required annexes to this Agreement, as promptly as possible (and in no event more than ten (10)
days from the occurrence of any such Deferred Interests Triggering Event) as reasonably requested
by the Agent at such Pledgor’s expense in order to give the Agent a first priority security
interest (subject to Permitted Liens) in the Collateral represented by such Deferred Interests.
Immediately upon the occurrence of any Deferred Interests Triggering Event, a Lien on the Deferred
Interests consisting of Copyright Collateral, Patent Collateral, Trademark Collateral and all
Proceeds related thereto shall automatically be deemed to have attached in favor of the Agent
pursuant to this Section 2.3 without any further action by the Agent or any Pledgor and, on and
after the occurrence of such Deferred Interests Triggering Event, the Agent shall be authorized to
file financing statements under the Uniform Commercial Code describing the Collateral represented
by such Deferred Interests and each Pledgor, as applicable, shall take all necessary actions,
including, but not limited to, those required by Sections 4.9, 4.10 and 4.12 herein to complete any
required annexes to this Agreement, as promptly as possible (and in no event more than ten (10)
days from the occurrence of any such Deferred Interests Triggering Event) as reasonably requested
by the Agent at such Pledgor’s expense in order to give the Agent a first priority security
interest (subject to Permitted Liens) in the Collateral represented by such Deferred Interests. As
of the date on which a Lien on any Deferred Interests attaches pursuant to this Section 2.3, the
Pledgors shall be deemed to have reaffirmed the representations and warranties set forth in Article
III with respect to such Deferred Interests. Notwithstanding anything to the contrary set forth
herein, no Lien or security interest in favor of the Agent shall attach or be deemed to attach to,
and Agent agrees not to take any action to register, record or file any financing statement or
other evidence of a Lien or security interest in, any Patent Collateral, without the prior written
consent of the Pledgor that owns, licenses or has the right to use such Patent Collateral (except
that no such consent shall be required if a bankruptcy or insolvency proceeding shall have been
commenced by or against such Pledgor) if: (i) the attachment, registration, recordation or filing
of such Lien could reasonably be expected to (x) result in a breach or violation of any of the
terms or provisions of any license, permit or contractual agreement between such Pledgor and the
DOE or any other applicable governmental authority or (y) limit, invalidate or impair such
Pledgor’s right to maintain ownership of or license or right to use such Patent Collateral; or (ii)
such Patent Collateral includes classified information and the attachment, registration,
recordation or filing of such Lien on such Patent Collateral would constitute a breach or violation
of such Pledgor’s duty to maintain the confidentiality of such classified information.



(c) Without limiting Section 1.2, in no event shall the Collateral include, and no Pledgor
shall be deemed to have granted a security interest in any of such Pledgor’s rights or interests in
any license, contract or agreement to which such Pledgor is a party or any of its or interests
thereunder to the extent, but only to the extent, that such a grant would, under the terms of such
license, contract or agreement or otherwise, result in a breach of the terms of, or constitute a
default under any license, contract or agreement to which such Pledgor is a party (other than to
the extent that any such term would be rendered ineffective pursuant to the Uniform Commercial Code
or any other applicable law (including the Bankruptcy Code) or principles of equity);
provided that immediately upon the ineffectiveness, lapse or termination of any such
provision, the Collateral shall include, and such Pledgor shall be deemed to have granted a
security interest in, all such rights and interests as if such provision had never been in effect;
provided further that any Account or money or other amounts due or to become due to such
Pledgor under any such license, contract or agreement or any proceeds resulting from the sale or
other disposition by any Pledgor of any rights of such Pledgor under any such license, contract or
agreement shall at no time be excluded from the Collateral or the security interest granted by such
Pledgor hereunder in favor of the Agent.

otherwise dispose of, grant any option with respect to, or grant any Lien with respect to or
otherwise encumber any of the Deferred Interests or any interest therein.

Account to which all Pledgor-owned uranium and SWU Component in the Inventory shall be credited.
The balance of material credited to this Inventory Account shall be reconciled monthly, or more
often as may reasonably be requested by the Agent under the Credit Agreement, as part of the
Borrowing Base calculation.



ARTICLE III




REPRESENTATIONS AND WARRANTIES




Each Pledgor represents and warrants as follows:



3.1 Ownership of Collateral. Each Pledgor owns, or has valid rights as a lessee or
licensee, or the power to transfer or pledge with respect to, all Collateral (including without
limitation, all Deferred Interests which have become Collateral and all Deferred Interests which
would become Collateral if a Deferred Interests Triggering Event were to occur) purported to be
pledged by it hereunder, free and clear of any Liens, except for the Liens granted to the Agent for
the benefit of the Secured Parties pursuant to this Agreement and except for other Liens permitted
pursuant to Section 6.02 of the Credit Agreement (“Permitted Liens”). No security
agreement, financing statement or other public notice with respect to all or any part of the
Collateral (including without limitation, all Deferred Interests which have become Collateral and
all Deferred Interests which would become Collateral if a Deferred Interests Triggering Event were
to occur) is on file or of record in any government or public office, and no Pledgor has filed or
consented to the filing of any such statement or notice, except (i) Uniform Commercial Code
financing statements naming the Agent as secured party and Uniform Commercial Code financing
statements which have been terminated, (ii) security instruments filed in the U.S. Copyright Office
or the U.S. Patent and Trademark Office naming the Agent as secured party and (iii) as may be
otherwise permitted by the Credit Agreement.



3.2 Security Interests; Filings. This Agreement, together with (i) the filing of duly
completed and authorized Uniform Commercial Code financing statements (A) naming each Pledgor as
debtor, (B) naming the Agent as secured party, and (C) describing the Collateral, in the
jurisdictions set forth with respect to such Pledgor on Annex B hereto, (ii) when the Lien
on the Deferred Interests attaches pursuant hereto, the filing of duly completed and executed
assignments in the forms set forth as Exhibits B, C and D with the U.S.
Copyright Office or the U.S. Patent and Trademark Office, and, as appropriate, with regard to
federally registered Copyright Collateral, Patent Collateral and Trademark Collateral of each
Pledgor, as the case may be, (iii) the registration of transfer thereof to the Agent on the
issuer’s books or the execution by the issuer or securities intermediary (as applicable) of a
control agreement satisfying the requirements of Section 8-106 (or its successor provision) of the
Uniform Commercial Code with regard to uncertificated securities and Investment Property (other
than certificated securities) included in the Collateral, and (iv) the delivery to the Agent of all
certificated securities (including without limitation, certificated securities evidencing the
Equity Interests in Enrichment (and upon the consummation of a Restructuring Event, the Equity
Interests in any Intermediate Holdco) if and when the Lien on such Deferred Interests attaches) and
Instruments included in the Collateral together with undated stock powers or instruments of
transfer duly executed in blank, creates, and at all times shall constitute, a valid and perfected
security interest in and Lien upon the Collateral in favor of the Agent, for the benefit of the
Secured Parties, to the extent that Articles 8 and 9 of the Uniform Commercial Code are applicable
thereto, superior and prior to the rights of all other persons therein (except for Permitted
Liens), and no other or additional filings, registrations, recordings or actions are or shall be
necessary or appropriate in order to perfect or maintain the perfection and priority of such Lien
and security interest, other than actions required with respect to Collateral of the types excluded
from Articles 8 or 9 of the Uniform Commercial Code or from the filing requirements under Article 9
of the Uniform Commercial Code by reason of Sections 9-309, 9-310, 9-311 and 9-312 of the Uniform
Commercial Code and other than continuation statements required under the Uniform Commercial Code
(it being specifically noted that the Agent may at its option, but shall not be required to,
require, subject to the limitations set forth in Sections 3.10 and 4.11 hereof, that any bank or
other depository institution at which a Deposit Account is maintained enter into a written
agreement in form reasonably satisfactory to the Agent or take such other action as may be required
by law to perfect the security interest of the Agent in such Deposit Account and the funds
therein.)



3.3 Locations. Annex C lists, as to each Pledgor, (i) the addresses of its
chief executive office, each other place of business and for any Pledgor which is organized under
the laws of any state, its state of registration and registration I.D. number, (ii) the address of
each location where all original invoices, ledgers, chattel paper, Instruments and other records or
information evidencing or relating to the Collateral of such Pledgor are maintained, and (iii) the
address of each location at which any Inventory owned by such Pledgor is kept or maintained, in
each instance except for any new locations established in accordance with the provisions of Section
4.2 and except for Inventory which, in the ordinary course of business, is in transit (i) from a
supplier to a Pledgor, (ii) between locations listed on Annex C, or (iii) to customers or
processors. Except as may be otherwise noted therein, all locations identified in Annex C
are leased by the applicable Pledgor. No Pledgor presently conducts business under any prior or
other corporate or company name or under any trade or fictitious names, except as indicated beneath
its name on Annex C, and no Pledgor has entered into any contract or granted any Lien
within the past five (5) years under any name other than its legal name or a trade or fictitious
name indicated on Annex C. Each trade or fictitious name is a trade name and style (and
not the name of an independent corporation or other legal entity) by which a Pledgor may identify
and sell certain of its goods or services and conduct a portion of its business; all related
Accounts are owned solely by the applicable Pledgors and are subject to the Liens and other terms
of this Agreement; and in no event shall a Pledgor assert that products invoiced under the name of
any trade or fictitious name that are subject to a dispute with Customers are not subject to the
terms of this Agreement as though such trade or fictitious name did not exist.



3.4 Authorization; Consent. No authorization, consent or approval of, or declaration
or filing with, any Governmental Authority (including, without limitation, any notice filing with
state tax or revenue authorities required to be made by account creditors in order to enforce any
Accounts in such state) is required for the valid execution, delivery and performance by any
Pledgor of this Agreement, the grant by it of the Lien and security interest in favor of the Agent
provided for herein, or the exercise by the Agent of its rights and remedies hereunder, except for
(i) the filings and actions described in Section 3.2, (ii) in the case of Accounts owing from any
federal governmental agency or authority, the filing by the Agent of a notice of assignment in
accordance with the federal Assignment of Claims Act of 1940, as amended, (iii) in the case of
Equity Interests, such filings and approvals as may be required in connection with a disposition of
any such Collateral by laws affecting the offering and sale of securities generally, (iv) consents
and approvals, if any, required from the Department of Energy in its capacity as owner of the
plants in connection with the exercise of remedies hereunder under circumstances where none of the
Pledgors remained in control of such plants or in control of the portion of such plants where
Collateral is located, and (v) the other consents and approvals described in Section 8.16.



