Item 1: Business

The Company

      MDSI develops, markets, implements and supports mobile workforce
management solutions for use in the field service industry. The Company's
products include market-specific applications, wireless connectivity software
and related network and mobile computing equipment. These products are used
by a wide variety of companies with substantial mobile workforces, such as
utility, telecommunications companies, and public safety organizations. When
used in conjunction with public and private wireless data communications
networks, MDSI's products provide comprehensive solutions for the automation
of business processes associated with the scheduling, dispatching and
management of a mobile workforce. In addition, these products enable the
Company's customers to cost-effectively communicate with their mobile
workers, while simultaneously enabling the mobile workforce to interface with
their corporate information system on a real-time basis.

      The first generation of the Company's core product for the utility
market, Advantex-Utility, was originally developed by MDI Mobile Data
International Inc. ("MDI"), which was acquired by Motorola, Inc. ("Motorola")
in 1988. The Company's predecessor, MDSI Mobile Data Solutions Canada Inc.
("MDSI Canada"), commenced operations in February, 1993 when it acquired the
Advantex-Utility 4.0 and certain other assets of the Mobile Data Division of
Motorola Canada Limited, a wholly-owned subsidiary of Motorola.

      In December 1995, as part of its strategy to broaden its technology base
and product offerings, the Company, MDSI Canada and TelSoft Mobile Data Inc.
("TelSoft") completed a plan of arrangement (the "Plan of Arrangement") under
the Company Act (British Columbia). Pursuant to the Plan of Arrangement, the
Company was incorporated in September 1995 under the Canada Business
Corporations Act ("CBCA") as 3181910 Canada Inc. The Company changed its name to
MDSI Mobile Data Solutions Inc. in December 1995. Prior to the Plan of
Arrangement, TelSoft held a 60% interest in MDSI Canada. As part of the Plan of
Arrangement, the Company


                                       2
<PAGE>

acquired all of the outstanding shares of TelSoft in exchange for 1,828,387
Common Shares of the Company and the assumption of $797,000 principal amount of
convertible debentures (the "Convertible Debentures") previously issued by
TelSoft, and all of the outstanding shares of MDSI Canada, other than those
shares of MDSI Canada already owned by TelSoft, in exchange for 2,160,000 Common
Shares of the Company. Following the acquisition of TelSoft, TelSoft was merged
with and into MDSI Canada. The acquisition by the Company of MDSI Canada was
accounted for as a reorganization of assets under common control. Accordingly,
the Company is deemed to be a continuance of MDSI Canada subsequent to the Plan
of Arrangement, and the historical accounting basis of MDSI Canada was carried
forward. The acquisition of TelSoft has been accounted for under the purchase
method of accounting. Effective October 1, 1998, the Company carried out a
vertical short form amalgamation with MDSI Canada pursuant to which MDSI Canada
was amalgamated with and into the Company. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations - Effects of
Acquisitions".

      In June 1996, the Company acquired all of the outstanding share capital of
MDSI UK for aggregate consideration of $10,616,023, consisting of 55,263 Common
Shares and $9,733,270 ((pound)4,500,000) in cash. The acquisition of MDSI UK was
accounted for by the Company under the purchase method of accounting. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Effects of Acquisitions."

      In July 1997, the Company acquired all of the outstanding share capital of
Alliance Systems, Incorporated ("Alliance") for aggregate consideration of
$9,116,828, consisting of 347,750 Common Shares and US$1,582,088 ($2,188,750) in
cash. Effective January 4, 1999, Alliance merged with Mobile Data Solutions Inc.
("MDSI USA"), a Delaware corporation and a wholly-owned subsidiary of the
Company. MDSI USA is the surviving corporation. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations - Effects of
Acquisitions" and " Results of Operations - Effects of Acquisitions."

      In February 1999, the Company's Board of Directors approved a plan to
dispose of its transportation business unit. Effective June 1, 1999, the Company
completed the sale of the transportation business unit to Digital Dispatch
Systems, Inc. ("DDS"), a supplier of dispatch systems to the taxi market for
proceeds of $5,532,730. The proceeds were comprised of common shares of DDS,
representing an 11% interest in DDS, and a promissory note in the principal
amount of $500,000, due January 1, 2001, bearing interest at 8% per annum.

      Unless the context otherwise requires, references herein to "MDSI" or the
"Company" refer to MDSI Mobile Data Solutions Inc. and its subsidiaries. The
Company's principal executive offices are located at 10271 Shellbridge Way,
Richmond, British Columbia, Canada V6X 2W8, and its telephone number at that
location is (604) 207-6000.

Background

      Organizations within the field service industry are highly dependent upon
their mobile workforces to support their respective products and services. The
field service industry is composed of a number of market segments, such as the
utility, telecommunications, cable and other general field service repair
markets, in which mobile workers principally provide repair, maintenance,
installation and other services for customers. The public safety market is
composed of the police, fire and ambulance markets in which mobile workers
provide law enforcement, emergency and medical services. Historically, these
organizations have managed and supported their mobile workers by communicating
information through wireline or voice radio systems. Although voice radio
systems are mobile, such systems rely on heavily used portions of the radio
spectrum and are subject to frequent periods of congestion.

      Mobile data communication systems that addressed certain limitations of
voice communications systems were first developed for a limited number of
vertical markets, such as utility, public safety, taxi, courier and general
field service. Businesses in these markets recognized certain productivity
benefits associated with wireless data applications. Although such mobile data
communications systems were introduced in a number of vertical markets, these
systems failed to achieve widespread adoption. The Company believes that the low
rate of adoption was attributable to the high cost of establishing private radio
networks, the difficulty of obtaining radio spectrum for such networks, the high
cost and limited functionality of early mobile computing devices and the
regulatory environment in certain industries, such as utilities and
telecommunications, which diminished competitive pressures. Additionally, a lack
of industry-specific application software which effectively addressed the needs
of mobile workers limited the cost-effectiveness of early systems.

      The Company believes that significant trends in the regulatory
environment, numerous technological advances and a recent significant
increase in competitive pressures have reduced many of these limitations and
have accelerated, and will continue to accelerate, the adoption of mobile
data solutions by the field service industry. Deregulation has exposed the
utility and telecommunications markets to new competitive pressures, driving
businesses within those markets to seek ways to reduce costs, improve
operations, efficiently allocate resources and increase the quality of
customer service. In addition, the availability of powerful mobile computing
devices has permitted the development of sophisticated software applications.
Finally, public data networks, such as ARDIS and RAM, are now widely
available in North America, and similar networks are available in Europe and
the Asia Pacific region. Increasing competition among these networks and the
emergence of new wireless communication services, provided by organizations
such as AT&T, Ameritech Mobile Communication and others, has resulted in
greater availability of wireless networks and lower costs to

                                       3
<PAGE>

subscribers. Consequently, the Company believes that mobile data solutions may
now be implemented without the difficulty and expense of establishing a private
radio network, thereby increasing the cost-effectiveness of such systems. The
Company believes that the convergence of these trends will increase the
likelihood of adoption of mobile data solutions by companies in the field
service industry. See "Forward-Looking Statements."

The MDSI Solution

      MDSI has combined its expertise in software application development and
mobile data communications technology with its understanding of the unique
needs of targeted vertical markets in the field service industry to develop
mobile workforce management solutions that address the specific needs of
businesses within those vertical markets. MDSI's products enable
organizations in the field service and public safety industries to
effectively communicate with, manage and support their mobile workers.

      MDSI's solutions include the Advantex family of applications and
wireless connectivity software products designed for the field service
industry. MDSI's software products provide applications for the automation of
business processes, such as service order generation, scheduling and
assignment, as well as wireless applications, such as work order dispatch,
real-time status updates, service and credit authorization, two-way messaging
and remote database access. MDSI's products are combined with professional
services, such as implementation planning, project management, software
configuration, software customization, training and ongoing technical support
and software maintenance to effectively address a customer's mobile workforce
management requirements. Where appropriate, MDSI also provides third party
products and services as part of a complete mobile data solution. MDSI also
offers general consulting services to organizations evaluating the costs and
benefits of implementing mobile workforce management systems, as well as
organizations evaluating wireless industry software products and technologies.

      MDSI's products are scaleable to address the needs of both small and large
organizations. For example, MDSI's Advantex-Utility product has been sold for
applications intended to support as few as 70 and as many as 7,000 mobile
workers. MDSI's products are also modular so that a solution can be implemented
in phases and expanded to satisfy an organization's evolving information
requirements. MDSI's products are designed to interface with a variety of public
and private mobile data networks, including PCS networks and satellite-based
data transmission networks, and are compatible with a variety of operating
platforms, computer networks and in-house applications.

Markets

      The Company markets its products and services within the field service
industry. The Company evaluates new markets based upon their similarity to
existing vertical markets in which the Company has been successful, and upon
the ability of the Company to utilize its core competencies and proven
technology to meet the needs of companies in these new markets.

      The field service industry consists of organizations having significant
numbers of mobile workers who provide various customer services outside of the
office. The Company believes that increasing competition is forcing field
service companies to focus on the efficiency and quality of their customer
service operations. The Company's principal vertical markets within the field
service industry are the utility, telecommunications and cable markets. MDSI
also provides products for other segments of the field service industry, such as
companies engaged in the maintenance and repair of office equipment.

      Utilities. The utilities market targeted by the Company primarily consists
of gas and electric companies. Industry sources indicate that there are
approximately 4,100 gas and electric companies in the United States. The Company
has traditionally targeted the distribution operations within a utility. The
Company believes, however, that such operations generally account for only a
portion of the total number of a utility's mobile workers, with the balance
attributable to mobile workers engaged in sales, construction, engineering and
management functions. As a result, the Company believes that there is an
opportunity to increase sales to existing customers and generate incremental
revenue. See "Forward-Looking Statements". MDSI's products have been implemented
or are being implemented in over 60 gas and electric utilities located in the
United States, Canada, the United Kingdom and Asia.

      In the United States, the production and supply of natural gas and
electric power has been regulated primarily by the Federal Energy Regulatory
Commission (the "FERC"). In recent years, the FERC has implemented rules
designed to transfer certain areas of regulatory authority from the FERC to
state utility commissions and to encourage competition in the supply and
delivery of energy resources. As a result of these regulatory changes and other
anticipated regulatory developments, the Company believes that gas and electric
utilities are facing new competitive pressures and are seeking ways to reduce
costs and improve the quality of their customer service.

      Telecommunications. The telecommunications market consists of providers of
local, long-distance and wireless communication services worldwide. The Company
believes that this market will grow as companies implement new technology to
improve their


                                       4
<PAGE>

competitiveness, efficiency and service levels. See "Forward-Looking
Statements." The Company has installed or has a contract to supply its
products to numerous telecommunication companies worldwide, including two
divisions of AT&T, Tele Danmark A/S, Citizens Telecom Services Company L.L.C.
and Belgacom S.A.

      Cable. The cable market targeted by the Company consists of providers
of cable television services principally in North America and Europe. In
North America, over 75% of the subscriber base is under the control of the
ten largest multiple service operators. Changes in the regulatory environment
and technological developments, such as satellite television have led to the
introduction of significant competition in the cable market. Technological
advances have also led to the development of new services utilizing the cable
infrastructure, allowing cable operators to provide high-speed Internet
access and basic telephony to subscribers. The Company believes that growing
competition and the introduction of new services will lead cable operators to
adopt mobile data solutions to improve their competitiveness, efficiency and
level of customer service. See "Forward-Looking Statements." Although several
major cable operators have implemented mobile data solutions in selected
sites, few operators have rolled out these systems to multiple sites. The
Company has installed or has a contract to supply its products to seven major
cable operators, including Cox Communications Inc., Comcast Corp., MediaOne,
Inc., Cablevision Systems and Adelphia Communications Corporation in the
United States and Rogers Cablesystems Ltd. and Videotron in Canada.

      Public Safety. The public safety market consists of federal, state and
local agencies that provide police, fire, medical and other emergency services.
The public safety industry was one of the first vertical industries to adopt
mobile data technology. As a result, the Company believes that many
organizations in the public safety industry are now poised to upgrade their
original mobile data systems with new technology that provides increased
capabilities over the first generation systems. See "Forward Looking
Statements." The Company has installed one Advantex-Public Safety product with
the North Carolina State Highway Patrol and has a contract to supply this
product to the State of Ohio.

Customers and Applications

      The Company's customers vary in size from small local service companies to
large regional and international organizations. During the year ended December
31, 1999 one international telecommunication company, Beligacom S.A., accounted
for 12.2% of the Company's consolidated revenues, and for the years ended
December 31, 1998 and 1997, one U.S. utility company accounted for 9.1% and
14.4%, respectively, of the Company's consolidated revenue. In the years ended
December 31, 1999, 1998 and 1997, approximately 36.6%, 32.6% and 42.5%,
respectively, of the Company's consolidated revenue was attributable to five or
fewer customers. The Company believes that revenue derived from a limited number
of customers will continue to represent a significant portion of its
consolidated revenue. In the years ended December 31, 1999, 1998 and 1997,
revenue derived from sales outside of North America accounted for 24.8%, 3.4%
and 10.1% of the Company's total revenue, respectively. See "Note 12 of the
Company's Consolidated Financial Statements." Because the Company's revenue is
dependent, in large part, on significant contracts with a limited number of
customers, the percentage of the Company's revenues that is derived from sales
outside of North America has fluctuated, and may continue to fluctuate, from
period-to-period. See "Business-Risk Factors - Dependence on Large Contracts and
Concentration of Customers" and "Forward-Looking Statements."

Products

      The Company currently offers mobile workforce management solutions
focused on the field service industry. The Company's products automate
processes such as appointment scheduling, work load distribution, service
order dispatching, real-time status updating, credit card authorization and

the field service industry. Advantex-Field Service's core dispatch functionality
allows service calls to be entered, displayed, printed and updated. The dispatch
function allows work to be assigned, re-assigned, re-scheduled or canceled. A
summary of the service schedule can be displayed for any day or week. A
dispatcher has access to all customer information (by name, telephone number,
customer number or equipment identifier), including the ability to access terms
of agreements and view dispatch times, current field worker locations and
schedules.

      Advantex-Public Safety. The Advantex-Public Safety product is a mobile
data solution for the public safety market. The software provides connectivity
between statewide networks and databases and wireless networks. The solution
consists of a message switch and a mobile device software application. The

develop and recommend modifications to the customer's business processes to
improve the performance of the MDSI software and reduce or eliminate the need
for customization.

      During the final phase of implementation, MDSI personnel complete
configuration of the software products, complete project customization, finalize
product installation and develop end-user documentation and other technical and
business processes required to integrate the MDSI products into the client's
environment. MDSI personnel also work with the client to develop and test custom
features and various interfaces to corporate networks, wireless networks and
other corporate information systems.

Customer Support

      The Company believes that its ability to offer a high level of customer
support is critical to its success. The Company's customer support group
provides MDSI customers with telephone and on-line technical support as well as
product updates. Most MDSI customers enter into separate customer support
agreements, typically on an annual basis, that take effect on the expiration of
the product warranty. At December 31, 1999, the Company had 46 customer support
personnel, of whom 22 were located in Canada, 19 in the United States, 1 in the
United Kingdom and 4 in Copenhagen.

Product Development

      The mobile workforce management industry is characterized by rapid
technological change and increasing user requirements. Accordingly, the Company
must be able to provide new products and to modify and enhance existing products
on a timely and continuing basis in order to be competitive. To accomplish this
objective, the Company's strategy is to utilize proven technology to further
enhance its existing products and to create new products. Where appropriate, the
Company may acquire complementary technology developed by third parties for
integration into the Company's products.

      The Company believes that its highly qualified software development
personnel provide MDSI with a competitive advantage. MDSI personnel have
considerable experience and expertise in the development of mobile workforce
management applications specifically designed for use with a wireless data
network, as well as in the integration of these applications with a customer's
corporate information system. MDSI software product development personnel employ
modular software architecture, object-oriented software development and
graphical user interface design technologies to develop scaleable, modular,
configurable products. MDSI personnel have expertise in software technology,
wireless and wireline communications technologies, computer environments and
corporate information systems integration. They also have considerable expertise
in the design and development of specialized mobile computing devices, as well
as radio system design and implementation. MDSI believes that this combination
of expertise in multiple disciplines has allowed and will continue to allow the
Company to design and develop mobile workforce management solutions which can be
implemented in a timely and cost-effective manner.

      As of December 31, 1999, MDSI's technical and engineering staff,
supporting both product development and professional services, consisted of 286
employees, including 223 employees based at its Richmond, British Columbia
headquarters, 62 employees based primarily at its Itasca, Illinois facility and
other locations in the United States and 1 in the United Kingdom.

      During the years ended December 31, 1999, 1998 and 1997, the Company's
total expenditures for product development were $9.9 million, $8.7 million and
$4.9 million, respectively, reflecting 12.9%, 13.0% and 9.3% of the Company's
revenue, respectively. Management believes that timely and continuing product
development is critical to the Company's success and plans to continue to
allocate significant resources to product development. See "Forward-Looking
Statements."

Sales and Marketing

      The Company markets its products and services through its direct sales
force and certain strategic remarketing arrangements. The Company's sales
personnel, who are knowledgeable about the technological components of wireless
applications and current industry and enterprise-specific application issues,
work in teams that specialize in each of the targeted vertical markets. The
Company's sales personnel employ their expertise to develop long-term
consultative relationships with customers in order to identify the needs of the
customer and provide specific and effective solutions. To date, substantially
all of the Company's revenue has been generated by direct sales activities.

      On February 1, 2000, the Company announced that it intends to sell its
Advantex family of mobile workforce and wireless connectivity application
software products over the Internet. See "Subsequent Events."

      At December 31, 1999, the Company's sales, marketing and technical support
group consisted of 47 employees, with 26 based out of the Company's Richmond,
British Columbia facility, 18 based out of its Itasca, Illinois facility, and 3
based out of various other international locations.

Competition

      The markets for mobile workforce management applications, wireless
connectivity software, mobile data network equipment and mobile computing
devices are highly competitive. Numerous factors affect the Company's
competitive position, including price, product features, product performance and
reliability, ease of use, product scalability, product availability on multiple
platforms (both server and mobile workstation), ability to implement mobile
workforce management solutions domestically and internationally while meeting
customer schedules, integration of products with other enterprise solutions,
availability of project consulting services and timely ongoing customer service
and support.


                                       7
<PAGE>

      Within these markets, there are a small number of new ventures, either
small companies attempting to establish a business in this market or large
companies attempting to diversify their product offerings. The Company expects
such competition to intensify as acceptance and awareness of mobile data
communications and technology continue. In addition, a small number of the
Company's potential customers develop software solutions internally, thereby
eliminating the requirement for suppliers such as the Company. Current or
potential competitors may establish cooperative arrangements among themselves or
with third parties to increase the ability of their products to address customer
requirements.

      Certain of the Company's competitors have substantially greater financial,
technical, marketing and distribution resources than the Company. As a result,
they may be able to respond more quickly to new or emerging technologies and
changing customer requirements, or to devote greater resources to the
development and distribution of existing products. There can be no assurance
that the Company will be able to compete successfully against current or future
competitors or alliances of such competitors, or that competitive pressures
faced by the Company will not have a material adverse effect on its business,
financial condition, operating results and cash flows.

      The Company believes that in the utility and telecommunications industry
segments the most important competitive factors are the reputation of the
supplier and their proven record in implementing wireless data solutions. The
Company primarily competes in the utility market with Utility Partners, L.C.,
M3i Systems, Inc. and Alterra Corp. The Company has several competitors in the
telecommunications market, a few of which have historical relationships with
certain of the large telecommunications companies. The Company's primary
competitors for telecommunications customers are Lucent Technologies, Inc. and
Telcordia (formerly Bellcore).

      The Company believes that the principal competitive factors in the field
service market are the ability to improve the customer service aspects of an
organization's business and increase the productivity of service
representatives. In this market, the Company's principal competitors are Astea
International Inc. and Metrix Inc. The Company's principal competitors in the
cable market are Telcordia and MobileForce Technologies, Inc. (formerly
Ubiquinet, Inc).

      MDSI primarily competes in the public safety market with Cerulean, PRC,
Tiberon Systems, and New World Systems. Many of MDSI's competitors have a more
established reputation in the public safety market. In many of the large public
safety opportunities, MDSI is a subcontractor to a large prime contractor
serving as the overall system integrator. MDSI is currently used as a
subcontractor for public safety installations by Motorola.

Employees

      As of December 31, 1999, the Company had 453 full-time employees and
contractors, including 286 in technical and engineering, 47 in sales, marketing
and technical support, 46 in customer support and 74 in management, finance and
administration. None of the Company's employees is represented by a labor union
and the Company believes its employee relations to be good.

Subsequent Events

      On February 1, 2000, MDSI announced that it intends to sell its
Advantex family of mobile workforce management and wireless connectivity
application software products over the Internet from a wirelessly-enabled
Applications Service Provider ("ASP") site. When delivered over the Internet,
it is anticipated that the Advantex applications will be similar
in functionality to versions installed at customer sites. It is anticipated
that MDSI's customers will pay a monthly fee for use of the applications or
pay for the use of services on a "per transaction" basis. This strategy is
intended to create a recurring source of revenue for the Company.

      The Company believes that its eBusiness strategy will assist it in
addressing the needs of smaller organizations in its traditional markets that
were previously unable to afford its products, and who did not have the
technical resources to support such products. See "Forward-Looking
Statements." MDSI intends to offer its ASP solution to customers through
(i) direct sales by MDSI, and (ii) co-marketing and partnership
arrangements with other ASP providers in select vertical markets.

      MDSI also intends to use the ASP to host scheduling and dispatching
engines, which are limited-function, non-configurable versions of its
existing scheduling and wireless dispatching modules. MDSI intends to offer
these ASP-based products separately or jointly to small customers with simple
requirements in a variety of field service markets. See "Forward-Looking
Statements."

                                       8
<PAGE>

Markets (eBusiness)

      The Company intends to build upon its strength in the utilities and
telecommunications industries to implement the Company's eBusiness strategy.
The Company believes that competition and deregulation create an opportunity
for MDSI to offer its ASP services to smaller and medium-sized businesses in
MDSI's existing "core" markets. The Company's eBusiness offering is targeted
at the general services marketplace, which has been marked by the entrance of
Internet intermediaries who offer a wide range of services, including home
services, to consumers and small and medium-sized businesses. MDSI intends to
initially target the U.S. and Canadian markets and then pursue opportunities
in Europe. Further, MDSI intends to leverage its existing relationships with
wireless network carriers to act as an additional distribution point for its
ASP services. See "Forward-Looking Statements."

Customers and Applications (eBusiness)

      Currently, the Company does not have any eBusiness customers. The
Company, in discussion with two organizations to establish new marketing
channels. The Company is currently engaged in negotiations with OurHouse.com
Inc. ("OurHouse.com"), an Internet web site for home improvement, home
services and how-to information. The Company intends to enter into a
distribution agreement with OurHouse.com, under which the Company will
provide its scheduling and wireless dispatching engines to OurHouse.com.
Under the proposed distribution arrangement, OurHouse.com customers will have
access to real time, on-line scheduling and wireless dispatching of home
repair and home improvement services. The Company made an investment of
approximately $500,000 in OurHouse.com in connection with its distribution
arrangement with OurHouse.com.

      MDSI is also engaged in negotiations with BellSouth Wireless Data
("Bellsouth"), a company with which it has a current business relationship,
to finalize the terms of an agreement to integrate MDSI's ASP site with
BellSouth's Intelligent Wireless Network. Under the proposed agreement, the
parties intend to offer MDSI's eBusiness solutions jointly with airtime from
BellSouth's network. MDSI and BellSouth intend to jointly market the bundled
products, initially to small- to medium-sized utility and home service
companies.

