WHEREAS, Section 26 of the Agreement authorizes the Company and the Rights Agent, if the Company so directs, so long as the Rights (each as defined in the Agreement) are then redeemable and subject to the restrictions set forth in Section 26, to amend any provision of the Agreement without the approval of any holders of certificates representing Common Shares or Rights (each as defined in the Agreement); and

WHEREAS, the Board has approved amendment of the Rights Agreement, and the execution and delivery of this Amendment, and all acts necessary to make this Amendment a valid agreement, enforceable according to its terms have been performed;

NOW, THEREFORE, in consideration of the foregoing recitals, the parties hereby agree and the Agreement is hereby amended as follows:

1.	Section 1.3 is amended to read as follows:

1.3. A Person shall be deemed the “Beneficial Owner” of and shall be deemed to “beneficially own” any securities:

(i) which such Person or any of such Person’s Affiliates or Associates beneficially owns, directly or indirectly (as determined pursuant to Rule 13d-3 of the General Rules and Regulations under the Exchange Act as in effect on the date of this Agreement);

(ii) which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has (A) the right to acquire (whether such right is exercisable immediately, or only after the passage of time, compliance with regulatory requirements, fulfillment of a condition or otherwise) pursuant to any agreement, arrangement or understanding, whether or not in writing (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public offering of securities), or upon the exercise of conversion rights, exchange rights, rights, warrants or options, or otherwise; provided, however, that a Person shall not be deemed the Beneficial Owner of, or to beneficially own, (w) securities tendered pursuant to a tender or exchange offer made by or on behalf of such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange, (x) securities which such Person has a right to acquire upon the exercise of Rights at any time prior to the time that any Person becomes an

-1-

Acquiring Person, (y) securities issuable upon the exercise of Rights from and after the time that any Person becomes an Acquiring Person if such Rights were acquired by such Person or any of such Person’s Affiliates or Associates prior to the Distribution Date or pursuant to Section 3.1 or Section 22 (“Original Rights”) or pursuant to Section 11.9 or Section 11.15 with respect to an adjustment to Original Rights or (z) securities which such Person or any of such Person’s Affiliates or Associates may acquire, does or do acquire or may be deemed to acquire or may be deemed to have the right to acquire, pursuant to any merger or other acquisition agreement between the Company and such Person (or one or more of such Person’s Affiliates or Associates) if prior to such Person becoming an Acquiring Person the Board of Directors of the Company has approved such agreement and determined that such Person shall not be or be deemed to be the beneficial owner of such securities within the meaning of this Section 1.3; or (B) the right to vote pursuant to any agreement, arrangement or understanding (whether or not in writing); provided, however, that a Person shall not be deemed the Beneficial Owner of, or to beneficially own, any security under this clause (B) if the agreement, arrangement or understanding to vote such security (1) arises solely from a revocable proxy or consent given to such Person in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the applicable rules and regulations of the Exchange Act and (2) is not also then reportable on Schedule 13D under the Exchange Act (or any comparable or successor report); or

(iii) which are beneficially owned, directly or indirectly, by any other Person (or any Affiliate or Associate thereof) and with respect to which such Person or any of such Person’s Affiliates or Associates has any agreement, arrangement or understanding (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public offering of securities), whether or not in writing, for the purpose of acquiring, holding, voting (except pursuant to a revocable proxy or consent as described in the proviso to Section 1.3(ii)(B)) or disposing of any securities of the Company;

provided, however, that no Person who is an officer, director or employee of an Exempt Person shall be deemed, solely by reason of such Person’s status or authority as such, to be the “Beneficial Owner” of, to have “Beneficial Ownership” of or to “beneficially own” any securities that are “beneficially owned” (as defined in this Section 1.3), including, without limitation, in a fiduciary capacity, by an Exempt Person or by any other such officer, director or employee of an Exempt Person. Any Person who, directly or indirectly, creates or uses a trust, proxy, power of attorney, pooling arrangement or any other contract, arrangement or device (including without limitation any derivative, swap or similar transaction or instrument) with the purpose or effect of divesting such Person of beneficial ownership of a security or preventing the vesting of such beneficial ownership to avoid the status of an Acquiring Person or as part of a plan or scheme to evade the reporting requirements of section 13(d) or (g) of the Exchange Act shall be deemed to be the “Beneficial Owner” of such security.

