3. The Commission's October 19, 1999 Order also requested the International Securities Exchange ("ISE") to participate with the options exchanges in the development of an inter-market linkage plan. The ISE has filed an application with the Commission to register as a national securities exchange. See Securities Exchange Act Release No. 41439 (May 24, 1999) 64 FR 29367 (June 1, 1999). The ISE submitted a plan identical to that filed by Amex and CBOE. Because the Commission has not approved the ISE's application for registration as a national securities exchange, however, the ISE may not be a signatory to a linkage plan at this time.
