WLJAMS Pursuant to our telephone conversation today have revised the Stipulated Protective Order which you previously forwarded and am enclosing a copy. Specifically the Order is changed in Paragraphs (second and third sentences), (B), (C) and (C), all as we discussed. n order to move the possibility of settlement discussions off dead center we would appreciate it if you would bring along with you on Monday those license agreements with manufacturers of cartridges. As underst and it this includes only Mattei, Milton Bradley and Coleco, as well, of course, as A tari whose two licenses we already have. As have mentioned to Ted it would also be very beneficial in discussing settlement if we were to know what you consider infringing games, as well as t he criteria you are using to determine infringement. n response to our interrogatories you have identified the games "Fishing Derby", "Boxing", "Tennis" and "ce Hockey". t would be well to know if these are the only games which you consider to infringe and also why these games are considered to be infringements and others are not. am looking forward to seeing you on Monday. Very truly yours, TOH:nad Enclosure FLEHR, HOHBACH, TEST, AL~ERBERT ThZ~rbert
