         1.       The corporation shall indemnify any person who was or is a 
         party or is threatened to be made a party to any threatened, pending,
         or completed action or suit by or in the right of the corporation to
         procure a judgment in its favor by reason of the fact that such person
         is or was a corporate director, officer, employee, or agent, or is or
         was serving at the corporation's request as a director, officer,
         employee, or agent of another corporation, partnership, joint venture,
         trust, or other enterprise against expenses, including attorney's fees,
         actually and reasonably incurred by that person in connection with the
         defense or settlement of the action or suit, if such person has acted
         in good faith and in a manner that person reasonably has believed to be
         in or not opposed to the corporation's best interests. There shall be
         no indemnification in respect of any claim, issue, or matter as to
         which that person shall have been adjudged to be liable to the
         corporation, unless and only to the extent that the court in which such
         action or suit was brought shall determine upon application that,
         despite the adjudication of liability, but in view of all circumstances
         of the case, the person is fairly and reasonably entitled to indemnity
         for such expenses as the court considers proper. To the extent that a
         corporate director, officer, employee, or agent has 



                                       6
<PAGE>   7


         been successful on the merits or otherwise in defense of any action,
         suit or proceeding referred to in this Article X, or in defense of any
         claim, issue, or matter therein, such person shall be indemnified
         against expenses, including attorneys' fees, which that person actually
         and reasonably incurred in connection therewith. 

         2.       Unless ordered by a court of competent jurisdiction, the 
         corporation shall provide for any indemnification under this Article X,
         only as authorized in the specific case upon a determination that
         indemnification of the director, officer, employee, or agent is proper
         under the circumstances because such person has met the applicable
         standard of conduct set forth in this Article X. This determination
         shall be made by majority vote of a quorum of the Board of Directors or
         the shareholders.

         3.       The corporation may pay expenses incurred in defending a civil
         or criminal action, suit, or proceeding, in advance of the final
         disposition of the action, suit or proceeding upon receipt of an
         undertaking by or on behalf of the director, officer, employee, or
         agent that the amount advanced shall be repaid if it is ultimately
         determined that such person is not entitled to be indemnified by the
         corporation as authorized in this Article X. The indemnification and
         advancement of expenses provided by this Article shall not be exclusive
         of any other rights to which a person seeking indemnification or
         advancement of expenses may be entitled under any bylaw, agreement,
         vote of shareholders or disinterested directors, or otherwise, both as
         to action in that person's official capacity and as to action in
         another capacity while holding office.

         4.       The corporation may purchase and maintain insurance on behalf 
         of any person who is or was a corporate director, officer, employee, or
         agent, or is or was serving at the



                                       7

         corporation's request as a director, officer, employee, or agent,
         partnership, joint venture, trust, or other enterprise, against any
         liability asserted against such person and incurred by that person in
         any such capacity or arising out of that person 's status in any such
         capacity, whether or not the corporation would have the power to
         indemnify the person against the liability under the provisions of this
         Article.

         5.       Any indemnification or advancement of expense under this
         Article X shall, unless otherwise provided when the indemnification or
         advancement of expenses is authorized or ratified, continue as to a
         person who has ceased to be a director, officer, employee, or agent and
         shall inure to the benefit of such person's heirs, executors, personal
         representatives and administrators. 

         6.       A director shall not be liable to the corporation or its 
         shareholders for monetary damages for breach of fiduciary duty, except
         for: 
                  (a)      Any breach of the director's duty of loyalty to the
                  corporation or its shareholders;

                  intentional misconduct or a knowing violation of law; 
                  (c)      Actions under Section 16-10-44, Utah Code Annotated 
                  (1953), as amended; or 
                  (d)      Any transaction from which the director derived an
                  improper personal benefit.

     Notwithstanding the foregoing, in no event shall the corporation be
obligated to set aside for the redemption of shares of Class B Common stock any
amount in excess of the lesser of (i) the total redemption price of all shares
of Class B Common Stock then outstanding; or (ii) the maximum amount the
corporation is then permitted to expend in the purchase of its own shares as
provided in applicable law, including section 5 of the Utah Business Corporation
Act, or any successor provision.

