                           CORE MATERIALS CORPORATION
                     1998 INFORMAL CASH PROFIT SHARING PLAN

          Core Materials has an informal cash profit sharing plan for its
management and salaried employees which is calculated as follows:

          A profit sharing pool is created after a reasonable return is provided
to stockholders.

          Annually, the Company's Board of Directors will establish thresholds
for Earnings Before Taxes ("EBT") to provide such return to the stockholders.

          A profit sharing pool will be created based upon percentages of EBT
above the thresholds which will be shared with the permanent salaried employees
in the form of profit sharing.

          A total profit sharing pool is limited to a maximum percentage of EBT
as established by the Board of Directors.

          The salaried profit sharing pool is split into two groups, an
"executive" group and a "salary" group. The executive group consists of the
chief Operating Officer, the Chief Financial Officer, the Vice President of
Sales and Marketing, the Controller and two other key management positions.

          The executive group shares in 40% of the pool while the remaining
salary group shares in 60% of the pool.

          Employees must have been employed as of December 31, 1998 to be
eligible to participate. There is no pro-rating for terminated employees.

          The Board of Directors reserves the right to change the plan annually.
