                         MANAGEMENT CONSULTING AGREEMENT

                  This MANAGEMENT CONSULTING AGREEMENT ("AGREEMENT") is entered
into as of November 28, 2001 by and between Salt Holdings Corporation, a
Delaware corporation (the "COMPANY"), and Apollo Management V L.P., a Delaware
limited partnership ("APOLLO").

                                    RECITALS

                  WHEREAS, the Company and its subsidiaries desire to avail
themselves of Apollo's expertise and consequently has requested Apollo to make
such expertise available from time to time in rendering certain management
consulting and advisory services related to the business and affairs of the
Company and its respective subsidiaries and affiliates and the review and
analysis of certain financial and other transactions.

                  WHEREAS, Apollo and the Company agree that it is in their
respective best interests to enter into this Agreement whereby, for the
consideration specified herein, Apollo has provided and shall provide such
services as an independent consultant to the Company and its subsidiaries.

                                    AGREEMENT

                  NOW, THEREFORE, in consideration of the foregoing, and the
mutual agreements set forth herein and other good and valuable consideration,
the receipt and adequacy of which is hereby acknowledged, the parties hereto,
intending to be legally bound, hereby agree as follows:

                  Section 1. RETENTION OF APOLLO. The Company hereby retains
Apollo, and Apollo accepts such retention, upon the terms and conditions set
forth in this Agreement.

                  Section 2. TERM. This Agreement shall commence on the date
hereof and, unless otherwise extended pursuant to the final sentence of this
Section 2, shall terminate on the tenth anniversary of the date hereof (the
"TERM"). Upon the fifth anniversary of the date hereof, and at the end of each
year thereafter (each of such fifth anniversary and the end of each year
thereafter being a "YEAR END"), the Term shall automatically be extended for an
additional year unless notice to the contrary is given by either party at least
30, but no more than 60, days prior to such Year End, as applicable. The
provisions of Sections 3(d), 5 and 7 through 13 shall survive the termination of
this Agreement.

                  Section 3. MANAGEMENT CONSULTING SERVICES.

                  (a)   Apollo shall advise the Company and the Company's
subsidiaries concerning such management matters that relate to proposed
financial transactions, acquisitions and other senior management matters related
to the business, administration and policies of the Company and its subsidiaries
and affiliates, in each case as the Company shall reasonably and

specifically request by way of written notice to Apollo, which notice shall
specify the services required of Apollo and shall include all background
material necessary for Apollo to complete such services. Apollo shall devote
such time to any such written request as Apollo shall deem, in its discretion,
necessary. Such consulting services, in Apollo's discretion, shall be rendered
in person or by telephone or other communication. Apollo shall have no
obligation to the Company and its subsidiaries as to the manner and time of
rendering its services hereunder, and the Company and its subsidiaries shall not
have any right to dictate or direct the details of the services rendered
hereunder.

     (b) The Company acknowledges and agrees that Apollo (i) has structured the
transactions contemplated by that certain Agreement and Plan of Merger (the
"MERGER AGREEMENT"), dated as of October 13, 2001, by and among IMC Global,
Inc., a Delaware corporation ("SELLER"), Salt Holdings Corporation, a Delaware
corporation and a wholly owned subsidiary of Seller, on the one hand, and on the
other hand, YBR Holdings LLC, a Delaware limited liability company ("PURCHASER")
and YBR Acquisition Corp., a Delaware corporation and a wholly owned subsidiary
of Purchaser, (ii) has arranged for financing for the Company and (iii) has
provided other services in connection with the transactions contemplated by the
Merger Agreement. Apollo agrees to continue to provide services to the Company
and its subsidiaries in connection with the consummation of the transactions
contemplated by the Merger Agreement.

     (c) Apollo shall perform all services to be provided hereunder as an
independent contractor to the Company (or the Company's subsidiaries) and not as
an employee, agent or representative of the Company. Apollo shall have no
authority to act for or to bind the Company, without its prior written consent.

     (d) This Agreement shall in no way prohibit Apollo or any of its partners
or affiliates or any director, officer, partner or employee of Apollo or any of
its partners or affiliates from engaging in other activities, whether or not
competitive with any business of the Company or any of its respective
subsidiaries or affiliates.