3.5 No Restrictions. There are no statutory or regulatory restrictions, prohibitions
or limitations on any Pledgor’s ability to grant to the Agent a Lien upon and security interest in
the Collateral (including without limitation, all Deferred Interests which have become Collateral
and all Deferred Interests which would become Collateral if a Deferred Interests Triggering Event
were to occur) pursuant to this Agreement or (except for the provisions of the federal Assignment
of Claims Act of 1940, as amended, or applicable regulatory limitations on access to U.S.
Government-owned facilities) the exercise by the Agent of its rights and remedies hereunder
(including any foreclosure upon or collection of the Collateral) except for the restrictions
described in Section 8.16, and there are no contractual restrictions, prohibitions or limitations
on any Pledgor’s ability so to grant such Lien and security interest or on the exercise by the
Agent of its rights and remedies hereunder (including any foreclosure upon or collection of the
Collateral).



3.6 Eligible Receivables.



(a) All Eligible Receivables owned by the Pledgors on the Effective Date constitute bona fide
Receivables arising in the ordinary course of business, the amount of which is actually owing and
payable to the Pledgors in the ordinary course of business. All such Eligible Receivables, net of
a bad debt reserve determined in accordance with generally accepted accounting principles, are
collectible in accordance with their terms.



(b) Each Eligible Receivable arising after the Effective Date shall be on the date of its
creation a good and valid account representing an undisputed bona fide indebtedness incurred or an
amount indisputably owed by the Customer therein named, for a fixed sum, to the extent, set forth
in the invoice relating thereto; none of the transactions underlying or giving rise to any such
Eligible Receivable shall violate any laws or regulations, and all documents relating to any such
Eligible Receivable shall be legally sufficient under such laws or related regulations applicable
to such Pledgor or Customer and are legally enforceable in accordance with their terms; no
agreement under which any deduction or offset of any kind, other than normal trade discounts and
discounts granted by a Pledgor in the ordinary course of its business in accordance with its
historical practices, have been granted by such Pledgor, at or before the time such Eligible
Receivable was created; all documents and agreements relating to such Eligible Receivable shall be
true and correct and in all respects what they purport to be; to the best of such Pledgor’s
knowledge, all signatures and endorsements that appear on all documents and agreements relating to
such Eligible Receivable are genuine and all signatories and endorsers shall have full capacity to
contract; and such Eligible Receivable is not evidenced by Chattel Paper or an Instrument, or if
so, such Chattel Paper or Instrument shall be duly endorsed to the order of the Agent and delivered
to the Agent to be held as Collateral hereunder.



3.7 Equity Interests. The Equity Interests required to be pledged hereunder (other
than the Equity Interests in Enrichment and any Intermediate Holdco) by each Pledgor that owns any
such Equity Interests consist of the number and type of shares of capital stock (in the case of
issuers that are corporations) or the percentage and type of other Equity Interests (in the case of
issuers other than corporation) as described beneath such Pledgor’s name in Annex A. As of
the date on which the Lien on the Deferred Interests attaches as provided in Section 2.3(b), the
Equity Interests in Enrichment (and upon the consummation of a Restructuring Event, the Equity
Interests in any Intermediate Holdco) required to be pledged hereunder will consist of the number
and type of shares of capital stock as described on Annex A to the Pledge Amendment (as
defined below) executed and delivered by the Parent or Intermediate Holdco, as applicable, to the
Agent pursuant to Section 5.1(b). All of the Equity Interests (including without limitation, all
Equity Interests constituting Deferred Interests) shall have been duly and validly issued and are
fully paid and nonassessable and not subject to any preemptive rights, warrants, options or similar
rights or restrictions in favor of third parties or any contractual or other restrictions upon
transfer other than as may be permitted under the Credit Agreement, except for the restrictions
described in Section 8.16.



3.8 Intellectual Property. Concurrently with the execution and delivery of this
Agreement by the Pledgors, the Pledgors have delivered to the Agent a schedule of material Patents
and Trademarks, which schedule correctly sets forth all material registered Patents and Trademarks
owned by the Pledgors as of the date hereof. As of date on which the Lien on the Deferred
Interests attaches pursuant hereto, Annexes D, E and F correctly
set forth all registered Copyrights, Patents and Trademarks owned by any Pledgor as of the date
thereof and used or proposed to be used in its business. Except to the extent set forth on
Schedule 3.09(b) to the Credit Agreement, as of the date hereof and as of the date on which the
Lien on such Deferred Interests attaches, each Pledgor owns or possesses the valid right to use all
Copyrights, Patents and Trademarks material to its business and, to the best of such Pledgor’s
knowledge, the use thereof by the Pledgors does not infringe upon the rights of any other Person,
except for any such infringements that, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect. As of the date hereof and as of the date on which the
Lien on the Deferred Interests attaches, all Copyrights, Patents and Trademarks (a) have been duly
registered in, filed in or issued by the United States Patent and Trademark Office or other
corresponding offices of other applicable jurisdictions, where such registration or filing is
commercially reasonable, the subject matter of the Patent or Trademark is not “classified” for
reasons of national security or foreign policy, and registration and filing is permitted by
applicable law or regulation, and (b) have been properly maintained and renewed in accordance with
all applicable provisions of law and administrative regulations in the United States or in each
such other jurisdiction, as applicable, except, in each case, for such Patents, Trademarks or
Copyrights which, as reasonably determined by the Pledgors consistent with prudent and commercially
reasonable business practices (x) are not material to the business of the Pledgors or (y) the
Pledgors have abandoned prior to the date on which the Lien on such Deferred Interests attaches.



3.9 Documents of Title. No material bill of lading, warehouse receipt or other
document or instrument of title is outstanding with respect to any Collateral other than Inventory
in transit in the ordinary course of business to a location set forth on Annex C or to a
Customer of a Pledgor, or to a Fabricator or other nuclear fuel processor.



3.10 Deposit Accounts and Securities Accounts. Annex H correctly sets forth
all Deposit Accounts and Securities Accounts of each Pledgor. Each such Deposit Account (other
than Excluded Accounts) is covered by a deposit account control agreement in favor of the Agent, in
form and substance satisfactory to the Agent. Each Securities Account of any Pledgor is covered by
a securities account control agreement in favor of the Agent, in form and substance satisfactory to
the Agent.



ARTICLE IV




COVENANTS




4.1 Use and Disposition of Collateral. So long as no Event of Default shall have
occurred and be continuing, each Pledgor may, in any lawful manner not inconsistent with the
provisions of this Agreement and the other Financing Documents, use, control and manage the
Collateral in the operation of its businesses, and receive and use the income, revenue and profits
arising therefrom and the Proceeds thereof, in the same manner and with the same effect as if this
Agreement had not been made; provided, however, that no Pledgor will sell or
otherwise dispose of, grant any option with respect to, or grant any Lien with respect to or
otherwise encumber any of the Collateral or any interest therein, except for the security interest
created in favor of the Agent hereunder and except as may be otherwise expressly permitted in
accordance with the terms of this Agreement and the Credit Agreement (including any applicable
provisions therein regarding delivery of proceeds of sale or disposition to the Agent). Nothing
herein shall preclude any Borrower from swapping Inventory for comparable material of equal or
greater value.



4.2 Change of Name, Locations, etc. No Pledgor will (i) change its name, or, if
applicable, the state in which it is registered, (ii) change its chief executive office from the
location thereof listed on Annex C, (iii) except as permitted by Section 4.6, remove any
Collateral (other than goods in transit), or any books, records or other information relating to
Collateral, from the applicable location thereof listed on Annex C, or keep or maintain any
Collateral at a location not listed on Annex C, unless in each case such Pledgor has (A)
given fifteen (15) days’ prior written notice to the Agent of its intention to do so, together with
information regarding any such new location and such other information in connection with such
proposed action as the Agent may reasonably request, and (B) delivered to the Agent fifteen (15)
days prior to any such change or removal of such documents, instruments and financing statements as
may be required under applicable law, all in form and substance reasonably satisfactory to the
Agent, paid all necessary filing and recording fees and taxes, and taken all other actions
reasonably requested by the Agent (including, at the request of the Agent, delivery of opinions of
counsel reasonably satisfactory to the Agent to the effect that all such actions have been taken),
in order to perfect and maintain the Lien upon and security interest in the Collateral provided for
herein in accordance with the provisions of Section 3.2.



4.3 Records; Inspection.



(a) Each Pledgor will keep and maintain at its own cost and expense satisfactory and complete
records of the Accounts and all other Collateral, including, without limitation, records of all
payments received, all credits granted thereon, all merchandise returned and all other
documentation relating thereto, and will furnish to the Agent from time to time such statements,
schedules and reports (including, without limitation, accounts receivable aging schedules) with
regard to the Collateral as the Agent may reasonably request.



(b) In addition to the rights of inspection of the Agent and the Lenders under Section 5.04 of
the Credit Agreement and subject to the provisions of Section 9.12 of the Credit Agreement, each
Pledgor shall, from time to time at such times as may be reasonably requested and upon reasonable
notice, to the extent permitted under Section 5.04 of the Credit Agreement, make available to the
Agent or any Lender for inspection and review at such Pledgor’s offices copies of all invoices and
other documents and information relating to the Collateral (including, without limitation, itemized
schedules of all collections of Accounts, showing the name of each account debtor, the amount of
each payment and such other information as the Agent shall reasonably request). At the request of
the Agent, each Pledgor will legend, in form and manner reasonably satisfactory to the Agent, the
books, records and materials evidencing or relating to the Collateral with an appropriate reference
to the fact that the Collateral has been assigned to the Agent and that the Agent has a security
interest therein. The Agent shall have the right to make test verifications of Accounts in any
reasonable manner and through any reasonable medium, and each Pledgor agrees to furnish all such
reasonable assistance and information as the Agent may require in connection therewith,
provided that, so long as no Event of Default shall have occurred and be continuing, any
such verification shall be conducted either by the Borrower’s independent public accountants in the
name of the Pledgor or in such other manner so as not to disclose the Agent’s identity or interest
in the Collateral.



