                                       1


                               THE ANNUAL MEETING

General

      This proxy statement is being furnished in connection with the
solicitation of proxies by the Board of Directors of AMCOL for use at the annual
meeting to be held on Thursday, May 13, 2004, at 11:00 AM, local time, at the
Hilton Hotel Northbrook, 2855 North Milwaukee Avenue, Northbrook, Illinois, and
at any adjournment of the annual meeting.

Record Date

      The Board of Directors has fixed the close of business on March 19, 2004,
as the record date for the determination of shareholders entitled to notice of,
and to vote at, the annual meeting or any adjournment. Accordingly, only holders
of record of AMCOL's common stock at the close of business on the record date
will be entitled to vote at the annual meeting, either by proxy or in person. As
of the record date, there were 29,289,008 shares of AMCOL's common stock issued
and outstanding. Each share of AMCOL's common stock entitles the holder to one
vote.

Purpose of the Annual Meeting; Recommendation of the Board of Directors

      At the annual meeting, AMCOL's shareholders will be asked to consider and
vote upon the following matters:

      o     the election of three directors; and
      o     any other business which properly comes before the annual meeting.

      The Board of Directors recommends that you vote "FOR" each of AMCOL's
nominees for director.

Proxies; Vote Required

      Under Delaware law, the election of the three directors must be approved
by the holders of a majority of the shares of AMCOL's common stock represented
by proxy and in person at the annual meeting.

      All properly delivered proxies received by AMCOL prior to the annual
meeting and not revoked will be voted in accordance with the instructions
provided. Unless contrary instructions are marked, proxies will be voted "FOR"
each of AMCOL's nominees for director. The Board of Directors knows of no other
business that will be presented for consideration at the annual meeting. If any
other matter is properly presented, it is the intention of the persons named in
the enclosed proxy to vote in accordance with their best judgment.

      Any shareholder may revoke his or her proxy at any time prior to or at the
annual meeting by doing any of the following:

      o     giving written notice to the Secretary of AMCOL at One North
            Arlington, 1500 West Shure Drive, Suite 500, Arlington Heights,
            Illinois, 60004-7803;
      o     submitting a duly executed proxy bearing a later date;
      o     voting by telephone or the Internet on a later date; or
      o     attending the annual meeting and voting in person.

      Attendance at the annual meeting will not, in itself, constitute
revocation of a proxy.

      In deciding all questions, a holder of AMCOL's common stock is entitled to
one vote, in person or by proxy, for each share held in such holder's name on
the record date. The presence, in person or by proxy, of the holders of a
majority of the outstanding shares of AMCOL's common stock is necessary to
constitute a quorum at


                                       2


the annual meeting. Abstentions and broker non-votes are counted for purposes of
determining the presence or absence of a quorum for the transaction of business
but are not counted for purposes of determining whether a proposal has been
approved. Thus, abstentions and broker non-votes will have the same effect as a
vote against AMCOL's nominees for director.

Proxy Solicitation and Expenses

      The accompanying proxy is being solicited on behalf of the Board of
Directors of AMCOL. All expenses of this solicitation, including the cost of
preparing and mailing this proxy statement, will be paid by AMCOL. Solicitation
of holders of AMCOL's common stock by mail, telephone, facsimile, e-mail or by
personal solicitation may be done by directors, officers and regular employees
of AMCOL, for which they will receive no additional compensation. Brokerage
houses and other nominees, fiduciaries and custodians nominally holding shares
of AMCOL's common stock as of the record date will be requested to forward proxy
soliciting material to the beneficial owners of such shares, and will be
reimbursed by AMCOL for their reasonable out-of-pocket expenses.

      Deferred Compensation Plan.
(2)   The incremental cost of non-cash compensation and other personal benefits
      during any year presented did not exceed the lesser of $50,000 or 10
      percent of the total of annual salary and bonus reported for any of the
      named officers.
(3)   The timing of the vesting of these shares of restricted stock depends on
      whether AMCOL achieves certain target returns on capital in 2003, 2004 and
      2005. With respect to each of 2003, 2004 and 2005, if the target is
      achieved, one-third of the restricted stock award will vest on February
      28, 2006, provided the executive is still employed by AMCOL. If any of
      these targets are not achieved, the unvested shares will vest on May 22,
      2009, provided the officer is still employed by AMCOL. The named officers
      are entitled to receive dividends on these shares of restricted stock.
(4)   Represents the value of 40,000 shares of restricted stock on May 22, 2003,
      the grant date. On December 31, 2003, Mr. Washow held 40,000 restricted
      shares in the aggregate at a value of $812,000.
(5)   Represents the value of 25,000 shares of restricted stock on May 22, 2003,
      the grant date. On December 31, 2003, the named officer held 25,000
      restricted shares in the aggregate at a value of $507,500.
(6)   Represents the value of 18,000 shares of restricted stock on May 22, 2003,
      the grant date. On December 31, 2003, the named officer held 18,000
      restricted shares in the aggregate at a value of $365,400.
(7)   The figures in this column include AMCOL matching contributions under
      AMCOL's Savings Plan and the 401(k) restoration plan whereby the matching
      contributions for salary deferrals in excess of ERISA limits to AMCOL's
      Savings Plan were credited to AMCOL's Deferred Compensation Plan.

