Until one year and one day after the Termination Date, each Grantor hereby irrevocably waives any claim or other rights which it may now or hereafter acquire against any Obligor that arise from the existence, payment, performance or enforcement of such Grantor’s obligations under this Security Agreement or any other Indenture Document, including any right of subrogation, reimbursement, exoneration or indemnification, any right to participate in any claim or remedy of any Secured Party against any Obligor or any collateral which any Secured Party now has or hereafter acquires, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including the right to take or receive from any Obligor, directly or indirectly, in cash or other property or by set-off or in any manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Grantor in violation of the preceding sentence and the Secured Obligations shall not have been indefeasibly paid in full in cash, then, subject to the rights and interests of the holders of any Senior Obligations, such amount shall be deemed to have been paid to such Grantor for the benefit of, and held in trust for, the Collateral Agent (on behalf of the Secured Parties), and shall forthwith be paid to the Collateral Agent to be credited and applied upon the

-12-

Secured Obligations, whether matured or unmatured. Each Grantor acknowledges that it will receive direct and indirect benefits from the issuance of the Notes as contemplated by the Exchange Agreement and that the waiver set forth in this Section 2.8 is knowingly made in contemplation of such benefits.

SECTION 2.9. Election of Remedies. Except as otherwise provided in the Indenture, if any Secured Party may, under applicable law, proceed to realize its benefits under any of this Security Agreement or the other Indenture Documents giving any Secured Party a Lien upon any Collateral, either by judicial foreclosure or by non-judicial sale or enforcement, such Secured Party may, at its sole option, determine which of its remedies or rights it may pursue without affecting any of its rights and remedies under this Security Agreement. If, in the exercise of any of its rights and remedies, any Secured Party shall forfeit any of its rights or remedies, including its right to enter a deficiency judgment against any Obligor or any other Person, whether because of any applicable laws pertaining to “election of remedies” or the like, each Grantor hereby consents to such action by such Secured Party and waives any claim based upon such action, even if such action by such Secured Party shall result in a full or partial loss of any rights of subrogation that such Grantor might otherwise have had but for such action by such Secured Party.

With respect to Certificated Equipment now or hereafter owned by a Grantor, such Grantor shall be required to deliver such title to a Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) and, if such title is required to have been delivered to the Collateral Agent, take any other action necessary to enable the Collateral Agent to perfect its Lien in such Equipment, including endorsing certificates of title or executing applications for transfer of title, as is reasonably required by the Collateral Agent to enable it to properly perfect and protect its Lien on such Certificated Equipment and to transfer the same.

-23-

(b) such Grantor shall promptly notify the Collateral Agent if it knows that any application or registration relating to any material item of the Intellectual Property Collateral may become abandoned or dedicated to the public or placed in the public domain or invalid or unenforceable, or of any adverse determination or development (including the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, the United States Copyright Office or any foreign counterpart thereof or any court) regarding such Grantor’s ownership of any of the Intellectual Property Collateral, its right to register the same or to keep and maintain and enforce the same;

(c) in no event will such Grantor or any of its agents, employees, designees or licensees file an application for the registration of any material Intellectual Property Collateral with the United States Patent and Trademark Office, the United States Copyright Office or any similar office or agency in any other country or any political subdivision thereof, unless it promptly informs the Collateral Agent, and upon request of the Collateral Agent (subject to the terms of the Indenture), executes and delivers all agreements, instruments and documents as the Collateral Agent may reasonably request to evidence the Collateral Agent’s security interest in such Intellectual Property Collateral;

(d) such Grantor will take all necessary steps, including in any proceeding before the United States Patent and Trademark Office, the United States Copyright Office or (subject to the terms of the Indenture) any similar office or agency in any other country or any political subdivision thereof, to maintain and pursue any application (and to obtain the relevant registration) filed with respect to, and to maintain any registration of, each material Intellectual Property Collateral, including the filing of applications for renewal, affidavits of use, affidavits of incontestability and opposition, interference and cancellation proceedings and the payment of fees and taxes (except to the extent that dedication, abandonment or invalidation is permitted under the foregoing clause (a) or (b));

(e) following the obtaining of an interest in any material Intellectual Property by such Grantor, such Grantor shall deliver a supplement to Schedule II identifying such new Intellectual Property; and

-24-

SECTION 4.7. As to Letter-of-Credit Rights.