4.4 Accounts.



(a) Upon the occurrence and continuance of an Event of Default, each Pledgor shall, at the
request of the Agent, take such action as the Agent may deem necessary or advisable (within
applicable laws) to enforce collection of its Accounts. No Pledgor shall, except to the extent
done in the ordinary course of its business consistent with past practices and in accordance with
sound business judgment and provided that no Event of Default shall have occurred and be
continuing, (i) grant any extension of the time for payment of any Account, (ii) compromise or
settle any Account for less than the full amount thereof, (iii) release, in whole or in part, any
person or property liable for the payment of any Account, or (iv) allow any credit or discount on
any Account. In each Borrowing Base Certificate delivered pursuant to Section 5.01(g) of the
Credit Agreement, the Pledgors shall inform the Agent of any material disputes with any account
debtor or obligor and of any claimed offset and counterclaim that may be asserted with respect
thereto, where the Pledgors reasonably believe that the likelihood of payment by such account
debtor is materially impaired, indicating in detail the reason for the dispute, all claims relating
thereto and the amount in controversy.



(b) Except to the extent otherwise permitted under the Credit Agreement or any other Financing
Document, each Pledgor will, at its own cost and expense, (i) arrange for remittances on Accounts
to be made directly to lockboxes designated by the Agent which shall be in the name of the Agent
and subject to control by the Agent or in such other manner as the Agent may direct, and (ii)
promptly deposit, or cause to be deposited, all payments received by such Pledgor on account of
Accounts and the Proceeds of other Collateral or from the sale or other disposition of assets
permitted pursuant to the Credit Agreement, whether in the form of cash, checks, notes, drafts,
bills of exchange, money orders or otherwise, in the Collection Account, in precisely the form
received (but with any endorsements of such Pledgor necessary for deposit or collection), subject
to withdrawal by the Agent only, as hereinafter provided, and until such payments are deposited,
such payments shall be deemed to be held in trust by such Pledgor for and as the Lenders’ property
and shall not be commingled with such Pledgor’s other funds. All remittances and payments that are
deposited in accordance with the foregoing will be applied by the Agent, upon the occurrence and
during the continuation of a Full Cash Dominion Period, in accordance with Section 2.08(b) of the
Credit Agreement; provided, however, that, so long as no Full Cash Dominion Period
is in effect, the Borrowers may require that all remittances and payments that are deposited in
accordance with the foregoing be forwarded to any other account of any Borrower. Except upon the
occurrence and during the continuance of an Event of Default, no payment of a Eurodollar Borrowing
shall be made under this Section on a date other than the last date of the Interest Period for such
Eurodollar Borrowing or the Maturity Date. Upon the occurrence and continuance of an Event of
Default, the Agent may send a notice of assignment and/or notice of the Agent’s security interest
to any and all customers or any third party holding or otherwise concerned with any of the
Collateral, and thereafter the Agent shall have the sole right to collect Accounts and/or take
possession of the Collateral and the books and records relating thereto and to establish Collateral
Accounts as provided for in Section 6.3 hereof.



(c) Pursuant to clause (i) of the definition of “Eligible Receivables” set forth in the Credit
Agreement, Accounts owing from the United States government or any agency or department thereof,
including without limitation, the DOE and the Tennessee Valley Authority, shall, in the Agent’s
Permitted Discretion, not constitute Eligible Receivables unless the Agent shall have received such
documentation from the Pledgors as the Agent shall in its Permitted Discretion upon reasonable
prior notice to the Pledgors require to enable the Agent to make all filings necessary to comply
with the Federal Assignment of Claims Act of 1940, as amended with respect to each contract under
which such Accounts arise (such documentation being the “FACA Documents”). In the event
that the Pledgors have executed and delivered to the Agent any FACA Documents in respect of any
contract and Availability shall fall below $100,000,000 for three (3) consecutive Business Days or
any Event of Default shall occur and be continuing, the Agent shall be entitled to file such FACA
Documents with the applicable Governmental Authorities and, upon such filing, to direct such
Governmental Authorities to make all payments in respect of such Accounts directly to the Agent for
application to the Secured Obligations as provided in this Agreement. The Pledgors agree to
execute and deliver such other documents and take or cause to be taken such other actions as the
Agent may reasonably request in connection with any such filing of FACA Documents pursuant to this
paragraph.



4.5 Instruments. Each Pledgor agrees that if any Collateral shall at any time be
evidenced by a promissory note, tangible Chattel Paper or other Instrument (other than checks or
other Instruments for deposit in the ordinary course of business), the same shall promptly be duly
endorsed to the order of the Agent and delivered to the Agent to be held as Collateral hereunder.



4.6 Inventory. Each Pledgor will, in accordance with sound business practices,
maintain all Eligible Inventory held by it or on its behalf in good saleable or useable condition.
Unless an Event of Default has occurred and is continuing and the Agent has instructed the Pledgors
otherwise, each Pledgor may, in any lawful manner not inconsistent with the provisions of this
Agreement and the other Financing Documents, process, use, ship, deliver and, in the ordinary
course of business or as otherwise permitted under the Credit Agreement, sell, transfer, lease or
otherwise dispose of its Inventory. Without limiting the generality of the foregoing, each Pledgor
agrees that it shall not permit any Inventory to be in the possession of any bailee, warehouseman,
agent or processor (but not including agents engaged for the sole purpose of transporting
Inventory) at any time unless such Pledgor shall have utilized commercially reasonable efforts to
have notified such bailee, warehouseman, agent or processor of the security interest created by
this Agreement and to have obtained, at such Pledgor’s sole cost and expense, a written agreement
by such person to hold such Inventory subject to the security interest created by this Agreement
and the instructions of the Agent and to waive and release any Lien (whether arising by operation
of law or otherwise) such person may have with respect to such Inventory, such agreement to be in
form and substance reasonably satisfactory to the Agent. Each Pledgor further agrees that its
Eligible Inventory will be produced in compliance with the applicable requirements of the Fair
Labor Standards Act, as amended, if such Inventory is produced by Pledgor in the United States.



4.7 Taxes. Each Pledgor will, to the extent required under Section 5.07 of the Credit
Agreement, pay and discharge (i) all taxes, assessments and governmental charges or levies imposed
upon it, upon its income or profits or upon any of its properties, prior to the date on which
penalties would attach thereto, and (ii) all lawful claims for taxes, assessment, governmental
charges or levies that, if unpaid, might become a Lien upon any of the Collateral.



4.8 Insurance.



(a) Each Pledgor will maintain and pay for, or cause to be maintained and paid for, with
financially sound and reputable insurance companies, insurance with respect to its assets,
properties and business, against such hazards and liabilities, of such types and in such amounts,
as is required pursuant to Section 5.02 of the Credit Agreement.



(b) Each Pledgor hereby irrevocably makes, constitutes and appoints the Agent at all times
during the continuance of an Event of Default, its true and lawful attorney (and agent-in-fact) for
the purpose of making, settling and adjusting claims under such policies of insurance, endorsing
its name on any check, draft, instrument or other item or payment for the proceeds of such policies
of insurance and for making all determinations and decisions with respect to such policies of
insurance.



(c) If any Pledgor fails to obtain and maintain any of the policies of insurance required to
be maintained hereunder or to pay any premium in whole or in part, the Agent may, without waiving
or releasing any obligation or Default, at such Pledgor’s expense, but without any obligation to do
so, procure such policies or pay such premiums. All sums so disbursed by the Agent, including
reasonable attorneys’ fees, court costs, expenses and other charges related thereto, shall be
payable by the Pledgors to the Agent on demand and shall be additional Secured Obligations
hereunder, secured by the Collateral.



(d) Each Pledgor will deliver to the Agent, promptly as rendered, true copies of all material
claims and reports made in any reporting forms to insurance companies. Such Pledgor will deliver
to the Agent one or more certificates of insurance evidencing renewal of the insurance coverage
required hereunder (or issuance of a replacement policy from another insurance company meeting the
requirements of this Section 4.8) plus such other evidence of payment of premiums therefor as the
Agent may request. Upon the reasonable request of the Agent from time to time, each Pledgor will
deliver to the Agent evidence that the insurance required to be maintained pursuant to this Section
is in effect.



