ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.

GENERAL

          Immediately before midnight on October 15, 1996, The Times Mirror
Company (the "Company") consummated the transactions (the "Exchange") described
below which resulted in the acquisition by the Company of all of the common
stock of Shepard's/McGraw-Hill, Inc. ("Shepard's") from The McGraw-Hill
Companies, Inc. ("McGraw-Hill"), in exchange for all of the stock of The Times
Mirror Higher Education Group, Inc. ("TMHEG") and certain additional
consideration described below.

          In addition, the Company assigned certain contract rights under the
Exchange Agreement described below to Shepard's and caused Shepard's to assign
those contract rights and to contribute all of its assets to a partnership
established by Shepard's and a newly formed, wholly owned subsidiary of
Shepard's.  Subject to the completion of a pending regulatory review, the
Company expects in the near future to sell a 50% interest in such partnership to
Reed Elsevier Inc. ("REI") and an affiliate of REI.

          On October 16, 1996, the Company issued a press release (the "Press
Release") announcing the completion of the Exchange.

THE EXCHANGE -- ACQUISITION OF THE SHEPARD'S SHARES AND DISPOSITION OF THE TMHEG
SHARES AND CERTAIN ASSETS OF MOSBY AND TMIP

          In early 1996, management of the Company considered various strategic
alternatives with respect to TMHEG, and in March the Board of Directors of the
Company authorized management to proceed with its plan for the sale or exchange
of TMHEG.  Management identified and contacted several potential bidders,
including McGraw-Hill, about a possible sale and/or exchange of assets, and
engaged Morgan Stanley & Co. Incorporated as its financial advisor for an
auction process beginning in April.  In June, the Board of Directors authorized
management to continue to negotiate with the bidders, in one or more related or
unrelated transactions, the sale of all of the outstanding common stock and all
or a portion of the assets of TMHEG as well as certain assets of Mosby and TMIP
for consideration in the form of cash, assets 

                                       3
<PAGE>
 
or a combination of cash and assets, and also authorized management to negotiate
purchase or exchange agreements with respect to such sale. After evaluating bids
from several parties, management of the Company determined that McGraw-Hill
presented the most favorable possibility for an exchange of assets which would
meet the strategic interests of the Company.

          The Company signed an Exchange Agreement dated as of July 3, 1996 (the
"Exchange Agreement") by and among the Company, Mosby and McGraw-Hill, pursuant
to which (1) McGraw-Hill agreed to sell to the Company all of the Shepard's
Shares; (2) the Company agreed to sell to McGraw-Hill all of the TMHEG Shares;
(3) Mosby agreed to sell to McGraw-Hill certain assets described in the Exchange
Agreement (the "Mosby Assets") devoted solely to Mosby's college-level life and
physical science text publishing business ("Mosby's College Text Business"), and
McGraw-Hill agreed to assume certain liabilities of Mosby described in the
Exchange Agreement (the "Mosby Liabilities") relating to Mosby's College Text
Business; (4) the Company agreed to cause TMIP, its direct and indirect
subsidiaries and Times Mirror Singapore Pte. Ltd. (the "TMIP Entities") to sell
to McGraw-Hill all of the interest of the TMIP Entities in certain assets
described in the Exchange Agreement (the "International Assets"), and McGraw-
Hill agreed to assume certain liabilities of the TMIP Entities described in the
Exchange Agreement (the "International Liabilities"); and (5) the Company agreed
to make a cash payment of $25 million to McGraw-Hill and made certain
commitments to McGraw-Hill related to the real estate assets of Irwin in an
amount not to exceed $10.5 million.

          The Company, Mosby and McGraw-Hill signed the Amendment to Exchange
Agreement (the "Amendment"), dated as of October 15, 1996, which clarified
certain provisions of the Exchange Agreement, provided for the transfer of the
International Assets and the International Liabilities by the TMIP Entities to
TMHEG prior to the closing of the Exchange, and made certain other changes
required by a mid-month closing of the Exchange.

