FOR IMMEDIATE RELEASE: Crystal Lake, Illinois, January 21, 2003


DIVIDEND

     The Board of Directors of AptarGroup, Inc. (NYSE: ATR) today declared a
quarterly cash dividend of $.06 per share. The payment date is February 27,
2003, to stockholders of record as of February 5, 2003.


RIGHTS PLAN

     AptarGroup also announced today that its Board of Directors adopted a
stockholder rights plan to replace the existing rights plan upon its expiration
in April 2003. Terms of this new rights plan are substantially similar to the
expiring plan. Under the plan, AptarGroup will make a dividend of one preferred
stock purchase right for each share of its common stock outstanding as of the
close of business on April 7, 2003. Stockholders are not required to take any
action to receive the rights distribution. The rights will expire in 10 years,
unless earlier redeemed or exchanged by the Company.

     Carl A. Siebel, President and Chief Executive Officer, commented, "The
rights plan is designed to preserve and maximize the value of the Company for
stockholders by ensuring that stockholders receive fair and equal treatment in
the event of an unsolicited takeover attempt. We believe that the stockholder
rights plan is an important tool for the Company."


LICENSE AGREEMENT

     Valois S.A.S., a subsidiary of AptarGroup, Inc., today reported that a
previously announced exclusive license agreement with Wyeth Pharmaceuticals, a
division of Wyeth (NYSE:WYE), was terminated by Wyeth. The agreement related to
Valois' "Combidose" intra-

termination of the agreement enables Valois to offer this technology to other