2.	New Section 1.5 is added and shall read as follows:

"Book Entry" shall mean an uncertificated book entry for the Common Stock.

-2-

Existing Sections 1.5 – 1.13 are renumbered 1.6 – 1.14 to reflect this addition.

3.	Section 2 is amended to read as follows:

Section 2. Appointment of Rights Agent. The Company hereby appoints the Rights Agent to act as agent for the Company in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Company may from time to time appoint such co-Rights Agents as it may deem necessary or desirable, upon ten (10) days’ prior written notice to the Rights Agent. The Rights Agent shall have no duty to supervise, and shall in no event be liable for, the acts or omissions of any such co-Rights Agent. In the event the Company appoints one or more co-Rights Agents, the respective duties of the Rights Agent and any co-Rights Agent shall be as the Company shall determine. Contemporaneously with such appointment, if any, the Company shall notify the Rights Agent thereof.

4.	Section 3 is amended to reflect electronic issuance of shares and to read as follows:

Section 3. Issuance of Right Certificates.

3.1. Rights Evidenced by Share Certificates. Until the earlier of (i) the close of business on the tenth day after the Shares Acquisition Date (or, if the tenth Business Day after the Shares Acquisition Date occurs before the Record Date, the close of business on the Record Date), or (ii) the close of business on the tenth Business Day after the date of the earlier of the commencement of, or the first public announcement of the intent of any Person (other than an Exempt Person) to commence, a tender or exchange offer the consummation of which would result in any Person (other than an Exempt Person) becoming the Beneficial Owner of Common Shares aggregating 15% or more of the then outstanding Common Shares of the Company (the earlier of (i) and (ii) being herein referred to as the “Distribution Date”), (x) the Rights (unless earlier expired, redeemed or terminated) will be evidenced (subject to the provisions of Section 3.2) by the certificates or Book Entries for the Common Shares registered in the names of the holders thereof (which certificates for Common Shares shall also be deemed to be Right Certificates) and not by separate certificates or Book Entries, and the record holders of the Common Stock represented by such certificates or Book Entries shall be the record holders of Rights represented thereby, and (y) the Rights (and the right to receive certificates therefor) will be transferable only in connection with the transfer of the underlying Common Shares (including a transfer to the Company). The preceding sentence notwithstanding, prior to the occurrence of a Distribution Date specified as a result of an event described in clause (ii) (or such later Distribution Date as the Board of Directors of the Company may select pursuant to this sentence), the Board of Directors may postpone, one or more times, the Distribution Date which would occur as a result of an event described in clause (ii) beyond the date set forth in such clause (ii). Nothing herein shall permit such a postponement of a Distribution Date after a Person becomes an Acquiring Person. As soon as practicable after the Distribution Date, the Company will prepare and execute, the Rights Agent will countersign and the Company (or, if requested, the Rights Agent) will send, by first-class, postage-prepaid mail, to each record holder of Common Shares as of the close of

-3-

business on the Distribution Date (other than any Acquiring Person or any Associate or Affiliate of an Acquiring Person), at the address of such holder shown on the records of the Company, one or more certificates for Rights, in substantially the form of Exhibit B hereto (a “Right Certificate”), evidencing one Right (subject to adjustment as provided herein) for each Common Share so held. As of the Distribution Date, the Rights will be evidenced solely by such Right Certificates.

3.2. Summary of Rights. On the Record Date or as soon as practicable thereafter, the Company will send or cause to be sent a copy of a Summary of Rights to Purchase Preferred Shares, in substantially the form attached hereto as Exhibit C (the “Summary of Rights”), by first-class, postage-prepaid mail, to each record holder of Common Shares as of the close of business on the Record Date at the address of such holder shown on the records of the Company. With respect to certificates or Book Entries for the Common Stock outstanding as of the Record Date, until the Distribution Date, the Rights will be evidenced by such certificates or Book Entries for the Common Stock and the record holders of the Common Stock shall also be the record holders of the associated rights. Until the earlier of the Distribution Date or the Expiration Date, transfer on the Company's direct registration system of any Common Stock represented by a Book Entry or the surrender for transfer of any certificate for Common Stock shall constitute the surrender for transfer of the Rights associated with the Common Stock evidenced thereby, whether or not accompanied by a copy of the Summary of Rights.

