                              PROSPECTUS SUMMARY

          The following summary does not purport to be complete and is
     qualified in its entirety by the more detailed information and
     consolidated financial statements and related notes incorporated by
     reference in this Prospectus.  The Securities and the Comptons
     Shares offered hereby involve a high degree of risk.  See "Risk
     Factors."

                                 THE COMPANY

          General.  SoftKey is a developer and publisher of high-quality
     consumer software for personal computers ("PCs"), primarily
     produced on CD-ROM.  The Company currently offers over 500 software
     titles in consumer-oriented categories, including education,
     lifestyle, edutainment, reference, productivity and, to a lesser
     extent, entertainment, in North America.  The Company distributes
     additional products internationally.  The Company's products
     include titles such as:  Calendar Creator Plus , Infopedia , Sports
     Illustrated  Swimsuit Calendar, Time Almanac, BodyWorks  4.0, The
     American Heritage  Talking Dictionary, Leonardo -- the Inventor ,
     PC Paintbrush , Key 3D Design Center  and Compton's Interactive
     Encyclopedia.  The Company also publishes lower priced boxed
     products under the "Key" brand and a line of jewel-case only
     products under the "Platinum" brand.  As a result of the Company's
     recent acquisition of The Learning Company, the Company added a
     number of educational products, classified into several product
     "families," to its offerings, including those in The Learning
     Company's "Rabbit" family (including the Reader Rabbit Series),
     "Treasure" family, "Super Solvers" family, "Writing Tools" family,
     "College Prep" family and "Foreign Languages" family.  The Company
     publishes school editions of a number of these products.

          SoftKey's objective is to be the leading worldwide producer of
     value-priced, high-quality consumer software.  Accordingly,
     SoftKey's strategy is to develop, license and acquire 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, including retail channels, direct mail, original
     equipment manufacturers ("OEMs") and school channels.  Key elements
     of this strategy include focusing on high-growth consumer software,
     broadly distributing to the consumer market at various price
     points, building strong relationships with retail channels,
     acquiring complementary products, technologies and businesses and
     enhancing brand awareness and customer loyalty.

          The Company was created through a combination of three
     corporations.  On February 4, 1994, the Company, which was then
     known as WordStar International Incorporated ("WordStar"),
     completed a three-way business combination transaction with SoftKey
     Software Products Inc. ("Former SoftKey") and Spinnaker Software
     Corporation ( Spinnaker ).  Effective February 4, 1994, the Company
     changed its name to SoftKey International Inc.

          Recent Acquisitions.  The Company has a history of acquiring
     companies in order to broaden its product lines and geographic
     sales channels.  In 1995, the Company's acquisitions included,
     among others, The Learning Company, a publisher of educational
     software, Compton's NewMedia, Inc. and Compton's Learning Company,
     publishers of educational software and encyclopedia products (two
     former wholly owned subsidiaries of Tribune Company), tewi Verlag
     GmbH, a German publisher and distributor of CD-ROM software and
     computer-related books ("tewi"), and Future Vision Holding, Inc., a
     multimedia software company ("Future Vision").

          Additionally, the Company has entered into a definitive merger
     agreement to acquire Minnesota Educational Computing Corporation
     (MECC) ("MECC"), a publisher and distributor of high quality
     educational software for children.  The closing of this transaction
     is subject to a number of conditions and approvals including the
     approval of the stockholders of MECC and the Company.  There can be
     no assurance that this transaction will be consummated.

          The Company's acquisition of The Learning Company and proposed
     acquisition of MECC, which together would make the Company the
     largest educational software company in the world, represent a new
     product-content focus for the Company's business in the education
     area.  The Company believes this new focus will likely result in,
     among other things, significant investments by the Company in
     product planning and research and development and a higher degree
     of product acceptance risk.  In order for the Company to sell a
     sufficient volume of products to offset the increased costs
     associated with the development of educational software products,
     the Company currently plans to continue its strategy of extending
     product lines by offering multiple titles at various price points
     (including by offering full-featured educational products in its
     Premium product line) based on a common source code and to further
     expand its existing distribution channels.

          The Company is incorporated in Delaware.  Its principal
     executive offices are located at One Athenaeum Street, Cambridge,
     Massachusetts 02142, and its telephone number is (617) 494-1200.
     "SoftKey" and all of the Company's logos and product names are
     trademarks of the Company.

     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.

          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 these areas
     include Microsoft Corporation, Mattel, Sony, The Walt Disney
     Company, Viacom, IBM/Eduquest, Fisher-Price, Jostens, Electronic
     Arts, Sierra On-Line, Inc., Davidson & Associates, Mindscape, GT
     Interactive Software, Edmark and Broderbund Software, Inc.  To the
     extent that competitors achieve a performance, price or
     distribution advantage, the Company could be adversely affected.
     Consolidation in the consumer software industry creates new, larger
     competitors.  For example, CC International Inc. recently announced
     proposed mergers with Sierra On-Line, Inc. and Davidson &
     Associates.  This increased consolidation of the consumer software
     market may impact future growth potential and performance.

          Microsoft Corporation is the dominant supplier of computer
     operating systems and frequently coordinates its operating system
     marketing efforts with those for its applications software.
     Competition in Microsoft's Windows application segment from major
     software publishers is intensifying, and "competitive upgrade"
     price discounting among the major firms is eroding the traditional
     pricing structures that had previously existed in the software
     industry.  Microsoft launched the Windows '95 operating system in
     1995.  As a result, the Company has embarked on a program to
     transition many of its titles to Windows '95 format.  In 1995,
     Microsoft Corporation announced that it was reducing the price of a
     number of its common titles from $69.95 to $49.95.  Competitive
     pressures have resulted in price reductions throughout the industry
     with the result that industry-wide operating margins are likely to
     be adversely affected.

          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.  In
     addition, a number of the Company's competitors, such as Davidson &
     Associates (through New Media Express) and GT Interactive Software,
     have attempted, with some success, to enter into exclusive software
     distribution arrangements with certain retail outlets.  If the
     occurrence of these exclusive arrangements increases and the
     Company is not able to offer a competing product line or
     arrangement, the Company's operating results may be negatively
     impacted.  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 will 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 Company's existing
     product categories and, in particular, the education and
     entertainment 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.

          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 has engaged in discussions with certain businesses in pursuit
     of possible transactions.  Certain of these businesses may be
     substantial in size as compared to the Company.  Except as
     otherwise disclosed in this Prospectus, there are currently no
     understandings, agreements or commitments with respect to any
     acquisition, business combination or strategic alliance.  Moreover,
     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.

     RISK OF NONPAYMENT

          The Company anticipates that internally generated cash flow
     will be sufficient to meet its operating expenses and to make
     payments of interest or dividends under the Notes or the Series C
     Preferred Stock, as the case may be.  There can be no assurance,
     however, that the Company will generate sufficient internal cash
     flow to cover all required interest payments on its indebtedness,
     including that under the Notes, or dividends on the Series C
     Preferred Stock.

          To the extent that the Notes are not exchanged for Series C
     Preferred Stock or converted into Common Stock prior to their
     maturity or that the Series C Preferred Stock is not converted into
     Common Stock prior to its redemption and the Company is unable to
     generate sufficient cash flow from operations to cover its
     outstanding obligations, the Company may be required to attempt to
     refinance all or a portion of its then outstanding indebtedness
     under the Notes or its obligations to redeem and pay dividends on
     the Series C Preferred Stock, to dispose of assets or to seek
     additional financing.  There can be no assurance, however, that any
     necessary refinancing, disposition of assets or additional
     financing will be available or be able to be consummated on
     commercially reasonable terms.

     MANAGEMENT OF GROWTH; INTEGRATION OF ACQUIRED BUSINESSES; KEY EMPLOYEES

          The Company is currently experiencing a period of
     exceptionally 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, the Company has recently
     completed the acquisition of The Learning Company, Compton's
     NewMedia and Compton's Learning Company and has entered into a
     definitive merger agreement with MECC.  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
     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

          SoftKey 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.

          In the past, the Company focused primarily on the
     productivity, lifestyle and edutainment product categories.  These
     product categories have a lower development cost and are not
     considered as "hit" driven as the high-end, 16-bit and 32-bit
     entertainment and games software category (including products
     offered on the Sega, Nintendo and 3DO platforms) and the high-end,
     PC-based CD-ROM game category.  Additionally, the high-end
     entertainment and games category requires higher development and
     marketing costs and a higher cost of goods sold than the Company's
     traditional software business, is dominated by a number of very
     large competitors and is subject to rapid change in consumer
     preference.  Should the Company substantially increase its presence
     in the high-end entertainment and games industry segment, it will
     experience these additional risks and competitive pressures.

          Similarly, the Company's new product-content focus and
     enhanced presence in the educational software market will require
     the Company to evaluate and adopt appropriate development and
     marketing strategies and methods, which may differ from those
     historically employed by the Company and subject the Company to the
     risks and competitive pressures associated with those new
     strategies.

          The Company's rights to license many 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 an arms-length
     negotiation on a case by case basis, and there is no general
     formula or industry standard for determining such fees.  Amounts
     typically paid by the Company for shelf space, cooperative
     advertising, promotional costs and market developments funds
     represent approximately 4-5% of gross sales.  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.

     SIGNIFICANT PRICE REDUCTIONS IN PERSONAL COMPUTER SOFTWARE

          Recently, several major publishers of PC software have
     significantly reduced the prices of their products with the goal of
     gaining greater market share, to the extent that at least one
     company (which is not a competitor of SoftKey) distributed its
     product at no cost (except what it represented as shipping and
     handling charges) in order to gain market share upon its entrance
     into a new market.  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 6, 1996 from sales occurring outside North
     America.  The Company's international revenues increased by 96% in
     1995 as compared to 1994.  This increase was driven by both the
     acquisition of tewi, a German company, on July 21, 1995 and
     increased penetration of personal computers in Europe, which in
     turn caused an increase in demand for and sales of consumer
     software products.  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 small 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 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,
     Stream International Inc., formerly known as the Global Software
     Services business unit of R.R. Donnelley & Sons Company ("Stream"),
     at facilities in Crawfordsville, Indiana.  Any interruption in
     Stream's manufacturing, assembly and fulfillment services could
     have a material adverse impact on the Company's business.  The
     Company's agreement with Stream expires in April 1997, and there
     can be no assurance that such agreement will be renewed or that the
     terms of any renewal will be the same as those currently in effect.
     Although the Company believes that suitable alternative suppliers
     exist, there can be no assurance that any termination or
     modification of the agreement with Stream 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, 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 $57,250,000
     for the year ended June 30, 1993 and $73,258,000 for the transition
     period from July 4, 1993 to January 1, 1994 and $65,960,000 for the
     year ended January 6, 1996 (after amortization of $18,229,000 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.

     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 market.  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.

     HOLDING COMPANY STRUCTURE

          The Notes and the Series C Preferred Stock issuable upon
     exchange thereof are obligations exclusively of the Company.  Since
     the operations of the Company are currently conducted primarily
     through subsidiaries, the cash flow and the consequent ability to
     service the Company's debt, including the Notes, and to pay
     dividends on any Series C Preferred Stock issued upon exchange
     thereof, are dependent upon the earnings of the Company's
     subsidiaries and the distribution of those earnings to, or upon
     loans or other payments of funds by those subsidiaries to, the
     Company.  The Company's subsidiaries are separate and distinct
     legal entities and have no obligation, contingent or otherwise, to
     pay any amounts due under the Notes or as dividends on Series C
     Preferred Stock issued upon exchange thereof or to make any funds
     available therefor, whether by dividends, loans or other payments.
     In addition, the payment of dividends and the making of loans and
     advances to the Company by its subsidiaries may be subject to
     statutory or contractual restrictions, are dependent upon the
     earnings of those subsidiaries and are subject to various business
     considerations.

          Any right of the Company to receive assets of any of its
     subsidiaries upon their liquidation or reorganization (and the
     consequent right of the holders of the Securities and the Comptons
     Shares to participate in those assets) is effectively subordinated
     to the claims of that subsidiary's creditors (including trade
     creditors), except to the extent that the Company is itself
     recognized as a creditor of such subsidiary, in which case the
     claims of the Company would still be subordinate to any security
     interests in the assets of such subsidiary and any indebtedness of
     such subsidiary senior to that held by the Company.

          Because the Company's operations are conducted primarily
     through its operating subsidiaries, claims of holders of
     indebtedness of such subsidiaries, as well as claims of trade
     creditors of such subsidiaries, have priority with respect to the
     assets and earnings of such subsidiaries over the claims of
     creditors of the Company, including holders of the Notes.  The
     Indenture does not limit the amount of additional indebtedness
     which the Company can create, incur, assume or guarantee, nor does
     the Indenture limit the amount of indebtedness which any of the
     Company's subsidiaries can create, incur, assume or guarantee.

     CHANGE OF CONTROL

          The Indenture and the Certificate of Designations of the
     Series C Preferred Stock (the "Certificate of Designations")
     provide that holders of the Notes and the Series C Preferred Stock
     have the right, in the event of a Change of Control, to require
     that the Company repurchase the Notes in whole or in part at a
     redemption price equal to 101% of the principal amount or
     liquidation preference thereof plus accrued interest or dividends,
     as the case may be.  There can be no assurance that the Company
     will have the financial resources necessary to purchase the Notes
     and the Series C Preferred Stock upon a Change of Control.  See
     "Description of Notes -- Change of Control" and "Description of
     Capital Stock -- Series C Preferred Stock -- Change of Control."

     LACK OF PUBLIC MARKET FOR THE NOTES AND SERIES C PREFERRED STOCK;
     VOLATILITY

          There is no existing trading market for the Notes or the
     Series C Preferred Stock, and there can be no assurance regarding
     the future development of a market for the Notes or the Series C
     Preferred Stock or the ability of holders thereof or the price at
     which such holders may be able to sell such securities.  If such
     markets were to develop, the Notes or the Series C Preferred Stock
     could trade at prices that may be higher or lower than the price at
     which they are sold hereunder depending on many factors, including
     prevailing interest rates, the Company's operating results and the
     market for similar securities.  There can be no assurance as to the
     liquidity of any trading market for the Notes or the Series C
     Preferred Stock or that an active public market therefor will
     develop.  The Company does not intend to apply for listing or
     quotation of the Notes or the Series C Preferred Stock on any
     securities exchange or automated quotation service.

          The Common Stock is quoted on the NNM.  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, general conditions in
     the computer hardware and software industries and general economic
     and political conditions may have a significant impact on the
     market price of the Notes, Series C Preferred Stock and Common
     Stock.

      RATIOS OF EARNINGS TO FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

          For the purpose of computing the ratio of earnings to fixed
     charges, earnings consist of the sum of (i) earnings before income
     taxes and (ii) fixed charges.  Fixed charges consist of interest on
     all indebtedness and amortization of debt-related expenses.  At
     December 31, 1995, the Company had paid no dividends on any Preferred
     Stock.  At December 31, 1995, fixed charges exceeded earnings by
     $60,165, which includes the effect of amortization and merger-
     related costs.  Excluding the effect of amortization and merger-
     related costs, the ratio of earnings to fixed charges at December
     31, 1995 would have been 8.39X.  Fixed charges prior to 1995 were
     deemed immaterial by the Company.

                               USE OF PROCEEDS

          The Company will not receive any proceeds from the sale of the
     Securities or the Comptons Shares by the Selling Holder.

                              THE SELLING HOLDER

          The Notes were initially issued and sold pursuant to a
     Securities Purchase Agreement dated as of November 30, 1995 between
     the Company and the Selling Holder.  The Comptons Shares were
     initially issued and sold pursuant to the Merger Agreement.  The
     Selling Holder acquired the Notes and the Compton Shares in
     transactions exempt from registration under the Securities Act.
     The Company has agreed to indemnify and hold the Selling Holder
     harmless against certain liabilities under the Securities Act that
     would arise in connection with sales of the Securities and the
     Comptons Shares by the Selling Holder.

          The table below sets forth certain information with respect to
     the Selling Holder, the Securities and the Comptons Shares as of
     April 1, 1996.  Unless the context otherwise requires, the term
     Selling Holder includes the beneficial owner (possessing sole
     voting and investment power) of the Securities and the Comptons
     Shares listed below.  Other than as a result of the ownership of
     the Securities and the Comptons Shares indicated below and as
     otherwise indicated herein, the Selling Holder has not had any
     material relationship with the Company or any of its affiliates
     within the past three years.

          The preceding table has been prepared based upon information
     furnished to the Company by the Trustee and by or on behalf of the
     Selling Holder.

          In view of the fact that the Selling Holder may offer for sale
     all or a portion of the Securities or the Comptons Shares held by
     it from time to time, no estimate can be given as to the amount of
     Notes or the number of shares of Series C Preferred Stock or Common
     Stock that will be held by the Selling Holder after completion of
     the offering made hereby.

          Information concerning the Selling Holder may change from time
     to time and any such changed information will be set forth in
     supplements to this Prospectus if and when necessary.  In addition,
     the per share exchange price and conversion price, and the number
     of shares of Series C Preferred Stock issuable upon exchange of the
     Notes or the number of shares of Common Stock issuable upon
     conversion of the Notes or the Series C Preferred Stock, are
     subject to adjustment under certain circumstances.  Accordingly,
     the aggregate principal amount of Notes, the number of shares of
     Series C Preferred Stock issuable upon exchange thereof or Common
     Stock issuable upon conversion of either the Notes or the Series C
     Preferred Stock offered hereby may increase or decrease.  As of the
     date of this Prospectus, the aggregate principal amount of Notes
     outstanding is $150,000,000.  As of the date hereof, none of the
     Notes has been exchanged for Series C Preferred Stock or has been
     converted into Common Stock.

          In connection with the execution and delivery of the Indenture
     and the Merger Agreement, the Company and Tribune entered into (i)
     the Standstill Agreement dated as of December 22, 1995 pursuant to
     which, among other agreements, Tribune agreed under certain
     circumstances to restrict its ownership in and voting of securities
     of the Company and the Company agreed (x) to take all necessary
     actions to increase the size of its Board of Directors (the "Board
     of Directors") by one and to fill the vacancy created thereby with
     an individual designated by Tribune and (y) if the Board of
     Directors shall at any time consist of 10 or more members, to take
     all necessary actions to increase further the size of the Board of
     Directors by one and to fill the additional vacancy created thereby
     with a second individual designated by Tribune and (ii) the Tax
     Sharing Agreement dated as of December 28, 1995 pursuant to which
     the Company and Tribune agreed to an allocation of certain tax
     liabilities and related matters.

                           DESCRIPTION OF THE NOTES

          The Notes are issued under the Indenture.  A copy of the
     Indenture has been filed with the Commission and is incorporated by
     reference as an exhibit to the Registration Statement.  The
     following summaries of certain provisions of the Notes and the
     Indenture do not purport to be complete and are subject to, and are
     qualified in their entirety by reference to, the Trust Indenture
     Act of 1939, as amended (the "Trust Indenture Act"), and all the
     provisions of the Notes and the Indenture, including the
     definitions therein of certain terms which are not otherwise
     defined in this Prospectus and those terms made a part of the
     Indenture by reference to the Trust Indenture Act.  Wherever
     particular provisions or defined terms of the Indenture (or of the
     form of Note which is a part thereof) are referenced herein, such
     provisions or defined terms are incorporated herein by reference.
     As used in this "Description of the Notes," the "Company" refers to
     SoftKey International Inc. and does not, unless the context
     otherwise indicates, include its subsidiaries.

     GENERAL

          The Notes are general unsecured obligations of the Company
     senior or pari passu in right of payment to all other unsecured
     obligations of the Company as described below under the subheading
     "Ranking," are exchangeable for Series C Preferred Stock (as
     described below under the subheading "Exchange of Notes"), and are
     convertible into Common Stock (as described below under the
     subheading "Conversion of Notes").  The Notes are limited to
     $150,000,000 aggregate principal amount, have been issued in fully
     registered form only in denominations of $1,000 or any multiple
     thereof and will mature on November 1, 2000, unless earlier
     redeemed at the option of the Company or at the option of the
     holders thereof upon a Change of Control.

          Except as described below with respect to the form of
     certificate of designation included as an exhibit to the Indenture,
     the Indenture does not contain any restrictions on the payment of
     dividends, the repurchase of securities of the Company or the
     incurrence of debt by the Company or any of its subsidiaries.

          The Notes bear interest from December 22, 1995 at the annual
     rate set forth on the cover page hereof, payable semi-annually on
     May 1 and November 1, commencing on May 1, 1996, to holders of
     record at the close of business on the preceding April 15 and
     October 15, respectively.  Interest is computed on the basis of a
     360-day year comprised of twelve 30-day months.

          Unless other arrangements are made, interest is paid by check
     mailed to holders entitled thereto.  Principal will be payable, and
     the Notes may be presented for exchange, conversion or registration
     of transfer and exchange, without service charge, at the office of
     the Trustee in New York, New York.

     EXCHANGE OF NOTES

          The holders of Notes are entitled at any time prior to the
     close of business on November 1, 2000, subject to prior redemption,
     to exchange any Notes or portions thereof (in denominations of
     $1,000 or multiples thereof) into Series C Preferred Stock, at the
     exchange price set forth on the cover page of this Prospectus,
     subject to adjustment as described below; provided that in the case
     of Notes called for redemption, exchange rights will expire at the
     close of business on the business day next preceding the date fixed
     for redemption, unless the Company defaults in payment of the
     redemption consideration.  A Note (or portion thereof) in respect
     of which a holder is exercising its option to require redemption
     upon a Change of Control may be exchanged only if such holder
     withdraws its election to exercise such option in accordance with
     the terms of the Indenture.  Except as described below, no
     adjustment will be made on exchange of any Notes for interest
     accrued thereon or for dividends on any Series C Preferred Stock
     issued.  Unless called for redemption, if Notes are exchanged after
     a record date for the payment of interest and prior to the next
     succeeding interest payment date, such Notes must be accompanied by
     funds equal to the interest payable on such succeeding interest
     payment date on the principal amount so exchanged.  Upon exchange,
     dividends on the Series C Preferred Stock issuable upon such
     exchange will commence to accrue as of the most recent date as of
     which interest has been paid on the Notes, unless no interest has
     been paid on the Notes, in which case dividends shall accrue from
     December 22, 1995.  The Company is not required to issue fractional
     shares of Series C Preferred Stock upon exchange of Notes and, in
     lieu thereof, will pay a cash adjustment based upon the greater of
     the liquidation preference of the Series C Preferred Stock or the
     current market value (on the last business day prior to the date of
     the exchange) of the number of shares of Common Stock into which
     one share of Preferred Stock may then be converted.

          The exchange price is subject to adjustment (in such manner as
     the Board of Directors shall determine is fair and equitable, which
     determination shall be conclusive and shall be set forth in a
     resolution of the Board of Directors) upon an amendment to the
     provisions of the Series C Preferred Stock as set forth in the
     Certificate of Designation relating to the Series C Preferred Stock
     to reduce the liquidation preference of, or the amount of dividends
     or other distributions payable with respect to, the Series C
     Preferred Stock, or to change the conversion price at which the
     Series C Preferred Stock is convertible into Common Stock pursuant
     to such Certificate of Designation.

          The exchange price will not be adjusted for the issuance of
     Series C Preferred Stock or any securities convertible into or
     exchangeable for Series C Preferred Stock or carrying the right to
     purchase any of the foregoing.  No adjustment in the exchange price
     will be required unless such adjustment would require a change of
     at least 1% in the exchange price then in effect; provided that any
     adjustment that would otherwise be required to be made shall be
     carried forward and taken into account in any subsequent
     adjustment.

          In the case of (i) any reclassification or change of the
     Series C Preferred Stock (other than changes in par value or to or
     from no par value resulting from a subdivision or a combination) or
     (ii) a consolidation, merger or combination involving the Company
     or a sale or conveyance to another corporation of the property and
     assets of the Company as an entirety or substantially as an
     entirety, in each case as a result of which holders of Series C
     Preferred Stock shall be entitled to receive stock, other
     securities, other property or assets (including cash) with respect
     to or in exchange for such Series C Preferred Stock, the holders of
     the Notes then outstanding will be entitled thereafter to exchange
     such Notes into the kind and amount of shares of stock, other
     securities or other property or assets (including cash) which they
     would have owned or been entitled to receive upon such
     reclassification, change, consolidation, merger, combination, sale
     or conveyance had such Notes been exchanged for Series C Preferred
     Stock immediately prior to such reclassification, change,
     consolidation, merger, combination, sale or conveyance assuming
     that a holder of Notes would not have exercised any rights of
     election as to the stock, other securities or other property or
     assets receivable in connection therewith.

          In the event of a taxable distribution to holders of Series C
     Preferred Stock (or other transaction) which results in any
     adjustment of the exchange price, the holders of Notes may, in
     certain circumstances, be deemed to have received a distribution
     subject to the United States income tax as a dividend; in certain
     other circumstances, the absence of such an adjustment may result
     in a taxable dividend to the holders of Series C Preferred Stock.

          The Company from time to time may, to the extent permitted by
     law, reduce the exchange price by any amount for any period of at
     least 20 days, in which case the Company shall give at least 15
     days' notice of such decrease to the holders of record of the
     Notes, if the Board of Directors has made a determination that such
     decrease would be in the best interests of the Company, which
     determination shall be conclusive.  A distribution of a stock
     dividend or of rights to acquire stock to the holders of Series C
     Preferred Stock that is not accompanied by a full adjustment of the
     exchange price of the Notes to take such distribution into account
     may result in a taxable dividend to the holders of Series C
     Preferred Stock.  The Company may, at its option, make such
     reductions in the exchange price, in addition to those set forth
     above, as the Company deems advisable to avoid or diminish any
     income tax to its stockholders resulting from any dividend or
     distribution of stock (or rights to acquire stock) or from any
     event treated as such for income tax purposes.

     CONVERSION OF NOTES

          The holders of Notes are entitled at any time prior to the
     close of business on November 1, 2000 to convert any Notes or
     portions thereof (in denominations of $1,000 or multiples thereof)
     into Common Stock, at the conversion price set forth on the cover
     page of this Prospectus, subject to adjustment as described below;
     provided that in the case of Notes called for redemption,
     conversion rights will expire at the close of business on the
     business day next preceding the date fixed for redemption, unless
     the Company defaults in payment of the redemption price.  Except as
     described below, no adjustment will be made on conversion of any
     Notes for interest accrued thereon or for dividends on any Common
     Stock issued.  Unless called for redemption, if Notes are converted
     after a record date for the payment of interest and prior to the
     next succeeding interest payment date, such Notes must be
     accompanied by funds equal to the interest payable on such
     succeeding interest payment date on the principal amount so
     converted.  The Company is not required to issue fractional shares
     of Common Stock upon conversion of Notes and, in lieu thereof, will
     pay a cash adjustment based upon the market price of the Common
     Stock on the last business day prior to the date of conversion.

          The conversion price is subject to adjustment (under formulae
     set forth in the Indenture) upon the occurrence of certain events,
     including: (i) the issuance of Common Stock as a dividend or
     distribution on Common Stock; (ii) the issuance to all holders of
     Common Stock of certain rights or warrants to purchase Common Stock
     at less than the current market price; (iii) certain subdivisions
     and combinations of Common Stock; (iv) distributions to all holders
     of Common Stock of capital stock of the Company (other than Common
     Stock) or evidences of indebtedness of the Company or assets
     (including securities, but excluding those dividends, rights,
     warrants and distributions referred to above and dividends and
     distributions in connection with the liquidation, dissolution or
     winding up of the Company and dividends and distributions paid
     exclusively in cash); (v) distributions consisting exclusively of
     cash (excluding any cash portion of distributions referred to in
     clause (iv)) to all holders of Common Stock in an aggregate amount
     that, combined together with all other such all-cash distributions
     and any cash plus the fair market value of consideration payable in
     respect of any tender offer, in any such case made within the
     preceding 12 months in respect of which no adjustment has been
     made, exceeds 20% of the Company's market capitalization (being the
     product of the then current market price of the Common Stock times
     the number of shares of Common Stock then outstanding) on the
     record date for such distribution; and (vi) the purchase of Common
     Stock pursuant to a tender offer made by the Company or any of its
     subsidiaries which involves an aggregate consideration that,
     together with (x) any cash and the fair market value of any other
     consideration payable in any other tender offer by the Company or
     any of its subsidiaries for Common Stock expiring within the 12
     months preceding such tender offer in respect of which no
     adjustment has been made and (y) the aggregate amount of such all-
     cash distributions referred to in clause (v) above to all holders
     of Common Stock within the 12 months preceding the expiration of
     such tender offer in respect of which no adjustments have been
     made, exceeds 20% of the Company's market capitalization on the
     expiration of such tender offer.  No adjustment of the conversion
     price will be made for shares of Common Stock issued pursuant to a
     plan for reinvestment of dividends or interest.

          Except as stated above, the conversion price will not be
     adjusted for the issuance of Common Stock or any securities
     convertible into or exchangeable for Common Stock or carrying the
     right to purchase any of the foregoing.  No adjustment in the
     conversion price will be required unless such adjustment would
     require a change of at least 1% in the conversion price then in
     effect; provided that any adjustment that would otherwise be
     required to be made shall be carried forward and taken into account
     in any subsequent adjustment.

          In the case of (i) any reclassification or change of the
     Common Stock (other than changes in par value or to or from no par
     value or resulting from a subdivision or a combination) or (ii) a
     consolidation, merger or combination involving the Company or a
     sale or conveyance to another corporation of the property and
     assets of the Company as an entirety or substantially as an
     entirety, in each case as a result of which holders of Common Stock
     shall be entitled to receive stock, other securities, other
     property or assets (including cash) with respect to or in exchange
     for such Common Stock, the holders of the Notes then outstanding
     will be entitled thereafter to convert such Notes into the kind and
     amount of shares of stock, other securities or other property or
     assets (including cash) which they would have owned or been
     entitled to receive upon such reclassification, change,
     consolidation, merger, combination, sale or conveyance had such
     Notes been converted into Common Stock immediately prior to such
     reclassification, change, consolidation, merger, combination, sale
     or conveyance, assuming that a holder of Common Stock would not
     have exercised any rights of election as to the stock, other
     securities or other property or assets receivable in connection
     therewith.

          If one of the events that results in an adjustment of the
     conversion price is treated for United States income tax purposes
     as a taxable dividend to holders of Common Stock (or other
     shareholders of the Company), the holders of Notes may be deemed to
     have received a distribution subject to United States income tax as
     a dividend.

          The Company from time to time may, to the extent permitted by
     law, reduce the conversion price by any amount for any period of at
     least 20 days, in which case the Company shall give at least 15
     days' notice of such decrease to the holders of record of the
     Notes, if the Board of Directors has made a determination that such
     decrease would be in the best interests of the Company, which
     determination shall be conclusive.  A distribution of a stock
     dividend or of rights to acquire stock to the holders of Common
     Stock that is not accompanied by a full adjustment of the
     conversion price of the Notes to take such distribution into
     account may result in a taxable dividend to the holders of Common
     Stock.  The Company may, at its option, make such reductions in the
     conversion price, in addition to those set forth above, as the
     Company deems advisable to avoid or diminish any income tax to its
     stockholders resulting from any dividend or distribution of stock
     (or rights to acquire stock) or from any event treated as such for
     income tax purposes.

     OPTIONAL REDEMPTION BY THE COMPANY

          The Notes are not redeemable at the option of the Company
     prior to November 2, 1998.  At any time on or after that date, the
     Notes may be redeemed at the Company's option on at least 30 but
     not more than 60 days' notice, in whole at any time or in part from
     time to time, at the following prices (expressed in percentages of
     the principal amount), together with accrued interest to the date
     fixed for redemption:

          If redeemed during the 12-month period beginning:

                                         Redemption
          Year                              Price

          November 2, 1998 . . . . . . . .      102.2%
          November 1, 1999 . . . . . . . .      101.1%

     and 100% at November 1, 2000.

          If fewer than all the Notes are to be redeemed, the Trustee
     will select the Notes to be redeemed in principal amounts of $1,000
     or integral multiples thereof by lot or, in its discretion, on a
     pro rata basis.  If any Note is to be redeemed in part only, a new
     Note or Notes in principal amount equal to the unredeemed principal
     portion thereof will be issued.  If a portion of a holder's Notes
     is selected for partial redemption and such holder converts a
     portion of such Notes after such selection, such converted portion
     shall be deemed to be taken from the portion selected for
     redemption.  No sinking fund is provided for the Notes.

     CHANGE IN CONTROL

          Upon the occurrence of a Change of Control, each holder of the
     Notes shall have the right to require that the Company repurchase
     such holder's Notes in whole or in part in integral multiples of
     $1,000, at a purchase price in cash in an amount equal to 101% of
     the principal amount thereof, together with accrued and unpaid
     interest thereon to the date of such repurchase, pursuant to an
     offer (the "Change of Control Offer") made in accordance with the
     procedures described below and the other provisions in the
     Indenture.

          A "Change of Control" means an event or series of events in
     which (i) any "person" or "group" (as such terms are used in
     Sections 13(d) and 14(d) of the Exchange Act) acquires "beneficial
     ownership" (as determined in accordance with Rule 13d-3 under the
     Exchange Act), directly or indirectly, of more than 50% of the
     total Voting Stock of the Company at an Acquisition Price (each
     term as defined herein) less than the conversion price then in
     effect with respect to the Notes and (ii) the holders of the Common
     Stock receive consideration which is not all or substantially all
     common stock that is (or upon consummation of or immediately
     following such event or events will be) listed on a United States
     national securities exchange or approved for quotation on the NNM
     or any similar United States system of automated dissemination of
     quotations of securities' prices; provided, however, that any such
     person shall not be deemed to be the beneficial owner of, or to
     beneficially own, any Voting Stock tendered into a tender offer
     until such tendered Voting Stock is accepted for purchase under the
     tender offer.  "Voting Stock" means stock of the class or classes
     pursuant to which the holders thereof have the general voting power
     under ordinary circumstances to elect at least a majority of the
     board of directors, managers or trustees of a corporation
     (irrespective of whether or not at the time stock of any other
     class or classes shall have or might have voting power by reason of
     the happening of any contingency).  "Acquisition Price" means the
     volume-weighted average price per share paid by the person or group
     in acquiring the Voting Stock.

          Within 30 days following any Change of Control, the Company
     shall send by first-class mail, postage prepaid, to the Trustee and
     to each holder of Notes, at such holder's address appearing in the
     security register, a notice stating, among other things, that a
     Change of Control has occurred, the purchase price, the purchase
     date, which shall be a business day no earlier than 30 days nor
     later than 60 days from the date such notice is mailed, and certain
     other procedures that a holder of the Notes must follow to accept a
     Change of Control Offer or to withdraw such acceptance.

          The Company will comply, to the extent applicable, with the
     requirements of Rule 13e-4 under the Exchange Act and other
     securities laws or regulations in connection with the repurchase of
     the Notes as described above.

          The occurrence of certain of the events which would constitute
     a Change of Control would constitute a default under the revolving
     line of credit of SoftKey Inc., a wholly owned subsidiary of the
     Company.  Future indebtedness of the Company may contain
     prohibitions of certain events which would constitute a Change of
     Control or require the Company to offer to redeem such indebtedness
     upon a Change of Control.  Moreover, the exercise by the holders of
     the Notes of their right to require the Company to purchase the
     Notes could cause a default under such indebtedness, even if the
     Change of Control itself does not, due to the financial effect of
     such purchase on the Company.  Finally, the Company's ability to
     pay cash to holders of the Notes upon a purchase may be limited by
     the Company's then existing financial resources.  There can be no
     assurance that sufficient funds will be available when necessary to
     make any required purchases.  Furthermore, the Change of Control
     provisions may in certain circumstances make more difficult or
     discourage a takeover of the Company and the removal of the
     incumbent management.

     RANKING

          The indebtedness of the Company evidenced by the Notes is
     senior and unsecured.  Because the Company's operations are
     conducted primarily through its operating subsidiaries, claims of
     holders of indebtedness of such subsidiaries, as well as claims of
     trade creditors of such subsidiaries, have priority with respect to
     the assets and earnings of such subsidiaries over the claims of
     creditors of the Company, including holders of the Notes.

          The Notes are obligations exclusively of the Company.  Since
     the operations of the Company are currently conducted primarily
     through subsidiaries, the cash flow and the consequent ability to
     service the Company's debt, including the Notes, and to redeem and
     pay dividends on any Series C Preferred Stock issuable upon
     exchange thereof are dependent upon the earnings of the Company's
     subsidiaries and the distribution of those earnings to, or upon
     loans or other payments of funds by those subsidiaries to, the
     Company.  The Company's subsidiaries are separate and distinct
     legal entities and have no obligation, contingent or otherwise, to
     pay any amounts due under the Notes or any Series C Preferred Stock
     issuable upon exchange thereof or to make any funds available
     therefor, whether by dividends, loans or other payments.  In
     addition, the payment of dividends and the making of loans and
     advances to the Company by its subsidiaries may be subject to
     statutory or contractual restrictions, are dependent upon the
     earnings of those subsidiaries and are subject to various business
     considerations.

          Any right of the Company to receive assets of any of its
     subsidiaries upon their liquidation or reorganization (and the
     consequent right of the holders of the Notes to participate in
     those assets) is effectively subordinated to the claims of that
     subsidiary's creditors (including trade creditors), except to the
     extent that the Company is itself recognized as a creditor of such
     subsidiary, in which case the claims of the Company would still be
     subordinate to any security interests in the assets of such
     subsidiary and any indebtedness of such subsidiary senior to that
     held by the Company.

          The Indenture does not limit the amount of additional
     indebtedness which the Company can create, incur, assume or
     guarantee, nor does the Indenture limit the amount of indebtedness
     which any subsidiary can create, incur, assume or guarantee.

     MERGER, CONSOLIDATION AND SALE OF ASSETS

          The Company shall not consolidate with or merge with or into,
     or convey, transfer or lease all or substantially all its assets to
     any person unless:  (i) either the Company is the resulting,
     surviving or transferee person (the "Successor Company") or the
     Successor Company is a person organized and existing under the laws
     of the United States or any State thereof or the District of
     Columbia, and the Successor Company (if not the Company) expressly
     assumes by a supplemental indenture, executed and delivered to the
     Trustee, in form satisfactory to the Trustee, all the obligations
     of the Company under the Indenture and the Notes, including the
     conversion rights described above under "Conversion of Notes;" (ii)
     immediately after giving effect to such transaction no Event of
     Default has happened and is continuing; and (iii) the Company
     delivers to the Trustee an Officers' Certificate and an opinion of
     counsel, each stating that such consolidation, merger or transfer
     and such supplemental indenture (if any) comply with the Indenture.

     EVENTS OF DEFAULT AND REMEDIES

          An Event of Default is defined in the Indenture as being:
     default in payment of the principal of or premium, if any, on the
     Notes; default for 30 days in payment of any installment of
     interest on the Notes; default by the Company for 90 days after
     notice in the observance or performance of any other covenants in
     the Indenture; or certain events involving bankruptcy, insolvency
     or reorganization of the Company.  The Indenture provides that the
     Trustee may withhold notice to the holders of Notes of any default
     (except in payment of principal, premium, if any, or interest with
     respect to the Notes) if the Trustee considers it in the interest
     of the holders of the Notes to do so.

          The Indenture provides that if any Event of Default shall have
     occurred and be continuing, the Trustee or the holders of not less
     than 25% in principal amount of the Notes then outstanding may
     declare the principal of and premium, if any, on the Notes to be
     due and payable immediately, but if the Company shall cure all
     defaults (except the nonpayment of interest on, premium, if any,
     and principal of any Notes which shall have become due by
     acceleration) and certain other conditions are met, such
     declaration may be cancelled, and past defaults may be waived by
     the holders of a majority in principal amount of Notes then
     outstanding.

          The holders of a majority in principal amount of the Notes
     then outstanding shall have the right to direct the time, method
     and place of conducting any proceedings for any remedy available to
     the Trustee, subject to certain limitations specified in the
     Indenture.

          The Company shall furnish to the Trustee, at least annually,
     evidence as to compliance with the terms of the Indenture.

     SATISFACTION AND DISCHARGE; DEFEASANCE

          The Indenture will cease to be of further effect as to all
     outstanding Notes (except, among other things, as to (i) rights of
     registration of transfer and exchange; (ii) substitution of
     apparently mutilated, defaced, destroyed, lost or stolen Notes;
     (iii) rights of holders of the Notes to receive payments of
     principal of and interest on the Notes; (iv) rights, obligations
     and immunities of the Trustee under the Indenture; and (v) rights
     of the holders of the Notes as beneficiaries of the Indenture with
     respect to the property so deposited with the Trustee payable to
     all or any of them), if (A) the Company will have paid or caused to
     be paid the principal of and interest on the Notes and all other
     amounts payable under the Indenture, all outstanding Notes (except
     lost, stolen or destroyed Notes which have been replaced or paid)
     have been delivered to the Trustee for cancellation and the Company
     has delivered to the Trustee an Officers' Certificate stating that
     all conditions relating to such defeasance have been satisfied or
     (B)(w) the Notes not previously delivered to the Trustee for
     cancellation will have become due and payable or are by their terms
     to become due and payable within one year or are to be called for
     redemption under arrangements satisfactory to the Trustee upon
     delivery of notice, (x) the Company will have irrevocably deposited
     with the Trustee, as trust funds, cash, in an amount sufficient to
     pay principal of and interest on the outstanding Notes, to maturity
     or redemption, as the case may be, (y) such deposit will not result
     in a breach or violation of, or constitute a default under, any
     agreement or instrument to which the Company is party or by which
     it is bound and (z) the Company has delivered to the Trustee an
     Officers' Certificate and an opinion of counsel, each stating that
     all conditions related to such defeasance have been complied with.

          The Indenture will also cease to be in effect (except, among
     other things, as described in clauses (i) through (v) in the
     immediately preceding paragraph) and the indebtedness on all
     outstanding Notes will be discharged on the 123rd day after the
     irrevocable deposit by the Company with the Trustee, in trust,
     specifically pledged as security for, and dedicated solely to, the
     benefit of the holders of the Notes, of cash, U.S. Government
     Obligations (as defined in the Indenture) or a combination thereof,
     in an amount sufficient, in the opinion of a nationally recognized
     firm of independent public accountants expressed in a written
     certification thereof delivered to the Trustee, to pay the
     principal of and interest on the Notes then outstanding in
     accordance with the terms of the Indenture and the Notes ("legal
     defeasance").  Such legal defeasance may only be effected if (i)
     such deposit will not result in a breach or violation of, or
     constitute a default under, any agreement or instrument to which
     the Company is party or by which it is bound; (ii) the Company has
     delivered to the Trustee an opinion of counsel stating that (A) the
     Company has received from, or there has been published by, the
     Internal Revenue Service a ruling or (B) since the date of the
     Indenture, there has been a change in the applicable federal income
     tax law, in either case to the effect that, based thereon, the
     holders of the Notes will not recognize income, gain or loss for
     federal income tax purposes as a result of such deposit, defeasance
     and discharge by the Company and will be subject to federal income
     tax in the same amount and in the same manner and at the same times
     as would have been the case if such deposit, defeasance and
     discharge had not occurred; (iii) the Company has delivered to the
     Trustee an opinion of counsel to the effect that after the 123rd
     day following the deposit, the trust funds will not be subject to
     the effect of any applicable bankruptcy, insolvency, reorganization
     or similar laws affecting creditors' rights generally; and (iv) the
     Company has delivered to the Trustee an Officer's Certificate and
     an opinion of counsel stating that all conditions related to the
     defeasance have been complied with.

          The Company may also be released from its obligations under
     the covenants described above under the subheadings "Change of
     Control" and "Merger, Consolidation and Sale of Assets" with
     respect to the Notes outstanding on the 123rd day after the
     irrevocable deposit by the Company with the Trustee, in trust,
     specifically pledged as security for, and dedicated solely to, the
     benefit of the holders of the Notes, cash, U.S. Government
     Obligations or a combination thereof, in an amount sufficient in
     the opinion of a nationally recognized firm of independent public
     accountants expressed in a written certification thereof delivered
     to the Trustee, to pay the principal of and interest on the Notes
     then outstanding in accordance with the terms of the Indenture and
     the Notes ("covenant defeasance").  Such covenant defeasance may
     only be effected if (i) such deposit will not result in a breach or
     violation of, or constitute a default under, any agreement or
     instrument to which the Company is a party or by which it is bound;
     (ii) the Company has delivered to the Trustee an opinion of counsel
     to the effect that the holders of the Notes will not recognize
     income, gain or loss for federal income tax purposes as a result of
     such deposit and covenant defeasance by the Company and will be
     subject to federal income tax in the same amount, in the same
     manner and at the same times as would have been the case if such
     deposit and covenant defeasance had not occurred; (iii) the Company
     has delivered to the Trustee an opinion of counsel to the effect
     that after 123rd day following the deposit, the trust funds will
     not be subject to the effect of any applicable bankruptcy,
     insolvency, reorganization or similar laws affecting creditors'
     rights generally; and (iv) the Company has delivered to the Trustee
     an Officers' Certificate and an opinion of counsel stating that all
     conditions related to the covenant defeasance have been complied
     with.  Following such covenant defeasance, the Company will no
     longer be required to comply with and will have no obligation to
     repurchase the Notes pursuant to the provisions described above
     under the subheadings "Change of Control."

     MODIFICATIONS OF THE INDENTURE

          The Indenture contains provisions permitting the Company and
     the Trustee, in certain cases with the consent of the holders of
     not less than a majority in principal amount of the Notes at the
     time outstanding, to modify the Indenture or any supplemental
     indenture or the rights of the holders of the Notes, except that no
     such modification shall (i) extend the fixed maturity of any Note,
     reduce the rate or extend the time for payment of interest thereon,
     reduce the principal amount thereof or premium, if any, thereon,
     reduce any amount payable upon redemption thereof, change the
     obligation of the Company to make redemption of any Note upon the
     happening of a Change of Control, impair or affect the right of a
     holder to institute suit for the payment thereof, change the
     currency in which the Notes are payable or impair the right to
     exchange the Notes for Series C Preferred Stock subject to the
     terms set forth in the Indenture or the right to convert the Notes
     into Common Stock subject to the terms set forth in the Indenture,
     without the consent of the holder of each Note so affected or (ii)
     reduce the aforesaid interest rate of Notes, without the consent of
     the holders of all of the Notes then outstanding.

