                                  SECTION 1
                            DESIGNATION AND AMOUNT

                The shares of such series shall be designated as "Series A

        constituting such series shall be 150,000.
        

                                  SECTION 2
                         DIVIDENDS AND DISTRIBUTIONS


                (A)     Subject to the prior and superior rights of the 
        holders of any shares of any series of Preferred Stock ranking prior and
        superior to the shares of Series A Junior Participating Preferred Stock
        with respect to dividends, the holders of shares of Series A Junior
        Participating Preferred Stock shall be entitlted 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 last 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 Divident Payment Date
        
        
   2
         after the first issuance of a share or a fraction of a share of Series
         A Junior Participating Preferred Stock, in an amount per share
         (rounded to the nearest cent) equal to the greater of (a) $37.50 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
         Series A Junior Participating Preferred Stock. In the event the
         Corporation shall at any time after December 4, 1990 (the "Rights
         Declaration Date") (i) declare any dividend on Common Stock payable in
         shares of Common Stock, (ii) subdivide the outstanding Common Stock,
         or (iii) combine the outstanding Common Stock into a smaller number of
         shares, then in each such case the amount to which holders of shares
         of Series A Junior Participating 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 immediatley 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 Junior Participating Preferred Stock as
         provided in the preceding paragraph immediatley 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 $37.50
         per share on the Series A Junior Participating 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 Junior Participating Preferred Stock
         from the Quarterly Dividend Payment Date next preceidng the date of
         issue of such shares of Series A Junior Participating Preferred Stock,
         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 
                




                                     -2-

        determination of holders of shares of Series A Junior Participating
        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 Junior
        Participating 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 Junior
        Participating Preferred Stock entitled to receive payment of a dividend
        or distribution declared thereon, which record date shall be no more
        than 30 days prior to the date fixed for the payment thereof.
        
                                  SECTION 3
                                VOTING RIGHTS

                The holders of shares of Series A Junior Participating
        Preferred Stock shall have the following voting rights:
        
                (A)     Subject to the provision for adjustment hereinafter set
        forth, each share of Series A Junior Participating Preferred Stock
        shall entitle the holder thereof to one hundred votes on all matters
        submitted to a vote of the stockholders of the Corporation.  In the
        event the Corporation shall at any time after the Rights Declaration
        Date (i) declare any dividend on Common Stock payable in shares of
        Common Stock, (ii) subdivide the outstanding Common Stock or (iii)
        combine the outstanding Common Stock into a smaller number of shares,
        then in each such case the number of votes per share to which holders
        of shares of Series A Junior Participating 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)     In addition to such voting rights as may from time to
        time be required by the laws of Nevada, the holders of Series A Junior
        Participating Preferred Stock shall vote at such times and in a like
        manner as holders of Common Stock may vote, one hundred votes for each
        share of Series A Junior Participating Preferred Stock held, and all
        shares of the Corporation shall be voted as a single class, except
        where specifically required by law to vote separately.

                (A)     Whenever quarterly dividends or other dividends
         or distributions payable on the Series A Junior Participating
         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 Junior Participatig Preferred
         Stock outstanding shall have been paid in full, the Corporation shall
         not:

                        (i)     declare or pay dividends on, make any
              other distributions on (other than dividends or distributions
              in shares of stock junior to the Series A Junior Participating
              Preferred Stock), or redeem or purchase or otherwise acquire for
              consideration any shares of stock ranking junior (either as to
              dividends or upon liquidation, dissolution or winding up) to the
              Series A Junior Participating Preferred Stock;


                        (ii)    declare or pay dividends on or make any
              other distributions on (other than dividends or distributions
              in shares of stock junior to the Series A Junior Participating
              Preferred Stock) any shares of stock ranking on a parity (either
              as to dividends or upon liquidation, dissolution or winding up)
              with the Series A Junior Participating Preferred Stock, except
              dividends paid ratably on the Series A Junior Participating
              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)   except as permitted by subparagraph
              (iv)  immediately below, redeem or purchase or otherwise
              acquire for consideration shares of any stock ranking on a parity
              (either as to dividends or upon liquidation, dissolution or
              winding up) with the Series A Junior Participating Preferred
              Stock, provided that the Corporation may at any time redeem,
              purchase or otherwise acquire shares of any such parity 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 Junior Participating Preferred
              Stock; or

              any shares of Series A Junior Participating Preferred Stock, or
              any shares of stock ranking on a parity with the Series A Junior
              Participating 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 Junior Participating 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 to be created by
         resolution or resolutions of the Board of Directors, subject to the
         conditions and restrictions on issuance set forth herein.