                           (2) Each outstanding share of Class B Common Stock
not previously redeemed as provided in this paragraph I, and for which no
payments have been placed into the sinking Fund, shall be redeemed by the
corporation immediately upon the effectiveness of a registration statement under
the Securities Act of 1933, as amended, covering a firm-commitment
underwritten offer and sale of any Common Stock of the corporation to the public
for an aggregate consideration of at least 83,000,000. Such redemption shall be
effected by the corporation issuing to each of the holders of Class B Common
Stock its promissory note in a principal



                                       14
<PAGE>   15


amount equal to the issuance price of all of the shares of Class B Common Stock
to be redeemed for such holder (being all of the Shares of Class B Common Stock
not otherwise redeemed as provided in this paragraph I). interest shall accrue
on the principal amount of each promissory note at the rate of twelve percent
(12%) per annum, commencing from the date of the original issuance of the shares
being redeemed by the promissory note. The promissory notes shall be unsecured,
general obligations of the corporation, The entire principal amount and all
accrued interest under all such promissory notes issued to redeem outstanding
shares of Class B Common Stock shall be due and payable on the closing of the
public offering which triggered the redemption obligation.

                           (3) The mandatory redemption price (the "Redemption
Price") for each share of Class B Common Stock shall for purposes of a
redemption out of revenues provided in paragraph (I) (b)(l) above be: ii) an
amount in cash equal to 81.80 per share (subject to adjustment for stock splits
and the like), plus all declared but unpaid dividends thereon, to and including
the date fixed for redemption; or (ii) for purposes of a redemption by
promissory note triggered by a public offering of securities of the corporation
as provided in paragraph (I) (b)(2) above, an amount equal to the original
issuance price of the shares to be redeemed, plus all declared but unpaid
dividends thereon, with the entire redemption price earning interest at a simple
rate of twelve percent (12%) per annum, commencing from the date of redemption,
and the portion of the redemption price based on the original issuance price of
the shares earning such interest from the date of original issuance of the
shares.

                           (4) The cash in the Sinking Fund shall be used to
acquire by redemption, in the manner provided below, the maximum number of
shares of Class B Common Stock which ray be purchased out of the Sinking Fund at
the Redemption Price.

                           (5) Upon each cash redemption of outstanding shares
of Class B Common Stock, until all outstanding shares of Class B Common Stock
have been redeemed, the corporation shall effect such redemption pro-rata
according to the number of shares held by each holder of Class B Common Stock.

                           (6) Upon each Sinking Fund Payment Date, written
notice (the "Mandatory Redemption Notice") shall be mailed, postage prepaid, to
each holder of record of Class B Common Stock to be redeemed, at the post office
address last shown on the records of the corporation. The Mandatory Redemption
Notice shall state:



                                       15

be redeemed, and the percentage of all outstanding shares of Class B Common
Stock represented by that number;

                   (ii)  The number of shares of Class B Common Stock to be
redeemed from the holder to whom the notice is mailed;

                   (iii) The Redemption Price applicable to the shares to be
redeemed, and the date fined for the redemption, which shall be not more than 30
days after the date of sailing of the Mandatory Redemption Notice (the
"Mandatory Redemption Date"); and

                   (iv)  That the holder is to surrender to the corporation, in
the manner and at the place designated, such holder's certificate or certificate
representing the shares of Class B Common Stock to be redeemed.

                         In the event of a redemption of shares triggered by a
public offering of securities of the corporation, as provided in paragraph (2)
above, a Mandatory Redemption Notice shall be sent as provided above, specifying
that all remaining outstanding shares of Class B Common Stock are to be redeemed
or the terms and conditions set forth in paragraph (I) (b) (2).

                         (7) On or before or promptly after the Mandatory
Redemption Date, each holder of Class B Common Stock to be redeemed shall
surrender the certificate or certificates representing such shares to the
corporation, in the manner and at the place designated in the Mandatory
Redemption Notice, and thereupon the Redemption Price for such shares shall be
payable to the order of the person whose name appears on such certificate or
certificates as the owner thereof, and each surrendered certificate shall be
cancelled and retired. In the event less than all of the shares represented by
such certificate are redeemed, a new certificate shall be issued representing
the unredeemed shares.

