SECTION 2.06. Voting Rights; Dividends and Interest. (a) Unless and until an Event of Default shall have occurred and be continuing and the Collateral Agent shall have notified the U.S. Borrower that the rights of the Grantors under this Section 2.06 are being suspended:

(i) Each Grantor shall be entitled to exercise any and all voting and/or other consensual rights and powers inuring to an owner of Pledged Securities or any part thereof for any purpose consistent with the terms of this Agreement, the Credit Agreement and the other Loan Documents; provided that such rights and powers shall not be exercised in any manner that could materially and adversely affect the rights inuring to a holder of any Pledged Securities or the rights and remedies of any of the Collateral Agent or the other Secured Parties under this Agreement, the Credit Agreement, any other Loan Document or the ability of the Secured Parties to exercise the same.

(ii) The Collateral Agent shall execute and deliver to each Grantor, or cause to be executed and delivered to such Grantor, all such proxies, powers of attorney and other instruments as such Grantor may reasonably request for the purpose of enabling such Grantor to exercise the voting and/or consensual rights and powers it is entitled to exercise pursuant to subparagraph (i) above.

7

(b) Upon the occurrence and during the continuance of an Event of Default, after the Collateral Agent shall have notified the U.S. Borrower of the suspension of the rights of the Grantors under paragraph (a)(iii) of this Section 2.06, then all rights of any Grantor to dividends, interest, principal or other distributions that such Grantor is authorized to receive pursuant to paragraph (a)(iii) of this Section 2.06 shall cease, and all such rights shall thereupon become vested in the Collateral Agent, which shall have the sole and exclusive right and authority to receive and retain such dividends, interest, principal or other distributions. All dividends, interest, principal or other distributions received by any Grantor contrary to the provisions of this Section 2.06 shall be held in trust for the benefit of the Collateral Agent, shall be segregated from other property or funds of such Grantor and shall be forthwith delivered to the Collateral Agent upon demand in the same form as so received (with any necessary endorsement reasonably requested by the Collateral Agent).

After all Events of Default have been cured or waived, each Grantor shall have the exclusive right to exercise the voting and/or consensual rights and powers that such Grantor would otherwise be entitled to exercise pursuant to the terms of paragraph (a)(i) above.

(d) Any notice given by the Collateral Agent to the U.S. Borrower suspending the rights of the Grantors under paragraph (a) of this Section 2.06 (i) shall be given in writing, (ii) may be given with respect to one or more of the Grantors at the same or different times and (iii) may suspend the rights of the Grantors under paragraph (a)(i) or paragraph (a)(iii) in part without suspending all such rights (as specified by the Collateral Agent in its sole and absolute discretion) and without waiving or otherwise affecting the Collateral Agent’s rights to give additional notices from time to time suspending other rights so long as an Event of Default has occurred and is continuing.

(a) Each Grantor has good and valid rights in and title to the Article 9 Collateral with respect to which it has purported to grant a Security Interest hereunder and has full power and authority to grant to the Collateral Agent the Security Interest in such Article 9 Collateral pursuant hereto and to execute, deliver and perform its obligations in accordance with the terms of this Agreement, without the consent or approval of any other Person other than any consent or approval that has been obtained.

(b) The Perfection Certificate has been duly prepared, completed and executed and the information set forth therein, including the exact legal name of each Grantor, is correct and complete in all material repects as of the Closing Date. The Uniform Commercial Code financing statements (including fixture filings, as applicable) or other appropriate filings, recordings or registrations prepared by the Collateral Agent based upon the information provided to the Collateral Agent in the Perfection Certificate for filing in each governmental, municipal or other office specified in the Perfection Certificate, are all the filings, recordings and registrations that are necessary to establish a legal, valid and perfected security interest in favor of the Collateral Agent (for the benefit of the Secured Parties) in respect of all Article 9 Collateral in which the Security Interest may be perfected by filing, recording or registration in the United States (or any political subdivision thereof) and its territories and possessions, and no further or subsequent filing, refiling, recording, rerecording, registration or reregistration is necessary in any such jurisdiction, except as provided under applicable law with respect to the filing of continuation statements.

(c) The Security Interest constitutes (i) a legal and valid security interest in all the Article 9 Collateral securing the payment and performance of the Secured Obligations and (ii) subject to the filings described in Section 3.02(b), a perfected security interest in all Article 9 Collateral in which a security interest may be perfected by filing, recording or registering a financing statement or analogous document in the United States (or any political subdivision thereof) and its territories and possessions pursuant to the Uniform Commercial Code. The Security Interest is and shall be prior to any other Lien on any of the Article 9 Collateral, other than Liens expressly permitted pursuant to Section 7.01 of the Credit Agreement.

