respect to any Security Collateral in which any Grantor has any right, title or
interest and that is not an uncertificated security, promptly upon the request
of the Collateral Agent, such Grantor will notify each such issuer of Pledged
Equity that such Pledged Equity is subject to the security interest granted
hereunder.

and cooperate in the execution and delivery of all necessary agreements that the
Agent and/or the Collateral Agent will require to maintain a perfected security
interest in the operating accounts.

such Grantor under the Accounts. In connection with such collections, such
Grantor may take (and, at the Collateral Agent's direction during the
continuation of an Event of Default, may take) such commercially reasonable
action as such Grantor (or the Collateral Agent) may deem necessary or advisable
to enforce collection thereof; provided, however, that the Collateral Agent
shall have the right at any time upon the occurrence and during the continuance
of an Event of Default and upon written notice to such Grantor of its intention
to do so, to notify the obligors under any Accounts, of the assignment of such
Accounts, to the Collateral Agent and to direct such obligors to make payment of
all amounts due or to become due to such Grantor thereunder directly to the
Collateral Agent and, upon such notification and at the expense of such Grantor,
to enforce collection of any such Accounts, to adjust, settle or compromise the
amount or payment thereof, in the same manner and to the same extent as such
Grantor might have done, and to otherwise exercise all rights with respect to
such Accounts, including, without limitation, those set forth set forth in
Section 9-607 of the UCC. After receipt by any Grantor of the notice from the
Collateral Agent referred to in the proviso to the preceding sentence: (i) all
amounts and proceeds (including, without limitation, instruments) received by
such Grantor in respect of the Accounts, of such Grantor shall be received in
trust for the benefit of the Collateral Agent hereunder, shall be segregated
from other funds of such Grantor and shall be either: (A) released to such
Grantor to the extent permitted under the terms of the Credit Agreement so long
as no Event of Default shall have occurred and be continuing, or (B) if any
Event of Default shall have occurred and be continuing, applied as provided in
Section 10.2 of the Credit Agreement, and (ii) such Grantor will not adjust,
settle or compromise the amount or payment of any Account, release wholly or
partly any obligor thereof, or allow any credit or discount thereon. No Grantor
will permit or consent to the subordination of its right to payment under any of
the Accounts to any other indebtedness or obligations of the obligor thereof.

     Section 10. As to Intellectual Property Collateral.

                                      -11-

including, without limitation, in the U.S. Patent and Trademark Office, the U.S.
Copyright Office and any other governmental authority, to: (i) maintain the
validity and enforceability of such Intellectual Property Collateral and
maintain such Intellectual Property Collateral in full force and effect, and
(ii) pursue the registration and maintenance of each patent, trademark (other
than the common law trademark "American Rock Salt"), or copyright registration
or application, now or hereafter included in such Intellectual Property
Collateral of such Grantor, including, without limitation, the payment of
required fees and taxes, the filing of responses to office actions issued by the
U.S. Patent and Trademark Office, the U.S. Copyright Office or other
governmental authorities, the filing of applications for renewal or extension,

applications or extensions, the payment of maintenance fees and the
participation in interference, reexamination, opposition, cancellation,
infringement and misappropriation proceedings, except to the extent failure to
act could not reasonably be expected to cause a Material Adverse Effect.

          (b) Except as could not be reasonably expected to have a Material
Adverse Effect, no Grantor shall do or permit any act or knowingly omit to do
any act whereby any of its Intellectual Property Collateral may lapse or become
invalid or unenforceable or placed in the public domain.

          (c) Except where failure to do so could not reasonably be expected to
cause a Material Adverse Effect, each Grantor shall take all commercially
reasonable steps which it or the Collateral Agent (during the continuation of an
Event of Default) deems reasonable and appropriate under the circumstances to
preserve and protect each item of its Intellectual Property Collateral,
including, without limitation, maintaining the quality of any and all products
or services used or provided in connection with any of the Trademarks,
consistent with the quality of the products and services as of the date hereof,
and taking all steps necessary to ensure that all licensed users of any of the
Trademarks use such consistent standards of quality.

          (d) With respect to its Intellectual Property Collateral, each Grantor
agrees to execute or otherwise authenticate an agreement, in substantially the
form set forth in Exhibit B hereto or otherwise in form and substance
satisfactory to the Collateral Agent (an "Intellectual Property Security
Agreement"), for recording the security interest granted hereunder to the
Collateral Agent in such Intellectual Property Collateral with the U.S. Patent
and Trademark Office, the U.S. Copyright Office and any other governmental
authorities necessary to perfect the security interest hereunder in such
Intellectual Property Collateral.

