                        AGREEMENT AND PLAN OF MERGER

               THIS MERGER AGREEMENT is made and entered into this
     30th day of November, 1995, by and among SoftKey International
     Inc., a Delaware corporation ("Buyer"), Cubsco I Inc., a
     California corporation ("CUBSCO I"), Cubsco II Inc., a Delaware
     corporation ("CUBSCO II"), Tribune Company, a Delaware
     corporation ("Seller"), Compton's NewMedia, Inc., a California
     corporation ("CNI"), and Compton's Learning Company, a Delaware
     corporation ("CLC" and, together with CNI, the "Companies").

               WHEREAS, Seller is the owner of all of the issued and
     outstanding capital stock of CNI and CLC; and

               WHEREAS, Buyer desires to acquire CNI and CLC upon the
     terms and subject to conditions set forth in this Agreement;

               NOW, THEREFORE, in consideration of the foregoing and
     the respective representations, warranties, covenants, agreements
     and conditions hereinafter set forth, and intending to be legally
     bound hereby, the parties hereto agree as follows:

                                 ARTICLE I

                               THE CNI MERGER

               1.1.  General.  This Agreement and the form of Merger
     Agreement attached hereto as Exhibit A (the "CNI Merger
     Agreement") provide for a merger (the "CNI Merger") of CUBSCO I
     with and into CNI, with CNI being the surviving corporation.  In
     the CNI Merger, it is contemplated that the then outstanding
     shares of CNI's common stock ("CNI Common Stock") will be
     converted at the CNI Effective Time (as hereinafter defined) into
     the right to receive, at or subsequent to the Closing (as
     hereinafter defined), an aggregate number of shares, rounded up
     to the nearest whole share (the "CNI SoftKey Shares"), of Buyer's
     common stock, par value $.01 per share ("SoftKey Common Stock"),
     obtained by dividing $104,500,000 by the volume-weighted average
     of the closing prices for SoftKey Common Stock as quoted over the
     Nasdaq National Market for the 10 full trading days ending on the
     second full trading day prior to the CNI Effective Time.

               1.2.  Conversion of CUBSCO I Stock.  Each share of
     CUBSCO I's common stock, par value $.01 per share ("CUBSCO I
     Stock"), issued and outstanding immediately prior to the CNI
     Effective Time shall, by virtue of the CNI Merger and without any
     action on the part of the holder thereof, be converted into and
     exchangeable for one share of common stock of CNI ("New CNI
     Stock") as the CNI Surviving Corporation (as hereinafter
     defined).  From and after the CNI Effective Time, each
     outstanding certificate theretofore representing shares of CUBSCO
     I Stock shall be deemed for all purposes to evidence ownership of
     and to represent the number of shares of New CNI Stock into which
     such CUBSCO I Stock shall have been converted.  Promptly after
     the CNI Effective Time, the CNI Surviving Corporation shall issue
     to Buyer a stock certificate or certificates representing shares
     of New CNI Stock in exchange for the certificate or certificates
     which formerly represented shares of CUBSCO I Stock (which shall
     be cancelled).

               1.3.  Conversion of CNI Common Stock.  Each share of
     CNI Common Stock issued and outstanding immediately prior to the
     CNI Effective Time, other than shares of CNI Common Stock which
     are held by CNI or by Buyer or any subsidiary of Buyer (which
     shares will be cancelled at the CNI Effective Time), shall, by
     virtue of this Agreement and without any action on the part of
     the holder thereof, be converted into the right to receive the
     number of shares of SoftKey Common Stock obtained by dividing the
     CNI SoftKey Shares by the number of shares of CNI Common Stock
     outstanding immediately prior to the CNI Effective Time.  In
     reliance on the representations and warranties of Seller
     contained in Sections 4.19 and 4.20 hereof, Buyer will deliver to
     Seller at the Closing a stock certificate or certificates
     representing the CNI SoftKey Shares upon surrender of the
     certificate(s) representing the shares of CNI Common Stock so
     converted.

               1.4.  CNI Surviving Corporation.  In accordance with
     the provisions of this Agreement and the California General
     Corporation Law ("CGCL"), at the CNI Effective Time, CUBSCO I
     shall be merged with and into CNI, and CNI shall be the surviving
     corporation (the "CNI Surviving Corporation") and shall continue
     its corporate existence under the CGCL.  The name of the CNI
     Surviving Corporation shall continue to be Compton's NewMedia,
     Inc.  The separate corporate existence of CUBSCO I shall
     terminate at the CNI Effective Time.

               1.5.  Effect of the CNI Merger.  At the CNI Effective
     Time, the CNI Merger shall have the effect provided for under the
     CGCL.

               1.6.  Organizational Documents.  The Articles of
     Incorporation of CNI, as in effect at the CNI Effective Time,
     shall be the Articles of Incorporation of the CNI Surviving
     Corporation until thereafter amended as provided by law.  The By-
     Laws of CNI, as in effect immediately prior to the CNI Effective
     Time, shall be the By-Laws of the CNI Surviving Corporation,
     until amended as provided by law and the express terms of the By-
     Laws.  At the Closing, Seller or CNI shall deliver or cause to be
     delivered to Buyer the stock book, stock ledger, minute book and
     corporate seal, if any, of CNI.

               1.7.  Directors and Officers.  The directors and
     officers of the CNI Surviving Corporation shall consist of the
     directors and officers of CUBSCO I immediately prior to the
     Effective Time, each to hold office in accordance with the CGCL,
     the Articles of Incorporation of the CNI Surviving Corporation
     and the By-Laws of the CNI Surviving Corporation.  Seller shall
     use reasonable efforts to deliver or cause to be delivered to
     Buyer at the Closing the written resignations of all of the
     officers and directors of CNI from their positions as officers or
     directors, effective as of the CNI Effective Time.

               1.8.  CNI Effective Time.  The CNI Merger shall be
     effected by the filing of the CNI Merger Agreement (together with
     the officer's certificate of each of CUBSCO I and CNI required
     under Section 1103 of the CGCL) with the Secretary of State of
     the State of California on the day of the Closing.  The term "CNI
     Effective Time" shall be the date and time when the CNI Merger
     becomes effective, as set forth in the CNI Merger Agreement.

               1.9.  Tax Consequences.  It is intended that the CNI
     Merger shall constitute a reorganization within the meaning of
     Section 368(a) of the Code Internal Revenue Code of 1986, as
     amended (the "Code"), and that this Agreement shall constitute a
     "plan of reorganization" for the purposes of Section 368 of the
     Code.

                                 ARTICLE II

                               THE CLC MERGER

               2.1.  General.  This Agreement and the Certificate of
     Merger attached hereto as Exhibit B (the "CLC Merger
     Certificate") provide for a merger (the "CLC Merger" and,
     together with the CNI Merger, the "Mergers") of CUBSCO II with
     and into CLC, with CLC being the surviving corporation.  In the
     CLC Merger, it is contemplated that the then outstanding shares
     of CLC's common stock, par value $1.00 per share (the "CLC Common
     Stock"), will be converted at the CLC Effective Time (as
     hereinafter defined) into the right to receive, at or subsequent
     to the Closing, an aggregate number of shares, rounded up to the
     nearest whole share (the "CLC SoftKey Shares" and, together with
     the CNI SoftKey Shares, the "SoftKey Shares"), of SoftKey Common
     Stock obtained by dividing $2,000,000 by the volume-weighted
     average of the closing prices for SoftKey Common Stock as quoted
     over the Nasdaq National Market for the 10 full trading days
     ending on the second full trading day prior to the CLC Effective
     Time.

               2.2.  Conversion of CUBSCO II Stock.  Each share of
     CUBSCO II's common stock, par value $.01 per share ("CUBSCO II
     Stock"), issued and outstanding immediately prior to the CLC
     Effective Time shall, by virtue of the CLC Merger and without any
     action on the part of the holder thereof, be converted into and
     exchangeable for one share of common stock, par value $1.00 per
     share, of CLC ("New CLC Stock") as the CLC Surviving Corporation
     (as hereinafter defined).  From and after the CLC Effective Time,
     each outstanding certificate theretofore representing shares of
     CUBSCO II Stock shall be deemed for all purposes to evidence
     ownership of and to represent the number of shares of New CLC
     Stock into which such CUBSCO II Stock shall have been converted. 
     Promptly after the CLC Effective Time, the CLC Surviving
     Corporation shall issue to Buyer a stock certificate or
     certificates representing shares of New CLC Stock in exchange for
     the certificate or certificates which formerly represented shares
     of CUBSCO II Stock (which shall be cancelled).

               2.3.  Conversion of CLC Common Stock.  Each share of
     CLC Common Stock issued and outstanding immediately prior to the
     CLC Effective Time, other than shares of CLC Common Stock which
     are held by CLC or by Buyer or any subsidiary of Buyer (which
     shares will be cancelled at the CLC Effective Time), shall, by
     virtue of this Agreement and without any action on the part of
     the holder thereof, be converted into the right to receive the
     number of CLC SoftKey Shares obtained by dividing the total
     number of CLC SoftKey Shares by the number of shares of CLC
     Common Stock outstanding immediately prior to the CLC Effective
     Time.  In reliance on the representations and warranties of
     Seller contained in Sections 4.19 and 4.20 hereof, Buyer will
     deliver to Seller at the Closing a stock certificate or
     certificates representing the CLC SoftKey Shares upon surrender
     of the certificate(s) representing the shares of CLC Common Stock
     so converted.

               2.4.  CLC Surviving Corporation.  In accordance with
     the provisions of this Agreement and the General Corporation Law
     of the State of Delaware (the "DGCL"), at the CLC Effective Time,
     CUBSCO II shall be merged with and into CLC, and CLC shall be the
     surviving corporation (the "CLC Surviving Corporation") and shall
     continue its corporate existence under the DGCL.  The name of the
     CLC Surviving Corporation shall continue to be Compton's Learning
     Company.  The separate corporate existence of CUBSCO II shall
     terminate at the CLC Effective Time.

     Laws of CLC, as in effect immediately prior to the CLC Effective
     Time, shall be the By-Laws of the CLC Surviving Corporation,
     until amended as provided by law and the express terms of the By-
     Laws.  At the Closing, Seller or CLC shall deliver or cause to be
     delivered to Buyer the stock book, stock ledger, minute book and
     corporate seal, if any, of CLC.

               2.7.  Directors and Officers.  The directors and

                                 ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF SELLER

               Seller hereby represents, warrants and agrees as
     follows:

               4.1.  Corporate Organization.

                    (a)  Seller is a corporation duly organized,
     validly existing and in good standing under the laws of the State
     of Delaware and has the corporate power and authority to own or
     lease its properties and to carry on its business as it is
     presently being conducted.

                    (b)  CNI is a corporation duly organized, validly
     existing and in good standing under the laws of the State of
     California, and CLC is a corporation duly organized, validly 
     existing and in good standing under the laws of the State of
     Delaware.  The Companies have the corporate power and authority
     to own or lease their respective properties and to carry on their
     respective businesses (collectively, the "NewMedia Business") as
     they are presently being conducted.  The Companies are duly
     qualified or licensed as foreign corporations to do business and
     are in good standing in the respective jurisdictions listed in
     Section 4.1(b) of the disclosure schedule delivered by Seller to
     Buyer on or prior to the date hereof (the "Disclosure Schedule"),
     which constitute every jurisdiction where the character of the
     Companies' respective properties (owned or leased) or the nature
     of their respective activities makes such qualification or
     licensure necessary, except for failures, if any, to be so
     qualified or licensed which would not in the aggregate have a
     Material Adverse Effect (as hereinafter defined).  As used in
     this Agreement, any reference to any event, change or effect
     having a "Material Adverse Effect" shall mean that such event,
     change or effect is materially adverse to the business,
     operations, properties, assets (including intangible assets),
     liabilities (including contingent liabilities), financial
     condition or results of operations of the Companies, taken
     together.

