                                 EXHIBIT 10.25

                                   AGREEMENT

     WHEREAS, AMCOL International Corporation (the "Company") considers it
essential and in the best interests of the Company and its shareholders to
foster the continued employment of its key management personnel;

     WHEREAS, Gary L. Castagna ("Employee") is considered a key management
employee, currently serving as Senior Vice President and Chief Financial Officer
of the Company.

     WHEREAS, the Company desires to assure the future continuity of Employee's
services in the event of any actual or threatened "Change in Control" (as
defined in Section 6 below) of the Company.

     IT IS THEREFORE AGREED AS FOLLOWS:

     1.   Effect of Agreement. This Agreement shall be effective and binding
immediately upon its execution. However, except as specifically provided herein,
this Agreement shall not alter materially Employee's duties and obligations to
the Company and the remuneration and benefits which Employee may reasonably
expect to receive from the Company in the absence of a Change in Control.

     2.   Employment On and After Change in Control. Provided that the employee
is an employee of the Company immediately prior to a Change in Control, the
Company shall employ Employee, and Employee shall accept such employment,
effective upon such Change in Control for a period of thirty-six (36) months
after said Change in Control subject to the terms and conditions stated herein.

     3.   Duties After Change In Control. Employee agrees that during the term
of his employment with the Company after a Change in Control, he shall perform
the duties described in Section 12 below and such other duties for the Company
and its subsidiaries consistent with his experience and training as the Board of
Directors of the Company (the "Board" ) or the Board's representatives shall
determine from time to time, which duties shall be at least substantially equal
in status, dignity and character to his duties at the date hereof. He shall also
have the title of Senior Vice President and Chief Financial Officer of the
Company. Employee further agrees to devote his entire working time and attention
to the business of the Company and its subsidiaries and use his best efforts to
promote such business.

     4.   Compensation Prior to Change in Control. Prior to a Change in Control
the Company agrees to pay Employee compensation for his services in an amount,
and to provide him with life insurance, disability, health and other benefits,
as set by the Company from time to time. For the purpose of this Section,
compensation does not include any bonus or other incentive compensation plan or
stock purchase plan, which may vary from year to year at the discretion of the
Company.

     5.   Termination of Employment Prior to a Change of Control. Employee shall
be entitled to terminate his employment prior to a Change in Control at any time
upon sixty (60) days' prior written

                                      -25-
<PAGE>

notice. The Company, shall be able to terminate Employee's employment at any
time prior to a Change in Control with or without cause upon sixty (60) days'
prior written notice (or the payment of salary in lieu thereof). This Section
shall not be construed to reduce any accrued benefits payable in connection with
any termination of Employee's employment prior to a Change in Control.

     Nothing expressed or implied in this Agreement shall create any right or
duty on the part of the Company or Employee to have Employee remain in the
employment of the Company prior to a Change in Control.

     6.   Termination of Employment On or After Change in Control.

          (a) For purposes of this Agreement the term "Change in Control" means
     the change in the legal or beneficial ownership of fifty-one percent (51%)
     of the shares of the Company's common stock within a six-month period other
     than by death or operation of law, or the sale of ninety percent (90%) or
     more of the Company's assets within a six-month period.

          (b) Employee's employment on and after a Change in Control may be
     terminated with just cause by the Company at any time upon not less than
     ten (10) days' prior written notice. Prior to termination for just cause on
     and after a Change in Control, the Board of Directors shall by majority
     vote have declared that Employee's termination is for just cause
     specifically stating the basis for such determination. In the event such a
     termination occurs, the provisions of Sections 9(a) and 12 below shall
     apply.

          Employee's employment may be terminated on or after a Change in
     Control without just cause pursuant to the constructive termination
     procedures described in the next paragraph or by the Company giving
     Employee not less than thirty (30) days' prior written notice. In the event
     Employee's employment is terminated pursuant to the preceding sentence:

               (i)  the provisions of Section 9(b) below shall apply; and

                    (ii) although Employee's employment term shall be deemed
                    terminated at the end of such notice period (or, in the case
                    of a constructive termination described in the next
                    paragraph, as of the date Employee notifies the Company of
                    such termination), such termination shall in no way affect
                    the term of this Agreement or Employee's duties and
                    obligations under Section 12 below.

