certain  financial  institutions from time to time party thereto (the "Lenders")
(as the same may be amended,  restated,  supplemented or otherwise modified from

guarantee  the  Indebtedness  under the Second Lien Term Loan  Agreement and the
other Loan Documents;

     NOW,  THEREFORE,  in consideration of the foregoing premises and other good
and  valuable  consideration,  the receipt and  sufficiency  of which are hereby
acknowledged, the parties hereto agree as follows:

<PAGE>

     Section 1.  Representations,  Warranties and Covenants.  In order to induce
the Administrative Agent and the Lenders to enter into the Second Lien Term Loan
Agreement and to make the Loans and the other  financial  accommodations  to the
Borrowers, each of the Guarantors represents and warrants to each Lender and the
Administrative  Agent as of the date of this  Agreement,  giving  effect  to the
consummation  of the  transactions  contemplated  by the Loan  Documents  on the
Effective  Date,  and thereafter on each date as required by Section 6.02 of the
Second Lien Term Loan Agreement that:

     (a) It (i) is a corporation,  partnership or limited liability company duly
incorporated  or  organized,  as the case may be,  validly  existing and in good
standing under the laws of its  jurisdiction of  incorporation  or organization,
(ii) is  duly  qualified  to do  business  as a  foreign  entity  and is in good
standing under the laws of each jurisdiction where the business by it makes such
qualification  necessary,   except  where  the  failure  to  qualify  could  not
reasonably  be expected  to have a Material  Adverse  Effect,  and (iii) has all
requisite  corporate,   partnership  or  limited  liability  company  power  and
authority,  as the case may be, to own, operate and encumber its property and to
conduct its business in each jurisdiction in which its business is conducted.

     (b)  It  has  the  requisite   corporate,   limited  liability  company  or
partnership,  as applicable,  power and authority and legal right to execute and
deliver this Guaranty and to perform its  obligations  hereunder.  The execution
and  delivery  by it of  this  Guaranty  and  the  performance  by  each  of its
obligations hereunder have been duly authorized by proper proceedings,  and this
Guaranty  constitutes a legal,  valid and binding  obligation of each Guarantor,
enforceable  against such  Guarantor,  in accordance  with its terms,  except as
enforceability  may  be  limited  by  (i)  bankruptcy,   insolvency,  fraudulent
conveyances,  reorganization  or  similar  laws  relating  to or  affecting  the
enforcement of creditors'  rights generally,  (ii) general equitable  principles
(whether considered in a proceeding in equity or at law), and (iii) requirements
of reasonableness, good faith and fair dealing.

     (c) Neither the  execution  and  delivery by it of this  Guaranty,  nor the
consummation by it of the transactions herein contemplated, nor compliance by it
with the terms and  provisions  hereof,  will (i)  conflict  with the charter or
other organizational documents of such Guarantor,  (ii) conflict with, result in
a breach of or  constitute  (with or without  notice or lapse of time or both) a
default under any law, rule,  regulation,  order,  writ,  judgment,  injunction,
decree or award  (including,  without  limitation,  any  environmental  property
transfer laws or regulations)  applicable to such Guarantor or any provisions of
any  indenture,  instrument or agreement to which such  Guarantor is party or is
subject or which it or its property is bound or affected, or require termination
of any such  indenture,  instrument  or agreement,  except where such  conflict,
breach or default could not  reasonably  be expected to have a Material  Adverse
Effect,  (iii)  result in or require  the  creation  or  imposition  of any Lien
whatsoever  upon any of the  property  or assets of such  Guarantor,  other than
Liens permitted or created by the Loan  Documents,  or (iv) require any approval
of such  Guarantor's  board of directors or shareholders  or unitholders  except
such as have been  obtained.  Except as set forth in Section  7.03 of the Second
Lien  Term  Loan  Agreement  the  execution,  delivery  and  performance  by the
Guarantors of each of the Loan  Documents to which such  Guarantor is a party do
not and will not  require any  registration  with,  consent or  approval  of, or
notice to, or other action to, with or by any governmental authority,  including
under any environmental  property transfer laws or regulations,  except filings,
consents or notices which have been made.

     (d) It has no Debt  other than Debt  permitted  under  Section  9.02 of the
Second Lien Term Loan Agreement.

     In addition to the  foregoing,  each of the Guarantors  covenants  that, so
long as any Lender has any  Commitment  outstanding  under the Second  Lien Term
Loan  Agreement or any amount  payable under the Second Lien Term Loan Agreement
or any other Indebtedness shall remain unpaid, it will, and, if necessary,  will
enable the Borrowers to, fully comply with those covenants and agreements of the
Borrowers  applicable to such  Guarantor set forth in such Second Lien Term Loan
Agreement.

     Section 2. The  Guaranty.  Each of the  Guarantors  hereby  unconditionally
guarantees,  jointly  and  severally  with the  other  Guarantors,  the full and
punctual  payment and  performance  when due (whether at stated  maturity,  upon
acceleration or otherwise) of the Indebtedness,  including,  without limitation,
(i) the principal of and interest on each Loan made to each Borrower pursuant to
the Second  Lien Term Loan  Agreement,  (ii) all other  amounts  payable by each
Borrower under the Second Lien Term Loan Agreement and the other Loan Documents,
including,  without limitation, all obligations under Swap Agreements, and (iii)
the punctual and faithful performance,  keeping,  observance, and fulfillment by
each Borrower of all of the agreements,  conditions,  covenants, and obligations
of such Borrower  contained in the Loan  Documents  (all of the foregoing  being
referred to collectively as the "Guaranteed Indebtedness"). Upon (x) the failure
by any Borrower, or any of its Affiliates,  as applicable, to pay punctually any
such amount or perform such obligation,  and (y) such failure  continuing beyond
any applicable  grace or notice and cure period,  each of the Guarantors  agrees
that it shall  forthwith on demand pay such amount or perform such obligation at
the place and in the manner  specified in the Second Lien Term Loan Agreement or
the relevant Loan Document,  as the case may be. Each of the  Guarantors  hereby
agrees that this Guaranty is an absolute, irrevocable and unconditional guaranty
of  payment  and is  not a  guaranty  of  collection.  This  Guaranty  shall  be
subordinated  in right of payment to the Guaranty  granted by the  Guarantors to
the Administrative Agent pursuant to the Senior Credit Facility and any right to
payment  under this  Guaranty  shall at all times be subject to the terms of the
Intercreditor Agreement.

     Section 3. Guaranty Unconditional.  Except as otherwise provided in Section
2 of this Agreement,  the obligations of each of the Guarantors  hereunder shall
be  unconditional  and absolute  and,  without  limiting the  generality  of the
foregoing, shall not be released, discharged or otherwise affected by:

          (i) any extension, renewal, settlement, indulgence, compromise, waiver
     or release of or with respect to the  Guaranteed  Indebtedness  or any part
     thereof  or  any  agreement  relating  thereto,  or  with  respect  to  any
     obligation of any other  guarantor of any of the  Guaranteed  Indebtedness,
     whether (in any such case) by operation of law or otherwise, or any failure
     or  omission  to enforce  any right,  power or remedy  with  respect to the
     Guaranteed  Indebtedness  or any part  thereof  or any  agreement  relating
     thereto, or with respect to any obligation of any other guarantor of any of
     the  Guaranteed  Indebtedness;

                                       3

     Term  Loan  Agreement,  any Swap  Agreement  or any  other  Loan  Document,

     amount of, or the  interest  rates  applicable  to,  any of the  Guaranteed
     Indebtedness guaranteed hereby;

          (iii)  any  release,  surrender,   compromise,   settlement,   waiver,
     subordination  or  modification,  with  or  without  consideration,  of any
     collateral  securing the Guaranteed  Indebtedness or any part thereof,  any
     other  guaranties  with respect to the Guaranteed  Indebtedness or any part
     thereof,  or any other  obligation  of any person or entity with respect to
     the Guaranteed  Indebtedness or any part thereof,  or any  nonperfection or
     invalidity  of  any  direct  or  indirect   security  for  the   Guaranteed
     Indebtedness;

