(b) Upon the occurrence and during the continuance of a Default, the Lender may, subject to the terms of the Subordination Agreements, enter and take possession of all Collateral and the premises on which they are located, and in the Lender's sole discretion operate and use Borrower's equipment, whether or not Collateral hereunder, complete work in process, apply as Borrower's attorney-in-fact for domestic or foreign patents or other intellectual property rights with respect to inventions and seek registration or assignment, foreign and domestic, of any trademarks, trade names, styles, logos or copyrights, and sell, lease or license the Collateral to third persons or -14- 16 associations without being liable to Borrower on account of any losses, damage or depreciation that may occur as a result thereof so long as Lender shall act reasonably and in good faith; and at the Lender's option and without notice to Borrower (except as specifically herein provided) Lender may sell, lease, assign and deliver the whole or any part of the Collateral, or any substitute therefor or any addition thereto, at public or private sale, for cash, upon credit, or for future delivery, at such prices and upon such terms as Lender deems advisable, including without limitation, the right to sell or lease in conjunction with other property, real or personal, and allocate the sale or lease proceeds among the items of property sold without the necessity of the Collateral being present at any such sale or lease, or in view of prospective purchasers thereof.

Upon such sale, Lender may become the purchaser of the whole or any part of the Collateral, discharged from all claims and free from any right of redemption. In case of any such sale by Lender of all or any of said Collateral on credit or for future delivery, property so sold may be retained by Lender until the selling price is paid by the purchaser.

(e) At Borrower's expense the Lender in its own name or in the name of others may communicate with account debtors in order to verify with them to Lender's satisfaction the existence, amount and terms of any accounts or contract rights and also notify account debtors that Collateral has been assigned to Lender and that payments shall be made directly to Lender. Upon request of Lender, Borrower will so notify such account debtors and will indicate on all billings to such account debtors that their accounts must be paid to Lender. Borrower does hereby appoint Lender and its agents as Borrower's attorney-in-fact to collect, compromise, endorse, sell or otherwise deal with the Collateral or proceeds thereof in its own name or in the name of the Borrower; to endorse the Barrer upon any notes, checks, drafts, money orders, or other instruments, documents, receipts or Collateral that may come into its possession and to apply the same in full or part payment of any amounts owing to Lender; to sign and endorse the Barrer upon any documents, instruments, drafts against account debtors, assignments, verifications and notices in connection with Accounts, and any instrument or document relating thereto or to Borrower's rights therein; and to give written notice to any office and officials of the United States Post Office to effect such change or changes of address that all mail addressed to Borrower may be delivered directly to Lender.

All representations and warranties of the Borrower contained in this Agreement shall survive delivery of the Notes and the making of the Loan herein contemplated. 9.2 Headings. Section headings in the Loan Documents are for convenience of reference only, and shall not govern the interpretation of any of the provisions of the Loan Documents. 9.3 Entire Agreement.

Nothing contained in this Section shall be construed to narrow the scope of the Lender's security interest in any of the Collateral or the perfection or priority thereof or to impair or otherwise limit any of the rights, powers, privileges or remedies of the Lender hereunder except (and then only to the extent) mandated by Revised Article 9 to the extent then applicable. - 19 - 21 IN WITNESS WHEREOF, the Borrower and the Lender have executed this Agreement as of the date first above written.
