The Collateral Agent shall have the right, at any time upon the occurrence and during the continuance of any Event of Default, to endorse, assign or otherwise transfer to or to register in the name of the Collateral Agent or any of its nominees or endorse for negotiation any or all of the Securities Collateral, without any indication that such Securities Collateral is subject to

-11-

the security interest hereunder. In addition, upon the occurrence and during the continuance of an Event of Default, the Collateral Agent shall have the right at any time to exchange certificates representing or evidencing Securities Collateral for certificates of smaller or larger denominations.

SECTION 3.2. Perfection of Uncertificated Securities Collateral. Each Pledgor represents and warrants that the Collateral Agent has a perfected first priority security interest in all uncertificated Pledged Securities pledged by it hereunder that are in existence on the date hereof. Each Pledgor hereby agrees that if any of the Pledged Securities are at any time not evidenced by certificates of ownership, then each applicable Pledgor shall, to the extent permitted by applicable law, (i) cause the issuer to execute and deliver to the Collateral Agent an acknowledgment of the pledge of such Pledged Securities substantially in the form of Exhibit 1 hereto, (ii) if necessary or desirable to perfect a security interest in such Pledged Securities, cause such pledge to be recorded on the equityholder register or the books of the issuer, execute any customary pledge forms or other documents necessary or appropriate to complete the pledge and give the Collateral Agent the right to transfer such Pledged Securities under the terms hereof, (iii) upon reasonable request by the Collateral Agent, provide to the Collateral Agent an opinion of counsel, in form and substance reasonably satisfactory to the Collateral Agent, confirming such pledge and perfection thereof, and (iv) after the occurrence and during the continuance of any Event of Default, upon request by the Collateral Agent, (A) to the extent such Pledgor has the ability to do so, cause the Constitutive Documents of such issuer to be amended to provide that such Pledged Securities shall be treated as “securities” for purposes of the UCC and (B) cause such Pledged Securities to become certificated and delivered to the Collateral Agent in accordance with the provisions of Section 3.1.

SECTION 3.3. Financing Statements and Other Filings; Maintenance of Perfected Security Interest. Each Pledgor represents and warrants that all financing statements, agreements, instruments and other documents necessary to perfect the security interest granted by it to the Collateral Agent in respect of the Pledged Collateral have been delivered to the Collateral Agent in completed and, to the extent necessary or appropriate, duly executed form for filing in each governmental, municipal or other office specified in Schedule 7 to the Perfection Certificate. Each Pledgor agrees that at the sole cost and expense of the Pledgors, such Pledgor will maintain the security interest created by this Agreement in the Pledged Collateral as a perfected first priority security interest subject only to Permitted Collateral Liens.

SECTION 3.4. Other Actions. In order to further ensure the attachment, perfection and priority of, and the ability of the Collateral Agent to enforce, the Collateral Agent’s security interest in the Pledged Collateral, each Pledgor represents and warrants (as to itself) as follows and agrees, in each case at such Pledgor’s own expense, to take the following actions with respect to the following Pledged Collateral:

(a) Instruments and Tangible Chattel Paper. As of the date hereof, no amounts payable under or in connection with any of the Pledged Collateral are evidenced by any Instrument or Tangible Chattel Paper other than such Instruments and Tangible Chattel Paper listed in Schedule 11 to the Perfection Certificate. Each Instrument and

-12-

each item of Tangible Chattel Paper listed in Schedule 11 to the Perfection Certificate has been properly endorsed, assigned and delivered to the Collateral Agent, accompanied by instruments of transfer or assignment duly executed in blank. If any amount then payable under or in connection with any of the Pledged Collateral shall be evidenced by any Instrument or Tangible Chattel Paper, and such amount, together with all amounts payable evidenced by any Instrument or Tangible Chattel Paper not previously delivered to the Collateral Agent exceeds $2,000,000 in the aggregate for all Pledgors, the Pledgor acquiring such Instrument or Tangible Chattel Paper shall promptly (but in any event within five days after receipt thereof) endorse, assign and deliver the same to the Collateral Agent, accompanied by such instruments of transfer or assignment duly executed in blank as the Collateral Agent may from time to time specify.

(b) Deposit Accounts. As of the date hereof, no Pledgor has any Deposit Accounts other than the accounts listed in Schedule 14 to the Perfection Certificate. The Collateral Agent has a first priority security interest in each such Deposit Account, which security interest is perfected by Control (except for those Deposit Accounts (the “Excluded Accounts”) (i) for which Control is prohibited by Governmental Authority so long as the balance of each such Deposit Account is swept daily to a Deposit Account subject to the Collateral Agent’s Control, (ii) the available balance of which is swept daily to a Deposit Account subject to the Collateral Agent’s Control or (iii) the balance of which is not swept daily to a Deposit Account subject to the Collateral Agent’s Control and which, in the aggregate, contain no more than 15% of total cash of Borrower and its Subsidiaries at any time); provided that Deposit Accounts of the Acquired Business and its Subsidiaries shall not be included within this representation or in any calculations included herein until 90 days after the Closing Date (or such later date as is determined by the Collateral Agent in its sole discretion). No Pledgor shall change the instructions directing the daily sweep of amounts in the Excluded Accounts to Deposit Accounts subject to the Collateral Agent’s Control. No Pledgor shall hereafter establish and maintain any Deposit Account unless (1) it shall have given the Collateral Agent 30 days’ prior written notice of its intention to establish such new Deposit Account with a Bank, (2) such Bank shall be reasonably acceptable to the Collateral Agent, (3) other than in the case of an Excluded Account, such Bank and such Pledgor shall have duly executed and delivered to the Collateral Agent a Deposit Account Control Agreement with respect to such Deposit Account and (4) in the case of an Excluded Account referenced in clause (i) or (ii) of the definition thereof, the Pledgor shall have issued sweep instructions directing the bank to sweep funds from the Excluded Account to a Deposit Account subject to the Collateral Agent’s Control. The Collateral Agent agrees with each Pledgor that the Collateral Agent shall not give any instructions directing the disposition of funds from time to time credited to any Deposit Account or withhold any withdrawal rights from such Pledgor with respect to funds from time to time credited to any Deposit Account unless an Event of Default has occurred and is continuing. The provisions of this Section 3.4(b) shall not apply to the LC Account or to any other Deposit Accounts for which the Collateral Agent is the Bank. No Pledgor shall grant Control of any Deposit Account to any person other than the Collateral Agent. No Pledgor shall revise or revoke any instructions to a Bank under any Deposit Account Control Agreement without the written consent of the Collateral Agent.

