                               PROSPECTUS SUMMARY

     You should read the following summary together with the more detailed
information and BackWeb's consolidated financial statements and the notes to
those statements appearing elsewhere in this prospectus.

                           BACKWEB TECHNOLOGIES LTD.

     We are a leading provider of Internet communication infrastructure software
and application-specific software that enable companies to communicate
business-critical, time-sensitive information throughout their extended
enterprise of customers, partners and employees. Our products provide a reliable
solution for communicating large amounts of data in any digital format by
enabling our customers to automatically gather and disseminate information. Our
products efficiently disseminate this information across a network of any speed
by automatically adapting the rate of transmission to match the available
network capacity, commonly referred to as bandwidth. Our software enables
companies to adapt quickly to changing market conditions through direct
interaction with their customers, partners and employees, thereby accelerating
the execution of their business processes.

     Although we have a limited operating history, industry leaders such as
AT&T, Cisco Systems, Goldman Sachs, Pacific Bell, Rite Aid and Schlumberger have
chosen our products to address a variety of their critical business
communication needs. We intend to pursue additional customers in each of these
industries to expand our customer base.

     Our infrastructure software, BackWeb Foundation, is a platform that allows
organizations to efficiently gather, target and deliver sizeable digital data of
any format to users' desktops across their extended enterprise. Our software
enables management to capture the immediate attention of targeted recipients and
monitor the recipients' level of interaction with the information delivered. We
work with our customers, partners and third-party software vendors to develop
applications built on top of BackWeb Foundation.

     Our infrastructure software platform is powered by three core technologies
that we have developed:
     - Polite Communications, a unique technology that enables the transmission
       of significant volumes of digital data through existing networks without
       interfering with normal network applications and traffic.

     - Attention Management, a technology that uses a variety of display
       techniques to alert desktop users to the delivery of business-critical
       information.

     - Closed Loop Delivery, a technology that allows companies to track, manage
       and survey the effectiveness of communications throughout their extended
       enterprise.

     We have also developed our first packaged application, BackWeb Sales
Accelerator. This application enables organizations to strengthen their customer
relationships by accelerating the response times of the organizations' sales
forces and partners to critical market changes. BackWeb Sales Accelerator
provides a geographically dispersed sales organization with up-to-date
information, such as competitive and customer information from external sources,
internal sales and marketing materials, product pricing information and critical
management announcements.

                                  RISK FACTORS

     This offering involves a high degree of risk. You should carefully consider
the risks described below and the other information in this prospectus before
deciding to invest in the ordinary shares.

 OUR BUSINESS IS DIFFICULT TO EVALUATE BECAUSE OUR OPERATING HISTORY IS LIMITED
                  AND WE RECENTLY CHANGED OUR STRATEGIC FOCUS

     We have a limited operating history and an even more limited history
operating the business as currently conducted. We cannot be certain that our
business strategy will be successful. We were incorporated on August 31, 1995
and did not begin generating revenues until December 1996. In early 1998, we
changed our strategic focus from a consumer-oriented to an enterprise-oriented
Internet communication company. This change required us to adjust our business
processes and make a number of significant personnel changes.

            WE HAVE A HISTORY OF LOSSES AND WE EXPECT FUTURE LOSSES

     We have not achieved profitability and expect to continue to incur net
losses for at least the foreseeable future. We incurred net losses of
approximately $7.7 million for the year ended December 31, 1996, $15.0 million
for the year ended December 31, 1997, and $14.6 million for the year ended
December 31, 1998 and $3.7 million for the three months ended March 31, 1999. As
of March 31, 1999, we had an accumulated deficit of approximately $41.2 million.

     We expect to continue to incur significant sales and marketing, product
development and administrative expenses and expect such expenses to increase in
1999. As a result, we will need to generate significant revenues to achieve and
maintain profitability.

OUR QUARTERLY OPERATING RESULTS ARE SUBJECT TO FLUCTUATIONS AND SEASONALITY AND
  IF WE FAIL TO MEET THE EXPECTATIONS OF SECURITIES ANALYSTS OR INVESTORS, OUR
                     SHARE PRICE MAY DECREASE SIGNIFICANTLY

     Our operating results are difficult to predict. Our future quarterly
operating results may fluctuate significantly and may not meet the expectations
of securities analysts or investors. If this occurs, the price of our ordinary
shares would likely decline. The factors that may cause fluctuations of our
operating results include the following:

     - the size, timing and contractual terms of sales of our products and
       services due to the long and unpredictable sales cycle of our products;

     - delays we may encounter in introducing new versions of BackWeb Foundation
       and BackWeb Sales Accelerator and new products and services;

     - changes in information systems resource allocation by our customers;

     - the mix of products and services sold because our profit margins differ
       among products and services; and

     - the fixed nature of expenses such as base compensation and rent.

     Quarterly revenues and operating results generated by our business
generally depend on license fees from our customers within the quarter. Revenues
from license fees depend upon the volume of end-users. A decrease in end-users
or the cancellation or deferral of any customer contract would reduce our
expected revenues, which could negatively affect our quarterly financial
performance.

     Moreover, our sales may be subject to seasonality or cyclicality. We expect
that revenues in the first quarter of each year may be lower than revenues in
the fourth quarter of the preceding year. We believe this trend may occur as a
result of our customers annual budgetary, purchasing and sales cycles. For
example, the growth rate of our license revenues decreased in the quarter ending
March 31, 1999 compared to the growth rate of our license revenues for the
quarter ended December 31, 1998. For a more detailed description of our
quarterly results, please see "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

                                        4
<PAGE>   9

  WE ANTICIPATE INCREASED OPERATING EXPENSES WHICH COULD CAUSE OUR BUSINESS TO
             SUFFER IF WE DO NOT CORRESPONDINGLY INCREASE REVENUES

     We plan to significantly increase our operating expenses to expand our
sales and marketing operations, broaden our customer support capabilities,
improve operational and financial systems, develop new distribution channels and
fund greater levels of research and development. If we do not significantly
increase our revenues to meet these increased expenses, our business will
suffer.

 OUR BACKWEB FOUNDATION PLATFORM AND APPLICATIONS ARE NEW AND IT IS UNCLEAR IF
                      THEY WILL ACHIEVE MARKET ACCEPTANCE

     We do not know if our products will be successful. The market for Internet
communications solutions is in its infancy, and we are not certain that our
target customers will widely adopt and deploy our technology throughout their
networks. Even if our products are effective, our target customers may not
choose them for technical, cost, support or other reasons.

     Our future growth depends on the commercial success of BackWeb Foundation
and applications developed upon BackWeb Foundation, such as BackWeb Sales
Accelerator, introduced in December 1998.

 OUR SOFTWARE PLATFORM ENABLES THIRD PARTIES TO DEVELOP APPLICATIONS WHICH MAY
                   COMPETE WITH APPLICATIONS DEVELOPED BY US

     Because of BackWeb Foundation's open architecture, third parties have the
ability to develop their own applications on top of our platform. Such third
parties could compete with applications developed by BackWeb. If our target
customers do not widely adopt and purchase our products, or if third parties
were to compete with applications developed by us, our business would suffer.

                        OUR GROWTH MAY SUFFER BECAUSE OF
                        THE DIFFICULTIES IN IMPLEMENTING
                                  OUR PRODUCTS

     The use of our products by our customers requires implementation services.
Although we currently provide implementation services sufficient to meet our
current business level, our growth will be limited in the event we are unable to
expand our implementation services personnel or subcontract these services to
qualified third parties.

 IF WE LOSE A MAJOR CUSTOMER, OUR REVENUES COULD SUFFER BECAUSE OF OUR CUSTOMER
                                 CONCENTRATION

     We have generated a substantial portion of our annual and quarterly
historical revenues from a limited number of customers. As a result, if we lose
a major customer, or if there is a decline in end-users in any of our customers'
licenses, our revenues would be adversely affected. In 1997, revenues from
Computer Associates and CompuServe represented 19% and 11%, respectively, of our
revenues. In 1998, no customer accounted for more than 10% of our revenues. We
expect that a small number of customers will continue to account for a
substantial portion of revenues for the foreseeable future.

 OUR LONG AND UNPREDICTABLE SALES CYCLE DEPENDS ON FACTORS OUTSIDE OUR CONTROL
              AND MAY CAUSE LICENSE REVENUES TO VARY SIGNIFICANTLY

     To date, our customers have taken a long time to evaluate our products
before making their purchase decisions. The long, and often unpredictable, sales
and implementation cycles for our products may cause license revenues and
operating results to vary significantly from period to period. Along with our
distribution partners, we spend a lot of time educating and providing
information to our prospective customers regarding the use and benefits of our
products. In addition, our customers often begin by purchasing our products on a
pilot basis before they decide whether or not to purchase additional licenses
for full deployment. Even after purchase, our customers tend to deploy BackWeb
Foundation slowly, depending upon:

     - the skill set of the customer;

     - the size of the deployment;

     - the complexity of the customer's network environment; and

                                        5
<PAGE>   10

     - the quantity of hardware and the degree of hardware configuration
       necessary to deploy our products.

COMPETITION IN THE INTERNET COMMUNICATIONS MARKET MAY REDUCE THE DEMAND FOR, OR
                            PRICES OF, OUR PRODUCTS

     The Internet communications market is intensely competitive and rapidly
changing. We expect that competition will intensify in the near-term because of
the attention the Internet is currently receiving and because there are very
limited barriers to entry. Our primary long-term competitors may not have
entered the market yet because the Internet communications market is new.
Competition could result in price reductions, fewer customer orders, reduced
gross margin and loss of market share, any of which could cause our business to
suffer. We may not be able to compete successfully, and competitive pressures
may harm our business.

     Many of our current and potential competitors have greater name
recognition, longer operating histories, larger customer bases and significantly
greater financial, technical, marketing, public relations, sales, distribution
and other resources than we do. Some of our potential competitors are among the
largest and most well-capitalized software companies in the world. For
additional discussion of our competition, please see "Business -- Competition."

 FAILURE TO EXPAND OUR SALES AND MARKETING ORGANIZATIONS COULD LIMIT OUR GROWTH

     If we fail to substantially expand our direct and indirect sales and
marketing operations in our existing markets, our growth will be limited. We
have recently expanded our direct sales force in North America and Europe and
plan to hire additional sales personnel to meet market demand. As of March 31,
1999, we employed approximately 60 individuals in our sales and marketing
organizations. Currently, we believe we will need to expand our sales and
marketing organization by more than fifty percent of its current size over the
next eighteen months, although this increase is dependent on our ability to
increase sales. We might not be able to hire or retain the kind and number of
sales and marketing personnel we are targeting because competition for qualified
sales and marketing personnel in the Internet communications market is intense.

                        FAILURE TO DEVELOP KEY STRATEGIC
                      RELATIONSHIPS COULD LIMIT OUR GROWTH

     We believe that our success in penetrating our target markets depends in
part on our ability to develop and maintain strategic relationships with key
independent software vendors, or ISVs, resellers, systems integrators,
distribution partners and customers. If we fail to develop these strategic
partnerships, our growth could be limited. Although we do not have any current
exclusive strategic relationships, we have recently entered into nonexclusive
agreements with SAP and Baan relating to the distribution of our products. We
have not derived significant revenues from these agreements and we may not be
able to derive significant revenues in the future from these agreements.

          WE MAY EXPERIENCE DIFFICULTIES MANAGING OUR EXPECTED GROWTH

     Our ability to successfully offer products and services and to implement
our business plan in the rapidly evolving Internet communications market
requires an effective planning and management process. We continue to increase
the scope of our operations domestically and internationally and expect to grow
our headcount substantially depending on market conditions. In addition, in
connection with the recent change in our strategy from a consumer-oriented to an
enterprise-oriented Internet communications company, we have reorganized our
sales force.

     These factors have placed, and our anticipated future operations will
continue to place, a significant strain on our management systems and resources.
We expect that we will need to continue to improve our financial and managerial
controls and reporting systems and procedures, and expand, train and manage our
work force worldwide. Furthermore, we expect that we will be required to manage
multiple relationships with various customers and other third parties.

                                        6
<PAGE>   11

                      THE GLOBAL NATURE OF OUR OPERATIONS
                        STRAINS OUR MANAGEMENT RESOURCES

     If we fail to manage our geographically dispersed organization, we may fail
to meet or exceed our business plan and our revenues may decline. Our research
and development facilities are located in Canada and Israel, and our directors,
executive officers and other key employees are similarly dispersed throughout
the world. In addition, we maintain offices in the United States, Canada, Japan
and Europe to market and sell our products in those countries and surrounding
regions. This geographic dispersion requires significant management resources
that our locally-based competitors do not need to devote to their operations. In
addition, the expansion of our existing international operations and entry into
additional international markets will require significant management attention
and financial resources.

  OUR INTELLECTUAL PROPERTY COULD BE USED BY THIRD PARTIES WITHOUT OUR CONSENT
           BECAUSE PROTECTION OF OUR INTELLECTUAL PROPERTY IS LIMITED

     Our success and ability to compete are substantially dependent upon our
internally developed technology, which we protect through a combination of
patent, copyright, trade secret and trademark law. However, we may not be able
to adequately protect our proprietary rights which may harm our business.
Unauthorized parties may attempt to copy or otherwise obtain and use our
products or technology. Policing unauthorized use of our products is difficult,
and we cannot be certain that the steps we have taken will prevent
misappropriation of our technology, particularly in foreign countries where the
laws may not protect our proprietary rights as fully as in the United States.
For a more detailed description of the protection of our intellectual property,
please see "Business -- Intellectual Property and Proprietary Rights."

                         OUR PRODUCTS MAY BE USED IN AN
                         UNINTENDED AND NEGATIVE MANNER

     Our products are used to transmit information through the Internet. Our
products could be used to transmit harmful applications, negative messages,
unauthorized reproduction of copyrighted material, inaccurate data, or computer
viruses to end-users in the course of delivery. Any such transmission could
damage our reputation or could give rise to legal claims against us. We could
spend a significant amount of time and money defending against these legal
claims.

        OUR PROPRIETARY TECHNOLOGY MAY BE SUBJECT TO INFRINGEMENT CLAIMS

     Substantial litigation regarding intellectual property rights exists in the
software industry. A successful claim of product infringement against us and our
failure or inability to license the infringed or similar technology could harm
our business. We expect that software products may be increasingly subject to
third-party infringement claims as the number of competitors in our industry
segments grows and the functionality of products in different industry segments
overlaps. Third parties may make a claim of infringement against us with respect
to our products and technology. Any claims, with or without merit, could:

     - be time-consuming to defend;

     - result in costly litigation;

     - divert management's attention and resources;

     - cause product shipment delays; or

     - require us to enter into royalty or licensing agreements.

     Royalty or licensing agreements, if required, may not be available on
acceptable terms, if at all. For additional information, please see
"Business -- Intellectual Property and Proprietary Rights."

WE DO NOT HAVE SUFFICIENT INSURANCE TO COVER ALL POTENTIAL PRODUCT LIABILITY AND
                                WARRANTY CLAIMS

     Our products are integrated into our customers' networks. The sale and
support of our products may entail the risk of product liability or warranty
claims based on damage to these networks. In addition, the failure of our
products to perform to customer expectations could give rise to warranty claims.

                                        7
<PAGE>   12

Although we carry general liability insurance, our insurance would likely not
cover potential claims of this type or may not be adequate to protect us from
all liability that may be imposed.

   RAPID TECHNOLOGICAL CHANGES COULD CAUSE OUR PRODUCTS TO BECOME OBSOLETE OR
                      REQUIRE US TO REDESIGN OUR PRODUCTS

     The Internet communications market is characterized by rapid technological
change, frequent new product introductions, changes in customer requirements and
evolving industry standards. If we are unable to develop and introduce products
or enhancements in a timely manner to meet these technological changes, we may
not be able to successfully compete. In addition, our products may become
obsolete in which event we may not be a viable business.

       OUR BUSINESS COULD SUFFER IF WE LOSE THE SERVICES OF KEY PERSONNEL

     We will need to hire a significant number of additional sales, support,
marketing, and research and development personnel in calendar 1999 and beyond to
increase our revenues. If we fail to attract qualified personnel or retain
current employees, our revenues may not increase and could decline.

     Competition for these individuals is intense, and we may not be able to
attract, assimilate or retain additional highly qualified personnel in the
future. Our future success also depends upon the continued service of our
executive officers and other key sales, marketing and support personnel. In
addition, our products and technologies are complex and we are substantially
dependent upon the continued service of our existing engineering personnel, and
especially our founders. None of our officers or key employees is bound by an
employment agreement for any specific term. Our relationships with these
officers and key employees are at will. Moreover, we do not have "key person"
life insurance policies covering any of our employees.

 ANY MAJOR DEVELOPMENTS IN THE POLITICAL OR ECONOMIC CONDITIONS IN ISRAEL COULD
  CAUSE OUR BUSINESS TO SUFFER BECAUSE WE ARE INCORPORATED IN ISRAEL AND HAVE
              IMPORTANT FACILITIES AND RESOURCES LOCATED IN ISRAEL

     We are incorporated under the laws of the State of Israel. Our principal
research and development facilities as well as significant executive offices are
located in Israel. Any major hostilities involving Israel or the interruption or
curtailment of trade between Israel and its present trading partners could
significantly harm our business. Since its establishment in 1948, the State of
Israel has been and continues to be in a state of hostility with its neighbors,
varying from time to time in intensity and degree.

     Some of our senior officers and key employees are currently obligated to
perform annual reserve duty in the Israel Defense Forces and are subject to
being called for active military duty at any time. Fulfillment of these
obligations may deprive us of key employees for extended periods of time.

     Inflation in Israel and devaluation of the NIS could have an impact on our
financial results. Although Israel has substantially reduced the rates of
inflation and devaluation in recent years, they are still relatively high
compared to those in the United States and we could be harmed by inflation or
devaluation. If inflation rates in Israel increase again and hurt Israel's
economy as a whole, our operations and financial condition could suffer. For a
more detailed discussion of the political, military and economic environment in
Israel, please see "Conditions in Israel."

  ANY FUTURE PROFITABILITY MAY BE DIMINISHED IF TAX BENEFITS FROM THE STATE OF
                         ISRAEL ARE REDUCED OR WITHHELD

     Pursuant to the Law for the Encouragement of Capital Investments, the
Israeli government has granted "Approved Enterprise" status to our existing
capital investment programs. Consequently, we are eligible for tax benefits for
the first several years in which we generate taxable income. Our future
profitability may be diminished if all or a portion of these tax benefits are
reduced. These tax benefits may be cancelled in the event of

                                        8
<PAGE>   13

changes in Israeli government policies or if we fail to comply with requisite
conditions and criteria. Currently the most significant conditions which we must
continue to meet include making specified investments in fixed assets,
maintaining the development and production nature of our facilities, and
financing of at least 30% of these investments through the issuance of capital
stock. For a more detailed discussion of Israeli tax laws, please see "Israeli
Taxation and Investment Programs."

    OUR GROWTH MAY BE LIMITED IF WE DO NOT DEVELOP LOCALIZED VERSIONS OF OUR
                                    PRODUCTS

     Historically, most of our sales have been in the United States. In order to
expand internationally, we need to develop localized versions of our products.
If we fail to develop these localized versions, our growth prospects would be
limited. We currently have limited experience in developing localized versions
of our products and marketing and distributing our products internationally.

                     EXCHANGE RATE FLUCTUATIONS BETWEEN THE
           U.S. DOLLAR AND THE NIS MAY NEGATIVELY AFFECT OUR EARNINGS

     Although most of our revenues and a majority of our expenses are
denominated in U.S. dollars, a significant portion of our research and
development expenses are incurred in NIS. In addition, we are engaged in certain
loan transactions with affiliates denominated in and dependent on NIS. As a
result, we may be negatively affected by fluctuations in the exchange rate
between the U.S. dollar and the NIS.

                     THE LOSS OF OUR RIGHT TO USE SOFTWARE
            LICENSED TO US BY THIRD PARTIES COULD HARM OUR BUSINESS

     We license technology that is incorporated into our products from third
parties, including security and encryption software. Any interruption in the
supply or support of any licensed software could disrupt our operations and
delay our sales, unless and until we can replace the functionality provided by
this licensed software. Because our products incorporate software developed and
maintained by third parties, we depend on these third parties to deliver and
support reliable products, enhance their current products, develop new products
on a timely and cost-effective basis and respond to emerging industry standards
and other technological changes.

    OUR BUSINESS WILL SUFFER IF OUR TARGET CUSTOMERS DO NOT ACCEPT INTERNET
                                   SOLUTIONS

     Our future revenues and profits, if any, depend upon the widespread
acceptance and use of the Internet as an effective medium of business and
communication by our customers. Rapid growth in the use of and interest in the
Internet has occurred only recently. As a result, acceptance and use may not
continue to develop at historical rates, and a sufficiently broad base of
consumers may not adopt, and continue to use, the Internet and other online
services as a medium of commerce and communication.

     Our success will depend, in large part, on the acceptance of the Internet
in the commercial marketplace and on the ability of third parties to provide a
reliable Internet infrastructure network with the speed, data capacity, security
and hardware necessary for reliable Internet access and services. To the extent
that the Internet continues to experience increased numbers of users, increased
frequency of use or increased bandwidth requirements of users, the Internet
infrastructure may not be able to support the demands placed on it and the
performance or reliability of the Internet could suffer.

  WE MAY OFFER TO REPURCHASE SOME OF OUR PREVIOUSLY GRANTED OPTIONS AND ISSUED
    SHARES AND MAY BE SUBJECT TO PENALTIES UNDER CALIFORNIA SECURITIES LAWS

     We may commence a rescission offer pursuant to the state securities laws of
the State of California because we failed to qualify or receive an exemption
from qualification under California state securities laws when we granted
options to some of our employees in the State of California. The rescission
offer would cover options to purchase ordinary shares issued pursuant to our
1996 U.S. Stock Option Plan and ordinary

                                        9
<PAGE>   14

shares issued upon exercise of these options which were granted to approximately
42 people in California from 1996 to 1998. The rescission offer would allow
these people to return their equity interests in us in exchange for at least
twenty percent of the exercise price per underlying share for each outstanding
option they hold and the price per share paid by each of these people plus seven
percent interest for each share issued upon exercise of these options. If the
rescission offer is consummated in 1999, BackWeb could be required to make an
aggregate payment in an amount which we believe is not material to us and which
we currently believe will be no more than $400,000. As a legal matter, it
remains uncertain whether we have any liability under California state
securities laws since publicly traded companies are exempt from such filings. In
addition, we are not aware of any claims for rescission against us at the time
of this prospectus. Upon completing a rescission offer approved by the
California Department of Corporations the aforementioned optionees should not
have any rescission rights under California law. We may still be subject to
penalties or fines related to these issuances.

    FAILURE OF OUR PRODUCTS OR COMPUTER SYSTEMS OR THOSE OF OUR CUSTOMERS TO
    RECOGNIZE THE YEAR 2000 COULD DISRUPT THE OPERATION OF OUR BUSINESS AND
                               TECHNICAL SYSTEMS

     Many currently installed computer systems and software products are not
capable of distinguishing 21st century dates from 20th century dates. As a
result, beginning on January 1, 2000, computer systems and software used by many
companies and organizations in a wide variety of industries, including
technology, transportation, utilities, finance and telecommunications, will
produce erroneous results or fail unless they have been modified or upgraded to
process date information correctly. In addition, we face the possibility that
our products will fail due to processing errors caused by inaccurate
calculations with respect to the Year 2000.

     Year 2000 compliance efforts may involve significant time and expense, and
uncorrected problems could harm our business. Moreover, we may face claims based
on Year 2000 issues arising from the integration of multiple products within an
overall system. We may also experience reduced sales of our products as
potential customers reduce their budgets for our products due to increased
expenditures on their own Year 2000 compliance efforts. For a further discussion
of Year 2000 issues, see "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Year 2000."

ISRAELI REGULATIONS MAY LIMIT OUR ABILITY TO ENGAGE IN RESEARCH AND DEVELOPMENT
                            AND EXPORT OUR PRODUCTS

     Under Israeli law we are required to obtain an Israeli government license
to engage in research and development of and export of the encryption technology
incorporated in our products. Our current government license to engage in these
activities expires April 4, 2000. Our research and development activities in
Israel and our ability to export our products out of Israel would be limited if:

     - the Israeli government revokes our current license;

     - our current license is not renewed;

     - our license fails to cover the scope of the technology in our products;
       or

     - Israeli law regarding research and development or export of encryption
       technologies were to change.

  WE EXPECT TO EXPERIENCE VOLATILITY IN OUR SHARE PRICE WHICH COULD NEGATIVELY
                             AFFECT YOUR INVESTMENT

     You may not be able to resell your shares at or above the initial public
offering price due to a number of factors, including:

     - announcements of technological innovations;

     - announcements relating to strategic relationships;

     - conditions affecting the Internet industry; and

     - trends related to the fluctuations of stock prices of Israeli companies.

                                       10
<PAGE>   15

     The trading price of our ordinary shares may be volatile. The market for
technology and Internet-related companies, has experienced extreme volatility
that often has been unrelated to the operating performance of particular
companies. These fluctuations may adversely affect the trading price of our
ordinary shares, regardless of our actual operating performance.

ISRAELI COURTS MIGHT NOT ENFORCE JUDGMENTS RENDERED OUTSIDE OF ISRAEL WHICH MAY
         MAKE IT DIFFICULT TO COLLECT ON JUDGMENTS RENDERED AGAINST US

     We are incorporated in Israel. Some of our directors and executive officers
and the Israeli experts named herein are not residents of the United States and
some of their assets and our assets are located outside the United States.
Service of process upon our non-U.S. resident directors and executive officers
or the Israeli experts named herein and enforcement of judgments obtained in the
United States against us, and our directors and executive officers, or the
Israeli experts named herein, may be difficult to obtain within the United
States. BackWeb Technologies, Inc., our U.S. subsidiary, is the U.S. agent
authorized to receive service of process in any action against us in any federal
or state court arising out of this offering or any related purchase or sale of
securities. We have not given consent for this agent to accept service of
process in connection with any other claim.

     We have been informed by our legal counsel in Israel, Naschitz, Brandes &
Co., that there is doubt as to the enforceability of civil liabilities under
U.S. securities laws in original actions instituted in Israel. However, subject
to certain time limitations, an Israeli court may declare a foreign civil
judgment enforceable if it finds that:

     - the judgment was rendered by a court which was, according to the laws of
       the state of the court, competent to render the judgment;

     - the judgment is no longer appealable;

     - the obligation imposed by the judgment is enforceable according to the
       rules relating to the enforceability of judgments in Israel and the
       substance of the judgment is not contrary to public policy; and

     - the judgment is executory in the state in which it was given.

     Even if the above conditions are satisfied, an Israeli court will not
enforce a foreign judgment if it was given in a state whose laws do not provide
for the enforcement of judgments of Israeli courts (subject to exceptional
cases) or if its enforcement is likely to prejudice the sovereignty or security
of the State of Israel. An Israeli court also will not declare a foreign
judgment enforceable if:

     - the judgment was obtained by fraud;

     - there was no due process;

     - the judgment was rendered by a court not competent to render it according
       to the laws of private international law in Israel;

     - the judgment is at variance with another judgment that was given in the
       same matter between the same parties and which is still valid; or

     - at the time the action was brought in the foreign court a suit in the
       same matter and between the same parties was pending before a court or
       tribunal in Israel.

   OUR OFFICERS, DIRECTORS AND AFFILIATED ENTITIES OWN A LARGE PERCENTAGE OF
        BACKWEB AND COULD SIGNIFICANTLY INFLUENCE THE OUTCOME OF ACTIONS

     We anticipate that our executive officers, directors and entities
affiliated with them will, in the aggregate, beneficially own approximately
24.9% of our outstanding ordinary shares following the completion of this
offering. These shareholders, if acting together, would be able to significantly
influence all matters requiring approval by our shareholders, including the
election of directors and the approval of mergers or other business combination
transactions.

    WE HAVE ADOPTED ANTI-TAKEOVER PROVISIONS THAT COULD DELAY OR PREVENT AN
   ACQUISITION OF BACKWEB, EVEN IF AN ACQUISITION WOULD BE BENEFICIAL TO OUR
                                  SHAREHOLDERS

     Provisions of Israeli corporate and tax law and of our Articles of
Association may

                                       11
<PAGE>   16

have the effect of delaying, preventing or making more difficult a merger or
other acquisition of BackWeb, even if doing so would be beneficial to our
shareholders.

     Israeli law regulates mergers, votes required to approve a merger,
acquisition of shares through tender offers and transactions involving
significant shareholders. In addition, our charter documents provide for a
staggered board of directors. For further discussion, please see
"Management -- Election of Directors" and "Description of Share Capital."

VIRTUALLY ALL OF OUR SHARES WILL BE ELIGIBLE FOR SALE SHORTLY AFTER THE OFFERING
    AND SUBSTANTIAL SALES OF OUR SHARES COULD CAUSE OUR SHARE PRICE TO FALL

     If our shareholders sell substantial amounts of our ordinary shares,
including shares issued upon the exercise of outstanding options and warrants,
in the public market following this offering, the market price of our ordinary
shares could fall dramatically. Such sales also might make it more difficult for
us to sell equity or equity-related securities in the future at a time and price
that we deem appropriate.

     Upon completion of this offering, we will have outstanding 32,446,139
ordinary shares, based upon shares outstanding as of March 31, 1999. Of these
shares, the 5,500,000 shares sold in this offering are freely tradable. This
leaves 26,946,139 shares eligible for sale in the public market as follows:

     In addition, upon completion of the offering we will have 2,595,501
ordinary shares that are issuable at any time for no additional consideration
upon exchange of the BackWeb Canada exchangeable shares issued to the former
shareholders of Lanacom, Inc. in connection with our acquisition of Lanacom. We
have agreed to register the resale of these ordinary shares on the 180th day
after the date of this prospectus.

     Moreover, on or prior to the 180th day after the date of this prospectus,
we intend to register for resale approximately 10.9 million ordinary shares
reserved for issuance or issued under our employee stock plans. Please see
"Shares Eligible for Future Sale" and "Underwriting."

      INVESTORS IN OUR ORDINARY SHARES FACE SUBSTANTIAL IMMEDIATE DILUTION

     The initial public offering price is expected to be substantially higher
than the book value per share of our outstanding ordinary shares. As a result,
investors purchasing ordinary shares in this offering will incur immediate
substantial dilution of $7.45 per share. In addition, we have issued options and
warrants to acquire ordinary shares at prices significantly below the initial
public offering price. To the extent such outstanding options are ultimately
exercised, there will be further dilution to investors in this offering.

               SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS

     We have made forward looking statements in this prospectus that are subject
to risks and uncertainties. Forward looking statements include information
concerning possible or assumed future results of operations of BackWeb. Also,
when we use such words as "believes," "expects," "anticipates" or similar
expressions, we are making forward looking statements. You should note that an
investment in our securities involves risks and uncertainties that could affect
future financial results. Our actual results could differ materially from those
anticipated in these forward looking statements as a result of factors,
including those set forth in "Risk Factors" and elsewhere in this prospectus.

                                USE OF PROCEEDS

     We estimate the net proceeds to us from the sale of the 5,500,000 ordinary
shares being offered to be approximately $44.3 million at an assumed public
offering price of $9.00 per share, after deducting the underwriting discount and
estimated offering expenses payable by us, or $51.2 million if the
over-allotment option is exercised in full.

     We intend to use approximately $2.9 million of the net proceeds of the
offering to repay indebtedness, of which $2.0 million bears interest at prime
rate plus 4% per annum, and approximately $900,000 bears no interest. The $2.0
million line of credit matures on December 31, 1999 and the $900,000 loan is
repaid at a rate of 2.5% of cumulative consolidated revenues in excess of $5.0
million. We are currently using the proceeds of this indebtedness for working
capital. We expect to use the balance of the net proceeds from this offering for
general corporate purposes. In addition, we may use a portion of the net
proceeds to acquire complementary products, technologies or businesses. However,
we currently have no commitments or agreements and are not involved in any
negotiations with respect to any such transactions. Pending use of the net
proceeds of this offering, we intend to invest the net proceeds in
interest-bearing, investment-grade securities.

     We are not limited in our use of the proceeds of this offering. We cannot
predict that the investment of the proceeds in our operations and otherwise will
yield a favorable return.

<PAGE>   18

                                DIVIDEND POLICY

     We have never paid cash dividends to our shareholders and we currently do
not intend to pay dividends for the foreseeable future. We intend to reinvest
earnings in the development and expansion of our business. We have decided to
reinvest the amount of tax exempt income derived from our Approved Enterprise
status and not to distribute such income as dividends. See Note 9 of Notes to
the Consolidated Financial Statements included in this prospectus. We may only
pay cash dividends in any fiscal year out of "profits," as determined under
Israeli law. In addition, the terms of financing arrangements restrict us from
paying dividends to our shareholders.

     Because of our investment program's Approved Enterprise status, the payment
of dividends by us may be subject to certain Israeli taxes to which we would not
otherwise be subject to. The tax exempt income attributable to the Approved
Enterprise status can be distributed to shareholders without subjecting us to
taxes only upon our complete liquidation. If we decide to distribute cash
dividends out of income that has been exempt from tax, the income out of which
the dividend is distributed will be subject to Israeli corporate tax.

     In the event we declare dividends in the future, we will declare those
dividends in NIS but pay those dividends to our non-Israeli shareholders in U.S.
dollars. Under current Israeli regulations, any dividends or other distributions
paid in respect of ordinary shares, may be freely repatriated in non-Israeli
currencies at the rate of exchange prevailing at the time of conversion,
provided that Israeli income tax has been paid on or withheld from such
dividends. Because exchange rates between NIS and the dollar fluctuate
continuously, a U.S. shareholder will be subject to currency fluctuation between
the date when the dividends are declared and the date the dividends are paid.
For additional discussion of Israeli tax issues involved in our payment of cash
dividends, please see "Israeli Taxation and Investment Programs."

                                 CAPITALIZATION

     The following table sets forth our capitalization as of March 31, 1999:

     - on an actual basis;

     - on a pro forma basis giving effect to the conversion of all outstanding
       shares of our preferred stock as of March 31, 1999 into 23,090,238
       ordinary shares automatically upon the closing of this offering other
       than the Series E Preferred Stock, which will not be converted
       automatically; and

     - on a pro forma as adjusted basis to reflect conversion of the preferred
       stock and the sale of 5,500,000 ordinary shares by us at an assumed
       public offering price of $9.00 per share and our anticipated application
       of the net proceeds of the offering.

     You should read this information together with BackWeb's consolidated
financial statements and the notes to those statements appearing elsewhere in
this prospectus.

- ---------------
(1) In connection with our acquisition of Lanacom, we issued to the Lanacom
    selling shareholders 8,532,909 exchangeable shares of BackWeb Canada, Inc.,
    a wholly owned subsidiary of BackWeb, and one share of our Series E
    Preferred Stock. The exchangeable shares of BackWeb Canada, Inc. are
    exchangeable for an aggregate of 2,595,501 ordinary shares.

(2) Based on the number of shares actually outstanding on March 31, 1999.
    Excludes:

    - 4,946,980 ordinary shares issuable upon exercise of stock options
      outstanding as of March 31, 1999 at a weighted average exercise price of
      $1.51 per share.

    - 145,726 ordinary shares issuable upon exercise of warrants outstanding as
      of March 31, 1999 at a weighted average exercise price of $3.45 per share.

    - 3,646,344 ordinary shares available for future grant or issuance under our
      various benefit plans as of March 31, 1999.

                                    DILUTION

     Our net tangible book value as of March 31, 1999 was $10.0 million or
approximately $0.34 per share. Net tangible book value per share represents the
amount of our total tangible assets less total liabilities, divided by the
number of ordinary shares outstanding, assuming the issuance of 2,595,501
ordinary shares issuable for no additional consideration upon exchange of
BackWeb Canada exchangeable shares. Dilution in net tangible book value per
share represents the difference between the amount per share paid by purchasers
of ordinary shares in the offering made hereby and the net tangible book value
per ordinary share immediately after the completion of this offering. After
giving effect to the sale of the 5,500,000 ordinary shares offered by us hereby
at an assumed public offering price of $9.00 per share and after deducting the
underwriting discount and estimated offering expenses payable by us, our net
tangible book value at March 31, 1999 would have been approximately $54.3
million, or $1.55 per share. This represents an immediate increase in net
tangible book value of $1.21 per share to existing shareholders and an immediate
dilution in net tangible book value of $7.45 per share to new investors or
ordinary shares in this offering. The following table illustrates this dilution
on a per share basis:

     The foregoing discussion and tables are based upon the number of shares
actually outstanding on March 31, 1999 and assume the issuance of 2,595,501
ordinary shares issuable for no additional consideration upon exchange of
BackWeb Canada exchangeable shares issued in connection with the Lanacom
acquisition and no exercise of options and warrants outstanding as of March 31,
1999. As of March 31, 1999, there were options outstanding to purchase 4,946,980
ordinary shares at a weighted average exercise price of $1.51 per share and
warrants outstanding to purchase 145,726 ordinary shares at a weighted average
exercise price of $3.45 per share. To the extent these options and warrants are
exercised, there will be further dilution to new investors.

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

     Except for historical information, the discussion in this report contains
forward-looking statements that involve risks and uncertainties. These
forward-looking statements include, among others, those statements including the
words, "expects," "anticipates," "intends," "believes" and similar language. Our
actual results could differ materially from those discussed herein. Factors that
could cause or contribute to such differences include, but are not limited to
the risks discussed in the section titled "Risk Factors" in this prospectus.

                                    OVERVIEW

     BackWeb is a leading provider of Internet communication infrastructure
software and application-specific software that enables companies to communicate
business-critical, time-sensitive information to their customers, partners and
employees.

     We were incorporated on August 31, 1995 and commenced our operations in
November 1995. During the period from commencement of operations through
December 31, 1996, we were in a development stage and had insignificant
revenues. Operating activities during this period related primarily to
developing our products, building our corporate infrastructure and raising
capital. In December 1996, we shipped the first commercial version of our
software.

     In August 1997, in an effort to expand the features and functionalities of
our product offerings, we acquired all the outstanding shares of Lanacom Inc., a
Canadian corporation. The acquisition has been accounted for using the purchase
method of accounting, and accordingly the purchase price has been allocated to
the tangible and intangible assets acquired and the liabilities assumed on the
basis of their respective fair value on the acquisition date. The purchase price
of $3.9 million was determined based on the value of shares originally issued
and options granted. Of the total purchase price, approximately $3.2 million was
allocated to goodwill, representing the excess of the aggregate purchase price
on the fair value of tangible and intangible assets. The remainder of the
purchase price was allocated to net tangible liabilities assumed ($103,000),
developed technology ($400,000) and other identifiable intangible assets
($383,000). Goodwill, developed technology and other identified intangibles are
amortized on a straight-line basis over the estimated useful life which range
from 24 to 30 months. The first BackWeb product, Version 4.0, incorporating
Lanacom's Headliner product, was released in January 1998.

     In early 1998, we engaged in a comprehensive reexamination of our business
strategy and changed our strategic focus from a consumer-oriented to an
enterprise-oriented Internet communication company. In connection with this
change in strategy, we undertook a fundamental repositioning and reorganization
of our work force, particularly in our sales organization. During 1998, we
continued to enhance our infrastructure software, BackWeb Foundation Version
5.0, and in December 1998 released our first packaged application, BackWeb Sales
Accelerator.

     Since our inception, revenues have been derived primarily from the
licensing of our products and to a lesser extent from maintenance and support,
consulting and training services. The rate of growth of our service revenues is
not commensurate with the costs of service revenues such as salaries and related
expenses of our customer support and consulting organizations and cost of third
party contractors to provide consulting services. Accordingly, our gross margins
on service revenues are significantly lower than our gross margins on license
revenues. Our products are marketed worldwide through a combination of a direct
salesforce, resellers and system integrators.

     We recognize software license revenue in accordance with Statement of
Position 97-2, or SOP 97-2, "Software Revenue Recognition," as amended by
Statement of Position 98-4, or SOP 98-4. These statements are effective for our
transactions entered into after January 1, 1998. The application of
                                       18
<PAGE>   23

SOP 97-2 has not had a material impact on our results of operations. License
revenues are comprised of perpetual or multi-year license fees that are
primarily derived from contracts with corporate customers and resellers. We
generally recognize license revenues when a license agreement has been executed
or a definitive purchase order has been received and the product has been
delivered to end-user customers, no significant obligations with regard to
implementation remain, the fee is fixed and determinable, and collectibility is
probable. Revenues on contracts with resellers are not recognized until software
is sold through to the end-user.

     Service revenues are primarily comprised of revenues from standard support
and maintenance agreements, consulting and training fees. Customers licensing
our products generally purchase the standard annual maintenance agreement.
Revenues from maintenance agreements are recognized on a straight-line basis
over the life of the agreement. Consulting services are billed at an agreed upon
rate plus out-of-pocket expenses and training services on a per session basis.
We recognize service revenues from consulting and training upon completion of
the work to be performed.

     We have expended significant sums since inception on product development
and enhancement of sales and marketing capabilities, and expect that these
expenditures will continue to increase as we pursue the emerging opportunities
in our markets.

     The functional currency of our operations is the U.S. dollar, which is the
primary currency in the economic environment in which we conduct our business. A
significant portion of our research and development expenses is incurred in NIS.
The results of our operations are subject to fluctuations in the dollar-NIS
exchange rate which is influenced by various global economic factors including
inflation in Israel.

     Because revenues from inception through December 31, 1996 totalled $71,000,
a comparison of our operating results as a percentage of net revenues during
that period or against percentages from later periods is not meaningful.

                               THREE MONTHS ENDED
                            MARCH 31, 1999 AND 1998

     BackWeb incurred a net loss of approximately $3.7 million for the three
months ended March 31, 1999 compared to a net loss of $4.6 million for the three
months ended March 31, 1998.

REVENUES

     Our revenues are derived primarily from licensing of BackWeb Foundation and
BackWeb Sales Accelerator and to a lesser extent from maintenance and support,
consulting and training services. Net revenues increased approximately $2.5
million or 159% from $1.6 million in the three months ended March 31, 1998 to
$4.1 million in the three months ended March 31, 1999. The increase was due to
growth in license revenues. Customers outside of the United States accounted for
18.0% of revenues in the three months ended March 31, 1999 compared to 16.5% of
revenues in the three months ended March 31, 1998.

     License revenues were $3.3 million or 80.7% of revenues in the three months
ended March 31, 1999 compared to $1.4 or 88.3% of revenues in the three months
ended March 31, 1998. The decrease in license revenue as a percentage of total
revenue was primarily due to increased service revenue from support, maintenance
and consulting services. Service revenues were $789,000 or 19.3% of revenues in
the three months ended

                                       20
<PAGE>   25

March 31, 1999 compared to $184,000 or 11.7% of revenues in the three months
ended March 31, 1998. In 1999, we expect our service revenues to increase on an
absolute basis and as a percentage of net revenues.

COST OF REVENUES

     Cost of revenues consists of costs associated with generating license and
service revenues. Cost of revenues was $665,000 or 16.2% of revenues for the
three months ended March 31, 1999 compared to $352,000 or 22.3% of revenues for
the three months ended March 31, 1998. The increase in cost of revenues on an
absolute basis was primarily due to growth of our service organization in 1999.

     Cost of license revenues consists primarily of expenses related to media
duplication, and packaging of our products and amortization of capitalized
developed technology. Cost of license revenues was $73,000 or 1.8% of revenues
for the three months ended March 31, 1999 compared to $55,000 or 3.5% of
revenues for the three months ended March 31, 1998.

     Cost of service revenues consists primarily of expenses related to salaries
and expenses of our customer support and professional service organizations,
including related expenses of our consultants and costs of third party
consultants. Cost of service revenues was $592,000, or 14.4% of revenues, in the
three months ended March 31, 1999 compared to $297,000 or 18.8% of revenues, in
the three months ended March 31, 1998. The increase in cost of service revenues
was due to growth of the service organization during 1998 and 1999.

     We expect cost of service revenues to increase primarily as a result of the
increase in our service revenues in addition to the continued expansion of our
customer support and professional services organizations.

OPERATING EXPENSES

     RESEARCH AND DEVELOPMENT. Research and development expenses consist
primarily of personnel, equipment and supply costs for our development efforts.
These expenses are charged to operations as incurred. We have research and
development offices in Israel and Canada. Research and development expenses were
$997,000 in the three months ended March 31, 1999 compared to $1.3 million in
the three months ended March 31, 1998. The decrease was due to the consolidation
of our research and development facilities in Jerusalem and Ramat Gan.

     We believe significant investment in research and development is essential
to our future success and expect that research and development expenses will
increase on an absolute basis but decrease as a percentage of revenues in future
periods.

     SALES AND MARKETING. Sales and marketing expenses consist of personnel and
related costs for our direct sales force and marketing staff, and marketing
programs, including trade shows, advertising, collateral, sales materials,
seminars and public relations. We have sales personnel in offices located in the
United States, Canada, Europe and Japan. Sales and marketing expenses were $3.8
million in the three months ended March 31, 1999 compared to $3.3 million in the
three months ended March 31, 1998.

     We expect that sales and marketing expenses will increase on an absolute
basis over the next year, as we hire additional sales and marketing personnel,
continue to promote our brand and establish sales offices in additional domestic
and international locations, but are expected to decrease as a percentage of
revenues.

     GENERAL AND ADMINISTRATIVE. General and administrative expenses consist
primarily of personnel and related costs for general corporate functions,
including finance, accounting, general management, human resources, information
services and legal. General and administrative expenses were $931,000 in the
three months ended March 31, 1999 compared to $811,000 in the three months ended
March 31, 1998. We expect general and administrative expenses to increase on an
absolute basis in future periods but continue to decrease as a percentage of
revenues.

     AMORTIZATION OF GOODWILL, OTHER INTANGIBLES AND DEFERRED STOCK
COMPENSATION. Amortization of goodwill, other intangibles and deferred stock
compensation consists of amortization of goodwill and other intangibles
associated with our acquisition of Lanacom in August 1997 and deferred stock
compensation for the three months ended March 31, 1999 and amortization of
goodwill and other intangibles only for the three months ended March 31, 1998.
Deferred stock compensation represents the aggregate differences between the
respective exercise price of options at their dates of grant and the deemed fair
market value or our ordinary shares for accounting purposes. Goodwill and other
intangibles are being amortized on a straight line basis over the estimated
useful life, generally two to two and one-half years. Deferred stock
compensation is presented as a reduction of shareholders' equity and is
amortized over the vesting period of the underlying options based on an
accelerated vesting method. Amortization expense was $1.2 million in the three
months ended March 31, 1999 compared to $401,000 in the three months ended March
31, 1998. The increase in amortization expense was due to deferred stock
compensation expense of $807,000 that was recorded in the three months ended
March 31, 1999.

     We currently expect to record amortization of goodwill, other intangibles
and deferred stock compensation of approximately $4.1 million in 1999, $1.3
million in 2000, $572,000 in 2001 and $235,000 in 2002.

INTEREST INCOME (EXPENSE), NET

     Interest income (expense), net includes interest income earned on our cash
and cash equivalents, offset by interest expense and fair value of warrants
issued in connection with borrowings from financial institutions and also
includes the effects of foreign currency. Net interest expense was $157,000 in
the three months ended March 31, 1999 compared to $18,000 in the three months
ended March 31, 1998. The increase in interest expense was due to interest
payments pursuant to loan agreements.

                                  YEARS ENDED
                        DECEMBER 31, 1998, 1997 AND 1996

REVENUES

     Net revenues were $9.5 million in 1998, $5.6 million in 1997 and $71,000 in
1996. The increase in revenues from 1997 to 1998 was attributable to an increase
in both license revenues and service revenues. The increase in revenues from
1996 to 1997 was due primarily to an increase in license revenues. During 1996,
we had insignificant revenues as we were in the development stage. Revenues from
customers outside of the United States accounted for 20.6% of revenues in 1998
and 11.1% of revenues in 1997. No customer, domestic or international, accounted
for more than 10% of revenues during 1998. However, in 1997, revenues from two
customers represented 19% and 11% of revenues.

     License revenues were $8.0 million, or 83.7% of revenues, in 1998, compared
to $5.3 million, or 94.8% of revenues in 1997. The increase in license revenues
was primarily due to the growth of our customer base, recurring sales to our
installed base and an increase in average transaction size.

     Service revenues were $1.6 million, or 16.3% of revenues, in 1998, compared
to $290,000, or 5.2% of revenues in 1997. The increase in service revenues both
on an absolute basis and as a percentage of revenues was primarily due to
increased revenues from customer maintenance and consulting services as a result
of our efforts to build our customer support and professional services
organizations, a greater number of licenses and the complexity of larger
deployments.

COST OF REVENUES

     Cost of revenues was $1.6 million, or 17.0% of revenues, for 1998 as
compared to $978,000, or 17.5% of revenues, for 1997. The increase in cost of
revenues was due to our increased revenues in 1998. The decrease in cost of
revenues as a percentage of revenues was due to increased utilization of our
customer support and professional services organization in 1998.

     Cost of license revenues was $266,000, or 2.8% of license revenues, in
1998, com-

                                       22
<PAGE>   27

pared to $182,000, or 3.3% of license revenues, in 1997. We expect cost of
license revenues to increase on an absolute basis as a result of increased
license revenues, but remain a small percentage of license revenues.

     Cost of service revenues was $1.4 million in 1998, as compared to $796,000
in 1997. The increase was due primarily to the increased headcount in our
professional services organization and to a lesser extent, our technical support
group. Cost of service revenues in 1997 reflects the establishment of the
service organization infrastructure to support future growth.

OPERATING EXPENSES

     RESEARCH AND DEVELOPMENT. Research and development expenses were $4.6
million in 1998, $4.0 million in 1997 and $1.8 million in 1996. The increases in
research and development expenses were primarily due to the integration of
former Lanacom employees into our research and development organization in
August 1997.

     SALES AND MARKETING. Sales and marketing expenses were $13.2 million in
1998, $12.2 million in 1997 and $4.5 million in 1996. The increases in sales and
marketing expenses were primarily due to our efforts to expand our marketing
programs worldwide, increase brand awareness for our products and adjustments in
our sales force created by our shift from a consumer-oriented to an
enterprise-oriented strategy.

     GENERAL AND ADMINISTRATIVE. General and administrative expenses totaled
$3.2 million in 1998, $3.0 million in 1997, and $1.4 million in 1996. The
increases in general and administrative expenses were due primarily to increased
personnel and related overhead to support our growth.

     AMORTIZATION OF GOODWILL, OTHER INTANGIBLES AND DEFERRED STOCK
COMPENSATION. Amortization of goodwill, other intangibles and deferred stock
compensation expenses totaled $1.8 million in 1998 and $557,000 in 1997.

INTEREST INCOME (EXPENSE), NET

     Net Interest and other income was $218,000 in 1998 and $132,000 in 1997 and
net interest expense was $43,000 in 1996.

INCOME TAXES

     As of December 31, 1998, we had approximately $30.0 million of Israeli net
operating loss carryforwards and $1.0 million of U.S. federal net operating loss
carryforwards and of $4.5 million of other foreign net losses carryforwards for
tax reporting purposes available to offset future taxable income. The U.S. net
operating loss carryforwards expire in various amounts between the years 2011
and 2018. The Israeli net operating loss carryforwards have no expiration date.

     Our quarterly revenues were $1.6 million in the first quarter of 1998 as
compared to $2.5 million in the fourth quarter of 1997, primarily as a result of
our efforts to transition from a consumer-oriented to an enterprise-oriented
strategy. Since the first quarter of 1998 our revenues have grown in each
quarter.

     Our operating results may fluctuate significantly in the future as a result
of a variety of factors, many of which are outside of our control. Additionally,
as a strategic response to a changing competitive environment, we may elect from
time to time to make certain pricing, service, marketing or acquisition
decisions that could have a negative effect on our quarterly financial
performance. Our past has shown that a significant percentage of our quarterly
revenues come from orders placed by a small number of customers and are realized
toward the end of a quarter. A delay in the execution of a sale past the end of
a particular quarter could negatively impact results for that particular
quarter. In addition, we expect that revenues in the first quarter of each year
will be lower than the last quarter of the previous year primarily due to the
annual nature of budgetary, procurement and sales cycles.

                        LIQUIDITY AND CAPITAL RESOURCES

     Since our inception, we have funded operations primarily through the
private placement of our equity securities, equipment lease financings and
borrowings. As of March 31, 1999, we had cash and cash equivalents of $11.1
million. Cash used by operations include expenditures associated with
development activities and marketing efforts related to commercialization of our
products. In the three months ended March 31, 1999, cash used in operations was
$5.0 million. In 1998, cash used in operations was $11.9 million, comprised of
the net loss of $14.6 million and partially offset by noncash charges of $2.5
million. In 1997, cash used in operations was $15.5 million comprised of the net
loss of $15.0 million, an increase in accounts receivable of $3.3 million,
partially offset by noncash charges of $917,000 and an increase in deferred
revenues of $1.0 million.

     We have made investments in hardware, software, and furniture and fixtures.
Expenditures on property and equipment were approximately $134,000 in the three
months ended March 31, 1999, $390,000 in 1998, $860,000 in 1997 and $498,000 in
1996.

     We have raised approximately $48.0 million, net of issuance costs, from
equity sales since our inception through March 31, 1999. In the three months
ended March 31, 1999, we raised $9.9 million through the sale of preferred
shares. In 1998, we raised $11.8 million through the sales of preferred shares.
In 1997, we raised $9.2 million through the sales of preferred shares. In 1996,
we raised $16.8 million through sales of preferred shares. From inception
through March 31, 1999, we raised $309,000 through the issuance of our ordinary
shares pursuant to the exercise of stock options.

     Additionally, we have used debt to partially finance our operations and
capital purchases. In December 1998, we entered into a $6.5 million secured
credit facility which is secured by substantially all of our assets. This
facility includes a $1.5 million equipment line, a $3.0 million receivable line
and a $2.0 million non-formula facility. At March 31, 1999, we had borrowed $2.0
million under the non-formula facility which bears interest at the rate of prime
plus 4% per annum. In 1995 and 1996 we obtained loans from some of our
shareholders in the aggregate amount of $1.2 million of which $927,000 remained
outstanding as of March 31, 1999. The loans are linked to the Israeli consumer
price index. The loans do not bear interest and are payable at a rate of 2.5% of
cumulative consolidated revenues in excess of $5.0 million. We intend to repay
these loans with the proceeds from this offering.

     Our capital requirements depend on numerous factors, including market
acceptance of our products, the resources we devote to developing, marketing,
selling and supporting our products, the timing and extent of establishing
additional international operations and other factors. We expect to devote
substantial capital resources to hire and expand our sales, support, marketing
and product development organizations, to expand marketing programs, to
establish additional facilities

                                       25
<PAGE>   30

worldwide and for other general corporate activities. We believe that our
current cash balances along with the proceeds raised from this offering will be
sufficient to fund our operations for at least the next 18 months.

                         EFFECTIVE CORPORATE TAX RATES

     Our tax rate will reflect a mix of the U.S. statutory tax rate on our U.S.
income and the Israeli tax rate discussed below. We expect that most of our
taxable income will be generated in Israel. Israeli companies are generally
subject to income tax at the rate of 36% of taxable income. The majority of our
income, however, is derived from our company's capital investment program with
"Approved Enterprise" status under the Law for the Encouragement of Capital
Investments, and is eligible therefore for tax benefits. Pursuant to these
benefits, we will enjoy a tax exemption on income derived during the first two
years in which this investment program produces taxable income, provided that we
do not distribute such income as a dividend, and a reduced tax rate of 15-25%
for the next 5 to 8 years. All of these tax benefits are subject to various
conditions and restrictions. See "Israeli Taxation and Investment Programs-Law
for the Encouragement of Capital Investments, 1959." There can be no assurance
that we will obtain approval for additional Approved Enterprises Programs, or
that the provisions of the law will not change.

     Since we have incurred tax losses through December 31, 1998, we have not
yet used the tax benefits for which we are eligible. See "Risk Factors" and Note
9 to the Consolidated Financial Statements.

                 IMPACT OF INFLATION AND CURRENCY FLUCTUATIONS

     Most of our sales are in U.S. dollars. However, a large portion of our
costs relate to our operations in Israel. A substantial portion of our operating
expenses, primarily our research and development expenses, is denominated in
NIS. Costs not effectively denominated in U.S. dollars are translated to U.S.
dollars, when recorded, at prevailing exchange rates for the purposes of our
financial statements, and will increase if the rate of inflation in Israel
exceeds the devaluation of the Israeli currency as compared to the U.S. dollar
or if the timing of such devaluations were to lag considerably behind inflation.
Consequently, we are and will be affected by changes in the prevailing NIS/ U.S.
dollar exchange rate. We might also be affected by the U.S. dollar exchange rate
to the major European and Asian currencies due to the fact that we operate
offices throughout Europe and Asia.

     The annual rate of inflation in Israel was 8.6% in 1998, 7.0% in 1997 and
10.6% in 1996. The NIS was devalued against the U.S. dollar by approximately
17.6% in 1998, 8.8% in 1997 and 3.8% in 1996.

     The representative dollar exchange rate for converting the NIS to dollars,
as reported by the Bank of Israel, was NIS 4.04 for one U.S. dollar on March 31,
1999.

                                   YEAR 2000

RISKS POSED BY YEAR 2000

     We recognize that we must ensure that our products and services will not be
adversely affected by Year 2000 software failures. Although we have taken
actions and created procedures to ensure our own products and services will
properly handle the Year 2000 date change. We have tested all current products
for Year 2000 compliance. We used industry standard testing methods for Year
2000 compliance to ensure our products were compliant. These tests and methods
were run on all current and many previous versions of our products on all
current platforms. Based on results of these tests and methods, we believe our
current products are Year 2000 compliant with respect to date calculations and
internal storage of date information. However, previous versions of our products
may not be Year 2000 compliant. To the extent these products are still being
used by our customers, we are subject to the risk that these products will not
function properly with respect to the Year 2000.

     Although we do not have a formal contingency plan to address Year 2000
issues, we are in the preliminary stages of assessing our internal risks
associated with the Year 2000 issue. We are working internally and with
third-party vendors to assure that we are prepared for the Year 2000. We have
invento-

                                       26
<PAGE>   31

ried our internal software and hardware systems, as well as products and
services provided by third-party vendors. These systems include those related to
product delivery, customer service, internal and external communications,
accounting and payroll, which we consider critical areas of our business. We
presently will be seeking vendor certification for all third-party systems and
plan to develop a detailed risk assessment and action plan that will include
testing of both critical systems and systems for which no certification has been
obtained. The identification, certification and risk assessment phases of our
Year 2000 project are expected to be completed by the end of July 1999.
Subsequent phases will include our own tests and the development of contingency
plans and/or corrective solutions for systems which have been identified to be
noncompliant. We expect these phases will continue through the first three
quarters of 1999.

     We believe that our most reasonably likely worst-case scenarios related to
the year 2000 problem are:

     - a significant year 2000 problem encountered by us could result in
       disruption of our communication links between our development staff in
       Israel and Toronto, our staff in San Jose, California and our other
       domestic and international locations;

     - a significant year 2000 problem encountered by us could result in
       disruption of our ability to communicate and receive orders from our
       customers and to provide support and consulting services; or

     - a failure of or degradation in performance due to year 2000 issues
       encountered by a substantial proportion of the systems that carry
       Internet traffic, which could negatively affect the performance of our
       products and the demand for our products.

COSTS POSED BY YEAR 2000 COMPLIANCE

     To date, our costs to address Year 2000 compliance have not been
significant. Based on our preliminary evaluations, we do not believe we will
incur significant operating expenses or be required to invest heavily in
computer system improvements to be Year 2000 compliant. Although we have not yet
developed an exact estimate of these costs, we expect the total costs to be less
than $100,000. However, significant uncertainty exists concerning the potential
costs and effects associated with Year 2000 compliance.

           QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK

     We develop products in Israel and sell them in North America, Asia and
Europe. As a result, our financial results could be affected by factors such as
changes in foreign currency exchange rates or weak economic conditions in
foreign markets. As most of our sales are currently made in U.S. dollars, a
strengthening of the dollar could make our products less competitive in foreign
markets. Our interest income is sensitive to changes in the general level of
U.S. interest rates, particularly since the majority of our investments are in
short-term instruments. Backweb regularly assesses these risks and has
established policies and business practices to protect against the adverse
effects of these and other potential exposures. As a result, the Company does
not anticipate material losses in these areas. Due to the nature of our
short-term investments, we have concluded that there is no material market risk
exposure. Therefore, no quantitative tabular disclosures are required.

                        RECENT ACCOUNTING PRONOUNCEMENTS

     In March 1998, the American Institute of Certified Public Accountants
issued SOP 98-1, "Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use" ("SOP 98-1"). SOP 98-1 requires that entities
capitalize certain costs related to internal use software once certain criteria
have been met. We are required to implement SOP 98-1 for the year ending
December 31, 1999. The adoption of SOP 98-1 is expected to have no material
impact on our financial condition and results of operations.

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS 133"). We are required to adopt SFAS
133 for the year ending December 31, 2000. SFAS 133

                                       27
<PAGE>   32

establishes methods of accounting for derivative financial instruments and
hedging activities. Since we currently hold no derivative financial instruments
as defined by SFAS 133 and do not currently engage in hedging activities,
adoption of SFAS 133 is expected to have no material effect on our financial
condition or results of operations.

     In December 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-9, "Modification of SOP 97-2, Software Revenue
Recognition, With Respect to Certain Transactions" ("SOP 98-9"). SOP 98-9 amends
SOP 98-4 to extend the deferral of the application of certain passages of SOP
97-2 provided by SOP 98-4 through fiscal years beginning on or before March 15,
1999. All other provisions of SOP 98-9 are effective for transactions entered
into in fiscal years beginning after March 15, 1999. We have not yet determined
the effect of the final adoption of SOP 98-9 on our financial condition or
results of operations.

                           BACKWEB TECHNOLOGIES, LTD.

     BackWeb is a leading provider of Internet communication infrastructure
software and application-specific software that enables companies to communicate
business-critical, time-sensitive information throughout their extended
enterprise of customers, partners and employees. Our products provide a reliable
solution for communicating large amounts of data in any digital format by
enabling our customers to automatically gather and disseminate information. Our
products efficiently disseminate this information across a network of any speed
by automatically adapting the rate of transmission to match available bandwidth.

     Our infrastructure software, BackWeb Foundation, is a platform that allows
organizations to efficiently gather, target and deliver sizeable digital data of
any format to users' desktops throughout the extended enterprise. We work with
our customers, partners and third-party software vendors to develop applications
built on top of BackWeb Foundation. We have also developed our own application,
BackWeb Sales Accelerator. BackWeb Sales Accelerator enables a geographically
dispersed sales organization to stay instantly updated about competitive and
customer information from external sources, internal sales and marketing
materials, product pricing information, business applications and critical
management announcements.

                              INDUSTRY BACKGROUND

     The Internet has changed the nature of business operations and competition.
Companies, their suppliers, customers and employees now have the means to
conduct business electronically, commonly referred to as e-business. As a
result, it is now possible for new competitors to enter and disrupt established
markets virtually overnight. The spread of electronic commerce has endowed
business customers and consumers with the ability to change vendors at the click
of a button. To compete effectively, companies need to react quickly to changing
market conditions, accelerate critical business processes and stay in closer
contact with sales people, partners and customers. To address these challenges,
companies must be able to effectively communicate the right information to the
right people at the right time. Existing Internet communication methods fall
short of the requirements of this new business environment, as these methods do
not overcome the network congestion, information overload and lack of
reliability characteristic of today's networks.

     Companies face the complex challenge of reacting quickly to changes in the
competitive landscape and reliably communicating and tracking time-sensitive,
business-critical information throughout their extended enterprise. The
ineffectiveness of overloaded e-mail systems, passive websites and other
existing means of communication has impeded communication of information between
organizations and their customers, partners and employees. Companies using
existing means of communication are often unable to prioritize and personalize a
communication so that it receives the appropriate level of attention. Once a
communication is sent, companies cannot easily track the communication to ensure
it was received and interacted with, and further, are unable to elicit feedback.
In addition, recipients are inundated with information and lack an effective
means of immediately determining the importance and relevance of information
received, assigning priorities to that information and communicating their
responses. Consequently, recipients often react to this flood of information by
ignoring it or failing to respond in a timely manner. This often results in lost
business opportunities and foregone revenues.

     Companies that need to communicate large amounts of digital data are often
limited by the capacity of their network connections and resources.
Bandwidth-intensive data, such as audio, video and multimedia presentations,
software applications and updates, overloads the constrained network resources
of the extended enterprise. Meanwhile, the recipients of large data files are
forced to either disrupt their work in progress or to postpone the download of
the

                                       29
<PAGE>   34

file, which may be extremely time-sensitive. These problems are compounded when
users are remote or mobile and become even more complicated when multiple
networks interact.

     We believe that in order for the Internet to be used efficiently as an
effective communication medium across the extended enterprise, a complementary,
more sophisticated infrastructure must be introduced. This new communication
infrastructure must:

     - permit the prioritization of communications to ensure that users are
       presented with relevant information in a manner designed to ensure that
       these communications receive the appropriate level of attention;

     - communicate large amounts of digital data in any format quickly and
       efficiently with a minimal impact on the network of a company and its
       extended enterprise;

     - permit tracking of the communication by management and the interaction
       between management and the user; and

     - be an open platform that facilitates the development of applications that
       are scalable and easy to deploy.

                              THE BACKWEB SOLUTION

     We develop, market and support Internet communication infrastructure and
applications software that enables companies to communicate business-critical
information to their customers, partners and employees. Our software enables
companies to efficiently target, deliver and track the use of sizeable digital
data in any format throughout their extended enterprise. Using our products and
technology, companies can ensure that the right information reaches the right
people at the right time.

     Our products and technology provide the following benefits:

IMPROVE NETWORK EFFICIENCY AND BANDWIDTH UTILIZATION

     Our unique technology significantly increases the efficiency and
reliability of communications over the Internet. Our Polite Agent technology
adapts the rate of transmission to match the bandwidth that is available to
ensure that BackWeb-generated traffic does not interfere with other network
traffic on the desktop connection. Our Polite Proxy server technology adapts
BackWeb traffic to utilize available bandwidth on the wide area network, or WAN,
connection. Our Polite Neighborcast technology enables each BackWeb client to
serve as an intelligent cache for other BackWeb clients. As a result, data is
delivered only once to a local area network, or LAN, after which it is
intelligently distributed to neighboring clients, thereby resulting in a fast
and efficient distribution of data. Our network efficiency is further enhanced
by our ability to reduce redundant network traffic by automatically transmitting
only the information that has changed since the user's previous download. In
addition, if a transmission is interrupted, it resumes at the point where it was
cut off, thereby eliminating the need to re-send the entire transmission. As a
result of these capabilities, data transmission across the extended enterprise
is scalable, transparent and efficient.

PRIORITIZE AND CONTROL THE COMMUNICATIONS FLOW

     Our software enhances the management of critical information throughout the
extended enterprise. Companies can readily control the destination, access
rights and priority of information being communicated. Business managers can use
our software to determine the effectiveness of their communications through
reports on delivery, usage and interactions. In addition, our products can close
the communication loop by allowing managers to collect feedback from users and
process, review and communicate this feedback throughout the extended
enterprise. Further, business managers can use our tools to automate the
collection and dissemination of information from digital sources such as news
feeds, databases, legacy systems and competitors' websites, resulting in reduced
management time and resources dedicated to data acquisition.
                                       30
<PAGE>   35

CAPTURE IMMEDIATE ATTENTION TO CRITICAL INFORMATION

     Our unique attention management technology incorporates intelligent
notification techniques to address the challenge of capturing attention in a
world of growing information overload. Our software increases the effectiveness
of communications throughout the extended enterprise by personalizing the
distribution of information. For example, the communication can be customized to
require the user to acknowledge receipt of the information or to automatically
launch a designated application. In addition, not only can business managers
determine the recipients of particular information, but recipients can also
subscribe to various information sources. These capabilities ensure recipients
that the information being received is important to them, and, as a result,
significantly increases the likelihood that it will be reviewed and acted upon.
In addition, the ability to elicit return responses results in greater
effectiveness of the overall communication.

                                    STRATEGY

     Our objective is to establish ourselves as the leading provider of Internet
communication infrastructure and applications software. The key elements of this
strategy include:

BECOME THE DE FACTO STANDARD FOR INTERNET COMMUNICATION INFRASTRUCTURE

     We intend to establish BackWeb Foundation as the leading infrastructure
software platform for Internet communication. We believe that the recent
adoption of BackWeb Foundation by leading companies across various industries
validate our technology and should facilitate its broad market acceptance. In
addition, we believe that the selection of our products by industry leaders
should promote the adoption of our Internet communication solution by these
companies' partners, suppliers and distributors. We also believe that this
adoption, along with the competitive advantages achieved with our products, will
drive other industry participants to adopt our products as their preferred
solution. We intend to continue to focus our development efforts on increasing
the functionality and flexibility of BackWeb Foundation to facilitate its
continued adoption and to increase the technological barriers to entry.

LEVERAGE INFRASTRUCTURE PLATFORM TO INTRODUCE MULTIPLE INTERNET COMMUNICATION
APPLICATIONS

     Our core technology has been designed as an open platform upon which
BackWeb, our customers, our partners and third-party vendors can develop
Internet communication applications that are easy to deploy and to which
additional capabilities can easily be added. We actively market and support our
first application built on top of our infrastructure software, BackWeb Sales
Accelerator, which enables companies to focus the attention of their sales
forces, partners and customers on timely, business-critical information. We
intend to increase our product offerings by introducing new applications,
developed both internally and through third-parties, targeted at various
business functions throughout the extended enterprise.

FOCUS ON SELECTED VERTICAL MARKETS

     We target selected vertical markets where we believe our solutions offer
significant value. To date, these markets have included telecommunications, high
technology, financial services, retail and travel services. Within each
industry, we typically target the leader and then leverage our success to
generate additional sales to other companies in that market. We also partner
with large applications vendors and systems integrators that serve these
vertical markets. Through these strategic partnerships, we are able to
significantly expand our installed base as our products are incorporated into
the vendor's products and systems integrator's custom-developed applications. We
and our partners can, in turn, use this installed base to develop and market
BackWeb Foundation and additional BackWeb Foundation-based applications.

EXTEND TECHNOLOGICAL LEADERSHIP POSITION

     We intend to continue to devote substantial resources to the development of
new and innovative software products and technologies. We believe that our early
understanding

                                       31
<PAGE>   36

and penetration of the market for Internet communication infrastructure software
has allowed us to establish technological leadership and a time-to-market
advantage. We intend to extend our leadership position and build further
technological barriers to entry by enhancing the functionality of our current
BackWeb Foundation infrastructure software platform and developing innovative
applications on top of it.

EXPAND DIRECT AND INDIRECT DISTRIBUTION CHANNELS

     We have established a direct sales force in the United States and Canada
and use a combination of direct and indirect channels in Europe and Japan. We
intend to increase the size of our direct sales force and to establish
additional sales offices both domestically and internationally. We intend to
continue to complement our direct sales force by establishing multiple
additional indirect distribution channels worldwide through original equipment
manufacturers, large applications vendors and systems integrators. These
indirect channels are intended to increase geographic sales coverage and address
potential customers that would otherwise be beyond the reach of our direct sales
organization.

                            TECHNOLOGY AND PRODUCTS

     We currently sell BackWeb Foundation and BackWeb Sales Accelerator. We
license BackWeb Foundation to customers, developers and independent software
vendors, thereby enabling them to integrate their own applications or
third-party applications with our infrastructure software platform. BackWeb
Sales Accelerator provides our customers with a packaged application that
incorporates BackWeb Foundation.

TECHNOLOGY

     Our infrastructure software platform is powered by three core technologies
that we have developed: Polite Communications, Attention Management and Closed
Loop Delivery.

     POLITE COMMUNICATIONS. Polite Communications enables the transmission of
significant volumes of digital data through existing networks without
interfering with normal network applications and traffic. Polite Communications
enables companies to provide any user with rapid communication of
bandwidth-intensive data, regardless of whether they utilize high-speed data
access services. This bandwidth-sensitive delivery is accomplished through the
use of various components including the following:

     - POLITE AGENT monitors the network activity of the client workstation and
       communicates with BackWeb servers only when the connection is idle.

     - POLITE PROXY monitors wide area network, or WAN, connections in the same
       manner, using available bandwidth.

     - POLITE NEIGHBORCAST enables the automatic transmission of digital data
       from one BackWeb Client to others on the same local area network, or LAN,
       obviating the need for transmission of the data from the server to each
       BackWeb Client. The transmission from BackWeb Client to BackWeb Client on
       the same LAN is a fast, efficient and cost-effective means of
       disseminating the data.

     - POLITE UPSTREAM enables the automatic transmission of digital data from
       BackWeb Clients to the BackWeb Server when the network connection is
       idle.

     Polite Communications further improves the efficiency of transmission by
reducing the amount of data to be transmitted through various techniques,
including:

     - compression of data;

     - updating only the information which has changed since the user's previous
       download; and

     - eliminating the need to re-send an interrupted transmission by
       progressively resuming the transmission at the point where it was
       interrupted.

     ATTENTION MANAGEMENT AND FLASH NOTIFICATIONS. Attention Management is an
automatic notification system that alerts users to the delivery of
business-critical information through a variety of display techniques including
tickers and Flash notifications. These
                                       32
<PAGE>   37

techniques enable companies to attract immediate attention to time-sensitive
information. Flashes are a particular display technique that can be customized
to notify users and, if desired, can allow management to track the usage of the
information. For example, the recipient can be required to acknowledge their
receipt of the information, or to immediately launch and interact with a
designated application. In addition, Attention Management displays can be
programmed to play automatically according to specific scheduling and expiration
parameters, after which the information and associated data can be automatically
purged.

     CLOSED LOOP DELIVERY. Our Closed Loop Delivery capabilities allow companies
to track, manage and survey the effectiveness of communications throughout their
extended enterprise. Companies can track the status and use of any digital data
delivered via BackWeb or generate reports on the overall usage of the system on
a per-user or per-content basis. Using these reports, companies can determine
what types of communication are most effective or most popular and adapt their
communication strategy appropriately.

PRODUCTS

     BACKWEB FOUNDATION. Our infrastructure software platform, BackWeb
Foundation, is based on a set of flexible components including BackWeb Server,
BackWeb Client and BackWeb Add-On Components. These components enable an
organization to capture information from virtually any data source, including
websites, file servers, databases, applications and legacy systems, and
efficiently and reliably deliver it throughout its extended enterprise. BackWeb
Server is a software server which runs on standard hardware servers, and
communicates with BackWeb Client, our software program operating on personal
computers or workstations.

     BackWeb Server. BackWeb Server communicates with BackWeb Clients and is
capable of receiving digital data from various sources, such as the Internet,
intranet sites, databases, applications and legacy systems and automatically
distributes that data to BackWeb Clients. The BackWeb Server is highly scalable
and optimized to support a large number of clients concurrently. Components of
BackWeb Server include:

     - BackWeb Server Console. A console that allows a system administrator to
       manage BackWeb Server and control the information flow across the
       enterprise through a point-and-click graphical user interface.

     - BackWeb Server Extension API. An application programming interface that
       allows companies to integrate the BackWeb Server with any digital data
       source, enabling automated publishing of content or files from any source
       to the BackWeb Server.

     - BackWeb Automation SDK and Automation Editor. Includes application
       programming interfaces and a library of BackWeb-supplied programs which
       perform tasks between the BackWeb Server and external data sources.

     - BackWeb BALI Editor. Our BackWeb Authoring Language Interface Editor is
       used by companies to create and modify Flashes.

     BackWeb Client. BackWeb Client, our software program operating on personal
computer or workstations, operates in the background and communicates with
designated BackWeb Servers during the idle time of a user's network connection,
thereby allowing the user to receive data transparently while using other
applications without disruption. BackWeb Client:

     - displays information through Flashes and other displays and user
       interfaces, which may be customized;

     - provides an application programming interface to enable customer and
       third-party applications to integrate with BackWeb Client; and

     - can be deployed by a single automatic installation file of less than 100k
       in size that can be sent to the user via the Internet, e-mail or floppy
       disk.

     BackWeb Add-On Components. BackWeb Foundation, our infrastructure software
plat-

                                       33
<PAGE>   38

form, also includes the following add-on components:

     - BackWeb Enhanced Security Module. Provides encrypted communications
       between BackWeb Server and BackWeb Clients and certificate authentication
       of data packages. This module incorporates industry standard technologies
       from RSA Data Security and Verisign.

     - BackWeb AutoFile Update Manager. Enables the automatic replication of
       files or file directories from any directory accessible to the BackWeb
       Server. Allows the placement of the replicated files in any location on
       the user's system. Allows management to have complete flexibility over
       the organization of information on the user's desktop.

     - StarBurst Connector. In cooperation with StarBurst, we created optional
       add-ons to the BackWeb Server and BackWeb Client that allow them to
       communicate via StarBurst's multicasting Internet protocol. These add-ons
       work in concert with our protocols to provide a deeply integrated
       communications solution for customers with multicast Internet protocol
       environments.

     - NewsEdge and Reuters BackWeb Connectors. In cooperation with the NewsEdge
       and Reuters corporations, we created a pre-packaged set of connectors to
       their content for the automatic feed of information channels from
       NewsEdge and Reuters, respectively, to a customer's BackWeb Server.

     - BackWeb Polite Proxy Server. A software server that:

     -- caches frequently accessed material for a group of BackWeb clients,
        eliminating the need for redundant data transfers from a company's
        server;

     -- monitors the WAN connection and communicates only when the network
        connection is below a certain threshold; and

     -- enables a system administrator to manage the BackWeb Proxy Server
        Console.

     BACKWEB SALES ACCELERATOR. In December 1998, we introduced BackWeb Sales
Accelerator, our first packaged application built on BackWeb Foundation. BackWeb
Sales Accelerator allows companies to keep their extended enterprise equipped
with the most up-to-date documents, market information and management
announcements by automating the collection and dissemination of business
critical information. This application is targeted at companies that need to
communicate to geographically dispersed sales forces and indirect sales channels
to accelerate their business execution and response time to critical changes
affecting their business. Examples of information typically communicated by
BackWeb Sales Accelerator include:

     - competitive and industry news and announcements;

     - new pricing policies and updated price lists;

     - product release announcements and associated fact sheets, white papers,
       and training materials;

     - new or updated software tools;

     - critical executive announcements, in video or other formats, regarding
       company acquisitions or strategic priorities; and

     - new or modified sales presentations and demonstrations.

     BackWeb Sales Accelerator consists of the Market Intelligence Manager,
Strategic Publishing Manager and Automated Marketing Encyclopedia modules:

     - Market Intelligence Manager automatically monitors, collects and
       organizes information from Internet or intranet sites to keep an
       organization's sales force abreast of the latest industry news,
       competitive announcements and customer information.

     - Strategic Publishing Manager enables managers to publish and direct the

                                       34
<PAGE>   39

       immediate attention of their constituents to time-sensitive and business
       critical information. Editorial, publishing and access rights are
       centrally controlled. The published information can be disseminated to
       users' desktops using our Flash technology.

     - Automated Marketing Encyclopedia enables a company to create a library of
       sales information and productivity software to which extended enterprise
       users can subscribe. Once subscribed, users automatically receive this
       information, software and any subsequent updates.

                                   CUSTOMERS

     We sell our products to a broad base of customers from a variety of
industries, including telecommunications, high technology, financial services,
retail and travel services. Our customers include industry leaders such as:
AT&T, barnesandnoble.com, British Telecom, Carlson Travel, Cisco Systems,
Compaq, Computer Associates, Delta Airlines, Electronic Data Systems, Fidelity
Investments, Galileo, Gateway, Goldman Sachs, Hewlett-Packard, AC Nielsen,
Network Associates, o.tel., Pacific Bell, RiteAid, Schlumberger and Siemens.

     In 1997, revenues from Computer Associates and CompuServe represented 19%
and 11%, respectively, of our revenues. In 1998, no customer accounted for more
than 10% of our revenues.

                              SALES AND MARKETING

     Our sales strategy is to pursue opportunities with large accounts and
industry leaders through our direct sales force, and to penetrate various
targeted market segments through multiple indirect distribution channels and
strategic partnerships.

     We maintain direct sales personnel in the United States, Canada, Japan and
Europe. The direct sales force consists of sales representatives, systems
engineers and telemarketing representatives.

     We intend to increase the size of our direct sales force and to establish
additional sales offices domestically and internationally. Competition for sales
personnel is intense, and we may not be able to attract, assimilate or retain
additional qualified personnel in the future.

     We also partner with large applications vendors and systems integrators
that serve our target markets. Through these strategic partnerships, we are able
to significantly expand our installed base as our products are incorporated into
the vendor's products and systems integrator's custom-developed applications.
This installed base can, in turn, be leveraged by us and our partners to develop
and market BackWeb Foundation and additional BackWeb Foundation-based
applications. We are in the early stages of building these channels and
currently have entered into written agreements with a limited number of
companies. We may not be able to enter into agreements or establish
relationships with desired distribution partners on a timely basis or ensure
that such distribution partners will devote adequate resources to selling our
products.

     We believe it is important to have a strong international presence. We have
established sales offices in the United States, Canada, Japan and a number of
countries in Europe. We intend to hire additional sales and marketing personnel
in these offices and to establish additional offices to support our
international operations.

     We market our products using public relations activities, partners
marketing, advertising, trade shows and marketing and sales materials.

                          CUSTOMER SERVICE AND SUPPORT

     We are in the process of developing a comprehensive service and support
organization. Our services are primarily comprised of technical support,
consulting and training.

     Our technical support is provided to our customers on an annual basis for
an additional fee. This support includes remote assistance with installation,
configuration and initial set-up of the application, run-time support and
software maintenance releases.
                                       35
<PAGE>   40

     We also provide consulting, training and on-site installation services. We
expect to expand our variety of services both directly and through third-party
relationships in order to meet the growing needs of our customers.

                            RESEARCH AND DEVELOPMENT

     We believe that strong product development capabilities are essential to
our strategy of enhancing our core technology, developing additional
applications, incorporating that technology and maintaining the competitiveness
of our product and service offerings. We have invested significant time and
resources in creating a structured process for undertaking all product
development projects.

     In addition, we have actively recruited key computer scientists, engineers
and software developers and have complemented these individuals by hiring senior
management with backgrounds in the commercial software development industries.
Through our acquisition of Lanacom, we enhanced our research and development
capabilities, particularly with respect to the development of software
applications.

     Since our inception, we have focused our research and development efforts
on developing and enhancing BackWeb Foundation and BackWeb Sales Accelerator.
BackWeb is currently working on new applications and adding features and new
functionality to our products. Our research and development expenses totaled
$997,000 for the three months ended March 31, 1999, $4.6 million for the year
ended December 31, 1998, $4.0 million for the year ended December 31, 1997, and
$1.8 million for the year ended December 31, 1996.

                                  COMPETITION

     We compete in markets that are new, intensely competitive, highly
fragmented and rapidly changing. We have experienced and expect to continue to
experience increased competition from current and potential competitors. Many of
these companies have greater name recognition, longer operating histories,
larger customer bases and significantly greater financial, technical, marketing,
public relations, sales, distribution and other resources. In addition, some of
our potential competitors are among the largest and most well-capitalized
software companies in the world. We expect to face competition from these and
other competitors, including:

     - companies addressing certain segments of our market such as Marimba and
       Tibco;

     - sales force automation and enterprise resource planning, or ERP, vendors
       that may introduce products competitive to BackWeb Sales Accelerator; and

     - communications and information management platform companies such as IBM
       and its subsidiary Lotus Development Corporation, Microsoft and Sun
       Microsystems.

     Additional competition could come from operating system vendors, online
service providers, client/server applications and tools vendors, multimedia
companies, document management companies and network management vendors. If any
of our competitors were to become the industry standard or were to enter into or
expand relationships with significantly larger companies through mergers,
acquisitions or otherwise, our business and operating results could be seriously
harmed. In addition, potential competitors may bundle their products or
incorporate functionality into existing products in a manner that discourages
users from purchasing our products.

     We expect that competition will increase in the near term and that our
primary long-term competitors may not have entered the market yet. Increased
competition could result in price reductions, fewer customer orders, reduced
gross margin and loss of market share, any of which could cause our business to
suffer.

                  INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

     Our products and services operate in part by making copies of material
available on the Internet and other networks and making this material available
to end-users from a central location. This creates the potential for claims to
be made against us, either directly or through contractual indemnification
provisions
                                       36
<PAGE>   41

with customers, including defamation, negligence, copyright or trademark
infringement, personal injury, invasion of privacy or other legal theories based
on the nature, content or copying of such materials. These claims have been
brought and sometimes successfully pressed against online service providers in
the past. It is also possible that if any such information, or information that
is copied and stored by customers that have deployed our products, contains
errors, third parties could make claims against us for losses incurred in
reliance on such information. Although we carry general liability insurance, our
insurance may not cover potential claims of this type or may not be adequate to
indemnify us for all liability that may be imposed.

     Our success and ability to compete are substantially dependent upon our
internally developed technology. While we rely on patent, copyright, trade
secret and trademark law to protect our technology, we believe that factors such
as the technological and creative skills of our personnel, new product
developments, frequent product enhancements and reliable product maintenance are
more essential to establishing and maintaining a technology leadership position.
Others may develop technologies that are similar or superior to our technology.

     We generally enter into confidentiality or license agreements with our
employees, consultants and corporate partners, and generally control access to
and distribution of our software, documentation and other proprietary
information. Despite our efforts to protect our proprietary rights, unauthorized
parties may attempt to copy or otherwise obtain and use our products or
technology. Policing unauthorized use of our products is difficult, and the
steps we have taken might not prevent misappropriation of our technology,
particularly in foreign countries where the laws may not protect our proprietary
rights as fully as do the laws of the United States.

     Substantial litigation regarding intellectual property rights exists in the
software industry. We expect that software products may be increasingly subject
to third-party infringement claims as the number of competitors in our industry
segments grows and the functionality of products in different industry segments
overlaps. We believe that many of our competitors have filed or intend to file
patent applications covering aspects of their technology that they may claim our
technology infringes. Third parties may claim infringement by us with respect to
our products and technology. Any such claims, with or without merit, could:

     - be time-consuming to defend;

     - result in costly litigation;

     - divert management's attention and resources;

     - cause product shipment delays; or

     - require us to enter into royalty or licensing agreements.

     Royalty or licensing agreements, if required, may not be available on
acceptable terms, if at all. A successful claim of product infringement against
us and our failure or inability to license the infringed or similar technology
could harm our business.

                                   EMPLOYEES

     As of March 31, 1999, we had a total of 158 employees, 151 of whom were
full-time employees. Of the total number of employees 56 were engaged in
research and development including 7 part-time employees, 64 in sales, marketing
and business development, 16 in professional services and technical support and
22 in finance, administration and operations. Our future performance depends in
significant part upon the continued service of our key technical, sales and
senior management personnel, none of whom is bound by an employment agreement
requiring service for any defined period of time. The loss of the services of
one or more of our key employees could have a material adverse effect on our
business, financial condition and results of operations. Our future success also
depends on our continuing ability to attract, train and retain highly qualified
technical, sales and managerial personnel. Competition for such personnel is
intense, and we may not be able to retain our key personnel in the future. None
of our employees is represented by a labor union. We have not experienced

                                       37
<PAGE>   42

any work stoppages and considers our relations with our employees to be good.

     In addition, 45 of our employees are located in Israel. Israeli law and
certain provisions of the nationwide collective bargaining agreements between
the Histadrut, which is the General Federation of Labor in Israel, and the
Coordinating Bureau of Economic Organizations which is the Israeli federation of
employers' organizations, apply to our Israeli employees. These provisions
principally concern the maximum length of the work day and the work week,
minimum wages, contributions to a pension fund, insurance for work-related
accidents, procedures for dismissing employees, determination of severance pay
and other conditions of employment. Furthermore, pursuant to such provisions,
the wages of most of our employees are subject to cost of living adjustments,
based on changes in the Israeli Consumer Price Index. The amounts and frequency
of such adjustments are modified from time to time. Israeli law generally
requires the payment of severance pay upon the retirement or death of an
employee or upon termination of employment by the employer or, in certain
circumstances, by the employee. We currently fund our ongoing severance
obligations for our Israeli employees by making monthly payments for insurance
policies to cover these obligations.

                                   FACILITIES

     BackWeb leases approximately 5,400 square feet in a single office building
located in Ramat Gan, Israel and approximately 14,365 square feet in a single

                             ELECTION OF DIRECTORS

     Our Articles of Association provide for a board of directors of not less
than four members nor more than seven. There are currently five directors on our
Board. We currently have a classified Board of Directors consisting of one Class
I director, Joseph Gleberman, two Class II directors, William Larson and Charles
Federman and two Class III directors, Eli Barkat and Gil Schwed. These directors
have been elected to serve until the annual meetings of shareholders to be held
in 2000 for the Class I director, 2001 for the Class II directors and 2002 for
the Class III directors. These provisions, when coupled with the provision of
our Articles of Association authorizing our Board to fill vacant directorships
or increase the size of the Board, may deter a shareholder from removing
incumbent directors and simultaneously gaining control of the Board. Each
director is elected by an ordinary resolution of the annual general meeting of
our shareholders, by a vote of the holders of a majority of the voting power
represented at such meeting. Each director holds office until the annual general
meeting of our shareholders for the year in which his or her term expires and
until his or her successor has been elected. Directors who are up for election
in a given year may be removed at any time during that year by an ordinary
resolution of the general meeting of the shareholders.

