2. Representations, Warranties and Agreements. Debtor represents, warrants and agrees that:

2.6. Debtor will keep all tangible Collateral in good repair, working order and condition, normal depreciation excepted, and will, from time to time, replace any worn, broken or defective parts thereof.

Upon execution of this Agreement, Debtor will provide Collateral Agent with evidence of such insurance in the form of copies of the policies thereof or certificates of insurance therefor. Debtor shall give Collateral Agent immediate notice of the expiration of cancellation of any such insurance and shall immediately obtain replacement insurance coverage and provide evidence thereof to Collateral Agent.

In addition, Debtor authorizes Collateral Agent to file any financing statement Collateral Agent deems necessary, describing any liens held by Secured Parties hereunder. Such financing statements may describe the Collateral in the same manner as described herein or may contain an indication or description of the Collateral that describes such property in any other manner as Collateral Agent may determine, in its reasonable discretion, is necessary to ensure the perfection of the Security Interest, including, without limitation, describing such property as “all assets” or “all personal property.”

2.16. Debtor will not use or keep any Collateral, or permit it to be used or kept, for any unlawful purpose or in violation of any federal, state or local law, statute or ordinance.

2.17. If Debtor at any time fails to perform or observe any agreement contained in this Section 2, and if such failure shall continue for a period of 30 calendar days after Collateral Agent gives Debtor written notice thereof, Collateral Agent may (but need not) perform or observe such agreement on behalf and in the name, place and stead of Debtor (or, at Collateral Agent’s option, in Collateral Agent’s own name) and may (but need not) take any and all other actions that Collateral Agent may reasonably deem necessary or desirable to cure or correct such failure. Debtor shall pay Collateral Agent on demand the amount of all monies expended and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by Collateral Agent in connection with or as a result of Collateral Agent performing or observing such agreements or taking such actions, together with interest thereon from the date expended or incurred by Collateral Agent at the highest rate then applicable to any of the Obligations. To facilitate the performance or observance by Collateral Agent of such agreements of Debtor (in the event Debtor does not cure any such failure during the above-described 30-day period), Debtor hereby irrevocably appoints (which appointment is coupled with an interest) Collateral Agent, or its delegate, as the attorney-in-fact of Debtor with the right (but not the duty) from time to time to create, prepare, complete, execute, deliver, endorse or file, in the name and on behalf of Debtor, any and all instruments, documents, financing statements, and other agreements and writings required to be obtained, executed, delivered or endorsed by Debtor under this Section 2.

3. Account Verification and Collection Rights of Collateral Agent. Collateral Agent shall have the right to verify any accounts in the name of Debtor or in Collateral Agent’s own name; and Debtor, whenever requested pursuant to the terms of this Section, shall furnish Collateral Agent with duplicate statements of the accounts, which statements may be mailed or delivered by Collateral Agent for that purpose. Collateral Agent may at any time after the occurrence of an Event of Default notify any account debtor, or any other person obligated to pay any amount due, that such chattel paper, account, or other right to payment has been assigned or transferred to Collateral Agent for security and shall be paid directly to s Collateral Agent. If Collateral Agent so requests at any time after the occurrence of an Event of Default, Debtor will so notify such account debtors and other obligors in writing and will indicate on all invoices to such account debtors or other obligors that the amount due is payable directly to Collateral Agent. At any time after Collateral Agent or Debtor gives such notice to an account debtor or other obligor, Collateral Agent may (but need not), in Collateral Agent’s own name or in Debtor’s name, demand, sue for, collect or receive any money or property at any time payable or receivable on account of, or securing, any such chattel paper, account, or other right to payment, or grant any extension to, make any compromise or settlement with or otherwise agree to waive, modify, amend or change the obligations (including collateral obligations) of any such account debtor or other obligor.

Any “Event of Default” (as defined in such agreement) by Debtor under the Notes or any other agreement evidencing the Obligations, which default is not cured within any grace period granted with respect to such default or, if no specific grace period is granted with respect to such default, where such default is not cured within five (5) business days after written notice thereof from any Secured Party;

Debtor’s failure to comply with any representation, warranty or covenant hereunder if not cured within thirty (30) days after written notice, unless such failure is such that it cannot be cured in which event no such cure period shall apply;

Attachment, execution or levy on any of the Collateral.

