Without limiting the generality of the foregoing, the Administrative Agent shall
be under no obligation to sell any of the Pledged Collateral or otherwise to
take any steps necessary to preserve the value of any of the Pledged Collateral

it is authorized to receive and retain pursuant to Section 4 below. Upon the
occurrence and during the continuance of an Event of Default and the
Administrative Agent’s election to exercise its rights and remedies hereunder
with respect to the Pledged Collateral in consequence thereof, all rights of
Pledgor to exercise the voting and other consensual rights which it would
otherwise be entitled to exercise pursuant to this Section 3 shall cease, and

the benefit of the Secured Parties, who shall thereupon have the sole right to
exercise such voting and other consensual rights, and any and all proxies
theretofore executed by the Administrative Agent shall terminate and thereafter
be null and void and of no effect whatsoever.
4.Collection of Dividend Payments. During the term of this Pledge Agreement, and
so long as there shall not occur or exist any Event of Default, each Pledgor
shall have the right to receive and retain any and all dividends and other

Pledgor or any Pledged Subsidiary) or any agreement among any Pledgor’s or any
Pledged Subsidiary’s shareholders or members; (f) this Pledge Agreement has been
duly authorized, executed and delivered by such Pledgor and constitutes a legal,

indenture, instrument or applicable law by which any Pledgor or any Pledged
Subsidiary is bound or to which any Pledgor or any Pledged Subsidiary is subject
(except such Pledgor makes no representation or warranty about the

regulations governing the sale or exchange of securities), except in the case of
clause (ii) to the extent that could not reasonably be expected to have a
Material Adverse Effect; (h) no consent, filing, approval, registration or
recording is required (x) for the pledge by such Pledgor of the Pledged

Pledged Collateral that is not currently certificated becomes certificated,
deliver all certificates or other documents evidencing or representing the
Pledged Collateral to the Administrative Agent, accompanied by powers, all in

Pledged Collateral which is not currently certificated, with any certificates,
instruments or other writings, unless the relevant Pledged Subsidiary has
complied with the provisions of Section 6(d) of this Pledge Agreement.
8.Irrevocable Authorization and Instruction to Pledged Subsidiaries. To the
extent that any portion of the Pledged Collateral may now or hereafter consist

Pledgor irrevocably authorizes and instructs each Pledged Subsidiary to comply
with any instruction received by such Pledged Subsidiary from the Administrative
Agent with respect to such Pledged Collateral without any other or further
instructions from or consent of any Pledgor, and each Pledgor agrees that each

12.Registration. If the Administrative Agent determines that it is required to
register under or otherwise comply in any way with the Securities Act of 1933,
as amended (the “Securities Act”) or any similar federal or state law, with
respect to the securities included in the Pledged Collateral prior to sale
thereof by the Administrative Agent, then upon the occurrence and during the
continuation of an Event of Default, Pledgors will use their best efforts to
cause any such registration to be effectively made, at no expense to the
Administrative Agent, and to continue such registration effective for such time
as may be reasonably necessary in the reasonable opinion of the Administrative
Agent, and will reimburse the Administrative Agent for any documented
out-of-pocket expense incurred by the Administrative Agent, including documented