      MDSI believes that its eBusiness products will initially appeal to
smaller customers who cannot afford the upfront costs of on-site
implementations, and who do not have the internal technical resources to
operate such systems. Because MDSI intends to offer its eBusiness products on
a monthly subscription and/or transaction fee basis, the products have the
potential to add a recurring revenue stream and may reduce MDSI's dependence
on large contracts and individual customers. See "Forward-Looking Statements."

Products (eBusiness)

      MDSI's eBusiness products are designed to leverage MDSI's core Advantex
products, including the wireless scheduling and dispatching technology.
MDSI's latest version of its Advantex platform, called R7, has been designed
to enable an ASP deployment. The eBusiness product, known as "eAdvantex",
represents a modular, configurable version of Advantex that can be configured
to support the needs of a variety of potential customers from a centrally
hosted system.  MDSI anticipates that additional vertical market versions of
eAdvantex may be developed as initial customers are established. See
"Forward-Looking Statements."

Professional and Customer Support Services (eBusiness)

      The Company is in the process of establishing a comprehensive, 7-day,
24-hour customer service support center to provide various levels of customer
support to its eBusiness customers. The Company is also conducting benchmarking
activities to assist in the design and operation of its data center. MDSI
intends to provide professional services in conjunction with the deployment of
its ASP offerings. These professional services personnel will draw upon the
experience of existing MDSI personnel and will assist in the configuration of
MDSI's systems to meet the needs of potential customers in the target markets.

Sales and Marketing (eBusiness)

      The Company intends to market its eBusiness products through a direct
sales force. The Company also intends to use up to three other channels to
market its eBusiness products. First, the Company intends to enter into
agreements relationships with ASP's that are offering end-to-end suites of
operating solutions to MDSI's targeted vertical markets, such as the
telecommunications, utility and insurance markets. Under this type of
arrangement, MDSI would link its ASP site to the ASP's site to offer Advantex as
the workforce management component of the total solution. MDSI has yet to enter
into any of these agreements. Second, MDSI intends to expand its agreements with
wireless carriers and/or enter into new agreements with such carriers whereby
the carrier's network services would be


                                       9
<PAGE>

integrated with MDSI's ASP site, allowing MDSI and the wireless carriers to
bundle airtime with workforce management and to jointly market the bundled
products to customers. MDSI is currently engaged in negotiations with
BellSouth with respect to a joint marketing agreement. Third, the Company
intends to enter into agreements with operators of Internet sites that
aggregate smaller service providers for home services, such as plumbing or
lawn care. In this case, the Company intends to offer its non-configurable
scheduling and dispatching products to such service providers. MDSI is
currently engaged in negotiations in enter into an agreement of this type
with OurHouse.com. See "Forward-Looking Statements."

Competition (eBusiness)

      The Company will face competition from a number of existing competitors
and emerging Internet-based competitors in the eBusiness field. Existing
competitors including iMedion, ClickService (formerly IET), FieldCentrix, and
eDispatch. The Company believes that these competitors are primarily
targeting smaller-sized businesses with an ASP service offering. These
companies offer a "basic" scheduling and dispatch system. New competitors
targeting Internet intermediaries for the provision of scheduling and
dispatch software services include PointServe, ServeClick and X-Time. These
competitors are specifically focused on Internet-based scheduling and
dispatching services for the growing general services market, but do not
currently offer a wireless solution.

      There can be no assurance that the Company will be able to successfully
develop its ebusiness strategy or that it will be able to compete
successfully against current or future competitors or alliances of such
competitors, or that competitive pressures faced by the Company will not
materially adversely affect its business, financial condition, operating
results and cash flows.

Risk Factors

      The Company's business is subject to the following risks. These risks also
could cause actual results to differ materially from results projected in any
forward-looking statement in this report.

Potential Fluctuations in Quarterly Operating Results

      The Company's results of operations have fluctuated in the past and are
likely to continue to fluctuate from period to period depending on a number of
factors, including the timing and receipt of significant orders, the timing of
completion of contracts, increased competition, changes in the demand for the
Company's products and services, the cancellation of contracts, the timing of
new product announcements and introductions, changes in pricing policies by the
Company and its competitors, delays in the introduction of products or
enhancements by the Company, expenses associated with the acquisition of
products or technology from third parties, the mix of sales of the Company's
products and services and third party products, seasonality of customer
purchases, personnel changes, the mix of international and North American
revenue, tax policies, foreign currency exchange rates and general economic
conditions.

      The Company relies upon its ability to implement and integrate mobile
workforce management solutions on schedule and to the satisfaction of its
customers. The Company from time to time has experienced certain implementation
and other problems that have delayed the completion of certain projects,
including the failure of third parties to deliver products or services on a
timely basis and delays caused by customers. Because the Company currently
recognizes revenue on a percentage of completion method, delays in completion of
certain contracts has caused delays in recognition of revenue and, consequently,
unanticipated fluctuations in quarterly results. There can be no assurance that
the Company will be able to complete current projects or implement future
systems on a timely and cost-effective basis or that delays will not result in
cancellations of contracts or result in the imposition of substantial penalties.
Any such material delay, cancellation or penalty could have a material adverse
effect upon the Company's business, financial condition, operating results and
cash flows.

      Because the Company is unable to forecast with certainty the receipt of
orders for its products and services and the Company's expense levels are
relatively fixed and are based, in part, upon its expectation of future revenue,
if revenue levels fall below expectations as a result of a delay in completing a
contract, the inability to obtain new contracts, the cancellation of an existing
contract or otherwise, operating results are likely to be adversely effected. As
a result, net income may be disproportionately affected because a relatively
small amount of the Company's expenses vary with its revenue. In particular, the
Company plans to increase its operating expenses to implement its eBusiness
strategy, expand its sales and marketing operations, expand its distribution
channels, fund greater levels of research and development, broaden its customer
support capabilities and increase its administrative resources. The Company has
also implemented its eBusiness strategy, which it anticipates it will receive
revenues on a month-to-month or per-transaction basis. The Company anticipates
that costs associated with implementing its eBusiness strategy will increase the
Company's operating expenses and may not be offset by increased revenue until
the Company successfully penetrates the market for its ASP-based service. There
can be no assurance that the Company will effectively compete in this market or
receive sufficient revenues from its eBusiness to offset such costs.


                                       10
<PAGE>

      Based upon all of the foregoing factors, the Company believes that its
quarterly revenue, direct expenses and operating results are likely to vary
significantly in the future, that period-to-period comparisons of the results of
operations are not necessarily meaningful and that such comparisons should not
be relied upon as an indication of future performance. The Company may also
choose to reduce prices or increase spending in response to competition, or to
pursue new market opportunities. See "Forward-Looking Statements". If new
competitors, technological advances by existing competitors or other competitive
factors require the Company to reduce its prices or invest significantly greater
resources in research and development efforts, the Company's operating results
in the future may be adversely affected. There can be no assurance that the
Company will be able to grow in future periods or that it will be able to
sustain its level of total revenue or its rate of revenue growth on a quarterly
or annual basis. It is likely that in some future quarter the Company's
operating results will be below the expectations of public market analysts and
investors. See "Forward Looking Statements". In such event, the price of the
Company's Common Shares would likely be materially adversely affected.

      Since 1996, the Company has been, and anticipates that from time to time
it will be, engaged to provide, in addition to its own products and services,
third party hardware, software and services, which the Company purchases from
vendors and sells to its customers. For the years ended December 31, 1999, 1998
and 1997, 12.9%, 27.7% and 28.6%, respectively, of the Company's revenue was
attributable to third party products and services. Because the revenue generated
from the supply of third party products and services may represent a significant
portion of certain contracts and the installation and rollout of third party
products is generally at the discretion of the customer, the Company may,
depending on the level of third party products and services provided during a
period, experience large quarterly fluctuations in revenue. See "Forward Looking
Statements". In addition, because the Company's gross margins on third party
products and services are substantially below gross margins historically
achieved on revenue associated with MDSI products and services, large
fluctuations in quarterly revenue from the sale of third party products and
services will result in significant fluctuations in direct costs, gross profits,
operating results, cash flows and other items expressed as a percentage of
revenue.

      Certain of the vertical markets targeted by the Company include industries
with implementation requirements that vary seasonally. For example, utility
companies in North America generally have decreased implementation activity in
winter months when such utilities face their greatest consumer demand. As a
result, the Company's results of operations may also vary seasonally, and such
variation may be significant.

Lengthy Sales Cycles for Advantex Products

      The purchase of a mobile workforce management solution is often an
enterprise-wide decision for prospective customers and requires the Company to
engage in sales efforts over an extended period of time and to provide a
significant level of education to prospective customers regarding the use and
benefits of such systems. Due in part to the significant impact that the
application of mobile workforce management solutions has on the operations of a
business and the significant commitment of capital required by such a system,
potential customers tend to be cautious in making acquisition decisions. As a
result, the Company's products generally have a lengthy sales cycle ranging from
several months to several years. Consequently, if sales forecasted from a
specific customer for a particular quarter are not realized in that quarter, the
Company may not be able to generate revenue from alternative sources in time to
compensate for the shortfall. The loss or delay of a large contract could have a
material adverse effect on the Company's quarterly financial condition,
operating results and cash flows, which may cause such results to be less than
analysts' expectations. Moreover, to the extent that significant contracts are
entered into and required to be performed earlier than expected, operating
results for subsequent quarters may be adversely affected. In particular, the
Company has recently experienced an increase in the time necessary to complete
the negotiation and signing of certain contracts with some of its larger
customers.

Dependence on Large Contracts and Concentration of Customers

      The Company's revenue is dependent, in large part, on significant
contracts from a limited number of customers. During the years ended December
31, 1999, 1998 and 1997, approximately 36.6%, 32.6% and 42.5%, respectively, of
the Company's consolidated revenue was attributable to five or fewer customers.
During the years ended December 31, 1999, 1998 and 1997, one customer accounted
for 12.2%, 9.1% and 14.4%, respectively, of the Company's consolidated revenue.
The Company believes that revenue derived from current and future large
customers will continue to represent a significant portion of its total revenue.
See "Forward Looking Statements". The inability of the Company to continue to
secure and maintain a sufficient number of large contracts would have a material
adverse effect on the Company's business, financial condition, operating results
and cash flows. Moreover, the Company's success will depend in part upon its
ability to obtain orders from new customers, as well as the financial condition
and success of its customers and general economic conditions.

      The size of a contract for a particular customer can vary substantially
depending on whether the Company is providing only its own products and services
or is also responsible for supplying third party products and services. The
Company recognizes revenue using the percentage of completion method, which the
Company calculates based on total costs incurred compared to total costs
estimated by the Company for completion. Therefore, any significant increase in
the costs required to complete a project, or any


                                       11
<PAGE>

significant delay in a project schedule, could have a material adverse effect on
that contract's profitability and because of the size of each contract, on the
Company's overall results of operations. The Company from time to time has also
experienced certain implementation and other problems that have delayed the
completion of certain projects, including the failure of third parties to
deliver products or services on a timely basis and delays caused by customers.
The Company's contracts generally provide for payments upon the achievement of
certain milestones. Therefore, any significant delay in the achievement of
milestones on one or more contracts would affect the timing of the Company's
cash flows and could have a material adverse effect on the Company's business,
financial condition, operating results and cash flows. Any significant failure
by the Company to accurately estimate the scope of work involved, plan and
formulate a contract proposal, effectively negotiate a favorable contract price,
properly manage a project or efficiently allocate resources among several
projects could have a material adverse effect on the Company's business,
financial condition, operating results and cash flows.

Potential Fluctuations in Backlog

      The Company's backlog consists of a relatively small number of large
contracts relating to sales of its mobile workforce management and wireless
connectivity software and related equipment and services, and sales of third
party products and services. Due to the long, complex sales process and the mix
of sales of the Company's products and services and third party products and
services, the Company's backlog may fluctuate significantly from
period-to-period. In addition, under the terms of the Company's contracts, the
Company's customers may elect to terminate their contracts with the Company at
any time after notice to the Company or to delay certain aspects of
installation. Due to the relative size of a typical contract compared to the
Company's annual and quarterly revenue, a termination or installation delay of
one or more contracts could have a material adverse effect on the Company's
business, financial condition, operating results and cash flows. Contracts for
software maintenance and support are generally renewable every year and are
subject to renegotiation upon renewal. There can be no assurance that the
Company's customers will renew their maintenance contracts or that renewal terms
will be as favorable to the Company as existing terms.

Limited Operating History; History of Losses; Increased Expenses

      The Company commenced operations in February 1993 and therefore has only a
limited operating history upon which an evaluation of its business and prospects
can be based. Due to non-recurring charges of $6.4 million, including $1.1
million with respect to restructuring certain operations and $5.3 million due to
changes in estimates to complete certain contracts in the UK operations taken in
September 1997, restructuring and reorganization charges of $2.0 million and
$688,374, respectively, taken in connection with the reorganization of the
Company and the acquisition of TelSoft in December 1995, and write-offs of $8.5
million and $10.0 million for acquired research and development taken in
connection with the acquisitions of MDSI UK in June 1996 and Alliance effective
April 1997, respectively, the Company incurred net losses of $11.5 million, $6.0
million , and $1.5 million in the years ended December 31, 1997, 1996 and 1995,
respectively. As of December 31, 1999, the Company had an accumulated deficit of
$12.3 million.

      Although the Company was profitable in its most recently completed fiscal
year, there can be no assurance that, in the future, the Company will realize
revenue growth or be profitable on a quarterly or annual basis. In addition, the
Company plans to increase its operating expenses to implement its eBusiness
strategy, expand its sales and marketing operations, fund greater levels of
research and development, broaden its customer support capabilities and increase
its administration resources. A relatively high percentage of the Company's
expenses is typically fixed in the short term as the Company's expense levels
are based, in part, on its expectations of future revenue. To the extent that
such expenses precede or are not subsequently followed by increased revenue, the
Company's business, financial condition, operating results and cash flows would
be materially adversely affected. In addition, in view of the Company's recent
revenue growth, the rapidly evolving nature of its business and markets, the
Company's limited operating history and the recent acquisitions, the Company
believes that period-to-period comparisons of financial results are not
necessarily meaningful and should not be relied upon as an indication of future
performance.

Integration of Acquisitions

      The Company may, when and if the opportunity arises, acquire other
products, technologies or businesses involved in activities, or having product
lines, that are complementary to the Company's business. Acquisitions involve
numerous risks, including difficulties in the assimilation of the operations,
technologies and products of the acquired companies, the diversion of
management's attention from other business concerns, risks associated with
entering markets or conducting operations with which the Company has no or
limited direct prior experience and the potential loss of key employees of the
acquired company. Moreover, there can be no assurance that any anticipated
benefits of an acquisition will be realized. Future acquisitions by the Company
could result in potentially dilutive issuances of equity securities, the
incurrence of debt and contingent liabilities, amortization of expenses related
to goodwill and other intangible assets and write-off of restructuring costs and
acquired research and development costs, all of which could materially and
adversely affect the Company's financial condition, results of operations and
cash flows.


                                       12
<PAGE>

New Product Development

      The Company expects that a significant portion of its future revenue will
be derived from the sale of newly introduced products and from enhancement of
existing products. See "Forward-Looking Statements." The Company's success will
depend in part upon its ability to enhance its current products on a timely and
cost-effective basis and to develop new products that meet changing market
conditions, including changing customer needs, new competitive product offerings
and enhanced technology. There can be no assurance that the Company will be
successful in developing and marketing on a timely and cost-effective basis new
products and enhancements that respond to such changing market conditions. If
the Company is unable to anticipate or adequately respond on a timely or
cost-effective basis to changing market conditions, to develop new software
products and enhancements to existing products, to correct errors on a timely
basis or to complete products currently under development, or if such new
products or enhancements do not achieve market acceptance, the Company's
business, financial condition, operating results and cash flows could be
materially adversely affected. In light of the difficulties inherent in software
development, the Company expects that it will experience delays in the
completion and introduction of new software products. See "Forward-Looking
Statements."

eBusiness Development

      The Company intends to sell its Advantex family of mobile workforce
management and wireless connectivity application software products over the
Internet from a wirelessly-enabled ASP site on subscription or "per
transaction" basis. The Company's eBusiness products are targeted at Internet
intermediaries who offer a wide range of services, including home services
that to consumers and small and medium-sized businesses. The Company
anticipates that its operating expenses will increase as the Company
establishes a comprehensive 7 day, 24 hour customer service support center to
provide various levels of customer support for its eBusiness customers and
increases its development and marketing efforts. The Company does not
currently have any eBusiness customers, and there can be no assurance that
the Company will successfully implement its eBusiness strategy. There also
can be no assurance that the Company will be able to compete successfully
against current or future competitors or alliances of such competitors, or
that competitive pressures faced by the Company will not materially adversely
affect its business, financial condition, operating results and cash flows.

Management of Growth

      Since its inception, the Company has experienced rapid growth in product
sales, personnel, research and development activities, number and complexity of
products, the number and geographic focus of its targeted vertical markets and
product distribution channels. The total number of employees of the Company has
grown from nine employees in Canada in February 1993 to 453 employees located in
Canada, the United States and other international locations at December 31,
1999. In addition, the recent acquisition of Alliance has increased the number
of products the Company supports and markets, as well as the number of vertical
markets into which it sells products. The Company has also recently expanded the
geographical areas in which it operates. The Company believes that continued
growth in the number and complexity of products and in the number of personnel
will be required to maintain the Company's competitive position. The Company's
rapid growth, coupled with the rapid evolution of the Company's markets, has
placed, and is likely to continue to place, significant strains on its
management, administrative, operational and financial resources, as well as
increased demands on its internal systems, procedures and controls. The
Company's ability to manage recent and future growth will require the Company to
continue to improve its financial and management controls, reporting systems and
procedures on a timely basis, to implement new systems as necessary and to
expand, train, motivate and manage its sales and technical personnel. There can
be no assurance that the Company will be able to manage its growth successfully.
Failure to do so could have a material adverse effect on the Company's business,
financial condition, operating results and cash flows.

Dependence on Key Personnel

      The Company's performance and future operating results are substantially
dependent on the continued service and performance of its senior management and
key technical and sales personnel. The Company intends to hire a significant
number of additional technical and sales personnel in the next year. See
"Forward-Looking Statements." Competition for such personnel is intense, and
there can be no assurance that the Company can retain its key technical, sales
and managerial employees or that it will be able to attract or retain
highly-qualified technical and managerial personnel in the future. The loss of
the services of any of the Company's senior management or other key employees or
the inability to attract and retain the necessary technical, sales and
managerial personnel could have a material adverse effect upon the Company's
business, financial condition, operating results and cash flows.

Dependence on Selected Vertical Markets

      Prior to 1996, substantially all of the Company's revenue was derived from
the sale of products and services to customers in the utility market. For the
years ended December 31, 1997 and 1996, the utility market accounted for greater
than 50% of the Company's revenue. In those years, the Company sought to reduce
its reliance on the utility market by developing or acquiring


                                       13
<PAGE>

compatible products for organizations with mobile workforces in other vertical
markets. In 1998, the utility market accounted for greater than 40% of the
Company's revenue. In 1999, the telecommunications market accounted for 48% of
the Company's revenue. The Company anticipates that a significant portion of its
future revenue will be generated by sales of products to the telecommunications
market. See "Forward-Looking Statements." A decline in demand for the Company's
products in the utility or telecommunications markets as a result of
competition, technological change or otherwise, would have a material adverse
effect on the Company's business, financial condition, operating results and
cash flows. There can be no assurance that the Company will be able to continue
to diversify its product offerings or revenue base by entering into new vertical
markets.

Dependence on Marketing Relationships

      The Company's products are marketed by the Company's direct field sales
force as well as by resellers. The Company's existing agreements with resellers
of its products are nonexclusive and may be terminated by either party without
cause. Such organizations are not within the control of the Company, are not
obligated to purchase products from the Company and may also represent and sell
competing products. There can be no assurance that the Company's existing
resellers will continue to provide the level of services and technical support
necessary to provide a complete solution to the Company's customers or that they
will not emphasize their own or third-party products to the detriment of the
Company's products. The loss of these resellers, the failure of such parties to
perform under agreements with the Company or the inability of the Company to
attract and retain new resellers with the technical, industry and application
experience required to market the Company's products successfully could have a
material adverse effect on the Company's business, financial condition,
operating results and cash flows. The Company expects that it may enter into
certain joint ventures in order to facilitate its expansion into other vertical
markets and geographic areas. See "Forward Looking Statements". To the extent
that such joint ventures are not successful, there could be a material adverse
effect on the Company's business, financial condition, operating results and
cash flows.

      The Company intends to market its eBusiness products through a direct
sales force and through marketing relationships with ASP's that are offering
end-to-end suites of operating solutions to MDSI's targeted vertical markets,
wireless carriers and operators of Internet sites that aggregate smaller service
providers for home services. The Company anticipates that these marketing
relationships will be nonexclusive and may be terminated by either party without
cause. There can be no assurance that the Company's eBusiness solutions will be
compatible with these marketing partners or that they will not emphasize their
own or third-party products to the detriment of the Company's products. The
Company's failure to enter into marketing relationships, the failure of the
parties to perform under these agreements or the inability of the Company to
provide effective eBusiness solutions successfully could have a material adverse
effect on the Company's business, financial condition, operating results and
cash flows.

Competition

      The markets for mobile workforce management applications, wireless
connectivity software, mobile data network equipment and mobile computing
devices are highly competitive. Numerous factors affect the Company's
competitive position, including price, product features, product performance and
reliability, ease of use, product scalability, product availability on multiple
platforms (both server and mobile workstation), ability to implement mobile
workforce management solutions domestically and internationally while meeting
customer schedules, integration of products with other enterprise solutions,
availability of project consulting services and timely ongoing customer service
and support.

      Within these markets, there are a small number of new ventures, either
small companies attempting to establish a business in this market or large
companies attempting to diversify their product offerings. The Company expects
such competition to intensify as acceptance and awareness of mobile data
communications and technology continue. See "Forward Looking Statements". In
addition, a small number of the Company's potential customers develop software
solutions internally, thereby eliminating the requirement for suppliers such as
the Company. Current or potential competitors may establish cooperative
arrangements among themselves or with third parties to increase the ability of
their products to address customer requirements.

      Certain of the Company's competitors have substantially greater financial,
technical, marketing and distribution resources than the Company. As a result,
they may be able to respond more quickly to new or emerging technologies and
changing customer requirements, or to devote greater resources to the
development and distribution of existing products. There can be no assurance
that the Company will be able to compete successfully against current or future
competitors or alliances of such competitors, or that competitive pressures
faced by the Company will not materially adversely affect its business,
financial condition, operating results and cash flows.

      The Company primarily competes in the utility market with Utility
Partners, L.C., M3i Systems, Inc. and Alterra Corp. The Company has several
competitors in the telecommunications market, a few of which have historical
relationships with certain of the large telecommunications companies. The
Company's primary competitor for telecommunications customers are Lucent
Technologies, Inc. and Telcordia. The Company's principal competitors in the
cable market are Telcordia and MobileForce Technologies, Inc. In the general
field service market, the Company's principal competitors are Astea
International Inc. and Metrix Inc. In the public safety

                                       14
<PAGE>

market, the Company's principal competitors are Cerulean, PRC, Tiberon Systems
and New World Systems. The Company's eBusiness will face competition from a
number of existing competitors and emerging Internet-based competitors,
including iMedion, ClickService (formerly IET), FieldCentrix, eDispatch,
PointServe, ServeClick and X-Time.

Risk of Product Defects

      Software products, including those offered by the Company, from
time-to-time contain undetected errors or failures. There can be no assurance
that, despite testing by the Company and by current and potential customers,
errors will not be found in the Company's products. Such errors could result in
loss of or delay in market acceptance of the Company's products, which could
have a material adverse effect on the Company's business, financial condition,
operating results and cash flows.