(d) The Article 9 Collateral is owned by the Grantors free and clear of any Lien, except for Liens expressly permitted pursuant to Section 7.01 of the Credit Agreement. None of the Grantors has filed or consented to the filing of (i) any financing statement or analogous document under the Uniform Commercial Code or any other applicable laws covering any Article 9 Collateral or (ii) any assignment in which any Grantor assigns any Article 9 Collateral or any security agreement or similar instrument covering any Article 9 Collateral with any

11

foreign governmental, municipal or other office, which financing statement or analogous document, assignment, security agreement or similar instrument is still in effect, except, in each case, for Liens expressly permitted pursuant to Section 7.01 of the Credit Agreement.

SECTION 3.03. Covenants. (a) The U.S. Borrower agrees promptly to notify the Collateral Agent in writing of any change (i) in legal name of any Grantor, (ii) in the identity or type of organization or corporate structure of any Grantor, or (iii) in the jurisdiction of organization of any Grantor.

(b) Each Grantor shall, at its own expense, take any and all commercially reasonable actions necessary to defend title to the Article 9 Collateral against all Persons and to defend the Security Interest of the Collateral Agent in the Article 9 Collateral and the priority thereof against any Lien not expressly permitted pursuant to Section 7.01 of the Credit Agreement.

(c) The U.S. Borrower agrees, on its own behalf and on behalf of each other Grantor, at its own expense, to execute, acknowledge, deliver and cause to be duly filed all such further instruments and documents and take all such actions as the Collateral Agent may from time to time reasonably request to better assure, preserve, protect and perfect the Security Interest and the rights and remedies created hereby, including the payment of any fees and taxes required in connection with the execution and delivery of this Agreement, the granting of the Security Interest and the filing of any financing statements (including fixture filings) or other documents in connection herewith or therewith.

(d) At its option, the Collateral Agent may discharge past due taxes, assessments, charges, fees, Liens, security interests or other encumbrances at any time levied or placed on the Article 9 Collateral and not permitted pursuant to Section 7.01 of the Credit Agreement, and may pay for the maintenance and preservation of the Article 9 Collateral to the extent any Grantor fails to do so as required by the Credit Agreement or this Agreement and within a reasonable period of time after the Collateral Agent has requested that it do so, and each Grantor jointly and severally agrees to reimburse the Collateral Agent within 10 days after demand for any payment made or any reasonable expense incurred by the Collateral Agent pursuant to the foregoing authorization. Nothing in this paragraph shall be interpreted as excusing any Grantor from the performance of, or imposing any obligation on the Collateral Agent or any Secured Party to cure or perform, any covenants or other promises of any Grantor with respect to taxes, assessments, charges, fees, Liens, security interests or other encumbrances and maintenance as set forth herein or in the other Loan Documents.

(e) Each Grantor (rather than the Collateral Agent or any Secured Party) shall remain liable (as between itself and any relevant counterparty) to observe and perform all the conditions and obligations to be observed and performed by it under each contract, agreement or instrument relating to the Article 9 Collateral, all in accordance with the terms and conditions thereof, and each Grantor jointly and severally agrees to indemnify and hold harmless the Collateral Agent and the Secured Parties from and against any and all liability for such performance.

12

SECTION 3.04. Other Actions. In order to further insure the attachment, perfection and priority of, and the ability of the Collateral Agent to enforce, the Security Interest, each Grantor agrees, in each case at such Grantor’s own expense, to take the following actions with respect to the following Article 9 Collateral:

(a) Instruments. If any Grantor shall at any time hold or acquire any Instruments constituting Collateral and evidencing an amount in excess of $10,000,000, such Grantor shall forthwith endorse, assign and deliver the same to the Collateral Agent for the benefit of the applicable Secured Parties, accompanied by such instruments of transfer or assignment duly executed in blank as the Collateral Agent may from time to time reasonably request.