                    (c)  Except as set forth in Section 4.1(c)(i) of
     the Disclosure Schedule, the Companies do not own, directly or
     indirectly, any capital stock of any corporation or have any
     direct or indirect equity or ownership interest of any kind in
     any business, joint venture, partnership or other entity.  The
     copies of the Articles of Incorporation or Certificate of
     Incorporation and By-Laws of each of the Companies heretofore
     delivered to Buyer and set forth in Section 4.1(c)(ii) of the
     Disclosure Schedule are complete and correct copies of such
     instruments as presently in effect.

               4.2.  Authorization.  Each of Seller and the Companies
     has requisite corporate power and corporate authority to enter
     into this Agreement and the other agreements, documents and
     instruments to be executed and delivered by each of them pursuant
     hereto (the "Additional Seller's Documents") and to carry out the
     transactions contemplated hereby and thereby.  The Board of
     Directors of Seller and the Board of Directors and sole
     stockholder of each of the Companies have taken all action
     required by law, their respective charters, their respective By-
     Laws or otherwise to be taken by each of them to authorize the
     execution, delivery and performance of this Agreement and the
     Additional Seller's Documents, and when fully executed and
     delivered, this Agreement and the Additional Seller's Documents
     will constitute the valid and binding agreements of each of them,
     as the case may be, enforceable against each of them, as the case
     may be, in accordance with their respective terms.

               4.3.  Capitalization.

                    (a)  As of the date and time of execution of this
     Agreement, the authorized capital stock of CNI (the issued and
     outstanding shares of which are referred to hereinafter as the
     "CNI Shares") consists of:  (i) 10,000,000 shares of CNI Common
     Stock, 1,173,333 of which are issued and outstanding; and (ii)
     5,000,000  shares of preferred stock, of which 762,000 shares of
     Series A Preferred Stock (the "Series A Preferred Stock") are
     issued and outstanding, 561,375 shares of Series B Preferred
     Stock (the "Series B Preferred Stock") are issued and
     outstanding, and 450,101 shares of Series C Preferred Stock (the
     "Series C Preferred Stock") are issued and outstanding.  All of
     the CNI Shares have been validly issued, are fully paid,
     nonassessable and free and clear of any mortgage, pledge,
     security interest, encumbrance, lien, claim or charge of any kind
     or right of others of whatever nature ("Liens"), preemptive
     rights or other restrictions with respect thereto and are owned
     of record and beneficially by Seller.  There are no securities
     outstanding which are convertible into or exercisable or
     exchangeable for shares of capital stock of CNI, and there are no
     outstanding options, rights, contracts, warrants, subscriptions,
     conversion rights or other agreements or commitments pursuant to
     which CNI may be required to purchase, redeem, issue or sell any
     shares of capital stock or other securities of CNI or in any way
     relating to the issuance or voting of any capital stock or other
     securities of CNI.

                    (b)  As of the date and time of execution of this
     Agreement, the authorized capital stock of CLC consists of 10,000
     shares of CLC Common Stock, 1,000 of which are issued and
     outstanding (the "CLC Shares").  All of the CLC Shares have been
     validly issued, are fully paid, nonassessable and free of any
     Liens, preemptive rights or other restrictions with respect
     thereto and are owned of record and beneficially by Seller. 
     There are no securities outstanding which are convertible into or
     exercisable or exchangeable for shares of capital stock of CLC,
     and there are no outstanding options, rights, contracts,
     warrants, subscriptions, conversion rights or other agreements or
     commitments pursuant to which CLC may be required to purchase,
     redeem, issue or sell any shares of capital stock or other
     securities of CLC or in any way relating to the issuance or
     voting of any capital stock or other securities of CLC.

               4.4.  Ownership of Shares.  Seller has good and valid
     title to the CNI Shares and the CLC Shares, and at the CNI
     Effective Time and the CLC Effective Time, respectively, Buyer
     will have good and valid title to the New CNI Stock and the New
     CLC Stock, in each case, free and clear of any Liens (except for
     Liens created by or through Buyer).

               4.5.  Consents and Approvals; Non-Contravention. 
     Except as set forth in Section 4.5 of the Disclosure Schedule,
     neither the execution, delivery or performance of this Agreement
     or of any of the Additional Seller's Documents, nor the
     consummation by Seller and the Companies of the transactions
     contemplated hereby or thereby, nor compliance by Seller and the
     Companies with any of the provisions hereof or thereof will (a)
     violate any provision of the Charter or By-Laws of Seller or
     either of the Companies, (b) except as may be required under the
     Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
     (the "HSR Act"), require any filing with, or permit,
     authorization, consent or approval of, any court, arbitral
     tribunal, administrative agency or commission or other
     governmental or regulatory authority or agency (a "Governmental
     Entity"), (c) violate any order, writ, injunction, decree,
     statute, rule or regulation applicable to Seller or either of the
     Companies or any of their respective properties or assets or (d)
     require any consent, approval or authorization under any
     contract, lease or other agreement, or result in a violation or
     breach of, or constitute (with or without notice or lapse of time
     or both) a default (or give rise to any right of termination,
     amendment, cancellation or acceleration or any loss of a material
     benefit) under, or result in the creation or imposition of (or
     the obligation to create or impose) any Lien upon any of the
     respective properties or assets of Seller or either of the
     Companies under, any note, bond, mortgage, indenture, lease,
     license, contract, agreement or other instrument or obligation to
     which Seller or either of the Companies is a party or by which
     Seller or either of the Companies or any of their respective
     properties or assets may be bound, except, (i) in the case of
     clause (c), for such violations of statutes, rules or
     regulations, and (ii) in the case of clause (d), for such
     violations, breaches, defaults or Liens which, in either such
     case, would not materially impair the ability of Seller to
     perform its obligations hereunder or under any other agreements
     entered into between Buyer and Seller, either alone or together
     with other parties thereto, as of the date of this Agreement and
     which would not, either individually or in the aggregate, have a
     Material Adverse Effect.

               4.6.  Financial Statements.  The unaudited balance
     sheets of each of the Companies as of December 25, 1994 and
     September 24, 1995 and the unaudited operating statements of each
     of the Companies for the year ended December 25, 1994 and the
     nine months ended September 24, 1995, heretofore delivered to
     Buyer and set forth in Section 4.6 of the Disclosure Schedule
     (collectively, the "Financial Statements"), fairly present the
     financial condition of each Company as of the dates and for the
     periods indicated (subject in the case of interim statements to
     normal recurring year-end adjustments) and, except as disclosed
     in writing to Buyer in Section 4.6 of the Disclosure Schedule,
     have been prepared in accordance with generally accepted
     accounting principles as historically and consistently applied,
     subject to the absence of footnote disclosure.

     in any material transaction other than in, the ordinary course of

     Business and consistent with past practice;

                    (d)  suffered any damage, destruction or loss of
     property, whether or not covered by insurance, which has had or

     whether in writing or otherwise, to take any of, the actions
     described elsewhere in this Section 4.7.

               4.8.  No Undisclosed Liabilities.  Except as set forth
     in Section 4.8 of the Disclosure Schedule and as and to the
     extent of the amounts specifically reflected or reserved against
     in the Financial Statements (including without limitation
     charges, accruals and reserves for Taxes), and other than current
     liabilities which were incurred, and obligations under
     agreements, commitments or contracts entered into, in the
     ordinary course of the NewMedia Business and consistent with past
     practice and not in excess of current requirements and other than
     liabilities which could not reasonably be expected to have a
     Material Adverse Effect, the Companies have no liabilities or
     obligations of any nature (whether absolute or accrued, known or
     unknown, contingent or otherwise and whether due or to become
     due), including without limitation liabilities for Taxes.

               4.9.  Litigation.  Except as set forth in Section 4.9
     of the Disclosure Schedule, there is no claim, action, suit,
     inquiry, proceeding or investigation by or before any
     Governmental Entity pending or, to the knowledge of Seller,
     threatened against Seller or either of the Companies or affecting
     any of the respective properties or assets of Seller or the
     Companies which could, either individually or in the aggregate,
     reasonably be expected to have a Material Adverse Effect, or
     which in any manner (a) seeks injunctive or other non-monetary
     relief which relief is reasonably likely to cause a Material
     Adverse Effect or (b) seeks to prevent, enjoin, alter or delay
     any transaction contemplated hereby.  Neither Seller nor either
     of the Companies is subject to any order, writ, injunction or
     decree which, individually or in the aggregate, has or in the
     future could reasonably be expected to have a Material Adverse
     Effect or a material adverse effect on the ability of Seller to
     consummate the transactions contemplated hereby.

               4.10.  No Violation.  Neither Seller nor either of the
     Companies is in breach or violation of, or in default under (and
     no event has occurred which with notice or lapse of time or both
     would constitute such a breach, violation or default), any term,
     condition or provision of (a) their respective Charter or By-
     Laws, (b) any order, writ, decree, statute, rule or regulation
     applicable to Seller or either of the Companies or any of their
     respective properties or assets or (c) any note, bond, mortgage,
     indenture, lease, license, contract, agreement or other
     instrument or obligation to which Seller or either of the
     Companies is a party or by which Seller or either of the
     Companies or any of their respective properties or assets may be
     bound, except, in the case of clauses (a), (b) and (c), for such
     breaches, violations or defaults, which, when taken individually
     or in the aggregate, would neither materially impair the ability
     of Seller to perform its obligations hereunder or under any other
     agreement entered into between Buyer and Seller, either alone or
     together with other parties thereto, as of the date of this
     Agreement and which would not, either individually or in the
     aggregate, have a Material Adverse Effect.  To the best knowledge
     of Seller, the Companies have, and are in compliance with, all
     licenses, permits, variances, exemptions, orders, approvals and
     other authorizations of all Governmental Entities as are
     necessary in order to enable them to own and conduct the NewMedia
     Business as currently conducted and to enter into the
     transactions contemplated hereby, the lack of which, under
     applicable law, rule or regulation, (x) would render legally
     impermissible the transactions contemplated by this Agreement, or
     (y) could reasonably be expected to have a Material Adverse
     Effect.

               4.11.  NewMedia Business; Title to Assets.

                    (a)  The NewMedia Business as currently conducted
     consists of (i) the development, publication and worldwide
     distribution of interactive multimedia CD-ROM Software in the
     areas of reference (including "Compton's Interactive
     Encyclopedia" and related titles), education, entertainment and
     lifestyle and (ii) such other businesses, operations, properties,
     assets (including intangible assets) and liabilities (including
     contingent liabilities) as are conducted, held, utilized or had
     by the Companies as of the date and time of execution of this
     Agreement.

                    (b)  Either CNI or CLC has good and marketable
     title, free and clear of all Liens (other than Liens for current
     taxes not yet due and minor imperfections of title or minor
     encumbrances, if any, which in the aggregate do not materially
     detract from the value of the property subject thereto or impair
     in any material respect the continued use by the Companies of the
     property subject thereto for the use being made thereof), to all
     of the material assets, real property, interest in real property,
     rights, franchises, licenses and properties tangible or
     intangible, real or personal, wherever located, which are used in
     or necessary for the conduct of the NewMedia Business in
     substantially the same manner as it is presently conducted (the
     "Assets"), other than Intellectual Property (as hereinafter
     defined) and property that is leased or licensed.  Either CNI or
     CLC has valid and enforceable leases or licenses, as the case may
     be, with respect to the Assets consisting of property that is
     leased or licensed (other than Intellectual Property), under
     which there exists no default, event of default or event which,
     with notice or lapse of time or both, would constitute a default,
     except for such defaults which would not have, either
     individually or in the aggregate, a Material Adverse Effect.

