          remedy  against the  Borrower,  any other  Obligor or any other Person
          under the provisions of either of the Credit Agreements, any Note, any
          other Loan Document or otherwise, or

               (ii) to exercise any right or remedy against any other  guarantor
          of, or collateral  securing,  any  Obligations  of the Borrower or any

     Obligor,

          (d)  any  reduction,  limitation,  impairment  or  termination  of any
     Obligations of the Borrower or any other Obligor for any reason,  including
     any claim of waiver,  release,  surrender,  alteration or  compromise,  and
     shall not be subject  to (and the  Borrower  hereby  waives any right to or
     claim of) any defense or setoff,  counterclaim,  recoupment or  termination
     whatsoever  by  reason  of  the  invalidity,  illegality,   nongenuineness,
     irregularity,  compromise,  unenforceability  of,  or any  other  event  or
     occurrence affecting, any Obligations of the Borrower, any other Obligor or
     otherwise,

          (e) any amendment to, rescission, waiver, or other modification of, or
     any  consent to  departure  from,  any of the terms of either of the Credit
     Agreements, any Note or any other Loan Document,

          (f) any addition,  exchange,  release,  surrender or non-perfection of
     any collateral (including the Collateral), or any amendment to or waiver or
     release of or addition to or consent to departure  from any  guaranty,  for
     any of the Obligations, or

          (g) any other circumstances which might otherwise constitute a defense
     available to, or a legal or equitable discharge of, the Borrower, any other
     Obligor, any surety or any guarantor.

     SECTION 2.7.  Subrogation,  etc. The Borrower  will not exercise any rights
which it may acquire by reason of any payment made hereunder,  whether by way of
subrogation,  reimbursement or otherwise until the prior indefeasible payment in
full, in cash, of all  Obligations of the Borrower and each other  Obligor.  Any
amount paid to the  Borrower on account of any payment made  hereunder  prior to
the payment in full of all  Obligations  of the Borrower and each other  Obligor
shall be held in trust for the benefit of the Lender  Parties and each holder of
a Note and shall  immediately be paid to the Lender Parties and each holder of a
Note and credited and applied  against the  Obligations of the Borrower and each
other Obligor, whether matured or unmatured, in accordance with the terms of the
Credit Agreements; provided, however, that if

          (a) the  Borrower  has made  payment  to the Lender  Parties  and each
     holder of a Note of all or any part of the  Obligations  of the Borrower or
     any other Obligor, and

          (b) all  Obligations  of the Borrower and each other Obligor have been
     indefeasibly  paid  in  full,  in  cash,  and  all  Commitments  have  been
     permanently terminated,

each  Lender  Party and each  holder of a Note agrees  that,  at the  Borrower's
request,  the Lender  Parties  and the  holders of the Notes  will  execute  and
deliver to the  Borrower  appropriate  documents  (without  recourse and without
representation  or  warranty  and at the sole  cost  and  expense  of  Borrower)
necessary to evidence the transfer by subrogation to the Borrower of an interest
in the  Obligations  of the Borrower and each other Obligor  resulting from such
payment by the Borrower.  In furtherance  of the  foregoing,  for so long as any
Obligations or Commitments remain  outstanding,  the Borrower shall refrain from
taking any action or commencing any proceeding against the Borrower or any other
Obligor (or its successors or assigns,  whether in connection  with a bankruptcy
proceeding  or  otherwise)  to recover any  amounts in respect of payments  made
under this Pledge Agreement to any Lender Party or any holder of a Note.

