      The Plan is administered by the Committee. In addition to any other powers

            (a)   to construe and interpret the Plan;

            (b)   to  establish,   amend  and  rescind   appropriate  rules  and
                  regulations  relating to the Plan;

                  and expiration date applicable to each Award;

            (d)   to contest on behalf of the  Company or  Participants,  at the

                  relating to the Plan or to any Awards;

            (e)   generally,  to administer the Plan, and to take all such steps
                  and make all such  determinations  in connection with the Plan
                  and the Awards granted  thereunder as it may deem necessary or
                  advisable;

            (f)   to determine  the form in which  payment of a SAR or a Phantom
                  Stock Award granted hereunder will be made (i.e., cash, Common
                  Stock or a combination  thereof) or to approve a Participant's
                  election to receive cash in whole or in part in  settlement of
                  the SAR or Phantom Stock Award; and


            (g)   to determine the form in which tax  withholding  under Section
                  16 of this Plan will be made (i.e.,  cash,  Common  Stock or a
                  combination thereof).

5.    Eligible Employees

      Subject to the  provisions of the Plan,  the Committee  shall from time to
time select those key  employees of the Company and any  subsidiary or affiliate
of the Company who shall be designated as Participants  and the number,  if any,
of ISOs,  SARs,  Restricted  Stock,  Phantom Stock and NSOs, or any  combination
thereof,  to be awarded to each such  Participant;  provided,  however,  that no
ISOs,  or SARs  granted with  respect to ISOs,  shall be awarded  under the Plan
after the  expiration  of the  period  of ten  years  from the date this Plan is
adopted by the Board.

6.    Terms and Conditions of Incentive Stock Options

      Each ISO agreement, in such form as is approved by the Committee, shall be
subject to the following  express terms and  conditions  and to such other terms
and  conditions,  not  inconsistent  with the Plan,  as the  Committee  may deem
appropriate:

            (a)   Option Period.  Each ISO will expire as of the earliest of:

                (i)   the date on which it is forfeited under the
provisions of Section 12;

                (ii)  ten years (or five years as specified in paragraph
(d) below) from the Award Date;

                (iii) three (3) months after the Participant's termination
of employment with the Company and its parent and subsidiaries for any reason
other than death;

                (iv)  twelve (12) months after the Participant's death; or

                (v)   any other date (within the limits of the Code)
specified by the Committee when the ISO is granted.

            (b) Option Price.  Subject to the provisions of paragraph (d) below,
the Option  Price shall be  determined  by the  Committee  at the time an ISO is
granted, and shall not be less than the Fair Market Value of the Common Stock on
the Award Date.

            (c) Other Option Provisions.  The form of ISO authorized by the Plan
may contain  such other  provisions  as the  Committee  may,  from time to time,
determine; provided, however, that such other provisions may not be inconsistent
with any requirements  imposed on incentive stock options under Code Section 422
and related Treasury regulations.


            (d) Awards to Certain Stockholders.  Notwithstanding  paragraphs (a)
and (b) above, if an ISO is granted to a Participant who, immediately before the
grant of the ISO,  owns  stock  representing  more than 10  percent of the total
combined  voting  power of all  classes of stock of the Company or its parent or
subsidiary  corporations,  the exercise period specified in the option agreement
for which the ISO  thereunder  is granted  shall not exceed  five years from the
Award  Date,  and the  Option  Price  shall be at least 110  percent of the Fair
Market Value (as of the Award Date) of the stock subject to the ISO.

7.    Terms and Conditions of Nonqualified Stock Options

      Each NSO agreement, in such form as is approved by the Committee, shall be
subject to the following  express terms and  conditions  and to such other terms
and  conditions,  not  inconsistent  with the Plan,  as the  Committee  may deem
appropriate:

            (a)   Option Period.  Each NSO will expire as of the earliest of:

             (i)       the date on which it is forfeited under the
provisions of Section 12;

             (ii)      three (3) months after the Participant's termination
of employment with the Company and its parent and subsidiaries for any reason
other than death;

             (iii)     twelve (12) months after the Participant's death; or

             (iv)      any other date specified by the Committee when the
NSO is granted.

            (b) Option Price.  At the time granted,  the Board of Directors will
fix the Option Price,  which will be no less than  eighty-five  percent (85%) of
the Fair Market Value of the shares subject to the NSO on the Award Date.

