                          CERTIFICATE OF DETERMINATION

                                       of

                      JUNIOR PARTICIPATING PREFERRED STOCK

                                       of

                                  FURON COMPANY



               The undersigned officers of Furon Company, a California
corporation (the "Corporation"), hereby certify that the following resolution
has been duly adopted by the Board of Directors of the Corporation:

               RESOLVED, that pursuant to the authority granted to the Board of
Directors of the Corporation by the Articles of Incorporation, a series of
shares of the Preferred Stock of the Corporation is hereby established and the
number of shares constituting such series and the designation thereof, and the
rights, preferences, privileges and restrictions of the shares of such series,
are fixed and established as follows:

                            I. Designation and Amount

               The shares of such series shall be designated as "Junior
Participating Preferred Stock" (the "Junior Preferred Stock") and the number of
shares constituting the Junior Preferred Stock shall be 300,000. Such number of
shares may be increased or decreased by resolution of the Board of Directors;
provided, that no decrease shall reduce the number of shares of Junior Preferred
Stock to a number less than the number of shares then outstanding plus the
number of shares reserved for issuance upon the exercise of outstanding options,
rights or warrants or upon the conversion of any outstanding securities issued
by the Corporation convertible into Junior Preferred Stock.

                         II. Dividends and Distributions

        (A) Subject to the rights of the holders of any shares of any series of
        Preferred Stock (or any similar stock) ranking prior and superior to the
        Junior Preferred Stock with respect to dividends, the holders of shares
        of Junior Preferred Stock, in preference to the holders of Common Stock
        of the Corporation, shall be entitled to receive, when, as and if
        declared by the Board of Directors out of funds legally available for
        the purpose, quarterly dividends payable in cash on the first day of
        March, June, September and December in each year (each such date being
        referred to herein as a "Quarterly Dividend Payment Date"), commencing
        on the first Quarterly Dividend Payment Date after the first issuance of
        a share or fraction of a share of Junior Preferred Stock, in an amount
        per share (rounded to

   2


        the nearest cent) equal to the greater of (a) $1.00 or (b) subject to
        the provision for adjustment hereinafter set forth, 100 times the
        aggregate per share amount of all cash dividends, and 100 times the
        aggregate per share amount (payable in kind) of all non-cash dividends
        or other distributions, other than a dividend payable in shares of
        Common Stock or a subdivision of the outstanding shares of Common Stock
        (by reclassification or otherwise), declared on the Common Stock since
        the immediately preceding Quarterly Dividend Payment Date or, with
        respect to the first Quarterly Dividend Payment Date, since the first
        issuance of any share or fraction of a share of Junior Preferred Stock.
        In the event the Corporation shall at any time declare or pay any
        dividend on the Common Stock payable in shares of Common Stock, or
        effect a subdivision or combination or consolidation of the outstanding
        shares of Common Stock (by reclassification or otherwise than by payment
        of a dividend in shares of Common Stock) into a greater or lesser number
        of shares of Common Stock, then in each such case the amount to which
        holders of shares of Junior Preferred Stock were entitled immediately
        prior to such event under clause (b) of the preceding sentence shall be
        adjusted by multiplying such amount by a fraction, the numerator of
        which is the number of shares of Common Stock outstanding immediately
        after such event and the denominator of which is the number of shares of
        Common Stock that were outstanding immediately prior to such event.

        (B) The Corporation shall declare a dividend or distribution on the
        Junior Preferred Stock as provided in paragraph (A) of this Section
        immediately after it declares a dividend or distribution on the Common
        Stock (other than a dividend payable in shares of Common Stock);
        provided that, in the event no dividend or distribution shall have been
        declared on the Common Stock during the period between any Quarterly
        Dividend Payment Date and the next subsequent Quarterly Dividend Payment
        Date, a dividend of $1.00 per share on the Junior Preferred Stock shall
        nevertheless be payable on such subsequent Quarterly Dividend Payment
        Date.

        (C) Dividends shall begin to accrue and be cumulative on outstanding
        shares of Junior Preferred Stock from the Quarterly Dividend Payment
        Date next preceding the date of issue of such shares, unless the date of
        issue of such shares is prior to the record date for the first Quarterly
        Dividend Payment Date, in which case dividends on such shares shall
        begin to accrue from the date of issue of such shares, or unless the
        date of issue is a Quarterly Dividend Payment Date or is a date after
        the record date for the determination of holders of shares of Junior
        Preferred Stock entitled to receive a quarterly dividend and before such
        Quarterly Dividend Payment Date, in either of which events such
        dividends shall begin to accrue and be cumulative from such Quarterly
        Dividend Payment Date. Accrued but unpaid dividends shall not bear
        interest. Dividends paid on the shares of Junior Preferred Stock in an
        amount less than the total amount of such dividends at the time accrued
        and payable on such shares shall be allocated pro rata on a
        share-by-share basis among all such shares at the time outstanding. The
        Board of Directors may fix a record date for the determination of
        holders of shares of Junior Preferred Stock entitled to receive payment
        of a dividend or distribution


                                       2

   3

        declared thereon, which record date shall be not more than 60 days
        prior to the date fixed for the payment thereof.

                               III. Voting Rights

               The holders of shares of Junior Preferred Stock shall have the
following voting rights:

        (A) Subject to the provision for adjustment hereinafter set forth, each
        share of Junior Preferred Stock shall entitle the holder thereof to 100
        votes on all matters submitted to a vote of the shareholders of the
        Corporation.

