         Brush Wellman Inc., an Ohio corporation, hereby adopts this Amendment
No. 5 to the Brush Wellman Inc. Supplemental Retirement Benefit Plan (December

         Section 3.1 of the Plan is amended to provide as follows:

         Section 3.1 - Retirement Benefit

                  If a Participant whose employment with the Company and all
         Related Companies terminates for any reason other than his death after
         he has 5 or more Years of Vesting Service and either the first day of
         the calendar month following his attainment of age 55 shall have
         occurred on or before the date his employment terminated or he survives
         until the first day of the calendar month following his attainment of
         age 55, such Participant shall be eligible for a retirement benefit
         under the Plan in the amount, if any, provided in Section 4.1.

                                       II.

         Section 3.2 of the Plan is amended to provide as follows:

         Section 3.2 - Spouse Death Benefit

                  If either (i) a Participant who has 5 or more Years of Vesting

         the employment of a Participant who has 5 or more Years of Vesting
         Service with the Company and all Related Companies has terminated for
         any reason other than his death and the Participant dies prior to the
         first day of the calendar month following the calendar month in which
         either he attains or would have attained age 55, and, in either case,
         the Participant's death occurs under circumstances that entitle the
         Participant's Spouse to a pre-retirement surviving spouse pension under
         the Brush Pension Plan, the TMI Pension Plan, and/or the WAM Pension
         Plan, such Participant's Spouse shall be eligible for a death benefit