(a) Each Grantor, by granting a security interest in its Letter-of-Credit Rights to the Collateral Agent, intends to (and hereby does) collaterally assign to the Collateral Agent its rights (including its contingent rights ) to the Proceeds of all Letter-of-Credit Rights of which it is or hereafter becomes a beneficiary or assignee. Promptly following the date on which any Grantor obtains any Letter of Credit Rights after the date hereof, such Grantor shall (i) deliver a supplement to Schedule II identifying such new Letter-of-Credit Right and (ii) with respect to Letter of Credit Rights in excess of $250,000 cause the issuer of each Letter of Credit and each nominated person (if any) with respect thereto to consent to the assignment of the Proceeds thereof to a Senior Collateral Agent (and, after the Discharge of Senior Obligations, the Collateral Agent) in a consent agreement in form and substance reasonably satisfactory to such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) and deliver written evidence of such consent to the Collateral Agent.

(b) During the existence of an Event of Default, each Grantor will, promptly upon request by a Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent), (i) notify (and each Grantor hereby authorizes such Senior Collateral Agent (or , after the Discharge of Senior Obligations, the Collateral Agent) to notify) the issuer and each nominated person with respect to each of the Letters of Credit that the Proceeds thereof have been assigned to such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) and any payments due or to become due in respect thereof are to be made directly to such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) and (ii) arrange for such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) to become the transferee beneficiary Letter of Credit.

SECTION 4.8. As to Commercial Tort Claims. Each Grantor covenants and agrees that, until the Termination Date, with respect to any Commercial Tort Claim in excess of $250,000 individually or in the aggregate hereafter arising, it shall deliver to the Collateral Agent a supplement to Schedule II in form and substance reasonably satisfactory to the Collateral Agent, identifying such new Commercial Tort Claims.

SECTION 4.9. Electronic Chattel Paper and Transferable Records. If any Grantor at any time holds or acquires an interest in any electronic chattel paper or any “transferable record,” as that term is defined in Section 201 of the U.S. Federal Electronic Signatures in Global and National Commerce Act, or in Section 16 of the U.S. Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, with a value in excess of $250,000, such Grantor shall promptly notify the Collateral Agent thereof and, at the request of a Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent), shall take such action as such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) may request to vest in such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) control (for the ratable benefit of Secured Parties) under Section 9-105 of the UCC of such electronic chattel paper 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

-25-

record. The Collateral Agent agrees with each Grantor that, if such control has been vested in it, the Collateral Agent will arrange, pursuant to procedures reasonably satisfactory to the Collateral Agent and so long as such procedures will not result in the Collateral Agent’s loss of control, for such Grantor 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 U.S. Federal Electronic Signatures in Global and National Commerce Act or Section 16 of the U.S. 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 Grantor with respect to such electronic chattel paper or transferable record.

SECTION 4.10. Transfers and Other Liens. No Grantor shall: (a) sell, assign (by operation of law or otherwise) or otherwise dispose of any of the Collateral, except Inventory in the ordinary course of business or as specifically permitted by the Indenture or any Senior Obligations Governing Documents, or (b) create or suffer to exist any Lien or other charge or encumbrance upon or with respect to any of the Collateral to secure Debt of any Person or entity, except for the security interest created by this Security Agreement and except for Permitted Liens.

SECTION 4.11. Taxes. Each Grantor agrees to comply in all material respects with all applicable law, including the appropriate payment (before the same become delinquent), by, or on behalf of, such Grantor of all taxes imposed upon such Grantor or any of its direct or indirect Subsidiaries or upon their property except to the extent being diligently contested in good faith by appropriate proceedings and for which adequate reserves in accordance with GAAP have been set aside on the books of such Grantor or such Subsidiaries, as applicable.