            (c) Other Option Provisions.  The form of NSO authorized by the Plan
may  contain  such  other  provisions  as the  Committee  may from  time to time
determine.


8.    Terms and Conditions of Stock Appreciation Rights

      The  Committee  may, in its  discretion,  grant an SAR to any  Participant
under the Plan. Each SAR shall be evidenced by an agreement  between the Company
and the Participant, and may relate to and be associated with all or any part of
a  specific  ISO or NSO.  An SAR shall  entitle  the  Participant  to whom it is
granted  the  right,  so long as such SAR is  exercisable  and  subject  to such
limitations  as  the  Committee  shall  have  imposed,  to  surrender  any  then
exercisable  portion of his SAR and, if  applicable,  the related ISO or NSO, in
whole or in part, and receive from the Company in exchange,  without any payment
of cash  (except for  applicable  employee  withholding  taxes),  that number of
shares of Common  Stock  having an  aggregate  Fair Market  Value on the date of
surrender  equal to the product of (i) the excess of the Fair Market  Value of a
share of Common Stock on the date of surrender over the Fair Market Value of the
Common Stock on the date the SARs were issued, or, if the SARs are related to an
ISO or an NSO,  the per share  Option  Price  under such ISO or NSO on the Award
Date, and (ii) the number of shares of Common Stock subject to such SAR, and, if
applicable, the related ISO or NSO or portion thereof which is surrendered.

      An SAR granted in  conjunction  with an ISO or NSO shall  terminate on the
same date as the  related ISO or NSO and shall be  exercisable  only if the Fair
Market Value of a share of Common Stock exceeds the Option Price for the related
ISO or NSO, and then shall be exercisable to the extent, and only to the extent,
that the related ISO or NSO is  exercisable.  The  Committee  may at the time of
granting any SAR add such additional conditions and limitations to the SAR as it
shall deem advisable,  including,  but not limited to, limitations on the period
or periods within which the SAR shall be  exercisable  and the maximum amount of
appreciation  to be  recognized  with  regard to such SAR. If a  Participant  is
subject to Section  16(a) and Section  16(b) of the Exchange  Act, the Committee
may at any time add  such  additional  conditions  and  limitations  to such SAR
which, in its  discretion,  the Committee deems necessary or desirable to comply
with such Section  16(a) or Section 16(b) and the rules and  regulations  issued
thereunder,  or to obtain  any  exemption  therefrom.  Any ISO or NSO or portion
thereof which is  surrendered  with an SAR shall no longer be  exercisable.  The
Committee,  in its sole discretion,  may allow the Company to settle all or part
of the Company's obligation arising out of the exercise of an SAR by the payment
of cash equal to the  aggregate  Fair Market Value of the shares of Common Stock
which the Company would otherwise be obligated to deliver.

9.    Terms and Conditions of Restricted Stock Awards

      All  shares of Common  Stock  awarded  to  Participants  under the Plan as
Restricted Stock shall be subject to the following  express terms and conditions
and to such other terms and conditions,  not inconsistent  with the Plan, as the
Committee shall deem appropriate:

            (a)  Restricted  Period.  Shares  of  Restricted  Stock  awarded  to
Participants  may not be  sold,  assigned,  transferred,  pledged  or  otherwise
encumbered before they vest. Subject to the provisions of paragraphs (b) and (d)
below and any other restrictions  imposed by law, any shares of Restricted Stock
that vest will be  transferred,  subject only to the  restrictions  set forth in
Section 20, to the Participant or, in the event of his death, to the beneficiary
or  beneficiaries  designated  by  writing  filed  by the  Participant  with the
Committee  for such  purpose or, if none,  to his estate.  Delivery of shares in
accordance  with the  preceding  sentence  shall be made  within the  thirty-day
period after they vest.


            (b) Forfeitures.  A Participant shall forfeit all unpaid accumulated
dividends and all shares of Restricted  Stock which have not vested prior to the
date that his employment with the Company is terminated for any reason.

            (c) Certificates  Deposited With Company. Each certificate issued in
respect of shares of Restricted Stock awarded under the Plan shall be registered
in the name of the  Participant  and  deposited  with  the  Company.  Each  such
certificate shall bear the following (or a similar) legend:

            "The  transferability  of this  certificate  and the shares of stock
represented   hereby  are  subject  to  the  terms  and  conditions   (including
forfeiture)  relating to Restricted  Stock contained in the AMCOL  International
Corporation 1993 Stock Plan and an Agreement entered into between the registered
owner and AMCOL International Corporation. Copies of such Plan and Agreement are
on file at the principal office of AMCOL International Corporation."