(1)   These Non-Qualified Stock Options ("NSOs") were issued pursuant to AMCOL's
      1998 Long-Term Incentive Plan (the "1998 Plan") and may not be exercised
      until they vest. These NSOs vest 33% after one year, 66% after two years,
      and 100% after three years, provided that on death or retirement under
      specified conditions, these NSOs become fully vested. The exercise price
      may not be less than the fair market value of the shares subject to the
      option on the date of grant.
(2)   Based on 310,950 options granted to all employees.
(3)   Fair market value on the date of grant.
(4)   The estimated grant date present value reflected in the above table is
      determined using the Black-Scholes model. The material assumptions and
      adjustments incorporated in the Black-Scholes model in estimating the
      value of the options reflected in the above table include the following:
      an exercise price on the option of $5.67; an option term of 5.1 years; an
      interest rate of 3.00% representing the interest rates on U.S. Treasury
      securities on the date of grant with maturity dates corresponding to the
      vesting of the options; volatility of 54.90%; and dividends at the rate of
      $0.12 per share representing the annualized dividends paid with respect to
      a share of common stock at the date of grant. There have been no
      reductions to reflect the probability of forfeiture due to termination
      prior to vesting, or to reflect the probability of a shortened option term
      due to termination of employment prior to the option expiration date. The
      ultimate values of the options will depend on the future market price of
      AMCOL's stock, which cannot be forecast with reasonable accuracy. The
      actual value, if any, an optionee will realize upon exercise of an option
      will depend on the excess of the market value of AMCOL's common stock over
      the exercise price on the date the option is exercised.

      The above table shows the estimated annual retirement benefits payable on
a straight life annuity basis to participating employees, including officers, in
the earnings and years of service classifications indicated under AMCOL's
retirement plans, which cover substantially all of its domestic employees hired
on or before December 31, 2003 on a non-contributory basis. The estimated
benefits assume (i) that the plans will be continued and (ii) that the employee
will elect to receive his pension at normal retirement age. The table above and
the estimates do not reflect the reduction in an individual's final monthly
compensation due to social security monthly covered compensation. This reduction
is based upon the retirement year for a particular individual.

  ------------------------------------------------------------------------------

      The above table indicates the average earnings for the highest five
consecutive calendar years and the number of years of credited service under the
pension plans as of December 31, 2003 for each of the named officers. Covered
compensation includes a participant's base salary, commissions, bonuses and
salary reductions under AMCOL's Savings Plan and Deferred Compensation Plan. Mr.
Castagna left the employ of AMCOL in 2000 and received his full pension payout
in the form of a lump-sum payment during 2000 in connection with the sale of the
absorbent polymers business, of which he was President. Mr. Castagna was rehired
by AMCOL in 2001.

      Sections 401(a)(17) and 415 of the Internal Revenue Code of 1986, as
amended, limit the annual benefits that may be paid from a tax-qualified
retirement plan. As permitted by the Employee Retirement Income Security Act of
1974, AMCOL has a supplemental plan that authorizes the payment out of general
funds of AMCOL any benefits calculated under provisions of AMCOL's pension plan
that may be above the limits under these sections. The accrued, unfunded
liability of the supplemental plan at September 30, 2003 was $2,417,027.

Employment Agreements

      Each of Messrs. Castagna, Maul, McKendrick, Morrison and Washow are
parties to employment agreements with AMCOL. The initial employment term under
each agreement is three years (expiring in March 2005), with a rolling six-month
extension (unless either party gives notice of expiration six months prior to
the extension). Each agreement provides for an annual salary, a target annual
bonus and a non-competition / non-solicitation covenant effective during
employment and for one year thereafter.


                                       12


      Prior to a Change of Control, if AMCOL terminates an officer without cause
or the officer terminates his employment for Good Reason, the officer is
entitled to receive: (1) his accrued salary and bonus; (2) a pro-rata annualized
bonus; (3) his base salary for 18 months (in the case of Messrs. Castagna, Maul,
McKendrick and Morrison) and 24 months (in the case of Mr. Washow); (4) a lump
sum of any amount then payable to him pursuant to the tax gross-up payment; and
(5) continued employee benefits during a transition period.

      After a Change of Control, if an officer is terminated without cause or
the officer terminates his employment for Good Reason, the officer is entitled
to receive: (1) his accrued salary and bonus; (2) a pro-rata annualized bonus;
(3) a lump sum equal to three times (in the case of Messrs. Castagna and Washow)
or two times (in the case of Messrs. Maul, McKendrick and Morrison) the sum of
his salary and annualized bonus; (4) continued employee benefits for three years
(in the case of Messrs. Castagna and Washow) or two years (in the case of
Messrs. Maul, McKendrick and Morrison) or cash in lieu thereof; and (5) a lump
sum of any amount then payable to him pursuant to the tax gross-up payment. If a
Change in Control occurs, all outstanding stock options, restricted stock and
other equity compensation awards granted to the officer become fully vested and
exercisable.