-13-

(c) Investment Property. (i) As of the date hereof, no Pledgor has any Securities Accounts or Commodity Accounts other than those listed in Schedule 14 to the Perfection Certificate. The Collateral Agent has a first priority security interest in each such Securities Account and Commodity Account, which security interest is perfected by Control. No Pledgor shall hereafter establish and maintain any Securities Account or Commodity Account with any Securities Intermediary or Commodity Intermediary unless (1) it shall have given the Collateral Agent 30 days’ prior written notice of its intention to establish such new Securities Account or Commodity Account with such Securities Intermediary or Commodity Intermediary, (2) such Securities Intermediary or Commodity Intermediary shall be reasonably acceptable to the Collateral Agent and (3) such Securities Intermediary or Commodity Intermediary, as the case may be, and such Pledgor shall have duly executed and delivered a Control Agreement with respect to such Securities Account or Commodity Account, as the case may be. Each Pledgor shall accept any cash and Investment Property in trust for the benefit of the Collateral Agent and within one (1) Business Day of actual receipt thereof, deposit any and all Investment Property (other than any Investment Property pledged or to be pledged pursuant to clauses (ii)(1), (iii)(1) or (iii)(3) below) received by it into a Securities Account subject to Collateral Agent’s Control. The Collateral Agent agrees with each Pledgor that the Collateral Agent shall not give any Entitlement Orders or instructions or directions to any issuer of uncertificated securities, Securities Intermediary or Commodity Intermediary, and shall not withhold its consent to the exercise of any withdrawal or dealing rights by such Pledgor, unless an Event of Default has occurred and is continuing or, after giving effect to any such investment and withdrawal rights, would occur. The provisions of this Section 3.4(c) shall not apply to any Financial Assets credited to a Securities Account for which the Collateral Agent is the Securities Intermediary. No Pledgor shall grant Control over any Investment Property owned by such Pledgor to any person other than the Collateral Agent.

(ii) If any Pledgor shall at any time hold or acquire any certificated securities constituting Investment Property, such Pledgor shall by the applicable date specified in Section 6.12 of the Credit Agreement (1) endorse, assign and deliver the same to the Collateral Agent, accompanied by such instruments of transfer or assignment duly executed in blank, all in form and substance reasonably satisfactory to the Collateral Agent or (2) deliver such securities into a Securities Account with respect to which a Securities Account Control Agreement is in effect in favor of the Collateral Agent.

(iii) If any Pledgor shall at any time own or acquire, directly or through a nominee, any uncertificated securities constituting Investment Property, such Pledgor shall by the applicable date specified in Section 6.12 of the Credit Agreement notify the Collateral Agent thereof and pursuant to an agreement in form and substance satisfactory to the Collateral Agent, either (1) cause the issuer to agree to comply with instructions from the Collateral Agent as to such securities, without further consent of any Pledgor or

-14-

such nominee, (2) cause a Security Entitlement with respect to such uncertificated security to be held in a Securities Account with respect to which the Collateral Agent has Control or (3) arrange for the Collateral Agent to become the registered owner of such securities.

(iv) As between the Collateral Agent and the Pledgors, the Pledgors shall bear the investment risk with respect to the Investment Property and Pledged Securities, and the risk of loss of, damage to, or the destruction of the Investment Property and Pledged Securities, whether in the possession of, or maintained as a Security Entitlement or deposit by, or subject to the Control of, the Collateral Agent, a Securities Intermediary, a Commodity Intermediary, any Pledgor or any other person.

(d) Electronic Chattel Paper and Transferable Records. As of the date hereof, no amount under or in connection with any of the Pledged Collateral is evidenced by any Electronic Chattel Paper or any “transferable record” (as that term is defined in Section 201 of the Federal Electronic Signatures in Global and National Commerce Act, or in Section 16 of the Uniform Electronic Transactions Act as in effect in any relevant jurisdiction) other than such Electronic Chattel Paper and transferable records listed in Schedule 11 to the Perfection Certificate. If any amount payable under or in connection with any of the Pledged Collateral shall be evidenced by any Electronic Chattel Paper or any transferable record, the Pledgor acquiring such Electronic Chattel Paper or transferable record shall promptly notify the Collateral Agent thereof and shall take such action as the Collateral Agent may reasonably request to vest in the Collateral Agent control of such Electronic Chattel Paper under Section 9-105 of the UCC or control under Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or, as the case may be, Section 16 of the Uniform Electronic Transactions Act, as so in effect in such jurisdiction, of such transferable record. The requirement in the preceding sentence shall not apply to the extent that such amount, together with all amounts payable evidenced by Electronic Chattel Paper or any transferable record in which the Collateral Agent has not been vested control within the meaning of the statutes described in the immediately preceding sentence, does not exceed $1,000,000 in the aggregate for all Pledgors. The Collateral Agent agrees with such Pledgor that the Collateral Agent will arrange, pursuant to procedures satisfactory to the Collateral Agent and so long as such procedures will not result in the Collateral Agent’s loss of control, for the Pledgor to make alterations to the Electronic Chattel Paper or transferable record permitted under Section 9-105 of the UCC or, as the case may be, Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or Section 16 of the Uniform Electronic Transactions Act for a party in control to allow without loss of control, unless an Event of Default has occurred and is continuing or would occur after taking into account any action by such Pledgor with respect to such Electronic Chattel Paper or transferable record.

