SECTION 4.    COVENANTS OF DEBTORS.
(a)    Each Debtor agrees: (i) without limiting the generality of Section 10.4
of the Credit Agreement (but subject to any limitations and restrictions
contained therein), to pay all reasonable out-of-pocket expenses incurred by the
Administrative Agent (including, without limitation, the reasonable fees,
charges and disbursements of counsel) in the perfection and preservation of the
Collateral for the benefit of the Secured Parties or the Secured Parties’
interest therein and all out-of-pocket expenses incurred by the Administrative
Agent, any Lender or the LC Issuing Lender (including the fees, charges and

and exercise of its rights, powers, and remedies hereunder; (ii) to, at such
Debtor’s expense (but not to exceed the obligation under the preceding clause

Parties’ interest therein and/or the realization, enforcement and exercise of

3
83185781_6

--------------------------------------------------------------------------------

preservation, perfection or enforcement of any of its rights hereunder (in each
case, except as otherwise provided in the Credit Agreement). Notwithstanding the
foregoing or anything else to the contrary set forth in this Agreement or any
other Loan Document, the Administrative Agent shall not require that security
interests in the Pledged Interests in any First Tier Foreign Subsidiary be
perfected in any jurisdiction outside of the United States on the Closing Date.
(b)    Each Debtor agrees with regard to the Collateral that the Administrative
Agent for the benefit of the Secured Parties is authorized to file financing
statements in the name of such Debtor to perfect the Administrative Agent’s
security interest in Collateral. Each Debtor shall (x) deliver all certificates,
instruments or, to the extent requested by the Administrative Agent other
documents representing any Collateral to the Administrative Agent at such
location as the Administrative Agent shall from time to time designate by
written notice pursuant to Section 8 for its custody at all times until the
Termination Date, together with such instruments of assignment and transfer as
reasonably requested by the Administrative Agent, and (y) register and cause to
be registered the security interest of the Administrative Agent in the
Collateral on the registration books of the applicable Pledged Issuer; provided
that, to the extent the applicable Debtor does not control the applicable
Pledged Issuer, it shall use commercially reasonable efforts to register and
cause to be registered the security interest of the Administrative Agent in the
Collateral on the registration books of such Pledged Issuer.
(c)    Without the prior consent of the Administrative Agent, no Pledged
Interest that, as of the date hereof (i) does not constitute a “security” within
the meaning of Article 8 of the New York Uniform Commercial Code (“Article 8”)
and (ii) is not represented or evidenced by certificates or instruments, shall,
after the date hereof, constitute a “security” within the meaning of Article 8,
unless (x) such Pledged Interest is of a corporation, (y) such Pledge Interest
becomes represented or evidenced by a certificate or instrument and such
certificate or instrument is delivered to the Administrative Agent (together
with such instruments of assignment and transfer as reasonably requested by the
Administrative Agent) or (x) the Debtor that pledged such Pledged Interest
hereunder, the issuer of such Pledged Interest and the Administrative Agent
enter into a control agreement with respect to such Pledged Interest (in form
and substance reasonably satisfactory to the Administrative Agent).
SECTION 5.    REMEDIES.
(a)    Upon the occurrence of and during the continuance of any Event of
Default, the Administrative Agent, on behalf of the Secured Parties, shall have
all rights, powers, privileges and remedies granted to a secured party upon
default under the Uniform Commercial Code or otherwise provided by law (subject
to the Law of any foreign jurisdiction in the case of Pledged Interests in a
foreign Pledged Issuer), including, without limitation, the right (i) to
transfer all or any part of the Collateral into the name of the Administrative
Agent or its nominee, (ii) to contact all Persons obligated to any Debtor on any
Collateral and to instruct such Persons to deliver all Collateral directly to
the Administrative Agent, and (iii) to sell, lease, license or otherwise

