                                                                             5

     (f) Not applicable.

Item 3.   Source and Amount of Funds or Other Consideration.

     Merger Sub paid for the shares of Houghton Mifflin Common Stock that were
tendered pursuant to the Tender Offer through capital contributions and loans
that were made by Vivendi Universal. Vivendi Universal had sufficient cash on
hand to make the capital contributions and loans and did not rely on
borrowings. The amount of funds used in making the purchases was
$1,636,896,326.24.

Item 4.   Purpose of Transaction.

     (a)-(b) The purpose of the Tender Offer was to enable Vivendi Universal
to acquire control of Houghton Mifflin and to acquire the outstanding shares
of Houghton Mifflin Common Stock. The Tender Offer, as the first step in the
acquisition of Houghton Mifflin, was intended to facilitate the acquisition of
all the outstanding shares of Houghton Mifflin Common Stock.

     On June 1, 2001, Vivendi Universal, Houghton Mifflin, and Merger Sub
entered into an Agreement and Plan of Merger (the "Merger Agreement").
Pursuant to the Merger Agreement and the actions contemplated therein, Merger
Sub will be merged with and into Houghton Mifflin (the "Merger"), with
Houghton Mifflin continuing as the surviving corporation and as a wholly owned
subsidiary of Vivendi Universal. Upon completion of the Merger, each issued
and outstanding share of Houghton Mifflin Common Stock will be exchanged for
the right to receive $60.00 per share, net to the seller in cash, without
interest thereon. The purpose of the Merger is to acquire all outstanding
shares of Houghton Mifflin common stock not tendered and purchased pursuant to
the Tender Offer or otherwise.

     The Merger is subject to certain conditions. The descriptions of the
Merger Agreement contained herein are qualified in their entirety by reference
to such agreement, which is incorporated by reference herein as Exhibit 2.

     The information set forth under the caption "Purpose of the Offer; the
Merger Agreement; Plans for the Company" in the Offer to Purchase is
incorporated herein by reference.

     (c) While Vivendi Universal and Merger Sub reserve the right to take or
recommend such action as they may consider desirable in light of their ongoing
review of the businesses and operations of Houghton Mifflin, neither Vivendi
Universal nor Merger Sub has any present plans or proposals which relate to or
would result in the sale or transfer of a material amount of assets of
Houghton Mifflin.

     (d) Pursuant to the Merger Agreement, upon purchase of shares of Houghton
Mifflin Common Stock pursuant to the Tender Offer and from time to time
thereafter, Vivendi Universal shall be entitled to designate a number of
directors of Houghton Mifflin, rounded down to the next whole number, as is
equal to the product of the total number of directors on Houghton Mifflin's
Board of Directors (giving effect to the directors designated by Vivendi
Universal pursuant to this sentence) multiplied by the Board Fraction. "Board
Fraction" means a fraction, the numerator of which shall be the number of
shares of Houghton Mifflin Common Stock that Vivendi Universal and its
subsidiaries beneficially own at the time of calculation of the Board
Fraction, and the denominator of which shall be the total number of shares of
Houghton Mifflin Common Stock then outstanding. Pursuant to the Merger
Agreement, Houghton Mifflin has agreed promptly to take such actions as are
necessary to enable such designees of Houghton Mifflin to be elected or
appointed to Houghton Mifflin's Board of Directors. Until the effective time
of the Merger, Houghton Mifflin's Board of Directors shall have at least two
directors of Houghton Mifflin who are directors on the date of the Merger
Agreement and who are not affiliates of Vivendi Universal or Merger Sub (the
"Independent Directors").

     The Independent Directors shall form a committee that, during the period
from the time shares of Houghton Mifflin Common Stock are purchased pursuant
to the Tender Offer until the effective time of the Merger, shall have the
sole power and authority, by a majority vote of such Independent Directors,
for Houghton Mifflin to (i) amend or terminate the Merger Agreement or to
extend the time for the performance of any of the obligations or other acts of
Vivendi Universal or Merger Sub under the Tender Offer, the Merger or the
Merger Agreement, (ii) exercise or waive any of Houghton Mifflin's rights,
benefits or remedies under the Merger Agreement, or (iii) take any other
action under or in connection with the Merger Agreement if such action
materially and adversely affects holders of Houghton Mifflin Common Stock
other than Vivendi Universal or Merger Sub.





                                                                             6

     The information set forth under the caption "Purpose of the Offer; the
Merger Agreement; Plans for the Company" in the Offer to Purchase is
incorporated herein by reference.

