                               PROSPECTUS SUMMARY

    You should read the following summary together with the more detailed
information about us and our common stock being sold in this offering and our
consolidated financial statements and the notes to those statements appearing
elsewhere in this prospectus.

                                  Our Business

    Entrust Technologies is the leading global provider of public-key
infrastructure, or PKI, products and services to e-businesses and other
organizations. Unlike products and services that focus primarily upon the
issuance of digital certificates, which are similar to electronic passports,
our award-winning solution is a comprehensive, end-to-end PKI framework
designed to assure the security of electronic transactions and communications
over advanced networks, including the Internet. Our open, scalable software
solution operates across multiple platforms, network devices and applications.
According to International Data Corporation, the worldwide market for PKI-based
products and services is expected to grow from $122.7 million in 1998 to $1.3
billion in 2003. Since 1994, we have provided our PKI solution primarily to
global enterprises and government entities, including Citibank, FedEx, MCI
Worldcom, NASA, the United Kingdom Post Office and the Canadian Department of
National Defense. To date, over four million users worldwide have been licensed
to use Entrust products.

    Our PKI solution is particularly relevant to organizations in the growing
business-to-business, or B2B, electronic commerce market. We offer B2B
organizations a comprehensive security solution that includes the robust
functionality required to support their increasingly advanced and high-value
electronic transactions and communications. We believe that we are well-
positioned to capitalize on our PKI market leadership to address B2B and other
important markets, such as the business-to-consumer, or B2C, market. We are
also actively developing additional functionality to address emerging
opportunities, such as the growing need to secure e-business transactions
conducted over wireless networks.

                             Our Market Opportunity

    The widespread adoption in recent years of public and private networks has
revolutionized the manner in which organizations communicate and conduct
business. Businesses are increasingly relying on these networks to conduct
complex transactions and communicate confidential information, both internally
and with other businesses. However, there are important information security
concerns relating to these electronic interactions, such as the risk of theft,
alteration, interception or dissemination of confidential data, fraud, loss of
reputation and economic loss.

    Although a wide range of products, such as firewalls and password tokens,
were introduced to address network security concerns, the limitations inherent
in these solutions led to the development of public-key encryption and digital
certification systems. However, these systems are only partial solutions and do
not address the management and business issues critical to maintaining an
effective security environment. To address these issues, organizations,
particularly those in the B2B market, must have a robust public-key
infrastructure that provides full life-cycle management of public and private
keys, including issuance, authentication, storage, retrieval, backup, recovery,
updating and revocation. In addition, these functions must operate in an easy-
to-use, scalable and cost-effective manner.

                                  Our Solution

    Our PKI solution provides for the flexible management of network security
features, while offering the complete functionality necessary for full life-
cycle management of public keys and digital certificates. Our products and
services support multiple certificate types and configurations, including:

  . multi-application certificates for use across a wide range of
    applications;

  . Web certificates for secure Web transactions;

  . virtual private networking certificates, or VPN certificates, for secure
    network communications; and

  . wireless certificates for devices such as cellular telephones and pagers.

    Our products can support large numbers of simultaneous users, while
seamlessly performing complex certification and key management functions that
allow organizations to significantly reduce their overall costs for addressing
security requirements.

                                  Our Strategy

    Our objective is to maintain and enhance our position as the leading global
provider of comprehensive, end-to-end PKI products and services that enable
organizations to effectively manage secure transactions and communications
across a wide range of applications. Key elements of our strategy include the
following:

  . capitalize on B2B market opportunities;

  . pursue wireless opportunities;

  . maintain product leadership and increase brand recognition;

  . expand and leverage strategic relationships;

  . further penetrate B2C market; and

  . leverage global presence.

                                  Our History

    We were originally established in January 1994 as the Secure Networks group
of Nortel Networks Corporation and its subsidiary, Nortel Networks Inc., to
pursue the development and sale of PKI products and services, and were
incorporated as a Maryland corporation in December 1996. Our principal
executive offices are located at One Preston Park South, 4975 Preston Park
Boulevard, Suite 400, Plano, Texas 75093, and our telephone number at that
location is (972) 943-7300. We also have offices in Canada, the United Kingdom,
Switzerland, Germany and Japan, as well as additional offices in the United
States.

                                  RISK FACTORS

    This offering involves a high degree of risk. You should consider carefully
the risks and uncertainties described below and the other information in this
prospectus, including our consolidated financial statements and related notes,
before deciding to invest in shares of our common stock. If any of the
following risks or uncertainties actually occurs, our business, financial
condition and operating results would likely suffer. In that event, the market
price of our common stock could decline and you could lose all or part of the
money you paid to buy our common stock.

          Risks Relating To Our Financial Condition and Business Model

Our quarterly revenues and operating results are subject to significant
fluctuations and such fluctuations may lead to a reduced market price for our
stock

    Our quarterly revenues and operating results have varied in the past and
may continue to fluctuate in the future. We believe that period-to-period
comparisons of our operating results are not necessarily meaningful, but
securities analysts and investors often rely upon these comparisons as
indicators of future performance. If our operating results in any future period
fall below the expectations of securities analysts and investors, the market
price of our securities would likely decline. Factors that have caused our
results to fluctuate in the past and which are likely to affect us in the
future include the following:

  . length of sales cycles associated with our product offerings;

  . the timing, size and nature of our licensing transactions;

  . market acceptance of new products or product enhancements by us or our
    competitors;

  . the relative proportions of revenues derived from licenses and services
    and maintenance;

  . the timing of new personnel hires and the rate at which new personnel
    become productive;

  . changes in pricing policies by our competitors;

  . changes in our operating expenses; and

  . fluctuations in foreign currency exchange rates.

Estimating future revenues is difficult, and our failure to do so accurately
may lead to a reduced market price for our stock and reduced profitability

    Estimating future revenues is difficult because we ship our products soon
after an order is received and, as such, we do not have a significant backlog.
Thus, quarterly license revenues depend heavily upon orders received and
shipped within the same quarter. Moreover, we historically have recorded 60% to
80% of our total quarterly revenues in the third month of the quarter, with a
concentration of revenues in the second half of that month. We expect that this
concentration of revenues, which is attributable in part to the tendency of
some customers to make significant capital expenditures at the end of a fiscal
quarter and to sales patterns within the software industry, will continue for
the foreseeable future.

    Our expense levels are based, in significant part, upon our expectations as
to future revenues and are largely fixed in the short term. We may be unable to
adjust spending in a timely manner to compensate for any unexpected shortfall
in revenues. Any significant shortfall in revenues in relation to our
expectations could have an immediate and significant effect on our
profitability for that quarter and may lead to a reduced market price for our
stock.

Because of the lengthy and unpredictable sales cycle associated with our large
PKI transactions, we may not succeed in closing transactions on a timely basis
or at all, which would adversely affect our revenues and operating results

    Transactions for our PKI solution often involve large expenditures, and the
sales cycles for these transactions are often lengthy and unpredictable.
Factors affecting the sales cycle include:

  . customers' budgetary constraints;

  . the timing of customers' budget cycles; and

  . customers' internal approval processes.

    We may not succeed in closing such large transactions on a timely basis or
at all, which could cause significant variability in our revenues and results
of operations for any particular period. If our results of operations and cash
flows fall below the expectations of securities analysts, our stock price may
decline.

A limited number of customers has accounted for a significant percentage of our
revenues, which may decline if we cannot keep or replace these customer
relationships

    Historically, a limited number of customers has accounted for a significant
percentage of our revenues. In 1997, three customers accounted for 19%, 12% and
11% of revenues, respectively. In 1998, our three largest customers accounted
for 23% of revenues. In 1999, our three largest customers accounted for 31% of
revenues, with the largest customer accounting for 23% of revenues. We
anticipate that our results of operations in any given period will continue to
depend to a significant extent upon revenues from a small number of customers.
In addition, we anticipate that such customers will continue to vary over time,
so that the achievement of our long-term goals will require us to obtain
additional significant customers on an ongoing basis. Our failure to enter into
a sufficient number of large licensing agreements during a particular period
could have a significant adverse effect on our revenues.

              Risks Relating to Our Markets, Products and Strategy

If the e-business security market does not continue to grow, demand for our
products and services will be adversely affected

    The market for e-business security solutions is at an early stage of
development. Continued growth of the e-business security market will depend, in
large part, on the following:

  . the continued expansion of Internet usage and the number of
    organizations adopting or expanding intranets and extranets;

  . the ability of network infrastructures to support an increasing number
    of users and services;

  . the public recognition of the potential threat posed by computer hackers
    and other unauthorized users; and

  . the continued development of new and improved services for
    implementation across the Internet, intranets and extranets.

    A decline in the growth of this market could reduce demand for our
products, adversely affecting our revenues and results of operations.

                                       8
<PAGE>

A breach of security at one of our customers, whether or not due to our
products, could harm our reputation and reduce the demand for our products

    The processes used by computer hackers to access or sabotage networks and
intranets are rapidly evolving. A well-publicized actual or perceived breach of
network or computer security at one of our customers, regardless of whether
such breach is attributable to our products, or any significant advance in
techniques for decoding or "cracking" encrypted information, could adversely
affect the market's perception of us and our products, and could have an
adverse effect on our reputation and the demand for our products.

If our products contain errors or bugs, sales of our products would likely
decline

    Our products may contain errors, failures or bugs that our existing testing
procedures have not detected. The errors may become evident at any time during
the life of our products. The discovery of any errors, failures or bugs in any
products may result in:

  . adverse publicity;

  . product returns;

  . the loss or delay of market acceptance of our products; and

  . third-party claims against us.

    Accordingly, the discovery of any errors, failures or bugs would have a
significant adverse effect on the sales of our products.

Our revenues may decline if we cannot compete successfully in an intensely
competitive market

    We target our products at the rapidly evolving market for e-business
security solutions. Many of our current and potential competitors have longer
operating histories, greater name recognition, larger installed bases and
significantly greater financial, technical, marketing and sales resources than
we do. As a result, they may be able to react more quickly to emerging
technologies and changes in customer requirements, or to devote greater
resources to the promotion and sale of their products. In addition, certain of
our current competitors in particular segments of the security marketplace may
in the future broaden or enhance their offerings to provide a more
comprehensive solution competing more fully with our functionality.

    Increased competition, as well as consolidation of competitors, could
result in lower prices, reduced margins or the failure of our products and
services to achieve or maintain market acceptance, any of which could have a
serious adverse effect on our business, financial condition and results of
operations. See "Business--Competition" for a list of our competitors.

Our business will not be successful if we do not keep up with the rapid changes
in our industry

    The emerging market for e-business security products and related services
is characterized by rapid technological developments, frequent new product
introductions and evolving industry standards. To be competitive, we have to
continually improve the performance, features and reliability of our products
and services, particularly in response to competitive offerings, and be first
to market with new products and services or enhancements to existing products
and services. Our failure to develop and introduce new products and services
successfully on a timely basis and to achieve market acceptance for such
products and services could have a significant adverse effect on our business,
financial condition and results of operations.

We may have difficulty managing our expanding operations, which could adversely
affect our ability to successfully grow our business

    The growth in the size and complexity of our business over the past few
years has placed a significant strain on our managerial, operational and
financial resources. Our ability to manage future growth, if any, will depend
upon our ability to:

  . continue to implement and improve operational, financial and management
    information systems on a timely basis; and

  . expand, train, motivate and manage our work force.

    Our personnel, systems, procedures and controls may not be adequate to
support our operations. The geographic dispersal of our operations, including
the separation of our headquarters in Plano, Texas, from our research and
development facility in Ottawa, Canada, may make it more difficult to manage
our growth.

If we fail to continue to attract and retain qualified personnel, our business
may be harmed

    Our future success depends upon our ability to continue to attract and
retain highly qualified scientific, technical, sales and managerial personnel.
Competition for such personnel is intense, particularly in the field of
cryptography, and there can be no assurance that we can retain our key
scientific, technical, sales and managerial employees or that we can attract,
motivate or retain other highly qualified personnel in the future. If we cannot
retain or are unable to hire such key personnel, our business, financial
condition and results of operations could be significantly adversely affected.

Future acquisitions or investments could disrupt our ongoing business, distract
our management and employees, increase our expenses and adversely affect our
results of operations

    It is possible, as part of our future growth strategy, that we will from
time-to-time acquire or make investments in companies, technologies, product
solutions or professional services offerings. With respect to these
acquisitions, we would face the difficulties of assimilating personnel and
operations from the acquired businesses and the problems of retaining and
motivating key personnel from such businesses. In addition, these acquisitions
may disrupt our ongoing operations, divert management from day-to-day business,
increase our expenses and adversely impact our results of operations. Any
future acquisitions would involve certain other risks, including the assumption
of additional liabilities, potentially dilutive issuances of equity securities
and incurrence of debt. In addition, these types of transactions often result
in charges to earnings for such items as amortization of goodwill or in-process
research and development expenses.

We face risks associated with our international operations and plans for
expansion, which, if not managed properly, could have a significant adverse
effect on our business, financial condition or results of operations

    In the future, we may establish additional foreign operations, hire
additional personnel and establish relationships with additional partners
internationally. This expansion would require significant management attention
and financial resources and could have an adverse effect on our business,
financial condition and results of operations. Although our international sales
currently are primarily denominated in U.S. dollars, we may increasingly
denominate sales in foreign currencies in the future. In addition, our
international business may be subject to the following risks:

  . difficulties in collecting international accounts receivable;

  . difficulties in obtaining U.S. export licenses, especially for products
    containing encryption technology;

                                       10
<PAGE>

  . potentially longer payment cycles for customer payments;

  . increased costs associated with maintaining international marketing
    efforts;

  . introduction of non-tariff barriers and higher duty rates;

  . difficulties in enforcement of contractual obligations and intellectual
    property rights;

  . difficulties managing personnel and operations in remote locations; and

  . increased complexity in global corporate tax structure.

    Any one of these could significantly and adversely affect our business,
financial condition or results of operations.

                      Risks Relating to Legal Uncertainty

If the laws regarding exports of our products further limit or otherwise
restrict our business, we could be prohibited from shipping our products to
restricted countries, which would result in a loss of revenues

    Some of our products are subject to export controls under laws of the U.S.,
Canada and other countries. The list of products and countries for which
exports are restricted, and the relevant regulatory policies, are likely to be
revised from time to time. If we cannot obtain required government approvals
under these regulations, we may not be able to sell products abroad or make
products available for sale internationally via computer networks such as the
Internet. Furthermore, U.S. governmental controls on the exportation of
encryption products and technology may in the future restrict our ability to
freely export some of our products with the most powerful information security
encryption technology. See "Business--Regulatory Matters" for a discussion of
our regulatory environment.

We may not be able to protect our intellectual property rights, which could
make us less competitive and cause us to lose market share

    Our future success will depend, in part, upon our intellectual property
rights and our ability to protect these rights. We rely on a combination of
patent, copyright, trademark and trade secret laws, nondisclosure agreements,
shrink-wrap licenses and other contractual provisions to establish, maintain
and protect our proprietary rights. Despite our efforts to protect our
proprietary rights, unauthorized third parties may:

  . copy aspects of our products;

  . obtain and use information that we regard as proprietary; or

  . infringe upon our patents.

    Policing piracy and other unauthorized use of our products is difficult,
particularly in international markets and as a result of the growing use of the
Internet. In addition, third parties might successfully design around our
patents or obtain patents that we would need to license or design around.
Finally, the protections we have obtained may not be sufficient because:

  . some courts have held that shrink-wrap licenses, because they are not
    signed by the licensee, are not enforceable;

  . our trade secrets, confidentiality agreements and patents may not
    provide meaningful protection of our proprietary information; and

                                       11
<PAGE>

  . we may not seek additional patents on our technology or products and
    such patents, even if obtained, may not be broad enough to protect our
    technology or products.

    Our inability or failure to protect our proprietary rights could have a
significant adverse effect on our business, financial condition or results of
operations.

We have been subject to, and may in the future become subject to, intellectual
property infringement claims that could be costly and could result in a
diversion of management's attention

    As the number of security products in the industry increases and the
functionality of these products further overlaps, software developers and
publishers may increasingly become subject to claims of infringement or
misappropriation of the intellectual property or proprietary rights of others.
Surety Technologies, Inc. asserted an unsuccessful patent infringement claim
against us in February 1999, and third parties may assert infringement or
misappropriation claims against us in the future. Defending or enforcing our
intellectual property could be costly and could result in a diversion of
management's attention, which could have a significant adverse effect on our
business, financial condition or results of operations. A successful claim
against us could also have a significant adverse effect on our results of
operations for the period in which damages are paid.

We may lose access to technology that we license from outside vendors, which
loss could adversely affect our ability to sell our products

    We rely on outside licensors for patent and/or software license rights in
encryption technology that is incorporated into and is necessary for the
operation of our products. For example, we license encryption technology that
is fundamental to our product from RSA Security Inc., which holds a patent for
this technology that expires in September 2000. We recently received
correspondence from RSA indicating that it believes that, as of November 1999,
we were no longer properly licensed to use this patent. While we strongly
believe that RSA's assertion is without merit, we cannot assure you of the
outcome of our discussions with RSA about this matter. An adverse outcome could
subject us to significant additional licensing fees, money damages or other
legal relief. In January 2000, RSA filed a complaint against us with respect to
this matter but did not serve notice, and subsequently withdrew, the complaint.
There can be no assurance that RSA will not institute litigation against us
with respect to this matter in the future. In addition, our ability to provide
Web server certificates is currently dependent upon a licensing agreement we
have with Thawte Consulting (Pty.) of South Africa, whose sale to VeriSign,
Inc., one of our primary competitors, is pending. Our success will depend in
part on our continued ability to have access to such technologies that are or
may become important to the functionality of our products. Any inability to
continue to procure or use such technology could have a significant adverse
effect on our ability to sell some of our products.

                        Risks Relating to this Offering

Our management may invest or spend the proceeds of this offering in ways which
may not benefit the business

    Our management will retain broad discretion to allocate the proceeds of
this offering. Management's failure to apply these funds effectively could have
an adverse effect on our ability to implement our strategy.

Our stock price is volatile and may continue to be volatile in the future,
which could result in substantial losses for investors purchasing shares in
this offering

    The trading price of our common stock has been, and is expected to continue
to be, highly volatile and may be significantly and adversely affected by
factors such as:

  . actual or anticipated fluctuations in our operating results;

  . announcements of technological innovations;

                                       12
<PAGE>

  . new products or new contracts by us or our competitors;

  . developments with respect to patents, copyrights or propriety rights;

  . conditions and trends in the security industry;

  . changes in financial estimates by securities analysts; and

  . general market conditions and other factors.

Nortel Networks will be able to exercise substantial influence over all matters
requiring stockholder and board approval and could make decisions about our
business that conflict with the interests of other stockholders

    Upon completion of this offering, Nortel Networks Corporation, directly and
indirectly through its subsidiary, Nortel Networks Inc., will beneficially own
approximately 33.3% of our outstanding voting stock, and two of our eight
directors will be representatives of Nortel Networks. Accordingly, Nortel
Networks will continue to have the ability to exert significant influence over
our affairs, including the election of directors and decisions relating to our
strategic and operating activities. This concentration of ownership and board
representation may have the effect of delaying or preventing a change in
control that other stockholders may find favorable.

Provisions of our charter and bylaws may delay or prevent transactions that are
in your best interests

    Our charter and bylaws contain provisions, including a staggered board of
directors, that may make it more difficult for a third party to acquire us, or
may discourage bids to do so. These provisions could limit the price that
investors might be willing to pay for shares of our common stock and could make
it more difficult for a third party to acquire, or could discourage a third
party from acquiring, a majority of our outstanding voting stock. Our board of
directors also has the authority to issue up to 5,000,000 shares of preferred
stock and to determine the price, rights, preferences, privileges and
restrictions, including voting rights, of those shares without any further vote
or action by the stockholders. The rights of the holders of common stock will
be subject to, and may be adversely affected by, the rights of the holders of
any preferred stock that may be issued in the future. The issuance of preferred
stock could make it more difficult for a third party to acquire, or may
discourage a third party from acquiring, a majority of our outstanding voting
stock.

              CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

    This prospectus contains forward-looking statements within the meaning of
the Private Securities Litigation Reform Act of 1995 concerning our business,
operations and financial condition. You can identify these statements by words
such as "expects", "anticipates", "intends", "plans", "believes", "seeks",
"estimates" and similar expressions. Because these forward-looking statements
involve risks and uncertainties, actual results could differ materially from
those expressed or implied by these forward-looking statements for a number of
important reasons, including those discussed under "Risk Factors",
"Management's Discussion and Analysis of Financial Condition and Results of

                                USE OF PROCEEDS

    We estimate that we will receive net proceeds of approximately $96.5
million from our sale of 1,875,000 shares of common stock in this offering, at
an assumed public offering price of $54.125 per share and after deducting the
estimated underwriting discounts and commissions and estimated offering
expenses. If the underwriters' over-allotment option is exercised in full, we
estimate that our net proceeds will be approximately $112.4 million. We will
not receive any proceeds from the sale of shares of common stock by the selling
stockholders.

    We intend to use the net proceeds of this offering for working capital and
other general corporate purposes, including product development. We may also
use a portion of the net proceeds to acquire or invest in complementary
companies, product lines, products or technologies. Except as described below,
we do not have any agreements or commitments with respect to any acquisition or
investment and we are not involved in any negotiations with respect to any
acquisition or investment. We are currently in negotiations to acquire a
professional services firm for up to $16.0 million in cash. Any acquisition is
subject to the execution of a definitive purchase agreement and customary
closing conditions. Pending the use of net proceeds described above, we intend
to invest net proceeds in short-term, investment grade, interest-bearing
securities.

                            RECENT FINANCIAL RESULTS

    On January 18, 2000, we announced the following unaudited condensed
consolidated financial data for the three months and years ended December 31,
1998 and 1999 and as of December 31, 1998 and 1999. In the opinion of
management, the unaudited condensed consolidated financial data presented below
have been prepared on a basis consistent with our audited consolidated
financial statements and include all adjustments, consisting only of normal
recurring adjustments, necessary for a fair presentation of our results of
operations for those periods. The data set forth below should be read in

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

    The following discussion and analysis of our financial condition and
results of operations should be read in conjunction with "Selected Consolidated
Financial Data" and our consolidated financial statements and notes thereto
appearing elsewhere in this prospectus. This discussion and analysis contains
forward-looking statements that involve risks, uncertainties and assumptions.
Our actual results may differ materially from those anticipated in these
forward-looking statements as a result of certain factors, including those set
forth under "Risk Factors" and elsewhere in this prospectus.

Overview

    We are the leading global provider of PKI products and services to e-
businesses and other organizations. We are committed to enabling businesses to
conduct e-commerce securely, ensuring they benefit from increased service
efficiency, technology cost savings and the confidence associated with trusted
e-business technologies. Our products and services enable organizations and
their partners to manage trusted, secure electronic transactions and
communications over today's advanced networks, including intranets, extranets
and the Internet.

    We were originally established in January 1994 as the Secure Networks group
of Nortel Networks Corporation to pursue the development and sale of PKI
products. During December 1996, Nortel Networks restructured its Secure
Networks group by incorporating Entrust Technologies Inc. in Maryland and
Entrust Technologies Limited in Ontario, Canada. As a result of the
restructuring and concurrent private placement, the assets and business of the
Secure Networks group were transferred to the newly incorporated companies, and
Entrust Technologies Inc. became a majority-owned subsidiary of Nortel Networks
and Entrust Technologies Limited became a majority-owned subsidiary of Entrust
Technologies Inc. In 1998, Entrust Technologies (UK) Limited was incorporated
in the United Kingdom as a wholly owned subsidiary of Entrust Technologies Inc.
In June 1998, we acquired 100% ownership of r3 Security Engineering AG, a
professional services organization specializing in electronic security
consulting, located in Switzerland. We completed our initial public offering of
common stock in August 1998. In 1999, we incorporated two additional, wholly
owned European subsidiaries, Entrust Technologies GmbH in Germany and Entrust
Technologies S.A.R.L. in France. Additionally, at the end of November 1999, we
reorganized our r3 business in Switzerland and formed Entrust Technologies
(Switzerland) Ltd. Liab. Co.

    We recognize revenues in accordance with the provisions of the American
Institute of Certified Public Accountants' Statement of Position 97-2 "Software
Revenue Recognition". We generate revenues primarily from licensing the rights
to our software products to end users and, to a lesser extent, from sublicense
fees from resellers. We also generate revenues from consulting, training and
post-contract support, or maintenance, performed for customers who license our
products.

    Accordingly, revenues from perpetual software license agreements are
recognized as revenues upon receipt of an executed license agreement, or an
unconditional order under an existing license agreement, and shipment of the
software, if there are no significant remaining vendor obligations, collection
of the receivable is probable and payment is due within twelve months.