     CONCERNING THE TRUSTEE

          State Street Bank and Trust Company, the Trustee under the
     Indenture, has been appointed by the Company as the paying agent,
     conversion agent, registrar and custodian with regard to the Notes.
     The Trustee and/or its affiliates have provided, are providing and
     may in the future provide banking and other services to the Company
     in the ordinary course of their respective businesses.

                         DESCRIPTION OF CAPITAL STOCK

          The Company's authorized capital stock consists of 60,000,000
     shares of Common Stock, 5,000,000 shares of preferred stock, par
     value $.01 per share (the "Preferred Stock"), and one share of
     special voting stock, par value $1.00 per share (the "Special
     Voting Share").

     COMMON STOCK

          Holders of Common Stock are entitled to one vote per share on
     all matters to be voted upon by the stockholders.  Subject to the
     rights of holders of outstanding Preferred Stock (including the
     Series C Preferred Stock), if any, the holders of Common Stock are
     entitled to receive such dividends, if any, as may be declared by
     the Board of Directors out of funds legally available therefor.  In
     the event of a liquidation, dissolution or winding up of the
     Company, holders of Common Stock have the right to a ratable
     portion of the assets remaining after payment of liabilities,
     subject to preferential payments required to be made to holders of
     outstanding Preferred Stock (including the Series C Preferred
     Stock), if any.  Holders of Common Stock do not have cumulative
     voting, preemptive, redemption or conversion rights.  All
     outstanding shares of Common Stock are, and the shares to be sold
     in this offering will be, fully paid and nonassessable.  The
     preferences and rights of holders of shares of Common Stock may
     become subject to those of holders of shares of any series of
     Preferred Stock (including the Series C Preferred Stock) which the
     Company may issue in the future.

     PREFERRED STOCK

          The Board of Directors has the authority, without further
     stockholder approval, to issue available shares of Preferred Stock
     in one or more series from time to time and to fix the powers,
     designations, preferences, and rights, and the qualifications,
     limitations, or restrictions of such preferences and/or rights.
     3,300,000 shares of the Preferred Stock have been retired and are
     no longer available for issuance.  Of the remaining 1,700,000
     shares of Preferred Stock available for issuance, 150,000 have been
     designated as Series C Preferred Stock, all of which are reserved
     for issuance upon exchange of the Notes.

          The Company has no current plans to issue any Preferred Stock
     other than the Series C Preferred Stock.  While the issuance of
     Preferred Stock could provide needed flexibility in connection with
     possible acquisitions and other corporate purposes, such issuance
     could also make it more difficult for a third party to acquire a
     majority of the outstanding voting stock of the Company or
     discourage an attempt to gain control of the Company.

     SERIES C PREFERRED STOCK

          The powers, preferences, rights, qualifications, limitations
     and restrictions of the Series C Preferred Stock are set forth in
     the Certificate of Designations.  A copy of the Certificate of
     Designation has been filed with the Commission as an exhibit to the
     Indenture and is incorporated by reference as an exhibit to the
     Registration Statement.  The following summaries of certain
     provisions of the Certificate of Designation do not purport to be
     complete and are subject to, and are qualified in their entirety by
     reference to, all the provisions of the Certificate of Designation,
     including the definitions therein of certain terms which are not
     otherwise defined in this Prospectus.  Wherever particular
     provisions or defined terms of the Certificate of Designation are
     referred to, such provisions or defined terms are incorporated
     herein by reference.  As used in this "Description of Capital
     Stock--Series C Preferred Stock", the "Company" refers to SoftKey
     International Inc. and does not, unless the context otherwise
     indicates, include its subsidiaries.

          General.  The Series C Preferred Stock, with respect to the
     payment of dividends and the distribution of assets on liquidation,
     dissolution or winding up, ranks prior to the Common Stock and on a
     parity with any other series of preferred stock hereafter issued by
     the Company.  The maximum authorized number of shares of Series C
     Preferred Stock is 150,000.  The Series C Preferred Stock is
     convertible at the option of the holders into Common Stock as
     described below under the subheading "Conversion Rights."  The
     liquidation preference of the Series C Preferred Stock is $1,000
     per share, plus an amount equal to all accrued and unpaid dividends
     thereon.

          Dividend Rights.  The holders of shares of the Series C
     Preferred Stock are entitled to receive, in preference to the
     holders of shares of Common Stock, dividends in an amount equal to
     51/2% per annum of the $1,000 per share liquidation preference of the
     Series C Preferred Stock.  Dividends are payable on May 1 and
     November 1 of each year (each such date a "Dividend Payment Date")
     to the persons in whose names the Series C Preferred Stock is
     registered at the close of business on the April 15 and October 15
     immediately preceding such Dividend Payment Date.  If dividends
     payable on shares of Series C Preferred Stock are not paid in full,
     then until all unpaid dividends have been paid in full or declared
     and set aside for payment, the Company may not (i) declare or pay
     dividends, or make any other distributions, on any shares of
     capital stock of the Company ranking junior ("Junior Stock") to the
     Series C Preferred Stock, except dividends or distributions payable
     in Junior Stock, or (ii) declare or pay dividends, or make any
     other distributions, on any shares of Company stock ranking on a
     parity with ("Parity Stock") the Series C Preferred Stock, except
     (A) dividends or distributions payable in Junior Stock and (B)
     dividends or distributions paid ratably on the Series C Preferred
     Stock and all Parity Stock in proportion to the total amounts to
     which holders of all the Series C Preferred Stock and Parity Stock
     are entitled; provided, however, that in the case of clause (B) the
     holders of at least 66-2/3% of the outstanding shares of Series C
     Preferred Stock, voting separately as a single class, or of at
     least 66-2/3% of the outstanding shares of Series C Preferred Stock
     and of Parity Stock (if the approval of the holders thereof is
     required for such a pro rata dividend or distribution under the
     applicable certificate of designation) voting together as a single
     class, shall have approved the payment of such dividend or
     distribution; and provided, further, that the provisions of this
     sentence will not apply upon the affirmative vote of the holders of
     66 2/3% of the outstanding shares of Series C Preferred Stock.

          If dividends payable on shares of Series C Preferred Stock are
     not paid in full, then until all unpaid dividends have been paid in
     full or declared and set aside for payment, the Company may not,
     subject to certain exceptions, redeem, purchase or otherwise
     acquire any shares of Series C Preferred Stock or any shares of
     capital stock of the Company ranking on a parity with ("Parity
     Stock"), or junior to, the Series C Preferred Stock.

          Conversion Rights.  The holders of shares of Series C
     Preferred Stock are entitled at any time prior to the close of
     business on November 1, 2000  to convert any shares of Series C
     Preferred Stock into that number of shares of Common Stock obtained
     by dividing $1,000 for each share of Series C Preferred Stock to be
     converted by the conversion price of $53 per share of Common Stock,
     which conversion price is subject to adjustment as provided below;
     provided that in the case of Series C Preferred Stock called for
     redemption, conversion rights will expire at the close of business
     on the business day next preceding the date fixed for redemption,
     unless the Company defaults in payment of the redemption price.
     The Company is not required to issue fractional shares of Common
     Stock upon conversion of Series C Preferred Stock and, in lieu
     thereof, will pay a cash adjustment based upon the market price of
     the Common Stock on the last business day prior to the date of
     conversion.

          The conversion price is subject to adjustment (under formulae
     set forth in the Certificate of Designation) upon the occurrence of
     certain events, including: (i) the issuance of Common Stock as a
     dividend or distribution on Common Stock; (ii) the issuance to all
     holders of Common Stock of certain rights or warrants to purchase
     Common Stock at less than the current market price; (iii) certain
     subdivisions and combinations of Common Stock; (iv) distributions
     to all holders of Common Stock of capital stock of the Company
     (other than Common Stock) or evidences of indebtedness of the
     Company or assets (including securities, but excluding those
     dividends, rights, warrants and distributions referred to above and
     dividends and distributions in connection with the liquidation,
     dissolution or winding up of the Company and dividends and
     distributions paid exclusively in cash); (v) distributions
     consisting exclusively of cash (excluding any cash portion of
     distributions referred to in clause (iv)) to all holders of Common
     Stock in an aggregate amount that, combined together with all other
     such all-cash distributions and any cash plus the fair market value
     of consideration payable in respect of any tender offer, in any
     such case made within the preceding 12 months in respect of which
     no adjustment has been made, exceeds 20% of the Company's market
     capitalization (being the product of the then current market price
     of the Common Stock times the number of shares of Common Stock then
     outstanding) on the record date for such distribution; and (vi) the
     purchase of Common Stock pursuant to a tender offer made by the
     Company or any of its subsidiaries which involves an aggregate
     consideration that, together with (x) any cash and the fair market
     value of any other consideration payable in any other tender offer
     by the Company or any of its subsidiaries for Common Stock expiring
     within the 12 months preceding such tender offer in respect of
     which no adjustment has been made and  (y) the aggregate amount of
     any all-cash distributions referred to in clause (v) above to all
     holders of Common Stock within the 12 months preceding the
     expiration of such tender offer in respect of which no adjustments
     have been made, exceeds 20% of the Company's market capitalization
     on the expiration of such tender offer.  No adjustment of the
     conversion price will be made for shares of Common Stock issued
     pursuant to a plan for reinvestment of dividends or interest.

          Except as stated above, the conversion price will not be
     adjusted for the issuance of Common Stock or any securities
     convertible into or exchangeable for Common Stock or carrying the
     right to purchase any of the foregoing.  No adjustment in the
     conversion price will be required unless such adjustment would
     require a change of at least 1% in the conversion price then in
     effect; provided that any adjustment that would otherwise be
     required to be made shall be carried forward and taken into account
     in any subsequent adjustment.

          In the case of (i) any reclassification or change of the
     Common Stock (other than changes in par value or to or from no par
     value resulting from a subdivision or a combination) or (ii) a
     consolidation, merger or combination involving the Company or a
     sale or conveyance to another corporation of the property and
     assets of the Company as an entirety or substantially as an
     entirety, in each case as a result of which holders of Common Stock
     shall be entitled to receive stock, other securities, other
     property or assets (including cash) with respect to or in exchange
     for such Common Stock, each share of Series C Preferred Stock then
     outstanding shall be convertible into the kind and amount of shares
     of stock, other securities or other property or assets (including
     cash) receivable upon such reclassification, change, consolidation,
     merger, combination, sale or conveyance by a holder of a number of
     shares of Common Stock issuable upon conversion of such share of
     Series C Preferred Stock immediately prior to such
     reclassification, change, consolidation, merger, combination, sale
     or conveyance assuming that a holder of Common Stock would not have
     exercised any rights of election as to the stock, other securities
     or other property or assets receivable in connection therewith.

          If one of the events that results in an adjustment of the
     conversion price is treated for United States income tax purposes
     as a taxable dividend to holders of Common Stock (or other
     shareholders of the Company), the holders of Series C Preferred
     Stock may be deemed to have received a distribution subject to
     United States income tax as a dividend.

          The Company from time to time may to the extent permitted by
     law, reduce the conversion price by any amount for any period of at
     least 20 days, in which case the Company shall give at least 15
     days' notice of such decrease to the holders of record of the
     Series C Preferred Stock, if the Board of Directors has made a
     determination that such decrease would be in the best interests of
     the Company, which determination shall be conclusive.  A
     distribution of a stock dividend or of rights to acquire stock to
     the holders of Common Stock that is not accompanied by a full
     adjustment of the conversion price of the Series C preferred Stock
     to take such distribution into account may result in a taxable
     dividend to the holders of Common Stock.  The Company may, at its
     option, make such reductions in the conversion price, in addition
     to those set forth above, as the Company deems advisable to avoid
     or diminish any income tax to its stockholders resulting from any
     dividend or distribution of stock (or rights to acquire stock) or
     from any event treated as such for income tax purposes.

          Change in Control.  Upon the occurrence of a Change of
     Control, each holder of the Series C Preferred Stock shall have the
     right to require that the Company repurchase such holder's Series C
     Preferred Stock in whole or in part at a purchase price in cash in
     an amount equal to 101% of the Liquidation Preference thereof,
     together with accrued and unpaid dividends thereon to the date of
     such repurchase, pursuant to a Change of Control Offer made in
     accordance with the procedures described below and the other
     provisions in the Certificate of Designation.

          Within 30 days following any Change of Control, the Company
     shall send by first-class mail, postage prepaid, to each holder of
     Series C Preferred Stock, at such holder's address appearing on the
     books of the Company, a notice stating, among other things, that a
     Change of Control has occurred, the purchase price, the purchase
     date, which shall be a business day no earlier than 30 days nor
     later than 60 days from the date such notice is mailed, and certain
     other procedures that a holder of the Series C Preferred Stock must
     follow to accept a Change of Control Offer or to withdraw such
     acceptance.

          The Company will comply, to the extent applicable, with the
     requirements of Rule 13e-4 under the Exchange Act and other
     securities laws or regulations in connection with the repurchase of
     the Series C Preferred Stock as described above.

          The occurrence of certain of the events which would constitute
     a Change of Control would constitute a default under the revolving
     line of credit of SoftKey Inc., a wholly owned subsidiary of the
     Company.  Future indebtedness of the Company may contain
     prohibitions of certain events which would constitute a Change of
     Control or require the Company to offer to redeem such indebtedness
     upon a Change of Control.  Moreover, the exercise by the holders of
     the Series C Preferred Stock of their right to require the Company
     to purchase the Series C Preferred Stock could cause a default
     under such indebtedness, even if the Change of Control itself does
     not, due to the financial effect of such purchase on the Company.
     Finally, the Company's ability to pay cash to holders of the Series
     C Preferred Stock upon a purchase may be limited by the Company's
     then existing financial resources.  There can be no assurance that
     sufficient funds will be available when necessary to make any
     required purchases.  Furthermore, the Change of Control provisions
     may in certain circumstances make more difficult or discourage a
     takeover of the Company and the removal of the incumbent
     management.

          Redemption.  The Company may, at its option, redeem all or,
     from time to time, any part of the Series C Preferred Stock at the
     redemption prices set forth below; provided, however, that no such
     redemption shall be effected before November 2, 1998; and provided,
     further, that on November 1, 2000, the Company shall redeem all of
     the Series C Preferred Stock then outstanding.  The redemption
     prices (expressed as percentages of the liquidation value of
     $1,000), together in each case with accrued and unpaid dividends
     thereon, whether or not declared, to the date of redemption, shall
     be as follows:

     If redeemed during the 12-month period beginning:

                    Date                Percentage

                    November 1, 1998         102.2%
                    November 1, 1999         101.1%

     and 100% on and after November 1, 2000.

          Voting Rights.  In addition to any voting rights provided by
     law, each share of Series C Preferred Stock entitles the holder
     thereof to vote on all matters voted on by holders of Common Stock,
     voting together as a single class.  With respect to any such vote,
     each share of Series C Preferred Stock shall entitle the holder
     thereof to cast the number of votes equal to the number of votes
     which could be cast in such vote by a holder of the shares of
     capital stock of the Company into which such share of Series C
     Preferred Stock is convertible on the record date for such vote.
     The affirmative vote of the holders of at least 66-2/3% of the
     outstanding shares of Series C Preferred Stock is necessary to (i)
     authorize, increase the authorized number of shares of or issue any
     shares of any class of capital stock ranking prior to the Series C
     Preferred Stock, (ii) increase the authorized number of shares of,
     or issue any shares of, Series C Preferred Stock, except in
     connection with the exchange of the Notes, (iii) authorize, adopt
     or approve an amendment to the Restated Certificate of
     Incorporation of the Company, as amended, that would decrease the
     aggregate number of authorized shares of Series C Preferred Stock,
     change the par value of the shares of Series C Preferred Stock, or
     adversely alter the rights of holders of the Series C Preferred
     Stock, (iv) authorize or issue shares of any class or series of
     stock with any preference or priority as to dividends or assets
     superior to any such preference or priority of the Series C
     Preferred Stock, or (v) reclassify any shares of Junior Stock into
     shares having any preference or priority as to dividends or
     liquidation superior to or on a parity with the Series C Preferred
     Stock.

          If on any date dividends payable on the Series C Preferred
     Stock shall have been in arrears and not paid in full for three
     semi-annual periods, whether or not consecutive, the number of
     directors constituting the Board of Directors shall be increased by
     two and the holders of shares of Series C Preferred Stock  shall
     have the right, voting separately as a single class (or as a class
     with the holders of shares of Parity Stock, if such holders are
     similarly entitled to elect additional directors), to elect
     directors to fill such newly created directorships.  Such
     additional directors shall continue as directors until such time as
     all dividends accumulated on the Series C Preferred Stock (and on
     the Parity Stock, if applicable) have been paid in full or all
     necessary funds have been set aside for payment.

          At each meeting of stockholders at which the holders of shares
     of Series C Preferred Stock shall have the right to take any
     action, the presence in person or by proxy of the holders of record
     of one-third of the total number of shares of Series C Preferred
     Stock then outstanding and entitled to vote shall be necessary to
     constitute a quorum.

     SPECIAL VOTING SHARE

          The Company's sole authorized and outstanding Special Voting
     Share is held of record by The R-M Trust Company, as Trustee (the
     "Special Voting Share Trustee"), under a Voting and Exchange Trust
     Agreement pursuant to which each holder of Exchangeable Non-Voting
     Shares of SoftKey Software Products Inc. (the "Exchangeable
     Shares"), other than the Company or any entity controlled by the
     Company (a "Controlled Entity"), is entitled to instruct the
     Special Voting Share Trustee to exercise one of the votes attached
     to the Special Voting Share for each Exchangeable Share held by
     such holder.  Except as otherwise required by law or the Company's
     Restated Certificate of Incorporation, as amended, the holder of
     record of the Special Voting Share will have a number of votes
     equal to the number of Exchangeable Shares outstanding from time to
     time not owned by the Company or any Controlled Entity.  The
     holders of shares of the Common Stock and the Special Voting Share
     vote together as a single class on all matters, except as may be
     required by applicable law.  The holder of the Special Voting Share
     is not entitled to receive dividends.  In the event of any
     liquidation, dissolution or winding-up of the Company, the holder
     of the Special Voting Share will not be entitled to receive any
     assets of the Company available for distribution to its
     stockholders.  At such time as the Special Voting Share has no
     votes attached to it because there are no Exchangeable Shares
     outstanding not owned by the Company or a Controlled Entity, and
     there are no shares of stock, debt, options or other agreements of
     the Company which could give rise to the issuance of any
     Exchangeable Shares to any person (other than the Company or a
     Controlled Entity), the Special Voting Share will be cancelled.

          The Exchangeable Shares were originally issued to certain
     holders of common shares of Former SoftKey in the Three-Party
     Combination.  All Exchangeable Shares not exchanged for an
     equivalent number of shares of Common Stock by February 4, 2005
     (the "Redemption Date") will be redeemed by SoftKey Software
     Products Inc., an Ontario corporation and a subsidiary of the
     Company ("SoftKey Software"), for a price per share equal to the
     current market price of a share of Common Stock (which shall be
     paid in Common Stock) plus a cash amount equivalent to the full
     amount of all unpaid dividends thereon, and the Special Voting
     Share will thereupon be cancelled.  The Board of Directors of
     SoftKey Software may extend the Redemption Date or, if at any time
     there are less than 50,000 outstanding Exchangeable Shares (other
     than Exchangeable Shares held by the Company or any Controlled
     Entity, subject to adjustment to reflect permitted changes to the
     Exchangeable Shares), accelerate the Redemption Date.

     TRANSFER AGENT AND REGISTRAR

          The Company has appointed The First National Bank of Boston as
     transfer agent and registrar of the Common Stock and the Series C
     Preferred Stock.

                             PLAN OF DISTRIBUTION

          The Securities and the Comptons Shares covered hereby may be
     offered and sold from time to time by the Selling Holder.  The
     Selling Holder will act independently of the Company in making
     decisions with respect to the timing, manner and size of each sale.
     Sales of the Securities and the Comptons Shares are, in general,
     expected to be made at the market price prevailing at the time of
     each such sale; however, prices in negotiated transactions may
     differ considerably.  Such sales may be made directly by the
     Selling Holder or in the over-the-counter market or otherwise, at
     fixed prices, at market prices prevailing at the time of sale, at
     prices related to the then prevailing market prices or in
     negotiated transactions, including without limitation pursuant to
     an underwritten public offering or pursuant to one or more of the
     following methods:  (a) purchases by a broker-dealer as principal
     and resale by such broker or dealer for its account pursuant to
     this Prospectus; (b) ordinary brokerage transactions and
     transactions in which a broker solicits purchasers; and (c) crosses
     and block trades in which a broker-dealer so engaged will attempt
     to sell the Securities and the Comptons Shares as agent but may
     take a position and resell a portion of the block as principal to
     facilitate the transaction.

          The Company has been advised that, as of the date hereof, the
     Selling Holder has made no arrangement with any broker for the
     offering or sale of the Securities or the Comptons Shares.
     Underwriters, brokers, dealers or agents may participate in such
     transactions as agents and may, in such capacity, receive brokerage
     commissions from the Selling Holder or purchasers of such
     securities.  Such underwriters, brokers, dealers or agents may also
     purchase the  Securities or the Comptons Shares and resell such
     securities for their own account.  The Selling Holder and such
     underwriters, brokers, dealers or agents may be considered
     "underwriters" as that term is defined by the Securities Act,
     although the Selling Holder disclaims such status.  Any
     commissions, discounts or profits received by such underwriters,
     brokers, dealers or agents in connection with the foregoing
     transactions may be deemed to be underwriting discounts and
     commissions under the Securities Act.

          To comply with the securities laws of certain jurisdictions,
     if applicable, the Securities and the Comptons Shares will be
     offered or sold in such jurisdictions only through registered or
     licensed brokers or dealers.  In addition, in certain
     jurisdictions, the Securities and the Comptons Shares may not be
     offered or sold unless they have been registered or qualified for
     sale in such jurisdictions or unless an exemption from such
     registration or qualification is available and is complied with.

          Under applicable rules and regulations under the Exchange Act,
     any person engaged in a distribution of the Securities and the
     Comptons Shares may be limited in its ability to engage in market
     activities with respect to such Securities.  In addition and
     without limiting the foregoing, the Selling Holder will be subject
     to applicable provisions of the Exchange Act and the rules and
     regulations thereunder, which provisions may limit the timing of
     purchases and sales of any of the Securities or the Comptons Shares
     by the Selling Holder.  All of the foregoing may affect the
     marketability of the Securities or the Compton Shares.

          The Company may suspend the use of this Prospectus and any
     supplements hereto in certain circumstances due to pending
     corporate developments, public filings with the commission or
     similar events.  The Company is obligated in the event of such
     suspension to use its reasonable efforts to ensure that the use of
     the Prospectus (as amended or supplemented as necessary) may be
     resumed as soon as practicable.

          The Company has agreed to pay all of the expenses incident to
     the registration, offering and sale to the public of the Securities
     or the Comptons Shares other than commissions and discounts of
     agents, dealers or underwriters.  Such expenses (excluding such
     commissions and discounts) are estimated to be approximately
     $225,000.  The Company has also agreed to indemnify the Selling
     Holder against certain liabilities, including certain liabilities
     under the Securities Act.

                                LEGAL MATTERS

          The validity of the Securities and the Comptons Shares offered
     hereby will be passed upon for the Company by Neal S. Winneg,
     General Counsel of the Company.  Mr. Winneg owns options to
     purchase an aggregate of 114,375 shares of Common Stock, which are
     or become exercisable in periodic installments through February
     1999.

                                   EXPERTS

          The consolidated financial statements and related schedule of
     the Company as of and for the years ended January 6, 1996 and
     December 31, 1994, included in the Company's Annual Report on Form
     10-K for the year ended January 6, 1996, have been audited by
     Coopers & Lybrand L.L.P., independent public accountants, as set
     forth in their report therein dated February 20, 1996 and
     incorporated herein by reference in reliance on such report, given
     on the authority of that firm as experts in accounting and
     auditing.  The consolidated statements of operations, stockholders'
     equity (deficit) and cash flows and the related financial statement
     schedule of the Company for the six month transition period from
     July 4, 1993 to January 1, 1994 and for the year ended June 30,
     1993, included in the Company's Annual Report on Form 10-K for the
     year ended January 6, 1996, have been audited by Arthur Andersen
     LLP, independent public accountants, as indicated in their report
     therein dated January 16, 1995 and incorporated herein by
     reference.  In its report, Arthur Andersen LLP states that with
     respect to the consolidated statements of operations, stockholders'
     equity (deficit) and cash flows and the related financial statement
     schedule of WordStar and Spinnaker for the year ended June 30,
     1993, its opinion is based on the reports of other independent
     accountants, namely KPMG Peat Marwick LLP and Price Waterhouse LLP,
     respectively.  The consolidated statements of operations,
     stockholders' equity (deficit) and cash flows and the related
     financial statement schedule of the Company have been included
     therein in reliance upon the authority of those firms as experts in
     accounting and auditing.  The report of Price Waterhouse LLP on the
     consolidated financial statements of Spinnaker for the year ended
     June 30, 1993 contains an explanatory paragraph relating to
     Spinnaker's ability to continue as a going concern as described in

     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 damage 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:

         "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
     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."

         SoftKey has purchased directors' and officers' liability
     insurance which would indemnify the directors and officers of
     SoftKey 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 SoftKey'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.

     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 to include any material information with
     respect to the plan of distribution not previously disclosed in the
     registration statement or any material change to such information
     in the registration statement;

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

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

               Insofar as indemnification for liabilities arising under
     the Securities Act of 1933 may be permitted to directors, officers
     and controlling persons of the Registrant pursuant to the
     provisions described in Item 15 above, 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.


                                  SIGNATURES

                Pursuant to the requirements of the Securities Act of
     1933, the Registrant certifies that it has reasonable grounds to
     believe that it meets all of the requirements for filing on Form S-
     3 and has duly caused this Registration Statement to be signed on
     its behalf by the undersigned, thereunto duly authorized, in the
     City of Cambridge, the Commonwealth of Massachusetts on April 9,
     1996.

               as the "Registrable Securities"), provided that the
               Holders thereof shall have provided the information
               required pursuant to Section 3(b) hereof; and

                    (ii) use all reasonable efforts to cause the
               Registration Statement to be declared effective by
               the Commission as promptly as practicable after the

          Subject to any notice by the Company in accordance with
          Section 4(b) hereof of the existence of any fact or event

          Registration Statement continuously effective,
          supplemented and amended as required by the provisions of
          Sections 4(a) and (b) hereof to the extent necessary to
          ensure that it is available for resales of Transfer
          Restricted Securities by the Holders of Transfer
          Restricted Securities entitled to the benefit of this
          Section 3(a) and to ensure that the Registration

          the Act and the policies, rules and regulations of the
          Commission as announced from time to time thereunder for

                    (b)  Certificated Securities; Provision by

          Securities may include any of its Transfer Restricted
          Securities in the Registration Statement pursuant to this
          Agreement unless (i) such Holder holds such Transfer
          Restricted Securities in the form of physical
          certificates and (ii) until such Holder furnishes to the
          Company in writing, within 20 business days after receipt
          of a request therefor, such information as the Company
          may reasonably request for use in connection with the
          Registration Statement or any Prospectus or preliminary
          Prospectus included therein.  In connection with all such
          requests for information from Holders of Registrable
          Securities, the Company shall notify such Holders of the
          requirements set forth in the preceding sentence.  Each
          Holder as to which the Registration Statement is being
          effected agrees to furnish promptly to the Company all
          information required to be disclosed in order to make the
          information previously furnished to the Company by such
          Holder not materially misleading.

          SECTION 4.  REGISTRATION PROCEDURES

                    (a)  In connection with the Registration
          Statement, the Company shall comply with all the
          provisions of Section 4(b) below and shall use all
          reasonable efforts to effect such registration to permit
          the resale of the Registrable Securities being sold in
          accordance with the intended method or methods of
          distribution thereof.

                    (b)  In connection with the Registration

               requisite financial statements for the period
               specified in Section 3 of this Agreement; upon the

               Registration Statement or the Prospectus contained
               therein (A) to contain a material misstatement or
               omission or (B) not to be effective and usable for
               resales of Registrable Securities during the period
               required by this Agreement, the Company shall file
               promptly an appropriate amendment to the
               Registration Statement correcting any such
               misstatement or omission, and, in the case of either
               clause (A) or (B), except as set forth in Section
               4(b)(xv) below, use all reasonable efforts to cause
               such amendment to be declared effective and the
               Registration Statement and the related Prospectus to
               become usable for their intended purpose(s) as soon
               as practicable thereafter;

                    (ii) prepare and file with the Commission such
               amendments and post-effective amendments to the
               Registration Statement as may be necessary to keep
               the Registration Statement effective for the
               applicable period set forth in Section 3 hereof, or
               such shorter period as will terminate when all
               Registrable Securities covered by the Registration
               Statement have been sold; cause the Prospectus to be
               supplemented by any required Prospectus supplement,
               and as so supplemented, cause the Prospectus to be
               filed pursuant to Rule 424 under the Act and to
               comply fully with the applicable provisions of Rules
               424 and 430A under the Act in a timely manner; and
               comply with the provisions of the Act with respect
               to the disposition of all securities covered by the
               Registration Statement during the applicable period
               in accordance with the intended method or methods of
               distribution by the sellers thereof set forth in the
               Registration Statement or supplement to the
               Prospectus;

                    (iii)  advise the underwriter(s), if any, and
               selling Holders promptly and, if requested by such
               Persons, to confirm such advice in writing, (A) when
               the Prospectus or any Prospectus supplement or post-
               effective amendment to the Registration Statement
               has been filed, and, with respect to the
               Registration Statement or any post-effective
               amendment thereto, when the same has become
               effective, (B) of any request by the Commission for
               amendments to the Registration Statement or
               amendments or supplements to the Prospectus or for
               additional information relating thereto, (C) of the
               issuance by the Commission of any stop order
               suspending the effectiveness of the Registration
               Statement under the Act or of the suspension by any
               state securities commission of the qualification of
               the Registrable Securities for offering or sale in
               any jurisdiction or of the initiation of any
               proceeding for any of the preceding purposes, (D) of
               the existence of any fact or the happening of any
               event (including without limitation pending
               negotiations relating to, or the consummation of, a
               transaction or the occurrence of any other event
               which would require additional disclosure of
               material, nonpublic information by the Company in
               the Registration Statement as to which the Company
               has a bona fide business purpose for preserving
               confidentiality or which renders the Company unable
               to comply with Commission requirements) that makes
               untrue any statement of a material fact made in the
               Registration Statement, the Prospectus, any
               amendment or supplement thereto or any document
               incorporated by reference therein, or that requires
               the making of any additions to or changes in the
               Registration Statement or the Prospectus in order to
               make the statements therein not misleading.  If at
               any time the Commission shall issue any stop order
               suspending the effectiveness of the Registration
               Statement, or any state securities commission or
               other regulatory authority shall issue an order
               suspending the qualification or exemption from
               qualification of the Registrable Securities under
               state securities or Blue Sky laws, the Company shall
               use its best efforts to obtain the withdrawal or
               lifting of such order at the earliest possible time;

                    (iv)  furnish to each of the selling Holders,
               upon request, and to each of the underwriter(s), if
               any, before filing with the Commission, copies of
               the Registration Statement or any Prospectus
               included therein and any amendments or supplements
               thereto (including all documents incorporated by
               reference prior to the effectiveness of the
               Registration Statement), which documents, other than
               documents incorporated by reference, will be subject
               to the review of such Holders and underwriter(s), if
               any, for a period of at least five business days,
               and the Company shall not file the Registration
               Statement or Prospectus or any amendment or
               supplement to the Registration Statement or
               Prospectus to which a selling Holder of Registrable 
               Securities covered by the Registration Statement or
               the underwriter(s), if any, shall reasonably object
               within five business days after the receipt thereof;
               a selling Holder or underwriter(s), if any, shall be
               deemed to have reasonably objected to such filing
               only if the Registration Statement, amendment,
               Prospectus or supplement, as applicable, as proposed
               to be filed, contains a material misstatement or
               omission;

                    (v)  if practicable, promptly prior to the
               filing of any document that is to be incorporated by
               reference into the Registration Statement or
               Prospectus subsequent to the effectiveness thereof,
               and in any event no later than the date such
               document is filed with the Commission, provide
               copies of such document to the selling Holders, if
               requested, and to the underwriter(s), if any, make

               disposition in such jurisdictions of the Registrable
               Securities covered by the Registration Statement;
               provided, however, that the Company shall not be
               required to register or qualify as a foreign
               corporation where it is not now so qualified or to
               take any action that would subject it to service of
               process in suits or to taxation, other than as to
               matters and transactions relating to the
               Registration Statement, in any jurisdiction where it
               is not now so subject;

                    (xiii) cooperate with the selling Holders and
               the underwriter(s), if any, to facilitate the timely
               preparation and delivery of certificates
               representing Transfer Restricted Securities to be
               sold and not bearing any restrictive legends; and
               enable such Registrable Securities to be in such
               denominations and registered in such names as the
               Holders or the underwriter(s), if any, may request
               at least two business days prior to any sale of
               Registrable  Securities made by such underwriter(s);

                    (xiv)  use all reasonable efforts to cause the
               Transfer Restricted Securities covered by the
               Registration Statement to be registered with or
               approved by such other governmental agencies or
               authorities as may be necessary to enable the seller
               or sellers thereof or the underwriter(s), if any, to
               consummate the disposition of such Registrable
               Securities, subject to the proviso contained in

               supplement or post-effective amendment to the

               document incorporated therein by reference or file
               any other required document so that, as thereafter
               delivered to the purchasers of Transfer Restricted
               Securities, the Prospectus will not contain an
               untrue statement of a material fact or omit to state
               any material fact necessary, in light of the
               circumstances in which it was made, to make the
               statements therein not misleading, provided,
               however, that notwithstanding anything to the
               contrary herein, the Company shall not be required
               to prepare and file such a supplement or post-
               effective amendment or document if the fact no
               longer exists; and provided further however, that,
               in the event of a material business transaction
               (including without limitation pending negotiations
               relating to such transaction) which based upon the
               advice of outside counsel reasonably acceptable to
               the Purchaser, would require disclosure by the
               Company in the Registration Statement of material,
               nonpublic information which the Company has a bona
               fide business purpose for not disclosing, then for
               so long as such circumstances and such business
               purpose continue to exist (provided that such period
               may not exceed 120 days in any calendar year), the
               Company shall not be required to prepare and file a
               supplement or post-effective amendment hereunder;

                    (xvi)  provide a CUSIP number for all Transfer

               the rules and regulations of the NASD, and use all
               reasonable efforts to cause the Registration
               Statement to become effective and be approved by
               such governmental agencies or authorities as may be
               necessary to enable the Holders selling Registrable
               Securities to consummate the disposition of such
               Transfer Restricted Securities;

                    (xviii)  otherwise use its reasonable efforts
               to comply with all applicable rules and regulations
               of the Commission, and make generally available to

               for the twelve-month period (A) commencing at the
               end of any fiscal quarter in which Transfer

               Commission to enable such Indenture to be so
               qualified in a timely manner;

                    (xx) cause all Registrable  Securities covered
               by the Registration Statement to be listed on any
               securities exchange on which similar securities

               of the Preferred Shares, or the managing

          the Company of the existence of any fact or event of the
          kind described in Section 4(b)(iii)(D) hereof, such

          copies of a supplemented or amended Prospectus as
          contemplated by Section 4(b)(xv) hereof, or until it is
          advised in writing (the "Advice) by the Company that the
          use of the Prospectus may be resumed, and, has received
          copies of any additional or supplemental filings that are
          incorporated by reference in the Prospectus.  If so
          directed by the Company, each Holder will deliver to the
          Company (at the expense of the Company) all copies, other
          than permanent file copies then in such Holder's
          possession, of the Prospectus covering such Registrable
          Securities that was current at the time of receipt of
          such notice.  In the event the Company shall give any
          such notice, the time period regarding the effectiveness

          Advice.

             Each Holder, by acquisition of a Transfer Restricted
          Security, agrees that, to the extent that (A) such Holder
          is deemed to be an "affiliate" of the Company for

          entered into a business combination transaction intended
          to be accounted for as a pooling of interests and (ii)
          such accounting treatment requires affiliates of the
          Company to not dispose of or otherwise reduce such
          affiliate's risk with respect to any Common Stock of the
          Company during the period beginning 30 days prior to the
          effective date of the transaction and until after such
          time as results covering at least 30 days of combined
          operations of the combined entity have been published,
          such Holder shall deliver to the Company an "affiliate
          letter" in reasonable and customary form and reasonably
          satisfactory to the Company.

          fees and expenses of counsel to any Indemnified Holder)
          directly or indirectly caused by, related to, based upon,
          arising out of or in connection with any untrue statement
          or alleged untrue statement of a material fact contained
          in the Registration Statement or any Prospectus (or any
          amendment or supplement thereto) or any omission or
          alleged omission to state therein a material fact required 
          to be stated therein or necessary to make the statements
          therein, in the light of the circumstances under which
          they were made, not misleading, except insofar as such
          Losses are caused by an untrue statement or omission or
          alleged untrue statement or omission that is made in
          reliance upon and in conformity with information relating
          to any of the Holders furnished in writing to the Company
          by any of the Holders for use therein.  The Company shall
          notify the Holders promptly of the institution, threat or
          assertion of any claim, proceeding (including any
          governmental investigation) or litigation in connection
          with the matters addressed by this Agreement which
          involves the Company or any Indemnified Holder.

             (b)  In case any action or proceeding (including,
          without limitation, any governmental or regulatory
          investigation or proceeding) shall be brought or asserted
          against any of the Indemnified Holders with respect to
          which indemnity may be sought against the Company, such
          Indemnified Holder (or the Indemnified Holder controlled
          by such controlling person) shall promptly notify the
          Company in writing (provided that the failure to give
          such notice shall not relieve the Company of its
          obligations pursuant to this Agreement).  Any Indemnified
          Holder shall have the right to employ separate counsel in
          any such action and participate in the defense thereof,
          but the fees and expenses of such counsel shall be at the
          expense of such Indemnified Holder, provided, however,
          that the fees and expenses of such counsel shall be at
          the expense of the Company if (i) the Company has failed
          to assume the defense and employ counsel reasonably
          satisfactory to the Holders or (ii) the named parties to
          any such action (including impleaded parties) include
          such Indemnified Holder and the Company and such
          Indemnified Holder shall have reasonably concluded that
          there may be one or more legal defenses available to it
          that are different from or in addition to those available
          to the Company; provided further that the Company shall
          not in such event be responsible hereunder for the fees
          and expenses of more than one firm of separate counsel,
          which firm shall be designated by the Holders, in
          connection with any action in the same jurisdiction, in
          addition to any local counsel.  The Company shall not be
          liable for any settlement of any such action or
          proceeding effected with its prior written consent, which
          consent shall not be unreasonably withheld or delayed,
          and the Company agrees to indemnify and hold harmless any
          Indemnified Holder from and against any Loss by reason of
          any settlement of any action effected with its written
          consent.  The Company shall not, without the prior
          written consent of each Indemnified Holder, settle or
          compromise or consent to the entry of a judgment in or
          otherwise seek to terminate any pending or threatened
          action, claim, litigation or proceeding in respect of
          which indemnification or contribution may be sought
          hereunder (whether or not any Indemnified Holder is a
          party thereto) unless such settlement, compromise,
          consent or termination includes an unconditional release
          of each Indemnified Holder from all liability arising out
          of such action, claim, litigation or
          proceeding.

             (c)  Each Holder of Transfer Restricted  Securities
          agrees, severally and not jointly, to indemnify and hold
          harmless the Company, its directors, its officers, and
          any person controlling (within the meaning of Section 15
          of the Act or Section 20 of the Exchange Act) the
          Company, and the respective officers, directors,
          partners, employees, representatives and agents of each
          such person, to the same extent as the foregoing
          indemnity from the Company to each of the Indemnified
          Holders, but only with respect to claims and actions
          based on information relating to such Holder furnished in
          writing by such Holder for use in the Registration
          Statement or any Prospectus.  In case any action or
          proceeding shall be brought against any of the Company or
          its directors or officers or any such controlling person
          in respect of which indemnity may be sought against a
          Holder of Transfer Restricted  Securities, such Holder
          shall have the rights and duties given the Company, and
          each of the Company or its directors or officers of such
          controlling person shall have the rights and duties given
          to each Holder by the proceeding paragraph.  In no event
          shall the liability of any selling Holder hereunder be
          greater in amount than the dollar amount of the proceeds
          received by such Holder upon the sale of the securities
          registered pursuant to provisions hereof giving rise to
          such indemnification obligation.

             (d)  If the indemnification provided for in this
          Section 6 is unavailable to a party entitled to
          indemnification in respect of any Losses referred to
          herein, then each indemnifying party, in lieu of
          indemnifying such indemnified party, shall contribute to
          the amount paid or payable by such indemnified party as a
          result of such Losses (i) in such proportion as is
          appropriate to reflect the relative benefits received by
          the Company on the one hand and the Holders on the other
          hand from their sale of Transfer Restricted  Securities
          or (ii) if such allocation is not permitted by applicable
          law, the relative fault of the Company on the one hand
          and of the indemnified Holder on the other in connection
          with the statements or omissions which resulted in the
          Losses as well as any relevant equitable considerations. 
          The relative fault of the Company on the one hand and of
          the Indemnified Holder on the other shall be determined
          by reference to, among other things, whether the untrue
          or alleged untrue statement of a material fact or the
          omission or alleged omission to state a material fact
          relates to information supplied by the Company or by the
          Indemnified Holder and the parties' relative intent,
          knowledge, access to information and opportunity to
          correct or prevent such statement or omission.  The
          indemnity and contribution obligations of each
          indemnifying party set forth herein shall be in addition
          to any liability or obligation such indemnifying party
          may otherwise have to any indemnified party.

               The Company and each Holder of Transfer Restricted 
          Securities agree that it would not be just and equitable
          if contribution pursuant to this Section 6(d) were
          determined by pro rata allocation (even if Holders were treated 
          as one entity for such purpose) or by any other method of
          allocation which does not take account of the equitable
          considerations referred to in the immediately preceding
          paragraph.  The amount paid or payable by an indemnified
          party as a result of the Losses referred to in the
          immediately preceding paragraph shall be deemed to
          include, subject to the limitations set forth above, any
          legal or other expenses reasonably incurred by such
          indemnified party in connection with investigating or
          defending any such action or claim.  Notwithstanding the
          provisions of this Section 6, none of the Holders (and
          their related Indemnified Holders) shall be required to
          contribute, in the aggregate, any amount in excess of the
          amount by which the total proceeds received by such
          Holder with respect to the Notes exceeds the amount of
          any damages which such Holder has otherwise been required
          to pay by reason of such untrue or alleged untrue
          statement or omission or alleged omission.  No person
          guilty of fraudulent misrepresentation (within the
          meaning of Section 11(f) of the Act) shall be entitled to
          contribution from any person who was not guilty of such
          fraudulent misrepresentation.  The Holders' obligations
          to contribute pursuant to this Section 6(d) are several
          in proportion to the respective principal amount of Notes
          held by each of the Holders hereunder and not joint.

          SECTION 7. RULE 144A

             The Company hereby agrees with each Holder, for so
          long as any Transfer Restricted Securities remain
          outstanding, to make available to any Holder or
          beneficial owner of Transfer Restricted  Securities in
          connection with any sale thereof and any prospective
          purchase of such Transfer Restricted  Securities from
          such Holder or beneficial owner, any information required
          to be supplied to a Holder by Rule 144A(d)(4) under the
          Act in order to permit offers and sales of such Transfer
          Restricted Securities pursuant to Rule 144A.

          SECTION 8. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS

             No Holder may participate in any Underwritten
          Registration hereunder unless such Holder (a) agrees to
          sell such Holder's Transfer Restricted Securities on the
          basis provided in any underwriting arrangements approved
          by the Persons entitled hereunder to approve such
          arrangements and (b) completes and executes all
          reasonable questionnaires, powers of attorney,
          indemnities, underwriting agreements, lock-up letters and
          other documents required under the terms of such
          underwriting arrangements.

          SECTION 9. SELECTION OF UNDERWRITERS

             The Holders of Registrable Securities covered by the
          Registration Statement who desire to do so may sell such
          Registrable Securities in an Underwritten Offering.  In
          any such Underwritten Offering, the investment banker or
          investment bankers and manager or managers that will
          administer the offering will be selected by the Holders
          of a majority in aggregate principal amount or a majority
          of the shares of the Registrable  Securities included in
          such offering; provided that such investment bankers and
          managers must be reasonably satisfactory to the Company.

          SECTION 10. MISCELLANEOUS

              (a)  Remedies.  The Company agrees that monetary
          damages would not be adequate compensation for any loss
          incurred by reason of a breach by it of the provisions of
          this Agreement and hereby agrees to waive the defense in
          any action for specific performance that a remedy at law
          would be adequate.

              (b)  No Inconsistent Agreements.  The Company will
          not, on or after the date of this Agreement, enter into any
          agreement with respect to its securities that is inconsistent 
          with the rights granted to the Holders in this Agreement or
          otherwise conflicts with the provisions hereof.  The
          rights granted to the Holders hereunder are not
          inconsistent with the rights granted to the holders of
          the Company's securities under any agreement in
          effect on the date hereof.

              (c)  Amendments and Waivers.  The provisions of this
          Agreement may not be amended, modified or supplemented,
          and waivers or consents to or departures from the
          provisions hereof may not be given, unless the Company
          has obtained the written consent of Holders of a majority
          of the outstanding principal amount or a majority of the
          shares of Transfer Restricted  Securities.

