SUMMARY TERM SHEET

This summary term sheet is a brief description of the offer being made by Omnicare, Inc. through Nectarine Acquisition Corp., a wholly owned subsidiary of Omnicare, to purchase all of the outstanding shares of common stock, including the associated preferred stock purchase rights, of NeighborCare, Inc., at a price of $32.00 per share, net to the seller in cash, without interest. The following are some of the questions you, as a shareholder of NeighborCare, may have and answers to those questions. You should carefully read this supplement, the offer to purchase and the related revised (green) letter of transmittal in their entirety, because the information in this summary term sheet is not complete and additional important information is contained in the remainder of this supplement, the offer to purchase and the related revised (green) letter of transmittal.

How is Omnicare amending the offer?

Omnicare is amending its tender offer to increase the offer price from $30.00 to $32.00 per share, net to the seller in cash. The $32.00 per share price represents an 81% premium over the shares’ closing price on May 21, 2004, which was the last trading day prior to Omnicare’s announcement of its intention to commence a tender offer for the shares of NeighborCare at the initial price of $30.00, and a 50% premium over the 30-day average trading price of NeighborCare common stock prior to the public announcement of Omnicare’s initial offer. You should obtain a recent market quotation for the Shares in deciding whether to tender your Shares.

In addition, the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, or the HSR Act, as amended, expired at 11:59 p.m., on June 15, 2005. Accordingly, the condition to the offer relating to the expiration or termination of any applicable waiting period under applicable antitrust laws, including the HSR Act, has been satisfied.

What does the board of directors of NeighborCare think of this offer?

NeighborCare’s board of directors has not approved the offer as of the date of this supplement. On June 14, 2004, NeighborCare published and issued to you (and filed with the Securities and Exchange Commission, or the SEC) a statement recommending that you reject the original offer.

What are the classes and amounts of securities sought in the offer?

We are seeking to purchase all of the outstanding shares of common stock, including the associated preferred stock purchase rights, of NeighborCare. On the date of this supplement, Omnicare beneficially owns 100 shares of the common stock of NeighborCare. NeighborCare’s recent public disclosure provided that, as of May 5, 2005, there were 44,132,466 shares of NeighborCare common stock outstanding (exclusive of the 100 shares owned by Omnicare), an additional 259,360 shares reserved for issuance in connection with NeighborCare’s joint plan of reorganization confirmed by the Bankruptcy Court on September 20, 2001 and as of September 30, 2004, an additional 2,235,029 shares issuable upon or otherwise deliverable in connection with the exercise of outstanding options. The number of outstanding shares and shares reserved for issuance are contained in NeighborCare’s Form 10-Q, filed on May 9, 2005. Based upon this publicly available information, 37,301,564 shares must be tendered in order to satisfy the condition to the offer that shares representing at least 80% of the total voting power of all of the outstanding securities of NeighborCare be tendered in the offer.

How much are you offering to pay for my shares and what is the form of payment? Will I have to pay any fees or commissions?

We are offering to pay $32.00 per share for the common stock, including the associated preferred stock purchase rights, of NeighborCare, net to you in cash, without interest. If you tender your shares to us in the offer, you will not have to pay brokerage fees, commissions or similar expenses. If you own your shares through a broker or other nominee, and your broker tenders your shares on your behalf, your broker or nominee may charge you a fee for doing so. You should consult your broker or nominee to determine whether any charges will apply.

1

Do you have the financial resources to make payment?

Yes. In order to finance the purchase of all of the shares pursuant to our tender offer and the proposed merger, refinance certain debt of Omnicare and NeighborCare, and their respective subsidiaries, provide for working capital and pay fees and expenses related to the transactions, Omnicare will use a combination of cash on hand and new debt financing. We have obtained a commitment letter, as amended, to provide such new debt financing from JPMorgan Chase Bank, N.A., Lehman Commercial Paper Inc., an affiliate of Lehman Brothers Inc., a Dealer Manager, SunTrust Bank, Canadian Imperial Bank of Commerce and Merrill Lynch Bank USA, or, collectively, the Commitment Parties, pursuant to which, subject to specified conditions, the Commitment Parties have agreed to provide to Omnicare $2.75 billion, or the Credit Facilities. The proceeds of the Credit Facilities may be used to finance the offer and the proposed merger, to refinance certain existing indebtedness of Omnicare and NeighborCare and to pay related fees and expenses, as well as, after the initial funding date, for general corporate purposes of Omnicare and its subsidiaries in the ordinary course of business. The commitments are subject to customary conditions, including, among other things, the execution and delivery of satisfactory loan documentation relating to the Credit Facilities containing representations, warranties, covenants and events of default substantially the same as those in Omnicare’s existing credit agreement, dated as of June 13, 2003, among Omnicare, JPMorgan Chase Bank, Lehman Commercial Paper Inc., SunTrust Bank, as administrative agent, CIBC Inc. and the other parties signatory thereto. Omnicare expects to repay amounts outstanding under the new debt financings out of cash from operations and the proceeds from other short- and long-term debt or other financings, although Omnicare does not have any firm plans with respect to other capital raising transactions. We will need approximately $1.5 billion to purchase all of the outstanding shares (assuming the exercise of all outstanding stock options) pursuant to the offer and to pay related fees and expenses. See section 10 (“Source and Amount of Funds”) of the offer to purchase and section 8 (“Source and Amount of Funds”) of this supplement.

Is your financial condition relevant to my decision to tender in the offer?

The financial condition of Omnicare is relevant to any decision to tender shares because this tender offer is contingent upon our having received proceeds of the financings contemplated by our commitment letter, as amended, or such other financings that are sufficient, together with cash on hand, to consummate our offer and the proposed merger and to refinance all debt of Omnicare and NeighborCare that is or could be required to be repurchased or becomes, or could be declared, due and payable as a result of our offer or the proposed merger or the financing thereof and to pay all related fees and expenses. Although we have obtained a commitment letter, we cannot guarantee that Omnicare will be able to obtain the financings contemplated by the commitment letter, as amended. You should consider all of the information concerning the financial condition of Omnicare included or incorporated by reference into the offer to purchase and this supplement before deciding to tender shares in our offer. See section 9 (“Certain Information Concerning Purchaser and Omnicare—Available Information”) of the offer to purchase.

Have you held discussions with NeighborCare?

We have tried repeatedly to discuss with NeighborCare the potential acquisition of NeighborCare by Omnicare. We made a proposal to acquire all of the outstanding shares of common stock, including the associated preferred stock purchase rights, of NeighborCare in a negotiated merger transaction, but NeighborCare was not interested in discussing a transaction. We and our advisors are prepared to meet with NeighborCare and its advisors to negotiate the terms of a definitive transaction. See section 11 (“Background of the Offer”) of the offer to purchase and section 9 (“Background of the Offer”) of this supplement.

