     forth in Section 3.2(a)(i), and (2) if such Partnership Interest or
     Limited Liability Company Interest is not represented by a
     certificate, the procedure set forth in Section 3.2(a)(ii);

        (v)  with respect to any Note, physical delivery of such Note
     to the Pledgee, endorsed to the Pledgee or endorsed in blank; and

       (vi)  after an Event of Default has occurred and is continuing,
     with respect to cash, to the extent not otherwise provided in the
     Security Agreement, (i) establishment by the Pledgee of a cash
     account in the name of such Pledgor over which the Pledgee shall
     have exclusive and absolute control and dominion (and no
     withdrawals or transfers may be made therefrom by any Person except
     with the prior written consent of the Pledgee) and (ii) deposit of
     such cash in such cash account.



          (b)  In addition to the actions required to be taken pursuant
to preceding Section 3.2(a), each Pledgor shall take the following
additional actions with respect to the Securities and Collateral (as
defined below):

        (i)  with respect to all Collateral of such Pledgor whereby or
     with respect to which the Pledgee may obtain "control" thereof
     within the meaning of Section 8-106 of the UCC (or under any
     provision of the UCC as same may be amended or supplemented from
     time to time, or under the laws of any relevant State other than
     the State of New York), the respective Pledgor shall take all
     actions as may be requested from time to time by the Pledgee so
     that "control" of such Collateral is obtained and at all times held
     by the Pledgee; and

       (ii)  each Pledgor shall from time to time cause appropriate
     financing statements (on Form UCC-1 or other appropriate form)
     under the Uniform Commercial Code as in effect in the various
     relevant States, on form covering all Collateral hereunder (with
     the form of such financing statements to be satisfactory to the
     Pledgee), to be filed in the relevant filing offices so that at all
     times the Pledgee has a security interest in all Investment
     Property and other Collateral which is perfected by the filing of
     such financing statements (in each case to the maximum extent
     perfection by filing may be obtained under the laws of the relevant
     States, including, without limitation, Section 9-115(4)(b) of the
     UCC).

          3.3  Subsequently Acquired Collateral.  If any Pledgor shall
acquire (by purchase, stock dividend or otherwise) any additional
Collateral at any time or from time to time after the date hereof, such
Collateral shall automatically (and without any further action being
required to be taken) be subject to the pledge and security interests
created pursuant to Section 3.1 and, furthermore, such Pledgor will
promptly thereafter take (or cause to be taken) all action with respect
to such Collateral in accordance with the procedures set forth in
Section 3.2, and will promptly thereafter deliver to the Pledgee (i) a
certificate executed by a principal executive officer of such Pledgor
describing such Collateral and certifying that the same has been duly
pledged in favor of the Pledgee (for the benefit of the Secured
Creditors) hereunder and (ii) supplements to Annexes A through F hereto
as are necessary to cause such annexes to be complete and accurate at
such time.  Without limiting the foregoing, each Pledgor shall be
required to pledge hereunder any shares of stock at any time and from
time to time after the date hereof acquired by such Pledgor of any
Foreign Corporation, provided that any pledge of the Voting Stock of any
Foreign Corporation shall be subject to the provisions of clause (x) of
the proviso to Section 3.1 hereof to the extent same is then applicable.

          3.4  Transfer Taxes.  Each pledge of Collateral under Section
3.1 or Section 3.3 shall be accompanied by any transfer tax stamps
required in connection with the pledge of such Collateral.



          3.5  Certain Representations and Warranties Regarding the
Collateral.  Each Pledgor represents and warrants that on the date
hereof (i) each Subsidiary of such Pledgor, and the direct ownership
thereof, is listed in Annex A hereto; (ii) the Stock held by such
Pledgor consists of the number and type of shares of the stock of the
corporations as described in Annex B hereto; (iii) such Stock
constitutes that percentage of the issued and outstanding capital stock
of the issuing corporation as is set forth in Annex B hereto; (iv) the
Notes held by such Pledgor consist of the promissory notes described in
Annex C hereto where such Pledgor is listed as the lender; (v) the
Limited Liability Company Interests held by such Pledgor consist of the
number and type of interests of the Persons described in Annex D hereto;
(vi) each such Limited Liability Company Interest constitutes that
percentage of the issued and outstanding equity interest of the issuing
Person as set forth in Annex D hereto; (vii) the Partnership Interests
held by such Pledgor consist of the number and type of interests of the
Persons described in Annex E hereto; (viii) each such Partnership
Interest constitutes that percentage or portion of the entire
partnership interest of the Partnership as set forth in Annex E hereto;
(ix) the Pledgor has complied with the respective procedure set forth in
Section 3.2(a) with respect to each item of Collateral described in
Annexes A through E hereto; and (x) on the date hereof, such Pledgor
owns no other Securities, Limited Liability Company Interests or
Partnership Interests.

          4.  APPOINTMENT OF SUB-AGENTS; ENDORSEMENTS, ETC.  The Pledgee
shall have the right to appoint one or more sub-agents for the purpose
of retaining physical possession of the Collateral, which may be held
(in the discretion of the Pledgee) in the name of the relevant Pledgor,
endorsed or assigned in blank or in favor of the Pledgee or any nominee
or nominees of the Pledgee or a sub-agent appointed by the Pledgee.