              (d)  Notices.  All notices and other communications
          provided for or permitted hereunder shall be made in

          benefit of and be binding upon the successors and assigns
          of each of the parties, including without limitation and
          without the need for an express assignment, subsequent

          however, that this Agreement shall not inure to the
          benefit of or be binding upon a successor or assign of a
          Holder unless and to the extent such successor or assign
          acquired Transfer Restricted  Securities from such
          Holder.

                    (f)  Counterparts.  This Agreement may be
          executed in any number of counterparts and by the parties
          hereto in separate counterparts, each of which when so
          executed shall be deemed to be an original and all of
          which taken together shall constitute one and the same
          agreement.

                    (g)  Headings.  The headings in this Agreement
          are for convenience of reference only and shall not limit
          or otherwise affect the meaning hereof.

                    (h)  Governing Law.  THIS AGREEMENT SHALL BE
          GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
          THE STATE OF NEW YORK, WITHOUT REGARD TO THE CONFLICT OF
          LAW RULES THEREOF.

                    (i)  Severability.  In the event that any one
          or more of the provisions contained herein, or the
          application thereof in any circumstance, is held invalid,
          illegal or unenforceable, the validity, legality and
          enforceability of any such provision in every other
          respect and the remaining provisions contained herein
          shall not be affected or impaired thereby.

                    (j)  Entire Agreement.  This Agreement,

          in the Purchase Agreement) and the Merger Agreement, is
          intended by the parties as a final expression of their
          agreement and intended to be a complete and exclusive
          statement of the agreement and understanding of the
          parties hereto in respect of the subject matter contained
          herein.  There are no restrictions, promises, warranties
          or undertakings, other than those set forth or referred
          to herein or therein with respect to the registration
          rights granted by the Company with respect to the
          Transfer Restricted Securities.  This Agreement
          supersedes all prior agreements and understandings
          between the parties with respect to such subject matter.

                          W I T N E S S E T H

               WHEREAS, for its lawful corporate purposes, the Company
     has duly authorized the issuance of its 5 1/2% Senior

     the request of such holder in writing to the Trustee on or before
     the record date preceding any interest payment date, interest on

     available funds.  The term "record date" with respect to any
     interest payment date shall mean the April 15 or October 15

               Interest on the Notes shall be computed on the basis of

     November 1 (herein called "Defaulted Interest") shall forthwith
     cease to be payable to the Noteholder on the relevant record date
     by virtue of his having been such Noteholder; and such Defaulted
     Interest shall be paid by the Company, at its election in each
     case, as provided in clause (1) or (2) below:

               (1)  The Company may elect to make payment of any
     Defaulted Interest to the Persons in whose names the Notes (or
     their respective Predecessor Notes) are registered at the close of
     business on a special record date for the payment of such
     Defaulted Interest, which shall be fixed in the following manner. 
     The Company shall notify the Trustee in writing of the amount of
     Defaulted Interest to be paid on each Note and the date of the
     payment (which shall be not less than 25 days after the receipt by
     the Trustee of such notice, unless the Trustee shall consent to an
     earlier date), and at the same time, the Company shall deposit
     with the Trustee an amount of money equal to the aggregate amount
     to be paid in respect of such Defaulted Interest or shall make
     arrangements satisfactory to the Trustee for such deposit prior to
     the date of the proposed payment, such money when deposited to be
     held in trust for the benefit of the Persons entitled to such
     Defaulted Interest as in this clause provided.  Thereupon, the
     Trustee shall fix a special record date for the payment of such
     Defaulted Interest which shall be not more than 15 days and not
     less than 10 days prior to the date of the payment and not less
     than 10 days after the receipt by the Trustee of the notice of the
     proposed payment.  The Trustee shall promptly notify the Company
     of such special record date and, in the name and at the expense of
     the Company, shall cause notice of the payment of such Defaulted
     Interest and the special record date therefor to be mailed, first-
     class postage prepaid, to each Noteholder at his address as it
     appears in the Note register, not less than 10 days prior to such
     special record date.  Notice of the proposed payment of such
     Defaulted Interest and the special record date therefor having
     been so mailed, such Defaulted Interest shall be paid to the
     Persons in whose names the Notes (or their respective Predecessor
     Notes) were registered at the close of business on such special
     record date and shall no longer be payable pursuant to the
     following clause (2).

               (2)  The Company may make payment of any Defaulted
     Interest in any other lawful manner not inconsistent with the
     requirements of any securities exchange on which the Notes may be
     listed, and upon such notice as may be required by such exchange,
     if, after notice given by the Company to the Trustee of the
     proposed payment pursuant to this clause, such manner of payment
     shall be deemed practicable by the Trustee.

               Section 2.4  Execution of Notes.  The Notes shall be
     signed in the name and on behalf of the Company by the facsimile
     signature of its Chief Executive Officer, President or its Chief
     Financial Officer and attested by the facsimile signature of its
     Secretary or any of its Assistant Secretaries (which may be
     printed, engraved or otherwise reproduced thereon, by facsimile or
     otherwise).  Only such Notes as shall bear thereon a certificate
     of authentication substantially in the form set forth on the forms
     of Notes attached as Exhibits A and B hereto, manually executed by
     the Trustee (or an authenticating agent appointed by the Trustee
     as provided by Section 16.11), shall be entitled to the benefits
     of this Indenture or be valid or obligatory for any purpose.  Such
     certificate by the Trustee (or such an authenticating agent) upon
     any Note executed by the Company shall be conclusive evidence that
     the Note so authenticated has been duly authenticated and
     delivered hereunder and that the holder is entitled to the
     benefits of this Indenture.

               In case any officer of the Company who shall have signed
     any of the Notes shall cease to be such officer before the Notes
     so signed shall have been authenticated and delivered by the
     Trustee, or disposed of by the Company, such Notes nevertheless
     may be authenticated and delivered or disposed of as though the
     person who signed such Notes had not ceased to be such officer of
     the Company; and any Note may be signed on behalf of the Company
     by such persons as, at the actual date of the execution of such
     Note, shall be the proper officers of the Company, although at the
     date of the execution of this Indenture any such person was not
     such an officer.

               Section 2.5  Exchange and Registration of Transfer of
     Notes; Restrictions on Transfer; Depositary.

               (a)  The Company shall cause to be kept at the Corporate

     such office and in any other office or agency of the Company
     designated pursuant to Section 5.2 being herein sometimes
     collectively referred to as the "Note register") in which, subject
     to such reasonable regulations as it may prescribe, the Company
     shall provide for the registration of Notes and of transfers of
     Notes.  Such register shall be in written form or in any form
     capable of being converted into written form within a reasonable
     period of time.  The Trustee is hereby appointed "Note registrar"
     for the purpose of registering Notes and transfers of Notes as

     registrars.

               Upon surrender for registration of transfer of any Note
     to the Note registrar or any co-registrar and satisfaction of the
     requirements for such transfer set forth in this Section 2.5, the
     Company shall execute, and the Trustee shall authenticate and
     deliver, in the name of the designated transferee or transferees,
     one or more new Notes of any authorized denominations and of a
     like aggregate principal amount and bearing such restrictive
     legends as may be required by Section 2.5(d).

               Notes may be exchanged for other Notes of any authorized
     denominations and of a like aggregate principal amount, upon
     surrender of the Notes to be exchanged at any such office or
     agency.  Whenever any Notes are so surrendered for exchange, the
     Company shall execute, and the Trustee shall authenticate and
     deliver, the Notes which the Noteholder making the exchange is
     entitled to receive.

               All Notes presented or surrendered for registration of
     transfer or for exchange shall (if so required by the Company, the
     Trustee, the Note registrar or any co-registrar) be duly endorsed,
     or be accompanied by a written instrument of transfer in form
     satisfactory to the Company, and the Note shall be duly executed
     by the Noteholder thereof or his attorney duly authorized in
     writing.

               No service charge shall be charged to the Noteholder for
     any exchange or registration of transfer of Notes, but the Company
     may require payment of a sum sufficient to cover any tax,
     assessments or other governmental charges that may be imposed in
     connection therewith.

               None of the Company, the Trustee, the Note registrar or
     any co-registrar shall be required to exchange or register a
     transfer of (a) any Notes for a period of 15 days next preceding
     any selection of Notes to be redeemed or (b) any Notes called for
     redemption or, if a portion of any Note is selected or called for
     redemption, such portion thereof selected or called for redemption
     or (c) any Notes surrendered for conversion or exchange in
     accordance with Articles XV or XVII or, if a portion of any Note
     is surrendered for conversion or such exchange, such portion
     thereof surrendered for conversion or exchange or (d) any Notes
     surrendered for redemption pursuant to Section 3.5 or, if a
     portion of any Note is surrendered for redemption pursuant to
     Section 3.5, such portion thereof surrendered for redemption
     pursuant to Section 3.5.

               All Notes issued upon any transfer or exchange of Notes
     shall be the valid obligations of the Company, evidencing the same
     debt, and entitled to the same benefits under this Indenture as
     the Notes surrendered upon such registration of transfer or
     exchange.

               (b)  So long as the Notes are eligible for book-entry
     settlement with the Depositary, or unless otherwise required by
     law, all Notes to be traded on the PORTAL Market shall be
     represented by a Note in global form registered in the name of the
     Depositary or the nominee of the Depositary.  The transfer and
     exchange of beneficial interests in such Note in global form,
     which does not involve the issuance of a definitive Note, shall be
     effected through the Depositary (but not the Trustee or the
     Custodian) in accordance with this Indenture (including the
     restrictions on transfer set forth herein) and the procedures of
     the Depositary therefor.  Neither the Trustee nor the Custodian
     (in such respective capacities) will have any responsibility for
     the transfer and exchange of beneficial interests in such Note in
     global form that does not involve the issuance of a definitive
     Note.

               At any time at the request of the beneficial holder of
     an interest in a Note in global form, such beneficial holder shall
     be entitled to obtain a definitive Note upon written request to
     the Trustee and the Custodian in accordance with the standing
     instructions and procedures existing between the Depositary and
     the Custodian for the issuance thereof.  Upon receipt of any such
     request, the Trustee or the Custodian, at the direction of the
     Trustee, will cause, in accordance with the standing instructions
     and procedures existing between the Depositary and the Custodian,
     the aggregate principal amount of the Note in global form to be
     reduced and, following such reduction, the Company will execute
     and the Trustee will authenticate and deliver to such beneficial
     holder (or its nominee) a Note or Notes in the appropriate
     aggregate principal amount in the name of such beneficial holder
     (or its nominee) and bearing such restrictive legends as may be
     required by this Indenture.

               Any transfer of a beneficial interest in a Note in
     global form which cannot be effected through book-entry settlement
     must be effected by the delivery to the transferee (or its
     nominee) of a definitive Note or Notes registered in the name of
     the transferee (or its nominee) on the books maintained by the
     Trustee.  With respect to any such transfer, the Trustee or the
     Custodian, at the direction of the Trustee, will cause, in
     accordance with the standing instructions and procedures existing
     between the Depositary and the Custodian, the aggregate principal
     amount of the Note in global form to be reduced and, following
     such reduction, the Company will execute and the Trustee will
     authenticate and deliver to the transferee (or such transferee's
     nominee, as the case may be), a Note or Notes in the appropriate
     aggregate principal amount in the name of such transferee (or its
     nominee) and bearing such restrictive legends as may be required
     by this Indenture.  In connection with any such transfer, the
     Trustee or the Custodian, at the direction of the Trustee, may
     request such representations and agreements relating to the
     restrictions on transfer of such Note or Notes from such
     transferee (or such transferee's nominee) as may be required under
     this Indenture or as the Company may direct the Trustee to
     request.

               (c)  So long as the Notes are eligible for book-entry
     settlement, or unless otherwise required by law, upon any transfer
     of a definitive Note to a QIB in accordance with Rule 144A, unless
     otherwise requested by the transferor, and upon receipt of the
     definitive Note or Notes being so transferred, together with a
     certification from the transferor that the transferee is a QIB (or
     other evidence satisfactory to the Trustee), the Trustee shall
     direct the Custodian to adjust its records with respect to the
     Note in global form to reflect an increase in the aggregate
     principal amount of the Notes represented by the Note in global
     form, the Trustee shall cancel such definitive Note or Notes and
     cause, or direct the Custodian to cause, in accordance with the
     standing instructions and procedures existing between the
     Depositary and the Custodian, the aggregate principal amount of
     Notes represented by the Note in global form to be increased
     accordingly.

               Any Note in global form may be endorsed with or have
     incorporated in the text thereof such legends or recitals or
     changes not inconsistent with the provisions of this Indenture as
     may be required by the Custodian, the Depositary or by the
     National Association of Securities Dealers, Inc. in order for the
     Notes to be tradeable on the PORTAL Market or as may be required
     for the Notes to be tradeable on any other market developed for
     trading of securities pursuant to Rule 144A or required to comply
     with any applicable law or any regulation thereunder or with the
     rules and regulations of any securities exchange upon which the
     Notes may be listed or traded or to conform with any usage with
     respect thereto, or to indicate any special limitations or
     restrictions to which any particular Notes are subject.

               (d)  Every Note that bears or is required under this
     Section 2.5(d) to bear the legend set forth in this Section 2.5(d)
     (together with Preferred Stock issued upon exchange for all or a
     portion of such Note or any Common Stock issued upon conversion of
     the Notes and required to bear the legend set forth in Section
     2.5(e), collectively, the "Restricted Securities") shall be
     subject to the restrictions on transfer set forth in this Section
     2.5(d), unless such restrictions on transfer shall have been
     waived by the written consent of the Company or removed in
     accordance with the provisions of Section 2.5(f), and the holder
     of each such Restricted Security, by such holder's acceptance
     thereof, agrees to be bound by such restrictions on transfer.  As
     used in this Section 2.5(d), the term "transfer" encompasses any
     sale, pledge, transfer or other disposition of any Restricted
     Security.

               Until three years after the later of the original
     issuance date of any Note and the last date on which the Company
     or an Affiliate of the Company was the owner of such Note, any
     certificate evidencing such Note (and all securities issued in
     exchange therefor or substitution thereof, other than Preferred
     Stock, if any, issued in exchange therefor or Common Stock, if
     any, issued upon conversion thereof, which shall bear the legend
     set forth in Section 2.5(e), if applicable) shall bear a legend in
     substantially the following form, unless otherwise agreed by the
     Company (with notice thereof to the Trustee):

               THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER
               THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE
               "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS, AND MAY
               NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO,
               OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS
               SET FORTH IN THE FOLLOWING SENTENCE.  BY ACQUISITION
               HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A
               "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A
               UNDER THE SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL
               "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1),
               (2), (3) OR (7) UNDER THE SECURITIES ACT)
               ("INSTITUTIONAL ACCREDITED INVESTOR") OR (C) IT IS NOT A
               U.S. PERSON AND IS ACQUIRING THE NOTE EVIDENCED HEREBY
               IN AN OFFSHORE TRANSACTION; (2) AGREES THAT IT WILL NOT
               PRIOR TO THE DATE THAT IS THREE YEARS AFTER THE LATER OF
               THE ORIGINAL ISSUANCE OF THE NOTE EVIDENCED HEREBY AND
               THE LAST DATE ON WHICH SOFTKEY INTERNATIONAL INC. (THE
               "COMPANY") OR ANY "AFFILIATE" (AS DEFINED IN RULE 144
               UNDER THE SECURITIES ACT) OF THE COMPANY WAS THE OWNER
               OF THE NOTE (THE "RESTRICTION TERMINATION DATE") RESELL
               OR OTHERWISE TRANSFER THE NOTE EVIDENCED HEREBY OR THE
               PREFERRED STOCK ISSUED UPON EXCHANGE OF SUCH NOTE OR THE
               COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH NOTE
               EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B)
               TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH
               RULE 144A UNDER THE SECURITIES ACT, (C) TO AN
               INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH
               TRANSFER, FURNISHES TO STATE STREET BANK AND TRUST
               COMPANY, AS TRUSTEE, A SIGNED LETTER CONTAINING CERTAIN
               REPRESENTATIONS AND AGREEMENTS RELATING TO THE
               RESTRICTIONS ON TRANSFER OF THE NOTE EVIDENCED HEREBY
               (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH
               TRUSTEE), (D) OUTSIDE THE UNITED STATES IN COMPLIANCE
               WITH RULE 904 UNDER THE SECURITIES ACT OR (E) PURSUANT
               TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144
               UNDER THE SECURITIES ACT (IF AVAILABLE); AND (3) AGREES
               THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE NOTE
               EVIDENCED HEREBY IS TRANSFERRED A NOTICE SUBSTANTIALLY
               TO THE EFFECT OF THIS LEGEND.  IN CONNECTION WITH ANY
               TRANSFER OF THE NOTE EVIDENCED HEREBY BEFORE THE
               RESTRICTION TERMINATION DATE, THE HOLDER MUST CHECK THE
               APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING
               TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS
               CERTIFICATE TO STATE STREET BANK AND TRUST COMPANY, AS
               TRUSTEE.  IF THE PROPOSED TRANSFER IS PURSUANT TO CLAUSE
               (C), (D) OR (E) ABOVE, THE HOLDER MUST, PRIOR TO SUCH
               TRANSFER, FURNISH TO STATE STREET BANK AND TRUST
               COMPANY, AS TRUSTEE, SUCH CERTIFICATIONS, LEGAL OPINIONS
               OR OTHER INFORMATION AS THE COMPANY MAY REASONABLY
               REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE
               PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT
               SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
               SECURITIES ACT.  THIS LEGEND WILL BE REMOVED UPON THE
               RESTRICTION TERMINATION DATE.  AS USED HEREIN, THE TERMS
               "OFFSHORE TRANSACTION," "UNITED STATES" AND "U.S.
               PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S
               UNDER THE SECURITIES ACT.

               Any Note (or security issued in exchange or substitution
     therefor) as to which such restrictions on transfer shall have
     expired in accordance with their terms may, upon satisfaction of
     the requirements of Section 2.5(f) and surrender of such Note for
     exchange to the Note registrar in accordance with the provisions
     of this Section 2.5, be exchanged for a new Note or Notes, of like
     tenor and aggregate principal amount, which shall not bear the
     restrictive legend required by this Section 2.5(d).

               Notwithstanding any other provisions of this Indenture
     (other than the provisions set forth in this Section 2.5(d)), a
     Note in global form may not be transferred as a whole except by
     the Depositary to a nominee of the Depositary or by a nominee of
     the Depositary to the Depositary or another nominee of the
     Depositary or by the Depositary or any such nominee to a successor
     Depositary or a nominee of such successor Depositary.

               The Depositary shall be a clearing agency registered
     under the Exchange Act.  The Company initially appoints The
     Depository Trust Company to act as Depositary with respect to the
     Notes in global form.  Initially, the global Note shall be issued
     to the Depositary, registered in the name of Cede & Co., as the
     nominee of the Depositary, and deposited with the Trustee as
     Custodian for Cede & Co.

               If at any time the Depositary for the Note in global
     form notifies the Company that it is unwilling or unable to
     continue as Depositary for such Note, the Company may appoint a
     successor Depositary with respect to such Note.  If a successor
     Depositary for the Note is not appointed by the Company within 90
     days after the Company receives such notice, the Company will
     execute, and the Trustee, upon receipt of an Officers' Certificate
     for the authentication and delivery of Notes, will authenticate
     and deliver, Notes in definitive form, in an aggregate principal
     amount equal to the principal amount of the Note in global form,
     in exchange for such Note in global form.

               Definitive Notes issued in exchange for all or a part of
     a Note in global form pursuant to this Section 2.5(d) shall be
     registered in such names and in such authorized denominations as
     the Depositary, pursuant to instructions from its direct or
     indirect participants or otherwise, shall instruct the Trustee. 
     Upon execution and authentication, the Trustee shall deliver such
     definitive Notes to the persons in whose names such definitive
     Notes are so registered.

               At such time as all interests in a Note in global form
     have been redeemed, converted, repurchased or canceled, such Note
     in global form shall be, upon receipt thereof, canceled by the
     Trustee in accordance with standing procedures and instructions
     existing between the Depositary and the Custodian.  At any time
     prior to such cancellation, if any interest in a global Note is
     exchanged for definitive Notes, redeemed, converted, canceled or
     transferred to a transferee who receives definitive Notes therefor
     or any definitive Note is exchanged or transferred for part of a
     Note in global form, the principal amount of such Note in global
     form shall, in accordance with the standing procedures and
     instructions existing between the Depositary and the Custodian, be
     reduced or increased, as the case may be, and an adjustment shall
     be made on the records of the Trustee with respect to such Note in
     global form by the Trustee or the Custodian, at the direction of
     the Trustee, to reflect such reduction or increase.

               (e)  Until three years after the later of the original
     issuance date of any Note and the last date on which the Company
     or an Affiliate of the Company was the owner of such Note, any
     stock certificate representing Preferred Stock issued upon
     exchange of such Note or Common Stock issued upon conversion of
     such Note shall bear a legend in substantially the following form,
     including the bracketed material as appropriate, unless otherwise
     agreed by the Company (with written notice thereof to the Trustee
     and any transfer agent for the Common Stock):

               THE [COMMON][PREFERRED] STOCK EVIDENCED HEREBY HAS NOT
               BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933,
               AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE
               SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD WITHIN
               THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT
               OF U.S. PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING
               SENTENCE. THE HOLDER HEREOF AGREES THAT PRIOR TO THE
               DATE THAT IS THREE YEARS AFTER THE LATER OF THE ORIGINAL
               ISSUANCE OF THE NOTE UPON THE [CONVERSION OF WHICH THE
               COMMON STOCK] [EXCHANGE FOR WHICH THE PREFERRED STOCK]
               EVIDENCED HEREBY WAS ISSUED AND THE LAST DATE ON WHICH
               SOFTKEY INTERNATIONAL INC. (THE "COMPANY") OR ANY
               "AFFILIATE" (AS DEFINED IN RULE 144 OF THE SECURITIES
               ACT) OF THE COMPANY WAS THE OWNER OF THE NOTE UPON THE
               [CONVERSION OF] [EXCHANGE FOR] WHICH THE [COMMON
               STOCK][PREFERRED STOCK] EVIDENCED HEREBY WAS ISSUED (THE
               "RESTRICTION TERMINATION DATE"), (1) IT WILL NOT RESELL
               OR OTHERWISE TRANSFER THE [COMMON STOCK] [PREFERRED
               STOCK] EVIDENCED HEREBY EXCEPT (A) TO THE COMPANY OR ANY
               SUBSIDIARY THEREOF, (B) TO A "QUALIFIED INSTITUTIONAL
               BUYER" IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES
               ACT, (C) TO AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS
               DEFINED IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE
               SECURITIES ACT) THAT PRIOR TO SUCH TRANSFER, FURNISHES
               TO THE FIRST NATIONAL BANK OF BOSTON, AS TRANSFER AGENT,
               A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
               AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF
               THE [COMMON STOCK] [PREFERRED STOCK] EVIDENCED HEREBY
               (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH
               TRANSFER AGENT), (D) OUTSIDE THE UNITED STATES IN
               COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (E)
               PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY
               RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), OR (F)
               PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN
               DECLARED EFFECTIVE UNDER THE SECURITIES ACT; (2) PRIOR
               TO ANY SUCH TRANSFER PURSUANT TO CLAUSE (C), (D) OR (E)
               ABOVE, IT WILL FURNISH TO THE FIRST NATIONAL BANK OF
               BOSTON, AS TRANSFER AGENT, SUCH CERTIFICATIONS, LEGAL
               OPINIONS OR OTHER INFORMATION AS THE COMPANY MAY
               REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS
               BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A
               TRANSACTION NOT SUBJECT TO, THE REGISTRATION
               REQUIREMENTS OF THE SECURITIES ACT; AND (3) IT WILL
               DELIVER TO EACH PERSON TO WHOM THE [COMMON
               STOCK][PREFERRED STOCK] EVIDENCED HEREBY IS TRANSFERRED
               A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. 
               THIS LEGEND WILL BE REMOVED UPON THE RESTRICTION
               TERMINATION DATE.  AS USED HEREIN, THE TERMS "UNITED
               STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO
               THEM BY REGULATION S UNDER THE SECURITIES ACT.

               Any such Preferred Stock or Common Stock as to which
     such restrictions on transfer shall have expired in accordance
     with their terms may, upon satisfaction of the requirements of
     Section 2.5(f) and surrender of the certificates representing such
     shares of Preferred Stock or Common Stock for exchange in
     accordance with the procedures of the transfer agent for the
     Common Stock or the Preferred Stock, as the case may be, be
     exchanged for a new certificate or certificates for a like
     aggregate number of shares of Preferred Stock or Common Stock, as
     the case may be, which shall not bear the restrictive legend
     required by this Section 2.5(e).  

               (f)  Upon any sale or transfer of any Restricted
     Security (including any interest in a Note in global form) (i)
     that is effected pursuant to an effective registration statement
     under the Securities Act, (ii) that is effected pursuant to Rule
     144 as promulgated under the Securities Act or (iii) in connection
     with which the Trustee (or transfer agent for the Common Stock, in
     the case of shares of Common Stock of the Company or any transfer
     agent for the Preferred Stock in the case of shares of Preferred
     Stock) receives certificates and other information (including an
     Opinion of Counsel, if requested) reasonably acceptable to the
     Company and the Trustee (or such transfer agent, as the case may
     be) to the effect that such security will no longer be subject to
     the resale restrictions under federal and state securities laws,
     then (A) in the case of a Restricted Security in definitive form,
     the Note registrar or co-registrar (or transfer agent, in the case
     of Common stock of the Company or any transfer agent for the
     Preferred Stock in the case of shares of Preferred Stock) shall
     permit the holder thereof to exchange such Restricted Security for
     a security that does not bear the legends set forth in Section
     2.5(d) or 2.5(e), as applicable, and shall rescind any such
     restrictions on transfer and (B) in the case of Restricted
     Securities represented by a Note in global form, such Note shall
     no longer be subject to the restrictions contained in the legend
     set forth in Section 2.5(d) (but still subject to the other
     provisions hereof).  In addition, any Note (or security issued in
     exchange or substitution therefor) or shares of Preferred Stock
     issued upon exchange of any Note or shares of Common Stock issued
     upon conversion of any Note, in any case, as to which the
     restrictions on transfer described in the legends set forth in
     Section 2.5(d) and 2.5(e), respectively, have expired by their
     terms, may, upon surrender thereof (in accordance with the terms
     of this Indenture in the case of Notes) together with such
     certifications and other information (including an Opinion of
     Counsel having substantial experience in practice under the
     Securities Act and otherwise reasonably acceptable to the Company,
     addressed to the Company and the Trustee and in a form acceptable
     to the Company, to the effect that the transfer of such Restricted
     Security has been made in compliance with Rule 144 or such
     successor provision) acceptable to the Company and the Trustee (or
     any transfer agent, as the case may be) as either of them may
     reasonably require, be exchanged for a new Note or Notes of like
     tenor and aggregate principal amount (in the case of Notes), or a
     new certificate or certificates for a like aggregate number of
     shares of Preferred Stock (in the case of Preferred Stock) or
     Common Stock (in the case of Common Stock), or a new certificate
     or other instrument of like tenor and amount (in the case of
     securities issued in exchange or substitution for Notes), which
     shall not bear the restrictive legends set forth in Sections
     2.5(d) and 2.5(e).

               (g)  The form of representation letter referred to in
     the restrictive legends in Sections 2.5(d) and 2.5(e) hereof is
     attached hereto as Exhibit D.

               Section 2.6  Mutilated, Destroyed, Lost or Stolen Notes. 
     In case any Note shall become mutilated or be destroyed, lost or
     stolen, the Company in its discretion may execute, and upon its
     request, the Trustee or an authenticating agent appointed by the
     Trustee shall authenticate and deliver, a new Note, bearing a
     number not contemporaneously outstanding, in exchange and
     substitution for the mutilated Note, or in lieu of and in
     substitution for the Note so destroyed, lost or stolen.  The
     Company may charge such applicant for the expenses of the Company
     in replacing a Note.  In every case the applicant for a
     substituted Note shall furnish to the Company, to the Trustee and,
     if applicable, to such authenticating agent such security or
     indemnity as may be required by them to save each of them harmless
     from any loss, liability, cost or expense caused by or connected
     with such substitution, and in every case of destruction, loss or
     theft, the applicant shall also furnish to the Company, to the
     Trustee and, if applicable, to such authenticating agent evidence
     to their satisfaction of the destruction, loss or theft of such
     Note and of the ownership thereof.

               The Trustee or such authenticating agent may
     authenticate any such substituted Note and deliver the same upon
     the receipt of such security or indemnity as the Trustee, the
     Company and, if applicable, such authenticating agent may require.
     Upon the issuance of any substituted Note, the Company may require
     the payment of a sum sufficient to cover any tax or other
     governmental charge that may be imposed in relation thereto and
     any other expenses connected therewith.  In case any Note which
     has matured or is about to mature or has been called for
     redemption or is about to be converted into Common Stock shall
     become mutilated or be destroyed, lost or stolen, the Company may,
     instead of issuing a substitute Note, pay or authorize the payment
     of or convert or authorize the conversion of the same (without
     surrender thereof, except in the case of a mutilated Note), as the
     case may be, if the applicant for such payment or conversion shall
     furnish to the Company, to the Trustee and, if applicable, to such
     authenticating agent such security or indemnity as may be required
     by them to save each of them harmless from any loss, liability,
     cost or expense caused by or connected with such substitution, and
     in case of destruction, loss or theft, evidence satisfactory to
     the Company, the Trustee and, if applicable, any paying agent or
     conversion agent of the destruction, loss or theft of such Note
     and of the ownership thereof.

               Every substitute Note issued pursuant to the provisions
     of this Section 2.6 in lieu of any Note which is destroyed, lost
     or stolen shall constitute an additional contractual obligation of
     the Company, whether or not the destroyed, lost or stolen Note
     shall be enforceable by anyone, and shall be entitled to all the
     benefits (but shall be subject to all the limitations set forth
     in) this Indenture equally and proportionately with any and all
     other Notes duly issued hereunder.  To the extent permitted by
     law, all Notes shall be held and owned upon the express condition
     that the foregoing provisions are exclusive with respect to the
     replacement or payment or conversion of mutilated, destroyed, lost
     or stolen Notes and shall preclude any and all other rights or
     remedies notwithstanding any law or statute existing or hereafter
     enacted to the contrary with respect to the replacement or payment
     or conversion of negotiable instruments or other securities
     without their surrender.

               Section 2.7  Temporary Notes.  Pending the preparation
     of definitive Notes, the Company may execute and the Trustee or an
     authenticating agent appointed by the Trustee shall, upon written
     request of the Company, authenticate and deliver temporary Notes
     (printed or lithographed).  Temporary Notes shall be issuable in
     any authorized denomination and shall be substantially in the form
     of the definitive Notes but with such omissions, insertions and
     variations as may be appropriate for temporary Notes, all as may
     be determined by the Company.  Every such temporary Note shall be
     executed by the Company and authenticated by the Trustee or such
     authenticating agent upon the same conditions and in substantially
     the same manner, and with the same effect, as the definitive
     Notes.  Without unreasonable delay the Company will execute and
     deliver to the Trustee or such authenticating agent definitive
     Notes (other than in the case of Notes in global form) and
     thereupon any or all temporary Notes (other than any such Note in
     global form) may be surrendered in exchange therefor, at each
     office or agency maintained by the Company pursuant to Section 5.2
     and the Trustee or such authenticating agent shall authenticate
     and deliver in exchange for such temporary Notes an equal
     aggregate principal amount of definitive Notes.  Such exchange
     shall be made by the Company at its own expense and without any
     charge therefor.  Until so exchanged, the temporary Notes shall in
     all respects be entitled to the same benefits and subject to the
     same limitations under this Indenture as definitive Notes
     authenticated and delivered hereunder.

               Section 2.8  Cancellation of Notes Paid, Etc.  All Notes
     surrendered for the purpose of payment, redemption, conversion,
     exchange or registration of transfer shall, if surrendered to the
     Company or any paying agent or any Note registrar or any
     conversion agent, be surrendered to the Trustee and promptly
     canceled by it or, if surrendered to the Trustee, shall be
     promptly canceled by it and no Notes shall be issued in lieu
     thereof except as expressly permitted by any of the provisions of
     this Indenture.  Upon written instructions of the Company, the
     Trustee shall destroy canceled Notes, in accordance with the usual
     destruction procedures of the Trustee.  If the Company shall
     acquire any of the Notes, such acquisition shall not operate as a
     redemption or satisfaction of the indebtedness represented by such
     Notes unless and until the same are delivered to the Trustee for
     cancellation.

               Section 2.9  Ranking.  The Notes will represent general,
     unsecured obligations of the Company senior or pari passu in right
     of payment to all other unsecured obligations of the Company and
     will rank pari passu in order of preference with the Company's 5
     1/2% Senior Convertible Notes due 2000 issued October 23, 1995.

                               ARTICLE III
  
                            REDEMPTION OF NOTES

               Section 3.1  Redemption Prices.  The Company may, at its
     option, redeem all or from time to time any part of the Notes on
     any date prior to maturity, upon notice as set forth in Section
     3.2, and at the optional redemption prices set forth in the forms
     of Note attached as Exhibits A and B hereto, together with accrued
     interest to the date fixed for redemption, provided, however, that
     no such redemption shall be effected before November 2, 1998.

               Section 3.2  Notice of Redemption, Selection of Notes. 
     In case the Company shall desire to exercise the right to redeem
     all or, as the case may be, any part of the Notes pursuant to
     Section 3.1, it shall fix a date for redemption and, in the case
     of any redemption pursuant to Section 3.1, it or, at its request
     accompanied by the proposed form of notice of redemption (which
     must be received by the Trustee at least ten Business Days prior
     to the date the Trustee is requested to give notice as described
     below, unless a shorter period is agreed to by the Trustee), the
     Trustee in the name of and at the expense of the Company, shall
     mail or cause to be mailed a notice of such redemption at least 30
     and not more than 60 days prior to the date fixed for redemption
     to the holders of Notes so to be redeemed in whole or in part at
     their last addresses as the same appear on the Note register,
     provided that if the Company shall give such notice, it shall also
     give such notice, and notice of the Notes to be redeemed, to the
     Trustee.  Such mailing shall be by first class mail.  The notice,
     if mailed in the manner herein provided, shall be conclusively
     presumed to have been duly given, whether or not the holder
     receives such notice.  In any case, failure to give such notice by
     mail or any defect in the notice to the holder of any Note
     designated for redemption as a whole or in part shall not affect
     the validity of the proceedings for the redemption of any other
     Note.

               Each such notice of redemption shall specify the
     aggregate principal amount of Notes to be redeemed, the date fixed
     for redemption, the redemption price at which Notes are to be
     redeemed, the place or places of payment, that payment will be
     made upon presentation and surrender of such Notes, that interest
     accrued to the date fixed for redemption will be paid as specified
     in said notice and that on and after said date, interest thereon
     or on the portion thereof to be redeemed will cease to accrue. 
     Such notice shall also state the current Exchange Price and
     Conversion Price and the date on which the right to exchange and
     to convert such Notes or portions thereof into Preferred Stock or
     Common Stock, as the case may be, will expire.  If fewer than all
     the Notes are to be redeemed, the notice of redemption shall
     identify the Notes to be redeemed.  In case any Note is to be
     redeemed in part only, the notice of redemption shall state the
     portion of the principal amount thereof to be redeemed and shall
     state that on and after the date fixed for redemption, upon
     surrender of such Note, a new Note or Notes in principal amount
     equal to the unredeemed portion thereof will be issued.

               On or prior to the Business Day prior to the redemption
     date specified in the notice of redemption given as provided in
     this Section, the Company will deposit with the Trustee or with
     one or more paying agents (or, if the Company is acting as its own
     paying agent, set aside, segregate and hold in trust as provided
     in Section 5.4) an amount of money sufficient to redeem on the
     redemption date all the Notes so called for redemption (other than
     those theretofore surrendered for exchange for Preferred Stock or
     conversion into Common Stock) at the appropriate redemption price,
     together with accrued interest to the date fixed for redemption.
     If any Note called for redemption is exchanged or converted
     pursuant hereto, any money deposited with the Trustee or any
     paying agent or so segregated and held in trust for the redemption
     of such Note shall be paid to the Company upon its request or, if
     then held by the Company, shall be discharged from such trust. If
     fewer than all the Notes are to be redeemed, the Company will give
     the Trustee written notice in the form of an Officers' Certificate
     (accompanied by the proposed form of notice of redemption) not
     fewer than 45 days (or such shorter period of time as may be
     acceptable to the Trustee) prior to the redemption date as to the
     aggregate principal amount of Notes to be redeemed.

               If fewer than all the Notes are to be redeemed, the
     Trustee shall select the Notes or portions thereof to be redeemed
     (in principal amounts of $1,000 or integral multiples thereof), by
     lot or, in its sole discretion, on a pro rata basis.  If any Note
     selected for partial redemption is exchanged or converted in part
     after such selection, the converted or exchanged portion of such
     Note shall be deemed (so far as may be) to be the portion to be
     selected for redemption.  The Notes (or portions thereof) so
     selected shall be deemed duly selected for redemption for all
     purposes hereof, notwithstanding that any such Note is exchanged
     or converted as a whole or in part before the mailing of the
     notice of redemption.

               Upon any redemption of less than all Notes, the Company
     and the Trustee may treat as outstanding any Notes surrendered for
     exchange or conversion during the period of 15 days next preceding
     the mailing of a notice of redemption and need not treat as
     outstanding any Note authenticated and delivered during such
     period in exchange for the unexchanged or unconverted portion of
     any Note exchanged or converted in part during such period. 

               Section 3.3  Payment of Notes Called for Redemption.  If
     notice of redemption has been given as above provided, the Notes
     or portion of Notes with respect to which such notice has been
     given shall, unless exchanged for Preferred Stock or converted
     into Common Stock pursuant to the terms hereof, become due and
     payable on the date and at the place or places stated in such
     notice at the applicable redemption price, together with interest
     thereon accrued to the date fixed for redemption, and on and after
     said date (unless the Company shall default in the payment of such
     Notes at the redemption price, together with interest thereon
     accrued to said date), interest on the Notes or portion of Notes
     so called for redemption shall cease to accrue, and such Notes
     shall cease after the close of business on the Business Day next
     preceding the date fixed for redemption to be exchangeable for
     Preferred Stock or convertible into Common Stock and, except as
     provided in Sections 8.5 and 13.4, to be entitled to any benefit
     or security under this Indenture, and the holders thereof shall
     have no right in respect of such Notes except the right to receive
     the redemption price thereof and unpaid interest thereon to the
     date fixed for redemption.  On presentation and surrender of such
     Notes at a place of payment in said notice specified, the said
     Notes or the specified portions thereof shall be paid and redeemed
     by the Company at the applicable redemption price, together with
     interest accrued thereon to the date fixed for redemption;
     provided that any semi-annual payment of interest becoming due on
     the date fixed for redemption shall be payable to the holders of
     such Notes registered as such on the relevant record date subject
     to the terms and provisions of Section 2.3 hereof.

               Upon presentation of any Note redeemed in part only, the
     Company shall execute and the Trustee shall authenticate and
     deliver to the holder thereof, at the expense of the Company, a
     new Note or Notes, of authorized denominations, in principal
     amount equal to the unredeemed portion of the Notes so presented.

               Notwithstanding the foregoing, the Trustee shall not
     redeem any Notes or mail any notice of optional redemption during
     the continuance of a default in payment of interest or premium on
     the Notes or of any Event of Default of which, in the case of any
     Event of Default other than under Section 7.1(a) or (b), a
     Responsible Officer of the Trustee has knowledge.  If any Note
     called for redemption shall not be so paid upon surrender thereof
     for redemption, the principal and premium, if any, shall, until
     paid or duly provided for, bear interest from the date fixed for
     redemption at the rate borne by the Note and such Note shall
     remain exchangeable for Preferred Stock and convertible into
     Common Stock until the principal and premium, if any, shall have
     been paid or duly provided for.

               Section 3.4  Conversion/Exchange Arrangement on Call for
     Redemption.  In connection with any redemption of Notes, the
     Company may arrange for the purchase and conversion or exchange of
     any Notes by an agreement with one or more investment bankers or
     other purchasers to purchase such Notes by paying to the Trustee
     in trust for the Noteholders, on or before the date fixed for
     redemption, an amount not less than the applicable redemption
     price, together with interest accrued to the date fixed for
     redemption, of such Notes.  Notwithstanding anything to the
     contrary contained in this Article III, the obligation of the
     Company to pay the redemption price of such Notes, together with
     interest accrued to the date fixed for redemption, shall be deemed
     to be satisfied and discharged to the extent such amount is so
     paid by such purchasers.  If such an agreement is entered into, a
     copy of which will be filed with the Trustee at least two Business
     Days prior to the date fixed for redemption, any Notes not duly
     surrendered for conversion or exchange by the holders thereof may,
     at the option of the Company, be deemed, to the fullest extent
     permitted by law, acquired by such purchasers from such holders
     and (notwithstanding anything to the contrary contained in
     Articles XV or XVII) surrendered by such purchasers for conversion
     or exchange, all as of immediately prior to the close of business
     on the date fixed for redemption (and the right to exchange or
     convert any such Notes shall be deemed to have been extended
     through such time), subject to payment of the above amount as
     aforesaid.  At the direction of the Company, the Trustee shall
     hold and dispose of any such amount paid to it in the same manner
     as it would monies deposited with it by the Company for the
     redemption of Notes.  Without the Trustee's prior written consent,
     no arrangement between the Company and such purchasers for the
     purchase and conversion or exchange of any Notes shall increase or
     otherwise affect any of the powers, duties, responsibilities or
     obligations of the Trustee as set forth in this Indenture, and the
     Company agrees to indemnify the Trustee from, and hold it harmless
     against, any loss, liability or expense arising out of or in
     connection with any such arrangement for the purchase and
     conversion or exchange of any Notes between the Company and such
     purchasers including the costs and expenses incurred by the
     Trustee in the defense of any claim or liability arising out of or
     in connection with the exercise or performance of any of its
     powers, duties, responsibilities or obligations under this
     Indenture.

               Section 3.5  Purchase of Notes Upon a Change of Control.

               (a)  If a Change of Control shall occur at any time,
     then each holder of Notes shall have the right to require that the
     Company purchase such holder's Notes in whole or in part in
     integral multiples of $1,000 at a purchase price (the "Change of
     Control Purchase Price") in cash in an amount equal to 101% of the
     principal amount of such Notes, plus accrued and unpaid interest
     thereon, if any, to the repurchase date (the "Change of Control
     Purchase Date") pursuant to the offer described below (the "Change
     of Control Offer") and in accordance with the other procedures set
     forth in this Indenture.

               (b)  Within 30 days following any Change of Control, the
     Company shall notify the Trustee thereof and give written notice
     of such Change of Control to each holder of Notes, by first-class
     mail, postage prepaid, at his address appearing in the Note
     register, stating, among other things: that a Change of Control
     has occurred; the Change of Control Purchase Price and the Change
     of Control Purchase Date (which shall be a Business Day no earlier
     than 30 days nor later than 60 days from the date such notice is
     mailed, or such later date as is necessary to comply with
     requirements under the Exchange Act); that any Note not tendered
     will continue to accrue interest and to have all of the benefits
     of this Indenture; that, unless the Company defaults in the
     payment of the Change of Control Purchase Price, any Notes
     accepted for payment pursuant to the Change of Control Offer shall
     cease to accrue interest after the Change of Control Purchase
     Date; and certain other procedures that a holder of Notes must
     follow to accept a Change of Control Offer or to withdraw such
     acceptance.

               (c)  The Company will comply with the applicable tender
     offer rules, including Rule 13e-4 under the Exchange Act, and any
     other applicable securities laws or regulations in connection with
     a Change of Control Offer.

               (d)  The Company will not, and will not permit any
     subsidiary to, create or permit to exist or become effective any
     restriction that would materially impair the ability of the
     Company to make a Change of Control Offer to purchase the Notes
     or, if such Change of Control Offer is made, to pay for the Notes
     tendered for purchase.

                               ARTICLE IV

                               [RESERVED]

                                ARTICLE V

                    PARTICULAR COVENANTS OF THE COMPANY

               Section 5.1  Payment of Principal, Premium and Interest. 
     The Company covenants and agrees that it will duly and punctually
     pay or cause to be paid the principal of and premium, if any, and
     interest on each of the Notes at the places, at the respective
     times and in the manner provided herein and in the Notes.  Each
     installment of interest on the Notes due on any May 1 or November
     1 may be paid by mailing checks for the interest payable to or
     upon the written order of the holders of Notes entitled thereto as
     they shall appear on the Note register; provided that, with
     respect to any holder of Notes with an aggregate principal amount
     equal to or in excess of $5,000,000, at the request of such holder
     in writing to the Trustee, interest on such holder's Notes shall
     be paid by wire transfer in immediately available funds.  An
     installment of principal or interest shall be considered paid on
     the date due if the Trustee or Paying Agent (other than the
     Company, a Subsidiary of the Company or any Affiliate of any of
     them) holds on that date money designated for and sufficient to
     pay the installment of principal or interest and is not prohibited
     from paying such money to the holders of the Notes pursuant to the
     terms of this Indenture.

               Section 5.2  Maintenance of Office or Agency.  The
     Company will maintain in the Borough of Manhattan, The City of New
     York, an office or agency where the Notes may be surrendered for
     registration of transfer or exchange or for presentation for
     payment or for exchange or conversion or redemption and where
     notices and demands to or upon the Company in respect of the Notes
     and this Indenture may be served.  The Company will give prompt
     written notice to the Trustee of the location, and any change in
     the location, of such office or agency not designated by the
     Trustee.  If at any time the Company shall fail to maintain any
     such office or agency or shall fail to furnish the Trustee with
     the address thereof, such presentations, surrenders, notices and
     demands may be made or served at the Corporate Trust office of the
     Trustee.