2

How long do I have to decide whether to tender in the offer?

You have until 5:00 p.m., New York City time, on June 30, 2005, to decide whether to tender your shares in the offer. Further, if you cannot deliver everything required to make a valid tender to The Bank of New York, the depositary for the offer, prior to such time, you may be able to use a guaranteed delivery procedure to tender your shares in the offer. See section 4 (“Procedure for Tendering Shares”) of the offer to purchase and section 3 (“Procedure for Tendering Shares”) of this supplement.

How do I tender my shares?

To tender shares, you must deliver the certificates representing your shares, together with a completed letter of transmittal, to The Bank of New York, the depositary for the offer, not later than the time that the offer expires. If your shares are held in street name by your broker, dealer, commercial bank, trust company or other nominee, such nominee can tender your shares through The Depository Trust Company. If you cannot deliver everything required to make a valid tender to the depositary prior to the expiration of the offer, you may have a limited amount of additional time by having a broker, a bank or other fiduciary which is a member of the Securities Transfer Agents Medallion Program or other eligible institution, guarantee that the missing items will be received by the depositary within three business days after the expiration of the offer. However, the depositary must receive the missing items within that three business day period. See section 4 (“Procedure for Tendering Shares”) of the offer to purchase and section 3 (“Procedure for Tendering Shares”) of this supplement.

If I already tendered my shares in the offer, do I have to do anything now?

No. You do not have to take any action with respect to any shares of common stock previously validly tendered and not properly withdrawn. If the offer is completed, these shares will be accepted for payment and you will receive the increased offer price of $32.00 per share, net to you in cash. See section 3 (“Procedure for Tendering Shares”) of this supplement.

Until what time can I withdraw tendered shares?

You can withdraw tendered shares at any time until the offer has expired and, if we have not agreed to accept your shares for payment by June 30, 2005, you can withdraw them at any time after such date until we accept shares for payment. If we decide to provide a subsequent offering period, we will accept shares tendered during that period immediately and, thus, you will not be able to withdraw shares tendered during any subsequent offering period. See section 5 (“Withdrawal Rights”) of the offer to purchase.

How do I withdraw tendered shares?

To withdraw shares, you must deliver a written notice of withdrawal, or a facsimile of one, with the required information to The Bank of New York, the depositary for the offer, while you have the right to withdraw the shares. See section 5 (“Withdrawal Rights”) of the offer to purchase.

When and how will I be paid for my tendered shares?

Subject to the terms and conditions of the offer, we will pay for all validly tendered and not properly withdrawn shares promptly after the expiration date of the offer, subject to the satisfaction or waiver of the conditions to the offer, as set forth in section 11 (“Conditions to the Offer”) of this supplement. We will pay for your validly tendered and not properly withdrawn shares by depositing the purchase price with The Bank of New York, the depositary for the offer, which will act as your agent for the purpose of receiving payments from us and transmitting such payments to you. In all cases, payment for tendered shares will be made only after timely receipt by The Bank of New York of certificates for such shares (or of a confirmation of a book-entry transfer of such shares as described in section 4 (“Procedure for Tendering Shares”) of the offer to purchase) and a properly completed and duly executed revised letter of transmittal and any other required documents for such shares.

If I decide not to tender, how will the offer affect my shares?

If the proposed merger with Omnicare takes place, shareholders not tendering in the offer will receive the same amount of cash per share that they would have received had they tendered their shares in the offer. Therefore, if the proposed merger with Omnicare takes place, the only difference to you between tendering your shares and not tendering your shares is that you will be paid earlier if you tender your shares. If the offer is successful, Omnicare intends to consummate the proposed merger as promptly as practicable. However, if the proposed merger with Omnicare does not take place and the offer is consummated, the number of shareholders and shares that are still in the hands of the public may be so small that there will no longer be an active public trading market, or, possibly, any public trading market, for the shares, which may affect prices at which shares trade. Also, as described below, NeighborCare may cease making filings with the SEC or otherwise cease being subject to the SEC rules relating to publicly held companies.

Can the offer be extended and under what circumstances?

We may, in our sole discretion, extend the offer at any time or from time to time. We may extend the offer, for example, if any of the conditions specified in section 11 (“Conditions to the Offer”) of this supplement are not satisfied prior to the scheduled expiration date of the offer.

We may also elect to provide a “subsequent offering period” for the offer. A subsequent offering period, if we include one, will be an additional period of time beginning after we have purchased shares tendered during the offer, during which shareholders may tender their shares and receive payment for shares validly tendered. We do not currently intend to include a subsequent offering period, although we reserve the right to do so. See section 1 (“Terms of the Offer; Expiration Date”) of the offer to purchase and section 1 (“Amended Terms of the Offer; Expiration Date”) of this supplement.

How will I be notified if the offer is extended?

If we decide to extend the offer or provide for a subsequent offering period, we will inform The Bank of New York, the depositary for the offer, of that fact and will make a public announcement of the extension, not later than 9:00 a.m., New York City time, on the business day after the day on which the offer was scheduled to expire.

What are the most significant conditions to the offer?

The most significant conditions to the offer are the following, any or all of which may be waived, to the extent legally permissible, by us in our sole discretion:

— NeighborCare’s shareholders having validly tendered and not properly withdrawn prior to the expiration date of the offer that number of shares representing, together with the shares owned by Omnicare, at least eighty percent of the total voting power of all of the outstanding securities of NeighborCare entitled to vote generally in the election of directors or in a merger, calculated on a fully diluted basis after consummation of the offer;

— The Purchaser being satisfied in its reasonable discretion that the acquisition of shares pursuant to the offer has been approved pursuant to Subchapter F of Chapter 25 of the Pennsylvania Business Corporation Law, or the PBCL, or that Subchapter F of Chapter 25 of the PBCL does not otherwise restrict the offer and the proposed merger or any subsequent business combination involving NeighborCare and Omnicare;

— NeighborCare’s board of directors redeeming the preferred stock purchase rights, or Omnicare being satisfied in its reasonable discretion that the preferred stock purchase rights have been invalidated or are otherwise inapplicable to the offer and the proposed merger;

4

— Omnicare having available to it proceeds of the financings contemplated by its commitment letter, as amended, or other such financings that are sufficient, together with cash on hand, to consummate the offer and the proposed merger and to refinance all debt of NeighborCare and Omnicare that is or could be required to be repurchased or becomes, or could be declared, due and payable as a result of the offer or the proposed merger or the financing thereof and to pay all related fees and expenses; and

— NeighborCare not having entered into or effectuated any agreement or transaction with any person or entity having the effect of impairing Omnicare’s ability to acquire NeighborCare or otherwise diminishing the economic value to Omnicare of the acquisition of NeighborCare.