3.3. New Certificates After Record Date. Rights shall be issued in respect of all shares of Common Stock which are issued (whether originally issued or from the Company's treasury) after the Record Date but prior to the earlier of the Distribution Date or the Expiration Date, and, in certain circumstances provided in Section 22 of this Agreement, after the Distribution Date. Rights issued prior to the Distribution Date will be evidenced by certificates or Book Entries for the Common Stock. Certificates for Common Shares and confirmations evidencing Book Entries which become outstanding (whether upon issuance out of authorized but unissued Common Shares, disposition out of treasury or transfer or exchange of outstanding Common Shares) after the Record Date but prior to the earliest of the Distribution Date or the Expiration Date, shall have impressed, printed, stamped, written or otherwise affixed onto them the following legend:

This certificate also evidences and entitles the holder hereof to certain rights as set forth in an Agreement between Compass Minerals International, Inc. (the “Company”) and Computershare Trust Company, N.A., as Rights Agent, as the same may be amended from time to time (the “Agreement”), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of the Company. Under certain circumstances, as set forth in the Agreement, such Rights will be evidenced by separate certificates and will no longer be evidenced by this certificate. The Company will mail to the holder of this certificate a copy of the Agreement without charge after receipt of a written request therefor. As described in the Agreement, Rights which are owned by, transferred to or have been owned by Acquiring Persons or Associates or Affiliates thereof (as defined in the Agreement) shall become null and void and will no longer be transferable.

-4-

With respect to such certificates containing the foregoing legend, until the Distribution Date (or the earlier Expiration Date), the Rights associated with the Common Shares shall be represented by such certificates or Book Entries alone and registered holders of Common Stock shall also be the registerd holders of the associated Rights, and the transfer of shares of Common Stock shall also constitute the transfer of the Rights assocated with such shares of Common Stock. In the event that the Company purchases or acquires any Common Shares after the Record Date but prior to the Distribution Date, any Rights associated with such Common Shares shall be deemed canceled and retired so that the Company shall not be entitled to exercise any Rights associated with the Common Shares which are no longer outstanding. Notwithstanding this Section 3.3, the omission of a legend shall not affect the enforceability of any part of this Agreement or the rights of any holder of the Rights.

5.	Section 7.2 is amended to replace the Purchase Price of $70 with $300, so that such Section reads as follows:

7.2. Purchase. The Purchase Price for each one one-thousandth of a Preferred Share pursuant to the exercise of a Right shall be initially $300, shall be subject to adjustment from time to time as provided in Sections 11, 13 and 26 and shall be payable in lawful money of the United States of America in accordance with Section 7.3.

6.	Section 18 is amended to read as follows:

Section 18. Concerning the Rights Agent. The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder in accordance with a fee schedule to be mutually agreed upon and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, or expense, incurred without gross negligence, bad faith or willful misconduct on the part of the Rights Agent, for anything done or omitted by the Rights Agent in connection with the acceptance and administration of this Agreement, including the costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly.

7.	Section 20.3 is amended to read as follows:

20.3. Standard of Care. The Rights Agent shall be liable hereunder only for its own gross negligence, bad faith or willful misconduct.

8.	The first three sentences of Section 21 are amended to read as follows:

Section 21. Change of Rights Agent. The Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon thirty (30)

-5-

days’ notice in writing mailed to the Company in the event that the Rights Agent or one of its Affiliates is not also the transfer agent for the Company, and to each transfer agent of the Common Shares and/or Preferred Shares, as applicable, by registered or certified mail. In the event the transfer agency relationship in effect between the Company and the Rights Agent terminates, the Rights Agent will be deemed to have resigned automatically and be discharged from its duties under this Agreement as of the effective date of such termination, and the Company shall be responsible for sending any required notice. Following the Distribution Date, the Company shall promptly notify the holders of the Right Certificates by first-class mail of any such resignation.

9.	Section 25 is amended to read as follows:

Section 25. Notices. Notices or demands authorized by this Agreement to be given or made by the Rights Agent or by the holder of any Right Certificate to or on the Company shall be sufficiently given or made if sent by courier delivery (overnight or two-day), or by first-class mail, postage prepaid, addressed (until another address is filed in writing with the Rights Agent) as follows:

10.	Section 27 is amended to read as follows. The Trust Agreement Exhibit D referred to in Section 27.4 below is attached to this Amendment:

Section 27. Exchange.

