         ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

              On October 15, 1996, the Registrant, The McGraw-Hill

         Companies, Inc., a New York corporation ("McGraw-Hill"),

         acquired:  (i) all of the outstanding shares of capital stock

         of Times Mirror Higher Education Group, Inc., a Delaware

         corporation ("TMHE"), from The Times Mirror Company, a Delaware

         corporation ("Times Mirror"), and (ii) certain assets and

         liabilities of Mosby-Year Book, Inc., a Missouri corporation

         and a wholly-owned subsidiary of Times Mirror ("Mosby"),

         relating to Mosby's college-level life and physical science

         text publishing business.

              The parties had originally entered into an Exchange

         Agreement dated as of July 3, 1996, as amended by an Amendment

         dated October 15, 1996 (collectively, the "Exchange

         Agreement").  

              In exchange for acquiring the stock of TMHE and certain

         college text assets and liabilities of Mosby (collectively, the

         "Times Mirror College Business"), McGraw-Hill sold to Times

         Mirror all of the outstanding shares of capital stock of its

         subsidiary Shepard's/McGraw-Hill, Inc., a Delaware corporation

         ("Shepard's").  At the closing, McGraw-Hill also received a

         cash payment from Times Mirror in the amount of $25,000,000,

         less certain specified offsets.  In addition, the Exchange

         Agreement provides for a post-closing adjustment to the

         purchase price which may result in the payment of cash by

         either party to the other party.<PAGE>





                                        3

              The Times Mirror College Business is engaged in the

         business of publishing textbooks and other materials and

         products for the college education market.  Shepard's is

         engaged in the business of publishing legal citation materials.

              Simultaneously with the closing under the Exchange

         Agreement, McGraw-Hill sold the William C. Brown printing

         facility in Dubuque, Iowa to Quebecor Printing (USA) Corp.

         These printing operations were part of the Times Mirror College

         Business.  It is anticipated that Quebecor Printing (USA) Corp.

         will continue the printing operations and will provide printing

         services to McGraw-Hill.

              The terms of the Exchange Agreement, including the

         agreement with respect to the consideration, were arrived at

         pursuant to arms-length negotiations between representatives of

         McGraw-Hill, on the one hand, and representatives of Times

         Mirror, on the other hand.  The transaction was approved by the

         McGraw-Hill Board of Directors on June 26, 1996.

              No material relationship exists (i) between McGraw-Hill

         and Times Mirror; (ii) between any of McGraw-Hill's subsidiary

         corporations or affiliates, on the one hand, and Times Mirror

         or any of Times Mirror's subsidiary corporations or affiliates,

         on the other hand; or (iii) between Times Mirror and any

         director or officer of McGraw-Hill, or any associate of any

         McGraw-Hill director or officer.

         Exhibit 2 and is incorporated in this Form 8-K Report by

                                       -13-<PAGE>







         after the Closing Date (except that those Mosby Assets neces-
         sary or convenient for the performance of Mosby's obligations
         under the Mosby Transition Services Agreement will be trans-
         ferred as soon as practicable after the Termination Date
         thereof (as defined therein)), it being understood that the
         cost of transferring such Mosby Assets shall be borne by
         McGraw-Hill.

                   (e)  Delivery of the International Assets.  The In-
         ternational Assets will be in the possession or control of the
         TMIP Entities on the Closing Date.  Prior to the Closing, (A)
         Times Mirror will provide McGraw-Hill with a schedule setting

         therein)), it being understood that the cost of transferring
         such International Assets shall be borne by McGraw-Hill.

                   (f)  Assignment of Contracts and Rights.  Anything in
         this Agreement to the contrary notwithstanding, this Agreement
         shall not constitute an agreement to assign any of the Mosby
         Assets, the International Assets or any asset of TMHE, the TMHE
         Subsidiaries or Shepard's or any claim or right or any benefit
         arising thereunder or resulting therefrom if an attempted as-
         signment thereof, without the consent of a third party thereto,
         would constitute a breach or other contravention thereof or in
         any way adversely affect the rights of McGraw-Hill or Times
         Mirror or any of their affiliates thereunder.  McGraw-Hill and
         Times Mirror will use reasonable efforts, and will cause their
         affiliates to use reasonable efforts (but without any payment
         of money by McGraw-Hill or Times Mirror or their affiliates) to
         obtain the consent of the other parties to any such asset or
         any claim or right or any benefit arising thereunder for the
         assignment thereof as permitted hereby.  If such consent is not
         obtained, or if an attempted assignment thereof would be inef-
         fective or would adversely affect the rights of the transferor
         thereunder so that the transferee would not in fact receive all
         such rights, the transferor and the transferee will cooperate
         in a mutually agreeable arrangement under which the transferee
         would obtain the benefits and assume the obligations thereunder


                                       -14-<PAGE>







         in accordance with this Agreement, including subcontracting,
         sublicensing or subleasing to the transferee, or under which
         the transferor would enforce for the benefit of the transferee,
         with the transferee assuming the transferor's obligations, any
         and all rights of the transferor against a third party thereto.
         The transferor will pay promptly to the transferee when re-
         ceived all monies received by the transferor after the Closing
         Date under any of the such assets or any claim or right or any
         benefit arising thereunder.

                   Provided that McGraw-Hill and its affiliates (includ-
         ing Shepard's) use reasonable efforts to obtain such consents,
         Times Mirror agrees that neither McGraw-Hill nor its affiliates
         shall have any liability whatsoever arising out of or relating
         to the failure to obtain any consents that may have been or may
         be required in connection with the transactions contemplated by
         this Agreement or because of the default, acceleration or ter-
         mination of any asset of Shepard's as a result thereof, to the
         extent such matters are disclosed on Schedule 6.02 or are not
         material to Shepard's.  Times Mirror further agrees that no
         condition shall be deemed not to be satisfied as a result of
         (i) the failure to obtain any such consent or as a result of
         any such default, acceleration or termination or (ii) any law-
         suit, action, claim, proceeding or investigation commenced or
         threatened by or on behalf of any persons arising out of or
         relating to the failure to obtain any such consent or any such
         default, acceleration or termination, in each case to the
         extent such matters are disclosed on Schedule 6.02 or are not
         material to Shepard's. 

                   Provided that Times Mirror and its affiliates (in-
         cluding TMHE and Mosby) use reasonable efforts to obtain such
         consents, McGraw-Hill agrees that neither Times Mirror nor its
         affiliates shall have any liability whatsoever arising out of
         or relating to the failure to obtain any consents that may have
         been or may be required in connection with the transactions
         contemplated by this Agreement or because of the default,
         acceleration or termination of any asset included in the Col-
         lege Publishing Business as a result thereof, to the extent
         such matters are disclosed on Schedule 5.03 or are not material
         to the College Publishing Business.  McGraw-Hill further agrees
         that no condition shall be deemed not to be satisfied as a
         result of (i) the failure to obtain any such consent or as a
         result of any such default, acceleration or termination or (ii)
         any lawsuit, action, claim, proceeding or investigation com-
         menced or threatened by or on behalf of any persons arising out
         of or relating to the failure to obtain any such consent or any
         such default, acceleration or termination, in each case to the
         extent such matters are disclosed on Schedule 5.03 or are not
         material to the College Publishing Business.

                   Section 5.01.  Organization and Authority of Times
         Mirror.  Times Mirror is a corporation duly organized, validly
         existing and in good standing under the laws of the State of
         Delaware.  Times Mirror has all requisite corporate power and
         authority to execute and deliver this Agreement and to consum-

         porate action required to have been taken by or on behalf of
         Times Mirror by applicable law or its charter documents has
         been taken to authorize (a) the approval, execution and deliv-
         ery on behalf of Times Mirror of this Agreement and (b) the
         performance by Times Mirror of its obligations under this
         Agreement and the consummation of the transactions contemplated
         hereby.  This Agreement constitutes a valid and binding agree-
         ment of Times Mirror, enforceable against it in accordance with
         its terms, except (i) as the same may be limited by applicable
         bankruptcy, insolvency, moratorium or similar laws of general
         application relating to or affecting creditors' rights, includ-
         ing, without limitation, the effect of statutory or other laws
         regarding fraudulent conveyances and preferential transfers,
         and (ii) for the limitations imposed by general principles of
         equity (the foregoing exceptions set forth in clauses (i) and
         (ii) being referred to as the "Enforceability Exceptions").

                   Section 5.02.  Organization and Authority of Mosby.
         Mosby is a corporation duly organized, validly existing and in
         good standing under the laws of the State of Missouri.  Mosby
         has all requisite corporate power and authority to execute and
         deliver this Agreement and to consummate the transactions con-
         templated hereby.  All necessary corporate action required to
         have been taken by or on behalf of Mosby by applicable law or
         its charter documents has been taken to authorize (a) the ap-
         proval, execution and delivery on behalf of Mosby of this
         Agreement and (b) the performance by Mosby of its obligations
         under this Agreement and the consummation of the transactions

         binding agreement of Mosby, enforceable against it in accor-
         dance with its terms, except as the same may be limited by the
         Enforceability Exceptions.

                   Section 5.03.  No Breach.  The execution and delivery
         of this Agreement by Times Mirror and Mosby do not, and the
         consummation of the transactions to which any of Times Mirror,
         Mosby, TMHE or any other affiliate of Times Mirror is a party


                                       -20-<PAGE>







         contemplated hereby will not, (i) violate or conflict with the
         Charter or Bylaws of Times Mirror, Mosby, TMHE or any such af-
         filiate or (ii) except as set forth on Schedule 5.03 hereto,
         constitute a material breach or default or give rise to any
         lien, third-party right of termination, cancellation, material
         modification or acceleration under any material agreement, un-
         derstanding or undertaking to which Times Mirror, Mosby, TMHE
         or any such affiliate is a party or by which any of them is
         bound, or any material law, rule or regulation to which any of
         them or any material portion of the assets of any of them is
         subject.

                   Section 5.04.  Governmental Consents and Approvals.
         Neither the execution and delivery of this Agreement by Times
         Mirror and Mosby nor the consummation of the transactions to
         which any of Times Mirror, Mosby, TMHE or any other affiliate
         of Times Mirror is a party contemplated hereby will require any
         consent, approval, authorization or permit of, or filing with
         or notification to, any governmental or regulatory authority,
         except (i) for notification pursuant to, and expiration or ter-
         mination of the waiting period under, the HSR Act and (ii)
         where the failure to obtain such consent, approval, authoriza-
         tion or permit, or to make such filing or notification, would
         not prevent Times Mirror, Mosby, TMHE or any such affiliate
         from performing its respective obligations under this Agreement
         without having a material adverse effect on the business,
         financial condition or results of operations of the College
         Publishing Business, taken as a whole.

                   Section 5.05.  Organization and Standing of TMHE and
         its Subsidiaries.  TMHE is a corporation duly organized and
         validly existing under the laws of the State of Delaware.  Each
         of the subsidiaries of TMHE listed on Schedule 5.08 is duly
         organized and validly existing under the laws of the jurisdic-
         tion in which it is organized.  (The entities referred to on
         Schedule 5.08, other than Burr Ridge Parkway Limited Partner-
         ship, are referred to herein as the "TMHE Subsidiaries.")  Each
         of TMHE and the TMHE Subsidiaries has all requisite corporate
         power and authority and, to the Knowledge of Times Mirror, pos-
         sesses all governmental franchises, licenses, permits, authori-
         zations and approvals necessary to enable it to carry on its
         business as presently conducted other than such franchises,
         licenses, permits, authorizations and approvals the lack of
         which would not have a material adverse effect on the business,
         financial condition or results of operations of TMHE and the
         TMHE Subsidiaries taken as a whole.  Each of TMHE and the TMHE
         Subsidiaries is duly qualified and in good standing to do busi-
         ness in each jurisdiction in which the nature of its business
         or the ownership, leasing or holding of its properties makes
         such qualification necessary, except such jurisdictions where


                                       -21-<PAGE>







         the failure to be so qualified or in good standing would not
         have a material adverse effect on the business, financial con-
         dition or results of operations of TMHE or the TMHE Subsidiar-
         ies taken as a whole.  Times Mirror has made available to
         McGraw-Hill true and complete copies of (i) the Certificate of
         Incorporation, as amended to date, and the Bylaws, as in effect
         on the date of this Agreement, of TMHE and (ii) the stock cer-
         tificates and transfer records and the minute books of TMHE.

                   Section 5.06.  Capital Stock of TMHE.  The authorized
         capital stock of TMHE consists of 1,000 shares of common stock,
         par value $1.00 per share, of which 200 shares, constituting
         the TMHE Shares, are duly authorized and validly issued and
         outstanding, fully paid and nonassessable.  Except for the TMHE
         Shares, there are no shares of capital stock or other equity
         securities of TMHE outstanding.  The TMHE Shares have not been
         issued in violation of, and none of the TMHE Shares is subject
         to, any preemptive or subscription rights.  There are no out-
         standing warrants, options, "phantom" stock rights, agreements,
         convertible or exchangeable securities or other commitments
         (other than this Agreement) pursuant to which Times Mirror or
         TMHE is or may become obligated to issue, sell, purchase, re-
         turn or redeem any shares of capital stock or other securities
         of TMHE, and no equity securities of TMHE are reserved for is-
         suance for any purpose.  Other than this Agreement, the TMHE
         Shares are not subject to any voting trust agreement or other
         contract, agreement, arrangement, commitment or understanding,
         including any such agreement, arrangement, commitment or under-
         standing restricting or otherwise relating to the voting, divi-
         dend rights or disposition of the TMHE Shares.

                   Section 5.07.  Title to and Transfer of the TMHE
         Shares.  Times Mirror is the record and beneficial owner of the
         TMHE Shares and has good and marketable title thereto, free and
         clear of any liens, claims, encumbrances, security interests,
         options, charges and restrictions of any kind.  Assuming
         McGraw-Hill has the requisite power and authority to be the
         lawful owner of the TMHE Shares, upon delivery to McGraw-Hill
         at the Closing of certificates representing the TMHE Shares,
         duly endorsed by Times Mirror for transfer to McGraw-Hill, and
         the completion of the other deliveries at the Closing contem-
         plated by Article 2, good and marketable title to the TMHE
         Shares will pass to McGraw-Hill, free and clear of any mort-
         gages, liens, claims, encumbrances, security interests, op-
         tions, charges and restrictions of any kind ("Liens") other
         than those arising from acts of McGraw-Hill or its affiliates.  

                   Section 5.08.  Equity Interests.  Except as set forth
         on Schedule 5.08, TMHE does not directly or indirectly own any
         capital stock of or other equity interests in any corporation,


                                       -22-<PAGE>







         partnership or other entity.  Except as set forth on Schedule
         5.08, TMHE owns all of the equity interests in the TMHE Subsid-
         iaries.  The equity interests in the TMHE Subsidiaries have not
         been issued in violation of, and none of such interests is sub-
         ject to, any preemptive or subscription rights.  There are no
         outstanding warrants, options, "phantom" stock rights, agree-
         ments, convertible or exchangeable securities or other commit-
         ments (other than this Agreement) pursuant to which Times
         Mirror or any affiliate thereof is or may become obligated to
         issue, sell, purchase, return or redeem any shares of capital
         stock or other securities of any TMHE Subsidiary, and no equity
         securities of any TMHE Subsidiary are reserved for issuance for
         any purpose.  Other than this Agreement, the equity interests
         in the TMHE Subsidiaries are not subject to any voting trust
         agreement or other contract, agreement, arrangement, commitment
         or understanding, including any such agreement, arrangement,
         commitment or understanding restricting or otherwise relating
         to the voting, dividend rights or disposition of the such in-
         terests.

                   Section 5.09.  Financial Statements.  

                   (a)  TMHE Financial Statements.  The financial state-
         ments set forth on Schedule 5.09(a), which consist of (i) the

         fairly, in all material respects, TMHE's consolidated financial
         position and the consolidated results of its operations and
         cash flows as of the dates thereof and for the periods covered
         thereby.  The TMHE Balance Sheet and the unaudited condensed
         consolidated statements of operations, shareholder's equity and
         cash flows referred to in clause (ii) above were prepared on a
         basis consistent with the audited consolidated financial state-
         ments of TMHE for the year ended December 31, 1995, except that
         Times Mirror's intercompany account balance with TMHE as of
         March 31, 1996 was contributed to the capital of TMHE, and
         include all adjustments that management considers necessary for
         a fair presentation of the results of operations for such
         period.