The satisfaction or existence of any of the conditions to our offer, including those summarized above, will be determined by Omnicare in its reasonable discretion. For a complete list of the conditions to the offer, see section 11 (“Conditions to the Offer”) of this supplement.

Do I have statutory dissenters’ rights in the offer?

No. However, if you so choose, you may be entitled to exercise dissenters’ rights in the proposed merger. You will be entitled to dissenters’ rights in the proposed merger only if (i) prior to the proposed merger (A) the shares are no longer designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or listed on a national securities exchange and (B) the shares are beneficially and of record held by 2,000 persons or less or (ii) Nectarine Acquisition Corp. owns 80% of the shares and the proposed merger is consummated as a “short-form” merger pursuant to Section 1924(b)(1)(ii) of the PBCL. If you elect to dissent in circumstances in which dissenters’ rights are applicable and comply with the provisions of the PBCL relating to dissenters’ rights, your shares, at the effective time of the proposed merger, will not entitle you to receive the per share amount being paid by us in the offer as set forth above. You will instead be entitled to receive either the amount that the surviving corporation estimates to be the fair value of your shares or, if you disagree with that valuation, whatever consideration may be determined to be due to you by a court pursuant to the applicable provision of the PBCL. Your right to seek an appraisal under Pennsylvania law will be forfeited if you do not comply with the requirements of the PBCL relating to dissenters’ rights. See section 16 (“Certain Legal Matters; Regulatory Approvals”) of the offer to purchase.

What is the market value of my shares as of a recent date?

On June 15, 2005, the last full trading day before we amended the offer upon the terms set forth in this supplement, the closing price of a share of common stock of NeighborCare was $32.16. On May 21, 2004, the last full trading day before we publicly announced our offer for all of the outstanding shares of common stock of NeighborCare, the closing price of common stock of NeighborCare was $17.67. On June 3, 2004, the last full trading day before we commenced the tender offer, the closing price of a share of common stock of NeighborCare was $29.95. We advise you to obtain a recent quotation for shares before deciding whether to tender your shares. See section 5 (“Price Range of Common Stock; Dividends”) of this supplement.

Who can I talk to if I have questions about the offer?

You can call Innisfree M&A Incorporated, the information agent for the offer, at (877) 825-8964 (toll free) or (212) 750-5833 (call collect), or Lazard Frères & Co. LLC and Lehman Brothers Inc., the dealer managers for the offer at (212) 632-1535 or (212) 526-7850, respectively.

To: The Holders of Common Stock of NeighborCare, Inc.

INTRODUCTION

The following information (the “Supplement”) amends and supplements the Offer to Purchase, dated June 4, 2004 (the “Offer to Purchase”), of Nectarine Acquisition Corp., a Delaware corporation (“Purchaser”) and a wholly owned subsidiary of Omnicare, Inc., a Delaware corporation (“Omnicare”). Pursuant to this Supplement, Purchaser is now offering to purchase all of the issued and outstanding shares of common stock, par value $0.02 per share, including the Rights (as defined below) (the “Shares”), of NeighborCare, Inc., a Pennsylvania corporation (the “Company”), at a price of $32.00 per Share, net to the seller in cash, without interest, upon the terms and subject to the conditions set forth in the Offer to Purchase, this Supplement and the related revised (green) Letter of Transmittal (which together, as amended, supplemented or otherwise modified from time to time, constitute the “Offer”).

This Supplement should be read in conjunction with the Offer to Purchase. Except as otherwise set forth in this Supplement and the revised (green) Letter of Transmittal, the terms and conditions previously set forth in the Offer to Purchase and related original (blue) Letter of Transmittal remain applicable in all respects to the Offer. Unless the context requires otherwise, all capitalized terms used but not defined in this Supplement have the meanings ascribed to them in the Offer to Purchase.

Procedures for tendering Shares are set forth in Section 4 (“Procedure for Tendering Shares”) of the Offer to Purchase as amended and supplemented by Section 3 (“Procedure for Tendering Shares”) of this Supplement. Tendering shareholders may continue to use the original (blue) Letter of Transmittal and the original (green) Notice of Guaranteed Delivery previously circulated with the Offer to Purchase, or the revised (green) Letter of Transmittal and the revised (beige) Notice of Guaranteed Delivery circulated with this Supplement. Although the original (blue) Letter of Transmittal previously circulated with the Offer to Purchase refers only to the Offer to Purchase, shareholders using such document to tender their Shares will nevertheless be deemed to be tendering pursuant to the amended Offer (including the amendments and supplements made by this Supplement) and will receive $32.00 per Share, net to the seller in cash, without interest, for each Share validly tendered and not properly withdrawn and accepted for payment pursuant to the Offer, subject to the conditions of the Offer.

SHARES PREVIOUSLY VALIDLY TENDERED AND NOT PROPERLY WITHDRAWN CONSTITUTE VALID TENDERS FOR PURPOSES OF THE OFFER. SHAREHOLDERS ARE NOT REQUIRED TO TAKE ANY FURTHER ACTION WITH RESPECT TO SUCH SHARES IN ORDER TO RECEIVE THE INCREASED OFFER PRICE IF SHARES ARE ACCEPTED FOR PAYMENT AND PAID FOR BY PURCHASER PURSUANT TO THE OFFER, EXCEPT AS MAY BE REQUIRED BY THE GUARANTEED DELIVERY PROCEDURE IF SUCH PROCEDURE WAS UTILIZED.

The purpose of the Offer and the Proposed Merger (as defined below) 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 Share then outstanding that is not owned by Omnicare, Purchaser or other subsidiaries of Omnicare (other than Shares owned by the Company) 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.

In connection with the Offer and the Proposed Merger, Omnicare has notified the Company of its nomination of Michael S. Koeneke, Clay Lifflander and Peter Linneman to replace the three Class II directors of the Company whose term will expire at the Company’s 2005 Annual Meeting of Shareholders.

Omnicare and Purchaser are 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

6

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.

THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (1) THERE BEING VALIDLY TENDERED AND NOT PROPERLY WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER A TOTAL NUMBER OF SHARES REPRESENTING, TOGETHER WITH THE SHARES OWNED BY OMNICARE, AT LEAST EIGHTY PERCENT OF THE TOTAL VOTING POWER OF ALL OF THE OUTSTANDING SHARES OF THE COMPANY ENTITLED TO VOTE GENERALLY IN THE ELECTION OF DIRECTORS OR IN A MERGER, CALCULATED ON A FULLY DILUTED BASIS AFTER CONSUMMATION OF THE OFFER (THE “MINIMUM CONDITION”), (2) THE PURCHASER BEING SATISFIED IN ITS REASONABLE DISCRETION THAT THE ACQUISITION OF SHARES PURSUANT TO THE OFFER HAS BEEN APPROVED PURSUANT TO SUBCHAPTER F OF CHAPTER 25 OF THE PBCL OR THAT SUBCHAPTER F OF CHAPTER 25 OF THE PENNSYLVANIA BUSINESS CORPORATION LAW (THE “PBCL”) DOES NOT OTHERWISE RESTRICT THE OFFER AND THE PROPOSED MERGER OR ANY SUBSEQUENT BUSINESS COMBINATION INVOLVING THE COMPANY AND OMNICARE (THE “SUBCHAPTER 25F CONDITION”), (3) THE COMPANY’S BOARD OF DIRECTORS REDEEMING THE PREFERRED STOCK PURCHASE RIGHTS (THE “RIGHTS”), OR OMNICARE BEING SATISFIED IN ITS REASONABLE DISCRETION THAT THE RIGHTS HAVE BEEN INVALIDATED OR ARE OTHERWISE INAPPLICABLE TO THE OFFER AND THE PROPOSED MERGER (THE “RIGHTS CONDITION”), (4) OMNICARE HAVING AVAILABLE TO IT PROCEEDS OF THE FINANCINGS CONTEMPLATED BY ITS COMMITMENT LETTER, AS AMENDED, OR SUCH OTHER FINANCINGS THAT ARE SUFFICIENT, TOGETHER WITH CASH ON HAND, TO CONSUMMATE THE OFFER AND THE PROPOSED MERGER AND TO REFINANCE ALL DEBT OF THE COMPANY AND OMNICARE THAT IS OR COULD BE REQUIRED TO BE REPURCHASED OR BECOMES, OR COULD BE DECLARED, DUE AND PAYABLE AS A RESULT OF THE OFFER OR THE PROPOSED MERGER OR THE FINANCING THEREOF AND TO PAY ALL RELATED FEES AND EXPENSES (THE “FINANCING CONDITION”) AND (5) THE COMPANY NOT HAVING ENTERED INTO OR EFFECTUATED ANY AGREEMENT OR TRANSACTION WITH ANY PERSON OR ENTITY HAVING THE EFFECT OF IMPAIRING OMNICARE’S ABILITY TO ACQUIRE THE COMPANY OR OTHERWISE DIMINISHING THE ECONOMIC VALUE TO OMNICARE OF THE ACQUISITION OF THE COMPANY (THE “IMPAIRMENT CONDITION”). THE OFFER IS ALSO SUBJECT TO OTHER TERMS AND CONDITIONS CONTAINED IN THE OFFER TO PURCHASE AND THIS SUPPLEMENT.

According to the Company, as of May 5, 2005, 44,132,566 shares of common stock were issued and outstanding, an additional 259,360 shares were reserved for issuance in connection with the Company’s joint plan of reorganization confirmed by the Bankruptcy Court on September 20, 2001 and as of September 30, 2004 there were 2,235,029 shares reserved for issuance upon the exercise of outstanding options to purchase shares. As of the date of this Supplement, Omnicare beneficially owns 100 shares of common stock. The actual minimum number of Shares required to be validly tendered and not properly withdrawn prior to the expiration of the Offer in order for the Minimum Condition to be satisfied will depend on the facts as they exist on the date of purchase.

In the event that the Offer is terminated or not consummated, or after the expiration of the Offer and pending consummation of the Proposed Merger, in accordance with applicable law and any merger agreement that it may enter into with the Company, Omnicare may explore any and all options which may be available. In this regard, and after expiration or termination of the Offer, Omnicare may seek to acquire additional Shares, through open market purchases, block trades, privately negotiated transactions, a tender offer or exchange offer or otherwise, upon such terms and at such prices as Omnicare may determine, which may be more or less than the price offered or paid per Share pursuant to the Offer and could be for cash or other consideration.

THIS OFFER DOES NOT CONSTITUTE A SOLICITATION OF PROXIES FOR ANY MEETING OF SHAREHOLDERS OF THE COMPANY OR A SOLICITATION OF AGENT DESIGNATIONS TO CALL A SPECIAL MEETING OF SHAREHOLDERS OF THE COMPANY. ANY SOLICITATION OF PROXIES WHICH PURCHASER OR OMNICARE MIGHT MAKE WILL BE MADE ONLY PURSUANT TO SEPARATE PROXY OR CONSENT SOLICITATION MATERIALS COMPLYING WITH THE REQUIREMENTS OF SECTION 14(a) OF THE SECURITIES EXCHANGE ACT OF 1934 AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER (THE “EXCHANGE ACT”).

THIS SUPPLEMENT, THE OFFER TO PURCHASE AND THE RELATED REVISED (GREEN) LETTER OF TRANSMITTAL CONTAIN IMPORTANT INFORMATION, AND YOU SHOULD CAREFULLY READ ALL OF THEM IN THEIR ENTIRETY BEFORE YOU MAKE A DECISION WITH RESPECT TO THE OFFER.

THE OFFER

1. Amended Terms of the Offer; Expiration Date.

The discussion set forth in Section 1 (“Terms of the Offer; Expiration Date”) of the Offer to Purchase is hereby amended and supplemented as follows:

The price per Share to be paid pursuant to the Offer has been increased from $30.00 per Share to $32.00 per Share, net to the seller in cash, without interest. All shareholders whose Shares are validly tendered and not properly withdrawn and accepted for payment pursuant to the Offer (including Shares tendered prior to the date of this Supplement) will receive the increased price. The Offer has been previously extended and will expire at 5:00 P.M., New York City time, on June 30, 2005, unless and until the Purchaser shall have extended the period during which the Offer is open. “Expiration Date” means 5:00 P.M., New York City time on June 30, 2005, unless we further extend the period of time for which the Offer is open, in which event, “Expiration Date” means the latest time and date on which the Offer, as so extended, shall expire.

THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THE SATISFACTION OF EACH OF THE CONDITIONS DESCRIBED IN SECTION 11 (“CONDITIONS TO THE OFFER”) OF THIS SUPPLEMENT.

Under Exchange Act Rule 14d-11, Purchaser may, subject to certain conditions, provide a subsequent offering period of from three to 20 business days following the Expiration Date. A subsequent offering period would be an additional period of time, following the expiration of the Offer and the purchase of Shares in the Offer, during which shareholders may tender Shares not tendered in the Offer. A subsequent offering period, if one is included, is not an extension of the Offer, which already would have been completed.

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 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 shareholders tendering Shares in the Offer or in a subsequent offering period, if it includes one.