27.1. Exchange of Common Shares for Rights. The Board of Directors of the Company may, at its option, at any time after the occurrence of a Trigger Event, exchange Common Shares for all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become void pursuant to the provisions of Section 11.1.2) by exchanging at an exchange ratio of that number of Common Shares having an aggregate value equal to the Spread (with such value being based on the current per share market price (as determined pursuant to Section 11.4) on the date of the occurrence of a Trigger Event) per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such amount per Right being hereinafter referred to as the “Exchange Consideration”). Notwithstanding the foregoing, the Board of Directors shall not be empowered to effect such exchange at any time after any Acquiring Person shall have become the Beneficial Owner of 50% or more of the Common Shares then outstanding. From and after the occurrence of an event specified in Section 13.1, any Rights that theretofore have not been exchanged pursuant to this Section 27.1 shall thereafter be exercisable only in accordance with Section 13 and may not be exchanged pursuant to this Section 27.1. The exchange of the Rights by the Board of Directors may be made effective at such time, on such basis and with such conditions as the Board of Directors in its sole discretion may establish.

27.2. Exchange Procedures. Immediately upon the action of the Board of Directors of the Company ordering the exchange for any Rights pursuant to Section 27.1 and without any further action and without any notice, the right to exercise such Rights shall terminate and the only right thereafter of a holder of such Rights shall be to receive the Exchange Consideration. The Company shall promptly give public notice of any such exchange; provided, however, that the failure to give, or any defect in, such notice shall not affect the validity of such exchange. The Company promptly shall mail a notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange shall state the method by which the exchange of the Common Shares for Rights will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than the Rights that have become void pursuant to the provisions of Section 11.1.2) held by each holder of Rights.

27.3. Insufficient Shares. The Company may at its option substitute, and, in the event that there shall not be sufficient Common Shares issued but not outstanding or authorized but unissued to permit an exchange of Rights for Common Shares as contemplated in accordance with this Section 27, the Company shall substitute to the extent of such insufficiency,

-7-

for each Common Share that would otherwise be issuable upon exchange of a Right, a number of Preferred Shares or fraction thereof (or equivalent preferred stock, as such term is defined in Section 11.2) such that the current per share market price (determined pursuant to Section 11.4) of one Preferred Share (or equivalent preferred share) multiplied by such number or fraction is equal to the current per share market price of one Common Share (determined pursuant to Section 11.4) as of the date of such exchange.

27.4. Trust Agreement. Prior to effecting an exchange pursuant to this Section 27, the Board of Directors may direct the Company to enter into a Trust Agreement (the “Trust Agreement”) in substantially the form attached hereto as Exhibit D. If the Board of Directors so directs the Company to enter into the Trust Agreement, at the Effective Time (as defined in the Trust Agreement), the Company shall issue to the trust created by the Trust Agreement (the “Trust”) all of the Common Shares and Preferred Shares, if any, distributable pursuant to the exchange (which, for the avoidance of doubt, shall not include any shares or other securities distributed pursuant to the Initial Distribution (as defined in the Trust Agreement)), along with any dividends or distributions made on such shares or other securities after the Effective Time (as defined in the Trust Agreement), and all stockholders entitled to distribution of such shares or other securities (and any dividends or distributions made thereon after the Effective Time (as defined in the Trust Agreement)) shall be entitled to receive distribution of such shares or other securities (and any dividends or distributions made thereon after the Effective Time (as defined in the Trust Agreement)) from the Trust solely upon compliance with all relevant terms and provisions of the Trust Agreement.

11.	A new Section 35 is added as follows:

Section 25. Force Majeure. Notwithstanding anything to the contrary contained herein, the Rights Agent shall not be liable for any delays or failures in performance resulting from acts beyond its reasonable control including, without limitation, acts of God, terrorist acts, shortage of supply, breakdowns or malfunctions, interruptions or malfunction of computer facilities, or loss of data due to power failures or mechanical difficulties with information storage or retrieval systems, labor difficulties, war, or civil unrest.

12.	Except as expressly amended hereby, the provisions of the Agreement shall remain in full force and effect.

Section 1.3 Appointment of Trustee. The Depositor hereby appoints the Trustee as trustee of the Trust, effective immediately following the distribution of shares of Common Stock issued pursuant to the Exchange to Persons which have provided verification that such Person is not an Acquiring Person or any Associate or Affiliate thereof (the “Initial Distribution”) (the “Effective Time”), to have all the rights, powers and duties set forth herein. The Trustee hereby accepts such appointment and declares that it will hold the Trust Estate (as defined herein) upon the trusts set forth herein and for the use and benefit of the Beneficiaries (as defined herein).