SECTION 4.12. Further Assurances, etc. Each Grantor shall warrant and defend the right, title and interest herein granted unto the Collateral Agent in and to the Collateral (and all right, title and interest represented by the Collateral) against the claims and demands of all Persons whomsoever. Each Grantor agrees that, from time to time at its own expense, it will promptly execute and deliver all further instruments and documents, and take all further action, that may be necessary or that the Collateral Agent may reasonably request, in order to perfect, preserve and protect the security interest granted or purported to be granted hereby in all material portions of the Collateral (subject to the terms hereof and of the Indenture and the Intercreditor Agreement) or to enable the Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Each Grantor agrees that, upon the acquisition after the date hereof by such Grantor of any Collateral, with respect to which the security interest granted hereunder is not perfected automatically upon such acquisition, to take such actions with respect to such Collateral or any part thereof as required by the Indenture Documents. Without limiting the generality of the foregoing, each Grantor will:

(a) from time to time upon the request of a Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent), promptly deliver to such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) such stock powers, instruments and similar documents, reasonably satisfactory in form and substance to such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent), with respect to such Collateral as such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) may

-26-

reasonably request and will from time to time upon the request of a Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent), after the occurrence and during the continuance of any Event of Default, promptly transfer any securities constituting Collateral into the name of any nominee designated by such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent); if any Collateral shall be evidenced by an Instrument, negotiable Document, Promissory Note or tangible Chattel Paper, deliver and pledge to a Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) such Instrument, negotiable Document, Promissory Note, Pledged Note or tangible Chattel Paper duly endorsed and accompanied by duly executed instruments of transfer or assignment, all in form and substance reasonably satisfactory to such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent);

(b) file (and hereby authorizes the Collateral Agent to file after delivery of a copy thereof to such Grantor) such filing statements or continuation statements, or amendments thereto, and such other instruments or notices (including any assignment of claim form under or pursuant to the federal assignment of claims statute, 31 U.S.C. § 3726, any successor or amended version thereof or any regulation promulgated under or pursuant to any version thereof), as may be necessary or that the Collateral Agent may request in order to perfect and preserve the security interests and other rights granted or purported to be granted to the Collateral Agent hereby. The authorization contained in this Section 4.12 shall be irrevocable and continuing until the Termination Date;

(c) deliver to a Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) and at all times keep pledged to the Collateral Agent pursuant hereto, on a first-priority, perfected basis (except for Permitted Liens), at the request of such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent), all Investment Property constituting Collateral, all Distributions with respect thereto (which shall only be delivered to a Senior Collateral Agent or the Collateral Agent during the continuance of a Default), and all interest and principal with respect to Promissory Notes, and all Proceeds and rights from time to time received by or distributable to such Grantor in respect of any of the foregoing Collateral;

(d) not take or omit to take any action the taking or the omission of which would result in any impairment or alteration of any obligation of the maker of any Payment Intangible or other Instrument constituting Collateral, except as provided in Section 4.4;

(e) not create any tangible Chattel Paper without placing a legend on such tangible Chattel Paper reasonably acceptable to the Collateral Agent indicating that the Collateral Agent has a security interest in such Chattel Paper;

(f) furnish to the Collateral Agent, from time to time at the Collateral Agent’s request, statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as the Collateral Agent may reasonably request, all in reasonable detail; and

-27-

(g) do all things reasonably requested by a Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) in accordance with this Security Agreement in order to enable such Senior Collateral Agent (or, after the Discharge of Senior Obligations, the Collateral Agent) to have and maintain control over the Collateral consisting of Investment Property, Deposit Accounts, Letter-of-Credit-Rights and Electronic Chattel Paper.

Each Grantor agrees that a carbon, photographic or other reproduction of this Security Agreement or any UCC financing statement covering the Collateral or any part thereof shall be sufficient as a UCC financing statement where permitted by law. Each Grantor hereby authorizes the Collateral Agent to file financing statements describing as the collateral covered thereby “all of the debtor’s personal property or assets”, “all assets” or words to that effect, notwithstanding that such wording may be broader in scope than the Collateral described in this Security Agreement.