CONSIDERATION FOR THE EXCHANGE

          Immediately before midnight on October 15, 1996, the Company
transferred all of the TMHEG Shares and the Mosby Assets to McGraw-Hill, made a
cash payment of $25 million (less certain adjustments) to McGraw-Hill, and
confirmed certain commitments to McGraw-Hill related to the real estate assets
of Irwin in an amount not to exceed $10.5 million, in exchange for all of the
Shepard's Shares and the assumption by McGraw-Hill of the Mosby Liabilities.
Certain post-closing adjustments in the purchase price will be made pursuant to
the terms of the Exchange Agreement and the Amendment.

          The source of funds for the cash portion of the consideration paid by
the Company for the acquisition of the Shepard's Shares was short-term
borrowings by the Company.

CREATION OF SHEPARD'S COMPANY

          Immediately after the closing of the Exchange, the Company assigned
its indemnification rights and certain other contractual rights under the
Exchange Agreement to Shepard's as a contribution to capital.  The Company then
caused Shepard's to contribute all of its assets and to assign the contractual
rights to a general partnership called Shepard's Company.  TM ShepCo Inc., a
wholly owned subsidiary of Shepard's, was also formed immediately after the
closing of the Exchange and is the other general partner of Shepard's Company.
Subject to the completion of a pending regulatory review, REI and its wholly
owned subsidiary Reed Books Inc. are expected to purchase partnership interests
aggregating 50% in Shepard's Company.

          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, possesses
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 business 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 condition or results of operations of
TMHE or the TMHE Subsidiaries 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 certificates 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, return or redeem any shares of capital stock or other
securities of TMHE, and no equity securities of TMHE are reserved for issuance
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
understanding restricting or otherwise relating to the voting, dividend 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
contemplated by Article 2, good and marketable title to the TMHE Shares will
pass to McGraw-Hill, free and clear of any mortgages, liens, claims,
encumbrances, security interests, options, 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 subject 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 interests.

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

business;

          (b)  during the Restricted Period, Times Mirror and its Affiliates

Neither the Mosby Assets nor the International Assets will include any account

- ---------------------------                           
pay to each College Publishing Business Transferred Employee all retention or
stay-pay and performance bonuses payable, including those payable under the

Investment Plan con templated in Schedule 10.04.  Such contribution shall be

                      ----------------------
to the Closing Date, Times Mirror shall assume  

                                     -75-
<PAGE>
 
unconditionally from TMHE the sponsorship of the Brown and Probus Plans,
including, without limitation, the obligation to pay all benefits contemplated

shall cause the interests of all College Publishing Business Transferred
Employees in the Brown and Probus Plans and the Times Mirror Savings Plus Plan

practicable following the Closing 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 Transferred 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
reasonably 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; provided, 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 contribution 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 Employees 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 College Publishing
Business Transferred Employees who were covered by the TM Pension Plan
immediately prior to the Closing Date

                                     -76-

TMHE Subsidiaries 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.

          (b)  In connection with McGraw-Hill's obligation to provide welfare
benefits to the eligible College Publishing Business Transferred Employees under

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

                              --------  -------
Publishing Business 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 retirement date with McGraw-Hill.

          (c)  With respect to any welfare benefit plans maintained at the TMHE

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.

          (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 reimburse covered Shepard's 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 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 Replacement 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 any other provision herein to the contrary, McGraw-Hill will

Post-Retirement Plan, such employee must expressly elect to participate therein
as of his retirement date with Times Mirror or the College Publishing Business.

          (c)  With respect to any welfare benefit plans maintained at
Shepard's level, Times Mirror and McGraw-Hill 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 Shepard's for eligible Shepard's Transferred Employees.

          (d)  For purposes of this Section 10A.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.

years following the Closing Date:

          (a)  Times Mirror shall indemnify and hold McGraw-Hill harmless from

     to honor any obligation expressly assumed under this Article 10A by Times
     Mirror or a breach by Times Mirror of any covenant of Times Mirror set
     forth in this Article 10A and (ii) any actions taken by Times Mirror with

the indemnifying party, within 5 Business Days after the indemnified party'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 defense 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 assumed 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 prosecution 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 reasonably
relevant to such Third-Party Claim, and making employees available on a mutually
convenient basis to provide additional

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 party's
prior written consent (which consent shall not be unreasonably 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.

