FOR IMMEDIATE RELEASE

OMNICARE COMMENCES TENDER OFFER

TO ACQUIRE NEIGHBORCARE FOR $30.00 PER SHARE IN CASH

COVINGTON, Ky., June 4, 2004 – Omnicare, Inc. (NYSE: OCR) today announced that it has commenced a tender offer to purchase all of the outstanding shares of NeighborCare, Inc. (NASDAQ: NCRX) common stock for $30.00 per share in cash. The offer represents a 70% premium over NeighborCare’s closing stock price on May 21, 2004 – the last trading day before Omnicare informed NeighborCare’s board in a public letter that it was offering $30.00 per share in cash for the company.

The transaction has a total value of approximately $1.5 billion, which includes the assumption of NeighborCare’s net debt. The transaction is expected to be significantly accretive to Omnicare’s earnings per share.

The tender offer is scheduled to expire at 5:00 p.m., New York City time, on July 7, 2004, unless extended.

Below is the complete text of a letter sent today from Joel F. Gemunder, president and chief executive officer of Omnicare, to NeighborCare shareholders.

June 4, 2004

Dear NeighborCare Shareholder:

As you are aware, Omnicare, Inc. has announced that it has commenced a tender offer to purchase all of the outstanding shares of NeighborCare, Inc. common stock for $30.00 per share in cash.

Omnicare’s all-cash offer will provide you with substantial and immediate value: a 70% premium over NeighborCare’s closing share price on May 21, 2004 – the last trading day before Omnicare publicly announced its offer on May 24. In addition, our offer represents a 40% premium over the 30-day trading average prior to the announcement of our offer, a 30% premium to Wall Street’s median target for NeighborCare’s stock over the next 12 months, and is $4.00 more than NeighborCare’s previous all-time high.

The combination of NeighborCare and Omnicare is a strong strategic fit. It will create a premier institutional pharmacy company with greater resources to provide quality care and expanded services.

Omnicare’s tender offer is scheduled to expire on July 7, 2004, at 5:00 p.m. New York City time, unless extended. While no one can estimate what NeighborCare’s share price would be absent our offer, please keep in mind that within the past 6 months NeighborCare shares have traded as low as $16.81 on May 20, and closed at $17.02 on that day.

Despite the fact that Omnicare’s all-cash offer will provide substantial and immediate value to you – and at a virtually unprecedented 70% premium that we do not believe NeighborCare could achieve on its own, either now or well into the future – your Board of Directors has rejected our offer and refuses even to discuss our offer with us. It is clear that reaching an agreement quickly would be in the best interests of both companies, their shareholders and other constituencies.

SEND A MESSAGE TO NEIGHBORCARE’S BOARD OF DIRECTORS

By tendering your shares, you will be sending a strong message to your Board of Directors that you – the real owners of the company – want to receive maximum value now for your NeighborCare investment. You will also be sending a clear signal to your Board that they should negotiate with Omnicare because a combination of the two companies is just too compelling to ignore.

It is important that you and your fellow NeighborCare shareholders fully understand our genuine attempts to develop an offer that is in your best interests and that provides a fair price for the fair value of your shares.

In a March 30 letter to NeighborCare chairman, president and chief executive officer, John J. Arlotta, we proposed to acquire NeighborCare for $30.00 per share, payable in a “combination of cash and Omnicare common stock.” Omnicare’s intent in offering a combination of cash and stock was to provide a significant premium to you while enabling you to participate in any potential upside by receiving shares in the combined company. But, your Board rejected our proposal without any real explanation and refused any further discussions.

After NeighborCare disappointed the market with its second-quarter earnings announcement on May 12, which prompted analysts to reduce earnings estimates and caused the company’s stock price to drop precipitously, Omnicare’s Board decided that it was in the best interests of the shareholders of both companies that this compelling offer be made public. Despite the recent significant drop in NeighborCare’s share price, we announced on May 24 that we would continue to offer $30 per share for all of NeighborCare’s outstanding shares, while also providing the certainty of all-cash consideration. But again, your Board rejected this compelling offer and continues to refuse to even meet with us to explore the potential of a mutually acceptable transaction.

Your Board’s refusal to act in your best interests left us no choice but to commence our tender offer for NeighborCare shares. Now you have an opportunity to act in your own best interests by tendering your shares.

CALL YOUR BROKER, BANKER OR OTHER FINANCIAL ADVISOR TODAY

ASK WHAT COURSE OF ACTION IS IN YOUR BEST INTEREST

The choice is clear. Tender your shares today. Don’t miss out on the opportunity to realize maximum value for your NeighborCare shares.

Sincerely,

/S/  JOEL F. GEMUNDER
