     FIFTH AMENDMENT (this "Amendment"), dated as of April 12, 2002 among PHILIP
SERVICES CORPORATION, a Delaware corporation (the "Borrower"), CANADIAN IMPERIAL
BANK OF COMMERCE, as administrative agent for the Lenders (the "Administrative
Agent"), and the lenders from time to time parties to the Secured PIK/Term
Credit Agreement referred to below (the "Lenders"). All capitalized terms used
herein and not otherwise defined herein shall have the respective meanings
provided such terms in the Secured PIK/Term Credit Agreement referred to below.

                              W I T N E S S E T H:

     WHEREAS, the Borrower, the Lenders and Canadian Imperial Bank of Commerce,
as administrative agent (the "Administrative Agent") are parties to a Credit
Agreement, dated as of March 31, 2000 among the Borrower, the Administrative
Agent and the Lenders (as amended, modified or supplemented through, but not
including, the date hereof, the "Secured PIK/Term Credit Agreement");

     WHEREAS, the Borrower desires to obtain new mezzanine financing to be
advanced under an amended Exit Facility;

     WHEREAS, the Required Lenders hereby acknowledge that each of the Lenders
has been afforded and declined the opportunity to participate in such mezzanine
financing;

     WHEREAS, the Borrower has requested the approval of the Lenders to the
terms of such mezzanine financing and has further requested certain amendments
to the Secured PIK/Term Credit Agreement;

     WHEREAS, the Lenders have determined to grant such amendments, subject to
the terms and conditions of this Amendment.

     NOW, THEREFORE, it is agreed:

     1. Section 6.01(d)(i) of the Secured PIK/Term Credit Agreement is hereby
amended by deleting the text "$190,000,000" appearing therein and inserting the
text "$210,000,000" in lieu thereof.

     2. Section 6.13 of the Secured PIK/Term Credit Agreement is hereby amended
in its entirety as follows:

     Borrower nor a Canadian Guarantor) and

<PAGE>

     except for transactions that are either (a) in the ordinary course of such
     Obligor's business, upon fair and reasonable terms, that are fully
     disclosed to the Administrative Agent, and that are no less favorable to
     such Obligor than would be obtained in an arm's length transaction with a
     non-Affiliate, or (b) approved by the Board of Directors of the Borrower
     (with notice given to the Administrative Agent) on fair and reasonable
     terms, after full disclosure thereof to the Lenders, and that are no less
     favorable to such Obligor than would be obtained in an arm's length
     transaction with a non-Affiliate."

     therefrom, the Borrower and any of the Obligors may make Investments not
     otherwise permitted by immediately preceding clauses (a) through (i) of
     this definition of Permitted Investments in an aggregate amount not to

permanently waive any Default or Event of Default, effective as of the date of
any Default or Event of Default, that has occurred or would otherwise occur
pursuant to Section 7.02 of the Secured PIK/Term Credit Agreement as a result of
the failure of the Borrower to comply with the requirements of: (i) Section
5.02(b)(i) of the Secured PIK/Term Credit Agreement as a consequence of Borrower
being unable to provide to the Administrative Agent unqualified consolidated
financial statements for the fiscal year 2001, and (ii) Section 6.17(a) of the
Secured PIK/Term Credit Agreement as a consequence of the Borrower's failure to

Administrative Agent to execute and deliver the first amendment to the

<PAGE>

One to the Collateral Agency and Intercreditor Agreement") and (ii) the
Administrative Agent to grant the consent set forth in paragraph 8 of the
Amendment Number One to the Collateral Agency and Intercreditor Agreement. The
Required Lenders hereby acknowledge that the instructions addressed to the
Administrative Agent in this paragraph 10 are delivered in accordance with
Section 9.04 of the Secured PIK/Term Credit Agreement and that no Lender shall
have any right of action against the Administrative Agent as a result of the
Administrative Agent acting in accordance with such instructions. The Required
Lenders hereby further reaffirm the indemnification provisions contained in
inter alia Section 9.06 of the Secured PIK/Term Credit Agreement.

     11. The Borrower hereby represents and warrants that (i) no Default or
Event of Default exists on the Fifth Amendment Effective Date (as defined
below), both before and after giving effect to this Amendment (other than Events
of Default that exist immediately prior to the Fifth Amendment Effective Date as
a result of the Borrower's failure to comply with Section 5.02(b)(i) and Section
6.17(a) of the Secured PIK/Term Credit Agreement and which Events of Default are
waived pursuant to Section 9 of this Amendment) and (ii) all of the
representations and warranties contained in the Secured PIK/Term Credit
Agreement or the other Loan Documents (other than with respect to events that
have been expressly consented to in writing by the Lenders since the date on
which such representations and warranties were first made) shall be true and
correct in all material respects on and before the Fifth Amendment Effective
Date with the same effect as though such representations and warranties had been
made on and as of such date (it being understood that any representation or
warranty made as of a specific date shall be true and correct in all material
respects as of such specific date).

     12. This amendment is limited as specified and shall not constitute a
modification, amendment or waiver of any other provision of the Secured PIK/Term
Credit Agreement or any other Loan Documents.

     13. The Required Lenders hereby acknowledge that the seventh amendment to
the Exit Facility, substantially in the form of Exhibit B hereto (the "Amendment
Number Seven to Loan Agreement") is in form and substance satisfactory to the
Required Lenders.

     14. This Amendment may be executed in any number of counterparts and by the
different parties hereto on separate counterparts, each of which counterparts
when executed and delivered shall be an original, but all of which shall
together constitute one and the same instrument. A complete set of counterparts
shall be lodged with the Borrower and the Administrative Agent.

     15. THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER
SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF
NEW YORK.

     16. This Amendment shall become effective on the date (the "Fifth Amendment
Effective Date") when (i) each of the Borrower and the Required Lenders shall
have signed a copy hereof (whether the same or different copies) and, in each
case, shall have delivered (including by way of telecopier) the same to the
Administrative Agent at the Notice

(each, a "Tranche A L/C") or to purchase participations or execute indemnities
or reimbursement obligations (each such undertaking, a "Tranche A L/C
Undertaking") with respect to Tranche A Underlying Letters of Credit issued by

Underlying Letter of Credit that is to be the subject of a Tranche A L/C
Undertaking. The Issuing Lender shall have no obligation to issue a Tranche A

                           (i)      the Tranche A Letter of Credit Usage would
                                    exceed the Borrowing Base less the amount of
                                    outstanding Tranche A Advances,

                           (iii)    the Tranche A Letter of Credit Usage would
                                    exceed the Maximum Facility Amount less the
                                    sum of (A) the then extant amount of

                                    and (C) the then extant Tranche Sub-B Usage.