4
83185781_6

--------------------------------------------------------------------------------

dispose of any or all Collateral, all of which may be exercised with or, if
allowed by Law, without notice to any Debtor. All rights, powers, privileges and
remedies of the Administrative Agent may be exercised at any time by the
Administrative Agent and from time to time after the occurrence of and during
the continuance of an Event of Default, are cumulative and not exclusive, and
shall be in addition to any other rights, powers or remedies provided by Law,
equity or set forth elsewhere in this Agreement or the other Loan Documents. No
delay, failure or discontinuance of the Administrative Agent in exercising any
right, power, privilege or remedy hereunder shall affect or operate as a waiver
of such right, power, privilege or remedy; nor shall any single or partial
exercise of any such right, power, privilege or remedy preclude, waive or
otherwise affect any other or further exercise thereof or the exercise of any
other right, power, privilege or remedy. Any waiver, permit, consent or approval
of any kind by the Administrative Agent or any Secured Party of any default
hereunder, or any such waiver of any provisions or conditions hereof, must be
made in accordance with Section 10.1 of the Credit Agreement.
(b)    The Debtors recognize that the Administrative Agent may be unable, after
the occurrence and during the continuance of any Event of Default, to effect a
public sale of any or all the Pledged Interests by reason of certain
prohibitions contained in the Securities Act of 1933, as amended (the
“Securities Act”) and applicable state securities law or otherwise, and may be
compelled to resort to one or more private sales thereof to a restricted group
of purchasers that will be obligated to agree, among other things, to acquire
such securities for their own account for investment and not with a view to the
distribution or resale thereof. The Debtors acknowledge and agree that any such
private sale may result in prices and other terms less favorable than if such
sale were a public sale and, notwithstanding such circumstances, agree that any
such private sale shall be deemed to have been made in a commercially reasonable
manner. The Administrative Agent shall be under no obligation to delay sale of
any of the Pledged Interests for the period of time necessary to permit any
Subsidiary to register such securities for public sale under the Securities Act,
or under applicable state securities law, even if such Subsidiary would agree to
do so.
(c)    If an Event of Default has occurred and is continuing: (i) and unless
otherwise agreed to by Administrative Agent, Debtor will deliver to the
Administrative Agent, no later than one Business Day following the receipt
thereof, any dividends, distributions or other Collateral it may receive from
time to time, and, until so delivered, shall hold all such items of payment in
trust for the Secured Parties separate from the funds and other property of any
Debtor; (ii) except to the extent permitted by the Credit Agreement, no Debtor
will dispose of any Collateral except on terms approved by the Administrative
Agent in advance in writing; (iii) at the Administrative Agent’s request, each
Debtor will assemble and deliver all Collateral of such Debtor not already in
the possession of the Administrative Agent, and books and records pertaining
thereto, to the Administrative Agent at a reasonably convenient place designated
by the Administrative Agent; and (iv) upon notice to such Debtor by the
Administrative Agent, all rights of such Debtor to exercise or refrain from
exercising voting or other consensual rights in respect of the Collateral

5
83185781_6

--------------------------------------------------------------------------------

shall cease and all such rights shall thereupon become vested in the
Administrative Agent who shall thereupon have the sole right to exercise or
refrain from exercising such voting and other consensual rights. Except as set
forth in clauses (i) and (iv) of the immediately preceding sentence, each Debtor
shall be entitled to exercise, in its reasonable judgment, but in a manner not
inconsistent with the terms of the Credit Agreement or any other Loan Document
(including this Agreement), the voting powers and all other incidental rights of
ownership with respect to any Collateral and (subject to each Debtor’s
obligation to deliver to the Administrative Agent certificated Pledged Interests
pursuant to Section 4(b)) to receive all dividends, distributions and other
Collateral.
(d)    EACH DEBTOR WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW (I) ANY NOTICE
OR HEARING PRIOR TO THE TAKING OF POSSESSION OR CONTROL BY THE ADMINISTRATIVE
AGENT OF ANY COLLATERAL, (II) THE POSTING OF ANY BOND OR SECURITY WHICH MIGHT BE
REQUIRED BY ANY COURT PRIOR TO ALLOWING THE ADMINISTRATIVE AGENT TO EXERCISE ANY
OF ITS RIGHTS OR REMEDIES, AND (III) THE BENEFIT OF ALL VALUATION, APPRAISEMENT
AND EXEMPTION LAWS.
SECTION 6.    DISPOSITION OF COLLATERAL. In disposing of Collateral hereunder,
the Administrative Agent may disclaim all warranties of title, possession, quiet
enjoyment and the like. Any proceeds of any disposition of any Collateral, or
any part thereof, shall be applied by the Administrative Agent toward the
payment of the Obligations in such order as set forth in Section 8.3 of the
Credit Agreement.
SECTION 7.    POWERS OF THE ADMINISTRATIVE AGENT. Each Debtor appoints the
Administrative Agent its true attorney in fact to perform any of the following
powers, which are coupled with an interest, are irrevocable until termination of
this Agreement and may be exercised from time to time by the Administrative
Agent’s officers and employees, or any of them: (a) to perform any obligation of
such Debtor hereunder in such Debtor’s name or otherwise; and (b) to do all acts
and things and execute all documents in the name of such Debtor or otherwise,
deemed by the Administrative Agent as necessary, proper or convenient in
connection with the preservation, perfection or enforcement of its rights
hereunder; provided that the Administrative Agent agrees not to exercise such
power of attorney unless an Event of Default has occurred and is continuing.
SECTION 8.    NOTICES. All notices, requests and demands required or permitted
hereunder shall be given (a) with respect to any Debtor, at the Company’s
address indicated in Section 10.2 of the Credit Agreement, and (b) with respect
to the Administrative Agent or any other Secured Party, at the Administrative
Agent’s address indicated in Section 10.2 of the Credit Agreement. All such
addresses may be modified, and all such notices shall be given and shall be
effective, as provided in Section 10.2 of the Credit Agreement for the giving
and effectiveness of notices and modifications of addresses thereunder.