4.9 Intellectual Property.



(a) Promptly following the Agent’s request from time to time, the Pledgors shall deliver to
the Agent an updated schedule of material Patents and Trademarks, which schedule shall correctly
set forth all material registered Patents and Trademarks owned by the Pledgors; provided,
however that, for so long as Collateral Availability exceeds an amount equal to the greater
of (A) 25% of the aggregate Commitments of all of the Lenders or (B) $75,000,000, such requests
shall be limited to one time each fiscal year; and provided further, that, if an
Event of Default shall have occurred and be continuing, the Agent may request such updated
schedules as often as the Agent may, in its Permitted Discretion, determine to be appropriate. As
of the date on which the Lien on the Deferred Interests attaches, each Pledgor will, at its own
expense, execute and deliver a fully completed Copyright Security Agreement, Patent Security
Agreement or Trademark Security Agreement in the respective forms of Exhibits B,
C and D, as applicable, with regard to any Copyright Collateral, Patent Collateral
or Trademark Collateral (in each case, to the extent registered or filed, subject to the provisions
of Section 3.8 hereof), as the case may be of such Pledgor, described in Annexes D,
E and F hereto. In the event that after such date any Pledgor shall acquire any
registered Copyright Collateral, Patent Collateral or Trademark Collateral or effect any
registration of any such Copyright Collateral, Patent Collateral or Trademark Collateral or file
any application for registration thereof, within the United States, such Pledgor shall promptly
furnish written notice thereof to the Agent together with information sufficient to permit the
Agent, upon its receipt of such notice, to (and each Pledgor hereby authorizes the Agent to) modify
this Agreement, as appropriate, by amending Annex D, E or F hereto or to
add additional exhibits hereto to include any Copyright Collateral, Patent Collateral or Trademark
Collateral (in each case, to the extent registered or filed, subject to the provisions of Section
3.8 hereof) that becomes part of the Collateral under this Agreement, and such Pledgor shall
additionally, at its own expense, execute and deliver, as promptly as possible (but in any event
within ten (10) days) after the date of such notice, with regard to United States Copyrights,
Patents and Trademarks, fully completed Copyright Security Agreements, Patent Security Agreements
or Trademark Security Agreements in the forms of Exhibits B, C and
D, as applicable, together in all instances with any other agreements, instruments and
documents that the Agent may reasonably request from time to time to further effect and confirm the
security interest created by this Agreement in such Copyright Collateral, Patent Collateral and
Trademark Collateral, and each Pledgor hereby appoints the Agent its attorney-in-fact, upon the
occurrence and the continuance of an Event of Default, to execute, deliver and record any and all
such agreements, instruments and documents for the foregoing purposes, all acts of such attorney
being hereby ratified and confirmed and such power, being coupled with an interest, being
irrevocable for so long as this Agreement shall be in effect with respect to such Pledgor. In that
connection, each Pledgor shall also execute and deliver on the date on which the Lien on the
Deferred Interests attaches, such number of Special Powers of Attorney in the form of Annex
I hereto as may be reasonably requested by the Agent.



(b) The Pledgors shall file and prosecute diligently all applications for registration of
Patents, Trademarks or Copyrights now or hereafter pending that would be necessary to the business
of the Pledgors to which any such applications pertain, and do all acts (or refrain from doing all
acts), in any such instance, reasonably necessary to preserve and maintain all material rights in
Patents, Trademarks or Copyrights, unless such Patents, Trademarks or Copyrights are not material
to the business of the Pledgors, as reasonably determined by the Pledgors consistent with prudent
and commercially reasonable business practices.



(c) From and after the date on which the Lien on the Deferred Interests attaches, each Pledgor
shall notify the Agent promptly if it knows or has reason to know that any material Patent
Collateral, Trademark Collateral or Copyright Collateral used in the conduct of its business may
become abandoned or dedicated to the public, or of any adverse determination or development
(including the institution of, or any such determination or development in, any proceeding in the
U.S. Patent and Trademark Office, U.S. Copyright Office or any court) regarding such Pledgor’s
ownership of any material Patent Collateral, Trademark Collateral or Copyright Collateral, its
right to register the same, or to keep and maintain the same.



(d) From and after the date on which the Lien on the Deferred Interests attaches, in the event
that any Collateral consisting of a material Patent Collateral, Trademark Collateral or Copyright
Collateral used in the conduct of any Pledgor’s business is believed infringed, misappropriated or
diluted by a third party, such Pledgor shall notify the Agent promptly after it learns thereof and
shall, if consistent with the exercise of reasonable business judgment and applicable laws,
regulations and agreements to which the applicable Pledgor is a party, promptly sue for
infringement, misappropriation or dilution and to recover any and all damages for such
infringement, misappropriation or dilution, and take such other actions as are appropriate under
the circumstances to protect such Collateral.



(e) From and after the date on which the Lien on the Deferred Interests attaches, upon the
occurrence and during the continuance of any Event of Default, each Pledgor shall use its
commercially reasonable efforts to obtain all requisite consents or approvals from the licensor of
each material License included within the Copyright Collateral, Patent Collateral or Trademark
Collateral to effect the assignment of all of such Pledgor’s right, title and interest thereunder
to the Agent or its designee.



4.10 Delivery of Collateral. All certificates or instruments representing or
evidencing any material Account, Equity Interest or other Collateral delivered to the Agent
pursuant hereto, shall be in form suitable for transfer by delivery and shall be delivered together
with undated stock powers duly executed in blank, appropriate endorsements or other necessary
instruments of registration, transfer or assignment, duly executed and in form and substance
satisfactory to the Agent, and in each case such other instruments or documents as the Agent may
reasonably request.



4.11 Deposit and Collection Procedures. Each Pledgor agrees that, upon the creation
of a new Deposit Account (other than an Excluded Account or any account which is part of the DOE
Collateral) not held with the Agent or any new Securities Account, it will immediately enter into a
control agreement in favor of the Agent for such Deposit Account or Securities Account, as
applicable, in form and substance satisfactory to the Agent. Subject to the foregoing exceptions,
no Proceeds of Accounts will be deposited in or at any time transferred to such a Deposit Account
other than such a Deposit Account covered by a control agreement in favor of the Agent in form and
substance reasonably satisfactory to the Agent; provided that in no event shall any
Proceeds of Accounts be deposited in or at any time transferred to any account which is part of the
DOE Collateral. Nothing contained in this Section 4.11 shall prohibit the Pledgors from making any
pledges or deposits permitted by the Credit Agreement.



4.12 Protection of Security Interest. Each Pledgor agrees that it will use
commercially reasonable efforts, at its own cost and expense, to take any and all actions necessary
to warrant and defend the right, title and interest of the Agent and Secured Parties in and to the
Collateral against the claims and demands of all other persons.



4.13 Control of Investment Property and Electronic Chattel Paper. If any Investment
Property (whether now owned or hereafter acquired) is included in the Collateral, each applicable
Pledgor will notify the Agent thereof and will promptly take and cause to be taken all actions
required under Articles 8 and 9 of the Uniform Commercial Code and any other applicable law to
enable the agent to acquire “control” (within the meaning of such term under Section 8-106 (or its
successor provision) of the Uniform Commercial Code) of such Investment Property and as may be
otherwise necessary or deemed appropriate by the Agent to perfect the security interest of the
Agent therein. If any Account of any Pledgor would constitute “electronic chattel paper” as
defined under the Uniform Commercial Code, each Pledgor will promptly notify the Agent and will
take such other steps as may be necessary or deemed appropriate by the Agent to give the Agent
“control” over such electronic chattel paper (within the meaning of Section 9-105 of the Uniform
Commercial Code).



4.14 Supplements to Schedules and Annexes. The Credit Parties shall, from time to
time (including, without limitation, in connection with any reaffirmation by the Pledgors of the
representations and warranties made by any Pledgor hereunder or under any Financing Document), and
upon the reasonable request of the Agent, amend or supplement in writing and deliver to the Agent
revisions of and supplements to the Annexes and schedules hereto to the extent necessary to
disclose new or changed facts or circumstances arising after the Effective Date, which, if existing
or occurring on such date, would have been required to be set forth or described in such Annex or
schedule hereto; provided that (i) in connection with any amendment or supplement to
Annex A, the Credit Parties shall comply with Section 5.1(b), (ii) in connection with any
amendment or supplement to Annex B, the Credit Parties shall provide the Agent at least
fifteen (15) days’ advance notice of any such amendment or supplement (or such shorter period as
the Agent may approve), shall comply with Section 4.2 and shall take any other action reasonably
requested by Agent in connection therewith to maintain the Lien of Agent on the Collateral after
giving effect to such amendment or supplement, (iii) in connection with any amendment or supplement
to Annex H, the Credit Parties shall provide the Agent at least fifteen (15) days’ advance
notice of any such amendment or supplement (or such shorter period as the Agent may approve), shall
comply with Sections 3.10 and 4.11 and shall take any other action reasonably requested by Agent in
connection therewith to maintain the Lien of Agent on the Collateral after giving effect to such
amendment or supplement, (iv) in connection with any amendment or supplement to Annex C,
the Credit Parties shall comply with Section 4.2, (v) in connection with any amendment or
supplement to Annexes D, E or F, the Credit Parties shall comply
with Section 4.9(a), and (vi) no such amendment or supplement to any such Annex shall constitute a
waiver of any Default or Event of Default in existence on or prior to the date of such amendment or
supplement. Any reference to an Annex or schedule in this Agreement shall refer to such Annex as
amended or supplemented from time to time in accordance with this Section 4.14.



ARTICLE V




CERTAIN PROVISIONS RELATING TO EQUITY INTERESTS




5.1 Ownership; After-Acquired Equity Interests.



(a) Except as otherwise permitted under Section 6.03(c) of the Credit Agreement or in
connection with any Restructuring Event, each Pledgor will cause the Equity Interests pledged by it
hereunder (including without limitation, all Equity Interests constituting Deferred Interests which
would become Collateral if a Deferred Interests Triggering Event were to occur) to constitute at
all times 100% of the capital stock or other Equity Interests in each issuer held by such Pledgor
thereof, such that the issuer thereof shall be a wholly owned subsidiary of such Pledgor,
provided that (i) in no event shall the Parent cease to own, directly or indirectly through
one or more Guarantor Pledgors, 100% of the Equity Interests in Enrichment and (ii) if, after
giving effect to any transaction permitted by Sections 6.03(c) of the Credit Agreement or in
connection with any Restructuring Event, any Equity Interests of any issuer pledged hereunder are
held by any Subsidiary which is not a Pledgor, the Parent shall cause such Subsidiary to execute
and deliver a Pledgor Guarantee and a Pledgor Addendum pursuant to which such Subsidiary shall
become a Pledgor hereunder and grant a first priority Lien in favor of the Agent on the Collateral
of such Subsidiary, including without limitation, all such Equity Interests (subject, in the case
of any Equity Interests constituting Deferred Interests, to Section 2.3). Unless the Agent shall
have given its prior written consent, no Pledgor will cause or permit any such issuer to issue or
sell any new capital stock, any warrants, options or rights to acquire the same, or other Equity
Interests of any nature to any person other than such Pledgor, or cause, permit or consent to the
admission of any other person as a stockholder, partner or member of any such issuer.



