PROSPECTUS

                           THE LEARNING COMPANY, INC.


                        4,438,480 SHARES OF COMMON STOCK

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

   
     Each of the 4,438,480 shares (the "Shares") of common stock, par value
$0.01 per share (the "Common Stock"), of The Learning Company Inc., a Delaware
corporation (the "Company"), offered hereby is issuable upon exchange or
redemption of certain exchangeable non-voting shares (the "New Exchangeable
Shares") of SoftKey Software Products Inc., an Ontario corporation ("SoftKey").
SoftKey, the issuer of the New Exchangeable Shares, is a subsidiary of the
Company. The New Exchangeable Shares are issuable upon exercise of special
warrants (the "Warrants") to purchase non-voting exchangeable shares of SoftKey
offered and sold outside the United States pursuant to the requirements of
Regulation S under the Securities Act of 1933, as amended (the "Securities
Act"). This Prospectus does not cover the exchange of the New Exchangeable 
Shares by the initial purchasers of the Warrants. The Warrants will be 
exercisable upon the later of (i) approval by the holders of the outstanding 
exchangeable non-voting shares of SoftKey of the issuance of New Exchangeable 
Shares, and (ii) the date that all other consents and approvals necessary to 
ensure that the rights and benefits of the holders of the New Exchangeable 
Shares are substantially equivalent to the rights and benefits of the holders 
of the outstanding exchangeable non-voting shares of SoftKey (the exchangeable
non-voting shares of SoftKey, including the New Exchangeable Shares, are
collectively referred to herein as the "Exchangeable Shares"), provided that if
the conditions specified in (i) and (ii) are not met by March 6, 1998, the
Warrants will be redeemed by SoftKey. See "Plan of Distribution." The Company
has outstanding a single share of special voting stock, $1.00 par value per
share (the "Voting Share"), which has a number of votes equal to the number of
Exchangeable Shares outstanding from time to time not owned by the Company, or
an entity controlled by or under common control with the Company, for the
election of directors and on all other matters submitted to a vote of
stockholders of the Company. The holder of the Voting Share is not entitled to
dividends and shall vote with the holders of Common Stock of the Company as a
single class. The Exchangeable Shares may be exchanged for the Company's Common
Stock on a one-for-one basis until February 4, 2005, at which time any
outstanding Exchangeable Shares will be purchased or automatically redeemed for
shares of the Common Stock of the Company. Shares of Common Stock are being
offered on a continuous basis pursuant to Rule 415 under the Securities Act for
such period as the Registration Statement to which this Prospectus relates
remains effective.
    

     The Company and SoftKey are offering shares of Common Stock to holders of
New Exchangeable Shares pursuant to the terms of the Exchangeable Shares, which
obligate the Company and SoftKey to effect such exchanges when, as and if
Exchangeable Shares are presented by the holders thereof for exchange. Upon such
exchange, holders of Exchangeable Shares will be entitled to receive for each
Exchangeable Share one share of Common Stock, plus an additional amount
equivalent to the full amount of all declared and unpaid dividends on such
Exchangeable Share. See 


                                      -3-

"Plan of Distribution." All expenses of registration incurred in connection with
this offering are being paid by the Company.

   
     The Company's Common Stock is traded on the New York Stock Exchange (the
"NYSE") under the symbol "TLC." On December 1, 1997, the closing sale price of
the Common Stock on the NYSE was $18.5625 per share.

                                   THE COMPANY

     The Learning Company, Inc. (the "Company") develops and publishes a broad
range of high quality consumer software for personal computers ("PCs") that
educate across every age category, from young children to adults. The Company's
primary emphasis is in education and reference software, but it also offers a
selection of lifestyle, productivity and, to a lesser extent, entertainment
products, both in North America and internationally.

     The Company's families of educational products are principally sold under
The Learning Company and Minnesota Educational Computing Corporation ("MECC")
brands and include the "Reader Rabbit" family, "Trail" family, "Writing and
Creativity Tools" family, "College Prep" family, and the "Foreign Languages"
family. In addition to consumer versions, the Company also publishes school
editions of a number of these products. The Company's reference products include
a line of Compton's Home Library branded products (including Compton's
Interactive Encyclopedia) as well as the American Heritage Talking Dictionary,
Mosby's Medical Encyclopedia and BodyWorks. The Company's premium productivity
and lifestyle products are largely published under the SoftKey brand. The
Company also publishes lower priced boxed products under the "Key" brand and a
line of budget, jewel-case only products under the "Platinum" brand.

     The Company distributes its products through retail channels, including
direct sales to computer electronics stores, office superstores, mass
merchandisers, discount warehouse stores and software specialty stores which
control over 23,000 North American storefronts. The Company also sells its
products directly to consumers through the mail, telemarketing and the Internet,
and directly to schools. The Company's international sales are conducted from
subsidiaries in Germany, France, Holland, Ireland, the United Kingdom, Australia
and Japan. The Company also derives revenue from licensing its products to
original equipment manufacturers ("OEMs") which bundle the Company's products
for sale with computer systems or components and through on-line offerings.

     The Company's strategy is to develop and publish a broad range of high
quality software products with significant unit-volume potential and to
continuously introduce these new products through a wide variety of established
and emerging distribution channels worldwide. Other key elements of this
strategy include focusing on consumer software that is broadly sold at multiple
price points, building strong relationships with the retail channel, acquiring
complementary products, technologies and businesses and enhancing brand
awareness and customer loyalty.

     The Company has a history of acquiring companies in order to broaden its
product lines and sales channels. In May 1996, the Company consummated the
acquisition of MECC. That acquisition, together with the acquisitions in
December 1995 of The Learning Company and Compton's NewMedia, Inc. ("Compton's
NewMedia"), marked the completion of a strategic initiative launched by the
Company in 1995 to expand its educational software franchise.

     The Company was incorporated in California in October 1978 and
reincorporated in Delaware in October 1986. In February 1994, the Company, which
was then known as WordStar International Incorporated, completed a three-way
business combination with SoftKey Software Products Inc. and Spinnaker Software
Corporation in which the Company changed its name to SoftKey International Inc.
In October 1996, the Company changed its name to The Learning Company, Inc. to
reflect its expanded emphasis on educational software. The Company's executive
offices are located at One Athenaeum Street, Cambridge, Massachusetts 02142. Its
telephone number is (617) 494-1200, and its internet web site is located at
http:/www.learningco.com. "The Learning Company, Inc." and all of the Company's
logos and product names are trademarks of the Company.

                                  RISK FACTORS

     The Shares offered hereby involve a high degree of risk. The following risk
factors should be considered carefully in addition to the other information
included or incorporated by reference in this Prospectus.


TAXABILITY OF THE EXCHANGE

     Based on the tax laws as of the date of this Prospectus, the exchange of
Exchangeable Shares for Shares is generally a taxable event in Canada and the
United States. A holder's tax consequences can vary depending on a number of
factors, including the residency of the holder and the method of the exchange
(redemption or exchange) (see "Income Tax Considerations").

DIFFERENCES IN CANADA AND U.S. TRADING MARKETS

     The outstanding Exchangeable Shares of SoftKey are listed on The Toronto
Stock Exchange (the "TSE") and the Common Stock is listed on the NYSE. The TSE
has conditionally approved the listing of the New Exchangeable Shares. There is
no current intention to list the Exchangeable Shares or Common Stock on any
other stock exchange in Canada or the United States. As a result of the
foregoing, the price at which the Exchangeable Shares will trade will be based
upon the market for such shares on the TSE and the price at which the shares of
Common Stock will trade will be based upon the market for such shares on the
NYSE. Although the Company believes that the market price of the Exchangeable
Shares on the TSE and the market price of the Common Stock on the NYSE will
reflect essentially equivalent values, there can be no assurances that the
market price of the Common Stock will be identical, or even similar, to the
market price of the Exchangeable Shares.

INTENSE COMPETITIVE ENVIRONMENT

     The PC consumer software industry is intensely competitive and is
characterized by rapid changes in technology and customer requirements. The
changing nature of the consumer software industry and rapidly changing demand
for products make it difficult to predict the future success of the Company in
the business of producing packaged software products for the retail market. The
Company competes for retail shelf space and general consumer awareness with a
number of companies that market software products. The Company encounters
competition from both established companies, including the largest companies in
the industry, and new companies that may develop comparable products. A number
of the Company's competitors and potential competitors possess significantly
greater capital, marketing resources and brand recognition than the Company.
Rapid changes in technology, product obsolescence and advances in computer
software and hardware require the Company to develop or acquire new products and
to enhance its existing products on a timely basis. The Company's marketplace
has recently experienced a higher emphasis on on-line and Internet related
services and content tailored for this new delivery vehicle. To the extent that
demand increases for on-line products and content, the demand for the Company's
existing products and future performance may change. Furthermore, competitive
pressures have resulted in price reductions throughout the industry with the
result that industry-wide operating margins are likely to be adversely affected.

     Many large companies with sophisticated product marketing and technical
abilities and financial resources that do not presently compete with the Company
may enter the PC software market. For example, technology companies have begun
to acquire greater access to content, and content-oriented companies have begun
to acquire greater technological capabilities. Competitors in 


                                      -8-
<PAGE>   9

these areas include CUC Software, a division of CUC International Inc.,
Microsoft Corporation, Mattel, Sony, The Walt Disney Company, Viacom,
IBM/Eduquest, Fisher-Price, Jostens, Electronic Arts, Mindscape, GT Interactive
Software and Broderbund Software, Inc. To the extent that competitors achieve a
performance, price or distribution advantage, the Company could be adversely
affected. Increased consolidation in the consumer software industry creates new,
larger competitors and may impact future growth potential and performance.

     There is no assurance that the Company will have the resources required to
respond to market or technological changes or to compete successfully in the
future.

INTENSE COMPETITION FOR DISTRIBUTION CHANNELS

     The Company competes with other companies for access to retail shelf space
and inclusion in OEM sales programs. Competition in this aspect of the industry
is intense, and the type and number of distribution channels is increasing to
include non-traditional software retailers such as book, music, video, magazine,
toy, gift, convenience, drug and grocery store chains. Additionally, as
technology changes, the type and number of distribution channels will further
change and new types of competitors, such as cable or telephone companies, are
likely to emerge.

     The traditional channels of distribution in the software industry have
experienced increasing concentration during the past several years, in
particular with respect to PC chain stores and software distributors. With
increasing concentration in the traditional channels of distribution, the
Company's customers have increased leverage in negotiating favorable terms of
sale, including price discounts and product return policies. There can be no
assurance that the Company will be able to continue to have access to sufficient
retail marketing distribution channels or obtain adequate distribution for all
of its products in the future. Accordingly, such concentration may have an
adverse effect in the future on the profitability of the Company's operations.

     Regardless of the retail strategy chosen by the Company, the retail
channels of distribution available for products are expected to be subject to
rapid changes as retailers and distributors enter and exit the software market
segments or alter their product inventory preferences. Other types of retail
outlets and methods of product distribution may become important in the future.
These new methods may include delivery of software using on-line services or the
Internet, which will necessitate certain changes in the Company's business and
operations, including without limitation addressing operational challenges such
as improving download time for pictures, images and programs, ensuring proper
regulation of content quality and developing sophisticated security for
transmitting payments. Should on-line distribution channels increase, the
Company will be required to modify its existing technology bases in order for
its products to be compatible and remain competitive. It is critical to the
success of the Company that, as these changes occur, it maintain access to those
channels of distribution offering software in its market segments.

ACQUISITIONS, BUSINESS COMBINATIONS AND STRATEGIC ALLIANCES

     The Company has historically expanded its business through, among other
strategies, acquisitions, business combinations and strategic alliances.
Moreover, the consumer software industry as a whole has recently experienced
consolidation. The Company believes that its customers will in the future demand
that the Company offer increasing numbers of titles throughout the range of
product categories. The Company believes that in many cases the most efficient
means to acquire such titles or the ability to develop or license such titles is
to enter into acquisitions, business combinations or strategic alliances with
consumer software companies and others.




                                      -9-
<PAGE>   10

     The Company continuously evaluates and considers other businesses of
varying sizes as potential strategic partners and candidates for acquisition
(whether negotiated or non-negotiated) and continuously engages in discussions
with certain businesses in pursuit of possible transactions. Certain of these
businesses may be substantial in size as compared to the Company. There can be
no assurance that the Company will enter into any such transaction or, if the
Company does identify and consummate such a transaction, that the transaction
will enable the Company to achieve its goals.

     Acquisitions or business combination transactions that would result in
further expansion of the Company's business in the entertainment and educational
product areas may result in a higher degree of product acceptance risk and
longer development cycles for the Company's products. In addition, companies
that develop entertainment software (for PC, Sega, Nintendo and 3DO platforms)
typically experience lower gross margins than the Company has experienced from
its current operations. Further, should purchase accounting be used by the
Company for future acquisitions or business combination transactions, such
accounting treatment may result in large, one-time expense charges for
in-process research and development costs and short amortization periods for
acquired technology and other intangible assets acquired in the transaction.

     Competition for suitable acquisitions, business combinations and strategic
alliances and the cost of these transactions have recently been increasing. The
future availability of desirable prospects for these transactions in the
computer software industry is uncertain. In addition, assuming that the Company
is able to identify appropriate transaction prospects, the execution and
implementation of acquisitions, business combinations and strategic alliances
involves a significant time commitment from senior management and can result in
large restructuring costs. There can be no assurance that suitable opportunities
will be identified, that transactions can be consummated or that assets,
businesses or relationships acquired in such transactions can be integrated
successfully into the Company's operations.

LEVERAGE

     As of November 15, 1997, the Company has outstanding $303,650,000 principal
amount of 5 1/2% Senior Convertible Notes due 2000 (the "Senior Convertible
Notes") and $150,000,000 principal amount of Convertible/Exchangeable notes due
2000 held by Tribune Company (the "Tribune Notes"; collectively with the Senior
Notes, the "Notes"). The Company has entered into an agreement to purchase for
750,000 shares of Series A Convertible Participating Preferred Stock, $.01 par
value per share, of the Company (the "Preferred Stock"), the Tribune Notes from
certain purchasers who have agreed to purchase the Tribune Notes from Tribune
Company. The repurchase of the Tribune Notes is subject to certain conditions,
including approval of the Company's stockholders of the sale and issuance of the
Preferred Stock, and there can be no assurance that such transaction will be
completed. The Senior Convertible Notes and, if they are not repurchased, the
Tribune Notes will be redeemable by the Company on or after November 2, 1998 at
declining redemption prices. If the holders of the Senior Convertible Notes and,
if not repurchased, the Tribune Notes do not convert the Notes held by them into
Common Stock, there can be no assurance that the Company's operating cash flow
will be sufficient to meet its debt service requirements, or that the Company
will be able to repay the Notes at maturity or in accordance with their
respective terms or to refinance the Notes on favorable terms or at all.

