                             AMENDMENT NO. 4 TO THE
                          1999 STOCK INCENTIVE PLAN OF
                                  AMETEK, INC.

      WHEREAS, AMETEK, Inc. has adopted the 1999 Stock Incentive Plan of AMETEK,
Inc. (the "Plan"); and

      WHEREAS, Section 18 of the Plan permits the Committee, as defined in the
Plan (the "Committee") to amend the Plan; and

      WHEREAS, the Committee now desires to amend the Plan in certain respects;
NOW, THEREFORE, the Plan is hereby amended as follows:

      1.    Section 13 of the Plan is hereby amended by revising the first and
            second paragraphs of the section as follows:

            "13. Termination of Employment. If a holder of an Option and/or
            Rights shall voluntarily or involuntarily leave the employ or
            service of the Corporation and its Affiliates (including
            retirement), the Option and Rights of such holder shall terminate
            forthwith, except that the holder shall have until the expiration of
            3 months from the cessation of the holder's employment or service
            with the Corporation and its Affiliates (without regard to any
            period of severance) to exercise any unexercised Option and/or
            Rights the holder could have exercised on the day on which he left
            the employ or service of the Corporation and Affiliates, including
            those Options and/or Rights that become exercisable upon cessation
            of employment pursuant to the provisions of the first paragraph of
            Section 9 hereof.

            If the cessation of employment or service is due to death, the
            representatives of the estate of the holder shall have the privilege
            of exercising the unexercised Options and/or Rights which the
            deceased could have exercised at the time of his death, including
            those Options and/or Rights that become exercisable pursuant to the
            provisions of the first paragraph of Section 9 hereof, provided that
            such exercise must be accomplished prior to the expiration of such
            Options and/or Rights and within six months after the death of the
            holder.

            The Committee may, in its sole discretion, provide with respect to
            an Option or Rights granted to any individual (and either at the
            time of grant of such Option or Rights or by an amendment thereafter
            to any such outstanding Option or Rights), that the post-termination
            or post-death exercise period shall be for a period of time
            specified by the
<PAGE>
            Committee which is longer than the period which would otherwise
            apply pursuant to this Section 13, but in no event beyond the
            expiration of the stated term of such Option or Rights. If the
            employment or service of any holder with the Corporation or an
            Affiliate shall be terminated because of the holder's violation of
            the duties of such employment or service with the Corporation or its
            Affiliates, as he may from time to time have, the existence of which
            violation shall be determined by the Committee in its sole
            discretion and which determination by the Committee shall be
            conclusive, all unexercised Options and Rights of such holder shall
            terminate immediately upon the termination of the holder's
            employment or service with the Corporation or an Affiliate, and a
            holder whose employment or service with the Corporation or an
            Affiliate is so terminated shall have no right after such
            termination to exercise any unexercised Option or Rights he might
            have exercised prior to the termination of his employment or service
            with the Corporation or an Affiliate. "

      2.    The provisions of this Amendment No. 4 shall be effective as of
            September 25, 2002.

      3.    Except to the extent hereinabove set forth, the Plan shall remain in
            full force and effect.

      IN WITNESS WHEREOF, the Committee has caused this Amendment No. 4 to be
executed by a duly authorized officer of the Company, and its corporate seal to
be affixed, as of the 25th day of September, 2002.

                                           AMETEK, Inc.

Kathryn E. Londra (SEAL)AMENDMENT TO RIGHTS AGREEMENT

       This Amendment to Rights Agreement, effective as of the 30th day of
September, 2002, is made and entered into by and among U.S. Bank National
Association ("U.S. Bank"), Banta Corporation, a Wisconsin corporation (the
"Company"), and American Stock Transfer & Trust Company, a New York banking
corporation ("AST").

                                   WITNESSETH

       WHEREAS, the Company and U.S. Bank (as successor to Firstar Bank, N.A.)
are parties to that certain Rights Agreement, dated as of November 5, 2001, a
copy of which is attached hereto as Exhibit A (the "Rights Agreement"), pursuant
to which U.S. Bank undertook the duties and obligations of the Rights Agent (as
defined in the Rights Agreement) under the terms and conditions of the Rights
Agreement;

       WHEREAS, U.S. Bank has notified the Company that it will resign as such
Rights Agent;

       WHEREAS, pursuant to Section 21 of the Rights Agreement, the Company
agrees to discharge U.S. Bank from its duties as Rights Agent under the Rights
Agreement;

       WHEREAS, the Company desires to appoint AST as a successor Rights Agent
under the Rights Agreement, and AST desires to undertake and perform the duties
and obligations of the Rights Agent under the terms and conditions of the Rights
Agreement;

       WHEREAS, the Company has directed U.S. Bank to amend Section 21 of the
Rights Agreement as necessary to allow the Company to appoint AST as a successor
Rights Agent under the Rights Agreement.

       NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, and intending to be legally bound
hereby, the parties agree as follows:

       1. Amendment of Section 21 of Rights Agreement. Section 21 of the Rights
Agreement is hereby amended and restated in its entirety to read as follows:

              "Section 21. Change of Rights Agent. The Rights Agent or any
       successor Rights Agent may resign and be discharged from its duties under
       this Agreement upon 30 days' notice in writing mailed to the Company and
       to each transfer agent of the Common Shares by registered or certified
       mail and, if separate Right Certificates have been issued as of the date
       of such notice as contemplated by Section 3 hereof, to the holders of the
       Right Certificates by first-class mail. The Company may remove the Rights
       Agent or any successor Rights Agent upon 30 days' notice in writing,
       mailed to the Rights Agent or successor Rights Agent, as the case may be,
       and to each transfer agent of the Common Shares by registered or
       certified mail, and, if separate Right

<PAGE>

       Certificates have been issued as of the date of such notice as
       contemplated by Section 3 hereof, to the holders of the Right
       Certificates by first-class mail. If the Rights Agent shall resign or be
       removed or shall otherwise become incapable of acting, the Company shall
       appoint a successor to the Rights Agent. If the Company shall fail to
       make such appointment within a period of 30 days after giving notice of
       such removal or after it has been notified in writing of such resignation
       or incapacity by the resigning or incapacitated Rights Agent or by the
       holder of a Right Certificate (who shall, with such notice, submit his
       Right Certificate for inspection by the Company), then the registered
       holder of any Right Certificate may apply to any court of competent
       jurisdiction for the appointment of a new Rights Agent. Any successor
       Rights Agent, whether appointed by the Company or by such a court, shall
       be (a) a corporation organized and doing business under the laws of the
       United States or of the State of New York or the State of Wisconsin (or
       of any other state of the United States so long as such corporation is
       authorized to do business in the State of New York or the State of
       Wisconsin), in good standing, having an office or agency in the State of
       Wisconsin or the State of New York, which is authorized under such laws
       to exercise corporate trust or stock transfer powers and is subject to
       supervision or examination by federal or state authority and which has at
       the time of its appointment as Rights Agent a combined capital and
       surplus of at least $10 million, or (b) an Affiliate of a corporation
       described in clause (a) of this sentence. After appointment, the
       successor Rights Agent shall be vested with the same powers, rights,
       duties and responsibilities as if it had been originally named as Rights
       Agent without further act or deed; but the predecessor Rights Agent shall
       deliver and transfer to the successor Rights Agent any property at the
       time held by it hereunder, and execute and deliver any further assurance,
       conveyance, act or deed necessary for the purpose. Not later than the
       effective date of any such appointment the Company shall file notice
       thereof in writing with the predecessor Rights Agent and each transfer
       agent of the Common Shares, and, if separate Right Certificates have been
       issued as of such effective date as contemplated by Section 3 hereof,
       mail a notice thereof in writing to the registered holders of the Right
       Certificates. Failure to give any notice provided for in this Section 21,
       however, or any defect therein, shall not affect the legality or validity
       of the resignation or removal of the Rights Agent or the appointment of
       the successor Rights Agent, as the case may be."

       2. Appointment. The Company hereby appoints AST as a successor Rights
Agent under the terms and conditions of the Rights Agreement, as amended
pursuant to Section 1 above (as so amended, the "Amended Rights Agreement").

       3. Assumption. AST hereby accepts the appointment as agent for the
Company and the holders of Rights under the Amended Rights Agreement, and AST
hereby assumes and agrees to perform all of the duties and obligations of the
Rights Agent under the terms and conditions of the Amended Rights Agreement.

                                      -2-
<PAGE>

       4. Notice. U.S. Bank hereby acknowledges that this instrument constitutes
notice to U.S. Bank, as the Company's transfer agent, pursuant to Section 21 of
the Amended Rights Agreement that the Company has appointed AST as the successor
Rights Agent to U.S. Bank under the Amended Rights Agreement and that U.S. Bank
is hereby discharged as such Rights Agent.

       5. No Further Amendment. Except as provided in Section 1 above, the terms
and conditions of the Amended Rights Agreement shall be unaffected by this
instrument and shall remain in full force and effect. The Company and AST each
acknowledge that pursuant to Section 28 of the Amended Rights Agreement the
respective covenants and provisions of the Amended Rights Agreement by or for
the benefit of the Company or the Rights Agent shall bind and inure to the
benefit of their respective successors and assigns thereunder.

       6. Governing Law. This instrument shall be deemed to be a contract made
under the laws of the State of Wisconsin and for all purposes shall be governed
by and construed in accordance with the laws of such State applicable to
contracts to be made and performed entirely within such State.

       7. Counterparts. This instrument may be executed in any number of
counterparts, and each of such counterparts shall for all purposes be deemed to
be an original, and all such counterparts shall together constitute but one and
the same instrument.

       IN WITNESS WHEREOF, the parties hereto have executed this instrument,
effective as of the date recited above.