      If the officer's employment terminates due to his death or disability
prior to a Change of Control or more than seven months after a Change of
Control, the officer or his beneficiaries are entitled to the officer's accrued
salary and bonus and the officer's pro-rata annualized bonus. If the officer's
employment terminates due to his death or disability within seven months after a
Change of Control, the officer or his beneficiaries are entitled to receive the
compensation and benefits described above with respect to termination without
cause after a Change of Control, except that the employee benefits are limited
to welfare benefits.

      If, at any time, AMCOL terminates an officer for cause or the officer
terminates his employment without Good Reason, the officer is entitled to his
accrued salary and bonus, but shall not be entitled to any severance pay.

      A Change of Control is defined as any one or more of the following: (1)
any person (other than certain AMCOL affiliates, an AMCOL subsidiary or an AMCOL
employee benefit plan) acquires 50.1% or more of AMCOL's common stock; (2) the
incumbent directors cease to constitute at least one-half of the AMCOL
directors; (3) all or substantially all of AMCOL's assets are sold (in the case
of Messrs. Maul, McKendrick and Morrison) or 50.1% of AMCOL's assets are sold
(in the case of Messrs. Castagna and Washow); (4) the shareholders approve a
plan of liquidation; and (5) all of the stock or assets of a subsidiary are sold
and the officer serves as president of the subsidiary.

      Good Reason is defined as the occurrence of any one of the following
events: (1) any material breach of the employment agreement by AMCOL which has
not been cured as required; (2) AMCOL's failure to assign the employment
agreement to a successor or the successor's failure to expressly assume and
agree to be bound by the employment agreement; or (3) termination of employment
by the officer for any reason or for no reason during the 30-day period

      During 2003, the Board of Directors held six meetings. Each director
attended at least 75% of the aggregate of the total number of meetings of the
Board of Directors and the total number of meetings held by all committees of
the Board on which such director served. Pursuant to our Corporate Governance
Guidelines, which may be found on our website at www.amcol.com, directors are
expected to resign from the Board effective as of the annual shareholders
meeting following the date on which they reach the age of 70.

Director Independence

      AMCOL's Board of Directors has determined that the following directors are
independent as defined in the applicable standards of the New York Stock
Exchange: Messrs. Brown, Casey, Driscoll, Proops, Stahl and Weaver and Ms.
Weaver. These independent directors constitute a majority of the directors of
AMCOL. The Board has also determined that each member of the Audit Committee,
the Compensation Committee and the Nominating and Governance Committee is
independent as defined in the applicable standards of the New York Stock
Exchange, except Mr. Hughes, who serves on the Nominating and Governance
Committee. Mr. Hughes has notified AMCOL that he does not intend to stand for
reappointment to the Nominating and Governance Committee at the 2004 annual
board meeting. In addition, the Board has determined that each member of the
Audit Committee is independent as defined in the applicable rules and
regulations of the Securities and Exchange Commission.

The Audit Committee

      The Audit Committee is responsible for providing assistance to the Board
of Directors in fulfilling the Board's oversight responsibility by monitoring
the integrity of the financial statements of AMCOL, the independent auditor's
qualifications and independence, AMCOL's compliance with legal and regulatory
requirements pertaining to the financial statements, and the performance of
AMCOL's internal audit function and independent auditors. The Committee is also
responsible for appointing the independent auditors for each fiscal year. Due to
changes in the corporate governance rules and guidelines governing the
responsibilities and obligations of the Audit Committee, the Board has elected
not to submit the selection of the independent auditors to AMCOL's shareholders
for approval.

      The Audit Committee is responsible for reviewing and pre-approving all
audit and non-audit services provided by the independent auditor and shall not
engage the independent auditor to perform non-audit services proscribed by law
or regulation. The Committee may delegate pre-approval authority to a member of
the Audit Committee. The decisions of any Audit Committee member to whom
pre-approval authority is delegated must be


                                       14


presented to the full Audit Committee at its next scheduled meeting. In fiscal
2003, 100% of non-audit services were approved by the Audit Committee.

      The Board of Directors has determined that each member of the Audit
Committee is an "audit committee financial expert" as defined in the
Sarbanes-Oxley Act of 2002 and the applicable rules and regulations of the
Securities and Exchange Commission. The Audit Committee operates pursuant to a
charter adopted by the Board, which may be found on our website at www.amcol.com
and is attached to this Proxy Statement as Appendix 1.

The Compensation Committee

      The Compensation Committee assists the Board of Directors in fulfilling
its responsibilities in connection with the compensation of company directors,
officers and employees. Specifically, the Committee is responsible for annually
reviewing and approving corporate goals and objectives relevant to the
compensation of the Chief Executive Officer, evaluating the Chief Executive
Officer's performance in light of those goals and objectives, and as a committee
determining and approving the Chief Executive Officer's compensation level based
on this evaluation. In determining the long-term incentive component of the
Chief Executive Officer's compensation, the Committee considers, among other
things, AMCOL's performance and relative shareholder return, the value of
similar incentive awards to chief executive officers at comparable companies and
awards given to the Chief Executive Officer in past years. This review and
evaluation may involve consultations from time to time with the other
independent directors.