    Revenues from maintenance services are recognized ratably over the term of
the maintenance period, which is typically one year. If maintenance services
are included free of charge or discounted in a license agreement, such amounts
are unbundled from the license fee at their fair market value based upon the
value established by independent sales of such maintenance services to other
customers. Revenues from the sale of Web server certificates by Entrust.net,
our certification authority service, are also recognized ratably over the term
of the certificate, which is typically one to two years.

                                       18
<PAGE>

    Consulting and training revenues are generally recognized as the services
are performed. Consulting services are typically performed under separate
service agreements and are usually performed on a time and materials basis.
Such services primarily consist of implementation services related to the
installation and deployment of our products and do not include significant
customization or development of the underlying software code.

    We use the percentage of completion method to account for large custom
development contracts. Under this method, we recognize revenues and profit as
the work on the contract progresses. Revenues are recognized by applying the
percentage of the total cost incurred to date divided by the total estimated
contract cost to the total contract value, and any projected loss is recognized
immediately. The project cost estimates in each case are reviewed on a regular
basis.

Nine Months Ended September 30, 1998 and 1999

  Revenues

    Total Revenues. Total revenues increased 74% from $34.0 million for the
nine months ended September 30, 1998 to $59.2 million for the nine months ended
September 30, 1999. Total revenues derived from North America increased 94%
from $26.1 million for the nine months ended September 30, 1998 to $50.7
million for the nine months ended September 30, 1999, while total revenues
derived from outside of North America increased 8% from $7.9 million for the
nine months

                                       19
<PAGE>

ended September 30, 1998 to $8.5 million for the nine months ended September
30, 1999. Although the majority of the overall growth in total revenues in 1999
has been experienced in North America, we have also focused on growing our
revenue base internationally, particularly in Europe and Asia. However, the
level of non-North American revenues has fluctuated from period to period and
is expected to continue that trend in the foreseeable future.

    License Revenues. License revenues increased 64% from $25.6 million for the
nine months ended September 30, 1998 to $42.1 million for the nine months ended
September 30, 1999, representing 76% and 71% of total revenues in the
respective periods. The increase in license revenues in absolute dollars was
primarily due to:

  .  increasing market awareness and acceptance of our product offerings;

  .  continued enhancement and increasing breadth of our product offerings;

  .  expansion of our sales and marketing organization; and

  .  sales to new industry segments.

    The decrease in license revenues as a percentage of total revenues was
primarily a result of the increasing support revenue stream and increased
demand for consulting services.

    Services and Maintenance Revenues. Services and maintenance revenues
increased 106% from $8.3 million for the nine months ended September 30, 1998
to $17.1 million for the nine months ended September 30, 1999, representing 25%
and 29% of total revenues in the respective periods. Services and maintenance
revenues have continued to increase in absolute dollars and as a percentage of
total revenues as our installed customer base has grown and as these customers
continue to renew their maintenance agreements. In addition, our increasing
customer base has resulted in an acceleration of demand for consulting services
to assist these customers as they deploy our solutions. We continue to focus on
building our relationships with outside service providers to ensure that we
have adequate resources available to meet the demand of our customers.

  Cost of Revenues

    Cost of License Revenues. Cost of license revenues consists primarily of
costs associated with product media, documentation, packaging and royalties to
third-party software vendors. Cost of license revenues increased from $1.3
million for the nine months ended September 30, 1998 to $1.4 million for the
nine months ended September 30, 1999, representing 4% and 2% of total revenues
for the respective periods. While the cost of license revenues was relatively
flat for the first nine months of 1999 compared to the first nine months of
1998, the decrease in cost of license revenues as a percentage of total
revenues for the nine months ended September 30, 1999 was primarily the result
of a shift in the mix of third-party software vendor products sold in the first
three quarters of 1999 compared to the same period in 1998. The mix of third-
party products may vary from period to period and our gross margins and,
consequently, our results of operations could be adversely affected.

    Cost of Services and Maintenance Revenues. Cost of services and maintenance
revenues consists primarily of personnel costs associated with customer
support, training and consulting services, as well as amounts paid to third-
party consulting firms for those services. Cost of services and maintenance
revenues increased 83% from $5.2 million for the nine months ended September
30, 1998 to $9.5 million for the nine months ended September 30, 1999,
representing 15% and 16% of total revenues for the respective periods. The
increase in costs in absolute dollars and as a percentage of total revenues
during the nine months ended September 30, 1999 reflected the increased costs
associated with the increased levels of services and maintenance revenues
experienced during the period.

                                       20
<PAGE>

    The gross margin with respect to services and maintenance revenues was 38%
and 45% for the nine months ended September 30, 1998 and 1999, respectively.
This increase in the services and maintenance margin reflected the shift in the
mix of services revenue toward higher-margin maintenance revenues. In addition,
the services personnel hired in 1998 were achieving higher productivity levels.

  Operating Expenses

    Sales and Marketing. Sales and marketing expenses increased from $18.3
million for the nine months ended September 30, 1998 to $28.9 million for the
comparable period in 1999. Sales and marketing expenses represented 54% of
total revenues for the nine months ended September 30, 1998, compared to 49%
for the comparable period in 1999. The increase in absolute dollars was
primarily the result of costs associated with the expansion of our sales and
marketing organization, both domestically and internationally, as well as
significant investments in marketing during the first three quarters of 1999 as
we launched a number of new products and marketing programs. We have continued
our strategy of (a) investing in hiring and training our direct sales
organization in anticipation of future market growth, and (b) investing in
marketing efforts in support of new product launches. Failure of these
investments to generate future revenues could have a significant adverse effect
on our operations. The decrease as a percentage of total revenues reflects the
higher revenue base as well as improvements achieved in productivity of sales
and marketing personnel and efficiencies gained in the related processes.

    Research and Development. Research and development expenses increased from
$9.0 million for the nine months ended September 30, 1998 to $12.1 million for
the comparable period in 1999. Research and development expenses represented
27% of total revenues for the nine months ended September 30, 1998, compared to
21% for the comparable period in 1999. The increased investment in research and
development expenses in absolute dollars reflects expenses related to increased
staffing of software developers. These employees were added primarily in the
second half of 1998 in connection with the continuing expansion and enhancement
of our product offerings and our commitment to quality assurance and testing,
and as a result of our acquisition of r3 Security Engineering AG in June 1998.
The investment in research and development as a percentage of total revenues
decreased for the nine months ended September 30, 1999 compared to the same
period in 1998, as a result of growth of revenues outpacing our expansion of
the development team in 1999. However, we believe that we must continue to
invest in research and development in order to maintain our technological
leadership position and, thus, expect research and development expenses to
continue to increase in absolute dollars as we hire additional experienced
security experts and software engineers.

    In accordance with Statement of Financial Accounting Standards No. 86,
"Accounting for the Costs of Computer Software to Be Sold, Leased or Otherwise
Marketed", we have evaluated the establishment of technological feasibility of
our various products during the development phase. The time period during which
costs could be capitalized from the point of reaching technological
feasibility, which has been defined as development of a beta model, until the
time of general product release is very short and, consequently, the amounts
that could be capitalized are not material to our financial position or results
of operations. Therefore, we charged all product development expenses to
operations in the period incurred.

    General and Administrative. General and administrative expenses increased
from $3.6 million for the nine months ended September 30, 1998 to $5.4 million
for the comparable period in 1999. General and administrative expenses
represented 11% of total revenues for the nine months ended September 30, 1998,
compared to 9% for the comparable period in 1999. The increase in general and
administrative expenses in absolute dollars reflected our continued investment
in

                                       21
<PAGE>

increased staffing and related expenses for the enhancement of the
infrastructure necessary to support our growing business, including improved
management information systems and the increased utilization of outside
professional service firms. The decrease as a percentage of total revenues
reflected efficiencies gained throughout our administrative processes as we
have grown as a company.

    Acquired In-process Research and Development and Goodwill Amortization. On
June 8, 1998, we completed the acquisition of r3, a company based in Zurich,
Switzerland, which provides consulting, applied research and product
development services related to commercial security and encryption solutions.
In connection with the acquisition in 1998, an appraisal was done of the
intangible assets, resulting in $20.2 million of the purchase price being
allocated to in-process research and development that had not yet reached
technological feasibility and had no alternative future use. This in-process
research and development was expensed in the nine months ended September 30,
1998. We recorded $534,000 of amortization with respect to the goodwill that
arose as a result of this acquisition in the nine months ended September 30,
1999, compared to $178,000 for the nine months ended September 30, 1998.

  Interest Income

    Interest income increased from $734,000 for the nine months ended September
30, 1998 to $2.7 million for the comparable period in 1999. This increase
reflects the investment income earned on the net proceeds of our initial public
offering in August 1998 and on cash provided by operations in 1999.

  Provision for Income Taxes

    We recorded an income tax provision of $927,000 for the nine months ended
September 30, 1999 compared with an income tax benefit of $160,000 recognized
for the nine months ended September 30, 1998. We account for income taxes in
accordance with Statement of Financial Accounting Standards No. 109.
Accordingly, the effective income tax rates differed from statutory rates due
to an adjustment to the valuation allowance for net operating loss
carryforwards from prior periods in the first three quarters of 1999, which
resulted in a tax provision of $927,000 for the nine months ended September 30,
1999. For the nine months ended September 30, 1998, the tax benefit of $160,000
arose primarily from Canadian research and development tax credits.

Years Ended December 31, 1996, 1997 and 1998

  Revenues

    Total Revenues. Total revenues increased 95% from $12.8 million in 1996 to
$25.0 million in 1997 and increased 96% to $49.0 million in 1998.
Geographically, revenues derived from sales outside North America accounted for
4%, 5% and 23% of total revenues for the years ended December 31, 1996, 1997
and 1998, respectively. We invested significantly in expanding our
international operations in 1998 through the acquisition of r3, the formation
of Entrust Japan, and the hiring of additional sales and marketing personnel.
In 1996, three customers accounted for an aggregate of 64% of revenues for that
year, and individually these customers accounted for 29%, 20% and 15% of
revenues, respectively. In 1997, three customers individually accounted for
19%, 12% and 11% of revenues, respectively. In 1998, no single customer
accounted for 10% or more of total revenues.

    License Revenues. License revenues increased 90% from $8.7 million in 1996
to $16.5 million in 1997 and increased 123% to $36.8 million in 1998,
representing 68%, 66% and 75% of total revenues in the respective years. The
increase in license revenues in absolute dollars was

                                       22
<PAGE>

primarily due to increasing market awareness and acceptance of our product
offerings, additional product development and increased sales and marketing
activities. The increase in license revenues as a percentage of total revenues
reflected our continued focus on the product side of the business and the
increased use of third-party consulting firms and systems integrators to
provide implementation services to our customers.

    Services and Maintenance Revenues. Services and maintenance revenues
increased 107% from $4.1 million in 1996 to $8.5 million in 1997 and increased
44% to $12.2 million in 1998, representing 32%, 34% and 25% of total revenues
in the respective periods. The increase in services and maintenance revenues
was primarily the result of an increase in demand for consulting services and
customer support, and increases in maintenance revenues from a larger installed
product base. The decrease in services and maintenance revenues as a percentage
of total revenues from 1997 to 1998 was largely due to our focus on building
the product side of the business and building successful partnering
relationships with third-party service providers to provide services to
customers.

  Cost of Revenues

    Cost of License Revenues. Cost of license revenues was $393,000 in 1996,
$502,000 in 1997, and $2.0 million in 1998, representing 3%, 2% and 4% of total
revenues for the respective years. The increase in cost of license revenues in
absolute dollars and as a percentage of revenues for 1998 and 1997 was
primarily a result of higher royalty fees paid to third-party software vendors.
We incorporated a higher level of third-party software in our products in 1998.

    Cost of Services and Maintenance Revenues. Cost of services and maintenance
revenues was $3.2 million in 1996, $4.4 million in 1997 and $7.5 million in
1998, representing 25%, 18% and 15% of total revenues for the respective years.
The increase in absolute dollars reflects the increased costs associated with
the higher levels of services and maintenance revenues during 1998 and 1997.
The decrease as a percentage of total revenues was primarily a result of
license revenues growing more rapidly than service and maintenance revenues.
The higher percentage of cost of services and maintenance revenues as a
percentage of total cost of revenues in 1997 and 1996 (79% in 1998 compared to
90% in 1997 and 89% in 1996) reflected the cost of hardware components related
to system integration arrangements during those years. We did not have a
significant hardware component of our system integration arrangements in 1998.

    Services and maintenance gross profit as a percentage of services and
maintenance revenues was 48% in 1997 and 38% for 1998. This decrease in the
services and maintenance margin reflected the investment made during 1998 in
expanding our customer support organization to support the growing customer
base and the impact on productivity related to the integration of the r3
consulting organization during the third and fourth quarters of 1998. Also,
investments were made in building our consulting organization in order to
prepare for expected future increases in demand for these services.

  Operating Expenses

    Sales and Marketing. Sales and marketing expenses increased from $3.9
million in 1996 to $11.2 million in 1997 and $26.8 million in 1998,
representing 30%, 45% and 55% of total revenues in the respective periods.
These increases in absolute dollars and as a percentage of total revenues were
primarily the result of costs associated with the expansion of our sales and
marketing organization to support increased revenue targets, both domestically
and internationally. We have continued our strategy of investing in hiring and
training our direct sales organization in anticipation of future market growth,
and investing in marketing efforts in support of new products launches.

                                       23
<PAGE>

Failure of these investments to generate future revenues could have a
significant adverse effect on our operations.

    Research and Development. Research and development expenses increased from
$2.9 million in 1996 to $5.7 million in 1997 and $12.8 million in 1998,
representing 22%, 23% and 26% of total revenues in the respective periods. The
increased investment in research and development expenses in absolute dollars
and as a percentage of total revenues in 1997 and 1998 primarily reflected
higher expenses related to increased staffing of software engineers and
contractors. These employees were added in connection with the continuing
expansion and enhancement of our product offerings and our commitment to
quality assurance and testing. In addition, the acquisition of r3 in June 1998
increased the size of our global research and development team.

    General and Administrative. General and administrative expenses increased
from $2.5 million in 1996 to $3.7 million in 1997 and $5.0 million in 1998,
representing 19%, 15% and 10% of total revenues in the respective periods. The
increase in general and administrative expenses in absolute dollars reflected
our continued investment in increased staffing and related expenses to enhance
the infrastructure required to support our growth, including investor relation
programs, improved management information systems and support and outside
professional service firms.

    Acquired In-process Research and Development and Goodwill Amortization. On
June 8, 1998, we completed the acquisition of r3, a company based in Zurich,
Switzerland that provides consulting, applied research and product development
services related to commercial security and encryption solutions. Pursuant to
the share purchase agreements dated May 30, 1998, entered into between us and
the shareholders of r3, we agreed to acquire all the outstanding shares of r3
in exchange for an aggregate of 1,167,288 shares of our common stock and cash
consideration of approximately $4.4 million. This acquisition was recorded
under the purchase method of accounting, and, therefore, the results of
operations of r3 and the fair value of the acquired assets and liabilities are
included in our financial statements beginning on the acquisition date. Upon
consummation of the acquisition, r3 became a wholly owned subsidiary of Entrust
Technologies Inc.

    In connection with the acquisition, we obtained an appraisal of the
intangible assets, which resulted in $20.2 million of the purchase price being
allocated to in-process research and development that had not yet reached
technological feasibility and had no alternative future use, which was expensed
in the year ended December 31, 1998. In addition, $356,000 of amortization had
been recorded with respect to the goodwill that arose as a result of this
acquisition in 1998.

  Interest Income

    Interest income increased to $723,000 in 1997 and $1.8 million in 1998,
representing 3% and 4% of total revenues in the respective periods. Interest
income was not significant in 1996. The increase in interest income in 1998
reflected the interest earned on the net proceeds of the initial public
offering in August 1998, while the increase in interest income in 1997
represented interest earned on the net proceeds of the private placement of
shares in January 1997.

  Provision for Income Taxes

    We recorded income tax benefits of $331,000, $281,000 and $160,000 in 1996,
1997 and 1998, respectively. Income taxes are accounted for in accordance with
Statement of Accounting Standards No. 109. The effective income tax rates
differed from the statutory rates primarily due to the impact of the Canadian
research and development tax credits claimed.

Quarterly Results of Operations

    Our quarterly operating results have varied substantially in the past and
are likely to vary substantially from quarter to quarter in the future due to a
variety of factors. In particular, our period-to-period operating results are
significantly dependent upon the completion date of large license agreements.
In this regard, the purchase of our products often requires a significant
capital investment which customers may view as a discretionary cost and,
therefore, a purchase that can be deferred or canceled due to budgetary or
other business reasons. Estimating future revenues is also difficult because we
ship our products soon after an order is received and, therefore, we do not
have a significant backlog. Thus, quarterly license revenues are heavily
dependent upon orders received and shipped within the same quarter. Moreover,
we have generally recorded a significant portion of our total quarterly
revenues in the third month of a quarter, with a concentration of these
revenues in the last half of that third month. This concentration of revenues
is influenced by customer tendencies to make significant capital expenditures
at the end of a fiscal quarter. We expect these revenue patterns to continue
for the foreseeable future. In addition, quarterly license revenues are
dependent on the timing of revenue recognition, which can be affected by many
factors, including the timing of customer installations and acceptance. In this
regard, we have from time to time experienced delays in recognizing revenues
with respect to certain orders. In any period a significant portion of our
revenue may be derived from large sales to a limited number of customers.
Despite the uncertainties in its revenue patterns, our operating expenses are
based upon anticipated revenue levels and such expenses are incurred on an
approximately ratable basis throughout the quarter. As a result, if expected
revenues are delayed or otherwise not realized in a quarter for any reason, our
business, operating results and financial condition would be adversely affected
in a significant way.

    The following tables set forth certain unaudited consolidated quarterly
statement of operations data for the eight quarters ended December 31, 1999, as
well as such data expressed as a percentage of our total revenues for the
periods indicated. These data have been derived from unaudited consolidated
financial statements that, in our opinion, include all adjustments, consisting
only of normal recurring adjustments, necessary for a fair presentation of such
information when read in conjunction with our consolidated financial statements
and related notes appearing elsewhere in this prospectus. The operating results
for any quarter are not necessarily indicative of results for any future
period.

*Not meaningful

    On January 18, 2000, we announced our results for the fourth quarter and
twelve months ended December 31, 1999.

    Revenues for the fourth quarter of 1999 increased to $26.0 million from
$15.0 million for the fourth quarter of 1998, an overall increase of 73%.
License revenues of $19.4 million in the fourth quarter of 1999 increased by
75% from $11.1 million during the comparable period in 1998. Services and
maintenance revenues in the fourth quarter of 1999 increased to $6.6 million
from $3.9 million for the comparable period in 1998, an increase of 69%. Net
income for the fourth quarter of 1999 was $2.7 million, representing $0.05 per
diluted share. The $0.05 per share compares to a net loss of $(805,000),
representing a net loss of $(0.02) per basic share in the fourth quarter of
1998.

    Total 1999 revenues of $85.2 million increased by 74% from $49.0 million in
1998. License revenues increased by 67% to $61.5 million in 1999, compared with
$36.8 million for 1998. Services and maintenance revenues in 1999 increased by
94% to $23.7 million, compared with $12.2 million for 1998. Net income of $5.9
million for 1999 generated $0.11 per diluted share, compared to a net loss of
$(3.6 million), or $(0.10) per basic share, for 1998, which excludes acquired
in-process research and development write-offs. Including the $20.2 million of
acquired in-process research and development write-offs, the 1998 net loss
increased to $(23.8 million), resulting in a net loss of $(0.68) per basic
share. In 1999, revenues from our three largest customers totaled 31% of
revenues, with the largest customer accounting for 23% of revenues.

Liquidity and Capital Resources

    We generated cash of $4.2 million from operating activities during the nine
months ended September 30, 1999. This cash inflow was primarily a result of an
increase in accrued liabilities and deferred income and the net income achieved
over the period. These inflows were partially offset by cash outflows relating
to an increase in accounts receivable, prepaid expenses, and a decrease in
accounts payable. Our average days sales outstanding for the quarter ended
September 30, 1999 was 72 days, which represents an increase over the 58 days
that we reported for the second quarter, but a reduction over the 84 days we
reported in the three quarters previous to that. The overall decrease in days
sales outstanding from the first quarter of 1999 reflects the improved
collection efforts over the quarters and the quality of our relationships with
our customers. For purposes of calculating average days sales outstanding, we
divide ending accounts receivable by the current quarter's revenues and
multiply this amount by 90 days. The level of accounts receivable at each
quarter end will be affected by the concentration of revenues in the final
weeks of each quarter and may be negatively affected by expanded international
revenues in relation to total revenues as licenses to international customers
often have longer payment terms.

    During the nine months ended September 30, 1999, cash from investing
activities of $5.5 million was provided by the reduction of our short-term
investments by $10.2 million, net of $87.6 million of short-term investment
purchases, offset by investments of $3.1 million in property and equipment and
$1.5 million in goodwill and other long-term assets. The property and equipment
investments primarily took the form of computer hardware and leasehold
improvements to support our growing organization.

    Cash provided by financing activities for the nine months ended September
30, 1999 was $7.0 million, primarily due to the exercise of employee stock
options and the sale of shares under our employee stock purchase plan.

    As of September 30, 1999, our cash and short-term investments in the amount
of $85.3 million comprised our principal sources of liquidity. It is our belief
that cash flows from operations, the net proceeds from this offering and
existing cash and cash equivalents and short-term investments will suffice to
meet our needs for at least the next twelve months.

Year 2000 Impact

    We have not experienced any problems with our computer systems relating to
such systems being unable to recognize appropriate dates related to the year
2000. We are also not aware of any material problems with our clients or
vendors. Accordingly, we do not anticipate incurring material expenses or
experiencing any material operational disruptions as a result of any Year 2000
issues.

Quantitative and Qualitative Disclosures about Market Risk

  Risk Associated with Interest Rates

    Our investment policy states that we will invest our cash reserves,
including cash, cash equivalents and marketable investments, in investments
that are designed to preserve principal, maintain liquidity and maximize
return. We actively manage our investments in accordance with these objectives.
Some of these investments are subject to market risk, whereby a change in
market interest rates will cause the principal amount of the underlying
investment to fluctuate. Therefore, a depreciation in principal value of an
investment is possible in situations where the investment is made at a fixed
interest rate and the market interest rate then subsequently increases. We try
to manage this risk by maintaining our cash, cash equivalents and marketable
investments with high quality financial institutions and investment managers.
We also restrict the investments to primarily securities with short-term
maturities, such that, at September 30, 1999, the majority of our marketable
investments had maturities of less than six months from that date. As a result,
we believe that our exposure to market risk related to interest rates is
minimal.

    The following table presents the cash, cash equivalents and marketable
investments that we held at December 31, 1998 and September 30, 1999, that
would have been subject to market risk, and the related ranges of maturities as
of that date:

  Risk Associated with Exchange Rates
    We are subject to foreign exchange risk as a result of exposures to changes
in currency exchange rates, specifically between the United States and Canada,
the United Kingdom, Germany and Switzerland. However, this exposure is
considered to be minimal due to the fact that the United Kingdom, German and
Swiss operations are not significant, and the Canadian operations are naturally
hedged against exchange rate fluctuations since both revenues and expenses are
denominated in Canadian dollars. Therefore, an unfavorable change in the
exchange rate for the Canadian subsidiary would result in lower revenues when
translated into U.S. dollars, but the expenses would be lowered in a
corresponding fashion.

    As a result, we do not engage in formal hedging activities, but we do
periodically review the potential impact of this risk to ensure that the risk
of significant potential losses remains minimal.

billion in 2003. Since 1994, we have provided our PKI solution primarily to
global enterprises and government entities, including Citibank, FedEx, MCI
Worldcom, NASA, the United Kingdom Post Office and the Canadian Department of
National Defense. To date, over four million users worldwide have been licensed
to use Entrust products.

    Our PKI solution is particularly relevant to organizations in the growing
business-to-business, or B2B, electronic commerce market. We offer B2B
organizations a comprehensive security solution that includes the robust
functionality required to support their increasingly advanced and high-value

positioned to capitalize on our PKI market leadership to address B2B and other
important markets, such as the business-to-consumer, or B2C, market. We are
also actively developing additional functionality to address emerging
opportunities, such as the growing need to secure e-business transactions
conducted over wireless networks.

    We are headquartered in Plano, Texas with offices in Canada, the United
Kingdom, Switzerland, Germany and Japan, as well as additional offices in the
United States.