Proprietary Technology

      The Company's success is dependent on its ability to protect its
intellectual property rights. The Company relies principally upon a combination
of copyright, trademark, trade secret and patent laws, non-disclosure agreements
and other contractual provisions to establish and maintain its rights. To date,
the Company has been granted trademark registrations or has registrations
pending in the United States, Canada and the European Community for the MDSI,
Advantex and Compose marks. Other than one patent pending for certain
technology, MDSI has not sought patent protection for its products. As part of
its confidentiality procedures, the Company generally enters into nondisclosure
and confidentiality agreements with each of its key employees, consultants,
distributors, customers and corporate partners, to limit access to and
distribution of its software, documentation and other proprietary information.
There can be no assurance that the Company's efforts to protect its intellectual
property rights will be successful. Despite the Company's efforts to protect its
intellectual property rights, unauthorized third parties, including competitors,
may be able to copy or reverse engineer certain portions of the Company's
software products, and use such copies to create competitive products.

      Policing the unauthorized use of the Company's products is difficult, and,
while the Company is unable to determine the extent to which piracy of its
software products exists, software piracy can be expected to continue. In
addition, the laws of certain countries in which the Company's products are or
may be licensed do not protect its products and intellectual property rights to
the same extent as do the laws of Canada and the United States. As a result,
sales of products by the Company in such countries may increase the likelihood
that the Company's proprietary technology is infringed upon by unauthorized
third parties.

      In addition, because third parties may attempt to develop similar
technologies independently, the Company expects that software product developers
will be increasingly subject to infringement claims as the number of products
and competitors in the Company's industry segments grow and the functionality of
products in different industry segments overlaps. See "Forward Looking
Statements". Although the Company believes that its products do not infringe on
the intellectual property rights of third parties, there can be no assurance
that third parties will not bring infringement claims (or claims for
indemnification resulting from infringement claims) against the Company with
respect to copyrights, trademarks, patents and other proprietary rights. Any
such claims, whether with or without merit, could be time consuming, result in
costly litigation and diversion of resources, cause product shipment delays or
require the Company to enter into royalty or licensing agreements. Such royalty
or licensing agreements, if required, may not be available on terms acceptable
to the Company or at all. A claim of product infringement against the Company
and failure or inability of the Company to license the infringed or similar
technology could have a material adverse effect on the Company's business,
financial condition, operating results and cash flows.


                                       15
<PAGE>

Dependence on Third Parties

      Certain contracts require the Company to supply, coordinate and install
third party products and services. The Company believes that there are a number
of acceptable vendors and subcontractors for most of its required products, but
in many cases, despite the availability of multiple sources, the Company may
select a single source in order to maintain quality control and to develop a
strategic relationship with the supplier or may be directed by a customer to use
a particular product. The failure of a third party supplier to provide a
sufficient supply of parts and components or products and services in a timely
manner could have a material adverse effect on the Company's results of
operations. In addition, any increase in the price of one or more of these
products, components or services could have a material adverse effect on the
Company's business, financial condition, operating results and cash flows.

      Additionally, under certain circumstances, the Company supplies products
and services to a customer through a larger company with a more established
reputation acting as a project manager or systems integrator. In such
circumstances, the Company has a sub-contract to supply its products and
services to the customer through the prime contractor. In these circumstances,
the Company is at risk that situations may arise outside of its control that
could lead to a delay, cost over-run or cancellation of the prime contract which
could also result in a delay, cost over-run or cancellation of the Company's
sub-contract. The failure of a prime contractor to supply its products and
services or perform its contractual obligations to the customer in a timely
manner could have a material adverse effect on the Company's financial
condition, results of operations and cash flows.

Exchange Rate Fluctuations

      Because the Company's reporting currency is the Canadian dollar, its
operations outside Canada face additional risks, including fluctuating currency
values and exchange rates, hard currency shortages and controls on currency
exchange. The Company has operations outside Canada and is hedged, to some
extent, from foreign exchange risks because of its ability to purchase, develop
and sell in the local currency of those jurisdictions. In addition, the Company
does enter into foreign currency contracts under certain circumstances to reduce
the Company's exposure to foreign exchange risks. There can be no assurance,
however, that the attempted matching of foreign currency receipts with
disbursements or hedging activities will adequately moderate the risk of
currency or exchange rate fluctuations which could have a material adverse
effect on the Company's business, financial condition, operating results and
cash flows. In addition, to the extent the Company has operations outside
Canada, the Company is subject to the impact of foreign currency fluctuations
and exchange rate charges on the Company's reporting in its financial statements
of the results from such operations outside Canada. Since such financial
statements are prepared utilizing Canadian dollars as the basis for
presentation, results from operations outside Canada reported in the financial
statements must be restated into Canadian dollars utilizing the appropriate
foreign currency exchange rate, thereby subjecting such results to the impact of
currency and exchange rate fluctuations.

Risks Associated with International Operations

      In the years ended December 31, 1999, 1998 and 1997 revenue derived from
sales outside of North America accounted for approximately 24.8%, 3.4% and
10.1%, respectively of the Company's total revenue. Because the Company's
revenue is dependent, in large part, on significant contracts with a limited
number of customers, the percentage of the Company's revenues that is derived
from sales outside of North America has fluctuated, and may continue to
fluctuate, from period-to-period. The Company believes that its continued growth
and profitability will require additional expansion of its sales in foreign
markets, and that revenue derived from international sales will account for a
significant percentage of the Company's revenue for the foreseeable future. This
expansion has required and will continue to require significant management
attention and financial resources. The inability of the Company to expand
international sales in a timely and cost-effective manner could have a material
adverse effect on the Company's business, financial condition, operating results
and cash flows. There are a number of risks inherent in the Company's
international business activities, including changes in regulatory requirements,
tariffs and other trade barriers, costs and risks of localizing products for
foreign markets, longer accounts receivable payment cycles, difficulties in
collecting payments, reduced protection for intellectual property, potentially
adverse tax consequences, limits on repatriation of earnings, the burdens of
complying with a wide variety of foreign laws, nationalization, war,
insurrection, terrorism and other political risks and factors beyond the
Company's control. Fluctuations in currency exchange rates could adversely
affect sales denominated in foreign currencies and cause a reduction in revenue
derived from sales in a particular country. In addition, revenue of the Company
earned abroad may be subject to taxation by more than one jurisdiction, thereby
adversely affecting the Company's earnings. There can be no assurance that such
factors will not materially adversely affect the Company's future international
sales and, consequently, the Company's business, financial condition operating
results and cash flows.

Product Liability

      The license and support of products by the Company may entail the risk of
exposure to product liability claims. A product liability claim brought against
the Company or a third party that the Company is required to indemnify, whether
with or without


                                       16
<PAGE>

merit, could have a material adverse effect on the Company's business, financial
condition, operating results and cash flows. The Company carries insurance
coverage for product liability claims which it believes to be adequate for its
operations.

Concentration of Stock Ownership; Anti-Takeover Effects; Investment Canada Act

      The Company's directors, officers and their respective affiliates, in the
aggregate, beneficially own approximately 21.0% of the outstanding Common
Shares. As a result, these shareholders, if acting together, may be able to
exercise significant influence over the Company and many matters requiring
shareholder approval, including the election of directors and approval of
significant corporate transactions. Such concentration of ownership may under
certain circumstances also have the effect of delaying, deferring or preventing
a change in control of the Company.

      An investment in the Common Shares of the Company which results in a
change of control of the Company may, under certain circumstances, be subject to
review and approval under the Investment Canada Act if the party or parties
acquiring control is not a Canadian person (as defined therein). Therefore, the
Canadian regulatory environment may have the effect of delaying, deferring or
preventing a change in control of the Company.

      The Company is organized under the laws of Canada and, accordingly, is
governed by the CBCA. The CBCA differs in certain material respects from laws
generally applicable to United States corporations and shareholders, including
the provisions relating to interested directors, mergers and similar
arrangements, takeovers, shareholders' suits, indemnification of directors and
inspection of corporate records.

      In December 1998, the Company implemented a stock rights plan (the
"Plan"). Pursuant to the Plan, shareholders of record on December 17, 1998
received a dividend of one right to purchase, for CDN$140, one Common Share of
the Company. The rights are attached to the Company's Common Shares and will
also become attached to Common Shares issued in the future. The rights will not
be traded separately and will not become exercisable until the occurrence of a
triggering event, defined as an accumulation by a single person or group of 20%
or more of the Company's Common Shares. After a triggering event, the rights
will detach from the Common Shares. If the Company is then merged into, or is
acquired by, another corporation, the Company may either (i) redeem the rights
or (ii) permit the rights holder to receive in the merger Common Shares of the
Company or of the acquiring company equal to two times the exercise price of the
right (i.e., CDN$280). In the latter instance, the rights attached to the
acquirer's stock become null and void. The effect of the rights program is to
make a potential acquisition of the Company more expensive for the acquirer if,
in the opinion of the Company's Board of Directors, the offer is inadequate.
While the Company is not aware of any circumstance that might result in the
acquisition of a sufficient number of shares of the Company's Common Shares to
trigger distribution of the Rights, existence of the Rights could discourage
offers for the Company's stock that may exceed the current market price of the
stock, but that the Board of Directors deems inadequate.

      As a result of being a reporting issuer in certain provinces of Canada,
the Company is required to file certain reports in such jurisdictions. As part
of such reports, the Company is required to file consolidated financial
statements prepared in accordance with generally accepted accounting principles
as applied in Canada ("Canadian GAAP"). Canadian and US GAAP differ in certain
respects, including the treatment of certain reorganization costs and acquired
research and development costs. As a result, the Company's Consolidated
Financial Statements included in this report may differ materially from the
financial statements filed by the Company in Canada.

Market for the Common Shares; Potential Volatility of Stock Price

      The trading prices of the Common Shares have been subject to wide
fluctuations since trading of the Company's shares commenced in December 1995.
There can be no assurance that the market price of the Common Shares will not
significantly fluctuate from its current level. The market price of the Common
Shares may be subject to wide fluctuations in response to quarterly variations
in operating results, announcements of technological innovations or new products
by the Company or its competitors, changes in financial estimates by securities
analysts, or other events or factors. In addition, the financial markets have
experienced significant price and volume fluctuations for a number of reasons,
including the failure of the operating results of certain companies to meet
market expectations that have particularly affected the market prices of equity
securities of many high-technology companies that have often been unrelated to
the operating performance of such companies. These broad market fluctuations, or
any industry-specific market fluctuations, may adversely affect the market price
of the Common Shares. In the past, following periods of volatility in the market
price of a company's securities, securities class action litigation has often
been instituted against such a company. Such litigation, whether with or without
merit, could result in substantial costs and a diversion of management's
attention and resources, which would have a material adverse effect on the
Company's business, financial condition, operating results and cash flows.

Item 2: Properties

      The Company occupies approximately 92,000 square feet of leased office
space at its headquarters in Richmond, British Columbia for its product
development, marketing, support, administration and sales operations. The
Company has sub-let approximately 16,500 of this space until June 30, 2001 after
which time it intends to occupy such space. The lease expires on November 30,
2008 with two options to renew for five years each. The Company also maintains
an office in Itasca, Illinois. The Itasca office lease is for approximately
29,000 square feet and terminates on November 30, 2009.

Item 3: Legal Proceedings

      As of the date hereof, there is no material litigation pending against the
Company. From time to time, the Company is a party to litigation and claims
incident to the ordinary course of its business. While the results of litigation
and claims cannot be predicted with certainty, the Company believes that the
final outcome of such matters will not have a material adverse effect on the
Company's business, financial condition, operating results and cash flows.

Item 4: Submission of Matters to a Vote of Security Holders

Price Range of Common Shares

      The Company's Common Shares began trading on The Toronto Stock Exchange
and on the Montreal Exchange under the symbol "MMD" on December 20, 1995 and
began trading on the NASDAQ National Market System under the symbol "MDSIF" on
November 26, 1996. The Company changed its NASDAQ National Market System trading
symbol to "MDSI" in April 1999. In December 1999, the Company's listing on the
Montreal Exchange was automatically withdrawn as part of a restructuring plan of
the Canadian stock exchanges. Prior to December 20, 1995, there was no public
market for the Common Shares. The following table sets forth, for the periods
indicated, the high and low sale prices for the Common Shares as reported on The
Toronto Stock Exchange and the NASDAQ National Market System with their

      As of December 31, 1999 the Company had approximately 205 shareholders of
record (including nominees and brokers holding street accounts), 98 shareholders
of whom had addresses in the United States and who held 4,509,480 Common Shares,
or 61.1 % of the Company's outstanding Common Shares.

      The Company has never paid dividends on its Common Stock. The Company
currently intends to retain earnings for use in its business and does not
anticipate paying any dividends in the foreseeable future. The Company's current
bank credit agreement prohibits the payment of dividends without prior consent
of the lender.

Item 7: Management's Discussion and Analysis of Financial Condition and Results
of Operations

      The following discussion contains "forward looking statements" within the
meaning of Section 21E of the Securities Exchange Act of 1934. The fourth
paragraph under "Revenue", and the paragraphs entitled "Research and
Development", "Sales and Marketing" , and "General and Administrative" , in the
section entitled "Year ended December 31, 1999 Compared to the Year ended
December 31, 1998" contain forward looking statements. Actual results could
differ materially from those projected in the forward looking statements as a
result of the Company's ability to accelerate or defer operating expenses,
achieve revenue in a particular period, hire new personnel and other factors set
forth under "Business-Risk Factors" in Item 1 of this Annual Report on Form
10-K. In particular, note the Business-Risk Factors entitled "Potential
Fluctuations in Quarterly Operating Results", "Lengthy Sales Cycles",
"Dependence on Large Contracts and Concentration of Customers", "Limited
Operating History; Increased Expenses", "Integration of Acquisitions" and

"Market Risk".

Overview

      MDSI develops, markets, implements and supports mobile workforce
management and wireless connectivity software and related network and mobile
computing equipment for use by a wide variety of companies that have substantial
mobile workforces, such as utilities, telecommunications companies, taxi service
providers, courier companies and roadside recovery organizations. MDSI's
products are used by such companies in conjunction with public and private
wireless data communications networks to provide comprehensive solutions for the
automation of business processes associated with the scheduling, dispatching and
management of a mobile workforce. The Company's products provide a
cost-effective method for companies with mobile workers to utilize data
communications to communicate with such workers, and for such workers to
interface on a real-time basis with their corporate information systems.

      The Company's revenue is derived from (i) software and services,
consisting of the licensing of software and provision of related services,
including project management, installation, integration, customization and
training; (ii) third party products and services, consisting of the provision of
non-MDSI products and services as part of the total contract; terminal and
infrastructure equipment consisting of the sale of mobile computing devices,
related in-vehicle equipment and wireless data network equipment manufactured by
the Company; (iii) terminal and infrastructure equipment consisting of the sale
of mobile computing devices, related in-vehicle equipment and wireless data
network equipment manufactured by the Company; and (iv) maintenance and support,
consisting of the provision of after-sale support services as well as hourly,
annual or extended maintenance contracts.

      The implementation of a complete mobile data solution requires a wireless
data communications network, a land-based data communications network, mobile
computing devices integrated with wireless data communication modems, host
computer equipment, industry specific application software, wireless
connectivity software and a variety of services to manage and install these
components, integrate them with an organization's existing computer systems, and
configure or customize the software to meet customer requirements. Frequently,
in the Company's larger contracts only a limited number of the mobile computing
devices and in-vehicle equipment are installed initially, with the balance
implemented over a rollout period that may extend up to one year or more. Where
increases in mobile work forces require, or where additional departments of
mobile workers are added, additional mobile computing devices may be installed.

      Revenue for software and services has historically accounted for a
substantial portion of the Company's revenue. Typically, the Company enters
into a fixed price contract with a customer for the licensing of selected
software products and the provision of specific services that are generally
performed within six to twelve months. Pricing for these contracts includes
license fees as well as a fee for professional services. The Company generally
recognizes total revenue for software and services associated with a contract
using a percentage of completion method based on the total costs incurred over
the total estimated costs to complete the contract.


                                       21
<PAGE>

      The Company's customers typically enter into ongoing maintenance
agreements that provide for maintenance and technical support services for a
period commencing after expiration of the initial warranty period.
Maintenance agreements typically have a term of twelve months and are
invoiced either annually or monthly. Revenue for these services is recognized
ratably over the term of the contract.

      Prior to 1996, MDSI typically supplied only the MDSI application and
wireless connectivity software and related services as part of its contract with
a customer. The portion of contracts requiring the supply of third party
products and services was not material and was not separated for revenue
purposes. Beginning in 1996, however, the Company was called on to provide, in
addition to MDSI products and services, certain third party products, such as
host computer hardware and operating system software, and mobile computing. The
Company recognizes revenue for the supply of third party hardware upon transfer
of title to the customer. The Company recognizes revenue for the supply of third
party services using a percentage of completion method based on the costs
incurred over the total estimated cost to complete the third party services
contract.

      The Company believes that it will often supply some portion of third party
products and services to customers where it is successful in selling its own
products and services. There can be no assurance, however, that any contracts
entered into by the Company to supply third party software and products in the
future will represent a substantial portion of revenue in any future period.
Since the revenue generated from the supply of third party products and services
may represent a significant portion of certain contracts and the installation
and rollout of third party products is generally at the discretion of the
customer, the Company may, depending on the level of third party products and
services provided during a period, experience large quarterly fluctuations in
revenue.

      The Company's revenue is dependent, in large part, on significant
contracts from a limited number of customers. As a result, any substantial
delay in the Company's completion of a contract, the inability of the Company
to obtain new contracts or the cancellation of an existing contract by a
customer could have a material adverse effect on the Company's results of
operations. Some of the Company's contracts are cancelable upon notice by the
customer. The loss of certain contracts could have a material adverse effect
on the Company's business, financial condition, operating results and cash
flows. As a result of these and other factors, the Company's results of
operations have fluctuated in the past and may continue to fluctuate from
period-to-period.

Effects of Acquisitions

      The consolidated financial statements of the Company reflect the
acquisition of Alliance effective April 17, 1997, which was accounted for
using the purchase method.

      On April 17, 1997, the Company entered into an agreement to acquire
Alliance which was completed July 1, 1997. Alliance is a supplier of mobile
workforce management solutions to the utility, public safety and cable markets.
The acquisition resulted in the write-off of $10.0 million associated with
acquired research and development. The Company's results of operations for the
year ended December 31, 1997 include only the results of operations of Alliance
from April 17, 1997.

      The Company has a limited history of operations on a combined basis with
Alliance. In addition, since the acquisition of Alliance, the Company has
restructured certain aspects of this operation. As a result, the financial
information presented in this Annual Report is not indicative of the results
that would have been obtained had the acquisitions occurred prior to the
commencement of the periods covered herein, and such information should not be
relied upon as an indication of future performance.

Disposition of Transportation Business Unit

      In February 1999, the Company's Board of Directors approved a plan to
dispose of its Delivery segment (Transportation Business Unit). Effective June
1, 1999, the Company completed the sale of the transportation business unit to
Digital Dispatch Systems, Inc. ("DDS"), a supplier of dispatch systems to the
taxi market for proceeds of $5,532,730. The proceeds comprised of common shares
of DDS, representing an 11% interest in DDS, and a promissory note in the
principal amount of $500,000, due January 1, 2001, bearing interest at 8% per
annum.

      Under the terms of the agreement between the Company and DDS, the Company
has retained certain assets and liabilities of the discontinued operations. The
Company expects that it will liquidate these assets and liabilities by June 30,
2000. In addition, the Company has agreed to complete the implementation of a
large contract with a taxi customer. The Company has experienced, and is
continuing to experience delays in the implementation of this contract. If the
Company is unable to complete the implementation of the contract on a timely
basis, the taxi customer has the right to cancel the contract. Any such
cancellation may require the Company to reimburse the customer for payments
received to date. The Company believes that it has adequately provided for the
costs to complete this contract.

Disposition of Transportation Business Unit (Continued)

      As a result of the Company's decision to dispose of its Delivery segment,
the Delivery segment has been classified as a discontinued operation and the
results of operation, financial position and cash flow for this segment have
been segregated from those of continuing operations. The following discussion
and analysis of the Company's results of operations excludes the Delivery
segment for the current and corresponding prior period.

      The Company's net income of $1.4 million for the year ended December
31, 1999 was comprised of a $7.2 million after-tax profit from continuing
operations and an after-tax loss of $5.9 million on discontinued operations.
The loss on discontinued operations is comprised of loss on operations of
$2.4 million and loss on disposal of $3.5 million. There is no tax effect on
these losses. The discontinued operating loss includes not only the results
of operations but also foreign exchange losses and provisions against
contracts to the measurement date of February 25, 1999. The loss on disposal
includes the operating results from the measurement date to the effective
date, the costs of disposal, severance costs, and the estimated costs to
complete the remaining taxi contract.

Year ended December 31, 1999 Compared to the Year ended December 31, 1998

      Revenue - Revenue increased by $10.3 million (15.4%) for the year ended
December 31, 1999 as compared to the year ended December 31, 1998. The increase
was primarily due to the increase in software and services which was partially
offset by a decrease in the revenue earned from third party products and
services.

      Software and services revenue increased by $16.4 million (38.4%) for the
year ended December 31, 1999 as compared to the year ended December 31, 1998.
This increase was due to an 92% increase in the revenues earned from customers
in the telecommunications market.

      Third party products and services revenue decreased by $8.6 million
(46.4%) for the year ended December 31, 1999 compared to the year ended December
31, 1998. Third party products and services revenue is primarily earned from
certain customers in the utility market pursuant to agreements under which the
Company provides third party products and services, typically host computer
equipment and mobile computing devices, as part of the installation of software
and provision of services. Revenue from deliveries of third party products and
services will fluctuate from period to period given the timing of certain
contracts and the rollout schedules which are established primarily by the
customers. Accordingly, this will result in large fluctuations in revenue,
direct costs, gross profits and income from operations from one period to
another.

      Maintenance and support revenue was $8.3 million for the year ended
December 31, 1999 as compared to $5.7 million for the year ended December 31,
1998, an increase of 44.3%. Typically, maintenance and support revenue will
increase with the number of customers using MDSI's software.

      Direct Costs. Direct costs were 43.3% of revenue for the year ended
December 31, 1999 as compared to 47.8% for the year ended December 31, 1998.
Direct costs include labor and other costs directly related to a project
including those related to the provision of services and support, and costs
related to host equipment and mobile devices on behalf of third party product
sales. Labor costs include direct payroll, benefits and overhead charges. The
decrease in proportion of direct costs to revenue relates primarily to the
decrease third -party products and services, which have higher direct costs.

      Gross Margins. Gross margins were 56.7% of revenue for the year ended
December 31, 1999 as compared to 52.2% for the year ended December 31, 1998. The
change in profit margin relates to the change in the mix in revenues. The
proportion in revenue of lower margin third-party products and services
decreased in 1999 compared to 1998.

      Research and Development. Research and development expenses were $10.0
million, or 12.9% of revenue, for the year ended December 31, 1999, compared to
$8.7 million, or 13.0% of revenue, for the year ended December 31, 1998. The
14.6% increase in research and development expenses in 1999 is a result of the
continued development and enhancement of the Company's Advantex products. The
Company anticipates continuing to commit a significant portion of its product
revenues to enhancement of existing products and the development of new
products, resulting in an anticipated increase in the dollar amounts of research
and development expenses.

      Sales and Marketing. Sales and marketing expenses were $13.7 million or
17.6% of revenue for the year ended December 31, 1999 and 17.3% of revenue for
the year ended December 31, 1998. This represents an increase of $2.1 million
(17.8%) as compared to 1998. The increase was primarily due to an increase in
marketing, sales and technical support personnel to support the Company's
increased marketing activities worldwide. The Company anticipates that the
dollar amounts of its sales and marketing expenses will continue to increase as
the result of the Company's commitment to its international marketing effort.

      General and Administrative. General and administrative expenses were $8.3
million, or 10.8% of revenue, for the year ended December 31, 1999 and $5.4
million, or 8.0% of revenue, for the year ended December 31, 1998. This increase
was due primarily to the hiring of additional accounting and administrative
personnel to support the Company's growth. The Company expects that its general
and administrative expenses will increase in the future as the Company expands
its staffing, information systems and other administrative costs to support its
expanding operations.