          For purposes of this Section 6(b), Employee shall be considered as
     having been terminated by the Company on or after a Change in Control for
     other than just cause provided that he has notified the Company of any of
     the following within ten (10) days of the occurrence thereof:

                    (i) the assignment to Employee of any duties of
                    substantially lesser status, dignity and character than the
                    duties as a Senior Vice

                                      -26-
<PAGE>

               President and Chief Financial Officer of the Company immediately
               prior to the effective date of the Change in Control;

               (ii) a post-Change in Control reduction by the Company in
               Employee's annual base salary or bonus or incentive plan (as in
               effect immediately prior to the effective date of the Change in
               Control);

               (iii) relocation of Employee's office to a location which is more
               than 35 miles from the location in which Employee principally
               works for the Company immediately prior to the effective date of
               the Change in Control; the relocation of the appropriate
               principal executive office of the Company or the Company's
               operating division or subsidiary for which Employee performed the
               majority of his services for the Company during the year prior to
               the effective date of the Change in Control to a location which
               is more than 35 miles from the location of such office
               immediately prior to such date; or his being required by the
               Company in order to perform duties of substantially equal status,
               dignity and character to those duties he performed immediately
               prior to the effective date of the Change in Control to travel on
               the Company's business to a substantially greater extent than is
               consistent with his business travel obligations as of such date;
               or

               (iv) the failure of the Company to continue to provide Employee
               with benefits substantially equivalent to those enjoyed by him
               under any of the Company's life insurance, medical, health and
               accident or disability plans in which he was participating
               immediately prior to the effective date of the Change in Control,
               the taking of any action by the Company which would directly or
               indirectly materially reduce any of such benefits or deprive him
               of any material fringe benefit enjoyed by him immediately prior
               to effective date of the Change in Control, or the failure of the
               Company to provide him with at least the number of paid vacation
               days to which he is entitled on the basis of years of service
               under the Company's normal vacation policy in effect immediately
               prior to the effective date of the Change in Control.

          (c) In the event Employee's employment is terminated on or after a
     Change in Control in any manner not described in Section 6(b) above:

               (i) the provisions of Section 9(b) shall not apply and
               Employee shall instead receive the sums and benefits described in
               Section 9(a); and

                                      -27-
<PAGE>

                    (ii) such termination shall in no way affect the term of
                    this Agreement or Employee's duties or obligations under
                    Section 12 below.

          (d) Any termination of employment of Employee following the
     commencement of any discussions by a shareholder or group of shareholders
     owning legally or beneficially more than 20% of the common stock or an
     officially designated representative of the Board of Directors with a third
     party that results within 180 days in a Change in Control shall (unless
     such termination is for cause or wholly unrelated to such discussions) be
     deemed to be a termination of Employee on and after a Change in Control for
     purposes of this Agreement.

     7.   Notice of Termination. Any termination by the Company or assertion of
termination by Employee shall be communicated by written notice of termination
to the other party at the following address:

          AMCOL International Corporation
          One North Arlington
          1500 West Shure Drive
          Arlington Heights, IL 60004
          Attn: Chief Executive Officer

          Mr. Gary L. Castagna
          AMCOL International Corporation
          One North Arlington
          1500 West Shure Drive
          Arlington Heights, IL 60004

     8.   Disability. If as a result of Employee's incapacity due to physical or
mental illness, he shall have been absent from his duties with the Company for
one hundred eighty (180) days within any twelve-(l2)-consecutive-month period
and within thirty (30) days after written notice of the Company's intention to
terminate his employment is given, Employee shall not have returned to the
performance of his duties with the Company substantially on a full-time basis,
the Company may terminate his employment for disability. This shall not
constitute a termination for the purposes of obtaining benefits pursuant to
Section 9.

     9.   Benefits Upon Termination And Leave Of Employment On or After Change
in the Control.

          (a) If Employee is terminated for just cause on or after a Change in
     Control, he shall only receive the accrued sums and benefits payable to him
     through the date he is terminated; the provisions of Section 9(b) below
     shall not be applicable in such case and Employee shall not receive (or
     shall cease receiving) the payments and benefits described in Section 9(b).

                                      -28-
<PAGE>

          (b) Subject to Employee's compliance with the provisions of Section
     12(a) below, if Employee is terminated during the thirty-six (36) month
     period beginning on and continuing after a Change in Control other than for
     just cause (either at the discretion of the Company's management or
     constructively by the operation of Section 6), he shall receive the
     following payments and benefits in lieu of any other sums or benefits
     otherwise payable to him by the Company:

               (i)   all then accrued pay, benefits, executive compensation and
               fringe benefits, including (but not limited to) pro rata bonus
               and incentive plan earnings;

               (ii)  medical, health and disability benefits which are
               substantially similar to the benefits the Company is providing
               him as of the date of his employment is terminated for a period
               of thirty-six (36) months thereafter; and

               (iii) one dollar less than three times his base period
               compensation.