         4974, 4975, 4976 or 4980B of the Code.  Except as described on

         has been operated and administered in all material respects in
         accordance with its terms and applicable laws, including, but

         tended to be a qualified plan under Code Section 401 has re-
         ceived a favorable determination letter to that effect (a copy
         of which has been delivered to McGraw-Hill) covering all of the
         provisions applicable to tax qualified plans introduced by the
         Tax Reform Act of 1986 and nothing has occurred since the issu-
         ance of such letter that would adversely affect the Tax quali-
         fication of any such College Publishing Business Plan.  There


                                       -32-<PAGE>

         ness, threatened claims by or on behalf of any of the College
         Publishing Business Plans by any employee, former employee or
         beneficiary covered under any such College Publishing Business
         Plan or otherwise involving any such College Publishing Busi-
         ness Plan (other than individual claims for benefits arising in
         the ordinary course).

                   (c)  Multiemployer Plan Liabilities.  Except as dis-
         closed on Schedule 5.17(c), none of Times Mirror, TMHE, any
         TMHE Subsidiary or any ERISA Affiliate of TMHE is, or has been
         within the last six years, obligated to contribute, on behalf
         of any current or former employee of TMHE or any TMHE Subsidi-
         ary, to a multiemployer plan (as defined in Section 3(37) of
         ERISA) and no such ERISA Affiliate of TMHE is liable or rea-
         sonably expected to be liable for any withdrawal liability un-
         der Section 4201 of ERISA.

                   (d)  Accumulated Funding Deficiencies; Liens.  None
         of the College Publishing Business Plans or any trust estab-
         lished thereunder has any accumulated funding deficiency (as
         defined in Section 302 of ERISA and Section 412 of the Code),
         whether or not waived, as of the last day of the most recent
         fiscal year of each of the College Publishing Business Plans.
         No contribution failure has occurred with respect to any Col-
         lege Publishing Business Plan sufficient to give rise to a lien
         under Section 302(f) of ERISA.

                   (e)  Employee Welfare Benefit Plans.  With respect to
         any College Publishing Business Plan that is an employee wel-
         fare benefit plan, except as disclosed on Schedule 5.17(e), (i)
         no such College Publishing Business Plan is funded through a
         welfare benefits fund, as such term is defined in Section
         419(e) of the Code and (ii) each such College Publishing Busi-
         ness Plan that is a group health plan, as such term is defined
         in Section 5000(b)(1) of the Code, complies with the applicable
         requirements of Section 4980B(f) of the Code.

                   Section 5.18.  Absence of Changes or Events.  Except
         as set forth on Schedule 5.18, since the date of the TMHE Bal-
         ance Sheet and the Mosby Statement, there has not been a mate-
         rial adverse change in the business, financial condition or
         results of operations of the College Publishing Business, taken
         as a whole, other than changes relating to the economy in gen-
         eral or the College Publishing Business industry in general and
         not specifically relating to the College Publishing Business.
         Except for the accounting adjustments contemplated by Schedule
         4.02(a)(v) and Section 5.09(d) and except as disclosed on
         Schedule 5.18, since the date of the TMHE Balance Sheet and the
         Mosby Statement, Times Mirror has caused the College Publishing

                  REPRESENTATIONS AND WARRANTIES OF McGRAW-HILL

                   McGraw-Hill hereby represents and warrants to Times
         Mirror and Mosby as follows:

                   Section 6.01.  Organization and Authority.  McGraw-
         Hill is a corporation duly organized, validly existing and in
         good standing under the laws of the state of New York.  McGraw-
         Hill has all requisite corporate power and authority to execute
         and deliver this Agreement and to consummate the transactions
         contemplated hereby.  All necessary corporate action required
         to have been taken by or on behalf of McGraw-Hill by applicable
         law or its charter documents has been taken to authorize (i)
         the approval, execution and delivery on behalf of McGraw-Hill
         of this Agreement and (ii) the performance by McGraw-Hill of


                                       -36-<PAGE>







         its obligations under this Agreement and the consummation of
         the transactions contemplated hereby.  This Agreement consti-
         tutes a valid and binding agreement of McGraw-Hill, enforceable
         against McGraw-Hill in accordance with its terms, except as the
         same may be limited by the Enforceability Exceptions.

                   Section 6.02.  No Breach.  The execution and delivery
         of this Agreement by McGraw-Hill do not, and the consummation
         of the transactions contemplated hereby by McGraw-Hill or Shep-
         ard's will not, (i) violate or conflict with the Charter or
         Bylaws of McGraw-Hill or Shepard's or (ii) constitute a mate-
         rial breach or default or (iii) except as set forth on Schedule
         6.02 hereto, give rise to any Lien, third-party right of termi-
         nation, cancellation, material modification or acceleration
         under any material agreement, understanding or undertaking to
         which McGraw-Hill or Shepard's is a party or by which either of
         them is bound, or any material law, rule or regulation to which
         either of them or any material portion of the assets of either
         of them is subject.

                   Section 6.03.  Governmental Consents and Approvals.
         Neither the execution and delivery of this Agreement by McGraw-
         Hill nor the consummation of the transactions to which McGraw-
         Hill or Shepard's is a party contemplated hereby will require
         any consent, approval, authorization or permit of, or filing
         with or notification to, any governmental or regulatory author-
         ity, except (i) for notification pursuant to, and expiration or
         termination of the waiting period under HSR Act and (ii) where
         the failure to obtain such consent, approval, authorization or
         permit, or to make such filing or notification, would not pre-
         vent McGraw-Hill or Shepard's from performing its obligations
         under this Agreement without having a material adverse effect
         on the business, financial condition or results of operations
         of Shepard's.

                   Section 6.04.  Organization and Standing of
         Shepard's.  Shepard's is a corporation duly organized and val-
         idly existing under the laws of the State of Delaware.
         Shepard's has all requisite corporate power and authority and,
         to the Knowledge of McGraw-Hill, possesses all governmental
         franchises, licenses, permits, authorizations and approvals
         necessary to enable it to carry on its business as presently
         conducted other than such franchises, licenses, permits, autho-
         rizations and approvals the lack of which would not have a ma-
         terial adverse effect on the business, financial condition or
         results of operations of Shepard's.  Shepard's is duly quali-
         fied and in good standing to do business in each jurisdiction
         in which the nature of its business or the ownership, leasing




                                       -37-<PAGE>







         or holding of its properties makes such qualification neces-
         sary, except such jurisdictions where the failure be so quali-
         fied or in good standing would not have a material adverse ef-
         fect on the business, financial condition or results of opera-
         tions of Shepard's.  McGraw-Hill has made available to Times
         Mirror true and complete copies of (i) the Certificate of In-
         corporation and the Bylaws, as in effect on the date of this
         Agreement, of Shepard's and (ii) the stock certificates and

                   Section 6.05.  Capital Stock of Shepard's.  The au-
         thorized capital stock of Shepard's consists of 1,000 shares of
         common stock, par value $1.00 per share, of which 1,000 shares,
         constituting the Shepard's Shares, are duly authorized and val-
         idly issued and outstanding, fully paid and nonassessable.  Ex-
         cept for the Shepard's Shares, there are no shares of capital
         stock or other equity securities of Shepard's outstanding.  The
         Shepard's Shares have not been issued in violation of, and none
         of the Shepard's Shares is subject to, any preemptive or sub-
         scription rights.  There are no outstanding warrants, options,
         "phantom" stock rights, agreements, convertible or exchangeable
         securities or other commitments (other than this Agreement)
         pursuant to which McGraw-Hill or Shepard's is or may become
         obligated to issue, sell, purchase, return or redeem any shares
         of capital stock or other securities of Shepard's, and no eq-
         uity securities of Shepard's are reserved for issuance for any
         purpose.  Other than this Agreement, the Shepard's Shares are
         not subject to any voting trust agreement or other contract,
         agreement, arrangement, commitment or understanding, including
         any such agreement, arrangement, commitment or understanding
         restricting or otherwise relating to the voting, dividend
         rights or disposition of the Shepard's Shares.

                   Section 6.06.  Title to and Transfer of the Shepard's
         Shares.  McGraw-Hill is the record and beneficial owner of the
         Shepard's Shares and has good and marketable title thereto,
         free and clear of any Liens.  Assuming Times Mirror has the
         requisite power and authority to be the lawful owner of the
         Shepard's Shares, upon delivery to Times Mirror at the Closing
         of certificates representing the Shepard's Shares, duly en-
         dorsed by McGraw-Hill for transfer to Times Mirror, and the
         completion of the other deliveries at the Closing contemplated
         by Article 2, good and marketable title to the Shepard's Shares
         will pass to Times Mirror, free and clear of any liens, claims,
         encumbrances, security interests, options, charges and restric-
         tions of any kind other than those arising from acts of Times
         Mirror or its affiliates.

         thereby.  Shepard's Balance Sheet and the unaudited condensed
         statements of operations referred to in clause (ii) above were
         prepared on a basis consistent with the financial statements of
         Shepard's for the year ended December 31, 1995, and include all
         adjustments that management considers necessary for a fair pre-
         sentation of the results of operations for such period.

         6.15 sets forth a list, as of the date of this Agreement, of
         all pending, and to the Knowledge of McGraw-Hill, threatened
         lawsuits or claims (other than lawsuits or claims related to

                   Section 6.16.  Employee and Related Matters; ERISA.

                   (a)  Schedule 6.16(a) sets forth each employee pen-

         stock purchase, incentive, deferred compensation, hospitaliza-
         tion, medical, dental, vision, life insurance, accidental death

         uted to by McGraw-Hill or any of its affiliates in which any
         Shepard's Personnel has participated or under which any Shep-
         ard's Personnel has accrued and remains entitled to any ben-
         efits (the "McGraw-Hill Plans").  McGraw-Hill has made avail-

         each McGraw-Hill Plan (or, in the case of any unwritten McGraw-
         Hill Plans, descriptions thereof), (ii) the most recent annual
         report on Form 5500 filed with the IRS with respect to each
         McGraw-Hill Plan (if any such report was required), (iii) the

                                       -44-<PAGE>







         for which such a summary plan description is required, and (iv)
         all other material documents relating to the McGraw-Hill Plans.
         As soon as practicable after the signing of this Agreement,
         McGraw-Hill shall provide to Times Mirror a true complete and
         accurate copy of each trust agreement and group annuity con-
         tract relating to any McGraw-Hill Plan.  Neither Shepard's nor
         any corporation or trade or business (whether or not incor-
         porated) which would be treated as its ERISA Affiliate is li-
         able for any amount under Title IV of ERISA (except for premi-
         ums to the Pension Benefit Guaranty Corporation arising in the
         ordinary course) and no fact or event exists which could rea-
         sonably give rise to such liability.  Except as disclosed on
         Schedule 6.16(a), no Shepard's Personnel is entitled to any
         benefit under any McGraw-Hill Plan by reason of the transac-
         tions contemplated hereby, including, but not limited to, sev-
         erance, stay-pay or retention bonuses, nor any acceleration,
         vesting, distribution or increase in benefits or obligations to
         fund benefits, and no McGraw-Hill Plan includes any common
         stock or other security issued by McGraw-Hill or any ERISA Af-
         filiate of Shepard's among its assets.

                   (b)  Compliance with ERISA and the Code.  None of
         McGraw-Hill, Shepard's, any of the McGraw-Hill Plans or any
         trust created thereunder, or any trustee or administrator
         thereof, has engaged in a transaction in connection with which
         Shepard's would be subject to either a material liability or
         civil penalty assessed pursuant to Section 409, 502(i) or
         502(l) of ERISA or a material Tax imposed pursuant to Section
         4971, 4972, 4974, 4975, 4976 or 4980B of the Code.  Except as
         described on Schedule 6.16(b), each of the McGraw-Hill Plans
         has been operated and administered in all material respects in
         accordance with its terms and applicable laws, including, but
         not limited to, ERISA and the Code.  Except as disclosed on
         Schedule 6.16(b), each McGraw-Hill Plan intended to be a
         qualified plan under Code Section 401 has received a favorable
         determination letter to that effect (a copy of which has been
         delivered to Times Mirror) covering all of the provisions ap-
         plicable to tax qualified plans introduced by the Tax Reform
         Act of 1986 and nothing has occurred since the issuance of such
         letter that would adversely affect the Tax qualification of any
         such McGraw-Hill Plan.  There are no pending or, to the
         Knowledge of McGraw-Hill, threatened claims by or on behalf of
         any of the McGraw-Hill Plans, by any employee, former employee
         or beneficiary covered under any such Plan, or otherwise
         involving any such McGraw-Hill Plan (other than individual
         claims for benefits arising in the ordinary course).

                   (c)  Multiemployer Plan Liabilities.  Except as dis-
         closed on Schedule 6.16(c) none of McGraw-Hill, Shepard's or
         any ERISA Affiliate of Shepard's is, or has been within the


                                       -45-<PAGE>







         last six years, obligated to contribute, on behalf of any cur-
         rent or former employee of Shepard's, to a multiemployer plan
         (as defined in Section 3(37) of ERISA) and no such ERISA Af-
         filiate of Shepard's is liable or reasonably expected to be
         liable for any withdrawal liability under Section 4201 of
         ERISA.

                   (d)  Accumulated Funding Deficiencies; Liens.  None
         of the McGraw-Hill Plans or any trust established thereunder
         has any accumulated funding deficiency (as defined in Section
         302 of ERISA and Section 412 of the Code), whether or not
         waived, as of the last day of the most recent fiscal year of
         each of the McGraw-Hill Plans.  No contribution failure has
         occurred with respect to any McGraw-Hill Plan sufficient to
         give rise to a lien under Section 302(f) of ERISA.

                   (e)  Employee, Welfare Benefit Plans.  With respect
         to any Plan that is an employee welfare benefit plan, except as
         disclosed on Schedule 6.16(e), (i) no such McGraw-Hill Plan is
         funded through a welfare benefits fund, as such term is defined
         in Section 419(e) of the Code and (ii) each such McGraw-Hill
         Plan that is a group health plan, as such term is defined in
         Section 5000(b)(1) of the Code, complies with the applicable
         requirements of Section 4980B(f) of the Code.

                   Section 6.17.  Absence of Changes or Events.  Except
         as set forth on Schedule 6.17, since the date of Shepard's Bal-
         ance Sheet, there has not been a material adverse change in the
         business, financial condition or results of operations of
         Shepard's, other than changes relating to the economy in gen-
         eral or the legal citations business in general and not speci-
         fically relating to Shepard's.  Except as disclosed on Schedule
         6.17, since the date of the Shepard's Balance Sheet, McGraw-
         Hill has caused the business of Shepard's to be conducted in
         the ordinary course, and neither of McGraw-Hill nor Shepard's
         has taken any action that, if taken after the date of this
         Agreement, would constitute a breach of any of the covenants
         set forth in Article 7.

                   Section 6.18.  Compliance with Applicable Laws.  Ex-
         cept as previously disclosed by McGraw-Hill to Times Mirror in
         writing:

                   (a)  General.  To the Knowledge of McGraw-Hill,
         Shepard's is in compliance with all applicable statutes, laws,
         ordinances, rules, orders and regulations of any governmental
         authority or instrumentality, domestic or foreign, except for
         any such incidents of noncompliance that in the aggregate would
         not have a material adverse effect on the business, financial
         condition or results of operation of Shepard's, taken as a


                                       -46-<PAGE>

         Information.  The TMHE Shares purchased by McGraw-Hill pursuant
         to this Agreement are being acquired for investment only and

         Shares so acquired by it in violation of any of the registra-
         tion requirements of the Securities Act.  McGraw-Hill confirms
         that it is an accredited investor within the meaning of Rule
         501(a) under the Securities Act.  McGraw-Hill has been afforded
         access to such financial and non-financial information material
         of TMHE, its business and the TMHE Shares, of the TMHE Subsid-
         iaries and their businesses, of Mosby and Mosby's College Text
         Business, and of the TMIP Entities and the International Assets
         and International Liabilities, and has been afforded an op-
         portunity to ask questions and receive answers concerning the
         terms and conditions of the purchase and sale of the College
         Publishing Business and to obtain information necessary to ver-
         ify the accuracy of the financial and non-financial information
         furnished to it by Times Mirror and Mosby.