SECTION 4.13. Insurance. Each Grantor will maintain with financially sound and reputable insurance companies such insurance in such amounts and against such risks as may be customary in the case of reputable Persons of similar size engaged in the same or similar lines of business, including without limitation property insurance with respect to all tangible Collateral and comprehensive general public liability insurance, or will self-insure to the extent customary for reputable Persons of similar size engaged in the same or similar lines of business. Each such policy of insurance shall contain the insurer’s promise not to cancel the policy or allow the policy to lapse without renewal without 30 days’ prior written notice to the Collateral Agent and shall name the Collateral Agent as an additional insured or (subject to the rights and interest of the holders of any Senior Obligations) lender loss payee, as appropriate, as its interests may appear. Each Grantor will promptly notify the Collateral Agent of any loss or material damage to any material part of the Collateral.

ARTICLE V

THE COLLATERAL AGENT

SECTION 5.1. Collateral Agent Appointed Attorney-in-Fact. Each Grantor hereby irrevocably appoints the Collateral Agent its attorney-in-fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to time in the Collateral Agent’s discretion, following the occurrence and during the continuance of an Event of Default, to take any action and to execute any instrument which the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Security Agreement, including (a) to ask, demand, collect, xxx for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral, (b) to receive, endorse, and collect any drafts or other Instruments, Documents and Chattel Paper, in connection with clause (a) above, (c) to file any claims or take any action or institute any proceedings which the Collateral Agent may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Collateral Agent with respect to any of the Collateral,

-28-

and (d) to perform the affirmative obligations of such Grantor hereunder. EACH GRANTOR HEREBY ACKNOWLEDGES, CONSENTS AND AGREES THAT THE POWER OF ATTORNEY GRANTED PURSUANT TO THIS SECTION 5.1 IS IRREVOCABLE AND COUPLED WITH AN INTEREST AND SHALL BE EFFECTIVE UNTIL THE TERMINATION DATE.

SECTION 5.2. Collateral Agent May Perform. If any Grantor fails to perform any agreement contained herein, the Collateral Agent may itself perform, or cause performance of, such agreement, and the expenses of the Collateral Agent incurred in connection therewith shall be payable by such Grantor pursuant to Section 6.4 hereof and the Collateral Agent may from time to time take any other action which the Collateral Agent reasonably deems necessary for the maintenance, preservation or protection of any of the Collateral or of its security interest therein.

SECTION 5.3. Collateral Agent Has No Duty. The powers conferred on the Collateral Agent hereunder are solely to protect its interest (on behalf of the Secured Parties) in the Collateral and shall not impose any duty on it to exercise any such powers. Except for reasonable care of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Collateral or responsibility for (a) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Investment Property and any other Pledged Property, whether or not the Collateral Agent has or is deemed to have knowledge of such matters, or (b) taking any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral.

SECTION 5.4. Reasonable Care. The Collateral Agent is required to exercise reasonable care in the custody and preservation of any of the Collateral in its possession; provided, that the Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of any of the Collateral (a) if such Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own personal property, or (b) if the Collateral Agent takes such action for that purpose as any Grantor reasonably requests in writing at times other than upon the occurrence and during the continuance of an Event of Default; provided, further, that failure of the Collateral Agent to comply with any such request at any time shall not in itself be deemed a failure to exercise reasonable care.

ARTICLE VI

REMEDIES

SECTION 6.1. Certain Remedies. If any Event of Default shall have occurred and be continuing:

(a) The Collateral Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party on default under the UCC (whether or not the UCC applies to the affected Collateral) and also may (i) take possession of any Collateral not already in its possession without demand and without legal process, (ii) require any Grantor to, and each Grantor hereby 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 to be designated

