the attainment of the profit and growth objectives of Eagle-Picher Industries,
Inc. (the "Company") and its subsidiaries by providing incentive to key
executives whose management and individual performance have a direct impact on
achieving those objectives. The Plan also is expected to encourage the continued
employment of the Company's and its subsidiaries' key executives and to
facilitate the recruiting of executive personnel in the future. The Plan is not
intended to be an "employee pension benefit plan" within the meaning of Section
3 of the Employee Retirement Income Security Act of 1974, as amended ("ERISA").

          Section 2. Definitions. As used herein, the following terms shall have

outstanding debt of the Parent, the Company and its Subsidiaries owing to banks,
or owing with respect to securities issued by the Parent, the Company or by any
of its Subsidiaries and the aggregate liquidation preference of all outstanding

Committee announces in writing the award of the Units to a Participant.

been designated by a Participant in his or her most recent written beneficiary
designation filed with the Committee to receive the Participant's rights under
the Plan upon the Participant's death, or, if there is no such designation or no

have neither been forfeited nor exercised under the Plan as of such date, plus
(iii) the amount determined by the Committee pursuant to the second sentence of
Section 3(c); provided, however that on or before November 30, 1998, the Unit
Value of a Unit shall be $1.00.

         Section 3.  Administration.

         (a) The Committee shall be composed of three individuals each of whom
shall continue to serve until he resigns, dies or is Incapacitated. Initially,
the members of the Committee shall be Thomas E. Petry, Joel P. Wyler and Andries
Ruijssenaars. In the event that either Mr. Petry or Mr. Ruijssenaars shall
resign, die or be Incapacitated, the remaining members of the Committee shall
appoint his successor. In the event that Mr. Wyler shall resign, die, or be
Incapacitated, his successor shall be appointed by Granaria Holdings B.V.

         (b) The Plan shall be administered by and in the sole discretion of the
Committee which, by vote of a majority of the members, but only if Mr. Wyler (or
his successor appointed by Granaria Holdings, B.V.) is included in the majority,
may establish such rules and regulations as it deems necessary, make amendments
consistent with Section 10(d), make adjustments in the calculation of EBITDA and
Unit Value pursuant to Section 3(c), interpret the Plan and otherwise make all
determinations and take such action in connection with the Plan as it deems
appropriate.

         (c) From time to time, the Committee in its sole discretion may make
adjustments in the Company's consolidated earnings derived from operations
before interest, taxes, depreciation and amortization determined in accordance
with GAAP for purposes of calculating EBITDA so that changes in accounting
principles; extraordinary or unusual charges or credits; acquisitions, mergers,
consolidations, and other corporate transactions; and other elements or factors
influencing calculation of EBITDA do not distort or affect the operation of the
Plan in a manner inconsistent with the achievement of its purposes. From time to
time, the Committee in its sole discretion may increase the divisor for purposes
of calculating Unit Value to take into account any contribution to the equity
capital of the Company or any of its Subsidiaries or the proceeds of any
issuance of shares of equity capital by the Company or any of its Subsidiaries
and in its sole discretion may adjust any such increase to take into account
subsequent events.

         (d) The decisions of the Committee shall be final, conclusive, and
binding upon all parties. In administering the Plan, the Committee may employ
accountants and counsel (who may be the independent auditors and outside counsel
for the Company) and other persons to assist or render advice to it, all at the
expense of the Company.

         Section 4.  Eligibility.

         (a) The Committee shall designate those persons who shall be
Participants and shall award Units to each Participant.

         (b) The Committee shall record the award of Units in writing and shall
notify the affected Participant of such award in writing. Each award of Units to
a Participant shall be evidenced by a written agreement which shall contain such
provisions and be subject to any conditions or limitations as the Committee in
each instance shall deem appropriate and not

                                      -3-
<PAGE>   4

inconsistent with the provisions of this Plan. The Committee may at any time
award an additional number of Units to a Participant.

         Section 5.  Establishment of Units.

         (a) The Company hereby establishes an aggregate maximum of 5,000,000
participating shares in the Plan (the "Units"), each of which shall represent an
equal, undivided interest in the future appreciation in Capitalized Earnings
Value in accordance with the terms of this Plan.

         (b) The Units do not, in and of themselves, constitute a share of, nor
represent any ownership interest in, the Company. No Participant or Beneficiary
shall have any rights of a shareholder by virtue of an award of Units hereunder.
The Units represent, upon vesting and exercise as provided in Sections 6 and 7,
only the right to receive cash as provided in Section 8.