                              ALTERNATE DIRECTORS

     Our Articles of Association provide that any director may appoint another
person to serve as an alternate director and may re-

                                       40
<PAGE>   45

move such alternate. Any alternate director possesses all the rights and
obligations of the director who appointed him or her, except that the alternate
has no standing at any meeting while the appointing director is present and the
alternate is not entitled to remuneration.

     Any individual, whether or not a director, may act as an alternate
director, and the same person may act as the alternate for several directors and
have a corresponding number of votes. Unless the appointing director limits the
time or scope of the appointment, the appointment is effective for all purposes
until the appointing director ceases to be a director or terminates the
appointment. The appointment of an alternate director does not in itself
diminish the responsibility of the appointing director as a director.

                             INDEPENDENT DIRECTORS

     Under Israeli law, "public" Israeli companies are required to appoint at
least two directors who meet stringent standards of independence. BackWeb
believes that this requirement does not currently apply to companies that are
publicly traded only outside of Israel. However, the new Israeli Companies Law,
which will become effective on February 1, 2000, unequivocally extends the
independent director requirement to Israeli companies that are publicly traded
outside of Israel, such as on Nasdaq. Consequently, Backweb expects to appoint
two outside directors in accordance with the new law.

                                 OFFICE HOLDERS

     Israeli law codifies the duty of care and fiduciary duties that an office
holder owes to a company. An office holder is generally a director or executive
officer. Under the Companies Ordinance, an office holder's fiduciary duty
includes avoiding any conflict of interest between the office holder's position
in BackWeb and his personal affairs, avoiding any competition with BackWeb,
avoiding exploiting any business opportunity of BackWeb in order to receive
personal advantage for himself or others and revealing to BackWeb any
information or documents relating to BackWeb's affairs which the office holder
has received due to his position as an office holder. Under Israeli law, all
arrangements as to compensation by BackWeb of office holders who are not
directors require approval of the Board of Directors.

                                AUDIT COMMITTEE

     The new Israeli Companies Law, which will become effective on February 1,
2000, provides that public companies, including Israeli companies that are
publicly traded outside of Israel, such as on Nasdaq, must appoint an audit
committee of the board of directors, a certified public accountant to audit the
company's financial statements and to report any improprieties that he or she
may discover to the chairman of the board, and an internal auditor.

                     APPROVAL OF RELATED PARTY TRANSACTIONS

     Israeli law requires that transactions be approved as provided for in a
company's articles of association, and in some circumstances by the audit
committee and by the board of directors. The vote required by the audit
committee and the board of directors for approval of these matters is a majority
of the disinterested directors participating in a duly convened meeting.
Shareholder approval is also required under some circumstances.

     Israeli law requires that an office holder of a company promptly disclose
any personal interest that he may have and all related material information
known to him, in connection with any existing or proposed transaction by the
company. Once the office holder complies with these disclosure requirements, the
company may approve the transaction in accordance with the provisions of its
articles of association. If the transaction is with a third party in which the
office holder has a personal interest, the approval must confirm that the
transaction is not adverse to the company's interest. Furthermore, if the
transaction is an extraordinary transaction, in addition to any approval
stipulated by the articles of association, it also must be approved by the
company's audit committee and then by its board of directors. An extraordinary
transaction is a transaction other than in the

                                       41
<PAGE>   46

ordinary course of business, otherwise than on market terms, or that is likely
to have a material impact on the company's profitability, assets or liabilities.
Under certain circumstances, shareholder approval is required. For example,
shareholders must approve all compensation paid to directors in whatever
capacity or any transaction in which a majority of the board members have a
personal interest. An office holder with a personal interest in any matter may
not be present at any audit committee or board of directors meeting where such
matter is being approved, and may not vote.

     The new Israeli Companies Law, which will become effective on February 1,
2000, applies the same disclosure requirements to a shareholder that holds 25%
or more of the voting rights in a public company, including an Israeli company
that is publicly traded outside of Israel such as on Nasdaq. Transactions
between a public company and a 25% shareholder, or transactions in which a 25%
shareholder of the company has a personal interest but which are between a
public company and another entity, require the approval of the board of
directors and of the shareholders. Moreover, an extraordinary transaction with a
25% shareholder or the terms of compensation of a 25% shareholder must be
approved by the audit committee, the board of directors and shareholders. The
shareholder approval for an extraordinary transaction must include at least one
third of the shareholders who have no personal interest in the transaction and
are present at the meeting. However, the transaction can be approved by
shareholders without this one third approval, if the total share holdings of
those who vote against the transaction do not represent more than one percent of
the voting rights in the company.

     For information concerning the direct and indirect personal interests of
certain office holders and principal shareholders of BackWeb in related party
transactions with BackWeb, see "Related Party Transactions."

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Israeli law permits a company to insure an office holder in respect of
liabilities incurred by him as a result of the breach of his/her duty of care to
the company or to another person, or as a result of the breach of his fiduciary
duty to the company, to the extent that he/she acted in good faith and had
reasonable cause to believe that the act would not prejudice the company. A
company can also insure an office holder for monetary liabilities as a result of
an act or omission that he/she committed in connection with his/her serving as
an office holder. Furthermore, a company can indemnify an office holder for
monetary liability in connection with his/her activities as an office holder.

     Our articles of association allow us to insure and indemnify office holders
to the fullest extent permitted by law. We have acquired directors' and
officers' liability insurance covering our officers and directors and our
subsidiaries for certain claims.

                     COMPENSATION OF OFFICERS AND DIRECTORS

     Directors do not receive cash compensation from BackWeb for services they
provide as directors, although they are reimbursed for certain expenses in
connection with attendance at board and committee meetings. From time to time,
certain directors who are not employees of BackWeb may receive grants of options
to purchase BackWeb's ordinary shares.

     The aggregate compensation paid to or accrued on behalf of the eight
directors and executive officers of BackWeb as a group during 1998 was
approximately $406,000 in salary and loans and $8,200 in amounts set aside or
accrued to provide pension, retirement or similar benefits, but excluding
amounts expended by BackWeb for automobiles made available to all of its
officers, expenses reimbursed to officers and other fringe benefits commonly
reimbursed or paid by companies in Israel. As of March 31, 1999, the eight
current directors and executive officers of BackWeb held options to purchase an
aggregate of 659,125 ordinary shares and 805,000 ordinary shares subject to a
repurchase option granted in favor of BackWeb.

                                  OPTION PLANS

     We maintain three option plans, a 1996 Israeli Option Plan, a 1996 U.S.
Option Plan and a 1998 U.S. Option Plan.

     An aggregate of approximately 10.3 million shares have been reserved under
the 1996 Israeli Option Plan, the 1996 U.S. Option Plan and the 1998 U.S. Option
Plan, including those options already exercised. Under these plans, in 1997 and
1998, options to purchase 1,890,367 and 3,236,500 ordinary shares were granted
at exercise prices ranging from $1.05 to $2.10 per share and 3,385,200 and
5,304,466 were outstanding at each respective year end. In the three months
ended March 31, 1999, options to purchase 1,088,722 ordinary shares were granted
and 4,946,980 options to purchase ordinary shares were outstanding and 3,646,344
options remained available for future grant as of March 31, 1999. The options
granted generally vest over a four-year period from the date of the grant.

     1996 ISRAELI OPTION PLAN

     Under our Israeli Option Plan, options exercisable for ordinary shares may
be granted to employees, officers, directors and consultants of BackWeb or any
other member of the BRM group. The exercise price of options granted under the
Israeli Option Plan may not be less than the nominal value of the shares into
which such option is exercisable. Each option granted under the Israeli Option
Plan may expire no later than seven years from the date of the grant. Options
granted under the Israeli Option Plan generally vest over a four-year period.

     1996 U.S. OPTION PLAN

     Under our 1996 U.S. Option Plan incentive stock options exercisable for
ordinary shares have been granted only to employees, and nonstatutory stock
options may be granted to employees, officers, directors and consultants of
BackWeb and any other members of the BRM group. The 1996 U.S. Option Plan may be
administered by the Board or a committee designated by the Board. BackWeb is no
longer granting options under the 1996 U.S. Option Plan.

     Options granted under the 1996 U.S. Plan generally vest over a four-year
period. Each option granted under the 1996 U.S. Plan may expire not later than
seven years from the date of the grant. The Board may amend or modify the plan
in all respects, except that no amendment or modification shall adversely affect
the rights of plan participants. In the event of a merger or sale all options
will be assumed by the successor corporation or fully vested for a period of 15
days, after which the options will expire. The 1996 U.S. Option Plan will
terminate on November 1, 2006, unless terminated earlier in accordance with its
provisions.

1998 U.S. OPTION PLAN

     Our 1998 U.S. Option Plan provides for the grant of incentive stock options
to employees and nonstatutory stock options and share purchase rights to
employees, directors and consultants. The number of shares reserved for issuance
under this plan will be subject to an annual increase on each anniversary
beginning July 1, 2000 equal to the lesser of (a) 1,400,000 shares, (b) 3% of
the outstanding shares on such date or (c) an amount determined by the Board.
The 1998 U.S. Option Plan is currently administered by the Board of Directors,
although the Board may designate certain committees to administer the 1998 U.S.
Option Plan with respect to different groups of service providers.

     Options and share purchase rights granted under the 1998 U.S. Option Plan
will vest as determined by the relevant administrator, and if not assumed or
substituted by a successor corporation will accelerate and become fully vested
in the event of an acquisition of BackWeb. The exercise price of options and
share purchase rights granted under the 1998 U.S. Option Plan will be as
determined by the relevant administrator, although the exercise price of
incentive stock options must be at least equal to the fair market value of our
ordinary shares on the date of grant. Options granted under the 1998 U.S. Option
Plan generally vest over a four-year period. The Board of Directors may amend,
modify or terminate the 1998 U.S. Option Plan at any time as long as such
amendment, modification or termination does not impair vesting rights of plan
participants.

                                       43
<PAGE>   48

The 1998 U.S. Option Plan will terminate in 2008, unless terminated earlier by
the Board of Directors.

     1999 EMPLOYEE STOCK PURCHASE PLAN

Our 1999 Employee Stock Purchase Plan, or the Purchase Plan, provides our
employees with an opportunity to purchase our ordinary shares through
accumulated payroll deductions. A total of 600,000 ordinary shares have been
reserved for issuance under the Purchase Plan, none of which have been issued.
The number of shares reserved for issuance under the Purchase Plan will be
subject to an annual increase on each anniversary beginning July 1, 2000 equal
to the lesser of (a) 833,333 shares, (b) 2% of the outstanding shares on such
date or (c) an amount determined by the Board. The Purchase Plan will be
administered by the Board of Directors or by a committee appointed by the Board.
The Purchase Plan permits eligible employees to purchase ordinary shares through
payroll deductions of up to 15% of an employee's compensation, up to a maximum
of $25,000 for all purchases ending within the same calendar year. Employees are
eligible to participate if they are employed by BackWeb for at least 20 hours
per week and more than five months in any calendar year. Unless the Board of
Directors or its committee determines otherwise, each offering period will run
for six months. The first offering period will commence on the date of this
prospectus and will continue until February 29, 2000, and new offering periods
will commence on each March 1 and September 1 thereafter. In the event of an
acquisition of BackWeb, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation. In the event that
the successor corporation refuses to assume or substitute for the option, the
offering period then in progress will be shortened by setting a new exercise
date. The price at which ordinary shares will be purchased under the Purchase
Plan is equal to 85% of the fair market value of the ordinary shares on the
first or last day of the applicable offering period, whichever is lower.
Employees may end their participation in the offering period at any time, and
participation automatically ends on termination of employment. Generally, the
Board may amend, modify or terminate the Purchase Plan at any time as long as
such amendment, modification or termination does not impair the rights of plan
participants. The Purchase Plan will terminate in 2009, unless terminated
earlier in accordance with its provisions.

                           RELATED PARTY TRANSACTIONS

                             RELATIONSHIP WITH BRM

     In 1995, we signed an agreement with EliBarkat Holdings Ltd., a company
controlled by Eli Barkat, BackWeb's Chairman of the Board and Chief Executive
Officer, NirBarkat Holdings Ltd., a company controlled by Nir Barkat, BackWeb's
former Chairman of the Board, and Yuval 63 Holdings (1995) Ltd., a company
controlled by Yuval Rakavy, a former director of BackWeb. In accordance with the
terms of this agreement, these three companies loaned BackWeb an aggregate of
$500,000. The loan is denominated in NIS and is payable at a rate of 2.5% of
cumulative consolidated revenues in excess of $5,000,000.

     Eli Barkat, Nir Barkat and Yuval Rakavy historically have provided BackWeb
with management and administrative services, through companies controlled by
them in return for fees and reimbursement of expenses. Aggregate amounts
incurred for these services were approximately $540,000, $516,000, $220,000 and
$24,000 during the years ended December 31, 1996, 1997, 1998 and the three
months ended March 31, 1999. Effective September 30, 1996, $748,000 of accounts
payable to the three companies for their services were converted into a loan
with terms substantially similar to those of the $500,000 loan.

     As of September 1998, Eli Barkat became a full-time employee of BackWeb and
began to receive his full compensation as an officer from BackWeb. As of March
1999, BackWeb terminated its service arrangements with the companies controlled
by Nir Barkat and Yuval Rakavy. As of March 31, 1999, $927,000 remained
outstanding under the two loans after reflecting currency conversion adjustments
and repayment.

     BackWeb historically has paid to BRM Technologies Ltd., a company
controlled by Eli Barkat, Nir Barkat and Yuval Rakavy through their holding
companies, fees for research and development services on the basis of cost plus
15% and expenses at cost. Amounts incurred for these services were approximately
$1.6 million, $1.2 million and $873,000 during the years ended December 31,
1996, 1997 and 1998 and $67,000 during the three months ended March 31, 1999.
Currently, BackWeb is reducing its use of these services and expects that
amounts payable in connection with these services will be immaterial beginning
in the second quarter of 1999.

     BackWeb has exclusive ownership of all technology developed by BRM
Technology Ltd. for BackWeb and by BRM Technology Ltd.'s employees contracted to
BackWeb.

     EliBarkat Holdings Ltd., NirBarkat Holdings Ltd. and Yuval 63 Holdings
(1995) Ltd. agreed that in connection with our Series A Preferred Stock
financing they would:

     - purchase shares of our Series A Preferred Stock; and

     - forego their right to acquire additional shares of our Series A Preferred
       Stock in exchange for the right to designate employees and consultants of
       BRM Technologies Ltd. as beneficiaries of options to acquire up to
       792,167 ordinary shares of BackWeb, all of which have been granted.

                          RELATIONSHIP WITH AFFILIATE

     We currently are negotiating the terms of a letter of intent with a newly
formed company relating to a nonexclusive license arrangement from us, as
licensor, to this newly formed company, as licensee. This license arrangement
would include a license to our technology enabling the licensee to provide a
directory of community rooms for publishing, sharing and delivery of digital
data among individuals over the Internet in exchange for license fees to be
determined on an arm's length basis. As part of the license arrangement, we
likely would receive approximately 30% of the outstanding capital stock of the
licensee.

     Three of our major shareholders, NirBarkat Holdings Ltd., EliBarkat
Holdings Ltd., and Yuval (63) Rakavy Holdings (1995) Ltd. and BARE LLC, a
company controlled by Charles Federman, one of our directors, will hold, in the
aggregate, approximately 70% of the outstanding capital stock of the licensee.
In addition, the board of directors of the
                                       45
<PAGE>   50

licensee will consist of one director nominated by us, two directors nominated
by the affiliated shareholders referred to in the preceding sentence, one
director who is the Chief Executive Officer of the licensee, and one director
not affiliated with BackWeb or its affiliates.

     Execution of a binding letter of intent will be subject to shareholder
approval under Israeli law.

                        SALE OF SERIES D PREFERRED STOCK

     Between December 1997 and March 1999, BackWeb sold its Series D Preferred
Stock in a series of private transactions with a number of investors, including
holding companies controlled by Eli Barkat, Nir Barkat and Yuval Rakavy, and
investment partnerships of which affiliates of The Goldman Sachs Group, L.P., an
affiliate of Goldman Sachs, lead manager of this offering, are general partners,
managing general partner or investment manager. The holding companies controlled
by Eli Barkat, Nir Barkat and Yuval Rakavy each purchased 1,619,073 shares of
Series D Preferred Stock. Upon closing of this offering, each block of 1,619,073
Series D Preferred Stock will convert into 539,691 ordinary shares. Investment
partnerships of which affiliates of The Goldman Sachs Group, L.P., an affiliate
of Goldman Sachs, lead manager of this offering, are general partners, managing
general partner or investment manager purchased 2,818,030 shares of Series D
Preferred Stock, which upon the closing of this offering converts into 939,343
ordinary shares. In January 1998, BancAmerica Robertson Stephens, an affiliate
of BancBoston Robertson Stephens Inc., one of the underwriters in this offering,
participated as the placement agent for the Series D Preferred Stock.

                         REGISTRATION RIGHTS AGREEMENT

     As of March 31, 1999, the holders of 25,685,739 ordinary shares have rights
to register those shares under the Securities Act pursuant to registration
rights agreements. Holders of these registrable shares have unlimited rights to
request that these shares be included in any BackWeb-initiated underwritten
public offering of our securities. The underwriters may reduce the registrable
shares to be included on the registration statement for marketing reasons. In
addition, at any time on or prior to the earlier of December 27, 2002 or six
months after the effective date of this prospectus, holders of a majority of the
registrable shares may demand that we register these shares up to two times.
Also, one year after we become a public reporting company, holders of
registrable shares may request that we effect a registration of these shares on
a shelf registration statement once in any twelve-month period. All expenses
incurred in connection with such registrations, other than underwriters' and
brokers' discounts and commissions, will be borne by BackWeb.

     Our authorized share capital consists of 200 million shares, NIS 0.01
nominal value per share, including 150 million ordinary shares, 50 million
preferred shares and one Series E Preferred Share. As of March 31, 1999, there
were 26,946,139 ordinary shares issued and outstanding.

                         DESCRIPTION OF ORDINARY SHARES

     All issued and outstanding ordinary shares of BackWeb are, and the ordinary
shares offered hereby when issued and paid for will be, duly authorized and
validly issued, fully paid and non-assessable. The ordinary shares do not have
preemptive rights. Neither the memorandum of association or articles of
association of BackWeb nor the laws of the State of Israel restrict in any way
the ownership or voting of ordinary shares by non-residents of Israel, except
with respect to subjects of countries which are in a state of war with Israel.

DIVIDEND AND LIQUIDATION RIGHTS

     The ordinary shares offered by this prospectus, when issued, will be
entitled to the full amount of any cash or share dividend declared from the date
of the consummation of this offering. Subject to the rights of the holders of
shares with preferential or other special rights that may be authorized, the
holders of ordinary shares are entitled to receive dividends out of legally
available assets and, in the event of the winding up of BackWeb, to share
ratably in all assets remaining after payment of liabilities, subject to
applicable law. The board of directors may declare interim dividends and
recommend a final annual dividend from retained earnings available for cash
dividends as determined for statutory purposes at such times and in such amounts
as the board of directors may determine. Declaration of the final annual
dividend requires shareholder approval at a general meeting, which may reduce
but not increase such dividend from the amount recommended by the board of
directors. See "Dividend Policy."

     In case of a share dividend, holders of shares can receive shares of a
class whether such class existed prior thereto or was created therefor or shares
of the same class that conferred upon the holders the right to receive such
dividend.

VOTING, SHAREHOLDER MEETINGS AND RESOLUTIONS

     Holders of ordinary shares have one vote for each ordinary share held on
all matters submitted to a vote of shareholders. Such rights may be affected by
the future grant of any special voting rights to the holders of a class of
shares with preferential rights. As of the closing of this offering, all of the
outstanding Series A, Series B, Series C and Series D Preferred Shares will be
converted into ordinary shares, and there will be no shares outstanding with
preferential rights over the ordinary shares. Any change in the registered
capital of BackWeb, which does not include the issuance of registered but
unissued shares, including the creation of a new class of shares with rights
superior or inferior to existing classes of shares may be adopted by a "special
resolution." A special resolution is the resolution of the holders of 75% or
more of the shares participating in a general meeting.

     An annual general meeting shall be held once every calendar year at such
time, but not later than 15 months after the last annual general meeting, and at
such place, either within or outside of the State of Israel, as may be
determined by the board of directors. The quorum required for a general meeting
of shareholders consists of at least two shareholders present in person or by
proxy and holding, or representing, more than fifty percent of the voting rights
of the issued share
                                       49

capital. A meeting adjourned for lack of a quorum may be adjourned to the same
day in the next week at the same time and place, or to such time and place as
the chairman of the meeting may determine with the consent of the holders of a
majority of the shares present in person or by proxy and voting on the question
of adjournment. At such adjourned meeting, any two shareholders present in
person or by proxy will constitute a quorum.

     Most shareholder resolutions, including resolutions for the election of
directors, the declaration of dividends, the appointment of auditors or the
approval of transactions with office holders as required by the Companies
Ordinance will be deemed adopted if approved by the holders of a majority of the
voting power represented at the meeting, in person or by proxy, and voting
thereon. See "Management -- Approval of Certain Transactions." Certain corporate
actions such as:

     - amending the articles of association;

     - amending the memorandum of association;

     - changing our name;

     - making changes in our capital structure such as a reduction of capital,
       increase of capital or share split;

     - merger or consolidation;

     - voluntary winding up; and

     - authorizing a new class of shares or changing special rights of a class
       of shares.

     Upon completion of this offering, our executive officers, directors and 10%
or greater shareholders will own beneficially an aggregate of approximately
44.2% of our outstanding ordinary shares, including 2,595,501 ordinary shares
issuable upon exchange of BackWeb Canada, Inc. exchangeable shares, or
approximately 43.2% if the underwriters' over-allotment option is exercised in
full. See "Principal Shareholders."

TRANSFER OF SHARES AND NOTICES

     Fully paid ordinary shares are issued in registered form and may be
transferred freely. Each shareholder of record is entitled to receive at least 7
days' prior notice of shareholder meetings. A special resolution can be adopted
only if shareholders are given 21 days' prior notice of the meeting at which
such resolution will be voted on, unless all shareholders entitled to vote agree
that the meeting may be held on a shorter notice period. For purposes of
determining the shareholders entitled to notice and to vote at such meeting, the
board of directors may fix the record date not less than 24 days prior to the
date of a meeting at which a special resolution is to be submitted for vote, and
not less than ten days prior to the date of any other meeting.

MODIFICATION OF CLASS RIGHTS

     If at any time the share capital is divided into different classes of
shares, the rights attached to any class, unless otherwise provided by our
articles of association, may be modified or abrogated by BackWeb by a special
resolution subject to the consent in writing of the holders of the issued shares
of the class, or with the adoption of a special resolution passed at a separate
general meeting of the holders of the shares of such class.

                         DESCRIPTION OF PREFERRED STOCK

     BackWeb has one share of Series E Preferred Stock outstanding. In
connection with our acquisition of Lanacom, Inc., a Canadian company, in August
1997, we are obligated to issue to the former Lanacom shareholders an aggregate
of 2,595,501 ordinary shares in exchange for the exchangeable shares in BackWeb
Canada held by the former Lanacom shareholders at any time, at the election of
the holders thereof, into our ordinary shares. The share of Series E Preferred
Stock was issued to a trustee for the former Lanacom shareholders pursuant to a
Voting and Exchange Trust Agreement. Under this agreement, the exchangeable
shareholders are entitled to exercise voting rights equivalent to voting rights
attaching to the same number of ordinary shares by and through the trustee of
the share of Series E Preferred Stock. The share of Series E Preferred Stock
will be canceled at such time that no exchangeable shares are held by the
                                       50
<PAGE>   55

former Lanacom shareholders. The exchangeable share structure is a common tax-
advantageous structure used in acquisitions of Canadian companies.

     BackWeb has an additional 50 million preferred shares authorized. The board
of directors has the authority to issue the preferred shares without further
vote or action by the shareholders in one or more series and to fix the rights,
preferences, privileges and restrictions of the preferred shares, including
dividend rights, dividend rates, conversion rights, voting rights, terms of
redemption, redemption prices, liquidation preferences and the number of shares
constituting any series. If the board of directors issues preferred shares, this
may delay, defer or prevent a change in control of BackWeb without further
action by the shareholders. For example, the board of directors could issue
preferred shares that have the power to prevent a change of control transaction.
The issuance of preferred shares with voting and conversion rights may adversely
affect the voting power of the holders of ordinary shares, including the loss of
voting control to others. BackWeb currently has no plans to issue any of the
unissued preferred shares.

                              OPTIONS AND WARRANTS

     As of March 31, 1999, options to purchase 4,946,980 ordinary shares were
outstanding. These outstanding options are subject to the 1996 Israeli Option
Plan, 1996 U.S. Option Plan or 1998 U.S. Option Plan. See "Management -- Option
Plans." BackWeb has also issued warrants to purchase an aggregate of 145,726
ordinary shares at a weighted exercise price of $3.45 per share.

                              REGISTRATION RIGHTS

     As of March 31, 1999, the holders of 25,685,739 ordinary shares have rights
to register those shares under the Securities Act pursuant to registration
rights agreements. Holders of these registrable shares have unlimited rights to
request that these shares be included in any BackWeb-initiated underwritten
public offering of our securities. The underwriters may reduce the registrable
shares to be included on the registration statement for marketing reasons. In
addition, at any time the earlier of December 27, 2002 or six months after the
effective date of this prospectus, holders of a majority of the registrable
shares may demand that we register these shares up to two times. Also, one year
after we become a public reporting company, holders of registrable shares may
request that we effect a registration of these shares on a shelf registration
statement once in any twelve-month period. In addition, we have agreed to
register the resale of the ordinary shares issuable upon the exchange of the
exchangeable shares held by the former shareholders of Lanacom, Inc., on the
180th day after the date of this prospectus and thereafter. All expenses
incurred in connection with such registrations, other than underwriters' and
brokers' discounts and commissions, will be borne by BackWeb.

                     ANTI-TAKEOVER EFFECTS OF ISRAELI LAWS

     The Israeli Companies Ordinance, which governs Israeli corporations, does
not contain provisions that deal specifically with a merger that allows for the
elimination of minority shareholders. Provisions that deal with "arrangements"
between a company and its shareholders have been used, however, to effect
squeeze-out mergers. These provisions generally require that the merger be
approved by at least 75% of the shareholders present and voting on the proposed
merger, at a shareholders meeting that has been called on at least 21 days'
advance notice. In addition to shareholder approval, court approval of the
merger is required, which entails further delay and may entail the imposition of
additional requirements at the court's discretion. Alternatively, the acquiror
can eliminate minority shareholders if it acquires at least 90% of all
outstanding shares, excluding shares held by the acquiror prior to the
acquisition, and none of the minority shareholders seeks to block the
acquisition in court. The new Israeli Companies Law that will come into effect
on February 1, 2000, does address squeeze-out mergers but does not significantly
modify these requirements.

     The new Companies Law also provides that an acquisition of shares in a
public company must be made by means of a tender

                                       51
<PAGE>   56

offer if as a result of the acquisition the purchaser would become a 25%
shareholder of the company. This rule does not apply if there is already another
25% shareholder of the company. Similarly, the new Companies Law provides that
an acquisition of shares in a public company must be made by means of a tender
offer if as a result of the acquisition the purchaser would become a 45%
shareholder of the company. This rule does not apply if someone else is already
a majority shareholder of the company. Since regulations implementing these new
rules have not yet been promulgated, we do not know to what extent or how these
rules will apply to Israeli companies that are publicly traded outside of
Israel. Finally, Israeli tax law treats certain acquisitions, particularly
stock-for-stock swaps between an Israeli company and a foreign company, less
favorably than United States tax law. Israeli tax law may, for instance, subject
a shareholder who exchanges his BackWeb shares for shares in a foreign
corporation to immediate taxation.

                             ACCESS TO INFORMATION

     We file reports with the Israeli Registrar of Companies regarding our
registered address, our registered capital, our shareholders of record and the
number of shares held by each, the identity of the directors and details
regarding security interests on our assets. In addition, we must file with the
Registrar of Companies our articles of association and a copy of any special
resolution adopted by a general meeting of shareholders. The information filed
with the Registrar of Companies is available to the public. In addition to the
information available to the public, our shareholders are entitled, upon
request, to review and receive copies of all minutes of meetings of our
shareholders.

                          TRANSFER AGENT AND REGISTRAR

     BackWeb has appointed American Stock Transfer and Trust Company as the
transfer agent and registrar for the ordinary shares.

                        SHARES ELIGIBLE FOR FUTURE SALE

     If our shareholders sell substantial amounts of our ordinary shares,
including shares issued upon the exercise of outstanding options and warrants,
in the public market following this offering, the market price of our ordinary
shares could fall dramatically. These sales also might make it more difficult
for us to sell equity or equity-related securities in the future at a time and
price that we deem appropriate.

     The number of ordinary shares available for sale in the public market is
limited by restrictions under federal securities law and by certain "lock-up"
agreements that our shareholders have entered into with the underwriters. The
lock-up agreements restrict our shareholders from selling or otherwise disposing
of any of their shares for a period of 180 days after the date of this
prospectus without the prior written consent of Goldman Sachs. Goldman Sachs
may, however, in its sole discretion and without notice, release all or any
portion of the shares from the restrictions in the lock-up agreements.

     Upon completion of this offering, we will have outstanding 32,446,139
ordinary shares, based upon shares outstanding as of March 31, 1999. Of these
shares, the 5,500,000 shares sold in this offering are freely tradable. This
leaves 26,946,139 shares eligible for sale in the public market as follows:

     Any ordinary shares that may be purchased in this offering by our
"affiliates," as defined in Rule 144 of the Securities Act, will be subject to
the volume and other selling limitations under Rule 144 of the Securities Act.
All but 5,762,820 of the shares eligible for sale at the 180th day after the
date of this prospectus or afterward will be subject initially to certain volume
and other limitations under Rule 144 of the Securities Act.

     In addition, upon completion of the offering we will have 2,595,501
ordinary shares that are issuable at any time for no additional consideration
upon exchange of the BackWeb Canada exchangeable shares issued to the former
shareholders of Lanacom in connection with our acquisition of Lanacom.

     Moreover, on or prior to the 180th day following the date of this
prospectus, we intend to register for resale approximately 10.9 million ordinary
shares reserved for issuance or issued under our employee stock plans.

     The holders of approximately 25,685,739 ordinary shares have the right to
require us to register their shares for sale to the public. In addition, we have
agreed to register the resale of the ordinary shares issuable upon the exchange
of the exchangeable shares held by the former shareholders of Lanacom, Inc., on
the 180th day after the date of this prospectus and thereafter. If these holders
cause a large number of shares to be registered and sold in the public market,
our stock price could fall materially.

            MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following summary describes the material United States federal income
tax consequences relating to an investment in ordinary shares as of the date
hereof. The summary is based on the Internal Revenue Code of 1986, and existing
final, temporary and proposed Treasury Regulations, Rulings and judicial
decisions, all of which are subject to prospective and retroactive changes. We
will not seek a ruling from the Internal Revenue Service, or the IRS, with
regard to the United States federal income tax treatment relating to investment
in ordinary shares and, therefore, there can be no assurance that the IRS will
agree with the conclusions set forth below. The summary does not purport to
address all federal income tax consequences that may be relevant to a particular
investor and you may want to consult your own tax advisor regarding your
specific tax situation. For example, the summary applies only to holders who
hold ordinary shares as a capital asset within the meaning of Section 1221 of
the Code, and does not address the tax consequences that may be relevant to
investors in special tax situations including, for example:

     - insurance companies,

     - tax-exempt organizations,

     - dealers in securities or currency,

     - banks or other financial institutions,

     - investors that hold ordinary shares as part of a hedge, straddle or
       conversion transaction, or

     - holders that own, directly or indirectly, ten percent or more of our
       outstanding ordinary shares.

Further, it does not address the alternative minimum tax consequences of an
investment in ordinary shares or the indirect consequences to holders of equity
interests in entities that own ordinary shares. In addition, this summary does
not address the state, local and foreign tax consequences of an investment on
the ordinary shares.

     For purposes of this discussion, "U.S. holder" means a holder of ordinary
shares that is:

     - a citizen or resident of the United States,

     - a partnership or corporation created or organized in or under the laws of
       the United States or any State thereof, including the District of
       Columbia,

     - an estate, the income of which is subject to United States federal income
       tax regardless of its source or a trust if (a) a court within the United
       States is able to exercise primary supervision over its administration
       and (b) one or more United States persons have the authority to control
       all substantial decisions of the trusts.

     The term "non-U.S. holder" refers to any holder of ordinary shares other
than a U.S. holder.

                            TAXATION OF U.S. HOLDERS

DISTRIBUTIONS ON ORDINARY SHARES

     Distributions made by us with respect to ordinary shares generally will
constitute foreign source dividends for federal income tax purposes. These
distributions will be taxable to a U.S. holder as ordinary income to the extent
of our undistributed current or accumulated earnings and profits (as determined
for United States federal income tax purposes). Distributions in excess of
current or accumulated earnings and profits will be treated first as a
non-taxable return of capital which will reduce the U.S. holder's tax basis in
the ordinary shares. Any such distributions in excess of a U.S. holder's tax
basis in the ordinary shares will be treated as capital gain to the U.S. holder
and will be either long-term or short-term capital gain depending upon the U.S.
holder's federal income tax holding period for the ordinary shares.

     Dividends paid by us generally will not be eligible for the dividends
received deduction available to certain United States corporate shareholders
under Code Sections 243 and 245.

     The amount of any cash distribution paid in a foreign currency will equal
the U.S. dollar value of the distribution, calculated by refer-

                                       54
<PAGE>   59

ence to the exchange rate in effect at the time the dividends are received. A
U.S. holder should not recognize any foreign currency gain or loss if such
foreign currency is converted into U.S. dollars on the day received. If a U.S.
holder does not convert the foreign currency into U.S. dollars on the date of
receipt, however, such holder may recognize gain or loss upon a subsequent sale
or other disposition of the foreign currency (including an exchange of the
foreign currency for U.S. dollars). Such foreign currency gain or loss, if any,
will be U.S. source ordinary income or loss for United States federal income tax
purposes.

     Subject to certain conditions and limitations, any Israeli withholding tax
imposed upon distributions under United States income tax law will be eligible
for credit against a U.S. holder's federal income tax liability. Alternatively,
a U.S. holder may claim a deduction for such amount, but only for a year in
which a U.S. holder elects to do so with respect to all foreign income taxes.
The overall limitation on foreign taxes eligible for credit is calculated
separately with respect to specific classes of income. For this purpose,
dividends distributed by us with respect to ordinary shares will generally
constitute foreign source "passive income."

SALE OR EXCHANGE OF ORDINARY SHARES

     A U.S. holder of ordinary shares generally will recognize capital gain or
loss upon the sale or exchange of the ordinary shares measured by the difference
between the amount realized and the U.S. holder's tax basis in the ordinary
shares. Gain or loss will be computed separately for each block of shares sold
(shares acquired separately at different times and prices). The gain or loss on
such disposition will be long term-capital gain or loss if the ordinary shares
had been held for more than one year. In general, any capital gain or loss
recognized by a U.S. holder upon the sale or exchange of ordinary shares will be
treated as United States source income or loss, as the case may be, for United
States foreign tax credit purposes. The deductibility of capital losses is
restricted and generally may only be used to reduce capital gains to the extent
thereof. However, individual taxpayers generally may deduct annually $3,000 of
capital losses in excess of their capital gains.

PASSIVE FOREIGN INVESTMENT COMPANY

     A foreign corporation generally will be treated as a "passive foreign
investment company," or PFIC, if, after applying certain "look-through" rules,
either

     - 75% or more of its gross income for the taxable year is passive income or

     - on average for the taxable year (by value or, if BackWeb so elects, by
       adjusted basis) 50% or more of its assets produce or are held for the
       production of passive income.

     Passive income for this purpose generally includes:

     - dividends

     - interest

     - rents

     - royalties and the excess of gains over losses from securities and
       commodities transactions

     The look-through rules provide in part that a foreign corporation that owns
at least 25%, by value, of an operating subsidiary will treat that proportion of
the subsidiaries assets and income as held or received directly by the foreign
parent.

     We believe that we were not a PFIC as of December 31, 1998, and do not
anticipate that we will be a PFIC in the future because we expect that less than
75% of our annual gross income will be passive income and less than 50% of our
assets will be passive assets, based on the look-through rules, our current
income and assets and the manner in which we anticipate conducting our
businesses in the future. We do not believe we were a PFIC at the end of our
last fiscal year based upon our determination of our income and assets. However,
there can be no assurance that we are not or will not be treated as a PFIC in
the future.

     If we were to be treated as a PFIC, all U.S. holders may be required, in
certain

                                       55
<PAGE>   60

circumstances, to pay an interest charge together with tax calculated at maximum
rates on certain "excess distributions," including any gain on the sale of
ordinary shares. In order to avoid this tax consequence, a U.S. holder

     - may be permitted to make a "qualified electing fund" election, in which
       case, in lieu of the treatment described in the previous sentence, the
       U.S. holder would be required to include in its taxable income certain
       undistributed amounts of our income or

     - may elect to mark-to-market the ordinary shares and recognize ordinary
       income (or possible ordinary loss) each year with respect to such
       investment and on the sale or other disposition of the ordinary shares.

     Neither we nor our advisors has the duty to, or will undertake to inform,
U.S. holders of changes in circumstances that would cause us to become a PFIC.
U.S. holders should consult their own tax advisors concerning our status as a
PFIC at any time after the date of this Prospectus. We do not currently intend
to take the action necessary for a U.S. holder to make a "qualified electing
fund" election in the event we are determined to be a PFIC.

FOREIGN PERSONAL HOLDING COMPANY

     A foreign corporation may be classified as a foreign personal holding
company, or FPHC, for federal income tax purposes if both of the following tests
are satisfied:

     - at any time during the taxable year five or fewer individuals who are
       United States citizens or residents own or are deemed to own, under
       certain attribution rules, more than 50% of its stock, by vote or value,
       and

     - at least 60%, 50% for years subsequent to the year in which it becomes a
       FPHC, of its gross income regardless of its source, as specifically
       adjusted, "is foreign personal holding company income," which includes
       dividends, interest, rents, royalties and gain from the sale of stock or
       securities.

     We do not believe that we are currently a FPHC nor do we anticipate that we
will be a FPHC in the future. However, no assurance can be given that we are not
or will not become a FPHC as a result of future changes of ownership or changes
in the nature of the income of BackWeb. If we were to be classified as a FPHC,
each U.S. holder would be required to include in income as a taxable
constructive dividend its pro rata share of our undistributed foreign personal
holding company income.

                          TAXATION OF NON-U.S. HOLDERS

DISTRIBUTIONS ON ORDINARY SHARES

     In general, distributions by us to non-U.S. holders who are not engaged in
the conduct of a trade or business within the United States will be subject to
United States federal income tax only if 25% or more of our gross income, from
all sources for the three-year period ending with the close of the taxable year
preceding the declaration of the distribution, was effectively connected with
our conduct of a trade or business in the United States. We do not anticipate
engaging in the conduct of a trade or business within the United States, except
through our subsidiaries. However, if the 25% threshold for such period is
exceeded, a portion of any distribution paid by us to a non-U.S. holder may be
subject to federal income tax withholding at the rate of 30%. The portion of the
distribution that may be subject to withholding will generally correspond to the
portion of our gross income for the period that is effectively connected to the
conduct of a trade or business within the United States.

SALE OR EXCHANGE OF ORDINARY SHARES

     Non-U.S. holders will not be subject to United States federal income tax on
any gain realized upon the sale or exchange of ordinary shares, unless

      (i) such gain is effectively connected with a United States trade or
          business of the non-U.S. holder or,

     (ii) in the case of gain recognized by an individual non-U.S. holder, such
          individual is present in the United States for 183 days or more during
          the taxable year of disposition and certain other conditions are
          satisfied.

                                       56
<PAGE>   61

UNITED STATES TRADE OR BUSINESS

     A non-U.S. holder engaged in a trade or business in the United States whose
income from the ordinary shares (including gain from the sale or exchange
thereof) is effectively connected with the conduct of such trade or business
will generally be subject to regular United States federal income tax on such
income in the same manner as if it were a U.S. Holder. In addition, if such a
holder is a foreign corporation, it may be subject to a branch profits tax equal
to 30% of its effectively connected earnings and profits for the taxable year,
subject to adjustments.

                               BACKUP WITHHOLDING

     Distributions made by us with respect to the ordinary shares and gross
proceeds received from the disposition of the ordinary shares may be subject to
certain information reporting requirements to the IRS and to a 31% backup
withholding tax. However, backup withholding generally will not apply to
payments made to certain exempt recipients such as a corporation or financial
institution or to a holder who furnishes a correct taxpayer identification
number or provides a certificate of foreign status and provides certain other
required information. If backup withholding applies, the amount withheld is not
an additional tax, but is credited against such holder's United States federal
income tax liability.

                    ISRAELI TAXATION AND INVESTMENT PROGRAMS

     The following is a summary of the current tax laws of the state of Israel
as they relate to BackWeb and our shareholders. This summary does not discuss
all aspects of Israeli tax law that may be relevant to a particular investor in
light of his personal investment circumstances or to certain types of investor
subject to special treatment under Israeli law. The following also includes a
discussion of certain Israeli government programs benefiting various Israeli
businesses such as BackWeb. To the extent that the discussion is based on new
legislation yet to be subject to judicial or administrative interpretation,
there can be no assurance that the views expressed herein will accord with any
such interpretation in the future. This discussion is not intended and should
not be construed as legal or professional tax advice, and does not cover all
possible tax considerations.

                        GENERAL CORPORATE TAX STRUCTURE

     The general corporate tax rate in Israel is 36%. However, the effective tax
rate payable by a Company which derives income from an "Approved Enterprise" may
be considerably lower. See "-- Law for the Encouragement of Capital Investments,
1959."

     BackWeb's tax loss carry-forwards were approximately $30.0 million as of
December 31, 1998. The amount of BackWeb's tax loss carry-forwards will be
reduced by any future income of BackWeb that would be fully tax-exempt for a
defined period.

                     TAXATION UNDER INFLATIONARY CONDITIONS

     The income Tax Law (Adjustment for Inflation), 1985 attempts to overcome
some of the problems experienced in a traditional tax system by an economy
experiencing rapid inflation, which was the case in Israel at the time the
Adjustment for Inflation Law was enacted. Generally, the Adjustment for
Inflation Law was designed to neutralize for Israeli tax purposes the erosion of
capital investments in businesses and to prevent unintended tax benefits
resulting from the deduction of inflationary financing expenses. The Adjustment
for Inflation Law applies a supplementary set of inflationary adjustments to a
normal taxable profit computed according to regular historical cost principles.

     The Adjustment for Inflation Law introduced a special tax adjustment for
the preservation of equity based on changes in the Israeli consumer price index,
or CPI, whereby certain corporate assets are classified broadly into fixed
(inflation resistant) assets and non-fixed assets. Where shareholders' equity,
as defined in the Adjustment for Inflation Law exceeds the depreciated cost of
fixed assets, a corporate tax deduction which takes into account the effect of
the applicable annual rate of inflation on such excess is allowed, up to a
ceiling of 70% of taxable income for companies in any single tax year, with the
unused portion permitted to be carried forward on a linked basis with no
ceiling. If the depreciated cost of fixed assets exceeds shareholders' equity,
then such excess multiplied by the applicable annual rate of inflation is added
to taxable income.

     In addition, subject to certain limitations depreciation deductions on
fixed assets and losses carried forward are adjusted for inflation based on
changes in the Israeli CPI. The net effect of the Adjustment for Inflation Law
on BackWeb might be that our taxable income, as determined for Israeli corporate
tax purposes, will be different than our U.S. dollar income, as reflected in its
financial statements, due to the difference between the annual changes in the
Israeli CPI and in the NIS exchange rate with respect to the U.S. Dollar,
causing changes in the actual tax rate.

              LAW FOR THE ENCOURAGEMENT OF INDUSTRY (TAXES), 1969

     We currently qualify as an "Industrial Company" within the definition of
the Law for the Encouragement of Industry (Taxes), 1969, or the Industry
Encouragement Law. According to the Industry Encouragement Law, an "Industrial
Company" is a company resident in Israel, at least 90% of the income of which in
any tax year determined in Israeli currency exclusive of income from defense
loans, capital gains, interest and dividends, is derived from an "Industrial
Enterprise" owned by it. An "Industrial Enterprise" is defined by
                                       58
<PAGE>   63

that law as an enterprise whose major activity in a given tax year is industrial
production activity.

     Tax benefits for an Industrial Company include deductions of 12.5% per
annum of the purchase price of a good faith acquisition of a patent or of
know-how, an election under some conditions to file a consolidated tax return
with additional related Israeli Industrial Companies and accelerated
depreciation rates on equipment and buildings.

     Eligibility for the benefits under the Industry Encouragement Law is not
subject to receipt of prior approval from any governmental authority. We cannot
assure you that we will continue to qualify as an "Industrial Company" or that
the benefits described above will be available in the future.

             LAW FOR THE ENCOURAGEMENT OF CAPITAL INVESTMENTS, 1959

     The Law for the Encouragement of Capital Investments, 1959, as amended, or
the Investment Law, provides that a capital investment in eligible facilities
may, upon application to the Israeli Investment Center, be designated as an
Approved Enterprise. Each certificate of approval for an Approved Enterprise
relates to specific program delineated both by its financial scope, including
its capital sources, and by its physical characteristics, i.e., the equipment to
be purchased and utilized pursuant to the program. The tax benefits derived from
any such certificate of approval relate only to taxable income attributable to
the specific Approved Enterprise.

     BackWeb's investment program has been granted the status of an "Approved
Enterprise" under the Investment Law. As of December 31, 1998, the Investment
Program had not been completed.

     In the event a company operates under more than one approval, or only part
of its capital investments are approved, or it generates income from sources
other than its Approved Enterprise Program, its effective corporate tax rate is
the result of a weighted combination of the various applicable rates.

     According to the provisions of the Investment Law, we chose the
"Alternative Benefits Program" -- waiver of grants in return for tax exemption.
Accordingly, our income from the Approved Enterprise will be tax-exempt for a
period of two years commencing with the year we first earn taxable income, and
subject to corporate tax at the rate of 10% to 25%, for an additional period of
five to eight years depending on the percentage of the foreign investment in
BackWeb.

     This period of tax benefits is subject to a limit of 12 years from the
commencement of production, or 14 years from receiving the approval, whichever
is earlier. Under these conditions, the period of benefits for BackWeb's present
plan will terminate by the year 2009.

     If dividends are distributed out of such tax-exempt profits, we will be
liable for corporate tax at the rate which would have been applied if we had not
chosen the alternative tax benefits program (currently 25%).

     The dividend recipient is taxed at the reduced rate applicable to dividends
from Approved Enterprises (15%). This tax must be withheld by the company at
source regardless of whether the dividend is converted into foreign currency.
See "-- Capital Gains and Income Taxes Applicable to Non-Israeli Shareholders."

     The Investment Law also provides that an Approved Enterprise is entitled to
accelerated depreciation on its property and equipment that are included in an
approved investment program.

     Incentives received by a company in accordance with the Investment Law
remain subject to final ratification by the Israeli Investment Center, such
ratification being conditional upon fulfillment of all terms of the approved
program. Failure to comply with all such terms may require the return of such
incentives, inclusive of interest and penalties.

     We believe that we have operated and will continue to operate in compliance
with all the "Approved Enterprise" conditions and criteria applicable, although
there can be no assurance of this, and that the likelihood is remote that we
will be required to refund tax benefits under the "Approved Enterprise"
                                       59
<PAGE>   64

status. We cannot assure you that the tax benefits will continue.

     Future applications to the Investment Center will be reviewed separately
with approvals based upon several factors, including the prevailing criteria set
forth in the Investment Law, the specific objectives of the applicant company
and the financial criteria of the applicant company.

     CAPITAL GAINS AND INCOME TAXES APPLICABLE TO NON-ISRAELI SHAREHOLDERS

     Israeli law generally imposes a capital gains tax on the sale of securities
and any other capital asset. The basic rate applicable to corporations is
currently 36%. The maximum tax rate for individuals is 50%. These rates are
subject to the provisions of any applicable bilateral double taxation treaty,
including the double taxation treaty between the United States and Israel
discussed below.

     Under existing regulations any capital gain realized by an individual
shareholder with respect to the ordinary shares acquired on or after the
registration of such shares will be exempt from Israeli Capital Gains Tax if the
ordinary shares are listed on an approved foreign securities market, (including
the Nasdaq in the United States), and provided that (a) BackWeb continues to
qualify as an Industrial Company under Israeli law and (b) the individual does
not hold such shares for business purposes.

     We cannot assure you that we will maintain such qualification or our status
as an Industrial Company. If we do not maintain our status as an Industrial
Company, then subject to any applicable tax treaty, the applicable Israeli
capital gains tax rates would be up to 50% for non-resident individuals and for
any pre-initial public offering gains of resident individuals, 35% for
post-initial public offering gains of resident individuals and 36% for resident
and non-resident companies. Individuals who are non-residents of Israel are
subject to income tax on income derived from sources in Israel, or received in
Israel. Such sources of income include passive income such as dividends,
royalties and interests as well as non-passive income from services rendered in
Israel. Upon a distribution of dividends other than bonus shares (stock
dividends), income tax is generally withheld at source at the rate of 25%, with
a rate of 15% for dividends generated by an Approved Enterprise, unless a double
taxation treaty is in effect between Israel and the shareholders country of
residence that provides for a lower tax rate in Israel on dividends.

     A tax treaty between the United States and Israel, or the Treaty, effective
since January 1, 1995, provides for a maximum tax of 25% on dividends paid to a
resident of the United States as defined in the Treaty. Dividends distributed by
an Israeli company and derived from the income of an approved enterprise are
subject to a 15% dividend withholding tax. The Treaty further provides that a
12.5% Israeli dividend withholding tax would apply to dividends paid to a United
States corporation owning 10% or more of an Israeli Company's voting stock
during both the preceding year and the current year through the dividend payment
date. The 12.5% rate applies only on dividends from a company that does not have
an "Approved Enterprise" in the applicable period.

     Residents of the United States generally will have withholding tax in
Israel deducted at the source. They may be entitled to a credit or deduction for
U.S. federal income tax purposes in the amount of the taxes withheld, subject to
detailed rules contained in the Treaty and in U.S. tax legislation. See "United
States Federal Income Tax Considerations -- Taxation of U.S. Holders." If for
any reason shareholders do not receive the above exemption for a sale of shares
in an Industrial Company, the Treaty provides U.S. resident investors with an
exemption from Israeli capital gains tax, although there may still be U.S.
taxes, upon a disposition of shares in the Company if they held under 10% of the
Company's voting stock through the 12 months before the share disposition. If
Israeli capital gains tax is payable, it may be credited against U.S. tax in
certain circumstances under special provisions in the Treaty. Special tax rules
apply to businesses in Israel, and regular Israeli taxation will apply to
securities dealers in Israel. A non-resident of Israel who has had dividend
income derived or accrued in Israel from which tax was
                                       60
<PAGE>   65

withheld at source is currently exempt from the duty to file an annual Israeli
tax return with respect to such income, provided such income was not derived
from a business carried on in Israel by such non-resident and that such
non-resident does not derive other non-passive income from sources in Israel.
Proposals are being formulated to expand the requirement to file annual Israeli
tax returns.

                   TAX BENEFITS FOR RESEARCH AND DEVELOPMENT

     Israeli tax law allows under certain conditions a tax deduction in the year
incurred for expenditures (including non-depreciable capital expenditures) in
scientific research and development projects, if the expenditures are approved
by the relevant Israeli Government Ministry (determined by the field of
research) and the research and development is for the promotion of the
enterprise. and is carried out by or on behalf of the company seeking such
deduction. Expenditures not so approved are deductible over a three-year period.
However, according to Israeli Supreme Court decisions, expenditures made out of
the proceeds of government grants are not deductible, i.e., we will be able to
deduct the unfunded portion of the research and development expenditures and not
the gross amount.

                                       61
<PAGE>   66

                              CONDITIONS IN ISRAEL

     BackWeb is incorporated under the laws of the State of Israel, and
substantially all of our research and development and significant executive
facilities are located in Israel. Accordingly, BackWeb is directly affected by
political, economic and military conditions in Israel. Our operations would be
materially adversely affected if major hostilities involving Israel should occur
or if trade between Israel and its present trading partners should be curtailed.

                              POLITICAL CONDITIONS

     Since the establishment of the State of Israel in 1948, a number of armed
conflicts have taken place between Israel and its neighbors. A state of
hostility, varying from time to time in intensity and degree, has led to
security and economic problems for Israel. However, a peace agreement between
Israel and Egypt was signed in 1979, a peace agreement between Israel and Jordan
was signed in 1994 and, since 1993, several agreements between Israel and
Palestinian representatives have been signed. In addition, Israel and several
Arab States have announced their intention to establish trade and other
relations and are discussing certain projects. Israel has not entered into any
peace agreement with Syria or Lebanon, and there have been difficulties in the
negotiations with the Palestinians. We cannot be certain as to how the peace
process will develop or what effect it may have upon BackWeb.

     Despite the progress towards peace between Israel, its Arab neighbors and
the Palestinians, certain countries, companies and organizations continue to
participate in a boycott of Israeli firms. BackWeb does not believe that the
boycott has had a material adverse effect on BackWeb, but restrictive laws,
policies or practices directed towards Israel or Israeli businesses may have an
adverse impact on the expansion of BackWeb's business.

     Generally, all male adult citizens and permanent residents of Israel under
the age of 51 are obligated to perform up to 39 days, or longer under certain
circumstances, of military reserve duty annually. Additionally, all such
residents are subject to being called to active duty at any time under emergency
circumstances. Currently, some of our senior officers and key employees are
obligated to perform annual reserve duty. While we have operated effectively
under these requirements since we began operations, no assessment can be made as
to the full impact of such requirements on our workforce or business if
conditions should change, and no prediction can be made as to the effect on us
of any expansion or reduction of such obligations.

                              ECONOMIC CONDITIONS

     Israel's economy has been subject to numerous destabilizing factors,
including a period of rampant inflation in the early to mid-1980s, low foreign
exchange reserves, fluctuations in world commodity prices, military conflicts
and civil unrest. The Israeli government has, for these and other reasons,
intervened in various sectors of the economy, employing, among other means,
fiscal and monetary policies, import duties, foreign currency restrictions and
controls of wages, prices and foreign currency exchange rates.

     Until May 1998, Israel imposed restrictions on transactions in foreign
currency. These restrictions affected our operations in various ways, and also
affected the right of non-residents of Israel to convert into foreign currency
amounts they received in Israeli currency, such as the proceeds of a judgment
enforced in Israel. Despite these restrictions, foreign investors who purchased
shares with foreign currency were able to repatriate in foreign currency both
dividends, after deduction of withholding tax, and the proceeds from the sale of
the shares. In 1998, the Israeli currency control regulations were liberalized
significantly, as a result of which Israeli residents generally may freely deal
in foreign currency and non-residents of Israel generally may freely purchase
and sell Israeli currency and assets. There are currently no Israeli currency
control restrictions on remittances of dividends on the ordinary shares or the
proceeds from the sale of the shares; however, legislation remains in effect
pursuant to
                                       62
<PAGE>   67

which currency controls can be imposed by administrative action at any time.

                                TRADE AGREEMENTS

     Israel is a member of the United Nations, the International Monetary Fund,
the International Bank for Reconstruction and Development and the International
Finance Corporation. Israel is also a signatory to the General Agreement on
Tariffs and Trade, which provides for reciprocal lowering of trade barriers
among its members. In addition, Israel has been granted preferences under the
Generalized System of Preferences from Australia, Canada and Japan. These
preferences allow Israel to export the products covered by such programs either
duty-free or at reduced tariffs.

     Israel has entered into preferential trade agreements with the European
Union, the United States and the European Free Trade Association. In recent
years, Israel has established commercial and trade relations with a number of
the other nations, including Russia, China and India, with which Israel had not
previously had such relations.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
BackWeb Technologies Ltd.

     We have audited the accompanying consolidated balance sheets of BackWeb
Technologies Ltd. as of December 31, 1997 and 1998, and the related consolidated
statements of operations, redeemable convertible preferred stock and changes in
shareholders' equity (net capital deficiency), and cash flows for each of the
three years in the period ended December 31, 1998. These financial statements
are the responsibility of BackWeb'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 in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
BackWeb Technologies Ltd. at December 31, 1997 and 1998, and the consolidated
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 the United States.

March 31, 1998 and 1999 is unaudited but, in the opinion of management, has been
prepared on the same basis as the annual financial statements and includes all
adjustments (consisting only of normal recurring adjustments) and that BackWeb
considers necessary for a fair presentation of the financial position at such
date and the operating results and cash flows for those periods. Results for the
interim period are not necessarily indicative of the results to be expected for
the entire year.

REVENUE RECOGNITION

     License revenues are comprised of perpetual or multiyear licensee fees
which are primarily derived from contracts with corporate customers and
resellers. License revenue is recognized when a license agreement has been
executed or a definitive purchase order has been received, the product has been
delivered to end customers, no significant BackWeb obligations with regard to
implementation remain, the fee is fixed and determinable, and collectibility is
probable. For electronic delivery, the software is considered to have been
delivered when BackWeb has provided the customer with the access codes that
allow for immediate possession of the software. If the fee due from the customer
is not fixed and determinable, revenue is recognized as payments become due from
the customer. If collectibility is not considered probable, revenue is
recognized when the fee is collected. Revenue on arrangements with customers who
are not the ultimate users (primarily resellers) is not recognized until the
product is delivered to the end user.

     Service revenues are comprised of revenue from support arrangements,
consulting fees and training. BackWeb's policy is to recognize license revenue
when these associated services that are not essential to the functionality of
the product. To date, these services have not been

REVENUE RECOGNITION (CONTINUED)
essential to the functionality of the product. Support arrangements provide
technical support and the right to unspecified upgrades on an
if-and-when-available basis. Revenue from support arrangements is deferred and
recognized on a straight-line basis as services revenue over the life of the
related agreement, which is typically one year. Consulting and training revenue
is deferred and recognized when provided to the customer. Customer advances and
billed amounts due from customers in excess of revenue recognized are recorded
as deferred revenue.

     BackWeb adopted Statement of Position 97-2, "Software Revenue Recognition"
("SOP 97-2"), and Statement of Position 98-4, "Deferral of the Effective Date of
a Provision of SOP 97-2, Software Revenue Recognition" ("SOP 98-4"), as of
January 1, 1998. SOP 97-2 and SOP 98-4 provide guidance for recognizing revenue
on software transactions and supersede Statement of Position 91-1. The adoption
of SOP 97-2 and SOP 98-4 did not have a material impact on BackWeb's financial
results.

     In December 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-9, "Modification of SOP 97-2, Software Revenue
Recognition, With Respect to Certain Transactions" ("SOP 98-9"). SOP 98-9 amends
SOP 98-4 to extend the deferral of the application of certain passages of SOP
97-2 provided by SOP 98-4 through fiscal years beginning on or before March 15,
1999. All other provisions of SOP 98-9 are effective for transactions entered
into in fiscal years beginning after March 15, 1999. BackWeb has not yet
determined the effect of the final adoption of SOP 98-9 on its financial
condition or results of operations.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from these estimates.

RESEARCH AND DEVELOPMENT

     Research and development expenditures are charged to operations as
incurred. Statement of Financial Accounting Standard ("SFAS") No. 86,
"Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise
Marketed," requires capitalization of certain software development costs
subsequent to the establishment of technological feasibility. Based on BackWeb's
product development process, technological feasibility is established upon the
completion of a working model. BackWeb generally does not incur any costs
between the completion of the working model and the point at which the product
is ready for general release. Therefore, through December 31, 1998, BackWeb has
charged all software development costs to research and development expense in
the period incurred.

FOREIGN CURRENCY TRANSACTIONS

     BackWeb has elected to prepare its financial statements in U.S. dollars,
which is also BackWeb's functional currency. Most of our sales are in U.S.
dollars. However, a significant substantial portion of BackWeb's research and
development expenses are denominated in New Israeli Shekels ("NIS"). Since the
U.S. dollar is the primary currency in the economic

environment in which BackWeb conducts its operations the U.S. dollar is the
functional currency of BackWeb Technologies Ltd. and each of its subsidiaries.

     Monetary accounts maintained in currencies other than the dollar
(principally cash and liabilities) are remeasured using the foreign exchange
rate at the balance sheet date in accordance with SFAS No. 52, "Foreign Currency
Translations." Operational accounts and nonmonetary balance sheet accounts are
measured and recorded in current operations at the rate in effect at the date of
the transaction. The foreign currency remeasurement effect for 1998 was a gain
of $163,000. The foreign currency remeasurement effects were insignificant in
1996 and 1997.

ADVERTISING COSTS

     BackWeb accounts for advertising costs as expense in the period in which
the costs are incurred. Advertising expense for the years ended December 31,
1996, 1997 and 1998 were $846,000, $756,000 and $42,000.

CASH EQUIVALENTS

     Cash equivalents consist of money market accounts and bank time deposits.
BackWeb considers all highly liquid investments with an original maturity from
date of purchase of three months or less to be cash equivalents.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost, net of accumulated depreciation.
Property and equipment are depreciated on a straight-line basis over the
estimated useful lives of the assets, generally three to five years.

INTANGIBLE ASSETS

     BackWeb recorded goodwill representing the excess of the aggregate purchase
price over the fair value of the tangible and intangible assets acquired in
connection with the acquisition of Lanacom, Inc., ("Lanacom") (see Note 2).
Goodwill, developed technology and other identified intangibles are amortized on
a straight-line basis over the estimated useful life. The amortization of
developed technology, amounting to $60,000, $160,000 and $40,000 in 1997, 1998
and in the three months ended March 31, 1999 is included in cost of license
revenues. BackWeb regularly performs reviews to determine if the carrying value
of the assets is impaired. The reviews take into consideration the existence of
facts or circumstances, either internal or external, which indicate that the
carrying value of the asset cannot be recovered. No such impairment has been
indicated to date. If such impairment will be indicated, the recoverability
analysis of the long lived assets will consist of calculation of the present
value of the undiscounted expected future cash flows from the respective assets
and comparison of the resulting present value to the carrying

CONCENTRATION OF CREDIT RISK

     Financial instruments, which potentially subject BackWeb to concentrations
of credit risk, consist of cash investments and trade receivables. BackWeb's
cash investments generally consist of money market funds and a certificate of
deposit with qualified financial institutions. The carrying amount of these
financial instruments, as well as debt instruments, are recorded at cost, which
approximates their fair value.

     BackWeb sells its products to customers primarily in the United States.
BackWeb performs ongoing credit evaluations of its customers' financial
condition and generally does not require collateral. BackWeb maintains reserves
to provide for estimated credit losses. Provisions for bad debts in the years
ended December 31, 1997 and 1998 were $485,000 and $677,000. Write-offs of
uncollectible accounts in the years ended December 31, 1997 and 1998 totaled
$10,000 and $591,000. In 1997, revenues from two customers represented 19% and
11% of total revenues. No customer represented more than 10% of total revenues
in 1998.

NET LOSS PER SHARE

     Basic and diluted net loss per share are presented in accordance with SFAS
No. 128, "Earnings per Share" ("SFAS 128"), for all periods presented. Pursuant
to the Securities and Exchange Commission Staff Accounting Bulletin No. 98,
ordinary shares and convertible preferred shares issued or granted for nominal
consideration prior to the anticipated effective date of BackWeb's initial
public offering (the "Offering", see Note 11) must be included in the
calculation of basic and diluted net loss per share as if they had been
outstanding for all periods presented. To date, BackWeb has not had any
issuances or grants for nominal consideration.

     Basic and diluted net loss per share have been computed using the
weighted-average number of ordinary shares outstanding during the period. Basic
and diluted pro forma net loss per share, as presented in the statements of
operations, have been computed as described above and also give effect to the
conversion of all preferred shares excluding, the Series E preferred share

     All preferred stock, outstanding stock options, and warrants have been
excluded from the calculation of the diluted loss per ordinary share because all
such securities are antidilutive for all periods presented. The total number of
ordinary shares related to preferred stock, outstanding options and warrants
excluded from the calculations of diluted net loss per share were 16,069,329,
20,796,354, 25,657,825 and 28,182,944 for the years ended December 31, 1996,
1997, 1998 and the three months ended March 31, 1999. Also excluded from the per
share calculation are the BWC exchangeable shares represented by the one share
of Series E Preferred Stock (see Note 2). Such securities would have been
included in the computation of diluted net income per share using the treasury
stock method.

UNAUDITED PRO FORMA SHAREHOLDERS' EQUITY

     If the Offering is consummated, all of the preferred stock, with the
exception of the Series E preferred stock, will be automatically converted into
ordinary shares upon completion of the Offering (see Note 8). Unaudited pro
forma shareholders' equity at March 31, 1999, as adjusted for the assumed
conversion of such shares, is disclosed on the balance sheet.

STOCK-BASED COMPENSATION

     BackWeb has elected to follow APB 25 and related interpretations in
accounting for its employee stock options. The alternative fair value accounting
provided for under SFAS No. 123, "Accounting for Stock-Based Compensation"
("SFAS 123"), requires use of option valuation models that were not developed
for use in valuing employee stock options. Under APB 25, when the exercise price
of BackWeb's employee stock options equals the market price of the underlying
stock on the date of grant, no compensation expense is recognized. See the pro
forma disclosures of the application of SFAS 123 in Note 8.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     Effective January 1, 1998, BackWeb adopted SFAS No. 130, "Reporting
Comprehensive Income" ("SFAS 130"). SFAS 130 establishes standards for reporting
and display of comprehensive income and its components in a full set of general
purpose financial statements. Adoption of SFAS 130 had no impact on BackWeb's
financial position, results of operations and disclosures, as BackWeb had no
items of other comprehensive income in any period presented.

     Effective January 1, 1998, the Company adopted SFAS No. 131, "Disclosures
About Segments of an Enterprise and Related Information" ("SFAS 131"). SFAS 131
superseded SFAS No. 14, "Financial Reporting for Segments of a Business
Enterprise." SFAS 131 establishes standards for the way that public business
enterprises report information about operating segments in interim financial
reports. SFAS 131 also establishes standards for related disclosures about
products and services, geographic areas, and major customers. The adoption of
SFAS 131 did not effect results of operations or financial position, but did
affect the disclosure of geographic information for assets (see Note 10).

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS 133"). BackWeb is required to adopt
SFAS 133 for the year ending December 31, 2000. SFAS 133 establishes methods of
accounting for derivative financial instruments and hedging activities. Because
BackWeb currently holds no derivative financial instruments as defined by SFAS
133 and does not currently engage in hedging activities, adoption of SFAS 133 is
not expected to have a material effect on BackWeb's financial condition or
results of operations.

     In March 1998, the American Institute of Certified Public Accountants
issued SOP 98-1, "Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use" ("SOP 98-1"). SOP 98-1 requires that entities
capitalize certain costs related to internal use software once certain criteria
have been met. BackWeb is required to implement SOP 98-1 for the year ending
December 31, 1999. Adoption of SOP 98-1 is not expected to have a material
impact on BackWeb's financial condition or results of operations.

2. ACQUISITION OF LANACOM, INC.

     In August 1997, BackWeb acquired all of the outstanding shares of Lanacom,
a Canadian corporation, a developer of technology software products in a
stock-for-stock transaction. The transaction was carried out through a wholly
owned subsidiary of BackWeb Technologies Ltd., BackWeb Canada, Inc. ("BWC"), and
was accounted for under the purchase method of accounting.

2. ACQUISITION OF LANACOM, INC. (CONTINUED)
     Under the terms of the agreement, BackWeb issued 8,532,909 shares of BWC
and granted options to purchase 341,667 BackWeb ordinary shares, to Lanacom's
stock and option holders at the date of the acquisition. 2,867,373 shares of BWC
exchangeable common shares were placed in escrow. The escrow shares were to be
distributed to the Lanacom shareholders during 1998, and were for the
satisfaction of (i) any shortfall in Lanacom's recorded net liabilities at the
closing or (ii) any losses to BackWeb resulting from any losses incurred by
BackWeb by reason of the breach by Lanacom of any representations, warranties,
covenants or agreements in the acquisition agreement. As of the date of the
acquisition, management believed that all escrow shares were to be distributed
to Lanacom's shareholders. On March 25, 1999, BackWeb entered into a settlement
agreement and mutual release with a former shareholder of Lanacom pursuant to
which 746,404 shares of BWC exchangeable common stock which had been previously
held in escrow and which were further subject to certain employment continuation
conditions, under the former shareholder employment contract, were released to
BackWeb. The release of these shares is reflected in the financial statements at
December 31, 1998.

     Each exchangeable BWC share issued in connection with the acquisition is
exchangeable, at any time and at the election of the holder thereof, into 0.33
ordinary shares of BackWeb reflecting the one-for-three reverse ordinary stock
split described in Note 11 (subject to further adjustments for stock splits,
stock dividends, reclassifications, and the like). In connection with the
acquisition, BackWeb issued one share of Series E preferred stock which entitled
each holder of a BWC exchangeable share to voting rights equal to 0.33 ordinary
shares of BackWeb, reflecting the one-for-three reverse ordinary stock split.

     The purchase price of $3,904,000 was determined based on the value of the
shares originally issued and options granted. The purchase price was allocated
based upon the estimated fair value of the net assets acquired as follows (in
thousands):

     The acquired developed technology is comprised of three related software
products which as of the acquisition date, had achieved technological
feasibility. The valuation was based on the stand alone technology of Lanacom,
not considering BackWeb's plans of integration. To determine the value of the
acquired developed technology, the expected future cash flows of the existing
developed technology were based on forecasts of future results that management
believed were likely to occur, at the time of the acquisition. However, no
assurance can be given that deviations from these projections will not occur.
The future cash flows were discounted taking into account the expected income
stream, size of existing markets, growth rates of existing and future markets,
as well as the evaluation of anticipated product life cycles, and associated
risks. Revenues and related expenses for the developed technology were estimated
from the date of the acquisition and extended through the year 2000.

PRO FORMA FINANCIAL INFORMATION

     The operations of Lanacom are included in BackWeb's consolidated operating

     In 1995, BackWeb signed an agreement with its early investors (the "Early
Investors"), according to which the Early Investors provided BackWeb with loan
financing in the amount of

5. RELATED PARTIES (CONTINUED)

SHAREHOLDERS' LOAN (CONTINUED)
$500,000. The loan is denominated in NIS and linked to the Israeli consumer
price index. The loan is payable at a rate of 2.5% of cumulative consolidated
revenues in excess of $5,000,000. In addition, effective September 30, 1996,
$748,000 of accounts payable to the Early Investors were converted into a
shareholders' loan on the same terms as the $500,000 loan. As of December 31,
1998, no repayment has been made. As of December 31, 1998, the loan balance,
reflecting currency conversion adjustments, is $1,155,000. As of March 31, 1999,
the loan balance was $927,000 reflecting currency conversion adjustments and
repayment.

SERVICES FROM AFFILIATES

     The Early Investors provide BackWeb with professional services relating
primarily to management and administrative services, in return for reimbursement
of specifically identified expenses and salaries. Amounts incurred for these
services were approximately $540,000, $516,000, $220,000 and $24,000 during the
years ended December 31, 1996, 1997, 1998 and the three months ended March 31,
1999.

     BackWeb reimburses BRM Technologies Ltd. ("BRM"), a related party, for
technology and administrative services on the basis of specific cost plus markup
and specifically identified expenses at cost. Amounts incurred for these
services were approximately $1.6 million, $1.2 million, $873,000 and $67,000
during the years ended December 31, 1996, 1997, 1998 and the three months ended
March 31, 1999.

     BackWeb believes that the amounts charged in connection with the services
from founders approximate the cost that would have been incurred if BackWeb
would have incurred these costs internally.

STOCK OPTIONS

     Pursuant to the Founding Agreement, BackWeb granted to its Early Investors
the right to grant stock options for up to 792,167 ordinary shares any person or
entity. Through December 31, 1998, options for 722,084 ordinary shares have been
granted and 70,083 shares remained available and are reflected in the option
activity summary in Note 8. This pool of options has been used by the Early
Investors in granting options to employees and consultants of BRM and related
companies.

     Deferred compensation expense related to the Early Investors' options
amounting to $290,000 is included in amortization of goodwill, other intangibles
and deferred stock compensation for the three months ended March 31, 1999. No
compensation expense was recorded in prior periods as amounts ascribed to these
options were immaterial.

     Rent expense approximated $165,000, $458,000, and $695,000 for the years
ended December 31, 1996, 1997, and 1998.

BANK LINE OF CREDIT

     In December 1998, BackWeb entered into a line of credit agreement with a
bank which provides for formula and nonformula revolving credit loans
aggregating up to $6,500,000. The line of credit is secured by substantially all
of BackWeb's assets. Borrowings under the line of credit bear interest at the
bank's prime rate plus 2%-4%. The borrowing under the line of credit at December
31, 1998 and March 31, 1999 in the amount of $2,000,000 bears interest at prime
plus 4%.

     The amount available under the formula loans is limited to the lower of
$3,000,000 or an amount equal to 85% of eligible accounts receivable. The amount
available under the nonformula loans and term loans are $2,000,000 and
$1,500,000, respectively. As of December 31, 1998, BackWeb had $1,220,000 in
unused availability under the formula and nonformula line of credit and utilized
$2,000,000 of the amount available under the line of credit. The loan is due in
December 1999.

     In 1997, BackWeb had a credit agreement with a different financial
institution. BackWeb repaid the outstanding balance under this credit agreement
in 1998.

ROYALTY COMMITMENTS

     In 1997, BackWeb entered into an in-license agreement which include future
royalty commitments at the rate of generally 1% of product revenues which
incorporate the licensed technology into products sold by BackWeb. As of
December 31, 1998, such royalty commitments have not been met.

7. ACCRUED SEVERANCE PAY, NET

     BackWeb's liability for severance pay is calculated pursuant to Israeli
severance pay law based on the most recent salary of the employees multiplied by
the number of years of employment as of the balance sheet date. BackWeb records
as expense the net increase in its funded or unfunded severance liability.
Employees are entitled to one month salary for each year of employment, or a
portion thereof. The Company's liability is fully provided by monthly deposits
with severance pay funds, insurance policies and by an accrual. Deposits with
severance pay funds and insurance policies are not under the control of BackWeb.

the obligation pursuant to Israeli severance pay law or labor agreements. The
value of the deposited funds are based on the cash surrendered value of these
policies, and include the accumulated investment income, which has been
immaterial to date.

underwritten public offering of ordinary shares in which BackWeb receives at
least $15,000,000 of net proceeds and the offering price per share is at least
$6.90 (subject to adjustment for share splits, share dividends, and like
events).

     Series A convertible preferred shareholders are entitled to receive
dividends as and when declared for holders of ordinary shares calculated on the
basis of the number of ordinary shares into which Series A convertible preferred
stock could then be converted. Series B, C, and D redeemable convertible
preferred shareholders are entitled to dividends in preference to other shares
at an annual rate equal to 7% of the applicable issuance price when declared by
the board of directors out of legally available funds. No dividends have been
declared as of December 31, 1998.

     The Series A convertible preferred shareholders and the Series B, C, and D
redeemable convertible preferred shareholders are entitled to receive, upon
liquidation and in certain circumstances as upon a merger, acquisition or
similar event, an amount per share equal to the equivalent in Israeli currency
(subject to stock splits, stock dividends, reclassifications, and the like) at
$0.0795, $0.757, $1.15, and $1.15, plus all declared but unpaid dividends. Any
remaining assets shall be distributed on a pro rata basis among the holders of
all preferred and ordinary shares.

     The Series A convertible preferred shareholders and the Series B, C, and D
redeemable convertible preferred shareholders have voting rights based on the
number of ordinary shares into which the preferred stock is convertible into.

     With the consent of a majority of the Series B, C-1, and D redeemable
convertible preferred stock, in each case, voting separately as a single class,
BackWeb, at the discretion of the board of directors, may redeem, in whole or in
part, any of the outstanding Series B, C, or D redeemable convertible preferred
stock at the price paid for each share plus all declared but unpaid dividends.
In addition, upon the written request at any time after the 10th anniversary of
the issuance of the Series D redeemable convertible preferred share, of the
holders of a majority of the Series B, C-1, and D redeemable convertible
preferred stock, voting together as a single class, BackWeb shall redeem all the
Series B, C, and D redeemable convertible preferred stock outstanding at the
applicable issuance price, together with all declared but unpaid dividends.

     Series E preferred stock was issued to a trustee in connection with the
Lanacom acquisition (see Note 2) and represents the voting and exchange rights
of the BWC exchangeable common shares. The registered holder of the Series E
preferred stock is entitled to have a number of votes equal to the number of
outstanding exchangeable shares of BWC. The holder of the Series E preferred
stock shall not be entitled to receive any dividend declared and paid by
BackWeb. However, if such dividend is declared by BackWeb, an equivalent
dividend will be declared simultaneously by BWC on the exchangeable shares.
Series E preferred stock shall be canceled when there will be no outstanding
exchangeable shares of BWC.

     On March 24, 1999, BackWeb issued 8,647,815 shares of Series D redeemable

STOCK WARRANTS

     In December 1996 and March 1997, in connection with the Series C financing,
BackWeb issued warrants to purchase 1,810,432 Series C-2 redeemable convertible
preferred shares at an exercise price of $1.15 per share. In December 1998,
warrants to purchase 938,536 shares were exercised while the remainder of

     In August 1997, in connection with a bank line of credit, BackWeb issued a

statement purposes.

     In December 1998, in connection with a bank loan, BackWeb issued a warrant
for the purchase of 385,000 shares of Series C-2 redeemable convertible
preferred shares at $1.15 per share. The warrant is exercisable through the
earlier of a merger or consolidation of BackWeb, or December 2003. The warrant
fair value of $224,000 is amortized over the term of the bank line of credit.

STOCK OPTION PLANS

     Under the 1996 Israeli Stock Option Plan (the "1996 Israeli Plan"), BackWeb
is authorized to grant options to purchase ordinary shares to its Israeli
employees and other eligible participants. Options granted under the 1996
Israeli Plan expire seven years from the date of grant and terminate upon
termination of the optionee's employment or other relationship with BackWeb. The
options vest ratably over a four-year period.

     Under the 1996 U.S. Stock Option Plan (the "1996 U.S. Plan"), BackWeb is
authorized to grant incentive stock options to employees and nonstatutory stock
options to employees, officers, directors and consultants at BackWeb or any

generally vest over a four year period. BackWeb is no longer granting options
under the 96 U.S. Plan. In the event of merger, sale or dissolution of the
Company, all options will terminate immediately, except to the extent options
are assumed by the successor Company.

     Under the 1998 U.S. Option Plan (the "1998 U.S. Plan"), BackWeb is
authorized to grant incentive stock options to employees and nonstatutory stock
options and share purchase rights to employees, directors and consultants. The
exercise price of incentive stock options must not be less than the fair market
value of its ordinary share at the date of grant. Options granted under the 1998
U.S. Option Plan generally vest over four years. In the event of an acquisition
of BackWeb, if the options are not assumed by the successor corporation, the
options will accelerate and become fully vested.

     As of December 31, 1998, an aggregate of 6,666,667 shares have been
reserved under the 1996 Israeli Plan, the 1996 U.S. Plan and the 1998 U.S. Plan,
including those options already exercised.

     BackWeb's 1999 Employee Stock Purchase Plan was adopted by the board of
directors on March 25, 1999 to be effective following the Offering. BackWeb has
reserved a total of 600,000 shares for issuance under the plan. The number of
shares reserved under the plan is subject to an annual increase on each
anniversary beginning July 1, 2000 equal to lesser of 833,333 shares, 2% of the
then outstanding shares or an amount determined by the Board. Eligible employees
may purchase ordinary shares at 85% of the lesser of the fair market value of
BackWeb's ordinary shares on the first day of the applicable offering period or
the last day of the applicable purchase period.

     Also on March 25, 1999, the board of directors approved an increase to the
number of shares reserved under the 1998 U.S. Plan by 3,600,000. The number of
shares authorized and reserved under the plan will be subject to an annual
increase on each anniversary beginning July 1, 2000 equal to the lesser of
1,400,000 shares, 3% of the outstanding shares on such date or an amount
determined by the Board.

STOCK OPTION PLANS (CONTINUED)
     As of March 31, 1999, there were 1,692,954 ordinary shares options
exercisable at a weighted average exercise price of $0.9.

     During the year ended December 31, 1998 and the three months ended March
31, 1999, in connection with the grant of certain share options, BackWeb
recorded deferred stock compensation of $1,859,000 and $2,608,000 respectively
representing the difference between the exercise price and the deemed fair value
of BackWeb's ordinary share on the date such stock options were granted. Such
amount is being amortized based on an accelerated method over the vesting period
of the options, generally four years. In 1998 and the three months ended March
31, 1999, BackWeb recorded amortization of deferred stock compensation expense
of approximately $221,000 and $807,000 respectively. At March 31, 1999, BackWeb
had a total of $3,439,000 remaining to be amortized.

RESTRICTED SHARES ISSUED FOR PROMISSORY NOTES

     On March 25, 1999, several key employees and one director exercised options
for 1,141,333 ordinary shares for promissory notes in the aggregate amount of
$3,538,000. The notes are full recourse and are secured by the shares, bear
interest at a rate of 6% per annum and are payable over the remaining options
vesting period. The shares are restricted and are subject to a right of
repurchase in favor of BackWeb in accordance with the original options' vesting
schedule which is generally four years.

ACCOUNTING FOR STOCK-BASED COMPENSATION

     Pro forma information regarding net loss is required by SFAS 123, which
also requires that the information be determined as if BackWeb has accounted for
its employee stock options under the fair value method of that Statement. The
fair value for these awards was estimated at the date of grant using the minimum
value options pricing model. The minimum value options pricing valuation model
was developed for use in estimating the fair value of options that have no
vesting restrictions and are fully transferable. Option valuation models require
the input of highly subjective assumptions. Because BackWeb's stock-based awards
have characteristics significantly different from those of traded options and
because changes in the subjective input assumptions can materially affect the
fair value estimate, in management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of its
stock-based awards. The fair value of these options was estimated at the date of
grant using the minimum value method option pricing model with the following
weighted-average assumptions for 1996, 1997, and 1998: risk-free interest rates
of approximately 6%, no dividend yield; and a weighted-average expected life of
the option of approximately 3.46, 3.32, and 3.34 years.

     Pretax loss from foreign operations (non-Israeli) was $719,000 in 1996,
$2,648,000 in 1997 and $3,621,000 in 1998.

ISRAELI INCOME TAXES

     BackWeb's investment program has been granted the status of "Approved
Enterprise" by the Israeli government under the law for the Encouragement of
Capital Investments, 1959 (the "Law"). Israeli income derived from the "Approved
Enterprise" entitles BackWeb to tax exemption for a period of two years
commencing the first year that it will earn taxable income, and to a reduced tax
rate of 10%-25% for an additional 5 to 8 year period (depending on the rate of
foreign investment in BackWeb). The tax benefit period is limited to the
earliest of 12 years from completion of the investment under the plan or
December 31, 2009. Thereafter, BackWeb will be subject to the regular corporate
tax rate of 36% on its Israeli income. Income from sources other than the
"Approved Enterprise" will be subject to tax at the regular rate of 36%.

     BackWeb currently has no plans to distribute such tax-exempt income as
dividend and intends to retain future earnings to finance the development of the
business. If the retained tax-exempt income is distributed in a manner other
than in the complete liquidation of BackWeb, it would be taxed at the corporate
tax rate applicable to such profits (currently 25%). As of December 31, 1998,
BackWeb is in the process of completing the investments required under the
program. Should BackWeb fail to meet conditions stipulated by the law and by the
Approval certification, including making specified investments in fixed assets,
maintaining the development and production nature of its facilities, and
financing of at least 30% of the investment program through equity, it could be
subject to corporate tax in Israel at the corporate rate of 36% and could be
required to refund tax benefits already received at that time (inclusive of
interest and penalties).

     As of December 31, 1998, BackWeb had approximately $30,000,000 of Israeli
net operating loss carryforwards. The Israeli loss carryforwards have no
expiration date. The Company expects that during the period these tax losses are
utilized, its income would be substantially tax exempt.

ISRAELI INCOME TAXES (CONTINUED)
Accordingly, there will be no tax benefit available from such losses and no
deferred income taxes have been included in these financial statements.

U.S. INCOME TAXES

     At December 31, 1998, BackWeb had a U.S. federal net operating loss
carryforward for income tax purposes of approximately $1,000,000. The net
operating loss expires in various amounts between the years 2011 and 2018.

     Utilization of U.S. net operating losses may be subject to substantial
annual limitation due to the "change in ownership" provisions of the Internal
Revenue Code of 1986 and similar state provisions. The annual limitation may
result in the expiration of net operating losses before utilization.

DEFERRED INCOME TAXES

     Deferred tax assets and liabilities reflect the net tax effects of net
operating loss and of temporary differences between the carrying amounts of
assets and liabilities for financial reporting and the amounts used for income
tax purposes. Significant components of BackWeb's deferred tax assets and
liabilities for federal and state income taxes are as follows:

11. PROPOSED PUBLIC OFFERING AND RELATED MATTERS

     The board of directors has authorized BackWeb to file a registration
statement with the U.S. Securities and Exchange Commission for an initial public
offering of its ordinary shares.

     On March 25, 1999, the board of directors approved a one-for-three reverse
ordinary stock split. The reverse stock split will be effected prior to the
effective date of the Offering. All ordinary share numbers and preferred stock
conversion ratios have been retroactively adjusted to reflect the reverse stock
split.

     Also on March 25, 1999, the board of directors approved an increase in the
authorized share capital of BackWeb to 150,000,000 ordinary shares and
50,000,000 shares of undesignated preferred stock.

                                  UNDERWRITING

     BackWeb and the underwriters named below have entered into an underwriting
agreement with respect to the shares being offered. Subject to certain
conditions, each underwriter has severally agreed to purchase the number of
shares indicated in the following table. Goldman, Sachs & Co., BancBoston
Robertson Stephens Inc., Lehman Brothers Inc. and Wit Capital Corporation are
the representatives of the underwriters.

</TABLE>

     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 825,000
shares from BackWeb 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 BackWeb. Such amounts are
shown assuming both no exercise and full exercise of the underwriters' option to
purchase additional shares.

</TABLE>

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

     Wit Capital, a member of the National Association of Securities Dealers,
Inc. will participate in the offering as one of the underwriters. The National
Association of
Securities Dealers, Inc. approved the membership of Wit Capital on September 4,
1997. Except for its participation as a manager in this offering, Wit Capital
has no relationship with BackWeb or any of its founders or significant
shareholders.

     We have agreed with the underwriters not to dispose of or hedge any of our
ordinary shares or securities convertible into or exchangeable for ordinary
shares during the period from the date of this prospectus continuing through the
date 180 days after the date of this prospectus, except for certain gift to
immediate family or with the prior written consent of the representatives. This
agreement does not apply to any existing employee benefit plans. See "Shares
Eligible for Future Sale" for a discussion of certain transfer restrictions.

     In addition, our officers and directors and substantially all holders of
shares of capital stock of BackWeb have agreed that, subject to certain limited
exceptions, they will not offer to sell, sell, contract to sell, pledge, grant
any option to purchase, make any short sale or otherwise dispose of any ordinary
shares owned of record or beneficially prior to the offering or any securities
convertible into or exchangeable for such ordinary shares, for a period of 180
days following the date of the final prospectus for this offering without the
prior written consent of the representatives (other than certain transfers to
immediate family).

                                       U-1
<PAGE>   96

     At our request, the underwriters have reserved up to 349,000 ordinary
shares for sale, at the initial public offering price, to employees and other
friends of BackWeb through a directed share program. BackWeb has requested that
the underwriters reserve an additional 200,000 ordinary shares at the initial
public offering price to be offered to U S WEST Innovations, Inc., an affiliate
of U S WEST Communications, Inc., one of BackWeb's customers. The number of
ordinary shares available for sale to the general public in the public offering
will be reduced to the extent such persons purchase such reserved shares.

     Prior to the offering, there has been no public market for the shares. The
initial public offering price has been negotiated among BackWeb and the
representatives. Among the factors to be considered in determining the initial
public offering price of the shares, in addition to prevailing market
conditions, will be BackWeb's historical performance, estimates of our business
potential and earnings prospects, an assessment of our management and the
consideration of the above factors in relation to market valuation of companies
in related businesses.

     We have applied for quotation of the ordinary shares on the Nasdaq National
Market under the symbol "BWEB."

     In connection with the offering, the underwriters may purchase and sell
ordinary shares 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 the 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 ordinary shares
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 ordinary shares. As a result, the price of the
ordinary shares 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.

     The underwriters do not expect sales to discretionary accounts to exceed
five percent of the number of shares offered.

     We estimate that our share of the total expenses of the offering, excluding
underwriting discounts and commissions, will be approximately $1.7 million.

     We have agreed to indemnify the several underwriters against liabilities
under the Securities Act of 1933 or contribute to payments which the
underwriters may be required to make in that respect.

