    The purpose of the Offer and the proposed second-step merger is to enable
Omnicare to acquire control of, and the entire equity interest in, the Company.
Omnicare currently intends, as soon as practicable following consummation of the
Offer, to seek to have Purchaser consummate a merger with and into the Company
(the 'Proposed Merger'), with the Company continuing as the surviving
corporation and a wholly-owned subsidiary of Omnicare. Pursuant to the Proposed
Merger, at the effective time of the Proposed Merger, each then-outstanding
Share that is not owned by Omnicare, Purchaser or other subsidiaries of Omnicare
(other than Shares owned by the Company or held by stockholders, if any, who
properly exercise their appraisal rights under the Delaware General Corporation
Law (the 'DGCL')) would be converted, pursuant to the terms of the Proposed
Merger, into the right to receive an amount in cash equal to the per Share price
paid pursuant to the Offer, without interest.

AMONG JON H. OUTCALT, THE COMPANY AND GENESIS AND THE VOTING AGREEMENT BY AND
AMONG KEVIN B. SHAW, THE COMPANY AND GENESIS, EACH DATED AS OF JULY 28, 2002 (AS

SATISFACTORY TO OMNICARE; (IV) THE PROVISIONS OF SECTION 203 OF THE DGCL NOT

EXISTENCE OF ANY OF THE CONDITIONS TO THE OFFER, INCLUDING THOSE SET FORTH IN
CLAUSES (I) THROUGH (IX) ABOVE, WILL BE DETERMINED BY OMNICARE IN ITS SOLE
DISCRETION. ANY AND ALL OF THE CONDITIONS TO THE OFFER, INCLUDING THOSE SET
FORTH IN CLAUSES (I) THROUGH (IX) ABOVE, MAY BE WAIVED (TO THE EXTENT LEGALLY
PERMISSIBLE) BY OMNICARE OR PURCHASER, IN THEIR SOLE DISCRETION. THE OFFER IS
NOT CONDITIONED ON OBTAINING FINANCING.

    OMNICARE IS SEEKING TO NEGOTIATE WITH THE COMPANY WITH RESPECT TO THE
ACQUISITION OF THE COMPANY BY OMNICARE OR PURCHASER. OMNICARE AND PURCHASER
RESERVE THE RIGHT TO (I) AMEND THE OFFER (INCLUDING AMENDING THE NUMBER OF
SHARES TO BE PURCHASED AND AMENDING THE PURCHASE PRICE) UPON ENTERING INTO A
MERGER AGREEMENT WITH THE COMPANY OR (II) NEGOTIATE A MERGER AGREEMENT WITH THE
COMPANY THAT DOES NOT INVOLVE A TENDER OFFER, PURSUANT TO WHICH MERGER AGREEMENT
PURCHASER WOULD TERMINATE THE OFFER AND THE SHARES WOULD, UPON CONSUMMATION OF
THE MERGER CONTEMPLATED BY SUCH MERGER AGREEMENT, BE CONVERTED INTO CASH, COMMON
STOCK OF OMNICARE AND/OR OTHER SECURITIES IN SUCH AMOUNTS AS ARE NEGOTIATED BY
OMNICARE AND THE COMPANY.

    For purposes of the Offer, Purchaser shall be deemed to have accepted for
payment tendered Shares when, as and if Purchaser gives oral or written notice
of its acceptance to The Bank of New York (the 'Depositary'). Purchaser will pay
for Shares accepted for payment pursuant to the Offer by depositing the purchase
price with the Depositary. The Depositary will act as agent for all tendering
stockholders for the purpose of receiving payments from Purchaser and
transmitting such payments to tendering stockholders whose Shares have been
accepted for payment. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE
PURCHASE PRICE FOR SHARES PURSUANT TO THE OFFER, REGARDLESS OF ANY DELAY IN
MAKING SUCH PAYMENT. If we increase the consideration to be paid for Shares, we
will pay such increased consideration for all Shares purchased pursuant to the
Offer. In all cases, payment for Shares tendered and accepted for payment
pursuant to the Offer will be made only after timely receipt by the Depositary
of (i) certificates for such Shares or timely confirmation of a book-entry
transfer of such Shares into the Depositary's account at the Book-Entry Transfer
Facility, (ii) a properly completed and duly executed Letter of Transmittal and
(iii) any other required documents. Accordingly, payment may be made to
tendering stockholders at different times if delivery of the Shares and other
required documents occurs at different times.