                   Section 6.21.  Certain Material Contracts.  (a)  With
         respect to any Lien, third-party right of termination, cancel-
         lation, material modification or acceleration (collectively,
         "Contractual Change") arising under any of the contracts set
         forth on Schedule 6.02 (the "Certain Contracts") as a result of
         the execution and delivery of this Agreement, or the consumma-
         tion of the transactions contemplated hereby, by McGraw-Hill or
         Shepard's or any failure to obtain consent required under the
         Certain Contracts to the terms of the transactions contemplated
         by this Agreement, or the initial subsequent assignment of any
         of the Certain Contracts to any person, no such Contractual
         Change or such failure to obtain consent (i) will have a mate-
         rial adverse effect on the business, financial condition or
         results of operations of Shepard's (a "Material Adverse Effect
         on Shepard's") other than resulting from (x) the loss of rev-
         enue associated with such contract or (y) the loss of the gen-
         eral reputational or general strategic benefit derived from
         association with the other party to such contract, (ii) will
         result in the loss or abridgement of, or any Lien upon, any of
         Shepard's Intellectual Property, (iii) will trigger any perfor-
         mance or payment obligation on the part of Shepard's or (iv)
         will in any way restrict, limit or constrain Shepard's ability
         to deal with third parties from and after the Closing Date or

         is conducted as of the date hereof, other than (A) in the case
         of clauses (ii), (iii) or (iv), any loss, abridgement, Lien,
         obligation, restriction, limitation or constraint that would
         not have a Material Adverse Effect on Shepard's, or (B) in the
         case of clauses (i), (ii), (iii) or (iv), and with respect to a
         failure to obtain consent, any monetary damages or equitable
         remedies arising from the application of customary contract law
         rather than contractual provisions expressly imposing specific
         remedies.  

                   (b)  Any information, data, services or products ac-
         quired or used by Shepard's in producing, publishing and dis-
         tributing its products which is provided pursuant to any of the
         Certain Contracts can be obtained from alternative sources in a
         manner that would not have a Material Adverse Effect on
         Shepard's.  

                   (c)  There are no contracts, agreements, understand-
         ings or undertakings of Shepard's which would restrict the
         ability of Shepard's to use any of Shepard's Intellectual Prop-
         erty or citation information databases in connection with the
         sale, marketing or distribution of the products of any person,
         including Shepard's, in any medium now or hereafter invented,
         except for restrictions that do not have a Material Adverse
         Effect on Shepard's.

                   (d)  There are no joint product development agree-
         ments or agreements providing for any rights of first refusal
         or similar rights with respect to development of new products
         on an exclusive basis, except for any such agreements or rights
         of first refusal or similar rights that do not have a Material
         Adverse Effect on Shepard's.

                   Section 7.04.  Insurance.  Times Mirror shall keep,
         or cause to be kept, all insurance policies presently main-
         tained relating to TMHE, the TMHE Subsidiaries and their prop-
         erties, to Mosby, with respect to Mosby's College Text Business
         or the Mosby Assets, and to the TMIP Entities, with respect to
         the International Assets, or suitable replacements therefor, in
         full force and effect through the close of business on the
         Closing Date.  Schedule 7.04 sets forth all the insurance poli-
         cies presently owned and maintained by TMHE or the TMHE Sub-
         sidiaries.  Any and all additional insurance policies presently
         maintained relating to TMHE or the TMHE Subsidiaries and their
         properties or Mosby's College Text Business and the Mosby As-
         sets or the International Assets are maintained by Times Mirror

         under any such insurance policies from and after the Closing
         Date with the exception of such policies that do not name Times
         Mirror or any of its other subsidiaries as named insureds.

         signed resignations, effective immediately after the Closing

         the TMHE Subsidiaries and shall take such other action as is
         necessary to accomplish the foregoing.

                   Section 7.06.  Non-Competition.  Times Mirror cov-
         enants and agrees that, if the Closing shall occur, 

                   (a)  for a period of thirty-six (36) months following
         the Closing Date (the "Restricted Period"), Times Mirror and
         its affiliates will not, directly or indirectly, anywhere in
         the world, (1) engage in any business or activity which com-
         petes with or is substantially similar to (i) the business of
         TMHE and the TMHE Subsidiaries in any media (except the health
         management seminar business of Irwin Professional Publishing),
         or (ii) the Mosby College Text Business in any media; or (iii)
         otherwise in the college textbook market in any media in the
         disciplines published by TMHE, the TMHE Subsidiaries, or the
         Mosby College Text Business except for those works within such
         disciplines which are not sold primarily for the core college
         level, such as those works currently published by the Mosby
         medical/nursing division, e.g., the text entitled Human Anatomy
         & Physiology by Elaine N. Marieb (the businesses referred to in
         clauses (i), (ii) and (iii) being referred to in this Section
         7.06 as the "Competing Business"); or (2) become the beneficial
         owner of more than 5% of the common stock (or analogous equity
         interest) of any company or other organization that derives
         more than 5% of its consolidated revenue from the Competing
         Business; provided, however, that the foregoing restrictions
         shall not apply to (1) the business of publishing educational


                                       -55-<PAGE>







         textbooks and related supplementary materials which are prima-
         rily marketed to (i) nurses and nursing students, dentists and
         dentistry students, veterinarians and veterinary medicine stu-
         dents, nutritionists, dieticians and physicians and medical
         students, including, but not limited to, textbooks and related
         supplementary materials in the basic medical sciences of anat-
         omy, physiology, biochemistry, microbiology, pathology, pharma-
         cology, neurosciences and other pre-med and/or graduate level

         business conducted by Times Mirror or any Times Mirror
         affiliate in the newspaper, magazine, legal publishing,
         aviation related publishing and training business;

                   (b)  during the Restricted Period, Times Mirror and
         its Affiliates shall not solicit the employment of any manage-
         rial, marketing, editorial or sales employee of Times Mirror or
         any of its affiliates who becomes an employee of McGraw-Hill or
         any of its affiliates in connection with the transactions con-
         templated by this Agreement;

                   (c)  during the Restricted Period, Times Mirror and
         its Affiliates shall not take any action for the purpose of
         interfering with the relationship, insofar as it relates to the
         Competing Business, between McGraw-Hill (or any affiliates of
         McGraw-Hill) and any author, customer or supplier of McGraw-
         Hill (or any affiliate of McGraw-Hill); and 

                   (d)  until the tenth anniversary of the Closing, nei-
         ther Times Mirror nor any of its affiliates shall use the name
         "Mosby" in the Competing Business.

         Times Mirror agrees that the covenant not to compete set forth
         in paragraph (a) above is reasonable with respect to its dura-
         tion, geographical area and scope.  Notwithstanding any other
         provision of this Agreement, if any of the provisions of this
         Section 7.06 or the application of any provision of this Sec-
         tion 7.06 to any jurisdiction or time period shall be held in-
         valid or unenforceable, the remaining portion of the provisions
         of this Section 7.06 or the application of such portion thereof
         as is held invalid or unenforceable to jurisdictions or time
         periods other than those as to which it is held invalid or un-
         enforceable, shall not be affected thereby.  It is the intent




                                       -56-<PAGE>







         and agreement of Times Mirror and McGraw-Hill that the provi-
         sions of this Section 7.06 be given maximum force, effect and
         application permissible under applicable law.  

                   Section 7.07.  Intercompany Accounts.  Immediately
         prior to the Closing, Times Mirror will cause all intercompany
         accounts between TMHE or any of the TMHE Subsidiaries, on the
         one side, and Times Mirror or any of its subsidiaries or af-
         filiates (other than TMHE and the TMHE Subsidiaries), on the
         other side, to be contributed to capital (in the case of inter-
         company payables on the books of TMHE, its subsidiaries or
         Mosby) or eliminated (in the case of intercompany receivables
         on the books of TMHE, its subsidiaries or Mosby).  Neither the
         Mosby Assets nor the International Assets will include any
         account receivable from Times Mirror or any of its affiliates,
         and neither the Mosby Liabilities nor the International Lia-
         bilities will include any account payable to Times Mirror or
         any of its affiliates.  The foregoing shall not apply to trade
         accounts receivable on the books of TMHE and Mosby due from the
         TMIP Entities.

                   Section 7.08.  Confidentiality.  Times Mirror ac-
         knowledges that the information being provided to it by McGraw-
         Hill is subject to the terms of a confidentiality agreement
         dated June 19, 1996 between McGraw-Hill and Times Mirror (the
         "Shepard's Confidentiality Agreement"), the terms of which are
         incorporated herein by reference.  Effective upon, and only
         upon, the Closing, the Shepard's Confidentiality Agreement will
         terminate only with respect to information relating solely to
         Shepard's, and Times Mirror acknowledges that any and all other
         information provided to it by McGraw-Hill or its representa-
         tives concerning any other subsidiary of McGraw-Hill or any
         other operations of McGraw-Hill shall remain subject to the
         terms and conditions of the Shepard's Confidentiality Agreement
         after the Closing Date.

                   Section 7.09.  No Additional Representations.  Times
         Mirror acknowledges that none of McGraw-Hill, Shepard's or any
         other person has made any representation or warranty, expressed
         or implied, as to the accuracy or completeness of any informa-
         tion regarding Shepard's except as expressly set forth in this
         Agreement or the schedules hereto, and none of McGraw-Hill,
         Shepard's or any other person will have or be subject to any
         liability or indemnification obligation to Times Mirror or any
         other person resulting from the distribution to Times Mirror,
         or Times Mirror's use of, any such information, including,
         without limitation, any information, document, or material made
         available to Times Mirror in certain "data rooms," management
         presentations or in any other form in expectation of the trans-
         actions contemplated by this Agreement.

                   Section 7.10.  Performance of Obligations by Times
         Mirror After Closing Date.  On and after the Closing Date,
         Times Mirror shall, or shall cause Shepard's to, duly, promptly
         and faithfully pay, perform and discharge when due, subject to
         any available defenses and rights of set-off, all obligations
         and liabilities of whatever kind and nature, primary or second-
         ary, direct or indirect, absolute or contingent, known or un-
         known, whether or not accrued, whether arising before, on or
         after the Closing Date, of Shepard's, including, without lim-
         itation, any such obligation or liabilities contained in each
         of the Shepard's Contracts or any agreement, lease, license,
         permit, plan or commitment binding on Shepard's or any of its
         assets that, because it fails to meet the relevant threshold
         amount or term, is not included within the definition of
         Shepard's Contracts, or any plan, fund, program, policy, con-
         tract or arrangement described in Section 6.16, but not re-
         quired to be set forth on Schedule 6.16(a); provided, however,
         that the foregoing shall not apply to any obligation or lia-
         bility that McGraw-Hill agrees to bear under this Agreement.

                   Section 7.11.  Name Change.  Times Mirror shall take
         all measures necessary to cause Shepard's to change the name of
         Shepard's to remove the word "McGraw-Hill" therefrom effective
         immediately after the Closing.

                   Section 7.12.  Grant of License.  At the Closing,
         Mosby shall grant to McGraw-Hill a perpetual, royalty-free
         license to all technology and related documentation in the
         possession or control of Mosby and existing as of the Closing
         necessary to run the software included in such technology and
         to develop, produce, publish, license, sell, or distribute any
         works included in the Mosby Assets (including revisions to the
         works included in the Mosby Assets) containing said technology.
         McGraw-Hill's rights under the license granted pursuant to this
         Section 7.12 shall be limited to the development, production,
         publication licensing, sale and distribution of the works
         referred to in this Section 7.12.  As part of the license
         arrangement during the period of the Mosby Transition Services
         Agreement, Mosby will provide reasonable support with respect
         to the software in order to enable McGraw-Hill to continue
         publishing the effected works.  

                   In the event that the technology licensed hereunder
         includes third-party software or technology for which Mosby is
         obligated to pay a royalty, McGraw-Hill shall, to the extent it
         does not obtain its own third-party license, be responsible for
         the payment of royalties due such third party with respect to
         the sale of works referred to in this Section.

                   Section 7.13.  Purchase of Limited Partner Interest.
         (a)  At the election of McGraw-Hill, Times Mirror shall pur-
         chase the limited partner interest owned as of the Closing by
         TMHE in Burr Ridge Parkway Limited Partnership (the "Partner-
         ship Interest"), for $7.5 million.  Such election may be exer-
         cised by McGraw-Hill by giving written notice to Times Mirror
         on or after January 1, 1998 and on or before January 31, 1998.
         If such election is made, a closing shall take place on the
         fifth Business Day after notice is given to Times Mirror, at

         Times Mirror the Partnership Interest, free and clear of all
         Liens and (ii) Times Mirror will pay $7.5 million to McGraw-
         Hill in immediately available funds.

                   (b)  In the event that the sale to Times Mirror of
         the Partnership Interest pursuant to paragraph (a) of this Sec-
         tion 7.13 takes place, Times Mirror will pay to McGraw-Hill at
         the closing of such purchase an amount equal to the net present
         value (at such time), computed at a discount rate of 7%, of the
         excess of the amount payable (based upon a rate of $28.25 per
         square foot) under the lease between Burr Ridge Parkway Limited
         Partnership, as lessor, and TMHE, as lessee, over the amount
         that would be payable thereunder assuming a rate of $14.50 per
         square foot, for the period beginning January 1, 1998 and
         extending for the term of such lease.

                                       -63-<PAGE>







                   (a)  during the Restricted Period, McGraw-Hill and
         its affiliates will not, directly or indirectly, anywhere in
         the world, (1) engage in any business or activity which com-
         petes with or is substantially similar to the legal citations
         business of Shepard's (such business being referred to in this
         Section 8.06 as the "Competing Business"); or (2) become the
         beneficial owner of more than 5% of the common stock (or analo-
         gous equity interest) of any company or other organization that
         derives more than 5% of its consolidated revenue from the Com-
         peting Business; 

                   (b)  during the Restricted Period, McGraw-Hill and
         its Affiliates shall not solicit the employment of any manage-
         rial, marketing, editorial or sales employee of McGraw-Hill or
         any of its affiliates who becomes an employee of Times Mirror
         or any of its affiliates in connection with the transactions
         contemplated by this Agreement; and

                   (c)  during the Restricted Period, McGraw-Hill and
         its Affiliates shall not take any action for the purpose of
         interfering with the relationship, insofar as it relates to the
         Competing Business, between Times Mirror (or any affiliates of
         Times Mirror) and any author, customer or supplier of Times
         Mirror (or any affiliate of Times Mirror).  

         McGraw-Hill agrees that the covenant not to compete set forth
         in paragraph (a) above is reasonable with respect to its dura-
         tion, geographical area and scope.  Notwithstanding any other
         provision of this Agreement, if any of the provisions of this
         Section 8.06 or the application of any provision of this Sec-
         tion 8.06 to any jurisdiction or time period shall be held in-
         valid or unenforceable, the remaining portion of the provisions
         of this Section 8.06 or the application of such portion thereof
         as is held invalid or unenforceable to jurisdictions or time
         periods other than those as to which it is held invalid or un-
         enforceable, shall not be affected thereby.  It is the intent
         and agreement of Times Mirror and McGraw-Hill that the provi-
         sions of this Section 8.06 be given maximum force, effect and
         application permissible under applicable law.  

                   Section 8.07.  Intercompany Accounts.  Immediately
         prior to the Closing, McGraw-Hill will cause all intercompany
         accounts between Shepard's, on the one side, and McGraw-Hill or
         any of its subsidiaries or affiliates (other than Shepard's),
         on the other side, to be contributed to capital (in the case of
         intercompany payables on the books of Shepard's) or eliminated
         (in the case of intercompany receivables on the books of
         Shepard's).  The assets of Shepard's will not include any
         account receivable from McGraw-Hill or any of its affiliates,



                                       -64-<PAGE>







         and the liabilities of Shepard's will not include any account
         payable to McGraw-Hill or any of its affiliates.

         sets and the International Liabilities), any other subsidiary
         of Times Mirror or any other operations of Times Mirror shall

         lishing Business Confidentiality Agreement after the Closing
         Date.