        (B) Except as otherwise provided herein, or in any other resolutions of
        the Board creating a series of Preferred Stock or any similar stock, or
        by law, the holders of shares of Junior Preferred Stock and the holders
        of shares of Common Stock and any other capital stock of the Corporation
        having general voting rights shall vote together as one class on all
        matters submitted to a vote of shareholders of the Corporation.

        (C) Except as set forth herein, in the Corporation's Articles of
        Incorporation or as otherwise provided by law, holders of Junior
        Preferred Stock shall have no voting rights.

                            IV. Certain Restrictions

        (A) Whenever quarterly dividends or other dividends or distributions
        payable on the Junior Preferred Stock as provided in Section II are in
        arrears, thereafter and until all accrued and unpaid dividends and
        distributions, whether or not declared, on shares of Junior Preferred
        Stock outstanding shall have been paid in full, the Corporation shall
        not:

               (i) declare or pay dividends, or make any other distributions, on
               any shares of stock ranking junior (either as to dividends or
               upon liquidation, dissolution or winding up) to the Junior
               Preferred Stock;

               (ii) declare or pay dividends, or make any other distributions,
               on any shares of stock ranking on a parity (either as to
               dividends or upon liquidation, dissolution or winding up) with
               the Junior Preferred Stock, except dividends paid ratably on the
               Junior Preferred Stock and all such parity stock on which
               dividends are payable or in arrears in proportion to the total
               amounts to which the holders of all such shares are then
               entitled;

               (iii) redeem or purchase or otherwise acquire for consideration
               shares of any stock ranking junior (either as to dividends or
               upon liquidation, dissolution or winding up) to the Junior
               Preferred Stock, provided that the Corporation may at any time
               redeem, purchase or otherwise acquire shares of any such junior
               stock in exchange for shares of any stock of the


                                       3

   4


               Corporation ranking junior (either as to dividends or upon
               dissolution, liquidation or winding up) to the Junior Preferred
               Stock; or

               (iv) redeem or purchase or otherwise acquire for consideration
               any shares of Junior Preferred Stock, or any shares of stock
               ranking on a parity with the Junior Preferred Stock, except in
               accordance with a purchase offer made in writing or by
               publication (as determined by the Board of Directors) to all
               holders of such shares upon such terms as the Board of Directors,
               after consideration of the respective annual dividend rates and
               other relative rights and preferences of the respective series
               and classes, shall determine in good faith will result in fair
               and equitable treatment among the respective series or classes.

        (B) The Corporation shall not permit any subsidiary of the Corporation
        to purchase or otherwise acquire for consideration any shares of stock
        of the Corporation unless the Corporation could, under paragraph (A) of
        this Section IV purchase or otherwise acquire such shares at such time
        and in such manner.

                              V. Reacquired Shares

               Any shares of Junior Preferred Stock purchased or otherwise
acquired by the Corporation in any manner whatsoever shall be retired and
cancelled promptly after the acquisition thereof. All such shares shall upon
their cancellation become authorized but unissued shares of Preferred Stock and
may be reissued as part of a new series of Preferred Stock subject to the
conditions and restrictions on issuance set forth herein, in the Articles of
Incorporation, in any other Certificate of Determination creating a series of
Preferred Stock or any similar stock or as otherwise required by law.

                   VI. Liquidation, Dissolution or Winding Up

Upon any liquidation, dissolution or winding up of the Corporation, no
distribution shall be made (1) to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to the
Junior Preferred Stock unless, prior thereto, the holders of shares of Junior
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Junior
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount to be distributed per share to holders of shares of
Common Stock, or (2) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Junior Preferred Stock, except distributions made ratably on the Junior
Preferred Stock and all such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up. In the event the Corporation shall at any time
declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in


                                       4

   5

shares of Common Stock) into a greater or lesser number of shares of Common
Stock, then in each such case the aggregate amount to which holders of shares of
Junior Preferred Stock were entitled immediately prior to such event under the
proviso in clause (1) of the preceding sentence shall be adjusted by multiplying
such amount by a fraction the numerator of which is the number of shares of
Common Stock outstanding immediately after such event and the denominator of
which is the number of shares of Common Stock that were outstanding immediately
prior to such event.

                        VII. Consolidation, Merger, etc.

               In case the Corporation shall enter into any consolidation,
merger, combination or other transaction in which the shares of Common Stock are
exchanged for or changed into other stock or securities, cash and/or any other
property, then in any such case each share of Junior Preferred Stock shall at
the same time be similarly exchanged or changed into an amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount of stock, securities, cash and/or any other property
(payable in kind), as the case may be, into which or for which each share of
Common Stock is changed or exchanged. In the event the Corporation shall at any
time declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the amount set forth in the
preceding sentence with respect to the exchange or change of shares of Junior
Preferred Stock shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

                                VIII. Redemption

               The shares of Junior Preferred Stock shall not be redeemable.

                                    IX. Rank

               The Junior Preferred Stock shall rank, with respect to the
payment of dividends and the distribution of assets, junior to all series of any
other class of the Corporation's Preferred Stock.

                                  X. Amendment

               The Articles of Incorporation of the Corporation shall not be
amended in any manner which would alter or change the powers, preferences or
special rights of the Junior Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of at least two-thirds of the
outstanding shares of Junior Preferred Stock, voting together as a single class.

     *                    *                     *                    *