(b) Investment Property. Except to the extent otherwise provided in Article II, if any Grantor shall at any time hold or acquire any certificated securities, such Grantor shall forthwith endorse, assign and deliver the same to the Collateral Agent for the benefit of the applicable Secured Parties, accompanied by such instruments of transfer or assignment duly executed in blank as the Collateral Agent may from time to time reasonably request. If any securities now or hereafter acquired by any Grantor are uncertificated and are issued to such Grantor or its nominee directly by the issuer thereof, upon the Collateral Agent’s request and following the occurrence of an Event of Default such Grantor shall promptly notify the Collateral Agent thereof and, at the Collateral Agent’s reasonable request, pursuant to an agreement in form and substance reasonably satisfactory to the Collateral Agent, either (i) cause the issuer to agree to comply with instructions from the Collateral Agent as to such securities, without further consent of any Grantor or such nominee, or (ii) arrange for the Collateral Agent to become the registered owner of the securities. If any securities, whether certificated or uncertificated, or other investment property are held by any Grantor or its nominee through a securities intermediary or commodity intermediary, upon the Collateral Agent’s request following the occurrence of an Event of Default, such Grantor shall immediately notify the Collateral Agent thereof and at the Collateral Agent’s request and option, pursuant to an agreement in form and substance reasonably satisfactory to the Collateral Agent shall either (i) cause such securities intermediary or (as the case may be) commodity intermediary to agree to comply with entitlement orders or other instructions from the Collateral Agent to such securities intermediary as to such security entitlements, or (as the case may be) to apply any value distributed on account of any commodity contract as directed by the Collateral Agent to such commodity intermediary, in each case without further consent of any Grantor or such nominee, or (ii) in the case of financial assets or other Investment Property held through a securities intermediary, arrange for the Collateral Agent to become the entitlement holder with respect to such Investment Property, with the Grantor being permitted, only with the consent of the Collateral Agent, to exercise rights to withdraw or otherwise deal with such Investment Property. The Collateral Agent agrees with

13

each of the Grantors that the Collateral Agent shall not give any such entitlement orders or instructions or directions to any such issuer, securities intermediary or commodity intermediary, and shall not withhold its consent to the exercise of any withdrawal or dealing rights by any Grantor, unless an Event of Default has occurred and is continuing. The provisions of this paragraph shall not apply to any financial assets credited to a securities account for which the Collateral Agent is the securities intermediary.

(c) Commercial Tort Claims. If any Grantor shall at any time hold or acquire a Commercial Tort Claim in an amount reasonably estimated by such Grantor to exceed $10,000,000 and for which a complaint in a court of competent jurisdiction has been filed (or with respect to which such Grantor’s affirmative intent to file such a complaint or to settle the claim absent court proceeding has been documented in writing to the obligor of such claim), the Grantor shall promptly notify the Collateral Agent thereof in a writing signed by such Grantor including a summary description of such claim and grant to the Collateral Agent, for the benefit of the Secured Parties, in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to the Collateral Agent.

(d) Letter-of-Credit Rights. If any Grantor is at any time a beneficiary under a Letter of Credit now or hereafter issued, such Grantor shall promptly notify the Collateral Agent thereof and such Grantor shall, at the request of the Collateral Agent, pursuant to an agreement in form and substance reasonably satisfactory to the Collateral Agent, either (i) arrange for the issuer and any confirmer of such Letter of Credit to consent to an assignment to the Collateral Agent of the proceeds of any drawing under the Letter of Credit or (ii) arrange for the Collateral Agent to become the transferee beneficiary of such Letter of Credit, with the Collateral Agent agreeing, in each case, that, during the continuance of an Event of Default, upon the Collateral Agent’s election, the proceeds of any drawing under the Letter of Credit are to be applied as provided in the Credit Agreement. The actions in the preceding sentence shall not be required to the extent that the amount of any such Letter of Credit does not exceed $10,000,000.

ARTICLE IV

Remedies

SECTION 4.01. Remedies Upon Default. Upon the occurrence and during the continuance of an Event of Default, it is agreed that the Collateral Agent shall have the right to exercise any and all rights afforded to a secured party with respect to the Secured Obligations under the Uniform Commercial Code or other applicable law and also may (i) require each Grantor to, and each Grantor agrees that it will at its expense and upon request of the Collateral Agent forthwith, assemble all or part of the Collateral as directed by the Collateral Agent and make it available to the Collateral Agent at a place and time to be designated by the Collateral Agent that is reasonably convenient to

14

both parties; (ii) occupy any premises owned or, to the extent lawful and permitted, leased by any of the Grantors where the Collateral or any part thereof is assembled or located for a reasonable period in order to effectuate its rights and remedies hereunder or under law, without obligation to such Grantor in respect of such occupation; provided that the Collateral Agent shall provide the applicable Grantor with notice thereof prior to or promptly after such occupancy; (iii) exercise any and all rights and remedies of any of the Grantors under or in connection with the Collateral, or otherwise in respect of the Collateral; provided that the Collateral Agent shall provide the applicable Grantor with notice thereof prior to or promptly after such exercise; and (iv) subject to the mandatory requirements of applicable law and the notice requirements described below, sell or otherwise dispose of all or any part of the Collateral securing the Secured Obligations at a public or private sale or at any broker’s board or on any securities exchange, for cash, upon credit or for future delivery as the Collateral Agent shall deem appropriate. The Collateral Agent shall be authorized at any such sale of securities (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and upon consummation of any such sale the Collateral Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each such purchaser at any sale of Collateral shall hold the property sold absolutely, free from any claim or right on the part of any Grantor, and each Grantor hereby waives (to the extent permitted by law) all rights of redemption, stay and appraisal which such Grantor now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted.