          (iv) any  change in the  corporate,  partnership  or other  existence,
     structure or ownership of any Borrower or any other guarantor of any of the
     Guaranteed Indebtedness, or any insolvency,  bankruptcy,  reorganization or
     other similar  proceeding  affecting any Borrower or any other guarantor of
     the  Guaranteed  Indebtedness,  or any of their  respective  assets  or any
     resulting  release or  discharge of any  obligation  of any Borrower or any
     other guarantor of any of the Guaranteed Indebtedness;

          (v) the  existence  of any  claim,  setoff or other  rights  which the
     Guarantors may have at any time against any Borrower,  any other  guarantor
     of  any of the  Guaranteed  Indebtedness,  the  Administrative  Agent,  any
     Secured  Party or any other Person,  whether in  connection  herewith or in
     connection  with any unrelated  transactions,  provided that nothing herein
     shall --------  prevent the assertion of any such claim by separate suit or
     compulsory counterclaim;

          (vi) the enforceability or validity of the Guaranteed  Indebtedness or
     any part  thereof or the  genuineness,  enforceability  or  validity of any
     agreement  relating thereto or with respect to any collateral  securing the
     Guaranteed  Indebtedness  or any part thereof,  or any other  invalidity or
     unenforceability relating to or against any Borrower or any other guarantor
     of any of the Guaranteed Indebtedness, for any reason related to the Second
     Lien Term Loan Agreement, any Swap Agreement or any other Loan Document, or
     any  provision of applicable  law or regulation  purporting to prohibit the
     payment  by  any  Borrower  or  any  other   guarantor  of  the  Guaranteed
     Indebtedness, of any of the Guaranteed Indebtedness;

          (vii) the  failure  of the  Administrative  Agent to take any steps to
     perfect and maintain  any  security  interest in, or to preserve any rights
     to, any security or collateral for the Guaranteed Indebtedness, if any;

          (viii)the election by, or on behalf of, any one or more of the Holders
     of Secured  Indebtedness,  in any proceeding instituted under Chapter 11 of

     Code"), of the application of Section 1111(b)(2) of the Bankruptcy Code;

          (ix) any borrowing or grant of a security interest by any Borrower, as
     debtor-in-possession, under Section 364 of the Bankruptcy Code;

                                       4
<PAGE>

          (x) the disallowance, under Section 502 of the Bankruptcy Code, of all
     or any portion of the claims of the Secured  Parties or the  Administrative
     Agent for repayment of all or any part of the Guaranteed Indebtedness;

          (xi) the  failure of any other  guarantor  to sign or become  party to
     this Guaranty or any amendment, change, or reaffirmation hereof; or

          (xii)  any other  act or  omission  to act or delay of any kind by any
     Borrower,  any  other  guarantor  of  the  Guaranteed   Indebtedness,   the
     Administrative  Agent,  any Secured  Party or any other Person or any other
     circumstance whatsoever which might, but for the provisions of this Section
     3, constitute a legal or equitable discharge of any Guarantor's obligations
     hereunder.

     Section 4.  Discharge Only Upon Payment In Full;  Reinstatement  In Certain
Circumstances.  Each of the  Guarantors'  obligations  hereunder shall remain in
full force and effect until all Guaranteed  Indebtedness  (other than contingent
indemnity obligations and Indebtedness in respect of Swap Agreements) shall have
been paid in full in cash and the  Commitments  under the Second  Lien Term Loan
Agreement  shall have  terminated or expired.  If at any time any payment of the
principal of or interest on any Loan or any other amount payable by any Borrower
or any other party under the Second Lien Term Loan Agreement, any Swap Agreement
or any other  Loan  Document  is  rescinded  or must be  otherwise  restored  or
returned upon the insolvency,  bankruptcy or  reorganization  of any Borrower or
otherwise,  each of the Guarantors'  obligations  hereunder with respect to such
payment  shall be reinstated as though such payment had been due but not made at
such time.

     Section 5. General Waivers; Additional Waivers.

     (A) General Waivers.  Each of the Guarantors  irrevocably waives acceptance
hereof,  presentment,  demand or  action on  delinquency,  protest  and,  to the
fullest extent permitted by law, any notice not provided for herein or under the
other Loan Documents,  as well as any requirement that at any time any action be
taken by any Person against any Borrower,  any other guarantor of the Guaranteed
Indebtedness, or any other Person.

     (B) Additional  Waivers.  Notwithstanding  anything herein to the contrary,
each  of the  Guarantors  hereby  absolutely,  unconditionally,  knowingly,  and
expressly waives:

          (i) any  right  it may  have to  revoke  this  Guaranty  as to  future
     indebtedness or notice of acceptance hereof;

          (ii) (1) notice of acceptance hereof; (2) notice of any loans or other
     financial  accommodations  made or extended under the Loan Documents or the
     creation or existence  of any  Guaranteed  Indebtedness;  (3) notice of the
     amount  of  the  Guaranteed   Indebtedness,   subject,   however,  to  each
     Guarantor's  right to make  inquiry  of  Administrative  Agent and  Secured
     Parties to  ascertain  the  amount of the  Guaranteed  Indebtedness  at any
     reasonable  time;  (4)  notice  of any  adverse  change  in  the  financial
     condition  of any  Borrower or of any other fact that might  increase  such
     Guarantor's risk hereunder;  (5) notice of presentment for payment, demand,
     protest, and notice thereof as to any instruments among the Loan Documents;
     (6) notice of any Default or Event of

                                       5
<PAGE>

     Default;  and (7) all other notices  (except if such notice is specifically
     required  to be  given  to such  Guarantor  hereunder  or  under  the  Loan
     Documents) and demands to which each Guarantor might otherwise be entitled;

          (iii) its right, if any, to require the  Administrative  Agent and the
     other Secured  Parties to institute suit against,  or to exhaust any rights
     and remedies which the  Administrative  Agent and the other Secured Parties
     have or may have  against,  the other  Guarantors  or any third  party,  or
     against any collateral provided by the other Guarantors or any third party;
     and each  Guarantor  further  waives any  defense  arising by reason of any
     disability  or other  defense  (other than the defense that the  Guaranteed
     Indebtedness  shall have been fully and finally  performed and indefeasibly
     paid) of the other  Guarantors or by reason of the cessation from any cause
     whatsoever of the liability of the other Guarantors in respect thereof;

          (iv) (a) any rights to assert against the Administrative Agent and the
     other  Secured   Parties  any  defense  (legal  or   equitable),   set-off,
     counterclaim,  or  claim  which  such  Guarantor  may  now or at  any  time
     hereafter  have against the other  Guarantors  or any other party liable to
     the  Administrative  Agent and the other Secured Parties;  (b) any defense,
     set-off, counterclaim, or claim, of any kind or nature, arising directly or
     indirectly  from the  present or future  lack of  perfection,  sufficiency,
     validity, or enforceability of the Guaranteed  Indebtedness or any security
     therefor;  and (c) any defense such Guarantor has to performance hereunder,
     and any right such  Guarantor has to be  exonerated,  arising by reason of:
     the  impairment or suspension of the  Administrative  Agent's and the other
     Secured  Parties'  rights or  remedies  against the other  Guarantors;  the
     alteration by the Administrative Agent and the other Secured Parties of the
     Guaranteed Indebtedness; any discharge of the other Guarantors' obligations
     to the  Administrative  Agent and the other Secured Parties by operation of
     law as a  result  of the  Administrative  Agent's  and  the  other  Secured
     Parties'  intervention or omission; or the acceptance by the Administrative
     Agent and the other Secured Parties of anything in partial  satisfaction of
     the Guaranteed Indebtedness; and

          (v) any defense arising by reason of or deriving from (a) any claim or
     defense based upon an election of remedies by the Administrative  Agent and
     the other Secured Parties; or (b) any election by the Administrative  Agent
     and the other  Secured  Parties  under  Section  1111(b) of Title 11 of the
     United  States Code entitled  "Bankruptcy",  as now and hereafter in effect
     (or any  successor  statute),  to limit the  amount  of, or any  collateral
     securing, its claim against the Guarantors:

     Section 6. Subordination of Subrogation.  Until the Guaranteed Indebtedness
have been paid in full in cash and  finally  performed  (other  than  contingent
indemnity  obligations and  Indebtedness in respect of the Swap  Agreements) the
Guarantors  (i)  shall  have  no  right  of  subrogation  with  respect  to such
Guaranteed Indebtedness and (ii) waive any right to enforce any remedy which the
Secured  Parties  or the  Administrative  Agent now have or may  hereafter  have
against any  Borrower,  any endorser or any  guarantor of all or any part of the
Indebtedness or any other Person,  and until such time the Guarantors  waive any
benefit of, and any right to participate in, any security or collateral given to
the  Secured  Parties  and the  Administrative  Agent to secure  the  payment or
performance  of  all or any  part of the  Guaranteed  Indebtedness or

                                       6
<PAGE>

any  other  liability  of each  Borrower  to the  Secured  Parties.  Should  any
Guarantor  have the  right,  notwithstanding  the  foregoing,  to  exercise  its
subrogation   rights,  each  Guarantor  hereby  expressly  and  irrevocably  (A)
subordinates   any  and  all  rights  at  law  or  in  equity  to   subrogation,
reimbursement,  exoneration,  contribution,  indemnification or set off that the
Guarantor may have to the payment in full in cash of the Guaranteed Indebtedness
until  the  Guaranteed  Indebtedness  are  paid  in full  in  cash  (other  than
contingent indemnity obligations and Indebtedness in respect of Swap Agreements)
and  (B)  waives  any and all  defenses  available  to a  surety,  guarantor  or
accommodation  co-obligor until the Guaranteed  Indebtedness are paid in full in
cash (other than contingent  indemnity  obligations  other than  Indebtedness in
respect of Swap  Agreements).  Each Guarantor  acknowledges and agrees that this
subordination  is intended to benefit the  Administrative  Agent and the Secured
Parties  and shall not limit or  otherwise  affect  such  Guarantor's  liability
hereunder or the  enforceability of this Guaranty,  and that the  Administrative
Agent,  the Secured  Parties  and their  respective  successors  and assigns are
intended  third party  beneficiaries  of the waivers and agreements set forth in
this Section 6.

     Section 7. Contribution with Respect to Guaranteed Indebtedness.

     (a) To the  extent  that any  Guarantor  shall  make a payment  under  this
Guaranty (a "Guarantor  Payment") which, taking into account all other Guarantor
Payments then previously or concurrently  made by any other  Guarantor,  exceeds
the  amount  which  otherwise  would have been paid by or  attributable  to such
Guarantor  if each  Guarantor  had paid the  aggregate  Guaranteed  Indebtedness
satisfied by such Guarantor  Payment in the same proportion as such  Guarantor's
"Allocable  Amount" (as defined below) (as determined  immediately prior to such
Guarantor  Payment)  bore  to the  aggregate  Allocable  Amounts  of each of the
Guarantors  as  determined  immediately  prior to the  making of such  Guarantor
Payment,  then,  following  payment in full in cash of the Guarantor Payment and
the Guaranteed  Indebtedness  (other than contingent  indemnity  obligations and
Indebtedness in respect of Swap Agreements), and all Commitments have terminated
or  expired,  such  Guarantor  shall be  entitled  to receive  contribution  and
indemnification  payments from,  and be reimbursed by, each other  Guarantor for
the  amount of such  excess,  pro rata based  upon  their  respective  Allocable
Amounts in effect immediately prior to such Guarantor Payment.

     (b)  As of  any  date  of  determination,  the  "Allocable  Amount"  of any
Guarantor  shall be equal to the maximum amount of the claim which could then be
recovered from such Guarantor under this Guaranty  without  rendering such claim
voidable or avoidable  under Section 548 of Chapter 11 of the Bankruptcy Code or
under any applicable state Uniform  Fraudulent  Transfer Act, Uniform Fraudulent
Conveyance Act or similar statute or common law.

     (c) This Section 7 is intended  only to define the  relative  rights of the
Guarantors,  and  nothing  set forth in this  Section 7 is  intended to or shall
impair the  obligations of the  Guarantors,  jointly and  severally,  to pay any
amounts as and when the same shall become due and payable in accordance with the
terms of this Guaranty.

     (d) The parties  hereto  acknowledge  that the rights of  contribution  and
indemnification hereunder shall constitute assets of the Guarantor or Guarantors
to which such contribution and indemnification is owing.

                                       7
<PAGE>

     (e) The rights of the indemnified Guarantors against other Guarantors under
this Section 7 shall be exercisable  upon the full and  indefeasible  payment of
the Guaranteed  Indebtedness  (other than contingent  indemnity  obligations and
Indebtedness in respect of Swap  Agreements) in full in cash and the termination
or expiry (or in the case of all Letters of Credit full  collateralization),  on
terms  reasonably  acceptable to the  Administrative  Agent,  of the Commitments
under the Second Lien Term Loan Agreement.

     Section 8. Stay of Acceleration. If acceleration of the time for payment of
any amount  payable by any Borrower  under the Second Lien Term Loan  Agreement,
any counterparty to any Swap Agreement or any other Loan Document is stayed upon
the  insolvency,  bankruptcy or  reorganization  of any Borrower or any of their
Affiliates,  all such amounts otherwise subject to acceleration  under the terms
of the Second Lien Term Loan  Agreement,  any Swap  Agreement  or any other Loan
Document  shall  nonetheless  be  payable  by each of the  Guarantors  hereunder
forthwith  on  demand by the  Administrative  Agent.

     Section 9. Notices.  All notices,  requests and other communications to any
party hereunder shall be given in the manner  prescribed in Section 12.01 of the
Second Lien Term Loan Agreement with respect to the Administrative  Agent at its
notice address  therein and, with respect to any  Guarantor,  in the care of the
Borrowers at the address of the Borrowers set forth in the Second Lien Term Loan
Agreement,  or such other address or telecopy number as such party may hereafter
specify for such  purpose by notice to the  Administrative  Agent in  accordance
with the provisions of such Section 12.01.

     Section 10. No Waivers. No failure or delay by the Administrative  Agent or
any Secured Party in exercising any right,  power or privilege  hereunder  shall
operate as a waiver  thereof  nor shall any single or partial  exercise  thereof
preclude  any other or further  exercise  thereof or the  exercise  of any other
right,  power or privilege.  The rights and remedies  provided in this Guaranty,
the  Second  Lien Term Loan  Agreement,  any Swap  Agreement  and the other Loan
Documents  shall be  cumulative  and not  exclusive  of any  rights or  remedies
provided by law.

     Section 11. Successors and Assigns. This Guaranty is for the benefit of the

Secured Party or the Administrative Agent to any Guarantor, and (ii) any moneys,

the Guaranteed  Indebtedness,  and of all other  circumstances  bearing upon the
risk of nonpayment of the  Guaranteed  Indebtedness,  or any part thereof,  that
diligent inquiry would reveal, and each Guarantor hereby agrees that none of the
Secured  Party or the  Administrative  Agent  shall have any duty to advise such
Guarantor of  information  known to any of them  regarding such condition or any
such circumstances.  In the event any Secured Party or the Administrative Agent,
in its sole  discretion,  undertakes at any time or from time to time to provide
any such  information to a Guarantor,  such Secured Party or the  Administrative
Agent shall be under no obligation (i) to undertake any investigation not a part

<PAGE>

to create or reflect only an  administrative  relationship  between  independent
contracting  parties.  The  Lenders  and  the  Swap  Counterparties  irrevocably
authorize the Collateral Agent, at its option and in its discretion,  to release

Agreement or the Security Documents by or through agents, employees or

consultants or experts concerning all matters pertaining to such duties. The
Collateral Agent shall not be responsible for the negligence or misconduct of
any agent or attorney-in-fact that it selects in the absence of gross negligence
or willful misconduct.

            (e) No Collateral Agent-Related Person shall (i) be liable for any
action taken or omitted to be taken by any of them under or in connection with
this Agreement or the Security Documents or the transactions contemplated hereby
and thereby including but not limited to those arising from its own negligence
(except for its own gross negligence or willful misconduct in connection with
its duties expressly set forth herein), or (ii) be responsible in any manner to
any Lender, Swap Counterparty or participant for any recital, statement,
representation or warranty made by the Loan Parties, or any officer thereof,
contained herein or in the Security Documents, or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Collateral Agent under or in connection with, this Agreement or the Security
Documents, or the validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or the Security Documents, or for any failure of
the Loan Parties to perform their obligations hereunder or thereunder. No
Collateral Agent-Related Person shall be under any obligation to any Lender or
participant to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement, the Senior
Secured Loan Documents, the Second Lien Loan Documents, this Agreement, the
Security Documents, or to inspect the properties, books or records of the Loan
Parties.