      Other Income(expense). Other income (expense) was $(1.1) million for the
year ended December 31, 1999 as compared to $0.0 million for the year ended
December 31, 1998. Substantially all of other income (expense) relates to
interest income on cash and short term deposits and fluctuations in foreign
currency denominated assets and liabilities.

      Income Taxes. The Company provided for income taxes on earnings for the
year ended December 31, 1999 at the rate of 29.5%, after adjusting for the
amortization of intangible assets. The Company's effective tax rate reflects the
application of certain operating loss carry forwards against taxable income and
the blended effect of Canadian, US, and other foreign jurisdictions' tax rates.

December 31, 1998 as compared to the year ended December 31, 1997. This increase
in revenue can be attributed to the reflection in the financial statements of a
full year of Alliance's (now MDSI US) operations, in comparison to eight and

of the existing business.

year ended December 31, 1998 as compared to the year ended December 31, 1997.

both the telecommunications and utility markets.

(22.7%) for the year ended December 31, 1998 compared the year ended December
31, 1997. Third party products and services revenue is primarily earned from

December 31, 1998 as compared to 47.1% for the year ended December 31, 1997.

$4.9 million, or 9.3% of revenue, for the year ended December 31, 1997. The
77.2% increase in research and development expenses in 1998 is a result of the
continued development and enhancement of the Company's Advantex products. The

revenues to enhancement of existing products and the development of new
products, resulting in an anticipated increase in the dollar amounts of research
and development expenses.

17.3% of revenue for the year ended December 31, 1998 and 18.2% of revenue for
the year ended December 31, 1997. This represents an increase of $1.9 million
(20.2%) as compared to 1997. The increase was primarily due to an increase in
marketing, sales and technical support personnel to support the Company's
increased marketing activities worldwide. The Company anticipates that the
dollar amounts of its sales and marketing expenses will continue to increase as
the result of the Company's commitment to its international marketing effort.

      General and Administrative. General and administrative expenses were $5.4
million, or 8.0% of revenue, for the year ended December 31, 1998 and $3.9

Quarterly Results of Operations

      The following table sets forth certain unaudited statement of operations
data for each of the eight quarters beginning January 1, 1998 and ending
December 31, 1999 as well as the percentage of the Company's revenue represented
by each item. The unaudited financial statements have been prepared on the same
basis as the audited financial statements contained herein and include all
adjustments, consisting only of normal recurring adjustments, that the Company
considers necessary to present fairly this information when read in conjunction
with the Company's audited financial statements and the notes thereto appearing
elsewhere in this report. In view of the Company's recent growth, its recent
acquisitions and other factors, the Company believes that quarterly comparisons
of its financial results are not necessarily meaningful and should not be relied
upon as an indication of future performance.

Liquidity and Capital Resources

            The Company finances its operations, acquisitions and capital
expenditures with cash generated from operations, loans, private placements and
public offerings of its securities. At December 31, 1999, the Company had cash
and cash equivalents of $21.3 million and working capital of $34.3 million.

            Cash provided by (used in) operating activities was $3.5 million,
$8.4 million and $(1.1) million, respectively for the years ended December 31,
1999, 1998 and 1997. The $3.5 million of cash provided by operating activities
in 1999 comprised $7.2 million net income, non-cash charges of $2.4 million and
$(6.1) million of changes to non-cash working capital items. The changes to
working capital items include a $2.4 million increase in trade receivables, a
$287,000 increase in unbilled receivables, a $1.8 million decrease in prepaid
expenses and a $241,000 increase in accrued liabilities offset by a $4.9 million
decrease in trade payables, a $180,000 increase in taxes payable and a $499,000
decrease in deferred revenue. Unbilled accounts receivable arise where the
Company has earned revenue on a project though has yet to complete specific
billing milestones under the terms of the applicable contract. Deferred revenue
arises where the Company has achieved a billing milestone under a customer
contract but has yet to recognize all of the revenue billed due to the
percentage of completion under the contract. The $1.8 million decrease in
prepaid expenses is primarily attributable to expenses incurred with respect to
the Richmond facility, which were recovered from the landlord during the first
half of 1999.


                                       30

            Cash provided by (used in) financing activities was $20.4 million,
$2.9 million and $(1.7) million, respectively during the years ended December
31, 1999, 1998 and 1997. The cash provided by financing activities in 1999
comprised $2.4 million in capital leases and $18.3 million from the issue of
common shares partially offset by a $377,000 repayment of long-term debt. During
1999, the Company financed a major portion of its capital expenditure program
through capital leases. The $18.3 million received for shares issued was made up
of a 575,000 common shares issue on a private placement for net consideration of
$14.7 million, exercise of stock options for proceeds of $3.2million and
purchases by employees under the Company's share purchase plan of $409,000.

            Cash used in investing activities was $5.7 million, $2.6 million,
$4.1 million, respectively for the years ended December 31, 1999, 1998 and 1997.
Total investing activity in 1999 consisted of $5.9 million for the purchase of
capital equipment, including computer hardware and software for use in research
and development activities and to support the growth of the Company's corporate
information systems.

            Existing sources of liquidity at December 31, 1999 include $21.3
million of cash and cash equivalents and funds available under the Company's
operating line of credit. At the year ended December 31, 1999, the Company's
borrowing capacity under the line of credit was $8 million. Under the terms of
the agreement, borrowings and letters of credit under the line are limited to
60% to 90% of eligible accounts receivable. Borrowings accrue interest at the
bank's prime rate plus 0.5%. At December 31, 1999, the Company was not utilizing
this line of credit.

            The Company believes that future cash flows from operations, and its
borrowing capacity under the operating line of credit will provide sufficient
funds to meet cash requirements for at least the next twelve months.
Commensurate with its past and expected future growth, the Company may increase,
from time to time, its borrowing facility under its operating line of credit to
support its operations. The Company has no material additional commitments other
than operating leases. Future growth or other investing activities may require
the Company to obtain additional equity or debt financing, which may or may not
be available on attractive terms, or at all, or may be dilutive to current or
future shareholders.

Derivative Financial Instruments

      It is the policy of the Company not to enter into derivative financial
instruments for trading purposes. The Company does enter into foreign currency
forward exchange contracts in the ordinary course of business to protect itself
from adverse currency rate fluctuations on certain firm foreign currency
transactions. The Company may also utilize foreign currency exchange contracts
to hedge net assets or liabilities denominated in foreign currencies. These
contracts are generally for eighteen months or less. Gains or losses relating to
hedging firm commitments are deferred and included in the measurement of the
foreign currency transaction subject to the hedge.

      The Company's foreign currency forward contracts are executed with
credit worthy banks and are denominated in currencies of major industrial
countries. As at December 31,1999, the Company had the following foreign
currency forward contracts outstanding: 1) sold 104,000,000 Belgian Franc for
delivery on October 31, 2000 for $4.3 million, 2) sold GBP sterling 350,000
and 180,000 for $ 814,660 and $ 418,860 to be delivered on May 31, 2000 and
September 29, 2000 respectively.

Item 7A: Quantitative and Qualitative Disclosure About Market Risk

      The Company's primary market risk is foreign currency exchange rates. The
Company has established procedures to manage sensitivity to foreign currency
exchange rate market risk. These procedures include the monitoring of the
Company's net exposure to each foreign currency and the use of foreign currency
forward contracts to hedge firm exposures to currencies other than the Canadian
and United States dollars. The Company has operations in the United States and
Europe in addition to its Canadian operations and except as note below did not
hedge these exposures in 1999. However, the Company may from time-to-time hedge
any net exposure to the United States dollar.

      As of December 31, 1999, the potential reduction in future earnings from a
hypothetical instantaneous 10% change in quoted foreign currency exchange rates
applied to the foreign currency sensitive contracts and assets would be
approximately $4.9 million. The foreign currency sensitivity model is limited by
the assumption that all foreign currencies, to which the Company is exposed,
would simultaneously change by 10%. Such synchronized changes are unlikely to
occur. The sensitivity model does not include the inherent risks associated with
anticipated future transactions denominated in foreign currencies or future
forward contracts entered into for hedging purposes.

      The Company has entered into foreign currency forward contracts in respect
of net exposures under customer contracts to the Belgian Franc and Great Britain
Pound. Effective January 1, 1999, the Belgian Franc is tied to the Euro, the new
European Union common currency. The effect of these transactions is to reduce
the potential reduction in future earnings from a hypothetical instantaneous 10%
change in quoted foreign currency exchange rates to $4.1 million.


                                       31

      The Company does not have any material exposure to interest or commodity
risks. The Company is exposed to economic and political changes in international
markets where the Company competes such as inflation rates, recession, foreign
ownership restrictions and other external factors over which the Company has no
control; domestic and foreign government spending, budgetary and trade policies.

Item 11: Executive Compensation

Report of the Compensation Committee

      The Company's compensation program for all executive officers is
administered by the Compensation Committee of the Board of Directors which is
composed of two non-employee directors and one-employee director. The
compensation of the Chairman, Chief Executive Officer (CEO) and the President
and Chief Operating Officer (COO) is determined by the Compensation Committee.
The Chairman and the CEO had variable components to their compensation in the
past financial year based on certain performance criteria. With respect to
compensation for executive officers other than the Chairman, the CEO or the
President and COO, the Board of Directors reviews a compensation proposal
prepared by the CEO and the President and COO, and approved by the Compensation
Committee.

Objectives

      The primary objectives of the Company's executive compensation program are
to enable the Company to attract, motivate and retain outstanding individuals
and to align their success with that of the Company's shareholders through the
achievement of strategic corporate objectives and creation of shareholder value.
The level of compensation paid to an individual is based on the individual's
overall experience, responsibility and performance. The Company's executive
compensation program consists of a base salary, performance bonuses and stock
options. The Company furnishes other benefits to certain of its officers and
other employees.

or a Vice-Chairman of the board of directors, where such person performed the
functions of such office on a full-time basis; the President; any Vice-President
in charge of a principal business unit such as sales, finance or production; any
officer or key employee of the Company or of a subsidiary of the Company, and
any other person who performed a policy-making function in respect of the
Company.

Employment Agreements

      The Company has entered into employment agreements with each of its Named
Executive Officers (as hereinafter defined), providing for base salaries and
incentive plan bonuses as approved by the Board of Directors of the Company,
medical and dental benefits and reimbursement for certain expenses approved by
the Company.

Termination Arrangements

      The Company may terminate any of its officers for cause without any
payment of any kind of compensation, except for such compensation earned to the

the date of termination and a lump sum termination payment equal to their base
annual salary. Any officer may terminate their employment with the Company at
any time by giving four weeks written notice to the Board of Directors of the
Company. In the event of a takeover or change of control of the Company, any
officer of the Company may elect to terminate their employment and receive, in
addition to compensation earned to the date of his termination, a lump sum
payment equal to their annual base salary. If an officer is terminated by the
Company within two years after such takeover or change in control, such officer
is also entitled to compensation earned to the date of termination and a
lump-sum payment equal to his annual base salary.

place for the Named Executive Officers or any other officers.

Report of Independent Auditors

To the Board of Directors and Shareholders of
MDSI Mobile Data Solutions Inc.

We have audited the accompanying consolidated balance sheets of MDSI Mobile Data
Solutions Inc. as at December 31, 1999 and 1998 and the related consolidated
statements of operations, stockholders' equity and cash flows for the each of
the years in the three year 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 conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform an audit to obtain reasonable assurance whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, these consolidated financial statements present fairly, in all
material respects, the financial position of the Company as at December 31, 1999
and 1998 and the results of its operations and cash flows for each of the years
in the three year period ended December 31, 1999 in conformity with accounting
principles generally accepted in the United States of America.

SUPPLEMENTAL DISCLOSURE OF NON CASH INVESTING AND FINANCING ACTIVITIES

In February 1999, the Company adopted a plan to dispose of the Transportation
Business Unit which was completed on June 1, 1999. The Company disposed of the
Transportation Business Unit for proceeds of $5,532,730 comprised of common
shares representing an 11% interest in Digital Dispatch Systems, Inc. and a

bearing an interest rate of 8% per annum.

During the year ended December 31, 1998, the Company leased certain computer
equipment to a customer. The transaction was accounted for as a sales-type lease
with a discounted present value of $1,406,367 at December 31,1998. The equipment
purchase was financed by capital lease, which had a balance of $1,199,214 at
December 31, 1998.

During the year ended December 31, 1997, the Company issued 280,000 common
shares and 280,000 common share purchase warrants on the exercise of 280,000
special warrants without additional consideration.

                 Notes to the Consolidated Financial Statements
              For the years ended December 31, 1999, 1998 and 1997
                         (Expressed in Canadian dollars)

1.    SIGNIFICANT ACCOUNTING POLICIES

      These financial statements have been prepared in accordance with generally
      accepted accounting principles in the United States and reflect the
      following significant accounting policies:

      (a)   Basis of presentation

            These consolidated financial statements include the accounts of the
            Company and its wholly-owned subsidiaries. All intercompany balances
            and transactions have been eliminated.

      (b)   Nature of operations

            The Company develops, markets and supports wireless mobile data
            communication software products.

      (c)   Research and development

            Research and development costs related to software are expensed as
            incurred unless a project meets the specified criteria for
            capitalization in accordance with Statement of Financial Accounting
            Standard No. 86 Accounting for the Costs of Computer Software to be
            Sold, Leased or Otherwise Marketed. Acquired research and
            development costs related to software are charged to earnings on
            acquisition if there is no alternative future use and technological
            feasibility has not been established.

      (d)   Revenue recognition

            Statement of Position 97-2 (Software Revenue Recognition) (SOP
            97-2), was issued in October 1997 by the American Institute of
            Certified Public Accountants (AICPA) and was amended by the
            Statement of Position 98-4 (SOP 98-4). The Company adopted SOP 97-2
            effective for the Company's year ended December 31 1998. Based upon
            our interpretation of SOP 97-2 and SOP 98-4, the Company believes
            its current revenue recognition policies and practices are
            consistent with SOP 97-2 and SOP 98-4. Additionally, the AICPA
            issued SOP 98-9, which provides certain amendments to SOP 97-2,
            which is effective for transactions entered into beginning July 1,
            1999. This pronouncement has not materially impacted the Company's
            revenue recognition practices.

            The Company's revenue is derived primarily from the following
            sources:

            (i)   Software and services

                  Revenue related to software and services, including software
                  licenses, is generally recognized on a percentage of
                  completion basis, representing costs incurred relative to
                  total estimated costs. Where the Company has contracted to
                  deliver software without significant production, modification
                  or customization required, revenue is recognized upon delivery
                  if the fee is determinable and there is reasonable assurance
                  of collection. Provisions for estimated losses on contracts
                  are recorded when identifiable.

            (ii)  Third party products and services and terminals and
                  infrastructure

                  Revenue from sales of third party products and services and
                  terminals and infrastructure is recognized on delivery of
                  products.

            (iii) Maintenance and support

                  Revenue related to maintenance agreements for supporting and
                  maintaining the Company's products are recognized rateably
                  over the term of the agreement, generally one year.

                 Notes to the Consolidated Financial Statements
              For the years ended December 31, 1999, 1998 and 1997
                         (Expressed in Canadian dollars)

1.    SIGNIFICANT ACCOUNTING POLICIES (Continued)

      (e)   Capital assets

            Capital assets are recorded at cost. Depreciation is charged to
            operations over the estimated useful lives of the assets as follows:

            Computer hardware and software  30% declining balance
            Furniture and fixtures          20% declining balance
            Leasehold improvements          lesser of lease term or useful life,
                                            generally five years

            The carrying value of capital assets is reviewed on a regular basis
            for any permanent impairment in value. An impairment loss would be
            recognized when estimates of future cash flows expected to result
            from the use of an asset and its eventual disposition are less than
            it carrying amount. To date, no such impairment has been indicated.

      (f)   Goodwill

            Goodwill arising on the acquisition of Alliance is amortized on a
            straight-line basis over ten years. Management regularly reviews the
            carrying value of goodwill based upon expected future cash flows. To
            date, no impairment has been indicated.

      (g)   Foreign exchange

            The accounts of the Company and its foreign subsidiaries are
            expressed in Canadian dollars, its functional currency. Monetary
            assets and liabilities denominated in foreign currencies are
            translated at the rate in effect at the balance sheet date. Other
            balance sheet items and revenues and expenses are translated at the
            rates prevailing on the respective transaction dates. Translation
            gains and losses relating to current monetary items and revenue and
            expenses denominated in foreign currencies are included in income.

      (h)   Income taxes

            The Company accounts for income taxes using the asset and liability
            method. Under this method, deferred income taxes are recorded for
            the temporary differences between the financial reporting basis and
            tax basis of the Company's assets and liabilities. These deferred
            taxes are measured by the provisions of currently enacted tax laws.
            Management believes that it is more likely than not that the Company
            will generate sufficient taxable income to allow the realization of
            the recorded deferred tax assets.

            (i)   Investments

                  The Company accounts for investments on a cost basis, Any
                  impairment in value that is determined to be other than
                  temporary is charged to earnings.

            (j)   Earnings (loss) per common share

                  Basic earnings per share is computed by dividing net income
                  (loss) available to common shareholders by the weighted
                  average number of common shares outstanding for the period.
                  Diluted earnings per share reflects the potential dilution of
                  securities by including other common share equivalents in the
                  weighted average number of common shares outstanding for a
                  period, if dilutive. Common equivalent shares consist of
                  common shares issuable upon the conversion of the special
                  warrants (using the if-converted method) and incremental
                  shares issuable upon the exercise of stock options and share
                  purchase warrants (using the treasury stock method).

1.    SIGNIFICANT ACCOUNTING POLICIES (Continued)

      (k)   Use of estimates

            The preparation of financial statements in conformity with generally
            accepted accounting principles requires management to make estimates
            and assumptions that affect the reported amounts of assets and
            liabilities and disclosure of contingent assets and liabilities at
            the date of the financial statements and the reported amounts of
            revenues and expenses during the reporting periods. Estimates are
            used for, but not limited to, the accounting for doubtful accounts,
            amortization, determination of net recoverable value of assets,
            revenue recognized on long-term contracts, taxes and contingencies.
            Actual results could differ from those estimates.

      (l)   Derivatives

            From time to time the Company may attempt to hedge its position with
            respect to currency fluctuations on specific contracts. This is
            generally accomplished by entering into forward contracts. Related
            costs are realized as the forward contracts are settled. The Company
            had forward contracts as outlined in note 11(c).

      (m)   Stock-based compensation

            The Company accounts for stock-based compensation using the
            intrinsic value based method whereby compensation cost is recorded
            for the excess, if any, of the quoted market price of the common
            share over the exercise price at the date granted for all common
            stock options. As at December 31, 1999, no compensation cost has
            been recorded for any period under this method.

            The following pro forma financial information presents the net
            income (loss) for the year and income (loss) per common share had
            the Company adopted Statement of Financial Accounting Standard No.
            123 (SFAS 123) Accounting for Stock-based Compensation.

</TABLE>

            Using the fair value method for stock-based compensation, additional
            compensation costs of approximately $5,127,211 would have been
            recorded for the year ended December 31, 1999 (1998 - $3,368,111 and
            1997 - $1,710,995, respectively). This amount is determined using an
            option pricing model assuming no dividends are to be paid, an
            average vesting period of three years, a weighted average annualized
            volatility of the Company's share price of 65.14% (1998 - 56.03% and
            1997 - 43.93% respectively) and a weighted average annualized risk
            free interest rate at 5.00% (1998 - 5.00% and 1997 - 5.00%
            respectively).

      (n)   Comprehensive income

            SFAS 130, Reporting Comprehensive Income, establishes standards for
            the reporting and display of comprehensive income and its components
            in a full set of general purpose financial statements.
            Reclassification of financial statements for earlier periods
            presented is required. As the Company's operations do not generate
            any other comprehensive items, the adoption of this standard has no
            affect on the Company's financial statements.

      (o)   Segmented information

            SFAS 131, Disclosures About Segments of an Enterprise and Related
            Information, establishes new standards for the reporting of
            segmented information in annual financial statements and requires
            the reporting of certain selected segmented information on interim
            reports to shareholders. The Company adopted SFAS 131 for the year
            ended December 31, 1997 (note 12).

1.    SIGNIFICANT ACCOUNTING POLICIES (Continued

      (p)   Accounting for derivative instruments and hedging activities

            In June 1998, the Financial Accounting Standards Board issued
            Statement No. 133 (SFAS 133), Accounting for Derivative Instruments
            and Hedging Activities, which standardizes the accounting for
            derivative instruments and is effective for all fiscal quarters of
            all fiscal years beginning after June 15, 1999. The Company
            anticipates that the adoption of this statement, which requires the
            accounting recognition of derivatives at fair value, will not have a
            significant effect on the Company's financial position or results of
            operations. SFAS 137 defers the date of implementation to June 15,
            2000. The impact on the Company's financial statements has not been
            determined.

      (q)   Cash and cash equivalents

            Cash and cash equivalents consist of cash on hand, deposits in banks
            and highly liquid investments with an original maturity of three
            months or less.

2.    ACQUISITIONS

      Alliance Systems Incorporated

      On April 17, 1997, the Company entered into an agreement to acquire all of
      the issued and outstanding shares of Alliance Systems Incorporated
      ("Alliance") for $9,116,828, consisting of 347,750 common shares and
      US$1,582,088 ($2,188,750) including cash of US$1,367,869 ($1,892,426) and
      US$214,219 ($296,324) of unsecured promissory notes which bear interest at
      6.07% and matured on January 1, 1999. The acquisition was completed July
      1, 1997 and the common shares were issued at that date. Alliance, based in
      Itasca, Illinois, is a supplier of mobile workforce management solutions
      to the utility, public safety and cable market sectors.

      This transaction has been accounted for using the purchase method and the
      purchase price has been allocated to the estimated fair value of net
      assets acquired as follows:

      Estimated fair value of net assets acquired:

      (b)   Stock purchase plan

            The Company has established a voluntary stock compensation
            arrangement for its full and part-time employees to purchase common
            shares of the Company by way of payroll deductions for a maximum of
            $10,000 for each employee per year. The subscription price of common
            shares purchased under the Stock Purchase Plan is determined based
            upon a weighted average market price of the Company's common shares
            each quarter, less 15%. The Company has reserved 100,000 common
            shares for issuance pursuant to the Stock Purchase Plan. During the
            year ended December 31, 1999, 28,144 common shares were issued under
            this Plan.

      (c)   Special warrants and share purchase warrants

            In June 1996, the Company issued 280,000 special warrants through a
            private placement for net proceeds of $3,925,100 (net of issue costs
            of $30,000). Each special warrant was exchangeable, without further
            payment or additional consideration, into one common share and one
            share purchase warrant. During the year ended December 31, 1997,
            280,000 common shares and 280,000 share purchase warrants were
            issued on the conversion of special warrants. During the year ended
            December 31, 1998, 258,000 share purchase warrants were exercised to
            purchase 51,600 common shares for proceeds of $731,400.

            sale and issue of 575,000 common shares at a price of $27.75 per
            share for net proceeds of $14,735,937 (net of offering costs of
            $1,220,313).

      (e)   Alliance employee stock ownership plan

            Prior to the Company's acquisition of Alliance, the Alliance
            employees participated in an employee stock ownership plan (the
            ESOP). Upon the Company's acquisition of Alliance (note 2), the
            remaining unallocated shares held by the ESOP were allocated to
            employees. At December 31, 1999, 99,079 shares of the Company were
            held by the ESOP of which all have vested and are in the process of
            being distributed.

      (f)   Shareholder rights plan

            At the Annual General Meeting on May 6, 1999, the Company's
            shareholders' approved the adoption of a Shareholder Rights Plan,
            similar to those adopted by other Canadian companies. Under the
            terms of the Plan, rights are attached to the common shares of the
            Company. These rights become marketable and exercisable only after
            certain specified events related to the acquisition of, or
            announcement of an intention to acquire 20% or more of the
            outstanding common shares of the Company.