(b) If any Pledgor shall, at any time and from time to time (or, in the case of any Equity
Interests constituting Deferred Interests, if any Pledgor shall, at any time and from time to time
from and after the occurrence of a Deferred Interests Triggering Event), acquire any additional
capital stock or other Equity Interests in any person of the types described in the definition of
the term “Equity Interests” (including, without limitation, pursuant to any transaction
permitted by Section 6.03(c) of the Credit Agreement or in connection with any Restructuring
Event), the same shall be automatically deemed to be Equity Interests, and shall be deemed to be
pledged to the Agent pursuant to Section 2.1 or, in the case of Equity Interests constituting
Deferred Interests, pursuant to Section 2.3, and such Pledgor will forthwith pledge and deposit the
same with the Agent and deliver to the Agent any certificates or instruments therefor, together
with the endorsement of such Pledgor (in the case of any promissory notes or other Instruments),
undated stock powers (in the case of Equity Interests evidenced by certificates) or other necessary
instruments of transfer or assignment, duly executed in blank and in form and substance
satisfactory to the Agent, together with such other certificates and instruments as the Agent may
reasonably request (including Uniform Commercial Code financing statements or appropriate
amendments thereto), and will promptly thereafter deliver to the Agent a fully completed and duly
executed amendment to this Agreement in the form of Exhibit A (each, a “Pledge
Amendment”) in respect thereof. Each Pledgor hereby authorizes the Agent to attach each such
Pledge Amendment to this Agreement, and agrees that all such Collateral listed on any Pledge
Amendment shall for all purposes be deemed Collateral hereunder and shall be subject to the
provisions hereof, provided that the failure of any Pledgor to execute and deliver any
Pledge Amendment with respect to any such additional Collateral as required hereinabove shall not
impair the security interest of the Agent in such Collateral or otherwise adversely affect the
rights and remedies of the Agent hereunder with respect thereto.



(c) If any Equity Interests (whether now owned or hereafter acquired) included in the
Collateral are “uncertificated securities” within the meaning of the Uniform Commercial Code or are
otherwise not evidenced by any certificate or instrument, each applicable Pledgor will promptly
notify the Agent thereof and will promptly take and cause to be taken, and will (if the issuer of
such uncertificated securities is a person other than a direct or indirect subsidiary of the
Parent) use its best efforts to cause the issuer to take, all actions required under Articles 8 and
9 of the Uniform Commercial Code and any other applicable law, to enable the Agent to acquire
“control” (within the meaning of such term under Section 8-106 (or its successor provision) of the
Uniform Commercial Code) of such uncertificated securities and as may be otherwise necessary or
deemed appropriate by the Agent to perfect the security interest of the Agent therein.



5.2 Voting Rights. So long as no Event of Default shall have occurred and be
continuing, each Pledgor shall be entitled to exercise all voting and other consensual rights
pertaining to its Equity Interests (subject to its obligations under Section 5.1) which have become
Collateral, and for that purpose the Agent will execute and deliver or cause to be executed and
delivered to each applicable Pledgor all such proxies and other instruments as such Pledgor may
reasonably request in writing to enable the Pledgor to exercise such voting and other consensual
rights; provided, however, that no Pledgor will cast any vote, give any consent,
waiver or ratification, or take or fail to take any action, in any manner that would, or could
reasonably be expected to, violate or be inconsistent with any of the terms of this Agreement, the
Credit Agreement or any other Financing Document, or have the effect of impairing the position or
interests of the Agent or any other Secured Party in such Collateral.



5.3 Dividends and Other Distributions. So long as no Full Cash Dominion Period shall
be in effect, and except as provided otherwise herein or in the Credit Agreement, all interest,
income, dividends, distributions and other amounts payable in cash in respect of the Equity
Interests which have become Collateral shall be paid to and retained by the Pledgors;
provided, however, that all such interest, income, dividends, distributions and
other amounts shall, at all times after the occurrence and during the continuance of a Full Cash
Dominion Period, be paid to the Agent and retained by it as part of the Collateral (except to the
extent applied upon receipt to the repayment of the Secured Obligations). The Agent shall also be
entitled at all times (whether or not during the continuance of a Full Cash Dominion Period) to
receive directly, and to retain as part of the Collateral, (i) all interest, income, dividends,
distributions or other amounts paid or payable in cash or other property in respect of any Equity
Interests which have become Collateral in connection with the dissolution, liquidation,
recapitalization or reclassification of the capital of the applicable issuer to the extent
representing an extraordinary, liquidating or other distribution in return of capital, (ii) all
additional Equity Interests or other securities or property (other than cash) paid or payable or
distributed or distributable in respect of any Equity Interests which have become Collateral in
connection with any noncash dividend, distribution, return of capital, spin-off, stock split,
split-up, reclassification, combination of shares or interests or similar rearrangement, and (iii)
without affecting any restrictions against such actions contained in the Credit Agreement, all
additional Equity Interests or other securities or property (including cash) paid or payable or
distributed or distributable in respect of any Equity Interests which have become Collateral in
connection with any consolidation, merger, exchange of securities, liquidation or other
reorganization. All interest, income, dividends, distributions or other amounts that are received
by any Pledgor in violation of the provisions of this Section shall be received in trust for the
benefit of the Agent, shall be segregated from other property or funds of such Pledgor and shall be
forthwith delivered to the Agent as Collateral in the same form as so received (with any necessary
endorsements).



ARTICLE VI




REMEDIES




6.1 Remedies. If an Event of Default shall have occurred and be continuing, the Agent
shall be entitled to exercise in respect of the Collateral all of its rights, powers and remedies
provided for herein or otherwise available to it under any other Financing Document, by law, in
equity or otherwise, including all rights and remedies of a secured party under the Uniform
Commercial Code, and shall be entitled in particular, but without limitation of the foregoing, to
exercise the following rights, which each Pledgor agrees to be commercially reasonable:



(a) To notify any or all account debtors or obligors under any Accounts or other Collateral of
the security interest in favor of the Agent created hereby and to direct all such persons to make
payments of all amounts due thereon or thereunder directly to the Agent or to an account designated
by the Agent; and in such instance and from and after such notice, all amounts and Proceeds
(including wire transfers, checks and other instruments) received by any Pledgor in respect of any
Accounts or other Collateral shall be received in trust for the benefit of the Agent hereunder,
shall be segregated from the other funds of such Pledgor and shall be forthwith deposited into such
account or paid over or delivered to the Agent in the same form as so received (with any necessary
endorsements or assignments), to be held as Collateral and applied to the Secured Obligations as
provided herein;



(b) To take possession of, receive, endorse, assign and deliver, in its own name or in the
name of any Pledgor, all checks, notes, drafts and other instruments relating to any Collateral,
including receiving, opening and properly disposing of all mail addressed to any Pledgor concerning
Accounts and other Collateral and to notify the appropriate postal authority to change the mailing
or delivery address of such mail; to verify with account debtors or other contract parties the
validity, amount or any other matter relating to any Accounts or other Collateral, in its own name
or in the name of any Pledgor; to accelerate any indebtedness or other obligation constituting
Collateral that may be accelerated in accordance with its terms; to take or bring all actions and
suits deemed necessary or appropriate to effect collections and to enforce payment of any Accounts
or other Collateral; to settle, compromise or release in whole or in part any amounts owing on
Accounts or other Collateral; and to extend the time of payment of any and all Accounts or other
amounts owing under any Collateral and to make allowances and adjustments with respect thereto, all
in the same manner and to the same extent as any Pledgor might have done;



(c) To originate instructions to any or all depository institutions with which any Deposit
Accounts are maintained and any or all securities intermediaries with which any Securities Accounts
are maintained, including without limitation, instructions to terminate the Pledgors’ access to
such Deposit Accounts or Securities Accounts and instructions to remit and transfer all monies,
securities and other property on deposit in such Deposit Accounts or Securities Accounts or
deposited or received for deposit thereafter to the Agent, for deposit in a Collateral Account or
such other accounts as may be designated by the Agent, for application to the Secured Obligations
as provided herein;



(d) Subject to applicable law and regulation, to transfer to or register in its name or the
name of any of its agents or nominees all or any part of the Collateral, without notice to any
Pledgor and with or without disclosing that such Collateral is subject to the security interest
created hereunder;



(e) Subject to applicable law and regulation, to require any Pledgor to, and each Pledgor
hereby agrees that it will at its expense and upon request of the Agent forthwith, assemble all or
any part of the Collateral as directed by the Agent and to the extent permitted by applicable law
make it available to the Agent at a place designated by the Agent and each Pledgor further agrees
that the Agent shall have no obligation to clean-up or otherwise prepare the Collateral for sale;



(f) To the extent permitted by applicable law, to enter and remain upon the premises of any
Pledgor and take possession of all or any part of the Collateral, with or without judicial process;
to use the materials, services, books and records of any Pledgor for the purpose of liquidating or
collecting the Collateral, whether by foreclosure, auction or otherwise; and to remove the same to
the premises of the Agent or any designated agent for such time as the Agent may desire, in order
to effectively collect or liquidate the Collateral;