                         (8) If the Mandatory Redemption Notice shall have been
duly given, and if on the Mandatory Redemption Date the Redemption Price is
either paid or made available for payment through the deposit arrangement
specified in subparagraph (i) below, or through the issuance of a promissory
note as contemplated by paragraph (I)(b)(2) above, then notwithstanding that the
certificates evidencing any of the shares of Class B Common Stock so called for
redemption shall not have been surrendered, the dividends with respect to such
shares shall cease to accrue after the Mandatory Redemption Date and all rights
with respect to such shares shall forthwith after the Mandatory Redemption Date
terminate, except only the right of the holders to receive the Redemption Price
without interest, or the issuance of 


                                       16
<PAGE>   17


a promissory note as contemplated by paragraph (2), as the case may be, upon
surrender of their certificate or certificates therefor.

                           (i) On or prior to the Mandatory Redemption Date, the
corporation shall deposit with any bank or trust company having a capital and
surplus of at least 8100,000,000 as a trust fund, a sun equal to the aggregate
Redemption Price of all shares of Class B Common Stock called for redemption and
not yet redeemed, with irrevocable instructions and authority to the bank or
trust company to pay, on or after the Redemption Date or prior thereto, the
Redemption Price to the respective holders upon the surrender of their share
certificates. From and after the date of such deposit, the shares so called for
redemption shall be redeemed. The deposit shall constitute full payment of the
shares to their holders, and from and after the date of the deposit the shares
shall be deemed to be no longer outstanding, and the holders thereof shall cease
to be shareholders with respect to such shares and shall have no rights with
respect thereto except the rights to receive from the bank or trust company
payment of the Redemption Price of the shares, without interest, upon surrender
of their certificates therefor. Any funds so deposited and unclaimed at the end
of one year from the Mandatory Redemption Date shall be released or repaid to
the corporation, after which the holders of shares called for redemption shall
be entitled to receive payment of the Redemption Price only from the
corporation.

              c. Optional Accelerated Redemption of Class B Common Stock. The
corporation may, at any time, at the option of the board of directors, redeem
all or any part of the outstanding shares of Class B Common Stock prior to the
mandatory redemption contemplated in paragraph (4) (b) above by setting aside in
the Sinking Fund funds in addition to those required to be set aside for the
redemption of Class B Common stock as provided in paragraph (4) (b) (1) above,
and following the same notification and purchase procedures applicable to a
mandatory redemption of shares of Class B Common Stock as set forth in paragraph
(4)(b) above and applicable to a redemption out of revenues. The purchase price
for shares acquired in such a redemption shall be the same Redemption Price
applicable to a redemption out of revenues as set forth in paragraph (4) (b) (3)
above. In case of a redemption of only a part of the Class B Common Stock
pursuant to this paragraph (4) (c), the corporation shall designate pro-rata the
shares to be redeemed, consistent with the requirements of paragraph (4) (b) (5)
above.
              d. Mandatory Redemption of Class C Redeemable Common Stock. The
class C Redeemable Common Stock (the "Class C Common


                                       17

Stock") shall be subject to mandatory redemption provisions identical to those
applicable to the Class B Common Stock as set forth in paragraph (b) above,
except that: (i) no contributions shall be made to any sinking Fund for the
redemption of Class C Common Stock until all shares of Class B Common Stock have
been redeemed; and (ii) the Redemption Price applicable to the Class C Common
Stock to be redeemed out of any funds placed in a Sinking Fund shall be such
multiple of the original issuance price of the Class C Common Stock as may be
fixed by the Board of Directors of the corporation.

                           (2)      Each joint owner of shares of Class B or 
Class C Common Stock shall be considered a "Class B or C Holder" of such shares.

                           (3)      A minor for whom shares of Class B or Class
C Common Stock are held pursuant to a Uniform Gifts to Minors Act or similar law
shall be considered a Class B or C Holder of such shares.