The Collateral Agent shall give the applicable Grantors 10 days’ written notice (which each Grantor agrees is reasonable notice within the meaning of Section 9-611 of the New York UCC or its equivalent in other jurisdictions) of the Collateral Agent’s intention to make any sale of Collateral. Such notice, in the case of a public sale, shall state the time and place for such sale and, in the case of a sale at a broker’s board or on a securities exchange, shall state the board or exchange at which such sale is to be made and the day on which the Collateral, or portion thereof, will first be offered for sale at such board or exchange. Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as the Collateral Agent may fix and state in the notice (if any) of such sale. At any such sale, the Collateral, or portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as the Collateral Agent may (in its sole and absolute discretion) determine. The Collateral Agent shall not be obligated to make any sale of any Collateral if it shall determine not to do so, regardless of the fact that notice of sale of such Collateral shall have been given. The Collateral 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. In case any sale of all or any part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by the Collateral Agent until the sale price is paid by the purchaser or purchasers thereof, but the Collateral Agent shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may be sold

15

again upon like notice. At any public (or, to the extent permitted by law, private) sale made pursuant to this Agreement, any Secured Party may bid for or purchase, free (to the extent permitted by law) from any right of redemption, stay, valuation or appraisal on the part of any Grantor (all said rights being also hereby waived and released to the extent permitted by law), the Collateral or any part thereof offered for sale and may make payment on account thereof by using any claim then due and payable to such Secured Party from any Grantor as a credit against the purchase price, and such Secured Party may, upon compliance with the terms of sale, hold, retain and dispose of such property without further accountability to any Grantor therefor. For purposes hereof, a written agreement to purchase the Collateral or any portion thereof shall be treated as a sale thereof; the Collateral Agent shall be free to carry out such sale pursuant to such agreement and no Grantor shall be entitled to the return of the Collateral or any portion thereof subject thereto, notwithstanding the fact that after the Collateral Agent shall have entered into such an agreement all Events of Default shall have been remedied and the Secured Obligations paid in full. As an alternative to exercising the power of sale herein conferred upon it, the Collateral Agent may proceed by a suit or suits at law or in equity to foreclose this Agreement and to sell the Collateral or any portion thereof pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver. Any sale pursuant to the provisions of this Section 4.01 shall be deemed to conform to the commercially reasonable standards as provided in Section 9-610(b) of the New York UCC or its equivalent in other jurisdictions.

Each Grantor irrevocably makes, constitutes and appoints the Collateral Agent (and all officers, employees or agents designated by the Collateral Agent) as such Grantor’s true and lawful agent (and attorney-in-fact) during the continuance of an Event of Default and after notice to the U.S. Borrower of its intent to exercise such rights, for the purpose of (i) making, settling and adjusting claims in respect of Article 9 Collateral under policies of insurance, endorsing the name of such Grantor on any check, draft, instrument or other item of payment for the proceeds of such policies if insurance, (ii) making all determinations and decisions with respect thereto and (iii) obtaining or maintaining the policies of insurance required by Section 6.07 of the Credit Agreement or to pay any premium in whole or in part relating thereto. All sums disbursed by the Collateral Agent in connection with this paragraph, including reasonable attorneys’ fees, court costs, expenses and other charges relating thereto, shall be payable, within 10 days of demand, by the Grantors to the Collateral Agent and shall be additional Secured Obligations secured hereby.

SECTION 4.02. Application of Proceeds. (a) The Collateral Agent shall apply the proceeds of any collection or sale of Collateral, including any Collateral consisting of cash, in the order provided for in Section 8.04 of the Credit Agreement.

The Collateral Agent shall have absolute discretion as to the time of application of any such proceeds, moneys or balances in accordance with this Agreement. Upon any sale of Collateral by the Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Collateral Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or

16

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 Collateral Agent or such officer or be answerable in any way for the misapplication thereof.

(b) In making the determination and allocations required by this Section 4.02, the Collateral Agent may conclusively rely upon information supplied by the Administrative Agent as to the amounts of unpaid principal and interest and other amounts outstanding with respect to the Secured Obligations, and the Collateral Agent shall have no liability to any of the Secured Parties for actions taken in reliance on such information, provided that nothing in this sentence shall prevent any Grantor from contesting any amounts claimed by any Secured Party in any information so supplied. All distributions made by the Collateral Agent pursuant to this Section 4.02 shall be (subject to any decree of any court of competent jurisdiction) final (absent manifest error), and the Collateral Agent shall have no duty to inquire as to the application by the Administrative Agent of any amounts distributed to it.