            Rent expense for the year ended December 31, 1999 in respect of

      (b)   Line and letters of credit

            The Company has an operating line of credit with a Canadian
            commercial bank to borrow up to $8,000,000 which bears interest at
            prime plus 0.5%. As at December 31, 1999, the Company was not
            utilizing the operating line of credit. The Company has provided, as
            performance bonds, an irrevocable revolving letter of credit in the

            Belgian Franc 3,060,000 maturing August 30, 2001 all with the same
            bank. The Company has pledged an amount equal to the letters of
            credit and guarantee against its operating line of credit as
            security.

      (c)   Foreign exchange forward contracts

            The Company has entered into a forward contract for Belgian Franc
            104,000,000 with a delivery date of October 31, 2000, a forward

            forward contract for GBP 180,000 with a delivery date of September
            29, 2000. All three foreign exchange forward exchange contracts have
            been accounted for as foreign currency hedges for specific foreign
            currency transactions.

12.   SEGMENTED INFORMATION

      Segmented information

      In 1997, the Company adopted the Financial Accounting Standards Board
      statement No.131 (SFAS 131) requiring disclosure of a company's business
      segments. In 1998, the Company reported two business segments - Field
      Service and Delivery based on the differing capabilities of the software
      and hardware platforms offered to customers. In February 1999, the
      Company's Board of Directors approved a plan to dispose of its Delivery
      Segment which was subsequently sold effective June 1, 1999 (note 16). As a
      result the Company now has only one business segment and therefore does
      not provide a detailed breakdown other than provided by its general
      purpose financial statements.

      Geographic information

      The Company earned revenue from sales to customers and has long-lived
      assets, including capital assets and goodwill, in the following geographic
      locations:

      10% of total revenue.

14.   FINANCIAL INSTRUMENTS

      The carrying value of cash and cash equivalents, accounts receivable,
      accounts payable, accrued liabilities, capital lease obligations and
      assets and liabilities from discontinued operations reflected in the
      balance sheets approximate their respective fair values.

      The Company estimates the fair value of its non-interest bearing long-term
      debt using discounted cash flows assuming a borrowing rate equal to the
      Bank of Canada rate plus 2%.

                          ========   ========   ========   ========

      The Company's revenues have historically been dependent on large contracts
      from a limited number of customers in the utility, telecommunications and
      cable sectors. However, as these customers are geographically dispersed
      and bad debts have not been significant, concentrations of credit risk are
      considered to be minimal.

15.   PROVISION FOR RESTRUCTURING

      During the year ended December 31, 1997, the Company recorded a one-time
      charge of $725,748 with respect to restructuring of certain operations.

16.   DISCONTINUED OPERATIONS

In February 1999, the Company's Board of Directors approved a plan for the sale
of the Transportation Business Unit which develops mobile workforce software for
the taxi, courier and roadside recovery markets. The disposition was completed
June 24, effective June 1, 1999, for proceeds of $5,532,730. The proceeds
comprise common shares representing an 11% interest in Digital Dispatch Systems
Inc., a supplier of dispatch systems to the taxi market, and an 8%, $500,000
promissory note due January 1, 2001.

For the year ended December 31, 1999, the Company recorded a one-time charge of
$5,852,786 concurrent with the decision to discontinue the Delivery segment of
the Company's business. Certain contracts were retained for completion during
the year 2000. The estimated cost to complete these contracts is included in the
one-time charge.

This business is accounted for as a discontinued operation and for reporting
purposes the results of operations, financial position and cash flow are
segregated from those of continuing operations for the current and prior
periods. The Company has included in the results of the discontinued operation,
the sale proceeds, the costs of disposition, the results of operations from the
measurement date to the disposal date and an estimate of the costs to complete
the remaining contract.

2. STATEMENT OF PURPOSE

2.1 Principal Purposes - The principal purposes of the Plan are to provide the
Company with the advantages of the incentive inherent in share ownership on the
part of employees, officers, directors, and consultants responsible for the
continued success of the Company; to create in such individuals a proprietary
interest in, and a greater concern for, the welfare and success of the Company;
to encourage such individuals to remain with the Company; and to attract new
employees, officers, directors and consultants to the Company.

2.2 ISOs and Non-ISOs - Under this Plan, the Company may grant either ISOs or
Non-ISOs. Each ISO granted hereunder is intended to constitute an "incentive
stock option", for the purposes of section 422 of the Code, and this Plan and
each such ISO is intended to comply with all of the requirements of Section 422
of the Code and of all other provisions of the Code applicable to incentive
stock options and to plans issuing the same. Each Non-ISO granted hereunder is
intended to constitute an Option that is not an "incentive stock option" for the
purposes of section 422 of the Code, and that does not comply with the
requirements of Section 422 of the Code.

2.3 Benefit to Shareholders - The Plan is expected to benefit shareholders by
enabling the Company to attract and retain personnel of the highest caliber by
offering such personnel an opportunity to share in any increase in value of the
Shares resulting from their efforts.

3. ADMINISTRATION

3.1 Board or Committee - The Plan shall be administered by the Board or by a
Committee appointed in accordance with Section 3.2 or 3.5(b) below.

3.2 Appointment of Committee - The Board may at any time appoint a Committee,
consisting of not less than two of its members, to administer the Plan on behalf
of the Board in accordance with such terms and conditions as the Board may
prescribe, consistent with this Plan. Once appointed, the Committee shall
continue to serve until otherwise directed by the Board. From time to time, the
Board may increase the size of the Committee and appoint additional members,
remove members (with or without cause) and appoint new members in their place,
fill vacancies however caused, or remove all members of the Committee and
thereafter directly administer the Plan.

3.3 Quorum and Voting - A majority of the members of the Committee shall
constitute a quorum, and, subject to the limitations in this Section 3, all
actions of the Committee shall require the affirmative vote of members who
constitute a majority of such quorum. No member of the Committee who is a
director to whom an Option may be granted may participate in the decision to
grant such Option (but any such member may be counted in determining the

<PAGE>

existence of a quorum at any meeting of the Committee in which action is taken
with respect to the granting of an Option to him).

3.4 Administration of Plan upon Registration of Equity Securities -
Notwithstanding the foregoing provisions of this Section 3, in the event the
Company is or becomes subject to the provisions of Section 16 of the Exchange
Act, the Board shall attempt to provide for administration of the Plan, insofar
as it relates to the participation of officers, directors or stockholders of the
Company who are subject to the reporting and liability provisions of Section 16
of the Exchange Act, in a manner which shall qualify the grant, exercise,
expiration or surrender of Options under this Plan for the treatment afforded by
Securities and Exchange Commission Rule 16b-3, as amended from time to time, or
any successor rule or regulatory requirements.

3.5 Powers of Committee - Any Committee appointed under Section 3.2 or 3.4 above
shall have the authority to do the following:

      (a)   administer the Plan in accordance with its terms;

      (b)   determine all questions arising in connection with the
            administration, interpretation, and application of the Plan,
            including all questions relating to the value of the Shares;

      (c)   correct any defect, supply any information or reconcile any
            inconsistency in the Plan in such manner and to such extent as shall
            be deemed necessary or advisable to carry out the purposes of the
            Plan;

      (d)   prescribe, amend and rescind rules and regulations relating to the
            administration of the Plan;

      (e)   determine the duration and purpose of leaves of absence from
            employment which may be granted to Optionees without constituting a
            termination of employment for purposes of the Plan;

      (f)   do the following with respect to the granting of Options:

            (i)   determine the employees, officers, directors or consultants to
                  whom Options shall be granted, based on the eligibility
                  criteria set out in this Plan,

            (ii)  determine whether such Options shall be ISOs or Non-ISOs,

            (iii) determine the terms and provisions of the Option Agreement
                  which shall be entered into with each Optionee (which need not
                  be identical with the terms of any other Option Agreement),

            (iv)  amend the terms and provisions of an Option Agreement,
                  provided the Committee obtains:

                  A.    the consent of the Optionee; and

                  B.    the approval of any stock exchange on which the Company
                        is listed,

            (v)   determine when Options shall be granted,

            (vi)  determine the number of Shares subject to each Option, and

      (g)   make all other determinations necessary or advisable for
            administration of the Plan.

3.6 Obtain Regulatory Approvals - In administering this Plan, the Committee will
obtain any regulatory approvals which may be required pursuant to applicable
securities laws or the rules of any stock exchange or over the counter market on
which the Shares are listed.

<PAGE>

3.7 Administration by Committee - The Committee's exercise of the authority set
out in Section 3.5 shall be consistent with the intent that ISOs issued under
the Plan be qualified under the terms of Section 422 of the Code, and that
Non-ISOs shall not be so qualified. All determinations made by the Committee in
good faith on matters referred to in Section 3.5 shall be final, conclusive and
binding upon all Persons. The Committee shall have all powers necessary or
appropriate to accomplish its duties under this Plan. In addition, the
Committee's administration of the Plan shall in all respects be consistent with
the policies and rules of any stock exchange or over the counter market on which
the Shares are listed.

4. ELIGIBILITY

4.1 Eligibility for ISOs - ISOs may be granted to any employee of the Company or
any Related Company, including directors or officers who are employees of the
Company or any Related Company. An Optionee who is not an employee of the
Company or any Related Company is not eligible to receive an ISO under the Plan.

4.2 Eligibility for Non-ISOs - Non-ISOs may be granted to any employee, officer,
director or consultant of the Company or any Related Company.

4.3 No Violation of Securities Laws - No Option shall be granted to any Optionee
unless the Committee has determined that the grant of such Option and the
exercise thereof by the Optionee will not violate the securities law of the
jurisdiction in which the Optionee resides.

5. SHARES SUBJECT TO THE PLAN

5.1 Number of Shares - The Committee, from time to time, may grant Options to
purchase an aggregate of up to 2,100,000 Shares, subject to regulatory approval,
to be made available from authorized, but unissued, Shares. In calculating the
foregoing 2,100,000 Shares, the Committee shall include all Shares subject to
options outstanding prior to the Effective Date of the Plan, which as at the
Effective Date, comprises 1,569,249 Shares. The maximum number of 2,100,000
Shares shall be adjusted, where necessary, to take account of the events
referred to in Section 11 hereof.

5.2 Decrease in Number of Shares Subject to Plan - Upon exercise of an Option,
the number of Shares thereafter available under the Plan and under the Option
shall decrease by the number of Shares as to which the Option was exercised.

5.3 Expiry of Option - If an Option expires or terminates for any reason without
having been exercised in full, the unpurchased Shares subject thereto shall
again be available for the purposes of the Plan.

5.4 Reservation of Shares - The Company will at all times reserve for issuance
and keep available such number of Shares as shall be sufficient to satisfy the
requirements of the Plan.

      (b)   the number of Shares subject to purchase pursuant to such Option,

                  voting power of all classes of shares of the Company, the Term
                  of the Option shall not exceed five years;

      (e)   the Option Price, provided that:

            (i)   the Option Price shall not be less than the Fair Market Value
                  of the Shares on the Date of Grant; and

            (ii)  if an ISO Option is granted to an Optionee who on the Date of
                  Grant beneficially owns more than 10% of the total combined
                  voting power of all classes of shares of the Company or a
                  Related Company, then the Option Price shall be at least 110%
                  of the Fair Market Value of the Shares on the Date of Grant;

      (f)   any vesting schedule upon which the exercise of an Option is
            contingent; provided that the Committee shall have complete
            discretion with respect to the terms of any such vesting schedule,
            including, without limitation, discretion to:

            (i)   allow full and immediate vesting upon the grant of such
                  Option,

            (ii)  to permit partial vesting in stated percentage amounts based
                  on the length of the Term of such Option, and

            (iii) to permit full vesting after a stated period of time has
                  passed from the Date of Grant; and

      (g)   such other terms and conditions as the Committee deems advisable and
            are consistent with the purposes of this Plan.

Amendments to Option Agreements are subject to regulatory approval, if required.

6.2 No Grant After Ten Years From Effective Date - No Option shall be granted
under the Plan later than ten years from the Effective Date of the Plan. Except
as expressly provided herein, nothing contained in this Plan shall require that
the terms and conditions of Options granted under the Plan be uniform.

6.3 No Disposition for Six Months - An Optionee who is subject to Section 16 of
the Exchange Act shall not make any disposition, as that term is used by Rule
16b-3 under the Exchange Act, of any Shares issued upon exercise of an Option
unless at least six months has elapsed between the Date of Grant of the Option
and the date of disposition of the Shares issued upon exercise of such Option.

7. LIMITATION ON GRANTS OF OPTIONS

7.1 Non-ISO if Exceed $100,000 (U.S.) - If the aggregate Fair Market Value of:

      (a)   Shares underlying Options which are ISOs which have been granted to
            an Optionee under this Plan, and

      (b)   Shares underlying incentive stock options which have been granted to
            such Optionee under any other plan of the Company or any Related
            Company,

<PAGE>

which are exercisable for the first time during a calendar year, exceeds
$100,000 (U.S.), as such amount may be adjusted from time to time under Section
422(d) of the Code, then, to the extent of such excess, such Options shall be
treated as Non-ISOs.

7.2 ISO Optionee Owning Greater Than 10% of Voting Securities - The Committee
may grant an ISO to an employee of the Company or any Related Company who, at
the Date of Grant, owns securities of the Company or any Related Company
representing more than 10% of the total combined voting power of all classes of
shares of the Company or any Related Company, only if:

      (a)   the Option Price is at least 110% of the Fair Market Value of the
            Shares at the Date of Grant; and

      (b)   the Term is five years or less.

8. EXERCISE OF OPTION

8.1 Method of Exercise - Subject to any limitations or conditions imposed upon
an Optionee pursuant to the Option Agreement or Section 6 hereof, an Optionee
may exercise an Option by giving written notice thereof to the Company at its
principal place of business.

8.2 Payment of Option Price - The notice described in Section 8.1 shall be
accompanied by full payment of the aggregate Option Price to the extent the
Option is so exercised, and full payment of any amounts the Company determines
must be withheld for tax purposes from the Optionee pursuant to the Option
Agreement. Such payment shall be:

      (a)   in lawful money (Canadian funds) by cheque;

      (b)   at the discretion of the Committee and if such form of payment is
            permitted under the corporate laws then governing the Company, by
            delivery of the Optionee's personal recourse note bearing interest
            at a rate deemed appropriate by the Committee;

      (c)   at the discretion of the Committee, and subject to all applicable
            securities laws, through delivery by the Optionee and/or withholding
            by the Company, of Shares having a market value as of the date of
            exercise equal to the cash exercise price of the Option plus any
            amounts that the Company determines must be withheld from the
            Optionee for U.S. or Canadian tax purposes. The market value of each
            of the Shares on the date of delivery shall be determined in good
            faith by the Committee, which determination shall be binding for all
            purposes hereunder; or

      (d)   at the discretion of the Committee, by any combination of the
            consideration contemplated by Sections 8.2(a) to 8.2(c) above.

8.3 Issuance of Certificates - As soon as practicable after exercise of an
Option in accordance with Sections 8.1 and 8.2 hereof, the Company shall issue a
certificate or certificates evidencing the Shares with respect to which the
Option has been exercised. Until the issuance of such certificate or
certificates, no right to vote or receive dividends or any other rights as a
shareholder shall exist with respect to such Shares, notwithstanding the
exercise of the Option. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the certificate is issued, except
as provided by Section 11 hereof.

9. TRANSFERABILITY OF OPTIONS

9.1 Non-Transferable - Except as provided otherwise in this Section 9, Options
are non-assignable and non-transferable.

9.2 Death of Optionee - If the employment of an Optionee as an employee or
consultant of the Company or any Related Company, or the position of an Optionee
as a director or officer of the Company or any Related Company, terminates as a
result of his or her death, any Options held by such Optionee shall pass to the
Qualified Successor of the Optionee, and

      (a)   in the case of an ISO, shall be exercisable by the Qualified
            Successor for a period of six months following such death, and

      (b)   in the case of a Non-ISO, shall be exercisable by the Qualified
            Successor for a period of 12 months following such death,

provided that in no case shall the Term of the Option extend beyond 10 years
from the Date of Grant.

9.3 Disability of Optionee - If the employment of an Optionee as an employee or
consultant of the Company or any Related Company, or the position of an Optionee
as a director or officer of the Company or any Related Company, is terminated by
the Company or any Related Company by reason of such Optionee's Disability, any
Option held by such Optionee that could have been exercised immediately prior to
such termination of service shall be exercisable by such Optionee, or by his
Guardian, for a period of one year following the termination of service of such
Optionee.

9.4 Disability and Death of Optionee - If an Optionee who has ceased to be
employed by the Company or any Related Company by reason of such Optionee's
Disability dies within six months after the termination of such employment, any
Option held by such Optionee that could have been exercised immediately prior to
his or her death shall pass to the Qualified Successor of such Optionee, and
shall be exercisable by the Qualified Successor:

      (a)   in the case of an ISO, for a period of six months following the
            death of such Optionee, and

      (b)   in the case of a Non-ISO, for a period of 12 months following the
            death of such Optionee,

provided that in no case shall the Term of the Option extend beyond 10 years
from the Date of Grant.

9.7 Deemed Non-Interruption of Employment - Employment shall be deemed to
continue intact during any military or sick leave or other bona fide leave of
absence if the period of such leave does not exceed 90 days or, if longer, for
so long as the Optionee's right to reemployment with the Company or any Related
Company is guaranteed either by statute or by contract. If the period of such
leave exceeds 90 days and the Optionee's reemployment is not so guaranteed, then
his or her employment shall be deemed to have terminated on the ninety-first day
of such leave.

10. TERMINATION OF OPTIONS

10.1 Termination of Options - To the extent not earlier exercised or terminated
in accordance with section 9 above, an Option shall terminate at the earliest of
the following dates:

      (a)   the termination date specified for such Option in the Option

<PAGE>

      (b)   where the Optionee's position as an employee, consultant or director
            of the Company or any Related Company is terminated for just cause,
            the date of such termination for just cause;

      (c)   where the Optionee's position as an employee, consultant, officer or
            director of the Company or any Related Company terminates for a
            reason other than the Optionee's Disability, death, or termination
            for just cause, 30 days after such date of termination, or upon the
            Optionee making written application to the Committee and receiving
            the written consent of the Committee, which consent may be given at
            the discretion of the Committee, no later than the original expiry
            date of such Option when it was granted;

      (d)   the date of any sale, transfer, assignment or hypothecation, or any
            attempted sale, transfer, assignment or hypothecation, of such
            Option in violation of Section 9.1 above; and

      (e)   the date specified in Section 11.2 below for such termination in the
            event of a Terminating Event.

10.2 Lapsed Options - If Options are surrendered, terminated or expire without
being exercised in whole or in part, new Options may be granted covering the
Shares not purchased under such lapsed Options. If an Option has been
surrendered in connection with the regranting of a new Option to the same
Optionee on different terms than the original Option granted to such Optionee,
then the new Option is subject to approval of the stock exchange on which the
Shares are listed.

11. ADJUSTMENTS TO OPTIONS

11.1 Alteration in Capital Structure - If there is a material alteration in the
capital structure of the Company resulting from a recapitalization, stock split,
reverse stock split, stock dividend, or otherwise, the Committee shall make such
adjustments to this Plan and to the Options then outstanding under this Plan as
the Committee determines to be appropriate and equitable under the
circumstances, so that the proportionate interest of the holder of each such
Option shall, to the extent practicable, be maintained as before the occurrence
of such event. Such adjustments may include, without limitation (a) a change in
the number or kind of shares of the Company covered by such Options, and (b) a
change in the Option Price payable per share; provided, however, that the
aggregate Option Price applicable to the unexercised portion of existing Options
shall not be altered, it being intended that any adjustments made with respect
to such Options shall apply only to the price per share and the number of shares
subject thereto. For purposes of this Section 11.1, neither (i) the issuance of
additional shares of stock of the Company in exchange for adequate consideration
(including services), nor (ii) the conversion of outstanding preferred shares of
the Company into Shares shall be deemed to be material alterations of the
capital structure of the Company. If the Committee determines that the nature of
a material alteration in the capital structure of the Company is such that it is
not practical or feasible to make appropriate adjustments to this Plan or to the
Options granted hereunder, such event shall be deemed a Terminating Event for
the purposes of this Plan.

11.2 Terminating Events - Subject to Section 11.3, all Options granted under the
Plan shall terminate upon the occurrence of a Terminating Event.

11.3 Notice of Terminating Event - The Committee shall give notice to Optionees
not less than thirty days prior to the consummation of a Terminating Event. Upon
the giving of such notice, all Options granted under the Plan shall become
immediately exercisable, notwithstanding any contingent vesting provision to
which such Options may have otherwise been subject.

11.4 Corporate Reorganization - In the event of a reorganization as defined in
this Section 11.4 in which the Company is not the surviving or acquiring
corporation, or in which the Company is or becomes a wholly-owned subsidiary of
another corporation after the effective date of the reorganization, then unless
provision is made by the acquiring corporation for the assumption of each Option
granted under this Plan, or the substitution of an option therefor, such that no
Modification of any such Option occurs, all Options granted under this Plan
shall terminate and such event shall be deemed a Terminating Event. For purposes
of this Section 11.4, reorganization shall mean any statutory merger, statutory
consolidation, sale of all or substantially all of the assets of the Company, or
sale, pursuant to an agreement with the Company, of securities of the Company
pursuant to which the Company is or becomes a wholly-owned subsidiary of another
corporation after the effective date of the reorganization.

<PAGE>

11.5 Acceleration on Change of Control - Upon a Change in Control, all Options
shall become immediately exercisable, notwithstanding any contingent vesting
provisions to which such Options may have otherwise been subject.

11.6 Acceleration of Date of Exercise - The Committee shall have the right to
accelerate the date of exercise of any installment of any Option; provided that,
without the consent of the Optionee with respect to any Option, the Committee
shall not accelerate the date of any installment of any Option granted to an
employee as an ISO (and not previously converted into a Non-ISO pursuant to
Section 13 below) if such acceleration would violate the annual vesting
limitation contained in Section 422(d) of the Code, as described in Section 7.1
above.

11.7 Determinations to be Made By Committee - Adjustments and determinations
under this Section 11 shall be made by the Committee, whose decisions as to the
adjustments or determination which shall be made, and the extent thereof, shall
be final, binding, and conclusive.

11.8 Effect of a Take-over If a bona fide offer (the "Offer") for Shares is made
to an Optionee or to shareholders generally or to a class of shareholders which
includes the Optionee, which Offer, constitutes a take-over bid within the
meaning of section 89(1) of the Ontario Securities Act, as amended from time to
time, the Company shall, immediately upon receipt of notice of the Offer, notify
each Optionee of full particulars of the Offer, whereupon any Option held by an
Optionee may be exercised in whole or in part by the Optionee so as to permit
the Optionee to tender the Shares received upon such exercise (the "Optioned
Shares") to the Offer. If:

      (a)   the Offer is not completed within the time specified therein; or

      (b)   all of the Optioned Shares tendered by the Optionee pursuant to the
            Offer are not taken up and paid for by the offeror pursuant thereto;

the Optioned Share or, in the case of clause (b) above, the optioned Shares that
are not taken up and paid for, may be returned by the Optionee to the Company
and reinstated as authorized but unissued shares and with respect to such
returned Optioned Shares, the Option shall be reinstated as if it had not been
exercised. If any Optioned Shares are returned to the Company under this
Section, the Company shall refund the exercise price to the Optionee for such
Optioned Shares.

12. TERMINATION AND AMENDMENT OF PLAN

12.1 Termination of Plan - Unless earlier terminated as provided in Section 11
above or in Section 12.2 below, the Plan shall terminate on, and no Option shall
be granted under the Plan on or after, the date which is ten years from the
Effective Date of the Plan.

