                          5.4  For any Year ending prior to the Effective Time,
                 the Corporation's independent public accountants shall
                 determine and report to the Committee the amount available for
                 the Plan for such Year as promptly as practicable following
                 completion of their audit of the accounts of the Corporation
                 for the purpose of certification of the financial statements
                 appearing in the annual report to shareholders of the
                 Corporation for the Year.  In such case, the date the
                 Corporation receives such accountants' report shall be the
                 "Determination Date" for purposes of this Plan.

                          5.5  For any Year ending after the Effective Time,
                 the chief financial officer of Duriron shall make a good faith
                 determination of the amount available for the Plan for such
                 Year, such determination to be made in accordance with
                 generally accepted accounting principles applied consistently
                 with the Corporation's past practice.  In such case, the date
                 on which Duriron publicly announces its results of operations
                 for the same period as such Year shall be the "Determination
                 Date" for purposes of this Plan.

                 4.  Sections 7.1 and 7.2 of the Plan are amended in their
entirety to read as follows:

                          7.1  Common Shares to be delivered in partial payment
                 of Bonuses shall be made available from authorized and
                 unissued stock (i) of the Corporation, in the case of shares
                 issued prior to the Effective Time, and (ii) of Duriron, in
                 the case of shares issued at or after the Effective Time.

                          7.2  (a)  The Common Share portion of the Long Term
                 Portion of the Bonus shall consist of the number of Common
                 Shares having an aggregate market value, determined as
                 provided in Section 7.2(c), equal to fifty percent (50%) of
                 the Key Executive's share of the Long Term Portion as
                 determined under Section 5.1.  Such Common Shares shall be
                 issued within 30 days after the determination of market value
                 per share in accordance with Section 7.2(c).  If payment of
                 Common Shares would require the delivery of a fractional
                 share, then in lieu of the fractional share the Corporation
                 shall pay to the Key Executive the cash value thereof.

                          (b)  After the Effective Time, no common shares of
                 the Corporation will be issued under the Plan, but instead
                 persons otherwise entitled to receive common shares of the
                 Corporation shall receive, under the same terms and
                 restrictions as would be applicable to the common shares of
                 the Corporation without regard to the Agreement and Plan of
                 Merger or the Merger, that number of shares of Duriron Common
                 Stock (rounded down to the next full share) determined by
                 multiplying the number of common shares of the Corporation
                 otherwise issuable by the Conversion Ratio.  For purposes of
                 the foregoing, the number of common shares of the Corporation
                 otherwise issuable shall be considered to be the quotient of
                 (i) fifty percent (50%) of the Key Executive's share of the
                 Long Term Portion of the Bonus, divided by (ii) the market
                 value per share of a share of Duriron Common Stock, determined
                 as provided in Section 7.2(c), divided by (iii) the Conversion
                 Ratio.

                          (c)  In the case of common shares of the Corporation
                 delivered prior to the Effective Time, market value per share
                 shall be determined by independent appraisers or such other
                 valuation methods as the Corporation may from time to time
                 adopt.  In the case of shares of Duriron Common Stock
                 delivered at or after the Effective Time, market value per
                 share shall be considered to be the average of the closing
                 sale prices of a share of Duriron Common Stock during the last
                 10 trading days ending on the Determination Date (or ending
                 immediately prior to the Determination Date if the
                 Determination Date is not a trading day), as reported on the
                 NASDAQ National Market.

                 5.  Section 10 of the Plan is amended by adding new Section
10.4 as follows:

                          10.4  In the event the Merger becomes effective, the
                 Plan shall terminate as of the beginning of business on
                 January 1, 1996; provided, however, that such termination
                 shall not affect entitlement to or payment of any Bonus earned
                 with respect to any Year ending prior to January 1, 1996.