      The Committee is also responsible for reviewing and making recommendations
to the Board with respect to the compensation of officers other than the Chief
Executive Officer, including the annual base salary level; incentive
compensation plans; equity-based plans and retirement plans; employment
agreements, severance arrangements and change in control agreements/provisions,
in each case, as, when and if appropriate; and any special or supplemental
benefits. In carrying out its responsibilities, the Committee has sole authority
to retain and terminate any compensation consultant to be used to assist the
Committee in fulfilling its responsibilities. The Compensation Committee is also
responsible for making recommendations to the Board regarding director
compensation and succession planning. The Compensation Committee operates
pursuant to a charter adopted by the Board, which may be found on our website at
www.amcol.com.

The Nominating and Governance Committee

      The Nominating and Governance Committee is responsible for identifying,
seeking and recommending to the Board of Directors individuals qualified to
become directors consistent with criteria approved by the Board. In considering
potential candidates for the Board, including with respect to incumbent
directors, the Committee considers the potential candidate's integrity and
business ethics; strength of character, judgment and experience, consistent with
the needs of AMCOL; specific areas of expertise and leadership roles; and the
ability to bring diversity to the Board, including whether the potential
candidate brings complementary skills and viewpoints. The Committee also
considers the ability of the individual to allocate the time necessary to carry
out the tasks of board membership including membership on appropriate
committees.

      The Committee identifies potential nominees by asking current directors
and others to notify the Committee if they become aware of persons, meeting the
criteria described above, who may be available to serve on the Board. The
Committee has sole authority to retain and terminate any search firm to be used
to identify director candidates and has sole authority to approve the search
firm's fees and other retention terms. Historically, AMCOL has not engaged third
parties to assist in identifying and evaluating potential nominees, but would do
so in those situations where particular qualifications are required to fill a
vacancy and the Board's contacts are not sufficient to identify an appropriate
candidate. Pursuant to its charter, the Nominating and Governance Committee's
policy is to not consider nominees recommended by shareholders of AMCOL.

      Other responsibilities of the Committee include developing and
recommending to the Board the Corporate Governance Guidelines applicable to
AMCOL, overseeing the evaluations of the Board and management, recommending to
the Board director nominees for each committee, and recommending to the Board


                                       15


the size of the Board and its committee structure. The Nominating and Governance
Committee operates pursuant to a charter adopted by the Board, which may be
found on our website at www.amcol.com.

      Directors who are also full-time employees of AMCOL are not paid for their
services as directors or for attendance at meetings.

      AMCOL provides excess personal liability insurance coverage for its
non-employee directors. The premium paid per non-employee director for such
insurance was approximately $632 for 2003. As of May 15, 2003, non-employee
directors were able to participate in AMCOL's health insurance plan at the
directors' cost.

      In 2003, each of the non-employee directors was granted 3,000 options, as
noted in the above table, at an exercise price of $5.67 per share, the fair
market value on the date of the grant.

Shareholder Communications with the Board of Directors

      AMCOL's annual meeting of shareholders provides an opportunity each year
for shareholders to ask questions of or otherwise communicate directly with
members of our Board of Directors on appropriate matters. Our directors are
expected to attend shareholders meetings pursuant to our Corporate Governance
Guidelines. All of our directors attended the 2003 annual meeting and we
anticipate that all of our directors will attend the 2004 annual meeting.

      In addition, shareholders may, at any time, communicate in writing with
the Audit Committee, any particular director, or the independent directors as a
group, by sending such written communication to AMCOL International Corporation,
Attention: Audit Committee, Presiding Non-Management Director of the Board of
Directors, or the name of a particular board member, as applicable, One North
Arlington, 1500 West Shure Drive, Suite 500, Arlington Heights, Illinois
60004-7803. Copies of written communications received at such address will be
provided to the named addressee. Shareholders may also reach the Audit Committee
by calling AMCOL's alert line at (877) 862-6265. Shareholders may report their
concerns anonymously or confidentially.

             COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

      AMCOL's mission is to supply high-quality performance products and
innovative technologies for mineral and environmental markets worldwide. To
accomplish this objective, AMCOL has developed comprehensive compensation
strategies that emphasize maximizing shareholder value and growth in sales and
earnings. The compensation program has been designed to reinforce and support
AMCOL's business goals and to help the organization both attract and retain high
quality executive talent.

      The Compensation Committee is responsible for annually reviewing and
approving corporate goals and objectives relevant to the compensation of the
Chief Executive Officer, evaluating the Chief Executive Officer's performance in
light of those goals and objectives, and determining and approving the Chief
Executive Officer's compensation level based on this evaluation. This review and
evaluation may involve consultations from time to time with the other
independent directors.

      The Compensation Committee is also responsible for reviewing and making
recommendations to the Board with respect to the compensation of officers other
than the Chief Executive Officer, including the annual base salary level;
incentive compensation plans; equity-based plans and retirement plans;
employment agreements, severance arrangements and change in control
agreements/provisions, in each case, as, when and if appropriate; and any
special or supplemental benefits.