                  Borrowers and the Lender Group acknowledge and agree that
certain of the Existing Letters of Credit are to be the subject of Tranche A
Underlying Letters of Credit. Each Tranche A Letter of Credit (and corresponding
Tranche A Underlying Letter of Credit) shall have an expiry date no later than
10 Business Days prior to the Maturity Date (without regard to any potential
renewal term) and all such Tranche A Letters of Credit (and corresponding
Tranche A Underlying Letters of Credit) shall be in form and substance
(including the currencies in which they are to be denominated) acceptable to the
Issuing Lender (in the exercise of its Permitted Discretion). In this regard,
Borrowers acknowledge (A) that, at Issuing Lender's request, certain
arrangements have been entered into between the current Underlying Issuer and a
Canadian bank in order to satisfy Borrowers' needs to have certain of its
letters of credit issued in Canadian dollars ("Tranche A Canadian Dollar Letters
of Credit") by a Canadian bank ("Canadian Bank"), (B) that such arrangements
involve the issuance by the Issuing Lender of a Tranche A L/C Undertaking to an
Underlying Issuer which, in turn, will issue a Tranche A Underlying Letter of
Credit in favor of the Canadian Bank, (C) that such arrangements are uncommitted
facilities with terms shorter than the term of this Agreement, (D) and agree
that if such arrangements are terminated, the Issuing Lender's only obligation
with respect to securing Tranche A Canadian Dollar Letters of Credit is to use
its reasonable commercial efforts to secure one or more Canadian Banks willing
to issue Tranche A Canadian Dollar Letters of Credit supported by a Tranche A
Underlying Letter of Credit issued by the Underlying Issuer, (E) and agree that
all Tranche A L/C Disbursements payable by the Issuing Lender under any Tranche
A Letter of Credit will be payable solely in Dollars, irrespective of whether
the Tranche A Underlying Letter of Credit or any letter of credit issued based
thereupon (including any Tranche A Canadian

                                       13
<PAGE>

Dollar Letter of Credit) is payable in a currency other than Dollars, and (F)
and agree that the risk of currency fluctuations between the currency of a
particular Tranche A Underlying Letter of Credit and the Dollars payable under
the applicable Tranche A Letter of Credit is solely a risk of Borrowers and that
no currency hedging product is being provided hereunder. If Issuing Lender is
obligated to advance funds under a Tranche A Letter of Credit, Borrowers
immediately shall reimburse such Tranche A L/C Disbursement to Issuing Lender by
paying to Agent an amount equal to such Tranche A L/C Disbursement not later
than 11:00 a.m., California time, on the date that such Tranche A L/C
Disbursement is made, if Administrative Borrower shall have received written or
telephonic notice of such Tranche A L/C Disbursement prior to 10:00 a.m.,
California time, on such date, or, if such notice has not been received by
Administrative Borrower prior to such time on such date, then not later than
11:00 a.m., California time, on (i) the Business Day that Administrative
Borrower receives such notice, if such notice is received prior to 10:00 a.m.,
California time, on the date of receipt, or (ii) the Business Day immediately
following the day that Administrative Borrower receives such notice, if such
notice is not received prior to such time on the day of receipt and, in the
absence of such reimbursement, the Tranche A L/C Disbursement immediately and
automatically shall be deemed to be a Tranche A Advance hereunder and,
thereafter, shall bear interest at the rate then applicable to Base Rate Tranche
A Advances under Section 2.7. To the extent a Tranche A L/C Disbursement is
deemed to be a Tranche A Advance hereunder, Borrowers' obligation to reimburse
such Tranche A L/C Disbursement shall be discharged and replaced by the
resulting Tranche A Advance. Promptly following receipt by Agent of any payment
from Borrowers pursuant to this paragraph, Agent shall distribute such payment
to the Issuing Lender or, to the extent that Tranche A Lenders have made
payments pursuant to Section 2.2(c) to reimburse the Issuing Lender, then to
such Tranche A Lenders and the Issuing Lender as their interest may appear.

                  (b) Promptly following receipt of a notice of a Tranche A L/C
Disbursement pursuant to Section 2.2(a), each Lender with a Tranche A Commitment
shall fund its Pro Rata Share of any Tranche A Advance deemed made pursuant to
the foregoing subsection on the same terms and conditions as if Borrowers had
requested such Tranche A Advance and Agent shall promptly pay to Issuing Lender
the amounts so received by it from the Tranche A Lenders. By the issuance of a
Tranche A Letter of Credit (or an amendment to a Tranche A Letter of Credit
increasing the amount thereof) and without any further action on the part of the
Issuing Lender or the Lenders with Tranche A Commitments, the Issuing Lender
shall be deemed to have granted to each Lender with a Tranche A Commitment, and
each Lender with a Tranche A Commitment shall be deemed to have purchased, a
participation in each Tranche A Letter of Credit, in an amount equal to its Pro
Rata Share of the Risk Participation Liability of such Tranche A Letter of
Credit, and each such Tranche A Lender agrees to pay to Agent for the account of
the Issuing Lender such Tranche A Lender's Pro Rata Share of any payments made
by the Issuing Lender under such Tranche A Letter of Credit. In consideration
and in furtherance of the foregoing, each Lender with a Tranche A Commitment
hereby absolutely and unconditionally agrees to pay to Agent, for the account of
the Issuing Lender, such Tranche A Lender's Pro Rata Share of each Tranche A L/C
Disbursement made by the Issuing Lender and not reimbursed by Borrowers on the
date due as provided in paragraph (a) of this Section, or of any reimbursement
payment

                                       14
<PAGE>

required to be refunded to the Borrower for any reason. Each Lender with a
Tranche A Commitment acknowledges and agrees that its obligation to deliver to
Agent, for the account of the Issuing Lender, an amount equal to its respective
Pro Rata Share pursuant to this Section 2.2(b) shall be absolute and
unconditional and such remittance shall be made notwithstanding the occurrence
or continuation of an Event of Default or Default or the failure to satisfy any
condition set forth in Section 3 hereof. If any such Tranche A Lender fails to
make available to Agent the amount of such Tranche A Lender's Pro Rata Share of
any payments made by the Issuing Lender in respect of such Tranche A Letter of
Credit as provided in this Section, Agent (for the account of the Issuing
Lender) shall be entitled to recover such amount on demand from such Lender
together with interest thereon at the Defaulting Lender Rate until paid in full.