ARTICLE V

Indemnity, Subrogation and Subordination

SECTION 5.01. Indemnity. In addition to all such rights of indemnity and subrogation as the Grantors may have under applicable law (but subject to Section 5.03), the U.S. Borrower agrees that, in the event any assets of any Grantor shall be sold pursuant to this Agreement or any other Collateral Document to satisfy in whole or in part an obligation owed to any Secured Party, the U.S. Borrower shall indemnify such Grantor in an amount equal to the greater of the book value or the fair market value of the assets so sold.

SECTION 5.02. Contribution and Subrogation. Each Grantor other than the U.S. Borrower (a “Contributing Party”) agrees (subject to Section 5.03) that, in the event assets of any other Grantor other than the U.S. Borrower shall be sold pursuant to any Collateral Document to satisfy any Secured Obligation owed to any Secured Party and such other Grantor (the “Claiming Party”) shall not have been fully indemnified by the U.S. Borrower as provided in Section 5.01, the Contributing Party shall indemnify the Claiming Party in an amount equal to the greater of the book value or the fair market value of such assets, in each case multiplied by a fraction of which the numerator shall be the net worth of the Contributing Party on the date hereof and the denominator shall be the aggregate net worth of all the Contributing Parties together with the net worth of the Claiming Party on the date hereof (or, in the case of any Grantor becoming a party hereto pursuant to Section 6.14, the date of the Security Agreement Supplement hereto executed and delivered by such Grantor). Any Contributing Party making any payment to a Claiming Party pursuant to this Section 5.02 shall be subrogated to the rights of such Claiming Party to the extent of such payment.

17

SECTION 5.03. Subordination. (a) Notwithstanding any provision of this Agreement to the contrary, all rights of the Grantors under Sections 5.01 and 5.02 and all other rights of indemnity, contribution or subrogation under applicable law or otherwise shall be fully subordinated to the indefeasible payment in full in cash of the Secured Obligations. No failure on the part of any Borrower or any Grantor to make the payments required by Sections 5.01 and 5.02 (or any other payments required under applicable law or otherwise) shall in any respect limit the obligations and liabilities of any Grantor with respect to its obligations hereunder, and each Grantor shall remain liable for the full amount of the obligations of such Grantor hereunder.

(b) Each Grantor hereby agrees that upon the occurrence and during the continuance of an Event of Default and after notice from the Collateral Agent all Indebtedness owed to it by any Subsidiary shall be fully subordinated to the indefeasible payment in full in cash of the Secured Obligations.

ARTICLE VI

Miscellaneous

SECTION 6.01. Notices. All communications and notices hereunder shall (except as otherwise expressly permitted herein) be in writing and given as provided in Section 10.02 of the Credit Agreement. All communications and notices hereunder to any Grantor other than the U.S. Borrower shall be given to it in care of the U.S. Borrower as provided in Section 10.02 of the Credit Agreement.

SECTION 6.02. Waivers; Amendment. (a) No failure or delay by any Secured Party in exercising any right or power hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Secured Parties hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section 6.02, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether any Secured Party may have had notice or knowledge of such Default at the time. No notice or demand on any Loan Party in any case shall entitle any Loan Party to any other or further notice or demand in similar or other circumstances.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Collateral Agent and the Loan Party or Loan Parties with respect to which such waiver, amendment or modification is to apply, subject to any consent required in accordance with Section 10.01 of the Credit Agreement.

18

SECTION 6.03. Collateral Agent’s Fees and Expenses; Indemnification. (a) The parties hereto agree that the Collateral Agent shall be entitled to reimbursement of its expenses incurred hereunder as provided in Section 10.04 of the Credit Agreement.

(b) Without limitation of its indemnification obligations under the other Loan Documents, the U.S. Borrower agrees to indemnify the Collateral Agent and the other Indemnitees (as defined in Section 10.05 of the Credit Agreement) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of, the execution, delivery or performance of this Agreement or any claim, litigation, investigation or proceeding relating to any of the foregoing or any agreement or instrument contemplated hereby, or to the Collateral, whether or not any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or of any Affiliate, director, officer, employee, counsel, agent or attorney-in-fact of such Indemnitee.