Compensation Committee Philosophy

      The Compensation Committee is committed to implementing and administering
a compensation program that supports and underscores AMCOL's mission and values.
The policies underlying the Compensation Committee's compensation decisions are
enumerated more fully below:

      Compensation opportunities should strengthen AMCOL's ability to attract,
      retain, and encourage the growth and development of the highest caliber
      executive talent upon whose efforts the success of AMCOL largely depends.

      A substantial portion of pay for senior executives should be comprised of
      at-risk, variable compensation whose payout is dependent on the
      achievement of specific corporate and individual performance objectives.
      In addition, the at-risk components of pay will have a significant
      equity-based element to ensure appropriate linkage between executive
      behavior and shareholder interests.

      The Committee considers stock ownership by management to be an important
      means of linking management's interests with those of shareholders. AMCOL
      maintains stock ownership guidelines for its corporate and subsidiary
      officers. The amount of stock required to be owned increases with the
      level of responsibility of each executive, with the Chief Executive
      Officer expected to own stock with a value at least equal to four times
      base salary. Shares that the executives have the right to acquire through
      the exercise of stock options are not included in the calculation of stock
      ownership for purposes of these guidelines. Executives are expected to
      reach their respective stock ownership goals over a three-year period.

      Base and equity compensation components target pay opportunities at the
      median of compensation paid to executives included in AMCOL's comparative
      compensation peer group, while incentive compensation is a function of
      company performance. AMCOL's comparative compensation group is not the
      same as the companies that make up the peer group in the stock price
      performance graph included in this proxy statement. In order to provide an
      appropriate basis for compensation analysis, a group larger than the stock
      price graph's peer group was used; note, however, that a significant
      number of the peer group companies are included in the comparative
      compensation group.


                                       17


Components of Compensation

      AMCOL's executive compensation program consists of several components,
each of which plays a role in supporting overall business goals and pay
philosophy. In assessing the competitiveness of AMCOL's senior executive
compensation programs, available salary data consisting of peer group and other
general manufacturing companies is used for comparison purposes. Compensation
program design is based in part on the pay data for comparable positions at
these companies as well as AMCOL's financial performance. The executive
compensation program consists of base salary, annual incentives and long-term
incentives.

Base Pay

      The initial base salaries for Mr. Washow, the Chief Executive Officer, and
AMCOL's other executive officers were established in their respective employment
agreements. The Compensation Committee annually reviews each executive's base
salary and may grant increases based upon levels of responsibility, breadth of
knowledge, internal equity issues and market pay practices. Salary increases are
based primarily upon individual performance, which is evaluated based on
individual contributions to AMCOL.

      Pursuant to his employment agreement, Mr. Washow's base salary is
$432,000. In arriving at the increase in Mr. Washow's base salary to $450,000
for 2003, the Compensation Committee considered his individual performance and
his long-term contributions to the financial success of AMCOL. The Committee
also compared Mr. Washow's base salary with the base salaries of chief executive
officers from appropriate salary surveys.

Annual Incentives

      Pursuant to the terms of their respective employment agreements, Mr.
Washow and each of the other executive officers are eligible for an annual cash
bonus based on the achievement of target performance goals established annually
by the Compensation Committee. Upon the achievement of the target performance
goals, each executive shall be paid a bonus at least equal to a predetermined
percentage of his base salary. If Mr. Washow achieves the target performance
goal, he is entitled to a bonus at least equal to 100% of his base salary.

      The target performance goals for the Chief Executive Officer and Chief
Financial Officer are based upon AMCOL's return on capital and earnings per
share. Mr. Washow was paid a bonus of $675,000 for the 2003 fiscal year
financial performance of AMCOL. In the case of the other executives, their
target performance goals are tailored for each business segment with an emphasis
on the return on capital and earnings of the particular business segment to
which the executive devotes the majority of his time.

Long-Term Incentives

      Long-term incentives are provided annually in the form of stock options
and/or restricted stock awards. The long-term incentive program serves to focus
executives on long-term shareholder value creation and foster an ownership
mentality among the executive management team. The Compensation Committee
believes the equity incentive program provides a strong link between management
behavior and shareholder interests. The Compensation Committee believes that the
aggregate annual incentive awards granted to all employees should equal between
one and one and a half percent of AMCOL's outstanding common stock. In keeping
with AMCOL's commitment to provide a total compensation package that focuses on
at-risk pay components, long-term incentives will continue to comprise a
meaningful portion of the value of an executive's total compensation package.

      In 2003, the named officers were granted stock option and restricted stock
awards under AMCOL's 1998 Long-Term Incentive Plan. The stock options granted to
the named officers vest 33% after one year, 66% after two years, and 100% after
three years, provided that on death or retirement under specified conditions,
the stock options become fully vested. The timing of the vesting of the
restricted stock awards granted to the named officers depends on whether AMCOL
achieves certain target returns on capital in 2003, 2004 and 2005. With respect
to each of 2003, 2004 and 2005, if the target is achieved, one-third of the
restricted stock award will vest


                                       18


on February 28, 2006, provided the executive is still employed by AMCOL. If any
of these targets are not achieved, the unvested shares will vest on May 22,
2009, provided the officer is still employed by AMCOL.