(e) Letter-of-Credit Rights. If any Pledgor is at any time a beneficiary under a Letter of Credit now or hereafter issued, such Pledgor shall promptly notify the Collateral Agent thereof and such Pledgor shall, at the request of the Collateral Agent, pursuant to an agreement in form and substance reasonably satisfactory to the Collateral Agent, either

-15-

(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 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, together with the aggregate amount of all other Letters of Credit for which the actions described above in clauses (i) and (ii) have not been taken, does not exceed $5,000,000 in the aggregate for all Pledgors.

(f) Commercial Tort Claims. As of the date hereof, each Pledgor hereby represents and warrants that it holds no Commercial Tort Claims other than those listed in Schedule 13 to the Perfection Certificate. If any Pledgor shall at any time hold or acquire a Commercial Tort Claim, such Pledgor shall immediately notify the Collateral Agent in a writing signed by such Pledgor of the brief details thereof and grant to the Collateral Agent 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. The requirement in the preceding sentence shall not apply to the extent that the amount of such Commercial Tort Claim, together with the amount of all other Commercial Tort Claims held by any Pledgor in which the Collateral Agent does not have a security interest, does not exceed $5,000,000 in the aggregate for all Pledgors.

(g) Motor Vehicles. Upon the request of the Collateral Agent, each Pledgor shall deliver to the Collateral Agent originals of the certificates of title or ownership for the motor vehicles (and any other Equipment covered by certificates of title or ownership) owned by it, with the Collateral Agent listed as lienholder therein. Such requirement shall not apply if any such motor vehicle (or any such other Equipment) is valued at less than $100,000, provided that the aggregate value of all motor vehicles (and such Equipment) as to which any Pledgor has not delivered a certificate of title or ownership is less than $5,000,000.

SECTION 3.5. Joinder of Additional Guarantors. The Pledgors shall cause each Subsidiary of the Borrower which, from time to time, after the date hereof shall be required to pledge any assets to the Collateral Agent for the benefit of the Secured Parties pursuant to the provisions of the Credit Agreement, (a) to execute and deliver to the Collateral Agent (i) a Joinder Agreement substantially in the form of Exhibit 3 hereto by the applicable date specified in Section 6.12 of the Credit Agreement and (ii) at such time a Perfection Certificate or (b) in the case of a Subsidiary organized outside of the United States required to pledge any assets to the Collateral Agent, to execute and deliver to the Collateral Agent such documentation as the Collateral Agent shall reasonably request and, in each case with respect to clauses (a) and (b) above, upon such execution and delivery, such Subsidiary shall constitute a “Guarantor” and a “Pledgor” for all purposes hereunder with the same force and effect as if originally named as a Guarantor and Pledgor herein. The execution and delivery of such Joinder Agreement shall not require the consent of any Pledgor hereunder. The rights and obligations of each Pledgor hereunder shall remain in full force and effect notwithstanding the addition of any new Guarantor and Pledgor as a party to this Agreement.

-16-

SECTION 3.6. Supplements; Further Assurances. Each Pledgor shall take such further actions, and execute and/or deliver to the Collateral Agent such additional financing statements, amendments, assignments, agreements, supplements, powers and instruments, as the Collateral Agent may in its reasonable judgment deem necessary or appropriate in order to create, perfect, preserve and protect the security interest in the Pledged Collateral as provided herein and the rights and interests granted to the Collateral Agent hereunder, to carry into effect the purposes hereof or better to assure and confirm the validity, enforceability and priority of the Collateral Agent’s security interest in the Pledged Collateral or permit the Collateral Agent to exercise and enforce its rights, powers and remedies hereunder with respect to any Pledged Collateral, including the filing of financing statements, continuation statements and other documents (including this Agreement) under the Uniform Commercial Code (or other similar laws) in effect in any jurisdiction with respect to the security interest created hereby and the execution and delivery of Control Agreements, all in form reasonably satisfactory to the Collateral Agent and in such offices (including the United States Patent and Trademark Office and the United States Copyright Office) wherever required by law to perfect, continue and maintain the validity, enforceablity and priority of the security interest in the Pledged Collateral as provided herein and to preserve the other rights and interests granted to the Collateral Agent hereunder, as against third parties, with respect to the Pledged Collateral. Without limiting the generality of the foregoing, each Pledgor shall make, execute, endorse, acknowledge, file or refile and/or deliver to the Collateral Agent from time to time upon reasonable request by the Collateral Agent such lists, schedules, descriptions and designations of the Pledged Collateral, copies of warehouse receipts, receipts in the nature of warehouse receipts, bills of lading, documents of title, vouchers, invoices, schedules, confirmatory assignments, supplements, additional security agreements, conveyances, financing statements, transfer endorsements, powers of attorney, certificates, reports and other assurances or instruments as the Collateral Agent shall reasonably request. If an Event of Default has occurred and is continuing, the Collateral Agent may institute and maintain, in its own name or in the name of any Pledgor, such suits and proceedings as the Collateral Agent may be advised by counsel shall be necessary or expedient to prevent any impairment of the security interest in or the perfection thereof in the Pledged Collateral. All of the foregoing shall be at the sole cost and expense of the Pledgors.

Subject to Section 6.3 of the Credit Agreement, each Pledgor shall, at its own cost and expense, defend title to the Pledged Collateral pledged by it hereunder and the security interest therein and Lien thereon granted to the Collateral Agent and the priority thereof against all claims and demands of all persons, at its own cost and expense, at any time claiming any interest therein adverse to the Collateral Agent or any other Secured Party other than Permitted Collateral Liens. There is no agreement, order, judgment or decree, and no Pledgor shall enter into any agreement or take any other action, that would restrict the transferability of any of the Pledged Collateral or otherwise impair or conflict with such Pledgor’s obligations or the rights of the Collateral Agent hereunder other than actions or agreements granting customary rights to others in the ordinary course of business.