(g) Subject to applicable law and regulation, to exercise, but only at the request of Required
Lenders, to the extent permitted by applicable law, (i) all voting, consensual and other rights and
powers pertaining to the Equity Interests (whether or not transferred into the name of the Agent),
at any meeting of shareholders, partners, members or otherwise, and (ii) any and all rights of
conversion, exchange, subscription and any other rights, privileges or options pertaining to the
Equity Interests as if it were the absolute owner thereof (including, without limitation, the right
to exchange at its discretion any and all of the Equity Interests upon the merger, consolidation,
reorganization, reclassification, combination of shares or interests, similar rearrangement or
other similar fundamental change in the structure of the applicable issuer, or upon the exercise by
any Pledgor or the Agent of any right, privilege or option pertaining to such Equity Interests),
and in connection therewith, the right to deposit and deliver any and all of the Equity Interests
with any committee, depositary, transfer agent, registrar or other designated agency upon such
terms and conditions as the Agent may determine, and give all consents, waivers and ratifications
in respect of the Equity Interests, all without liability except to account for any property
actually received by it, but the Agent shall have no duty to exercise any such right, privilege or
option or give any such consent, waiver or ratification and shall not be responsible for any
failure to do so or delay in so doing; and for the foregoing purposes each Pledgor will promptly
execute and deliver or cause to be executed and delivered to the Agent, upon request, all such
proxies and other instruments as the Agent may reasonably request to enable the Agent to exercise
such rights and powers; AND IN FURTHERANCE OF THE FOREGOING AND WITHOUT LIMITATION THEREOF, EACH
PLEDGOR HEREBY IRREVOCABLY CONSTITUTES AND APPOINTS THE AGENT AS THE TRUE AND LAWFUL PROXY AND
ATTORNEY-IN-FACT OF SUCH PLEDGOR, WITH FULL POWER OF SUBSTITUTION IN THE PREMISES, UPON THE
OCCURRENCE AND DURING THE CONTINUANCE OF AN EVENT OF DEFAULT, TO EXERCISE ALL SUCH VOTING,
CONSENSUAL AND OTHER RIGHTS AND POWERS TO WHICH ANY HOLDER OF ANY EQUITY INTERESTS WOULD BE
ENTITLED BY VIRTUE OF HOLDING THE SAME, WHICH PROXY AND POWER OF ATTORNEY, BEING COUPLED WITH AN
INTEREST, IS IRREVOCABLE AND SHALL BE EFFECTIVE FOR SO LONG AS THIS AGREEMENT SHALL BE IN EFFECT.
Each of Enrichment and NAC International agrees that, notwithstanding anything to the contrary set
forth in Article V, Section 6 of its bylaws, it will recognize the security interest and the rights
and remedies of the Agent under this Agreement, including without limitation, the right of the
Agent to exercise the remedies set forth in Sections 6.1(d) and (h) and in this Section 6.1(g) upon
the occurrence and during the continuance of an Event of Default; and



(h) Subject to applicable law and regulation, to sell, resell, assign and deliver, in its sole
discretion, all or any of the Collateral, in one or more parcels, on any securities exchange on
which any Equity Interests may be listed, at public or private sale, at any of the Agent’s offices
or elsewhere, for cash, upon credit or for future delivery, at such time or times and at such price
or prices and upon such other terms as the Agent may deem satisfactory. If any of the Collateral
is sold by the Agent upon credit or for future delivery, the Agent shall not be liable for the
failure of the purchaser to purchase or pay for the same and, in the event of any such failure, the
Agent may resell such Collateral. In no event shall any Pledgor be credited with any part of the
Proceeds of sale of any Collateral until and to the extent cash payment in respect thereof has
actually been received by the Agent. Each purchaser at any such sale shall hold the property sold
absolutely, free from any claim or right of whatsoever kind, including any equity or right of
redemption of any Pledgor, and each Pledgor hereby expressly waives, to the fullest extent
permitted under applicable law, all rights of redemption, stay or appraisal, and all rights to
require the Agent to marshal any assets in favor of such Pledgor or any other party or against or
in payment of any or all of the Secured Obligations, that it has or may have under any rule of law
or statute now existing or hereafter adopted. No demand, presentment, protest, advertisement or
notice of any kind (except any notice required by law, as referred to below), all of which are
hereby expressly waived by each Pledgor, shall be required in connection with any sale or other
disposition of any part of the Collateral. If any notice of a proposed sale or other disposition
of any part of the Collateral shall be required under applicable law, the Agent shall give the
applicable Pledgor at least ten (10) days’ prior notice of the time and place of any public sale
and of the time after which any private sale or other disposition is to be made, which notice each
Pledgor agrees is commercially reasonable. The Agent shall not be obligated to make any sale of
Collateral if it shall determine not to do so, regardless of the fact that notice of sale may have
been given. The Agent may, without notice or publication, adjourn any public or private sale or
cause the same to be adjourned from time to time by announcement at the time and place fixed for
sale, and such sale may, without further notice, be made at the time and place to which the same
was so adjourned. Upon each public sale and, to the extent permitted by applicable law, upon each
private sale, the Agent may purchase all or any of the Collateral being sold, free from any equity,
right of redemption or other claim or demand, and may make payment therefor by endorsement and
application (without recourse) of the Secured Obligations in lieu of cash as a credit on account of
the purchase price for such Collateral. The Agent shall, to the extent required by applicable
laws, comply with any applicable state or federal law requirements in connection with the sale or
other disposition of the Collateral and each Pledgor agrees that such compliance is commercially
reasonable. The Agent may sell or otherwise dispose of the Collateral without giving any
warranties, specifically disclaiming any warranties of title or the like and each Pledgor agrees
that such disclaimer is commercially reasonable.



Notwithstanding anything to the contrary set forth herein, in no event shall, by virtue of this
Agreement, any person or entity that is a “foreign person” or a “contravening person,” in each
case, as defined below, (i) have any beneficial ownership interest in, or control of, any Equity
Interests in Enrichment (or its successor) or (ii) exercise any rights and remedies hereunder with
respect to the Equity Interests in Enrichment (or its successor) (x) that is inconsistent with or
in violation of the regulations, rules or restrictions of any Governmental Authority that exercises
regulatory power over Enrichment, its business, operations or assets or (y) that could jeopardize
Enrichment’s continued operations, including, without limitation, pursuant to licenses issued by
any Governmental Authority. For purposes of this paragraph, “foreign person” shall mean (i) an
individual who is not a citizen of the United States of America; (ii) a partnership in which any
general partner is a foreign person or the partner or partners having a majority interest in
partnership profits are foreign persons; (iii) a foreign government or representative thereof; (iv)
a corporation, partnership, trust, company, association or other entity organized or incorporated
under the laws of a jurisdiction outside of the United States and (v) a corporation, partnership,
trust, company, association or other entity that is controlled, directly or indirectly, by any one
or more of the foregoing. For purposes of this paragraph, “contravening person” shall mean (i) any
person or entity incorporated, organized or having its principal place of business outside of the
United States that is in the business of (x) enriching uranium for use by nuclear reactors or (y)
creating a fissile product capable of use as a fuel source for nuclear reactors in lieu of enriched
uranium or (ii) any Affiliate of any person or entity described in clause (i) of this definition;
or (iii) any person or entity having a significant commercial relationship with any person or
entity described in clauses (i) or (ii) of this definition.



6.2 Application of Proceeds.



(a) All Proceeds collected by the Agent upon any sale, other disposition of or realization
upon any of the Collateral, together with all other moneys received by the Agent hereunder
following the occurrence and during the continuance of an Event of Default shall be applied in
accordance with Section 2.16(b) of the Credit Agreement



(b) For purposes of applying amounts in accordance with this Section, the Agent shall be
entitled to rely upon any Secured Party that has entered into a Swap Obligation with any Pledgor or
provided any cash management services to any Pledgor for a determination (which such Secured Party
agrees to provide or cause to be provided upon request of the Agent) of the outstanding Swap
Obligations or Banking Services Obligations owed to such Secured Party. Unless it has actual
knowledge (including by way of written notice from any such Secured Party) to the contrary, the
Agent, in acting hereunder, shall be entitled to assume that no Swap Obligations or Banking
Services Obligations or Secured Obligations in respect thereof are in existence between any Secured
Party and any Pledgor.



(c) Each Pledgor shall remain liable to the extent of any deficiency between the amount of all
Proceeds realized upon sale, other disposition or collection of the Collateral, and monies held as
Collateral pursuant to this Agreement and the aggregate amount of Secured Obligations. Upon any
sale of any Collateral hereunder by the Agent (whether by virtue of the power of sale herein
granted, pursuant to judicial proceeding, or otherwise), the receipt by the Agent or the officer
making the 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 Agent or such officer or be answerable in any way for the
misapplication thereof.



6.3 Collateral Accounts. Upon the occurrence and during the continuance of an Event
of Default, the Agent shall have the right to cause to be established and maintained, at its
principal office or such other location or locations as it may establish from time to time in its
discretion, one or more accounts (collectively, “Collateral Accounts”) for the collection
of cash Proceeds of the Collateral. Such Proceeds, when deposited, shall continue to constitute
Collateral for the Secured Obligations and shall not constitute payment thereof until applied as
herein provided. The Agent shall have sole dominion and control over all funds deposited in any
Collateral Account, and such funds may be withdrawn therefrom only by the Agent. Upon the
occurrence and during the continuance of an Event of Default, the Agent shall have the right to
(and, if directed by the Required Lenders pursuant to the Credit Agreement, shall) apply amounts
held in the Collateral Accounts in payment of the Secured Obligations in the manner provided for in
Section 6.2. Collateral Accounts shall be promptly liquidated and all monies credited thereto
shall be paid over to the Pledgor(s) once the Secured Obligations have been paid or reimbursed in
full or cash collateralized. Thereafter, cash proceeds of Collateral need not be paid into
Collateral Accounts unless and until another Loan or Letter of Credit is requested.



6.4 Grant of License. To the extent permitted by applicable law and solely for the
purpose of enabling the Secured Parties to exercise rights and remedies under Article VI, and at
such time as the Secured Parties shall be lawfully entitled to exercise such rights and remedies,
each Pledgor hereby grants to the Agent, to the extent it has the right to do so, an irrevocable,
non-exclusive license (exercisable without payment of royalty or other compensation to any
Pledgor), subject, in the case of Trademarks, to sufficient rights to quality control and
inspection in favor of each Pledgor to avoid the risk of invalidation of such Trademarks, to use,
license or sublicense any Patent Collateral, Trademark Collateral or Copyright Collateral now owned
or hereafter acquired by such Pledgor, wherever the same may be located throughout the world, for
such term or terms, on such conditions and in such manner as the Agent shall determine, whether
general, special or otherwise, and whether on an exclusive or nonexclusive basis, and including in
such license reasonable access to all media in which any of the licensed items may be recorded or
stored and to all computer software and programs used for the compilation or printout thereof. The
use of such license or sublicense by the Agent shall be exercised, at the option of the Agent, and
only upon the occurrence and during the continuation of an Event of Default; provided that
any license, sublicense or other transaction entered into by the Agent in accordance herewith shall
be binding upon each applicable Pledgor notwithstanding any subsequent cure of an Event of Default.



