Argus Lease, it is determined that the Argus Lease is to be terminated or that

Administrative Agent will promptly advise the Swingline Lender of any such
notice received from a Borrower. The Swingline Lender shall make each Swingline
Loan available to the relevant Borrower by means of a credit to the general
deposit account of such Borrower with the Swingline Lender (or, in the case of a
Swingline Loan made to finance the reimbursement of an LC Disbursement as
provided in Section 2.06(e), by remittance to the relevant Issuing Bank) by 3:00
p.m., New York City time, on the requested date of such Swingline Loan.

          (c)  The Swingline Lender may by written notice given to the
Administrative Agent not later than 12:00 noon, New York City time, on any
Business Day require the Revolving Lenders to acquire participations on such
Business Day in all or a portion of the Swingline Loans outstanding. Such notice
shall specify the aggregate amount of Swingline Loans in which Revolving Lenders
will participate. Promptly upon receipt of such notice, the Administrative Agent
will give notice thereof to each Revolving Lender, specifying in such notice
such Lender's Applicable Percentage of such Swingline Loan or Loans. Each
Revolving Lender hereby absolutely and unconditionally agrees, upon receipt of
notice as provided above, to pay to the Administrative Agent, for the account of
the Swingline Lender, such Lender's Applicable Percentage of such Swingline Loan
or Loans. Each Revolving Lender acknowledges and agrees that its obligation to
acquire participations in Swingline Loans pursuant to this paragraph is absolute
and unconditional and shall not be affected by any circumstance whatsoever,
including the occurrence and continuance of a Default or reduction or
termination of the Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever. Each Revolving
Lender shall comply with its obligation under this paragraph by wire transfer of
immediately available funds, in the same manner as provided in Section 2.06 with
respect to Loans made by such Lender (and Section 2.06 shall apply, MUTATIS
MUTANDIS, to the payment obligations of the Revolving Lenders), and the
Administrative Agent shall promptly pay to the Swingline Lender the amounts so
received by it from the Revolving

<Page>
                                                                              53

Lenders. The Administrative Agent shall notify the relevant Borrower or
Borrowers of any participations in any Swingline Loans acquired pursuant to this
paragraph, and thereafter payments in respect of such Swingline Loans shall be
made to the Administrative Agent and not to the Swingline Lender. Any amounts
received by the Swingline Lender from a Borrower (or other party on behalf of a
Borrower) in respect of a Swingline Loan of such Borrower after receipt by the
Swingline Lender of the proceeds of a sale of participations therein shall be
promptly remitted to the Administrative Agent; any such amounts received by the
Administrative Agent shall be promptly remitted by the Administrative Agent to
the Revolving Lenders that shall have made their payments pursuant to this
paragraph and to the Swingline Lender, as their interests may appear. The
purchase of participations in a Swingline Loan pursuant to this paragraph shall
not relieve a Borrower of any default in the payment thereof.

          SECTION 2.05.  LETTERS OF CREDIT.  (a)  GENERAL. Subject to the terms
and conditions set forth herein, any Borrower may request the issuance of
Letters of Credit for its own account, in a form reasonably acceptable to the
Administrative Agent and the relevant Issuing Bank, at any time and from time to
time during the Revolving Availability Period and prior to the date that is five
Business Days prior to the Revolving Maturity Date. In the event of any
inconsistency between the terms and conditions of this Agreement and the terms
and conditions of any form of letter of credit application or other agreement
submitted by a Borrower to, or entered into by a Borrower with, an Issuing Bank
relating to any Letter of Credit, the terms and conditions of this Agreement
shall control.

          (b)  NOTICE OF ISSUANCE, AMENDMENT, RENEWAL, EXTENSION; CERTAIN
CONDITIONS. To request the issuance of a Letter of Credit (or the amendment,
renewal or extension of an outstanding Letter of Credit), a Borrower shall hand
deliver or telecopy (or transmit by electronic communication, if arrangements
for doing so have been approved by the relevant Issuing Bank) to the relevant
Issuing Bank and the Administrative Agent (reasonably in advance of the
requested date of issuance, amendment, renewal or extension) a notice requesting
the issuance of a Letter of Credit, or identifying the Letter of Credit to be
amended, renewed or extended, and specifying the date of issuance, amendment,
renewal or extension (which shall be a Business Day), the date on which such
Letter of Credit is to expire (which shall comply with

<Page>
                                                                              54

paragraph (c) of this Section), the amount of such Letter of Credit, the name
and address of the beneficiary thereof and such other information as shall be
necessary to prepare, amend, renew or extend such Letter of Credit. If requested
by such Issuing Bank, such Borrower also shall submit a letter of credit
application on such Issuing Bank's standard form in connection with any request
for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or
extended only if (and upon issuance, amendment, renewal or extension of each
Letter of Credit such Borrower shall be deemed to represent and warrant that),
after giving effect to such issuance, amendment, renewal or extension (i) the LC
Exposure shall not exceed $100,000,000 and (ii) the total Revolving Exposures
shall not exceed the total Revolving Commitments.

          (c)  EXPIRATION DATE. Each Letter of Credit shall expire at or prior
to the close of business on the earlier of (i) the date one year after the date
of the issuance of such Letter of Credit (or, in the case of any renewal or
extension thereof, one year after such renewal or extension) and (ii) the date
that is five Business Days prior to the Revolving Maturity Date.

          (d)  PARTICIPATIONS. By the issuance of a Letter of Credit (or an
amendment to a Letter of Credit increasing the amount thereof) and without any
further action on the part of the relevant Issuing Bank or the Lenders, the
Issuing Bank in respect of such Letter of Credit hereby grants to each Revolving
Lender, and each Revolving Lender hereby acquires from such Issuing Bank, a
participation in such Letter of Credit equal to such Lender's Applicable
Percentage of the aggregate amount available to be drawn under such Letter of
Credit. In consideration and in furtherance of the foregoing, each Revolving
Lender hereby absolutely and unconditionally agrees to pay to the Administrative
Agent, for the account of such Issuing Bank, such Lender's Applicable Percentage
of each LC Disbursement made by such Issuing Bank and not reimbursed by the
relevant Borrower on the date due as provided in paragraph (e) of this Section,
or of any reimbursement payment required to be refunded to such Borrower for any
reason. Each Lender acknowledges and agrees that its obligation to acquire
participations pursuant to this paragraph in respect of Letters of Credit is
absolute and unconditional and shall not be affected by any circumstance
whatsoever, including any amendment, renewal or extension of any Letter of
Credit or the occurrence and continuance of a Default or reduction or
termination of the Commitments, and that

<Page>
                                                                              55

each such payment shall be made without any offset, abatement, withholding or
reduction whatsoever.

          (e)  REIMBURSEMENT. If an Issuing Bank shall make any LC Disbursement
in respect of a Letter of Credit, the relevant Borrower shall reimburse such LC
Disbursement by paying to the Administrative Agent an amount equal to such LC
Disbursement not later than 12:00 noon, New York City time, on the date that
such LC Disbursement is made, if such Borrower shall have received notice of
such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or,
if such notice has not been received by such Borrower prior to such time on such
date, then not later than 12:00 noon, New York City time, on (i) the Business
Day that such Borrower receives such notice, if such notice is received prior to
10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day
immediately following the day that such Borrower receives such notice, if such
notice is not received prior to such time on the day of receipt; PROVIDED that,
if such LC Disbursement is not less than $500,000, such Borrower may, subject to
the conditions to borrowing set forth herein, request in accordance with Section
2.03 or 2.04 that such payment be financed with an ABR Revolving Borrowing or
Swingline Loan in an equivalent amount and, to the extent so financed, such
Borrower's obligation to make such payment shall be discharged and replaced by
the resulting ABR Revolving Borrowing or Swingline Loan. If such Borrower fails
to make such payment when due, the Administrative Agent shall notify each
Revolving Lender of the applicable LC Disbursement, the payment then due from
such Borrower in respect thereof and such Lender's Applicable Percentage
thereof. Promptly following receipt of such notice, each Revolving Lender shall
pay to the Administrative Agent its Applicable Percentage of the payment then
due from such Borrower, in the same manner as provided in Section 2.06 with
respect to Loans made by such Lender (and Section 2.06 shall apply, MUTATIS
MUTANDIS, to the payment obligations of the Revolving Lenders), and the
Administrative Agent shall promptly pay to the relevant Issuing Bank the amounts
so received by it from the Revolving Lenders. Promptly following receipt by the
Administrative Agent of any payment from such Borrower pursuant to this
paragraph, the Administrative Agent shall distribute such payment to such
Issuing Bank or, to the extent that Revolving Lenders have made payments
pursuant to this paragraph to reimburse such Issuing Bank, then to such Lenders
and such Issuing Bank as their interests may appear. Any payment made by a
Revolving Lender pursuant to this

<Page>
                                                                              56

paragraph to reimburse such Issuing Bank for any LC Disbursement (other than the
funding of ABR Revolving Loans or a Swingline Loan as contemplated above) shall
not constitute a Loan and shall not relieve such Borrower of its obligation to
reimburse such LC Disbursement.

          (f)  OBLIGATIONS ABSOLUTE. A Borrower's obligation to reimburse LC
Disbursements as provided in paragraph (e) of this Section shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement under any and all circumstances whatsoever and
irrespective of (i) any lack of validity or enforceability of any Letter of
Credit or this Agreement, or any term or provision therein, (ii) any draft or
other document presented under a Letter of Credit proving to be forged,
fraudulent or invalid in any respect or any statement therein being untrue or
inaccurate in any respect, (iii) payment by an Issuing Bank under a Letter of
Credit against presentation of a draft or other document that does not comply
with the terms of such Letter of Credit, or (iv) any other event or circumstance
whatsoever, whether or not similar to any of the foregoing, that might, but for
the provisions of this Section, constitute a legal or equitable discharge of, or
provide a right of setoff against, such Borrower's obligations hereunder.
Neither the Administrative Agent, the Lenders nor any Issuing Bank, nor any of
their Related Parties, shall have any liability or responsibility by reason of
or in connection with the issuance or transfer of any Letter of Credit or any
payment or failure to make any payment thereunder (irrespective of any of the
circumstances referred to in the preceding sentence), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the
relevant Issuing Bank; PROVIDED that the foregoing shall not be construed to
excuse the relevant Issuing Bank from liability to the relevant Borrower to the
extent of any direct damages (as opposed to consequential damages, claims in
respect of which are hereby waived by such Borrower to the extent permitted by
applicable law) suffered by such Borrower that are caused by such Issuing Bank's
failure to exercise care when determining whether drafts and other documents
presented under a Letter of Credit comply with the terms thereof. The parties
hereto expressly agree that, in the absence of gross negligence

<Page>
                                                                              57

or wilful misconduct on the part of the relevant Issuing Bank, such Issuing Bank
shall be deemed to have exercised care in each such determination. In
furtherance of the foregoing and without limiting the generality thereof, the
parties agree that, with respect to documents presented which appear on their
face to be in substantial compliance with the terms of a Letter of Credit, the
relevant Issuing Bank may, in its sole discretion, either accept and make
payment upon such documents without responsibility for further investigation,
regardless of any notice or information to the contrary, or refuse to accept and
make payment upon such documents if such documents are not in strict compliance
with the terms of such Letter of Credit.

          (g)  DISBURSEMENT PROCEDURES. The relevant Issuing Bank shall,
promptly following its receipt thereof, examine all documents purporting to
represent a demand for payment under a Letter of Credit. Such Issuing Bank shall
promptly notify the Administrative Agent and the relevant Borrower by telephone
(confirmed by telecopy) of such demand for payment and whether such Issuing Bank
has made or will make an LC Disbursement thereunder; PROVIDED that any failure
to give or delay in giving such notice shall not relieve such Borrower of its
obligation to reimburse such Issuing Bank and the Revolving Lenders with respect
to any such LC Disbursement.

          (h)  INTERIM INTEREST. If an Issuing Bank shall make any LC
Disbursement, then, unless the relevant Borrower shall reimburse such LC
Disbursement in full on the date such LC Disbursement is made, the unpaid amount
thereof shall bear interest, for each day from and including the date such LC
Disbursement is made to but excluding the date that such Borrower reimburses
such LC Disbursement, at the rate per annum then applicable to ABR Revolving
Loans; PROVIDED that, if the relevant Borrower fails to reimburse such LC
Disbursement when due pursuant to paragraph (e) of this Section, then Section
2.13(c) shall apply. Interest accrued pursuant to this paragraph shall be for
the account of the relevant Issuing Bank, except that interest accrued on and
after the date of payment by any Revolving Lender pursuant to paragraph (e) of
this Section to reimburse such Issuing Bank shall be for the account of such
Lender to the extent of such payment.

          (i)  REPLACEMENT OF AN ISSUING BANK. An Issuing Bank may be replaced
at any time by written agreement among the Company, the Administrative Agent,
the replaced

<Page>
                                                                              58

Issuing Bank and the successor Issuing Bank (if any, it being understood that a
successor Issuing Bank shall not be required if there is more than one Issuing
Bank at the time). The Administrative Agent shall notify the Lenders of any such
replacement of an Issuing Bank. At the time any such replacement shall become
effective, the Company shall pay all unpaid fees accrued for the account of the
replaced Issuing Bank pursuant to Section 2.12(b). From and after the effective
date of any such replacement, (i) if there is a successor Issuing Bank, the
successor Issuing Bank shall have all the rights and obligations of an Issuing
Bank under this Agreement with respect to Letters of Credit to be issued
thereafter and (ii) references herein to the term "Issuing Bank" shall be deemed
to refer to such successor or to any previous Issuing Bank, or to such successor
and all previous Issuing Banks, as the context shall require. After the
replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain
a party hereto and shall continue to have all the rights and obligations of an
Issuing Bank under this Agreement with respect to Letters of Credit issued by it
prior to such replacement, but shall not be required to issue additional Letters
of Credit.

          (j)  CASH COLLATERALIZATION. If any Event of Default shall occur and
be continuing, on the Business Day that the Company receives notice from the
Administrative Agent or the Required Lenders (or, if the maturity of the Loans
has been accelerated, Revolving Lenders with LC Exposure representing greater
than 50% of the total LC Exposure) demanding the deposit of cash collateral
pursuant to this paragraph, the Borrowers shall deposit in an account with the
Administrative Agent, in the name of the Administrative Agent and for the
benefit of the Lenders, an amount in cash equal to the LC Exposure as of such
date plus any accrued and unpaid interest thereon; PROVIDED that the obligation
to deposit such cash collateral shall become effective immediately, and such
deposit shall become immediately due and payable, without demand or other notice
of any kind, upon the occurrence of any Event of Default with respect to any
Borrower described in clause (h) or (i) of Article VII. Each such deposit
pursuant to this paragraph or Section 2.11(b) shall be held by the
Administrative Agent as collateral for the payment and performance of the
obligations of the Borrowers under this Agreement. The Administrative Agent
shall have exclusive dominion and control, including the exclusive right of
withdrawal, over such account. Other than any interest earned on the investment
of such deposits, which

<Page>
                                                                              59

investments shall be made at the option and sole discretion of the
Administrative Agent and at the Borrowers' risk and expense, such deposits shall
not bear interest. Interest or profits, if any, on such investments shall
accumulate in such account. Moneys in such account shall be applied by the
Administrative Agent to reimburse the Issuing Banks for LC Disbursements for
which they have not been reimbursed and, to the extent not so applied, shall be
held for the satisfaction of the reimbursement obligations of the Borrowers for
the LC Exposure at such time or, if the maturity of the Loans has been
accelerated (but subject to the consent of Revolving Lenders with LC Exposure
representing greater than 50% of the total LC Exposure), be applied to satisfy
other obligations of the Borrowers under this Agreement. If the Borrowers are
required to provide an amount of cash collateral hereunder as a result of the
occurrence of an Event of Default, such amount (to the extent not applied as
aforesaid) shall be returned to the relevant Borrowers within three Business
Days after all Events of Default have been cured or waived. If the Borrowers are
required to provide an amount of cash collateral hereunder pursuant to Section
2.11(b), such amount (to the extent not applied as aforesaid) shall be returned
to the relevant Borrowers as and to the extent that, after giving effect to such
return, the Borrowers would remain in compliance with Section 2.11(b) and no
Default shall have occurred and be continuing.

          SECTION 2.06.  FUNDING OF BORROWINGS.  (a)  Each Lender shall make
each Loan to be made by it hereunder on the proposed date thereof by wire
transfer of immediately available funds by 12:00 noon, New York City time, to
the account of the Administrative Agent most recently designated by it for such
purpose by notice to the Lenders; PROVIDED that Swingline Loans shall be made as
provided in Section 2.04. The Administrative Agent will make such Loans
available to the applicable Borrower by promptly crediting the amounts so
received, in like funds, to an account of such Borrower maintained with the
Administrative Agent in New York City and designated by such Borrower in the
applicable Borrowing Request; PROVIDED that ABR Revolving Loans made to finance
the reimbursement of an LC Disbursement as provided in Section 2.05(e) shall be
remitted by the Administrative Agent to the applicable Issuing Bank.

          (b)  Unless the Administrative Agent shall have received notice from a
Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Administrative Agent such Lender's share of such

<Page>
                                                                              60

Borrowing, the Administrative Agent may assume that such Lender has made such
share available on such date in accordance with paragraph (a) of this Section
and may, in reliance upon such assumption, make available to the applicable
Borrower a corresponding amount. In such event, if a Lender has not in fact made
its share of the applicable Borrowing available to the Administrative Agent,
then the applicable Lender and the applicable Borrower severally agree to pay to
the Administrative Agent forthwith on demand such corresponding amount with
interest thereon, for each day from and including the date such amount is made
available to such Borrower to but excluding the date of payment to the
Administrative Agent, at (i) in the case of such Lender, the greater of the
Federal Funds Effective Rate and a rate determined by the Administrative Agent
in accordance with banking industry rules on interbank compensation or (ii) in
the case of such Borrower, the interest rate applicable to ABR Loans. If such
Lender pays such amount to the Administrative Agent, then such amount shall
constitute such Lender's Loan included in such Borrowing.

          SECTION 2.07.  INTEREST ELECTIONS.  (a)  Each Revolving Borrowing and
B Term Borrowing initially shall be of the Type specified in the applicable
Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an
initial Interest Period as specified in such Borrowing Request. Thereafter, the
applicable Borrower, in the case of a Revolving Borrowing, or the Company, in
the case of a B Term Borrowing, may elect to convert such Borrowing to a
different Type or to continue such Borrowing and, in the case of a Eurodollar
Borrowing, may elect Interest Periods therefor, all as provided in this Section.
Such Borrower may elect different options with respect to different portions of
the affected Borrowing, in which case each such portion shall be allocated
ratably among the Lenders holding the Loans comprising such Borrowing, and the
Loans comprising each such portion shall be considered a separate Borrowing.
This Section shall not apply to Swingline Borrowings, which may not be converted
or continued.

          (b)  To make an election pursuant to this Section, the relevant
Borrower shall notify the Administrative Agent of such election by telephone by
the time that a Borrowing Request would be required under Section 2.03 if such
Borrower were requesting a Revolving Borrowing of the Type resulting from such
election to be made on the effective date of such election. Each such telephonic
Interest Election Request shall be irrevocable and shall be confirmed promptly
by hand delivery or

<Page>
                                                                              61

telecopy to the Administrative Agent of a written Interest Election Request in a
form approved by the Administrative Agent and signed by such Borrower.

