      This Amendment No. 3 (the "Amendment") amends and supplements the Tender
Offer Statement on Schedule TO (the "Schedule TO"), filed with the Securities
and Exchange Commission (the "Commission") on May 24, 2002 by Cardinal Health,
Inc., an Ohio corporation ("Cardinal"), and Garden Merger Corp., a Delaware
corporation and a wholly owned subsidiary of Cardinal ("Subcorp"), as amended by
Amendment No. 1 filed with the Commission on May 28, 2002 and Amendment No. 2
filed with the Commission on May 30, 2002, relating to the offer by Subcorp to
purchase all outstanding shares of common stock, par value $0.01 per share (the
"Shares"), of Boron, LePore & Associates, Inc., a Delaware corporation ("BLP")
for $16.00 per Share, net to the seller in cash, upon the terms and subject to
the conditions set forth in the Offer to Purchase, dated May 24, 2002 (the
"Offer to Purchase") and in the related Letter of Transmittal, copies of which
were filed previously with the Schedule TO as Exhibits (a)(1)(A) and (a)(1)(B),
respectively (which, together with any amendments or supplements to the Offer to
Purchase and the Letter of Transmittal, collectively constitute the "Offer").

ITEM 11.  ADDITIONAL INFORMATION.

      Item 11 of the Schedule TO is hereby amended and supplemented by the
following:

      On or about June 4, 2002, Cardinal received a copy of a putative class
action complaint captioned Rodanthe Lengle v. Patrick G. LePore, et. al. This
complaint, which Cardinal understands was filed in the Superior Court of New
Jersey, Chancery Division, Passaic County, alleges, among other matters, that
the Directors of BLP violated the terms of BLP's Certificate of Incorporation in
connection with certain provisions in the Merger Agreement relating to the
appointment of directors; breached their fiduciary duties by the failure to
maximize shareholder value and by breaching their duty of due care and loyalty;
and breached their duties to shareholders by failing to disclose certain
information to shareholders in connection with the proposed tender offer. The
plaintiff has brought suit on behalf of a purported class of the public
shareholders of BLP and seeks, among other things, temporary, preliminary and
permanent injunctive relief to enjoin the closing of the Offer. The complaint
also alleges that Cardinal aided and abetted a breach of fiduciary duty by the
other defendants.

      BLP and Cardinal believe the allegations contained in the complaint are
entirely without merit and intend to defend against the claims vigorously.

      A copy of the complaint has been filed as an exhibit to Amendment No. 2 to
the Schedule 14D-9 filed by BLP on June 5, 2002 and is incorporated in the
Schedule TO, as amended, by reference. The foregoing description of the
complaint is qualified in its entirety by reference to the text of that exhibit.
