Without limiting the generality of the foregoing, each Subsidiary Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by any other Grantor to the Collateral Agent or any Investor under or in respect of the Secured Transaction Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such other Grantor.

(ii) Each Subsidiary Guarantor, and by its acceptance of this Subsidiary Guaranty, the Collateral Agent and each other Investor, hereby confirms that it is the intention of all such Persons that this Subsidiary Guaranty and the Obligations of each Subsidiary Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Subsidiary Guaranty and the Obligations of each Subsidiary Guarantor hereunder. To effectuate the foregoing intention, the Collateral Agent, the other Investors and the Subsidiary Guarantors hereby irrevocably agree that the Guaranteed Obligations of each Subsidiary Guarantor under this Subsidiary Guaranty at any time shall be limited to the maximum amount as will result in the Guaranteed Obligations of such Subsidiary Guarantor under this Subsidiary Guaranty not constituting a fraudulent transfer or conveyance.

(iii) Each Subsidiary Guarantor hereby unconditionally and irrevocably agrees that in the event any payment shall be required to be made to the Collateral Agent or any Investor under this Subsidiary Guaranty or any other guaranty, such Subsidiary Guarantor will contribute, to the maximum extent permitted by law, such amounts to each other Subsidiary Guarantor and each other guarantor so as to maximize the aggregate amount paid to the Collateral Agent and Investors under or in respect of the Secured Transaction Documents.

(b) Subsidiary Guaranty Absolute. Each U.S. Subsidiary Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Secured Transaction Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Collateral Agent or any Investor with respect thereto. The Obligations of each Subsidiary Guarantor under or in respect of this Subsidiary Guaranty are independent of the Guaranteed Obligations or any other Obligations of any other Grantor under or in respect of the Secured Transaction Documents, and a separate action or actions may be brought and prosecuted against each Subsidiary Guarantor to enforce this Subsidiary Guaranty, irrespective of whether any action is brought against the Company or any other Grantor or whether the Company or any other Grantor is joined in any such action or actions. The liability of each Subsidiary Guarantor under this Subsidiary Guaranty shall be irrevocable, absolute and unconditional irrespective of, and each Subsidiary Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to, any or all of the following:

(i) any lack of validity or enforceability of any Secured Transaction Document or any agreement or instrument relating thereto;

(ii) any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations or any other Obligations of any other Grantor under or in respect of the Secured Transaction Documents, or any other amendment or waiver of or any consent to departure from any Secured Transaction Document, including, without limitation, any increase in the Guaranteed Obligations resulting from the extension of additional credit to any Grantor or any of its Subsidiaries or otherwise;

This Subsidiary Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by any Investor or any other Person upon the insolvency, bankruptcy or reorganization of the Company or any other Grantor or otherwise, all as though such payment had not been made.

Each Subsidiary Guarantor hereby unconditionally and irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Company, any other Grantor or any other insider guarantor that arise from the existence, payment, performance or enforcement of such Subsidiary Guarantor’s obligations under or in respect of this Subsidiary Guaranty or any other Secured Transaction Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of any Investor against the Company, any other Grantor or any other insider guarantor, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Company, any other Grantor or any other insider guarantor, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Guaranteed Obligations (other than contingent indemnification obligations) and all other amounts payable under this Subsidiary Guaranty shall have been paid in full in cash.

(e) Subordination. Each Subsidiary Guarantor hereby subordinates any and all debts, liabilities and other Obligations owed to such Subsidiary Guarantor by each other Grantor (the “Subordinated Obligations”) to the Guaranteed Obligations to the extent and in the manner hereinafter set forth in this Section 1.3:

(i) Prohibited Payments, Etc. Except during the continuance of an Event of Default, each Subsidiary Guarantor may receive payments from any other Grantor on account of the Subordinated Obligations.

In any proceeding under any Bankruptcy Law relating to any other Grantor, each Subsidiary Guarantor agrees that the Investors shall be entitled to receive payment in full in cash of all Guaranteed Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Bankruptcy Law, whether or not constituting an allowed claim in such proceeding (“Post-Petition Interest”)) (other than contingent indemnification obligations) before such Subsidiary Guarantor receives payment of any Subordinated Obligations.

(iii) Turn-Over. After the occurrence and during the continuance of any Event of Default, each Subsidiary Guarantor shall, if the Collateral Agent so requests, collect, enforce and

receive payments on account of the Subordinated Obligations as trustee for the Investors and deliver such payments to the Collateral Agent on account of the Guaranteed Obligations (including all Post-Petition Interest), together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of such Subsidiary Guarantor under the other provisions of this Subsidiary Guaranty.

(iv) Collateral Agent Authorization. After the occurrence and during the continuance of any Event of Default, the Collateral Agent is authorized and empowered (but without any obligation to so do), in its reasonable discretion, (A) in the name of each Subsidiary Guarantor, to collect and enforce, and to submit claims in respect of, the Subordinated Obligations and to apply any amounts received thereon to the Guaranteed Obligations (including any and all Post-Petition Interest), and (B) to require each Subsidiary Guarantor (1) to collect and enforce, and to submit claims in respect of, the Subordinated Obligations and (2) to pay any amounts received on such obligations to the Collateral Agent for application to the Guaranteed Obligations (including any and all Post-Petition Interest).

(f) Continuing Subsidiary Guaranty; Assignments. This Subsidiary Guaranty is a continuing guaranty and shall (i) remain in full force and effect until the payment in full in cash of the Guaranteed Obligations and all other amounts payable under this Subsidiary Guaranty, (ii) be binding upon each Subsidiary Guarantor, its successors and assigns, and (iii) inure to the benefit of and be enforceable by the Investors and their successors, transferees and assigns.