            (f) The Collateral Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, communication, signature,
resolution, representation, notice, consent, certificate, affidavit, letter,
telegram, facsimile, telex or telephone message, electronic mail message,
statement or other document or conversation reasonably believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons, and upon advice and statements of legal counsel (including counsel
to the Loan Parties), independent accountants and other experts selected by the
Collateral Agent. The Collateral Agent shall be fully justified in failing or
refusing to take any action under the Security Documents unless it shall first
receive such advice or concurrence of Senior Administrative Agent as it deems
appropriate and, if it so requests, it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
Collateral Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement or the Security Documents in
accordance with a request or consent of Senior Administrative Agent and such
request and any

                                       12
<PAGE>

action  taken or failure to act pursuant  thereto  shall be binding upon all the
Lenders and Swap Counterparties.

            (g) The Collateral Agent shall not be deemed to have knowledge or
notice of the occurrence of any "Default" or "Event of Default" under the Senior
Secured Credit Agreement, the Second Lien Credit Agreement, the Security
Documents or any Swap Agreement (as "Default" or "Event of Default" is defined
in any of such documents) or unless the Collateral Agent shall have received
written notice from the Senior Administrative Agent or Second Lien
Administrative Agent, as applicable, or a Borrower, describing such "Default" or
"Event of Default" and stating that such notice is a "notice of default." The
Collateral Agent will notify Senior Administrative Agent and the Second Lien
Administrative Agent of its receipt of any such notice. The Collateral Agent
shall take such action with respect to the Collateral after any such "Default"
or "Event of Default" as may be directed by Senior Administrative Agent in
accordance with the terms hereof until the Senior Secured Indebtedness has been
paid in full in cash and all Commitments under the Senior Secured Credit
Agreement have been terminated and thereafter as directed by the Second Lien
Administrative Agent in accordance with the terms of hereof. Unless and until
the Collateral Agent has received any such direction, the Collateral Agent shall
not be obligated to take such action with respect to such "Default" or "Event of
Default". Furthermore, the Collateral Agent may (but shall not be obligated to)
take action hereunder to the extent necessary to maintain insurance on the
Collateral or otherwise protect the Collateral from damage or destruction.

            (h) Each Lender acknowledges that no Collateral Agent-Related Person
has made any representation or warranty to it, and that no act by the Collateral
Agent hereafter taken, including any consent to and acceptance of any assignment
or review of the affairs of the Loan Parties, shall be deemed to constitute any
representation or warranty by any Collateral Agent-Related Person to any Lender
as to any matter, including whether Collateral Agent-Related Persons have
disclosed material information in their possession. Each Lender and Swap
Counterparty represents to the Collateral Agent that it has, independently and
without reliance upon any Collateral Agent-Related Person and based on such
documents and information as it has deemed appropriate, made its own appraisal
of and investigation into the business, prospects, operations, property,
financial and other condition and creditworthiness of the Loan Parties, and all
applicable bank or other regulatory laws relating to the transactions
contemplated hereby, and made its own decision to enter into the Senior Secured
Loan Documents or Second Lien Loan Documents, as applicable, and this Agreement
and to extend credit to Borrowers under the applicable credit agreement. Each
Lender and each Swap Counterparty also represents that it will, independently
and without reliance upon any Collateral Agent-Related Person and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit analysis, appraisals and decisions in taking or not taking
action under this Agreement and the Senior Secured Loan Documents, Swap
Agreement or Second Lien Loan Documents, as applicable, and to make such
investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Loan Parties. Except for notices, reports and other
documents expressly required to be furnished to Senior Administrative Agent or
Second Lien Administrative Agent by the Collateral Agent herein, the Collateral
Agent shall not have any duty or responsibility to provide any Lender or Swap
Counterparty with any credit or other information concerning the business,

                                       13
<PAGE>

prospects, operations, property, financial and other condition or
creditworthiness of any of the Loan Parties which may come into the possession
of any Collateral Agent-Related Person.

            (i) The Lenders shall indemnify upon demand each Collateral
Agent-Related Person (to the extent not reimbursed by or on behalf of the Loan
Parties and without limiting the obligation of the Loan Parties to do so), to
the extent of each Lender's Proportionate Share, and hold harmless each
Collateral Agent-Related Person from and against any and all Indemnified
Liabilities incurred by it, including but not limited to those arising from its
own negligence; provided, however, that no Lender shall be liable for the
payment to any Collateral Agent-Related Person of any portion of such
Indemnified Liabilities to the extent determined in a final, nonappealable
judgment by a court of competent jurisdiction to have resulted from such
Collateral Agent-Related Person's own gross negligence or willful misconduct;
provided further, however, that no action taken in accordance with the
directions of Senior Administrative Agent or Second Lien Administrative Agent
shall be deemed to constitute gross negligence or willful misconduct for
purposes of this Section 3(i). Without limitation of the foregoing, each Lender
shall reimburse the Collateral Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including reasonable attorney's fees and
expenses) incurred by the Collateral Agent in connection with the preparation,
execution, delivery, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal
advice in respect of rights or responsibilities under, this Agreement or the
Security Documents to the extent that the Collateral Agent is not reimbursed for
such expenses by or on behalf of the Loan Parties. The undertaking in this
Section 3(i) shall survive termination of the Senior Secured Credit Agreement
and the Second Lien Credit Agreement.

            (j) Guggenheim Corporate Funding, LLC, and its Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in, enter into hedging and derivative agreements, and
generally engage in any kind of banking, trust, financial advisory, underwriting
or other business with the Loan Parties as though Guggenheim Corporate Funding,
LLC were not the Collateral Agent hereunder and without notice to or consent of
the Lenders. The Lenders acknowledge that, pursuant to such activities,
Guggenheim Corporate Funding, LLC or its Affiliates may receive information
regarding the Loan Parties (including information that may be subject to
confidentiality obligations in favor of the Loan Parties) and acknowledge that
the Collateral Agent shall be under no obligation to provide such information to
them. With respect to the Collateral, Guggenheim Corporate Funding, LLC shall
have the same rights and powers under this Agreement and the Security Documents
as any other Lender and may exercise such rights and powers as though it were
not the Collateral Agent, and the terms "Lender" and "Lenders" include
Guggenheim Corporate Funding, LLC in its individual capacity.

            (k) Successor Collateral Agent.

            (i) The Collateral Agent may resign as Collateral Agent upon not
      less than 20 days' notice to the Lenders, with such resignation to take
      effect upon the acceptance by a successor Collateral Agent of its
      appointment as the Collateral Agent hereunder. In addition in the event
      the Collateral Agent is no longer a Lender or the Senior Administrative
      Agent, the Required Lenders may remove the Collateral Agent by giving
      written notice thereof to the Collateral Agent at least 20 days' prior to
      the effective date of

                                       14
<PAGE>

      such removal. Upon any such resignation or removal,
      the Required Lenders shall have the right to appoint a successor
      Collateral Agent. If no successor Collateral Agent shall have been so
      appointed and shall have accepted such appointment in writing within 20
      days after the retiring Collateral Agent's giving of notice of resignation
      or its removal, then the retiring Collateral Agent may, on behalf of the
      Lenders, appoint a successor Collateral Agent which meets the eligibility
      requirements of paragraph (k)(iii) below. Upon acceptance of appointment
      as Collateral Agent, such successor shall thereupon and forthwith succeed
      to and become vested with all the rights, powers and privileges,
      immunities and duties of the retiring Collateral Agent, the term
      "Collateral Agent" shall mean such successor Collateral Agent, and the
      retiring Collateral Agent, upon the transferring and setting over to such
      successor Collateral Agent all rights, moneys and other collateral held by
      it in its capacity as Collateral Agent, shall be discharged from its
      duties and obligations hereunder. After any retiring Collateral Agent's
      resignation or removal hereunder as Collateral Agent, the provisions of
      this paragraph (k)(i) shall inure to its benefit as to any actions taken
      or omitted to be taken by it while it was Collateral Agent under this
      Agreement.

