ITEM 5.  OTHER EVENTS.

         Omnicare, Inc. (the "Company") entered into an Amendment No. 2 to
Credit Agreement dated as of December 21, 1998 (the "Amendment"), with certain
banks (the "Banks") and The First National Bank of Chicago, as one of the Banks
and agent for the Banks (the "Agent"). The Amendment amends the Credit Agreement
dated as of October 22, 1996, among the Borrower, the Banks and the Agent (the
"Original Credit Agreement"), as previously amended, to provide for, among other
things, (i) an increase in the commitment fee rate, the letter of credit fee
rate and the interest rate margin, and (ii) the imposition of a utilization fee
on the outstanding loans under the Original Credit Agreement. The Company also
entered into a 364-Day Credit Agreement dated as of December 21, 1998 (the "1998
Credit Agreement"), with certain banks (the "Lenders") and the Agent as one of
the Lenders and agent for the Lenders. The 1998 Credit Agreement provides for an
additional revolving line of credit in the principal amount of up to
$400,000,000 for a term of 364-days that may, at the option of the Company, be
converted at maturity into a one-year term loan. Except for the commitment fee
rate, the interest rate margin and other pricing terms, the representations,
warranties and covenants of the Company in the 1998 Credit Agreement are
substantially the same as the Original Credit Agreement as amended by the
Amendment.