         (c) Any Units forfeited by a Participant pursuant to Section 6 or
Section 11(h) (or pursuant to the terms of the written agreement evidencing
their award) shall be available for subsequent award pursuant to this Plan to
other Participants.

         Section 6. Vesting. A Participant's rights to exercise Units shall vest
in accordance with this paragraph 6. One fifth of the Units awarded will vest on
each of the first five anniversaries of the Award Date. In the event that a
Participant ceases to be an employee of the Company or any Affiliate for any
reason other than by reason of death or being Incapacitated, any of the
Participant's Units that have not yet vested as of the date of such termination
of his employment shall be forfeited. By written notice to the Participant at
the time he is notified of the award, the Committee may determine to apply a
different vesting schedule to the Units awarded. The Units of a Participant who
dies or is Incapacitated while employed by the Company or any Affiliate shall be
immediately 100% vested as of the date of death or incapacity. The Units of a
Participant who is employed by the Company or any Affiliate on any Change of
Control Date shall be immediately 100% vested as of the Change of Control Date.
At any time, the Committee may accelerate the vesting schedule applicable to a
particular Participant by notifying the Participant in writing.

         Section 7.  Exercise of Rights.

         (a) Upon the exercise of the rights relating to vested Units, a
Participant will be entitled to receive payment for Net Appreciation of vested
Units pursuant to the terms of Section 8. Subject to Section 10(b), vested Units
may be exercised by the Participant at any time after the sixth anniversary of
the Award Date of such Units. On the date a Participant ceases, for any reason,
to be employed by the Company and any Affiliate other than by reason of death or
being Incapacitated, he shall forfeit all non-vested Units awarded to him. If
such employment is terminated for any reason other than for Misconduct as
defined in Section 11(h) herein, all vested but unexercised Units shall be
deemed to have been immediately exercised and the Exercise Date shall be the
date of termination of such employment.

                                      -4-
<PAGE>   5

         (b) Except in case the Participant ceases to be employed by the Company
or any Affiliate, the Participant must give written notice of any exercise of
rights with regard to vested Units to the Committee. Such written notice must be
given in the manner or form as the Committee may determine. In the event a
Participant wishes to exercise fewer than all of his vested Units, the notice of
exercise shall specify the number of Units that he wishes to exercise and (if
the Participant holds vested Units awarded at different times) the Award Date of
the Units he wishes to exercise. Any exercise of rights will be deemed to have
been made on the date such notice is received by the Committee (the "Exercise
Date").

         Section 8.  Payment for Units.

         (a) Upon exercise by a Participant of any vested Units, the Participant
will be entitled to payment for the number of vested Units exercised multiplied
by their Net Appreciation.

         (b) Payment for any exercised vested Units shall be made in cash in US
Dollars.

         (c) The Company or the Subsidiary that employs the Participant shall
pay the Participant the amount described in paragraph (a) of this Section 8
within 30 days after the later of the Exercise Date of the vested Units or the
date the Committee receives audited financial statements for the Company's most
recently ended fiscal year that ended on or prior to the Exercise Date.
Following such payment, the Company shall reduce on its records the total number
of Units held by the Participant by the number of Units so exercised.

         (d) No Participant shall be obligated to make any payments to the
Company in the event that the Net Appreciation of his Units at any time is less
than zero.

         (e) If a Participant dies or becomes Incapacitated while the
Participant is employed by the Company or any of its Affiliates, all Units of
the Participant not previously exercised shall be deemed exercised as of the
date of such death or incapacity (which shall be the Exercise Date).

         Section 9.  Designation of Beneficiaries.

         (a) Each Participant shall file with the Committee a written
designation of one or more persons or trusts as the Beneficiary who shall be
entitled to receive the amount, if any, payable under the Plan upon his death. A
Participant may, from time to time, revoke or change his Beneficiary designation
without the consent of any prior Beneficiary by filing a new designation with
the Committee. The last such designation received by the Committee shall be
controlling; provided, however, that no designation, or change or revocation
thereof, shall be effective unless received by the Committee prior to the
Participant's death, and in no event shall it be effective as of a date prior to
such receipt.

