         This Amendment No. 35 amends and supplements the Tender Offer
Statement on Schedule TO filed with the Securities and Exchange Commission (the
"Commission") on August 8, 2002 (the "Schedule TO") by Omnicare, Inc., a
Delaware corporation ("Omnicare"), and NCS Acquisition Corp., a Delaware
corporation ("Purchaser") and a wholly-owned subsidiary of Omnicare. The
Schedule TO relates to a tender offer by Purchaser to purchase all of the
outstanding shares of class A common stock, par value $0.01 per share, and class
B common stock, par value $0.01 per share, of NCS HealthCare, Inc. (the
"Company") for a purchase price of $3.50 per share, net to the seller in cash,
without interest thereon, upon the terms and subject to the conditions set forth
in the Offer to Purchase, dated August 8, 2002 (the "Offer to Purchase"), and in
the related Letter of Transmittal (the "Letter of Transmittal" which, together
with the Offer to Purchase, as hereby or hereafter amended or supplemented from
time to time, constitute the "Offer"). Copies of the Offer to Purchase and the
related Letter of Transmittal are filed with the Schedule TO as Exhibits
(a)(1)(A) and (a)(1)(B), respectively. Capitalized terms used and not defined
herein shall have the meanings assigned such terms in the Offer to Purchase
and the Schedule TO.

Item 5.   Past Contacts, Transactions, Negotiations and Agreements.

          Section 11 ("Background of the Offer") of the Offer to Purchase is
hereby amended by adding the following to the end of such Section:

          On December 13, 2002, the Company invited Omnicare and Genesis Health
Ventures, Inc. ("Genesis") each to submit its "best and highest offer" to
acquire all of the outstanding shares of class A and class B common stock of the
Company by 6:00 p.m. (E.S.T.) on December 15, 2002. In addition, the Company
provided Omnicare and Genesis with Rules and Procedures for Submission of
Proposals for NCS HealthCare, Inc. setting forth the rules and procedures
established by the Company for the submission of proposals, the full text of
which is filed as Exhibit (a)(1)(EEE) hereto and is incorporated herein by
reference.

          Following receipt of the request for proposals from the Company,
Genesis and Omnicare discussed termination of the NCS/Genesis Merger Agreement
and negotiated and executed a Termination and Settlement Agreement, dated
December 15, 2002 (the "Termination Agreement"). The Termination Agreement
provides, among other things, that Genesis will terminate the NCS/Genesis Merger
Agreement in accordance with its terms by sending written notice of such
termination to the Company on December 16, 2002 (which will also result in
termination of the voting agreements between Genesis and Messrs. Outcalt and
Shaw). In addition, Genesis and Omnicare agreed to release the other party from
any claims arising from the NCS/Genesis Merger Agreement and not to commence any
action against the other party arising out of or in connection with the
NCS/Genesis Merger Agreement. Omnicare also agreed that prior to the closing of
a transaction with the Company, it would pay Genesis an amount in cash equal to
$22 million less any termination fees paid by or on behalf of the Company to
Genesis under the NCS/Genesis Merger Agreement. The full text of the Termination
Agreement is filed as Exhibit (a)(5)(D) hereto and is incorporated herein by
reference.

          On December 16, 2002, Omnicare issued a press release announcing the
Termination and Settlement Agreement, the full text of which is filed as Exhibit
(a)(1)(FFF) hereto and is incorporated herein by reference.

Item 12.  Exhibits.

          Item 12 is hereby amended and supplemented with the following
information:

          Exhibit (a)(1)(EEE) Rules and Procedures for Submission of Proposals
for NCS HealthCare, Inc., dated December 13, 2002.

December 16, 2002.

          Exhibit (a)(5)(D) Termination and Settlement Agreement, dated
December 15, 2002, between Omnicare, Inc., Genesis Health Ventures, Inc. and
Geneva Sub, Inc.