            (ii) Any successor Collateral Agent appointed hereunder shall
      execute, acknowledge and deliver to Borrowers, the Senior Administrative
      Agent, the Senior Secured Lenders, the Second Lien Administrative Agent,
      the Second Lien Lenders and the predecessor Collateral Agent an instrument
      accepting such appointment, and thereupon such successor Collateral Agent,
      without any further act, deed, conveyance or transfer, shall become vested
      with the title to the Collateral, and with all the rights, powers, duties
      and obligations of the predecessor Collateral Agent in the trust
      hereunder, with like effect as if originally named as Collateral Agent
      herein. Upon the request of any such successor Collateral Agent, Borrowers
      and the predecessor Collateral Agent shall promptly execute and deliver
      such instruments of conveyance and further assurance reflecting terms
      consistent with the terms of the Senior Secured Loan Documents and the
      Second Lien Loan Documents then in effect and do such other things as may
      reasonably be required for more fully and certainly vesting and confirming
      in such successor Collateral Agent its interest in the Collateral and all
      such rights, powers, duties and obligations of the predecessor Collateral
      Agent hereunder, and the predecessor Collateral Agent shall also promptly
      assign and deliver to the successor Collateral Agent any Collateral
      subject to the lien and security interest of this Agreement which may then
      be in its possession.

            (iii) Any successor Collateral Agent appointed by a retiring
      Collateral Agent pursuant to paragraph (k)(i) above shall be a state or
      national bank or trust company in good standing, organized under the laws
      of the United States of America or of any state, having a capital, surplus
      and undivided profits aggregating at least $500,000,000 and whose
      certificates of deposit have a Satisfactory Rating, if there be such a
      bank or trust company willing and able to accept the duties hereunder upon
      reasonable and customary terms. As used in this paragraph (k)(iii), the
      term "Satisfactory Rating" means, with respect to any Person, that such
      Person and its bank deposits or other short term credit obligations have
      both a short-term bank deposit rating of Prime-2 or better from Moody's
      Investors Service, Inc. and a short term credit obligation rating of A-3
      or better from Standard and Poor's Rating Service, a division of The
      McGraw-Hill Companies.

                                       15
<PAGE>

            (iv) Any corporation or limited liability company into which the
      Collateral Agent may be merged or with which it may be consolidated, or
      any corporation or limited liability company resulting from any merger or
      consolidation to which the Collateral Agent shall be a party, shall be the
      successor of the Collateral Agent hereunder without the execution or
      filing of any paper or any further act on the part of any of the parties
      hereto, anything to the contrary contained herein notwithstanding.

            (l) Whenever Collateral Agent in good faith determines that it is
uncertain about how to distribute any funds which it has received, or whenever
Collateral Agent in good faith determines that there is any dispute among
Lenders and/or Swap Counterparties about how such funds should be distributed,
Collateral Agent may choose to defer distribution of the funds which are the
subject of such uncertainty or dispute. If Collateral Agent in good faith
believes that the uncertainty or dispute will not be promptly resolved, or if
Collateral Agent is otherwise required to invest funds pending distribution to
Lenders, Collateral Agent shall invest such funds pending distribution; all
interest on any such investment shall be distributed upon the distribution of
such investment and in the same proportion and to the same Persons as such
investment. All moneys received by Collateral Agent for distribution to Lenders
and Swap Counterparties shall be held by Collateral Agent pending such
distribution solely as Collateral Agent for such Lenders and Swap
Counterparties, and Collateral Agent shall have no equitable title to any
portion thereof except in its separate capacity as a Lender.

            (m) The Second Lien Administrative Agent and each Second Lien Lender
hereby waives and agrees not to assert: (i) any right, now or hereafter
existing, to require Collateral Agent or the Senior Secured Creditor to proceed
against or exhaust any Collateral at any time securing the Senior Secured
Indebtedness or amounts payable under any Swap Agreement, or to marshal any
assets in favor of Second Lien Administrative Agent, any Second Lien Lender or
any other holder of Second Lien Indebtedness or to receive notice that the
Collateral Agent has elected to, or is pursuing, remedies against the
Collateral; and (ii) any notice of the incurrence of Senior Secured
Indebtedness, it being understood that Senior Secured Lenders may, in reliance
upon these subordination provisions, make advances under the Senior Secured Loan
Documents, or any other agreement, document, or instrument now or hereafter
relating to the Senior Secured Indebtedness (in compliance with the terms of
this Agreement), without notice to or authorization of Second Lien
Administrative Agent.

            (n) For the limited purpose of perfecting the security interests of
the Senior Secured Creditor and the Second Lien Creditor in those types or items
of Collateral in which a security interest may only be perfected by possession
or control, each of the Senior Administrative Agent and the Second Lien
Administrative Agent hereby appoints the Collateral Agent as its agent and
bailee for the limited purpose of possessing or controlling on its behalf any
such Collateral that is in or may come into the possession of the Collateral
Agent from time to time, and the Collateral Agent agrees to act as the agent and
bailee for such limited purpose of perfecting the Senior Administrative Agent's
and the Second Lien Administrative Agent's security interests by possession or
control through an agent or bailee.

      Section 4. Collateral Accounts.
                 -------------------

            (a) The Collateral Agent shall maintain one or more accounts (the
"Collateral Accounts") into which shall be deposited all amounts received by it
in its capacity as the Collateral Agent, in respect of any Senior Secured Loan
Document or Second Lien Loan Document, including all proceeds of Collateral. The
Collateral Accounts referred to in the preceding sentence shall be established
and maintained for the benefit of all Secured Parties. The Collateral Agent, for
the benefit of the Agents, the Lenders and the Swap Counterparties, shall have
exclusive dominion and control over the Collateral Accounts.

            (b) Prior to the delivery of Notice of Default, any amounts
deposited in the Collateral Accounts shall be disbursed to the Borrowers. After
the delivery of a Notice of Default, all amounts deposited in the Collateral
Accounts shall be disbursed only as provided in Section 5 hereof.

     Section 5. Application of Proceeds. All amounts deposited in the Collateral
Accounts shall be applied in the following order of priority:

            (i) first, to pay obligations in respect of any expense
      reimbursements, indemnities or other liabilities then due to any Agent
      until such obligations have been paid in full;

            (ii) second, to pay obligations in respect of any fees then due to
      any Agent or the Issuing Bank until such obligations have been paid in
      full;

            (iii) third, to pay interest due and unpaid in respect of the Senior
      Secured Revolving Loans and the reimbursement obligations with respect to
      any letter of credit until such interest has been paid in full; (iv)
      fourth, to pay (A) all amounts due and payable pursuant to the terms of
      any Swap Agreement, and (B) the principal outstanding on the amounts
      payable under Senior Secured Revolving Loans until such amounts payable
      under Swap Agreements and Senior Secured Revolving Loans have been paid in
      full;

            (v) fifth, to cash collateralize the LC Exposure under of the Senior
      Secured Credit Agreement;

            (vi) sixth, to pay interest due and unpaid in respect of the Senior
      Secured Term Loans until such interest has been paid in full;

            (vii) seventh, to pay the principal outstanding on the Senior
      Secured Term Loans until the Senior Secured Term Loans have been paid in
      full;

            (viii) eighth, to pay interest due and unpaid in respect of the
      Second Lien Indebtedness until such interest has been paid in full;

            (ix) ninth, to pay the principal outstanding on the Second Lien
      Indebtedness until the Second Lien Indebtedness has been paid in full;

                                       17
<PAGE>

            (x) tenth, to the Borrowers;

provided, however, if sufficient funds are not available to fund all payments to
be made in respect of any of the obligations described in any one of the
foregoing clauses (i) through (ix), the available funds being applied with
respect to any such obligations referred to in such clause shall be allocated to
the payment of such obligations ratably, based on the proportion of each
Agent's, each Lender's, each Swap Counterparty's or the Issuing Bank's interest
in the aggregate outstanding obligations described in such clause.

