     The Offer is conditioned upon, among other things, (a) there being validly
tendered and not properly withdrawn prior to the Expiration Date that number of
Shares which, together with any other Shares then owned by Wiley, Purchaser, or
any affiliate of Wiley or Purchaser, constitutes at least a majority of the
Shares entitled to vote generally in the election of directors or in a merger,
calculated on a fully diluted basis on the date of purchase and (b) any
applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended, having expired or been terminated. The Offer is also
subject to certain other conditions set forth in the Offer to Purchase. See the
Introduction and Sections 1 and 15 of the Offer to Purchase.

     The Board of Directors of the Company has (i) unanimously determined that
the Merger Agreement and the transactions contemplated thereby, including each
of the Offer, the Merger and the purchase of the Shares contemplated by the
Offer (collectively, the "Transactions"), are advisable and fair to, and in the
best interests of, the Company and the Company's stockholders, (ii) unanimously
approved of and adopted the Transactions and the Merger Agreement in accordance
with the requirements of the General Corporation Law of the State of Delaware
(the "DGCL") so that the provisions of Section 203 of the DGCL are not
applicable to the Transactions provided for, referred to or contemplated by, the
Merger Agreement, and (iii) resolved to recommend that the holders of Shares
accept the Offer, tender their Shares pursuant to the Offer, and approve and
adopt the Merger Agreement and the Merger.

     The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of August 12, 2001 (the "Merger Agreement"), among Wiley, the Purchaser and
the Company. The Merger Agreement provides that, among other things, the
Purchaser will make the Offer and that following the purchase of Shares pursuant
to the Offer, upon the terms and subject to the conditions set forth in the
Merger Agreement, and in accordance with the Delaware General Corporation Law
(the "DGCL"), the Purchaser will be merged with and into the Company (the
"Merger"). Following consummation of the Merger, the Company will continue as
the surviving corporation and become a direct or indirect wholly owned
subsidiary of Wiley. At the effective time of the Merger, each outstanding Share
(other than Shares held by (a) the Company or any of its subsidiaries, (b)
Wiley, Purchaser or any of Wiley's direct or indirect wholly owned subsidiaries,
or (c) stockholders, if any, who are entitled to and properly exercise appraisal
rights under the DGCL), will be converted into the right to receive the price
per Share paid pursuant to the Offer in cash, without interest, as set forth in
the Merger Agreement and


                                       2



described in the Offer to Purchase.

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), the Purchaser will accept for payment and pay for Shares which
are validly tendered prior to the Expiration Date and not theretofore properly
withdrawn when, as and if Purchaser gives oral or written notice to the
Depositary of the Purchaser's acceptance of such Shares for payment pursuant to
the Offer. Payment for Shares purchased pursuant to the Offer will in all cases
be made only after timely receipt by the Depositary of (a) certificates for such
Shares, or timely confirmation of a book-entry transfer of such Shares into the
Depositary's account at The Depository Trust Company, pursuant to the procedures
described in Section 3 of the Offer to Purchase, (b) a properly completed and
duly executed Letter of Transmittal or an Agent's Message (as defined in the
Offer to Purchase) in connection with a book-entry transfer and (c) all other
documents required by the Letter of Transmittal.

     In order to take advantage of the Offer, a duly executed and properly
completed Letter of Transmittal, with any required signature guarantees, or an
Agent's Message in connection with a book-entry transfer of Shares, and any
other required documents, should be sent to the Depositary, and certificates
representing the tendered Shares should be delivered or such Shares should be
tendered by book-entry transfer and a Book-Entry Confirmation (as defined in the
Offer to Purchase), to the Depositary, all in accordance with the instructions
set forth in the Letter of Transmittal and in the Offer to Purchase.

     If holders of Shares wish to tender, but it is impracticable for them to
forward their certificates or other required documents or to complete the
procedures for delivery by book-entry transfer prior to the Expiration Date,
such holders must tender their Shares in accordance with the guaranteed delivery
procedures specified in Section 3 of the Offer to Purchase.

     Neither Purchaser nor Wiley will pay any fees or commissions to any broker
or dealer or other person (other than the Depositary and us, as described in the
Offer to Purchase) for soliciting tenders of Shares pursuant to the Offer.
Purchaser will, however, upon request, reimburse brokers, dealers, commercial
banks and trust companies for customary mailing and handling costs incurred by
them in forwarding the enclosed materials to their customers.

     Purchaser will pay or cause to be paid all stock transfer taxes applicable
to its purchase of Shares pursuant to the Offer, subject to Instruction 6 of the
Letter of Transmittal.

     Any inquiries you may have with respect to the Offer should be addressed
to, and additional copies of the enclosed materials may be obtained from, us at
our address and telephone number set forth on the back cover of the Offer to
Purchase.

                                                        Very truly yours,


                                                        D.F. King & Co., Inc.