          SECTION 2.8. Waiver of Subrogation. Until such time as the Obligations
     have been indefeasibly paid in full, in cash, and the Commitments have been
     terminated,  the  Borrower  hereby  irrevocably  waives  any claim or other
     rights  which it may now or hereafter  acquire  against the Borrower or any
     other  Obligor  that  arise from the  existence,  payment,  performance  or
     enforcement of the Borrower's  obligations  under this Pledge  Agreement or
     any other Loan Document, including any right of subrogation, reimbursement,
     exoneration,  or indemnification,  any right to participate in any claim or
     remedy of the Lender  Parties  against the Borrower or any other Obligor or
     any collateral  which the Agent now has or hereafter  acquires,  whether or
     not such  claim,  remedy or right  arises  in  equity,  or under  contract,
     statute or common  law,  including  the right to take or  receive  from the
     Borrower or any other  Obligor,  directly or  indirectly,  in cash or other
     property or by set-off or in any manner,  payment or security on account of
     such claim or other rights.  If any amount shall be paid to the Borrower in
     violation of the preceding sentence and the Obligations shall not have been
     indefeasibly  paid in full,  in  cash,  and the  Commitments  have not been
     terminated,  such amount  shall be deemed to have been paid to the Borrower
     for the benefit of, and held in trust for,  the Lender  Parties,  and shall
     forthwith be paid to the Lender Parties to be credited and applied upon the
     Obligations,  whether matured or unmatured.  The Borrower acknowledges that
     it  will  receive   direct  and  indirect   benefits   from  the  financing
     arrangements  contemplated by the Credit Agreements and that the waiver set
     forth in this Section is knowingly made in contemplation of such benefits.

security interest.

     SECTION  3.1.3  As to  Pledged  Interests  . In the  case  of  any  Pledged
Interests  constituting such Collateral,  all of such Pledged Interests are duly

of  the  Borrower  in  the  Pledged  Interests  Issuers  are  represented  by  a

from time to time,  at the expense of the  Borrower,  the Borrower will promptly
execute and deliver all further  instruments,  and take all further action, that

(including  any of the Pledged  Interests ) constituting  Collateral;  provided,

in the  custody  and  preservation  of any of the  Collateral,  if it takes such
action for that purpose as the Borrower  reasonably requests in writing at times
other  than upon the  occurrence  and  during  the  continuance  of any Event of
Default,  but failure of the Agent to comply  with any such  request at any time
shall not in itself be deemed a failure to exercise reasonable care.

                                   ARTICLE VI
                                    REMEDIES

     SECTION 6.1. Certain Remedies.  If any Event of Default shall have occurred
and be continuing:

          (a) The Agent may exercise in respect of the  Collateral,  in addition
     to other rights and remedies provided for herein or otherwise  available to
     it, all the rights and  remedies  of a secured  party on default  under the
     U.C.C.  (whether or not the U.C.C.  applies to the affected Collateral) and
     also may, without notice except as specified below,  sell the Collateral or
     any part thereof in one or more parcels at public or private  sale,  at any
     of the  Agent's  offices or  elsewhere,  for cash,  on credit or for future
     delivery,  and upon such  other  terms as the  Agent may deem  commercially
     reasonable. The Borrower agrees that, to the extent notice of sale shall be
     required  by law, at least ten days'  prior  notice to the  Borrower of the
     time and place of any public sale or the time after which any private  sale
     is to be made shall constitute reasonable notification. The Agent shall not
     be obligated to make any sale of  Collateral  regardless  of notice of sale
     having  been given.  The Agent may adjourn any public or private  sale from
     time to time by announcement at the time and place fixed therefor, and such
     sale may, without further notice, be made at the time and place to which it
     was so adjourned.

          (b) The Agent may

               (i) transfer all or any part of the  Collateral  into the name of
          the  Agent  or its  nominee,  with or  without  disclosing  that  such
          Collateral is subject to the lien and security interest hereunder,

               (ii) notify the parties  obligated  on any of the  Collateral  to
          make  payment  to  the  Agent  of any  amount  due  or to  become  due
          thereunder,

               (iii)enforce  collection  of any of the  Collateral  by  suit  or
          otherwise, and surrender, release or exchange all or any part thereof,
          or compromise or extend or renew for any period (whether or not longer
          than the original  period) any  obligations of any nature of any party
          with respect thereto,

               (iv)  endorse  any  checks,  drafts,  or  other  writings  in the
          Borrower's name to allow collection of the Collateral,

               (v) take control of any proceeds of the Collateral, and

               (vi)  execute  (in the name,  place  and  stead of the  Borrower)
          endorsements,  assignments,  stock  powers  and other  instruments  of
          conveyance or transfer with respect to all or any of the Collateral.