(c) Any such amounts payable as provided hereunder shall be additional Secured Obligations secured hereby and by the other Collateral Documents. The provisions of this Section 6.03 shall remain operative and in full force and effect regardless of the termination of this Agreement or any other Loan Document, the consummation of the transactions contemplated hereby, the repayment of any of the Secured Obligations, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan Document, or any investigation made by or on behalf of the Collateral Agent or any other Secured Party. All amounts due under this Section 6.03 shall be payable within 10 days of written demand therefor.

SECTION 6.04. Successors and Assigns. Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to include the permitted successors and assigns of such party; and all covenants, promises and agreements by or on behalf of any Grantor or the Collateral Agent that are contained in this Agreement shall bind and inure to the benefit of their respective successors and assigns.

SECTION 6.05. Survival of Agreement. All covenants, agreements, representations and warranties made by the Loan Parties in the Loan Documents and in the certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the Secured Parties and shall survive the execution and delivery of the Loan Documents and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any Secured Party or on its behalf and notwithstanding that any Secured Party may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended under the Credit Agreement, and shall continue in full force and effect as long as the principal of or any accrued

19

interest on any Loan or any fee or any other amount payable under any Loan Document is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated.

SECTION 6.06. Counterparts; Effectiveness; Several Agreement. This Agreement may be executed in counterparts, each of which shall constitute an original but all of which when taken together shall constitute a single contract. Delivery of an executed signature page to this Agreement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Agreement. This Agreement shall become effective as to any Loan Party when a counterpart hereof executed on behalf of such Loan Party shall have been delivered to the Collateral Agent and a counterpart hereof shall have been executed on behalf of the Collateral Agent, and thereafter shall be binding upon such Loan Party and the Collateral Agent and their respective permitted successors and assigns, and shall inure to the benefit of such Loan Party, the Collateral Agent and the other Secured Parties and their respective successors and assigns, except that no Loan Party shall have the right to assign or transfer its rights or obligations hereunder or any interest herein or in the Collateral (and any such assignment or transfer shall be void) except as expressly contemplated by this Agreement or the Credit Agreement. This Agreement shall be construed as a separate agreement with respect to each Loan Party and may be amended, modified, supplemented, waived or released with respect to any Loan Party without the approval of any other Loan Party and without affecting the obligations of any other Loan Party hereunder.

SECTION 6.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 6.08. Right of Set-Off. In addition to any rights and remedies of the Secured Parties provided by Law and the Credit Agreement, upon the occurrence and during the continuance of any Event of Default, each Secured Party and its Affiliates is authorized at any time and from time to time, without prior notice to the U.S. Borrower or any other Loan Party, any such notice being waived by the U.S. Borrower and each Loan Party to the fullest extent permitted by applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other Indebtedness at any time owing by, such Secured Party and its Affiliates to or for the credit or the account of the respective Loan Parties against any and all obligations owing to such Secured Party and its Affiliates hereunder, now or hereafter existing, irrespective of whether or not such Secured Party or Affiliate shall have made demand under this Agreement and although such obligations may be contingent or unmatured or denominated in a currency different from that of the applicable deposit or Indebtedness. Each Secured Party agrees promptly to notify the U.S. Borrower and the Collateral Agent

20

after any such set off and application made by such Secured Party; provided, that the failure to give such notice shall not affect the validity of such setoff and application. The rights of each Secured Party under this Section 6.08 are in addition to other rights and remedies (including other rights of setoff) that such Secured Party may have.

SECTION 6.09. Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the law of the State of New York.

(b) Each of the Loan Parties hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York City and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any other Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that any Secured Party may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against any Grantor or its properties in the courts of any jurisdiction.

(c) Each of the Loan Parties hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (b) of this Section 6.09. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 6.01. Nothing in this Agreement or any other Loan Document will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 6.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT

21

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 6.10.

SECTION 6.11. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement.

SECTION 6.12. Security Interest Absolute. Except as otherwise set forth herein regarding the obligations of the Third Party Pledgor, all rights of the Collateral Agent hereunder, the Security Interest, the grant of a security interest in the Pledged Collateral and all obligations of each Grantor hereunder shall be absolute and unconditional irrespective of (a) any lack of validity or enforceability of the Credit Agreement, any other Loan Document, any agreement with respect to any of the Secured Obligations or any other agreement or instrument relating to any of the foregoing, (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Secured Obligations, or any other amendment or waiver of or any consent to any departure from the Credit Agreement, any other Loan Document or any other agreement or instrument, (c) any exchange, release or non-perfection of any Lien on other collateral, or any release or amendment or waiver of or consent under or departure from any guarantee, securing or guaranteeing all or any of the Secured Obligations or (d) any other circumstance that might otherwise constitute a defense available to, or a discharge of, any Grantor in respect of the Secured Obligations or this Agreement.