12.2 Power of Committee to Terminate or Amend Plan - Subject to the approval of
any stock exchange on which the Company is listed, the Committee may terminate,
suspend or amend the terms of the Plan; provided, however, that, except as
provided in Section 11 above, the Committee may not do any of the following
without obtaining, within 12 months either before or after the Committee's
adoption of a resolution authorizing such action, approval by the affirmative
votes of the holders of a majority of the voting securities of the Company
present, or represented, and entitled to vote at a meeting duly held in
accordance with the applicable corporate laws, or by the written consent of the
holders of a majority of the securities of the Company entitled to vote:

      (a)   increase the aggregate number of Shares which may be issued under
            the Plan;

      (b)   materially modify the requirements as to eligibility for
            participation in the Plan, or change the designation of the
            employees or class of employees eligible to receive ISOs under the
            Plan;

      (c)   materially increase the benefits accruing to participants under the
            Plan; or

      (d)   make any change in the terms of the Plan that would cause the ISOs
            granted hereunder to lose their qualification as "incentive stock
            options" under Section 422 of the Code;

<PAGE>

however, the Committee may amend the terms of the Plan to comply with the
requirements of any applicable regulatory authority, without obtaining the
approval of its shareholders.

12.3 No Grant During Suspension of Plan - No Option may be granted during any
suspension, or after termination, of the Plan. Amendment, suspension or
termination of the Plan shall not, without the consent of the Optionee, alter or
impair any rights or obligations under any Option previously granted.

13. CONVERSION OF ISOs INTO NON-ISOs

13.1 Conversion of ISOs into Non-ISOs - At the written request of any ISO
Optionee, the Committee may in its discretion take such actions as may be
necessary to convert such Optionee's ISOs (or any installments or portions of
installments thereof) that have not been exercised on the date of conversion
into Non-ISOs at any time prior to the expiration of such ISOs, regardless of
whether the Optionee is an employee of the Company or a Related Company at the
time of such conversion. Such actions include, but shall not be limited to,
extending the exercise period of such ISOs, provided, however, that such
exercise period shall in no event exceed 10 years following the Date of Grant
without approval of The Toronto Stock Exchange. At the time of such conversion,
the Committee, with the consent of the Optionee, may impose such conditions on
the exercise of the resulting Non-ISOs as the Committee in its discretion may
determine, provided that such conditions are consistent with this Plan. Nothing
in the Plan shall be deemed to give any Optionee the right to have such
Optionee's ISOs converted into Non-ISOs, and no such conversion shall occur
until and unless the Committee takes appropriate action. The Committee, with the
consent of the Optionee, may also terminate any portion of any ISO that has not
been exercised at the time of such conversion.

14. CONDITIONS PRECEDENT TO ISSUANCE OF SHARES

14.1 Compliance with Laws - Shares shall not be issued pursuant to the exercise
of any Option unless the Shares are fully paid and non-assessable and the
exercise of such Option and the issuance and delivery of such Shares comply with
all relevant provisions of law, including, without limitation, the United States
Securities Act of 1933, as amended, any applicable state or provincial
securities or corporate laws, the rules and regulations promulgated thereunder,
and the requirements of any stock exchange upon which the Shares may then be
listed or otherwise traded.

14.2 Representations by Optionee - As a condition precedent to the exercise of
any Option, the Company may require the Optionee to represent and warrant, at
the time of exercise, that the Shares are being purchased only for investment
and without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such representations and warranties are
required by any applicable law.

14.3 Regulatory Approval to Issuance of Shares - The Company's inability to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability with
respect to the failure to issue or sell such Shares.

15. USE OF PROCEEDS

15.1 Use of Proceeds - Proceeds from the sale of Shares pursuant to the Options
granted and exercised under the Plan shall constitute general funds of the
Company and shall be used for general corporate purposes.

16. NOTICES

notice is to be given, in which case notice shall be deemed to have been duly
given on the date of such service; telefaxed, in which case notice shall be
deemed to have been duly given on the date the telefax is sent; or mailed to the
party to whom notice is to be given, by first class mail, registered or
certified, return receipt requested, postage prepaid,

<PAGE>

and addressed to the party at his or its most recent known address, in which
case such notice shall be deemed to have been duly given on the tenth postal

interfere in any way with the right of the Company or any Related Company to
reduce such Optionee's compensation.

17.3 Binding Agreement - The provisions of this Plan and each Option Agreement
with an Optionee shall be binding upon such Optionee and the Qualified Successor
or Guardian of such Optionee.

singular shall include the plural, and vice versa, and references to a
particular gender shall include either or both genders.

17.5 Headings - The headings used in this Plan are for convenience of reference
only and shall not in any way affect or be used in interpreting any of the
provisions of this Plan.

      submitting the appropriate form provided by MDSI. If the Employee suspends
      Contributions, further Contributions shall not be permitted to the Plan
      until the start of the next quarter following the effective date of such
      suspension.

(d)   The MDSI Purchase Plan is intended to qualify as an "employee stock
      purchase plan" within the meaning of Section 423 of the United States
      Internal Revenue Code of 1986, as amended (the "Code"), and shall be
      interpreted and administered in accordance with that intent.

5. Method of Operation

In accordance with section 2(m) hereof, a Subscription Price for Shares will be
established by MDSI. An Employee wishing to participate in the Plan must enter
into a subscription agreement for Shares with MDSI prior to the start of the
year or the quarter, as the case may be. Employees may also enter into an annual
or balance of year subscription

<PAGE>

agreement with MDSI at the start of the MDSI fiscal year or any quarter,
provided that the subscription price for the Shares subscribed will be
determined at the start of each quarter.

Notwithstanding any other provision to the contrary, no Employee shall be
permitted to subscribe for any shares under the MDSI Purchase Plan if such
Employee, immediately after such subscription, owns shares that account for
(including all Shares that may be purchased under outstanding subscriptions
under the MDSI Purchase Plan and any other outstanding options to purchase
shares) five percent (5%) or more of the total combined voting power or value of
all classes of shares of MDSI or its subsidiaries, taking into account the stock
ownership rules in Code Section 424(d).

A plan account will be established in the name of each Employee. All
Contributions to the MDSI Purchase Plan shall be held in trust by MDSI. MDSI
will not be required to segregate the Contributions under the Plan from its own
corporate funds or to pay interest thereon.

At the end of each MDSI fiscal quarter in which an Employee has subscribed for
Shares, the Employee will have the following options with respect to his
Contributions:

(a)   Authorize MDSI to convert the total Contribution to Shares at the
      previously established Subscription Price for that quarter, and issue such
      Shares to the Employee;

(b)   Authorize MDSI to continue to hold the total Contribution in trust for
      that Employee to be applied against future purchases of Shares at the
      Subscription Price to be established for the MDSI fiscal quarter in which
      the Employee elects to purchase the Shares, as instructed by the Employee
      from time to time.

In addition to the foregoing, each Employee's total Contribution may be refunded
to such Employee in any of the following circumstances:

(c)   on the death of an Employee, in which case such Employee's total
      Contribution may be refunded to such Employee's lawful heirs, executors or
      administrators at their option;

(d)   if the employment of an Employee is terminated for any reason other than
      death, in which case such Employee's total Contribution may be refunded to
      the Employee, at the Employee's option; or

(e)   in the event of any statutory merger, plan of arrangement, amalgamation,
      consolidation, sale of all or substantially all of the assets of MDSI, or
      sale, pursuant to an agreement with MDSI, of securities of MDSI pursuant
      to which MDSI is or becomes a wholly-owned subsidiary of another
      corporation after the effective date of such transaction, such Employee's
      total Contribution may be refunded to the Employee, at the Employee's
      option.

During an Employee's lifetime, an Employee's right to purchase Shares under the
MDSI Purchase Plan is exercisable only by the Employee, and an Employee's rights
under the MDSI Purchase Plan, including rights to accumulated payroll
deductions, may not be pledged, assigned, encumbered or otherwise transferred
for any reason other than by will or the laws of descent and distribution.

6. Issue of Shares

Thirty (30) days after the end of each of MDSI fiscal quarter, unless instructed
otherwise by the Employee in writing, MDSI will issue from its treasury and
deliver to each Employee, Shares equal in the value to the Contribution held in
trust on such date by MDSI for such Employee converted at the Subscription Price
for such quarter. If such conversion would otherwise result in the issue to an
Employee of a fraction of a share, MDSI will issue only such whole shares as are
issuable. MDSI shall hold any unused balance of the Contribution in trust for an
Employee until used in accordance with the MDSI Purchase Plan.

7. Hold Period

<PAGE>

All Shares issued to Employees under the MDSI Purchase Plan will be subject to a
180 day hold period.

8. RSP Option

An Employee may make an agreement with a trustee selected by him or her, on
terms complying with the Income Tax Act (Canada), to create a retirement savings
plan (RSP) which would receive and hold shares purchased under the MDSI Purchase
Plan. An Employee must specify both the maximum amount and the proportion of his
or her Contributions that may be paid into the RSP annually. Each Employee
should ascertain the advantages and disadvantages or an RSP for himself or
herself. Information is available from a number of sources including Revenue
Canada.

Part C- Employee Share Ownership Program

9. Method of Operation

Unless expressly stated otherwise, all provisions contained in the MDSI Purchase
Plan with respect to Contributions from Employees will apply to this Part C.

10. Provincial Tax Incentives

The Government of British Columbia will provide tax incentives under certain
conditions to Employees who invest in MDSI through the Employee Investment Act
and the Rules. The provincial tax credit is equal to 20% of the amount invested,
subject to a maximum of $2,000 per year and a lifetime exemption of $10,000.
Shares fully paid for in the first sixty (60) days of the year can have the tax
credit applied against income for that year or the previous year. The provincial
tax credits do not have any carry forward or carry back provisions.

11. Maximum Individual Contributions

The maximum value of Shares that an Employee may purchase and receive provincial
tax credits on is $10,000 annually and $50,000 lifetime. (i.e. 20% credit of
$10,000 = $ 2000 tax credit annually) The maximum aggregate value of Shares that
an Employee can purchase under the MDSI Purchase Plan and the ESOP is $10,000
per year. These Shares may also be put into an RSP for an additional federal tax
deduction.

12. Hold Period

All Shares issued to Employees and used for provincial tax credits under the
ESOP are subject to a three year hold period with an escrow agent, subject to
exceptions for the sale of the Shares in situations of hardship.

13. Purchase Method

Shares must be purchased by Employees either through payroll deduction or lump
sum to be eligible for tax credits under this Part C of the Plan.

14. Residency Requirement

An Employee must be a resident of the Province of British Columbia to be
eligible to participate in the ESOP.

Part D - General

15. Payment

At the discretion of the Committee and with sufficient advance notice, the full
purchase price for each of the Shares may be paid by all or none of the
Employees in cash or by certified cheque. An Employee shall have none of the
rights of a shareholder in respect of the Shares until the shares are issued to
such Employee.

16. Employment/Appointment

<PAGE>

Nothing contained in the Plan shall confer upon any Employee any right with
respect to employment or to continue in the service of MDSI, or interfere in any
way with the right of MDSI or its directors to terminate such Employee's
employment or service at any time. Participation in any part of the Plan is
voluntary.

<PAGE>

17. Termination of Employment or Service

If an Employee shall cease to be employed by or provide services to MDSI or any
of its subsidiaries for any reason or shall receive notice from MDSI of the
termination of his employment or involvement, the Employee shall be deemed to be
no longer eligible to participate under the Plan. All applicable hold periods on
the Shares will remain after the cessation of employment with MDSI or provision
of services to it. Upon termination of employment or involvement with MDSI, an
Employee who has fully completed his/her probationary period or any extension
thereof may only elect to deal with his/her unconverted Contribution in
accordance with section 5(a) or (d) hereof. Any Employee who does not fully
complete his/her probationary period or any extension thereof may only elect to
deal with his/her unconverted Contribution in accordance with section 5(d)
hereof.

18. Tax Matters

All Employees participating under the Plan are encouraged to seek advice from
their professional advisors with respect to the tax implications of the Plan.

19. Record Keeping

MDSI shall maintain a register in which shall be recorded:

(a)   the name and address of each Employee participating under the Plan;

(b)   the parts of the Plan in which he or she participates;

(c)   any Contributions made by such persons;

(d)   the number of Shares issued and the number of Shares outstanding.

20. Effective Date and Term

Subject to any longer period of time which may be authorized by regulatory
approval, the Plan shall be effective as of the Effective Date and shall
terminate on the earlier of:

(a)   the date which is ten years from the Effective Date; and

(b)   such other date as the Board may determine.

21. Plan Subject to Regulatory & Shareholder Approval

Any rights granted by MDSI prior to the date of the first annual general meeting
of the shareholders of MDSI duly convened following the introduction of the Plan
will be subject to the approval of the TSE, the ME, the Employee Investment Act
administrator and shareholders of MDSI. If such approvals are not obtained, each
and every right granted under the Plan shall be null and void and shall convey
no rights to the Employee and all funds held in trust will be returned.

22. Risk

The Plan offers no guarantee against loss due to market declines. Each Employee
participating in the Plan must accept the risks of market fluctuations as well
as the benefits of share ownership.

23. Expenses of Plan

MDSI will pay all administrative costs of the Plan.

<PAGE>

24. Maximum Number of Shares

Without further approval by the shareholders of MDSI, the maximum number of
Shares to be reserved for issuance by MDSI under the MDSI Purchase Plan and the
Employee Share Ownership Program will not exceed 100,000 shares in the
aggregate.

Notwithstanding any other provision of this Plan, in any MDSI fiscal year, the
maximum aggregate amount that an Employee may contribute under this Plan is
$10,000 per annum.

25. Securities Law Requirements

MDSI shall use all reasonable efforts but shall not be obligated to issue any
Shares pursuant to the Plan, if such issuance would, in the opinion of counsel
for MDSI, violate the Securities Act of British Columbia (or any other
applicable statute), as it may be in effect at that time. Each Share shall be
subject to the further requirement that if at any time the Committee determines
that the listing or qualification of the Share under any securities legislation
or other applicable law, or the consent or approval of any governmental or other
regulatory body (including any applicable stock exchange), is necessary as a
condition of, or in connection with, the issue of the Share hereunder, such
Share shall not be issued unless such listing, qualification, consent or
approval has been effected or obtained free of any conditions not acceptable to
the Committee.

26. Amendment of the Plan

(a)   The Board may subject to regulatory approval, amend the Plan if such
      amendment is in compliance with the rules of the TSE, the ME and the ESOP.
      The Committee may correct any defect or supply any omission or reconcile
      any inconsistency in the Plan in the manner and to the extent it deems
      desirable to carry the Plan into effect without action on the part of the
      shareholders of MDSI; provided, however, that except as provided for
      adjustment in this Section 26, unless the shareholders of MDSI shall have
      first approved thereof the total number of Shares to be issued shall not
      be increased beyond those contemplated in the Plan.

(b)   The Board shall have the power, in the event of:

      (i)   any disposition of substantially all of the assets of MDSI,
            dissolution or any merger, amalgamation or consolidation of MDSI,
            with or into any other corporation, or the merger, amalgamation or
            consolidation of any other corporation with or into MDSI; or

      (ii)  any acquisition pursuant to a public tender offer of a majority of
            the then issued and outstanding common shares without par value of
            MDSI;

      to, subject to compliance with the rules of the Employee Investment Act,
      the TSE and the ME, amend all outstanding subscription agreements with its
      Employees to permit the issuance of all such Shares subscribed and paid
      for in full prior to the effectiveness of any such transaction, and to
      terminate such subscription agreements as of such effectiveness in the
      case of transactions referred to in subsection (i) above, and as of the
      effectiveness of such tender offer or such later date as the Board may
      determine in the case of any transaction described in subsection (ii)
      above. If the Board exercises such power, all Employee subscription
      agreements then outstanding and subject to such requirements shall be
      deemed to have been amended to permit the issuance of the exercise thereof
      in whole or in part by the Employee at any time or from time to time as
      determined by the Board prior to the effectiveness of such transaction,
      and such subscription agreements shall also be deemed to have terminated
      as provided above.

      all liens, pledges, charges, encumbrances, claims, security interests and
      liabilities other than those disclosed to DDS hereunder), in exchange for
      the issuance from treasury by DDS to MDSI of 11% of the issued and

      liabilities other than those disclosed to MDSI) , and an unsecured
      promissory note (the "Promissory Note") granted by DDS in favour of MDSI

      MDSI-UK), to DDS in a tax-effective manner. MDSI also agrees that all
      MDSI-TBU contracts held by MDSI Software B.V. shall be transferred to
      MDSI-UK.

      However, prior to the Closing:

      (a)   Assets, Liabilities and Employees Unrelated to MDSI-TBU: All assets
            and liabilities of MDSI-UK which are unrelated to the MDSI-TBU (as
            set out on Schedule "A1") shall, at MDSI's direction and with
            disclosure to DDS, be transferred to and assumed by MDSI or other
            MDSI affiliates with such capital assets and liabilities to be
            transferred at net book value and all inventory to be transferred at
            the lower of cost and net realizable value, and all employees of
            MDSI-UK who are unrelated to MDSI-TBU (as listed on Schedule "A1",
            including Roy Manktelow, Barry Edgar, Paul Wilkin, Jouni Rouppa and

            assumed by MDSI or other MDSI affiliates on Closing but effective as
            of the Effective Date. In connection with this transfer and
            assumption, DDS agrees that for a period of up to 90 days following
            Closing, DDS shall provide to MDSI, at a cost of (pound)1,500 per
            month, the office space currently used and occupied by Barry Edgar,
            Roy Manktelow and Paul Wilkin for the continued use of and
            occupation by them, as well as providing telephone answering
            services, access to coffee, kitchen and

            washroom facilities and access to a boardroom based on availability.
            DDS will charge telephone expenses attributable to Messrs. Edgar,
            Manktelow and Wilkin during this period to MDSI based on the records
            generated by MDSI-UK's telephone billing system. On or before the
            expiry of this 90-day period, Messrs. Edgar and Wilkin will vacate
            the premises.

      (b)   MDSI-TBU Restructuring: MDSI shall restructure the MDSI-TBU (with
            full disclosure to DDS) such that on Closing (but then effective as
            of the Effective Date) MDSI-UK and MDSI-Singapore shall have a net
            book value of $1,000,000 calculated in accordance with Canadian GAAP
            using as a currency exchange rate the noon buying rate as recorded
            by the United States Federal Reserve Board on the Effective Date,
            with the Consolidated Proforma Balance Sheet of MDSI-TBU as at the
            Effective Date (consolidating the balance sheets of MDSI-UK and
            MDSI-Singapore only), a draft of which is attached as Schedule "J"
            hereto (the "MDSI-TBU Proforma"), which shall be superseded by a
            final version delivered on the Closing Date and upon which such
            calculation is based to include the following items as liabilities:

            Any receivables at Closing not required by MDSI to make the
            $1,000,000 net book value (the "Excess Receivables") will be
            collected by DDS and remitted to MDSI (with the oldest receivable
            being collected in priority to the newer receivables).

      Within 30 days after the date of delivery by MDSI to DDS of the MDSI
      Closing Financial Statements in accordance with section 5.5 hereof, MDSI
      and DDS shall meet in order to make and settle post-Closing adjustments
      with respect to the MDSI-TBU Proforma, including, without limitation,
      matters relating to unbilled receivables, customer deposits and deferred

      post-Closing adjustments owed by either MDSI or DDS to the other, as the
      case may be, shall be delivered at the meeting by the applicable party to
      the other party. If the post-Closing adjustments are not agreed on and so
      paid for within such 30 day period, the matter shall be resolved by an
      independent arbitrator in accordance with and subject to the arbitration
      provisions set out in section 9.6 hereof, with the net amount of the
      adjustments determined owing by the arbitrator to bear interest at the
      rate of 10% per annum, calculated from the Closing Date to the date
      payment in full is made. The amount so determined, plus interest, together
      with any costs awarded by the arbitrator, shall be final and binding on
      the parties and shall be paid by the applicable party to the other
      forthwith following delivery of the arbitrator's decision. No amount so
      payable shall be subject to any of the limitations set out at section 9.2
      hereof .

2.2   Anti-Dilution Protection In Connection With Stock Option Exercises. With
      respect to the possible post-Closing dilution of MDSI's shareholding in
      DDS as a result of the exercise by others of existing or future options
      ("Third Party Options") to purchase DDS Shares, MDSI shall have the right,
      while DDS is a private company, and within 30 days after each such
      exercise of Third Party Options, to purchase from treasury at a price of
      $6.50 per share,

<PAGE>
                                      -5-


      further DDS Shares sufficient to maintain MDSI's then current
      proportionate shareholding in DDS. This purchase price of $6.50 per
      further DDS Share shall survive for a period of 2 years following the date
      of Closing and thereafter shall be such price per further DDS Share as is
      equal to the greater of: (a) $6.50; and (b) the exercise price of such
      Third Party Options. All waivers of pre-emptive rights required from other
      DDS shareholders to enable MDSI to exercise this right shall be obtained
      by DDS.

2.3   Permitted Dilution. With respect to the possible post-Closing dilution of
      MDSI's shareholding in DDS by the future acquisition from time to time by
      DDS of shares, assets or other property or services from an arm's length
      party or parties through the issuance of DDS Shares (at fair market value,
      determined by the directors of DDS acting reasonably), MDSI agrees to
      waive its preemptive rights to participate with respect to the allotment
      and issuance of any such DDS Shares.

2.4   Transfer of Ownership and Assumption of Liabilities. Except as
      specifically provided elsewhere in this Agreement: up to the time of
      Closing, MDSI shall own, have the full benefit of and be responsible for
      all obligations and liabilities attaching to the MDSI-TBU Assets, and from
      and after the time of Closing, DDS shall own, have the full benefit of and
      be responsible for all obligations and liabilities attaching to the
      MDSI-TBU Assets.

2.5   Investigation. Prior to Closing, DDS, MDSI and their respective
      representatives shall be permitted to make such investigations of the
      MDSI-TBU and the MDSI-TBU Assets (in the case of DDS) and of DDS (in the
      case of MDSI) and of their respective financial and legal condition as
      each of the parties deems necessary or desirable and without limiting the
      generality of the foregoing, shall, during normal business hours, be
      permitted full and complete access to the premises, books, minute books,
      contracts, leases, documents, data and other records of the MDSI-TBU (in
      the case of DDS) and of DDS (in the case of MDSI) (and each of the parties
      shall provide photocopies to the other of all such written information and
      documents as may be reasonably required by or on behalf of the other). Any
      such investigation shall not, however, affect or mitigate the
      representations, warranties and covenants of the parties (or those
      relating to any of their applicable affiliates) hereunder (or under any
      agreement or instrument delivered pursuant hereto or in connection
      herewith), which shall continue in full force and effect as provided
      hereunder.