--------------------------------------------------------------------------------

SECTION 9.    SUCCESSORS, ASSIGNMENT. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and to their respective permitted
successors and assigns; provided that no Debtor shall be permitted to assign any
of its rights, powers, duties or obligations under this Agreement or any other
interest herein without the prior written consent of the Administrative Agent.
Without limiting the generality of the foregoing sentence of this Section 9, any
Secured Party may assign to one or more Persons, or grant to one or more Persons
participations in or to, all or any part of its rights and obligations under the
Credit Agreement (to the extent permitted by the Credit Agreement) or any
Secured Cash Management Agreement or Secured Hedge Agreement (to the extent
permitted thereunder); and to the extent of any such assignment or participation
such other Person shall, to the fullest extent permitted by law, thereupon
become vested with all the benefits in respect thereof granted to such Secured
Party herein or otherwise, subject however, to the provisions of the Credit
Agreement, including, without limitation, Section 10.6 of the Credit Agreement.
SECTION 10.    SEVERABILITY OF PROVISIONS. Any provision of this Agreement which
is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective only to the extent of such prohibition or
unenforceability without invalidating the remainder of such provision or the
remaining provisions hereof or affecting the validity or enforceability of such
provision in any other jurisdiction.
SECTION 11.    GOVERNING LAW; JURISDICTION; ETC.
(a)    Governing Law. This Agreement and the other Loan Documents and any claim,

therein) and the transactions contemplated hereby and thereby shall be governed
by, and construed in accordance with, the law of the State of New York.
(b)    Submission to Jurisdiction. Each Debtor irrevocably and unconditionally
agrees that it will not commence any action, litigation or proceeding of any

otherwise, against the Administrative Agent, any Lender, the LC Issuing Lender
or any Related Party of the foregoing in any way relating to this Agreement or

agrees that a final judgment in any such action, litigation or proceeding shall
be conclusive and may be enforced in other jurisdictions by suit on the judgment
or in any other manner provided by Law.  Nothing in this

7
83185781_6

--------------------------------------------------------------------------------

Agreement or in any other Loan Document shall affect any right that the
Administrative Agent or any other Secured Party may otherwise have to bring any
action or proceeding relating to this Agreement or any other Loan Document
against any Debtor or its properties in the courts of any jurisdiction.
(c)    Waiver of Venue. Each Debtor irrevocably and unconditionally waives, to
the fullest extent permitted by Law, any objection that it may now or hereafter

relating to this Agreement or any other Loan Document in any court referred to
in subsection (b) of this Section. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by Law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.
(d)    Service of Process. Each party hereto irrevocably consents to service of
process in the manner provided for notices in Section 8. Nothing in this
Agreement will affect the right of any party hereto to serve process in any
other manner permitted by Law.
SECTION 12.    WAIVER OF JURY TRIAL. EACH PARTY HERETO (AND BY ACCEPTING THE
BENEFITS HEREOF, EACH SECURED PARTY) HEREBY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL
PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT
OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY
(WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A)

AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS IN THIS SECTION.
SECTION 13.    REINSTATEMENT. Each Debtor agrees that this Agreement shall
continue to be effective or be reinstated, as the case may be, at any time

any of the Obligations is rescinded or must be restored for any reason, or is
repaid by any Secured Party in whole or in part in good faith settlement of any
pending or threatened avoidance claim.
SECTION 14.    SECURED CASH MANAGEMENT AGREEMENTS AND SECURED HEDGE AGREEMENTS.