          (c)  Each telephonic and written Interest Election Request shall
specify the following information in compliance with Section 2.02:

          (i)  the Borrowing to which such Interest Election Request applies
     and, if different options are being elected with respect to different
     portions thereof, the portions thereof to be allocated to each resulting
     Borrowing (in which case the information to be specified pursuant to
     clauses (iii) and (iv) below shall be specified for each resulting
     Borrowing);

         (ii)  the effective date of the election made pursuant to such Interest
     Election Request, which shall be a Business Day;

        (iii)  whether the resulting Borrowing is to be an ABR Borrowing or a
     Eurodollar Borrowing; and

         (iv)  if the resulting Borrowing is a Eurodollar Borrowing, the
     Interest Period to be applicable thereto after giving effect to such
     election, which shall be a period contemplated by the definition of the
     term "Interest Period".

If any such Interest Election Request requests a Eurodollar Borrowing but does
not specify an Interest Period, then the relevant Borrower shall be deemed to
have selected an Interest Period of one month's duration.

          (d)  Promptly following receipt of an Interest Election Request, the
Administrative Agent shall advise each Lender of the details thereof and of such
Lender's portion of each resulting Borrowing.

          (e)  If the relevant Borrower fails to deliver a timely Interest
Election Request with respect to a Eurodollar Borrowing prior to the end of the
Interest Period applicable thereto, then, unless such Borrowing is repaid as
provided herein, at the end of such Interest Period such Borrowing shall be
converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if
an Event of Default has occurred and is continuing and the Administrative Agent,
at the request of the Required Lenders, so notifies the Company, then, so long
as an Event of Default is continuing (i) no

<Page>
                                                                              62

outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing
and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR
Borrowing at the end of the Interest Period applicable thereto.

          SECTION 2.08.  TERMINATION AND REDUCTION OF COMMITMENTS.  (a)  Unless
previously terminated, the Revolving Commitments shall terminate on the
Revolving Maturity Date.

          (b)  The Company may at any time terminate, or from time to time
reduce, the Revolving Commitments; PROVIDED that (i) each reduction of the
Revolving Commitments shall be in an amount that is an integral multiple of
$1,000,000 and not less than $5,000,000 and (ii) the Company shall not terminate
or reduce the Revolving Commitments if, after giving effect to any concurrent
prepayment of the Revolving Loans in accordance with Section 2.11, the sum of
the Revolving Exposures would exceed the total Revolving Commitments.

          (c)  The Company shall notify the Administrative Agent of any election
to terminate or reduce the Revolving Commitments under paragraph (b) of this
Section at least three Business Days prior to the effective date of such
termination or reduction, specifying such election and the effective date
thereof. Promptly following receipt of any such notice, the Administrative Agent
shall advise the Lenders of the contents thereof. Each notice delivered by the
Company pursuant to this Section shall be irrevocable; PROVIDED that a notice of
termination of the Revolving Commitments delivered by the Company may state that
such notice is conditioned upon the effectiveness of other credit facilities, in
which case such notice may be revoked by the Company (by notice to the
Administrative Agent on or prior to the specified effective date) if such
condition is not satisfied. Any termination or reduction of the Commitments of
any Class shall be permanent. Each reduction of the Revolving Commitments shall
be made ratably among the Revolving Lenders in accordance with their respective
Revolving Commitments.

          (d)  The parties hereto acknowledge that the Term Loan B Commitments
have terminated.

          SECTION 2.09.  REPAYMENT OF LOANS; EVIDENCE OF DEBT.  (a)  Each
Borrower hereby unconditionally promises to pay (i) to the Administrative Agent
for the account of each Lender the then unpaid principal amount of each

<Page>
                                                                              63

Revolving Loan owed by such Borrower to such Lender on the Revolving Maturity
Date, (ii) in the case of the Company, to the Administrative Agent for the
account of each Lender the then unpaid principal amount of each B Term Loan of
such Lender as provided in Section 2.10 and (iii) to the Swingline Lender the
then unpaid principal amount of each Swingline Loan owed by such Borrower on the
earlier of the Revolving Maturity Date and the first date after such Swingline
Loan is made that is the 15th or last day of a calendar month and is at least
two Business Days after such Swingline Loan is made; PROVIDED that on each date
that a Revolving Borrowing is made by a Borrower, such Borrower shall repay all
Swingline Loans of such Borrower that were outstanding on the date such
Borrowing was requested.

          (b)  Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness of each Borrower to such
Lender resulting from each Loan made by such Lender, including the amounts of
principal and interest payable and paid to such Lender from time to time
hereunder.

          (c)  The Administrative Agent shall maintain accounts in which it
shall record (i) the amount of each Loan made hereunder, the Class and Type
thereof, the Borrower in respect thereof and the Interest Period applicable
thereto, (ii) the amount of any principal or interest due and payable or to
become due and payable from each Borrower to each Lender hereunder and (iii) the
amount of any sum received by the Administrative Agent hereunder for the account
of the Lenders and each Lender's share thereof.

          (d)  The entries made in the accounts maintained pursuant to paragraph
(b) or (c) of this Section shall be PRIMA FACIE evidence of the existence and
amounts of the obligations recorded therein; PROVIDED that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligation of each Borrower to repay
its Loans in accordance with the terms of this Agreement.

          (e)  Any Lender may request that Loans of any Class made by it to any
Borrower be evidenced by a promissory note. In such event, the applicable
Borrower shall prepare, execute and deliver to such Lender a promissory note
payable to the order of such Lender (or, if requested by such Lender, to such
Lender and its registered assigns) and in a form approved by the Administrative
Agent. Thereafter, the Loans evidenced by

                                                                              64

such promissory note and interest thereon shall at all times (including after
assignment pursuant to Section 9.04) be represented by one or more promissory
notes in such form payable to the order of the payee named therein (or, if such
promissory note is a registered note, to such payee and its registered assigns).

          SECTION 2.10.  AMORTIZATION OF B TERM LOANS.  (a)  Subject to
adjustment pursuant to paragraph (c) of this Section, the Company shall repay B
Term Borrowings (i) on March 31, June 30, September 30 and December 31 of each
year prior to the Term Loan Maturity Date, commencing on September 30, 2001, in
an aggregate principal amount equal to $725,000, and (ii) on the Term Loan
Maturity Date, in an aggregate principal amount equal to $274,775,000.

          (b)  To the extent not previously paid, all B Term Loans shall be due
and payable on the Term Loan Maturity Date.

          (c)  Any prepayment of a B Term Borrowing shall be applied to reduce
the subsequent scheduled repayments of the B Term Borrowings to be made pursuant
to this Section ratably.

          (d)  Prior to any repayment of any B Term Borrowings hereunder, the
Company shall select the B Term Borrowing or B Term Borrowings to be repaid and
shall notify the Administrative Agent by telephone (confirmed by telecopy) of
such selection not later than 11:00 a.m., New York City time, three Business
Days before the scheduled date of such repayment. Each repayment of a Borrowing
shall be applied ratably to the Loans included in the repaid Borrowing.
Repayments of B Term Borrowings shall be accompanied by accrued interest on the
amount repaid.

          SECTION 2.11.  PREPAYMENT OF LOANS.  (a)  Each Borrower shall have the
right at any time and from time to time to prepay any of its Borrowings in whole
or in part, subject to the requirements of this Section.

          (b)  In the event and on each occasion that the sum of the Revolving
Exposures exceeds the total Revolving Commitments, the Borrowers shall prepay
Revolving Borrowings or Swingline Borrowings (or, if no such Borrowings are
outstanding, deposit cash collateral in an account with the Administrative Agent
pursuant to Section 2.05(j)) in an aggregate amount equal to such excess.

<Page>
                                                                              65

          (c)  In the event and on each occasion that any Net Proceeds are
received by or on behalf of the Company or any Subsidiary in respect of any
Prepayment Event or the Salt Disposition, the Company shall, within three
Business Days after such Net Proceeds are received, prepay Borrowings (or, in
the case of Revolving Borrowings, cause such Borrowings to be prepaid) in an
aggregate amount equal to such Net Proceeds (or, in the case of the Salt
Disposition, as provided in paragraph (f) of this Section) in the manner
specified in paragraphs (d), (e) and (f) of this Section; PROVIDED that, in the
case of any event described in clause (a) of the definition of the term
Prepayment Event, if the Company shall deliver to the Administrative Agent a
certificate signed on behalf of the Company by a Financial Officer to the effect
that the Company and its Subsidiaries intend to apply (or enter into contractual
commitments to apply) the Net Proceeds from such event (or a portion thereof
specified in such certificate), within 270 days after receipt of such Net
Proceeds (and, in the case of any such contractual commitments, to apply such
Net Proceeds within 360 days after receipt of such Net Proceeds), to acquire
real property, equipment or other tangible assets to be used in the business of
the Company and its Subsidiaries, and certifying that no Default has occurred
and is continuing, then no prepayment shall be required pursuant to this
paragraph in respect of the Net Proceeds in respect of such event (or the
portion of such Net Proceeds specified in such certificate, if applicable)
except (i) to the extent of any such Net Proceeds therefrom that have not been
so applied (or so committed to be applied) by the end of such 270-day period, at
which time a prepayment shall be required in an amount equal to such Net
Proceeds that have not been so applied (or so committed to be applied) and (ii)
in the case of any such Net Proceeds therefrom that, as of the end of such
270-day period, have been so committed to be so applied but have not yet been so
applied, to the extent such Net Proceeds have not been so applied within 360
days after receipt of such Net Proceeds, at which time a prepayment shall be
required in an amount equal to such Net Proceeds that have not been so applied.
Notwithstanding the foregoing, if (A) any event occurs that constitutes a
"Prepayment Event" (or would constitute a "Prepayment Event" except by reason of
any of the exclusions set forth in the definition of the term "Prepayment
Event"), (B) the Company or any Loan Party would be required to prepay, redeem
or repurchase (or offer to prepay, redeem or repurchase) any New Senior Notes or
other Material Indebtedness as a result of such event (a "PREPAYMENT
REQUIREMENT") and (C) the Prepayment

<Page>
                                                                              66

Requirement would be avoided or reduced if Borrowings were prepaid, then, as and
to the extent necessary to avoid or reduce the Prepayment Requirement, the
Company shall cause Borrowings to be prepaid immediately prior to the expiry of
any period that, if Borrowings are prepaid during such period, the Prepayment
Requirement would be so avoided or reduced.

          (d)  Prior to any optional or mandatory prepayment of Borrowings
hereunder, the relevant Borrower shall select the Borrowing or Borrowings to be
prepaid and shall specify such selection in the notice of such prepayment
pursuant to paragraph (e) of this Section; PROVIDED that (i) in the event of any
mandatory prepayment in respect of a Prepayment Event made at a time when any B
Term Borrowing is outstanding, such selection shall be made so that such
prepayments are applied to prepay B Term Borrowings before any Revolving
Borrowings are prepaid, (ii) in the event of any mandatory prepayment in respect
of the Salt Disposition, such selection shall be made in compliance with
paragraph (f) of this Section and (iii) any mandatory prepayment of Revolving
Borrowings required by this Section shall not be construed to require a
reduction of Revolving Commitments.

          (e)  The applicable Borrower shall notify the Administrative Agent
(and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by
telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of
prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City
time, three Business Days before the date of prepayment, (ii) in the case of
prepayment of an ABR Borrowing, not later than 10:00 a.m., New York City time,
on the date of prepayment or (iii) in the case of prepayment of a Swingline
Loan, not later than 12:00 noon, New York City time, on the date of prepayment.
Each such notice shall be irrevocable and shall specify the prepayment date, the
principal amount of each Borrowing or portion thereof to be prepaid and, in the
case of a mandatory prepayment, a reasonably detailed calculation of the amount
of such prepayment; PROVIDED that, if a notice of optional prepayment is given
in connection with a conditional notice of termination of the Revolving
Commitments as contemplated by Section 2.08, then such notice of prepayment may
be revoked if such notice of termination is revoked in accordance with Section
2.08. Promptly following receipt of any such notice (other than a notice
relating solely to Swingline Loans), the Administrative Agent shall advise the
Lenders of the contents thereof. Each partial

<Page>
                                                                              67

prepayment of any Borrowing shall be in an amount that would be permitted in the
case of an advance of a Borrowing of the same Type as provided in Section 2.02,
except as necessary to apply fully the required amount of a mandatory
prepayment. Each prepayment of a Borrowing shall be applied ratably to the Loans
included in the prepaid Borrowing. Prepayments shall be accompanied by accrued
interest to the extent required by Section 2.13.

          (f)  If the Salt Disposition occurs, the Net Proceeds therefrom will
be applied as follows:

          (i)  first, to prepay Revolving Borrowings then outstanding;

         (ii)  second, to prepay B Term Borrowings then outstanding to the
     extent of the excess, if any, of (A) the sum of the aggregate principal
     amount of B Term Borrowings then outstanding plus the aggregate principal
     amount of Polk County IRBs then outstanding plus the total Revolving
     Commitments then in effect minus (B) the Collateral Coverage Amount at the
     time (calculated after excluding from the Collateral Coverage Amount any
     assets included therein that have been sold or otherwise disposed of);

        (iii)  third, remaining Net Proceeds up to the amount of $312,000,000
     shall be deposited in the Salt Disposition Escrow;

         (iv)  fourth, to prepay outstanding B Term Borrowings, subject to
     paragraph (g) below; and

          (v)  fifth, any remaining Net Proceeds shall be available to the
     Company.

          Notwithstanding anything contained herein to the contrary, all Net
Proceeds from the Salt Disposition that are available to be applied to prepay
outstanding B Term Borrowings in accordance with clause (iv) of this paragraph
(f) shall (a) within three Business Days following the consummation of the Salt
Disposition, be deposited in the B Term Loan Escrow for a period not to exceed
30 days and (b) on or prior to the end of such 30-day period, be applied to
prepay outstanding B Term Borrowings, subject to paragraph (g) below (the date
on which such prepayment is made shall be referred to as the "TERM LOAN
PREPAYMENT DATE"). Following such application, any proceeds remaining in the B
Term Loan Escrow shall be released from the B Term Loan Escrow and

<Page>
                                                                              68

shall be available to the Company in accordance with clause (v) of this
paragraph (f).

          In addition, following the Salt Disposition, the Company may, at its
option, deposit in the Excess Salt Disposition Escrow all or any portion of the
Net Proceeds made available to the Company in accordance with clause (v) of this
paragraph (f); PROVIDED that all such funds to be deposited in the Excess Salt
Disposition Escrow shall be deposited in such escrow account no later than the
Term Loan Prepayment Date.

          (g)  Any Term Loan Lender may elect to decline all or any portion of
prepayment of such Lender's B Term Loans required to be made pursuant to clause
(iv) of paragraph (f) above. Such election shall be made by notice to the
Administrative Agent by telephone (confirmed by telecopy) at least one Business
Day prior to the prepayment date. The aggregate amount of the prepayment that
would have been applied to prepay any such B Term Loan that is so declined shall
be available to the Company.

          (h)  In the event of any optional or mandatory prepayment of any B
Term Borrowing hereunder within two years after the Effective Date, the Company
shall on the date of such prepayment pay to the Administrative Agent for the
account of each B Term Loan Lender a prepayment premium equal to (i) if such
prepayment occurs within one year after the Effective Date, 2.0% of the
principal amount of the B Term Loans of such Term Loan Lender so prepaid or (ii)
if such prepayment occurs thereafter but within two years after the Effective
Date, 1.0% of the principal amount of the B Term Loans of such Term Loan Lender
so prepaid; PROVIDED that no such prepayment premium shall be required in
respect of any prepayment of B Term Borrowings pursuant to paragraph (f) of this
Section.

          SECTION 2.12.  FEES.  (a)  The Company agrees to pay to the
Administrative Agent for the account of each Revolving Lender a commitment fee,
which shall accrue at the Applicable Rate on the average daily unused amount of
the Revolving Commitment of such Lender during the period from and including the
Effective Date to but excluding the date on which such Revolving Commitment
terminates; provided that a Defaulting Lender will not be entitled to receive
such fee for any period that it is a Defaulting Lender. Accrued commitment fees
shall be payable in arrears on the last day of March, June, September and
December of each year and on the date on which the

<Page>
                                                                              69

Revolving Commitments terminate, commencing on the first such date to occur
after the date hereof. All commitment fees shall be computed on the basis of a
year of 360 days and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day). For purposes of computing
commitment fees, a Revolving Commitment of a Lender shall be deemed to be used
to the extent of the outstanding Revolving Loans and LC Exposure of such Lender
(and the Swingline Exposure of such Lender shall be disregarded for such
purpose).

          (b)  The Company agrees to pay (i) to the Administrative Agent for the
account of each Revolving Lender a participation fee with respect to its
participations in Letters of Credit, which shall accrue at the same Applicable
Rate as interest on Eurodollar Revolving Loans on the average daily amount of
such Lender's LC Exposure (excluding any portion thereof attributable to
unreimbursed LC Disbursements) during the period from and including the
Effective Date to but excluding the later of the date on which such Lender's
Revolving Commitment terminates and the date on which such Lender ceases to have
any LC Exposure; PROVIDED that a Defaulting Lender shall not be entitled to
receive such fee for any period that it is a Defaulting Lender, and (ii) to each
Issuing Bank a fronting fee, which shall accrue at the rate or rates per annum
separately agreed upon between the Company and such Issuing Bank on the average
daily amount of the LC Exposure attributable to Letters of Credit issued by such
Issuing Bank (excluding any portion thereof attributable to unreimbursed LC
Disbursements) during the period from and including the Effective Date to but
excluding the later of the date of termination of the Revolving Commitments and
the date on which there ceases to be any LC Exposure, as well as such Issuing
Bank's standard fees with respect to the issuance, amendment, renewal or
extension of any Letter of Credit issued by it or processing of drawings
thereunder. Participation fees and fronting fees accrued through and including
the last day of March, June, September and December of each year shall be
payable in arrears on the third Business Day following such last day, commencing
on the first such date to occur after the Effective Date; PROVIDED that all such
fees shall be payable on the date on which the Revolving Commitments terminate
and any such fees accruing after the date on which the Revolving Commitments
terminate shall be payable on demand. Any other fees payable to an Issuing Bank
pursuant to this paragraph shall be payable within 10 days after demand. All
participation fees and fronting fees shall be computed on the basis of a year of

<Page>
                                                                              70

360 days and shall be payable for the actual number of days elapsed (including
the first day but excluding the last day).

          (c)  The Company agrees to pay to the Administrative Agent, for its
own account, fees payable in the amounts and at the times separately agreed upon
between the Company and the Administrative Agent.

          (d)  All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Administrative Agent (or to the applicable
Issuing Bank, in the case of fees payable to it) for distribution, in the case
of commitment fees and participation fees, to the Lenders entitled thereto. Fees
paid shall not be refundable under any circumstances.

          SECTION 2.13. Interest . (a) The Loans comprising each ABR Borrowing
(including each Swingline Loan) shall bear interest at the Alternate Base Rate
plus the Applicable Rate.

          (b)  The Loans comprising each Eurodollar Borrowing shall bear
interest at the Adjusted LIBO Rate for the Interest Period in effect for such
Borrowing plus the Applicable Rate.

          (c)  Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by any Borrower hereunder is not
paid when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the
rate otherwise applicable to such Loan as provided in the preceding paragraphs
of this Section or (ii) in the case of any other amount, 2% plus the rate
applicable to ABR Revolving Loans as provided in paragraph (a) of this Section.