Section 1.4 Grant of Security

(a) Grant by U.S. Grantors. As security for the payment or performance, as applicable, in full of the Obligations, each U.S. Grantor hereby pledges and grants to the Collateral Agent, for the ratable benefit of the Secured Parties, a lien on and security interest (the “U.S. Security Interest”) in and to all of the right, title and interest of such U.S. Grantor in, to and under the following property, wherever located, whether now existing or hereafter arising or acquired from time to time (all of which being hereinafter collectively referred to as the “U.S. Collateral”):

As security for the payment or performance, as applicable, in full of the Obligations, each Israeli Grantor hereby pledges and grants to the Collateral Agent, for the ratable benefit of the Secured Parties, a lien on and security interest (the “Israeli Security Interest”, together with the U.S. Security Interest, the “Security Interest”) in and to all of the right, title and interest of such Israeli Grantor in, to and under the “Collateral” (as that term is defined in the Pledge Agreements each attached substantially in the form of Exhibits D and Exhibit E hereto, respectively, to be executed and delivered to the Collateral Agent concurrently with this Guaranty and Security Agreement), wherever located (all of which being hereinafter collectively referred to as the “Israeli Collateral” and together with the U.S. Collateral, the “Collateral”).

(c) Revisions to UCC. For the avoidance of doubt, it is expressly understood and agreed that, to the extent the UCC is revised after the date hereof such that the definition of any of the foregoing terms included in the description or definition of the Collateral is changed, the parties hereto desire that any property which is included in such changed definitions, but which would not otherwise be included in the Security Interest on the date hereof, nevertheless be included in the Security Interest upon the effective date of such revision. Notwithstanding the immediately preceding sentence, the Security Interest is intended to apply immediately on the date hereof to all of the Collateral to the fullest extent permitted by applicable law, regardless of whether any particular item of the Collateral was then subject to the UCC.

(A) Upon the direction of the Collateral Agent, all rights of each U.S. Grantor to dividends, interest or principal that it is authorized to receive pursuant to subsection (c)(i)(C) shall cease, and all such rights shall thereupon become vested in the Collateral Agent, which shall have the sole and exclusive right and authority to receive and retain such dividends, interest or principal, as applicable. All dividends, interest and principal received by or on behalf of any U.S. Grantor contrary to the provisions of this Section shall be held in trust for the benefit of the Collateral Agent, shall be segregated from other property or funds of such U.S. Grantor and shall be forthwith delivered to the Collateral Agent upon demand in the same form as so received (with any necessary endorsement). Any and all money and other property paid over to or received by the Collateral Agent pursuant to the provisions of this subsection (c)(ii)(A) shall be retained by the Collateral Agent in an account to be established in the name of the Collateral Agent, for the ratable benefit of the Secured Parties, upon receipt of such money or other property and shall be applied in accordance with the provisions of Section 6.2. Subject to the provisions of this subsection (c)(ii)(A), such account shall at all times be under the sole dominion and control of the Collateral Agent, and the Collateral Agent shall at all times have the sole right to make withdrawals therefrom and to exercise all rights with respect to the funds and other property from time to time deposited therein or credited thereto as set forth in the Secured Transaction Documents. After all Events of Default have been cured or waived, the Collateral Agent shall, within five Business Days after all such Events of Default have been cured or waived, repay to the applicable U.S. Grantor all cash dividends, interest and principal (without interest) that such U.S. Grantor would otherwise be permitted to retain pursuant to the terms of subsection (c)(i)(C) and which remain in such account.

(B) Upon the direction of the Collateral Agent, all rights of each U.S. Grantor to exercise the voting and consensual rights and powers it is entitled to exercise pursuant to subsection (c)(i)(A), and the obligations of the Collateral Agent under subsection (c)(i)(B), shall cease, and all such rights shall thereupon become vested in the Collateral Agent, which shall have the sole and exclusive right and authority to exercise such voting and consensual rights and powers, provided that, unless otherwise directed by the Required Investors, the Collateral Agent shall have the right from time to time following and during the continuance of an Event of Default to permit such U.S. Grantor to exercise such rights. After all Events of Default have been cured or waived, the applicable U.S. Grantor will have the right to exercise the voting and consensual rights and powers that it would otherwise be entitled to exercise pursuant to the terms of subsection (c)(i)(A).

(d) Covenants and Agreements. Each U.S. Grantor hereby covenants and agrees as follows:

(i) Each U.S. Grantor agrees that it will not establish or maintain, or permit any other U.S. Grantor to establish or maintain, any Securities Account or commodities account that is not a Control Account.

(ii) In the event (A) any U.S. Grantor or any Approved Securities Intermediary shall, after the date hereof, terminate an agreement with respect to the maintenance of a Control Account for any reason, (B) the Collateral Agent shall demand the termination of an agreement with respect to the maintenance of a Control Account as a result of the failure of an Approved Securities Intermediary to comply with the terms of the applicable Control Account Letter, or (C) the Collateral Agent determines in its sole discretion that the financial condition of an Approved Securities Intermediary has materially deteriorated, such U.S. Grantor agrees to promptly transfer the assets held in such Control Account to another Control Account reasonably acceptable to the Collateral Agent.

Section 3.5 Letter of Credit Rights

Each of the U.S. Grantors, jointly with the other U.S. Grantors and severally, represents and warrants to the Collateral Agent and the other Secured Parties that Schedule 3.5 sets forth, as of the Applicable Date, each letter of credit giving rise to a Letter of Credit Right included in the Collateral owned or held by or on behalf of such U.S. Grantor.

Section 3.6 Intellectual Property Collateral

(a) Representations and Warranties. Each of the Grantors, jointly with the other Grantors and severally, represents and warrants to the Collateral Agent and the other Secured Parties that Schedule 3.6 sets forth, as of the Applicable Date, all of the Patents, Patent Licenses, Trademarks, Trademark Licenses, Copyrights, Copyright Licenses, Trade Secret Licenses and Domain Names included in the Collateral owned or held by or on behalf of such Grantor.

(b) Covenants and Agreements. Each Grantor hereby covenants and agrees as follows:

(i) It will not, nor will it permit any of its licensees (or sublicensees) to, do any act, or omit to do any act, whereby any Patent that is related to the conduct of its business may become invalidated or dedicated to the public, and it shall continue to mark any products covered by a Patent with the relevant patent number as necessary and sufficient to establish and preserve its maximum rights under applicable patent laws.