On the date of this Supplement, Omnicare beneficially owns 100 shares of common stock of the Company. According to the Company’s Form 10-Q, filed on May 9, 2005, as of May 5, 2005, there were 44,132,466 shares outstanding (exclusive of the 100 shares owned by Omnicare), 259,360 shares reserved for issuance in connection with the Company’s joint plan of reorganization confirmed by the Bankruptcy Court on September 20, 2001 and according to the Company’s Form 10-K, filed on March 16, 2005, as of September 30, 2004, there were an additional 2,235,029 shares issuable upon or otherwise deliverable in connection with the exercise of outstanding options. Based upon this publicly available information, 37,301,564 shares must be tendered in order to satisfy the condition to the offer that shares representing at least 80% of the total voting power of all of the outstanding securities of the Company be tendered in the offer.

For purposes of the Minimum Condition, “fully diluted basis” assumes that all outstanding stock options are fully exercisable. The actual minimum number of Shares required to satisfy the Minimum Condition will depend on the facts as they exist on the date of purchase.

2. Acceptance for Payment and Payment.

The first paragraph under Section 3 (“Acceptance for Payment and Payment”) of the Offer to Purchase is hereby amended and restated in its entirety as follows:

Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any such extension or amendment), we will accept for payment and promptly pay for all Shares that are validly tendered on or prior to the Expiration Date and not properly withdrawn pursuant to the Offer, subject to the satisfaction or waiver of the conditions set forth in Section 11 (“Conditions to the Offer”) of

9

this Supplement. In addition, we reserve the right, subject to compliance with the Exchange Act Rule 14e-1(c), to delay the acceptance for payment or payment for Shares pending receipt of any regulatory or governmental approvals to the Offer as described under Section 16 (“Certain Legal Matters; Regulatory Approvals”) of the Offer to Purchase and Section 12 (“Certain Legal Matters; Regulatory Approvals”) of this Supplement. For a description of our right to terminate the Offer and not accept for payment or pay for Shares or to delay acceptance for payment or payment for Shares, see Section 2 (“Extension of Tender Period; Termination; Amendment”) of the Offer to Purchase.

3. Procedure for Tendering Shares.

The discussion set forth in Section 4 (“Procedure for Tendering Shares”) of the Offer to Purchase is hereby amended and supplemented as follows:

Tendering shareholders may continue to use the original (blue) Letter of Transmittal and the original (green) Notice of Guaranteed Delivery previously circulated with the Offer to Purchase, or the revised (green) Letter of Transmittal and the revised (green) Notice of Guaranteed Delivery circulated with this Supplement. Although the original (blue) Letter of Transmittal previously circulated with the Offer to Purchase refers only to the Offer to Purchase, shareholders using such document to tender their Shares will nevertheless be deemed to be tendering pursuant to the amended Offer (including the amendments and supplements made by this Supplement) and will receive $32.00 per Share, net to the seller in cash, without interest and less required withholding taxes, for each Share validly tendered and not properly withdrawn and accepted for payment pursuant to the Offer, subject to the conditions of the Offer. Procedures for tendering Shares are set forth in Section 4 (“Procedure for Tendering Shares”) of the Offer to Purchase.

If a shareholder wants to tender Shares in its account under the Direct Registration System (“DRS”), such shareholder must complete the box in the revised Letter of Transmittal entitled “Description of Shares Tendered” by (i) checking the box indicating that such Shares are held through DRS, (ii) providing such shareholder’s DRS number and (iii) indicating the number of Shares to be tendered by DRS.

SHARES PREVIOUSLY VALIDLY TENDERED AND NOT PROPERLY WITHDRAWN CONSTITUTE VALID TENDERS FOR PURPOSES OF THE OFFER. SHAREHOLDERS ARE NOT REQUIRED TO TAKE ANY FURTHER ACTION WITH RESPECT TO SUCH SHARES IN ORDER TO RECEIVE THE INCREASED OFFER PRICE IF SHARES ARE ACCEPTED FOR PAYMENT AND PAID FOR BY PURCHASER PURSUANT TO THE OFFER, EXCEPT AS MAY BE REQUIRED BY THE GUARANTEED DELIVERY PROCEDURE IF SUCH PROCEDURE IS UTILIZED.

4. Material U.S. Federal Income Tax Consequences.

The first two paragraphs under Section 6 (“Certain U.S. Federal Income Tax Consequences”) of the Offer to Purchase are hereby amended and restated in their entirety as follows:

The following is a summary of material U.S. federal income tax consequences of the Offer and the Proposed Merger to shareholders of the Company whose Shares are tendered and accepted for payment pursuant to the Offer, or whose Shares are converted into the right to receive Merger Consideration in the Proposed Merger. The summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), applicable Treasury Regulations, and administrative and judicial interpretations thereof, all as in effect as of the date of this Supplement and all of which may change, possibly with retroactive effect. The summary does not purport to address all of the tax consequences that may be relevant to particular shareholders in light of their personal circumstances. The summary applies only to shareholders that hold their shares as capital assets and may not apply to shareholders subject to special rules under the Code, including, without limitation, persons who acquired their Shares upon the exercise of stock options or otherwise as compensation, banks or other financial institutions, brokers, dealers or traders in securities or commodities, insurance companies, partnerships or other flow-through entities, shareholders that mark-to-market their investment in their Shares, tax-exempt entities, persons that are subject to alternative minimum tax, persons that hold Shares as a position in a “straddle” or as part of a “hedging,” “conversion” or “constructive sale” transaction or other integrated investment, or persons that have a functional currency other than the U.S. dollar. This summary does not discuss the U.S. federal income tax consequences to any shareholder of the Company that, for U.S. federal income tax purposes, is a non-resident

10

alien individual, foreign corporation, foreign partnership or foreign estate or trust, and does not address any state, local or foreign tax consequences of the Offer or the Proposed Merger. This summary assumes that the Offer and the Proposed Merger are completed as described in the Offer to Purchase, as amended and supplemented by this Supplement, and that all conditions to closing the Offer and the Proposed Merger as set forth in this Supplement are satisfied without waiver.

THIS SUMMARY IS NOT INTENDED TO BE, AND SHOULD NOT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY PARTICULAR SHAREHOLDER. BECAUSE INDIVIDUAL CIRCUMSTANCES MAY DIFFER, EACH SHAREHOLDER SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING THE PARTICULAR TAX EFFECTS TO SUCH SHAREHOLDER OF THE OFFER AND THE PROPOSED MERGER, INCLUDING THE SPECIFIC APPLICATION AND EFFECT TO IT OF U.S. FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS AND THE APPLICABILITY OF ANY REPORTING REQUIREMENTS.