          5.  VOTING, ETC., WHILE NO EVENT OF DEFAULT.  Unless and until
there shall have occurred and be continuing an Event of Default or a
Default under Section 9.01 or 9.05 of the Credit Agreement (each such
Default, a "Specified Default"), each Pledgor shall be entitled to
exercise all voting rights attaching to any and all Collateral owned by
it, and to give consents, waivers or ratifications in respect thereof,
provided that no vote shall be cast or any consent, waiver or
ratification given or any action taken which would violate, result in
breach of any covenant contained in, or be inconsistent with, any of the
terms of this Agreement, the Credit Agreement, any other Credit Document
or any Interest Rate Protection Agreement or Other Hedging Agreement
(collectively, the "Secured Debt Agreements"), or which would have the
effect of impairing the value of the Collateral or any part thereof or
the position or interests of the Pledgee or any other Secured Creditor
therein, except to the extent such violation, inconsistency or
impairment shall be waived in accordance with the terms of Section 22
hereof.  All such rights of a Pledgor to vote and to give consents,
waivers and ratifications shall cease in case an Event of Default or a
Specified Default shall occur and be continuing and Section 7 hereof
shall become applicable.



          6.  DIVIDENDS AND OTHER DISTRIBUTIONS.  Unless and until an
Event of Default or a Specified Default shall have occurred and be
continuing, all cash dividends, cash distributions, cash Proceeds and
other cash amounts payable in respect of the Collateral shall be paid to
the respective Pledgor; provided, that all cash dividends payable in
respect of the Pledged Stock which are determined by the Pledgee to
represent in whole or in part an extraordinary, liquidating or other
distribution in return of capital shall be paid, to the extent so
determined to represent an extraordinary, liquidating or other
distribution in return of capital, to the Pledgee and retained by it as
part of the Collateral.  Subject to Section 3.2 hereof, the Pledgee
shall be entitled to receive directly, and to retain as part of the
Collateral:

        (i)  all other or additional stock, notes, limited liability
     company interests, partnership interests, instruments or other
     securities or property (including, but not limited to, cash
     dividends other than as set forth above) paid or distributed by way
     of dividend or otherwise in respect of the Collateral;

       (ii)  all other or additional stock, notes, limited liability
     company interests, partnership interests, instruments or other
     securities or property (including, but not limited to, cash) paid
     or distributed in respect of the Collateral by way of stock-split,
     spin-off, split-up, reclassification, combination of shares or
     similar rearrangement; and

      (iii)  all other or additional stock, notes, limited liability
     company interests, partnership interests, instruments or other
     securities or property (including, but not limited to, cash) which
     may be paid in respect of the Collateral by reason of any
     consolidation, merger, exchange of stock, conveyance of assets,
     liquidation or similar corporate reorganization.

Nothing contained in this Section 6 shall limit or restrict in any way
the Pledgee's right to receive the proceeds of the Collateral in any
form in accordance with Section 3 of this Agreement.  All dividends,
distributions or other payments which are received by the respective
Pledgor contrary to the provisions of this Section 6 or Section 7 shall
be received in trust for the benefit of the Pledgee, shall be segregated
from other property or funds of such Pledgor and shall be forthwith paid
over to the Pledgee as Collateral in the same form as so received (with
any necessary endorsement).

          7.  REMEDIES IN CASE OF AN EVENT OF DEFAULT OR A SPECIFIED
DEFAULT.  In the event an Event of Default or a Specified Default shall
have occurred and be continuing, the Pledgee shall be entitled to
exercise all of the rights, powers and remedies (whether vested in it by
this Agreement or by any other Secured Debt Agreement or by law) for the
protection and enforcement of its rights in respect of the Collateral,
including, without limitation, all the rights and remedies of a secured
party upon default under the Uniform Commercial Code of the State of New
York, and the Pledgee shall be entitled, without limitation, to exercise
any or all of the following rights, which each Pledgor hereby agrees to
be commercially reasonable:



        (i)  to receive all amounts payable in respect of the
     Collateral otherwise payable under Section 6 to such Pledgor;

       (ii)  to transfer all or any part of the Collateral into the
     Pledgee's name or the name of its nominee or nominees; provided,
     however, that the failure to give such notice shall not affect the
     validity of such transfer;

      (iii)  to accelerate any Pledged Note which may be accelerated in
     accordance with its terms, and take any other lawful action to
     collect upon any Pledged Note (including, without limitation, to
     make any demand for payment thereon);

       (iv)  to vote all or any part of the Collateral (whether or not
     transferred into the name of the Pledgee) and give all consents,
     waivers and ratifications in respect of the Collateral and
     otherwise act with respect thereto as though it were the outright
     owner thereof (each Pledgor hereby irrevocably constituting and
     appointing the Pledgee the proxy and attorney-in-fact of such
     Pledgor, with full power of substitution to do so);