                  (c) Borrowers hereby agree to indemnify, save, defend, and
hold the Lender Group harmless from any loss, cost, expense, or liability, and
reasonable attorneys fees incurred by the Lender Group arising out of or in
connection with any Tranche A Letter of Credit; provided, however, that
Borrowers shall not be obligated hereunder to indemnify (i) Issuing Lender for
any loss, cost, expense, or liability that is caused by the gross negligence or
willful misconduct of the Issuing Lender or (ii) the member of the Lender Group
responsible for any loss, cost, expense or liability that is caused by such
Person's gross negligence or willful misconduct. Furthermore, the foregoing
shall not be construed to excuse the Issuing Lender or any member of the Lender
Group from liability to Borrowers to the extent of any damages suffered by
Borrowers that are caused by the gross negligence or willful misconduct of the
Issuing Lender or any member of the Lender Group. Borrowers agree to be bound by
the Underlying Issuer's regulations and interpretations of any Tranche A
Underlying Letter of Credit or by Issuing Lender's interpretations of any
Tranche A L/C issued by Issuing Lender to or for a Borrower's account, even
though this interpretation may be different from Borrowers' own, and Borrowers
understand and agree that the Lender Group shall not be liable for any error,
negligence, or mistake, whether of omission or commission, in following
Borrowers' instructions or those contained in the Tranche A Letter of Credit or
any modifications, amendments, or supplements thereto. Borrowers understand that
the Tranche A L/C Undertakings may require Issuing Lender to indemnify the
Underlying Issuer for certain costs or liabilities arising out of claims by
Borrowers against such Underlying Issuer. Borrowers hereby agree to indemnify,
save, defend, and hold the Lender Group harmless with respect to any loss, cost,
expense (including reasonable attorneys fees), or liability incurred by the
Lender Group under any Tranche A L/C Undertaking as a result of the Lender
Group's indemnification of any Underlying Issuer; provided, however, that
Borrowers shall not be obligated hereunder to indemnify (i) Issuing Lender for
any loss, cost, expense, or liability that is caused by the gross negligence or
willful misconduct of the Issuing Lender or (ii) the member of the Lender Group
responsible for any loss, cost, expense or liability that is caused by such
Person's gross negligence or willful misconduct. Furthermore, the foregoing
shall not be construed to excuse the Issuing Lender or any member of the Lender
Group from liability to Borrowers to the extent of any damages suffered by
Borrowers that are caused by the gross negligence or willful misconduct of the
Issuing Lender or any member of the Lender Group.

Issuer to deliver to the Issuing Lender all instruments, documents, and other
writings and property received by such Underlying Issuer pursuant to such
Tranche A Underlying Letter of Credit and to accept and rely upon the Issuing
Lender's instructions with respect to all matters arising in connection with
such Tranche A Underlying Letter of Credit and the related application.

                  (e) Any and all charges, commissions, fees, and costs incurred
by the Issuing Lender relating to the Tranche A Underlying Letters of Credit or
the Tranche A Canadian Dollar Letters of Credit shall be considered Lender Group
Expenses for purposes of this Agreement and immediately shall be reimbursable by
Borrowers to the Agent for the account of the Issuing Lender; provided, however,
that, solely in the case of a Tranche A Underlying Letter of Credit that is
denominated in Dollars and is not issued to support the existence or issuance of
another letter of credit (including any Tranche A Underlying Letter of Credit
issued to "backstop" an Existing Letter of Credit or a Tranche A Canadian Dollar
Letter of Credit), in place of their obligations under this clause (e), on the
date of the issuance of the applicable Tranche A Letter of Credit, Borrowers
shall pay to Agent for the account of the Issuing Lender an amount equal to
one-quarter of one percent (0.25%) of the original face amount of such Tranche A
Letter of Credit, irrespective of whether the charges, commissions, fees, and
costs are greater or lesser than such amount.

                  (f) If by reason of (i) any change in any applicable law,
treaty, rule, or regulation or any change in the interpretation or application
thereof by any Governmental Authority, or (ii) compliance by the Underlying
Issuer or the Lender Group with any direction, request, or requirement
(irrespective of whether having the force of law) of any Governmental Authority
or monetary authority including Regulation D of the Federal Reserve Board as
from time to time in effect (and any successor thereto):

                           (i)      any reserve, deposit, or similar requirement
                                    is or shall be imposed or modified in
                                    respect of any Tranche A Letters of Credit
                                    issued hereunder, or

                           (ii)     there shall be imposed on the Underlying
                                    Issuer or the Lender Group any other
                                    condition regarding any Tranche A Underlying
                                    Letter of Credit or any Tranche A Letter of
                                    Credit issued pursuant hereto;

                  and the result of the foregoing is to increase, directly or
indirectly, the cost to the Lender Group of issuing, making, guaranteeing, or
maintaining any Tranche A Letter of Credit or to reduce the amount receivable in
respect thereof by the Lender Group, then, and in any such case, Agent may, at
any time within a reasonable period after the additional cost is incurred or the
amount received is reduced, notify Administrative Borrower, and Borrowers shall
pay on demand such amounts Agent may specify to be necessary to compensate the
Lender Group for such additional cost or reduced receipt, together with interest
on such amount from the date of such demand until payment in full thereof at the
rate

                                       16
<PAGE>

then applicable to Base Rate Tranche A Advances hereunder. The determination by
Agent of any amount due pursuant to this Section, as set forth in a certificate
setting forth the calculation thereof in reasonable detail, shall, in the
absence of manifest or demonstrable error, be final and conclusive and binding
on all of the parties hereto."

         (h) The Loan Agreement is hereby amended by inserting the following new
Section 2.2A immediately following Section 2.2:

                  "2.2A    TRANCHE SUB-B LETTERS OF CREDIT.

                  (a) Subject to the terms and conditions of this Agreement,
Issuing Lender agrees to issue letters of credit for the account of Borrowers
(each, a "Tranche Sub-B L/C") or to purchase participations or execute
indemnities or reimbursement obligations (each such undertaking, a "Tranche
Sub-B L/C Undertaking") with respect to Tranche Sub-B Underlying Letters of
Credit issued by an Underlying Issuer (as of the Closing Date, such Underlying
Issuer is to be Norwest Bank Minnesota, N.A.; in the event that an Underlying
Issuer declines to issue further Tranche Sub-B Underlying Letters of Credit,
Issuing Lender agrees to use commercially reasonable efforts to obtain a
replacement Underlying Issuer; it being expressly acknowledged and agreed that
no Underlying Issuer has any obligations hereunder to Borrowers) for the account
of Borrowers. To request the issuance of a Tranche Sub-B L/C or a Tranche Sub-B
L/C Undertaking (or the amendment, renewal, or extension of an outstanding
Tranche Sub-B L/C or Tranche Sub-B L/C Undertaking), a Borrower shall hand
deliver or telecopy (or transmit by electronic communication, if arrangements
for doing so have been approved by the Issuing Lender) to the Issuing Lender and
Agent (reasonably in advance of the requested date of issuance, amendment,
renewal, or extension) a notice requesting the issuance of a Tranche Sub-B L/C
or Tranche Sub-B L/C Undertaking, or identifying the Tranche Sub-B L/C or
Tranche Sub-B L/C Undertaking to be amended, renewed, or extended, the date of
issuance, amendment, renewal, or extension, the date on which such Tranche Sub-B
L/C or Tranche Sub-B L/C Undertaking is to expire, the amount of such Tranche
Sub-B L/C or Tranche Sub-B L/C Undertaking, the name and address of the
beneficiary thereof (or of the Tranche Sub-B Underlying Letter of Credit, as
applicable), and such other information as shall be necessary to prepare, amend,
renew, or extend such Tranche Sub-B L/C or Tranche Sub-B L/C Undertaking. If
requested by the Issuing Lender, the applicable Borrower also shall be an
applicant under the application with respect to any Tranche Sub-B Underlying
Letter of Credit that is to be the subject of a Tranche Sub-B L/C Undertaking.
The Issuing Lender shall have no obligation to issue a Tranche Sub-B Letter of
Credit if any of the following would result after giving effect to the requested
Tranche Sub-B Letter of Credit:

                           (i)      the Tranche Sub-B Letter of Credit Usage
                                    would exceed the Tranche Sub-B Borrowing
                                    Base less the sum of the outstanding Tranche
                                    A Usage, Tranche B-Prime Advances and
                                    Tranche Sub-B Advances,

                                       17
<PAGE>

                           (ii)     the Tranche Sub-B Letter of Credit Usage
                                    would exceed the Maximum Tranche Sub-B
                                    Amount less the then extant amount of
                                    outstanding Tranche Sub-B Advances, or

                           (iii)    prior to the issuance of such Tranche Sub-B
                                    Letter of Credit, Agent has not received
                                    immediately available funds to be held as
                                    cash collateral to secure Icahn Lender's
                                    obligations to Agent pursuant to Section
                                    2.2A(b), in an amount equal to Icahn
                                    Lender's Pro Rata Share of the Tranche Sub-B
                                    Letter of Credit Usage attributable to such
                                    Tranche Sub-B Letter of Credit.

                  Borrowers and the Lender Group acknowledge and agree that
certain of the Existing Letters of Credit are to be the subject of Tranche Sub-B
Underlying Letters of Credit. Each Tranche Sub-B Letter of Credit (and
corresponding Tranche Sub-B Underlying Letter of Credit) shall have an expiry
date no later than 10 Business Days prior to the Maturity Date (without regard
to any potential renewal term) and all such Tranche Sub-B Letters of Credit (and
corresponding Tranche Sub-B Underlying Letters of Credit) shall be in form and
substance (including the currencies in which they are to be denominated)
acceptable to the Issuing Lender (in the exercise of its Permitted Discretion).
In this regard, Borrowers acknowledge (A) that, at Issuing Lender's request,
certain arrangements have been entered into between the current Underlying
Issuer and a Canadian bank in order to satisfy Borrowers' needs to have certain
of its letters of credit issued in Canadian dollars ("Tranche Sub-B Canadian
Dollar Letters of Credit") by a Canadian bank ("Canadian Bank"), (B) that such
arrangements involve the issuance by the Issuing Lender of a Tranche Sub-B L/C
Undertaking to an Underlying Issuer which, in turn, will issue a Tranche Sub-B
Underlying Letter of Credit in favor of the Canadian Bank, (C) that such
arrangements are uncommitted facilities with terms shorter than the term of this
Agreement, (D) and agree that if such arrangements are terminated, the Issuing
Lender's only obligation with respect to securing Tranche Sub-B Canadian Dollar
Letters of Credit is to use its reasonable commercial efforts to secure one or
more Canadian Banks willing to issue Tranche Sub-B Canadian Dollar Letters of
Credit supported by a Tranche Sub-B Underlying Letter of Credit issued by the
Underlying Issuer, (E) and agree that all Tranche Sub-B L/C Disbursements
payable by the Issuing Lender under any Tranche Sub-B Letter of Credit will be
payable solely in Dollars, irrespective of whether the Tranche Sub-B Underlying
Letter of Credit or any letter of credit issued based thereupon (including any
Tranche Sub-B Canadian Dollar Letter of Credit) is payable in a currency other
than Dollars, and (F) and agree that the risk of currency fluctuations between
the currency of a particular Tranche Sub-B Underlying Letter of Credit and the
Dollars payable under the applicable Tranche Sub-B Letter of Credit is solely a
risk of Borrowers and that no currency hedging product is being provided
hereunder. If Issuing Lender is obligated to advance funds under a Tranche Sub-B
Letter of Credit, Borrowers immediately shall reimburse such Tranche Sub-B L/C
Disbursement to Issuing Lender by paying to Agent an amount equal to such
Tranche Sub-B L/C Disbursement not later than 11:00 a.m., California time, on
the date that such Tranche Sub-B L/C Disbursement is made, if Administrative
Borrower shall have received written or telephonic notice of such Tranche Sub-B
L/C Disbursement prior to 10:00 a.m., California time, on such

                                       18
<PAGE>

date, or, if such notice has not been received by Administrative Borrower prior
to such time on such date, then not later than 11:00 a.m., California time, on
(i) the Business Day that Administrative Borrower receives such notice, if such
notice is received prior to 10:00 a.m., California time, on the date of receipt,
or (ii) the Business Day immediately following the day that Administrative
Borrower receives such notice, if such notice is not received prior to such time
on the day of receipt and, in the absence of such reimbursement, the Tranche
Sub-B L/C Disbursement immediately and automatically shall be deemed to be a
Tranche Sub-B Advance hereunder and, thereafter, shall bear interest at the rate
then applicable to Base Rate Tranche Sub-B Advances under Section 2.7. To the
extent a Tranche Sub-B L/C Disbursement is deemed to be a Tranche Sub-B Advance
hereunder, Borrowers' obligation to reimburse such Tranche Sub-B L/C
Disbursement shall be discharged and replaced by the resulting Tranche Sub-B
Advance. Promptly following receipt by Agent of any payment from Borrowers
pursuant to this paragraph, Agent shall distribute such payment to the Issuing
Lender or, to the extent that Tranche Sub-B Lenders have made payments pursuant
to Section 2.2A(c) to reimburse the Issuing Lender, then to such Tranche Sub-B
Lenders and the Issuing Lender as their interest may appear.

                  (b) Promptly following receipt of a notice of a Tranche Sub-B
L/C Disbursement pursuant to Section 2.2A(a), each Lender with a Tranche Sub-B
Commitment shall fund its Pro Rata Share of any Tranche Sub-B Advance deemed
made pursuant to the foregoing subsection on the same terms and conditions as if
Borrowers had requested such Tranche Sub-B Advance and Agent shall promptly pay
to Issuing Lender the amounts so received by it from the Tranche Sub-B Lenders;
provided, however, that Icahn Lender's payment obligations pursuant to this
Section 2.2A(b) shall be satisfied first from any cash collateral held by Agent
for Icahn Lender pursuant to Section 2.2A(g) hereof. By the issuance of a
Tranche Sub-B Letter of Credit (or an amendment to a Tranche Sub-B Letter of
Credit increasing the amount thereof) and without any further action on the part
of the Issuing Lender or the Lenders with Tranche Sub-B Commitments, the Issuing
Lender shall be deemed to have granted to each Lender with a Tranche Sub-B
Commitment, and each Lender with a Tranche Sub-B Commitment shall be deemed to
have purchased, a participation in each Tranche Sub-B Letter of Credit, in an
amount equal to its Pro Rata Share of the Risk Participation Liability of such
Tranche Sub-B Letter of Credit, and each such Tranche Sub-B Lender agrees to pay
to Agent for the account of the Issuing Lender such Tranche Sub-B Lender's Pro
Rata Share of any payments made by the Issuing Lender under such Tranche Sub-B
Letter of Credit. In consideration and in furtherance of the foregoing, each
Lender with a Tranche Sub-B Commitment hereby absolutely and unconditionally
agrees to pay to Agent, for the account of the Issuing Lender, such Tranche
Sub-B Lender's Pro Rata Share of each Tranche Sub-B L/C Disbursement made by the
Issuing Lender and not reimbursed by Borrowers on the date due as provided in
paragraph (a) of this Section, or of any reimbursement payment required to be
refunded to the Borrower for any reason. Each Lender with a Tranche Sub-B
Commitment acknowledges and agrees that its obligation to deliver to Agent, for
the account of the Issuing Lender, an amount equal to its respective Pro Rata
Share pursuant to this Section 2.2A(b) shall be absolute and unconditional and
such remittance shall be made notwithstanding the occurrence or continuation of
an Event of Default or Default or the failure to satisfy any condition set forth