5. Price Range of Common Stock; Dividends.

The discussion set forth in Section 7 (“Price Range of Common Stock; Dividends”) of the Offer to Purchase is hereby amended and supplemented as follows:

The following table sets forth, for the periods indicated based on the Company’s fiscal year that ends on September 30, the reported high and low closing sales prices per Share of the Company’s common stock on the NASDAQ based on published financial sources.

	High		Low

WE URGE YOU TO OBTAIN CURRENT MARKET QUOTATIONS FOR THE SHARES.

6. Certain Information Concerning the Company.

The second paragraph under “Available Information” in Section 8 (“Certain Information Concerning the Company”) of the Offer to Purchase is hereby amended and restated in its entirety as follows:

Except as otherwise provided in the Offer to Purchase and this Supplement, the information concerning the Company contained herein has been taken from or is based upon reports and other documents on file with the Securities and Exchange Commission (the “SEC”) or otherwise publicly available. Although we have no knowledge which would indicate that any statements contained herein based upon such reports and documents are untrue, the Company is responsible for the accuracy or completeness of the information contained in such reports and other documents and any failure by the Company to disclose events that may have occurred may affect the significance or accuracy of any such information.

7. Certain Information Concerning Purchaser and Omnicare

The discussion in Section 9 (“Certain Information Concerning Purchaser and Omnicare”) of the Offer to Purchase is hereby amended and supplemented as follows:

As of the date of this Supplement, Omnicare beneficially owns 100 Shares, representing less than 1% of the outstanding Shares. Omnicare has not effected any transactions in Shares during the past 60 days.

The summary consolidated financial data set forth below for each of the fiscal years ended December 31, 2004 and December 31, 2003 have been derived from Omnicare’s audited consolidated financial statements, which are incorporated herein by reference to Item 8 of Omnicare’s Annual Report on Form 10-K for the fiscal year ended December 31, 2004, filed with the SEC on March 16, 2005. The summary consolidated financial data for the three months ended March 31, 2005 and March 31, 2004 have been derived from Omnicare’s unaudited consolidated interim financial statements, which are incorporated herein by reference to Part I of Omnicare’s Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2005, filed with the SEC on May 10, 2005.

(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 ratio of earnings to fixed charges has been computed by adding income before taxes and fixed charges to derive adjusted income, and dividing adjusted income by fixed charges. Fixed charges consist of interest expense on debt (including the amortization of debt expense) and one-third (the proportion deemed representative of the interest portion) of rent expense.

8. Source and Amount of Funds.

The discussion set forth in Section 10 (“Source and Amount of Funds”) of the Offer to Purchase is hereby amended and supplemented as follows:

The Offer is conditioned upon receipt by Omnicare of the proceeds of the financings contemplated by its Commitment Letter, as amended, or such other financings that are sufficient, together with cash on hand, to consummate the Offer and the Proposed Merger and to refinance all debt of the Company and Omnicare that is or could be required to be repurchased or becomes, or could be declared, due and payable as a result of the Offer or the Proposed Merger or the financing thereof and to pay all related fees and expenses. As a result of the increase in the Offer price, we will need approximately $1.5 billion to purchase all of the outstanding Shares (assuming the exercise of all outstanding stock options) pursuant to the Offer and to pay related fees and expenses. In addition, we currently intend, after the proposed merger with Omnicare to purchase the Company’s 6.875% senior subordinated notes due 2013 ($250 million aggregate principal amount as of March 31, 2005). Omnicare has made no alternative financing arrangements or alternative financing plans.

On April 28, 2005, Omnicare amended its original Commitment Letter (the “Commitment Letter Amendment”) with the Commitment Parties to extend the expiration date of the commitment thereunder to June 30, 2005.

On June 16, 2005, Omnicare further amended the Commitment Letter (“Commitment Letter Amendment No. 2”) (i) to increase the revolving credit facility and the 364-day facility as noted below, (ii) to extend the expiration date of the commitments thereunder to December 30, 2005, and (iii) to decrease the applicable interest rate margins on borrowings (to ranges from 0.50% to 1.75%) and the fees on commitments (to ranges from 0.125% to 0.375%). Such amendment also provides that the Commitment Parties’ commitments to provide the Credit Facilities are subject to, among other things, the non-occurrence since December 31, 2004 of any material adverse change in the business, operations, property or financial condition of Omnicare and its subsidiaries taken as a whole, or of the Company and its subsidiaries taken as a whole. Commitment Letter Amendment No. 2 provides for senior bank financing under the Credit Facilities to Omnicare in the aggregate amount of $2.75 billion. The Credit Facilities will be comprised of:

— a $800 million revolving credit facility, with one sub-facility for letter of credit and one sub-facility for swing line loans, each in the amount of up to $50 million maturing five years after the initial funding date (the “Closing Date”);

13

— a $700.0 million senior term loan facility maturing five years after the Closing Date; and

— a $1.25 billion 364-day facility maturing 364 days after the Closing Date.

Other than as noted above, the material terms and conditions described in the Offer to Purchase with respect to the Commitment Letter and the Credit Facilities remain in effect.

The foregoing descriptions of the Commitment Letter, the Commitment Letter Amendment, Commitment Letter Amendment No. 2 and the Credit Facilities are qualified in their entirety by reference to the Commitment Letter, the Commitment Letter Amendment and Commitment Letter Amendment No. 2, copies of which are filed as Exhibit (b)(1), (b)(2) and (b)(3), respectively, to the Schedule TO.

9. Background of the Offer.

The discussion set forth in Section 11 (“Background of the Offer”) of the Offer to Purchase is hereby amended and supplemented as follows:

The following paragraph is inserted before the paragraph that begins “On March 2, 2004”:

In late February 2004, the Omnicare board of directors met and discussed, among other things, a proposed business combination involving Omnicare and NeighborCare. After consultation with Omnicare management and Omnicare’s legal and financial advisors, and based upon publicly available information for NeighborCare, the Omnicare board of directors authorized Mr. Gemunder to propose a business combination to Mr. Arlotta in which NeighborCare shareholders would receive $30.00 per share in a combination of cash and Omnicare common stock.

The following paragraph is inserted before the paragraph that begins “On June 3, 2004”:

Omnicare determined to make an all-cash offer for NeighborCare’s Common Stock (i) because the NeighborCare board of directors already had indicated that it had “no interest in pursuing” Omnicare’s prior proposal, which contemplated that NeighborCare shareholders would receive cash and Omnicare common stock, (ii) to make clear that Omnicare was offering $30.00 in value for each share of NeighborCare and (iii) to avoid, particularly in the context of a proposal that the NeighborCare board was unwilling to consider or even to discuss, any challenge to the value of Omnicare’s Offer (given that, if NeighborCare would agree to entertain Omnicare’s earlier proposal, a portion of the consideration would be paid in Omnicare common stock).