(ii) It will (either directly or through its licensees or its sublicensees), for each Trademark that is necessary for the conduct of its business, (A) maintain such Trademark in full force free from any claim of abandonment or invalidity for non use, (B) maintain the quality of products and services offered under such Trademark, (C) display such Trademark with notice of Federal or other analogous registration to the extent necessary and sufficient to establish and preserve its rights under applicable law, and (D) not knowingly use or knowingly permit the use of such Trademark in violation of any third party’s valid and legal rights.

(iii) It will (either directly or through its licensees or its sublicensees), for each work covered by a Copyright that is related to the conduct of its business, continue to publish, reproduce, display, adopt and distribute the work with appropriate copyright notice as necessary and sufficient to establish and preserve its maximum rights under applicable copyright laws.

(iv) It will promptly notify the Collateral Agent in writing if it knows or has reason to know that any Intellectual Property material to the conduct of its business may become abandoned, lost or dedicated to the public, or of any adverse determination or development (including the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office or the United States Copyright Office, or any similar offices or tribunals in the United States or any other country) regarding such Grantor’s ownership of any such Intellectual Property, its right to register the same, or to keep and maintain the same.

(v) In no event shall it, either directly or through any agent, employee, licensee or designee, file an application for any Intellectual Property with the United States Patent and Trademark Office, the United States Copyright Office or any similar offices in the United States or any other country, unless it promptly notifies the Collateral Agent in writing thereof and, upon request of the Collateral Agent, executes and delivers any and all agreements, instruments, documents and papers as the Collateral Agent may request to evidence the Collateral Agent’s security interest in such Intellectual

Property, and such Grantor hereby appoints the Collateral Agent as its attorney in fact to execute and file such writings for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed; such power, being coupled with an interest, is irrevocable.

(vi) It will take all necessary steps that are consistent with the practice in any proceeding before the United States Patent and Trademark Office, the United States Copyright Office or any similar offices or tribunals in the United States, Israel and the European Union, and except as otherwise determined in its good faith business judgment, any other country, to maintain and pursue each material application relating to the Intellectual Property owned or held by it or on its behalf (and to obtain the relevant grant or registration) and to maintain each issued Patent and each registered Trademark and Copyright that is material to the conduct of its business, including timely filings of applications for renewal, affidavits of use, affidavits of incontestability and payment of maintenance fees, and, if consistent, in good faith, with good business judgment, to initiate opposition, interference and cancellation proceedings against third parties. In the event that it has reason to believe that any Intellectual Property material to the conduct of its business has been or is about to be infringed, misappropriated or diluted by a third party, it promptly shall notify the Collateral Agent in writing and shall, if consistent with good business judgment, promptly sue for infringement, misappropriation or dilution and to recover any and all damages for such infringement, misappropriation or dilution, and take such other actions as are appropriate under the circumstances to protect such Intellectual Property.

(vii) During the continuance of an Event of Default, it shall use its best efforts to obtain all requisite consents or approvals by the licenser of each License to effect the assignment (as collateral security) of all of its right, title and interest thereunder to the Collateral Agent or its designee.

(viii) It shall take all steps reasonably necessary to protect the secrecy of all Trade Secrets relating to the products and services sold or delivered under or in connection with the Intellectual Property owned or held by or on its behalf, including entering into confidentiality agreements with employees and labeling and restricting access to secret information and documents.

(ix) It shall in accordance with its past practices continue to collect all amounts due or to become due to such Grantor under all Intellectual Property, and diligently exercise each material right it may have thereunder, in each case at its own cost and expense, and in connection with such collections and exercise, it shall, upon the occurrence and during the continuance of an Event of Default, take such action as it or the Collateral Agent may reasonably deem necessary. Notwithstanding the foregoing, the Collateral Agent shall have the right at any time after the occurrence and during the continuance of an Event of Default to notify, or require such Grantor to notify, any relevant obligors with respect to such amounts of the Collateral Agent’s security interest therein.

Section 3.7 Commercial Tort Claims

Each of the U.S. Grantors, jointly with the other U.S. Grantors and severally, represents and warrants to the Collateral Agent and the other Secured Parties that Schedule 3.7 sets forth, as of the Applicable Date, all Commercial Tort Claims made by it or on its behalf or to which it otherwise has any right, title or interest.

Upon the direction of the Collateral Agent following the occurrence or during the continuance of an Event of Default, each U.S. Grantor shall cause the financial institution where any Deposit Account is maintained to enter in to a Blocked Account Letter with respect to such Deposit Account, other than any Deposit Account where (1) the amount of cash on deposit in any such account shall not exceed $50,000 (exclusive of the amounts in accounts for unpaid payroll, payroll taxes and withholding taxes), and (2) the aggregate amount of cash on deposit in all accounts other than the Concentration Account or a Blocked Account shall not exceed $100,000 (exclusive of the amounts in accounts for unpaid payroll, payroll taxes and withholding taxes).

ARTICLE 4.

FURTHER ASSURANCES

Each Grantor hereby covenants and agrees, at its own cost and expense, to execute, acknowledge, deliver and/or cause to be duly filed all such further agreements, instruments and other documents (including favorable legal opinions in connection with any Transaction) that may be reasonably requested by the Collateral Agent, and take all such further actions, that the Collateral Agent may from time to time reasonably request to preserve, protect and perfect the Security Interest granted by it and the rights and remedies created hereby, including the payment of any fees and taxes required in connection with its execution and delivery of this Guaranty and Security Agreement, the granting by it of the Security Interest and the filing of any financing statements or other documents in connection herewith or therewith. In addition, to the extent permitted by applicable law, each Grantor hereby irrevocably authorizes the Collateral Agent to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral owned or held by it or on its behalf without the signature of such Grantor and additionally agrees that a photographic or other reproduction of this Guaranty and Security Agreement may be filed with the United States Patent and Trademark Office and/or the United States Copyright Office, as applicable. Each Grantor hereby further irrevocably authorizes the Collateral Agent to file a Record or Records, including financing statements, in all jurisdictions and with all filing offices that the Collateral Agent may determine, in its sole and absolute discretion, are necessary, advisable or prudent to perfect the Security Interest granted by it and agrees that such financing statements may describe the Collateral owned or held by it or on its behalf in the same manner as described herein or may contain an indication or description of collateral that describes such property in any other manner that the Collateral Agent may determine, in its sole and absolute discretion, is necessary, advisable or prudent to perfect the Security Interest granted by such Grantor, including describing such property as “all assets” or “all personal property.”

