Notwithstanding the foregoing, the Pledgor may at any time sell or otherwise dispose of, in whole or in part, for fair market value as determined by the Board of Directors of the Pledgor the shares of common stock of NSC Corporation owned by the Pledgor, provided however, that any of such shares owned by the Pledgor shall remain subject to the lien of this Pledge Agreement. SECTION 9. Remedies. (a) The Pledgee shall have, in addition to any other rights given under this Pledge Agreement or by law, all of the rights and remedies with respect to the Pledged Collateral of a secured party under the Uniform Commercial Code as in effect in the State of Illinois. In addition, after the occurrence and during the continuance of an Event of Default, the Pledgee shall have such powers of sale and other powers as may be conferred by applicable law. With respect to the Pledged Collateral or any part thereof which shall then be in or shall thereafter come into the possession or custody of the Pledgee or which the Pledgee shall otherwise have the ability to transfer under applicable law, the Pledgee may, in its sole discretion, without notice except as specified below, after the occurrence and during the continuance of an Event of Default, sell or cause the same to be sold at any exchange, broker's board or at public or private sale, in one or more sales or lots, at such price as the Pledgee may deem best, for cash or on credit or for future delivery, without assumption of any credit risk, and the purchaser of any or all of the Pledged Collateral so sold shall thereafter own the same, absolutely free from any claim, encumbrance or right of any kind whatsoever. The Pledgee, may, in its own name, or in the name of a designee or nominee, buy the Pledged Collateral at any public sale and, if permitted by applicable law, buy the Pledged Collateral at any private sale. The Pledgor will pay to the Pledgee all reasonable expenses (including, without limitation, court costs and reasonable attorneys' and paralegals' fees and expenses) of, or incident to, the enforcement of any of the provisions hereof. The Pledgee agrees to distribute any proceeds of the sale of the Pledged Collateral in satisfaction of the obligations under the Reimbursement Agreement and the Pledgor shall remain liable for any deficiency following the sale of the Pledged Collateral. Any balance remaining subsequent to the foregoing shall be returned to the Pledgor or such other persons as are entitled thereto. (b) Unless any of the Pledged Collateral threatens to decline speedily in value or is or becomes of a type sold on a recognized market, the Pledgee will give the Pledgor reasonable notice of the time and place of any public sale thereof, or of the time after which any private sale or other intended disposition is to be made. Any sale of the Pledged Collateral conducted in conformity with reasonable commercial practices of banks, commercial finance companies, insurance companies or other financial institutions disposing of property similar to the Pledged Collateral shall be deemed to be commercially reasonable. Notwithstanding any provision to the contrary contained herein, the Pledgor agrees that any requirements of reasonable notice shall be met if such notice is received by the Pledgor as provided in Section 19 below at least five (5) Business Days before the time of the sale or disposition; provided, however, that the Pledgee may give any shorter notice that is commercially reasonable under the 6 7 circumstances. Any other requirement of notice, demand or advertisement for sale is waived, to the extent permitted by law. (c) In view of the fact that federal and state securities laws may impose certain restrictions on the method by which a sale of the Pledged Collateral may be effected after the occurrence and during the continuance of an Event of Default, the Pledgor agrees that after the occurrence and during the continuance of an Event of Default, the Pledgee may, from time to time, attempt to sell all or any part of the Pledged Collateral by means of a private placement restricting the bidders and prospective purchasers to those who are qualified and will represent and agree that they are purchasing for investment only and not for distribution. In so doing, the Pledgee may solicit offers to buy the Pledged Collateral, or any part of it, from a limited number of investors deemed by the Pledgee, in its reasonable judgment, to be financially responsible parties who might be interested in purchasing the Pledged Collateral. If the Pledgee solicits such offers from not less than four (4) such investors, then the acceptance by the Pledgee of the highest offer obtained therefrom shall be deemed to be a commercially reasonable method of disposing of such Pledged Collateral; provided, however, that this Section does not impose a requirement that the Pledgee solicit offers from four or more investors in order for the sale to be commercially reasonable. SECTION 10. Pledgee Appointed Attorney-in-Fact. The Pledgor hereby appoints the Pledgee its attorney-in-fact, with full authority, in the name of the Pledgor or otherwise, after the occurrence and during the continuance of an Event of Default, from time to time in the Pledgee's sole discretion, to take any action and to execute any instrument which the Pledgee may deem necessary or advisable to accomplish the purposes of this Pledge Agreement, including, without limitation, to exercise voting rights with respect to any of the Pledged Collateral, to receive, endorse and collect all instruments made payable to the Pledgor representing any dividend, interest payment or other distribution in respect of the Pledged Collateral or any part thereof and to give full discharge for the same and to arrange for the transfer of all or any part of the Pledged Collateral on the books of any Corporation to the name of the Pledgee or the Pledgee's nominee. SECTION 11. Waivers. The Pledgor waives presentment and demand for payment of any of the Obligations, protest and notice of dishonor or Event of Default with respect to any of the Obligations and all other notices to which the Pledgor might otherwise be entitled except as otherwise expressly provided herein or in the Reimbursement Agreement.