SECTION 6.13. Termination or Release. (a) This Agreement, the Security Interest and all other security interests granted hereby shall terminate with respect to all Secured Obligations when all the outstanding Secured Obligations have been paid in full and the Lenders have no further commitment to lend under the Credit Agreement, the L/C Obligations have been reduced to zero and the L/C Issuers have no further obligations to issue Letters of Credit under the Credit Agreement.

(b) A Grantor (other than the U.S. Borrower) shall automatically be released from its obligations hereunder and the Security Interest in the Collateral of such Grantor shall be automatically released upon the consummation of any transaction permitted by the Credit Agreement as a result of which such Grantor ceases to be a Subsidiary of VNUHF or is otherwise no longer required to be a Grantor hereunder; provided that the Required Lenders shall have consented to such transaction (to the extent required by the Credit Agreement) and the terms of such consent did not provide otherwise.

(c) Upon any sale or other transfer by any Grantor of any Collateral (other than any transfer of Collateral to another Grantor) that is permitted under the Credit Agreement, or upon the effectiveness of any written consent to the release of the security interest granted hereby in any Collateral pursuant to Section 10.01 of the Credit Agreement, the security interest in such Collateral shall be automatically released.

22

(d) In connection with any termination or release pursuant to paragraph (a), (b) or (c), the Collateral Agent shall execute and deliver to any Grantor, at such Grantor’s expense, all documents that such Grantor shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to this Section 6.13 shall be without recourse to or warranty by the Collateral Agent.

SECTION 6.14. Additional Restricted Subsidiaries. Pursuant to Section 6.11 of the Credit Agreement, certain Restricted Subsidiaries of the Loan Parties that were not in existence or not Restricted Subsidiaries on the date of the Credit Agreement are required to enter in this Agreement as a Grantor upon becoming Restricted Subsidiaries. Upon execution and delivery by the Collateral Agent and a Restricted Subsidiary of a Security Agreement Supplement, such Restricted Subsidiary shall become a Grantor hereunder with the same force and effect as if originally named as a Grantor herein. The execution and delivery of any such instrument shall not require the consent of any other Loan Party hereunder. The rights and obligations of each Loan Party hereunder shall remain in full force and effect notwithstanding the addition of any new Loan Party as a party to this Agreement.

SECTION 6.15. Collateral Agent Appointed Attorney-in-Fact. Each Grantor hereby appoints the Collateral Agent the attorney-in-fact of such Grantor for the purpose of carrying out the provisions of this Agreement and taking any action and executing any instrument that the Collateral Agent may deem necessary or advisable to accomplish the purposes hereof at any time after and during the continuance of an Event of Default, which appointment is irrevocable and coupled with an interest. Without limiting the generality of the foregoing, the Collateral Agent shall have the right, upon the occurrence and during the continuance of an Event of Default and notice by the Collateral Agent to the U.S. Borrower of its intent to exercise such rights, with full power of substitution either in the Collateral Agent’s name or in the name of such Grantor (a) to receive, endorse, assign and/or deliver any and all notes, acceptances, checks, drafts, money orders or other evidences of payment relating to the Collateral or any part thereof; (b) to demand, collect, receive payment of, give receipt for and give discharges and releases of all or any of the Collateral; (c) to sign the name of any Grantor on any invoice or bill of lading relating to any of the Collateral; (d) to send verifications of Accounts to any Account Debtor; (e) to commence and prosecute any and all suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect or otherwise realize on all or any of the Collateral or to enforce any rights in respect of any Collateral; (f) to settle, compromise, compound, adjust or defend any actions, suits or proceedings relating to all or any of the Collateral; (g) to notify, or to require any Grantor to notify, Account Debtors to make payment directly to the Collateral Agent; and (h) to use, sell, assign, transfer, pledge, make any agreement with respect to or otherwise deal with all or any of the Collateral, and to do all other acts and things necessary to carry out the purposes of this Agreement, as fully and completely as though the Collateral Agent were the absolute owner of the Collateral for all purposes; provided that nothing herein contained shall be construed as requiring or obligating the Collateral Agent to make any

23

commitment or to make any inquiry as to the nature or sufficiency of any payment received by the Collateral Agent, or to present or file any claim or notice, or to take any action with respect to the Collateral or any part thereof or the moneys due or to become due in respect thereof or any property covered thereby. The Collateral Agent and the other Secured Parties shall be accountable only for amounts actually received as a result of the exercise of the powers granted to them herein, and neither they nor their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct or that of any of their Affiliates, directors, officers, employees, counsel, agents or attorneys-in-fact.