      Section 6. Payment Default or Acceleration. Except under circumstances
when the terms of Section 9 of this Agreement are applicable, if (a) a Payment
Default or Senior Indebtedness Acceleration shall have occurred and be
continuing and (b) the Second Lien Lenders or the Second Lien Administrative
Agent or other representative shall have received a Payment Default Notice, then
neither of the Borrowers nor any Subsidiary may make, and no Second Lien Lender
shall accept, receive or collect, any direct or indirect payment or distribution
of any kind or character (in cash, securities, other Property, by setoff, or
otherwise other than Reorganization Securities) of any properties or assets of
the Borrowers or any of their Subsidiaries on account of the Subordinated
Obligations during the Payment Blockage Period; provided, however, that in the
case of any payment on or in respect of any Subordinated Obligation that would
(in the absence of any such Payment Default Notice) have been due and payable on
any date (a "Scheduled Payment Date") during such Payment Blockage Period
pursuant to the terms of the Second Lien Credit Agreement or the Second Lien
Notes, if requested, as in effect on the date hereof or as amended consistent
with the provisions of Section 15 of this Agreement, the provisions of this
Section 6 shall not prevent the making and acceptance of such payment (a
"Scheduled Payment"), together with any additional default interest as is due on
Second Lien Credit Agreement or the Second Lien Notes, on or after the date
immediately following the termination of such Payment Blockage Period. In the
event that, notwithstanding the foregoing, either of the Borrowers or any of
their Subsidiaries shall make any payment or distribution to any Second Lien
Lender prohibited by the foregoing provisions of this Section 6, then and in
such event such payment or distribution shall be held in trust for the benefit
of and immediately shall be paid over to the Collateral Agent for application as
set forth in Section 5 of this Agreement. Any Payment Default Notice shall be
deemed received by the Second Lien Lenders upon the date of actual receipt by
the Second Lien Lenders or the Second Lien Administrative Agent or other
representative designated pursuant to Section 16 hereof of such Payment Default
Notice in writing.

      Section 7. Non-Payment Default. Except under circumstances when the terms
of this Section 6 or Section 9 of this Agreement are applicable, if (a) a
Non-Payment Default shall have occurred and be continuing, (b) the Second Lien
Lenders or the Second Lien Administrative Agent or other representative
designated pursuant to Section 16 hereof shall have received a Non-Payment
Default Notice, and (c) no Non-Payment Default Notice shall have been given
within the 360 day period immediately preceding the giving of such Non-Payment
Default Notice, then neither of the Borrowers nor any Subsidiary may make, and
no Second Lien Lender shall accept, receive or collect, any direct or indirect
payment or distribution of any kind or character (in cash, securities, other
Property, by setoff, or otherwise other than Reorganization Securities) of any
properties or assets of either of the Borrowers or any Subsidiary on account of
the Subordinated Obligations during the Non-Payment Blockage Period; provided,
however, that

                                       18
<PAGE>

in the  case of any  Scheduled  Payment  on or in  respect  of any  Subordinated
Obligation  that would (in the absence of any such  Non-Payment  Default Notice)
have been due and payable on any Scheduled  Payment Date during such Non-Payment
Blockage  Period  pursuant to the terms of the Second Lien Loan  Documents as in
effect on the date  hereof or as amended  consistent  with the  requirements  of
Section 15 of this Agreement, the provisions of this Section 7 shall not prevent
the  making  and  acceptance  of  such  Scheduled  Payment,  together  with  any
additional  default  interest as is due on the Second Lien Notes,  if any, on or
after  the  date  immediately  following  the  termination  of such  Non-Payment
Blockage Period. In the event that, notwithstanding the foregoing, either of the
Borrowers or any Subsidiary shall make any payment or distribution to any Second
Lien Lender  prohibited by the foregoing  provisions of this Section 7, then and
in such  event  such  payment  or  distribution  shall be held in trust  for the
benefit  of and  immediately  shall be paid  over to the  Collateral  Agent  for
application  pursuant to Section 5 of this Agreement.  Any  Non-Payment  Default
Notice  shall be deemed  received  by the Second Lien  Lenders  upon the date of
actual  receipt by the Second  Lien  Lenders or the Second  Lien  Administrative
Agent or other representative of such Non-Payment Default Notice in writing.

      Section 8. Standstill. At any time that the Second Lien Lenders are not
permitted to receive payments on the Subordinated Obligations pursuant to either
Section 6 or 7 of this Agreement, the Second Lien Lenders and the Second Lien
Administrative Agent or other representative of the Second Lien Lenders
designated hereunder will not commence any Enforcement Action relative to either
of the Borrowers or any of their Subsidiaries during the Standstill Period. Upon
the termination of the Standstill Period, the Second Lien Lenders may exercise
all rights or remedies they may have in law or equity; provided, however, that
if a Standstill Period terminates pursuant to clause (e) of the definition
thereof, no Second Lien Lender and no agent or representative thereof shall
exercise any remedies against, or attempt to foreclose upon, garnish, sequester
or execute upon, any Property known to it as constituting Collateral (other than
to file or record any judgment Liens it may have obtained against such
Collateral) during the period that such Standstill Period would have been in
effect but for termination pursuant to clause (e) of the definition of
"Standstill Period;" provided further, that the Payment Blockage Period or the
Non-Payment Blockage Period, as the case may be, if not also terminated, shall
continue for its full period notwithstanding the termination of the Standstill
Period. Notwithstanding the foregoing, no Standstill Period may be commenced
while any other Standstill Period exists or within 180 days following the
termination of any prior Standstill Period (provided that this sentence shall
not relieve any Second Lien Lender of its obligation to provide notice under
Section 12 of this Agreement).

      Section 9. Insolvency; Bankruptcy; Etc. In the event of the institution of
any Insolvency Proceeding relative to either of the Borrowers or any of their
Subsidiaries, then:

            (a) The holders of the Senior Secured Indebtedness shall be entitled
to receive payment in full in cash of the Senior Indebtedness and cash
collateral in respect of all outstanding letters of credit and Swap
Counterparties shall be entitled to receive all amounts payable under the Swap
Agreements, in each case as provided pursuant to Section 5 of this Agreement,
before the Second Lien Lenders are entitled to receive any direct or indirect
payment or distribution of any kind or character, whether in cash, Property or
securities (other than Reorganization Securities) on account of the Subordinated
Obligations.

                                       19
<PAGE>

            (b) Any direct or indirect payment or distribution of any kind or
character, whether in cash, Property or securities, by setoff or otherwise,
which may be payable or deliverable in such proceedings in respect of the
Subordinated Obligations but for the provisions of this Agreement shall be paid
or delivered by the Person making such payment or distribution, whether either
of the Borrowers, any Subsidiary of the Borrowers, a trustee in bankruptcy, a
receiver, a liquidating trustee, or otherwise, to the Collateral Agent for the
account of the holders of Senior Secured Indebtedness and/or the Swap
Counterparties, to the extent necessary to make payment in full in cash of all
Senior Secured Indebtedness remaining unpaid, to fully cash collateralize all
outstanding letters of credit, and to make payment of amounts payable under the
Swap Agreements; provided, however, that no such delivery of any Reorganization
Securities shall be made to any holders of the Senior Secured Indebtedness or to
any Swap Counterparty. In the event that, notwithstanding the foregoing
provisions of this Section 9, the Senior Secured Creditor or the Second Lien
Creditor shall have received any such payment or distribution of any kind or
character, whether in cash, Property or securities (other than Reorganization
Securities), by setoff or otherwise, then and in such event such payment or
distribution shall be held in trust for the benefit of, and immediately shall be
paid over to, the Collateral Agent for application to the payment of all Senior
Secured Indebtedness, amounts payable under Swap Agreements and Second Lien
Indebtedness remaining unpaid, pursuant to the terms of Section 5 of this
Agreement.

            (c) If no proof of claim is filed in any Insolvency Proceeding with
respect to any Subordinated Obligations by the tenth day prior to the bar date
for any such proof of claim, the Collateral Agent may, after notice to the
Second Lien Lenders or the Second Lien Administrative Agent or other
representative designated pursuant to Section 16 hereof, file such a proof of
claim on behalf of the Second Lien Lenders, and each Second Lien Lender hereby
irrevocably appoints the Collateral Agent as its agent and attorney-in-fact for
such limited purpose; provided, that the foregoing shall not confer to the
holder of any Senior Secured Indebtedness the right to vote on behalf of the
Second Lien Lenders in any Insolvency Proceedings.

