Item 5.           Other Events

         On April 22, 2002, Express Scripts received an administrative subpoena
duces tecum issued by the U.S. Attorney's Office in Boston, Massachusetts. On
April 26, 2002, a substantially identical subpoena was issued to Express
Scripts' wholly-owned subsidiary Diversified Pharmaceutical Services, Inc.
("DPS"). The Company has not been advised that it or DPS is a target of any
investigation. The subpoenas state that they are issued in connection with an
investigation of various health care offenses and other federal crimes. The
subpoenas ask for information pertaining to Express Scripts' and DPS'
relationship with TAP Pharmaceuticals, and specifically with respect to TAP's
two principal drugs, Lupron and Prevacid. The Company believes that its services
and business practices are in compliance with all applicable laws, rules and
regulations in all material respects, and it will cooperate in the
investigation. The Company cannot predict the outcome of the investigation at
this time; however, if Express Scripts were to become a target of the
investigation, an unfavorable outcome could result in the imposition of monetary
fines or penalties, or injunctive or administrative remedies.