               4.12.  Intellectual Property.  (a) Except as set forth
     in Section 4.12(a) of the Disclosure Schedule, which shall be
     delivered by Seller to Buyer on or before December 15, 1995,
     either CNI or CLC owns, licenses or otherwise has the right to
     use, sell, or license the Intellectual Property (as defined in
     this subparagraph 4.12(a)) as used in the NewMedia Business as
     heretofore conducted. Section 4.12 of the Disclosure Schedule, to
     be delivered by Seller to Buyer on or before December 15, 1995,
     shall include a true and complete listing of the following:  (i)
     Section 4.12(a)(i) shall list all issued patents and pending
     patent applications, registered trademarks and service marks and
     applications therefor, and copyright registrations and
     applications ("Registered Intellectual Property") which are owned
     by CNI or CLC; (ii) Section 4.12(a)(ii) shall list all other
     products and titles (including print, CD-ROM and online titles
     and computer programs) which are not the subject of copyright

     properties, facilities or operations of either of the Companies
     is in violation of any federal, state or local law, ordinance,
     regulation or order relating to industrial hygiene or to the
     environmental conditions on, under or about such properties or
     facilities, including, but not limited to, soil and ground water

     Companies have owned or leased their respective properties and
     facilities, neither of the Companies has used, generated,
     manufactured or stored on, under or about such properties or
     facilities or transported to or from such properties or
     facilities any Hazardous Materials.

                    (c)  To the knowledge of Seller, during the time
     that the Companies have owned or leased their respective
     properties and facilities, there has been no litigation brought
     or, to the best knowledge of Seller, threatened against and no
     request for information made to Seller or either of the Companies
     by, or any settlement reached by Seller or either of the
     Companies with, any party or parties alleging the presence,
     disposal, release or threatened release of any oil or petroleum
     or Hazardous Materials on, from or under any of such properties
     or facilities.

               4.23.  Taxes.

     extensions or comparable consents;

                         (v)  no audit or other proceeding by any

     Return of Seller which relates to Taxes of either of the

     or signed an agreement with any taxing authority which is
     reasonably likely to have a Material Adverse Effect;

                         (viii) Seller (as to the Companies and the
     NewMedia Business) and the Companies have each complied in all
     material respects with all applicable laws, rules and regulations
     relating to the payment and withholding of Taxes of the Companies

     Companies;

                         (xi) neither Seller (as to either of the

     agreement, contract or arrangement that could result, separately
     or in the aggregate, in the payment of any "excess parachute
     payments" within the meaning of Section 280G of the Code;

                         (xii) neither of the Companies is, nor has
     been during the applicable period specified in Section
     897(c)(1)(A)(ii) of the Code, a United States real property
     holding company (as defined in Section 897(c)(2) of the Code);

                         (xiii) neither the Companies nor the Seller
     (nor any member of a "controlled group" (within the meaning of

     Companies or the Seller) have participated in, or cooperated
     with, an "international boycott" within the meaning of Section
     999 of the Code;

                         (xiv) neither of the Companies is subject to

     Treasury Regulation SECTION 1.1502-6) for U.S. federal income taxes of
     the affiliated group of corporations of which Seller is the
     common parent corporation and which includes the Companies,
     neither of the Companies is subject to liability for Taxes of any
     other person, including, without limitation, liability arising
     from the application of U.S. Treasury Regulation SECTION 1.1502-6 or
     any analogous provision of Tax law.

                    (b)  For purposes of this Agreement, "Taxes"
     (including, with correlative meaning, the term "Tax") shall mean
     all taxes, charges, fees, levies or other assessments, including,
     without limitation, all net income, gross income, gross receipts,
     sales, use, service, service use, ad valorem, transfer,
     franchise, profits, license, withholding, Social Security,

     other additional amounts imposed thereon or with respect thereto,
     by any taxing authority (domestic or foreign).

               4.24.  Benefit Plans.

                    (a)  A true and complete list of each Benefit
     Plan, and each other "employee benefit plan" (within the meaning
     of Section 3(2) of the Employee Retirement Income Security Act of
     1974, as amended, and the rules and regulations promulgated
     thereunder ("ERISA")), that is or was maintained or contributed
     to by either of the Companies or any affiliate of either of the
     Companies or by any trade or business, whether or not
     incorporated, which together with either of the Companies would
     be deemed a "single employer" within the meaning of Section 4001
     of ERISA (an "ERISA Affiliate") within the last three years, for
     the benefit of any employee, former employee, consultant, officer
     or director of either of the Companies or any ERISA Affiliate (an
     "ERISA Plan") shall be delivered by Seller to Buyer on or before
     December 15, 1995 and shall constitute Section 4.24 of the
     Disclosure Schedule.  Neither Seller nor either of the Companies
     has any commitment, whether formal or informal and whether
     legally binding or not, to create any additional ERISA Plan which
     could have a Material Adverse Effect.

                    (b)  No ERISA Plan is a "multiemployer plan," as
     such term is defined in Section 3(37) of ERISA; no ERISA Plan is
     subject to Section 412 of the Code or Title IV of ERISA; each of
     the ERISA Plans is, and has always been, operated in all material
     respects in accordance with the requirements of all applicable
     laws, and all persons who participate in the operation of such
     ERISA Plans and all ERISA Plan "fiduciaries" (within the meaning
     of Section 3(21) of ERISA) have always acted substantially in
     accordance with the provisions of all applicable laws.  None of
     the ERISA Plans is intended to be "qualified" within the meaning
     of Section 401(a) of the Code; no ERISA Plan has an accumulated
     or waived funding deficiency within the meaning of Section 412 of
     the Code; within the past six years no "reportable event," as
     such term is defined in Section 4043(b) of ERISA, has occurred
     with respect to any ERISA Plan; and no condition exists that
     presents a material risk to either of the Companies or any ERISA
     Affiliate of incurring a liability to or on account of an ERISA
     Plan pursuant to Title IV of ERISA.

                    (c)  Full payment has been made, or will be made
     in accordance with Section 404(a)(6) of the Code, of all amounts
     which either of the Companies or any ERISA Affiliate is required
     to pay under the terms of each of the ERISA Plans as of the last
     day of the most recent plan year thereof ended prior to the date
     of this Agreement, and all such amounts properly accrued through
     the Closing Date with respect to the current plan year thereof
     have been paid by or on behalf of either of the Companies or are
     properly reflected in accordance with GAAP on the financial
     statements of the Companies.

                    (d)  No ERISA Plan provides benefits, including,
     without limitation, death or medical benefits (whether or not
     insured), with respect to current or former employees of either
     of the Companies or any ERISA Affiliate for periods extending
     beyond their retirement or other termination of service for which
     either of the Companies are or could be liable.

                    (e)  There has been no prohibited transaction
     (within the meaning of Section 406 of ERISA or Section 4975 of
     the Code) with respect to any ERISA Plan; neither of the
     Companies has incurred any material liability for any excise tax
     arising under Section 4972 or 4980B of the Code and no fact or
     event exists that could reasonably give rise to any such
     liability with respect to the filing of reports with respect to
     any ERISA Plan; there are no pending, threatened or anticipated
     claims (other than routine claims for benefits) by, on behalf of
     or against any of the ERISA Plans, or any trusts related thereto
     or any trustee or administrator thereof, and no material
     litigation or administrative or other proceeding (including,
     without limitation, any litigation or proceeding under Title IV
     of ERISA) has occurred or, to the best knowledge of Seller, is
     threatened involving any ERISA Plan or any trusts related thereto
     or any trustee or administrator thereof.

                    (f)  Except as set forth in Section 4.24 of the
     Disclosure Schedule or as expressly provided herein, the
     consummation of the transactions contemplated by this Agreement
     will not (i) entitle any current or former employee or officer of
     either of the Companies to severance pay, unemployment
     compensation or any other similar payment, (ii) accelerate the
     time of payment or vesting or increase the amount of compensation
     due any such employee or officer, (iii) result in any employment-
     related expenses or liabilities the full cost of which will not
     be paid by Seller or (iv) result in any prohibited transaction
     described in Section 406 of ERISA or Section 4975 of the Code for
     which an exemption is not available.

                    (g)  No employee, officer or director of either of
     the Companies will be entitled to receive any compensation,
     remuneration or financial benefit of any kind resulting from this
     Agreement or the transactions contemplated hereby, except as
     expressly provided herein.

                       REPRESENTATIONS AND WARRANTIES

               Buyer hereby represents and warrants to Seller as
     follows:

               5.1.  Corporate Organization.  Buyer and CUBSCO II are
     corporations duly organized, validly existing and in good
     standing under the laws of the State of Delaware.  CUBSCO I is a

     Boards of Directors of Buyer, CUBSCO I and CUBSCO II and the sole
     stockholder of CUBSCO I and CUBSCO II have taken all actions
     required by law, their respective charters, their respective By-
     Laws or otherwise to be taken by each of them to authorize the
     execution, delivery and performance of this Agreement and the
     Additional Buyer's Documents, and when fully executed and
     delivered, this Agreement and each of the Additional Buyer's
     Documents will constitute the valid and binding agreements of
     each of them, as the case may be, enforceable against each of
     them, as the case may be, in accordance with their respective
     terms.

               5.3.  SEC Filings.

                    (a)  Buyer has filed all forms, reports and
     documents (the "SEC Reports") required to be filed by it with the
     SEC since January 1, 1995.  The SEC Reports (i) were prepared in
     accordance with the requirements of the Securities Act and the
     Securities Exchange Act of 1934, as amended, as the case may be,
     and the rules and regulations thereunder, as amended
     (collectively, the "Rules and Regulations"), and (ii) did not at
     the time they were filed contain any untrue statement of a
     material fact or omit to state a material fact required to be
     stated therein or necessary in order to make the statements made
     therein, in the light of the circumstances under which they were
     made, not misleading.

                    (b)  Each of the consolidated financial statements
     (including, in each case, any notes thereto) contained in the SEC
     Reports was prepared in accordance with United States generally
     accepted accounting principles applied on a consistent basis
     throughout the periods indicated (except as may be indicated in
     the notes thereto), and each fairly presented the consolidated
     financial position, results of operations and changes in
     financial position of Buyer and its consolidated subsidiaries as
     of the respective dates thereof and for the respective periods
     indicated therein, except as otherwise noted therein (subject, in
     the case of unaudited statements, to normal and recurring year-
     end adjustments which were not and are not expected, individually
     or in the aggregate, to have a material adverse effect on Buyer).

               5.4.  Authorization and Issuance of SoftKey Shares. 
     The issuance of the SoftKey Shares has been duly authorized by
     Buyer, and upon delivery to Seller of the certificates therefor
     in accordance with Articles I and II hereof, the SoftKey Shares
     will be validly issued, fully paid and nonassessable, free and
     clear of all Liens and restrictions other than the restrictions
     imposed herein or by the Rules and Regulations.

               5.5.  Consents and Approvals; Non-Contravention. 
     Neither the execution, delivery or performance of this Agreement
     or any of the Additional Buyer's Documents by Buyer, CUBSCO I or
     CUBSCO II nor the consummation by each of them of the
     transactions contemplated hereby or thereby nor compliance by
     each of them with any of the provisions hereof or thereof will
     (a) violate any provision of the Restated Certificate of
     Incorporation, as amended, or By-Laws of Buyer or the
     Certificates of Incorporation of CUBSCO I or CUBSCO II, (b)
     except as may be required under the HSR Act, require any filing
     with, or permit, authorization, consent or approval of, any
     Governmental Entity, (c) violate any order, writ, injunction,
     decree, statute, rule or regulation applicable to Buyer or any of
     its properties or assets, (d) violate any contract to which Buyer
     is a party or by which it is bound or (e) violate any applicable
     law, statute, ordinance, rule or regulation, except in the case
     of clauses (c) and (d), for such violations which would not
     materially impair the ability of Buyer to perform its obligations
     hereunder or under any agreements entered into between Buyer and
     Seller, either alone or together with any other parties thereto,
     as of the date of this Agreement and which would not,
     individually or in the aggregate, have a material adverse effect
     on Buyer.

