                                  INTRODUCTION

                 AN OPPORTUNITY TO PURCHASE AMCAST COMMON STOCK
                           THROUGH PAYROLL DEDUCTIONS

Amcast has agreed to make its payroll deduction facilities available to its
eligible employees to enable them to purchase Amcast common stock at market
prices current at the time of purchase, through individual monthly ShareBuilder
Plan accounts opened by such employees with Merrill Lynch, Pierce, Fenner &
Smith Incorporated (the "Broker").

The formal name of the plan is Amcast Industrial Corporation Employee
ShareBuilder Plan. This plan gives you an opportunity to become a stockholder,
and it provides you with a convenient and consistent way to supplement your own
personal savings plan.

This booklet summarizes the provisions of the plan. It explains in detail how
you become eligible, what you must do to participate and what the plan does for
you.

Please read the booklet carefully. You might want to share it with your family
as well. In that way, all of you will know how the plan works-both for today and
for the future.

                                     * * * * *


Participation in the plan is entirely voluntary and Amcast is making no
recommendations to its employees. You should know that there is no guarantee
under the plan against loss due to changes in stock-market prices. In seeking
the benefits of stock ownership, you must also accept the risks.

Amcast has reserved the right to discontinue use of its payroll deduction
facilities for this plan at any time it deems such action to be advisable in its
judgment.
