Nothing in this Section 6 shall be deemed an authorization for Debtor to take any action that it is otherwise expressly prohibited from undertaking by way of other provision of this Agreement.

7. Default and Remedies.

7.1. Default. Debtor shall be deemed in default under this Agreement upon the occurrence of an Event of Default.

7.2. Remedies. Upon the occurrence of any such Event of Default, Secured Party shall have the rights of a secured creditor under the UCC, all rights granted by this Agreement and by law, including, without limiting the foregoing, (a) the right to require Debtor to assemble the Collateral and make it available to Secured Party at a place to be designated by Secured Party, and (b) the right to take possession of the Collateral, and for that purpose Secured Party may enter upon premises on which the Collateral may be situated and remove the Collateral therefrom. Debtor hereby agrees that fifteen (15) days’ notice of a public sale of any Collateral or notice of the date after which a private sale of any Collateral may take place is reasonable. In addition, Debtor waives any and all rights that it may have to a judicial hearing in advance of the enforcement of any of Secured Party’s rights and remedies hereunder, including, without limitation, Secured Party’s right following an Event of Default to take immediate possession of Collateral and to exercise Secured Party’s rights and remedies with respect thereto. Secured Party may also have a receiver appointed to take charge of all or any portion of the Collateral and to exercise all rights of Secured Party under this Agreement. Secured Party may exercise any of its rights under this Section 7.2 without demand or notice of any kind. The remedies in this Agreement, including without limitation this Section 7.2, are in addition to, not in limitation of, any other right, power, privilege, or remedy, either in law, in equity, or otherwise, to which Secured Party may be entitled. No failure or delay on the part of Secured Party in exercising any right, power, or remedy will operate as a waiver thereof, nor will any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right hereunder. All of Secured Party’s rights and remedies, whether evidenced by this Agreement or by any other agreement, instrument or document shall be cumulative and may be exercised singularly or concurrently.

7.3. Standards for Exercising Rights and Remedies. To the extent that applicable law imposes duties on Secured Party to exercise remedies in a commercially reasonable manner, Debtor acknowledges and agrees that it is not commercially unreasonable for Secured Party (a) to fail to incur expenses reasonably deemed significant by Secured Party to prepare Collateral for disposition, (b) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (c) to fail to exercise collection remedies against account debtors or other persons obligated on Collateral or to fail to remove liens or encumbrances on or any adverse claims against Collateral, (d) to exercise collection remedies against account debtors and other persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (f) to contact other persons, whether or not in the same business as Debtor, for expressions of interest in acquiring all or any portion of the Collateral, (g) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (h) to dispose of Collateral by utilizing Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets, (i) to dispose of assets in wholesale rather than retail markets, (j) to disclaim disposition warranties, (k) to purchase insurance or credit enhancements to insure Secured Party against risks of loss, collection or disposition of Collateral or to provide to Secured Party a guaranteed return from the collection or disposition of Collateral, or (l) to the extent deemed appropriate by Secured Party, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist Secured Party in the collection or disposition of any of the Collateral. Debtor acknowledges that the purpose of this Section is to provide non-exhaustive indications of what actions or omissions by Secured Party would fulfill Secured Party’s duties under the UCC in Secured Party’s exercise of remedies against the Collateral and that other actions or omissions by Secured Party shall not be deemed to fail to fulfill such duties solely on account of not being indicated in this Section. Without limitation upon the foregoing, nothing contained in this Section shall be construed to grant any rights to Debtor or to impose any duties on Secured Party that would not have been granted or imposed by this Agreement or by applicable law in the absence of this Section.

4

7.4. Marshalling. Secured Party shall not be required to marshal any present or future Collateral for, or other assurances of payment of, the Obligations or to resort to such Collateral or other assurances of payment in any particular order, and all of its rights and remedies hereunder and in respect of such Collateral and other assurances of payment shall be cumulative and in addition to all other rights and remedies, however existing or arising. To the extent that it lawfully may, Debtor 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 Secured Party’s rights and remedies 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, Debtor hereby irrevocably waives the benefits of all such laws.

7.5. Application of Collateral Proceeds. The proceeds and/or avails of the Collateral, or any part thereof, and the proceeds and the avails of any remedy hereunder (as well as any other amounts of any kind held by Secured Party at the time of, or received by Secured Party after, the occurrence of an Event of Default) shall be paid to and applied as follows:

(a) First, to the payment of reasonable costs and expenses, including all amounts expended to preserve the value of the Collateral, of foreclosure or suit, if any, and of such sale and the exercise of any other rights or remedies, and of all proper fees, expenses, liability and advances, including reasonable legal expenses and attorneys’ fees, incurred or made hereunder by Secured Party;

(b) Second, to the payment to Secured Party of the amount then owing or unpaid on the Note (to be applied first to accrued interest and fees and second to outstanding principal) and all amounts owed under any of the other Transaction Documents or other documents included within the Obligations; and

(c) Third, to the payment of the surplus, if any, to Debtor, its successors and assigns, or to whosoever may be lawfully entitled to receive the same.

In the absence of final payment and satisfaction in full of all of the Obligations, Debtor shall remain liable for any deficiency.

8. Miscellaneous.

8.1. Notices. Any notice required or permitted hereunder shall be given in the manner provided in the subsection titled “Notices” in the Purchase Agreement, the terms of which are incorporated herein by this reference.

5

8.2. Non-waiver. No failure or delay on Secured Party’s part in exercising any right hereunder shall operate as a waiver thereof or of any other right nor shall any single or partial exercise of any such right preclude any other further exercise thereof or of any other right.

8.3. Amendments and Waivers. This Agreement may not be amended or modified, nor may any of its terms be waived, except by written instruments signed by Debtor and Secured Party.

8.4. Assignment. This Agreement shall be binding upon and inure to the benefit of Secured Party and Debtor and their respective successors and assigns; provided, however, that Debtor may not sell, assign or delegate rights and obligations hereunder without the prior written consent of Secured Party.

8.5. Cumulative Rights, etc. The rights, powers and remedies of Secured Party under this Agreement shall be in addition to all rights, powers and remedies given to Secured Party by virtue of any applicable law, rule or regulation of any governmental authority, or the Note, all of which rights, powers, and remedies shall be cumulative and may be exercised successively or concurrently without impairing Secured Party’s rights hereunder. Debtor waives any right to require Secured Party to proceed against any person or entity or to exhaust any Collateral or to pursue any remedy in Secured Party’s power.

8.6. Partial Invalidity. If any part of this Agreement is construed to be in violation of any law, such part shall be modified to achieve the objective of the parties to the fullest extent permitted and the balance of this Agreement shall remain in full force and effect.

8.7. Expenses. Debtor shall pay on demand all reasonable fees and expenses, including reasonable attorneys’ fees and expenses, incurred by Secured Party in connection with the custody, preservation or sale of, or other realization on, any of the Collateral or the enforcement or attempt to enforce any of the Obligations which are not performed as and when required by this Agreement.

The provisions set forth in the Purchase Agreement to determine the proper venue for any disputes are incorporated herein by this reference.

8.10. Waiver of Jury Trial.