The following paragraphs are to be added to the end of such section:

On June 4, 2004, the Company filed a Solicitation/Recommendation Statement on Schedule 14D-9 (the ”Schedule 14D-9”) confirming it had received a letter from Omnicare stating its intention to commence the Offer.

On June 4, 2004, Omnicare filed a Notification and Report Form with respect to the Offer and the Proposed Merger with the Antitrust Division of the FTC.

On June 14, 2004, the Company mailed a letter to shareholders and filed a Schedule 14D-9 announcing that the Company’s board of directors had recommended that the Company’s shareholders reject Omnicare’s offer. Omnicare issued a press release, later that day, restating the benefits of the transaction and that Omnicare continued to be willing to discuss with the Company all aspects of the Offer.

14

On June 15, 2004, Omnicare issued the following press release:

OMNICARE SAYS NEIGHBORCARE SHAREHOLDERS DESERVE

STRAIGHTFORWARD ANSWERS AT TODAY’S ANNUAL MEETING

COVINGTON, Ky., June 15, 2004 – Omnicare, Inc. (NYSE: OCR) today placed an advertisement in The Baltimore Sun regarding its offer to acquire all of NeighborCare’s (NASDAQ: NCRX) outstanding common stock for $30.00 per share in cash. The text of the advertisement is as follows:

An Important Message From Omnicare:

NEIGHBORCARE SHAREHOLDERS DESERVE

STRAIGHTFORWARD ANSWERS AT TODAY’S ANNUAL MEETING

1. Why has NeighborCare’s Board repeatedly refused to discuss all aspects of Omnicare’s $30 per share all-cash offer?

2. Why should NeighborCare shareholders wait years for value, when Omnicare is offering premium value today?

NeighborCare just provided 2004 EPS guidance significantly below the existing analyst consensus.

After disappointing twice since May 12, how can shareholders expect NeighborCare to deliver on its new, highly aggressive and unrealistic projections?

3. Why did four out of five analysts reduce their 2004 EPS estimates and cut their median 12-month stock price targets from $26 to $23 following NeighborCare’s May 12 earnings announcement?¹

4. How can NeighborCare call Omnicare’s offer “opportunistic” when Omnicare maintained its original offer price of $30 per share despite the precipitous drop in NeighborCare’s stock price following its last earnings announcement?²

Omnicare’s offer provides NeighborCare shareholders with

a 70% premium, all-cash consideration, no market risk,

no execution risk and immediate certainty of value.

The choice is clear. Don’t forgo the opportunity to

realize maximum value now for your NeighborCare shares.

Send 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. Let the Board know that they are depriving you of value and should meet with Omnicare to discuss the offer. This combination is too compelling to ignore.

OMNICARE RAISES TENDER OFFER FOR

NEIGHBORCARE TO $32.00 PER SHARE IN CASH

COVINGTON, Ky., June 16, 2005 – Omnicare, Inc. (NYSE: OCR) today announced that it will increase its tender offer to purchase all of the outstanding common stock of NeighborCare, Inc. (NASDAQ: NCRX) to $32.00 per share in cash for a total transaction value of approximately $1.7 billion, which includes the assumption of NeighborCare’s net debt. The revised tender offer is scheduled to expire at 5:00 p.m., New York City time, on June 30, 2005, unless extended.

This increased offer price represents an 81% premium over NeighborCare’s closing stock price on May 21, 2004, the last trading day before Omnicare’s initial offer was made public on May 24, 2004, and a 50% premium over the 30-day average trading price of NeighborCare common stock prior to the public announcement of Omnicare’s initial offer.

“We continue to believe that the combination of Omnicare and NeighborCare will create a premier institutional pharmacy company and result in substantial benefits to both companies’ shareholders and other interested constituencies,” said Joel F. Gemunder, president and chief executive officer of Omnicare. “In light of our increased offer and the fact that we have satisfied the HSR condition to our offer, we look forward to sitting down with NeighborCare’s Board to discuss this compelling combination. Our increased all-cash offer of $32.00 per share provides certainty and premium value for NeighborCare’s shareholders.”

Omnicare noted that its Board fully supports this increased offer and that no further corporate action on the part of Omnicare is required to consummate the proposed transaction. In addition, Omnicare has commitments for financing that are sufficient to consummate the transaction.

Below is the complete text of a letter sent today from Joel F. Gemunder to the NeighborCare Board of Directors:

[LETTERHEAD OF OMNICARE, INC.]

June 16, 2005

BY FACSIMILE AND FEDEX

Board of Directors

NeighborCare, Inc.

601 East Pratt Street, 3rd Floor

Baltimore, Maryland 21202

Dear NeighborCare Board Members:

At 11:59 p.m. last evening, the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 applicable to Omnicare’s offer to acquire all of the outstanding shares of NeighborCare common stock expired. As you are aware, the expiration of the HSR waiting period satisfies one of the conditions to Omnicare’s offer and removes a significant hurdle to a combination of Omnicare and NeighborCare.

Omnicare is today announcing an increase in its cash offer for all of the outstanding shares of NeighborCare common stock to $32.00 per share in cash. This offer price represents an 81% premium over NeighborCare’s closing stock price on May 21, 2004, the last trading day before Omnicare’s initial offer was made public on May 24, 2004, and a 50% premium over the 30-day average trading price of NeighborCare common stock prior to the public announcement of Omnicare’s initial offer.

Omnicare’s increased offer represents a unique opportunity for NeighborCare shareholders to realize certainty and premium value today, especially when considering the following:

• Omnicare has increased its premium offer notwithstanding the fact that NeighborCare management has reduced 2005 EPS guidance by 31%.

• NeighborCare’s 2005 EPS guidance of $1.35-$1.60 established on June 14, 2004 in the wake of our premium offer was reduced 31% on May 4, 2005 to $1.02.

• NeighborCare is significantly underperforming the projections that management provided as a means to justify its standalone plan.

• Omnicare’s all-cash offer provides value that is clearly fair on any objective metric and eliminates business execution risk for your shareholders.

In light of the foregoing, you should give serious consideration to where NeighborCare’s stock would trade absent Omnicare’s offer.

As we have been saying for more than a year, a combination of Omnicare and NeighborCare is compelling and will result in substantial benefits to both companies’ shareholders and other interested constituencies. We continue to believe that this is the case, and we continue to be committed to an acquisition of NeighborCare. With the antitrust review behind us, we are increasing our offer now because we want to negotiate the other terms of a definitive agreement promptly.

As we have announced, we also intend to nominate three directors to the NeighborCare Board of Directors and solicit proxies from NeighborCare’s shareholders for the election of these nominees at your next annual meeting of shareholders. We would hope to avoid this process and negotiate the terms of a definitive agreement as promptly as practicable.

