhance the capabilities of the Ensemble
solution during 2000.  The next major release of the product, version 2.0, is
scheduled for distribution during the second quarter of 2000.  It is expected
that this release will incorporate a new module called Ensemble Online that will
integrate electronic mail contact management with telephone contact management.
In November 1999, Davox entered into a technology licensing agreement with Kana
Communications, a leading provider of online customer communications solutions
based in Palo Alto, California.  Under the terms of the agreement, Davox will
incorporate e-business technologies from Kana for e-mail response into version
2.0 of its Ensemble customer contact suite.

The Company believes that this new online functionality will address one of the
fastest-growing requirements in customer interaction management: the need to
provide e-mail communications that are linked with telephony-based functions.
Ensemble's automated e-mail response capability is expected to enable companies
to begin the implementation of a convergent solution that accommodates both
telephony- and Internet-based interactivity.

UNISON(R)
Introduced in 1993, the Unison(R) call management system is designed to automate
the full range of outbound and blended calling activities within the customer
contact center. It integrates with existing voice and data systems, manages
outbound and call-blending applications and provides high-productivity tools to
increase the number of calls handled and the quality of each customer contact.

Unison technology is used primarily in customer contact centers with outbound
and blended calling requirements, such as credit/collections, telemarketing,
fundraising, and customer service.  Unison is an award-winning, time-tested call
management solution that is used by companies throughout the world to meet their
mission-critical customer contact needs.

One of the key differentiating features of the Unison system is its Rules
Based(TM) Management technology. This technology enables customer contact
centers to define the parameters of calling campaigns based on specific business
objectives. The Unison system automatically implements the strategies, measures
calling effectiveness, and enables customer contact center managers to make
adjustments to calling campaigns in real-time without disrupting operations.

Unison is a fully scaleable architecture that lets contact centers modify and
extend the system without compromising system performance.

                                       5
<PAGE>

Unison is designed to provide key outbound call management functionality,
including predictive and preview dialing, campaign and call list management,
scheduled recalls, automated messaging, real-time filtering, system alerts, and
voice/data transfers.  The Unison system also provides a graphical management
console that monitors critical functions and displays information about calling
campaigns.


The Company believes that sales of Unison will remain strong as organizations
continue to seek effective solutions for outbound-based calling campaigns. As
such, the Company plans to commit resources to enhancing the product as dictated
by the marketplace.

Unison system pricing starts at approximately $100,000.


LYRICALL(TM)
Released in 1998, the Company's LYRICall software is designed to provide a link
between front-line contact center agents and back-office customer information
systems.

Utilizing Internet standard technologies, LYRICall provides customer contact
center agents with the ability to access customer specific data that empower
them to execute more successful customer contacts.  Designers can quickly create
and deploy intuitive screen and script pages that help reduce implementation
costs, maximize agent productivity and increase customer satisfaction.

LYRICall features wizard and template functions that guide designers through the
creation of customer contact scripts and applications.  Designers can create
applications using browser, Java, and HTML technologies without requiring
programming skills.  Designers can write an application once and then deploy it
across a range of industry-standard devices and operating systems, including
desktop appliances and network computers.  This significantly reduces
development costs and deployment times.  LYRICall also requires no additional
client software to be installed on agent workstations, making the LYRICall
solution a true web-enabled interface.

LYRICall has been recognized with a variety of industry awards such as Best of
Show at CT Expo and 1999 Product of the Year from CTI Magazine.

The Company believes that there will continue to be significant growth
opportunities for LYRICall in all major geographies during 2000 and beyond.  As
such, the Company is committed to providing the resources required to continue
to enhance the functionality and capabilities of this innovative product.

Pricing for LYRICall starts at $700 per agent.

MARKETS AND DISTRIBUTION CHANNELS
Davox products and services are sold worldwide through multiple distribution
channels, including a direct sales force, distributors and resellers.

NORTH AMERICAN OPERATIONS

In North America, Davox sells its products primarily through a direct sales
force.  Sales activities are organized and managed in three regions, each
consisting of territory representatives and solution consultants.  Offices are
located throughout the United States and Canada.

Davox territory sales representatives and solution consultants take a solutions-
driven approach in working with prospective customers.   Customer business goals
and integration requirements are clearly identified and defined before the sale
ensuring customer expectations are properly met on a timely basis.   This
consultative selling approach, combined with Davox's own Enterprise Solutions
resources for application development and integration, ensure that the right
solution is quickly deployed to meet customer requirements.

In addition to direct sales in North America, Davox uses authorized resellers to
provide additional market coverage and revenue contribution.  These resellers
include Siemens Information & Communication Networks, Inc. and Lucent
Technologies, Inc.  The Company plans to expand its authorized reseller program
during 2000.

INTERNATIONAL OPERATIONS

During 1999, the Company expanded its sales presence in key geographic areas of
the world, establishing subsidiaries in Germany and Singapore.  In addition, the
Company has a direct sales presence in the United Kingdom (London) and Latin
America (Mexico City).  The Company plans to continue to expand its direct sales
presence in the international marketplace.

In addition to its direct sales presence in the international marketplace, Davox
licenses its products through indirect channels, utilizing distributors and
resellers.  These indirect channel partners have the ability to not only resell
product licenses, but also have substantial skills in systems consulting and
integration to meet customer requirements.  Currently, the Company's
international distributors include Wittel Comunicacoes LTDA (Brazil), GMA
Consulting S.A. (Argentina), OLTP Voice Systems, C.A. (Venezuela), Universal
Electronics & Computers, Inc. (Taiwan), IVRS International Ltd. (Hong Kong),
Marubeni Information Systems (Japan), Lake Corporation (Australia), Affinity
Communications (f.k.a. Data DPS(s) PTE LTD.), (Singapore), DataMetrix AB
(Scandinavia), Advanced Voice Applications BV (Netherlands), Teledynamics BV
(Belgium, the Netherlands and Luxembourg), DataPoint Corporation (Europe),
Sinclair Voicenet Limited (Scotland), and Multi-Connect (pty.) Ltd. (South
Africa).

In connection with sales outside the United States, some Davox products are
subject to regulation by foreign governments, which requires the Company to
follow certain telecommunications and safety certification procedures for some
countries.  Failure to obtain necessary local country approvals or
certifications will restrict Davox's ability to sell into some countries.  In
addition, other factors including, but not limited to currency rate fluctuation,
import/export restrictions, political instabilities and other unknown or
unforeseen eventualities, may affect international sales.

                                       7
<PAGE>

International product revenue was approximately $10.8 million, $9.7 million and
$14.7 million, or approximately 20%, 18% and 25% of product revenue in 1999,
1998, and 1997, respectively.

In 1999, the Company derived 80% of its product revenue from North America; 16%
from Europe, the Middle East, and Africa; 3% from Asia Pacific; and 1% from
Latin America.

SUPPORT SERVICES
The Company offers a full line of warranty, service and support options in all
of its geographic markets. Central to the Company's maintenance service
offerings is the Worldwide Support Center located at Davox headquarters in
Westford, Massachusetts.  The Company also operates satellite support offices in
Slough, United Kingdom, and Mexico City.  From these locations, Davox support
professionals accept and manage telephone, web and email requests from customers
for information and remedial support.  Using state-of-the-art case management
and diagnostic tools, the support centers provide end-to-end problem resolution.

Davox's contract coverage includes access to Davox's support web site for case
logging, interactive problem resolution, periodic maintenance updates and 24
hour x 365 day priority phone support, problem escalation and on-site hardware
maintenance requests.

The Company offers a tiered support program for its distributor channel.
Included in the program are periodic maintenance updates to distributors'
enrolled end-user base, access to Davox's distributor web site, escalated
support for distributor personnel, recommended training curriculums and a spare
parts repair/exchange program.

Davox seeks out and contracts hardware support with independent third party
service providers who are recognized for quality support and customer care
practices.  Currently, these services are provided by Grumman Systems Support
Corporation ("GSSC"), a wholly owned subsidiary of Northrop Grumman Corporation
in the United States and Canada.

In addition, GSSC provides network design and systems integration services
allowing Davox to focus its expertise on customizing advanced contact center
solutions for its customers. Similar services are provided in the United Kingdom
by G&A Business Solutions, Ltd., and in Mexico by TECOcibernetica.  The Company
believes that it has adequate resources internally and externally in order to
provide services to its customers and partners in the event services from these
organizations should cease in any manner, however loss of any one of these
relationships could materially adversely affect the ability for Davox to provide
support to its customers and partners in the geographic region covered by such
organization.

In early 1994, Davox discontinued its Computerized Automated Dialing System
(CAS(R)) and Communications Resource Server(R)/controller workstation (CRS(R))
products from its product line. Each of these products has now matured to the
end of its "useful life." Accordingly, Davox notified its CAS and CRS customers
in writing that the Company will no longer offer maintenance and support
services for these products after December 31, 1999.

                                       8
<PAGE>

Davox's Educational Services offers a variety of courses designed to provide
customer contact centers with the skills and knowledge needed to enhance
productivity and raise the level of service they deliver to their customers.
Davox training facilities are located in Acton, Massachusetts; Richardson,
Texas; and Slough, United Kingdom.  The Company also offers customized courses
at customer locations.

The Company's Professional Services group was established in 1997 and
reorganized in January 2000 as an Enterprise Solutions Services group.  This
organization was established to expand the consulting and integration services
Davox offers to its customers.  Drawing on the wealth of experience within
Davox, the organization offers consulting expertise on agent desktop automation,
database integration, call flow automation, project management and other
services to help customer contact centers enhance the productivity and value of
their Davox systems. These services focus on both the traditional customer
contact center as well as the emerging e-business markets.

Service revenue accounted for $38.6 million, or 42% of the Company's total
revenue in 1999.  This is an increase of $3.5 million from $35.1 million or 39%
of the Company's total revenue in 1998.  The Company's service revenue for 1998
increased $9.8 million from $25.3 million or 30% of the Company's total revenue
in 1997.

OPERATIONS

While the majority of the Company's hardware needs are met by readily available
off-the-shelf technology, a small portion remains proprietary. Third-party
contractors manufacture these proprietary hardware components and the Company
believes there are many qualified vendors for these services. The Company's
production process consists primarily of product staging, quality assurance,
final test and systems integration which occurs at its Westford facility.

The Company attempts to maintain multiple sources of supply for key items and
believes it has adequate sources of supply for its expected needs.  While any of
these sources could be replaced if necessary, the Company might face significant
delays in establishing replacement sources or in modifying its products to
incorporate replacement components or software code. There can be no assurance
that the Company will not suffer delays resulting from non-performance by its
vendors or cost increases due to a variety of factors, including component
shortages or changes in laws or tariffs applicable to items imported by the
Company.

STRATEGIC PARTNERSHIPS

A complete customer relationship management system is extremely complex and
always entails integration with existing telecommunications systems, databases
and front office applications to fully meet customer requirements.  Currently,
no vendor provides all the requisite elements for a fully integrated customer
relationship management system.

To meet this challenge and to increase its market opportunity, Davox has
undertaken strategic partnerships with various complementary technology and
platform vendors.  These partners include Sun Microsystems, Kana Communications,
Siebel Systems, IEX Corporation, CenterForce Technologies, Witness Systems and
Microsoft.

                                       9
<PAGE>

Additionally in 1999, Davox and Kana Communications entered into a global
reseller and technology licensing agreement, whereby Davox secured rights to
resell Kana's industry-leading online customer communications products.  In
addition, Davox expects to integrate selected Kana technology into the next
major release of its Ensemble customer contact suite scheduled for release in
the second quarter of 2000.

COMPETITION
Davox currently competes in two distinct markets: customer interaction
management and outbound call management.

In the customer interaction management market, Davox offers its Ensemble product
suite which includes inbound, outbound, and blended call management as well as
online customer contact functionality that is essential in implementing an
overall customer relationship management system.

According to industry market analysts Datamonitor, the customer interaction
management market segment is expected to grow to more than $3 billion worldwide
by 2003 and is considered the second fastest software growth segment (28% CAGR,
1998 to 2003).

In this market, the Company currently competes with, among others, Genesys
Telecommunications (being acquired by Alcatel), Cisco System's Intelligent
Contact Management product line (comprised of recent acquisitions of Geotel and
Webline), Aspect Communications and Quintus Corporation.

In the outbound call management marketplace, Davox offers its Unison system.
Unison is an industry leading outbound solution for managing outbound and
blended calling campaigns primarily within telemarketing and collections
organizations.

According to industry market analysts Datamonitor, this market is projected to
grow to $730 million worldwide by 2003 (13% CAGR, 1998-2003).  Much of this
growth opportunity exists in markets outside of North America.

In this market, the Company currently competes with, among others, eShare
(formerly Melita), EIS International and Lucent Technologies' call center
solutions unit, which includes the recent acquisition of Mosaix.

The Company believes that it has a number of advantages over its competitors in
the areas of product functionality, integration, deployment time and customer
service.

Certain of the Company's current and potential competitors are larger companies
that have greater financial, technical and marketing resources.  It is possible
that competitors could produce products that perform the same or similar
functions as those performed by the Company's products. In addition, current and
potential competitors have established and may in the future establish
cooperative relationships among themselves or with third parties to increase the
ability of their products to address the needs of the Company's current or
prospective customers.  Accordingly, it is likely that new competitors or
alliances among such competitors will emerge and may rapidly acquire significant
market share, which would have a material adverse effect on the Company's
business, financial condition and results of operations.  In order to be
successful in the future, the Company must respond promptly and effectively to
the challenges of technological change, changing customer requirements and
competitive pressures.

                                       10
<PAGE>

Increased competition could make it more difficult for the Company to maintain
its market presence.

SIGNIFICANT CUSTOMERS

Davox has more than 1,000 customers that are located worldwide and represent a
cross section of industries.  For the year ended December 31, 1999, AT&T was the
Company's largest single customer, accounting for approximately 12% of total
revenue.  In 1998, Lucent Technologies, Inc., a distributor of Davox products,
was the Company's single largest customer, accounting for approximately 13% of
total revenue.  In 1997, Datapoint Corporation, a distributor of Davox products,
was the largest single customer, accounting for approximately 10% of total
revenue.  Total revenue from the Company's top three customers amounted to
approximately 24%, 24% and 18% of total revenue in 1999, 1998 and 1997,
respectively. The Company believes that its dependence on any end user customer
or reseller is not likely to increase significantly as its products continue to
be accepted by both existing customers and new accounts in major industries
worldwide.

MARKETING AND PROMOTION

During 1999, Davox increased its investment in worldwide marketing and promotion
to increase awareness and demand for its products.  Marketing activities include
targeted print advertising, web-based marketing, seminars, trade shows and
press/analyst relations.   Davox also established joint marketing relationships
with a number of key technology alliance and distribution partners worldwide,

RESEARCH, DEVELOPMENT AND ENGINEERING

The Company's product development efforts are aimed at designing and developing
customer contact center software that meets software industry standards and
incorporates technologies and features that the Company believes its customers
require.  Most of the Company's products are developed internally by research
and development teams located at the Company's headquarters in Westford,
Massachusetts, and at a satellite development facility located in Richardson,
Texas.  The Company also licenses certain technology and intellectual property
rights from third parties. The Company believes that by establishing mutually
beneficial relationships with third party technology companies it can provide
its customers with emerging technologies in the most timely and cost-effective
manner.

The Company also believes that a critical success factor of a new product is
getting it to market quickly. During 1999, Davox undertook a variety of
initiatives to accelerate the delivery of products to the marketplace.  A
program management function was added to the Company's product introduction
process.  This group is responsible for managing the introduction of new and
enhanced products across various functions at Davox.  The Company believes that
the establishment of this key group will help to ensure corporate readiness to
ship and support products at an accelerated pace.  The Company's Quality
Assurance Group was also expanded to provide enhanced quality testing across all
products.  Finally, the Company has entered into a key technology agreement with
Kana Communications in order to incorporate Internet-related technologies into
its product line.

The Company's continued success depends on, among other factors, maintaining
close working

                                       11
<PAGE>

relationships with its customers, business partners and resellers
and anticipating and responding to their evolving applications needs. The
Company is committed to the development of new products, the improvement of
existing products, and the continued evaluation of new technologies.

The Company spent $13.3 million on research and development in 1999, compared
with $12.1 million in 1998 and $10.4 million in 1997.  This represented
approximately 14%, 14%, and 12%, respectively, of total revenue in each of those
years.  The Company expects to incur approximately the same level of development
costs during 2000.

In addition, the Company did not capitalize any of its software development
costs in 1999, 1998 or 1997, as the additional development costs incurred to
bring the Company's products to a commercially acceptable level after
technological feasibility has been established are not significant.

INTELLECTUAL PROPERTY

The Company relies on a combination of patent, copyright, trademark, contract
and trade secret laws to establish and protect its proprietary rights in its
technology.  The Company owns and licenses a number of patents relating to
predictive dialing, real-time telecommunication management, client/server
computer telephony software, and user interfaces.  Software products are
furnished under software license agreements that grant customers licenses to
use, rather than to own, the products. The license agreements contain provisions
protecting the Company's ownership of the underlying technology.  Upon
commencement of employment, employees execute a non-disclosure and invention
agreement under which inventions developed during the course of employment will,
at the election of the Company, be assigned to the Company and which further
prohibits disclosure of confidential Company information. There can be no
assurances that the steps taken by the Company in this regard will be adequate
to prevent misappropriation or infringement of its technology or that Davox's
competitors will not independently develop technologies that are substantially
equivalent or superior to Davox's technology. See also "Item 3-Legal
Proceedings." Effective protection of intellectual property rights may be
limited or unavailable in certain foreign countries.

EMPLOYEES

As of December 31, 1999, the Company had 444 employees worldwide, of whom 28
were engaged in operations; 292 in sales, marketing and customer support; 78 in
research, development and engineering; and 46 in administrative functions.  None
of the Company's employees is represented by a collective bargaining agreement,
nor has the Company ever experienced any work stoppage.  The Company considers
its relations with its employees to be good.

CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

From time to time, information provided by the Company, statements made by its
employees or information included in its filings with the Securities and
Exchange Commission (including this Form 10-K) may contain statements which are
not historical facts, so-called "forward-looking statements".  Such forward-
looking statements involve risks and uncertainties which may adversely impact
whether or not such forward-looking statements come true.  In particular, but
without limitation, statements, implied or actual, in "Item 1. Business",
relating to: (i) the Company's objective to gain market share and make Ensemble
the standard for customer contact management and the fact that Ensemble
addresses the needs of today's customer contact center; (ii) the international
availability of Ensemble being in the second quarter of 2000; (iii)

                                       12
<PAGE>

releasing Ensemble Online in version 2 of Ensemble and its associated beneficial
synergies; (iv) the prediction that Unison sales will remain strong as
organizations continue to seek effective solutions for outbound-based calling
campaigns and that the Company will continue to commit resources to enhancing
Unison; (v) the plan to expand the Company's authorized reseller program; (vi)
the plan to expand the direct sales presence internationally; (vii) the
potential benefits as a result of the growth in the customer interaction
management market segment; (viii) the potential benefits as a result of the
growth in the outbound call management market; (ix) the prediction that the
Company's dependence on any one customer should not increase; (x) the fact that
the Company licenses (and plans to continue licensing) technology from other
parties, may be forward-looking statements. The Company's actual future results
may differ significantly from those stated in any forward-looking statements.
Factors that may cause such differences include, but are not limited to, the
factors discussed below. Each of these factors, and others, are discussed from
time to time in the Company's filings with the Securities and Exchange
Commission.

The Company's future results may be subject to substantial risks and
uncertainties.  The Company purchases certain equipment for its products from
third-party suppliers and licenses certain components of its software code from
a number of third-party vendors.  While the Company believes that third-party
equipment and software vendors could be replaced if necessary, the Company might
face significant delays in establishing replacement sources or in modifying its
products to incorporate replacement components or software code.  There can be
no assurance that the Company will not suffer delays resulting from non-
performance by its vendors or cost increases due to a variety of factors,
including component shortages.  The Company uses third party service providers
to fulfill its hardware support obligations with its customers. Additionally,
the Company relies on co-providers to assist its Professional Services
organization. While the Company believes that its currently contracted service
providers and co-providers are adequate at this time, the Company may face
significant delays in establishing replacement providers for such services.

The Company relies on certain intellectual property protections to preserve its
intellectual property rights.  Any invalidation of the Company's intellectual
property rights or lengthy and expensive defense of those rights could have a
material adverse affect on the financial position and results of operations of
the Company.

The development of new products, the improvement of existing products and the
continuing evaluation of new technologies is critical to the Company's success.
Successful product development and introduction depends upon a number of
factors, including anticipating and responding to the evolving applications
needs of customers and resellers, timely completion and introduction of new
products, and market acceptance of the Company's products.

The customer interaction management and outbound call management industries are
extremely competitive. Certain current and potential competitors of the Company
are more established, benefit from greater market recognition and have
substantially greater financial, development and marketing resources than the
Company.

Additionally, the Company's quarterly and annual financial and operating results
are affected by a wide variety of factors that could materially adversely affect
revenue and profitability, including: the timing of customer orders; the
Company's ability to introduce new products on a timely basis; introduction of
products and technologies by the Company's competitors; and market acceptance of
the Company's and its competitors' products; effects of litigation

                                       13
<PAGE>

described in Item 3 Legal Proceedings; the ability to hire and retain key
personnel and difficulties of any nature as a result of the impact of the Year
2000 on Davox, its customers, its vendors or its distributors.

International sales are expected to continue to account for a significant
portion of the Company's net sales in future periods.  International sales are
subject to certain inherent risks, including, but not limited to those risks
discussed in this section and elsewhere in the Form 10-K, unexpected changes in
regulatory requirements and tariffs, difficulties in staffing and managing
foreign operations, longer payment cycles, problems in collecting accounts
receivable, potentially adverse tax treatment, and the inability to expand
distribution channels.  As a result of the foregoing and other factors, the
Company may experience material fluctuations in future financial and operating
results on a quarterly or annual basis, which could materially and adversely
affect its business, financial condition, results of operations and stock price.

ITEM 2. PROPERTIES
- ------------------

The Company's corporate offices are located at a 60,000 square foot, two-story
building in Westford, Massachusetts.  The facility is occupied under a lease
that expires in September 2008.  The Company also leases a Richardson, Texas
facility of approximately 26,000 square feet, which expires in January 2002.  In
addition, the Company leases facilities for district and regional sales and
service offices in seven states as well as in Canada, the United Kingdom,
Mexico, Singapore and Germany. The current aggregate annual rental payments for
all of the Company's facilities are approximately $2.0 million.

In January 2000, the Company signed an amended lease under which it will add a
25,000 square foot addition to its Westford, Massachusetts facility.  The
Company expects that the addition will be ready for occupancy by the end of
2000.

ITEM 3. LEGAL PROCEEDINGS
- --------------------------

In 1998, a customer of Davox was sued for patent infringement by Manufacturing
Administration and Management Systems, Inc. (MAMS) alleging that the customer's
use of a computer driven automated dialer infringes MAMS's patent. Under Davox's
contract with this customer, Davox is obligated to defend and indemnify such
customer against any such claims. In the third quarter of 1998, Davox sued MAMS
in federal court in the Eastern District of New York in an action entitled
"Davox Corporation v. Manufacturing Administration and Management Systems, Inc."
In the lawsuit, Davox is seeking a declaratory judgment that its products do not
infringe the MAMS patent or, in the alternative, that the MAMS patent is
invalid. Davox believes that MAMS's assertions of patent infringement are
without merit, and Davox will vigorously pursue this action against MAMS. While
the outcome of this litigation cannot be predicted with certainty at this time,
management does not believe that the outcome will have a material adverse effect
on the Company's business, financial condition or results of operations.

                                       14
<PAGE>

The Company is from time to time subject to claims arising in the ordinary
course of business.  While the outcome of the claims cannot be predicted with
certainty, management does not expect these matters to have a material adverse
effect on the results of operations and financial condition of the Company.

such times when the Company deems such purchases to be an effective use of cash.
Shares that are repurchased may be used for various purposes including the
issuance of shares pursuant to the Company's stock option plans. Under the
stock repurchase program, shares may be repurchased, at management's discretion,
from time to time at prevailing prices in the open market. The repurchase
program of three million shares represented approximately 21% of the Company's
issued and outstanding shares at that time. As of February 29, 2000, the Company
had repurchased 1,326,400 shares under this repurchase program.

</TABLE>


   Total revenue was approximately $92.4 million, $88.9 million and $83.6
million for the fiscal years ended December 31, 1999, 1998 and 1997,
respectively.  Total revenue increased

                                       21
<PAGE>

4.0% for the year ended December 31, 1999 compared to the same period in 1998
and increased 6.5% in fiscal year 1998 compared to fiscal year 1997. Total cost
of revenue as a percentage of total revenue was 33.3% in fiscal year 1999, 33.8%
in fiscal year 1998 and 33.5% in fiscal year 1997.

   Product revenue was approximately $53.8 million, $53.8 million and $58.3
million in fiscal years 1999, 1998 and 1997, respectively.  Product revenue was
consistent in 1999 and decreased by 7.7% in 1998 as compared to 1997. The
decrease in 1998 was due to lower product sales in the international market,
which was only partially offset by a slight increase in domestic sales.

   Cost of product revenue as a percentage of product revenue was 18.2%, 19.5%,
and 20.7% in fiscal years 1999, 1998 and 1997, respectively.  The decrease as a
percentage of product revenue in 1999 and 1998 was due to the continued decrease
in the hardware content of the Company's products.

   Service revenue was approximately $38.6 million, $35.1 million, and $25.3
million in fiscal years 1999, 1998 and 1997, respectively.  Service revenue
increased 9.9% and 39.1% in 1999 and 1998, respectively. The increase in 1999
was due to increased professional services revenue and an increase in
maintenance revenue related to the growth in the installed base of the Company's
products in recent years.  The increase in 1998 was due to an increase in
maintenance revenue related to the growth in the installed base of the Company's
products and increased implementation and professional services revenue over
1997.

   Cost of service revenue as a percentage of service revenue was 54.2%, 55.8%
and 63.3% in 1999, 1998 and 1997, respectively.  These decreases as a percentage
of service revenue were attributable to the growth in service revenue in 1999
and 1998, which exceeded the associated increases in the costs of servicing a
larger installed base of products.

   Revenue from the Company's largest single customer in each of 1999, 1998 and
1997 was approximately 12%, 13%, and 10% of total revenue, respectively.
Revenue from the Company's three largest customers amounted to 24%, 24% and 18%
of total revenue in 1999, 1998 and 1997, respectively.  The Company intends to
continue to broaden its base of existing and new customers by penetrating new
markets, expanding its direct international sales force and using alternate
channels of distribution, thereby decreasing its dependence on its largest end-
user customers.

   Research, development and engineering expenses were approximately $13.3
million, $12.1 million and $10.4 million, representing 14.4%, 13.6% and 12.5% of
total revenue during 1999, 1998 and 1997, respectively.  The increase in 1999
was primarily attributable to higher payroll, depreciation and consulting
expenses compared to 1998.  The increase in 1998 was due to higher payroll
expenses compared to 1997.

   Selling, general and administrative expenses were approximately $37.1
million, $34.8 million and $29.7 million, representing 40.1%, 39.2% and 35.6% of
total revenue during 1999, 1998 and 1997, respectively. The increases in 1999
were mostly attributable to increased bonus and commission expense and increased
payroll and related expenses.  The increases in 1998 were primarily attributable
to increased payroll and related expenses, increased travel and related sales
expenses, and increased consulting fees.

                                       22
<PAGE>

   For the year ended December 31, 1998, in connection with the merger with
AnswerSoft, Inc., the Company incurred non-recurring merger transaction costs,
primarily professional fees, of $1.3 million. In addition, the Company incurred
non-recurring costs, primarily severance and lease termination costs, of
$597,000 related to the integration of the two businesses.

   Other income, derived primarily from investments in commercial paper,
corporate bonds, Eurodollar bonds, and money market instruments decreased 4.3%
in 1999 and increased 44.8% in 1998.  The decrease in 1999 was due to lower
average cash balances as the Company repurchased approximately 1.3 million
shares of its common stock at an aggregate cost of $10.2 million during 1999.
The increase in 1998 was due primarily to the significant increase in the
average cash and cash equivalent and marketable securities balances over the
prior fiscal year.

INCOME TAXES

   The Company provided for income taxes at estimated annual effective tax rates
of 15.0%, 34.0% and 14.4% for 1999, 1998 and 1997, respectively.  These rates
are lower than the combined federal and state statutory tax rates due primarily
to the utilization of net operating loss and tax credit carryforwards and
benefits derived from the Company's foreign sales corporation. The Company's
1999 effective tax rate reflects the utilization of net operating losses
resulting from the Company's acquisition of AnswerSoft, Inc. in 1998.

LIQUIDITY AND CAPITAL RESOURCES

   As of December 31, 1999, the Company's principal sources of liquidity were
its cash and cash equivalent balances of approximately $34.4 million, and its
marketable securities of approximately $30.8 million.  As of December 31, 1998,
the Company's principal sources of liquidity were its cash and cash equivalent
balances of approximately $31.8 million, and its marketable securities of
approximately $27.7 million. The overall increase in cash and cash equivalents
and marketable securities was due primarily to favorable operating results and
proceeds from exercises of stock options. In addition, the Company has an
agreement for a working capital line of credit with a bank for up to $2.0
million based on eligible receivables, as defined.  There were no outstanding
balances as of December 31, 1999 or 1998 under this line of credit.

   The Company's primary investing activities were purchases of property and
equipment, and purchases and sales of marketable securities.  Property and
equipment purchases were approximately $3.4 million in 1999 compared to
approximately $3.4 million and $4.6 million in 1998 and 1997, respectively.
Purchases and sales of marketable securities generated a net cash outflow of
approximately $3.1 million in 1999 compared to a net cash outflow of
approximately $3.9 million and $14.0 million in 1998 and 1997, respectively.

   Cash used by financing activities in 1999 was $8.8 million and resulted from
the Company's repurchase of approximately 1.3 million shares of its common stock
at an aggregate cost of $10.2 million, partially offset by proceeds generated
from the exercise of stock options and shares purchased by employees under the
Company's employee stock purchase plan.  Cash provided by financing activities
in 1998 was approximately $1.9 million, which was generated primarily from
proceeds from exercises of stock options and shares purchased by employees under
the Company's employee stock purchase plan.  Cash provided by financing
activities in 1997 was approximately $7.7 million, and was generated primarily
from the issuance of $5.1

                                       23
<PAGE>

million of AnswerSoft preferred stock and from proceeds from the exercise of
stock options and shares purchased by employees under the Company's employee
stock purchase plan.

   Working capital as of December 31, 1999 was approximately $66.1 million as
compared to approximately $62.8 million as of December 31, 1998.  Total assets
as of December 31, 1999 were approximately $99.0 million compared to
approximately $89.4 million as of December 31, 1998.  These increases were
primarily attributable to increases in cash and cash equivalents, marketable
securities and accounts receivable due to the Company's favorable operating
results.

   Management believes, based on its current operating plan, that the Company's
existing cash and cash equivalents, marketable securities, cash generated from
operations and amounts available under its working capital line of credit will
be sufficient to meet the Company's cash requirements for the next twelve
months.

IMPACT OF INFLATION

   The Company believes that inflation did not have a material effect on the
results of operations in 1999, 1998 and 1997.

NEW ACCOUNTING STANDARDS

     In June 1999, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 137, Accounting for Derivative
Financial Instruments and Hedging Activities - Deferral of the Effective Date of
FASB Statement No. 133, which defers the effective date of SFAS No. 133 to all
fiscal quarters of all fiscal years beginning after June 15, 2000.  SFAS No.
133, Accounting for Derivative Instruments and Hedging Activities, establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts, and for hedging activities.
It requires entities to recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value.  The Company does not anticipate the adoption of these Statements
to have a material impact on its financial position or results of operations.

YEAR 2000 READINESS DISCLOSURE - made pursuant to the Year 2000 Information and
Readiness Disclosure Act, Pub. L. No. 105-271 (1998)

     The Year 2000 presented potential concerns and issues for the Company as
well as other companies in the information technology industry. In general, Year
2000 readiness issues typically arose in computer software and hardware systems
that use two digit date formats, instead of four digit dates, to represent a
particular year.  Users had to test their unique combination of hardware, system
software (including databases, transaction processors, and operating systems)
and application software in order to achieve Year 2000 readiness.

YEAR 2000 COMMITTEE

     The Company established a Year 2000 steering committee under the auspices
of the Company's senior technical executive to evaluate, plan and implement
policies and practices, including contingency planning, and to address the
impact of the Year 2000 on the Company

                                       24
<PAGE>

and its products. The Company's Year 2000 readiness preparations fell into three
categories: (1) product readiness, addressing product functionality; (2)
internal readiness, addressing the Year 2000 operability of internal information
technology ("IT") systems and mission critical non-IT systems; and (3) third
party readiness, addressing the preparedness of relevant third parties and the
Year 2000 operability of products furnished for internal use and resale. After
reviewing these areas, the committee reported to the Board of Directors specific
areas of concern and a plan for resolving and further testing of any remaining
Year 2000 issues. The committee also formulated a contingency plan in the event
that the committee reasonably determined that certain Year 2000 issues may not
be resolved by the end of 1999 or if unforeseen problems arose. As of the date
of this filing, the Company has not encountered any material problems. Despite
this fact, the Company and the steering committee remain focused on addressing
any problems that may arise. The Company does not anticipate any material
problems. Should any problems arise, the Company believes it has adequate
resources to address them properly.

PRODUCT READINESS

     The Company established Year 2000 date operability standards against which
the most current versions of its software products were tested.  The Company
completed testing of its current line of Unison(R) software products and
determined that the most current versions conform to these standards and were
Year 2000 ready. In connection with the acquisition of AnswerSoft, Inc. in May
1998, the Company acquired the Concerto(TM) line of software tool products. The
Company completed testing of the current releases of Concerto(TM) software
products and determined that they were Year 2000 ready, except IIR. All versions
of IIR were not believed to be Year 2000 ready. All customers were notified to
upgrade to SmartRouteO, which was Year 2000 ready. Despite the Company's testing
and despite the pausing of December 31, 1999, there can be no assurance that the
Company's products do not contain undetected errors or defects related to Year
2000 operability that may result in material costs to the Company or that the
Company's products contain all features and functionality considered necessary
by customers, end users and distributors to be Year 2000 ready.

   In early 1994, the Company discontinued its Computerized Automated Dialing
System ("CAS") and Communications Resource Server ("CRS") product lines and
introduced the Unison brand line of software products.  Support of the CAS and
CRS products were discontinued as of December 31, 1999.  The Company did not
test the CAS and CRS product lines and believes that they do not conform to its
test standards and were not Year 2000 ready.  The Company notified known users
of these products that support was being discontinued and that users may
experience Year 2000 related operability issues.  Users of these discontinued or
"legacy" products were encouraged to migrate to the Unison product line.  The
Company's exposure arising from its legacy products is not known. The Company
does expect to incur additional costs associated with migrating users of legacy
products, but does not believe these costs will be material.

     While the Company believes that most of its current releases of products
are Year 2000 ready, other factors may result in an application created using
the Company's products not being Year 2000 ready.  Some of these factors include
improper programming techniques used by third parties in creating the
application, customization, or non-compliance of hardware, software or firmware
not provided by the Company with which the products operate.  The Company does
not believe that it would be liable in such an event. However, due to the
unprecedented nature of the potential litigation related to Year 2000 readiness
as discussed in

                                       25
<PAGE>

the industry and popular press, the most likely worst case scenario is that the
Company would be subject to litigation. It is uncertain whether or to what
extent the Company may be affected by such litigation.

     The Company tested only the current versions of its products and did not
test earlier versions of its products.  The Company believes some of its
customers may be running product versions which have not been tested and may
experience Year 2000 date related operability issues.  The Company identified
these customers and encouraged them to migrate to current versions of the
products. Further, the Company cautioned users of such products to conduct their
own Year 2000 operability testing to determine if continued use of the products
allowed them to meet their own Year 2000 readiness objectives.  While many
customers were upgraded to Year 2000 ready versions of products under
maintenance coverage, if eligible, in the normal course the Company expects to
incur some increased expenses associated with the furnishing of upgrades and
modifications.  At this time, the Company does not believe that the cost of
potential upgrades or modifications will have a material effect on the Company's
business, financial condition and operating results.  To date, the Company has
not experienced any material adverse effects due to the Year 2000 readiness of
the most recent version of its products.