        (v)  at any time or from time to time to sell, assign and
     deliver, or grant options to purchase, all or any part of the
     Collateral, or any interest therein, at any public or private sale,
     without demand of performance, advertisement or notice of intention
     to sell or of the time or place of sale or adjournment thereof or
     to redeem or otherwise (all of which are hereby waived by each
     Pledgor), for cash, on credit or for other property, for immediate
     or future delivery without any assumption of credit risk, and for
     such price or prices and on such terms as the Pledgee in its
     absolute discretion may determine; provided that at least 10 days'
     notice of the time and place of any such sale shall be given to
     such Pledgor.  The Pledgee shall not be obligated to make such sale
     of Collateral regardless of whether any such notice of sale has
     theretofore been given.  Each purchaser at any such sale shall hold
     the property so sold absolutely free from any claim or right on the
     part of each Pledgor, and each Pledgor hereby waives and releases
     to the fullest extent permitted by law any right or equity of
     redemption with respect to the Collateral, whether before or after
     sale hereunder, all rights, if any, of marshalling the Collateral
     and any other security for the Obligations or otherwise, and all
     rights, if any, of stay and/or appraisal which it now has or may at
     any time in the future have under rule of law or statute now
     existing or hereafter enacted.  At any such sale, unless prohibited
     by applicable law, the Pledgee on behalf of all Secured Creditors
     (or certain of them) may bid for and purchase (by bidding in
     Obligations or otherwise) all or any part of the Collateral so sold
     free from any such right or equity of redemption.  Neither the
     Pledgee nor any other Secured Creditor shall be liable for failure
     to collect or realize upon any or all of the Collateral or for any
     delay in so doing nor shall any of them be under any obligation to
     take any action whatsoever with regard thereto; and

       (vi)  to set-off any and all Collateral against any and all
     Obligations, and to withdraw any and all cash or other Collateral
     from any and all Collateral Accounts and to apply such cash and
     other Collateral to the payment of any and all Obligations.



          8.  REMEDIES, ETC., CUMULATIVE.  Each right, power and remedy
of the Pledgee provided for in this Agreement or any other Secured Debt
Agreement, or now or hereafter existing at law or in equity or by
statute shall be cumulative and concurrent and shall be in addition to
every other such right, power or remedy.  The exercise or beginning of
the exercise by the Pledgee or any other Secured Creditor of any one or
more of the rights, powers or remedies provided for in this Agreement or
any other Secured Debt Agreement or now or hereafter existing at law or
in equity or by statute or otherwise shall not preclude the simultaneous
or later exercise by the Pledgee or any other Secured Creditor of all
such other rights, powers or remedies, and no failure or delay on the
part of the Pledgee or any other Secured Creditor to exercise any such
right, power or remedy shall operate as a waiver thereof.  Unless
otherwise required by the Credit Documents, no notice to or demand on
any Pledgor in any case shall entitle such Pledgor to any other or
further notice or demand in similar other circumstances or constitute a
waiver of any of the rights of the Pledgee or any other Secured Creditor
to any other or further action in any circumstances without demand or
notice.  The Secured Creditors agree that this Agreement may be enforced
only by the action of the Pledgee, acting upon the instructions of the
Required Banks (or, after the date on which all Credit Document
Obligations have been paid in full, the holders of at least a majority
of the outstanding Other Obligations) and that no other Secured Creditor
shall have any right individually to seek to enforce or to enforce this
Agreement or to realize upon the security to be granted hereby, it being
understood and agreed that such rights and remedies may be exercised by
the Pledgee or the holders of at least a majority of the outstanding
Other Obligations, as the case may be, for the benefit of the Secured
Creditors upon the terms of this Agreement and the other Credit
Documents.

          9.  APPLICATION OF PROCEEDS.  (a)  All moneys collected by the
Pledgee upon any sale or other disposition of the Collateral pursuant to
the terms of this Agreement, together with all other moneys received by
the Pledgee hereunder, shall be applied to the payment of the
Obligations in the manner provided in Section 7.4 of the Security
Agreement.  (b)  It is understood and agreed that the Pledgors shall
remain jointly and severally liable to the extent of any deficiency
between the amount of proceeds of the Collateral hereunder and the
aggregate amount of the Obligations.

          10.  PURCHASERS OF COLLATERAL.  Upon any sale of the
Collateral by the Pledgee hereunder (whether by virtue of the power of
sale herein granted, pursuant to judicial process or otherwise), the
receipt of the Pledgee or the officer making such sale of the purchase
money paid as consideration pursuant to such sale shall be a sufficient
discharge to the purchaser or purchasers of the Collateral so sold, and
such purchaser or purchasers shall not be obligated to see to the
application of any part of the purchase money paid over to the Pledgee
or such officer or be answerable in any way for the misapplication or
nonapplication thereof.