          (d)  Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and, in the case of Revolving Loans, upon
termination of the Revolving Commitments; PROVIDED that (i) interest accrued
pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in
the event of any repayment or prepayment of any Loan (other than a prepayment of
an ABR Revolving Loan prior to the end of the Revolving Availability Period),
accrued interest on the principal amount repaid or prepaid shall be payable on
the date of such repayment or prepayment and (iii) in

<Page>
                                                                              71

the event of any conversion of any Eurodollar Loan prior to the end of the
current Interest Period therefor, accrued interest on such Loan shall be payable
on the effective date of such conversion.

          (e)  All interest hereunder shall be computed on the basis of a year
of 360 days, except that interest computed by reference to the Alternate Base
Rate at times when the Alternate Base Rate is based on the Prime Rate shall be
computed on the basis of a year of 365 days (or 366 days in a leap year), and in
each case shall be payable for the actual number of days elapsed (including the
first day but excluding the last day). The applicable Alternate Base Rate or
Adjusted LIBO Rate shall be determined by the Administrative Agent, and such
determination shall be conclusive absent manifest error.

          SECTION 2.14. ALTERNATE RATE OF INTEREST. If prior to the
commencement of any Interest Period for a Eurodollar Borrowing:

          (a)  the Administrative Agent determines (which determination shall be
     conclusive absent manifest error) that adequate and reasonable means do not
     exist for ascertaining the Adjusted LIBO Rate for such Interest Period; or

          (b)  the Administrative Agent is advised by the Required Lenders that
     the Adjusted LIBO Rate for such Interest Period will not adequately and
     fairly reflect the cost to such Lenders of making or maintaining their
     Loans included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Company and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Company and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective
and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such
Borrowing shall be made as an ABR Borrowing.

          Each Lender shall give notice to the Administrative Agent by telephone
or telecopy as promptly as practicable after determining that the circumstances
referred to in paragraph (b) above applicable to such Lender no longer exist,
and the Administrative Agent

<Page>
                                                                              72

shall give notice to the Company and the Lenders by telephone or telecopy as
promptly as practicable after the Administrative Agent determines (which
determination shall be conclusive absent manifest error) that the circumstances
giving rise to any notice given by the Administrative Agent pursuant to the
preceding sentence no longer exist.

          SECTION 2.15.  INCREASED COSTS.  (a)  If any Change in Law shall:

          (i)  impose, modify or deem applicable any reserve, special deposit or
     similar requirement against assets of, deposits with or for the account of,
     or credit extended by, any Lender (except any such reserve requirement
     reflected in the Adjusted LIBO Rate) or any Issuing Bank; or

         (ii)  impose on any Lender or any Issuing Bank or the London interbank
     market any other condition affecting this Agreement or Eurodollar Loans
     made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make any such Loan) or to increase the cost to such Lender or such
Issuing Bank of participating in, issuing or maintaining any Letter of Credit or
to reduce the amount of any sum received or receivable by such Lender or such
Issuing Bank hereunder (whether of principal, interest or otherwise), then the
relevant Borrower will pay to such Lender or such Issuing Bank, as the case may
be, such additional amount or amounts as will compensate such Lender or such
Issuing Bank (without duplication of any amounts paid to such Lender pursuant to
Section 2.17), as the case may be, for such additional costs incurred or
reduction suffered.

          (b)  If any Lender or any Issuing Bank determines that any Change in
Law regarding capital requirements has or would have the effect of reducing the
rate of return on such Lender's or such Issuing Bank's capital or on the capital
of such Lender's or such Issuing Bank's holding company, if any, as a
consequence of this Agreement or the Loans made by, or participations in Letters
of Credit held by, such Lender, or the Letters of Credit issued by such Issuing
Bank, to a level below that which such Lender or such Issuing Bank or such
Lender's or such Issuing Bank's holding company could

<Page>
                                                                              73

have achieved but for such Change in Law (taking into consideration such
Lender's or such Issuing Bank's policies and the policies of such Lender's or
such Issuing Bank's holding company with respect to capital adequacy), then from
time to time the Company will pay to such Lender or such Issuing Bank, as the
case may be, such additional amount or amounts as will compensate such Lender or
such Issuing Bank or such Lender's or such Issuing Bank's holding company for
any such reduction suffered.

          (c)  A certificate of a Lender or an Issuing Bank setting forth in
reasonable detail the amount or amounts necessary to compensate such Lender or
such Issuing Bank or its holding company, as the case may be, as specified in
paragraph (a) or (b) of this Section shall be delivered to the Company and shall
be conclusive absent manifest error. The relevant Borrower shall pay such Lender
or such Issuing Bank, as the case may be, the amount shown as due on any such
certificate within 10 days after receipt thereof.

          (d)  Failure or delay on the part of any Lender or any Issuing Bank to
demand compensation pursuant to this Section shall not constitute a waiver of
such Lender's or such Issuing Bank's right to demand such compensation; PROVIDED
that the relevant Borrower shall not be required to compensate a Lender or an
Issuing Bank pursuant to this Section for any increased costs or reductions
incurred more than 180 days prior to the date that such Lender or such Issuing
Bank, as the case may be, notifies the Company of the Change in Law giving rise
to such increased costs or reductions and of such Lender's or such Issuing
Bank's intention to claim compensation therefor; PROVIDED FURTHER that, if the
Change in Law giving rise to such increased costs or reductions is retroactive,
then the 180-day period referred to above shall be extended to include the
period of retroactive effect thereof.

          SECTION 2.16.  BREAK FUNDING PAYMENTS.  In the event of (a) the
payment of any principal of any Eurodollar Loan other than on the last day of an
Interest Period applicable thereto (including as a result of an Event of
Default), (b) the conversion of any Eurodollar Loan other than on the last day
of the Interest Period applicable thereto, (c) the failure to borrow, convert,
continue or prepay any Revolving Loan or B Term Loan on the date specified in
any notice delivered pursuant hereto (regardless of whether such notice may be
revoked under Section 2.11(e) and is revoked in accordance

<Page>
                                                                              74

therewith), or (d) the assignment of any Eurodollar Loan other than on the last
day of the Interest Period applicable thereto as a result of a request by the
Company pursuant to Section 2.19, then, in any such event, the relevant Borrower
shall compensate each Lender for the loss, cost and expense attributable to such
event. In the case of a Eurodollar Loan, such loss, cost or expense to any
Lender shall be deemed to include an amount determined by such Lender to be the
excess, if any, of (i) the amount of interest which would have accrued on the
principal amount of such Loan had such event not occurred, at the Adjusted LIBO
Rate that would have been applicable to such Loan, for the period from the date
of such event to the last day of the then current Interest Period therefor (or,
in the case of a failure to borrow, convert or continue, for the period that
would have been the Interest Period for such Loan), over (ii) the amount of
interest which would accrue on such principal amount for such period at the
interest rate which such Lender would bid were it to bid, at the commencement of
such period, for dollar deposits of a comparable amount and period from other
banks in the eurodollar market. A certificate of any Lender setting forth in
reasonable detail any amount or amounts that such Lender is entitled to receive
pursuant to this Section shall be delivered to the Company and shall be
conclusive absent manifest error. The relevant Borrower shall pay such Lender
the amount shown as due on any such certificate within 10 days after receipt
thereof.

          Failure or delay on the part of any Lender to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender's right to
demand such compensation; PROVIDED that the Borrower shall not be required to
compensate a Lender pursuant to this Section for any loss, cost or expense
incurred more than 180 days prior to the date that such Lender notifies the
Company of the loss, cost or expense and of such Lender's intention to claim`
compensation therefor.

          SECTION2.17.  TAXES.  (a)  Any and all payments by or on account of
any obligation of any Borrower hereunder or under any other Loan Document shall
be made free and clear of and without deduction for any Indemnified Taxes or
Other Taxes; PROVIDED that if any Borrower shall be required to deduct any
Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable
shall be increased as necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section)
the Agent, Lender or Issuing Bank (as the case may be)

<Page>
                                                                              75

receives an amount equal to the sum it would have received had no such
deductions been made, (ii) such Borrower shall make such deductions and (iii)
such Borrower shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.

          (b)  In addition, the Borrowers shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

          (c)  The relevant Borrower shall indemnify each Agent, each Lender and
each Issuing Bank, within 10 days after written demand therefor, for the full
amount of any Indemnified Taxes or Other Taxes paid by such Agent, such Lender
or such Issuing Bank, as the case may be, on or with respect to any payment by
or on account of any obligation of any Borrower hereunder or under any other
Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on
or attributable to amounts payable under this Section but excluding Indemnified
Taxes or Other Taxes to the extent resulted from the gross negligence, bad faith
or wilful misconduct of the Agents, such Lender or the Issuing Banks, as
applicable) and any penalties, interest and reasonable expenses arising
therefrom or with respect thereto, whether or not such Indemnified Taxes or
Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate in reasonable detail as to the amount of
such payment or liability delivered to the Company by a Lender or an Issuing
Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender
or an Issuing Bank, shall be conclusive absent manifest error.

          (d)  As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by any Borrower to a Governmental Authority, such Borrower shall
deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

          (e)  Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the
applicable Borrower is located, or any treaty to which such jurisdiction is a
party, with respect to payments under this Agreement shall deliver to the
Company (with a copy to the Administrative Agent), at the time or times
prescribed by

<Page>
                                                                              76

applicable law, such properly completed and executed documentation prescribed by
applicable law or reasonably requested by the Company as will permit such
payments to be made without withholding or at a reduced rate, provided that such
Foreign Lender has received written notice from the Company advising it of the
availability of such exemption or reduction and supplying all applicable
documentation.

          (f)  If the Administrative Agent or any Lender, as the case may be,
determines, in its sole discretion, that it has received a refund of any
Indemnified Taxes or Other Taxes (a "TAX REFUND"), which in the reasonable good
faith judgment of the Administrative Agent or such Lender, as the case may be,
is allocable to Taxes paid by the Borrower, it shall promptly pay such Tax
Refund to the Borrower (but only to the extent of indemnity payments made, or
additional amounts paid, by the Borrower under this Section 2.17 with respect to
the Indemnified Taxes or Other Taxes giving rise to such refund) plus any
interest payable thereon by the relevant Governmental Authority with respect to
such refund, net of all out-of-pocket expenses of the Administrative Agent or
such Lender incurred in obtaining such Tax Refund; PROVIDED, HOWEVER, that the
Borrower, upon the request of the Administrative Agent or such Lender, agrees to
repay the amount paid over to the Borrower (plus any penalties, interest or
other charges imposed by the relevant Governmental Authority) if the
Administrative Agent or such Lender is required to repay such refund to such
Governmental Authority. Nothing contained in this Section 2.17(f) shall require
the Administrative Agent or any Lender to make available its tax returns (or any
other information) to the Borrower or any other Person.

          SECTION 2.18.  PAYMENTS GENERALLY; PRO RATA TREATMENT; SHARING OF
SETOFFS.  (a)  Each Borrower shall make each payment required to be made by it
hereunder or under any other Loan Document (whether of principal, interest, fees
or reimbursement of LC Disbursements, or of amounts payable under Section 2.15,
2.16 or 2.17, or otherwise) prior to the time expressly required hereunder or
under such other Loan Document for such payment (or, if no such time is
expressly required, prior to 12:00 noon, New York City time), on the date when
due, in immediately available funds, without setoff or counterclaim. Any amounts
received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments
shall be made to the

<Page>
                                                                              77

Administrative Agent at its offices at 270 Park Avenue, New York, New York,
except payments to be made directly to an Issuing Bank or Swingline Lender as
expressly provided herein and except that payments pursuant to Sections 2.15,
2.16, 2.17 and 9.03 shall be made directly to the Persons entitled thereto and
payments pursuant to other Loan Documents shall be made to the Persons specified
therein. The Administrative Agent shall distribute any such payments received by
it for the account of any other Person to the appropriate recipient promptly
following receipt thereof. If any payment under any Loan Document shall be due
on a day that is not a Business Day, the date for payment shall be extended to
the next succeeding Business Day, and, in the case of any payment accruing
interest, interest thereon shall be payable for the period of such extension.
All payments under each Loan Document shall be made in dollars.

          (b)  If at any time insufficient funds are received by and available
to the Administrative Agent to pay fully all amounts of principal, unreimbursed
LC Disbursements, interest and fees then due hereunder, such funds shall be
applied (i) first, towards payment of interest and fees then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
interest and fees then due to such parties, and (ii) second, towards payment of
principal and unreimbursed LC Disbursements then due hereunder, ratably among
the parties entitled thereto in accordance with the amounts of principal and
unreimbursed LC Disbursements then due to such parties.

          (c)  If any Lender shall, by exercising any right of setoff or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Revolving Loans, B Term Loans or participations in LC
Disbursements or Swingline Loans resulting in such Lender receiving payment of a
greater proportion of the aggregate amount of its Revolving Loans, B Term Loans
and participations in LC Disbursements and Swingline Loans and accrued interest
thereon than the proportion received by any other Lender, then the Lender
receiving such greater proportion shall purchase (for cash at face value)
participations in the Revolving Loans, B Term Loans and participations in LC
Disbursements and Swingline Loans of other Lenders to the extent necessary so
that the benefit of all such payments shall be shared by the Lenders ratably in
accordance with the aggregate amount of principal of and accrued interest on
their respective Revolving Loans, B Term Loans and participations in LC
Disbursements and Swingline Loans;

<Page>
                                                                              78

PROVIDED that (i) if any such participations are purchased and all or any
portion of the payment giving rise thereto is recovered, such participations
shall be rescinded and the purchase price restored to the extent of such
recovery, without interest, and (ii) the provisions of this paragraph shall not
be construed to apply to any payment made by any Borrower pursuant to and in
accordance with the express terms of this Agreement or any payment obtained by a
Lender as consideration for the assignment of or sale of a participation in any
of its Loans or participations in LC Disbursements to any assignee or
participant, other than to any Borrower or any Subsidiary or Affiliate thereof
(as to which the provisions of this paragraph shall apply). Each Borrower
consents to the foregoing and agrees, to the extent it may effectively do so
under applicable law, that any Lender acquiring a participation pursuant to the
foregoing arrangements may exercise against such Borrower rights of setoff and
counterclaim with respect to such participation as fully as if such Lender were
a direct creditor of such Borrower in the amount of such participation.

          (d)  Unless the Administrative Agent shall have received notice from a
Borrower prior to the date on which any payment is due to the Administrative
Agent from such Borrower for the account of the Lenders or an Issuing Bank
hereunder that such Borrower will not make such payment, the Administrative
Agent may assume that such Borrower has made such payment on such date in
accordance herewith and may, in reliance upon such assumption, distribute to the
Lenders or such Issuing Bank, as the case may be, the amount due. In such event,
if the relevant Borrower has not in fact made such payment, then each of the
Lenders or such Issuing Bank, as the case may be, severally agrees to repay to
the Administrative Agent forthwith on demand the amount so distributed to such
Lender or Issuing Bank with interest thereon, for each day from and including
the date such amount is distributed to it to but excluding the date of payment
to the Administrative Agent, at the greater of the Federal Funds Effective Rate
and a rate determined by the Administrative Agent in accordance with banking
industry rules on interbank compensation.

          (e)  If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.04(c), 2.05(d) or (e), 2.06(b), 2.18(d) or 9.03(c),
then the Administrative Agent may, in its discretion (notwithstanding any
contrary provision hereof), apply any amounts thereafter received by the
Administrative

<Page>
                                                                              79

Agent for the account of such Lender to satisfy such Lender's obligations under
such Sections until all such unsatisfied obligations are fully paid.

          SECTION 2.19.  MITIGATION OBLIGATIONS; REPLACEMENT OF LENDERS.  (a) If
any Lender requests compensation under Section 2.15, or if any Borrower is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.17, then such
Lender shall use reasonable efforts to file any certificate or document
reasonably requested by the Company or to designate a different lending office
for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in
the judgment of such Lender, such filing, designation or assignment (i) would
eliminate or reduce amounts payable pursuant to Section 2.15 or 2.17, as the
case may be, in the future and (ii) would not subject such Lender to any
unreimbursed cost or expense and would not otherwise be disadvantageous to such
Lender. The Company hereby agrees to pay all reasonable costs and expenses
incurred by any Lender in connection with any such filing, designation or
assignment.

          (b)  If any Lender requests compensation under Section 2.15, or if any
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.17,
or if any Lender defaults in its obligations to fund Loans hereunder, then the
Company may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in
Section 9.04), all its interests, rights and obligations under this Agreement to
an assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); PROVIDED that (i) the Company
shall have received the prior written consent of the Administrative Agent (and,
if a Revolving Commitment is being assigned, the Issuing Banks and Swingline
Lender), which consent shall not unreasonably be withheld, (ii) such Lender
shall have received payment of an amount equal to the outstanding principal of
its Loans and participations in LC Disbursements and Swingline Loans, accrued
interest thereon, accrued fees and all other amounts payable to it hereunder,
from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or the Company (in the case of all other amounts) and (iii)
in the case of any such

<Page>
                                                                              80

assignment resulting from a claim for compensation under Section 2.15 or
payments required to be made pursuant to Section 2.17, such assignment will
result in a material reduction in such compensation or payments. A Lender shall
not be required to make any such assignment and delegation if, prior thereto, as
a result of a waiver by such Lender or otherwise, the circumstances entitling
the Company to require such assignment and delegation cease to apply.

          SECTION 2.20. INCREMENTAL FACILITIES.  The Company may at any time, by
notice to the Agents (whereupon the Administrative Agent shall promptly deliver
a copy to each of the Lenders), request the addition of new credit facilities
(the "INCREMENTAL FACILITIES") consisting of a new tranche of term loans (the
"INCREMENTAL TERM LOANS") or a new tranche of revolving loans (the "INCREMENTAL
REVOLVING LOANS") or a combination thereof; PROVIDED that both at the time of
any such request and upon the effectiveness of the Incremental Facility
Amendment referred to below, no Default shall exist and at the time that any
such Incremental Term Loans or Incremental Revolving Loans, as the case may be,
are made (and after giving effect thereto) no Default shall exist and the
Company shall be in compliance with Sections 6.14 and 6.15, determined on a pro
forma basis as if such Incremental Term Loans or Incremental Revolving Loans, as
the case may be, had been outstanding on the last day of the most recent fiscal
quarter for testing compliance therewith. The Incremental Facilities (i) shall
be in an aggregate principal amount not exceeding (in the aggregate)
$100,000,000 and shall be effected as Incremental Term Loans or Incremental
Revolving Loans (except that not more than $50,000,000 of the Incremental
Facilities will be Incremental Revolving Loans), (ii) shall rank PARI PASSU in
right of payment and of security with the Revolving Loans and the B Term Loans,
(iii) that are effected as Incremental Term Loans shall not mature earlier than
the Term Loan Maturity Date (but may, subject to clause (iv) below, have
amortization and commitment reductions prior to such date), (iv) that are
effected as Incremental Term Loans shall not have a weighted average life that
is shorter than that of the B Term Loans, (v) that are effected as Incremental
Revolving Loans shall mature on the Revolving Loan Maturity Date, (vi) shall not
accrue interest at a rate or rates in excess of the interest rates applicable to
the B Term Loans, in the case of Incremental Term Loans, or the Revolving Loans,
in the case of the Incremental Revolving Loans, and (vii) except as set forth
above,

<Page>
                                                                              81

shall be treated substantially the same as (and in any event no more favorably
than) the B Term Loans (in each case, including with respect to mandatory and
voluntary prepayments), in the case of Incremental Term Loans, or the Revolving
Loans, in the case of the Incremental Revolving Loans; PROVIDED that (a) the
terms and conditions applicable to Incremental Term Loans maturing after the
Term Loan Maturity Date may provide for material additional or different
financial or other covenants applicable only during periods after the Term Loan
Maturity Date and (b) subject to clause (vi) above, the Incremental Facilities
may be priced differently than the B Term Loans and the Revolving Loans. Such
notice shall set forth the requested amount of Incremental Term Loans or
Incremental Revolving Loans, as the case may be. In the event that existing
Lenders provide commitments in an aggregate amount less than the total amount of
the Incremental Term Loans or Incremental Revolving Loans, as the case may be,
requested by the Company (but the Company shall not have any obligation to
request any Lender to provide any amount of the Incremental Term Loans or
Incremental Revolving Loans, as the case may be), the Company may arrange for
one or more banks or other financial institutions (any such bank or other
financial institution being called an "ADDITIONAL LENDER") to extend commitments
to provide Incremental Term Loans or Incremental Revolving Loans, as the case
may be, in an aggregate amount equal to the unsubscribed amount. Commitments in
respect of Incremental Term Loans or Incremental Revolving Loans, as the case
may be, shall become Commitments under this Agreement pursuant to an amendment
(an "INCREMENTAL FACILITY AMENDMENT") to this Agreement and, as appropriate, the
other Loan Documents, executed by the Company, each Lender agreeing to provide
such Commitment, if any, each Additional Lender, if any, and the Agents. The
Incremental Facility Amendment may, without the consent of any other Lenders,
effect such amendments to this Agreement and the other Loan Documents as may be
necessary or appropriate, in the opinion of the Agents, to effect the provisions
of this Section. The effectiveness of any Incremental Facility Amendment shall
be subject to the satisfaction on the date thereof of each of the conditions set
forth in Section 4.01 (it being understood that all references to "the date of
such Borrowing" in such Section 4.01 shall be deemed to refer to the effective
date of such Incremental Facility Amendment). No Lender shall be obligated to
provide any Incremental Term Loans or Incremental Revolving Loans, as the case
may be, unless it so agrees.