ARTICLE 5.

COLLATERAL AGENT APPOINTED ATTORNEY-IN-FACT

Each Grantor hereby appoints the Collateral Agent and any officer or agent thereof, as its true and lawful agent and attorney in fact for the purpose of carrying out the provisions of this Guaranty and

Security Agreement and taking any action and executing any instrument that the Collateral Agent may deem necessary or advisable to accomplish the purposes hereof, which appointment is irrevocable and coupled with an interest, and without limiting the generality of the foregoing, the Collateral Agent shall have the right, with power of substitution for such Grantor and in such Grantor’s name or otherwise, for the use and benefit of the Collateral Agent and the other Secured Parties, upon the occurrence and during the continuance of an Event of Default and at such other time or times permitted by the Secured Transaction Documents, (i) to receive, endorse, assign and/or deliver any and all notes, acceptances, checks, drafts, money orders or other evidences of payment relating to the Collateral owned or held by it or on its behalf or any part thereof; (ii) to demand, collect, receive payment of, give receipt for, and give discharges and releases of, any of such Collateral; (iii) to sign the name of such U.S. Grantor on any invoice or bill of lading relating to any of such Collateral; (iv) to send verifications of Receivables owned or held by it or on its behalf to any Account Debtor; (v) to commence and prosecute any and all suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect or otherwise realize on any of the Collateral owned or held by it or on its behalf or to enforce any rights in respect of any of such Collateral; (vi) to settle, compromise, compound, adjust or defend any actions, suits or proceedings relating to any of such Collateral; (vii) to notify, or to require such U.S. Grantor to notify, Account Debtors and other obligors to make payment directly to the Collateral Agent, and (viii) to use, sell, assign, transfer, pledge, make any agreement with respect to or otherwise deal with any of such Collateral, and to do all other acts and things necessary to carry out the purposes of this Guaranty and Security Agreement, as fully and completely as though the Collateral Agent were the absolute owner of such Collateral for all purposes; provided, however, that nothing herein contained shall be construed as requiring or obligating the Collateral Agent or any other Secured Party to make any commitment or to make any inquiry as to the nature or sufficiency of any payment received by the Collateral Agent or any other Secured Party, or to present or file any claim or notice, or to take any action with respect to any of the Collateral or the moneys due or to become due in respect thereof or any property covered thereby, and no action taken or omitted to be taken by the Collateral Agent or any other Secured Party with respect to any of the Collateral shall give rise to any defense, counterclaim or offset in favor of such Grantor or to any claim or action against the Collateral Agent or any other Secured Party. The provisions of this Article shall in no event relieve any Grantor of any of its obligations hereunder or under the other Secured Transaction Documents with respect to any of the Collateral or impose any obligation on the Collateral Agent or any other Secured Party to proceed in any particular manner with respect to any of the Collateral, or in any way limit the exercise by the Collateral Agent or any other Secured Party of any other or further right that it may have on the date of this Guaranty and Security Agreement or hereafter, whether hereunder, under any other Secured Transaction Document, by law or otherwise. Any sale pursuant to the provisions of this paragraph shall be deemed to conform to the commercially reasonable standards as provided in Part 6 of Article 9 of the UCC.

ARTICLE 6.

REMEDIES UPON DEFAULT

Section 6.1 Remedies Generally

(a) General Rights. Upon the occurrence and during the continuance of an Event of Default, each Grantor agrees to deliver each item of Collateral owned or held by it or on its behalf to the Collateral Agent on demand, and it is agreed that the Collateral Agent shall have the right to take any of or all the following actions at the same or different times to the extent permitted by law: (i) with respect to any Collateral consisting of Intellectual Property or Commercial Tort Claims, on demand, to cause the Security Interest to become an assignment, transfer and conveyance of any such Collateral by the applicable Grantors to the Collateral Agent, or, in the case of Intellectual Property, to license or sublicense, whether general, special or otherwise, and whether on an exclusive or non-exclusive basis,

any such Collateral throughout the world on such terms and conditions and in such manner as the Collateral Agent shall determine (other than in violation of any then-existing licensing arrangements to the extent that waivers cannot be obtained), and (ii) with or without legal process and with or without prior notice or demand for performance, to take possession of the Collateral owned or held by it or on its behalf and without liability for trespass to enter any premises where such Collateral may be located for the purpose of taking possession of or removing such Collateral and, generally, to exercise any and all rights afforded to a secured party under the UCC or other applicable law. Without limiting the generality of the foregoing, each Grantor agrees that the Collateral Agent shall have the right, subject to the mandatory requirements of applicable law, to sell or otherwise dispose of any of the Collateral owned or held by or on behalf of such Grantor, at public or private sale or at any broker’s board or on any securities exchange, for cash, upon credit or for future delivery as the Collateral Agent shall deem appropriate. The Collateral Agent shall be irrevocably authorized at any such sale of such Collateral constituting securities (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to Persons who will represent and agree that they are purchasing such Collateral for their own account for investment and not with a view to the distribution or sale thereof, and upon consummation of any such sale, the Collateral Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each such purchaser at any such sale shall hold the property sold absolutely, free from any claim or right on the part of the applicable Grantor, and such Grantor hereby waives (to the extent permitted by law) all rights of redemption, stay, valuation and appraisal which such Grantor now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted.