            (d) Stockholder Rights. Subject to the foregoing restrictions,  each
Participant  shall  have all the  rights of a  stockholder  with  respect to his
shares of Restricted Stock including,  but not limited to, the right to vote and
to receive dividends on such shares.

10.   Terms and Conditions of Phantom Stock

      The  Committee  may,  in  its  discretion,  award  Phantom  Stock  to  any
Participant under the Plan. Each Award of Phantom Stock shall be evidenced by an
agreement  between the Company and the  Participant.  An Award of Phantom  Stock
shall entitle the  Participant to whom it is awarded the right to elect, so long
as such Phantom Stock is vested and subject to such limitations as the Committee
shall have imposed,  to surrender any then vested  portion of the Phantom Stock,
in whole or in part,  and  receive  from the  Company in  exchange  for the Fair
Market Value of the Common Stock to which the surrendered Phantom Stock relates,
payable  either  in cash or in  shares  of  Common  Stock as the  Committee  may
determine.  The Committee may at the time of awarding any Phantom Stock add such
additional  conditions  and  limitations  to the Phantom  Stock as it shall deem
advisable,  including,  but not limited to, limitations on the period or periods
within which the Phantom  Stock may be  surrendered,  and the maximum  amount of
appreciation to be recognized with regard to such Phantom Stock.

11.   Manner of Exercise of Options

      To exercise an Option in whole or in part, a  Participant  (or,  after his
death, his executor or administrator) must give written notice to the Committee,
stating  the number of shares with  respect to which he intends to exercise  the
Option.  The Company  will issue the shares with  respect to which the Option is
exercised upon payment in full of the Option Price. The Committee may permit the
Option  Price  to be  paid  in  cash  or  shares  of  Common  Stock  held by the
Participant  having an aggregate Fair Market Value, as determined on the date of
delivery,  equal to the Option  Price.  The Committee may also permit the Option
Price to be paid by any other method permitted by law,  including by delivery to
the  Committee  from the  Participant  of an election  directing  the Company to
withhold the number of shares of Common  Stock from the Common  Stock  otherwise
due upon  exercise of the Option  having an aggregate  Fair Market Value on that
date equal to the Option  Price.  If a  Participant  pays the Option  Price with
shares of Common Stock which were received by the  Participant  upon exercise of
one or more ISOs, and such Common Stock has not been held by the Participant for
at least the greater of:

            (a)   two years from the date the ISOs were granted or

            (b) one year after the transfer of the shares of Common Stock to the
Participant,  the use of the shares shall constitute a disqualifying disposition
and the ISO  underlying  the shares used to pay the Option Price shall no longer
satisfy all of the requirements of Code Section 422.



12.   Vesting

      A Participant may not exercise an Option or surrender  Phantom Stock or an
SAR until it has become vested.  Similarly,  no share of Restricted Stock may be
sold,  transferred,  reassigned,  pledged or otherwise encumbered or disposed of
until it is vested. The portion of an Award of Options,  SARs,  Restricted Stock
and/or  Phantom  Stock that is vested  depends  upon the period that has elapsed
since the Award Date.  The following  schedule  applies to any Award of Options,
SARs,  Restricted  Stock and Phantom  Stock under this Plan unless the Committee
establishes a different vesting schedule on the Award Date:

      Number of Years Since Award Date          Vested Percentage
      Fewer than two........................................    None
      Two but fewer than three .............................     40%
      Three but fewer than four.............................     60%
      Four but fewer than five..............................     80%
      Five or more..........................................    100%

      Notwithstanding anything herein to the contrary,  however, all Awards will
become vested and  exercisable  upon the effective date of a "change in control"
and will remain  exercisable during the thirty (30) days following the effective
date of the change in control.  As used in this  paragraph,  the term "change in
control"  means the change in the legal or  beneficial  ownership  of  fifty-one
percent (51%) of the outstanding  shares of Common Stock of the Company within a
six-month period, other than by death or operation of law, or the sale of ninety
percent (90%) or more of the assets of the Company.