          11.  INDEMNITY.  Each Pledgor jointly and severally agrees (i)
to indemnify and hold harmless the Pledgee, each other Secured Creditor
and their respective successors, assigns, employees, agents and servants
(individually an "Indemnitee", and collectively, the "Indemnitees") from
and against any and all claims, demands, losses, judgments and
liabilities (including liabilities for penalties) of whatsoever kind or
nature, and (ii) to reimburse each Indemnitee for all reasonable costs
and expenses, including reasonable attorneys' fees, in each case arising
out of or resulting from this Agreement or the exercise by any
Indemnitee of any right or remedy granted to it hereunder or under any
other Secured Debt Agreement (but excluding any claims, demands, losses,
judgments and liabilities (including liabilities for penalties) or
expenses of whatsoever kind or nature to the extent incurred or arising
by reason of gross negligence or willful misconduct of such Indemnitee).
In no event shall any Indemnitee hereunder be liable, in the absence of
gross negligence or willful misconduct on its part, for any matter or
thing in connection with this Agreement other than to account for monies
or other property actually received by it in accordance with the terms
hereof.  If and to the extent that the obligations of any Pledgor under
this Section 11 are unenforceable for any reason, each Pledgor hereby
agrees to make the maximum contribution to the payment and satisfaction
of such obligations which is permissible under applicable law. The
indemnity obligations of each Pledgor contained in this Section 11 shall
continue in full force and effect notwithstanding the full payment of
all the Notes issued under the Credit Agreement, the termination of all
Interest Rate Protection and Other Hedging Agreements and Letters of
Credit, and the payment of all other Obligations and notwithstanding the
discharge thereof.

          12.  FURTHER ASSURANCES; POWER OF ATTORNEY.  (a)  Each Pledgor
agrees that it will join with the Pledgee in executing and, at such
Pledgor's own expense, file and refile under the Uniform Commercial Code
such financing statements, continuation statements and other documents
in such offices as the Pledgee (acting on its own or on the instructions
of the Required Banks) may reasonably deem necessary or appropriate and
wherever required or permitted by law in order to perfect and preserve
the Pledgee's security interest in the Collateral hereunder and hereby
authorizes the Pledgee to file financing statements and amendments
thereto relative to all or any part of the Collateral without the
signature of such Pledgor where permitted by law, and agrees to do such
further acts and things and to execute and deliver to the Pledgee such
additional conveyances, assignments, agreements and instruments as the
Pledgee may reasonably require or deem advisable to carry into effect
the purposes of this Agreement or to further assure and confirm unto the
Pledgee its rights, powers and remedies hereunder or thereunder.

          (b)  Each Pledgor hereby appoints the Pledgee such Pledgor's
attorney-in-fact, with full authority in the place and stead of such
Pledgor and in the name of such Pledgor or otherwise, from time to time
after the occurrence and during the continuance of an Event of Default,
in the Pledgee's discretion to take any action and to execute any
instrument which the Pledgee may deem necessary or advisable to
accomplish the purposes of this Agreement.



          13.  THE PLEDGEE AS COLLATERAL AGENT.  The Pledgee will hold
in accordance with this Agreement all items of the Collateral at any
time received under this Agreement.  It is expressly understood and
agreed that the obligations of the Pledgee as holder of the Collateral
and interests therein and with respect to the disposition thereof, and
otherwise under this Agreement, are only those expressly set forth in
this Agreement.  The Pledgee shall act hereunder on the terms and
conditions set forth herein and in Section 11 of the Credit Agreement.

          14.  TRANSFER BY THE PLEDGORS.  Except for sales or
dispositions of Collateral permitted pursuant to the Credit Agreement,
no Pledgor will sell or otherwise dispose of, grant any option with
respect to, or mortgage, pledge or otherwise encumber any of the
Collateral or any interest therein (except in accordance with the terms
of this Agreement and the other Secured Debt Agreements).

          15.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE
PLEDGORS.  (a)  Each Pledgor represents, warrants and covenants that:

        (i)  it is the legal, beneficial and record owner of, and has
     good and marketable title to, all Collateral consisting of one or
     more Securities and that it has sufficient interest in all
     Collateral in which a security interest is purported to be created
     hereunder for such security interest to attach (subject, in each
     case, to no pledge, lien, mortgage, hypothecation, security
     interest, charge, option, Adverse Claim or other encumbrance
     whatsoever, except the liens and security interests created by this
     Agreement or permitted under the Credit Agreement);

        (ii)  it has full power, authority and legal right to pledge all
     the Collateral pledged by it pursuant to this Agreement;

        (iii)  this Agreement has been duly authorized, executed and
     delivered by such Pledgor and constitutes a legal, valid and
     binding obligation of such Pledgor enforceable against such Pledgor
     in accordance with its terms, except to the extent that the
     enforceability thereof may be limited by applicable bankruptcy,
     insolvency, reorganization, moratorium or other similar laws
     generally affecting creditors' rights and by equitable principles
     (regardless of whether enforcement is sought in equity or at law);

       (iv)  except to the extent already obtained or made, no consent
     of any other party (including, without limitation, any stockholder,
     member, partner or creditor of such Pledgor or any of its
     Subsidiaries) and no consent, license, permit, approval or
     authorization of, exemption by, notice or report to, or
     registration, filing or declaration with, any governmental
     authority is required to be obtained by such Pledgor in connection
     with (a) the execution, delivery or performance of this Agreement,
     (b) the validity or enforceability of this Agreement (except as set
     forth in clause (iii) above), (c) the perfection or enforceability
     of the Pledgee's security interest in the Collateral or (d) except
     for compliance with or as may be required by applicable securities
     laws, the exercise by such Pledgee of any of its rights or remedies
     provided herein;