6.5 Private Sales.



(a) Each Pledgor recognizes that, by reason of certain prohibitions contained in the
Securities Act and applicable state securities laws as in effect from time to time, the Agent may
be compelled, with respect to any sale of all or any part of the Equity Interests conducted without
registration or qualification under the Securities Act and such state securities laws, to limit
purchasers to any one or more persons who will represent and agree, among other things, to acquire
such Equity Interests for their own account, for investment and not with a view to the distribution
or resale thereof. Each Pledgor acknowledges that any such private sales may be made in such
manner and under such circumstances as the Agent may deem necessary or advisable in its sole and
absolute discretion, including at prices and on terms less favorable than those obtainable through
a public sale without such restrictions (including, without limitation, a public offering made
pursuant to a registration statement under the Securities Act), and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have been made in a
commercially reasonable manner and agrees that the Agent shall have no obligation to conduct any
public sales and no obligation to delay the sale of any Equity Interests for the period of time
necessary to permit its registration for public sale under the Securities Act and applicable state
securities laws, and shall not have any responsibility or liability as a result of its election so
not to conduct any such public sales or delay the sale of any Equity Interests, notwithstanding the
possibility that a substantially higher price might be realized if the sale were deferred until
after such registration. Each Pledgor hereby waives any claims against the Agent or any other
Secured Party arising by reason of the fact that the price at which any Equity Interests may have
been sold at any private sale was less than the price that might have been obtained at a public
sale or was less than the aggregate amount of the Secured Obligations, even if the Agent accepts
the first offer received and does not offer such Equity Interests to more than one offeree.



(b) Each Pledgor agrees that a breach of any of the covenants contained in this Section will
cause irreparable injury to the Agent and the other Secured Parties, that the Agent and the other
Secured Parties have no adequate remedy at law in respect of such breach and, as a consequence,
that each and every covenant contained in this Section shall be specifically enforceable against
the Pledgors.



6.6 Waivers. Each Pledgor, to the greatest extent not prohibited by applicable law,
hereby (i) agrees that it will not invoke, claim or assert the benefit of any rule of law or
statute now or hereafter in effect (including, without limitation, any right to prior notice or
judicial hearing in connection with the Agent’s possession, custody or disposition of any
Collateral or any appraisal, valuation, stay, extension, moratorium or redemption law), or take or
omit to take any other action, that would or could reasonably be expected to have the effect of
delaying, impeding or preventing the exercise of any rights and remedies in respect of the
Collateral, the absolute sale of any of the Collateral or the possession thereof by any purchaser
at any sale thereof, and waives the benefit of all such laws and further agrees that it will not
hinder, delay or impede the execution of any power granted hereunder to the Agent, but that it will
permit the execution of every such power as though no such laws were in effect, (ii) waives all
rights that it has or may have under any rule of law or statute now existing or hereafter adopted
to require the Agent to marshal any Collateral or other assets in favor of such Pledgor or any
other party or against or in payment of any or all of the Secured Obligations, and (iii) waives all
rights that it has or may have under any rule of law or statute now existing or hereafter adopted
to demand, presentment, protest, advertisement or notice of any kind (except notices expressly
provided for herein or in the other Financing Documents) or to require the Agent to pursue any
third party for any of the Secured Obligations.



ARTICLE VII




THE AGENT




7.1 The Agent; Standard of Care. The Agent will hold all items of the Collateral at
any time received under this Agreement in accordance with the provisions hereof and the other
Financing Documents. The obligations of the Agent as holder of the Collateral and interests
therein and with respect to the disposition thereof, and otherwise under this Agreement and the
other Financing Documents, are only those expressly set forth in this Agreement and the other
Financing Documents. The Agent, to the extent required under the Credit Agreement, shall act
hereunder at the direction, or with the consent, of the Required Lenders on the terms and
conditions set forth in the Credit Agreement. The powers conferred on the Agent hereunder are
solely to protect its interest, on behalf of the Secured Parties, in the Collateral, and shall not
impose any duty upon it to exercise any such powers. Except for treatment of the Collateral in its
possession in the same manner as that which the Agent, in its individual capacity, accords its own
property of a similar nature for its own account, and the accounting for moneys actually received
by it hereunder, the Agent shall have no duty as to any Collateral or as to the taking of any
necessary steps to preserve rights against prior parties or any other rights pertaining to the
Collateral. Neither the Agent nor any other Secured Party shall be liable to any Pledgor (i) for
any loss or damage sustained by such Pledgor, or (ii) for any loss, damage, depreciation or other
diminution in the value of any of the Collateral that may occur as a result of or in connection
with or that is in any way related to any exercise by the Agent or any other Secured Party of any
right or remedy under this Agreement, any failure to demand, collect or realize upon any of the
Collateral or any delay in doing so, or any other act or failure to act on the part of the Agent or
any other Secured Party, except to the extent that the same is caused by its own gross negligence
or willful misconduct.



7.2 Further Assurances; Attorney-in-Fact.



(a) Each Pledgor hereby authorizes the Agent to sign (to the extent the Pledgor’s signature is
required thereon) and file financing statements and amendments thereto relating to all or any part
of the Collateral without the signature of such Pledgor (including, without limitation, making any
notice filings with state tax or revenue authorities required to be made by account creditors in
order to enforce any Accounts in such state); provided that, promptly following the filing
thereof, the Agent shall provide the Pledgors with a copy of any initial financing statement filed
by the Agent or any amendment to any initial financing statement which changes the collateral
description set forth therein; provided, further, that the Agent’s failure to do so shall
not impair or limit the validity or effectiveness of any such initial financing statement or
amendment. The Pledgor further agrees to execute and deliver to the Agent such additional
conveyances, assignments, agreements and instruments as the Agent may reasonably require under
applicable law to perfect, establish, confirm and maintain the security interest and Lien provided
for herein, to carry out the purposes of this Agreement or to further assure and confirm unto the
Agent its rights, powers and remedies hereunder.



(b) Each Pledgor hereby irrevocably appoints the Agent its lawful attorney-in-fact, with full
authority in the place and stead of such Pledgor and in the name of such Pledgor, the Agent or
otherwise, and with full power of substitution in the premises (which power of attorney, being
coupled with an interest, is irrevocable for so long as this Agreement shall be in effect), from
time to time in the Agent’s discretion after the occurrence and during the continuance of an Event
of Default (except for the actions described in clause (vii) below which may be taken by the Agent
without regard to whether an Event of Default has occurred) to take any action and to execute any
instruments that the Agent may deem necessary or advisable to accomplish the purpose of this
Agreement, including, without limitation:




(i) to ask, demand, collect, sue for, recover, compound, receive and give
acquittance and receipts for moneys due and to become due under or in respect of any
of the Collateral;




(ii) to receive, endorse and collect any checks, drafts, instruments, chattel
paper and other orders for the payment of money made payable to such Pledgor
representing any interest, income, dividend, distribution or other amount payable in
respect of any of the Collateral and to give full discharge for the same;




(iii) to obtain, maintain and adjust any property or casualty insurance
required to be maintained by such Pledgor under Section 4.8 and direct the payment
of proceeds thereof to the Agent;




(iv) to pay or discharge taxes, Liens or other encumbrances levied or placed on
or threatened against the Collateral, the legality or validity thereof and the
amounts necessary to discharge the same to be determined by the Agent in its sole
discretion, any such payments made by the Agent to become Secured Obligations of the
Pledgors to the Agent, due and payable immediately and without demand;




(v) to file any claims or take any action or institute any proceedings that the
Agent may deem necessary or advisable for the collection of any of the Collateral or
otherwise to enforce the rights of the Agent with respect to any of the Collateral;




(vi) to use, sell, assign, transfer, pledge, make any agreement with respect to
or otherwise deal with any and all of the Collateral as fully and completely as
though the Agent were the absolute owner of the Collateral for all purposes, and to
do from time to time, at the Agent’s option and the Pledgors’ expense, all other
acts and things deemed necessary by the Agent to protect, preserve or realize upon
the Collateral and to more completely carry out the purposes of this Agreement; and




(vii) to sign the name of such Pledgor on (to the extent the Pledgor’s
signature is required thereon) and to file any financing statement, continuation
statement, notice or other similar document that, in the Agent’s Permitted
Discretion, should be made or filed in order to perfect or continue to perfect the
security interest granted under this Agreement;



(c) If any Pledgor fails to perform any covenant or agreement contained in this Agreement
after written request to do so by the Agent (provided that no such request shall be
necessary at any time after the occurrence and during the continuance of an Event of Default), the
Agent may itself perform, or cause the performance of, such covenant or agreement and may take any
other action that it deems necessary and appropriate for the maintenance and preservation of the
Collateral or its security interest therein, and the reasonable expenses so incurred in connection
therewith shall be payable by the Pledgors under Section 8.1.



ARTICLE VIII




MISCELLANEOUS




8.1 Indemnity and Expenses. The Pledgors agree jointly and severally:



(a) to indemnify and hold harmless the Agent, each other Secured Party and each of their
respective directors, officers, employees, agents and affiliates from and against any and all
claims, damages, demands, losses, obligations, judgments and liabilities (including, without
limitation, reasonable attorneys’ fees and expenses) in any way arising out of or in connection
with this Agreement, except to the extent the same shall arise as a result of the gross negligence
or willful misconduct of the party seeking to be indemnified; and



(b) to pay and reimburse the Agent upon demand for all reasonable costs and expenses
(including, without limitation, reasonable attorneys’ fees and expenses) that the Agent may incur
in connection with (i) the custody, use or preservation of, or the sale of, collection from or
other realization upon, any of the Collateral, including the reasonable expenses of retaking,
holding, preparing for sale or lease, selling or otherwise disposing of or realizing on the
Collateral, (ii) the exercise or enforcement of any rights or remedies granted hereunder
(including, without limitation, under Article VI), under any of the other Financing Documents or
otherwise available to it (whether at law, in equity or otherwise), or (iii) the failure by any
Pledgor to perform or observe any of the provisions hereof. The provisions of this Section shall
survive the execution and delivery of this Agreement, the repayment of any of the Secured
Obligations, the termination or expiration of all Letters of Credit under the Credit Agreement, the
termination of the Commitments under the Credit Agreement and the termination of this Agreement or
any other Financing Document.



