                                       3

         rights with respect to any Pledged Property; and

                  (g)      all proceeds of any of the foregoing.

         SECTION 2.2.      Security for Obligations; Separate Liens. This Pledge
Agreement and the security interests and Liens granted and created herein
secures the payment and performance of all Secured Obligations of the Company
now or hereafter, whether direct or indirect, absolute or contingent, and
whether for principal, reimbursement obligations, interest (including any
interest accruing at the then applicable rate provided in any applicable Secured
Debt Document after the maturity of the loans and reimbursement obligations
therein and interest accruing at the then applicable rate provided in any
applicable Secured Debt Document after the filing of any petition in bankruptcy,
or the commencement of any insolvency, reorganization or like proceeding,
relating to the Company, whether or not a claim for post-filing or post-petition
interest is allowed in such proceeding), fees, premiums, penalties,
indemnifications, expenses or otherwise, and including all amounts that
constitute part of the Secured Obligations and would be owed by the Company but
for the fact that they are unenforceable or not allowed due to a pending
Bankruptcy Case or Insolvency Proceeding. Without limiting the generality of the
foregoing, it is the intent of the parties that (i) the Liens securing the
Parity Lien Obligations are subject and subordinate to the Liens securing the
Priority Lien Obligations up to the Priority Lien Cap and (ii) this Pledge
Agreement creates two separate and distinct Liens: the first Lien securing the
payment and performance of the Priority Lien Obligations and the second Lien
securing the payment and performance of the Parity Lien Obligations.

         SECTION 2.3.      Delivery of Pledged Property. All certificates or
instruments representing or evidencing any Pledged Collateral, including all

delivery, and shall be accompanied by all necessary instruments of transfer or
assignment, duly executed in blank.

                                       4


         SECTION 2.4.      Intentionally Omitted.

         SECTION 2.5.      Continuing Security Interest; Transfer of Note. This
Pledge Agreement shall create a continuing security interest in the Pledged
Collateral and, subject to Section 4.1 of the Collateral Trust Agreement and the
other Secured Debt Documents, shall

                  (a)      remain in full force and effect until payment in full
         of all Secured Obligations and the termination or expiration of all
         commitments to extend credit under all Credit Facilities the
         Indebtedness under which constitutes Priority Lien Debt,

                  (b)      be binding upon the Company and its successors,
         transferees and assigns, and

                  (c)      inure, together with the rights and remedies of the
         Collateral Trustee hereunder, to the benefit of the Collateral Trustee
         and each other Secured Party.

Without limiting the foregoing clause (c), any Secured Party may assign or
otherwise transfer (in whole or in part) any right or obligation under the
Secured Debt Documents to any other Person or entity, and such other Person or
entity shall thereupon become vested with all the rights and benefits in respect
thereof granted to such Secured Party under any Secured Debt Document (including
this Pledge Agreement) or otherwise, subject, however, to any contrary
provisions in such assignment or transfer, and to the applicable provisions of
each of the Secured Debt Documents. Upon the payment in full and discharge of
all Secured Obligations that are then outstanding, due and payable and the
termination or expiration of all commitments to extend credit under all Credit
Facilities, the Indebtedness under which constitutes Priority Lien Debt, the
security interest granted herein shall terminate and all rights to the Pledged
Collateral shall revert to the Company. Upon any such termination or release of
the Lien provided for hereunder in accordance with the Secured Debt Documents,
the Collateral Trustee will, at the Company's sole expense, deliver to the
Company, without any representations, warranties or recourse of any kind
whatsoever, all certificates and instruments representing or evidencing all
Pledged Interests, together with all other Pledged Collateral held by the
Collateral Trustee hereunder, and execute and deliver to the Company such
documents as the Company shall reasonably request to evidence such termination
or release.