INTERNAL READINESS

     The Company conducted a Year 2000 readiness audit of its internal IT
systems (including telecommunication, facilities management, safety and security
systems).  The Company did not encounter any material operational issues or
incurring material costs associated with preparing its internal IT and non-IT
systems for the Year 2000, the Company will continue to monitor its systems and
there can be no assurance that the Company will not experience unanticipated
negative consequences or material costs caused by undetected errors or defects
in the technology used in its internal systems, which include third party
hardware, firmware, and software. To date, the Company has not experienced any
material adverse effects on its internal systems due to Year 2000 readiness.

THIRD PARTY READINESS

     The Company assessed the Year 2000 readiness of its material third parties,
such as public utilities and key clients and suppliers, who provide external
services to the Company. The Company has certain key relationships with
suppliers which furnish components and software used by the Company in its
products.  If these suppliers fail to adequately address the Year 2000 issue for
the products they supply the Company, this could have a material adverse effect
on the Company's operations, reputation, and financial results.  Certain of the
Company's products contain third party components and software that is integral
to its operation for which the cost and time to integrate alternative components
or software into these products would be material.  To date, the Company has not
experienced any material adverse effects on its business due the Year 2000
readiness of its material third parties.

CONTINGENCY PLANS AND WORST CASE SCENARIO

   The Company developed contingency plans to operate in the event that its
products, systems, or business partners were not Year 2000 ready.  The Company
did not experience any material adverse effects on its business due to the Year
2000 readiness of its products, systems or business partners.

COSTS, SOURCE OF FUNDS AND ACCOUNTING TREATMENT

   The Company expensed all costs related to its Year 2000 compliance program
unless the useful life of the technological asset was extended or increased.
The expenses incurred to date have not had a material impact on the Company's
results of operations or financial condition.  The Company funded its Year 2000
expenses through cash flows from operations. The impact of the Year 2000 was and
remains difficult to discern, but it is not considered to be a material risk
when evaluating future growth and performance of the Company.

ITEM 7(A).    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
- ----------    ----------------------------------------------------------


Derivative Financial Instruments, Other Financial Instruments, and Derivative
Commodity Instruments.

   As of December 31, 1999 and 1998, the Company did not participate in any
derivative financial instruments or other financial and commodity instruments
for which fair value disclosure would be required under SFAS No. 107.  All of
the Company's investments are short-term, Euro dollar bonds, investment-grade
commercial paper, and money market accounts that are carried on the Company's
books at amortized cost, which approximates fair market value.  Accordingly, the
Company has no quantitative information concerning the market risk of
participating in such investments.

PRIMARY MARKET RISK EXPOSURES

   The Company's primary market risk exposures are in the areas of interest rate
risk and foreign currency exchange rate risk.  The Company's investment
portfolio of cash equivalent and short-term investments is subject to interest
rate fluctuations, but the Company believes this risk is immaterial due to the
short-term nature of these investments.

   The Company's exposure to currency exchange rate fluctuations has been and is
expected to continue to be modest due to the fact that the operations of its
international subsidiaries are almost exclusively conducted in their respective
local currencies.  International subsidiary operating results are translated
into U.S. dollars and consolidated for reporting purposes.  The impact of
currency exchange rate movements on inter-company transactions was immaterial
for the years ended December 31, 1999, 1998 and 1997.  Currently the Company
does not engage in foreign currency hedging activities.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To Davox Corporation:

   We have audited the accompanying consolidated balance sheets of Davox
Corporation (a Delaware corporation) and subsidiaries as of December 31, 1999
and 1998 and the related consolidated statements of income, stockholders' equity
and cash flows for each of the three years in the period ended December 31,
1999.  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 did not audit the financial statements of
AnswerSoft, Inc., a company acquired during 1998 in a transaction accounted for
as a pooling of interests, as discussed in Note 2.  Such statements are included
in the consolidated financial statements of Davox Corporation and reflect total
revenues of $6,738,000 for the year ended December 31, 1997 of the related
consolidated totals.  These statements were audited by other auditors whose
report has been furnished to us.  Our opinion expressed herein, insofar as it
relates to amounts included for AnswerSoft, Inc., is based solely upon the
report of the other auditors.

   We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits and the report of the other auditors provide a
reasonable basis for our opinion.

   In our opinion, based on our audit and the report of the other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of Davox Corporation and subsidiaries
as of December 31, 1999 and 1998 and the results of their operations and their
cash flows for each of the three years in the period ended December 31, 1999 in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                               DECEMBER 31, 1999
              (Amounts In Thousands, Except Per Share Information)


(1)  Operations and Significant Accounting Policies

   Davox Corporation (the Company) is a software and systems integration company
that develops, markets, implements, supports and services intelligent management
systems for customer contact centers located throughout the world.  These
systems are marketed directly, through joint marketing relationships and
distribution agreements.  The Company markets its systems to banks, consumer
finance organizations, retailers, entertainment companies, telemarketing
organizations, telecommunications and transportation companies and utilities.

   These consolidated financial statements reflect the application of certain
significant accounting policies as described below and elsewhere in the
accompanying consolidated financial statements.

     (a)  Principles of Consolidation

   The accompanying consolidated financial statements include the accounts of
the Company and its wholly owned subsidiaries.  All significant intercompany
balances and transactions have been eliminated in consolidation.

     (b)  Management 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 revenue and expenses during the reporting period.
Actual results could differ from those estimates.

     (c)  Revenue Recognition

   The Company generates software revenue from licensing the rights to use its
software products.  The Company also generates service revenues from the sale of
product maintenance contracts, installation services and consulting services.
The Company recognizes revenue in accordance with the provisions of the American
Institute of Certified Public Accountants Statement of Position (SOP) No. 97-2
Software Revenue Recognition.  Revenue from software license fees are generally
recognized upon delivery, net of estimated returns, provided that there are no
significant post delivery obligations, payment is due within one year and
collection is probable.  If acceptance is required beyond the Company's standard
published specifications, software license revenue is recognized upon customer
acceptance.  SOP No. 97-2 generally requires revenue earned on software
arrangements involving multiple elements to be allocated to each element based
on the relative fair values of the elements.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                               DECEMBER 31, 1999

                                  (Continued)
             (Amounts In Thousands, Except Per Share Information)


(1)  Operations and Significant Accounting Policies (continued)

     (c) Revenue Recognition (continued)

The fair value of an element must be based on evidence that is specific to the
vendor.  If a vendor does not have evidence of the fair value for all the
elements in a multiple-element arrangement, all revenue from the arrangement is
deferred until such evidence exists or until all elements are delivered.

     Revenues for consulting services are recognized over the period in which
services are provided, the revenue is fixed and determinable and collection is
probable.  Maintenance revenue is deferred at the time of software license
shipment and is recognized ratably over the term of the support period, which is
typically one year.

     (d)  Warranty Costs

     The Company warrants its products for 90 days and defers a portion of its
revenue related to the free-warranty period, in accordance with SOP No. 97-2.

     (e)  Post-retirement Benefits

     The Company has no pension plan or other obligations for post retirement
benefits.

     (f) Cash, Cash Equivalents and Marketable Securities

     The Company considers all highly liquid investments with original
maturities of three months or less at the time of purchase to be cash
equivalents.  Cash equivalents consist mainly of commercial paper.

     The Company accounts for investments in accordance with Statement of
Financial Accounting Standard (SFAS) No. 115, Accounting for Certain Investments
in Debt and Equity Securities.  Under SFAS No. 115, securities that the Company
has the positive intent and ability to hold to maturity are reported at
amortized cost and are classified as held-to-maturity. The Company's investments
consist of held-to-maturity securities that are investments in Euro dollar bonds
and high-grade commercial paper instruments at December 31, 1999 and 1998.  All
of these investments are classified as current as they mature within one year.

(1)  Operations and Significant Accounting Policies (continued)

     (h) Research and Development and Software Development Costs

     Research and development costs have been charged to operations as incurred.
SFAS No. 86, Accounting for the Costs of Computer Software To Be Leased, Sold,
or Otherwise Marketed, requires the capitalization of certain computer software
development costs incurred after technological feasibility is established.  The
Company believes that once technological feasibility of a software product has
been established, the additional development costs incurred to bring the product
to a commercially acceptable level are not significant.


     (i)  Foreign Currency Translation

     The Company considers the functional currency of its foreign subsidiaries
to be the local currency and, accordingly their financial information is
translated into U.S. dollars using exchange rates in effect at period end for
assets and liabilities and average exchange rates during each reporting period
for the results of operations.  Adjustments resulting from translation of
foreign subsidiary financial statements are included in stockholders' equity.


     (j)  Earnings Per Share

     Basic earnings per share was determined by dividing net income by the
weighted average shares of common stock outstanding during the year. Diluted
earnings per share reflects the potential dilution of stock options, based on
the treasury stock method.

          A reconciliation of basic and diluted weighted averages shares
outstanding is as follows:

     In 1999, 1998 and 1997, 1,657, 1,484 and 55 options to purchase common
shares, respectively, were not included in the diluted weighted average shares
outstanding, as they were antidilutive.


     (k)  Concentration of Credit Risk

     SFAS No. 105, Disclosure of Information About Financial Instruments with
Off-Balance Sheet Risk and Financial Instruments with Concentrations of Credit
Risk, requires disclosure of any significant off-balance sheet and credit risk
concentrations. Financial instruments that potentially expose the Company to
concentrations of credit risk consist primarily of cash and cash equivalents,
short-term investments and trade accounts receivable. The Company places its
temporary cash investments in several financial institutions. The Company has
not experienced significant losses related to receivables from any individual
customers or groups of customers in any specific industry or by geographic area.
Due to these factors, no additional credit risk beyond amounts provided for
collection losses is believed by management to be inherent in the Company's
accounts receivable. The Company had one customer with amounts due to the
Company of approximately 19% and 12% of total accounts receivable as of December
31, 1999 and 1998, respectively.


     (l) Derivative Financial Instruments and Fair Value of Financial
Instruments

     In June 1999, the Financial Accounting Standards Board (FASB) issued SFAS
No. 137, Accounting for Derivative Financial Instruments and Hedging Activities
- - Deferral of the Effective Date of FASB Statement No. 133, which defers the
effective date of SFAS No. 133 to all fiscal quarters of all fiscal years
beginning after June 15, 2000.  SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities.  It requires entities
to recognize all derivatives as either assets or liabilities in the statement of
financial position and to measure those instruments at fair value.  The Company
does not anticipate the adoption of these

statements to have a material impact on its financial position or results of
operations.  As of December 31, 1999, the Company did not have any derivatives
or other financial instruments as defined by SFAS No. 119, Disclosures About
Derivative Financial Instruments and Fair Value of Financial Instruments.

     SFAS No. 107, Disclosures About Fair Value of Financial Instruments,
requires disclosure of an estimate of the fair value of certain financial
instruments.  The Company's financial instruments consist of cash equivalents,
marketable securities, accounts receivable and accounts payable.  The estimated
fair value of these financial instruments approximates their carrying value at
December 31, 1999 and 1998 due to the short-term nature of these instruments.


     (m)  Comprehensive Income

     SFAS No. 130, Reporting Comprehensive Income, requires disclosure of all
components of comprehensive income on an annual and interim basis. The Company
adopted SFAS No. 130 and has disclosed comprehensive income for all periods
presented in the accompanying consolidated statements of stockholders' equity.


(2)  Acquisition of AnswerSoft, Inc.

     In May 1998, the Company acquired AnswerSoft, Inc. (AnswerSoft), a
Richardson, Texas, developer of inbound call center software solutions, in
exchange for the issuance of an aggregate of 2,384 shares of Davox common stock,
including shares which were subject to outstanding AnswerSoft, Inc. stock
options and warrants.  The acquisition was accounted for as a pooling of
interests under Accounting Principles Board Opinion No. 16.  Accordingly, the
historical consolidated financial statements for the periods prior to the merger
have been restated in the accompanying consolidated financial statements to
include the financial position, results of operations and cash flows of
AnswerSoft.  In connection with the merger with AnswerSoft, the Company incurred
non-recurring merger transaction costs (primarily professional fees) of $1,329.
In addition, the Company incurred non-recurring costs

(5)  401(k) Plan

     The Company maintains the Davox Corporation 401(k) Retirement Plan (the
Plan), which is a deferred contribution plan that covers all full-time employees
over 21 years of age.  Employees may join the plan in the next quarterly
enrollment period following their date of hire.  The participants may make
pretax deferred contributions to the Plan of up to 15% of the annual
compensation, as defined.  Contributions to the Plan by the Company are
discretionary and are determined by the Board of Directors.  The Company made
discretionary contributions to the Plan of approximately $777, $315 and $235 for

(6)  Income Taxes

     The Company accounts for income taxes using the liability method in
accordance with SFAS No. 109, Accounting for Income Taxes.  Under the liability
method specified by SFAS No. 109, a deferred tax asset or liability is
determined based on the difference between the financial statement and tax bases
of assets and liabilities, as measured by the enacted tax rates assumed to be in
effect when these differences are expected to reverse.

(6)  Income Taxes (continued)

     Approximately $4,811 and $4,887 of the deferred tax assets are classified
as current at December 31, 1999 and 1998, respectively. Approximately $1,198 and
$857 of the deferred tax assets are classified as long-term as of December 31,
1999 and 1998, respectively.

     At December 31, 1999, the Company has available net operating loss
carryforwards and tax credit carryforwards of approximately $962 and $1,762,
respectively.  The operating loss carryforwards and tax credit carryforwards
begin to expire in the years 2008 and 2000, respectively.

     In accordance with SFAS No. 109, the Company records a valuation allowance
against its deferred tax asset to the extent management believes it is more
likely than not that the asset will be realized. As of December 31, 1999, the
Company has provided a full valuation allowance against certain of the Company's
tax credit carryforwards due to the uncertainty of their realizability as a
result of limitations on their utilization in accordance with certain tax laws
and regulations. In 1998, a significan portion of the valuation allowance
related to the utilization of AnswerSoft's net operating loss carryforwards
(NOLs) due to limitations associated with these acquired NOLs. In 1999, the
Company implemented certain tax planning strategies that will result in the
Company being able to utilize substantially all of these acquired NOLs.
Accordingly, the Company reduced its valuation allowance in 1999 related to
these NOLs.

     A reconciliation of the federal statutory tax rate to the Company's
effective tax rate is as follows:

(8)  Preferred Stock

     Prior to the merger, AnswerSoft had two issues of preferred stock
outstanding, Series A Preferred Stock and Series B Preferred Stock or
collectively referred to as Preferred Stock. All shares of outstanding Preferred
Stock were converted to shares of Davox Common Stock upon approval of the merger
between the two companies in 1998.

(9)  Stockholders' Equity

     (a)  Stock Split

     During 1997, the Company effected a three-for-two stock split through the
issuance of a 50% stock dividend. All share and per share amounts have been
retroactively adjusted for the stock split.

     (b)  Note Receivable Due from Officer

     During 1997, AnswerSoft granted options to purchase 223 common shares with
an exercise price of $0.26 and 137 Series B preferred shares with an exercise
price of $2.60 to an officer of AnswerSoft as part of his employment with
AnswerSoft.  The options were exercised in 1997 in exchange for a promissory
note from the officer.  This note was repaid in full by the officer during 1998.

     (c)  1986 Stock Plan

     The Company's 1986 Stock Plan (the 1986 Plan), administered by the Board of
Directors authorizes the issuance of a maximum of 3,696 shares of common stock
for the exercise of options in connection with awards or direct purchases of
stock.  Options granted under the 1986 Plan may be either non statutory stock
options or options intended to constitute incentive stock options under the
Internal Revenue Code.  Stock options may be granted to employees, officers,
employee-directors or consultants of the Company and are exercisable in such
installments as the Board of Directors may specify.  The options granted
currently vest over a four-year period and expire ten years from the date of
grant.  As of December 31, 1999, there were options to purchase 616 shares
outstanding under this plan.  The 1986 Plan terminated pursuant to its terms in
September 1996.

     (d)  1994 Stock Plan

     In 1994, AnswerSoft's Board of Directors approved the adoption of an
employee stock option plan (the AnswerSoft Plan), as amended, which authorized
the grant of options to purchase up to 4,200 shares of AnswerSoft's common
stock.  The AnswerSoft Plan provided for the granting of options to eligible
employees to purchase AnswerSoft's common stock at an exercise price of not less
than 100% of the fair market value per share on the date of grant as determined
by AnswerSoft's Board of Directors.  The AnswerSoft Plan was administered by its
Board of Directors who determined the number of shares for which options will be
granted, the effective dates of the grants, the option price and vesting
schedules.  All options under the AnswerSoft Plan have a ten year term and
typically vested over four years from the effective date of the grant.  All
outstanding options became immediately and fully vested upon completion of the
merger with Davox.  The Company no longer grants options under the AnswerSoft
Plan.  As of December 31, 1999, there were eight options outstanding under the
AnswerSoft Plan.


     (e)  1996 Stock Plan

     The Company's 1996 Stock Plan (the 1996 Plan) administered by the Board of
Directors authorizes the issuance of a maximum of 2,700 shares of common stock
for the exercise of options in connection with awards or direct purchases of
stock.  Options granted under the 1996 Plan may be either nonstatutory stock
options or options intended to constitute incentive stock options under the
Internal Revenue Code. Stock options may be granted to employees, officers,
employee-directors or consultants of the Company and are exercisable in such
installments as the Board of Directors may specify. The options currently vest
over a four-year period. As of December 31, 1999, there were options to purchase
2,320 shares of common stock outstanding and 346 shares available for future
grants under the 1996 Plan.

     (h)  Employee Stock Purchase Plan

   The Company has an Employee Stock Purchase Plan (the Purchase Plan) under
which a maximum of 150 shares of common stock may be purchased by eligible
employees.  Substantially all full-time employees of the Company are eligible to
participate in the Purchase Plan. Shares are purchased through accumulation of
payroll deductions (of not less than 0.5% nor more than 10% of compensation, as
defined) for the number of whole shares, determined by dividing the balance in
the employee's account by the purchase price per share which is equal to 85% of
the fair market value of the common stock, as defined.  During 1999, 1998 and
1997, approximately 66, 21 and 12 shares, respectively, were purchased under the
Purchase Plan.