          The foregoing payments and benefits shall be deemed compensation
     payable for the duties to be performed by Employee pursuant to Section 12
     below. For purposes of this Agreement, (A) Employee's "base period
     compensation" is the average annual "compensation" (as defined below) which
     was includable in his gross income for his base period (i.e., his most
     recent five taxable years ending before the date of the Change in Control);
     and (B) if Employee's base period includes a short taxable year or less
     than all of a taxable year, compensation for such short or incomplete
     taxable year shall be annualized before determining his average annual
     compensation for the base period. (In annualizing compensation, the
     frequency with which payments are expected to be made over an annual period
     shall be taken into account. Thus, any amount of compensation for such a
     short or incomplete taxable year that represents a payment that would not
     be made more than once per year shall not be annualized). The sum payable
     to Employee pursuant to Section 9(b)(iii) shall in any and all cases be
     reduced by any compensation which Employee receives, excluding stock option
     or other stock incentive bonus plan compensation from the date of the
     Change in Control until the termination date. For purposes of Section
     9(iii) and the definitions pertaining to said Section, Employee's
     "compensation" is the compensation which was payable to him by the Company
     or a related entity determined without regard to the following Sections of
     the Internal Revenue Code of 1986, as amended (the "Code"): 125 (cafeteria
     plans), 402(a)(8) (cash or deferred arrangements), 402(h)(1 )(B) (elective
     contributions to simplified employee pensions), and, in the case of
     employer contributions made pursuant to a salary reduction agreement,
     403(b) (tax sheltered annuities).

          Except for the benefits described in Section 9(b)(ii) above, the sums
     due pursuant to this Section 9(b) shall be paid in up to two (2) annual
     installments commencing thirty (30) days after the sums become due. All
     sums due shall be subject to appropriate

                                      -29-
<PAGE>

     withholding and statutory requirements. Employee shall not be required to
     mitigate the amount of any payment provided for in this Section 9(b) by
     seeking other employment or otherwise. Notwithstanding anything stated in
     this Section 9(b) to the contrary, however, the amount of any payment or
     benefit provided for in this Section 9(b) shall be reduced by no more than
     50% by any compensation earned by Employee as a result of employment by
     another employer and the Company shall not be required to provide medical,
     health and/or disability benefits to the extent such benefits would
     duplicate benefits received by Employee in connection with his employment
     with any new employer.

          Notwithstanding anything stated in this Agreement to the contrary, if
     the amounts which are payable and the benefits which are provided to
     Employee under this Agreement, either alone or together with other payments
     which Employee has a right to receive from the Company or any of its
     affiliates, would constitute a "parachute payment" (as defined in Code
     Section 280G), such amounts and benefits shall be reduced, as necessary, to
     the largest amount as will result in no portion of said amounts and
     benefits being either not deductible as a result of Code Section 280G or
     subject to the excise tax imposed by Code Section 4999. The determination
     of any reduction in said amounts and benefits pursuant to the foregoing
     proviso shall be made by the Company in good faith, and such determination
     shall be conclusive and binding on Employee. The amounts provided to
     Employee under this Agreement in connection with a Change in Control, if
     any, shall be deemed allocated to such amounts and/or benefits to be paid
     and/or provided as the Company's Board of Directors in its sole discretion
     shall determine.

     10.  Special Situations. The parties recognize that under certain
circumstances a Change in Control may occur under conditions which make it
inappropriate for Employee to receive the termination benefits or protection set
forth in this Agreement. Therefore, in the event that a Change in Control occurs
for any one of the following reasons, the provisions of Sections 2, 6 and 9
shall not apply:

          (a) the purchase of more than fifty percent (50%) of the stock of the
     Company by an employee stock ownership plan or similar employee benefit
     plan of which Employee is a participant; or

          (b) the purchase of more than fifty percent (50%) of the stock or
     ninety percent (90%) of the assets of the Company by a group of individuals
     or entities including Employee as a member or participant, including but
     not limited to those transactions commonly known as a leveraged or other
     forms of management buy-outs.

     11.  Dispute. Any dispute arising under this Agreement (except Section 12)
shall be promptly submitted to arbitration under the Rules of the American
Arbitration Association. An arbitrator is to be mutually agreed upon by the
parties or upon failure of agreement, designated by the American Arbitration
Association.