     Vivendi Universal intends to designate some or all of the directors it is
permitted to designate under the Merger Agreement prior to the effective time
of the Merger.

     (e) Other than as a result of the Merger described in Item 4 above, upon
consummation of the Merger, the articles of organization of Houghton Mifflin
shall be amended so that the total number of shares of all classes of stock
which Houghton Mifflin shall have authority to issue is 1,000 shares of common
stock, par value $1.00 per share.

     While Vivendi Universal and Merger Sub reserve the right to take or
recommend such action as they may consider desirable in light of their ongoing
review of the businesses and operations of Houghton Mifflin, neither Vivendi
Universal nor Merger Sub has any present plans or proposals which relate to or
would result in any material change in the dividend policy of Houghton
Mifflin.

     (f) Upon consummation of the Merger, Houghton Mifflin's business will
continue to be conducted in its current corporate form but as a wholly owned
subsidiary of Vivendi Universal. Various corporate, administrative and
departmental functions of Houghton Mifflin may be consolidated with those of
Vivendi Universal and its subsidiaries. While Vivendi Universal and Merger Sub
reserve the right to take or recommend such action as they may consider
desirable in light of their ongoing review of the businesses and operations of
Houghton Mifflin, neither Vivendi Universal nor Merger Sub has any present
plans or proposals which relate to or would result in any other material
changes in Houghton Mifflin's business or corporate structure.

     (g) Upon consummation of the Merger, the articles of organization of
Houghton Mifflin shall be amended so that Section 3 of such restated articles
of organization reads in its entirety as follows: "The total number of shares
of all classes of stock which the Corporation shall have authority to issue is
1,000 shares of common stock, par value $1.00 per share." Upon consummation of
the Merger, the By-laws of Houghton Mifflin, as in effect immediately prior to
the Merger, shall be the By-laws of Houghton Mifflin until thereafter changed
or amended as provided therein or by applicable law.

     (h)-(i) Upon consummation of the Merger, the Houghton Mifflin Common
Stock will be delisted from the New York Stock Exchange and will become
eligible for termination of registration pursuant to Section 12(g)(4) of the
Exchange Act.

     (j) Other than as described above, Vivendi Universal and Merger Sub
currently have no plans or proposals which relate to, or may result in, any of
the matters listed in Items 4(a)-(i) of Schedule 13D (although Vivendi
Universal reserves the right to develop such plans).

Item 5.   Interest in Securities of the Issuer.

     (a)-(b) As a result of the Tender Offer, Merger Sub has voting and
dispositive power over 27,281,606 shares of Houghton Mifflin Common Stock (the
"Subject Shares"), which represent 88.9% of the outstanding shares of Houghton
Mifflin Common Stock. Vivendi Universal also has voting power and dispositive
power over the Subject Shares. Vivendi Universal, by virtue of its ownership
of all of the capital stock of Merger Sub, is a beneficial owner of all of the
Subject Shares owned by Merger Sub. If the Merger is consummated, Merger Sub
will be merged with and into Houghton Mifflin, and Vivendi Universal will
acquire 100% of the outstanding shares of Houghton Mifflin Common Stock.

     (c) Neither Vivendi Universal nor, to the knowledge of Vivendi Universal,
any person named in Schedule A, has effected any transaction in Houghton
Mifflin Common Stock during the past 60 days. Neither Merger Sub nor, to the
knowledge of Merger Sub, any person named in Schedule B, has effected any
transaction in Houghton Mifflin Common Stock during the past 60 days.

     (d) No other person is known to have the right to receive or the power to
direct the receipt of dividends from, or the proceeds from the sale of, the
shares of Houghton Mifflin Common Stock reported in this Item 5.

     (e) Not applicable.





                                                                             7

Item. 6  Contracts, Arrangements, Understandings or Relationships with Respect
         to Securities of the Issuer.

     Other than as described in Items 3, 4 and 5 and the agreements
incorporated herein by reference and set forth in exhibits hereto, to the
knowledge of Vivendi Universal and Merger Sub, there are no contracts,
arrangements, understandings or relationships (legal or otherwise) among the
persons named in Item 2 and between such persons and any person with respect
to any securities of Houghton Mifflin, including but not limited to transfer
or voting of any of the securities, finder's fees, joint ventures, loan or
option arrangements, puts or calls, guarantees of profits, division of profits
or loss, or the giving or withholding of proxies.