MANAGEMENT OF GROWTH; INTEGRATION OF ACQUIRED BUSINESSES; KEY EMPLOYEES

     The Company is currently experiencing a period of rapid growth that is
placing and will likely continue to place a strain on the Company's financial,
management and other resources in the future. The Company's ability to continue
to manage its growth effectively will require it, among other things, to
continue to improve its operational, financial and management information
systems and to continue to attract, train, motivate, manage and retain key
employees. If the Company's management becomes unable to manage growth
effectively, the Company's business, operating results and financial condition
could be adversely affected. For example, over the past two years, the Company
has acquired The Learning Company, Compton's NewMedia, Compton's Learning
Company, MECC, Learning Services, Inc., Skills Bank Corporation and Microsystems
Software, Inc., among other companies, and has signed an agreement to acquire
Creative Wonders LLC. Should certain key employees not be retained, future
operating results may be adversely affected.

     Additionally, as a result of such acquisitions, the Company faces
challenges relating to integration of operations such as coordinating
geographically separate organizations, integrating personnel with disparate
business backgrounds and combining different corporate cultures. The process of
combining organizations may cause an interruption of, or a loss of momentum in,
the activities of the Company's business, which could have an adverse effect on
the revenues and operating results of the Company, at least in the near term.

     The ability of software companies with significant internal development and
marketing capabilities to continue to manage growth, develop competitive new
products and respond to rapid technological change depends on an ability to
attract, motivate, manage and retain talented developers, product marketers and
other employees with valuable technological and marketing expertise. The


                                      -10-
<PAGE>   11

Company's educational software products require a substantially larger internal
development and marketing staff than its operations had previously required. If
the Company is unable to attract, motivate, manage and retain such employees,
the Company's results of operations will likely be adversely affected.

NEW PRODUCTS AND RAPID TECHNOLOGICAL CHANGE

     The Company operates in a highly competitive and technology driven
environment. The consumer software industry is undergoing substantial change and
is subject to a high level of uncertainty. Software companies must continue to
develop or acquire new products or upgrade existing products on a timely basis
to sustain revenues and profitable operations. Factors contributing to the short
life span of PC software have included rapid technological change and an
expanded demand for content-rich products. Software companies must continue to
create or acquire innovative new products reflecting technological changes in
hardware and software and translate current products into newly accepted
hardware and software formats, in order to gain and maintain a viable market for
their products. PC hardware, in particular, is steadily advancing in power and
function, expanding the market for increasingly complex and flexible software
products. This has also resulted in longer periods necessary for research and
development of new products and a greater degree of unpredictability in the time
necessary to develop products. Furthermore, the rapid changes in the market and
the increasing number of new products available to consumers have increased the
degree of consumer acceptance risk with respect to any specific title that the
Company may publish. It is expected that this trend will continue and may become
more pronounced in the future.

     The Company's rights to license certain of its software products are
non-exclusive and, generally, of limited duration, and there is no assurance the
Company will be able to continue to obtain new products from developers or to
maintain or expand its market share in the event that a competitor offers the
same or similar software products. If the Company is unable to develop or
acquire new products in a timely manner as revenues decrease from products
reaching the end of their natural life cycle, the Company's results of
operations will be adversely affected.

COMPETITION FOR SHELF SPACE AND PROMOTIONAL SUPPORT

     Retailers of the Company's products typically have a limited amount of
shelf space and promotional resources, and there is intense competition among
high-quality educational software products for adequate levels of shelf space
and promotional support from retailers. To the extent that the number of
consumer software products and computer platforms increases, this competition
for shelf space may intensify. Due to increased competition for limited shelf
space, retailers and distributors are increasingly in a better position to
negotiate favorable terms of sale, including price discounts and product return
policies, as well as cooperative market development funds. Retailers often
require software publishers to pay fees in exchange for preferred shelf space.
The amounts paid to retailers by software publishers for preferred shelf space
are customarily determined by arms-length negotiations on a case by case basis,
and there is no general formula or industry standard for determining such fees.
There can be no assurance that such retailers will continue to purchase the
Company's products, provide the Company's products with adequate levels and
quality of shelf space or continue to participate with the Company in
cooperative advertising, promotional or market development arrangements. In
addition, the Company has implemented new promotional programs, including coupon
rebates and other various programs through print and television media. These
programs may increase the Company's cost of marketing and reduce operating
margins.



                                      -11-
<PAGE>   12

SIGNIFICANT PRICE REDUCTIONS IN PERSONAL COMPUTER SOFTWARE

     Recently, several major publishers of PC software, including the Company,
have significantly reduced the prices of their products with the goal of gaining
greater market share. The retail and wholesale prices of many of the Company's
products have declined and the Company has introduced new lines of lower-priced
software products. There can be no assurance that such price reductions or new
product lines will result in an increase in unit sales volume or that prices
will not continue to decline in the future. Such a decline would lead to a
decrease in the revenues from, and gross margin on, sales of such products in
the future and could result in lower cash flow or operating margins.

RISK OF INTERNATIONAL OPERATIONS

     The Company derived approximately 15% of its revenues in the year ended
January 4, 1997 from sales occurring outside North America. These revenues are
subject to the risks normally associated with international operations,
including currency conversion risks, limitations (including taxes) on the
repatriation of earnings, slower and more difficult accounts receivable
collection, greater difficulty and expense in administering business abroad,
complications in complying with foreign laws and the necessity of obtaining
requisite export licenses, which on occasion may be delayed or difficult to
obtain. In addition, while U.S. copyright law, international conventions and
international treaties may provide meaningful protection against unauthorized
duplication of software, the laws of foreign jurisdictions may not protect the
Company's proprietary rights to the same extent as the laws of the United
States. Software piracy has been, and can be expected to be, a persistent
problem for participants in the "shrink-wrap" software industry, including the
Company. These problems are particularly acute in certain international markets
such as South America, the Middle East, the Pacific Rim and the Far East.

PROTECTION OF PROPRIETARY RIGHTS; RISK OF INFRINGEMENT CLAIMS

     The Company relies on a combination of trade secret, copyright, trademark
and other proprietary rights laws and license agreements to protect its rights
to its software products and related documentation. The Company does not have
any patents. United States copyright law, international conventions and
international treaties, however, may not provide meaningful protection against
unauthorized duplication of the Company's software. The Company generally
licenses its externally developed products rather than transferring title and
has relied on contractual arrangements with recipients and users of its products
to establish certain proprietary rights and to maintain confidentiality of those
products protected by trade secret law. Consistent with standard industry
practice, the Company's products generally are licensed pursuant to
"shrink-wrap" licenses that are not signed by the licensee. The enforceability
of such licenses has not been conclusively determined. The Company's products do
not contain any mechanisms to prevent or inhibit unauthorized copying.

     The Company has registered numerous trademarks in the United States and
Canada, and a smaller number in other countries, for titles or components of its
products and has trademark registrations pending in the United States and other
countries for various new products.

     Policing unauthorized use of a broadly disseminated product such as PC
software is very difficult. Software piracy can be expected to be a persistent
problem for the "shrink-wrap" software industry. These problems are particularly
acute in certain international markets such as South America, the Middle East,
the Pacific Rim and the Far East.

     The Company periodically receives communications alleging or suggesting
that its products may incorporate material covered by the copyrights, trademarks
or other proprietary rights of third parties. With the increased use of music
and animation in CD-ROM products and the increased 


                                      -12-
<PAGE>   13

number of software products on the market generally, the Company is likely to
experience an increase in the number of infringement claims asserted against it
in the future. With respect to licensed products, the Company is generally
indemnified against liability on these matters. The Company's policy is to
investigate the factual basis of such communications and to resolve such matters
promptly by enforcing its rights, negotiating licenses (if necessary) or taking
other appropriate actions.

     In certain circumstances, litigation may be necessary to enforce the
Company's proprietary rights, to protect copyrights, trademarks and trade
secrets and other intellectual property rights owned by the Company or its
licensors, to defend the Company against claimed infringements of the rights of
others and to determine the scope and validity of the proprietary rights of the
Company and others. Any such litigation, whether with or without merit, could be
costly and a diversion of management's attention, which could have an adverse
effect on the Company's business, operating results or financial condition.
Adverse determinations in litigation relating to any of the Company's products
could result in the loss of the Company's proprietary rights, subject the
Company to liabilities, require the Company to seek licenses from third parties
or prevent the Company from selling that product.

DEPENDENCE ON MAJOR SUPPLIER

     All duplication, assembly and fulfillment, with certain exceptions
(including CD-ROMs and products reproduced by OEMs), for all of the Company's
U.S. products are provided by one supplier, Bertelsmann AG ("BMG"). Any
interruption in BMG's manufacturing, assembly and fulfillment services caused by
such transition or otherwise could have a material adverse impact on the
Company's business. Although the Company believes that suitable alternative
suppliers exist, there can be no assurance that any termination or modification
of the agreement with BMG would not result in a short-term business interruption
for the Company.

HISTORY OF OPERATING LOSSES

     A variety of factors may cause period-to-period fluctuations in the
Company's operating results, including integration of operations resulting from
acquisitions of companies, products or technologies, revenues and expenses
related to the introduction of new products or new versions of existing
products, changes in selling prices, customer delays in purchases in
anticipation of upgrades to existing products, currency fluctuations, dealer and
distributor order patterns, general economic trends or a slowdown of PC sales
and seasonality of customer buying patterns. Historical operating results of the
Company and its predecessors cannot be relied upon as indicative of the future
performance of the Company. On an historical basis, the Company incurred net
losses of $65,960,000 for the year ended January 6, 1996 (after amortization of
$18,229,000 of goodwill) and $405,461,000 for the year ended January 4, 1997
(after amortization of $501,330,000 of goodwill). The Company had net income of
$21,145,000 for the year ended December 31, 1994. There can be no assurance that
the Company will be profitable in the future.


                                      -13-

CAPITAL RESOURCES

     The expansion of the Company's current business involves significant
financial risk and capital investment. There is no assurance that financing will
be available in the future to meet the needs of the Company for additional
investment.

DEPENDENCE ON CONTINUED PERSONAL COMPUTER SALES

     The success of the Company is dependent upon the continuing use of PCs, and
especially multimedia PCs, in the consumer and school markets. A general
decrease in unit sales of PCs or shift to an alternative means of delivery could
adversely affect the Company's future results of operations.

VOLATILITY OF STOCK PRICE

     The Common Stock is quoted on the NYSE. The market price of the Common
Stock, like that for the shares of many other high technology companies, has
been and may continue to be volatile. Recently, the stock market in general and
the shares of personal computer software companies in particular have
experienced significant price fluctuations. These broad market fluctuations, as
well as general economic and political conditions and factors such as quarterly
fluctuations in results of operations, the announcement of technological
innovations, the introduction of new products by the Company or its competitors
and general conditions in the computer hardware and software industries may have
a significant impact on the market price of the Common Stock.



                                USE OF PROCEEDS

   
     Because the Shares will be issued on exchange or redemption of the
New Exchangeable Shares, the Company will receive no net cash proceeds on such
issuance. The Company will bear all costs, fees and expenses incurred in
effecting the registration of the Shares covered by this Prospectus, including,
without limitation, all registration and filing fees, exchange listing fees,
fees and expenses of counsel for the Company, fees and expenses of accountants
for the Company, printing expenses and blue sky fees and expenses.

                              PLAN OF DISTRIBUTION

NEW EXCHANGEABLE SHARES

     The New Exchangeable Shares are issuable upon exercise of the Warrants
offered and sold pursuant to Regulation S under the Securities Act. The Warrants
will be exercisable upon the later of (i) approval by the holders of the
outstanding Exchangeable Shares of SoftKey of the issuance of the New
Exchangeable Shares, and (ii) the date that all other consents and approvals
necessary to ensure that the rights and benefits of the holders of the New
Exchangeable Shares are substantially equivalent to the rights and benefits of
the holders of the outstanding Exchangeable Shares. Notwithstanding the
foregoing, if the conditions specified in (i) and (ii) are not met by March 6,
1998 (or such later date that may be agreed upon by SoftKey and Griffiths
McBurney & Partners and First Marathon Securities Limited, the underwriters for
the sale of the Warrants), the Warrants will be redeemed by SoftKey. The
redemption price per Warrant shall be equal to the purchase price paid for the
Warrant plus interest through the redemption date in accordance with the terms
of the Warrants. The Company has outstanding one Voting Share which has a number
of votes equal to the number of Exchangeable Shares outstanding. The holder of
the Voting Share is not entitled to dividends and shall vote with the holders of
Common Stock as a single class. The Exchangeable Shares may be exchanged for the
Company's Common Stock on a one-for-one basis until February 4, 2005, at which
time all outstanding Exchangeable Shares of SoftKey shall be automatically
exchanged for shares of the Common Stock of the Company.

     The following is a description of certain rights, privileges, restrictions
and conditions of the Exchangeable Shares as set forth in the articles of
arrangement and the plan of arrangement under Section 182 of the Business
Corporations Act (Ontario) dated February 4, 1994 (the "Plan of Arrangement")
providing for the combination of the Company (formerly known as Wordstar
International Incorporated ("Wordstar")), SoftKey and Spinnaker Software
Corporation ("Spinnaker"), and the Voting and Exchange Trust Agreement, dated
February 4, 1994 (the "Voting and Exchange Trust Agreement") among the Company,
SoftKey and R-M Trust Company, as trustee. The Plan of Arrangement and the
Voting and Exchange Trust Agreement were entered into in connection with the
three party combination (the "Three Party Combination") of Wordstar, the
Company, SoftKey and Spinnaker pursuant to the Amended and Restated Combination
Agreement dated as of August 17, 1993. The Plan of Arrangement and the Voting
and Exchange Trust Agreement are included as exhibits to the Registration
Statement of which this Prospectus is a part, and the following description is
qualified in its entirety by reference to the Plan of Arrangement and the Voting
and Exchange Trust Agreement.

