                  Omnicare Reports Second-Quarter 2004 Results
                          and Revises Earnings Guidance

COVINGTON, Ky., July 26, 2004 - Omnicare, Inc. (NYSE:OCR), a leading provider of
pharmaceutical care for the elderly, reported today financial results for its
second-quarter ended June 30, 2004 versus the comparable prior-year period, as
follows:

     o   Earnings per diluted share increased 32% to 58 cents
     o   Net income rose 39% to $60.5 million
     o   Earnings before interest, income taxes, depreciation and amortization
         (EBITDA) increased 22% to $126.0 million
     o   Sales grew 20% to $1,010.6 million

         Results for the second quarter of 2003 included a previously announced
special charge of $4.1 million pretax ($2.5 million aftertax) relating to the
early redemption of a portion of the Company's 5% convertible subordinated
debentures prior to June 30, 2003. Adjusting for this special item in the
prior-year period, results for the quarter ended June 30, 2004 were as follows:

     o   Adjusted earnings per diluted share increased 23% to 58 cents
     o   Adjusted net income rose 31% to $60.5 million
     o   EBITDA increased 22% to $126.0 million
     o   Sales grew 20% to $1,010.6 million

         Commenting on the results for the quarter, Joel F. Gemunder, Omnicare's
president and chief executive officer said, "While we saw increases in sales of
20% and in adjusted diluted earnings per share of 23%, for the second quarter of
2004, our earnings were below our expectations as well as those of Wall Street.
In analyzing this quarter's results, we believe our anticipated earnings growth
was affected by the cumulative impact of a variety of external factors, in
particular intensified pricing pressures and drug pricing issues and an
unexpected shift in our payor mix toward Medicaid during the quarter that
impacted the margins in our institutional pharmacy business. In light of these
factors, we have revised our outlook for the year and now expect diluted
earnings per share to be in the range of $2.35 to $2.45 for 2004.





<Page>


         "We have begun taking aggressive actions to ameliorate the impact of
these external factors and restore margins. We are realigning our operating
costs to adjust to the current dynamic in pricing, including the acceleration of
initiatives to reduce costs and enhance productivity as well as putting into
place innovative new purchasing programs. We will also accelerate the
implementation of several longer-term initiatives to take advantage of the
inherent strength and leverage of our pharmacy business's national platform,
including using an advanced "hub and spoke" system and increased utilization of
our two centralized repackaging facilities. As the year progresses, we also
expect to realize the full synergies from both purchasing and consolidation
savings for acquisitions completed in 2004.

         "Our growth strategy over the years has enabled us to substantially
increase the size of our core pharmacy business with the ability to generate
substantial economies of scale and enhance our comparative cost advantages. This
has helped mitigate reimbursement risks while strengthening our position,
maximizing cash flow generation and enhancing the efficiency of our operations.

         "We view the current situation as a rough patch, the type of which
we've managed through before, and which we are confident we will address
successfully and efficiently. The long-term fundamentals underpinning Omnicare's
business remain intact and we believe our company's strategy continues to be
sound and appropriate," said Gemunder.

Financial Position
         "Our ongoing focus on enhancing cash flow continued during the second
quarter," said Gemunder. "Cash flow from operations for the second quarter ended
June 30, 2004 was $66.0 million as compared with $23.8 million for the first
quarter ended March 31, 2004. In the first quarter of 2004, a broad-based
slowdown occurred in payments from the Illinois Department of Public Aid
(Illinois Medicaid), impacting cash flow by approximately $29 million. We are
pleased to report that Illinois Medicaid released funds in the second quarter of
2004, allowing us to recover the full $29 million that had been delayed in the
prior quarter. Lastly, as reported in the first quarter of 2004, a statewide
administrative backup in the transfer of Medi-Cal provider numbers, which
affected the California-based pharmacies acquired in the SunScript acquisition
and other acquisitions, created a temporary delay in cash receipts of
approximately $19 million. The delay continued during the second quarter of
2004, which has now resulted in approximately $24 million being temporarily
delayed by the state of California. We expect to receive these funds in due
course.

         "Nonetheless, the strength of our cash flow during the quarter allowed
us to continue our capital deployment strategies in acquisition efforts, advance
purchases of pharmaceuticals (pre-buys) and paying down debt. Pre-buys for the
second quarter of 2004 were $48.1 million as compared with $25.6 million for the
first quarter of 2004. Furthermore, we paid down $29.1 million in bank debt
during the second quarter of 2004."