                                                                              82

          SECTION 2.21.  BORROWING SUBSIDIARIES.  The Company may from time to
time designate any Subsidiary (other than (i) a Foreign Subsidiary that is not a
Foreign Loan Party or (ii) an Excluded Subsidiary) to be a Borrowing Subsidiary
hereunder by delivering to the Administrative Agent a Subsidiary Borrower
Election with respect to such Subsidiary. The eligibility of any Borrowing
Subsidiary to borrow or to have Letters of Credit issued for its account
hereunder shall terminate when the Administrative Agent receives a Subsidiary
Borrower Termination with respect to such Subsidiary. Each Subsidiary Borrower
Election delivered to the Administrative Agent shall be duly executed on behalf
of the relevant Subsidiary and the Company, and each Subsidiary Borrower
Termination delivered to the Administrative Agent shall be duly executed on
behalf of the Company. The delivery of a Subsidiary Borrower Termination shall
not affect any obligation of the relevant Subsidiary theretofore incurred in its
capacity as a Borrower, and such Subsidiary shall continue to constitute a
Borrowing Subsidiary for all purposes hereof (other than the right to borrow
Loans or to have Letters of Credit issued for its account) until all its
obligations hereunder as a Borrower have been discharged and paid in full. The
Administrative Agent shall promptly give notice to the Lenders and the Issuing
Banks of its receipt of any Subsidiary Borrower Election or Subsidiary Borrower
Termination.

          SECTION 2.22.  LIMITATION OF REVOLVING EXPOSURE.  (a)  During the
period immediately following the effective date of the Potash Facility and prior
to the occurrence of a Termination Event (such period, the "LIMITATION PERIOD"),
the Lenders and the Issuing Bank shall not be required to make any Revolving
Loan or Swingline Loan to, or issue any Letter of Credit for the account of, any
Borrower if, upon making such Revolving Loan or Swingline Loan, or issuing such
Letter of Credit, the aggregate Revolving Exposure of the Lenders would exceed
$185,000,000 (the "EXPOSURE LIMIT"). Notwithstanding the restriction set forth
in the immediately preceding sentence, commitment fees payable by the Company
pursuant to Section 2.12 shall continue to accrue and be payable on the
Revolving Commitments.

          (b)  In the event that, at any time during the Limitation Period, the
Company reduces the Revolving Commitments in accordance with Section 2.08, the
Exposure Limit shall be reduced simultaneously by an amount equal to the amount
by which the Revolving Commitments have been so reduced.

                                                                              83

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

          The Company represents and warrants to the Lenders that:

          SECTION 3.01.  ORGANIZATION; POWERS.  Each of the Company and its
Subsidiaries (other than any Excluded Subsidiaries) is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
organization, has all requisite power and authority to carry on its business as
now conducted and, except where the failure to do so, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse
Effect, is qualified to do business in, and is in good standing in, every
jurisdiction where such qualification is required.

          SECTION 3.02.  AUTHORIZATION; ENFORCEABILITY.  The Transactions to be
entered into by each Loan Party are within such Loan Party's corporate powers
and have been duly authorized by all necessary corporate and, if required,
stockholder action. This Agreement has been duly executed and delivered by each
of the Borrowers and constitutes, and each other Loan Document to which any Loan
Party is to be a party, when executed and delivered by such Loan Party, will
constitute, a legal, valid and binding obligation of such Borrower or such Loan
Party (as the case may be), enforceable in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium or other laws
affecting creditors' rights generally and subject to general principles of
equity, regardless of whether considered in a proceeding in equity or at law.

          SECTION 3.03.  GOVERNMENTAL APPROVALS; NO CONFLICTS.  The Transactions
(a) do not require any consent or approval of, registration or filing with, or
any other action by, any Governmental Authority, except (i) such as have been
obtained or made and are in full force and effect, (ii) filings necessary to
perfect Liens created under the Loan Documents and (iii) other consents,
approvals, registrations and filings the failure to obtain which could not
reasonably be expected (individually or in the aggregate) to have a Material
Adverse Effect, (b) will not violate in any material respect any applicable law
or regulation or the charter, by-laws or other organizational documents of the
Borrowers or any of their Subsidiaries or any order of

<Page>
                                                                              84

any Governmental Authority, (c) will not violate or result in a default under
any material indenture, agreement or other instrument binding upon the Company
or any of the Subsidiaries or their assets (except for the Existing Defaults),
or give rise to a right thereunder (other than in respect of the Existing
Defaults) to require any payment to be made by the Company or any of the
Subsidiaries, and (d) will not result in the creation or imposition of (or any
requirement to create or impose) any Lien on any asset of the Company or any of
the Subsidiaries, except Liens created under the Loan Documents.

          SECTION 3.04.  FINANCIAL CONDITION; NO MATERIAL ADVERSE CHANGE.  (a)
The Company has heretofore furnished to the Lenders its consolidated balance
sheet and statements of income, stockholders equity and cash flows (i) as of and
for the fiscal year ended December 31, 2000, reported on by Ernst & Young LLP,
independent public accountants, and (ii) as of and for the fiscal quarter and
the portion of the fiscal year ended March 31, 2001, certified on behalf of the
Company by a Financial Officer. Such financial statements present fairly, in all
material respects, the financial position and results of operations and cash
flows of the Company and its consolidated Subsidiaries as of such dates and for
such periods in accordance with GAAP, subject to year-end audit adjustments and
the absence of footnotes in the case of the statements referred to in clause
(ii) above.

          (b)  Except as disclosed in the financial statements referred to above
or the notes thereto or the Information Memorandum and except for the Disclosed
Matters, none of the Company or its Subsidiaries has, as of the Effective Date,
any material contingent liabilities or material unrealized losses.

          (c)  Since December 31, 2000, there has been no material adverse
change in the business, assets, operations or financial condition of the Company
and the Subsidiaries, taken as a whole.

          SECTION 3.05.  PROPERTIES.  (a)  Each of the Company and its
Subsidiaries has good title to, or valid leasehold interests in, all its real
and personal property material to its business (including its Mortgaged
Properties), except for minor defects in title that do not interfere with its
ability to conduct its business as currently conducted or to utilize such
properties for their intended purposes.

                                                                              85

          (b)  Each of the Company and its Subsidiaries owns, or is licensed to
use, all trademarks, tradenames, copyrights, patents and other intellectual
property material to its business, and the use thereof by the Company and its
Subsidiaries does not infringe upon the rights of any other Person, except for
any such infringements that, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

          (c)  Schedule 3.05 sets forth the address of each real property that
is owned or leased by any Loan Party as of the Effective Date at which
Collateral with an aggregate book value exceeding $5,000,000 is located.

          (d)  As of the Effective Date, neither the Company nor any of its
Subsidiaries has received notice of, or has knowledge of, any pending or
contemplated condemnation proceeding affecting any Mortgaged Property or any
sale or disposition thereof in lieu of condemnation. Neither any Mortgaged
Property nor any interest therein is subject to any right of first refusal,
option or other contractual right to purchase such Mortgaged Property or
interest therein.

          SECTION 3.06.  LITIGATION AND ENVIRONMENTAL MATTERS.  (a)  There are
no actions, suits or proceedings by or before any arbitrator or Governmental
Authority pending against or, to the knowledge of the Company, threatened
against or affecting the Company or any of its Subsidiaries (i) as to which
there is a reasonable possibility of an adverse determination and that, if
adversely determined, could reasonably be expected, individually or in the
aggregate, to result in a Material Adverse Effect (other than the Disclosed
Matters) or (ii) that involve any of the Loan Documents or the Transactions.

          (b)  Except for the Disclosed Matters and except with respect to any
other matters that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect, (i) neither the Company nor any
of its Subsidiaries has failed to comply with any Environmental Law or to
obtain, maintain or comply with any permit, license or other approval required
under any Environmental Law, (ii) there are no pending, or to the knowledge of
the Company, threatened claims, actions, suits, proceedings or investigations
arising under Environmental Laws ("ENVIRONMENTAL CLAIMS") against or affecting
the Company or any Subsidiary, and (iii) to the knowledge of the Company, there
are no facts, circumstances or conditions which could reasonably

<Page>
                                                                              86

be expected to form the basis for an Environmental Claim against the Company or
any Subsidiary.

          SECTION 3.07.  COMPLIANCE WITH LAWS AND AGREEMENTS.  Each of the
Company and its Subsidiaries is in compliance with all laws, regulations and
orders of any Governmental Authority applicable to it or its property and all
indentures, agreements and other instruments binding upon it or its property,
except for the Existing Defaults and Disclosed Matters and except where the
failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect or where the necessity of
compliance therewith is being contested in good faith by appropriate proceedings
and the failure to comply therewith pending such contest could not reasonably be
expected to result in a Material Adverse Effect. No Default has occurred and is
continuing.

          SECTION 3.08.  INVESTMENT AND HOLDING COMPANY STATUS.  Neither the
Company nor any of its Subsidiaries is (a) an "investment company" as defined
in, or subject to regulation under, the Investment Company Act of 1940 or (b) a
"holding company" as defined in, or subject to regulation under, the Public
Utility Holding Company Act of 1935.

          SECTION 3.09.  TAXES.  Each of the Company and its Subsidiaries has
timely filed or caused to be filed all Tax returns and reports required to have
been filed and has paid or caused to be paid all Taxes required to have been
paid by it, except (a) any Taxes that are being contested in good faith by
appropriate proceedings and for which the Company or such Subsidiary, as
applicable, has set aside on its books adequate reserves or (b) to the extent
that the failure to do so could not reasonably be expected to result in a
Material Adverse Effect.

          SECTION 3.10.  ERISA.  No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events for
which liability is reasonably expected to occur, could reasonably be expected to
result in a Material Adverse Effect. The present value of all accumulated
benefit obligations under each Plan (based on the assumptions used for purposes
of calculating the Company's financial statements) did not, as of the date of

          (g)  any event or condition occurs that (i) results in any Material

     Company and has been advised of the claim and has not disclaimed coverage)
     shall be rendered against the Company, any Subsidiary or any combination

     of the Company or any Subsidiary to enforce any such judgment;

          (l)  an ERISA Event shall have occurred that, in the opinion of the
     Required Lenders, when taken together with all other ERISA Events that have

     Collateral Agent's failure to maintain possession of any stock
     certificates, promissory notes or other instruments delivered to it under
     the Pledge Agreement; or

          (n)  a Change in Control shall occur;

then, and in every such event (other than an event with respect to any Borrower
described in clause (h) or (i) of this Article), and at any time thereafter
during the continuance of such event, the Administrative Agent may, and at the
request of the Required Lenders shall, by notice to the Company, take either or
both of the following actions, at the same or different times: (i) terminate the
Commitments, and thereupon the Commitments shall terminate immediately, and (ii)
declare the Loans then outstanding to be due and payable in whole (or in part,
in which case any principal not so declared to be due and payable may thereafter
be declared to be due and payable), and thereupon the principal of the Loans so
declared to be due and payable, together with accrued interest thereon and all
fees and other obligations of the Borrowers accrued hereunder, shall become due
and payable immediately, without presentment, demand, protest or other notice of
any kind, all of which are hereby waived by each Borrower; and in case of any
event with respect to the Company described in clause (h) or (i) of this

notice of any kind, all of which are hereby waived by each Borrower.

          Solely for purposes of determining whether an Event of Default has
occurred under clause (h), (i) or (j) of this Article, any reference in any such

by any event or circumstance referred to in any such clause that (i) is not a
Subsidiary Loan Party, (ii) does not have consolidated assets (determined on a
consolidated basis in accordance with GAAP) representing more than 2% of the
consolidated assets of the Company (determined on a consolidated basis in

consecutive fiscal quarters of the Company, have consolidated revenues
(determined on a consolidated basis in accordance with GAAP) representing more
than 2% of the consolidated revenues of the Company (determined on a
consolidated basis in accordance with GAAP); PROVIDED that if it is necessary to
exclude more than one Subsidiary from clause (h), (i) or (j) of this Article in
order to avoid an Event of Default thereunder, all Subsidiaries affected by any
event or circumstance referred to in any of such clauses shall be treated as a
single consolidated Subsidiary for purposes of determining whether the
conditions specified in clauses (ii) and (iii) of this paragraph are satisfied.

                                  ARTICLE VIII

                                   THE AGENTS

          Each of the Lenders and the Issuing Banks hereby irrevocably appoints
the Administrative Agent as its agent and authorizes the Administrative Agent to
take such actions on its behalf and to exercise such powers as are delegated to
the Administrative Agent by the terms of the Loan Documents, together with such
actions and powers as are reasonably incidental thereto.

          The bank serving as the Administrative Agent hereunder shall have the
same rights and powers in its capacity as a Lender as any other Lender and may
exercise the same as though it were not the Administrative Agent, and such bank
and its Affiliates may accept deposits from, lend money to and generally engage
in any kind of business with the Company or any Subsidiary or other Affiliate
thereof as if it were not the Administrative Agent hereunder.

<Page>
                                                                             130

          The Administrative Agent shall not have any duties or obligations
except those expressly set forth in the Loan Documents. Without limiting the
generality of the foregoing, (a) the Administrative Agent shall not be subject
to any fiduciary or other implied duties, regardless of whether a Default has
occurred and is continuing, (b) the Administrative Agent shall not have any duty
to take any discretionary action or exercise any discretionary powers, except
discretionary rights and powers expressly contemplated by the Loan Documents
that the Administrative Agent is required to exercise in writing by the Required
Lenders (or such other number or percentage of the Lenders as shall be necessary
under the circumstances as provided in Section 9.02), and (c) except as
expressly set forth in the Loan Documents, the Administrative Agent shall not
have any duty to disclose, and shall not be liable for the failure to disclose,
any information relating to the Company or any of its Subsidiaries that is
communicated to or obtained by the bank serving as Administrative Agent or any
of its Affiliates in any capacity. The Administrative Agent shall not be liable
for any action taken or not taken by it with the consent or at the request of
the Required Lenders (or such other number or percentage of the Lenders as shall
be necessary under the circumstances as provided in Section 9.02) or in the
absence of its own gross negligence or wilful misconduct. The Administrative
Agent shall not be deemed not to have knowledge of any Default unless and until
written notice thereof is given to the Administrative Agent by the Company or a
Lender, and the Administrative Agent shall not be responsible for or have any
duty to ascertain or inquire into (i) any statement, warranty or representation
made in or in connection with any Loan Document, (ii) the contents of any
certificate, report or other document delivered thereunder or in connection
therewith, (iii) the performance or observance of any of the covenants,
agreements or other terms or conditions set forth in any Loan Document, (iv) the
validity, enforceability, effectiveness or genuineness of any Loan Document or
any other agreement, instrument or document, or (v) the satisfaction of any
condition set forth in Article IV or elsewhere in any Loan Document, other than
to confirm receipt of items expressly required to be delivered to the
Administrative Agent.

          The Administrative Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by

<Page>
                                                                             131

the proper Person. The Administrative Agent also may rely upon any statement
made to it orally or by telephone and believed by it to be made by the proper
Person, and shall not incur any liability for relying thereon. The
Administrative Agent may consult with legal counsel (who may be counsel for the
Company), independent accountants and other experts selected by it, and shall
not be liable for any action taken or not taken by it in accordance with the
advice of any such counsel, accountants or experts.

          The Administrative Agent may perform any and all its duties and
exercise its rights and powers by or through any one or more sub-agents
appointed by the Administrative Agent. The Administrative Agent and any such
sub-agent may perform any and all its duties and exercise its rights and powers
through their respective Related Parties. The exculpatory provisions of the
preceding paragraphs shall apply to any such sub-agent and to the Related
Parties of each Administrative Agent and any such sub-agent, and shall apply to
their respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as Administrative Agent.

          Subject to the appointment and acceptance of a successor
Administrative Agent as provided in this paragraph, the Administrative Agent may
resign at any time by notifying the Lenders, the Issuing Banks and the Company.
Upon any such resignation, the Required Lenders shall have the right, in
consultation with the Company, to appoint a successor. If no successor shall
have been so appointed by the Required Lenders and shall have accepted such
appointment within 30 days after the retiring Administrative Agent gives notice
of its resignation, then the retiring Administrative Agent may, on behalf of the
Lenders and the Issuing Banks, appoint a successor Administrative Agent which
shall be a bank with an office in New York, New York, or an Affiliate of any
such bank. Upon the acceptance of its appointment as Administrative Agent
hereunder by a successor, such successor shall succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. The fees payable by the Company to a successor
Administrative Agent shall be the same as those payable to its predecessor
unless otherwise agreed between the Company and such successor. After the
Administrative Agent's resignation hereunder, the provisions of this Article and
Section 9.03 shall

continue in effect for the benefit of such retiring Administrative Agent, its
sub-agents and their respective Related Parties in respect of any actions taken
or omitted to be taken by any of them while it was acting as Administrative
Agent.

          Each Lender acknowledges that it has, independently and without
reliance upon the Administrative Agent or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any other Loan Document or related agreement or any document furnished hereunder
or thereunder.

          The provisions of this Article applicable to the Administrative Agent
also shall be applicable to the Syndication Agent and the Collateral Agent,
MUTATIS MUTANDIS. Each of the Lenders and Issuing Banks agrees to the terms and
conditions of the Collateral Sharing Agreement applicable to the Collateral
Agent.

          SECTION 9.02.  WAIVERS; AMENDMENTS.  (a)  No failure or delay by the
any Agent, any Issuing Bank or any Lender in exercising any right or power
hereunder or under any other Loan Document shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Agents, the Issuing Banks and the
Lenders hereunder and under the other Loan Documents are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any provision of any Loan Document or consent to any departure by any Borrower
or any other Loan Party therefrom shall in any event be effective unless the
same shall be permitted by paragraph (b) of this Section, and then such waiver
or consent shall be effective only in the specific instance and for the purpose
for which given. Without limiting the generality of the foregoing, the making of
a Loan or issuance of a Letter of Credit shall not be construed as a waiver of
any Default, regardless of whether any Agent, any Lender or any Issuing Bank may
have had notice or knowledge of such Default at the time.