(b) Sale of Collateral. The Collateral Agent shall give each Grantor ten days’ written notice (which such Grantor agrees is reasonable notice within the meaning of Part 6 of Article 9 of the UCC) of the Collateral Agent’s intention to make any sale of any of the Collateral owned or held by or on behalf of such Grantor. Such notice, in the case of a public sale, shall state the time and place for such sale and, in the case of a sale at a broker’s board or on a securities exchange, shall state the board or exchange at which such sale is to be made and the day on which such Collateral will first be offered for sale at such board or exchange. Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as the Collateral Agent may fix and state in the notice (if any) of such sale. At any such sale, the Collateral to be sold may be sold in one lot as an entirety or in separate parcels, as the Collateral Agent may (in its sole and absolute discretion) determine. The Collateral Agent shall not be obligated to make any sale of any Collateral if it shall determine not to do so, regardless of the fact that notice of sale of such Collateral shall have been given. The Collateral Agent may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. In case any sale of any of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by the Collateral Agent until the sale price is paid by the purchaser or purchasers thereof, but the Collateral Agent shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may be sold again upon like notice. At any public (or, to the extent permitted by applicable law, private) sale made pursuant to this Section, any Secured Party may bid for or purchase, free (to the extent permitted by applicable law) from any right of redemption, stay, valuation or appraisal on the part of such Grantor (all said rights being also hereby waived and released to the extent permitted by law), any of the Collateral offered for sale and may make payment on account thereof by using any claim then due and payable to such Secured Party from such Grantor as a credit against the purchase price, and such Secured Party may, upon compliance with the terms of sale, hold, retain and dispose of such property without further accountability to such Grantor therefor. For purposes hereof, (i) a written agreement to purchase any of the Collateral shall be treated as a sale thereof, (ii) the Collateral Agent shall be free to carry out such sale pursuant to such agreement, and (iii) no Grantor shall be entitled to the return of any of the Collateral subject thereto, notwithstanding the fact that after the Collateral Agent shall have entered into such an agreement all Events of Default shall

have been remedied and the Obligations paid in full. As an alternative to exercising the power of sale herein conferred upon it, the Collateral Agent may proceed by a suit or suits at law or in equity to foreclose upon any of the Collateral and to sell any of the Collateral pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver. Without limiting the generality of the foregoing, each Grantor agrees as follows: (A) if the proceeds of any sale of the Collateral owned or held by it or on its behalf pursuant to this Article are insufficient to pay all the Obligations, it shall be liable for the resulting deficiency and the fees, charges and disbursements of any counsel employed by the Collateral Agent or any other Secured Party to collect such deficiency, (B) it hereby waives any claims against the Collateral Agent arising by reason of the fact that the price at which any such Collateral may have been sold at any private sale pursuant to this Article was less than the price that might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree, (C) there is no adequate remedy at law for failure by it to comply with the provisions of this Section and that such failure would not be adequately compensible in damages, and therefore agrees that its agreements in this Section may be specifically enforced, (D) the Collateral Agent may sell any such Collateral without giving any warranties as to such Collateral, and the Collateral Agent may specifically disclaim any warranties of title or the like, and (E) the Collateral Agent shall have no obligation to marshall any such Collateral.

Section 6.2 Application of Proceeds of Sale

The Collateral Agent shall apply the proceeds of any collection or sale of the Collateral, as well as any Collateral consisting of cash, as follows:

FIRST, to the payment of all reasonable costs and expenses incurred by the Collateral Agent in connection with such collection or sale or otherwise in connection with this Guaranty and Security Agreement, any other Secured Transaction Document or any of the Obligations, including all out of pocket court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Collateral Agent hereunder or under any other Secured Transaction Document on behalf of any Grantor and any other reasonable out-of-pocket costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Secured Transaction Document;

SECOND, to the payment in full of the Obligations (the amounts so applied to be distributed among the Secured Parties pro rata in accordance with the amounts of the Obligations owed to them on the date of any such distribution); and

THIRD, to the applicable Grantor, its successors or assigns, or as a court of competent jurisdiction may otherwise direct.

The Collateral Agent shall have sole and absolute discretion as to the time of application of any such proceeds, moneys or balances in accordance with this Guaranty and Security Agreement. Upon any sale of the Collateral by the Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the purchase money by the Collateral Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Collateral Agent or such officer or be answerable in any way for the misapplication thereof.

Section 6.3 Investment Property

In view of the position of each Grantor in relation to the Investment Property, or because of other current or future circumstances, a question may arise under the Securities Act of 1933, as now or hereafter in effect, or any similar statute hereafter enacted analogous in purpose or effect (such Act and any such similar statute as from time to time in effect being called the “Federal securities laws”) with respect to any disposition of the Investment Property permitted hereunder. Each U.S. Grantor understands that compliance with the Federal securities laws might very strictly limit the course of conduct of the Collateral Agent if the Collateral Agent were to attempt to dispose of all or any part of the Investment Property, and might also limit the extent to which or the manner in which any subsequent transferee of any Investment Property could dispose of the same. Similarly, there may be other legal restrictions or limitations affecting the Collateral Agent in any attempt to dispose of all or part of the Investment Property under applicable Blue Sky or other state securities laws or similar laws analogous in purpose or effect. Each U.S. Grantor recognizes that in light of such restrictions and limitations the Collateral Agent may, with respect to any sale of the Investment Property, limit the purchasers to those who will agree, among other things, to acquire such Investment Property for their own account, for investment, and not with a view to the distribution or resale thereof. Each U.S. Grantor acknowledges and agrees that in light of such restrictions and limitations, the Collateral Agent, in its sole and absolute discretion, (i) may proceed to make such a sale whether or not a registration statement for the purpose of registering such Investment Property, or any part thereof, shall have been filed under the Federal securities laws and (ii) may approach and negotiate with a single potential purchaser to effect such sale. Each U.S. Grantor acknowledges and agrees that any such sale might result in prices and other terms less favorable to the seller than if such sale were a public sale without such restrictions. In the event of any such sale, the Collateral Agent shall incur no responsibility or liability for selling all or any part of the Investment Property at a price that the Collateral Agent, in its discretion, may in good faith deem reasonable under the circumstances, notwithstanding the possibility that a substantially higher price might have been realized if the sale were deferred until after registration as aforesaid or if more than a single purchaser were approached. The provisions of this Section will apply notwithstanding the existence of a public or private market upon which the quotations or sales prices may exceed substantially the price at which the Collateral Agent sells any such Investment Property.