      Section 10. No Impairment. No right of any present or future holder of
Senior Secured Indebtedness to enforce subordination as herein provided shall at
any time in any way be prejudiced or impaired by any act or failure to act on
the part of either of the Borrowers or any Subsidiary or by any non-compliance
by either of the Borrowers or any Subsidiary with the terms, provisions, and
covenants of this Agreement, the Second Lien Credit Agreement or the Second Lien
Notes, if any, regardless of any knowledge thereof any such Second Lien Lender
may have or be otherwise charged with. The provisions of this Agreement shall be
enforceable directly by the Collateral Agent, by any present or future holder of
the Senior Secured Indebtedness and/or the Senior Indebtedness Representative.

      Section 11. Rights of Creditors; Subrogation. The provisions of this
Agreement are for the purpose of defining the relative rights of holders of the
Senior Secured Indebtedness, any Swap Counterparty, holders of Senior Secured
Term Indebtedness and the Second Lien Lenders, and nothing herein shall impair,
as between the Borrowers and the Guarantors and the Second Lien Lenders, the
obligation of the Borrowers and the Guarantors, which are unconditional and
absolute, to pay to the Second Lien Lenders the principal of the Second Lien
Indebtedness and interest thereon in accordance with their terms and the
provisions thereof, nor shall anything

                                       20
<PAGE>

herein, except as otherwise provided in Section 8 of this Agreement, prevent the
Second  Lien  Lenders  from  exercising  all  remedies  otherwise  permitted  by
applicable law or hereunder upon default under the Second Lien Credit  Agreement
or under the Second Lien Notes,  if  requested,  (including  the right to demand
payment  and sue for  performance  thereof  and of the  Second  Lien  Notes,  if
requested,  and to accelerate  the maturity  thereof as provided by the terms of
the Second  Lien Credit  Agreement  or the Second  Lien  Notes,  if  requested),
subject to the rights of holders  of the Senior  Secured  Indebtedness  and Swap
Counterparties under this Agreement.  Upon payment in full of the Senior Secured
Indebtedness  in cash and  termination  of the  commitments of any holder of the
Senior Secured Indebtedness to make loans or extensions of credit, expiration or
termination  of all letters of credit  issued  under the Senior  Secured  Credit
Agreement  and payment of any amounts  payable  under the Swap  Agreements,  the
Second Lien Lenders shall, to the extent of any payments or  distributions  paid
or  delivered  to the  Collateral  Agent for  payment  to  holders of the Senior
Secured  Indebtedness  or otherwise  applied to the Senior Secured  Indebtedness
pursuant to the provisions of this Agreement, be subrogated to the rights of the
holders of the Senior Secured  Indebtedness to receive payments or distributions
of assets of the Borrowers or any Guarantor made on Senior Secured  Indebtedness
(and any security therefor) until the Subordinated  Obligations shall be paid in
full (and, for this purpose, no such payments or distributions paid or delivered
to the  Collateral  Agent for  payment  to the  holders  of the  Senior  Secured
Indebtedness  and the Swap  Counterparties  or  otherwise  applied to the Senior
Secured  Indebtedness and any amounts payable under the Swap Agreements shall be
deemed to have discharged the Subordinated  Obligations),  and, for the purposes
of such  subrogation,  no  payments to the  Collateral  Agent for payment to the
holders of the Senior Secured  Indebtedness and Swap Counterparties of any cash,
assets, stock, or obligations to which the Second Lien Lenders would be entitled
except for the provisions of this Agreement  shall, as between the Borrowers and
the Guarantors, any of their respective creditors (other than the holders of the
Senior  Secured  Indebtedness  and Swap  Counterparties),  and the  Second  Lien
Lenders,  be deemed to be a payment by either of the  Borrowers or any Guarantor
to or on account of Subordinated Obligations.  The fact that failure to make any
payment on account of the  Subordinated  Obligations  is caused by reason of the
operation  of  any  provision  of  this  Agreement  shall  not be  construed  as
preventing the occurrence of an Event of Default.

      Section 12. Notice of Acceleration, Enforcement Action.
                  ------------------------------------------

            (a) Each Second Lien Lender agrees that in the event any event of
default under the Second Lien Credit Agreement (or the Second Lien Notes, if
any) (a "Second Lien Event of Default") shall occur, and as a result thereof,
any Second Lien Lender or the Second Lien Administrative Agent or other
representative of such Second Lien Lender accelerates maturity of the Second
Lien Notes, if any, then such Second Lien Lender or the Second Lien
Administrative Agent or other representative shall give prompt (and in any event
within three (3) Business Days) notice thereof in writing to the holders of the
Senior Secured Indebtedness or the Senior Secured Indebtedness Representative.
Neither of the Borrowers nor any Subsidiary may pay any Second Lien Notes until
ten (10) Business Days after the Senior Secured Lenders or Senior Secured
Indebtedness Representative, the Second Lien Administrative Agent and the
Collateral Agent receives the notice described above and, after that ten (10)
Business Day period, may pay any Second Lien Notes, and the Second Lien Lenders
may receive or collect such payment, only if the provisions of this Agreement do
not prohibit such payment at that time.

                                       21
<PAGE>

            (b) Each Second Lien Lender agrees that in the event any Second Lien
Event of Default shall occur, and as a result thereof, any Second Lien Lender or
the Second Lien Administrative Agent or other representative of such Second Lien
Lender intends to commence any Enforcement Action, then such Second Lien Lender
or the Second Lien Administrative Agent or other representative shall first
deliver notice thereof in writing to the Senior Secured Indebtedness
Representative and the Collateral Agent both (i) not less than ten (10) days
prior to taking any such Enforcement Action, and (ii) one (1) Business Day after
such Enforcement Action is taken.

      Section 13. Reinstatement. The provisions of this Agreement shall remain
in force and effect until the indefeasible payment in full in cash of all Senior
Secured Indebtedness and all amounts payable under any Swap Agreement and the
termination of all commitments of any holder of the Senior Secured Indebtedness
to make loans or extensions of credit, and expiration or termination of all
letters of credit issued by any holder of the Senior Secured Indebtedness. To
the extent any payment of or distribution in respect of the Senior Secured
Indebtedness or any amount payable under any Swap Agreement (whether by or on
behalf of either of the Borrowers or any of their Subsidiaries, as proceeds of
security or enforcement of any right of set off or otherwise) is declared to be
fraudulent or preferential, set aside or required to be paid to the Borrowers or
any of their Subsidiaries or any receiver, trustee in bankruptcy, liquidating
trustee, agent or other similar person under any bankruptcy, insolvency,
receivership, fraudulent conveyance or similar law, then if such payment or
distribution is recovered by, or paid over to, the Borrower or any Subsidiary or
such receiver, trustee in bankruptcy, liquidating trustee, agent or other
similar Person, the Senior Secured Indebtedness or part thereof and/or payment
obligation under such Swap Agreement originally intended to be satisfied shall
be deemed to be reinstated and outstanding as if such payment has not occurred
and the provisions of this Agreement shall continue to be applicable in respect
of said reinstated Senior Secured Indebtedness or payment obligation under such
Swap Agreement.

      Section 14. Rights of Holders of the Senior Secured Indebtedness and Swap
Counterparties. The holders of the Senior Secured Indebtedness may, at any time
and from time to time subject to the terms of the Senior Secured Indebtedness,
without the consent of or notice to the Second Lien Lenders or the Second Lien
Administrative Agent or other representative of the Second Lien Lenders, without
incurring responsibility to the Second Lien Lenders and without impairing or

            (c) No amendment of this Agreement or the definitions used in this

in writing and made with the prior written consent of the Required Senior
Secured Revolving Lenders or the Senior Secured Indebtedness Representative

            (d) No amendment of this Agreement or the definitions used in this

            (e) No amendment of this Agreement or the definitions used in this

      Section 16. Identity of Second Lien Lenders for Notice Purposes. For
purposes of any notice required or permitted to be given hereunder by the

the Collateral Agent, the holders of the Senior Secured Indebtedness and the
Senior Secured Indebtedness Representative shall be entitled to rely,
conclusively, on the identity and address of each Second Lien Lender as set
forth in the Second Lien Loan Agreement or as otherwise set forth in the most
recent notice received by the Senior

                                       23
<PAGE>

Secured  Indebtedness  Representative from a Second Lien Lender referring to the
Second Lien Loan Agreement for purposes of providing the identity and address of
each Second Lien Lender. The Second Lien Lenders agree that any notices required
to be given to the Second  Lien  Lenders  shall be  effective  if such notice is
given to the Second Lien  Administrative  Agent or other  representative  of the
Second  Lien  Lenders.   For  so  long  as  the  Subordinated   Obligations  are
outstanding, the Second Lien Lenders agree to designate and maintain an agent or
other representative for such purposes.