          (e) Each Grantor agrees that should it obtain an ownership interest in
any item of the type set forth in Section 1(q) that is not on the date hereof a
part of the Intellectual Property Collateral ("After-Acquired Intellectual
Property"): (i) the provisions of this Agreement shall automatically apply
thereto, and (ii) any such After-Acquired Intellectual Property and, in the case
of trademarks, the goodwill symbolized thereby, shall automatically become part
of the Intellectual Property Collateral subject to the terms and conditions of
this

                                      -12-

<PAGE>

Agreement with respect thereto. Each Grantor shall give prompt written notice to
the Collateral Agent identifying the After-Acquired Intellectual Property, and
such Grantor shall, concurrently with the delivery of financial statements under
Section 8.7 of the Credit Agreement, execute and deliver to the Collateral
Agent, or otherwise authenticate, an agreement substantially in the form of
Exhibit C hereto or otherwise in form and substance satisfactory to the
Collateral Agent (an "IP Security Agreement Supplement") covering such
After-Acquired Intellectual Property which IP Security Agreement Supplement
shall be recorded with the U.S. Patent and Trademark Office, the U.S. Copyright
Office and any other governmental authorities necessary to perfect the security
interest hereunder in such After-Acquired Intellectual Property.

     Section 11. Voting Rights; Dividends; Etc.

          (a) So long as no Event of Default shall have occurred and be
continuing:

               (i) Each Grantor shall be entitled to exercise any and all voting
and other consensual rights pertaining to the Security Collateral of such
Grantor or any part thereof for any purpose other than originate Entitlement
Orders with respect to any Securities Account or Commodity Account; provided
however, that such Grantor will not exercise or refrain from exercising any such
right if such action would have a material adverse effect on the value of the
Security Collateral or any part thereof.

               (ii) Each Grantor shall be entitled to receive and retain any and
all dividends, interest and other distributions paid in respect of the Security
Collateral of such Grantor if and to the extent that the payment thereof is not
otherwise prohibited by the terms of the Credit Documents; provided, however,
that any and all:

                    (A) dividends, interest and other distributions paid or
payable other than in cash in respect of, and instruments and other property
received, receivable or otherwise distributed in respect of, or in exchange for,
any Security Collateral,

                    (B) dividends and other distributions paid or payable in
cash in respect of any Security Collateral in connection with a partial or total
liquidation or dissolution or in connection with a reduction of capital, capital
surplus or paid-in-surplus and

                    (C) cash paid, payable or otherwise distributed in respect
of principal of, or in redemption of, or in exchange for, any Security
Collateral

shall be, and shall be forthwith delivered to the Collateral Agent to hold as,
Security Collateral and shall, if received by such Grantor, be received in trust
for the benefit of the Collateral Agent, be segregated from the other property
or funds of such Grantor and be forthwith delivered to the Collateral Agent as
Security Collateral in the same form as so received (with any necessary
endorsement).

               (iii) The Collateral Agent will execute and deliver (or cause to
be executed and delivered) to each Grantor all such proxies and other
instruments as such Grantor

                                      -13-

<PAGE>

may reasonably request for the purpose of enabling such Grantor to exercise the
voting and other rights that it is entitled to exercise pursuant to paragraph
(i) above and to receive the dividends or interest payments that it is
authorized to receive and retain pursuant to paragraph (ii) above.

          (b) Upon the occurrence and during the continuance of an Event of
Default:

               (i) All rights of each Grantor (x) to exercise or refrain from
exercising the voting and other consensual rights that it would otherwise be
entitled to exercise pursuant to Section 11(a)(i) shall, upon notice to such
Grantor by the Collateral Agent, cease and (y) to receive the dividends,
interest and other distributions that it would otherwise be authorized to
receive and retain pursuant to Section 11(a)(ii) shall automatically cease, and
all such rights shall thereupon become vested in the Collateral Agent, which
shall thereupon have the sole right to exercise or refrain from exercising such
voting and other consensual rights and to receive and hold as Security
Collateral such dividends, interest and other distributions.

               (ii) All dividends, interest and other distributions that are
received by any Grantor contrary to the provisions of paragraph (i) of this
Section 11(b) shall be received in trust for the benefit of the Collateral
Agent, shall be segregated from other funds of such Grantor and shall be
forthwith paid over to the Collateral Agent as Security Collateral in the same
form as so received (with any necessary endorsement).