               5.6.  Litigation.  There is no claim, action, suit,
     inquiry, proceeding or investigation by or before any
     Governmental Entity pending or, to Buyer's knowledge, threatened
     against or involving Buyer which in any manner seeks injunctive
     or other non-monetary relief with respect to the transactions
     contemplated hereby or otherwise seeks to prevent, enjoin, alter
     or delay any transaction contemplated hereby, nor is there any
     basis for any such claim, action, suit, inquiry, proceeding or
     investigation.  Buyer is not subject to any order, writ,
     injunction or decree which, individually or in the aggregate, has
     or in the future would have a material adverse effect on the
     ability of Buyer to consummate the transactions contemplated
     hereby.

                                 ARTICLE VI

     to preserve intact the present business organization, keep
     available the services of their respective present officers and

     by Buyer during the period commencing at the Closing Date and
     ending six months after the Closing Date of any employee of
     either of the Companies immediately prior to the Closing;
     provided, however, that notwithstanding anything contained herein
     to the contrary, (a) Seller shall only be obligated to make such
     payments or reimbursements for Losses (i) to the extent that such
     Losses are incurred or sustained by Buyer pursuant to (A)
     provisions in Benefit Plans, agreements and arrangements in
     existence prior to the Closing (whether or not written), (B)
     requirements of or under applicable law, rules and regulations
     and (C) any other ordinary and customary practices and policies
     of Seller or either of the Companies as in effect immediately
     prior to the Closing, including such practices with respect to
     payments made pursuant to Clause (a)(i)(A) or (a)(i)(B) of this
     Section 6.6; and (b) in no event shall Seller be obligated to
     make such payments or reimbursements for any Losses in excess of
     $750,000 in the aggregate (except for any such Losses relating to
     the lawful termination during the periods specified above of any
     of the five individuals listed in Section 6.6 of the Disclosure
     Schedule, as to each of which individuals Seller shall be
     obligated to make payments or reimbursements hereunder for any
     such Losses in excess of ten weeks aggregate compensation for
     such individual).  "Losses" shall, include any loss, liability
     (including without limitation any liability for Taxes), damage,
     deficiency, cost and expense (including without limitation
     reasonable expenses of investigation and reasonable attorneys'
     fees).  Buyer agrees to provide to Seller, on or before the date
     which is 30 days after the Closing Date, a list setting forth the
     names of any such employees which it intends to terminate within
     the six-month period referenced in the preceding sentence,
     together with a description of any severance and termination
     costs and expenses expected to be incurred by Buyer and its
     Subsidiaries in accordance with the preceding sentence.

               6.7.  Noncompetition.

                    (a)  For a period of two years after the Closing
     (the "Noncompete Period"), neither Seller nor any of its
     affiliates shall, directly or indirectly, compete (as hereinafter
     defined) with Buyer without the prior written consent of Buyer,
     except that any financial interest or other relationship or
     arrangement with a third party existing on the date hereof shall
     not be deemed to "compete" with Buyer as provided herein.  For
     purposes of this Section 6.7(a), the term "compete" shall mean: 
     (i) directly or indirectly having a financial interest in any
     entity which has as a substantial part of its business the
     distribution of consumer software on CD-ROMS to retailers and
     end-users, except that Seller's beneficial ownership of not more
     than 20% of the securities of any such entity having total
     revenues of less than $20 million for the twelve-month period
     ending as of the end of the most recent fiscal quarter of each
     entity prior to Seller's initial acquisition of such ownership
     shall not constitute a violation of this Section 6.7(a); or (ii)
     directly or indirectly engaging or participating in, or
     conducting as an owner, manager or consultant of, or having a
     financial interest in, or aiding or assisting anyone else in the
     conduct of, any publisher of encyclopedia products for on-line
     (or other electronic) distribution or for production and
     distribution on CD-ROMS.

                    (b)  During the Noncompete Period, Seller shall
     not:  (i) hire, entice or in any other manner persuade or attempt
     to persuade any employee of either of the Companies (immediately
     prior to the Closing) or Buyer or any of their respective
     subsidiaries or affiliates to discontinue his or her relationship
     or violate any agreement with either of the Companies
     (immediately prior to the Closing) or Buyer or any of their
     respective subsidiaries or affiliates as employee, unless (A)
     Seller locates or identifies the employee for recruiting and
     employment through general recruiting efforts in the ordinary
     course of business and consistent with past practice or (B)
     contact between Seller and the employee, is initiated by that
     employee (without any prior direct or indirect intervention,
     prompting or notice by or from Seller, except as permitted in
     clause (A) of this Section 6.7(b)(i); or (ii) knowingly induce or
     knowingly attempt to induce any independent contractor, dealer,
     supplier client or customer of either of the Companies to
     discontinue his or her relationship or violate any agreement with
     either of the Companies as independent contractor, dealer,
     supplier, client or customer, respectively.

                    (c)  In the event the restrictions against
     engaging in competitive activity contained in Section 6.7(a)
     shall be determined by any court of competent jurisdiction to be
     unenforceable by reason of their extending for too great a period
     of time or over too great a geographical area or by reason of
     their being too extensive in any other respect, they shall be
     interpreted to extend only for the maximum period of time for
     which they may be enforceable, and over the maximum geographical
     area as to which they may be enforceable, and to the maximum
     extent in all other respects as to which they may be enforceable,
     all as determined by such court in such action.

               6.8.  CNI Recapitalization.  Prior to the Closing,
     Seller shall contribute to the capital of CNI each outstanding
     share of Series A Preferred Stock, Series B Preferred Stock and
     Series C Preferred Stock in a transaction constituting a
     recapitalization within the meaning of Section 368(a)(1)(E) of
     the Code.  As a result of the recapitalization transaction, no
     shares of Series A Preferred Stock, Series B Preferred Stock or
     Series C Preferred Stock will be outstanding at and as of the
     Closing.

               6.9.  Further Assurances.  From time to time after the
     Closing, Seller will use all reasonable efforts:  (a) to obtain
     any licenses, permits, waivers, consents, authorizations,
     qualifications and orders of Governmental Entities or other
     Persons or entities as Buyer shall reasonably request to enable
     the Companies to enjoy after the Closing the rights and benefits
     presently enjoyed by the Companies in the conduct of the NewMedia
     Business; (b) to transfer to the Companies, at the expense of
     Seller all rights in respect of the Assets or any leases,
     licenses or other contracts, commitments or agreements held by
     Seller or any of the Companies' respective affiliates used in or
     necessary for the conduct of the NewMedia Business in
     substantially the same manner as it is presently conducted
     (including without limitation those relating to the Assets) or
     otherwise use all reasonable efforts to provide benefits to the
     Companies or their respective assignees of such Assets or under
     such leases, licenses and other contracts, commitments and
     agreements which are at least as favorable as those in effect
     immediately prior to the Closing and (c) to provide Buyer with
     any additional information reasonably requested by Buyer to
     enable Buyer to comply with SEC reporting and other legal
     compliance requirements.

     hereto.  Any failure of any party to comply with any obligation,

     of, or estoppel with respect to, any subsequent or other failure. 
     No failure by any party to take any action against any breach of
     this Agreement or default by the other parties shall constitute a

     provided for herein, whether or not the transactions contemplated

               (b)  Holders of Transfer Restricted Securities.  A

     SECTION 3. REGISTRATION

               (a)  Shelf Registration.  The Company hereby agrees to:

               (i)  use its best efforts to file or cause to be filed
          the Registration Statement on or prior to the 90th day after
          the Closing Date (the "Shelf Filing Deadline"), which
          Registration Statement shall provide for resales of all
          Transfer Restricted Securities except (A) Transfer
          Restricted Securities held by transferees of any Holder who
          or which becomes a Holder after the Registration Statement
          is declared effective and (B) Transfer Restricted Securities
          held by the transferee of any Holder who or which holds less
          than $5,000,000 in principal amount of the Notes or the
          equivalent (on an "as exchanged" or "as converted" basis) in
          Preferred Shares or shares of Common Stock (such Transfer
          Restricted Securities being hereinafter referred to 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 Closing Date
          (the "Effectiveness Target Date").

     Subject to any notice by the Company in accordance with Section
     4(b) hereof of the existence of any fact or event of the kind
     described in Section 4(b)(iii)(D) hereof, the Company shall use
     all reasonable efforts to keep the 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 Statement conforms to the
     requirements of this Agreement, the Act and the policies, rules
     and regulations of the Commission as announced from time to time
     thereunder for a period of at least three years following the
     Closing Date. 

               (b)  Certificated Securities; Provision by Holders of
     Certain Information in Connection with the Registration
     Statement.  No Holder of Registrable 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 Statement and
     any Prospectus required by this Agreement, the Company shall:  

               (i)  subject to Section 4(b)(xv) hereof, use all
          reasonable efforts to keep the Registration Statement
          continuously effective and provide all requisite financial
          statements for the period specified in Section 3 of this
          Agreement; upon the occurrence of any event that would cause
          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 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
          representatives of the Company available for discussion of
          such document and other customary due diligence matters, and
          include such information in such document prior to the
          filing thereof as such selling Holders or underwriter(s), if
          any, reasonably may request;

               (vi)  make available at reasonable times for inspection
          by the selling Holders, any underwriter(s) participating in
          any disposition pursuant to the Registration Statement and
          any attorney or accountant retained by such selling Holders
          or any of the underwriter(s), all financial and other
          records, pertinent corporate documents and properties of the
          Company and cause the officers, directors and employees of
          the Company to supply all information reasonably requested
          by any such Holder, underwriters, attorney or accountant in
          connection with the Registration Statement subsequent to the
          filing thereof and prior to its effectiveness;

               (vii)  if requested by any selling Holders or the
          underwriters, if any, promptly incorporate in the
          Registration Statement or any Prospectus, pursuant to a
          supplement or post-effective amendment if necessary, such
          information as such selling Holders and underwriters, if
          any, may reasonably request to have included therein,
          including, without limitation, information relating to the
          "Plan of Distribution" of the Registrable Securities,
          information with respect to the principal amount or number
          of shares of Registrable Securities being sold to such
          underwriter(s), the purchase price being paid therefor and
          any other terms of the offering of the Registrable
          Securities to be sold in such offering and make all required
          filings of any such Prospectus supplement or post-effective
          amendment as soon as practicable after the Company is
          notified of the matters to be incorporated in such
          Prospectus supplement or post-effective amendment;

               (viii)  cause the Notes or Preferred Shares covered by
               the Registration Statement to be rated with the appropriate
          rating agencies, if so requested by the Holders of a
          majority in aggregate principal amount of Notes, in the case
          of the Notes, or a majority of the Preferred Shares, in the
          case of the Preferred Shares, or the underwriter(s) for any
          Underwritten Offering of such Notes or Preferred Shares, if
          any;

               (ix)  [Intentionally omitted]

               (x)  deliver to each selling Holder and each of the
          underwriter(s), if any, without charge, as many copies of
          each Prospectus (including each preliminary prospectus
          intended for public distribution) and any amendment or
          supplement thereto as such Persons reasonably may request;
          the Company hereby consents to the use of each Prospectus
          and any amendment or supplement thereto by each of the
          selling Holders and each of the underwriter(s), if any, in
          connection with the offering and the sale of the Transfer
          Restricted  Securities covered by any Prospectus or any
          amendment or supplement thereto;

               (xi)  enter into such customary agreements (including
          an underwriting agreement), and make such customary
          representations and warranties, and, subject to Section
          4(b)(xv) hereof, take all such other customary actions in
          connection therewith in order to expedite or facilitate the
          disposition of the Registrable Securities pursuant to the
          Registration Statement contemplated by this Agreement, all
          to such extent as may be requested by the Purchaser or by
          any Holder of Registrable Securities or underwriter in
          connection with any sale or resale pursuant to the
          Registration Statement contemplated by this Agreement; and
          whether or not an underwriting agreement is entered into and
          whether or not the registration is an Underwritten
          Registration, the Company shall:

                    (A)  furnish to the Purchaser, each selling Holder
               and each underwriter, if any (including any Broker-
               Dealer who may be deemed to be an underwriter),
               officers' certificates, legal opinions and comfort
               letters, in such substance and scope as they may
               request and as are customarily made by issuers to
               underwriters in primary underwritten offerings, upon
               the date of the effectiveness of the Registration
               Statement;

                    (B) set forth in full or incorporate by reference
               in the underwriting agreement, if any, indemnification
               provisions and procedures substantially in the form of
               those set forth in Section 6 hereof with respect to all
               parties required to be indemnified pursuant to said
               Section 6; and

                    (C)  deliver such other documents and certificates
               as may be reasonably requested by such parties to
               evidence compliance with clause (A) above and with any

               agreement or other agreement entered into by the
               Company pursuant to this clause (xi), if any.