     SECTION 6.2.  Securities Laws. If the Agent shall determine to exercise its
right to sell all or any of the Collateral pursuant to Section 6.1, the Borrower
agrees that, upon request of the Agent, the Borrower will, at its own expense:

          (a) execute and deliver,  and cause each Pledged  Interests  Issuer of
     the Collateral  contemplated  to be sold and the members thereof to execute
     and deliver, all such instruments and documents, and do or cause to be done
     all such other acts and things,  as may be necessary  or, in the opinion of
     the Agent,  advisable to register such  Collateral  under the provisions of
     the Securities  Act of 1933, as from time to time amended (the  "Securities
     Act"), and to cause the registration  statement  relating thereto to become
     effective  and to remain  effective  for such  period as  prospectuses  are
     required by law to be furnished, and to make all amendments and supplements
     thereto and to the related  prospectus  which, in the opinion of the Agent,
     are necessary or advisable,  all in conformity with the requirements of the
     Securities Act and the rules and regulations of the Securities and Exchange
     Commission applicable thereto;

          (b) use its best  efforts to qualify  the  Collateral  under the state
     securities  or "Blue  Sky" laws and to obtain  all  necessary  governmental
     approvals for the sale of the Collateral, as requested by the Agent;

          (c) cause each such issuer to make available to its security  holders,
     as soon as  practicable,  an  earnings  statement  that  will  satisfy  the
     provisions of Section 11(a) of the Securities Act; and

          (d) do or cause to be done all such  other  acts and  things as may be
     necessary to make such sale of the Collateral or any part thereof valid and
     binding and in compliance with applicable law.

     SECTION 6.3. Compliance with Restrictions.  The Borrower agrees that in any
sale of any of the  Collateral  whenever an Event of Default shall have occurred
and be continuing,  the Agent is hereby authorized to comply with any limitation
or restriction  in connection  with such sale as it may be advised by counsel is
necessary  in  order  to  avoid  any  violation  of  applicable  law  (including
compliance  with such  procedures  as may  restrict  the  number of  prospective
bidders and  purchasers,  require that such  prospective  bidders and purchasers
have  certain   qualifications,   and  restrict  such  prospective  bidders  and
purchasers to persons who will  represent and agree that they are purchasing for
their own  account for  investment  and not with a view to the  distribution  or
resale of such  Collateral),  or in order to obtain any required approval of the
sale or of the purchaser by any governmental  regulatory  authority or official,
and the Borrower  further agrees that such  compliance  shall not result in such
sale  being  considered  or  deemed  not to have  been  made  in a  commercially
reasonable manner, nor shall the Agent be liable nor accountable to the Borrower
for any discount  allowed by the reason of the fact that such Collateral is sold
in compliance with any such limitation or restriction.

     SECTION 6.4.  Application  of Proceeds.  All cash proceeds  received by the
Agent in respect of any sale of, collection from, or other realization upon, all
or any part of the  Collateral  may  thereafter be applied (after payment of any
amounts  payable to the Agent  pursuant to Article III of the Credit  Agreements
and Section  6.4) in whole or in part by the Agent  against,  all or any part of
the Secured Obligations in such order as the Agent shall elect.

     Any surplus of such cash or cash  proceeds  held by the Agent and remaining
after payment in full of all the Secured Obligations, and the termination of all
Commitments, shall be paid over to the Borrower or to whomsoever may be lawfully
entitled to receive such surplus.

     SECTION 6.5.  Indemnity and Expenses.  The Borrower hereby  indemnifies and
holds  harmless  the Agent from and  against  any and all  claims,  losses,  and
liabilities  arising out of or resulting from this Pledge  Agreement  (including
enforcement of this Pledge  Agreement),  except claims,  losses,  or liabilities
resulting from the Agent's gross negligence or willful misconduct.  Upon demand,
the  Borrower  will  pay to the  Agent  the  amount  of any and  all  reasonable
expenses,  including the reasonable fees and disbursements of its counsel and of
any experts and agents, which the Agent may incur in connection with:

          (a) the administration of this Pledge Agreement, the Credit Agreements
     and each other Loan Document;

          (b) the custody,  preservation,  use, or operation of, or the sale of,
     collection from, or other realization upon, any of the Collateral;

          (c) the  exercise  or  enforcement  of any of the  rights of the Agent
     hereunder; or

          (d) the  failure by the  Borrower  to  perform  or observe  any of the
     provisions hereof.