               The Company may also from time to time designate one or
     more other offices or agencies where the Notes may be presented or
     surrendered for any or all such purposes and may from time to time
     rescind such designations; provided that no such designation or
     rescission shall in any manner relieve the Company of its
     obligation to maintain an office or agency in the Borough of
     Manhattan, The City of New York, for such purposes.  The Company
     will give prompt written notice to the Trustee of any such
     designation or rescission and of any change in the location of any
     such other office or agency.

               The Company hereby initially designates the Trustee as
     paying agent, Note registrar and conversion and exchange agent and
     each of the Corporate Trust Office of the Trustee and the office
     of State Street Bank and Trust Company, N.A. in the Borough of
     Manhattan, The City of New York, as one such office or agency of
     the Company for the purposes set forth in the first paragraph of
     this Section 5.2.

               So long as the Trustee is the Note registrar, the
     Trustee agrees to mail, or cause to be mailed, the notices set
     forth in Section 8.10(a) and the third paragraph of Section 8.11.

               Section 5.3  Appointments to Fill Vacancies in Trustee's
     office.  The Company, whenever necessary to avoid or fill a
     vacancy in the office of Trustee, will appoint, in the manner
     provided in Section 8.10, a Trustee, so that there shall at all
     times be a Trustee hereunder.

               Section 5.4  Provisions as to Paying Agent.

               (a)  If the Company shall appoint a paying agent other
     than the Trustee, or if the Trustee shall appoint such a paying
     agent, it will cause such paying agent to execute and deliver to
     the Trustee an instrument in which such agent shall agree with the
     Trustee, subject to the provisions of this Section 5.4:

                    (1)  that it will hold all sums held by it as such
               agent for the payment of the principal of, premium, if
               any, or interest on the Notes (whether such sums have
               been paid to it by the Company or by any other obligor
               on the Notes) in trust for the benefit of the holders of
               the Notes;

                    (2)  that it will give the Trustee notice of any
               failure by the Company (or by any other obligor on the
               Notes) to make any payment of the principal of, premium,
               if any, or interest on the Notes when the same shall be
               due and payable; and

                    (3)  that at any time during the continuance of an
               Event of Default, upon request of the Trustee, it will
               forthwith pay to the Trustee all sums so held in trust.

               The Company shall, before each due date of the principal
     of, premium, if any, or interest on the Notes, deposit with the
     paying agent a sum sufficient to pay such principal, premium, if
     any, or interest, and (unless such paying agent is the Trustee)
     the Company will promptly notify the Trustee of any failure to
     take such action.

               (b)  If the Company shall act as its own paying agent,
     it will, on or before each due date of the principal of, premium,
     if any, or interest on the Notes, set aside, segregate and hold in
     trust for the benefit of the holders of the Notes a sum sufficient
     to pay such principal, premium, if any, or interest so becoming
     due and will notify the Trustee of any failure to take such action
     and of any failure by the Company (or any other obligor under the
     Notes) to make any payment of the principal of, premium, if any,
     or interest on the Notes when the same shall become due and
     payable.

               (c)  Anything in this Section 5.4 to the contrary
     notwithstanding, the Company may, at any time, for the purpose of
     obtaining a satisfaction and discharge of this Indenture, or for

     required by this Section 5.4, such sums to be held by the Trustee
     upon the trusts herein contained and upon such payment by the
     company or any paying agent to the Trustee, the Company or such
     paying agent shall be released from all further liability with
     respect to such sums.

               (d)  Anything in this section 5.4 to the contrary
     notwithstanding, the agreement to hold sums in trust as provided
     in this Section 5.4 is subject to Sections 13.3 and 13.4.

               Section 5.6  Rule 144A Information Requirement.  During
     the three-year period following the original issuance date of any
     Note and during the three-year period following the last date on
     which the Company or an Affiliate of the Company was the owner of
     any Note (or shares of Common Stock issued upon conversion of any
     Note or Preferred Stock issued upon exchange of Notes), if the
     Company is subject neither to Section 13 nor Section 15(d) of the
     Exchange Act, the Company shall at the written request of any
     holder or beneficial holder of such Note (or shares of Preferred
     Stock issued upon exchange of Notes or Common Stock issued upon
     conversion of Notes) provide to such holder or beneficial holder
     of such Note (or shares of Common Stock issued upon conversion of
     Notes or Preferred Stock issued upon exchange of Notes) and any
     prospective transferee designated by such holder or beneficial
     holder of such Note (or shares of Preferred Stock issued upon
     exchange of Notes or Common Stock issued upon conversion of Notes)
     such information, if any, required by Rule 144A(d)(4) under the
     Securities Act (so long as such information is required to permit
     such transfer under Rule 144A).

               Section 5.7  Stay, Extension and Usury Laws.  The
     Company covenants (to the extent that it may lawfully do so) that
     it shall not at any time insist upon, plead or in any manner
     whatsoever claim or take the benefit or advantage of, any stay,
     extension or usury law or other law which would prohibit or
     forgive the Company from paying all or any portion of the
     principal of or interest on the Notes as contemplated herein,
     wherever enacted, now or at any time hereafter in force, or which
     may affect the covenants or the performance of this Indenture; and
     the Company (to the extent it may lawfully do so) hereby expressly
     waives all benefit or advantage of any such law, and covenants
     that it will not, by resort to any such law, hinder, delay or
     impede the execution of any power herein granted to the Trustee,
     but will suffer and permit the execution of every such power as
     though no such law has been enacted.

               Section 5.8  Amendments to Series C Preferred Stock. 
     Without the consent (evidenced as provided in Article IX) of the
     holders of not less than a majority in aggregate principal amount
     of the Notes at the time outstanding, the Company will not take
     any action with respect to its capital stock or adopt any change
     to the Certificate of Designation of the Series C Preferred Stock
     which in either such case would require the affirmative vote of
     the holders of at least 66-2/3% of the outstanding shares of
     Series C Preferred Stock under Section 3.2 of the Certificate of
     Designation (whether or not any such Series C Preferred Stock is
     at the time outstanding).

               Section 5.9    Statement as to Compliance  If this
     Indenture is qualified under the Trust Indenture Act, then the
     Company will deliver to the Trustee, within 120 days after the end
     of each fiscal year, a brief certificate from its principal
     executive officer, principal financial officer or principal
     accounting officer as to his or her knowledge of the Company's
     compliance with all conditions and covenants under this Indenture
     and in the event of any noncompliance, specifying such
     noncompliance and the nature and status thereof.  For purposes of
     this Section 5.9, such compliance shall be determined without
     regard to any period of grace or requirement of notice under this
     Indenture.

                              ARTICLE VI

             NOTEHOLDERS' LISTS AND REPORTS BY THE COMPANY

               Section 6.1  Noteholders' Lists.  The Company covenants
     and agrees that it will furnish or cause to be furnished to the
     Trustee, semi-annually, not more than 15 days after April 15 and
     October 15 in each year beginning with April 15, 1996, and at such
     other times as the Trustee may request in writing, within 30 days
     after receipt by the Company of any such request (or such lesser
     time as the Trustee may reasonably request in order to enable it
     to timely provide any notice to be provided by it hereunder), a
     list in such form as the Trustee may reasonably require of the
     names and addresses of the holders of Notes as of a date not more
     than 15 days (or such other date as the Trustee may reasonably
     request in order to so provide any such notices) prior to the time
     such information is furnished, except that no such list need be
     furnished so long as the Trustee is acting as Note registrar or
     co-registrar.

               Section 6.2  Reports by Company.  The Company will
     deliver to the Trustee (a) as soon as available and in any event
     within 90 days after the end of each fiscal year of the Company
     (i) a consolidated balance sheet of the Company and its
     subsidiaries as of the end of such fiscal year and the related
     consolidated statements of operations, stockholders, equity and
     cash flows for such fiscal year, all reported on by an independent
     public accountant of nationally recognized standing and (ii) a
     report containing a management's discussion and analysis of the
     financial condition and results of operations and a description of
     the business and properties of the Company and (b) as soon as
     available and in any event within 45 days after the end of each of
     the first three quarters of each fiscal year of the Company (i) an
     unaudited consolidated financial report for such quarter and (ii)
     a report containing a management's discussion and analysis of the
     financial condition and results of operations of the Company;
     provided that the foregoing shall not be required for any fiscal
     year or quarter, as the case may be, with respect to which the
     Company files or expects to file with the Trustee an annual report
     or quarterly report, as the case may be, pursuant to the next
     paragraph of this Section 6.2.

               The Company shall file with the Trustee, within 15 days
     after it files such annual and quarterly reports with the
     Commission such annual and quarterly reports as are required to be
     filed by the Company with the Commission pursuant to Section 13 or
     15(d) of the Exchange Act.  Except during the continuance of an
     Event of Default, the Trustee shall have no duty or obligation to
     examine any reports or other financial statements filed with it
     under this Indenture and shall not be required to monitor the
     financial condition of the Company.

                                   ARTICLE VII

                               DEFAULTS AND REMEDIES

               Section 7.1  Events of Default.  In case one or more of
     the following Events of Default (whatever the reason for such
     Event of Default and whether it shall be voluntary or involuntary
     or be effected by operation of law or pursuant to any judgment,
     decree or order of any court or any order, rule or regulation of
     any administrative or governmental body) shall have occurred and
     be continuing:

               (a)  default in the payment of any installment of
     interest upon any of the Notes as and when the same shall become
     due and payable, and continuance of such default for a period of
     30 days; or

               (b)  default in the payment of the principal of and
     premium, if any, on any of the Notes as and when the same shall
     become due and payable either at maturity or in connection with
     any redemption, by declaration or otherwise; or

               (c)  a failure on the part of the Company duly to
     observe or perform any other covenants or agreements on the part
     of the Company in the Notes or in this Indenture (other than a
     default in the performance or breach of a covenant or agreement
     which is specifically dealt with) elsewhere in this Section 7.1,
     which continues for a period of 90 days after the date on which
     written notice of such failure, requiring the Company to remedy
     the same, shall have been given to the Company by the Trustee, or
     to the Company and a Responsible Officer of the Trustee, by the
     holders of at least 25 percent in aggregate principal amount of
     the Notes at the time outstanding determined in accordance with
     Section 9.4; or

               (d)  the Company shall commence a voluntary case or
     other proceeding seeking liquidation, reorganization or other
     relief with respect to itself or its debts under any bankruptcy,
     insolvency or other similar law now or hereafter in effect, or
     seeking the appointment of a trustee, receiver, liquidator,
     custodian or other similar official of it or any substantial part
     of its property, or shall consent to any such relief or to the
     appointment of or taking possession by any such official in an
     involuntary case or other proceeding commenced against it or shall
     make a general assignment for the benefit of creditors or shall
     fail generally to pay its debts as they become due; or

               (e)  an involuntary case or other proceeding shall be
     commenced against the Company seeking liquidation, reorganization
     or other relief with respect to it or its debts under any
     bankruptcy, insolvency or other similar law now or hereafter in
     effect or seeking the appointment of a trustee, receiver,
     liquidator, custodian or other similar official of it or any
     substantial part of its property, and such involuntary case or
     other proceeding shall remain undismissed and unstayed for a
     period of 90 consecutive days; 

     then, and in each and every such case (other than an Event of
     Default specified in Section 7.1(d) or (e)), unless the principal
     of all of the Notes shall have already become due and payable,
     either the Trustee or the holders of not less than 25% in
     aggregate principal amount of the Notes then outstanding hereunder
     determined in accordance with Section 9.4, by notice in writing to
     the Company (and to the Trustee if given by Noteholders), may
     declare the principal of, premium, if any, on all the Notes and
     the interest accrued thereon to be due and payable immediately,
     and upon any such declaration the same shall become and shall be
     immediately due and payable, anything in this Indenture or in the
     Notes contained to the contrary notwithstanding.  If an Event of
     Default specified in Section 7.1(d) or (e) occurs and is
     continuing, the principal of all the Notes and the interest
     accrued thereon shall be immediately due and payable.  This
     provision, however, is subject to the conditions that if, at any
     time after the principal of the Notes shall have been so declared
     due and payable, and before any judgment or decree for the payment
     of the monies due shall have been obtained or entered as
     hereinafter provided, the Company shall pay or shall deposit with
     the Trustee a sum sufficient to pay all matured installments of
     interest upon all Notes and the principal of and premium, if any,
     on any and all Notes which shall have become due otherwise than by
     acceleration (with interest on overdue installments of interest
     (to the extent that payment of such interest is enforceable under
     applicable law) and on such principal and premium, if any, at the
     rate borne by the Notes, to the date of such payment or deposit)
     and amounts due to the Trustee pursuant to Section 8.6, and if any
     and all defaults under this Indenture, other than the nonpayment
     of principal of, premium, if any, and accrued interest on Notes
     which shall have become due by acceleration, shall have been cured
     or waived pursuant to Section 7.7, then and in every such case the
     holders of a majority in aggregate principal amount of the Notes
     then outstanding, by written notice to the Company and to the
     Trustee, may waive all defaults or Events of Default and rescind
     and annul such declaration and its consequences; but no such
     waiver or rescission and annulment shall extend to or shall affect
     any subsequent default or Event of Default, or shall impair any
     right consequent thereto.  The Company shall notify a Responsible
     Officer of the Trustee, promptly upon becoming aware thereof, of
     any Event of Default.

               In case the Trustee shall have proceeded to enforce any
     right under this Indenture and such proceedings shall have been
     discontinued or abandoned because of such waiver or rescission and
     annulment or for any other reason or shall have been determined
     adversely to the Trustee, then and in every such case the Company,
     the holders of Notes and the Trustee shall be restored
     respectively to their several positions and rights hereunder, and
     all rights, remedies and powers of the Company, the holders of
     Notes and the Trustee shall continue as though no such proceeding
     had been taken.

               Section 7.2  Payments of Notes on Default; Suit
     Therefor.  The Company covenants that (a) in case default shall be
     made in the payment of any installment of interest upon any of the
     Notes as and when the same shall become due and payable, and such
     default shall have continued for a period of 30 days, or (b) in
     case default shall be made in the payment of the principal of or
     premium, if any, on any of the Notes as and when the same shall
     have become due and payable, whether at maturity of the Notes or
     in connection with any redemption, by declaration or otherwise,
     then, upon demand of the Trustee, the Company will pay to the
     Trustee, for the benefit of the holders of the Notes, the whole
     amount that then shall have become due and payable on all such
     Notes for principal, premium, if any, or interest, or both, as the
     case may be, with interest upon the overdue principal, premium, if
     any, and (to the extent that payment of such interest is
     enforceable under applicable law) upon the overdue installments of
     interest at the rate borne by the Notes; and, in addition thereto,
     such further amount as shall be sufficient to cover the costs and
     expenses of collection, including reasonable compensation to the
     Trustee, its agents, attorneys and counsel, and any expenses or
     liabilities incurred by the Trustee hereunder other than through
     its negligence or bad faith.  Until such demand by the Trustee,
     the Company may pay the principal of and premium, if any, and
     interest on the Notes to the registered holders, whether or not
     the Notes are overdue; provided, however, that the Company shall
     provide notice (in the form of an Officer's Certificate) to the
     Trustee of any such payment.

               In case the Company shall fail forthwith to pay such
     amounts upon such demand, the Trustee, in its own name and as
     trustee of an express trust, shall be entitled and empowered to
     institute any actions or proceedings at law or in equity for the
     collection of the sums so due and unpaid and may prosecute any
     such action or proceeding to judgment or final decree, and may
     enforce any such judgment or final decree against the Company or
     any other obligor on the Notes and collect in the manner provided
     by law out of the property of the Company or any other obligor on
     the Notes wherever situated the monies adjudged or decreed to be
     payable.

               In the case there shall be pending proceedings for the
     bankruptcy or for the reorganization of the Company or any other
     obligor on the Notes under Title 11 of the United States Code or
     any other applicable law, or in case a receiver, assignee or
     trustee in bankruptcy or reorganization, liquidator, sequestrator
     or similar official shall have been appointed for or taken
     possession of the Company or such other obligor, the property of
     the Company or such other obligor, or in the case of any other
     judicial proceedings relative to the Company or such other obligor
     upon the Notes, or to the creditors or property of the Company or
     such other obligor, the Trustee, irrespective of whether the
     principal of the Notes shall then be due and payable as therein
     expressed or by declaration or otherwise and irrespective of
     whether the Trustee shall have made any demand pursuant to the
     provisions of this Section 7.2, shall be entitled and empowered,
     by intervention in such proceedings or otherwise, to file and
     prove a claim or claims for the whole amount of principal,
     premium, if any, and interest owing and unpaid in respect of the
     Notes and, in case of any judicial proceedings, to file such
     proofs of claim and other papers or documents and to take such
     other actions (including participating in a committee of
     creditors) as may be necessary or advisable in order to have the
     claims of the Trustee and of the Noteholders allowed in such
     judicial proceedings relative to the Company or any other obligor
     on the Notes, its or their creditors, or its or their property and
     to collect and receive any monies or other property payable or
     deliverable on any such claims and to distribute the same after
     the deduction of any amounts due the Trustee under Section 8.6;
     and any receiver, assignee or trustee in bankruptcy or
     reorganization, liquidator, custodian or similar official is
     hereby authorized by each of the Noteholders to make such payments
     to the Trustee and, in the event that the Trustee shall consent to
     the making of such payments directly to the Noteholders, to pay to
     the Trustee any amount due it for reasonable compensation,
     expenses, advances and disbursements, including counsel fees
     incurred by it up to the date of such distribution.  To the extent
     that such payment of reasonable compensation, expenses, advances
     and disbursements out of the estate in any such proceedings shall
     be denied for any reason, payment of the same shall be secured by
     a lien on, and shall be paid out of, any and all distributions,
     dividends, monies, securities and other property which the holders
     of the Notes may be entitled to receive in such proceedings,
     whether in liquidation or under any plan of reorganization or
     arrangement or otherwise.

               Nothing herein contained shall be deemed to authorize
     the Trustee to authorize or consent to or adopt on behalf of any
     Noteholder any plan of reorganization or arrangement affecting the
     Notes or the rights of any Noteholder, or to authorize the Trustee
     to vote in respect of the claim of any Noteholder in any such
     proceeding.

               All rights of action and of asserting claims under this
     Indenture, or under any of the Notes, may be enforced by the
     Trustee without the possession of any of the Notes or the
     production thereof on any trial or other proceeding relative
     thereto, and any such suit or proceeding instituted by the Trustee
     shall be brought in its own name as trustee of an express trust,
     and any recovery of judgment shall, after provision for the
     payment of the reasonable compensation, expenses, disbursements
     and advances of the Trustee, its agents and counsel, be for the
     ratable benefit of the holders of the Notes.

               In any proceedings brought by the Trustee (and in any
     proceedings involving the interpretation of any provision of this
     Indenture to which the Trustee shall be a party), the Trustee
     shall be held to represent all the holders of the Notes, and it
     shall not be necessary to make any holders of the Notes parties to
     any such proceedings.

               Section 7.3  Application of Monies Collected by Trustee. 
     Any monies collected by the Trustee pursuant to this Article VII
     shall be applied in the order following, at the date or dates
     fixed by the Trustee for the distribution of such monies, upon
     presentation of the several Notes and stamping thereon the
     payment, if only partially paid, and upon surrender thereof, if
     fully paid:

               First:    To the payment of all amounts due the Trustee
          under Section 8.6;

               Second:   Subject to the provisions of Article V, in
          case the principal of the outstanding Notes shall not have
          become due and be unpaid, to the payment of interest on the
          Notes in default in the order of the maturity of the
          installments of such interest, with interest (to the extent
          that such interest has been collected by the Trustee) upon
          the overdue installments of interest at the rate borne by the
          Notes, such payments to be made ratably to the persons
          entitled thereto; and

               Third:    Subject to the Provisions of Article V, in
          case the principal of the outstanding Notes shall have become
          due, by declaration or otherwise, and be unpaid, to the
          payment of the whole amount then owing and unpaid upon the
          Notes for principal, premium, if any, and interest, with
          interest on the overdue principal and premium, if any, and
          (to the extent that such interest has been collected by the
          Trustee) upon overdue installments of interest at the rate
          borne by the Notes; and in case such monies shall be
          insufficient to pay in full the whole amounts so due and
          unpaid upon the Notes, then to the payment of such principal,
          premium, if any, and interest without preference or priority
          of principal and premium, if any, over interest, or of
          interest over principal and premium, if any, or of any
          installment of interest over any other installment of
          interest, or of any Note over any other Note, ratably to the
          aggregate of such principal and premium, if any, and accrued
          and unpaid interest.

               Section 7.4  Proceedings by Noteholder.  No holder of
     any Note shall have any right by virtue of or by availing of any
     provision of this Indenture to institute any suit, action or
     proceeding in equity or at law upon or under or with respect to
     this Indenture, or for the appointment of a receiver, trustee,
     liquidator, custodian or other similar official, or for any other
     remedy hereunder, unless such holder previously shall have given
     to the Trustee written notice of an Event of Default and of the
     continuance thereof, as hereinbefore provided, and unless also the
     holders of not less than 25 percent in aggregate principal amount
     of the Notes then outstanding shall have made written request upon
     the Trustee to institute such action, suit or proceeding in its
     own name as Trustee hereunder and shall have offered to the
     Trustee such reasonable indemnity as it may require against the
     costs, expenses and liabilities to be incurred therein or thereby,
     and the Trustee for 60 days after its receipt of such notice,
     request and offer of indemnity, shall have neglected or refused to
     institute any such action, suit or proceeding, and no direction
     inconsistent with such written request shall have been given to
     the Trustee pursuant to Section 7.7; it being understood and
     intended, and being expressly covenanted by the taker and holder
     of every Note with every other taker and holder and the Trustee,
     that no one or more holders of Notes shall have any right in any
     manner whatever by virtue of or by availing of any provision of
     this Indenture to affect, disturb or prejudice the rights of any
     other holder of Notes, to obtain or seek to obtain priority over
     or preference to any other such holder or to enforce any right
     under this Indenture, except in the manner herein provided and for
     the equal, ratable and common benefit of all holders of Notes
     (except as otherwise provided herein).  For the protection and
     enforcement of this Section 7.4, each and every Noteholder and the
     Trustee shall be entitled to such relief as can be given either at
     law or in equity.

               Notwithstanding any other provision of this Indenture
     and any provision of any Note, the right of any holder of any Note
     to receive payment of the principal of, premium, if any, and
     interest on such Note, on or after the respective due dates
     expressed in such Note, or to institute suit for the enforcement
     of any such payment on or after such respective dates against the
     Company shall not be impaired or affected without the consent of
     such holder.

               Anything in this Indenture or the Notes to the contrary
     notwithstanding, the holder of any Note, without the consent of
     either the Trustee or the holder of any other Note, in his own
     behalf and for his own benefit, may enforce, and may institute and
     maintain any proceeding suitable to enforce, his rights of
     conversion as provided herein.

               Section 7.5  Proceedings by Trustee.  In case of an
     Event of Default, the Trustee may in its discretion proceed to
     protect and enforce the rights vested in it by this Indenture by
     such appropriate judicial proceedings as the Trustee shall deem
     most effectual to protect and enforce any of such rights, either
     by suit in equity or by action at law or by proceeding in
     bankruptcy or otherwise, whether for the specific enforcement of
     any covenant or agreement contained in this Indenture or in aid of
     the exercise of any power granted in this Indenture or to enforce
     any other legal or equitable right vested in the Trustee by this
     Indenture or by law.

               Section 7.6  Remedies Cumulative and Continuing.  Except
     as provided in Section 2.6, all powers and remedies given by this
     Article VII to the Trustee or to the Noteholders shall, to the
     extent permitted by law, be deemed cumulative and not exclusive of
     such powers and remedies or of any other powers and remedies
     available to the Trustee or the holders of the Notes, by judicial
     proceedings or otherwise, to enforce the performance or observance
     of the covenants and agreements contained in this Indenture, and
     no delay or omission of the Trustee or of any holder of any of the
     Notes to exercise any right or power accruing upon any default or
     Event of Default occurring and continuing as aforesaid shall
     impair any such right or power or shall be construed to be a
     waiver of any such default or any acquiescence therein; and,
     subject to the provisions of Section 7.4, every power and remedy
     given by this Article VII or by law to the Trustee or to the
     Noteholders may be exercised from time to time, and as often as
     shall be deemed expedient, by the Trustee or by the Noteholders.

               Section 7.7  Direction of Proceedings and Waiver of
     Defaults by Majority of Noteholders.  The holders of a majority in
     aggregate principal amount of the Notes at the time outstanding
     (determined in accordance with Section 9.4) shall have the right
     to direct the time, method and place of conducting any proceeding
     for any remedy available to the Trustee or exercising any trust or
     power conferred on the Trustee; provided, however, that (a) such
     direction shall not be in conflict with any rule of law or with
     this Indenture, (b) the Trustee may take any other action deemed
     proper by the Trustee which is not inconsistent with such
     direction and (c) such holder or holders agree to indemnify the
     Trustee, in a manner reasonably satisfactory to the Trustee,
     against any loss, liability or expense incurred in connection
     therewith.  The holders of a majority in aggregate principal
     amount of the Notes at the time outstanding (determined in
     accordance with Section 9.4) may on behalf of the holders of all
     of the Notes waive any past default or Event of Default hereunder
     and its consequences except (i) a default in the payment of
     interest or premium, if any, on, or the principal of, the Notes,
     (ii) a failure by the Company to exchange any Notes for Preferred
     Stock or to convert any Notes into Common Stock or (iii) a default
     in respect of a covenant or provisions hereof which under Article
     XI cannot be modified or amended without the consent of the
     holders of all Notes then outstanding.  Upon any such waiver, the
     Company, the Trustee and the holders of the Notes shall be
     restored to their former positions and rights hereunder; but no
     such waiver shall extend to any subsequent or other default or
     Event of Default or impair any right consequent thereon.  Whenever
     any default or Event of Default hereunder shall have been waived
     as permitted by this Section 7.7, said default or Event of Default
     shall for all purposes of the Notes and this Indenture be deemed
     to have been cured and to be not continuing; but no such waiver
     shall extend to any subsequent or other default or Event of
     Default or impair any right consequent thereon.

               Section 7.8  Notice of Defaults.  The Trustee shall,
     within 90 days after the occurrence of an Event of Default, mail
     to all Noteholders, as the names and addresses of such holders
     appear upon the registry books of the Company, notice of all
     Events of Default known to a Responsible Officer, unless such
     Events of Default shall have been cured or waived before the
     giving of such notice; and provided that, except in the case of
     Events of Default in the payment of the principal of, premium, if
     any, or interest on any of the Notes, the Trustee shall be
     protected in withholding such notice if and so long as a trust
     committee of directors and/or Responsible Officers of the Trustee
     in good faith determine that the withholding of such notice is in
     the interests of the Noteholders.

               Section 7.9  Undertaking to Pay Costs.  All parties to
     this Indenture agree, and each holder of any Note by his
     acceptance thereof shall be deemed to have agreed, that any court
     may, in its discretion, require, in any suit for the enforcement
     of any right or remedy under this Indenture, or in any suit
     against the Trustee for any action taken or omitted by it as
     Trustee, the filing by any party litigant in such suit of an
     undertaking to pay the costs of such suit and that such court may
     in its discretion assess reasonable costs, including reasonable
     attorneys' fees, against any party litigant in such suit, having
     due regard to the merits and good faith of the claims or defenses
     made by such party litigant; provided that the provisions of this
     Section 7.9 shall not apply to any suit instituted by the Trustee,
     to any suit instituted by any Noteholder or group of Noteholders
     holding in the aggregate more than ten percent in principal amount
     of the Notes at the time outstanding determined in accordance with
     Section 9.4 or to any suit instituted by any Noteholder for the
     enforcement of the payment of the principal of, premium, if any,
     or interest on any Note on or after the due date expressed in such
     Note or to any suit for the enforcement of the right to convert
     any Note in accordance with the provisions of Article XV or of the
     right to exchange any Note in accordance with the provisions of
     Article XVII.

                                 ARTICLE VIII

                             CONCERNING THE TRUSTEE

               Section 8.1  Duties and Responsibilities of Trustee. (a)
     if an Event of Default has occurred and is continuing, the Trustee
     shall exercise the rights and powers vested in it by this
     Indenture and use the same degree of care and skill in its
     exercise as a prudent person would exercise or use under the
     circumstances in the conduct of such person's own affairs.

               (b)  Except during the continuance of an Event of
     Default:

                    (1)  the Trustee need perform only those duties
               that are specifically set forth in this Indenture and no
               others; and

                    (2)  in the absence of bad faith on its part, the
               Trustee may conclusively rely, as to the truth of the
               statements and the correctness of the opinions expressed
               therein, upon certificates or opinions furnished to the
               Trustee and conforming to the requirements of this
               Indenture; provided that the Trustee shall examine such
               certificates and opinions to determine whether or not
               they conform to the requirements of this Indenture.

               (c)  The Trustee may not be relieved from liability for
     its own negligent action, its own negligent failure to act or its
     own willful misconduct, except that:

                    (1)  this paragraph (c) does not limit the effect
               of paragraph (b) of this section 8.1;

                    (2)  the Trustee shall not be liable for any error
               of judgment made in good faith by an officer of the
               Trustee unless it is proved that the Trustee was
               negligent in ascertaining the pertinent facts; and

                    (3)  the Trustee shall not be liable with respect
               to any action it takes or omits to take in good faith in
               accordance with a direction received by it pursuant to
               Section 7.7.

               (d)  Every provision of this Indenture that in any way
     relates to the Trustee is subject to paragraphs (a), (b), (c) and
     (e) of this Section 8.1.

               (e)  The Trustee may refuse to perform any duty or
     exercise any right or power or extend or risk its own funds or
     otherwise incur any financial liability unless it receives
     indemnity satisfactory to it against any loss, liability or
     expense.

               Section 8.2  Reliance on Documents, Opinions, Etc. 
     Except as otherwise provided in Section 8.1:

               (a)  The Trustee may rely and shall be protected in
     acting upon any resolution, certificate, statement, instrument,
     opinion, report, notice, request, consent, order, bond, debenture,
     coupon or other paper or document believed by it in good faith to
     be genuine and to have been signed or presented by the proper
     party or parties;

               (b)  Any request, direction, order or demand of the
     Company mentioned herein shall be sufficiently evidenced by an
     Officers' Certificate (unless other evidence in respect thereof be
     herein specifically prescribed); and any resolution of the Board
     of Directors may be evidenced to the Trustee by a copy thereof
     certified by the Secretary or an Assistant Secretary of the
     Company;

               (c)  The Trustee may consult with counsel and any advice
     or Opinion of Counsel shall be full and complete authorization and
     protection in respect of any action taken or omitted by it
     hereunder in good faith and in accordance with such advice or
     Opinion of Counsel;

               (d)  The Trustee may execute any of the trusts or powers
     hereunder or perform any duties hereunder either directly or by or
     through agents or attorneys, and the Trustee shall not be
     responsible for any misconduct or negligence on the part of any
     agent or attorney appointed by it with due care hereunder; no
     Depositary, Custodian or paying agent who is not the Trustee shall
     be deemed an agent of the Trustee, and the Trustee (in its
     capacity as Trustee) shall not be responsible for any act or
     omission by any such Depositary, Custodian or paying agent;

               (e)  The Trustee shall be under no obligation to
     exercise any of the rights or powers vested in it by the Indenture
     at the request or direction of any of the holders pursuant to this
     Indenture unless such holders have offered the Trustee reasonable
     security or indemnity against the costs, expenses and liabilities
     which would be incurred by it in compliance with such request or
     direction.

               (f)  Subject to the provisions of Section 8.1(c), the
     Trustee shall not be liable for any action it takes or omits to
     take in good faith which it believes to be authorized or within
     its rights or powers;

               (g)  In connection with any request to transfer or
     exchange any Note, the Trustee may request a direction (in the
     form of an Officers'  Certificate) from the Company and an Opinion
     of Counsel with respect to compliance with any restrictions on
     transfer or exchange imposed by this Indenture, the Securities
     Act, other applicable law or the rules and regulations of any
     exchange on which the Notes or the capital stock may be traded,
     and the Trustee may rely and shall be protected in acting upon
     such direction and in accordance with such Officers' Certificate
     and Opinion of Counsel;

               (h)  The Trustee may rely and shall be fully protected
     in acting upon the determination and notice by the Company of the
     Conversion Price, including any adjustment to the Conversion Price
     pursuant to Section 15.5(j) or the Exchange Price pursuant to
     Section 17.5; and

               (i)  The Trustee shall not be deemed to have knowledge
     of any Event of Default or other fact or event upon the occurrence
     of which it may be required to take action hereunder unless one of
     its Responsible Officers has actual knowledge thereof.

               Section 8.3  No Responsibility for Recitals, Etc.  The
     recitals contained herein and in the Notes (except in the
     Trustee's certificate of authentication) shall be taken as the
     statements of the Company, and the Trustee assumes no
     responsibility for the correctness of the same.  The Trustee makes
     no representations as to the validity or sufficiency of this
     Indenture or of the Notes.  The Trustee shall not be accountable
     for the use or application by the Company of any Notes or the
     proceeds of any Notes authenticated and delivered by the Trustee
     in conformity with the provisions of this Indenture.

               Section 8.4  Trustee, Paying Agents, Exchange Agents,
     Conversion Agents or Registrar May own Notes.  The Trustee, any
     paying agent, any exchange agent, any conversion agent or any Note
     registrar, in its individual or any other capacity, may become the
     owner or pledgee of Notes with the same rights it would have if it
     were not Trustee, paying agent, exchange agent, conversion agent
     or Note registrar.

               Section 8.5  Monies to Be Held in Trust.  Subject to the
     provisions of Section 13.4, all monies received by the Trustee
     shall, until used or applied as herein provided, be held in trust
     for the purposes for which they were received.  Money held by the
     Trustee in trust hereunder need not be segregated from other funds
     except to the extent required by law.  The Trustee shall be under
     no liability for interest on any money received by it hereunder
     except as may be agreed in writing from time to time by the
     Company and the Trustee.

               Section 8.6  Compensation and Expenses of Trustee.  The
     Company covenants and agrees to pay to the Trustee from time to
     time, and the Trustee shall be entitled to, reasonable
     compensation for all services rendered by it hereunder in any
     capacity (which shall not be limited by any provision of law in
     regard to the compensation of a trustee of an express trust), and
     the Company will pay or reimburse the Trustee upon its request for
     all reasonable expenses, disbursements and advances incurred or
     made by the Trustee in accordance with any of the provisions of
     this Indenture (including the reasonable compensation and the
     expenses and disbursements of its counsel and of all persons not
     regularly in its employ) except any such expense, disbursement or
     advance as may arise from its negligence or bad faith.  The
     Company also covenants to indemnify the Trustee in any capacity
     under this Indenture and its agents and any authenticating agent
     for, and to hold them harmless against, any loss, liability or
     expense incurred without negligence or bad faith on the part of
     the Trustee or such agent or authenticating agent, as the case may
     be, and arising out of or in connection with the acceptance or
     administration of this trust or in any other capacity hereunder,
     including the costs and expenses of defending themselves against
     any claim of liability in the premises.  The obligations of the
     Company under this Section 8.6 to compensate or indemnify the
     Trustee and to pay or reimburse the Trustee for expenses,
     disbursements and advances shall be secured by a lien prior to
     that of the Notes upon all property and funds held or collected by
     the Trustee as such, except funds held in trust for the benefit of
     the holders of particular Notes.  The obligation of the Company
     under this Section shall survive the satisfaction and discharge of
     this Indenture.

               Section 8.7  Officers' Certificate as Evidence.  Except
     as otherwise provided in Section 8.1, whenever in the
     administration of the provisions of this Indenture the Trustee
     shall deem it necessary or desirable that a matter be proved or
     established prior to taking or omitting any action hereunder, such
     matter (unless other evidence in respect thereof be herein
     specifically prescribed) may, in the absence of negligence or bad
     faith on the part of the Trustee, be deemed to be conclusively
     proved and established by an Officers' Certificate delivered to
     the Trustee, and such Officers' Certificate, in the absence of
     negligence or bad faith on the part of the Trustee, shall be full
     warrant to the Trustee for any action taken or omitted by it under
     the provisions of this Indenture upon the faith thereof.

               Section 8.8  Conflicting Interests of Trustee.  In the
     event that the Trust Indenture Act is applicable hereto, the
     Trustee has or shall acquire a conflicting interest within the
     meaning of the Trust Indenture Act and there exists an Event of
     Default hereunder (exclusive of any period of grace or requirement
     of notice), the Trustee shall either eliminate such interest or
     resign, to the extent and in the manner provided by, and subject
     to the provisions of, the Trust Indenture Act and this Indenture.

               Section 8.9  Eligibility of Trustee.  There shall at all
     times be a Trustee hereunder which shall be a person that is
     eligible pursuant to the Trust Indenture Act to act as such and
     has a combined capital and surplus of at least $50,000,000.  If
     such person publishes reports of condition at least annually,
     pursuant to law or to the requirements of any supervising or
     examining authority, then for the purposes of this Section, the
     combined capital and surplus of such person shall be deemed to be
     its combined capital and surplus as set forth in its most recent
     report of condition so published.  If at any time the Trustee
     shall cease to be eligible in accordance with the provisions of
     this Section, it shall resign immediately in the manner and with
     the effect hereinafter specified in this Article VIII.

               Section 8.10  Resignation or Removal of Trustee. (a) The
     Trustee may at any time resign by giving written notice of such
     resignation to the Company; and the Company shall mail, or cause
     to be mailed, notice thereof to the holders of Notes at their
     addresses as they shall appear on the registry books of the
     Company.  Upon receiving such notice of resignation, the Company
     shall promptly appoint a successor trustee by written instrument,
     in duplicate, executed by order of the Board of Directors, one
     copy of which instrument shall be delivered to the resigning
     Trustee and one copy to the successor trustee.  If a successor
     trustee shall not have been so appointed and shall not have
     accepted appointment 60 days after the mailing of such notice of
     resignation to the Noteholders, the resigning Trustee may petition
     any court of competent jurisdiction for the appointment of a
     successor trustee, or any Noteholder who has been a bona fide
     holder of a Note or Notes for at least six months may, subject to
     the provisions of Section 7.9, on behalf of himself and all others
     similarly situated, petition any such court for the appointment of
     a successor trustee.  Such court may thereupon, after such notice,
     if any, as it may deem proper and prescribe, appoint a successor
     trustee.

               (b)  In case at any time any of the following shall
     occur:

                    (1)  the Trustee shall fail to comply with Section
          8.8 after written request therefor by the Company or by any
          Noteholder who has been a bona fide holder of a Note or Notes
          for at least six months; or

                    (2)  the Trustee shall cease to be eligible in
          accordance with the provisions of Section 8.9 and shall fail
          to resign after written request therefor by the Company or by
          any such Noteholder; or

                    (3)  the Trustee shall become incapable of acting,
          or shall be adjudged a bankrupt or insolvent, or a receiver
          of the Trustee or of its property shall be appointed, or any
          public officer shall take charge or control of the Trustee or
          of its property or affairs for the purpose of rehabilitation,
          conservation or liquidation, 

     then, in any such case, the Company may remove the Trustee and
     appoint a successor trustee by written instrument, in duplicate,
     executed by order of the Board of Directors, one copy of which
     instrument shall be delivered to the Trustee so removed and one
     copy to the successor trustee or, subject to the provisions of
     Section 7.9, any Noteholder who has been a bona fide holder of a
     Note or Notes for at least six months may, on behalf of himself
     and all others similarly situated, petition any court of competent
     jurisdiction for the removal of the Trustee and the appointment of
     a successor trustee.  Such court may thereupon, after such notice,
     if any, as it may deem proper and prescribe, remove the Trustee
     and appoint a successor trustee.

               (c)  The holders of a majority in aggregate principal
     amount of the Notes at the time outstanding may at any time remove
     the Trustee and nominate a successor trustee which shall be deemed
     appointed as successor trustee unless within ten days after notice
     to the Company of such nomination the Company objects thereto, in
     which case the Trustee so removed or any Noteholder, upon the
     terms and conditions and otherwise as in Section 8.10(a) provided,
     may petition any court of competent jurisdiction for an
     appointment of a successor trustee.

               (d)  Any resignation or removal of the Trustee and
     appointment of a successor trustee pursuant to any of the
     provisions of this Section 8.10 shall become effective upon
     acceptance of appointment by the successor trustee as provided in
     Section 8.11.

               Section 8.11  Acceptance by Successor Trustee.  Any
     successor trustee appointed as provided in Section 8.10 shall
     execute, acknowledge and deliver to the Company and to its
     predecessor trustee an instrument accepting such appointment
     hereunder, and thereupon, the resignation or removal of the
     predecessor trustee shall become effective and such successor
     trustee, without any further act, deed or conveyance, shall become
     vested with all the rights, powers, duties and obligations of its
     predecessor hereunder, with like effect as if originally named as
     trustee herein; but, nevertheless, on the written request of the
     Company or of the successor trustee, the Trustee ceasing to act
     shall, upon payment of any amounts then due it pursuant to the
     provisions of Section 8.6, execute and deliver an instrument
     transferring to such successor trustee all the rights and powers
     of the Trustee so ceasing to act.  Upon request of any such
     successor trustee, the Company shall execute any and all
     instruments in writing for more fully and certainly vesting in and
     confirming to such successor trustee all such rights and powers. 
     Any Trustee ceasing to act shall, nevertheless, retain a lien upon
     all property and funds held or collected by such trustee as such,
     except for funds held in trust for the benefit of holders of
     particular Notes, to secure any amounts then due it pursuant to
     the provisions of Section 8.6.

               No successor trustee shall accept appointment as
     provided in this Section 8.11 unless at the time of such
     acceptance such successor trustee shall be qualified under the
     provisions of Section 8.8 and eligible under the provisions of
     Section 8.9.

               Upon acceptance of appointment by a successor trustee as
     provided in this Section 8.11, the Company shall mail or cause to
     be mailed notice of the succession of such Trustee hereunder to
     the holders of Notes at their addresses as they shall appear on
     the registry books of the Company.  If the Company fails to mail
     such notice within ten days after acceptance of appointment by the
     successor trustee, the successor trustee shall cause such notice
     to be mailed at the expense of the Company.

               Section 8.12  Successor, by Merger, Etc.  Any
     corporation into which the Trustee may be merged or converted or
     with which it may be consolidated, or any corporation resulting
     from any merger, conversion or consolidation to which the Trustee
     shall be a party, or any corporation succeeding to all or
     substantially all of the corporate trust business of the Trustee,
     shall be the successor to the Trustee hereunder, provided such
     corporation shall be qualified under the provisions of Section 8.8
     and eligible under the provisions of Section 8.9 without the
     execution or filing of any paper or any further act on the part of
     any of the parties hereto.

               Section 8.13  Limitation on Rights of Trustee as
     Creditor.  If and when the Trustee shall be or become a creditor
     of the Company (or any other obligor upon the Notes) and the Trust
     Indenture Act is applicable hereto, the Trustee shall be subject
     to the provisions of the Trust Indenture Act regarding the
     collection of the claims against the Company (or any such other
     obligor).

                                 ARTICLE IX

                           CONCERNING THE NOTEHOLDERS

               Section 9.1  Action by Noteholders.  Whenever in this
     Indenture it is provided that the holders of a specified
     percentage in aggregate principal amount of the Notes may take any
     action (including the making of any demand or request, the giving
     of any notice, consent or waiver or the taking of any other
     action), the fact that at the time of taking any such action, the
     holders of such specified percentage have joined therein may be
     evidenced (a) by any instrument or any number of instruments of
     similar tenor executed by Noteholders in person or by agent or
     proxy appointed in writing (b) by the record of the holders of
     Notes voting in favor thereof at any meeting of Noteholders duly
     called and held in accordance with the provisions of Article X or
     (c) by a combination of such instrument or instruments and any
     such record of such a meeting of Noteholders.  Whenever the
     Company or the Trustee solicits the taking of any action by the
     holders of the Notes, the Company or the Trustee may fix in
     advance of such solicitation, a date as the record date for
     determining holders entitled to take such action.  The record date
     shall be not more than 15 days prior to the date of commencement
     of solicitation of such action.

               Section 9.2  Proof of Execution by Noteholders.  Subject
     to the provisions of Sections 8.1, 8.2 and 11.5, proof of the
     execution of any instrument by a Noteholder or his agent or proxy
     shall be sufficient if made in accordance with such reasonable
     rules and regulations as may be prescribed by the Trustee or in
     such manner as shall be satisfactory to the Trustee.  The holding
     of Notes shall be proved by the Note register or by a certificate
     of the Note registrar. 

               The record of any Noteholders' meeting shall be proved
     in the manner provided in Section 9.1.

               Section 9.3  Who Are Deemed Absolute Owners.  The
     Company, the Trustee, any paying agent, any conversion or exchange
     agent and any Note registrar may deem the person in whose name
     such Note shall be registered upon the books of the Company to be,
     and may treat him as, the absolute owner of such Note (whether or
     not such Note shall be overdue and notwithstanding any notation of
     ownership or other writing thereon) for the purpose of receiving
     payment of or on account of the principal of, premium, if any, and
     interest on such Note, for conversion or exchange of such Note and
     for all other purposes; and neither the Company nor the Trustee
     nor any paying agent nor any conversion or exchange agent nor any
     Note registrar shall be affected by any notice to the contrary. 
     All such payments so made to any holder for the time being, or
     upon his order, shall be valid and, to the extent of the sum or
     sums so paid, effectual to satisfy and discharge the liability for
     monies payable upon any such Note.

