satisfactory to the Collateral Trustee, together, in respect of any Additional

hereunder as additional collateral security for the Secured Obligations. If any
sum of money or property so paid or distributed in respect of any Pledged
Collateral shall be received by such Grantor, such Grantor shall, until such
money or property is paid or delivered to the Collateral Trustee, hold such
money or property in trust for the Collateral Trustee, segregated from other
funds of such Grantor, as additional security for the Secured Obligations.

          (c) Except as provided in Article V (), such Grantor shall be entitled
to exercise all voting, consent and corporate rights with respect to the Pledged

          (d) In the case of each Grantor that is an issuer of Pledged
Collateral, such Grantor agrees to be bound by the terms of this Agreement
relating to the Pledged Collateral issued by it and shall comply with such terms
insofar as such terms are applicable to it. In the case of each Grantor that is
a partner in a Partnership, such Grantor hereby consents to the extent required
by the applicable Partnership Agreement to the pledge by each other Grantor,
pursuant to the terms hereof, of the Pledged Partnership Interests in such
Partnership and to the transfer of such Pledged Partnership Interests to the
Collateral Trustee or its nominee and, during the continuance of an Actionable
Default, to the substitution of the Collateral Trustee or its nominee as a
substituted partner in such Partnership with all the rights, powers and duties
of a general partner or a limited partner, as the case may be. In the case of
each Grantor member of an LLC, such Grantor hereby consents to the extent
required by the applicable LLC Agreement to the pledge by each other Grantor,

of the Collateral Trustee or its nominee as a substituted member of the LLC with
all the rights, powers and duties of a member of the LLC in question.

or Partnership Agreement that in any way adversely affects the perfection of the
security interest of the Collateral Trustee in the Pledged Partnership Interests
or Pledged LLC Interests pledged by such Grantor hereunder, including any
amendment electing to treat the membership interest or partnership interest of
such Grantor as a security under Section 8-103 of the UCC.

          Section 4.5 Payment of Obligations

          Such Grantor shall pay and discharge or otherwise satisfy at or before
maturity or before they become delinquent, as the case may be, all taxes,
assessments and governmental charges or levies imposed upon the Shared
Collateral or in respect of income or profits therefrom, as well as all claims
of any kind (including claims for labor, materials and supplies) against or with
respect to the Shared Collateral, except that no such charge need be paid if the
amount or validity thereof is currently being contested in good faith by
appropriate proceedings, reserves in conformity with GAAP with respect thereto
have been provided on the books of such Grantor and such proceedings could not
reasonably be expected to result in the sale, forfeiture or loss of any material
portion of the Shared Collateral or any interest therein.

          Section 4.6 Delivery of Instruments.

          If any amount payable under or in connection with any of the Shared
Collateral owned by such Grantor shall be or become evidenced by an Instrument,
such Grantor shall immediately deliver such Instrument to the Collateral
Trustee, duly indorsed in a manner satisfactory to the Collateral Trustee, or,
if consented to by the Collateral Trustee, shall mark all such Instruments and

secured hereby are subject to the security interest of Citibank N.A., as
Collateral Trustee".

          Section 4.7 Insurance

          Such Grantor shall (i) maintain, and cause to be maintained for each
of its Subsidiaries all insurance required by the Credit Agreement, the Shared
Collateral Documents or any other Secured Debt Document and (ii) cause all such
insurance to name the Collateral Trustee on behalf of the Secured Parties as
additional insured or loss payee, as appropriate, and to provide

shall be effective until after 30 days' written notice thereof to the Collateral
Trustee. All insurance proceeds with respect to the Shared Collateral shall be
applied as set forth in the Credit Agreement; provided, that if required by the
Bank Administrative Agent or the Required Holders of Secured Debt, as
applicable, after receipt of a Notice of Actionable Default, all insurance
proceeds shall be held by the Collateral Trustee and deposited into the
Collateral Account.

