(a) The Collateral Agent may exercise in respect of the Collateral, in addition to any other rights and remedies provided for herein or otherwise available to it, all of the rights and remedies of a secured party upon default under the Code (whether or not the Code applies to the affected Collateral), and also may, subject to the provisions of any applicable law, (i) take absolute control of the Collateral, including, without limitation, transfer into the Collateral Agent's name or into the name of its nominee or nominees (to the extent the Collateral Agent has not theretofore done so) and thereafter receive, for the benefit of the Collateral Agent and the Secured Parties, all payments made thereon, give all consents, waivers and ratifications in respect thereof and otherwise act with respect thereto as though it were the outright owner thereof, (ii) require each 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 or places to be designated by the Collateral Agent that is reasonably convenient to both parties, and the Collateral Agent may enter into and occupy any premises owned or leased by any Grantor where the Collateral or any part thereof is located or assembled for a reasonable period in order to effectuate the Collateral Agent's rights and remedies hereunder or under law, without obligation to any Grantor in respect of such occupation, and (iii) without notice except as specified below and without any obligation to prepare or process the Collateral for sale, (A) sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Agent's offices, at any exchange or broker's board or elsewhere, for cash, on credit or for future delivery, and at such price or prices and upon such other terms as the Collateral Agent may deem commercially reasonable and/or (B) lease, license or otherwise dispose of the Collateral or any part thereof upon such terms as the Collateral Agent may deem commercially reasonable. Each Grantor agrees that, to the extent notice of sale or any other disposition of the Collateral shall be required by law, at least five (5) days' prior notice to the applicable Grantor of the time and place of any public sale or the time after which any private sale or other disposition of the Collateral is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale or other disposition 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. Each Grantor hereby waives any claims against the Collateral Agent and the Buyers arising by reason of the fact that the price at which the Collateral may have been sold at a private sale was less than the price which might have been obtained at a public sale or was less than the aggregate amount of the Secured Obligations, even if the Collateral Agent accepts the first offer received and does not offer the Collateral to more than one offeree, and waives all rights that such Grantor may have to require that all or any part of the Collateral be marshaled upon any sale (public or private) thereof. Each Grantor hereby acknowledges that (i) any such sale of the Collateral by the Collateral Agent shall be made without warranty, (ii) the Collateral Agent may specifically disclaim any warranties of title, possession, quiet enjoyment or the like, (iii) the Collateral Agent may bid (which bid may be, in whole or in part, in the form of cancellation of indebtedness), if permitted by law, for the purchase, lease, license or other disposition of the Collateral or any portion thereof for the account of the Collateral Agent (on behalf of itself and the Buyers) and (iv) such actions set forth in clauses (i), (ii) and (iii) above shall not adversely affect the commercial reasonableness of any such sale of the Collateral. In addition to the foregoing, (i) upon written notice to any Grantor from the Collateral Agent, each Grantor shall cease any use of the Pledged Intellectual Property for any purpose described in such notice; (ii) the Collateral Agent may, at any time and from time to time, upon five (5) days' prior notice to any Grantor, license, whether general, special or otherwise, and whether on an exclusive or non-exclusive basis, any of the Pledged Intellectual Property, throughout the universe for such term or terms, on such conditions, and in such manner, as the Collateral Agent shall in its sole discretion determine; and (iii) the Collateral Agent may, at any time, pursuant to the authority granted in Section 6 hereof (such authority being effective upon the occurrence and during the continuance of an Event of Default), execute and deliver on behalf of a Grantor, one or more instruments of assignment of the Pledged Intellectual Property (or any application or registration thereof), in form suitable for filing, recording or registration in any country.

- 13 -

(b) Any cash held by the Collateral Agent (or its agent or designee) as Collateral and all Cash Proceeds received by the Collateral Agent (or its agent or designee) in respect of any sale of or collection from, or other realization upon, all or any part of the Collateral may, in the discretion of the Collateral Agent, be held by the Collateral Agent (or its agent or designee) as collateral for, and/or then or at any time thereafter applied (after payment of any amounts payable to the Collateral Agent pursuant to Section 8 hereof) in whole or in part by the Collateral Agent against, all or any part of the Secured Obligations in such order as the Collateral Agent shall elect, consistent with the provisions of the Transaction Documents. Any surplus of such cash or Cash Proceeds held by the Collateral Agent (or its agent or designee) and remaining after the date on which all of the Secured Obligations have been indefeasibly paid in full in cash after the termination of each of the Transaction Documents, shall be paid over to whomsoever shall be lawfully entitled to receive the same or as a court of competent jurisdiction shall direct.

(c) In the event that the proceeds of any such sale, collection or realization are insufficient to pay all amounts to which the Collateral Agent and the Buyers are legally entitled, the Grantors shall be jointly and severally liable for the deficiency, together with interest thereon at the highest rate specified in any applicable Transaction Document for interest on overdue principal thereof or such other rate as shall be fixed by applicable law, together with the costs of collection and the reasonable fees, costs, expenses and other client charges of any attorneys employed by the Collateral Agent to collect such deficiency.

(d) Each Grantor hereby acknowledges that if the Collateral Agent complies with any applicable requirements of law in connection with a disposition of the Collateral, such compliance will not adversely affect the commercial reasonableness of any sale or other disposition of the Collateral.