Industry Background

    The widespread adoption in recent years of public and private networks has
revolutionized the manner in which organizations communicate and conduct
business. These advanced networks provide an attractive medium for
communications and commerce because of their global reach, accessibility, use
of open standards and ability to permit interactions on a real-time basis.
Proliferation of these networks has facilitated the storage, analysis and
communication of critical information within and between organizations. At the
same time, they have afforded businesses a user-friendly, low-cost way to
conduct a wide variety of commercial functions electronically. Today,
organizations are increasingly utilizing these networks to access new markets,
improve customer service and streamline business processes. These types of
electronic interactions can occur with a variety of audiences, each of which
may have different business requirements for information security because of
the nature and content of their communications and transactions. Electronic
interactions can be divided into two market-based categories: business-to-
business and business-to-consumer.

  .  Business-to-business transactions and communications occur between
     businesses and other organizations, and internally within these
     entities. Forrester Research, Inc. estimates that the market for B2B e-
     commerce will be $1.3 trillion by the year 2003. B2B transactions
     generally require pre-existing or centrally managed relationships
     between participants. Goods and services transacted through B2B
     relationships are primarily paid for by means other than credit cards
     and, therefore, do not receive the fraud protection provided to
     consumers by credit card companies. B2B communications can also be
     purely informational where the information being sent between parties
     is often highly sensitive. For example, product research communications
     between a pharmaceutical company and a collaborating university contain
     extremely valuable intellectual property or confidential information
     that needs to be properly protected. Business processes involved in B2B
     transactions and communications are

                                       30

   frequently complex, resulting in a need for sophisticated networking and
   software solutions. The B2B market typically requires supply-chain
   management software, procurement and payment systems, virtual private
   networking and remote access solutions, electronic mail systems,
   electronic forms software, sophisticated Web-based solutions, database
   systems and human resources applications.

  .  Business-to-consumer transactions and communications are generally
     interactions between a selling organization and the general public.
     Forrester Research, Inc. estimates that the market for online consumer
     transactions will be $108 billion by the year 2003. B2C interactions
     are typically less complex than B2B interactions, often do not require
     a pre-existing relationship between buyer and seller and generally have
     fewer information security requirements than their B2B counterparts.
     Although many B2C interactions are currently executed over the Web
     using out-of-the-box Web browser and server software security
     capabilities, we anticipate that B2C participants will require more
     complete security solutions.

  Need For Secure Transactions and Communications

    The very openness and accessibility that have stimulated the adoption and
growth of public and private networks create threats to the privacy and
integrity of transactions and communications that are transmitted across or
stored on them. Key information security concerns relating to electronic
interactions include the risk of theft, alteration, interception or
dissemination of confidential data, fraud, loss of reputation and economic
loss. Threats to information security arise both from external sources such as
competitors and computer hackers, as well as internal sources, such as curious
or disgruntled employees and contractors. These risks have driven the demand
for effective and robust network and information security products.

    The security risks associated with communications and commerce over public
and private networks have accentuated the need for information security
solutions that address six critical network security needs:

    Access Control. Only authorized users should access, view or modify certain
data.

    Confidentiality. Data in transit over the network or in storage should not
be disclosed to unauthorized persons.

    Integrity. Data should not be altered or compromised by unauthorized
manipulation.

    Authentication. The identities of the parties involved in communications
and transactions should be verified.

    Authorization. Individuals should only be able to execute transactions or
perform operations for which they have permission.

    Nonrepudiation. The parties involved in an electronic exchange should not
be able to deny or repudiate the exchange.

    A wide range of products and services has been introduced to address one or
more of these six critical network security needs. For example, access control
is provided by products such as firewalls and password tokens, which limit
network access only to users having recognized addresses or entering recognized
passwords, but are limited in their flexibility and do not address such
requirements as confidentiality, integrity, authorization and nonrepudiation.
Encryption devices and programs provide confidentiality, but are device-
dependent and do not address issues of access control, integrity,
authentication, authorization and nonrepudiation. The lack of flexibility and
scalability inherent in these solutions has led to the development of public-
key encryption and digital certification systems combined in a public-key
infrastructure, which can address all six critical network security needs.

  Public-Key Security

    A public-key infrastructure uses encryption algorithms in combination with
authentication and verification technology offered by digital certificates to
provide users with a secure and reliable means of communicating and effecting
transactions over public and private networks.

    Public-Key Encryption. Digital messages are encrypted and decrypted using a
cipher or key. Public-key encryption systems assign each user a pair of linked
keys: a "public" key, which the user provides to others, and a "private" key,
which the user keeps secret. A user wishing to send a secure transmission
encrypts the transmission using the recipient's public key. To decode the
transmission, the recipient uses a private key that is uniquely able to decode
messages encoded with his or her corresponding public key. Thus, the successful
exchange of encrypted messages using a public key system requires that message
senders have the public keys for all recipients to whom they desire to send
messages, and that the recipients decode messages with their own private keys.
Public-key encryption provides a high level of data security, and thus
addresses an enterprise's need for confidentiality of electronic transmissions.
However, because encryption alone does not give the recipient of a message any
information about the sender or ensure that a message is not altered en route,
the requirements for access control, integrity, authentication, authorization
and nonrepudiation are not satisfied.

    Digital Certification. In addition to providing confidentiality, digital
certification systems use public and private keys to create digital signatures.
These signatures are encoded using the sender's private key. Upon receipt of
the message, the recipient obtains a copy of the sender's public key, which
verifies that the message originated from the expected sender. Public keys are
maintained in digital certificates issued by a Certification Authority, or CA.
Digital certificates securely bind the owner's identity to his public key.
Digital certificates thus function as electronic passports that not only
authenticate their owners' identities and verify their owners' membership in
certain organizations, but also establish their owners' authority to engage in
a given transaction. Digital signature and certification technology also
ensures the integrity of a message by enclosing an encrypted summary or "hash"
of the message with the sender's digital signature. When the signature and hash
are decrypted using the sender's public key, the system can automatically
detect whether the message was altered since it was signed.

    The security benefits of digital certification have led to increasing
market demand particularly in markets where information security is critical,
such as government, finance, health care and telecommunications. This
increasing demand has given rise to numerous products and services that issue
digital certificates or that are able to work with digital certificates.
However, the mere issuance of digital certificates does not ensure that a
user's access is properly monitored, that privileges associated with access are
accurately and currently defined, or that the certificates in question have not
been updated, withdrawn or replaced. Indeed, the proliferation of users and
certificates greatly complicates management of these types of issues, which are
critical to maintaining an effective security environment across and between
organizations.

  Need For a Comprehensive, End-to-End Public-Key Infrastructure

    To address the management and business issues associated with use of
public-key encryption and certificates, organizations, particularly those in
the B2B market, must have a robust public-key infrastructure that supplements
certificate issuance functions with full life cycle management of public and
private keys, including issuance, authentication, storage, retrieval, backup,
recovery, updating and revocation. In addition, these functions must operate in
an easy-to-use, cost-effective manner.

    Moreover, unless digital certificates and private keys can be easily
utilized on a consistent and reliable basis across multiple applications,
organizations will face the challenge and cost of maintaining a separate
security infrastructure for each application. Maintaining these different
security infrastructures could result in separate keys and certificates for
each user for different applications, multiple passwords and inconsistent or
incomplete security implementations. Such a disconnected, inconsistent set of
products would be costly to operate and difficult to use. Furthermore, any PKI
must be able to support an organization's security requirements as the
enterprise grows, business functions are altered, and underlying information
technologies evolve. To be effective, a public-key infrastructure must be able
to accommodate a large number of users and integrate diverse computing
resources into a cohesive, reliable and secure computing environment that meets
the six critical network security needs.

    Achieving these goals requires a highly functional and flexible public-key
infrastructure that enables secure communications between and within
organizations. The need for comprehensive, end-to-end public-key infrastructure
solutions is particularly apparent for B2B transactions and communications, the
majority of which have information security requirements that are met only by
complete, end-to-end solutions that are cost-effective to operate and easy to
use.

The Entrust Solution

    We are the leading global provider of comprehensive, end-to-end public-key
infrastructure solutions, encompassing both products and services, that enable
e-businesses and other organizations to effectively manage secure transactions
and communications across a wide range of applications. Our PKI solution
addresses the six critical network security needs and allows for consistent
security policy management across and between organizations, and enables any
organization to establish its own flexible, highly reliable PKI. We also offer
users encryption functionality and full digital signature and certification
management in an easy-to-use, integrated and automated solution. Among the
benefits offered by our PKI solution are:

    Comprehensive, End-to-End Functionality. We believe that we are the only
provider of a comprehensive, end-to-end PKI solution offering the functionality
necessary for the full life-cycle management of keys and digital certificates,
including:

  .  certificate issuance;

  .  certificate authentication;

  .  key storage and backup;

<PAGE>

    Multiple Certificate Types. Our products and services support multiple
certificate types and configurations, including:

  .  Multi-application certificates that can be used across multiple
     applications. A user's single set of multi-application certificates can
     be accessed via our single sign-on solution and used across a wide
     variety of applications, including e-mail, e-forms, supply-chain
     management, payments and procurement, desktop encryption and remote
     access. Multi-application certificates enable ease-of-use because users
     only have one password to access numerous applications within an
     organization. One set of multi-application certificates per user also
     reduces operating costs because a single, comprehensive infrastructure
     supports a wide variety of applications. Since multi-application
     certificates are particularly valuable in the B2B marketplace, we
     believe that our solution is well-positioned to take advantage of the
     increasing number of e-business transactions and communications in that
     market.

  .  Single-application certificates that allow enterprises to restrict use
     of the certificates by a particular user to one application. Customers
     can easily convert single-application certificates to multi-application
     certificates by extending their license with us. There are no
     technology changes required to convert single-application certificates
     to multi-application certificates.

  .  Web certificates, including certificates for Web servers that are
     frequently used to secure B2C credit-card transactions.

  .  Virtual private networking, or VPN, certificates for establishing
     secure, real-time communications sessions over networks.

  .  Wireless application protocol, or WAP, server certificates for
     establishing secure, real-time communication sessions with wireless
     devices such as cellular telephones.

    Our support of multiple certificate types offers flexibility and choice to
customers who can select the types of certificates and solutions that best meet
their current business and information security requirements and provides a
system that is easily adaptable to meet future security requirements.

    Open, Versatile Platform. Our PKI operates across a wide range of computing
platforms, including:

  .  Windows NT and UNIX servers;

  .  UNIX, Macintosh, Windows (95, 98, NT, 2000) and JAVA clients;

  .  applications, including e-mail, supply-chain management, payments and
     procurement, desktop encryption, secure file erasure, electronic forms
     and remote access;

  .  wireless devices such as cellular telephones and pagers;

  .  biometric devices, such as fingerprint readers, and smart cards;

  .  network infrastructure, including firewalls, network operating systems
     and directories; and

  .  open industry standards, such as the lightweight directory access
     protocol and well-known encryption algorithms, such as RSA, elliptic-
     curve, DES and Triple-DES.

    Because many organizations operate numerous platforms for critical business
systems, support for a wide variety of operating systems, devices, applications
and open standards is essential to address B2B information security
requirements. We also believe that support for these platforms makes us
attractive to partners whose products and services work on multiple platforms.

                                       34

    Highly-Scalable Architecture. Our products employ a distributed computing
architecture and directory management techniques that make them highly
scalable. One of our customers has used our products to support over 100,000
users, and we believe that our PKI solution can be configured to handle
millions of users.

    Ease Of Use. Our products automatically and transparently enable complex
certification and key management functions without requiring any action by the
user. Users can access most functions via a single user login and simple point
and click graphical interfaces. We believe that our PKI solution enables users
to execute complex information security functions without needing significant
training, and in many cases no training at all is required. Furthermore, we
believe that the ease of use of our PKI solution is a significant benefit to
customers and differentiates our solution from those of other PKI vendors.

    Reduced Cost Of Ownership. Our PKI solution enables organizations to
significantly reduce overall costs for addressing information security for the
following types of reasons:

  .  comprehensive and automated functionality reduces duplication of
     personnel;

  .  its ease of use simplifies or eliminates the need for training; and

  .  its ability to interact with a wide variety of platforms and
     applications avoids the need to purchase multiple security systems.

    Full Range of Support Services. We supply a comprehensive set of support
services to organizations using our PKI solution. These services include:

  .  management of outsourced PKI operation and maintenance provided in
     conjunction with partners;

  .  software upgrades and maintenance;

  .  telephone support; and

  .  installation and project management services.

    Flexibility. Our PKI solution supports a wide variety of features and
options, allowing customers to easily select the types of functionality they
desire. This flexibility allows customers to allocate resources and tailor
capital expenditures to meet their specific business and information security
requirements. For example, our solution enables customers to begin with a less
complex system and cost-effectively add advanced features as their security
requirements change. In addition, the versatility of our solution allows
customers to choose whether they wish to operate the PKI themselves or
outsource the back-end management of the PKI to us or other third parties. At
the same time, customers are able to change these types of decisions in the
future as their business needs change, and still maintain the value of their
investments in our solution.

Strategy

    Our objective is to maintain and enhance our position as the leading global
provider of comprehensive, end-to-end PKI products and services that enable
organizations to effectively manage secure transactions and communications
across a wide range of applications. Key elements of our strategy include the
following:

    Capitalize on B2B Market Opportunities. We are focused on developing,
marketing and selling products and services that enable secure B2B transactions
and communications. We believe that our market leadership is founded on our
strength and capabilities in providing an end-to-end, comprehensive solution
required in the B2B market. Although we currently have numerous, large
customers in this market, we believe that the market is still in the early
stages of development and

                                       35
<PAGE>

provides substantial growth opportunities in the future. We are targeting our
sales and marketing activities at Global 2000 organizations and large
government organizations having significant requirements for comprehensive PKI
solutions and the resources to deploy them broadly. In particular, we are
focusing our efforts in the finance, government, health care,
telecommunications and large manufacturing sectors. Organizations in these
markets frequently have thousands of customers, partners, subscribers and
service recipients who will, directly or indirectly, benefit from secure
transactions and communications enabled by our PKI solution.

    Pursue Wireless Opportunities. We have developed, and will continue to
develop, PKI products for wireless devices. We intend to aggressively pursue
further extensions of our solution into the wireless market, including
solutions for cellular telephones, pagers and other wireless-enabled devices
such as personal digital assistants, or PDAs. We believe that these devices
will be increasingly used in B2B and B2C transactions and communications.

    Maintain Product Leadership and Increase Brand Recognition. Our PKI
solution has been deployed commercially through multiple versions for over five
years. Our technological leadership is attributable in large part to our
research and development team, which includes researchers with international
reputations in their fields. We intend to maintain and enhance our
technological leadership in the e-business security market by continuing to
invest in product research and development, to extend the functionality and
interoperability of our products, and to participate actively in industry
standards-setting organizations. We believe that our current set of products
and technologies provides an extensive, versatile foundation that can be
efficiently extended or modified to address new opportunities as they arise in
the market. We further intend to capitalize on our product leadership by
increasing brand awareness. Our goal is to equate our brand name with trusted
e-business security. We undertake a variety of activities to promote the
recognition of our brand identity and products, including the promotion and
sponsorship of industry groups and conferences such as the Entrust
SecureSummit.

    Expand and Leverage Strategic Relationships. To encourage widespread
acceptance of our PKI solution, we have established an Entrust Partner Program
which currently includes:

  .  Value-added resellers and original equipment manufacturer partners,
     such as Compaq, Check Point Software, Newbridge Networks and IBM, which
     resell our products with their hardware and networking solutions;

  .  Consultant and system integration partners, such as
     PricewaterhouseCoopers, Ernst & Young and KPMG, which recommend and
     implement our Entrust PKI solution as part of their overall service
     offerings;

  .  Application development partners, which have introduced more than 75
     off-the-shelf, certified Entrust-Ready products and applications,
     including solutions for SAP R/3, PeopleSoft, Documentum, Sybase, Nortel
     Networks, Lucent, Adobe, Novell GroupWise, Axent, Jetform and Shana. We
     have also announced expected solutions forthcoming from major vendors
     such as Intel and Lotus Development;

  .  Interoperability partners such as Cisco, Netscape, Microsoft and
     Network Associates, which offer products that can interoperate with and
     utilize the security features of our PKI solution;

  .  Managed services partners such as First Data Corporation and EDS, which
     offer or plan to offer outsourcing services for our customers; and

  .  Wireless partners such as Nokia and Research In Motion, or RIM, which
     offer interoperable security solutions with their devices.

    We intend to continue to invest in and enhance the Entrust Partner Program,
which provides services and products to partners, both to offer complete e-
business security solutions to our customers and to broaden adoption of our PKI

                                       36
<PAGE>

    Further Penetrate B2C Market. We intend to continue to expand our product
offerings and customer base by developing, marketing and selling products and
services for secure B2C interactions. In late May 1999, we founded a
certification authority services business, called Entrust.net, which currently
provides certificates for Web servers and wireless servers. From July through
December 1999, Entrust.net sold approximately 4,300 Web server certificates. We
believe that we obtained approximately 5% of the worldwide market for these
certificates in our first two full quarters of operation. Providing B2C
solutions allows us to add significant value to our B2B customers who often
prefer a single provider for all of their PKI solutions. Another element of our
B2C strategy includes embedding our certification authority in popular
applications, such as Microsoft's and Netscape's browsers and Microsoft's
Windows 2000 operating system.

    Leverage Global Presence. We intend to leverage and expand our global
operations. We had 53 employees based in Europe as of December 31, 1999. With
our acquisition of r3 Security Engineering in June 1998, we obtained
substantial European research and development expertise for the development of
our PKI solution targeted at the European market. Our distribution partners in
Europe and Japan provide further coverage to address Global 2000 organizations
in target markets.

Products and Product Development

    Our PKI solution provides an integrated, open and scalable security
framework that addresses e-business security needs across multiple platforms
and applications. It also includes robust features, such as support of multi-
application certificates, that make it well-suited for high-value, business-to-
business applications. Our solution includes:

  .  a PKI infrastructure, which provides the requisite networking and
     security features to enable secure transactions and communications;

  .  desktop applications that transparently integrate features of our PKI
     into common third-party desktop applications to address business-to-
     business and business-to-consumer transactions; and

  .  application developer toolkits that allow application developers to
     quickly and safely develop Entrust-Ready applications because the
     toolkits do not require developers to understand the complexities of
     information security.

  PKI Infrastructure

    Our PKI infrastructure comprises software that manages and administers life
cycles of keys and digital certificates throughout an organization and across
multiple applications. The management of keys and digital certificates is
essential to maintain security, ease of use and low-operating costs in a PKI
solution. Critical elements of a PKI system, such as routinely updating keys
prior to expiration and maintaining copies of historical keys to ensure data
"locked" by these expired keys will not be lost, is all handled automatically
by our PKI solution. These and other features are managed transparently to
maintain a system that is easy to use, secure and low-cost to operate.

    The PKI infrastructure also includes a directory compliant with the
lightweight directory access protocol, or LDAP, for the storage and retrieval
of certificates and software that enables applications and users to access the
functionality provided by the PKI. The infrastructure is configurable to
support the generation of certificates for virtual private network technologies
and Web browsers and servers. The infrastructure also supports multiple
hardware devices, such as smart cards, PC cards, biometric devices and third-
party key storage systems. Finally, the infrastructure provides a secure
timestamping capability that is valuable in business-to-business transactions
and communications where the tracking of time is an important element of the
interaction.

                                       37
<PAGE>

    Our PKI infrastructure is designed with an open and flexible software
architecture that operates on a wide range of client/server platforms,
including:

  .  Windows NT, HP-UX and Solaris servers;

  .  Windows (95, 98, NT, 2000), HP-UX, Solaris, AIX, JAVA and Macintosh
     clients; and

  .  wireless devices, including cellular telephones and pagers.

    Our software supports a wide variety of encryption algorithms, including
RSA, as well as symmetric and hashing algorithms, allowing customers to select
those algorithms best suited for their requirements. The system uses the LDAP
standard to interoperate with most major directory systems, allowing customers
to utilize existing directory systems and facilitating access to other
directories as required. The system architecture enables us to add
functionality as customer needs evolve and grow and allows the infrastructure
to support the generation and maintenance of new certificate types easily,
responding to technology developments and market pressures. The system's
distributed computing architecture and directory management techniques also
enable the PKI to be scaled as an organization's security needs increase or as
users are added to existing infrastructures.

    We released the initial version of our PKI in 1994, with major upgrades in
1996, 1997, 1998 and 1999. Historically, the PKI infrastructure has generated a
major portion of our revenues. The following table lists the products that
constitute our core PKI solution, as well as a brief description of each
product.

  .  helping users recover lost keys and forgotten passwords; and

  .  revoking users' certificates when necessary.

    Entrust/AutoRA. Entrust/AutoRA allows customers to securely automate
initial registration and administration of users. Automated registration is
particularly important for highly-scalable customer environments to ensure that
operating costs are minimized.

    Entrust/Roaming. Entrust/Roaming allows mobile users to securely access
their keys and certificates across multiple workstations without having to
manually transport their keys and certificates on a device such as a smart card
or floppy disk.

    Entrust/Timestamp. Entrust/Timestamp allows users to securely associate the
current date and time with an e-business transaction or communication.

    Entrust Electronic Identities. Our Electronic Identity is an individual
user's "account" or profile within the PKI. We offer Electronic Identities for
multi-application or single-application use, or for more limited Web or virtual
private networking use. Each multi- and single-application Electronic Identity
can support numerous key pairs and certificates over its lifetime. Multi-
application Electronic Identities may be used across multiple Entrust-Ready
applications whereas single-application Electronic Identities are licensed for
use with one application. Our multi- and single-application Electronic
Identities include software, known as Entrust/Entelligence and Entrust/Engine,
that enables users and applications to access essential functionality within
our PKI. A Web Electronic Identity enables a user to use certificates with
popular Web browsers and Web servers. VPN Electronic Identities enable
standards-compliant virtual private network technologies to establish secure
electronic communications over public networks like the Internet.

  Entrust Applications

    Our PKI infrastructure supports a wide variety of applications from
multiple vendors that enhance the flexibility and usefulness of our PKI. We
have also developed a number of applications in order to meet specific customer
demands and facilitate the implementation of our PKI solution. These products
both complement and interact with the PKI infrastructure to offer users
enhanced functionality and increased interoperability with third-party
applications, or they can operate as independent products, offering distinct
functionality.

  Application Developer Toolkits

    Our toolkits are a family of open, easy-to-integrate programming interfaces
that provide security services, including full key life cycle management, to a
broad range of applications. These toolkits operate across a variety of
operating systems and support multiple programming languages. Because key and
certificate management represents the most difficult aspect of adding security
to an application, we provide toolkits to enable application developers to make
their applications Entrust-Ready. The toolkits allow developers to rapidly make
their applications secure but do not require developers to understand the
complexities of information security. Our toolkits reduce the operating costs
of their applications because customers only have to operate a single PKI and
their Entrust-Ready applications operate in a consistent, cohesive manner.

  New Product Development

    We devote significant resources to the development of new and enhanced
product functionality to maintain our technology and product leadership. We
employ a number of different methods for identifying product extension
opportunities and new product candidates, including user group meetings and
direct feedback, an active program of partnership and cooperation with
companies developing complementary technologies, and continued participation
and leadership in industry standards-setting bodies such as the Internet
Engineering Task Force (IETF), the North American Clearinghouse Association
(NACHA), the American National Standards Institute (ANSI) and the PKI Forum.

    Some of our current and planned product development efforts include:

  . additional products and services to secure transactions and
    communications over wireless devices such as cellular telephones, pagers
    and PDAs;

  . attribute certificates for privilege management;

  . electronic notary products and services; and

  . monitoring and assessment systems.

                                       40
<PAGE>

    We are also continuing to increase the number of third-party applications
and services that our PKI solution can manage, including VPN devices and
routers and other popular user applications. Our scientists are also actively
engaged in the development and improvement of the advanced cryptographic
algorithms for use in our products.

Services and Support

  Professional Services

    We believe that a high level of service and support is critical to our
success, and that a close and active service and support relationship is
important to facilitate rapid implementation of our solution, assure customer
satisfaction and provide us with important information regarding evolving
customer requirements. Toward these ends, we have made a significant investment
in expanding our services and support organization, which, as of December 31,
1999, consisted of 97 employees. Our services personnel have a broad range of
experience in network security and include mathematicians, cryptographers and
system designers. Furthermore, we are supplementing our traditional services
and support revenue streams with additional service-based revenue streams, such
as the revenue we receive through Entrust.net.

    Our professional services organization provides consulting and systems
integration services to support customers in designing, implementing and
running our PKI solution. Activities of the professional services organization
are supplemented with a professional services partner program that includes
PricewaterhouseCoopers, Ernst & Young and KPMG. To facilitate the integration
of PKI management into the customer's business operations, we also offer our
Entrust InSource service, in which we provide on-site PKI management for
customers on a long-term basis, or while the customer implements and trains
personnel.

    Our support offerings also include:

  . direct telephone consulting support by experienced technical account
    representatives;

  . 24-hour pager access, e-mail and fax support;

  . Internet access to our knowledge repository; and

  . discussion group access.