If any Pledgor shall at any time after the date hereof (i) obtain any rights to any additional Intellectual Property Collateral or (ii) become entitled to the benefit of any additional Intellectual Property Collateral or any renewal or extension thereof, including any reissue, division, continuation, or continuation-in-part of any Intellectual Property Collateral, or any improvement on any Intellectual Property Collateral, the provisions hereof shall automatically apply thereto and any such item enumerated in the preceding clause (i) or (ii) shall automatically constitute Intellectual Property Collateral as if such would have constituted Intellectual Property Collateral at the time of execution hereof and be subject to the Lien and security interest created by this Agreement without further action by any party. Each Pledgor shall promptly provide to the Collateral Agent written notice of any of the foregoing with respect to any additional Material Intellectual Property, and confirm the attachment of the Lien and security interest created by this Agreement to any rights described in clauses (i) and (ii) above by execution of an instrument in form reasonably acceptable to the Collateral Agent and the filing of any instruments or statements as shall be reasonably necessary to create, preserve, protect or perfect the Collateral Agent’s security interest in such Intellectual Property Collateral. Further, each Pledgor authorizes the Collateral Agent to modify this Agreement by amending Schedules 12(a) and 12(b) to the Perfection Certificate to include any Intellectual Property Collateral of such Pledgor acquired or arising after the date hereof.

SECTION 6.4. Litigation. Unless there shall occur and be continuing any Event of Default, each Pledgor shall have the right (exercisable in such Pledgor’s commercially reasonable judgment) to commence and prosecute in its own name, as the party in interest, for its own benefit and at the sole cost and expense of the Pledgors, such applications for protection of

-23-

the Intellectual Property Collateral and suits, proceedings or other actions to prevent the infringement, counterfeiting, unfair competition, dilution, diminution in value or other damage as are necessary to protect the Intellectual Property Collateral. Upon the occurrence and during the continuance of any Event of Default and the exercise of the Collateral Agent of its remedies pursuant to Article IX hereof with respect to the Pledged Collateral, the Collateral Agent shall have the right but shall in no way be obligated to file applications for protection of the Intellectual Property Collateral and/or bring suit in the name of any Pledgor, the Collateral Agent or the Secured Parties to enforce the Pledgor’s rights in any Material Intellectual Property Collateral and any license thereunder. In the event of such suit, each Pledgor shall, at the reasonable request of the Collateral Agent, do any and all lawful acts and execute any and all reasonable documents requested by the Collateral Agent in aid of such enforcement and the Pledgors shall promptly reimburse and indemnify the Collateral Agent for all costs and expenses reasonably incurred by the Collateral Agent in the exercise of its rights under this Section 6.4 in accordance with Section 11.5 of the Credit Agreement. In the event that the Collateral Agent shall elect not to bring suit to enforce the Pledgor’s rights in any Material Intellectual Property Collateral, each Pledgor agrees, at the reasonable written request of the Collateral Agent, to take all commercially reasonable actions necessary, whether by suit, proceeding or other action, to prevent the infringement, counterfeiting, unfair competition, dilution, diminution in value of or other damage to any Material Intellectual Property Collateral by any person.

CERTAIN PROVISIONS CONCERNING RECEIVABLES

SECTION 7.1. Maintenance of Records. Each Pledgor shall keep and maintain at its own cost and expense complete records of each Receivable, in a manner consistent with prudent business practice, including records of all payments received, all credits granted thereon, all merchandise returned and all other documentation relating thereto. Each Pledgor shall, at such Pledgor’s sole cost and expense, upon the Collateral Agent’s demand made at any time after the occurrence and during the continuance of any Event of Default, deliver all tangible evidence of Receivables, including all documents evidencing Receivables and any books and records relating thereto to the Collateral Agent or to its representatives (copies of which evidence and books and records may be retained by such Pledgor). Upon the occurrence and during the continuance of any Event of Default, the Collateral Agent may transfer a full and complete copy of any Pledgor’s books, records, credit information, reports, memoranda and all other writings relating to the Receivables to and for the use by any person that has acquired or is contemplating acquisition of an interest in the Receivables or the Collateral Agent’s security interest therein without the consent of any Pledgor provided that such person agrees to confidentiality provisions substantially similar to those set forth in Section 11.15 of the Credit Agreement.

SECTION 7.2. Legend. Each Pledgor shall legend, at the request of the Collateral Agent and in form and manner satisfactory to the Collateral Agent, the Receivables and the other books, records and documents of such Pledgor evidencing or pertaining to the Receivables

-24-

with an appropriate reference to the fact that the Receivables have been assigned to the Collateral Agent for the benefit of the Secured Parties and that the Collateral Agent has a security interest therein.

SECTION 7.3. Modification of Terms, etc. No Pledgor shall rescind or cancel any obligations evidenced by any Receivable or modify any term thereof or make any adjustment with respect thereto except in the ordinary course of business consistent with prudent business practice, or extend or renew any such obligations except in the ordinary course of business consistent with prudent business practice or compromise or settle any dispute, claim, suit or legal proceeding relating thereto or sell any Receivable or interest therein except in the ordinary course of business consistent with prudent business practice without the prior written consent of the Collateral Agent. Each Pledgor shall timely fulfill all obligations on its part to be fulfilled under or in connection with the Receivables except to the extent such Pledgor determines such action is not appropriate or advisable consistent with prudent business practice in the ordinary course of business.