     Certain investment partnerships of which affiliates of The Goldman Sachs
Group, L.P., an affiliate of Goldman Sachs (lead manager of this offering), are
general partner, managing general partner or investment manager, hold 9,818,029
preferred shares of BackWeb which upon the closing of this offering convert into
3,272,676 ordinary shares. In January 1998, BancAmerica Robertson Stephens Inc.,
an affiliate of BancBoston Robertson Stephens, one of the underwriters in this
offering, participated as the placement agent for the Series D Preferred Shares.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Israeli law permits a company to insure an office holder in respect of
liabilities incurred by him as a result of the breach of his duty of care to the
company or to another person, or as a result of the breach of his fiduciary duty
to the company, to the extent that he acted in good faith and had reasonable
cause to believe that the act would not prejudice the company. A company can
also insure an office holder for monetary liabilities as a result of an act or
omission that he committed in connection with his serving as an office holder.
Furthermore, a company can indemnify an office holder for monetary liability in
connection with his activities as an office holder.

     The Articles of Association of BackWeb allow BackWeb to insure and
indemnify office holders to the fullest extent permitted by law. BackWeb has
acquired directors' and officers' liability insurance covering the officers and
directors of BackWeb and its subsidiaries for certain claims.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

     (a) Since January 1, 1996, the Registrant has issued and sold (without
         payment of any selling commission to any person) the following
         unregistered securities:

     (1) Prior to the completion of this offering, the Registrant intends to
         effect a three-for-one reverse stock split of its outstanding ordinary
         shares in which every outstanding ordinary share will be split into
         three ordinary shares.

     (2) In July 1996, the Registrant issued and sold its Series B Preferred
         Shares convertible into an aggregate of 1,412,547 ordinary shares to a
         total of two investors for an aggregate purchase price of

     (3) From December 1996 to March 1997, the Registrant issued and sold its
         Series C Preferred Shares convertible into an aggregate of 4,197,101

         price of $1,079,316.

     (5) In August 1997, in connection with the Registrant's acquisition of
         Lanacom Inc., a Canadian company, the Registrant issued its
         exchangeable shares convertible into an aggregate of 2,844,303 ordinary
         shares.

     (6) From December 1997 to March 1999, the Registrant issued and sold its
         Series D Preferred Shares convertible into an aggregate of 8,679,707

         the transactions set forth in Item 15(a).

registration under Section 2(3) of the Securities Act on the basis that such
transaction did not involve a "sale" of securities. The issuances described in
Items 15(a)(2), 15(a)(3), 15(a)(4), 15(a)(5) and 15(a)(6) were deemed exempt
from registration under the Securities Act in reliance upon Section 4(2) thereof
as transactions by an issuer not involving any public offering. The issuances
described in Item 15(a)(7) were deemed exempt from registration under the
Securities Act in reliance upon Rule 701 promulgated thereunder in that they
were offered or sold either pursuant to a written contract relating to
compensation, as provided by Rule 701. In addition, such issuances were deemed
to be exempt from registration under Section 4(2) of the Securities Act as
transactions by an issuer not involving any public offering. The recipients of
securities in each such transaction represented their intentions to acquire the
securities for investment only and not with a view to or for sale in connection
with any distribution thereof and appropriate legends where affixed to the
securities issued in such transactions. All recipients had adequate access,
through their relationships with the Registrant, to information about the
Registrant.

forth therein is not applicable or is shown in the consolidated financial
statements and notes thereto.

ITEM 17. UNDERTAKINGS

     The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, 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

                                      II-3
<PAGE>   101

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.

     The undersigned registrant hereby undertakes that:

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

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

                                   SIGNATURES


     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 F-1 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 the City of San Jose, California, on June 3,
1999.

        marketable title to all personal property owned by them, in each case
        free and clear of all liens, encumbrances and defects except such as are
        described in the Prospectus or such as do not materially affect the
        value of such property and do not interfere with the use made and
        proposed to be made of such property by the Company and the
        Subsidiaries; and any real property and buildings held under lease by
        the Company and the Subsidiaries are held by them under valid,

        respect to any differences.

        omit to state any material fact necessary in order to make the
        statements therein, in the light of the circumstances under which they
        were made when such Prospectus is delivered, not misleading, or, if for

               trust, loan agreement or other agreement or instrument known to
               such counsel to which the U.S. Subsidiary is a party or by which
               the U.S. Subsidiary is bound or to which any of the property or
               assets of the U.S. Subsidiary is subject and which is filed as an
               exhibit to the Registration Statement, nor will such action

               consummation of the transactions contemplated by this Agreement
               and to official notice of issuance;

                      (ix)   No Governmental Authorization of the United States
               or the States of California or Delaware is required for the

               except the registration under the Act of the Shares or filings
               and other actions required pursuant to the Securities Exchange
               Act of 1934, as amended, and the rules and regulations thereof,

               and such consents, approvals, authorizations, registrations or
               qualifications as may be required under state securities or Blue
               Sky laws in connection with the purchase and distribution of the

                      (x)    The statements set forth in the Prospectus under
               the caption "United States Federal Income Tax Considerations",
               insofar as they purport to describe the provisions of United
               States Federal income tax laws referred to therein, are accurate
               summaries and descriptions of such terms and provisions in all
               material respects, subject to the limitations set forth therein;

                      (xi)   The Company is not an "investment company", as such
               term is defined in the Investment Company Act; and

                      (xii)  The Registration Statement and the Prospectus and
               any further amendments and supplements thereto made by the
               Company prior to such Time of Delivery (other than the financial
               statements and notes thereto and related schedules and the other
               financial and accounting data included therein or omitted
               therefrom, as to which such counsel need express no opinion) as
               of their respective effective and issue dates complied as to form
               in all material respects with the requirements of the Act and the
               rules and regulations thereunder.

                             Although they have not independently verified or
               confirmed and do not assume any responsibility for the accuracy,
               completeness or fairness of the statements contained in the
               Registration Statement or the Prospectus, except to the limited
               extent set forth to in the opinion in subsection (xi) of this
               Section 7(c), nothing has come to their attention that has caused
               them to believe that, as of its effective date or such Time of
               Delivery, the Registration Statement or any further amendment
               thereto made by the Company prior to such Time of Delivery (other
               than the financial statements and notes thereto and related
               schedules and the other financial and accounting data included
               therein or omitted therefrom, as to which such counsel need
               express no opinion) contained an untrue statement of a material
               fact or omitted to state a material fact required


<PAGE>   15

               to be stated therein or necessary to make the statements therein
               not misleading, or that, as of its date or such Time of Delivery,
               the Prospectus or any further amendment or supplement thereto
               made by the Company prior to such Time of Delivery (other than
               the financial statements and notes thereto and related schedules
               and the other financial and accounting data included therein or
               omitted therefrom, as to which such counsel need express no
               opinion) contained an untrue statement of a material fact or
               omitted to state a material fact required to be stated therein or
               necessary to make the statements therein not misleading; and they
               do not know of any amendment to the Registration Statement
               required to be filed or of any contracts or other documents of a
               character required to be filed as an exhibit to the Registration
               Statement or required to be described in the Registration
               Statement or the Prospectus which are not filed or described as
               required.

               In rendering such opinion, such counsel may state that they
        express no opinion as to the laws of any jurisdiction other than the
        States of California and Delaware and the federal laws of the United
        States.

               by the Company to or for the account of the several Underwriters

               adversely to the Company or any of the Subsidiaries, would
               individually or in the aggregate have a material adverse effect
               on the current or future consolidated financial position,
               shareholders' equity or results of operations of the Company and
               the Subsidiaries; and such counsel is not aware of any such

               of the Shares by the Company or the consummation by the Company
               of the transactions contemplated by this Agreement, except such
               as have been duly obtained and are in full force and effect;

                      (ix)   The statements in the Prospectus under "Description
               of Share Capital", insofar as they purport to constitute a
               summary of the terms of the Ordinary Shares and under the
               captions "Risk Factors -- We are incorporated in Israel and have
               important facilities and resources located in Israel", "-- We
               rely upon tax benefits and other funding from the State of
               Israel", "-- Israeli courts might not enforce judgments rendered
               outside of Israel", and "Israeli Taxation and Investment
               Programs", to the extent such statements relate to matters of law
               or regulation or to the provisions of documents therein
               described, are accurate summaries of such matters in all material
               respects;

                      (x)    No stamp or other issuance or transfer taxes or
               duties and no capital gains, income, withholding or other taxes
               are payable by or on behalf of the Underwriters to the State of
               Israel or to any political subdivision or taxing authority
               thereof or therein in connection with the sale and delivery by
               the Company of the Shares to or for the respective accounts of
               the Underwriters in the manner contemplated herein;

                      (xi)   Insofar as matters of Israeli law are concerned,
               the Registration Statement and the filing of the Registration
               Statement with the Commission have been duly authorized by and on
               behalf of the Company; and the Registration Statement has been
               duly executed pursuant to such authorization by and on behalf of
               the Company;

                      (xii)  The Company's agreement to the choice of law
               provisions set forth in Section 17 hereof will be recognized by
               the courts of the State of Israel; the Company can sue and be
               sued in its own name under the laws of the State of Israel; the
               irrevocable submission of the Company to the exclusive
               jurisdiction of a New York Court, the waiver by the Company of
               any objection to the venue of a proceeding of a New York Court
               and the agreement of the Company that this Agreement shall be
               governed by and construed in accordance with the laws of the
               State of New York are legal, valid and binding; and service of
               process effected in the manner set forth in Section 14 hereof
               will be effective, insofar as the law of the State of Israel is
               concerned, to confer valid personal jurisdiction over the
               Company. Subject to certain time limitations, an Israeli court
               may declare a judgment obtained in a New York Court arising out
               of or in relation to the obligations of the Company under this
               Agreement enforceable against the Company if it finds that (a)
               the judgment was rendered by a court which was, according to the
               laws of the state of the court, competent to render the judgment;
               (b) the judgment is no longer appealable; (c) the obligation
               imposed by the judgment is enforceable according to the rules
               relating to the enforceability of judgments in Israel and the
               substance of the judgment is not contrary to public


<PAGE>   18

               policy; and (d) the judgment is executory in the state in which
               it was given. Even if the above conditions are satisfied, an
               Israeli court will not enforce a foreign judgment such as the
               above if it was given in a state whose laws do not provide for
               the enforcement of judgments of Israeli courts (subject to
               exceptional cases) or if its enforcement is likely to prejudice
               the sovereignty or security of the State of Israel. An Israeli
               court also will not declare a foreign judgment such as the above
               enforceable if (i) the judgment was obtained by fraud, (ii) there
               was no due process, (iii) the judgment was rendered by a court
               not competent to render it according to the laws of private
               international law in Israel, (iv) the judgment is at variance
               with another judgment that was given in the same manner between
               the same parties and which is still valid, or (v) at the time the
               action was brought in the foreign court a suit in the same manner
               and between the same parties was pending before a court or
               tribunal in Israel;

                      (xiii) All dividends and other distributions declared and
               payable on the Shares may under the current laws and regulations
               of the State of Israel be paid in New Israeli Shekels that may be
               converted into foreign currency that may be freely transferred
               out of the State of Israel, and, except as set forth in the
               Prospectus, all such dividends and other distributions will not
               be subject to withholding or other taxes under the laws and
               regulations of the State of Israel and are otherwise free and
               clear of any other tax, withholding or deduction in the State of
               Israel and without the necessity of obtaining any Governmental
               Authorization in the State of Israel;

                      (xiv)  The Company is not in violation of its charter
               documents or, to such counsel's knowledge, in default in the
               performance or observance of any material obligation, agreement,
               covenant or condition contained in any indenture, mortgage, deed
               of trust, loan agreement, lease or other agreement or instrument
               to which it is a party or by which it or any of its properties
               may be bound;

                      (xv)   To the best of such counsel's knowledge, (a) the
               Company has all licenses and concessions of and from all
               Governmental Agencies that are necessary to own or lease its
               properties and conduct its businesses as described in the
               Prospectus; and (b) the Company has all franchises, permits,
               authorizations, approvals and orders and other licenses and
               concessions of and from all Governmental Agencies that are
               necessary to own or lease its other properties and conduct its
               businesses as described in the Prospectus except for such
               licenses, franchises, permits, authorizations, approvals and
               orders the failure to obtain which will not have a material
               adverse effect on the financial condition or results of
               operations of the Company and the Subsidiaries; and

                      (xvi)  Although they do not assume any responsibility for
               the accuracy, completeness or fairness of the statements
               contained in the Registration Statement or the Prospectus, except
               for those referred to in the opinion in subsection (x) of this
               Section 7(d), they have no reason to believe that, as of its
               effective date, the Registration Statement or any further
               amendment thereto made by the Company prior to such Time of
               Delivery (other than the financial


<PAGE>   19

               statements and related schedules therein, as to which such
               counsel need express no opinion) contained an untrue statement of
               a material fact or omitted to state a material fact required to
               be stated therein or necessary to make the statements therein not
               misleading or that, as of its date, the Prospectus or any further
               amendment or supplement thereto made by the Company prior to such
               Time of Delivery (other than the financial statements and related
               schedules therein, as to which such counsel need express no
               opinion) contained an untrue statement of a material fact or
               omitted to state a material fact necessary to make the statements
               therein, in the light of the circumstances under which they were
               made, not misleading or that, as of such Time of Delivery, either
               the Registration Statement or the Prospectus or any further
               amendment or supplement thereto made by the Company prior to such
               Time of Delivery (other than the financial statements and related
               schedules therein, as to which such counsel need express no
               opinion) contains an untrue statement of a material fact or omits
               to state a material fact necessary to make the statements
               therein, in the light of the circumstances under which they were
               made, not misleading.

               In giving such opinion, such counsel may state that with respect
        to all matters of United States law they have relied upon the opinions
        of United States counsel for the Company delivered pursuant to paragraph
        (c) of this Section 7.

               (f)    On the date of the Prospectus of a time prior to the
        execution of this Agreement, at 9:30 a.m., New York City time, on the
        effective date of any post-effective amendment to the Registration
        Statement filed subsequent to the date of this Agreement and also at
        each Time of Delivery, Ernst & Young LLP shall have furnished to you a
        letter or letters, dated the respective dates of delivery thereof, in
        form and substance satisfactory to you, to the effect set forth in Annex
        I hereto (the executed copy of the letter delivered prior to the
        execution of this Agreement is attached as Annex I(a) hereto and a draft
        of the form of letter to be delivered on the effective date of any
        post-effective amendment to the Registration Statement and as of each
        Time of Delivery is attached as Annex I(b) hereto);

               (g)    (i) Neither the Company nor any of the Subsidiaries shall
        have sustained since the date of the latest audited financial statements
        included in the Prospectus any loss or interference with its business
        from fire, explosion, flood or other calamity, whether or not covered by
        insurance, or from any labor dispute or court or governmental action,
        order or decree, otherwise than as set forth or contemplated in the
        Prospectus, and (ii) since the respective dates as of which information
        is given in the Prospectus there shall not have been any change in the
        share capital or long-term debt of the Company or any of the
        Subsidiaries or any change, or any development which could reasonably be
        expected to result in a prospective change, in or affecting the general
        affairs, management, financial position, shareholders' equity or results
        of operations of the Company and the Subsidiaries, otherwise than as set
        forth or contemplated in the Prospectus, the effect of which, in any
        such case described in clause (i) or (ii), is in the judgment of the
        representatives so material and adverse as to make it impracticable or
        inadvisable to proceed with the public offering or the delivery of the
        Shares being delivered at such Time of Delivery on the terms and in the
        manner contemplated in the


<PAGE>   20

        Prospectus;

               (h)    On or after the date hereof (i) no downgrading shall have
        occurred in the rating accorded the Company's debt securities by any
        "nationally recognized statistical rating organization", as that term is
        defined by the Commission for purposes of Rule 436(g)(2) under the Act,
        and (ii) no such organization shall have publicly announced that it has
        under surveillance or review, with possible negative implications, its
        rating of any of the Company's debt securities;

               (i)    On or after the date hereof there shall not have occurred
        any of the following: (i) a suspension or material limitation in trading
        in securities generally on the New York Stock Exchange, on NASDAQ or the
        Tel Aviv Stock Exchange; (ii) a suspension or material limitation in
        trading in the Company's securities on NASDAQ; (iii) a general
        moratorium on commercial banking activities in New York or the State of
        Israel declared by the relevant authorities; (iv) a change or
        development involving a prospective change in Israeli taxation affecting
        the Company, the Shares or the transfer thereof or the imposition of
        exchange controls by the United States or the State of Israel, if the
        effect of any such change or development specified in this clause (iv)
        in the judgment of the representatives makes it impracticable or
        inadvisable to proceed with the public offering or the delivery of the
        Shares being delivered at such Time of Delivery on the terms and in the
        manner contemplated in the Prospectus; or (v) the outbreak or escalation
        of hostilities involving the United States, the United Kingdom or the
        State of Israel or the declaration by the United States, the United
        Kingdom or the State of Israel of a national emergency or war, if the
        effect of any such event specified in this clause (v) in the judgment of
        the representatives makes it impracticable or inadvisable to proceed
        with the public offering or the delivery of the Shares being delivered
        at such Time of Delivery on the terms and in the manner contemplated in
        the Prospectus or (vi) the occurrence of any material adverse change in
        the existing financial, political or economic conditions in the United
        States and the State of Israel or elsewhere which, in the judgment of
        the representatives would materially and adversely affect the financial
        markets or the market for the Shares and other equity securities;

               (j)    The Shares to be sold by the Company at such Time of
        Delivery shall have been duly approved, subject to notice of issuance,
        for quotation on NASDAQ;

               (k)    The Company shall have complied with the provisions of
        Section 5(c) hereof with respect to the furnishing of prospectuses on
        the New York Business Day next succeeding the date of this Agreement;

               (l)    The Company shall have furnished or caused to be furnished
        to you at such Time of Delivery certificates of officers of the Company
        satisfactory to you as to the accuracy of the representations and
        warranties of the Company herein at and as of such Time of Delivery, as
        to the performance by the Company of all of their respective obligations
        hereunder to be performed at or prior to such Time of Delivery, and as
        to such other matters as you may reasonably request, and the Company
        shall have furnished or caused to be furnished certificates as to the
        matters set forth in subsections


<PAGE>   21

        (a) and (f) of this Section, and as to such other matters as you may
        reasonably request; and

               (m)    You shall have received the lock-up agreements in the form
        attached hereto as Annex III from all directors and executive officers
        of the Company and all Stockholders holding more than [__]% of the
        Company's share capital.

        8.     (a)    The Company and the U.S. Subsidiary will, jointly and
        severally, indemnify and hold harmless each Underwriter against any
        losses, claims, damages or liabilities, joint or several, to which such
        Underwriter may become subject, under the Act or otherwise, insofar as
        such losses, claims, damages or liabilities (or actions in respect
        thereof) arise out of or are based upon an untrue statement or alleged
        untrue statement of a material fact contained in any Preliminary
        Prospectus, the Registration Statement or the Prospectus, or any
        amendment or supplement thereto, or arise out of or are based upon the
        omission or alleged omission to state therein a material fact required
        to be stated therein or necessary to make the statements therein not
        misleading, and will reimburse each Underwriter for any legal or other
        expenses reasonably incurred by such Underwriter in connection with
        investigating or defending any such action or claim as such expenses are
        incurred; provided, however, that the Company and the U.S. Subsidiary
        shall not be liable in any such case to the extent that any such loss,
        claim, damage or liability arises out of or is based upon an untrue
        statement or alleged untrue statement or omission or alleged omission
        made in any Preliminary Prospectus, the Registration Statement or the
        Prospectus or any such amendment or supplement in reliance upon and in
        conformity with written information furnished to the Company by any
        Underwriter through Goldman, Sachs & Co. expressly for use therein.

               (b)    Each Underwriter will indemnify and hold harmless the
        Company and the U.S. Subsidiary against any losses, claims, damages or
        liabilities to which the Company or the U.S. Subsidiary may become
        subject, under the Act or otherwise, insofar as such losses, claims,
        damages or liabilities (or actions in respect thereof) arise out of or
        are based upon an untrue statement or alleged untrue statement of a
        material fact contained in any Preliminary Prospectus, the Registration
        Statement or the Prospectus, or any amendment or supplement thereto, or
        arise out of or are based upon the omission or alleged omission to state
        therein a material fact required to be stated therein or necessary to
        make the statements therein not misleading, in each case to the extent,
        but only to the extent, that such untrue statement or alleged untrue
        statement or omission or alleged omission was made in any Preliminary
        Prospectus, the Registration Statement or the Prospectus or any such
        amendment or supplement in reliance upon and in conformity with written
        information furnished to the Company by such Underwriter through
        Goldman, Sachs & Co. expressly for use therein; and will reimburse the
        Company and the U.S. Subsidiary for any legal or other expenses
        reasonably incurred by the Company or the U.S. Subsidiary in connection
        with investigating or defending any such action or claim as such
        expenses are incurred.

               (c)    Promptly after receipt by an indemnified party under
        subsection (a) or (b) above of notice of the commencement of any action,
        such indemnified party shall, if a claim in respect thereof is to be
        made against an indemnifying party under such


<PAGE>   22

        subsection, notify the indemnifying party in writing of the commencement
        thereof; but the omission so to notify the indemnifying party shall not
        relieve it from any liability which it may have to any indemnified party
        otherwise than under such subsection. In case any such action shall be
        brought against any indemnified party and it shall notify the
        indemnifying party of the commencement thereof, the indemnifying party
        shall be entitled to participate therein and, to the extent that it
        shall wish, jointly with any other indemnifying party similarly
        notified, to assume the defense thereof, with counsel satisfactory to
        such indemnified party (who shall not, except with the consent of the
        indemnified party, be counsel to the indemnifying party), and, after
        notice from the indemnifying party to such indemnified party of its
        election so to assume the defense thereof, the indemnifying party shall
        not be liable to such indemnified party under such subsection for any
        legal expenses of other counsel or any other expenses, in each case
        subsequently incurred by such indemnified party, in connection with the
        defense thereof other than reasonable costs of investigation. No
        indemnifying party shall, without the written consent of the indemnified
        party, effect the settlement or compromise of, or consent to the entry
        of any judgment with respect to, any pending or threatened action or
        claim in respect of which indemnification or contribution may be sought
        hereunder (whether or not the indemnified party is an actual or
        potential party to such action or claim) unless such settlement,
        compromise or judgment (i) includes an unconditional release of the
        indemnified party from all liability arising out of such action or claim
        and (ii) does not include a statement as to or an admission of fault,
        culpability or a failure to act, by or on behalf of any indemnified
        party.

               (d)    If the indemnification provided for in this Section 8 is
        unavailable to or insufficient to hold harmless an indemnified party
        under subsection (a) or (b) above in respect of any losses, claims,
        damages or liabilities (or actions in respect thereof) referred to
        therein, then each indemnifying party shall contribute to the amount
        paid or payable by such indemnified party as a result of such losses,
        claims, damages or liabilities (or actions in respect thereof) in such
        proportion as is appropriate to reflect the relative benefits received
        by the Company on the one hand and the Underwriters on the other from
        the offering of the Shares. If, however, the allocation provided by the
        immediately preceding sentence is not permitted by applicable law or if
        the indemnified party failed to give the notice required under
        subsection (c) above, then each indemnifying party shall contribute to
        such amount paid or payable by such indemnified party in such proportion
        as is appropriate to reflect not only such relative benefits but also
        the relative fault of the Company and the U.S. Subsidiary on the one
        hand and the Underwriters on the other in connection with the statements
        or omissions which resulted in such losses, claims, damages or
        liabilities (or actions in respect thereof), as well as any other
        relevant equitable considerations. The relative benefits received by the
        Company and the U.S. Subsidiary on the one hand and the Underwriters on
        the other shall be deemed to be in the same proportion as the total net
        proceeds from the offering of the Shares purchased under this Agreement
        (before deducting expenses) received by the Company bear to the total
        underwriting discounts and commissions received by the Underwriters with
        respect to the Shares purchased under this Agreement, in each case as
        set forth in the table on the cover page of the Prospectus. The relative
        fault shall be determined by reference to, among other things, whether
        the untrue or alleged untrue statement of a material fact or the
        omission or alleged omission to state a material fact




<PAGE>   23

        relates to information supplied by the Company on the one hand or the
        Underwriters on the other and the parties' relative intent, knowledge,
        access to information and opportunity to correct or prevent such
        statement or omission. The Company, the U.S. Subsidiary and the
        Underwriters agree that it would not be just and equitable if
        contributions pursuant to this subsection (d) were determined by pro
        rata allocation (even if the Underwriters were treated as one entity for
        such purpose) or by any other method of allocation which does not take
        account of the equitable considerations referred to above in this
        subsection (d). The amount paid or payable by an indemnified party as a
        result of the losses, claims, damages or liabilities (or actions in
        respect thereof) referred to above in this subsection (d) shall be
        deemed to include any legal or other expenses reasonably incurred by
        such indemnified party in connection with investigating or defending any
        such action or claim. Notwithstanding the provisions of this subsection
        (d), no Underwriter shall be required to contribute any amount in excess
        of the amount by which the total price at which the Shares underwritten
        by it and distributed to the public were offered to the public exceeds
        the amount of any damages which such Underwriter has otherwise been
        required to pay by reason of such untrue or alleged untrue statement or
        omission or alleged omission. No person guilty of fraudulent
        misrepresentation (within the meaning of Section 11(f) of the Act) shall
        be entitled to contribution from any person who was not guilty of such
        fraudulent misrepresentation. The Underwriters' obligations in this
        subsection (d) to contribute are several in proportion to their
        respective underwriting obligations and not joint.

               (e)    The obligations of the Company and the U.S. Subsidiary
        under this Section 8 shall be in addition to any liability which the
        Company or the U.S. Subsidiary may otherwise have and shall extend, upon
        the same terms and conditions, to each person, if any, who controls any
        Underwriter within the meaning of the Act; and the obligations of the
        Underwriters under this Section 8 shall be in addition to any liability
        which the respective Underwriters may otherwise have and shall extend,
        upon the same terms and conditions, to each officer and director of the
        Company or the U.S. Subsidiary (including any person who, with his or
        her consent, is named in the Registration Statement as about to become a
        director of the Company) and to each person, if any, who controls the
        Company or the U.S. Subsidiary within the meaning of the Act.

        9.     (a)    If any Underwriter shall default in its obligation to
        purchase the Shares which it has agreed to purchase hereunder at a Time
        of Delivery, you may in your discretion arrange for you or another party
        or other parties to purchase such Shares on the terms contained herein.
        If within thirty-six hours after such default by any Underwriter you do
        not arrange for the purchase of such Shares, then the Company shall be
        entitled to a further period of thirty-six hours within which to procure
        another party or other parties satisfactory to you to purchase such
        Shares on such terms. In the event that, within the respective
        prescribed periods, you notify the Company that you have so arranged for
        the purchase of such Shares, or the Company notify you that they have so
        arranged for the purchase of such Shares, you or the Company shall have
        the right to postpone such Time of Delivery for a period of not more
        than seven days, in order to effect whatever changes may thereby be made
        necessary in the Registration Statement or the Prospectus, or in any
        other documents or arrangements, and the Company agrees to file promptly
        any amendments to the Registration Statement or the


<PAGE>   24

        Prospectus which in your opinion may thereby be made necessary. The term
        "Underwriter" as used in this Agreement shall include any person
        substituted under this Section with like effect as if such person had
        originally been a party to this Agreement with respect to such Shares.

               (b)    If, after giving effect to any arrangements for the
        purchase of the Shares of a defaulting Underwriter or Underwriters by
        you and the Company as provided in subsection (a) above, the aggregate
        number of such Shares which remains unpurchased does not exceed
        one-eleventh of the aggregate number of all of the Shares to be
        purchased at such Time of Delivery, then the Company shall have the
        right to require each non-defaulting Underwriter to purchase the number
        of Shares which such Underwriter agreed to purchase hereunder at such
        Time of Delivery and, in addition, to require each non-defaulting
        Underwriter to purchase its pro rata share (based on the number of
        Shares which such Underwriter agreed to purchase hereunder) of the
        Shares of such defaulting Underwriter or Underwriters for which such
        arrangements have not been made; but nothing herein shall relieve a
        defaulting Underwriter from liability for its default.

               (c)    If, after giving effect to any arrangements for the
        purchase of the Shares of a defaulting Underwriter or Underwriters by
        you and the Company as provided in subsection (a) above, the aggregate
        number of such Shares which remains unpurchased exceeds one- eleventh of
        the aggregate number of all of the Shares to be purchased at such Time
        of Delivery, or if the Company shall not exercise the right described in
        subsection (b) above to require non-defaulting Underwriters to purchase
        Shares of a defaulting Underwriter or Underwriters, then this Agreement
        (or, with respect to the Second Time of Delivery, the obligations of the
        Underwriters to purchase and of the Company to sell the Optional Shares)
        shall thereupon terminate, without liability on the part of any
        non-defaulting Underwriter or the Company, except for the expenses to be
        borne by the Company and the Underwriters as provided in Section 6
        hereof and the indemnity and contribution agreements in Section 8
        hereof; but nothing herein shall relieve a defaulting Underwriter from
        liability for its default.

        10.    The respective indemnities, agreements, representations,
warranties and other statements of the Company and the U.S. Subsidiary and the
several Underwriters, as set forth in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement, shall remain in full force and
effect, regardless of any investigation (or any statement as to the results
thereof) made by or on behalf of any Underwriter or any controlling person of
any Underwriter, or the Company or the U.S. Subsidiary, or any officer or
director or controlling person of the Company or the U.S. Subsidiary, or any
controlling person, and shall survive delivery of and payment for the Shares.

        Anything herein to the contrary notwithstanding, the indemnity agreement
of the Company and the U.S. Subsidiary in subsection (a) of Section 8 hereof,
the representations and warranties in subsections (b) and (c) of Section 1
hereof and any representation or warranty as to the accuracy of the Registration
Statement or the Prospectus contained in any certificate furnished by the
Company pursuant to Section 7 hereof, insofar as they may constitute a basis for
indemnification for liabilities (other than payment by the Company of


<PAGE>   25

expenses incurred or paid in the successful defense of any action, suit or
proceeding) arising under the Act, shall not extend to the extent of any
interest therein of a controlling person or partner of an Underwriter who is a
director, officer or controlling person of the Company when the Registration
Statement has become effective, except in each case to the extent that an
interest of such character shall have been determined by a court of appropriate
jurisdiction as not against public policy as expressed in the Act. Unless in the
opinion of counsel for the Company the matter has been settled by controlling
precedent, the Company will, if a claim for such indemnification is asserted,
submit to a court of appropriate jurisdiction the question of whether such
interest is against public policy as expressed in the Act and will be governed
by the final adjudication of such issue.

        11.    If this Agreement shall be terminated pursuant to Section 9
hereof, the Company and the U.S. Subsidiary shall not then be under any
liability to any Underwriter except as provided in Sections 6 and 8 hereof; but,
if for any other reason any Shares are not delivered by or on behalf of the
Company as provided herein, the Company will reimburse the Underwriters through
you for all out-of-pocket expenses approved in writing by you, including fees
and disbursements of counsel, reasonably incurred by the Underwriters in making
preparations for the purchase, sale and delivery of the Shares not so delivered,
but the Company and the U.S. Subsidiary shall then be under no further liability
to any Underwriter in respect of the Shares not so delivered except as provided
in Sections 6 and 8 hereof.

        12.    In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives.

        All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 32 Old Slip, 21st Floor, New York, New York 10005, Attention: Registration
Department; and if to the Company shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Company set forth in the
Registration Statement, Attention: Chief Financial Officer; provided, however,
that any notice to an Underwriter pursuant to Section 8 (c) hereof shall be
delivered or sent by mail, telex or facsimile transmission to such Underwriter
at its address set forth in its Underwriters' Questionnaire or telex
constituting such Questionnaire, which address will be supplied to the Company
by you upon request. Any such statements, requests, notices or agreements shall
take effect upon receipt thereof.

        13.    This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Company, the U.S. Subsidiary and, to the
extent provided in Sections 8 and 10 hereof, the officers and directors of the
Company and each person who controls the Company, the U.S. Subsidiary or any
Underwriter, and their respective heirs, executors, administrators, successors
and assigns, and no other person shall acquire or have any right under or by
virtue of this Agreement. No purchaser of any of the Shares from any Underwriter
shall be deemed a successor or assign by reason merely of such purchase.

        14.    Each of the parties hereto irrevocably (i) agrees that any legal
suit, action or


<PAGE>   26

proceeding arising out of or based upon this Agreement or the transactions
contemplated hereby may be instituted in any Federal or State Court in the City
of New York, (ii) waives, to the fullest extent it may effectively do so, any
objection which it may now or hereafter have to the laying of venue of any such
proceeding and (iii) submits to the exclusive jurisdiction of such courts in any
such suit, action or proceeding. The Company hereby designates and appoints the
U.S. Subsidiary, as its authorized agent (the "Authorized Agent") upon whom
process may be served in any such action arising out of or based on this
Agreement or the transactions contemplated hereby which may be instituted in any
New York Court by any Underwriter or by any person who controls any Underwriter,
expressly consents to the jurisdiction of any such court in respect of any such
action, and waives any other requirements of or objections to personal
jurisdiction with respect thereto. Such appointment shall be irrevocable unless
and until a successor authorized agent acceptable to the Underwriters in their
sole and absolute discretion shall have been appointed by the Company.. The
Company represents and warrants that the Authorized Agent has agreed to act as
such agent for service at process and agrees to take any and all action,
including the filing of any and all documents and instruments, that may be
necessary to continue such appointment in full force and effect as aforesaid.
Service of process upon the Authorized Agent and written notice of such service
to the Company shall be deemed, in every respect, effective service of process
upon the Company.

        15.    In respect of any judgment or order given or made for any amount
due hereunder that is expressed and paid in a currency (the "judgment currency")
other than United States dollars, the Company, as the case may be, will
indemnify each Underwriter against any loss incurred by such Underwriter as a
result of any variation as between (i) the rate of exchange at which the United
States dollar amount is converted into the judgment currency for the purpose of
such judgment or order and (ii) the rate of exchange at which such Underwriter
on the date such judgment currency is actually received by the Underwriter is
able to purchase United States dollars with the amount of the judgment currency
so received by such Underwriter. The foregoing indemnity shall constitute a
separate and independent obligation of the Company and shall continue in full
force and effect notwithstanding any such judgment or order as aforesaid. The
term "rate of exchange" shall include any premiums and costs of exchange payable
in connection with the purchase of or conversion into United States dollars.

        16.    Time shall be of the essence of this Agreement. As used herein,
the term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

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

        18.    This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.


<PAGE>   27


        If the foregoing is in accordance with your understanding, please sign
and return to us [__] counterparts hereof, and upon the acceptance hereof by
you, on behalf of each of the Underwriters, this letter and such acceptance
hereof shall constitute a binding agreement among each of the Underwriters, the
Company and the U.S. Subsidiary. It is understood that your acceptance of this
letter on behalf of each of the Underwriters is pursuant to the authority set
forth in a form of Agreement among Underwriters, the form of which shall be
submitted to the Company for examination upon request, but without warranty on
your part as to the authority of the signers thereof.

                                        Very truly yours,

                             THE COMPANIES ORDINANCE

                           A COMPANY LIMITED BY SHARES


                             ARTICLES OF ASSOCIATION

                                       OF

                            BACKWEB TECHNOLOGIES LTD.
                                 (the "Company")



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



                                   PRELIMINARY


1.       Table "A" Excluded

                The regulations contained in the second schedule to the
Companies Ordinance (New Version), 5743-1983 (the "Companies Ordinance") shall
not apply to the Company.


2.      Public Company

                This Company is a Public Company, as such term is defined in the
Companies Ordinance.



                                  SHARE CAPITAL


3.      Share Capital

                (a) The authorized share capital of the Company is NIS
6,002,034.88, divided into 50,000,000 (fifty million) Preferred Shares of
undesignated series ("Preferred Shares"), nominal value NIS 0.03 per share (or
such other nominal value recommended by the Board of Directors), 150,000,000
(One hundred fifty million)



<PAGE>   2

Ordinary Shares, nominal value NIS 0.03 per share, and 1 (one) Series E
Preferred Share, nominal value NIS 0.01 ("Series E Preferred").

                (b) The Preferred Shares may be issued from time to time as
shares of one or more series, with such distinctive serial designations as may
be stated or expressed in the resolution or resolutions providing for the
issuance of such shares from time to time adopted by the Board of Directors of
the Company. In the resolution or resolutions providing for the issuance of such
shares, the Board of Directors of the Company is expressly authorized, without
the need for shareholder action, to fix the terms and preferences of the shares
of such series, including without limitation the dividend rate, the redemption
price, the voting rights, the right or obligation of the Company to redeem the
shares, and the terms upon which the shares are convertible into or exchangeable
for shares of any other class or classes.

                (c) The Ordinary Shares all rank pari passu.

                (d) The Series E Preferred shall have the rights, preferences,
privileges and restrictions granted to and imposed on the Series E Preferred as
may be specifically indicated herein and/or as the context may so reasonably
require. The registered holder of the Series E Preferred Share shall be entitled
to have a number of votes equal to the number of outstanding exchangeable shares
of BackWeb Canada Inc. (the BackWeb Canada Exchangeable Shares"), a corporation
incorporated under the laws of Ontario, Canada and a subsidiary of the Company,
from time to time (excluding those owned by the Company and its affiliates which
are corporations or partnerships or other like entities), and with respect to
such votes, such holder shall have full voting rights and powers equal to the
voting rights and powers of the holders of that same number of Ordinary Shares,
and shall be entitled, notwithstanding any provision hereof, to notice of any
shareholders' meeting in accordance with the Articles of Association of the
Company, and shall be entitled to vote, together with holders of Ordinary
Shares, for the election of directors and with respect to any question upon
which holders of Ordinary Shares have the right to vote. The holder of the
Series E Preferred shall not be entitled to receive any dividends declared and
paid by the Company. On such date as no BackWeb Canada Exchangeable Shares
remain outstanding and there are no securities, or other agreements of BackWeb
Canada Inc. which could give rise to the issuance of any BackWeb Canada
Exchangeable Shares to any person (other than the Company or its affiliates
which are corporations or partnerships or other like entities), the Series E
Preferred shall be canceled and shall have no further rights. Upon liquidation,
dissolution or winding up of the Company, the holder of the Series E Preferred
shall be entitled to receive only the par value of the Series E Preferred, 0.01
NIS, subject to any prior rights of holders of Preferred Shares and in parity
with the holders of Ordinary Shares.


4.      Increase of Authorized Share Capital



                                       2
<PAGE>   3

                (a) The Company may, from time to time, by Special Resolution,
whether or not all the shares then authorized have been issued, and whether or
not all the shares previously issued have been called up for payment, increase
its authorized share capital. Any such increase shall be in such amount and
shall be divided into shares of such nominal amounts, and such shares shall
confer such rights and preferences, and shall be subject to such restrictions,
as such Special Resolution shall provide.

                (b) Except to the extent otherwise provided in such Special
Resolution, any new shares included in the authorized share capital so increased
shall be subject to all the provisions of these Articles which are applicable to
shares of such class included in the existing share capital without regard to
class (and, if such new shares are of the same class as a class of shares
included in the existing share capital, to all of the provisions which are
applicable to shares of such class included in the existing share capital).


5.      Special Rights; Modification of Rights

                (a) Subject to the provisions of the Memorandum of Association
of the Company, and without prejudice to any special rights previously conferred
upon the holders of existing shares in the Company, the Company may, from time
to time, by Special Resolution, provide for shares with such preferred or
deferred rights or rights of redemption, or other special rights and/or such
restrictions, whether in regard to dividends, voting repayment of share capital
or otherwise, as may be stipulated in such Special Resolution.

                (b) (i) If at any time the share capital is divided into
different classes of shares, the rights attached to any class, unless otherwise
provided by these Articles, may be modified or abrogated by the Company, by
Special Resolution, subject to the consent in writing of the holders of
seventy-five percent (75%) of the issued shares of such class.

                        (ii) The provisions of these Articles relating to
General Meetings shall, mutatis mutandis, apply to any separate General Meeting
of the holders of the shares of a particular class; provided, however, that the
requisite quorum at any such separate General Meeting shall be two or more
members present in person or proxy and holding not less than seventy-five
percent (75%) of the issued shares of such class.

                        (iii) Unless otherwise provided by these Articles, the
enlargement of an authorized class of shares, or the issuance of additional
shares thereof out of the authorized and unissued share capital, shall not be
deemed, for purposes of this Article 5(b), to modify or abrogate the rights
attached to previously issued shares of such class or of any other class.


6.      Consolidation, Subdivision, Cancellation and Reduction of Share Capital



                                       3
<PAGE>   4

                (a) The Company may, from time to time, by Special Resolution
(subject, however, to the provisions of Article 5(b) hereof and to applicable
law):

                        (i) consolidate and divide all or any part of its issued
or unissued authorized share capital into shares of a per share nominal value
which is larger than the per share nominal value of its existing shares;

                        (ii) subdivide its shares (issued or unissued) or any of
them, into shares of smaller nominal value than is fixed by the Memorandum of
Association (subject, however, to the provisions of Section 144(4) of the
Companies Ordinance);

                        (iii) cancel any shares which, at the date of the
adoption of such Special Resolution, have not been taken or agreed to be taken
by any person, and diminish the amount of its share capital by the amount of the
shares so cancelled; or

                        (iv) reduce its share capital in any manner, subject to
any consent required by law.

                (b) With respect to any consolidation of issued shares of a
larger nominal value per share, and with respect to any other action which may
result in fractional shares, the Board of Directors may settle any difficulty
which may arise with regard thereto, as it deems fit, and in connection with any
such consolidation or other action which would result in fractional shares may,
without limiting its power:

                        (i) determine, as to the holder of the shares so
consolidated, which issued shares shall be consolidated into a share of a larger
nominal value per share;

                        (ii) allot, in contemplation of or subsequent to such
consolidation or other action, shares or fractional shares sufficient to
preclude or remove fractional share holdings;

                        (iii) redeem, in the case of redeemable preference
shares and subject to applicable law, such fractional shares sufficient to
preclude or remove fractional share holdings;

                        (iv) cause the transfer of fractional shares by certain
shareholders of the Company to other shareholders so as to most expediently
preclude or remove any fractional shareholdings, and cause the transferees of
such fractional shares to pay the transferors thereof the fair value thereof,
and the Board of Directors is hereby authorized to act in connection with such
transfer as agent for the transferors and transferees of any such fractional
shares, with full power of substitution, for the purposes of implementing the
provisions of this sub-Article 6(b)(iv).

                (a) Share certificates shall be issued under the corporate seal
of the Company and shall bear the signature of one Director, or of any other
person or persons authorized by the Board of Directors.

                (b) Each member shall be entitled to one numbered certificate
for all the shares of any class registered in his name, and if the Board of
Directors so approves, to several certificates, each for one or more of such
shares. Each certificate shall specify the serial numbers of the shares
represented thereby and may also specify the amount paid up thereon.

                (c) A share certificate registered in the names of two or more
persons shall be delivered to the person first named in the Register of Members
in respect of such co-ownership.

                (d) A share certificate which has been defaced, lost or
destroyed may be replaced, and the Company shall issue a new certificate to
replace such defaced, lost or destroyed certificate, upon payment of such fee,
and upon the furnishing of such evidence of ownership and such indemnity, as the
Board of Directors in its discretion deems fit.


8.      Registered Holder

                Except as otherwise provided in these Articles, the Company
shall be entitled to treat the registered holder of each share as the absolute
owner thereof, and accordingly shall not, except as ordered by a court of
competent jurisdiction or as required by statute, be obligated to recognize any
equitable or other claim to, or interest in, such share on the part of any other
person.


9.      Allotment of Shares

                The unissued shares from time to time shall be under the control
of the Board of Directors. The Board of Directors shall have the power to allot,
issue or otherwise dispose of shares to such persons, on such terms and
conditions (including terms relating to calls as set forth in Article 11(f)
hereof), and either at par or at a premium, or, subject to the provisions of the
Companies Ordinance, at a discount and/or with payment of commission, and at
such times, as the Board of Directors deems fit. The



                                       5
<PAGE>   6

Board of Directors shall also have the power to give to any person the option to
acquire from the Company any shares, either at par or at a premium, or, subject
as aforesaid, at a discount and/or with payment of commission, during such time
and for such consideration as the Board of Directors deems fit.


10.     Payment in Installments

                If, pursuant to the terms of the allotment or issue of any
share, all or any portion of the price thereof shall be payable in installments,
every such installment shall be paid to the Company on the due date thereof by
the then registered holder(s) of the share or the person(s) then entitled
thereto.


11.     Calls on Shares

                (a) The Board of Directors may, from time to time, as it in its
discretion deems fit, make calls for payment upon members in respect of any sum
which has not been paid up in respect of shares held by such members and which
is not, pursuant to the terms of allotment or issue of such shares or otherwise,
payable at a fixed time, and each member shall pay the amount of every call so
made upon him (and of each installment thereof if the same is payable in
installments) to the person(s) and at the time(s) and place(s) designated by the
Board of Directors, as any such time(s) may be thereafter extended and/or such
person(s) or place(s) changed. Unless otherwise stipulated in the resolution of
the Board of Directors (and in the notice hereafter referred to), each payment
in response to a call shall be deemed to constitute a pro rata payment on
account of all the shares in respect of which such call was made.

                (b) Notice of any call for payment by a member shall be given in
writing to such member not less than fourteen (14) days prior to the time of
payment fixed in such notice, and shall specify the time and place of payment,
and the person to whom such payment is to be made. Prior to the time for any
such payment fixed in a notice of a call given to a member, the Board of
Directors may in its absolute discretion, by notice in writing to such member,
revoke such call in whole or in part, or stipulate different place of payment or
person to whom payment is to be made. In the event of a call payable in
installments, only one notice thereof need be given.

                (c) If, pursuant to the terms of allotment or issue of a share
or otherwise, an amount is made payable at a fixed time (whether on account of
such share or by way of premium), such amount shall be payable at such time as
if it were payable by virtue of a call made by the Board of Directors and for
which notice was given in accordance with paragraphs (a) and (b) of this Article
11, and the provisions of these Articles with regard to calls (and the
non-payment thereof) shall be applicable to such amount (and the non-payment
thereof).



                                       6
<PAGE>   7

                (d) Joint holders of a share shall be jointly and severally
liable to pay all calls for payment in respect of such share and all interest
payable thereon.

                (e) Any amount called for payment which is not paid when due
shall bear interest from the date fixed for payment until actual payment
thereof, at such rate (not exceeding the then prevailing debitory rate charged
by leading commercial banks in Israel) and payable at such time(s) as the Board
of Directors may prescribe.

                (f) Upon the allotment of shares, the Board of Directors may
provide for differences among the allottees of such shares as to the amounts and
times for payment of calls for payment in respect of such shares.


12.     Prepayment

                With the approval of the Board of Directors, any member may pay
to the Company any amount not yet payable in respect of his shares, and the
Board of Directors may approve the payment by the Company of interest on any
such amount until the same would be payable if it had not been paid in advance,
at such rate and time(s) as may be approved by the Board of Directors. The Board
of Directors may at any time cause the Company to repay all or any part of the
money so advanced, without premium or penalty. Nothing in this Article 12 shall
derogate from the right of the Board of Directors to make any call for payment
before or after receipt by the Company of any such advance.


13.     Forfeiture and Surrender

                (a) If any member fails to pay an amount payable by virtue of a
call, or interest thereon as provided for in these Articles, on or before the
day fixed for payment of the same, the Board of Directors may, at any time after
the day fixed for such payment, so long as such amount (or any portion thereof)
or interest thereon (or any portion thereof) remains unpaid, forfeit all or any
of the shares in respect of which such payment was called. All expenses incurred
by the Company in attempting to collect any such amount or interest thereon,
including without limitation attorneys' fees and costs of legal proceedings,
shall be added to, and shall for all purposes (including the accrual of interest
thereon) constitute a part of, the amount payable to the Company in respect of
such call.

                (b) Upon the adoption of a resolution as to the forfeiture of a
member's share, the Board of Directors shall cause notice thereof to be given to
such member, which notice shall state that, in the event of the failure to pay
the entire amount so payable by a date specified in the notice (which date shall
be not less than fourteen (14) days after the date such notice is given and
which may be extended by the Board of Directors), such shares shall be ipso
facto forfeited; provided, however, that prior to such date, the Board of
Directors may nullify such resolution of forfeiture, but no such



                                       7
<PAGE>   8

nullification shall stop the Board of Directors from adopting a further
resolution of forfeiture in respect of the non-payment of the same amount.

                (c) Without derogating from Articles 54 and 59 hereof, whenever
shares are forfeited as herein provided, all dividends, if any, previously
declared in respect thereof and not actually paid shall be deemed to have been
forfeited at the same time.

                (d) The Company, by resolution of the Board of Directors, may
accept the voluntary surrender of any share.

                (e) Any share forfeited or surrendered as provided herein shall
become the property of the Company, and the same, subject to the provisions of
these Articles, may be sold, re-allotted or otherwise disposed of as the Board
of Directors deems fit.

                (f) Any member whose shares have been forfeited or surrendered
shall cease to be a member in respect of the forfeited or surrendered shares,
but shall nevertheless be liable to pay, and shall immediately pay to the
Company, all calls, interest and expenses owing on or in respect of such shares
at the time of forfeiture or surrender, together with interest thereon from the
time of forfeiture or surrender until actual payment, at the rate prescribed in
Article 11(e) above. The Board of Directors in its discretion may, but shall not
be obligated to, enforce the payment of such moneys or any part thereof. In the
event of such forfeiture or surrender, the Company, by resolution of the Board
of Directors, may accelerate the date(s) of payment of any or all amounts then
owing to the Company by the member in question (but not yet due) in respect of
all shares owned by such member, solely or jointly with another.

                (g) The Board of Directors may at any time, before any share so
forfeited or surrendered shall have been sold, re-allotted or otherwise disposed
of, nullify the forfeiture or surrender on such conditions as it deems fit, but
no such nullification shall stop the Board of Directors from re-exercising its
powers of forfeiture pursuant to this Article 13.


14.     Lien

                (a) Except to the extent the same may be waived or subordinated
in writing, the Company shall have a first and paramount lien upon all the
shares registered in the name of each member (without regard to any equitable or
other claim or interest in such shares on the part of any other person), and
upon the proceeds of the sale thereof, for his debts, liabilities and
obligations to the Company arising from any amount payable by such member in
respect of any unpaid or partly paid share, whether or not such debt, liability
or obligation has matured. Such lien shall extend to all dividends from time to
time declared or paid in respect of such share. Unless otherwise provided, the
registration by the Company of a transfer of shares shall be deemed to be a
waiver on the part of the Company of the lien (if any) existing on such shares
immediately prior to such transfer.



                                       8
<PAGE>   9

                (b) The Board of Directors may cause the Company to sell a share
subject to such a lien when the debt, liability or obligation giving rise to
such lien has matured, in such manner as the Board of Directors deems fit, but
no such sale shall be made unless such debt, liability or obligation has not
been satisfied within fourteen (14) days after written notice of the intention
to sell shall have been served on such member, his executors or administrators.

                (c) The net proceeds of any such sale, after payment of the
costs thereof, shall be applied in or toward satisfaction of the debts,
liabilities or obligations of such member in respect of such share (whether or
not the same have matured), and the residue (if any) shall be paid to the
member, his executors, administrators or assigns.


15.     Sale after Forfeiture or Surrender or in Enforcement of Lien

                Upon any sale of a share after forfeiture or surrender or for
enforcing a lien, the Board of Directors may appoint any person to execute an
instrument of transfer of the share so sold and cause the purchaser's name to be
entered in the Register of Members in respect of such share. The purchaser shall
be registered as the shareholder and shall not be bound to see to the regularity
of the sale proceedings, or to the application of the proceeds of such sale, and
after his name has been entered in the Register of Members in respect of such
share the validity of the sale shall not be impeached by any person and the
remedy of any person aggrieved by the sale shall be in damages only and against
the Company exclusively.


16.     Redeemable Shares

                The Company may, subject to applicable law, issue redeemable
shares and redeem the same.


17.     Conversion of Shares into Stock

                (a) The Board of Directors may, with the sanction of the members
previously given by Special Resolution, convert any paid-up shares into stock,
and may with like sanction reconvert any stock into paid-up shares of any
denomination.

                (b) The holders of stock may transfer the same, or any part
thereof, in the same manner and subject to the same regulations as the shares
from which the stock arose might have been transferred prior to conversion, or
as near thereto as circumstances admit; provided, however, that the Board of
Directors may from time to time fix the minimum amount of stock so transferable,
and restrict or forbid the transfer of fractions



                                       9
<PAGE>   10

of such minimum, but the minimum shall not exceed the nominal value of each of
the shares from which such stock arose.

                (c) The holders of stock shall, in accordance with the amount of
stock held by them, have the same rights and privileges as regards the minimum
amount of stock so transferable, and restrict or forbid the transfer of
fractions of such minimum, but the minimum shall not exceed the nominal value of
each of the shares from which such stock arose.

                (d) The holders of stock shall, in accordance with the amount of
stock held by them, have the same rights and privileges as regards dividends,
voting at meetings of the Company and other matters as if they held the shares
from which such stock arose, but no such right or privilege except participation
in the dividends and profits of the Company shall be conferred by any such
aliquot part of such stock as would not, if existing in shares, have conferred
that right or privilege.

                (e) Such of the Articles of the Company as are applicable to
paid-up shares shall apply to stock, and the words "share" and "shareholder" (or
"member") therein shall include "stock" and "stockholder."



                               TRANSFER OF SHARES


18.     Registration of Transfer

                (a) No transfer of shares shall be registered unless a proper
writing or instrument of transfer (in any customary form or any other form
satisfactory to the Board of Directors) has been submitted to the Company (or
its transfer agent), together with the share certificate(s) and such other
evidence of title as the Board of Directors may reasonably require. Until the
transferee has been registered in the Register of Members in respect of the
shares so transferred, the Company may continue to regard the transferor as the
owner thereof.

                (b) The Board of Directors may, in its discretion to the extent
it deems necessary, close the Register of Members for registrations of transfers
of shares during any year for a period determined by the Board of Directors, and
no registrations of transfers of shares shall be made by the Company during any
such period during which the Register of Members is so closed.


19.     Record Date for Notices of General Meetings



                                       10
<PAGE>   11

                Notwithstanding any other contrary provision of these Articles,
the Board of Directors may fix a date, not exceeding ninety (90) days prior to
the date of any General Meeting, as the date as of which shareholders entitled
to notice of and to vote at such meetings shall be determined, and all persons
who were holders of record of voting shares on such date and no others shall be
entitled to notice of and to vote at such meeting.



                             TRANSMISSION OF SHARES


20.     Decedent's Shares

                (a) In case of a share registered in the names of two or more
holders, the Company may recognize the survivor(s) as the sole owner(s) thereof
unless and until the provisions of Article 21(b) have been effectively invoked.

                (b) Any person becoming entitled to a share in consequence of
the death of any person, upon producing evidence of the grant of probate or
letters of administration or declaration of succession (or such other evidence
as the Board of Directors may reasonably deem sufficient), shall be registered
as a member in respect of such share, or may, subject to the regulations as to
transfer contained in these Articles, transfer such share.


21.     Receivers and Liquidators

                (a) The Company may recognize any receiver, liquidator or
similar official appointed to wind-up, dissolve or otherwise liquidate a
corporate member, and a trustee, manager, receiver, liquidator or similar
official appointed in bankruptcy or in connection with the reorganization of, or
similar proceeding with respect to, a member or its properties, as being
entitled to the shares registered in the name of such member.

                (b) Such receiver, liquidator or similar official appointed to
wind-up, dissolve or otherwise liquidate a corporate member and such trustee,
manager, receiver, liquidator, or similar official appointed in bankruptcy or in
connection with the reorganization of, or similar proceedings with respect to, a
member or its properties, upon producing such evidence as the Board of Directors
may deem sufficient to his authority to act in such capacity or under this
Article, shall with the consent of the Board of Directors (which the Board of
Directors may grant or refuse in its absolute discretion), be registered as a
member in respect of such shares, or may, subject to the regulations as to
transfer contained in these Articles, transfer such shares.

                (a) Notwithstanding any other provision of these Articles, the
Company shall not engage in any business combination with any interested
shareholder for a period of three years following the time that such shareholder
became an interested shareholder, unless:

                        (1) prior to such time the Board of Directors of the
Company approved either the business combination or the transaction which
resulted in the shareholder becoming an interested shareholder, or

                        (2) upon consummation of the transaction which resulted

partner or is, directly or indirectly, the owner of 20% or more of any class of
voting share, (ii) any trust or other estate in which such person has at least a
20% beneficial interest or as to which such person serves as trustee or in a
similar fiduciary capacity, and (iii) any relative or spouse of such person, or

caused by an interested shareholder and as a



                                       12
<PAGE>   13

result of such merger or consolidation subsection (a) of this Article is not
applicable to the surviving entity;

                                (ii) any sale, lease, exchange, mortgage,

transactions), except proportionately as a shareholder of such Company to or
with the interested shareholder, whether as part of a dissolution or otherwise,
of assets of the Company or of any direct or indirect majority owned subsidiary
of the Company, which assets have an aggregate market value equal to 10% or more
of either the aggregate market value of all of the assets of the Company
determined on a consolidated basis or the aggregate market value of all of the
outstanding shares of the Company;

                                (iii) any transaction which results in the

conversion of securities exercisable for or convertible into shares of the
Company or any such subsidiary, which securities were outstanding prior to the
time that the interested shareholder became such, (B) pursuant to a dividend or
distribution paid or made, or the exercise, exchange or conversion of securities

fractional share adjustments or as a result of any purchase or redemption of any
shares not caused, directly or indirectly, by the interested shareholder; or

                                (v) any receipt by the interested shareholder of
the benefit, directly or indirectly (except proportionately as a shareholder of
such Company), of any loans, advances, guarantees, pledges or any other

<PAGE>   14

through the ownership of voting shares, by contract or otherwise. A person who
is the owner of 20% or more of the outstanding voting shares of any corporation,
partnership, unincorporated association or other entity shall be presumed to
have control of such entity. Notwithstanding the foregoing, a presumption of
control shall not apply where such person holds voting shares in good faith and
not for the purpose of circumventing this Article as an agent, bank, broker,
nominee, custodian or trustee for one or more owners who do not individually or
as a group have control of such entity.

                        (5) "interested shareholder" means any person (other
than the Company and any direct or indirect majority owned subsidiary of the
Company) that (i) is the owner of 15% or more of the outstanding voting shares
of the Company, or (ii) is an affiliate or associate of the Company and was the
owner of 15% or more of the outstanding voting shares of the Company at any time
within the three year period immediately prior to that date on which it is
sought to be determined whether such person is an interested shareholder and the
affiliates and associates of such person. For the purpose of determining whether
a person is an interested shareholder, the voting shares of the Company deemed
to be outstanding shall include shares deemed to be owned by the person through
application of paragraph (8) of this subsection but shall not include any other
unissued shares of the Company which may be issuable pursuant to any agreement,
arrangement or understanding, or upon exercise of conversion rights, warrants or
options, or otherwise.

                        (6) "person" means any individual, corporation,
partnership, unincorporated association or other entity.

                        (7) "share" means with respect to any corporation shares
of its capital and with respect to any other entity any equity interest.

                        (8) "voting shares" means with respect to any
corporation shares of any class or series entitled to vote generally in the
election of directors and, with respect to any entity that is not a corporation,
any equity interest entitled to vote generally in the election of the governing
body of such entity.

                        (9) "owner," including the terms "own" and "owned," when
used with respect to any share, means a person that individually or with or
through any of its affiliates or associates:

                                (i) beneficially owns such share, directly or
indirectly: or

                                (ii) has (A) the right to acquire such share
(whether such right is exercisable immediately or only after the passage of
time) pursuant to any agreement, arrangement or understanding or upon the
exercise of conversion rights, warrants or options, or otherwise; provided,
however, that a person shall not be deemed the owner of share tendered pursuant
to a tender or exchange; or (B) the right to vote such share pursuant to any
agreement, arrangement or understanding; provided, however, that a



                                       14
<PAGE>   15

person shall not be deemed the owner of any share because of such person's right
to vote such share if the agreement, arrangement, or understanding to vote such
share arises solely from a recoverable proxy or consent given in response to a
proxy or consent solicitation made to 10 or more persons: or

                                (iii) has any agreement, arrangement or
understanding for the purpose of acquiring, holding, voting (except voting
pursuant to a revocable proxy or consent as described in item (B) of clause (ii)
of this paragraph) or disposing of such share with any other person that
beneficially owns or whose affiliates or associates beneficially own, directly
or indirectly, such share.

23.     Annual General Meeting

                An Annual General Meeting shall be held once in every calendar

out of the State of Israel, as may be determined by the Board of Directors.


24.     Extraordinary General Meetings

                All General Meetings other than Annual General Meetings shall be
called "Extraordinary General Meetings." The Board of Directors may, whenever it
thinks fit, convene an Extraordinary General Meeting, at such time and place,
within or out of the State of Israel, as may be determined by the Board of
Directors, and shall be obliged to do so upon a request in writing in accordance
with Section 109 of the Companies Ordinance.

                (a) Not less than seven (7) days' prior notice shall be given of
every General Meeting; provided, however, that a Special Resolution shall not be
passed unless at least twenty-one (21) days' prior notice shall have been given
of the meeting at which it is proposed to pass the same. Each such notice shall
specify the place and the day and hour of the meeting and the general nature of
each item to be acted upon, such notice to be given to all members who would be
entitled to attend and vote at such meeting. Anything herein to the contrary
notwithstanding, with the consent of all members entitled to vote thereon a
resolution may be proposed and passed at such meeting although a lesser notice
than prescribed above has been given.

<PAGE>   16

                (b) The accidental omission to give notice of a meeting to any
member, or the non-receipt of notice sent to such member, shall not invalidate
the proceedings at such meeting.



                         PROCEEDINGS AT GENERAL MEETINGS


26.     Quorum

                (a) No business shall be transacted at a General Meeting, or at
any adjournment thereof, unless the quorum required under these Articles for
such General Meeting or such adjourned meeting, as the case may be, is present
when the meeting proceeds to business.

                (b) In the absence of contrary provisions in these Articles, two
or more members (not in default in payment of any sum referred to in Article
32(a) hereof), present in person or by proxy and holding shares conferring in
the aggregate more than fifty percent of the voting power of the Company, shall
constitute a quorum of General Meetings.

                (c) If within half an hour from the time appointed for the
meeting a quorum is not present, the meeting, if convened upon request under
Section 109 of the Companies Ordinance, shall be dissolved, but in any other
case it shall be adjourned to the same day in the next week, at the same time
and place, or to such day and at such time and place as the Chairman may
determine with the consent of the holders of a majority of the shares present in
person or by proxy and voting on the question of adjournment. No business shall
be transacted at any adjourned meeting except business which might lawfully have
been transacted at the meeting as originally called. At such adjourned meeting
(other than an adjourned separate meeting of a particular class of shares as
referred to in Article 5 of these Articles), any two (2) members (not in default
as aforesaid) present in person or by proxy shall constitute a quorum.


27.     Chairman

                The Chairman, if any, of the Board of Directors shall preside as
Chairman at every General Meeting of the Company. If at any meeting the Chairman
is not present within fifteen (15) minutes after the time fixed for holding the
meeting or is unwilling to act as Chairman, the Co-Chairman shall preside at the
meeting. If at any such meeting both the Chairman and the Co-Chairman are not
present or are unwilling to act as Chairman, members present shall choose
someone of their number to be Chairman. The office of Chairman shall not, by
itself, entitle the holder thereof to vote at any General Meeting nor shall it
entitle such holder to a second or casting vote (without derogating,



                                       16
<PAGE>   17

however from the rights of such Chairman to vote as a shareholder or proxy of a
shareholder if, in fact, he is also a shareholder or such proxy).


28.     Adoption of Resolutions at General Meetings

                (a) (i) An Ordinary Resolution shall be deemed adopted if
approved by the holders of a majority of the voting power represented at the
meeting in person or by proxy and voting thereon.

                        (ii) A Special or Extraordinary Resolution shall be
deemed adopted if approved by the holders of not less then seventy-five per cent
(75%) of the voting power represented at the meeting in person or by proxy and
voting thereon.

                (b) Every question submitted to a General Meeting shall be
decided by a show of hands, but if a written ballot is demanded by any member
present in person or by proxy and entitled to vote at the meeting, the same
shall be decided by such ballot. A written ballot may be demanded before the
proposed resolution is voted upon or immediately after the declaration by the
Chairman of the results of the vote by a show of hands. If a vote by written
ballot is taken after such declaration, the results of the vote by a show of
hands shall be of no effect, and the proposed resolution shall be decided by
such written ballot. The demand for a written ballot may be withdrawn at any
time before the same is conducted, in which event another member may then demand
such written ballot. The demand for a written ballot shall not prevent the
continuance of the meeting for the transaction of business other than the
question on which the written ballot has been demanded.

                (c) A declaration by the Chairman of the meeting that a
resolution has been carried unanimously, or carried by a particular majority, or
lost, and an entry to that effect in the minute book of the Company, shall be
conclusive evidence of the fact without proof of the number or proportion of the
votes recorded in favor of or against such resolution.


29.     Resolutions in Writing

                A resolution in writing signed by all members of the Company
then entitled to attend and vote at General Meetings or to which all such
members have given their written consent (by letter, telegram, telex, facsimile
or otherwise) shall be deemed to have been unanimously adopted by a General
Meeting duly convened and held.


30.     Power to Adjourn



                                       17
<PAGE>   18

                The Chairman of a General Meeting at which a quorum is present
may, with the consent of the holders of a majority of the voting power
represented in person or by proxy and voting on the question of adjournment (and
shall if so directed by the meeting), adjourn the meeting from time to time and
from place to place, but no business shall be transacted at any adjourned
meeting except business which might lawfully have been transacted at the meeting
as originally called.


31.     Voting Power

                Subject to the provisions of Articles 3(b) and 32(a) and subject
to any other provision conferring special rights as to voting, or restricting
the right to vote, every member shall have one vote for each share held by him
of record, on every resolution, without regard to whether the vote thereon is
conducted by a show of hands, by written ballot or by any other means.


32.     Voting Rights

                (a) No member shall be entitled to vote at any General Meeting
(or be counted as a part of the quorum) unless all calls then payable by him in
respect of his shares in the Company have been paid, but this Article 32(a)
shall not apply to separate General Meetings of the holders of a particular
class of shares pursuant to Article 5(b).

                (b) A company or other corporate body being a member of the
Company may duly authorize any person to be its representative at any meeting of
the Company or to execute or deliver a proxy on its behalf. Any person so
authorized shall be entitled to exercise on behalf of such member all the power
which the latter could have exercised if it were an individual shareholder. Upon
the request of the Chairman of the meeting, written evidence of such
authorization (in form acceptable to the Chairman) shall be delivered to him.

                (c) Any member entitled to vote may vote either in person or by
proxy (who need not be a member of the Company) or, if the member is a company
or other corporate body, by a representative authorized pursuant to Article
32(b).

                (d) If two or more persons are registered as joint holders of
any shares, the vote of the senior who tenders a vote, in person or by proxy,
shall be accepted to the exclusion of the vote(s) of the other joint holder(s).
For the purpose of this Article 32(d), seniority shall be determined by the
order of registration of the joint holders in the Register of Members.



                                     PROXIES

<PAGE>   19

33.     Instrument of Appointment

                (a) An instrument appointing a proxy shall be in writing and
shall be substantially in the following form:


        "I_______________________ of ______________________________________
           (Name of Shareholder)           (Address of Shareholder)

        being a member of  BackWeb Technologies Ltd. hereby appoint
        _______________________ of _____________________________
           (Name of Proxy)               (Address of Proxy)
        as my Proxy to vote for me and on my behalf at the General Meeting of
        the Company to be held on the _________ day of ___________, ________ and
        at any adjournment(s) thereof.


        Signed this _____________ day of _______________, ____________.


                                            _____________________________
                                            (Signature of Appointor)"


or in any usual or common form or in such other form as may be approved by the
Board of Directors. Such proxy shall be duly signed by the appointor or such
person's duly authorized attorney or, if such appointor is a company or other
corporate body, under its common seal or stamp or the hand of its duly
authorized agent(s) or attorney(s).

                (b) The instrument appointing a proxy (and the power of attorney
or other authority, if any, under which such instrument has been signed) shall
either be delivered to the Company (at its registered office, at its principal
place of business, at the offices of its registrar or transfer agent, or at such
place as the Board of Directors may specify) not less than 24 hours before the
time fixed for the meeting at which the person named in the instrument proposes
to vote, or presented to the Chairman at such meeting.


34.     Effect of Death of Appointor or Transfer of Share and/or Revocation of
        Appointment

                (a) A vote cast in accordance with an instrument appointing a
proxy shall be valid notwithstanding the prior death or bankruptcy of the
appointing member (or of his attorney-in-fact, if any, who signed such
instrument), or the transfer of the share in



                                       19
<PAGE>   20

respect of which the vote is cast, unless written notice of such matters shall
have been received by the Company or by the Chairman of such meeting prior to
such vote being cast.

                (b) An instrument appointing a proxy shall be deemed revoked (i)
upon receipt by the Company or the Chairman, subsequent to receipt by the
Company of such instrument, of written notice signed by the person signing such
instrument or by the member appointing such proxy cancelling the appointment
thereunder (or the authority pursuant to which such instrument was signed) or of
an instrument appointing a different proxy (and such other documents, if any,
required under Article 33(b) for such new appointment), provided such notice of
cancellation or instrument appointing a different proxy were so received at the
place and within the time for delivery of the instrument revoked thereby as
referred to in Article 33(b) hereof, or (ii) if the appointing member is present
in person at the meeting for which such instrument of proxy was delivered, upon
receipt by the Chairman of such meeting of written notice from such member of
the revocation of such appointment, or if and when such member votes at such
meeting. A vote cast in accordance with an instrument appointing a proxy shall
be valid notwithstanding the revocation or purported cancellation of the
appointment, or the presence in person or vote of the appointing member at a
meeting for which it was rendered, unless such instrument of appointment was
deemed revoked in accordance with the foregoing provisions of this Article 34(b)
at or prior to the time such vote was cast.



                               BOARD OF DIRECTORS


35.     Powers of Board of Directors

                (a) In General

                The management of the business of the Company shall be vested in
the Board of Directors, which may exercise all such powers and do all such acts
and things as the Company is authorized to exercise and do, and are not hereby
or by law required to be exercised or done by the Company by action of its
members at a General Meeting. The authority conferred on the Board of Directors
by this Article 35 shall be subject to the provisions of the Companies
Ordinance, these Articles and any regulation or resolution consistent with these
Articles adopted from time to time by the Company by action of its members at a
General Meeting; provided, however, that no such regulation or resolution shall
invalidate any prior act done by or pursuant to a decision of the Board of
Directors which would have been valid if such regulation or resolution had not
been adopted.

                (b) Borrowing Power



                                       20
<PAGE>   21

                The Board of Directors may from time to time, at its discretion,
cause the Company to borrow or secure the payment of any sum or sums of money
for the purposes of the Company, and may secure or provide for the repayment of
such sum or sums in such manner, at such times and upon such terms and
conditions as it deems fit, and, in particular, by the issuance of bonds,
perpetual or redeemable debentures, debenture stock, or any mortgages, charges
or other securities on the undertaking or the whole or any part of the property
of the Company, both present and future, including its uncalled or called but
unpaid capital for the time being.

                (c) Reserves

                The Board of Directors may, from time to time, set aside any
amount(s) out of the profits of the Company as a reserve or reserves for any
purpose(s) which the Board of Directors, in its absolute discretion, shall deem
fit, and may invest any sum so set aside in any manner and from time to time
deal with and vary such investments and dispose of all or any part thereof, and
employ any such reserve or any part thereof in the business of the Company
without being bound to keep the same separate from other assets of the Company,
and may subdivide or redesignate any reserve or cancel the same or apply the
funds therein for another purpose, all as the Board of Directors may from time
to time think fit.


36.     Exercise of  Powers of Board of Directors

                (a) A meeting of the Board of Directors at which a quorum is
present shall be competent to exercise all the authorities, powers and
discretion vested in or exercisable by the Board of Directors.

                (b) A resolution proposed at any meeting of the Board of
Directors shall be deemed adopted if approved by a majority of the Directors
present when such resolution is put to a vote and voting thereon.

                (c) A resolution in writing signed by all the members of the
Board of Directors then in office and lawfully entitled to vote thereon or to
which all such Directors have given their written consent (by letter, telegram,
telex, facsimile, electronic mail or otherwise) shall be deemed to have been
unanimously adopted by a meeting of the Board of Directors duly convened and
held.


37.     Delegation of Powers

                (a) The Board of Directors may, subject to the provisions of the
Companies Ordinance, delegate any or all of its powers to committees, each
consisting of one or more persons (who are Directors), and it may from time to
time revoke such delegation or alter the composition of any such committee. Any
Committee so formed



                                       21
<PAGE>   22

(in these Articles referred to as a "Committee of the Board of Directors"),
shall, in the exercise of the powers so delegated, conform to any regulations
imposed on it by the Board of Directors. The meetings and proceedings of any
such Committee of the Board of Directors shall, mutatis mutandis, be governed by
the provisions contained in these Articles for regulating the meetings of the
Board of Directors, so far as not superseded by any regulations adopted by the
Board of Directors under this Article. Unless otherwise expressly provided by
the Board of Directors in delegating powers to a Committee of the Board of
Directors, such Committee shall not be empowered to further delegate such
powers.

                (b) Without derogating from the provisions of Article 50, the
Board of Directors may from time to time appoint a Secretary to the Company, as
well as officers, agents, employees and independent contractors, as the Board of
Directors deems fit, and may terminate the service of any such person. The Board
of Directors may, subject to the provisions of the Companies Ordinance,
determine the powers and duties, as well as the salaries and emoluments, of all
such persons, and may require security in such cases and in such amounts as it
deems fit.

                (c) The Board of Directors may from time to time, by power of
attorney or otherwise, appoint any person, company, firm or body of persons to
be the attorney or attorneys of the Company at law or in fact for such purpose
(s) and with such powers, authorities and discretion, and for such period and
subject to such conditions, as it deems fit, and any such power of attorney or
other appointment may contain such provisions for the protection and convenience
of persons dealing with any such attorney as the Board of Directors deems fit,
and may also authorize any such attorney to delegate all or any of the powers,
authorities and discretions vested in him.

38.     Number of Directors

                The Board of Directors shall consist of five (5) directors, or
such other number which is no less than four (4) and no more than seven (7), as
may be determined from time to time by an ordinary resolutions of the
shareholders; provided, that the number of directors may be increased from time
to time by resolution adopted by the affirmative vote of a majority of the
Continuing Directors (as defined below). The directors shall be divided into
three classes, designated Class I, Class II and Class III. Each class shall
consist, as nearly as may be possible, of one-third of the total number of
directors constituting the entire Board of Directors.


39.     Election and Removal of Directors

                (a) Subject to the provisions of Article 42, following the
closing of the Company's initial public offering, the Directors shall be divided
into three classes designated as Class I, Class II and Class III, respectively.
Directors shall be assigned to each class in accordance with a resolution or
resolutions adopted by the Board of



                                       22
<PAGE>   23

Directors. At the first annual meeting of shareholders following the closing of
the Company's initial public offering, the term of office of Class I directors
shall expire and Class I directors shall be elected for a full term of three
years. At the second annual meeting of shareholders following the closing of the
Company's initial public offering, the term of office of Class II directors
shall expire and Class II directors shall be elected for a full term of three
years. At the third annual meeting of shareholders following the closing of the
Company's initial public offering, the term of office of Class III directors
shall expire and Class III directors shall be elected for a full term of three
years. At each succeeding annual meeting of shareholders, Directors shall be
elected for a full term of three years to succeed the Directors of the class
whose terms expire at such annual meeting, subject to the provisions of Article
42. A director shall hold office until the annual meeting for the year in which
his or her term expires and until his or her successor shall be elected and
qualified. If the number of directors is changed, any increase or decrease shall
be apportioned among the classes so as to maintain the number of directors in
each class as nearly equal as possible. The holders of a majority of the voting
power represented at a General Meeting in person or by proxy and voting thereon
at such Meeting shall be entitled to remove any Director(s) from office.

                (b) Notwithstanding the foregoing nor and the provisions of
Article 41, whenever the holders of any one or more classes or series of shares
issued by the Corporation Company throughout the Articles shall have the right,
voting separately by class or series, to elect directors at an annual or special
meeting of shareholders, the election, term of office, filling of vacancies and
other features of such directorships shall be governed by the terms so provided
under the Articles of Association applicable at that time thereto such class or
series, and such directors so elected shall not be divided into classes pursuant
to this Article, and the number of such directors shall not be counted in
determining the maximum number of directors permitted under the foregoing
provision of this Article, in each case unless expressly provided by such terms.


40.     Qualification of Directors

                No person shall be disqualified to serve as a Director by reason
of his not holding shares in the Company or by reason of his having served as a
Director in the past.


41.     Continuing Directors in the Event of Vacancies

                Any additional director of any class elected to fill a vacancy
resulting from an increase in such class shall hold office for a term that shall
coincide with the remaining term of the class, but in no case will a decrease in
the number of directors shorten the term of any incumbent director. Any vacancy
on the Board of Directors for any reason, and any directorships resulting from
any increase in the number of directors of the Board of Directors, may be filled
by a decision of the majority of the Board of Directors then in office, even
where less than a quorum, and any directors so chosen shall hold office until



                                       23
<PAGE>   24

the next election of the class for which such directors shall have been chosen
and until their successors shall be elected and qualified.


42.     Vacation of Office

                (a) The office of a Director shall be vacated, ipso facto, upon
his death, or if he be found lunatic or become of unsound mind, or if he becomes
bankrupt, or if the Director is a company upon its winding-up.

                (b) The office of a Director shall be vacated by his written
resignation. Such resignation shall become effective on the date fixed therein,
or upon the delivery thereof to the Company, whichever is later.


43.     Remuneration of Directors

                A Director shall be paid remuneration by the Company for his
services as Director to the extent such remuneration shall have been approved by
a General Meeting of the Company and in accordance with the Companies Ordinance.


44.     Conflict of Interests

                Subject to the provisions of the Companies Ordinance, no
Director shall be disqualified by virtue of his office from holding any office
or place of profit under the Company or under any company in which the Company
shall be a shareholder or otherwise interested, or from contracting with the
Company as vendor, purchaser or otherwise, nor shall any such contract, or any
contract or arrangement entered into by or on behalf of the Company in which any
Director shall be in any way interested, be avoided, nor, other than as required
under the Companies Ordinance, shall any Director be liable to account to the
Company for any profit arising from any such office or place of profit or
realized by any such contract or arrangement by reason only of such Director's
holding that office or of the fiduciary relations thereby established, but the
nature of his interest, as well as any material fact or document, must be
disclosed by him at the meeting of the Board of Directors at which the contract
or arrangement is first considered, if his interest then exists, or, in any
other case, no later than at the first meeting of the Board of Directors after
the acquisition of his interest.


45.     Alternate Directors

                (a) A Director may, by written notice to the Company given in
the manner set forth in Article 45(b) below, appoint any individual (whether or
not such person is


                                       24
<PAGE>   25

then a member of the Board of Directors) as an alternate for himself (in these
Articles referred to as "Alternate Director"), remove such Alternate Director
and appoint another Alternate Director in place of any Alternate Director
appointed by him whose office has been vacated for any reason whatsoever. Unless
the appointing Director, by the instrument appointing an Alternative Director or
by written notice to the Company, limits such appointment to a specified period
of time or restricts it to a specified meeting or action of the Board of
Directors, or otherwise restricts its scope, the appointment shall be for all
purposes, and for a period of time concurrent with the term of the appointing
Director.

                (b) Any notice to the Company pursuant to Article 45(a) shall be
given in person to, or by sending the same by mail to the attention of, the
General Manager of the Company at the principal office of the Company, to such
other persons or place as the Board of Directors shall have determined for such
purpose, and shall become effective on the date fixed therein or upon the
receipt thereof by the Company, whichever is later.

                (c) An Alternate Director shall have all the rights and
obligations of the Director who appointed him; provided, however, that (i) he
may not in turn appoint an alternate for himself (unless the instrument
appointing him otherwise expressly provides), (ii) an Alternate Director shall
have no standing at any meeting of the Board of Directors or any committee
thereof while the Director who appointed him is present, and (iii) the Alternate
Director is not entitled to remuneration.

                (d) Any individual, whether or not he be a member of the Board
of Directors, may act as an Alternate Director. One person may act as Alternate
Director for several Directors, and in such event he shall have a number of
votes (and shall be treated as the number of persons for purposes of
establishing a quorum) equal to the number of Directors for whom he acts as
Alternative Director. If an Alternate Director is also a Director in his own
right, his rights as an Alternate Director shall be in addition to his rights as
a Director.

                (e) An Alternate Director shall alone be responsible for his own
acts and defaults, and he shall not be deemed the agent of the Director(s) who
appointed him.

                (f) The office of an Alternate Director shall be vacated under
the circumstances, mutatis mutandis, set forth in Article 42, and such office
shall ipso facto be vacated if the Director who appointed such Alternate
Director ceases to be a Director.



                      PROCEEDINGS OF THE BOARD OF DIRECTORS


46.     Meetings



                                       25
<PAGE>   26

                (a) The Board of Directors may meet and adjourn its meeting and
otherwise regulate such meetings and proceedings as the Directors think fit.

                (b) Any Director may at any time, and the Secretary, upon the
request of such Director, shall, convene a meeting of the Board of Directors,
but not less than seven (7) days' notice shall be given of any meeting so
convened. Notice of any such meeting may be given orally, by telephone, in
writing or by mail, electronic mail, telex, cablegram or facsimile.
Notwithstanding anything to the contrary herein, failure to deliver notice to a
Director of any such meeting in the manner required hereby may be waived by such
Director, and a meeting shall be deemed to have been duly convened
notwithstanding such defective notice if such failure or defect is waived prior
to action being taken at such meeting by all Directors entitled to participate
at such meeting to whom notice was not duly given as aforesaid.


47.     Quorum

                Until otherwise unanimously decided by the Board of Directors, a
quorum at a meeting of the Board of Directors shall be constituted by the
presence in person or by telephone conference of a majority of the Directors
then in office who are lawfully entitled to participate in the meeting. No
business shall be transacted at a meeting of the Board of Directors unless the
requisite quorum is present (in person or by telephone conference) when the
meeting proceeds to business.


48.     Chairman of the Board of Directors

                The Board of Directors may from time to time elect one of its
members to be the Chairman of the Board of Directors and another of its members
to be the Co-Chairman, remove such Chairman and Co-Chairman from office, and
appoint others in their place. The Chairman of the Board of Directors shall
preside at every meeting of the Board of Directors, but if there is no such
Chairman, or if at any meeting he is not present within fifteen (15) minutes of
the time fixed for the meeting or if he is unwilling to take the chair, the
Co-Chairman shall preside. If both the Chairman and the Co-Chairman are not
present or are unwilling to take the chair, the Directors present shall choose
one of their number to be the chairman of such meeting.


49.     Validity of Acts Despite Defects

                All acts done bona fide at any meeting of the Board of
Directors, or of a Committee of the Board of Directors, or by any person (s)
acting as Director (s), shall, notwithstanding that it may afterwards be
discovered that there was some defect in the appointment of the participants in
such meetings or any of them or any person(s) acting as



                                       26
<PAGE>   27

aforesaid, or that they or any of them were disqualified, be as valid as if
there were no such defect of disqualification.



                      CHIEF EXECUTIVE OFFICER AND PRESIDENT


50.     Chief Executive Officer and President

                The Board of Directors may from time to time appoint one or more
persons, whether or not Directors, as Chief Executive Officer or Officers,
General Manager or Managers, or President of the Company and may confer upon
such person(s), and from time to time modify or revoke, such title(s) and such
duties and authorities of the Board of Directors as the Board of Directors may
deem fit, subject to such limitations and restrictions as the Board of Directors
may from time to time prescribe. Unless otherwise determined by the Board of
Directors, the Chief Executive Officer shall have authority with respect to the
management of the Company in the ordinary course of business. Such appointment
(s) may be either for a fixed term or without any limitation of time, and the
Board of Directors may from time to time (subject to the provisions of the
Companies Ordinance and of any contract between any such person and the Company)
fix his or their salaries and emoluments, remove or dismiss him or them from
office and appoint another or others in his or their place or places.

51.     Minutes

                (a) Minutes of each General Meeting and of each meeting of the
Board of Directors shall be recorded and duly entered in books provided for that
purpose, and shall be held by the Company at its registered office or such other
place as shall have been determined by the Board of Directors. Such minutes
shall, in all events, set forth the names of the persons present at the meeting
and all resolutions adopted thereat.

chairman of the meeting or by the chairman of the next succeeding meeting, shall

                                    DIVIDENDS


52.     Declaration of  Dividends

                The Board of Directors may from time to time declare, and cause
the Company to pay, such interim dividend as may appear to the Board of
Directors to be justified by the profits of the Company. The final dividend in
respect of any fiscal period shall be proposed by the Board of Directors and
shall be payable only after the same has been approved by Ordinary Resolution of
the Company, but no such resolution shall provide for the payment of an amount
exceeding that proposed by the Board of Directors for the payment of such final
dividend, and no such resolution or any failure to approve a final dividend
shall affect any interim dividend previously declared and paid. The Board of
Directors shall determine the time for payment of such dividends, both interim
and final, and the record date for determining the shareholders entitled
thereto.


53.     Funds Available for Payment of Dividends

                No dividend shall be paid otherwise than out of the profits of
the Company.


54.     Amount Payable by Way of  Dividends

                (a) Subject to the rights of the holders of shares as to
dividends, any dividend paid by the Company shall be allocated among the members
entitled thereto in proportion to the sums paid up or credited as paid up on
account of the nominal value of their respective holdings of the shares in
respect of which such dividend is being paid, without taking into account the
premium paid up for the shares. The amount paid up on account of a share which
has not yet been called for payment or fallen due for payment and upon which the
Company pays interest to the shareholder shall not be deemed, for the purposes
of this Article, to be a sum paid on account of the share.

                (b) Whenever the rights attached to any shares or the terms of
issue of the share do not provide otherwise, shares which are fully paid up or
which are credited as fully or partly paid within any period in respect of which
dividends are paid shall entitle the holders thereof to a dividend in proportion
to the amount paid up or credited as paid up in respect of the nominal value of
such shares and to the date of payment thereof (pro rata temporis).


55.     Interest

                No dividend shall carry interest as against the Company.



                                       28
<PAGE>   29

56.     Payment in Specie

                Upon the recommendation of the Board of Directors approved by
Ordinary Resolution of the Company, the Company (i) may cause any moneys,
investments, or other assets forming part of the undivided profits of the
Company, standing to the credit of a reserve fund, to the credit of a reserve
fund for the redemption of capital or in the hands of the Company and available
for dividends, or representing premiums received on the issuance of shares and
standing to the credit of the share premium account, to be capitalized and
distributed among such of the shareholders as would be entitled to receive the
same if distributed by way of dividend and in the same proportion, on the
footing that they become entitled thereto as capital, or may cause any part of
such capitalized fund to be applied on behalf of such shareholders in paying up
in full, either at par or at such premium as the resolution may provide, any
unissued shares or debentures or debenture stock of the Company which shall be
distributed accordingly, in payment, in full or in part, of the uncalled
liability on any issued shares or debentures or debenture stock; and (ii) may
cause such distribution or payment to be accepted by such shareholders in full
satisfaction of their interest in the said capitalized sum.


57.     Implementation of Powers under Article 56

                For the purpose of giving full effect to any resolution under
Article 56, and without derogating from the provisions of Article 6(b) hereof,
the Board of Directors may settle any difficulty which may arise in regard to
the distribution as it thinks expedient, and, in particular, may issued
fractional certificates, and may fix the value for distribution of any specific
assets, and may determine that cash payments shall be made to any member upon
the footing of the value so fixed, or that fractions of less value than the
nominal value of one share may be disregarded in order to adjust the right of
all parties, and may vest any such cash, shares, debentures, debenture stock or
specific assets in trustees upon such trusts for the persons entitled to the
dividend or capitalized fund as may seem expedient to the Board of Directors.
Where requisite, a proper contract shall be filed in accordance with Section 130
of the Companies Ordinance, and the Board of Directors may appoint any person to
sign such contract on behalf of the persons entitled to the dividend or
capitalized fund.


58.     Dividends on Unpaid Shares

                Without derogating from Article 54 hereof, the Board of
Directors may give an instruction which shall prevent the distribution of a
dividend to the holders of shares whose full nominal amount has not been paid
up.



                                       29
<PAGE>   30

59.     Retention of Dividends

                (a) The Board of Directors may retain any dividend or other
moneys payable or property distributable in respect of a share on which the
Company has a lien, and may apply the same in or toward satisfaction of the
debts, liabilities or obligations in respect of which the lien exists.

                (b) The Board of Directors may retain any dividend or other
moneys payable or property distributable in respect of a share in respect of
which any person is, under Articles 20 or 21, entitled to become a member, or
which any person is, under said Articles, entitled to transfer, until such
person shall become a member in respect of such share or shall transfer the
same.


60.     Unclaimed Dividends

                All unclaimed dividends or other moneys payable in respect of a
share may be invested or otherwise made use of by the Board of Directors for the
benefit of the Company until claimed. The payment by the Directors of any
unclaimed dividend or such other moneys into a separate account shall not
constitute the Company a trustee in respect thereof. The principal (and only the
principal) of an unclaimed dividend or such other moneys shall be, if claimed,
paid to a person entitled thereto.