PROCEDURES FOR ISSUANCE OF COMMON STOCK

     ELECTION BY HOLDERS TO EXCHANGE EXCHANGEABLE SHARES. Holders of
Exchangeable Shares are entitled at any time with certain limited exceptions to
retract (i.e., require SoftKey to redeem) any or all such Exchangeable Shares
owned by them and to receive for each retracted Exchangeable Share an amount
equal to the Current Market Price (as defined below) of the Company's Common
Stock on the business day prior to the Retraction Date (as defined below) (which
amount shall be satisfied in full by delivery of one share of Common Stock for
each Exchangeable Share), plus an additional amount equal to all declared and
unpaid dividends on such Exchangeable Share (the "Retraction Price"). Holders of
Exchangeable Shares may effect such retraction by presenting a certificate or
certificates to SoftKey or its transfer agent representing the number of
Exchangeable Shares the holder desires to retract, together with a written
statement (the "Retraction Request") specifying the number of Exchangeable
Shares the holder wishes to retract and the date the holder desires to have the
Company redeem the Common Stock, which must be between five and ten business
days after such request is received by SoftKey (the "Retraction Date"), and such
other documents as may be required to effect the retraction of the Exchangeable
Shares. "Current Market Price" means, in respect of a share of the Company's
Common Stock on any date, the Canadian dollar equivalent of the average of the
closing bid and asked prices of the Company's Common Stock during a period of 20
consecutive trading days ending not more than five trading days before such date
on the stock exchange or automated quotation system on which the Company's
Common Stock is listed or quoted.

     SoftKey must immediately notify the Company of any Retraction Request. The
Company will have two business days in which to advise SoftKey as to whether the
Company shall exercise its overriding right (the "Retraction Call Right") to
purchase all of the Exchangeable Shares specified in the Retraction Request by
the delivery of the Retraction Price for each retracted share (a "Retracted
Share") to the transfer agent for payment to the holder on the Retraction Date.
A holder may revoke his or her Retraction Request at any time prior to the close
of business on the business day preceding the Retraction Date, in which case the
holder's Exchangeable Shares will neither be purchased by the Company nor
redeemed by SoftKey. If the holder does not revoke his or her Retraction
Request, on the Retraction Date each Exchangeable Share that the holder has
requested SoftKey to redeem will be acquired by the Company (assuming the
Company exercises its Retraction Call Right) or redeemed by SoftKey, as the case
may be, in each case for the purchase price per Retracted Share equal to the
Retraction Price.

     SoftKey shall not be obligated to redeem Retracted Shares to the extent
that such redemption would be contrary to solvency requirements or other
provisions of applicable law. Retracted Shares not redeemed by SoftKey as a
result of solvency requirements or other provisions of applicable law will be
purchased by the Company on or about the Retraction Date in accordance with the
Voting and Exchange Trust Agreement for a purchase price per Retracted Share
equal to the Retraction Price.

     REDEMPTION OF EXCHANGEABLE SHARES. Subject to applicable law and the
Redemption Call Right of the Company described below, on February 4, 2005 (the
eleventh anniversary of the effective date of the Three Party Combination) or
(i) such later date as specified by the SoftKey Board of Directors or (ii) such
earlier date as specified by the SoftKey Board of Directors, if at such date
there are less than 500,000 Exchangeable Shares outstanding (other than
Exchangeable Shares held by the Company and entities controlled by or under
common control with the Company and subject to necessary adjustments to such
number of shares to reflect permitted changes to Exchangeable Shares) (the
"Automatic Redemption Date"), SoftKey will redeem all but not less than all of
the then outstanding Exchangeable Shares for an amount per share equal to the
Retraction Price. SoftKey shall, at least 120 days prior to the Automatic
Redemption Date, provide the registered holders of the Exchangeable Shares with
written notice of the proposed redemption of the Exchangeable Shares.
Notwithstanding any proposed redemption of the Exchangeable Shares, the Company
has an overriding right to acquire


                                      -16-
<PAGE>   17

on the Automatic Redemption Date all but not less than all of the Exchangeable
Shares then outstanding in exchange for an amount per share equal to the
Retraction Price.

     LIQUIDATION OF SOFTKEY. Upon the liquidation, dissolution or winding up of
SoftKey or any other distribution of the assets of SoftKey among its
stockholders for purposes of winding up its affairs (a "SoftKey Liquidation
Event"), holders of the Exchangeable Shares have the right to receive from
SoftKey, before payment is made to any holder of any class of stock ranking on
liquidation junior to the Exchangeable Shares, for each Exchangeable Share an
amount equal to the Current Market Price of the Company's Common Stock on the
business day prior to the SoftKey Liquidation Event (which shall be satisfied in
full by delivery by the Company of one share of Common Stock for each
Exchangeable Share they hold), plus an additional amount equal to the full
amount of any declared and unpaid dividends on each such Exchangeable Share (the
"Liquidation Amount"). In the event of a proposed SoftKey Liquidation Event, the
Company has the right (the "Liquidation Call Right") to purchase all but not
less than all of the outstanding Exchangeable Shares from the holders thereof at
the effective time of any such SoftKey Liquidation Event in exchange for the
Liquidation Amount.

     On or after the effective date of a SoftKey Liquidation Event, and subject
to the exercise by the Company of its Liquidation Call Right to purchase the
Exchangeable Shares in exchange for the Liquidation Amount, a holder of
Exchangeable Shares may surrender certificates representing such Exchangeable
Shares, together with such other documents as may be required, to SoftKey's
registered office or the office of the transfer agent. Upon receipt of the
certificates and other documents, SoftKey will deliver the Liquidation Amount to
such holder at the address recorded in the securities register or by holding the
Liquidation Amount for pick up by the holder at SoftKey's registered office or
the office of the transfer agent, as specified by SoftKey in a notice to such
holder.

     In a SoftKey Insolvency Event (as defined below), a holder may instruct
CIBC Mellon Trust Company (the "Trustee") to exercise its exchange right by
requiring the Company to purchase the Exchangeable Shares in exchange for the
Liquidation Amount. A "SoftKey Insolvency Event" means the institution by
SoftKey of any proceeding to be adjudicated as bankrupt or insolvent or to be
dissolved or wound up, or the consent of SoftKey to the institution of
bankruptcy, insolvency, dissolution or winding up proceedings against it, or the
filing of a petition, answer or consent seeking dissolution or winding up under
any bankruptcy, insolvency or analogous laws, and the failure by SoftKey to
contest in good faith any such proceedings commenced in respect of SoftKey
within 15 days of becoming aware thereof, or the consent by SoftKey to the
filing of any such petition or to the appointment of a receiver, or the making
by SoftKey of a general assignment for the benefit of creditors, or the
admission in writing by SoftKey of its inability to pay its debts generally as
they become due, or SoftKey not being permitted, pursuant to solvency
requirements of applicable law, to redeem any Exchangeable Shares.

     LIQUIDATION OF THE COMPANY. Upon the occurrence of a Company Liquidation
Event (as defined below), in order for the holders of the Exchangeable Shares
(other than the Company, its subsidiaries and those controlled by or under
common control with the Company) to participate on a pro rata basis with the
holders of Common Stock, each holder of Exchangeable Shares will automatically
receive the Liquidation Amount upon surrender of Exchangeable Shares and such
instruments of transfer as the Company may reasonably require. A "Company
Liquidation Event" means (i) any determination by the Company's Board of
Directors to institute voluntary liquidation, dissolution, or winding-up
proceedings with respect to the Company or to effect any other distribution of
assets of the Company among its stockholders for the purpose of winding up its
affairs; or (ii) immediately upon the earlier of (A) receipt by the Company of
notice of, and (B) the Company becoming aware of any threatened or instituted
claim, suit or proceedings with respect to the involuntary liquidation,
dissolution or winding-up of the Company or to effect any other distribution of
assets of the Company among its stockholders for the purpose of winding up its
affairs.



                                      -17-
<PAGE>   18

     To effect the automatic exchange of Exchangeable Shares for shares of
Common Stock, the Company will be deemed to have purchased each Exchangeable
Share outstanding on the fifth business day prior to the effective date of the
Company Liquidation Event for the Liquidation Amount.

                            INCOME TAX CONSIDERATIONS

CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

     In the opinion of Davies, Ward & Beck, Canadian tax counsel for SoftKey,
the following is a summary of the principal Canadian federal income tax
considerations generally applicable to a holder who acquires New Exchangeable
Shares as described under the heading "Plan of Distribution" (a "Holder") who,
for purposes of the Canadian Tax Act, holds his or her New Exchangeable Shares
and will hold his or her shares of Common Stock as capital property and who
deals at arm's length with SoftKey and the Company. This summary does not apply
to a Holder with respect to whom the Company is a "foreign affiliate" within the
meaning of the Canadian Tax Act.

     This summary is based on the current provisions of the Income Tax Act
(Canada) (the "Canadian Tax Act"), the regulations thereunder, all specific
proposals to amend the Canadian Tax Act or the regulations publicly announced by
the Minister of Finance (Canada) prior to the date hereof (the "Tax Proposals"),
and counsel's understanding of the current administrative practices of Revenue
Canada. The Canadian Tax Act contains certain provisions relating to securities
held by certain financial institutions (the "Mark-to-Market Rules"). This
summary does not take into account these Mark-to-Market Rules, and Holders that
are "financial institutions" for purposes of such rules should consult their own
tax advisors.

     This summary is not exhaustive of all possible Canadian federal income tax
considerations and, except for the Tax Proposals, does not take into account or
anticipate any changes in law, whether by legislative, administrative or
judicial decision or action, nor does it take into account provincial,
territorial or foreign income tax legislation or considerations, which may
differ from the federal income tax considerations described herein.

     THIS SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, NOR
SHOULD IT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY PARTICULAR HOLDER.
HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THEIR PARTICULAR
CIRCUMSTANCES.

     For purposes of the Canadian Tax Act, all amounts relating to the
acquisition, holding or disposition of shares of Common Stock, including
dividends, adjusted cost base and proceeds of disposition, must be converted
into Canadian dollars based on the prevailing United States dollar exchange rate
at the time such amounts arise.

     HOLDERS RESIDENT IN CANADA

     The following portion of the summary is applicable to Holders who, for
purposes of the Canadian Tax Act, are resident or deemed to be resident in
Canada.

     Dividends - Exchangeable Shares

     Dividends received or deemed to be received on the New Exchangeable Shares
by a Holder who is an individual will be included in computing the Holder's
income, and will be subject to the gross-up and dividend tax credit rules
normally applicable to taxable dividends received from taxable Canadian
corporations.



                                      -18-
<PAGE>   19
     The New Exchangeable Shares will be "taxable preferred shares" and
"short-term preferred shares" for purposes of the Canadian Tax Act. Accordingly,
SoftKey will be subject to a 66-2/3% tax under Part VI.1 of the Canadian Tax Act
on dividends paid or deemed to be paid on the New Exchangeable Shares. Dividends
received or deemed to be received by a Holder on New Exchangeable Shares will
not be subject to the 10% tax under Part IV.1 of the Canadian Tax Act applicable
to certain corporations.

     Dividends received or deemed to be received on the New Exchangeable Shares
by a Holder that is a corporation, other than a "specified financial
institution" as defined in the Canadian Tax Act, will normally be deductible in
computing its taxable income if either:

     (a) at and immediately before the time at which the dividend is paid or
     deemed to be paid the Company is not a specified financial institution or a
     specified person in relation to a specified financial institution for
     purposes of the Canadian Tax Act; or

     (b) at the time of receipt of the dividend, the Exchangeable Shares are
     listed on a prescribed stock exchange in Canada (which currently includes
     the TSE) and the Holder, either alone or together with specified persons in
     relation to the Holder, does not receive (or is not deemed to receive)
     dividends in respect of more than 10% of the issued and outstanding
     Exchangeable Shares.

     The Company has advised Canadian tax counsel that it is of the view that it
is a specified financial institution for purposes of the Canadian Tax Act at the
current time. This status may change in the future.

     In the case of a Holder that is a specified financial institution, such a
dividend will normally be deductible in computing its taxable income if either:

     (a) the specified financial institution did not acquire the Exchangeable
     Shares in the ordinary course of the business carried on by the Holder; or

     (b) at the time of receipt of the dividend by the specified financial
     institution, the Exchangeable Shares are listed on a prescribed stock
     exchange in Canada (which currently includes the TSE) and the specified
     financial institution, either alone or together with persons with whom it
     does not deal at arm's length, does not receive (or is not deemed to
     receive) dividends in respect of more than 10% of the issued and
     outstanding Exchangeable Shares.

     A Holder that is a "private corporation" or a "subject corporation" (as
defined in the Canadian Tax Act) may be liable under Part IV of the Canadian Tax
Act to pay a refundable tax of 33-1/3% on dividends received or deemed to be
received on the New Exchangeable Shares to the extent that such dividends are
deductible in computing the Holder's taxable income.

     Dividends - Common Stock

     Dividends on Common Stock will be included in the recipient's income for
the purposes of the Canadian Tax Act. Such dividends received by a Holder who is
an individual will not be subject to the gross-up and dividend tax credit rules
in the Canadian Tax Act. A Holder that is a corporation will include such
dividends in computing its income and generally will not be entitled to deduct
the amount of such dividends in computing its taxable income. United States
non-resident withholding tax on such dividends will be eligible for foreign tax
credit or deduction treatment where applicable under the Canadian Tax Act.

     Redemption or Exchange of New Exchangeable Shares

     On the redemption (including a retraction) of a New Exchangeable Share by
SoftKey for a share of Common Stock, the Holder will be deemed to have received
a dividend equal to the amount, if any, by which the redemption proceeds (the
fair market value at the time of the redemption of the share of Common Stock
received by the Holder from SoftKey on the redemption plus the amount, if any,
of all unpaid dividends on the New Exchangeable Share) exceeds the paid-up
capital at that time of the New Exchangeable Share so redeemed. The amount of
any such deemed dividend will be subject to the tax treatment accorded to the
dividends described above under " - Canadian Federal Income Tax Considerations -
Shareholders Resident in Canada - Dividends - Exchangeable Shares." On the
redemption, the Holder will also be considered to have disposed of the New
Exchangeable Share, but the amount of such deemed dividend will be excluded in
computing the Holder's proceeds of disposition for purposes of computing any
capital gain or capital loss arising on the disposition of the New Exchangeable
Share. In the case of a Holder that is a corporation, in some circumstances all
or a portion of the amount of any such deemed dividend may be treated as
proceeds of disposition and not as a dividend.

     On the exchange of a New Exchangeable Share by a Holder with the Company
for a share of Common Stock, the Holder generally will realize a capital gain
(or a capital loss) equal to the amount by which the proceeds of disposition of
the New Exchangeable Share, net of any reasonable costs of disposition, exceed
(or are less than) the adjusted cost base of the New Exchangeable Share to the
Holder. For these purposes, the proceeds of disposition will be the value of the
share of Common Stock at the time of exchange plus the amount of all unpaid
dividends on the New Exchangeable Share.

     The cost to a Holder of a share of Common Stock received on the retraction,
redemption or exchange of a New Exchangeable Share will be equal to the fair
market value of the share of Common Stock at the time of such event. Where the
share of Common Stock is capital property, its cost will be averaged with the
adjusted cost base of all such shares held by the Holder as capital property
immediately before the acquisition to determine the adjusted cost base of each
such share to the Holder.