Section 6.4 Grant of License to Use Intellectual Property

For the purpose of enabling the Collateral Agent to exercise rights and remedies under this Article, at such time as the Collateral Agent shall be lawfully entitled to exercise such rights and remedies, each Grantor hereby grants to the Collateral Agent an irrevocable, non exclusive license (exercisable without payment of royalty or other compensation to such Grantor) to use, license or sub license any of the Collateral consisting of Intellectual Property now owned or held or hereafter acquired or held by or on behalf of such Grantor, and wherever the same may be located, and including in such license reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer software and programs used for the compilation or printout thereof. The use of such license by the Collateral Agent shall be exercised, at the option of the Collateral Agent, upon the occurrence and during the continuation of an Event of Default; provided that any license, sub license or other transaction entered into by the Collateral Agent in accordance herewith shall be binding upon such Grantor notwithstanding any subsequent cure of an Event of Default. Any royalties and other payments received by the Collateral Agent shall be applied in accordance with Section 6.2.

ARTICLE 7.

REIMBURSEMENT OF COLLATERAL AGENT

Each Grantor agrees, jointly with the other Grantors and severally, to pay to the Collateral Agent the amount of any and all reasonable out-of-pocket expenses, including the fees, other charges and disbursements of counsel and of any experts or agents, that the Collateral Agent may incur in connection with (i) the administration of this Guaranty and Security Agreement relating to such Grantor or any of its property, (ii) the custody or preservation of, or the sale of, collection from, or other realization upon, any of the Collateral owned or held by or on behalf of such Grantor, (iii) the exercise, enforcement or protection of any of the rights of the Collateral Agent hereunder relating to such Grantor or any of its property, or (iv) the failure by such Grantor to perform or observe any of the provisions hereof. Without limitation of its indemnification obligations under the other Secured Transaction Documents, each of the Grantors agrees, jointly with the other Grantors and severally, to indemnify the Collateral Agent and each Related Party thereof (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related out-of-pocket expenses, including reasonable counsel fees, other charges and disbursements, incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of (a) the execution or delivery by such Grantor of this Guaranty and Security Agreement or any other Secured Transaction Document or any agreement or instrument contemplated hereby or thereby, or the performance by such Grantor of its obligations under the Secured Transaction Documents and the other transactions contemplated thereby or (b) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnitee is a party thereto, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee. Any amounts payable as provided hereunder shall be additional Obligations secured hereby and by the other Secured Transaction Documents. The provisions of this Section shall remain operative and in full force and effect regardless of the termination of this Guaranty and Security Agreement or any other Secured Transaction Document, the consummation of the transactions contemplated hereby or thereby, the repayment of any of the Obligations, the invalidity or unenforceability of any term or provision of this Guaranty and Security Agreement or any other Secured Transaction Document or any investigation made by or on behalf of the Collateral Agent or any other Secured Party. All amounts due under this Section shall be payable within ten days of written demand therefor and shall bear interest at the rate of 9.50% per annum.

ARTICLE 8.

WAIVERS; AMENDMENTS

No failure or delay of the Collateral Agent in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Collateral Agent and the other Secured Parties hereunder and under the other Secured Transaction Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Guaranty and Security Agreement or any other Secured Transaction Document or consent to any departure by any Grantor therefrom shall in any event be effective unless the same shall be permitted by this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on any Grantor in any case shall entitle such Grantor to any other or further notice or demand in similar or other circumstances. Neither this Guaranty and Security Agreement nor any provision hereof may be waived, amended, supplemented or otherwise

modified, or any departure therefrom consented to, except pursuant to an agreement or agreements in writing entered into by the Grantors and Investors holding more than a majority of the aggregate principal amount of the Senior Secured Notes then outstanding, provided that no such agreement shall waive, amend, supplement or otherwise modify, or consent to a departure to, the rights or duties of the Collateral Agent hereunder without the prior written consent of the Collateral Agent.

ARTICLE 9.

SECURITY INTEREST ABSOLUTE

All rights of the Collateral Agent hereunder, the Security Interest and all obligations of each Grantor hereunder shall be absolute and unconditional irrespective of (i) any lack of validity or enforceability of the Securities Purchase Agreement, any other Secured Transaction Document, any agreement with respect to any of the Obligations, or any other agreement or instrument relating to any of the foregoing, (ii) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other waiver, amendment, supplement or other modification of, or any consent to any departure from, the Securities Purchase Agreement, any other Secured Transaction Document or any other agreement or instrument relating to any of the foregoing, (iii) any exchange, release or non-perfection of any Lien on any other collateral, or any release or waiver, amendment, supplement or other modification of, or consent under, or departure from, any guaranty, securing or guaranteeing all or any of the Obligations, or (iv) any other circumstance that might otherwise constitute a defense available to, or a discharge of, any Grantor in respect of the Obligations or in respect of this Guaranty and Security Agreement or any other Secured Transaction Document.

ARTICLE 10.

TERMINATION; RELEASE

This Guaranty and Security Agreement and the Security Interest shall terminate when the Obligations shall have been finally and indefeasibly paid in full. Upon (i) any sale, transfer or other disposition permitted by the Secured Transaction Documents (other than any sale, transfer or other disposition of any Collateral that would, immediately after giving effect thereto, continue to be Collateral but for the release of the Security Interest therein pursuant to this clause) or (ii) the effectiveness of any written consent to the release of the Security Interest in any Collateral pursuant to Article 8, the Security Interest in such Collateral shall be automatically released. In addition, if any of the Pledged Equity Interests in any Subsidiary are sold, transferred or otherwise disposed of pursuant to a transaction permitted by the Secured Transaction Documents and, immediately after giving effect thereto, such Subsidiary or subsidiary, as applicable, would no longer be a Subsidiary or a subsidiary, as applicable, then the obligations of such Subsidiary or subsidiary, as applicable, under this Guaranty and Security Agreement and the Security Interest in the Collateral owned or held by or on behalf of such Subsidiary or such subsidiary, as applicable, shall be automatically released. In connection with any termination or release pursuant to this Section, the Collateral Agent shall execute and deliver to the applicable Grantor, and hereby authorizes the filing of, at such Grantor’s cost and expense, all Uniform Commercial Code termination statements and similar documents that such Grantor may reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to this Article shall be without recourse to or warranty by the Collateral Agent or any other Secured Party.