8.2 No Waiver. The rights and remedies of the Secured Parties expressly set forth in
this Agreement and the other Financing Documents are cumulative and in addition, to, and not
exclusive of, all other rights and remedies available at law, in equity or otherwise. No failure
or delay on the part of any Secured Party in exercising any right, power or privilege shall operate
as a waiver thereof, nor shall any single or partial exercise of any such right, power or privilege
preclude any other or further exercise thereof or the exercise of any other right, power or
privilege or be construed to be a waiver of any Default or Event of Default. No course of dealing
between the Pledgors and the Secured Parties or their agents or employees shall be effective to
amend, modify or discharge any provision of this Agreement or any other Financing Document or to
constitute a waiver of any Default or Event of Default. No notice to or demand upon any Pledgor in
any case shall entitle such Pledgor or any other Pledgor to any other or further notice or demand
in similar or other circumstances or constitute a waiver of the right of any Secured Party to
exercise any right or remedy or take any other or further action in any circumstances without
notice or demand.



8.3 Pledgors’ Obligations Absolute. Until such time as this Agreement terminates
pursuant to Section 8.6, each Pledgor agrees that its obligations hereunder, and the security
interest granted to and all rights, remedies and powers of the Agent hereunder, are irrevocable,
absolute and unconditional and shall not be discharged, limited or otherwise affected (unless
agreed to by the parties hereto) by reason of any of the following, whether or not such Pledgor has
knowledge thereof:




(i) any change in the time, manner or place of payment of, or in any other term
of, any Secured Obligations, or any amendment, modification or supplement to,
restatement of, or consent to any rescission or waiver of or departure from, any
provisions of the Credit Agreement, any Pledgor Guarantee, any other Financing
Document or any agreement or instrument delivered pursuant to any of the foregoing;




(ii) the invalidity or unenforceability of any Secured Obligations or any
provisions of the Credit Agreement, any Pledgor Guarantee, any other Financing
Document or any agreement or instrument delivered pursuant to any of the foregoing;




(iii) the addition or release of Pledgors hereunder or the taking, acceptance
or release of any Secured Obligations or additional Collateral or other security
therefor;




(iv) any sale, exchange, release, substitution, compromise, nonperfection or
other action or inaction in respect of any Collateral or other direct or indirect
security for any Secured Obligations, or any discharge, modification, settlement,
compromise or other action or inaction in respect of any Secured Obligations;




(v) any agreement not to pursue or enforce or any failure to pursue or enforce
(whether voluntarily or involuntarily as a result of operation of law, court order
or otherwise) any right or remedy in respect of any Secured Obligations or any
Collateral or other security therefor, or any failure to create, protect, perfect,
secure, insure, continue or maintain any Liens in any such Collateral or other
security;




(vi) the exercise of any right or remedy available under the Financing
Documents, at law, in equity or otherwise in respect of any Collateral or other
security for any Secured Obligations, in any order and by any manner thereby
permitted, including, without limitation, foreclosure on any such Collateral or
other security by any manner of sale thereby permitted, whether or not every aspect
of such sale is commercially reasonable;




(vii) any bankruptcy, reorganization, arrangement, liquidation, insolvency,
dissolution, termination, reorganization or like change in the corporate structure
or existence of the Borrower, any other Pledgor or any other person directly or
indirectly liable for any Secured Obligations;




(viii) any manner of application of any payments by or amounts received or
collected from any person, by whomsoever paid and howsoever realized, whether in
reduction of any Secured Obligations or any other obligations of the Borrowers or
any other person directly or indirectly liable for any Secured Obligations,
regardless of what Secured Obligations may remain unpaid after any such application;
or




(ix) any other circumstance that might otherwise constitute a legal or
equitable discharge of, or a defense, set-off or counterclaim available to, the
Borrowers, any Pledgor or a surety or guarantor generally, other than the occurrence
of all of the following: (x) the payment in full of the Secured Obligations, (y)
the termination or expiration of all Letters of Credit under the Credit Agreement
and (z) the termination of the Commitments under the Credit Agreement (the events in
clauses (x), (y) and (z) above, collectively, the “Termination
Requirements”).



8.4 Enforcement. By its acceptance of the benefits of this Agreement, each Secured
Party agrees that this Agreement may be enforced only by the Agent, acting upon the instructions or
with the consent of the Lenders to the extent provided for in the Credit Agreement, and that no
Secured Party shall have any right individually to enforce or seek to enforce this Agreement or to
realize upon any Collateral or other security given to secure the payment and performance of the
Secured Obligations.



8.5 Amendments, Waivers, etc. No amendment, modification, waiver, discharge or
termination of, or consent to any departure by any Pledgor from, any provision of this Agreement,
shall be effective unless in a writing executed and delivered in accordance with Section 9.02 of
the Credit Agreement, and then the same shall be effective only in the specific instance and for
the specific purpose for which given.



8.6 Continuing Security Interest; Term; Successors and Assigns; Assignment; Termination
and Release; Survival. This Agreement shall create a continuing security interest in the
Collateral and shall secure the payment and performance of all of the Secured Obligations as the
same may arise and be outstanding at any time and from time to time from and after the date hereof,
and shall (i) remain in full force and effect until the occurrence of the Termination Requirements,
(ii) be binding upon and enforceable against each Pledgor and its successors and assigns
(provided, however, that no Pledgor may sell, assign or transfer any of its rights,
interests, duties or obligations hereunder without the prior written consent of the Lenders) and
(iii) inure to the benefit of and, subject to Section 8.4, be enforceable by each Secured Party and
its successors and assigns. Upon any sale, lease, transfer or other disposition by any Pledgor of
any Collateral (including, without limitation, any ACP Property) in a transaction expressly
permitted hereunder or under or pursuant to the Credit Agreement or any other applicable Financing
Document, or any amendment or waiver hereunder or thereunder, the Lien and security interest
created by this Agreement in and upon such Collateral shall be automatically released, upon any
Pledgor ceasing to be a Guarantor pursuant to a transaction so permitted, the Lien and security
interest created by this Agreement in any Collateral of such Pledgor shall be automatically
released and upon the satisfaction of all of the Termination Requirements, this Agreement and the
Lien and security interest created hereby shall terminate; and in connection with any such release
or termination, the Agent, at the request and expense of the applicable Pledgor, will execute and
deliver to such Pledgor such documents and instruments evidencing such release or termination as
such Pledgor may reasonably request and will assign, transfer and deliver to such Pledgor, without
recourse and without representation or warranty, such of the Collateral as may then be in the
possession of the Agent (or, in the case of any partial release of Collateral, such of the
Collateral so being released as may be in its possession). All representations, warranties,
covenants and agreements herein shall survive the execution and delivery of this Agreement and any
Pledge Amendment or Pledgor Addendum.



8.7 Additional Pledgors. Each Pledgor recognizes that the provisions of the Credit
Agreement require persons that become Material Subsidiaries of the Parent (other than a Foreign
Subsidiary), and that are not already parties hereto, to execute and deliver a Pledgor Addendum,
whereupon each such Person shall become a Pledgor hereunder with the same force and effect as if
originally a Pledgor hereunder on the date hereof, and agrees that its obligations hereunder shall
not be discharged, limited or otherwise affected by reason of the same, or by reason of the Agent’s
actions in effecting the same or in releasing any Pledgor hereunder, in each case without the
necessity of giving notice to or obtaining the consent of such Pledgor or any other Pledgor.



8.8 Notices. All notices and other communications provided for hereunder shall be
given to the parties in the manner and subject to the other notice provisions set forth in (i) in
the case of the Borrowers or the Agent, the Credit Agreement and (ii) in the case of any other
Pledgor, its Pledgor Guarantee.



8.9 Applicable Law. THIS AGREEMENT, IN ACCORDANCE WITH SECTION 5-1401 OF THE GENERAL
OBLIGATION LAW OF THE STATE OF NEW YORK, SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE
LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ANY CONFLICTS OF LAWS PRINCIPLES THEREOF THAT WOULD
CALL FOR THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION, BUT IN ANY EVENT GIVING EFFECT TO
FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.



8.10 Severability. To the extent any provision of this Agreement is prohibited by or
invalid under the applicable law of any jurisdiction, such provision shall be ineffective only to
the extent of such prohibition or invalidity and only in such jurisdiction, without prohibiting or
invalidating such provision in any other jurisdiction or the remaining provisions of this Agreement
in any jurisdiction.

Agreement have been inserted for convenience only and shall not in any way affect the meaning or

singular include the plural and words in the plural include the singular.



8.12 Counterparts. This Agreement may be executed in counterparts (and by different
parties hereto on different counterparts), each of which shall constitute an original but all of
which when taken together shall constitute but one contract, and shall become effective when copies
hereof which, when taken together, bear the signatures of each of the parties hereto shall be
delivered to the Agent. Delivery of an executed counterpart of a signature page to this Agreement
by telecopier shall be effective as delivery of a manually executed signature page hereto.



8.13 Submission to Jurisdiction. Any legal action or proceeding with respect to this
Agreement may be brought in the courts of the State of New York or of the United States of America
for the Southern District of New York, and, by execution and delivery of this Agreement, each
Pledgor hereby submits for itself and in respect of its property, generally and unconditionally, to
the jurisdiction of the aforesaid courts, waives any objection, including, without limitation, any
objection to the laying of venue or based on the grounds of forum non conveniens, which such

such action or proceeding by the mailing of copies thereof by registered or certified mail, postage
prepaid, to each such person, as the case may be, as provided for in Section 8.8. The Agent may

proceed against any Pledgor in any other jurisdiction.

CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO
ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION.