     BECAUSE OF THE EXISTENCE OF THE RETRACTION CALL RIGHT, A HOLDER EXERCISING
THE RIGHT OF RETRACTION IN RESPECT OF A NEW EXCHANGEABLE SHARE CANNOT CONTROL
WHETHER SUCH HOLDER WILL RECEIVE A SHARE OF COMMON STOCK BY WAY OF REDEMPTION OF
THE NEW EXCHANGEABLE SHARE BY SOFTKEY OR BY WAY OF PURCHASE OF THE NEW
EXCHANGEABLE SHARE BY THE COMPANY. AS DESCRIBED ABOVE, THE CANADIAN FEDERAL
INCOME TAX CONSEQUENCES OF A REDEMPTION DIFFER FROM THOSE OF A PURCHASE.
HOWEVER, A HOLDER WHO EXERCISES THE RIGHT OF RETRACTION WILL BE NOTIFIED IF THE
RETRACTION CALL RIGHT WILL NOT BE EXERCISED BY THE COMPANY, AND IF SUCH HOLDER
DOES NOT WISH TO PROCEED, SUCH HOLDER MAY CANCEL THE NOTICE OF RETRACTION AND
RETAIN SUCH HOLDER'S NEW EXCHANGEABLE SHARE (SEE "PROCEDURES FOR ISSUANCE OF
COMMON STOCK - ELECTION BY HOLDERS TO EXCHANGE EXCHANGEABLE SHARES").

     Dispositions and Taxation of Capital Gains and Capital Losses

     Upon a disposition (or a deemed disposition) of a New Exchangeable Share or
a share of Common Stock, including a sale, exchange or other disposition, a
Holder generally will realize a capital gain (or a capital loss) equal to the
amount by which the proceeds of disposition of the New Exchangeable Share or the
share of Common Stock, as applicable, net of any reasonable costs of
disposition, exceed (or are less than) the adjusted cost base of the New
Exchangeable Share or the share of Common Stock, as applicable, to the Holder.
Three-quarters of any such capital gain will be required to be included in
computing the Holder's income as a taxable capital gain. Three-quarters of any
such capital loss normally is deducted against taxable capital gains realized by
the Holder in the year of disposition and thereafter normally may be deducted by
the Holder against taxable capital gains realized in any 



                                      -20-
<PAGE>   21
 of the three preceding taxation years or any subsequent taxation year, subject
to detailed rules contained in the Canadian Tax Act in this regard.

     The amount of any capital loss realized on the disposition or deemed
disposition of a New Exchangeable Share by a Holder that is a corporation may be
reduced by the amount of dividends received or deemed to have been received by
it on such share to the extent and in the circumstances prescribed by the
Canadian Tax Act. Similar rules may apply where a Holder that is a corporation
is a member of a partnership or beneficiary of a trust that owns New
Exchangeable Shares or that is itself a member of a partnership or a beneficiary
of a trust that owns New Exchangeable Shares.

     A Canadian-controlled private corporation (as defined in the Canadian Tax
Act) also may be liable to pay a 6-2/3% refundable tax on certain investment
income including taxable capital gains.

     Foreign Property

     The New Exchangeable Shares, if issued on the date hereof and listed on a
prescribed stock exchange in Canada (which currently includes the TSE), would
not, on the date hereof, be foreign property under the Canadian Tax Act for
trusts governed by registered pension plans, registered retirement savings
plans, registered retirement income funds and deferred profit sharing plans or
for certain other tax-exempt persons. The Holders rights with respect to the
Voting Share (the "voting rights") and the Holder's right to require the Company
to acquire New Exchangeable Shares upon the occurrence of a SoftKey Insolvency
Event (the "exchange rights") will be foreign property under the Canadian Tax
Act. SoftKey has advised Canadian tax counsel that Softkey is of the view that
the fair market value of the voting rights and the exchange rights is nominal.
Common Stock will be foreign property under the Canadian Tax Act.

     Qualified Investments

     The New Exchangeable Shares, if issued on the date hereof and listed on a
prescribed stock exchange in Canada (which currently includes the TSE), would
be, on the date hereof, a qualified investment under the Canadian Tax Act for
trusts governed by registered retirement savings plans, registered retirement
income funds and deferred profit sharing plans. Shares of Common Stock, if
issued on the date hereof and listed on a prescribed stock exchange (which
currently includes the NYSE) would be, on the date hereof, qualified investments
for such trusts. The voting rights and the exchange rights will not be qualified
investments under the Canadian Tax Act. As indicated above, SoftKey is of the
view that the fair market value of these rights is nominal.

     SHAREHOLDERS NOT RESIDENT IN CANADA

     The following summary is applicable to Holders who, for purposes of the
Canadian Tax Act, have not been and will not be resident in Canada at any time
while they hold New Exchangeable Shares or will hold shares of Common Stock, who
do not use or hold and are not deemed to use or hold such shares in the course
of carrying on a business in Canada, and to whom such shares are not taxable
Canadian property. Additional considerations, which are not discussed below, may
be relevant to a non-resident that is an insurer which carries on business in
Canada and elsewhere. Generally, the New Exchangeable Shares and shares of
Common Stock will not be taxable Canadian property provided that the Holder does
not use or hold, and is not deemed to use or hold, the New Exchangeable Shares
or the shares of Common Stock, as applicable, in connection with carrying on a
business in Canada and, in the case of the New Exchangeable Shares, the Holder,
persons with whom such holder does not deal at arm's length, or the Holder and
such persons, has not owned (or had under option) 25% or more of the issued
shares of any class or series of the capital stock of SoftKey at any time within
five years preceding the date in question.



                                      -21-
<PAGE>   22
 Such a Holder of Exchangeable Shares will not be subject to tax under the
Canadian Tax Act on capital gains arising on the exchange of a New Exchangeable
Share by the Company for a share of Common Stock, or on the sale or other
disposition of a New Exchangeable Share or a share of Common Stock. Such a
Holder may be subject to withholding tax under the Canadian Tax Act on a
redemption of New Exchangeable Shares, as described below.

     Dividends paid on the New Exchangeable Shares are subject to non-resident
withholding tax under the Canadian Tax Act at the rate of 25%, although such
rate may be reduced under the provisions of an applicable income tax treaty. For
example, under the Canada-United States Income Tax Convention, the rate is
generally reduced to 15%.

     A HOLDER WHOSE NEW EXCHANGEABLE SHARES ARE REDEEMED (EITHER UNDER SOFTKEY'S
REDEMPTION RIGHT OR PURSUANT TO THE HOLDER'S RETRACTION RIGHTS) WILL BE DEEMED
TO RECEIVE A DIVIDEND AS DESCRIBED ABOVE UNDER " - CANADIAN FEDERAL INCOME TAX
CONSIDERATIONS - SHAREHOLDERS RESIDENT IN CANADA - REDEMPTION OR EXCHANGE OF
EXCHANGEABLE SHARES," WHICH DEEMED DIVIDEND WILL BE SUBJECT TO WITHHOLDING TAX
AS DESCRIBED IN THE PRECEDING PARAGRAPH.

UNITED STATES FEDERAL TAX CONSIDERATIONS

   
     The following is a summary of the material United States federal income and
estate tax considerations relating to the exchange of New Exchangeable Shares
for Common Stock and the purchase, ownership and disposition of Common Stock,
but does not purport to be a complete analysis of all the potential tax
considerations relating thereto. This summary is based on the provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), the applicable Treasury
Regulations promulgated or proposed thereunder ("Treasury Regulations"),
judicial authority and current administrative rulings and practice, all of which
are subject to change, possibly on a retroactive basis. This summary deals only
with holders that will hold New Exchangeable Shares or Common Stock as "capital
assets" (within the meaning of Section 1221 of the Code) and does not address
tax considerations applicable to investors that may be subject to special tax
rules, such as banks, tax-exempt organizations, insurance companies, dealers in
securities or currencies, persons that will hold New Exchangeable Shares or
Common Stock as a position in a hedging transaction, "straddle" or "conversion
transaction" for tax purposes, or persons that have a "functional currency"
other than the U.S. dollar. The Company has not sought any ruling from the
Internal Revenue Service ("IRS") with respect to the statements made and the
conclusions reached in the following summary, and there can be no assurance that
the IRS will agree with such statements and conclusions. The summary represents
the opinion of Hale and Dorr LLP, United States counsel to the Company.
    

   
INVESTORS CONSIDERING THE EXCHANGE OF NEW EXCHANGEABLE SHARES FOR COMMON STOCK
SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE
UNITED STATES FEDERAL INCOME AND ESTATE TAX LAWS TO THEIR PARTICULAR SITUATIONS
AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCAL OR
FOREIGN TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.
    

NON-UNITED STATES HOLDERS

   
     As used herein, the term "Non-United States Holder" means a beneficial
owner of New Exchangeable Shares or Common Stock other than a beneficial owner
that for United States federal income tax purposes is (i) a citizen or resident
of the United States, (ii) treated as a domestic corporation or domestic
partnership, or (iii) an estate or trust that is subject to United States
federal income taxation on a net income basis in respect of Common Stock.

     Exchange of New Exchangeable Shares
    

   
     A Non-United States Holder generally will not be subject to United States
federal income tax or withholding tax on the exchange of New Exchangeable Shares
for shares of Common Stock unless (1) the gain is effectively connected with a
United States trade or business of the Non-United States Holder, (2) in the case
of a Non-United States Holder who is an individual, such Holder is present in
the United States for a period or periods aggregating 183 days or more during
the taxable year of the disposition or (3) the Holder is subject to tax pursuant
to the provisions of the Code applicable to certain United States expatriates.
    

     Dividends

     The amount of any distribution by the Company in respect of the Common
Stock will be equal to the amount of cash and the fair market value, on the date
of distribution, of any property distributed. Generally, distributions will be
treated as a dividend to the extent of the Company's current or accumulated
earnings and profits, then as a tax-free return of capital to the extent of the
Holder's tax basis in the Common Stock and thereafter as gain from the sale of
exchange of such stock. Distributions treated as dividends paid, excluding
dividends that are effectively connected with the conduct of a trade or business
in the United States by such Holder, will be subject to United States federal
withholding tax at a 30% rate (or lower rate provided under any applicable
income tax treaty). Except to the extent that an applicable tax treaty otherwise
provides, a Non-United States Holder will be taxed in the same manner as a
United States Holder on dividends paid that are effectively connected with the
conduct of a trade or business in the United States by the Non-United States
Holder. If such Non-United States Holder is a foreign corporation, it may also
be subject to a United States branch profits tax on such effectively connected
income at a 30% rate or such lower rate as may be specified by an applicable
income tax treaty. Even though such effectively connected dividends are subject
to income tax, and may be subject to the branch profits tax, they will not be
subject to U.S. withholding tax if the Holder delivers IRS Form 4224 to the
payor.

     Under current U.S. Treasury regulations, dividends paid to an address in a
foreign country are presumed to be paid to a resident of that country (unless
the payor has knowledge to the contrary) for purposes of the withholding
discussed above and, under the current interpretation of U.S. Treasury
Regulations, for purposes of determining the applicability of a tax treaty rate.
Under recently issued U.S. Treasury Regulations, however, Non-U.S. Holders of
Common Stock who wish to claim the benefit of an applicable treaty rate would be
required to satisfy certain certification requirements. The new U.S. Treasury
Regulations are effective for payments made after December 31, 1998.

     SALE OF COMMON STOCK

     A Non-United States Holder generally will not be subject to United States
federal income tax or withholding tax on the sale or exchange of Common Stock
unless (1) the gain is effectively connected with a United States trade or
business of the Non-United States Holder, (2) in the case of a Non-United States
Holder who is an individual, such Holder is present in the United States for a
period or periods aggregating 183 days or more during the taxable year of the
disposition or (3) the Holder is subject to tax pursuant to the provisions of
the Code applicable to certain United States expatriates.

     DEATH OF A NON-UNITED STATES HOLDER

     Common Stock actually or beneficially held (other than through a foreign
corporation) by a Non-United States Holder at the time of his or her death (or
previously transferred subject to certain 


                                        
                                      -23-

<PAGE>   24

retained rights or powers) will be subject to United States federal estate tax
unless otherwise provided by an applicable estate tax treaty.

     INFORMATION REPORTING AND BACKUP WITHHOLDING TAX

   
     United States information reporting requirements and backup withholding tax
will not apply to any exchange of New Exchangeable Shares or the payment of the
proceeds of the sale of Common Stock effected outside the United States by a
foreign office of a "broker" (as defined in applicable U.S. Treasury
Regulations); unless such broker (i) is a United States person, (ii) is a
foreign person that derives 50% or more of its gross income for certain periods
from the conduct of a trade or business in the United States or (iii) is a
controlled foreign corporation for United States federal income tax purposes.
Payment of the proceeds of any such sale effected outside the United States by a
foreign office of any broker that is described in (i), (ii) or (iii) of the
preceding sentence will not be subject to backup withholding tax, but will be
subject to information reporting requirements unless such broker has documentary
evidence in its records that the beneficial owner is a Non-United States Holder
and certain other conditions are met, or the beneficial owner otherwise
establishes an exemption. Payment of the proceeds of any such sale to or through
the United States office of a broker is subject to information reporting and
backup withholding requirements, unless the beneficial owner of Common Stock (a)
provides a Form W-8 (or a suitable substitute form) signed under penalties of
perjury that includes its name and address and certifies as to its non-United
States status, or (b) is a securities clearing organization, bank or other
financial institution that holds customers' securities in the ordinary course of
its trade or business and provides a statement to the Company or its agent under
penalties of perjury in which it certifies that a Form W-8 (or a suitable
substitute) has been received by it from the Non-United States Holder or
qualifying intermediary and furnishes the Company or its agent with a copy
thereof.
    

     If paid to an address outside the United States, dividends on Common Stock
held by a Non-United States Holder will generally not be subject to the
information reporting and backup withholding requirements described in this
section. However, under recently issued U.S. Treasury Regulations, dividend
payments will be subject to information reporting and backup withholding unless
applicable certification requirements are satisfied. The new U.S. Treasury
Regulations apply to dividend payments made after December 31, 1998.

     UNITED STATES REAL PROPERTY HOLDING CORPORATIONS

     The discussion of the United States taxation of Non-United States Holders
of Common Stock assumes that the Company is at no time a United States real
property holding corporation within the meaning of Section 897(c) of the Code.
Under present law, the Company would not be a United States real property
holding corporation so long as (a) the fair market value of its United Stated
real property interests is less than (b) 50% of the sum of the fair market value
of its United States real property interests, its interests in real property
located outside the United States, and its other assets which are used or held
or use in a trade or business. The Company believes that it is not a United
States real property holding corporation and does not expect to become such a
corporation.