          (b)  Except as provided in Section 2.20 with respect to an Incremental
Facility Amendment and except as provided in Section 6.06(c) of the Collateral
Sharing Agreement, neither this Agreement nor any other Loan Document nor any
provision hereof or thereof may be waived, amended or modified except, in the
case of this Agreement, pursuant to an agreement or agreements in writing
entered into by the Borrowers and the Required Lenders or, in the case of any
other Loan Document, pursuant to an agreement or agreements in writing entered
into by the applicable Agent that is a party thereto and the Loan Party or Loan
Parties that are parties thereto, in each case with the consent of the Required
Lenders; PROVIDED that no such agreement shall (i) increase the Commitment of
any Lender without the written consent of such Lender, (ii) reduce the principal
amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or
reduce any fees payable hereunder, without the written consent of each Lender
affected thereby, (iii) postpone the maturity of any Loan, or any scheduled date
of payment of the principal amount of any B Term Loan under Section 2.10, or the
required date of reimbursement of any LC Disbursement, or any date for the
payment of any interest or fees payable hereunder, or reduce the amount of,
waive or excuse any such payment, or postpone the scheduled date of expiration
of any Commitment, without the written consent of each Lender affected thereby,
(iv) change Section 2.18(b) or (c) in a manner that would alter the pro rata
sharing of payments required thereby, without the written consent of each
Lender, (v) change any of the provisions of this Section or the percentage set
forth in the definition of "Required Lenders" or any other provision of any Loan
Document specifying the number or percentage of Lenders (or Lenders of any
Class) required to waive, amend or modify any rights thereunder or make any
determination or grant any consent thereunder, without the written consent of
each Lender (or each Lender of such Class, as the case may be), (vi) release the
Company or any material Subsidiary Loan Party from its Guarantee under the
Guarantee Agreement, or limit its liability in respect of such Guarantee, or
release any Subsidiary Loan Party from its Guarantee under the Guarantee
Agreement if such Subsidiary Loan Party's Guarantee in respect of the New Senior
Notes is not concurrently released, in each case without the written consent of
each Lender, (vii) release all or substantially all of the Collateral from the
Liens of the Security Documents, without the written consent of each Lender,
(viii) change any provisions of any Loan Document in a manner that by its terms
adversely affects the rights in respect of payments due to Lenders holding

<Page>
                                                                             135

Loans of any Class differently than those holding Loans of any other Class,
without the written consent of Lenders holding a majority in interest of the
outstanding Loans and unused Commitments of each affected Class, (ix) change the
rights of the Term Loan Lenders to decline mandatory prepayments as provided in
Section 2.11(g) or the application of prepayments of B Term Loans as provided in
Section 2.10(c), without the written consent of Term Loan Lenders holding a
majority of the outstanding B Term Loan Loans or (x) change any of the
provisions of Section 2.11 (or any related definitions) in a manner that would
alter the events or circumstances in respect of which a mandatory prepayment is
required, or the amount or allocation of any such mandatory prepayment, without
the written consent of Lenders holding a majority in interest of the outstanding
Loans and unused Commitments of each Class; PROVIDED FURTHER that (A) no such
agreement shall amend, modify or otherwise affect the rights or duties of any
Agent, any Issuing Bank or the Swingline Lender without the prior written
consent of such Agent, such Issuing Bank or the Swingline Lender, as the case
may be, and (B) any waiver, amendment or modification of this Agreement that by
its terms affects the rights or duties under this Agreement of the Revolving
Lenders (but not the Incremental Revolving Lenders, the Term Loan Lenders and
the Incremental Term Lenders), the Incremental Revolving Lenders (but not the
Revolving Lenders, the Term Loan Lenders and the Incremental Term Lenders), the
Term Loan Lenders (but not the Revolving Lenders, the Incremental Revolving
Lenders and the Incremental Term Lenders) or the Incremental Term Lenders (but
not the Revolving Lenders, the Incremental Revolving Lenders and the Term Loan
Lenders) may be effected by an agreement or agreements in writing entered into
by the Borrowers and requisite percentage in interest of the affected Class of
Lenders that would be required to consent thereto under this Section if such
Class of Lenders were the only Class of Lenders hereunder at the time.
Notwithstanding the foregoing, any provision of this Agreement may be amended by
an agreement in writing entered into by the Borrowers, the Required Lenders and
the Administrative Agent (and, if their rights or obligations are affected
thereby, the Issuing Banks and the Swingline Lender) if (i) by the terms of such
agreement the Commitment of each Lender not consenting to the amendment provided
for therein shall terminate upon the effectiveness of such amendment and (ii) at
the time such amendment becomes effective, each Lender not consenting thereto
receives payment in full of the principal of and interest accrued on each Loan
made

                                                                             136

by it and all other amounts owing to it or accrued for its account under this
Agreement.

          SECTION 9.03.  EXPENSES; INDEMNITY; DAMAGE WAIVER.  (a)  The Company
shall pay (i) all reasonable out-of-pocket expenses incurred by the Agents and
their respective Affiliates, including the reasonable fees, charges and
disbursements of counsel for the Agents, in connection with their due diligence
investigation of the Company, the evaluation of the Collateral, the syndication
of the credit facilities provided for herein, the preparation execution,
delivery, enforcement and administration of the Loan Documents or any
amendments, modifications or waivers of the provisions thereof (whether or not
the transactions contemplated hereby or thereby shall be consummated), (ii) all
reasonable out-of-pocket expenses incurred by any Issuing Bank in connection
with the issuance, amendment, renewal or extension of any Letter of Credit or
any demand for payment thereunder and (iii) all out-of-pocket expenses incurred
by any Agent, any Issuing Bank or any Lender, including the fees, charges and
disbursements of any counsel for any Agent, any Issuing Bank or any Lender, in
connection with the enforcement or protection of its rights in connection with
the Loan Documents, including its rights under this Section, or in connection
with the Loans made or Letters of Credit issued hereunder, including all such
out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Loans or Letters of Credit.

          (b)  The Company shall indemnify each Agent, each Issuing Bank and
each Lender, and each Related Party of any of the foregoing Persons (each such
Person being called an "INDEMNITEE") against, and hold each Indemnitee harmless
from, any and all losses, claims, damages, liabilities and related expenses,
including the fees, charges and disbursements of any counsel for any Indemnitee,
incurred by or asserted against any Indemnitee arising out of, in connection
with, or as a result of (i) the execution or delivery of any Loan Document or
any other agreement or instrument contemplated hereby, the performance by the
parties to the Loan Documents of their respective obligations thereunder or the
consummation of the Transactions or any other transactions contemplated hereby,
(ii) any Loan or Letter of Credit or the use of the proceeds therefrom
(including any refusal by any Issuing Bank to honor a demand for payment under a
Letter of Credit if the documents presented in connection with such demand do
not strictly comply with the terms of such Letter of Credit),

<Page>
                                                                             137

(iii) any actual or alleged presence or release of Hazardous Materials on or
from any Mortgaged Property or any other property currently or formerly owned or
operated by the Company or any of its Subsidiaries, or any Environmental
Liability related in any way to the Company or any of its Subsidiaries, or (iv)
any actual or prospective claim, litigation, investigation or proceeding
relating to any of the foregoing, whether based on contract, tort or any other
theory and regardless of whether any Indemnitee is a party thereto; PROVIDED
that such indemnity shall not, as to any Indemnitee, be available to the extent
that such losses, claims, damages, liabilities or related expenses resulted from
(i) the gross negligence, bad faith or wilful misconduct of such Indemnitee or
(ii) litigation between or among the Lenders or Agents.

          (c)  To the extent that the Company fails to pay any amount required
to be paid by it to any Agent, any Issuing Bank or the Swingline Lender under
paragraph (a) or (b) of this Section, each Lender severally agrees to pay to
such Agent, such Issuing Bank or the Swingline Lender, as the case may be, such
Lender's pro rata share (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount;
PROVIDED that the unreimbursed expense or indemnified loss, claim, damage,
liability or related expense, as the case may be, was incurred by or asserted
against such Agent, such Issuing Bank or the Swingline Lender in its capacity as
such. For purposes hereof, a Lender's "pro rata share" shall be determined based
upon its share of the sum of the total Revolving Exposures, outstanding B Term
Loans and unused Commitments at the time.

          (d)  To the extent permitted by applicable law, none of the Borrowers
shall assert, and each Borrower hereby waives, any claim against any Indemnitee,
on any theory of liability, for special, indirect, consequential or punitive
damages (as opposed to direct or actual damages) arising out of, in connection
with, or as a result of, this Agreement or any agreement or instrument
contemplated hereby, the Transactions, any Loan or Letter of Credit or the use
of the proceeds thereof.

          (e)  All amounts due under this Section shall be payable promptly
after written demand therefor and, in the case of any expenses referred to in
paragraph (a), upon presentation of invoices or other reasonably detailed
statements specifying expenses.

                                                                             138

          SECTION 9.04.  SUCCESSORS AND ASSIGNS.  (a)  The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns permitted hereby (including any
Affiliate of any Issuing Bank that issues any Letter of Credit), except that no
Borrower may assign or otherwise transfer any of its rights or obligations
hereunder without the prior written consent of each Lender (and any attempted
assignment or transfer by any Borrower without such consent shall be null and
void). Nothing in this Agreement, expressed or implied, shall be construed to
confer upon any Person (other than the parties hereto, their respective
successors and assigns permitted hereby (including any Affiliate of any Issuing
Bank that issues any Letter of Credit) and, to the extent expressly contemplated
hereby, the Related Parties of each of the Agents, the Issuing Banks and the
Lenders) any legal or equitable right, remedy or claim under or by reason of
this Agreement.

          (b)  Any Lender may assign to one or more assignees all or a portion
of its rights and obligations under this Agreement (including all or a portion
of its Commitment and the Loans at the time owing to it); PROVIDED that (i)
except in the case of an assignment to a Lender or an Affiliate of a Lender,
each of the Company and the Administrative Agent (and, in the case of an
assignment of all or a portion of a Revolving Commitment or any Lender's
obligations in respect of its LC Exposure or Swingline Exposure, the Issuing
Banks and the Swingline Lender) must give their prior written consent to such
assignment (which consents shall not be unreasonably withheld), (ii) except in
the case of an assignment to a Lender or an Affiliate of a Lender or an
assignment of the entire remaining amount of the assigning Lender's Commitment
or Loans, the amount of the Commitment or Loans of the assigning Lender subject
to each such assignment (determined as of the date the Assignment and Acceptance
with respect to such assignment is delivered to the Administrative Agent) shall
not be less than $5,000,000 (or $1,000,000 in the case of a Term Commitment or B
Term Loan) unless each of the Company and the Administrative Agent otherwise
consent, (iii) each partial assignment shall be made as an assignment of a
proportionate part of all the assigning Lender's rights and obligations under
this Agreement, except that this clause (iii) shall not be construed to prohibit
the assignment of a proportionate part of all the assigning Lender's rights and
obligations in respect of one Class of Commitments or Loans, (iv) the parties to
each assignment shall execute and deliver to the

<Page>
                                                                             139

Administrative Agent an Assignment and Acceptance, together with a processing
and recordation fee of $2,000, and (v) the assignee, if it shall not be a
Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire; and PROVIDED FURTHER that any consent of the Company otherwise
required under this paragraph shall not be required if an Event of Default has
occurred and is continuing. Subject to acceptance and recording thereof pursuant
to paragraph (d) of this Section, from and after the effective date specified in
each Assignment and Acceptance the assignee thereunder shall be a party hereto
and, to the extent of the interest assigned by such Assignment and Acceptance,
have the rights and obligations of a Lender under this Agreement, and the
assigning Lender thereunder shall, to the extent of the interest assigned by
such Assignment and Acceptance, be released from its obligations under this
Agreement (and, in the case of an Assignment and Acceptance covering all of the
assigning Lender's rights and obligations under this Agreement, such Lender
shall cease to be a party hereto but shall continue to be entitled to the
benefits of Sections 2.15, 2.16, 2.17 and 9.03). Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with
this paragraph shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
paragraph (e) of this Section.

          (c)  The Administrative Agent, acting for this purpose as an agent of
the Borrowers, shall maintain at one of its offices in The City of New York a
copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Loans and LC Disbursements owing to, each Lender
pursuant to the terms hereof from time to time (the "REGISTER"). The entries in
the Register shall be conclusive, and the Borrowers, the Agents, the Issuing
Banks and the Lenders may treat each Person whose name is recorded in the
Register pursuant to the terms hereof as a Lender hereunder for all purposes of
this Agreement, notwithstanding notice to the contrary. The Register shall be
available for inspection by the Company, any Issuing Bank and any Lender, at any
reasonable time and from time to time upon reasonable prior notice.

          (d)  Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, the assignee's completed
Administrative Questionnaire (unless the assignee shall already be a

<Page>
                                                                             140

Lender hereunder), the processing and recordation fee referred to in paragraph
(b) of this Section and any written consent to such assignment required by
paragraph (b) of this Section, the Administrative Agent shall accept such
Assignment and Acceptance and record the information contained therein in the
Register. No assignment shall be effective for purposes of this Agreement unless
it has been recorded in the Register as provided in this paragraph.

          (e)  Any Lender may, without the consent of any Borrower, any Agent,
any Issuing Bank or the Swingline Lender, sell participations to one or more
banks or other entities (a "PARTICIPANT") in all or a portion of such Lender's
rights and obligations under this Agreement (including all or a portion of its
Commitment and the Loans owing to it); PROVIDED that (i) such Lender's
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (iii) the Borrowers, the Agents, the Issuing Banks and the
other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement. Any
agreement or instrument pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce the Loan
Documents and to approve any amendment, modification or waiver of any provision
of the Loan Documents; PROVIDED that such agreement or instrument may provide
that such Lender will not, without the consent of the Participant, agree to any
amendment, modification or waiver described in the first proviso to Section
9.02(b) that affects such Participant. Subject to paragraph (f) of this Section,
the Borrowers agree that each Participant shall be entitled to the benefits of
Sections 2.15, 2.16 and 2.17 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to paragraph (b) of this Section.
To the extent permitted by law, each Participant also shall be entitled to the
benefits of Section 9.08 as though it were a Lender, provided such Participant
agrees to be subject to Section 2.18(c) as though it were a Lender.

          (f)  A Participant shall not be entitled to receive any greater
payment under Section 2.15 or 2.17 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant,
unless the sale of the participation to such Participant is made with the
Company's prior written consent. A Participant that would be a Foreign Lender if

<Page>
                                                                             141

it were a Lender shall not be entitled to the benefits of Section 2.17 unless
the Company is notified of the participation sold to such Participant and such
Participant agrees, for the benefit of the Borrowers, to comply with Section
2.17(e) as though it were a Lender.

          (g)  Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations
of such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank, and this Section shall not apply to any such pledge or
assignment of a security interest; PROVIDED that no such pledge or assignment of
a security interest shall release a Lender from any of its obligations hereunder
or substitute any such pledgee or assignee for such Lender as a party hereto.

          SECTION 9.05.  SURVIVAL.  All covenants, agreements, representations
and warranties made by the Loan Parties in the Loan Documents and in the
certificates or other instruments delivered in connection with or pursuant to
this Agreement or any other Loan Document shall be considered to have been
relied upon by the other parties hereto and shall survive the execution and
delivery of the Loan Documents and the making of any Loans and issuance of any
Letters of Credit, regardless of any investigation made by any such other party
or on its behalf and notwithstanding that any Agent, any Issuing Bank or any
Lender may have had notice or knowledge of any Default or incorrect
representation or warranty at the time any credit is extended hereunder, and
shall continue in full force and effect as long as the principal of or any
accrued interest on any Loan or any fee or any other amount payable under this
Agreement is outstanding and unpaid or any Letter of Credit is outstanding and
so long as the Commitments have not expired or terminated. The provisions of
Sections 2.15, 2.16, 2.17 and 9.03 and Article VIII shall survive and remain in
full force and effect regardless of the consummation of the transactions
contemplated hereby, the repayment of the Loans, the expiration or termination
of the Letters of Credit and the Commitments or the termination of this
Agreement or any provision hereof.

          SECTION 9.06.  COUNTERPARTS; INTEGRATION; EFFECTIVENESS.  This
Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of
which when taken together shall constitute a single contract. This Agreement,
the other

<Page>
                                                                             142

Loan Documents and any separate letter agreements with respect to fees payable
to any of the Agents or Issuing Banks constitute the entire contract among the
parties relating to the subject matter hereof and supersede any and all previous
agreements and understandings, oral or written, relating to the subject matter
hereof. This Agreement shall become effective as provided in the Amendment and
Restatement Agreement.

          SECTION 9.07.  SEVERABILITY.  Any provision of this Agreement held to
be invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

          SECTION 9.08.  RIGHT OF SETOFF.  If an Event of Default shall have
occurred and be continuing, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other obligations at any time
owing by such Lender or Affiliate to or for the credit or the account of any
Borrower against any of and all the obligations of such Borrower now or
hereafter existing under this Agreement held by such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement and
although such obligations may be unmatured. The rights of each Lender under this
Section are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

          SECTION 9.09.  GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF
PROCESS.  (a)  This Agreement shall be construed in accordance with and governed
by the law of the State of New York.

          (b)  Each Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Supreme Court
of the State of New York sitting in New York County and of the United States
District Court of the Southern District of New York, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to any
Loan Document, or for recognition or enforcement of any judgment, and each of
the parties hereto hereby

<Page>
                                                                             143

irrevocably and unconditionally agrees that all claims in respect of any such
action or proceeding may be heard and determined in such New York State or, to
the extent permitted by law, in such Federal court. Each of the parties hereto
agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement or any other Loan
Document shall affect any right that any Agent, any Issuing Bank or any Lender
may otherwise have to bring any action or proceeding relating to this Agreement
or any other Loan Document against any Borrower or its properties in the courts
of any jurisdiction.

          (c)  Each Borrower hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement or any other Loan
Document in any court referred to in paragraph (b) of this Section. Each of the

first priority security interest securing the obligations under the Potash
Facility and (c) the Assigned Contract Parties hereby assign to the Collateral
Agent, its successors and permitted assigns, for the ratable benefit of the

Assigned Contract Rights. In addition, as security for the payment in full of
the Senior Obligations other than the Credit Agreement Obligations, (a) each
Grantor hereby grants to the Collateral Agent, its successors and permitted
assigns, for the benefit of the holders of the Senior Obligations other than the
Credit Agreement Obligations, a first priority security interest in all of such
Grantor's right, title and interest in, to and under the Collateral (other than
the Second Priority Collateral to the extent subject to a first priority
security interest securing the obligations under the Potash Facility), in each
case only if and to the extent that Proceeds from such Collateral are required
to be applied pursuant to the Collateral Sharing Agreement to pay such Senior

hereby assign to the Collateral Agent, its successors and permitted assigns, for
the ratable benefit of the Junior Secured Parties, all the Assigned Contract

sentence shall be subject and subordinate to the Liens granted and assignments
made to secure the Senior Obligations pursuant to the preceding two sentences.
The Liens granted hereunder to secure the Senior Obligations and the Junior
Obligations are collectively referred to herein as the "SECURITY INTEREST".