SECTION 7.4. Collection. Each Pledgor shall cause to be collected from the Account Debtor of each of the Receivables, as and when due in the ordinary course of business and consistent with prudent business practice (including Receivables that are delinquent, such Receivables to be collected in accordance with generally accepted commercial collection procedures), any and all amounts owing under or on account of such Receivable, and apply forthwith upon receipt thereof all such amounts as are so collected to the outstanding balance of such Receivable, except that any Pledgor may, with respect to a Receivable, allow in the ordinary course of business (i) a refund or credit due as a result of returned or damaged or defective merchandise and (ii) such extensions of time to pay amounts due in respect of Receivables and such other modifications of payment terms or settlements in respect of Receivables as shall be commercially reasonable in the circumstances, all in accordance with such Pledgor’s ordinary course of business consistent with its collection practices as in effect from time to time. The costs and expenses (including attorneys’ fees) of collection, in any case, whether incurred by any Pledgor, the Collateral Agent or any Secured Party, shall be paid by the Pledgors.

ARTICLE IX

REMEDIES

SECTION 9.1. Remedies. Upon the occurrence and during the continuance of any Event of Default, the Collateral Agent may from time to time exercise in respect of the Pledged Collateral, in addition to the other rights and remedies provided for herein or otherwise available to it, the following remedies:

(i) To the fullest extent permitted by applicable law, personally, or by agents or attorneys, immediately take possession of the Pledged Collateral or any part thereof, from any Pledgor or any other person who then has possession of any part thereof with or without notice or process of law, and for that purpose may enter upon any Pledgor’s premises where any of the Pledged Collateral is located, remove such Pledged Collateral, remain present at such premises to receive copies of all communications and remittances relating to the Pledged Collateral and use in connection with such removal and possession any and all services, supplies, aids and other facilities of any Pledgor;

(ii) Demand, ▇▇▇ for, collect or receive any money or property at any time payable or receivable in respect of the Pledged Collateral including instructing the obligor or obligors on any agreement, instrument or other obligation constituting part of the Pledged Collateral to make any payment required by the terms of such agreement, instrument or other obligation directly to the Collateral Agent, and in connection with any of the foregoing, compromise, settle, extend the time for payment and make other modifications with respect thereto; provided, however, that in the event that any such payments are made directly to any Pledgor, prior to receipt by any such obligor of such instruction, such Pledgor shall segregate all amounts received pursuant thereto in trust for the benefit of the Collateral Agent and shall promptly (but in no event later than one (1) Business Day after receipt thereof) pay such amounts to the Collateral Agent;

(iii) Subject to Section 6.1, sell, assign, grant a license to use or otherwise liquidate, or direct any Pledgor to sell, assign, grant a license to use or otherwise liquidate, any and all investments made in whole or in part with the Pledged Collateral or any part thereof, and take possession of the proceeds of any such sale, assignment, license or liquidation;

(iv) Take possession of the Pledged Collateral or any part thereof, by directing any Pledgor in writing to deliver the same to the Collateral Agent at any place or places so designated by the Collateral Agent, in which event such Pledgor shall at its own expense: (A) forthwith cause the same to be moved to the place or places designated by the Collateral Agent and therewith delivered to the Collateral Agent, (B) store and keep any Pledged Collateral so delivered to the Collateral Agent at such place or places pending further action by the Collateral Agent and (C) while the Pledged Collateral shall be so stored and kept, provide such security and maintenance services as shall be necessary to protect the same and to preserve and maintain them in good condition. Each Pledgor’s obligation to deliver the Pledged Collateral as contemplated

-26-

plated in this Section 9.1(iv) is of the essence hereof. Upon application to a court of equity having jurisdiction, the Collateral Agent shall be entitled to a decree requiring specific performance by any Pledgor of such obligation;

(v) Withdraw all moneys, instruments, securities and other property in any bank, financial securities, deposit or other account of any Pledgor constituting Pledged Collateral for application to the Secured Obligations as provided in Article X hereof;

(vi) Retain and apply the Distributions to the Secured Obligations as provided in Article X hereof;

(vii) Exercise any and all rights as beneficial and legal owner of the Pledged Collateral, including perfecting assignment of and exercising any and all voting, consensual and other rights and powers with respect to any Pledged Collateral; and

(viii) Subject to Section 6.1, exercise all the rights and remedies of a secured party on default under the UCC, and the Collateral Agent may also in its sole discretion, without notice except as specified in Section 9.2 hereof, sell, assign or grant a license to use the Pledged Collateral or any part thereof in one or more parcels at public or private sale, at any exchange, broker’s board or at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and at such price or prices and upon such other terms as the Collateral Agent may deem commercially reasonable. The Collateral Agent or any other Secured Party or any of their respective Affiliates may be the purchaser, licensee, assignee or recipient of the Pledged Collateral or any part thereof at any such public sale, and to the fullest extent permitted by applicable law, private sale and shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Pledged Collateral sold, assigned or licensed at such sale, to use and apply any of the Secured Obligations owed to such person as a credit on account of the purchase price of the Pledged Collateral or any part thereof payable by such person at such sale. Each purchaser, assignee, licensee or recipient at any such sale shall acquire the property sold, assigned or licensed absolutely free from any claim or right on the part of any Pledgor, and each Pledgor hereby waives, to the fullest extent permitted by law, all rights of redemption, stay and/or appraisal which it 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 not be obligated to make any sale of the Pledged Collateral or any part thereof regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. Each Pledgor hereby waives, to the fullest extent permitted by law, any claims against the Collateral Agent arising by reason of the fact that the price at which the Pledged Collateral or any part thereof may have been sold, assigned or licensed at such a private sale was less than the price which might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer such Pledged Collateral to more than one offeree.