                                       SECTION 6
                        LIQUIDATION, DISSOLUTION OR WINDING UP

              (A)   Upon any liquidation (voluntary or otherwise),
         dissolution or winding up of the Corporation, no distribution shall be
         made to the holders of shares of stock ranking junior (either as to
         dividends or upon liquidation, dissolution or winding up) to the
         Series A Junior Participating Preferred Stock unless, prior thereto,
         the holders of shares of Series A Junior Participating Preferred Stock
         shall have received the greater of (a) $1,500.00 per share, plus an
         amount equal to accrued and unpaid dividends and distributions thereon,
         whether or not declared, to the date of such payment or (b) an 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 Common Stock. In the event the Corporation shall
         at any time after the Rights Declaration Date (i) declare any dividend
         on Common Stock payable in shares of Common Stock, (ii) subdivide the
         outstanding Common Stock, or (iii) combine the outstanding Common
         Stock into a smaller number of shares, then in each such case the




                                          -5-

         amount to which holders of shares of Series A Participating Junior
         Preferred Stock were entitled immediately prior to such event pursuant
         to 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) In the event, however, that there are not sufficient assets
         available to permit payment in full of the Series A liquidation
         preference and the liquidation preferences of all other series of
         Preferred Stock, if any, which rank on a parity with the Series A
         Junior Participating Preferred Stock, then such assets shall be
         distributed ratably to the holders of such parity shares in proportion
         to their respective liquidation preferences.

                                  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 the shares of
         Series A Junior Participating 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 after the Rights Declaration
         Date (i) declare any dividend on Common Stock payable in shares of
         Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
         combine the outstanding Common Stock into a smaller number of shares,
         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 Junior
         Participating 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.

                             OPTIONAL REDEMPTION

                (A)  The Corporation shall have the option to redeem the whole
         or any pat of the Series A Junior Participating Preferred Stock at any
         time at a redemption price equal to the greater of (x) $1,500.00 per
         share or (y) 100 times the "current per share market price" of the
         Common Stock on the date of the mailing of the notice of redemption,
         plus unpaid accumulated dividends to the date of such redemption. In
         the event the Corporation shall at any time after the Rights
         Declaration Date, (i) declare any dividend on Common Stock, payable in
         shares of Common Stock, (ii) subdivide the outstanding Common Stock or
         (iii) combine the outstanding Common Stock into a smaller number of
         shares, then in each such case the amount to which holders of shares   
         of Series A Junior Participating Preferred Stock were otherwise
         entitled immediately prior to such event 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. The
         "current per share market price" on any date shall be deemed to be the
         average of the closing price per share of such Common Stock for the 10
         consecutive Trading Days (as such term is hereinafter defined)
         immediately prior to such date. The closing price for each day shall
         be the last sale price, regular way, or, in case no such sale takes
         place on such day, the average of the closing bid and asked prices,
         regular way, in either case as reported in the principal consolidated
         transaction reporting system with respect to securities listed or
         admitted to trading on the New York Stock Exchange or, if the Common
         Stock is not listed or admitted to trading on the New York Stock
         Exchange, as reported in the principal consolidated transaction
         reporting system with respect to securities listed or admitted to
         trading on the principal national securities exchange on which the
         Common Stock is listed or admitted to trading or, if the Common Stock
         is not listed or admitted to trading on any national securities
         exchange, the last quoted price or, if not so quoted the average of
         the high bid and low asked prices in the over-the-counter market, as
         reported by the National Association of Securities Dealers, Inc.
         Automated Quotation System or such other system then in use or, if on
         any such date the Common Stock is not quoted by any such organization,
         the average of the closing bid and asked prices as furnished by a
         professional market maker making a market in the Common Stock selected
         by the Board of Directors of the Corporation. If on such date no such
         market maker is making a market in the Common Stock, the fair value of
         the Common Stock on such date as determined in good faith by the Board
         of Directors of the Corporation shall be used. The term "Trading Day"
         shall mean a day on which the principal



                                     -7-
   8
         national securitites exchange or association on which the Common Stock
         is listed or admitted to trading is open for the transaction of
         business or, if the Common Stock is not listed or admitted to trading
         on any national securities exchange association, a Monday, Tuesday,
         Wednesday, Thursday or Friday on which banking institutions in the
         State of Texas are not authorized or obligated by law or executive
         order to close.