ARTICLE II

BENEFICIARIES

Section 2.1 Beneficiaries. The Exchange Participants who have not received Exchange Shares pursuant to the Initial Distribution shall automatically, and without any action being required of such Persons, be the beneficial owners (each, a “Beneficiary” and collectively, the “Beneficiaries”) of the Trust, each owning the same number of Beneficial Interest Units as shares of Common Stock distributable to such Beneficiary pursuant to the Exchange (together with any dividends and distributions thereon made after the Effective Time). For purposes of this Trust Agreement, “Beneficial Interest Units” shall mean equal units of the undivided beneficial interest (as provided in this Trust Agreement) of the Beneficiaries in the Trust Estate.

Exhibit D

To Rights Agreement

ARTICLE IV

DISTRIBUTIONS OF TRUST ESTATE

Section 4.1 Distributions. Each Beneficial Interest Unit shall entitle the holder thereof to distribution of a like number of shares of Common Stock from the Trust upon the terms and conditions provided herein, plus any dividends or distributions on the underlying shares of Common Stock made after the Effective Time. The Trustee shall distribute shares of Common Stock (plus any dividends or distributions on the underlying shares of Common Stock made after the Effective Time) to a Beneficiary that has complied with Section 4.2 hereof as promptly as practicable following the date on which such Beneficiary has provided the Trustee with the certification required by Section 4.2 hereof. Upon receipt of the certification of a Beneficiary required by Section 4.2 hereof, the Trustee shall (i) notify [__________] (or any successor transfer agent) and the Depositor of the name of such Beneficiary and the number of shares of Common Stock requested by such certifying Beneficiary and (ii) submit a transfer instruction, in the form attached hereto as Exhibit B, to [__________] (or any such successor transfer agent), directing the transfer of the requested number of shares of Common Stock held by the Trust to the certifying Beneficiary.

Upon the distribution of shares of Common Stock (plus any dividends or distributions on the underlying shares of Common Stock made after the Effective Time) to a Beneficiary such Beneficiary’s Beneficial Interest Units shall be automatically terminated and such Beneficiary will cease to be a Beneficiary of the Trust thereupon. In the event that there are insufficient shares of Common Stock or other assets held by the Trust to honor all requests for distribution made in compliance with this Agreement and received by the Trustee, the Trustee shall notify the Depositor of such deficiency, and the Depositor shall use its best efforts to cause to be issued or delivered to the Trust such number of shares and such other assets as shall be necessary to satisfy such deficiency.

Section 4.2 Certification of Beneficiary Status. As a condition to its receipt of any distribution from the Trust, each Beneficiary that is or was a registered owner of Common Stock on the books and records of the Depositor must provide the Trustee with the certification as to Beneficiary status in the form attached hereto as Exhibit C, and each Beneficiary that holds or held its shares beneficially in “street name” must provide the Trustee with the certification as to Beneficiary status in the form attached hereto as Exhibit D. The Trustee shall be fully protected in relying upon such certification and shall have no duty or obligation to verify the status of a Beneficiary or the accuracy of such Beneficiary’s claim to its respective portion of the Trust Estate. Notwithstanding anything to the contrary set forth herein, the Depositor, in its absolute discretion, may exempt any Beneficiary from the requirement to provide any such certification by furnishing to the Trustee written notice specifying the identity of the Beneficiary and the number of Beneficial Interest Units held thereby and representing that the Depositor has declared such Beneficiary to be exempt from such requirement (and the Trustee, in making a distribution to any such Beneficiary, shall be fully protected in relying on the Depositor’s representation that such Beneficiary is exempt from such requirement). Upon receipt of any such notice, the Trustee shall distribute to the relevant Beneficiary that portion of the Trust Estate represented by such Beneficiary’s Beneficial Interest Units and, upon such distribution, such Beneficiary’s Beneficial Interest Units shall be automatically terminated and such Beneficiary shall cease to be a Beneficiary of the Trust.

To Rights Agreement

Section 4.3 Dividends.