5. Remedies upon Event of Default. Upon the occurrence of an Event of Default and at any time thereafter, Collateral Agent may exercise any one or more of the following rights and remedies:

6. Other Personal Property. Unless at the time Collateral Agent takes possession of any tangible Collateral, or within seven days thereafter, Debtor gives written notice to Collateral Agent of the existence of any goods, papers or other property of Debtor, not affixed to or constituting a part of such Collateral, but which are located or found upon or within such Collateral, Collateral Agent shall not be responsible or liable to Debtor for any action taken or omitted by or on behalf of Secured Parties with respect to such property without actual knowledge of the existence of any such property or without actual knowledge that it was located or to be found upon or within such Collateral.

7. Assignment of Insurance. Debtor hereby assigns to Collateral Agent, as additional security for the payment of the Obligations, any and all moneys (including but not limited to proceeds of insurance and refunds of unearned premiums) due or to become due under, and all other rights of Debtor under or with respect to, any and all policies of insurance covering the Collateral, and Debtor hereby directs the issuer of any such policy to pay any such moneys directly to Collateral Agent. Both before and after the occurrence of an Event of Default, Collateral Agent may (but need not), in Collateral Agent’s name or in Debtor’s name, execute and deliver proofs of claim, receive all such moneys, endorse checks and other instruments representing payment of such moneys, and adjust, litigate, compromise or release any claim against the issuer of any such policy.

8. Indemnity. Debtor agrees to defend, indemnify and hold harmless the Secured Parties and their respective officers, employees, and agents against all obligations, demands, claims, and liabilities claimed or asserted by any third party that such third party has an interest in the Collateral that is senior to or superior to the security interest granted to Secured Parties hereunder, except for such losses arising from or out of the gross negligence or willful misconduct of the Secured Party seeking such indemnity.

9. Termination of Security Interest. In the event of conversion of the Notes to capital stock of Debtor as provided in the Notes, this Agreement and the security interest granted hereunder shall automatically terminate. In the event any holder of Notes shall exercise all or any portion of the optional conversion rights in such holder’s Note, any rights of such holder in the Collateral and under this Agreement shall thereupon terminate.

10. Conduct No Waiver: Remedies Cumulative. No course of dealing on the part of any Secured Party, nor any delay or failure on the part of any Secured Party in exercising any right, power or privilege shall operate as a waiver of such right, power or privilege or otherwise prejudice the rights or remedies of such Secured Party; nor shall any single or partial exercise thereof preclude any further exercise thereof or the exercise of any other right, power or privilege. No right or remedy conferred upon or reserved to any Secured Party under this Agreement or any other agreement relating to issuance of the Notes or any one of them, is intended to be exclusive of any other right or remedy, and every right and remedy shall be cumulative and in addition to every other right or remedy granted hereunder or thereunder or now or hereafter existing under.

11. Collateral Agent. Debtor acknowledges and agrees that Collateral Agent shall have the right to act on behalf of the Secured Parties (but not to the exclusion of the individual rights of the Secured Parties set forth herein), and the Securities Parties acknowledge and agree that Debtor may rely upon actions taken by Collateral Agent in its capacity as such for purposes of exercising the rights and remedies of the Secured Parties hereunder. For purposes of this Agreement, the Collateral Agent shall constitute a Secured Party.

12. Miscellaneous.

12.1. This Agreement can be waived, modified, amended, terminated or discharged, and the Security Interest can be released, only explicitly in a writing signed by the Secured Parties holding not less than a majority in interest of the Notes.

Mere delay or failure to act shall not preclude the exercise or enforcement of any of such Secured Party’s rights or remedies.

12.2. All notices to be given to Debtor or Collateral Agent hereunder shall be deemed sufficiently given if delivered or mailed by registered or certified mail, postage prepaid, to the party entitled thereto at its address set forth above or at such other address as Debtor or Collateral Agent may subsequently provide to the other in the manner prescribed by this Section.

12.4. This Agreement shall be binding upon and inure to the benefit of Debtor and each Secured Party and their respective successors and assigns and shall take effect when signed by Debtor and delivered to Collateral Agent, and Debtor waives notice of Secured Parties’ acceptance hereof.