         "data rooms," management presentations or in any other form in
         expectation of the transactions contemplated by this Agreement.

         known, whether or not accrued, whether arising before, on or
         after the Closing Date, of TMHE, including, without limitation,

         of the Shepard's Income Statement pursuant to Section 8.01(b),

                   (i)  if the sum of (1)(A) the income before income
         taxes of Shepard's shown on the Shepard's Income Statement plus
         (B) Transaction-Related Expenses of Shepard's (to the extent
         such were recorded as expenses on the Shepard's Income State-
         ment) minus the sum of (2)(A) the net change in the intercom-
         pany account balance (without taking into account any charges
         representing Transaction-Related Expenses to such balance or
         any charge relating to income taxes) on the books of Shepard's
         with McGraw-Hill for the period from July 1, 1996 to the Clos-
         ing Date plus (B) income taxes on the amount in clause (1) us-

         with McGraw-Hill for the period from July 1, 1996 to the Clos-
         ing Date plus (B) income taxes on the amount in clause (1) us-

         Times Mirror shall pay to McGraw-Hill, in immediately available
         funds, the amount equal to such difference.

                   For purposes of the calculations in this Section
         9.01(b), intercompany payables to McGraw-Hill on the books of
         Shepard's shall be positive amounts and intercompany
         receivables on the books of Shepard's shall be negative
         amounts, and any cash distributions from Shepard's shall be
         recorded in the intercompany account of Shepard's as
         intercompany receivables.  From the period from July 1, 1996 to
         Closing, no advances to or distributions from Shepard's shall
         be made other than from or to McGraw-Hill.

                   (c)  Any net amount owed to Times Mirror or McGraw-
         Hill under Section 9.01 shall be deemed an adjustment to the
         amount paid under Section 2.03.

                   (d)  All calculations under this Section 9.01 shall
         (i) be made prior to the transactions contemplated by Sections
         7.07 and 8.07 and (ii) shall give no effect to any action that
         constitutes a breach of this Agreement.

         to leave Mosby's name on the inventory included in the Mosby
         Assets in the form it appears thereon on the Closing Date, and
         to continue to use such name with respect to each publication
         included within the Mosby Assets until all inventory of such
         publication existing on the Closing Date has been sold; pro-
         vided, however, that the Mosby name shall not be used on any
         subsequent revision of such publication.  Nothing in this Sec-
         tion 9.02 shall be construed to grant to McGraw-Hill or TMHE
         any rights whatsoever in Mosby's name.  

                   (b)  Times Mirror grants to McGraw-Hill and TMHE the
         right to use Times Mirror's name on the inventory included in
         the College Publishing Business in the form it appears thereon
         on the Closing Date, and to continue to use such name with re-
         spect to each publication included within the College Publish-
         ing Business until all inventory of such publication existing
         on the Closing Date has been sold; provided, however, that the
         Times Mirror name shall not be used on any subsequent revision
         of such publication.  Nothing in this Section 9.02 shall be
         construed to grant to McGraw-Hill or TMHE any rights whatsoever
         in Times Mirror's name.

                   (c)  McGraw-Hill grants to Times Mirror and Shepard's
         the right to use McGraw-Hill's name on the inventory included
         in the assets of Shepard's in the form it appears thereon on


                                       -69-<PAGE>







         the Closing Date, and to continue to use such name with respect
         to each publication included within the assets of Shepard's
         until all inventory of such publication existing on the Closing
         Date has been sold; provided, however, that the McGraw-Hill
         name shall not be used on any subsequent revision of such pub-
         lication.  Nothing in this Section 9.02 shall be construed to
         grant to Times Mirror or Shepard's any rights whatsoever in
         McGraw-Hill's name.

                   Section 9.03.  Cooperation.  McGraw-Hill, Times Mir-
         ror and Mosby shall cooperate with each other and shall cause
         their respective officers, employees, affiliates, agents, audi-
         tors and representatives to cooperate with each other after the
         Closing to ensure (i) the orderly transfer of TMHE, the Mosby
         Assets, the Mosby Liabilities, the International Assets and the
         International Liabilities from Times Mirror, Mosby or the TMIP
         Entities, as the case may be, to McGraw-Hill (or one or more
         subsidiaries of McGraw-Hill) designated by McGraw-Hill and (ii)
         the orderly transfer of Shepard's from McGraw-Hill to Times
         Mirror, and to minimize any disruption to the respective busi-
         nesses of Mosby, TMHE or Shepard's that might result from the
         transactions contemplated hereby.  No party shall be required
         by this Section 9.03 to take any action that would unreasonably
         interfere with the conduct of its business.  

                   Section 9.04.  Publicity.  Times Mirror and McGraw-
         Hill agree that, from the date of this Agreement through the
         Closing Date, no public release or announcement concerning the
         transactions contemplated hereby shall be issued by either
         party without the prior consent of the other party (which con-
         sent shall not be unreasonably withheld), except as such re-
         lease or announcement may be required by law or the rules or
         regulations of any United States or foreign securities ex-
         change, in which case the party required to make the release or
         announcement shall allow the other party reasonable time to
         comment on such release or announcement in advance of such is-
         suance.  Following the Closing, Times Mirror and McGraw-Hill
         shall consult with each other with respect to the preparation
         of any filing with the Securities and Exchange Commission that
         describes or reflects the transactions provided for in this
         Agreement, through and including the Form 10-Q (if any) and
         Form 10-K (unless the Closing occurs after December 31, 1996)
         covering the period in which the Closing occurs.

                   Section 9.05.  Antitrust Notification.  Each of Times
         Mirror and McGraw-Hill will as promptly as practicable, but in
         no event later than ten Business Days following the execution
         and delivery of this Agreement, file with the United States
         Federal Trade Commission (the "FTC") and the United States De-

         if any, required for the transactions contemplated hereby and
         any supplemental information requested in connection therewith
         pursuant to the HSR Act.  Any such notification and report form
         and supplemental information will be in substantial compliance
         with the requirements of the HSR Act.  Each of McGraw-Hill and
         Times Mirror shall furnish to the other such necessary informa-
         tion and reasonable assistance as the other may request in con-
         nection with its preparation of any filing or submission which
         is necessary under the HSR Act.  Times Mirror and McGraw-Hill
         shall keep each other apprised of the status of any communica-
         tions with, and inquiries or requests for additional informa-
         tion from, the FTC and the DOJ and shall comply promptly with
         any such inquiry or request.  Each of Times Mirror and McGraw-
         Hill will use its best efforts to obtain any clearance required
         under the HSR Act for the consummation of the transactions con-
         templated hereby; provided, however, that nothing herein shall
         require (i) McGraw-Hill or any of its subsidiaries to divest or
         hold separate any portion of its assets, the assets of TMHE,
         the Mosby Assets or the International Assets or (ii) Times Mir-
         ror or any of its subsidiaries to divest or hold separate any
         portion of its assets or the assets of Shepard's.

                   Section 9.06.  Records.

                   (a)  On the Closing Date, Times Mirror and Mosby

         the TMIP Entities relating to the business and operations of
         TMHE or the TMHE Subsidiaries, to the extent not then in the
         possession of TMHE, or relating solely and exclusively to
         Mosby's College Text Business, the International Assets or the
         International Liabilities subject to the following exceptions:

                   (i)  Mosby may retain Records until the Termination
              Date of the Mosby Transition Services Agreement (as such
              term is defined therein) and each of the TMIP Entities may
              retain Records until the Termination Date of the TMIP
              Transition Services Agreement (as such term is defined
              therein), in each case to the extent necessary or conve-
              nient for the performance of its respective obligations
              thereunder;

                  (ii)  McGraw-Hill recognizes that certain Records may
              contain incidental information relating to TMHE or Mosby's
              College Text Business or may relate primarily to subsid-
              iaries or divisions of Times Mirror other than TMHE or
              businesses of TMHE previously sold, and that Times Mirror
              or Mosby, as the case may be, may retain such Records and



                                       -71-<PAGE>







              shall provide copies of the relevant portions thereof to
              McGraw-Hill;

                 (iii)  Times Mirror may retain all Records prepared in
              connection with the sale of the TMHE Shares and the Mosby
              Assets, including bids received from other parties and
              analyses relating to TMHE and Mosby's College Text Busi-
              ness; and 

                  (iv)  Times Mirror may retain any Tax returns, reports
              or forms, and McGraw-Hill shall be provided with copies of
              such returns, reports or forms only to the extent that
              they relate to TMHE's or the TMHE Subsidiaries' separate
              returns or separate Tax liability.

                   (b)  On the Closing Date, McGraw-Hill shall deliver
         or cause to be delivered to Times Mirror all Records in the
         possession of McGraw-Hill relating to the business and opera-
         tions of Shepard's to the extent not then in the possession of
         Shepard's, subject to the following exceptions:

                   (i)  Times Mirror recognizes that certain
              Records may contain incidental information relating
              to Shepard's or may relate primarily to subsidiaries
              or divisions of McGraw-Hill other than Shepard's or
              businesses of Shepard's previously sold, and that
              McGraw-Hill may retain such Records and shall provide
              copies of the relevant portions thereof to Times Mir-
              ror;

                  (ii)  McGraw-Hill may retain all Records prepared
              in connection with the sale of the Shepard's Shares,

                 (iii)  McGraw-Hill may retain any Tax returns,
              reports or forms, and Times Mirror shall be provided
              with copies of such returns, reports or forms only to
              the extent that they relate to the separate returns
              or separate Tax liability of Shepard's.  

                   (c)  After the Closing, upon reasonable written no-
         tice, McGraw-Hill, Times Mirror and Mosby agree to furnish or
         cause to be furnished to each other and their representatives,
         employees, counsel and accountants access, during normal busi-

         essary for financial reporting and accounting matters, the
         preparation and filing of any Tax returns, reports or forms or
         the defense of any Tax Claim or assessment; provided, however,
         that such access does not unreasonably disrupt the normal op-
         erations of Times Mirror, McGraw-Hill, Shepard's, TMHE or
         Mosby.

                   Section 9.07.  Further Assurances.  From time to

                   (a)  Offers of Employment.  Schedule 10.01(a) con-
         tains a complete and accurate list of each Mosby's College Text
         Business Employee who will be employed by McGraw-Hill on the

         cause TMHE to offer employment to or to continue to employ) all
         College Publishing Business Employees who are actively employed
         immediately prior to the Closing Date by TMHE, a TMHE Subsid-
         iary or Mosby, subject to the terms and conditions set forth in
         this Article 10.  In addition, each College Publishing Business
         Employee who is on an authorized leave of absence, short- or
         long-term disability leave, worker's compensation leave or va-
         cation leave as of the Closing Date shall be offered employment
         with McGraw-Hill or TMHE following the expiration of the leave


                                       -73-<PAGE>







         of absence to the extent that Times Mirror, TMHE or a TMHE Sub-
         sidiary was obligated to offer employment to such employees
         upon their return to work following such leave, subject to the
         terms and conditions set forth in this Article 10.  All persons
         who are offered employment in accordance with the terms of this
         Section 10.01(a) and who are employed by TMHE, a TMHE Subsid-
         iary or McGraw-Hill on or after the Closing Date are collec-
         tively referred to herein as the "College Publishing Business

         herein to the contrary, on and after the Closing Date, McGraw-
         Hill and TMHE shall have no obligation to employ Mr. G.
         Franklin Lewis and any employee of Mosby's College Text Busi-
         ness who is not listed on Schedule 10.01(a) and Times Mirror
         shall retain all responsibility for any obligations with re-
         spect to such employees who are not College Publishing Business
         Transferred Employees, including the obligation to pay sever-
         ance.  For a period of one year following the Closing Date,
         McGraw-Hill shall not offer employment to any College Publish-
         ing Business Employee who is not employed by McGraw-Hill as of
         the Closing Date.  In addition, nothing contained in this Ar-
         ticle 10 shall be construed to prevent, limit or restrict in
         any way McGraw-Hill's right to terminate any College Publishing
         Business Transferred Employee following the Closing Date.

                   (b)  WARN Act and Other Matters.  McGraw-Hill shall
         be fully responsible for any liability arising under the Worker
         Adjustment and Retraining Notification Act arising in connec-
         tion with the termination of the employment of any College Pub-
         lishing Business Transferred Employee on or after the Closing
         Date.

                   Section 10.02.  Times Mirror's Benefit Plans and Em-
         ployee Related Liabilities.  Times Mirror agrees to continue,

         College Publishing Business Personnel under the College Pub-
         lishing Business Plans in accordance with their terms up to the
         Closing Date.  As of the Closing Date, each College Publishing
         Business Transferred Employee shall cease to be covered by each
         of the College Publishing Business Plans.  Except with respect
         to the liabilities under the College Publishing Business Plans
         that are expressly assumed by McGraw-Hill under this Article
         10, Times Mirror (and not TMHE or the TMHE Subsidiaries) shall
         remain obligated for all benefits and benefit entitlements un-
         der the College Publishing Business Plans which were earned or
         accrued by College Publishing Business Transferred Employees
         and College Publishing Business Retirees prior to the Closing

                   Section 10.03.  McGraw-Hill's Benefit Plans.  On the
         Closing Date, each College Publishing Business Transferred Em-
         ployee shall be covered by the employee benefit plans of
         McGraw-Hill applicable to similarly situated employees of
         McGraw-Hill.  For purposes of McGraw-Hill's employee benefit
         plans, McGraw-Hill shall credit each College Publishing Busi-
         ness Transferred Employee with full credit for employment with
         Times Mirror, TMHE and Mosby prior to the Closing Date for pur-
         poses of eligibility and vesting under McGraw-Hill plans; pro-
         vided, however, that in no event shall McGraw-Hill be obligated
         to grant credit for service to any College Publishing Business
         Transferred Employee for purposes of benefit accrual under any
         McGraw-Hill plan (including, but not limited to, any defined
         benefit pension plan sponsored, maintained or contributed to by
         McGraw-Hill).  Nothing contained in this Article Ten shall ob-
         ligate or commit McGraw-Hill to continue any of its benefit
         plans after the Closing Date or to maintain in effect any such
         plan or any level or type of benefits. 

                   Section 10.04.  Severance Obligations.  McGraw-Hill

         obligations which become payable on or after the Closing Date
         to the College Publishing Business Transferred Employees pursu-
         ant to the individual severance agreements or severance plans
         which are described in Schedule 10.04, other than (i) those
         obligations set forth in Schedule 10.04 that are designated as
         retention or stay-pay, performance bonuses, enhanced profit-
         sharing contributions and (ii) any agreement or arrangement
         covering Mr. G. Franklin Lewis, which will remain obligations
         of Times Mirror.  On or before the Closing Date, Times Mirror
         shall pay to each College Publishing Business Transferred Em-
         ployee all retention or stay-pay and performance bonuses pay-
         able, including those payable under the plans or agreements de-
         scribed in Schedule 10.04, to the extent determinable, or as
         soon as practicable after the Closing Date with respect to
         amounts that are not determinable as of the Closing Date.  In
         addition, on or before the Closing Date, TMHE shall make the
         enhanced profit-sharing contribution to the Wm. C. Brown
         Company Publishers Employees' Profit Sharing Retirement and Tax
         Deferred Investment Plan contemplated in Schedule 10.04.  Such
         contribution shall be considered a Transaction-Related Expense.