4.3.1 Cash Dividends. The Trustee shall receive and hold, subject to the terms of this Agreement, any dividends or distributions declared and paid on the shares included in the Trust Estate (which dividends or distributions shall become part of the Trust Estate) and shall distribute such dividends or distributions to the Beneficiaries in proportion to their respective interests therein in accordance with the terms of this Agreement, such distribution to be equivalent to the dividends or distribution which each respective holder would have otherwise been entitled to receive had such shares not then been included in the Trust Estate at the time of the payment of the dividend or distribution. Payment of any such dividends or distributions shall be made by check or wire transfer as a one-time disbursement at the time of the distribution to such Beneficiary of its respective portion of the Trust Estate.

4.3.2 Trust Account; Money Need Not Be Segregated. (a) If the Trustee shall receive any dividends or distributions on the Trust Estate, the Trustee shall establish and maintain with itself a non-interest bearing trust account (the “Trust Account”), into which it shall deposit, on the same day as received, such dividends or distributions and any future dividends or distributions received by it, for disbursement to the Beneficiaries in accordance with Section 4.3.1 above. No monies received by the Trustee need be segregated in any manner except to the extent required by law, and the Trustee shall not be liable for any interest thereon.

Section 4.4 Stock Dividends. The Trustee shall receive and hold, subject to the terms of this Agreement, any securities of the Company issued in respect of the shares included in the Trust Estate by reason of any capital reorganization, stock split, combination, stock dividend or other distribution, including through any exchange of rights (which securities shall become part of the Trust Estate), and shall deliver such securities to the Beneficiaries in proportion to their respective interests therein in accordance with the terms of this Agreement.

Section 4.5 Merger, Consolidation and Dissolution. In connection with any merger, consolidation or dissolution involving the Company or any shares of Common Stock of the Company or other voting securities held in the Trust immediately prior to the effective time of such merger, consolidation or dissolution, such shares of Common Stock and other voting securities, if any, shall be converted at the effective time of such merger or consolidation into shares of stock or other equity interests of the surviving or resulting entity of such merger or consolidation on the same terms as are provided for all other shares of Common Stock of the Company or voting securities under the agreement of merger or consolidation, as the case may be, or shall be converted at the effective time of such merger or dissolution into the right to receive the consideration payable in connection with such merger or dissolution on the same terms as are provided for all other shares of Common Stock of the Company or voting securities under the agreement of merger or plan of dissolution, as the case may be, and the Trustee shall hold all shares or other equity interests of the surviving or resulting entity into which the shares of Common Stock or other voting securities were directly converted (which shares or other equity interests shall become part of the Trust Estate), or shall take all actions necessary to receive and hold the consideration payable in connection with any merger or dissolution (which consideration shall become

COMMON STOCK ISSUED IN EXCHANGE

FOR PREVIOUSLY OUTSTANDING RIGHTS

On [__________], each right previously outstanding under Rights Agreement (the “Rights Agreement”) of Compass Minerals International, Inc. (the “Company”) was exchanged (the “Exchange”) at the close of business on that date for one share of the Company’s Common Stock (the “Common Stock”). The Exchange does not apply to rights formerly held by any Acquiring Person (defined below) at the time of the Exchange.

On [__________], a committee of the Company’s Board of Directors determined that [__________] and their Affiliates and Associates, as such terms are defined in the Rights Agreement (collectively, the “[__________] Group”), became “Acquiring Persons” as of [__________]. As a result, rights held by members of the [__________] Group became void on that date and members of the [__________] Group are not eligible to participate in the Exchange. No other person or group has been determined to be an Acquiring Person. In order to receive shares of Common Stock in the Exchange, an eligible stockholder is required to certify that it is not an Acquiring Person.

For the avoidance of doubt, members of the [__________] Group are not Beneficiaries under the Trust Agreement.

To receive shares of Common Stock from the Trustee, an eligible stockholder must certify that it is not an Acquiring Person by completing this certification form in the space provided below.

The Rights Agreement defines an “Affiliate” and “Associate” as having the respective meanings ascribed to them in Rule 12b-2 of the General Rules and Regulations of the Securities Exchange Act of 1934, as in effect on [__________], and to the extent not included within such definitions, any other person whose shares of Common Stock would be deemed constructively owned by such first person, owned by a single “entity” as defined in Section 1 .382-3(a)(1) of applicable income tax regulations under the Internal Revenue Code of 1986, as amended (the “Code”), or otherwise aggregated with shares of Common Stock owned by such first person pursuant to the provisions of the Code, or any successor provision or replacement provisions; provided, however, that a person shall not be deemed to be the Affiliate or Associate of another person solely because either or both persons are or were directors of the Company.