     (i) Accounting for Stock-Based Compensation

   The Company accounts for its stock-based compensation under Accounting
Principles Board Opinion No. 25, Accounting for Stock Issued to Employees.  In
October 1995, the FASB issued SFAS No. 123, Accounting for Stock-Based
Compensation, which established a fair-value-based method of accounting for
stock-based compensation plans.  The Company has adopted the disclosure-only
alternative under SFAS No. 123, which requires the disclosure of the pro forma
effects on earnings and earnings per share as if SFAS No. 123 had been adopted,
as well as certain other information.

   The Company has computed the pro forma disclosures required under SFAS No.
123 for all stock options granted (including shares issued under the employee
stock purchase plan) as of December 31, 1999, 1998 and 1997 using the Black-
Scholes option pricing model prescribed by SFAS No. 123.

(10) Segment and Geographic Information

     The Company adopted SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information, in the fiscal year ended December 31, 1998.
SFAS No. 131 establishes standards for reporting information regarding operating
segments in annual financial statements and requires selected information for
those segments to be presented in interim financial reports issued to
stockholders.  SFAS No. 131 also establishes standards for related disclosures
about products and services and geographic areas. Operating segments are
identified as components of an enterprise about which separate discrete
financial information is available for evaluation by the chief operating
decision maker, or decision making group, in making decisions how to allocate
resources and assess performance. The Company's chief decision-making group, as
defined under SFAS No. 131, is its executive management team. To date, the
Company has viewed its operations and manages its business as principally one
segment, software sales and associated services. As a result, the financial
information disclosed herein represents all of the material financial
information related to the Company's principal operating segment.

     Product revenues from international sources were approximately $10,800,
$9,700 and $14,700 in 1999, 1998 and 1997, respectively. The Company's revenues
from international sources were primarily generated from customers located in
Europe, Canada, Asia/Pacific and Latin America. All of the Company's product
sales for the years ended December 31, 1999, 1998 and 1997 were shipped from its
headquarters located in the United States.

     The following table represents the percentage of product revenue by
geographic region from customers for 1999, 1998 and 1997:

               ON FINANCIAL STATEMENT SCHEDULE



To Davox Corporation:

     We have audited, in accordance with generally accepted auditing standards,
the consolidated financial statements of Davox Corporation and subsidiaries
included in this Form 10-K and have issued our report thereon dated January 24,
2000.  Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The schedule listed in the index is the
responsibility of the Company's management and is presented for purposes of
complying with the Securities and Exchange Commission's rules and regulations
and is not part of the basic financial statements.  This schedule has been
subjected to the auditing procedures applied in the audits of the basic
financial statements and in our opinion, fairly states, in all material
respects, the financial data required to be set forth therein in relation to the
basic financial statements taken as a whole.

The foregoing shall in no way restrict DAVOX(R)'s right to solicit comparison
services and pricing from GSSC competitors in anticipation of a renewal or
termination of this Agreement nor restrict DAVOX(R)'s right not to renew this
Agreement upon any future expiration.

1.2  Subject to the provisions of Section 1.1 hereof, when DAVOX(R) has an
obligation to provide Maintenance Service (as defined in Exhibit `A') pursuant
to the terms and conditions of contracts by and between DAVOX(R) and its
Customers, DAVOX(R) shall appoint GSSC in accordance with the following:

     A.   DAVOX(R) shall appoint GSSC as its service representative to provide
          Maintenance Service for Customers located within the Territory. These
          Customers will be serviced from the city set forth in Exhibit F which
          is geographically closest to the System installation site (the
          "Service Cities").

     B.   Service Cities may be added to the GSSC Service City Schedule from
          time to time and GSSC shall provide DAVOX(R) with written notice
          within ten (10) days of such addition(s). In the event that a new

          necessary and appropriate research and financial analysis to determine
          the

                                       2                                05/17/99

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

          commercial practicality of such a request. GSSC shall honor such
          requests subject to such GSSC research findings and mutually agreeable
          terms between the parties.

     C.   Service Cities may be deleted from the GSSC Service City Schedule from
          time to time upon not less than ninety (90) day's prior written notice
          to DAVOX(R). In the event a Service City is deleted, GSSC and
          DAVOX(R) agree that Maintenance Service coverage may be handled, at
          DAVOX'(R)'s option, as follows:

     D.   (i)  GSSC shall continue to provide Maintenance Service coverage to
          Customers previously serviced from the deleted Service City utilizing
          resources from another Service City or other GSSC location. Such
          Service coverage will be made available for 12 months or through the
          end of any then current maintenance contracts between Customer and
          DAVOX(R)., whichever is less. Neither DAVOX(R) nor its Customers
          shall incur any additional charges for coverage furnished from an
          alternative location under this provision. DAVOX(R) shall use
          reasonable efforts to make any contract changes with its Customers
          which may be necessary to reflect that such Service shall be provided
          from GSSC's alternative location; or

     E.   (ii) DAVOX(R) shall have the right, without penalty, to make
          alternative arrangements for the provision of Maintenance Services to
          Customers who were previously serviced from such deleted Service
          Cities. Any such arrangements shall not be deemed a breach by
          DAVOX(R) of the exclusivity granted in Section 1.1 of this
          Agreement.

     F.   In the event that GSSC deletes a Service City or is in default of its
          obligation hereunder, or refuses to furnish Maintenance Services to a
          Customer, DAVOX(R) shall have the right, without penalty, to establish
          alternate forms of Maintenance Service coverage, including, without
          limitation, providing services itself or through a non-GSSC related
          third party service provider.

     G.   In the event a Customer requests that DAVOX(R) provide Maintenance
          Service directly and not through a third party, DAVOX(R) shall use its
          reasonable efforts to obtain Customer's permission for GSSC to
          directly contact Customer, in combination with DAVOX(R) sales
          personnel, for the purpose of promoting GSSC as DAVOX(R)'s service
          representative. In such case, DAVOX(R) will make reasonable efforts,
          as appropriate in DAVOX(R)'s determination, to encourage Customer to
          accept Maintenance Services through GSSC. Notwithstanding anything
          herein to the contrary, DAVOX(R) shall not be obligated to appoint
          GSSC as its service representative with respect to any Customer who
          has requested or who requests that DAVOX(R) provide maintenance
          directly and not through a third-party.

1.3  Products, subject to Maintenance Service under the terms of this Agreement,
will be added, deleted and/or revised under this Agreement by means of Work
Authorization Form prepared and signed by DAVOX(R) and submitted to GSSC.

2.0  TERM

determined as provided herein, this Agreement will have a term of three (3)

party will have the right to terminate this Agreement as of the end of the

   given Customer, GSSC will provide Maintenance Services for the Product
   situated at such Customer location. Each Work Authorization Form shall
   include all those Hardware components located at a specific Customer site and
   comprising a specific CAS or Unison system.

   Agreements. DAVOX(R) shall have the right, at its sole discretion, to
   modify the form of Maintenance Agreement at any time.

3. Customers will contact the DAVOX(R) Worldwide Support Center in Westford, MA
   (the "WSC") with all requests for Service.

4. Upon receipt of Customer's call to the WSC, DAVOX(R) will, prior to
   contacting GSSC, attempt to identify the cause of the problem reported by the
   Customer ("fault isolation") and will, as DAVOX(R) is reasonably able,
   instruct the Customer via telephone on steps to be taken to remedy the
   problem.

5. In the event DAVOX(R) determines that GSSC's on-site assistance is required
   to resolve a Customer Hardware problem (the "On-Site Service"), the WSC will
   contact the GSSC dispatch facility and request such on-site service via
   facsimile transmission, or electronic tasking (electronic-mail, system
   sharing), with voice confirmation, as mutually agreed to. A valid request by
   DAVOX(R) must include a Work Order Number, which must also appear on all
   documents relating to the Service call in question. The WSC is the only party
   that is authorized to initiate a Service call to GSSC on behalf of DAVOX(R)'s
   Customers.

6. Unless otherwise agreed to in writing, GSSC will use it's best efforts to
   provide a (4) hour response for all requests for On-Site Service called into

   from GSSC's receipt of request from DAVOX(R) to GSSC's arrival at Customer's
   site located within 50 miles of the nearest Service City (the "Response
   Time"). GSSC will use its best efforts not to exceed an eight (8) hour
   Response Time to Customers who are situated from 51 to 100 miles of the
   nearest Service City. On-Site Service requests for sites located beyond 100
   miles from a GSSC Service City will be responded to on a best effort basis.
   GSSC will use its best effort to arrive at the Customer's site as quickly as
   possible when the Customer status is identified by DAVOX(R) as being
   "critical"

   In the event a service request is made outside the contracted service period
   (i.e., PPM, PEM, as specified in Exhibit D), GSSC will use its best efforts
                                    ---------
   to comply with the Service request. GSSC reserves the right to comply with
   such requests for Service outside of the contracted Service periods, to the
   extent that reasonably necessary labor resources and parts are available. In
   all such instances, GSSC will use its best efforts to provide parts and labor
   from the nearest GSSC Service City.

   Service requests received by GSSC outside contracted business hours (as
   measured in the Service City) will be handled on a best effort basis.
   Extended Hours of Coverage are consecutive contract hours past the Principal
   Period of Maintenance (PPM) as defined in Exhibit D and incorporated herein
                                             ---------

     only after the initial PPM. Extended Hours of Coverage applies only to
     fully contracted Customers and shall be reserved for those occasions in
     which Severe Failures have occurred. "Severe Failures" are defined as
     "down" Systems; those failure types by which a System has lost the ability
     for more than half of the Customer agents to take inbound or outbound
     calls.

7.   GSSC will prepare and submit to DAVOX(R) a Field Service Activity Report or
     a system generated Service Management report for each Service call
     performed by GSSC (the "Service Activity Report"). With respect to those

     to DAVOX(R), as specified in Exhibit D, or when DAVOX(R) specifically
     requests, a Service Activity Report will be delivered to DAVOX(R) if
     specifically requested, GSSC will deliver to DAVOX(R) the Field Service
     Activity Report immediately upon completion of the service activity. Each
     such Service Activity Report will reference the Work Order Number as issued
     by DAVOX(R).

8.   GSSC will render Services in a professional and workmanlike manner so as to
     restore the Equipment to good working condition and will use its best
     efforts to maintain a courteous, positive customer service environment.

9.   Maintenance Service initiated during contracted business hours will
     continue for one hour past the PPM and will be treated as having been
     completed during contracted business hours at no additional cost to
     DAVOX(R). Maintenance Services continuing for more than one hour past the
     PPM will be billed at GSSC's then current Time and Materials rate.

10.  If engineering changes, feature changes, or safety changes are developed by

     installed by DAVOX(R) or if DAVOX(R) requests, GSSC will install such FCOs
     on a Per Call Services basis (per Exhibit D) or a mutually agreed to fixed
     fee basis. All components, parts and instruction packages necessary for
     GSSC to install FCOs will be delivered by DAVOX(R) to GSSC at no additional
     cost to GSSC.

11.  GSSC shall have no obligation to perform Services on Product if the End-
     User does not provide GSSC with reasonable access to the Product and a

     incorporated herein by reference and that such training classes are
     attended by its personnel in a timely manner.

     GSSC and DAVOX(R) agree that training requirements, as augmented throughout
     the term of this Agreement, will be addressed on a per incident basis and
     negotiated to the mutual satisfaction of both parties.

13.  GSSC will accept maintenance Service responsibility as of the effective
     date on the Work Authorization Form, a sample of which is marked as Exhibit

     necessary to terminate or suspend maintenance Service because of payment
     delinquency by its Customer, then the requirement for (30) day advance
     notice will be waived; such termination or suspension will be effective
     immediately upon notification to GSSC by DAVOX(R).

14.  In the event that any Product being maintained under the terms and
     conditions of this Agreement is relocated and such relocation is to a site
     serviced by a different Service City, GSSC will continue to maintain the
     Product at the new location if:

     a.  Such Product is installed by GSSC, or

     3.6. Year 2000 Date Change (Millennium Software Readiness) Upgrades

          This Statement of Work sets forth the agreement of the Parties as
          related to the software/hardware upgrade activity required to comply
          with DAVOX(R)'s Year 2000 Date Change ("Y2K") readiness requirements
          for DAVOX(R)'s Unison and In/Unison family of product(s).

          A.  Scope

           (1)  Each SUN Sparc and SUN Ultra computer system installed in
                DAVOX(R)'s Customers' Unison Call Center environment(s) will be
                required to be upgraded in order to accommodate the DAVOX(R)
                Year 2000 Date Change (the "Upgrade"). DAVOX(R) has estimated
                that this requirement currently represents approximately 170 SUN
                Ultra 3.X and 310 SUN Sparc 2.X systems.

           (2)  Each Upgrade will require an estimated 12-16 hours per SUN Sparc
                2.X system and 2-4 hours per SUN Ultra 3.X systems.

           (3)  A standard Upgrade will consist of:

                .  SUN Solaris 2.3 with Y2K software patches

                .  DAVOX(R) Unison software 2.3.0 with Y2K patches

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

                                      C-3
<PAGE>

                .  An initial `disk dump' backup before the start of an Upgrade;
                   and

                .  A full system back-up upon successful completion of an
                   Upgrade.

                .  SUN Ultra 3.X systems will also require a Sybase Y2K patch.

                .  Upgrade components, if any, for the SUN Sparc 10's and SUN
                   Classics will be determined by DAVOX(R) on or before
                   September 1, 1998.

All Upgrades will be completed by GSSC within a 10 month window beginning
September 1, 1998 and running through June 30, 1999.

The parties have agreed that 40-50% of all Upgrades are expected to be
accomplished outside the Principle Period of Maintenance as defined in the
Agreement.

GSSC is currently providing 4-5 non-Y2K software upgrades per week in addition
to its standard DAVOX(R) Product service delivery activities (remedial,
installation and MAC events). GSSC will provide sufficient resources to
accomplish at least 7 additional Upgrades for an expected total of 11-12
software upgrades per week.

B.  Software/Hardware Upgrade Components

     NOTE:  1.  Service delivered 100+ miles from a GSSC service center will
                receive travel hours one way.
            2.  Retainer pricing is monthly per service city. Wherein a service
                city meets the retainer fee through the uplifted sum of all the
                accounts in that particular service city, the retainer fee will
                be waived. For example; If a service city is receiving a $450/mo
                retainer fee and there are 18 accounts at a BMMC of @50 ea with
                a $25 (10%16) uplift, GSSC will waive the retainer fee. (18 x
                $25 = $450)
            3.  As an option, 6 x 16 coverage will be delivered from the closest
                GSSC service city with that capability, as indicated above.

                                   EXHIBIT E

              SCHEDULE OF CONSIGNED INVENTORY ("PARTS") SERVICES



1.   DAVOX(R) shall furnish, on a consigned basis and in the quantities mutually
     agreed upon by GSSC and DAVOX(R), all spare Hardware parts necessary for
     the maintenance of DAVOX(R) proprietary Hardware in accordance with this
     Agreement (the "Parts"). Quantity of Parts to be provided by DAVOX(R) shall
     be determined based on mutual agreement and shall consider Customer
     location, quantities of Customers within any given Service City service
     area, quantity and mix of DAVOX(R) product required to service such
     Customers, and actual usage experienced.

2.   The Parts shall at all times be subject to DAVOX's(R) direction and
     control. Upon termination of this Agreement, GSSC shall return all Parts
     then remaining in its possession to DAVOX(R).

3.   DAVOX(R) reserves the right to require GSSC to return for any reason any or
     all Parts then in GSSC's possession. DAVOX(R) reserves the right to verify
     the condition of any returned Parts through its own internal testing and
     inspection procedures, within five (5) business days of receipt.

4.   Any Part which has been damaged as a result of or due to GSSC's negligent
     act shall be paid for by GSSC but such damaged Part shall be returned to
     and shall become the property of DAVOX(R).

5.   During the term of this Agreement, GSSC will provide the following Parts
     services to DAVOX(R):

     a.   Maintain depots for stocking of Parts in select Service Cities and
          GSSC's National Logistics Stocking Depot, located in Longmont, CO.
          GSSC will keep records of the receipt, disbursement and use of such
          Parts;

     b.   Maintain all Parts in its possession or control as separate and
          distinct from any other parts belonging to any other party which may
          be held at the same location.

     c.   Utilize at least the same care and procedures, which shall in no event
          be less than reasonable care, in the safekeeping and record keeping of
          DAVOX's(R) Parts as it uses in maintaining its own parts and inventory
          records;

          Conduct annual inventories, at GSSC's expense of the Parts and provide
          DAVOX(R) with an inventory report immediately after its completion.
          GSSC will have ninety (90) days to reconcile any inventory
          discrepancies identified by DAVOX(R). GSSC's responsibility for
          unreconciled inventory discrepancies will be subject to a 3% annual
          industry standard shrinkage factor.

          In the event any discrepancy is identified by DAVOX(R) and
          unreconcilable by GSSC, GSSC shall reimburse DAVOX(R) for such missing
          Parts at DAVOX's(R) then current commercial price for same. GSSC
          agrees to permit, during its regular business hours and upon request
          by DAVOX(R), an annual on-site audit of any of GSSC

- --------------------------------------------------------------------------------
                                  Exhibit E-1
<PAGE>

          location where Parts are stocked. DAVOX(R) may request additional
          inventories to be taken and GSSC will comply at a mutually agreeable
          time.

     d.   If DAVOX(R) does not notify GSSC of any discrepancies within sixty
          (60) days of receipt of a reconciliation inventory report,
          specifically identifying any discrepancies, such inventories will be
          deemed to be conclusive and agreed to by DAVOX(R); GSSC will have no
          further liability for any future discrepancies which may be identified
          with respect to the specific inventory and levels referenced therein.
          Procure and maintain sufficient inventory to support OEM Equipment and
          comply with such Equipment manufacturer's requirements related
          thereto.

     e.   Replenish and/or expand the inventory of Parts as mutually agreed to
          by DAVOX(R) and GSSC.

     f.   Provide to DAVOX(R) Part Usage Reports and Material & Service
          Measurements (the "Metrics") pursuant to Exhibit N and as mutually
          agreed to by DAVOX(R) and GSSC.

     g.   Provide Parts control and management staff ("Logistics") Monday
          through Friday 6AM to 6PM, Mountain Time, and pager availability of
          standby Logistics personnel on all remaining days and times at GSSC's
          National Logistics Stocking Depot located in Longmont, CO. to ensure
          that DAVOX(R) has year-round access to the Parts 24 hrs/day, 7
          days/week.