                   Section 10.05.  Defined Contribution Plans.  On or
         prior to the Closing Date, Times Mirror shall cause TMHE to
         transfer the sponsorship of the Wm. C. Brown Company Publishers
         Employees' Profit Sharing Retirement and Tax Deferred Invest-
         ment Plan and the Probus Publishing Company 401(k) Savings and
         Investment Plan (the "Brown and Probus Plans") to Times Mirror
         and, on or prior to the Closing Date, Times Mirror shall assume



                                       -75-<PAGE>







         unconditionally from TMHE the sponsorship of the Brown and Pro-
         bus Plans, including, without limitation, the obligation to pay
         all benefits contemplated by such Brown and Probus Plans and
         all obligations with respect to administration, reporting and
         disclosure.  As of the Closing Date, Times Mirror shall cause
         the interests of all College Publishing Business Transferred
         Employees in the Brown and Probus Plans and the Times Mirror
         Savings Plus Plan (the "TM 401(k) Plan") to become fully vested
         and nonforfeitable.  As soon as practicable following the Clos-
         ing Date, Times Mirror shall cause the Brown and Probus Plans
         and the TM 401(k) Plan to distribute all or a portion of the
         account balances of each College Publishing Business Trans-
         ferred Employee who so elects in accordance with the terms of
         such plans.  Subject to the provisions of the applicable
         McGraw-Hill plan and Times Mirror's provision of evidence rea-
         sonably satisfactory to McGraw-Hill that the Brown and Probus
         Plans and the TM 401(k) Plan are qualified under Section 401(a)
         of the Code, McGraw-Hill shall permit the defined contribution
         plan applicable to each College Publishing Business Transferred
         Employee to accept an "eligible rollover contribution" (within
         the meaning of Section 401(a)(31) of the Code) in cash of all
         or a portion of the account balance distributed to such College
         Publishing Business Transferred Employee under the Brown and
         Probus Plans or the TM 401(k) Plan, as the case may be; pro-
         vided, however, that nothing contained herein shall obligate
         McGraw-Hill to accept rollovers in the form of Times Mirror
         stock.  Any amounts rolled over to McGraw-Hill's defined con-
         tribution plan as contemplated in this Section 10.05 shall be
         held and administered in all respects in accordance with the
         provisions of such McGraw-Hill plan as in effect from time to
         time.

                   Section 10.06.  Defined Benefit Plans.  As of the
         Closing Date, the College Publishing Business Transferred Em-
         ployees shall cease to accrue benefits under the Times Mirror
         Pension Plan (the "TM Pension Plan") and TMHE shall cease to be
         a participating employer thereunder.  Times Mirror shall take,
         or cause to be taken, all action as may be necessary (i) to
         effect such cessation of participation and (ii) to cause the
         College Publishing Business Transferred Employees' benefits
         under the TM Pension Plan to become fully vested as of the
         Closing Date.  No assets or liabilities with respect to the
         College Publishing Business Transferred Employees shall be
         transferred as a result of this Agreement from the TM Pension
         Plan to any plan or arrangement established or maintained by
         McGraw-Hill for the benefit of the College Publishing Business
         Transferred Employees.  As of the Closing Date, eligible Col-
         lege Publishing Business Transferred Employees who were covered
         by the TM Pension Plan immediately prior to the Closing Date



                                       -76-<PAGE>







         shall be eligible to participate in a McGraw-Hill defined ben-
         efit pension plan and shall receive credit for purposes of eli-
         gibility and vesting (but not for benefit accrual) under such
         plan for all service with Times Mirror, TMHE, the TMHE Subsi-
         diaries and Mosby prior to the Closing Date.  McGraw-Hill and
         Times Mirror shall provide each other with such records and
         information as may be necessary or appropriate to carry out
         their obligations under this Section 10.06 or for purposes of
         the administration of McGraw-Hill's defined benefit plan.

                   Section 10.07.  Welfare Benefits.  

                   (a)  Times Mirror agrees to continue coverage of Col-
         lege Publishing Business Personnel under the Times Mirror Group
         Benefit Plan and other Plans which are welfare benefit plans up
         to the Closing Date and to provide benefits to or reimburse
         covered College Publishing Business Personnel for eligible
         health care and other eligible welfare benefit expenses and
         services incurred up to the Closing Date in accordance with the
         terms of such Plan.  

                   (b)  In connection with McGraw-Hill's obligation to
         provide welfare benefits to the eligible College Publishing
         Business Transferred Employees under its plans pursuant to Sec-
         tion 10.03, McGraw-Hill shall cause each McGraw-Hill group
         health plan to waive any pre-existing condition exclusions
         thereunder with respect to the College Publishing Business
         Transferred Employees to the extent that such employees are
         enrolled in the applicable group health plan of Times Mirror as
         of the Closing Date.  Notwithstanding any other provision
         herein to the contrary, Times Mirror will retain all of its
         obligations to provide post-retirement medical coverage to (i)
         College Publishing Business Transferred Employees who, as of
         the Closing Date, (a) have been credited with at least ten
         consecutive years of service after attaining age 40 under the
         applicable College Publishing Business Post-Retirement Plan,
         (b) have attained at least age 60 and (c) are otherwise eli-
         gible for such benefits under the terms of the applicable Col-
         lege Publishing Business Post-Retirement Plan in effect as of
         the Closing Date, and (ii) College Publishing Business Retirees
         with respect to expenses and services incurred by such indi-
         viduals on or after the Closing Date in accordance with the
         terms of the applicable College Publishing Business Post-
         Retirement Plan as in effect from time to time with respect to
         similarly situated retirees or employees of Times Mirror; pro-
         vided, however, that in order for any College Publishing Busi-
         ness Transferred Employee to be eligible to participate in any
         College Publishing Business Post-Retirement Plan, such employee
         must expressly elect to participate therein as of his retire-
         ment date with McGraw-Hill.

                   (c)  With respect to any welfare benefit plans main-
         tained at the TMHE level, McGraw-Hill and Times Mirror agree to
         negotiate mutually beneficial transitional arrangements with
         respect to the benefits provided thereunder, which arrangements
         may result in terminating such plans as of the Closing Date or
         providing for the continuation of such plans following the
         Closing Date by TMHE for eligible College Publishing Business
         Transferred Employees.

                   (d)  For purposes of this Section 10.07, an expense
         or service is deemed to be incurred when the medical services
         are performed, or, with respect to welfare benefits other than
         medical or dental benefits, when the event giving rise to such
         expense or service occurs.  

                   Section 10.08.  Modifications.  None of Times Mirror,
         TMHE, the TMHE Subsidiaries or Mosby will change the employment
         status of any College Publishing Business Employee so as to
         promise employment for any specified term of employment.  

                   Section 10.09.  Mutual Cooperation.  McGraw-Hill and
         Times Mirror agree, in a complete, diligent and timely manner,
         to exchange such employee census, actuarial or other data as
         shall be reasonably necessary to calculate benefits under any
         plan and to take any and all actions as shall be reasonably
         necessary or advisable to effect the provisions of this Article
         10.

                   Section 10.10.  Employee Benefits Indemnity.  For a
         period of three years following the Closing Date:

                   (a)  McGraw-Hill shall indemnify and hold Times Mir-
              ror and Mosby harmless from any Losses Times Mirror or
              Mosby may incur as a result of (i) McGraw-Hill's failure
              to honor any obligation expressly assumed under this Ar-
              ticle 10 by McGraw-Hill or a breach by McGraw-Hill of any
              covenant of McGraw-Hill set forth in this Article 10 and
              (ii) any actions taken by McGraw-Hill with respect to any
              College Publishing Business Transferred Employee on or
              after the Closing Date; and

                   (b)  Times Mirror and Mosby shall indemnify and hold
              McGraw-Hill and TMHE harmless from any Losses McGraw-Hill
              or TMHE may incur as a result of (i) Times Mirror's or
              Mosby's failure to honor any obligations expressly re-
              tained or assumed under this Article 10 by Times Mirror or
              Mosby or a breach by Times Mirror or Mosby of any covenant
              of Times Mirror or Mosby set forth in this Article 10,
              (ii) any actions taken by Times Mirror or Mosby with re-
              spect to any College Publishing Business Employee prior to


                                       -78-<PAGE>







              the Closing Date or any College Publishing Business Re-
              tiree and (iii) any failure of any representation or war-
              ranty of Times Mirror or Mosby contained in Section 5.17
              to be true and correct as of the Closing Date. 

                   Section 10.11.  Third-Party Claims.  Nothing in this
         Agreement is intended, or shall be construed, to confer upon
         any person, other than the parties hereto and their successors
         and permitted assigns, any rights or remedies by reason of this
         Article 10.


                                  ARTICLE TEN-A
                           EMPLOYEE AND RELATED MATTERS
                            WITH RESPECT TO SHEPARD'S

                   Section 10A.01.  Continuation of Employment.

                   (a)  Offers of Employment.  Except as otherwise pro-
         vided herein, on or after the Closing Date, Times Mirror shall
         offer employment to (or cause Shepard's to offer employment to
         or to continue to employ) all Shepard's Employees who are ac-
         tively employed immediately prior to the Closing Date by Shep-
         ard's, subject to the terms and conditions set forth in this
         Article 10A.  In addition, each Shepard's Employee who is on an
         authorized leave of absence, short- or long-term disability
         leave, worker's compensation leave or vacation leave as of the
         Closing Date shall be offered employment with Times Mirror or
         Shepard's following the expiration of the leave of absence to
         the extent that McGraw-Hill or Shepard's was obligated to offer
         employment to such employees upon their return to work follow-
         ing such leave, subject to the terms and conditions set forth
         in this Article 10A.  All persons who are offered employment in
         accordance with the terms of this Section 10A.01(a) and who are
         employed by Shepard's or Times Mirror on or after the Closing
         Date are collectively referred to herein as the "Shepard's
         Transferred Employees."  Notwithstanding anything contained
         herein to the contrary, on and after the Closing Date, Times
         Mirror and Shepard's shall have no obligation to employ each of
         Shepard's Employees identified on Schedule 10A.01(a)-1 and
         McGraw-Hill shall retain all responsibility for any obligations
         with respect to such employees.  In addition, nothing contained
         in this Article 10A shall be construed to prevent, limit or re-
         strict in any way Times Mirror's right to terminate any Shep-
         ard's Transferred Employee following the Closing Date.

                   (a)  WARN Act and Other Matters.  Times Mirror shall
         be fully responsible for any liability arising under the Worker




                                       -79-<PAGE>







         Adjustment and Retraining Notification Act arising in connec-
         tion with the termination of the employment of any Shepard's
         Transferred Employee on or after the Closing Date.

                   Section 10A.02  McGraw-Hill's Benefit Plans and Em-
         ployee Related Liabilities.  McGraw-Hill agrees to continue
         coverage of Shepard's Personnel under the McGraw-Hill Plans in
         accordance with their terms up to the Closing Date.  As of the
         Closing Date, each Shepard's Transferred Employee shall cease
         to be covered by each of the McGraw-Hill Plans.  Except with
         respect to the liabilities under the McGraw-Hill Plans that are
         expressly assumed by Times Mirror under this Article 10A,
         McGraw-Hill (and not Shepard's) shall remain obligated for all
         benefits and benefit entitlements under the McGraw-Hill Plans
         which were earned or accrued by Shepard's Transferred Employees
         and Shepard's Retirees prior to the Closing Date and for all
         employment or employment related liabilities or claims relating
         to facts or events that occurred prior to the Closing Date.

                   Section 10A.03.  Times Mirror's Benefit Plans.  On
         the Closing Date, each Shepard's Transferred Employee shall be
         covered by employee benefit plans maintained, sponsored or con-
         tributed to by Times Mirror or one or more of its affiliates
         that provide benefits that in the aggregate are comparable to
         those provided to similarly situated employees of the publish-
         ing industry (the "Replacement Plans").  For purposes of the
         Replacement Plans, Times Mirror shall credit each Shepard's
         Transferred Employee with full credit for employment with
         McGraw-Hill and Shepard's prior to the Closing Date for pur-
         poses of eligibility and vesting.  In no event shall Times Mir-
         ror be obligated to grant credit for service to any Shepard's
         Transferred Employee for purposes of benefit accrual under any
         Replacement Plan (including, but not limited to, any Replace-
         ment Plan that is a defined benefit pension plan).  Nothing
         contained in this Article 10A shall obligate or commit Times
         Mirror to continue any of the Replacement Plans after the Clos-
         ing Date or to maintain in effect any such plan or any level or
         type of benefits. 

                   Section 10A.04.  Severance Obligations.  Times Mirror
         shall assume (or cause Shepard's to assume) responsibility for
         the obligations which become payable on or after the Closing
         Date to the Shepard's Transferred Employees pursuant to the
         individual severance agreements or severance plans which are
         described in Schedule 10A.04, other than those obligations set
         forth in Schedule 10A.04 that are designated as retention or
         stay-pay, performance bonuses, and any obligation pursuant to





                                       -80-<PAGE>







         any plan, agreement or arrangement which will remain obliga-
         tions of McGraw-Hill.  On or before the Closing Date, McGraw-
         Hill shall pay to each Shepard's Transferred Employee all re-
         tention or stay-pay and performance bonuses payable under the
         plans or agreements described in Schedule 10A.04, to the extent
         determinable, or as soon as practicable after the Closing Date
         with respect to amounts that are not determinable as of the
         Closing Date.

                   Section 10A.05.  Defined Contribution Plans.  As of
         the Closing Date, McGraw-Hill shall cause the interests of all
         Shepard's Transferred Employees in the Employee Retirement Ac-
         count Plan of The McGraw-Hill Companies, Inc. and Its Subsid-
         iaries ("ERAP") and the Savings Incentive Plan of The McGraw-
         Hill Companies, Inc. and Its Subsidiaries (the "SIP," and with
         the ERAP, the "McGraw-Hill Defined Contribution Plans") to be-
         come fully vested and nonforfeitable.  As soon as practicable
         following the Closing Date, McGraw-Hill shall cause the McGraw-
         Hill Defined Contribution Plans to distribute all or a portion
         of the account balances of each Shepard's Transferred Employee
         who so elects in accordance with the terms of such plans.  Sub-
         ject to the provisions of the applicable Replacement Plan and
         McGraw-Hill's provision of evidence reasonably satisfactory to
         Times Mirror that the McGraw-Hill Defined Contribution Plans
         are qualified under Section 401(a) of the Code, Times Mirror
         shall permit the Replacement Plan that is a defined contribu-
         tion plan that is applicable to each Shepard's Transferred Em-
         ployee to accept an "eligible rollover contribution" (within
         the meaning of Section 401(a)(31) of the Code) in cash of all
         or a portion of the account balance distributed to such Shep-
         ard's Transferred Employee under the McGraw-Hill Defined Con-
         tribution Plans; provided, however, that nothing contained
         herein shall obligate Times Mirror to accept rollovers in the
         form of McGraw-Hill stock.  Any amounts rolled over to such
         Replacement Plan that is a defined contribution plan as contem-
         plated in this Section 10A.05 shall be held and administered in
         all respects in accordance with the provisions of such Replace-
         ment Plan as in effect from time to time.

                   Section 10A.06.  Defined Benefit Plans.  As of the
         Closing Date, the Shepard's Transferred Employees shall cease
         to accrue benefits under the Employee Retirement Plan of The
         McGraw-Hill Companies, Inc. and Its Subsidiaries (the "McGraw-
         Hill Retirement Plan") and Shepard's shall cease to be a par-
         ticipating employer thereunder.  McGraw-Hill shall take, or
         cause to be taken, all action as may be necessary (i) to effect
         such cessation of participation and (ii) to cause the Shepard's
         Transferred Employees' benefits under the McGraw-Hill Retire-
         ment Plan to become fully vested as of the Closing Date.  No
         assets or liabilities with respect to the Shepard's Transferred


                                       -81-<PAGE>







         Employees shall be transferred as a result of this Agreement
         from the McGraw-Hill Retirement Plan to any plan or arrangement
         established or maintained by Times Mirror for the benefit of
         the Shepard's Transferred Employees.  As of the Closing Date,
         eligible Shepard's Transferred Employees who were covered by
         the McGraw-Hill Retirement Plan immediately prior to the Clos-
         ing Date shall be eligible to participate in a Replacement Plan
         that is a defined benefit pension plan and shall receive credit
         for purposes of eligibility and vesting (but not for benefit
         accrual) under such plan for all service with McGraw-Hill and
         Shepard's prior to the Closing Date.  Times Mirror and McGraw-
         Hill shall provide each other with such records and information
         as may be necessary or appropriate to carry out their obliga-
         tions under this Section 10A.06 or for purposes of the adminis-
         tration of the applicable Replacement Plan.

                   Section 10A.07.  Welfare Benefits.  

                   (a)  McGraw-Hill agrees to continue coverage of
         Shepard's Personnel under the McGraw-Hill group welfare benefit
         plans up to the Closing Date and to provide benefits to or re-
         imburse covered Shepard's Personnel for eligible health care
         and other eligible welfare benefit expenses and services in-
         curred up to the Closing Date in accordance with the terms of
         such plans.  