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

fees and charges of one counsel and one local counsel and applicable regulatory
counsel in each appropriate jurisdiction and accountants’ fees and expenses, in
connection therewith.
13.Consent. Each Pledgor hereby consents that from time to time, before or after
the occurrence or existence of any Default or Event of Default, with or without
notice to or assent from any Pledgor, any other security at any time held by or
available to the Administrative Agent for any of the Secured Obligations may be
exchanged, surrendered, or released, and any of the Secured Obligations may be
changed, altered, renewed, extended, continued, surrendered, compromised, waived
or released, in whole or in part, as the Administrative Agent may see fit, and
each Pledgor shall remain bound under this Pledge Agreement and under the other
Loan Documents notwithstanding any such exchange, surrender, release,
alteration, renewal, extension, continuance, compromise, waiver or inaction,
extension of further credit or other dealing.
14.Remedies Upon Default. Upon the occurrence and during the continuation of any
Event of Default, (i) the Administrative Agent shall have, in addition to any
other rights given by law or the rights given hereunder or under each of the
other Loan Documents, all of the rights and remedies with respect to the Pledged
Collateral of a secured party under the UCC and (ii) the Administrative Agent
may cause all or any part of the Equity Interests held by it to be transferred
into its name or the name of its nominee or nominees. In addition, upon the
occurrence and during the continuation of an Event of Default, the
Administrative Agent may sell or cause the Pledged Collateral, or any part
thereof, which shall then be or shall thereafter come into the Administrative
Agent’s possession or custody, to be sold at any broker’s board or at public or
private sale, in one or more sales or lots, at such price as the Administrative
Agent may deem best, and for cash or on credit or for future delivery, and the
purchaser of any or all of the Pledged Collateral so sold shall thereafter hold
the same absolutely, free from any claim, encumbrance or right of any kind
whatsoever of any Pledgor or arising through any Pledgor. If any of the Pledged
Collateral is sold by the Administrative Agent upon credit or for future
delivery, the Administrative Agent shall not be liable for the failure of the
purchaser to pay the same and in such event The Administrative Agent may resell
such Pledged Collateral. Unless the Pledged Collateral threatens to decline
speedily in value or is or becomes of a type sold on a recognized market, the
Administrative Agent will give Pledgors reasonable notice of the time and place
of any public sale thereof, or of the time after which any private sale or other
intended disposition is to be made. Any sale of the Pledged Collateral conducted
in conformity with reasonable commercial practices of banks, insurance companies
or other financial institutions disposing of property similar to the Pledged
Collateral shall be deemed to be commercially reasonable. Any requirements of
reasonable notice shall be met if such notice is mailed to Pledgors, as provided
in Section 27 below, at least ten (10) days before the time of the sale or
disposition. Any other requirement of notice, demand or advertisement for sale
is, to the extent permitted by applicable law, waived. The Administrative Agent
may, in its own name, or in the name of a designee or nominee, buy at any public
sale of the Pledged Collateral and, if permitted by applicable law, buy at any
private sale thereof. Pledgors will pay to the Administrative Agent on demand
all documented out-of-pocket expenses (including court costs and the fees and
charges of one counsel and one local counsel and applicable regulatory counsel
in each appropriate jurisdiction) of, or incident to, the enforcement of any of
the provisions hereof and all other charges due against the Pledged Collateral,
including taxes, assessments or Liens upon the Pledged Collateral and any
documented out-of-pocket expenses, including transfer or other taxes, arising in
connection with any sale, transfer or other disposition of Pledged Collateral.
The Administrative Agent shall apply the cash proceeds actually received from
any sale or other disposition to the reasonable expenses of retaking, holding,
preparing for sale, selling and the like, to the fees and charges of one counsel
and one local counsel and applicable regulatory counsel in each appropriate
jurisdiction and all travel and other documented out-of-pocket expenses which
may be incurred by the Administrative Agent in attempting to collect the Secured
Obligations or to enforce this Pledge Agreement or in the prosecution or defense
of any action or proceeding related to the subject matter of this Pledge
Agreement; and then to the Secured Obligations in the manner authorized by the
Credit Agreement.
15.Redemption; Marshaling. Each Pledgor agrees that the Administrative Agent
shall not be required to marshal any present or future security (including this
Pledge Agreement and the Pledged Collateral pledged hereunder) for, or
guaranties of, the Secured Obligations or any of them, or to resort to such
security or guaranties in any particular order; and all of the Administrative
Agent’s rights hereunder and in respect of such security and guaranties shall be
cumulative and in addition to all other rights, however existing or arising. To
the fullest extent that it lawfully may, each Pledgor hereby agrees that it will
not invoke any law relating to the marshaling of collateral that might cause
delay in or impede the enforcement of The Administrative Agent’s rights under
this Pledge Agreement or under any other instrument evidencing any of the
Secured Obligations or under which any of the Secured Obligations is outstanding
or by which any of the Secured Obligations is secured or guaranteed, and to the
fullest extent that it lawfully may, each Pledgor hereby irrevocably waives the
benefits of all such laws.
16.Term. This Pledge Agreement shall become effective only when accepted by the
Administrative Agent and, when so accepted, shall constitute a continuing
agreement and shall remain in full force and effect until all of the Secured
Obligations have been fully and finally paid, satisfied and discharged, at which
time this Pledge Agreement shall terminate and the Administrative Agent shall
deliver to Pledgors, at Pledgors’ expense, (i) such of the Pledged Collateral as
shall not have been sold or otherwise applied pursuant to this Pledge Agreement
and (ii) such termination statements and other release documents as may be
requested by Pledgors to evidence the termination of the Administrative Agent’s
security interest in the Pledged Collateral, Notwithstanding the foregoing, in
no event shall any termination of this Pledge Agreement terminate any indemnity
set forth in this Pledge Agreement or any of the other Loan Documents, all of
which indemnities shall survive any termination of this Pledge Agreement or any
of the other Loan Documents in accordance with their respective terms.
17.Rules and Construction. The singular shall include the plural and vice versa,
and any gender shall include any other gender as the text shall indicate. All
references to “including” shall mean “including, without limitation.” Whenever
in this Pledge Agreement the words “Equity Interest” or “Equity Interests” or
other similar words or phrases are used in connection with a Person referring to
equity ownership interests in such Person, such word or phrase shall also be
deemed to include a reference to capital stock and limited liability company
membership interests, each reference to a “corporation” shall also be deemed to
include a reference to a limited liability company and vice versa, each
reference to “shareholders” of a Person shall also be deemed to include a
reference to members and vice versa and each reference to “certificate of
incorporation” or “articles of incorporation” or “bylaws” shall also be deemed