SECTION 9.2. Notice of Sale. Each Pledgor acknowledges and agrees that, to the extent notice of sale or other disposition of the Pledged Collateral or any part thereof shall be

-27-

required by law, ten (10) days’ prior notice to such Pledgor of the time and place of any public sale or of the time after which any private sale or other intended disposition is to take place shall be commercially reasonable notification of such matters. No notification need be given to any Pledgor if it has signed, after the occurrence of an Event of Default, a statement renouncing or modifying any right to notification of sale or other intended disposition.

SECTION 9.3. Waiver of Notice and Claims. Each Pledgor hereby waives, to the fullest extent permitted by applicable law, notice or judicial hearing in connection with the Collateral Agent’s taking possession or the Collateral Agent’s disposition of the Pledged Collateral or any part thereof, including any and all prior notice and hearing for any prejudgment remedy or remedies and any such right which such Pledgor would otherwise have under law, and each Pledgor hereby further waives, to the fullest extent permitted by applicable law: (i) all damages occasioned by such taking of possession, (ii) all other requirements as to the time, place and terms of sale or other requirements with respect to the enforcement of the Collateral Agent’s rights hereunder and (iii) all rights of redemption, appraisal, valuation, stay, extension or moratorium now or hereafter in force under any applicable law. The Collateral Agent shall not be liable for any incorrect or improper payment made pursuant to this Article IX in the absence of gross negligence or willful misconduct on the part of the Collateral Agent. Any sale of, or the grant of options to purchase, or any other realization upon, any Pledged Collateral shall operate to divest all right, title, interest, claim and demand, either at law or in equity, of the applicable Pledgor therein and thereto, and shall be a perpetual bar both at law and in equity against such Pledgor and against any and all persons claiming or attempting to claim the Pledged Collateral so sold, optioned or realized upon, or any part thereof, from, through or under such Pledgor.

SECTION 9.4. Certain Sales of Pledged Collateral.

(a) Each Pledgor recognizes that, by reason of certain prohibitions contained in law, rules, regulations or orders of any Governmental Authority, the Collateral Agent may be compelled, with respect to any sale of all or any part of the Pledged Collateral, to limit purchasers to those who meet the requirements of such Governmental Authority. Each Pledgor acknowledges that any such sales may be at prices and on terms less favorable to the Collateral Agent than those obtainable through a public sale without such restrictions, and, notwithstanding such circumstances, agrees that any such restricted sale shall not be deemed to have not been made in a commercially reasonable manner solely because it was conducted as a private sale and that, except as may be required by applicable law, the Collateral Agent shall have no obligation to engage in public sales.

(b) Each Pledgor recognizes that, by reason of certain prohibitions contained in the Securities Act of 1933, as amended (the “Securities Act”), and applicable state securities laws, the Collateral Agent may be compelled, with respect to any sale of all or any part of the Securities Collateral and Investment Property, to limit purchasers to persons who will agree, among other things, to acquire such Securities Collateral or Investment Property 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 at prices and on terms less favorable to the Collateral Agent than those obtainable through a public sale without such restrictions (including a

-28-

public offering made pursuant to a registration statement under the Securities Act), and, notwithstanding such circumstances, agrees that any such private sale shall not be deemed to have not been made in a commercially reasonable manner solely because it was conducted as a private sale, and that the Collateral Agent shall have no obligation to engage in public sales and no obligation to delay the sale of any Securities Collateral or Investment Property for the period of time necessary to permit the issuer thereof to register it for a form of public sale requiring registration under the Securities Act or under applicable state securities laws, even if such issuer would agree to do so.

(c) Notwithstanding the foregoing, each Pledgor shall, upon the occurrence and during the continuance of any Event of Default, at the reasonable request of the Collateral Agent, for the benefit of the Collateral Agent, cause any registration, qualification statement or application under or compliance with any Federal or state securities law or laws to be prepared and filed with respect to all or any part of the Securities Collateral as soon as practicable and at the sole cost and expense of the Pledgors. Each Pledgor will use its commercially reasonable efforts to cause such registration to be effected (and be kept effective) and will use its commercially reasonable efforts to cause such qualification and compliance to be effected (and be kept effective) as may be so requested and as would permit or facilitate the sale and distribution of such Securities Collateral including registration under the Securities Act (or any similar statute then in effect), appropriate qualifications under applicable blue sky or other state securities laws and appropriate compliance with all other requirements of any Governmental Authority. Each Pledgor shall use its commercially reasonable efforts to cause the Collateral Agent to be kept advised in writing as to the progress of each such registration, qualification or compliance and as to the completion thereof, shall furnish to the Collateral Agent such number of prospectuses, offering circulars or other documents incident thereto as the Collateral Agent from time to time may request, and shall indemnify and shall cause the issuer of the Securities Collateral to indemnify the Collateral Agent and all others participating in the distribution of such Securities Collateral against all claims, losses, damages and liabilities caused by any untrue statement (or alleged untrue statement) of a material fact contained therein (or in any related registration statement, notification or the like) or by any omission (or alleged omission) to state therein (or in any related registration statement, notification or the like) a material fact required to be stated therein or necessary to make the statements therein not misleading other than any such statement or omission made in reliance on, and in conformity with, written information provided to such Pledgor by Collateral Agent or any other participant in the distribution for inclusion therein.

(d) If the Collateral Agent determines to exercise its right to sell any or all of the Securities Collateral or Investment Property, upon written request, the applicable Pledgor shall from time to time furnish to the Collateral Agent all such information as the Collateral Agent may request in order to determine the number of securities included in the Securities Collateral or Investment Property which may be sold by the Collateral Agent as exempt transactions under the Securities Act and the rules of the SEC thereunder, as the same are from time to time in effect.

(e) Each Pledgor further agrees that a breach of any of the covenants contained in this Section 9.4 will cause irreparable injury to the Collateral Agent and the other Secured

-29-

cured Parties, that the Collateral 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 9.4 shall be specifically enforceable against such Pledgor, and such Pledgor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred and is continuing.