61.     Mechanics of Payment

                Any dividend or other moneys payable in cash in respect of a
share may be paid by check or warrant sent through the post to, or left at, the
registered address of the person entitled thereto or by transfer to a bank
account specified by such person (or, if two or more persons are registered as
joint holders of such share or are entitled jointly thereto in consequence of
the death or bankruptcy of the holder or otherwise, to the joint holder whose
name is registered first in the Register of Members of his bank account or the
person who the Company may then recognize as the owner thereof or entitled
thereto under Article 20 or 21 hereof, as applicable, or such person's bank
account), or to such person and at such other address as the person entitled
thereto may be writing direct. Every such check or warrant shall be made payable
to the order of the person to whom it is sent, or to such person as the person
entitled thereto as aforesaid may direct, and payment of the check or warrant by
the banker upon whom it is drawn shall be a good discharge to the Company.


62.     Receipt from a Joint Holder

                If two or more persons are registered as joint holders of any
share, or are entitled jointly thereto in consequence of the death or bankruptcy
of the holder or



                                       30
<PAGE>   31

otherwise, any one of them may give effectual receipts for any dividend or other
moneys payable or property distributable in respect of such shares.


                                    ACCOUNTS


63.     Books of Account

                The Board of Directors shall cause accurate books of account to
be kept in accordance with the provisions of the Companies Ordinance and of any
other applicable law. Such books of account shall be kept at the Registered
Office of the Company, or at such other place or places as the Board of
Directors may think fit, and they shall always be open to inspection by all
Directors. No member, not being a Director, shall have any right to inspect any
account or book or other similar document of the Company, except as conferred by
law or authorized by the Board of Directors or by Ordinary Resolution of the
Company.


64.     Audit

                At least once in every fiscal year the accounts of the Company
shall be audited and the correctness of the profit and loss account and balance
sheet certified by one or more duly qualified auditors.


65.     Auditors

                The appointment, authorities, rights and duties of the
auditor(s) of the Company shall be regulated by applicable law; provided,
however, that in exercising its authority to fix the remuneration of the
auditor(s), the members in General Meeting may, by Ordinary Resolution, act (and
in the absence of any action in connection therewith shall be deemed to have so
acted) to authorize the Board of Directors to fix such remuneration subject to
such criteria or standards, if any, as may be provided in such Ordinary
Resolution, and if no such criteria or standards are so provided, such
remuneration shall be fixed in an amount commensurate with the volume and nature
of the services rendered by such auditor(s).

to 80, inclusive, of the Companies Ordinance and to all orders and regulations
issued thereunder, the Company may cause branch registers to be kept in any
place outside Israel as the Board of Directors may think fit, and, subject to
all applicable requirements of law, the Board of Directors may from time to time
adopt such rules and procedures as it may think fit in connection with the
keeping of such branch registers.

(five percent) of the issued and outstanding share capital of the Company, or
their relatives.

                (c) All of the following matters shall be brought before the

of the Board of Directors may be given only following the Audit Committee's
approval:

                        (i) proposed transactions to which the Company intends
to be a party in which an Officer Holder has a direct or indirect Personal
Interest;

                        (ii) actions which may otherwise be deemed to constitute
a breach of fiduciary duty or the duty of care, as defined in Section 96(27) of
the Companies Ordinance, of an Office Holder of the Company;

                        (iii) agreements with directors as to the terms of their

Directors have a Personal Interest in any of the matters detailed in Section

be subject to approval of the General Meeting.

                (g) Any Office Holder whose interest is brought before the Audit
Committee and the Board of Directors for approval shall not be present nor shall
he have a vote at any meeting at which his interest shall be discussed or voted
upon.


                             INDEMNITY AND INSURANCE


68.     Indemnity and Insurance

                Subject to the provisions of the Companies Ordinance, the
Company may (i) procure insurance for, or indemnify any Office Holder, to the
fullest extent permitted and not prohibited by Sections 96(41) and 96(42) of the
Companies Ordinance, or any successor provisions; provided, however, that the
procurement of any such insurance or provision of any such indemnification, as
the case may be, is approved by the Audit Committee of the Company and otherwise
as required by law; or (ii) procure insurance for or indemnify any person who is
not an Office Holder, including, without limitation, any employee, agent,

shall bind the Company insofar as such person(s) acted and signed within the
scope of his or their authority.

of Directors so provides, it shall also provide for the safe custody thereof.

Company upon any member either personally or by sending it by prepaid mail
(airmail if sent internationally) addressed to such member at his address as
described in the Register of Members or such other address as he may have
designated in writing for the receipt of notices and other documents. Any
written notice or other document may be served by any member upon the Company by
tendering the name in person to the Secretary or the General Manager of the
Company at the principal office of the Company or by sending it by prepaid
registered mail (airmail if posted outside Israel) to the Company at its
registered office. Any such notice or other document shall be deemed to have
been served forty-eight (48) hours after it has been posted (seven (7) business
days if sent internationally), or when actually received by the addressee if
sooner than forty-eight hours or seven days, as the case may be, after it has
been posted, or when actually tendered in person, to such member (or to the
Secretary) or the General Manager). Notice sent by cablegram, telex, facsimile
or electronic mail shall be deemed to have been served when actually received by
such member (or by the Company). If a notice is, in fact, received by the
addressee, it shall be deemed to have been duly served when received,
notwithstanding that it was defectively addressed or failed, in some other
respect, to comply with the provisions of this Article 71(a).

                      OF THESE SHARES AND RESTRICTING THEIR TRANSFER MAY BE
                      OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER
                      OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE
                      COMPANY AT THE PRINCIPAL EXECUTIVE OFFICES OF THE

        4.     NOTICE OF PROPOSED TRANSFERS. The holder of each certificate
representing Restricted Securities by acceptance thereof agrees to comply in all
respects with the provisions of this Section 4. Prior to any proposed sale,
assignment, transfer or pledge of any Restricted Securities (other than (a) a
transfer not involving a change in beneficial ownership (which shall be deemed
to include without limitation a transfer between and among affiliates), (b) in
transactions involving the distribution without consideration of Restricted
Securities by any of the Purchasers to any of its partners, or retired partners,

one or more affiliated partnerships managed by it, so long as each such
transferee agrees in writing to be bound by the terms of this Agreement or (c)
the exchange of any Exchangeable Shares for Ordinary Shares), unless there is in
effect a registration statement under the Securities Act covering the proposed
transfer, the holder thereof shall give written notice to the Company of such
holder's intention to effect such transfer, sale, assignment or pledge. Each
such notice shall describe the manner and circumstances of the proposed
transfer, sale, assignment or pledge in sufficient detail, and shall be
accompanied, at such holder's expense by either (a) an unqualified written
opinion of legal counsel addressed to the Company, to the effect that the
proposed transfer of the Restricted Securities may be effected without
registration under the Securities Act, or (b) a "no action" letter from the
Commission to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such
Restricted Securities shall be entitled to transfer such Restricted Securities
in accordance with the terms of the notice delivered by the holder to the
Company. Each certificate evidencing the Restricted Securities transferred as
above provided shall bear, except if such transfer is made pursuant to Rule 144,
the appropriate restrictive legend set forth in Section 3 above, except that
such certificate shall not bear such restrictive legend if in the opinion of
counsel for such holder and the Company such legend is not required in order to
establish compliance with any provision of the Securities Act.

to effect such registration, qualification or compliance (including, without
limitation, the execution of an undertaking to file post-effective amendments,
appropriate qualification under applicable blue sky or other state securities
laws and appropriate compliance with applicable regulations issued under the
Securities Act) as may be so requested and as would permit or facilitate the
sale and distribution of all or such portion of such Registrable Securities as
are specified in such request, together with all or such portion of the
Registrable Securities of any Holder or Holders joining in such request as are
specified in a written request given within fifteen (15) days after receipt of
such written notice from the Company, provided, however, that the Company shall
not be obligated to take any action to effect any such registration,
qualification or compliance pursuant to this Section 5:

                                    (1)    In any particular jurisdiction in
which the Company would be required to execute a general consent to service of
process in effecting such registration, qualification or compliance unless the
Company is already subject to service in such jurisdiction and except as may be
required by the Securities Act;

                                    (2)    Prior to the earlier of (a) five (5)
years following December 26, 1997, or (b) six months after the effective date of
the registration statement pertaining to the first underwritten firm commitment
public offering of securities of the Company for its own account (other than a
registration relating solely to a Commission Rule 145 transaction or a
registration relating solely to employee benefit plans);

                                    (3)    (i) In the case of a demand made by
Initiating Holders, if the Company has previously effected two (2) such
registrations of Preferred (and Ordinary Shares issued upon conversion thereof)
such registrations have been declared or ordered effective and the securities
offered pursuant to such registrations have been sold and (ii) in the case of a
demand made by the Exchangeable Share Initiating Holders, if the Company has
previously effected one (1) such registration of Exchangeable Shares (and
Ordinary Shares issued upon conversion thereof) and such registration has been
declared or ordered effective and the securities offered pursuant to such
registration has been sold.

                                    (4)    If at the time of the request to
register Registrable Securities the Company gives notice within thirty (30) days
of such request that it is engaged or has fixed plans to engage within thirty
(30) days of the time of the request in a firmly underwritten registered public
offering in which the Holders may include Registrable Securities pursuant to
Section 5, 6 or 7 hereof.

                                    (5)    Within 180 days after the effective
date of any other registration effected pursuant to this Section 5.1.

<PAGE>   9



               Subject to the foregoing clauses (1) through (5) and to Section
5.3, the Company shall file a registration statement covering the Registrable
Securities so requested to be registered as soon as practicable after receipt of
the request of the Initiating Holders or the Exchangeable Share Initiating
Holders, as the case may be.

               5.2    Underwriting.

                      (a)    If the Initiating Holders or the Exchangeable Share
Initiating Holders, as the case may be, intend to distribute the Registrable
Securities covered by their request by means of an underwriting, they shall so
advise the Company as a part of their request made pursuant to Section 5 and the
Company shall include such information in the written notice referred to in
Section 5.1. The right of any Holder to registration pursuant to Section 5 shall
be conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent requested (unless otherwise mutually agreed by a majority in interest of
the Initiating Holders or the Exchangeable Share Initiating Holders, as the case
may be, and such Holder) as provided herein.

                      (b)    The Company shall (together with all Holders
proposing to distribute their securities through such underwriting) enter into
an underwriting agreement in customary form with the Underwriter selected for
such underwriting by a majority in interest of the Initiating Holders or the
Exchangeable Share Initiating Holders, as the case may be. If any Holder
disapproves of the terms of the underwriting, such person may elect to withdraw
therefrom by written notice to the Company, the Underwriter and the Initiating
Holders or the Exchangeable Share Initiating Holders, as the case may be. The
Registrable Securities and/or other securities so withdrawn from such
underwriting shall also be withdrawn from such registration; provided, however,
that, if by the withdrawal of such Registrable Securities a greater number of
Registrable Securities held by other Holders may be included in such
registration (up to the maximum of any limitation imposed by the underwriters),
then the Company shall offer to all Holders who have included Registrable
Securities in the registration the right to include additional Registrable
Securities in proportion (as nearly as practicable) to the total amount of
Registrable Securities held by each such Holder.

                      (c)    Notwithstanding any other provision of this Section
5, if the Underwriter determines that marketing factors require a limitation on
the number of shares to be underwritten, the Underwriter may limit the number of
Registrable Securities to be included in the registration and underwriting;
provided, however, that the number of shares of Registrable Securities offered
by the Holders and other holders that may be included in the registration and
underwriting shall be allocated among the Holders and other holders in
proportion, as nearly as practicable, to the respective aggregate amounts of
Registrable Securities and other securities entitled to registration held by
such Holders and other holders at the time of filing the registration statement.
If the Underwriter has not so limited the number of Registrable Securities to be
underwritten, the Company may include securities for its own account or the
account of others in such registration if the Underwriter so agrees and if the
number of Registrable Securities which would otherwise have been included in
such registration and underwriting will not thereby be limited or the price
applicable to such included Registrable Securities will not thereby be reduced.

               5.3    Subordination of Certain Rights. To the extent that the
Exchangeable Share Holders shall be able to utilize the closing date of the
Amalgamation as the original purchase date with respect to the Ordinary Shares
that such Exchangeable Share Holders ultimately receive in respect of such
Exchangeable Shares, for purposes of the holding period required under Rule
144(d) of the Securities Act (other than an inability to use such closing date
as the original purchase date for the purposes of Rule 144(d) due to an action
taken by the holder thereof, such as a pledge of shares, which tolls the holding
period under Rule 144(d)) so that such Exchangeable Shares Holders shall be able
to sell their Registrable Securities without registration under the Securities
Act, then the right of the Exchangeable Share Holders to include their
Registrable Securities in any registration as to which they exercise
registration rights shall be subordinate to the other holders of registration
rights and, in this regard, in the event that the underwriters of an offering
determine that marketing restrictions require a limitation in the total number
of shares to be included in the offering on behalf of holders of registration
rights, then all other holders of registration rights shall be entitled to
include the full number of shares in such registration and offering desired by
them before inclusion of shares in such registration and offering on the part of
the Exchangeable Share Holders. This Section 5.3 shall also apply to any
registration effectuated under the terms of Article 6 of this Agreement.

               5.4    Delay of Registration. If the Company shall furnish to the
Initiating Holders or the Exchangeable Share Initiating Holders, as the case may
be, a certificate signed by the President of the Company stating that, in the
good faith judgment of the Board of Directors of the Company, it would be not in
the best interests of the Company and its stockholders for such registration
statement to be filed on or before the date filing would be required and it is
therefore appropriate to defer the filing of such registration statement, then
the Company may direct that such request for registration be delayed for a
period not in excess of one hundred and eighty (180) days, such right to delay a
request to be exercised by the Company no more than once in any twelve month
period.

        6.     COMPANY REGISTRATION.

               6.1    Notice of Registration. If at any time or from time to
time the Company shall determine to register any of its equity securities,
either for its own account or the account of a security holder or holders, other
than (a) a registration relating solely to employee benefit plans, or (b) a
registration relating solely to a Rule 145 transaction, the Company shall:

                             (i)    promptly give to each Holder written notice
thereof; and

                             (ii)   include in such registration (and any
related qualification under blue sky laws or other compliance), and in any
underwriting involved therein, all the Registrable Securities specified in a
written request or requests, made within fifteen (15) days after receipt of such
written notice from the Company, by any Holder.

               6.2    Underwriting. If the registration of which the Company
gives notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 6.1(i). In such event the right of any Holder to
registration pursuant to this Section 6 shall be conditioned upon such Holder's
participation in such



                                      -10-
<PAGE>   11



underwriting and the inclusion of Registrable Securities in the underwriting to
the extent provided herein. All Holders proposing to distribute their securities
through such underwriting shall (together with the Company and the other holders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the Underwriter selected for such
Underwriting by the Company. Notwithstanding any other provision of this Section
6, if the Underwriter determines that marketing factors require a limitation of
the number of shares to be underwritten, the underwriter may limit, on a pro
rata basis, the Registrable Securities to be included in such registration;
provided, however, that in no public offering shall other holders of "piggyback"
registration rights participate in such offering unless the Holders (including
the Exchangeable Share Holders, unless such Exchangeable Share Holders shall be
entitled to use the closing date of the Amalgamation as the original purchase
date for their Ordinary Shares for Rule 144(d) purposes in the manner
contemplated by Section 5.3) have participated to the full extent requested. The
Company shall so advise all Holders and other holders distributing their
securities through such underwriting and the number of shares of Registrable
Securities and other securities that may be included in the registration and
underwriting shall be allocated among all Holders and other holders in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities and other securities entitled to registration held by such Holders
and other holders at the time of filing the registration statement. To
facilitate the allocation of shares in accordance with the above provisions, the
Company may round the number of shares allocated to any Holder or holder to the
nearest one hundred (100) shares. If any Holder or holder disapproves of the
terms of any such underwriting, he may elect to withdraw therefrom by written
notice to the Company and the managing underwriter.

               6.3    Right to Terminate Registration. The Company shall have
the right to terminate or withdraw any registration initiated by it under this
Section 6 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration.

        7.     REGISTRATION ON FORM F-3.

               (a)    If any Holder or Holders request that the Company file a
registration statement on Form F-3 (or any successor form to Form F-3) for a
public offering of shares of the Registrable Securities the reasonably
anticipated aggregate price to the public of which, net of underwriting
discounts and commissions, would exceed $1,000,000 and the Company is a
registrant entitled to use Form F-3 to register the Registrable Securities for
such an offering, the Company shall use its best efforts to cause such
Registrable Securities to be registered for the offering on such form and to
cause such Registrable Securities to be qualified in such jurisdictions as the
Holder or Holders may reasonably request; provided, however, that the Company
shall not be obligated to effect more than four (4) registrations under this
Section 7.

               (b)    Notwithstanding the foregoing, the Company shall not be
obligated to take any action pursuant to this Section 7: (i) more than once in
any twelve (12) month period; (ii) in any particular jurisdiction in which the
Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act; (iii) if the Company, within ten (10) days of the receipt of
the request of a Holder or Holders pursuant to this Section 7, gives notice of
its bona fide intention to effect the filing of a registration statement with
the



                                      -11-
<PAGE>   12
Commission within sixty (60) days of receipt of such request (other than with
respect to a registration statement relating to a Rule 145 transaction, an
offering solely to employees or any other registration which is not appropriate
for the registration of Registrable Securities) in which such Holders can
exercise their rights pursuant to Section 6 hereof; or (iv) during the period
starting with the date sixty (60) days prior to the Company's estimated date of
filing of, and ending on the date three (3) months immediately following, the
effective date of any registration statement pertaining to securities of the
Company (other than a registration of securities in a Rule 145 transaction or
with respect to an employee benefit plan), provided that the Company is actively
employing in good faith all reasonable efforts to cause such registration
statement to become effective.

               (c)    Registrations effected pursuant to this Section 7 shall
not be counted as demands for registration or registrations effected pursuant to
Section 5 or Section 6, respectively.

        8.     LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and after the
date of this Agreement, the Company shall not, without the consent of Holders of
in excess of 50% of the Registrable Securities, enter into any agreement
granting any holder or prospective holder of any securities of the Company
registration rights with respect to such securities, unless (i) such new
registration rights, including standoff obligations, are on a basis no more
favorable to the holders thereof than those rights of the Holders hereunder
(other than Exchangeable Share Holders, to the extent of subordination under
Section 5.3); or (ii) such new registration rights, including standoff
obligations, are subordinate to the registration rights granted Holders
hereunder.

        9.     EXPENSES OF REGISTRATION. All Registration Expenses incurred in
connection with all registrations pursuant to Section 5, Section 6 and Section 7
shall be borne by the Company. All Selling Expenses relating to securities
registered on behalf of the Holders shall be borne by the Holders of such
securities pro rata on the basis of the number of shares so registered.
Notwithstanding anything in this Section 9 to the contrary, if the Company
and/or others include securities for their own account pursuant to Section 5.2,
then the Company and such others shall bear their pro rata share of the
Registration Expenses and Selling Expenses.

        10.    REGISTRATION PROCEDURES. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Agreement,
the Company shall keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof. At its expense the Company shall:

               (a)    Prepare and file with the Commission a registration
statement, and all requisite supplements and amendments thereto, with respect to
such securities and use its best efforts to cause such registration statement,
as amended, to become and remain effective for at least one hundred twenty (120)
days or until the distribution described in the Registration Statement has been
completed;

               (b)    Furnish to the Holders participating in such registration
and to the underwriters of the securities being registered such reasonable
number of copies of the registration statement, and all supplements and
amendments thereto, preliminary prospectus, final prospectus and such other
documents as such Holders may reasonably request in order to facilitate the
public offering of such securities and



                                      -12-
<PAGE>   13



such other information necessary to allow the Holders participating in such
registration to remain reasonably informed about the public offering;

               (c)    Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
blue sky laws of such jurisdictions as shall be reasonably requested by the
Holders participating in such registration; provided, however, that the Company
shall not be required in connection therewith or as a condition thereto to
qualify to do business or to file a general consent to service for process in
any such states or jurisdictions;

               (d)    In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the underwriter of such offering;

               (e)    Notify each Holder of Registrable Securities covered by
such registration statement, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing; and

               (f)    Furnish, at the request of any Holder requesting
registration of Registrable Securities pursuant to Section 5, Section 6 or
Section 7 above, on the date that such Registrable Securities are delivered to
the underwriters for sale in connection with a registration statement pursuant
to Section 5, Section 6 or Section 7 above, if such securities are being sold
through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated such date, of counsel
representing the Company for the purposes of registration, if any, and addressed
to the Holders requesting registration of Registrable Securities, in form and
substance as is customarily given by counsel representing the Company to the
underwriters in an underwritten public offering, and (ii) a letter, dated such
date, from the independent certified public accountants of the Company, in form
and substance as is customarily given by independent public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities.

        11.    INDEMNIFICATION.

               (a)    The Company will indemnify each Holder, each of its
officers and directors and partners, and each person controlling such Holder
within the meaning of Section 15 of the Securities Act, with respect to which
registration, qualification or compliance has been effected pursuant to this
Agreement, and each underwriter, if any, and each person who controls any
underwriter within the meaning of Section 15 of the Securities Act, or the
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), against all
expenses, claims, losses, damages or liabilities (joint or several) (or actions
in respect thereof), to which they become subject under the Securities Act or
the Exchange Act, including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any



                                      -13-
<PAGE>   14



registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereto, incident to any such registration,
qualification or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances in which they were
made, not misleading, or any violation by the Company of the Securities Act or
the Exchange Act or any rule or regulation promulgated thereunder applicable to
the Company in connection with any such registration, qualification or
compliance, and the Company will pay to each such Holder, each of its officers
and directors, and each person controlling such Holder, each such underwriter
and each person who controls any such underwriter, any legal and any other
expenses reasonably incurred as such expenses are incurred in connection with
investigating, preparing or defending any such claim, loss, damage, liability or
action, provided that the Company will not be liable in any such case to the
extent that any such claim, loss, damage, liability or expense arises out of or
is based on any untrue statement or omission or alleged untrue statement or
omission, made in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder,
controlling person or underwriter and stated to be specifically for use therein;
provided, however, that the indemnity agreement contained in this Section 11(a)
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Company, which consent shall not be unreasonably withheld.

               (b)    Each Holder will, if Registrable Securities held by such
Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors and officers, each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
the Company or such underwriter within the meaning of Section 15 of the
Securities Act or the Exchange Act, and each other such Holder, each of its
officers and directors and each person controlling such Holder within the
meaning of Section 15 of the Securities Act or the Exchange Act, against all
claims, losses, damages and liabilities (or actions in respect thereof) to which
any of the foregoing persons may become subject under the Securities Act or the
Exchange Act, arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement,
prospectus, offering circular or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Company, such Holders, such directors, officers, persons, underwriters or
control persons for any legal or any other expenses reasonably incurred as such
expenses are incurred in connection with investigating or defending any such
claim, loss, damage, liability or action, in each case to the extent, but only
to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
prospectus, offering circular or other document in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Holder and stated to be specifically for use therein;
provided, however, that the indemnity agreement contained in this Section 11(b)
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Holder, which consent shall not be unreasonably withheld. Notwithstanding the
foregoing, the liability of each Holder under this Section 11(b) shall be
limited to an amount equal to the aggregate proceeds received by such Holder
from the sale of Registrable Securities hereunder, unless such liability arises
out of or is based on willful conduct by such Holder.



                                      -14-
<PAGE>   15



               (c)    Each party entitled to indemnification under this Section
11 (the "INDEMNIFIED PARTY") shall give notice to the party required to provide
indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations under this Agreement unless the failure to give such notice is
materially prejudicial to an Indemnifying Party's ability to defend such action
and provided further, that the Indemnifying Party shall not assume the defense
for matters as to which there is a conflict of interest or separate and
different defenses. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

        12.    INFORMATION BY HOLDER. The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders, the Registrable Securities held by
them and the distribution proposed by such Holder or Holders as the Company may
reasonably request in writing and as shall be required in connection with any
registration, qualification or compliance referred to in this Agreement.

        13.    RULE 144 REPORTING. With a view to making available the benefits
of certain rules and regulations of the Commission which may at any time permit
the sale of the Restricted Securities to the public without registration, after
such time as a public market exists for the Ordinary Shares of the Company, the
Company agrees to use its best efforts to:

               (a)    Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the effective date that the Company becomes subject to the reporting
requirements of the Securities Act or the Exchange Act.

               (b)    Use its best efforts to file with the Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements);

               (c)    Take such action, including the voluntary registration of
its Ordinary Shares under Section 12 of the Exchange Act, as is necessary to
enable the Holders to utilize Form F-3 for the sale of their Registrable
Securities, such registration under Section 12 to be taken as soon as
practicable after the six-month period following the date on which the first
registration statement filed by the Company for the offering of its securities
to the general public is declared effective.

               (d)    So long as a Purchaser owns any Restricted Securities to
furnish to the Purchaser forthwith upon request a written statement by the
Company as to its compliance with the reporting



                                      -15-
<PAGE>   16



requirements of said Rule 144 (at any time after ninety (90) days after the
effective date of the first registration statement filed by the Company for an
offering of its securities to the general public), and of the Securities Act and
the Exchange Act (at any time after it has become subject to such reporting
requirements), a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents of the Company and other
information in the possession of or reasonably obtainable by the Company as a
Purchaser may reasonably request in availing itself of any rule or regulation of
the Commission allowing a Purchaser to sell any such securities without
registration.

        14.    TRANSFER OF REGISTRATION RIGHTS. The rights to cause the Company
to register securities granted to a Holder under Sections 5, 6 and 7 may be
assigned (i) to partners and constituent members, former partners and former
constituent members and Affiliates of that Holder, and (ii) to other persons
provided that (a) such transfer may otherwise be effected in accordance with
applicable securities laws, (b) such assignee or transferee acquires at least
800,000 shares of Registrable Securities (as may be appropriately adjusted upon
any stock split, stock dividend, recapitalization, merger, consolidation or
similar event) and (c) such assignee or transferee agrees to be bound by the
terms of this Agreement and assumes all of the obligations of the transferring
Holder hereunder.

        15.    STANDOFF AGREEMENT. Each Holder hereby agrees that, during the
period of duration specified by the Company and an underwriter of Ordinary
Shares or other securities of the Company, following the effective date of a
registration statement of the Company filed under the Securities Act, it shall
not, to the extent requested by the Company and such underwriter, directly or
indirectly sell, offer to sell, contract to sell (including, without limitation,
any short sale), grant any option to purchase or otherwise transfer or dispose
of (other than to donees who agree to be similarly bound) any securities of the
Company held by it at any time during such period except Ordinary Shares
included in such registration; provided, however, that:

               (a)    all officers and directors of the Company enter into
similar agreements; and

               (b)    the Company shall use all reasonable efforts to obtain a
similar covenant from all holders of at least 1% of the Company's outstanding
securities;

               (c)    such market stand-off time period shall not exceed one
hundred eighty (180) days except as may be agreed by holders of a majority of
the then outstanding Registrable Securities.

        Each Holder agrees to provide to the other underwriters of any public
offering such further agreement as such underwriter may require in connection
with this market stand-off agreement. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of each Holder (and the shares or securities of every
other person subject to the foregoing restriction) until the end of such period.

        16.    TERMINATION OF REGISTRATION RIGHTS. The rights granted and
obligations imposed pursuant to Sections 1 through 15 of this Agreement shall
terminate as to any Holder at such time as such Holder beneficially owns less
than 1% of the Company's outstanding capital stock.

        17.    RIGHT OF FIRST REFUSAL FOR ISSUANCE OF NEW SECURITIES. The
Company hereby grants to each Major Holder the right of first refusal to
purchase a Pro Rata Share (as defined below) of any New Securities (as defined
in subsection 17(a)) which the Company may, from time to time, propose to sell
and issue. A "PRO RATA SHARE," for purposes of this right of first refusal,
shall be a fraction, the numerator of which is the sum of the number of shares
of Ordinary Shares then held by such Major Holder or issuable to such Major
Holder upon conversion of the Preferred, Exchangeable Shares or Warrants held by
such Major Holder, and the denominator of which is the sum of the total number
of Ordinary Shares then outstanding and the number of Ordinary Shares issuable
upon conversion or exercise of all outstanding capital stock, options or
warrants convertible into or exercisable for Ordinary Shares (without giving
effect to up to 3,746,308 options available for grant pursuant to the Company's
option plan).

               (a)    Except as set forth below, "NEW SECURITIES" shall mean any
shares of capital stock of the Company, including Ordinary Shares and Preferred,
whether now authorized or not. Not withstanding the foregoing, "NEW SECURITIES"
does not include:

                      (i)    any dividend payable in Ordinary Shares or any
shares issued upon a subdivision or combination of Ordinary Shares;

                      (ii)   Ordinary Shares issued upon conversion of
outstanding equity securities of the Company, including the Preferred and the
Exchangeable Shares;

                      (iii)  Ordinary Shares, or options exercisable therefor,
including options outstanding on the date of this Agreement, issued pursuant to
any existing stock or option plan, as may be amended, or pursuant to a
compensatory stock or option plan which is hereafter approved by the Board of
Directors;

                      (iv)   securities issued in consideration for an
acquisition (whether by merger or otherwise) by the Company;

                      (v)    New Securities sold by the Company in an
underwritten or other public offering pursuant to an effective registration
statement or a prospectus under U.S. or Israeli securities laws;

                      (vi)   New Securities issued in connection with equipment
leases or secured debt financings;

                      (vii)  securities issued on exercise of options or
conversion of convertible securities where the original issuance of the option
or convertible security was subject to this right of first refusal; or



                                      -17-
<PAGE>   18



                      (viii) securities issued in a transaction where holders of
greater than (a) 66 2/3% of the Series D Preferred, (b) 66 2/3% of the Series
C-1 Convertible Preferred, (c) 50% of the Series B Preferred and (d) 50% of the
Series A Preferred, each agree that this right of first refusal will not apply.

               (b)    In the event that the Company proposes to undertake an
issuance of New Securities, it shall give each Major Holder written notice of
its intention, describing the type of New Securities, and the price and terms
upon which the Company proposes to issue the same. Each such Major Holder shall
have twenty (20) days from the date of receipt of any such notice to agree to
purchase up to its respective Pro Rata Share of such New Securities for the
price and upon the terms specified in the notice by giving written notice to the
Company and stating therein the quantity of New Securities to be purchased.

               (c)    In the event that such Major Holder fails to exercise the
right of first refusal within said fifteen (15) day period, the Company shall
have sixty (60) days thereafter to sell or enter into an agreement (pursuant to
which the sale of New Securities covered thereby shall be closed, if at all,
within thirty (30) days from the date of said agreement) to sell the New
Securities not elected to be purchased by such Major Holder at the price and
upon terms no more favorable to the purchasers of such securities than specified
in the Company's notice. In the event that the Company has not sold the New
Securities or entered into an agreement to sell the New Securities within said
sixty (60) day period (or sold and issued New Securities in accordance with the
foregoing within thirty (30) days from the date of said agreement), the Company
shall not thereafter issue or sell any New Securities without first offering
such securities in the manner provided above.

               (d)    The right of first refusal hereunder is not assignable, in
whole or in part, except (i) by a Major Holder that is a partnership to any of
its partners, (ii) by a Major Holder that is any venture capital group or fund
to an Affiliated entity or person, and (iii) by a Major Holder that is a
corporation to any of its shareholders, provided in any such case that the
transferee beneficially owns following such transfer a sufficient number of
shares of Registrable Securities to constitute a Major Holder.

               (e)    The right of first refusal granted under this Agreement
shall expire immediately prior to the closing of a Qualified IPO.

        18.    AFFIRMATIVE COVENANTS. The Company and each Purchaser hereby
covenant and agree as follows:

               18.1   Financial Information.

year, a consolidated balance sheet of the Company and its subsidiaries as of
such fiscal year end, consolidated statements of income and cash flow for such
fiscal year, audited and accompanied by the reports of the Company's certified
public accountants (which certified public accountant shall be a "BIG SIX"

available;

                      (c)    Copies of all filings made with the Commission; and

                      (d)    any other financial or other information available

properly related to such Major Holder's corporate status as a shareholder of the
Company.

               18.2   Confidential Information.

                      (a)    Each Major Holder agrees that any information
obtained by such Major Holder pursuant to Section 18.1 which is, or would
reasonably be perceived to be, proprietary to the Company or otherwise
confidential will not be disclosed without the prior written consent of the
Company. Notwithstanding the foregoing, each Major Holder may disclose such
information, on a need to know basis, to its employees, accountants or
attorneys, or to the employees, accountants or attorneys of its general partner
or investment manager (so long as each such person to whom confidential
information is disclosed agrees to keep such information confidential), in
compliance with a court order or when otherwise necessary to enforce any of the
Major Holder's rights hereunder. Such information may also be disclosed to a
Major Holder's constituent partners, members or shareholders (so long as each
such person to whom confidential information is disclosed agrees to keep such
information confidential). Each Major Holder further acknowledges and
understands that any information will not be utilized by such Major Holder in
connection with purchases and/or sales of the Company's securities except in
compliance with applicable state and federal antifraud statutes.

               18.3   Assignment of Rights to Financial Information. The rights
and obligations pursuant to Sections 18.1 and 18.2 may be assigned or otherwise
conveyed by any Major Holder, or by any subsequent transferee of any such rights
to a transferee, other than to a competitor or customer of the Company, upon
prior written notice to the Company, upon the transfer by such Major Holder of
at least 800,000 shares of Registrable Securities; provided, however, that the
Company shall not be obligated under Section 18.1 to provide to any transferee
information which it deems in good faith to be a trade secret or similar
confidential information.

necessary to maintain, preserve and renew its existence as a corporation
organized under the laws of Israel, preserve and keep in force and effect, and
cause each of its subsidiaries to preserve and keep in force and effect, all
licenses and permits necessary and material to the conduct of the business of
the Company and its consolidated subsidiaries, taken as a whole, and to maintain

respective properties in good repair, working order and condition (except for

Company carried on in connection therewith may be properly and advantageously
conducted at all times.

               18.5   Taxes. The Company will duly pay and discharge, and cause
each of its subsidiaries duly to pay and discharge, all taxes, assessments and
governmental charges upon or against the Company or its subsidiaries or their
respective properties, in each case before the same become delinquent and before
penalties accrue thereon, unless and to the extent that the same are being
contested in good faith and by appropriate proceedings and the Company and its
subsidiaries shall have set aside on their books adequate reserves with respect
thereto.

               18.6   Insurance. The Company will apply for and continue in
force, or cause to be applied for and continued in force, adequate insurance
covering the respective risks of the Company and its subsidiaries



                                      -20-
<PAGE>   21



of such types and in such amounts and with such deductibles as are customary for
other corporations engaged in similar lines of business and with good and
responsible insurance companies.

               18.7   Books and Accounts. The Company will, and will cause each
subsidiary to, maintain proper books of record and account in which full, true
and correct entries shall be made of its transactions and set aside on its books
from its earnings for each fiscal year all such proper reserves as in each case
shall be required in accordance with generally accepted accounting principles.

               18.8   Notice of Events Involving Securities. The Company will
give the Purchasers (a) within ten days thereafter, notice of the filing by the
Company with the Securities and Exchange Commission or with any national
securities exchange either an application to register any securities of the
Company pursuant to Section 12 of the Exchange Act, or a registration statement
under Section 5 of the Securities Act, relating to any securities of the
Company, and (b) as promptly as practicable after any acquisition by it or by
any subsidiary of any of the Company's equity securities in excess in one
transaction of 10% of the number of such securities then outstanding and, in any
event, at the close of each fiscal year, notice of all acquisitions by it or by
any subsidiary of any of the Company's equity securities, specifying the class
and number of such equity securities so acquired.

               18.9   Employee Benefit Plans. Neither the Company nor any ERISA
Affiliate (as defined in ERISA) will establish, maintain, contribute to or incur
an obligation to contribute to an Employee Benefit Plan which (i) is subject to
Title IV of ERISA or Section 412 of the Internal Revenue Code or (ii) provides,
or has any liability to provide, life insurance, medical or other employee
welfare benefits after retirement or termination of employment, except as may be
required by Section 4980B of the Internal Revenue Code or similar state laws.
Neither the Company nor any other person, including any fiduciary, will engage
in any transaction prohibited by Section 406 of ERISA or Section 4975 of the
Internal Revenue Code, which could subject the Company, any subsidiary of the
Company or any entity that the Company has an obligation to indemnify to any tax
or penalty imposed under Section 4975 of the Internal Revenue Code or Section
502 of ERISA.

receipt of written notice or other evidence reasonably satisfactory to the
Company of the loss, theft, destruction or mutilation of any of the Company's
shares and, in the case of any such loss, theft or destruction, upon receipt of
a Purchaser's unsecured indemnity agreement, or in the case of any such
mutilation upon surrender and cancellation of such shares, the Company, at the
Company's expense, will make and deliver a new certificate in lieu of the lost,
stolen, destroyed or mutilated certificate carrying the same rights and
obligations as the original certificate. The Company will also pay the cost of
all deliveries of certificates for such shares to such Purchaser (including the
cost of insurance against loss or theft in an amount satisfactory to the
holders) upon any exchange thereof.

               18.11  Compliance with Environmental Laws. The Company will use
its best efforts not, and will cause each subsidiary to use its best efforts
not, except in any such case in compliance with applicable Environmental Laws
and except to the extent such activity or the consequences therefore shall not

and its subsidiaries, taken as a whole, (a) to use any of the property of the
Company or any subsidiary or any portion thereof for the handling, processing,
storage or disposal of Hazardous Substances, (b) to cause or permit to be
located on any of such property any underground tank or other underground
storage receptacle for Hazardous Substances, (c) to generate any Hazardous

<PAGE>   22



Substance on, upon or into such property, or (e) to otherwise conduct any
activity on such property or use any property in any manner that would expose
the Company or any subsidiary to material liability under any Environmental
Laws.

               local judgments, decrees, orders, laws, licenses, ordinances,
               rules or regulations pertaining to environmental matters in any
               jurisdiction (whether in the United States, Israel or elsewhere)
               in which the Company or any subsidiary is located.

                      "Hazardous Substances" shall mean any and all hazardous
               wastes that in any physical state might represent danger to the
               environmental balance because of their corrosive, toxic,

               irritating conditions, such as: (a) any petroleum or petroleum
               products, flammable explosives, radioactive materials, asbestos

        20.    MISCELLANEOUS.

               20.1   Aggregation of Shares. For purposes of any provision of
this Agreement requiring a person or entity to hold a minimum number of shares
of Preferred or Exchangeable Shares (or Ordinary Shares issued upon conversion
thereof) or Registrable Securities in order to gain the benefit of such
provision, all shares beneficially owned by Affiliated entities or persons
(including partners and constituent members and former partners and former
constituent members) shall be aggregated together for the purposes of
determining such Holder's status or rights under such provision. For purposes of
this Section 20.1, Bayview shall be deemed an affiliate of Evergreen.

               20.2   Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Israel with respect to
matters of corporate law and the State of California with respect to all other
matters; provided, however, that (notwithstanding the foregoing) Section 18 of
this Agreement shall be governed and construed in accordance with the laws of
the State of California, and the Company hereby consents to the jurisdiction of
of any state or federal court in Santa Clara County, California arising out of
or in connection with Section 18 hereof. Each of the Purchasers and the Company
hereby submits to the nonexclusive jurisdiction of the courts in Tel Aviv,
Israel or the United States District Court for the Northern District of
California or any California state court sitting in Santa Clara County,
California, as the case may be, for purposes of all legal proceedings arising
out of or relating to this Agreement and the transactions contemplated hereby.
Each of the Purchasers and the Company irrevocably waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying
of the venue of any such proceeding brought in such a court and any claim that
any such proceeding brought in such a court has been brought in an inconvenient
forum.

               20.3   Survival. The representations, warranties, covenants and
agreements made herein shall survive any investigation made by any Purchaser of
the Series D Preferred and the closing of the transactions contemplated hereby.

               20.4   Successors and Assigns. Except as otherwise provided
herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, assigns, heirs, executors and administrators of the
parties hereto. Nothing in this Agreement, express or implied, is intended to
confer upon any party other than the parties hereto or their respective
successors and assigns any rights, remedies, obligations, or liabilities under
or by reason of this Agreement, except as expressly provided in this Agreement.

               20.5   (a)    Entire Agreement; Amendment. This Agreement and the
                      other documents delivered pursuant hereto constitute the
                      full and entire understanding and agreement between the
                      parties with regard to the subjects hereof and thereof,
                      and no party shall be liable or bound to any other party
                      in any manner by any warranties, representations or
                      covenants except as specifically set forth herein or
                      therein. In this regard, the parties to each of the Third
                      Rights Agreement and the Side Letters



                                      -23-
<PAGE>   24



agree that the Third Rights Agreement and the Side Letters are hereby terminated
and shall have no further force and effect, except only that, as between the
Company and GE, the GE Side Letter shall continue to remain in full force and
effect and as between the Company and all of the Series D Holders, the
representations and warranties contained in the side letter dated May 6, 1998
between the Company and the Series D Holders shall survive as set forth in
paragraph 3 thereof. Except as expressly provided herein, neither this Agreement
nor any term hereof may be amended, waived, discharged or terminated other than
by a written instrument signed by the party against whom enforcement of any such
amendment, waiver, discharge or termination is sought; provided, however, that
any provision of this Agreement may be amended, waived or modified with the
written consent of (i) the Company, (ii) the holders of at least a majority of
the Series B Preferred (and Ordinary Shares issued upon conversion thereof) then
outstanding, (iii) the holders of at least 66 2/3% of the Series C-1 Convertible
Preferred (and Ordinary Shares issued upon conversion thereof) then outstanding,
(iv) the holders of at least 66 2/3% of the Series D Convertible Preferred (and
Ordinary Shares issued upon conversion thereof) then outstanding, and (v) the
holders of at least a majority of the Exchangeable Shares (and Ordinary Shares
issued upon conversion thereof) then outstanding and having rights pursuant to
this Agreement.

                      (b)    Additional Parties. The Company and the
Shareholders whose signatures appear on the signature page hereto agree that
should the Company sell additional shares of Series D Preferred to Additional
Purchasers (as defined in the Purchase Agreement), such Additional Purchasers
shall, after executing copies of this Agreement as an additional Purchaser
hereunder, become Shareholders hereunder and shall have all rights of
Shareholders hereunder.

               20.6   Notices. All notices and other communications required or
permitted hereunder shall be in writing, shall be effective when given, and
shall in any event be deemed to be given upon receipt or, if earlier, (a) five
(5) days after deposit with the U.S. Postal Service or other applicable postal
service, if delivered by first class mail, postage prepaid if addressed to a
party in the same country or twenty (20) days after deposit with the U.S. Postal
Service or other applicable postal service, if delivered by first class mail,
postage prepaid if addressed to a party in a different country, (b) upon
delivery, if delivered by hand, (c) two (2) business day after the business day
of deposit with Federal Express or similar overnight courier, freight prepaid or
(d) one (1) business day after the business day of facsimile transmission, if
delivered by facsimile transmission with copy by first class mail, postage
prepaid, and shall be addressed (i) if to a Purchaser, at such Purchaser's
address as set forth in the Purchase Agreement other than for the Exchangeable
Share Holders whose address shall be as set forth in the records of the Company,
and (ii) if to the Company, at the address of its principal corporate offices
(attention: Secretary), or at such other address as a party may designate by ten
days' advance written notice to the other party pursuant to the provisions
above.

               20.7   Delays or Omissions. Except as expressly provided herein,
no delay or omission to exercise any right, power or remedy accruing to any
Holder of any Registrable Securities, upon any breach or default of the Company
under this Agreement, shall impair any such right, power or remedy of such
Holder nor shall it be construed to be a waiver of any such breach or default,
or an acquiescence therein, or of or in any similar breach or default thereafter
occurring; nor shall any waiver of any single breach or default be deemed a
waiver of any other breach or default theretofore or thereafter occurring. Any
waiver, permit, consent or approval of any kind or character on the part of any
Holder of any breach



                                      -24-
<PAGE>   25



or default under this Agreement, or any waiver on the part of any Holder of any
provisions or conditions of this agreement, must be in writing and shall be
effective only to the extent specifically set forth in such writing. All
remedies, either under this Agreement or by law or otherwise afforded to any
Holder, shall be cumulative and not alternative.

               20.8   Enforcement of Covenants. The Company hereby acknowledges
that remedies at law may be inadequate to protect the Purchasers against any
actual or threatened breach by the Company or any of its subsidiaries of the
covenants contained in Section 18 hereof and agree that the Purchasers shall be
entitled to seek specific performance of such covenants and injunctive or other
equitable relief as a remedy for any such breach; the Company further agrees to
waive any requirement for the securing or posting of any bond in connection with
such remedy. Such remedy shall not be deemed to be the exclusive remedy for the
breach of such covenants, but shall be in addition to all other remedies
available to the Purchasers at law or equity.

               20.9   Counterparts. This Agreement may be executed in any number
of counterparts, each of which may be executed by less than all of the
Purchasers, each of which shall be enforceable against the parties actually
executing such counterparts, and all of which together shall constitute one
instrument.

               20.10  Severability. In the event that any provision of this
Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force and
effect without said provision; provided that no such severability shall be

                    LIQUIDITY PROPOSAL, BACKWEB TECHNOLOGIES

LOCKUP          Each holder of exchangeable shares will execute the
                underwriters' standard lock-up agreement, establishing a lockup
                period for 180 days following the IPO. This lock-up will be
                effective only if the Company and its underwriters' obtain a
                180-day lock-up from holders of at least 90% of the outstanding
                shares in the aggregate, excluding for the calculation the
                exchangeable shares Moreover, the Company and its underwriters
                will agree that no BackWeb shareholder's lock-up will be
                released without releasing the former holders of exchangeable
                shares (and the associated BackWeb shares) to a proportionate
                extent, and the Company will provide prompt notice of any such
                release to each exchangeable share holder. The Company also
                requests that each exchangeable share holder execute the
                Company's Fourth Amended and Restated Rights Agreement and
                Fourth Amended and Restated Shareholders Agreement.


LIQUIDITY       Each holder of exchangeable shares who agrees to these
RIGHT           procedures will receive the following from the Company:

                The Company will commit to obtain, if possible, a no-action
                letter from the Securities and Exchange Commission indicating
                that the Rule 144 holding period commenced effective as of the
                date of the acquisition. This will enable holders of
                exchangeable shares to sell their BackWeb shares into the public
                market, following expiration of the 180-day lock-up. If the
                Company is unable to obtain such a no-action letter in a timely
                manner, then the Company will reinstate each such holder's
                registration rights under the Rights Agreement (notwithstanding
                that the holder might own less than 1% of the outstanding
                shares).

                The registration rights would be on the terms and conditions of
                the existing Rights Agreement, except (i) as noted above, the 1%
                limitation will not apply, (ii) the Company will commence the
                process of a demand registration on Form S-1/F-1, on behalf of
                the holders of exchangeable shares, 30 days before the end of
                the 180-day lock up period, and will use its best efforts to
                cause the registration statement to become effective at the
                expiration of the lock-up or as soon thereafter as possible
                (subject to the existing limitations in the Rights Agreement,
                except that the threshold requirements for triggering a demand
                registration will not be required), and (iii) the Company will
                use its best efforts to cause a registration statement on Form
                S-3/F-3 to be effective one year following the effective date of
                the Company's initial public offering (or as soon thereafter as
                possible), covering all BackWeb shares issued or issuable in
                respect of the exchangeable shares and not previously sold into
                the public market (regardless of any threshold requirements
                stated in the Rights Agreement for the number of shares or
                dollar value of shares proposed to be sold). These rights will
                be subject to the limitations in the registration rights
                agreement, including the coexisting pro rata rights of other
                holders.

IF THIS IS ACCEPTABLE, PLEASE INDICATE YOUR AGREEMENT HERE:

SHAREHOLDER:                                BACKWEB TECHNOLOGIES, LTD.

Ladies and Gentlemen:

        We refer to the registration statement and amendments thereto on Form
F-1, registration no. 333-10358 (the "Registration Statement"), originally filed
on May 14, 1999 by BackWeb Technologies Ltd. (the "Company") with the Securities
and Exchange Commission under the Securities Act of 1933, as amended, in
connection with the sale of up to 5,500,000 Ordinary Shares, nominal value NIS
0.01 per share, of the Company (the "Shares") to the Underwriters as described
in the Registration Statement for resale to the public. The Company will issue
and sell these 5,500,000 Shares. The underwriters may, as described in the
Registration Statement, purchase up to an additional 825,000 Ordinary Shares,
nominal value NIS 0.01 per share (the "Additional Shares") from the Company at
the initial public offering price less the underwriting discount.

        As special Israeli counsel to the Company in connection with the
offering of the Shares pursuant to the Registration Statement, we have examined
such corporate records and documents and such questions of law as we have
considered necessary or appropriate for the purpose of this opinion. Upon the
basis of such examination, we are of the opinion that the Shares and the
Additional Shares to be issued and sold by the Company, as contemplated by the
Prospectus included in the Registration Statement, are duly and validly
authorized and, when issued and sold in the manner contemplated by the
Underwriting Agreement filed as an exhibit to the Registration Statement (the
"Underwriting Agreement") and upon receipt by the Company of payment therefor as
provided in the Underwriting Agreement, will be legally and validly issued,
fully paid and non-assessable.

        We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the Prospectus contained in the Registration Statement and
elsewhere in the Registration Statement and Prospectus.



                                            Very truly yours,



                                            Naschitz, Brandes & Co.

             BACKWEB TECHNOLOGIES LTD. (THE "COMPANY" OR "BACKWEB")
              SUMMARY OF 1996 ISRAELI EMPLOYEES STOCK OPTION PLAN

In 1996 the company's Board of Directors adopted an Employee Stock Option Plan
(the "Plan"). The Plan is divided into two separate Plans. The first plan --
adopted pursuant to Section 102 of the Israeli Income Tax Ordinance (the
"Ordinance"), and the second -- adopted pursuant to Section 3(9) of the
Ordinance ("Plan-I" and "Plan II", respectively).

According to the Plan I the company may grant its employees, for no
consideration, non transferable options to purchase same number of common stock
of the company, nominal value NIS 0.01 (which number shall be adjusted for
bonus shares). Such options regularly vest in four equal installments over a
four year period, at an exercise price determined by the Board of Directors
from time to time, and are subject to a lock up period of 24 months during
which such options or any shares issued upon exercise are held by a trustee.

According to the Plan, each employee is required to sign an irrevocable proxy
granting Naschitz Brandes & Co. the right to participate and vote on his/her
behalf at all company shareholders meetings and general meetings. This proxy
shall expire upon the earlier of (i) a consummation of an IPO, or (ii) a merger
and/or change in control and/or sale of the company to a third party.

The rights to options or shares which have not yet vested pursuant to Plan I
shall expire in the event that the employee's employment in the company is

                               GENERAL PROVISIONS


I.      PURPOSE OF THE PLAN

                This 1996 United States Stock Option Plan is intended to
promote the interests of BackWeb Technologies Ltd., an Israeli corporation, by
providing eligible persons with the opportunity to acquire a proprietary
interest, or otherwise increase their proprietary interest, in the Corporation
as an incentive for them to remain in the service of the Corporation.

                Capitalized terms shall have the meanings assigned to such
terms in the attached Appendix.

II.     ADMINISTRATION OF THE PLAN

        A.      Administration of the Plan may, at the Board's discretion, be
vested in the Committee, or the Board may retain the power to administer the
Plan with respect to all persons. The members of the Committee may be Board
members who are Employees eligible to receive discretionary option grants under
the Plan or any stock option, stock appreciation, stock bonus or other stock
plan of the Corporation (or any other member of the BRM Group).

        B.      Members of the Committee shall serve for such period of time as
the Board may determine and shall be subject to removal by the Board at any
time. The Board may also at any time terminate the functions of the Committee
and reassume all powers and authority previously delegated to such Committee.

        C.      The Plan Administrator shall, within the scope of its
administrative functions under the plan, have full power and authority to
establish such rules and regulations as it may deem appropriate for proper
administration of the Plan and to make such determinations under, and issue
such interpretations of, the provisions of such Plan and any outstanding
options thereunder as it may deem necessary or advisable. Decisions of the Plan
Administrator within the scope of its administrative functions under the Plan
shall be final and binding on all parties who have an interest in the Plan
under its jurisdiction or any option thereunder.

        D.      Service on the Committee shall constitute service as a Board
member, and members of each such committee shall accordingly be entitled to
full indemnification and


                                       1
<PAGE>   2
reimbursement as Board members for their service on such committee. No member of
the Committee shall be liable for any act or omission made in good faith with
respect to the Plan or any option grants made under the Plan.

III. ELIGIBILITY

     A.   The persons eligible to participate in the Plan are as follows:

          (i)       employees of the BRM Group,

          (ii)      non-employee members of the board of directors of any member
of the BRM Group, and

          (iii)     consultants and other independent advisors who provide
services to the Corporation (or any other member of the BRM Group).

     B.   The Plan Administrator shall, within the scope of its administrative
jurisdiction under the Plan, have full authority (subject to the provisions of
the Plan) to determine, with respect to the option grants under the Plan, which
eligible persons are to receive option grants, the time or times when such
option grants are to be made, the number of shares to be covered by each such
grant, the status of the granted option as either an Incentive Option or a
Non-Statutory Option, the time or times at which each option is to become
exercisable and the vesting schedule (if any) applicable to the option shares
and the maximum term for which the option is to remain outstanding.

IV.  SHARES SUBJECT TO THE PLAN

     A.   The shares issuable under the Plan shall be authorized but unissued
Ordinary Shares. The maximum number of Ordinary Shares which may be issued over
the term of the Plan shall not exceed 12,460,067 shares.

     B.   Ordinary Shares subject to outstanding options shall be available for
subsequent issuance under the Plan to the extent (i) the options expire or
terminate for any reason prior to exercise in full or, (ii) the options are
canceled in accordance with the cancellation-regrant provisions of Article Two.
All shares issued under the Plan, whether or not those shares are subsequently
purchased by the Corporation or its designee pursuant to the purchase rights
under the Plan, shall reduce on a share-for-share basis the number of Ordinary
Shares available for subsequent issuance under the Plan.

     C.   Should any change be made to the Ordinary Shares (or, prior to the
Section 12(g) Registration Date, to the Corporation's equity securities into
which the Ordinary Shares are convertible on the Section 12(g) Registration
Date) by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Ordinary Shares (or, prior to the Section 12(g) Registration Date,
to the Corporation's equity securities into which the Ordinary Shares

                                       2
<PAGE>   3
are convertible on the Section 12(g) Registration Date) as a class without the
Corporation's receipt of consideration, appropriate adjustments shall be made to
(i) the maximum number and/or class of securities issuable under the Plan, (ii)
the number and/or class of securities for which any one person may be granted
options per calendar year or over the term of the Plan, and (iii) the number
and/or class of securities and the exercise price per share in effect under each
outstanding option in order to prevent the dilution or enlargement of benefits
thereunder. The adjustments determined by the Plan Administrator shall be final,
binding and conclusive.

                                  ARTICLE TWO
                              OPTION GRANT PROGRAM

I.   OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator, provided, however, that each such document
shall comply with the terms specified below. Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

     A.   EXERCISE PRICE.

          1.   The exercise price per share shall be fixed by the Plan
Administrator but shall not be less than eighty-five percent (85%) of the Fair
Market Value per Ordinary Share on the option grant date.

          2.   The exercise price shall become immediately due upon exercise of
the option and shall, subject to the provisions of Section I of Article Three
and the documents evidencing the option, be payable in cash or check made
payable to the Corporation. The option may also be exercised for vested shares
through a special sale and remittance procedure pursuant to which the Optionee
shall concurrently provide irrevocable written instructions to (a) a
Corporation-designated brokerage firm to effect the immediate sale of the
purchased shares and remit to the Corporation, out of the sale proceeds
available on the settlement date, sufficient funds to cover the aggregate
exercise price payable for the purchased shares plus all applicable Israeli and
Federal, state and local income and employment taxes required to be withheld by
the Corporation by reason of such exercise, and (b) the Corporation to deliver
the certificates for the purchased shares directly to such brokerage firm in
order to complete the sale transaction. Except to the extent the sale and
remittance procedure is used, payment of the exercise price for the purchased
shares must be made on the Exercise Date.

     B.   EXERCISE AND TERM OF OPTIONS. Each option shall be exercisable at such
time or times, during such period and for such number of shares as shall be
determined by

                                       3
<PAGE>   4

the Plan Administrator and set forth in the documents evidencing the option.
However, no option shall have a term in excess of seven (7) years measured from
the option grant date.

     C.   EFFECT OF TERMINATION OF SERVICE.

          1.   The following provisions shall govern the exercise of any
options held by the Optionee at the time of cessation of Service or death:

               (i)   Any option exercisable in whole or in part at the time of
the Optionee's cessation of Service for any reason shall remain exercisable for
a period of 50 days following such cessation of Service, but no such option
shall be exercisable after the expiration of the option term.

               (ii)  Any option exercisable in whole or in part by the Optionee
at the time of death may be subsequently exercised by the personal
representative of the Optionee's estate or by the person or persons to whom the
option is transferred pursuant to the Optionee's will or in accordance with the
laws of descent and distribution.

               (iii) During the applicable post-Service exercise period, the
option may not be exercised in the aggregate for more than the number of vested
shares for which the option is exercisable on the date of the Optionee's
cessation of Service. Upon the expiration of the applicable exercise period or
(if earlier) upon the expiration of the option term, the option shall terminate
and cease to be outstanding for any vested shares for which the option has not
been exercised. However, the option shall, immediately upon the Optionee's
cessation of Service, terminate and cease to be outstanding to the extent it is
not exercisable for vested shares on the date of such cessation of Service.

               (iv)  Should the Optionee's Service be terminated for
Misconduct, then all outstanding options held by the Optionee shall terminate
immediately and cease to be outstanding.

               (v)   In the event of a Corporate Transaction, the provisions of
Section III of this Article Two shall govern the period for which the
outstanding options are to remain exercisable following the Optionee's
cessation of Service and shall supersede any provisions to the contrary in this
section.

          2.   The Plan Administrator shall have the discretion, exercisable
either at the time an option is granted or at any time while the option remains
outstanding, to:

               (i)  extend the period of time for which the option is to remain
exercisable following the Optionee's cessation of Service from the period
otherwise in effect for that option to such greater period of time as the
Plan Administrator shall deem appropriate, but in no event beyond the
expiration of the option term, and/or



                                       4

<PAGE>   5
          (ii)  permit the option to be exercised, during the applicable
post-Service exercise period, not only with respect to the number of vested
Ordinary Shares for which such option is exercisable at the time of the
Optionee's cessation of Service but also with respect to one or more additional
installments in which the Optionee would have vested under the option had the
Optionee continued in Service.

     D.   SHAREHOLDER RIGHTS. The holder of an option shall have no shareholder
rights with respect to the shares subject to the option until such person shall
have exercised the option, paid the exercise price and become a holder of the
purchased shares.

     E.   RIGHT OF FIRST REFUSAL. Should an Optionee who has exercised Options
or Ordinary Shares wish to sell or otherwise transfer his or her Ordinary
Shares acquired upon the exercise of Options prior to the Section 12(g)
Registration Date, the Corporation or its designee shall have a right of first
refusal on such Ordinary Shares. The terms upon which such right of first
refusal shall be exercisable (including the periods and procedures for
exercise) shall be established by the Plan Administrator and set forth in the
document evidencing such right of first refusal.

     F.   LIMITED TRANSFERABILITY OF OPTIONS. During the lifetime of the
Optionee, the options shall be exercisable only by the Optionee and shall not
be assignable or transferable other than by will or by the laws of descent and
distribution following the Optionee's death. However, a Non-Statutory Option may
be assigned (i) to a member of the immediate family of the Optionee or to a
trust established for the benefit of one or more members of the immediate family
of the Optionee, provided that the assignment shall not be effective until
approved in writing by the Plan Administrator, or (ii) in accordance with terms
approved in advance by the Plan Administrator. The terms applicable to the
assigned option (or portion thereof) shall be the same as those in effect for
the option immediately prior to such assignment and shall be set forth in such
documents issued to the assignee as the Plan Administrator may deem appropriate.

II.  INCENTIVE OPTIONS

     The terms specified below shall be applicable to all Incentive Options.
Except as modified by the provisions of this Section II, all the provisions of
Articles One, Two and Three shall be applicable to Incentive Options. Options
which are specifically designated as Non-Statutory Options when issued under
the Plan shall not be subject to the terms of this Section II.

     A.   ELIGIBILITY. Incentive Options may be granted only to Employees.

     B.   EXERCISE PRICE. The exercise price per share shall not be less
than one hundred percent (100%) of the Fair Market Value per Ordinary Share on
the option grant date.


                                       5
<PAGE>   6
     C.    TEN PERCENT SHAREHOLDER. To the extent required by Code Section 422,
if any Employee to whom an Incentive Option is granted is a Ten Percent
Shareholder, then the exercise price per share shall not be less than one
hundred ten percent (110%) of the Fair Market Value per Ordinary Share on the
option grant date, and the option term shall not exceed five (5) years measured
from the option grant date.

III. CORPORATE TRANSACTION/CHANGE IN CONTROL

     A.   Immediately following the consummation of a Corporate Transaction,
all outstanding options shall terminate and cease to be outstanding, except to
the extent assumed by the successor corporation (or parent thereof).

     B.   The Plan Administrator shall have the discretion, exercisable either
at the time the option is granted or at any time while the Option remains
outstanding, to provide for the acceleration of one or more outstanding Options
upon the occurrence of a Corporate Transaction, whether or not those Options
are to be assumed or replaced (or those repurchase rights are to be assigned)
in the Corporate Transaction. The Plan Administrator shall have the discretion,
exercisable either at the time the Option is granted or at any time while the
Option remains outstanding, to (i) provide for the automatic acceleration of
one or more outstanding Options upon the occurrence of a Change in Control or
(ii) condition any such Option acceleration upon the subsequent Involuntary
Termination of the Optionee's Service within a specified period following the
effective date of such Change in Control. Any Options accelerated in connection
with a Change in Control shall remain fully exercisable until the expiration or
sooner termination of the Option term.

     C.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to (i) the number and class of
securities available for issuance under the Plan on both an aggregate and per
Optionee basis following the consummation of such Corporate Transaction and (ii)
the exercise price payable per share under each outstanding option, provided the
aggregate exercise price payable for such securities shall remain the same.

     D.   The portion of any Incentive Option accelerated in connection with a
Corporate Transaction or Change in Control shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
limitation is not exceeded. To the extent the such dollar limitation is
exceeded, the accelerated portion of such option shall be exercisable as a
Non-Statutory Option under the Federal tax Laws.

     E.   The grant of options under the Plan shall in no way affect the right
of the Corporation to adjust, reclassify, reorganize or otherwise change its
capital or business


                                       6
<PAGE>   7
structure or to merge, consolidate, dissolve, liquidate or sell or transfer all
or any part of its business or assets.

IV.  CANCELLATION AND REGRANT OF OPTIONS

     The Plan Administrator shall have the authority to effect, at any time and
from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Plan and to grant in
substitution new options covering the same or different number of Ordinary
Shares but with an exercise price per share based on the Fair Market Value per
Ordinary Share on the new option grant date.

                                 ARTICLE THREE
                                 MISCELLANEOUS

I.   FINANCING

     A.   The Plan Administrator may permit any Optionee to pay the option
exercise price under the Plan by delivering a promissory note payable in one or
more installments. The terms of any such promissory note (including the
interest rate and the terms of repayment) shall be established by the Plan
Administrator in its sole discretion. Promissory notes may be authorized with
or without security or collateral. In all events, the maximum credit available
to the Optionee may not exceed the sum of (i) the aggregate option exercise
price payable for the purchased shares, plus (ii) any Israeli and United States
Federal, state and local income and employment tax liability incurred by the
Optionee in connection with the option exercise.

     B.   The Plan Administrator may, in its discretion, determine that one or
more such promissory notes shall be subject to forgiveness by the Corporation
in whole or in part upon such terms as the Plan Administrator may deem
appropriate.

II.  EFFECTIVE DATE AND TERM OF THE PLAN

     A.   The Plan shall become effective on the Plan Effective Date and
options may be granted under the Plan from and after the Plan Effective Date.
However, no options granted under the Plan may be exercised until the Plan is
approved by the Corporation's shareholders. If such shareholder approval is not
obtained within twelve (12) months after the Plan Effective Date, then all
options previously granted under this Plan shall terminate and cease to be
outstanding, and no further options shall be granted and no shares shall be
issued under the Plan.

     B.   The Plan shall terminate upon the earliest of (i) November 1, 2006,
(ii) the date on which all shares available for issuance under the Plan shall
have been issued pursuant to the exercise of the options under the Plan, or
(iii) the termination of all out-


                                       7


<PAGE>   8

standing options in connection with a Corporate Transaction. Upon such Plan
termination, all options outstanding on such date shall thereafter continue to
have force and effect in accordance with the provisions of the documents
evidencing such options.

III.  AMENDMENT OF THE PLAN

      A.    The Board shall have complete and exclusive power and authority to
amend or modify the Plan in any or all respects. However, no such amendment or
modification shall adversely affect the rights and obligations with respect to
options at the time outstanding under the Plan unless the Optionee consents to
such amendment or modification. In addition, the Board shall not, without the
approval of the Corporation's shareholders, (i) materially increase the maximum
number of shares issuable under the Plan or the maximum number of shares for
which any one person may be granted options in the aggregate over the term of
the Plan, except for permissible adjustments in the event of certain changes in
the Corporation's capitalization, (ii) materially modify the eligibility
requirements for Plan participation, or (iii) materially increase the benefits
accruing to Plan participants.

      B.    Options to purchase Ordinary Shares may be granted under the Plan
that are in excess of the number of shares then available for issuance under
the Plan, provided any excess shares actually issued under those programs are
held in escrow until there is obtained shareholder approval of an amendment
sufficiently increasing the number of Ordinary Shares available for issuance
under the Plan. If such shareholder approval is not obtained within twelve (12)
months after the date the first such excess issuances are made, then (i) any
unexercised options granted on the basis of such excess shares shall terminate
and cease to be outstanding, and (ii) the Corporation shall promptly refund to
the Optionees the exercise price paid for any excess shares issued under the
Plan and held in escrow, without interest, and such shares shall thereupon be
automatically canceled and cease to be outstanding.

IV.   USE OF PROCEEDS

           Any cash proceeds received by the Corporation from the sale of
Ordinary Shares under the Plan shall be used for general corporate purposes.

V.    REGULATORY APPROVALS

      A.    All of the provisions of this Plan are subject to the provisions of
Israeli law. Any provision of this Plan that is inconsistent with Israeli law
shall be deemed to be stricken from the Plan, without affecting the validity of
any other provision.

      B.    The implementation of the Plan, the granting of any option under
the Plan and the issuance of any Ordinary Shares upon the exercise of any
option shall be subject to the Corporation's procurement of all approvals and
permits required by regulatory



                                       8
<PAGE>   9
authorities having jurisdiction over the Plan, the options granted under it and
the Ordinary Shares issued pursuant to it.

      C.    No Ordinary Shares or other assets shall be issued or delivered
under the Plan unless and until there shall have been compliance with all
applicable requirements of Israeli law and United States Federal and state
securities laws, and all applicable listing requirements of any Stock Exchange
(or Nasdaq, if applicable) on which the Ordinary Shares are then listed for
trading.

VI.   NO EMPLOYMENT/SERVICE RIGHTS

            Nothing in the Plan shall confer upon the Optionee any right to
continue in Service for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Corporation (or any other
member of the BRM Group employing or retaining such person) or of the Optionee,
which rights are hereby expressly reserved by each, to terminate such person's
Service at any time for any reason, with or without cause.

     Options granted under the Plan may be Incentive Stock Options or

      (b)   Powers of the Administrator. Subject to the provisions of the Plan,
and in the case of a Committee, subject to the specific duties delegated by the

           (ii)   to select the Service Providers to whom Options and Stock

Such terms and conditions include, but are not limited to, the exercise price,
the time or times when Options or Stock Purchase Rights may be exercised (which
may be based on performance criteria), any vesting acceleration or waiver of
forfeiture restrictions, and any restriction or limitation regarding any Option
or Stock Purchase Right or the shares of Common Stock relating thereto, based
in each case on such factors as the Administrator, in its sole discretion,
shall determine;

           (vi)  to reduce the exercise price of any Option or Stock Purchase
Right to the then current Fair Market Value if the Fair Market Value of the
Common Stock covered by such Option or Stock Purchase Right shall have declined
since the date the Option or Stock Purchase Right was granted;

          (vii)  to institute an Option Exchange Program;

granted pursuant to the Plan;

<PAGE>   6
                  (xi)  to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option or Stock Purchase Right that number of Shares
having a Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld shall be determined on the date that
the amount of tax to be withheld is to be determined. All elections by an
Optionee to have Shares withheld for this purpose shall be made in such form and
under such conditions as the Administrator may deem necessary or advisable;

                 (xii)  to authorize any person to execute on behalf of the
Company any instrument required to effect the grant of an Option or Stock
Purchase Right previously granted by the Administrator;

                (xiii)  to make all other determinations deemed necessary or
advisable for administering the Plan.

            (c)   Effect of Administrator's Decision. The Administrator's
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options or Stock Purchase Rights.

      5.    Eligibility.  Nonstatutory Stock Options and Stock Purchase Rights
may be granted to Service Providers. Incentive Stock Options may be granted
only to Employees.

      6.    Limitations.

            (a)   Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value on the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

            (b)   Neither the Plan nor any Option or Stock Purchase Right shall
confer upon an Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall they interfere
in any way with the Optionee's right or the Company's right to terminate such
relationship at any time, with or without cause.

            (c)   The following limitations shall apply to grants of Options;

                  (i)   No Service Provider shall be granted, in any fiscal year
of the Company, Options to purchase more than 500,000 Shares.


                                      -6-















<PAGE>   7
          (ii)  In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional 500,000 Shares
which shall not count against the limit set forth in subsection (i) above.

          (iii) The foregoing limitations shall be adjusted proportionately in
connection with any change in the Company's capitalization as described in
Section 13.

          (iv) If an Option is cancelled in the same fiscal year of the Company
in which it was granted (other than in connection with a transaction described
in Section 13), the cancelled Option will be counted against the limits set
forth in subsections (i) and (ii) above. For this purpose, if the exercise
price of an Option is reduced, the transaction will be treated as a cancellation
of the Option and the grant of a new Option.

     7.   Term of Plan.  Subject to Section 19 of the Plan, the Plan shall
become effective upon its adoption by the Board. It shall continue in effect for
a term of ten (10) years unless terminated earlier under Section 15 of the Plan.

     8.   Term of Option.  The term of each Option shall be stated in the
Option Agreement. In the case of an Incentive Stock Option, the term shall be
ten (10) years from the date of grant or such shorter term as may be provided
in the Option Agreement. Moreover, in the case of an Incentive Stock Option
granted to an Optionee who, at the time the Incentive Stock Option is granted,
owns stock representing more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
term of the Incentive Stock Option shall be five (5) years from the date of
grant or such shorter term as may be provided in the Option Agreement.

     9.   Option Exercise Price and Consideration.

          (a)  Exercise Price.  The per share exercise price for the Shares to
be issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

               (i)  In the case of an Incentive Stock Option

                    (A) granted to an Employee who, at the time the Incentive
Stock Option is granted, owns stock representing more than ten percent (10%) of
the voting power of all classes of stock of the Company or any Parent or
Subsidiary, the per Share exercise price shall be no less than 110% of the Fair
Market Value per Share on the date of grant.

                    (B) granted to any Employee other than an Employee
described in paragraph (A) immediately above, the per Share exercise price
shall be no less than 100% of the Fair Market Value per Share on the date of
grant.



                                      -7-
<PAGE>   8
          (ii)   In the case of a Nonstatutory Stock Option, the per Share
exercise price shall be determined by the Administrator. In the case of a
Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

          (iii)  Notwithstanding the foregoing, Options may be granted with a
per Share exercise price of less than 100% of the Fair Market Value per Share on
the date of grant pursuant to a merger or other corporate transaction.

     (b)  Waiting Period and Exercise Dates. At the time an Option is granted,
the Administrator shall fix the period within which the Option may be exercised
and shall determine any conditions which must be satisfied before the Option may
be exercised.

     (c)  Form of Consideration. The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment. In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant. Such
consideration may consist entirely of:

          (i)    cash;

          (ii)   check;

          (iii)  promissory note;

          (iv)   other Shares which (A) in the case of Shares acquired upon
exercise of an option, have been owned by the Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

          (v)    consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan;

          (vi)   a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement;

          (vii)  any combination of the foregoing methods of payment; or

          (viii) such other consideration and method of payment for the issuance
of Shares to the extent permitted by Applicable Laws.

<PAGE>   9
     10.  Exercise of Option.

          (a)  Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence. An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 13 of the Plan.

               Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

     (b)  Termination of Relationship as a Service Provider. If an Optionee
ceases to be a Service Provider, other than upon the Optionee's death or
Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement). In the absence of
a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination. If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

     (c)  Disability of Optionee. If an Optionee ceases to be a Service Provider
as a result of the Optionee's Disability, the Optionee may exercise his or her
Option within such period of time as is specified in the Option Agreement to the
extent the Option is vested on the date of termination (but in no event later
than the expiration of the term of such Option as set forth in the Option
Agreement). In the absence of a specified time in the Option Agreement, the
Option shall remain

                                      -9-
<PAGE>   10
exercisable for twelve (12) months following the Optionee's termination. If, on
the date of termination, the Optionee is not vested as to his or her entire
Option, the Shares covered by the unvested portion of the Option shall revert
to the Plan. If, after termination, the Optionee does not exercise his or her
Option within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

                (d)     Death of Optionee.  If an Optionee dies while a Service
Provider, the Option may be exercised within such period of time as is
specified in the Option Agreement (but in no event later than the expiration of
the term of such Option as set forth in the Notice of Grant), by the Optionee's
estate or by a person who acquires the right to exercise the Option by bequest
or inheritance, but only to the extent that the Option is vested on the date of
death. In the absence of a specified time in the Option Agreement, the Option
shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall immediately revert to the Plan. The Option may be exercised by the
executor or administrator of the Optionee's estate or, if none, by the
person(s) entitled to exercise the Option under the Optionee's will or the laws
of descent or distribution. If the Option is not so exercised within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

                (e)     Buyout Provisions.  The Administrator may at any time
offer to buy out for a payment in cash or Shares an Option previously granted
based on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

        11.     Stock Purchase Rights

                (a)  Rights to Purchase.  Stock Purchase Rights may be issued
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan.  After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing or electronically, by means of a Notice of Grant,
of the terms, conditions and restrictions related to the offer, including the
number of Shares that the offeree shall be entitled to purchase, the price to
be paid, and the time within which the offeree must accept such offer. The
offer shall be accepted by execution of a Restricted Stock Purchase Agreement
in the form determined by the Administrator.

                (b)  Repurchase Option.  Unless the Administrator determines
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's service with the Company for any reason (including death or
Disability). The purchase price of Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at a rate determined by the
Administrator.



                                      -10-
<PAGE>   11
                (c)  Other Provisions.  The Restricted Stock Purchase Agreement
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion.

                (d)  Rights as a Shareholder.  Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchaser is entered
upon the records of the duly authorized transfer agent of the Company. No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the Stock Purchase Right is exercised, except as provided
in Section 13 of the Plan.

        12.     Non-Transferability of Options and Stock Purchase Rights.
Unless determined otherwise by the Administrator, an Option or Stock Purchase
Right may not be sold, pledged, assigned, hypothecated, transferred, or
disposed of in any manner other than by will or by the laws of descent or
distribution and may be exercised, during the life time of the Optionee, only
by the Optionee. If the Administrator makes an Option or Stock Purchase Right
transferable, such Option or Stock Purchase Right shall contain such additional
terms and conditions as the Administrator deems appropriate.

        13.     Adjustments Upon Changes in Capitalization, Dissolution, Merger
or Asset Sale.

                (a)     Changes in Capitalization.  Subject to any required
action by the shareholders of the Company, the number of shares of Common Stock
covered by each outstanding Option and Stock Purchase Right, and the number of
shares of Common Stock which have been authorized for issuance under the Plan
but as to which no Options or Stock Purchase Rights have yet been granted or
which have been returned to the Plan upon cancellation or expiration of an
Option or Stock Purchase Right, as well as the price per share of Common Stock
covered by such outstanding Option or Stock Purchase Right, shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of issued shares of Common Stock effected
without receipt of consideration by the Company; provided, however, that
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." Such adjustment shall be
made by the Board, whose determination in that respect shall be final, binding
and conclusive. Except as expressly provided herein, no issuance by the Company
of shares of stock of any class, or securities convertible into shares of stock
of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number or price of shares of Common Stock subject to an
Option or Stock Purchase Right.

                (b)     Dissolution or Liquidation.  In the event of the
proposed dissolution or liquidation of the Company, the Administrator shall
notify each Optionee as soon as practicable prior to the effective date of such
proposed transaction. The Administrator in its discretion may provide for an
Optionee to have the right to exercise his or her Option until ten (10) days
prior to such transaction as to all of the Optioned Stock covered thereby,
including Shares as to which the Option would not


                                      -11-

<PAGE>   12
otherwise be exercisable. In addition, the Administrator may provide that any
Company repurchase option applicable to any Shares purchased upon exercise of
an Option or Stock Purchase Right shall lapse as to all such Shares, provided
the proposed dissolution or liquidation takes place at the time and in the
manner contemplated. To the extent it has not been previously exercised, an
Option or Stock Purchase Right will terminate immediately prior to the
consummation of such proposed action.

     (c)  Merger or Asset Sale.  In the event of a merger of the Company with or
into another corporation, or the sale of substantially all of the assets of the
Company, each outstanding Option and Stock Purchase Right shall be assumed or an
equivalent option or right substituted by the successor corporation or a Parent
or Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the Option or Stock Purchase
Right, the Optionee shall fully vest in and have the right to exercise the
Option or Stock Purchase Right as to all of the Optioned Stock, including Shares
as to which it would not otherwise be vested or exercisable. If an Option or
Stock Purchase Right becomes fully vested and exercisable in lieu of assumption
or substitution in the event of a merger or sale of assets, the Administrator
shall notify the Optionee in writing or electronically that the Option or Stock
Purchase Right shall be fully vested and exercisable for a period of fifteen
(15) days from the date of such notice, and the Option or Stock Purchase Right
shall terminate upon the expiration of such period. For the purposes of this
paragraph, the Option or Stock Purchase Right shall be considered assumed if,
following the merger or sale or assets, the option or right confers the right to
purchase or receive, for each Share of Optioned Stock subject to the Option or
Stock Purchase Right immediately prior to the merger or sale of assets, the
consideration (whether stock, cash, or other securities or property) received in
the merge or sale of assets by holders of Common Stock for each Share held on
the effective date of the transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of
the outstanding Shares); provided, however, that if such consideration received
in the merger or sale of assets is not solely common stock of the successor
corporation or its Parent, the Administrator may, with the consent of the
successor corporation, provide for the consideration to be received upon the
exercise of the Option or Stock Purchase Right, for each Share of Optioned Stock
subject to the Option or Stock Purchase Right, to be solely common stock of the
successor corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger or sale of
assets.

     14.  Date of Grant.  The date of grant of an Option or Stock Purchase
Right shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator. Notice of the determination shall
be provided to each Optionee within a reasonable time after the date of such
grant.

     15.  Amendment and Termination of the Plan.

          (a)  Amendment and Termination.  The Board may at any time amend,
alter, suspend or terminate the Plan.


                                      -12-

<PAGE>   13
          (b)  Shareholder Approval. The Company shall obtain shareholder
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

          (c)  Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to
exercise the powers granted to it hereunder with respect to Options granted
under the Plan prior to the date of such termination.

     16.  Conditions Upon Issuance of Shares.

          (a)  Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option or Stock Purchase Rights unless the exercise of such
Option or Stock Purchase Right and the issuance and delivery of such Share
shall comply with Applicable Laws and shall be further subject to the approval
of counsel for the Company with respect to such compliance.

          (b)  Investment Representations. As a condition to the exercise of an
Option or Stock Purchase Right, the Company may require the person exercising
such Option or Stock Purchase Right to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required.

     17.  Inability to Obtain Authority. The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company or any liability in respect
of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

     18.  Reservation of Shares. The Company, during the term of this Plan, will
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     19.  Shareholder Approval. The Plan shall be subject to approval by the
shareholders of the Company within twelve (12) months after the date the Plan
is adopted. Such shareholder approval shall be obtained in the manner and to
the degree required under Applicable Laws.

                           1998 US STOCK OPTION PLAN

                          STOCK OPTION GRANT AGREEMENT

To:  The Optionee named in the Notice of Grant of Stock Option ("Notice") to
which this Stock Option Grant Agreement ("Agreement") is attached.

1.   Grant of Option. BackWeb Technologies, Ltd. (the "Corporation") hereby
grants you an option ("the Option") to purchase the number of Ordinary Shares
of the Corporation ("Shares") set forth in the Notice of Grant ("Notice"), at
the exercise price per share ("Exercise Price") set forth in the Notice,
subject to the terms and conditions of the Corporation's 1998 United States
Stock Option Plan (the "Plan") (the 1998 Plan applies to grants made after
March 31, 1998). In the event of a conflict between the terms and conditions of
the Plan and the terms and conditions of this Agreement, the terms and
conditions of the Plan shall prevail.

     If designated in the Notice of Grant as an Incentive Stock Option ("ISO"),
this Option is intended to qualify as an ISO under Section 422 of the
Code. However, if this Option is intended to be an ISO, to the extent that it
exceeds the $100,000 rule of Section 422(d), that portion which exceeds the
$100,000 limit shall be treated as a nonstatutory stock option ("NSO") under
Section 422. See the Plan Summary and Prospectus for additional information
regarding ISOs and NSOs.

2.   Exercise of Option.

     (a) Vesting Schedule. Subject to the limitations contained herein and in
     the Plan, this Option shall be exercisable according to the following
     vesting schedule.

          25% of the Shares subject to each Option Grant shall vest on each
          anniversary of the vesting start date for the Grant as provided in
          the Grant Notice. Prior to vesting, the Shares available to Optionee
          shall be unvested. In no event shall any additional shares vest after
          Optionee's cessation of Service except as provided herein.

     (b) Right to Exercise. This Option is exercisable during its term in
     accordance with the Vesting Schedule set forth above and the other
     applicable provisions of this Option Grant Agreement and the Plan,
     including the provisions applicable in the event of the Optionee's death,
     disability or termination of employment or consulting relationship.

     (c) Minimum Number of Shares. The minimum number of shares with respect to
     which this Option may be exercised at any one time is the lesser of (a)
     fifty (50) Shares or (b) the number of Shares that have vested in the
     preceding six (6) month period prior to the exercise.

     (d) Method of Exercise. This Option is exercisable by delivery of an
     exercise notice, in a form designated by the Corporation and attached
     hereto as Exhibit A ("the Exercise Notice"), which shall state the
     election to exercise the Option, the number of Shares in respect of which
     the Option is being exercised (the "Exercised Shares"), and such other
     representations and agreements as may be required by the Corporation
     pursuant to the provisions of the Plan. The Exercise


                                       1
<PAGE>   15

     Notice shall be signed by the Optionee and shall be delivered in person or
     by certified mail to the Stock Administrator of the Corporation. The
     Exercise Notice shall be accompanied by payment (in any of the manners set
     forth in Section 3 below) of the aggregate Exercise Price as to all
     Exercised Shares. This Option shall only be deemed to be exercised upon
     receipt by the Corporation of such fully executed Exercise Notice
     accompanied by such aggregate Exercise Price.

     (e)  Issuance of Shares.  No Shares shall be issued pursuant to the
     exercise of this Option unless such issuance and exercise complies with all
     relevant provisions of law and the requirements of any stock exchange or
     quotation service upon which the Shares are then listed. Assuming such
     compliance, for income tax purposes the Exercised Shares shall be
     considered transferred to the Optionee on the date the Option is exercised
     with respect to such Exercised Shares.

3.   Method of Payment.  Payment of the aggregate Exercise Price shall be by
any of the following, or a combination thereof, at the election of the Optionee:

     (a)  cash; or

     (b)  check; or

     (c)  delivery of a properly executed Exercise Notice together with each
          other documentation as the Administrator and the broker, if
          applicable, shall require to effect an exercise of the Option and
          delivery to the Corporation of the sale or loan proceeds required to
          pay the exercise price; or

     (d)  surrender of other Shares that (i) in the case of Shares acquired upon
          exercise of an Option, have been owned by the Optionee more than six
          (6) months on the date of surrender, and (ii) have a Fair Market Value
          on the date of surrender equal to the aggregate Exercise Price of the
          Exercised Shares.

4.   Non-transferability of Option.  This Option may not be transferred in any
manner otherwise than by will or by the laws of descent or distribution and may
be exercised during the lifetime of Optionee only by the Optionee. The terms of
the Plan and this Agreement shall be binding upon the executors, administrators,
heirs, successors and assigns of the Optionee.

5.   Optionee's Representations.   In the event that the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this
option is exercised, the Optionee shall, if required by the Company,
concurrently with the exercise of all or any portion of this Option, deliver to
the Company his or her Investment Representation statement in the form attached
hereto as Exhibit B. Optionee agree to read all applicable rules of the
Commissioner of Corporations attached to such Investment Representations
Statement.

6.   Lock-Up Period.  Optionee hereby agrees that, if so requested by the
Company or any representative of the underwriters ("the Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180 day period (or such
other period as may be requested by the Managing Underwriter and agreed to in
writing by the Company) (the "Market Standoff Period") following the effective
date of a registration statement of the

                                       2
<PAGE>   16
Company filed under the Securities Act. Such restriction shall apply only to the
first registration statement of the Company to become effective under the
Securities Act that includes securities to be sold on behalf of the Company to
the public in an underwritten public offering under the Securities Act. The
Company may impose stop-transfer instructions with respect to securities subject
to the foregoing restrictions until the end of such Market Standoff Period.

7.   Restriction on Exercise. This Option may not be exercised until such time
as the Plan has been approved by the shareholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
law.

8.   Non-transferability of Option. This Option may not be transferred in any
manner other than by will or by the laws of descent or distribution and may be
exercised during the lifetime of Optionee only by Optionee. The terms of the
Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

9.   Term of Option. The term of this Option commences on the date of the grant
and, unless sooner terminated as set forth below or in the Plan, terminates on
the date that is seven (7) years later. Upon termination of the Optionee's
employment with the Corporation, this Option may be exercised only as to that
number of shares as to which it was exercisable on the date of termination and
only for a period of sixty (60) days thereafter (but not later than the term of
this Option set forth above) and shall then terminate. Upon the death or
disability of the Optionee, however, this Option may be exercised for such
longer period as provided in the Plan.

10.  No Guarantee of Continued Service. OPTIONEE ACKNOWLEDGES AND AGREES THAT
THE VESTING OF THE SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY
BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH THE
ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER).
OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT
CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE
PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT
INTERFERE IN ANY WAY WITH THE OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE.

11.  Tax Consequences. Set forth below is a brief summary as of the date of this
Option of some of the federal tax consequences of exercise of this Option and
disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX
LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. THE OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

     (a) Exercise of ISO. If this Option qualifies as an ISO, there will be no
         regular federal income tax liability upon exercise of the Option,
         although the

                                       3
<PAGE>   17
         excess, if any of the Fair Market Value of the Shares on the date of
         exercise over the Exercise Price will be treated as an adjustment to
         the alternative minimum tax for federal tax purposes and may subject
         the Optionee to the alternative minimum tax in the year of exercise.

     (b) Exercise of NSO. There may be a regular federal income tax liability
         upon the exercise of an NSO. The Optionee will be treated as having
         received compensation income (taxable at ordinary income tax rates)
         equal to the excess, if any, of the Fair Market Value of the Shares on
         the date of exercise over the Exercise Price. If Optionee is an
         Employee or a former Employee, the Company will be required to withhold
         from Optionee's compensation or collect from Optionee and pay to the
         applicable taxing authorities an amount in cash equal to a percentage
         of this compensation income at the time of exercise, and may refuse to
         honor the exercise and refuse to deliver the Shares if such withholding
         amounts are not delivered at the time of exercise.

     (c) Disposition of Shares. In the case of an NSO, if Shares are held for at
         least one year, any gain realized on disposition of the Shares will be
         treated as long-term capital gain for federal income tax purposes. In
         the case of an ISO, if Shares transferred pursuant to the Option are
         held for at least one year after exercise and at least two years after
         the Date of Grant, any gain realized on the disposition of the Shares
         will be also treated as long-term capital gain for federal income tax
         purposes. If Shares purchased under an ISO are disposed of within one
         year after exercise or two years after the Date of Grant, any gain
         realized on such dispositions will be treated as compensation income
         (taxable at ordinary income rates) to the extent of the difference
         between the Exercise Price and the lesser of (1) the Fair Market Value
         of the Shares on the date of exercise, or (2) the sale price of the
         Shares. Any additional gain will be taxed as capital gain, short-term
         or long-term depending on the period that the ISO shares were held.

     (d) Notice of Disqualifying Disposition of ISO Shares. If the Optionee
         sells or otherwise disposes of any of the Shares acquired pursuant to
         an ISO on or before the later of (i) two (2) years after the Vesting
         Start Date, or (ii) one (1) year after the exercise date, the Optionee
         shall immediately notify the Corporation in writing of such
         disposition. The Optionee agrees that he or she may be subject to
         income tax withholding by the Corporation on the compensation income
         recognized from such early disposition of the ISO Shares by payment in
         cash or out of the current earnings paid to the Optionee.