UNITED STATES HOLDERS

     As used herein, the term "United States Holder" means any beneficial owner
of Common Stock that is not a Non-United States Holder.

   
     EXCHANGE OF NEW EXCHANGEABLE SHARES
    




                                      -24-
<PAGE>   25

   
     A United States Holder will generally recognize capital gain or loss upon
the exchange of New Exchangeable Shares for shares of Common Stock equal to the
difference between the fair market value of shares of Common Stock received
(other than Common Stock received for declared but unpaid dividends) and such
Holder's basis in the New Exchangeable Shares surrendered.
    

   
     Under certain limited circumstances, an exchange by a United States Holder
of New Exchangeable Shares for Common Stock may be characterized as a tax free
exchange (except to the extent of Common Stock received in exchange for
declared, but unpaid, dividends). It is not possible to predict whether or not
all of the requirements for a tax-free exchange will exist at the time of the
exchange, because such requirements are dependent upon future events. If the
exchange qualifies as a tax-free exchange, a United States Holder will not
recognize gain or loss upon the exchange, will have a basis in the Common Stock
received in the exchange equal to such Holder's basis in the New Exchangeable
Shares, and will have a holding period which includes the holding period in the
New Exchangeable Shares.
    

   
     Whether the exchange of New Exchangeable Shares is taxable or tax-free, a
United States Holder will recognize ordinary income to the extent of Common
Stock received in the exchange for declared, but unpaid, dividends on the New
Exchangeable Shares. A United States Holder's holding period in all shares of
Common Stock received in the exchange will begin on the day after the exchange.
    

     Canadian tax, if any, imposed on the exchange may be available as a credit
against a United States Holder's United States federal income taxes, subject to
applicable limitations. A United States Holder who is not eligible for a credit
may be able to deduct the Canadian taxes paid, if any, in computing United
States federal income subject to tax.

     PASSIVE FOREIGN INVESTMENT COMPANY

   
     SoftKey may be classified as a passive foreign investment company ("PFIC")
for United States federal income tax purposes for any taxable year if either (i)
75% or more of its gross income is passive income or (ii) on average for the
taxable year, 50% or more of its assets (by value) produce or are held for the
production of passive income. While there can be no assurance, the Company and
SoftKey expect, based on the manner in which SoftKey intends to manage its
business and the projections of SoftKey's investments, income and assets, that
it will not be a PFIC. SoftKey will monitor its status and will notify holders
of New Exchangeable Shares if it believes that it is properly classified as a
PFIC for any taxable year.
    

   
     If SoftKey were to be classified as a PFIC, the consequences to a United
States Holder will depend in part on whether the United States Holder has made a
"Mark-to-Market Election" or a "QEF Election" with respect to SoftKey. If
SoftKey is a PFIC during a United States Holder's holding period and the United
States Holder does not make a Mark-to-Market Election or a QEF Election, the
United States Holder will generally be required to pay a special United States
tax, in lieu of the U.S. tax that would otherwise apply, if such United States
Holder (a) realizes a gain upon the sale or exchange of New Exchangeable Shares
(including an exchange for Common Stock) or (b) receives an "excess
distribution" from SoftKey on the New Exchangeable Shares. If a United States
Holder makes a QEF Election or Mark-to-Market Election, it will generally be
required to include amounts in income, based upon SoftKey's income or the value
of the New Exchangeable Shares, even if SoftKey does not make actual
distributions to holders of New Exchangeable Shares.
    

     If for any year SoftKey determines that it is properly classified as a
PFIC, SoftKey will comply with all reporting requirements necessary for a United
States Holder to make a QEF Election and will, promptly following the end of
such year and each year thereafter for which it is properly classified as a
PFIC, provide to United States Holders the information required by the QEF
Election.

<PAGE>   26

     DIVIDENDS

     The amount of any distribution by the Company in respect of the Common
Stock will be equal to the amount of cash and the fair market value, on the date
of distribution, of any property distributed. Generally, distributions will be
treated as a dividend, subject to tax as ordinary income, to the extent of the
Company's current or accumulated earnings and profits, then as a tax-free return
of capital to the extent of the Holder's tax basis in the Common Stock and
thereafter as gain from the sale of exchange of such stock.

     SALE OF COMMON STOCK

     Upon the sale or exchange of Common Stock, a United States Holder generally
will recognize capital gain or loss equal to the difference between (i) the
amount of cash and the fair market value of any property received upon the sale
or exchange and (ii) such Holder's adjusted tax basis in the Common Stock.

     INFORMATION REPORTING AND BACKUP WITHHOLDING TAX

   
     In general, information reporting requirements will apply to (i) payments
of dividends on Common Stock and (ii) the exchange of New Exchangeable Shares
for Common Stock or payments of the proceeds of the sale of Common Stock by or
to certain noncorporate United States Holders. The payor will be required to
withhold backup withholding tax at the rate of 31% if the payee fails to furnish
certain information to the payor or the IRS notifies the payor that backup
withholding is required. Any amounts withheld under the backup withholding rules
from a payment to a United States Holder will be allowed as a credit against
such Holder's United States federal income tax and may entitle the Holder to a
refund, provided that the required information is furnished to the IRS.
    


LEGAL MATTERS

   
     Certain legal matters in connection with the Common Stock offered hereby
are being passed upon for the Company by Neal S. Winneg, General Counsel of the

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 102 of the Delaware General Corporation Law, as amended, allows a
corporation to eliminate the personal liability of directors of a corporation to
the corporation or its stockholders for monetary damages for a breach of
fiduciary duty as a director, except where the director breached his duty of
loyalty, failed to act in good faith, engaged in intentional misconduct or
knowingly violated a law, authorized the payment of a dividend or approved a
stock repurchase in violation of Delaware corporate law or obtained an improper
personal benefit.

     Section 145 of the Delaware General Corporation Law, as amended, provides
that a corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation), by reason of the
fact that he is or was a director, officer, employee or agent of the corporation
or is or was serving at its request in such capacity in another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful.

     Section 8 of the Company's Restated Certificate of Incorporation, as
amended, provides for elimination of directors' personal liability and
indemnification as follows:



                                      II-1
<PAGE>   29

     "8.  LIMITATION OF LIABILITY AND INDEMNIFICATION OF DIRECTORS

     8.1 ELIMINATION OF CERTAIN LIABILITIES OF DIRECTORS. A director of the
Corporation shall not be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the directors' duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or (iv) for any transaction
from which the director derived an improper personal benefit. If the Delaware
General Corporation Law is amended after approval by the stockholders of this
Section to authorize corporate action further eliminating or limiting the
personal liability of directors, then the liability of a director of the
Corporation shall be eliminated or limited to the fullest extent permitted by
the Delaware General Corporation Law, as so amended. Any repeal or modification
of this Section by the stockholders of the Corporation shall not adversely
affect any right or protection of a director of the Corporation existing at the
time of such repeal or modification.

     8.2  INDEMNIFICATION AND INSURANCE.

          8.2.1 RIGHT TO INDEMNIFICATION. Each person who was or is made a party
or is threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative, or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she, or a person
of whom he or she is the legal representative, is or was a director or officer
of the Corporation or is or was serving at the request of the Corporation, as a
director, officer, employee or agent of another corporation or of a partnership,
joint venture, trust, or other enterprise, including service with respect to
employee benefit plans, whether the basis of such proceeding is alleged action
in an official capacity as a director, officer, employee, or agent or in any
other capacity while serving as a director, officer, employee or agent, shall be
indemnified and held harmless by the Corporation to its fullest extent
authorized by the Delaware General Corporation Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the extent
that such amendment permits the Corporation to provide broader indemnification
rights than said law permitted the Corporation to provide prior to such
amendment), against all expense, liability, and loss (including attorneys' fees,
judgments, fines, Employee Retirement Income Security Act of 1974, excise taxes
or penalties, and amounts paid or to be paid in settlement) reasonably incurred
or suffered by such person in connection therewith, and such indemnification
shall continue as to a person who has ceased to be a director, officer, employee
or agent and shall inure to the benefit of his or her heirs, executors, and
administrators; provided, however, that the Corporation shall indemnify any such
person seeking indemnification in connection with a proceeding (or part thereof)
initiated by such person only if such proceeding (or part thereof) was
authorized by the Board of Directors of the Corporation. The right to
indemnification conferred in this Section shall be a contract right and shall
include the right to be paid by the Corporation the expenses incurred defending
any such proceeding in advance of its final disposition; provided, however,
that, if the Delaware General Corporation Law requires, the payment of such
expenses incurred by a director or officer in his or her capacity as a director
or officer (and not in any other capacity in which service was or is rendered by
such person while a director or officer, including, without limitation, service
to an employee benefit plan) in advance of the final disposition of a
proceeding, shall be made only upon delivery to the Corporation of an
undertaking, by or on behalf of such director or officer, to repay all amounts
so advanced if it shall ultimately be determined that such director or officer
is not entitled to be indemnified under this Section or otherwise. The
Corporation may, by action of its Board of Directors, provide indemnification to
employees and agents of the Corporation with the same scope and effect as the
foregoing indemnification of directors and officers.

          8.2.2 NON-EXCLUSIVITY OF RIGHTS. The right to indemnification and the
payment of expenses incurred in defending a proceeding in advance of its final
disposition conferred in this



                                      II-2
<PAGE>   30

Section shall not be exclusive of any other right which any person may have or
hereafter acquire under any statute, provision of this Restated Certificate,
Bylaw, agreement, vote of stockholders, or disinterested directors or otherwise.

          8.2.3 INSURANCE. The Corporation may maintain insurance, at its
expense, to protect itself and any director, officer, employee, or agent of the
Corporation or another corporation, partnership, joint venture, trust, or other
enterprise against any such expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability, or loss under the Delaware General Corporation Law."

     The Company has purchased directors' and officers' liability insurance
which would indemnify the directors and officers of the Company against damages
arising out of certain kinds of claims which might be made against them based on
their negligent acts or omissions while acting in their capacity as such. In
addition, certain of the Company's directors may be entitled to indemnification
and advancement of expenses under the charter documents of Tribune Company and
may be covered by directors' and officers' liability insurance maintained by
Tribune Company.

ITEM 17.  UNDERTAKINGS.

     The undersigned Registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

               (i) To include any prospectus required by Section 10(a)(3) of the
          Securities Act of 1933, as amended (the "Securities Act");

               (ii) To reflect in the prospectus any facts or events arising
          after the effective date of this Registration Statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in this Registration Statement. Notwithstanding the foregoing, any
          increase or decrease in the volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any derivation from the low or high and of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume and price represent no more than
          20 percent change in the maximum aggregate offering price set forth in
          the "Calculation of Registration Fee" table in the effective
          Registration Statement; and

               (iii) To include any material information with respect to the
          plan of distribution not previously disclosed in this Registration
          Statement or any material change to such information in this
          Registration Statement.

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

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

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

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

Exchangeable Shares in connection with the exercise by the Beneficiary of the
Exchange Right or the occurrence of the automatic exchange of Exchangeable
Shares for Parent Common Shares, as specified in Article 5 hereof (unless in

                      EXCHANGE RIGHT AND AUTOMATIC EXCHANGE

5.1    GRANT AND OWNERSHIP OF THE EXCHANGE RIGHT. The Parent hereby grants to
the Trustee as trustee for and on behalf of, and for the use and benefit of, the
Beneficiaries the right (the "Exchange Right"), upon the occurrence and during
the continuance of an Insolvency Event, to require the Parent to purchase from
each or any Beneficiary all or any part of the Exchangeable Shares held by the
Beneficiary and the Automatic Exchange Rights, all in accordance with the
provisions of this agreement. The Parent hereby acknowledges receipt from the
Trustee as trustee for and on behalf of the Beneficiaries of good and valuable
consideration (and the adequacy thereof) for the grant of the Exchange Right and
the Automatic Exchange Rights by the Parent to the Trustee. During the term of
the Trust and subject to the terms and conditions of this trust agreement, the
Trustee shall possess and be vested with full legal ownership of the Exchange
Right and the Automatic 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 Right 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 trust
             agreement; and

       (b)   except as specifically authorized by this trust 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 trust
             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

       (b)   the Automatic Exchange Rights.

5.3    GENERAL EXERCISE OF EXCHANGE RIGHT. The Exchange Right shall be and
remain vested in and exercised by the Trustee. Subject to section 7.15, the
Trustee shall exercise the Exchange Right only:



                                      -13-

<PAGE>   14



       (a)   on the basis of instructions received pursuant to this Article 5
             from Beneficiaries entitled to instruct the Trustee as to the
             exercise thereof; or

       (b)   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 the Parent for each
Exchangeable Share to be purchased by the Parent under the Exchange Right shall
be an amount per share equal to (a) the Current Market Price of a Parent Common
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 (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 the declared and unpaid dividends). In connection with each
exercise of the Exchange Right, the Parent 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 the Parent issuing and delivering or causing
to be delivered to the Trustee, on behalf of the relevant Beneficiary, one
Parent Common Share and a cheque for the balance, if any, of the purchase price.

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 the Parent 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 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, 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 the Parent 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 the Parent free and
clear of all liens, claims and encumbrances, (iii) the names in which the
certificates representing the Parent Common Shares issuable in connection with
the exercise of the Exchange Right




                                      -14-

<PAGE>   15


are to be issued and (iv) the names and addresses of the persons to whom such
new certificates should be delivered and (b) payment (or evidence satisfactory
to the Trustee, the Corporation and the Parent of payment) of the taxes (if any)
payable as contemplated by section 5.8 of this trust agreement. If only a part
of the Exchangeable Shares represented by any certificate or certificates
delivered to the Trustee are to be purchased by the Parent under the Exchange
Right, a new certificate for the balance of such Exchangeable Shares shall be
issued to the holder at the expense of the Corporation.