                                  ARTICLE VII
                            MISCELLANEOUS PROVISIONS

     SECTION  7.1.  Loan  Document.  This Pledge  Agreement  is a Loan  Document
executed pursuant to the Credit Agreements and shall (unless otherwise expressly
indicated herein) be construed,  administered and applied in accordance with the
terms and provisions thereof.

     SECTION 7.2. Amendments, etc. No amendment to or waiver of any provision of
this Pledge  Agreement  nor consent to any  departure by the  Borrower  herefrom
shall in any event be  effective  unless the same shall be in writing and signed
by the Agent,  and then such waiver or consent  shall be  effective  only in the
specific instance and for the specific purpose for which it is given.

     SECTION 7.3. Protection of Collateral.  The Agent may from time to time, at
its option,  perform any act which the Borrower agrees  hereunder to perform and
which the Borrower shall fail to perform after being  requested in writing so to
perform  (it  being  understood  that no such  request  need be given  after the
occurrence and during the  continuance of an Event of Default) and the Agent may
from time to time  take any  other  action  which  the  Agent  reasonably  deems
necessary  for  the  maintenance,  preservation  or  protection  of  any  of the
Collateral or of its security interest therein.

     SECTION 7.4.  Addresses for Notices.  All notices and other  communications
provided for hereunder shall be in writing (including telegraphic communication)
and, if to the Borrower, mailed or telegraphed or delivered to it at the address
set forth below its signature  hereto,  if to the Agent,  mailed or delivered to
it,  addressed  to it at the address of the Agent  specified  in the 2002 Credit
Agreement or, as to either  party,  at such other address as shall be designated
by such party in a written  notice to each other party  complying as to delivery
with the terms of this Section. All such notices and other communications shall,
when mailed or  telegraphed,  respectively,  be effective  when deposited in the
mails  or  delivered  to  the  telegraph  company,  respectively,  addressed  as
aforesaid.

     SECTION  7.5.  Section  Captions.  Section  captions  used in  this  Pledge
Agreement  are for  convenience  of  reference  only,  and shall not  affect the
construction of this Pledge Agreement.

     SECTION 7.6. Severability.  Wherever possible each provision of this Pledge
Agreement shall be interpreted in such manner as to be effective and valid under
applicable  law,  but if  any  provision  of  this  Pledge  Agreement  shall  be
prohibited by or invalid under such law, such provision  shall be ineffective to
the extent of such prohibition or invalidity, without invalidating the remainder
of such provision or the remaining provisions of this Pledge Agreement.

     SECTION 7.7.  Governing Law, Entire  Agreement,  etc. THIS PLEDGE AGREEMENT
SHALL BE GOVERNED BY AND CONSTRUED IN  ACCORDANCE  WITH THE INTERNAL LAWS OF THE
STATE OF NEW YORK,  EXCEPT TO THE EXTENT THAT THE VALIDITY OR  PERFECTION OF THE
SECURITY INTEREST HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR
COLLATERAL  ARE GOVERNED BY THE LAWS OF A  JURISDICTION  OTHER THAN THE STATE OF
NEW YORK.  THIS PLEDGE  AGREEMENT AND THE OTHER LOAN  DOCUMENTS  CONSTITUTE  THE
ENTIRE UNDERSTANDING AMONG THE PARTIES HERETO WITH RESPECT TO THE SUBJECT MATTER
HEREOF  AND  SUPERSEDE  ANY PRIOR  AGREEMENTS,  WRITTEN  OR ORAL,  WITH  RESPECT
THERETO.