                (B)     Notice of any such redemption shall be given by mailing
         to the holders of the Series A Junior Participating Preferred Stock a
         notice of such redemption, first class postage prepaid, not later than
         the thirtieth day and not earlier than the sixtieth day before the
         date fixed for redemption, at their last address as the same shall
         appear upon the books of the Corporation. Any notice which is mailed
         in the manner herein provided shall be conclusively presumed to have
         been duly given, whether or not the shareholder received such notice,
         and failure duly to give such notice by mail, or any defect in such
         notice to any holder of Series A Junior Participating Preferred Stock
         shall not affect the validity of the proceedings for the redemption of
         such Series A Junior Participating Preferred Stock.
               
                (C)     If less than all the outstanding shares of the Series A
         Junior Participating Preferred Stock are to be redeemed, the number of
         shares to be redeemed shall be determined by the Board of Directors
         and the shares to be redemmed shall be determined by lot or pro rata
         or in such other fair and equitable manner as may be prescribed by
         resolution of the Board of Directors.

                (D)     The notice of redemption to each holder of Series A
         Junior Participating Preferred Stock shall specify (a) the number of
         shares of Series A Junior Participating Preferred Stock of such holder
         to be redeemed, (b) the date fixed for redemption, (c) the redemption
         price and (d) the place of payment of the redemption price.

                (E)     If any such notice of redemption shall have been duly
         given or if the Corporation shall have given to the bank or trust
         company hereinafter referred to irrevocable written authorization
         promptly to give or complete such notice, and if on or before the
         redemption date specified therein the funds necessary for such
         redemption shall have been deposited by the Corporation with the bank
         or trust company designated in such notice, doing business in the
         United States of America and having a capital surplus and undivided
         profits aggregating at least $25,000,000 according to its last
         published statement of condition, in trust for the benefit of the
         holders of Series A Junior Participating Preferred Stock called for
         redemption, then, notwithstanding that any certificate for such share
         so called for redemption



                                     -8-

         shall not have been surrendered for cancellation, from and after the
         time of such deposit all such shares called for redemption shall no
         longer be deemed outstanding and all rights with respect to such
         shares shall no longer be deemed outstanding and all rights with
         respect to such shares shall forthwith cease and terminate, except the
         right of the holders thereof to receive from such bank or trust company
         at any time after the time of such deposit the funds so deposited,
         without interest, and the right to exercise, up to the close of
         business on the fifth day before the date fixed for redemption, all
         privileges of conversion or exchange, if any. In case less than all
         the shares represented by any surrendered certificate are redeemed, a
         new certificate shall be issued representing the unredeemed shares.
         Any interest accrued on such funds shall be paid to the Corporation
         from time to time. Any funds so deposited and unclaimed at the end of
         six years from such redemption date shall be repaid to the
         Corporation, after which the holders of shares of Series A Junior
         Participating Preferred Stock called for redemption shall look only to
         the Corporation for payment thereof; provided that any funds so
         deposited which shall not be required for redemption because of the
         exercise of any privilege of conversion or exchange subsequent to the
         date of deposit shall be repaid to the Corporation forthwith.

                                       SECTION 9
                                        RANKING

              The Series A Junior Participating Preferred Stock shall rank
         junior to all other series of the Corporation's Preferred Stock as to
         the payment of dividends and the distribution of assets, unless the
         terms of any such series shall provide otherwise.

                                      SECTION 10
                                       AMENDMENT

              So long as any share of Series A Junior Participating Preferred
         Stock are outstanding, the Articles of Incorporation of the
         Corporation shall not be further amended in any manner which would
         materially alter or change the powers, preferences or special rights
         of the Series A Junior Participating Preferred Stock so as to affect
         them adversely without the affirmative vote of the holders of a
         majority or more of the outstanding shares of Series A Junior
         Participating Preferred Stock, voting separately as a class.

                Series A Junior Participating Preferred Stock may be issued in
        fractions of a share which shall entitle the holder, in proportion to
        such holders' fractional shares, to exercise voting rights, receive
        dividends, participate in distributions and to have the benefit of all
        other rights of holders of Series A Junior Participating Preferred      
        Stock.
        
        IN WITNESS WHEREOF, we have executed and subscribed this Certificate
and do affirm the foregoing as true under penalties of perjury as of this 6th