(e) The Collateral Agent shall not be required to marshal any present or future collateral security (including, but not limited to, this Agreement and the Collateral) for, or other assurances of payment of, the Secured Obligations or any of them or to resort to such collateral security or other assurances of payment in any particular order, and all of the Collateral Agent's rights hereunder and in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights, however existing or arising. To the extent that any Grantor lawfully may, such Grantor hereby agrees that it will not invoke any law relating to the marshalling of collateral which might cause delay in or impede the enforcement of the Collateral Agent's rights under this Agreement or under any other instrument creating or evidencing any of the Secured Obligations or under which any of the Secured Obligations is outstanding or by which any of the Secured Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, each Grantor hereby irrevocably waives the benefits of all such laws.

- 14 -

(f) Grantors irrevocably and unconditionally:

(i) consents to the appointment of pre-judgment and/or post-judgment receiver with all of the same powers that would otherwise be available to the Grantors, including, but not limited to the power to (A) hold, manage, control or dispose of the Collateral wherever located, (B) take any action with respect to the Collateral to the maximum extent permitted by law and (C) conduct a public or private sale of title and interest in and to such Collateral, including any disposition of the Collateral to the Collateral Agent/Buyers in exchange for cancellation of all or a portion of the Obligations;

(ii) consents that any such receiver can be appointed without a hearing or prior notice to the Grantors;

(iii) agrees not to oppose or otherwise interfere (directly or indirectly) with any effort by Collateral Agent to seek the appointment of a receiver to the extent that such appointment is reasonably required; and

(iv) waives any right to appeal the entry of an order authorizing the appointment of a receiver.

SECTION 8. Indemnity and Expenses.

(a) Each Grantor jointly and severally agrees to defend, protect, indemnify and hold harmless the Collateral Agent and each of the Buyers from and against any and all claims, losses, damages, liabilities, obligations, penalties, fees, reasonable costs and expenses (including, without limitation, reasonable attorneys' fees, costs, expenses and disbursements) incurred by the Collateral Agent or such Buyer to the extent that they arise out of or otherwise result from or relate to or are in connection with (i) any breach by a Grantor of a provision of this Agreement or (ii) the exercising and enforcing any of the Collateral Agent's rights in accordance with this Agreement and subject thereto. In no event shall Grantor be liable for any claims, losses or liabilities resulting from the Collateral Agent's or such Buyer's gross negligence or willful misconduct.

(b) Each Grantor jointly and severally agrees to pay to the Collateral Agent upon demand the amount of any and all costs and expenses, including the reasonable fees, costs, expenses and disbursements of counsel for the Collateral Agent and of any experts and agents (including, without limitation, any collateral trustee which may act as agent of the Collateral Agent), which the Collateral Agent may incur in connection with (i) the custody, preservation, use or operation of, or the sale of, collection from, or other realization upon, any Collateral, (ii) the exercise or enforcement of any of the rights of the Collateral Agent hereunder, or (iii) the failure by any Grantor to perform or observe any of the provisions hereof.

SECTION 10. Security Interest Absolute; Joint and Several Obligations .

(a) All rights of the Secured Parties, all Liens and all obligations of each of the Grantors hereunder shall be absolute and unconditional irrespective of (i) any change in the time, manner or place of payment of, or in any other term in respect of, all or any of the Secured Obligations, or any other amendment or waiver of or consent to any departure from the Note Purchase Agreement or any other Transaction Document, (ii) any exchange or release of, or non-perfection of any Lien on any Collateral, or any release or amendment or waiver of or consent to departure from any guaranty, for all or any of the Secured Obligations, or (iii) any other circumstance that might otherwise constitute a defense available to, or a discharge of, any of the Grantors in respect of the Secured Obligations. All authorizations and agencies contained herein with respect to any of the Collateral are irrevocable and powers coupled with an interest. Notwithstanding anything to the contrary herein, nothing in the aforesaid shall derogate from any rights and defenses granted to the Company under the Note Purchase Agreement, and in the event of any discrepancy between the provisions of this Agreement and the provisions of the Note Purchase Agreement, the provisions of the Note Purchase Agreement shall prevail.

- 15 -

(b) Each Grantor hereby waives (i) promptness and diligence, (ii) notice of acceptance and notice of the incurrence of any Obligation by any Grantor, (iii) advance notice of any actions taken by the Collateral Agent, any Buyer or any other Person under any Transaction Document or any other agreement, document or instrument relating thereto (except as otherwise provided therein), (iv) all other advance notices, demands and protests (except as otherwise provided herein), and all other formalities of every kind in connection with the enforcement of the Secured Obligations, the omission of or delay in which, but for the provisions of this subsection (b), might constitute grounds for relieving such Grantor of any such Grantor's obligations hereunder and (v) any requirement that the Collateral Agent or any Buyer protect, secure, perfect or insure any security interest or other lien on any property subject thereto or exhaust any right or take any action against any Grantor or any other Person or any collateral. Notwithstanding the aforesaid, the relevant Grantor shall be entitled to receive notice in the event that the Collateral Agent or any Person on its behalf shall exercise or enforce its rights hereunder.

(c) All of the obligations of the Grantors hereunder are joint and several.

The release or discharge of any Grantor by the Collateral Agent shall not release or discharge any other Grantor from the obligations of such Person hereunder.

- 16 -

SECTION 11. Miscellaneous.

(b) No failure on the part of the Secured Parties to exercise, and no delay in exercising, any right hereunder or under any other Transaction Document shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The rights and remedies of the Secured Parties provided herein and in the other Transaction Documents are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law.