               The Depositary shall be deemed to be the owner of any
     Note in global form for all purposes, including receipt of notices
     to Noteholders and payment of principal of, premium, if any, and
     interest on the Notes.  None of the Company, the Trustee (in its
     capacity as Trustee), any paying agent or the Note registrar (or
     co-registrar) will have any responsibility for any aspect of the
     records relating to or payments made on account of beneficial
     interests of a Note in global form or for maintaining, supervising
     or reviewing any records relating to such beneficial ownership
     interests; provided, however, that the foregoing shall not apply
     to the Trustee or any other person acting in its capacity as
     Custodian.

               Section 9.4  Company-Owned Notes Disregarded.  In
     determining whether the holders of the requisite aggregate
     principal amount of Notes have concurred in any direction,
     consent, waiver or other action under this Indenture, Notes which
     are owned by the Company or any other obligor on the Notes or by
     any person directly or indirectly controlling or controlled by or
     under direct or indirect common control with the Company or any
     other obligor on the Notes shall be disregarded and deemed not to
     be outstanding for the purpose of any such determination; provided
     that for the purposes of determining whether the Trustee shall be
     protected in relying on any such direction, consent, waiver or
     other action, only Notes which a Responsible Officer knows are so
     owned shall be so disregarded.  Notes so owned which have been
     pledged in good faith may be regarded as outstanding for the
     purposes of this Section 9.4 if the pledgee shall establish to the
     satisfaction of the Trustee the pledger's right to vote such Notes
     and that the pledgee is not the Company, any other obligor on the
     Notes or a person directly or indirectly controlling or controlled
     by or under direct or indirect common control with the Company or
     any such other obligor.  In the case of a dispute as to such
     right, any decision by the Trustee taken upon the advice of
     counsel shall be full protection to the Trustee.  Upon request of
     the Trustee, the Company shall furnish to the Trustee promptly an
     Officers' Certificate listing and identifying all Notes, if any,
     known by the Company to be owned or held by or for the account of
     any of the above described persons; and subject to Section 8.1,
     the Trustee shall be entitled to accept such Officers' Certificate
     as conclusive evidence of the facts therein set forth and of the
     fact that all Notes not listed therein are outstanding for the
     purpose of any such determination.

               Section 9.5  Revocation of Consents, Future Holders
     Bound.  At any time prior to (but not after) the evidencing to the
     Trustee, as provided in Section 9.1, of the taking of any action
     by the holders of the percentage in aggregate principal amount of
     the Notes specified in this Indenture in connection with such
     action, any holder of a Note which is shown by the evidence to be
     included in the Notes the holders of which have consented to such
     action may, by filing written notice with the Trustee at its
     Corporate Trust Office and upon proof of holding as provided in
     Section 9.2, revoke such action so far as concerns such Note. 
     Except as aforesaid, any such action taken by the holder of any
     Note shall be conclusive and binding upon such holder and upon all
     future holders and owners of such Note and of any Notes issued in
     exchange or substitution therefor, irrespective of whether any
     notation in regard thereto is made upon such Note or any Note
     issued in exchange or substitution therefor.

     A meeting of Noteholders may be called at any time and from time
     to time pursuant to the provisions of this Article X for any of
     the following purposes:

               (i)  to give any notice to the Company or to the
     Trustee, or to give any directions to the Trustee, or to consent
     to the waiving of any default hereunder and its consequences, or
     to take any other action authorized to be taken by Noteholders
     pursuant to any of the provisions of Article VII;

               (ii)  to remove the Trustee and appoint a successor
     trustee pursuant to the provisions of Article VIII;

               (iii)  consent to the execution of an indenture or

               (iv)  to take any other action authorized to be taken by
     or on behalf of the holders of any specified aggregate principal
     amount of the Notes under any other provisions of this Indenture
     or under applicable law.

               Section 10.2  Manner of Calling Meetings; Record Date. 
     The Trustee may at any time call a meeting of Noteholders to take
     any action specified in Section 10.1, to be held at such time and
     at such place in the City of Boston, Commonwealth of
     Massachusetts, as the Trustee shall determine.  Notice of every
     meeting of the Noteholders, setting forth the time and the place
     of such meeting and in general terms the action proposed to be
     taken at such meeting, shall be mailed not less than 30 nor more
     than 60 days prior to the date fixed for the meeting to such
     Noteholders at their addresses as such addresses appear in the
     Note Register.  For the purpose of determining Noteholders
     entitled to notice of any meeting of Noteholders, the Trustee
     shall fix in advance a date as the record date for such
     determination, such date to be a business day not more than ten
     days prior to the date of the mailing of such notice as
     hereinabove provided.  Only persons in whose name any Note shall
     be registered in the Note Register at the close of business on a
     record date fixed by the Trustee as aforesaid, or by the Company
     or the Noteholders as in Section 10.3 provided, shall be entitled
     to notice of the meeting of Noteholders with respect to which such
     record date was so fixed.

               Section 10.3  Call of Meeting by Company or Noteholders. 
     In case at any time the Company, pursuant to a resolution of its
     Board of Directors or the holders of at least ten percent in
     aggregate principal amount of the Notes then outstanding, shall
     have requested the Trustee to call a meeting of Noteholders to
     take any action authorized in Section 10.1 by written request
     setting forth in reasonable detail the action proposed to be taken
     at the meeting, and the Trustee shall not have mailed notice of
     such meeting within 20 days after receipt of such request, then
     the Company or the holders of Notes in the amount above specified,
     as the case may be, may fix the record date with respect to, and
     determine the time and the place in said City of Boston for, such
     meeting and may call such meeting to take any action authorized in
     Section 10.1, by mailing notice thereof as provided in Section
     10.2. The record date fixed as provided in the preceding sentence
     shall be set forth in a written notice to the Trustee and shall be
     a business day not less than 15 nor more than 20 days after the
     date on which such notice is sent to the Trustee.

               Section 10.4  Who may Attend and Vote at Meetings.  Only
     persons entitled to receive notice of a meeting of Noteholders and
     their respective proxies duly appointed by an instrument in
     writing shall be entitled to vote at such meeting.  The only
     persons who shall be entitled to be present or to speak at any
     meeting of Noteholders shall be the persons entitled to vote at
     such meeting and their counsel and any representatives of the
     Trustee and its counsel and any representatives of the Company and
     its counsel.  When a determination of Noteholders entitled to vote
     at any meeting of Noteholders has been made as provided in this
     Section, such determination shall apply to any adjournments
     thereof.

               Section 10.5  Manner of Voting at Meetings and Record to
     be Kept.  The vote upon any resolution submitted to any meeting of
     Noteholders shall be by written ballots on each of which shall be
     subscribed the signature of the Noteholder or proxy casting such
     ballot and the identifying number or numbers of the Notes held or
     represented in respect of which such ballot is cast.  The
     permanent chairman of the meeting shall appoint two inspectors of
     votes who shall count all votes cast at the meeting for or against
     any resolution and who shall make and file with the secretary of
     the meeting their verified written reports in duplicate of all
     votes cast at the meeting.  A record in duplicate of the
     proceedings of each meeting of Noteholders shall be prepared by
     the secretary of the meeting and there shall be attached to said
     record the original reports of the inspectors of votes on any vote
     by ballot taken thereat and affidavits by one or more persons
     having knowledge of the facts setting forth a copy of the notice
     of the meeting and showing that said notice was mailed as provided
     in Section 10.2. The record shall show the identifying numbers of
     the Notes voting in favor of or against any resolution.  Each
     counterpart of such record shall be signed and verified by the
     affidavits of the permanent chairman and secretary of the meeting
     and one of the counterparts shall be delivered to the Company and
     the other to the Trustee to be preserved by the Trustee.

               Any counterpart record so signed and verified shall be
     conclusive evidence of the matters therein stated and shall be the
     record referred to in clause (b) of Section 9.1.

               Section 10.6  Exercise of Rights of Trustee and
     Noteholders not to be Hindered or delayed.  Nothing in this
     Article X contained shall be deemed or construed to authorize or
     permit, by reason of any call of a meeting of Noteholders or any
     rights expressly or impliedly conferred hereunder to make such
     call, any hindrance or delay in the exercise of any right or
     rights conferred upon or reserved to the Trustee or to the
     Noteholders under any of the provisions of this Indenture or of
     the Notes.

                               ARTICLE XI

                         SUPPLEMENTAL INDENTURES

               Section 11.1  Supplemental Indentures Without Consent of
     Noteholders.  The Company, when authorized by a Board Resolution,
     and the Trustee may from time to time and at any time enter into
     an indenture or indentures supplemental hereto for one or more of
     the following purposes:

               (a)  to make provision with respect to the conversion
     rights of the holders of Notes pursuant to the requirements of
     Section 15.6;

               (b)  subject to Article IV, to convey, transfer, assign,
     mortgage or pledge to the Trustee as security for the Notes, any
     property or assets;

               (c)  to evidence the succession of another person to the
     Company, or successive successions, and the assumption by the
     Successor Company of the covenants, agreements and obligations of
     the Company pursuant to Article XII;

               (d)  to add to the covenants of the Company such further
     covenants, restrictions or conditions as the Board of Directors
     and the Trustee shall consider to be for the benefit of the
     holders of Notes and to make the occurrence, or the occurrence and
     continuance, of a default in any such additional covenants,
     restrictions or conditions a default or an Event of Default
     permitting the enforcement of all or any of the several remedies
     provided in this Indenture as herein set forth; provided, however,
     that in respect of any such additional covenant, restriction or
     condition, such supplemental indenture may provide for a
     particular period of grace after default (which period may be
     shorter or longer than that allowed in the case of other defaults)
     or may provide for an immediate enforcement upon such default or
     may limit the remedies available to the Trustee upon such default;

               (e)  to provide for the issuance under this Indenture of
     Notes in coupon form (including Notes registrable as to principal
     only) and to provide for exchangeability of such Notes with the
     Notes issued hereunder in fully registered form and to make all
     appropriate changes for such purpose;

               (f)  to cure any ambiguity or to correct or supplement
     any provision contained herein or in any supplemental indenture
     which may be defective or inconsistent with any other provision
     contained herein or in any supplemental indenture, or to make such
     other provisions in regard to matters or questions arising under
     this Indenture which shall not materially adversely affect the
     interests of the holders of the Notes;

               (g)  to evidence and provide for the acceptance of
     appointment hereunder by a successor Trustee with respect to the
     Notes;

               (h)  to modify, eliminate or add to the provisions of
     this Indenture to such extent as shall be necessary to effect the
     qualifications of this Indenture under the Trust Indenture Act (if
     applicable), or under any similar federal statute hereafter
     enacted (if applicable); or

               (i)  to modify, eliminate or add to the provisions of
     this Indenture to allow for the issuance of one or more Notes in
     global form, in addition to the global Note provided for herein,
     representing beneficial interests in Notes issued outside the
     United States in reliance on Regulation S under the Securities
     Act, with such transfer restrictions and legends as are consistent
     with such Regulation, and to add provisions relating to the
     exchange and transfer of beneficial interests in any Note or Notes
     represented by any such global Note or Notes, any definitive Note
     and any global Note referred to in Section 2.5(b) hereof.

               The Trustee is hereby authorized to join with the
     Company in the execution of any such supplemental indenture, to
     make any further appropriate agreements and stipulations which may
     be therein contained and to accept the conveyance, transfer and
     assignment of any property thereunder, but the Trustee shall not
     be obligated to, but may in its discretion, enter into any
     supplemental indenture which affects the Trustee's own rights,
     duties or immunities under this Indenture or otherwise.

               Any supplemental indenture authorized by the provisions
     of this Section 11.1 may be executed by the Company and the
     Trustee without the consent of the holders of any of the Notes at
     the time outstanding, notwithstanding any of the provisions of
     Section 11.2.

               Section 11.2  Supplemental Indentures with Consent of
     Noteholders.  With the consent (evidenced as provided in Article
     IX) of the holders of not less than a majority in aggregate
     principal amount of the Notes at the time outstanding, the
     Company, when authorized by a Board Resolution, and the Trustee
     may from time to time and at any time enter into an indenture or
     indentures supplemental hereto for the purpose of adding any
     provisions to or changing in any manner or eliminating any of the
     provisions of this Indenture or any supplemental indenture or of
     modifying in any manner the rights of the holders of the Notes;
     provided, however, that no such supplemental indenture shall (i)
     extend the fixed maturity of any Note, or reduce the rate or
     extend the time of payment of interest thereon, or reduce the
     principal amount thereof or premium, if any, thereon or reduce any
     amount payable on redemption thereof, alter the obligation of the
     Company to redeem the Notes at the option of the holder upon the
     occurrence of a Change of Control or impair or affect the right of
     any Noteholder to institute suit for the payment thereof or make
     the principal thereof or interest or premium, if any, thereon
     payable in any coin or currency other than that provided in the
     Notes or impair the right to exchange the Notes for Preferred
     Stock or the right to convert the Notes into Common Stock subject
     to the terms set forth herein, including Sections 15.6 and 17.6,
     without the consent of the holder of each Note so affected or (ii)
     reduce the aforesaid percentage of Notes, the holders of which are
     required to consent to any such supplemental indenture, without
     the consent of the holders of all Notes then outstanding.

               Upon the request of the Company, accompanied by a copy
     of a Board Resolution certified by its Secretary or Assistant
     Secretary authorizing the execution of any such supplemental
     indenture and the Officer's Certificate and Opinion of Counsel
     required by Section 11.5, and upon the filing with the Trustee of
     evidence of the consent of Noteholders as aforesaid, the Trustee
     shall join with the Company in the execution of such supplemental
     indenture unless such supplemental indenture affects the Trustee's
     own rights, duties or immunities under this Indenture or
     otherwise, in which case the Trustee may in its discretion, but
     shall not be obligated to, enter into such supplemental indenture.

               It shall not be necessary for the consent of the
     Noteholders under this Section 11.2 to approve the particular form
     of any proposed supplemental indenture, but it shall be sufficient
     if such consent shall approve the substance thereof.

               Section 11.3  Effect of Supplemental Indentures.  Any
     supplemental indenture executed pursuant to the provisions of this
     Article XI shall comply with the Trust Indenture Act, as then in
     effect, if such supplemental indenture is then required to so
     comply.  Upon the execution of any supplemental indenture pursuant
     to the provisions of this Article XI, this Indenture shall be and
     be deemed to be modified and amended in accordance therewith and
     the respective rights, limitation of rights, obligations, duties
     and immunities under this Indenture of the Trustee, the Company
     and the holders of Notes shall thereafter be determined, exercised
     and enforced hereunder subject in all respects to such
     modifications and amendments and all the terms and conditions of
     any such supplemental indenture shall be and be deemed to be part
     of the terms and conditions of this Indenture for any and all
     purposes.

               Section 11.4  Notation on Notes.  Notes authenticated
     and delivered after the execution of any supplemental indenture
     pursuant to the provisions of this Article XI may bear a notation
     in form approved by the Trustee as to any matter provided for in
     such supplemental indenture.  If the Company or the Trustee shall
     so determine, new Notes so modified as to conform, in the opinion
     of the Trustee and the Board of Directors, to any modification of
     this Indenture contained in any such supplemental indenture may,
     at the Company's expense, be prepared and executed by the Company,
     authenticated by the Trustee (or an authenticating agent duly
     appointed by the Trustee pursuant to Section 16.12) and delivered
     in exchange for the Notes then outstanding, upon surrender of such
     Notes then outstanding.

               Section 11.5  Evidence of Compliance of Supplemental
     Indenture to be Furnished Trustee.  The Trustee shall be furnished
     with and, subject to the provisions of Sections 8.1 and 8.2, may
     rely upon an Officers' Certificate and an Opinion of Counsel as
     conclusive evidence that any supplemental indenture executed
     pursuant hereto complies with the requirements of this Article XI.

                                ARTICLE XII

                   CONSOLIDATION, MERGER, SALE, CONVEYANCE,
                              TRANSFER AND LEASE

               Section 12.1  Company May Consolidate, Etc. on Certain
     Terms.  The Company shall not consolidate with or merge with or
     into, or convey, transfer or lease all or substantially all of its
     assets to any Person unless: (i) either the Company is the
     resulting, surviving or transferee person (the "Successor
     Company") or the Successor Company is a person organized and
     existing under the laws of the United States or any State thereof
     or the District of Columbia, and the Successor Company (if not the
     Company) expressly assumes by a supplemental indenture, executed
     and delivered to the Trustee, in form satisfactory to the Trustee,
     all the obligations of the Company under this Indenture and the
     Notes, including the rights pursuant to Article XV hereof; (ii)
     immediately after giving effect to such transaction, no Event of
     Default has happened and is continuing; and (iii) the Company
     delivers to the Trustee an Officer's Certificate and an Opinion of
     Counsel, each stating that such consolidation, merger or transfer
     and such supplemental indenture (if any) comply with this
     Indenture.

               Section 12.2  Successor Company to Be Substituted.  In
     case of any such consolidation, merger, sale, conveyance, transfer
     or lease and upon the assumption by the Successor Company, by
     supplemental indenture, executed and delivered to the Trustee and
     satisfactory in form to the Trustee, of the due and punctual
     payment of the principal of, premium, if any, and interest on all
     of the Notes and the due and punctual performance of all of the
     covenants and conditions of this Indenture to be performed by the
     Company, such Successor Company shall succeed to and be
     substituted for the Company, with the same effect as if it had
     been named herein as the party of the first part.  Such Successor
     Company thereupon may cause to be signed, and may issue either in
     its own name or in the name of SoftKey International Inc. any or
     all of the Notes issuable hereunder which theretofore shall not
     have been signed by the Company and delivered to the Trustee; and,
     upon the order of such Successor Company instead of the Company
     and subject to all the terms, conditions and limitations in this
     Indenture prescribed, the Trustee shall authenticate and shall
     deliver, or cause to be authenticated and delivered, any Notes
     which previously shall have been signed and delivered by the
     officers of the Company to the Trustee for authentication, and any
     Notes which such Successor Company thereafter shall cause to be
     signed and delivered to the Trustee for that purpose.  All the
     Notes so issued shall in all respects have the same legal rank and
     benefit under this Indenture as the Notes theretofore or
     thereafter issued in accordance with the terms of this Indenture
     as though all of such Notes had been issued at the date of the
     execution hereof. In the event of any such consolidation, merger,
     sale, conveyance, transfer or lease, the person named as the
     "Company" in the first paragraph of this Indenture or any
     successor which shall thereafter have become such in the manner
     prescribed in this Article XII may be dissolved, wound up and
     liquidated at any time thereafter and such person shall be
     released from its liabilities as obligor and maker of the Notes
     and from its obligations under this Indenture.

               In case of any such consolidation, merger, sale,
     conveyance, transfer or lease, such changes in phraseology and
     form (but not in substance) may be made in the Notes thereafter to
     be issued as may be appropriate.

               Section 12.3  Opinion of Counsel to Be Given Trustee. 
     The Trustee subject to Sections 8.1 and 8.2, shall receive an
     Officers' Certificate and an Opinion of Counsel as conclusive
     evidence that any such consolidation, merger, sale, conveyance,
     transfer or lease and any such assumption complies with the
     provisions of this Article XII.

                   SATISFACTION AND DISCHARGE OF INDENTURE;

     of the Notes.

               (a)  The Company may, at its option by Board Resolution,
     at any time, with respect to the Notes, elect to have either
     paragraph (b) or paragraph (c) below be applied to the outstanding
     Notes upon compliance with the conditions set forth in paragraph
     (d).

               (b)  Upon the Company's exercise under paragraph (a) of
     the option applicable to this paragraph (b), the Company shall be
     deemed to have been released and discharged from its obligations
     with respect to the outstanding Notes on the date the conditions
     set forth below are satisfied (hereinafter, "legal defeasance"). 
     For this purpose, such legal defeasance means that the Company
     shall be deemed to have paid and discharged the entire
     indebtedness represented by the outstanding Notes, which shall
     thereafter be deemed to be "outstanding" only for the purposes of
     the Sections of and matters under this Indenture referred to in
     (i) and (ii) below and to have satisfied all its other obligations
     under such Notes and this Indenture insofar as such Notes are
     concerned, except for the following which shall survive until
     otherwise terminated or discharged hereunder: (i) the rights of
     holders of outstanding Notes to receive solely from the trust fund
     described in paragraph (d) below and as more fully set forth in
     such paragraph, payments in respect of the principal of, premium,
     if any, and interest on such Notes when such payments are due,
     (ii) obligations listed in Section 13.3 and (iii) the obligations
     of the Company pursuant to Section 5.6.

               (c)  Upon the Company's exercise under paragraph (a) of
     the option applicable to this paragraph (c), the Company shall be
     released and discharged from its obligations under any covenant
     contained in Article XII and in Sections 3.5, 5.3, 5.4, 5.5 and
     5.7 with respect to the outstanding Notes on and after the date
     the conditions set forth in paragraph (d) are satisfied
     (hereinafter, "covenant defeasance"), and the Notes shall
     thereafter be deemed to be not "outstanding" for the purpose of
     any direction, waiver, consent or declaration or act of Holders
     (and the consequences of any thereof) in connection with such
     covenants, but shall continue to be deemed "outstanding" for all
     other purposes hereunder.  For this purpose, such covenant
     defeasance means that, with respect to the outstanding Notes, the
     Company may omit to comply with and shall have no liability in
     respect of any term, condition or limitation set forth in any such
     covenant, whether directly or indirectly, by reason of any
     reference elsewhere herein to any such covenant or by reason of
     any reference in any such covenant to any other provision herein
     or in any other document, and such omission to comply shall not
     constitute a Default or an Event of default under Section 7.1(c),
     but, except as specified above, the remainder of this Indenture
     and such Notes shall be unaffected thereby.

          (d)  The following shall be the conditions to application of
     either paragraph (b) or paragraph (c) above to the outstanding
     Notes:

                    (i)  The Company shall have irrevocably deposited
          in trust with the Trustee, pursuant to an irrevocable trust
          and security agreement in form and substance satisfactory to
          the Trustee, cash or U.S. Government Obligations maturing as
          to principal and interest at such times, or a combination
          thereof, in such amounts as are sufficient, without
          consideration of the reinvestment of such interest and after
          payment of all federal, state and local taxes or other
          charges or assessments in respect thereof payable by the
          Trustee, in the opinion of a nationally recognized firm of
          independent public accountants expressed in a written
          certification thereof (in form and substance reasonably
          satisfactory to the Trustee) delivered to the Trustee, to pay
          the principal of, premium, if any, and interest on the
          outstanding Notes on the dates on which any such payments are
          due and payable in accordance with the terms of this
          Indenture and of the Notes;

               (ii)  (A) No Event of Default shall have occurred or be
          continuing on the date of such deposit, and (B) no Default or
          Event of Default under Section 7.1(d) or 7.1(e) shall occur
          on or before the 123rd day after the date of such deposit;

               (iii)  Such deposit will not result in a Default under
          this Indenture or a breach or violation of, or constitute a
          default under, any other instrument or agreement to which the
          Company is a party or by which it or its property is bound;

               (iv) In the case of a legal defeasance under paragraph
          (b) above, the Company has delivered to the Trustee an
          Opinion of Counsel stating that (A) the Company has received
          from, or there has been published by, the Internal Revenue
          Service a ruling or (B) since the date of this Indenture,
          there has been a change in the applicable federal income tax
          law, in either case to the effect that, and based thereon
          such opinion shall confirm that, the holders of the Notes
          will not recognize income, gain or loss for federal income
          tax purposes as a result of such deposit, defeasance and
          discharge and will be subject to federal income tax on the
          same amounts and in the same manner and at the same times as
          would have been the case if such deposit, defeasance and
          discharge had not occurred; and, in the case of a covenant
          defeasance under paragraph (c) above, the Company shall
          deliver to the Trustee an Officers' Certificate and an
          Opinion of Counsel, in form and substance reasonably
          satisfactory to the Trustee, to the effect that holders of
          the Notes will not recognize income, gain or loss for federal
          income tax purposes as a result of such deposit and
          defeasance and will be subject to federal income tax on the
          same amounts, in the same manner and at the same times as
          would have been the case if such deposit and defeasance had
          not occurred;

               (v)  The holders shall have a perfected security
          interest under applicable law in the cash or U.S. Government
          Obligations deposited pursuant to Section 13(d)(i) above;

               (vi) The Company shall have delivered to the Trustee an
          Opinion of Counsel, in form and substance reasonably
          satisfactory to the Trustee, to the effect that, after the
          passage of 123 days following the deposit, the trust funds
          will not be subject to any applicable bankruptcy, insolvency,
          reorganization or similar law affecting creditors' rights
          generally;

               (vii) Such defeasance shall not cause the Trustee to
          have a conflicting interest with respect to any securities of
          the Company; and

               (viii)  The Company has delivered to the Trustee an
          Officers' Certificate and an Opinion of Counsel, each stating
          that all conditions precedent specified herein relating to
          the defeasance contemplated by this Section 13.1 have been
          complied with; 

     provided, however, that no deposit under clause (d)(i) above shall
     be effective to terminate the obligations of the Company under the
     Notes or this Indenture prior to 123 days following any such
     deposit.

               Section 13.2  Termination of Obligations upon
     Cancellation of the Notes.  In addition to the Company's rights
     under Section 13.1, the Company may terminate all of its
     obligations under this Indenture (subject to Section 13.3 and any
     obligations of the Company under Section 5.6 with respect to any
     Common Stock issued upon conversion of the Notes or any Preferred
     Stock issued upon exchange of the Notes) when:

               (a)  (i)  all Notes theretofore authenticated and
          delivered (other than Notes which have been destroyed, lost
          or stolen and which have been replaced or paid as provided in
          Section 2.6) have been delivered to the Trustee for
          cancellation;

               (ii) the Company has paid or caused to be paid all other
          sums payable hereunder and under the Notes by the Company;
          and

               (iii)  the Company has delivered to the Trustee an
          Officers' Certificate, stating that all conditions precedent
          specified herein relating to the satisfaction and discharge
          of this Indenture have been complied with; or

               (b)  (i) the Notes not previously delivered to the
          Trustee for cancellation will have become due and payable or
          are by their terms to become due and payable within one year
          or are to be called for redemption under arrangements
          satisfactory to the Trustee upon delivery of notice; (ii) the
          Company will have irrevocably deposited with the Trustee, as
          trust funds, cash, in an amount sufficient to pay principal
          of and interest on the outstanding Notes, to maturity or
          redemption, as the case may be; (iii) such deposit will not
          result in a breach or violation of, or constitute a default
          under, any agreement or instrument pursuant to which the
          Company is a party or by which it or its property is bound;
          and (iv) and the Company has delivered to the Trustee an
          Officers' Certificate and an Opinion of Counsel, each stating
          that all conditions related to such defeasance have been
          complied with.

               Section 13.3  Survival of Certain Obligations. 
     Notwithstanding the satisfaction and discharge of this Indenture
     and of the Notes referred to in Section 13.1 or 13.2, the
     respective obligations of the Company and the Trustee under
     Sections 2.3, 2.4, 2.5, 2.6, 2.8, 2.9, 5.2, 6.1, 7.4, 7.9, 8.6,
     8.10, 13.5, 13.6 and 13.7 shall survive until the Notes are no
     longer outstanding, and thereafter, the obligations of the Company
     and the Trustee under Sections 7.9, 8.6, 13.5, 13.6 and 13.7 shall
     survive.  Nothing contained in this Article XIII shall abrogate
     any of the rights, obligations or duties of the Trustee under this
     Indenture.

               Section 13.4  Acknowledgment of Discharge by Trustee. 
     Subject to Section 13.7, after (i) the conditions of Section 13.1
     or 13.2 have been satisfied, (ii) the Company has paid or caused
     to be paid all other sums payable hereunder by the Company and
     (iii) the Company has delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all
     conditions precedent referred to in clause (i) above relating to
     the satisfaction and discharge of this Indenture have been
     complied with, the Trustee upon written request shall acknowledge
     in writing the discharge of the Company's obligations under this
     Indenture except for those surviving obligations specified in
     Section 13.3.

               Section 13.5  Application of Trust Assets.  The Trustee
     shall hold any cash or U.S. Government Obligations deposited with
     it in the irrevocable trust established pursuant to Section 13.1
     or 13.2, as the case may be.  The Trustee shall apply the
     deposited cash or the U.S. Government Obligations, together with
     earnings thereon in accordance with this Indenture and the terms
     of the irrevocable trust agreement established pursuant to Section
     13.1 or 13.2, as the case may be, to the payment of principal of,
     premium, if any, and interest on the Notes.  The cash or U.S.
     Government Obligations so held in trust and deposited with the
     Trustee in compliance with Section 13.1 or 13.2, as the case may
     be, shall not be part of the trust estate under this Indenture,
     but shall constitute a separate trust fund for the benefit of all
     holders entitled thereto.  Except as specifically provided herein,
     the Trustee shall not be requested to invest any amounts held by
     it for the benefit of the holders or pay interest on uninvested
     amounts to any holder.

               Section 13.6  Repayment to the Company; Unclaimed Money. 
     Upon termination of the trust established pursuant to Section 13.1
     or 13.2, as the case may be, the Trustee shall promptly pay to the
     Company upon request any excess cash or U.S. Government
     Obligations held by them.  Additionally, if amounts for the
     payment of principal, premium, if any, or interest remains
     unclaimed for six years, the Trustee will pay such amounts back to
     the Company forthwith.  Thereafter, all liability of the Trustee
     with respect to such amounts shall cease.

               Subject to applicable laws governing escheat of such
     property, the Trustee shall pay to the Company upon request, and,
     if applicable, in accordance with the irrevocable trust
     established pursuant to Section 13.1 or 13.2, any cash or U.S.
     Government Obligations held by them for the payment of principal
     of, premium, if any, or interest on the Notes that remain
     unclaimed for six years after the date on which such payment shall
     have become due.  After payment to the Company, Holders entitled
     to such payment must look to the Company for such payment as
     general creditors unless an applicable abandoned property law
     designates another person.

               Section 13.7  Reinstatement.  If the Trustee is unable
     to apply any cash or U.S. Government Obligations in accordance
     with Section 13.1 or 13.2 by reason of any legal proceeding or by
     reason of any order or judgment of any court or governmental
     authority enjoining, restraining or otherwise prohibiting such
     application, the Company's obligations under this Indenture and
     the Notes shall be revived and reinstated as though no deposit had
     occurred pursuant to Section 13.1 or 13.2 until such time as the
     Trustee is permitted to apply all such cash or U.S. Government
     Obligations in accordance with Section 13.1 or 13.2, as the case
     may be; provided that if the Company makes any payment of
     principal of, premium, if any, or interest on any Notes following
     the reinstatement of its obligations, the Company shall be
     subrogated to the rights of the Holders of such Notes to receive
     such payment from the amounts held by the Trustee.

                                 ARTICLE XIV

                     IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                              OFFICERS AND DIRECTORS

               Section 14.1  Indenture and Notes Solely Corporate
     Obligations.  No recourse for the payment of the principal of, or
     premium, if any, or interest on any Note, or for any claim based
     thereon or otherwise in respect thereof, and no recourse under or
     upon any obligation, covenant or agreement of the Company in this
     Indenture or in any supplemental indenture or in any Note, or
     because of the creation of any indebtedness represented thereby,
     shall be had against any incorporator, stockholder, officer or
     director, as such, past, present or future, of the Company or of
     any successor entity, either directly or through the Company or
     any successor entity, whether by virtue of any constitution,
     statute or rule of law, or by the enforcement of any assessment or
     penalty or otherwise; it being expressly understood that all such
     liability is hereby expressly waived and released as a condition
     of, and as a consideration for, the execution of this Indenture
     and the issue of the Notes.

                                 ARTICLE XV

                             CONVERSION OF NOTES

               Section 15.1  Right to Convert.  Subject to and upon
     compliance with the provisions of this Indenture, the holder of
     any Note shall have the right, at his option, at any time prior to
     the close of business on November 1, 2000 (except that, with
     respect to any Note or portion of a Note which shall be called for
     redemption or delivered for repurchase, such right shall
     terminate, except as provided in the fourth paragraph of Section
     15.2, at the close of business on the last Trading Day prior to
     the date fixed for redemption of such Note or portion of a Note
     unless the Company shall default in payment due upon redemption
     thereof) to convert the principal amount of any such Note, or any
     portion of such principal amount which is $1,000 or an integral
     multiple thereof, into that number of fully paid and nonassessable
     shares of Common Stock (as such shares shall then be constituted)
     obtained by dividing the principal amount of the Note or portion
     thereof surrendered for conversion by the Conversion Price in
     effect at such time, by surrender of the Note so to be converted
     in whole or in part in the manner provided in Section 15.2. A
     holder of Notes is not entitled to any rights of a holder of
     Common Stock until such holder has converted his Notes to Common
     Stock, and only to the extent such Notes are deemed to have been
     converted to Common Stock under this Article XV.

               Section 15.2  Exercise of Conversion Privilege; Issuance
     of Common Stock on Conversion; No Adjustment for Interest or
     Dividends.  In order to exercise the conversion privilege with
     respect to any Note in definitive form, the holder of any such
     Note to be converted in whole or in part shall surrender such
     Note, duly endorsed, at an office or agency maintained by the
     Company pursuant to Section 5.2, accompanied by the funds, if any,
     required by the penultimate paragraph of this Section 15.2, and
     shall give written notice of conversion in the form provided on
     the Notes (or such other notice which is acceptable to the
     Company) to the office or agency that the holder elects to convert
     such Note or the portion thereof specified in said notice.  Such
     notice shall also state the name or names (with address) in which
     the certificate or certificates for shares of Common Stock which
     shall be issuable on such conversion shall be issued and shall be
     accompanied by transfer taxes, if required pursuant to Section
     15.7. Each such Note surrendered for conversion shall, unless the
     shares issuable on conversion are to be issued in the same name as
     the registration of such Note, be duly endorsed by, or be
     accompanied by instruments of transfer in form satisfactory to the
     Company duly executed by, the holder or his duly authorized
     attorney.

               In order to exercise the conversion privilege with
     respect to any interest in a Note in global form, the beneficial
     holder must complete the appropriate instruction form for
     conversion pursuant to the Depositary's book-entry conversion
     program and follow the other procedures set forth in such program.

               As promptly as practicable after satisfaction of the
     requirements for conversion set forth above, subject to compliance
     with any restrictions on transfer if shares issuable on conversion
     are to be issued in a name other than that of the Noteholder (as
     if such transfer were a transfer of the Note or Notes (or portion
     thereof) so converted), the Company shall issue and shall deliver
     to such holder at the office or agency maintained by the Company
     for such purpose pursuant to Section 5.2, a certificate or
     certificates for the number of full shares issuable upon the
     conversion of such Note or portion thereof in accordance with the
     provisions of this Article XV and a check or cash in respect of
     any fractional interest in respect of a share of Common Stock
     arising upon such conversion, as provided in Section 15.3. In case
     any Note of a denomination greater than $1,000 shall be
     surrendered for partial conversion, and subject to Section 2.3,
     the Company shall execute and the Trustee shall authenticate and
     deliver to the holder of the Note so surrendered, without charge
     to him, a new Note or Notes in authorized denominations in an
     aggregate principal amount equal to the unconverted portion of the
     surrendered Note.

               Each conversion shall be deemed to have been effected as
     to any such Note (or portion thereof) on the date on which the
     requirements set forth above in this Section 15.2 have been
     satisfied as to such Note (or portion thereof), and the person in
     whose name any certificate or certificates for shares of Common
     Stock shall be issuable upon such conversion shall be deemed to
     have become on said date the holder of record of the shares
     represented thereby; provided, however, that any such surrender on
     any date when the stock transfer books of the Company shall be
     closed shall constitute the person in whose name the certificates
     are to be issued as the record holder thereof for all purposes on
     the next succeeding day on which such stock transfer books are
     open, but such conversion shall be at the Conversion Price in
     effect on the date upon which such Note shall have been
     surrendered.

               Any Note or portion thereof surrendered for conversion
     during the period from the close of business on the record date
     for any interest payment date through the close of business on the
     Trading Day next preceding such interest payment date shall
     (unless such Note or portion thereof being converted shall have
     been called for redemption on a date in such period) be
     accompanied by payment, in funds acceptable to the Company, of an
     amount equal to the interest otherwise payable on such interest
     payment date on the principal amount being converted; provided,
     however, that no such payment need be made if there shall exist at
     the time of conversion a default in the payment of interest on the
     Notes.  An amount equal to such payment shall be paid by the
     Company on such interest payment date to the holder of such Note
     at the close of business on such record date; provided, however,
     that if the Company shall default in the payment of interest on
     such interest payment date, such amount shall be paid to the
     person who made such required payment.  Except as provided above
     in this Section 15.2, no adjustment shall be made for interest
     accrued on any Note converted or for dividends on any shares
     issued upon the conversion of such Note as provided in this
     Article.

               Upon the conversion of an interest in a Note in global
     form, the Trustee, or the Custodian at the direction of the
     Trustee, shall make an adjustment on its records with respect to
     such Note in global form as to the reduction in the principal
     amount represented thereby.

               Section 15.3  Cash Payments in Lieu of Fractional
     Shares.  No fractional shares of Common Stock or scrip
     representing fractional shares shall be issued upon conversion of
     Notes.  If more than one Note shall be surrendered for conversion
     at one time by the same holder, the number of full shares which
     shall be issuable upon conversion shall be computed on the basis
     of the aggregate principal amount of the Notes (or specified
     portions thereof to the extent permitted hereby) so surrendered. 
     If any fractional share of stock would be issuable upon the
     conversion of any Note or Notes, the Company shall make an
     adjustment therefor in cash at the current market value thereof. 
     The current market value of a share of Common Stock shall be the
     Closing Price on the first Trading Day immediately preceding the
     day on which the Notes (or specified portions thereof) are deemed
     to have been converted and such Closing Price shall be determined
     as provided in Section 15.5(g).

               Section 15.4  Conversion Price.  The conversion price
     shall be as specified in the forms of Notes (herein called the
     "Conversion Price") attached as Exhibits A and B hereto, subject
     to adjustment as provided in this Article XV.

               Section 15.5  Adjustment of Conversion Price.  The
     Conversion Price shall be adjusted from time to time by the
     Company as follows:

               (a)  In case the Company shall hereafter pay a dividend
     or make a distribution to all holders of the outstanding Common
     Stock in shares of Common Stock, the Conversion Price in effect at
     the opening of business on the date following the date fixed for
     the determination of stockholders entitled to receive such
     dividend or other distribution shall be reduced by multiplying
     such Conversion Price by a fraction the numerator of which shall
     be the number of shares of Common Stock outstanding at the close
     of business on the Record Date (as defined in Section 15.5(g))
     fixed for such determination and the denominator of which shall be
     the sum of such number of shares and the total number of shares
     constituting such dividend or other distribution, such reduction
     to become effective immediately after the opening of business on
     the day following the Record Date.  The Company will not pay any
     dividend or make any distribution on shares of Common Stock held
     in the treasury of the Company.

               (b)  In case the Company shall issue rights or warrants
     to all holders of its outstanding shares of Common Stock entitling
     them (for a period expiring within 45 days after the date fixed
     for determination of stockholders entitled to receive such rights
     or warrants) to subscribe for or purchase shares of Common Stock
     at a price per share less than the Current Market Price (as
     defined in Section 15.5(g)) on the Record Date fixed for
     determination of stockholders entitled to receive such rights or
     warrants, the Conversion Price shall be adjusted so that the same
     shall equal the price determined by multiplying the Conversion
     Price in effect at the opening of business on the date after the
     Record Date by a fraction the numerator of which shall be the
     number of shares of Common Stock outstanding at the close of
     business on the Record Date plus the number of shares which the
     aggregate offering price of the total number of shares so offered
     would purchase at such Current Market Price, and the denominator
     of which shall be the number of shares of Common Stock outstanding
     on the close of business on the Record Date plus the total number
     of additional shares of Common Stock so offered for subscription
     or purchase.  Such adjustment shall become effective immediately
     after the opening of business on the day following the Record Date
     fixed for determination of stockholders entitled to receive such
     rights or warrants.  To the extent that shares of Common Stock are
     not delivered after the expiration or termination of such rights
     or warrants, the Conversion Price shall be readjusted to the
     Conversion Price which would then be in effect had the adjustments
     made upon the issuance of such rights or warrants been made on the
     basis of delivery of only the number of shares of Common Stock
     actually delivered.  In the event that such rights or warrants are
     not so issued, the Conversion Price shall again be adjusted to be
     the Conversion Price which would then be in effect if such date
     fixed for the determination of stockholders entitled to receive
     such rights or warrants had not been fixed.  In determining
     whether any rights or warrants entitle the holders to subscribe
     for or purchase shares of Common Stock at less than such Current
     Market Price, and in determining the aggregate offering price of
     such shares of Common Stock, there shall be taken into account any
     consideration received for such rights or warrants, the value of
     such consideration, if other than cash, to be determined by the
     Board of Directors.

               (c)  In case outstanding shares of Common Stock shall be
     subdivided into a greater number of shares of Common Stock, the
     Conversion Price in effect at the opening of business on the day
     following the day upon which such subdivision becomes effective
     shall be proportionately reduced, and conversely, in case
     outstanding shares of Common Stock shall be combined into a
     smaller number of shares of Common Stock, the Conversion Price in
     effect at the opening of business on the day following the day
     upon which such combination becomes effective shall be
     proportionately increased, such reduction or increase, as the case
     may be, to become effective immediately after the opening of
     business on the day following the day upon which such subdivision
     or combination becomes effective.

               (d)  In case the Company shall, by dividend or
     otherwise, distribute to all holders of its Common Stock shares of
     any class of capital stock of the Company (other than any
     dividends or distributions to which Section 15.5(a) applies) or
     evidences of its indebtedness or assets (including securities, but
     excluding any rights or warrants referred to in Section 15.5(b),
     and excluding any dividend or distribution (x) in connection with
     the liquidation, dissolution or winding-up of the Company, whether
     voluntary or involuntary, (y) exclusively in cash or (z) referred
     to in Section 15.5(a) (any of the foregoing hereinafter in this
     Section 15.5(d) called the "Securities"), then, in each such case,
     the Conversion Price shall be reduced so that the same shall be
     equal to the price determined by multiplying the Conversion Price
     in effect immediately prior to the close of business on the Record
     Date (as defined in Section 15.5(g)) with respect to such
     distribution by a fraction of which the numerator shall be the
     Current Market Price (determined as provided in Section 15.5(g))
     on such date less the fair market value (as determined by the
     Board of Directors, whose determination shall be conclusive and
     described in a Board Resolution) on such date of the portion of
     the Securities so distributed applicable to one share of Common
     Stock and the denominator shall be such Current Market Price, such
     reduction to become effective immediately prior to the opening of
     business on the day following the Record Date; provided, however,
     that in the event the then fair market value (as so determined) of
     the portion of the Securities so distributed applicable to one
     share of Common Stock is equal to or greater than the Current
     Market Price on the Record Date, in lieu of the foregoing
     adjustment, adequate provision shall be made so that each
     Noteholder shall have the right to receive upon conversion the
     amount of Securities such holder would have received had such
     holder converted each Note on such date.  In the event that such
     dividend or distribution is not so paid or made, the Conversion
     Price shall again be adjusted to be the Conversion Price which
     would then be in effect if such dividend or distribution had not
     been declared.  If the Board of Directors determines the fair
     market value of any distribution for purposes of this Section
     15.5(d) by reference to the actual or when issued trading market
     for any securities comprising all or part of such distribution, it
     must in doing so consider the prices in such market over the same
     period used in computing the Current Market Price pursuant to
     Section 15.5(g) to the extent possible.

               Notwithstanding the foregoing provisions of this Section
     15.5(d), no adjustment shall be made hereunder for any
     distribution of Securities if the Company makes proper provision
     so that each Noteholder who converts such Note (or any portion
     thereof) after the date fixed for determination of stockholders
     entitled to receive such distribution shall be entitled to receive
     upon such conversion, in addition to the shares of Common Stock
     issuable upon such conversion, the amount and kind of Securities
     that such holder would have been entitled to receive if such
     holder had, immediately prior to such determination date,
     converted such Note into Common Stock; provided that, with respect
     to any Securities that are convertible, exchangeable or
     exercisable, the foregoing provision shall only apply to the
     extent (and so long as) the Securities receivable upon conversion
     of such Note would be convertible, exchangeable or exercisable, as
     applicable, without any loss of rights or privileges for a period
     of at least 60 days following conversion of such Note.

               Rights or warrants distributed by the Company to all
     holders of Common Stock entitling the holders thereof to subscribe
     for or purchase shares of the Company's capital stock (either
     initially or under certain circumstances), which rights or
     warrants, until the occurrence of a specified event or events
     ("Trigger Event"): (i) are deemed to be transferred with such
     shares of Common Stock, (ii) are not exercisable and (iii) are
     also issued in respect of future issuances of Common Stock, shall
     not be deemed distributed for purposes of this Section 15.5(d)
     (and no adjustment to the Conversion Price under Section 15.5(d)
     will be required) until the occurrence of the earliest Trigger
     Event.  In addition, in the event of any distribution of rights or
     warrants, or any Trigger Event with respect thereto, that shall
     have resulted in an adjustment to the Conversion Price under this
     Section 15.5(d), (1) in the case of any such rights or warrants
     which shall all have been redeemed or repurchased without exercise
     by any holders thereof, the Conversion Price shall be readjusted
     upon such final redemption or repurchase to give effect to such
     distribution or Trigger Event, as the case may be, as though it
     were a cash distribution, equal to the per share redemption or
     repurchase price received by a holder of Common Stock with respect
     to such rights or warrants (assuming such holder had retained such
     rights or warrants), made to all holders of Common Stock as of the
     date of such redemption or repurchase, and (2) in the case of such
     rights or warrants all of which shall have expired or been
     terminated without exercise by any holder thereof, the Conversion
     Price shall be readjusted as if such issuance had not occurred.

