               WHEREAS, the Issuer expects Eagle-Picher Industries, Inc., an
Ohio corporation (the "Company") to have adopted the Incentive Stock Plan of
Eagle-Picher Industries, Inc. (the "Plan") substantially in the form attached
hereto as Annex A for the benefit of Participants and their Beneficiaries under
such Plan, and

               WHEREAS, the Issuer and the Trustees agree to the terms and
conditions of this Trust Agreement; and intend that the Company shall be bound

of Participants and their Beneficiaries under the Plan, to be known as the
Eagle-Picher Management Trust (the "Trust"), consisting of the cash transfer
made this day to the Trust by the Issuer and such contributions as shall be
received by the Trustees from the Company in accordance with the provisions of
the Plan. The Trust is not intended to be a tax-exempt entity under Section
501(a) of the Internal Revenue Code. The Trustees shall receive such
contributions and transfers in Trust and, except as provided herein, shall hold
and administer the same as a single Trust fund, shall invest and reinvest the
same and the income therefrom, without distinction between principal and income,
and shall pay over and distribute the net income therefrom and the principal
thereof in accordance with the provisions of the Plan upon written direction of
the Committee.

               1.2 Effective Date. The effective date of this Trust is February

               2.1 Receipt of Payments. The Company may from time to time
remit contributions under the Plan to the Trustees. Such contributions, together
with any income thereon, shall be held in trust on behalf of Participants and
their Beneficiaries.

and actually incurred by the Trustee in the administration of this Trust,
including but not limited to accounting, consulting and legal expenses, or such

upon the Trust Fund, and the Trustee is authorized to withdraw such amounts from
the Trust after 60 days of presentation of a statement of amounts due, unless
the Company or the Issuer pays such amount within the 60 day period after
presentation.

               3.5 Tenure in Office. Any Trustee may resign upon written
notice to the other Trustees. If any Trustee resigns, dies, or becomes