-29-

by the Collateral Agent that is reasonably convenient to both parties, (iii) subject to applicable law or agreements with landlords, enter onto the property where any Collateral is located and take possession thereof without demand and without legal process, (iv) without notice except as specified below, lease, license, sell or otherwise dispose of the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Collateral Agent may deem commercially reasonable. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten (10) days’ prior notice to the applicable Grantor of the time and place of any public sale or the time of any private sale is to be made shall constitute reasonable notification; provided, however, that with respect to Collateral that is (x) perishable or threatens to decline speedily in value, or (y) is of a type customarily sold on a recognized market (including but not limited to, Investment Property), no notice of sale or disposition need be given. For purposes of this Article VI, notice of any intended sale or disposition of any Collateral may be given by first-class mail, hand-delivery (through a delivery service or otherwise), facsimile or email, and shall be deemed to have been “sent” upon deposit in the U.S. Mails with adequate postage properly affixed, upon delivery to an express delivery service or upon electronic submission through telephonic or internet services, as applicable. The Collateral Agent shall not be obligated to make any sale of Collateral 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.

(b) Each Grantor agrees and acknowledges that a commercially reasonable disposition of Inventory, Equipment, Goods, Computer Hardware and Software Collateral, or Intellectual Property may be by lease or license of, in addition to the sale of, such Collateral. Each Grantor further agrees and acknowledges that each of the following shall be deemed a reasonable commercial disposition: (i) a disposition made in the usual manner on any recognized market, (ii) a disposition at the price current in any recognized market at the time of disposition, and (iii) a disposition in conformity with reasonable commercial practices among dealers in the type of property subject to the disposition.

(c) All cash Proceeds received by the Collateral Agent in respect of any sale of, collection from, or other realization upon, all or any part of the Collateral shall be, subject to the rights and interests of the holders of any Senior Obligations, applied by the Collateral Agent against all or any part of the Secured Obligations as set forth in the Indenture. The Collateral Agent shall not be obligated to apply or pay over for application noncash proceeds of collection or enforcement unless (i) the failure to do so would be commercially unreasonable, and (ii) the affected party has provided the Collateral Agent with a written demand to apply or pay over such noncash proceeds on such basis.

(d) The Collateral Agent may do any or all of the following: (i) transfer all or any part of the Collateral into the name of the Collateral Agent or its nominee, with or without disclosing that such Collateral is subject to the Lien hereunder, (ii) notify the

-30-

parties obligated on any of the Collateral to make payment to the Collateral Agent of any amount due or to become due thereunder, (iii) withdraw, or cause or direct the withdrawal, of all funds with respect to any Collateral Account or any other Deposit Account subject to an Account Control Agreement, (iv) enforce collection of any of the Collateral by suit or otherwise, and surrender, release or exchange all or any part thereof, or compromise or extend or renew for any period (whether or not longer than the original period) any obligations of any nature of any party with respect thereto, (v) endorse any checks, drafts, or other writings in the applicable Grantor’s name to allow collection of the Collateral, (vi) take control of any Proceeds of the Collateral, or (vii) execute (in the name, place and stead of the applicable Grantor) endorsements, assignments, stock powers and other instruments of conveyance or transfer with respect to all or any of the Collateral.

SECTION 6.2. Securities Laws. If the Collateral Agent shall determine to exercise its right to sell all or any of the Collateral that are Equity Interests pursuant to Section 6.1, each Grantor agrees that, upon request of the Collateral Agent, such Grantor will, at its own expense:

(a) execute and deliver, and cause (or, with respect to any issuer which is not a Subsidiary of such Grantor, use its reasonable efforts to cause) each Pledged Interests Issuer or other issuer of the Collateral contemplated to be sold and the directors and officers thereof to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts and things, as may be necessary or, in the reasonable opinion of the Collateral Agent, advisable to register such Collateral under the provisions of the Securities Act of 1933, as from time to time amended (the “Securities Act”), and cause the registration statement relating thereto to become effective and to remain effective for such period as prospectuses are required by law to be furnished, and to make all amendments and supplements thereto and to the related prospectus which, in the reasonable opinion of the Collateral Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the SEC applicable thereto;

(b) use its reasonable efforts to exempt the Collateral under the state securities or “Blue Sky” laws and to obtain all necessary Governmental Approvals for the sale of the Collateral, as requested by the Collateral Agent;

(c) cause (or, with respect to any issuer that is not a Subsidiary of such Grantor, use its reasonable efforts to cause) each such Pledged Interests Issuer or other issuer to make available to its security holders, as soon as practicable, an earnings statement that will satisfy the provisions of Section 11(a) of the Securities Act; and

(d) do or cause to be done all such other acts and things as may be reasonably necessary to make such sale of the Collateral or any part thereof valid and binding and in compliance with applicable law.