      In determining the long-term incentive component of Mr. Washow's
compensation, the Compensation Committee considers, among other things, AMCOL's
performance and relative shareholder return, the value of similar incentive
awards to chief executive officers at comparable companies and awards given to
Mr. Washow in prior years. In 2003, Mr. Washow received an option to purchase
30,000 shares of common stock at an exercise price of $5.67 per share and an
award of 40,000 shares of restricted stock, with a total value of $261,200 as of
May 22, 2003, the grant date.

Limitations on Payments

      Code Section 162(m) denies a deduction to any publicly held corporation
for compensation paid to certain "covered employees" in a taxable year to the
extent that such compensation exceeds $1,000,000. "Covered employees" are a
corporation's chief executive officer on the last day of the taxable year and
any other individuals whose compensation is required to be reported to
shareholders under the Securities Exchange Act of 1934 by reason of being among
the four most highly compensated officers (other than the chief executive
officer) for the taxable year and who are employed on the last day of the
taxable year. Compensation paid under some qualified performance-based
compensation arrangements, which (among other things) provide for compensation
based on pre-established performance goals established by a compensation
committee that is composed solely of two or more "outside directors," is not
considered in determining whether a "covered employee's" compensation exceeds
$1,000,000. To the extent that any bonus payments cause the executive's total
compensation to exceed $1,000,000 in any given year, the excess will be deferred
until a year when such amount can be deducted by AMCOL.

                          REPORT OF THE AUDIT COMMITTEE

      Management is responsible for AMCOL's financial reporting process
including its system of internal control, and for the preparation of
consolidated financial statements in accordance with generally accepted
accounting principles. AMCOL's independent auditors are responsible for auditing
those financial statements. The Audit Committee's responsibility is to monitor
and review these processes. It is not our duty or our responsibility to conduct
auditing or accounting reviews or procedures. Therefore, we have relied, without
independent verification, on management's representation that the financial
statements have been prepared with integrity and objectivity and in conformity
with accounting principles generally accepted in the United States of America
and on the representations of the independent auditors included in their report
on AMCOL's financial statements. Our oversight does not provide us with an
independent basis to determine that management has maintained appropriate
accounting and financial reporting principles or policies, or appropriate
internal controls and procedures designed to assure compliance with accounting
standards and applicable laws and regulations. Furthermore, our considerations
and discussions with management and the independent auditors do not assure that
AMCOL's financial statements are presented in accordance with generally accepted
accounting principles, that the audit of AMCOL's financial statements has been
carried out in accordance with generally accepted auditing standards.

Review with Management

      The Audit Committee has reviewed and discussed AMCOL's audited financial
statements for the year ended December 31, 2003 with management.

Review and Discussions with Independent Auditors

      The Audit Committee has discussed with KPMG LLP, AMCOL's independent
auditors, the matters required to be discussed by Statement on Auditing
Standards No. 61, "Communication with Audit Committees," which include, among
other items, matters related to the conduct of the audit of AMCOL's financial
statements.

      The Audit Committee has also received the written disclosures from KPMG
LLP required by Independence Standards Board Standard No. 1, which relates to
the accountants' independence from AMCOL and its related entities, and has
discussed with KPMG LLP their independence from AMCOL.

Conclusion

      Based on the review and discussions referred to above, the Audit Committee
recommended to AMCOL's Board of Directors that AMCOL's audited financial
statements be included in AMCOL's Annual Report on Form 10-K for the year ended
December 31, 2003 filed with the Securities and Exchange Commission.

      compliance fees of $32,748 and $19,673, tax advice and planning fees of
      $111,426 and $78,745, and tax fees in relation to acquisitions of $1,073
      and $35,834.
(4)   All other fees principally includes preparation of expatriate employee tax
      returns, and pension plan administration.

      The Audit Committee has considered whether the provision of these
non-audit services by KPMG LLP is compatible with maintaining auditor
independence.

      A representative of KPMG LLP will be present at the annual meeting, will
be afforded the opportunity to make a statement, and will be available to
respond to appropriate questions.

                             STOCK PERFORMANCE GRAPH

      The following graph sets forth a five-year comparison of cumulative total
shareholder returns for: (i) AMCOL (which trades on the New York Stock
Exchange); (ii) the S&P SmallCap 600 Index; (iii) a new custom peer group of
publicly traded companies; and (iv) the old custom peer group of publicly traded
companies.

      AMCOL chose to replace the old peer group with the new peer group due to
the acquisition of two of the old peer group companies in 2002 and 2003. Using
the assistance of consultants, AMCOL selected the new peer group, which consists
of companies whose businesses, sales sizes, market capitalization and stock
trading volumes were similar to that of AMCOL. The new peer group consists of
the following companies: Calgon Carbon Corporation, Compass Minerals
International, Inc., Martin Marietta Materials, Inc., Minerals Technologies
Inc., Oil-Dri Corporation of America and RPM International Inc. The old peer
group consists of the following companies: Calgon Carbon Corporation,
Mississippi Chemical Corporation and Oil-Dri Corporation of America.