         Cash flow from operations for the quarter ended June 30, 2004 was $66.0
million as compared with $114.7 million in the prior-year quarter. As noted
above, Omnicare received the full $29 million in delayed payments from Illinois
Medicaid in the current quarter and similarly, in the quarter ended June 30,
2003, $51 million in payments from Illinois Medicaid were received that had
previously been delayed. Furthermore, as previously mentioned, pre-buys in the
quarter ended June 30, 2004 were $48.1 million as compared with $33.2 million
for the quarter ended June 30, 2003.

         During the quarter ended June 30, 2004, the Company maintained a strong
financial position with cash balances of approximately $175 million and total
debt-to-total capitalization of 39.4%, down 840 basis points from the comparable
prior-year quarter and 140 basis points down from the first quarter of 2004.

         To facilitate comparisons and to enhance the understanding of core
operating performance, certain discussion herein includes financial measures
that are adjusted from the comparable amount under Generally Accepted Accounting
Principles (GAAP) to exclude the impact of the above-mentioned special item. For
a detailed presentation of reconciling items and related definitions and
components, please refer to the attached schedules or to reconciliation
schedules posted on the Company's Web site at www.omnicare.com.

Institutional Pharmacy Business
         Omnicare's institutional pharmacy business generated record sales of
$976.8 million for the second quarter of 2004, 22% higher than the $802.8
million reported in the comparable prior-year quarter of 2003. Operating income
in this business reached $120.5 million, 26% higher than the $95.8 million
recorded in the second quarter of 2003. At June 30, 2004, Omnicare served
approximately 1,054,000 beds versus approximately 938,000 at June 30, 2003, an
increase of approximately 12%.

         "The year-over-year growth in our pharmacy business is the product of
aggressive execution of our acquisition strategy. Not only did we benefit from
the acquisitions and related integration efforts in 2003, we have also increased
the number of beds served through a number of smaller acquisitions throughout
the first half of 2004," said Gemunder. "Also contributing to year-over-year
growth was the expansion of our clinical and other service programs as well as
further market penetration of newer branded drugs and drug price inflation,
offset in part by increasing use of generic drugs and the previously-mentioned
pricing issues.

         "On a sequential basis, our results were impacted by margin compression
resulting primarily from increased competitive pricing and drug-specific pricing
issues under various state Medicaid programs. While we have not recently seen a
significant increase in the number of legislative changes in Medicaid pharmacy
reimbursement formulas, many states have used their broad administrative powers
to


                                       3



<Page>


limit or reduce drug-specific prices on generic drugs, often with limited or
no prior public notice. These factors, along with the shift in payor mix toward
lower-margin Medicaid business, resulted in sequentially lower margins for the
quarter. Then too, the full synergies from both purchasing and consolidation
savings for acquisitions completed in 2004 have yet to be realized. We expect
such synergies to be realized over the balance of the year.

         "As we have done successfully in the past, we are committed to
addressing the intensified pricing pressures and Medicaid issues we are seeing
in institutional pharmacy. We are realigning our operating costs to bring them
in line with the current pricing dynamics. We are doing this through the
acceleration of our cost reduction and productivity enhancement initiatives and
through innovative procurement programs we have already implemented, which are
yielding cost savings beyond previous expectations. As also mentioned earlier,
we will accelerate several longer-term plans to realize substantial operating
efficiencies, including the rollout of a "hub and spoke" configuration for our
pharmacy business beginning in select markets and specific measures to increase
the utilization of our two centralized repackaging facilities to benefit our
local pharmacies," Gemunder commented.

         "These initiatives are in place or are in the process of being
implemented and their impact is expected to have a gradual positive effect on
our results as we progress through this year and next year.

         "Then too, we believe that realizing the synergies from the number of
smaller acquisitions we have made year-to-date will have a positive impact on
our margins over the balance of the year. That said, we plan to continue to be
aggressive in our acquisition program as industry consolidation makes even more
strategic and economic sense today. Longer term, we see growth in our higher
margin businesses such as specialty pharmacy services and pharmaceutical
informatics also having a salutary impact on margins," commented Gemunder.