     Notwithstanding anything herein to the contrary, this Agreement is not
intended to create a security interest in the assets of a Grantor to secure the
Obligations if doing so would require any 1997/98 Debt Securities to be equally
and ratably secured, except to the extent that the requirement that 1997/98 Debt
Securities be equally and ratably secured is the result of the Company's failure
to comply with its covenants under the Credit Agreement, and this Agreement
shall be construed and enforced to give effect to such intention. Without
limiting the generality of the foregoing, this Agreement is not intended to
create a security interest in the assets of a Grantor that constitute 1997/98
Restricted Collateral to secure any Obligations (other than the 1997/98
Unrestricted Obligations referred to in clause (a) of the definition of the term
1997/98 Unrestricted Obligations) that do not constitute Indebtedness (within
the meaning of and as

<Page>
                                                                               8

defined in the 1997 Indenture and the 1998 Indenture).

     Notwithstanding anything herein to the contrary, this Agreement is not
intended to create a security interest in the assets of a Grantor to secure the
Obligations if doing so would require any 2001 Debt Securities to be equally and
ratably secured, except to the extent that the requirement that 2001 Debt
Securities be equally and ratably secured is the result of the Company's failure
to comply with its covenants under the Credit Agreement, and this Agreement
shall be construed and enforced to give effect to such intention. Without
limiting the generality of the foregoing, this Agreement is not intended to
create a security interest in the assets of a Grantor that constitute 2001
Restricted Collateral to secure any Obligations (other than the 2001
Unrestricted Obligations referred to in clause (a) of the definition of the term
2001 Unrestricted Obligations) that do not constitute Indebtedness (within the
meaning of and as defined in the New Senior Notes Indentures).

     Without limiting the foregoing, the Collateral Agent is hereby authorized
to file one or more financing statements (including fixture filings),
continuation statements or other documents for the purpose of perfecting,
confirming, continuing, enforcing or protecting the Security Interest granted by
each Grantor, without the signature of any Grantor, and naming any Grantor or
the Grantors as debtors and the Collateral Agent as secured party; PROVIDED,
HOWEVER, that the Collateral Agent shall provide to the Company a copy of each
such filing following each such filing; PROVIDED FURTHER, that the failure of
the Collateral Agent to provide such filings to the Company as provided in this
Section shall not affect any of the rights of the Secured Parties as set forth
in this Agreement. The Security Interest shall also secure all future advances
and re-advances that may hereafter be made by the Secured Parties to or for the
benefit of the Borrowers or any Guarantor.

     SECTION 2.02.  NO ASSUMPTION OF LIABILITY.  The Security Interest is
granted as security only and shall not subject the Collateral Agent or any other
Secured Party to, or in any way alter or modify, any obligation or liability of
any Grantor with respect to or arising out of the Collateral.

     SECTION 2.03.  TENDER ESCROW; SALT DISPOSITION ESCROW; POLK ESCROW.  (a) On
or prior to the Effective Date, the Collateral Agent will establish an escrow
account entitled "IMC Global - Tender Escrow", which will constitute the Tender
Escrow, to be held and administered by the Collateral Agent. In accordance with
Section 5.11 of the Credit Agreement, on the Effective Date, the Company shall
deposit into the Tender Escrow an aggregate amount of $200,000,000 from the
proceeds of Loans made pursuant to the Credit Agreement and the issuance of the
New Senior Notes. The Company may, from time to time when no Default has
occurred and is continuing, request that the Collateral Agent withdraw cash from
the Tender Escrow for the purpose of (i) paying the purchase price for the
6.625% Notes purchased in connection with the 6.625% Notes Tender Offer or (ii)
repaying the 6.625% Notes upon maturity, in each case on the date of such
withdrawal, by delivering to the Collateral Agent a written request for such
withdrawal specifying the amount of the requested withdrawal and the date on
which such withdrawal shall be made and certifying that such withdrawal shall be
in compliance with the restrictions and limitations set forth in this Section.
Upon receipt of any such request for such a withdrawal, the Collateral Agent
shall grant such request if (and only if) it reasonably determines that such
withdrawal would be in compliance with the immediately preceding sentence. In
the event that any cash or Permitted Investments remain in the Tender Escrow
after the date on which all of the 6.625% Notes have been paid in full, and
provided that no Default has occurred

<Page>
                                                                               9

and is continuing, all such cash, together with the proceeds of such Permitted
Investments upon maturity, shall be promptly returned to the Company.

     (b)  On or prior to the Effective Date, the Collateral Agent will establish
an escrow account entitled "IMC Global - Salt Disposition Escrow", which will
constitute the Salt Disposition Escrow, to be held and administered by the
Collateral Agent. In accordance with Section 2.11(f) of the Credit Agreement, in
the event that the Salt Disposition occurs, the Company shall deposit into the
Salt Disposition Escrow all Net Proceeds from the Salt Disposition required to
be deposited in the Salt Disposition Escrow pursuant to such Section. The
Company may request, from time to time when no Default has occurred and is
continuing, that the Collateral Agent withdraw cash from the Salt Disposition
Escrow for the purpose of (i) redeeming or repaying the 7.4% Notes (to the
extent outstanding) or (ii) to the extent of any Net Proceeds deposited in the
Salt Disposition Account in excess of the outstanding principal amount of the
7.4% Notes on the date of deposit, repaying the Company's 6.50% Notes due 2003,
6.55% Notes due 2005 or 7.625% Notes due 2005 (or any combination thereof) then
outstanding, in each case on the date of such withdrawal, by delivering to the
Collateral Agent a written request for such withdrawal specifying the amount of
the requested withdrawal and the date on which such withdrawal shall be made and
certifying that such withdrawal shall be in compliance with the restrictions and
limitations set forth in this Section. Upon receipt of any such request for such
a withdrawal, the Collateral Agent shall grant such request if (and only if) it
reasonably determines that such withdrawal would be in compliance with the
immediately preceding sentence. In the event that any cash or Permitted
Investments remain in the Salt Disposition Escrow after the date on which all of
the 7.4% Notes, 6.50% Notes due 2003, 6.55% Notes due 2005 or 7.625% due 2005
have been paid in full, such cash or Permitted Investments shall be promptly
distributed in accordance with clauses (iv) and (v) of Section 2.11(f) of the
Credit Agreement.

     (c)  On or prior to the Effective Date, the Collateral Agent will establish
an escrow account entitled "IMC Global - Polk Escrow", which will constitute the
Polk Escrow, to be held and administered by the Collateral Agent. In accordance
with Section 5.11 of the Credit Agreement, the Company shall deposit into the
Polk Escrow a portion of the Net Proceeds from the issuance of the New Senior
Notes equal to the aggregate principal amount of the Polk County IRBs that are
outstanding as of the Effective Date and are not owned by a Loan Party (plus, if
the Polk County IRBs are refinanced, the proceeds of such refinancing received
by or on behalf of the Loan Parties in payment of the Polk County IRBs then
owned by the Loan Parties). The Company may request, from time to time when no
Default has occurred and is continuing or, in the event that a Default arising
from an acceleration of the maturity of any Polk County IRBs has occurred and is
continuing, to the extent that such Default will be cured by the application of
funds pursuant to this Section 2.03(c) to purchase, redeem or repay such Polk
County IRBs, that the Collateral Agent withdraw cash from the Polk Escrow for
the purpose of (i) purchasing the Polk County IRBs that are not owned by the
Loan Parties to the extent permitted pursuant to Section 5.15 of the Credit
Agreement, (ii) if the refinancing of the Polk County IRBs is not consummated
prior to January 31, 2002 in accordance with Section 5.15 of the Credit
Agreement, redeeming or repaying the Polk County IRBs at any time on or after
January 31,

<Page>
                                                                              10

2002, or if the Polk County IRBs are accelerated and become due prior to January
31, 2002, redeeming or repaying the Polk County IRBs at any time after such
acceleration, or (iii) if the Polk County IRBs have been so refinanced, first
repaying Revolving Borrowings then outstanding, and second paying, prepaying or
repurchasing (A) the 7.4% Notes or (B) to the extent that the sum of the Salt
Disposition Escrow and the Polk Escrow exceeds the principal amount of the 7.4%
Notes outstanding from time to time, the 6.50% Notes due 2003, the 2005 Senior
Notes or obligations under the Existing Synthetic Purchase Agreement, or to
prepay the B Term Loans (or any combination thereof), in each case on the date
of such withdrawal, by delivering to the Collateral Agent a written request for
such withdrawal specifying the amount of the requested withdrawal and the date
on which such withdrawal shall be made and certifying that such withdrawal shall
be in compliance with the restrictions and limitations set forth in this
Section. Upon receipt of any such request for such a withdrawal, the Collateral
Agent shall grant such request if (and only if) it reasonably determines that
such withdrawal would be in compliance with the immediately preceding sentence.
In the event that any cash or Permitted Investments remain in the Polk Escrow
after the date on which all of the Polk County IRBs have been redeemed or repaid
in full and all obligations under the 7.4% Notes, the 6.50% Notes due 2003, the
2005 Senior Notes, the Existing Synthetic Purchase Agreement and the B Term
Loans have been paid in full, and provided that no Default has occurred and is
continuing, all such cash, together with the proceeds of such Permitted
Investments upon maturity, shall be promptly returned to the Company.

     (d)  On or prior to the date of the Salt Disposition, the Collateral Agent
will establish an escrow account entitled "B Term Loan Escrow", which will
constitute the B Term Loan Escrow, to be held and administered by the Collateral
Agent. In accordance with Section 2.11(f) of the Credit Agreement, on or prior
to the third Business Day after the consummation of the Salt Disposition, the
Company shall deposit into the B Term Loan Escrow all of such Net Proceeds that
are available to be applied to prepay the B Term Borrowings in accordance with
clause (iv) of Section 2.11(f) of the Credit Agreement. Such proceeds shall be
held in the B Term Loan Escrow for a period not to exceed 30 days, and, on the
Term Loan Prepayment Date, such Net Proceeds shall be applied to prepay
outstanding B Term Borrowings, subject to Section 2.11(g) of the Credit
Agreement. Following such application, any proceeds remaining in the B Term Loan
Escrow shall be released from the B Term Loan Escrow and shall be available to
the Company in accordance with clause (v) of Section 2.11(f) of the Credit
Agreement.

     (e)  On or prior to the date that is 15 days after the consummation of the
Salt Disposition, the Collateral Agent will establish an escrow account entitled
"Excess Salt Disposition Escrow", which will constitute the Excess Salt
Disposition Escrow, to be held and administered by the Collateral Agent. In
accordance with Section 2.11(f) of the Credit Agreement, the Company may, at its
option, deposit in the Excess Salt Disposition Escrow all or any portion of the
Net Proceeds made available to the Company in accordance with Section 2.11(f) of
the Credit Agreement, and the Company shall, at its sole discretion, have the
right to request the withdrawal of such escrowed funds, at any time and from
time to time, to prepay, repurchase or redeem the Company's 6.50% Notes due
2003, 10.75% Notes due 2003, 6.55% Notes due 2005 or 7.625% Notes due 2005 (or
any combination thereof) or to use for general corporate purposes.

     (f)  On or prior to the date that is 15 days after the consummation of the
Salt Disposition, the Collateral Agent will establish an escrow account entitled
"Argus Lease Escrow", which will constitute the Argus Lease Escrow, to be held
and administered by the Collateral Agent. In accordance with the definition
"Argus Lease Escrow" in the Credit Agreement, the Company

<Page>
                                                                              11

shall deposit in the Argus Lease Escrow $62,000,000 of the proceeds from the
Salt Disposition in respect of the termination of the Argus Lease or the direct
or indirect acquisition of an undivided interest in the Argus Lease or in the
facilities that are the subject of the Argus Lease, as the case may be. In the
event that, (a) following the completion of all or, if applicable, any portion
of the negotiations among the Company and the lessors under the Argus Lease, it
is determined that the Argus Lease is to be terminated or that IMC Global shall
directly or indirectly acquire an undivided interest in the Argus Lease or in
the facilities that are the subject of the Argus Lease, then such escrowed funds
shall immediately be applied to make any necessary payments in respect of such
termination or any such acquisition, as the case may be (and if, following the
completion of all such negotiations, it is determined that such escrowed funds
exceed the amount of all such payments made or to be made with respect to such
termination or any such acquisition, then the excess shall be applied as
described in clause (b) below), or (b) following the completion of all
negotiations among the Company and the lessors under the Argus Lease, it is
determined that the Argus Lease is not to be terminated and that IMC Global
shall not directly or indirectly acquire an undivided interest in the Argus
Lease or in the facilities that are the subject of the Argus Lease, then such
escrowed funds shall thereafter be deemed to be Net Proceeds from the Salt
Disposition and shall immediately be applied in accordance with Section 2.11(f)
of the Credit Agreement; PROVIDED that any escrowed funds applied in accordance
with Section 2.11(f) (as required by the preceding clause (b)) shall be so
applied in the manner and to the extent that such escrowed funds would have been
applied previously had such escrowed funds been deemed to be Net Proceeds from
the Salt Disposition immediately following the Salt Disposition and not been
deposited in the Argus Lease Escrow. Notwithstanding anything herein to the
contrary, to the extent that any funds are remaining in the Argus Lease Escrow
as of 5:00 p.m., New York City time, on the date that is 365 days after the
consummation of the Salt Disposition, such escrowed funds shall immediately be
applied as set forth in clause (b) of the preceding sentence.

     (g)  The parties hereto agree that, notwithstanding any other term or
condition to the contrary herein or in any other agreement, the Collateral Agent
shall have full dominion and control over the Tender Escrow, the Salt
Disposition Escrow, the B Term Loan Escrow, the Excess Salt Disposition Escrow,
the Argus Lease Escrow and the Polk Escrow with exclusive rights of withdrawal
therefrom, and the Company hereby acknowledges and agrees that no Collateral
shall be released from the Tender Escrow, the Salt Disposition Escrow, the B
Term Loan Escrow, the Excess Salt Disposition Escrow, the Argus Lease Escrow or
the Polk Escrow except as expressly provided in this Agreement or in any other
Loan Document.

     (h)  The Collateral Agent will from time to time invest any cash held in
the Tender Escrow, the Salt Disposition Escrow, the B Term Loan Escrow, the
Excess Salt Disposition Escrow, the Argus Lease Escrow or the Polk Escrow in
Permitted Investments in accordance with any directions received from the
Company; PROVIDED that the Collateral Agent shall not be obligated to make any
such investment except to the extent directed by the Company; PROVIDED FURTHER
that, if no event of Default has occurred and is continuing, any earnings
realized with respect to any such Permitted Investments shall be promptly paid
to the Company. The Collateral Agent shall not be obligated to pay any interest
to the Company on any cash held in the Tender Escrow, the Salt Disposition
Escrow, the B Term Loan Escrow, the Excess Salt Disposition Escrow, the Argus
Lease Escrow or the Polk Escrow. The Collateral Agent shall have the right to
sell or liquidate any such Permitted Investments for the purpose of providing
the cash necessary for any withdrawal by the Company or by the Collateral Agent
made pursuant to this Section; PROVIDED that the Collateral Agent shall have no
responsibility for any diminution in

<Page>
                                                                              12

value of or losses upon sale or liquidation of any such Permitted Investments.
Notwithstanding anything herein to the contrary, the Collateral Agent shall not
be obligated to invest any cash held in the B Term Loan Escrow in any Permitted
Investment if such investment will mature after the Term Loan Prepayment Date.

     (i)  Upon the occurrence of an Event of Default, the Collateral Agent shall
have the right to withdraw amounts from the Tender Escrow, the Salt Disposition
Escrow, the B Term Loan Escrow, the Excess Salt Disposition Escrow, the Argus
Lease Escrow and the Polk Escrow and apply such amounts in accordance with the
terms of Section 3.04 of the Collateral Sharing Agreement.

                         REPRESENTATIONS AND WARRANTIES

     The Grantors jointly and severally represent and warrant to the Collateral
Agent and the Secured Parties that:

     SECTION 3.01.  TITLE AND AUTHORITY.  Each Grantor has good and valid rights
in and title to the Collateral with respect to which it has purported to grant a
Security Interest hereunder and has full power and authority to grant to the
Collateral Agent the Security Interest in such Collateral pursuant hereto and to
execute, deliver and perform its obligations in accordance with the terms of
this Agreement, without the consent or approval of any other Person other than
any consent or approval that has been obtained.

     SECTION 3.02.  FILINGS.  The Perfection Certificate has been duly prepared,
completed and executed and the information set forth therein is correct and
complete, except to the extent that the failure of such information to be true
and correct could not result in a failure to maintain a perfected security
interest in Collateral located in any location at which Collateral having an
aggregate book value exceeding $5,000,000 is located. Fully executed Uniform
Commercial Code and Personal Property Security Act financing statements
(including fixture filings, as applicable) or other appropriate filings,
recordings or registrations containing a description of the Collateral have been
delivered to the Collateral Agent for filing in each governmental, municipal or
other office specified in Schedule 6 to the Perfection Certificate, which are
all the filings, recordings and registrations that are necessary to publish
notice of and protect the validity of and to establish a legal, valid and
perfected security interest in favor of the Collateral Agent (for the ratable
benefit of the Secured Parties, subject to the priorities set forth in Section
2.01 and the provisions of the Collateral Sharing Agreement) in respect of all
Collateral in which the Security Interest may be perfected by filing, recording
or registration in the United States (or any political subdivision thereof),
Canada (or any political subdivision thereof) and their respective territories
and possessions, and no further or subsequent filing, refiling, recording,
rerecording, registration or reregistration is necessary in any such
jurisdiction, except as provided under applicable law with respect to the filing
of continuation statements.

     SECTION 3.03.  VALIDITY OF SECURITY INTEREST.  The Security Interest
constitutes (a) a legal and valid security interest in all the Collateral
securing the payment and performance of the Obligations (subject to the
priorities set forth in Section 2.01 and the provisions of the Collateral
Sharing Agreement) and (b) subject to the filings described in Section 3.02
above, a perfected

<Page>
                                                                              13

security interest in all Collateral in which a security interest may be
perfected by filing, recording or registering a financing statement or analogous
document in the United States (or any political subdivision thereof), Canada (or
any political subdivision thereof) and their respective territories and
possessions pursuant to the Uniform Commercial Code, the Personal Property
Security Act or other applicable law in such jurisdictions. The Security
Interest is and shall be prior to any other Lien on any of the Collateral, other
than Liens expressly permitted to be prior to the Security Interest pursuant to
Section 6.02 of the Credit Agreement.

     SECTION 3.04.  ABSENCE OF OTHER LIENS.  The Collateral is owned by the
Grantors free and clear of any Lien, except for Liens expressly permitted
pursuant to clauses (i), (iii), (iv), (vii) and (xiii) of Section 6.02(a) of the
Credit Agreement and paragraphs (a), (b) and (e) of the definition of the term
"Permitted Encumbrances" in Section 1.01 of the Credit Agreement (such Liens
referred to hereinafter as "SECURED COLLATERAL LIENS"). The Grantors have not
filed or consented to the filing of (a) any financing statement or analogous
document under the Uniform Commercial Code, the Personal Property Security Act
or any other applicable laws covering any Collateral or (b) any assignment in
which any Grantor assigns any Collateral or any security agreement or similar
instrument covering any Collateral with any foreign governmental, municipal or
other office, which financing statement or analogous document, assignment,
security agreement or similar instrument is still in effect, except, in each
case, for Liens expressly permitted pursuant to Section 6.02 of the Credit
Agreement.