ARTICLE 11.

ADDITIONAL SUBSIDIARY GUARANTORS AND GRANTORS

Upon execution and delivery after the date hereof by the Collateral Agent and a Subsidiary of a Supplement, such Subsidiary shall become a Subsidiary Guarantor and an Israeli Grantor or U.S. Grantor, as applicable, hereunder with the same force and effect as of the date of such execution as if originally named as a Subsidiary Guarantor and a U.S. Grantor or Israeli Grantor, as applicable, herein (each an “Additional Subsidiary Guarantor and Grantor”). The execution and delivery of any Supplement shall not require the consent of any other Grantor hereunder. The rights and obligations of each Grantor hereunder and each Grantor and other party (other than an Investor) under the Secured Transaction Documents shall remain in full force and effect notwithstanding the addition of any Additional Subsidiary Guarantor and Grantor as a party to this Guaranty and Security Agreement.

ARTICLE 12.

COLLATERAL AGENT

Each Investor hereby irrevocably appoints the Collateral Agent as its agent and authorizes the Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to the Collateral Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto.

The Person serving as the Collateral Agent hereunder shall have the same rights and powers in its capacity as an Investor as any other investor and may exercise the same as though it were not the Collateral Agent, and such Person and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Company or any Subsidiary or other Affiliate thereof as if it were not the Collateral Agent hereunder.

The Collateral Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, (i) the Collateral Agent shall not be subject to any fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing, (ii) the Collateral Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by this Agreement, and (iii) except as expressly set forth herein, the Collateral Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Company or any of the Subsidiaries that is communicated to or obtained by the Person serving as Collateral Agent or any of its Affiliates in any capacity. The Collateral Agent shall not be liable for any action taken or not taken by it in the absence of its own gross negligence or willful misconduct. The Collateral Agent shall be deemed not to have knowledge of any Event of Default unless and until written notice thereof is given to the Collateral Agent by the Company or an Investor (and, promptly after its receipt of any such notice, it shall give each Investor and the Company notice thereof), and the Collateral Agent shall not be responsible for or have any duty to ascertain or inquire into (a) any statement, warranty or representation made in or in connection with any Secured Transaction Document, (b) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (c) the performance or observance of any of the covenants, agreements or other terms or conditions set forth therein, (d) the validity, enforceability, effectiveness or genuineness thereof or any other agreement, instrument or other document or (e) the satisfaction of any condition set forth in herein, other than to confirm receipt of items expressly required to be delivered to the Collateral Agent.

The Collateral Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Collateral Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Collateral Agent may consult with legal counsel (who may be counsel for the Grantors), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Collateral Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub agents appointed by the Collateral Agent, provided that no such delegation shall serve as a release of the Collateral Agent or waiver by the Company of any rights hereunder. The Collateral Agent and any such sub agent may perform any and all its duties and exercise its rights and powers through their respective affiliates. The exculpatory provisions of the preceding paragraphs shall apply to any such sub agent and to the affiliates of the Collateral Agent and any such sub agent, and shall apply to their respective activities acting for the Collateral Agent.

Subject to the appointment and acceptance of a successor Collateral Agent as provided in this paragraph, the Collateral Agent may resign at any time by notifying the Investors and the Company. Upon any such resignation, the Investors shall have the right to appoint a successor. If no successor shall have been so appointed by the Investors and shall have accepted such appointment within 30 days after the retiring Collateral Agent gives notice of its resignation, then the retiring Collateral Agent may, on behalf of the Investors, appoint a successor Collateral Agent which shall be a bank with an office in New York, New York, or an affiliate of any such bank. Upon the acceptance of its appointment as Collateral Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent, and the retiring Collateral Agent shall be discharged from its duties and obligations hereunder. After the Collateral Agent’s resignation hereunder, the provisions of this Article shall continue in effect for the benefit of such retiring Collateral Agent, its sub agents and their respective affiliates in respect of any actions taken or omitted to be taken by any of them while it was acting as Collateral Agent.

Each Investor acknowledges that it has, independently and without reliance upon the Collateral Agent or any other Investor and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into the Secured Transaction Documents. Each Investor also acknowledges that it will, independently and without reliance upon the Collateral Agent or any other Investor and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon any Secured Transaction Document, any related agreement or any document furnished thereunder

FORM OF SUPPLEMENT

SUPPLEMENT NO. , dated as of , to the GUARANTY AND SECURITY AGREEMENT, dated as of March 22, 2006, among Vyyo Inc., a Delaware corporation (the “Company”), the subsidiaries of the Company party thereto, and Goldman, Sachs & Co., as Collateral Agent (as amended, supplemented or otherwise modified from time to time, the “Guaranty and Security Agreement”).

Reference is made to the Securities Purchase Agreement, dated as of March 18, 2006, among the Company and the investors from time to time party thereto (as amended, supplemented or otherwise modified from time to time, the “Securities Purchase Agreement”). Capitalized terms (and the term “subsidiary”) used herein and not defined herein shall have the meanings assigned to such terms in the Guaranty and Security Agreement.

The Grantors have entered into the Guaranty and Security Agreement in order to induce the Investors to enter into the Securities Purchase Agreement and purchase the Senior Secured Notes. Article 11 of the Guaranty and Security Agreement provides that additional Subsidiaries may become Subsidiary Guarantors and Grantors under the Guaranty and Security Agreement by execution and delivery of an instrument in the form of this Supplement. The undersigned Subsidiary (the “New Subsidiary Guarantor and Grantor”) is executing this Supplement in accordance with the requirements of the Senior Secured Notes to become a Subsidiary Guarantor and Grantor under the Guaranty and Security Agreement as consideration for the Senior Secured Notes previously made.