12.  Entire Agreement; Governing Law. The Plan is incorporated herein by
reference. The Plan and this Option Agreement constitute the entire agreement of
the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and the Optionee
with respect to the subject matter hereof, and may not be modified adversely to
the Optionee's interest except by means of a writing signed by the Company and
Optionee. This agreement is governed by the internal substantive laws but not
the choice of law rules of California.

     Optionee acknowledges receipt of a copy of the Plan and represents that he
or she is familiar with the terms and provisions thereof, and hereby accepts
this Option subject to all of the terms and provisions thereof. Optionee has
reviewed the Plan and this Option


                                       4
<PAGE>   18
in their entirety, has had an opportunity to obtain the advice of counsel prior
to executing this Option and fully understands all provisions of the Option.
Optionee hereby agrees to accept as binding, conclusive and final all decisions
or interpretations of the Administrator upon any questions arising under the
Plan or this Option. Optionee further agrees to notify the Company upon any
change in the residence address listed below.

              BACKWEB TECHNOLOGIES, LTD. 1998 US STOCK OPTION PLAN

                                EXERCISE NOTICE

BackWeb Technologies, Ltd.
2077 Gateway Place, Suite 500
San Jose, CA 95110

Attention: Stock Plan Administrator

     1.   Exercise of Option. Effective as of today, ______, 19__, the
undersigned ("Optionee") hereby elects to exercise Optionee's option to
purchase _______ Ordinary Shares (the "Shares") of BackWeb Technologies, Inc.
(the "Corporation") under and pursuant to the 1998 US Stock Option Plan (the
"Plan") and the related Stock Option Agreement (the "Agreement").

     2.   Delivery of Payment. Purchaser herewith delivers to the Corporation
the full purchase price of the Shares, as set forth in the Agreement.

     3.   Representations of Optionee. Optionee acknowledges that Optionee has
received, read and understood the Plan and the Agreement and agrees to abide by
and be bound by their terms and conditions.

     4.   Rights as Shareholder. Until the issuance of the Shares (as evidenced
by the appropriate entry on the books of the Corporation or of a duly
authorized transfer agent of the Corporation), no right to vote or receive
dividends or any other rights as a shareholder shall exist with respect to the
Optioned Stock, notwithstanding the exercise of the Option. The Shares shall be
issued to the Optionee as soon as practicable after the Option is exercised. No
adjustment shall be made for a dividend or other right for which the record
date is prior to the date of issuance.

     5.   Corporation's Right of First Refusal. Before any Shares held by
Optionee or any transferee (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Corporation or its assignee(s) shall have a right of
first refusal to purchase the Shares on the terms and conditions set forth
below in this Section:

          (a)  Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Corporation a written notice (the "Notice") stating: (i) the
Holder's bona fide intention to sell or otherwise transfer such Shares; (ii)
the name of each proposed purchaser or other transferee ("Proposed
Transferee"); (iii) the number of Shares to be transferred to each Proposed
Transferee; and (iv) the bona fide cash price or other consideration for which
the Holder proposes to transfer the Shares (the "Offered Price"), and the
Holder shall offer the Shares at the Offered Price to the Corporation or its
assignee(s).


                                       6
<PAGE>   20
          (b)  Exercise of Right of First Refusal. At any time within thirty
(30) days after receipt of the Notice, the Corporation and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not
less than all, of the Shares proposed to be transferred to any one or more of
the Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

          (c)  Purchase Price. The purchase price ("Purchase Price") for the
Shares purchased by the Corporation or its assignee(s) under this Section shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Corporation in good faith.

          (d)  Payment. Payment of the Purchase Price shall be made, at the
option of the Corporation or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Corporation (or, in the case of repurchase by an assignee, to the
assignee), or by any combination thereof within 30 days after receipt of the
Notice or in the manner and at the times set forth in the Notice.

          (e)  Holder's Right to Transfer. If all of the Shares proposed in the
Notice to be transferred to a given Proposed Transferee are not purchased by
the Corporation and/or its assignee(s) as provided in this Section, then the
Holder may sell or otherwise transfer such Shares to that Proposed Transferee
at the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 120 days after the date of the Notice, that
any such sale or other transfer is effected in accordance with any applicable
securities laws and that the Proposed Transferee agrees in writing that
the provisions of this Section shall continue to apply to the Shares in the
hands of such Proposed Transferee. If the Shares described in the Notice are
not transferred to the Proposed Transferee within such period, a new Notice
shall be given to the Corporation, and the Corporation and/or its assignees
shall again be offered the Right of First Refusal before any Shares held by the
Holder may be sold or otherwise transferred.

          (f)  Exception for Certain Family Transfers. Anything to the contrary
contained in this Section notwithstanding, the transfer of any or all of the
Shares during the Optionee's lifetime or on the Optionee's death by will or
intestacy to the Optionee's immediate family or a trust for the benefit of the
Optionee's immediate family shall be exempt from the provisions of this Section.
"Immediate Family" as used herein shall mean spouse, lineal descendant or
antecedent, father, mother, brother or sister. In such case, the transferee or
other recipient shall receive and hold the Shares so transferred subject to the
provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

          (g)  Termination of Right of First Refusal. The Right of First
Refusal shall terminate as to any Shares upon the first sale of Common Stock of
the Corporation to the general public pursuant to a registration statement
filed with and declared effective by the Securities and Exchange Commission
under the Securities Act of 1933, as amended.

        6.      Tax Consultation.  Optionee understands that Optionee may
suffer adverse tax consequences as a result of Optionee's purchase or
disposition of the Shares. Optionee represents that Optionee has consulted with
any tax consultants Optionee deems advisable in connection with the purchase or
disposition of the Shares and that Optionee is not relying on the Corporation
for any tax advice.

        7.      Restrictive Legends and Stop-Transfer Orders

                (a)     Legends.  Optionee understands and agrees that the
Corporation shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership
of the Shares together with any other legends that may be required by the
Corporation or by state or federal securities laws:

                THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE
                OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED
                UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF
                COMPANY COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES,
                SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN
                COMPLIANCE THEREWITH.

                THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                CERTAIN RESTRICTIONS ON TRANSFER AND RIGHT TO FIRST REFUSAL
                OPTIONS HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN
                THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER
                OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE
                PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND
                RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE
                SHARES.

                IT IS UNLAWFUL TO CONSUMMATE A SALE OR TRANSFER OF THIS
                SECURITY, OR ANY INTEREST THEREIN, OR TO RECEIVE ANY
                CONSIDERATION THEREFOR, WITHOUT THE PRIOR WRITTEN CONSENT OF THE
                COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA, EXCEPT
                AS PERMITTED IN THE COMMISSIONER'S RULES.

                Optionee understands that transfer of the Shares may be
restricted by Section 260.141.11 of the Rules of the California Corporations
Commissioner, a copy of which is attached as the Investment Representation
Statement.

                (b)     Stop-Transfer Notices.  Optionee agrees that, in order
to ensure compliance with the restrictions referred to herein, the Corporation
may issue appropriate "stop transfer" instructions to its transfer agent, if
any, and that, if the Corporation transfers its own securities, it may make
appropriate notations to the same effect in its own records.

                (c)     Refusal to Transfer.  The Corporation shall not be
required (i) to transfer on its books any Shares that have been sold or
otherwise transferred in violation of any of the provisions of this Agreement
or (ii) to treat as owner of such Shares or to accord the right to vote or pay
dividends to any purchaser or other transferee to whom such Shares shall have
been so transferred.

        8.      Successors and Assigns.  The Corporation may assign any of its
rights under this Agreement to single or multiple assignees, and this Agreement
shall inure to the benefit of the successors and assigns of the Corporation.
Subject to the restrictions on transfer herein set forth, this Agreement shall
be binding upon Optionee and his or her heirs, executors, administrators,
successors and assigns.

        9.      Interpretation.  Any dispute regarding the interpretation of
this Agreement shall be submitted by Optionee or by the Corporation forthwith
to the Administrator which shall review such dispute at its next regular
meeting. The resolution of such a dispute by the Administrator shall be final
and binding on all parties.

        10.     Governing Law; Severability.  This Agreement is governed by the
internal substantive laws, but not the choice of law rules, of California.

        11.     Entire Agreement.  The Plan and Agreement are incorporated
herein by reference. This Agreement, the Plan, the Restricted Stock Purchase
Agreement, the Agreement and the Investment Representation Statement constitute
the entire agreement of the parties with respect to the subject matter hereof
and supersede in their entirety all prior undertakings and agreements of the
Corporation and Optionee with respect to the subject matter hereof, and may not
be modified adversely to the Optionee's interest except by means of a writing
signed by the Corporation and Optionee.

                                   EXHIBIT B

                      INVESTMENT REPRESENTATION STATEMENT

OPTIONEE    :  ____________________________

COMPANY     :  BackWeb Technologies, Ltd.

SECURITY    :  Ordinary Shares of Common Stock

AMOUNT      :  As provided in the attached Exercise Notice

DATE        :

In connection with the purchase of the above-listed Securities, the undersigned
Optionee represents to the Company the following:

     (a)  Optionee is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities. Optionee is
acquiring these Securities for investment for Optionee's own account only and
not with a view to, or for resale in connection with, any "distribution"
thereof within the meaning of the Securities Act of 1933, as amended (the
"Securities Act").

     (b)  Optionee acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Optionee's
investment intent as expressed herein. In this connection, Optionee understands
that, in the view of the Securities and Exchange Commission, the statutory
basis for such exemption may be unavailable if Optionee's representation was
predicated solely upon a present intention to hold these Securities for the
minimum capital gains period specified under tax statutes, for a deferred
sale, for or until an increase or decrease in the market price of the
Securities, or for a period of one year or any other fixed period in the
future. Optionee further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act
or an exemption from such registration is available. Optionee further
acknowledges and understands that the Company is under no obligation to
register the Securities. Optionee understands that the certificate evidencing
the Securities will be imprinted with a legend which prohibits the transfer of
the Securities unless they are registered or such registration is not required
in the opinion of counsel satisfactory to the Company, a legend prohibiting
their transfer without the consent of the Commissioner of Corporations of the
State of [state] and any other legend required under applicable state securities
laws.

     (c)  Optionee is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions. Rule 701 provides

                                       10

<PAGE>   24
that if the issuer qualifies under Rule 701 at the time of the grant of the
Option to the Optionee, the exercise will be exempt from registration under the
Securities Act. In the event the Company becomes subject to the reporting
requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934,
ninety (90) days thereafter (or such longer period as any market stand-off
agreement may require) the Securities exempt under Rule 701 may be resold,
subject to the satisfaction of certain of the conditions specified by Rule 144,
including: (1) the resale being made through a broker in an unsolicited
"broker's transaction" or in transactions directly with a market maker (as said
term is defined under the Securities Exchange Act of 1934); and, in the case of
an affiliate, (2) the availability of certain public information about the
Company, (3) the amount of Securities being sold during any three month period
not exceeding the limitations specified in Rule 144(e), and (4) the timely
filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than two years after the later of the date the Securities
were sold by the Company or the date the Securities were sold by an affiliate of
the Company, within the meaning of Rule 144; and, in the case of acquisition of
the Securities by an affiliate, or by a non-affiliate who subsequently holds
the Securities less than three years, the satisfaction of the conditions set
forth in sections (1), (2), (3) and (4) of the paragraph immediately above.

          (d)  Optionee further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that
an exemption from registration is available for such offers or sales, and that
such persons and their respective brokers who participate in such transactions
do so at their own risk. Optionee understands that no assurances can be given
that any such other registration exemption will be available in such event.

          (e)  Optionee understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities without the consent of the Commissioner of Corporations of
California. Optionee has read the applicable Commissioner's Rules with respect
to such restriction, a copy of which is attached.

                                  Signature of Optionee: ______________________

     securities is not in violation of any securities law of the foreign state,
     territory or country concerned.

     transaction, or as an underwriter or member of an underwriting syndicate or

          (9)  if the interest sold or transferred is a pledge or other lien
     given by the purchaser to the seller upon a sale of the security for which
     the Commissioner's written consent is obtained or under this rule is not
     required;

          (10) by way of a sale qualified under Sections 25111, 25112, 25113 or

     either such case, such person (i) discloses to potential purchasers at the
     sale that transfer of the securities is restricted under this rule, (ii)
     delivers to each purchaser a copy of this rule, and (iii) advises the
     Commissioner of the name of each purchaser;

          (16) by a trustee to a successor trustee when such transfer does not
     involve a change in the beneficial ownership of the securities;

        1. Purpose. The purpose of the Plan is to provide employees of the
Company and its Designated Subsidiaries with an opportunity to purchase Ordinary

        4. Offering Periods. The Plan shall be implemented by consecutive
Offering Periods with a new Offering Period commencing on the first Trading Day
on or after March 1 and September 1 each year, or on such other date as the
Board shall determine, and continuing thereafter until terminated in accordance
with Section 20 hereof; provided, however, that the first Offering Period under
the Plan shall commence with the first Trading Day on or after the date on which
the Securities and Exchange Commission declares the Company's Registration
Statement effective and ending on the last Trading Day on or before February 29,
2000. The Board shall have the power to change the duration of Offering Periods
(including the commencement dates thereof) with respect to future offerings
without stockholder approval if such change is announced at least five (5) days

completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office prior
to the applicable Enrollment Date.

                (b) Payroll deductions for a participant shall commence on the
first payroll following the Enrollment Date and shall end on the last payroll in
the Offering Period to which such



                                      -3-
<PAGE>   4

authorization is applicable, unless sooner terminated by the participant as
provided in Section 10 hereof.

        6. Payroll Deductions.

                (a) At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding fifteen percent (15%) of
the Compensation which he or she receives on each pay day during the Offering
Period. Such deduction shall be a whole percentage of the participant's
Compensation, but not less than 1% nor more than 15%.

                (b) All payroll deductions made for a participant shall be
credited to his or her account under the Plan and shall be withheld in whole
percentages only. A participant may not make any additional payments into such
account.

                (c) A participant may discontinue his or her participation in
the Plan as provided in Section 10 hereof, or may increase or decrease the rate
of his or her payroll deductions during the Offering Period by completing or
filing with the Company a new subscription agreement authorizing a change in
payroll deduction rate. A participant shall make no more than one election to
make a participation rate change per quarter. The Board may, in its discretion,
further limit or expand the number of participation rate changes during any
Offering Period. The change in rate shall be effective with the first full
payroll period following five (5) business days after the Company's receipt of
the new subscription agreement unless the Company elects to process a given
change in participation more quickly. A participant's subscription agreement
shall remain in effect for successive Offering Periods unless terminated as
provided in Section 10 hereof.

                (d) Notwithstanding the foregoing, to the extent necessary to
comply with Section 423(b)(8) of the Code and Section 3(b) hereof, a
participant's payroll deductions may be decreased to zero percent (0%) at any
time during an Offering Period. Payroll deductions shall recommence at the rate
provided in such participant's subscription agreement at the beginning of the
first Offering Period which is scheduled to end in the following calendar year,
unless terminated by the participant as provided in Section 10 hereof.

                (e) At the time the option is exercised, in whole or in part, or
at the time some or all of the Company's Ordinary Shares issued under the Plan
are disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Ordinary Shares. At any
time, the Company may, but shall not be obligated to, withhold from the
participant's compensation the amount necessary for the Company to meet
applicable withholding obligations, including any withholding required to make
available to the Company any tax deductions or benefits attributable to sale or
early disposition of Ordinary Shares by the Employee.

        7. Grant of Option. On the Enrollment Date of each Offering Period, each
eligible Employee participating in such Offering Period shall be granted an
option to purchase on the



                                      -4-
<PAGE>   5

Exercise Date of such Offering Period (at the applicable Purchase Price) up to a
number of the Company's Ordinary Shares determined by dividing such Employee's
payroll deductions accumulated prior to such Exercise Date and retained in the
Participant's account as of the Exercise Date by the applicable Purchase Price;
provided that in no event shall an Employee be permitted to purchase during each
Offering Period more than 10,000 shares (subject to any adjustment pursuant to
Section 19), and provided further that such purchase shall be subject to the
limitations set forth in Sections 3(b) and 12 hereof. Exercise of the option
shall occur as provided in Section 8 hereof, unless the participant has
withdrawn pursuant to Section 10 hereof. The Option shall expire on the last day
of the Offering Period.

        8. Exercise of Option. Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Offering Period, subject to earlier withdrawal by the participant as provided in
Section 10 hereof. Any other monies left over in a participant's account after
the Exercise Date shall be returned to the participant. During a participant's
lifetime, a participant's option to purchase shares hereunder is exercisable
only by him or her.

        9. Delivery. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, the shares purchased upon exercise of his or
her option.

        10. Withdrawal.

                (a) A participant may withdraw all but not less than all the
payroll deductions credited to his or her account and not yet used to exercise
his or her option under the Plan at any time by giving written notice to the
Company in the form of Exhibit B to this Plan. All of the participant's payroll
deductions credited to his or her account shall be paid to such participant
promptly after receipt of notice of withdrawal and such participant's option for
the Offering Period shall be automatically terminated, and no further payroll
deductions for the purchase of shares shall be made for such Offering Period. If
a participant withdraws from an Offering Period, payroll deductions shall not
resume at the beginning of the succeeding Offering Period unless the participant
delivers to the Company a new subscription agreement.

                (b) A participant's withdrawal from an Offering Period shall not
have any effect upon his or her eligibility to participate in any similar plan
which may hereafter be adopted by the Company or in succeeding Offering Periods
which commence after the termination of the Offering Period from which the
participant withdraws.

        11. Termination of Employment. Upon a participant's ceasing to be an
Employee for any reason, he or she shall be deemed to have elected to withdraw
from the Plan and the payroll



                                      -5-
<PAGE>   6

deductions credited to such participant's account during the Offering Period but
not yet used to exercise the option shall be returned to such participant or, in
the case of his or her death, to the person or persons entitled thereto under
Section 15 hereof, and such participant's option shall be automatically
terminated. The preceding sentence notwithstanding, a participant who receives
payment in lieu of notice of termination of employment shall be treated as
continuing to be an Employee for the participant's customary number of hours per
week of employment during the period in which the participant is subject to such
payment in lieu of notice.

        12. Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

        13. Stock.

                (a) Subject to adjustment upon changes in capitalization of the
Company as provided in Section 19 hereof, the maximum number of the Company's
Ordinary Shares which shall be made available for sale under the Plan shall be
1,800,000 shares, plus an annual increase to be added on July 1st of each year
beginning in 2000 equal to the lesser of (i) 2,500,000 shares, (ii) 2% of the
outstanding shares on such date or (iii) an amount determined by the Board. If,
on a given Exercise Date, the number of shares with respect to which options are
to be exercised exceeds the number of shares then available under the Plan, the
Company shall make a pro rata allocation of the shares remaining available for
purchase in as uniform a manner as shall be practicable and as it shall
determine to be equitable.

                (b) The participant shall have no interest or voting right in
shares covered by his option until such option has been exercised.

                (c) Shares to be delivered to a participant under the Plan shall
be registered in the name of the participant or in the name of the participant
and his or her spouse.

        14. Administration. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

        15. Designation of Beneficiary.

                (a) A participant may file a written designation of a
beneficiary who is to receive any shares and cash, if any, from the
participant's account under the Plan in the event of such participant's death
subsequent to an Exercise Date on which the option is exercised but prior to
delivery to such participant of such shares and cash. In addition, a participant
may file a written designation of a beneficiary who is to receive any cash from
the participant's account under the Plan in the event of such participant's
death prior to exercise of the option. If a participant is married and the



                                      -6-
<PAGE>   7

designated beneficiary is not the spouse, spousal consent shall be required for
such designation to be effective.

                (b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

        16. Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

        17. Use of Funds. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

        18. Reports. Individual accounts shall be maintained for each
participant in the Plan. Statements of account shall be given to participating
Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

        19. Adjustments Upon Changes in Capitalization, Dissolution,
Liquidation, Merger or Asset Sale.

                (a) Changes in Capitalization. Subject to any required action by
the stockholders of the Company, the Reserves, the maximum number of shares each
participant may purchase per Offering Period (pursuant to Section 7), as well as
the price per share and the number of shares of Ordinary Shares covered by each
option under the Plan which has not yet been exercised shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Ordinary
Shares resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Ordinary Shares, or any other increase or
decrease in the number of shares of Ordinary Shares effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration". Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of



                                      -7-
<PAGE>   8

stock of any class, shall affect, and no adjustment by reason thereof shall be
made with respect to, the number or price of shares of Ordinary Shares subject
to an option.

                (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the Board. The New
Exercise Date shall be before the date of the Company's proposed dissolution or
liquidation. The Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
the participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

                (c) Merger or Asset Sale. In the event of a proposed sale of all
or substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation or a parent or
Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the option, the Offering Period
then in progress shall be shortened by setting a new Exercise Date (the "New
Exercise Date"). The New Exercise Date shall be before the date of the Company's
proposed sale or merger. The Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the participant's option has been changed to the New Exercise Date and
that the participant's option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

        20. Amendment or Termination.

                (a) The Board of Directors of the Company may at any time and
for any reason terminate or amend the Plan. Except as provided in Section 19
hereof, no such termination can affect options previously granted, provided that
an Offering Period may be terminated by the Board of Directors on any Exercise
Date if the Board determines that the termination of the Offering Period or the
Plan is in the best interests of the Company and its stockholders. Except as
provided in Section 19 and Section 20 hereof, no amendment may make any change
in any option theretofore granted which adversely affects the rights of any
participant. To the extent necessary to comply with Section 423 of the Code (or
any other applicable law, regulation or stock exchange rule), the Company shall
obtain shareholder approval in such a manner and to such a degree as required.

                (b) Without stockholder consent and without regard to whether
any participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly



                                      -8-
<PAGE>   9

completed withholding elections, establish reasonable waiting and adjustment
periods and/or accounting and crediting procedures to ensure that amounts
applied toward the purchase of Ordinary Shares for each participant properly
correspond with amounts withheld from the participant's Compensation, and
establish such other limitations or procedures as the Board (or its committee)
determines in its sole discretion advisable which are consistent with the Plan.

                (c) In the event the Board determines that the ongoing operation
of the Plan may result in unfavorable financial accounting consequences, the
Board may, in its discretion and, to the extent necessary or desirable, modify
or amend the Plan to reduce or eliminate such accounting consequence including,
but not limited to:

                        (1) altering the Purchase Price for any Offering Period
including an Offering Period underway at the time of the change in Purchase
Price;

                        (2) shortening any Offering Period so that Offering
Period ends on a new Exercise Date, including an Offering Period underway at the
time of the Board action; and

                        (3) allocating shares.

                Such modifications or amendments shall not require stockholder
approval or the consent of any Plan participants.

        21. Notices. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

        22. Conditions Upon Issuance of Shares. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

        As a condition to the exercise of an option, the Company may require the
person exercising such option to represent and warrant at the time of any such
exercise that the shares are being purchased only for investment and without any
present intention to sell or distribute such shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law.

        23. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 20 hereof.

                                     LEASE

THIS LEASE is made as of the 23rd day of December, 1998, by and between Spieker
Properties, L.P., a California limited partnership (hereinafter called
"LANDLORD"), and BackWeb Technologies, Inc., a Delaware corporation
(hereinafter called "TENANT").

                                 1.   PREMISES

     Landlord leases to Tenant and Tenant leases from Landlord, upon the terms
and conditions hereinafter set forth, those premises (the "PREMISES") outlined
in red on EXHIBIT B and described in the Basic Lease Information. The Premises
shall be all or part of a building (the "BUILDING") and of a project (the
"PROJECT"), which may consist of more than one building and additional
facilities, as described in the Basic Lease Information. The Building and
Project are outlined in blue and green respectively on EXHIBIT B. Landlord and
Tenant acknowledge that physical changes may occur from time to time in the
Premises, Building or Project, and that the number of buildings and additional
facilities which constitute the Project may change from time to time, which may
result in an adjustment in Tenant's Proportionate Share, as defined in the Basic
Lease Information, as provided in Paragraph 7.A.

                      2.  POSSESSION AND LEASE COMMENCEMENT

A.   EXISTING IMPROVEMENTS.  If this Lease pertains to a Premises in which the
interior improvements have already been constructed ("EXISTING IMPROVEMENTS"),
the provisions of this Paragraph 2.A. shall apply and the term commencement date
("TERM COMMENCEMENT DATE") shall be the earlier of the date on which: (1) Tenant
takes possession of some or all of the Premises; or (2) Landlord notifies Tenant
that Tenant may occupy the Premises. If for any reason Landlord cannot deliver
possession of the Premises to Tenant on the scheduled Term Commencement Date,
Landlord shall not be subject to any liability therefor, nor shall Landlord be
in default hereunder nor shall such failure affect the validity of this Lease,
and Tenant agrees to accept possession of the Premises at such time as Landlord
is able to deliver the same, which date shall then deemed the Term Commencement
Date. Tenant shall not be liable for any Rent (defined below) for any period
prior to the Term Commencement Date. Tenant acknowledges that Tenant has
inspected and accepts the Premises in their present condition, "as is," and as
suitable for, the Permitted Use (as defined below), and for Tenant's intended
operations in the Premises. Tenant agrees that the Premises and other
improvements are in good and satisfactory condition as of when possession was
taken. Tenant further acknowledges that no representations as to the condition
or repair of the Premises nor promises to alter, remodel or improve the Premises
have been made by Landlord or any agents of Landlord unless such are expressly
set forth in this Lease. Upon Landlord's request, Tenant shall promptly execute
and return to Landlord a "Start-Up Letter" in which Tenant shall agree, among
other things, to acceptance of the Premises and to the determination of the Term
Commencement Date, in accordance with the terms of this Lease, but Tenant's
failure or refusal to do so shall not negate Tenant's acceptance of the Premises
or affect determination of the Term Commencement Date.

B.   CONSTRUCTION OF IMPROVEMENTS.  If this Lease pertains to a Building to be
constructed or improvements to be constructed within a Building, the provisions
of this Paragraph 2.B. shall apply in lieu of the provisions of Paragraph 2.A.
above and the term commencement date ("TERM COMMENCEMENT DATE") shall be the
earlier of the date on which: (1) Tenant takes possession of some or all of the
Premises; or (2) the improvements to be constructed or performed in the Premises
by Landlord (if any) shall have been substantially completed in accordance with
the plans and specifications, if any, described on EXHIBIT C and Tenant's taking
of possession of the Premises or any part thereof shall constitute Tenant's
confirmation of substantial completion for all purposes hereof, whether or not
substantial completion of the Building or Project shall have occurred. If for
any reason Landlord cannot deliver possession of the Premises to Tenant on the
scheduled Term Commencement Date, Landlord shall not be subject to any liability
therefor, nor shall Landlord be in default hereunder nor shall such failure
affect the validity of this Lease, and Tenant agrees to accept possession of the
Premises at such time as such improvements have been substantially completed,
which date shall then be deemed the Term Commencement Date. Tenant shall not be
liable for any Rent for any period prior to the Term Commencement Date (but
without affecting any obligations of Tenant under any improvement agreement
appended to this Lease). In the event of any dispute as to substantial
completion of work performed or required to be performed by Landlord, the
certificate of Landlord's architect or general contractor shall be conclusive.
Substantial completion shall have occurred notwithstanding Tenant's submission
of a punchlist to Landlord, which Tenant shall submit, if at all, within three
(3) business days after the Term Commencement Date or otherwise in accordance
with any improvement agreement appended to this Lease. Upon Landlord's request,
Tenant shall promptly execute and return to Landlord a "Start-Up Letter" in
which Tenant shall agree, among other things, to acceptance of the Premises and
to the determination of the Term Commencement Date, in accordance with the terms
of this Lease, but Tenant's failure to refusal to do so shall not negate
Tenant's acceptance of the Premises or affect determination of the Term
Commencement Date.

                                    3.  TERM

     The term of this Lease (the "TERM") shall commence on the Term Commencement
Date and continue in full force and effect for the number of months specified
as the Length of Term in the Basic Lease Information or until this Lease is
terminated as otherwise provided herein. If the Term Commencement Date is a date
other than the first day of the calendar month, the Term shall be the number of
months of the Length of Term in addition to the remainder of the calendar month
following the Term Commencement Date.

                                    4.  USE

A.   GENERAL.  Tenant shall use the Premises for the permitted use specified in
the Basic Lease Information ("PERMITTED USE") and for no other use or purpose.
Tenant shall control Tenant's employees, agents, customers, visitors, invitees,
licensees, contractors, assignees and subtenants (collectively, "TENANT'S
PARTIES") in such a manner that Tenant and Tenant's Parties cumulatively do not
exceed the occupant density (the "OCCUPANCY DENSITY") or the parking density
(the "PARKING DENSITY") specified in the Basic Lease Information at any time. So
long as Tenant is occupying the Premises, Tenant and Tenant's Parties shall have
the nonexclusive right to use, in common with other parties occupying the
Building or Project, the parking areas, driveways and other common areas of the
Building and Project, subject to the terms of this Lease and such rules and
regulations as Landlord may from time to time prescribe. Landlord reserves the
right, without notice or liability to Tenant, and without the same constituting
an actual or constructive eviction, to alter or modify the common areas from
time to time, including the location and configuration thereof, and the
amenities and facilities which Landlord may determine to provide from time to
time.

B.   LIMITATIONS. Tenant shall not permit any odors, smoke, dust, gas,
substances, noise or vibrations to emanate from the Premises or from any portion
of the common areas as a result of Tenant's or any Tenant's Party's use thereof,
nor take any action which would constitute a nuisance or would disturbed,
obstruct or endanger any other tenants or occupants of the Building or Project
or elsewhere, or interfere with their use of their respective premises or common
areas. Storage outside the Premises of materials, vehicles or any other


                                       3
<PAGE>   4
items is prohibited. Tenant shall not use or allow the Premises to be used for
any immoral, improper or unlawful purpose, nor shall Tenant cause or maintain
or permit any nuisance in, on or about the Premises. Tenant shall not commit or
suffer the commission of any waste in, on or about the Premises. Tenant shall
not allow any sale by auction upon the Premises, or place any loads upon the
floors, walls or ceilings which could endanger the structure, or place any
harmful substances in the drainage system of the Building or Project. No waste,
materials or refuse shall be dumped upon or permitted to remain outside the
Premises. Landlord shall not be responsible to Tenant for the non-compliance by
any other tenant or occupant of the Building or Project with any of the
above-referenced rules or any other terms or provisions of such tenant's
occupant's lease or other contract.

C.   COMPLIANCE WITH REGULATIONS. By entering the Premises, Tenant accepts the
Premises in the condition existing as of the date of such entry. Tenant shall
at its sole cost and expense strictly comply with all existing or future
applicable municipal, state and federal and other governmental statutes, rules,
requirements, regulations, laws and ordinances, including zoning ordinances and
regulations, and covenants, easements and restrictions of record governing and
relating to the use, occupancy or possession of the Premises, to Tenant's use of
the common areas, or to the use, storage, generation or disposal of Hazardous
Materials (hereinafter defined) (collectively "REGULATIONS"). Tenant shall at
its sole cost and expense obtain any and all licenses or permits necessary for
Tenant's use of the Premises. Tenant shall at its sole cost and expense
promptly comply with the requirements of any board of fire underwriters or
other similar body now or hereafter constituted. Tenant shall not do or permit
anything to be done in, on, under or about the Project or bring or keep
anything which will in any way increase the rate of any insurance upon the
Premises, Building or Project or upon any contents therein or cause a
cancellation of said insurance or otherwise affect said insurance in any
manner. Tenant shall indemnify, defend (by counsel reasonably acceptable to
Landlord), protect and hold Landlord harmless from and against any loss, cost,
expense, damage, attorneys' fees or liability arising out of the failure of
Tenant to comply with any Regulation. Tenant's obligations pursuant to the
foregoing indemnity shall survive the expiration or earlier termination of this
Lease.

D.   HAZARDOUS MATERIALS. As used in this Lease, "HAZARDOUS MATERIALS" shall
include, but not be limited to, hazardous, toxic and radioactive materials and
those substance defined as "hazardous substances," "hazardous materials,"
"hazardous wastes," "toxic substances," or other similar designations in any
Regulation. Tenant shall not cause, or allow any of Tenant's Parties to cause,
any Hazardous Materials to be handled, used, generated, stored, released or
disposed of in, on, under or about the Premises, the Building or the Project or
surrounding land or environment in violation of any Regulations. Tenant must
obtain Landlord's written consent prior to the introduction of any Hazardous
Materials onto the Project. Notwithstanding the foregoing, Tenant may handle,
store, use and dispose of products containing small quantities of Hazardous
Materials for "general office purposes" (such as toner for copiers) to the
extent customary and necessary for the Permitted Use of the Premises; provided
that Tenant shall always handle, store, use, and dispose of any such Hazardous
Materials in a safe and lawful manner and never allow such Hazardous Materials
to contaminate the Premises, Building, or Project or surrounding land or
environment. Tenant shall immediately notify Landlord in writing of any
Hazardous Materials' contamination of any portion of the Project of which Tenant
becomes aware, whether or not caused by Tenant. Landlord shall have the right at
all reasonable times to impact the Premises and to conduct tests and
investigations to determine whether Tenant is in compliance with the foregoing
provisions, the costs of all such inspections, tests and investigations to be
borne by Tenant if Landlord has reasonable grounds to believe that Tenant is in
violation of the foregoing provisions of this Paragraph 4.D. Tenant shall
indemnify, defend (by counsel reasonably acceptable to Landlord), protect and
hold Landlord harmless from and against any and all claims, liabilities, losses,
costs, loss of rents, liens, damages, injuries or expenses (including attorneys'
and consultants' fees and court costs), demands, causes of action, or judgments
directly or indirectly arising out of or related to the use, generation,
storage, release, or disposal of Hazardous Materials by Tenant or any of
Tenant's Parties, in, on, under or about the Premises, the Building or the
Project or surrounding land or environment, excluding Hazardous Materials
present prior to the date of this Lease Date, which indemnity shall include,
without limitation, damages for personal or bodily injury, property damage,
damage to the environment or natural resources occurring on or off the Premises,
losses attributable to diminution in value or adverse effects on marketability,
the cost of any investigation, monitoring, government oversight, repair,
removal, remediation, restoration, abatement, and disposal, and the preparation
of any closure or other required plans, whether such action is required or
necessary prior to or following the expiration or earlier termination of this
Lease. Neither the consent by Landlord to the use, generation, storage, release
or disposal of Hazardous Materials nor the strict compliance by Tenant with all
laws pertaining to Hazardous Materials shall excuse Tenant from Tenant's
obligation of indemnification pursuant to this Paragraph 4.D. Tenant's
obligations pursuant to the foregoing indemnity shall survive the expiration or
earlier termination of this Lease.

                            5. RULES AND REGULATIONS

     Tenant shall faithfully observe and comply with the building rules and
regulations attached hereto as EXHIBIT A and any other rules and regulations

prescribe in writing for the purpose of maintaining the proper care,

Building or Project. Tenant shall cause Tenant's Parties to comply with such
rules and regulations. Landlord shall not be responsible to Tenant for the
non-compliance by any other tenant or occupant of the Building or Project with
any of such rules and regulations, any other tenant's or occupant's lease or
any Regulations.

Proportionate Share of the Building or Project to reflect the change.
Landlord's determination of Tenant's Proportionate Share of the Building and of
the Project shall be conclusive so long as it is reasonably and consistently
applied. "Operating

<PAGE>   5
EXPENSES" shall mean all expenses and costs of every kind and nature which
Landlord shall pay or become obligated to pay, because of or in connection with
the ownership, management, maintenance, repair, preservation, replacement and
operation of the building or Project and its supporting facilities and such
additional facilities now and in subsequent years as may be determined by
Landlord to be necessary or desirable to the Building and/or Project (as
determined in a reasonable manner) other than those expenses and costs which
are specifically attributable to Tenant or which are expressly made the
financial responsibility of Landlord or specific tenants of the Building or
Project pursuant to this Lease. Operating Expenses shall include, but are not
limited to, the following:

      (1)   TAXES.  All real property taxes and assessments, possessory interest
      taxes, sales taxes, personal property taxes, business or license taxes or
      fees, gross receipts taxes, service payments in lieu of such taxes or
      fees, annual or periodic license or use fees, excises, transit charges,
      and other impositions, general and special, ordinary and extraordinary,
      unforeseen as well as foreseen, of any kind (including fees "in-lieu" of

      charged, confirmed, or imposed by any public authority upon the Building
      or Project, its operations or the Rent (or any portion or component
      thereof), or any tax, assessment or fee imposed in substitution, partially
      or totally, of any of the above. Operating Expenses shall also include any
      taxes, assessments, reassessments, or other fees or impositions with

      repair, use or occupancy of the Premises, Building or Project or any
      portion thereof, including, without limitation, by or for Tenant, and all
      increases therein or reassessments thereof whether the increases or
      reassessments result from increased rate and/or valuation (whether upon a
      transfer of the building or Project or any portion thereof or any interest
      therein or for any other reason). Operating Expenses shall not include
      inheritance or estate taxes imposed upon or assessed against the interest
      of any person in the Project, or taxes computed upon the basis of the net

      landlord as would have been payable to Landlord prior to the payment of
      any such taxes.


      (2)  INSURANCE.  All insurance premiums and costs, including, but not
      limited to, any deductible amounts, premiums and other costs of insurance

           responsibility of Landlord pursuant to Paragraph 10 hereof; those
           items to the extent paid for by the proceeds of insurance; and those
           items attributable solely or jointly to specific tenants of the
           Building or Project.


           (b)  Repairs, replacements, and general maintenance shall include the
           cost of any capital improvements made to or capital assets acquired
           for the Project or Building that in Landlord's discretion may reduce
           any other Operating Expenses, including present or future repair
           work, are reasonably necessary for the health and safety of the
           occupants of the Building or Project, or are required to comply with
           any Regulation, such costs or allocable portions thereof to be
           amortized over such reasonable period as Landlord shall determine,
           together with interest on the unamortized balance at the publicly
           announced "prime rate" charged by Wells Fargo Bank, N.A. (San
           Francisco) or its successor at the time such improvements or capital
           assets are constructed or acquired, plus two (2) percentage points,
           or in the absence of such prime rate, then at the U.S. Treasury
           six-month market note (or bond, if so designated) rate as published
           by any national financial publication selected by Landlord, plus four
           (4) percentage points, but in no event more than the maximum rate
           permitted by law, plus reasonable financing charges.


           (c)  Payment under or for any easement, license, permit, operating
           agreement, declaration, restrictive covenant or instrument relating
           to the Building or project.


           (d)  All expenses and rental related to services and costs of
           supplies, materials and equipment used in operating, managing and
           maintaining the Premises, Building and Project, the equipment therein
           and the adjacent sidewalks, driveways, parking and service areas,
           including, without limitation, expenses related to service agreements
           regarding security, fire and other alarm systems, janitorial
           services, window cleaning, elevator maintenance, Building exterior
           maintenance, landscaping and expenses related to the administration,
           management and operation of the Project, including without limitation
           salaries, wages and benefits and management office rent.

           (e)  the cost of supplying any services and utilities which benefit
           all or a portion of the Premises, Building or Project, including
           without limitation services and utilities provided pursuant to
           Paragraph 15 hereof.

           (f)  Legal expenses and the cost of audits by certified public
           accountants; provided, however, that legal expenses chargeable as
           Operating Expenses shall not include the cost of negotiating leases,
           collecting rents, evicting tenants nor shall it include costs
           incurred in legal proceedings with or against any tenant or to
           enforce the provisions of any lease.

           (g)  A management and accounting cost recovery fee equal to five
           percent (5%) of the sum of the Project's base rents and Operating
           Expenses (other than such management and accounting fee).

If the rentable area of the Building and/or Project is not fully occupied during
any fiscal year of the Term as determined by Landlord, an adjustment may be made
in Landlord's reasonable discretion in computing the Operating Expenses for such
year so that Tenant pays an equitable portion of all variable items (e.g.,
utilities, janitorial services and other component expenses that are affected by
variations in occupancy levels) of Operating Expenses, as reasonably determined
by Landlord; provided, however, that in no event shall Landlord be entitled to
collect in excess of one hundred percent (100%) of the total Operating Expenses
from all of the tenants in the Building or Project, as the case may be.

Operating Expenses shall not include the cost of providing tenant improvements
or other specific costs incurred for the account of, separately billed to and
paid by specific tenants of the Building or Project, the initial construction
cost of the Building, or debt service on any mortgage or deed of trust recorded
with respect to the Project other than pursuant to Paragraph 7.A.(3)(b) above.
Notwithstanding anything herein to the contrary, in any instance wherein
Landlord, in Landlord's reasonable discretion, deems Tenant to be responsible
for any amounts greater than Tenant's Proportionate Share, Landlord shall have
the right to allocate costs in any manner Landlord deems appropriate.



                                       5

The above enumeration of services and facilities shall not be deemed to impose
an obligation on Landlord to make available or provide such services or
facilities except to the extent if any that Landlord has specifically agreed
elsewhere in this Lease to make the same available or provide the same. Without
limiting the generality of the foregoing, Tenant acknowledges and agrees that
it shall be responsible for providing adequate security for its use of the
Premises, the Building and the Project and that Landlord shall have no
obligation or liability with respect thereto, except to the extent if any that
Landlord has specifically agreed elsewhere in this Lease to provide the same.

Notwithstanding anything in the definition of Operating Expenses in this Lease
to the contrary, Operating Expenses shall not include the following, except to
the extent specifically permitted by a specific exception to the following:

      i)    Costs of capital improvements, replacements or equipment and any
depreciation or amortization expenses thereon, except as specifically set forth
in the definition of Operating Expenses in Paragraph 7.A of the Lease;

     ii)    Costs incurred by Landlord due to the violation by Landlord of the
terms and conditions of any lease of space in the Building or the Project;

    iii)    Costs for acquisition of sculpture, paintings or other objects of
art in common areas.

B.    PAYMENT OF ESTIMATED OPERATING EXPENSES. "Estimated Operating Expenses"
for any particular year shall mean Landlord's estimate of the Operating
Expenses for such fiscal year made with respect to such fiscal year as
hereinafter provided. Landlord shall have the right from time to time to revise
its fiscal year and interim accounting periods so long as the periods as so
revised are reconciled with prior periods in a reasonable manner. During the
last month of each fiscal year during the Term, or as soon thereafter as
practicable, Landlord shall give Tenant written notice of the Estimated
Operating Expenses for the ensuing fiscal year. Tenant shall pay Tenant's
Proportionate Share of the Estimated Operating Expenses with installments of
Base Rent for the fiscal year to which the Estimated Operating Expenses applies
in monthly installments on the first day of each calendar month during such
year, in advance. Such payment shall be construed to be Additional Rent for all
purposes hereunder. If at any time during the course of the fiscal year.
Landlord determines that Operating Expenses are projected to vary from the then
Estimated Operating Expenses by more than five percent (5%), Landlord may, by
written notice to Tenant, revise the Estimated Operating Expenses for the
balance of such fiscal year, and Tenant's monthly installments for the
remainder of such year shall be adjusted so that by the end of such fiscal
year Tenant has paid to Landlord Tenant's Proportionate Share of the revised
Estimated Operating Expenses for such year, such revised installment amounts to
be Additional Rent for all purposes hereunder.

C.    COMPUTATION OF OPERATING EXPENSE ADJUSTMENT. "Operating expense
Adjustment" shall mean the difference between Estimated Operating Expenses and
actual Operating Expenses for any fiscal year determined as hereinafter
provided. Within one hundred twenty (120) days after the end of each fiscal
year, or as soon thereafter as practicable, Landlord shall deliver to Tenant a
statement of actual Operating Expenses for the fiscal year just ended,
accompanied by a computation of Operating Expense Adjustment. If such statement
shows that Tenant's payment based upon Estimated Operating Expenses is less
than Tenant's Proportionate Share of Operating Expenses, then Tenant shall pay
to Landlord the difference within twenty (20) days after receipt of such
statement, such payment to constitute Additional Rent for all purposes
hereunder. If such statement shows that Tenant's payments of Estimated
Operating Expenses exceed Tenant's Proportionate Share of Operating Expenses,
then (provided that Tenant is not in default under this Lease) Landlord shall
pay to Tenant the difference within twenty (20) days after delivery of such
statement to Tenant. If this Lease has been terminated or the Term hereof has
expired prior to the date of such statement, then the Operating Expense
Adjustment shall be paid by the appropriate party within twenty (20) days after
the date of delivery of the statement. Should this Lease commence or terminate
at any time other than the first day of the fiscal year, Tenant's Proportionate
Share of the Operating Expense Adjustment shall be prorated based on a month of
30 days and the number of calendar months during such fiscal year that this
Lease is in effect. Notwithstanding anything to the contrary contained in
Paragraph 7.A or 7.B, Landlord's failure to provide any notices or statements
within the time periods specified in those paragraphs shall in no way excuse
Tenant from its obligation to pay Tenant's Proportionate Share of Operating
Expenses.

D.    NET LEASES. This shall be a triple net Lease and Base Rent shall be paid
to Landlord absolutely net of all costs and expenses, except as specifically
provided to the contrary in this Lease.  The provisions for payment of
Operating Expenses and the Operating Expense Adjustment are intended to pass on
to Tenant and reimburse Landlord for all costs and expenses of the nature
described in Paragraph 7.A. incurred in connection with the ownership,
management, maintenance, repair, preservation, replacement and operation of the
Building and/or Project and its supporting facilities and such additional
facilities now and in subsequent years as may be determined by Landlord to be
necessary or desirable to the Building and/or Project.

E.    TENANT AUDIT. If Tenant shall dispute the amount set forth in any
statement provided by Landlord under Paragraph 7.B. or 7.C. above, Tenant shall
have the right, not later than twenty (20) days following receipt of such
statement and upon the condition that Tenant shall first deposit with Landlord
the full amount in dispute, to cause Landlord's books and records with respect
to Operating Expenses for such fiscal year to be audited by certified public
accountants selected by Tenant and subject to Landlord's reasonable right of
approval. The Operating Expense Adjustment shall be appropriately adjusted on
the basis of such audit.  If such audit discloses a liability for a refund in
excess of ten percent (10%) of Tenant's Proportionate Share of the Operating
Expenses previously reported, the cost of such audit shall be borne by
Landlord; otherwise the cost of such audit shall be paid by Tenant. If Tenant
shall not request an audit in accordance with the provisions of this Paragraph
7.E. within twenty (20) days after receipt of Landlord's statement provided
pursuant to Paragraph 7.B. or 7.C., such statement shall be final and binding
for all purposes hereof.

                       8.  INSURANCE AND INDEMNIFICATION



A.    LANDLORD'S INSURANCE.  All insurance maintained by Landlord shall be for
the sole benefit of Landlord and under Landlord's sole control.

      (1)   PROPERTY INSURANCE.  Landlord agrees to maintain property insurance
      insuring the Building against damage or destruction due to risk including
      fire, vandalism, and malicious mischief in an amount not less than the
      replacement cost thereof, in the form and with deductibles and
      endorsements as selected by Landlord. At its election, Landlord may
      instead (but shall have no obligation to) obtain "All Risk" coverage, and
      may also obtain earthquake, pollution, and/or flood insurance in amounts
      selected by Landlord.


      (2)   OPTIONAL INSURANCE. Landlord, at Landlord's option, may also (but
shall have no obligation to) carry insurance against loss of rent, in an amount
equal to the amount of Base Rent and Additional Rent that Landlord could be
required to abate to all Building tenants in the event of condemnation or
casualty damage for a period of twelve (12) months. Landlord may also (but
shall have no obligation to) carry such other insurance as Landlord may
deem prudent or advisable, including, without limitation, liability insurance
in such amounts and on such terms as Landlord shall determine. Landlord shall
not be obligated to insure, and shall have no responsibility whatsoever for any
damage to, any furniture, machinery, goods, inventory or suppliers, or



                                       6
<PAGE>   7
     other personal property or fixtures which Tenant may keep or maintain in
     the Premises, or any leasehold improvements, additions or alterations
     within the Premises.

B.   TENANT'S INSURANCE.

     (1)  PROPERTY INSURANCE. Tenant shall procure at Tenant's sole cost and
     expense and keep in effect from the date of his Lease and at all times
     until the end of the Term, insurance on all personal property and fixtures
     of Tenant and all improvements, additions or alterations made by or for
     Tenant to the Premises on an "All Risk" basis, insuring such property for
     the full replacement value of such property.

     (2)  LIABILITY INSURANCE. Tenant shall procure at Tenant's sole cost and
     expense and keep in effect from the date of this Lease and at all times
     until the end of the Term Commercial General Liability insurance covering
     bodily injury and property damage liability occurring in or about the
     Premises or arising out of the use and occupancy of the Premises and the
     Project, and any part of either, and any areas adjacent thereto, and the
     business operated by Tenant or by any other occupant of the Premises. Such
     insurance shall include contractual liability insurance coverage insuring
     all of Tenant's indemnity obligations under this Lease. Such coverage shall
     have a minimum combined single limit of liability of at least Two Million
     Dollars ($2,000,000.00), and a minimum general aggregate limit of Three
     Million Dollars ($3,000,000.00), with an "Additional Insured -- Managers or
     Lessors of Premises Endorsement." All such policies shall be written to
     apply to all bodily injury (including death), property damage or loss,
     personal and advertising injury and other covered loss, however occasioned,
     occurring during the policy term, shall be endorsed to add Landlord and any
     party holding an interest to which this Lease may be subordinated as an
     additional insured, and shall provide that such coverage shall be "primary"
     and non-contributing with any insurance maintained by Landlord, which shall
     be excess insurance only. Such coverage shall also contain endorsements
     including employees as additional insureds if not covered by Tenant's
     Commercial General Liability Insurance. All such insurance shall provide
     for the severability of interests of insureds; and shall be written on an
     "occurrence" basis, which shall afford coverage for all claims based on
     acts, omissions, injury and damage, which occurred or arose (or the onset
     of which occurred or arose) in whole or in part during the policy period.

     (3)  WORKERS' COMPENSATION AND EMPLOYERS' LIABILITY INSURANCE. Tenant shall
     carry Workers' Compensation Insurance as required by any Regulation,
     throughout the Term at Tenant's sole cost and expense. Tenant shall also
     carry Employers' Liability Insurance in amounts not less than One Million
     Dollars ($1,000,000) each accident for bodily injury by accident; One
     Million Dollars ($1,000,000) policy limit for bodily injury by disease; and
     One Million Dollars ($1,000,000) each employee for bodily injury by
     disease, throughout the Term at Tenant's sole cost and expense.

     (4)  GENERAL INSURANCE REQUIREMENTS. All coverages described in this
     Paragraph 8.B. shall be endorsed to (i) provide Landlord with thirty (30)
     days' notice of cancellation or change in terms; and (ii) waive all rights
     of subrogation by the insurance carrier against Landlord. If at any time
     during the Term the amount or coverage of insurance which Tenant is
     required to carry under this Paragraph 8.B. is, in Landlord's reasonable
     judgment, materially less than the amount or type of insurance coverage
     typically carried by owners or tenants of properties located in the general
     area in which the Premises are located which are similar to and operated
     for similar purposes as the Premises or if Tenant's use of the Premises
     should change with or without Landlord's consent, Landlord shall have the
     right to require Tenant to increase the amount or change the types of
     insurance coverage required under this Paragraph 8.B. All insurance
     policies required to be carried by Tenant under this Lease shall be written
     by companies rated A X or better in "Best's Insurance Guide" and authorized
     to do business in the State of California. In any event deductible amounts
     under all insurance policies required to be carried by Tenant under this
     Lease shall not exceed Five Thousand Dollars ($5,000.00) per occurrence.
     Tenant shall deliver to Landlord on or before the Term Commencement Date,
     and thereafter at least thirty (30) days before the expiration dates of the
     expired policies, certified copies of Tenant's insurance policies, or a
     certificate evidencing the same issued by the insurer thereunder, and, if
     Tenant shall fail to procure such insurance, or to deliver such policies or
     certificates, Landlord may, at Landlord's option and in addition to
     Landlord's other remedies in the event of a default by Tenant hereunder,
     procure the same for the account of Tenant, and the cost thereof shall be
     paid to Landlord as Additional Rent.

C.   INDEMNIFICATION. Tenant shall indemnify, defend by counsel reasonably
acceptable to Landlord, protect and hold Landlord harmless from and against any
and all claims, liabilities, losses, costs, loss of rents, liens, damages,
injuries or expenses, including reasonable attorneys' and consultants' fees and
court costs, demands, causes of action, or judgments, directly or indirectly
arising out of or related to: (1) claims of injury to or death of persons or
damage to property occurring or resulting directly or indirectly from the use or
occupancy of the Premises, Building or Project by Tenant or Tenant's Parties, or
from activities or failures to act of Tenant or Tenant's Parties; (2) claims
arising from work or labor performed, or for materials or supplies furnished to
or at the request or for the account of Tenant in connection with performance of
any work done for the account of Tenant within the Premises or Project; (3)
claims arising from any breach or default on the part of Tenant in the
performance of any covenant contained in this Lease; and (4) claims arising from
the negligence or intentional acts or omissions of Tenant or Tenant's Parties.
The foregoing indemnity by Tenant shall not be applicable to claims to the
extent arising from the gross negligence or willful misconduct of Landlord.
Landlord shall not be liable to Tenant and Tenant hereby waives all claims
against Landlord for any injury or damage to any person or property in or about
the Premises, Building or Project by or from any cause whatsoever (other than
Landlord's gross negligence or willful misconduct) and, without limiting the
generality of the foregoing, whether caused by water leakage of any character
from the roof, walls, basement or other portion of the Premises, Building or
Project, or caused by gas, fire, oil or electricity in, on or about the
Premises, Building or Project. The provisions of this Paragraph shall survive
the expiration or earlier termination of this Lease.

                            9. WAIVER OF SUBROGATION

     To the extent permitted by law and without affecting the coverage provided
by insurance to be maintained hereunder or any other rights or remedies,
Landlord and Tenant each waive any right to recover against the other for: (a)
damages for injury to or death of persons; (b) damage to property, including
personal property; (c) damages to the Premises or any part thereof; and (d)
claims arising by reason of the foregoing due to hazards covered by insurance
maintained or required to be maintained pursuant to this Lease to the extent of
proceeds recovered therefrom, or proceeds which would have been recoverable
therefrom in the case of the failure of any party to maintain any insurance
coverage required to be maintained by such party pursuant to this Lease. This
provision is intended to waive fully, any rights and/or claims arising by reason
of the foregoing, but only to the extent that any of the foregoing damages
and/or claims referred to above are covered or would be covered, and only to the
extent of such coverage, by insurance actually carried or required to be
maintained pursuant to this Lease by either Landlord or Tenant. This provision
is also intended to waive fully, and for the benefit of each party, any rights
and/or claims which might give rise to a right of subrogation on any insurance
carrier. Subject to all qualifications of this Paragraph 9, Landlord waives its
rights as specified in this Paragraph 9 with respect to any subtenant that it
has approved pursuant to Paragraph 2.1 but only in exchange for the written
waiver of such rights to be given by such subtenant to Landlord upon such
subtenant taking possession of the Premises or a portion thereof. Each party
shall cause each insurance policy obtained by it to provide that the insurance
company waives all right of recovery by way of subrogation against either party
in connection with any damage covered by any policy.

                                       7
<PAGE>   8
                    10.  LANDLORD'S REPAIRS AND MAINTENANCE.

Landlord shall at Landlord's expense maintain in good repair, reasonable wear
and tear excepted, the structural soundness of the roof, foundations, and
exterior walls of the Building. The term "exterior walls" as used herein shall
not include windows, glass or plate glass, doors, special store fronts or office
entries. Any damage caused by or repairs necessitated by any negligence or act
of Tenant or Tenant's Parties may be repaired by Landlord at Landlord's option
and Tenant's expense. Tenant shall immediately give Landlord written notice of
any defect or need of repairs in such components of the Building for which
Landlord is responsible, after which Landlord shall have a reasonable
opportunity and the right to enter the Premises at all reasonable times to
repair same. Landlord's liability with respect to any defects, repairs, or
maintenance for which Landlord is responsible under any of the provisions of
this Lease shall be limited to the cost of such repairs or maintenance, and
there shall be no abatement of rent and no liability of Landlord by reason of
any injury to or interference with Tenant's business arising from the making of
repairs, alterations or improvements in or to any portion of the Premises, the
Building or the Project or to fixtures, appurtenances or equipment in the
Building, except as provided in Paragraph 24. By taking possession of the
Premises, Tenant accepts them "as is," as being in good order, condition and
repair and the condition in which Landlord is obligated to deliver them and
suitable for the Permitted Use and Tenant's intended operations in the Premises,
whether or not any notice of acceptance is given.


                      11. TENANT'S REPAIRS AND MAINTENANCE

     Tenant shall at all times during the Term at Tenant's expense maintain all
parts of the Premises and such portions of the Building as are within the
exclusive control of Tenant in a first-class, good, clean and secure condition
and promptly make all necessary repairs and replacements, as determined by
Landlord, with materials and workmanship of the same character, kind and quality
as the original. Notwithstanding anything to the contrary contained herein,
Tenant shall, at its expense, promptly repair any damage to the Premises or the
Building or Project resulting from or caused by any negligence or act of Tenant
or Tenant's Parties.


                                12. ALTERATIONS

A.   Tenant shall not make, or allow to be made, any alterations, physical
additions, improvements or partitions, including without limitation the
attachment of any fixtures or equipment, in, about or to the Premises
("ALTERATIONS") without obtaining the prior written consent of Landlord, which
consent shall not be unreasonably withheld with respect to proposed Alterations
which: (a) comply with all applicable Regulations; (b) are, in Landlord's
opinion, compatible with the Building or the Project and its mechanical,
plumbing, electrical, heating/ventilation/air conditioning systems, and will not
cause the Building or Project or such systems to be required to be modified to
comply with any Regulations (including, without limitation, the Americans With
Disabilities Act); and (c) will not interfere with the use and occupancy of any
other portion of the Building or Project by any other tenant or its invitees.
Specifically, but without limiting the generality of the foregoing, Landlord
shall have the right of written consent for all plans and specifications for the
proposed Alterations, construction means and methods, all appropriate permits
and licenses, any contractor or subcontractor to be employed on the work of
Alterations, and the time for performance of such work, and may impose rules and
regulations for contractors and subcontractors performing such work. Tenant
shall also supply to Landlord any documents and information reasonably requested
by Landlord in connection with Landlord's consideration of a request for
approval hereunder. Tenant shall cause all Alterations to be accomplished in a
first-class, good and workmanlike manner, and to comply with all applicable
Regulations and Paragraph 27 hereof. Tenant shall at Tenant's sole expense,
perform any additional work required under applicable Regulations due to the
Alterations hereunder. No review or consent by Landlord of or to any proposed
Alteration or additional work shall constitute a waiver of Tenant's obligations
under this Paragraph 12, nor constitute any warranty or representation that the
same complies with all applicable Regulations, for which Tenant shall at all
times be solely responsible. Tenant shall reimburse Landlord for all costs which
landlord may incur in connection with granting approval to Tenant for any such
Alterations, including any costs or expenses which Landlord may incur in
electing to have outside architects and engineers review said plans and
specifications, and shall pay landlord an administration fee of fifteen percent
(15%) of the cost of the Alterations as Additional Rent hereunder. All such
Alterations shall remain the property of Tenant until the expiration or earlier
termination of this Lease, at which time they shall be and become the property
of Landlord; provided, however, that Landlord may, at Landlord's option, require
that Tenant, at Tenant's expense, remove any or all Alterations made by Tenant
and restore the Premises by the expiration or earlier termination of this Lease,
to their condition existing prior to the construction of any such Alterations.
All such removals and restoration shall be accomplished in a first-class and
good and workmanlike manner so as not to cause any damage to the Premises or
Project whatsoever. If Tenant fails to remove such Alterations or Tenant's trade
fixtures or furniture or other personal property, Landlord may keep and use them
or remove any of them and cause them to be stored or sold in accordance with
applicable law, at Tenant's sole expense. In addition to and wholly apart from
Tenant's obligation to pay Tenant's Proportionate Share of Operating Expenses,
Tenant shall be responsible for and shall pay prior to delinquency any taxes or
governmental service fees, possessory interest taxes, fees or charges in lieu of
any such taxes, capital levies, or other charges imposed upon, levied with
respect to or assessed against its fixtures or personal property, on the value
of Alterations within the Premises, and on Tenant's interest pursuant to this
Lease, or any increase in any of the foregoing based on such Alterations. To the
extent that any such taxes are not separately assessed or billed to Tenant,
Tenant shall pay the amount thereof as invoiced to Tenant by Landlord.

Notwithstanding the foregoing, at Landlord's option (but without obligation),
all or any portion of the Alterations shall be performed by Landlord for
Tenant's account and Tenant shall pay Landlord's estimate of the cost thereof
(including a reasonable charge for Landlord's overhead and profit) prior to
commencement of the work. In addition, at Landlord's election and
notwithstanding the foregoing, however, Tenant shall pay to Landlord the cost of
removing any such Alterations and restoring the Premises to their original
condition such cost to include a reasonable charge for Landlord's overhead and
profit as provided above, and such amount may be deducted from the Security
Deposit or any other sums or amounts held by Landlord under this Lease.

B.   In compliance with Paragraph 27 hereof, at least ten (10) business days
before beginning construction of any Alteration, Tenant shall give Landlord
written notice of the expected commencement date of that construction to permit
Landlord to post and record a notice of non-responsibility. Upon substantial
completion of construction, if the law so provides, Tenant shall cause a timely
notice of completion to be recorded in the office of the recorder of the county
in which the Building is located.


                                   13.  SIGNS

Tenant shall not place, install, affix, paint or maintain any signs, notices,
graphics or banners whatsoever or any window decor which is visible in or from
public view or corridors, the common areas or the exterior of the Premises or
the Building, in or on any exterior window or window fronting upon any common
areas or service area without Landlord's prior written approval which Landlord
shall have the right to withhold in its absolute and sole discretion; provided
that Tenant's name shall be included in any Building-standard door and directory
signage, if any, in accordance with Landlord's Building signage program,
including without limitation, payment by Tenant of any fee charged by Landlord
for maintaining such signage, which fee shall constitute Additional Rent
hereunder. Any installation of signs, notices, graphics or banners on or about
the Premises or Project approved by Landlord shall be subject to any Regulations
and to any other requirements imposed by Landlord. Tenant shall remove all such
signs or graphics by the expiration or any earlier termination of this Lease.
Such installations and removals shall be made in such manner as to avoid injury
to or defacement of the Premises, Building or Project and any other improvements
contained therein, and Tenant shall repair any injury or defacement including
without limitation discoloration caused by such installation or removal.

<PAGE>   9
                        14.  INSPECTION/POSTING NOTICES

After reasonable notice, except in emergencies where no such notice shall be
required, Landlord and Landlord's agents and representatives, shall have the
right to enter the Premises to inspect the same, to clean, to perform such work
as may be permitted or required hereunder, to make repairs, improvements or
alterations to the Premises, Building or Project or to other tenant spaces
therein, to deal with emergencies, to post such notices as may be permitted or
required by law to prevent the perfection of liens against Landlord's interest
in the Project or to exhibit the Premises to prospective tenants, purchasers,
encumbrancers or to others, or for any other purpose as Landlord may deem
necessary or desirable; provided, however, that Landlord shall use reasonable
efforts not to unreasonably interfere with Tenant's business operations. Tenant
shall not be entitled to any abatement of Rent by reason of the exercise of any
such right of entry. Tenant waives any claim for damages for any injury or
inconvenience to or interference with Tenant's business, any loss of occupancy
or quiet enjoyment of the Premises, and any other loss occasioned thereby.
Landlord shall at all times have and retain a key with which to unlock all of
the doors in, upon and about the Premises, excluding Tenant's vaults and safes
or special security areas (designated in advance), and Landlord shall have the
right to use any and all means which Landlord may deem necessary or proper to
open said doors in an emergency, in order to obtain entry to any portion of the
Premises, and any entry to the Premises or portions thereof obtained by
Landlord by any of said means, or otherwise, shall not be construed to be a
forcible or unlawful entry into, or a detainer of, the Premises, or an
eviction, actual or constructive, of Tenant from the Premises or any portions
thereof. At any time within six (6) months prior to the expiration of the Term
or following any earlier termination of this Lease or agreement to terminate
this Lease, Landlord shall have the right to erect on the Premises, Building
and/or Project a suitable sign indicating that the Premises are available for
lease.

                          15.  SERVICES AND UTILITIES

A.   Subject to the provisions elsewhere herein contained and to the rules and
regulations of the Building, Landlord shall furnish to the Premises during
ordinary business hours of generally recognized business days, to be determined
by Landlord (but exclusive, in any event, of Saturdays, Sundays and legal
holidays), water for lavatory and drinking purposes and electricity, heat and
air conditioning as usually furnished or supplied for use of the Premises, for
reasonable and normal office use as of the date Tenant takes possession of the
Premises as determined by Landlord (but not including above-standard or
continuous cooling for excessive heat-generating machines, excess lighting or
equipment), janitorial services during the times and in the manner that such
services are, in Landlord's judgment, customarily furnished in comparable
office buildings in the immediate market area, and elevator service, which
shall mean service either by nonattended automatic elevators or elevators with
attendants, or both, at the option of Landlord. Tenant acknowledges that Tenant
has inspected and accepts the water, electricity, heat and air conditioning and
other utilities and services being supplied or furnished to the Premises as of
the date Tenant takes possession of the Premises, as being sufficient for use
of the Premises for reasonable and normal office use in their present condition,
"as is," and suitable for the Permitted Use, and for Tenant's intended
operations in the Premises. Landlord shall have no obligation to provide
additional or after-hours electricity, heating or air conditioning, but if
Landlord elects to provide such services at Tenant's request, Tenant shall pay
to Landlord's reasonable charge for such services as determined by Landlord.
Tenant agrees to keep and cause to be kept closed all window covering when
necessary because of the sun's position, and Tenant also agrees at all times to
cooperate fully with Landlord and to abide by all of the regulations and
requirements which Landlord may prescribe for the proper functioning and
protection of electrical, heating, ventilating and air conditioning systems.
Wherever heat-generating machines, excess lighting or equipment are used in the
Premises which affect the temperature otherwise maintained by the air
conditioning system, Landlord reserves the right to install supplementary air
conditioning units in the Premises and the cost thereof, including the cost of
installation and the cost of operation and maintenance thereof, shall be paid
by Tenant to Landlord upon demand by Landlord.

B.   Tenant shall not without written consent of Landlord use any apparatus,
equipment or device in the Premises, including without limitation, computers,
electronic data processing machines, copying machines, and other machines,
using excess lighting or using electric current, water, or any other resource
in excess of or which will in any way increase the amount of electricity,
water, or any other resource being furnished or supplied for the use of the
Premises for reasonable and normal office use, in each case as of the date
Tenant takes possession of the Premises as determined by Landlord, or which
will require additions or alterations to or interfere with the Building power
distribution systems; nor connect with electric current, except through
existing electrical outlets in the Premises or water pipes, any apparatus,
equipment or device for the purpose of using electrical current, water, or any
other resource. If Tenant shall require water or electric current or any other
resource in excess of that being furnished or supplied for the use of the
Premises as of the date Tenant takes possession of the Premises as determined by
Landlord, Tenant shall first procure the written consent of Landlord which
Landlord may refuse, to the use thereof, and Landlord may cause a special meter
to be installed in the Premises so as to measure the amount of water, electric
current or other resource consumed for any such other use. Tenant shall pay
directly to Landlord as an addition to and separate from payment of Operating
Expenses the cost of all such additional resources, energy, utility service and
meters (and of installation, maintenance and repair thereof and of any
additional circuits or other equipment necessary to furnish such additional
resources, energy, utility or service). Landlord may add to the separate or
metered charge a recovery of additional expense incurred in keeping account of
the excess water, electric current or other resource so consumed. Landlord
shall not be liable for any damages directly or indirectly resulting from nor
shall the Rent or any monies owed Landlord under this Lease herein reserved be
abated by reason of: (a) the installation, use or interruption of use of any
equipment used in connection with the furnishing of any such utilities or
services, or any change in the character or means of supplying or providing any
such utilities or services or any supplier thereof; (b) the failure to furnish
or delay in furnishing any such utilities or services when such failure or
delay is caused by acts of God or the elements, labor disturbances of any
character, or any other accidents or other conditions beyond the reasonable
control of Landlord or because of any interruption of service due to Tenant's
use of water, electric current or other resource in excess of that being
supplied or furnished for the use of the Premises as of the date Tenant takes
possession of the Premises; (c) the inadequacy, limitation, curtailment,
rationing or restriction on use of water, electricity, gas or any other form of
energy or any other service or utility whatsoever serving the Premises or
Project, whether by Regulation or otherwise; or (d) the partial or total
unavailability of any such utilities or services to the Premises or the
Building, whether by Regulation or otherwise; nor shall any such occurrence
constitute an actual or constructive eviction of Tenant. Landlord shall further
have no obligation to protect or preserve any apparatus, equipment or device
installed by Tenant in the Premises, including without limitation by providing
additional or after-hours heating or air conditioning. Landlord shall be
entitled to cooperate voluntarily and in a reasonable manner with the efforts
of national, state or local governmental agencies or utility suppliers in
reducing energy or other resource consumption. The obligation to make services
available hereunder shall be subject to the limitations of any such voluntary,
reasonable program. In addition, Landlord reserves the right to change the
supplier or provider of any such utility or service from time to time. Tenant
shall have no right to contract with or otherwise obtain any electrical or
other such service for or with respect to the Premises or Tenant's operations
therein from any supplier or provider of any such service. Tenant shall
cooperate with Landlord and any supplier or provider of such services
designated by Landlord from time to time to facilitate the delivery of such
services to Tenant at the Premises and to the Building and Project, including
without limitation allowing Landlord and Landlord's suppliers or providers, and
their respective agents and contractors, reasonable access to the Premises for
the purpose of installing, maintaining, repairing, replacing or upgrading such
service or any equipment or machinery associated therewith.

C.   Tenant shall pay, upon demand, for all utilities furnished to the
Premises, or if not separately billed to or metered to Tenant, Tenant's
Proportionate Share of all charges jointly serving the Project in accordance
with Paragraph 7. All sums payable under this Paragraph 15 shall constitute
Additional Rent hereunder.

                               16.  SUBORDINATION

Without the necessity of any additional document being executed by Tenant for
the purpose of effecting a subordination, this Lease shall be and is hereby
declared to be subject and subordinate at all times to: (a) all ground leases or
underlying leases which may now exist or hereafter be executed affecting the
Premises and/or the land upon which the Premises and Project are situated, or
both; and (b) any mortgage or deed of trust which may now exist or be placed
upon the Building, the Project and/or the land upon which the Premises or the
Project are situated, or said ground leases or underlying leases, or Landlord's
interest or estate in any of said items which is specified as security.
Notwithstanding the foregoing, Landlord shall have the right to subordinate or
cause to be subordinated any such ground leases or underlying leases or any such
liens to this Lease. If any ground lease or underlying lease terminates for any
reason or any mortgage or deed of trust is foreclosed or a conveyance in lieu of
foreclosure is made for any reason, Tenant shall, notwithstanding any
subordination, attorn to and become the Tenant of the successor in interest to
Landlord provided that Tenant shall not be disturbed in its possession under
this Lease by such successor in interest so long as Tenant is not in default
under this Lease. Within ten (10) days after request by Landlord, Tenant shall
execute and deliver any additional documents evidencing Tenant's attornment or
the subordination of this Lease with respect to any such ground leases or
underlying leases or any such mortgage or deed of trust, in the form reasonably
requested by Landlord or by any ground landlord, mortgage, or beneficiary under
a deed of trust, subject to such nondisturbance requirement. If requested in
writing by Tenant, Landlord shall use commercially reasonable efforts to obtain
a subordination, nondisturbance and attornment agreement for the benefit of
Tenant reflecting the foregoing from any ground Landlord, mortgagee or
beneficiary, at Tenant's expense, subject to such other terms and conditions as
the ground landlord, mortgage or beneficiary may reasonably require.

                           17.  FINANCIAL STATEMENTS

At the request of Landlord from time to time, Tenant shall provide to Landlord
Tenant's and any guarantor's current financial statements or other information
discussing financial worth of Tenant and any guarantor, which Landlord shall
keep confidential and use solely for purposes of this Lease and in connection
with the ownership, management, financing and disposition of the Project.

                           18.  ESTOPPEL CERTIFICATE

Tenant agrees from time to time, within ten (10) days after request of Landlord,
to deliver to Landlord, or Landlord's designee, an estoppel certificate stating
that this Lease is in full force and effect, that this Lease has not been
modified (or stating all modifications, written or oral, to this Lease), the
date to which Rent has been paid, the unexpired portion of this Lease, that
there are no current defaults by Landlord or Tenant under this Lease (or
specifying any such defaults), that the leasehold estate granted by this Lease
is the sole interest of Tenant in the Premises and/or the land at which the
Premises are situated, and such other matters pertaining to this Lease as may be
reasonably requested by Landlord or any mortgagee, beneficiary, purchaser or
prospective purchaser of the Building or Project or any interest therein.
Failure by Tenant to execute and deliver such certificate shall constitute an
acceptance of the Premises and acknowledgment by Tenant that the statements
included are true and correct without exception. Tenant agrees that if Tenant
fails to execute and deliver such certificate within such ten (10) day period,
Landlord may execute and deliver such certificate on Tenant's behalf and that
such certificate shall be binding on Tenant. Landlord and Tenant intend that any
statement delivered pursuant to this Paragraph may be relied upon by any
mortgagee, beneficiary, purchaser or prospective purchaser of the Building or
Project or any interest therein. The parties agree that Tenant's obligation to
furnish such estoppel certificate in a timely fashion is a material inducement
for Landlord's execution of this Lease, and shall be an event of default
(without any cure period that might be provided under Paragraph 26.A(3) of this
Lease) if Tenant fails to fully comply or makes any material misstatement in any
such certificate.

                             19.  SECURITY DEPOSIT

Tenant agrees to deposit with Landlord upon execution of this Lease, a security
deposit as stated in the Basic Lease information (the "SECURITY DEPOSIT"), which
sum shall be held and owned by Landlord, without obligation to pay interest, as
security for the performance of Tenant's covenants and obligations under this
Lease. The Security Deposit is not an advance rental deposit or a measure of
damages incurred by Landlord in case of Tenant's default. Upon the occurrence of
any event of default by Tenant, Landlord may from time to time, without
prejudice to any other remedy provided herein or by law, use such fund as a
credit to the extent necessary to credit against any arrears of rent or other
payments due to Landlord hereunder, and any other damage, injury, expense or
liability caused by such event of default, and Tenant shall pay to Landlord, on
demand, the amount so applied in order to restore the Security Deposit to its
original amount. Although the Security Deposit shall be deemed the property of
Landlord, any remaining balance of such deposit shall be returned by Landlord to
Tenant at such time after termination of this Lease that all of Tenant's
obligations under this Lease have been fulfilled, reduced by such amounts as may
be required by Landlord to remedy defaults on the part of Tenant in the payment
of Rent or other obligations of Tenant under this Lease, to repair damage to the
Premises, Building or Project caused by Tenant or any Tenant's Parties and to
close the Premises. Landlord may use and commingle the Security Deposit with
other funds of Landlord.

                      20.  LIMITATION OF TENANT'S REMEDIES

The obligations and liability of Landlord to Tenant for any default by Landlord
under the terms of this Lease are not personal obligations of Landlord or of the
individual or other partners of Landlord or its or their partners, directors,
officers, or shareholders, and Tenant agrees to look solely to Landlord's
interest in the Project for the recovery of any amount from Landlord, and shall
not look to other assets of Landlord nor seek recourse against the assets of the
individual or other partners of Landlord or its or their partners, directors,
officers or shareholders. Any lien obtained to enforce any such judgment and any
levy of execution thereon shall be subject and subordinate to any liens,
mortgage or deed of trust on the Project. Under no circumstances shall Tenant
have the right to offset against or recoup Rent or other payments due and to
become due to Landlord hereunder except as expressly provided in Paragraph 23.B.
below, which Rent and other payments shall be absolutely due and payable
hereunder in accordance with the terms hereof.

                         21.  ASSIGNMENT AND SUBLETTING

A.   (1)  GENERAL. This Lease has been negotiated to be and is granted as
     an accommodation to Tenant. Accordingly, this Lease is personal to Tenant
     and Tenant's rights granted hereunder do not include the right to assign
     this Lease or sublease the Premises, or to receive any excess, either in
     installments or lump sum, over the Rent which is expressly reserved by
     Landlord as hereinafter provided, except as otherwise expressly hereinafter
     provided. Tenant shall not assign or pledge this Lease or sublet the
     Premises or any part thereof, whether voluntarily or by operation of law,
     or permit the use or occupancy of the Premises or any part thereof by
     anyone other than Tenant, or suffer or permit any such assignment, pledge,
     subleasing or occupancy, without Landlord's prior written consent except as
     provided herein. If Tenant desires to assign this Lease or sublet any or
     all of the Premises, Tenant shall give Landlord written notice (the
     "TRANSFER NOTICE") at least thirty (30) days prior to the anticipated
     effective date of the proposed assignment or sublease, which shall contain
     all of the information reasonably requested by Landlord to address
     Landlord's decision criteria specified hereinafter. Landlord shall then
     have a period of fifteen (15) days following receipt of the Transfer Notice
     to notify Tenant in writing that Landlord elects either: (i) to terminate
     this Lease as to the space so affected as of the date so requested by
     Tenant; or (ii) to consent to the proposed assignment or sublease, subject,
     however, to Landlord's prior written consent of the proposed assignee or
     subtenant and of any related documents or agreements associated with the
     assignment or sublease. If Landlord should fail to notify Tenant in writing
     of such election



                                       10
<PAGE>   11
     within said period, Landlord shall be deemed to have waived option (1)
     above, but written consent by ???????? assignee or subtenant shall still be
     required. If Landlord does not exercise option (1) above, Landlord's
     consent to a proposed assignment or sublease shall not be unreasonably
     withheld. Consent to any assignment or subletting shall not constitute
     consent to any subsequent transaction to which this Paragraph 21 applies.

(2)  CONDITIONS OF LANDLORD'S CONSENT. Without limiting the other instances in
     which it may be reasonable for Landlord to withhold Landlord's consent to
     an assignment or subletting, Landlord and Tenant acknowledge that it shall
     be reasonable for Landlord to withhold Landlord's consent in the following
     instances: if the proposed assignee does not agree to be bound by and
     assume the obligations of Tenant under this Lease in form and substance
     satisfactory to Landlord; the use of the Premises by such proposed assignee
     or subtenant would not be a Permitted Use or would violate any exclusivity
     or other arrangement which Landlord has with any other tenant or occupant
     or any Regulation or would increase the Occupancy Density or Parking
     Density of the Building or Project, or would otherwise result in an
     undesirable tenant mix for the Project as determined by Landlord; the
     proposed assignee or subtenant is not of sound financial condition as
     determined by Landlord in Landlord's sole discretion; the proposed assignee
     or subtenant is a governmental agency; the proposed assignee or subtenant
     does not have a good reputation as a tenant of property or a good business
     reputation; the proposed assignee or subtenant is a person with whom
     Landlord is negotiating to lease space in the Project or is a present
     tenant of the Project; the assignment or subletting would entail any
     Alterations which would lessen the value of the leasehold improvements in
     the Premises or use of any Hazardous Materials or other noxious use or use
     which may disturb other tenants of the Project; or Tenant is in default of
     any obligation of Tenant under this Lease, or Tenant has defaulted under
     this Lease on three (3) or more occasions during any twelve (12) months
     preceding the date that Tenant shall request consent. Failure by or refusal
     of Landlord to consent to a proposed assignee or subtenant shall not cause
     a termination of this Lease. Upon a termination under Paragraph 21.1(1)(i),
     Landlord may lease the Premises to any party, including parties with whom
     Tenant has negotiated an assignment or sublease, without incurring any
     liability to Tenant. At the option of Landlord, a surrender and termination
     of this Lease shall operate as an assignment to Landlord of some or all
     subleases or subtenancies. Landlord shall exercise this option by giving
     notice of that assignment to such subtenants on or before the effective
     date of the surrender and termination. In connection with each request for
     assignment or subletting, Tenant shall pay to Landlord Landlord's standard
     fee for approving such requests, as well as all costs incurred by Landlord
     or any mortgagee or ground lessor in approving each such request and
     effecting any such transfer, including, without limitation, reasonable
     attorneys' fees.

B.   BONUS RENT. Any Rent or other consideration realized by Tenant under any
     such sublease or assignment in excess of the Rent payable hereunder, after
     amortization of a reasonable brokerage commission incurred by Tenant, shall
     be divided and paid, ten percent (10%) to Tenant, ninety percent (90%) to
     Landlord. In any subletting or assignment undertaken by Tenant, Tenant
     shall diligently seek to obtain the maximum rental amount available in the
     marketplace for comparable space available for primary leasing.

C.   CORPORATION. If Tenant is a corporation, a transfer of corporate shares by
     sale, assignment, bequest, inheritance, operation of law or other
     disposition (including such a transfer to or by a receiver or trustee in
     federal or state bankruptcy, insolvency or other proceedings) resulting in
     a change in the present control of such corporation or any of its parent
     corporations, not including any public offering of shares by the person or
     persons owning a majority of said corporate shares, shall constitute an
     assignment for purposes of this Lease.

D.   UNINCORPORATED ENTITY. If Tenant is a partnership, joint venture,
     unincorporated limited liability company or other unincorporated business
     form, a transfer of the interest of persons, firms or entities responsible
     for managerial control of Tenant by sale, assignment, bequest, inheritance,
     operation of law or other disposition, so as to result in a change in the
     present control of said entity and/or of the underlying beneficial
     interests of said entity and/or a change in the identity of the persons
     responsible for the general credit obligations of said entity shall
     constitute an assignment for all purposes of this Lease.

E.   LIABILITY. No assignment or subletting by Tenant, permitted or otherwise,
     shall relieve Tenant of any obligation under this Lease or alter the
     primary liability of the Tenant named herein for the payment of Rent or for
     the performance of any other obligations to be performed by Tenant,
     including obligations contained in Paragraph 25 with respect to any
     assignee or subtenant. Landlord may collect rent or other amounts or any
     portion thereof from any assignee, subtenant, or other occupant of the
     Premises, permitted or otherwise, and apply the net rent collected to the
     Rent payable hereunder, but no such collection shall be deemed to be a
     waiver of this Paragraph 21, or the acceptance of the assignee, subtenant
     or occupant as tenant, or a release of Tenant from the further performance
     by Tenant of the obligations of Tenant under this Lease. Any assignment or
     subletting which conflicts with the provisions hereof shall be void.

                                 22. AUTHORITY

Landlord represents and warrants that it has full right and authority to enter
into this Lease and to perform all of Landlord's obligations hereunder and that
all persons signing this Lease on its behalf are authorized to do. Tenant and
the person or persons, if any, signing on behalf of Tenant, jointly and
severally represent and warrant that Tenant has full right and authority to
enter into this Lease, and to perform all of Tenant's obligations hereunder, and
that all persons signing this Lease on its behalf are authorized to do so.

                                23. CONDEMNATION

A.   CONDEMNATION RESULTING IN TERMINATION. If the whole or any substantial
party of the Premises should be taken or condemned for any public use under any
Regulation, or by right of eminent domain, or by private purchase in lieu
thereof, and the taking would prevent or materially interfere with the Permitted
Use of the Premises, either party shall have the right to terminate this Lease
at its option. If any material portion of the Building or Project is taken or
condemned for any public use under any Regulation, or by right of eminent
domain, or by private purchase in lieu thereof, Landlord may terminate this
Lease at its option. In either of such events, the Rent shall be abated during
the unexpired portion of this Lease, effective when the physical taking of said
Premises shall have occurred.

B.   CONDEMNATION NOT RESULTING IN TERMINATION. If a portion of the Project of
which the Premises are a part should be taken or condemned for any public use
under any Regulation, or by right of eminent domain, or by private purchase in
lieu thereof, and the taking prevents or materially interferes with the
Permitted Use of the Premises, and this Lease is not terminated as provided in
Paragraph 23.A. above, the Rent payable hereunder during the unexpired portion
of this Lease shall be reduced, beginning on the date when the physical taking
shall have occurred, to such amount as may be fair and reasonable under all of
the circumstances, but only after giving Landlord credit for all sums received
or to be received by Tenant by the condemning authority. Notwithstanding
anything to the contrary contained in this Paragraph, if the temporary use or
occupancy of any part of the Premises shall be taken or appropriated under power
of eminent domain during the Term, this Lease shall be and remain unaffected by
such taking or appropriation and Tenant shall continue to pay in full all Rent
payable hereunder by Tenant during the Term; in the event of any such temporary
appropriation or taking, Tenant shall be entitled to receive that portion of any
award which represents compensation for the use of or occupancy of the Premises
during the Term, and

                                       11
<PAGE>   12
Landlord shall be entitled to receive that portion of any award which represents
the cost of restoration of the Premises and the use and occupancy of the
Premises.

C.   AWARD. Landlord shall be entitled to (and Tenant shall assign to Landlord)
any and all payment, income, rent, award or any interest therein whatsoever
which may be paid or made in connection with such taking or conveyance and
Tenant shall have no claim against Landlord or otherwise for any sums paid by
virtue of such proceedings, whether or not attributable to the value of any
unexpired portion of this Lease, except as expressly provided in this Lease.
Notwithstanding the foregoing, any compensation specifically and separately
awarded Tenant for Tenant's personal property and moving costs, shall be and
remain the property of Tenant.

D.   WAIVER OF CCP SECTION 1265.130. Each party waives the provisions of
California Civil Code Procedure Section 1265.130 allowing either party to
petition the superior court to terminate this Lease as a result of a partial
taking.

                              24. CASUALTY DAMAGE

A.   GENERAL. If the Premises or Building should be damaged or destroyed by
fire, tornado, or other casualty (collectively, "Casualty"), Tenant shall give
immediate written notice thereof to Landlord. Within thirty (30) days after
Landlord's receipt of such notice, Landlord shall notify Tenant whether in
Landlord's reasonable estimation material restoration of the Premises can
reasonably be made within one hundred eighty (180) days from the date of such
notice and receipt of required permits for such restoration. Landlord's
reasonable determination shall be binding on Tenant.

B.   WITHIN 180 DAYS. If the Premises or Building should be damaged by Casualty
to such extent that material restoration can in Landlord's estimation be
reasonably completed within one hundred eighty (180) days after the date of such
notice and receipt of required permits for such restoration, this Lease shall
not terminate. Provided that insurance proceeds are received by Landlord to
fully repair the damage, Landlord shall proceed to rebuild and repair the
Premises in the manner determined by Landlord, except that Landlord shall not be
required to rebuild, repair or replace any part of the Alterations which may
have been placed on or about the Premises by Tenant. If the Premises are
untenantable in whole or in part following such damage, the Rent payable
hereunder during the period in which they are untenantable shall be abated
proportionately, but only to the extent of rental abatement insurance proceeds
received by Landlord during the time and to the extent the Premises are unfit
for occupancy.

C.   GREATER THAN 180 DAYS. If the Premises or building should be damaged by
Casualty to such extent that rebuilding or repairs cannot in Landlord's
estimation be reasonably completed within one hundred eighty (180) days after
the date of such notice and receipt of required permits for such rebuilding or
repair, then Landlord shall have the option of either: (1) terminating this
Lease effective upon the date of the occurrence of such damage, in which event
the Rent shall be abated during the unexpired portion of this Lease; or (2)
electing to rebuild or repair the Premises diligently and in the manner
determined by Landlord. Landlord shall notify Tenant of its election within
thirty (30) days after Landlord's receipt of notice of the damage or
destruction. Notwithstanding the above, Landlord shall not be required to
rebuild, repair or replace any part of any Alterations which may have been
placed, on or about the Premises by Tenant. If the Premises are untenantable in
whole or in part following such damage, the Rent payable hereunder during the
period in which they are untenantable shall be abated proportionately, but only
to the extent of rental abatement insurance proceeds received by Landlord during
the time and to the extent the Premises are unfit for occupancy.

D.   TENANT'S FAULT. Notwithstanding anything herein to the contrary, if the
Premises or any other portion of the Building are damaged by Casualty resulting
from the fault, negligence, or breach of this Lease by Tenant or any of Tenant's
Parties, Base Rent and Additional Rent shall not be diminished during the repair
of such damage and Tenant shall be liable to Landlord for the cost and expense
of the repair and restoration of the Building caused thereby to the extent such
cost and expense is not covered by insurance proceeds.

E.   INSURANCE PROCEEDS. Notwithstanding anything herein to the contrary, if the
Premises or Building are damaged or destroyed and are not fully covered by the
insurance proceeds received by Landlord or if the holder of any indebtedness
secured by a mortgage or deed of trust covering the Premises requires that the
insurance proceeds be applied to such indebtedness, then in either case Landlord
shall have the right to terminate this Lease by delivering written notice of
termination to tenant within thirty (30) days after the date of notice to
Landlord that said damage or destruction is not fully covered by insurance or
such requirement is made by any such holder, as the case may be, whereupon this
Lease shall terminate.