SECTION 9.5. No Waiver; Cumulative Remedies.

(a) No failure on the part of the Collateral Agent to exercise, no course of dealing with respect to, and no delay on the part of the Collateral Agent in exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right, power, privilege or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power, privilege or remedy; nor shall the Collateral Agent be required to look first to, enforce or exhaust any other security, collateral or guaranties. All rights and remedies herein provided are cumulative and are not exclusive of any rights or remedies provided by law or otherwise available.

(b) In the event that the Collateral Agent shall have instituted any proceeding to enforce any right, power, privilege or remedy under this Agreement or any other Loan Document by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Collateral Agent, then and in every such case, the Pledgors, the Collateral Agent and each other Secured Party shall be restored to their respective former positions and rights hereunder with respect to the Pledged Collateral, and all rights, remedies, privileges and powers of the Collateral Agent and the other Secured Parties shall continue as if no such proceeding had been instituted.

SECTION 9.6. Certain Additional Actions Regarding Intellectual Property. If any Event of Default shall have occurred and be continuing, upon the written demand of the Collateral Agent, each Pledgor shall execute and deliver to the Collateral Agent an assignment or assignments of the registered Patents, Trademarks and/or Copyrights and Goodwill and such other documents as are necessary or appropriate to carry out the intent and purposes hereof. Within five (5) Business Days of written notice thereafter from the Collateral Agent, each Pledgor shall make available to the Collateral Agent, to the extent within such Pledgor’s power and authority, such personnel in such Pledgor’s employ on the date of the Event of Default as the Collateral Agent may reasonably designate to permit such Pledgor to continue, directly or indirectly, to produce, advertise and sell the products and services sold by such Pledgor under the registered Patents, Trademarks and/or Copyrights, and such persons shall be available to perform their prior functions on the Collateral Agent’s behalf.

The proceeds received by the Collateral Agent in respect of any sale of, collection from or other realization upon all or any part of the Pledged Collateral pursuant to the exercise by the Collateral Agent of its remedies shall be applied, together with any other sums then held by the Collateral Agent pursuant to this Agreement, in accordance with the Credit Agreement.

ARTICLE XI

MISCELLANEOUS

SECTION 11.1. Concerning Collateral Agent.

(a) The Collateral Agent has been appointed as collateral agent pursuant to the Credit Agreement. The actions of the Collateral Agent hereunder are subject to the provisions of the Credit Agreement. The Collateral Agent shall have the right hereunder to make demands, to give notices, to exercise or refrain from exercising any rights, and to take or refrain from taking action (including the release or substitution of the Pledged Collateral), in accordance with this Agreement and the Credit Agreement. The Collateral Agent may employ agents and attorneys-in-fact in connection herewith and shall not be liable for the negligence or misconduct of any such agents or attorneys-in-fact selected by it in good faith. The Collateral Agent may resign and a successor Collateral Agent may be appointed in the manner provided in the Credit Agreement. Upon the acceptance of any appointment as the Collateral Agent by a successor Collateral Agent, that successor Collateral Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent under this Agreement, and the retiring Collateral Agent shall thereupon be discharged from its duties and obligations under this Agreement. After any retiring Collateral Agent’s resignation, the provisions hereof shall inure to its benefit as to any actions taken or omitted to be taken by it under this Agreement while it was the Collateral Agent.

(b) The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Pledged Collateral in its possession if such Pledged Collateral is accorded treatment substantially equivalent to that which the Collateral Agent, in its individual capacity, accords its own property consisting of similar instruments or interests, it being understood that neither the Collateral Agent nor any of the Secured Parties shall have responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to any Securities Collateral, whether or not the Collateral Agent or any other Secured Party has or is deemed to have knowledge of such matters or (ii) taking any necessary steps to preserve rights against any person with respect to any Pledged Collateral.

-31-

(c) The Collateral Agent shall be entitled to rely upon any written notice, statement, certificate, order or other document or any telephone message believed by it to be genuine and correct and to have been signed, sent or made by the proper person, and, with respect to all matters pertaining to this Agreement and its duties hereunder, upon advice of counsel selected by it.

(d) If any item of Pledged Collateral also constitutes collateral granted to the Collateral Agent under any other deed of trust, mortgage, security agreement, pledge or instrument of any type, in the event of any conflict between the provisions hereof and the provisions of such other deed of trust, mortgage, security agreement, pledge or instrument of any type in respect of such collateral, the Collateral Agent, in its sole discretion, shall select which provision or provisions shall control.

SECTION 11.2. Collateral Agent May Perform; Collateral Agent Appointed Attorney-in-Fact. If any Pledgor shall fail to perform any covenants contained in this Agreement (including such Pledgor’s covenants to (i) pay the premiums in respect of all required insurance policies hereunder, (ii) pay and discharge any taxes, assessments and special assessments, levies, fees and governmental charges imposed upon or assessed against, and landlords’, carriers’, mechanics’, workmen’s, repairmen’s, laborers’, materialmen’s, suppliers’ and warehousemen’s Liens and other claims arising by operation of law against, all or any portion of the Pledged Collateral, (iii) make repairs, (iv) discharge Liens or (v) pay or perform any obligations of such Pledgor under any Pledged Collateral) or if any representation or warranty on the part of any Pledgor contained herein shall be breached, the Collateral Agent may (but shall not be obligated to) do the same or cause it to be done or remedy any such breach, and may expend funds for such purpose; provided, however, that (a) in the case of clauses (ii) and (iv) the Collateral Agent shall not make such payment or discharge any Lien arising out of any tax, assessment, charge or claim that is being contested in good faith and by proper proceedings and as to which appropriate reserves are being maintained in accordance with GAAP, unless and until such Lien attaches to such Pledgor’s property and becomes enforceable against such Pledgor’s other creditors and subjects the property to a substantial risk of forfeiture and (b) the Collateral Agent shall in no event be bound to inquire into the validity of any tax, Lien, imposition or other obligation which such Pledgor fails to pay or perform as and when required hereby and which such Pledgor does not contest in accordance with the provisions of the Credit Agreement. Any and all amounts so expended by the Collateral Agent shall be paid by the Pledgors in accordance with the provisions of Section 11.5 of the Credit Agreement. Neither the provisions of this Section 11.2 nor any action taken by the Collateral Agent pursuant to the provisions of this Section 11.2 shall prevent any such failure to observe any covenant contained in this Agreement nor any breach of representation or warranty from constituting an Event of Default. Each Pledgor hereby appoints the Collateral Agent its attorney-in-fact, with full power and authority in the place and stead of such Pledgor and in the name of such Pledgor, or otherwise, from time to time in the Collateral Agent’s discretion to take any action and to execute any instrument consistent with the terms of the Credit Agreement, this Agreement and the other Security Documents which the Collateral Agent may deem necessary or advisable to accomplish the purposes hereof (but the Collateral Agent shall not be obligated to and shall have no liability to such Pledgor or any third