                                       19
<PAGE>

in Section 3 hereof. If any such Tranche Sub-B Lender fails to make available to
Agent the amount of such Tranche Sub-B Lender's Pro Rata Share of any payments
made by the Issuing Lender in respect of such Tranche Sub-B Letter of Credit as
provided in this Section, Agent (for the account of the Issuing Lender) shall be
entitled to recover such amount on demand from such Lender together with
interest thereon at the Defaulting Lender Rate until paid in full.

                  (c) Borrowers hereby agree to indemnify, save, defend, and
hold the Lender Group harmless from any loss, cost, expense, or liability, and
reasonable attorneys fees incurred by the Lender Group arising out of or in
connection with any Tranche Sub-B Letter of Credit; provided, however, that
Borrowers shall not be obligated hereunder to indemnify (i) Issuing Lender for
any loss, cost, expense, or liability that is caused by the gross negligence or
willful misconduct of the Issuing Lender or (ii) the member of the Lender Group
responsible for any loss, cost, expense or liability that is caused by such
Person's gross negligence or willful misconduct. Furthermore, the foregoing
shall not be construed to excuse the Issuing Lender or any member of the Lender
Group from liability to Borrowers to the extent of any damages suffered by
Borrowers that are caused by the gross negligence or willful misconduct of the
Issuing Lender or any member of the Lender Group. Borrowers agree to be bound by
the Underlying Issuer's regulations and interpretations of any Tranche Sub-B
Underlying Letter of Credit or by Issuing Lender's interpretations of any
Tranche Sub-B L/C issued by Issuing Lender to or for a Borrower's account, even
though this interpretation may be different from Borrowers' own, and Borrowers
understand and agree that the Lender Group shall not be liable for any error,
negligence, or mistake, whether of omission or commission, in following
Borrowers' instructions or those contained in the Tranche Sub-B Letter of Credit
or any modifications, amendments, or supplements thereto. Borrowers understand
that the Tranche Sub-B L/C Undertakings may require Issuing Lender to indemnify
the Underlying Issuer for certain costs or liabilities arising out of claims by
Borrowers against such Underlying Issuer. Borrowers hereby agree to indemnify,
save, defend, and hold the Lender Group harmless with respect to any loss, cost,
expense (including reasonable attorneys fees), or liability incurred by the
Lender Group under any Tranche Sub-B L/C Undertaking as a result of the Lender
Group's indemnification of any Underlying Issuer; provided, however, that
Borrowers shall not be obligated hereunder to indemnify (i) Issuing Lender for
any loss, cost, expense, or liability that is caused by the gross negligence or
willful misconduct of the Issuing Lender or (ii) the member of the Lender Group
responsible for any loss, cost, expense or liability that is caused by such
Person's gross negligence or willful misconduct. Furthermore, the foregoing
shall not be construed to excuse the Issuing Lender or any member of the Lender
Group from liability to Borrowers to the extent of any damages suffered by
Borrowers that are caused by the gross negligence or willful misconduct of the
Issuing Lender or any member of the Lender Group.

                  (d) Borrower hereby authorizes and directs any Underlying
Issuer to deliver to the Issuing Lender all instruments, documents, and other
writings and property received by such Underlying Issuer pursuant to such
Tranche Sub-B Underlying Letter of Credit and to accept and rely upon the
Issuing Lender's instructions with respect to all

                                       20
<PAGE>

matters arising in connection with such Tranche Sub-B Underlying Letter of
Credit and the related application.

                  (e) Any and all charges, commissions, fees, and costs incurred
by the Issuing Lender relating to the Tranche Sub-B Underlying Letters of Credit
or the Tranche Sub-B Canadian Dollar Letters of Credit shall be considered
Lender Group Expenses for purposes of this Agreement and immediately shall be
reimbursable by Borrowers to the Agent for the account of the Issuing Lender;
provided, however, that, solely in the case of a Tranche Sub-B Underlying Letter
of Credit that is denominated in Dollars and is not issued to support the
existence or issuance of another letter of credit (including any Tranche Sub-B
Underlying Letter of Credit issued to "backstop" an Existing Letter of Credit or
a Tranche Sub-B Canadian Dollar Letter of Credit), in place of their obligations
under this clause (e), on the date of the issuance of the applicable Tranche
Sub-B Letter of Credit, Borrowers shall pay to Agent for the account of the
Issuing Lender an amount equal to one-quarter of one percent (0.25%) of the
original face amount of such Tranche Sub-B Letter of Credit, irrespective of
whether the charges, commissions, fees, and costs are greater or lesser than
such amount.

                  (f) If by reason of (i) any change in any applicable law,
treaty, rule, or regulation or any change in the interpretation or application
thereof by any Governmental Authority, or (ii) compliance by the Underlying
Issuer or the Lender Group with any direction, request, or requirement
(irrespective of whether having the force of law) of any Governmental Authority
or monetary authority including Regulation D of the Federal Reserve Board as
from time to time in effect (and any successor thereto):

                           (i)      any reserve, deposit, or similar requirement
                                    is or shall be imposed or modified in
                                    respect of any Tranche Sub-B Letters of
                                    Credit issued hereunder, or

                           (ii)     there shall be imposed on the Underlying
                                    Issuer or the Lender Group any other
                                    condition regarding any Tranche Sub-B
                                    Underlying Letter of Credit or any Tranche
                                    Sub-B Letter of Credit issued pursuant
                                    hereto;

                  and the result of the foregoing is to increase, directly or
indirectly, the cost to the Lender Group of issuing, making, guaranteeing, or
maintaining any Tranche Sub-B Letter of Credit or to reduce the amount
receivable in respect thereof by the Lender Group, then, and in any such case,
Agent may, at any time within a reasonable period after the additional cost is
incurred or the amount received is reduced, notify Administrative Borrower, and
Borrowers shall pay on demand such amounts Agent may specify to be necessary to
compensate the Lender Group for such additional cost or reduced receipt,
together with interest on such amount from the date of such demand until payment
in full thereof at the rate then applicable to Base Rate Tranche Sub-B Advances
hereunder. The determination by Agent of any amount due pursuant to this
Section, as set forth in a certificate setting forth the calculation thereof in
reasonable detail, shall, in the absence of

                                       21
<PAGE>

manifest or demonstrable error, be final and conclusive and binding on all of
the parties hereto.