F.   WAIVER. This Paragraph 24 shall be Tenant's sole and exclusive remedy in
the event of damage or destruction to the Premises or the Building. As a
material inducement to Landlord entering into this Lease. Tenant hereby waives
any rights it may have under Sections 1932, 1933(4), 1941 or 1942 of the Civil
Code of California with respect to any destruction of the Premises, Landlord's
obligation for tenantability of the Premises and Tenant's right to make repairs
and deduct the expenses of such repairs, or under any similar law, statute or
ordinance now or hereafter in effect.

G.   TENANT'S PERSONAL PROPERTY. In the event of any damage or destruction of
the Premises or the Building, under no circumstances shall Landlord be required
to repair any injury or damage to, or make any repairs to or replacements of,
Tenant's personal property.

                               25.  HOLDING OVER

Unless Landlord expressly consents in writing to Tenant's holding over, Tenant
shall be unlawfully and illegally in possession of the Premises, whether or not
Landlord accepts any rent from Tenant or any other person while Tenant remains
in possession of the Premises without Landlord's written consent. If Tenant
shall retain possession of the Premises or any portion thereof without
Landlord's consent following the expiration of this Lease or sooner termination
for any reason, then Tenant shall pay to Landlord for each day of such retention
double the amount of daily rental as of the last month prior to the date of
expiration or earlier termination. Tenant shall also indemnify, defend, protect
and hold Landlord harmless from any loss, liability or cost, including
consequential and incidental damages and reasonable attorneys' fees, incurred by
Landlord resulting from delay by Tenant in surrendering the Premises, including
without limitation, any claims made by the succeeding tenant founded on such
delay. Acceptance of Rent by Landlord following expiration or earlier
termination of this Lease, or following demand by Landlord for presentation of
the Premises, shall not constitute a renewal of this Lease, and nothing
contained in this Paragraph 25 shall waive Landlord's right of reentry or any
other right. Additionally, if upon expiration or earlier termination of this
Lease, or following demand by Landlord for possession of the Premises, Tenant
has not fulfilled its obligation with respect to repairs and cleanup of the
Premises or any other Tenant obligations as set forth in this Lease, then
Landlord shall have the right to perform any such obligations as it deems
necessary at Tenant's sole cost and expense, and any time required by Landlord
to complete such obligations shall be considered a period of holding over and
the terms of this Paragraph 25 shall apply. The provisions of this Paragraph 25
shall survive any expiration or earlier termination of this Lease.

                                  26.  DEFAULT

A.   EVENTS OF DEFAULT. The occurrence of any of the following shall constitute
an event of default on the part of Tenant:


                                       12



<PAGE>   13

     (1)  ABANDONMENT. Abandonment or vacation of the Premises for a continuous
     period in excess of five (5) days. Tenant waives any right to notice Tenant
     may have under Section 1951.3 of the Civil Code of California, the terms of
     this Paragraph 26.A. being deemed such notice to Tenant as required by said
     Section 1951.3.

     (2)  NONPAYMENT OF RENT.  Failure to pay ay installment of Rent or any
     other amount due and payable hereunder within three (3) days after the

     (3)  OTHER OBLIGATIONS.  Failure to perform any obligation, agreement or
     covenant under this Lease other than those matters specified in
     subparagraphs (1) and (2) of this Paragraph 26.A., such failure continuing
     for fifteen (15) days after written notice of such failure, as to which
     time is of the essence.

     creditors.

     the right to affirm this Lease and continue to perform the obligations of
     Tenant hereunder, such trustee or Tenant shall, in such time period as may
     be permitted by the bankruptcy court having jurisdiction, cure all defaults
     of Tenant hereunder outstanding as of the date of the affirmance of this

     (6)  RECEIVERSHIP.  The employment of a receiver to take possession of

     (8)  INSOLVENCY.  The admission by Tenant in writing of its inability to
     pay its debts as they become due.

B.   REMEDIES UPON DEFAULT.

     (1)  TERMINATION.  In the event of the occurrence of any event of default,
     Landlord shall have the right to give a written termination notice to
     Tenant, and on the date specified in such notice, Tenant's right to
     possession shall terminate, and this Lease shall terminate unless on or
     before such date all Rent in arrears and all costs and expenses incurred by
     or on behalf of Landlord hereunder shall have been paid by Tenant and all
     other events of default of this Lease by Tenant at the time existing shall
     have been fully remedied to the satisfaction of Landlord. At any time after
     such termination, Landlord may recover possession of the Premises or any
     part thereof and expel and remove therefrom Tenant and any other person
     occupying the same, including any subtenant or subtenants notwithstanding
     Landlord's consent to any sublease, by any lawful means, and again
     repossess and enjoy the Premises without prejudice to any of the remedies
     that Landlord may have under this Lease, or at law or equity by any reason
     of Tenant's default or of such termination. Landlord hereby reserves the
     right, but shall not  have the obligation, to recognize the continued
     possession of any subtenant. The delivery or surrender to Landlord by or on
     behalf of Tenant of keys, entry codes, or other means to bypass security
     at the Premises shall not terminate this Lease.

     (2)  CONTINUATION AFTER DEFAULT.  Even though an event of default may have
     occurred, this Lease shall continue in effect for so long as Landlord does
     not terminate Tenant's right to possession under Paragraph 26.B.(1) hereof,
     and Landlord may enforce all of Landlord's rights and remedies under this
     Lease and at law or in equity, including without limitation, the right to
     recover Rent as it becomes due, and Landlord, without terminating this
     Lease, may exercise all of the rights and remedies of a landlord under
     Section 1951.4 of the Civil Code of the State of California or any
     successor code section. Acts of maintenance, preservation or efforts to
     lease the Premises or the appointment of a receiver under application of
     Landlord to protect Landlord's interest under this Lease or other entry by
     Landlord upon the Premises shall not constitute an election to terminate
     Tenant's right to possession.

     (3)  INCREASED SECURITY DEPOSIT.  If Tenant is in default under Paragraph
     26.A.(2) hereof and such default remains uncured for five (5) days after
     such occurrence or such default occurs more than three times in any twelve
     (12) month period, Landlord may require that Tenant increase the Security
     Deposit to the amount of three times the current month's Rent at the time
     of the most recent default.


C.   DAMAGES AFTER DEFAULT. Should Landlord terminate this Lease pursuant to the
provisions of Paragraph 26.B.(1) hereof, Landlord shall have the rights and
remedies of a Landlord provided by Section 1951.2 of the Civil Code of the State
of California, or any successor code sections. Upon such termination, in
addition to any other rights and remedies to which Landlord may be entitled
under applicable law or at equity, Landlord shall be entitled to recover from
Tenant: (1) the worth at the time of award of the unpaid Rent and other amounts
which had been earned at the time of termination, (2) the worth at the time of
award of the amount by which the unpaid Rent and other amounts that would have
been earned after the date of termination until the time of award exceeds the
amount of such Rent loss that Tenant proves could have been reasonable avoided;
(3) the worth at the time of award of the amount by which the unpaid Rent and
other amounts for the balance of the Term after the time of award exceeds the
amount of such Rent loss that the Tenant proves could be reasonably avoided; and
(4) any other amount and court costs necessary to compensate Landlord for all
detriment proximately caused by Tenant's failure to perform Tenant's obligations
under this Lease or which, in the ordinary course of things, would be likely to
result therefrom. The "worth at the time of award" as used in (1) and (2) above
shall be computed at the Applicable Interest Rate (defined below). The "worth at
the time of award" as used in (3) above shall be computed by discounting such
amount at the Federal Discount Rate of the Federal Reserve Bank of San Francisco
at the time of award plus one percent (1%). If this Lease provides for any
periods during the Term during which Tenant is not required to pay Base Rent or
if Tenant otherwise receives a Rent concession, then upon the occurrence of an
event of default, Tenant shall owe to Landlord the full amount of such Base Rent
or value of such Rent concession, plus interest at the Applicable Interest Rate,
calculated from the date that such Base Rent concession would have been payable.

D.   LATE CHARGES. In addition to its other remedies, Landlord shall have the
right without notice or demand to add to the amount of any payment required to
be made by Tenant hereunder, and which is not paid and received by Landlord on
or before the first day of each calendar month, an amount equal to ten percent
(10%) of the delinquency for each month or portion thereof that the delinquency
remains outstanding to compensate Landlord for the loss of the use of the amount
not paid and the administrative costs caused by the delinquency, the parties
agreeing that Landlord's damage by virtue of such delinquencies would be
extremely difficult and impracticable to compare and the amount stated herein
represents a reasonable estimate thereof. Any waiver by Landlord of any late
charges or failure to claim the name shall not constitute a waiver of other late
charges or any other remedies available to Landlord.



Version 10.3                          13
<PAGE>   14
E.   INTEREST. Interest shall accrue on all sums not paid when due hereunder at
the lesser of eighteen percent (18%) per annum or the maximum interest rate
allowed by law ("Applicable Interest Rate") from the due date until paid.

F.   REMEDIES CUMULATIVE. All rights, privileges and elections or remedies of
the parties are cumulative and not alternative, to the extent permitted by law
and except as otherwise provided herein.

                                   27.  LIENS

Tenant shall at all times keep the Premises and the Project free from liens
arising out of or related to work or services performed, materials or supplies
furnished or obligations incurred by or on behalf of Tenant or in connection
with work made, suffered or done by or on behalf of Tenant in or on the Premises
or Project. If Tenant shall not, within ten (10) days following the imposition
of any such lien, cause the same to be released of record by payment or posting
of a proper bond, Landlord shall have, in addition to all other remedies
provided herein and by law, the right, but not the obligation, to cause the same
to be released by such means as Landlord shall deem proper, including payment
of the claim giving rise to such lien. All sums paid by Landlord on behalf of
Tenant and all expenses incurred by Landlord in connection therefor shall be
payable to Landlord by Tenant on demand with interest at the Applicable
Interest Rate as Additional Rent. Landlord shall have the right at all times to
post and keep posted on the Premises any notices permitted or required by law,
or which Landlord shall deem proper, for the protection of Landlord, the
Premises, the Project and any other party having an interest therein, from
mechanics' and materialmen's liens, and Tenant shall give landlord not less
than ten (10) business days prior written notice of the commencement of any
work in the Premises or Project which could lawfully give rise to a claim for
mechanics' or materialmen's liens to permit Landlord to post and record a
timely notice of non-responsibility, as Landlord may elect to proceed or as the
law may from time to time provide, for which purpose, if Landlord shall so
determine, Landlord may enter the Premises. Tenant shall not remove any such
notice posted by Landlord without Landlord's consent, and in any event not
before completion of the work which could lawfully give rise to a claim for
mechanics' or materialmen's liens.

                               28.  SUBSTITUTION

A.   At any time after execution of this Lease, Landlord may substitute for the
Premises other premises in the Project or owned by Landlord in the vicinity of
the Project (the "New Premises") upon not less than sixty (60) days prior
written notice, in which event the New Premises shall be deemed to be the
Premises for all purposes hereunder and this Lease shall be deemed modified
accordingly to reflect the new location and shall remain in full force and
effect as so modified, provided that:

     (1)  The New Premises shall be similar in area and in function for
     Tenant's purposes; and

     (2)  If Tenant is occupying the Premises at the time of such substitution,
     Landlord shall pay the expense of physically moving Tenant, Tenant's
     property and equipment to the New Premises and shall, at Landlord's sole
     cost, improve the New Premises with improvements substantially similar to
     those the Landlord has committed to provide or has provided in the
     Premises.

                           29.  TRANSFERS BY LANDLORD

In the event of a sale or conveyance by Landlord of the Building or a
foreclosure by any creditor of Landlord, the same shall operate to release
Landlord from any liability upon any of the covenants or conditions, express
or implied, herein contained in favor of Tenant, to the extent required to be
performed after the passing of title to Landlord's successor-in-interest. In
such event, Tenant agrees to look solely to the responsibility of the
successor-in-interest of Landlord under this Lease with respect to the
performance of the covenants and duties of "Landlord" to be performed after the
passing of title to Landlord's successor-in-interest. This Lease shall not be
affected by any such sale and Tenant agrees to attorn to the purchaser or
assignee. Landlord's successor(s)-in-interest shall not have liability to
Tenant with respect to the failure to perform any of the obligations of
"Landlord," to the extent required to be performed prior to the date such
successor(s)-in-interest became the owner of the Building.

              30.  RIGHT OF LANDLORD TO PERFORM TENANT'S COVENANTS

All covenants and agreements to be performed by Tenant under any of the terms
of this Lease shall be performed by Tenant at Tenant's sole cost and expense
and without any abatement of Rent. If Tenant shall fail to pay any sum of
money, other than Base Rent, required to be paid by Tenant hereunder or shall
fail to perform any other act on Tenant's part to be performed hereunder,
including Tenant's obligations under Paragraph 11 hereof, and such failure
shall continue for fifteen (15) days after notice thereof by Landlord, in
addition to the other rights and remedies of Landlord, Landlord may make any
such payment and perform any such act on Tenant's part. In the case of an
emergency, no prior notification by Landlord shall be required. Landlord may
take such actions without any obligation and without releasing Tenant from any
of Tenant's obligations. All sums so paid by Landlord and all incidental costs
incurred by Landlord and interest thereon at the Applicable Interest Rate, from
the date of payment by Landlord, shall be paid to Landlord on demand as
Additional Rent.

                                  31.  WAIVER

If either Landlord or Tenant waives the performance of any term, covenant or
condition contained in this Lease, such waiver shall not be deemed to be a
waiver of any subsequent breach of the same or any other term, covenant or
condition contained herein, or constitute a course of dealing contrary to the
expressed terms of this Lease. The acceptance of Rent by Landlord shall not
constitute a waiver of any preceding breach by Tenant of any term, covenant or
condition of this Lease, regardless of Landlord's knowledge of such preceding
breach at the time Landlord accepted such Rent. Failure by Landlord to enforce
any of the terms, covenants or conditions of this Lease for any length of time
shall not be deemed to waive or decrease the right of Landlord to insist
thereafter upon strict performance by Tenant. Waiver by Landlord of any term,
covenant or condition contained in this Lease may only be made by a written
document signed by Landlord, based upon full knowledge of the circumstances.

                                  32.  NOTICES

Each provision of this Lease or of any applicable governmental laws,
ordinances, regulations and other requirements with reference to sending,
mailing, or delivery of any notice or the making of any payment by Landlord or
Tenant to the other shall be deemed to be complied with when and if the
following steps are taken:

A.   RENT. All Rent and other payments required to be made by Tenant to
Landlord hereunder shall be payable to Landlord at Landlord's Remittance
Address set forth in the Basic Lease Information, or at such other address as
Landlord may specify from time to time by written notice delivered in
accordance herewith. Tenant's obligation to pay Rent and any other amounts to
Landlord under the terms of this Lease shall not be deemed satisfied until such
Rent and other amounts have been actually received by Landlord.

B.   OTHER. All notices, demands, consents and approvals which may or are
required to be given by either party to the other hereunder shall be in writing
and either personally delivered, sent by commercial overnight courier, mailed,
certified or registered, postage


                                       14
<PAGE>   15
prepaid or sent by facsimile with confirmed receipt (and with an original sent
by commercial overnight courier), and in each case addressed to the party to be
notified at the Notice Address for such party as specified in the Basic Lease
Information or to such other place as the party to be notified may from time to
time designate by at least fifteen (15) days notice to the notifying party.
Notices shall be deemed served upon receipt or refusal to accept delivery.
Tenant appoints as its agent to receive the service of all default notices and
notice of commencement of unlawful detainer proceedings the person in charge of
or apparently in charge of occupying the Premises at the time, and, if there is
no such person, then such service may be made by attaching the same on the main
entrance of the Premises.

C.   Required Notices.  Tenant shall immediately notify Landlord in writing of
any notice of a violation or a potential or alleged violation of any Regulation
that relates to the Premises or the Project, or of any inquiry, investigation,
enforcement or other actin that is instituted or threatened by any governmental
or regulatory agency against Tenant or any other occupant of the Premises, or
any claim that is instituted or threatened by any third party that relates to
the Premises or the Project.


                              33.  ATTORNEYS' FEES

If Landlord places the enforcement of this Lease, or any part thereof, or the
collection of any Rent due, or to become due hereunder, or recovery of
possession of the Premises in the hands of an attorney, Tenant shall pay to
Landlord, upon demand, Landlord's reasonable attorneys' fees and court costs,
whether incurred without trial, at trial, appeal or review. In any action which
Landlord or Tenant brings to enforce its respective rights hereunder, the
unsuccessful party shall pay all costs incurred by the prevailing party
including reasonable attorneys' fees, to be fixed by the court, and said costs
and attorneys' fees shall be a part of the judgment in said action.


                          34.  SUCCESSORS AND ASSIGNS

This Lease shall be binding upon and inure to the benefit of Landlord, its
successors and assigns, and shall be binding upon and inure to the benefit of
Tenant, its successors, and to the extent assignment is approved by Landlord as
provided hereunder, Tenant's assigns.


                               35.  FORCE MAJEURE

If performance by a party of any portion of this Lease is made impossible by any
prevention, delay, or stoppage caused by strikes, lockouts, labor disputes, acts
of God, inability to obtain services, labor, or materials or reasonable
substitutes for those items, government actions, civil commotions, fire or other
casualty, or other causes beyond the reasonable control of the party obligated
to perform, performance by that party for a period equal to the period of that
prevention, delay, or stoppage is excused. Tenant's obligation to pay Rent,
however, is not excused by this Paragraph 35.


                           36.  SURRENDER OF PREMISES

Tenant shall, upon expiration or sooner termination of this Lease, surrender the
Premises to Landlord in the same condition, reasonable wear and tear and
casualty excepted, as excepted, as existed on the date Tenant originally took
possession thereof, including, but not limited to, all interior walls cleaned,
all interior painted surfaces repainted in the original color, all holes in
walls repaired, all carpets shampooed and cleaned, and all floors cleaned, all
to the reasonable satisfaction of Landlord. Tenant shall remove all of its
debris from the Project. At or before the time of surrender, Tenant shall comply
with the terms of Paragraph 12.A. hereof with respect to Alterations to the
Premises and all other matters addressed in such Paragraph. If the Premises are
not so surrendered at the expiration or sooner termination of this Lease, the
provisions of Paragraph 25 hereof shall apply. All keys to the Premises or any
part thereof shall be surrendered to Landlord upon expiration or sooner
termination of the Term. Tenant shall give written notice to Landlord at least
thirty (30) days prior to vacating the Premises and shall meet with Landlord for
a joint inspection of the Premises at the time of vacating, but nothing
contained herein shall be construed as an extension of the Term or as a consent
by Landlord to any holding over by Tenant. In the event of Tenant's failure to
give such notice or participate in such joint inspection, Landlord's inspection
at or after Tenant's vacating the Premises shall conclusively be deemed correct
for purposes of determining Tenant's responsibility for repairs and restoration.
Any delay caused by Tenant's failure to carry out its obligations under this
Paragraph 36 beyond the term hereof, shall constitute unlawful and illegal
possession of Premises under paragraph 25 hereof.


                                  37. PARKING

     So long as Tenant is occupying the Premises, Tenant and Tenant's Parties
shall have the right to use up to the number of parking spaces, if any,
specified in the Basic Lease Information on an unreserved, nonexclusive, first
come, first served basis, for passenger-size automobiles, in the parking areas
in the Project designated from time to time by Landlord for use in common by
tenants of the Building.

     Tenant may request additional parking spaces from time to time and if
Landlord in its sole discretion agrees to make such additional spaces available
for use by Tenant, such spaces shall be provided on a month-to-month unreserved
and nonexclusive basis (unless otherwise agreed in writing by Landlord), and
subject to such parking charges as Landlord shall determine, and shall otherwise
be subject to such terms and conditions as Landlord may require.

     Tenant shall at all times comply and shall cause all Tenant's Parties and
visitors to comply with all Regulations and any rules and regulations
established from time to time by Landlord relating to parking at the Project,
including any keycard, sticker or other identification or entrance system, and
hours of operation, as applicable.

     Landlord shall have no liability for any damage to property or other items
located in the parking areas of the Project, nor for any personal injuries or
death arising out of the use of parking areas in the Project by Tenant or any
Tenant's Parties. Without limiting the foregoing, if Landlord arranges for the
parking areas to be operated by an independent contractor not affiliated with
Landlord, Tenant acknowledges that Landlord shall have no liability for claims
arising through acts or omissions of such independent contractor. In all events,
Tenant agrees to look first to its insurance carrier and to require that
Tenant's Parties look first to their respective insurance carriers for payment
of any loses sustained in connection with any use of the parking areas.

     Landlord reserves the right to assign specific spaces, and to reserve
spaces for visitors, small cars, disabled persons or for other tenants or
guests, and Tenant shall not park and shall not allow Tenant's Parties to park
in any such assigned or reserved spaces. Tenant may validate visitor parking by
such method as Landlord may approve, at the validation rate from time to time
generally applicable to visitor parking. Landlord also reserves the right to
alter, modify, relocate or close all or any portion of the parking areas in
order to make repairs or perform maintenance service, or to restripe or renovate
the parking areas, or if required by casualty, condemnation, act of God,
Regulations or for any other reason deemed reasonable by Landlord.

     Landlord reserves the right to impose a charge for parking at a future
time.

total Rent due nor any endorsement on any check or letter accompanying any
check or payment of Rent shall be deemed an accord and satisfaction of full

Landlord's right to recover the balance of such Rent or to pursue other
remedies. All offers by or on behalf of Tenant of accord and satisfaction are
hereby rejected in advance.

J.   EASEMENTS. Landlord may grant easements on the Project and dedicate for
public use portions of the Project without Tenant's consent; provided that no

this Lease or requested of Landlord, Landlord's consent, determination or
estimation shall be given or made solely by Landlord in Landlord's good faith

equitably claiming by, through or under Landlord, subject, nevertheless, to all
of the other terms and conditions of this Lease. Landlord shall not be liable
for any hindrance, interruption, interference or disturbance by other tenants or
third persons, nor shall Tenant be released from any obligations under this
Lease because of such hindrance, interruption, interference or disturbance.

P.   COUNTERPARTS. This Lease may be executed in any number of counterparts,
each of which shall be deemed an original.

                             RULES AND REGULATIONS

1.   Driveways, sidewalks, halls, passages, exits, entrances, elevators,
     escalators and stairways shall not be obstructed by tenants or used by
     tenants for any purpose other than for ingress to and egress from their
     respective premises. The driveways, sidewalks, halls, passages, exits,
     entrances, elevators and stairways are not for the use of the general
     public and Landlord shall in all cases retain the right to control and
     prevent access thereto by all persons whose presence, in the judgment of
     Landlord, shall be prejudicial to the safety, character, reputation and
     interests of the Building, the Project and its tenants, provided that
     nothing herein contained shall be construed to prevent such access to
     persons with whom any tenant normally deals in the ordinary course of such
     tenant's business unless such persons are engaged in illegal activities. No
     tenant, and no employees or invitees of any tenant, shall go upon the roof
     of any Building, except as authorized by Landlord. No tenant, and no
     employees or invitees of any tenant shall move any common area furniture
     without Landlord's consent.

2.   No sign, placard, banner, picture, name, advertisement or notice, visible
     from the exterior of the Premises or the Building or the common areas of
     the Building shall be inscribed, painted, affixed, installed or otherwise
     displayed by Tenant either on its Premises or any part of the Building or
     Project without the prior written consent of Landlord in Landlord's sole
     and absolute discretion. Landlord shall have the right to remove any such
     sign, placard, banner, picture, name, advertisement, or notice without
     notice to and at the expense of Tenant, which were installed or displayed
     in violation of this rule. If Landlord shall have given such consent to
     Tenant at any time, whether before or after the execution of Tenant's
     Lease, such consent shall in no way operate as a waiver or release of any
     of the provisions hereof or of the Lease, and shall be deemed to relate
     only to the particular sign, placard, banner, picture, name, advertisement,
     or notice so consented to by Landlord and shall not be construed as
     dispensing with the necessity of obtaining the specific written consent of
     Landlord with respect to any other such sign, placard, banner, picture,
     name, advertisement, or notice.

     All approved signs or lettering on doors and walls shall be printed,
     painted, affixed or inscribed at the expense of Tenant by a person or
     vendor approved by Landlord and shall be removed by Tenant at the time of
     vacancy at Tenant's expense.

3.   The directory of the Building or Project will be provided exclusively for
     the display of the name and location of tenants only and Landlord reserves
     the right to charge for the use thereof and to exclude any other names
     therefrom.

4.   No curtains, draperies, blinds, shutters, shades, screens or other
     coverings, awnings, hangings or decorations shall be attached to, hung or
     placed in, or used in connection with, any window or door on the Premises
     without the prior written consent of Landlord. In any event with the prior
     written consent of Landlord, all such items shall be installed inboard of
     Landlord's standard window covering and shall in no way be visible from the
     exterior of the Building. All electrical ceiling fixtures hung in offices
     or spaces along the perimeter of the Building must be fluorescent or of a
     quality, type, design, and bulb color approved by Landlord. No articles
     shall be placed or kept on the window sills so as to be visible from the
     exterior of the Building. No articles shall be placed against glass
     partitions or doors which Landlord considers unsightly from outside
     Tenant's Premises.

5.   Landlord reserves the right to exclude from the Building and the Project,
     between the hours of 6 p.m. and 8 a.m. and at all hours on Saturdays,
     Sundays and legal holidays, all persons who are not tenants or their
     accompanied guests in the Building. Each tenant shall be responsible for
     all persons for whom it allows to enter the Building or the Project and
     shall be liable to Landlord for all acts of such persons.

     Landlord and its agents shall not be liable for damages for any error
     concerning the admission to, or exclusion from, the Building or the Project
     of any person.

     During the continuance of any invasion, mob, riot, public excitement or
     other circumstance rendering such action advisable in Landlord's opinion,
     Landlord reserves the right (but shall not be obligated) to prevent access
     to the Building and the Project during the continuance of that event by any
     means it considers appropriate for the safety of tenants and protection of
     the Building, property in the Building and the Project.

6.   All cleaning and janitorial services for the Building and the Premises
     shall be provided exclusively through Landlord. Except with the written
     consent of Landlord, no person or persons other than those approved by
     Landlord shall be permitted to enter the Building for the purpose of
     cleaning the same. Tenant shall not cause any unnecessary labor by reason
     of Tenant's carelessness or indifference in the preservation of good order
     and cleanliness of its Premises. Landlord shall in no way be responsible to
     Tenant for any loss of property on the Premises, however occurring, or for
     any damage done to Tenant's property by the janitor or any other employee
     or any other person.

7.   Tenant shall see that all doors of its Premises are closed and securely
     locked and must observe strict care and caution that all water faucets or
     water apparatus, coffee pots or other heat-generating devices are entirely
     shut off before Tenant or its employees leave the Premises, and that all
     utilities shall likewise be carefully shut off, so as to prevent waste or
     damage. Tenant shall be responsible for any damage or injuries sustained by
     other tenants or occupants of the Building or Project or by Landlord for
     noncompliance with this rule. On multiple-tenancy floors, all tenants shall
     keep the door or doors to the Building corridors closed at all times except
     for ingress and egress.

8.   Tenant shall not use any method of heating or air-conditioning other than
     that supplied by Landlord. As more specifically provided in Tenant's lease
     of the Premises, Tenant shall not waste electricity, water or
     air-conditioning and agrees to cooperate fully with Landlord to assure the
     most effective operation of the Building's heating and air-conditioning,
     and shall refrain from attempting to adjust any controls other than room
     thermostats installed for Tenant's use.

9.   Landlord will furnish Tenant free of charge with two keys to each door in
     the Premises. Landlord may make a reasonable charge for any additional
     keys, and Tenant shall not make or have made additional keys. Tenant shall
     not alter any lock or access device or install a new or additional lock or
     access device or bolt on any door of its Premises, without the prior
     written consent of Landlord. If Landlord shall give its consent, Tenant
     shall in each case furnish Landlord with a key for any such lock. Tenant,
     upon the termination of its tenancy, shall deliver to Landlord the keys
     for all doors which have been furnished to Tenant, and in the event of
     loss of any keys so furnished, shall pay Landlord therefor.

     covenants, agreements and conditions of any lease of any premises in the
     Project.

36.  Landlord may waive any one or more of these Rules and Regulations for the
     benefit of any particular tenant or tenants, but no such waiver by
     Landlord shall be construed as a waiver of such Rules and Regulations in
     favor of any other tenant or tenants, nor prevent Landlord from thereafter
     enforcing any such Rules and Regulations against any or all tenants of the
     Building.

37.  Landlord reserves the right to make such other and reasonable rules and
     regulations as in its judgment may from time to time be needed for safety
     and security, for care and cleanliness of the Building and the Project and
     for the preservation of good order therein. Tenant agrees to abide by all
     such Rules and Regulations herein stated and any additional rules and
     regulations which are adopted.

               employment with INTERAD but not on the first anniversary of his

               first anniversary of his employment with INTERAD, multiplied by
               (y) 4.16% of the Ordinary Shares allotted to him pursuant to
               Section 7.1 above subject to the service of a

            option, each of Lior and Iftah shall have an option, exercisable for

      raise equity capital from the public by means of a public offering or by
      means of a private placement, all of the provisions in this Agreement or
      in INTERAD's Articles of Association shall be canceled to the extent that
      they conflict with such intention. Similarly, any provision that restricts
      the ability to perform any legal act with respect to a share shall be
      canceled.

15.   United States Operations

      The parties expect that it will be necessary to establish a United States
      headquarters operation to exploit the products to be developed by INTERAD.

      Board of Directors of INTERAD may determine.

16.   Reimbursement of Expenses and Wages

      16.1  Each of Lior and Iftah will be employed by INTERAD on a full-time
            basis in accordance with the respective employment agreements that

            1996. Lior and Iftah will receive a gross salary of NIS 17,000 until
            the repayment of the loan in accordance with Section 13 above or
            until such other time as shall be agreed between the parties. In
            addition, so long as Lior, Iftah and the other employees hired
            pursuant to Section 7.1 work in Jerusalem, INTERAD will make one car
            available for their use.

      16.2  BRB shall provide INTERAD with professional services. In
            consideration of the services to be provided by BRB to INTERAD,
            INTERAD shall pay BRB a monthly amount of NIS 17,000 and INTERAD
            shall bear the expenses incurred by BRB in providing the services.
            Until INTERAD raises capital through a public offering or private
            placement of securities to a party other than BRB, the payments to
            BRB pursuant to this section will accrue and shall be deemed part of
            BRB's shareholders loan under Section 13.1 above, to be repaid to
            BRB as specified in Section 13.2 above; thereafter, such amounts
            shall be paid on a current basis.

            If, pursuant to a resolution of the Board of Directors of INTERAD,
            any of the officers of BRB take an operative role in the day-to-day
            business of INTERAD, his remuneration will be determined by a
            special resolution of the shareholders of INTERAD.

      16.3  BRB shall use its best efforts to cause BRM to provide
            administrative and financial services, and to the extent feasible
            research and development services, to INTERAD. INTERAD shall
            reimburse BRM for such services on the basis of cost plus 15%.

     legal entity. Moreover, the parties covenant not to disclose and shall not
     in any way transfer to any person or entity any information in their

     thereafter.

     Kost Levary & Forar, certified public accountants, shall be appointed as
     the accountants of INTERAD.

     BRB shall have the right at any time to assign this Agreement to a company
     that is wholly controlled by BRB, to BRM or to any wholly-controlled
     subsidiary of BRM, but in any such case BRB shall remain liable for the
     obligations of the assignee under this Agreement.

THIS LOAN AND SECURITY AGREEMENT is entered into as of the above date, between
the above borrower(s) (jointly and severally, the "Borrower"), having its chief
executive office and principal place of business at the address shown above,
and TRANSAMERICA BUSINESS CREDIT CORPORATION, a Delaware corporation, ("TBCC")
having its principal office at 9399 West Higgins Road, Suite 600, Rosemont,
Illinois 60018 and having an office at 15260 Ventura Blvd., Suite 1240, Sherman
Oaks, CA 91403. The Schedule to this Agreement (the "Schedule") being signed
concurrently is an integral part of this Agreement. (Definitions of certain
terms used in this Agreement are set forth in Section 9 below.) The parties
agree as follows:

1.   LOANS.

     1.1.  Loans. TBCC, subject to the terms and conditions of this Agreement,
agrees to make loans (the "Loans") to Borrower, from time to time during the
period from the date of this Agreement to the Maturity Date set forth in the
Schedule, at Borrower's request, in an aggregate principal amount at any one
time outstanding not to exceed the Credit Limit shown on the Schedule. If at
any time the total outstanding Loans and other monetary Obligations exceed said
limit, Borrower shall repay the excess immediately without demand. Borrower
shall use the proceeds of all Loans solely for lawful general business purposes.

     1.2.  Due Date. The Loans, all accrued interest and all other monetary
Obligations shall be payable in full on the Maturity Date. Borrower may borrow,
repay and reborrow Loans (other than any Term Loans), in whole or in part, in
accordance with the terms of this Agreement.

     1.3.  Loan Account. TBCC shall maintain an account on its books in the name
of Borrower (the "Loan Account"). All Loans and advances made by TBCC to
Borrower or for Borrower's account and all other monetary Obligations will be
charged to the Loan Account. All amounts received by TBCC from Borrower or for
Borrower's account will be credited to the Loan Account. TBCC will send
Borrower a monthly statement reflecting the activity in the Loan Account, and
each such monthly statement shall be an account stated between Borrower and
TBCC and shall be final conclusive and binding absent manifest error.

     1.4.  Collection of Receivables. Borrower shall remit to TBCC all
Collections including all checks, drafts and other documents and instruments
evidencing remittances in payment (collectively referred to as "Items of
Payment") within one Business Day after receipt, in the same form as received,
with any necessary indorsements. For purposes of calculating interest due to
TBCC, credit will be given for Collections and all other proceeds of Collateral
and other payments to TBCC three Business Days after receipt of cleared funds.
For all purposes of this Agreement any cleared funds received by TBCC later
than 10:00 a.m. (California time) on any Business Day shall be deemed to have
been received on the following Business Day and any applicable interest or fee
shall continue to accrue. Borrower's Loan Account will be credited only with
the net amounts actually received in payment of Receivables, and such payments
shall be credited to the Obligations in such order as TBCC shall determine in
its discretion. Pending delivery to TBCC, Borrower will not commingle any Items
of Payment with any of its other funds or property, but will segregate them
from the other assets of Borrower and will hold them in trust and for the
account and as the property of TBCC. Borrower hereby agrees to endorse any
Items of Payment upon the request of TBCC.

     1.5.  Reserves. TBCC may, from time to time, in its Good Faith business
Judgment: (i) establish and modify reserves against Eligible Receivables and
Eligible Inventory, (ii) modify advance rates with respect to Eligible
Receivables and Eligible Inventory, (iii) modify the standards of eligibility
set forth in the definitions of Eligible Receivables and Eligible Inventory,
and (iv) establish reserves against available Loans.

     1.6.  Term.

Property, including withdrawal of any and all funds from any securities
accounts;

          (f)  Sell, assign and deliver the Receivables and other Collateral,

Documents by any available procedure, take possession of any or all of the
Collateral, with or without judicial process and enter any premises where any
Collateral may be located for the purpose of taking possession of or removing
the same.

          (h)  TBCC may bid or become a purchaser at any sale, free from any
right of redemption, which right is expressly waived by Borrower, if permitted
under applicable law. If notice of intended disposition of any Collateral is
required by law, it is agreed that ten days' notice shall constitute reasonable
notification. Borrower will assemble the Collateral and make it available at
such locations as TBCC may specify, whether at the premises of Borrower or
elsewhere, and will make available to TBCC the premises and facilities of
Borrower for the purpose of TBCC's taking possession of or removing the
Collateral or putting the Collateral in salable form.

          (i)  Borrower recognizes that TBCC may be unable to make a public sale
of any or all of the Investment Property, by reasons of prohibitions contained
in applicable securities laws or otherwise, and expressly agrees that a private
sale to a restricted group of purchasers for investment and not with a view to
any distribution thereof shall be considered a commercially reasonable sale.

     7.3  Receivables. Upon the occurrence and during the continuance of an
Event of Default, or at any time that TBCC believes in good faith that fraud
has occurred or that Borrower has failed to deliver the proceeds of Receivables
or other Collateral to TBCC as required by this Agreement or any other Loan
Document, TBCC may (i) settle or adjust disputes or claims directly with
account debtors for amounts and upon terms which it considers advisable, and
(ii) notify account debtors on the Receivables and other Collateral that the
Receivables and Collateral have been assigned to TBCC, and that payments in
respect thereof shall be made directly to TBCC. If an Event of Default has
occurred and is continuing or TBCC reasonably believes in good faith that fraud
has occurred, or that Borrower has failed to deliver the proceeds of
Receivables or other Collateral to TBCC as required by this Agreement or any
other Loan Document, Borrower hereby irrevocably authorizes and appoints TBCC,
or any Person TBCC may designate, as its attorney-in-fact, at Borrower's sole
cost and expense, to exercise, all of the following powers, which are coupled
with an interest and are irrevocable, until all of the Obligations have been
indefeasibly paid and satisfied in full in cash: (A) to receive, take, endorse,
sign, assign and deliver, all in the name of TBCC or Borrower, any and all
checks, notes, drafts, and other documents or instruments relating to the
Collateral; (B) to receive, open and dispose of all mail addressed to Borrower
and to notify postal authorities to change the address for delivery thereof to
such address as TBCC may designate; and (C) to take or bring, in the name of
TBCC or Borrower, all steps, actions, suits or proceedings deemed by TBCC
necessary or desirable to enforce or effect collection of Receivables and other
Collateral or file and sign Borrower's name on a proof of claim to bankruptcy or
similar document against any obligor of Borrower.

     7.4  Right of Setoff. In addition to all rights of offset that TBCC may
have under applicable law, upon the occurrence and during the continuance of any
Event of Default, and whether or not TBCC has made any demand or the Obligations
of Borrower have matured, TBCC shall have the right to appropriate and apply to
the payment of the Obligations of Borrower all deposits and other obligations
then or thereafter owing by TBCC to or for the credit or the account of
Borrower. In the event that TBCC exercises any of its rights under this
Section, TBCC shall provide notice to Borrower of such exercise, provided that
the failure to give such notice shall not affect the validity of the exercise of
such rights.

     7.5  License for Use of Software and Other Intellectual Property. After
the occurrence and during the continuance of an Event of Default, unless
expressly prohibited by any licensor thereof, TBCC is hereby granted a license
to use all computer software programs, data bases, processes, trademarks,
tradenames and materials used by Borrower in connection with its business or in
connection with the Collateral.

     7.6  No Marshalling; Deficiencies; Remedies Cumulative. The net cash
proceeds resulting from TBCC's exercise of any of its rights with respect to
Collateral, including any and all Collections (after deducting all of TBCC's
reasonable expenses related thereto), shall be applied by TBCC to such of the
Obligations in such order as TBCC shall elect in its sole and absolute
discretion, whether due or to become due. Borrower shall remain liable to TBCC
for any deficiencies and TBCC shall remit to Borrower or its successor or
assign, any surplus resulting therefrom. The remedies specified in this
Agreement are cumulative, may be exercised in such order and with respect to
such Collateral as TBCC may deem desirable and are not intended to be exclusive,
and the full or partial exercise of any of them shall not preclude the full or
partial exercise of any other available remedy under this Agreement, under any
other Loan Document, at equity or at law.

     7.7  Waivers. Borrower hereby waives any bonds, security or sureties
required by any statute, rule or any other law as an incident to any taking of
possession by TBCC of any Collateral. Borrower also waives any damages (direct,
consequential or otherwise) occasioned by the enforcement of TBCC's rights
under this Agreement or any other Loan Document including the taking of
possession of any

     7.8   Right to Make Payments. In the event that Borrower shall fail to
purchase or maintain insurance required hereunder, or to pay any tax,

permitted hereunder, or in the event that any Lien prohibited hereby shall not
be paid in full or discharged, or in the event that Borrower shall fail to
perform or comply with any other covenant, promise or obligation to TBCC
hereunder or under any other Loan Document . TBCC may (but shall not be required
to) perform, pay, satisfy, discharge or bond the same for the account of
Borrower, and all amounts so paid by TBCC shall be treated as a Loan hereunder
to Borrower and shall constitute part of the Obligations.

8. ASSIGNMENTS AND PARTICIPATIONS.

   8.1. Assignments. Borrower shall not assign this Agreement or any right or

first-priority, valid, perfected Lien. Without limiting the generality of the
foregoing, Borrower must be in compliance with all requirements of the Loan
Documents regarding registration with the U.S. Copyright Office of any
copyrightable software in order for any Receivable arising from any licensing of
such software to constitute an Eligible Receivable hereunder. Receivables owing
from one account debtor will not be deemed Eligible Receivables to the extent
they exceed 75% of the total eligible Receivables outstanding. In addition, if
more than 50% of the Receivables owing from an account debtor are outstanding
more than 90 days from their invoice date (without regard to unapplied credits)
or are otherwise not eligible Receivables, then all Receivables owing from that
account debtor will be deemed ineligible for borrowing. TBCC may, from time to
time, in its sole discretion, revise the Minimum Eligibility Requirements, upon
written notice to the Borrower.

litigation, investigation, claim or proceeding which arises out of or is related
to (A) Borrower, or this Agreement, any other Loan Document or the transactions
contemplated hereby or thereby, (B) any actual or proposed use by Borrower of

reasonable fees and disbursements of counsel incurred in connection with any
such litigation, investigation, claim or proceeding, (ii) any remedial or other

respect of this Agreement, any other Loan Document or any other document or
instrument now or hereafter executed and delivered in connection herewith,
collect the Obligations or otherwise administer this Agreement, foreclose or
otherwise realize upon the Collateral or any part thereof, prosecute actions
against, or defend actions by, account debtors; commence, intervene in, or
defend any action or proceeding; initiate any complaint to be relieved of the

enforcement of, execution upon or defense of any order, decree, award or
judgment. If and to the extent that the Obligations of Borrower hereunder are
unenforceable for any reason, Borrower hereby agrees to make the maximum
contribution to the payment and satisfaction of the Obligations which is
permissible under applicable law. Borrower's obligations under Section 2.4 and
this Section shall survive any termination of this Agreement and the other Loan

     10.8. Amendments and Waivers. Any provision of this Agreement or any other
Loan Document may be amended or waived if, but only if, such amendment or
waiver is in writing and signed by Borrower and TBCC and then any such
amendment or waiver shall be effective only to the extent set forth therein.
The failure of TBCC at any time or times to require Borrower to strictly comply
with any of the provisions of this Agreement or any other present or future
agreement between Borrower and TBCC shall not waive or diminish any right of
TBCC later to demand and receive strict compliance therewith. Any waiver of any
default shall not waive or affect any other default, whether prior or
subsequent, and whether or not similar. None of the provisions of this
Agreement or any other agreement now or in the future executed by Borrower and
delivered to TBCC shall be deemed to have been waived by any act or knowledge
of TBCC or its agents or employees, but only by a specific written waiver
signed by an authorized officer of TBCC and delivered to Borrower.

     10.9. Counterparts: Telecopied Signatures. This Agreement and any waiver
or amendment hereto may be executed in counterparts and by the parties hereto
in separate counterparts, each of which when so executed and delivered shall be
an original, but both of which shall together constitute one and the same
instrument. This Agreement and each of the other Loan Documents and any notices
given in connection herewith or therewith may be executed and delivered by
telecopier or other facsimile transmission all with the same force and effect as
if the same was a fully executed and delivered original manual counterpart.

     10.10. Severability. In case any provision in or obligation under this
Agreement or any other Loan Document shall be invalid, illegal or unenforceable
in any jurisdiction, the validity, legality and enforceability of the
remaining provisions or obligations, or of such provision or obligation in any
other jurisdiction, shall not in any way be affected or impaired thereby.

     10.11. Joint and Several Liability. If Borrower consists of more than one
Person, their liability shall be joint and several, and the compromise of any
claim with, or the release of, any Borrower shall not constitute a compromise
with, or a release of, any other Borrower.

     10.12. Maximum Rate. Notwithstanding anything to the contrary contained
elsewhere in this Agreement or in any other Loan Document, the parties hereto
hereby agree that all agreements between them under this Agreement and the other
Loan Documents, whether now existing or hereafter arising and whether written or
oral, are expressly limited so that in no contingency or event whatsoever shall
the amount paid, or agreed to be paid, to TBCC for the use, forbearance, or
detention of the money loaned to Borrower and evidenced hereby or thereby or for
the performance or payment of any covenant or obligation contained herein or
therein, exceed the maximum non-usurious interest rate, if any, that at any time
or from time to time may be contracted for, taken, reserved, charged or received
on the Obligations, under the laws of the State of Illinois (or the laws of any
other jurisdiction whose laws may be mandatorily applicable notwithstanding
other provisions of this Agreement and the other Loan Documents), or under
applicable federal laws which may presently or hereafter be in effect and which
allow a higher maximum non-usurious interest rate than under the laws of the
State of Illinois (or such other jurisdiction), in any case after taking into
account, to the extent permitted by applicable law, any and all relevant
payments or charges under this Agreement and the other Loan Documents executed
in connection herewith, and any available exemptions, exceptions and exclusions
(the "Highest Lawful Rate"). If due to any circumstance whatsoever, fulfillment
of any provisions of this Agreement or any of the other Loan Documents at the
time performance of such provision shall be due shall exceed the Highest Lawful
Rate, then, automatically, the obligation to be fulfilled shall be modified or
reduced to the extent necessary to limit such interest to the Highest Lawful
Rate, and if from any such circumstance TBCC should ever receive anything of
value deemed interest by applicable law which would exceed the Highest Lawful
Rate, such excessive interest shall be applied to the reduction of the principal
amount then outstanding hereunder or on account of any other then outstanding
Obligations and not to the payment of interest, or if such excessive interest
exceeds the principal unpaid balance then outstanding hereunder and such other
then

outstanding Obligations, such excess shall be refunded to Borrower. All sums
paid or agreed to be paid to TBCC for the use, forbearance, or detention of the
Obligations and other indebtedness of Borrower to TBCC shall, to the extent
permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full term of such indebtedness, until payment in full thereof, so
that the actual rate of interest on account of all such indebtedness does not
exceed the Highest Lawful Rate throughout the entire term of such indebtedness.
The terms and provisions of this Section shall control every other provision of
this Agreement, the other Loan Documents and all other agreements between the
parties hereto.


     10.13. Entire Agreement; Successors and Assigns. This Agreement and the
other Loan Documents constitute the entire agreement between the parties,
supersede any prior written and verbal agreements between them, and shall bind
and benefit the parties and their respective successors and permitted assigns.
There are no oral understandings, oral representations or oral agreements
between the parties which are not set forth in this Agreement or in other
written agreements signed by the parties in connection herewith. *

     *10.13A Confidentiality. In handling any confidential information TBCC
shall exercise the same degree of care that it exercises with respect to its own
proprietary information of the same types to maintain the confidentiality of any
non-public information thereby received or received pursuant to this Agreement
except that disclosure of such information may be made (i) to the subsidiaries
or affiliates of TBCC in connection with their present or prospective business
relations with Borrower, (ii) to prospective transferees or purchasers of any
interest in the Loans, provided that they have entered into a confidentiality
agreement with TBCC comparable to this Section, (iii) as required by law,
regulations, rule or order, subpoena, judicial order or similar order, (iv) as
may be required in connection with the examination, audit or similar
investigation of TBCC, and (v) as TBCC may deem appropriate in connection with
the exercise of any remedies hereunder. Confidential information hereunder shall
not include information that either: (a) is in the public domain or in the
knowledge or possession of TBCC when disclosed to TBCC, or becomes part of the
public domain after disclosure to TBCC through no fault of TBCC; or (b) is
disclosed to TBCC by a third party, provided TBCC does not have actual knowledge
that such third party is prohibited from disclosing such information.

     10.14. MUTUAL WAIVER OF JURY TRIAL. TBCC AND BORROWER EACH HEREBY WAIVE THE
RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT OF,
OR IN ANY WAY RELATING TO: (i) THIS AGREEMENT; OR (ii) ANY OTHER PRESENT OR
FUTURE INSTRUMENT OR AGREEMENT BETWEEN TBCC AND BORROWER; OR (iii) ANY CONDUCT,
ACTS OR OMISSIONS OF TBCC OR BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS,
EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH TBCC OR
BORROWER; IN EACH OF THE FOREGOING CASES, WHETHER SOUNDING IN CONTRACT OR TORT
OR OTHERWISE.

     Exchange Rights and shall be entitled to exercise all of the rights and
     powers of an owner with respect to the Exchange Right and the Automatic
     Exchange Rights, provided that the Trustee shall:

          (a)  hold the Exchange Rights and the Automatic Exchange Rights and
               the legal title thereto as trustee solely for the use and benefit
               of the Beneficiaries in accordance with the provisions of this
               Agreement; and

          (b)  except as specifically authorized by this Agreement, have no
               power or authority to exercise or otherwise deal in or with the
               Exchange Right or the Automatic Exchange Rights, and the Trustee
               shall not exercise any such rights for any purpose other than the
               purposes for which this Trust is created pursuant to this
               Agreement.

5.2  Legended Share Certificates. The Corporation will cause each certificate
     representing Exchangeable Shares to bear an appropriate legend notifying
     the Beneficiaries of:

          (a)  their right to instruct the Trustee with respect to the exercise
               of the Exchange Right in respect of the Exchangeable Shares held
               by a Beneficiary; and






<PAGE>   13
                                      -13-



     (b)  the Automatic Exchange Rights.

5.3  General Exercise of Exchange Right. the Exchange Rights shall be and
     remain vested in and exercised by the Trustee. Subject to section 7.15 of
     this Agreement, the Trustee shall exercise the Exchange Right only on the
     basis of written instructions received pursuant to this Article 5 from
     Beneficiaries entitled to instruct the Trustee as to the exercise thereof.
     If requested by BackWeb, the Trustee shall provide a copy of such
     instructions to BackWeb. To the extent that no instructions are received
     from a Beneficiary with respect to the Exchange Right, the Trustee shall
     not exercise or permit the exercise of the Exchange Right.

5.4  Purchase Price. The purchase price payable by BackWeb for each
     Exchangeable Share to be purchased by BackWeb under the Exchange Right
     shall be an amount per share equal to (a) the Current Market Price of a
     BackWeb Ordinary Share on the last Business Day prior to the day of
     closing of the purchase and sale of such Exchangeable Share under the
     Exchange Right plus (b) an additional amount equivalent to the full amount
     of all dividends declared and unpaid on each such Exchangeable Share and
     all dividends declared on BackWeb Ordinary Shares which have not been
     declared on such Exchangeable Shares in accordance with Section 3.1 of the
     Exchangeable Share Provisions (provided that if the record date for any
     such declared and unpaid dividends occurs on or after the day of closing
     of such purchase and sale the purchase price shall not include such
     additional amount equivalent to such declared and unpaid dividends). In
     connection with each exercise of the Exchange Right, BackWeb will provide
     to the Trustee an Officer's Certificate setting forth the calculation of
     the purchase price for each Exchangeable Share. The purchase price for
     each such Exchangeable Share so purchased may be satisfied only by BackWeb
     delivering or causing to be delivered to the Trustee, on behalf of the
     relevant Beneficiary, (subject to compliance with applicable securities
     laws), one BackWeb Ordinary Share and a cheque for the amount of the
     purchase price (less any part thereof satisfied by the issuance of a
     BackWeb Ordinary Share) without interest. The Trustee shall be entitled to
     rely and be fully protected in so relying and acting upon such Officer's
     Certificate.

5.5  Exercise Instructions. Subject to the terms and conditions herein set
     forth, a Beneficiary shall be entitled, upon the occurrence and during the
     continuance of an Insolvency Event, to instruct the Trustee to exercise the
     Exchange Right with respect to all or any part of the Exchangeable Shares
     registered in the name of such Beneficiary on the books of the Corporation.
     To cause the exercise of the Exchange Right by the Trustee, the Beneficiary
     shall deliver to the Trustee, in person or by certified or registered mail,
     at its principal corporate trust office in Toronto, Ontario or at such
     other places in Canada as the Trustee may from time to time designate by
     written notice to the Beneficiaries, the certificates representing the
     Exchangeable Shares which such Beneficiary desires BackWeb to purchase,
     duly endorsed in blank, and accompanied by such other documents and
     instruments as may be required to effect a transfer of Exchangeable Shares
     under the



<PAGE>   14
                                      -14-



     Business Corporations Act (Ontario) and the by-laws of the Corporation and
     such additional documents and instruments as the Trustee may reasonably
     require together with (a) a duly completed form of notice of exercise of
     the Exchange Right (in the form attached as Schedule "A" to this
     Agreement), contained on the reverse of or attached to the Exchangeable
     Share certificates, stating (i) that the Beneficiary thereby instructs the
     Trustee to exercise the Exchange Right so as to require BackWeb to
     purchase from the Beneficiary the number of Exchangeable Shares specified
     therein, (ii) that such Beneficiary has good title to and owns all such
     Exchangeable Shares to be acquired by BackWeb free and clear of all liens,
     claims and encumbrances, (iii) the names in which the certificates
     representing BackWeb Ordinary Shares deliverable in connection with the
     exercise of the Exchange Right and cheques for the balance of the purchase
     price, if any, are to be issued, and (iv) the names and addresses of the
     persons to whom such new certificates and cheques for the balance of the
     purchase price, if any, should be delivered and (b) payment (or evidence
     satisfactory to the Trustee, the Corporation and BackWeb of payment) of
     the taxes (if any) payable as contemplated by section 5.8 of this
     Agreement. If only a part of the Exchangeable Shares represented by any
     certificate or certificates delivered to the Trustee are to be purchased
     by BackWeb under the Exchange Right, a new certificate for the balance of
     such Exchangeable Shares shall be issued by the Corporation to the holder
     at the expense of the Corporation.

5.6  DELIVERY OF BACKWEB ORDINARY SHARES; EFFECT OF EXERCISE.

     (a)  Promptly after receipt of the certificates representing the
          Exchangeable Shares which the Beneficiary desires BackWeb to
          purchase under the Exchange Right together with such documents and
          instruments of transfer and a duly completed form of notice of
          exercise of the Exchange Right (and payment of taxes, if any, or
          evidence thereof), duly endorsed for transfer to BackWeb, the
          Trustee shall provide notice (substantially in the form of Schedule
          "B" to this Agreement) to BackWeb and the Corporation of its receipt
          of the same, which notice to BackWeb and the Corporation shall
          constitute exercise of the Exchange Right by the Trustee on behalf of
          the holder of such Exchangeable Shares, and BackWeb shall immediately
          thereafter deliver or cause to be delivered to the Trustee, for
          delivery to the Beneficiary of such Exchangeable Shares (or to such
          other persons, if any, properly designated by such Beneficiary),
          (subject to compliance with applicable securities laws) the
          certificates for the number of BackWeb Ordinary Shares deliverable in
          connection with the exercise of the Exchange Right, which shares
          shall be duly issued as fully paid and non-assessable and shall be
          free and clear of any lien, claim or encumbrance, and cheques for the
          total purchase price therefor (less any part thereof satisfied by the
          issuance of BackWeb Ordinary Shares).

     (b)  Immediately upon the giving of notice by the Trustee to BackWeb and
          the Corporation of the exercise of the Exchange Right, as provided in
          this Section 5.6 but subject to section 5.13 of this Agreement
          regarding withholding tax, the

<PAGE>   15
                                      -15-


          closing of the transaction of purchase and sale contemplated by the
          Exchange Right shall be deemed to have occurred, and the Beneficiary
          of such Exchangeable Shares shall be deemed to have transferred to
          BackWeb all of its right, title and interest in and to such
          Exchangeable Shares and in the related interest in the Trust Estate
          and shall cease to be a holder of such Exchangeable Shares and shall
          not be entitled to exercise any of the rights of a holder in respect
          thereof, other than the right to receive his proportionate part of the
          total purchase price therefor, provided that if the requisite number
          of BackWeb Ordinary Shares (together with a cheque for the total
          purchase price therefor (less any part thereof satisfied by the
          issuance of BackWeb Ordinary Shares)) is not allotted, issued an
          delivered by BackWeb to the Trustee for delivery to such Beneficiary
          (or to such other persons, if any, properly designated by such
          Beneficiary), within five Business Days of the date of the giving of
          such notice by the Trustee, the rights of the Beneficiary shall remain
          unaffected until such BackWeb Ordinary Shares are so allotted, issued
          and delivered by BackWeb and/or any such cheque is so delivered and
          paid, as applicable. Concurrently with such Beneficiary ceasing to be
          a holder of Exchangeable Shares, the Beneficiary shall be considered
          and deemed for all purposes to be the holder of BackWeb Ordinary
          Shares delivered to it pursuant to the Exchange Right.

5.7  Exercise of Exchange Right Subsequent to Retraction. In the event that a
     Beneficiary has exercised its right under Article 6 of the Exchangeable
     Share Provisions to require the Corporation to redeem any or all of the
     Exchangeable Shares held by the Beneficiary (the "Retracted Shares") and is
     notified by the Corporation pursuant to Section 6.6 of the Exchangeable
     Shares Provisions that the Corporation will not be permitted as a result of
     solvency requirements of applicable law to redeem all such Retracted
     Shares, and provided that BackWeb shall not have exercised the Retraction
     Call Right with respect to the Retracted Shares and that the Beneficiary
     has not revoked the retraction request delivered by the Beneficiary to the
     Corporation pursuant to Section 6.1 of the Exchangeable Share Provisions,
     the retraction request will constitute and will be deemed to constitute
     notice from the Beneficiary to the Trustee instructing the Trustee to
     exercise the Exchange Right with respect to those Retracted Shares which
     the Corporation is unable to redeem. In any such event, the Corporation
     hereby agrees with the Trustee and in favour of the Beneficiary immediately
     to notify the Trustee of such prohibition against the Corporation redeeming
     all of the Retracted Shares and immediately to forward or cause to be
     forwarded to the Trustee all relevant materials delivered by the
     Beneficiary to the Corporation (including without limitation a copy of the
     retraction request delivered pursuant to Section 6.1 of the Exchangeable
     Share Provisions) in connection with such proposed redemption of the
     Retracted Shares and the Trustee will thereupon exercise the Exchange Right
     with respect to the Retracted Shares that the Corporation is not permitted
     to redeem and will require BackWeb to purchase such shares in accordance
     with the provisions of this Article 5.

5.8  Stamp or Other Transfer Taxes. Upon any sale of Exchangeable Shares to
     BackWeb pursuant to the Exchange Rights or the Automatic Exchange Rights,
     the share certificate or certificates representing BackWeb Ordinary Shares
     to be delivered in connection with the payment of the total purchase price
     therefor shall be issued in the name of the Beneficiary of the Exchangeable
     Shares so sold or in such name as such Beneficiary may otherwise direct in
     writing without charge to the holder of the Exchangeable Shares so sold;
     provided, however, that such Beneficiary (a) shall pay (and neither
     BackWeb, the Corporation nor the Trustee shall be required to pay) any
     documentary, stamp, transfer or other taxes that may be payable in respect
     of any transfer involved in the issuance or delivery of such shares to a
     person other than such Beneficiary or (b) shall have established to the
     satisfaction of the Trustee, BackWeb and the Corporation that such taxes,
     if any, have been paid.

5.9  Notice of Insolvency Event. Immediately upon the occurrence of an
     Insolvency Event or any event which with the giving of notice or the
     passage of time or both would be an Insolvency Event, the Corporation and
     BackWeb shall give written notice thereof to the Trustee. As soon as
     practicable after receiving notice from the Corporation and BackWeb or
     from any other person of the occurrence of an Insolvency Event, the
     Trustee will mail or cause to be mailed to each Beneficiary, at the
     expense of BackWeb, a notice of such Insolvency Event, which notice shall
     contain a brief statement of the right of the Beneficiaries with respect
     to the Exchange Right. It shall be a condition precedent to the Trustee's
     obligation to mail a Beneficiary a notice of Insolvency Event that the
     Corporation  prepare such notice and provide the Trustee with a sufficient
     quantity in a timely fashion.

5.10 Qualification of BackWeb Ordinary Shares. BackWeb represents and warrants
     that it has taken all actions and done all things as are necessary or
     desirable under any Canadian or Israeli federal, provincial or state law
     or regulation or pursuant to the rules and regulations of any regulatory
     or any other legal requirement (collectively, the "APPLICABLE LAWS") as
     they exist on the date hereof and will in good faith expeditiously take
     all such actions and do all such things as are necessary or desirable under
     Applicable Laws as they may exist in the future to cause the BackWeb
     Ordinary Shares to be issued and delivered pursuant to the Exchangeable
     Share Provisions, the Exchange Right or the Automatic Exchange Rights
     (other than compliance with Applicable Laws relating to the ability of
     holders to freely trade the BackWeb Ordinary Shares, as to which no
     representation is given. To the extent that holders of Exchangeable Shares
     have exercised registration rights in respect of BackWeb Ordinary Shares
     issuable in accordance with the Exchangeable Share Provisions, BackWeb
     will in good faith expeditiously take all such actions and do all things
     as are necessary or desirable to cause all BackWeb Ordinary Shares to be
     delivered pursuant to the Exchangeable Share Provisions, the Exchange
     Right or the Automatic Exchange Rights to be listed, quoted or posted for
     trading on all stock exchanges and quotation systems, if any, on which
     outstanding BackWeb Ordinary Shares are listed, quoted or posted for
     trading at such time.

5.11 Reservation of BackWeb Ordinary Shares. BackWeb hereby represents,
     warrants and covenants that it has irrevocably reserved for issuance and
     will at all times keep available, free from pre-emptive and other rights,
     out of its authorized and unissued capital stock such number of BackWeb
     Ordinary Shares (a) as is equal to the sum of (i) the number of
     Exchangeable Shares issued and outstanding from time to time and (ii) the
     number of Exchangeable Shares issuable upon the exercise of all rights to
     acquire Exchangeable Shares outstanding from time to time and (b) as are
     now and may hereafter be required to enable and permit the Corporation and
     BackWeb to meet their respective obligations hereunder, under the Support
     Agreement, under the Exchangeable Share Provisions and under any other
     security or commitment pursuant to which BackWeb may now or hereafter be
     required to issue BackWeb Ordinary Shares.

5.12 Automatic Exchange on Liquidation of BackWeb.

          (a)  BackWeb will give the Trustee notice of each of the following
               events at the time set forth below:

               (i)  in the event of any determination by the Board of Directors
                    of BackWeb to institute voluntary liquidation, dissolution
                    or winding up proceedings with respect to BackWeb or to
                    effect any other distribution of assets of BackWeb among
                    its shareholders for the purpose of winding up its affairs,
                    at least 60 days prior to the proposed effective date of
                    such liquidation, dissolution, winding up or other
                    distribution; and

               (ii) immediately, upon the earlier of (A) receipt by BackWeb of
                    notice of and (B) BackWeb otherwise becoming aware of any
                    threatened or instituted claim, suit, petition or other
                    proceedings with respect to the involuntary liquidation,
                    dissolution or winding-up of BackWeb or to effect any other
                    distribution of assets of BackWeb among its shareholders
                    for the purpose of winding up its affairs.

          (b)  immediately following receipt by the Trustee from BackWeb of
               notice of any event (a "Liquidation Event") contemplated by
               section 5.12(a)(i) or 5.12(a)(ii) above, the Trustee will give
               notice thereof to the Beneficiaries. Such notice shall include a
               brief description of the automatic exchange of Exchangeable
               Shares for BackWeb Ordinary Shares provided for in section
               5.12(c).

          (c)  In order that the Beneficiaries will be able to participate on a
               pro rata basis with the holders of BackWeb Ordinary Shares in
               the distribution of assets of BackWeb in connection with a
               Liquidation Event, on the fifth Business Day prior to the
               effective date (the "Liquidation Event Effective Date")
<PAGE>   18
                                      -18-


               of a Liquidation Event all of the then outstanding Exchangeable
               Shares shall be automatically exchanged for BackWeb Ordinary
               Shares. To effect such automatic exchange, BackWeb shall purchase
               each Exchangeable Share outstanding on the fifth Business Day
               prior to the Liquidation Event Effective Date and held by
               Beneficiaries, and each Beneficiary shall sell the Exchangeable
               Shares held by it at such time, for a purchase price per
               Exchangeable Share equal to (a) the Current Market Price of a
               BackWeb Ordinary Share on the fifth Business Day prior to the
               Liquidation Event Effective Date, which shall be satisfied in
               full by BackWeb delivering or causing to be delivered to the
               Beneficiary one BackWeb Ordinary Share, plus (b) an additional
               amount equivalent to the full amount of all dividends declared
               and unpaid on each such Exchangeable Share and all dividends
               declared on BackWeb Ordinary Shares which have not been declared
               on such Exchangeable Shares in accordance with section 3.1 of the
               Exchangeable Share Provisions (provided that if the record date
               for any such declared and unpaid dividends occurs on or after the
               day of closing of such purchase and sale the purchase price shall
               not include such additional amount equivalent to such declared
               and unpaid dividends). In connection with such automatic
               exchange, BackWeb will provide to the Trustee an Officer's
               Certificate setting forth the calculation of the purchase price
               for each Exchangeable Share. The Trustee shall be entitled to
               rely and be fully protected in so relying and acting upon such
               Officer's Certificate.

          (d)  On the fifth Business Day prior to the Liquidation Event
               Effective Date, the closing of the transaction of purchase and
               sale contemplated by the automatic exchange of Exchangeable
               Shares for BackWeb Ordinary Shares shall be deemed to have
               occurred, and each Beneficiary shall be deemed to have
               transferred to BackWeb all of the Beneficiary's right, title and
               interest in and to its Exchangeable Shares and the related
               interest in the Trust Estate and shall cease to be a holder of
               such Exchangeable Shares and BackWeb shall deliver or cause to be
               delivered to the Beneficiary BackWeb Ordinary Shares deliverable
               upon the automatic exchange of Exchangeable Shares for BackWeb
               Ordinary Shares and shall deliver to the Trustee for delivery to
               the Beneficiary a cheque for the balance, if any, of the total
               purchase price for such Exchangeable Shares. Concurrently with
               such Beneficiary ceasing to be a holder of Exchangeable Shares,
               the Beneficiary shall be considered and deemed for all purposes
               to be the holder of BackWeb Ordinary Shares issued to it pursuant
               to the automatic exchange of Exchangeable Shares for BackWeb
               Ordinary Shares and the certificates held by the Beneficiary
               previously representing the Exchangeable Shares exchanged by the
               Beneficiary with BackWeb pursuant to such automatic exchange
               shall thereafter be deemed to represent BackWeb Ordinary Shares
               delivered to the Beneficiary by BackWeb pursuant to such
               automatic
<PAGE>   19

                                      -19-

               exchange. Upon the request of a Beneficiary and the surrender by
               the Beneficiary of Exchangeable Share certificates deemed to
               represent BackWeb Ordinary Shares, duly endorsed in blank and
               accompanied by such instruments of transfer as BackWeb may
               reasonably require, BackWeb shall deliver or cause to be
               delivered to the Beneficiary certificates representing BackWeb
               Ordinary Shares of which the Beneficiary is the holder.

     5.13 Withholding Rights. BackWeb and the Trustee shall be entitled to
          deduct and withhold from the consideration otherwise payable pursuant
          to this Agreement to any holder of Exchangeable Shares such amounts
          as BackWeb or the Trustee is required or permitted to deduct and
          withhold with respect to the making of such payment under the Income
          Tax Act (Canada) or any provision of provincial tax law. To the
          extent that amounts are so withheld, such withheld amounts shall be
          treated for all purposes of this Agreement as having been paid to the
          holder of the shares in respect of which such deduction and
          withholding was made, provided that such withheld amounts are
          actually remitted to the appropriate taxing authority. To the extent
          that the amount so required or permitted to be deducted or withheld
          from any payment to a holder exceeds the cash portion of the
          consideration otherwise payable to the holder, BackWeb or the trustee
          is hereby authorized to sell or otherwise dispose of at fair market
          value such portion of the consideration as is necessary to provide
          sufficient funds to BackWeb or the Trustee, as the case may be, in
          order to enable it to comply with such deduction or withholding
          requirement and shall account to the relevant holder for any balance
          of such sale proceeds.

          If, upon the occurrence of an Insolvency Event, a non-Canadian
          resident Beneficiary instructs the Trustee to exercise the Exchange
          Right, BackWeb shall provide the Trustee, in cash, with sufficient
          funds to satisfy any withholding taxes applicable in connection with
          the sale of such Beneficiary's Exchangeable Shares to BackWeb
          otherwise such exchange shall not have occurred or be deemed to have
          occurred. The "fair market value" of the BackWeb Ordinary Shares at a
          particular date shall, for the purposes of calculating any such
          applicable withholding taxes, shall be the Current Market Price or
          shall be determined by such other method of valuation which has been
          recommended or suggested by Revenue Canada as providing a satisfactory
          assessment of such fair market value. Prior to making any distribution
          to holders of Exchangeable Shares, BackWeb or the Corporation, as the
          case may be, shall ensure that the Trustee has access to sufficient
          funds (by directly providing, if necessary, such funds to the Trustee)
          to enable the Trustee to comply with any applicable withholding taxes
          in connection with such distribution.

                                   ARTICLE 7

     the Trustee under this Agreement, in its capacity as trustee of the Trust,
     shall include:

          (a)  the receipt and holding of the Voting Share from BackWeb as
               trustee for and on behalf of the Beneficiaries in accordance
               with the provisions of this Agreement;

          (b)  granting proxies and distributing materials to Beneficiaries as
               provided in this Agreement;

          (c)  voting the Beneficiary Votes in accordance with the provisions
               of this Agreement;

          (d)  receiving the grant of the Exchange Right and the Automatic
               Exchange Rights from BackWeb as trustee for and on behalf of the
               Beneficiaries in accordance with the provisions of this
               Agreement;

          (e)  exercising the Exchange Right and enforcing the benefit of the
               Automatic Exchange Rights, in each case in accordance with the
               provisions of this Agreement, and in connection therewith
               receiving from Beneficiaries Exchangeable Shares and other
               requisite documents and distributing to such Beneficiaries
               BackWeb Ordinary Shares and cheques, if any, to which such
               Beneficiaries are entitled upon the exercise of the Exchange
               Right or pursuant to the Automatic Exchange Rights, as the case
               may be;

          (f)  holding title to the Trust Estate;

          (g)  investing any moneys forming, from time to time, a part of the
               Trust Estate as provided in section 7.11 of this Agreement;

<PAGE>   21
                                      -21-

          (h)  taking action on its own initiative or at the direction of a
               Beneficiary or Beneficiaries to enforce the obligations of
               BackWeb under this Agreement; and

          (i)  taking such other actions and doing such other things as are
               specifically provided in this Agreement.

     In the exercise of such rights, powers and authorities, the Trustee shall
     have (and is granted) such incidental and additional rights, powers and
     authority not in conflict with any of the provisions of this Agreement as
     may be necessary, appropriate or desirable to effect the purpose of the
     Trust. Any exercise of such rights, powers and authorities by the Trustee
     shall be final, conclusive and binding upon all persons affected thereby
     including the parties to this Agreement and the Beneficiaries. For greater
     certainty, the Trustee shall have no duties or liabilities except those
     which are expressly set forth in this Agreement. In particular, the
     Trustee will have no liability or responsibility arising under any
     agreement or instrument, including the Acquisition Agreement, the
     Exchangeable Share Provisions or any other agreement or instrument
     referred to in this Agreement, to which the Trustee is not a party and
     shall not be bound by any notice of a claim or demand with respect thereto.

     The Trustee in exercising its rights, powers, duties and authorities
     hereunder shall act honestly and in good faith with a view to the best
     interests of the Beneficiaries and shall exercise the care, diligence and
     skill that a reasonably prudent person would exercise in comparable
     circumstances.

7.2  NO CONFLICT OF INTEREST. The Trustee represents to the Corporation and
     BackWeb that at the date of execution and delivery of this Agreement there
     exists no material conflict of interest between its role as Trustee under
     this Agreement and its role in any other capacity. The Trustee shall,
     within 90 days after it becomes aware that such a material conflict of
     interest exists, either eliminate such material conflict of interest or
     resign in the manner and with the effect specified in Article 10 of this
     Agreement. If, notwithstanding the foregoing provisions of this section
     7.2, the Trustee has such a material conflict of interest, the validity
     and enforceability of this Agreement shall not be affected in any manner
     whatsoever by reason only of the existence of such material conflict of
     interest. If the Trustee contravenes the foregoing provisions of this
     section 7.2, any interested party may apply to the Ontario Court (General
     Division) for an order that the Trustee be replaced as trustee under this
     Agreement.

7.3  DEALING WITH TRANSFER AGENTS, REGISTRARS, ETC. The Corporation and BackWeb
     irrevocably authorize the Trustee, from time to time, to:

<PAGE>   22
                                      -22-


            (a)   consult, communicate and otherwise deal with the respective
                  registrars and transfer agents, and with any such subsequent
                  registrar or transfer agent, of the Exchangeable Shares and
                  BackWeb Ordinary Shares; and

            (b)   requisition, from time to time, (i) from any such registrar or
                  transfer agent any information readily available from the
                  records maintained by it which the Trustee may reasonably
                  require for the discharge of its duties and responsibilities
                  under this Agreement, and (ii) from the registrar or transfer
                  agent of BackWeb Ordinary Shares, and any subsequent registrar
                  or transfer agent of such shares, the share certificates
                  issuable upon the exercise from time to time of the Exchange
                  Right and pursuant to the Automatic Exchange Rights in the
                  manner specified in Article 5 of this Agreement.

      The Corporation and BackWeb irrevocably authorize their respective
      registrars and transfer agents to comply with all such requests. BackWeb
      covenants that it will supply BackWeb's transfer agent with duly executed
      share certificates for the purpose of completing the exercise from time to
      time of the Exchange Right and the Automatic Exchange Rights, in each case
      pursuant to Article 5 of this Agreement.

7.4   Books and Records. The Trustee shall keep available for inspection by
      BackWeb and the Corporation, at the Trustee's principal corporate trust
      office in Toronto, Ontario, correct and complete books and records of
      account relating to the Trustee's actions under this Agreement, including
      without limitation all information relating to mailings and instructions
      to and from Beneficiaries and all transactions pursuant to the Exchange
      Right and the Automatic Exchange Rights. On or before March 31, 1998, and
      on or before March 31 in every year thereafter, so long as the Voting
      Share is on deposit with the Trustee, the Trustee shall transmit to
      BackWeb and the Corporation a brief report, dated as of the preceding
      December 31, with respect to:

            (a)   the property and funds comprising the Trust Estate as of that
                  date;

            (b)   the number of exercises of the Exchange Right, if any, and the
                  aggregate number of Exchangeable Shares received by the
                  Trustee on behalf of the Beneficiaries in consideration of
                  the issue and delivery by BackWeb of BackWeb Ordinary Shares
                  in connection with the Exchange Right, during the calendar
                  year ended on such date; and

            (c)   all other actions taken by the Trustee in the performance of
                  its duties under this Agreement which it had not previously
                  reported.

7.5   Income Tax Returns and Reports. The Trustee shall, if required under the
      Income Tax Act (Canada) or any provincial law or if advised by BackWeb or
      the Corporation, prepare
<PAGE>   23
                                      -23-



      and file on behalf of the Trust the appropriate income tax returns and any
      other returns or reports as may be required by applicable law or pursuant
      to the rules and regulations of any securities exchange or other trading
      system through which the Exchangeable Shares are traded and, in connection
      therewith and, without limiting the generality of section 7.10 of this
      Agreement, may obtain the advice and assistance of such experts as the
      Trustee may consider necessary or advisable. If requested by the Trustee,
      BackWeb shall retain such experts for purposes of providing such advice
      and assistance.

7.6   Indemnification Prior to Certain Actions by Trustee. The Trustee shall
      exercise any or all of the rights, duties, powers or authorities vested in
      it by this Agreement at the request, order or direction of any Beneficiary
      upon such Beneficiary furnishing to the Trustee reasonable funding,
      security and indemnity against the costs, expenses and liabilities which
      may be incurred by the Trustee, provided that no Beneficiary shall be
      obligated to furnish to the Trustee any such funding, security or
      indemnity in connection with the exercise by the Trustee of any of its
      rights, duties, powers and authorities with respect to the Voting Share
      pursuant to Article 4 of this Agreement, subject to section 7.15 of this
      Agreement, and with respect to the Exchange Right pursuant to Article 5 of
      this Agreement, subject to section 7.15 of this Agreement, and with
      respect to the Automatic Exchange Rights pursuant to Article 5 of this
      Agreement. None of the provisions contained in this Agreement shall
      require the Trustee to expend or risk its own funds or otherwise incur
      financial liability in the exercise of any of its rights, powers, duties
      or authorities unless funded, given security and indemnified as provided
      in this Agreement.

7.7   Actions by Beneficiaries. No Beneficiary shall have the right to institute
      any action, suit or proceeding or to exercise any other remedy authorized
      by this Agreement for the purpose of enforcing any of its rights or for
      the execution of any trust or power hereunder unless the Beneficiary has
      requested the Trustee to take or institute such action, suit or proceeding
      and furnished the Trustee with the funding, security and indemnity
      referred to in section 7.6 of this Agreement and the Trustee shall have
      failed to act within a reasonable time thereafter. In such case, but not
      otherwise, the Beneficiary shall be entitled to take proceedings in any
      court of competent jurisdiction such as the Trustee might have taken; it
      being understood and intended that no one or more Beneficiaries shall have
      any right in any manner whatsoever to affect, disturb or prejudice the
      rights hereby created by any such action, or to enforce any rights
      hereunder or under the Voting Rights, the Exchange Right or the Automatic
      Exchange Rights except subject to the conditions and in the manner
      provided of this Agreement, and that all powers and trusts under this
      Agreement shall be exercised and all proceedings at law shall be
      instituted, had and maintained by the Trustee, except only as provided of
      this Agreement, and in any event for the equal benefit of all
      Beneficiaries.

7.8   Reliance upon Declarations. The Trustee shall not be considered to be in
      contravention of any of its rights, powers, duties and authorities
      hereunder if it acts and relies in good faith upon lists, mailing labels,
      notices, statutory declarations, certificates, opinions,
<PAGE>   24
                                      -24-

     reports or other papers or documents furnished pursuant to the provisions
     hereof or required by the Trustees to be furnished to it in the exercise
     of its rights, powers, duties and authorities hereunder.

7.9  EVIDENCE AND AUTHORITY TO TRUSTEE. To the extent the Corporation and/or
     BackWeb are required to furnish to the Trustee evidence of compliance with
     the conditions provided for in this Agreement relating to any action or
     step required or permitted to be taken by the Corporation and/or BackWeb
     or the Trustee under this Agreement or as a result of any obligation
     imposed under this Agreement, including, without limitation, in respect of
     the Voting Rights or the Exchange Right or the Automatic Exchange Rights,
     and the taking of any other action to be taken by the Trustee at the
     request of or on the application of the Corporation and/or BackWeb, such
     evidence shall consist of an Officer's Certificate of the Corporation
     and/or BackWeb, as the case may be, or a statutory declaration or a
     certificate made by persons entitled to sign an Officer's Certificate
     stating that any such condition has been complied with in accordance with
     the terms of this Agreement.

     Whenever such evidence relates to a matter other than the Voting Rights or
     the Exchange Right or the Automatic Exchange Rights and except as
     otherwise specifically provided herein, such evidence may consist of a
     report or opinion of any solicitor, auditor, accountant, appraiser,
     valuer, engineer or other expert or any other person whose qualifications
     give authority to a statement made by him, provided that if such report or
     opinion is furnished by a director, officer or employee of the Corporation
     and/or BackWeb it shall be in the form of an Officer's Certificate or a
     statutory declaration.

     Each statutory declaration, certificate, opinion or report furnished to
     the Trustee as evidence of compliance with a condition provided for in
     this Agreement or as the Trustee may otherwise request shall include a
     statement by the person giving the evidence:

          (a)  declaring that he has read and understands the provisions of this
               Agreement relating to the condition in question;

               certificate, statement or opinion; and

          (c)  declaring that he has made such examination or investigation as
               he believes is necessary to enable him to make the statements or

7.10    Experts, Advisors and Agents. The Trustee may:

                (a)  in relation to these presents, act and rely on the opinion
                     or advice of or information obtained from any solicitor,
                     auditor, accountant, appraiser, valuer, engineer or other
                     expert, whether retained by the Trustee or by the
                     Corporation and/or BackWeb or otherwise, and may employ
                     such assistants as may be necessary to the proper discharge
                     of its powers and duties and determination of its rights
                     under this Agreement and may pay proper and reasonable
                     compensation for all such legal and other advice or
                     assistance; and

                (b)  employ such agents and other assistants as it may
                     reasonably require for the proper discharge of its powers
                     and duties under this Agreement, and may pay reasonable
                     remuneration for all services performed for it (and shall
                     be entitled to receive reasonable remuneration for all
                     services performed by it) and compensation for all
                     disbursements, costs and expenses made or incurred by it in
                     the discharge of its duties under this Agreement and in the
                     management of the Trust.

7.11    Investment of Moneys Held By Trustee. Unless otherwise provided in this
        Agreement, any moneys held by or on behalf of the Trustee shall, unless
        otherwise directed in writing by the Corporation, be deposited in an
        interest bearing account at any chartered bank in Canada, including Bank
        of Montreal. At the end of each calendar year during which the Trustee
        shall have held monies in trust in accordance with this Section 7.11,
        the Trustee shall file on behalf of the Trust or, if required by law,
        shall issue to the Beneficiaries of the Trust, all appropriate forms
        under the Income Tax Act (Canada) in respect of any interest earned on
        such monies and to the extent such income is allocated to the
        Beneficiaries, it shall be allocated in proportions equivalent to the
        Beneficiaries' respective percentage ownership of the Exchangeable
        Shares outstanding at the relevant allocation date. The Corporation
        shall provide or cause to be provided such information as the Trustee
        may require in respect of the Beneficiaries' ownership of Exchangeable
        Shares.

7.12    Trustee Not Required to Give Security. The Trustee shall not be required
        to give any bond or security in respect of the execution of the trusts,
        rights, duties, powers and authorities of this Agreement or otherwise in
        respect of the premises.

7.13    Trustee Not Bound to Act on Corporation's Request. Except as in this
        Agreement otherwise specifically provided, the Trustee shall not be
        bound to act in accordance with any direction or request of the
        Corporation and/or BackWeb or of the directors thereof until a duly
        authenticated copy of the instrument or resolution containing such
        direction or request shall have been delivered to the Trustee, and the
        Trustee shall be empowered to act and rely upon and be protected in so
        acting and relying upon any such copy purporting to be authenticated and
        believed by the Trustee to be genuine.

7.14  Authority to Carry on Business. The Trustee represents to the Corporation
      and BackWeb that at the date of execution and delivery by it of this
      Agreement it is authorized to carry on the business of a trust company in
      the Province of Ontario but if, notwithstanding the provisions of this
      section 7.14, it ceases to be so authorized to carry on business, the
      validity and enforceability of this Agreement and the Voting Rights, the
      Exchange Right and the Automatic Exchange Rights shall not be affected in
      any manner whatsoever by reason only of such event but the Trustee shall,
      within 90 days after ceasing to be authorized to carry on the business of
      a trust company in the Province of Ontario, either become so authorized
      or resign in the manner and with the effect specified in Article 10 of
      this Agreement.

7.15  Conflicting Claims. If conflicting claims or demands are made or asserted
      with respect to any interest of any Beneficiary in any Exchangeable
      Shares, including any disagreement between the heirs, representatives,
      successors or assigns succeeding to all or any part of the interest of
      any Beneficiary in any Exchangeable Shares resulting in conflicting
      claims or demands being made in connection with such interest, then the
      Trustee shall be entitled, at its sole discretion, to refuse to recognize
      or to comply with any such claim or demand. In so refusing, the Trustee
      may elect not to exercise any Voting Rights, Exchange Right or Automatic
      Exchange Rights subject to such conflicting claims or demands and, in so
      doing, the Trustee shall not be or become liable to any person on account
      of such election or its failure or refusal to comply with any such
      conflicting claims or demands. The Trustee shall be entitled to continue
      to refrain from acting and to refuse to act until:

            (a)   the rights of all adverse claimants with respect to the
                  Voting Rights, Exchange Right or Automatic Exchange Rights
                  subject to such conflicting claims or demands have been
                  adjudicated by a final judgment of a court of competent
                  jurisdiction; or

            (b)   all differences with respect to the Voting Rights, Exchange
                  Right or Automatic Exchange Rights subject to such
                  conflicting claims or demands have been conclusively settled
                  by a valid written agreement binding on all such adverse
                  claimants, and the Trustee shall have been furnished with an
                  executed copy of such agreement.

      If the Trustee elects to recognize any claim or comply with any demand
      made by any such adverse claimant, it may in its discretion require such
      claimant to furnish such surety bond or other security satisfactory to the
      Trustee as it shall deem appropriate fully to indemnify it as between all
      conflicting claims or demands.

7.16  Acceptance of Trust. The Trustee hereby accepts the Trust created and
      provided for by and in this Agreement and agrees to perform the same upon
      the terms and conditions herein set forth and to hold all rights,

      in trust for the various persons who shall from time to time be
      Beneficiaries, subject to all the terms and conditions set forth in this
      Agreement.

7.17  Notice to Trustee. The Trustee shall not be bound to give any notice or
      do or take any act, action or proceeding by virtue of the powers
      conferred on it hereby unless and until it shall have been required so to
      do under the terms of this Agreement; nor shall the Trustee be required
      to take notice of, be deemed to have actual or constructive notice or
      knowledge of any matter under this Agreement, or take any action in
      connection with any notice of any BackWeb Meeting or the seeking of any
      BackWeb Consent or any prohibition of the Corporation against redeeming
      any Retracted Shares as set out in section 5.7 of this Agreement or of
      any Insolvency Event or Liquidation Event as set out in sections 5.9 and
      5.12 of this Agreement, respectively, (collectively, a "Notice Event"),
      unless and until notified in writing of such Notice Event desired to be
      brought to the attention of the Trustee and in the absence of any such
      notice the Trustee may for all purposes of this Agreement conclusively
      assume that no such Notice Event has occurred.

7.18  Merger or Consolidation of Trustee. Any corporation into or with which
      the Trustee may be merged or consolidated or amalgamated, or any
      corporation resulting therefrom to which the Trustee shall be a party, or
      any corporation succeeding to the trust business of the Trustee shall be
      the successor to the Trustee under this Agreement without any further act
      on its part or any of the parties hereto, provided that such corporation
      would be eligible for appointment as a successor trustee under the
      provisions of this Agreement.

7.19  No Personal Liability. In the exercise of the powers, authorities or
      discretion conferred upon the Trustee under this Agreement, the Trustee
      is and shall be conclusively deemed to be acting as trustee of the Trust
      and shall not be subject to any personal liability for any of the
      liabilities, obligations, claims, demands, judgements, costs or expenses
      against or with respect to the Trust.

7.20  Incumbency Certificate. Each of the Corporation and BackWeb shall file
      with the Trustee a certificate of incumbency setting forth the names of
      the individuals authorized to give instructions, directions or other
      instruments to the Trustee ("Authorized Persons"), together with specimen
      signatures of such persons, and the Trustee shall be entitled to rely on
      the latest certificate of incumbency filed with it unless it receives
      notice, in accordance with section 7.11, of a change in Authorized
      Persons with updated specimen signature.

                                  COMPENSATION

8.1  Fees and Expenses of the Trustee. BackWeb and the Corporation jointly and
     severally agree to pay to the Trustee reasonable compensation for all of
     the services rendered by it under this Agreement and will reimburse the
     Trustee for all reasonable expenses (including taxes and the fees paid or
     to be paid by the Trustee pursuant to section 7.10) and disbursements,
     including the cost and expense of any suit or litigation of any character
     and any proceedings before any governmental agency reasonably incurred by
     the Trustee in connection with its rights and duties under this Agreement;
     provided that BackWeb and the Corporation shall have no obligation to
     reimburse the Trustee for any expenses or disbursements paid, incurred or
     suffered by the Trustee in any suit or litigation in which the Trustee is
     determined to have acted fraudulently or with gross negligence or wilful
     misconduct.


                                   ARTICLE 9
                  INDEMNIFICATION AND LIMITATION OF LIABILITY

9.1  Indemnification of the Trustee. BackWeb and the Corporation jointly and
     severally agree to indemnify and hold harmless the Trustee and each of its
     directors, officers, employees and agents appointed and acting in
     accordance with this Agreement (collectively, the "Indemnified Parties")
     against all claims, losses, damages, costs, taxes, penalties, interest,
     fines and reasonable expenses (including expenses of the Trustee's legal
     counsel on a solicitor and its own client basis) which, without fraud,
     gross negligence or wilful misconduct on the part of such Indemnified
     Party, may be paid, incurred or suffered by the Indemnified Party by
     reason of or as a result of the Trustee's acceptance or administration of
     the Trust, any act, error or omission by the Trustee in carrying out its
     duties and responsibilities set forth in this Agreement, the exercise of
     any power, authority or discretion pertaining thereto, or any written or
     oral instructions delivered to the Trustee by BackWeb or the Corporation
     pursuant hereto including, for greater certainty, any obligations or
     liability under applicable income tax legislation arising as a result of
     the Trustee being the owner of the Voting Share, Exchange Right and
     Automatic Exchange Right. In no case shall BackWeb or the Corporation be
     liable under this indemnity for any claim against any of the Indemnified
     Parties unless BackWeb and the Corporation shall be notified by the
     Trustee of the written assertion of a claim or of any action commenced
     against the Indemnified Parties, promptly after any of the Indemnified
     Parties shall have received any such written assertion of a claim or shall
     have been served with a summons or other first legal process giving
     information as to the nature and basis of the claim. Subject to (ii),
     below, BackWeb and the Corporation shall be entitled to participate at
     their own expense in the defence and, if BackWeb or the Corporation so
     elect at any time after receipt of such notice, either of them may assume
     the defence of any suit brought to enforce any such claim. The Trustee
     shall have the right to employ separate counsel in any such suit and
     participate in the defence thereof but the fees and


<PAGE>   29
                                      -29-


     expenses of such counsel shall be at the expense of the Trustee unless; (i)
     the employment of such counsel has been authorized by BackWeb or the
     Corporation; or (ii) the named parties to any such suit include both the
     Trustee and BackWeb or the Corporation and the Trustee shall have been
     advised by counsel acceptable to BackWeb or the Corporation that there may
     be one or more legal defenses available to the Trustee which are different
     from or in addition to those available to BackWeb or the Corporation (in
     which case BackWeb and the Corporation shall not have the right to assume
     the defense of such suit on behalf of the Trustee but shall be liable to
     pay the reasonable fees and expenses of counsel for the Trustee). This
     indemnity shall survive the termination of this Agreement or the
     resignation or replacement of the Trustee.