        (v)  the execution, delivery and performance of this Agreement
     will not violate any provision of any applicable law or regulation
     or of any order, judgment, writ, award or decree of any court,
     arbitrator or governmental authority, domestic or foreign,
     applicable to such Pledgor, or of the certificate of incorporation,
     operating agreement, limited liability company agreement or by-laws
     of such Pledgor or of any securities issued by such Pledgor or any
     of its Subsidiaries, or of any mortgage, deed of trust, indenture,
     lease, loan agreement, credit agreement or other contract,
     agreement or instrument or undertaking to which such Pledgor or any
     of its Subsidiaries is a party or which purports to be binding upon
     such Pledgor or any of its Subsidiaries or upon any of their
     respective assets and will not result in the creation or imposition
     of (or the obligation to create or impose) any lien or encumbrance
     on any of the assets of such Pledgor or any of its Subsidiaries
     except as contemplated by this Agreement (other than the Liens
     created by the Collateral Documents);

       (vi)  all of the Collateral (consisting of Securities other than
     Limited Liability Company Interests and Partnership Interests) has
     been duly and validly issued, is fully paid and non-assessable and
     is subject to no options to purchase or similar rights;

       (vii)  each of the Pledged Notes constitutes, or when executed by
     the obligor thereof will constitute, the legal, valid and binding
     obligation of such obligor, enforceable in accordance with its
     terms, except to the extent that the enforceability thereof may be
     limited by applicable bankruptcy, insolvency, reorganization,
     moratorium or other similar laws generally affecting creditors'
     rights and by equitable principles (regardless of whether
     enforcement is sought in equity or at law);

       (viii)  the pledge, collateral assignment and delivery to the
     Pledgee of the Collateral consisting of certificated securities
     pursuant to this Agreement creates a valid and perfected first
     priority security interest in such Securities, and the proceeds
     thereof, subject to no prior Lien or encumbrance or to any
     agreement purporting to grant to any third party a Lien or
     encumbrance on the property or assets of such Pledgor which would
     include the Securities (other than Permitted Liens) and the Pledgee
     is entitled to all the rights, priorities and benefits afforded by
     the UCC or other relevant law as enacted in any relevant
     jurisdiction to perfect security interests in respect of such
     Collateral; and

       (ix)  "control" (as defined in Section 8-106 of the UCC) has
     been obtained by the Pledgee over all Collateral consisting of
     Securities (including Notes which are Securities) with respect to
     which such "control" may be obtained pursuant to Section 8-106 of
     the UCC.

          (b)  Each Pledgor covenants and agrees that it will defend the
Pledgee's right, title and security interest in and to the Securities
and the proceeds thereof against the claims and demands of all persons
whomsoever; and each Pledgor covenants and agrees that it will have like
title to and right to pledge any other property at any time hereafter
pledged to the Pledgee as Collateral hereunder and will likewise defend
the right thereto and security interest therein of the Pledgee and the
other Secured Creditors.

          (c)   Each Pledgor covenants and agrees that it will take no
action which would violate any of the terms of any Secured Debt
Agreement.

          16.  CHIEF EXECUTIVE OFFICE; RECORDS.  The chief executive
office of each Pledgor is located at the address specified in Annex F
hereto.  Each Pledgor will not move its chief executive office except to
such new location as such Pledgor may establish in accordance with the
last sentence of this Section 16.  The originals of all documents in the
possession of such Pledgor evidencing all Collateral, including but not
limited to all Limited Liability Company Interests and Partnership
Interests, and the only original books of account and records of such
Pledgor relating thereto are, and will continue to be, kept at such
chief executive office at the location specified in Annex F hereto, or
at such new locations as such Pledgor may establish in accordance with
the last sentence of this Section 16.  All Limited Liability Company
Interests and Partnership Interests are, and will continue to be,
maintained at, and controlled and directed (including, without
limitation, for general accounting purposes) from, such chief executive
office location specified in Annex F hereto, or such new locations as
the respective Pledgor may establish in accordance with the last
sentence of this Section 16.  No Pledgor shall establish a new location
for such offices until (i) it shall have given to the Collateral Agent
not less than 30 days' prior written notice of its intention so to do,
clearly describing such new location and providing such other
information in connection therewith as the Collateral Agent may
reasonably request and (ii) with respect to such new location, it shall
have taken all action, satisfactory to the Collateral Agent, to maintain
the security interest of the Collateral Agent in the Collateral intended
to be granted hereby at all times fully perfected and in full force and
effect.  Promptly after establishing a new location for such offices in
accordance with the immediately preceding sentence, the respective
Pledgor shall deliver to the Pledgee a supplement to Annex F hereto so
as to cause such Annex F hereto to be complete and accurate.