Payment of an annual maintenance fee also entitles customers to receive
software enhancements to their licensed versions of our solution.

  Certification Authority Services

    In May 1999, we launched a certification authority services business called
Entrust.net. Entrust.net manages the issuance of multiple types of
certificates, including Web server certificates that are frequently used to
secure Web-based, B2C transactions. The list price for a one-year Web server
certificate is $299 and for a two-year certificate is $499. Entrust.net also
provides certificates to secure wireless transactions between cellular
telephones and WAP servers. The list price for a one-year WAP certificate is
$695 and for a two-year WAP certificate is $1,195.

    Entrust@YourService

    We recently announced Entrust@YourService, a managed services model for
delivering outsourced security solutions for B2B and B2C transactions and
communications. As part of the launch of Entrust@YourService, we entered into a
strategic alliance with Cash Tax, Inc., a subsidiary of First Data Corporation,
a large electronic commerce and payment services company. Through this
alliance, we plan to address the growing needs of customers that want to enable
e-business solutions but choose to outsource the ongoing operational tasks.
Entrust@YourService is designed to quickly and efficiently provide customers
with comprehensive, end-to-end security solutions while still allowing these
customers to retain control of the system implementation.

                                       41
<PAGE>

    The full range of solutions available to customers operating their own
PKI's are available to customers taking advantage of Entrust@YourService.
Moreover, because both the in-house and managed services model use the same
technology, customers have the flexibility to easily transition between the two
models to support their evolving business needs. We expect to make
Entrust@YourService commercially available during the first quarter of 2000.

Research and Development

    Our research and development efforts are focused on developing new
products, core technologies and enhancements to existing product lines to
maintain and extend our technology and product leadership position. We spent
approximately $5.7 million, $12.8 million and $16.6 million on research and
development in 1997, 1998 and 1999, respectively.

    As of December 31, 1999, our research and development staff consisted of
166 employees. With the addition of r3, we added significant research and
development capabilities in Europe and expanded our internationally-recognized
team of professional cryptographers.

    Our research and development staff is active in several prominent
standards-setting bodies, including IETF, ANSI, the Internet PKIX group and
ISO, and has contributed to a number of standards in the Internet and data
security areas. We believe that we are well situated to respond to changes in
relevant industry standards and to continue to participate in the development
of these standards as the requirements of enterprises and users become
increasingly complex.

Customers

    Our customers are generally domestic and foreign government entities and
Global 2000 companies, including financial, health care, telecommunications and
large manufacturing organizations. As of December 31, 1999, we had licensed our
software to more than 1,300 customers. The following is a representative list
of our current customers that have accounted for more than $200,000 of revenues
each:

  Banca Nazionale del         Industry Canada        Royal Canadian
  Lavoro                      Interpay               Mounted Police

                                                     Trade Office
                                                     U.S. Postal Service

    Historically, a limited number of customers have accounted for a
significant percentage of our revenues. In 1997, our three largest customers
accounted for 19%, 12% and 11% of our total revenues. In 1998, our three
largest customers accounted for an aggregate of 23% of total revenues, with no
individual customer accounting for more than 10% of revenues. In 1999, our
three largest customers accounted for an aggregate of 31% of revenues, with the
largest customer accounting for 23% of revenues. Although our largest customers
have varied from period to period, we anticipate that our results of operations
in any given period will continue to depend to a significant extent upon
revenues from a small number of customers.

Sales, Marketing and Business Development

    We offer our products and services through a multi-tiered approach
reflecting the characteristics and buying behavior of the markets we cover. As
of December 31, 1999, we had 212 employees in sales, marketing and business
development.

                                       42

  Direct Sales

    To address our target market of Global 2000 organizations, we sell our
products and services in North America, the United Kingdom and Germany
primarily through a direct sales force. We believe that direct coverage by our
sales force is necessary in light of the early stage of PKI adoption and the
sophisticated requirements of our targeted customer base, and that a direct
sales force gives us a competitive advantage in responding to customer needs as
they evolve. Our direct sales force is divided into five North American
regions, the United Kingdom and Germany. We assign teams within each region to
specific accounts as their exclusive responsibility. We have also focused our
sales efforts on key vertical markets that have a critical need for security
and understand the value it creates for their businesses. These markets include
government, finance, health care, telecommunications and large manufacturing.

    We also established a General Markets Sales Group responsible for
identifying and pursuing customer opportunities outside the defined
responsibilities of the regional sales teams. The direct sales organization is
also supplemented by targeted direct mail and telemarketing campaigns developed
by our marketing organization. Finally, the direct sales organization is
actively involved in selling all of our products and services, including those
available from Entrust.net.

  Indirect Sales

    To supplement our direct sales force, we have an Entrust Partner Program
involving a range of technology, marketing and sales relationships including:

  . VAR and OEM partners that focus on creating bundled solutions to permit
    customers to purchase total desktop applications incorporating our
    functionality. These partners include Compaq, Hewlett-Packard and IBM,
    which resell our products with their hardware and networking solutions,
    as well as Check Point Software and Newbridge Networks, which bundle our
    PKI solution with their own software products;

  . distributors and agents that promote and sell our products in defined
    geographic markets;

  . consultant and systems integration partners that recommend and implement
    Entrust-Ready security solutions as part of their overall service
    offerings to customers, thereby differentiating their offerings through
    the inclusion of PKI functionality. These partners include
    PricewaterhouseCoopers, Ernst & Young and KPMG; and

  . referral partners that refer their consulting and integration customers
    in designated markets to our PKI solution.

  Marketing

    To support our sales force, we have a marketing group whose goals are to
create a consistent, focused communication strategy that increases awareness of
our PKI solution and brand name, and to leverage that awareness in the
identification of new sales opportunities. The marketing group conducts
marketing programs that include direct mail, trade shows, annual seminar
series, executive breakfasts and ongoing customer communication programs. We
have organized a number of major trade shows, including the annual Entrust
SecureSummit to be held this year in Dallas, Texas in May. We also provide
frequent Web updates, search engine registration, online advertising and
product downloads.

  Business Development

    To identify and develop strategic relationships with targeted industry
partners more effectively, we have a business development organization of 17
persons as of December 31, 1999 that pursues

                                       43
<PAGE>

selected business development activities, including the administration and
promotion of our Entrust Partner Program. These activities permit us to
strengthen our relationships with existing strategic partners and identify and
encourage new providers of software, network, computing and communications
products to make their products Entrust-Ready. Our business development
personnel are divided into three distinct teams that focus on B2B, B2C and
general application partners.

Competition

    The e-business security solutions market is intensely competitive, subject
to rapid change and significantly affected by new product and service
introductions, consolidation and other market activities by industry
participants.

    Because of the broad functionality of our e-business security solution, we
compete currently or may in the future compete with vendors offering a wide
range of security products and services as follows:

  . companies offering commercial certification authority products and
    services such as VeriSign, Xcert and IBM in the market for issuing and
    maintaining digital certificates for use on public and private networks,
    some of whom, such as IBM and XCert, provide a product-based solution,
    while others, such as VeriSign, are primarily service providers;

  . companies, such as RSA Security and Baltimore Technologies, which offer
    PKI product solutions for enterprises;

  . established companies developing new e-business security offerings, such
    as Network Associates, which have each announced their intention to
    introduce PKI products that would be integrated with their other
    security product offerings, as well as Microsoft Corporation, which has
    announced a certificate server and other PKI-compatible products based
    on its Windows 2000 security framework;

  . other major networking vendors who may bundle digital certificates with
    their product offerings, with whom we compete on the basis of our
    ability to provide a centrally managed, real-time, comprehensive
    infrastructure with the features and functionality to support enterprise
    applications; and

  . companies in the emerging market for providing security across VPNs with
    major networking device companies, such as Lucent Technologies and
    Cisco, as well as firewall vendors such as AXENT and Check Point
    Software.

    We believe that the principal competitive factors affecting the market for
e-business security technology include technical features, ease of use,
quality/reliability, level of security, scalability, customer service and
support, and price. Although we believe that our products currently compete
favorably with respect to such factors, there can be no assurance that we can
maintain our competitive position against current and potential competitors.

Regulatory Matters

    Our products are subject to special export restrictions administered by the
governments of the United States, Canada and other countries. Our products are
also subject to import restrictions and/or use restrictions imposed by
countries such as France. Consequently, our ability to export our products to
destinations outside of the U.S. and Canada is subject to a variety of
government approvals or licensing requirements. Re-export of the products
between countries other than the U.S. and Canada may be subject to the export
control laws of those countries in addition to those

                                       44
<PAGE>

provisions of the U.S. and/or Canadian export control laws which apply to re-
exports. In light of these restrictions, depending on the country of
destination, industry sector, and/or end user, some of our products made
available abroad may contain significantly weaker encryption capabilities than
those available to customers in the U.S. and Canada, and there can be no
assurance that we will continue to be able to export our products to any
destinations outside of the U.S. and Canada. Such restrictions could
potentially have an adverse effect on our business, financial condition or
results of operations.

    On January 14, 2000, the United States Department of Commerce issued new
export regulations that apply to products that contain or use cryptography.
These regulations generally make it substantially easier to sell U.S.
encryption products abroad. In general, the new rules eliminate the constraints
on the strength of the encryption that may be exported, after a one-time review
of the product, and greatly broaden the endusers who may receive the products
without a license.

    This change should allow our products that are under the export license
authority of the U.S. to be more competitive with products of foreign
producers. However, we believe that some of our products are exempt from U.S.
export authorization and they have been marketed accordingly. U.S. producers of
products that compete with our non-U.S. products may now be able to market more
aggressively in foreign countries, offering stronger encryption and offering
products to broader industry groups.

    In substance, the new rules are as follows: software products still cannot
be exported to Cuba, Iran, Iraq, Libya, North Korea, Serbia, Sudan, Syria and
Taliban-controlled areas of Afghanistan. However, after a one-time government
review, encryption products of any key length will be exportable to non-
governmental endusers worldwide, except for the embargoed countries. Thus, it
is generally no longer necessary to follow separate rules based on encryption
key length, "recoverability", or the type of enduser or enduse. Encryption
items may be exported to foreign subsidiaries of U.S. companies without any
prior review or licensing, but new products developed from the exported
products are still subject to a one-time government technical review.

    If the government determines that an encryption product is a retail
product, then it may be exported to any user, including foreign government
endusers, in non-embargoed countries. Retail certification requires a new
application to the Commerce Department, except that previously-reviewed 56-bit
products and "finance-specific" products are considered to be retail products
without additional review.

    Export licenses are still required for exports of non-retail encryption
products to Internet and telecommunications service providers if the products
are used to provide services specifically to a foreign government or provide
non-subscriber-based bulk backbone encryption.

    Any mass market encryption product previously authorized for export under
License Exception "TSU" may be upgraded to 64-bit encryption without a new
technical review.

    The government has imposed new post-export semi-annual reporting
requirements for most export products, but this should not affect our export
sales.

    We believe, and have informed the U.S. government, that certain of our
products are exempt from U.S. encryption export restrictions under these
criteria. However, we have not obtained any formal U.S. government ruling that
any of our products produced and shipped from outside the U.S. may be exempt
from U.S. encryption export controls, and there can be no assurance that the
U.S. government will refrain from asserting jurisdiction over one or more of
our products. Such a decision by the U.S. government to assert jurisdiction
could result in penalties for past shipments and could restrict future sales of
our products outside the U.S. and Canada, having a potentially significant
adverse effect on our business, financial condition and results of operations.

                                       45

Intellectual Property

    We rely on a combination of patent, copyright, trademark and trade secret
laws, nondisclosure agreements and other contractual provisions to establish,
maintain and protect our proprietary rights. We own 11 issued U.S. patents,
along with corresponding, pending foreign patent applications, and 58 pending
U.S. patent applications relating to our products. The issued patents are and
will continue to be subject to certain license grants to others, including
Nortel Networks and its cross licensees, under patent cross license agreements.
We have copyright and trade secret rights for our products, consisting mainly
of source code and product documentation. We use a printed "shrink-wrap"
license for users of our products in order to protect certain of our copyrights
and trade secrets. We attempt to protect our trade secrets and other
proprietary information through agreements with suppliers, non-disclosure and
non-competition agreements with employees and consultants and other security
measures. See "Risk Factors".

Employees

    As of December 31, 1999, we had 545 full-time employees, 408 of whom were
employed by Entrust Technologies Limited, our Canadian subsidiary. Of our
employees, 166 were involved in research and development, 212 in sales,
marketing and business development, 97 in professional and customer support
services and 70 in administration and finance. No employees are covered by any
collective bargaining agreements, and we believe that our relationship with our
employees is good.

Properties

    Our U.S. headquarters, including our executive offices and administrative
facilities, is located in Plano, Texas, where we lease approximately 8,716
square feet of office space. We also lease approximately 69,000 square feet of
office space at our Canadian headquarters in Ottawa, Ontario, Canada, with an
additional 29,149 square feet of office space in the Ottawa area to accommodate
expected growth in administrative, sales and marketing, research and
development and operations personnel. In addition, we are currently under a
development and leasing agreement to construct additional office space in
Kanata, Ontario of approximately 145,000 square feet to accommodate future
growth. It is anticipated that this facility will be completed in the fourth
quarter of 2000. We also have offices located in London, England and Zurich,
Switzerland.

    We have sales offices in Chicago, Illinois, McLean, Virginia, Montreal,
Quebec, New York, New York and St. Louis, Missouri, a sales and business
development office in Menlo Park, California and a sales and professional
services office in Raleigh, North Carolina. We lease a sales and support office
in Bad Homburg, Germany.

Legal Proceedings

    We are subject to various legal proceedings and claims, either asserted or
unasserted, which arise in the ordinary course of business. While the outcome
of these claims cannot be predicted with certainty, management does not believe
that the outcome of any of these legal matters will have a significant adverse
effect on our consolidated results of operations or consolidated financial
position.

                          INDEPENDENT AUDITORS' REPORT

To the Directors and Shareholders of Entrust Technologies Inc:

    We have audited the consolidated balance sheets of Entrust Technologies
Inc. as of December 31, 1997 and 1998, and the related consolidated statements
of operations, shareholders' equity and comprehensive income, and cash flows
for each of the three years in the period ended December 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

    In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Entrust Technologies Inc. at
December 31, 1997 and 1998, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1998, in
conformity with generally accepted accounting principles.

          (in thousands of dollars, except share and per share data)

1. Background and Basis of Presentation

Background

    In January 1994, Nortel Networks Corporation, and its subsidiary Nortel
Networks Inc. (collectively "Nortel"), established the Secure Networks group
(the "Division") to pursue the development and sales of public key
infrastructure ("PKI") products. PKI products combine powerful public key data
encryption technology with transparent, life cycle digital certificate
management to enable users to communicate securely over public and private
networks.

    During 1996, Nortel announced its intention to create a separate company,
Entrust Technologies Inc. (the "Company") consisting of the operations of the
Division (the "Separation"). The Company was incorporated in December 1996
with nominal share capital, all of which was contributed by Nortel. At the
close of business on December 31, 1996, Nortel transferred to the Company
certain of the assets and liabilities, intellectual property, rights, licenses
and contracts of the Division of Nortel.

    In exchange, Nortel received 20,300,000 shares of the Company's Series A
Common stock, 7,700,000 shares of the Company's Special Voting stock, and cash
consideration. At the close of business on December 31, 1996, the Company
issued 260,000 shares of its Series B common stock in a private placement for
$100 per share less underwriting costs and commissions of $7.75 per share.
After the completion of the private placement, Nortel owned approximately
73.0% of the outstanding shares of the Company's common stock assuming
conversion of the Series B common stock and Series B Non-Voting common stock
into an aggregate of 13,063,836 shares of Series A common stock.

    On August 21, 1998, the Company closed its initial public offering
("IPO"), issuing 5,400,000 shares of its Common stock at an initial public
offering price of $16 per share. The net proceeds to the Company from the
offering, after deducting underwriting discounts and commissions and offering
expenses incurred by the Company, were approximately $79.1 million. See note 8
for further detail regarding changes in the issued capital of the Company.
Immediately following the IPO, Nortel owned approximately 55.3% of the
Company's Common stock.

    At September 30, 1999, Nortel owned approximately 51.2% of the Company's
Common stock.

Basis of presentation

    The historical comparative year results, comprising the statements of
operations, shareholders' equity and cash flows for the year ended December
31, 1996, represent the operations of the Division transferred to the Company
from Nortel in the Separation (the "Company Business"). These historical
results of the Division present the financial position of the Division as a
separate reporting entity independent of Nortel and its subsidiaries, as if
the Division were a stand-alone entity for that period. The 1996 consolidated
financial statements have been prepared using the historical basis in the
assets and liabilities and historical results of operations related to the
Company Business. Changes in shareholder's net investment in 1996 represent
Nortel's contribution of its net investment after giving effect to the net
income (loss) of the Division and net cash transfers to or from the Division.
The shareholder's net investment was not transferred to the Company as part of
the Separation.

    The 1996 consolidated financial statements, presented here for comparison
purposes, include certain Nortel corporate costs that were allocated to the
Division using procedures deemed

                                      F-8
<PAGE>

                           ENTRUST TECHNOLOGIES INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
           (in thousands of dollars, except share and per share data)

appropriate for the nature of the expenses involved. The procedures utilized
various allocation bases such as invested net assets, number of employees and
related payroll costs, and direct effort expended. Management believes that the
allocations reflected in the 1996 consolidated financial statements are
reasonable, but they were not necessarily indicative of the costs that would
have been incurred had the Division functioned as a stand-alone company. No
Nortel corporate costs were allocated to the Company, in this way, in the years
ended December 31, 1997 and 1998 or the nine months ended September 30, 1999.
After the Separation, Nortel continued to provide certain "corporate" services
to the Company. Fees charged for such services are based on Nortel's internal
usage-based fee structures where applicable or Nortel's direct cost of
services, including total compensation and out-of-pocket expenses.

2. Significant Accounting Policies

Consolidation

    The consolidated financial statements of the Company include the accounts
of its majority-owned Canadian subsidiary, Entrust Technologies Limited, its
wholly-owned U.K. subsidiary, Entrust Technologies (UK) Limited, its wholly-
owned German subsidiary, Entrust Technologies GmbH, and, its wholly-owned Swiss
subsidiary, r/3/ Security Engineering AG. The minority interest in the Canadian
subsidiary has been insignificant to date. All significant intercompany
transactions and accounts are eliminated in consolidation.

Translation of foreign currencies

    The accounts of the Company's subsidiaries have been translated into U.S.
dollars. Assets and liabilities have been translated at the exchange rates in
effect at the balance sheet date. Revenues, expenses and cash flow amounts are
translated at average rates for the period. The resulting translation
adjustments are included in comprehensive income as a separate component of
shareholders' equity. Gains and losses from foreign currency transactions are
included in the determination of net income and are not material.

    The Company does not use hedging or derivatives and, as a result, may be
exposed to currency translation adjustments in the future. However, the Company
transacts the majority of its international sales in U.S. dollars, except for
Canada where the Company has both significant costs and revenues, which the
Company believes mitigates the potential impact of currency fluctuations.

    The Company is subject to foreign currency exchange risk in the form of
exposures to changes in currency exchange rates between the United States and
Canada, Germany, Switzerland and the United Kingdom. Management periodically
reviews the potential financial impact of this risk and currently believes that
the Company is not subject to significant potential losses as a result.

Revenue recognition

    The Company generates revenues primarily from licensing the rights to its
software products to end-users and from sublicense fees from resellers. The
Company also generates revenues from consulting, training and post-contract
support ("maintenance"). In October 1997, the American Institute of Certified
Public Accountants ("AICPA") issued Statement of Position ("SOP") No. 97-2,
"Software Revenue Recognition", which the Company adopted, effective January 1,
1998. Such

                                      F-9
<PAGE>

                           ENTRUST TECHNOLOGIES INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
           (in thousands of dollars, except share and per share data)

adoption had no effect on the Company's method of recognizing revenues. Prior
to 1998, the Company's revenue recognition policy was in accordance with the
provisions of the preceding authoritative guidance provided by SOP 91-1
"Software Revenue Recognition".

    Revenues from perpetual software license agreements are recognized as
revenue upon receipt of an executed license agreement, or an unconditional
order under an existing license agreement, and shipment of the software, if
there are no significant remaining vendor obligations, collection of the
receivable is probable and payment is due within twelve months.

    Revenues from maintenance services are recognized ratably over the term of
the maintenance period, which is typically one year. If maintenance services
are included free of charge or discounted in a license agreement, such amounts
are unbundled from the license fee at their fair market value based upon the
value established by independent sales of such maintenance to customers.
Revenues from the sale of Entrust.net Web server certificates are also
recognized ratably over the term of the certificate (typically one to two
years).

    Consulting and training revenues are generally recognized as the services
are performed. Consulting services are typically performed under separate
service agreements and are usually performed on a time and materials basis.
Such services primarily consist of implementation services related to the
installation and deployment of the Company's products and do not include
significant customization or development of the underlying software code.

    The Company uses the percentage of completion method to account for large
custom development contracts. Under this method, the Company recognizes revenue
and profit as the work on the contract progresses. Revenues are recognized by
applying the percentage of the total cost incurred to date divided by the total
estimated contract cost to the total contract value, and any projected loss is
recognized immediately. The total project cost estimates are reviewed on a
regular basis.

Cost of revenues

    Cost of licenses includes the cost of media, product packaging,
documentation and other production costs and third-party royalties.

    Cost of services and maintenance consists primarily of salaries, benefits
and allocated overhead costs related to consulting, training and customer
support personnel, including the cost of third-party consultants engaged by the
Company.

Research and development costs

    To date the Company has not capitalized any software development costs
under Statement of Financial Accounting Standards ("SFAS") No. 86, "Accounting
for the Costs of Computer Software to be Sold, Leased, or otherwise Marketed".
The Company has defined attainment of technological feasibility as completion
of a working model. The period of time beginning with the establishment of a
working model and ending when a product is offered for sale is typically very
short. Accordingly, costs that were eligible for capitalization were
insignificant.

Cash and cash equivalents

    The Company considers all highly liquid investments with original
maturities of three months or less to be cash equivalents. The Company's cash
and cash equivalents are maintained with a bank and a brokerage institution.
Prior to January 1, 1997, the Company, as a division of Nortel, participated in
the Nortel cash management system and, accordingly, did not maintain cash
balances other than minimal amounts.

Marketable investments

    Marketable investments consist of investments in a strategic cash
management account. This account is invested primarily in highly rated
corporate securities, in securities guaranteed by the U.S. government or its
agencies and highly rated municipal bonds primarily with a remaining maturity
of not more than 12 months. The Company has the intent and ability to hold all
investments until maturity. Therefore, all such investments are classified as
held to maturity investments and stated at amortized cost. At December 31, 1997
and 1998 and September 30, 1999 (unaudited) the amortized cost of the Company's
investments approximated fair value.

    The Company's marketable investments consist of the following:

Accounts receivable
    The Company's customer base consists primarily of large, well-established
companies or government agencies. Five customers accounted for approximately
55% and 45% of accounts receivable as of December 31, 1997 and 1998,
respectively, and approximately 44% as of September 30, 1999 (unaudited). The
Company performs ongoing credit evaluations of its customers, and generally,
does not require collateral from its customers to support accounts receivable.
Requests to extend significant credit to customers are reviewed and approved by
senior management. The Company maintains an allowance for potential losses due
to credit risk, but has not experienced significant write-offs. Management
believes that the reserves for losses are adequate. The following table
summarizes the changes in the allowance for doubtful accounts:

Other receivables

    Other receivables include federal income tax and Canadian goods and
services tax refunds of $1,644 and $973 at December 31, 1997 and 1998,
respectively, and $1,139 at September 30, 1999 (unaudited). Other receivables
also includes work-in-process relating to a long-term percentage-of-completion
contract of $432 and $826 at December 31, 1997 and 1998, respectively, and
$1,199 at September 30, 1999 (unaudited).

Property and equipment

    Property and equipment is stated at cost. Depreciation is calculated
generally using the straight-line method over the estimated useful lives of the
assets. The expected useful lives of the furniture and fixtures, computer and
telecom equipment and software is three to five years and the remaining term of
the facility lease for leasehold improvements.

    When assets are sold or retired, the cost and related accumulated
depreciation are removed from the accounts and any resulting gain or loss is
included in operations. Maintenance and repairs are charged to operations as
incurred.

    Assets are reviewed for impairment on the basis of undiscounted cash flows.
If the cash flows are less than the asset's carrying value, the asset is
written down to its fair value.