2.6   Interim Period Management. During the period from the Effective Date to
      the Closing (the "Interim Period"), DDS shall manage the MDSI-TBU, subject
      to consultation with and approval by Chris Duncombe of MDSI on major
      decisions. Notwithstanding the foregoing, if the Transaction is not
      completed as contemplated herein, all risk associated with the Interim
      Period shall be borne by MDSI. If the Transaction is completed as
      contemplated herein, all risk associated with the Interim Period shall be
      borne by DDS.

            information and belief, there is no patent or application therefor
            or investigation by any Person that would adversely affect the
            MDSI-TBU or any product, apparatus, method, process or design of

      (cc)  Leases: Schedule "D" contains an accurate and complete list of

            respect of which consents of landlords and/or others are required to
            the Transaction. None of the Leases contains any provision which as
            a result of the Transaction will: (i) increase the lessee's cost of
            operating the Leasehold Property; (ii) result in the lessee being
            deprived of any right under such Lease; nor (iii) interfere with the
            lessee's ability to conduct or continue to conduct its business on
            such Leasehold Property in accordance with the terms of the Lease.
            The Leasehold Properties are all in a good state of repair and
            comply with all statutes, regulations, codes and by-laws. All of the
            Leasehold

            Properties are properly zoned to permit the current use of such
            Leasehold Properties. Neither MDSI-UK nor MDSI-Singapore has
            received, with respect to any Leasehold Property, any notice from
            any municipal or other governmental authority relating to work
            orders, or other compliance orders, or relating to any local

                  assigned to them herein

            (i)   "MDSI-TBU Software" shall include all "Software Products"
                  included in the MDSI-TBU IP Assets, including microcode,
                  firmware, application programs, files and database developed
                  or acquired by MDSI to form part of the MDSI-TBU Software.

                  evenly divisible by 100. For example, the year 1996 is a Leap
                  Year since it is evenly divisible by 4 and not evenly
                  divisible by 100. The year 2000 is a Leap Year since it is
                  evenly divisible by 400.

                  include, but shall not be limited to, the functions of
                  comparing, sorting, or otherwise manipulating, performing

            (iv)  With respect to the MDSI-TBU Software, "Year 2000 Compliant"
                  shall mean that such MDSI-TBU Software correctly processes
                  valid, accurate and correct date data (including, but not
                  limited to, calculating, comparing, and sequencing) from,
                  into, and between the twentieth and twenty-first centuries,
                  including Leap Year calculations, without impairing the
                  performance, output or accuracy of the system or products
                  based on the MDSI-TBU Software.

      (b)   Y2K Representation: MDSI represents and warrants that the MDSI-TBU
            Software when used with the hardware, operating system software and
            database software chosen by MDSI to meet the MDSI obligation set out
            in the Material Contracts is Year 2000 Compliant. Notwithstanding
            any other provision of this Agreement, MDSI's sole obligation and

                  the Other Agreements and would not be reasonably likely to
                  have a material adverse effect on DDS; and

            (v)   those consents set out in section II.6 (a) of the Document
                  List;

      (aa)  Insurance: DDS and DDS-US have their assets insured under policies
            of insurance issued by responsible insurers against loss or damage
            with coverage of a type and in an amount consistent with the types
            and amounts of insurance maintained by corporations of a size and
            carrying on businesses of the type carried on by DDS and DDS-US. To
            the best of its knowledge, information and belief, all such policies
            of insurance are set forth in Schedule "C" and are in full force and
            effect and there is no default, whether as to payment of premium or
            otherwise, under the terms of any such policies;

      (bb)  No Bankruptcy, etc.: There has not been filed any petition or
            application, or any proceedings commenced which have not been
            discharged, by or against DDS with respect to any of the DDS Shares
            or any of its assets under any law, domestic or foreign, relating to
            bankruptcy, receivership or winding up, reorganization, compromise
            arrangements, insolvency, readjustment of debt or creditors' rights,
            and no assignment or proposal for the benefit of creditors has been
            made by DDS;

      (cc)  Intellectual Property: The DDS IP Assets are valid and subsisting.
            There are no unresolved conflicts with, threatened or pending claims
            of, or potential, written threats or pending claims by DDS against,
            any other Person, whether in litigation or otherwise, involving the
            DDS IP Assets and, except as set out in Schedule "G", there are no
            liens, pledges, charges, encumbrances, claims, security interests or
            rights of any other Person, including moral rights, with respect to
            the DDS IP Assets or which would prevent DDS from fulfilling its
            obligations under this Agreement and the Other Agreements. No
            activity of any employee of DDS as or while an employee thereof has
            caused a violation of any trade secret of DDS. To the best of DDS's
            knowledge, information and belief, there is no patent or application
            therefor or investigation by any Person that would adversely affect
            DDS or any product, apparatus, method, process or design of DDS. To
            the best of DDS's knowledge, information and belief, there is no
            government restriction or any limitation, domestic or foreign, on
            the manner in which any of the DDS IP Assets may be used which
            materially negatively affects DDS's business;

      (dd)  Leases and Real Property Interests: Schedule "C" contains an
            accurate and complete list of leases (the "Leases") of real or
            personal property (the "Leasehold Property") to which DDS or DDS-US
            is a party and a list of the real property held by DDS or DDS-US
            (the "Freehold Property"). DDS has made available to MDSI true and
            complete copies of all the Leases and the summary title documents
            relating to the Freehold Property. None of the Leases has been or is
            being further modified or amended or assigned and all rents and
            additional rents required to be paid and all obligations required to
            be performed by the lessee thereunder have paid and performed.
            Except as disclosed in Schedule "E", the

<PAGE>
                                      -24-


            Leases and the Freehold Property have not been encumbered and all
            the Leases are good, valid and subsisting and are in full force and
            effect. Schedule "C" identifies the Leases in respect of which
            consents of landlords and/or others are required to the Transaction,
            and Schedule "E" identifies all encumbrances on the Freehold
            Property in respect of which consents of encumbrancers are required
            to the Transaction. None of the Leases contains any provision which
            as a result of the Transaction will: (i) increase the lessee's cost
            of operating the Leasehold Property; (ii) result in the lessee being
            deprived of any right under such Lease; nor (iii) interfere with the
            lessee's ability to conduct or continue to conduct its business on
            such Leasehold Property in accordance with the terms of the Lease.
            The Leasehold Properties and the Freehold Property are all in a good
            state of repair and comply with all statutes, regulations, codes and
            by-laws. All of the Leasehold Properties and the Freehold Property
            are properly zoned to permit the current use of such Leasehold
            Properties and the Freehold Property. Neither DDS nor DDS-US has
            received, with respect to any Leasehold Property or the Freehold
            Property, any notice from any municipal or other governmental
            authority relating to work orders, or other compliance orders, or
            relating to any local improvement charges, levies or assessments or
            relating to expropriation; and

      (ee)  Y2K Representation: DDS represents and warrants that the latest
            version of each of the products of comprising the DDS Software is
            year 2000 compliant.

5. COVENANTS OF MDSI

MDSI hereby covenants and agrees with DDS as follows:

5.1.1 Copenhagen Taxi Costs and Revenue. MDSI will manage the Copenhagen Taxi
      contract of MDSI-UK to the point in time (the "Site Acceptance Time") that
      MDSI has successfully passed a site acceptance test with Copenhagen Taxi,
      with no material variation from the acceptance terms contained within the
      terms of the Copenhagen contract unless agreed to in writing with the
      Customer and agreed to in writing by DDS, and throughout this period MDSI
      shall provide all disclosure to DDS as reasonably requested by DDS. DDS
      shall be entitled, at its own expense, to have any of its employees or
      representatives attend the site acceptance test or any other significant
      meetings or tests, provided that such attendance will be strictly in the
      capacity of an observer, and such employees or representatives shall not
      participate in or influence any discussions with the customer. All
      revenues, benefits, costs, penalties, discounts and other liabilities
      associated with the Copenhagen Taxi project accrued and owing up to and
      including the Site Acceptance Time will be for MDSI's account. Effective
      at the Site Acceptance Time, MDSI will transfer on an orderly basis and
      DDS will assume management of the Copenhagen Taxi project and all the
      benefits and the obligations thereunder, however, all liability for
      penalties under the supply contract shall be borne solely by MDSI and all
      such discounts shall be paid for solely by MDSI in cash to the customer or
      to DDS. Accordingly, all of the benefits and obligations under the support
      and maintenance contract will be solely for the account of DDS. In
      furtherance of this covenant, the supply contract will be assigned to MDSI
      at Closing and then assigned to DDS effective at the Site Acceptance Time.
      In addition, MDSI agrees not to make any amendments to the existing
      maintenance agreement with respect to incurring any additional discounts
      without DDS's consent. From the Site Acceptance Time forward, all
      revenues, benefits, costs and other liabilities (except for penalties
      accrued and owing prior to the Site Acceptance Time) associated with the
      Copenhagen Taxi project will be for DDS's account. MDSI acknowledges and
      agrees that, from and after Closing, all MDSI-TBU IP Assets associated
      with or developed in connection with the Copenhagen Taxi project (except
      for the Oracle licenses registered in the name of MDSI) shall be the sole
      property of DDS directly or indirectly (through MDSI-UK), that MDSI shall
      have no right, title and interest therein and that MDSI shall not use such
      MDSI-TBU IP Assets except for the purpose of performing its management
      obligations set out above. MDSI shall not duplicate any of such MDSI-TBU
      IP Assets and it shall not disclose or permit access to any of such
      MDSI-TBU IP Assets to any Person other than disclosure on a "need to know"
      basis to its direct employees or contractors working on the project (a
      list of whom shall be provided to DDS on Closing and updated from time to
      time) and who have signed appropriate confidentiality agreements and
      agreements relinquishing and assigning any and all rights in and to such
      MDSI-TBU IP Assets. MDSI shall indemnify and hold harmless DDS for costs,
      losses or damages it may incur arising from a breach by it of such
      confidentiality and non-use covenants. MDSI

<PAGE>
                                      -25-


      also agrees that on a timely basis following the Site Acceptance Time, it
      shall deliver to DDS all MDSI-TBU IP Assets, data and materials (and all
      copies thereof) associated with the project, and that within 30 days
      following the Site Acceptance Time it shall separately transfer to DDS, at
      DDS' discretion, all assets used by MDSI in connection with the Copenhagen
      project for a price equal to their aggregate net book value as of the Site
      Acceptance Time. At such time, MDSI and DDS shall also adjust and settle
      all other amounts owing or claims between them regarding the Copenhagen
      Taxi project, and any dispute between them regarding such settlement shall
      be resolved by arbitration on the same terms and conditions as apply for
      resolving post-Closing adjustments set out in section 2.1 above including
      that such adjustment shall not be subject to the limitations set out in
      section 9.2 hereof.

5.1.2 Copenhagen Warranty Reserve. The Copenhagen warranty reserve provided in
      section 2.1(b) is provided on the basis that DDS will provide warranty
      services for a 14 month warranty period under the service agreement to
      Copenhagen Taxi, and DDS shall indemnify MDSI for any liability incurred
      under the MDSI guarantee granted to Copenhagen Taxi for any breaches under
      the service agreement with Copenhagen Taxi.

5.2   Underwriters' Terms and Restrictions. MDSI will agree to the commercially
      reasonable terms of the underwriting agreement entered into by DDS when
      DDS initially becomes a publicly traded entity, including any hold period
      on the disposition of DDS Shares required by the underwriters, provided
      that such hold period is no longer than 6 months.

5.3   Marketing to Airborne Freight Corporation. MDSI shall provide reasonable
      support to DDS in DDS's efforts to market DDS's products and services to
      Airborne Freight Corporation. If, with respect to a future DDS project
      involving Airborne Freight Corporation, resources are required from MDSI
      with respect to installation, testing or support, MDSI will provide such
      services on a "time and materials" basis to DDS at MDSI's standard market
      rates at that time. Such support shall not include any access to the
      Advantex Courier software source code used on the Airborne Freight
      Corporation project by DDS. Any licenses to the Advantex Courier software
      executable code to be sublicensed to Airborne Freight Corporation will be
      negotiated between MDSI and DDS.

5.4   Accounts Receivable. If any accounts receivable of MDSI-TBU in the MDSI
      TBU Proforma delivered at Closing (other than those Excess Receivables
      described in section 2.1(b))are not recovered by DDS within 90 days after
      Closing (provided that reasonable efforts to recover such receivables have
      been made by DDS), MDSI shall pay DDS the amounts of such accounts
      receivable, provided that DDS assigns the right to collect such accounts
      receivable to MDSI.

5.4.1 Unbilled Receivables. If any unbilled receivable of MDSI-TBU in the
      MDSI-TBU Proforma delivered at Closing are not recovered by DDS within 90
      days after Closing (provided that reasonable efforts have been made by DDS
      to collect if billable) MDSI shall pay DDS the amounts of such
      receivables, provided that DDS assigns the right to collect such
      receivables to MDSI. DDS will use all reasonable commercial efforts to
      complete all bug fixes with respect to the Radio Taxi London installation
      and DDS will support MDSI with respect to MDSI's collection of such
      receivables.

5.5   Financial Statements. On or prior to Closing, MDSI shall provide DDS with
      copies of the MDSI-UK Financial Statements and of the MDSI-Singapore
      Financial Statements and, as soon as practicable after Closing, MDSI shall
      provide DDS with copies of the MDSI Closing Financial Statements. In
      connection with the review engagement process regarding the MDSI Closing
      Financial Statements, DDS agrees to provide all necessary assistance to
      the auditor or auditors carrying out such reviews, and MDSI shall be
      responsible for all costs in connection with obtaining these review
      engagement reports, such that these costs will not form part of the
      post-Closing adjustments. The MDSI Closing Financial Statements shall be
      prepared in accordance with generally accepted accounting principles
      applied on a basis consistent with that of previous years and shall
      present fairly in all material respects the financial position of MDSI-UK
      and MDSI-Singapore as at Closing and the results of their respective
      operations and the changes in their respective financial positions for the
      5 month period then ended. Also in connection with the review engagement
      process, DDS agrees to give MDSI full and free access to, and the right to
      supervise and direct,

<PAGE>
                                      -26-


      the process of preparing the MDSI Closing Financial Statements and review
      engagement reports, and DDS will deliver at Closing a Direction of DDS
      addressed to MDSI-UK and MDSI-Singapore to that effect.

5.6   RTL Voice Fall Back. MDSI shall retain DDS at the rate of $600 per man day
      plus expenses at cost, to assist MDSI in the completion of the RTL voice
      fall back functionality. If after Closing, RTL decides to submit to
      arbitration the matter of whether MDSI has met the voice fallback
      requirements as set out in MDSI-UK's contract with RTL and such
      arbitration results in a finding that MDSI has not met such requirements,
      at the direction of MDSI, DDS will make the human resources available so
      that DDS can modify the code or supply any software or hardware required
      to satisfy the arbitrator's decision. MDSI shall have full control of the
      applications made in respect of such arbitration and DDS will cooperate
      fully in support of MDSI's application to the arbitrator and support
      MDSI's position. In such case MDSI shall be liable to DDS for the costs of
      such modifications to software and hardware (including any related
      expenses) with such costs of any DDS services to be at the same man day
      rate and expenses noted above.

5.7   DDS Shareholders' Agreement. MDSI shall execute the DDS Shareholders'
      Agreement at Closing.

5.8   Release of Certain Encumbrances. MDSI shall obtain a release or consent to
      transfer in respect of the sale of the MDSI-TBU Assets which are currently
      encumbered under any security instrument or agreement, including without
      limitation, under the General Security Agreement between MDSI and the Bank
      of Montreal.

5.9   Documents and Data. On the Closing Date, MDSI shall deliver or cause to be
      delivered to DDS all minute books, corporate seals and corporate records
      relating to MDSI-UK and MDSI-Singapore, together with all documents (or
      copies thereof) and other data (technical, financial or otherwise) in the
      possession of MDSI and its affiliates, which relate to the MDSI-TBU and/or
      the MDSI-TBU Assets or which will be necessary for the conduct of the
      MDSI-TBU after the Closing Date including, without limitation, such
      operating manuals, books of account and financial records as DDS may
      request.

5.10  Grants. If DDS or MDSI UK is required to repay all or any part of the
      150,000 British pound grant from the British Government to MDSI UK , MDSI
      shall repay DDS, and the threshold limitations set out in section 9.2
      shall not apply to any claim by DDS based on this covenant. DDS shall not
      initiate any communications with the British Government with respect to
      this grant and will not answer any questions with respect to this grant
      (without due consultation with MDSI), except as required by law. This
      section 5.10 and the covenants contained in this section 5.10 shall
      survive the Closing and continue in full force and effect indefinitely for
      the benefit of DDS.

6. COVENANTS OF DDS

DDS hereby covenants and agrees with MDSI as follows:

6.1   DDS Options. In addition to the anti-dilution protection set out at
      section 2.2, DDS will not, pursuant to any share compensation arrangement,
      reserve for issuance DDS Shares, or grant share options to directors,
      officers, employees, consultants or any other service providers
      exerciseable for an amount of DDS Shares representing in the aggregate
      greater than 20% of the issued and outstanding shares of DDS at the time
      of grant, and DDS will not grant to any one director, officer, employee,
      consultant or other service provider of DDS share options pursuant to
      share compensation arrangements exerciseable for an amount of DDS Shares
      representing greater than 5% of the issued and outstanding shares of DDS
      at the time of grant. For the purposes of this section 6.1, "share
      compensation arrangement" and "service provider" shall have the meanings
      ascribed to such terms in section 627 of The Toronto Stock Exchange
      Company Manual.

<PAGE>
                                      -27-


6.2   DDS To Be Taken Public. DDS shall use all commercially reasonable efforts
      and shall become a publicly traded entity by the later of the following
      three deadlines (the "First Penalty Date"): (a) two years from the Closing
      Date (the "First Deadline"); (b) six months from the date of the First
      Deadline if, at the time of the First Deadline, DDS has entered into a
      bonafide enforceable underwriting or agency agreement with a registered
      dealer to take DDS public or DDS has entered into any other binding
      agreement (e.g., amalgamation) the completion of which will result in DDS
      becoming a publicly traded entity; or (c) one year from the First
      Deadline, if either of the following two circumstances exists on the First
      Deadline: (i) "market out" conditions exist as evidenced by the figure on
      the IPO index to be agreed to by the parties prior to Closing, , or (ii)
      DDS has not been offered terms by an underwriter or registered dealer to
      be taken public on a "best efforts" agency basis or better for a value
      that represents 1.5 times the annual revenue of DDS or 15 times the net
      earnings of DDS (the foregoing circumstances being the "Market Out
      Conditions"), both such circumstances being measured on the 4 financial
      quarters prior to the First Deadline Date proposed to be included in the
      offering memorandum, prospectus or other securities document regarding the
      proposed offering.. If DDS is not a publicly traded entity by the First
      Penalty Date, then DDS shall issue 170,601DDS Shares from treasury to MDSI
      forthwith (which amount equals 20% of the Purchased DDS Shares on the
      Effective Date). If DDS is not a publicly traded entity by the first
      anniversary date after the First Deadline and by each subsequent
      anniversary date thereafter (each such date being a "Subsequent
      Deadline"), then DDS shall issue 85,301 DDS Shares from treasury forthwith
      to MDSI (which amount equals 10% of the Purchased DDS Shares on the
      Effective Date). Notwithstanding the foregoing, if on the First Penalty
      Date or any Subsequent Deadline, either of the Market Out Conditions still
      exists and DDS is not a publicly traded entity, DDS shall not be required
      to issue the DDS Shares which are due on the First Penalty Date or that
      Subsequent Deadline (and the First Penalty Date and/or the Subsequent
      Deadline shall be moved one year into the future). In addition to the
      foregoing, and notwithstanding Part 5 of the DDS Shareholders' Agreement,
      at any time after 6 months prior to the First Deadline, DDS shall have the
      right to purchase or arrange for another party or parties to purchase
      MDSI's interest in DDS for an amount equal to the number of DDS Shares
      held by MDSI on the date DDS gives written notice to MDSI of its intention
      to exercise such purchase right, multiplied by the DDS Valuation Price on
      that date (provided that if DDS goes public within 9 months of such
      purchase, the purchase price will be adjusted to reflect the net proceeds
      per share realized on the public offering, as further adjusted, if
      necessary for example, for stock splits and share consolidations and
      similar matters).

6.3   Permitted Encumbrance of MDSI's Shareholding. MDSI shall have the right to
      encumber its shareholding in DDS under MDSI's security agreements with its
      bankers, provided that the terms of such security agreements do not
      prohibit the transfer of such shareholding by MDSI pursuant to the DDS
      Shareholders' Agreement or hereunder and the same is acknowledged in
      writing by such bankers. DDS hereby consents to any such encumbrance for
      the purpose of section 2.2 of the DDS Shareholders' Agreement.

6.4   Provision of Financial Information. DDS shall provide quarterly unaudited
      and annual audited financial statements to MDSI as soon as possible upon
      such financial statements being produced, and MDSI agrees to keep any such
      financial statements confidential.

6.5   Payment of Taxes. DDS will be liable for and will pay all sales and
      transfer taxes, federal taxes and all other taxes, duties or other like
      charges properly payable upon and in connection with the conveyance and
      transfer of the MDSI-TBU Assets by MDSI to DDS including but not limited
      to GST, sales tax under the Social Services Tax Act (British Columbia) and
      Stamp Duties in connection with the transfers of the MDSI-TBU IP Assets,
      the MDSI-UK and, if any, the MDSI-Singapore Shares, and DDS will indemnify
      and hold harmless MDSI for any such outstanding amounts.

6.6   Financial Statements. On or prior to Closing, DDS shall provide MDSI with
      copies of the DDS Financial Statements.

6.7   Airborne Freight Corporation Settlement. DDS acknowledges that MDSI is
      currently involved in a contractual dispute with Airborne Freight
      Corporation. DDS agrees that MDSI shall have the right to pursue Airborne
      Freight Corporation with respect to payment under this contract, provided
      that MDSI does not commence any litigation proceedings. DDS further agrees
      that MDSI shall be entitled to and shall retain 100% of any and all

<PAGE>
                                      -28-


      settlement proceeds obtained by MDSI from Airborne Freight Corporation in
      connection with this matter, provided that such settlement shall occur
      either prior to Closing or up to 90 days after the Closing Date (except
      that any payments to be made by Airborne Freight Corporation to MDSI
      relating to such settlement may be made over time, beyond such time
      period).

6.8   Retention of MDSI-UK Employees Required to Complete Copenhagen Taxi
      Contract. DDS shall use commercially reasonable efforts to retain , David
      Weeden, Bernie Goosman, and Steve Burt (the "Retained Employees"), whose
      services MDSI has confirmed it requires to fulfill its obligations
      regarding the Copenhagen Taxi project under section 5.1 hereof, as
      employees of MDSI-UK after Closing, and DDS shall not terminate or
      constructively dismiss the Retained Employees, or take any steps in
      furtherance of same, until after the Site Acceptance Time. MDSI shall pay
      DDS for the services of the Retained Employees at the rates set out in
      section 7.2 below.

6.9   Employment Contract and Employee Information. Prior to Closing, DDS shall
      provide to Kenneth R. Miller, CEO of MDSI, on a strictly confidential
      basis for his review only the following information in written form: a
      list of the range of salaries (including all bonuses, incentives, benefits
      and other compensation) of all DDS employees and a copy of the standard
      form of employment agreement used by DDS for its employees.

6.10  Discontinuance of Use of Names, Trademarks, Etc. Within 90 days of
      Closing, DDS shall discontinue, and cease and desist from, the use of all
      names, trademarks, slogans and logos currently used by MDSI and its
      affiliates in connection with the MDSI-TBU. Provided DDS takes or causes
      to be taken all commercially reasonable steps required to effect and
      complete the change of name of MDSI-UK to Digital Despatch (UK) Ltd. and
      of MDSI-Singapore to Digital Despatch Pte. Ltd., or any such similar names
      on Closing (and DDS will promptly provide MDSI with evidence of same) no
      later than 30 days from the date of such name changes, DDS shall ensure
      that all new proposals and letterhead and any legal agreements are entered
      into under the applicable DDS legal name.

6.11  Auselda or other commission: If MDSI brings a substantial customer to DDS
      or its affiliates (the total consideration being over UK Pounds 1,000,000,
      such as for example Rome Taxi or Milan Taxi through Auselda) which results
      in a signed contract, within 12 months of the Closing Date DDS will pay
      MDSI a commission of 3% of the gross margin on the total consideration
      under such customer contracts. MDSI (or as MDSI may direct) will be paid
      such commission when DDS receives its milestone payments from such
      customers so that MDSI receives its commission on a pro-rata basis with
      each milestone payment.

7. MUTUAL COVENANTS AND OF DDS AND MDSI

DDS and MDSI each mutually covenant and agree with one another as follows:

7.1   No Solicitation. Subject to section 7.2 below, both MDSI and DDS will not
      solicit each other's existing employees for a period of 3 years from the
      date of Closing, except that DDS shall be entitled to solicit any or all
      MDSI employees who are employed by MDSI-TBU at Closing, as set out in the
      list at Schedule "M".