          17.  PLEDGORS' OBLIGATIONS ABSOLUTE, ETC.  The obligations of
each Pledgor under this Agreement shall be absolute and unconditional
and shall remain in full force and effect without regard to, and shall
not be released, suspended, discharged, terminated or otherwise affected
by, any circumstance or occurrence whatsoever (other than termination of
this Agreement pursuant to Section 19 hereof), including, without
limitation:

        (i)  any renewal, extension, amendment or modification of, or
     addition or supplement to or deletion from any Secured Debt
     Agreement (other than this Agreement in accordance with its terms),
     or any other instrument or agreement referred to therein, or any
     assignment or transfer of any thereof;

       (ii)  any waiver, consent, extension, indulgence or other action
     or inaction under or in respect of any such agreement or instrument
     or this Agreement (other than a waiver, consent or extension with
     respect to this Agreement in accordance with its terms);

      (iii)  any furnishing of any additional security to the Pledgee
     or its assignee or any acceptance thereof or any release of any
     security by the Pledgee or its assignee;

       (iv)  any limitation on any party's liability or obligations
     under any such instrument or agreement or any invalidity or
     unenforceability, in whole or in part, of any such instrument or
     agreement or any term thereof; or

        (v)  any bankruptcy, insolvency, reorganization, composition,
     adjustment, dissolution, liquidation or other like proceeding
     relating to any Pledgor or any Subsidiary of any Pledgor, or any
     action taken with respect to this Agreement by any trustee or
     receiver, or by any court, in any such proceeding, whether or not
     such Pledgor shall have notice or knowledge of any of the
     foregoing.

          18.  SALE OF COLLATERAL WITHOUT REGISTRATION. (a)  If an Event
of Default shall have occurred and be continuing and any Pledgor shall
have received from the Pledgee a written request or requests that such
Pledgor cause any registration, qualification or compliance under any
federal or state securities law or laws to be effected with respect to
all or any part of the Collateral consisting of Securities, Limited
Liability Company Interests or Partnership Interests, such Pledgor as
soon as practicable and at its expense will use its best efforts to
cause such registration to be effected (and be kept effective) and will
use its best efforts to cause such qualification and compliance to be
effected (and be kept effective) as may be so requested and as would
permit or facilitate the sale and distribution of such Collateral
consisting of Securities, Limited Liability Company Interests or
Partnership Interests, including, without limitation, registration under
the Securities Act of 1933, as then in effect (or any similar statute
then in effect), appropriate qualifications under applicable blue sky or
other state securities laws and appropriate compliance with any other
governmental requirements; provided, that the Pledgee shall furnish to
such Pledgor such information regarding the Pledgee as such Pledgor may
request in writing and as shall be required in connection with any such
registration, qualification or compliance.  Each Pledgor will cause the
Pledgee to be kept reasonably advised in writing as to the progress of
each such registration, qualification or compliance and as to the
completion thereof, will furnish to the Pledgee such number of
prospectuses, offering circulars and other documents incident thereto as
the Pledgee from time to time may reasonably request, and will
indemnify, to the extent permitted by law, the Pledgee and all other
Secured Creditors participating in the distribution of such Collateral
consisting of Securities, Limited Liability Company Interests or
Partnership Interests against all claims, losses, damages and
liabilities caused by any untrue statement (or alleged untrue statement)
of a material fact contained therein (or in any related registration
statement, notification or the like) or by any omission (or alleged
omission) to state therein (or in any related registration statement,
notification or the like) a material fact required to be stated therein
or necessary to make the statements therein not misleading, except
insofar as the same may have been caused by an untrue statement or
omission based upon information furnished in writing to such Pledgor by
the Pledgee expressly for use therein.



(b)  If at any time when the Pledgee shall determine to exercise its
right to sell all or any part of the Collateral consisting of
Securities, Limited Liability Company Interests or Partnership
Interests pursuant to Section 7, and such Collateral or the part thereof
to be sold shall not, for any reason whatsoever, be effectively
registered under the Securities Act of 1933, as then in effect, the
Pledgee may, in its sole and absolute discretion, sell such Collateral
or part thereof by private sale in such manner and under such
circumstances as the Pledgee may deem necessary or advisable in order
that such sale may legally be effected without such registration.
Without limiting the generality of the foregoing, in any such event the
Pledgee, in its sole and absolute discretion: (i) may proceed to make
such private sale notwithstanding that a registration statement for the
purpose of registering such Collateral or part thereof shall have been
filed under such Securities Act; (ii) may approach and negotiate with a
single possible purchaser to effect such sale; and (iii) may restrict
such sale to a purchaser who will represent and agree that such
purchaser is purchasing for its own account, for investment, and not
with a view to the distribution or sale of such Collateral or part
thereof.  In the event of any such sale, the Pledgee shall incur no
responsibility or liability for selling all or any part of the
Collateral at a price which the Pledgee, in its sole and absolute
discretion, may in good faith deem reasonable under the circumstances,
notwithstanding the possibility that a substantially higher price might
be realized if the sale were deferred until the registration as
aforesaid.