                   (b)  In connection with Times Mirror's obligation to
         provide welfare benefits to the Shepard's Transferred Employees
         under one or more Replacement Plans pursuant to Section 10A.03,
         to the extent permitted by the terms of the applicable Replace-
         ment Plan, Times Mirror shall cause each Replacement Plan to
         waive any pre-existing condition exclusions thereunder with
         respect to the Shepard's Transferred Employees to the extent
         that such employees are enrolled in the applicable group health
         plan of McGraw-Hill as of the Closing Date.  Notwithstanding

         spect to similarly situated retirees or employees of McGraw-
         Hill; provided, however, that in order for any Shepard's Trans-
         ferred Employee to be eligible to participate in any Shepard's

         participate therein as of his retirement date with Times Mirror

         tained at Shepard's level, Times Mirror and McGraw-Hill agree

         Employees.

         or service is deemed to be incurred when the medical services
         are performed, or, with respect to welfare benefits other than

         expense or service occurs.

         nor Shepard's will change the employment status of any
         Shepard's Employee so as to promise employment for any speci-
         fied term of employment.

         and McGraw-Hill agree, in a complete, diligent and timely man-
         ner, to exchange such employee census, actuarial or other data

              under this Article 10A by McGraw-Hill or a breach by

         directors, employees and agents) against McGraw-Hill for Losses
         suffered or incurred in connection with this Agreement and the
         transactions contemplated hereby.

                   Section 11.06.  Losses Net of Insurance.  The amount
         of any Losses for which indemnification is provided under this

         sion thereof by waiver or otherwise), (b) pursuant to para-

         applicable representation or warranty terminates pursuant to
         Section 13.04, (c) pursuant to paragraphs (c), (d) and (e) of
         Section 11.02, shall survive indefinitely, and (d) pursuant to

         above, such obligations to indemnify and hold harmless shall
         not terminate with respect to any item as to which the person
         to be indemnified or the related party hereto shall have, be-
         fore the expiration of the applicable period, previously made a
         claim by delivering a notice (setting forth the detailed basis
         of such claim) to the indemnifying party.

                   Section 11.08.  Procedures Relating to Indemnifica-
         tion (Except Under Section 11.01).  In order for a party (the
         "indemnified party") to be entitled to any indemnification pro-
         vided for under this Agreement (other than under Section 11.01)
         in respect of, arising out of or involving a claim or demand
         made by any person, firm, governmental authority or corporation
         against the indemnified party (a "Third-Party Claim"), such
         indemnified party must notify the indemnifying party in writ-
         ing, and in reasonable detail, of the Third-Party Claim within
         10 Business Days after receipt by such indemnified party of
         written notice of the Third-Party Claim; provided, however,
         that failure to give such notification shall not affect the
         indemnification provided hereunder except to the extent the
         indemnifying party shall have been actually prejudiced as a
         result of such failure (except that the indemnifying party
         shall not be liable for any expenses incurred during the period
         in which the indemnified party failed to give such notice).
         Thereafter, the indemnified party shall deliver to the indemni-
         fying party, within 5 Business Days after the indemnified par-
         ty's receipt thereof, copies of all notices and documents
         (including court papers) received by the indemnified party
         relating to the Third-Party Claim.

                   If a Third-Party Claim is made against an indemnified
         party, the indemnifying party will be entitled to participate
         in the defense thereof and, if it so chooses, to assume the
         defense thereof with counsel selected by the indemnifying party
         and reasonably satisfactory to the indemnified party.  Should
         the indemnifying party so elect to assume the defense of a
         Third-Party Claim, the indemnifying party will not be liable to
         the indemnified party for legal fees and expenses subsequently
         incurred by the indemnified party in connection with the de-
         fense thereof.  If the indemnifying party assumes such defense,
         the indemnified party shall have the right to participate in
         the defense thereof and to employ counsel, at its own expense,
         separate from the counsel employed by the indemnifying party,
         it being understood that the indemnifying party shall control
         such defense.  The indemnifying party shall be liable for the
         fees and expenses of counsel employed by the indemnified party
         for any period during which the indemnifying party has not as-
         sumed the defense thereof (other than during any period in
         which the indemnified party shall have failed to give notice of
         the Third-Party Claim as provided above).  If the indemnifying
         party chooses to defend or prosecute any Third-Party Claim, all
         the parties hereto shall cooperate in the defense or prosecu-
         tion thereof.  Such cooperation shall include the retention and
         (upon the indemnifying party's request) the provision to the
         indemnifying party of records and information which are reason-
         ably relevant to such Third-Party Claim, and making employees
         available on a mutually convenient basis to provide additional


                                       -88-<PAGE>







         information and explanation of any material provided hereunder.
         Whether or not the indemnifying party shall have assumed the
         defense of a Third-Party Claim, the indemnified party shall not
         admit any liability with respect to, or settle, compromise or
         discharge, such Third-Party Claim without the indemnifying par-
         ty's prior written consent (which consent shall not be unrea-
         sonably withheld).  All Tax Claims shall be governed by Section
         12.06 and 12A.06.

                   For all purposes of this Article 11, an "affiliate"
         of any entity shall include a joint venture to which all or
         substantially all of the assets and liabilities of Shepard's
         are assigned.

         if permissible, similar elections under any applicable state or
         local income tax laws with respect to the transfer of the TMHE
         Shares and the shares of the TMHE Subsidiaries.  Times Mirror,
         McGraw-Hill, TMHE and the TMHE Subsidiaries shall report the

         unless and to the extent required to do so pursuant to a deter-
         mination (as defined in Section 1313(a) of the Code or any sim-
         ilar state or local tax provision).  McGraw-Hill may make elec-
         tions under Section 338 of the Code (and if permissible similar
         elections under any applicable state or local income tax law)
         with respect to the transfer of any non-U.S. incorporated TMHE
         Subsidiary.  Any such election shall be considered a TMHE Elec-
         tion for purposes of this Agreement.

                   (b)  To the extent possible, Times Mirror, McGraw-
         Hill and TMHE shall execute at the Closing any and all forms
         necessary to effectuate the TMHE Elections (including, without
         limitation, Internal Revenue Service Form 8023-A and any simi-
         lar forms under applicable state and local income tax laws (the
         "TMHE Section 338 Forms")).  In the event, however, any TMHE
         Section 338 Forms are not executed at the Closing, Times Mir-
         ror, McGraw-Hill and TMHE shall prepare and complete each such
         TMHE Section 338 Form no later than 15 days prior to the date
         such TMHE Section 338 Form is required to be filed.  Times Mir-
         ror, McGraw-Hill and TMHE shall each cause the TMHE Section 338


                                       -89-<PAGE>







         Forms to be duly executed by an authorized person for Times
         Mirror, McGraw-Hill and TMHE in each case, and shall duly and
         timely file the TMHE Section 338 Forms in accordance with ap-
         plicable tax laws and the terms of this Agreement.

                   (c)  (i)  Times Mirror and McGraw-Hill agree that
         they shall calculate the Modified Aggregate Deemed Sale Price
         (as defined under applicable Treasury Regulations, "MADSP") of
         the assets of TMHE and the TMHE Subsidiaries and the allocation
         of such MADSP and amounts allocable to the Mosby Assets and the
         International Assets (hereinafter collectively referred to as
         the "Purchased Assets") among such assets on the one hand, and
         the computation of the MADSP of the assets of Shepard's on the
         other hand, in the manner set forth in clauses (ii) and (iii)
         below.

                   (ii)  Times Mirror and McGraw-Hill shall agree upon a
         Big Six Accounting Firm to act as the "Appraiser".  The fees
         and expenses of the Appraiser shall be shared equally by Times
         Mirror and McGraw-Hill.  Within 150 days of Closing, the Ap-
         praiser shall deliver to each of McGraw-Hill and Times Mirror a
         determination of the fair market value of each of TMHE and its
         Subsidiaries and the Purchased Assets (the "TM Properties") on
         the one hand, and Shepard's on the other hand, a determination
         of the MADSP of TMHE and the TMHE Subsidiaries and Shepard's,
         and an allocation of the MADSP and the fair market value of the
         Purchased Assets among the assets of the TM Properties and
         Shepard's, respectively.  Each such determination and alloca-
         tion shall be binding upon the parties.

                   (iii)  Times Mirror and McGraw-Hill agree to act in
         accordance with the allocations determined by the Appraiser in
         any relevant Tax Returns or similar filings and not to take a
         position before any taxing authority or otherwise (including in
         any Tax Return) inconsistent with such allocation unless and to
         the extent required to do so pursuant to a determination (as
         defined in Section 1313(a) of the Code or any similar state of
         local law).

                   Section 12.021.  Liability for Taxes; Preparation of
         Returns.  

                   (a)  Times Mirror shall be liable for all Taxes of
         TMHE and the TMHE Subsidiaries for any taxable period that ends
         on or before the Closing Date, including the portion of any
         Straddle Period ending on the Closing Date.  Times Mirror shall
         be liable for all Taxes of Mosby and the TMIP Entities.  Times
         Mirror shall be liable for all transfer, sales or gains Taxes
         arising as a result of the transactions contemplated by this
         Agreement and relating to the transfer of the TMHE Shares and


                                       -90-<PAGE>







         the Purchased Assets, other than transfer or sales taxes based
         upon the value of property transferred and which are imposed by
         law on McGraw-Hill, which shall be paid by McGraw-Hill.

                   (b)  McGraw-Hill and Times Mirror agree that if TMHE
         or any of the TMHE Subsidiaries is permitted but not required
         under applicable state or local Tax laws to treat the Closing
         Date as the last day of a taxable period, McGraw-Hill and Times
         Mirror shall treat such day as the last day of a taxable
         period.

                   (c)  Times Mirror shall prepare or cause to be pre-
         pared and timely filed all federal, state, provincial, local
         and foreign Tax Returns in respect of TMHE and the TMHE Subsid-
         iaries, Mosby, the TMIP Entities, their assets or activities
         that (i) are required to be filed on or before the Closing Date
         or (ii) are required to be filed after the Closing Date and (A)
         are Consolidated Tax Returns or (B) are with respect to Income
         Taxes and are required to be filed on a separate Tax Return
         basis for any tax period ending on or before the Closing Date
         or (C) are required to be filed by Mosby or the TMIP Entities.
         Times Mirror shall pay all Taxes shown as due on such Tax Re-
         turns.  McGraw-Hill shall prepare or cause to be prepared and
         shall file or cause to be filed all other Tax Returns required
         of TMHE and the TMHE Subsidiaries, or in respect of their as-
         sets or activities.  Times Mirror shall reimburse McGraw-Hill
         for its share of the Taxes due with respect to such Tax Re-
         turns, in accordance with Section 12.02(a) and (d) hereof.  Any
         such Tax Returns that include periods ending on or before the
         Closing Date or that include the activities of TMHE or any of
         the TMHE Subsidiaries prior to the Closing Date shall, insofar
         as they relate to TMHE or any of the TMHE Subsidiaries, be on a
         basis consistent with past practices for such Tax Returns filed
         in respect of TMHE or any of the TMHE Subsidiaries, unless
         Times Mirror or McGraw-Hill, as the case may be, concludes that
         there is no reasonable basis for such position.  None of
         McGraw-Hill, TMHE or any of the TMHE Subsidiaries shall file
         any amended Tax Returns for any periods for or in respect of
         TMHE or any of the TMHE Subsidiaries with respect to which
         McGraw-Hill is not obligated to prepare or cause to be prepared
         the original of such Tax Returns pursuant to this Section
         12.02, without the prior written consent of Times Mirror. 

                   (d)  Any Taxes for a Straddle Period of TMHE and/or
         the TMHE Subsidiaries shall be apportioned between Times Mirror
         and McGraw-Hill as set forth below in Section 12.05(a).  To the
         extent estimated Taxes have been paid prior to the Closing Date
         or, in the case of Taxes other than Income Taxes, are accrued
         on the Closing Date Balance Sheet with respect to a Pre-Closing
         Tax Period or Straddle Period, Times Mirror's liability with


                                       -91-<PAGE>







         respect thereto shall be reduced by that amount.  Upon timely
         notice from McGraw-Hill, Times Mirror shall pay to McGraw-Hill,
         at least 10 days prior to the date any payment for Taxes as
         described in this Section 12.02 is due, Times Mirror's share of
         such Taxes as described in this Section 12.02.

                   Section 12.03.  Tax Sharing Agreements.  On the Clos-
         ing Date, all Tax sharing agreements and arrangements between
         (i) TMHE or any of the TMHE Subsidiaries, on the one side, and
         (ii) Times Mirror or any of its subsidiaries or affiliates
         (other than TMHE and the TMHE Subsidiaries), on the other side,
         shall be terminated and have no further effect for any taxable
         year or period (whether a past, present or future year or pe-
         riod), and no additional payments shall be made thereunder on
         or after the Closing Date in respect of a redetermination of
         College Publishing Business Tax Liabilities or otherwise.

                   Section 12.04.  Assistance and Cooperation.  After
         the Closing Date, each of Times Mirror and McGraw-Hill shall:

                   (i)  assist in all reasonable respects (and cause
              their respective affiliates to assist) the other party in
              preparing any Tax Returns or reports which such other par-
              ty is responsible for preparing and filing in accordance
              with this Article 12;

                  (ii)  cooperate in all reasonable respects in pre-
              paring for any audits of, or disputes with taxing authori-
              ties, regarding any Tax Returns of TMHE, Mosby, the TMIP
              Entities or any TMHE Subsidiary;

                 (iii)  make available to the other and to any taxing
              authority as reasonably requested all information, rec-
              ords, and documents relating to Taxes of TMHE, Mosby, the
              TMIP Entities and each TMHE Subsidiary;

                  (iv)  provide timely notice to the other in writing of
              any pending or threatened tax audits or assessment of
              TMHE, Mosby, the TMIP Entities and each TMHE Subsidiary
              for taxable periods for which the other may have a li-
              ability under this Article 12 or Article 11; and

                   (v)  furnish the other with copies of all correspon-
              dence received from any taxing authority in connection
              with any tax audit or information request with respect to
              any such taxable period.

         Agreement:

              portion of any Straddle Period ending on the Closing Date
              including any Taxes incurred as a result of making the
              TMHE Elections and any transfer, sales or gains Taxes
              (other than transfer Taxes or sales Taxes based upon the
              value of transferred property and imposed by law on
              McGraw-Hill) arising as a result of the transactions con-
              templated by this Agreement; (y) all liability for Taxes
              of Mosby and the TMIP Entities, whether arising before or

              the Mosby Liabilities and any liability arising out of the
              purchase of the International Assets and the assumption of
              the International Liabilities (other than transfer Taxes
              or sales Taxes based upon the value of transferred prop-
              erty and imposed by law on McGraw-Hill); and (z) all li-

              its Subsidiaries otherwise joins or has ever joined (or is
              or has ever been required to join) in filing any Consoli-

              ever, that College Publishing Business Tax Liabilities
              described above shall be reduced to the extent that the
              aggregate reserves for Taxes (excluding deferred income

              the aggregate liability for Taxes for periods through the

              ending on the Closing Date (the "Pre-Closing Tax Period")
              shall be computed based upon the ratio of the number of
              days in the Pre-Closing Tax Period and the number of days
              in the entire Tax period; and

                   (B)  Taxes of TMHE and the TMHE Subsidiaries for the

              ended as of the close of business on the Closing Date,



                                       -93-<PAGE>







              and, in the case of any Taxes of TMHE and the TMHE Sub-
              sidiaries attributable to the ownership by TMHE or any of

              nership or other "flowthrough" entity (other than the TMHE
              Subsidiaries), as if a taxable period of such partnership
              or the "flowthrough" entity ended as of the close of busi-
              ness on the Closing Date.

