            This Amendment No. 2 amends and supplements the Tender Offer
Statement on Schedule TO, as previously amended and supplemented, originally
filed with the Securities and Exchange Commission (the "Commission") on
August 8, 2002 (as previously amended and supplemented, 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

ITEM 11.  Additional Information

         The first paragraph under Section 18 ("Legal Proceedings") of the Offer
to Purchase is hereby amended and restated in its entirety as follows:

         On August 1, 2002, Omnicare commenced litigation against the Company,
the Company's Board of Directors and Genesis and Geneva Sub in the Court of
Chancery of the State of Delaware alleging, among other things, that the
Company's Board of Directors violated their fiduciary and statutory duties to
the Company's stockholders by entering into the Genesis Agreement and the
Voting Agreements.

         On August 12, 2002, Omnicare filed a First Amended Complaint which
alleged, among other things and in addition to the breaches of fiduciary duties
by the Company's Board of Directors, that the grant by Messrs. Outcalt
and Shaw of an irrevocable proxy, coupled with an interest, to Genesis to vote
all of their shares of the Company's Class B Common Stock violated the Company's
amended and restated certificate of incorporation and irrevocably converted
those shares of Class B Common Stock (holding ten votes per share) into shares
of Class A Common Stock (holding only one vote per share). Accordingly,
Omnicare has sought an order:

         a.  Declaring that the Voting Agreements entered into by Messrs.
             Outcalt and Shaw violate the Company's amended and restated
             certificate of incorporation and by entering into these Voting
             Agreements, Messrs. Outcalt and Shaw automatically and irrevocably
             converted their shares of Class B Common Stock into shares of
             Class A Common Stock as provided in the amended and restated
             certificate of incorporation;

         b.  In the alternative, declaring that the Company's Board of Directors
             violated Section 141 of the DGCL in agreeing to the terms of the
             Genesis Agreement and the associated Voting Agreements, and,
             therefore, that the Genesis Agreement is null and void;

         c.  In the alternative, preliminarily and permanently enjoining (i) the
             Company, the Company's Board of Directors, Genesis, Geneva Sub, and
             their respective officers, directors, employees, agents and all
             persons acting on their behalf from taking further steps or any
             actions with respect to the Voting Agreements and/or the Genesis
             Agreement; and (ii) Genesis and Geneva Sub, and their respective
             officers, directors, employees, agents and all persons acting on
             their behalf from aiding and abetting the Company's Board of
             Directors' breaches of their fiduciary duties; and

         d.  Declaring that the termination fee provision in the Genesis
             Agreement is unreasonable, invalid and unenforceable; and

         e.  Granting Omnicare such further relief as may be just and proper,
             including the costs and disbursements of this action and reasonable
             attorneys' fees.