9.2  Limitation of Liability. The Trustee shall not be held liable for any loss
     which may occur by reason of depreciation of the value of any part of the
     Trust Estate pursuant to this Agreement, except to the extent that such
     loss is attributable to the fraud, gross negligence or wilful misconduct on
     the part of the Trustee.

                                   ARTICLE 10
                               CHANGE OF TRUSTEE

10.1 Resignation. The Trustee, or any trustee hereafter appointed, may at any
     time resign by giving written notice of such resignation to BackWeb and the
     Corporation specifying the date on which it desires to resign, provided
     that such notice shall never be given less than 30 days before such desired
     resignation date unless BackWeb and the Corporation otherwise agree and
     provided further that such resignation shall not take effect until the date
     of the appointment of a successor trustee and the acceptance of such
     appointment by the successor trustee. Upon receiving such notice of
     resignation, BackWeb and the Corporation shall promptly appoint a successor
     trustee by written instrument in duplicate, one copy of which shall be
     delivered to the resigning trustee and one copy to the successor trustee.


10.2 Removal. The Trustee, or any trustee hereafter appointed, may be removed at
     any time on 30 days' prior notice by written instrument executed by BackWeb
     and the Corporation, in duplicate, one copy of which shall be delivered to
     the trustee so removed and one copy to the successor trustee.

     In the event that a successor trustee has not been appointed at the time
     the notice period for the Trustee's resignation or removal expires, the
     Trustee, the Corporation, BackWeb or any Beneficiary may apply to a court
     of competent jurisdiction for the appointment of a successor to the Trustee
     and such appointment of a successor by such court shall not require the
     approval of the Beneficiaries.


10.3 Successor Trustee. Any successor trustee appointed as provided under this
     Agreement shall execute, acknowledge and deliver to BackWeb and the
     Corporation and to its
<PAGE>   30
                                      -30-


     predecessor trustee an instrument accepting such appointment. Thereupon the
     resignation or removal of the predecessor trustee shall become effective
     and such successor trustee, without any further act, deed or conveyance,
     shall become vested with all the rights, powers, duties and obligations of
     its predecessor under this Agreement, with like effect as if originally
     named as trustee in this Agreement. However, on the written request of
     BackWeb and the Corporation or of the successor trustee, the trustee
     ceasing to act shall, upon payment of any amounts then due it pursuant to
     the provisions of this Agreement, execute and deliver an instrument
     transferring to such successor trustee all the rights and powers of the
     trustee ceasing to act. Upon the request of any such successor trustee,
     BackWeb, the Corporation and such predecessor trustee shall execute any and
     all instruments in writing for more fully and certainly vesting in and
     confirming to such successor trustee all such rights and powers.

10.4 Notice of Successor Trustee. Upon acceptance of appointment by a successor
     trustee as provided in this Agreement, BackWeb and the Corporation shall
     cause to be mailed notice of the succession of such trustee under this
     Agreement to each Beneficiary specified in the List. If BackWeb or the
     Corporation shall fail to cause such notice to be mailed within 10 days
     after acceptance of appointment by the successor trustee, the successor
     trustee shall cause such notice to be mailed at the expense of BackWeb and
     the Corporation.

                                   ARTICLE 11
                               BACKWEB SUCCESSORS

11.1 Certain Requirements in Respect of Combination, etc. BackWeb shall not
     enter into any transaction (whether by way of reconstruction,
     reorganization, consolidation, merger, transfer, sale, lease or otherwise)
     whereby all or substantially all of its undertaking, property and assets
     would become the property of any other person or, in the case of a merger,
     of the continuing corporation resulting therefrom unless, but may-do so if:

          (a)  such other person or continuing corporation is a duly
               incorporated corporation (a "BackWeb Successor");

          (b)  BackWeb Successor, by operation of law, becomes, without more,
               bound by the terms and provisions of this Agreement or, if not so
               bound, executes, prior to or contemporaneously with the
               consummation of such transaction an Agreement supplemental to
               this Agreement and such other instruments (if any) as are
               satisfactory to the Trustee and in the opinion of legal counsel
               to the Trustee are necessary or advisable to evidence the
               assumption by BackWeb Successor of liability for all moneys
               payable and property deliverable under this Agreement and the
               covenant of such BackWeb Successor to pay and deliver or cause to
               be delivered the same

<PAGE>   31
                                      -31-

               and its agreement to observe and perform all the covenants and
               obligations of BackWeb under this Agreement; and

          (c)  such transaction shall, to the satisfaction of the Trustee and
               in the opinion of legal counsel to the Trustee, be upon such
               terms as substantially to preserve and not to impair in any
               material respect any of the rights, duties, powers and
               authorities of the Trustee or of the Beneficiaries under this
               Agreement.

11.2  Vesting of Powers in Successor. Whenever the conditions of section 11.1 of
      this Agreement have been duly observed and performed, the Trustee, if
      required, by section 11.1 of this Agreement, BackWeb Successor and the
      Corporation shall execute and deliver the supplemental Agreement
      provided for in Article 12 and thereupon BackWeb Successor shall possess
      and from time to time may exercise each and every right and power of
      BackWeb under this Agreement in the name of BackWeb or otherwise and
      any act or proceeding by any provision of this Agreement required to be
      done or performed by the board of directors of BackWeb or any officers
      of BackWeb may be done and performed with like force and effect by the
      directors or officers of such BackWeb Successor.

11.3  Wholly-Owned Subsidiaries. Nothing in this Agreement shall be construed
      as preventing the amalgamation or merger of any wholly-owned subsidiary
      of BackWeb with or into BackWeb or the winding-up, liquidation or
      dissolution of any wholly-owned subsidiary of BackWeb provided that all
      of the assets of such subsidiary are transferred to BackWeb or another
      wholly-owned subsidiary of BackWeb and any such transactions are
      expressly permitted by this Article 11.

                  AMENDMENTS AND SUPPLEMENTAL TRUST AGREEMENTS

             and its counsel, having in mind the best interests of the

             Directors of each of the Corporation and BackWeb shall be of the
             opinion that such changes or corrections will not be prejudicial to

      that it shall apply with full force and effect, mutatis mutandis, to all

      Shares or both are so changed and the parties hereto shall execute and
      deliver a supplemental Agreement giving effect to and evidencing such
      necessary amendments and modifications.

                      THE SECURITIES ACT OF 1933, AS AMENDED. SUCH SHARES MAY

                      REGISTRATION OR UNLESS THE COMPANY RECEIVES AN OPINION OF
                      COUNSEL REASONABLY ACCEPTABLE TO IT STATING THAT SUCH SALE
                      OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS
                      DELIVERY REQUIREMENTS OF

                      SAID ACT. COPIES OF THE AGREEMENTS COVERING THE PURCHASE
                      OF THESE SHARES AND RESTRICTING THEIR TRANSFER MAY BE
                      OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER
                      OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE
                      COMPANY AT THE PRINCIPAL EXECUTIVE OFFICES OF THE
                      COMPANY."

               Each Purchaser consents to the Company or BackWeb Canada, as the
case may be, making a notation on its records and giving instructions to any
transfer agent of the Preferred, the Exchangeable Shares or the Conversion Stock
in order to implement the restrictions on transfer established in this
Registration.

        4.     NOTICE OF PROPOSED TRANSFERS. The holder of each certificate
representing Restricted Securities by acceptance thereof agrees to comply in all
respects with the provisions of this Section 4. Prior to any proposed sale,
assignment, transfer or pledge of any Restricted Securities (other than (a) a
transfer not involving a change in beneficial ownership (which shall be deemed
to include without limitation a transfer between and among affiliates), (b) in
transactions involving the distribution without consideration of Restricted
Securities by any of the Purchasers to any of its partners, or retired partners,
or to the estate of any of its partners or retired partners, or a transfer to
one or more affiliated partnerships managed by it, so long as each such
transferee agrees in writing to be bound by the terms of this Agreement or (c)
the exchange of any Exchangeable Shares for Ordinary Shares), unless there is in
effect a registration statement under the Securities Act covering the proposed
transfer, the holder thereof shall give written notice to the Company of such
holder's intention to effect such transfer, sale, assignment or pledge. Each
such notice shall describe the manner and circumstances of the proposed
transfer, sale, assignment or pledge in sufficient detail, and shall be
accompanied, at such holder's expense by either (a) an unqualified written
opinion of legal counsel addressed to the Company, to the effect that the
proposed transfer of the Restricted Securities may be effected without
registration under the Securities Act, or (b) a "no action" letter from the
Commission to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such
Restricted Securities shall be entitled to transfer such Restricted Securities
in accordance with the terms of the notice delivered by the holder to the
Company. Each certificate evidencing the Restricted Securities transferred as
above provided shall bear, except if such transfer is made pursuant to Rule 144,
the appropriate restrictive legend set forth in Section 3 above, except that
such certificate shall not bear such restrictive legend if in the opinion of
counsel for such holder and the Company such legend is not required in order to
establish compliance with any provision of the Securities Act.

        5.     REQUESTED REGISTRATION.

               5.1    Notice of Registration; Registration. In case the Company
shall receive from Initiating Holders or Exchangeable Share Initiating Holders,
as the case may be, a written request that the Company effect any registration,
qualification or compliance (other than a registration on Form F-3 or any
successor form) with respect to (a) Registrable Securities that, as of the date
of the request, have



                                       -7-
<PAGE>   8



an aggregate market value of at least $15 million or (b) such Registrable
Securities represent at least 10% of the then outstanding Ordinary Shares of the
Company, the Company will:

                             (i)    promptly give written notice of the proposed
registration to all other Holders; and

                             (ii)   as soon as practicable, use its best efforts
to effect such registration, qualification or compliance (including, without
limitation, the execution of an undertaking to file post-effective amendments,
appropriate qualification under applicable blue sky or other state securities
laws and appropriate compliance with applicable regulations issued under the
Securities Act) as may be so requested and as would permit or facilitate the
sale and distribution of all or such portion of such Registrable Securities as
are specified in such request, together with all or such portion of the
Registrable Securities of any Holder or Holders joining in such request as are
specified in a written request given within fifteen (15) days after receipt of
such written notice from the Company, provided, however, that the Company shall
not be obligated to take any action to effect any such registration,
qualification or compliance pursuant to this Section 5:

                                    (1)    In any particular jurisdiction in
which the Company would be required to execute a general consent to service of
process in effecting such registration, qualification or compliance unless the
Company is already subject to service in such jurisdiction and except as may be
required by the Securities Act;

                                    (2)    Prior to the earlier of (a) five (5)
years following December 26, 1997, or (b) six months after the effective date of
the registration statement pertaining to the first underwritten firm commitment
public offering of securities of the Company for its own account (other than a
registration relating solely to a Commission Rule 145 transaction or a
registration relating solely to employee benefit plans);

                                    (3)    (i) In the case of a demand made by
Initiating Holders, if the Company has previously effected two (2) such
registrations of Preferred (and Ordinary Shares issued upon conversion thereof)
such registrations have been declared or ordered effective and the securities
offered pursuant to such registrations have been sold and (ii) in the case of a
demand made by the Exchangeable Share Initiating Holders, if the Company has
previously effected one (1) such registration of Exchangeable Shares (and
Ordinary Shares issued upon conversion thereof) and such registration has been
declared or ordered effective and the securities offered pursuant to such
registration has been sold.

                                    (4)    If at the time of the request to
register Registrable Securities the Company gives notice within thirty (30) days
of such request that it is engaged or has fixed plans to engage within thirty
(30) days of the time of the request in a firmly underwritten registered public
offering in which the Holders may include Registrable Securities pursuant to
Section 5, 6 or 7 hereof.

                                    (5)    Within 180 days after the effective
date of any other registration effected pursuant to this Section 5.1.



                                       -8-
<PAGE>   9



               Subject to the foregoing clauses (1) through (5) and to Section
5.3, the Company shall file a registration statement covering the Registrable
Securities so requested to be registered as soon as practicable after receipt of
the request of the Initiating Holders or the Exchangeable Share Initiating
Holders, as the case may be.

               5.2    Underwriting.

                      (a)    If the Initiating Holders or the Exchangeable Share
Initiating Holders, as the case may be, intend to distribute the Registrable
Securities covered by their request by means of an underwriting, they shall so
advise the Company as a part of their request made pursuant to Section 5 and the
Company shall include such information in the written notice referred to in
Section 5.1. The right of any Holder to registration pursuant to Section 5 shall
be conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent requested (unless otherwise mutually agreed by a majority in interest of
the Initiating Holders or the Exchangeable Share Initiating Holders, as the case
may be, and such Holder) as provided herein.

                      (b)    The Company shall (together with all Holders
proposing to distribute their securities through such underwriting) enter into
an underwriting agreement in customary form with the Underwriter selected for
such underwriting by a majority in interest of the Initiating Holders or the
Exchangeable Share Initiating Holders, as the case may be. If any Holder
disapproves of the terms of the underwriting, such person may elect to withdraw
therefrom by written notice to the Company, the Underwriter and the Initiating
Holders or the Exchangeable Share Initiating Holders, as the case may be. The
Registrable Securities and/or other securities so withdrawn from such
underwriting shall also be withdrawn from such registration; provided, however,
that, if by the withdrawal of such Registrable Securities a greater number of
Registrable Securities held by other Holders may be included in such
registration (up to the maximum of any limitation imposed by the underwriters),
then the Company shall offer to all Holders who have included Registrable
Securities in the registration the right to include additional Registrable
Securities in proportion (as nearly as practicable) to the total amount of
Registrable Securities held by each such Holder.

                      (c)    Notwithstanding any other provision of this Section
5, if the Underwriter determines that marketing factors require a limitation on
the number of shares to be underwritten, the Underwriter may limit the number of
Registrable Securities to be included in the registration and underwriting;
provided, however, that the number of shares of Registrable Securities offered
by the Holders and other holders that may be included in the registration and
underwriting shall be allocated among the Holders and other holders in
proportion, as nearly as practicable, to the respective aggregate amounts of
Registrable Securities and other securities entitled to registration held by
such Holders and other holders at the time of filing the registration statement.
If the Underwriter has not so limited the number of Registrable Securities to be
underwritten, the Company may include securities for its own account or the
account of others in such registration if the Underwriter so agrees and if the
number of Registrable Securities which would otherwise have been included in
such registration and underwriting will not thereby be limited or the price
applicable to such included Registrable Securities will not thereby be reduced.



                                       -9-
<PAGE>   10



               5.3    Subordination of Certain Rights. To the extent that the
Exchangeable Share Holders shall be able to utilize the closing date of the
Amalgamation as the original purchase date with respect to the Ordinary Shares
that such Exchangeable Share Holders ultimately receive in respect of such
Exchangeable Shares, for purposes of the holding period required under Rule
144(d) of the Securities Act (other than an inability to use such closing date
as the original purchase date for the purposes of Rule 144(d) due to an action
taken by the holder thereof, such as a pledge of shares, which tolls the holding
period under Rule 144(d)) so that such Exchangeable Shares Holders shall be able
to sell their Registrable Securities without registration under the Securities
Act, then the right of the Exchangeable Share Holders to include their
Registrable Securities in any registration as to which they exercise
registration rights shall be subordinate to the other holders of registration
rights and, in this regard, in the event that the underwriters of an offering
determine that marketing restrictions require a limitation in the total number
of shares to be included in the offering on behalf of holders of registration
rights, then all other holders of registration rights shall be entitled to
include the full number of shares in such registration and offering desired by
them before inclusion of shares in such registration and offering on the part of
the Exchangeable Share Holders. This Section 5.3 shall also apply to any
registration effectuated under the terms of Article 6 of this Agreement.

               5.4    Delay of Registration. If the Company shall furnish to the
Initiating Holders or the Exchangeable Share Initiating Holders, as the case may
be, a certificate signed by the President of the Company stating that, in the
good faith judgment of the Board of Directors of the Company, it would be not in
the best interests of the Company and its stockholders for such registration
statement to be filed on or before the date filing would be required and it is
therefore appropriate to defer the filing of such registration statement, then
the Company may direct that such request for registration be delayed for a
period not in excess of one hundred and eighty (180) days, such right to delay a
request to be exercised by the Company no more than once in any twelve month
period.

        6.     COMPANY REGISTRATION.

               6.1    Notice of Registration. If at any time or from time to
time the Company shall determine to register any of its equity securities,
either for its own account or the account of a security holder or holders, other
than (a) a registration relating solely to employee benefit plans, or (b) a
registration relating solely to a Rule 145 transaction, the Company shall:

                             (i)    promptly give to each Holder written notice
thereof; and

                             (ii)   include in such registration (and any
related qualification under blue sky laws or other compliance), and in any
underwriting involved therein, all the Registrable Securities specified in a
written request or requests, made within fifteen (15) days after receipt of such
written notice from the Company, by any Holder.

               6.2    Underwriting. If the registration of which the Company
gives notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 6.1(i). In such event the right of any Holder to
registration pursuant to this Section 6 shall be conditioned upon such Holder's
participation in such



                                      -10-
<PAGE>   11



underwriting and the inclusion of Registrable Securities in the underwriting to
the extent provided herein. All Holders proposing to distribute their securities
through such underwriting shall (together with the Company and the other holders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the Underwriter selected for such
Underwriting by the Company. Notwithstanding any other provision of this Section
6, if the Underwriter determines that marketing factors require a limitation of
the number of shares to be underwritten, the underwriter may limit, on a pro
rata basis, the Registrable Securities to be included in such registration;
provided, however, that in no public offering shall other holders of "piggyback"
registration rights participate in such offering unless the Holders (including
the Exchangeable Share Holders, unless such Exchangeable Share Holders shall be
entitled to use the closing date of the Amalgamation as the original purchase
date for their Ordinary Shares for Rule 144(d) purposes in the manner
contemplated by Section 5.3) have participated to the full extent requested. The
Company shall so advise all Holders and other holders distributing their
securities through such underwriting and the number of shares of Registrable
Securities and other securities that may be included in the registration and
underwriting shall be allocated among all Holders and other holders in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities and other securities entitled to registration held by such Holders
and other holders at the time of filing the registration statement. To
facilitate the allocation of shares in accordance with the above provisions, the
Company may round the number of shares allocated to any Holder or holder to the
nearest one hundred (100) shares. If any Holder or holder disapproves of the
terms of any such underwriting, he may elect to withdraw therefrom by written
notice to the Company and the managing underwriter.

               6.3    Right to Terminate Registration. The Company shall have
the right to terminate or withdraw any registration initiated by it under this
Section 6 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration.

        7.     REGISTRATION ON FORM F-3.

               (a)    If any Holder or Holders request that the Company file a
registration statement on Form F-3 (or any successor form to Form F-3) for a
public offering of shares of the Registrable Securities the reasonably
anticipated aggregate price to the public of which, net of underwriting
discounts and commissions, would exceed $1,000,000 and the Company is a
registrant entitled to use Form F-3 to register the Registrable Securities for
such an offering, the Company shall use its best efforts to cause such
Registrable Securities to be registered for the offering on such form and to
cause such Registrable Securities to be qualified in such jurisdictions as the
Holder or Holders may reasonably request; provided, however, that the Company
shall not be obligated to effect more than four (4) registrations under this
Section 7.

               (b)    Notwithstanding the foregoing, the Company shall not be
obligated to take any action pursuant to this Section 7: (i) more than once in
any twelve (12) month period; (ii) in any particular jurisdiction in which the
Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act; (iii) if the Company, within ten (10) days of the receipt of
the request of a Holder or Holders pursuant to this Section 7, gives notice of
its bona fide intention to effect the filing of a registration statement with
the



                                      -11-
<PAGE>   12
Commission within sixty (60) days of receipt of such request (other than with
respect to a registration statement relating to a Rule 145 transaction, an
offering solely to employees or any other registration which is not appropriate
for the registration of Registrable Securities) in which such Holders can
exercise their rights pursuant to Section 6 hereof; or (iv) during the period
starting with the date sixty (60) days prior to the Company's estimated date of
filing of, and ending on the date three (3) months immediately following, the
effective date of any registration statement pertaining to securities of the
Company (other than a registration of securities in a Rule 145 transaction or
with respect to an employee benefit plan), provided that the Company is actively
employing in good faith all reasonable efforts to cause such registration
statement to become effective.

               (c)    Registrations effected pursuant to this Section 7 shall
not be counted as demands for registration or registrations effected pursuant to
Section 5 or Section 6, respectively.

        8.     LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and after the
date of this Agreement, the Company shall not, without the consent of Holders of
in excess of 50% of the Registrable Securities, enter into any agreement
granting any holder or prospective holder of any securities of the Company
registration rights with respect to such securities, unless (i) such new
registration rights, including standoff obligations, are on a basis no more
favorable to the holders thereof than those rights of the Holders hereunder
(other than Exchangeable Share Holders, to the extent of subordination under
Section 5.3); or (ii) such new registration rights, including standoff
obligations, are subordinate to the registration rights granted Holders
hereunder.

        9.     EXPENSES OF REGISTRATION. All Registration Expenses incurred in
connection with all registrations pursuant to Section 5, Section 6 and Section 7
shall be borne by the Company. All Selling Expenses relating to securities
registered on behalf of the Holders shall be borne by the Holders of such
securities pro rata on the basis of the number of shares so registered.
Notwithstanding anything in this Section 9 to the contrary, if the Company
and/or others include securities for their own account pursuant to Section 5.2,
then the Company and such others shall bear their pro rata share of the
Registration Expenses and Selling Expenses.

        10.    REGISTRATION PROCEDURES. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Agreement,
the Company shall keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof. At its expense the Company shall:

               (a)    Prepare and file with the Commission a registration
statement, and all requisite supplements and amendments thereto, with respect to
such securities and use its best efforts to cause such registration statement,
as amended, to become and remain effective for at least one hundred twenty (120)
days or until the distribution described in the Registration Statement has been
completed;

               (b)    Furnish to the Holders participating in such registration
and to the underwriters of the securities being registered such reasonable

any such states or jurisdictions;

               (d)    In the event of any underwritten public offering, enter

customary form, with the underwriter of such offering;

               (e)    Notify each Holder of Registrable Securities covered by

as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to

               (f)    Furnish, at the request of any Holder requesting

        11.    INDEMNIFICATION.

               (a)    The Company will indemnify each Holder, each of its
officers and directors and partners, and each person controlling such Holder
within the meaning of Section 15 of the Securities Act, with respect to which
registration, qualification or compliance has been effected pursuant to this
Agreement, and each underwriter, if any, and each person who controls any
underwriter within the meaning of Section 15 of the Securities Act, or the
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), against all
expenses, claims, losses, damages or liabilities (joint or several) (or actions
in respect thereof), to which they become subject under the Securities Act or
the Exchange Act, including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any



                                      -13-
<PAGE>   14



registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereto, incident to any such registration,
qualification or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances in which they were
made, not misleading, or any violation by the Company of the Securities Act or
the Exchange Act or any rule or regulation promulgated thereunder applicable to
the Company in connection with any such registration, qualification or
compliance, and the Company will pay to each such Holder, each of its officers
and directors, and each person controlling such Holder, each such underwriter
and each person who controls any such underwriter, any legal and any other
expenses reasonably incurred as such expenses are incurred in connection with
investigating, preparing or defending any such claim, loss, damage, liability or
action, provided that the Company will not be liable in any such case to the
extent that any such claim, loss, damage, liability or expense arises out of or
is based on any untrue statement or omission or alleged untrue statement or
omission, made in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder,
controlling person or underwriter and stated to be specifically for use therein;
provided, however, that the indemnity agreement contained in this Section 11(a)
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Company, which consent shall not be unreasonably withheld.

               (b)    Each Holder will, if Registrable Securities held by such
Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors and officers, each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
the Company or such underwriter within the meaning of Section 15 of the
Securities Act or the Exchange Act, and each other such Holder, each of its
officers and directors and each person controlling such Holder within the
meaning of Section 15 of the Securities Act or the Exchange Act, against all
claims, losses, damages and liabilities (or actions in respect thereof) to which
any of the foregoing persons may become subject under the Securities Act or the
Exchange Act, arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement,
prospectus, offering circular or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Company, such Holders, such directors, officers, persons, underwriters or
control persons for any legal or any other expenses reasonably incurred as such
expenses are incurred in connection with investigating or defending any such
claim, loss, damage, liability or action, in each case to the extent, but only
to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
prospectus, offering circular or other document in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Holder and stated to be specifically for use therein;
provided, however, that the indemnity agreement contained in this Section 11(b)
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Holder, which consent shall not be unreasonably withheld. Notwithstanding the
foregoing, the liability of each Holder under this Section 11(b) shall be
limited to an amount equal to the aggregate proceeds received by such Holder
from the sale of Registrable Securities hereunder, unless such liability arises
out of or is based on willful conduct by such Holder.



                                      -14-
<PAGE>   15



               (c)    Each party entitled to indemnification under this Section
11 (the "INDEMNIFIED PARTY") shall give notice to the party required to provide
indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations under this Agreement unless the failure to give such notice is
materially prejudicial to an Indemnifying Party's ability to defend such action
and provided further, that the Indemnifying Party shall not assume the defense
for matters as to which there is a conflict of interest or separate and
different defenses. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

        12.    INFORMATION BY HOLDER. The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders, the Registrable Securities held by
them and the distribution proposed by such Holder or Holders as the Company may
reasonably request in writing and as shall be required in connection with any
registration, qualification or compliance referred to in this Agreement.

        13.    RULE 144 REPORTING. With a view to making available the benefits
of certain rules and regulations of the Commission which may at any time permit
the sale of the Restricted Securities to the public without registration, after
such time as a public market exists for the Ordinary Shares of the Company, the
Company agrees to use its best efforts to:

               (a)    Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the effective date that the Company becomes subject to the reporting
requirements of the Securities Act or the Exchange Act.

               (b)    Use its best efforts to file with the Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements);

               (c)    Take such action, including the voluntary registration of
its Ordinary Shares under Section 12 of the Exchange Act, as is necessary to
enable the Holders to utilize Form F-3 for the sale of their Registrable
Securities, such registration under Section 12 to be taken as soon as
practicable after the six-month period following the date on which the first
registration statement filed by the Company for the offering of its securities
to the general public is declared effective.

               (d)    So long as a Purchaser owns any Restricted Securities to
furnish to the Purchaser forthwith upon request a written statement by the
Company as to its compliance with the reporting



                                      -15-
<PAGE>   16



requirements of said Rule 144 (at any time after ninety (90) days after the
effective date of the first registration statement filed by the Company for an
offering of its securities to the general public), and of the Securities Act and
the Exchange Act (at any time after it has become subject to such reporting
requirements), a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents of the Company and other
information in the possession of or reasonably obtainable by the Company as a
Purchaser may reasonably request in availing itself of any rule or regulation of
the Commission allowing a Purchaser to sell any such securities without
registration.

        14.    TRANSFER OF REGISTRATION RIGHTS. The rights to cause the Company
to register securities granted to a Holder under Sections 5, 6 and 7 may be
assigned (i) to partners and constituent members, former partners and former
constituent members and Affiliates of that Holder, and (ii) to other persons
provided that (a) such transfer may otherwise be effected in accordance with
applicable securities laws, (b) such assignee or transferee acquires at least
800,000 shares of Registrable Securities (as may be appropriately adjusted upon
any stock split, stock dividend, recapitalization, merger, consolidation or
similar event) and (c) such assignee or transferee agrees to be bound by the
terms of this Agreement and assumes all of the obligations of the transferring
Holder hereunder.

        15.    STANDOFF AGREEMENT. Each Holder hereby agrees that, during the
period of duration specified by the Company and an underwriter of Ordinary
Shares or other securities of the Company, following the effective date of a
registration statement of the Company filed under the Securities Act, it shall
not, to the extent requested by the Company and such underwriter, directly or
indirectly sell, offer to sell, contract to sell (including, without limitation,
any short sale), grant any option to purchase or otherwise transfer or dispose
of (other than to donees who agree to be similarly bound) any securities of the
Company held by it at any time during such period except Ordinary Shares
included in such registration; provided, however, that:

               (a)    all officers and directors of the Company enter into
similar agreements; and

               (b)    the Company shall use all reasonable efforts to obtain a
similar covenant from all holders of at least 1% of the Company's outstanding
securities;

               (c)    such market stand-off time period shall not exceed one
hundred eighty (180) days except as may be agreed by holders of a majority of
the then outstanding Registrable Securities.

        Each Holder agrees to provide to the other underwriters of any public
offering such further agreement as such underwriter may require in connection
with this market stand-off agreement. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of each Holder (and the shares or securities of every
other person subject to the foregoing restriction) until the end of such period.



                                      -16-
<PAGE>   17



        16.    TERMINATION OF REGISTRATION RIGHTS. The rights granted and
obligations imposed pursuant to Sections 1 through 15 of this Agreement shall
terminate as to any Holder at such time as such Holder beneficially owns less
than 1% of the Company's outstanding capital stock.

        17.    RIGHT OF FIRST REFUSAL FOR ISSUANCE OF NEW SECURITIES. The
Company hereby grants to each Major Holder the right of first refusal to
purchase a Pro Rata Share (as defined below) of any New Securities (as defined
in subsection 17(a)) which the Company may, from time to time, propose to sell
and issue. A "PRO RATA SHARE," for purposes of this right of first refusal,
shall be a fraction, the numerator of which is the sum of the number of shares
of Ordinary Shares then held by such Major Holder or issuable to such Major
Holder upon conversion of the Preferred, Exchangeable Shares or Warrants held by
such Major Holder, and the denominator of which is the sum of the total number
of Ordinary Shares then outstanding and the number of Ordinary Shares issuable
upon conversion or exercise of all outstanding capital stock, options or
warrants convertible into or exercisable for Ordinary Shares (without giving
effect to up to 3,746,308 options available for grant pursuant to the Company's
option plan).

               (a)    Except as set forth below, "NEW SECURITIES" shall mean any
shares of capital stock of the Company, including Ordinary Shares and Preferred,
whether now authorized or not. Not withstanding the foregoing, "NEW SECURITIES"
does not include:

                      (i)    any dividend payable in Ordinary Shares or any
shares issued upon a subdivision or combination of Ordinary Shares;

                      (ii)   Ordinary Shares issued upon conversion of
outstanding equity securities of the Company, including the Preferred and the
Exchangeable Shares;

                      (iii)  Ordinary Shares, or options exercisable therefor,
including options outstanding on the date of this Agreement, issued pursuant to
any existing stock or option plan, as may be amended, or pursuant to a
compensatory stock or option plan which is hereafter approved by the Board of
Directors;

                      (iv)   securities issued in consideration for an
acquisition (whether by merger or otherwise) by the Company;

                      (v)    New Securities sold by the Company in an
underwritten or other public offering pursuant to an effective registration
statement or a prospectus under U.S. or Israeli securities laws;

                      (vi)   New Securities issued in connection with equipment
leases or secured debt financings;

                      (vii)  securities issued on exercise of options or
conversion of convertible securities where the original issuance of the option
or convertible security was subject to this right of first refusal; or



                                      -17-
<PAGE>   18



                      (viii) securities issued in a transaction where holders of
greater than (a) 66 2/3% of the Series D Preferred, (b) 66 2/3% of the Series
C-1 Convertible Preferred, (c) 50% of the Series B Preferred and (d) 50% of the
Series A Preferred, each agree that this right of first refusal will not apply.

               (b)    In the event that the Company proposes to undertake an
issuance of New Securities, it shall give each Major Holder written notice of
its intention, describing the type of New Securities, and the price and terms
upon which the Company proposes to issue the same. Each such Major Holder shall
have twenty (20) days from the date of receipt of any such notice to agree to
purchase up to its respective Pro Rata Share of such New Securities for the
price and upon the terms specified in the notice by giving written notice to the
Company and stating therein the quantity of New Securities to be purchased.

               (c)    In the event that such Major Holder fails to exercise the
right of first refusal within said fifteen (15) day period, the Company shall
have sixty (60) days thereafter to sell or enter into an agreement (pursuant to
which the sale of New Securities covered thereby shall be closed, if at all,
within thirty (30) days from the date of said agreement) to sell the New
Securities not elected to be purchased by such Major Holder at the price and
upon terms no more favorable to the purchasers of such securities than specified
in the Company's notice. In the event that the Company has not sold the New
Securities or entered into an agreement to sell the New Securities within said
sixty (60) day period (or sold and issued New Securities in accordance with the
foregoing within thirty (30) days from the date of said agreement), the Company
shall not thereafter issue or sell any New Securities without first offering
such securities in the manner provided above.

               (d)    The right of first refusal hereunder is not assignable, in
whole or in part, except (i) by a Major Holder that is a partnership to any of
its partners, (ii) by a Major Holder that is any venture capital group or fund
to an Affiliated entity or person, and (iii) by a Major Holder that is a
corporation to any of its shareholders, provided in any such case that the
transferee beneficially owns following such transfer a sufficient number of
shares of Registrable Securities to constitute a Major Holder.

               (e)    The right of first refusal granted under this Agreement
shall expire immediately prior to the closing of a Qualified IPO.

        18.    AFFIRMATIVE COVENANTS. The Company and each Purchaser hereby
covenant and agree as follows:

               18.1   Financial Information.

available;

                      (c)    Copies of all filings made with the Commission; and

                      (d)    any other financial or other information available
to the Company which such Major Holder shall reasonably request for purposes
properly related to such Major Holder's corporate status as a shareholder of the
Company.

               18.2   Confidential Information.

                      (a)    Each Major Holder agrees that any information
obtained by such Major Holder pursuant to Section 18.1 which is, or would
reasonably be perceived to be, proprietary to the Company or otherwise
confidential will not be disclosed without the prior written consent of the
Company. Notwithstanding the foregoing, each Major Holder may disclose such
information, on a need to know basis, to its employees, accountants or
attorneys, or to the employees, accountants or attorneys of its general partner
or investment manager (so long as each such person to whom confidential
information is disclosed agrees to keep such information confidential), in
compliance with a court order or when otherwise necessary to enforce any of the
Major Holder's rights hereunder. Such information may also be disclosed to a
Major Holder's constituent partners, members or shareholders (so long as each
such person to whom confidential information is disclosed agrees to keep such
information confidential). Each Major Holder further acknowledges and
understands that any information will not be utilized by such Major Holder in
connection with purchases and/or sales of the Company's securities except in
compliance with applicable state and federal antifraud statutes.

each of its subsidiaries duly to pay and discharge, all taxes, assessments and

subsidiaries shall have set aside on their books adequate reserves with respect
thereto.

               18.6   Insurance. The Company will apply for and continue in

<PAGE>   21

other corporations engaged in similar lines of business and with good and
responsible insurance companies.

mutilation upon surrender and cancellation of such shares, the Company, at the
Company's expense, will make and deliver a new certificate in lieu of the lost,
stolen, destroyed or mutilated certificate carrying the same rights and
obligations as the original certificate. The Company will also pay the cost of
all deliveries of certificates for such shares to such Purchaser (including the
cost of insurance against loss or theft in an amount satisfactory to the
holders) upon any exchange thereof.

                      "Hazardous Substances" shall mean any and all hazardous
               wastes that in any physical state might represent danger to the
               environmental balance because of their corrosive, toxic,
               venomous, reactive, explosive, flammable, biological or
               irritating conditions, such as: (a) any petroleum or petroleum
               products, flammable explosives, radioactive materials, asbestos
               in any form that is ore could become friable, urea, formaldehyde,

               Environmental Law or by any federal, state or municipal authority
               (whether in the United States, Israel or elsewhere).

case may be, originally purchased by them (and Ordinary Shares issued upon
conversion thereof) and (b) immediately prior to the closing of a Qualified IPO,

of conflict



                                      -22-

of interest may arise with respect to any Observer, all duties and obligations
that a member of the Board of Directors may have by virtue of the law, shall
apply to such Observer.

        20.    MISCELLANEOUS.

               20.1   Aggregation of Shares. For purposes of any provision of
this Agreement requiring a person or entity to hold a minimum number of shares
of Preferred or Exchangeable Shares (or Ordinary Shares issued upon conversion
thereof) or Registrable Securities in order to gain the benefit of such
provision, all shares beneficially owned by Affiliated entities or persons
(including partners and constituent members and former partners and former
constituent members) shall be aggregated together for the purposes of
determining such Holder's status or rights under such provision. For purposes of
this Section 20.1, Bayview shall be deemed an affiliate of Evergreen.

               20.2   Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Israel with respect to
matters of corporate law and the State of California with respect to all other
matters; provided, however, that (notwithstanding the foregoing) Section 18 of
this Agreement shall be governed and construed in accordance with the laws of
the State of California, and the Company hereby consents to the jurisdiction of
of any state or federal court in Santa Clara County, California arising out of
or in connection with Section 18 hereof. Each of the Purchasers and the Company
hereby submits to the nonexclusive jurisdiction of the courts in Tel Aviv,
Israel or the United States District Court for the Northern District of
California or any California state court sitting in Santa Clara County,
California, as the case may be, for purposes of all legal proceedings arising
out of or relating to this Agreement and the transactions contemplated hereby.
Each of the Purchasers and the Company irrevocably waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying
of the venue of any such proceeding brought in such a court and any claim that
any such proceeding brought in such a court has been brought in an inconvenient
forum.

               20.3   Survival. The representations, warranties, covenants and
agreements made herein shall survive any investigation made by any Purchaser of
the Series D Preferred and the closing of the transactions contemplated hereby.

               20.4   Successors and Assigns. Except as otherwise provided
herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, assigns, heirs, executors and administrators of the
parties hereto. Nothing in this Agreement, express or implied, is intended to
confer upon any party other than the parties hereto or their respective
successors and assigns any rights, remedies, obligations, or liabilities under
or by reason of this Agreement, except as expressly provided in this Agreement.

               20.5   (a)    Entire Agreement; Amendment. This Agreement and the
                      other documents delivered pursuant hereto constitute the
                      full and entire understanding and agreement between the
                      parties with regard to the subjects hereof and thereof,
                      and no party shall be liable or bound to any other party
                      in any manner by any warranties, representations or
                      covenants except as specifically set forth herein or
                      therein. In this regard, the parties to each of the Third
                      Rights Agreement and the Side Letters



                                      -23-
<PAGE>   24



agree that the Third Rights Agreement and the Side Letters are hereby terminated
and shall have no further force and effect, except only that, as between the
Company and GE, the GE Side Letter shall continue to remain in full force and
effect and as between the Company and all of the Series D Holders, the
representations and warranties contained in the side letter dated May 6, 1998
between the Company and the Series D Holders shall survive as set forth in
paragraph 3 thereof. Except as expressly provided herein, neither this Agreement
nor any term hereof may be amended, waived, discharged or terminated other than
by a written instrument signed by the party against whom enforcement of any such
amendment, waiver, discharge or termination is sought; provided, however, that
any provision of this Agreement may be amended, waived or modified with the
written consent of (i) the Company, (ii) the holders of at least a majority of
the Series B Preferred (and Ordinary Shares issued upon conversion thereof) then
outstanding, (iii) the holders of at least 66 2/3% of the Series C-1 Convertible
Preferred (and Ordinary Shares issued upon conversion thereof) then outstanding,
(iv) the holders of at least 66 2/3% of the Series D Convertible Preferred (and
Ordinary Shares issued upon conversion thereof) then outstanding, and (v) the
holders of at least a majority of the Exchangeable Shares (and Ordinary Shares
issued upon conversion thereof) then outstanding and having rights pursuant to
this Agreement.

                      (b)    Additional Parties. The Company and the
Shareholders whose signatures appear on the signature page hereto agree that
should the Company sell additional shares of Series D Preferred to Additional
Purchasers (as defined in the Purchase Agreement), such Additional Purchasers
shall, after executing copies of this Agreement as an additional Purchaser
hereunder, become Shareholders hereunder and shall have all rights of
Shareholders hereunder.

               20.6   Notices. All notices and other communications required or
permitted hereunder shall be in writing, shall be effective when given, and
shall in any event be deemed to be given upon receipt or, if earlier, (a) five
(5) days after deposit with the U.S. Postal Service or other applicable postal
service, if delivered by first class mail, postage prepaid if addressed to a
party in the same country or twenty (20) days after deposit with the U.S. Postal
Service or other applicable postal service, if delivered by first class mail,
postage prepaid if addressed to a party in a different country, (b) upon
delivery, if delivered by hand, (c) two (2) business day after the business day
of deposit with Federal Express or similar overnight courier, freight prepaid or
(d) one (1) business day after the business day of facsimile transmission, if
delivered by facsimile transmission with copy by first class mail, postage
prepaid, and shall be addressed (i) if to a Purchaser, at such Purchaser's
address as set forth in the Purchase Agreement other than for the Exchangeable
Share Holders whose address shall be as set forth in the records of the Company,
and (ii) if to the Company, at the address of its principal corporate offices
(attention: Secretary), or at such other address as a party may designate by ten
days' advance written notice to the other party pursuant to the provisions
above.

               20.7   Delays or Omissions. Except as expressly provided herein,
no delay or omission to exercise any right, power or remedy accruing to any
Holder of any Registrable Securities, upon any breach or default of the Company
under this Agreement, shall impair any such right, power or remedy of such
Holder nor shall it be construed to be a waiver of any such breach or default,
or an acquiescence therein, or of or in any similar breach or default thereafter
occurring; nor shall any waiver of any single breach or default be deemed a
waiver of any other breach or default theretofore or thereafter occurring. Any
waiver, permit, consent or approval of any kind or character on the part of any
Holder of any breach



                                      -24-
<PAGE>   25



or default under this Agreement, or any waiver on the part of any Holder of any
provisions or conditions of this agreement, must be in writing and shall be
effective only to the extent specifically set forth in such writing. All
remedies, either under this Agreement or by law or otherwise afforded to any
Holder, shall be cumulative and not alternative.

               20.8   Enforcement of Covenants. The Company hereby acknowledges
that remedies at law may be inadequate to protect the Purchasers against any
actual or threatened breach by the Company or any of its subsidiaries of the
covenants contained in Section 18 hereof and agree that the Purchasers shall be
entitled to seek specific performance of such covenants and injunctive or other
equitable relief as a remedy for any such breach; the Company further agrees to
waive any requirement for the securing or posting of any bond in connection with
such remedy. Such remedy shall not be deemed to be the exclusive remedy for the
breach of such covenants, but shall be in addition to all other remedies
available to the Purchasers at law or equity.

               20.9   Counterparts. This Agreement may be executed in any number
of counterparts, each of which may be executed by less than all of the
Purchasers, each of which shall be enforceable against the parties actually
executing such counterparts, and all of which together shall constitute one
instrument.

               20.10  Severability. In the event that any provision of this
Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force and
effect without said provision; provided that no such severability shall be
effective if it materially changes the economic benefit of this Agreement to any
party.

               20.11  Titles and Subtitles. The titles and subtitles used in
this Agreement are used for convenience only and are not considered in
construing or interpreting this Agreement.

                        AGREEMENT AND PLAN OF ACQUISITION


        This AGREEMENT AND PLAN OF ACQUISITION (the "Agreement") is made and
entered into as of July 1, 1997 by and among (i) BackWeb Technologies Ltd., a
company organized under the laws of Israel (the "BackWeb Parent"), (ii) BackWeb
Canada, Inc., a corporation incorporated under the laws of Ontario ("BackWeb
Canada"), (iii) Lanacom Inc., a corporation organized under the laws of Ontario,
("Lanacom") and (iv) Anthony Davis, the founder, President and principal
shareholder of Lanacom (the "Founder").


                                    RECITALS

        A.     The Boards of Directors of each of BackWeb Parent, BackWeb Canada
and Lanacom believe it is in the best interests of each company and their
respective shareholders that BackWeb Parent acquire Lanacom through the
amalgamation of BackWeb Canada and Lanacom (the "Amalgamation"; the corporation
continuing from such Amalgamation shall be referred to herein as the "Surviving
Corporation") and, in furtherance thereof, have approved the Amalgamation.

        B.     Pursuant to the Amalgamation, among other things, all of the
issued and outstanding common shares of Lanacom ("Lanacom Common Shares") shall
be exchanged for Class A Shares of the Surviving Corporation ("Class A Shares"),
which Class A Shares will immediately thereafter be changed into exchangeable
non-voting shares of the Surviving Corporation ("Exchangeable Shares") pursuant
to articles of amendment to be filed by the Surviving Corporation (the "Articles
of Reorganization") in accordance with the terms and subject to the conditions
set forth in this Agreement. Each Exchangeable Share shall thereafter be
exchangeable in accordance with its terms and the terms and conditions set forth
in a Voting and Exchange Trust Agreement (as defined in Section 1.17 herein) to
be entered into pursuant hereto, for one ordinary share of BackWeb Parent (a
"BackWeb Parent Ordinary Share"). To the extent that Lanacom has other
outstanding securities at the Closing Time (as defined below) representing
rights to acquire Lanacom Common Shares or other voting securities ("Other
Lanacom Securities"), all such rights under such Other Lanacom Securities shall
become rights to acquire Class A Shares and, subsequently, Exchangeable Shares,
in accordance with this Agreement.

        C.     A portion of the Exchangeable Shares otherwise deliverable by the
Surviving Corporation to the holders of Lanacom Shares in connection with the
transactions contemplated hereunder shall be placed in escrow, the release of
which shall be contingent upon certain events and conditions.

        D.     BackWeb Parent, BackWeb Canada, Lanacom and the Founder desire to
make certain representations and warranties and other agreements in connection
with the Amalgamation.



<PAGE>   7



        NOW, THEREFORE, in consideration of the covenants, promises,
representations and warranties set forth herein, and for other good and valuable
consideration, the parties to this Agreement hereby agree as follows:

                                    ARTICLE I

                             THE PLAN OF ACQUISITION

        1.1    The Amalgamation. At the Closing Time (as defined in Section 1.2
below) and subject to and upon the terms and conditions of this Agreement and
the applicable provisions of the Business Corporations Act (Ontario) (the "Act")
BackWeb Canada and Lanacom shall be amalgamated in order to create the Surviving
Corporation.

        1.2    Closing Time. Unless this Agreement is earlier terminated
pursuant to Section 9.1, the closing of the Amalgamation (the "Closing") will
take place as promptly as practicable, but no later than two (2) business days
following the later of (a) satisfaction or waiver of the conditions set forth in
Article VI, and (b) ten (10) business days following the date of this Agreement
at the offices of Wilson Sonsini Goodrich & Rosati, Professional Corporation,
650 Page Mill Road, Palo Alto, California, unless another place or time is
expressly agreed to in writing by BackWeb Parent and Lanacom. The date upon
which the Closing actually occurs is herein referred to as the "Closing Date."
On the Closing Date, the parties hereto shall cause the Amalgamation to be
consummated by (i) executing and delivering an agreement (the "Amalgamation
Agreement") substantially in the form attached hereto as Exhibit A, duly
completed in accordance with this Agreement, and (ii) filing Articles of
Amalgamation with the Director under the Act in the form attached as Exhibit B
hereto (the "Articles of Amalgamation"), in accordance with the relevant
provisions of the Act (the time that such Articles of Amalgamation become
effective under the Act being referred to herein as the "Closing Time").

        1.3    Effect of the Amalgamation. At the Closing Time, the effect of
the Amalgamation shall be as provided under Section 179 of the Act. Without
limiting the generality of the foregoing, and subject thereto, at the Closing
Time, the separate corporate existence of each of BackWeb Canada and Lanacom
shall cease, all the property, rights, privileges, powers and franchises of
BackWeb Canada and Lanacom shall vest in the Surviving Corporation, and all
debts, liabilities, obligations and duties of BackWeb Canada and Lanacom shall
become the debts, liabilities, obligations and duties of the Surviving
Corporation. The name of the Surviving Corporation shall be "BackWeb Canada
Inc."

        1.4    Directors and Officers. The directors of the Surviving
Corporation immediately after the Closing Time shall be the individuals
identified as directors of the Surviving Corporation in the Amalgamation
Agreement.

        1.5    Effect on Lanacom Common Shares. Subject to the terms and
conditions of this Agreement, as of the Closing Time, by virtue of the
Amalgamation and without any action on the part of BackWeb Canada, Lanacom or
the holder of any Lanacom Common Shares, and immediately



                                       -2-
<PAGE>   8



thereafter, upon the filing of the Articles of Reorganization by the Surviving
Corporation, in each case as more fully described below, the following shall
occur:

               (a)    Definitions.

                      (i)    Aggregate Common Number. The "Aggregate Common
Number" shall mean the aggregate number of Lanacom Common Shares and other
voting securities outstanding immediately prior to the Closing Time.

                      (ii)   Aggregate Option Number. The "Aggregate Option
Number" shall mean the aggregate number of Lanacom Common Shares and other
voting securities issuable upon conversion or exercise of all Other Lanacom
Securities outstanding immediately prior to the Closing Time, whether or not
such Other Lanacom Securities shall then be vested and exercisable.

                      (iii)  Fully Diluted Common Number. The "Fully Diluted
Common Number" shall mean, without duplication, the sum of (y) the Aggregate
Common Number and (z) the Aggregate Option Number.

                      (iv)   Aggregate Share Number or Amalgamation
Consideration. The "Aggregate Share Number" or "Amalgamation Consideration"
shall consist of an aggregate of _________ Class A Shares to be changed into
_________ Exchangeable Shares (subject to adjustment to reflect the effect of
any stock split, stock dividend, reorganization, recapitalization or the like
with respect to the BackWeb Parent Ordinary Shares and subject to adjustment
pursuant to Sections 1.6 and 5.10 hereof).

                      (v)    Exchange Ratio. The "Exchange Ratio" shall mean the
quotient obtained by dividing (y) the ______________________ by (z) the _____
_____________________.

                      (vi)   Escrow Amount. The "Escrow Amount" shall consist of
an aggregate of _________ Exchangeable Shares (being 30% of the Aggregate Share
Number) as adjusted pursuant to Section 7.2(d)(iv)).

                      (vii)  Proportionate Escrow Interest. The "Proportionate
Escrow Interest" applicable to each holder of record of Lanacom Common Shares
(each, a "Holder in Escrow") as of immediately prior to the Closing Time, shall
mean the quotient obtained by _____________________________.

               (b)    Exchange of Lanacom Common Shares for Class A Shares. Upon
the Amalgamation each Lanacom Common Share issued and outstanding immediately
prior to the Closing Time (other than any Dissenting Shares (as defined in and
to the extent provided in Section 1.8)) will automatically be exchanged for that
number of Class A Shares equal to the Exchange Ratio (as defined in Section
1.5(a) above).



                                       -3-
<PAGE>   9

               (c)    Change of Class A Shares into Exchangeable Shares.
Immediately following the amalgamation and the exchange of Lanacom Common Shares
for Class A Shares pursuant to paragraph (b) above, the Surviving Corporation
shall file the Articles of Reorganization and, pursuant thereto, each Class A
Share issued upon the Amalgamation shall immediately be changed without further
action on the part of any holder of Class A Shares, into one Exchangeable Share.

               (d)    Delivery of Exchangeable Shares; Escrow. Upon the issuance
of the Exchangeable Shares in accordance with paragraph (c) above, that number
of Exchangeable Shares equal to the Escrow Amount shall be placed in escrow in
accordance with Section 1.9 and Article VII hereof to be distributed in
accordance with Article VII hereof, and all other Exchangeable Shares shall be
distributed to the registered holders thereof (being the registered holders of
the Lanacom Common Shares exchanged for Class A Shares upon the Amalgamation
which were changed into such Exchangeable Shares upon the filing of the Articles
of Reorganization) and certificates representing such Exchangeable Shares shall
be delivered to such holders in accordance with section 1.10.

               (e)    Other Lanacom Securities. At the Closing Time, all Other
Lanacom Securities shall continue to have, and be subject to, the same terms and
conditions of such Other Lanacom Securities immediately prior to the Closing
Time, except that (A) each Other Lanacom Security shall be exercisable for that
whole number of Class A Shares equal to the product of the number of Lanacom
Common Shares that were issuable upon exercise of such Other Lanacom Security
immediately prior to the Closing Time multiplied by the Exchange Ratio (as
defined in Section 1.5 above), rounded up to the nearest whole number of Class A
Shares, (B) the per share exercise price for Class A Shares issuable upon
exercise of such Other Lanacom Security shall be equal to the quotient
determined by dividing the exercise price per Lanacom Common Share at which such
Other Lanacom Security was exercisable immediately prior to the Closing Time by
the Exchange Ratio, rounded down to the nearest whole cent. Immediately
following the Closing Time and upon the filing of the Articles of
Reorganization, the right to receive Class A Shares upon exercise of such Other
Lanacom Securities shall become a right to receive the same number of
Exchangeable Shares, and the Surviving Corporation will issue to each holder of
outstanding Other Lanacom Securities a document evidencing the foregoing changes
to such Other Lanacom Securities.

               (f)    Fractional Shares. No fraction of a Class A Share shall be
issued, but in lieu thereof, the number of Class A Shares issuable to any holder
of Lanacom Common Shares shall be rounded up to the nearest whole Class A Share,
after aggregating all fractional Class A Shares to be received by such holder.

        1.6    Adjustments in the Aggregate Share Number. The Aggregate Share
Number shall be subject to adjustment on the Closing Date as provided in this
Section 1.6.

               (a)    Preliminary Balance Sheet. On the date being five (5) days
prior to the Closing Date, Lanacom shall deliver a balance sheet of Lanacom, as
of June 30, 1997 (as adjusted to reflect (x) the exercise of outstanding Lanacom
Warrants for Lanacom Common Shares, or the expiration or cancellation of the
Lanacom Warrants and (y) the exchange of outstanding Lanacom indebtedness for
Lanacom Common Shares, in each case pursuant to the Pre-Closing Reorganization
(as defined in Section 2.2(a)(iii) hereof), at any time from June 30, 1997 to
Closing), prepared by Lanacom in consultation with Lanacom's auditors and
BackWeb Parent (the "Preliminary Balance Sheet"). The



                                       -4-
<PAGE>   10

Preliminary Balance Sheet shall be prepared in accordance with Canadian
generally accepted accounting principles ("Canadian GAAP") consistent with the
basis of accounting and procedures and methods employed by Lanacom in preparing
the Lanacom Financial Statements.

               (b)    Definition of Net Asset Value. "Net Asset Value" shall
mean the aggregate of all tangible assets of Lanacom, including cash, net
accounts receivable (less (without duplication) allowances for doubtful
accounts), any amounts receivable in respect of an anticipated tax credit or
return, net value of inventory (adjusted for all applicable write-downs and
write-offs) and prepaid expenses, less all liabilities of any kind, including,
but not limited to, accounts payable, royalties payable, warranty and other
reserves, accrued bonuses, accrued vacation, employee expense obligations,
deferred revenue and all other liabilities to the extent that such liabilities
shall be required to be reflected in accordance with Canadian GAAP.

               (c)    Adjustment on Closing Date. In the event that the Net
Asset Value as set forth on the Preliminary Balance Sheet (the "Preliminary Net
Asset Value") is more negative than US$(_______), then the Aggregate Share
Number shall be reduced (reflecting the parties' agreement that one-third of the
risk of such event shall be borne by the shareholders of Lanacom and two-thirds
of the risk shall be borne by BackWeb Parent) by a number of Class A Shares
equal to one-third of the quotient obtained by dividing (y) the sum of the
Preliminary Net Asset Value plus US$_______ by (z) the value of the BackWeb
Parent Ordinary Shares on the Closing Date, US$____ per share.

        1.7    Net Liabilities Adjustment after Closing Date. The Aggregate
Share Number shall be subject to adjustment after the Closing Date as provided
in this Section 1.7, but only to the extent of any differences between the
Preliminary Balance Sheet and the Final Balance Sheet so as not to duplicate any
adjustment in the Aggregate Share Number effected pursuant to Section 1.6.

               (a)    Final Closing Balance Sheet. As soon as practicable (but
in no event later than 60 days) after the Closing Date, the Surviving
Corporation will prepare and cause to be audited by Ernst & Young LLP,
independent auditors (or such other independent auditors as are selected by
BackWeb Parent), and the Surviving Corporation will deliver to BackWeb Parent
and the Agent (as defined in Article VII), a balance sheet of Lanacom, as of
June 30, 1997 (as adjusted to reflect (x) the exercise of outstanding Lanacom
Warrants for Lanacom Common Shares, or the expiration or cancellation of the
Lanacom Warrants and (y) the exchange of outstanding Lanacom indebtedness for
Lanacom Common Shares, in each case pursuant to the Pre-Closing Reorganization
(as defined in Section 2.2(a)(iii) hereof), at any time from June 30, 1997 to
Closing), (the "Final Balance Sheet"). The Final Balance Sheet shall be prepared
in accordance with Canadian GAAP consistent with the basis of accounting and
procedures and methods employed by Lanacom in preparing the Lanacom Financial
Statements. During the conduct of such audit, the Surviving Corporation shall
cooperate in all respects with the independent auditors for the purpose of
completing the Final Balance Sheet. In addition, the Surviving Corporation and
the independent auditors shall be available for periodic inquiry by BackWeb
Parent and the Agent, and the independent auditors will answer such questions as
BackWeb Parent or the Agent may have and provide such additional schedules and
materials as BackWeb Parent or the Agent may reasonably request in order to
permit a meaningful review of the Final Balance Sheet.

               (b)    Adjustment Pursuant to Final Balance Sheet. In the event
that the Net Asset Value as set forth on the Final Balance Sheet (the "Final Net
Asset Value") is more negative than



                                       -5-
<PAGE>   11

US$_________ and is more negative than the Preliminary Net Asset Value, then the
Aggregate Share Number shall be reduced (reflecting the parties' agreement that
one-third of the risk of such event shall be borne by the shareholders of
Lanacom and two-thirds of the risk shall be borne by BackWeb Parent) by a number
of Exchangeable Shares equal to one-third of the quotient obtained by dividing
(y) the difference between the lesser of (i) US$_________ and the Preliminary
Net Asset Value and (ii) the Final Net Asset Value by (z) the value of the
BackWeb Parent Ordinary Shares on the Closing Date, US$____ per share. BackWeb
Parent shall provide written notice of such deficiency to the Escrow Agent
pursuant to the provisions of Section 7.2(d). This reduction in the Aggregate
Share Number shall be effected by the delivery by the Escrow Agent to the
Surviving Corporation of such specified number of Exchangeable Shares remaining
in the Escrow Fund pursuant to the escrow claim procedures set forth in such
Section 7.2(d), for cancellation by the Surviving Corporation for no
consideration.

               (c)    Disputes. At any time within 30 days following the
delivery of the Final Balance Sheet to BackWeb Parent and the Agent (the "Review
Period"), BackWeb Parent or the Agent may dispute any amounts reflected or not
reflected on the Final Balance Sheet to the extent the net effect of all such
disputed amounts in the aggregate would affect the Net Asset Value, but only on
the basis that such amounts were not arrived at in accordance with Section 1.7;
each of BackWeb Parent and the Agent will notify the other in writing of each
such disputed item, and will specify the amount thereof in dispute, not later
than the expiration of the Review Period. If BackWeb and the Agent are able to
resolve all the disputed items, then the Final Balance Sheet agreed upon by
BackWeb and the Agent will be final, binding and conclusive on the parties
hereto. If BackWeb and the Agent are unable to resolve any disputed item and are
therefore unable to agree as to the Final Balance Sheet and the resultant Final
Net Asset Value within 20 days following the expiration of the Review Period,
then within 10 days thereafter either BackWeb Parent or the Agent may elect that
the items remaining in dispute be submitted for resolution to a nationally
recognized accounting firm (the member of which who will be primarily
responsible for resolving such disputes will have had substantial auditing
experience and substantial experience in arbitration or other dispute resolution
proceedings concerning accounting issues) selected by mutual agreement of
BackWeb Parent and the Agent (or failing such agreement between BackWeb Parent
and the Agent, as selected by mutual agreement between BackWeb Parent's
independent accountants and Lanacom's independent accountants (prior to the
Amalgamation), or failing such agreement between BackWeb Parent's and Lanacom's
respective independent accounts, appointed by the American Arbitration
Association) (the "Accountants"). The Accountants will, within 30 days after
submission, determine, based solely on presentations by BackWeb Parent and the
Agent (and their representatives) and not by independent review, and render a
written report to the parties upon, such remaining disputed items and the
resultant calculation of the Final Balance Sheet and the Final Net Asset Value
in accordance with the provisions hereof, and such report and the resultant
Final Balance Sheet will be final, binding and conclusive on the parties hereto.
In resolving any disputed item, the Accountants may not assign a value to such
item greater than the greatest value for such item claimed by either party or
less than the smallest value for such item claimed by either party. The fees and
disbursements of the Accountants (and of the American Arbitration Association,
if any) (a) will be paid by the Surviving Corporation, and BackWeb Parent shall
be deemed to have incurred a Loss under Article VII equal to the amount thereof,
if the Final Net Asset Value finally determined pursuant to this Section 1.7
shall be less than US$10,000 greater than the Final Net Asset Value reflected on
the Final Balance Sheet originally submitted pursuant to Section 1.7, or (b)
will be borne by BackWeb Parent with



                                       -6-
<PAGE>   12

no deemed Loss under Article VII hereof, if the Final Net Asset Value finally
determined pursuant to this Section 1.7 is more than US$______ greater than the
Net Asset Value amount reflected on the Final Balance Sheet originally submitted
pursuant to Section 1.7 hereof. BackWeb Parent, the Surviving Corporation and
the Agent hereby agree to cooperate and work in good faith and as expeditiously
as reasonably possible to resolve any and all Final Balance Sheet disputes.

        1.8    Dissenting Shares.

               (a)    Notwithstanding any provision of this Agreement to the
contrary, any Lanacom Common Shares held by a holder who has exercised dissent
rights for such shares in accordance with Section 185 of the Act and who, as of
the Closing Time, has not effectively withdrawn or lost such dissent rights
("Dissenting Shares"), shall not be exchanged for Class A Shares pursuant to
Section 1.5, but the holder thereof shall only be entitled to such rights as are
granted by Section 185 of the Act.

               (b)    Notwithstanding the provisions of subsection (a), if any
holder of Dissenting Shares shall effectively withdraw or lose (through failure
to perfect or otherwise) his or her dissent rights, then, as of the later of
Closing Time and the occurrence of such event, such holder's shares shall
automatically be converted into and represent only the right to receive Class A
Shares as provided in Section 1.5(b) (and, upon the change thereof pursuant to
the Articles of Reorganization under Section 1.5(c), Exchangeable Shares),
without interest thereon, upon surrender of the certificate representing such
shares, subject to the conditions set forth below and throughout this Agreement,
including without limitation the escrow provisions set forth in Section 1.9 and
Article VII hereof.

               (c)    Lanacom shall give BackWeb Parent (i) prompt notice of any
exercise of dissent rights received by Lanacom pursuant to the applicable
provisions of Section 185 of the Act and (ii) the opportunity to participate in
all negotiations and proceedings with respect thereto. Lanacom shall not, except
with the prior written consent of BackWeb Parent, voluntarily make any payment
with respect to any such demands or offer to settle or settle any such exercise
of dissent rights. To the extent that BackWeb Parent or Lanacom makes any
payment or payments in respect of any Dissenting Shares, BackWeb Parent shall be
deemed to have incurred a Loss under Article VII hereof equal to (x) the
aggregate amount by which such payment or payments exceed the aggregate
Amalgamation Consideration that otherwise would have been payable in respect of
such Dissenting Shares plus (y) one-half of the aggregate fees and expenses
(including reasonable attorneys' fees and expenses) incurred by BackWeb Parent
or the Surviving Corporation in connection with calculating, settling or
litigating the amount of, or making, any such payment.

        1.9    Escrow. Promptly after the Closing Time and upon the issuance of
the Exchangeable Shares pursuant to Section 1.5(c), the Surviving Corporation
shall deposit Exchangeable Shares constituting the Escrow Amount into an escrow
account pursuant to Article VII below. The portion of the Escrow Amount
contributed on behalf of each Holder in Escrow shall be nearly as may be
practical in proportion to the product of (x) the aggregate number of
Exchangeable Shares constituting the Escrow Amount times (y) such holder's
Proportionate Escrow Interest (as defined in Section 1.5).

        1.10   Surrender of Certificates.

               (a)    Exchange Agent. The Surviving Corporation or such other
party mutually agreed by the parties shall act as exchange agent in the
Amalgamation (the "Exchange Agent").

               (b)    Surviving Corporation to Provide Exchangeable Shares.
Promptly after the Closing Time, the Surviving Corporation shall make available
to the Exchange Agent, for exchange in accordance with this Article I, the
aggregate number of Exchangeable Shares outstanding following the change
(pursuant to the Articles of Reorganization) of the Class A Shares issuable
pursuant to Section 1.5 in exchange for outstanding Lanacom Common Shares;
provided that (i) no Exchangeable Shares shall be deposited in respect of
Lanacom Common Shares as to which dissent rights have been exercised and not
withdrawn under Section 1.8 and (ii) the Surviving Corporation shall deposit
into escrow on behalf of the holders of Lanacom Common Shares a number of
Exchangeable Shares equal to the Escrow Amount.

               (c)    Exchange Procedures. As soon as reasonably practicable
after the Closing Time, the Surviving Corporation shall cause to be delivered,
to each holder of record of a certificate or certificates (the "Certificates")
which immediately prior to the Closing Time represented outstanding Lanacom
Common Shares whose shares were exchanged for Class A Shares upon the
Amalgamation and changed into Exchangeable Shares pursuant to Section 1.5, (i),
a letter of transmittal (which shall specify that delivery shall be effected,
and risk of loss and title to the Certificates shall pass, only upon delivery of
the Certificates to the Exchange Agent and shall be in such form and have such
other provisions as BackWeb Parent may reasonably specify) and (ii) instructions
for use in effecting the surrender of the Certificates in exchange for
certificates representing Exchangeable Shares. No certificates shall be issued
by the Surviving Corporation in respect of any Class A Shares. Upon surrender of
a Certificate for cancellation to the Exchange Agent or to such agent or agents
as may be appointed by BackWeb Parent, together with such letter of transmittal,
duly completed and validly executed in accordance with the instructions thereto,
the holder of such Certificate shall be entitled to receive in exchange therefor
a certificate representing the number of whole Exchangeable Shares issued to
such holder pursuant to Section 1.5 (subject to the escrow provisions of Section
1.9 and Article VII) and the Certificate so surrendered shall forthwith be
canceled. Until so surrendered, each outstanding Certificate that, prior to the
Closing Time, represented Lanacom Common Shares, will be deemed from and after
the Closing Time, to evidence only the right to receive Exchangeable Shares in
respect of each such share (subject to the escrow provisions of Section 1.9 and
Article VII).

               (d)    Distributions With Respect to Unexchanged Shares. No
dividends or other distributions with respect to Exchangeable Shares declared or
made after the Closing Time and with a record date after the Closing Time will
be paid to the holder of any unsurrendered Certificate with respect to the
Exchangeable Shares represented thereby until the holder of record of such
Certificate shall surrender such Certificate. Subject to applicable law,
following surrender of any such Certificate, there shall be paid to the record
holder of the certificates representing whole Exchangeable Shares issued in
exchange therefor, without interest, at the time of such surrender, the amount
of dividends or other distributions with a record date after the Closing Time
theretofore payable with respect to such whole number of Exchangeable Shares.

<PAGE>   14

               (e)    Transfers of Ownership. If any certificate for
Exchangeable Shares is to be issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it will be a
condition of the issuance thereof that the Certificate so surrendered will be
properly endorsed and shall otherwise appear in proper form for transfer and
that the person requesting such exchange will have paid to BackWeb Parent or any
agent designated by it any transfer or other taxes required by reason of the
issuance of a certificate for Exchangeable Shares in any name other than that of
the registered holder of the Certificate surrendered, or established to the
satisfaction of BackWeb Parent or any agent designated by it that such tax has
been paid or is not payable.

               (f)    No Liability. Notwithstanding anything to the contrary in
this Section 1.10, none of the Exchange Agent, the Surviving Corporation or any
party hereto shall be liable to a holder of Lanacom Common Shares for any amount
properly paid to a public official pursuant to any applicable abandoned
property, escheat or similar law.

        1.11   No Further Ownership Rights in Lanacom Common Shares. All Class A
Shares issued upon the Amalgamation in exchange for Lanacom Common Shares in
accordance with the terms hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to such Lanacom Common Shares, and there
shall be no further registration of transfers on the records of the Surviving
Corporation of Lanacom Common Shares which were outstanding immediately prior to
the Closing Time. If, after the Closing Time, Certificates are presented to the
Surviving Corporation for any reason, they shall be canceled and exchanged as
provided in this Article I (subject to the escrow provisions of Article VII).

        1.12   Lost, Stolen or Destroyed Certificates. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
make payment in exchange for such lost, stolen or destroyed Certificates, upon
the making of an affidavit in a form satisfactory to BackWeb Parent and the
Exchange Agent of that fact by the holder thereof, such amount as may be
required pursuant to Section 1.5; provided, however, that BackWeb Parent may, in
its sole discretion and as a condition precedent to the issuance thereof,
require the owner of any such lost, stolen or destroyed Certificates to deliver
a bond in such sum as BackWeb Parent may reasonably direct as indemnity against
any claim that may be made against BackWeb Parent, the Surviving Corporation or
the Exchange Agent with respect to the Certificates alleged to have been lost,
stolen or destroyed.

        1.13   BackWeb Parent Special Voting Share.

               (a)    Prior to the Closing Time, BackWeb Parent shall amend its
Articles of Association to create the BackWeb Special Preferred Share (the
"Special Voting Share") having the terms and conditions set out in Exhibit C.

               (b)    Immediately following the Amalgamation and
contemporaneously with the filing of the Articles of Reorganization in
accordance with subsection 1.5(c), BackWeb Parent shall issue one Special Voting
Share to The Trust Company of the Bank of Montreal as trustee to be held by it
in trust for the benefit of the holders from time to time of Exchangeable Shares
(other than BackWeb Parent)



                                       -9-
<PAGE>   15

in accordance with the provisions of the Voting and Exchange Trust Agreement (as
defined in Section 1.17 hereof).

        1.14   Taking of Necessary Action; Further Action. If, at any time after
the Closing Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of Lanacom and BackWeb Canada or to vest BackWeb Parent with
control in the Surviving Corporation, the officers and directors of the
Surviving Corporation are fully authorized in the name of the Surviving
Corporation or otherwise to take, and will take, all such lawful and necessary
and/or desirable action so long as such action is consistent with this
Agreement.

        1.15   Accounting Treatment. The Amalgamation is intended to be
accounted for by BackWeb Parent using the purchase method of accounting in
accordance with United States generally accepted accounting principles ("US
GAAP").

        1.16   Support Agreement between BackWeb Parent and the Surviving
Corporation. Immediately following the Amalgamation, BackWeb Parent and the
Surviving Corporation shall enter into a Support Agreement substantially in the
form attached hereto as Exhibit D (the "Support Agreement"), pursuant to which
BackWeb Parent shall agree among other things and subject to certain conditions,
to issue one BackWeb Parent Ordinary Share in exchange for each Surviving
Corporation Exchangeable Share. For so long as any Exchangeable Shares remain
outstanding, the parties agree to comply with all of the terms of the Support
Agreement and not to amend the Support Agreement without the written consent of
the Agent (as defined in Section 7.2(f)).

        1.17   Voting and Exchange Trust Agreement. Immediately following the
Amalgamation, BackWeb Parent, the Surviving Corporation and the trustee
thereunder shall enter into a Voting and Exchange Trust Agreement substantially
in the form attached hereto as Exhibit E (the "Voting and Exchange Trust
Agreement"), providing for the exercise of voting rights in BackWeb Parent by
holders of Exchangeable Shares and certain other matters.

                                   ARTICLE II

            REPRESENTATIONS AND WARRANTIES OF LANACOM AND THE FOUNDER

does not, and the consummation of the transactions contemplated hereby will not,
conflict with, or result in any violation of, or default under (with or without
notice or lapse of time, or both), or give rise to a right of termination,
cancellation or acceleration of any obligation or loss of any benefit under (any

        5.12   Bring Along Rights. On or prior to November 1, 1997, Anthony
Davis shall become a party to that certain Amended and Restated Shareholders
Agreement of BackWeb Parent dated as of December 9, 1996, as a Shareholder
thereunder, and as such shall be subject to the provisions of Section 2 (Bring
Along Rights) thereof. Mr. Davis shall not be a "Founder" or "Major Holder"
under such agreement. As a condition to Mr. Davis becoming subject to such
agreement, the agreement shall be amended by the Shareholders thereunder to
permit the inclusion of Mr. Davis within such agreement. The parties shall also
use all commercially reasonable efforts to include other Major Shareholders of
Lanacom as Shareholders under such agreement on similar terms as Mr. Davis.

        5.13   Registration Rights. The parties agree to use their commercially
reasonable efforts to have that certain Amended and Restated Rights Agreement
(the "Rights Agreement") by and among BackWeb Parent and the Purchasers thereto
amended on or prior to November 1, 1997 in order to provide to all of the
holders of Exchangeable Shares (the "Rights Holders") registration rights
pertaining to the BackWeb Parent Ordinary Shares issuable pursuant to their
Exchangeable Shares, which registration rights shall be substantially similar to
those granted to the Series B and Series C Holders (as defined in the Rights
Agreement), except as described herein. If the parties are unable, after
solicitation of all of the Rights Holders, to cause such amendment of the Rights
Agreement to the benefit of holders of at least 75% of the Exchangeable Shares
earned in connection with the Acquisition on or prior to November 1, 1997
(including obtaining necessary consents from existing holders of registration
rights and acceptance of such rights from Lanacom Holders), BackWeb Parent shall
enter into a separate registration rights agreement with the Rights Holders,
which separate agreement shall provide to the Rights Holders registration rights
substantially similar to those granted to the Series B and the Series C Holders
under the Rights Agreement, except as described herein. The agreement providing
the Rights Holders with their registration rights under this Section 5.12 shall
provide, inter alia, that the number of BackWeb Parent Ordinary Shares required
to exercise a demand registration right shall be no higher



                                      -37-
<PAGE>   43

than the number equal to two-thirds of the number of Exchangeable Shares
provided to the Rights Holders under this Agreement and entitled to such
registration rights, and that demand rights may be exercised at any time at
least 6 months following an initial public offering of BackWeb Parent, subject
only to normal blackout periods generally applicable to holders of BackWeb
registration rights which shall not exceed 6 months in duration. It is
understood that in the event that the Rights Holders shall be able to utilize
the Closing Date of the Acquisition (upon which date they shall receive the
Exchangeable Shares) as the original purchase date with respect to the BackWeb
Parent Ordinary Shares that such holders ultimately receive in respect of such
Exchangeable Shares, for the purposes of the holding period requirement set
forth in Rule 144 under the Securities Exchange Act of 1993, as amended (other
than any inability to use such Closing Date as original purchase date for the
purposes of Rule 144 solely due to an action taken by the holder thereof, such
as a pledge of shares, which tolls the holding period under Rule 144), then the
right of the Rights Holders to include shares in any registration as to which
they exercise registration rights shall be subordinate to the registration
rights of other holders of registration rights. In this regard, in the event
that the underwriters of an offering determine that marketing restrictions
require a limitation in the number of shares to be included in the offering on
behalf of holders of registration rights, then other holders of registration
rights shall be entitled to include the full number of shares in such
registration and offering desired by them before inclusion of shares in such
registration and offering on the part of the Rights Holders.

<PAGE>   47

survive until the Second Escrow Release Date (as defined below), except that the
representations and warranties contained in (a) Sections 2.7 and 2.17 shall
survive until the expiration of all applicable statutes of limitation (the
"Statutory Periods") and (b) Section 2.2 shall survive indefinitely.
Notwithstanding the foregoing, nothing contained in this Section 7.1 shall

representations and warranties of Lanacom shall terminate at the Closing Time.
The Founder waives any right to contribution or indemnity as against the

        7.2    Escrow Arrangements.

               (a)    Escrow Fund. As soon as practicable after the Closing,
that number of Exchangeable Shares comprising the Escrow Amount will be
deposited by the Surviving Corporation, without any act of any Holder in Escrow,
with Bank of Montreal Trust Company (or another institution acceptable to
BackWeb Parent and the Agent (as defined in Section 7.2(f) below)) as Escrow
Agent (the "Escrow Agent"), such deposit to constitute an escrow fund (the
"Escrow Fund") to be governed by the terms set forth herein. The Escrow Amount
contributed on behalf of any Holder in Escrow shall be a fraction of the total
Escrow Amount equal to such Holder's Proportional Escrow Amount, and shall be
deducted from the portion of the Amalgamation Consideration to which such holder
of Lanacom Common Shares would otherwise be entitled to receive pursuant to
Section 1.5. A list of the respective Escrow Amounts contributed by the Holders
shall be provided to the Escrow Agent. The Escrow Amount deposited in the Escrow
Fund shall be used effectively to reduce the Amalgamation Consideration in the
event of (y) a reduction required pursuant to Section 1.7 of this Agreement and
(z) any claim, loss, expense, liability or other damage, including reasonable
attorneys' fees, to the extent of the amount of such claim, loss, expense,
liability or other damage (collectively with any amounts payable pursuant to
Section 1.7, the "Losses") that BackWeb Parent or any of its affiliates have
incurred by reason of the breach by Lanacom of any representation, warranty,
covenant or agreement of Lanacom contained in this Agreement. BackWeb Parent,
Lanacom and the Agent each acknowledge that such Losses, if any, shall be deemed
to relate to unresolved contingencies existing at the Closing Date which, if
resolved at the Closing Date, would have led to a reduction in the Amalgamation
Consideration. Nothing herein shall limit the liability of Lanacom, the Founder
or any holder of Lanacom Common Shares for any breach of any covenant, or any
willful breach of any representation or warranty, if the Amalgamation does not
close. In addition, notwithstanding the foregoing, the Surviving Corporation
shall not be entitled to receive any Escrow Amounts from the Escrow Fund unless
and until Officer's Certificates (as defined in paragraph (d) below) identifying
Losses, the aggregate amount of which exceed an aggregate US_______ deductible
amount, have been delivered to the Escrow Agent as provided in paragraph (d); in
such case the Escrow Agent shall deliver to the Surviving Corporation for
cancellation for no consideration, and in full satisfaction of the aggregate
claims of BackWeb Parent (or its affiliates) the number of Exchangeable Shares
remaining in the Escrow Fund having an aggregate value (based on the value of
the Exchangeable Shares on the Closing Date of US_____ per share) equal to
one-third of the aggregate amount of such Losses (reflecting the parties'
agreement that one-third of the risk of such event shall be borne by the
shareholders of Lanacom and two-thirds of the risk shall be borne by BackWeb
Parent) minus the one time aggregate deductible amount of US_______.

               (b)    Escrow Period; Distribution upon the First and Second
Escrow Release Dates. Subject to the requirements set forth in this Section
7.2(b), the Escrow Fund shall remain in existence immediately following the
Closing Time and shall terminate at 5:00 p.m., California Time on the Second
Escrow Release Date (as defined below). As used herein "First Escrow Release
Date" shall mean the earlier of (i) the date thirty (30) days after the date of
delivery by BackWeb Parent's independent auditors to BackWeb Parent of signed,
audited consolidated financial statements for the BackWeb Parent fiscal year
ended December 31, 1997 and (ii) May 1, 1998. BackWeb Parent shall notify the
Escrow Agent in writing of the establishment of the First Release Date. As used
herein "Second Escrow Release Date" shall mean the date being six months after
the First Escrow Release Date. The First Escrow Release Date and the Second
Escrow Release Date are referred to herein collectively as the "Escrow Release
Dates." On the First Escrow Release Date, a portion of the Escrow Fund shall be
released from escrow to the Holders in Escrow as reasonably practicable in
proportion to their respective Proportionate Escrow Interest in an amount equal
to one half of the entire Escrow Amount, less any Holdover Amount (as defined
below). On the Second Escrow Release Date, a portion of the Escrow Fund shall be
released from escrow to the Holders in Escrow as reasonably practicable in
proportion to their respective Proportionate Escrow Interest in an amount equal
to the entire Escrow Amount then remaining in the Escrow Fund less any Holdover
Amount. As soon as all claims relating to a Holdover Amount have been resolved,
the Escrow Agent shall deliver to the appropriate Holders in Escrow the
remaining portion of the Escrow Fund not required to satisfy such claims and the
Escrow Fund shall be terminated. Deliveries of Escrow Amounts from the Escrow
Fund to the Holders in Escrow pursuant to this Section 7.2(b) shall be made in
proportion to their respective Proportionate Escrow Interest as reasonably
practicable. As used herein "Holdover Amount" shall mean (y) any amounts
previously returned for cancellation to the Surviving Corporation including,
without limitation, such amounts returned pursuant to Section 1.7 of this
Agreement and (z) any additional amount which, in the reasonable judgment of
BackWeb Parent, subject to the objection of the Agent and subsequent arbitration
of the matter in the manner provided in Section 7.2(e) hereof, is necessary to
satisfy any unsatisfied claims specified in any Officer's Certificate delivered
to the Escrow Agent prior to the applicable Escrow Release Date (which amount
shall remain in the Escrow Fund until such claims have been resolved). If any
Holdover Amount shall exist on the Second Escrow Release Date, such Holdover
Amount shall cause the Escrow Fund to remain in existence until such claims have
been resolved.

               (c)    Protection of Escrow Fund. The Escrow Agent shall hold and
safeguard the Escrow Fund during the period that the Escrow Fund remains in
existence, shall treat such fund as a trust fund in accordance with the terms of
this Agreement and not as the property of BackWeb Parent and shall hold and
dispose of the Escrow Fund only in accordance with the terms hereof. The Holders
in Escrow shall be treated as the owners of the Escrow Fund for all purposes,
subject to the rights of BackWeb Parent and the Surviving Corporation under this
Agreement.

               (d)    Claims Upon Escrow Fund; Distributions; Voting;
Conversion.

                      (i)    Upon receipt by the Escrow Agent at any time on or
before the Second Escrow Release Date of a certificate signed by any officer of
BackWeb Parent (an "Officer's Certificate"): (A) stating that BackWeb Parent has
paid or properly accrued or reasonably anticipates that it will have to pay or
accrue Losses, and (B) specifying in reasonable detail the individual items of



                                      -43-
<PAGE>   49
Losses included in the amount so stated, the date each such item was paid or
properly accrued, or the basis for such anticipated liability, and the nature of
the misrepresentation, breach of warranty or claim to which such item is
related, the Escrow Agent shall, subject to the provisions of Section
7.2(d)(iii), deliver to the Surviving Corporation for cancellation for no
consideration that number of Exchangeable Shares specified in the Officer's
Certificate, which shall be those Exchangeable Shares remaining in the Escrow
Fund having an aggregate value (based on the value of the Exchangeable Shares on
the Closing Date of US$______ per share) equal to _________ of the amount of
such Losses (reflecting the parties' agreement that _________ of the risk of
such event shall be borne by the shareholders of Lanacom and two-thirds of the
risk shall be borne by BackWeb Parent) claimed less the aggregate US$_________
deductible amount (or, to the extent the deductible has been previously applied,
less any remaining portion of such aggregate US$______ deductible), all as
calculated by BackWeb Parent and set forth in the Officer's Certificate. The
Escrow Agent shall have no duty or obligation to verify the information or
calculations provided to it in such Officer's Certificate.

                      (ii)   [intentionally left blank]

                      (iii)  At the time of delivery of any Officer's
Certificate to the Escrow Agent, a duplicate copy of such Officer's Certificate
shall be delivered to the Agent (as defined in Section 7.2(f)), and for a period
of thirty (30) days after such delivery to the Escrow Agent, it shall make no
delivery to the Surviving Corporation of any Escrow Amounts pursuant to Section
7.2(b) hereof unless the Escrow Agent shall have received written authorization
from the Agent to make such delivery. After the expiration of such thirty (30)
day period, the Escrow Agent shall make delivery of an amount from the Escrow
Fund in accordance with Section 7.2(b) hereof, provided that no such payment or
delivery may be made if the Agent shall object in a written statement to the
claim made in the Officer's Certificate, and such statement shall have been
delivered to the Escrow Agent prior to the expiration of such thirty (30) day
period.

                      (iv)   Any Exchangeable Shares or other equity securities
issued or distributed in respect of the Exchangeable Shares (including shares
issued upon a stock split) (collectively, "New Shares") in respect of
Exchangeable Shares which have not been released from the Escrow Fund shall be
added to the Escrow Fund and shall become part of the Escrow Amount for all
purposes of this Article VII. All cash dividends, if any, paid on Exchangeable
Shares, shall be paid to the holders of Exchangeable Shares in accordance with
their respective contributions to the Escrow Fund.

                      (v)    Each holder of Exchangeable Shares shall have all
voting and other contractual rights with respect to Exchangeable Shares
contributed to the Escrow Fund on behalf of any such holder (and any New Shares
having voting rights) so long as such Exchangeable Shares or other voting
securities are held in the Escrow Fund, except to the extent that BackWeb Parent
and the Agent agree in writing.

                      (vi)   None of the Exchangeable Shares in the Escrow Fund
shall be exchanged for BackWeb Parent Ordinary Shares while in the Escrow Fund,
except to the extent that BackWeb Parent and the Agent agree in writing, in
their discretion, provided that in such event the BackWeb Parent Ordinary Shares
issued in respect of such Exchangeable Shares shall be placed into escrow under



                                      -44-
<PAGE>   50

the terms and conditions hereof. A copy of such agreement, together with a joint
letter of instruction, shall be delivered to the Escrow Agent directing it as to
any exchange.

                      (vii)  Notwithstanding any of the foregoing in this
Article VII, the procedures in Sections 7.2(d)(i) and (iii) above shall be
deemed inapplicable in the case of claims made against the Escrow pursuant to
Section 1.7 of this Agreement. In such case, upon BackWeb Parent's presentation
to the Escrow Agent of an Officer's Certificate, within five (5) days following
the receipt of such Officer's Certificate, the Escrow Agent shall cause to be
distributed to the Surviving Corporation for cancellation for no consideration
that number of Exchangeable Shares as specified in the Officer's Certificate,
which shall be based upon the Final Balance Sheet containing the Accountants'
final determination of a Final Net Asset Value more negative than US$_________
and more negative than the Preliminary Net Asset Value, as determined pursuant
to Section 1.7(b) hereof.

               (e)    Resolution of Conflicts; Arbitration.

                      (i)    In case the Agent shall so object in writing to any
claim or claims made in any Officer's Certificate, the Agent and BackWeb Parent
shall attempt in good faith to agree upon the rights of the respective parties
with respect to each of such claims. If the Agent and BackWeb Parent should so
agree, a memorandum setting forth such agreement shall be prepared and signed by
both parties and shall be furnished to the Escrow Agent. The Escrow Agent shall
be entitled to rely on any such memorandum and distribute amounts from the
Escrow Fund in accordance with the terms thereof.

                      (ii)   If no such agreement can be reached after good
faith negotiation, either BackWeb Parent or the Agent may demand arbitration of
the matter unless the amount of the damage or loss is at issue in pending
litigation with a third party, in which event arbitration shall not be commenced
until such amount is ascertained or both parties agree to arbitration; and in
either such event the matter shall be settled by arbitration conducted by three
arbitrators. BackWeb Parent and the Agent shall each select one arbitrator, and
the two arbitrators so selected shall select a third arbitrator. The arbitrators
shall set a limited time period and establish procedures designed to reduce the
cost and time for discovery while allowing the parties an opportunity, adequate
in the sole judgement of the arbitrators, to discover relevant information from
the opposing parties about the subject matter of the dispute. The arbitrators
shall rule upon motions to compel or limit discovery and shall have the
authority to impose sanctions, including attorneys fees and costs, to the extent
as a court of competent law or equity, should the arbitrators determine that
discovery was sought without substantial justification or that discovery was
refused or objected to without substantial justification. The decision of a
majority of the three arbitrators as to the validity and amount of any claim in
such arbitration award shall be binding and conclusive upon the parties to this
Agreement. BackWeb Parent shall deliver to the Escrow Agent a copy of such
arbitration award together with an Officer's Certificate directing the Escrow
Agent to comply with such arbitration award and, notwithstanding anything in
Section 7.2(d) to the contrary, the Escrow Agent shall be entitled to act in
accordance with such decision and make or withhold payments out of the Escrow
Fund in accordance therewith. Such decision shall be written and shall be
supported by written findings of fact and conclusions which shall set forth the
award, judgment, decree or order awarded by the arbitrators.