     12.  Other Agreements. Except to the extent expressly set forth herein,
this Agreement shall not modify or lessen any benefit or compensation to which
Employee is entitled under any agreement

                                      -30-
<PAGE>

between Employee and the Company or under any plan maintained by the Company in
which he participates or participated. Benefits or compensation shall be payable
thereunder, if at all, according to the terms of the applicable plan(s) or
agreement(s). The terms of this Agreement shall supersede any existing agreement
between Employee and the Company executed prior to the date hereof to the extent
any such Agreement is inconsistent with the terms hereof.

     13.  Successors: Binding Agreement. The Company will require any successor
(whether direct or indirect by purchase, merger, consolidation or otherwise, to
all or substantially all of the business and/or assets of the Company) to
expressly assume and agree to perform this Agreement in the same manner and to
the same extent that the Company would be required to perform it if no such
succession had taken place.

     This Agreement shall inure to the benefit of and be enforceable by
Employee's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees.

     14.  Injunction. The remedy at law for any breach of Section 12 will be
inadequate and the Company, its affiliates and any subsidiaries thereof would
suffer continuing and irreparable injury to their business as a direct result of
any such breach. Accordingly, notwithstanding anything stated herein, if
Employee shall breach or fail to perform any term, condition or duty contained
in Section 12 hereof, then, in such event, the Company shall be entitled to
institute and prosecute proceedings in any court of competent jurisdiction,
either in law or in equity, to obtain the specific performance thereof by
Employee or to seek a temporary restraining order or injunctive relief, without
any' requirement to show actual damages or post bond, to restrict Employee from
violating the provisions of Section 12; however, nothing herein shall be
construed to prevent the Company' seeking such other remedy in the courts, in
case of any breach of this Agreement by Employee, as the Company may elect or
invoke. If court proceedings are instituted by the Company to enforce Section 12
hereof, and the Company is the prevailing party, the Company shall receive, in
addition to any damages awarded, reasonable attorneys' fees, court costs and
ancillary expenses.

     15.  Miscellaneous. This Agreement may not be modified or discharged unless
such waiver, modification or discharge is agreed to in writing and signed by
Employee and such officers of the Company as may be specifically designated by
its Board for that purpose. Except for any failure to give the ten (10) day
notice described in Section 6(b) above, the failure of either party to this
Agreement to object to any breach by the other party or the non-breaching
party's conduct or conduct forbearance shall not constitute a waiver of that
party's rights to enforce this Agreement. No waiver by either party hereto at
any time of any breach by the other party hereto of, or compliance with, any
condition or provision of this Agreement to be performed by such other party
shall be deemed a waiver of any subsequent breach by such other party or any
similar or dissimilar provisions or conditions at the same or any prior or
subsequent time. No agreements or representations, oral or otherwise, express or
implied, with respect to the subject matter hereof have been made by either
party which are not expressly set forth in this Agreement. The validity,
interpretation, construction and performance of this Agreement shall be governed
by the laws of the State of Illinois.

     16.  Non-Competition. Employee remains bound by and subject to any and all
agreements, including without limitation, the non-competition agreement, to
which he is a party, arising out of the sale of the Company's super absorbent
polymer business to BASF. Employee remains bound and

                                      -31-
<PAGE>

subject to all agreements, including non-competes arising out of the sale of the
super-absorbent polymer business to BASF.

     17.  Severability. The parties hereto intend this Agreement to be enforced
to the maximum extent permitted by law. In the event any provision of this
Agreement is deemed to be invalid or unenforceable by any court of competent
jurisdiction, such provisions shall be deemed to be restricted in scope or
otherwise modified to the extent necessary to render the same valid and
enforceable. In the event the provisions of Section 12 cannot be modified
or restricted so as to be valid and enforceable, then the same as well as the
Company's obligation to make any payment or transfer any benefit to Employee in
connection with any termination of Employee's employment shall be deemed excised
from this Agreement, and this Agreement shall be construed and enforced as if
such provisions had originally been incorporated herein as so restricted or
modified or as if such provisions had not originally been contained herein, as
the case may be. The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement which shall remain in full force and effect.

     18.  Survival. The obligations of the parties under this Agreement shall
survive the term of this Agreement.

     19.  Term of Agreement. The term of this Agreement shall commence on April
1, 2001 and end on March 31, 2004; provided, however, that in the event
Employee's employment is terminated while this Agreement is in force, this
Agreement shall terminate when the Company has made all payments to Employee
required by Section 9 hereof and Employee has complied with the duties and
obligations described in Section 12 hereof (all of which duties and obligations
shall specifically survive the termination of the Employee's employment). To the
extent necessary for the Company's enforcement of the provisions of Section 12
above (but only for such purpose), Employee's employment term shall be deemed to
continue through the end of the Agreement term.