      Section 17. Liens.
                  -----

            (a) All Liens granted by either of the Borrowers, or any Guarantor,
which at any time secure the Second Lien Credit Agreement, any Second Lien Note
or any other Second Lien Loan Document are hereby made, and will at all times
prior to the full payment or discharge of the Senior Secured Indebtedness and
the payment in full of all amounts payable and termination of all of the Swap
Agreements be, subject and subordinate to all Liens granted by either of the
Borrowers or any Guarantor which at any time secure the Senior Secured
Indebtedness and amounts payable under Swap Agreements, which subordination
shall be effective whether or not all such Liens securing Senior Secured
Indebtedness and amounts payable under Swap Agreements have been properly
recorded, filed and otherwise perfected prior to all such Liens securing any
Second Lien Note and regardless of the relative priority of such Liens as
determined without regard to this Agreement. The mortgages included in the
Senior Secured Loan Documents do (and other mortgages, security agreements and
similar Senior Secured Loan Documents may) describe the indebtedness secured
thereby in a manner which might include indebtedness (including amounts payable
under Swap Agreements) other than the Senior Secured Indebtedness. For so long
as any Second Lien Note is outstanding, as between the Second Lien Lenders and
the holders of the Senior Secured Indebtedness and any Swap Counterparty, only
the Senior Secured Indebtedness and amounts payable under the Swap Agreements
shall be deemed to be secured by any Liens granted under the Senior Secured Loan
Documents.

            (b) Each Second Lien Lender agrees that it will not initiate, join
in or prosecute any claim, action or other proceeding challenging the validity
or enforceability of the Senior Secured Indebtedness or any Swap Agreement or
the Liens securing the Senior Secured Indebtedness and amounts payable under any
Swap Agreement.

      Section 18. Purchase of the Senior Indebtedness.
                  -----------------------------------

      In the event that (i) a Payment Blockage Period or a Non-Payment Blockage
Period shall have commenced pursuant to Section 6 or 7 hereof, respectively, and
shall be continuing, or (ii) an event of default under the Second Lien Loan
Documents shall have occurred and is continuing, regardless of whether any
notice has been sent pursuant to Section 12 hereof, or (iii) if any Insolvency
Proceeding has been commenced and is continuing, the Second Lien Lenders may, in
their sole and absolute discretion, purchase all, but not less than all, of the
Senior Secured Indebtedness from the Senior Secured Lenders by sending a notice
to buy the Senior Secured Indebtedness and Liens securing same from the Senior
Secured Lenders upon the following terms and conditions: (w) the Second Lien
Lenders shall give written notice to the Senior Secured Lenders, informing the
Senior Secured Lenders of the Second Lien Lenders

election to purchase the Senior  Secured  Indebtedness  and Liens  securing same
(the  purchase  hereinafter  called  a  "Purchase"  and any  such  notice  being
hereinafter called a "Purchase Notice"),  (x) the Second Lien Lenders shall have
forty-five  (45) days from the date of the  Purchase  Notice to  consummate  the
purchase of the Senior Secured  Indebtedness  for an amount equal to 100% of the
outstanding  Senior  Secured   Indebtedness   (including,   without  limitation,
principal,  interest,  fees, and expenses (reimbursable under the Senior Secured
Loan Documents)  outstanding on the date of the purchase,  (y) if based upon the
receipt of a Payment Default Notice or a Non-Payment Default Notice, as the case
may be, said Purchase shall not occur (at Senior Secured  Lenders'  election) if
all events of default  that  precipitated  the  delivery of the Payment  Default
Notice or the Non-Payment  Default Notice have been waived or cured prior to the
consummation  of the  Purchase,  and (z) upon receipt of payment with respect to
the Purchase as described  above,  the Senior  Secured  Lenders shall execute an
assignment of the Senior  Secured  Indebtedness  and Liens  securing same to the
Second Lien  Lenders  without  recourse and without  representation  or warranty
(either  express or implied),  other than to the effect that the Senior  Secured
Lenders at the closing of the Purchase have sold or assigned the Senior  Secured
Indebtedness  and Liens  securing same to the Second Lien Lenders and the amount
of the Senior Secured Indebtedness.  Contemporaneously  with the consummation of
the Purchase, the Borrowers and the Guarantors shall acknowledge such assignment
and shall do all things necessary to give full force and effect thereto.

                  ------

agrees to take any and all additional actions and execute, deliver, file and/or
record any and all additional agreements, documents and instruments as may be
necessary or as Senior Secured Creditor may from time to time reasonably request

<PAGE>

      Section 26. Severability. Whenever possible, each provision of this
Agreement shall be interpreted in such a manner as to be effective and valid
under applicable law, but if any provision of this Agreement shall be prohibited
by or invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of such provisions or the remaining provisions of this Agreement.

      Section 27. Equitable Remedies. Each party to this Agreement acknowledges
that the breach by it of any of the provisions of this Agreement is likely to
cause irreparable damage to the other party. Therefore, the relief to which any
party shall be entitled in the event of any such breach or threatened breach
shall include, but not be limited to, a mandatory injunction for specific
performance, injunctive or other judicial relief to prevent a violation of any
of the provisions of this Agreement, damages and any other relief to which it
may be entitled at law or in equity.

      Section 28. Revival. Second Lien Creditor further agrees that, to the
extent that any Loan Party makes a payment or payments to Senior Secured
Creditor, which payment or payments or any parts thereof are subsequently
invalidated, avoided, declared to be fraudulent or preferential, set aside, or
required to be repaid to a debtor in possession, a trustee, a receiver or any
other party under Title 11, United States Code, any state or federal law, common
law, or equitable cause, then to the extent of such payment or repayment, the
obligation or part thereof intended to be satisfied shall be revived and
continued in full force and effect as a part of the obligations of the Loan
Parties under the Senior Secured Indebtedness as if such payment had not been
made, and shall be subject in all respects to the provisions in favor of Senior
Secured Creditor hereunder.

      Section 29. Exculpation Provisions. Each of the parties hereto
specifically agrees that it has a duty to read this Agreement and the Security

of this Agreement and the Security Instruments; that it has in fact read this
Agreement and is fully informed and has full notice and knowledge of the terms,
conditions, and effects of this Agreement; that it has independently made its
own analysis of the financial condition of the Borrower and the Guarantors and
their assets including, without limitation, their Collateral; that it has been
represented by independent legal counsel of its choice throughout the
negotiations preceding its execution of this Agreement and the Security
Instruments; and has received the advice of its attorney in entering into this
Agreement and the Security Instruments; and that it recognizes that certain of
the terms of this Agreement and the Security Instruments result in one party
assuming the liability inherent in some aspects of the transaction and relieving
the other party of its responsibility for such liability. Each party hereto
agrees and covenants that it will not contest the validity or enforceability of
any exculpatory provision of this Agreement and the Security Instruments on the
basis that the party had no notice or knowledge of such provision or that the
provision is not "conspicuous."

      Section 30. WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN CONNECTION
WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED
BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE FEDERAL AND
STATE LAWS TO APPLY, THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A
JUDGE APPLYING SUCH APPLICABLE LAWS. THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL
BY

<PAGE>

JURY IN ANY ACTION,  SUIT OR PROCEEDING  BROUGHT TO ENFORCE OR DEFEND ANY RIGHTS
OR REMEDIES UNDER THIS AGREEMENT.

      Section 31. NO ORAL AGREEMENTS. THIS AGREEMENT AND THE LOAN DOCUMENTS
EMBODY THE ENTIRE AGREEMENT AND UNDERSTANDING BETWEEN THE PARTIES AND SUPERSEDE
ALL OTHER AGREEMENTS AND UNDERSTANDINGS BETWEEN SUCH PARTIES RELATING TO THE
SUBJECT MATTER HEREOF AND THEREOF. THIS AGREEMENT AND THE LOAN DOCUMENTS
REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.
THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

      Section 32. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. Signatures given by
facsimile or other electronic transmission shall be binding and effective as
originals.