               (iii) The Collateral Agent shall be authorized to exercise
exclusive control over all Deposit Accounts, Securities Accounts and Commodity

     Section 12. Transfers and Other Liens; Additional Shares.

          (a) Each Grantor agrees that it will not: (i) sell, assign or

Collateral, other than sales, assignments and other dispositions of Collateral,
and options relating to Collateral, permitted under the terms of the Credit
Agreement, or (ii) create or suffer to exist any Lien upon or with respect to
any of the Collateral of such Grantor except for the pledge, assignment and
security interest created under this Agreement and Liens permitted under the
Credit Agreement.

          (b) Each Grantor agrees that it will: (i) cause each issuer of the
Pledged Equity pledged by such Grantor not to issue any Equity Interests or
other securities in addition to or in substitution for the Pledged Equity issued
by such issuer, except to such Grantor, and (ii) pledge hereunder, immediately
upon its acquisition (directly or indirectly) thereof, any and all additional
Equity Interests or other securities (subject to Section 1(o)(ii) with respect
to Voting Foreign Stock).

     Section 13. Collateral Agent Appointed Attorney-in-Fact. Each Grantor
hereby irrevocably appoints the Collateral Agent such Grantor's
attorney-in-fact, with full authority in the place and stead of such Grantor and
in the name of such Grantor or otherwise, from time to time, upon the occurrence
and during the continuance of an Event of Default, in the Collateral Agent's
discretion, to take any action and to execute any instrument that the Collateral
Agent

                                      -14-

<PAGE>

may deem necessary or advisable to accomplish the purposes of this Agreement,
including, without limitation:

          (a) to obtain and adjust insurance required to be paid to the
Collateral Agent,

          (b) to ask for, demand, collect, sue for, recover, compromise, receive
and give acquittance and receipts for moneys due and to become due under or in
respect of any of the Collateral,

          (c) to receive, indorse and collect any drafts or other instruments,
documents and Chattel Paper, in connection with clause (a) or (b) above, and

          (d) to file any claims or take any action or institute any proceedings
that the Collateral Agent may deem necessary or desirable for the collection of
any of the Collateral or otherwise to enforce compliance with the terms and
conditions of any Assigned Agreement or the rights of the Collateral Agent with
respect to any of the Collateral.

     Section 14. Collateral Agent May Perform. If any Grantor fails to perform
any agreement contained herein, the Collateral Agent may, but without any
obligation to do so and without notice, itself perform, or cause performance of,
such agreement, and the expenses of the Collateral Agent incurred in connection
therewith shall be payable by such Grantor under Section 17.

     Section 15. The Collateral Agent's Duties. The powers conferred on the
Collateral Agent hereunder are solely to protect the Secured Parties' interest
in the Collateral and shall not impose any duty upon it to exercise any such
powers. Except for the safe custody of any Collateral in its possession and the
accounting for moneys actually received by it hereunder, the Collateral Agent
shall have no duty as to any Collateral, as to ascertaining or taking action
with respect to calls, conversions, exchanges, maturities, tenders or other
matters relative to any Collateral, whether or not any Secured Party has or is
deemed to have knowledge of such matters, or as to the taking of any necessary
steps to preserve rights against any parties or any other rights pertaining to
any Collateral. The Collateral Agent shall be deemed to have exercised
reasonable care in the custody and preservation of any Collateral in its
possession if such Collateral is accorded treatment substantially equal to that
which it accords its own property.

     Section 16. Remedies. If any Event of Default shall have occurred and be
continuing:

          (a) The Collateral Agent may exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein or otherwise available
to it, all the rights and remedies of a secured party upon default under the UCC
(whether or not the UCC applies to the affected Collateral) and also may: (i)
require each Grantor to, and each Grantor hereby agrees that it will at its
expense and upon request of the Collateral Agent forthwith, assemble all or part
of the Collateral as directed by the Collateral Agent and make it available to
the Collateral Agent at a place and time to be designated by the Collateral
Agent that is reasonably convenient to both parties; (ii) without notice except
as specified below, sell the Collateral or any part thereof in one