CRO Business
         Omnicare Clinical Research, the Company's contract research (CRO)
business, generated revenues of $33.8 million on a GAAP basis for the second
quarter of 2004, versus the comparable prior-year quarter's revenues of $41.2
million. Included in both periods were reimbursable out-of-pocket expenses,
totaling $4.5 million in the 2004 period and $5.9 million in the 2003 period.
Excluding these reimbursable out-of-pocket expenses, adjusted revenues were
$29.3 million versus the $35.4 million recorded on this basis in the 2003
period. Operating income in the second quarter of 2004 was $3.3 million versus
the $4.5 million earned during the prior-year period. Backlog in our CRO
business at June 30, 2004 grew to approximately $200 million.

         "Our CRO business performed in line with our expectations for the
quarter against tough year-over-year comparisons," said Gemunder. "Performance
on a sequential basis continued to show improvement in profitability. During the
quarter,


                                       4



<Page>


we saw solid new business wins and our PeriApproval and Geriatric Clinical
Studies Unit continued to exceed growth expectations. These factors, combined
with productivity improvements and cost reduction efforts, point to improving
performance during the second half of the year.

         "While our CRO business at times experiences short-term volatility, we
see a positive long-term outlook in Omnicare Clinical Research as we benefit
from the streamlining and globalization of our business, our unique capabilities
in the geriatric market and the strength of our presence in the overall drug
development marketplace."

Six Month Results
         Financial results for the six months ended June 30, 2004, as compared
with the same period of 2003, were as follows:

     o   Earnings per diluted share increased 37% to $1.18
     o   Net income rose 48% to $123.9 million
     o   EBITDA grew 30% to $256.0 million
     o   Sales grew 21% to $1,992.9 million

         The first half of 2003 included the previously discussed charge of $4.1
million pretax related to the early redemption of the 5% convertible notes.
Adjusting for this special item in the prior-year period, results for the first
half of 2004 were as follows:

     o   Adjusted earnings per diluted share increased 34% to $1.18
     o   Adjusted net income rose 43% to $123.9 million
     o   EBITDA grew 30% to $256.0 million
     o   Sales grew 21% to $1,992.9 million

         For the 2004 year-to-date period, cash flow from operations on a GAAP
basis was $89.8 million, versus the $120.0 million generated in the first half
of 2003. Both periods reflect second quarter pre-buys of $48.1 million in 2004
and $33.2 million in 2003.

NeighborCare Transaction
         On June 4, 2004, Omnicare commenced a tender offer for all of the
outstanding shares of the common stock of NeighborCare, Inc. (NASDAQ: NCRX) for
$30.00 per share in cash. Omnicare's tender offer price represents a 70% premium
over NeighborCare's closing stock price on May 21, the last day of trading
before Omnicare's proposed offer to acquire NeighborCare was made public on May
24. It also represents a 40% premium over the 30-day trading average prior to
the announcement of the offer, a 30% premium to Wall Street's median price
target for NeighborCare's stock over the next 12 months (based on stock price
targets immediately prior to the announcement of Omnicare's offer) and $4.00
more per share than NeighborCare's previous all-time high.

         On July 13, 2004, Omnicare announced that it received a request for
additional information from the Federal Trade Commission (FTC) relating to its
filing under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (HSR Act)
in connection with its tender offer for NeighborCare. The request extends the
waiting period under the HSR Act during which the FTC is permitted to review the
proposed transaction until 10 days after Omnicare has substantially complied
with the request. Omnicare will continue to work with the FTC with respect to
the filing.

         The company's tender offer is scheduled to expire at 5:00 p.m., New
York City time, on July 30, 2004, unless extended.

         Commenting on the tender offer for NeighborCare, Mr. Gemunder said, "We
remain as committed as ever to the acquisition of NeighborCare, which continues
to make compelling business sense. In fact, the generation of economies of scale
in our industry through consolidation has been and will continue to be a major
part of the solution to maintaining quality of care while addressing ongoing
pricing or reimbursement pressures and the need to contain overall healthcare
costs."

Industry Outlook

         "While we continue to see relative stability in the long-term care
industry, we continue to monitor key issues related to healthcare funding,
including the efforts of state Medicaid programs to contain or reduce costs
through the legislative process or by other means, the escalation in drug costs
owing to higher utilization among seniors and the introduction of new, more
efficacious, albeit more expensive, medications, offset somewhat by increasing
use of generic medications."

         Gemunder also noted that the first draft of regulations governing the
implementation of the Medicare drug benefit, signed into law in December 2003
and effective in 2006, is expected to be made public soon and until such
regulations can be fully reviewed, it remains difficult to predict the impact or
outcome of this legislation or of any changes in healthcare policy relating to
the future funding of the Medicare and Medicaid programs. "We believe, however,
that our extensive experience in geriatric pharmaceutical care, the expertise we
have developed in pharmaceutical case management and our vast database on drug
utilization and outcomes in the elderly have positioned us well as the
implementation of the Medicare drug benefit develops.