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

1. In accordance with Article 11 of the Guaranty and Security Agreement, the New Subsidiary Guarantor and Grantor by its signature below becomes a Subsidiary Guarantor and a Grantor under the Guaranty and Security Agreement with the same force and effect as if originally named therein as a Subsidiary Guarantor and a Grantor, and the New Subsidiary Guarantor and Grantor hereby agrees to all the terms and provisions of the Guaranty and Security Agreement applicable to it as a Subsidiary Guarantor and a Grantor thereunder. In furtherance of the foregoing, the New Subsidiary Guarantor and Grantor, as security for the payment and performance in full of the Obligations, does hereby create and grant to the Collateral Agent (and its successors and assigns), for the benefit of the Secured Parties (and their successors and assigns), a security interest in and lien on all of the New Subsidiary Guarantor and Grantor’s right, title and interest in and to the Collateral (as defined in the Guaranty and Security Agreement) owned or held by or on behalf of the New Subsidiary Guarantor and Grantor. Each reference to a “Subsidiary Guarantor” or to a “Grantor” in the Guaranty and Security Agreement shall be deemed to include the New Subsidiary Guarantor and Grantor. The Guaranty and Security Agreement is hereby incorporated herein by reference.

2. The New Subsidiary Guarantor and Grantor represents and warrants to the Collateral Agent and the other Secured Parties that (i) 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, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally, (ii) set forth on the Schedules attached hereto are true and complete schedules of all of the information that would have been required to have been

delivered by or on behalf of the New Subsidiary Guarantor and Grantor pursuant to the Guaranty and Security Agreement and the Schedules thereto if the New Subsidiary Guarantor and Grantor had been originally named in the Guaranty and Security Agreement, and (iii) the representations and warranties made by it as a Grantor under the Guaranty and Security Agreement are true and correct on and as of the date hereof based upon the applicable information referred to in clause (ii) of this Section.

3. This Supplement may be executed in counterparts (and by each party hereto on a different counterpart), each of which shall constitute an original, but both of which, when taken together, shall constitute but one 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 Subsidiary Guarantor and Grantor and the Collateral Agent. Delivery of an executed counterpart of this Supplement by facsimile transmission shall be as effective as delivery of a manually executed counterpart of this Supplement.

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

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

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

7. All communications and notices hereunder shall be in writing and given as provided in Article 13 of the Guaranty and Security Agreement. All communications and notices hereunder to the New Subsidiary Guarantor and Grantor shall be given to it at the address set forth in the applicable Schedule hereto, with a copy to the Company.

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

[SIGNATURE PAGE FOLLOWS]

IN WITNESS WHEREOF, the New Subsidiary Guarantor and Grantor and the Collateral Agent have duly executed this Supplement No. to the Guaranty and Security Agreement as of the day and year first above written.

Pursuant to the Guaranty and Security Agreement and related documents, the Companies have granted to the Collateral Agent, for the benefit of the Secured Parties, a security interest in certain property of the Companies consisting of all cash and all Proceeds (as such term is defined in the Guaranty and Security Agreement) received by such Companies during the term of the Guaranty and Security Agreement (collectively, the “Collateral”). Payments with respect to the Collateral shall hereafter be deposited or swept into the Accounts.

The Companies hereby transfer to the Collateral Agent exclusive control of the Accounts and all funds and other property on deposit therein.

You shall be entitled to rely and shall be fully protected in relying on the due authorization of a Blockage Notice without inquiry.

(d) From and after the effectiveness of a Blockage Notice, you will transfer (by wire transfer or other method of transfer mutually acceptable to you and the Collateral Agent) to the Collateral Agent, in same day funds, on each Banking Day, the entire balance of collected funds in the Accounts to the following account (the “Collateral Agent Concentration Account”):

In the event insufficient funds remain in the Accounts to cover such customary service charges and fees or returned, dishonored or uncollected items or payments, the Companies agree, jointly and severally, to pay and indemnify you for such amounts.

In the event that any check, draft, instrument, or other item or media of payment constituting part of the collections credited by you to the Accounts and transferred to the Collateral Agent is subsequently dishonored, returned, or otherwise not collected (“Returned Remittance”), the Collateral Agent will, upon demand of you pay to you in immediately available funds the amount of each such Returned Remittance.

This Blocked Account Letter shall be binding upon and shall inure to the benefit of you, the Companies, the Collateral Agent and the respective successors, transferees and assigns of any of the foregoing.

The Accounts shall remain subject to your contract rules and regulations for non-personal checking accounts (the “Rules and Regulations”); provided, however, that in the event of a conflict between the terms of this Blocked Account Letter and the terms of the Rules and Regulations, the terms of this Blocked Account Letter shall prevail.

You shall have no liability arising out of or relating to this Blocked Account Letter except for liability for actual damages incurred by the Companies or the Collateral Agent as a direct result of your gross negligence or willful misconduct. Without limiting the foregoing, you shall have no liability whatsoever to any person for any indirect, consequential, incidental, special or reliance damages, regardless of the form of action in which such damages are asserted (whether in contract, tort or otherwise) even if you were aware of or have been advised of the possibility of such damages.

Under no circumstances shall you be obligated to make any independent inquiry whatsoever as to the Collateral Agent’s right or authority to give you any instruction, order or direction with respect to the Accounts or the items or payments received therein, or as to the use the Collateral Agent makes of any monies deposited to the Accounts.

The Companies agree that they jointly and severally indemnify and hold you harmless from and against any and all loss, claims, damages, costs, charges, counsel fees, payments, expenses and liabilities whatsoever which you shall or may sustain or incur at any time by reason of or in consequence of (i) this Blocked Account Letter or actions or omissions in connection with this Blocked Account Letter, or (ii) your having complied with any instructions furnished by the Companies or the Collateral Agent pursuant to this Blocked Account Letter or in acting on any order or direction by the Companies or the Collateral Agent respecting the Accounts or the items and other payments received therein; provided, however, that you shall not be so indemnified for your own gross negligence or willful misconduct.

The Approved Securities Intermediary acknowledges that it has not received notice of any other security interest in the Account or the Assets. In the event any such notice is received, the Approved Securities Intermediary will promptly notify the Collateral Agent. The Pledgor herein represents that the Assets are free and clear of any Lien or encumbrances and agree that, with the