      Regardless  of the period  elapsed  since the Award Date, a  Participant's
Awards become fully vested if his employment with the Company and its parent and
subsidiaries terminates for any of the following reasons:

            (a)   retirement on or after his sixty-fifth (65th) birthday;

            (b)   retirement on or after his fifty-fifth (55th) birthday with
consent of the Company;

            (c)   retirement at any age on account of total and permanent
disability as determined by the Company; or

            (d)   death.

      If a Participant terminates employment with the Company for any reason, he
forfeits  any Awards that are not yet vested.  A transfer  from the Company to a
subsidiary or affiliate,  or vice versa,  is not a termination of employment for
purposes of this Plan.


13.   Adjustments to Reflect Changes in Capital Structure

      If there  is any  change  in the  corporate  structure  or  shares  of the
Company, the Committee may make any adjustments  necessary to prevent accretion,
or to protect against  dilution,  in the number and kind of shares authorized by
the Plan and,  with  respect to  outstanding  Awards,  in the number and kind of
shares covered  thereby and in the applicable  Option Price.  For the purpose of
this  Section 13, a change in the  corporate  structure or shares of the Company
includes,  without  limitation,  any change  resulting from a  recapitalization,
stock  split,  stock  dividend,  consolidation,   rights  offering,  separation,
reorganization,  or  liquidation  and any  transaction in which shares of Common
Stock are changed into or exchanged for a different  number or kind of shares of
stock or other securities of the Company or another corporation.

14.   Nontransferability of Awards

      Awards under the Plan are not transferable,  voluntarily or involuntarily,
other  than  by will  or by the  laws of  descent  and  distribution.  During  a
Participant's lifetime, his Options may be exercised only by him.

15.   Rights as Stockholder

      No Common  Stock may be  delivered  upon the  exercise of any Option until
full  payment  has been  made.  A  Participant  has no  rights  whatsoever  as a
stockholder  with  respect to any shares  covered by an Option until the date of
the issuance of a stock certificate for the shares.
16.   Withholding Tax

      The  Company  shall have the right to withhold in cash or shares of Common
Stock with respect to any payments made to Participants under the Plan any taxes
required by law to be withheld because of such payments.

17.   No Right to Employment

      Participation  in the Plan  will not  give any  Participant  a right to be
retained as an employee  of the  Company or its parent or  subsidiaries,  or any
right or claim to any  benefit  under  the Plan,  unless  the right or claim has
specifically accrued under the Plan.

18.   Amendment of the Plan

      The Board of Directors  may from time to time amend or revise the terms of
this Plan in whole or in part and may, without  limitation,  adopt any amendment
deemed necessary;  provided, however, that (a) no change in any Award previously
granted  to a  Participant  may be made  that  would  impair  the  rights of the
Participant without the Participant's  consent,  (b) no amendment may extend the
period in which a Participant may exercise an ISO beyond the period set forth in
Section  6(a)(ii),  and (c) the Board of Directors may not,  without approval by
the holders of a majority of the shares of the Company present at a stockholders
meeting,  (i) change the aggregate number of shares that may be granted pursuant
to Options and  Restricted  Stock  granted  under the Plan (except in accordance
with the provisions of Section 13), (ii) change the class of eligible  employees
who may receive Awards under the Plan,  (iii) adopt any amendment  affecting the
Option  Price at which  Options  may be  granted,  or (iv)  materially  increase
benefits accruing to Participants under the Plan.


19.   Stockholder Approval

      Operation of the Plan shall be subject to approval by the  stockholders of
the Company within twelve months before or after the date the Plan is adopted by
the Board of Directors in accordance  with Rule 16b-3(b) of the Exchange Act. If
such stockholder  approval is obtained at a duly held stockholders'  meeting, it
may be  obtained  by the  affirmative  vote of the  holders of a majority of the
shares of the Company present at the meeting or represented and entitled to vote
thereon.  If and in the event that the Company registers any class of any equity
security  pursuant  to Section 12 of the  Exchange  Act,  the  approval  of such
stockholders of the Company shall be solicited  substantially in accordance with
Section  14(a) of the  Exchange  Act and the rules and  regulations  promulgated
thereunder,  or (2) solicited  after the Company has furnished in writing to the
holders entitled to vote substantially the same information  concerning the Plan
as that which  would be required by the rules and  regulations  in effect  under
Section 14(e) of the Exchange Act at the time such information is furnished.

      If such stockholder  approval is obtained by written  consent,  it must be
obtained by the unanimous written consent of all stockholders of the Company.

20.   Conditions Upon Issuance of Shares