Goodwill and other assets

    Goodwill is stated net of accumulated amortization of $356 and $890 at
December 31, 1998 and September 30, 1999 (unaudited), respectively. Goodwill is
being amortized on a straight-line basis over five years. Included in other
long-term assets is an investment of $393 at December 31, 1998 and September
30, 1999 (unaudited), which represents a 10% ownership interest in Entrust
Japan. Other long-term assets also include costs incurred of $1,068 at
September 30, 1999 (unaudited) primarily for licenses used by the Company to
provide services. These costs are amortized straight-line over three to four
years and are stated net of accumulated amortization of $56 at September 30,
1999 (unaudited).

Income taxes

    The Company uses the asset and liability method to account for income
taxes. Deferred income tax assets and liabilities are recognized for the future
tax consequences attributable to differences between the carrying amounts of
existing assets and liabilities for accounting purposes, and their respective
tax bases. Deferred income tax assets and liabilities are measured using
statutory tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled. The effect
on deferred income tax assets and liabilities of a change in statutory tax
rates is recognized in net income in the year of change. A valuation allowance
is recorded for those deferred income tax assets whose recoverability is not
sufficiently likely. As the Company operated as a division of Nortel in 1996,
it did not file separate income tax returns. Income tax expense has been
estimated based upon an application of Nortel's effective tax rate for that
period.

Stock-based compensation

    Stock-based compensation arising from stock option grants is accounted for
by the intrinsic value method under Accounting Principles Board ("APB") Opinion
No. 25. Statement of Financial Accounting Standards ("SFAS") No. 123 encourages
(but does not require) the cost of stock-based

           (in thousands of dollars, except share and per share data)

compensation arrangements with employees to be measured based on the fair value
of the equity instrument awarded. As permitted by SFAS No. 123, the Company
applies APB Opinion No. 25 to its stock-based compensation awards to employees
and discloses in Note 9 the required pro forma effect on net income and
earnings per share.

Net income (loss) per share

    Basic net income (loss) per share is computed by dividing the net income
(loss) by the weighted average number of shares of Common stock of all classes
outstanding during the period. Diluted net income (loss) per share is computed
by dividing the net income (loss) by the weighted average number of shares of
Common stock and potential Common stock outstanding, and when dilutive,
exchangeable Special Voting stock on an as-if exchanged basis, and options to
purchase Common stock using the treasury stock method. The dilutive effect of
the exchangeable Special Voting stock and the options to purchase Common stock
are excluded from the computation of diluted net income (loss) per share if
their effect is antidilutive. For the year ended December 31, 1998, the
antidilutive effect excluded from the diluted net loss per share computation
due to the exchangeable Special Voting stock outstanding was 6,767,673 shares,
conversion rights of Series B was 1,687,096 shares, and options to purchase
Common stock was 5,437,769 shares. For the nine months ended September 30, 1998
(unaudited) the antidilutive effect excluded from the diluted net loss per
share computation due to the exchangeable Special Voting stock outstanding was
7,304,467 shares, conversion rights of Series B was 2,249,600 shares, and the
option to purchase Common stock was 5,156,750 shares.

    Net income (loss) per share has been calculated as follows:

Concentration of credit risk

    Financial instruments that potentially subject the Company to market and
credit risk consist principally of cash equivalents, marketable investments and
accounts receivable. The Company has investment policies that limit the amount
of credit exposure to any one issuer and restrict placement of these
investments to issuers evaluated as credit worthy. The Company maintains its
cash equivalents, and marketable investments, with high quality financial
institutions and investment managers. The Company performs periodic reviews of
the credit standing of its investments and the financial institutions managing
those investments.

Recent pronouncements

    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"), which establishes accounting and reporting standards for derivative
instruments. SFAS No. 133 is effective beginning in 2000. The Company currently
does not use hedging or derivatives and, as a result, does not anticipate any
impact on the financial statements.

    In December 1998, the AICPA issued SOP No. 98-9, "Modifications of SOP 97-
2, Software Revenue Recognition, with Respect to Certain Transactions" ("SOP
No. 98-9"). SOP No. 98-9 requires recognition of revenue using the "residual
method" in a multiple-element software arrangement, whereby the total fair
value of undelivered elements is deferred and recognized in accordance with the
provisions of SOP No. 97-2, "Software Revenue Recognition". The Company will be
required to implement the provisions of SOP No. 98-9 beginning in 2000. The
Company does not expect the adoption of SOP No. 98-9 to have a material impact
on its results of operations.

Use of estimates

    The preparation of the consolidated 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 consolidated
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

Unaudited interim financial information

    The consolidated financial statements as of and for the nine months ended
September 30, 1998 and 1999 are unaudited but, in the opinion of management,
include all adjustments, consisting only of normal recurring accruals,
necessary for a fair presentation of the results for such periods. The results
of operations for the nine months ended September 30, 1999 are not necessarily
indicative of results to be expected for the full fiscal year.

3. Acquisition of r/3/ Security Engineering AG and Acquired
  In-Process Research and Development

    On June 8, 1998, the Company completed the acquisition of r/3/ Security
Engineering AG ("r/3/"), a company based in Zurich, Switzerland which provides
consulting, applied research and product development services related to
commercial security and encryption solutions. The Company acquired all the
outstanding shares of r/3/ for an aggregate purchase price of $23,774, which
included approximately $4,391 in cash, $17,013 representing 1,167,288 shares
of Redeemable Series A common stock (subsequently converted into Common stock
upon the closing of the Company's initial public offering), approximately $994
in assumed net liabilities and acquisition expenses, and approximately $1,376
of adjustments to the June 8, 1998 opening balance sheet of r/3/ to record the
acquired assets and liabilities at fair value.

    This acquisition has been accounted for under the purchase method of
accounting. In connection with the purchase price allocation, the Company
obtained an independent appraisal of the intangible assets which indicated
approximately $20,208 of the acquired intangible assets consisted of in-
process product development. The development of these projects had not reached
technological feasibility and the technology has no alternative future use.
Further, management estimates that related development costs will continue to
be incurred and, accordingly, the $20,208 was included as an expense in the
consolidated statement of operations for the year ended December 31, 1998.
Goodwill of $3,566 and $450 was recorded as a result of this acquisition, in
1998 and 1999 (unaudited), respectively.

    The following unaudited pro forma data summarize the combined results of
operations of Entrust Technologies Inc. and r/3/ as if the acquisition had
taken place as of the beginning of the years presented, and accordingly,
excludes the $20,208 write-off of in-process research and development in 1998
as it would have been a charge to beginning retained earnings, and includes a
full year of goodwill amortization for each year presented.

Employee Stock Purchase Plan

    The Company's 1998 Employee Stock Purchase Plan (the "Purchase Plan") was
adopted by the Board of Directors in July 1998 and approved by the stockholders
of the Company in August 1998. The Purchase Plan authorized the issuance of up
to a total of 400,000 shares of Common stock to participating employees.

    All employees of the Company, including directors of the Company who are
employees, and all employees of any participating subsidiaries whose customary
employment is more than 20 hours per week and more than five months in any
calendar year are eligible to participate in the Purchase Plan.

    Under the terms of the Purchase Plan, the price per share paid by each
participant on the last day of the Offering Period is an amount equal to 90% of
the fair market value of the Common stock on either the first day or the last
day of the Offering Period, whichever is lower. On December 10, 1999, the
Company's Board of Directors made a change in the Purchase Plan to lower the
price per share paid to an amount equal to 85% of the fair market value of the
Common stock on either the first day or last day of the Offering Period,
whichever is lower, effective for the next Offering Period beginning February
1, 2000.

    The Purchase Plan terminates on July 21, 2000 or such earlier date as the
Board determines. Upon termination of the Purchase Plan all amounts in the
accounts of participating employees will be promptly refunded.

Stock-based Compensation

    The Company applies APB Opinion No. 25 and related interpretations in
accounting for its employee stock-based compensation plans. Accordingly,
compensation expense has been recognized for its stock-based compensation plans
in the year ended December 31, 1998 because the exercise price of some options
granted in that period were determined, for accounting purposes, to be below
the fair value of the underlying stock as of the grant date for such stock
options. In connection with the granting of these options, the Company has
recorded unearned deferred

compensation of $784 for the year ended December 31, 1998. This amount is being
amortized over the vesting period of four years from the date of grant, with
$149 amortized into compensation expense as of December 31, 1998 and an
additional $147 amortized into compensation expense in the nine months ended
September 30, 1999 (unaudited). For all other periods disclosed, the exercise
price of each option granted was equal to the fair value of the underlying
stock at the date of grant. Had compensation costs for the Company's Stock
Incentive Plan been determined based on the fair value at the grant date for
awards under the Plan, consistent with the methodology prescribed under SFAS
123, the Company's net income (loss) and net income (loss) per share would have
been as follows, on a pro forma basis.

    The fair value of all options granted prior to the Company's initial public
offering on August 17, 1998 were estimated as of the date of grant using the
minimum value model. The fair value of all options granted subsequent to the
Company's initial public offering were estimated as of the date of grant using
the Black-Scholes option pricing model. The following weighted average

totaling $332 and $2,076, respectively, and $1,949 and $221 for the nine months
ended September 30, 1998 and 1999 (unaudited), respectively. Sales to Nortel-

    During the years ended December 31, 1997 and 1998 and the nine months ended
September 30, 1999 (unaudited), the Company reimbursed Nortel for expenses paid
by Nortel on behalf of the Company, net of revenues collected by Nortel on

accounts receivable included $1,724 related to Nortel. At September 30, 1999
(unaudited), there were no amounts receivable from Nortel and $32 receivable
from Nortel-affiliated companies.

Legal proceedings

    The Company is subject to various legal proceedings and claims, either
asserted or unasserted, which arise in the ordinary course of business. While
the outcome of these claims cannot be predicted with certainty, management does
not believe that the outcome of any such legal matters will have a material
adverse effect on the consolidated results of operations or consolidated
financial position.

    On February 19, 1999, Surety Technologies, Inc. (Surety) filed Civil Action
99-203 against the Company alleging that the Entrust/Timestamp product
infringed various claims of U.S. Patent Re 34,954 (the "954 Patent"). In a
verdict returned on November 3, 1999, a federal jury found that all of

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
           (in thousands of dollars, except share and per share data)

the claims of the 954 Patent asserted by Surety against the Company were
invalid for reasons of both anticipation and obviousness. As a result of the
jury's decision, Surety's complaint has been dismissed with prejudice. On
November 4, 1999, judgment was entered in favor of the Company in the United
States District Court for the Eastern District of Virginia in Civil Action 99-
203.

12. Employee Savings Plan

    The Company has a defined contribution retirement savings plan covering
substantially all of its full-time employees. This plan qualifies under Section
401(k) of the Internal Revenue Code for participating U.S. based employees. The
Company matches 50% of employee contributions up to 3% of their individual
compensation. Matching contributions made by the Company totaled $183 and $383
for the years ended December 31, 1997 and 1998, respectively, and $442 for the
nine months ended September 30, 1999 (unaudited).

13. Segment, Geographic and Major Customer Information

Segment information

    The Company conducts business in one operating segment; namely, the design,
production and sale of software products and related services for encryption
and digital signature. The nature of the Company's different products and
services is similar and, in general, the type of customers for those products
and services is not distinguishable.

    The Company does, however, prepare information for internal use by the
Chief Operating Decision Maker ("CODM"), the President and Chief Executive
Officer, on a geographic basis. Accordingly, under SFAS 131, the Company has
included a summary of the segment financial information reported to the CODM as
follows in the next section regarding geographic information. The Company's
CODM does not view geographic segment results below net income (loss) before
income taxes and, therefore, the provision for income taxes is not broken out
by geographic segment below. The accounting policies of the reportable
geographic segments are the same as those described in the summary of
significant accounting policies.

Geographic information

    Revenues are attributed to specific geographical areas based on where the
sales order originated. Long-lived assets and total assets of the Company are
those that are identified with operations in the respective geographic areas.

Major customer information

    In 1996, three customers accounted for an aggregate of 64% of revenues for
the year, and individually these customers accounted for 29%, 20% and 15% of
revenues for that year. In 1997, three customers accounted for an aggregate of
42% of revenues. One of these customers was the same customer who accounted for
29% of 1996 revenues and this customer accounted for 19% of revenues for 1997.
The other two major customers in 1997 accounted for 12% and 11% of revenues,
respectively. In 1998, no individual customer accounted for 10% or more of
revenues. For the nine months ended September 30, 1999 (unaudited) there was a
single customer which accounted for 26% of revenues, and no other customers
accounted for 10% or more of revenues.

    If the underwriters sell more shares than the total number set forth in the
table above, the underwriters have an option to buy up to an additional 305,625
and 916,875 shares from us and a selling stockholder, respectively, to cover
such sales. They may exercise that option for 30 days. If any shares are
purchased pursuant to this option, the underwriters will severally purchase
shares in approximately the same proportion as set forth in the table above.

    The following tables show the per share and total underwriting discounts
and commissions to be paid to the underwriters by us and the selling
stockholders. Such amounts are shown assuming both no exercise and full
exercise of the underwriters' option to purchase 1,222,500 additional shares.

    Shares sold by the underwriters to the public will initially be offered at
the initial price to public set forth on the cover of this prospectus. Any
shares sold by the underwriters to securities dealers may be sold at a discount
of up to $   per share from the initial price to public. Any of those
securities dealers may resell any shares purchased from the underwriters to
other brokers or dealers at a discount of up to $   per share from the initial
price to public. If all the shares are not sold at the initial price to public,
the representatives may change the offering price and the other selling terms.

    We and the selling stockholders have agreed with the underwriters not to
dispose of or hedge any of our common stock or securities convertible into or
exchangeable for shares of common stock during the period from the date of this
prospectus continuing through the date 90 days after the date of this
prospectus, except with the prior written consent of the representatives. This
agreement does not apply to any existing employee benefit plans.

    In connection with the offering, the underwriters may purchase and sell
shares of common stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the underwriters of a greater
number of shares than they are required to purchase in this offering.
Stabilizing transactions consist of certain bids or purchases made for the
purpose of preventing or retarding a decline in the market price of the common
stock while the offering is in progress.

    The underwriters also may impose a penalty bid. This occurs when a
particular underwriter repays to the underwriters a portion of the underwriting
discount received by it because the representatives have repurchased shares
sold by or for the account of such underwriter in stabilizing or short covering
transactions.

    These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of the common stock. As a result, the price of the
common stock may be higher than the price that otherwise might exist in the
open market. If these activities are commenced, they may be discontinued by the
underwriters at any time. These transactions may be effected on the Nasdaq
National Market, in the over-the-counter market or otherwise.

    As permitted by Rule 103 under the Securities Exchange Act of 1934, some
underwriters and selling group members that, if any, may act as "passive" are
market makers in the common stock, which means they may make bids for or
purchases of common stock in the Nasdaq National Market until a stabilizing bid
has been made. Rule 103 generally provides that:

  . a passive market maker's net daily purchases of the common stock may not
    exceed 30% of its average daily trading volume in such securities for
    the two full consecutive calendar months, or any 60 consecutive days
    ending within the 10 days, immediately preceding the filing date of the
    registration statement of which this prospectus forms a part;

  . a passive market maker may not effect transactions or display bids for
    common stock at a price that exceeds the highest independent bid for the
    common stock by persons who are not passive market makers; and

  . bids made by passive market makers must be identified as such.

    A prospectus in electronic format will be made available on the web sites
maintained by one or more of the lead managers of this offering and may also be
made available on web sites maintained by other underwriters. The underwriters
may agree to allocate a number of shares to underwriters for sale to their
online brokerage account holders. Internet distributions will be allocated by
the lead managers to underwriters that may make Internet distributions on the
same basis as other allocations.

    We estimate that the total expenses of this offering, excluding
underwriting discounts and commissions, will be approximately $750,000. We will
pay for all of such expenses.

    We and the selling stockholders have agreed to indemnify the several
underwriters against certain liabilities, including liabilities under the
Securities Act of 1933.

Item 15. Indemnification of Directors and Officers

    Section 2-418 of the General Corporation Law of Maryland (the "Maryland
Law") provides that, unless a corporation's charter includes a provision which
restricts or limits the corporation's right to indemnify its officers and
directors, the corporation may indemnify a director or officer with respect to
proceedings instituted against such officer or director by reason of his or her
service in that capacity, unless the act or omission in question was material
and was committed in bad faith or was the result of active and deliberate
dishonesty, unless the director or officer received an improper personal
benefit or unless the director or officer had reasonable cause to believe that
the act or omission was unlawful. The Registrant's Articles of Incorporation
and Bylaws provide that the Registrant shall indemnify and advance expenses to
its currently acting and its former directors to the fullest extent permitted
by the Maryland Law and that the Registrant shall indemnify and advance
expenses to its officers to the same extent as its directors and to such
further extent as is consistent with law. However, nothing in the Articles of
Incorporation or Bylaws of the Registrant protects or indemnifies a director,
officer, employee or agent against any liability to which he would otherwise be
subject by reason of willful misfeasance, bad faith, gross negligence or
reckless disregard of the duties involved in the conduct of his office. To the
extent that a director has been successful in defense of a proceeding, unless
limited by charter, the Maryland Law provides that he shall be indemnified
against reasonable expenses incurred in connection therewith.

    The Underwriting Agreement, a form of which is filed as Exhibit 1 to this
Registration Statement on Form S-3, provides that the Underwriters are
obligated under certain circumstances to indemnify directors, officers and
controlling persons of the Registrant against certain liabilities, including
liabilities under the Securities Act of 1933, as amended. Reference is made to
the form of Underwriting Agreement.

    Two of the directors of the Registrant are also officers of Nortel Networks
Corporation ("NNC"), a shareholder of the Registrant, and are serving on the
Registrant's Board of Directors at the request of NNC. Pursuant to NNC's
Bylaws, NNC will indemnify its officers when they are acting at NNC's

                                      II-1
<PAGE>

request as directors of a corporation of which NNC is a shareholder, provided
that such officers acted honestly, in good faith and had reasonable grounds to
believe their conduct was lawful.

Item 17. Undertakings

    The undersigned Registrant hereby undertakes that:

      (1) For purposes of determining any liability under the Securities Act
  of 1933, the information omitted from the form of prospectus filed as part
  of this registration statement in reliance upon Rule 430A and contained in
  a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act will be deemed to be part of this
  registration statement as of the time it was declared effective.

      (2) For the purpose of determining any liability under the Securities
  Act of 1933, each post-effective amendment that contains a form of
  prospectus shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at
  that time shall be deemed to be the initial bona fide offering thereof.

                                      II-2
<PAGE>

    The Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the Registrant's
annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act
of 1934 (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934)
that is incorporated by reference in this Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
therein and the offering of such securities at the time shall be deemed to be
the initial bona fide offering thereof.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the indemnification provisions described herein, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

    Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this Amendment No. 1 to
the Registration Statement to be signed on its behalf by the undersigned,
thereunto duly authorized, in Plano, Texas, on this 3rd day of February, 2000.

                               RELEASE AGREEMENT




This agreement is made between:

     BRADLEY ROSS, for himself, his heirs, dependents, executors,
     administrators, successors and assigns; hereinafter referred to as
     "Employee",

                                      and

     ENTRUST TECHNOLOGIES INC. and ENTRUST TECHNOLOGIES LTD.; hereinafter
     referred to as "ENTRUST".


Whereas the Parties wish to terminate the employment relationship between
Entrust and Employee, it is therefore agreed as follows:

IN CONSIDERATION of the payments less the required deductions for income taxes
and other statutory deductions, and other good and valuable consideration as
herein, Employee agrees as follows:

1)   Employee agrees that the contract of employment between himself and ENTRUST
     will be terminated on January 31, 2000 with notice received on June 1,
     1999.

2)   Employee wholly releases ENTRUST, its successors and assigns, its officers
     and directors, shareholders, agents and employees and its affiliated and
     associated companies and assigns, of and from any and all actions, causes
     of actions, complaints, debts, dues, warranties, claims or demands for any
     loss, losses or damage whatsoever in existence prior to, on or after the
     date hereof, directly or indirectly arising from his employment with
     ENTRUST or the
<PAGE>

     termination thereof. Without limiting the generality of the foregoing,
     Employee acknowledges that the said payment is in satisfaction of all
     claims for damages for wrongful dismissal including all non-salary benefits
     ordinarily provided to or on his behalf in respect of the employment,
     vacation pay, any and all expenses whether incurred before, on or after the
     date hereof in respect of the employment and as more particularly described
     in his International Assignment Agreement dated September 30, 1998 and his
     Offer of Employment dated November 18, 1996 and any and all claims which
     Employee may have had under the Employment Standards Act and the Human
     Rights Code of Ontario or the Canada Labour Code.

3)   Employee agrees not to make any claims or take any proceedings against any
     other person or corporation which might claim contribution or indemnity
     from ENTRUST under the provisions of any statute or otherwise with respect
     to any matter which arose or may have arisen between ENTRUST and Employee
     at the present time.

4)   Employee agrees to indemnify and save harmless ENTRUST from and against any
     and all claims, actions, causes of action, debts or demands under the
     Income Tax Act for or in respect of withholding taxes relating to the
     cessation of his employment together with any interest or penalties
     relating thereto and any costs or expenses incurred by ENTURST in defending
     such claim, cause of action, demand, debt or assessment by Revenue Canada
     or by any other taxing authority.

5)   Employee agrees that the terms of his non-compete agreement described in
     his employment offer letter dated November 18, 1996, which provide that he
     may not compete with ENTRUST, are hereby modified to include Europe in
     addition to Canada and the United States and will take effect on his
     termination date of January 31, 2000 and remain effective
<PAGE>

     until January 31, 2001. Notwithstanding the foregoing, if a court finds
     that the addition of Europe make the non- competition terms unenforceable,
     the parties agree that Section 5 is severable from this agreement and the
     non-competition terms.

6)   Employee agrees to resign as member of the Board of Security Engineering AG
     effective July 15, 1999 or as soon as notice of a replacement being
     appointed is received, whichever comes first.

7)   Employee understands that, as an employee, he remains subject to ENTRUST's
     insider trading restrictions until January 31, 2000 and that although he is
     no longer subject to SEC Section 16b reporting, he will continue to abide
     by the trade restrictions in place for 16b Officers until January 31, 2000.

8)   Employee agrees to return to Entrust any and all company property on or
     before the termination date and agrees to fulfill his obligations as a
     departing employee not to disclose confidential or proprietary information.
     Employee continues to be bound by the Conflict of Interest and the
     Intellectual Property and Confidentiality agreements. Furthermore, Employee
     will not speak of Entrust or Nortel or any of their employees, officers or
     representatives, in disparaging terms nor in any other negative way
     communicate about his employment with Entrust.

9)   Employee acknowledges and agrees that the payment referred to herein does
     not represent any admission or recognition of liability by ENTRUST.

10)  Employee further acknowledges and agrees that the terms of this Release
     Agreement are fully understood by him, that Employee has had independent
     legal representation in connection with this Release Agreement and that
     this Release Agreement is voluntarily entered into by him.
<PAGE>

IN CONSIDERATION of the covenants made above, ENTRUST agrees to provide as
follows:

1)   Eight months notice to Employee of intent to terminate employment, provided
     on June 1, 1999 with termination date of January 31, 2000, whereby Employee
     shall work through the notice period.

2)   Lump sum payment to Employee of CHF53,334.00 less applicable taxes, plus

     months benefits compensation. An additional lump sum payment of CHF
     7,500.00 will also be provided in lieu of relocation expenses. Vacation,

     paid house rental in Zurich, storage of household goods in Canada, home

     clarity, ENTRUST will deduct from rental proceeds any actual repair or
     maintenance up to CDN$2,500, with remaining expenses, if any, to be
     Employee's responsibility. Condo fees of CDN$355.67 per month can be

Conformity Plans and Specifications shall be initialed by both parties and shall
be deemed to be incorporated by reference as part of this Development Agreement.

     Specifications, for Entrust's acceptance. Upon acceptance by Entrust, the
     architectural and interior design plans and specifications forming part of

     building permits necessary to construct and permit occupancy of the
     Premises in accordance with the Construction Plans and Specifications, the
     Tenant Fit-Up Plans and Specifications and the Development Schedule. The

     Base Building Core & Shell and Entrust shall bear the costs (including,
     without limitation, applicable development charges) associated with

3.4  Change Orders
     -------------

Prior to completion of construction, Entrust may from time to time in its
discretion order modifications to the Preliminary Plans and Specifications, the
Progress Drawings and Specifications, the Construction Plans and Specifications
and the Tenant Fit-Up Plans and Specifications, subject to an appropriate
extension of the Substantial Performance Date (if applicable).  Each
modification requested by Entrust is subject to the following:

(a)  the consent of the Developer (which consent may only be withheld as set out
     in Section 2 of Schedule "F" of the Lease);

(b)  if the modification increases or decreases total cost of the Base Building
     Core & Shell, then the cost of the modification will be dealt with as set
     out in Section 2 of Schedule "F" of the Lease;

(c)  if consented to, the cost of the modification is to be dealt with as set
     out in Section 4.1 (c) of this Development Agreement.