6.   During the term of this Agreement and any extensions thereof, when DAVOX(R)
     has been informed that Parts have been used to replace a faulty DAVOX(R)
     proprietary component, board, subassembly, or assembly at a DAVOX(R)
     Customer site, DAVOX(R) will express ship a replacement to GSSC at no cost
     to GSSC. The replaced faulty part shall be shipped to DAVOX(R) at
     DAVOX's(R) expense within ten (10) days of GSSC's receipt of the
     replacement Part. GSSC will utilize this program to repair and/or replace
     failed DAVOX(R) proprietary Hardware at no cost to GSSC. DAVOX(R) shall be
     responsible for all costs related to shipping, handling, taxes, and in-
     transit insurance.

7.   Title in and to all Parts shall remain vested in DAVOX(R) until such Parts
     are actually installed at a Customer site. Upon such installation, title to
     such Part(s) shall automatically transfer to such Customer. Notwithstanding
     the foregoing, GSSC shall be and shall remain responsible for the
     safekeeping and handling of any Parts while such Parts are in its
     possession or control. Title to any Hardware or component part thereof
     which GSSC may replace with a Part shall vest in DAVOX(R) immediately upon
     GSSC's removal of such Hardware or component part from the Customer's
     System installation.

     GSSC will not acquire nor be granted any right, title or interest in or to
     any equipment or to any spare Parts which DAVOX(R) may supply unless GSSC
     specifically purchases them. GSSC will bear the risk of all loss or damage
     with respect to equipment and Parts in GSSC's possession.

8.   Subject to GSSC's inventory maintenance obligations set forth above, in the
     event that Parts supply commitments described in this Agreement are not
     maintained by DAVOX(R) and it becomes necessary for GSSC to notify DAVOX(R)
     that one or more Parts are required for an emergency, then DAVOX(R) will
     take reasonably prompt action to ship the Parts required by GSSC, at
     DAVOX's(R) expense, by the best method as determined by DAVOX(R) and to
     such location as may be mutually agreed upon by DAVOX(R) and GSSC within 24
     hours of receipt

- --------------------------------------------------------------------------------
                                  Exhibit E-2
<PAGE>

     of such notice from GSSC. In such event, the measurement of GSSC's response
     time shall commence upon receipt of such emergency Parts at the location to
     which the parties agreed the Parts would be delivered.

9.   GSSC will not be obligated to respond to any service requests unless
     sufficient Parts are available to the responding GSSC engineer either at
     the GSSC Service City office location or at the Customer site provided,
     however, that GSSC has notified DAVOX(R) of its requirements pursuant to
     paragraphs 1 and 8 above and provided further that DAVOX(R) has failed to
     respond accordingly.

10.  The cost of repair, transportation and handling of Parts to and from
     DAVOX(R) shall be paid by DAVOX(R). For non-proprietary OEM Equipment
     parts, the cost of repair, transportation and handling will be at no cost
     to DAVOX(R) and will be the responsibility of GSSC.

11.  Within thirty (30) days of expiration or termination of this Agreement,
     GSSC will provide DAVOX(R) with a final written reconciliation inventory,
     together with the return shipment of remaining Parts and any other
     materials, Hardware, Software, documentation, and any other DAVOX(R)
     property then in GSSC's possession or control, to DAVOX(R) at DAVOX's(R)
     expense. GSSC shall, however, be responsible for packing all such Parts and
     other materials in such a manner so as to reasonably ensure their safety
     and security during transit.

12.  GSSC shall conduct all Hardware repairs contemplated hereunder in
     accordance with the OEM Equipment manufacturer's recommended diagnostic
     processes and procedures and troubleshooting guidelines. Where whole unit
     system exchanges are requested by DAVOX(R), DAVOX(R) will assume all costs
     associated with the whole unit exchange unless in the course of repair,
     GSSC and DAVOX(R) mutually agree that a whole unit exchange is necessary
     and required.

14.  OEM spare equipment/component part stocking is based on a minimum install
     base of equipment(s) and whereby minimum quantities of like product exist
     in geographical densities. GSSC employs a single central stocking approach
     to products and components with insufficient install base or insufficient
     geographical distributions. Where new products are introduced with
     Indefinite Deliveries and Indefinite Quantities GSSC will initially stock
     spare components at its National Logistics Center in Longmont, CO.

15.  Where DAVOX(R) employs equipment that requires identical component exchange
     and where specific manufacturer and model number are not provided per the
     work authorization form and where the use of components equivalent in
     operation and manufacturer support are prohibited, GSSC and DAVOX(R) agree
     to mutually develop a stocking and sparing implementation approach and
     plan.

                                   DISPATCH

GSSC and DAVOX(R) have mutually agreed on the process and procedures by which a
Service request is dispatched by DAVOX(R) to GSSC (the "Dispatch Process") and
the dispatch dynamics thereof, Exhibit J-1 details the ETA process and is
                               -----------
attached hereto and incorporated herein by reference.

1.  Service, Installation and MAC activity requests are accepted by GSSC only
from authorized and identified DAVOX(R) representative(s).

2.  At a minimum, DAVOX(R) will provide the Customer Site name, Site address,
Site contact and phone number, equipment type to be serviced, description of
problem or requested activity, recommended or implicated failing component (if
applicable), DAVOX(R) support/management contact (if applicable), DAVOX(R) site
code, GSSC site contract number and any and all special instructions as
applicable.

3.  GSSC staffs its Customer Service Center 7 days per week, 24 hours per day

personnel any day or time and will dispatch within that Customers contracted
PPM.  In those instances where requests for services are outside the PPM, are
dispatched by DAVOX(R) and are not considered a scheduled activity, will be
invoiced at the Time and Material Rates as stated in Exhibit D, paragraph B.

4.   GSSC and DAVOX(R) are currently seeking to develop a consolidation of their
respective Service Management Systems. It is anticipated that an electronic
merge of DAVOX's(R) and GSSC's service management systems will eventually allow
GSSC direct communication in providing ETA, Update and Call Closure information
directly to DAVOX's(R) management system. Additionally, it is anticipated that
dispatches will be directly and electronically sent by DAVOX(R) and received by
GSSC, for dispatch to GSSC's field service organization.

                            INSTALLATION CHECKLIST


I.  Purpose

The Unison installation checklist is to be used by all those involved in the
integration of a UNISON call center and in order to communicate the successful
implementation and/or to highlight any and all discrepancies as a result of an
installation effort.

Additionally, the checklist will provide the necessary metrics to assist DAVOX
(R) System Integration Managers (SIM) in accomplishing their tasks along with
serving as a performance metric in achieving the goals and milestones
established by GSSC and DAVOX(R).

The checklist also provides installation personnel a guideline in performance
expectations and specific task requirements necessary to integrate a UNISON call
center.

II. Procedure

Prior to starting any Unison integration the installers should have a site
specification inventory, provided by the DAVOX(R)(R) System Integration Manager
(SIM) defining the system layout and configuration.

During a UNISON install activity service installation personnel will use, as a
guideline and task execution document, the Grumman Physical Layer Install
checklist.  As items are attempted or successfully concluded they should be
checked off indicating that particular task(s) completion.

Immediately upon completion of the checklist and inventory a copy should be
faxed to Bob Lennon at DAVOX(R) headquarters in Westford, MA at 508 952-0206.
Bob will distribute copies as necessary to all cognizant personnel.

A copy is to be left on site for the SIM and be included as part of that
particular sites log.  GSSC install personnel should provide a folder for this
and include all relevant documentation as it pertains to the site.

                 DAVOX CORPORATION EXECUTIVE COMPENSATION PLAN

     The compensation arrangements between Davox Corporation (the "Company") and
each of its executive officers are based on the Company's Executive Compensation
Plan (the "Plan"), the terms of which are described herein.

     The Company's executive compensation program is administered by the two
member Compensation Committee of the Board of Directors (the "Compensation
Committee"). The two members of the Compensation Committee are non-employee
Directors. Pursuant to the authority delegated by the Board of Directors, the
Compensation Committee establishes each year the compensation of the Chief
Executive Officer, and together with the Chief Executive Officer, establishes
the compensation of the other executive officers of the Company pursuant to the
Plan.

     The Plan is designed to reward executive officers whose performance yields
improvement in corporate operating results, market share and shareholder value.
The ultimate goal of the Plan is to align the interests of management with those
of the stockholders. Compensation under the Plan is comprised of cash
compensation in the form of annual base salary, incentive compensation in the
form of performance-based cash bonuses, and long-term incentive compensation in
the form of stock options.

     In setting cash compensation levels for executive officers, the
Compensation Committee takes into account such factors as: (i) the Company's
past financial performance and future expectations, (ii) the general and
industry-specific business environment, and (iii) corporate and individual
performance goals. The base salaries are established at levels comparable to the
amounts paid to senior executives with comparable qualifications, experience and
responsibilities at other companies located in the northeastern United States of
similar size and engaged in a similar business to that of the Company.

     Incentive compensation in the form of performance-based bonuses for the
Company's executive officers is based upon management's success in meeting the
Company's financial and strategic goals as well as meeting individual
performance goals. Target levels of revenue and net income are set annually, and
bonuses are allocated to the executive officers contingent upon the achievement
of the target levels. In addition, based on the Company's exceeding both target
revenues and target net income, additional bonuses are awarded to executive
officers in the same proportion as bonuses are allocated under the Plan.

     Incentive compensation in the form of stock options is designed to provide
long term incentives to executive officers, to encourage the executive officers
to remain with the Company and to enable optionees to develop and maintain a
significant, long-term stock ownership position in the Company's Common Stock.
The Compensation Committee grants stock options to the Company's executive
officers in consideration of the strategic goals and direction of the Company.

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

     THIS AGREEMENT ("Agreement") is made and entered into by and between Kana
Communications, Inc., a Delaware corporation with its principal offices located
at 87 Encina Avenue, Palo Alto, CA 94301 ("Kana"), and Davox Corporation, a
Delaware corporation with its principal offices located at 6 Technology Park

                                   --------

     WHEREAS, Kana manufactures, sells, licenses, supports, maintains and/or
otherwise distributes products and desires to grant OEM the right to sell,
sublicense, install, support and/or maintain one or more of those products (as
hereinafter defined) upon the terms and conditions set forth below,

     NOW THEREFORE, in consideration of the mutual covenants and agreements set
forth below, the parties agree as follows:

1.  DEFINITIONS

    a.  "Bundled Product" shall mean the Ensemble Customer Contact Suite
        offering or other OEM product offered to OEM 's End-Customers containing
        Software.

    b.  "Software" shall mean all software designated in Exhibit A, and all
        related documentation provided therewith. Kana reserves the right to
        make deletions, additions, substitutions and modifications to the
        Software in its sole discretion upon not less than ninety (90) days
        prior written notice.

    c.  "Specifications" shall mean those portions of Kana's published materials
        made available for distribution with the Software and which describe the
        specific functionality of the Software.

    d.  "End-Customer" shall mean a purchaser and/or OEM of any Software for
        such purchaser's and/or OEM's actual use and not intended for resale.

    e.  "Territory" shall mean worldwide.

2.  LICENSE. Subject to the terms of this Agreement, Kana grants to OEM a
    nontransferable, nonsublicensable, nonexclusive, limited license to use the
    Software only in the Territory and in accordance with the documentation
    supplied by Kana only for the purpose of demonstrating the software in
    object code form only to potential End-Customers.

3.  OEM LICENSE.

    a.  Subject to the terms of this Agreement, Kana also grants to OEM a
        nontransferable, nonexclusive, limited license to sublicense the
        Software only as part of a Bundled Product, only in the Territory in
        object code form only to End-Customers, either directly or through its
        distribution partner ("OEM Partners"), for use only within the
        Territory. Each product licensed by OEM that incorporates Software shall
        be distributed by OEM only pursuant to an End-Customer License Agreement
        signed by End-Customer prior to distribution of the Bundled Product to
        that End-Customer, and which shall provide at as least much protection
        to Kana as the terms of this Agreement. OEM agrees that in the event
        such license is breached by an End Customer and such breach impacts
        Kana's proprietary interests, it shall either: (i) enforce the End-
        Customer License Agreement in order to protect the proprietary rights of
        Kana hereunder, or (ii) in the event OEM fails to enforce such End-
        Customer License Agreement to protect Kana's proprietary rights
        hereunder, then to the extent legally

                          Software Support Agreement

                                                                          Page 1
<PAGE>

        permitted OEM hereby assigns its rights under such Sublicense Agreement
        to Kana, but only to the extent necessary to protect Kana's rights
        hereunder.

    b.  OEM may use its OEM Partners to distribute the Bundled Product provided
        that OEM's obligations hereunder are not diminished, and OEM shall
        ensure that such OEM Partners have entered into distribution agreements
        that are at least as protective of Kana's interests hereunder with
        comparable training, service, support and similar requirements. OEM
        agrees that in the event such distribution agreement is breached by an
        OEM Partner and such breach impacts Kana's proprietary and other
        interests, it shall either: (i) enforce such distribution agreement in
        order to protect the proprietary rights of Kana hereunder, or (ii) in
        the event OEM fails to enforce such distribution agreement to protect
        Kana's rights hereunder, then to the extent legally permitted OEM hereby
        assigns its rights under such distribution agreement to Kana, but only
        to the extent necessary to protect Kana's rights hereunder.

4.  OWNERSHIP.

    a.  OEM may not decompile, reverse engineer or modify the Software, or
        create derivative works therefrom and, except as described otherwise in
        this Agreement, shall be bound by the terms herein. Notwithstanding the
        foregoing, Kana grants OEM the right to integrate the Software within
        OEM's software and products, subject to Kana's rights in the Software.

    b.  Notwithstanding the foregoing, and unless otherwise mutually agreed upon
        in writing by the parties, to the extent that OEM conceives, learns, or
        reduces to practice any work of authorship, idea or know-how (whether or
        not patentable) directly derived from or directly relating to the
        Software in the course of performance under this Agreement ("Work
        Product") OEM hereby assigns such Work Product to Kana and any patent
        rights, copyrights (including moral rights; provided that non-assignable
        moral rights are waived to the extent permitted by law), trade secret
        rights, and other rights with respect thereto. OEM agrees to take any
        action reasonably requested by Kana to evidence, perfect, obtain,
        maintain, enforce or defend the foregoing at Kana's cost.

    c.  OEM agrees that to the extent that any rights in any Work Product,
        directly derived from or directly relating to the Software, are not
        assigned to Kana hereunder:

        i.  OEM grants to Kana a world-wide permanent, irrevocable, royalty-
            free, unlimited, fully paid-up license to such Work Product;

        ii. OEM agrees not to assert, file or otherwise raise any claim or
            action against Kana for the infringement of any rights of OEM in
            such Work Product, directly derived from or directly relating to the
            Software; and

    d.  OEM agrees that each copy of any Software, documentation, and all
        packaging media used for their distribution, shall include reproductions
        of the copyright notices and other proprietary legends of Kana as Kana
        designates, in computer object code format or otherwise, which accompany
        such items. OEM shall not remove, efface or obscure any copyright
        notices or other proprietary notices or legends from any Kana materials
        provided herein. Subject to the foregoing, OEM is permitted to, at its
        own cost, brand the Bundled Software under its trademark, tradename and
        other marks and names owned by OEM, including, without limitation,
        developing packaging, documentation, marketing collateral splash
        screens, and similar items with OEM's brand.

    e.  Any symbols, trademarks and service marks adopted by Kana to identify
        the Software ("Trademarks") belong to Kana and OEM shall have no rights
        in such Trademarks except as

                           Kana Communications, Inc.
                          Software Support Agreement

                                                                          Page 2
<PAGE>

        expressly set forth herein. OEM shall use such Trademarks only in
        accordance with Kana's guidelines for use of the Trademarks. Any
        symbols, trademarks and service marks adopted by OEM to identify the
        Bundled Product belong to OEM and Kana shall have no rights in such
        Bundled Product trademarks except as expressly set forth herein. Kana
        shall use such Bundled Product trademarks only in accordance with OEM's
        guidelines for use of such trademarks.

5.  NON-EXCLUSIVITY BY KANA. Kana may appoint other companies to purchase,
    resell, license, sublicense, install, support, maintain and/or otherwise
    distribute one or more of its Software, including without limitation, those
    that may compete with OEM. Kana reserves the sole and exclusive right to
    solicit, authorize, approve, disapprove or terminate any current or
    prospective OEM. Nothing in this Agreement shall be construed to prohibit
    Kana from selling, licensing, sublicensing, installing, supporting,
    maintaining and/or otherwise distributing its Software directly, indirectly,
    or through other channels.

        related to these copies, to the extent ordered, shall be charged the fee
        specified on Exhibit A.

    f.  As provided herein, Kana shall respond promptly to reports from OEM of
        End-Customer or OEM complaints, concerns or problems concerning the
        Software.

    g.  Subject to mutual agreement on integration, cost and support issues, OEM
        shall have the opportunity to bundle any improvements or modifications
        to the Software and new products offered by Kana.

    h.  Kana agrees to provide and maintain an application programmer interface
        (API) into the Software that will allow its integration with Davox's
        Ensemble. The parties will work together to develop a mutually agreed
        upon specification, including a schedule for availability, which will be
        completed and delivered to Davox by Nov. 30, 1999. Kana will use
        commercially reasonable efforts to meet the terms of that schedule.

8.  INTEGRATION.

    a.  The parties shall cooperate with one another in good faith in order to
        complete the integration of the Software into OEM's Ensemble customer
        contact suite or other OEM product(s). Each party shall make available
        in a timely manner at no charge to the other party all technical data,
        files, documentation, sample output, or other information and resources
        reasonably required by the requesting party for the performance of the
        Integration Services. All such technical data, files, documentation,
        sample output, or other information and resources shall be deemed
        Confidential Information as defined hereunder.

<PAGE>

    i.  Tasks that are primarily the responsibility of OEM's personnel will
        remain OEM's responsibility and will remain under OEM's supervision,
        management and control, even if Kana assists OEM in performing such
        tasks. OEM shall reasonably cooperate with Kana and provide such
        reasonable assistance as both parties may reasonably determine, in
        connection with Kana's efforts to obtain all consents, approvals and
        authorizations of and cooperation from third parties needed by Kana to
        effectuate the transactions contemplated hereby and give all reasonable
        notices to third parties which may be reasonably necessary or reasonably
        required in order to effectuate the transactions contemplated hereby.
        OEM and Kana each shall bear any costs resulting from the other's
        failure to meet these obligations.