     Article V. Remedial Provisions

          Section 5.1 Code and Other Remedies

          During the continuance of an Actionable Default, the Collateral
Trustee may (subject to the terms of the Collateral Trust Agreement) exercise,
in addition to all other rights and remedies granted to it in this Agreement and
in any other instrument or agreement securing, evidencing or relating to the
Secured Obligations, all rights and remedies of a secured party under the UCC or
any other applicable law. Without limiting the generality of the foregoing, the
Collateral Trustee, without demand of performance or other demand, presentment,
protest, advertisement or notice of any kind (except any notice required by law
referred to below) to or upon any Grantor or any other Person (all and each of
which demands, defenses, advertisements and notices are hereby waived), may
(subject to the terms of the Collateral Trust Agreement) in such circumstances
forthwith collect, receive, appropriate and realize upon any Shared Collateral,
and may forthwith sell, lease, assign, give option or options to purchase, or
otherwise dispose of and deliver any Shared Collateral (or contract to do any of
the foregoing), in one or more parcels at public or private sale or sales, at
any exchange, broker's board or office of the Collateral Trustee or any Lender
or elsewhere upon such terms and conditions as it may deem advisable and at such
prices as it may deem best, for cash or on credit or for future delivery without
assumption of any credit risk. The Collateral Trustee shall have the right upon
any such public sale or sales, and, to the extent permitted by law, upon any
such private sale or sales, to purchase the whole or any part of the Shared
Collateral so sold, free of any right or equity of redemption in any Grantor,
which right or equity is hereby waived and released. Each Grantor further
agrees, at the Collateral Trustee's request, during the continuance of an
Actionable Default, to assemble the Shared Collateral and make it available to
the Collateral Trustee at places that the Collateral Trustee shall reasonably
select, whether at such Grantor's premises or elsewhere. The Collateral Trustee
shall apply the net proceeds of any action taken by it pursuant to this Section
5.1, after deducting all reasonable costs and expenses of every kind incurred in
connection therewith or incidental to the care or safekeeping of any Shared
Collateral or in any way relating to the Shared Collateral or the rights of the
Collateral Trustee and any other Secured Party hereunder, including reasonable
attorneys' fees and disbursements, to the payment in whole or in part of the
Secured Obligations, in such order as the Collateral Trust Agreement shall
prescribe, and only after such application and after the payment by the
Collateral Trustee of any other amount required by any provision of law, need
the Collateral Trustee account for the surplus, if any, to any Grantor. To the
extent permitted by applicable law, each Grantor waives all claims, damages and
demands it may acquire against the Collateral Trustee or any other Secured Party
arising out of the exercise by them of any rights hereunder. If any notice of a
proposed sale or other disposition of Shared Collateral shall be required by
law, such notice shall be deemed reasonable and proper if given at least 10 days
before such sale or other disposition.

          Section 5.2 Pledged Collateral

Trustee shall have the right to receive any Proceeds of the Pledged Collateral
and make application thereof to the Obligations in the order set forth in the
Collateral Trust Agreement and (ii) the Collateral Trustee or its nominee may
(subject to the terms of the Collateral Trust Agreement) exercise (A) any
voting, consent, corporate and other right pertaining to the Pledged Collateral
at any meeting of shareholders, partners or members, as the case may be, of the
relevant issuer or issuers of Pledged Collateral or otherwise and (B) any right
of conversion, exchange and subscription and any other right, privilege or
option pertaining to the Pledged Collateral as if it were the absolute owner
thereof (including the right to exchange at its discretion any of the Pledged
Collateral upon the merger, consolidation, reorganization, recapitalization or
other fundamental change in the corporate structure of any issuer of Pledged
Securities, the right to deposit and deliver any Pledged Collateral with any
committee, depositary, transfer agent, registrar or other designated agency upon
such terms and conditions as the Collateral Trustee may determine), all without
liability except to account for property actually received by it; provided,
however, that the Collateral Trustee shall have no duty to any Grantor to
exercise any such right, privilege or option and shall not be responsible for
any failure to do so or delay in so doing.

          (b) In order to permit the Collateral Trustee to exercise the voting
and other consensual rights that it may be entitled to exercise pursuant hereto
and to receive all dividends and other distributions that it may be entitled to
receive hereunder, (i) each Grantor shall promptly execute and deliver (or cause
to be executed and delivered) to the Collateral Trustee all such proxies,
dividend payment orders and other instruments as the Collateral Trustee may from
time to time reasonably request and (ii) without limiting the effect of clause
(i) above, such Grantor hereby grants to the Collateral Trustee an irrevocable
proxy to vote all or any part of the Pledged Collateral and to exercise all
other rights, powers, privileges and remedies to which a holder of the Pledged
Collateral would be entitled (including giving or withholding written consents
of shareholders, partners or members, as the case may be, calling special
meetings of shareholders, partners or members, as the case may be, and voting at
such meetings), which proxy shall only become effective, automatically and
without the necessity of any action (including any transfer of any Pledged
Collateral on the record books of the issuer thereof) by any other person
(including the issuer of such Pledged Collateral or any officer or agent
thereof) during the continuance of an Actionable Default and which proxy shall
only terminate upon the payment in full of the Secured Obligations.