     SECTION 3.05.  ASSIGNED CONTRACTS.  Schedule II attached hereto sets forth
each assignable lease or other contract to which any Grantor is party that
provides mineral rights to such Grantor that are associated with the operations
conducted by the Company or any of its Subsidiaries at or in connection with the
Mortgaged Properties (each such contract, as from time to time amended,
extended, renewed, ratified or revived, an "ASSIGNED CONTRACT"). As of the date
of this Agreement, (a) the Assigned Contracts are in full force and effect and
no Assigned Contract Party or, to the knowledge of the Assigned Contract
Parties, any other party to such Assigned Contracts is in breach or default
under the Assigned Contracts and (b) none of the Assigned Contract Parties have
hypothecated, assigned, mortgaged, pledged, encumbered or otherwise transferred
its right, title or interest under the Assigned Contracts in any manner to any
Person other than the Collateral Agent. Within 60 days of the Effective Date the
Company will supplement Schedule II to identify any Assigned Contracts in effect
not listed on the schedule attached hereto.

     SECTION 4.01.  RECORDS; PLACE OF BUSINESS.  Each Grantor agrees to
maintain, at its own cost and expense, such complete and accurate records with
respect to the Collateral owned by it as is consistent with its current
practices and in accordance with such prudent and standard practices used in
industries that are the same as or similar to those in which such Grantor is
engaged, but in any event to include complete accounting records indicating all
payments and proceeds received with respect to any part of the Collateral, and,
at such time or times as the Collateral Agent may reasonably request, promptly
to prepare and deliver to the Collateral Agent a duly certified schedule or
schedules in form and detail reasonably satisfactory to the Collateral

                                                                              14

Agent showing the identity, approximate amount and location of any and all
Collateral (other than Goods which are in transit in the ordinary course of
business) at any location at which Collateral with an aggregate book value
exceeding $5,000,000 is located.

     SECTION 4.02.  PROTECTION OF SECURITY.  Each Grantor shall, at its own cost
and expense, take any and all actions necessary to defend title to the
Collateral against all Persons and to defend the Security Interest of the
Collateral Agent in the Collateral and the priority thereof against any other
Lien, other than against any Secured Collateral Lien.

     SECTION 4.03.  FURTHER ASSURANCES.  Each Grantor agrees, at its own
expense, to execute, acknowledge, deliver and cause to be duly filed all such
further instruments and documents and take all such actions as the Collateral
Agent may from time to time request to better assure, preserve, protect and
perfect the Security Interest and the rights and remedies created hereby,
including the payment of any fees and taxes required in connection with the
execution and delivery of this Agreement, the granting of the Security Interest
and the filing of any financing statements (including fixture filings) or other
documents in connection herewith or therewith. If any amount payable under or in
connection with any of the Collateral shall be or become evidenced by any
promissory note or other instrument, such note or instrument shall be
immediately pledged and delivered to the Collateral Agent, duly endorsed in a
manner satisfactory to the Collateral Agent.

     SECTION 4.04.  TAXES; ENCUMBRANCES.  At its option, the Collateral Agent
may discharge past due taxes, assessments, charges, fees, Liens, security
interests or other encumbrances at any time levied or placed on the Collateral
(other than any Secured Collateral Lien), and may pay for the maintenance and
preservation of the Collateral to the extent any Grantor fails to do so as
required by the Credit Agreement or this Agreement, and each Grantor jointly and
severally agrees to reimburse the Collateral Agent on demand for any payment
made or any expense incurred by the Collateral Agent pursuant to the foregoing
authorization; PROVIDED, HOWEVER, that nothing in this Section 4.04 shall be
interpreted as excusing any Grantor from the performance of, or imposing any
obligation on the Collateral Agent or any Secured Party to cure or perform, any
covenants or other promises of any Grantor with respect to taxes, assessments,
charges, fees, liens, security interests or other encumbrances and maintenance
as set forth herein or in the other Loan Documents.

     SECTION 4.05.  ASSIGNMENT OF SECURITY INTEREST.  If at any time any Grantor
shall take a security interest in any property of an Account Debtor or any other
Person to secure payment and performance of an Account, such Grantor shall
promptly assign such security interest to the Collateral Agent. Such assignment
need not be filed of public record unless necessary to continue the perfected
status of the security interest against creditors of and transferees from the
Account Debtor or other Person granting the security interest.

     SECTION 4.06.  CONTINUING OBLIGATIONS OF THE GRANTORS.  Each Grantor
(including each Assigned Contract Party) shall remain liable to observe and
perform all of the covenants, conditions and obligations to be observed and
performed by it under the Assigned Contracts and

<Page>
                                                                              15

each other contract, agreement or instrument relating to the Collateral, all in
accordance with the terms and conditions thereof, and each Grantor jointly and
severally agrees to indemnify and hold harmless the Collateral Agent and the
Secured Parties from and against any and all liability for such performance.
Without limiting the generality of the foregoing, each Assigned Contract Party
specifically acknowledges and agrees that the Collateral Agent does not assume,
and shall have no responsibility for, the performance of any covenants or
obligations to be performed under or with respect to the Assigned Contracts or
by it and it hereby agrees to indemnify and hold harmless the Collateral Agent
with respect to any and all claims by any Person relating to such covenants or
obligations.

     SECTION 4.07.  USE AND DISPOSITION OF COLLATERAL.  None of the Grantors
shall make or permit to be made an assignment for security, pledge or
hypothecation of the Collateral or shall grant any other Lien (other than a
Secured Collateral Lien) in respect of the Collateral. None of the Grantors
shall make or permit to be made any transfer of the Collateral and each Grantor
shall remain at all times in possession of the Collateral owned by it, except
that (a) Inventory may be sold in the ordinary course of business and (b) unless
and until the Collateral Agent shall notify the Grantors that an Event of
Default shall have occurred and be continuing and that during the continuance
thereof the Grantors shall not sell, convey, lease, assign, transfer or
otherwise dispose of any Collateral (which notice may be given by telephone if
promptly confirmed in writing), the Grantors may use and dispose of the
Collateral in any lawful manner not inconsistent with the provisions of this
Agreement, the Credit Agreement or any other Loan Document.

     SECTION 4.08.  LIMITATION ON MODIFICATION OF ACCOUNTS.  None of the
Grantors will, without the Collateral Agent's prior written consent (which
consent shall not be unreasonably withheld, delayed or conditioned), grant any
extension of the time of payment of any of the Accounts Receivable, compromise,
compound or settle the same for less than the full amount thereof, release,
wholly or partly, any Person liable for the payment thereof or allow any credit
or discount whatsoever thereon, other than extensions, credits, discounts,
compromises or settlements granted or made in the ordinary course of business
and consistent with its current practices.

     SECTION 4.09.  INSURANCE.  The Grantors, at their own expense, shall
maintain or cause to be maintained insurance covering physical loss or damage to
the Inventory in accordance with Section 5.07 of the Credit Agreement, and such
insurance shall (a) provide that no cancelation, material reduction in amount or
material change in coverage thereof shall be effective until at least 30 days
after receipt by the Collateral Agent of written notice thereof, (b) name the
Collateral Agent as insured party on liability policies and loss payee on
property policies and (c) if reasonably requested by the Collateral Agent,
include a breach of warranty clause. Each Grantor irrevocably makes, constitutes
and appoints the Collateral Agent (and all officers, employees or agents
designated by the Collateral Agent) as such Grantor's true and lawful agent (and
attorney-in-fact) for the purpose, during the continuance of an Event of
Default, of making, settling and adjusting claims in respect of Collateral under
policies of insurance, endorsing the name of such Grantor on any check, draft,
instrument or other item of payment for the proceeds of such policies of
insurance and for making all determinations and decisions with respect thereto.
In the event that any Grantor at any time or times shall fail to obtain or
maintain any of the policies of insurance required hereby or to pay any premium
in whole or part relating thereto, the Collateral Agent may, without waiving or
releasing any obligation or liability of the Grantors hereunder or any Event of
Default, in its sole discretion, obtain and maintain such policies of

<Page>
                                                                              16

insurance and pay such premium and take any other actions with respect thereto
as the Collateral Agent deems advisable. All sums disbursed by the Collateral
Agent in connection with this Section 4.09, including reasonable attorneys'
fees, court costs, expenses and other charges relating thereto, shall be
payable, upon demand, by the Company to the Collateral Agent and shall be
additional Obligations secured hereby.

     So long as no Event of Default has occurred and is continuing, all actions
to be taken with respect to the making, settling and adjusting of claims under
insurance policies may be taken by the Grantors without any requirement of
participation or consent from the Collateral Agent and all proceeds received
from any insurance with respect to any claim may be paid directly to the
applicable Grantor to be applied in accordance with the provisions of the Credit
Agreement.

     SECTION 4.10.  LEGEND.  Each Grantor shall legend, in form and manner
satisfactory to the Collateral Agent, its chattel paper and its books, records
and documents evidencing or pertaining thereto with an appropriate reference to
the fact that such chattel paper has been assigned to the Collateral Agent for
the benefit of the Secured Parties and that the Collateral Agent has a security
interest therein.

     SECTION 4.11.  ASSIGNED CONTRACTS.  In addition to, and without limiting,
any and all covenants made by the Grantors pursuant to this Article IV, each
Assigned Contract Party hereby covenants that (a) it will not permit any waiver,
release, termination, expiration, cancelation, pooling, communitization,
supplement, amendment, change or modification to be made to the Assigned
Contracts, except as would not materially adversely affect the rights of such
Assigned Contract Party thereunder and the rights and remedies of the Secured
Parties under this Agreement or any other Loan Document or the ability of the
Secured Parties to exercise the same, and (b) it will not hypothecate, assign,
mortgage, pledge, encumber or otherwise transfer its right, title or interest
under the Assigned Contracts at any time on or after the date of this Agreement
without the prior written consent of the Collateral Agent in each instance, it
being understood and agreed that any such assignment, mortgage, pledge or
encumbrance without the consent of the Collateral Agent shall be void and of no
force or effect.

                                    ARTICLE V

                                    REMEDIES

     SECTION 5.01.  REMEDIES UPON DEFAULT.  Upon the occurrence and during the
continuance of an Event of Default, each Grantor agrees to deliver each item of
Collateral to the Collateral Agent on demand, and it is agreed that the
Collateral Agent shall have the right to take any of or all the following
actions at the same or different times, with or without legal process and with
or without prior notice or demand for performance, to take possession of the
Collateral and without liability for trespass to enter any premises where the
Collateral may be located for the purpose of taking possession of or removing
the Collateral and, generally, to exercise any and all rights afforded to a
secured party under the Uniform Commercial Code, the Personal Property Security
Act or other applicable law and, with respect to the Assigned Contracts, the
terms of such Assigned Contracts. Without limiting the generality of the
foregoing, each Grantor agrees that the Collateral Agent shall have the right,
subject to the mandatory requirements of applicable

<Page>
                                                                              17

law, to sell or otherwise dispose of all or any part of the Collateral, at
public or private sale or at any broker's board or on any securities exchange,
for cash, upon credit or for future delivery as the Collateral Agent shall deem
appropriate. The Collateral Agent shall be authorized at any such sale (if it
deems it advisable to do so) to restrict the prospective bidders or purchasers
to Persons who will represent and agree that they are purchasing the Collateral
for their own account for investment and not with a view to the distribution or
sale thereof, and upon consummation of any such sale the Collateral Agent shall
have the right to assign, transfer and deliver to the purchaser or purchasers
thereof the Collateral so sold. Each such purchaser at any such sale shall hold
the property sold absolutely, free from any claim or right on the part of any
Grantor, and each Grantor hereby waives (to the extent permitted by law) all
rights of redemption, stay and appraisal that such Grantor now has or may at any
time in the future have under any rule of law or statute now existing or
hereafter enacted.

     The Collateral Agent shall give a Grantor 10 days' (or, to the extent
required under the Personal Property Security Act, 20 days') prior written
notice (which each Grantor agrees is reasonable notice within the meaning of
Section 9-504(3) of the Uniform Commercial Code as in effect in the State of New
York or its equivalent in other jurisdictions or, to the extent applicable,
under Section 59(6) of the Personal Property Security Act) of the Collateral
Agent's intention to make any sale of such Grantor's Collateral. Such notice, in
the case of a public sale, shall state the time and place for such sale and, in
the case of a sale at a broker's board or on a securities exchange, shall state
the board or exchange at which such sale is to be made and the day on which the
Collateral, or portion thereof, will first be offered for sale at such board or
exchange. Any such public sale shall be held at such time or times within
ordinary business hours and at such place or places as the Collateral Agent may
fix and state in the notice (if any) of such sale. At any such sale, the
Collateral, or portion thereof, to be sold may be sold in one lot as an entirety
or in separate parcels, as the Collateral Agent may (in its sole and absolute
discretion) determine. The Collateral Agent shall not be obligated to make any
sale of any Collateral if it shall determine not to do so, regardless of the
fact that notice of sale of such Collateral shall have been given. The
Collateral Agent may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for sale, and such sale may, without further notice,
be made at the time and place to which the same was so adjourned. In case any
sale of all or any part of the Collateral is made on credit or for future
delivery, the Collateral so sold may be retained by the Collateral Agent until
the sale price is paid by the purchaser or purchasers thereof, but the
Collateral Agent shall not incur any liability in case any such purchaser or
purchasers shall fail to take up and pay for the Collateral so sold and, in case
of any such failure, such Collateral may be sold again upon like notice. At any
public (or, to the extent permitted by law, private) sale made pursuant to this
Section, any Secured Party may bid for or purchase, free (to the extent
permitted by law) from any right of redemption, stay, valuation or appraisal on
the part of any Grantor (all said rights being also hereby waived and released
to the extent permitted by law), the Collateral or any part thereof offered for
sale and may make payment on account thereof by using any Obligation then due
and payable to such Secured Party from any Grantor as a credit against the
purchase price, and such Secured Party may, upon compliance with the terms of
sale, hold, retain and dispose of such property without further accountability
to any Grantor therefor. For purposes hereof, a written agreement to purchase
the Collateral or any portion thereof shall be treated as a sale thereof; the
Collateral Agent shall be free to carry out such sale pursuant to such agreement
and no Grantor shall be entitled to the return of the Collateral or any portion
thereof subject thereto, notwithstanding the fact that after the Collateral
Agent shall have entered into such an agreement all Events of Default shall have
been remedied and the Obligations paid in full. As an alternative

<Page>
                                                                              18

to exercising the power of sale herein conferred upon it, the Collateral Agent
may proceed by a suit or suits at law or in equity to foreclose this Agreement
and to sell the Collateral or any portion thereof pursuant to a judgment or
decree of a court or courts having competent jurisdiction or pursuant to a
proceeding by a court-appointed receiver; PROVIDED, HOWEVER, that with respect
to the Assigned Contracts, any such sale of such Assigned Contracts shall be
subject to the terms of the Assigned Contracts.

     SECTION 5.02.  APPLICATION OF PROCEEDS.  The Collateral Agent shall apply
the proceeds of any collection or sale of the Collateral, as well as any
Collateral consisting of cash, in the order and manner specified in the
Collateral Sharing Agreement.

     The Collateral Agent shall have absolute discretion as to the time of
application of any such proceeds, moneys or balances in accordance with this
Agreement. Upon any sale of the Collateral by the Collateral Agent (including
pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of the Collateral Agent or of the officer making the sale shall be a
sufficient discharge to the purchaser or purchasers of the Collateral so sold
and such purchaser or purchasers shall not be obligated to see to the
application of any part of the purchase money paid over to the Collateral Agent
or such officer or be answerable in any way for the misapplication thereof.

     SECTION 5.03.  ASSIGNED CONTRACTS.  In addition to all other rights and
remedies provided under Section 5.01 and under any of the Loan Documents, upon
the occurrence and during the continuance of an Event of Default, the Collateral
Agent may, at its option, without notice to or demand upon the Assigned Contract
Parties, in its own name or the name of the Assigned Contract Parties, demand,
sue upon or otherwise enforce, amend, extend, renew, ratify, revive, release,
pool, or communitize the Assigned Contracts to the same extent as if the
Collateral Agent were the party named in the Assigned Contracts, and exercise
all other Assigned Contract Rights in such manner as it may determine; PROVIDED,
HOWEVER, that prior to the occurrence of any such Event of Default, the Assigned
Contract Parties shall be entitled to exercise all the Assigned Contract Rights,
subject to the provisions of Section 4.11. Any moneys actually received by the
Collateral Agent pursuant to the exercise of any of the rights and remedies
granted pursuant this Section shall be applied as provided in Section 5.02.

                                   ARTICLE VI

                                  MISCELLANEOUS

     SECTION 6.01.  NOTICES.  All communications and notices hereunder shall
(except as otherwise expressly permitted herein) be in writing and given as
provided in Section 9.01 of the Credit Agreement. All communications and notices
hereunder to any Subsidiary Guarantor shall be given to it in care of the
Company in accordance with the preceding sentence (and each Subsidiary Guarantor
acknowledges that the Company is authorized to accept such

<Page>
                                                                              19

communications and notices on its behalf).

     SECTION 6.02.  SECURITY INTEREST ABSOLUTE.  All rights of the Collateral
Agent hereunder, the Security Interest and all obligations of the Grantors
hereunder shall be absolute and unconditional irrespective of (a) any lack of
validity or enforceability of the Credit Agreement, any other Loan Document, any
agreement with respect to any of the Obligations or any other agreement or
instrument relating to any of the foregoing, (b) any change in the time, manner
or place of payment of, or in any other term of, all or any of the Obligations,
or any other amendment or waiver of or any consent to any departure from the
Credit Agreement, any other Loan Document or any other agreement or instrument,
(c) any exchange, release or non-perfection of any Lien on other collateral, or
any release or amendment or waiver of or consent under or departure from any
guarantee, securing or guaranteeing all or any of the Obligations, or (d) any
other circumstance that might otherwise constitute a defense available to, or a
discharge of, any Grantor in respect of the Obligations or this Agreement.

     SECTION 6.03. SURVIVAL OF AGREEMENT. All covenants, agreements,
representations and warranties made by any Grantor herein and in the
certificates or other instruments prepared or delivered in connection with or
pursuant to this Agreement or any other Loan Document shall be considered to
have been relied upon by the Collateral Agent and the other Secured Parties and
shall survive the making by the Lenders of the Loans and the issuance of the
Letters of Credit by the Issuing Banks, and the execution and delivery to the
Lenders of any notes evidencing such Loans, regardless of any investigation made
by the Lenders or on their behalf, and shall continue in full force and effect
until this Agreement shall terminate.

     SECTION 6.04.  BINDING EFFECT; SEVERAL AGREEMENT.  This Agreement shall
become effective as to any Grantor when a counterpart hereof executed on behalf
of such Grantor shall have been delivered to the Collateral Agent and a
counterpart hereof shall have been executed on behalf of the Collateral Agent,
and thereafter shall be binding upon such Grantor and the Collateral Agent and
their respective successors and assigns, and shall inure to the benefit of such
Grantor, the Collateral Agent and the other Secured Parties and their respective
successors and assigns, except that no Grantor shall have the right to assign or
transfer its rights or obligations hereunder or any interest herein or in the
Collateral (and any such assignment or transfer shall be void) except as
expressly contemplated by this Agreement or the Credit Agreement. This Agreement
shall be construed as a separate agreement with respect to each Grantor and may
be amended, modified, supplemented, waived or released with respect to any
Grantor without the approval of any other Grantor and without affecting the
obligations of any other Grantor hereunder.

     SECTION 6.05.  SUCCESSORS AND ASSIGNS.  Whenever in this Agreement any of
the parties hereto is referred to, such reference shall be deemed to include the
successors and assigns of such party; and all covenants, promises and agreements
by or on behalf of any Grantor or the Collateral Agent that are contained in
this Agreement shall bind and inure to the benefit of their respective
successors and assigns.