               For purposes of this Section 15.5(d) and Sections
     15.5(a) and (b), any dividend or distribution to which this
     Section 15.5(d) is applicable that also includes shares of Common
     Stock, or rights or warrants to subscribe for or purchase shares
     of Common Stock (or both), shall be deemed instead to be (1) a
     dividend or distribution of the evidences of indebtedness, assets
     or shares of capital stock other than such shares of Common Stock
     or rights or warrants (and any Conversion Price reduction required
     by this Section 15.5(d) with respect to such dividend or
     distribution shall then be made) immediately followed by (2) a
     dividend or distribution of such shares of Common Stock or such
     rights or warrants (and any further Conversion Price reduction
     required by Sections 15.5(a) and (b) with respect to such dividend
     or distribution shall then be made, except (A) the Record Date of
     such dividend or distribution shall be substituted as "the date
     fixed for the determination of stockholders entitled to receive
     such dividend or other distribution" and "the date fixed for such
     determination" within the meaning of Sections 15.5(a) and (b) and
     (B) any shares of Common Stock included in such dividend or
     distribution shall not be deemed "outstanding at the close of
     business on the date fixed for such determination" within the
     meaning of Section 15.5(a).

               (e)  In case the Company shall, by dividend or
     otherwise, distribute to all holders of its Common Stock cash
     (excluding any cash that is distributed upon a merger or
     consolidation to which Section 15.6 applies or as part of a
     distribution referred to in Section 15.5(d)) in an aggregate
     amount that, combined together with (1) the aggregate amount of
     any other such distributions to all holders of its Common Stock
     made exclusively in cash within the twelve (12) months preceding
     the date of payment of such distribution, and in respect of which
     no adjustment pursuant to this Section 15.5(e) has been made, and
     (2) the aggregate of any cash plus the fair market value (as
     determined by the Board of Directors, whose determination shall be
     conclusive and described in a Board Resolution) of consideration
     payable in respect of any tender offer, by the Company or any of
     its subsidiaries for all or any portion of the Common Stock
     concluded within the twelve (12) months preceding the date of
     payment of such distribution, and in respect of which no
     adjustment pursuant to Section 15.5(f) has been made, exceeds
     20.0% of the product of the Current Market Price (determined as
     provided in Section 15.5(g)) on the Record Date with respect to
     such distribution times the number of shares of Common Stock
     outstanding on such date, then, and in each such case, immediately
     after the close of business on such date, unless the Company
     elects to reserve such cash for distribution to the holders of the
     Notes upon the conversion of the Notes so that any such holder
     converting Notes will receive upon such conversion, in addition to
     the shares of Common Stock to which such holder is entitled, the
     amount of cash which such holder would have received if such
     holder had, immediately prior to the Record Date for such
     distribution of cash, converted its Notes into Common Stock, the
     Conversion Price shall be reduced so that the same shall equal the
     price determined by multiplying the Conversion Price in effect
     immediately prior to the close of business on such date by a
     fraction (i) the numerator of which shall be equal to the Current
     Market Price on the Record Date less an amount equal to the
     quotient of (x) the excess of such combined amount over such 20.0%
     and (y) the number of shares of Common Stock outstanding on the
     Record Date and (ii) the denominator of which shall be equal to
     the Current Market Price on such date; provided, however, that in
     the event the portion of the cash so distributed applicable to one
     share of Common Stock is equal to or greater than the Current
     Market Price of the Common Stock on the Record Date, in lieu of
     the foregoing adjustment, adequate provision shall be made so that
     each Noteholder shall have the right to receive upon conversion
     the amount of cash such holder would have received had such holder
     converted each Note on the Record Date.  In the event that such
     dividend or distribution is not so paid or made, the Conversion
     Price shall again be adjusted to be the Conversion Price which
     would then be in effect if such dividend or distribution had not
     been declared.

               (f)  In case a tender offer made by the Company or any
     of its subsidiaries for all or any portion of the Common Stock
     shall expire and such tender offer (as amended upon the expiration
     thereof) shall require the payment to stockholders (based on the
     acceptance (up to any maximum specified in the terms of the tender
     offer) of Purchased Shares (as defined below)) of an aggregate
     consideration having a fair market value (as determined by the
     Board of Directors, whose determination shall be conclusive and
     described in a Board Resolution) that combined together with (1)
     the aggregate of the cash plus the fair market value (as
     determined by the Board of Directors, whose determination shall be
     conclusive and described in a Board Resolution), as of the
     expiration of such tender offer, of consideration payable in
     respect of any other tender offer, by the Company or any of its
     subsidiaries for all or any portion of the Common Stock expiring
     within the twelve (12) months preceding the expiration of such
     tender offer, and in respect of which no adjustment pursuant to
     this paragraph (f) has been made, and (2) the aggregate amount of
     any distributions to all holders of the Company's Common Stock
     made exclusively in cash within twelve (12) months preceding the
     expiration of such tender offer, and in respect of which no
     adjustment pursuant to paragraph (e) of this Section has been
     made, exceeds 20.0% of the product of the Current Market Price
     (determined as provided in paragraph (g) of this Section) as of
     the last time (the "Expiration Time") tenders could have been made
     pursuant to such tender offer (as it may be amended) times the
     number of shares of Common Stock outstanding (including any
     tendered shares) on the Expiration Time, then, and in each such
     case, immediately prior to the opening of business on the day
     after the date of the Expiration Time, the Conversion Price shall
     be adjusted so that the same shall equal the price determined by
     multiplying the Conversion Price in effect immediately prior to
     close of business on the date of the Expiration Time by a fraction
     of which the numerator shall be the number of shares of Common
     Stock outstanding (including any tendered shares) on the
     Expiration Time multiplied by the Current Market Price of the
     Common Stock on the Trading Day next succeeding the Expiration
     Time and the denominator shall be the sum of (x) the fair market
     value (determined as aforesaid) of the aggregate consideration
     payable to stockholders based on the acceptance (up to any maximum
     specified in the terms of the tender offer) of all shares validly
     tendered and not withdrawn as of the Expiration Time (the shares
     deemed so accepted, up to any such maximum, being referred to as
     the "Purchased Shares") and (y) the product of the number of
     shares of Common Stock outstanding (less any Purchased Shares) on
     the Expiration Time and the Current Market Price of the Common
     Stock on the Trading Day next succeeding the Expiration Time, such
     reduction to become effective immediately prior to the opening of
     business on the day following the Expiration Time.  In the event
     that the Company is obligated to purchase shares pursuant to any
     such tender offer, but the Company is permanently prevented by
     applicable law from effecting any such purchases or all such
     purchases are rescinded, the Conversion Price shall again be
     adjusted to be the Conversion Price which would then be in effect
     if such tender offer had not been made.

               (g)  For purposes of this Indenture, the following terms
     shall have the meaning indicated:

               (1)  "Closing Price" with respect to any securities on
          any day shall mean the closing sale price regular way on such
          day or, in case no such sale takes place on such day, the
          average of the reported closing bid and asked prices, regular
          way, in each case on the New York Stock Exchange, or, if such
          security is not listed or admitted to trading on such
          Exchange, on the principal national security exchange or
          quotation system on which such security is quoted or listed
          or admitted to trading, or, if not quoted or listed or
          admitted to trading on any national securities exchange or
          quotation system, the average of the closing bid and asked
          prices of such security on the over-the-counter market on the
          day in question as reported by the National Quotation Bureau
          Incorporated, or a similar generally accepted reporting
          service, or if not so available, in such manner as furnished
          by any New York Stock Exchange member firm selected from time
          to time by the Board of Directors for that purpose, or a
          price determined in good faith by the Board of Directors
          whose determination shall be conclusive and described in a
          Board Resolution.

               (2)  "Current Market Price" shall mean the average of
          the daily Closing Prices per share of Common Stock for the
          ten consecutive Trading Days immediately prior to the date in
          question; provided, however, that (1) if the "ex" date (as
          hereinafter defined) for any event (other than the issuance
          or distribution or Change of Control requiring such
          computation) that requires an adjustment to the Conversion
          Price pursuant to Section 15.5(a), (b), (c), (d), (e) or (f)
          occurs during such ten consecutive Trading Days, the Closing
          Price for each Trading Day prior to the "ex" date for such
          other event shall be adjusted by multiplying such Closing
          Price by the same fraction by which the Conversion Price is
          so required to be adjusted as a result of such other event,
          (2) if the "ex" date for any event (other than the issuance,
          distribution or Change of Control requiring such computation)
          that requires an adjustment to the Conversion Price pursuant
          to Section 15.5(a), (b), (c), (d), (e) or (f) occurs on or
          after the "ex" date for the issuance or distribution
          requiring such computation and prior to the day in question,
          the Closing Price for each Trading Day on and after the "ex"
          date for such other event shall be adjusted by multiplying
          such Closing Price by the reciprocal of the fraction by which
          the Conversion Price is so required to be adjusted as a
          result of such other event and (3) if the "ex" date for the
          issuance, distribution or Change of Control requiring such
          computation is prior to the day in question, after taking
          into account any adjustment required pursuant to clause (1)
          or (2) of this proviso, the Closing Price for each Trading
          Day on or after such "ex" date shall be adjusted by adding
          thereto the amount of any cash and the fair market value (as
          determined by the Board of Directors in a manner consistent
          with any determination of such value for purposes of Section
          15.5(d) or (f), whose determination shall be conclusive and
          described in a Board Resolution) of the evidences of
          indebtedness, shares of capital stock or assets being
          distributed applicable to one share of Common Stock as of the
          close of business on the day before such "ex" date.  For
          purposes of any computation under Section 15.5(f), the
          Current Market Price of the Common Stock on any date shall be
          deemed to be the average of the daily Closing Prices per
          share of Common Stock for such day and the next two
          succeeding Trading Days; provided, however, that if the "ex"
          date for any event (other than the tender or exchange offer
          requiring such computation) that requires an adjustment to
          the conversion Price pursuant to Section 15.5(a), (b), (c),
          (d), (e) or (f) occurs on or after the Expiration Time for
          the tender or exchange offer requiring such computation and
          prior to the day in question, the Closing Price for each
          Trading Day on and after the "ex" date for such other event
          shall be adjusted by multiplying such Closing Price by the
          reciprocal of the fraction by which the Conversion Price is
          so required to be adjusted as a result of such other event. 
          For purposes of this paragraph, the term "ex" date, (1) when
          used with respect to any issuance or distribution, means the
          first date on which the Common Stock trades regular way on
          the relevant exchange or in the relevant market from which
          the Closing Price was obtained without the right to receive
          such issuance or distribution, (2) when used with respect to
          any subdivision or combination of shares of Common Stock,
          means the first date on which the common Stock trades regular
          way on such exchange or in such market after the time at
          which such subdivision or combination becomes effective and
          (3) when used with respect to any tender or exchange offer
          means the first date on which the Common Stock trades regular
          way on such exchange or in such market after the expiration
          of such offer.  Notwithstanding the foregoing, whenever
          successive adjustments to the Conversion Price are called for
          pursuant to this Section 15.5, such adjustments shall be made
          to the Current Market Price as may be necessary or
          appropriate to effectuate the intent of this Section 15.5 and
          to avoid unjust or inequitable results as determined in good
          faith by the Board of Directors.

               (3)  "fair market value" shall mean the amount which a
          willing buyer would pay a willing seller in an arm's-length
          transaction.

               (4)  "Record Date" shall mean, with respect to any
          dividend, distribution or other transaction or event in which
          the holders of Common Stock have the right to receive any
          cash, securities or other property or in which the Common
          Stock (or other applicable security) is exchanged for or
          converted into any combination of cash, securities or other
          property, the date fixed for determination of stockholders
          entitled to receive such cash, securities or other property
          (whether such date is fixed by the Board of Directors or by
          statute, contract or otherwise).

               (5)  "Trading Day" shall mean (x) if the applicable
          security is listed or admitted for trading on the New York
          Stock Exchange or another national security exchange, a day
          on which the New York Stock Exchange or that other national
          security exchange is open for business or (y) if the
          applicable security is quoted on the Nasdaq National Market,
          a day on which trades may be made thereon or (z) if the
          applicable security is not so listed, admitted for trading or
          quoted, any day other than a Saturday or Sunday or a day on
          which banking institutions in the State of New York are
          authorized or obligated by law or executive order to close.

               (h)  The Company may make such reductions in the
     Conversion Price, in addition to those required by Sections
     15.5(a), (b), (c), (d), (e) and (f), as the Board of Directors
     considers to be advisable to avoid or diminish any income tax to
     holders of Common Stock or rights to purchase Common Stock
     resulting from any dividend or distribution of stock (or rights to
     acquire stock) or from any event treated as such for income tax
     purposes.  To the extent permitted by applicable law, the Company
     from time to time may reduce the Conversion Price by any amount
     for any period of time if the period is at least 20 days, the
     reduction is irrevocable during the period and the Board of
     Directors shall have made a determination that such reduction
     would be in the best interests of the Company, which determination
     shall be conclusive and described in a Board Resolution.  Whenever
     the Conversion Price is reduced pursuant to the preceding
     sentence, the Company shall mail to all holders of record of the
     Notes a notice of the reduction at least 15 days prior to the date
     the reduced Conversion Price takes effect, and such notice shall
     state the reduced Conversion Price and the period it will be in
     effect.

               (i)  No adjustment in the Conversion Price shall be
     required unless such adjustment would require an increase or
     decrease of at least 1% in such price; provided, however, that any
     adjustments which by reason of this Section 15.5(i) are not
     required to be made shall be carried forward and taken into
     account in any subsequent adjustment.  All calculations under this
     Article XV shall be made by the Company and shall be made to the
     nearest cent or to the nearest one-hundredth of a share, as the
     case may be.

               No adjustment need be made for rights to purchase Common
     Stock pursuant to a Company plan for reinvestment of dividends or
     interest.

               No adjustment need be made for a change in the par
     value, or to or from no par value, of the Common Stock.

               To the extent the Notes become convertible into cash,
     assets, property or securities (other than Common Stock of the
     Company), no adjustment need be made thereafter as to the cash,
     assets, property or such securities (except as such securities may
     otherwise by their terms provide), and interest shall not accrue
     on such cash.

               (j)  Whenever the Conversion Price is adjusted as herein
     provided, the Company shall promptly file with the Trustee and any
     conversion agent other than the Trustee an Officers' Certificate
     setting forth the Conversion Price after such adjustment and
     setting forth a brief statement of the facts requiring such
     adjustment.  Promptly after delivery of such certificate, the
     Company shall prepare a notice of such adjustment of the
     Conversion Price setting forth the adjusted Conversion Price and
     the date on which each adjustment becomes effective and shall mail
     such notice of such adjustment of the Conversion Price to the
     holder of each Note at his last address appearing on the Note
     register provided for in Section 2.5 of this Indenture, within 20
     days after execution thereof.  Failure to deliver such notice
     shall not effect the legality or validity of any such supplemental
     indenture.

               (k)  In any case in which this Section 15.5 provides
     that an adjustment shall become effective immediately after a
     Record Date for an event, the Company may defer until the
     occurrence of such event (i) issuing to the holder of any Note
     converted after such Record Date and before the occurrence of such
     event the additional shares of Common Stock issuable upon such
     conversion by reason of the adjustment required by such event over
     and above the Common Stock issuable upon such conversion before
     giving effect to such adjustment and (ii) paying to such holder
     any amount in cash in lieu of any fraction pursuant to Section
     15.3.

               Section 15.6  Effect of Reclassification, Consolidation,
     Merger or Sale.  If any of the following events occur, namely (i)
     any reclassification or change of outstanding shares of Common
     Stock (other than a change in par value, or to or from no par
     value, as a result of a subdivision or combination), (ii) any
     consolidation, merger or combination of the Company with another
     corporation as a result of which holders of Common Stock shall be
     entitled to receive stock, securities or other property or assets
     (including cash) with respect to or in exchange for such Common
     Stock or (iii) any sale or conveyance of the properties and assets
     of the Company as, or substantially as, an entirety to any other
     corporation as a result of which holders of Common Stock shall be
     entitled to receive stock, securities or other property or assets
     (including cash) with respect to or in exchange for such Common
     Stock, then the Company or the successor or purchasing
     corporation, as the case may be, shall execute with the Trustee a
     supplemental indenture (which shall comply with the Trust
     Indenture Act as in force at the date of execution of such
     supplemental indenture if such supplemental indenture is then
     required to so comply) providing that such Note shall be
     convertible into the kind and amount of shares of stock and other
     securities or property or assets (including cash) receivable upon
     such reclassification, change, consolidation, merger, combination,
     sale or conveyance by a holder of a number of shares of Common
     Stock issuable upon conversion of such Notes (assuming, for such
     purposes, a sufficient number of authorized shares of Common Stock
     available to convert all such Notes) immediately prior to such
     reclassification, change, consolidation, merger, combination, sale
     or conveyance, assuming such holder of Common Stock did not
     exercise his rights of election, if any, as to the kind or amount
     of securities, cash or other property receivable upon such
     reclassification, change, consolidation, merger, combination, sale
     or conveyance (provided that, if the kind or amount of securities,
     cash or other property receivable upon such reclassification,
     change, consolidation, merger, combination, sale or conveyance is
     not the same for each share of Common Stock in respect of which
     such rights of election shall not have been exercised ("non-
     electing share"), then for the purposes of this Section 15.6 the
     kind and amount of securities, cash or other property receivable
     upon such reclassification, change, consolidation, merger,
     combination, sale or conveyance for each non-electing share shall
     be deemed to be the kind and amount so receivable per share by a
     plurality of the non-electing shares).  Such supplemental
     indenture shall provide for adjustments which shall be as nearly
     equivalent as may be practicable to the adjustments provided for
     in this Article XV.

               The Company shall cause notice of the execution of such
     supplemental indenture to be mailed to each holder of Notes, at
     his address appearing on the Note register provided for in Section
     2.5 of this Indenture, within 20 days after execution thereof. 
     Failure to deliver such notice shall not affect the legality or
     validity of such supplemental indenture.

               The above provisions of this Section shall similarly
     apply to successive reclassifications, changes, consolidations,
     mergers, combinations, sales and conveyances.  

               If this Section 15.6 applies to any event or occurrence,
     Section 15.5 shall not apply.

               Section 15.7  Transfer or Similar Taxes on Shares
     Issued.  The issue of stock certificates on conversions of Notes
     shall be made without charge to the converting Noteholder for any
     transfer or similar tax in respect of the issue thereof.  The
     Company shall not, however, be required to pay any such tax which
     may be payable in respect of any transfer involved in the issue
     and delivery of stock in any name other than that of the holder of
     any Note converted, and the Company shall not be required to issue
     or deliver any such stock certificate unless and until the person
     or persons requesting the issue thereof shall have paid to the
     Company the amount of such tax or shall have established to the
     satisfaction of the Company that such tax has been paid.

               Section 15.8  Reservation of Shares; Shares to Be Fully
     Paid; Listing of Common Stock.  The Company shall provide, free
     from preemptive rights, out of its authorized but unissued shares
     or shares held in treasury, sufficient shares to provide for the
     conversion of the Notes from time to time as such Notes are
     presented for conversion.

               Before taking any action which would cause an adjustment
     reducing the Conversion Price below the then par value, if any, of
     the shares of Common Stock issuable upon conversion of the Notes,
     the Company will take all corporate action which may, in the
     opinion of its counsel, be necessary in order that the Company may
     validly and legally issue shares of such Common Stock at such
     adjusted Conversion Price.

               The Company covenants that all shares of Common Stock
     which may be issued upon conversion of Notes will, upon issue, be
     fully paid and nonassessable by the Company and free from all
     transfer or similar taxes as described in Section 15.7, liens and
     charges with respect to the issue thereof.

               The Company further covenants that, if at any time the
     Common Stock shall be listed on the New York Stock Exchange or any
     other national securities exchange, the Company will, if permitted
     by the rules of such exchange, list and keep listed, so long as
     the Common Stock shall be so listed on such exchange, all Common
     Stock issuable upon conversion of the Notes.

               Section 15.9  Responsibility of Trustee.  The Trustee
     and any other conversion agent shall not at any time be under any
     duty or responsibility to any holder of Notes to determine whether
     any facts exist which may require any adjustment of the Conversion
     Price, or with respect to the nature or extent or calculation of
     any such adjustment when made, or with respect to the method
     employed, or herein or in any supplemental indenture provided to
     be employed, in making the same.  The Trustee and any other
     conversion agent shall not be accountable with respect to the
     validity or value (or the kind or amount) of any shares of Common
     Stock, or of any securities or property, which may at any time be
     issued or delivered upon the conversion of any Note; and the
     Trustee and any other conversion agent make no representations
     with respect thereto.  Subject to the provisions of Section 8.1,
     neither the Trustee nor any conversion agent shall be responsible
     for any failure of the Company to issue, transfer or deliver any
     shares of Common Stock or stock certificates or other securities
     or property or cash upon the surrender of any debenture for the
     purpose of conversion or to comply with any of the duties,
     responsibilities or covenants of the Company contained in this
     Article XV.  Without limiting the generality of the foregoing,
     neither the Trustee nor any conversion agent shall be under any
     responsibility to determine the correctness of any provisions
     contained in any supplemental indenture entered into pursuant to
     Section 15.6 relating either to the kind or amount of shares of
     stock or securities or property (including cash) receivable by
     Noteholders upon the conversion of their Notes after any event
     referred to in such Section 15.6 or to any adjustment to be made
     with respect thereto, but, subject to the provisions of Section
     8.1, may accept as conclusive evidence of the correctness of any
     such provisions, and shall be protected in relying upon, the
     Officers' Certificate (which the Company shall be obligated to
     file with the Trustee prior to the execution of any such
     supplemental indenture) with respect thereto.

               Section 15.10  Notice to Holders Prior to Certain
     Actions.  In case:

               (a)  the Company makes any distribution or dividend that
          would require an adjustment in the Conversion Price pursuant
          to Section 15.5; or

               (b)  the Company takes any action that would require a
          supplemental indenture pursuant to Section 15.6; or

               (c)  of the voluntary or involuntary dissolution,
          liquidation or winding-up of the Company, the Company shall
          cause to be filed with the Trustee and to be mailed to each
          holder of Notes at his address appearing on the Note register
          provided for in Section 2.5 of this Indenture, as promptly as
          possible but in any event at least 15 days prior to the
          applicable date hereinafter specified, a notice stating (x)
          the date on which a record date is to be taken for the
          purpose of such dividend, distribution, rights or warrants,
          or, if a record is not to be taken, the date as of which the
          holders of Common Stock of record to be entitled to such
          dividend, distribution, rights or warrants are to be
          determined or (y) the date on which such reclassification,
          change, consolidation, merger, sale, conveyance, transfer,
          dissolution, liquidation or winding-up is expected to become
          effective or occur and the date as of which it is expected
          that holders of record of Common Stock shall be entitled to
          exchange their Common Stock for securities or other property
          deliverable upon such reclassification, change consolidation,
          merger, sale, conveyance, transfer, dissolution, liquidation
          or winding-up.  Failure to give such notice, or any defect
          therein, shall not affect the legality or validity of such
          dividend, distribution, reclassification, change,
          consolidation, merger, sale, conveyance, transfer,
          dissolution, liquidation or winding-up.  Neither the failure
          to give such notice nor any defect therein shall affect the
          legality or validity of the proceedings referenced in clauses
          (a) through (c) of this Section 15.10.

                                  ARTICLE XVI

               Section 16.8  Trust Indenture Act.  This Indenture is

     equitable right, remedy or claim under this Indenture.

               Section 16.10  Table of Contents, Headings Etc.  The
     table of contents and the titles and headings of the articles and

     hereof.

               Section 16.11  Authenticating Agent.  The Trustee may

     and delivery of Notes in connection with the original issuance
     thereof and transfers and exchanges of Notes hereunder, including
     under Sections 2.4, 2.5, 2.6, 2.7 and 3.3, as fully to all intents
     and purposes as though the authenticating agent had been expressly
     authorized by this Indenture and those Sections to authenticate
     and deliver Notes.  For all purposes of this Indenture, the
     authentication and delivery of Notes by the authenticating agent
     shall be deemed to be authentication and delivery of such Notes
     "by the Trustee" and a certificate of authentication executed on
     behalf of the Trustee by an authenticating agent shall be deemed
     to satisfy any requirement hereunder or in the Notes for the
     Trustee's certificate of authentication.  Such authenticating
     agent shall at all times be a person eligible to serve as Trustee
     hereunder pursuant to Section 8.9.

               Any corporation into which any authenticating agent may
     be merged or converted or with which it may be consolidated, or
     any corporation resulting from any merger, consolidation or
     conversion to which any authenticating agent shall be a party, or
     any corporation succeeding to the corporate trust business of any
     authenticating agent, shall be the successor of the authenticating
     agent hereunder, if such Successor Company is otherwise eligible
     under this Section, without the execution or filing of any paper
     or any further act on the part of the parties hereto or the
     authenticating agent or such Successor Company.

               Any authenticating agent may at any time resign by
     giving written notice of resignation to the Trustee and to the
     Company.  The Trustee may at any time terminate the agency of any
     authenticating agent by giving written notice of termination to
     such authenticating agent and to the Company.  Upon receiving such
     a notice of resignation or upon such a termination, or in case at
     any time any authenticating agent shall cease to be eligible under
     this Section, the Trustee shall promptly appoint a successor
     authenticating agent (which may be the Trustee), shall give
     written notice of such appointment to the Company and shall mail
     notice of such appointment to all holders of Notes as the names
     and addresses of such holders appear on the Note register.

               The Trustee agrees to pay to the authenticating agent
     from time to time reasonable compensation for its services, and
     the Trustee shall be entitled to be reimbursed for such payments,
     subject to Section 8.6.

               The provisions of Sections 8.2, 8.3, 8.4, 9.3 and this
     Section 16.11 shall be applicable to any authenticating agent.

               Section 16.12  Execution in Counterparts.  This
     Indenture may be executed in any number of counterparts, each of
     which shall be an original, but such counterparts shall together
     constitute but one and the same instrument.

               Section 16.13  Pooling of Interests.  The Company
     desires to preserve its ability to account for acquisition and
     other business combination transactions using the pooling of
     interests method where appropriate, and the provisions of this
     Indenture shall be interpreted accordingly.

                                ARTICLE XVII

                              EXCHANGE OF NOTES

               Section 17.1  Right to Exchange.  Subject to and upon
     compliance with the provisions of this Indenture, the holder of
     any Note shall have the right, at his option, at any time prior to
     the close of business on November 1, 2000 (except that, with
     respect to any Note or portion of a Note which shall be called for
     redemption or delivered for repurchase, such right shall
     terminate, except as provided in the fourth paragraph of Section
     17.2, at the close of business on the last Trading Day prior to
     the date fixed for redemption of such Note or portion of a Note
     unless the Company shall default in payment due upon redemption
     thereof) to exchange the principal amount of any such Note, or any
     portion of such principal amount which is $1,000 or an integral
     multiple thereof, into that number of fully paid and nonassessable
     shares of Preferred Stock (as such shares shall then be
     constituted) obtained by dividing the principal amount of the Note
     or portion thereof surrendered for exchange by the Exchange Price
     in effect at such time, by surrender of the Note so to be
     converted in whole or in part in the manner provided in Section
     17.2.  A holder of Notes is not entitled to any rights of a holder
     of Preferred Stock until such holder has converted his Notes to
     Preferred Stock, and only to the extent such Notes are deemed to
     have been exchanged for Preferred Stock under this Article XVII.

               Section 17.2  Exercise of Exchange Privilege; Issuance
     of Preferred Stock on Exchange; Adjustment for Interest or
     Dividends.  In order to exercise the exchange privilege with
     respect to any Note in definitive form, the holder of any such
     Note to be converted in whole or in part shall surrender such
     Note, duly endorsed, at an office or agency maintained by the
     Company pursuant to Section 5.2, accompanied by the funds, if any,
     required by the penultimate paragraph of this Section 17.2, and
     shall give written notice of exchange in the form provided on the
     Notes (or such other notice which is acceptable to the Company) to
     the office or agency that the holder elects to exchange such Note
     or the portion thereof specified in said notice.  Such notice
     shall also state the name or names (with address) in which the
     certificate or certificates for shares of Preferred Stock which
     shall be issuable on such conversion shall be issued and shall be
     accompanied by transfer taxes, if required pursuant to Section
     17.7.  Each such Note surrendered for exchange shall, unless the
     shares issuable on exchange are to be issued in the same name as
     the registration of such Note, be duly endorsed by, or be
     accompanied by instruments of transfer in form satisfactory to the
     Company duly executed by, the holder or his duly authorized
     attorney.

               In order to exercise the exchange privilege with respect
     to any interest in a Note in global form, the beneficial holder
     must complete the appropriate instruction form for exchange
     pursuant to the Depositary's book-entry exchange program and
     follow the other procedures set forth in such program.

               As promptly as practicable after satisfaction of the
     requirements for exchange set forth above, subject to compliance
     with any restrictions on transfer if shares issuable on exchange
     are to be issued in a name other than that of the Noteholder (as
     if such transfer were a transfer of the Note or Notes (or portion
     thereof) so exchanged), the Company shall issue and shall deliver
     to such holder at the office or agency maintained by the Company
     for such purpose pursuant to Section 5.2, a certificate or
     certificates for the number of full shares issuable upon the
     exchange of such Note or portion thereof in accordance with the
     provisions of this Article XVII.  In case any Note of a
     denomination greater than $1,000 shall be surrendered for partial
     exchange, and subject to Section 2.3, the Company shall execute
     and the Trustee shall authenticate and deliver to the holder of
     the Note so surrendered, without charge to him, a new Note or
     Notes in authorized denominations in an aggregate principal amount
     equal to the exchanged portion of the surrendered Note.

               Each exchange shall be deemed to have been effected as
     to any such Note (or portion thereof) on the date on which the
     requirements set forth above in this Section 17.2 have been
     satisfied as to such Note (or portion thereof), and the person in
     whose name any certificate or certificates for shares of Preferred
     Stock shall be issuable upon such exchange shall be deemed to have
     become on said date the holder of record of the shares represented
     thereby; provided, however, that any such surrender on any date
     when the stock transfer books of the Company shall be closed shall
     constitute the person in whose name the certificates are to be
     issued as the record holder thereof for all purposes on the next
     succeeding day on which such stock transfer books are open, but
     such exchange shall be at the Exchange Price in effect on the date
     upon which such Note shall have been surrendered.

               Any Note or portion thereof surrendered for exchange
     during the period from the close of business on the record date
     for any interest payment date through the close of business on the
     Trading Day next preceding such interest payment date shall
     (unless such Note or portion thereof being converted shall have
     been called for redemption on a date in such period) be
     accompanied by payment, in funds acceptable to the Company, of an
     amount equal to the interest otherwise payable on such interest
     payment date on the principal amount being converted; provided,
     however, that no such payment need be made if there shall exist at
     the time of exchange a default in the payment of interest on the
     Notes.  An amount equal to such payment shall be paid by the
     Company on such interest payment date to the holder of such Note
     at the close of business on such record date; provided, however,
     that if the Company shall default in the payment of interest on
     such interest payment date, such amount shall be paid to the
     person who made such required payment.  In the case of any
     exchange, dividends on the Preferred Stock issuable upon such
     exchange will commence to accrue as of the most recent date as of
     which interest has been paid, or duly provided for, on the Notes
     unless no interest has been paid or duly provided for on the
     Notes, in which case from December 22, 1995.  Except as provided
     above in this Section 17.2, no adjustment shall be made for
     interest accrued on any Note converted or for dividends on any
     shares issued upon the exchange of such Note as provided in this
     Article.

               Upon the exchange of an interest in a Note in global
     form, the Trustee, or the Custodian at the direction of the
     Trustee, shall make an adjustment on its records with respect to
     such Note in global form as to the reduction in the principal
     amount represented thereby.

               Section 17.3  Cash Payments in Lieu of Fractional
     Shares.  No fractional shares of Preferred Stock or scrip
     representing fractional shares shall be issued upon exchange of
     Notes.  If more than one Note shall be surrendered for exchange at
     one time by the same holder, the number of full shares which shall
     be issuable upon exchange shall be computed on the basis of the
     aggregate principal amount of the Notes (or specified portions
     thereof to the extent permitted hereby) so surrendered.  If any
     fractional share of stock would be issuable upon the exchange of
     any Note or Notes, the Company shall make an adjustment therefor
     in cash at the current market value thereof.  The Current Market
     Value of a share of Preferred Stock shall be the greater of (i)
     the Liquidation Preference thereof or (ii) the current market
     value of that number of shares of Common Stock (including any
     fraction of a share) into which one share of Preferred Stock may
     then be converted.  The current market value of a share of Common
     Stock shall be the Closing Price on the first Trading Day
     immediately preceding the day on which the Notes (or specified
     portions thereof) are deemed to have been converted and such
     Closing Price shall be determined as provided in Section 15.5(g).

               Section 17.4  Exchange Price.  The exchange price shall
     be $1000.00 (herein called the "Exchange Price").

               Section 17.5  Adjustment of Exchange Price.  The
     Exchange Price shall be adjusted from time to time by the Company
     as follows:

               (a)  In the event that the provisions of the Series C
     Preferred Stock as set forth in the Certificate of Designation
     attached as Exhibit C hereto shall at any time be amended in
     accordance with the provisions of the Certificate of Designation
     and this Indenture, to reduce the Liquidation Preference of, or
     the amount of dividends or other distributions payable with
     respect to, the Series C Preferred Stock, or to change the
     Conversion Price at which such Series C Preferred Stock is
     convertible into Common Stock pursuant to the provisions of the
     Certificate of Designation (or the manner in which such Conversion
     Price is adjusted as set forth in Section 8 thereof), the Exchange
     Price shall be adjusted in such manner as the Board of Directors
     of the Company shall determine is fair and equitable, which
     determination shall be conclusive and shall be set forth in a
     Board Resolution.

               (b)  The Company may make such reductions in the
     Exchange Price, in addition to those required by Section 17.5(a),
     as the Board of Directors considers to be advisable to avoid or
     diminish any income tax to holders of Preferred Stock or rights to
     purchase Preferred Stock resulting from any dividend or
     distribution of stock (or rights to acquire stock) or from any
     event treated as such for income tax purposes.  To the extent
     permitted by applicable law, the Company from time to time may
     reduce the Exchange Price by any amount for any period of time if
     the period is at least 20 days, the reduction is irrevocable
     during the period and the Board of Directors shall have made a
     determination that such reduction would be in the best interests
     of the Company, which determination shall be conclusive and
     described in a Board Resolution.  Whenever the Exchange Price is
     reduced pursuant to the preceding sentence, the Company shall mail
     to all holders of record of the Notes a notice of the reduction at
     least 15 days prior to the date the reduced Exchange Price takes
     effect, and such notice shall state the reduced conversion Price
     and the period it will be in effect.

               (c)  No adjustment in the Exchange Price shall be
     required unless such adjustment would require an increase or
     decrease of at least 1% in such price; provided, however, that any
     adjustments which by reason of this Section 17.5(c) are not
     required to be made shall be carried forward and taken into
     account in any subsequent adjustment.  All calculations under this
     Article XVII shall be made by the Company and shall be made to the
     nearest cent or to the nearest one-hundredth of a share, as the
     case may be.

               No adjustment need be made for a change in the par
     value, or to or from no par value, of the Preferred Stock.

               To the extent the Notes become convertible into cash,
     assets, property or securities (other than Preferred Stock or
     Common Stock of the Company), no adjustment need be made
     thereafter as to the cash, assets, property or such securities
     (except as such securities may otherwise by their terms provide),
     and interest shall not accrue on such cash.

               (d)  Whenever the Exchange Price is adjusted as herein
     provided, the Company shall promptly file with the Trustee and any
     exchange agent other than the Trustee an Officers' Certificate
     setting forth the Exchange Price after such adjustment and setting
     forth a brief statement of the facts requiring such adjustment. 
     Promptly after delivery of such certificate, the Company shall
     prepare a notice of such adjustment of the Exchange Price setting
     forth the adjusted Exchange Price and the date on which each
     adjustment becomes effective and shall mail such notice of such
     adjustment of the Exchange Price to the holder of each Note at his
     last address appearing on the Note register provided for in
     Section 2.5 of this Indenture, within 20 days after execution
     thereof.  Failure to deliver such notice shall not effect the
     legality or validity of any such supplemental indenture.

               (e)  In any case in which this Section 17.5 provides
     that an adjustment shall become effective immediately after a
     Record Date for an event, the Company may defer until the
     occurrence of such event (i) issuing to the holder of any Note
     converted after such Record Date and before the occurrence of such
     event the additional shares of Preferred Stock issuable upon such
     conversion by reason of the adjustment required by such event over
     and above the Preferred Stock issuable upon such conversion before
     giving effect to such adjustment and (ii) paying to such holder
     any amount in cash in lieu of any fraction pursuant to Section
     17.3.

               Section 17.6  Effect of Reclassification, Consolidation,
     Merger or Sale.  If any of the following events occur, namely (i)
     any reclassification or change of outstanding shares of Preferred
     Stock (other than a change in par value, or to or from no par
     value, as a result of a subdivision or combination), (ii) any
     consolidation, merger or combination of the Company with another
     corporation as a result of which holders of Preferred Stock shall
     be entitled to receive stock, securities or other property or
     assets (including cash) with respect to or in exchange for such
     Preferred Stock or (iii) any sale or conveyance of the properties
     and assets of the Company as, or substantially as, an entirety to
     any other corporation as a result of which holders of Preferred
     Stock shall be entitled to receive stock, securities or other
     property or assets (including cash) with respect to or in exchange
     for such Preferred Stock, then the Company or the successor or
     purchasing corporation, as the case may be, shall execute with the
     Trustee a supplemental indenture (which shall comply with the
     Trust Indenture Act as in force at the date of execution of such
     supplemental indenture if such supplemental indenture is then
     required to so comply) providing that such Note shall be
     exchangeable into the kind and amount of shares of stock and other
     securities or property or assets (including cash) receivable upon
     such reclassification, change, consolidation, merger, combination,
     sale or conveyance by a holder of a number of shares of Preferred
     Stock issuable upon exchange of such Notes (assuming, for such
     purposes, a sufficient number of authorized shares of Preferred
     Stock available to exchange all such Notes) immediately prior to
     such reclassification, change, consolidation, merger, combination,
     sale or conveyance, assuming such holder of Preferred Stock did
     not exercise his rights of election, if any, as to the kind or
     amount of securities, cash or other property receivable upon such
     reclassification, change, consolidation, merger, combination, sale
     or conveyance (provided that, if the kind or amount of securities,
     cash or other property receivable upon such reclassification,
     change, consolidation, merger, combination, sale or conveyance is
     not the same for each share of Preferred Stock in respect of which
     such rights of election shall not have been exercised ("non-
     electing share"), then for the purposes of this Section 17.6 the
     kind and amount of securities, cash or other property receivable
     upon such reclassification, change, consolidation, merger,
     combination, sale or conveyance for each non-electing share shall
     be deemed to be the kind and amount so receivable per share by a
     plurality of the non-electing shares).  Such supplemental
     indenture shall provide for adjustments which shall be as nearly
     equivalent as may be practicable to the adjustments provided for
     in this Article XVII.

               The Company shall cause notice of the execution of such
     supplemental indenture to be mailed to each holder of Notes, at
     his address appearing on the Note register provided for in Section
     2.5 of this Indenture, within 20 days after execution thereof. 
     Failure to deliver such notice shall not affect the legality or
     validity of such supplemental indenture.

               The above provisions of this Section shall similarly
     apply to successive reclassifications, changes, consolidations,
     mergers, combinations, sales and conveyances.  

               Section 17.7  Transfer or Similar Taxes on Shares
     Issued.  The issue of stock certificates on exchanges of Notes
     shall be made without charge to the exchanging Noteholder for any
     transfer or similar tax in respect of the issue thereof.  The
     Company shall not, however, be required to pay any such tax which
     may be payable in respect of any transfer involved in the issue
     and delivery of stock in any name other than that of the holder of
     any Note converted, and the Company shall not be required to issue
     or deliver any such stock certificate unless and until the person
     or persons requesting the issue thereof shall have paid to the
     Company the amount of such tax or shall have established to the
     satisfaction of the Company that such tax has been paid.

               Section 17.8  Reservation of Stock; Shares to Be Fully
     Paid; Listing of Preferred Stock.  The Company shall provide, free
     from preemptive rights, out of its authorized but unissued shares
     or shares held in treasury, sufficient shares to provide for the
     exchange of the Notes from time to time as such Notes are
     presented for exchange. 

               Before taking any action which would cause an adjustment
     reducing the Exchange Price below the then par value, if any, of
     the shares of Preferred Stock issuable upon exchange of the Notes,
     the Company will take all corporate action which may, in the
     opinion of its counsel, be necessary in order that the Company may
     validly and legally issue shares of such Preferred Stock at such
     adjusted Exchange Price.

               The Company covenants that all shares of Preferred Stock
     which may be issued upon exchange of Notes will, upon issue, be
     fully paid and nonassessable by the Company and free from all
     transfer or similar taxes as described in Section 17.7, liens and
     charges with respect to the issue thereof.

               The Company further covenants that, if at any time the
     Preferred Stock shall be listed on the New York Stock Exchange or
     any other national securities exchange, the Company will, if
     permitted by the rules of such exchange, list and keep listed, so
     long as the Preferred Stock shall be so listed on such exchange,
     all Preferred Stock issuable upon exchange of the Notes.

               Section 17.9  Responsibility of Trustee.  The Trustee
     and any other exchange agent shall not at any time be under any
     duty or responsibility to any holder of Notes to determine whether
     any facts exist which may require any adjustment of the Exchange
     Price, or with respect to the nature or extent or calculation of
     any such adjustment when made, or with respect to the method
     employed, or herein or in any supplemental indenture provided to
     be employed, in making the same.  The Trustee and any other
     conversion agent shall not be accountable with respect to the
     validity or value (or the kind or amount) of any shares of
     Preferred Stock, or of any securities or property, which may at
     any time be issued or delivered upon the exchange of any Note; and
     the Trustee and any other exchange agent make no representations
     with respect thereto.  Subject to the provisions of Section 8.1,
     neither the Trustee nor any exchange agent shall be responsible
     for any failure of the Company to issue, transfer or deliver any
     shares of Preferred Stock or stock certificates or other
     securities or property or cash upon the surrender of any debenture
     for the purpose of exchange or to comply with any of the duties,
     responsibilities or covenants of the Company contained in this
     Article XVII, without limiting the generality of the foregoing,
     neither the Trustee nor any exchange agent shall be under any
     responsibility to determine the correctness of any provisions
     contained in any supplemental indenture entered into pursuant to
     Section 17.6 relating either to the kind or amount of shares of
     stock or securities or property (including cash) receivable by
     Noteholders upon the exchange of their Notes after any event
     referred to in such Section 17.6 or to any adjustment to be made
     with respect thereto, but, subject to the provisions of Section
     8.1, may accept as conclusive evidence of the correctness of any
     such provisions, and shall be protected in relying upon, the
     Officers' Certificate (which the Company shall be obligated to
     file with the Trustee prior to the execution of any such
     supplemental indenture) with respect thereto.

               Section 17.10  Notice to Holders Prior to Certain
     Actions.  In case:

               (a)  the Company takes any action that would require a
     supplemental indenture pursuant to Section 17.6; or

               (b)  of the voluntary or involuntary dissolution,
     liquidation or winding-up of the Company, the Company shall cause
     to be filed with the Trustee and to be mailed to each holder of
     Notes at his address appearing on the Note register provided for
     in Section 2.5 of this Indenture, as promptly as possible but in
     any event at least 15 days prior to the applicable date
     hereinafter specified, a notice stating (x) the date on which a
     record date is to be taken for the purpose of such dividend,
     distribution, rights or warrants, or, if a record is not to be
     taken, the date as of which the holders of Preferred Stock of
     record to be entitled to such dividend, distribution, rights or
     warrants are to be determined or (y) the date on which such
     reclassification, change, consolidation, merger, sale, conveyance,
     transfer, dissolution, liquidation or winding-up is expected to
     become effective or occur and the date as of which it is expected
     that holders of record of Preferred Stock shall be entitled to
     exchange their Preferred Stock for securities or other property
     deliverable upon such reclassification, change consolidation,
     merger, sale, conveyance, transfer, dissolution, liquidation or
     winding-up.  Failure to give such notice, or any defect therein,
     shall not affect the legality or validity of such dividend,
     distribution, reclassification, change, consolidation, merger,
     sale, conveyance, transfer, dissolution, liquidation or winding-
     up.  Neither the failure to give such notice nor any defect
     therein shall affect the legality or validity of the proceedings
     referenced in clauses (a) through (b) of this Section 17.10.

               State Street Bank and Trust Company hereby accepts the
     trusts in this Indenture declared and provided, upon the terms and
     conditions hereinabove set forth.

          IN WITNESS WHEREOF, the parties hereto have caused this
     Indenture to be duly signed, and their respective corporate seals
     to be hereunto affixed and attested, all as of the date first
     written above.

     5 1/2% Senior Convertible/Exchangeable Note Due 2000

               This Note is one of a duly authorized issue of Notes in
     the Company, designated as its 5 1/2% Senior Convertible/Ex-
     changeable Notes due 2000 (herein called the "Notes"), limited to
     the aggregate principal amount of $150,000,000 all issued or to be
     issued under and pursuant to an indenture dated as of
     _____________ (herein called the "Indenture"), between the Company
     and State Street Bank and Trust Company (herein called the
     "Trustee"), to which Indenture and all indentures supplemental
     thereto reference is hereby made for a description of the rights,
     limitations of rights, obligations, duties and immunities
     thereunder of the Trustee, the Company and the holders of the
     Notes.

               In case an Event of Default, as defined in the
     Indenture, shall have occurred and be continuing, the principal of
     and accrued interest on all Notes may be declared, and upon said
     declaration shall become, due and payable, in the manner, with the
     effect and subject to the conditions provided in the Indenture.

