The name set forth on the signature page is the true and correct name of the Debtor.

3.2. Ownership, No Liens, etc. The Debtor owns the Collateral free and clear of any Lien, except for the security interest created by this Agreement and Permitted Liens. No effective financing statement, evidence of transfer of ownership or other filing similar in effect covering any of the Collateral is on file in any recording office, except those filed in favor of the Collateral Agent and the Secured Party relating to this Agreement.

3.3. Validity, etc. This Agreement creates a valid security interest in the Collateral securing the payment of the Obligations. The Debtor has filed or caused to be filed all financing statements in the appropriate offices therefor (or has delivered to the Collateral Agent such financing statements in form suitable for filing in such offices) and has taken all of the actions necessary to perfect the security interests in the Collateral. The filing office where financing statements need to be filed in order to perfect the Collateral Agent’s Lien on the Collateral is set forth in Schedule I hereto.

3.4. No Consents. No consent, approval, authorization, or order of, or filing (other than the filing of the financing statements in the filing office listed in Schedule I hereto) registration or qualification with, any Governmental Authority is required either

(a) for the grant by the Debtor of the security interest granted hereby or the pledge by the Debtor of any Collateral pursuant hereto;

(b) for the perfection of the security interest created by this Agreement or the exercise by the Collateral Agent of its rights and remedies hereunder; or

(c) for the exercise by the Collateral Agent of the voting or other rights provided for in this Agreement, or, except as may be required in connection with a disposition of the Collateral by laws affecting the offering and sale of securities generally, the remedies in respect of the Collateral pursuant to this Agreement.

3.5. Inventory. All Inventory is, and will be, of good and merchantable quality, free from any material defects. Such Inventory is not, and will not be, subject to any licensing, patent, trademark, trade name or copyright agreement with any Person that restricts the Debtor’s or Collateral Agent’s ability to manufacture and/or sell the Inventory. The completion and manufacturing process of such Inventory by a Person other than the Debtor would be permitted under any contract to which the Debtor is a party or to which the Inventory is subject. The Debtor does not sell any Inventory to any customer on approval or on any other basis that entitles the customer to return, or which may obligate the Debtor to repurchase, such Inventory. None of the Debtor’s Inventory has been, or will be, produced in violation of any provision of the Fair Labor Standards Act of 1938, or in violation of any other law.

The Debtor covenants and agrees that, until the indefeasible payment in full of all Obligations, the Debtor will perform, comply with and be bound by the obligations set forth below.

4.1. Continuous Pledge. The Debtor will deliver to the Collateral Agent and at all times keep pledged to the Collateral Agent pursuant hereto, on a first-priority, perfected basis, all Collateral, and all proceeds and rights from time to time received by or distributable to the Debtor in respect thereof, subject to any Permitted Liens, any Liens securing the Senior Indebtedness (as defined in the Notes) and subject to the Intercreditor Agreement (as defined in the Purchase Agreement) at such time as it exists.

4.2. No Liens or Restrictions on Transfer or Change of Control. Subject to Section 4.1, all Collateral shall be free and clear of any Liens (other than Permitted Liens) and restrictions on the transfer thereof, including contractual provisions which prohibit the assignment of rights under contracts. Without limiting the generality of the foregoing, the Company will use commercially reasonable efforts to exclude from agreements, instruments, deeds or leases to which it becomes a party after the date hereof provisions that would prevent the Company from creating a security interest in such agreement, instrument, deed or lease or any rights or property acquired thereunder as contemplated hereby. Except with the written consent of the Secured Party, the Company will use commercially reasonable efforts to exclude from any agreement, instrument, deed or lease provisions that would restrict the change of control or ownership of the Company, or the creation of a security interest in the ownership of the Company.

6

4.3. Voting Rights: Dividends, etc. Until the indefeasible payment in full of all Obligations, the Debtor agrees:

(a) immediately upon the occurrence and continuance of a Specified Event of Default and so long as the Collateral Agent has notified the Debtor of the Collateral Agent’s intention to exercise its voting power under this clause, that the Collateral Agent may exercise (to the exclusion of the Debtor) the voting power and all other incidental rights of ownership with respect to any Collateral and the Debtor hereby grants the Collateral Agent an irrevocable proxy, exercisable under such circumstances, to vote all rights associated with the Collateral; and

(b) to promptly deliver to the Collateral Agent such additional proxies and other documents as may be necessary to allow the Collateral Agent to exercise such voting power.

The Debtor hereby authorizes the Collateral Agent to endorse, in the name of the Collateral Agent, any item, howsoever received by the Collateral Agent, representing any payment on or other proceeds of any Collateral. All payment intangibles and proceeds which may at any time and from time to time be held by the Debtor but which the Debtor is then obligated to deliver to the Collateral Agent, shall, until delivery to the Collateral Agent, be held by the Debtor separate and apart from its other property in trust for the Collateral Agent. The Collateral Agent agrees that unless a Specified Event of Default shall have occurred and be continuing and the Collateral Agent shall have given the notice referred to in clause (a), the Debtor will have the exclusive voting power with respect to the Collateral and the Collateral Agent will, upon the written request of the Debtor, promptly deliver such proxies and other documents, if any, as shall be reasonably requested by the Debtor which are necessary to allow the Debtor to exercise that voting power; provided, that the Debtor agrees that no vote shall be cast, or consent, waiver, or ratification given, or action taken by the Debtor that would impair any Collateral or be inconsistent with or violate any provision of the Notes.

4.4. Change of Name, etc. The Debtor will not change its name or place of incorporation or organization except upon 30 days’ prior written notice to the Collateral Agent. In addition, the Debtor shall supplement the information contained in Schedule I hereto upon any such change including any changes to the information set forth in Section 3.1.

4.5. Further Assurances, etc. The Debtor 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 request, in order to perfect, preserve and protect any security interest granted or purported to be granted hereby or to enable the Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Without limiting the generality of the foregoing, the Debtor will:

(a) from time to time upon the request of the Collateral Agent after the occurrence and during the continuance of any Specified Event of Default promptly transfer any securities constituting Collateral into the name of the Collateral Agent (or any nominee designated by the Collateral Agent);

7

(b) execute and file (or cause to be filed) such financing statements or continuation statements, or amendments thereto, and such other instruments or notices, as may be necessary or that the Collateral Agent may reasonably request in order to perfect and preserve the security interests and other rights granted or purported to be granted to the Collateral Agent hereby;

(c) not take or omit to take any action the taking or the omission of which would result in any impairment or alteration of the rights of the Debtor in respect of the Collateral; and

(d) 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.

The Debtor hereby authorizes the Collateral Agent to file (without the signature of the Debtor) one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral. The Debtor agrees that an electronic copy or a carbon, photographic or other reproduction of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement.

6.3. Indemnity and Expenses.