         SECTION 2.6.      Security Interest Absolute. All rights of the
Collateral Trustee and the security interests granted to the Collateral Trustee
hereunder, and all obligations of the Company hereunder, shall be absolute and
unconditional, irrespective of

                  (a)      any lack of validity or enforceability of any of the
         Secured Debt Documents,

                  (b)      the failure of any Secured Party or any holder of any
         Secured Obligation

                           (i)      to assert any claim or demand or to enforce
                  any right or remedy against the Company, any other Obligor or
                  any other Person under the provisions of any of the Secured
                  Debt Documents or otherwise, or

                                       5


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

                  (c)      any change in the time, manner or place of payment
         of, or in any other term of, all or any of the Secured Obligations or
         any other extension, compromise or renewal of any Secured Obligation of
         the Company or any other Obligor,

                  (d)      any reduction, limitation, impairment or termination
         of any Secured Obligations of the Company 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 Company 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 Secured Obligations
         of the Company, 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
         any of the Secured Debt Documents,

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

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

         SECTION 2.7.      [Intentionally Omitted.]

         SECTION 2.8.      Waiver of Subrogation. Until such time as the Secured
Obligations have been indefeasibly paid in full and discharged and all
commitments to extend credit under all Credit Facilities the Indebtedness under
which constitutes Priority Lien Debt shall have been permanently terminated or
expired, the Company hereby irrevocably waives any claim or other rights which
it may now or hereafter acquire against the Company or any other Obligor that
arise from the existence, payment, performance or enforcement of the Company's
obligations under this Pledge Agreement or any other Secured Debt Document,
including any right of subrogation, reimbursement, exoneration, or
indemnification, any right to participate in any claim or remedy of the
Collateral Trustee against the Company or any other Obligor or any collateral
which the Collateral Trustee 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 Company 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 Company in violation of the preceding sentence and
the Secured Obligations shall not have been indefeasibly paid in full, in cash,
and all commitments to extend credit under all Credit Facilities the
Indebtedness under which constitutes Priority Lien Debt

                                       6


shall have not been permanently terminated or expired, such amount shall be
deemed to have been paid to the Company for the benefit of, and held in trust
for, the Collateral Trustee, and shall forthwith be paid to the Collateral
Trustee to be credited and applied upon the Secured Obligations, whether matured
or unmatured, in accordance with the terms of the Collateral Trust Agreement.
The Company acknowledges that it will receive direct and indirect benefits from
the financing arrangements contemplated by the Secured Debt Documents and that
the waiver set forth in this Section is knowingly made in contemplation of such
benefits.

                                  ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

         SECTION 3.1.      Warranties, etc. The Company represents and warrants
unto the Collateral Trustee and each Secured Party, as at the date of each
pledge and delivery hereunder (including each pledge and delivery of Pledged
Interests) by the Company to the Collateral Trustee of any Pledged Collateral,
as set forth in this Article.

         SECTION 3.1.1     Ownership, No Liens, etc. The Company is the legal
and beneficial owner of, and has good and marketable title to (and has full
right and authority to pledge and assign) such Pledged Collateral, free and
clear of all liens, security interests, options, or other charges or
encumbrances, except any lien or security interest granted pursuant hereto in
favor of the Collateral Trustee.

         SECTION 3.1.2     Valid Security Interest. The delivery of such Pledged
Collateral to the Collateral Trustee is effective to create a valid, perfected,
first priority or second priority, as the case may be, security interest in such
Pledged Collateral and all proceeds thereof, securing the Secured Obligations,
subject in each case to the provisions of Section 3.4 of the Collateral Trust
Agreement. No filing or other action will be necessary to perfect or protect
such security interest.

         SECTION 3.1.3     As to Pledged Interests. In the case of any Pledged
Interests constituting such Pledged Collateral, all of such Pledged Interests
are duly authorized and validly issued, fully paid, and non-assessable, and
constitute all of the issued and outstanding shares of capital stock entitled to
vote in the election of the Board of Directors of each Pledged Share Issuer.

         SECTION 3.1.4     Nature of Membership Interests. No right, title and
interest of the Company in the Pledged Interests Issuers are represented by a
certificate of interest or instrument, except such certificates or instruments,
if any, as have been delivered to the Collateral Trustee and are held in its
possession, together with transfer documents as required in this Pledge
Agreement (and the Company covenants and agrees that any such certificates or
instruments hereafter received by the Company with respect to any of the Pledged
Collateral will be held in trust for the Collateral Trustee and promptly
delivered to the Collateral Trustee).