5.6    DELIVERY OF PARENT COMMON SHARES: EFFECT OF EXERCISE. Promptly after
receipt of the certificates representing the Exchangeable Shares which the
Beneficiary desires the Parent 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 the Parent, the Trustee shall
notify the Parent and the Corporation of its receipt of the same, which notice
to the Parent and the Corporation shall constitute exercise of the Exchange
Right by the Trustee on behalf of the holder of such Exchangeable Shares, and
the Parent 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), the
certificates for the number of Parent Common Shares issuable 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 balance, if any, of the total purchase price
therefor; provided, however, that no such delivery shall be made unless and
until the Beneficiary requesting the same shall have paid (or provided evidence
satisfactory to the Trustee, the Corporation and the Parent of the payment of)
the taxes (if any) payable as contemplated by section 5.8 of this trust
agreement. Immediately upon the giving of notice by the Trustee to the Parent
and the Corporation of the exercise of the Exchange Right, as provided in this
section 5.6, the 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 the Parent 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, unless the requisite number of Parent Common
Shares (together with a cheque for the balance, if any, of the total purchase
price therefor) is not allotted, issued and delivered by the Parent 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, in which case the rights of the
Beneficiary shall remain unaffected until such Parent Common Shares are so
allotted, issued and delivered by the Parent and any such cheque is so delivered
and paid. Concurrently with such Beneficiary ceasing to be a holder of
Exchangeable Shares, the Beneficiary shall be considered and deemed for all



                                      -15-

<PAGE>   16


purposes to be the holder of the Parent Common 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 Share 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 the Parent
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 or to the transfer agent of the Exchangeable Shares (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 the Parent 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
the Parent pursuant to the Exchange Right or the Automatic Exchange Rights, the
share certificate or certificates representing the Parent Common 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 names 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 the Parent, 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, the
Parent 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 the Parent shall
give written notice thereof to the Trustee. As soon as practicable after
receiving notice from the Corporation and



                                      -15-

<PAGE>   17



the Parent or from any other person of the occurrence of an Insolvency Event,
the Trustee will mail to each Beneficiary, at the expense of the Parent, 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.

5.10   QUALIFICATION OF PARENT COMMON SHARES. The Parent covenants that if any
Parent Common Shares to be issued and delivered pursuant to the Exchange Right
or the Automatic Exchange Rights require registration or qualification with or
approval of or the filing of any document including any prospectus or similar
document or the taking of any proceeding with or the obtaining of any order,
mailing or consent from any governmental or regulatory authority under any
Canadian or United States federal, provincial or state law or regulation or
pursuant to the rules and regulations of any regulatory authority or the
fulfillment of any other legal requirement before such shares may be issued and
delivered by the Parent to the initial bolder thereof or in order that such
shares may be freely traded thereafter (other than any restrictions on transfer
by reason of a holder being a "control person of the Parent for purposes of
Canadian federal or provincial securities law or an "affiliate" of the Parent
for purposes of United States federal or state securities law), the Parent will
in good faith expeditiously take all such actions and do all such things as are
necessary or desirable to cause such Parent Common Shares to be and remain duly
registered, qualified or approved. The Parent will in good faith expeditiously
take all such actions and do all such things as are necessary or desirable to
cause all Parent Common Shares to be delivered pursuant to the Exchange Right or
the Automatic Exchange Rights to be listed, quoted or posted for trading on all
stock exchanges and quotation systems on which outstanding Parent Common Shares
are listed, quoted or posted for trading at such time.

5.11   RESERVATION OF PARENT COMMON SHARES.

       The Parent 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 Parent Common 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 to meet its
obligations hereunder, under the Support Agreement, under the Exchangeable Share
Provisions and under any other security or commitment pursuant to which the
Parent may now or hereafter be required to issue Parent Common Shares.

5.12   AUTOMATIC EXCHANGE ON LIQUIDATION OF PARENT.

       (a)   The Parent will give the Trustee notice of each of the following
             events at the time set forth below:



                                      -17-

<PAGE>   18

             (i)   in the event of any determination by the Board of Directors
                   of the Parent to institute voluntary liquidation, dissolution
                   or winding-up proceedings with respect to the Parent or to
                   effect any other distribution of assets of the Parent 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 the Parent of
                   notice of and (B) the Parent 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 the Parent or to effect any
                   other distribution of assets of the Parent among its
                   shareholders for the purpose of winding up its affairs.

       (b)   Immediately following receipt by the Trustee from the Parent 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
             Parent Common 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 Parent Common Shares in the
             distribution of assets of the Parent in connection with a
             Liquidation Event, on the fifth Business Day prior to the effective
             date (the "Liquidation Event Effective Date") of a Liquidation
             Event all of the then outstanding Exchangeable Shares shall be
             automatically exchanged for Parent Common Share. To effect such
             automatic exchange, the Parent 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 share equal to (a) the Current
             Market Price of a Parent Common Share on the fifth Business Day
             prior to the Liquidation Event Effective Date, which shall be
             satisfied in lull by the Parent issuing to the Beneficiary one
             Parent Common Share, plus (b) an additional amount equivalent to
             the full amount of all dividends declared and unpaid thereon. In
             connection with such automatic exchange, the Parent will provide to
             the Trustee an Officer's Certificate setting forth the calculation
             of the purchase price for each Exchangeable Share.

       (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
             Parent Common Shares



                                      -18-

<PAGE>   19

             shall be deemed to have occurred, and each Beneficiary of
             Exchangeable Shares shall be deemed to have transferred to the
             Parent all of the Beneficiary's right, title and interest in and to
             such Exchangeable Shares and the related interest in the Trust
             Estate and shall cease to be a holder of such Exchangeable Shares
             and the Parent shall issue to the Beneficiary the Parent Common
             Shares issuable upon the automatic exchange of Exchangeable Shares
             for Parent Common 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 the Parent Common Shares issued to it
             pursuant to the automatic exchange of Exchangeable Shares for
             Parent Common Shares and the certificates held by the Beneficiary
             previously representing the Exchangeable Shares exchanged by the
             Beneficiary with the Parent pursuant to such automatic exchange
             shall thereafter be deemed to represent the Parent Common Shares
             issued to the Beneficiary by the Parent pursuant to such automatic
             exchange. Upon the request of a Beneficiary and the surrender by
             the Beneficiary of Exchangeable Share certificates deemed to
             represent Parent Common Shares, duly endorsed in blank and
             accompanied by such instruments of transfer as the Parent may
             reasonably require, the Parent shall deliver or cause to be
             delivered to the Beneficiary certificates representing the Parent
             Common Shares of which the Beneficiary is the holder.

                             CONCERNING THE TRUSTEE

7.1    POWERS AND DUTIES OF THE TRUSTEE. The rights, powers and authorities of
the Trustee under this trust agreement, in its capacity as trustee of the Trust,
shall include:

       (a)   purchasing the Voting Share from the Parent 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 trust agreement;

       (c)   voting the Beneficiary Votes in accordance with the provisions of
             this trust agreement;

       (d)   receiving the grant of the Exchange Right and the Automatic
             Exchange Rights from the Parent as trustee for and on behalf of the
             Beneficiaries in accordance with the provisions of this trust
             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 trust agreement, and in connection therewith
             receiving from Beneficiaries Exchangeable Shares and other
             requisite documents and distributing to such Beneficiaries the
             Parent Common 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 this trust agreement;

       (h)   taking action on its own initiative or at the direction of a
             Beneficiary or Beneficiaries to enforce the obligations of the
             Parent under this trust agreement; and

       (i)   taking such other actions and doing such other things as are
             specifically provided in this trust 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 trust agreement as
the Trustee, acting in good faith and in the reasonable exercise of its
discretion, may deem necessary, appropriate or



                                      -20-

<PAGE>   21


desirable to effect the purpose of the Trust. Any exercise of such discretionary
rights, powers and authorities by the Trustee shall be final, conclusive and
binding upon all persons. For greater certainty, the Trustee shall have only
those duties as are set out specifically in this trust agreement.

       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 trustee would exercise in comparable circumstances.

7.2    NO CONFLICT OF INTEREST. The Trustee represents to the Corporation and
the Parent that at the date of execution and delivery of this trust agreement
there exists no material conflict of interest in the role of the Trustee as a
fiduciary hereunder and the role of the Trustee 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. 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
trust 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

             binding on all such adverse claimants, and the Trustee shall have
             been furnished with an executed copy of such agreement.

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.

and severally agree to indemnify and hold harmless the Trustee and each of its

claims, losses, damages, costs, penalties, fines and reasonable expenses
(including reasonable expenses of the Trustee's legal counsel) which, without
fraud, negligence, willful misconduct or bad faith 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, its compliance with its duties set forth in this trust agreement, or any
written or oral instructions delivered to the Trustee by the Parent or the
Corporation pursuant hereto. In no case shall the Parent or the Corporation be
liable under this indemnity for any claim against any of the Indemnified Parties
unless the Parent 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, the Parent and the Corporation shall be entitled
to participate at their own expense in the defence and, if the Parent 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

Parent or the Corporation (in which case the Parent and the Corporation shall
not have the right to assume the defence of such suit on behalf of the Trustee
but shall be liable to pay the reasonable fees and expenses of counsel for the
Trustee).

of Exchangeable Shares which such holder has the right to receive (together with
any dividends or distributions with respect thereto pursuant to section 4.3 and

right to receive (together with any dividends or distributions with respect
thereto pursuant to section 4.3 and any cash in lieu of fractional SoftKey
International Common Shares pursuant to section 4.4), and the certificate so
surrendered shall forthwith be cancelled. No certificates representing Class A
Shares shall be issued to the holders of Elected SoftKey Common Shares which are
converted into Class A Shares. In the event of a transfer of ownership of
Elected SoftKey Common Shares which is not registered in the transfer records of
SoftKey, a certificate representing the proper number of SoftKey International
Common Shares may be issued to a transferee if the certificate representing such

unsurrendered certificate which immediately prior to the Effective Time
represented outstanding SoftKey Common Shares that were converted or exchanged
pursuant to section 2.1, and no cash payment in lieu of fractional shares shall
be paid to any such holder pursuant to section 4.4, unless and until the holder

surrender of any such certificate, there shall be paid to the record holder of
the certificates representing whole Exchangeable Shares or SoftKey International
Common Shares, as the case may be, without interest (i) the amount of any cash
payable in lieu of a fractional Exchangeable Share or SoftKey International
Common Share to which such holder is entitled pursuant to section 4.4, (ii) the
amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole Exchangeable Share or
SoftKey International Common Share, as the case may be, and (iii) at the

4.4    NO FRACTIONAL SHARES

       No certificates or scrip representing fractional Exchangeable Shares or
SoftKey International Common Shares shall be issued upon the surrender for
exchange of certificates pursuant to section 4.1 or section 4.2 and, subject to
the last sentence of this section 4.4, no dividend, stock split or other change
in the capital structure of the Corporation or SoftKey International shall
relate to any such fractional security and such fractional interests shall not
entitle the owner thereof to vote or to exercise any rights as a security holder
of the Corporation or SoftKey International. In lieu of any such fractional
securities:

       (a)   each person entitled to a fractional interest in an Exchangeable
             Share will receive a cash payment equal to such person's pro rata
             portion of the net proceeds after expenses received by the
             Depositary upon the sale of whole shares representing an
             accumulation of all fractional interests in Exchangeable Shares to
             which all such persons would otherwise be entitled. The Depositary
             will sell the Exchangeable Shares involved on The Toronto Stock
             Exchange as soon as practicable following the



                                      -10-

<PAGE>   11


             Effective Date. The aggregate net proceeds after expenses of such
             sale will be distributed by the Depositary, pro rata in relation to
             the respective fractions, among the persons otherwise entitled to
             receive fractional interests in Exchangeable Shares; and

       (b)   each person entitled to a fractional interest in a SoftKey
             International Common Share will receive a cash payment equal to
             such person's pro rata portion of the net proceeds after expenses
             received by the Depositary upon the sale of whole shares
             representing an accumulation of all fractional interests in SoftKey
             International Common Shares to which all such persons would
             otherwise be entitled. The Depositary will sell the SoftKey
             International Common Shares involved on NASDAQ as soon as
             practicable following the Effective Date. The aggregate net
             proceeds after expenses of such sale will be distributed by the
             Depositary, pro rata in relation to the respective fractions, among
             the persons otherwise entitled to receive fractional interests in
             SoftKey International Common Shares.

The determination as to whether any former holder of Class A Shares would, apart
from this section 4.4, be entitled to receive a fractional interest in a SoftKey
International Common Share shall be made once only, after taking into account
the SoftKey International Consolidation ff the SoftKey International
Consolidation shall become effective, and the determination as to whether any
former holder of Class B Shares would, apart from this section 4.4, be entitled
to receive a fractional interest in an Exchangeable Share shall be made once
only, after taking into account the SoftKey International Consolidation if the
SoftKey International Consolidation shall become effective.

4.5    LOST CERTIFICATES

       In the event any certificate which immediately prior to the Effective
Time represented outstanding SoftKey Common Shares that were converted or
exchanged pursuant to section 2.1 shall have been lost, stolen or destroyed,
upon the making of an affidavit of that fact by the person claiming such
certificate to be lost, stolen or destroyed, the Depositary will issue in
exchange for such lost, stolen or destroyed certificate, certificates
representing Exchangeable Shares or SoftKey International Common Shares (and any
dividends or distributions with respect thereto and any cash pursuant to section
4.4) deliverable in respect thereof as determined in accordance with section
2.1. When authorizing such payment in exchange for any lost, stolen or destroyed
certificate, the person to whom certificates representing Exchangeable Shares or
SoftKey International Common Shares are to be issued shall, as a condition
precedent to the issuance thereof, give a bond satisfactory to the Corporation
or SoftKey International, as the case may be, in such sum as the Corporation or
SoftKey International may direct or otherwise indemnify the





                                      -11-


<PAGE>   12


Corporation or SoftKey International in a manner satisfactory to the Corporation
or SoftKey International against any claim that may be made against the
Corporation or SoftKey International with respect to the certificate alleged to
have been lost, stolen or destroyed.

4.6    EXTINGUISHMENT OF RIGHTS

       Any certificate which immediately prior to the Effective Time represented
outstanding SoftKey Common Shares that were converted or exchanged pursuant to
section 2.1 and not deposited, with all other instruments required by section
4.1 or section 42, on or prior to the tenth anniversary of the Effective Date
shall cease to represent a claim or interest of any kind or nature as a
shareholder of SoftKey, the Corporation or SoftKey International. On such date,
the Exchangeable Shares or SoftKey International Common Shares to which the
former registered holder of the certificate referred to in the preceding
sentence was ultimately entitled shall be deemed to have been surrendered to the
Corporation or SoftKey International, as the case may be, together with all
entitlements to dividends, distributions and interests thereon held for such
former registered holder.

                          ARTICLE 5 - CERTAIN RIGHTS OF
              SOFTKEY INTERNATIONAL TO ACQUIRE EXCHANGEABLE SHARES

5.1    SOFTKEY INTERNATIONAL LIQUIDATION CALL RIGHT

       (a)   SoftKey International shall have the overriding right (the
"Liquidation Call Right"), in the event of and notwithstanding the proposed
liquidation, dissolution or winding-up of the Corporation pursuant to Article 5
of the Exchangeable Share Provisions, to purchase from all but not less than all
of the holders of Exchangeable Shares on the Liquidation Date all but not less
than all of the Exchangeable Shares held by each such holder on payment by
SoftKey International of an amount per share equal to (a) the Current Market
Price (as defined in the Exchangeable Share Provisions) of a SoftKey
International Common 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 SoftKey International Common Share, plus (b) an additional amount equivalent
to the full amount of all dividends declared and unpaid on such Exchangeable
Share (collectively the "Liquidation Call Purchase Price"). In the event of the
exercise of the Liquidation Call Right by SoftKey International, each holder
shall be obligated to sell all the Exchangeable Shares held by the holder to
SoftKey International on the Liquidation Date on payment by SoftKey
International to the holder of the Liquidation Call Purchase Price for each such
share.

