which there is a reclassification or change (including a change to the right to receive cash or other property) of the common stock into which this Note may be converted (other than a change in par value, or from no par value to a specified par value, or as a result of a subdivision or combination, but including any change in the shares into two or more classes or series of shares), then the Holder shall have the right thereafter to receive upon conversion of this Note the kind and amount of shares of stock and other securities, property, cash or any combination thereof receivable upon such reclassification, change, consolidation or merger by a holder of the number of the common stock for which this Note was convertible immediately prior to such reclassification, change, consolidation or merger. Upon any adjustment of the Conversion Price, then and in each such case the Maker Kips Bay hall give written notice thereof, by first-class mail, postage prepaid, addressed to the registered Holder affected by such adjustment at the address of the Holder as shown on the books of Kips Bay, which notice shall state the Conversion Price resulting from such adjustment and the increase or decrease, if any, in the number of shares receivable at such price upon the conversions of the Convertible Note, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.

that are issuable upon exercise or exchange of common stock equivalents shall be deemed outstanding immediately after the issuance of such common stock equivalents.

     Upon any adjustment of the Conversion Price, then and in each such case Kips Bay shall give written notice thereof, by first-class mail, postage prepaid, addressed to the registered holder affected by such adjustment at the address of the Holder as shown on the books of Kips Bay, which notice shall state the Conversion Price resulting from such adjustment and the increase or decrease, if any, in the number of shares receivable at such price upon the conversions of the Convertible Note, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.