                                       7


                                   ARTICLE IV
                                    COVENANTS

         SECTION 4.1.      Protect Collateral; Further Assurances, etc. The
Company will not sell, assign, transfer, pledge, or encumber in any other manner
the Pledged Collateral (except in favor of the Collateral Trustee hereunder and
as otherwise expressly permitted by the Secured Debt Documents). The Company
will warrant and defend the right and title herein granted unto the Collateral
Trustee in and to the Pledged Collateral (and all right, title, and interest
represented by the Pledged Collateral) against the claims and demands of all
Persons whomsoever. The Company agrees that at any time, and from time to time,
at the expense of the Company, the Company will promptly execute and deliver all
further instruments, and take all further action, that may be necessary or
desirable, or that the Collateral Trustee or any Secured Debt Representative may
reasonably request, in order to perfect and protect any security interest
granted or purported to be granted hereby or to enable the Collateral Trustee to
exercise and enforce its rights and remedies hereunder with respect to any
Pledged Collateral. The Company hereby authorizes the Collateral Trustee to
cause the filing of any financing statement that (i) indicates the Pledged
Collateral and (ii) contains any other information required by Section 5 of
Article 9 of the Uniform Commercial Code of the jurisdiction wherein such
financing statement or amendment is filed regarding the sufficiency or filing
office acceptance of any financing statement or amendment, including whether the
Company is an organization, the type of organization and any organization
identification number issued to the Company; provided that this sentence shall
not be interpreted as requiring the Collateral Trustee to file any such
financing statements, continuation statements or other instruments.

         SECTION 4.2.      Certificates, etc. The Company agrees that all
certificates evidencing Pledged Interests, if any, delivered by the Company
pursuant to this Pledge Agreement will be accompanied by duly executed undated
blank stock powers, or other equivalent instruments of transfer reasonably
acceptable to the Collateral Trustee. The Company will, from time to time upon
the reasonable request of the Collateral Trustee or any Secured Debt
Representative, promptly deliver to the Collateral Trustee such stock powers,
instruments, and similar documents, reasonably satisfactory in form and
substance to the Collateral Trustee, with respect to the Pledged Collateral as
the Collateral Trustee or any Secured Debt Representative may reasonably request
and will, from time to time upon the reasonable request of the Collateral
Trustee after the occurrence of any Actionable Default, promptly transfer any
Pledged Interests into the name of any nominee designated by the Collateral
Trustee.

         SECTION 4.3.      Continuous Pledge. Subject to Section 2.5, the
Company will, at all times, keep pledged to the Collateral Trustee pursuant
hereto all Pledged Interests and all other shares of capital stock constituting
Pledged Collateral, all Distributions with respect thereto, and all other
Pledged Collateral and other securities, instruments, proceeds, and rights from
time to time received by or distributable to the Company in respect of any
Pledged Collateral.

         SECTION 4.4.      Voting Rights. The Company agrees after any
Actionable Default shall have occurred and be continuing and the Collateral
Trustee has notified the Company of the Collateral Trustee's intention to
exercise its voting power under this Section 4.4

                                       8


                           (i)      the Collateral Trustee may exercise (to the
                  exclusion of the Company) the voting power and all other
                  incidental rights of ownership with respect to any Pledged
                  Interests or other shares of capital stock constituting
                  Pledged Collateral and the Company hereby grants the
                  Collateral Trustee an irrevocable proxy, exercisable under
                  such circumstances, to vote the Pledged Interests and such
                  other Pledged Collateral; and

                           (ii)     promptly to deliver to the Collateral
                  Trustee such additional proxies and other documents as may be
                  necessary to allow the Collateral Trustee to exercise such
                  voting power.

The Collateral Trustee agrees that unless an Actionable Default shall have
occurred and be continuing and the Collateral Trustee shall have given the
notice referred to in this Section 4.4, the Company shall have the exclusive
voting power with respect to any membership interests (including any of the
Pledged Interests) constituting Pledged Collateral and the Collateral Trustee
shall, upon the written request of the Company, promptly deliver such proxies
and other documents, if any, as shall be reasonably requested by the Company
which are necessary to allow the Company to exercise voting power with respect
to any such membership interests (including any of the Pledged Interests)

granted pursuant to this Section is irrevocable and coupled with an interest.