9.  SUPPORT. OEM shall provide pre and post-installation support and service for
    the Software to OEM's End-Customers in accordance with Exhibit B. OEM's
    support obligations shall be undertaken only by personnel who have completed
    Kana's training and have obtained Kana's authorization. OEM shall provide
    support at the response levels described in Exhibit B attached hereto.
    Subject to payment of the appropriate support fees set forth in Exhibit A,
    Kana shall provide technical support as described in Exhibit B.

10. PAYMENT

    a.  OEM shall pay Kana the OEM Fee as set forth in Exhibit A and Exhibit A-1
        for each copy of the Software and maintenance services that it sub-
        licenses to End-Customers pursuant to this Agreement. OEM's payments of
        Fees hereunder shall be due and payable forty-five (45) days after the
        date of Kana's invoice, which invoice shall not be issued (i) for
        Licenses, Professional Services and Training until after the date of the
        applicable order from OEM; and (ii) for Maintenance and Support, until
        the end of the warranty period set forth in Section 16(a) of this
        Agreement. Along with such payment, OEM shall provide Kana with a
        detailed report of all Software licensed, maintenance contracts signed
        and other services provided to any party which OEM is required to
        furnish payment to Kana. Such report shall include information
        reasonably available to OEM, including, by way of example, and without
        limitation, the name of each End-Customer, the location of each
        installation and instance of each piece of Software, and other
        information as may be reasonably requested by Kana and agreed to by OEM.

    b.  Kana reserves the sole right to change the "OEM Fee" for any Software
        after the second (2/nd/) year of the Initial Term in a manner consistent
        with changes to Kana's standard price list Kana will provide OEM with
        not less than ninety (90) days prior written notice of any such change.

    c.  The payment method hereunder will be as Kana reasonably directs from
        time to time. All License and OEM Fees are exclusive of shipping, taxes,
        duties and the like, which shall be paid by OEM. All undisputed late
        payments (i.e., payments that have not been received by Kana within
        thirty (30) days from the date OEM receives written notice of such
        payment being late) shall be assessed a service charge of 1.5% per month
        to the extent allowed by law. For international shipments, outside the
        United States, OEM will be responsible in advance for all applicable
        shipping charges, taxes, customs charges, duties, brokerage fees or
        common carrier charges.

    d.  OEM shall keep, maintain and preserve for at least three (3) years
        following termination or expiration of the term of this Agreement or any
        renewal(s) thereof, accurate records relating to OEM's obligations
        hereunder. Such records shall be maintained as Confidential Information,
        but shall be available for inspection and audit as provided herein. Kana
        shall have the right at least once per calendar year to have an
        independent public accountant, reasonably acceptable to OEM, examine
        OEM's relevant books, records and accounts

                           Kana Communications, Inc.
                          Software Support Agreement

                                                                          Page 5
<PAGE>

        specifically relating to this Agreement for the purpose of verifying the
        accuracy of payments made as required under this Agreement. Such
        independent public accountant must agree in writing to be bound to the
        confidentiality provision contained in this Agreement. Kana acknowledges
        and agrees that such accountant shall not have access to the books,
        records, and accounts relating to other products or services except as
        such books, records and accounts also directly relate to the payments
        due hereunder. Each audit will be conducted at OEM's place of business,
        or other place agreed to by the Parties, during OEM's normal business
        hours and with at least thirty (30) days prior written notice to OEM.
        Kana shall pay the fees and expenses of the auditor for the examination;
        provided that should any examination disclose a greater than five
        percent (5%) shortfall in the payments due Kana for the period being
        audited, OEM shall pay the reasonable fees and expenses of the auditor
        for that examination.

11. TERM AND TERMINATION

    a.  The term of this Agreement shall be for a period of five (5) years,
        beginning on the date this Agreement is executed by OEM ("Effective
        Date"). Thereafter, this Agreement shall be renewed for successive one
        (1) year terms without further notice, unless terminated sooner as
        provided under the provisions herein, or unless either party elects not

        ii.  shall cease conducting business in the normal course, become
        insolvent, make a general assignment for the benefit of creditors,

        assets, or shall avail itself of or become subject to any proceeding
        under the Federal Bankruptcy Act or any other federal or state statute
        relating to insolvency or the protection of rights of creditors;

        iii.  is unable or unwilling to provide Software support to End-

        or any of its rights hereunder to any other party without the prior
        written approval of Kana or as otherwise permitted in this Agreement; or

        vi.  OEM fails to pay to Kana the Fees in the amounts and schedule set
        forth in Exhibit A hereto and fails to cure such breach within thirty
        (30) days of Kana's notice to OEM of such breach).

        vii.

<PAGE>

    c.  Upon the occurrence of an event of default as described in Section 11(b)
        by OEM, Kana may immediately terminate this Agreement by providing
        written notice of such termination to OEM.

    d.  During the first two years of this Agreement, in the event Kana seeks to
        assign this Agreement to any of the following competitors of OEM -
        Genesys/Alcatel, Cisco/Geotel, Lucent, Aspect, Interactive Intelligence,
        Apropos, eShare, EIS, Quintus, Kana shall notify OEM of Kana's intent to
        assign, including the identity of the proposed assignee. OEM shall then

        such termination to be effective immediately. Upon such termination, OEM
        shall have no obligation with respect to any Minimum Commitments
        following the termination date.

    e.  Upon termination or expiration of this Agreement by either party
        pursuant to the provisions set forth herein, the following provisions
        shall apply:

        i.   After termination, Kana shall not be required to accept purchase
             orders or make any shipments to OEM, and Kana reserves the right to
             require advance payment, or other agreed arrangements, for any
             shipments made or service performed.

        ii.  Following termination or expiration of this Agreement, Kana shall
             continue to honor its maintenance and warranty obligations as
             provided for in this Agreement with regard only to Software sold by
             OEM prior to the date of termination or expiration. Kana will
             continue to provide maintenance service to any end user that OEM
             has registered with Kana until such obligation ends. Thereafter,
             Kana agrees to offer support to OEM at then current Kana rates and
             terms for a period of two (2) years. Thereafter, OEM shall, at its
             sole discretion, direct End-Customers to purchase support services
             directly from Kana. To the extent End-Customer enters into a
             maintenance and support agreement with Kana, Kana shall provide
             maintenance support to such End-Customer.

        iii. The expiration and/or termination of this Agreement shall not alter
             the rights, duties or obligations of the parties under this
             Agreement including without limitation payment obligations, which

             entire amount shall be due in full within ten (10) business days of
             termination.

        iv.  Following termination, OEM shall be entitled to deploy any copies
             of prepaid but undeployed Software, including any related
             documentation and supporting materials. To the extent OEM desires
             to take additional training or obtain maintenance and support for
             such Software deployments after termination, such fees will be at
             the then current list prices for such services.

12. TRADEMARKS, PRODUCT MARKINGS AND GOODWILL

    a.  OEM acknowledges that the marks "Kana", "Kana CMS", Kana logo, and all
        other trademarks, trade names or service marks that Kana may designate
        from time to time (the "Marks"), and all registrations thereof, are good
        and valid and are solely and exclusively owned by Kana. OEM agrees that
        it will use and display the Marks only in the form or for the purposes
        authorized by Kana in this Agreement. OEM further acknowledges that this
        Agreement does not grant OEM any right, title or interest in the Marks
        or goodwill associated with Kana and the Software as represented and
        symbolized by the Marks.

    b.  OEM shall not take any action, or fail to take any action, during or
        after the term of this Agreement, which could adversely affect the
        validity or enforceability of Kana's Marks.

<PAGE>

    c.  In order to preserve and protect the goodwill, reputation and image of
        Kana and the Software, OEM shall:

        i.   Not engage in any deceptive, misleading or unethical practices,
             which are or might be detrimental to Kana or the Software;

        ii.  Refrain from making any false, misleading or deceptive
             representations with regard to Kana or the Software; and

        iii. Refrain from making any representations, warranties or guarantees
             to Customers or prospective Customers or other third parties with
             respect to the specifications, features or capabilities of the
             Software that are inconsistent with the literature or other
             information provided or prepared by Kana.

    d.  Immediately following the expiration or termination of this Agreement
        for any reason, OEM shall discontinue use of the aforementioned Marks
        and return, or dispose of, as Kana may direct, any signs or other
        promotional displays directly or indirectly referencing or relating to
        Kana and/or any of the Software or Marks. If, after expiration or
        termination of this Agreement, OEM makes any further use of the Marks,
        except as necessary to complete any ongoing obligations under this
        Agreement, such use shall be deemed a breach of this Agreement for which
        no adequate remedy at law exists. In such case, Kana may be entitled to
        seek immediate injunctive relief from an appropriate court. This
        provision shall not apply to any Bundled Products or related
        documentation delivered to OEM as a result of a prepaid license fees, as
        a result of unfulfilled orders, or the provision of support as described
        in Section 11(e)(ii) or 11(e)(iv).

13. TRAINING.

    a.  An appropriate number of personnel of OEM engaged in the sales, support,
        development or maintenance of the Software shall obtain the appropriate
        Kana Qualification. Kana Qualification is obtained by completing Kana's
        training requirements as currently defined by Kana in Exhibit C, and as
        otherwise generally required of partners under the Kana partner
        programs.

    b.  Kana shall make available its standard training program to the number of
        employees of OEM set forth in Exhibit C hereto. OEM may purchase
        training for additional employees at the rate set forth in Exhibit C.
        All out of pocket costs, including without limitation costs associated
        with travel to the training location, are at the expense of OEM.

14. INDEMNIFICATION

    a.  Kana agrees, at its own expense, to defend or, at its option, to settle,
        any claim or action brought against OEM or any End-Customer to the
        extent it is based on a claim that the Software as used within the scope
        of this Agreement infringes or violates any copyright, trademark, trade
        secret or U.S. patent of a third party, and will indemnify and hold OEM
        and such End-Customer harmless from and against any damages, costs and
        fees reasonably incurred (including reasonable attorneys' fees) by or
        which are assessed against OEM or such End-Customer that are directly
        attributable to such claim or action. OEM agrees that Kana shall be
        released from the foregoing obligation unless OEM or such End-Customer
        provides Kana with: (i) prompt written notification of the claim or
        action once it becomes aware; (ii) sole control and authority over the
        defense or settlement thereof; and (iii) at cost to Kana, all reasonably
        available information, assistance and authority to settle and/or defend
        any such claim or action, except that Kana may not enter into any
        settlement of any claim hereunder which settlement shall subject OEM and
        such End-Customer to any liability

                          Software Support Agreement

                                                                          Page 8
<PAGE>

     or obligations unless OEM approves such settlement agreement in writing,
     which approval shall not be unreasonably withheld. Notwithstanding the
     foregoing, Kana shall have no liability hereunder based on (i) use of a
     superseded or modified release of the Software, except for such
     alteration(s) or modification(s) which have been made by Kana or under
     Kana's direction, if such infringement would have been avoided by the use
     of a current unaltered release of the Software that Kana provided to OEM or
     such End-Customer prior to OEM or End-Customer's receipt of such threat or
     claim, or (ii) the combination, operation, or use of any Software furnished
     under this Agreement with programs not furnished by or approved by Kana if
     such infringement would have been avoided by the use of the Software
     without such programs. In the event that an injunction is obtained against
     OEM or such End-Customer prohibiting use of the Software by reason of
     Kana's infringement of a patent, copyright or other intellectual property
     right of any third party, Kana will, at its option and expense, either (a)
     secure for OEM and such End-Customer the right to continue using the
     Software; (b) replace or modify the Software to make it non-infringing, but
     functionally equivalent; or, if neither of the foregoing are available on
     commercially reasonable terms as determined solely by Kana in its
     reasonable opinion (c) direct OEM and such End-Customer to discontinue
     using the Software, and provide OEM or such End-Customer with a refund of
     all monies paid by OEM or such End-Customer within the forty-eight (48)
     months prior to such injunction.

  b. OEM agrees, at its own expense, to defend or, at its option, to settle, any
     claim or action brought against Kana to the extent it is based on a claim
     that the Bundled Product infringes or violates any copyright, trademark,
     trade secret or U.S. patent of a third party, and will indemnify and hold
     Kana harmless from and against any damages, costs and fees reasonably
     incurred (including reasonable attorneys' fees) by or which are assessed
     against Kana that are directly attributable to such claim or action . Kana
     agrees that OEM shall be released from the foregoing obligation unless Kana
     provides OEM with: (i) prompt written notification of the claim or action;
     (ii) sole control and authority over the defense or settlement thereof; and
     (iii) at no cost to OEM, all reasonably available information, assistance
     and authority to settle and/or defend any such claim or action, except that
     OEM may not enter into any settlement of any claim hereunder which
     settlement shall subject Kana to any liability or obligations unless Kana
     approves such settlement agreement in writing, which approval shall not be
     unreasonably withheld. Notwithstanding the foregoing, OEM shall have no
     obligation under this Section (b) to the extent such infringement would
     have arisen from use of the Software alone or in combination with other
     items provided or approved by Kana, other than items supplied by OEM. OEM's
     obligation under this Section (b) shall not restrict or limit Kana's
     obligations under Section 14(a).

15.  CONFIDENTIALITY AND NON-DISCLOSURE

  a. Each party (the "Receiving Party") acknowledges that, during the term of
     this Agreement, it may receive from or on behalf of the other party (the
     "Disclosing Party"), information relating to the Disclosing Party
     ("Confidential Information"). Such Confidential Information shall belong
     solely to the Disclosing Party and includes, but is not limited to, this
     Agreement, trade secrets, know-how, inventions (whether or not patentable),
     techniques, processes, programs, ideas, algorithms, schematics, testing
     procedures, software design and architecture, computer code, internal
     documentation, design and function specifications, product requirements,
     problem reports, analysis and performance information, software documents,
     and other technical, business, product, marketing and financial
     information, plans and data, and any documents derived therefrom. The
     Software and all Ensemble software shall be deemed Confidential
     Information.

  b. Notwithstanding the foregoing, Confidential Information shall not
     include information that:
<PAGE>

     i.   is or subsequently becomes public without breach of this Agreement by
          the Receiving Party, its officers, directors, employees or agents;

     ii.  was previously in the Receiving Party's possession (in written or
          other recorded form) with no obligation to maintain confidentiality;

     iii. was received from a third party not under any obligation of
          confidentiality to the Disclosing Party; or

     iv.  was developed by the Receiving Party's employees, agents, contractors,
          and/or representatives independently of, and without reference to, any
          Confidential Information.

  c. The Receiving Party acknowledges that all Confidential Information is the
     exclusive property and trade secrets of the Disclosing Party or its owner
     as appropriate. The Receiving Party agrees not to use or disclose any
     Confidential Information in any manner adverse to the best interests of the
     Disclosing Party or contrary to the Disclosing Party's express
     instructions, and to discontinue all use of Confidential Information
     immediately upon the expiration or termination of this Agreement for any
     reason. The Receiving Party further agrees that its right to use
     Confidential Information is limited solely to the use thereof in connection
     with this Agreement. OEM shall also advise all of its employees, officers,
     directors, agents and sales representatives of the obligations herein and
     shall ensure such parties compliance with these requirements.

  d. The Receiving Party shall provide the Disclosing Party with written notice
     within ten (10) days of any known loss, theft, piracy or unintended or
     unauthorized disclosure of any Confidential Information.

  e. The foregoing confidentiality requirements shall survive the termination or
     expiration of this Agreement, and shall continue for a period of seven (7)
     years thereafter, provided, however Confidential Information considered a
     trade secret shall be maintained in a confidential manner for as long as
     such Confidential Information is considered a trade secret. The Receiving
     Party agrees and acknowledges that a breach of this confidentiality and
     non-disclosure obligation will likely result in irreparable harm to the
     Disclosing Party for which no adequate remedy at law exists. In such case,
     the Receiving Party agrees that the Disclosing Party shall be entitled to
     seek immediate injunctive relief from an appropriate court.

                                                                         Page 10
<PAGE>

     elements in interfaces and data storage permit specifying century to
     eliminate date ambiguity; and that for any date element represented without
     century, the correct century is unambiguous for all manipulations involving
     that element. Notwithstanding the foregoing, OEM acknowledges and agrees
     that (a) the Software does not identify or remedy Year 2000 problems in
     third party operating systems or other applications not supplied by Kana
     and (ii) the Software operates with the date information it receives; thus,
     if incorrect date information is provided by the user, the operating system
     or from any other external product or other source, this information will
     be used by the Software as received. The foregoing Year 2000 Compliance
     Warranty shall not apply to Year 2000 problems caused by such external
     sources. Notwithstanding any other provision herein, in any action to
     recover damages resulting directly or indirectly from a computer date
     failure, including any action based on an alleged computer date failure,
     the damages that may be recovered by OEM shall be limited to the extent
     those damages are incurred as a proximate and direct result of Kana's
     noncompliance or such Software's failure.

  d. Warranty Tracking.  It is OEM's obligation to maintain sufficient
     -----------------
     documentation and records to track Software warranties for its Customers.
     Kana assumes no responsibility to monitor or inform OEM of the tracking or
     expiration of applicable warranties for Software sold or licensed by OEM;
     such responsibility is solely that of OEM.

  e. Exclusions From Warranties.  KANA DOES NOT WARRANT THAT THE OPERATION OF
     --------------------------
     ANY PRODUCT WILL BE UNINTERRUPTED OR ERROR-FREE. THE LIMITED WARRANTIES
     PROVIDED HEREIN ARE NON-TRANSFERABLE, EXCEPT TO END-CUSTOMERS THAT HAVE
     PROPERLY LICENSED THE SOFTWARE AND ONLY FOR THE WARRANTY PERIOD AS MEASURED
     FROM THE ORDER DATE BY OEM FROM KANA, CONTINGENT UPON THE PROPER
     INSTALLATION AND USE OF THE RESPECTIVE PRODUCT IN ACCORDANCE WITH KANA'S
     SPECIFICATIONS, AND SUBJECT TO ALL LIMITATIONS AND RESTRICTIONS SET FORTH
     HEREIN. THESE WARRANTIES DO NOT APPLY TO ANY PRODUCT THAT (i) IS IN AN
     OPERATING ENVIRONMENT THAT DOES NOT COMPLY WITH KANA'S SPECIFICATIONS; (ii)
     HAS BEEN REPAIRED OR MODIFIED BY PERSONS OTHER THAN KANA OR ITS AUTHORIZED
     TECHNICIANS (WHICH SHALL INCLUDE DAVOX EMPLOYEES WHO HAVE OBTAINED KANA
     QUALIFICATIONS HEREUNDER); OR (iii) HAS BEEN DAMAGED OR RENDERED
     UNSERVICEABLE BY IMPROPER MAINTENANCE, ABUSE OR NEGLIGENCE ON THE PART OF
     PARTIES, OTHER THAN KANA.

  f. Limited Remedies Under Warranties.  Subject to the restrictions and
     ---------------------------------
     limitations contained herein, and within the applicable warranty period,
     Kana shall, free of charge, at its sole option, promptly repair or replace
     defective or nonconforming Software or components thereof; provided
     however, that Kana is notified in writing or by electronic mail of the
     defect or nonconformity within the applicable warranty period. Kana's
     response levels under its warranty obligations will be the same as Kana's
     support obligations as described in Exhibit B. All replaced Software or
     components thereof shall become Kana's property. THIS LIMITED REMEDY
     CONSTITUTES OEM'S SOLE AND EXCLUSIVE REMEDY UNDER THE LIMITED WARRANTIES.

  g. Disclaimer of Other Warranties.   THE EXPRESS WARRANTIES SET FORTH
     ------------------------------
     HEREIN ARE IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
     WITHOUT LIMITATION THE IMPLIED WARRANTIES OF TITLE, MERCHANTABILITY AND
     FITNESS FOR A PARTICULAR PURPOSE, WHICH ARE HEREBY SPECIFICALLY DISCLAIMED.

