ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

I.  ANNUAL INCENTIVE PLAN AND BASE SALARIES

         On August 3, 2005, the Compensation Committee (the "Committee") of the
Board of Directors of Compass Minerals International, Inc. (the "Company")
approved the Company's Annual Incentive Plan (the "AIP"). The AIP utilizes
formulas based on an employee's base salary multiplied by a set formula to
determine the total payout under the plan.

A. BASE SALARIES FOR 2005

         On March 15, 2005, the Committee approved the annual base salaries of
the Company's executive officers after a review of performance and competitive
market data. The following table sets forth the annual base salary levels (as
updated) of the Company's Named Executive Officers (as referenced in the
Company's proxy statement, dated June 30, 2005, except John Fallis has replaced
Rodney Underdown as a Named Executive Officer) for 2005, and as approved for use
in this Annual Incentive Plan:



         NAME AND POSITION                                                      BASE SALARY

         Michael E. Ducey                                                       $448,000
         President and Chief Executive Officer of CMI and CMG

         Steven Wolf                                                            $291,847
         Senior Vice President, Strategy and Development of CMI; 
         Senior Vice President, Strategy of CMG

         Keith E. Clark                                                         $233,836
         Vice President and General Manager, General Trade of CMI and CMG

         David J. Goadby(1)                                                     $224,598
         Vice President of CMI and CMG and Managing Director of Salt Union Ltd.

         John Fallis                                                            $240,000
         Vice President and General Manager, Highway Deicing of CMI and CMG



     (1) Goadby's salary (118,964 British Pounds) is reported in US dollars at a
conversion rate of $1.888/British Pound

B. ANNUAL INCENTIVE PLAN FOR 2005

         The AIP was ratified by the Board of Directors on August 4, 2005. The
purpose of the AIP is to incent participants to fully utilize the Company's
resources to maximize cash flow and reduce debt. The Company's Named Executive
Officers and certain other executive officers participate in the AIP. For other
employees, participation is based on the recommendation of the CEO and the
executive officers, subject to approval by the Committee.

         AIP payments are based on performance targets established for the 2005
fiscal year. Participants in the AIP are assigned a Target Percentage. A
participant's Target Award is the participant's base salary multiplied by the
Target Percentage. AIP payments may range from 0 to 200% of a participant's
Target Award.

         The following participants have been given the corresponding Target
Percentages: Ron Bryan, 40%; Keith Clark, 40%; Michael Ducey, 80%; John Fallis,
50%; David Goadby, 40%; Rodney Underdown, 40%; and Steven Wolf, 50%.

         The AIP uses three performance components: corporate, divisional and
personal. AIP calculations are divided by allocating 85% to performance measures
(70% EBITDA, which is further divided into 40% corporate and 30% divisional for
division leaders, and 15% debt) and 15% to personal measures.

         The corporate component is broken into two measures:





          o    Actual Earnings Before Income Tax, Depreciation and Amortization,
               as defined by the AIP ("EBITDA") vs. Company EBITDA budget; and

          o    Actual Debt vs. budget "Target Debt." Debt is measured as the
               debt recorded on the books.

         The Divisional component has one measure:

          o    Actual EBITDA vs. Divisional EBITDA budget.

         The Personal component (15%) has one measure; however, it is a
multiplier based upon overall company performance. The personal component can be
paid even if the company does not meet its objectives.

         The Company has added a "clawback" provision, which allows the Company
to recover previously paid bonuses (or portions thereof) if there is a
restatement of earnings.

II.  DIRECTORS' COMPENSATION

         On August 4, 2005 the board of directors approved annual retainer
compensation for the Lead Director ($15,000) and the chair of the Environmental,
Health and Safety Committee ($5,000).