      All returns were calculated assuming dividend reinvestment on a quarterly
basis. Returns were adjusted for spin-offs and other special dividends for both
AMCOL and the peer group companies. Further, the tax-effectiveness of any
distributions to shareholders was not taken into account. The returns of each
company in the peer group have been weighted according to market capitalization.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      Clarence O. Redman, Secretary and a director, is of counsel to Lord,
Bissell & Brook LLP, the principal law firm engaged by AMCOL.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Under the securities laws of the United States, AMCOL's directors, its
executive officers and any persons holding more than 10% of AMCOL's common stock
are required to report their initial ownership of AMCOL's common stock and any
subsequent changes in that ownership to the Securities and Exchange Commission.
Specific due dates for these reports have been established and AMCOL is required
to disclose in this proxy statement if a director or executive officer filed a
late report. During 2003, Mr. P. Weaver and Mr. Maul each failed to file on a
timely basis a Form 4 reporting one sale transaction. In addition, Mr.
McKendrick failed to file on a timely basis a Form 4 reporting a stock option
exercise and a sale. In making these disclosures, AMCOL has relied solely on
written representations of its directors and executive officers and copies of
the reports filed with the Securities and Exchange Commission.

                              SHAREHOLDER PROPOSALS

      Shareholder proposals intended to be included in AMCOL's proxy statement
and form of proxy relating to, and to be presented at, the annual meeting of
shareholders of AMCOL to be held in 2005 must be received by AMCOL on or before
December 3, 2004.

      If a shareholder intends to present a proposal at the 2005 annual meeting
of shareholders but does not seek inclusion of that proposal in AMCOL's proxy
statement for that meeting, such shareholder must deliver written notice of the
proposal to AMCOL in accordance with the requirements of AMCOL's By-Laws.
Generally, such proposals must be delivered to AMCOL between February 14, 2005
and March 14, 2005. All proposals or notices should be directed to the Secretary
of AMCOL at One North Arlington, 1500 West Shure Drive, Suite 500, Arlington
Heights, Illinois 60004-7803.

                                  OTHER MATTERS

      As of the date of this proxy statement, AMCOL's management knows of no
matter not specifically referred to above as to which any action is expected to
be taken at the annual meeting. It is intended, however, that the persons named
as proxies will vote the proxies regarding such other matters and the
transaction of such other business as may be properly brought before the meeting
in accordance with their best judgment.

                                         By Order of the Board of Directors,

                                         Clarence O. Redman

                                                                      Appendix 1

                         AMCOL INTERNATIONAL CORPORATION
                             AUDIT COMMITTEE CHARTER

ORGANIZATION

      There shall be an Audit Committee of the Board of Directors, consisting of
no less than three members, whose members shall meet the independence and
experience requirements of any applicable laws and regulations. The Board of
Directors shall appoint and replace the members on recommendation of the
Nominating and Governance Committee. Each member will be "financially literate"
(or will become so within a reasonable time after his or her appointment to the
Audit Committee), and at least one member of the Audit Committee shall have
accounting or related financial management expertise as determined by the Board
in its business judgment.

      No Director may serve as a member of the Audit Committee if such Director
serves on the audit committees of more than two other public companies unless
the Board of Directors determines that such simultaneous service would not
impair the ability of such Director to effectively serve on the Audit Committee.

      No member of the Audit Committee may receive any compensation from the
Company other than: (i) director's fees (including an equity based component, if
any), and (ii) a pension or other deferred compensation for prior service that
is not contingent on future service.

STATEMENT OF PURPOSE

      The Audit Committee shall provide assistance to the Board of Directors in
fulfilling the Board's oversight responsibility by monitoring: (1) the integrity
of the financial statements of the Company, (2) the independent auditor's
qualifications and independence, (3) the compliance by the Company with legal
and regulatory requirements pertaining to the financial statements, and (4) the
performance of the Company's internal audit function and independent auditors.

DUTIES AND RESPONSIBILITIES

      The Audit Committee has the authority to engage independent legal,
accounting or other advisors as it deems necessary to carry out its duties. The
Company shall provide funding for any advisor employed by the Committee as well
as for administrative expenses that are necessary or appropriate in carrying out
the Committee's duties.

      The Audit Committee shall make regular reports to the Board. The Committee
shall review and assess the adequacy of this Charter annually and recommend any
proposed changes to the Board for approval. The Committee shall annually review
the Committee's own performance.

      The Audit Committee shall be directly responsible for the appointment,
compensation, retention and oversight of the outside auditors, which outside
auditors shall report directly to the Committee. The Audit Committee may consult
with Management, but shall not delegate these responsibilities.

      The Audit Committee shall prepare an Audit Committee Report required by
the rules of the Securities and Exchange Commission to be included in the
Company's annual proxy statement.

      The Audit Committee shall have direct responsibility to review and approve
waivers of the Company's Code of Business Conduct and Ethics for directors,
officers, and "affiliates" of the Company (as that term is defined in Rule 144
of the Securities Act of 1933).