               (xii)  prior to any public offering of Registrable 
          Securities, cooperate with the selling Holders, the
          underwriter(s), if any, and their respective counsel in
          connection with the registration and qualification of the
          Registrable Securities under the securities or Blue Sky laws
          of such jurisdictions as the selling Holders or
          underwriter(s) may request; and do any and all other acts or
          things necessary or advisable to enable the 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 clause (xii) above;

               (xv)  as soon as reasonably practicable after the
          occurrence of any fact or event of the kind described in
          clause (b)(iii)(D) above, prepare a supplement or post-
          effective amendment to the Registration Statement or related
          Prospectus or any 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
          Restricted Securities not later than the effective date of
          the Registration Statement and provide the Trustee under the
          Indenture with printed certificates for the Transfer
          Restricted Securities which are in a form eligible for
          deposit with The Depositary Trust Company;

               (xvii)  cooperate in any filings required to be made
          with the NASD and in the performance of any due diligence
          investigation by any underwriter (including any "qualified
          independent underwriter") that is required to be retained in
          accordance with 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 its security holders, as
          soon as practicable, a consolidated earnings statement
          meeting the requirements of Rule 158 (which need not be
          audited) for the twelve-month period (A) commencing at the
          end of any fiscal quarter in which Transfer Restricted 
          Securities are sold to underwriters in a firm commitment or
          best efforts Underwritten Offering or (B) if not sold to
          underwriters in such an offering, beginning with the first
          month of the Company's first fiscal quarter, as applicable,
          commencing after the effective date of the Registration
          Statement;

               (xix)  cause the Indenture to be qualified under the
          TIA not later than the effective date of the Registration
          Statement, and, in connection therewith:  cooperate with the
          Trustee and the Holders of Notes to effect such changes to
          the Indenture as may be required for such Indenture to be so
          qualified in accordance with the terms of the TIA; and
          execute and use all reasonable efforts to cause the Trustee
          to execute, all documents that may be required to effect
          such changes and all other forms and documents required to
          be filed with the 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 issued by the Company
          are then listed if requested by the Holders of a majority in
          aggregate principal amount of Notes, the Holders of a
          majority of shares of the Preferred Shares, or the managing
          underwriter(s), if any; and

               (xxi)  provide promptly to each Holder upon request any
          document filed with the Commission pursuant to the
          requirements of Section 13 and Section 15 of the Exchange
          Act.

             Each Holder agrees by acquisition of a Transfer
     Restricted Security that, upon receipt of any notice from the
     Company of the existence of any fact or event of the kind
     described in Section 4(b)(iii)(D) hereof, such Holder will
     forthwith discontinue disposition of Registrable Securities
     pursuant to the applicable Registration Statement until such
     Holder's receipt of the 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 of the
     Registration Statement set forth in Section 3 hereof shall be
     extended by the number of days during the period from and
     including the date of the giving of such notice pursuant to
     Section 4(b)(iii)(D) hereof to and including the date when each
     selling Holder covered by the Registration Statement shall have
     received the copies of the supplemented or amended prospectus
     contemplated by Section 4(b)(xv) hereof or shall have received
     the 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 purposes of the
     Securities Act or Accounting Series 130 and 135 of the Commission
     and (B) (i) the Company has 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.

     SECTION 5. REGISTRATION EXPENSES

             (a) All expenses incident to the Company's performance of
     or compliance with this Agreement will be borne by the Company
     regardless of whether the Registration Statement becomes
     effective, including without limitation:  (i) all registration
     and filing fees and expenses (including, if applicable, the fees
     and expenses of any "qualified independent underwriter" and its
     counsel that may be required by the rules and regulations of the
     NASD); (ii) all fees and expenses associated with compliance with
     federal securities and state Blue Sky or securities laws; (iii)
     all expenses of printing (including printing of any certificates
     evidencing the Notes and Preferred Shares and printing of
     Prospectuses), messenger and delivery services and telephone
     charges; (iv) all fees and disbursements of counsel for the
     Company and, as provided for in Section 5(b) below, the Holders
     of Registrable Securities; (v) all application and filing fees in
     connection with listing any securities on a national securities
     exchange or automated quotation system pursuant to the
     requirements hereof; and (vi) all fees and disbursements of
     independent certified public accountants of the Company
     (including the expenses of any special audit and comfort letters
     required by or incident to such performance).

             The Company will, in any event, bear its own internal
     expenses (including, without limitation, all salaries and
     expenses of its officers and employees performing legal or
     accounting duties), the expenses of any annual audit and the fees
     and expenses of any Person, including special experts, retained
     by the Company.

             (b)  In connection with the Registration Statement
     required by this Agreement, the Company agrees to reimburse the
     Purchaser and the Holders of Transfer Restricted  Securities
     being registered pursuant to the Registration Statement for the
     reasonable fees and disbursements of not more than one counsel,
     who shall be Sidley & Austin or such other counsel as may be
     chosen by the Holders of a majority in principal amount or a
     majority of the shares of the Registrable Securities for whose
     benefit the Registration Statement is being prepared.

     SECTION 6. INDEMNIFICATION

             (a)  The Company agrees to indemnify and hold harmless
     (i)each Holder and (ii) each person, if any, who controls (within
     the meaning of Section 15 of the Act or Section 20 of the
     Exchange Act) any Holder (any of the persons referred to in this
     clause (ii) being hereinafter referred to as a "controlling
     person") and (iii) the respective officers, directors, partners,
     employees, representatives and agents of any Holder or any
     controlling person (any person referred to in clause (i), (ii) or
     (iii) may hereinafter be referred to as an "Indemnified Holder"),
     to the fullest extent lawful, from and against any and all
     losses, claims, damages, liabilities, judgments, costs and
     expenses ("Losses") (including, without limitation and as
     incurred, reimbursement of all costs of investigating, preparing,
     pursuing or defending any claim or action, or any investigation
     or proceeding by any governmental agency or body, commenced or
     threatened, including the reasonable 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 writing by
     hand-delivery, first-class mail (registered or certified, return
     receipt requested), telex, telecopier or courier guaranteeing 
     overnight deliver;

                             STANDSTILL AGREEMENT

                    STANDSTILL AGREEMENT (this "Agreement") dated
          as of November 30, 1995 by and between Tribune Company, a
          Delaware corporation ("Stockholder"), and SoftKey
          International Inc., a Delaware corporation ("Issuer").

                    On November 30, 1995, Stockholder and Issuer:
          (a) executed and delivered a Securities Purchase
          Agreement (the "Purchase Agreement") providing for the
          issuance and sale by Issuer, and the purchase by
          Stockholder, of $150,000,000 principal amount of 5-1/2%
          Senior Convertible/Exchangeable Notes due 2000 (the
          "Notes"), which may be (i) exchanged for Issuer's 5-1/2%
          Series C Convertible Preferred Stock (the "Preferred
          Stock") which may be converted into shares of common
          stock, par value $.01 per share, of Issuer (the "Common
          Stock"), or (ii) converted directly into shares of Common
          Stock; and (b) together with certain wholly owned
          subsidiaries, executed and delivered an Agreement and
          Plan of Merger (the "Merger Agreement") providing for two
          separate reverse subsidiary mergers of wholly owned
          subsidiaries of Issuer with and into wholly owned
          subsidiaries of Stockholder in which Issuer will issue to
          Stockholder, and Stockholder will receive from Issuer,
          shares of Common Stock.

                    This Agreement is the Standstill Agreement
          referenced in the Merger Agreement and sets forth certain
          terms and conditions upon which the Issuer will issue and
          deliver to Stockholder, and Stockholder (a) will receive
          and accept from Issuer, (b) owns and holds, and (c) will
          own and hold, the shares of Common Stock acquired by
          Stockholder, or any shares of Common Stock which
          Stockholder has the right to acquire, pursuant to the
          Purchase Agreement and the Merger Agreement (the
          "Shares").

                    In consideration of the mutual agreements
          contained in the Purchase Agreement, the Merger Agreement
          and herein, and for other good and valuable
          consideration, the sufficiency and receipt of which are
          hereby acknowledged, the parties agree as follows:

                    1.  Stockholder's Representations and
          Warranties.  Stockholder represents and warrants to
          Issuer as follows:

                         (a)  Stockholder is a corporation duly
          organized, validly existing and in good standing under
          the laws of the State of Delaware;

                         (b)  Stockholder (i) has the full power
          and authority to execute and deliver this Agreement,
          perform its obligations hereunder and consummate the
          transactions contemplated hereby and (ii) has taken all
          necessary action to authorize the execution, delivery and
          performance by Stockholder of this Agreement;

                         (c)  this Agreement has been duly and
          validly authorized, executed and delivered by Stockholder
          and constitutes the valid and binding obligation of
          Stockholder, enforceable in accordance with its terms;

                         (d)  Stockholder (or any direct or
          indirect subsidiary of Stockholder and all persons
          controlling, controlled by or under common control with
          Stockholder ("Affiliates"), as the case may be), is, or
          upon issuance to it by Issuer will be, the sole
          beneficial holder of all the Shares, and Stockholder and
          Affiliates have not granted or permitted to exist any
          liens, claims, options, proxies, voting agreements,
          charges or encumbrances of whatever nature affecting the
          Shares;

                         (e)  the Notes and Shares owned and held
          by Stockholder and Affiliates as of the date hereof
          constitute all of the securities of Issuer owned by
          Stockholder and Affiliates;

                         (f)  Stockholder (or Affiliates, as the
          case may be) is not acquiring the Notes and Shares owned
          and held by Stockholder and is not acquiring the Shares
          which may be acquired after the date hereof with the
          intent or objective of obtaining control of the business,
          operations or affairs of Issuer; and

                         (g)  except as set forth in the Purchase
          Agreement and the Merger Agreement, neither the
          Stockholder nor any Affiliate has outstanding any option,
          warrant or other right to acquire, directly or
          indirectly, any securities of Issuer or any securities
          which are convertible into or exchangeable or exercisable
          for any securities of the Issuer, nor is the Stockholder
          or any Affiliate subject to any agreement (whether
          written or in the nature of an informal understanding or
          arrangement) which allows or obligates the Stockholder or
          any such Affiliate to vote or acquire any securities of

                    2.  Issuer's Representations and Warranties.   
          Issuer represents and warrants to Stockholder as follows:

                         (a)  Issuer is a corporation duly
          organized, validly existing and in good standing under
          the laws of the State of Delaware;

                         (b)  Issuer (i) has the full power and
          authority to execute and deliver this Agreement, perform
          its obligations hereunder and consummate the transactions

          action to authorize the execution, delivery and
          performance by Issuer of this Agreement; and

                         (c)  this Agreement has been duly and
          validly authorized, executed and delivered by Issuer and
          constitutes the valid and binding obligation of Issuer,
          enforceable in accordance with its terms.