                   (b)  "Consolidated Tax Returns" means a Tax Return

              assessment or collection of any Tax or the administration
              of any laws, regulations or administrative requirements

         Straddle Period, McGraw-Hill shall consult with Times Mirror
         with respect to the resolution of any issue that would affect
         Times Mirror, and not settle any such issue, or file any
         amended return relating to any such issue, without the consent
         of Times Mirror, which consent shall not unreasonably be
         withheld.  Where consent to a settlement is withheld by the
         other party pursuant to this Section 12.06, such other party
         may continue or initiate any further proceedings at its own ex-
         pense, provided that the liability of the first party, after


                                       -94-<PAGE>







         giving effect to this Agreement, shall not exceed the liability
         that would have resulted from the settlement or amended return.
         Times Mirror shall furnish McGraw-Hill, TMHE and the TMHE Sub-
         sidiaries with its cooperation in a manner comparable to that
         described in Section 12.04 hereof to effect the purposes of

                           TAX MATTERS RELATING TO THE
                         TRANSFER OF THE SHEPARD'S SHARES

                   Section 12A.01.  Section 338(h)(10) Election.

         timely and irrevocable elections under Section 338(h)(10) of
         the Code and, if permissible, similar elections under any ap-
         plicable state or local income tax laws with respect to the
         transfer of the Shepard's Shares.  McGraw-Hill, Times Mirror
         and Shepard's shall report the transfer of the Shepard's Shares
         consistent with such elections under Section 338(h)(10) of the
         Code or any similar state or local tax provision (the "Shep-
         ard's Elections") and shall take no position contrary thereto
         unless and to the extent required to do so pursuant to a deter-
         mination (as defined in Section 1313(a) of the Code or any
         similar state or local tax provision).

                   (b)  To the extent possible, McGraw-Hill, Times Mir-
         ror and Shepard's shall execute at the Closing any and all
         forms necessary to effectuate the Shepard's Elections (includ-
         ing, without limitation, Internal Revenue Service Form 8023-A
         and any similar forms under applicable state and local income
         tax laws (the "Shepard's Section 338 Forms")).  In the event,
         however, any Shepard's Section 338 Forms are not executed at
         the Closing, McGraw-Hill, Times Mirror and Shepard's shall pre-
         pare and complete each such Shepard's Section 338 Form no later
         than 15 days prior to the date such Shepard's Section 338 Form
         is required to be filed.  McGraw-Hill, Times Mirror and
         Shepard's shall each cause the Shepard's Section 338 Forms to
         be duly executed by an authorized person for McGraw-Hill, Times
         Mirror and Shepard's in each case, and shall duly and timely
         file the Shepard's Section 338 Forms in accordance with ap-
         plicable tax laws and the terms of this Agreement.

                   (c)  The purchase price for the Shepard's Shares
         shall be allocated in accordance with Section 12.01(c) of this

         Returns.  (a)  McGraw-Hill shall be liable for all Taxes of


                                       -95-<PAGE>







         Shepard's for any taxable period that ends on or before the
         Closing Date, including the portion of any Straddle Period end-
         ing on the Closing Date.  McGraw-Hill shall be liable for all
         transfer, sales or gains Taxes arising as a result of the
         transactions contemplated by this Agreement, other than trans-
         fer or sales taxes based upon the value of property transferred
         and which are imposed by law on Times Mirror, which shall be
         paid by Times Mirror.

                   (b)  Times Mirror and McGraw-Hill agree that if
         Shepard's is permitted but not required under applicable state
         or local Tax laws to treat the Closing Date as the last day of
         a taxable period, Times Mirror and McGraw-Hill shall treat such
         day as the last day of a taxable period.

                   (c)  McGraw-Hill shall prepare or cause to be pre-
         pared and timely filed all federal, state, provincial, local
         and foreign Tax Returns in respect of Shepard's, its assets or
         activities that (i) are required to be filed on or before the
         Closing Date or (ii) are required to be filed after the Closing
         Date and (A) are Consolidated Tax Returns or (B) are with re-
         spect to Income Taxes and are required to be filed on a sepa-
         rate Tax Return basis for any tax period ending on or before
         the Closing Date.  McGraw-Hill shall pay all Taxes shown as due
         on such Tax Returns.  Times Mirror shall prepare or cause to be
         prepared and shall file or cause to be filed all other Tax Re-
         turns required of Shepard's or in respect of its assets or ac-
         tivities.  McGraw-Hill shall reimburse Times Mirror for its
         share of the Taxes due with respect to such Tax Returns, in
         accordance with Section 12A.02(a) and (d) hereof.  Any such Tax
         Returns that include periods ending on or before the Closing
         Date or that include the activities of Shepard's prior to the
         Closing Date shall, insofar as they relate to Shepard's, be on
         a basis consistent with past practices for such Tax Returns
         filed in respect of Shepard's, unless McGraw-Hill or Times Mir-
         ror, as the case may be, concludes that there is no reasonable
         basis for such position.  Neither Times Mirror nor Shepard's
         shall file any amended Tax Returns for any periods for or in
         respect of Shepard's with respect to which Times Mirror is not
         obligated to prepare or cause to be prepared the original of
         such Tax Returns pursuant to this Section 12A.02, without the
         prior written consent of McGraw-Hill. 

                   (d)  Any Taxes for a Straddle Period of Shepard's
         shall be apportioned between McGraw-Hill and Times Mirror as
         set forth below in Section 12A.05.  To the extent estimated
         Taxes have been paid prior to the Closing Date or, in the case
         of Taxes other than Income Taxes, are accrued on the Closing
         Date Balance Sheet with respect to a Pre-Closing Tax Period or
         Straddle Period, McGraw-Hill's liability with respect thereto


                                       -96-<PAGE>







         shall be reduced by that amount.  Upon timely notice from Times
         Mirror, McGraw-Hill shall pay to Times Mirror at least 10 days
         prior to the date any payment for Taxes as described in this
         Section 12A.02 is due, McGraw-Hill's share of such Taxes as
         described in this Section 12A.02.

                   Section 12A.03.  Tax Sharing Agreements.  On the
         Closing Date, all Tax sharing agreements and arrangements be-
         tween (i) Shepard's, on the one side, and (ii) McGraw-Hill or
         any of its subsidiaries or affiliates (other than Shepard's),
         on the other side, shall be terminated and have no further ef-
         fect for any taxable year or period (whether a past, present or
         future year or period), and no additional payments shall be
         made thereunder on or after the Closing Date in respect of a
         redetermination of Shepard's Tax Liabilities or otherwise.

                   Section 12A.04.  Assistance and Cooperation.  After
         the Closing Date, each of McGraw-Hill and Times Mirror shall:

                   (i)  assist in all reasonable respects (and cause
              their respective affiliates to assist) the other party in
              preparing any Tax Returns or reports which such other par-
              ty is responsible for preparing and filing in accordance
              with this Article 12A;

                  (ii)  cooperate in all reasonable respects in pre-
              paring for any audits of, or disputes with taxing authori-
              ties, regarding any Tax Returns of Shepard's;

                 (iii)  make available to the other and to any taxing
              authority as reasonably requested all information,
              records, and documents relating to Taxes of Shepard's;

                  (iv)  provide timely notice to the other in writing of
              any pending or threatened tax audits or assessment of
              Shepard's for taxable periods for which the other may have
              a liability under this Article 12A or Article 11; and

                   (v)  furnish the other with copies of all correspon-
              dence received from any taxing authority in connection
              with any tax audit or information request with respect to
              any such taxable period. 

                   Section 12A.05.  Definitions.  For purposes of this
         Agreement, "Shepard's Tax Liabilities" means (x) all liability
         for Taxes of Shepard's for any taxable period that ends on or
         before the Closing Date and the portion of any Straddle Period
         ending on the Closing Date including any Taxes incurred as a
         result of making the Shepard's Elections and any transfer,
         sales or gains Taxes (other than transfer Taxes or sales Taxes


                                       -97-<PAGE>







         based upon the value of transferred property and imposed by law
         on Times Mirror) arising as a result of the transactions con-
         templated by this Agreement; and (y) all liability (as a result
         of Treasury Regulation Section 1.1502-6(a) or otherwise) for
         Taxes of any stockholders of Shepard's or any other Person
         other than Shepard's which is or has ever been affiliated with
         Shepard's, or with whom Shepard's otherwise joins or has ever
         joined (or is or has ever been required to join) in filing any
         Consolidated Return, prior to the Closing Date; provided, how-
         ever, that Shepard's Tax Liabilities described above shall be
         reduced to the extent that the aggregate reserves for Taxes
         (excluding deferred income taxes) reflected on the Closing Date
         Balance Sheet exceeds the aggregate liability for Taxes for
         periods through the Closing Date not previously paid.

                   In the case of any Straddle Period:

                   (A)  the periodic Taxes of Shepard's that are not
              based on income or receipts (e.g., property Taxes) for the
              Pre-Closing Tax Period shall be computed based upon the
              ratio of the number of days in the Pre-Closing Tax Period
              and the number of days in the entire Tax period; and

                   (B)  Taxes of Shepard's for the Pre-Closing Tax Pe-
              riod (other than Taxes described in clause (A)) shall be
              computed as if such taxable period ended as of the close
              of business on the Closing Date, and, in the case of any
              Taxes of Shepard's attributable to the ownership by
              Shepard's of any equity interest in any partnership or
              other "flowthrough" entity, as if a taxable period of such
              partnership or the "flowthrough" entity ended as of the
              close of business on the Closing Date.

                   Section 12A.06.  Controversies.  McGraw-Hill shall
         have the right, at its own expense, to control any Tax Audit,
         initiate any claim for refund, contest, resolve and defend
         against any assessment, notice of deficiency, or other adjust-
         ment or proposed adjustment relating to any and all Taxes for
         any Pre-Closing Tax Period or any period preceding a Pre-
         Closing Tax Period with respect to Shepard's.  Times Mirror
         shall have the right, at its own expense, to control any other
         Tax Audit, initiate any other claim for refund, and contest,
         resolve and defend against any other assessment, notice of de-
         ficiency, or other adjustment or proposed adjustment relating
         to Taxes with respect to Shepard's; provided that, with respect
         to any state and local or foreign Taxes for any Straddle
         Period, Times Mirror shall consult with McGraw-Hill with re-
         spect to the resolution of any issue that would affect McGraw-
         Hill, and not settle any such issue, or file any amended return
         relating to any such issue, without the consent of McGraw-Hill,


                                       -98-<PAGE>







         which consent shall not unreasonably be withheld.  Where con-
         sent to a settlement is withheld by the other party pursuant to
         this Section 12A.06, such other party may continue or initiate
         any further proceedings at its own expense, provided that the
         liability of the first party, after giving effect to this
         Agreement, shall not exceed the liability that would have re-
         sulted from the settlement or amended return.  McGraw-Hill
         shall furnish Times Mirror and Shepard's with its cooperation
         in a manner comparable to that described in Section 12A.04
         hereof to effect the purposes of this Section 12A.06.

              published by the College Publishing Business of TMHE or

              any such returned publications that McGraw-Hill intends to
              retain for resale.  A receivable shall be established on

              printing and binding cost of such returned publications as
              McGraw-Hill intends to retain for resale and all other
              such returned publications shall be destroyed.  McGraw-

                   (uu)  The proviso in Section 10.07(b) is hereby
         amended to read as follows:

                   provided, however, that, in order for any College
                   Publishing Business Transferred Employee to be eli-
                   gible to participate in any College Publishing Busi-
                   ness Post-Retirement Plan, such employee must ex-
                   pressly elect in writing to participate therein


                                       -11-<PAGE>







                   within 31 days following the Closing Date and must
                   elect in writing to commence coverage thereunder
                   either effective as of the Closing Date or effective
                   as of the date of such employee's retirement under
                   the TM Pension Plan, if later.

                   (vv)  The first three sentences of Section 10A.01 are
         hereby amended to read as follows:

                   Except as otherwise provided herein, on the Closing
                   Date, all Shepard's Employees who are then (i) ac-
                   tively employed or (ii) carried on the payroll as a
                   result of being on an authorized leave of absence
                   (other than a short-term or long-term disability
                   leave), family leave or vacation leave (hereinafter,
                   an "Employee-on-Leave") shall be employees of Shep-
                   ard's and Times Mirror (collectively, the "Shepard's
                   Transferred Employees").  Shepard's Employees who are
                   on short-term or long-term disability leave on the
                   Closing Date shall be offered employment with Times
                   Mirror and Shepard's following the expiration of the
                   leave of absence only to the extent that Shepard's or
                   McGraw-Hill was obligated to offer employment to any
                   such employee upon return to work following such
                   leave, and, as of the date of such employee's accep-
                   tance of such offer of employment, such employee
                   shall be deemed a Shepard's Transferred Employee for
                   purposes of this Agreement, subject to the terms and
                   conditions set forth in this Article 10A; provided,
                   however, that Times Mirror or Shepard's shall have no
                   obligation to employ any employee described in this
                   sentence whose leave of absence does not end prior to
                   the first anniversary of the Closing Date.  McGraw-
                   Hill shall retain the obligation to provide worker's
                   compensation, short-term disability, long-term dis-
                   ability and other benefits to any employee described
                   in the previous sentence until such time as such em-
                   ployee becomes a Shepard's Transferred Employee.

                   (ww)  Section 10A.01 is further amended by inserting
         the following at the end thereof:

                   McGraw-Hill shall pay and process the regular payroll
                   for each Shepard's Transferred Employee on the sched-
                   uled payment date for the bi-weekly or monthly pay-
                   roll period that includes the Closing Date (the
                   "Transition Payroll Period").  Times Mirror shall
                   promptly reimburse McGraw-Hill, within five days af-
                   ter receipt of invoice from McGraw-Hill, for the por-
                   tion of the gross employer payroll for the Transition


                                       -12-<PAGE>







                   Payroll Period that relates to periods after the
                   Closing Date, and McGraw-Hill shall promptly remit to
                   Times Mirror, in the manner to be agreed by the par-
                   ties, employee-paid payroll tax withholdings in re-
                   spect of such Shepard's Transferred Employees attri-
                   butable to the portion of the Transition Payroll
                   Period occurring after the Closing Date, which shall
                   be remitted when due by Times Mirror to the appropri-
                   ate governmental taxing authority.  For purposes of
                   the previous sentence, "gross employer payroll" means
                   all gross wages, employer-paid payroll taxes and any
                   other employer-paid amounts.  The portion of the
                   Transition Payroll Period amount that relates to pe-
                   riods after the Closing Date and that is paid by
                   Times Mirror to McGraw-Hill shall be ignored for pur-
                   poses of the Post-Closing Adjustment and shall not be
                   included in the change in the intercompany balance
                   between Shepard's and McGraw-Hill for the period from
                   July 1, 1996 through the Closing Date.

                   (xx)  Clause (i) of the second sentence of Section
         10A.07(b) is hereby amended to read as follows:

                   (i)  Shepard's Transferred Employees who, as of the
                   Closing Date, (a) have either been credited with at
                   least ten years of service under the applicable Shep-
                   ard's Post-Retirement Plan and attained at least age
                   55 or have been credited with at least twenty years
                   of service under the applicable Shepard's Post-
                   Retirement Plan and have attained age 50 and (b) are
                   otherwise eligible for benefits under the terms of
                   the applicable Shepard's Post-Retirement Plan,

                   (yy)  The proviso in Section 10A.07(b) is hereby
         amended to read as follows:

                   provided, however, that, in order for any Shepard's
                   Transferred Employee to be eligible to participate in
                   any Shepard's Post-Retirement Plan, such employee
                   must expressly elect in writing to participate there-
                   in within 31 days following the Closing Date and must
                   elect in writing to commence coverage thereunder ef-
                   fective as of the Closing Date.

                   (zz)  The final sentence of Section 12.06 is hereby
         amended to read as follows:

                   Times Mirror, McGraw-Hill, Shepard's, TMHE and the
                   TMHE Subsidiaries shall cooperate with one another in
                   a manner comparable to that described in Section


                                       -13-<PAGE>







                   12.04 hereof to effect the purpose of this Section
                   12.06.

                   (aaa)  The final sentence of Section 12A.06 is hereby
         amended to read as follows:

                   Times Mirror, McGraw-Hill, Shepard's, TMHE and the
                   TMHE Subsidiaries shall cooperate with one another in
                   a manner comparable to that described in Section
                   12A.04 hereof to effect the purpose of this Section
                   12A.06.