         "Pharmaceuticals remain the most cost-effective means of treating the
chronic illnesses of the frailest members of our society and, as such, should be
considered nondiscretionary expenditures and should be appropriately funded. The
geriatric pharmaceutical business offers meaningful solutions to containing
healthcare costs while ensuring the well-being of the nation's growing elderly
population," concluded Gemunder.

Omnicare, Inc. and Subsidiary Companies
Footnotes to Financial Information
(000s)
Unaudited


(a) In accordance with Emerging Issues Task Force ("EITF") Issue No. 01-14,
    "Income Statement Characterization of Reimbursements Received for
    'Out-of-Pocket' Expenses Incurred" ("EITF No. 01-14"), Omnicare has recorded
    reimbursements received for "out-of-pocket" expenses on a grossed-up basis
    in the income statement as revenues and direct costs. EITF No. 01-14 relates
    solely to the Company's contract research services business.

(b) The three and six month periods ended June 30, 2003 include a call premium
    and the write-off of a ratable portion of the remaining unamortized debt
    issuance costs, aggregating $4,069 before taxes ($2,523 after taxes),
    relating to the Company's purchase of $106,535 of the aggregate principal
    amount of its 5.0%, $345,000 of convertible subordinated debentures in the
    second quarter of 2003.

(c) EPS (basic EPS; special item, net of taxes; adjusted basic EPS; diluted EPS;
    and adjusted diluted EPS) is reported independently for each amount
    presented. Accordingly, the sum of the individual amounts may not
    necessarily equal the separately calculated adjusted EPS amount for the
    corresponding period.

(d) The three and six month periods ended June 30, 2003 include the dilutive
    effect of the 5% convertible subordinated debentures, which assumes
    conversion using the "if converted" method. Under that method, the
    convertible debentures are assumed to be converted to common shares
    (weighted for the number of days assumed to be outstanding during the
    period), and interest expense, net of taxes, related to the convertible
    debentures is added back to net income. For purposes of the "if converted"
    calculation, 5,808 and 7,260 shares were assumed to be converted for the
    three and six month periods ended June 30, 2003, respectively. Additionally,
    interest expense, net of taxes, of $1,948 and $4,870 for the three and six
    month periods ended June 30, 2003, respectively, was added back to net
    income for purposes of calculating diluted earnings per share using this
    method.

(e) Omnicare believes that investors' understanding of Omnicare's performance is
    enhanced by the Company's disclosure of certain non-GAAP financial measures
    as presented in this financial information. Omnicare management believes
    that the adjusted results provide added insight into the Company's
    performance by focusing on the results generated by the Company's ongoing
    core operations. Management uses the adjusted results for measurement
    purposes. Omnicare's method of calculating these measures may differ from
    those used by other companies and, therefore, comparability may be limited.

(f) The noted presentation excludes amounts that Omnicare is required to record
    in its income statement relating to EITF No. 01-14, as discussed in further
    detail at footnote (a) above.

(g) The noted presentation for the three and six month periods ended June 30,
    2003 excludes the call premium and the write-off of a ratable portion of the
    remaining unamortized debt issuance costs, as discussed in further detail at
    footnote (b) above.

(h) EBITDA represents earnings before interest expense (net of investment
    income), income taxes, depreciation and amortization. Omnicare believes that
    certain investors find EBITDA to be a useful tool for measuring a company's
    ability to service its debt. However, EBITDA does not represent net cash
    flows from operating activities, as defined by U.S. GAAP, and should not be
    considered as a substitute for operating cash flows as a measure of
    liquidity or net income as an indicator of Omnicare's operating performance.
    Omnicare's calculation of EBITDA may differ from the calculation of EBITDA
    by others.

(i) The special item during the three and six month periods ended June 30, 2003
    represents the call premium and the write-off of a ratable portion of the
    remaining unamortized debt issuance costs related to the Company's purchase
    of a portion of its 5.0%, $345,000 of convertible subordinated debentures,
    as discussed in footnote (b) above. Management believes these items are not
    related to the ongoing operations of Omnicare.

(j) Free cash flow represents net cash flows from operating activities less
    capital expenditures and dividends paid by the Company. Omnicare believes