                    3.  Covenants of Stockholder.  Stockholder
          covenants with Issuer that, without the consent of
          Issuer, for a period commencing on the date hereof and
          continuing through the fifth anniversary of the date
          hereof Stockholder and Affiliates, singly or as part of a
          group, directly or indirectly, through one or more
          intermediaries or otherwise, will not:

                         (a)  purchase, acquire or own, or offer,
          propose or agree to purchase, acquire or own, directly or
          indirectly, any securities of Issuer which are entitled
          to vote generally in the election of directors (other
          than upon occurrence of a contingency) ("Voting
          Securities"), any option, warrant or other right to
          acquire, directly or indirectly, any Voting Securities or
          any securities which are convertible into or exchangeable
          or exercisable for Voting Securities, if, immediately
          after such purchase or acquisition, Stockholder and
          Affiliates would beneficially own, in the aggregate,
          Voting Securities representing an amount (the "Threshold
          Amount") which exceeds the greater of 20% of Issuer's
          outstanding Voting Securities or such percentage of the
          Issuer's outstanding Voting Securities which the sum of
          the Shares issued in connection with the Merger Agreement
          and the Shares issuable upon the conversion of the Notes
          issued in connection with the Purchase Agreement (taking
          into account any Voting Securities into which such Notes
          (or any Preferred Stock for which such Notes are
          exchanged) may from time to time be convertible as a
          result of application of the anti-dilution provisions
          applicable to the Notes or the Preferred Stock) would
          constitute on a fully diluted basis on the date of the
          later of the closings of the transactions contemplated by
          the Merger Agreement and the Purchase Agreement;
          provided, however, that notwithstanding anything to the
          contrary contained herein, the foregoing restriction
          shall not be deemed to be violated or applicable if
          Stockholder is not otherwise in breach of this Agreement
          and (i) the percentage of the outstanding Voting
          Securities beneficially owned, in the aggregate, by
          Stockholder and Affiliates is increased as a result of a
          recapitalization of Issuer, a repurchase of securities by
          Issuer or any other action taken solely by Issuer, (ii) a
          benefit plan maintained for employees of Stockholder and
          Affiliates acquires up to 1% (in the aggregate) of the
          outstanding Common Stock solely for purposes of
          investment, or (iii) Issuer breaches its obligation under
          Section 4(b) hereof; and provided, further, that so long
          as Stockholder is not otherwise in breach of this
          Agreement, (i) if a third party (which term for purposes
          of this Agreement shall include any group as defined in
          Section 13(d)(3) of the Securities Exchange Act of 1934,
          as amended) makes a tender or exchange offer which, if
          consummated, would result in such third party owning at
          least a majority of the Voting Securities and Issuer's
          Board of Directors does not oppose such tender or
          exchange offer at the time at which it is required by
          applicable securities laws to make a recommendation
          regarding such tender or exchange offer to Issuer's
          stockholders, then Stockholder may make and consummate a
          tender or exchange offer for a number of Voting
          Securities equal to or greater than the number of Voting
          Securities which such third party seeks to purchase
          pursuant to such tender or exchange offer, (ii) if a
          third party acquires beneficial ownership of at least 30%
          of the outstanding Voting Securities, and Stockholder is
          prohibited by the terms of this Agreement from acquiring
          more than 30% of the outstanding Voting Securities, then
          Stockholder may purchase up to the same number of Voting
          Securities as such third party or may make and consummate
          a tender or exchange offer for all outstanding Voting
          Securities, and (iii) if Issuer's Board of Directors
          approves a definitive written agreement with respect to a
          business combination or other extraordinary transaction
          involving Issuer as a result of which more than 50% of
          the assets of Issuer would be transferred or a Change of
          Control (as defined below) would occur, then Stockholder
          may make and consummate a tender or exchange offer for
          all outstanding Voting Securities, and if Stockholder is
          permitted to make and consummate a tender or exchange
          offer pursuant hereto, none of the restrictions contained
          in this Section 3 (with the exception of Section 3(f) and
          the application of Section 3(g) to Section 3(f)) shall
          apply to Stockholder's activities with regard to any
          stockholder vote or proposal in connection therewith or
          in connection with any alternative transaction or action
          proposed in response thereto; "Change of Control" shall
          mean any transaction as a result of which (i) the owners
          of a majority of the Voting Securities of Issuer
          immediately prior to consummation of the transaction will
          not continue to own upon completion of the transaction
          (A) a majority of the Voting Securities of Issuer or (B)
          a majority of the Voting Securities of any other person
          into or for the securities of which the Voting Securities
          of Issuer will be converted or exchanged as a result of
          the transaction or (ii) as a result of which any third
          party is entitled to elect a majority of the members of
          the Board of Directors of Issuer;

                         (b)  solicit, or encourage any other
          person to solicit, "proxies" or become a "participant" or
          otherwise engage in any "solicitation" (as such terms are
          defined or used in Regulation 14A under the Securities
          Exchange Act of 1934, as amended (the "Exchange Act")) in
          opposition to a recommendation of a majority of the
          directors of Issuer with respect to any matter; seek to
          advise or influence any person (within the meaning of
          Section 13(d)(3) of the Exchange Act) with respect to the
          voting of any securities of the Issuer; or execute any
          written consent in lieu of a meeting of holders of
          securities of Issuer or any class thereof; provided,
          however, that if Stockholder is entitled to elect
          directors of Issuer pursuant to Section 3.3 of the
          Certificate of Designation of the Preferred Stock (the
          "Certificate of Designation"), nothing in this Section
          3(b) shall be construed to prohibit Stockholder from
          soliciting proxies for the election of such directors
          from the holders of Defaulted Parity Stock (as defined in
          the Certificate of Designation);

                         (c)  initiate, propose or otherwise
          solicit stockholders for the approval of one or more
          stockholder proposals with respect to Issuer, as
          described in Rule 14a-8 under the Exchange Act;

                         (d)  acquire control of Issuer or directly
          or indirectly participate in or encourage the formation
          of any "group" (within the meaning of Section 13(d)(3) of
          the Exchange Act) owning or seeking to acquire beneficial
          ownership of securities of the Issuer or affect control
          of Issuer;

                         (e)  otherwise act, directly or
          indirectly, alone or in concert with others, to seek to
          control or influence in any manner the management,
          business, operations, board of directors, policies or
          affairs of Issuer, or propose or seek to effect any form
          of business combination transaction with Issuer or any
          affiliate thereof or any restructuring, recapitalization
          or other similar transaction with respect to Issuer;

                         (f)  deposit any of the Shares into a
          voting trust, or subject any of the Shares to any
          agreement or arrangement with respect to the voting of
          the Shares or any agreement having similar effect to any
          of the foregoing in this Section 3(f); or

                         (g)  (i) encourage any person, firm,
          corporation, group or other entity to engage in any of
          the actions covered by clauses (a) through (e) of this
          Section 3 or make any public arrangement (or make other
          communication with or to Issuer or otherwise which, in
          the opinion of counsel to Issuer, would require public
          announcement) with respect to any matter set forth in
          clause (a) through (f) of this Section 3;

          provided, however, that actions taken by any
          representative of Stockholder on the Board of Directors
          of Issuer, acting solely in his or her capacity as such a
          director, shall not violate this Section 3.  Stockholder
          further covenants to cause the termination or resignation
          of any director being removed from the Board of Directors
          of Issuer in accordance with Section 4(b) hereof.

                    4.  Covenants of Issuer.  Issuer covenants with
          Stockholder that:

                         (a)  prior to (i) the closing of the
          transactions contemplated by the Purchase Agreement and
          the Merger Agreement, whichever occurs earlier (the
          "First Closing"), or, if later, (ii) any other event or
          transaction which would result in Stockholder
          beneficially owning 15% or more of the outstanding Voting
          Securities, the Board of Directors of Issuer shall
          approve any and all agreements, events or transactions
          for purposes of Section 203 of the Delaware General
          Corporation Law ("Section 203") in order that the
          restrictions contained in Section 203 shall not be
          applicable to Stockholder and Affiliates;

                         (b)  Immediately after the First Closing,
          and so long as Stockholder shall not be in breach of any
          of its obligations hereunder, the Board of Directors of
          Issuer shall take all necessary actions to increase the
          size of such Board by one and to fill the vacancy created
          thereby with an individual designated in writing by
          Stockholder and reasonably acceptable to Issuer, and, if
          at any time Issuer's Board of Directors shall consist of
          11 or more members and the transactions contemplated by
          both the Purchase Agreement and the Merger Agreement
          shall have been consummated, then Issuer's Board of
          Directors shall take all necessary actions to increase
          further the size of the Board by one and to fill the
          additional vacancy created thereby with a second
          individual designated in writing by Stockholder and
          reasonably acceptable to Issuer, and Issuer shall
          thereafter take such action as necessary or appropriate
          to include such individuals among Issuer's nominees for
          director, shall recommend to its stockholders a vote in
          favor of such individuals at any annual or special
          meeting of stockholders called to vote upon the election
          or removal of any directors, and shall cause all shares
          of capital stock of Issuer over which Issuer exercises
          direct or indirect voting power to be voted in favor of
          the election of the individuals designated in writing
          hereunder by Stockholder; provided, however, that at such
          time as Stockholder has the right to designate two
          directors and Stockholder beneficially owns fewer than
          5,000,000 but at least the lesser of (i) 2,800,000 shares
          of Common Stock (including, for purposes of this
          calculation, the number of shares of Common Stock into
          which the Notes and Preferred Stock beneficially owned by
          Stockholder are then convertible) and (ii) 75% of the sum
          of any Shares issued in connection with the Merger
          Agreement and the Shares issuable upon the conversion of
          any Notes issued in connection with the Purchase
          Agreement (taking into account any Voting Securities into
          which such Notes (or any Preferred Stock for which such
          Notes are exchanged) may from time to time be convertible
          as a result of the application of the anti-dilution
          provisions applicable to the Notes or the Preferred
          Stock) (the lesser of the foregoing clauses (i) and (ii)
          being referred to herein as the "Lesser Amount"), then
          one of Stockholder's nominees shall be removed from
          Issuer's Board of Directors and Issuer's obligations
          under this Section 4(b) shall only apply in respect of
          the election of one nominee of Stockholder, and at such
          time as Stockholder owns fewer shares of Common Stock
          than the Lesser Amount, Stockholder's remaining or, as
          the case may be, sole nominee shall be removed from
          Issuer's Board of Directors and Issuer shall be relieved
          of its obligations under this Section 4(b); and

                         (c)  Issuer will not, for so long as this
          Agreement is effective, enter into or adopt any plans,
          agreements, arrangements or understandings which have the
          effect of materially impeding, preventing or prohibiting
          Stockholder from beneficially owning, in the aggregate,
          the Threshold Amount.

                    5.  Specific Performance.  Issuer and
          Stockholder each acknowledge and agree that in the event
          of any breach of this Agreement, the non-breaching party
          would be irreparably harmed and could not be made whole
          by monetary damages.  It is accordingly agreed that
          Issuer and Stockholder, in addition to any other remedy
          to which they may be entitled at law or in equity, shall
          be entitled to compel specific performance of this
          Agreement in any action instituted in the federal courts
          located in the State of Delaware, or, in the event said
          courts would not have jurisdiction for such action, in
          any court of the United States or any state having
          subject matter jurisdiction.  Issuer and Stockholder each
          consent to personal jurisdiction in any such action
          brought in the federal courts located in the State of
          Delaware and to service of process upon it in the manner
          set forth in Section 7(g) hereof and addressed to the
          General Counsel of the recipient at the address set forth
          in Section 7(g).