Each Grantor acknowledges the impossibility of ascertaining the amount of damages that would be suffered by the Collateral Agent or the Secured Parties by reason of the failure by such Grantor to perform any of the covenants contained in this Section and consequently agrees that, if such Grantor shall fail to perform any of such covenants, it shall pay, as liquidated damages

-31-

and not as a penalty, an amount equal to the value (as reasonably determined by the Collateral Agent in good faith) of such Collateral on the date the Collateral Agent shall demand compliance with this Section 6.2.

SECTION 6.3. Compliance with Restrictions. Each Grantor agrees that in any sale of any of the Collateral whenever an Event of Default shall have occurred and be continuing, the Collateral Agent is hereby authorized to comply with any limitation or restriction in connection with such sale as it may be advised by counsel is necessary in order to avoid any violation of applicable law (including compliance with such procedures as may restrict the number of prospective bidders and purchasers, require that such prospective bidders and purchasers have certain qualifications, and restrict such prospective bidders and purchasers to Persons who will represent and agree that they are purchasing for their own account for investment and not with a view to the distribution or resale of such Collateral), or in order to obtain any required approval of the sale or of the purchaser by any Governmental Authority or official, and each Grantor further agrees that such compliance shall not result in such sale being considered or deemed not to have been made in a commercially reasonable manner, nor shall the Collateral Agent be liable nor accountable to such Grantor for any discount allowed by the reason of the fact that such Collateral is sold in compliance with any such limitation or restriction.

SECTION 6.4. Indemnity and Expenses.

(a) Each Grantor hereby indemnifies and holds harmless the Collateral Agent, each Secured Party and each of their respective officers, directors, employees and agents (the “Indemnified Parties”) from and against any and all claims, losses and liabilities arising out of or resulting from this Security Agreement or any other Indenture Document (including, without limitation, enforcement of this Security Agreement), except claims, losses or liabilities resulting from such Indemnified Party’s gross negligence, willful misconduct or unlawful acts; PROVIDED, HOWEVER, THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT EACH INDEMNIFIED PARTY BE INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER THAN GROSS NEGLIGENCE), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL. If and to the extent that the foregoing undertaking may be unenforceable for any reason, each Grantor hereby agrees to make the maximum contribution to the payment and satisfaction of each of the foregoing which is permissible under applicable law.

(b) Other than as set forth in clause (c) below, each Grantor will upon demand pay to the Collateral Agent and any counsel the amount of any and all expenses, including the reasonable fees and disbursements of its counsel and of any experts and agents, which the Collateral Agent and any counsel may incur in connection herewith, including without limitation in connection with the administration of this Security Agreement and the custody, preservation, use or operation of, any of the Collateral.

(c) Each Grantor will upon demand pay to the Collateral Agent and any counsel the amount of any and all expenses, including the fees and disbursements of its counsel and of any experts and agents, which the Collateral Agent and any counsel may incur in connection with (i) the sale of, collection from, or other realization upon, any of

-32-

the Collateral, (ii) the exercise or enforcement of any of the rights of the Collateral Agent or any of the Secured Parties hereunder, or (iii) the failure by any Grantor to perform or observe any of the provisions hereof.

SECTION 6.5. Warranties. The Collateral Agent may sell the Collateral without giving any warranties or representations as to the Collateral. The Collateral Agent may disclaim any warranties of title or the like. Each Grantor agrees that this procedure will not be considered to adversely affect the commercial reasonableness of any sale of the Collateral.

SECTION 8.9. Counterparts. This Security Agreement may be executed by the parties hereto in several counterparts, each of which shall be deemed to be an original and all of which shall constitute together but one and the same agreement.

SECTION 8.12. Waiver of Jury Trial. EACH GRANTOR HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW ANY RIGHTS IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, EACH INDENTURE DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE COLLATERAL AGENT, ANY OTHER SECURED PARTY OR ANY OBLIGOR IN CONNECTION THEREWITH.