                                      -15-

<PAGE>

or more parcels at public or private sale, at any of the Collateral Agent's
offices or elsewhere, for cash, on credit or for future delivery, and upon such
other terms as the Collateral Agent may deem commercially reasonable; (iii)
occupy any premises owned or to the extent lawful and permitted leased by any of
the Grantors where the Collateral or any part thereof is assembled or located
for a reasonable period in order to effectuate its rights and remedies hereunder
or under law, without obligation to such Grantor in respect of such occupation;
and (iv) exercise any and all rights and remedies of any of the Grantors under
or in connection with the Collateral, or otherwise in respect of the Collateral,
including, without limitation: (A) any and all rights of such Grantor to demand
or otherwise require payment of any amount under, or performance of any
provision of, the Assigned Agreements, the Accounts and the other Collateral,
(B) withdraw, or cause or direct the withdrawal, of all funds with respect to
the Deposit Accounts, and (C) exercise all other rights and remedies with
respect to the Assigned Agreements, the Accounts and the other Collateral,
including, without limitation, those set forth in Section 9-607 of the UCC. Each
Grantor agrees that, to the extent notice of sale shall be required by law, at
least ten (10) days notice to such Grantor of the time and place of any public
sale or the time after which any private sale is to be made shall constitute
reasonable notification. The Collateral Agent shall not be obligated to make any
sale of Collateral regardless of notice of sale having been given. The
Collateral Agent may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned.

          (b) All payments received by any Grantor under or in connection with
any Assigned Agreement or otherwise in respect of the Collateral shall be
received in trust for the benefit of the Collateral Agent, shall be segregated
from other funds of such Grantor and shall be forthwith paid over to the
Collateral Agent in the same form as so received (with any necessary
endorsement).

          (c) The Collateral Agent may, without notice to any Grantor except as
required by law and at any time or from time to time, charge, set-off and
otherwise apply all or any part of the Credit Obligations against any funds held
with respect to any Deposit Account.

          (d) If the Collateral Agent shall determine to exercise its right to
sell all or any of the Security Collateral of any Grantor pursuant to this
Section 16, each Grantor agrees that, upon request of the Collateral Agent, such
Grantor will, at its own expense, do or cause to be done all such other acts and
things as may be necessary to make such sale of such Security Collateral or any
part thereof valid and binding and in compliance with applicable law.

          (e) The Collateral Agent is authorized, in connection with any sale of
the Security Collateral pursuant to this Section 16, to deliver or otherwise
disclose to any prospective purchaser of the Security Collateral: (i) any
registration statement or prospectus, and all supplements and amendments
thereto; (ii) any information and projections; and (iii) any other information
in its possession relating to such Security Collateral.

          (f) Each Grantor acknowledges the impossibility of ascertaining the
amount of damages that would be suffered by the Secured Parties by reason of the
failure by such

                                      -16-

<PAGE>

Grantor to perform any of the covenants contained in subsection (d) above and,
consequently, agrees that, if such Grantor shall fail to perform any of such
covenants, it will pay, as liquidated damages and not as a penalty, an amount
equal to the value of the Security Collateral on the date the Collateral Agent
shall demand compliance with subsection (d) above, and such liquidated damages
shall be applied to reduce the amounts owed by Grantor and which are secured
hereunder.

     Section 17. Indemnity and Expenses.

          (a) Each Grantor agrees to indemnify, defend and save and hold
harmless each Secured Party and each of their Affiliates and their respective
officers, directors, employees, agents and advisors (each, an "Indemnified
Party") from and against, and shall pay on demand, any and all claims, damages,
losses, liabilities and expenses (including, without limitation, reasonable fees
and expenses of counsel) that may be incurred by or asserted or awarded against
any Indemnified Party, in each case arising out of or in connection with or
resulting from this Agreement (including, without limitation, enforcement of
this Agreement), except to the extent such claim, damage, loss, liability or
expense is found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted from such Indemnified Party's gross negligence or
willful misconduct or breach of this Agreement by the Secured Party.

          (b) Each Grantor will upon demand pay to the Collateral Agent the
amount of any and all reasonable expenses, including, without limitation, the
reasonable fees and expenses of its counsel and of any experts and agents, that
the Collateral Agent may incur in connection with: (i) the administration of
this Agreement, (ii) the custody, preservation, use or operation of, or the sale
of, collection from or other realization upon, any of the Collateral of such
Grantor, (iii) the exercise or enforcement of any of the rights of the
Collateral Agent or the other Secured Parties hereunder, or (iv) the failure by
such Grantor to perform or observe any of the provisions hereof.

     Section 18. Amendments; Waivers; Additional Grantors; Etc.