If at any one time Entrust requests modifications which both increase and
decrease costs, then only the net cost effect of those modifications shall be
considered, provided that the cost effect of modifications to the Base Building
Core & Shell and to the Tenant Fit-Up shall be considered separately.

Entrust also may, in its discretion, require certain immaterial (i.e., at no
change of cost or change in time or material change in design) field
modifications in the Tenant Fit-Up Plans and Specifications without the consent
of the Developer.  The Construction Plans and Specifications shall not be
amended by the Developer in any manner which materially affects the Tenant Fit-
Up Plans and Specifications without the written consent of Entrust.

Except for immaterial field modifications to the Tenant Fit-Up Plans and
Specifications as described above, approval of all modifications requested by
Entrust to or affecting the Construction Plans and Specifications or the Tenant
Fit-Up Plans and Specifications and approval of modifications requested by the
Developer to or affecting the Tenant Fit-Up Plans and Specifications must be in
writing and signed or initialed by both parties through their authorized
construction representatives from time to time.  As of the date of this
Development Agreement, Entrust's authorized representative is Carol Lim or David
Wagner and the Developer's authorized representative is Jonathan Wener, Douglas
Pascal, Oakley Semple or Wayne Jennings.  Each party shall give written notice
to the other of any change in the individuals who have full binding authority to
approve modifications.  If a party withdraws the authority of any such
individual by written notice to the other party, then that withdrawal is not
valid unless the notice specifies a new authorized construction representative
for the withdrawing party.  The Developer shall obtain approval of one of
Entrust's authorized construction representatives for any modifications or
contemplated modifications (the cost of investigating which is Entrust's)
requested by Entrust to or affecting the Construction Plans and Specifications
or the Tenant Fit-Up Plans and
<PAGE>

                                       8


Specifications and for any modifications requested by the Developer to or
affecting the Tenant Fit-Up Plans and Specifications and the Developer is solely
responsible for any changes not approved by one of Entrust's authorized
representatives.

If the Developer forecasts that any changes or modifications requested by
Entrust may cause a delay in meeting the Substantial Performance Date, then the
Developer shall give Entrust notice of the estimated number of Delay Days (which
Delay Days are to be deemed to cause an Entrust Delay).  If Entrust decides to
have the Developer proceed with the change or modification, then the Substantial
Performance Date shall be extended by the actual number of Delay Days.

From and after the execution of this Development Agreement, the Developer shall
submit to Entrust monthly written reports describing: (i) the status of the
Developer's obligations under this Development Agreement; (ii) the status of

     to attend at the Premises together with a representative of the Developer
     for the purpose of carrying out a joint inspection with the Developer and
     the Developer's representative of the Substantially Performed work to which
     the Developer's notice relates and agreeing on a list of items to be
     rectified or completed.

(d)  Dispute as to Deficiency List  If either party disputes the inclusion or
     -----------------------------
     exclusion of any item from the parties' joint deficiency list, then the
     matter shall be referred to and determined by an arbitration conducted in
     accordance with section 12.  If applicable, this subsection constitutes the
     required submission to arbitration.

(e)  Correction of Deficiencies  In any event, the Developer shall promptly
     --------------------------
     commence and diligently pursue to correction and completion the work set
     forth in the joint deficiency list and shall complete it within thirty (30)
     calendar days after the preparation of the joint deficiency list (except
     for items which cannot be completed within that thirty (30) day period for
     reasons beyond the Developer's reasonable control, provided the Developer
     shall diligently pursue the correction and completion of those items).

(f)  Deemed Acceptance  Upon the expiration of the five (5) day period referred
     -----------------
     to in paragraph 3.8(c), Entrust shall be deemed to have accepted the
     Substantially Performed work to which the Developer's notice relates and
     the Developer shall be deemed to have satisfied all of its obligations in
     respect to it, save and expect for the uncompleted and incorrectly
     completed items described in the joint deficiency list and latent defects.
     Entrust's deemed acceptance of that work and the Developer's deemed
     satisfaction of its obligations in respect to it does not diminish in any
     way the Developer's warranties and guarantees given to Entrust pursuant to
     subsection 3.7.

3.9  Remedies For Failure to Deliver Premises on the Substantial Performance
     -----------------------------------------------------------------------
     Date
     ----

Entrust shall have no right to terminate the Lease Agreement or to abate rent
due under the Lease Agreement for any failure by the Developer to meet the
Substantial Performance Date, as extended for Force Majeure Delay or Entrust
Delay.  The effect of Force Majeure Delay, Entrust Delay and the failure of the
Developer to meet the Substantial Performance Date (as extended for Force
Majeure Delay or Entrust Delay) on the determination of the Commencement Date is
governed by the Lease Agreement.

The Developer agrees that it shall assign a project manager satisfactory to
Entrust, acting reasonably, for the construction of the Base Building Core &
Shell as well as the Tenant Fit-Up and that such project manager shall be
dedicated on a full-time basis to such construction.  Entrust hereby confirms
that Stephen Martin is a project manager satisfactory to Entrust.

      Construction Manager" (CCA 5 - 1988), except as otherwise agreed in
      writing.

(c)   The Developer shall contribute up to the sum of Fifteen Dollars ($15.00)

<PAGE>

                                       14


     The costs to be paid from that contribution include the costs of all plans
     and permits, the cost of insurance for the Tenant Fit-Up and the costs
     described in the Tenant Fit-Up economics schedule (Section A-4- Schedule
     "B") in the Project Definition Binder, together with those fees set out in

the design development phase and the tender documents phase. After preparation
of the budget for Tenant Fit-Up and acceptance thereof by Entrust, acting
reasonably, the budget is subject to revision by the Developer during the course
of development to reflect the latest cost estimates received by it, having
regard to the progression of the schematic design phase, the design development
phase and the tender documents phase, subject to review and acceptance of those
cost estimates by Entrust, acting reasonably. The budget shall be monitored and
controlled by the Developer so that it is not exceeded, other than as a result
of changes ordered by Entrust or Force Majeure or with Entrust's agreement. The
budget shall provide an allowance for contingencies equal to ten (10%) percent
of all costs, it being understood that all unused allowances and contingencies
in the Tenant Fit-Up budget shall be to the credit of Entrust.

reflecting
<PAGE>

                                       15


activities in the Tenant Fit-Up design and procurement phases. The sub-schedules
shall incorporate the time frames described in the Development Schedule and
shall provide further detail pertaining to the Developer's design activities and
Entrust input, review and approval dates. In the sub-schedules, the Developer
also shall illustrate in detail procurement activity, including, without
limitation, long-term delivery items, tender packages, tender processes, tender
analysis, tender recommendation and contract award. In all cases, the Developer
shall immediately notify Entrust in writing if and when the Developer forecasts
that the Tenant Fit-Up will or may cause a delay in the Substantial Performance
Date or the Commencement Date.

4.6  Procurement
     -----------

The Developer shall issue all Tenant Fit-Up work for tender and shall obtain no
less than three (3) competitive quotations for all Tenant Fit-Up work, subject
to Entrust's written agreement to accept less than three (3) quotations. The
Developer shall provide to Entrust copies of the approved tender packages to be
issued for tender, all correspondence during the tender period and all tender
submissions. The Developer shall provide its review and analysis of all tender
submissions and shall make a recommendation for contract award to Entrust. Upon
receipt of Entrust's approval and instructions, the Developer shall award the
Tenant Fit-Up contract(s) (which award the Developer agrees Entrust may direct
to a tendering party which may not have been the lowest bidder). If the
quotations received as a result of tendering exceed the most recent budget cost
estimates which have been prepared by the Developer and accepted by Entrust
reflecting the then current accepted design status of the Tenant Fit-Up and if
required by Entrust, the Developer shall arrange to re-design and re-tender as
required to ensure that .costs are within the project budget for the Tenant Fit-
Up, the cost of such re-design and re-tender to be borne by the Developer if it
was negligent in the performance of its obligations hereunder, and otherwise to
be borne by Entrust. In all respects, the Developer shall clearly differentiate
between Base Building Core & Shell work and Tenant Fit-Up work and shall use
commercially reasonable efforts to ensure compatibility and coordination between
them.

Notwithstanding anything to the contrary in this subsection 4.6:

(a)  wherever Tenant Fit-Up mechanical and electrical work interfaces with Base
     Building Core & Shell mechanical and electrical systems and any warranty
     for the Base Building Core & Shell mechanical or electrical system may be
     affected if the work is performed by another person, the Base Building Core
     & Shell mechanical and electrical subcontractor must be used; and

(b)  if Entrust fails to provide information in a timely manner to allow the
     Developer to obtain competitive pricing, then the Developer may require
     unit pricing.

4.7  Construction
     ------------

(a)  All changes and additions to building systems to be located in the ceiling
     space, including, but not limited to, lighting, sprinklers, life support
     systems, HVAC diffusers, electrical distribution systems and ceiling grid
     and tiles, that are part of the Tenant Fit-Up are subject to approval by
     Entrust.  It is understood that the Developer shall be
<PAGE>

                                       16


     responsible to install, at its cost, the Base Building Core & Shell
     building systems in the ceiling spaces with due regard to the Tenant Fit-Up
     requirements, so long as:

     (i)   Entrust adheres to the Development Schedule;

     (ii)  the Tenant Fit-Up item is delivered and capable of being carried out
           within the Development Schedule; and

     (iii) Entrust gives all necessary information requested by the Developer
           before the installation of those building systems as part of the
           construction of the Base Building Core & Shell.

It is also understood that the Tenant shall pay for the incremental costs
associated with the Tenant Fit-Up as it impacts the Base Building Core & Shell
ceiling systems. If, however, the Developer installs the Base Building Core &
Shell ceiling systems without due regard to the Tenant Fit-Up requirements, and
Entrust has complied with its obligations set out in the Development Schedule,
then the costs of relocating the Base Building Core & Shell ceiling systems
shall be borne by the Developer. If Entrust does not give all necessary
information requested by the Developer in accordance with the Development
Schedule before the installation of those building systems as part of the
construction of the Base Building Core & Shell or if Entrust requests any
additions to those building systems, then any changes to those systems resulting
from the Tenant Fit-Up and all additions to those building systems are at
Entrust's cost and, if applicable, the Substantial Performance Date may be
extended for Entrust Delay.

(b)  All wall coverings that are part of the Tenant Fit-Up and all floor
     coverings that are part of the Base Building Core & Shell (except for those
     parts of the Base Building Core & Shell which are usually regarded as
     common areas in multi-tenant office buildings, such as lobbies and
     washrooms) are subject to approval by Entrust. The Developer agrees to
     consult with Entrust with respect to floor coverings for those parts of the
     Base Building Core & Shell which are usually regarded as common areas in
     multi-tenant office buildings.

(c)  Subject to subsection 7.1, the Developer shall take all necessary
     precautions to protect the Tenant Fit-Up work at Entrust's expense during
     construction and acknowledges that it is responsible for all damages caused
     by the Developer or those for whom the Developer is in law responsible
     prior to Substantial Performance of the Premises and turnover to Entrust.

(d)  Subject to subsection 3.4, at Entrust's request the Developer shall in good
     faith consider changes to the Base Building Core & Shell so as to satisfy
     Entrust's requirements for the Tenant Fit-Up, provided that Entrust adheres
     to the Development Schedule and gives all necessary information required by
     the Developer in a timely manner to enable the Developer to make the
     requested changes, if the Developer deems them feasible.

review, acceptance, authorization, initialing or approval by Entrust of the
design, construction, commissioning or development of the Premises, in whole or

supplier of the Developer or of a related corporation of the Developer. If the
Developer, any agent of the Developer, the Owner or the Owner's Mortgagee is
made a party to any litigation commenced against Entrust (for liabilities
covered by Entrust's indemnity as specified above) and if Entrust, at its
expense, fails to provide the Developer, its agent, the Owner or the Owner's
Mortgagee with counsel approved by the Developer, its agent, the Owner or the
Owner's Mortgagee, as applicable (which approval shall not be unreasonably
withheld), then Entrust shall pay all costs and reasonable legal fees and
expenses incurred or paid by the Developer, its agent, the Owner or the Owner's
Mortgagee in connection with that litigation. Notwithstanding anything contained
in this Development Agreement to the contrary, Entrust has no liability
whatsoever for consequential, special, exemplary or punitive damages of the
Developer under this Development Agreement or to the Owner under the Lease
Agreement, provided that: (i) the Owner is not precluded from collecting rent
under the Lease Agreement as a result of the deemed commencement of the Lease
Agreement notwithstanding Entrust Delay and (ii) if the Owner is unable to draw
funds from the Owner's Mortgagee on the funding date for the Owner's take-out
financing for the Building as a result of Entrust Delay, Entrust's failure to
execute any subordination agreement or certificate required by the Owner's
Mortgagee, the terms of which have been agreed to by Entrust, within three (3)
business days of receipt of it or otherwise due to the fault of Entrust, then
Entrust shall be liable for and shall indemnify and save harmless the Owner or
Developer as the case may be from any consequential costs and expenses incurred
by it (including, without limitation, all costs and expenses incurred to the
Owner's Mortgagee).

7.2  The Developer's Indemnity
     -------------------------

Save for those matters for which Entrust is to give its indemnity pursuant to
the provisions of subsection 7.1, the Developer and Owner assume liability for
and shall protect, defend and indemnify Entrust, Entrust's officers, directors,
employees and agents and their respective successors and assigns against and
hold them harmless for all liabilities, losses, damages, costs, expense
(including reasonable legal fees and expenses), claims, demands or judgments of
any nature as follows (including claims by third parties):

(a)  relating to any provincial, federal, municipal or other sales, use, excise
     or other taxes due and payable by the Developer;

(b)  actually arising from or in connection with the construction, condition,
     maintenance, or use of the Premises during the period prior to the
     Commencement Date;

(c)  relating to the Premises and the appurtenances to them and the use of them
     by the Developer or anyone claiming by, through or under the Developer
     which may arise with respect to this Development Agreement; and

(d)  arising from or in connection with any of the following events during the
     period prior to the Commencement Date:

     (i)  any injury to or the death of any person arising out of or directly
          connected with the ownership, use, non-use, operation, possession,
          condition, construction, repair or rebuilding of the Premises or
          adjoining property, sidewalks, streets or ways or
<PAGE>

                                       20


           resulting from the condition of any of them during the period prior
           to the Commencement Date;

     (ii)  any claims by third parties to the extent proximately resulting from:
           (A) any actual violation by the Developer of any provision of this
           Development Agreement; (B) any legal requirement affecting the
           Premises during the period prior to the Commencement Date; (C) any
           agreement relating to the Premises to which the Developer is a party
           or by which the Developer is bound; (D) any contract or agreement to
           which the Developer is a party; or (E) any restriction, law,
           ordinance or regulation affecting the Premises or the ownership, use,
           non-use, condition, construction, repair or rebuilding of them or of
           adjoining property, sidewalks, streets or ways; or

     (iii) the Developer's failure to pay in accordance with the provisions of
           this Development Agreement any sums payable by the Developer under
           it.

The Developer is not liable in any case to any indemnified party for any
liabilities, obligations, claims, damages, penalties, causes of action, costs or
expenses to the extent that they result from the negligence or misconduct of the
indemnified party or the negligence or willful misconduct of Entrust or its
subsidiaries. The foregoing shall not be construed to give rise to any third
party beneficiary rights with respect to any person or entity who is not an
indemnified party. If Entrust or any agent of Entrust is made a party to any
litigation commenced against the Developer and if the Developer, at its expense,
fails to provide Entrust or its agent with counsel approved by Entrust or its
agent, as applicable (which approval shall not be unreasonably withheld), then
the Developer shall pay all costs and reasonable legal fees and expenses
incurred or paid by Entrust or its agent in connection with that litigation. The
Developer has no liability to Entrust for any consequential, special, punitive
or exemplary damages under this Development Agreement or the Lease Agreement.

                                      TIME
                                      ----

Time is of the essence with respect to this Development Agreement, subject to
Force Majeure Delay and Entrust Delay.

                                   SECTION 11
                                   ----------
                            RISK OF LOSS OF PREMISES
                            ------------------------

(a)  If at any time or from time to time prior to Substantial Performance of the
     Premises any proceedings are contemplated, commenced or consummated for the
     taking of the Building, the Exterior Building Amenities or a material
     portion of either of them for public or quasi-public use which materially
     affect Entrust's use and enjoyment of the Premises, then the Developer
     shall forthwith give notice to Entrust. That notice shall, if possible, be
     accompanied by a sketch of the portion of the Building or Exterior Building
     Amenities which is affected by the taking and a metes and bounds
     description delineating the area affected. If any taking of the Building,
     the Exterior Building Amenities or any material portion of either of them
     for public or quasi-public use prevents the Developer from complying with
     its obligations under this Development Agreement such that this Development
     Agreement is frustrated in law, then either party may elect to terminate
     this Development Agreement by written notice to the other party given no
     later that thirty (30) calendar days from the date of the notice of taking.
     If this Development Agreement is terminated as aforesaid, then Entrust will
     cooperate with the Developer to attempt to maximize any and all awards and
     other compensation for any such taking. Entrust may make a separate claim
     to the taking authority for Entrust's expenses including, without
     limitation, its expenses related to Tenant's Work to the extent incurred.

(b)  Until Substantial Performance of the Premises, the risk of loss or damage
     to the Premises (but not the Tenant's Work) by fire or otherwise is the
     Developer's. In the event of any fire or other insured damage: (i) the
     Developer shall forthwith give written notice of it to Entrust; (ii) a
     Force Majeure Delay shall be deemed to have occurred; and (iii) the
     Developer shall complete the Premises in accordance with the terms of this
     Development Agreement. The Developer's notice shall specify the extent of
     the damage and the
<PAGE>

                                       23


     estimated time to repair the damage. If the Premises are materially damaged
     by an occurrence against which the Developer is not insured or required to
     be insured under this Development Agreement or beyond the extent to which
     the Developer is required to insure under this Development Agreement and if
     the cost to repair such uninsured damage would exceed $1,000,000 as
     determined by the Developer, acting reasonably, then the Developer may
     elect, in its discretion, to terminate this Development Agreement or to
     complete the Premises in accordance with the terms of this Development
     Agreement (in which event a Force Majeure Delay shall be deemed to have
     occurred), subject to the requirements of the Owner's Mortgagee.

12.1  Differences between the parties as to the interpretation, application or
administration of this Development Agreement shall be submitted to arbitration
pursuant and subject to the Arbitration Act 1991 by one arbitrator. The
arbitrator shall be selected by the parties within ten (10) days after the
giving of written notice by either party to the other that the matter or
disagreement is to be submitted to arbitration, and failing agreement within
that ten (10) day period either party may apply to a Judge of the Superior
Court, Eastern Ontario District for the purpose of having that Judge appoint the
arbitrator. The expense of the arbitration shall be borne equally between the
parties, subject to the jurisdiction of the arbitrator, in his or her
discretion, to award the costs of the arbitration to either party. Any award by
the arbitrator under this subsection is final and binding and is not subject to
appeal.

12.2  The arbitration of any dispute under subsection 12.1 shall not affect the
obligation of 'the Developer to comply with the Development Schedule or the
Substantial Performance Date (subject to extension for Force Majeure Delay or
Entrust Delay) and, as part of the arbitration, the arbitrator shall determine
the proportion of the costs which each party shall bear of any work or other
requirement in dispute performed by the Developer in order to comply with its
obligations under this subsection.

           of such a competitor (as in the Canada Business Corporations Act,
           R.S.C. 1985, as such Act is constituted as at the date of execution
           of this Agreement); and

     (iv)  Canderel Management Inc. continues to be the party which carries out
           the Developer's obligations hereunder,

<PAGE>

                                                                               3

          (iii) Operating Expenses (as defined in the Main Lease) with respect

          The Rent shall be payable by the Tenant to the Landlord in and by way
          of even, equal, consecutive monthly installments each on the first

          prorated.

USE OF THE RESERVED PREMISES

7.   The Reserved Premises are to be used only for recreational purposes, and
then only in conjunction with the Tenant's use of the Main Premises. The Tenant
agrees that:

     (a)  the Landlord shall be permitted to construct from time to time parking
          areas within the Phase 2 Lands (which parking areas are to be used
          solely by the occupants from time to time of the Main Premises);

     (b)  the Landlord shall be permitted to locate therein such services and
          grant such easements therein as the Landlord may require from time to

          portions of the subdivision within which the Main Premises and the
          Expansion Lands are located.

     The Tenant shall not be permitted to carry out any improvements to the
     Reserved Premises without the prior written approval by the Landlord of the
     Tenant's plans and specifications (the plans so approved to be herein
     referred to as "the Approved Plans and Specifications") as well as the
     consent of the Landlord. The Landlord agrees that it will not unreasonably
     withhold its consent to an improvement so long as:

                (a) the Tenant abides by the provisions of any site development
                or subdivision agreement applicable to the Reserved Premises in
                terms of carrying out such improvement, including, without
                limitation, any such provision dealing with the preservation of
                natural landscaping and vegetation;

                (b) the improvement does not include any permanent structure;

                (c) any and all permits required from any governmental authority
                having jurisdiction with respect to the Reserved Premises have
                been obtained by the Tenant at its expense; and

                (d) the implementation of the improvement has been carried out
                in accordance with the Approved Plans and Specifications; and

                (e) the Tenant agrees to restore the Reserved Premises at its
                expense at the end of the Term to the condition they were in
                prior to the improvement being carried out. Notwithstanding the
                foregoing, any restoration with respect to Additional Premises
                (as hereinafter defined) shall be dealt with in the lease or
                other agreement relating to the construction of the Additional
                Premises.
<PAGE>

                                                                               4

     In any other event the Landlord's consent may be unreasonably withheld.

COVENANT TO PAY RENT

8.   The Tenant covenants with the Landlord to pay Rent.

ASSIGNMENT

9.   The Tenant will not assign this Lease or sub-let the whole or any part of
the Reserved Premises without consent, which consent may be unreasonably
withheld and/or delayed. This Lease shall be deemed to have been assigned with
consent to a permitted assignee of the Main Lease. The Tenant hereby waives and
renounces the benefit of any present or future act of the Legislature of Ontario
which would allow the Tenant to assign this Lease or sub-let the Reserved
Premises without consent of the Landlord.

RISKS OF INJURY

10.  The Tenant agrees that the Tenant shall indemnify and save harmless the
Landlord for any accident, injury (including death) or damage whatsoever or
howsoever caused to any person or persons (including the Tenant, its employees,
agents and invitees, any subtenant or licensee of the Tenant and all other
persons claiming through or under any of them) or to the property of any such
person or persons occurring during the Term, caused by want of repair to or by
the use or occupation of the Reserved Premises (the foregoing to be restricted
to matters against which the Tenant is not insured nor obliged to be insured
pursuant to this Lease). Notwithstanding the foregoing, the Landlord agrees that
in the event that any such injury or damage is caused by the acts or omissions
of the Landlord or those for whom the Landlord is in law responsible, the Tenant
shall not be bound to indemnify and save harmless the Landlord for same (with
the Landlord agreeing to indemnify and save harmless the Tenant with respect to
any such matter).

INSURANCE

11.  During the Term, the Tenant shall at its expense maintain in force
comprehensive general liability insurance against claims for personal injury,
death or property damage arising out of all of its operations at the Reserved
Premises in an amount of no less than Five Million Dollars ($5,000,000.00) per
occurrence. The Landlord, the Landlord's mortgagees and the Tenant shall be
named as an additional insured in respect of the insurance policy. The Landlord
shall on request being made by the Tenant provide the Tenant with proof of the
said insurance coverage.

FURTHER LEASING OF THE RESERVED PREMISES

12.  In the event that the Tenant wishes to cause the Landlord to construct any
improvements in the nature of a building within the Reserved Premises for the
Tenant's use (such improvements to be referred to herein as "Additional
Premises"), the Tenant shall give written notice thereof to the Landlord
("Tenant's Notice"). The Landlord and the Tenant agree that unless mutually
agreed to as part of the negotiations detailed below, any such building shall be
constructed on the Phase 2 Lands, and the North Expansion Lands will be used for
such building's associated parking and landscaping. The Landlord and the Tenant
shall negotiate in good faith within the ninety (90) day period next following
the receipt by the Landlord of the
<PAGE>

                                                                               5

Tenant's Notice as to the location, configuration and area of the Reserved
Premises upon which the Additional Premises are to be erected, the area of the
Additional Premises, and all matters as may be necessary for the parties to
achieve agreement in respect of the construction of the Additional Premises and
the terms and conditions of a further lease to be entered into with respect to
the Additional Premises ("the Additional Lease") including term, rental rate and
such other matters as the parties may deem appropriate; provided, however, that
in such negotiations the parties agree that the location, size and configuration
of the Additional Premises must be in conformity with a plan to be developed by
the Landlord with respect to the development of the Reserved Premises; without
limiting or restricting the generality of the foregoing, the location,
configuration and size of the land comprising the Additional Premises must not
compromise the marketability of the remaining portion of the Reserved Premises
(should the Additional Lease not be for the whole of the Reserved Premises), the
Additional Premises must be of such style and design and composed of such
materials such that the Additional Premises and the Building (as defined in the
Main Lease) and any other buildings erected pursuant to the provisions hereof
shall appear to form part of a single integrated project. In the event that the
parties cannot achieve agreement in respect of any of the foregoing matters
within the ninety (90) day delay, notwithstanding their good faith efforts, then
both Landlord and Tenant shall be relieved of any further obligation to
negotiate further in respect of the subject matter of the Tenant's Notice.