SECTION 6.16. General Authority of the Collateral Agent. By acceptance of the benefits of this Agreement and any other Collateral Documents, each Secured Party (whether or not a signatory hereto) shall be deemed irrevocably (a) to consent to the appointment of the Collateral Agent as its agent hereunder and under such other Collateral Documents, (b) to confirm that the Collateral Agent shall have the authority to act as the exclusive agent of such Secured Party for the enforcement of any provisions of this Agreement and such other Collateral Documents against any Grantor, the exercise of remedies hereunder or thereunder and the giving or withholding of any consent or approval hereunder or thereunder relating to any Collateral or any Grantor’s obligations with respect thereto, (c) to agree that it shall not take any action to enforce any provisions of this Agreement or any other Collateral Document against any Grantor, to exercise any remedy hereunder or thereunder or to give any consents or approvals hereunder or thereunder except as expressly provided in this Agreement or any other Collateral Document and (d) to agree to be bound by the terms of this Agreement and any other Collateral Documents.

A. Reference is made to the Credit Agreement dated as of [                    ], 2006 (as amended, supplemented or otherwise modified from time to time, the “Credit Agreement”), among the U.S. Borrower, VNU Holding & Finance B.V., VNU, Inc., the Guarantors party thereto from time to time, Citibank, N.A., as Administrative Agent, Swing Line Lender and an L/C Issuer, each Lender from time to time party thereto, Deutsche Bank Securities Inc., as Syndication Agent, and JPMorgan Chase Bank, N.A., ABN AMRO Bank N.V. and ING Bank N.V., as Co-Documentation Agents.

B. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Credit Agreement and the Security Agreement referred to therein.

C. The Grantors have entered into the Security Agreement in order to induce the Lenders to make Loans and the L/C Issuers to issue Letters of Credit. Section 6.14 of the Security Agreement provides that additional Restricted Subsidiaries may become Grantors under the Security Agreement by execution and delivery of an instrument in the form of this Supplement. The undersigned Restricted Subsidiary (the “New Subsidiary”) is executing this Supplement in accordance with the requirements of the Credit Agreement to become a Grantor under the Security Agreement in order to induce the Lenders to make additional Loans and the L/C Issuers to issue additional Letters of Credit and as consideration for Loans previously made and Letters of Credit previously issued.

Accordingly, the Collateral Agent and the New Subsidiary agree as follows:

SECTION 1. In accordance with Section 6.14 of the Security Agreement, the New Subsidiary by its signature below becomes a Grantor under the Security Agreement with the same force and effect as if originally named therein as a Grantor and the New Subsidiary hereby (a) agrees to all the terms and provisions of the Security Agreement applicable to it as a Grantor thereunder and (b) represents and warrants that the representations and warranties made by it as a Grantor thereunder are true and correct on and as of the date hereof. In furtherance of the foregoing, the New Subsidiary, as security for the payment and performance in full of the Secured Obligations does hereby create and grant to the Collateral Agent, its successors and assigns, for the benefit of the Secured Parties, their successors and assigns, a security interest in and lien on all of the New Subsidiary’s right, title and interest in and to the Collateral (as defined in the Security Agreement) of the New Subsidiary. Each reference to a “Grantor” in the Security Agreement shall be deemed to include the New Subsidiary. The Security Agreement is hereby incorporated herein by reference.

SECTION 2. The New Subsidiary represents and warrants to the Collateral Agent and the other Secured Parties that this Supplement has been duly authorized, executed and delivered by it and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms.

SECTION 3. This Supplement 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 a single contract. This Supplement shall become effective when the Collateral Agent shall have received a counterpart of this Supplement that bears the signature of the New Subsidiary and the Collateral Agent has executed a counterpart hereof. Delivery of an executed signature page to this Supplement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Supplement.

SECTION 4. The New Subsidiary hereby represents and warrants that (a) set forth on Schedule I attached hereto is a true and correct schedule of the location of any and all Collateral of the New Subsidiary and (b) set forth under its signature hereto is the true and correct legal name of the New Subsidiary, its jurisdiction of formation and the location of its chief executive office.

SECTION 5. Except as expressly supplemented hereby, the Security Agreement shall remain in full force and effect.

SECTION 6. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

SECTION 7. In case any one or more of the provisions contained in this Supplement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and in the Security Agreement shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 8. All communications and notices hereunder shall be in writing and given as provided in Section 6.01 of the Security Agreement.

SECTION 9. The New Subsidiary agrees to reimburse the Collateral Agent for its reasonable out-of-pocket expenses in connection with this Supplement, including the reasonable fees, other charges and disbursements of counsel for the Collateral Agent.

IN WITNESS WHEREOF, the New Subsidiary and the Collateral Agent have duly executed this Supplement to the Security Agreement as of the day and year first above written.
