Apply that portion of the Collateral consisting of cash or cash equivalent items such as checks, drafts, or deposited funds against any liabilities of Debtor or Pledgor selected by Lender, and for this purpose, Undersigned agrees that cash or equivalents will be considered identical to cash proceeds. Lender shall have the right immediately and without further action by it to set off against the liabilities of Debtor secured hereby all money owned by Lender to Debtor, whether due or not due, and Lender shall be deemed to have exercised the right to set off and to have made a charge against such money at the time of any acceleration upon default even though such charges made are entered on the Lender's books subsequent thereto. 4. Transfer any of the Collateral or evidence thereof in to its own name or that of a nominee and receive all proceeds therefrom and hold the same as security for the liabilities secured hereby to Lender or apply it on or against any such liability. Lender may also demand, collect, receipt for, settle, compromise, adjust, sue for, foreclose, release or realize upon Collateral in its own name or in the name of the Pledgor as Lender may determine. 5.

All such costs shall be secured by the security interest in the Collateral covered herein. 6. Lender shall not be liable for failure to collect any account, enforce any contract right, or for any other act or omission on the part of Lender, its officers, agents or employees, except as the same constitutes a lack of good faith or failure to act in a commercially reasonable manner. Lender shall have acted in a commercially reasonable manner if its action or non-action is consistent with the general usage of lenders in the area of Lender's location at the same time the action or non-action occurs, but this standard shall not constitute disapproval of any procedures which may be otherwise reasonable not require Lender to take necessary steps to preserve rights against prior parties in an instrument or chattel paper.

Undersigned agrees promptly to reimburse Lender for all such expenditures and until such reimbursement the amounts of such expenditures shall be considered a liability of Undersigned to Lender which is secured by this Agreement. In addition, Undersigned shall be liable for and agrees to pay Lender for all costs, attorneys' fees and other disbursements by Lender as allowed by law or provided for herein in the enforcement or collection of any note, warranty or duty of Undersigned to Lender, or in the realization upon or the enforcement or collection of any account, receivable, contract right, promissory note, chattel paper, instrument, document or other Collateral in which Lender has a security interest.

Right of Offset. Any property, tangible or intangible of Undersigned in possession of Lender at any time during the term hereof, or any indebtedness due from Lender to Undersigned and any deposit or credit balances due from Lender to Undersigned, or any of the foregoing of any party hereto, is pledged to secure payment hereof and may at any time while the whole or any part of Undersigned's indebtedness to Lender remains unpaid, whether before or after maturity thereof, be appropriated, held or applied toward payment of any obligation of Undersigned to Lender. 3. Applicable Law. The law of the jurisdiction where Lender is organized or holds its certificate of authority the Undersigned who was entitled thereto shall control this Agreement. 4. Waivers. No act, delay or omission, including Lender's waiver of remedy because of any default hereunder, shall constitute a waiver of any of Lender's rights and remedies under this Agreement or any other agreement between the parties. All rights and remedies of Lender are cumulative and may be exercised singularly or concurrently, and the exercise of any one or more remedy will not be a waiver of any other. No waiver, change, modification or discharge of any of Lender's rights or of Undersigned's duties as so specified or allowed will be effective unless in writing and signed by a duly authorized officer of Lender, and any such waiver will not be a bar to the exercise of any right or remedy or any subsequent default. Undersigned hereby waives: (a) all demands and notices of any action taken by Lender under the Agreement or any other agreement between the parties or in connection with any notes; (b) an indulgence of Lender; and (c) any substitution for, exchange of, or release of all or any part of the Collateral or of other Collateral securing obligations of Debtor to Lender. Undersigned also consents to the addition or release of any person liable on any obligation of Debtor or Undersigned to Lender. 5. Agreement Binding on Assigns.

Rights of Lender Assignable. Lender at any time and at its option may pledge, transfer or assign its rights under this Agreement in whole or in part, and any pledgee, transferee, or assignee shall have all the rights of Lender to the rights or parts thereof so pledged, transferred or assigned. The rights of the Undersigned hereunder may not be assigned. 7. Joint and Several Responsibility of Pledgor. If more than one Undersigned executes the Agreement, their responsibility hereunder shall be joint and several and the reference to undersigned herein shall be deemed to refer to each Undersigned signing this Agreement. 8. Separability of Provisions. If any provision of this Agreement shall for any reason be held to be invalid or unenforceable, such invalidity or unenforceability shall not affect any other provision hereof, and this Agreement shall be construed as if such invalid or unenforceable provision had never been contained herein. 9. Copies. A carbon, photographic, or other reproduction of this Security Agreement or of any financing statement prepaid or filed with respect hereto is sufficient as a financing statement. 10. Notice of Name Change, etc. Undersigned will immediately notify Lender of any change in his, her, its or their name, identity, or organizational or corporate structure.