                                                                         Page 11

17.  LIMITATIONS OF LIABILITY\REMEDIES

  a. OEM AND CUSTOMER'S SOLE REMEDIES FOR KANA'S NONPERFORMANCE OR OTHER
     LIABILITY OF ANY KIND ARISING HEREUNDER, WHETHER IN CONTRACT OR IN TORT,
     ARE LIMITED TO THE EXPRESS REMEDIES PROVIDED HEREIN. EXCEPT AS PROVIDED
     UNDER SECTION 14 AND OTHER THAN FOR BREACHES OF SECTION 15, IN NO EVENT
     WILL EITHER PARTY'S LIABILITY TO THE OTHER OR TO ANY END-CUSTOMER FOR
     DAMAGES OF ANY NATURE, WHETHER ARISING UNDER A THEORY OF CONTRACT, TORT,
     STRICT LIABILITY OR OTHERWISE, EXCEED IN THE AGGREGATE THE TOTAL AMOUNTS
     PAID BY OEM HEREUNDER.

  b. EXCEPT AS PROVIDED FOR BREACHES OF SECTION 15, NEITHER PARTY WILL BE LIABLE
     FOR ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OR FOR ANY
     LOSS OF PROFIT, REVENUE, SOFTWARE OR DATA, COMPUTER VIRUSES AND TOLL FRAUD
     EVEN IF THE OTHER PARTY SHALL HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH
     POTENTIAL LOSS OR DAMAGE.

  c. BOTH PARTIES ACKNOWLEDGE THAT THE PRICES CHARGED TO HEREIN CONTEMPLATE THE
     FOREGOING ALLOCATION OF RISKS. EACH PARTY IS SOLELY RESPONSIBLE FOR THE
     PROTECTION AND BACK-UP OF ALL ITS -SUPPLIED DATA AND SOFTWARE USED IN
     CONJUNCTION WITH THIS AGREEMENT.

18.  SOURCE CODE ESCROW. During the term of this Agreement, Kana shall add OEM
as a beneficiary to Kana's source code escrow agreement. Kana grants to OEM a
limited, nonexclusive, nontransferable, nonsublicensable internal-use-only
license to the source materials for the Software, to allow OEM to maintain,
correct errors, support its use of the Software and continue exercising the
license under the terms of this Agreement (but not to otherwise modify or create
derivative works of the Software) upon the occurrence of the following release
conditions

  a. Kana materially breaches its Maintenance and Support obligations set forth
     in Exhibit B or its warranty obligation to OEM under Section 16(e); and

     i.   OEM provides to Kana written notice of the material breach and of
          OEM's intent to exercise this Source Code Escrow right; and

     ii.  for a period of at ninety (90) days after Kana's receipt of the
          foregoing written notice, Kana is unwilling or simply refuses to
          provide support services in material breach of Kana's maintenance and
          support obligations set forth on Exhibit B; and

     iii. provided that this subpart (a) shall not apply in the case where Kana
          is using its best commercially reasonable efforts to resolve the
          material breach; or

     iv.  Kana makes an assignment for the benefit of creditors, seeks
          protection under any bankruptcy, receivership or comparable
          proceeding, or if any such proceeding is instituted against Kana (and
          not dismissed within ninety (90) days).

19.  MISCELLANEOUS PROVISIONS

  a. Governing Law and Forum Selection.  This Agreement shall be construed
     ---------------------------------
     and enforced in accordance with the laws of the State of Illinois United
     States of America and all disputes hereunder shall be resolved in the
     courts governing, Chicago, Illinois and the parties consent
<PAGE>

     to jurisdiction therein. The United Nations Convention on Contracts for the
     International Sale of Goods shall not apply to this Agreement.

  b. Injunctive Relief. The parties acknowledge and agree that due to the
     -----------------
     unique nature of the Software, the Bundled Product and the parties'
     Confidential and Proprietary Information, there can be no adequate remedy
     at law for any breach of the confidentiality obligations hereunder and
     OEM's obligations with respect to the Software, and that any such breach
     may allow third parties to unfairly compete with the parties hereto
     resulting in irreparable harm and, therefore, that upon any such breach or
     threat thereof, the non-breaching party shall be entitled to seek an
     injunction and any other appropriate equitable relief, in addition to
     whatever remedies it may have at law.

  c. Non-Solicitation. During the term of this Agreement, neither party shall
     ----------------
     directly solicit to hire any employee of the other except with the prior
     written consent of the other; provided, however, that neither party shall
     be prevented from (i) soliciting to hire employees through classified
     advertising or (ii) hiring any employee of the other party so long as such
     hiring was not initially solicited, directly, by the hiring party. General
     advertisements shall not be deemed "solicitation" hereunder.

  d. No Assignment.  The rights and obligations of the parties hereunder
     -------------
     shall neither be assigned, subcontracted, delegated or otherwise
     transferred without the prior written consent of Kana. Otherwise, this
     Agreement shall be binding upon and shall inure to the benefit of the
     parties hereto and their respective successors and assigns. An assignment
     as permitted herein shall not diminish any rights or duties that either
     party may have prior to the effective date of assignment. Notwithstanding
     the foregoing, OEM may assign this Agreement to any successor, whether
     direct or indirect, who is not, in Kana's reasonable opinion, a competitor
     of Kana, by way of purchase, merger, consolidation or otherwise to all or
     substantially all of the business or assets of OEM, provided that OEM
     provides Kana with reasonable prior written notice.

  e. Force Majeure. Neither party shall be considered in default due to any
     -------------
     delay or failure in performance hereunder based on fire, strike, embargo,
     requirement of governmental, civil or military authority, act of God or the
     public enemy, failure of suppliers, or other causes beyond the reasonable
     control of Kana or OEM. When the delaying cause ceases, performance will
     resume, subject to an equitable schedule adjustment if necessary. If the
     delaying cause continues for more than sixty (60) days, the party injured
     by the other's inability to perform may by written notice cancel the
     affected purchase order or part thereof as to the Software not already
     delivered or service not performed.

  f. Compliance With Laws.  Each party shall comply with all federal, state
     --------------------
     and local laws and regulations which may be applicable, including without
     limitation, those applying to employers, the procurement of permits, export
     documents, licenses or certificates where needed, and those applying to
     packing, labeling and shipping, whether the shipment or services are
     interstate, intrastate or outside of the continental United States. Each
     party shall bear all costs associated with its compliance with laws,
     including but not limited to procurement of permits, licenses or
     certificates. OEM agrees that Kana Software will not be shipped into a
     restricted country as defined under the United States Export Regulation,
     Part 740.3 (d) and 772, as amended. Each party (the "Indemnifying Party")
     agrees to indemnify, hold harmless and defend the other party from and for
     any loss, damage, liability, claim or demand, fines or penalties, including
     costs, expenses and reasonable attorneys' fees, claimed or assessed against
     such other party or that may be sustained by such other party by reason of
     the Indemnifying Party's failure to comply with this Section.

     Agreement shall be of no force or effect until executed by both parties.

  j. No Implied Waivers.  The failure of either party at any time to require
     ------------------
     performance by the other party of any provision hereof shall not affect in
     any way the full rights to require such performance at any time thereafter
     unless such waiver is in writing. The waiver by either party of a breach of
     any provision hereof shall not be taken, construed, or held to be a waiver
     of the provision itself or a waiver of any breach thereafter or any other
     provision hereof unless specifically stated in writing.

  k. Captions and Section Headings.  Captions and section headings used herein
     -----------------------------
     are for convenience only, are not a party of this Agreement, and shall not
     be used in construing it.

  l. Severability.  A judicial determination that any provision of this

     they have the requisite and full authority to do so in the designated
     capacity.

     -------------------------
     parties warrant and represent that they are not bound by any other
     agreements, restrictions or obligations, contractual or otherwise, nor will
     either party enter into or assume any contract, restriction or obligation,
     which would directly breach the provisions of this Agreement.

  o. Relationship of the Parties.  Kana and OEM are acting solely as licensor
     ---------------------------
     and OEM, respectively. All sublicenses of Software by OEM shall be for
     OEM's own account as a principal and not as an agent of Kana. OEM shall act
     in all respects as an independent contractor and not as a legal
     representative or agent of Kana. This Agreement shall not be construed to
     create a relationship of partners, joint venturers, brokers, employees,
     agents, master or servant between the parties. Neither party shall have the
     right or authority to assume or create any responsibility, expressed or
     implied, in the name of the other or to bind the other in any manner or
     thing whatsoever.

                                                                         Page 14

     --------
     nature would survive, including without limitation the obligations
     contained in Sections 1, 4, 10, 11, 12, 15, 17 and 19 herein, shall be
     deemed to survive the cancellation, termination or expiration of this
     Agreement.

     ----------------
     the parties hereto pertaining to the subject matter hereof, superseding any
     and all previous proposals, representations or statement, oral or written.
     Any previous agreement between the parties pertaining to the subject matter
     of this Agreement are hereby expressly canceled and terminated. The terms
     and conditions of each party's purchase orders, invoices,
     acknowledgments/confirmations or similar documentation shall not apply to
     any order hereunder, and any such terms and conditions thereon shall be
     deemed to be objected to without the need of further notice or objection.

     To the extent OEM has not ordered the Minimum Commitment amount as of the
respective Due Date, then effective on such Due Date, OEM shall be deemed to
have ordered on a non-refundable basis Software in an amount equal to the
difference between the amount actually ordered by OEM and the Minimum Commitment
as of that date (the "Minimum Difference Order"). OEM shall be deemed to have
ordered such Software reflected in the Minimum Difference Order, and may
immediately or any time thereafter (even after termination of this Agreement),
draw-down such Software from the Master Copy. In order to draw-down such
Software, OEM shall request from Kana a license key to use the Software. The
draw-down for each such key shall be calculated based on the appropriate price
for such Software as determined by this Schedule A. Kana may immediately after
the Due Date invoice OEM for such Minimum Difference Order, regardless of
whether OEM actually draws-down such Software.

4.  Upfront Training.  Kana agrees to offer a one-time upfront sales, support
    -----------------
and technical training course for up to a total of 20 OEM personnel (the
"Upfront Training").  OEM shall be required to take the Upfront Training in
groupings as reasonably determined by Kana, with the current expectation that
one (1) technical training session will be held at the principal offices of Kana
and one (1) sales/support training session will be held at the principal offices
of OEM.  Kana shall waive the course fees for the Upfront Training, provided
that OEM pays all out-of-pocket expenses of Kana.

9.  Initial Construction of Additional Premises and Renovation of Original
    ----------------------------------------------------------------------
    Premises
    --------

    A.  Base Building Work
        ------------------

    Landlord will construct the base building for the Additional Premises and
related site improvements (including the design and construction of the
parkingdeck) in accordance with the preliminary construction drawings/conceptual
plans, as further developed by Landlord, and the outline specifications dated
December 22, 1997, revised August 24, 1999, October 25, 1999 and December 16,
1999 (collectively, the "Landlord's Plans").  A schedule of Landlord's Plans is
attached hereto as Exhibit A-1 (all of such work set forth in the Landlord's
Plans shall hereinafter be collectively referred to as the "Base Building
Work").

    Any changes, alterations or additions to the Base Building Work as
requested by Tenant may result in additional cost to Tenant, however, such
additional cost shall be supported by written documentation provided to Tenant,
as hereinafter provided.

    B.  Tenant Improvements to Additional Premises and Tenant Improvements to
        ---------------------------------------------------------------------
        Original Premises
        -----------------

    Tenant further acknowledges that Landlord shall construct additional tenant
improvements over and above the Base Building Work (the "Expansion Tenant
Improvements") in the Additional Premises, and additional tenant improvements to
the Original Premises (the "Existing Tenant Improvements") as more particularly
set forth in Section 9 (C) below, in accordance with a set of specifications to
be prepared by Tenant and a complete set of construction drawings for the
Expansion Tenant Improvements and the Existing Tenant Improvements (collectively
hereinafter referred to at times as the "Building Upgrades") to be prepared by
Tenant, as hereinafter provided, subject to final approval by Landlord and
Tenant (collectively, the "Tenant's Plans").  Landlord and Tenant hereby
acknowledge and agree that Tenant shall select an architect and/or an engineer
approved by Landlord in advance, which such approval shall not be unreasonably
withheld or delayed (collectively, "Tenant's Architect") for preparation of
Tenant's Plans, and the costs of services of such Tenant's Architect shall be
borne solely by Tenant, Landlord hereby agreeing, however, that it shall, in
connection therewith, provide in-house space planning and design services to
Tenant at no cost to Tenant.  Landlord and Tenant hereby further agree that
Tenant shall be solely responsible for coordinating with Tenant's Architect for
the timely preparation of Tenant's Plans in accordance with the terms and
provisions of this Lease.  Tenant shall have until May 15, 2000 to deliver to
Landlord the Tenant's Plans.  Landlord and Tenant shall use reasonable efforts
to reach agreement on the Tenant's Plans by May 31, 2000.  In reaching such
agreement, Landlord and Tenant shall approve portions of the Tenant's Plans that
are in acceptable form and shall note their respective objections to the
portions that are unacceptable to each of them.  If final agreement on the
Tenant's Plans is not reached by June 9, 2000, then Landlord and Tenant shall
attempt to mutually agree on an acceptable extension of time to complete the
Building Upgrades and the parties shall continue to use reasonable efforts to
reach agreement as soon as possible thereafter.
<PAGE>

Revisions to the Tenant's Plans shall be made expeditiously by Tenant's
Architect and shall be reviewed promptly by Landlord for approval.
Notwithstanding the foregoing, however, Landlord and Tenant hereby further agree
that all portions of the Tenant's Plans that may affect the Base Building Work,
including without limitation the slabs/underground utilities, roof, perimeter
walls, structural steel and foundations, must be delivered to Landlord by Tenant
on or before January 31, 2000 and approved by the parties promptly thereafter.

     Landlord will not approve construction drawings which involve any
construction, alterations or additions requiring unusual expense to readapt the
Additional Premises or the Original Premises to general office, light
manufacturing and assembly and other Permitted Uses on the Term Expiration Date,
unless Tenant first gives assurances acceptable to Landlord that such
readaptation will be made prior to such termination without expense to Landlord.
Landlord and Tenant hereby further agree to acknowledge in writing when final-
approval by Landlord and Tenant of the Tenant's Plans has occurred.

     Landlord shall have fifteen (15) days after final approval on Tenant's
Plans, which such final approval has been acknowledged in writing as aforesaid,
to price the cost of the Building Upgrades in accordance with Section 9 (C)
below.

     Landlord and Tenant shall cooperate during the above time periods so that
each party makes the other aware of their progress with respect to the foregoing
plans, selections and pricing, as well as timing, availability or cost
constraints of Tenant's selections or specifications and proposed alternates.

     Landlord shall cause the Additional Premises and Existing Tenant
Improvements to be completed in accordance with Landlord's Plans and Tenant's
Plans, all of such work to be performed by Landlord's general contractor,
Gutierrez Construction Co., Inc.  The Tenant may request changes to the Base
Building Work (or the Building Upgrades after final approval of the Tenant's
Plans by Landlord and Tenant) by altering, adding to, or deducting from the Base
Building Work or the Building Upgrades (as applicable) as set forth in
Landlord's Plans or approved Tenant's Plans, subject to Landlord's prior written
approval (each such requested change shall be submitted in accordance with the
form of Work Change Order attached hereto as Exhibit F).

     A change in Base Building Work initiated by the Tenant in writing (or in
the Building Upgrades as aforesaid which affects the Base Building Work) may
also necessitate an adjustment in the Scheduled Term Commencement Date(s).
Landlord agrees to provide Tenant with written notice, within five (5) days from
Tenant's suggested change, if any such adjustment in the Scheduled Term
Commencement Date(s) will be necessary based upon the change in the Base
Building Work (or the Building Upgrades, as applicable) initiated by Tenant.  In
addition, Landlord agrees to provide Tenant, upon Tenants' request, with
sufficient itemization and backup documentation to facilitate analysis and to
confirm the cost of any such changes in the Building Upgrades initiated by
Tenant.

     In addition, Tenant shall pay any additional amount equal to the Actual
Cost (as defined herein) of any increases to the total cost of the Base Building
Work due to such changes,
<PAGE>

including the costs of any changes from the outline specifications comprising of
a portion of the Landlord's Plans, plus a cost for overhead and general
conditions of seven percent (7%) of such cost and a Landlord's contractor's fee
of six percent (6%) of such cost, less appropriate credits for any Base Building
Work deleted (hereinafter referred to as the "Net Additional Cost of Base
Building Work"). The Net Additional Cost of Base Building Work shall be due and
payable to Landlord in the manner specified in Section 9 (C) below.