-32-

party for failure to so do or take action). The foregoing grant of authority is a power of attorney coupled with an interest and such appointment shall be irrevocable for the term hereof. Each Pledgor hereby ratifies all that such attorney shall lawfully do or cause to be done by virtue hereof.

SECTION 11.3. Continuing Security Interest; Assignment. This Agreement shall create a continuing security interest in the Pledged Collateral and shall (i) be binding upon the Pledgors, their respective successors and assigns and (ii) inure, together with the rights and remedies of the Collateral Agent hereunder, to the benefit of the Collateral Agent and the other Secured Parties and each of their respective successors, transferees and assigns. No other persons (including any other creditor of any Pledgor) shall have any interest herein or any right or benefit with respect hereto. Without limiting the generality of the foregoing clause (ii), any Secured Party may assign or otherwise transfer any indebtedness held by it secured by this Agreement to any other person, and such other person shall thereupon become vested with all the benefits in respect thereof granted to such Secured Party, herein or otherwise, subject however, to the provisions of the Credit Agreement and, in the case of a Secured Party that is a party to a Specified Swap Agreement or Operating Indebtedness Agreement, such Specified Swap Agreement or Operating Indebtedness Agreement.

SECTION 11.4. Termination; Release. (a) When all the Secured Obligations have been paid in full (other than inchoate indemnification and cost reimbursement obligations not then due) and the Commitments of the Lenders to make any Loan or to issue any Letter of Credit under the Credit Agreement shall have expired or been sooner terminated and all Letters of Credit have been terminated or cash collateralized in accordance with the provisions of the Credit Agreement, this Agreement shall terminate. Upon termination of this Agreement the Pledged Collateral shall be released from the Lien of this Agreement and upon the sale by any Pledgor of any Pledged Collateral in accordance with Section 7.5 of the Credit Agreement, such Pledged Collateral shall be released from the Lien of this Agreement. Upon such release or any release of Pledged Collateral or any part thereof in accordance with the provisions of the Credit Agreement, the Collateral Agent shall, upon the request and at the sole cost and expense of the Pledgors, assign, transfer and deliver to Pledgor, against receipt and without recourse to or warranty by the Collateral Agent except as to the fact that the Collateral Agent has not encumbered the released assets, such of the Pledged Collateral or any part thereof to be released (in the case of a release) as may be in possession of the Collateral Agent and as shall not have been sold or otherwise applied pursuant to the terms hereof, and, with respect to any other Pledged Collateral, proper documents and instruments (including UCC-3 termination financing statements or releases) acknowledging the termination hereof or the release of such Pledged Collateral, as the case may be.

(b) Notwithstanding Section 2.1, in connection with the granting of a Lien permitted by Section 7.1(d) of the Credit Agreement in any Real Property or Equipment owned by a Pledgor or with the disposition of Receivables Assets of a Pledgor permitted by Section 7.5(i) of the Credit Agreement pursuant to a Permitted Receivables Financing, the Collateral Agent shall, at such Pledgor’s request if required by the lender or lessor providing Debt to be secured by such Lien or such Receivables Assets, as applicable, at such Pledgor’s expense, execute

-33-

and deliver such documents as such Pledgor shall reasonably request to evidence the release of such item or items of Pledged Collateral from the Lien of this Agreement; provided, however, that such Pledgor shall have delivered to the Collateral Agent, at least three Business Days prior to the date of the proposed realease, a written request decribing the items of Collateral, together with a form of release for execution by the Collateral Agent, and a certificate of the chief financial officer of such Pledgor to the effect that the transaction is in compliance with the Credit Agreement and as to such other matters as the Collateral Agent may reasonably request.

SECTION 11.5. Modification in Writing. No amendment, modification, supplement, termination or waiver of or to any provision hereof, nor consent to any departure by any Pledgor therefrom, shall be effective unless the same shall be made in accordance with the terms of the Credit Agreement and unless in writing and signed by the Collateral Agent. Any amendment, modification or supplement of or to any provision hereof, any waiver of any provision hereof and any consent to any departure by any Pledgor from the terms of any provision hereof in each case shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement or any other document evidencing the Secured Obligations, no notice to or demand on any Pledgor in any case shall entitle any Pledgor to any other or further notice or demand in similar or other circumstances.

SECTION 11.6. Notices. Unless otherwise provided herein or in the Credit Agreement, any notice or other communication herein required or permitted to be given shall be given in the manner and become effective as set forth in the Credit Agreement, as to any Pledgor, addressed to it at the address of the Borrower set forth in the Credit Agreement and as to the Collateral Agent, addressed to it at the address set forth in the Credit Agreement, or in each case at such other address as shall be designated by such party in a written notice to the other party complying as to delivery with the terms of this Section 11.6.