          (c) Each Grantor hereby expressly authorizes and instructs each issuer
of any Pledged Collateral pledged hereunder by such Grantor to (i) comply with
any instruction received by it from the Collateral Trustee in writing that (A)
states that an Actionable Default has occurred and is continuing and (B) is
otherwise in accordance with the terms of this Agreement, without any other or
further instructions from such Grantor, and each Grantor agrees that such issuer
shall be fully protected in so complying and (ii) unless otherwise expressly
permitted hereby, pay any dividend or other payment with respect to the Pledged
Collateral directly to the Collateral Trustee.

          Section 5.3 Proceeds to be Turned Over To Collateral Trustee

          During the continuance of an Actionable Default, all Proceeds received
by the Collateral Trustee hereunder shall be held by the Collateral Trustee in a
Collateral Account. All

Proceeds while held by the Collateral Trustee in a Collateral Account (or by
such Grantor in trust for the Collateral Trustee) shall continue to be held as
collateral security for the Secured Obligations and shall not constitute payment
thereof until applied as provided in the Collateral Trust Agreement.

          Section 5.4 Deficiency

          Each Grantor shall remain liable for any deficiency, if the proceeds
of any sale or other disposition of the Shared Collateral are insufficient to
pay the Secured Obligations, and the fees and disbursements of any attorney
employed by the Collateral Trustee or any other Secured Party to collect such
deficiency.

          Section 5.5 Execution of Financing Statements

          Each Grantor authorizes the Collateral Trustee to file or record
financing statements and other filing or recording documents or instruments with

form and in such offices as the Collateral Trustee reasonably determines
appropriate to perfect the security interests of the Collateral Trustee under
this Agreement. A photographic or other reproduction of this Agreement shall be

          Article VI. Miscellaneous

          Section 6.1 Amendments in Writing

amended, supplemented or otherwise modified except in accordance with Section

any Grantor hereunder shall be effected in the manner provided for in Section
8.2 of the Collateral Trust Agreement.

          Section 6.3 No Waiver by Course of Conduct; Cumulative Remedies

          Neither the Collateral Trustee nor any other Secured Party shall by
any act (except by a written instrument pursuant to Section 6.1 (Amendments in
Writing)), delay, indulgence, omission or otherwise be deemed to have waived any
right or remedy hereunder or to have acquiesced in any default or event of
default under any Secured Debt Instrument. No failure to exercise, nor any delay
in exercising, on the part of the Collateral Trustee or any other Secured Party,
any right, power or privilege hereunder shall operate as a waiver thereof. No
single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. A waiver by the Collateral Trustee or any other
Secured Party of any right or remedy hereunder on any one occasion shall not be
construed as a bar to any right or remedy that the Collateral Trustee or such
other Secured Party would otherwise have on any future occasion. The rights and
remedies herein provided are

          If, pursuant to Section 7.11 (Additional Collateral and Guaranties) of

          Each Grantor further agrees that, if any payment made by any Grantor

the Shared Collateral are required to be returned by any Secured Party to such
Grantor, its estate, trustee, receiver or any other party, including any
Grantor, under any bankruptcy law, state or federal law, common law or equitable
cause, then, to the extent of such payment or repayment, any Lien or other
Shared Collateral securing such liability shall be and remain in full force and
effect, as fully as if such payment had never been made or, if prior thereto the
Lien granted hereby or other Shared Collateral securing such liability hereunder
shall have been released or terminated by virtue of such cancellation or
surrender, such Lien or other Shared Collateral shall be reinstated in full
force and effect, and such prior cancellation or surrender shall not diminish,
release, discharge, impair or otherwise affect any Lien or other Shared
Collateral securing the obligations of any Grantor in respect of the amount of
such payment.

          Section 6.12 Concerning the Collateral Trustee.

          The rights, privileges, protections and immunities afforded the