                    6.  Expenses.  All fees and expenses incurred
          by Stockholder will be borne by Stockholder, and all fees
          and expenses incurred by Issuer in connection with this
          Agreement will be borne by Issuer.

                    7.  Miscellaneous.

                         (a)  This Agreement, together with the
          Purchase Agreement, the Merger Agreement and the other
          agreements contemplated hereby and thereby, constitute
          the entire agreement, and supersede all prior agreements
          and understandings, whether oral or written, among the
          parties hereto, with respect to the subject matter
          hereof.  This Agreement may not be amended orally, but
          only by an instrument in writing signed by each of the
          parties to this Agreement.

                         (b)  This Agreement shall inure to the
          benefit of and be binding upon the parties hereto and
          their heirs, legal representatives, successors and
          assigns.

                         (c)  Section headings contained in this
          Agreement are for reference purposes only and shall not
          affect the meaning or interpretation of this Agreement.

                         (d)  All representations, warranties and
          covenants shall survive the execution and delivery
          hereof.

                         (e)  This Agreement may be executed in any
          number of counterparts, each of which shall, when
          executed, be deemed to be an original and all of which
          shall be deemed to be one and the same instrument.

                         (f)  This Agreement shall be governed by
          and construed and enforced in accordance with the laws of
          the State of Delaware, without reference to the conflict
          of laws principles thereof.

                         (g)  All notices and other communications
          under this Agreement shall be in writing and delivery
          thereof shall be deemed to have been made either (i) if
          mailed, when received, or (ii) when transmitted by hand
          delivery, telegram, telex, FedEx or other overnight
          courier service, telecopier or facsimile transmission (in
          either case, if confirmed), to the party entitled to
          receive the same at the address or facsimile number set
          forth in the Merger Agreement (as the same may be amended
          or modified in accordance with the terms thereof).

                         (h)  Any waiver by any party of a breach
          of any provision of this Agreement shall not operate as
          or be construed to be a waiver of any other breach of
          such provision or of any breach of any other provision of
          this Agreement.  The failure of a party to insist upon
          strict adherence to any term of this Agreement on one or

                                         Dated: [             ](1)

          FOR VALUE RECEIVED, PIANO INTERNATIONAL INC., a Delaware

          order of TOWER COMPANY, a Delaware corporation
          ("Lender"), the principal sum of [     ] million dollars
          ($[     ]) by deposit to [BANK], account no. [    ], in
          lawful money of the United States of America in
          immediately available funds, or in such other manner as
          is provided for herein or as Lender may designate in
          writing, on or before [          ](2) (the "Maturity
          Date"), with interest on the unpaid balance of such
          principal amount at the rate of 6-1/2% per annum from the
          date hereof until such principal amount is paid in full. 
          Subject to compliance with any applicable provisions of
          the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
          as amended (the "HSR Act"), Buyer may pay amounts due
          under this Note at maturity by delivering to Lender, on
          the Maturity Date, the number of shares, rounded up to
          the nearest whole share, of common stock, par value $.01
          per share, of Borrower ("Common Stock") obtained by
          dividing the unpaid principal balance plus accrued
          interest thereon to the Maturity Date by the volume-
          weighted average of the closing prices for Common Stock
          as quoted over the Nasdaq National Market for the ten
          full trading days preceding the Maturity Date.   

          Borrower may prepay this Note in whole or in part without
          premium or penalty:  (a) at any time in immediately
          available funds in an amount equal to the principal
          amount of the Note to be prepaid plus accrued interest on
          such principal amount to the date on which such
          prepayment is made or (b) subject to compliance with any
          applicable provisions of the HSR Act, by delivering to
          Lender, during the twenty-day period commencing on the
          three-month, six-month or nine-month anniversary of the
          date of issuance of this Note set forth above, the number
          of shares, rounded up to the nearest whole share, of
          Common Stock obtained by dividing the principal amount to
          be prepaid plus accrued interest thereon to the date on
          which the prepayment is made by the volume-weighted
          average of the closing prices for Common Stock as quoted

          ___________________                    
          1    Closing Date under the Merger Agreement.

          2    The first anniversary of the Closing Date under the
               Merger Agreement.


          over the Nasdaq National Market for the ten full trading
          days preceding any such date on which such prepayment is
          made; provided, however, that Borrower must notify Lender
          of any such prepayment at least eleven days prior to the
          date on which such prepayment is to be made.  

          Borrower represents that, upon delivery of certificates
          for shares of Common Stock in accordance with the terms
          and provisions of this Note, such shares of Common Stock
          will be validly issued, fully paid and nonassessable.  

          Lender represents that any shares of Common Stock which
          may be issued and delivered to it hereunder will be
          acquired for its own account, for investment for an
          indefinite period of time, not as nominee or agent for
          any other person, firm or corporation and not for
          distribution or resale to others; provided, however, that
          Borrower and Lender hereby acknowledge that Lender may
          dispose of some or all of the shares of Common Stock so
          acquired pursuant to an effective registration statement
          under the Securities Act of 1933, as amended (the
          "Securities Act"), or in a transaction exempt from
          registration under the Securities Act.  Lender agrees
          that it will not sell or otherwise transfer any shares of
          Common Stock so acquired unless such shares are
          registered under the Securities Act or unless an
          exemption from such registration is available.

          Interest shall be computed hereunder based on actual days
          elapsed.

          In no event shall the amount of interest due or payable
          hereunder exceed the maximum rate of interest allowed by
          applicable law, and in the event any payment is made
          which exceeds such maximum lawful rate, then the amount
          of such excess sum shall be credited as a payment of
          principal.  It is the express intent hereof that the
          Borrower shall not pay and the Lender shall not receive,
          directly or indirectly, interest in excess of what may
          lawfully be paid by Borrower under applicable law.

          This Note may not be assigned without the prior written
          consent of Lender.

          This Note may not be changed, amended or modified except
          by agreement in writing signed by Borrower and Lender.

          Borrower hereby waives demand for payment, presentment
          for payment, protest and notice of any kind whatsoever.

          THIS NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE
          GOVERNED BY THE LAWS OF THE STATE OF DELAWARE (WITHOUT
          GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING TO
          CONFLICTS OF LAW).

                     3.3.  Non-Federal Separate Taxes for Pre-Closing
     Periods and Straddle Periods.  To the extent that a liability for
     Non-Federal Separate Taxes arises other than as a result of a
     Redetermination (as defined in Section 4, below) and such liabil-
     ity for Non-Federal Separate Taxes (when aggregated with all
     other such liabilities paid or payable after the CNI
     Deconsolidation Date or CLC Deconsolidation Date on a cumulative
     basis, excluding such liabilities that arise as a result of a
     Redetermination) exceeds $50,000, Seller shall (as directed by
     Buyer or the Companies) (i) pay to the appropriate Tax Authori-
     ties or (ii) reimburse CNI and/or CLC for all of the Non-Federal
     Separate Taxes, if any, with respect to the assets, earnings, and
     operations of CNI Group and CLC Group, due and payable for all

     Federal Income Taxes for Pre-Closing Periods, which are governed
     by Section 3.1 above), if any, due and payable for all Pre-
     Closing Periods and that portion of any Straddle Periods up to
     and including the CNI Deconsolidation Date and CLC
     Deconsolidation Date.

          Section 4.  Redetermination.  In the event of any redetermi-
     nation of any item of income, gain, loss, deduction or credit of
     any member of the Affiliated Group or a Combined Group for any
     Pre-Closing Period or Straddle Period as a result of a final
     assessment, settlement, or compromise with any Tax Authority
     (including any amended Tax return or claim for refund filed by
     Seller pursuant to Section 6.1 or the relevant Subsidiary Group
     pursuant to Section 6.2) or a judicial decision that has become
     final (a "Redetermination"), Seller and Buyer shall recompute the
     Tax due on the relevant Tax Return for such Pre-Closing Period or
     Straddle Period (and any other Pre-Closing Periods which are
     affected thereby) to take into account such Redetermination.  If
     a Redetermination results in an increase in the liability for
     Taxes of the Affiliated Group or Combined Group for any Pre-
     Closing Period or Straddle Period and such increase is attribut-
     able to an item of income, gain, loss, deduction or credit of the
     CNI Group or CLC Group for a Pre-Closing Period or Straddle
     Period of the Affiliated Group during which the CNI Group or CLC
     Group was a member of the Affiliated Group or Combined Group, as
     directed by CNI and CLC, Seller shall (i) pay to the appropriate
     Tax Authorities or (ii) reimburse CNI and/or CLC for the amount
     of such increased liability for Taxes.

     and hold Buyer, CNI, CLC, and their affiliates harmless from and
     against any loss, cost, expense (including reasonable attorneys
     fees and costs) and any and all liabilities imposed on or in-
     curred by Buyer, CNI, CLC, and/or any of their affiliates in
     respect of any liability for any Taxes (including any liability
     for Federal Taxes imposed pursuant to Treasury Regulation
     SECTION 1.1502-6 or similar provision under state, local or foreign
     law) for any Pre-Closing Period and that portion of any Straddle
     Period up to and including the later of the CNI Deconsolidation
     Date and the CLC Deconsolidation Date; provided, however, that
     with respect to indemnification for any liability arising out of
     Non-Federal Separate Taxes, Seller shall indemnify, defend and
     hold Buyer, CNI, CLC, and their affiliates harmless from and
     against any loss, cost, expense (including reasonable attorneys
     fees and costs) and any and all liabilities imposed on or in-
     curred by Buyer, CNI, CLC, and/or any of their affiliates in
     respect of any liability for any Non-Federal Separate Taxes for
     any Pre-Closing Period and that portion of any Straddle Period up
     to and including the later of the CNI Deconsolidation Date and
     the CLC Deconsolidation Date, only if (i) such liability for Non-
     Federal Separate Taxes arises as a result of a Redetermination or
     (ii) such liability for Non-Federal Separate Taxes exceeds (when
     aggregated with all other such liabilities paid or payable after
     the CNI Deconsolidation Date or CLC Deconsolidation Date on a
     cumulative basis, excluding such liabilities that arise as a
     result of a Redetermination) $50,000 and arises in any manner
     other than as a result of a Redetermination. 

                     5.2.  Calculation of Indemnity.  In the case of
     any liability asserted against a party entitled to be indemnified
     (an "Indemnitee") pursuant to Section 5.1. hereof, Seller (the
     "Indemnitor"), shall pay to the Indemnitee an amount (the "Indem-
     nity Amount") that, after subtraction of all Taxes payable by
     such Indemnitee as a result of the receipt or accrual of such
     amount, shall be equal to the amount by which the Taxes payable
     by such Indemnitee, taking such liability into account, exceed in
     the aggregate the Taxes that would have been required to be paid
     by such Indemnitee had such liability never occurred.

          Section 6.  Audits, Disputes, Etc.