DEFAULT

13.  In any of the events following, namely:

     (a)  if the Tenant shall fail to pay the Landlord any installment of Rent
          or any other amount payable hereunder after it shall have become due
          and payable as herein provided so long as the Landlord has notified
          the Tenant in writing of its default and the Tenant has not rectified
          the said default within ten (10) days of being notified of same;

     (b)  if the Tenant or Guarantor shall be declared dissolved, bankrupt or
          wound-up or shall make any general assignment for the benefit of its
          creditors or take or attempt to take the benefit of any insolvency,
          winding-up or bankruptcy legislation or if a petition in bankruptcy or
          in winding-up or for reorganization shall be filed by or granted
          against the Tenant or Guarantor or if a receiver or trustee be
          appointed for or enter into physical possession of the property of the
          Guarantor, or any part thereof;

     (c)  if the Tenant shall assign, sublet or permit the use of the Premises
          by others without the consent of the Landlord (which consent is to be
          provided or withheld in accordance with section 9 of this Lease);

     (d)  if the Tenant is in default of the Main Lease (or, in the event that
          the Main Lease contains a period within which the Tenant is able to
          cure a default, such period expires without the default being cured);

     (e)  if the Tenant shall default in the performance of any of its other
          obligations under this Lease so long as the Landlord has notified the
          Tenant in writing of its default
<PAGE>

                                                                               6

          and the Tenant has not rectified the said default within fifteen (15)
          days of being notified of same (or such longer period of time as is
          necessary for the Tenant to remedy such default (provided the Tenant
          promptly commences and thereafter continues diligently to remedy such
          default)),

     this Lease may be terminated at the option of the Landlord without further
     notice to the Tenant to such effect. It is expressly agreed that such right
     of termination shall be in addition and without prejudice to all other
     rights as provided by law or herein, and the Landlord may re-enter the
     Reserved Premises to have again, repossess and enjoy, as of its former
     estate, anything herein contained to the contrary notwithstanding and
     re-let the Reserved Premises to whomsoever it may choose without further
     notice or demand being necessary and may recover from the Tenant all
     amounts due hereunder at the date of such termination, and Rent for the
     three (3) months next succeeding the date of such termination or such
     longer period as may be allowed by law, all of which shall immediately
     become due and payable. Thereafter the Tenant shall pay to the Landlord, as
     liquidated damages until the end of the Term, an amount equivalent to the
     rental provided in this Lease, less the sum of the net receipts (if any)
     derived by the Landlord from the re-letting of the Reserved Premises. Any
     sums received by the Landlord from or for the account of the Tenant when
     the Tenant is in default hereunder may be applied, at the Landlord's
     option, to the satisfaction in whole or in part of any obligation of the
     Tenant then due hereunder in such manner as the Landlord sees fit and
     regardless of any imputation by law or any designation or instruction of
     the Tenant to the contrary. The Landlord agrees that so long as any default
     by the Tenant is rectified within the time period hereinbefore provided,
     the default shall be deemed to have not occurred.

                                  -----------

3.01 This lease shall terminate without notice or demand therefor being
necessary on the Termination Date (subject to the Tenant exercising an option to
extend the Term pursuant to the provisions of Section 3 of Schedule "F" of this
lease). Should the Tenant remain in occupation of the Premises after the

as one who has not removed at the end of the Term and the Landlord shall be
entitled to all remedies against the Tenant provided by law in that situation,
or the Landlord may elect, at its option, to construe such holding over as a
tenancy from month to month subject to all the terms and conditions of this
lease save as to its duration and save that the Rent payable pursuant to Section

other person as may be specified from time to time by Landlord without any
demand therefor being necessary, without set-off, reduction, deduction or
compensation whatsoever, save as otherwise specifically set out in this lease.

complete and entire exoneration as well as Real Estate Taxes, Tax on Capital and
Operating Expenses as hereinafter set forth and any taxes imposed thereon and on
the Rent.

(except for Tax on Capital to the extent herein mentioned) and Tenant shall not

6.04 Landlord shall have no obligation to contest, appeal, object to or litigate
the levying or imposition of Real Estate Taxes in respect of the Premises and/or
any valuation imposed with respect thereto. Except during the last eleven months
of the Term (and provided that a right to extend the Term as set out in Section
3 of Schedule "F" of this lease has not been exercised) the Landlord shall in
all cases consult with the Tenant prior to the undertaking of any of the
foregoing actions. The Tenant, at its own cost, shall itself have the right to
contest, appeal, object to or litigate the levying or imposition of Real Estate
Taxes and if necessary, in the name of the Landlord, provided the Tenant
received the prior written consent of the Landlord, which consent shall not be
unreasonably withheld or delayed. If required, the Landlord shall provide all
reasonable assistance to the Tenant in respect of such contestation. During the
last eleven months of the Term (and provided that a right to extend the Term as
set out in Section 3 of Schedule "F" of this lease has not been exercised) the
Landlord may settle, compromise, consent to, waive or otherwise determine in its
sole discretion all matters and things relating thereto and the Tenant shall not

6.06 On or before the Commencement Date Landlord shall estimate the amount of
Operating Expenses and Tax on Capital for the then current Lease Year and shall
invoice Tenant for same in equal consecutive monthly installments which Tenant

one hundred and twenty (120) days of the end of each Lease Year, Landlord shall
furnish Tenant with a statement audited by an independent firm of chartered
accountants setting forth the actual Operating Expenses and Tax on Capital for
such year. If such amount is greater or less than the payments on account
thereof made by Tenant pursuant hereto, appropriate adjustments shall be made
forthwith. Thereafter, Tenant shall continue to make the aforementioned monthly
installments on account of estimated Operating Expenses and Tax on Capital for
the ensuing Lease Year on the same basis or on the basis of Landlord's revised
reasonable estimate of same, as the case may be, and so on from time to time.
Landlord shall provide, with such estimate, a reasonably detailed explanation of
the increase in the components of Operating Expenses. The Landlord agrees that
the Tenant shall have the right, at its expense, to inspect and audit the
Landlord's books and records (which inspection may include the taking of copies
of any relevant information, data or invoices in that regard) in respect of any
amount payable by the Tenant with respect to Operating Expenses, Real Estate
Taxes, Tax on Capital and utilities consumed within the Premises for a period of
two (2) years from the date on which the Landlord furnishes the Tenant with the
Landlord's audited statement.

its rights provided herein.

purpose. Nothing herein shall be so interpreted as to imply that this lease is
conditional upon the Tenant obtaining any permits or licenses for the
exploitation of such business from any municipal, provincial or other authority,
and the Landlord makes no warranty with respect to the ability of the Tenant to
carry out the Permitted Uses within the Premises.

additional rent within ten (10) days of the Tenant's receipt of an invoice for
same, the amount so paid.

11.01 The Tenant shall not assign this lease or sublet the Premises or any part
thereof or allow the Premises or any part thereof to be used by another without
the prior written consent of the Landlord, which consent shall not be
unreasonably withheld. The Landlord's refusal of consent shall be deemed
reasonable (without in any way restricting the Landlord's right to refuse its
consent on other reasonable grounds) where the prospective assignee or subtenant
is a consulate, embassy, trade commission or other representative of a foreign
government, where the Premises are intended to be used as medical or dental
offices or facilities, government or quasi-government offices, where the
proposed assignee or subtenant does not intend to bona fide physically occupy
and carry on business from the Premises, when the proposed assignment or
sublease is made prior to the Tenant commencing to physically and bona fide
occupy and carry on business from the Premises or where it is reasonably
anticipated by the Landlord that the number of persons visiting the Premises
will substantially increase as a result of the assignment or subletting.

its other rights), the Landlord shall have the right to cancel the lease for the
Premises (or, as the case may be, for that portion thereof that Tenant seeks to

Landlord under this lease with respect to the Premises (or, as the case may be,

the date Tenant wishes to assign this lease or sublet the Premises or permit
their use by another. Landlord shall exercise the rights herein granted by
sending notice thereof to Tenant within thirty (30) days following receipt of
the notice referred to in Section 11.04 hereof.

11.03 Notwithstanding any assignment, subletting or permitted use by another,
the Tenant shall remain jointly and severally responsible with the assignee,
sublessee or user (and in the circumstances contemplated in Section 11.05
hereof, with the party who acquires control), without benefit of division or
discussion, for the payment of the Rent and all additional rentals and for the
performance of all other obligations of the Tenant under this lease. The Rent
payable by the Tenant shall be increased by an amount equal to the profit, if
any, derived by Tenant from the sublease, assignment or transfer. For all
purposes hereof, "profit" shall mean any benefit given, or the rent, additional
rent and other amounts payable directly or indirectly by the subtenant,
transferee or assignee to or for the account of the Tenant in excess of the Rent
and additional rentals payable by Tenant hereunder including but not limited to
all capital or other sums paid for improvements or otherwise. Landlord shall
have the right to require the subtenant, transferee or assignee to pay its rent
directly to the Landlord.

11.04 Tenant agrees to provide Landlord with at least thirty (30) days' prior
written notice of its intention to assign this lease or sublet the Premises, and
the name, address and nature of business of the proposed assignee or sublessee,
such credit references and other information as Landlord may reasonably request
and copies of the executed assignment or sublease agreement which must be
conditional upon Tenant obtaining the Landlord's consent as hereinabove
provided. Landlord may, at its option, require that as a condition of giving its
consent to an assignment or subletting, Tenant and the proposed assignee or sub
lessee sign a form of assignment or sublet document (in form and content
satisfactory to Landlord). Further, all out-of-pocket costs, charges and
expenses incurred by Landlord in respect of such assignment or sublet document,
as well as a reasonable administrative fee shall be payable as a condition of
the giving of Landlord's consent.

11.05 In the event that the Tenant is an incorporated entity, if at any time
effective control of the Tenant is acquired or exercised by any person or
persons not having effective control of the Tenant on the date of execution of
this lease, the same shall be deemed to constitute a sublease to the party
acquiring such control subject to all of the provisions hereof. This provision
shall not apply to Entrust Technologies Limited.

11.06 The Tenant will not advertise the Premises for the purpose of any sublease
or assignment without obtaining the prior written approval of the Landlord to
the proposed text, such approval not to be unreasonably withheld. In no event
will the rental rate appear or be referred to in any such advertisements.

11.07 Without derogating from the provisions of Section 11.03 hereof, the Tenant
shall not be required to obtain the consent of the Landlord to an assignment or
sublease to an affiliated body corporate or a subsidiary body corporate (as such
expressions are defined in the Canada Business

the said assignment must include an assignment to the proposed assignee of a
certain lease entered into between 786473 Ontario Limited, the Tenant and

13.01 The Tenant shall maintain and keep the Premises, including all
replacements, alterations, additions and improvements thereto, in good order and
condition, reasonable wear and tear which does not render the Premises
untenantable, damage by fire and other insured perils excepted, and shall, in
accordance with the procedures set forth in Section XIV hereof, perform or cause

13.04 In the event Tenant fails to comply with the obligation to maintain,

of twenty (20) days to the Tenant (unless such default cannot reasonably be
remedied within such twenty (20) day period in which case unless the Tenant has
failed to commence to remedy to prosecute with due diligence the curing of such
default until it is remedied), shall have the right (but shall not be obligated)
to carry out such maintenance, repairs and replacements and any and all costs
incurred by the Landlord in so doing, together with a fee equal to ten per cent
(10%) of such costs, shall be payable by the Tenant to Landlord as additional

                ALTERATIONS, ADDITIONS, IMPROVEMENTS AND REPAIRS

14.01 All improvements in and to the Premises other than the improvements which
are the Landlord's responsibility to carry out pursuant to the Development
Agreement (including the Tenant Fit-Up) and other than those which the Landlord
elects to carry out as set out in Section 14.02 of this lease and other than the
Tenant Fit-Up (which the Landlord is to carry out in accordance with the
provisions of this lease and the Development Agreement), shall be the
responsibility of Tenant and shall be performed at Tenant's sole cost and
expense, the whole subject to the terms and conditions set forth in this Section
XIV.

All architectural plans and specifications setting forth Tenant's work may be
prepared by a designer and/or architect of the Tenant's choice but shall be
subject to Landlord's prior written approval as herein mentioned. Said plans and
specifications shall include, without limitation, complete working drawings and
specifications, floor plans, interior elevations, interior finishing schedules,
special facilities or installations that affect the Premises and/or Tenant's
perimeter walls, mechanical, plumbing, sprinklers, telephone and electrical work
(including all fixtures, equipment and under floor services where applicable)
and static and dynamic loading of floors. The Tenant plans and specifications
shall be drawn to the same scale as the base Building working drawings. Tenant
shall be responsible to ensure that the Tenant work, as designed, complies with
all relevant laws, by-laws and regulations as well as with the Building module
and structure and with the Building's mechanical, electrical, plumbing and other
systems. Complete working drawings and specifications shall be submitted:

(a)   with respect to work to be carried out on or about the Commencement Date,
      to the Landlord within twenty-one (21) days following execution of this
      lease or within such other delay as the Landlord and Tenant have otherwise
      agreed; and

(b)   in any other event no later than thirty (30) days prior to the date on
      which the work is to be carried out.

Within ten (10) days following receipt of the complete working drawings and
specifications, Landlord shall notify Tenant either of its approval thereof or
of changes required and if Landlord notifies Tenant that changes are required,
Tenant shall, within seven (7) days thereafter, submit the necessary amended
plans and specifications. Failure by Tenant to submit complete working drawings
and specifications or final plans and specifications within the delays herein
contemplated shall be deemed to be a delay in the completion of the Premises
attributable to Tenant's fault.

14.02 Any and all leasehold improvements and installations to the licenses
required by the Tenant may, at the option of Landlord, be carried out by the
Landlord or under the latter's coordination, in which event the Tenant shall pay
for the costs thereof as well as an amount equal to:
<PAGE>

                                     -14-


(a)   with respect to the Tenant Fit-up, those fees set out in Section 6 of
      Schedule "F" of this lease; and

(b)   with respect to any other leasehold improvements and installations, ten
      percent (10%) of such cost on account of Landlord's overhead and
      administration.

The Landlord agrees that with respect to such leasehold improvements and
installations:

(a)   the Landlord shall issue all such work for tender and shall obtain no less
      than three (3) competitive quotations for all such work, subject to the
      Tenant's written agreement to accept less than three (3) quotations;

(b)   the Landlord shall provide to the Tenant copies of the approved tender
      packages to be issued for tender, all correspondence during the tender
      period and all tender submissions;

(c)   the Landlord shall provide its review and analysis of all tender
      submissions and shall make a recommendation for contract award to the
      Tenant; and

(d)   upon receipt of the Tenant approval and instructions, the Landlord shall
      award the contracts for the said work (which award the Landlord agrees
      that the Tenant may direct to a tendering party which may not have been
      the lowest bidder).

In addition, the Tenant shall pay for the cost of all architectural, engineering
and/or working drawings prepared to comply with the Tenant's requirements and
for the cost of inputting such working drawings in any of the Premises'
computerized design records that may from time to time be maintained as well as
the foregoing fees calculated on the cost thereof. Payment shall be effected by
way of a cash deposit and progress draws during the course of the work, the
specifics of which shall be established by the Landlord, acting reasonably, from
time to time.

14.03 If the applicable work is carried out by the Tenant, the Tenant shall be
required to comply with all applicable laws and regulations with respect to
carrying out same and without limiting the generality of the foregoing, the
Tenant shall not itself make any such improvements, alterations, additions or
repairs to the Premises without obtaining all necessary permits from the
appropriate public authorities and without the prior written consent of the
Landlord pursuant to Section 14.01 hereof. The Tenant shall be required to
submit to the Landlord plans and specifications (in accordance with the
provisions of Section 14.01 hereof and within the delays therein mentioned) for
all such improvements, alterations, additions or repairs and Tenant shall pay
for the cost of inputting such plans and specifications in any Building
computerized design records that may from time to time be maintained. All such
work shall be done by contractors approved by the Landlord, which approval shall
not be unreasonably withheld. All such work shall be conditional upon such
contractors paying the cost of temporary services and coordination during such
construction, upon such contractors timing and performing their work in
accordance with such rules and regulations as the Landlord may from time to time
prescribe, upon such contractors carrying property damage and liability
insurance satisfactory to the Landlord for its operations in the Building and
upon the employees of such contractors not causing any labour trouble by their
presence in the Building. Furthermore, the Tenant shall require that prior to
entering the Premises or performing any work therein, the Tenant's contractors
shall deliver to the Landlord a waiver and release from all lien rights that may
then or
<PAGE>

                                     -15-

thereafter exist for work done, labour performed or materials furnished under
any contract and such contractors must agree to furnish to the Landlord a good
and sufficient waiver of lien rights for every subcontractor and supplier
furnishing labour and material under the contract. In the event that any lien is
registered in respect of any interest in the Lands as a result of any such work,
the Tenant shall forthwith attend to the removal of such lien, failing such
removal within fifteen (15) days the Landlord may, in the name of the Tenant,
and in addition to any other remedies available to the Landlord, be entitled to
attend to the removal of such lien by payment into Court at the cost of the
Tenant (including any expenses and legal fees incurred by the Landlord in
effecting such removal). The Tenant shall be responsible for any costs and
expenses of the Landlord occasioned directly or indirectly by such work in the
Premises as well as the Landlord's reasonable costs and fees for the supervision
and co-ordination of the Tenant's work. The cost of such improvements,
alterations, additions or repairs shall be the sole responsibility of the Tenant
and if any payment in respect thereof shall be made by the Landlord, the
Landlord hereby reserving the right to do so in its sole discretion, the same
shall be immediately payable by the Tenant within ten (10) days of receipt of an
invoice therefor as additional rent. The Tenant shall furthermore pay to the
Landlord as additional rent within ten (10) days of receipt of an invoice
therefor an amount equal to ten percent (10%) of the total cost of all such
work, representing the Landlord's fee for administration and co-ordination of
same.

14.04 All improvements, alterations, additions or repairs to the Premises
(including the Tenant Fit-Up) shall, upon their completion, become part of the
Premises and the property of the Landlord, and, subject as hereinafter provided,
shall be surrendered with the Premises upon termination of the lease without any
compensation being due therefor. Notwithstanding the foregoing, the Tenant may
elect that any or all installations made or installed by or on behalf of the
Tenant (other than Tenant Fit-Up, with the exception of (i) roof-top satellite
dishes, transmission devices and other roof-top devices; and (ii) equipment,
including cafeteria equipment, other than mechanical or electrical equipment) be
removed and if the Tenant so elects then it shall be Tenant's obligation to
restore the Premises to the condition they were in before the installation of
such alterations, installation, partitions and/or fixtures. Without limiting
Tenant's repair and maintenance obligations otherwise set out in this lease, or
the Tenant's obligation to reinstate in accordance with the preceding paragraph,
and subject to the payment obligation set out below, the Tenant shall have no
obligation to remove or reinstate any part of the Building on the Termination
Date (as may be extended in accordance with the provisions of this lease). The
Landlord may elect to require the Tenant to pay for:

(a)   the removal of those items which have been noted by "*" in Section 14 of
      Schedule "F" of this lease;

(b)   the removal of internal staircases (excluding staircases installed as part
      of the Base Building Core & Shell in accordance with applicable laws) and
      the reinstatement of the floor in such areas to base building (smooth,
      trowelled concrete) condition;

(c)   with respect to the cafeteria, the capping of all utility services which
      had serviced the area (including the capping of any exhaust or other
      specialty venting) within such cafeteria area; and
<PAGE>

                                     -16-

(d)   the removal of any or all special, non-standard mechanical or electrical
      equipment or systems, ceilings, and specialty rooms installed after the
      Commencement Date (except that in respect of cables, whether installed
      prior to or after the Commencement Date, the only obligation of the Tenant
      will be to cap or sever such cables, not to pull or remove).

The obligation of the Tenant to pay for the removal and reinstatement of the
applicable items set out above (which for the sake of clarity, does not include
standard building staircases or cables) shall only be to the extent that the
said item is not re-usable by the Landlord. Such re-usability and the quantum of
contribution in respect thereof shall be established by negotiation and based
upon reasonable estimates and allocations provided by an engineer, architect or
quantity surveyor independent of and acceptable to the parties. Failing
agreement on such basis, the quantum of contribution shall be determined by
arbitration in accordance with the provisions of this lease. The Landlord agrees
that it shall obtain three cost estimates with respect to carrying out the
applicable work and the lowest cost estimate so obtained shall be used by the
Landlord for the purposes of invoicing the Tenant with respect to same.

15.01 Should the Landlord effect improvements, alterations, additions,
maintenance, improvements or repairs to the Premises, the Tenant shall permit
same to be performed without being entitled to any indemnity or reduction in
rental or any damages or compensation therefor so long as the Tenant's use and
enjoyment of the Premises are not materially adversely affected (with the
intention that if the Tenant's use and enjoyment of the Premises are materially
adversely affected, and all additional rentals payable hereunder shall abate,
and then only to the extent and for such period of time that the Tenant's use
and occupancy of the Premises are thereby materially adversely affected (Rent to
be calculated at the rate set out in Section 1.01(q) of this lease, subject to
such rate having been varied pursuant to Section 2 of Schedule "F" of this
Lease). All such work shall be completed by the Landlord with reasonable
dispatch and the cost thereof shall be included in Operating Expenses unless
such work is otherwise Landlord's responsibility hereunder.

emergency) to examine their condition and to view their state of repair,
maintain, clean, re-lamp or otherwise and Tenant covenants to repair according

requirements, to persons interested in acquiring the Premises or advancing money

provided that a right to extend the Term as set out in Section 3 of Schedule "F"

18.01 The Landlord and the Tenant will not do or permit anything to be done in,
upon or about the Premises or bring or keep anything therein which will in any
way conflict with the regulations of the fire, police or health departments or
with the rules, regulations, by-laws or ordinances of the municipality in which
the Premises are situate, or any governmental authority having jurisdiction over
the Premises or the business conducted therein, all of which the Landlord and
the Tenant undertake to abide by and conform to.

The Landlord and the Tenant will indemnify and hold harmless the other, their

the company or companies insuring the Premises may exact in consequence of the
business carried on by the Tenant, of anything brought into or stored in the
Premises by the Tenant, or of the Tenant's operations.

may make any insurance carried by the Landlord subject to cancellation.

18.03 The Tenant shall comply with the requirements of all insurance companies
having policies of any kind whatsoever in effect covering the Premises of which
the Tenant has been given notice. The Landlord represents that as of the date of
execution of this lease it has not received notice from any such insurance
company of any such requirement based upon the proposed use of the Premises as
disclosed by the Tenant to the Landlord. In addition, in the event that the
Landlord receives any such notice from any such insurance company of any such
requirement prior to the Commencement Date, the Landlord shall promptly notify
the Tenant of same. In no event shall any inflammable materials or explosives

employees, agents or contractors and then only in respect of matters against
which the Tenant is not insured nor obliged to be insured pursuant to this
lease, the Tenant shall indemnify and hold harmless the Landlord from and
against all claims, liabilities or payments relating to the use and occupancy of
the Premises and, without limiting the generality of the foregoing, Tenant does
hereby agree to indemnify and hold harmless the Landlord from and against all
claims, liabilities, damages, costs, suits or actions arising from:

      agents and invitees, any subtenant or licensee of the Tenant and all other
      persons claiming through or under any of them) or to the property of any
      such person or persons occurring during the Term, caused by want of repair
      (other than want of repair occurring as a result of inherent structural
      defects in the Building), or by the use or occupation of the Premises;

      agreement set forth in the present lease on the part of Tenant to be
      fulfilled, kept, observed or performed;

      not done, in or about the Premises by the Tenant, its agents, employees or

      its agents, employees or contractors; and

(d)   the failure of the Tenant to fully, faithfully and punctually comply with
      all of the legitimate requirements of any public or quasi-public authority
      having jurisdiction over the Premises.