or other constituent documents of a limited liability company and vice versa.

together with the Credit Agreement and other Loan Documents, constitutes and

respective successors and assigns, except that no Pledgor shall be permitted to
assign this Pledge Agreement, any Pledge Joinder Agreement or any interest
herein or therein or in the Collateral, or any part thereof or interest therein,
or otherwise pledge, encumber or grant any option with respect to the
Collateral, or any part thereof, or any cash or property held by the
Administrative Agent as Collateral under this Pledge Agreement. Without limiting
the generality of the foregoing sentence of this Section 19, any Lender 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); 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 Lender herein or otherwise, subject however, to the

such other powers, instruments, financing statements, certificates, legal
opinions and other documents, and will take all such other action as the
Administrative Agent may reasonably request from time to time, in order to carry
out the provisions and purposes hereof, including delivering to the
Administrative Agent, if requested by the Administrative Agent, irrevocable
proxies with respect to the Equity Interests constituting Pledged Collateral in
form reasonably satisfactory to the Administrative Agent (subject to Pledgors’
voting rights under Section 3 hereof). Until receipt thereof, this Pledge
Agreement shall constitute each Pledgor’s proxy to the Administrative Agent or
its nominee to vote all shares of the Equity Interests constituting Pledged
Collateral then registered in such Pledgor’s name (subject to Pledgors’ voting
rights under Section 3 hereof).

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

23.Severability. The provisions of this Pledge Agreement are independent of and
separable from each other. If any provision hereof shall for any reason be held

Agreement shall be construed as if such invalid or unenforceable provision had
never been contained herein.

counterparts each of which when so executed and delivered shall be deemed an
original, and it shall not be necessary in making proof of this Pledge Agreement

Collateral shall not constitute a condition of any demand, suit or proceeding
for payment or collection of the Secured Obligations.

additional Pledged Interests, including any Pledged Interests issued by any
Subsidiary not listed on Annex A hereto which are required to be subject to a

within the time period specified in such Section or elsewhere in the Credit
Agreement with respect to such Additional Interests; provided, however, that the
failure to comply with the provisions of this Section 26 shall not impair the
Lien on Additional Interests conferred hereunder.
27.Notices. All notices, requests and demand to or upon either party hereto
shall be given in the manner and become effective as stipulated in the Credit
Agreement.
28.Joinder. Each Person who shall at any time execute and deliver to the

and collaterally assigned and pledged to the Administrative Agent for the
benefit of the Secured Parties all Pledged Interest which it has as of such date
of delivery or thereafter acquires any interest or the power to transfer, and
all references herein and in the other Loan Documents to the Pledgors or to the
parties to this Pledge Agreement shall be deemed to include such Person as a
Pledgor hereunder. Each Pledge Joinder Agreement shall be accompanied by the
Supplemental Annex A referred to therein, appropriately completed with
information relating to the Pledgor executing such Pledge Joinder Agreement and
its property. Annex A attached hereto shall be deemed amended and supplemented
without further action by such information reflected on the Supplemental Annex

