            The consideration to be used to purchase 120,987 of the shares of

defined below).

            As more fully described in Item 4 hereof, the funds used by Abra

                                 Page 17 of 20


<PAGE>

            On December 28, 2000, Abra LLC entered into a Voting Agreement
with the Company (the "Abra Voting Agreement") pursuant to which, among other
things, Abra LLC (i) agreed to vote (or cause to be voted) all of the shares
of Company Common Stock beneficially owned by Abra LLC on the record date of
such vote or action (a) in favor of the Merger, the execution and delivery of
the Merger Agreement and the approval of the terms thereof and each of the
other transactions contemplated by the Merger Agreement; and (b) against any
amendment of the Company's certificate of incorporation or bylaws
which amendment would prevent or materially impede, interfere with or delay
the Merger, the Merger Agreement or any of the other transactions
contemplated by the Merger Agreement and (ii) appointed the Chairman and
Chief Executive Officer of the Company and the President, Corporate
Development of About, or any other designee of the Company, each of them
individually, as Abra LLC's proxy and attorney-in-fact (with full power of
substitution) to vote or act by written consent with respect to Abra LLC's
shares of Company Common Stock.  The Abra Voting Agreement terminates on the
earlier of (i) the effective time of the Merger and (ii) the termination of
the Merger Agreement pursuant to its terms.

            On December 28, 2000, Abra LLC beneficially owned 2,236,641
shares of Company Common Stock, which amounted to 10.46% of the total
outstanding shares of Company Common Stock.

            On December 29, 2000, the Company entered into a definitive
agreement (the "List Rental Agreement") with PRIMEDIA Magazines, pursuant to
which the Company will issue 120,987 shares of Company Common Stock to
PRIMEDIA Magazines in consideration of the provision by PRIMEDIA Magazines of
the right to use a mailing list owned by PRIMEDIA Magazines. The shares of
Company Common Stock to be issued to PRIMEDIA Magazines pursuant to the List
Rental Agreement were valued at $2,450,000 based on a $20.25 pro forma
equivalent per share value of Company Common Stock. Pursuant to the List
Rental Agreement, 120,987 shares of Company Common Stock will be issued to
PRIMEDIA Magazines promptly.

            The foregoing summaries of the Abra Voting Agreement and the
List Rental Agreement do not purport to be complete and are subject to, and
qualified in their entirety by reference to, the provisons of the agreements
filed as exhibits hereto. A copy of (a) the Abra Voting Agreement is attached
hereto as Exhibit 10, and (b) the List Rental Agreement is attached hereto as
Exhibit 11.

            From January 2, 2001 to January 3, 2001, Abra LLC and PRIMEDIA
purchased an aggregate of 199,000 shares of Company Common Stock for an
aggregate purchase price of $5,291,556.90 in cash. Of those shares, Abra LLC
bought 176,891 and PRIMEDIA bought 22,109.

            The Reporting Persons may, from time to time, acquire additional
Company Common Stock in the open market or through privately negotiated
transactions.

            Except as set forth above, the Reporting Persons have no present
plans or proposals which relate to or would result in any actions described in
subparagraphs (a) through (j) of Item 4 of Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

            (a) The responses of the Reporting Persons to Rows (7) through (13)
of the cover page of this statement on Schedule 13D are incorporated herein by
reference.

            Except as disclosed in this Item 5(a), none of the Reporting
Persons, nor, to the best knowledge of the Reporting Persons, any of the other
persons named in Item 2 or on Schedule A hereto, beneficially owns any shares of
Company Common Stock.

            (b) The responses of the Reporting Persons to (i) Rows (7) through
(13) of the cover page of this statement on Schedule 13D and (ii) Item 5(a)
hereof are incorporated herein by reference.

            As further described in Item 4, PRIMEDIA and Abra LLC purchased
an aggregate of 199,000 shares of Company Common Stock in the open market for
an aggregate purchase price of $5,291,556.90. These acquisitions of Company
Common Stock as described in Item 4 may mean that Abra LLC, PRIMEDIA and the
other Reporting Persons are a "group" for purposes of Rule 13d-1 of the
Securities Exchange Act of 1934, as amended. In addition, because of
PRIMEDIA Magazine's right to acquire 120,987 shares of Company Common Stock
pursuant to the List Rental Agreement, PRIMEDIA may be deemed to be the
"beneficial owner" of those shares.

            Except as disclosed in this Item 5(b), none of the Reporting
Persons, nor, to the best knowledge of the Reporting Persons, any of the other
persons named in Item 2 or on Schedule A hereto, presently has the power to vote
or to direct the vote or to dispose or direct the disposition of any of shares
of Company Common Stock or other securities of the Company which they may be
deemed to beneficially own.

            (c) Except as disclosed in Item 4 hereof, none of the Reporting
Persons, nor, to the best knowledge of the Reporting Persons, any of the other
persons named in Item 2 or on Schedule A hereto, has effected any transaction in
the Company Common Stock during the past 60 days.

            (d)  Not applicable.

            (e)  Not applicable.

            Neither the filing of this Schedule 13D or any amendment thereto,
nor anything contained herein is intended as, or should be construed as, an
admission that the Reporting Persons are the "beneficial owner" of any shares of
Company Common Stock or other securities of the Company.

