The Collateral Agent shall not be obligated to make any sale or other disposition of any 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 Pledgor hereby waives any claims against the Collateral Agent and the Holders arising by reason of the fact that the price at which its respective 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 Obligations, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree, and waives all rights that such Pledgor may have to require that all or any part of such Collateral be marshalled upon any sale (public or private) thereof. Each Pledgor hereby acknowledges that (i) any such sale of its respective 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, and (iii) such actions set forth in clauses (i) and (ii) above shall not adversely affect the commercial reasonableness of any such sale of Collateral.

Any surplus of such cash or Cash Proceeds held by the Collateral Agent and remaining after the indefeasible payment in full in cash of all Obligations under the Notes (together with any matured indemnification obligations as of the date of such payment, but excluding any inchoate or unmatured contingent indemnification obligations) 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 Holders are legally entitled, each Pledgor shall be liable for the deficiency, together with interest thereon at the highest rate specified in any of the applicable Note Transaction Documents for interest on overdue principal thereof or such other rate as shall be fixed by applicable law, together with the reasonable and documented out-of-pocket costs of collection and the reasonable and documented out-of-pocket fees, costs, expenses and other client charges of any attorneys employed by the Collateral Agent to collect such deficiency.

(d)Each Pledgor hereby acknowledges that if the Collateral Agent complies with any applicable state, provincial, or federal law requirements 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 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 each Pledgor lawfully may, such Pledgor 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 Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, such Pledgor hereby irrevocably waives the benefits of all such laws.

12.[Reserved]

(b)No failure on the part of the Collateral Agent to exercise, and no delay in exercising, any right hereunder or under any of the other Note Transaction Documents 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 Collateral Agent or any Holder provided herein and in the other Note Transaction Documents are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law. The rights of the Collateral Agent or any Holder under any of the other Note Transaction Documents against any party thereto are not conditional or contingent on any attempt by such Person to exercise any of its rights under any of the other Note Transaction Documents against such party or against any other Person, including but not limited to, any Pledgor.

(c)To the extent permitted by applicable law, each Pledgor hereby waives promptness, diligence, notice of acceptance and any other notice with respect to any of the Obligations and this Agreement and any requirement that the Collateral Agent exhaust any right or take any action against any other Person or any Collateral.

(e)With respect to severability, Section 9(d) of the Securities Purchase Agreement is hereby incorporated herein by reference as if fully stated herein and shall apply to this Agreement mutatis mutandis.

(f)This Agreement shall create a continuing security interest in the Collateral and shall (i) remain in full force and effect until the indefeasible payment in full in cash of all Obligations under the Notes (together with any matured indemnification obligations as of the date of such payment, but excluding any inchoate or unmatured contingent indemnification obligations), and (ii) be binding on each Pledgor and all other Persons who become bound as debtor to this Agreement in accordance with Section 9-203(d) of the UCC and shall inure, together with all rights and remedies of the Collateral Agent and the Holders hereunder, to the benefit of the Collateral Agent and the Holders and their respective permitted successors, transferees and assigns.