                  (g) Icahn Lender hereby agrees that, no later than one
Business Day prior to the issuance of each Tranche Sub-B Letter of Credit, Icahn
Lender will promptly pay to Agent in immediately available funds, an amount
equal to Icahn Lender's Pro Rata Share of the Tranche Sub-B Letter of Credit
Usage attributable to such Tranche Sub-B Letter of Credit, to be held as cash
collateral for Icahn Lender's obligations to Agent pursuant to Section 2.2A(b)
hereof, which cash collateral, to the extent not applied in satisfaction of
Icahn Lender's obligations to Agent pursuant to Section 2.2A(b) hereof, shall be
returned to promptly upon, and to the extent of, Icahn Lender's Pro Rata Share
of the reduction of the Tranche Sub-B Letter of Credit Usage."

         (i) Section 2.3 of the Loan Agreement is amended and restated in its
entirety as follows:

                  "2.3     TRANCHE B-PRIME ADVANCES.

                           (a) Subject to the terms and conditions of this
Agreement, and during the term of this Agreement, each Lender with a Tranche
B-Prime Commitment agrees to make advances ("Tranche B-Prime Advances") to
Borrowers in an amount at any one time outstanding not to exceed such Lender's
Pro Rata Share of an amount equal to the lower of (i) the Maximum Tranche
B-Prime Amount, or (ii) the Borrowing Base less the Tranche A Usage.

                           (b) Anything to the contrary in this Section 2.3
notwithstanding, Borrowers shall not have the right to require Lenders with
Tranche B-Prime Commitments to make Tranche B-Prime Advances to Borrowers unless
the Tranche A Usage exceeds the difference between the Maximum Tranche A Amount
and $10,000,000.

                           (c) The Lenders with Tranche B-Prime Commitments
shall have no obligation to make additional Tranche B-Prime Advances hereunder
to the extent such additional Tranche B-Prime Advances would cause the sum of
the Tranche A Usage, the Tranche B-Prime Usage and the Tranche Sub-B Usage to
exceed the Maximum Facility Amount.

                           (d) Amounts borrowed pursuant to this Section may be
repaid and, subject to the terms and conditions of this Agreement, reborrowed at
any time during the term of this Agreement; provided, however, that, if and so
long as any Tranche A Advances are outstanding, no Tranche B-Prime Advance shall
be repaid unless, after giving effect to such repayment, Tranche A Advance
Availability is greater than $7,500,000."

         (j) The Loan Agreement is hereby amended by inserting the following new
Section 2.3A immediately following Section 2.3:

                  "2.3A    TRANCHE SUB-B ADVANCES.

                                       22
<PAGE>

                           (a) Subject to the terms and conditions of this
Agreement, and during the term of this Agreement, each Lender with a Tranche
Sub-B Commitment agrees to make advances ("Tranche Sub-B Advances") to Borrowers
in an amount at any one time outstanding not to exceed such Lender's Pro Rata
Share of an amount equal to the lower of (i) the Maximum Tranche Sub-B Amount
less the then extant Tranche Sub-B Letter of Credit Usage, or (ii) the Tranche
Sub-B Borrowing Base less the sum of (A) the Tranche A Usage, (B) the Tranche
B-Prime Usage, and (C) the then extant Tranche Sub-B Letter of Credit Usage.

                           (b) Anything to the contrary in this Section 2.3A
notwithstanding, Agent shall have the right to establish reserves in such
amounts, and with respect to such matters, as Agent in its Permitted Discretion
shall deem necessary or appropriate, against the Tranche Sub-B Borrowing Base,
including reserves with respect to (i) sums that Borrowers are required to pay
(such as taxes, assessments, insurance premiums, or, in the case of leased
assets, rents or other amounts payable under such leases) and have failed to pay
under any Section of this Agreement or any other Loan Document, and (ii) amounts
owing by Borrowers to any Person to the extent secured by a Lien (other than any
existing Permitted Lien set forth on Schedule P-3 which is specifically
identified thereon as entitled to have priority over Collateral Agent's Liens)
on, or trust over, any of the Collateral, which Lien or trust, in the Permitted
Discretion of Agent, would be likely to have a priority superior to the Liens of
Agent, for the benefit of the Lender Group (such as landlord liens, ad valorem
taxes, property taxes, or sales taxes where given priority under applicable law)
in and to such item of the Collateral.

                           (c) Anything to the contrary in this Section 2.3A
notwithstanding, Borrowers shall not have the right to require Lenders with
Tranche Sub-B Commitments to make Tranche Sub-B Advances to Borrowers unless (i)
the Tranche A Usage exceeds the difference between Maximum Tranche A Amount and
$10,000,000, and (ii) Tranche B-Prime Availability is less than $10,000,000.

                           (d) The Lenders with Tranche Sub-B Commitments shall
have no obligation to make additional Tranche Sub-B Advances hereunder to the
extent such additional Tranche Sub-B Advances would cause the sum of the Tranche
A Usage, the Tranche B-Prime Usage and the Tranche Sub-B Usage to exceed the
Maximum Facility Amount.

                           (e) Amounts borrowed pursuant to this Section may be
repaid and, subject to the terms and conditions of this Agreement, reborrowed at
any time during the term of this Agreement; provided, however, that, if and so
long as any Tranche A Advances are outstanding, no Tranche Sub-B Advance shall
be repaid unless, after giving effect to such repayment, Tranche A Advance
Availability is greater than $7,500,000; provided, further, that, if and so long
as any Tranche B-Prime Advances are outstanding, no Tranche Sub-B Advance shall
be repaid unless, after giving effect to such repayment, Tranche B-Prime
Availability is greater than $7,500,000."

         (k) Section 2.4(a) of the Loan Agreement is hereby amended and restated
in its entirety as follows:

                  "(a) PROCEDURE FOR BORROWING. Each Borrowing shall be made by
an irrevocable written request by an Authorized Person delivered to Agent (which
notice must be received by Agent no later than 10:00 a.m. (California time) on
(y) the Business Day prior to the date that is the requested Funding Date in the
case of a request for a Tranche A Advance, and (z) the 3rd Business Day prior to
the date that is the requested Funding Date in the case of a request for a
Tranche B-Prime Advance or a Tranche Sub-B Advance) specifying (i) the amount of
such Borrowing, and (ii) the requested Funding Date, which shall be a Business
Day; provided, however, that in the case of a request for Swing Loan in an
amount of $10,000,000, or less, such notice will be timely received if it is
received by Agent no later than 10:00 a.m. (California time) on the Business Day
that is the requested Funding Date) specifying (i) the amount of such Borrowing,
and (ii) the requested Funding Date, which shall be a Business Day. At Agent's
election, in lieu of delivering the above-described written request, any
Authorized Person may give Agent telephonic notice of such request by the
required time, with such telephonic notice to be confirmed in writing within 24
hours of the giving of such notice."