               The Indenture contains provisions permitting the Company
     and the Trustee, with the consent of the holders of not less than
     a majority in aggregate principal amount of the Notes at the time
     outstanding, evidenced as in the Indenture provided to execute
     supplemental indentures adding any provisions to or changing in
     any manner or eliminating any of the provisions of the Indenture
     or of any supplemental indenture or modifying in any manner the
     rights of the holders of the Notes; provided, however, that no
     such supplemental indenture shall (i) extend the fixed maturity of
     any Note, or reduce the rate or extend the time of payment of
     interest thereon, or reduce the principal amount thereof or
     premium, if any, thereon, or reduce any amount payable on
     redemption thereof, alter the obligation of the Company to redeem
     the Notes at the option of the holders upon the occurrence of a
     Change of Control or impair or affect the right of any Noteholder
     to institute suit for the payment thereof, or make the principal
     thereof or interest or premium, if any, thereon payable in any
     coin or currency other than that provided in the Notes or impair
     the right to exchange the Notes for Preferred Stock or to convert
     the Notes into Common Stock subject to the terms set forth in the
     Indenture, including Sections 15.6 and 17.6 thereof, without the
     consent of the holder of each Note so affected or (ii) reduce the
     aforesaid percentage of Notes, the holders of which are required
     to consent to any such supplemental indenture, without the consent
     of the holders of all Notes then outstanding.  It is also provided
     in the Indenture that, prior to any declaration accelerating the
     maturity of the Notes, the holders of a majority in aggregate
     principal amount of the Notes at the time outstanding may on
     behalf of the holders of all of the Notes waive any past default
     or Event of Default under the Indenture and its consequences
     except a default in the payment of interest or any premium on or
     the principal of any of the Notes, a failure by the Company to
     convert any Notes into Common Stock of the Company or to exchange
     any Notes for Preferred Stock of the Company or a default in
     respect of a covenant or provision of the Indenture which under
     Article XI thereof cannot be modified or amended without the
     consent of the holders of all Notes then outstanding.  Any such
     consent or waiver by the holder of this Note (unless revoked as
     provided in the Indenture) shall be conclusive and binding upon
     such holder and upon all future holders and owners of this Note
     and any Notes which may be issued in exchange or substitution
     hereof, irrespective of whether or not any notation thereof is
     made upon this Note or such other Notes.

               No reference herein to the Indenture and no provision of
     this Note or of the Indenture shall alter or impair the obligation
     of the Company, which is absolute and unconditional, to pay the
     principal of and any premium and interest on this Note at the
     place, at the respective times, at the rate and in the coin or
     currency herein prescribed.

               Interest on the Notes shall be computed on the basis of
     a year of twelve 30-day months.

               The Notes are issuable in registered form without
     coupons in denominations of $1,000 principal amount and integral
     multiples thereof.  At the office or agency of the Company
     referred to on the face hereof, and in the manner and subject to
     the limitations provided in the Indenture, without payment of any
     service charge but with payment of a sum sufficient to cover any
     tax or other governmental charge that may be imposed in connection
     with any registration or exchange of Notes, Notes may be exchanged
     for a like aggregate principal amount of Notes of other authorized
     denominations.

               The Notes will not be redeemable at the option of the
     Company prior to November 2, 1998.  On or after such date and
     prior to maturity the Notes may be redeemed at the option of the
     Company as a whole, or from time to time in part, upon mailing a
     notice of such redemption not less than 30 nor more than 60 days
     before the date fixed for redemption to the holders of Notes at
     their last registered addresses, all as provided in the Indenture,
     at the following optional redemption prices (expressed as
     percentages of the principal amount), together in each case with
     accrued interest to the date fixed for redemption.

     If redeemed during the 12-month period beginning:

               Date                             Percentage
          November 2, 1998                        102.2%
          November 1, 1999                        101.1% 

     and 100% at November 1, 2000; provided that if the date fixed for
     redemption is a May 1 or November 1, then the interest payable on
     such date shall be paid to the holder of record on the next
     preceding April 15 or October 15, respectively.

               If a Change of Control (as defined in the Indenture)
     shall occur at any time, then each holder of Notes shall have the
     right to require that the Company purchase such holder's Notes in
     whole or in part in integral multiples of $1,000, at a purchase
     price in cash in an amount equal to 101% of the principal amount
     of such Notes, plus accrued and unpaid interest, if any, on the
     repurchase date pursuant to an offer to be made by the Company and
     in accordance with the procedures set forth in the Indenture.

               Subject to the provisions of the Indenture, the holder
     hereof has the right, at its option, at any time after 60 days
     following the latest date of original issuance of the Notes and
     prior to the close of business on November 1, 2000, or, as to all
     or any portion hereof called for redemption, prior to the close of
     business on the Business Day next preceding the date fixed for
     redemption (unless the Company shall default in payment due upon
     redemption thereof), to exchange the principal amount hereof or
     any portion of such principal which is $1,000 or an integral
     multiple thereof, into that number of fully paid and non-
     assessable shares of the Company's Preferred Stock obtained by
     dividing the principal amount of this Note, or portion thereof to
     be exchanged by the exchange price of $1000.00, or such exchange
     price as adjusted from time to time as provided in the Indenture,
     or to convert the principal hereof or any portion of such
     principal which is $1,000 or an integral multiple thereof, into
     that number of fully paid and non-assessable shares of Company's
     Common Stock, as said shares shall be constituted at the date of
     conversion, obtained by dividing the principal amount of this Note
     or portion thereof to be converted by the conversion price of
     $53.00 or such conversion price as adjusted from time to time as
     provided in the Indenture, in either case, upon surrender of this
     Note, together with any conversion or exchange notice, as the case
     may be, as provided in the Indenture, to the Company at the office
     or agency of the Company maintained for that purpose in the
     Borough of Manhattan, The City of New York, or at the option of
     such holder, the Corporate Trust Office of the Trustee, and,
     unless the shares issuable on conversion or exchange are to be
     issued in the same name as this Note, duly endorsed by, or
     accompanied by instruments of transfer in form satisfactory to the
     Company duly executed by, the holder or by his duly authorized
     attorney.  In the case of any exchange, dividends on the Preferred
     Stock issuable upon such exchange will commence to accrue as of
     the most recent date as of which interest has been paid, or duly
     provided for, on the Notes unless no interest has been paid or
     duly provided for on the Notes, in which case from ____________,
     1995 and no further adjustment will be made with regard to
     interest due on the Note, or portions thereof, so exchanged.  No
     adjustment in respect of interest or dividends will be made upon
     any conversion; provided, however, that if this Note shall be
     surrendered for conversion or exchange during the period from the
     close of business on any record date for the payment of interest
     through the close of business on the Business Day next preceding
     the following interest payment date, this Note (unless it or the
     portion being converted or exchanged shall have been called for
     redemption on a date in such period) must be accompanied by an
     amount, in funds acceptable to the Company, equal to the interest
     payable on such interest payment date on the principal amount
     being converted or exchanged.  No fractional shares will be issued
     upon any conversion or exchange, but an adjustment in cash will be
     made, as provided in the Indenture, in respect of any fraction of
     a share which would otherwise be issuable upon the surrender of
     any Note or Notes for conversion or exchange.

               Any Notes called for redemption, unless surrendered for
     exchange or conversion on or before the close of business on the
     date fixed for redemption, may be deemed to be purchased from the
     holder of such Notes in an amount equal to the applicable
     redemption price, together with accrued interest to the date fixed
     for redemption, by one or more investment bankers or other
     purchasers who may agree with the Company to purchase such Notes
     from the holders thereof and convert them into Common Stock or
     exchange them for Preferred Stock of the Company and to make
     payment for such Notes as aforesaid to the Trustee in trust for
     such holders.

               Upon due presentment for registration of transfer of
     this Note at the office or agency of the Company in the Borough of
     Manhattan, The City of New York, or at the option of the holder of
     this Note, at the Corporate Trust office of the Trustee, a new
     Note or Notes of authorized denominations for an equal aggregate
     principal amount will be issued to the transferee in exchange
     thereof, subject to the limitations provided in the Indenture,
     without charge except for any tax or other governmental charge
     imposed in connection therewith.

               The Company, the Trustee, any authenticating agent, any
     paying agent, exchange or any conversion agent and any Note
     registrar may deem and treat the registered holder hereof as the
     absolute owner of this Note (whether or not this Note shall be
     overdue and notwithstanding any notation of ownership or other
     writing hereon made by anyone other than the Company or any Note
     registrar), for the purpose of receiving payment hereof, or on
     account hereof, for the exchange or conversion hereof and for all
     other purposes, and neither the Company nor the Trustee nor any
     other authenticating agent nor any paying agent nor any other
     exchange or conversion agent nor any Note registrar shall be
     affected by any notice to the contrary.  All payments made to or
     upon the order of such registered holder shall, to the extent of
     the sum or sums paid, satisfy and discharge liability for monies
     payable on this Note.

               No recourse for the payment of the principal of or any
     premium or interest on this Note, or for any claim based hereon or
     otherwise in respect hereof, and no recourse under or upon any
     obligation, covenant or agreement of the Company in the Indenture
     or any indenture supplemental thereto or in any Note, or because
     of the creation of any indebtedness represented thereby, shall be
     had against any incorporator, stockholder, officer or director, as
     such, past, present or future, of the Company or of any Successor
     Company, either directly or through the Company or any Successor
     Company, whether by virtue of any constitution, statute or rule of
     law or by the enforcement of any assessment or penalty or
     otherwise, all such liability being, by the acceptance hereof and
     as part of the consideration for the issue hereof, expressly
     waived and released.

               Terms used in this Note and defined in the Indenture are
     used herein as therein defined.

     SoftKey International Inc.

     5 1/2% Senior Convertible/Exchangeable Note Due 2000

          This Note is one of a duly authorized issue of Notes of the
     Company, designated as its 5 1/2% Senior Convertible/Exchangeable
     Notes due 2000 (herein called the "Notes"), limited to the
     aggregate principal amount of $150,000,000 all issued or to be
     issued under and pursuant to an Indenture dated as of __________,
     1995 (herein called the "Indenture"), between the Company and
     State Street Bank and Trust Company (herein called the "Trustee"),
     to which Indenture and all indentures supplemental thereto
     reference is hereby made for a description of the rights,
     limitations to rights, obligations, duties and immunities
     thereunder of the Trustee, the Company and the holders of the
     Notes.

          In case an Event of Default, as defined in the Indenture,
     shall have occurred and be continuing, the principal of and
     accrued interest on all Notes may be declared, and upon said
     declaration shall become, due and payable, in the manner, with the
     effect and subject to the conditions provided in the Indenture.

          The Indenture contains provisions permitting the Company and
     the Trustee, with the consent of the holders of not less than a
     majority in aggregate principal amount of the Notes at the time
     outstanding, evidenced as in the Indenture provided, to execute
     supplemental indentures adding any provisions to or changing in
     any manner or eliminating any of the provisions of the Indenture
     or of any supplemental indenture or modifying in any manner the
     rights of the holders of the Notes; provided, however, that no
     such supplemental indenture shall (i) extend the fixed maturity of
     any Note, or reduce the rate or extend the time of payment of
     interest thereon, or reduce the principal amount thereof or
     premium, if any, thereon, or reduce any amount payable on
     redemption thereof, alter the obligation of the Company to redeem
     the Notes at the option of the holders upon the occurrence of a
     Change of Control or impair or affect the right of any Noteholder
     to institute suit for the payment thereof, or make the principal
     thereof or interest or premium, if any, thereon payable in any
     coin or currency other than that provided in the Notes or impair
     the right to exchange the Notes for Preferred Stock or to convert
     the Notes into Common Stock subject to the terms set forth in the
     Indenture, including Sections 15.6 and 17.6 thereof, without the
     consent of the holder of each Note so affected or (ii) reduce the
     aforesaid percentage of Notes, the holders of which are required
     to consent to any such supplemental indenture, without the consent
     of the holders of all Notes then outstanding.  It is also provided
     in the Indenture that, prior to any declaration accelerating the
     maturity of the Notes, the holders of a majority in aggregate
     principal amount of the Notes at the time outstanding may on
     behalf of the holders of all of the Notes waive any past default
     or Event of Default under the Indenture and its consequences
     except a default in the payment of interest or any premium on or
     the principal of any of the Notes, a failure by the Company to
     exchange the Notes for Preferred Stock or to convert any Notes
     into Common Stock of the Company or a default in respect of a
     covenant or provision of the Indenture which under Article XI
     thereof cannot be modified or amended without the consent of the
     holders of all Notes then outstanding.  Any such consent or waiver
     by the holder of this Note (unless revoked as provided in the
     Indenture) shall be conclusive and binding upon such holder and
     upon all future holders and owners of this Note and any Notes
     which may be issued in exchange or substitution hereof,
     irrespective of whether or not any notation thereof is made upon
     this Note or such other Notes.

          No reference herein to the Indenture and no provision of this
     Note or of the Indenture shall alter or impair the obligation of
     the Company, which is absolute and unconditional, to pay the
     principal of and any premium and interest on this Note at the
     place, at the respective times, at the rate and in the coin or
     currency herein prescribed.

          Interest on the Notes shall be computed on the basis of a
     year of twelve 30-day months.

          The Notes are issuable in registered form without coupons in
     denominations of $1,000 principal amount and integral multiples
     thereof.  At the office or agency of the Company referred to on
     the face hereof, and in the manner and subject to the limitations
     provided in the Indenture, without payment of any service charge
     but with payment of a sum sufficient to cover any tax or other
     governmental charge that may be imposed in connection with any
     registration or exchange of Notes, Notes may be exchanged for a
     like aggregate principal amount of Notes of other authorized
     denominations.

          The Notes will not be redeemable at the option of the Company
     prior to November 2, 1998.  On or after such date and prior to
     maturity the Notes may be redeemed at the option of the Company as
     a whole, or from time to time in part, upon mailing a notice of
     such redemption not less than 30 nor more than 60 days before the
     date fixed for redemption to the holders of Notes at their last
     registered addresses, all as provided in the Indenture, at the
     following optional redemption prices (expressed as percentages of
     the principal amount), together in each case with accrued interest
     to the date fixed for redemption.

     If redeemed during the 12-month period beginning:

               Date                          Percentage

               November 2, 1998                102.2%
               November 1, 1999                101.1%

     and 100% at November 1, 2000; provided that if the date fixed for
     redemption is a May 1 or November 1, then the interest payable on
     such date shall be paid to the holder of record on the next
     preceding April 15 or October 15, respectively.

               If a Change of Control (as defined in the Indenture)
     shall occur at any time, then each holder of Notes shall have the
     right to require that the Company purchase such holder's Notes in
     whole or in part in integral multiples of $1,000, at a purchase
     price in cash in an amount equal to 101% of the principal amount
     of such Notes, plus accrued and unpaid interest, if any, to the
     repurchase date pursuant to an offer to be made by the Company and
     in accordance with the procedures set forth in the Indenture.

               Subject to the provisions of the Indenture, the holder
     hereof has the right, at its option, at any time after 60 days
     following the latest date of original issuance of the Notes and
     prior to the close of business on November 1, 2000, or, as to all
     or any portion hereof called for redemption, prior to the close of
     business on the Business Day next preceding the date fixed for
     redemption (unless the Company shall default in payment due upon
     redemption thereof), exchange the principal amount hereof or any
     portion of such principal which is $1,000 or an integral multiple
     thereof, into that number of fully paid and non-assessable shares
     of the Company's Preferred Stock obtained by dividing the
     principal amount of this Note, or portion thereof to be exchanged,
     by the exchange price of $1000.00 or such exchange price as
     adjusted from time to time as provided in the Indenture, or to
     convert the principal hereof or any portion of such principal
     which is $1,000 or an integral multiple thereof, into that number
     of fully paid and non-assessable shares of Company's Common Stock,
     as said shares shall be constituted at the date of conversion,
     obtained by dividing the principal amount of this Note or portion
     thereof to be converted by the conversion price of $53.00 or such
     conversion price as adjusted from time to time as provided in the
     Indenture, in either case, upon surrender of this Note, together
     with an exchange notice or a conversion notice, as the case may
     be, as provided in the Indenture, to the Company at the office or
     agency of the Company maintained for that purpose in the Borough
     of Manhattan, The City of New York, or at the option of such
     holder, the Corporate Trust Office of the Trustee, and, unless the
     shares issuable on conversion or exchange are to be issued in the
     same name as this Note, duly endorsed by, or accompanied by
     instruments of transfer in form satisfactory to the Company duly
     executed by the holder or by his duly authorized attorney.  In the
     case of any exchange, dividends on the Preferred Stock issuable
     upon such exchange will commence to accrue as of the most recent
     date as of which interest has been paid, or duly provided for, on
     the Notes unless no interest has been paid or duly provided for on
     the Notes, in which case from ____________, 1995 and no further
     adjustment will be made with regard to interest due on the Note,
     or portions thereof, so exchanged.  No adjustment in respect of
     interest or dividends will be made upon any conversion; provided,
     however, that if this Note shall be surrendered for conversion or
     exchange during the period from the close of business on any
     record date for the payment of interest through the close of
     business on the Business Day next preceding the following interest
     payment date, this Note (unless it or the portion being converted
     or exchanged shall have been called for redemption on a date in
     such period) must be accompanied by an amount, in funds acceptable
     to the Company, equal to the interest payable on such interest
     payment date on the principal amount being converted or exchanged. 
     No fractional shares will be issued upon any conversion or
     exchange, but an adjustment in cash will be made, as provided in
     the Indenture, in respect of any fraction of a share which would
     otherwise be issuable upon the surrender of any Note or Notes for
     conversion or exchange.

          Any Notes called for redemption, unless surrendered for
     conversion or exchange on or before the close of business on the
     date fixed for redemption, may be deemed to be purchased from the
     holder of such Notes at an amount equal to the applicable
     redemption price, together with accrued interest to the date fixed
     for redemption, by one or more investment bankers or other
     purchasers who may agree with the Company to purchase such Notes
     from the holders thereof and convert them into Common Stock or
     exchange them for Preferred Stock of the Company and to make
     payment for such Notes as aforesaid to the Trustee in trust for
     such holders.

          Upon due presentment for registration of transfer of this
     Note at the office or agency of the Company in the Borough of
     Manhattan, The City of New York, or at the option of the holder of
     this Note, at the Corporate Trust office of the Trustee, a new
     Note or Notes of authorized denominations for an equal aggregate
     principal amount will be issued to the transferee in exchange
     thereof, subject to the limitations provided in the Indenture,
     without charge except for any tax or other governmental charge
     imposed in connection therewith.

          The Company, the Trustee, any authenticating agent, any
     paying agent, any exchange or conversion agent and any Note
     registrar may deem and treat the registered holder hereof as the
     absolute owner of this Note (whether or not this Note shall be
     overdue and notwithstanding any notation of ownership or other
     writing hereon made by anyone other than the Company or any Note
     registrar), for the purpose of receiving payment hereof, or on
     account hereof, for the exchange or conversion hereof and for all
     other purposes, and neither the Company nor the Trustee nor any
     other authenticating agent nor any paying agent nor any other
     exchange or conversion agent nor any Note registrar shall be
     affected by any notice to the contrary.  All payments made to or
     upon the order of such registered holder shall, to the extent of
     the sum or sums paid, satisfy and discharge liability for monies
     payable on this Note.

          No recourse for the payment of the principal of or any
     premium or interest on this Note, or for any claim based hereon or
     otherwise in respect hereof, and no recourse under or upon any
     obligation, covenant or agreement of the Company in the Indenture
     or any indenture supplemental thereto or in any Note, or because
     of the creation of any indebtedness represented thereby, shall be
     had against any incorporator, stockholder, officer or director, as
     such, past, present or future, of the Company or of any Successor
     Company, either directly or through the Company or any Successor
     Company, whether by virtue of any constitution, statute or rule of
     law or by the enforcement of any assessment or penalty or
     otherwise, all such liability being, by the acceptance hereof and
     as part of the consideration for the issue hereof, expressly
     waived and released.

          Terms used in this Note and defined in the Indenture are used
     herein as therein defined.

               Pursuant to Section 151 of the General Corporation Law
     of the State of Delaware, SoftKey International Inc. (the
     "Company"), a corporation organized and existing under the
     General Corporation Law of the State of Delaware, in accordance
     with the provisions of Section 103 thereof, DOES HEREBY CERTIFY:

               That pursuant to the authority conferred upon the Board
     of Directors of the Company (the "Board of Directors") by Article
     4.2.2 of the Restated Certificate of Incorporation of the
     Company, as amended, and in accordance with the provisions of
     Section 151 of the General Corporation Law of the State of
     Delaware, the Board of Directors on November 30, 1995, adopted
     the following resolution authorizing and creating a series of
     Preferred Stock designated as 5-1/2% Series C Convertible
     Preferred Stock:

               RESOLVED that, pursuant to the authority vested in the
     Board of Directors in accordance with the provisions of the
     Restated Certificate of Incorporation, as amended, a series of
     the class of authorized Preferred Stock, par value $.01 per
     share, of the Company is hereby authorized and created and that
     the designation and number of shares thereof and the voting
     powers, preferences and relative, participating, optional and
     other special rights of the shares of such series, and the
     qualifications, limitations and restrictions thereof are as
     follows:

               Section 1.  Designation and Number.  

               Section 1.1  Designation.  The shares of such series
     shall be designated as "5-1/2% Series C Convertible Preferred
     Stock" (the "Series C Preferred Stock").  The maximum number of
     shares of Series C Preferred Stock hereby authorized shall be
     150,000 shares.

               Section 1.2  Priority.  The Series C Preferred Stock
     shall, with respect to the payment of dividends and the
     distribution of assets on liquidation, dissolution or winding up,
     (i) rank prior to the Common Stock, par value $0.01 per share, of
     the Company (the "Common Stock") and (ii) rank on a parity with
     any other series of Preferred Stock hereinafter issued by the
     Company.

               Section 2.  Dividends and Distributions.  

               Section 2.1  Dividends.  The holders of shares of
     Series C Preferred Stock, in preference to the holders of shares
     of Common Stock and of any shares of other capital stock of the
     Company ranking junior to the Series C Preferred Stock as to
     payment of dividends, shall be entitled to receive, when, as and
     if declared by the Board of Directors, out of the assets of the
     Company legally available therefor, dividends in the amount per
     share equal to 5-1/2% per annum of the Liquidation Preference (as
     defined herein) of such share payable or accrued semi-annually on
     May 1 and November 1 in each year commencing May 1, 1996 (each
     such date a "Dividend Payment Date") to the persons in whose
     names the Series C Preferred Stock is registered at the close of
     business on the April 15 and October 15 immediately preceding
     such Dividend Payment Date, as the case may be.  Such dividends
     shall begin to accrue on outstanding shares of Series C Preferred
     Stock from the date of issuance of such shares of Series C
     Preferred Stock; provided, in the case of any Series C Preferred
     Stock issued upon exchange for the Company's $150 million
     principal amount of 5-1/2% Senior Convertible/Exchangeable Notes
     due 2000 (the "Notes"), such dividend shall begin to accrue and
     accumulate from the date on which interest was last paid or duly
     provided for on such Notes, or if no interest has been paid or
     duly provided for prior to the date of such exchange, from
     December 22, 1995.  Dividends payable for any partial dividend
     period shall be computed on the basis of a 360-day year of twelve
     30-day months.  Dividends on the Series C Preferred Stock shall
     accrue on a daily basis whether or not funds shall be legally
     available for the payment thereof.  Accrued but unpaid dividends
     on the Series C Preferred Stock shall cumulate as of the Dividend
     Payment Date on which they first become payable, and any and all
     such accrued dividends shall be paid as provided in this Section
     2, Section 5 and Section 7.

               Section 2.2  No Additional Dividends.  The holders of
     shares of Series C Preferred Stock shall not be entitled to
     receive any dividends or other distributions except as provided
     herein.

               Section 3.  Voting Rights.  In addition to any voting
     rights provided by law, the holders of shares of Series C
     Preferred Stock shall have the following voting rights:

               Section 3.1  With Common Stock.  So long as the Series
     C Preferred Stock is outstanding, each share of Series C
     Preferred Stock shall entitle the holder thereof to vote on all
     matters voted on by holders of Common Stock voting together as a
     single class with other shares entitled to vote at all meetings
     of the stockholders of the Company.  With respect to any such
     vote, each share of Series C Preferred Stock shall entitle the
     holder thereof to cast the number of votes equal to the number of
     votes which could be cast in such vote by a holder of the shares
     of capital stock of the Company into which such share of Series C
     Preferred Stock is convertible on the record date for such vote.

               Section 3.2  As a Class.  The affirmative vote of the
     holders of at least 66-2/3% of the outstanding shares of Series C
     Preferred Stock, in person or by proxy, at a special or annual
     meeting of stockholders called for the purpose, shall be
     necessary to (i) authorize, increase the authorized number of
     shares of, or issue (including on conversion or exchange of any
     convertible or exchangeable securities or by reclassification),
     any shares of any class or classes of the Company's capital stock
     ranking prior to (either as to dividends or upon voluntary or
     involuntary liquidation, dissolution or winding up) the Series C
     Preferred Stock; (ii) increase the authorized number of shares
     of, or issue (including on conversion or exchange of any
     convertible or exchangeable securities or by reclassification)
     any shares of, Series C Preferred Stock, except in connection
     with the exchange of the Notes; (iii) authorize, adopt or approve
     an amendment to the Restated Certificate of Incorporation of the
     Company which would decrease the aggregate number of authorized
     shares of Series C Preferred Stock, increase or decrease the par
     value of the shares of Series C Preferred Stock, or alter or
     change the powers, preferences or special rights of the shares of
     Series C Preferred Stock so as to affect such shares of Series C
     Preferred Stock adversely; (iv) authorize or issue shares of any
     class or series of stock not authorized herein having any
     preference or priority as to dividends or assets superior to any
     such preference or priority of the Series C Preferred Stock; or
     (v) reclassify any shares of Common Stock or any other shares of
     capital stock of the Company other than the Series C Preferred
     Stock (such shares other than (A) shares of capital stock of the
     Company ranking senior (either as to dividends or upon
     liquidation, dissolution or winding up of the Company) to the
     Series C Preferred Stock and (B) Parity Stock (as hereinafter
     defined) are hereinafter referred to as "Junior Stock") into
     shares having any preference or priority as to dividends or
     liquidation superior to or on a parity with any such preference
     or priority of the Series C Preferred Stock; provided that Parity
     Stock may be reclassified into a different series of Parity Stock
     without the approval of the holders of Series C Preferred Stock.

               Section 3.3  Right to Elect Directors as a Class.  If
     on any date dividends payable on the Series C Preferred Stock
     shall have been in arrears and not paid in full for three semi-
     annual periods, whether or not consecutive, the number of
     directors constituting the Board of Directors shall, without
     further action, be increased by two and the holders of shares of
     Series C Preferred Stock shall have, in addition to the other
     voting rights set forth herein, the exclusive right, voting
     separately as a single class or as a class with the holders of
     shares of Parity Stock (as hereinafter defined), if such holders
     are then entitled to elect additional directors pursuant to any
     provision of the Certificate of Designation for such stock that
     is similar to this Section 3.3 ("Defaulted Parity Stock"), to
     elect the directors of the Company to fill such newly created
     directorships, the remaining directors to be elected by the other
     classes of stock entitled to vote therefor (including the Series
     C Preferred Stock in accordance with Section 3.1), at each
     meeting of stockholders held for the purpose of electing
     directors.  Such additional directors shall continue as directors
     and such additional voting right shall continue until such time
     as all dividends accumulated on the Series C Preferred Stock have
     been paid in full or all necessary funds have been set aside for
     payment, as the case may be, at which time such additional
     directors shall cease to be directors and such additional voting
     right of the holders of Series C Preferred Stock shall terminate
     subject to revesting in the event of each and every subsequent
     event of the character indicated above.  In no event shall the
     holders of Series C Preferred Stock and/or the holders of Parity
     Stock voting separately or together as a class be entitled to
     elect a total of more than two directors to the Board of
     Directors of the Company pursuant to this Section 3.3 and/or any
     similar provision of the Certificate of Designation for any
     Parity Stock.

               Section 3.4.1  Exercise.  The foregoing rights of
     holders of shares of Series C Preferred Stock to take any actions
     as provided in this Section 3 may be exercised at any annual
     meeting of stockholders or at a special meeting of stockholders
     held for such purpose as hereinafter provided or at any
     adjournment thereof, or by the written consent, delivered to the
     Secretary of the Company, of the holders of the minimum number of
     shares required to take such action.

               So long as such right to vote continues (and unless
     such right has been exercised by written consent of the minimum
     number of shares required to take such action), the Chairman of
     the Board of the Company may call, and, upon the written request
     of holders of record of 20% of the outstanding shares of Series C
     Preferred Stock, if the holders of Series C Preferred Stock are
     to vote separately as a single class, or the holders of record of
     20% of the outstanding shares of Series C Preferred Stock and
     Defaulted Parity Stock, if the holders of shares of Series C
     Preferred Stock are to vote as a class with the holders of shares
     of any Defaulted Parity Stock, addressed to the Secretary of the
     Company at the principal office of the Company, shall call a
     special meeting of the holders of shares entitled to vote as
     provided herein.  Such meeting shall be held within 30 days after
     delivery of such request to the Secretary, at the place and upon
     the notice provided by law and in the By-laws of the Company for
     the holding of meetings of stockholders.

               Section 3.4.2  Quorum.  At each meeting of stockholders
     at which the holders of shares of Series C Preferred Stock shall
     have the right, voting separately as a single class or as a class
     with the holders of shares of any Defaulted Parity Stock, to
     elect directors of the Company as provided in this Section 3 or
     to take any action, the presence in person or by proxy of the
     holders of record of one-third of the total number of shares of
     Series C Preferred Stock, if the holders of shares of Series C
     Preferred Stock are to vote separately as a single class, or the
     holders of record of one-third of the total number of shares of
     Series C Preferred Stock and Defaulted Parity Stock, if the
     holders of shares of Series C Preferred Stock are to vote as a
     class with the holders of shares of any Parity Stock, then
     outstanding and entitled to vote on the matter shall be necessary
     and sufficient to constitute a quorum.  At any such meeting or at
     any adjournment thereof:

               (i) the absence of a quorum of the holders of
          shares of Series C Preferred Stock, if the holders of
          Series C Preferred Stock are to vote separately as a
          single class, or the holders of shares of Series C
          Preferred Stock and Defaulted Parity Stock, if the
          holders of shares of Series C Preferred Stock are to
          vote as a class with the holders of shares of any
          Parity Stock, shall not prevent the election of
          directors other than those to be elected by the holders
          of shares of Series C Preferred Stock or the holders of
          shares of Series C Preferred Stock and Defaulted Parity
          Stock, as the case may be, and the absence of a quorum
          of the holders of shares of any other class or series
          of capital stock shall not prevent the election of
          directors to be elected by the holders of shares of
          Series C Preferred Stock or the holders of shares of
          Series C Preferred Stock and Defaulted Parity Stock, as
          the case may be, or the taking of any action as
          provided in this Section 3; and

               (ii) in the absence of a quorum of the holders of
          shares of Series C Preferred Stock, if the holders of
          Series C Preferred Stock are to vote separately as a
          single class, or the holders of shares of Series C
          Preferred Stock and Defaulted Parity Stock, if the
          holders of Series C Preferred Stock are to vote as a
          class with the holders of shares of any Defaulted
          Parity Stock, a majority of the holders of such shares
          present in person or by proxy shall have the power to
          adjourn the meeting as to the actions to be taken by
          the holders of shares of Series C Preferred Stock or
          the holders of shares of Series C Preferred Stock and
          Defaulted Parity Stock, as the case may be, from time
          to time and place to place without notice other than
          announcement at the meeting until a quorum shall be
          present.

               Section 3.4.3  Votes.  For the taking of any action as
     provided in Sections 3.2 and 3.3 by the holders of shares of
     Series C Preferred Stock or the holders of shares of Series C
     Preferred Stock and Defaulted Parity Stock, as the case may be,
     each such holder shall have one vote for each share of such stock
     standing in his name on the transfer books of the Company as of
     any record date fixed for such purpose or, if no such date be
     fixed, at the close of business on the Business Day (as defined
     in Section 11) next preceding the day on which notice is given,
     or if notice is waived, at the close of business on the Business
     Day next preceding the day on which the meeting is held.

               Section 3.4.4  Directors.  Each director elected by the
     holders of shares of Series C Preferred Stock or the holders of
     shares of Series C Preferred Stock and Defaulted Parity Stock, as
     the case may be, as provided in Section 3.3 shall, unless his
     term shall expire earlier, hold office until the annual meeting
     of stockholders next succeeding his election or until his
     successor, if any, is elected and qualified.

               In case any vacancy shall occur among the directors
     elected by the holders of shares of Series C Preferred Stock or
     the holders of shares of Series C Preferred Stock and Defaulted
     Parity Stock, as the case may be, as provided in Section 3.3,
     such vacancy may be filled for the unexpired portion of the term
     by vote of the remaining director theretofore elected by such
     holders (if there is a remaining director), or such director's
     successor in office.  If any such vacancy is not so filled within
     20 days after the creation thereof or if both directors so
     elected by the holders of Series C Preferred Stock or the holders
     of Series C Preferred Stock and Defaulted Parity Stock, as the
     case may be, shall cease to serve as directors before their terms
     shall expire, the holders of the Series C Preferred Stock or the
     holders of Series C Preferred Stock and Defaulted Parity Stock,
     as the case may be, then outstanding and entitled to vote for
     such directors may, by written consent as herein provided, or at
     a special meeting of such holders called as provided herein,
     elect successors to hold office for the unexpired terms of the
     directors whose places shall be vacant.

               Any director elected by the holders of shares of Series
     C Preferred Stock voting separately as a single class or the
     holders of shares of Series C Preferred Stock voting as a class
     with the holders of shares of Defaulted Parity Stock may be
     removed from office with or without cause by the vote or written
     consent of the holders of at least a majority of the outstanding
     shares of Series C Preferred Stock or a majority of the
     outstanding shares of Series C Preferred Stock and Defaulted
     Parity Stock, as the case may be.  A special meeting of the
     holders of shares of Series C Preferred Stock or the holders of
     shares of Series C Preferred Stock and Defaulted Parity Stock, as
     the case may be, may be called in accordance with the procedures
     set forth in Section 3.4.1.

     any capital stock of the Company ranking on a parity (either as
     to dividends or upon liquidation, dissolution or winding up of
     the Company) with the Series C Preferred Stock.

               Section 4.  Certain Restrictions.

     this Section 4.1 shall not apply upon the affirmative vote of the
     holders of 66-2/3% of the outstanding shares of Series C
     Preferred Stock.

               Section 4.2  Restrictions on Redemption or Purchase. 
     Whenever dividends payable on shares of Series C Preferred Stock
     as provided in Section 2 are not paid in full, thereafter and

     required to be applied by it to repurchase or otherwise acquire
     shares of Series C Preferred Stock and shares of such Parity

     of Designation for such stock, voting together as a class, shall
     have approved such repurchase or other acquisition; or (B) redeem
     or purchase or otherwise acquire for consideration any shares of
     Series C Preferred Stock; provided that the Company (1) may
     accept shares of Series C Preferred Stock surrendered for
     conversion into shares of capital stock of the Company pursuant
     to Section 8, or (2) may redeem shares of Series C Preferred
     Stock pro rata pursuant to Section 5.2; and provided, further,
     that the restrictions of this Section 4.2 shall not apply upon
     the affirmative vote of the holders of 66-2/3% of the outstanding
     shares of Series C Preferred Stock.

               Section 4.3  Purchase by Subsidiary.  The Company shall
     not permit any subsidiary of the Company to purchase or otherwise
     acquire for consideration any shares of capital stock of the
     Company unless the Company could, pursuant to Section 4.2,
     purchase such shares at such time and in such manner.

               Section 5.  Redemption.  

               Section 5.1  Redemption Prices.  The Company may, at
     its option, redeem all or from time to time any part of the
     Series C Preferred Stock on any date, upon notice as set forth in
     Section 5.2, and at the redemption prices set forth below,
     provided, however, that no such redemption shall be effected
     before November 2, 1998; provided, further, that, notwithstanding
     the foregoing, on November 1, 2000 the Company shall redeem all
     of the Series C Preferred Stock then outstanding.  The redemption
     prices (expressed as percentages of the liquidation value of
     $1,000.00), together in each case with accrued and unpaid 
     dividends thereon, whether or not declared, to the date of
     redemption, payable in cash, shall be as follows:

               If redeemed during the 12-month period beginning:

               Date                          Percentage

               November 1, 1998              102.2%
               November 1, 1999              101.1%

     and 100% on and after November 1, 2000.

               Section 5.2  Notice of Redemption, Selection of Series
     C Preferred Stock.  In case the Company shall desire to exercise
     the right to redeem all or, as the case may be, any part of the
     Series C Preferred Stock pursuant to Section 5.1, it shall fix a
     date for redemption and, in the case of any redemption pursuant
     to Section 5.1, it shall mail or cause to be mailed a notice of
     such redemption at least 30 and not more than 60 days prior to
     the date fixed for redemption to the holders of Series C
     Preferred Stock so to be redeemed as a whole or in part at their
     last addresses as the same appear on the books of the Company. 
     Such mailing shall be by first class mail.  The notice, if mailed
     in the manner herein provided, shall be conclusively presumed to
     have been duly given, whether or not the holder receives such
     notice.  In any case, failure to give such notice by mail or any
     defect in the notice to the holder of any Series C Preferred
     Stock designated for redemption as a whole or in part shall not
     affect the validity of the proceedings for the redemption of any
     other shares of Series C Preferred Stock.

               Each such notice of redemption shall specify the
     aggregate number of shares of Series C Preferred Stock to be
     redeemed, the date fixed for redemption, the redemption price at
     which Series C Preferred Stock is to be redeemed, the place or
     places of payment, that payment will be made upon presentation
     and surrender of certificates representing such Series C
     Preferred Stock, that dividends accrued to the date fixed for
     redemption will be paid as specified in said notice and that on
     and after said date, dividends thereon or on the portion thereof
     to be redeemed will cease to accrue.  Such notice shall also
     state the current Conversion Price (as defined below) and the
     date on which the right to convert such Series C Preferred Stock
     into Common Stock will expire.  If fewer than all the Series C
     Preferred Stock is to be redeemed, the notice of redemption shall
     identify the Series C Preferred Stock to be redeemed.

               On or prior to the Business Day prior to the redemption
     date specified in the notice of redemption given as provided in
     this Section, the Company will deposit with one or more paying
     agents (or, if the Company is acting as its own paying agent, set
     aside, segregate and hold in trust) an amount of money sufficient
     to redeem on the redemption date all the Series C Preferred Stock
     so called for redemption (other than those shares theretofore
     surrendered for conversion into Common Stock) at the appropriate
     redemption price, together with accrued dividends to the date
     fixed for redemption.  If any shares of Series C Preferred Stock
     called for redemption are converted pursuant hereto, any money
     deposited with any paying agent or so segregated and held in
     trust for the redemption of such shares of Series C Preferred
     Stock shall be paid to the Company upon its request or, if then
     held by the Company, shall be discharged from such trust.

               If fewer than all the shares of Series C Preferred
     Stock are to be redeemed, the Company shall select the shares of
     Series C Preferred Stock to be redeemed by lot or, in its sole
     discretion, on a pro rata basis. 

               Section 5.3  Payment of Series C Preferred Stock Called
     for Redemption.  If notice of redemption has been given as above
     provided, the Series C Preferred Stock with respect to which such
     notice has been given shall, unless converted into Common Stock
     pursuant to the terms hereof, become due and payable on the date
     and at the place or places stated in such notice at the
     applicable redemption price, together with dividends thereon
     accrued to the date fixed for redemption, and on and after said
     date (unless the Company shall default in the payment of such
     redemption price, together with dividends thereon accrued to said
     date), dividends on the Series C Preferred Stock so called for
     redemption shall cease to accrue, and such Series C Preferred
     Stock shall cease after the close of business on the Business Day
     next preceding the date fixed for redemption to be convertible
     into Common Stock and the holders thereof shall have no right in
     respect of such shares of Series C Preferred Stock except the
     right to receive the redemption price thereof and dividends
     thereon to the date fixed for redemption.  On presentation and
     surrender of Series C Preferred Stock at a place of payment in
     said notice specified, the said Series C Preferred Stock shall be
     paid and redeemed by the Company at the applicable redemption
     price, together with dividends accrued thereon to the date fixed
     for redemption.

               Section 5.4  Conversion Arrangement on Call for
     Redemption.  In connection with any redemption of Series C
     Preferred Stock, the Company may arrange for the purchase and
     conversion of any Series C Preferred Stock by an agreement with
     one or more investment bankers or other purchasers to purchase
     such Series C Preferred Stock by paying to the Company or a
     paying agent designated by the Company in trust for the holders
     of Series C Preferred Stock, on or before the date fixed for
     redemption, an amount not less than the applicable redemption
     price, together with dividends accrued to the date fixed for
     redemption, of such Series C Preferred Stock.  Notwithstanding
     anything to the contrary contained in this Section 5, the
     obligation of the Company to pay the redemption price of such
     Series C Preferred Stock, together with dividends accrued to the
     date fixed for redemption, shall be deemed to be satisfied and
     discharged to the extent such amount is so paid by such
     purchasers.  If such an agreement is entered into, any Series C
     Preferred Stock not duly surrendered for conversion by the
     holders thereof may, at the option of the Company, be deemed, to
     the fullest extent permitted by law, acquired by such purchasers
     from such holders and (notwithstanding anything to the contrary
     contained in Section 8) surrendered by such purchasers for
     conversion, all as of immediately prior to the close of business
     on the date fixed for redemption (and the right to convert any
     such Series C Preferred Stock shall be deemed to have been
     extended through such time), subject to payment of the above
     amount as aforesaid.  At the direction of the Company, any
     payment agent appointed by the Company shall hold and dispose of
     any such amount paid to it in the same manner as it would monies
     deposited with it by the Company for the redemption of Series C
     Preferred Stock.

               Section 5.5.  Purchase of Series C Preferred Stock Upon
     a Change of Control.

               Section 5.5.1  If a Change of Control (as defined in
     Section 11) shall occur at any time, then each holder of Series C
     Preferred Stock shall have the right to require that the Company
     purchase, to the extent that the Company shall have funds legally
     available therefor, such holder's shares of Series C Preferred
     Stock in whole or in part at a purchase price (the "Change of
     Control Purchase Price") in cash in an amount equal to 101% of
     the Liquidation Preference of such Series C Preferred Stock, plus
     accrued and unpaid dividends thereon, if any, to the repurchase
     date (the "Change of Control Purchase Date") pursuant to the
     offer described below (the "Change of Control Offer") and in
     accordance with the other procedures set forth herein.

               Section 5.5.2  Within 30 days following any Change of
     Control, the Company shall give written notice of such Change of
     Control to each holder of Series C Preferred Stock, by first-
     class mail, postage prepaid, at his address appearing on the
     books of the Company, stating, among other things:  that a Change
     of Control has occurred; the Change of Control Purchase Price and
     the Change of Control Purchase Date (which shall be a Business
     Day no earlier than 30 days nor later than 60 days from the date
     such notice is mailed, or such later date as is necessary to
     comply with requirements under the Exchange Act); that any shares
     of Series C Preferred Stock not tendered will continue to accrue
     dividends; that, unless the Company defaults in the payment of
     the Change of Control Purchase Price, any shares of Series C
     Preferred Stock accepted for payment pursuant to the Change of
     Control Offer shall cease to accrue dividends after the Change of
     Control Purchase Date; and certain other procedures that a holder
     of Series C Preferred Stock must follow to accept a Change of
     Control Offer or to withdraw such acceptance.

               Section 5.5.3  The Company will comply with the
     applicable tender offer rules, including Rule 13e-4 under the
     Exchange Act, and any other applicable securities laws or
     regulations in connection with a Change of Control Offer.

               Section 5.5.4  The Company will not, and will not
     permit any subsidiary to, create or permit to exist or become
     effective any restriction that would materially impair the
     ability of the Company to make a Change of Control Offer to
     purchase the Series C Preferred Stock or, if such Change of
     Control Offer is made, to pay for the Series C Preferred Stock
     tendered for purchase.

               Section 6.  Reacquired Shares.  Any shares of Series C
     Preferred Stock converted, redeemed, purchased or otherwise
     acquired by the Company in any manner whatsoever shall be retired
     and canceled promptly after the acquisition thereof.  All such
     shares of Series C Preferred Stock shall upon their cancellation,
     and upon the filing of an appropriate certificate with the
     Secretary of State of the State of Delaware, become authorized
     but unissued shares of Preferred Stock, par value $.01 per share,
     of the Company, undesignated as to series, and may be reissued as
     part of another series of Preferred Stock, par value $.01 per
     share, of the Company subject to the conditions or restrictions
     on issuance set forth herein.

               Section 7.  Liquidation, Dissolution or Winding Up. 

               Section 7.1  Bankruptcy or Insolvency.  If the Company
     shall commence a voluntary case under the Federal bankruptcy laws
     or any other applicable Federal or State bankruptcy, insolvency
     or similar law, or consent to the entry of an order for relief in
     an involuntary case under any such law or to the appointment of a
     receiver, liquidator, assignee, custodian, trustee, sequestrator
     (or other similar official) of the Company or of any substantial
     part of its property, or make an assignment for the benefit of
     its creditors, or admit in writing its inability to pay its debts
     generally as they become due, or if a decree or order for relief
     in respect of the Company shall be entered by a court having
     jurisdiction in the premises in an involuntary case under the
     Federal bankruptcy laws or any other applicable Federal or State
     bankruptcy, insolvency or similar law, or appointing a receiver,
     liquidator, assignee, custodian, trustee, sequestrator (or other
     similar official) of the Company or any substantial part of its
     property, or ordering the winding up or liquidation of its
     affairs, and any such decree or order shall be unstayed and in
     effect for a period of 90 consecutive days and on account of any
     such event the Company shall liquidate, dissolve or wind up, or
     if the Company shall otherwise liquidate, dissolve or wind up, no
     distribution shall be made (i) to the holders of shares of Junior
     Stock unless, prior thereto, the holders of shares of Series C
     Preferred Stock, subject to Section 8, shall have received the
     Liquidation Preference with respect to each share, or (ii) to the
     holders of shares of Parity Stock, except distributions made
     ratably on the Series C Preferred Stock and all Parity Stock in
     proportion to the total amounts to which the holders of all
     shares of the Series C Preferred Stock and Parity Stock are
     entitled upon such liquidation, dissolution or winding up. 
     "Liquidation Preference" shall mean $1,000.00 per share of Series
     C Preferred Stock, plus an amount equal to all accrued and unpaid
     dividends thereon.  After payment of the full amount to which the
     holders of Series C Preferred Stock are entitled as provided in
     this Section 7.1, such holders shall have no further right or
     claim to any of the remaining assets of the Company.