          19.  TERMINATION; RELEASE.  (a)  On the Termination Date (as
defined below), this Agreement shall terminate (provided that all
indemnities set forth herein including, without limitation, in Section
11 hereof shall survive any such termination) and the Pledgee, at the
request and expense of the respective Pledgor, will execute and deliver
to such Pledgor a proper instrument or instruments acknowledging the
satisfaction and termination of this Agreement (including, without
limitation, UCC termination statements and instruments of satisfaction,
discharge and/or reconveyance), and will duly release from the security
interest created hereby and assign, transfer and deliver to such Pledgor
(without recourse and without any representation or warranty) such of
the Collateral as may be in the possession of the Pledgee and as has not
theretofore been sold or otherwise applied or released pursuant to this
Agreement, together with any moneys at the time held by the Pledgee or
any of its sub-agents hereunder and, with respect to any Collateral
consisting of an Uncertificated Security (other than an Uncertificated
Security credited on the books of a Clearing Corporation), a Partnership
Interest or a Limited Liability Company Interest, a termination of the
agreement relating thereto executed and delivered by the issuer of such
Uncertificated Security pursuant to Section 3.2(a)(ii) or by the

respective partnership or limited liability company pursuant to Section
3.2(a)(iv).  As used in this Agreement, "Termination Date" shall mean
the date upon which the Total Commitment and all Interest Rate
Protection Agreements and Other Hedging Agreements have been terminated,
no Note (as defined in the Credit Agreement) or Letter of Credit is
outstanding (other than Letters of Credit, together with all Fees that
have accrued and will accrue thereon through the stated termination date
of such Letters of Credit, which have been supported in a manner
satisfactory to the Letter of Credit Issuer in its sole and absolute
discretion) and all other Obligations (other than indemnities described
in Section 11 hereof and in Section 12.13 of the Credit Agreement which
are not then due and payable) have been paid in full.

          (b)  In the event that any part of the Collateral is sold or
otherwise disposed of (to a Person other than a Credit Party) (x) at any
time prior to the time at which all Credit Document Obligations have
been paid in full, all Commitments and Letters of Credit under the
Credit Agreement have been terminated (other than Letters of Credit,
together with all Fees that have accrued and will accrue thereon through
the stated termination date of such Letters of Credit, which have been
supported in a manner satisfactory to the Letter of Credit Issuer in its
sole and absolute discretion) in connection with a sale or disposition
permitted by Section 8.02 of the Credit Agreement or is otherwise
released at the direction of the Required Banks (or all the Banks if
required by Section 12.12 of the Credit Agreement) or (y) at any time
thereafter, to the extent permitted by the other Secured Debt
Agreements, and in the case of clauses (x) and (y), the proceeds of such
sale or disposition (or from such release) are applied in accordance
with the terms of the Credit Agreement or such other Secured Debt
Agreement, as the case may be, to the extent required to be so applied,
the Pledgee, at the request and expense of such Pledgor, will duly
release from the security interest created hereby and assign, transfer
and deliver to such Pledgor (without recourse and without any
representation or warranty) such of the Collateral as is then being (or
has been) so sold or released and as may be in possession of the Pledgee
and has not theretofore been released pursuant to this Agreement.

          (c)  At any time that any Pledgor desires that Collateral be
released as provided in the foregoing Section 19(a) or (b), it shall
deliver to the Pledgee a certificate signed by a principal executive
officer of such Pledgor stating that the release of the respective
Collateral is permitted pursuant to Section 19(a) or (b).  If reasonably
requested by the Pledgee (although the Pledgee shall have no obligation
to make any such request), the relevant Pledgor shall furnish
appropriate legal opinions (from counsel reasonably acceptable to the
Pledgee) to the effect set forth in the immediately preceding sentence.
The Pledgee shall have no liability whatsoever to any Secured Creditor
as the result of any release of Collateral by it as permitted by this
Section 19.

          20.  NOTICES, ETC.  All notices and other communications
hereunder shall be in writing and shall be delivered or mailed by first

     address as such Bank shall have specified in the Credit Agreement;

          (iv) if to any Other Creditor, at such address as such Other
     Creditor shall have specified in writing to the U.S. Borrower and
     the Pledgee;

or at such address as shall have been furnished in writing by any Person
described above to the party required to give notice hereunder.

         21.  PLEDGEE NOT A PARTNER OR LIMITED LIABILITY COMPANY
MEMBER.   (a)   Nothing herein shall be construed to make the Pledgee or
any other Secured Creditor liable as a member of any limited liability
company or partnership and neither the Pledgee nor any other Secured
Creditor by virtue of this Agreement or otherwise (except as referred to
in the following sentence) shall have any of the duties, obligations or
liabilities of a member of any limited liability company or partnership.
The parties hereto expressly agree that, unless the Pledgee shall become
the absolute owner of Collateral consisting of a Limited Liability
Company Interest or Partnership Interest pursuant hereto, this Agreement
shall not be construed as creating a partnership or joint venture among
the Pledgee, any other Secured Creditor and/or any Pledgor.

          (b)  Except as provided in the last sentence of paragraph (a)
of this Section 21, the Pledgee, by accepting this Agreement, did not
intend to become a member of any limited liability company or
partnership or otherwise be deemed to be a co-venturer with respect to
any Pledgor or any limited liability company or partnership either
before or after an Event of Default shall have occurred.  The Pledgee
shall have only those powers set forth herein and the Secured Creditors
shall assume none of the duties, obligations or liabilities of a member
of any limited liability company or partnership or any Pledgor except as
provided in the last sentence of paragraph (a) of this Section 21.