Meetings

      The Audit Committee shall meet as often as it determines, but not less
frequently than quarterly. The Audit Committee shall meet periodically with
Management, the internal auditors and the independent auditors in separate
executive sessions. The Audit Committee may request any officer or employee of
the Company, or the Company's outside counsel or independent auditor, to attend
a meeting of the Committee, or to meet with any member of or consultants to the
Committee.

      In addition to the foregoing responsibilities, the Audit Committee will:

Financial Statement and Disclosure Matters

      1.    Review and discuss annual audited financial statements and quarterly
            financial statements, prior to filing, with Management and the
            independent auditor, including the Company's disclosures under
            "Management's Discussion and Analysis of Financial Condition and
            Results of Operations." With respect to the annual audited financial
            statements, the Committee shall also recommend whether such audited
            financial statements should be included in the Company's Form 10-K.

      2.    Review with management: (i) major issues regarding accounting
            principles and financial statement presentations, including any
            significant changes in the Company's selection or application of
            accounting principles, (ii) any major issues as to the adequacy of
            the Company's internal controls and any special audit steps which
            should be adopted in light of material control deficiencies, and
            (iii) analyses prepared by Management and/or the independent auditor
            setting forth significant financial reporting issues and judgments
            made in connection with the preparation of the financial statements,
            including analyses of the effects of alternative GAAP methods on the
            Company's financial statements.

      3.    Discuss, generally, the Company's earnings press releases, as well
            as financial information and earnings guidance provided to analysts
            and rating agencies. The Committee need not discuss each earnings
            release in advance of release. The Committee shall discuss the type
            of information to be disclosed and the type of presentation to be
            made in the Company's earnings press releases (determine the
            advisability of the use of "pro forma" or "adjusted" non-GAAP
            information).

      4.    Discuss with the independent auditor the effect of regulatory and
            accounting initiatives, as well as the advisability of the use of
            off-balance sheet structures, on the Company's financial statements.

      5.    Discuss with Management the Company's major financial risk exposures
            and the steps Management has taken to monitor and control such
            exposures, including the Company's risk assessment and risk
            management policies.

      6.    Review with the independent auditor any difficulties encountered in
            the course of the audit work, including any restrictions on the
            scope of activities or on access to requested information, and any
            material disagreements with Management.

      7.    Review disclosure made to the Audit Committee and independent
            auditor by the Company's CEO and CFO during their certification
            process on Form 10-K and Form 10-Q about any significant
            deficiencies in the design or operation of internal controls or
            material weaknesses therein and any fraud involving Management or
            other employees who have a significant role in the Company's
            internal controls.




Oversight of the Company's Relationship with the Independent Auditor

      1.    Evaluate the independent auditor's qualifications, performance and
            independence, including a review of the lead audit partner. In
            making its evaluation, the Audit Committee will take into account
            opinions of Management and the Company's internal auditors (or other
            personnel responsible for the internal audit function). The
            Committee should present its conclusions with respect to the
            independent auditor to the full board.

      2.    Obtain and review a report from the independent auditor at least
            annually describing: the auditing firm's internal quality-control
            procedures; any material issues raised by the most recent internal
            quality-control review or peer review of the auditing firm, or by
            any inquiry or investigation by governmental or professional
            authorities, within the preceding five years, respecting one or more
            independent audits carried out by the auditing firm, and any steps
            taken to deal with any such issues; and all relationships between
            the independent auditor and the Company (to assess the auditor's
            independence).

      3.    Assure that any required rotation of the lead audit partner is
            implemented and consider whether, in order to assure continuing
            auditor independence, it is appropriate to adopt a policy of
            rotating the independent auditing firm itself on a regular basis.
            Conclusions concerning such rotation will be presented to the full
            board.

      4.    Recommend to the Board policies for the Company's hiring of
            employees or former employees of the independent auditor who were
            engaged on the Company's account.

      5.    Pre-approve all audit and non-audit services performed by the
            independent auditors. For purposes of disclosure in the Company's
            annual report and proxy statement, the Committee will communicate
            its pre-approval policies and procedures and any pre-approved
            services to Management.

Oversight of the Company's Internal Audit Function

      1.    Ascertain that the internal audit function is carried out
            effectively.

      2.    Discuss with the independent auditor the internal audit function
            including the responsibilities, budget and staffing of the Company's
            internal audit function.

Compliance Oversight Responsibilities

      1.    Establish procedures for the receipt, retention and treatment of
            complaints received by the Company regarding accounting, internal
            accounting controls or auditing matters, and the confidential,
            anonymous submission by employees of concerns regarding questionable
            accounting or auditing matters.

      2.    Discuss with Management and the independent auditor any
            correspondence with regulators or governmental agencies and any
            published reports which raise material issues regarding the
            Company's financial statements or accounting policies.

      3.    Discuss with the Company's legal counsel any legal matters that may
            have a material impact on the financial statements or the Company's
            compliance policies.




LIMITATION OF AUDIT COMMITTEE'S ROLE

      While the Audit Committee has the responsibilities and powers set forth in
this Charter, it is not the duty of the Audit Committee to plan or conduct
audits or to determine that the Company's financial statements and disclosures
are complete and accurate and are in accordance with generally accepted
accounting principles and applicable rules and regulations. These are the
responsibilities of Management and the independent auditor.