18.05 Notwithstanding any express or implicit obligation on the part of Landlord
to insure and further notwithstanding any obligation on the part of Tenant to
contribute to the payment of Landlord's premiums, Tenant acknowledges that
Tenant shall remain responsible for its negligence and those of all persons for
whom it is in law responsible, that no insurable interest is conferred upon the
Tenant under any of Landlord's insurance policies and that Tenant shall have no
right to recover any proceeds thereunder or claim any right or title to such
proceeds.

is insured or obliged to be insured pursuant to this lease (in which case the
following indemnity is not to apply), the Landlord shall indemnify and hold
harmless the Tenant from:

(a)   any accident, injury (including death) or damage whatsoever or howsoever
      caused to any person or persons or to the property of any such person or
      persons occurring during the Term, caused by want of repair occurring as a
      result of inherent structural defects in the Building;

      does not so elect to terminate this lease, the Landlord shall diligently
      proceed to repair the Building; and

(d)   If the Building is, as a result of any such occurrence, rendered unusable
      in whole or in part for the purpose of the Tenant's use and occupancy
      thereof, the Rent and all additional rentals payable hereunder shall abate
      only to the extent and for such period of time that the Tenant's use and
      occupancy of the Premises is thereby diminished (Rent to

                                     -20-

      be calculated at the rate set out in Section 1.01(q) of this lease,
      subject to such rate having been varied pursuant to Section 2 of Schedule
      "F" of this lease) from the date of such occurrence, only to the extent
      that the Landlord is able to draw upon the rental insurance which it is
      obliged to keep in force hereunder until Landlord's repair obligations
      have been completed.

The Landlord agrees to make reasonable efforts having regard to the nature and
extent of the loss, to notify the Tenant of the said architect's opinion within
a shorter period of time.

20.02 Notwithstanding the foregoing, Landlord shall not be required to restore
or rebuild the Building under any circumstances in the event less than two (2)
years remain in the Term from the date of occurrence of the damage or
destruction.

20.03 In the event Landlord elects to restore or rebuild as aforesaid, it is
expressly understood and agreed that the extent of Landlord's obligation will be
to rebuild or restore to substantially the condition in which the Premises were
initially delivered to Tenant (which for clarity is to include the Tenant
Fit-Up) subject to existing by-laws and other modifications as Landlord and
Tenant, acting reasonably, shall mutually agree upon. Nothing herein contained
shall be construed to oblige the Landlord to repair or reconstruct any
alterations, improvements or property of the Tenant. On the contrary, all other
improvements in and to the Premises shall be the responsibility of Tenant who
shall be obliged to repair and re-fixture to a standard at least equivalent to
that which existed prior to the date of damage and destruction.

destruction arising in or upon the Premises to any property or person nor for
any personal injuries sustained by the Tenant, its officers, servants,
employees, agents, invitees or licensees, which may result at any time from any
reason or cause whatsoever, the Tenant hereby covenanting to indemnify the
Landlord of and from all loss, costs, claims or demands in respect of such
damage, loss, injury or destruction. Without limiting the generality of the
foregoing, the Landlord shall not under any circumstances (other than as set out
above) be liable for any damage resulting from water, steam, rain or snow which
may leak into, issue or flow from the pipes or plumbing or sprinklers or from
any other part of the Building or from any other place or quarter. No event or
occurrence herein contemplated shall be deemed an eviction or disturbance of the
Tenant's enjoyment of the Premises nor render the Landlord liable in damages to

other amount payable hereunder.

21.02 Subject to the provisions of the Development Agreement, Landlord shall not
be liable for failure to perform any of its obligations hereunder nor be

third parties, fuel shortages, Acts of God or of the Queen's enemies, fire or
other casualty, force majeure, cas fortuit, or any other cause beyond the
Landlord's reasonable control and Landlord shall not be responsible for any acts

parties. No such occurrence or event shall be deemed an eviction or disturbance
of the Tenant's enjoyment of the Premises nor render the Landlord liable in

other amounts payable hereunder, but in any such event the Landlord shall
without delay take all reasonable steps to remove the cause of such
interruption.

With the exception of monetary obligations of the Tenant pursuant to this lease,
the Tenant shall not be liable for failure to perform any of its obligations
hereunder caused or required by strikes, riots, labour controversies, accidents,
fault or delays caused by Landlord or third parties, the shortages, Acts of God
or of the Queen's enemies, fire or other casualty, force majeure, cas fortuit,
or any other cause beyond the Tenant's reasonable control. No such occurrence or
event shall render the Tenant liable in damages to the Landlord, but in any such
event the Tenant shall without delay take all reasonable steps to remove the
cause of such interruption.

21.03 Save and except for the fault or negligence of the Landlord, or those for
whom the Landlord is in law responsible, and then only in respect of matters
against which the Tenant is not insured nor obliged to be insured pursuant to
this lease, without limiting the generality of the foregoing, the Landlord shall
not be liable for any damage of any kind or nature to the Premises or to any
goods, merchandise, stock-in-trade, assets, fixtures, furniture, accessories or
equipment belonging to the Tenant or to the Tenant's officers, servants,
employees, agents, invitees or licensees resulting from robbery, burglary, theft
or acts of violence of any kind, and the Tenant will hold the Landlord free,
clear and harmless from any liability or loss resulting therefrom.

                                   ---------

22.01 Throughout the Term and any renewal thereof, Tenant shall take out and
keep in force:

(a)   comprehensive general liability insurance (including blanket contractual
      liability coverage) with respect to the business carried on in or from the
      Premises and the use and occupancy thereof on an occurrence basis for
      bodily injury and death and damage to property of others in an amount of
      at least five million dollars ($5,000,000.00) for each occurrence as well
      as automobile liability insurance including contractual liability covering
      all licensed vehicles operated by or on behalf of the Tenant;

(b)   all-risks insurance including the perils of fire, extended coverage,

      improvements located within the Premises and such other property located
      in or forming part of the Premises, including all mechanical or electrical
      systems (or portions thereof) installed by Tenant in the Premises, the
      whole for the full replacement cost (without depreciation) in each such
      instance;
<PAGE>

                                     -22-

(c)   tenants' legal liability insurance in an amount equal to the replacement
      cost of the Premises; and

      with industry standards, may from time to time require.

22.02 All policies of insurance shall be placed with insurers to which the
Landlord has no reasonable objection, and provide that they will not be
cancelled or permitted to lapse unless the insurer notifies Landlord in writing
at least thirty (30) days prior to the date of cancellation or lapse. Each such
policy shall name Landlord and any other party required by Landlord, including
but not limited to its property manager and mortgagees, as an additional
insured(s) as its (or their) interest(s) may appear. The Tenant's insurance
policies and coverages shall be primary. Each liability policy will contain a
provision of cross-liability and severability of interests as between Landlord
and Tenant. All other policies referred to above shall contain a waiver of
subrogation rights which Tenant's insurers may have against Landlord, Landlord's
insurers and persons under Landlord's care and control. Notwithstanding anything
contained in this lease to the contrary, Tenant hereby releases and waives any
and all claims against Landlord and those for whom Landlord is in law
responsible with respect to occurrences which are or which are required to be
insured against by Tenant hereunder. Tenant shall from time to time furnish
Landlord with certificates of all such insurance policies and the renewals
thereof.

22.03 Should Tenant fail to take out or keep in force such insurance, Landlord,
subject to a ten (10) day written notification (or such shorter period of time
as the Landlord is given by its insurer to cure the default) to the Tenant
(unless the default is cured within the aforesaid period) will have the right to
do so and to pay the premiums therefor and in such event Tenant shall repay to
Landlord the amount paid as premiums as additional rental on demand.

      days of being notified of same;

(b)   if the Tenant or Guarantor shall be declared dissolved, bankrupt or

      possession of the property of the Tenant, or any part thereof;

(c)   if the Tenant shall assign, sublet or permit the use of the Premises by
      others except in a manner herein permitted so long as the Landlord has

      brought into or stored in the Premises by the Tenant so long as the
      Landlord has notified the Tenant in writing of its default and the Tenant
      has not rectified the said default within fifteen (15) days' of being
      notified of same; or

(f)   if the Tenant shall default in the performance of any of its other
      obligations under this lease including, without limitation, the obligation
      to pay business taxes in a timely manner, fail to effect any payment that

      default)),

this lease may be terminated at the option of the Landlord without further
notice to the Tenant to such effect. It is expressly agreed that such right of
termination shall be in addition and without prejudice to all other rights as
provided by law or herein, and the Landlord may re-enter the Premises to have
again, repossess and enjoy, as of its former estate, anything herein contained
to the contrary notwithstanding and re-let the Premises to whomsoever it may
choose without further notice or demand being necessary and may recover from the
Tenant all amounts due hereunder at the date of such termination, expenses of
such re-letting (including any repairs, decorating, alterations or improvements
necessitated thereby) and rental for the three (3) months next succeeding the
date of such termination or such longer period as may be allowed by law, all of
which shall immediately become due and payable. Thereafter the Tenant shall pay
to the Landlord, as liquidated damages until the end of the Term, an amount
equivalent to the rental provided in this lease, less the sum of the net
receipts (if any) derived by the Landlord from the re-letting of the Premises.
As used herein, the expression "rental" shall mean the Rent, Real Estate Taxes,
Operating Expenses and Tax on Capital, and all other additional rents payable
hereunder. Any sums received by the Landlord from or for the account of the
Tenant when the Tenant is in default hereunder may be applied, at the Landlord's
option, to the satisfaction in whole or in part of any obligation of the Tenant
then due hereunder in such manner as the Landlord sees fit and regardless of any
imputation by law or any designation or instruction of the Tenant to the
contrary. The Landlord agrees that so long as any default by the Tenant is
rectified within the time period hereinbefore provided, the default shall be
deemed to have not occurred.

with the Tenant, to make minor changes, alterations, amendments or expansions to

amendments which are in the Premises are minor in nature and do not materially
affect the Tenant's use and enjoyment of the Premises). The Tenant waives and

such change results in additional land being utilized to service the Premises,
such additional land shall be deemed included in the definition of "Land" for

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

1.    CERTIFICATE AS TO THE AREA OF THE BUILDING

The Landlord agrees that the gross building area of the Building shall be
measured prior to the Commencement Date in accordance with ANSI/BOMA "Standard
Method for Measuring Gross Building Area in Office Building" - Single Tenant
Occupancy (Z65.1-1996) at the Landlord's cost by a professional land surveyor or
architect. The Landlord and the Tenant agree that with respect to the basement
level of the Building ("the Basement"), Rent for the Basement shall be
calculated based on the area of the Basement being the lesser of the actual
measured area of the Basement or five thousand (5,000) square feet.

2.    ADJUSTMENT TO THE RENT

The Landlord and the Tenant agree that if modifications (any such modification
to be referred to in this Schedule as a "Modification") in the Preliminary Plans
and Specification, the Progress Drawings and Specification, the Site Plan and
the Tenant Fit-Up Plans and Specifications (all as defined in the Development
Agreement) ordered by the Tenant are consented to by the Landlord and decrease
or increase the total cost of the Base Building Core & Shell, the Rent payable
by the Tenant to the Landlord in each month of the Term shall be decreased or
increased by an amount equal to:

(a)   where the Modification has a useful life beyond the Term and is of value
      to a potential future tenant, $0.08l per square foot per annum for each
      $100,000.00 of cost of the Modification; and

(b)   in any other event, $0.103 per square foot per annum for each $100,000.00
      of cost of the Modification,

all pro-rated to take into consideration the actual cost of the Modification.
The Tenant agrees that the Landlord shall not be required to consent to a
Modification only if:

(A)   the Landlord is unable to obtain funds from the is mortgagee with respect
      to carrying out the modification); or

(B)   the Landlord reasonably determines that the Modification is not beneficial
      to the Premises on a long-term basis; or

(C)   Rent is increased beyond what is deemed by the Landlord, acting
      reasonably, to be an acceptable market rent for premises which are similar
      to and in the vicinity of the Premises.

3.    OPTION TO EXTEND THE TERM

Provided the Tenant is not then in material default at the time of the exercise
of the applicable option in respect of any of the terms and conditions of this
lease beyond any cure period herein
<PAGE>

                                     -38-

provided and provided the Tenant remains in occupation of all of the Premises
(or if the Tenant has exercised any of its rights to cancel this lease with
respect to portions of the Premises as provided for in Section 8 of Schedule "F"
of this lease, the Premises as defined after such cancellation(s)), the Tenant
shall have two (2) consecutive options to extend the Term for the entirety of
the Premises for periods of five (5) years each upon the same terms and
conditions as set out in this lease, save and except that:

(a)   there shall not be any tenant allowances or inducements (subject to what
      is hereinafter set out with respect to establishing Market Rate) or any of
      the rights contained in Section 8 of this Schedule "F");

(b)   there shall be no further options to renew the lease or to extend the
      Term; and

(c)   the Rent shall be the "Market Rate".


To exercise the foregoing option, the Tenant shall provide written notice
thereof to the Landlord no less than twelve (12) months prior to the expiration
of the initial Term or first extension of the Term, as the case may be, in
default whereof the first option and, if applicable, the second option shall be
deemed null and void and of no further legal effect.

For the purposes of this lease, the expression "Market Rate" means the net
rental rate per square foot for comparable space in other buildings in the area
of comparable quality, considering the size of the premises, the quality of the
tenant covenant and the tenant inducements being offered at the time for five
(5) year leases including but not limited to cash and leasehold improvement
allowances and free rent periods, and taking into account applicable brokerage
commissions. The Landlord and the Tenant agree to use their best efforts to
agree on the Market Rate. In the event that they do not so agree upon the Market
Rate for the extended Term nine (9) months prior to the Termination Date, Market
Rate shall be established by the arbitration of a single arbitrator appointed
pursuant to and governed by the provisions of the Arbitrations Act of Ontario
(as such legislation is constituted as at the date of execution of this lease).

4.    MANAGEMENT OF THE BUILDING

The Landlord shall manage the Premises (at the expense of the Tenant, as part of
Operating Expenses) including the provision of landscaping services, snow
removal and maintenance of the exterior of the Building, and excluding security
services for the Premises (which the Tenant shall manage directly) as a prudent
and reasonable owner, in keeping with standard industry practice for first class
office buildings. In the event that the Tenant, acting reasonably, is
dissatisfied with the cost, standard or quality of the delivery of services to
be co-ordinated and administered by the Landlord for the Premises, the Tenant
may request that the Landlord replace the provider of the service and the
Landlord shall use its best efforts to comply with such request.

5.    MAINTENANCE OF THE BUILDING

The Landlord agrees that, subject to the Tenant's obligations set out in this
lease, the Landlord shall maintain the Premises in a first-class condition, in a
good state of repair, and in compliance with applicable laws and the Tenant
agrees that the cost of same shall be included in Operating
<PAGE>

                                     -39-

Expenses (except as otherwise provided for in this lease). Except to the extent
the Tenant is responsible therefor under this lease, the Landlord shall comply
with all laws, by-laws, codes, regulations or ordinances in respect of the
operation, maintenance and condition of the Premises.

6.    LEASEHOLD IMPROVEMENT ALLOWANCE/TENANT FIT-UP

The parties hereto agree that the Tenant Fit-Up shall be carried out by the
Landlord to the Premises at the Tenant's expense and shall be completed, subject
to the provisions of the Development Agreement, on or about the Commencement
Date. The Landlord agrees to contribute an allowance ("the Allowance") towards
the cost of the Tenant Fit- Up, as provided for in Section 4.1(c) of the
Development Agreement. The Allowance shall be paid and applied as against the
cost of the Tenant Fit-Up and in accordance with the provisions of the
Development Agreement.

faxes, photocopies, long distance telephone charges) of the Landlord, the
following fee shall be payable by the Tenant within respect to the construction
cost component of the Tenant Fit-Up:

      attached hereto) relating to the Tenant Fit-Up per square foot of gross
      building area of the Building; and

(b)   five percent (5%) with respect to the balance of the Cost of the Work
      relating to the Tenant Fit-Up.

Notwithstanding the foregoing, the fee payable with respect to the Generator (as
hereinafter defined) shall be five percent (5%) of its installation costs (with
no fee applicable to the cost of the Generator itself). No fee shall be payable
with respect to:

      (i)   permits, design or general expenses applicable to the Tenant Fit-Up;

      (ii)  any landscaping or hardscaping costs that the Tenant may be
            responsible to pay for in excess of the $ 175,000.00 allowance
            provided for pursuant to the provisions of Section 3.14 of the
            Development Agreement; or

      (iii) any Tenant's Work (as defined in the Development Agreement).

There shall be no fee (or out-of pocket disbursements) applicable to any design,
consulting, architectural or engineering work relating to, nor in respect of the
construction of, the Base Building Core & Shell or Exterior Building Amenities,
unless same are impacted by the Tenant Fit-Up.

(c)   the Building and equipment therein will not contain any formaldehyde foam
      insulation, asbestos or polychlorinated biphenyls;

(d)   the heating, air-conditioning and ventilating systems, electrical and

      the Tenant as outlined and agreed to in the Project Definition Binder (as
      defined in the Development Agreement); and

(e)   it will be the registered owner of the Land or, in the event that title to
      the Land is not in the name of the Landlord as at such date, the Landlord
      will cause the registered owner of the Land to sign this lease on or
      before the Commencement Date.

8. TENANT'S RIGHT TO SURRENDER ITS INTEREST IN PORTIONS OF THE PREMISES

The Tenant is hereby granted an option ("the First Cancellation Option") to
cancel this lease with respect to one whole floor of the Building on November 1,
2005 and a further option ("the Second Cancellation Option") to cancel this
lease with respect to one whole floor of the Building on November 1, 2007 (the
applicable date to be referred to herein as "the Early Termination Date"). In
order to exercise either such option, the Tenant agrees to give to the Landlord
written notice ("the Surrender Notice") of its intention to do so no later than
nine (9) months prior to the applicable Early Termination Date. The Tenant shall
pay a termination payment to the Landlord on the applicable Early Termination

into consideration the rentable area of the floor which is the subject of the
Surrender Notice), together with an amount equal to Rent, Operating Expenses,
Realty Taxes, Tax on Capital and utilities for a period of three (3) months (as
if the Building had been fully occupied) for such floor, all together with
applicable taxes on such amounts.

      detailed in Section 2(b) of this Schedule "F", to the portion of the
      unamortized balance applicable to the end of the initial Term),

      are to be for the common use and enjoyment of all tenants of the
      Building); and

(c)   the area of the Premises after any cancellation shall be calculated as
      being the area of the Building as at the Commencement Date (as increased,
      if applicable in the event that further areas of the Building are
      constructed for the Tenant after the Commencement Date) less the area of
      the premises which is the subject of a Surrender Notice (or Surrender
      Notices, as the case may be), which area is to be measured at the Tenant's
      expense in accordance with the ANSI/BOMA "Standard Method for Measuring
      Basic Rentable Area in Office Building" (Z65.l-1996).

16.   LANDLORD'S COVENANTS

(a)   The Landlord covenants with the Tenant for quiet enjoyment and covenants
      to act reasonably and as a prudent owner in exercising all rights and so
      as not to interfere more than is reasonably necessary under the
      circumstances with the Tenant's use and enjoyment of the Premises.

(b)   The Landlord shall, throughout the Term of this lease or any renewal
      thereof, maintain the following insurance at the Tenant's cost:

      (i)   Insurance in respect of such perils as are from time to time covered
            in an "all risks" policy not less broad than the standard commercial
            property floater policy with the exclusions relating to earthquake
            and flood removed therefrom for the replacement cost of the Building
            and its equipment and Landlord's leasehold improvements forming part
            of the Premises (such replacement cost to be determined by Landlord
            acting reasonably upon consultation with Landlord's insurance
            consultants). In addition, this insurance will cover the interest of
            the Tenant, if any, in the leasehold improvements. Subsequent
            increases in such replacement cost shall be determined in the
            reasonable opinion of the Landlord from time to time. However, if
            despite the Landlord's best efforts "all risk" coverage is not
            available at reasonable cost, the Landlord shall obtain the most
            comprehensive coverage available;

      (ii)  Rental insurance in an amount equal to the aggregate of twelve (12)
            months Rent, Real Estate Taxes, Operating Expenses, Tax on Capital,
            utility charges and other amounts payable hereunder;

      (iii) Broad boiler, machinery and unfired pressure vessel, and electrical
            equipment insurance, including repair or replacement coverages in an
            amount mutually agreeable to the Landlord and Tenant or, failing
            such agreement, as established by an appraiser mutually agreeable to
            the Landlord and Tenant and paid for by the Tenant but at no time
            less than as required by any mortgagee of the Building; and

      (iv)  General liability insurance with respect to bodily injury and
            property damage suffered by third parties and arising out of risks
            associated only with the ownership of the Premises in an amount of
            at least five million dollars ($5,000,000.00) for each occurrence or
            such greater amount as the Landlord, may from time to time
            reasonably require.
<PAGE>

                                     -45-

(c)   All insurance policies, where applicable, shall include a waiver of
      subrogation in favour of the Tenant, the Tenant's insurers and those for
      whom the Tenant is in law responsible (whether or not the loss or damage
      is caused by their acts or omissions) and each liability policy shall in
      addition contain a provision for cross-liability and severability of
      interest.

17.   GENERATOR

One or more generators will be installed within the Premises as part of the
Tenant Fit-Up which includes its (or their) associated engine(s), alternator and
alternator control panel, battery and charger system (i.e. what is generally
referred to as the "Uninteruptable Power Supply" or "UPS"), cooling system,
exhaust system, fuel pump and day tank (all of the said items to be collectively
referred to as "the Generator") together with its associated exterior enclosure,
concrete pad and all structural supports and screening, main fuel tank and fuel
delivery system outside the said enclosure, subsystems within the enclosure
(such as, but not limited to power panel, lighting, heating, and monitoring
equipment), automatic transfer switch, and all feeder conductors from the
generator into the Building. The Tenant acknowledges that the Landlord will be
connecting the Building's life safety system ("the LSS") to the Generator and
that such connection shall continue throughout the Term. For clarity, the Tenant
agrees that such connection shall continue in the event that the Tenant has
exercised any of its rights to cancel this lease with respect to portions of the
Premises as provided for in Section 8 of Schedule "F" of this lease. Without
limiting any of the Tenant's obligations under this lease, the Tenant agrees
that it shall maintain the Generator in good order and condition at its expense
throughout the Term. Notwithstanding the foregoing, the testing and maintenance
of the LSS, including such portion of the Generator relating to the LSS, shall
be carried out by the Landlord in accordance with any building codes applicable
thereto. The said testing and maintenance shall be at such intervals as would be
carried out by a prudent owner of a building similar to the Building and the
cost thereof will be included in Operating Expenses.

In consideration of the Tenant permitting the LSS to be connected to the
Generator the Landlord agrees to contribute the sum of $85,000.00 ("the
Generator Allowance") to the acquisition price of the Generator. The Generator
Allowance shall be credited to the Tenant's rental account on the day that is
the later of thirty (30) days after the Commencement Date and the date on which
the LSS is connected to the Generator.

At the end of the Term (as extended, if applicable), the Tenant agrees that the
Landlord shall have the option to purchase the Generator ("the Generator
Purchase Option") upon payment to the Tenant of an amount ("the Landlord's
Generator Payment") calculated as being the unamortized balance (based on a
straight-line amortization over twenty (20) years) of the difference between the
Tenant's acquisition cost of the Generator (which cost for clarity is not to
include any cabling or equipment other than the Generator) and the Generator
Allowance. The Generator Purchase Option may be exercised by the Landlord at any
time prior to the last sixty (60) days of the Term (as extended, if applicable)
and in the event that it is so exercised:

(a)   the Landlord's Generator Payment shall be paid to the Tenant within thirty
      (30) days of the Landlord notifying the Tenant that it is exercising the
      Generator Purchase Option;
<PAGE>

                                     -46-

(b)   the Tenant shall execute and deliver to the Landlord at the time that the
      Generator Payment is made to the Tenant:

      (i)   a bill of sale and other documentation reasonably required by the
            Landlord to transfer title to the Generator to the Landlord or its
            nominee free and clear of any encumbrances; and

      (ii)  an assignment of any and all warranties applicable to the Generator,

      in form and content satisfactory to the Landlord, acting reasonably.

In the event that the Landlord does not so exercise the Generator Purchase
Option, the Tenant shall:

(a)   remove the Generator from the Premises and, at the Landlord's option,
      their associated cabling and equipment and other items set out in the
      first paragraph of this Section 17, and restore the Premises to the
      condition they were in before the installation of the Generator, and

(b)   pay to the Landlord the unamortized balance (based on a straight-line
      amortization over twenty (20) years) of the Generator Allowance within
      forty-five (45) days of the last day of the Term.

18.   OPINION RE: GUARANTEE

The Tenant and the Guarantor agree that the Landlord shall be provided with an
opinion (or opinions) in form and content satisfactory to the Landlord, acting
reasonably, from counsel from the Guarantor as to the enforceability of the
guarantee provisions contained in this lease. In the event that such opinion is
not provided to the Landlord within thirty (30) days of execution of this lease,
the Guarantor agrees that it shall be deemed to be named Tenant hereunder until
such time as the Landlord has been provided with the said opinion(s).