     Section 4. COMPENSATION. As consideration for Apollo's agreement to render
the services set forth in Section 3(a) of this Agreement and as compensation for
any such services rendered by Apollo, the Company agrees to pay, or cause its
subsidiaries to pay, to Apollo an annual fee of $1,000,000, payable in equal
quarterly installments of $250,000 each on the first day of each fiscal quarter
(or, if such date is not a business day, on the next business day thereafter).

     As consideration for services rendered and Apollo's agreement to render
services as set forth in Section 3(b), the Company agrees to pay, or cause its
subsidiaries to pay, to Apollo a fee of $7,000,000, which shall be earned upon
consummation of the transactions contemplated by the Merger Agreement.

     Upon presentation by Apollo to the Company of such documentation as may be
reasonably requested by the Company, the Company shall reimburse, or cause its
subsidiaries to reimburse, Apollo for all out-of-pocket expenses, including,
without limitation, legal fees and expenses, and other disbursements incurred by
Apollo, its affiliates or any of its affiliates' directors, officers, employees
or agents in the performance of Apollo's obligations hereunder,

                                        2
<Page>

whether incurred on, after or prior to the date hereof, including, without
limitation, out-of-pocket expenses incurred in connection with the transactions
contemplated by the Merger Agreement and each of the documents referred to
therein.

     Nothing in this Agreement shall have the effect of prohibiting Apollo or
any of its affiliates from receiving from the Company or any of its subsidiaries
or affiliates any other fees, including any fee payable pursuant to Section 6.

     Section 5. INDEMNIFICATION. The Company agrees that it shall, or it shall
cause its subsidiaries to, indemnify and hold harmless Apollo, its affiliates
and its affiliates' directors, officers, employees and agents (collectively, the
"INDEMNIFIED PERSONS") on demand from and against any and all liabilities,
costs, expenses and disbursements (collectively, "Claims") of any kind with
respect to or arising from this Agreement or the performance by any Indemnified
Person of any services in connection herewith. Notwithstanding the foregoing
provision, the Company shall not be liable for any Claim under this Section 5
arising from the willful misconduct of any Indemnified Person.

     Section 6. OTHER SERVICES. If the Company or any of its subsidiaries shall
determine that it is advisable for the Company or such subsidiaries to hire a
financial advisor, consultant investment banker or any similar agent in
connection with any merger, acquisition, disposition, recapitalization, issuance
of securities, financing or any similar transaction, it shall notify Apollo of
such determination in writing. Promptly thereafter, upon the request of Apollo,
the parties shall negotiate in good faith to agree upon appropriate services,
compensation and indemnification for the Company or such subsidiary to hire
Apollo or its affiliates for such services. The Company and its subsidiaries may
not hire any person, other than Apollo or its affiliates, for any services,
unless all of the following conditions have been satisfied: (a) the parties are
unable to agree after 30 days following receipt by Apollo of such written
notice, (b) such other person has a reputation that is at least equal to the
reputation of Apollo in respect of such services, (c) ten business days shall
have elapsed after the Company or such subsidiary provides a written notice to
Apollo of its intention to hire such other person, which notice shall identify
such other person and shall describe in reasonable detail the nature of the
services to be provided, the compensation to be paid and the indemnification to
be provided (d) the compensation to be paid is not more than Apollo was willing
to accept in the negotiations described above, and (e) the indemnification to be
provided is not more favorable to the Company or the applicable subsidiary than
the indemnification that Apollo was willing to accept in the negotiations
described above. In the absence of an express agreement to the contrary, at the
closing of any merger, acquisition or similar transaction, Apollo shall receive
a fee equal to 1% of the aggregate enterprise value paid or provided by the
Company (including the aggregate value of (x) equity securities, warrants,
rights and options acquired or retained, (y) indebtedness acquired, assumed or
refinanced and (z) any other consideration or compensation paid in connection
with such transaction).

     Section 7. NOTICES. All notices, requests, consents and other
communications hereunder shall be in writing and shall be deemed sufficient if
personally delivered, sent by nationally-recognized overnight courier, by
telecopy, or by registered or certified mail, return receipt requested and

to the benefit of Apollo, the Company, the Company's subsidiaries, the
Indemnified Persons and any successors to or assigns of Apollo and the Company;

counterparts, and each such counterpart shall be deemed to be an original
instrument, but all such counterparts together shall constitute but one
agreement.

notice to the other party, waive any provision of this Agreement. The waiver by
any party of a breach of any provision of this Agreement shall not operate or be
construed as a waiver of any subsequent breach.