                                      -45-
<PAGE>   51

                      (iii)  Judgment upon any award rendered by the arbitrators
may be entered in any court having jurisdiction. Any such arbitration shall be
held in Santa Clara County, California, under the rules then in effect of the
American Arbitration Association. For purposes of this Section 7.2(e), in any
arbitration hereunder in which any claim or the amount thereof stated in the
Officer's Certificate is in dispute, BackWeb Parent shall be deemed to be the
"Non-Prevailing Party" in the event that the arbitrators award BackWeb Parent
less than the sum of one-half (1/2) of the disputed amount; otherwise, the
holders of Exchangeable Shares as represented by the Agent shall be deemed to
be the Non-Prevailing Party. The Non-Prevailing Party to an arbitration shall
pay its own expenses, the fees of each arbitrator, the administrative fee of the
American Arbitration Association, and the expenses, including without
limitation, reasonable attorneys' fees and costs, incurred by the other party to
the arbitration.

                      (iv)   Notwithstanding any of the foregoing, the disputes
arising in connection with provisions set forth in Sections 7.2(e)(i)-(iii)
above, which provisions include, without limitation, procedures for conflicts
resolution and arbitration, shall be deemed inapplicable in the case of claims
made against the Escrow pursuant to Section 1.9 of this Agreement. In such case,
Section 1.7(c) shall govern. The Escrow Agent shall not be responsible, nor
shall it have any duty or obligation to determine, under which Section hereof
has been made or may arise under.

               (f)    Agent of the Stockholders; Power of Attorney.

                      (i)    In the event that the Amalgamation is approved,
effective upon such vote, and without further act of any shareholder, Anthony
Davis shall be appointed as agent and attorney-in-fact (the "Agent") for each
Holder in Escrow, to give and receive notices and communications, to authorize
delivery to BackWeb Parent of Exchangeable Shares from the Escrow Fund in
satisfaction of claims by BackWeb Parent, to object to such deliveries, to agree
to, negotiate, enter into settlements and compromises of, and demand arbitration
and comply with orders of courts and awards of arbitrators with respect to such
claims, and to take all actions necessary or appropriate in the judgment of
Agent for the accomplishment of the foregoing. Such agency may be changed by the
Holders in Escrow from time to time upon not less than thirty (30) days prior
written notice to BackWeb Parent and the Escrow Agent; provided that the Agent
may not be removed unless holders of a two-thirds interest of the Escrow Fund
agree to such removal and to the identity of the substituted agent. The Agent
may resign from such agency at any time upon written notice to BackWeb Parent
and the Escrow Agent, whereupon holders of not less than a two-thirds interest
in the Escrow Fund shall promptly appoint a replacement Agent and shall notify
BackWeb Parent and the Escrow Agent in writing of any replacement Agent. No bond
shall be required of the Agent, and the Agent shall not receive compensation for
his or her services. Notices or communications to or from the Agent shall
constitute notice to or from each of the Holders in Escrow.

                      (ii)   The Agent shall not be liable for any act done or
omitted hereunder as Agent except to the extent the Agent acts in bad faith or
is grossly negligent. The Holders in Escrow on whose behalf the Escrow Amount
was contributed to the Escrow Fund shall severally indemnify the Agent and hold
the Agent harmless against any loss, liability or expense incurred without
negligence or bad faith on the part of the Agent and arising out of or in
connection with the acceptance or administration of the Agent's duties
hereunder, including the reasonable fees and expenses of any legal



                                      -46-
<PAGE>   52

counsel retained by the Agent. The Agent shall be entitled to make payment from
the Escrow Fund of all expenses, including reasonable fees and expenses of any
such legal counsel, incurred by the Agent in connection with the acceptance or
administration of the Agent's duties hereunder.

                      (iii)  A decision, act, consent or instruction of the
Agent shall constitute a decision of all the Holders in Escrow and shall be
final, binding and conclusive upon each of such shareholders, and the Escrow
Agent and BackWeb Parent may rely upon and shall be fully protected in relying
upon any such decision, act, consent or instruction of the Agent as being the
decision, act, consent or instruction of each every such Holder in Escrow. The
Escrow Agent and BackWeb Parent are hereby relieved from any liability to any
person for any acts done by them in accordance with such decision, act, consent
or instruction of the Agent.

               (g)    Third Party Claims.

                      (i)    In the event BackWeb Parent becomes aware of a
third party claim which BackWeb Parent believes may result in a demand against
the Escrow Fund, BackWeb Parent shall notify the Agent of such claim, and the
Agent and the Holders in Escrow shall be entitled, at their expense, to
participate in any defense of such claim. BackWeb Parent shall consult with the
Agent prior to settlement of any such claim and discuss with the Agent in good
faith any input regarding the claim and potential settlement the Agent may have
prior to any settlement. After such consultation, BackWeb Parent shall have the
right to settle any such claim; provided, however, that except with the consent
of the Agent (which shall not be unreasonably withheld), no settlement of any
such claim with third-party claimants shall alone be determinative of the amount
of any claim against the Escrow Fund. In the event that the Agent has consented
to any such settlement, the Agent shall have no power or authority to object
under any provision of this Article VII to the amount of any claim by BackWeb
Parent against the Escrow Fund with respect to such settlement.

                      (ii)   If any claim is asserted against BackWeb Parent or
its affiliates that the use of HeadLiner software by Lanacom, BackWeb Parent or
any of their licensed customers infringes or otherwise violates the copyright
(or author's and moral rights) of a third party in any content located on a
Website accessed by such software, then BackWeb Parent shall use its
commercially reasonable efforts to obtain permission or a license from the owner
or holder of such copyright (or author's and moral right) to allow the software
to access such content. In the event that such permission or license is not
granted, BackWeb Parent agrees that it shall to the extent commercially
reasonable (i) de-list the relevant Website(s) from the software's directory
list, (ii) stop using the software to access the relevant Website(s) and/or
(iii) prevent its licensed customers from accessing such Websites. Such efforts
could include without limitation (to the extent commercially reasonable)
notifying licensed customers of prohibited Websites and making minor
modifications to the software to prevent such access. BackWeb Parent agrees that
it will consult with Founder in respect of such copyright issues as they arise
and will attempt to the extent commercially reasonable to settle any litigation
commenced by such parties regarding such issues as efficiently as possible in
light of the circumstances.

               (h)    Escrow Agent's Duties.

                      (i)    The Escrow Agent shall be obligated only for the
performance of such duties as are specifically set forth in this Article VII,
and as set forth in any additional written escrow instructions which the Escrow
Agent may receive after the date of this Agreement which are signed by an
officer of BackWeb Parent and the Agent, and no implied duties or obligations
shall be read into this Agreement against the Escrow Agent. The Escrow Agent may
rely and shall be protected in relying or refraining from acting on any
instrument, instruction, notice or other document reasonably believed to be
genuine and to have been signed or presented by the proper party or parties. The
Escrow Agent shall not be liable for any act done or omitted hereunder as Escrow
Agent while acting in good faith and in the exercise of reasonable judgment, and
any act done or omitted pursuant to the advice of counsel shall be conclusive
evidence of such good faith.

                      (ii)   The Escrow Agent is hereby expressly authorized to
disregard any and all warnings of judicial proceedings or similar actions given
by any of the parties hereto or by any other person, excepting only orders or
process of courts of law, and is hereby expressly authorized to comply with and
obey orders, judgments or decrees of any court. In case the Escrow Agent obeys
or complies with any such order, judgment or decree of any court, the Escrow
Agent shall not be liable to any of the parties hereto or to any other person by
reason of such compliance, notwithstanding any such order, judgment or decree
being subsequently reversed, modified, annulled, set aside, vacated or found to
have been entered without jurisdiction.

                      (iii)  The Escrow Agent shall not be liable in any respect
on account of the identity, authority or rights of the parties executing or
delivering or purporting to execute or deliver this Agreement or any documents
or papers deposited or called for hereunder.

                      (iv)   The Escrow Agent shall not be liable for the
expiration of any rights under any statute of limitations with respect to this
Agreement or any documents deposited with the Escrow Agent.

                      (v)    In performing any duties under the Agreement, the
Escrow Agent shall not be liable to any party for damages, losses, or expenses,
except for gross negligence or willful misconduct on the part of the Escrow
Agent. The Escrow Agent shall not incur any such liability for (A) any act or
failure to act made or omitted in good faith, or (B) any action taken or omitted
in reliance upon any instrument, instruction, notice or other document,
including any written statement of affidavit provided for in this Agreement that
the Escrow Agent shall in good faith believe to be genuine, nor will the Escrow
Agent be liable or responsible for forgeries, fraud, impersonations, or
determining the scope of any representative authority. In addition, the Escrow
Agent may consult with the legal counsel in connection with Escrow Agent's
duties under this Agreement and shall be fully protected in any act taken,
suffered, or permitted by him/her in good faith in accordance with the advice of
counsel. The Escrow Agent is not responsible for determining and verifying the
authority of any person acting or purporting to act on behalf of any party to
this Agreement.


                                      -48-
<PAGE>   54

                      (vi)   If any controversy arises between the parties to
this Agreement, or with any other party, concerning the subject matter of this
Agreement, its terms or conditions, the Escrow Agent will not be required to
determine the controversy or to take any action regarding it. The Escrow Agent
may hold all documents and shares of Surviving Corporation Exchangeable Shares
and may wait for settlement of any such controversy by final appropriate legal
proceedings or other means as, in the Escrow Agent's discretion, the Escrow
Agent may be required, despite what may be set forth elsewhere in this
Agreement. In such event, the Escrow Agent will not be liable for damage.

                      Furthermore, the Escrow Agent may at its option, file an
action of interpleader requiring the parties to answer and litigate any claims
and rights among themselves. The Escrow Agent is authorized to deposit with the
clerk of the court all documents and shares of Surviving Corporation
Exchangeable Shares held in escrow, except all cost, expenses, charges and
reasonable attorney fees incurred by the Escrow Agent due to the interpleader
action and which the Escrow Agent may recoup directly from the Escrow Fund. Upon
initiating such action, the Escrow Agent shall be fully released and discharged
of and from all obligations and liability imposed by the terms of this
Agreement.

                      (vii)  The parties and their respective successors and
assigns agree jointly and severally to indemnify and hold Escrow Agent harmless
against any and all losses, claims, damages, liabilities, and expenses,
including reasonable costs of investigation, counsel fees, and disbursements
that may be imposed on Escrow Agent or incurred by Escrow Agent in connection
with the performance of his/her duties under this Agreement, including but not
limited to any litigation arising from this Agreement or involving its subject
matter, such indemnity to be satisfied directly from the Escrow Fund. This right
of indemnification shall survive the termination of this Agreement and the
resignation or removal of the Escrow Agent. The costs and expenses of enforcing
this right of indemnification shall also be paid by the parties.

                      (viii) The Escrow Agent may resign at any time upon giving
at least thirty (30) days written notice to BackWeb Parent and the Agent;
provided, however, that no such resignation shall become effective until the
appointment of a successor escrow agent which shall be accomplished as follows:
BackWeb Parent and Agent shall use their best efforts to mutually agree on a
successor escrow agent within thirty (30) days after receiving such notice. If
the parties fail to agree upon a successor escrow agent within such time,
BackWeb Parent shall have the right to appoint a successor escrow agent
authorized to do business in the Province of Ontario, Canada. The successor
escrow agent shall execute and deliver an instrument accepting such appointment
and it shall, without further acts, be vested with all the estates, properties,
rights, powers, and duties of the predecessor escrow agent as if originally
named as escrow agent. The Escrow Agent shall be discharged from any further
duties and liability under this Agreement.

                      (ix)   The Escrow Agent's duties shall be determined only
with reference to this Article VII and are not changed with any duty, obligation
or responsibility in connection with any other Article in this Agreement, nor
with any other document or agreement.

               (i)    Exclusivity of Remedies. Resort to the provisions of this
Article VII and Section 1.7 providing for the delivery of Exchangeable Shares to
the Surviving Corporation for cancellation from



                                      -49-
<PAGE>   55

the Escrow Fund shall be BackWeb Parent's (and its affiliates') exclusive remedy
for any Losses, except for Losses resulting from breaches of representations and
warranties contained in Sections 2.2, 2.7 and 2.17 of this Agreement and Losses
resulting from fraud (collectively, the "Special Losses"). The parties agree
that BackWeb Parent shall be able to recover from Founder Holdco for all Special
Losses, including any Losses above the Escrow Amount, during the applicable
survival period set forth in Section 7.1 hereof; provided however, that Founder
Holdco's aggregate liability with respect to all Special Losses (including
Founder Holdco's proportionate share of any amounts paid to BackWeb Parent out
of the Escrow Fund) shall not exceed the total Amalgamation Consideration
received by Founder Holdco (including Exchangeable Shares placed in Escrow
pursuant to the provisions of Section 1.9 and Article VII). The Founder agrees
that until such time as the Escrow Fund shall have been terminated in accordance
with Section 7.2(b), the Founder will remain the owner of all right, title and
interest in and to all of the outstanding shares of Founder Holdco, that Founder
Holdco will remain the owner of all right, title and interest in and to all of
the Exchangeable Shares delivered to it under this Agreement, that Founder
Holdco shall not effect any borrowings or incur any liabilities other than
potential liabilities to BackWeb Parent or BackWeb Canada under this Agreement
and that Founder Holdco will not be used for any purpose other than as
contemplated by this Agreement. The parties hereto agree that the Founder shall
not be personally liable for any breach of this Agreement (except for a breach
of the preceding sentence which actually reduces the ability of the Surviving
Corporation or BackWeb Parent to recover Exchangeable Shares for cancellation
which it would have otherwise been entitled to recover under this Agreement, and
in such circumstances only to the extent of such actual reduction) and that
(except for any breach of the preceding sentence) recourse to the Escrow Fund or
to Founder Holdco in accordance with this Section 7.2(i) shall be BackWeb
Parent's (and its affiliates') exclusive remedy hereunder.

                                  ARTICLE VIII

                        CERTAIN RIGHTS OF BACKWEB PARENT
                         TO ACQUIRE EXCHANGEABLE SHARES

        8.1    BackWeb Parent Liquidation Call Right.

               (a)    BackWeb Parent shall have the overriding right (the
"Liquidation Call Right"), in the event of and notwithstanding the proposed
liquidation, dissolution or winding-up of the Surviving Corporation pursuant to
Article 5 of the provisions of the Exchangeable Shares (the "Exchangeable Share
Provisions") to purchase from all but not less than all of the holders of
Exchangeable Shares on the Liquidation Date (as defined in the Exchangeable
Share Provisions) all, but not less than all of the Exchangeable Shares held by
each such holder on payment by BackWeb Parent of an amount per Exchangeable
Share equal to (a) the Current Market Price (as defined in the Exchangeable
Share Provisions) of a BackWeb Parent Ordinary Share on the last Business Day
prior to the Liquidation Date, which shall be satisfied in full by causing to be
delivered to such holder one BackWeb Parent Ordinary Share, plus (b) an
additional amount equivalent to the full amount of all dividends declared and
unpaid on such Exchangeable Share and all dividends declared on BackWeb Parent
Ordinary Shares which have not been declared on such Exchangeable Shares in
accordance with section 7.1 of the Exchangeable Share Provisions (collectively
the "Liquidation Call Purchase Price"), provided that if the record date for any
such declared and unpaid dividends occurs on or after the Liquidation Date, the
Liquidation Call Price shall not include such additional amount equivalent to
such dividends. In the event of the exercise of the Liquidation Call Right by
BackWeb Parent, each holder shall be obligated to sell all the Exchangeable
Shares held by the holder to BackWeb Parent on the Liquidation Date on payment
by BackWeb Parent to the holder of the Liquidation Call Purchase Price for each
such Exchangeable Share.

               (b)    To exercise the Liquidation Call Right, BackWeb Parent
must notify the Surviving Corporation's transfer agent (the "Transfer Agent"),
as agent for the holders of Exchangeable Shares, and the Surviving Corporation
of BackWeb Parent's intention to exercise such right at least 30 days before the
Liquidation Date in the case of a voluntary liquidation, dissolution or winding
up of the Surviving Corporation and at least five Business Days before the
Liquidation Date in the case of an involuntary liquidation, dissolution or
winding up of the Surviving Corporation. The Transfer Agent will notify the
holders of Exchangeable Shares as to whether or not BackWeb Parent has exercised
the Liquidation Call Right forthwith after the expiry of the period during which
the same may be exercised by BackWeb Parent. If BackWeb Parent exercises the
Liquidation Call Right, on the Liquidation Date BackWeb Parent will purchase and
the holders will sell all of the Exchangeable Shares then outstanding for a
price per Exchangeable Share equal to the Liquidation Call Purchase Price.

               (c)    For the purposes of completing the purchase of the
Exchangeable Shares pursuant to the Liquidation Call Right, BackWeb Parent shall
deposit with the Transfer Agent, on or before the Liquidation Date, certificates
representing the aggregate number of BackWeb Parent Ordinary Shares deliverable
by BackWeb Parent in payment of the total Liquidation Call Purchase Price and a
cheque or cheques in the amount of the remaining portion, if any, of the total
Liquidation Call Purchase Price. Provided that the total Liquidation Call
Purchase Price has been so deposited with the Transfer Agent,



                                      -51-
<PAGE>   57

on and after the Liquidation Date the rights of each holder of Exchangeable
Shares will be limited to receiving such holder's proportionate part of the
total Liquidation Call Purchase Price payable by BackWeb Parent upon
presentation and surrender by the holder of certificates representing the
Exchangeable Shares held by such holder and the holder shall on and after the
Liquidation Date be considered and deemed for all purposes to be the holder of
the BackWeb Parent Ordinary Shares delivered to it. Upon surrender to the
Transfer Agent of a certificate or certificates representing Exchangeable
Shares, together with such other documents and instruments as may be required to
effect a transfer of Exchangeable Shares under the Act and the by-laws of the
Surviving Corporation and such additional documents and instruments as the
Transfer Agent may reasonably require, the holder of such surrendered
certificate or certificates shall be entitled to receive in exchange therefor,
and the Transfer Agent on behalf of BackWeb Parent shall deliver to such holder,
certificates representing the BackWeb Parent Ordinary Shares to which the holder
is entitled and a cheque or cheques of BackWeb Parent payable at par and in
Canadian dollars at any Canadian branch of the bankers of BackWeb Parent or of
the Surviving Corporation in Canada in payment of the remaining portion, if any,
of the total Liquidation Call Purchase Price. If BackWeb Parent does not
exercise the Liquidation Call Right in the manner described above, on the
Liquidation Date the holders of the Exchangeable Shares will be entitled to
receive in exchange therefor the liquidation price otherwise payable by the
Surviving Corporation in connection with the liquidation, dissolution or
winding-up of the Surviving Corporation pursuant to Article 5 of the
Exchangeable Share Provisions.

        8.2    BackWeb Parent Redemption Call Right.

               (a)    BackWeb Parent shall have the overriding right (the
"Redemption Call Right"), notwithstanding the proposed redemption of
Exchangeable Shares by the Surviving Corporation pursuant to Article 7 of the
Exchangeable Share Provisions, to purchase from all but not less than all of the
holders of Exchangeable Shares to be redeemed on the Redemption Date (as defined
in the Exchangeable Share Provisions) all but not less than all of the
Exchangeable Shares held by each such holder on payment by BackWeb Parent to the
holder of an amount per Exchangeable Share equal to (a) the Current Market Price
(as defined in the Exchangeable Share Provisions) of a BackWeb Parent Ordinary
Share on the last Business Day prior to the Redemption date, which shall be
satisfied in full by causing to be delivered to such holder one BackWeb Parent
Ordinary Share, plus (b) an additional amount equivalent to the full amount of
all dividends declared and unpaid on such Exchangeable Share in accordance with
section 7.1 of the Exchangeable Share Provisions (collectively the "Redemption
Call Purchase Price"), provided that if the record date for any such declared
and unpaid dividend occurs on or after the Redemption Date, the Redemption Call
Purchase Price shall not include such additional amount equivalent to such
dividends. In the event of the exercise of the Redemption Call Right by BackWeb
Parent, each holder shall be obligated to sell all the Exchangeable Shares held
by the holder and otherwise to be redeemed to BackWeb Parent on the Redemption
Date on payment by BackWeb Parent to the holder of the Redemption Call Purchase
Price for each such Exchangeable Share.

               (b)    To exercise the Redemption Call Right, BackWeb Parent must
notify the Transfer Agent, as agent for the holder of Exchangeable Shares, and
the Surviving Corporation of BackWeb Parent's intention to exercise such right
at least 20 days before the Automatic Redemption Date (as defined in



                                      -52-
<PAGE>   58

the Exchangeable Share Provisions), in the case of the Automatic Redemption (as
defined in the Exchangeable Share Provisions). The Transfer Agent will notify
the holders of the Exchangeable Shares as to whether or not BackWeb Parent has
exercised the Redemption Call Right forthwith after the expiry of the period
during which the same may be exercised by BackWeb Parent. If BackWeb Parent
exercises the Redemption Call Right, on the Redemption Date BackWeb Parent will
purchase and the holders will sell all of the Exchangeable Shares to be redeemed
for a price per Exchangeable Share equal to the Redemption Call Purchase Price.

               (c)    For the purposes of completing this purchase of
Exchangeable Shares pursuant to the Redemption Call Right, BackWeb Parent shall
deposit with the Transfer Agent, on or before the Redemption Date, certificates
representing the aggregate number of BackWeb Parent Ordinary Shares deliverable
by BackWeb Parent in payment of the total Redemption Call Purchase Price and a
cheque or cheques in the amount of the remaining portion, if any, of the total
Redemption Call Purchase Price. Provided that the total Redemption Call Purchase
Price has been so deposited with the Transfer Agent, on and after the Redemption
Date the rights of each holder of Exchangeable Shares so purchased will be
limited to receiving such holder's proportionate part of the total Redemption
Call Purchase Price payable by BackWeb Parent upon presentation and surrender by
the holder of certificates representing the Exchangeable Shares purchased by
BackWeb Parent from such holder and the holder shall on and after the Redemption
Date be considered and deemed for all purposes to be the holder of the BackWeb
Parent Ordinary Shares delivered to such holder. Upon surrender to the Transfer
Agent of a certificate or certificates representing Exchangeable Shares,
together with such other documents and instruments as may be required to effect
a transfer of Exchangeable Shares under the Act and the bylaws of the Surviving
Corporation and such additional documents and instruments as the Transfer Agent
may reasonably require, the holder of such surrendered certificate or
certificates shall be entitled to receive in exchange therefor, and the Transfer
Agent on behalf of BackWeb Parent shall deliver to such holder, certificates
representing the BackWeb Parent Ordinary Shares to which the holder is entitled
and a cheque or cheques of BackWeb Parent payable at par and in Canadian dollars
at any branch of the bankers of BackWeb Parent or of the Surviving Corporation
in Canada in payment of the remaining portion, if any, of the total Redemption
Call Purchase Price. If BackWeb Parent does not exercise the Redemption Call
Right in the manner described above, on the Redemption Date the holder of the
Exchangeable Shares will be entitled to receive in exchange therefor the
redemption price otherwise payable by the Surviving Corporation in connection
with the redemption of Exchangeable Shares pursuant to Article 7 of the
Exchangeable Share Provisions.

        8.3    Withholding Rights. BackWeb Parent and the Transfer Agent shall
be entitled to deduct and withhold from the consideration otherwise payable to
any holder of Exchangeable Shares such amounts as BackWeb Parent or the Transfer
Agent is required or permitted to deduct and withhold with respect to such
payment under the Income Tax Act (Canada) or any provision of Israeli state,
provincial, local or foreign tax law. To the extent that amounts are so
withheld, such withheld amounts shall be treated for all purposes hereof as
having been paid to the holder of shares in respect of which such deduction and
withholding was made, provided that such withheld amounts are actually remitted
to the appropriate taxing authority. To the extent that the amount so required
or permitted to be deducted or withheld from any payment to a holder exceeds the
cash portion of such consideration as is necessary to provide sufficient funds
to BackWeb Parent or the Transfer Agent, as the case may be, BackWeb Parent is
hereby authorized to sell or otherwise dispose of, or direct to have sold or
disposed of, at fair



                                      -53-
<PAGE>   59

market value, such portion of the Exchangeable Shares or consideration payable
to the holder as is necessary in order to enable BackWeb Parent to comply with
such deduction or withholding requirement and BackWeb Parent or the Transfer
Agent shall give an accounting to the holder with respect thereto and any
balance of such proceeds of sale.

                                   ARTICLE IX

                        TERMINATION, AMENDMENT AND WAIVER

        9.1    Termination. Except as provided in Section 9.2 below, this
Agreement may be terminated and the Amalgamation abandoned at any time prior to
the Closing Time:

               (a)    by mutual consent of Lanacom and BackWeb Parent; or

               (b)    by BackWeb Parent or Lanacom if the Closing has not
occurred by August 31, 1997, other than due to the failure of the party seeking
to terminate this Agreement to perform its obligations under this Agreement
which are required to be performed at or prior to the Closing Time; or

               (c)    by BackWeb Parent or Lanacom if there shall be a final
nonappealable order of a court in effect preventing consummation of the
Amalgamation; or there shall be any action taken, or any statute, rule,
regulation or order enacted, promulgated or issued or deemed applicable to the
Amalgamation by any Governmental Entity which would make the consummation of the
Amalgamation illegal; or

               (d)    by BackWeb Parent or Lanacom if there shall be any action
taken, or any statute, rule, regulation or order enacted, promulgated or issued
or deemed applicable to the Amalgamation by any Governmental Entity, which
would: (i) prohibit BackWeb Parent's or Lanacom's ownership or operation of all
or a material portion of the business of Lanacom or (ii) compel BackWeb Parent
or Lanacom to dispose of or hold separate all or a material portion of the
business or assets of Lanacom or BackWeb Parent as a result of the Amalgamation;
or

               (e)    by BackWeb Parent if it is not in material breach of its
obligations under this Agreement and there has been a material breach of any
representation, warranty, covenant or agreement contained in this Agreement on
the part of Lanacom, provided, that, if such breach is curable by Lanacom within
five (5) business days through the exercise of its reasonable best efforts, then
for so long as Lanacom continues to exercise such reasonable best efforts
BackWeb Parent may not terminate this Agreement under this Section 9.1(e) unless
such breach is not cured within five (5) business days following written
notification of such breach to Lanacom from BackWeb Parent (with the provision
that no cure period shall be required for a breach which by its nature cannot be
cured); or

               (f)    by Lanacom if it is not in breach of its obligations under
this Agreement and there has been a material breach of any representation,
warranty, covenant or agreement contained in this



                                      -54-
<PAGE>   60

Agreement on the part of BackWeb Parent, provided that, if such breach is
curable by BackWeb Parent within five (5) business days through the exercise of
its reasonable best efforts, then for so long as BackWeb Parent continues to
exercise such reasonable best efforts Lanacom may not terminate this Agreement
under this Section 9.1(f) unless such breach is not cured within five (5)
business days following written notice of such breach to BackWeb Parent by
Lanacom (with the provision that no cure period shall be required for a breach
which by its nature cannot be cured).

        Where action is taken to terminate this Agreement pursuant to this
Section 9.1, it shall be sufficient for such action to be authorized by the
Board of Directors (as applicable) of the party taking such action.

        9.2    Effect of Termination. In the event of termination of this
Agreement as provided in Section 9.1, this Agreement shall forthwith become void
and there shall be no liability or obligation on the part of BackWeb Parent or
Lanacom, or their respective officers, directors or shareholders; provided,
however, that each party shall remain liable for any breaches of this Agreement
prior to its termination; and provided further that, Sections 5.2, 5.3, 5.4,
Article IX and Article X of this Agreement shall remain in full force and effect
and survive any termination of this Agreement.

        9.3    Amendment. Except as is otherwise required by applicable law
after the shareholders of Lanacom approve this Agreement, this Agreement may be
amended by the parties hereto at any time by execution of an instrument in
writing signed on behalf of each of the parties hereto.

        9.4    Extension; Waiver. At any time prior to the Closing Time, BackWeb
Parent, on the one hand, and Lanacom, on the other hand, may, to the extent
legally allowed: (i) extend the time for the performance of any of the
obligations of the other party hereto, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto, and (iii) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party.

        10.2   Interpretation. Any reference to dollar amounts in this Agreement
shall be to United States Dollars ("US$"), unless expressly stated otherwise
herein. Amounts expressed in Canadian dollars are preceded by "Cdn$." The words
"include," "includes" and "including" when used herein shall be deemed in each
case to be followed by the words "without limitation." References to "business
day" shall mean any day upon which banks are ordinarily open for business in
both Toronto, Canada and the State of California. The table of contents and
headings contained in this Agreement are for reference purposes only and shall
not affect in any way the meaning or interpretation of this Agreement.

        10.3   Counterparts. This Agreement may be executed in one or more
counterparts (including by means of telecopier), all of which shall be
considered one and the same agreement and shall become effective when one or
more counterparts have been signed by each of the parties and delivered to the
other party, it being understood that all parties need not sign the same
counterpart.

        10.4   Entire Agreement; Assignment. This Agreement, the schedules and
Exhibits hereto, and the documents and instruments and other agreements among
the parties hereto referenced herein: (a) constitute the entire agreement among
the parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof; (b) are not intended to confer upon any
other person any rights or remedies hereunder except that the Agent and the
Escrow Agent shall have the express rights articulated in Article VII hereof;
and (c) shall not be assigned by operation of law or otherwise except as
otherwise specifically provided, except that BackWeb Parent may assign its
rights and delegate its obligations hereunder to its affiliates provided that
BackWeb parent shall continue to be bound thereby.

        10.5   Severability. In the event that any provision of this Agreement
or the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

        10.6   Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such party, and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy.

        10.7   Governing Law; Consent to Jurisdiction. This Agreement shall be
governed by and construed in accordance with the laws of the State of New York,
regardless of the laws that might otherwise govern under applicable principles
of conflicts of laws thereof. Each of the parties hereto irrevocably (i) agrees
that any legal suit, action or proceeding against the other parties to this
Agreement in connection with any matter based upon or arising out of this
Agreement or the matters contemplated herein may be instituted in a federal or
state court within the federal Northern District of California or in any federal
or provincial court in the Province of Ontario, Canada (ii) waives to the
fullest extent it may effectively do so, any objection which it may now or
hereafter have to the laying of venue of any



                                      -58-
<PAGE>   64

such proceeding, and (iii) submits to the non-exclusive jurisdiction of such
courts in any suit, action or proceeding. Lanacom has appointed CT Corporation
System, 818 West 7th Street, Los Angeles, California 90017 as its authorized
agent and BackWeb Parent has appointed BackWeb Technologies Inc., 2077 Gateway
Place, Suite 500, San Jose, California 95110 as its authorized agent (each an
"Authorized Agent") upon whom process may be served in connection with any
action based on this Agreement or any transaction contemplated hereby which may
be instituted in any federal or state court within the federal Northern District
of California and BackWeb Parent has appointed BackWeb Canada as an additional
Authorized Agent upon whom process may be served in connection with any action
based on this Agreement or any transaction contemplated hereby which may be
instituted in any federal or provincial court in the Province of Ontario,
Canada. In each case, such appointment shall be irrevocable. Each of the parties
hereto represents and warrants that the Authorized Agent has agreed to act as
such agent for service of process and agrees to taken any and all action,
including the filing of any and all documents and instruments, that may be
necessary to continue such appointment in full force and effect as aforesaid.
Service of process upon an Authorized Agent and written notice of such service
to the applicable party shall be deemed, in every respect, effective service of
process upon such party.

        10.8   Rules of Construction. The parties hereto agree that they have
been represented by counsel during the negotiation and execution of this
Agreement and, therefore, waive the application of any law, regulation, holding
or rule of construction providing that ambiguities in an agreement or other
document will be construed against the party drafting such agreement or
document.

transaction affecting the shares of Parent Common Stock;

unless (i) the Company is permitted under applicable law to simultaneously make
the same or an economically equivalent change to, or in the rights of holders
of, the Exchangeable Shares and (ii) the same or an economically equivalent
change is made to, or in the rights of the holders of, the Exchangeable Shares.



<PAGE>   102

             (c) The independent auditors selected by Parent (the "Auditors")
shall determine, in good faith, economic equivalence for the purposes of any
event referred to in subsection 2.6(a) or 2.6(b) above and each such
determination shall be conclusive and binding on the Company. In making each
such determination, the following factors shall, without excluding other factors
determined by the Auditors to be relevant, be considered by the Auditors.

                 (i) in the case of any stock dividend or other distribution
payable in shares of Parent Common Stock, the number of such shares issued in
proportion to the number of shares of Parent Common Stock previously
outstanding;

                 (ii) in the case of the issuance or distribution of any rights,
options or warrants to subscribe for or purchase shares of Parent Common Stock
(or securities exchangeable for or convertible into or carrying rights to
acquire shares of Parent Common Stock), the relationship between the exercise
price of each such right, option or warrant and the current market value (as
determined by the Auditors in the manner above contemplated) of a share of
Parent Common Stock;

                 (iii) in the case of the issuance or distribution of any other
form of property (including without limitation any shares or securities of the
Parent of any class other than Parent Common Stock, any rights, options or
warrants other than those referred to in subsection 2.6(c)(ii) above, any
evidences of indebtedness of the Parent or any assets of the Parent), the
relationship between the fair market value (as determined by the Auditors in the
manner above contemplated) of such property to be issued or distributed with
respect to each outstanding share of Parent Common Stock and the current market
value (as determined by the Auditors in the manner above contemplated) of a
share of Parent Common Stock; and

                 (iv) in the case of any subdivision, redivision or change of
the then outstanding shares of Parent Common Stock into a greater number of
shares of Parent Common Stock or the reduction, combination or consolidation or
change of the then outstanding shares of Parent Common Stock into a lesser
number of shares of Parent Common Stock or any amalgamation, merger,
reorganization or other transaction affecting the Parent Common Stock, the
effect thereof upon the then outstanding shares of Parent Common Stock.

         For purposes of the foregoing determinations, the current market value
of any security shall be determined by the Auditors, in good faith, and provided
that any such determination by the Auditors shall be conclusive and binding on
the Company.

         2.7 Tender Offers, Etc. In the event that a tender offer, share
exchange offer, issuer bid, takeover bid or similar transaction with respect to
Parent Common Stock (an "Offer") is proposed by the Parent or is proposed to the
Parent or its shareholders and is recommended by the Board of Directors of the
Parent, or is otherwise effected or to be effected with the consent or approval
of the Board of Directors of the Parent, the Parent will use its best efforts
expeditiously and in good faith to take all such actions and do all such things
as are necessary or desirable to enable and permit holders


<PAGE>   103


of Exchangeable Shares to participate in such Offer to the same extent and on an
economically equivalent basis as the holders of shares of Parent Common Stock,
without discrimination. Without limiting the generality of the foregoing, the
Parent will use its best efforts expeditiously and in good faith to ensure that
holders of Exchangeable Shares may participate in all such Offers without being
required to retract Exchangeable Shares as against the Company (or, if so
required, to ensure that any such retraction shall be effective only upon, and
shall be conditional upon, the closing of the Offer and only to the extent
necessary to tender or deposit to the Offer).

         2.8 Ownership of Outstanding Shares. Without the prior approval of the
Company and the prior approval of the holders of the Exchangeable Shares given
in accordance with the terms of the Exchangeable Share Provisions, the Parent
covenants and agrees in favor of the Company that, as long as any outstanding
Exchangeable Shares are owned by any person or entity other than the Parent or
any of its Affiliates, the Parent will be and remain the direct or indirect
beneficial owner of all issued and outstanding shares in the capital of the
Company and all outstanding securities of the Company carrying or otherwise
entitled to voting rights in any circumstances, in each case other than the
Exchangeable Shares.

         2.9 Due Performance. On and after the Closing Date, the Parent shall
duly and timely perform all of its obligations provided for in the Acquisition
Agreement, including any obligations that may arise upon the exercise of the
Parent's rights under the Exchangeable Share Provisions.

                                    ARTICLE 3

any party other than the Parent and any of its Affiliates.

         3.2 Changes in Capital of Parent and the Company. Notwithstanding the
provisions of section 3.4 hereof, at all times after the occurrence of any event
effected pursuant to section 2.6 or 2.7 hereof, as a result of which either the
Parent Common Stock or the Exchangeable Shares or both are in any way changed,
this agreement shall forthwith be amended and modified as necessary in order
that it shall apply with full force and effect, mutatis mutandis, to all new
securities into which the Parent Common Stock or the Exchangeable Shares or both
are so changed and the parties hereto shall execute and deliver an agreement in
writing giving effect to and evidencing such necessary amendments and
modifications.

         3.3 Severability. If any provision of this agreement is held to be
invalid, illegal or unenforceable, the validity, legality or enforceability of
the remainder of this agreement shall not in any way be affected or impaired

this agreement as may be necessary or desirable with respect to matters or
questions which, in the opinion of the Board of Directors of each of the Company

directors shall be of the opinion that such amendments or modifications will not
be prejudicial to the interests of the holders of the Exchangeable Shares; or

             (c) making such changes or corrections which, on the advice of
counsel to the Company and the Parent, are required for the purpose of curing or
correcting any ambiguity or defect or inconsistent provision or clerical
omission or mistake or manifest error, provided that the boards of directors of
each of the Company and the Parent shall be of the opinion that such changes or
corrections will not be prejudicial to the interests of the holders of the

Shares for the purpose of considering any proposed amendment or modification

         NOW, THEREFORE, the parties agree as follows:

         1. The preamble to this Agreement constitutes an integral part of the
Agreement.

         2. Bring Along Rights.

                  2.1 Subject to the rights set forth in Section 4 hereof, each
Shareholder agrees that, from and after December 9, 1998, in the event that
Shareholders owning at least seventy five percent (75%) of the total number of
shares of capital stock of the Company held by all Shareholders (on a fully
diluted basis) (the "PROPOSING SHAREHOLDERS") shall have approved in writing a
transaction or series of related transactions with any person or persons
regarding a sale of all Shares held by such Proposing Shareholders, such
Proposing Shareholders shall be entitled, at their option, to require each other
Shareholder to include all of its Shares in such transfer by providing each such
other Shareholder with a notice (the "BRING-ALONG NOTICE"), at least thirty (30)
days prior to the consummation of the proposed transaction, setting forth in
reasonable detail the material terms and conditions of the proposed transaction
and the price per share at which such other Shareholders shall be required to
sell their Shares (which price shall be equal to the price at which such
Proposing Shareholders have agreed to sell their shares). (Such entitlement
shall be referred to herein as the "BRING-ALONG RIGHTS".) Upon receipt of
the Bring-Along Notice, each such other Shareholder shall


<PAGE>   110


be obligated to sell all its Shares in connection with such proposed
transaction.

                  (a) At the closing of the proposed transaction (which date,
place and time shall be designated by the Proposing Shareholders and provided to
each other Shareholder in writing at least five (5) business days prior
thereto), each such other Shareholder shall deliver certificates evidencing all
its Shares, duly endorsed, or accompanied by written instruments of transfer in
form satisfactory to the proposed purchaser, duly executed, by such Shareholder,
free and clear of any liens, against delivery of the purchase price therefor.

                  (b) The Bring-Along Rights shall not apply to a disposition by
any Shareholder to (a) any other shareholder of the Company or (b) an affiliate
of the disposing Shareholder (including any family member of a Shareholder or
trust for the benefit of a Shareholder or family members), provided the
transferee agrees in writing to be subject to the terms and conditions of this
Agreement as if it were an original party thereto.

         3. Right of Co-Sale.

                  3.1 Notice of Purchase Offer. Except as provided in section
3.2(e) and subject to the rights and obligations set forth in Section 2 hereof,
in the event that any Founder decides to sell, transfer, or otherwise dispose of
the Founder's Shares (any such event, a "DISPOSITION"), pursuant to a bona fide
offer, then the Founder shall notify each Series B Holder and each Series C
Holder owning at least 800,000 shares of Series B Preferred or Series C
Preferred (and Ordinary Shares issued upon conversion thereof) (subject to
adjustment for all stock splits, dividends, reclassifications and like events)
(each, a "MAJOR HOLDER") of the terms and conditions of such a proposed
Disposition (a "PROPOSED DISPOSITION").

                  3.2 Co-Sale Right.

                           (a) If the Founder proposes to enter into a Proposed
Disposition, then, as a condition to such Proposed Disposition, the Major
Holders shall have the right (a "CO-SALE RIGHT"), to sell their Series B
Preferred and Series C Preferred (and Ordinary Shares issued upon conversion
thereof), as the case may be, to the proposed purchaser in such a transaction on
a pro rata basis (determined as provided below) for the same consideration and
otherwise on the same terms as the Founders.

                           (b) The pro ration of the Co-Sale Right of each Major
Holder shall be calculated in such a manner that each Major Holder shall have
the right to sell in the Proposed Disposition a number of Preferred or Ordinary
Shares, as the case may be, equal to the aggregate number of Preferred or
Ordinary Shares, as the case may be, proposed to be sold multiplied by a
fraction, the numerator of which is the aggregate number of Ordinary Shares
owned by such Major Holder (on a fully-diluted basis, assuming conversion of all
Preferred), and the denominator of which is the sum of the aggregate number of
Ordinary Shares owned by all Founders and all Major Holders (on a fully-diluted
basis, assuming conversion of all Preferred).




<PAGE>   111

                           (c) For purposes of this Section 3.2, to the extent
that Ordinary Shares issuable upon conversion of the Preferred are to be sold
pursuant to the Co-Sale Right, and to the extent any of the Major Holders
decides to exercise its Co-Sale Right, such Major Holder will convert an
appropriate number of shares of its Preferred into Ordinary Shares at such time.

                           (d) A notice of a Proposed Disposition shall be sent
to each of the Major Holders not less than 30 days before the proposed
consummation date of the sale specified in such notice. A Co-Sale Right pursuant
to this Section 3.2 shall be exercisable upon written notice by each of the
Major Holders not less than five business days prior to such specified
consummation date (the "NOTICE PERIOD"). If any of the Major Holders does not
elect during the Notice Period to participate in a particular sale for which
notice has been given pursuant to this Section 3.2(d), then such Major Holder
shall not have any further Co-Sale Right with respect to such Proposed
Disposition and the Founders shall be free to sell, transfer or otherwise
dispose of the shares that such Major Holder was entitled to purchase; provided,
that there has been no material change to any of the material terms of the
Proposed Disposition.

                           (e) The Co-Sale Right shall not apply to a
disposition by the Founders to (i) an affiliate of the Founders (including any
family member of a Founder or trust for the benefit of a Founder or family
members), (ii) any other shareholder of the Company, or (iii) de minimis
dispositions (not exceeding a total of 98,000 shares in any 12 month period by
any Founder, subject to an aggregate limit of 392,000 shares for each Founder),
provided the transferee agrees in writing to be subject to the terms and
conditions of this Agreement as if it were an original party thereto.

         4. Right of First Refusal.

                  The rights of first refusal set forth in Article 19 of the
Company's Articles of Association are incorporated herein by reference.

         5. Board of Directors. Each Shareholder agrees to vote its shares of
capital stock in the Company to give effect, and to cause the Company to give
effect, to the provisions of this Section 5(a).

                  (a)      (i) All of the members of the Board of Directors

                     EMPLOYMENT AND NONCOMPETITION AGREEMENT


         THIS EMPLOYMENT AND NONCOMPETITION AGREEMENT ("Agreement"), dated as of
July 1, 1997, is entered into by and among (i) BackWeb Canada Inc. ("Old BackWeb
Canada"), a corporation incorporated under the laws of Ontario and a
wholly-owned subsidiary of BackWeb Technologies Ltd., an Israeli company
("BackWeb Parent"), and (ii) Anthony Davis, the undersigned executive (the
"Executive").

                                    Recitals

         A. This Agreement is entered into in connection with and is ancillary
to an Agreement and Plan of Acquisition ("Acquisition Agreement") dated as of
July 1, 1997 between BackWeb Parent, Old BackWeb Canada, Lanacom Inc., an
Ontario corporation ("Lanacom") and Executive, which requires, among other
things, that the Executive enter into this Agreement in connection with the
amalgamation ("Amalgamation"), as described in the Acquisition Agreement;

         B. The Executive is an employee of Lanacom. Upon the closing of the
Acquisition Agreement (the "Closing") the Executive shall remain an employee of
the amalgamated company, also called BackWeb Canada Inc. ("BackWeb Canada");

         C. The Executive is a founder and executive of Lanacom and has been
actively involved in the development and marketing of Lanacom's products.
BackWeb Canada intends to continue the business of Lanacom after the Closing. To
preserve and protect the assets of Lanacom, including Lanacom's goodwill,
customers and trade secrets of which the Executive has, and will, in his role as
an employee of BackWeb Canada or its subsidiaries, have knowledge, and to
preserve and protect BackWeb Canada's goodwill and business interests going
forward, and in consideration for Old BackWeb Canada's entering into and
performing under the Acquisition Agreement, the Executive has agreed to enter
into this Agreement; and

         D. The parties hereto believe the limitations as to time, geographical
area and scope of activity contained in this Agreement hereof are reasonably
necessary to, and no greater than that required to, protect the goodwill and
business interests purchased by BackWeb Canada.

         NOW, THEREFORE, IT IS HEREBY AGREED by and between the parties hereto
as follows:

         1. Effectiveness of Agreement; Employment.

            (a) Effectiveness of Agreement. This Agreement shall become
effective as of the


<PAGE>   165


Closing and shall continue in full force and effect until the second anniversary
of the Closing, unless terminated earlier pursuant to Section 3 hereunder. In
the event that the Amalgamation is not consummated, this Agreement shall be null
and void and neither party hereto shall have any claim (existing, accruing or
future) against the other party under or pursuant to this Agreement.

            (b) Duties. Executive shall be employed by BackWeb Canada as its
President and shall also be an executive officer of BackWeb Parent, as Senior
Vice President, Product Management and Research and Development. Executive
agrees to perform such reasonable responsibilities and duties as may be required
of him by BackWeb Canada; provided, however, that the Board of Directors of
BackWeb Canada (the "Board"), including Eli Barkat, Chairman of the Board,
President and Chief Executive Officer of BackWeb Parent ("Chairman"), shall have
the right to revise such responsibilities from time to time as the Board may
deem appropriate. The Executive acknowledges that in the fulfillment of his
duties, he will be required to spend a substantial portion of his time, which
may be as much as half of his time, in the United States, Israel and other
locales necessary for the performance of his duties; provided, however, that
BackWeb Canada will consult with the Executive to accommodate his reasonable
requests regarding his travel schedule. The Executive shall carry out his duties
and responsibilities hereunder in a diligent and competent manner and shall
devote his full business time, attention and energy thereto. The Executive shall
report directly to the Chairman.

            (c) Termination. BackWeb Canada and the Executive acknowledge and
agree that either BackWeb Canada or the Executive shall have the right to
terminate the Executive's employment at any time. If the Executive's employment
terminates for any reason, the Executive shall not be entitled to any payments,
benefits, damages, awards or compensation other than as provided in Section 3 of
this Agreement, or as may otherwise be available in accordance with BackWeb
Canada's established employee plans and policies in place at the time of
termination.

            (d) Charitable and Other Activities. The Executive may (i) serve on
corporate, civic or charitable boards or committees, (ii) deliver lectures,
fulfill speaking engagements or teach at educational institutions, and (iii)
manage personal and immediate family investments, so long as such activities do
not interfere in any way with the Executive's duties and responsibilities
pursuant to this Agreement.

         2. Compensation and Benefits.

            (a) Base Compensation. BackWeb Canada shall pay the Executive as
compensation for his services a base salary at the annualized rate of
Cdn$151,250.00. Such salary shall be subject to applicable tax withholding and
shall be paid periodically in accordance with normal BackWeb Canada payroll. The
annual compensation specified in this Section 2, together with any increases in
such compensation that the Board may, in its sole discretion, grant from time to
time, is referred to in this Agreement as "Base Compensation."

            (b) Bonus. In addition to his Base Compensation, the Executive shall
be entitled


<PAGE>   166


to participate in the BackWeb Canada bonus program. The Executive's annual bonus
shall be up to a maximum of Cdn$72,875.00 and shall be payable based upon
achievement of specified BackWeb Canada and individual objectives, which
objectives shall be determined by agreement between BackWeb Canada and the
Executive, each acting reasonably.

            (c) Options. As of the Closing, the Executive shall be granted an
option ("Option") to purchase an aggregate of up to ______________ BackWeb
Parent Ordinary Shares at an exercise price of US$0.50 per share. The Option
shall be granted to the Executive pursuant to and in accordance with Back Web
Parent's standard terms and conditions, including vesting over four (4) years
(commencing, in the case if the Executive, on July 1, 1996) and such other terms
and conditions as set forth in Back Web Parent's standard option agreement.

            (d) Executive Benefits. The Executive shall be eligible to
participate in (i) the employee benefit plans and arrangements which are
available or which become available, in the discretion of BackWeb Canada's
Board, to other executives and employees of BackWeb Canada and (ii) the employee
benefit plans and arrangements of BackWeb Parent which are available or which
become available, in the discretion of BackWeb Parent's Board, to the executives
and employees of the subsidiaries of BackWeb Parent; subject in each case to the
generally applicable terms and conditions of the plan or program in question and
to the determination of any committee administering such plan or program.
BackWeb Parent shall use commercially reasonable efforts to ensure that
Executive's benefits package as a whole is comparable to the benefits package of
other executive officers of BackWeb Parent.

            (e) Vacation. The Executive shall be entitled to three (3) weeks of
vacation per year in accordance with the normal vacation policies of BackWeb
Canada.

         3. Severance Payments.

            (a) Termination Without Cause. If the Executive's employment
terminates as a result of a termination for any reason other than Cause (as
defined below) or death or disability ("Termination Without Cause"), BackWeb
Canada shall be obligated to pay (i) Base Compensation to the Executive as of
the date of such Termination Without Cause, in an amount equal to three (3)
months of Base Compensation, (ii) a pro-rated amount in respect of his
entitlement to a bonus payment, based on the portion of the relevant bonus
period during which Executive shall be employed and (iii) any accrued and unused
vacation pay to the date of termination of employment, in lieu of any payments
that would be payable to the Executive under applicable Ontario statutory or
common law. The Executive agrees that as a condition to such payments he will
sign a Release of Claims in the form attached as Exhibit A hereto upon receipt
of all amounts contemplated by Section 4 thereof. It is understood by the
parties hereto that a "Termination Without Cause" shall include a material
change or diminution in the Executive's responsibilities at BackWeb Canada or as
a senior executive officer of BackWeb Parent, which change or diminution results
in the Executive's resignation.

            (b) Voluntary Resignation; Termination for Cause. If the Executive's


<PAGE>   167

employment terminates by reason of the Executive's voluntary resignation, or if
the Executive is terminated for Cause, the Executive shall not be entitled to
receive (i) any distributions of the Escrow Fund to which Executive would
otherwise be entitled pursuant to Section 7.2(b) of the Acquisition Agreement or
(ii) severance or other benefits, except any accrued and unused vacation pay and
for those (if any) as may then be established under BackWeb Canada's
then-existing severance and benefits pursuant to this Agreement.

            (c) Death or Disability. If the Executive's employment terminates as
a result of his death or disability, no compensation or payments will be made to
the Executive other than any accrued and unused vacation pay and those to which
he is entitled under BackWeb Canada's existing benefit plans and policies in
place at the time of such termination.

         4. Definitions. As used herein, the term "Cause" means the Executive's
termination only upon:

            (a) The Executive has engaged in wilful and material misconduct,
including, without limitation, wilful and material failure to perform his duties
as an officer or employee of BackWeb Canada or a material breach of this
Agreement and has failed to "cure" such default within thirty (30) days after
receipt of written notice of default from BackWeb Canada;

            (b) The commission of an act of fraud or embezzlement which results
in loss, damage or injury to BackWeb Canada or any of its affiliates or
subsidiaries, including without limitation BackWeb Parent or any of its
Affiliates, whether directly or indirectly;

            (c) The Executive's use of narcotics, liquor or illicit drugs has
had a detrimental effect on the performance of his employment responsibilities,
as determined by BackWeb Canada's Board of Directors;

            (d) The arrest, indictment or filing of charges relating to an
indictable or summary offence, either in connection with the performance of the
Executive's obligations to BackWeb Canada or which shall adversely affect the
Executive's ability to perform such obligations;

            (e) Gross negligence, dishonesty, breach of fiduciary duty or
material breach of the terms of this Agreement or any other agreement in favor
of BackWeb Canada or any of its Affiliates;

            (f) The commission of an act which constitutes unfair competition
with BackWeb Canada or any of its Affiliates, or which induces any customer of
BackWeb Canada or any of its Affiliates to break a contract with BackWeb Canada
or its Affiliates, as applicable.

         5. Confidential Information.

            (a) BackWeb Canada Information. The Executive agrees at all times
during the


<PAGE>   168


term of the Executive's employment and thereafter, to hold in strictest
confidence, and not to use, except for the benefit of BackWeb Canada or its
Affiliates, or to disclose to any person, firm or corporation without written
authorization of the Board or of a senior officer of BackWeb Parent any
Confidential Information of BackWeb Canada or any of its Affiliates. The
Executive understands that "Confidential Information" means any proprietary

of its Affiliates has engaged in licensing or sales or otherwise conducted
business or selling or licensing efforts at any time prior to the Closing hereof
or during the term of this Agreement. The agreement not to compete in each such
geographic subdivision is a separate and severable agreement from all such other
agreements. The Executive acknowledges that the scope and period of restrictions

not entered into any agreements, understandings, or arrangements with any person
or entity which would be breached by the Executive as a result of, or that would
in any way preclude or prohibit the Executive from entering into this Agreement
with BackWeb Canada or performing any of the duties and responsibilities
provided for in this Agreement. The Executive acknowledges that he will resign
as an employee of Lanacom immediately prior to the Closing and shall release
Lanacom from any and all liabilities pertaining to his employment by Lanacom.

         11. Conflicting Employment. The Executive agrees that, during the term
of the Executive's employment with BackWeb Canada, the Executive shall not

12.       THIRD PARTY RIGHTS

12.1      Licensor represents and warrants that it is the owner of the Software
          Products, including all intellectual property rights thereunder,
          copyright, patent, trademark, trade secret and other applicable law,
          and that it has the right to authorize the use of the Software
          Products and the licensing of the Software Products to End-Users by
          SAP and the Applicable Entities.

12.2      Licensor represents and warrants that the execution of this Agreement
          by Licensor does not conflict with any provision of any other
          agreement, court decision or administrative order binding upon it.

12.3      Licensor represents and warrants that the Software Products do not
          infringe any copyright, patent, trademark, trade secret, or other
          intellectual property right of any third party.

12.4      Licensor shall fully indemnify, hold harmless and defend SAP and/or
          the Applicable Entities against suits based on any claim that the
          Software Products infringe any patent, copyright, trademark, trade
          secrets, or other proprietary right, provided that the entity
          concerned gives Licensor prompt written notice of such suits and
          permits Licensor to control the defense and settlement thereof. In the
          event that, as a result of any such claim of infringement, SAP and/or
          the Applicable Entities are enjoined from using, marketing, or
          licensing the Software Products, Licensor shall either procure at its
          expense the right for SAP or the Applicable Entities to continue to
          use, market, and license the Software Products, or replace or modify
          at its expense the Software Products so as to make them
          non-infringing, provided that the performance thereof is not adversely
          affected. Should Licensor fail to do so, Section 9.2 shall apply.
          Irrespective of the aforementioned remedies, Licensor remains liable
          to fully compensate SAP and/or the Applicable Entities concerned for
          any costs and reasonable expenses incurred in connection with such
          third party intellectual property infringement claims up to the amount
          of fees paid by SAP under this Agreement. Damages shall be compensated
          in full. The limitation of liability in Section 14.1 shall not apply.

13.       WARRANTY

13.1      Licensor warrants that the unmodified Software Products will conform
          materially to the specifications and descriptions contained in
          Licensor's then current and applicable documentation.

<PAGE>   13
13.2 The warranty period for all Software Products delivered hereunder shall
     extend for 6 months from the time the respective End User has received the
     Software Product(s) from SAP. In case of any timely notice of defects by
     SAP, the warranty period will be extended for the period of time running
     from the dispatch of the notice of defects until their elimination with
     respect to the affected End Users, if such remedy is elected by SAP.

13.3 With respect to major defects of the master media copies of the Software
     Products which SAP reports to Licensor prior to the expiration of the
     warranty period, Licensor shall either (a) at its expense eliminate the
     defect without undue delay; or (b) at its expense provide SAP with a non
     defective replacement delivery. If Licensor fails to fulfill its
     obligations as stated in (a) and (b) without undue delay and not later than
     two (2) months after being informed of the defect SAP may terminate this
     Agreement in whole or in part.

13.4 Licensor shall pay for all parts, labor, and travel expenses for Licensor's
     service personnel required to fulfill its warranty obligations under this
     Agreement.

13.5 Licensor guarantees, irrespective of fault that the Software Products are,
     and in future releases will be, Year 2000 Compliant. As used in this
     Agreement, "Year 2000 Compliant" shall mean the ability of the Software
     Products to provide the following functions:

     (a)  consistently handle data information before, during, and after January
          1, 2000, including but not limited to accepting date input, providing
          date output, and performing calculations on dates or portions of
          dates;

     (b)  function accurately in accordance with the relevant documentation and
          without interruption before, during, and after January 1, 2000,
          without any change in operations associated with the advent of the new
          century and/or the occurrence of February 29, 2000 (leap day);

     (c)  respond to two-digit year-date input in a way that resolves the
          ambiguity as to century in a disclosed, defined, and predetermined
          manner; and

     (d)  store and provide output of date information in ways that are
          unambiguous as to century.

13.6 In addition to the aforementioned warranty obligations Licensor must
     indemnify and hold harmless SAP from all claims raised by End Users and/or
     the Applicable Entities against SAP for rescission of contract, reduction
     of license fees or damage compensation related to defects of the Software
     Products or the pertinent documentation, but only to the extent that
     liability of SAP for any such claim cannot validly be excluded or limited
     in standard terms and conditions pursuant to mandatory law in the relevant
     jurisdiction.

     This shall not apply to the extent that such defects did not exist at the
     time of receipt of the Software Products by the End User or the Applicable
     Entities or in situations where the
<PAGE>   14
     claims are based on the lack of expressly warranted feature unless the
     subject of such warranty corresponds to a similar warranty given by
     Licensor. The limitation of liability in Section 14.1 shall not apply. SAP
     notifies Licensor of such claims as soon as they come to SAP's knowledge.

14.  LIMITATION OF LIABILITY

14.1 In no event shall either party be liable for any indirect, incidental,
     special or consequential damages, or damages for loss of profits, revenue,
     data or use, incurred by either party, whether in an action in contract or
     tort, even if the other party has been advised of the possibility of such
     damages. The parties liability for direct damages hereunder shall not
     exceed the amount of fees paid by SAP under this Agreement.

14.2 The limitation of liability provided in section 14.1 shall not apply to any
     direct, indirect, incidental, special or consequential damages or damages
     for loss of profits, revenue, data or use arising from any act which, even
     in the absence of this Agreement, would amount to infringement of a
     copyright or patent or misappropriation of a trade secret of the other
     party.

14.3 Either party's liability is not limited in those cases in which:

     It acted with intent or gross negligence.

14.4 Licensor's liability is not limited in those cases in which SAP seeks
     Indemnification under Section 12.4 and 13.6.

                             Common Case Priorities

The End User himself defines the case priority/severity in accordance to the
following general rules.

o    Priority 1; Very high:

     A message with priority "very high" is justified when extremely serious
     interruptions in normal operations occur. Tasks that brook no delay
     whatsoever cannot be executed. This is caused by a complete crash of or by
     interruptions in main functions of the respective software product.

     The message requires immediate processing, as the breakdown can result in
     significant losses.

o    Priority 2; High:

     A message with priority "high" is justified when serious interruptions
     in normal operations occur. Important tasks cannot be performed. This is
     caused by a malfunctioning or unavailable function in the respective
     software product that is urgently required to deal with the current
     situation.

     The message requires quick processing, as a lasting malfunction could
     cause serious interruptions to all work in the production system.

o    Priority 3; Medium:

     A message with priority "medium" is justified when interruptions in normal
     operations occur. This is caused by a malfunctioning or unavailable
     function in the respective software product.

o    Priority 4; Low:

     A message with priority "low" is justified when only minor interruptions in
     normal operations occur. This is caused by a malfunctioning or unavailable
     function in the respective software product that is not required on a
     daily basis or not used regularly.

o    Classification of Test Systems:

                          SUPPORT PROCESS DESCRIPTION

1.   PROCESS DESCRIPTION

1.1  SAP's support organization shall be solely responsible for receiving Cases
     and providing Initial problem evaluation to End Users. Before transferring
     the case to Licensor, SAP will make reasonable efforts to track any case
     down to the level of investigation specified in Exhibit F. If SAP is
     unable to resolve the problem in a timely manner, SAP will initially
     contact the designated technical support department(s), and, if needed,
     the technical support contact(s) of Licensor.

1.2  SAP will supply the technical support department/contact with the required
     End User information specified in Exhibit E. Licensor's technical support
     department/contact will then use reasonable efforts to provide SAP with a
     Case Remedy that is satisfactory to the End User in accordance with the
     applicable priority category of the Common Case Priorities. Licensor agrees
     to provide End Users directly with a Case Remedy when necessary to resolve
     the End User Cases in a prompt manner.

1.3  Each party shall respond to and use reasonable efforts to resolve End User
     Cases in a prompt manner. The solving party will inform the other of the
     final resolution to achieve a Case closure. The decision on whether and
     when a Case is successfully resolved and can therefore be closed is done
     by the End User. Each party acknowledges that, despite a party's
     reasonable efforts, not all problems may be solvable.

2.   ESCALATION OF END-USER PROBLEMS

2.1  The escalation procedure ("escalation") will be followed if either party
     believes a Case requires additional attention by the other party to
     resolve the problem. The escalation process is mainly in progress when a
     technical problem situation arises, however, solution of this problem
     requires non technical support for solving it. Escalation is triggered by
     high levels of End User anxiety when either case occurs:

<PAGE>   35
(a)  A case remedy leads to a not satisfactory End User solution by either party
     involved:

(b)  SAP concerns about the solution given by Licensor (or v.v.);

(c)  the End User who reported the original case is dissatisfied with a given
     solution and comes back to SAP.

2.2  For direct escalation, either party's escalation contact or support
     engineer may call the other party's escalation contact or support engineer
     to start a case escalation. Once a party requests escalation a mutual
     action plan will be developed which defines steps, to resolve End User
     problem. The steps are at minium:

(a)  address resources or increase them if already addressed, and

(b)  define responsibilities for each action, and

(c)  expected completion date and time of each action, and

(d)  contingency/next steps if desired results are not achieved.

2.3  This action plan will be modified by mutual agreement among the designated
     contacts whenever the situation requires.

2.4  When the End User states the problem is resolved or the situation no longer
     requires escalation, the escalation is closed. Each party will exchange
     with the other party the final reports summarizing the actions taken and
     results of these actions, likelihood of problem recurrence and recommended
     future actions.

2.5  A review of the case will be provided for the End User at the End User's
     request or upon the request of SAP.

                             Level of investigation

SAP will provide the initial problem evaluation through SAP Support. The SAP
Support will make a determination of whether a Case is due to a problem with the
integration or the Software Products. If the Case appears to be due to incorrect
installation of the Software Products, due to a defect in the Software Products'
modules of integration, due to use of Software Products, or due to a defect in
Software Products, the SAP Support will refer the Case to Licensor.

If available the SAP Support will include specific identification of the cause
of the problem where possible and providing test cases of same, to the extent
practicable in the circumstances.

               contained in such Baan Technology.

          (b)  To the extent that the Interfaces include any Vendor Technology,
               Vendor shall retain ownership of all Intellectual Property
               Rights contained in such Vendor Technology.

          (c)  Unless otherwise agreed to in a Statement of Work, ownership of
               the Interface shall be as follows: (i) if the Interface is a
               Derivative Work of Vendor Technology, vendor shall own the
               Intellectual Property Rights in the Interface; (ii) if the
               Interface is a Derivative Work of Baan Technology, Baan shall
               own the Intellectual Property Rights in the Interface.

In the event Baan determines in its own judgment that personnel of Vendor
performing development of the Interfaces are not performing in a satisfactory
manner, Baan will notify Vendor within three (3) weeks of the commencement of
services by any such individual. Vendor shall replace the personnel so
identified by Baan at no charge and not charge Baan for those services deemed
non-performing up to a maximum of three (3) weeks of work performed per
engineer.

     2.1.3     Enhancements to Vendor Software. Vendor shall provide Baan with
all Enhancements to the Vendor Software that it makes generally available to
Vendor's supported customers under its support and maintenance agreement in
exchange for the support fees set forth in Exhibit B. In addition, during the
Term, Baan may request that Vendor develop reasonable Enhancements to the
Vendor Software. Vendor shall within thirty (30) days of such request indicate
whether it is willing to perform such development. In the event that Vendor
agrees to perform such development, the terms and conditions of such
development shall be set forth in a Statement of Work executed by the Parties.
Such Statement of Work shall include, without limitation, a Development
Schedule and Specifications. In the event that Vendor does not agree to perform
Enhancements to the Vendor Software requested by Baan within such thirty (30)
day period, Baan shall have, and Vendor hereby irrevocably grants to Baan, the
right to develop or have developed such Enhancements. Notwithstanding anything
to the contrary herein, the Parties agree that Vendor shall have no obligation
to provide any maintenance and support services under Section 3.7 hereof for
any Enhancements to Vendor Software not provided by Vendor.

adjusted as the needs are addressed. The Parties hereby each appoint the
following two individuals as their respective initial members of the Steering
Committee:

     For Baan: John Roberts and Jeff Galea

     2.2  Changes to Specifications. Baan may, by written change order, request
any reasonable changes to, including, but not limited to, additions to or
deletions from Specifications. If any such change results in a material
reduction or increase in the time of performance an appropriate adjustment to
the applicable Development Schedule shall be negotiated by the Parties and the
Joint Development and Release Plan A or the applicable Statement of Work shall
be modified in writing accordingly.

     2.3  Subcontracting. Vendor may subcontract the performance of any portion
of the development to be performed under this Agreement to any third party upon
prior written notice to Baan. Vendor shall provide Baan with the names of any
third parties to whom Vendor subcontracts the performance of any portion of the
development under this Agreement along with proof of receipt of written
assurances regarding protection of Intellectual Property Rights and
confidentiality by such third party contractors. Notwithstanding any such
subcontracting, unless otherwise agreed by the Parties in writing, Vendor shall
in any event and at all times remain liable for performance of this Agreement.

     2.4  Acceptance Procedure. Vendor will notify Baan when it believes it has
completed a Deliverable and will, together with such notification, provide Baan
with such Deliverable in support of its proposed completion. Baan will evaluate
the Deliverable submitted by Vendor as evidence of completion of the same. Baan
agrees that when it has made a finding as to whether Vendor has completed a
Deliverable in accordance with the applicable Specifications, it will promptly
provide a written acceptance or rejection (an "Evaluation") of the Deliverable
to Vendor. Baan shall be deemed to have accepted any Deliverable for which Baan
fails to provide Vendor an Evaluation within sixty (60) days following Baan's
receipt thereof. Any notice of rejection shall set forth in reasonable detail
the basis for Baan's rejection. Upon receipt of a written notice of rejection,
Vendor shall promptly correct the identified deviations from the
Specifications, and each such item shall again be subject to the foregoing
acceptance procedure.

Baan expressly acknowledges that the provisions of this Section are hereby
waived for the items described in Exhibit A.

     2.5  Default in Development. In the event Vendor fails to deliver
Deliverables in accordance with applicable Specifications as required under
Section 2.1 within the time provided in the Development Schedule, or shall have
failed to correct a material deviation from the Specifications within thirty
(30) days after Baan's initial notice thereof under Section 2.4 (or sixty (60)
days if the deviation is non-material), or within such extended period for
performance as may have become applicable pursuant to clause (a) below, then
Baan, at its sole option, and without prejudice to such other legal rights as it
may have hereunder or otherwise, may:

          (a)  extend the time for Vendor' performance; or

          (b)  terminate the applicable Statement of Work and undertake
     completion of the deficient item itself or with the services of any third
     party (subject to adequate protection of Vendor's Intellectual Property
     Rights), with the right to use in connection



                                       6
<PAGE>   7
     therewith any Deliverables previously delivered or due to Baan pursuant to
     this Agreement.

     2.6  No Limitation of Other Rights. Acceptance by Baan of any Deliverable
pursuant to this Section 2 shall not limit in any manner Baan's rights pursuant

Vendor shall deliver to Baan versions of the Vendor Software and the associated
Documentation in the languages specified in Section 2 of Exhibit E in accordance
with the provisions therein. Within a reasonable period after the Effective Date
of this Agreement, Vendor shall provide Baan with a roadmap for translations. If
Baan establishes to Vendor's satisfaction that a profitable market exists for a
given language, Vendor shall translate the Vendor Software for such language at
Vendor's cost. If Baan fails to establish to Vendor's satisfaction that a
profitable market exists for a given language, Vendor shall translate the Vendor
Software for such language at Baan's cost. The projected date of availability
shall be approximately 6 months from the date of such request and shall be no
later than 12 months from the date such request is made to Vendor, unless
otherwise agreed by the parties. In the event that Vendor believes that a
substantial revenue stream has not been established for such translation, Vendor
shall provide written notice to Baan of its intention to discontinue further
translation of the particular affected language. Until Vendor provides Baan with
such notice of its intention to discontinue, Vendor shall provide further
translations in the applicable language for future versions of the Vendor
Software at its expense.

<PAGE>   8
port the Vendor Software for such platform at Vendor's cost. If Baan fails to
establish to Vendor's satisfaction that a profitable market exists for a given
port, Vendor shall port the Vendor Software for such platform at Baan's cost.
The projected date of availability shall be approximately 6 months from the
date of such request and shall be no later than 12 months from the date such
request is made to Vendor, unless otherwise agreed by the parties. In the event
that Vendor believes that a substantial revenue stream has not been established
for such platform, Vendor shall provide written notice to Baan of its intention
to discontinue further porting of the particular affected database platform.
Until Vendor provides Baan with such notice of its intention to discontinue,
Vendor shall provide further ports to the platform for future versions of the
Vendor Software at its expense.

hold Baan harmless from and against all costs, including any interest,
penalties and legal fees, which Baan may incur as a result of such change in
status.

     6.1  Terms of Agreement. The terms of this Agreement are the Confidential
Information of both Parties and shall not be disclosed by either Party in any
manner (including but not limited to news releases, articles, brochures,
advertisements, speeches or other information releases) without the prior
written consent of the other Party not to be unreasonably withheld.

     6.2  Limitations on Use and Disclosure. Each Party receiving Confidential
Information (the "Recipient") agrees as to any such Confidential Information
that may be disclosed to it by the other Party hereunder (the "Discloser"):

          (a)  to protect such Confidential Information from disclosure to
     others, using the same degree of care used to protect its own confidential
     or proprietary information of like importance, but in any case using no
     less than a reasonable degree of care. Recipient may disclose Confidential
     Information received hereunder to (x) its Affiliates who agree, in
     advance, in writing, to be bound by this Agreement, and (y) to its
     employees and subcontractors, and its Affiliates' employees and
     subcontractors, who have a need to know, for the purpose of this
     Agreement, and who are bound to protect the received Confidential
     Information from unauthorized use and disclosure under the terms of a
     written agreement. Confidential Information shall not otherwise be

                                       16




<PAGE>   17
          (c)  not to make copies of any such Confidential Information or any
     part thereof except for the purposes of this Agreement; and

          (d)  to reproduce and maintain on any copies of any Confidential
     Information such proprietary legends or notices as are contained in or on
     the original or as the owner may otherwise reasonably request.

     6.3  Technology. The Parties agree that the Baan Technology or the Vendor
Technology, as applicable, and Deliverables embodying the same, shall be deemed
the Confidential Information of the Party owning such Technology under the terms
hereof.

     6.4  Exceptions. The restrictions of this Section 6 on use and disclosure
of Confidential Information shall not apply to information that (a) was publicly
known at the time of Discloser's communication thereof to Recipient; (b) becomes
publicly known through no fault of Recipient subsequent to the time of
Discloser's communication thereof to Recipient; (c) was in Recipient's
possession free of any obligation of confidence at the time of Discloser's
communication thereof to Recipient; (d) is developed by Recipient independently
of and without reference to any of Discloser's Confidential Information or other
information that Discloser disclosed in confidence to any third party; (e) is
rightfully obtained by Recipient from third parties authorized to make such
disclosure without restriction; or (f) is identified by Discloser as no longer
proprietary or confidential. In addition to the foregoing, it is understood and
agreed that nothing contained in this Section 6 is intended to, nor shall,
restrict the use by either Party of general ideas, concepts, approaches,
techniques or know-how learned or developed by such Party as a result of access
to the Discloser's Confidential Information; provided, however, that such ideas,
concepts, approaches, techniques or know-how are not embodied or specifically
described in written information, software code or other tangible form furnished
by the Discloser to such Party hereunder.

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

     6.6  Return of Confidential Information. All Confidential Information
disclosed under this Agreement (including information in computer software or
held in electronic storage media) shall be and remain the property of
Discloser. All such information in any computer memory or data storage
apparatus shall be erased or destroyed and all such information in tangible form
shall be returned to Discloser, promptly upon the earlier of: (i) the written
request of the Discloser, (ii) completion or termination of the applicable
Statement of Work, or (iii) termination



                                       17

form by Recipient. In the event that Discloser requests the return of
Confidential Information pursuant to subsection (i) above, then Recipient shall
comply with such request; provided, however, that if returning such
Confidential Information prevents Recipient from exercising a license granted
hereunder, such request shall constitute a material breach of this Agreement.
In addition to the foregoing, in the event that either Party has received the
other Party's Source Code in furtherance of the purposes of the Agreement, the
Party receiving such Source Code shall return or destroy all copies thereof as
soon as reasonably practical after no longer having a need for such Source Code.

     6.7  Equitable Relief. The Parties acknowledge that their respective
Confidential Information are unique and valuable, and that breach by either
Party of the obligations of this Agreement regarding such Confidential
Information and intellectual property rights will result in irreparable injury
to the affected Party for which monetary damages alone would not be adequate
remedy. Therefore, the Parties agree that in the event of a breach or
threatened breach of such provisions, the affected Party shall be entitled to
specific performance and injunctive or other equitable relief as a remedy for
any such breach or anticipated breach without the necessity of posting a bond.
Any such relief shall be in addition to and not in lieu of any appropriate
relief in the way of monetary damages.

                                  10. GENERAL

     10.1 Vendor Bankruptcy. If a Bankruptcy Event occurs with respect to
Vendor, Baan shall forthwith be entitled to a complete duplicate of (or
complete access to, as appropriate) any Technology licensed hereunder and all
embodiments of such Technology including the Source Code thereof, and the same,
if not already in Baan's possession, shall be promptly delivered to Baan upon
Baan's written request (i) upon any such Bankruptcy Event, unless Vendor elects
to continue to perform all of its obligations under this Agreement; or (ii) if
not delivered under (i) above, upon rejection of this Agreement by or on behalf
of Vendor. Baan shall have the sublicensable right to fully exploit in any
manner all such Intellectual Property Rights and to perform any and all of
Vendor's obligations hereunder.

In furtherance of the foregoing, upon execution of this Agreement, Vendor
agrees to place into its existing escrow account with Source File, Oakland,
California a copy of the Source Code for the Vendor Software and the related
Documentation, including all updates, Enhancements and new versions
(collectively, the "Source Materials"); provided however that Vendor shall not
be obligated to make deposits into the escrow account more frequently than
twice per year. Baan shall have the right at any time to contact the escrow
agent for the purpose of confirming that the Source Materials in the escrow
account have been updated and verifying the instructions to the escrow agent to
release the Source Materials under the circumstances provided below. Vendor
shall bear all fees, expenses and other charges to maintain such escrow account.

     Vendor's agreement with the escrow agent shall provide that a copy of the
Source Materials will be delivered to Baan by the escrow agent in the event
that: (a) a Bankruptcy Event occurs with respect to Vendor that is not resolved
within sixty (60) days; or (b) Vendor discontinues or is in material breach of
its support obligations for the Vendor Software. In such event, Vendor hereby
grants to Baan a nontransferable, nonexclusive license to use the Source
Materials to support and maintain the Vendor Software, provided however that
such Source Materials may not be used by Baan to create Enhancements to the
Vendor Software. However, Baan shall have the right to use the Source Code to
create Enhancements if the Bankruptcy Event consists of the event specified in
Section 1.5(i) and Vendor has permanently ceased to operate as



                                       20
<PAGE>   21
an ongoing business and if Baan and the successor in interest to Vendor's
rights have mutually agreed in writing to royalties with respect to the
distribution of such Enhancements.

     10.2   Waiver. The failure of either Party to insist on the strict
performance of any terms, covenants and conditions of this Agreement at any
time, or in any one or more instances, or its failure to take advantage of any

                           DEVELOPMENT OF INTERFACES


Baan's Knowledge Manager product is an add-on product to BaanFrontOffice. The
Knowledge Manager, built in conjunction with BackWeb, is comprised of both
client and server components. [*] These pages are being developed by Vendor for
Baan; however, they are calling COM interfaces designed and built by Baan to
retrieve BaanFrontOffice application context. The pages will be integrated into
the BaanFrontOffice navigation system by Baan. There is also an installation
program for the client. The installation program, written by Baan under
Vendor's guidance, call's Vendor's client installer and then installs the
aforementioned pages.

[*]

The final piece of the Knowledge Manager product is Vendor Software that has
been installed at Baan's external Internet Service Provider site. The native
Vendor server is running on Baan's hardware and is configured as the default
home server for all Knowledge Manager clients deployed by Baan. This server
inherits its channel directory from the standard Vendor master server

For the avoidance of doubt, Vendor owns Intellectual Property Rights to all the
Vendor ActiveX controls that are used in the Baan Knowledge Manager product.
Baan owns the Intellectual Property Rights to the web pages that embed the
Vendor ActiveX controls. Baan may use the Vendor ActiveX controls in a new web
page, provided, however, that such use shall be disclosed by Baan at meetings
of the Steering Committee and such use shall be limited to the Baan Knowledge
Manager Product. Vendor is not prohibited in any way to use the controls and
web concepts developed with Baan in future Vendor development initiatives
independent of Baan. Vendor shall be responsible for the maintenance, support
and localization of the Vendor ActiveX controls. Baan agrees to be responsible
for the maintenance, support and localization of the Baan KnowledgeManager web
pages.

the Commission. Confidential treatment has been requested with respect to the

                            MAINTENANCE AND SUPPORT

1.   MAINTENANCE AND SUPPORT OBLIGATIONS OF THE PARTIES

     Baan shall, pursuant to Baan's standard software license and support
agreement ("SLSA"), enter into an agreement with end users for the provision to
end users of maintenance and support for the Vendor Software (as further
described below, "Maintenance and Support"). The Maintenance and Support terms
herein shall also apply to the internal use license of the Vendor Software
granted to Baan under Exhibit C. Maintenance and Support shall consist of Tier
One Support, Tier Two Support and Tier Three Support.

          "Tier One Support" means the provision, during Baan's standard hours
          of service, of assistance via telephone, fax or through Baan's World
          Wide Web Site with respect to the Vendor Software. Such assistance
          shall include: (i) being the first point of contact for all support
          issues relating to Products; (ii) characterizing and analyzing support
          issues; (iii) clarification of functions and features of the Products;
          (iv) clarification of the end user documentation for the Products; (v)
          guidance in the operation of the Products, and (vi) error
          verification, analysis and correction to the extent possible by Baan
          by telephone, fax or through Baan's World Wide Web Site.


          "Tier Two Support" means the support required to resolve any and all
          support issues and problems relating to the Vendor Software that are
          not resolved by Tier One Support.

          "Tier Three Support" means the provisions of corrections for defects
          in the Vendor Software that cause the software to fail to conform to
          the specifications therefore. This shall also include Vendor Software
          Enhancements, new releases, new interfaces as they are generally
          developed and made available.

          As between Baan and Vendor, Baan shall provider Tier One Support to
          end users and Vendor shall provide Tier Two and Tier Three Support to
          Baan; provided however, that in all events, Baan shall use its best
          efforts to provide Tier One, Tier



                                       25
<PAGE>   26
          Two and Tier Three Support to end users; however, in the event Baan is
          unable to address the support request from an end user following its
          best efforts, Vendor shall address such support request directly from
          the end user.

          Vendor shall provide Baan, at no cost to Baan, all necessary
          information, including without limitation one copy of the Vendor
          Software and appropriate Documentation for each of Baan's support
          centers, required by Baan to enable Baan to provide Tier One Support
          for the Vendor Software. Vendor shall once per calendar year provide
          training [*] of Baan's primary support center locations; reasonable
          travel and out-of-pocket expenses for Vendors personnel shall be
          reimbursed by Baan. For all additional locations, Baan will pay Vendor
          for the cost of training services at [*] US/hour and all reasonable
          travel-related expenses. Vendor shall assist Baan in the installation
          of the Vendor Software at such Baan support centers. Baan agrees that
          a minimum of [*] Vendor specialists will be designate who will attend
          the training.

          Vendor shall use its commercially reasonable efforts to resolve all
          reproducible errors in the Vendor Software. Additionally, in the event
          that an error in the Vendor Software either causes a total system
          standstill or causes serious disruption of a major business function,
          Vendor shall use its best efforts to resolve the error and shall work
          diligently until such error is resolved.

          Vendor shall provide the support called for in this Exhibit for the
          then-current release or version of the Vendor Software for a period of
          at least [*] following such release or version's general availability.

2.   PRICING AND PAYMENT

     Each year in which an end user is valid and effective on an annual
     maintenance and support agreement with Baan, Baan shall pay to Vendor [*]
     of the Royalties due to Vendor under Exhibit C for such maintenance and
     support ("Maintenance and Support Fees"). The Parties agree to revisit and
     renegotiate the Maintenance and Support Fees on an annual basis.

     Within thirty (30) days of the end of each month, Baan shall provide to
     Vendor a report setting forth the names of end users from which Maintenance
     and Support Fees were

<PAGE>   27
     received during such month. Baan shall, contemporaneously with the sending
     of such report, wire to a bank and an account named by Vendor the aggregate
     amount of Maintenance and Support Fees due Vendor hereunder for such month.

     Baan shall make and maintain until the expiration of three (3) years after
     the last payment under this Agreement is due, complete books, records and
     accounts regarding its receipt of Maintenance and Support Fees in order to
     calculate and confirm its payment related thereto. Upon reasonable prior
     notice, Vendor shall have the right, exercisable not more than once every
     twelve (12) months, to appoint an independent auditor which auditor shall
     be permitted by Baan to examine such books, records and accounts during
     such Baan's normal business hours to verify reports and payments provided
     pursuant to this Exhibit B. If any such examination discloses a shortfall
     in payment of Royalties, such amounts shall immediately be paid.

     Each Party is responsible for complying with the collection, payment and
     reporting of all taxes imposed by any governmental authority applicable to
     its activities in connection with maintenance and support under this
     Agreement. Neither Party is responsible for the taxes that may be imposed
     on the other Party.

                                   ROYALTIES



1.    Royalties.

(a)   Baan agrees to pay Vendor a royalty advance in the amount of $ [*] USD
(the "Royalty Advance") payable as follows:

the amount of $ [*] USD shall be payable by January 31, 1999 by wire transfer
according to instructions to be provided by Vendor and the remaining $ [*]
shall be payable in four equal quarterly installments in 1999 of $ [*] each on
March 15, July 15, September 15 and December 15, without requirement of
additional invoice, all by wire transfer

(b)   Subject to Sections 2.8 and 2.9, Baan shall pay to Vendor royalties
("Royalties") equal to [*] of Net Sales of the Vendor Software by Baan,
subject to a minimum royalty of $ [*] US per seat for end user transactions of
 [*] seats or less and a minimum royalty of $ [*] US per seat for end user
transactions of [*] seats or more. These minimum royalties are paid based on an
assumed list price of $ [*] for Vendor Software. If market conditions require
that the list price for Vendor Software be decreased, the minimum royalty
amounts shall be decreased on an equal percentage basis upon Vendor's prior
written consent, such consent to not be unreasonably withheld. The parties may
mutually agree in writing to different minimum pricing or percentage royalty
rates on a case by case basis and in addition the Steering Committee shall
address issues of proposed pricing adjustments, including the per seat minimums
to the extent market conditions justify. For purposes of this Exhibit C, "Net
Sales" means the gross revenue due and payable to Baan from the sale or license
of the Vendor Software, less the following items but only insofar as they are
included in such gross revenue and are separately stated on the invoice: (i)
import, export, value added, excise and sales taxes, tariffs, and custom
duties; (ii) credit for returns, damaged goods, allowances, or trades; (iii)
charges for packaging, shipping and insurance; and (iv) customary rebates, cash
and trade discounts, actually taken. Baan will provide Vendor with thirty (30)
days advance notice of its intention to change the list price of the Vendor
Software. For the purposes of Royalty calculations under this Agreement, Baan's
discount to the end user will be evenly allocated across all of the products in
a particular order.

2.    Reports and Payment of Royalties. Within thirty (30) days after the end
of each month Baan shall report to Vendor (i) the names of end users licensing
the Vendor Software, (ii) the number of Users at each end user; (iii) the Net
Sales derived from the end user during such month and (iv) the aggregate
Royalties, including the calculation thereof, owing thereon. Baan shall,
contemporaneously with the sending of such report, wire to Vendor's account as
described in this Exhibit C the Royalties due Vendor, provided that Baan shall
not be required to pay to or

                                       29
<PAGE>   30
otherwise transfer to Vendor any Royalties until it has recouped the royalty
advance described in Section 1(a) of this Exhibit C. All amounts due Vendor
upon recoupment of the Royalty Advance by Baan shall be payable within thirty
(30) days of the last day of the applicable month.

3.    Audit Rights. Baan shall make and maintain until the expiration of three
(3) years after the last payment under this Agreement is due, complete books,
records and accounts regarding its distribution activities of the relevant
products in order to calculate and confirm its Royalty obligations hereunder.
Upon reasonable prior notice, Vendor shall have the right, exercisable not more
than once every twelve (12) months, to appoint an independent auditor which
auditor shall be permitted by Baan to examine such books, records and accounts
during such Baan's normal business hours to verify reports and payments
provided pursuant to Section 4.5 hereof. If any such examination discloses a
shortfall in payment of Royalties, such amounts shall immediately be paid.

4.    Taxes. Royalties are exclusive of sales and/or use taxes that are imposed
on a purchaser of goods and services by law, which Baan agrees are its
responsibility. In the alternative, Baan shall provide Vendor with a
certificate evidencing Baan's exemption from payment of or liability for such
taxes and Vendor agrees to honor such exemption certificate.

5.    Vendor Services. Baan shall pay Vendor for development services rendered
by Vendor engineers pursuant to Section 2.1.1 above at the rate of $ [*]
US/hour. Baan shall pay Vendor for professional services rendered in connection
with training Baan staff at the rate of $ [*] US/hour.

6.    Internal Use Licenses. In further consideration of executing this
Agreement, Baan shall have the right to use the Baan Knowledge Manager, which
includes the Vendor Software, at [*] for use by Baan Sales and Baan
Professional Services organization for use for its own internal data processing
operations. The parties anticipate that the total number of Named Users for
such license shall be approximately [*]. Baan shall have the right to acquire
initial year technical support services for such Named Users at a technical
support services fee of $ [*]/Named User. Vendor agrees that annual increases
for technical support for the licenses granted under this Section 6 shall not
increase by more than [*] per year during the term of this Agreement.

        personnel and its equipment during Service Hours. This access includes
        the ability to dial-in to the equipment on which the Software is
        operating and may also include the ability to obtain the same access to
        the equipment as those of Customer's employees having the highest
        privilege or clearance level. Baan shall at all times be bound by the
        Confidentiality provisions of the Agreement, and will only disclose
        information within Baan to those individuals who need to know in order
        to assist in solving Customer's problem. Baan will inform via the Baan

        in Schedule A. The Support fee for the first Support Term is due and
        payable in full in advance within thirty (30) days after the Effective
        Date. For any subsequent Support Term, the Support fee will be due and
        payable thirty (30) days before the commencement of such subsequent
        Support Term. Any amounts not paid within thirty (30) days will be
        subject to interest of one percent (1%) per month, which interest will
        be immediately due and payable.

2.9     Modified Support Fee. Baan may modify the Support fee for any Support
        Term. However, for a period of four (4) years from the Effective Date
        the Support fee for Current Programs for each subsequent Support Term
        shall not be more than five percent (5%) plus the Consumer Price Index
        for the applicable time period. In the event of a modification of the
        Support fee, Customer may discontinue Support.

2.10    Incentive Program. Where a Customer has become more competent in using
        the Software and in providing internal support to its organization, the
        Support fee payable by Customer for a subsequent Support Term shall be
        discounted by twenty five percent (25%) provided that all of the
        following conditions are satisfied:

(a)     the total number of Knowledge Related Support Calls made by Customer
        during the immediately preceding Support Term is no more than twenty
        percent (20%) with respect of the total of Quality Related Support Calls
        received during such Support Term. For the purposes of this Section,
        Baan's determination of whether a Support Call relates to knowledge or
        quality is final and conclusive and may not be challenged in any way by
        Customer other than during the first thirty (30) days after Baan updates
        Customer with the nature of the Support Calls received from Customer.

(b)     Customer has paid the standard support fee;

        Customer intends to avail itself of the provisions of this Section; and
        Customer is using Current Programs.