          (c)  The Pledgee and the other Secured Creditors shall not be
obligated to perform or discharge any obligation of any Pledgor as a
result of the pledge hereby effected.

          (d)  The acceptance by the Pledgee of this Agreement, with all
the rights, powers, privileges and authority so created, shall not at
any time or in any event obligate the Pledgee or any other Secured
Creditor to appear in or defend any action or proceeding relating to the
Collateral to which it is not a party, or to take any action hereunder
or thereunder, or to expend any money or incur any expenses or perform
or discharge any obligation, duty or liability under the Collateral.



          22.  WAIVER; AMENDMENT.  Except as contemplated in Section 25
hereof, none of the terms and conditions of this Agreement may be
changed, waived, discharged or terminated in any manner whatsoever
unless such change, waiver, discharge or termination is in writing duly
signed by each Pledgor directly and adversely affected thereby and the
Pledgee (with the consent of (x) the Required Banks (or, to the extent
required by Section 12.12 of the Credit Agreement, all of the Banks) at
all times prior to the time at which all Credit Document Obligations
(other than those arising from indemnities for which no request has been
made) have been paid in full and all Commitments under the Credit
Agreement have been terminated or (y) the holders of at least a majority
of the outstanding Other Obligations at all times after the time at
which all Credit Document Obligations (other than those arising from
indemnities for which no request has been made) have been paid in full
and all Commitments have been terminated, provided, that any change,
waiver, modification or variance affecting the rights and benefits of a
single Class (as defined below) of Secured Creditors (and not all
Secured Creditors in a like or similar manner) shall require the written
consent of the Requisite Creditors (as defined below) of such Class of
Secured Creditors.  For the purpose of this Agreement, the term "Class"
shall mean each class of Secured Creditors, i.e., whether (x) the Bank
Creditors as holders of the Credit Document Obligations or (y) the Other
Creditors as holders of the Other Obligations.  For the purpose of this
Agreement, the term "Requisite Creditors" of any Class shall mean each
of (x) with respect to the Credit Document Obligations, the Required
Banks and (y) with respect to the Other Obligations, the holders of at
least a majority of all obligations outstanding from time to time under
the Interest Rate Protection Agreements and Other Hedging Agreements.

          23.  MISCELLANEOUS.  This Agreement shall create a continuing
security interest in the Collateral and shall (i) remain in full force
and effect, subject to release and/or termination as set forth in
Section 19, (ii) be binding upon each Pledgor, its successors and
assigns; provided, however, that no Pledgor shall assign any of its
rights or obligations hereunder without the prior written consent of the
Pledgee (with the prior written consent of the Required Banks or to the
extent required by Section 12.12 of the Credit Agreement, all of the
Banks), and (iii) inure, together with the rights and remedies of the
Pledgee hereunder, to the benefit of the Pledgee, the other Secured
Parties and their respective successors, transferees and assigns. THIS
AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL
BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH,
THE INTERNAL LAWS OF THE STATE OF NEW YORK.  The headings of the several
sections and subsections in this Agreement are for purposes of reference
only and shall not limit or define the meaning hereof.  This Agreement
may be executed in any number of counterparts, each of which shall be an
original, but all of which together shall constitute one instrument.  In
the event that any provision of this Agreement shall prove to be invalid
or unenforceable, such provision shall be deemed to be severable from
the other provisions of this Agreement which shall remain binding on all
parties hereto.

          24.   WAIVER OF JURY TRIAL.  Each Pledgor hereby irrevocably
waives all right to a trial by jury in any action, proceeding or
counterclaim arising out of or relating to this Agreement or the
transactions contemplated hereby.



          25.  ADDITIONAL PLEDGORS.  It is understood and agreed that
any Subsidiary of Holdings that is required to execute a counterpart of
this Agreement after the date hereof pursuant to Section 7.16 and/or
8.14 of the Credit Agreement shall automatically become a Pledgor
hereunder by executing a counterpart hereof and delivering the same to
the Pledgee.

          26.  RECOURSE.  This Agreement is made with full recourse to
the Pledgors and pursuant to and upon all the representations,
warranties, covenants and agreements on the part of the Pledgors
contained herein and in the other Secured Debt Agreements and otherwise
in writing in connection herewith or therewith.

         27.  LIMITED OBLIGATIONS.  It is the desire and intent of each
Pledgor and the Secured Creditors that this Agreement shall be enforced
against each Pledgor to the fullest extent permissible under the laws
and public policies applied in each jurisdiction in which enforcement is

sought.  Notwithstanding anything to the contrary contained herein, in
furtherance of the foregoing, it is noted that the obligations of each
Pledgor constituting a U.S. Subsidiary Guarantor have been limited as
provided in the Subsidiary Guaranty.

             [Remainder of page intentionally left blank]



          IN WITNESS WHEREOF, each Pledgor and the Pledgee have caused
this Agreement to be executed by their duly elected officers duly
authorized as of the date first above written.