         SECTION 5.2.      Collateral Trustee May Perform. If the Company fails

the Collateral Trustee incurred in connection therewith shall be payable by the

         SECTION 5.3.      Collateral Trustee's Rights and Duties Subject to
Collateral Trust Agreement. Notwithstanding anything to the contrary contained
in this Pledge Agreement, in acting under and by virtue of this Pledge
Agreement, the Collateral Trustee shall be entitled to all of the rights,

the rights and duties of the Collateral Trustee hereunder are subject in all
respects to the terms, conditions and limitations set forth in the Collateral
Trust Agreement (including, without limitation, the provisions of Article 5
thereof), reference to which is made for all purposes; provided, however, that
any forbearance by the Collateral Trustee in exercising any right or remedy
available to it under the Collateral Trust Agreement shall not give rise to a
defense on the part of the Company with respect to the Collateral Trustee's
exercise of any right or remedy pursuant to this Pledge Agreement or as
otherwise afforded by applicable law.

                                   ARTICLE VI
                                    REMEDIES

         SECTION 6.1.      Certain Remedies. If an Actionable Default shall have
occurred and be continuing:

                  (a)      The Collateral Trustee may exercise in respect of the
         Pledged 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 Pledged Collateral) and also may, without
         notice except as specified below, sell the Pledged Collateral or any
         part thereof in one or more parcels at public or private sale, at any
         of the Collateral Trustee's offices or elsewhere, for cash, on credit
         or for future delivery, and upon such other terms as the Collateral
         Trustee may deem commercially reasonable in each case subject to the
         terms and provisions of the Collateral Trust Agreement. The Company
         agrees that, to the extent notice of sale shall be required by law, at
         least ten days' prior notice to the Company 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 Collateral Trustee shall
         not be obligated to make any sale of Pledged Collateral regardless of
         notice of sale having been given. The Collateral Trustee 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 Collateral Trustee may, in each case subject to
         the terms and provisions of the Collateral Trust Agreement,

                                       10


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

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

                           (iii)    enforce collection of any of the Pledged
                  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 Company's name to allow collection of the
                  Pledged Collateral,

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

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

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

                  (a)      execute and deliver, and cause each Pledged Interests
         Issuer of the Pledged 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 advisable to register such Pledged 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 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 Pledged
         Collateral under the state securities or "Blue Sky" laws and to obtain
         all necessary governmental approvals for the sale of the Pledged
         Collateral;

                  (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

                                       11


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

         SECTION 6.3.      Compliance with Restrictions. The Company agrees that
in any sale of any of the Pledged Collateral whenever an Actionable Default
shall have occurred and be continuing, the Collateral Trustee 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 Pledged 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 Company 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 Collateral Trustee
be liable nor accountable to the Company for any discount allowed by the reason
of the fact that such Pledged Collateral is sold in compliance with any such
limitation or restriction.

         SECTION 6.4.      Application of Proceeds. All cash proceeds received
by the Collateral Trustee in respect of any sale of, collection from, or other
realization upon, all or any part of the Pledged Collateral shall thereafter be
applied in accordance with Section 3.4 of the Collateral Trust Agreement.

         SECTION 6.5.      Indemnity and Expenses.

                  (a)      The Company agrees to indemnify the Collateral
         Trustee from and against any and all Indemnified Liabilities with
         respect to the execution, delivery, performance, administration or
         enforcement of this Pledge Agreement to the extent provided in Section
         7.8 of the Collateral Trust Agreement.

                  The Company agrees to reimburse the Collateral Trustee for all
         costs, fees and expenses relating to this Pledge Agreement to the
         extent provided in Section 7.7 of the Collateral Trust Agreement.

                                   ARTICLE VII
                            MISCELLANEOUS PROVISIONS

         SECTION 7.2.      Amendments, etc. No amendment to or waiver of any

signed by the Collateral Trustee in accordance

                                       12

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 Collateral Trustee may
from time to time, at its option, perform any act which the Company agrees
hereunder to perform and which the Company 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 Actionable
Default) and the Collateral Trustee may from time to time take any other action
which the Collateral Trustee or any Secured Debt Representative reasonably deems
necessary for the maintenance, preservation or protection of any of the Pledged
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

to the extent of such prohibition or invalidity, without invalidating the

YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW

OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, THE COMPANY HEREBY
IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS PLEDGE
AGREEMENT.

         SECTION 7.9.      Waiver of Jury Trial. THE COLLATERAL TRUSTEE AND THE
COMPANY 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