    Subject to the applicable rules and regulations of the Securities and
Exchange Commission, Purchaser reserves the right, in its sole discretion, at
any time and from time to time, (i) to extend the

                                       2








period of time during which the Offer is open, and thereby delaying acceptance
for payment of, and the payment for, any Shares and (ii) to amend the Offer in
any other respect, by giving oral or written notice of such extension or
amendment to the Depositary. Any such extension or amendment will be followed as
promptly as practicable by public announcement thereof and, in the case of such
extension, no later than 9:00 a.m., New York City time on the next business day
after the previously scheduled Expiration Date.

    Purchaser does not currently intend to include a subsequent offering period
in the Offer, although it reserves the right to do so in its sole discretion.
Under the Securities Exchange Act of 1934, as amended (the 'Exchange Act'), Rule
14d-7, no withdrawal rights apply to Shares tendered during a subsequent
offering period and no withdrawal rights apply during the subsequent offering
period with respect to Shares tendered in the Offer and accepted for payment.
Purchaser will pay the same consideration to stockholders tendering Shares in
the Offer or in a subsequent offering period, if it includes one.

    Tendering stockholders may withdraw tenders of Shares made pursuant to the
Offer at any time prior to the Expiration Date. Thereafter, such tenders are
irrevocable, except that they may be withdrawn after October 6, 2002 unless such
Shares are accepted for payment as provided in the Offer to Purchase. If
Purchaser extends the period of time during which the Offer is open, is delayed
in accepting for payment or paying for Shares pursuant to the Offer for any
reason or is unable to accept Shares for payment pursuant to the Offer for any
reason then, without prejudice to Purchaser's rights under the Offer, the
Depositary may, on Purchaser's behalf, retain all Shares tendered, and such
Shares may not be withdrawn except as otherwise provided in the Offer to
Purchase.

    To withdraw tendered Shares, a written or facsimile transmission notice of
withdrawal with respect to the Shares must be timely received by the Depositary
at one of its addresses set forth on the back cover of the Offer to Purchase,
and the notice of withdrawal must specify the name of the person who tendered
the Shares to be withdrawn and the number of Shares to be withdrawn and the name
of the registered holder of Shares, if different from that of the person who
tendered such Shares. If the Shares to be withdrawn have been delivered to the
Depositary, a signed notice of withdrawal with (except in the case of Shares
tendered by an Eligible Institution) signatures guaranteed by an Eligible
Institution must be submitted prior to the release of such Shares. In addition,
such notice must specify, in the case of Shares tendered by delivery of
certificates, the name of the registered holder (if different from that of the
tendering stockholder) and the serial numbers shown on the particular
certificates evidencing the Shares to be withdrawn or, in the case of Shares
tendered by book-entry transfer, the name and number of the account at the
Book-Entry Transfer Facility to be credited with the withdrawn Shares.
Withdrawals may not be rescinded, and Shares withdrawn will thereafter be deemed
not validly tendered for purposes of the Offer. However, withdrawn Shares may be
re-tendered by again following one of the procedures described in 'The
Offer -- Procedures for Tendering Shares' of the Offer to Purchase at any time
prior to the Expiration Date.

    Purchaser will determine, in its sole discretion, all questions as to the
form and validity (including time of receipt) of any notice of withdrawal, and
its determination shall be final and binding. None of Omnicare, Purchaser, the
Depositary, the Information Agent, the Dealer Manager or any other person will
be under any duty to give notification of any defect or irregularity in any
notice of withdrawal or waiver of any such defect or irregularity or incur any
liability for failure to give any such notification.

    Pursuant to Exchange Act Rule 14d-5 and Section 220 of the DGCL, requests
are being made to the Company for use of the Company's stockholder lists and
security position listings for the purpose of disseminating the Offer to holders
of Shares. Upon compliance by the Company with such requests, the Offer to
Purchase and the related Letter of Transmittal will be mailed to record holders
of Shares and will be furnished to brokers, dealers, commercial banks, trust
companies and similar persons whose names, or the names of whose nominees,
appear on the stockholder lists for subsequent transmittal to beneficial owners
of Shares.

    The information required to be disclosed by Exchange Act Rule 14d-6(d)(1) is
contained in the Offer to Purchase and is incorporated herein by reference.