         (l) Section 2.4(c)(i) of the Loan Agreement is hereby amended and
restated in its entirety as follows:

                  "(i) In the event that Agent shall elect to have the terms of
this Section 2.4(c) apply to a requested Borrowing as described in Section
2.4(b), then promptly after receipt of a request for a Borrowing pursuant to
Section 2.4(a), Agent shall notify the Lenders, not later than 1:00 p.m.
(California time) on (A) the Business Day immediately preceding the Funding Date
applicable thereto in the case of a request for a Tranche A Advance, and (B) the
3rd Business Day immediately preceding the Funding Date applicable thereto in
the case of a request for a Tranche B-Prime Advance or a Tranche Sub-B Advance,
in each case by telecopy, telephone, or other similar form of transmission, of
the requested Borrowing. Each Lender shall make the amount of such Lender's Pro
Rata Share of the requested Borrowing available to Agent in immediately
available funds, to such account of Agent as Agent may designate, not later than
10:00 a.m. (California time) on (y) the Funding Date applicable thereto in the
case of a request for a Tranche A Advance, and (z) the Business Day immediately
preceding the Funding Date applicable thereto in the case of a request for a
Tranche B-Prime Advance or a Tranche Sub-B Advance. After Agent's receipt of the
proceeds of such Advances, upon satisfaction of the applicable conditions
precedent set forth in Section 3 hereof, Agent shall make the proceeds of such
Advances available to Borrowers on the applicable Funding Date by transferring
same day funds equal to the proceeds of such Advances received by Agent to
Administrative Borrower's Designated Account; provided, however, that, subject
to the provisions of Section 2.4(i), Agent shall not request any Lender to make,
and no Lender shall have the obligation to make, any Advance if Agent shall have
received written notice from any Lender, or otherwise has actual knowledge, that
(1) one or more of the applicable conditions precedent set forth in Section 3
will not be satisfied on the requested Funding Date for the applicable Borrowing
unless such

                                       24
<PAGE>

condition has been waived in accordance with Section 15.1, or (2) the requested
Borrowing would exceed the Tranche A Advance Availability, Tranche B-Prime
Availability or Tranche Sub-B Advance Availability, as applicable, on such
Funding Date."

         (m) The first sentence of Section 2.4(c)(ii) of the Loan Agreement is
hereby amended and restated in its entirety as follows:

                  "Unless Agent receives notice from a Lender on or prior to the
Closing Date or, with respect to any Borrowing after the Closing Date, at least
1 Business Day prior to the date of such Borrowing, that such Lender will not
make available as and when required hereunder to Agent for the account of
Borrowers the amount of that Lender's Pro Rata Share of the Borrowing, Agent may
assume that each Lender has made or will make such amount available to Agent in
immediately available funds when due pursuant to Section 2.4(c)(i) hereof and
Agent may (but shall not be so required), in reliance upon such assumption, make
available to Borrowers on such date a corresponding amount."

         (n) Section 2.4(i) of the Loan Agreement is hereby amended and restated
in its entirety as follows:

                  "(i) Optional Overadvances. Any contrary provision of this
Agreement notwithstanding, if the condition for borrowing under Section 3.3(d)
cannot be fulfilled, the Lenders nonetheless hereby authorize Agent or Swing
Lender, as applicable, and Agent or Swing Lender, as applicable, may, but is not
obligated to, knowingly and intentionally continue to make Tranche A Advances
(including Swing Loans) to Borrowers, such failure of condition notwithstanding,
so long as, at the time any such Tranche A Advance is made, (i) the outstanding
Tranche A Usage does not exceed the Borrowing Base by more than $10,000,000,
(ii) after giving effect to any such Overadvance, the then extant amount of
Tranche A Advances does not exceed $50,000,000, and (iii) after giving effect to
any such Overadvance, the aggregate amount of outstanding optional Overadvances
made by Agent and Swing Lenders to Borrowers pursuant to this Section 2.4(i)
shall not exceed $10,000,000. The foregoing provisions are for the sole and
exclusive benefit of Agent, Swing Lenders, and the Lenders and are not intended
to benefit Borrowers in any way. The Advances and Swing Loans, as applicable,
that are made pursuant to this Section 2.4(i) shall be subject to the same terms
and conditions as any other Advance or Swing Loan, as applicable, except that
the rate of interest applicable thereto shall be the rates set forth in Section
2.7(c) hereof without regard to the presence or absence of a Default or Event of
Default."

         (o) Section 2.5(b)(i) of the Loan Agreement is hereby amended and

of the Advances to which such payments relate held by each Lender) and payments

         (p) Section 2.5(c) of the Loan Agreement is hereby amended and restated
in its entirety as follows:

                  "(c) ASSET DISPOSITION PROCEEDS; REDUCTION OF COMMITMENTS.
Promptly upon receipt by Agent of any proceeds from Collateral Agent, whether on
account of Permitted Dispositions, condemnation proceeds, casualty proceeds, or
otherwise, (i) subject to the last sentence of this subsection, Agent shall
apply such proceeds in accordance with Section 2.5(b) above, (ii) if and to the
extent that Section 5.a. of the Collateral Agency and Intercreditor Agreement
requires that the payment of proceeds is to be accompanied by a reduction of the
Tranche Sub-B Commitments, then such reduction shall be applied solely to the
Tranche Sub-B Commitments, (iii) if and to the extent that the Collateral Agency
and Intercreditor Agreement (other than pursuant to Section 5.a. of the
Collateral Agency and Intercreditor Agreement) requires that the payment of
proceeds is to be accompanied by a reduction of the Commitments, then such
reduction shall be applied (x) first, to the Tranche A Commitments, such
reduction to be applied ratably amongst each of the Lenders with Tranche A
Commitments, (y) second, to the Tranche B-Prime Commitments, such reduction to
be applied ratably amongst each of the Lenders with Tranche B-Prime Commitments,
and (z) third, to the Tranche Sub-B Commitments, such reduction to be applied
ratably amongst each of the Lenders with Tranche Sub-B Commitments, and (iv) if
and to the extent that the Collateral Agency and Intercreditor Agreement
provides that the payment of proceeds is to be accompanied by a reduction of the
Commitments only to the extent elected by the Lenders, then such election shall
be made and such reduction shall be applied (x) first, to the Tranche A
Commitments, to the extent agreed to by Tranche A Lenders whose Pro Rata Shares
aggregate 51% of the Tranche A Commitments, such reduction to be applied ratably
amongst each of the Lenders with Tranche A Commitments, (y) second, if and to
the extent that the Tranche A Lenders affirmatively decide that less than all of
the available reductions should reduce the Tranche A Commitments, to the extent
agreed to by Tranche B-Prime Lenders whose Pro Rata Shares aggregate 51% of the
Tranche B-Prime Commitments, to the Tranche B-Prime Commitments, such remaining
available reduction to be applied ratably amongst each of the Lenders with
Tranche B-Prime Commitments, and (z) third, if and to the extent that the
Tranche B-Prime Lenders affirmatively decide that less than all of the available
reductions should reduce the Tranche B-Prime Commitments, to the extent agreed
to by Tranche Sub-B Lenders whose Pro Rata Shares aggregate 51% of the Tranche
Sub-B Commitments, to the Tranche Sub-B Commitments, such remaining available
reduction to be

