Dear Mrs. Bunzl and Gentlemen:

        This letter constitutes the agreement between American Filtrona
Corporation, a Virginia corporation (the "Company"), and each of the undersigned
(the "Shareholders") regarding shares of common stock, par value $1.00, of the
Company (the "Shares") beneficially owned by the Shareholders. The Company is
contemplating entering into a letter of intent (the "Letter of Intent") in the
form attached hereto as Exhibit A, pursuant to which the Company would be merged
or otherwise combined with an affiliate ("Newco") of Bunzl plc, an English
public limited company ("Bunzl"), on the terms described in the Letter of
Intent.

        In consideration of the Company's expenditure of efforts and incurrence
of expenses, the parties agree as follows:

        1. Each of the Shareholders hereby agrees that if:

           (a) an acquisition transaction incorporating the terms of paragraphs
           1, 2, 3 and 8(e)(f) and (h) of the Letter of Intent and providing for
           the actions described on Exhibit B attached hereto (subject to the
           limitations and exceptions set forth therein) (the "Transaction") is
           approved by the Board of Directors of the Company upon recommendation
           of the Special Committee of the Board of Directors; and

           (b) the Company has received an opinion of Goldman Sachs & Co. that
           the consideration to be received by the Company's shareholders in the
           Transaction other than a Shareholder who participates in the actions
           described in Exhibit B is fair to such shareholders, then

           (i) each of the Shareholders shall have granted a proxy as provided
               in paragraph 8(h) of the Letter of Intent, or, if he or she has
               not done so with the approval of Bunzl, then such Shareholder
               shall vote all Shares as to which he or she has voting power in
               favor of the Transaction if the Transaction involves the vote of
               the Company's shareholders; and

          (ii) each of the Shareholders shall tender or submit for exchange all
               Shares as to which he or she has dispositive power if the
               Transaction involves a tender or exchange offer.

        2.  Until the consummation of the Transaction, each of the Shareholders
hereby agrees that:

           (a) if the voting or dispositive power with respect to any Shares is
           subsequently acquired by a Shareholder, such Shares will become
           subject to the terms of this Agreement; and

           (b) without the prior approval of Bunzl, he or she will not sell,
           assign, pledge or otherwise transfer any of his or her Shares or any
           interest therein to any person except to the extent necessary to
           effect the transaction described in Exhibit B attached hereto;
           provided that Shares that are transferred either with such approval
           by Bunzl or as described on such Exhibit B shall remain subject to
           the terms of this Agreement.

        3. If (i) the Company and Newco have not entered into a definitive
agreement with respect to the Transaction by September 30, 1997, (ii) such
definitive agreement is terminated in accordance with its terms, or (iii) the
Company releases any of the Shareholders from his or her obligations under this
Agreement (with any transfer made in compliance with paragraph 2(b) above not
being deemed such a release), then this Agreement shall expire and all further
obligations of the parties hereto shall terminate.

        4. Each of the Shareholders represents that he or she, as to shares held
individually or as a trustee, has all requisite power or authority to enter into
this Agreement in the respective capacities in which he or she owns or controls
Shares, and the covenants of the Shareholders set forth herein are valid and
enforceable against him or her, respectively, in the respective capacities in
which he or she owns or controls Shares. The representations, agreements and
covenants of the Shareholders set forth herein are also intended for the benefit
of Newco and Bunzl, and Newco and Bunzl shall have the right to enforce such
agreements and covenants to the maximum extent permitted by law.

        5. Each of the parties hereto acknowledges and agrees that in the event
of any breach of this Agreement, each non-breaching party would be irreparably
and immediately harmed and could not be made whole by monetary damages. It is
accordingly agreed that the parties hereto (a) will waive, in any action for
specific performance, the defense of adequacy of a remedy at law and (b) shall
be entitled, in addition to any other remedy to which they may be entitled at
law or in equity, to compel specific performance of this Agreement in any action
instituted in a court of competent jurisdiction.

copies of this Agreement as marked. Please retain a copy for your records and
return all other copies to the Company in the enclosed envelope.
