                  This Amendment No. 2 (this "Amendment") amends and supplements
the Tender Offer Statement on Schedule TO filed with the Securities and Exchange
Commission on March 22, 2000 (the "Schedule TO"), by WTI Acquisition
Corporation, a Delaware corporation ("Purchaser") and an indirect wholly owned
subsidiary of The Thomson Corporation, a corporation organized under the laws of
Ontario, Canada ("Thomson"). The Schedule TO relates to the offer by Purchaser
to purchase all outstanding shares of Common Stock, par value $0.50 per share
(the "Shares"), of Wave Technologies International, Inc., a Missouri corporation
(the "Company"), at a purchase price of $9.75 per Share, net to the seller in
cash, upon the terms and subject to the conditions set forth in the Offer to
Purchase dated March 22, 2000 (the "Offer to Purchase") and in the related
Letter of Transmittal, copies of which are filed as Exhibits (a)(1) and (a)(2),
respectively, to the Schedule TO. Capitalized terms used and not defined herein
shall have the meanings ascribed to such terms in the Offer to Purchase or in
the Schedule TO.

Item 5.           Past contacts, Transactions, Negotiations and Agreements.

                  Item 5 of the Schedule TO is hereby amended by amending and
restating in its entirety the fourth paragraph under Section 10 "Background of
the Offer; Contacts with the Company; the Merger Agreement; Interests of Certain
Persons in the Merger. Background of the Merger and the Offer" on page 15 of the
Offer to Purchase as follows:

                  Between February 4 and February 14, 2000, Messrs. Shuman and
McEwen discussed a possible range of values for Wave with Raymond J. Kalinowsky,
a member of the Wave Board of Directors and representatives of U.S. Bancorp
Piper Jaffray. In a telephone conversation on February 14, 2000 among Mr.
Kalinowsky, Mr. Shuman and a representative of U.S. Bancorp Piper Jaffray, the
parties continued to discuss the terms of a potential acquisition transaction.
The parties discussed how to structure the proposed transaction and agreed to
use an all-cash tender offer, in order to deliver value to the holders of Shares
quickly. The purchase price proposed by Thomson in early February was in the
amount of $9.00 per share, which was raised through further negotiations to the
offer price of $9.75 per share.

Item 11.          Additional Information

                  (a) Item 11 of the Schedule TO is hereby amended by amending
and restating in its entirety the third paragraph under Section 7 "Certain
Information Concerning the Company" on page 10 of the Offer to Purchase as
follows:

                  Certain Projected Financial Data of the Company. Prior to
entering into the Merger Agreement, Thomson conducted a due diligence review of
the Company and in connection with such review received certain projections of
the Company's future operating performance. The projections are included by
Purchaser and Thomson in this Offer to Purchase solely because such information
was furnished to Thomson and Purchaser by the Company. The Company does not in
the ordinary course publicly disclose projections and these projections were not
prepared with a view to public disclosure. The Company has advised Thomson and
Purchaser that these projections were prepared by the Company's management based
on numerous assumptions including, among others, projections of revenues,
operating income, benefits and other expenses, depreciation and amortization,
capital expenditure and working capital requirements. No assurances can be given
with respect to any such assumptions. These projections do not give effect to
the Offer or the potential combined



operations of Thomson and the Company or any alterations Thomson may make to the
Company's operations or strategy after the consummation of the Offer. The
information set forth below is presented for the limited purpose of giving the
stockholders access to the material financial projections prepared by the
Company's management that were made available to Thomson and Purchaser in
connection with the Merger Agreement and the Offer.

                  (b) Item 11 of the Schedule TO is hereby amended by amending
and restating in its entirety the fifth paragraph under Section 7 "Certain
Information Concerning the Company" on page 11 of the Offer to Purchase as
follows:

                  In addition, these projections were not prepared in accordance
with generally accepted accounting principles, and neither the Company's nor
Thomson's independent accountants has examined or compiled any of these
projections or expressed any conclusion or provided any other form of assurance
with respect to these projections and accordingly assume no responsibility for
these projections. These projections were prepared with a limited degree of
precision, and were not prepared with a view to public disclosure or compliance
with the published guidelines of the Commission or the guidelines established by
the American Institute of Certified Public Accountants regarding projections,
which would require a more complete presentation of data than as shown above.
The inclusion of these projections herein should not be regarded as a
representation by Thomson, Purchaser or the Company that the projected results
will be achieved. These projections should be read in conjunction with the
historical financial information of the Company. Neither Thomson or Purchaser
assumes any responsibility for the accuracy or validity of the foregoing
projections. Forward-looking statements also include those preceded by, followed
by or that include the words "believes", "expects", "anticipates" or similar
expressions.