     SECTION 6.06.  COLLATERAL SHARING AGREEMENT.  By becoming a party to this
Agreement, each Grantor agrees to be bound by the terms of the Collateral
Sharing Agreement and, without limiting the generality of the foregoing,
expressly agrees that all obligations and liabilities of a Loan Party thereunder
apply to such Grantor with the same force and effect as if such Grantor were a
signatory thereto.

                                                                              20

     SECTION 6.07.  COLLATERAL AGENT'S FEES AND EXPENSES; INDEMNIFICATION.  (a)
Each Grantor jointly and severally agrees to pay upon demand to the Collateral
Agent the amount of any and all reasonable expenses, including the reasonable
fees, disbursements and other charges of its counsel and of any experts or
agents, which the Collateral Agent may incur in connection with (i) the
administration of this Agreement (including the customary fees and charges of
the Collateral Agent for any audits conducted by it or on its behalf with
respect to the Accounts Receivable or Inventory), (ii) the custody or
preservation of, or the sale of, collection from or other realization upon any
of the Collateral, (iii) the exercise, enforcement or protection of any of the
rights of the Collateral Agent hereunder or (iv) the failure of any Grantor to
perform or observe any of the provisions hereof.

     (b)  Without limitation of its indemnification obligations under the other
Loan Documents, each Grantor jointly and severally agrees to indemnify the
Collateral Agent and the other Indemnitees (as defined in Section 9.03(b) of the
Credit Agreement) against, and hold each of them harmless from, any and all
losses, claims, damages, liabilities and related expenses, including reasonable
fees, disbursements and other charges of counsel, incurred by or asserted
against any of them arising out of, in any way connected with, or as a result
of, the execution, delivery or performance of this Agreement or any claim,
litigation, investigation or proceeding relating hereto or to the Collateral,
whether or not any Indemnitee is a party thereto, PROVIDED that such indemnity
shall not, as to any Indemnitee, be available to the extent that such losses,
claims, damages, liabilities or related expenses have resulted from the gross
negligence, bad faith or willful misconduct of such Indemnitee.

     (c)  Any such amounts payable as provided hereunder shall be additional
Obligations secured hereby and by the other Security Documents. The provisions
of this Section 6.07 shall remain operative and in full force and effect
regardless of the termination of this Agreement or any other Loan Document, the
consummation of the transactions contemplated hereby, the repayment of any of
the Loans, the invalidity or unenforceability of any term or provision of this
Agreement or any other Loan Document, or any investigation made by or on behalf
of the Collateral Agent or any Lender. All amounts due under this Section 6.07
shall be payable on written demand therefor.

     SECTION 6.08.  GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

     SECTION 6.09.  WAIVERS; AMENDMENT.  (a)  No failure or delay of the
Collateral Agent in exercising any power or right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and remedies of the Collateral Agent hereunder
and of the other Secured Parties under the other Loan Documents are cumulative
and are not exclusive of any rights or remedies that they would otherwise have.
No waiver of any provisions of this Agreement or any other Loan Document or
consent to any departure by any Grantor therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) below, and then
such waiver or consent shall be effective only in the specific instance and for
the purpose for which given. No notice to or demand on any Grantor in any case
shall entitle such Grantor or any other Grantor to any other or further notice
or demand in similar or other circumstances.

<Page>
                                                                              21

     (b)  Neither this Agreement nor any provision hereof may be waived, amended
or modified except pursuant to an agreement or agreements in writing entered
into by the Collateral Agent and the Grantor or Grantors with respect to which
such waiver, amendment or modification is to apply, subject to any consent
required in accordance with Section 9.02 of the Credit Agreement.

     (c)  Notwithstanding the foregoing, if (i) any Polk County IRB is
refinanced by the issuance of Indebtedness permitted by the Credit Agreement as
contemplated by Section 5.15 of the Credit Agreement and (ii) the terms of such
Indebtedness require that the payment of such Indebtedness be secured by a
security interest in any Collateral, then the Collateral Agent and the Grantors
shall enter into an amendment to this Agreement, in form and substance
reasonably satisfactory to the Collateral Agent and the Grantors, providing for
the grant pursuant to this Agreement of such security interest and such other
changes to this Agreement as are necessary to provide the holders of such
Indebtedness with the benefits of this Agreement with respect to such security
interest; PROVIDED that (A) the terms of such security interest and such other
changes to this Agreement shall not be more favorable to the holders of such
Indebtedness than the terms of this Agreement are to the holders of the Polk
County IRBs and (B) no consent of any Secured Party other than the Collateral
Agent shall be required for such amendment.

     (d)  The Grantors hereby agree that The Limitation of Civil Rights Act of
the Province of Saskatchewan shall have no application to this Agreement or any
instrument renewing, extending, or collateral to this Agreement, and any rights
or benefits under The Limitation of Civil Rights Act of the Province of
Saskatchewan are hereby waived.

     SECTION 6.10.  WAIVER OF JURY TRIAL; APPOINTMENT OF RECEIVER. EACH PARTY
HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR
INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF
THE OTHER LOAN DOCUMENTS. EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION 6.10.

     SECTION 6.11. SEVERABILITY. In the event any one or more of the provisions
contained in this Agreement should be held invalid, illegal or unenforceable in
any respect, the validity, legality and enforceability of the remaining
provisions contained herein shall not in any way be affected or impaired thereby
(it being understood that the invalidity of a particular provision in a
particular jurisdiction shall not in and of itself affect the validity of such
provision in any other jurisdiction). The parties shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions. It is understood and agreed
among the parties that this Agreement shall create separate security interests
in the Collateral securing (i) the Credit Agreement Obligations (other than the
Junior Obligations), (ii) the Senior

<Page>
                                                                              22

Obligations other than the Credit Agreement Obligations and (iii) the Junior
Obligations, respectively, as provided in Section 2.01, and that any
determination by any court with jurisdiction that the Security Interest securing
any Obligation or class of Obligations is invalid for any reason shall not in
and of itself invalidate the Security Interest securing any other Obligations
hereunder.

     SECTION 6.12.  COUNTERPARTS.  This Agreement may be executed in two or more
counterparts, each of which shall constitute an original but all of which when
taken together shall constitute but one contract (subject to Section 6.04), and
shall become effective as provided in Section 6.04. Delivery of an executed

this Agreement.

     SECTION 6.14.  JURISDICTION; CONSENT TO SERVICE OF PROCESS.  (a)  Each
Grantor hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the other Loan Documents, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Agreement shall affect any right that the
Collateral Agent, the Administrative Agent, the Issuing Bank or any Lender may
otherwise have to bring any action or proceeding relating to this Agreement or
the other Loan Documents against any Grantor or its properties in the courts of
any jurisdiction.

     (b)  Each Grantor hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or the other Loan Documents in any
New York State or Federal court referred to in paragraph (a) of this Section.
Each of the parties hereto hereby irrevocably waives, to the fullest extent
permitted by law, the defense of an inconvenient forum to the maintenance of
such action or proceeding in any such court.

     (c)  Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 6.01. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process

shall

                                                                              23

automatically terminate when all the Obligations (other than contingent
indemnification and other contingent obligations as to which the Grantors have
not received a notice of claim) described in clause (a) of the definition
thereof have been indefeasibly paid in full, the Lenders have no further
commitment to lend under the Credit Agreement, the LC Exposure has been reduced
to zero and the Issuing Bank has no further commitment to issue Letters of
Credit under the Credit Agreement, at which time the Collateral Agent shall
execute and deliver to the Grantors or the Grantors' designee, at the Grantors'
expense, all Uniform Commercial Code termination statements and similar
documents which the Grantors shall reasonably request from time to time to
evidence such termination. Any execution and delivery of termination statements
or documents pursuant to this Section 6.15(a) shall be without recourse to or
warranty by the Collateral Agent.

     (b)  A Subsidiary Guarantor shall automatically be released from its
obligations hereunder and the Security Interest in the Collateral of such
Subsidiary Guarantor shall be automatically released in the event that all the
Equity Interests of such Subsidiary Guarantor shall be sold, transferred or
otherwise disposed of to a Person that is not an Affiliate of the Company in
accordance with the terms of the Credit Agreement, PROVIDED that the Required
Lenders or, if required by the terms of the Credit Agreement, all the Lenders
shall have consented to such sale, transfer or other disposition (to the extent
required by the Credit Agreement) and the terms of such consent did not provide
otherwise. The Security Interest in any Collateral that is sold, transferred or
otherwise disposed of in accordance with this Agreement, the Credit Agreement
and the other Loan Documents (including pursuant to a waiver or amendment of the
terms thereof) shall automatically terminate and be released, and such
Collateral shall be sold free and clear of the Lien and Security Interest
created hereby. In connection with any of the foregoing, the Collateral Agent
shall execute and deliver to the Grantors or the Grantors' designee, at the
Grantors' expense, all Uniform Commercial Code and the Personal Property
Security Act termination statements and similar documents that the Grantors
shall reasonably request from time to time to evidence such termination. Any
execution and delivery of termination statements or documents pursuant to this
Section 6.15(b) shall be without recourse to or warranty by the Collateral
Agent.

     SECTION 6.16.  ADDITIONAL GRANTORS.  Pursuant to Section 5.12 of the Credit
Agreement, each Subsidiary Loan Party that was not in existence or that was not
a Subsidiary Loan Party on the date of the Credit Agreement is required to enter
into this Agreement as a Grantor upon becoming a Subsidiary Loan Party if such
Subsidiary Loan Party owns or possesses property of a type that would be
considered Collateral hereunder. Upon execution and delivery by the Collateral
Agent and a Subsidiary Loan Party of an instrument in the form of Annex 1
hereto, such Subsidiary Loan Party shall become a Grantor hereunder with the
same force and effect as if originally named as a Grantor herein. The execution
and delivery of any such instrument shall not require the consent of any Grantor
hereunder. The rights and obligations of each Grantor hereunder shall remain in
full force and effect notwithstanding the addition of any new Grantor as a party
to this Agreement.

     SECTION 6.17.  COLLATERAL AGENT APPOINTED ATTORNEY-IN-FACT.  Upon the
occurrence and during the continuation of an Event of Default, the Collateral
Agent shall have the right, as the true and lawful attorney-in-fact and agent of
the Assigned Contract Parties, with power of substitution for the Assigned
Contract Parties and in the Assigned Contract Parties' names, the Collateral
Agent's name or otherwise for the use and benefit of the Collateral Agent (a) to
receive, endorse, assign and/or deliver any and all notes, acceptances, checks,
drafts, money

orders or other evidences of payment relating to the Assigned Contracts or any
part thereof; (b) to demand, collect, receive payment of, give receipt for and
give discharges and releases of all or any of the Assigned Contracts; (c) to
sign the name of the Assigned Contract Parties on any invoice or bill of lading
relating to any of the Assigned Contracts; (d) to commence and prosecute any and
all suits, actions or proceedings at law or in equity in any court of competent
jurisdiction to collect or otherwise realize on all or any of the Assigned
Contracts or to enforce any rights in respect of any Assigned Contracts; (e) to
settle, compromise, compound, adjust or defend any actions, suits or proceedings
relating to all or any of the Assigned Contracts; and (f) to use, sell, assign,
transfer, pledge, amend, extend, renew, ratify, revive, release, pool or
communitize or make any agreement with respect to or otherwise deal with all or
any of the Assigned Contracts, and to do all other acts and things necessary to
carry out the purposes of this Agreement, as fully and completely as though the
Collateral Agent were the Assigned Contract Party named in the Assigned
Contracts; PROVIDED, HOWEVER, that nothing herein contained shall be construed
as requiring or obligating the Collateral Agent or any other Secured Party to
make any commitment or to make any inquiry as to the nature or sufficiency of
any payment received by the Collateral Agent or any other Secured Party, or to
present or file any claim or notice, or to take any action with respect to the
Assigned Contracts or any part thereof or the moneys due or to become due in
respect thereof or any property covered thereby, and no action taken or omitted
to be taken by the Collateral Agent or any other Secured Party with respect to
the Assigned Contracts or any part thereof shall give rise to any defense,
counterclaim or offset in favor of the Assigned Contract Parties or, except as a
result of gross negligence, bad faith or wilful misconduct, to any claim or
action against the Collateral Agent or any other Secured Party. It is understood
and agreed that the appointment of the Collateral Agent as the agent and
attorney-in-fact of the Assigned Contract Parties for the purposes set forth
above is coupled with an interest and is irrevocable. The provisions of this
Section 6.17 shall in no event relieve the Assigned Contract Parties of any of
their obligations hereunder or under the other Loan Documents with respect to
the Assigned Contracts or any part thereof or impose any obligation on the
Collateral Agent or any other Secured Party to proceed in any particular manner
with respect to the Assigned Contracts or any part thereof, or in any way limit
the exercise by the Collateral Agent or any other Secured Party of any other or
further right that it may have on the date of this Agreement or hereafter,
whether hereunder, under any other Loan Document, by law or otherwise.

     SECTION 6.18.  RECEIPT OF AGREEMENT.  The Grantors hereby acknowledge
receipt of an executed copy of this Agreement.

     SECTION 6.19.  CURRENT SECURITY AGREEMENT; EFFECTIVENESS OF AMENDMENT AND
RESTATEMENT.  Until this Agreement becomes effective in accordance with the
terms of the Amendment and Restatement Agreement, the Current Security Agreement
shall remain in full force and effect and shall not be affected hereby. On and
after the Restatement Effective Date, the provisions of the Current Security
Agreement shall be superseded by the provisions hereof; PROVIDED that this
Agreement shall not be construed to terminate and replace the Current Security
Agreement, but is intended to and shall be construed to continue in effect all
Security Interests, Liens and other obligations previously created under the
Current Security Agreement on the terms set forth herein.

                         SUPPLEMENT NO. [ ] dated as of [ ] (this "SUPPLEMENT"),
                    to the Amended and Restated Security Agreement dated as of
                    February 21, 2003, among, IMC GLOBAL INC., a Delaware
                    corporation (the "COMPANY"), each subsidiary of the Company
                    listed on Schedule I thereto (each such subsidiary,
                    individually, a "SUBSIDIARY GUARANTOR" and, collectively,
                    the "SUBSIDIARY GUARANTORS") (the Subsidiary Guarantors and
                    the Company are referred to collectively herein as the
                    "GRANTORS") and JPMorgan Chase Bank (successor to The Chase
                    Manhattan Bank), a New York banking corporation, as
                    collateral agent (in such capacity, the "COLLATERAL AGENT")
                    for the Secured Parties (as defined herein).

          A. Reference is made to (a) the Amended and Restated Credit Agreement
dated as of May 17, 2001, amended and restated as of February 21, 2003 (as
amended, supplemented or otherwise modified from time to time, the "CREDIT
AGREEMENT"), among the Company, the Borrowing Subsidiaries referred to therein,
the lenders from time to time party thereto, JPMorgan Chase Bank, as
administrative agent for the Lenders, and Goldman Sachs Credit Partners L.P., as
syndication agent, and (b) the Guarantee Agreement dated as of May 17, 2001 (as
amended, supplemented or otherwise modified from time to time, the "GUARANTEE
AGREEMENT"), among the Company, the Subsidiary Guarantors and the Collateral
Agent.

          B. Capitalized terms used herein and not otherwise defined herein
shall have the meanings assigned to such terms in the Security Agreement and the
Credit Agreement.

          C. The Grantors have entered into the Security Agreement in order to
induce the Lenders to make Loans and the Issuing Banks to issue Letters of
Credit. Pursuant to Section 5.12 of the Credit Agreement, each Subsidiary Loan
Party that was not in existence or that was not a Subsidiary Loan Party on the
date of the Credit Agreement is required to enter into the Security Agreement as
a Grantor upon becoming a Subsidiary Loan Party if such Subsidiary Loan Party
owns or possesses property of a type that would be considered Collateral under
the Security Agreement. Section 6.16 of the Security Agreement provides that
additional Subsidiary Loan Parties may become Grantors under the Security
Agreement by execution and delivery of an instrument in the form of this
Supplement. The undersigned Subsidiary Loan Party (the "NEW GRANTOR") is
executing this Supplement in accordance with the requirements of the Credit
Agreement to become a Grantor under the Security Agreement in order to induce
the Lenders to make additional Loans and the Issuing Banks to issue additional
Letters of Credit and as consideration for Loans previously made and Letters of
Credit previously issued.

          Accordingly, the Collateral Agent and the New Grantor agree as
follows:

<Page>
                                                                              29

          SECTION 1. In accordance with Section 6.16 of the Security Agreement,
the New Grantor by its signature below becomes a Grantor under the Security
Agreement with the same force and effect as if originally named therein as a
Grantor and the New Grantor hereby (a) agrees to all the terms and provisions of
the Security Agreement applicable to it as a Grantor thereunder and (b)
represents and warrants that the representations and warranties made by it as a
Grantor thereunder are true and correct on and as of the date hereof. In
furtherance of the foregoing, the New Grantor:

          (i) as security for the payment in full of the Credit Agreement
Obligations (other than the Junior Obligations), does hereby create and grant to
the Collateral Agent, its successors and assigns, for the ratable benefit of the
Senior Secured Parties that hold such Credit Agreement Obligations, their
successors and assigns, a first priority security interest in and lien on all of
the New Grantor's right, title and interest in and to the Collateral of the New
Grantor;

          (ii) as security for the payment in full of the Senior Obligations
other than the Credit Agreement Obligations, does hereby create and grant to the
Collateral Agent, its successors and assigns for the benefit of the holders of
the Senior Obligations other than the Credit Agreement Obligations, their
successors and assigns, a first priority security interest in and lien on all of
the New Grantor's right, title and interest in and to the Collateral of the New
Grantor, in each case only if and to the extent that Proceeds from such
Collateral are required to be applied pursuant to the Collateral Sharing
Agreement to pay such Senior Obligations; and

          (iii) as security for the payment in full of the Junior Obligations,
does hereby create and grant to the Collateral Agent, its successors and assigns
for the ratable benefit of the Junior Secured Parties, their successors and
assigns, a second priority security interest in and lien on all of the New
Grantor's right, title and interest in and to the Collateral of the New Grantor;
PROVIDED that the Liens granted pursuant to this clause (iii) shall be subject
and subordinate to the Liens granted to secure the Senior Obligations pursuant
to clauses (i) and (ii) of this Section.

Each reference to a "Grantor" in the Security Agreement shall be deemed to
include the New Grantor. The Security Agreement is hereby incorporated herein by
reference.

          SECTION 2. The New Grantor represents and warrants to the Collateral
Agent and the other Secured Parties that this Supplement has been duly
authorized, executed and delivered by it and constitutes its legal, valid and
binding obligation, enforceable against it in accordance with its terms, subject
to applicable bankruptcy, insolvency, reorganization, moratorium or other laws
affecting creditors' rights generally and subject to general principles of
equity, regardless of whether considered in a proceeding in equity or at law.

          SECTION 3. This Supplement may be executed in counterparts (and by
different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a
single contract. This Supplement shall become effective when the Collateral
Agent shall have received counterparts of this Supplement that, when taken
together, bear the signatures of the New Grantor and the Collateral Agent.
Delivery of an executed signature page to this Supplement by facsimile
transmission shall be as effective as delivery of a manually signed counterpart
of this Supplement.

          SECTION 4. The New Grantor hereby represents and warrants that (a) set
forth on Schedule I attached hereto is a true and correct schedule of each
location at which Collateral