                     6.1.  Federal Taxes and Non-Federal Combined
     Taxes for Pre-Closing Periods and Straddle Periods.  Seller shall
     have the exclusive right to control and represent the interests
     of all parties hereto in any Audit, to initiate any claim for
     refund, to contest, resolve and defend against any assessment,
     notice of deficiency, or other adjustment or proposed adjustment
     of Federal Taxes or Non-Federal Combined Taxes (including the
     right to agree to any assessment, deficiency, or settlement of
     any of the foregoing items) relating to any Federal Tax Return or
     Non-Federal Combined Tax Return of Seller, CNI, or CLC filed for
     any Pre-Closing Period or Straddle Period during which CNI or CLC
     was a member of the Affiliated Group or Combined Group, as the
     case may be.  In the event CNI or CLC wants to contest an item or
     matter relating to CNI or CLC which item would adversely affect
     the liability of CNI or CLC for Federal Taxes or Non-Federal
     Combined Taxes for a Post-Closing Period or portion of a Straddle
     Period ending after the CNI Deconsolidation Date or CLC
     Deconsolidation Date (a "Subsidiary Matter"), CNI or CLC, as the
     case may be, may request Seller's written consent, which consent
     shall not be unreasonably withheld, that CNI or CLC be entitled
     to contest, resolve and defend against any such Subsidiary
     Matter, at CNI's or CLC's expense; provided, however, that
     Seller's consent shall not be considered unreasonably withheld
     if, among other reasons, Seller determines that (i) CNI or CLC
     will assert a position with respect to such Subsidiary Matter
     that is contrary to a position that has been asserted by a member
     of the Affiliated Group with respect to a similar Federal Tax
     matter or Non-Federal Combined Tax matter or (ii) provision of
     such consent could result in an unreasonable delay in Seller's
     resolution of any Audit that would result in a material cost to
     Seller.  Seller shall have the exclusive right to file any
     amended Federal Tax Return or amended Non-Federal Combined Tax
     Return relating to any Federal Tax Return or Non-Federal Combined
     Tax Return, as the case may be, filed for any Pre-Closing Period
     during which the CNI Group, CLC Group or a Subsidiary Combined
     Group was a member of the Affiliated Group or Combined Group, as
     the case may be; provided, however, that Seller shall not file
     any such amended Federal Tax Return that contains a Subsidiary
     Matter without the prior written consent of CNI or CLC, as the
     case may be, which consent shall not be unreasonably withheld. 
     Upon request, Buyer, CNI, CLC, and Seller will execute and
     deliver to Seller or Buyer, as the case may be, such powers of
     attorney as may be reasonably necessary to authorize Seller,
     Buyer, CNI, or CLC to extend statutes of limitations, receive
     refunds, and take such other actions that Seller, Buyer, CNI, or
     CLC may reasonably consider to be necessary to contest any Audit
     pursuant to this Section 6.1.

               6.2.  Non-Federal Separate Taxes for Pre-Closing
     Periods and Straddle Periods.  CNI and CLC shall have the exclu-
     sive right to control, conduct and to represent the interests of
     all parties hereto in any Audit, to initiate any claim for
     refund, to file any amended Non-Federal Separate Tax Return, to
     contest, resolve and defend against any assessment, notice of
     deficiency, or other adjustment or proposed adjustment of Taxes
     (including the right to agree to any assessment, deficiency, or
     settlement of any of the foregoing items) relating to any Non-
     Federal Separate Tax Return filed with respect to any Pre-Closing
     Period or Straddle Period; provided, however, that CNI or CLC, as
     the case may be, shall not take any of the foregoing actions with
     respect to any Non-Federal Separate Tax matter for which Seller
     may have liability under this Agreement without the prior written
     consent of Seller, which consent shall not be unreasonably
     withheld.  Seller and the Affiliated Group will execute and
     deliver to CNI or CLC (or a subsidiary or affiliate thereof), as
     the case may be, promptly upon request, such powers of attorney
     as may be reasonably necessary to authorize CNI or CLC (or a
     subsidiary or affiliate thereof), as the case may be, to extend
     statutes of limitations and receive refunds that CNI or CLC, as
     the case may be, may reasonably consider to be necessary to
     contest any Audit pursuant to this Section 6.2.

          Section 7.  Mutual Cooperation.  Seller, Buyer, CNI, and CLC
     shall cooperate with each other in the filing of any Tax Return,
     amendment thereto, or consent contemplated by this Agreement and
     to take such action as such other party may reasonably request,
     including (but not limited to):

               a.  providing data for the preparation of any original
     or amended Tax Returns;

               b.  cooperating in any Audit, including the execution
     of limited powers of attorney that do not permit the entry into
     of any settlement agreement, unless otherwise mutually agreed to
     by the parties;

               c.  filing protests or otherwise contesting any Audit,
     including the filing of petitions for redetermination or prose-
     cuting actions for refund in any court and pursuing the appeal of
     any such actions;

               d.  retaining and providing on demand books, records,
     documentation or other information relating to any Tax Return
     until the expiration of the applicable statute of limitation
     (giving effect to any extension, waiver, or mitigation thereof),
     providing additional information and explanation of material
     provided hereunder, and the use of the parties' commercially
     reasonable efforts to obtain any documentation from a governmen-
     tal authority or third party that may be necessary or helpful in
     connection with the foregoing.

          Section 8.  Resolution of Certain Conflicts.  In the event
     that the parties cannot agree on the calculation of the amount of
     any liability for Taxes covered by this Agreement and/or the
     Indemnity Amount, the parties will engage an independent, certi-
     fied public accounting firm of national reputation, reasonably
     acceptable to each party, to make such calculation and the
     decision of such firm will be conclusive.  The cost of such
     engagement will be borne solely by the party that does not
     prevail in substantial part in the determination of the firm that
     is engaged; provided, however, that if such firm determines that
     neither party prevailed in substantial part, the cost of such
     engagement shall be shared equally by Seller and Subsidiary.

          Section 9.  Reorganization Status.  On or prior to the
     second anniversary of the Closing Date (as defined in the Merger
     Agreement), (i) Seller shall not dispose of the stock issued to
     Seller in the Mergers (as defined in the Merger Agreement) and
     (ii) Buyer and the Companies shall not (a) cease to conduct the
     business of the Companies, (b) dispose, transfer or distribute a
     significant portion of the assets of the Companies, (c) dispose
     of the stock of the Companies, or (d) repurchase the stock issued
     to Seller in the Mergers, which action such party actually
     believes, after consultation with such party's tax counsel,
     should, taken alone or together with other actions of such party,
     cause either of the Mergers to fail to qualify as a reorganiza-
     tion within the meaning of Section 368(a) of the Code.

          Section 10.  General Provisions.

               a.  Effectiveness.  This Agreement will be effective
     from and after the earlier of the CNI Deconsolidation Date and
     the CLC Deconsolidation Date; provided, however, the obligations
     of the parties under Sections 4 and 5 hereof shall continue in
     effect after any termination of this Agreement for a period
     ending 30 days after the later of the last day on which a Rede-
     termination may be made against the Affiliated Group, a Combined
     Group, Buyer, CNI, or CLC for (i) any Pre-Closing Period or (ii)
     any Straddle Period, during which CNI Group and/or CLC Group was
     a member of the Affiliated Group and/or a Combined Group.

               b.  Entire Agreement; Binding Effect.  This Agreement
     (a) constitutes the entire agreement and supersedes all other
     agreements and understandings, both written and oral, between the
     parties with respect to the subject matter hereof and (b) shall
     not be assigned by either party (by operation of law or other-
     wise) without the prior written consent of the other party.

               c.  Severability.  In case any one or more of the
     provisions contained in this Agreement should be invalid, illegal
     or unenforceable, the enforceability of the remaining provisions
     hereof will not in any way be effected or impaired thereby.

               d.  Time of Payment.  Any payment required to be made
     under this Agreement for which the terms of payment are not
     specifically provided elsewhere in this Agreement shall be paid
     within 30 days following the date on which the amount of the
     underlying liability to which such payment relates is paid.  Any
     amount required to be paid under this Agreement, which is not
     paid by the end of such 30-day period, will thereafter bear
     interest at the large corporate underpayment rate specified in
     Section 6621(c) of the Code (or any successor provision thereto)
     from the date of such payment to the appropriate Tax Authority to
     the date of full payment to the appropriate party hereunder.

               e.    Applicable Law.  This Agreement shall be gov-

     The address or facsimile number of a party, for the purposes of
     this Section 9(f), may be changed by giving written notice to the
     other party of such change in the manner provided herein for
     giving notice.  Unless and until such written notice is received,
     the addresses and facsimile numbers provided herein shall be
     deemed to continue in effect for all purposes hereunder.

               g.  Amendment and Waiver.  No amendment of any provi-
     sion of this Agreement shall in any event be effective, unless
     the same shall be in writing and signed by the parties hereto. 
     Any failure of any party to comply with any obligation, agreement
     or condition hereunder may only be waived in writing by the other
     parties, but such waiver shall not operate as a waiver of, or
     estoppel with respect to, any subsequent or other failure.  No
     failure by any party to take any action against any breach of
     this Agreement or default by the other parties shall constitute a
     waiver of such party's right to enforce any provision hereof or
     to take any such action.

               h.  Parties in Interest.  This Agreement shall be
     binding upon and inure solely to the benefit of each party hereto
     and, subject to Section 9(b) hereof, their respective successors
     and assigns, and nothing in this Agreement, express or implied,
     is intended to confer upon any other person any rights or reme-
     dies of any nature whatsoever under or by reason of this Agree-
     ment.

               i.  No Third-Party Beneficiaries.  This Agreement is
     solely for the benefit of the parties to this Agreement and the
     other members of the Affiliated Group and should not be deemed to
     confer upon third parties any remedy, claim, liability, reim-
     bursement, claim of action or other right in excess of those
     existing without this Agreement.

               j.  Alternative Minimum Tax.  All Federal Income Tax
     computations with respect to the federal alternative minimum tax
     shall be made in a manner that is consistent with Proposed
     Regulation SECTION 1.1502-55.  Seller shall allocate alternative
     minimum tax credits, if any, to CNI Group and CLC Group in
     accordance with Proposed Regulation SECTION 1.1502-55.  Thus, the
     amount of any alternative minimum tax credits allocable to CNI
     Group and/or CLC Group and not utilized with respect to Pre-
     Closing Periods will be allocated to CNI Group and/or CLC Group
     as of the Deconsolidation Date.

               k.  Federal Income Tax Return Closing Date.  Unless
     otherwise required by the Internal Revenue Service or a court of
     competent jurisdiction, Seller and Buyer agree to file all
     Federal Income Tax Returns, and to take all other actions relat-
     ing to Federal Income Taxes, in a manner consistent with the
     position that CLC Group and CNI Group are members of the Affili-
     ated Group for all days from the date hereof through and includ-
     ing the CNI Deconsolidation Date and the CLC Deconsolidation Date
     respectively.

               l.  Ratable Allocation Election.  The parties agree
     that, to the extent permitted by applicable law and regulations,
     they will make all Federal Income Tax computations with respect
     to the Pre-Closing Period ending on the relevant Deconsolidation
     Date and the immediately following taxable period of CNI Group
     and/or CLC Group, as the case may, pursuant to the ratable
     allocation method (as specified in Treas. Reg. SECTION 1.1502-
     76(b)(2)(ii)) and the parties shall execute and file all Tax
     forms and documents necessary thereto (including the statement(s)
     specified in Treas. Reg. SECTION 1.1502-76(b)(2)(ii)(D)).

               m.  Reattribution of Losses.  Seller shall not make any
     election to reattribute losses with respect to the CNI Group or
     CLC Group under Treas. Reg. SECTION 1.1502-20(g), without the prior
     written consent of Buyer; provided, further, that no losses with
     respect to the CNI Group or CLC Group that are attributable to a
     Post-Closing Period shall be carried to any Pre-Closing Period.

               n.  Treatment of Tax Payments and Refunds.  The parties
     agree that, to the extent permitted by applicable law and regula-
     tions, they will treat any payment or refund of Federal Taxes and
     Non-Federal Taxes pursuant to this Agreement as payment of the
     Federal Tax or Non-Federal Tax liability of the party making such
     payment or as the refund of the Federal Tax or Non-Federal Tax
     liability of the party entitled to such refund.

               o.    Counterparts.  This Agreement may be executed in
     any number of counterparts and by the different parties hereto on
     separate counterparts, each of which when so executed and deliv-
     ered shall be deemed an original, but all of which together shall
     constitute one and the same instrument.

               p.  Headings; Pronouns and Conjunctions.  The section
     and other headings contained in this Agreement are for reference
     purposes only and shall not affect in any way the meaning or