                   (bbb)  The last two paragraphs of Schedule 4.02(a)(v)
         are hereby amended to read as follows:

                         For purposes of computing the Post-Closing Ad-
                   justments described in Section 9.01(a) hereof, the
                   adjustment described above with respect to reserves
                   for uncollectible accounts and returns will be
                   treated as a pre-June 30, 1996 entry.  As a result,
                   the pro-forma June 30, 1996 unaudited balance sheet
                   or statement of assets conveyed and liabilities as-
                   sumed, as the case may be, of TMHE and Mosby College
                   Text Business will reflect their appropriate share of
                   this adjustment.

                         TMIP has other assets which will be transferred
                   to Buyer under the purchase agreements ("other TMIP
                   assets").  These assets consist of third party li-
                   cense agreements, prepaid expenses, and inventory
                   relating to indigenous works, including work in prog-
                   ress.  There are various liabilities relating to the
                   other TMIP assets recorded on the books of TMIP, in-
                   cluding payables and royalties payable.  The other
                   TMIP assets and the related liabilities will be sold
                   to TMHE prior to the Closing and will therefore be
                   sold to Buyers upon Closing.

                   (ccc)  Schedule 10A.04 is hereby amended and updated
         to read as set forth in Annex A to this Amendment.

                   (ddd)  Schedule 2.02(a)(i) is hereby amended to read
         as set forth in Annex B to this Amendment.

                   (eee)  Schedule 5.03 is hereby amended to read as set
         forth in Annex C to this Amendment.

                   (fff)  Schedule 5.13(a) is hereby amended to read as
         set forth in Annex D to this Amendment.

         as set forth in Annex E to this Amendment.

                   (iii)  Schedule 5.15(k) is hereby amended by replac-

         G to this Amendment.

                   (jjj)  Schedule 5.15(l) is hereby amended to replace
         the first page thereof to read as set forth in Annex H to this
         Amendment.

                   (kkk)  Schedule 5.17(a) is hereby amended by
         replacing tabs (A) and (B) as set forth in Annex I to this
         Amendment.

         the first page thereof to read as set forth in Annex J to this
         Amendment.

                   (mmm)  Schedule 10.01(a) is hereby updated, as pro-
         vided in Section 10.01(a), to replace Schedule 10.01(a) to read

         ment.

                   (ppp)  Schedule 6.14(a) is hereby amended to read as
         set forth in Annex N to this Agreement.

                   3.    The parties agree that a full financial clos-
         ing, with appropriate cut-off procedures, is to be planned,
         executed and documented.  Because the agreed-upon closing date
         occurs on a date other than a fiscal month-end, the parties,
         acknowledging that certain expenses and revenues are typically
         budgeted and recorded on a full-fiscal-month basis, agree to
         the following in an effort to facilitate the preparation of the
         Closing Date financial statements and to ensure that the finan-
         cial statements for Shepard's, TMHE and Mosby are prepared on a
         common, consistent basis:




                                       -15-<PAGE>







              I.  Certain expenses can be prorated for the period Octo-
         ber 1 - October 15 as a percentage of the full month October
         amounts.  The percentage to apply to the full fiscal month Oc-
         tober amounts to calculate the amount for the period October 1
         - 15 is either of the following two formulas:

         Apportionment Method A.  The percentage is calculated as:
         (Revenues for October 1 - 15) / (October fiscal month revenues)
         (revenues for purposes of this apportionment are defined as
         operating revenues inclusive of the provision for sale re-
         turns);

                   or

         Apportionment Method B.  The percentage is calculated as:
         (Business days for October 1 - 15) / (October fiscal month
         business days).

         The parties agree as follows:

                                          Shepard's     TMHE and Mosby

              (All other payrolls -- hourly, weekly, etc. -- will be
         cut-off on an actual basis)

              II.  Revenue for subscription products will be prorated
         for the period October 1 - October 15 as a percentage of the
         full month revenue amount.  The percentage is to be calculated
         as:  (Business days for October 1 - October 15) / (October fis-
         cal month business days).



                                       -16-<PAGE>







              III.  All cash, intercompany accounts, accounts receiv-
         able, accounts payable and other balance sheet account cut-offs
         are to be executed and documented on a full closing basis, ex-
         cept that balance sheet accounts should reflect apportionment
         amounts if called for by paragraph I.  For all revenue (other
         than revenue for subscription products) and for all expenses
         (other than those prorated in accordance with paragraph I),
         cut-offs are to be executed and documented on a full closing
         basis.

         All standard account reconciliations and audit-verifiable docu-
         mentation is to be prepared for the mid-month closing.  All
         revenues and expenses for October, through the Closing, includ-
         ing monthly amounts prorated pursuant to paragraphs I and II,
         shall be computed in a manner consistent with prior practice
         and without regard to any revaluations resulting from the Ex-
         change.

                   4.   Times Mirror represents to McGraw-Hill that (i)
         notwithstanding the statement to the contrary in the notes to
         the TMHE financial statements set forth in Schedule 5.09(a),
         such statements did not include incremental editorial and pro-
         duction expense of $666,000 and incremental plant amortization
         expense of $1,074,000 and (ii) the absence of such amounts was
         offset by the overstatement of certain other inventory related
         costs.

                   5.   No Effect on Consistent Terms.  All terms of the
         Agreement not inconsistent with this Amendment shall remain in
         place and in full force and effect and shall be unaffected by
         this Amendment.

                   6.   Headings.  The headings contained in this Amend-
         ment are inserted for convenience of reference only and shall
         not affect the meaning or interpretation of this Amendment.

                   7.   Counterparts.  This Amendment may be executed in
         one or more counterparts, all of which shall be considered one
         and the same agreement, and shall become effective when one or
         more counterparts have been signed by each party hereto and
         delivered to the other party.

                                       FOR IMMEDIATE RELEASE (23SW--070396)

                     THE MCGRAW-HILL COMPANIES AGREES TO ACQUIRE
                         TIMES MIRROR HIGHER EDUCATION GROUP
                       IN EXCHANGE FOR SHEPARD'S/MCGRAW-HILL 
                                  LEGAL PUBLISHING

                    ACQUISITION OF ESTABLISHED COLLEGE PUBLISHER 
                          IN MAJOR DISCIPLINES REINFORCES 
                          CORPORATION'S GROWTH STRATEGY AND
                           EDUCATIONAL LEADERSHIP POSITION

         NEW YORK, N.Y. -- July 3, 1996 -- In a move that will establish it
         as the world's largest educational publisher, The McGraw-Hill Com-
         panies (NYSE: MHP) announced today it had signed an exchange
         agreement to acquire the Times Mirror Higher Education Group, the
         fourth largest college publisher in the U.S.

         In return for acquiring The Times Mirror Higher Education Group,
         which had 1995 revenues of $228.2 million, The McGraw-Hill Compa-
         nies will trade its Shepard's/ McGraw-Hill legal publishing unit
         to The Times Mirror Company, and will also receive additional un-
         disclosed consideration.  It is anticipated the transaction will
         be completed in the fall, subject to obtaining necessary govern-
         ment approvals as required under the Hart-Scott-Rodino Act.

         The Times Mirror Higher Education Group possesses a talented em-
         ployee team, a rich resource of intellectual property and an out-
         standing record of growth.  The group is comprised of five well-
         known business units:  Richard D. Irwin, Wm. C. Brown, Brown &
         Benchmark, Irwin Professional Publishing and Mosby College.
         Through this acquisition, The McGraw-Hill Companies will
         strengthen its Educational and Professional Publishing business
         segment, and leverage its prowess in international marketing and
         electronic custom publishing.  The McGraw-Hill Companies will be a
         leader in 12 higher education disciplines, including economics,
         accounting, finance, biology and psychology.

         "This acquisition reinforces The McGraw-Hill Companies' global
         growth strategy to build on our current strengths in order to
         achieve long-term, double-digit profit growth.  College publishing
         is a promising segment which offers us significant opportunities,"
         said Joseph L. Dionne, chairman and chief executive officer.  "Ad-
         ditionally, consistent with our growth strategy, we will divest
         businesses where we cannot be among the leaders.  Accordingly, due
         to recent consolidation in legal publishing, it is an appropriate
         time to divest Shepard's/McGraw-Hill, and provide this fine busi-
         ness and its dedicated employees the best opportunity for future
         success."<PAGE>







         "By acquiring the Times Mirror Higher Education Group, we expect
         to generate significant revenue and profit growth through interna-
         tional expansion, database marketing, and other synergies between
         the two organizations," said Harold McGraw III, president and
         chief operating officer.  "This acquisition fits exceptionally
         well with our core strengths, and our future direction for growth
         through international expansion." 

         Peter Jovanovich, president, Educational and Professional Publish-
         ing Group, said, "With little product overlap of its rich base of
         titles, this acquisition allows us to further expand our strong
         international presence and leverage existing innovative technology
         investments, and increase our custom publishing capabilities
         through an increased product line."  He added, "We are fortunate
         to be joining forces with such a talented group of people with an
         outstanding track record of performance.  We are looking forward
         to this larger McGraw-Hill higher education company becoming the
         preeminent higher education publisher in the world."

         The Times Mirror Higher Education Group publishes some of the
         leading and most impressive titles in the college business today.
         Unmatched in history, quality and sell-through ability are publi-
         cations such as:  Larson's Fundamental Accounting Principles;
         Perreult's Basic Marketing; Ross' Fundamentals of Corporate Fi-
         nance; Hole's Human Anatomy & Physiology; Mader's Biology and Hu-
         man Biology; Raven and Johnson's Biology; Santrock's Adolescence
         and Lifespan Development, and others.

         Completion of the transaction is subject to obtaining the neces-
         sary government approvals.

         The McGraw-Hill Companies is a leading information services pro-
         vider meeting worldwide needs in education, business, finance, the
         professions and government.  Founded in 1888, the Corporation to-

         its rich portfolio of valuable brands.  Sales in 1995 exceeded

                        THE McGRAW-HILL COMPANIES REPORTS
                     8.2% INCREASE IN THIRD QUARTER EARNINGS

                       COMPLETES EXCHANGE OF SHEPARD'S FOR
                       TIMES MIRROR HIGHER EDUCATION GROUP

                ACQUISITION ESTABLISHES THE MCGRAW-HILL COMPANIES
                     AS WORLD'S LARGEST EDUCATIONAL PUBLISHER


         NEW YORK, N.Y., OCTOBER 16, 1996  -- The McGraw-Hill Companies

         (NYSE: MHP) today reported that net income for the third quar-

         ter increased by 8.2% to $114.5 million while revenue grew 4.9%

         to $949 million.  Earnings per share were $1.15 compared to

         $1.06 for the same period last year.


                   For the first nine months, net income grew 8.8% to

         $187.9 million.  Revenue for the period was $2.2 billion, an

         increase of 2.7%.  Earnings per share for the first nine months

         were $1.88 versus $1.73 for the comparable period a year ago.


                   The McGraw-Hill Companies also announced the comple-

         tion of the exchange of its Shepard's/McGraw-Hill legal pub-

         lishing unit for the Times Mirror Higher Education Group and

         other consideration, including an undisclosed amount of cash.


                   THIRD QUARTER RESULTS:  "Keys to our third quarter

         were the strong performance of Financial Services and good re-

         sults in the school market despite an off-adoption year," said<PAGE>







         Joseph L. Dionne, chairman and chief executive officer of The

         McGraw-Hill Companies.


                   EDUCATION AND PROFESSIONAL PUBLISHING:  "Operating

         profit increased 4.9% on a revenue gain of 5.4% in this segment

         for the third quarter.


                   "Although comparisons were difficult after an out-

         standing 1995 adoption year in the school market, our

         elementary-high school operations still produced gains this

         year. We had outstanding results in the secondary school and

         supplemental markets, showing strength in both the open ter-

         ritories and in adoption states.  We were also encouraged by

         the early sales of our new basal reading program, Spotlight on

         Literacy, in the open territories.  Spotlight on Literacy is

         currently up for adoption in California, which may spend as

         much as $300 million on new reading programs starting in 1997.


                   "We also benefited from continuing improvement in our

         college division, which had strength in the front and back

         lists and in Primis Custom Publishing sales.


                   "In international markets, we had excellent results

         in Spain with a major new program for secondary schools, but

         improvement there and in Asia could not offset the slow pace of

         recovery in Mexico.  As a result, total international sales

         were flat for the third quarter and profits declined.  Without



                                         -2-<PAGE>







         the shortfall in Mexico, total international sales and profits

         would have been ahead of last year for the third quarter.

         There was also softness in professional book operations.


                   FINANCIAL SERVICES:  "Global growth, new products and

         a strong market for asset-backed securities contributed to the

         10.9% increase in operating profits on a 8.2% gain in revenue

         for this segment in the third quarter.


                   "Standard & Poor's Ratings Services showed strength

         across its entire product lineup.  International and structured

         finance businesses were particularly strong.  Other factors

         were the increased issuance of high yield corporate debt, im-

         proved share in the public finance market and gains in the in-

         surance ratings business both here and abroad.


                   "Our around-the-clock global information businesses

         continued to produce growth at Standard & Poor's Financial In-

         formation Services.  Platt's, our commodities information ser-

         vice in the energy market, and MMS International, which pro-

         vides analysis and information for global debt and currency

         markets, both grew over third-party networks.  But there was

         softness in the secondary municipal market and at DRI.


                   INFORMATION AND MEDIA SERVICES:  "Revenue advanced by

         less than 1% and operating profits declined by 17.3% in this

         segment for the third quarter.



                                         -3-<PAGE>








                   "Improved results at Business Week, Aviation Week and

         our healthcare publications could not overcome the shortfalls

         at BYTE and LAN Times, our computer and communications publica-

         tions, Broadcasting and in the Construction Information Group.


                   "Revenue improved for the Construction Information

         Group, but development and marketing costs for launching the

         windows version of Dodge DataLine and weakness in the construc-

         tion publications contributed to a drop in operating profits.

         "Despite stronger than expected political advertising, the

         Broadcasting Company's revenue and operating profits declined,

         reflecting competition from the Summer Olympics on a rival net-

         work.


                   "Business Week's revenue and profits both grew, pri-

         marily driven by improvements in circulation revenue.


                   THE OUTLOOK:  "There are signs of improvement in our

         construction information group and some of our key advertising-

         based businesses for the fourth quarter.  Political advertising

         is strengthening at our television stations and momentum is

         starting to build at Business Week.  Financial Services contin-

         ues to show strength.  Excluding the impact of the swap for the

         Times Mirror properties, we believe we will achieve our growth

         objectives for the year.

                   "The exchange of the Shepard's/McGraw-Hill legal pub-

         lishing unit for the Times Mirror Higher Education Group will

         be a factor in the fourth quarter.  We expect a pre-tax gain,

         net of one-time charges, of more than $300 million.  Dilution

         in fourth quarter earnings is estimated to be five-to-seven

         cents per share, excluding one-time charges, due to the typical

         seasonal decline in higher education business' earnings and the

         timing of integration savings.


                   "The acquisition of the Times Mirror Higher Education

         Group makes The McGraw-Hill Companies the world's largest edu-

         cational publisher and the leader in 12 higher education disci-

         plines, including accounting, economics, finance, biology and

         psychology.  The new product lineup significantly increases our

         sales opportunities overseas where The McGraw-Hill Companies

         already has a significant presence."


                   "The new acquisition represents another step in our

         strategy of building on our strength in global publishing,"

         said Harold McGraw III, president and chief operating officer

         of The McGraw-Hill Companies.  "There is very little product

         overlap, and we will gain some significant operating efficien-

         cies by integrating the Times Mirror Higher Education Group

         with our own operations."







                                         -5-<PAGE>







                   The acquisition involves approximately 1,000 employ-

         ees mainly located in Dubuque, Iowa, Madison, Wis., Burr Ridge,

         Ill., St. Louis, Mo., and Guilford, Conn.


                   The five Times Mirror Higher Education business units

         that have been acquired --Richard D. Irwin, William C. Brown,

         Brown & Benchmark, Irwin Professional Publishing and Mosby Col-

         lege -- will become part of The McGraw-Hill CompaniesO new

         Higher Education and Consumer Group, headed by Robert E. Evan-

         son.  The William C. Brown printing operation was sold to Que-

         becor Printing (USA) Corp.