       (b)   To exercise the Liquidation Call Right, SoftKey International must
notify the Corporation's transfer agent (the "Transfer Agent"), as agent for the
holders of Exchangeable Shares, and the Corporation of SoftKey International's
intention to



                                      -12-

<PAGE>   13



exercise such right at least 55 days before the Liquidation Date in the case of
a voluntary liquidation, dissolution or winding up of the Corporation and at
least five Business Days before the Liquidation Date in the case of an
involuntary liquidation, dissolution or winding up of the Corporation. The
Transfer Agent will notify the holders of Exchangeable Shares as to whether or
not SoftKey International has exercised the Liquidation Call Right forthwith
after the expiry of the period during which the same may be exercised by SoftKey
International. If SoftKey International exercises the Liquidation Call Right, on
the Liquidation Date SoftKey International will purchase and the holders will
sell all of the Exchangeable Shares then outstanding for a price per 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, SoftKey International shall
deposit with the Transfer Agent, on or before the Liquidation Date, certificates
representing the aggregate number of SoftKey International Common Shares
deliverable by SoftKey International 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,
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 SoftKey International 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 SoftKey International Common 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 OBCA and the by-laws of the
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 SoftKey International shall deliver to such holder,
certificates representing the SoftKey International Common Shares to which the
holder is entitled and a cheque or cheques of SoftKey International payable at
par and in Canadian dollars at any branch of the bankers of SoftKey
International or of the Corporation in Canada in payment of the remaining
portion, if any, of the total Liquidation Call Purchase Price. If SoftKey
International 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 Corporation in connection with the liquidation, dissolution or
winding-up of the Corporation pursuant to Article 5 of the Exchangeable Share
Provisions.

<PAGE>   14


5.2    SOFTKEY INTERNATIONAL REDEMPTION CALL RIGHT

       (a)   SoftKey International shall have the overriding right (the
"Redemption Call Right"), notwithstanding the proposed redemption of the
Exchangeable Shares by the 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 on the Automatic Redemption Date all but not less than all
of the Exchangeable Shares held by each such holder on payment by SoftKey
International to the holder of an amount per share equal to (a) the Current
Market Price (as defined in the Exchangeable Share Provisions) of a SoftKey
International Common Share on the last Business Day prior to the Automatic
Redemption Date which shall be satisfied in full by causing to be delivered to
such holder one SoftKey International Common Share plus (b) an additional amount
equivalent to the full amount of all dividends declared and unpaid on such
Exchangeable Share (collectively the "Redemption Call Purchase Price"). In the
event of the exercise of the Redemption Call Right by SoftKey International,
each holder shall be obligated to sell all the Exchangeable Shares held by the
holder to SoftKey International on the Automatic Redemption Date on payment by
SoftKey International to the holder of the Redemption Call Purchase Price for
each such share.

       (b)   To exercise the Redemption Call Right, SoftKey International must
notify the Transfer Agent, as agent for the holders of Exchangeable Shares, and
the Corporation of SoftKey International's intention to exercise such right at
least 125 days before the Automatic Redemption Date. The Transfer Agent will
notify the holders of the Exchangeable Shares as to whether or not SoftKey
International has exercised the Redemption Call Right forthwith after the expiry
of the period during which the same may be exercised by SoftKey International.
If SoftKey International exercises the Redemption Call Right, on the Automatic
Redemption Date SoftKey International will purchase and the holders will sell
all of the Exchangeable Shares then outstanding for a price per share equal to
the Redemption Call Purchase Price.

       (c)   For the purposes of completing the purchase of the Exchangeable
Shares pursuant to the Redemption Call Right, SoftKey International shall
deposit with the Transfer Agent, on or before the Automatic Redemption Date,
certificates representing the aggregate number of SoftKey International Common
Shares deliverable by SoftKey International 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 Automatic Redemption Date the rights of each holder of
Exchangeable Shares will be limited to receiving such holder's proportionate
part of the total Redemption Call Purchase Price payable by SoftKey
International 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 SoftKey International Common Shares delivered



                                      -14-

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 OBCA and the by-laws of the 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
SoftKey International shall deliver to such holder, certificates representing
the SoftKey International Common Shares to which the holder is entitled and a
cheque or cheques of SoftKey International payable at par and in Canadian
dollars at any branch of the bankers of SoftKey International or of the
Corporation in Canada in payment of the remaining portion, if any, of the total
Redemption Call Purchase Price. If SoftKey International does not exercise the
Redemption Call Right in the manner described above, on the Automatic Redemption
Date the holders of the Exchangeable Shares will be entitled to receive in
exchange therefor for the redemption price otherwise payable by the Corporation
in connection with the redemption of the Exchangeable Shares pursuant to
Article 7 of the Exchangeable Share Provisions.

                              CERTAIN RESTRICTIONS

             Convertible Debentures of the Corporation or as contemplated by the
             Support Agreement.

The restrictions in Sections 4.1(a), 4.1(b) and 4.1(c) above shall not apply if
all dividends on the outstanding Exchangeable Shares corresponding to dividends
declared to date on the SoftKey International Common Shares shall have been
declared on the Exchangeable Shares and paid in full.

                                    ARTICLE 5
                           DISTRIBUTION ON LIQUIDATION

5.1    In the event of the liquidation, dissolution or winding-up of the
Corporation or any other distribution of the assets of the Corporation among its

Shares shall be entitled, subject to applicable law, to receive from the assets
of the Corporation in respect of each Exchangeable Share held by such holder on
the effective date (the "Liquidation Date") of such liquidation, dissolution or
winding-up, before any distribution of any part of the assets of the Corporation

ranking junior to the Exchangeable Shares, an amount per share equal to (a) the
Current Market Price of a SoftKey International Common Share on the last

<PAGE>   24



Corporation causing to be delivered to such holder one SoftKey International
Common Share, plus (b) an additional amount equivalent to the full amount of all
declared and unpaid dividends on each such Exchangeable Share (collectively the
"Liquidation Amount").

5.2    On or promptly after the Liquidation Date, and subject to the exercise by
SoftKey International of the Liquidation Call Right, the Corporation shall cause
to be delivered to the holders of the Exchangeable Shares the Liquidation Amount
for each such Exchangeable Share upon presentation and surrender of the
certificates representing such Exchangeable Shares, together with such other
documents and instruments as may be required to effect a transfer of
Exchangeable Shares under the Business Corporations Act (Ontario) and the
by-laws of the Corporation and such additional documents and instruments as the
Transfer Agent may reasonably require, at the registered office of the
Corporation or at any office of the Transfer Agent as may be specified by the
Corporation by notice to the holders of the Exchangeable Shares. Payment of the
total Liquidation Amount for such Exchangeable Shares shall be made by delivery
to each holder, at the address of the holder recorded in the securities register
of the Corporation for the Exchangeable Shares or by holding for pick up by the
holder at the registered office of the Corporation or at any office of the
Transfer Agent as may be specified by the Corporation by notice to the holders
of Exchangeable Shares, on behalf of the Corporation of certificates
representing SoftKey International Common Shares (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 a cheque of the Corporation payable at par at any
branch of the bankers of the Corporation in respect of the amount equivalent to
the full amount of all declared and unpaid dividends comprising part of the
total Liquidation Amount (less any tax required to be deducted and withheld
therefrom by the Corporation). On and after the Liquidation Date, the holders of
the Exchangeable Shares shall cease to be holders of such Exchangeable Shares
and shall not be entitled to exercise any of the rights of holders in respect
thereof, other than the right to receive their proportionate part of the total
Liquidation Amount, unless payment of the total Liquidation Amount for such
Exchangeable Shares shall not be made upon presentation and surrender of share
certificates in accordance with the foregoing provisions, in which case the
rights of the holders shall remain unaffected until the total Liquidation Amount
has been paid in the manner hereinbefore provided. The Corporation shall have
the right at any time after the Liquidation Date to deposit or cause to be
deposited the total Liquidation Amount in respect of the Exchangeable Shares
represented by certificates that have not at the Liquidation Date been
surrendered by the holders thereof in a custodial account with any chartered
bank or trust company in Canada. Upon such deposit being made, the rights of the
holders of Exchangeable Shares after such deposit shall be limited to receiving
their proportionate part of the total Liquidation Amount (less any tax required
to be deducted and withheld therefrom) for such Exchangeable Shares so
deposited, against presentation and surrender of the said certificates held by
them, respectively, in accordance with the foregoing provisions. Upon such
payment or deposit of the total Liquidation Amount, the holders of the
Exchangeable Shares shall





                                      -9-

<PAGE>   25


thereafter be considered and deemed for all purposes to be the holders of the
SoftKey International Common Shares delivered to them.

5.3    After the Corporation has satisfied its obligations to pay the holders of
the Exchangeable Shares the Liquidation Amount per Exchangeable Share pursuant
to Section 5.1 of these share provisions, such holders shall not be entitled to
share in any further distribution of the assets of the Corporation.

                                    ARTICLE 6
                   RETRACTION OF EXCHANGEABLE SHARES BY HOLDER

6.1    A holder of Exchangeable Shares shall be entitled at any time, subject to
the exercise by SoftKey International of the Retraction Call Right and otherwise

Corporation to redeem any or all of the Exchangeable Shares registered in the
name of such holder for an amount per share equal to (a) the Current Market
Price of a SoftKey International Common Share on the last Business Day prior to
the Retraction Date, which shall be satisfied in full by the Corporation causing
to be delivered to such holder one SoftKey International Common Share for each
Exchangeable Share presented and surrendered by the holder, plus (b) an
additional amount equivalent to the full amount of all dividends declared and
unpaid thereon (collectively the "Retraction Price," provided that if the record
date for any such declared and unpaid dividends occurs on or after the
Retraction Date the Retraction Price shall not include such additional amount
equivalent to the declared and unpaid dividends). To effect such redemption, the
holder shall present and surrender at the registered office of the Corporation
or at any office of the Transfer Agent as may be specified by the Corporation by
notice to the holders of Exchangeable Shares the certificate or certificates
representing the Exchangeable Shares which the holder desires to have the
Corporation redeem, together with such other documents and instruments as may be
required to effect a transfer of Exchangeable Shares under the Business
Corporations Act (Ontario) and the by-laws of the Corporation and such
additional documents and instruments as the Transfer Agent may reasonably
require, and together with a duly executed statement (the "Retraction Request")
in the form of Schedule A hereto or in such other form as may be acceptable to
the Corporation:

       (a)   specifying that the holder desires to have all or any number
             specified therein of the Exchangeable Shares represented by such
             certificate or certificates (the "Retracted Shares") redeemed by
             the Corporation;

       (b)   stating the Business Day on which the holder desires to have the
             Corporation redeem the Retracted Shares (the "Retraction Date"),
             provided that the Retraction Date shall be not less than five
             Business Days nor more than ten Business Days after the date on
             which the Retraction Request is received by the Corporation and
             further provided that, in the event that no




                                      -10-

<PAGE>   26


             such Business Day is specified by the holder in the Retraction
             Request, the Retraction Date shall be deemed to be the tenth
             Business Day after the date on which the Retraction Request is
             received by the Corporation; and

       (c)   acknowledging the overriding right (the "Retraction Call Right") of
             SoftKey International to purchase all but not less than all the
             Retracted Shares directly from the holder and that the Retraction
             Request shall be deemed to be a revocable offer by the holder to
             sell the Retracted Shares to SoftKey International in accordance
             with the Retraction Call Right on the terms and conditions set out
             in Section 6.3 below.

6.2    Subject to the exercise by SoftKey International of the Retraction Call
Right, upon receipt by the Corporation or the Transfer Agent in the manner
specified in Section 6.1 hereof of a certificate or certificates representing
the number of Exchangeable Shares which the holder desires to have the
Corporation redeem, together with a Retraction Request, and provided that the
Retraction Request is not revoked by the holder in the manner specified in
Section 6.7, the Corporation shall redeem the Retracted Shares effective at the
close of business on the Retraction Date and shall cause to be delivered to such
holder the total Retraction Price with respect to such shares. If only a part of
the Exchangeable Shares represented by any certificate are redeemed (or
purchased by SoftKey International pursuant to the Retraction Call Right), a new
certificate for the balance of such Exchangeable Shares shall be issued to the
holder at the expense of the Corporation.

6.3    Upon receipt by the Corporation of a Retraction Request, the Corporation
shall immediately notify SoftKey International thereof. In order to exercise the
Retraction Call Right, SoftKey International must notify the Corporation in
writing of its determination to do so (the "SoftKey International Call Notice")
within two Business Days of notification to SoftKey International by the
Corporation of the receipt by the Corporation of the Retraction Request. If
SoftKey International does not so notify the Corporation within such two
Business Day period, the Corporation will notify the holder as soon as possible
thereafter that SoftKey International will not exercise the Retraction Call
Right. If SoftKey International delivers the SoftKey International Call Notice
within such two Business Day time period, and provided that the Retraction
Request is not revoked by the holder in the manner specified in Section 6.7, the
Retraction Request shall thereupon be considered only to be an offer by the
holder to sell the Retracted Shares to SoftKey International in accordance with
the Retraction Call Right. In such event, the Corporation shall not redeem the
Retracted Shares and SoftKey International shall purchase from such holder and
such holder shall sell to SoftKey International on the Retraction Date the
Retracted Shares for a purchase price (the "Purchase Price") per share equal to
the Retraction Price per share. For the purposes of completing a purchase
pursuant to the Retraction Call Right, SoftKey International shall deposit with
the Transfer Agent, on or before the Retraction Date, certificates representing
SoftKey International Common Shares and a cheque in the amount of the remaining
portion, if





                                      -11-

<PAGE>   27



any, of the total Purchase Price. Provided that the total Purchase Price has
been so deposited with the Transfer Agent, the closing of the purchase and sale
of the Retracted Shares pursuant to the Retraction Call Right shall be deemed to
have occurred as at the close of business on the Retraction Date and, for
greater certainty, no redemption by the Corporation of such Retracted Shares
shall take place on the Retraction Date. In the event that SoftKey International
does not deliver a SoftKey International Call Notice within such two Business
Day period, and provided that Retraction Request is not revoked by the holder in
the manner specified in Section 6.7, the Corporation shall redeem the Retracted
Shares on the Retraction Date and in the manner otherwise contemplated in this
Article 6.