     SECTION 7.8. Forum  Selection and Consent to  Jurisdiction.  ANY LITIGATION
BASED HEREON,  OR ARISING OUT OF,  UNDER,  OR IN  CONNECTION  WITH,  THIS PLEDGE
AGREEMENT,  OR ANY COURSE OF  CONDUCT,  COURSE OF DEALING,  STATEMENTS  (WHETHER
VERBAL OR WRITTEN)  OR ACTIONS OF THE LENDER  PARTIES OR THE  BORROWER  SHALL BE
BROUGHT AND MAINTAINED  EXCLUSIVELY IN THE COURTS OF THE STATE OF NEW YORK OR IN
THE  UNITED  STATES  DISTRICT  COURT  FOR THE  SOUTHERN  DISTRICT  OF NEW  YORK;
PROVIDED,  HOWEVER,  THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR
OTHER  PROPERTY  MAY BE  BROUGHT,  AT THE AGENT'S  OPTION,  IN THE COURTS OF ANY
JURISDICTION  WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE FOUND. THE BORROWER
HEREBY  EXPRESSLY AND IRREVOCABLY  SUBMITS TO THE  JURISDICTION OF THE COURTS OF
THE STATE OF NEW YORK AND OF THE UNITED STATES  DISTRICT  COURT FOR THE SOUTHERN
DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH  LITIGATION  AS SET FORTH ABOVE
AND  IRREVOCABLY  AGREES  TO BE  BOUND  BY  ANY  JUDGMENT  RENDERED  THEREBY  IN
CONNECTION WITH SUCH LITIGATION.  THE BORROWER FURTHER  IRREVOCABLY  CONSENTS TO
THE  SERVICE OF PROCESS BY  REGISTERED  MAIL,  POSTAGE  PREPAID,  OR BY PERSONAL
SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK. THE BORROWER  HEREBY  EXPRESSLY
AND IRREVOCABLY  WAIVES,  TO THE FULLEST EXTENT  PERMITTED BY LAW, ANY OBJECTION
WHICH  IT MAY HAVE OR  HEREAFTER  MAY  HAVE TO THE  LAYING  OF VENUE OF ANY SUCH
LITIGATION  BROUGHT IN ANY SUCH COURT  REFERRED  TO ABOVE AND ANY CLAIM THAT ANY
SUCH  LITIGATION HAS BEEN BROUGHT IN AN  INCONVENIENT  FORUM. TO THE EXTENT THAT
THE BORROWER HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM  JURISDICTION OF ANY
COURT OR FROM ANY LEGAL PROCESS (WHETHER  THROUGH SERVICE OR NOTICE,  ATTACHMENT
PRIOR TO JUDGMENT,  ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO
ITSELF OR ITS PROPERTY,  THE BORROWER HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN
RESPECT OF ITS OBLIGATIONS UNDER THIS PLEDGE AGREEMENT.

     SECTION  7.9.  Waiver of Jury Trial.  THE LENDER  PARTIES AND THE  BORROWER
HEREBY KNOWINGLY,  VOLUNTARILY AND INTENTIONALLY  WAIVE ANY RIGHTS THEY MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF,
UNDER, OR IN CONNECTION WITH, THIS PLEDGE  AGREEMENT,  OR ANY COURSE OF CONDUCT,
COURSE OF  DEALING,  STATEMENTS  (WHETHER  VERBAL OR  WRITTEN) OR ACTIONS OF THE
LENDER PARTIES OR THE BORROWER. THE BORROWER ACKNOWLEDGES AND AGREES THAT IT HAS
RECEIVED FULL AND  SUFFICIENT  CONSIDERATION  FOR THIS PROVISION (AND EACH OTHER
PROVISION  OF EACH  OTHER  LOAN  DOCUMENT  TO WHICH IT IS A PARTY) AND THAT THIS
PROVISION IS A MATERIAL  INDUCEMENT  FOR THE LENDER  PARTIES  ENTERING  INTO THE
CREDIT AGREEMENTS AND EACH SUCH OTHER LOAN DOCUMENT.






     IN WITNESS WHEREOF, the parties hereto have caused this Pledge Agreement to
be duly  executed and  delivered by their  respective  officers  thereunto  duly
authorized as of the day and year first above written.