          (a) No amendment or waiver of any provision of this Agreement, and no
consent to any departure by any Grantor herefrom, shall in any event be
effective unless the same shall be in writing and signed by the Collateral
Agent, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given. No failure on the part of
the Collateral Agent or any other Secured Party to exercise, and no delay in
exercising any right hereunder, shall operate as a waiver thereof; nor shall any
single or partial exercise of any such right preclude any other or further
exercise thereof or the exercise of any other right.

          (b) Upon the execution and delivery, or authentication, by any Person
of a security agreement supplement in substantially the form of Exhibit A hereto
(each a "Security Agreement Supplement"): (i) such Person shall be referred to
as an "Additional Grantor" and shall be and become a Grantor hereunder, and each
reference in this Agreement and the other Credit Documents to "Grantor" shall
also mean and be a reference to such Additional Grantor,

                                      -17-

<PAGE>

and each reference in this Agreement and the other Credit Documents to
"Collateral" shall also mean and be a reference to the Collateral of such
Additional Grantor, and (ii) the supplemental Schedules I through VI attached to
each Security Agreement Supplement shall be incorporated into and become a part
of and supplement Schedules I through VI, respectively, hereto, and the
Collateral Agent may attach such supplemental schedules to such Schedules; and
each reference to such Schedules shall mean and be a reference to such Schedules
as supplemented pursuant to each Security Agreement Supplement.

     Section 19. Notices, Etc. All notices and other communications provided for
hereunder shall be in writing (including telegraphic, telex, facsimile
transmission or cable communication) and mailed, telegraphed, telexed,

Credit Documents (other than sales of Inventory in the ordinary course of
business), the Collateral Agent will, at such Grantor's expense, execute and
deliver to such Grantor such documents as such Grantor shall reasonably request
to evidence the release of such item of Collateral from the assignment and
security interest granted hereby; provided, however, that such Grantor shall
have delivered to the Collateral Agent a written request for release describing

disposition in reasonable detail, including, without limitation, the price
thereof and any expenses in connection therewith, together with a form of

Obligations including without limitation, any contingent obligations,

applicable Grantor. Upon any such termination, the Collateral Agent will, at the
applicable Grantor's expense, execute and deliver to such Grantor such documents
as such Grantor shall reasonably request to evidence such termination.

          (c) Provided: (i) Default or no Event of Default has occurred and is
continuing, (ii) the Revolving Credit Maturity Date has not been extended by
either the Agent (as defined in the Credit Agreement) or the Required Lenders

any intent to extend the Revolving Credit

                                      -19-

<PAGE>

Maturity Date beyond the fifth (5th) anniversary of the Closing Date to be
irrevocable and provided no less than six (6) months prior to the Revolving
Credit Maturity Date, which irrevocable notice shall, among other things, (xx)
commit to the extension of the Revolving Credit Maturity Date for a period of
not less than three (3) years, and (yy) commit to the extension of the Revolving
Credit Commitments on comparable terms to the existing Revolving Credit
Commitments (including an extension fee of fifty (50) basis points)) and (iv)
the Borrower replaces the Total Revolving Credit Commitment with another
revolving credit facility provided by another lender or another group of lenders
as of the Revolving Credit Maturity Date, the Collateral Agent shall release
from its Collateral the Working Capital Assets provided that immediately prior
to the release: (1) the Total Revolving Credit Commitment shall have been
terminated and the Revolving Loans and all accrued interest thereon and related
fees have been aid in full, and (2) all Standby L/Cs and any contingent
obligations related thereto have been terminated. Notwithstanding anything to
the contrary contained herein, if the appropriate irrevocable notice described
in this paragraph is delivered to the Borrower, then the Borrower shall not have
the option to replace the existing Total Revolving Credit Commitment with
another credit facility, and no Collateral (including but not limited to the
Working Capital Assets) shall be released. Furthermore, should the Borrower
elect to prepay in full the Total Revolving Credit Commitment prior to the
Revolving Credit Maturity Date, no Collateral (including but not limited to the
Working Capital Assets) shall be released unless and until the Total Term Loan
Commitment and Total Revolving Credit Commitment are irrevocably paid in full
and terminated, and all Letters of Credit issued pursuant to the terms of the
Credit Agreement and terminated in accordance with the terms of the Credit
Agreement.

     Section 22. Execution in Counterparts. This Agreement may be executed in
any number of counterparts, each of which when so executed shall be deemed to be
an original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of an original executed
counterpart of this Agreement.