     In addition, Landlord will also disapprove any changes, alterations or
additions requested by Tenant which will unreasonably delay completion of the
Base Building Work or Building Upgrades due to materials or equipment having
long delivery times or which would cause construction sequencing delays, unless
Tenant agrees that the Scheduled Term Commencement Date(s) will be extended
accordingly, by such alterations or additions, giving due consideration to
Landlord's obligation to use reasonable efforts to accelerate construction to
make up for lost time due to delays.  Landlord agrees to promptly, not to exceed
five (5) days, provide Tenant with written notice of any such delays resulting
in the extension of the Scheduled Term Commencement Date(s).

     All Tenant improvements, changes and additions (except for Tenant's
business fixtures, equipment and personal property, including without
limitation, demountable partitions, manufacturing equipment, telephone or
computer systems, which such fixtures, equipment and personal property shall
remain the property of Tenant and shall be removed at the expiration of the
Term) shall be part of the Premises (and shall remain therein at the end of the
Term); and such other items shall be removed or left as the Landlord and Tenant
agree in writing prior to the installation thereof.  Tenant agrees to repair, at
its sole cost and expense, any damage to the Premises caused by any such removal
in accordance with this paragraph, unless caused by Landlord or its
representatives.

     C.  Net Additional Cost of Base Building Work and Building Upgrades
         ---------------------------------------------------------------
         Payments
         --------

     So long as Landlord has approved Tenant's Plans in writing, as hereinabove
set forth, Landlord and Tenant agree that Landlord's general contractor will
construct the Building Upgrades as aforesaid at cost (as hereinafter defined)
plus a fee for overhead and supervision of seven percent (7%) of such cost, plus
a general contractor's fee of six percent (6%) of such cost, less an allowance
equal to $5.50 per square foot applicable to the cost of the Existing Tenant
Improvements (the "Tenant Improvement Allowance").

     In order to provide for payment by Tenant of the cost of the Building
Upgrades, and any Work Change Orders provided for hereunder, including but not
limited to, the Net Additional Cost of Base Building Work, less the Tenant
Improvement Allowance as aforesaid, Tenant shall advance to Landlord, or its
contractor, as the case may be, within fifteen (15) days of receipt (plus such
additional time if Landlord submits the same to Tenant prior to the tenth (10th)
of each month as hereinafter provided, however in no event shall Tenant be
obligated to advance such funds earlier than the twenty-fifth (25th) of each
month) of each of Landlord's monthly requisitions therefor, the total amount of
any such requisition (collectively, "Tenant's Payments").  Landlord agrees that
it shall use reasonable efforts to submit such monthly requisitions to Tenant
prior to the tenth (10th) of each month (the anticipated date of submission
<PAGE>

of the same to Tenant), if possible, so that Tenant may have such additional
time upon receipt to advance funds to Landlord hereunder. Each construction
requisition submitted by Landlord in connection with the Building Upgrades only
shall include copies of all subcontractors' and suppliers' applications for
payment and satisfactory evidence of payment of all previous invoices submitted
by subcontractors and suppliers, except for applicable retention being withheld
in accordance with the terms of such obligations, and except for holdbacks
disclosed in writing for deficient work or disputed items. In addition,
Landlord's architect shall certify that the subject work specified in each of
such monthly requisitions has been substantially completed, and a copy of such
certification shall accompany each requisition furnished to Tenant hereunder. In
no event shall any of such costs due and payable hereunder relating to the
Additional Premises and relating to the Existing Tenant Improvements remain
unpaid by Tenant as of the Term Commencement Date for the Additional Premises
(as hereinafter defined in Section 9.2), and on such date which is thirty (30)
days after Substantial Completion of the Existing Tenant Improvements.

     Failure by Tenant to timely pay to Landlord the monthly amounts as herein
provided in this Article IX shall constitute a default by Tenant under this
Lease, provided that Landlord has given written notice to Tenant and Tenant
thereafter fails to cure such default within the applicable cure periods as
specified in Article XIX of the Lease.  Any late payments due by Tenant to
Landlord hereunder, which continue for a period of more than five (5) days from
the date thereof, shall commence to accrue interest at a rate equal to two
percent (2%) per annum in excess of the then prime rate of interest being
charged by Fleet National Bank, or its successor, otherwise if non-existent by a
majority of the national banks in Boston.

     For purposes hereof, the Net Additional Cost of Base Building Work, and the
total cost of the Building Upgrades performed by the Landlord's contractor,
shall be the Actual Cost of any of such work performed by Landlord, or
Landlord's contractor, as specified herein, less the Tenant Improvement
Allowance as aforesaid, as modified by approved Work Change Orders as aforesaid.
Landlord and Tenant further agree that the certification of cost by Gutierrez
Construction Co., Inc. shall be based on the definition of cost, as more
particularly set forth in Exhibit G hereto (the "Actual Cost").  Any changes to
the Tenant's Plans after the approval of the Tenant's Plans and any changes to
Landlord's Plans shall be in accordance with said form of Work Change Order
attached hereto as Exhibit F.  Landlord shall provide Tenant with construction
cost estimates based on Tenant's Plans, including a breakdown thereof (if
available), the name of the subcontractor, if available, and the work and/or
materials to be provided.  Unless otherwise mutually agreed upon by Landlord and
Tenant, in the pricing of the cost of the Building Upgrades, Landlord agrees to
obtain three (3) bids from qualified subcontractors selected from a master list
of subcontractors mutually prepared by Landlord and Tenant prior to the
soliciting of bids for the Building Upgrades, but only to the extent that a
particular item exceeds five thousand dollars ($5,000.00).  Giving due
consideration to factors such as price and delivery commitments and to
Landlord's construction experience, Landlord shall have the right to select
which such subcontractor shall be awarded the work for the Building Upgrades.
Upon Tenant's request, Landlord hereby agrees to furnish Tenant, within five (5)
days of such request, with copies of such subcontractor bids used by Landlord in
connection with the pricing of the Building Upgrades.  In addition, in the event
that Landlord and Tenant are unable to agree on the cost of any portion of said
work, Landlord's Construction
<PAGE>

Representative(s) and Tenant's Construction Representative(s), as set forth in
Section 9.4 below, shall, within ten (10) days of their inability to agree on a
price, select a third party familiar with building construction who shall
establish within ten (10) days of his selection the cost of the portions of the
work in dispute determined as set forth above. Said third party shall be
mutually chosen by Landlord and Tenant. The cost determined by said third party
shall be final and binding on Landlord and Tenant, and Landlord and Tenant shall
share equally the cost of such third party.

     Upon commencement of the Building Upgrades, Landlord and Tenant hereby
further agree, each acting reasonably and in good faith, to attend and
participate in construction meetings (weekly if necessary) with Landlord's
general contractor's construction manager(s) during such construction process.

     D.  Tenant's Construction Work
         --------------------------

     Tenant agrees that any construction included in Tenant's Plans which Tenant
specifies to be done by itself or its contractors, if applicable (hereinafter
referred to as "Tenant's Construction Work"), which may include equipment, and
Tenant's installation of furnishings and furniture and later changes or
additions, shall be coordinated with any work being performed by Landlord in
such a manner as to maintain harmonious labor relations and not damage the
Premises (including the Additional Premises being constructed hereunder), the
Building or Lot or interfere with the operation of the Building or with any of
Landlord's construction work hereunder, including but not limited to, the
construction of the Base Building Work and Building Upgrades.  It is hereunder
agreed and understood by and between Landlord and Tenant that Landlord's general
contractor shall construct the Base Building Work and Building Upgrades only and
that a contractor of Tenant's own choosing shall construct Tenant's Construction
Work as herein provided.  In no event shall Tenant be obligated to select
Landlord's general contractor for construction of the Tenant's Construction Work
hereunder.  Tenant (including its contractors, agents or employees) shall have
access to the Additional Premises and may perform Tenant's Construction Work on
the Additional Premises prior to or after the Scheduled Term Commencement Date
for the Additional Premises and to prepare the Additional Premises for occupancy
by Tenant provided that (i) Tenant's contractors, agents or employees work in a
harmonious labor relationship with Landlord's general contractor, (ii) prior
advance notice is given to Landlord's general contractor specifying the work to
be done (iii) no work shall be done or fixtures or equipment installed by Tenant
in such manner as unreasonably to interfere with any work being done by or for
Landlord on the Additional Premises, and (iv) Tenant has obtained, at its sole
cost and expense, any and all permits and approvals necessary in connection with
such work, if any.  During the period of any such preoccupancy of the Additional
Premises by Tenant in connection with Tenant's Construction Work prior to the
Scheduled Term Commencement Date for the Additional Premises such preoccupancy
shall be subject to all the terms, covenants and conditions contained in this
Lease.

9.2  Preparation of Premises for Occupancy
     -------------------------------------

     Landlord is obligated to perform the construction work set forth in the
Landlord's Plans and the Tenant's Plans, and therefore, Landlord agrees to have
the Additional Premises (which
<PAGE>

such term refers to the Base Building Work and the Expansion Tenant
Improvements) and the Existing Tenant Improvements (i.e. the Base Building Work
and the Building Upgrades) ready for occupancy by November 15, 2000 (the
"Scheduled Term Commencement Date for the Additional Premises") and within four
(4) weeks after such portion of the Original Premises that is being renovated is
vacated by Tenant (i.e. on a phase by phase basis) (the "Scheduled Term
Commencement Date for the Existing Tenant Improvements'), as such date(s) may be
extended hereunder for a period equal to that of (i) any delays due to Force
Majeure as defined in Section 9.5 hereof, and (ii) the number of days of delay
caused by Tenant including without limitation days of delay due to Work Change
Orders initiated by Tenant as aforesaid.

     Landlord and Tenant agree that time is of the essence, and Landlord agrees
to use reasonable efforts to accelerate construction to make up for time lost
due to any delays.

     The Term of this Lease with respect to the Additional Premises shall
commence on the date the Additional Premises (which such term refers to the
Base Building Work and the Expansion Tenant Improvements as aforesaid) are
deemed ready for occupancy as set forth below (the "Terra Commencement Date for
the Additional Premises").

     The Additional Premises shall be deemed ready for occupancy on the earlier
of:

     (a) the date on which the Tenant occupies all, or any portion of, the
Additional Premises and commences operations therein (expressly excluding,
however, any preoccupancy by Tenant for purposes of completing the Tenant's
Construction Work as set forth in Section 9 (D) above); or

     (b) the date on which the Additional Premises are Substantially Completed,
as defined below, as certified by Landlord's architect, and Landlord has
delivered to Tenant copies of all permits and approvals required to be obtained
from any governmental agency prior to occupancy of the Additional Premises by
Tenant, including, without limitation, a certificate of occupancy from the Town
of Westford or a temporary certificate of occupancy from the Town of Westford
which allows Tenant to use and occupy the Additional Premises and which
temporary certificate of occupancy is not conditional on the performance of any
work other than the Punch List Work as defined below, except that such permit(s)
and approval(s) shall not be required as a condition of Substantial Completion
if Landlord is unable to secure the same due solely to Tenant's failure to
complete Tenant's Construction Work as specified in Section 9 (D) above (which
such date, subject to additional terms and provisions of this Section, shall
hereinafter be referred to as the date of "Substantial Completion" or which such
work shall hereinafter be referred to as "Substantially Completed").

     An AIA Certificate of Substantial Completion by the Landlord's architect
(which such Certificate shall be in the form attached hereto as Exhibit H) shall
evidence the Landlord's determination that it has performed all such
obligations, except for completing the landscaping work and completing the
finish paving course, if applicable, and minor items stated in such Certificate
to be incomplete or not in conformity with such requirements, all of which work
will not unreasonably interfere with Tenant's use or occupancy of the Premises
and all of which work and shall be identified in the Certificate of Substantial
Completion (collectively such landscaping
<PAGE>

work, finish paving course work and minor items are referred to herein as the
"Punch List Work") shall be promptly completed. Tenant shall have the right
within fifteen (15) days after Tenant's receipt of such Certificate of
Substantial Completion to notify Landlord of any disagreement with said
Certificate and to identify additional items of Punch List Work, all of which
shall be completed by Landlord thirty (30) days after notice thereof by Tenant.
Landlord agrees to furnish to Tenant said Certificate of Substantial Completion,
regardless of whether Tenant is occupying the Additional Premises (or any
portion thereof) or not, upon performance of all of the obligations set forth
above.

     If weather interferes with Landlord's ability to finish the final course of
paving and outside work or such other Punch List Work which such work does not
substantially interfere with Tenant's occupancy, within thirty (30) days after
the date of Substantial Completion as herein provided, said work can be
completed by Landlord reasonably thereafter, so long as such delay does not and
will not interfere with or prevent Landlord from obtaining a certificate of
occupancy upon completion of all other work herein described.

     After Landlord has completed all Base Building Work and Building Upgrades,
including all Punch List Work, Landlord's architect shall forward to Tenant a
Certificate of Final Completion, such Certificate to be in the form attached
hereto as Exhibit I.  In addition, upon completion of all such work, including
all Tenant's Construction Work by Tenant, Landlord shall forward to Tenant a
final certificate of occupancy from the Town of Westford.

9.3. General Provisions Applicable to Construction
     ---------------------------------------------

     All construction work required or permitted by this Lease, whether by
Landlord or by Tenant (or by their respective subcontractors), shall be done in
a good and workmanlike manner, in compliance with this Agreement, and in
compliance with all applicable laws and all lawful ordinances, regulations and
orders of any governmental authority and insurers of the Building.  Either party
may inspect the work of the other at reasonable times and may give notice of
observed defects.  Notice of such defects shall be in writing and shall be
rectified by Landlord or by Tenant, as the case may be, within thirty (30) days
of the original date of the notice.  Failure to provide notice hereunder shall
not be the basis for any liability or for injury or damage caused by such defect
or waiver of right to cause any defect to be corrected.

9.4. Representatives
     ---------------

     Landlord hereby acknowledges and agrees that only the following persons, Ed
Cunniffe, Mark Albonesi or John J. Connolly or any successors to either of them
holding the same title or any other person delegated the authority from him in

matters requiring Tenant's action in this Article.  No consent, authorization or
other action by Tenant with respect to matters set forth in this Article shall
bind Tenant unless in writing and signed by one of the aforementioned persons.
Landlord hereby expressly recognizes and agrees that no other person claiming to
act on behalf of Tenant is authorized to do so.  If Landlord complies with any
request or direction presented to it by anyone claiming to act on behalf of
Tenant who does not have the title and position mentioned above, such compliance
<PAGE>

shall be at Landlord's sole risk and responsibility and shall not in any way
alter or diminish the obligations and requirements created and imposed by this
Article, and Tenant shall have the right to enforce compliance with this Article
without suffering any waiver or abrogation of any of its rights hereunder.

     Tenant hereby acknowledges and agrees that only the following persons:
Arturo J. Gutierrez, John A. Cataldo, Dennis G. Bailey, or P. Agustin Rios, or
any successors to either of them holding the same title or any other person
delegated the authority from either of them in writing (hereinafter "Landlord's
Construction Representatives") have the authority to act on Landlord's behalf
and represent Landlord's interests with respect to all matters requiring
Landlord's action in this Article.  No consent, authorization or other action by
Landlord with respect to matters set forth in this Article shall bind Landlord
unless in writing and signed by one of the aforementioned persons.  Tenant
hereby expressly recognizes and agrees that no other person claiming to act on
behalf of Landlord is authorized to do so.  If Tenant complies with any request
or direction presented to it by anyone claiming to act on behalf of Landlord who

and Landlord shall have the right to enforce compliance with this Article
without suffering any waiver or abrogation of any of its rights hereunder.

9.5. Force Majeure
     -------------

     As used in this Article and elsewhere in the Lease, "Force Majeure" shall
mean the definition set forth in Section 26.12 of this Lease.

9.6. Warranty
     --------

     The Base Building Work and Building Upgrades shall be warranted against
construction defects in materials and in workmanship for a period of one (1)
year from the date of Substantial Completion as determined pursuant to Section
9.2. only.  Upon the expiration of said one (1) year period, Landlord shall
assign to Tenant any and all warranties and guarantees (including without
limitation standard HVAC and roof warranties) with respect to the Base Building
Work and Building Upgrades, and to the extent that any of such warranties and
guarantees are not assignable, Landlord agrees to enforce the same for the
benefit of Tenant, at Tenant's expense; provided, however, that Tenant shall not
be responsible to pay for any such enforcement by Landlord against its own
employees or against Gutierrez Construction Co., Inc. or against any of its
other affiliates (including their respective employees)."

9.7. Arbitration by Architects
     -------------------------

     Whenever there is a disagreement between the parties with respect to
construction by Landlord of the Base Building Work or the Building Upgrades,
except as otherwise expressly set forth herein, such disagreement shall be
definitively determined by the following procedure: Each of Landlord and Tenant
shall appoint one (1) independent architect, such two (2) architects will then
(within five (5) days of their appointment) appoint a third independent
architect licensed in the Commonwealth of Massachusetts with not less than ten
(10) years experience.
<PAGE>

Each architect shall establish within ten (10) days of their appointment the
matter in dispute. In case of any dispute with respect to dollar amounts or
lengths of time or dates such as the date of Substantial Completion, the dollar
amount or length of time or date shall be the average of the two closest
determinations by the three (3) architects, with the determination of the
architect which was not closest to another architect's determination excluded
from such calculation. In case of any dispute not involving dollar amounts or
lengths of time or dates (i.e. the approval of plans) the determination by at
least two (2) of the three (3) architects shall be required in order to resolve
the matter in dispute. Landlord and Tenant shall each bear the cost of the
architect selected by them respectively and shall share equally the cost of the
third architect. During such arbitration period, the parties agree to cooperate
with one another so as to proceed with construction and with their respective
obligations hereunder in a timely manner. Each determination under this Section
9.7 shall be binding upon Landlord and Tenant."

     6.   Article XXVI, Section 26.10 of this Lease, is hereby amended by
deleting all previous language in its entirety and by replacing the same with
the following:

          "Tenant's occupancy of the Premises (which such term includes the
Additional Premises following the Term Commencement Date for the Additional
Premises) shall include the right to the exclusive use of 4.3 per 1,000 square
feet of space, as shown on Exhibit A-1."

     7.   Landlord and Tenant (each, a "representing party") each represents and
