SOSNOFF HAS SMALL NUMBER OF CAESARS <CAW> SHARES Martin T. Sosnoff said his <MTS Acquisition Corp> to date has received only a "negligible" number of Caesars World Inc shares in response to its 28-dlr- per-share tender offer for all shares. Sosnoff also said he has held preliminary talks with Pratt Hotel Corp <PRAT> and Southmark Corp <SM> on forming a joint venture to enter into talks to acquire Caesars in a friendly transaction in which Sosnoff would have a 50 pct interest and Pratt and Southmark the remainder. Sosnoff said the talks with Pratt and Southmark are not being actively pursued at the presentand may or may not be continued in the future. He said there could be no assurance that a joint venture would be formed or that Caesars would agreed to talks. "Several preliminary contacts with representatives of Caesars have not resulted in any indication that it wishes to enter into such negotiations," Sosnoff said. He said based on talks with staff members of gaming authorities, there can be no assurance that the necessary regulatory review of its bid for Caesars World can be completed by the original April Three expiration date. Sosnoff said it has extended the tender until May 15. The bid remains subject to regulatory approvals and the arrangement of financing. Pratt, which owns the Sands Hotel and Casino in Atlantic City, N.J., where Caesars operates the Boardwalk Regency Hotel and Casino, recently waged an apparently unsuccessful campaign to acquire control of Resorts International Inc <RTA> against New York developer Donald Trump. Southmark owns about 37 pct of Pratt Hotel. Caesars World's boasrd has urged rejection of the offer on the grounds that it is inadequate and has said it would investigate alternative transactions. Sosnoff currently owns about 13.3 pct of Caesars World.