29.Pledgors’ Obligations Not Affected. The obligations of Pledgors hereunder
shall remain in full force and effect without regard to, and shall not be
impaired by (a) any bankruptcy, insolvency, reorganization, arrangement,
readjustment, composition, liquidation or the like of any Pledgor; (b) any
exercise or nonexercise, or any waiver, by the Administrative Agent of any
right, remedy, power or privilege under or in respect of any of the Secured
Obligations or any security thereof (including this Pledge Agreement); (c) any
amendment to or modification of the Credit Agreement, the other Loan Documents
or any of the Secured Obligations; (d) any amendment to or modification of any
instrument (other than this Pledge Agreement) securing any of the Secured
Obligations; or (e) the taking of additional security for, or any guaranty of,
any of the Secured Obligations or the release or discharge or termination of any
security or guaranty for any of the Secured Obligations, whether or not any
Pledgor shall have notice or knowledge of any of the foregoing.
30.No Waiver, Etc. No act, failure or delay by the Administrative Agent shall
constitute a waiver of any of its rights and remedies hereunder or otherwise. No
single or partial waiver by the Administrative Agent of any Default or Event of
Default or right or remedy that the Administrative Agent may have shall operate
as a waiver of any other Default, Event of Default, right or remedy or of the
same. Default, Event of Default, right or remedy on a future occasion. Each
Pledgor hereby waives presentment, notice of dishonor and protest of all
instruments included in or evidencing any of the Secured Obligations or the
Pledged Collateral, and any and all other notices and demands whatsoever (except
as expressly provided herein).
31.Section Headings. The section headings herein are for convenience of
reference only, and shall not affect in any way the interpretation of any of the
provisions hereof.
32.Administrative Agent Appointed Attorney-In-Fact. Each Pledgor hereby
constitutes and appoints the Administrative Agent, with full power of
substitution, such Pledgor’s attorney-in-fact for the purpose of carrying out
the provisions of this Pledge Agreement and taking any action and executing any
instrument which the Administrative Agent may reasonably deem necessary or
advisable to accomplish the purposes hereof, which appointment is coupled with
an interest and is irrevocable. Without limiting the generality of the
foregoing, the Administrative Agent shall have the power to arrange for the
transfer, upon the occurrence and during the continuation of an Event of
Default, of any of the Pledged Collateral on the books of any or all of Pledged
Subsidiaries to the name of the Administrative Agent or the Administrative
Agent’s nominee. Pledgors agree to jointly and severally indemnify and save the
Administrative Agent and Secured Parties harmless from and against any liability
or damage that the Administrative Agent or any Secured Party may suffer or
incur, in the exercise or performance of any of the Administrative Agent’s or
any Secured Party’s powers and duties specifically set forth herein; provided
that such indemnity shall not be available to the extent that such liabilities
or damages (x) are determined by a court of competent jurisdiction by final and
nonappealable judgment to have resulted from the gross negligence or willful
misconduct of an indemnitee, (y) result from a claim brought by a Pledgor
against an indemnitee for breach in bad faith of such indemnitee’s obligations
hereunder, if a Pledgor has obtained a final and nonappealable judgment in its
favor on such claim as determined by a court of competent jurisdiction or (z)
arise out of, or in connection with, any proceeding that does not involve an act
or omission by a Pledgor or any of its Affiliates that is brought by an
indemnitee against any other indemnitee (other than any proceeding against any
indemnitee in its capacity or fulfilling its role as the Administrative Agent,
an Arranger, the L/C Issuer or any similar role).
33.Use of Loan Proceeds. Each Pledgor hereby represents and warrants to the
Administrative Agent that none of the loan proceeds heretofore and hereafter
received by it under the Credit Agreement are for the purpose of purchasing any
“margin stock” as that term is defined in either Regulation U promulgated by the
Board of Governors of the Federal Reserve System, or refinancing any
indebtedness originally incurred to purchase any such “margin stock.”
34.Waiver of Subrogation and Other Claims. Each Pledgor recognizes that the
Administrative Agent, in exercising its rights and remedies with respect to the
Pledged Collateral, may likely be unable to find one or more purchasers thereof
if, after the sale of the Pledged Collateral, a Pledged Subsidiary were, because
of any claim based on subrogation or any other theory, liable to any Pledgor on
account of the sale by the Administrative Agent of the Pledged Collateral in
full or partial satisfaction of the Secured Obligations or liable to any Pledgor
on account of any indebtedness owing to any Pledgor that is subordinated to any
or all of the Secured Obligations. Each Pledgor hereby agrees, therefore, that
if, in accordance with applicable law, the Administrative Agent sells any of the
Pledged Collateral in full or partial satisfaction of the Secured Obligations,
no Pledgor shall in such case have any right or claim against any Pledged
Subsidiary on account of any such subordinated indebtedness on the theory that
such Pledgor has become subrogated to any claim or right of the Administrative
Agent against such Pledged Subsidiary or on any basis whatsoever, and each
Pledgor hereby expressly waives and relinquishes all such rights and claims
against Pledged Subsidiaries.

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

ACCEPTANCE OF THIS PLEDGE AGREEMENT; NOTICE OF EXTENSIONS OF CREDIT, LOANS,