                           (4)      Unless otherwise specified, the term 
"person" means both natural persons and legal entities.

         d. Any purported transfer of shares of Class B or Class C Common Stock
not permitted hereunder shall be void and of no effect and the purported
transferee shall have no rights as a stockholder of the corporation and no other
rights against or with respect to the corporation. The corporation may, as a
condition to the transfer or the registration of transfer of shares of Class B
or Class C Common Stock to a purported Permitted Transferee, require the
furnishing of such affidavits or other proof as it may reasonable request to
establish that such transferee is a Permitted Transferee. The corporation shall
note on the certificates for shares of Class B and Class C Common Stock the
restrictions on transfer and registration of transfer imposed by this paragraph
5.

         6. Residual Rights. All rights accruing to the outstanding shares of
capital stock of the corporation not expressly provided for to the contrary
herein or in the corporation's bylaws shall be vested in the Common Stock.

B.     Preferred Stock

       The shares of Preferred Stock authorized by these Articles of
Incorporation may be issued from time to time in one or more series. To the
extent, that these Articles of Incorporation, as they may be amended, have not
established series of Preferred Stock and fixed the variations in the relative
rights and preferences between series of Preferred Stock, the Board of Directors
is hereby authorized to: (i) divide the Preferred Stock into series; (ii) fix
the number of shares constituting any series so established and the designation
of each such series; and (iii) fix and determine the relative rights and
preferences of the shares of any series so established, all in the manner and
within the limitations set forth in Section Is of the Utah Business corporation
Act (or any successor provision) as currently in effect or as it may hereafter
be amended.

       For any wholly unissued series of Preferred Stock, the Board of Directors
may change the designation of the series, the number of shares constituting the
series and the relative rights and preferences of the shares of such series, in
the manner and within the limitations set forth above.

       For any series of Preferred Stock having issued and outstanding shares,
the Board of Directors is hereby authorized to increase or decrease the number
of shares of such series when the number of shares of such series was originally
fixed by the Board, but such increase or decrease shall be subject to the
limitations and restrictions stated in the resolution of the Board of Directors
originally fixing the number of shares of such series. If the number of shares
of any series is so decreased, the decrease shall not reduce the number of
shares of such series below the number then issued and outstanding and the
shares constituting such decrease shall resume the status that they had prior to
the adoption of the resolution originally fixing the number of shares of such
series.

C.       Reclassification of Common Voting Stock

         Upon the effective date of this amendment of the Articles of
Incorporation, all shares of common voting stock the corporation was authorized
to issue immediately prior to such effective date shall be reclassified,
redesignated and reconstituted into an equal number of shares of Class A Common
Stock, and each outstanding share of common voting stock, $0.01 per value per
share, shall be reclassified, redesignated and reconstituted into one share of
Class A Common Stock, $0.01 per value per share.

D.       No Pre-emptive Rights

         No holder of shares of the Capital Stock of the corporation shall have
any pre-emptive rights to acquire additional shares of the corporation, whether
now or hereafter authorized.

                                       21

         THIRD: The amendment to the Articles of Incorporation set forth in the 
preceding paragraph was adopted by the shareholders of the corporation by
unanimous written consent effective as of February 28, 1992.

         FOURTH: Prior to the effectiveness of these Articles of Amendment, the
corporation had one class of stock outstanding, designated common voting stock
and having a par value of $0.01 per share. One million shares of common voting
stock were outstanding upon the adoption of the above described amendment to the
Articles of Incorporation, and all such shares were entitled to vote on the
amendment.

         FIFTH: The number of shares voted for the above referenced amendment
was one million and the number of shares voted against such amendment was zero.

         SIXTH: The amendment increases the number of shares the corporation is
authorized to issue, redesignates the previously authorized shares of common
voting stock as Class A Common Stock, increases the number of shares of Class A
Common Stock the corporation is authorized to issue, creates two new classes of
Common Stock designated as Class B Redeemable Common Stock and Class C
Redeemable Common Stock, fixes the rights, terms, limitations and restrictions,
of the Class B and Class C Common Stock, creates a class of Preferred Stock, and
authorizes the Board of. Directors to divide the Preferred Stock into series and
to determine the relative rights and preferences of the shares of any series so
established. The amendment does not effect a change in the amount of stated
capital of the corporation.

