(b) Second, to be applied in any manner desired by the Lenders to the satisfaction of the Secured Obligations.

(c) Title and Liens. It has and will have good and marketable title to the Collateral from time to time owned or acquired by it, free and clear of all liens, encumbrances, pledges and security interests, and the security interests of the Lenders in the Collateral are perfected lien security interests, prior to the rights of any other secured party or lien creditor. The Borrower will defend its title to the Collateral against the claims and demands of all persons whomsoever.

(d) Negative Pledge. It will not, other than with the prior written consent of the Lenders, (i) grant or create or permit to exist any lien, encumbrance, pledge or security interest on, or in, any of the Collateral except under circumstances where the Borrower has taken immediate action to stay or set aside such levy or attachment and such action is pending or has been finally resolved in favor of the Borrower and the Borrower has remained in control and possession of such Collateral, (ii) permit any levy or attachment to be made against any of the Collateral, or (iii) file any financing statement or mortgage or deed of trust with respect to any of the Collateral, except financing statements and mortgages and deeds of trust in favor of the Lenders.

(e) Risk of Loss; Insurance. Risk of loss of, damage to, or destruction of, the Collateral is on the Borrower to the extent that the Borrower now or hereafter owns or acquires such Collateral. If the Borrower fails to effect and keep in full force and effect insurance covering the Collateral as may be required by the Security Documents, or fails to pay the premiums thereon when due, the Lenders may do so for the account of the Borrower and add the cost thereof to the Secured Obligations. The Borrower hereby assigns and sets over unto the Lenders all moneys which may become payable on account of such insurance, including without limitation any return or unearned premiums which may be due upon cancellation of any such insurance, and directs the insurers to pay the Lenders any amount so due. The Lenders, its officers, employees and authorized agents are hereby irrevocably appointed the attorneys-in-fact of the Borrower to endorse any draft or check which may be payable to the Borrower in order to collect the proceeds of such insurance or any return or unearned premiums. Any balance of insurance proceeds remaining in the possession of the Lenders after payment in full of the Secured Obligations shall be paid to the Borrower or its order.

(f) Care of Collateral by Lenders. The Lenders shall be deemed to have exercised reasonable care in the custody and preservation of such of the Collateral as may be in the Lenders' possession if the Lenders take such action for that purpose as the Borrower owning such Collateral shall request in writing, provided that such requested action shall not, in the judgment of the Lenders, impair the Lenders' security interest in such Collateral or its rights in, or the value of, such Collateral, and provided further that such written request is received by the Lenders in sufficient time to permit the Lenders to take the requested action.

Section 7. Events of Default. If any one or more of the following events shall occur and be continuing or shall exist:

(a) Any representation or warranty herein made by the Borrower shall prove to have been false or misleading in any material respect as of the time made or furnished; or

(b) The Borrower shall default in the due observation or performance of any of the covenants or agreements of the Borrower contained in this Security Agreement and such default shall not be remedied within a period of 10 days after written notice thereof to the Borrower from any of the Lenders; or

(c) An Event of Default (as that term is defined in the Securities Purchase Agreement) shall occur and be continuing or shall exist;

then in any such event, the Lenders shall have such rights and remedies in respect of the Collateral or any part thereof as are provided by the Uniform Commercial Code and such other rights and remedies in respect thereof which it may have at law or in equity or under this Security Agreement, including without limitation the right to enter any premises where any Collateral is located and take possession of the same without demand or notice and without prior judicial hearing or legal proceedings, which the Borrower hereby expressly waives, and to sell all or any portion of the Collateral at public or private sale without prior notice to the Borrower except as otherwise required by law (and if notice is required by law, after ten days' prior written notice) at such place or places and at such time or times and in such manner and upon such terms, whether for cash or on credit, as the Lenders in its sole discretion may determine. Upon any such sale of any of the Collateral, the Lenders may purchase all or any of the Collateral being sold, free from any equity or right of redemption. The Lenders shall apply the proceeds of any such sale to the obligations of the Borrower as provided in Section 5 hereof. If such Proceeds are insufficient to pay the amounts required by law, the Borrower shall be liable for any deficiency in the amount so realized from the Collateral.

In addition, in any such event, the Borrower shall promptly upon demand by the Lenders assemble its Collateral and make it available to the Lenders at a place to be designated by the Lenders which shall be reasonably convenient to the Lenders. The right of the Lenders under this Section to have the Collateral assembled and made available to it is of the essence of this Security Agreement and the Lenders may, at their election, enforce such right by an action in equity for specific performance.

The Borrower, to the extent that it has any right, title or interest in any of the Collateral, waives and releases any right to require the Lenders to collect any of the Secured Obligations from any other of the Collateral under any theory of marshalling of assets, or otherwise, and specifically authorizes the Lenders to apply any of the Collateral against any of the Secured Obligations in any manner that the Lenders may determine.

Section 8. Amendments, Waivers. The provisions of this Security Agreement may from time to time be waived, modified or amended only pursuant to a written instrument duly executed by each of the Lenders.

Section 9. Defeasance. Upon payment in full of the Secured Obligations, this Security Agreement shall terminate and be of no further force and effect; and in such event, the Lenders will, at the expense of the Borrower, redeliver and reassign the Collateral to the Borrower and take all action necessary to terminate the security interests of the Lenders in the Collateral. Until such time, however,

this Security Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns.

Section 10. Miscellaneous. The provisions in Section 7 of the Securities Purchase Agreement shall be applicable to this Security Agreement as though set forth herein in full.