         (b) If the Committee is in doubt as to the right of any person to
receive such amount, the Committee may retain such amount, without liability for
any interest thereon, until the rights thereon are determined, or the Committee
may pay such amount into any court of appropriate

                                      -5-
<PAGE>   6


jurisdiction and such payment shall be a complete discharge of the liability of
the Plan, the Company, and the Committee therefor.

         Section 10.  Conversion and Termination

         (a) In the event that a class of common stock of either the Company or
of any corporation of which the Company is a Subsidiary shall be or become
publicly traded on a securities exchange in the United States or listed on the
NASDAQ National Market System, the Committee may, in its discretion, convert all
awards of Units then outstanding into equivalent options to purchase such
publicly traded common stock; provided, however, that with respect to each
Participant, as of the date of such conversion, the excess of the aggregate fair
market value of all the shares of common stock subject to the Participant's
purchase option (as measured by the closing trading price on the trading day
immediately preceding the date of conversion) over their option exercise price
shall be at least equal to the aggregate Net Appreciation of the Units held by
the Participant immediately before the conversion.

         (b) No Unit shall be exercisable after the tenth anniversary of the
Award Date of the Unit; any Unit not exercised on or before the tenth
anniversary of the Award Date of the Unit shall be forfeited.

         Section 11.  Miscellaneous.

         (a) Nothing in the Plan shall confer upon any Participant the right to
continue in the employ of, or to continue as a director of the Company, or any
Affiliate, as the case may be, or to be entitled to any remuneration or benefits
not set forth in the Plan or to interfere with or limit in any way the right of
the Company or any Affiliate to terminate such Participant's employment or
directorship.

         (b) The Company and any Affiliate are authorized to withhold from any
payment of cash with respect to Units under the Plan, amounts of withholding and
other taxes due in connection with such payment, and to take such other action
as the Committee may deem advisable to enable the Company and a Participant to
satisfy obligations for the payment of withholding taxes and other tax
obligations relating to any Unit or payment with respect to any Unit.

         (c) The Committee may at any time and from time to time alter, amend,
suspend, or terminate the Plan in whole or in part. Notwithstanding the
foregoing, no amendment shall affect adversely any of the rights of any
Participant without such Participant's consent.

         (d) Except as provided in Section 4, no person shall have any claim to
Units under the Plan. The Units are not shares in the Company and do not
represent any ownership interest in the Company. No Participant or Beneficiary
shall have any rights of a shareholder by virtue of an award of Units hereunder.
Participants shall have no rights as a stockholder. The Plan is for the benefit
of the Participants and their Beneficiaries and not for the benefit of any other
person.

                                      -6-
<PAGE>   7

         (e) Neither the Units nor any interest in Units shall be subject in any
manner to anticipation, alienation, pledge, transfer, or assignment, except by
will or by the laws of descent and distribution or with the written consent of
the Committee, and any attempt to so anticipate, alienate, pledge, transfer, or
assign shall be void and the interest of the Participant in such Units shall be
forfeited.

         (f) Neither the granting of nor any payout of Units under the Plan
shall limit a Participant's right to receive, or to be eligible for, any other
compensation or benefits from the Company.

         (g) Awards and payouts of Units will not be considered as compensation
for the purpose of computing employee contributions or benefits under the
Company's retirement, pension, thrift, group life insurance or other employee
benefit plan.

         (h) In the event a Participant's employment is terminated for
"Misconduct," then all his vested Units shall be forfeited. The term
"Misconduct" shall mean (i) repeated or prolonged failure to report for work
after written warning by the Company or any of its Subsidiaries other than due
to illness or authorized leave of absence; (ii) conviction of a felony; (iii) an
act of fraud, embezzlement or dishonesty; (iv) deliberate and intentional
violation of the material policies or procedures of the Company; or (v)
deliberate and intentional disregard of direct instructions from the Company's
executive officers or the Board of Directors.

         (i) Any payment by the Company shall be from the general funds of the
Company. No special or separate fund shall be established or other segregation
of assets made to assure any cash payment by the Company under the Plan. No
Participant or other person shall have under any circumstances any interest
whatever in any particular property or assets of the Company.

         (j) If any provision of the Plan shall be determined to be illegal and
unenforceable by any court of law, the remaining provisions shall be severable
and enforceable in accordance with their terms.

         (k) This Plan and all determinations made and actions taken pursuant
hereto shall be governed by the laws of the State of Ohio.

         Section 11.  Effective Date.  The Plan shall be effective as of       
May 5 , 1998.