6.4    The Corporation or SoftKey International, as the case may be, shall
deliver or cause the Transfer Agent to deliver to the relevant holder, at the
address of the holder recorded in the securities register of the Corporation for
the Exchangeable Shares or at the address specified in the holder's Retraction
Request or by holding for pick up by the holder at the registered office of the
Corporation or at any office of the Transfer Agent as may be specified by the
Corporation by notice to the holders of Exchangeable Shares, certificates
representing the SoftKey International Common Shares (which shares shall be duly
issued as fully paid and non-assessable and shall be free and clear of any lien,
claim or encumbrance) registered in the name of the holder or in such other name
as the holder may request in payment of the total Retraction Price or the total
Purchase Price, as the case may be, and a cheque of the Corporation payable at
par at any branch of the bankers of the Corporation in payment of the remaining
portion, if any, of the total Retraction Price (less any tax required to be
deducted and withheld therefrom by the Corporation) or a cheque of SoftKey
International payable at par and in Canadian dollars at any branch of the
bankers of SoftKey International or of the Corporation in Canada in payment of
the remaining portion, if any, of the total Purchase Price, as the case may be,
and such delivery of such certificates and cheque on behalf of the Corporation
or by SoftKey International, as the case may be, or by the Transfer Agent shall
be deemed to be payment of and shall satisfy and discharge all liability for the
total Retraction Price or total Purchase Price, as the case may be, to the
extent that the same is represented by such share certificates and cheque (plus
any tax required and in fact deducted and withheld therefrom and remitted to the
proper tax authority), unless such cheque is not paid on due presentation.

6.5    On and after the close of business on the Retraction Date, the holder of
the Retracted Shares shall cease to be a holder of such Retracted 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
Retraction Price or total Purchase Price, as the case may be, unless upon
presentation and surrender of certificates in accordance with the foregoing
provisions, payment of the total Retraction Price or the total Purchase Price,
as the case may be, shall not be made, in which case the rights of such holder
shall remain unaffected until the total Retraction Price or the total Purchase
Price, as the case may be, has been paid in the manner hereinbefore provided. On
and after the close of

business on the Retraction Date, provided that presentation and surrender of
certificates and payment of the total Retraction Price or the total Purchase
Price, as the case may be, has been made in accordance with the foregoing
provisions, the holder of the Retracted Shares so redeemed by the Corporation or
purchased by SoftKey International shall thereafter be considered and deemed for
all purposes to be a holder of the SoftKey International Common Shares delivered
to it.

6.6    Notwithstanding any other provision of this Article 6, the Corporation
shall not be obligated to redeem Retracted Shares specified by a holder in a
Retraction Request to the extent that such redemption of Retracted Shares would
be contrary to solvency requirements or other provisions of applicable law. If
the Corporation believes that on any Retraction Date it would not be permitted
by any of such provisions to redeem the Retracted Shares tendered for redemption
on such date, and provided that SoftKey International shall not have exercised
the Retraction Call Right with respect to the Retracted Shares, the Corporation
shall only be obligated to redeem Retracted Shares specified by a holder in a
Retraction Request to the extent of the maximum number that may be so redeemed
(rounded down to a whole number of shares) as would not be contrary to such
provisions and shall notify the holder at least two Business Days prior to the
Retraction Date as to the number of Retracted Shares which will not be redeemed
by the Corporation. In any case in which the redemption by the Corporation of
Retracted Shares would be contrary to solvency requirements or other provisions
of applicable law, the Corporation shall redeem Retracted Shares in accordance
with Section 6.2 of these share provisions on a pro rata basis and shall issue
to each holder of Retracted Shares a new certificate, at the expense of the
Corporation, representing the Retracted Shares not redeemed by the Corporation
pursuant to Section 6.2 hereof. Provided that the Retraction Request is not
revoked by the holder in the manner specified in Section 6.7, the holder of any
such Retracted Shares not redeemed by the Corporation pursuant to Section 6.2 of
these share provisions as a result of solvency requirements of applicable law
shall be deemed by giving the Retraction Request to require SoftKey
International to purchase such Retracted Shares from such holder on the
Retraction Date or as soon as practicable thereafter on payment by SoftKey
International to such holder of the Purchase Price for each such Retracted
Share, all as more specifically provided in the Voting and Exchange Trust
Agreement.

6.7    A holder of Retracted Shares may, by notice in writing given by the
holder to the Corporation before the close of business on the Business Day
immediately preceding the Retraction Date, withdraw its Retraction Request in
which event such Retraction Request shall be null and void and, for greater
certainty, the revocable offer constituted by the Retraction Request to sell the
Retracted Shares to SoftKey International shall be deemed to have been revoked.

                                    ARTICLE 7
              REDEMPTION OF EXCHANGEABLE SHARES BY THE CORPORATION

7.1    Subject to applicable law, and subject to he exercise by SoftKey
International of the Redemption Call Right, the Corporation shall on the
Automatic Redemption Date redeem the whole of the then outstanding Exchangeable
Shares for an amount per share equal to (a) the Current Market Price of a
SoftKey International Common Share on the last Business Day prior to the
Automatic Redemption Date, which shall be satisfied in full by the Corporation
causing to be delivered to each holder of Exchangeable Shares one SoftKey
International Common Share for each Exchangeable Share held by such holder, plus
(b) an additional amount equivalent to the full amount of all declared and
unpaid dividends thereon (collectively the "Redemption Price").

7.2    In any case of a redemption of Exchangeable Shares under this Article 7,
the Corporation shall, at least 120 days before the Automatic Redemption Date,
send or cause to be sent to each holder of Exchangeable Shares a notice in
writing of the redemption by the Corporation or the purchase by SoftKey
International under the Redemption Call Right, as the case may be, of the
Exchangeable Shares held by such holder. Such notice shall set out the formula
for determining the Redemption Price or the Redemption Call Purchase Price, as
the case may be, the Automatic Redemption Date and, if applicable, particulars
of the Redemption Call Right. On or after the Automatic Redemption Date and
subject to the exercise by SoftKey International of the Redemption Call Right,
the Corporation shall cause to be delivered to the holders of the Exchangeable
Shares to be redeemed the Redemption Price for each such Exchangeable Share upon
presentation and surrender at the registered office of the Corporation or at any
office of the Transfer Agent as may be specified by the Corporation in such
notice of the certificates representing such Exchangeable Shares, together with
such other documents and instruments as may be required to effect a transfer of
Exchangeable Shares under the Business Corporations Act (Ontario) and the
by-laws of the Corporation and such additional documents and instruments as the
Transfer Agent may reasonably require. Payment of the total Redemption Price for
such Exchangeable Shares shall be made by delivery to each holder, at the
address of the holder recorded in the securities register of the Corporation or
by holding for pick up by the holder at the registered office of the Corporation
or at any office of the Transfer Agent as may be specified by the Corporation in
such notice, on behalf of the Corporation of certificates representing SoftKey
International Common Shares (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 a cheque of the Corporation payable at par at any branch of the bankers of
the Corporation in respect of the additional amount equivalent to the full
amount of all declared and unpaid dividends comprising part of the total
Redemption Price. On and after the Automatic Redemption Date, the holders of the
Exchangeable Shares called for redemption shall cease to be holders of such
Exchangeable Shares and shall not be entitled to exercise any of the rights of
holders in respect thereof, other than the right to receive their proportionate
part of the total Redemption Price, unless payment of the




                                      -14-

<PAGE>   30



total Redemption Price for such Exchangeable Shares shall not be made upon
presentation and surrender of certificates in accordance with the foregoing
provisions, in which case the rights of the holders shall remain unaffected
until the total Redemption Price has been paid in the manner hereinbefore
provided. The Corporation shall have the right at any time after the sending of
notice of its intention to redeem the Exchangeable Shares as aforesaid to
deposit or cause to be deposited the total Redemption Price of the Exchangeable
Shares so called for redemption, or of such of the said Exchangeable Shares
represented by certificates that have not at the date of such deposit been
surrendered by the holders thereof in connection with such redemption, in a
custodial account with any chartered bank or trust company in Canada named in
such notice. Upon the later of such deposit being made and the Automatic
Redemption Date, the Exchangeable Shares in respect whereof such deposit shall
have been made shall be redeemed and the rights of the holders thereof after
such deposit or Automatic Redemption Date, as the case may be, shall be limited
to receiving their proportionate part of the total Redemption Price for such
Exchangeable Shares so deposited, against presentation and surrender of the said
certificates held by them, respectively, in accordance with the foregoing
provisions. Upon such payment or deposit of the total Redemption Price, the
holders of the Exchangeable Shares shall thereafter be considered and deemed for
all purposes to be holders of the SoftKey International Common Shares delivered
to them.

                                    ARTICLE 8
                            PURCHASE FOR CANCELLATION

8.1    Subject to applicable law and the articles of the Corporation, the
Corporation may at any time and from time to time purchase for cancellation all
or any part of the outstanding Exchangeable Shares at any price by tender to all
the holders of record of Exchangeable Shares then outstanding or through the
facilities of any stock exchange on which the Exchangeable Shares are listed or
quoted at any price per share together with an amount equal to all declared and
unpaid dividends thereon. If in response to an invitation for tenders under the
provisions of this Section 8.1, more Exchangeable Shares are tendered at a price
or prices acceptable to the Corporation than the Corporation is prepared to
purchase, the Exchangeable Shares to be purchased by the Corporation shall be
purchased as nearly as may be pro rata according to the number of shares
tendered by each holder who submits a tender to the Corporation, provided that
when shares are tendered at different prices, the pro rating shall be effected
(disregarding fractions) only with respect to the shares tendered at the price
at which more shares were tendered than the Corporation is prepared to purchase
after the Corporation has purchased all the shares tendered at lower prices. If
only part of the Exchangeable Shares represented by any certificate shall be
purchased, a new certificate for the balance of such shares shall be issued at
the expense of the Corporation.

change or remove any right, privilege, restriction or condition attaching to the
Exchangeable Shares or any other matter requiring the approval or consent of the

minimum requirement that such approval be evidenced by resolution passed by not
less than two-thirds of the votes cast on such resolution at a meeting of
holders of Exchangeable Shares duly called and held at which the holders of at
least 50% of the outstanding Exchangeable Shares at that time are present or
represented by proxy; provided that if at any such meeting the holders of at
least 50% of the outstanding Exchangeable Shares at that time are not present or
represented by proxy within one-half hour after the time appointed for such
meeting then the meeting shall be adjourned to such date not less than 10 days

                              NOTICE OF RETRACTION

To the Corporation and SoftKey International Inc.

     This notice is given pursuant to Article 6 of the provisions (the "Share
Provisions") attaching to the share(s) represented by this certificate and all
capitalized words and expressions used in this notice which are defined in the
Share Provisions have the meanings ascribed to such words and expressions in
such Share Provisions.

     The undersigned hereby notifies the Corporation that, subject to the
Retraction Call Right referred to below, the undersigned desires to have the
Corporation redeem in accordance with Article 6 of the Share Provisions:

[ ] ______________ share(s) only.

     The undersigned hereby notifies the Corporation that the Retraction Date
shall be _______________________.

NOTE: The Retraction Date must be a Business Day and must not be less than five
      Business Days nor more than 10 Business Days after the date upon which
      this notice is received by the Corporation. In the event that no such
      Business Day is specified above, the Retraction Date shall be deemed to be
      the tenth Business Day after the date on which this notice is received by
      the Corporation.

     The undersigned acknowledges the Retraction Call Right of SoftKey
International to purchase all but not less than all the Retracted Shares from

to purchase the unredeemed Retracted Shares.

     The undersigned hereby represents and warrants to the Corporation and
SoftKey International that the undersigned has good title to, and owns, the

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

Ladies and Gentlemen:

   
     We have acted as counsel to The Learning Company, Inc. (the "Company") in
connection with the Registration Statement on Form S-3, as amended (the
"Registration Statement"), relating to the shares of Common Stock issuable to
the holders of New Exchangeable Shares pursuant to the terms of the New
Exchangeable Shares. Unless otherwise indicated, capitalized terms used herein
shall have the meaning ascribed to them in the prospectus included in the
Registration Statement (the "Prospectus"). We hereby confirm that, assuming that
shares of Common Stock are issued to holders of New Exchangeable Shares pursuant
to the terms of the New Exchangeable Shares as described in the Prospectus, the
discussion under the caption "INCOME TAX CONSEQUENCES - United States Federal
Tax Consequences" in the Prospectus expresses our opinion regarding the material
United States Federal tax consequences to holders of New Exchangeable Shares
that receive Common Stock in exchange for such New Exchangeable Shares pursuant
to their terms, and the ownership and disposition of Common Stock acquired in
the exchange.
    

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the caption "INCOME TAX
CONSEQUENCES - United States Federal Tax Consequences" in the Prospectus. In
giving this consent, we do not thereby admit that we are in the category of
persons whose consent is required under Section 7 of the Securities Act of 1933,
as amended.


                                        Very truly yours,

U.S.A. 02142

Ladies and Gentlemen:

                       REGISTRATION STATEMENT ON FORM S-3

   
     We have acted as counsel to SoftKey Software Products Inc. in connection
with the Registration Statement (the "Registration Statement") on Form S-3 filed
with the Securities and Exchange Commission (the "Commission") on November 19,
1997, as amended, for the purpose of registering 4,438,480 shares of common
stock, par value U.S.$0.01 per share, of The Learning Company, Inc.
    

     We have aided in the preparation of the Registration Statement, including,
in particular the discussion under the heading "INCOME TAX CONSIDERATIONS --
Canadian Federal Income Tax Considerations" (the "Tax Summary").

     We hereby confirm that, as of the date hereof, the Tax Summary is a fair
and accurate summary, in all material respects, of the matters addressed
therein, based upon the assumptions stated or referred to therein. It is
possible that contrary positions may be taken by Revenue Canada, Customs, Excise
& Taxation and that a court may agree with such contrary positions.

     This opinion is furnished to you solely for your benefit in connection with
the filing of the Registration Statement and, except as set forth below, is not
to be used, circulated, quoted or otherwise referred to for any other purpose or
relied upon by any other person for any purpose without our prior written
consent. We also consent to the use of our name in the Tax Summary and to the
filing of this opinion with the Commission as an exhibit to the Registration
Statement. In giving this consent, we do not thereby admit that we are within
the category of persons whose consent is required under Section 7 of the
SECURITIES ACT OF 1933, as amended, or the rules and regulations of the
Commission promulgated thereunder.



                                             Yours very truly,
   
                                             /s/ Davies, Ward & Beck