               Section 7.2  Consolidation or Merger.  Neither the
     consolidation, merger or other business combination of the
     Company with or into any other person or persons nor the sale,
     lease, exchange or other transfer of all or substantially all the
     assets of the Company shall be deemed to be a liquidation,
     dissolution or winding up of the Company for purposes of this
     Section 7.

               Section 7.3  Proportionate Amount.  The Liquidation
     Preference with respect to each fractional share of Series C
     Preferred Stock outstanding shall be equal to a ratably
     proportionate amount of the Liquidation Preference with respect
     to each outstanding share of Series C Preferred Stock.

                                    SECTION 8.

                      CONVERSION OF SERIES C PREFERRED STOCK

               Section 8.1  Right to Convert.  Subject to and upon
     compliance with the provisions of this Certificate of
     Designation, the holder of any share of Series C Preferred Stock
     shall have the right, at his option, at any time (except that,
     with respect to any shares of Series C Preferred Stock which
     shall be called for redemption or delivered for repurchase, such
     right shall terminate, except as provided in the third paragraph
     of Section 8.2, at the close of business on the last Trading Day
     prior to the date fixed for redemption of such shares of Series C
     Preferred Stock unless the Company shall default in payment due
     upon redemption thereof) to convert any such share into that
     number of fully paid and nonassessable shares of Common Stock (as
     such shares shall then be constituted) obtained by dividing
     $1,000.00 for each such share so converted by the Conversion
     Price in effect at such time, by surrender of the shares so to be
     converted in the manner provided in Section 8.2.  A holder of
     Series C Preferred Stock is not entitled to any rights of a
     holder of Common Stock until such holder has converted his Series
     C Preferred Stock to Common Stock, and only to the extent such
     Series C Preferred Stock is deemed to have been converted to
     Common Stock under this Section 8.

               Section 8.2  Exercise of Conversion Privilege; Issuance
     of Common Stock on Conversion; No Adjustment for Dividends.  In
     order to exercise the conversion privilege with respect to any
     Series C Preferred Stock, the holder of any such share of Series
     C Preferred Stock to be converted in whole or in part shall
     surrender such share of Series C Preferred Stock, duly endorsed,
     at the principal office of the Company or with the Transfer Agent
     for the Common Stock, and shall give written notice of conversion
     in the form provided on the share of Series C Preferred Stock (or
     such other notice which is acceptable to the Company) to the
     office or agency that the holder elects to convert such shares
     specified in said notice.  Such notice shall also state the name
     or names (with address) in which the certificate or certificates
     for shares of Common Stock which shall be issuable on such
     conversion shall be issued and shall be accompanied by transfer
     taxes, if required pursuant to Section 8.7.  Each such share
     surrendered for conversion shall, unless the shares issuable on
     conversion are to be issued in the same name as the registration
     of such share of Series C Preferred Stock, be duly endorsed by,
     or be accompanied by instruments of transfer in form satisfactory
     to the Company duly executed by, the holder or his duly
     authorized attorney.

               As promptly as practicable after satisfaction of the
     requirements for conversion set forth above, subject to
     compliance with any restrictions on transfer if shares issuable
     on conversion are to be issued in a name other than that of the
     shareholder (as if such transfer were a transfer of the shares so
     converted), the Company shall issue and shall deliver to such
     holder at the address designated in the notice of conversion, a
     certificate or certificates for the number of full shares
     issuable upon the conversion of such shares in accordance with
     the provisions of this Section 8 and a check or cash in respect
     of any fractional interest in respect of a share of Common Stock
     arising upon such conversion, as provided in Section 8.  In case
     any certificate shall be surrendered for partial conversion, the
     Company shall issue and deliver to the holder of the certificate
     so surrendered, without charge to him, a new certificate or
     certificates in an aggregate share amount equal to the
     unconverted portion of the surrendered certificate.

               Each conversion shall be deemed to have been effected as
     to any such certificate on the date on which the requirements set
     forth above in this Section 8.2 have been satisfied as to such
     certificate, and the person in whose name any certificate or
     certificates for shares of Common Stock shall be issuable upon
     such conversion shall be deemed to have become on said date the
     holder of record of the shares represented thereby; provided,
     however, that any such surrender on any date when the stock
     transfer books of the Company shall be closed shall constitute
     the person in whose name the certificates are to be issued as the
     record holder thereof for all purposes on the next succeeding day
     on which such stock transfer books are open, but such conversion
     shall be at the Conversion Price in effect on the date upon which
     such Series C Preferred Stock shall have been surrendered.

               Section 8.3  Cash Payments in Lieu of Fractional Shares. 
     No fractional shares of Common Stock or scrip representing
     fractional shares shall be issued upon conversion of Series C
     Preferred Stock.  If more than one certificate for shares of
     Preferred Stock shall be surrendered for conversion at one time
     by the same holder, the number of full shares which shall be
     issuable upon conversion shall be computed on the basis of the
     aggregate shares of Series C Preferred Stock (or specified
     portions thereof to the extent permitted hereby) so surrendered. 
     If any fractional share of stock would be issuable upon the
     conversion of any Series C Preferred Stock, the Company shall
     make an adjustment therefor in cash at the current market value
     thereof.  The current market value of a share of Common Stock
     shall be the Closing Price on the first Trading Day immediately
     preceding the day on which the Series C Preferred Stock is deemed
     to have been converted and such Closing Price shall be determined
     as provided in Section 8.5.7.

               Section 8.4  Conversion Price.  The conversion price
     shall be $53.00 (herein called the "Conversion Price") subject to
     adjustment as provided in this Section 8.

               Section 8.5 Adjustment of Conversion Price.  The
     Conversion Price shall be adjusted from time to time by the
     Company as follows:

               Section 8.5.1  In case the Company shall hereafter pay a
     dividend or make a distribution to all holders of the outstanding
     Common Stock in shares of Common Stock, the Conversion Price in
     effect at the opening of business on the date following the date
     fixed for the determination of stockholders entitled to receive
     such dividend or other distribution shall be reduced by
     multiplying such Conversion Price by a fraction the numerator of
     which shall be the number of shares of Common Stock outstanding
     at the close of business on the Record Date (as defined in
     Section 8.5.7) fixed for such determination and the denominator
     of which shall be the sum of such number of shares and the total
     number of shares constituting such dividend or other
     distribution, such reduction to become effective immediately
     after the opening of business on the day following the Record
     Date.  The Company will not pay any dividend or make any
     distribution on shares of Common Stock held in the treasury of
     the Company.

               Section 8.5.2  In case the Company shall issue rights or
     warrants to all holders of its outstanding shares of Common Stock
     entitling them (for a period expiring within 45 days after the
     date fixed for determination of stockholders entitled to receive
     such rights or warrants) to subscribe for or purchase shares of
     Common Stock at a price per share less than the Current Market
     Price (as defined in Section 8.5.7) on the Record Date fixed for
     determination of stockholders entitled to receive such rights or
     warrants, the Conversion Price shall be adjusted so that the same
     shall equal the price determined by multiplying the Conversion
     Price in effect at the opening of business on the date after the
     Record Date by a fraction the numerator of which shall be the
     number of shares of Common Stock outstanding at the close of
     business on the Record Date plus the number of shares which the
     aggregate offering price of the total number of shares so offered
     would purchase at such Current Market Price, and the denominator
     of which shall be the number of shares of Common Stock
     outstanding on the close of business on the Record Date plus the
     total number of additional shares of Common Stock so offered for
     subscription or purchase.  Such adjustment shall become effective
     immediately after the opening of business on the day following
     the Record Date fixed for determination of stockholders entitled
     to receive such rights or warrants.  To the extent that shares of
     Common Stock are not delivered after the expiration or
     termination of such rights or warrants, the Conversion Price
     shall be readjusted to the Conversion Price which would then be
     in effect had the adjustments made upon the issuance of such
     rights or warrants been made on the basis of delivery of only the
     number of shares of Common Stock actually delivered.  In the
     event that such rights or warrants are not so issued, the
     Conversion Price shall again be adjusted to be the Conversion
     Price which would then be in effect if such date fixed for the
     determination of stockholders entitled to receive such rights or
     warrants had not been fixed.  In determining whether any rights
     or warrants entitle the holders to subscribe for or purchase
     shares of Common Stock at less than such Current Market Price,
     and in determining the aggregate offering price of such shares of
     Common Stock, there shall be taken into account any consideration
     received for such rights or warrants, the value of such
     consideration, if other than cash, to be determined by the Board
     of Directors.

               Section 8.5.3  In case outstanding shares of Common
     Stock shall be subdivided into a greater number of shares of
     Common Stock, the Conversion Price in effect at the opening of
     business on the day following the day upon which such subdivision
     becomes effective shall be proportionately reduced, and
     conversely, in case outstanding shares of Common Stock shall be
     combined into a smaller number of shares of Common Stock, the
     Conversion Price in effect at the opening of business on the day
     following the day upon which such combination becomes effective
     shall be proportionately increased, such reduction or increase,
     as the case may be, to become effective immediately after the
     opening of business on the day following the day upon which such
     subdivision or combination becomes effective.

               Section 8.5.4  In case the Company shall, by dividend or
     otherwise, distribute to all holders of its Common Stock shares
     of any class of capital stock of the Company (other than any
     dividends or distributions to which Section 8.5.1 applies) or
     evidences of its indebtedness or assets (including securities,
     but excluding any rights or warrants referred to in Section
     8.5.2, and excluding any dividend or distribution (x) in
     connection with the liquidation, dissolution or winding-up of the
     Company, whether voluntary or involuntary, (y) exclusively in
     cash or (z) referred to in Section 8.5.1 (any of the foregoing
     hereinafter in this Section 8.5.4 called the "Securities")),
     then, in each such case, the Conversion Price shall be reduced so
     that the same shall be equal to the price determined by
     multiplying the Conversion Price in effect immediately prior to
     the close of business on the Record Date (as defined in Section
     8.5.7) with respect to such distribution by a fraction of which
     the numerator shall be the Current Market Price (determined as
     provided in Section 8.5.7) on such date less the fair market
     value (as determined by the Board of Directors, whose
     determination shall be conclusive and described in a resolution
     of such board) on such date of the portion of the Securities so
     distributed applicable to one share of Common Stock and the
     denominator shall be such Current Market Price, such reduction to
     become effective immediately prior to the opening of business on
     the day following the Record Date; provided, however, that in the
     event the then fair market value (as so determined) of the
     portion of the Securities so distributed applicable to one share
     of Common Stock is equal to or greater than the Current Market
     Price on the Record Date, in lieu of the foregoing adjustment,
     adequate provision shall be made so that each holder of Series C
     Preferred Stock shall have the right to receive upon conversion
     the amount of Securities such holder would have received had such
     holder converted each Series C Preferred Stock on such date.  In
     the event that such dividend or distribution is not so paid or
     made, the Conversion Price shall again be adjusted to be the
     Conversion Price which would then be in effect if such dividend
     or distribution had not been declared.  If the Board of Directors
     determines the fair market value of any distribution for purposes
     of this Section 8.5.4 by reference to the actual or when issued
     trading market for any securities comprising all or part of such
     distribution, it must in doing so consider the prices in such
     market over the same period used in computing the Current Market
     Price pursuant to Section 8.5.7 to the extent possible.

               Notwithstanding the foregoing provisions of this Section
     8.5.4, no adjustment shall be made hereunder for any distribution
     of Securities if the Company makes proper provision so that each
     holder of Series C Preferred Stock who converts such Series C
     Preferred Stock after the date fixed for determination of
     stockholders entitled to receive such distribution shall be
     entitled to receive upon such conversion, in addition to the
     shares of Common Stock issuable upon such conversion, the amount
     and kind of Securities that such holder would have been entitled
     to receive if such holder had, immediately prior to such
     determination date, converted such Series C Preferred Stock into
     Common Stock; provided that, with respect to any Securities that
     are convertible, exchangeable or exercisable, the foregoing
     provision shall only apply to the extent (and so long as) the
     Securities receivable upon conversion of such Series C Preferred
     Stock would be convertible, exchangeable or exercisable, as
     applicable, without any loss of rights or privileges for a period
     of at least 60 days following conversion of such Series C
     Preferred Stock.

               Rights or warrants distributed by the Company to all
     holders of Common Stock entitling the holders thereof to
     subscribe for or purchase shares of the Company's capital stock
     (either initially or under certain circumstances), which rights
     or warrants, until the occurrence of a specified event or events
     ("Trigger Event"): (i) are deemed to be transferred with such
     shares of Common Stock, (ii) are not exercisable and (iii) are
     also issued in respect of future issuances of Common Stock, shall
     not be deemed distributed for purposes of this Section 8.5.4 (and
     no adjustment to the Conversion Price under Section 8.5.4 will be
     required) until the occurrence of the earliest Trigger Event.  In
     addition, in the event of any distribution of rights or warrants,
     or any Trigger Event with respect thereto, that shall have
     resulted in an adjustment to the Conversion Price under this
     Section 8.5.4, (1) in the case of any such rights or warrants
     which shall all have been redeemed or repurchased without
     exercise by any holders thereof, the Conversion Price shall be
     readjusted upon such final redemption or repurchase to give
     effect to such distribution or Trigger Event, as the case may be,
     as though it were a cash distribution, equal to the per share
     redemption or repurchase price received by a holder of Common
     Stock with respect to such rights or warrants (assuming such
     holder had retained such rights or warrants), made to all holders
     of Common Stock as of the date of such redemption or repurchase,
     and (2) in the case of such rights or warrants all of which shall
     have expired or been terminated without exercise by any holder
     thereof, the Conversion Price shall be readjusted as if such
     issuance had not occurred.

               For purposes of this Section 8.5.4 and Sections 8.5.1
     and 8.5.2, any dividend or distribution to which this Section
     8.5.4 is applicable that also includes shares of Common Stock, or
     rights or warrants to subscribe for or purchase shares of Common
     Stock (or both), shall be deemed instead to be (1) a dividend or
     distribution of the evidences of indebtedness, assets or shares
     of capital stock other than such shares of Common Stock or rights
     or warrants (and any Conversion Price reduction required by this
     Section 8.5.4 with respect to such dividend or distribution shall
     then be made) immediately followed by (2) a dividend or
     distribution of such shares of Common Stock or such rights or
     warrants (and any further Conversion Price reduction required by
     Sections 8.5.1 and 8.5.2 with respect to such dividend or
     distribution shall then be made, except (A) the Record Date of
     such dividend or distribution shall be substituted as "the date
     fixed for the determination of stockholders entitled to receive
     such dividend or other distribution" and "the date fixed for such
     determination" within the meaning of Sections 8.5.1 and 8.5.2 and
     (B) any shares of Common Stock included in such dividend or
     distribution shall not be deemed "outstanding at the close of
     business on the date fixed for such determination" within the
     meaning of Section 8.5.1).

               Section 8.5.5  In case the Company shall, by dividend
     or otherwise, distribute to all holders of its Common Stock cash
     (excluding any cash that is distributed upon a merger or
     consolidation to which Section 8.6 applies or as part of a
     distribution referred to in Section 8.5.4) in an aggregate amount
     that, combined together with (1) the aggregate amount of any
     other such distributions to all holders of its Common Stock made
     exclusively in cash within the twelve (12) months preceding the
     date of payment of such distribution, and in respect of which no
     adjustment pursuant to this Section 8.5.5 has been made, and (2)
     the aggregate of any cash plus the fair market value (as
     determined by the Board of Directors, whose determination shall
     be conclusive and described in a resolution of such board) of
     consideration payable in respect of any tender offer, by the
     Company or any of its subsidiaries for all or any portion of the
     Common Stock concluded within the twelve (12) months preceding
     the date of payment of such distribution, and in respect of which
     no adjustment pursuant to Section 8.5.6 has been made, exceeds
     20.0% of the product of the Current Market Price (determined as
     provided in Section 8.5.7) on the Record Date with respect to
     such distribution times the number of shares of Common Stock
     outstanding on such date, then, and in each such case,
     immediately after the close of business on such date, unless the
     Company elects to reserve such cash for distribution to the
     holders of the Series C Preferred Stock upon the conversion of
     the Series C Preferred Stock so that any such holder converting
     Series C Preferred Stock will receive upon such conversion, in
     addition to the shares of Common Stock to which such holder is
     entitled, the amount of cash which such holder would have
     received if such holder had, immediately prior to the Record Date
     for such distribution of cash, converted its Series C Preferred
     Stock into Common Stock, the Conversion Price shall be reduced so
     that the same shall equal the price determined by multiplying the
     Conversion Price in effect immediately prior to the close of
     business on such date by a fraction (i) the numerator of which
     shall be equal to the Current Market Price on the Record Date
     less an amount equal to the quotient of (x) the excess of such
     combined amount over such 20.0% and (y) the number of shares of
     Common Stock outstanding on the Record Date and (ii) the
     denominator of which shall be equal to the Current Market Price
     on such date; provided, however, that in the event the portion of
     the cash so distributed applicable to one share of Common Stock
     is equal to or greater than the Current Market Price of the
     Common Stock on the Record Date, in lieu of the foregoing
     adjustment, adequate provision shall be made so that each Series
     C Preferred Stock shareholder shall have the right to receive
     upon conversion the amount of cash such holder would have
     received had such holder converted each share of Series C
     Preferred Stock on the Record Date.  In the event that such
     dividend or distribution is not so paid or made, the Conversion
     Price shall again be adjusted to be the Conversion Price which
     would then be in effect if such dividend or distribution had not
     been declared.

               Section 8.5.6  In case a tender offer made by the
     Company or any of its subsidiaries for all or any portion of the
     Common Stock shall expire and such tender offer (as amended upon
     the expiration thereof) shall require the payment to stockholders
     (based on the acceptance (up to any maximum specified in the
     terms of the tender offer) of Purchased Shares (as defined
     below)) of an aggregate consideration having a fair market value
     (as determined by the Board of Directors, whose determination
     shall be conclusive and described in a resolution of such board)
     that combined together with (1) the aggregate of the cash plus
     the fair market value (as determined by the Board of Directors,
     whose determination shall be conclusive and described in a
     resolution of such board), as of the expiration of such tender
     offer, of consideration payable in respect of any other tender
     offer, by the Company or any of its subsidiaries for all or any
     portion of the Common Stock expiring within the twelve (12)
     months preceding the expiration of such tender offer, and in
     respect of which no adjustment pursuant to this Section 8.5.6 has
     been made, and (2) the aggregate amount of any distributions to
     all holders of the Company's Common Stock made exclusively in
     cash within twelve (12) months preceding the expiration of such
     tender offer, and in respect of which no adjustment pursuant to
     Section 8.5.5 has been made, exceeds 20.0% of the product of the
     Current Market Price (determined as provided in Section 8.5.7) as
     of the last time (the "Expiration Time") tenders could have been
     made pursuant to such tender offer (as it may be amended) times
     the number of shares of Common Stock outstanding (including any
     tendered shares) on the Expiration Time, then, and in each such
     case, immediately prior to the opening of business on the day
     after the date of the Expiration Time, the Conversion Price shall
     be adjusted so that the same shall equal the price determined by
     multiplying the Conversion Price in effect immediately prior to
     close of business on the date of the Expiration Time by a
     fraction of which the numerator shall be the number of shares of
     Common Stock outstanding (including any tendered shares) on the
     Expiration Time multiplied by the Current Market Price of the
     Common Stock on the Trading Day next succeeding the Expiration
     Time and the denominator shall be the sum of (x) the fair market
     value (determined as aforesaid) of the aggregate consideration
     payable to stockholders based on the acceptance (up to any
     maximum specified in the terms of the tender offer) of all shares
     validly tendered and not withdrawn as of the Expiration Time (the
     shares deemed so accepted, up to any such maximum, being referred
     to as the "Purchased shares") and (y) the product of the number
     of shares of Common Stock outstanding (less any Purchased Shares)
     on the Expiration Time and the Current Market Price of the Common
     Stock on the Trading Day next succeeding the Expiration Time,
     such reduction to become effective immediately prior to the
     opening of business on the day following the Expiration Time.  In
     the event that the Company is obligated to purchase shares
     pursuant to any such tender offer, but the Company is permanently
     prevented by applicable law from effecting any such purchases or
     all such purchases are rescinded, the Conversion Price shall
     again be adjusted to be the Conversion Price which would then be
     in effect if such tender offer had not been made.

               Section 8.5.7  For purposes of this section 8.5, the
     following terms shall have the meaning indicated:

               (1)  "Closing Price" with respect to any securities on
          any day shall mean the closing sale price regular way on such day
          or, in case no such sale takes place on such day, the average of
          the reported closing bid and asked prices, regular way, in each
          case on the New York Stock Exchange, or, if such security is not
          listed or admitted to trading on such Exchange, on the principal
          national security exchange or quotation system on which such
          security is quoted or listed or admitted to trading, or, if not
          quoted or listed or admitted to trading on any national
          securities exchange or quotation system, the average of the
          closing bid and asked prices of such security on the over-the-
          counter market on the day in question as reported by the National
          Quotation Bureau Incorporated, or a similar generally accepted
          reporting service, or if not so available, in such manner as
          furnished by any New York Stock Exchange member firm selected
          from time to time by the Board of Directors for that purpose, or
          a price determined in good faith by the Board of Directors, whose
          determination shall be conclusive and described in a resolution
          of such board.

                   (2)  "Current Market Price" shall mean the average of
          the daily Closing Prices per share of Common Stock for the ten
          consecutive Trading Days immediately prior to the date in
          question; provided, however, that (1) if the "ex" date (as
          hereinafter defined) for any event (other than the issuance or
          distribution or Change of Control requiring such computation)
          that requires an adjustment to the Conversion Price pursuant to
          Section 8.5.1, 8.5.2, 8.5.3, 8.5.4, 8.5.5 or 8.5.6 occurs during
          such ten consecutive Trading Days, the Closing Price for each
          Trading Day prior to the "ex" date for such other event shall be
          adjusted by multiplying such Closing Price by the same fraction
          by which the Conversion Price is so required to be adjusted as a
          result of such other event, (2) if the "ex" date for any event
          (other than the issuance, distribution or Change of Control
          requiring such computation) that requires an adjustment to the
          Conversion Price pursuant to Section 8.5.1, 8.5.2, 8.5.3, 8.5.4,
          8.5.5 or 8.5.6 occurs on or after the "ex" date for the issuance
          or distribution requiring such computation and prior to the day
          in question, the Closing Price for each Trading Day on and after
          the "ex" date for such other event shall be adjusted by
          multiplying such Closing Price by the reciprocal of the fraction
          by which the Conversion Price is so required to be adjusted as a
          result of such other event and (3) if the "ex" date for the
          issuance, distribution or Change of Control requiring such
          computation is prior to the day in question, after taking into
          account any adjustment required pursuant to clause (1) or (2) of
          this proviso, the Closing Price for each Trading Day on or after
          such "ex" date shall be adjusted by adding thereto the amount of
          any cash and the fair market value (as determined by the Board of
          Directors in a manner consistent with any determination of such
          value for purposes of Section 8.5.4 or 8.5.6, whose determination
          shall be conclusive and described in a resolution of such board)
          of the evidences of indebtedness, shares of capital stock or
          assets being distributed applicable to one share of Common Stock
          as of the close of business on the day before such "ex" date. 
          For purposes of any computation under Section 8.5.6, the Current
          Market Price of the Common Stock on any date shall be deemed to
          be the average of the daily Closing Prices per share of Common
          Stock for such day and the next two succeeding Trading Days;
          provided, however, that if the "ex" date for any event (other
          than the tender or exchange offer requiring such computation)
          that requires an adjustment to the Conversion Price pursuant to
          Section 8.5.1, 8.5.2, 8.5.3, 8.5.4, 8.5.5 or 8.5.6 occurs on or
          after the Expiration Time for the tender or exchange offer
          requiring such computation and prior to the day in question, the
          Closing Price for each Trading Day on and after the "ex" date for
          such other event shall be adjusted by multiplying such Closing
          Price by the reciprocal of the fraction by which the Conversion
          Price is so required to be adjusted as a result of such other
          event.  For purposes of this paragraph, the term "ex" date, (1)
          when used with respect to any issuance or distribution, means the
          first date on which the Common Stock trades regular way in the
          relevant exchange or in the relevant market from which the
          Closing Price was obtained without the right to receive such
          issuance or distribution, (2) when used with respect to any
          subdivision or combination of shares of Common Stock, means the
          first date on which the Common Stock trades regular way on such
          exchange or in such market after the time at which such
          subdivision or combination becomes effective and (3) when used
          with respect to any tender or exchange offer means the first date
          on which the Common Stock trades regular way on such exchange or
          in such market after the expiration of such offer. 
          Notwithstanding the foregoing, whenever successive adjustments to
          the Conversion Price are called for pursuant to this Section 8.5,
          such adjustments shall be made to the Current Market Price as may
          be necessary or appropriate to effectuate the intent of this
          Section 8.5 and to avoid unjust or inequitable results as
          determined in good faith by the Board of Directors.

                   (3)  "fair market value" shall mean the amount which a
          willing buyer would pay a willing seller in an arm's-length
          transaction.

                   (4)  "Record Date" shall mean, with respect to any
          dividend, distribution or other transaction or event in which the
          holders of Common Stock have the right to receive any cash,
          securities or other property or in which the Common Stock (or
          other applicable security) is exchanged for or converted into any
          combination of cash, securities or other property, the date fixed
          for determination of stockholders entitled to receive such cash,
          securities or other property (whether such date is fixed by the
          Board of Directors or by statute, contract or otherwise).

                   (5)  "Trading Day" shall mean (x) if the applicable
          security is listed or admitted for trading on the New York Stock
          Exchange or another national security exchange, a day on which
          the New York Stock Exchange or that other national security
          exchange is open for business or (y) if the applicable security
          is quoted on the Nasdaq National Market, a day on which trades
          may be made thereon or (z) if the applicable security is not so
          listed, admitted for trading or quoted, any day other than a
          Saturday or Sunday or a day on which banking institutions in the
          State of New York are authorized or obligated by law or executive
          order to close.

                   Section 8.5.8  The Company may make such reductions in
          the Conversion Price, in addition to those required by Sections
          8.5.1, 8.5.2, 8.5.3, 8.5.4, 8.5.5 and 8.5.6 as the Board of
          Directors considers to be advisable to avoid or diminish any
          income tax to holders of Common Stock or rights to purchase
          Common Stock resulting from any dividend or distribution of stock
          (or rights to acquire stock) or from any event treated as such
          for income tax purposes.  To the extent permitted by applicable
          law, the Company from time to time may reduce the Conversion
          Price by any amount for any period of time if the period is at
          least 20 days, the reduction is irrevocable during the period and
          the Board of Directors shall have made a determination that such
          reduction would be in the best interests of the Company, which
          determination shall be conclusive and described in a resolution
          of such board.  Whenever the Conversion Price is reduced pursuant
          to the preceding sentence, the Company shall mail to all holders
          of record of the Series C Preferred Stock a notice of the
          reduction at least 15 days prior to the date the reduced
          Conversion Price takes effect, and such notice shall state the
          reduced Conversion Price and the period it will be in effect.

                   Section 8.5.9  No adjustment in the Conversion Price
          shall be required unless such adjustment would require an
          increase or decrease of at least 1% in such price; provided,
          however, that any adjustments which by reason of this Section
          8.5.9 are not required to be made shall be carried forward and
          taken into account in any subsequent adjustment.  All
          calculations under this Section 8 shall be made by the Company
          and shall be made to the nearest cent or to the nearest one one-
          hundredth of a share, as the case may be.

                  No adjustment need be made for rights to purchase Common
          Stock pursuant to a Company plan for reinvestment of dividends or
          interest.

                  No adjustment need be made for a change in the par value,
          or to or from no par value, of the Common Stock.

                  To the extent the Series C Preferred Stock becomes
          convertible into cash, assets, property or securities (other than
          Common Stock of the Company), no adjustment need be made
          thereafter as to the cash, assets, property or such securities
          (except as such securities may otherwise by their terms provide),
          and interest shall not accrue on such cash.

                  Section 8.5.10  In any case in which this Section 8.5
          provides that an adjustment shall become effective immediately
          after a Record Date for an event, the Company may defer until the
          occurrence of such event (i) issuing to the holder of any Series
          C Preferred Stock converted after such Record Date and before the
          occurrence of such event the additional shares of Common Stock
          issuable upon such conversion by reason of the adjustment
          required by such event over and above the Common Stock issuable
          upon such conversion before giving effect to such adjustment and
          (ii) paying to such holder any amount in cash in lieu of any
          fraction pursuant to Section 8.3.

                  Section 8.6  Effect of Reclassification, Consolidation,
          Merger or Sale.  If any of the following events occur, namely (i)
          any reclassification or change of outstanding shares of Common
          Stock (other than a change in par value, or to or from no par
          value, as a result of a subdivision or combination), (ii) any
          consolidation, merger, or combination of the Company with another
          corporation as a result of which holders of Common Stock shall be
          entitled to receive stock, securities or other property or assets
          (including cash) with respect to or in exchange for such Common
          Stock or (iii) any sale or conveyance of the properties and
          assets of the Company as, or substantially as, an entirety to any
          other corporation as a result of which holders of Common Stock
          shall be entitled to receive stock, securities or other property
          or assets (including cash) with respect to or in exchange for
          such Common Stock, (each of the foregoing being referred to as a
          "Transaction"), each share of Series C Preferred Stock then
          outstanding shall thereafter be convertible into the kind and
          amount of shares of stock and other securities or property or
          assets (including cash) receivable upon such reclassification,
          change, consolidation, merger, combination, sale or conveyance by
          a holder of a number of shares of Common Stock issuable upon
          conversion of such share of Series C Preferred Stock (assuming,
          for such purposes, a sufficient number of authorized shares of
          Common Stock available to convert all such Series C Preferred
          Stock) immediately prior to such reclassification, change,
          consolidation, merger, combination, sale or conveyance, assuming
          each holder of Common Stock did not exercise his rights of
          election, if any, as to the kind or amount of securities, cash or
          other property receivable upon such reclassification, change,
          consolidation, merger, combination, sale or conveyance (provided
          that, if the kind or amount of securities, cash or other property
          receivable upon such reclassification, change, consolidation,
          merger, combination, sale or conveyance is not the same for each
          share of Common Stock in respect of which such rights of election
          shall not have been exercised ("non-electing share"), then for
          the purposes of this Section 8.6 the kind and amount of
          securities, cash or other property receivable upon such
          reclassification, change, consolidation, merger, combination,
          sale or conveyance for each non-electing share shall be deemed to
          be the kind and amount so receivable per share by a plurality of
          the non-electing shares).

                  Notwithstanding anything contained herein to the
          contrary, the Company will not effect any Transaction unless,
          prior to the consummation thereof, (i) the Surviving Person
          thereof shall assume, by written instrument mailed to each holder
          of shares of Series C Preferred Stock if such shares are held by
          50 or fewer holders or groups of affiliated holders or to each
          Transfer Agent for the shares of Series C Preferred Stock if such
          shares are held by a greater number of holders, the obligation to
          deliver to such holder such stock, securities or other property
          or assets (including cash) with respect to or in exchange for
          Common Stock to which, in accordance with the foregoing
          provisions, such holder is entitled and (ii) proper provision is
          made to ensure that the holders of shares of Series C Preferred
          Stock will be entitled to receive the benefits afforded by
          Section 8.6.  Such written instrument should provide for
          adjustments which shall be as nearly as equivalent as may be
          practicable to the adjustments provided for in this Section 8.6.

                  The above provisions of this Section shall similarly
          apply to successive reclassifications, changes, consolidations,
          mergers, combinations, sales and conveyances.  

                  If this Section 8.6 applies to any event or occurrence,
          Section 8.5 shall not apply.

                  Section 8.7  Transfer or Similar Taxes on Shares Issued. 
          The issue of stock certificates on conversions of Series C
          Preferred Stock shall be made without charge to the converting
          holder of Series C Preferred Stock for any transfer or similar
          tax in respect of the issue thereof.  The Company shall not,
          however, be required to pay any such tax which may be payable in
          respect of any transfer involved in the issue and delivery of
          stock in any name other than that of the holder of any Series C
          Preferred Stock converted, and the Company shall not be required
          to issue or deliver any such stock certificate unless and until
          the person or persons requesting the issue thereof shall have
          paid to the Company the amount of such tax or shall have
          established to the satisfaction of the Company that such tax has
          been paid.

                  Section 8.8  Reservation of Shares; Shares to Be Fully
          Paid; Listing of Common Stock.  The Company shall provide, free
          from preemptive rights, out of its authorized but unissued shares
          or shares held in treasury, sufficient shares to provide for the
          conversion of the Series C Preferred Stock from time to time as
          such Series C Preferred Stock is presented for conversion.

                  Before taking any action which would cause an adjustment
          reducing the Conversion Price below the then par value, if any,
          of the shares of Common Stock issuable upon conversion of the
          Series C Preferred Stock, the Company will take all corporate
          action which may, in the opinion of its counsel, be necessary in
          order that the Company may validly and legally issue shares of
          such Common Stock at such adjusted Conversion Price.

                  The Company covenants that all shares of Common Stock
          which may be issued upon conversion of Series C Preferred Stock
          will, upon issue, be fully paid and nonassessable by the Company
          and free from all transfer or similar taxes as described in
          Section 8.7, liens and charges with respect to the issue thereof.

                  The Company further covenants that, if at any time the
          Common Stock shall be listed on the New York Stock Exchange or
          any other national securities exchange, the Company will, if
          permitted by the rules of such exchange, list and keep listed, so
          long as the Common Stock shall be so listed on such exchange, all
          Common Stock issuable upon conversion of the Series C Preferred
          Stock.

                  Section 8.9  Notice to Stockholders Prior to Certain
          Actions.  In case:

               (a)  the Company makes any distribution or dividend that
          would require an adjustment in the Conversion Price pursuant to
          Section 8.5; or

               (b)  the Company takes any action that would result in a
          Transaction as defined in Section 8.6; or

               (c)  of the voluntary or involuntary dissolution,
          liquidation or winding-up of the Company,

          the Company shall cause to be mailed to each holder of Series C
          Preferred Stock at his address appearing on the books of the
          Company, as promptly as possible but in any event at least 15
          days prior to the applicable date hereinafter specified, a notice
          stating (x) the date on which a record date is to be taken for
          the purpose of such dividend, distribution, rights or warrants,
          or, if a record is not to be taken, the date as of which the
          holders of Common Stock of record to be entitled to such
          dividend, distribution, rights or warrants are to be determined
          or (y) the date on which such reclassification, change,
          consolidation, merger, sale, conveyance, transfer, dissolution,
          liquidation or winding-up is expected to become effective or
          occur and the date as of which it is expected that holders of
          record of Common Stock shall be entitled to exchange their Common
          Stock for securities or other property deliverable upon such
          reclassification, change consolidation, merger, sale, conveyance,
          transfer, dissolution, liquidation or winding-up.  Failure to
          give such notice, or any defect therein, shall not affect the
          legality or validity of such dividend, distribution,
          reclassification, change, consolidation, merger, sale,
          conveyance, transfer, dissolution, liquidation or winding-up. 
          Neither the failure to give such notice nor any defect therein
          shall affect the legality or validity of the proceedings
          referenced in clauses (a) through (c) of this Section 8.9.

                    Section 9.  Reports as to Adjustments.  Upon any
          adjustment of the Conversion Price then in effect and any
          increase or decrease in the number of shares of Common Stock
          issuable upon the operation of the conversion set forth in
          Section 8, then, and in each such case, the Company shall
          promptly deliver to the Transfer Agent for the Series C Preferred
          Stock and the Transfer Agent for the Common Stock, a certificate
          signed by the President or a Vice President and by the Treasurer
          or an Assistant Treasurer or the Secretary or an Assistant
          Secretary of the Company setting forth in reasonable detail the
          event requiring the adjustment and the method by which such
          adjustment was calculated and specifying the Conversion Price
          then in effect following such adjustment and the increased or
          decreased number of shares issuable upon the conversion set forth
          in Section 8.  The Company shall also promptly after the making
          of such adjustment give written notice to the registered holders
          of the Series C Preferred Stock at the address of each holder as
          shown on the books of the Company maintained by the Transfer
          Agent thereof, which notice shall state the Conversion Price then
          in effect, as adjusted, and the increased or decreased number of
          shares issuable upon the exercise of the right of conversion
          granted by Section 8, and shall set forth in reasonable detail
          the method of calculation of each with a brief statement of the
          facts requiring such adjustment.  Where appropriate, such notice
          to holders of the Series C Preferred Stock may be given in
          advance and included as part of the notice required under the
          provisions of Section 8.9.

                    Section 10.  Certain Covenants.  Any registered holder
          of Series C Preferred Stock may proceed to protect and enforce
          its rights and the rights of such holders by any available remedy

          rights, whether for the specific enforcement of any provision in

          Stock] [Common Stock] are being transferred in a transaction not
          involving any public offering within the United States within the
          meaning of the Securities Act and that the [Notes] [Preferred
          Stock] and the shares of [Preferred Stock and] Common Stock
          issuable upon conversion [or exchange] thereof (collectively, the

          registered under the Securities Act or any applicable state
          securities laws, and the undersigned agrees, on the undersigned's
          own behalf and on behalf of each account for which the
          undersigned acquires any Securities, that if in the future the
          undersigned decides to resell or otherwise transfer such
          Securities, such Securities may be resold or otherwise
          transferred only (a) to the Company or any subsidiary thereof,
          (b) to a person who is a "qualified institutional buyer" (as

          meeting the requirements of Rule 144A, (c) to an Institutional

          the trustee (or transfer agent, as the case may be) for such
          Securities a signed letter containing certain representations and
          agreements relating to the restrictions on transfer of such
          Securities (the form of which letter can be obtained from such
          trustee, or transfer agent, as the case may be), (d) outside the
          United States in a transaction meeting the requirements of
          Regulation S under the Securities Act, (e) pursuant to the
          exemption from registration provided by Rule 144 under the
          Securities Act (if applicable) or (f) pursuant to a registration
          statement which has been declared effective under the Securities
          Act.  The undersigned agrees that any such transfer of Securities
          referred to in this paragraph shall be in accordance with
          applicable securities laws of any State of the United States or
          any other applicable jurisdiction and in accordance with the
          legends set forth on the Securities.  The undersigned further
          agrees to provide any person purchasing any of the Securities
          from the undersigned a notice advising such purchaser that
          resales of such Securities are restricted as stated herein.  The
          undersigned understands that the registrar and transfer agent for
          the Securities will not be required to accept for registration or
          transfer any Securities, except upon presentation of evidence
          satisfactory to the Company that the foregoing restrictions on
          transfer have been complied with.  The undersigned further
          understands that any Securities will be in the form of definitive
          physical certificates and that such certificates will bear a
          legend (unless the sale of the Securities has been registered
          under the Securities Act) reflecting the substance of this
          paragraph.

                    The undersigned acknowledges that the Company, others
          and you will rely upon the undersigned's confirmations,
          acknowledgements and agreements set forth herein, and the
          undersigned agrees to notify you promptly in writing if any of

                         Registration Statement on Form S-3

          Ladies and Gentlemen:

                    I am Vice President and General Counsel of
          SoftKey International Inc., a Delaware corporation (the
          "Company"), and am issuing this opinion in connection
          with the filing today of a Registration Statement on Form
          S-3 (the "Registration Statement") with the Securities
          and Exchange Commission (the "Commission") relating to
          the registration by the Company of (a) $150,000,000
          aggregate principal amount of 51/2% Senior
          Convertible/Exchangeable Notes due 2000 of the Company
          (the "Notes"), (b) 150,000 shares of 51/2% Series C
          Convertible Preferred Stock, par value $.01 per share, of
          the Company (the "Series C Preferred Stock") issuable
          upon exchange thereof, (c) 2,830,188 (or such other
          number as may be issuable upon conversion of the Notes or
          the Series C Preferred Stock as a result of the
          antidilution provisions thereof) shares of common stock,
          par value $.01 per share, of the Company (the "Common
          Stock") issuable upon conversion of the Notes or the
          Series C Preferred Stock (such shares together with the
          Notes and the Series C Preferred Stock, the "Securities")
          and (d) 5,052,697 shares of Common Stock issued pursuant
          to the Agreement and Plan of Merger (the "Merger
          Agreement") dated November 30, 1995 by and among the
          Company, Cubsco I Inc., a California corporation, Cubsco
          II Inc., a Delaware corporation, Tribune Company, a
          Delaware corporation ("Tribune"), Compton's NewMedia,
          Inc., a California corporation, and Compton's Learning
          Company, a Delaware corporation (the "Comptons Shares"),
          in each case to be sold by the holder of the Securities
          (the "Selling Holder").  The Notes were originally issued
          under an Indenture dated as of December 22, 1995 (the
          "Indenture") by and between the Company and State Street
          Bank and Trust Company, as trustee (the "Trustee")
          pursuant to a Securities Purchase Agreement dated as of
          November 30, 1995 between the Company and Tribune (the
          "Securities Purchase Agreement").

                    This opinion is being furnished in accordance
          with the requirements of Item 601(b)(5) of Regulation S-K
          under the Securities Act of 1933, as amended (the "Act"). 
          Capitalized terms used and not otherwise defined herein
          shall have the respective meanings set forth in the
          Registration Statement.

                    In connection with this opinion and as General
          Counsel of the Company, I have examined originals or
          copies, certified or otherwise identified to my
          satisfaction, of:  (i) the Registration Statement; (ii)
          the Indenture; (iii) the Securities Purchase Agreement;
          (iv) the Merger Agreement; (v) the Restated Certificate
          of Incorporation of the Company, as amended, as currently
          in effect; (vi) the Bylaws of the Company, as amended, as
          currently in effect; and (vii) resolutions of the Board
          of Directors of the Company and the Pricing Committee
          appointed by the Board of Directors of the Company
          relating to, among other things, the issuance and sale of
          the Notes and the Comptons Shares by the Company, the
          filing of the Registration Statement and certain related
          matters.  I have also examined originals or copies,
          certified or otherwise identified to my satisfaction, of
          such records of the Company and such agreements,
          certificates of public officials, certificates of other
          officers or representatives of the Company and others and
          such other documents, certificates and records as I have
          deemed necessary or appropriate as a basis for the
          opinions set forth herein.

                    In my examination, I have assumed the legal
          capacity of all natural persons, the genuineness of all
          signatures, the authenticity of all documents submitted
          to me as originals, the conformity to original documents
          of all documents submitted to me as certified or
          photostatic copies and the authenticity of the originals
          of such latter documents.

                    I am admitted to the Bar in the Commonwealth of
          Massachusetts and do not purport to be an expert on, or
          express any opinion concerning, any law other than the
          substantive law of the Commonwealth of Massachusetts.

                    Based upon and subject to the limitations,
          qualifications, exceptions and assumptions set forth
          herein, I am of the opinion that:

                              1.   The Notes have been duly
          authorized by requisite corporate action on the part of
          the Company, constitute valid and binding obligations of
          the Company, enforceable against the Company in
          accordance with their terms, and are entitled to the
          benefits (and are subject to all of the limitations)
          provided for in the Indenture, except to the extent that
          (a) enforcement may be subject to or limited by (i)
          bankruptcy, insolvency, reorganization, moratorium or
          other similar laws now or hereafter in effect relating to
          creditors' rights and remedies generally and (ii) general
          principles of equity (regardless of whether such
          enforcement may be sought in a proceeding in equity or at
          law) and (b) the provisions contained in Section 16.13 of
          the Indenture may be deemed unenforceable.

                              2.   The Series C Preferred Stock
          initially issuable upon exchange of the Notes and the
          shares of Common Stock initially issuable upon conversion
          of the Notes or the Series C Preferred Stock have been
          duly authorized by the Company and, when issued and
          delivered upon such conversion in accordance with the
          applicable terms and provisions of the Notes, the
          Indenture or the Series C Preferred Stock, as the case
          may be, will be validly issued, fully paid and
          nonassessable.

                              3.   The Comptons Shares have been
          duly authorized and validly issued by the Company and are
          fully paid and nonassessable.

                    I hereby consent to the filing of this opinion
          with the Commission as an exhibit to the Registration
          Statement.  I also consent to the reference to my name
          under the caption "Legal Matters" in the Registration
          Statement.  In giving this consent, I do not thereby
          admit that I am included in the category of persons whose
          consent is required under Section 7 of the Act or the
          rules and regulations of the Commission thereunder.

                                        Very truly yours,

                                        /s/ Neal S. Winneg

           Earnings deficiency            $(60,165)

          For the purpose of computing the ratio of earnings to
          fixed charges, earnings consist of the sum of (i)
          earnings before income taxes and (ii) fixed charges. 
          Fixed charges consist of interest on all indebtedness and
          amortization of debt-related expenses.  At December 31,
          1995, the Company had paid no dividends on any Preferred
          Stock.  At December 31, 1995, fixed charges exceeded
          earnings by $60,165, which includes the effect of
          amortization and merger-related costs.  Excluding the
          effect of amortization and merger-related costs, the
          ratio of earnings to fixed charges at December 31, 1995
          would have been 8.39X.  Fixed charges prior to 1995 were
          deemed immaterial by the Company.