applied ratably amongst each of the Lenders with Tranche Sub-B Commitments. In
each instance when the Tranche A Commitments are reduced, (i) the amount of the
Maximum Tranche A Amount and the Maximum Facility Amount shall be reduced on a
Dollar-for-Dollar basis, and (ii) the amount set forth in Section 2.1(a)(iii)
and the amount set forth in item (iii) of the definition of Tranche A Advance
Availability shall be reduced proportionately with the reduction of the Tranche
A Commitments. In each instance when the Tranche B-Prime Commitments are
reduced, the amount of the Maximum Tranche B-Prime Amount and the Maximum
Facility Amount shall be reduced on a Dollar-for-Dollar basis. In each instance
when the Tranche Sub-B Commitments are reduced, the amount of the Maximum
Tranche Sub-B Amount and the Maximum Facility Amount shall be reduced on a
Dollar-for-Dollar basis. In any instance when the Tranche A Commitments are
reduced, if, after giving effect to such reduction, the amount of the then
extant Tranche A Letter of Credit Usage exceeds the amount of the Tranche A
Commitments, then Agent shall retain from the proceeds remitted to it from the
Collateral Agent an amount equal to 105% of such excess and such amount retained
shall be held by Agent, for the ratable benefit of Agent and those Lenders
having a Tranche A Commitment, as cash collateral until the outstanding Tranche
A Letters of Credit are paid in full, with any balance being applied in
accordance with Section 2.5(b) above. In any instance when the Tranche Sub-B
Commitments are reduced, if, after giving effect to such reduction, the amount
of the then extant Tranche Sub-B Letter of Credit Usage exceeds the amount of
the Tranche Sub-B Commitments, then Agent shall retain from the proceeds
remitted to it from the Collateral Agent an amount equal to 105% of such excess
and such amount retained shall be held by Agent, for the ratable benefit of
Agent and those Lenders having a Tranche Sub-B Commitment, as cash collateral
until the outstanding Tranche Sub-B Letters of Credit are paid in full, with any
balance being applied in accordance with Section 2.5(b) above."

         (q) Section 2.6 of the Loan Agreement is hereby amended and restated in
its entirety as follows:

                  "2.6 OVERADVANCES. If, at any time or for any reason, the
amount of Obligations owed by Borrowers to the Lender Group pursuant to Sections

limitations set forth in Sections 2.1, 2.2, 2.2A, 2.3 or 2.3A, (an
"Overadvance"), except with respect to optional Overadvances provided for in
Section 2.4(i), Borrowers immediately shall pay to Agent, in cash, the amount of
such excess, which amount shall be used by Agent to reduce the Obligations in
accordance with the priorities set forth in Section 2.5(b), with any remaining
amount (to the extent that Agent is not holding (and will not thereafter hold as
a result of the payments required by this Section 2.6) cash collateral in excess
of 105% of the maximum amount of Issuing Lender's obligations under outstanding

the Obligations with respect to the Tranche A Letters of Credit until paid in
full, (the "Tranche A Collateral Amount"), with any remaining amount being held
by Agent, for the ratable benefit of Agent and those Lenders having a Tranche

"Collateral Amount"); provided, however, that if, at any time and for any
reason, Borrowers' Combined Availability is greater than zero, Agent shall
immediately release the Collateral Amount to the extent of such Combined
Availability (with amounts being released first from the Tranche Sub-B
Collateral Amount until released in full, and with any remaining amount being
released from the Tranche A Collateral Amount), and apply such amount in
accordance with the priorities set forth in Section 2.5(b). In addition, each
Borrower, jointly and severally, hereby promises to pay the Obligations
(including principal, interest, fees, costs, and expenses) in Dollars in full to
Agent for the account of the Lender Group as and when due and payable under the
terms of this Agreement and the other Loan Documents."

Balance thereof as follows (i) if a LIBOR Rate Advance, at a per annum rate
equal to the LIBOR Rate plus the LIBOR Margin, (ii) if a Tranche Sub-B Advance,
at a per annum rate equal to the greater of (A) 11.50%, and (B) the Base Rate
plus 5.0 percentage points, and (iii) otherwise, at a per annum rate equal to
the Base Rate plus the Applicable Base Rate Margin."

         (s) Section 2.7(b) of the Loan Agreement is hereby amended and restated
in its entirety as follows:

                  "(b) LETTER OF CREDIT FEE. (i) Borrowers shall pay Agent (for
the ratable benefit of the Lenders with a Tranche A Commitment based upon their
Pro Rata Share of the Tranche A Commitment), a Tranche A Letter of Credit fee
(in addition to the charges, commissions, fees, and costs set forth in Section
2.2(e)) which shall accrue at a rate equal to 2.75% per annum times the average
daily aggregate undrawn amount of all outstanding Tranche A Letters of Credit
during the month preceding the date such Tranche A Letter of Credit fee is due
and payable in accordance with Section 2.7(d) hereof, and (ii) Borrowers shall
pay Agent (for the ratable benefit of the Lenders with a Tranche Sub-B
Commitment based upon their Pro Rata Share of the Tranche Sub-B Commitment), a

6. CONSTRUCTION. THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE
AND TO BE PERFORMED IN THE STATE OF NEW YORK.

7. ENTIRE AMENDMENT; EFFECT OF AMENDMENT. This Amendment, and terms and
provisions hereof, constitute the entire agreement among the parties pertaining
to the subject matter hereof and supersedes any and all prior or contemporaneous
amendments relating to the subject matter hereof. Except for the amendments to
the Loan Agreement expressly set forth in Section 2 hereof, the Loan Agreement
and other Loan Documents shall remain unchanged and in full force and effect.
The execution, delivery, and performance of this Amendment shall not operate as
a waiver of or, except as expressly set forth herein, as an amendment of, any
right, power, or remedy of the Lender Group as in effect prior to the date
hereof. The amendments and other agreements set forth herein are limited to the
specifics hereof, shall not apply with respect to any facts or occurrences other
than those on which the same are based, shall not excuse future non-compliance
with the Loan Agreement, and shall not operate as a consent to any further or
other matter, under the Loan Documents. To the extent any terms or provisions of
this Amendment conflict with those of the Loan Agreement or other Loan

Amendment is a Loan Document. Any failure by Borrowers to comply with any of the
covenants or other agreements set forth herein shall constitute an immediate
Event of Default.

number of counterparts, all of which taken together shall constitute one and the
same instrument and any of the parties hereto may execute this Amendment by

Amendment by telefacsimile shall be equally as effective as delivery of an
original executed counterpart of this Amendment. Any party delivering an
executed counterpart of this Amendment by telefacsimile also shall deliver an
original executed counterpart of this Amendment, but the failure to deliver an
original executed counterpart shall not affect the validity, enforceability, and
binding effect of this Amendment.

Loan Agreement to "this Agreement", "hereunder", "herein", "hereof" or words of