8
83185781_6

--------------------------------------------------------------------------------

Administrative Agent, as applicable, and, in any such case, only to the extent
expressly provided in the Loan Documents. Notwithstanding any other provision of
this Agreement to the contrary, the Administrative Agent shall only be required
to verify the payment of, or that other satisfactory arrangements have been made
with respect to, the Obligations arising under any Secured Cash Management
Agreement and any Secured Hedge Agreement to the extent the Administrative Agent
has received written notice of such Obligations, together with such supporting
documentation as it may request, from the applicable Lender or Affiliate of a
Lender, as the case may be. Each Secured Party not a party to the Credit
Agreement that obtains the benefit of this Agreement shall be deemed to have
acknowledged and accepted the appointment of the Administrative Agent pursuant
to the terms of the Credit Agreement, and that with respect to the actions and
omissions of the Administrative Agent hereunder or otherwise relating hereto
that do or may affect such Secured Party, the Administrative Agent and each of
its Related Parties shall be entitled to all the rights, benefits and immunities
conferred under Section 9 of the Credit Agreement.
SECTION 15.    TERMINATION. Subject to reinstatement in accordance with Section
13, this Agreement will terminate upon the Termination Date. Upon such
termination, the Administrative Agent, at the request and sole expense of the
Debtors, shall execute and deliver to the Debtors all releases or other
documents reasonably necessary or desirable to evidence such termination. If any
Debtor or any Collateral shall be released by the Administrative Agent as
permitted by Section 9.11 of the Credit Agreement, then the Administrative
Agent, at the request and sole expense of such applicable Debtors, shall
promptly execute and deliver to such Debtors all releases or other documents
reasonably necessary or desirable for the release of such Debtors and/or the
Liens on Collateral created hereby.
SECTION 16.    COUNTERPARTS. This Agreement may be executed in counterparts (and
by different parties hereto in different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a
single contract. It shall not be necessary in making proof of this Agreement to
produce or account for more than one such counterpart executed by the party
against whom enforcement is sought. Delivery of an executed counterpart of a
signature page of this Agreement by facsimile or electronic (i.e., “pdf” or
“tif”) format shall be effective as delivery of a manually executed counterpart
of this Agreement.
SECTION 17.    ADDITIONAL INTERESTS. If any Debtor shall at any time acquire or
hold any additional Pledged Interests (other than any Excluded Collateral),
including any Pledged Interests issued by any Subsidiary not listed on Schedule
1 which are required to be subject to a Lien pursuant to this Agreement by the
terms hereof or of any provision of the Credit Agreement, but subject to any
limitations contained herein and therein and other than any Excluded Collateral
(any such shares being referred to herein as the “Additional Interests”), such
Debtor shall deliver to the Administrative Agent (i) a pledge agreement
supplement in the form of Annex 1 (each a “Pledge Agreement Supplement”) with
respect to such Additional Interests duly completed and executed by such Debtor
and (ii) any other document reasonably required in

9
83185781_6

--------------------------------------------------------------------------------

connection with such Additional Interests as described in Section 4(b). Each
Debtor shall comply with the requirements of this Section 17 within thirty days
of the acquisition of any such Additional Interests or such longer period as is
consented to by the Administrative Agent in its sole discretion or, in the case
of Additional Interests to which Section 6.12 of the Credit Agreement applies,
within the time period specified in such Section; provided that the failure to
comply with the provisions of this Section 17 shall not impair the Lien on
Additional Interests conferred hereunder.
SECTION 18.    ADDITIONAL DEBTORS. Pursuant to Section 6.12 of the Credit
Agreement, certain Subsidiaries that are created or acquired after the Closing
Date are required to enter into this Agreement as Debtors. Upon execution and
delivery by any such Subsidiary of a pledge joinder agreement in the form of
Annex 2 (each a “Pledge Joinder Agreement”), such Subsidiary shall become a
Debtor hereunder with the same force and effect as if originally named as a
Debtor herein. The execution and delivery of a Pledge Joinder Agreement adding
an additional Debtor as a party to this Agreement shall not require the consent
of any other Debtor hereunder. The rights and obligations of each Debtor
hereunder shall remain in full force and effect notwithstanding the addition of
any new Debtor as a party to this Agreement.
SECTION 19.    ENTIRE AGREEMENT. This Agreement and each Pledge Joinder
Agreement, together with the Credit Agreement and other Loan Documents,
constitutes and expresses the entire understanding between the parties hereto
with respect to the subject matter hereof, and supersedes all prior
negotiations, agreements and understandings, inducements, commitments or
conditions, express or implied, oral or written, except as contained in the Loan
Documents. The express terms hereof and of the Pledge Joinder Agreements control
and supersede any course of performance or usage of the trade inconsistent with
any of the terms hereof or thereof. Neither this Agreement nor any Pledge
Joinder Agreement nor any portion or provision hereof or thereof may be changed,
altered, modified, supplemented, discharged, canceled, terminated, or amended
orally or in any manner other than as provided in Section 10.1 of the Credit
Agreement.