                          ---------------------------   
McGraw-Hill shall jointly make timely and irrevocable elections under Section
338(h)(10) of the Code and, if permissible, similar elections under any
applicable state or local income tax laws with respect to the transfer of the

TMHE and the TMHE Subsidiaries shall report the transfer of the TMHE Shares and
the shares of the TMHE Subsidiaries consistent with such elections under
Section 338(h)(10) of the Code or any similar state or local tax provision (the
"TMHE Elections") and shall take no position contrary thereto unless and to the
 --------------      
extent required to do so pursuant to a determination (as defined in Section

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 Election for purposes of this Agreement.

execute at the Closing any and all forms necessary to effectuate the TMHE

<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 applicable 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 Appraiser 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 allocation 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 12.02.  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

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 prepared and timely
filed all federal, state, provincial, local and foreign Tax Returns in respect
of TMHE and the TMHE Subsidiaries, 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 Returns. McGraw-Hill

other Tax Returns required of TMHE and the TMHE Subsidiaries, or in respect of
their assets or activities. Times Mirror shall reimburse McGraw-Hill for its
share of the Taxes due with respect to such Tax Returns, in accordance with

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 re spect 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.

     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:

"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-

based upon the value of transferred property and imposed by law on Times Mirror)
arising as a result of the transactions contemplated 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,
                                                                    --------
however, 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 Period (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
                           -------------

contest, resolve and defend against any assessment, notice of deficiency, or
other adjustment 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 deficiency, or other
adjustment or proposed adjustment relating to Taxes with respect to Shepard's;

Straddle Period, Times Mirror shall consult with McGraw-Hill with respect 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-

which consent shall not unreasonably be withheld.  Where consent 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 resulted 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.

               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 therein within 31 days following the Closing Date and
               must elect in writing to commence coverage thereunder effective
               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

               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 Adjustments
               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 assumed, 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 license agreements, prepaid expenses, and
               inventory relating to indigenous works, including work in
               progress. There are various liabilities relating to the other
               TMIP assets recorded on the books of TMIP, including 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

               3.    The parties agree that a full financial closing, 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 financial 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 October 1 -October 15
as a percentage of the full month October amounts.  The percentage to apply to
the full fiscal month October 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 returns);

          or

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

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 fiscal month business days).

     III.  All cash, intercompany accounts, accounts receivable, accounts
payable and other balance sheet account cut-offs are to be executed and
documented on a full closing basis, except 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 documentation is to be
prepared for the mid-month closing.  All revenues and expenses for October,
through the Closing, including 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 Exchange.

          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 production 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 Amendment are inserted
              --------

interpretation of this Amendment.

          7.  Counterparts.  This Amendment may be executed in one or more

For Immediate Release


                   Times Mirror Announces Completion of Sale
             of Higher Education Group to The McGraw-Hill Companies


     LOS ANGELES, CALIFORNIA, October 16, 1996 -- The Times Mirror Company
announced today that it has completed its acquisition of Shepard's, the nation's
premier legal citation service, from The McGraw-Hill Companies in exchange for
the Times Mirror Higher Education Group and additional undisclosed
consideration. Times Mirror expects to report a small gain on the exchange net
of special charges related to the transaction.

     The previously announced formation of a partnership with Reed Elsevier to
jointly own Shepard's will follow the completion of a currently pending
regulatory review of the transaction. This process is expected to be
successfully completed in the near future.

     "We are delighted to begin our relationship with Shepard's," said Kathryn
M. Downing, president and chief executive officer, Matthew Bender & Co. Inc.
"Shepard's outstanding product mix of Federal and State jurisdictional and
topical Citator services substantially strengthens the scope of legal research
tools which we will now offer our customers." Shepard's will be managed by
Matthew Bender, reporting to Downing, pending the formation of the joint venture
with Reed Elsevier.

     The acquisition of Shepard's is an important step in broadening the mix of
legal information which Bender provides its customers. Earlier this year Times
Mirror and Reed Elsevier entered into a long-term cross-license agreement to
offer Matthew Bender publications online through LEXIS service and to provide a
significant portion of the LEXIS caselaw database through Matthew Bender's print
and CD-ROM products. Times Mirror and Reed Elsevier expect to pursue other
opportunities together.