     WHEREAS, each Shareholder beneficially owns the number of shares of common

any other shares of capital stock of the Company such Shareholder acquires after

     NOW, THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the parties hereby agree as follows

     Section 1. REPRESENTATIONS AND WARRANTIES OF THE SHAREHOLDERS. Each
Shareholder severally represents and warrants to the Company as follows:

     (a) The execution, delivery and performance of this Agreement and the

authorized by such Shareholder, and no other proceedings on the part of such
Shareholder are necessary to authorize this Agreement or to consummate the

     (c) The execution, delivery and performance by such Shareholder of this
Agreement and the consummation of the transactions contemplated hereby do not
and will not (i) contravene or conflict with its organizational documents; (ii)

occurrences that would not reasonably be expected to prevent, delay or impair
such Shareholder's ability to consummate the transactions contemplated by this
Agreement.

     (d) Other than any filings required by the Exchange Act or the rules and
regulations promulgated thereunder, the execution, delivery and performance by
such Shareholder of this Agreement and the consummation of the transactions
contemplated hereby by such Shareholder require no filings, notices,
declarations, consents or other actions to be made by such Shareholder with, nor

such Shareholder from, any governmental authority.

     (e) As of the date hereof, there is no action, suit, claim, investigation
or proceeding pending or, to the knowledge of such Shareholder, threatened
against such Shareholder or its properties before any court or arbitrator or any
governmental authority which challenges or seeks to prevent, enjoin, alter or
delay the Merger or any of the other transactions contemplated hereby or by the
Merger Agreement. As of the date hereof, such Shareholder is not, and none of
its properties is, subject to any order, writ, judgment, injunction, decree,
determination or award which would prevent, delay or impair the consummation of
the transactions contemplated hereby.

arrangements to which such Shareholder is a party relating to the Shares held by
such Shareholder, other than this Agreement.

owned (within the meaning of Rule 13d-3 under the Exchange Act) by such
Shareholder.

the Merger, the Merger Agreement or the other transactions contemplated by the
Merger Agreement is sought, such Shareholder shall vote (or cause to be voted)

thereof or in any other circumstances upon which their vote, consent or other
approval is sought, such Shareholder shall vote (or cause to be voted) the
Shares held by such Shareholder against (A) any Acquisition Proposal or (B) any
amendment of the Company's Certificate of Incorporation or By-laws which
amendment would in any manner prevent or materially impede, interfere with or
delay the Merger, the Merger Agreement or any of the other transactions
contemplated by the Merger Agreement; and

     (c) Such Shareholder shall grant to, and appoint, Scott P. Kurnit and Alan
P. Blaustein or any other individual who is designated by the Company, until the

            Mailing List to About no later than December 29, 2000. Upon such
            delivery, About shall immediately acknowledge receipt and acceptance
            of the Mailing List in writing. About agrees and acknowledges that
            upon such delivery, PRIMEDIA's obligations relating to the Mailing
            List are fully satisfied.

      2.    In consideration of the use of the Mailing List, About shall issue
            to PRIMEDIA 120,987 shares of common stock of About, par value $.001
            per share on the date hereof with an aggregate value equal to
            $2,450,000 (the "Common Stock"). The Common Stock shall be issued to
            PRIMEDIA promptly upon of the execution of this Agreement. The

            registration on Form S-8 or registrations for issuing stock in the
            context of an acquisition.

      3.    About hereby unconditionally promises, agrees, represents and
            warrants that as a condition to the use of the Mailing List it will

            permit any third party, agent, employee or contractor of their
            respective agents or employees to do any of the foregoing,
            regardless of whether the Mailing List takes the form of printed
            labels, magnetic tape or otherwise; (ii) disclose the identity of
            PRIMEDIA as the list owner or the derivation or source of the
            Mailing List to any third party; (iii) use the Mailing List as a
            basis for a phone or e-mail solicitation; (iv) use the Mailing List
            in connection with "free offers" or for any other offer in which a
            negative response is requested or solicited. About shall erase the
            Mailing List from all storage devices upon which it is stored
            immediately upon processing its mailing.

      4.    About acknowledges that the Mailing List is the property of
            PRIMEDIA.

      5.    About acknowledges that the Mailing List has and will continue to be

            one or more methods of computer control and or planted and/or varied
            names and addresses. About hereby consents to such controls.

            (i) the accuracy of the Mailing List's names and addresses; (ii) the
            results to be obtained from the use of the Mailing List or (iii) the

            all claims, damages, liabilities, expenses, including but not
            limited to attorney fees and expenses, however incurred, relating to

            hereto. Any party may waive compliance by another with any of the
            provisions of this Agreement. No waiver of any provision hereof

            thereafter to enforce each and every such provision.

      10.   If any provision of this Agreement is held by any court of competent
            jurisdiction to be illegal, invalid or unenforceable, such provision
            shall be of no force and effect, but the illegality, invalidity or
            unenforceability shall have no effect upon and shall not impair the
            enforceability of any other provision of this Agreement.

      11.   None of the parties hereto may assign any of its rights or delegate
            any of its duties under this Agreement without the prior written
            consent of the others. All of the terms and provisions of this
            Agreement shall be binding on, and shall inure to the benefit of,
            the respective successors and permitted assigns of the parties.

            in this Agreement are for the sole benefit of the parties hereto and
            their respective successors and permitted assigns and they shall not
            be construed as conferring and are not intended to confer any rights
            on any other persons.

      13.   This Agreement may be executed in two (2) or more counterparts, each
            of which shall be deemed an original, and each party thereto may
            become a party hereto by executing a counterpart hereof. This
            Agreement and any counterpart so executed shall be deemed to be one
            and the same instrument. The exchange (by facsimile) of facsimile
            copies of executed counterparts of this Agreement shall be deemed
            execution and delivery thereof, provided that receipt of such
            facsimile is confirmed in writing. Original copies shall follow by
            documented overnight delivery.

      14.   The parties hereto agree that in interpreting this Agreement there
