The 'shared attorney' method of imputing Rule 15(c)(3) notice is based on the notion that, when an originally named party and the party who is sought to be added are represented by the same attorney, the attorney is likely to have communicated to the latter party that he may very well be joined in the action. This method has been accepted by other Courts of Appeals and by district courts within this Circuit. See Gleason v. McBride, 869 F.2d 688, 693 (2d Cir. 1989); Barkins v. Int'l Inns, Inc., 825 F.2d 905, 907 (5th Cir. 1987); Berndt v. State of Tennessee, 796 F.2d 879, 884 (6th Cir. 1986); Heinly, 146 F.R.D. at 107; Kinnally, 748 F. Supp. at 1141.