                              ARTICLES OF AMENDMENT

                        to the Articles of Incorporation

                                       of

                                KYZEN CORPORATION

                            -------------------------

                  Pursuant to the provisions of Section 16-10a-602 of the Utah
Revised Business Corporation Act, the undersigned corporation adopts the
following Articles of Amendment to its Articles of Incorporation:

                  First:  The name of the corporation is Kyzen Corporation (the
"Corporation").

                  Second:  The following new Article XII shall be added to the 
Corporation's Articles of Incorporation:

                                   ARTICLE XII
                  Series A Junior Participating Preferred Stock

                  Section 1. Designation and Amount. The shares of such series
shall be designated as "Series A Junior Participating Preferred Stock" (the
"Series A Preferred Stock") and the number of shares constituting the Series A
Preferred Stock shall be 100,000. 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 Series A 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 Series A Preferred Stock.

                  Section 2. 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 Series A Preferred Stock with respect to dividends, the
         holders of shares of Series A Preferred Stock, in preference to the
         holders of Common Stock, par value $.01 per share (the "Common Stock"),
         of the Corporation, and of any other junior stock, 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 Series A
         Preferred Stock, in an amount per share (rounded to the nearest cent)
         equal to the greater of (a) $1 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 


                                       24
<PAGE>   25


         all noncash 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
         Series A 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
         Series A 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 Series A 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 per share on the Series A 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 Series A 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 Series A 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 Series A 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 Series A Preferred Stock
         entitled to receive payment of a dividend or distribution declared
         thereon, which record date shall be not more than 60 days prior to the
         date fixed for the payment thereof.

                  Section 3.  Voting Rights.  The holders of shares of Series A
Preferred Stock shall have the following voting rights:

                  (A) Subject to the provision for adjustment hereinafter set
         forth, each share of Series A Preferred Stock shall entitle the holder
         thereof to 100 votes on all matters submitted to a vote of the
         stockholders of the Corporation. 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 number of votes per share to which
         holders of shares of Series A Preferred Stock were entitled immediately
         prior to such event shall be adjusted by multiplying such number 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) Except as otherwise provided herein, in any other
         Certificate of Designations creating a series of Preferred Stock or any
         similar stock, or by law, the holders of shares of Series A 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
         stockholders of the Corporation.

                  (C) Except as set forth herein, or as otherwise provided by
         law, holders of Series A Preferred Stock shall have no special voting
         rights and their consent shall not be required (except to the extent
         they are entitled to vote with holders of Common Stock as set forth
         herein) for taking any corporate action.

                  Section 4.        Certain Restrictions.

                  (A) Whenever quarterly dividends or other dividends or
         distributions payable on the Series A Preferred Stock as provided in
         Section 2 are in arrears, thereafter and until all accrued and unpaid
         dividends and distributions, whether or not declared, on shares of
         Series A 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 Series A 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 Series A Preferred Stock, except
                  dividends paid ratably on the Series A 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;


                                       26
<PAGE>   27


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

                      (iv)  redeem or purchase or otherwise acquire for
                  consideration any shares of Series A Preferred Stock, or any
                  shares of stock ranking on a parity with the Series A
                  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 4, purchase or otherwise acquire such
         shares at such time and in such manner.

                  Section 5.     Reacquired Shares. Any shares of Series A
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled 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, or in any other Certificate of
Designations creating a series of Preferred Stock or any similar stock or as
otherwise required by law.

                  Section 6.     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 Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
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 Series A
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
Series A Preferred Stock, except distributions made ratably on the Series A
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 


                                       27
<PAGE>   28


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 aggregate amount to which holders of shares of Series A 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.

                  Section 7.  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 Series A 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 Series A 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.

                  Section 8.  No Redemption. The shares of Series A Preferred
Stock shall not be redeemable.

                  Section 9.  Rank.  The Series A 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.

                  Section 10. Amendment. The Articles of Incorporation of the
Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series A 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 Series A Preferred Stock, voting
together as a single class.

                  Third: The amendments to the Corporation's Articles of
Incorporation contained in these Articles of Amendment were adopted by the Board
of Directors at a meeting duly called and held on January 15, 1999.

                  Fourth: The amendments to the Corporation's Articles of
Incorporation contained in these Articles of Amendment were adopted by the Board
of Directors without shareholder action, which was not required.