A. Reference is made to that certain Indenture dated as of March 31, 2010 among the Company, as Issuer, each of the subsidiaries of the Company party thereto, as Guarantors (the “Guarantors”), and U.S. Bank National Association, as Trustee (in such capacity, the “Trustee”), as amended and supplemented by the First Supplemental Indenture dated March 31, 2010 among the Company, as Issuer, the Guarantors, and the Trustee (as so amended and supplemented, and as further amended, restated, supplemented or otherwise modified from time to time, the “Indenture”).

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

C. Section 8.11 of the Security Agreement provides that additional Subsidiaries of the Company may become Grantors under the Security Agreement by execution and delivery of an instrument in the form of this Supplement. The undersigned Subsidiary of the Company (the “New Grantor”) is executing this Supplement in accordance with the requirements of the Indenture to become a Grantor under the Security Agreement.

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

SECTION 1. In accordance with Section 8.11 of the Security Agreement, the New Grantor 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 Grantor hereby agrees (a) 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 Grantor, as security for the payment and performance in full of the Secured Obligations (as defined in the Security Agreement), does hereby create and grant to the Collateral Agent, its successors and assigns, for the benefit of the Secured Parties, their successors and assigns as provided in the Security Agreement, a continuing security interest in and lien on all of the New Grantor’s right, title and interest in and to the Collateral (as defined in the Security Agreement) of the New Grantor. Each reference to a “Grantor” in the Security Agreement shall be deemed to include the New Grantor. The Security Agreement is hereby incorporated herein by reference.

SECTION 2. The New Grantor 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 (subject to applicable bankruptcy, reorganization, insolvency, moratorium or similar laws affecting creditors’ rights generally and subject, as to enforceability, to equitable principles of general application (regardless of whether enforcement is sought in a proceeding in equity or at law)).

SECTION 3. This Supplement may be executed in 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 counterparts of this Supplement that, when taken together, bear the signatures of the New Grantor and the Collateral Agent. 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 Grantor hereby agrees that the schedules attached to the Security Agreement are hereby supplemented by the corresponding schedules attached to this Supplement. The New Grantor hereby represents and warrants that the information provided in the schedules attached hereto are true and correct as of the date hereof.

SECTION 5. The New Grantor hereby expressly acknowledges and agrees to the terms of Section 6.4. (Indemnity and Expenses) of the Security Agreement and expressly acknowledges the irrevocable proxy provided in Section 4.1(e) of the Security Agreement. In furtherance thereof, NEW GRANTOR HEREBY GRANTS THE COLLATERAL AGENT AN IRREVOCABLE PROXY (WHICH IRREVOCABLE PROXY SHALL CONTINUE IN EFFECT UNTIL THE TERMINATION DATE) EXERCISABLE UNDER THE CIRCUMSTANCES PROVIDED IN SECTION 4.1 OF THE SECURITY AGREEMENT, TO VOTE THE PLEDGED SHARES, PLEDGED INTERESTS, INVESTMENT PROPERTY AND SUCH OTHER COLLATERAL.

SECTION 6. Except as expressly supplemented hereby, the Security Agreement shall remain in full force and effect.

SECTION 7.

SECTION 8. In case any one or more of the provisions contained in this Supplement should be held invalid, illegal or unenforceable in any respect, neither party hereto shall be required to comply with such provision for so long as such provision is held to be invalid, illegal or unenforceable, but 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.

Annex I to Junior Lien Pledge and Security Agreement

SECTION 10. The New Grantor 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.

SECTION 11. NEW GRANTOR HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW ANY RIGHTS IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, EACH INDENTURE DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE COLLATERAL AGENT OR ANY OTHER SECURED PARTY OR ANY GRANTOR IN CONNECTION THEREWITH. NEW GRANTOR ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER INDENTURE DOCUMENT TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE COLLATERAL AGENT, THE TRUSTEE AND EACH EXCHANGING NOTEHOLDER ENTERING INTO THE INDENTURE DOCUMENTS.
