The release of shares and payment in lieu of fractional shares pursuant to this Section 11(b) shall be reflected by an appropriate notation to Schedule A hereto. (c) Upon fifteen (15) days prior written notice from Bildner of his intent to sell all or a portion of the Pledged Collateral, the Company may release such Pledged Collateral (such Pledged Collateral shall be referred to herein as the "Released Collateral"), provided that prior to such release Bildner provides the Company with an undertaking that Bildner will pay to the Company in cash an amount equal to 110% of the Fair Market Value of such Released Collateral and any actual amounts paid by the Company in connection with the Guaranty as of the date of such payment within five (5) business days of such sale.