7.2   Provision of Employee Services. The parties acknowledge and agree that
      during the transition period immediately following the Effective Date, DDS
      will require the services of certain MDSI employees and, in order to
      complete the Copenhagen Taxi project, MDSI will require the services of
      certain employees of DDS, and each of the parties agrees to make such
      services available to the other. In connection with these arrangements, ,
      the party receiving such services will pay the other party an amount per
      employee equal to that employee's salary or hourly rate multiplied by 1.4.
      For greater certainty, each party shall hire and be responsible for their
      own contractors from and after the Effective Date (except for S. Bond who
      shall be DDS's responsibility).

7.3   Confidential Information. Any Confidential Information provided by either
      party to the other during the course of the due diligence investigation
      carried out in connection with the Transaction shall be kept confidential
      by the receiving party, its employees and professional advisors and will
      not be disclosed to any other Person for a period expiring on May 31,
      2004. Any obligations hereunder relating to the non-disclosure of the
      source code and trade secrets of a party shall remain in force and effect
      indefinitely. For the purposes of this section 7.3, "Confidential

<PAGE>
                                      -29-


      Information" shall mean all information regarding the business and affairs
      of DDS or MDSI, as the case may be, furnished by or on behalf of the other
      party or its affiliates, directors, officers, employees, agents,
      professional advisors or controlling persons in connection with the due
      diligence investigation carried out by each of DDS and MDSI in connection
      with the Transaction. Any information provided by either party to the
      other will not be deemed Confidential Information if it is generally
      available to the public, it is or becomes known to the receiving party
      independently of the party providing the information, or it is obtained
      from a third party without restriction and without breach of this
      Agreement.

7.4   Consents and Notices. After the Closing of the Transaction:

      (a)   each of DDS and MDSI shall use all reasonable efforts, and the
            parties shall cooperate with each other to obtain, all consents,
            waivers, approvals, and authorizations, which may be necessary to
            effect the Transaction; and

      (b)   each of DDS and MDSI will promptly execute and file, or join in the
            execution and filing of, any application or other document that may
            be necessary in order to obtain the authorization, approval or
            consent of any governmental entity which may be reasonably required,
            or which the other party may reasonably request in connection with
            the consummation of the Transaction. Each of DDS and MDSI will use
            reasonable efforts to obtain promptly all such authorizations,
            approvals and consents.

7.5   Press Releases. Before issuing any press release or otherwise making any
      public statements with respect to the Transaction, DDS and MDSI shall
      consult with each other and shall undertake reasonable efforts to agree
      upon the terms of such press release, and shall not issue any such press
      release or make any such public statement prior to such consultation,
      except as may be required by applicable law or by obligations pursuant to
      any listing agreement with any stock exchange or national securities
      exchange.

7.6   Y2K Covenant. Notwithstanding anything in this Agreement to the contrary,
      MDSI's sole liability with respect to Year 2000 Compliance and Y2K defects
      is set out in this section 7.6. For the purposes of this section 7.6,
      "Material Contracts" shall mean the customer agreements (in the form in
      which such agreements exist at Closing) included with the MDSI-TBU
      Material Contracts acquired by DDS under this Agreement.

7.6.1 MDSI shall continue and complete its Y2K testing on the MDSI-TBU Software
      Products until and on the Closing Date (except for the Copenhagen project
      which will continue until the Site Acceptance Time). DDS shall perform all
      reasonable further Y2K testing on the MDSI-TBU Software Products for the
      remainder of the year 1999. If DDS discovers and demonstrates that there
      is a substantial Y2K defect (meaning a single defect or batch of defects
      requiring an aggregate of more than 15 man days to correct in the MDSI-TBU
      Software Products supplied under one or more Material Contracts, primarily
      attributable to MDSI and not materially attributable to any other party
      including DDS; a "Substantial Y2K Defect"), and MDSI's sole
      responsibility, except as described in section 7.6.3, shall be to pay the
      costs for DDS to remedy such Substantial Y2K Defect(s) at the rate
      calculated in accordance with section 7.2. If DDS's estimates for the
      costs to remedy are unreasonable, MDSI may submit such dispute to be
      resolved by arbitration. The correction of any non Substantial Y2K Defects
      shall be the sole responsibility of DDS. For greater certainty any work
      done by DDS or MDSI UK employees to assist MDSI in the completion of the
      Copenhagen taxi project to the Site Acceptance Time and to assist MDSI in
      the completion of the RTL voice fall back functionality shall be deemed to
      be work that is solely attributable to MDSI for Y2K liability.

7.6.2 DDS shall respond to customer requests for support and/or maintenance
      related to Year 2000 Compliance issues within the time frames set out in
      the maintenance and support agreements included as Material Contracts. For
      greater certainty, DDS shall not be in breach of such response time
      obligations if it responds within the applicable time period, but is
      unable to resolve the defect because of a Substantial Y2K Defect. From
      December 1, 1999 through and including April 30, 2000 if DDS knows or
      suspects that a request for support or maintenance arises from a
      Substantial Y2K Defect (or after this date if DDS knows that a defect
      relates to a year 2000 compliance issue arising directly from the MDSI-TBU
      Software): (i) if there are any requests for support or maintenance

<PAGE>
                                      -30-


      under the Material Contracts, DDS shall notify MDSI of any such requests
      forthwith upon receiving the request from the customer; (ii) DDS shall
      also notify MDSI of DDS' response time in connection with such customer
      request and whether or not such response was within the time period set
      out in the applicable support and maintenance agreement; and (iii) DDS
      shall also notify MDSI of the particulars of the resolution of a customer
      request for support or maintenance where the request is related to a year
      2000 compliance issue arising directly from the MDSI-TBU Software. In
      addition to the foregoing, throughout this period DDS shall provide all
      disclosure to MDSI as reasonably requested by MDSI and MDSI shall be
      entitled, at its own expense, to have any of its employees or
      representatives attend any significant meetings or tests, provided that
      such attendance will be strictly in the capacity of an observer, and such
      employees or representatives shall not participate in or influence any
      discussions with the customer.

7.6.3 If at any time during the period beginning on December 1, 1999 to the end
      of the survival period of the representations and warranties under this
      Agreement, DDS can demonstrate that the MDSI-TBU Software contains a
      Substantial Y2K Defect:

      (a)   MDSI shall pay the costs to remedy any such Substantial Y2K Defect
            at the rate calculated in accordance with section 7.2 (or at MDSI's
            option, in full consultation with DDS, MDSI may perform such
            remedial work); and

      (b)   MDSI shall also indemnify DDS from and against any and all
            liabilities, claims, demands, costs, expenses, losses, damages,
            actions, causes of action and judgements whatsoever incurred or
            suffered by or asserted against DDS arising from any Substantial Y2K
            Defects, provided that DDS has not amended and shall not amend any
            provision relating to the limitation of liability in any Material
            Contract.

      If DDS has not amended the applicable limitation of liability provision in
      a Material Contract, MDSI may be liable for a Substantial Y2K Defect for
      an amount in excess of this limit of liability, if a court of competent
      jurisdiction delivers a final and non-appealable judgement that states
      that such limitation of liability is not enforceable. Any claims for
      indemnification by DDS under this section shall not be limited by the
      threshold limits set out in section 9.2 of this Agreement, but in all
      other respects the provisions of section 9 shall apply to any such claims.
      If any customer or other third party commences or threatens to commence
      any legal action against DDS arising from any such Substantial Y2K Defect,
      DDS shall immediately give written notice of the particulars of such
      action or threatened action to MDSI. Moreover where DDS wishes to rely
      upon the indemnification provisions set out in section 9 or otherwise make
      a claim for indemnity in connection with such Substantial Y2K Defect
      against MDSI, MDSI shall have the right to participate in and, to the
      extent it may wish to do so, assume the defence of such legal action in
      accordance with section 9.7. Notwithstanding the foregoing, in the year
      2000, if DDS discovers and demonstrates that there is a Substantial Y2K
      Defect in the MDSI-TBU Software supplied by MDSI to RTL, MDSI shall pay
      one half of the amount of any claim for loss of profits and/or liquidated
      damages relating to such Substantial Y2K Defect and DDS shall pay the
      other half of such amount. The correction of any non Substantial Y2K
      Defects shall be the sole responsibility of DDS.

7.7   DHL AP. If prior to the Closing Date MDSI is able to settle the
      outstanding account of $512,000 with DHL AP, MDSI shall keep all of the
      funds in connection with such settlement. If MDSI is not able to settle
      the outstanding accounts with DHL AP prior to the Closing Date, at Closing
      MDSI shall cause MDSI-UK to assign all rights to recover the account
      (including any documents reasonably required to assist MDSI in collecting
      such accounts) to MDSI so that MDSI may pursue the collection of the
      outstanding account after the Closing Date. For a period of 3 months from
      the Closing Date, MDSI shall attempt to settle this account amicably with
      DHL AP and accordingly MDSI will not threaten or commence legal action
      against DHL AP during this period to collect this outstanding account.
      After this 3 month period expires: if MDSI has not settled this account
      and DHL AP indicates that it is not prepared to continue to take delivery
      of products and services under the existing terms of its customer
      agreement with MDSI-UK, MDSI may commence legal action against DHL AP to
      collect this account; if DHL AP indicates that it is prepared to continue
      to take delivery of products and services under the existing terms of its
      customer agreement with MDSI-UK, DDS shall pay to MDSI MDSI's pro rata
      share of all funds received by DDS under this agreement, such share being
      (pound)86.44 per unit shipped.

<PAGE>
                                      -31-


7.8   Kolding Agreement. On or before Closing, MDSI shall procure from Kolding
      Taxi: (i) an assignment and transfer of the Kolding Taxi agreements from
      MDSI Software B.V. to MDSI UK; (ii) the agreement from Kolding Taxi that
      Kolding Taxi will not make claims under the existing bank guarantee for
      any breach relating to the failure to meet the delivery time schedule for
      the Kolding Taxi project; (iii) a signed written waiver or deletion of
      Kolding Taxi's right under section 23 of its Taxi Despatch supply contract
      with MDSI BV to terminate such contract; (iv) the proviso that if the taxi
      despatch system being supplied by MDSI UK to Kolding is not delivered by
      December 31, 1999, MDSI UK will provide a Y2K workaround for the existing
      taxi despatch system used by Kolding so that it can despatch orders, in a
      reasonable period of time prior to December 31, 1999, and that MDSI's UK's
      maximum liability with respect to the provision of such a workaround shall
      be limited to DKK 500.000 (as this is the current estimate of the price of
      such workaround). In consideration of MDSI supporting and causing to be
      maintained the bank guarantee referenced above, , DDS shall indemnify MDSI
      for any claims made by Kolding Taxi for breach of any of the agreements
      between Kolding Taxi and MDSI UK (such as for example, all penalties
      charged by Kolding for delay), other than the liability for the provision
      of the Y2K workaround described in 7.8 (iv) above (for which MDSI shall
      pay MDSI UK or DDS on a time and materials basis). MDSI's maximum
      liability for the provision of the workaround described in 7.8 (iv) above
      shall be limited to DKK 500,000. However, for greater certainty, MDSI
      shall remain liable to DDS for Substantial Y2K Defects for the MDSI-TBU
      Software supplied by MDSI to DDS at the Site Acceptance Time under the
      Copenhagen contract (as this is the MDSI-TBU Software which will be used
      by DDS in connection with the Kolding project). DDS will be responsible
      for any Y2K defects that arise from any changes made to the MDSI-TBU
      Software by or at the direction of DDS.

7.9   Source Code Escrow. DDS agrees that MDSI shall have the right, and DDS
      shall take all reasonable steps to ensure access to such right, to
      immediate access to and possession of the source code for all of the
      MDSI-TBU Software being acquired by DDS under this Agreement and all
      documentation related to such source code (the "Source Code", which Source
      Code is to be placed into escrow in connection with the Closing), so that
      MDSI can complete the Copenahagen Taxi project to the Site Acceptance
      Time, so that MDSI can take appropriate steps in the event that MDSI is
      required to take remedial steps to address Substantial Y2K Defects, and
      otherwise as specifically described in this Agreement, with respect to any
      of the MDSI-TBU Software after Closing. At Closing, the Source Code shall
      be placed into escrow with a mutually agreeable escrow agent, and the
      terms of the escrow agreement shall include the release conditions set out
      above.

7.10  Delivery of Consents, Etc. Each of the parties shall deliver all consents,
      authorizations and approvals of, and all filings, recordings and
      registrations with, any governmental authority or regulatory body or any
      other third party that are reasonably required in order to consummate of
      the Transaction, including, but not limited to, those consents set out at
      section II.6 of the Document List.

8. REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS TO SURVIVE CLOSING

8.1   All of the representations, warranties, covenants and agreements of the
      parties hereto contained in this Agreement will not merge on, and shall
      survive, the Closing and will continue in full force and effect for the
      benefit of DDS and MDSI. Except as specifically set out or contemplated in
      certain representations, warranties, covenants and agreements contained
      elsewhere in this Agreement (any such provisions being "Excepted
      Provisions", which will continue in full force and effect for the benefit
      of DDS or MDSI, as the case may be, in accordance with the terms thereof,
      such as the provisions relating to taxes and grants), the representations,
      warranties, covenants and agreements contained in this Agreement shall
      survive for a period of three years from the Closing Date.

9. INDEMNIFICATION

9.1   Mutual Indemnification. DDS and MDSI (the "Indemnifying Party") each
      mutually covenant and agree to indemnify the other (the "Indemnified
      Party") against all liabilities, claims, demands, actions, causes of
      action,

<PAGE>
                                      -32-


      damages, losses, costs or expenses suffered or incurred by or asserted
      against the Indemnified Party (each being referred to as a "Claim"),
      directly or indirectly, by reason of or arising out of:

      (a)   a breach of any warranties or representations on the part of the
            Indemnifying Party herein contained or contained in any of the Other
            Agreements; and

      (b)   a breach of any agreement, term or covenant on the part of the
            Indemnifying Party made or to be observed or performed pursuant
            hereto or pursuant to any of the Other Agreements.

      The amount of any Claim shall bear interest at a fixed rate of interest of
      8% per annum (the "Claim Rate"), calculated from and after the date such
      Claim is incurred or suffered by or asserted against the Indemnified Party
      to the date payment in full is made by the Indemnifying Party.

9.2   Limitations. No claim for indemnity shall be made pursuant to the forgoing
      section 9.1 unless and until the aggregate amount of all Claims to be made
      by the Indemnified Party equals $100,000 or more (the "Threshold Amount"),
      and each individual Claim included in such Threshold Amount must equal at
      least $10,000 (an "Eligible Claim") in order to be included in such
      Threshold Amount, however, after its aggregate Eligible Claims equal or
      exceed the Threshold Amount the Indemnified Party shall be entitled to
      indemnification in respect of the full amount of any such Eligible Claims.

9.3   MDSI Liability Re: MDSI-TBU Customer Contracts. As set out and
      contemplated in section 2.4 and except as specifically set out herein,
      from and after the time of Closing, MDSI shall not be responsible for any
      liabilities or obligations arising under any customer contracts or
      commitments of MDSI-TBU, all of which contracts and commitments MDSI
      confirms are listed in Schedule "D" and complete and accurate copies of
      which (disclosing all such liabilities and obligations) MDSI confirms it
      has provided to DDS. Subject to the limitations set out at section 9.2
      above, if after the time of Closing, any customer of MDSI-TBU claims and
      proves that MDSI or any of its affiliates had an obligation under the
      aforementioned contracts which was not disclosed to DDS, MDSI shall be
      responsible for and shall indemnify and hold harmless DDS for the amount
      of such claim.

9.4   Set-Off. DDS shall also be entitled (in addition to the foregoing right to
      indemnification or any other rights or remedies of DDS) to set-off against
      or make a reduction against any amount or amounts owing or payable by DDS
      to MDSI (including without limitation any amounts owing or payable
      pursuant to the Promissory Note), the amount of any Claim described in
      Section 9.1, together with interest thereon at the Claim Rate calculated
      from and after the date such Claim is incurred by or asserted against DDS
      to the date upon which set-off or payment so reduced is made by DDS. If at
      any time, any Claim referred to in this section 9.4 (plus interest
      thereon) exceeds the amount or amounts owing by DDS to MDSI, DDS shall
      have a general claim against MDSI for the payment of such excess and MDSI
      shall pay such excess to DDS forthwith upon written notification by DDS.
      MDSI shall also be entitled (in addition to the foregoing right to
      indemnification or any other rights or remedies of MDSI) to set-off
      against or make a reduction against any amount or amounts owing or payable
      by MDSI to DDS, the amount of any Claim described in Section 9.1, together
      with interest thereon at the Claim Rate calculated from and after the date
      such Claim is incurred by or asserted against MDSI to the date upon which
      set-off or payment so reduced is made by MDSI. If at any time, any Claim
      referred to in this section 9.4 (plus interest thereon) exceeds the amount
      or amounts owing by MDSI to DDS, MDSI shall have a general claim against
      DDS for the payment of such excess and DDS shall pay such excess to MDSI
      forthwith upon written notification by MDSI.

9.5   Expiry. The right of an Indemnified Party to indemnification or the right
      of DDS or MDSI to set-off under this Article 9 shall terminate on the date
      which is exactly three years following the Closing Date or, in the case of
      any Excepted Provision, on the date when such obligation terminates in
      accordance with the terms thereof (the "Expiry Date"), unless on or prior
      to the Expiry Date the Indemnified Party gives notice to the Indemnifying
      Party pursuant to section 9.6 of its intention to seek indemnification or
      set-off.

9.6   Notice. If an Indemnified Party intends to exercise its right of
      indemnification or set-off, it shall first give written notice thereof to
      the Indemnifying Party (a "9.6 Notice"), setting forth therein particulars
      of the nature of the

<PAGE>
                                      -33-


      Claim and estimated quantum of damages and attaching all relevant
      documentation in support of such Claim. The Indemnifying Party shall have
      15 days after receipt of the 9.6 Notice to pay or remedy the Claim,
      provided that if the Claim cannot, in the reasonable opinion of the
      Indemnifying Party by its nature be remedied within such 15 day period,
      the Indemnifying Party shall have up to a maximum of a further 45 days to
      remedy the Claim, if it proceeds immediately after receipt of the 9.6
      Notice and continues with all due diligence to take the necessary remedial
      action. Any such 9.6 Notice shall be final and binding on the Indemnifying
      Party, and the Indemnifying Party shall be deemed to agree to indemnify
      the Indemnified Party (or to set-off against any amount owing by the
      Indemnifying Party to the Indemnified Party, as the case may be) in
      respect of the amounts indicated in such 9.6 Notice, unless, within 15
      days of receipt of such 9.6 Notice, written notice of objection is given
      by the Indemnifying Party to the Indemnified Party. If notice of objection
      is given pursuant to this section 9.6, the Indemnifying Party and the
      Indemnified Party shall consult with one another with respect to the
      objection. If the foregoing parties are not able to reach agreement within
      15 days after the notice of objection is given, the dispute shall be
      resolved by an independent arbitrator, to be agreed upon by such parties.
      If no agreement concerning the identity of the arbitrator is reached
      within 30 days after the notice of objection is given, either of the
      Indemnifying Party or the Indemnified Party may apply to a court of
      competent jurisdiction for an order, under the Commercial Arbitration Act
      (British Columbia) or any successor legislation thereto, appointing an
      independent arbitrator. The resolution of the dispute, including the issue
      of responsibility for costs in respect of the arbitration and any motions
      to appoint the arbitrator, shall be provided by the independent arbitrator
      in a written decision to be delivered simultaneously to the Indemnifying
      Party and the Indemnified Party, which decision shall be final and binding
      on the parties and shall not be subject to appeal or judicial review.

9.7   Third Party Claims. Notwithstanding the provisions of section 9.6,
      promptly after receiving notice of any action, suit, proceeding or claim
      against an Indemnified Party or receipt of notice of the commencement of
      any investigation which is based, directly or indirectly, upon any matter
      in respect of which indemnification may be sought from the Indemnifying
      Party (a "Third Party Claim"), such Indemnified Party will notify the
      Indemnifying Party in writing of the particulars thereof, will provide
      copies of all relevant documentation to the Indemnifying Party and, unless
      the Indemnifying Party assumes the defence thereof, will keep the
      Indemnifying Party advised of the progress thereof and will discuss all
      significant actions proposed. The omission so to notify the Indemnifying
      Party shall relieve the Indemnifying Party of any liability which the
      Indemnifying Party may have to the Indemnified Party under this Agreement.
      The Indemnifying Party shall be entitled, at its own expense, to
      participate in and, to the extent it may wish to do so, assume the defence
      of any Third Party Claim, provided such defence is conducted by
      experienced and competent counsel. Upon the Indemnifying Party notifying
      the Indemnified Party in writing of the Indemnifying Party's election to
      assume the defence and retaining counsel, the Indemnifying Party shall not
      be liable to the Indemnified Party for any legal expenses subsequently
      incurred by the Indemnified Party in connection with such defence. If such
      defence is assumed by the Indemnifying Party, the Indemnifying Party
      throughout the course thereof will provide copies of all relevant
      documentation to the Indemnified Party, will keep the Indemnified Party
      advised of the progress thereof and will discuss with the Indemnified
      Party all significant actions proposed. Notwithstanding the foregoing, any
      Indemnified Party shall have the right, at the Indemnifying Party's
      expense (except as specifically set out in (iii) below), to employ counsel
      of such Indemnified Party's choice, in respect of the defence of any Third
      Party Claim if: (i) the employment of such counsel has been authorized by
      the Indemnifying Party; or (ii) the Indemnifying Party has not assumed the
      defence and employed counsel therefor within a reasonable time after
      receiving notice of such Third Party Claim; or (iii) counsel retained by
      the Indemnifying Party or the Indemnified Party has advised the
      Indemnified Party that representation of both parties by the same counsel
      would be inappropriate because there may be legal defences available to
      the Indemnified Party which are different from or in addition to those
      available to the Indemnifying Party (in which event and to that extent,
      the Indemnified Party shall be responsible for its own expenses and the
      Indemnifying Party shall not have the right to assume or direct the
      defence on the Indemnified Party's behalf) or that there is a conflict of
      interest between the Indemnifying Party and the Indemnified Party (in
      which event the Indemnifying Party shall not have the right to assume or
      direct the defence on the Indemnified Party's behalf). No admission of
      liability and no settlement of any Third Party Claim shall be made without
      the consent of the Indemnified Party affected, such consent not to be
      unreasonably withheld. No admission of liability shall be made and the
      Indemnifying Party shall not be liable for any settlement of any Third
      Party Claim made without its consent, such consent not to be unreasonably
      withheld.

9.8   Postponement of Amounts Payable. During the period from and after the date
      a 9.6 Notice is given to and including the date the Claim is paid,
      set-off, remedied or resolved by agreement or arbitration, the payment of
      any amount which becomes due by the Indemnified Party to the Indemnifying
      Party hereunder, under any of the Other Agreements or otherwise shall be
      postponed; PROVIDED THAT any amount so postponed shall bear interest at
      the Claim Rate calculated from and after the date such amount was
      otherwise due to and including the date upon which the Claim giving rise
      to such postponement is paid, set-off, remedied or resolved. For greater
      certainty, to the extent that any amount is validly set off from any other
      amount so postponed, interest shall only be calculated and owing on the
      net amount.

9.9   No Indemnity for Negligence of Indemnified Party. Notwithstanding any of
      the foregoing provisions in this section 9, this right of indemnity shall
      not apply to the extent that an arbitrator or a court of competent
      jurisdiction in a final judgment that has become non-appealable shall
      determine that such expenses, losses, claims, actions, damages or
      liabilities to which the Indemnified Party may be subject were directly
      caused by the negligence or willful misconduct of the Indemnified Party or
      the breach of this Agreement or any of the Other Agreements by the
      Indemnified Party.