20

We and our advisors are prepared to meet with you and your advisors immediately to negotiate the terms of a definitive agreement. I look forward to hearing from you soon.

Sincerely,

/s/ JOEL F. GEMUNDER

Any determination by Omnicare or Purchaser concerning the events described in Section 11 (“Conditions to the Offer”) of this Supplement will be final and binding on all parties.

12. Certain Legal Matters; Regulatory Approvals.

The last sentence of the first paragraph under Section 16 (“Certain Legal Matters; Regulatory Approvals–State Takeover Laws”) of the Offer to Purchase is hereby amended and restated as follows:

Information regarding the Offer has been filed with the Pennsylvania Securities Commission (the “PSC”) in a Registration Statement pursuant to the Pennsylvania Takeover Disclosure Law and is available for inspection at the office of the PSC at Eastgate Office Building, Second Floor, 1010 North Seventh Street, Harrisburg, PA 17102-1410, during business hours.

The second paragraph under Section 16 (“Certain Legal Matters; Regulatory Approvals–Antitrust”) of the Offer to Purchase is hereby amended and restated in its entirety as follows:

On June 4, 2004, Omnicare filed a Notification and Report Form with respect to the Offer and the Proposed Merger with the Antitrust Division of the FTC. On June 25, 2004, Omnicare withdrew its Notification and Report Form with respect to the Offer and the Proposed Merger with the Antitrust Division of the FTC, and on June 28, 2004, Omnicare re-filed its Notification and Report Form to give the FTC additional time to review the transaction. As a result, the waiting period applicable to the purchase of Shares pursuant to the Offer was scheduled to expire at 11:59 p.m., New York City time, on or about July 13, 2004. On July 13, 2004, Omnicare received a request for additional information (a “Second Request”) from the FTC with respect to the Offer. Accordingly, the waiting period under the HSR was scheduled to expire ten days after Omnicare substantially complied with the Second Request or upon earlier termination by the FTC. On April 4, 2005, Omnicare

25

announced that on April 1, 2005 it had completed the submission of documents and data requested by the FTC under its Second Request under the HSR Act. Under its agreement with the FTC, Omnicare agreed not to seek to close a transaction with the Company before May 27, 2005. On May 3, 2005, Omnicare announced that it had agreed to provide more time to the FTC to review the documents and data submitted by Omnicare under the FTC’s Second Request under the HSR Act. Under its agreement with the FTC, Omnicare agreed not to seek to close a transaction with the Company until 12:01 a.m. on June 16, 2005.

At 11:59 p.m. on June 15, 2005, the waiting period under the HSR Act expired. Accordingly, the condition of the Offer relating to the expiration or termination of any applicable waiting period under applicable antitrust laws, including the HSR Act, has been satisfied.

13. Fees and Expenses.

The discussion set forth in Section 17 (“Fees and Expenses”) of the Offer to Purchase is hereby amended and restated in it entirety as follows:

Lazard Frères & Co. LLC (“Lazard”) and Lehman Brothers Inc.

Omnicare also has agreed to reimburse Lazard and Lehman Brothers for reasonable out-of-pocket expenses, including reasonable fees and expenses of their legal counsel, and to indemnify Lazard and Lehman Brothers and certain of their respective related parties against certain liabilities, including liabilities under the federal securities laws, in connection with their service as the Dealer Managers and financial advisors.

14. Miscellaneous.

The discussion set forth in Section 18 (“Miscellaneous”) of the Offer to Purchase is hereby amended and restated in its entirety as follows:

The Offer is not being made to, nor will tenders be accepted from or on behalf of, holders of Shares in any jurisdiction in which the making of the Offer or acceptance thereof would not be in compliance with the laws of such jurisdiction. However, we may, in our discretion, take such action as we may deem necessary to make the Offer in any such jurisdiction and extend the Offer to holders of Shares in such jurisdiction.

No person has been authorized to give any information or make any representation on behalf of Purchaser or Omnicare not contained in the Offer to Purchase, this Supplement or in the related revised Letter of Transmittal and, if given or made, such information or representation must not be relied upon as having been authorized.

EXCEPT AS OTHERWISE SET FORTH IN THIS SUPPLEMENT AND THE REVISED (GREEN) LETTER OF TRANSMITTAL, THE TERMS AND CONDITIONS PREVIOUSLY SET FORTH IN THE OFFER TO PURCHASE AND RELATED ORIGINAL (BLUE) LETTER OF TRANSMITTAL REMAIN APPLICABLE IN ALL RESPECTS TO THE OFFER.

Neither the delivery of this Supplement or the Offer to Purchase nor any purchase pursuant to the Offer shall, under any circumstances, create any implication that there has been no change in the affairs of Omnicare, Purchaser or the Company or any of their respective subsidiaries since the date as of which information is furnished or the date of this Supplement.

PLEASE READ ACCOMPANYING INSTRUCTIONS CAREFULLY.

Ladies and Gentlemen:

The undersigned hereby tenders to Nectarine Acquisition Corp., a Delaware corporation (“Purchaser”) and a wholly owned subsidiary of Omnicare, Inc., a Delaware corporation (“Omnicare”), the above-described Shares of the Company, pursuant to Purchaser’s offer to purchase all of the outstanding Shares at $32.00 per Share, net to the seller in cash, without interest, upon the terms and subject to the conditions set forth in the Offer to Purchase, as amended and supplemented by the Supplement to the Offer to Purchase, dated June 16, 2005 (the “Supplement”), receipt of which is hereby acknowledged, and in this revised Letter of Transmittal (which together, as each may be amended, supplemented or otherwise modified from time to time, constitute the “Offer”). We reserve the right to transfer or assign, in whole or from time to time in part, to one or more of our affiliates the right to purchase Shares tendered pursuant to the Offer, but any such transfer or assignment will not relieve us of our obligations under the Offer or prejudice your rights to receive payment for Shares validly tendered and accepted for payment.

Upon the terms and subject to the conditions of the Offer and effective upon acceptance for payment of and payment for the Shares, the undersigned hereby sells, assigns and transfers to, or upon the order of, Purchaser all right, title and interest in and to all of the Shares that are being tendered hereby (and any and all dividends, distributions, rights, other Shares or other securities issued or issuable in respect thereof on or after the date hereof (collectively, a “Distribution”)) and appoints the Depositary the true and lawful agent and attorney-in-fact of the undersigned with respect to such Shares (and any Distribution), with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to (i) deliver certificates for such Shares (and any Distribution), or transfer ownership of such Shares (and any Distribution) on the account books maintained by the Book-Entry Transfer Facility or other account books maintained with respect to the Direct Registration System, together, in any such case, with all accompanying evidences of transfer and authenticity, to or upon the order of Purchaser, (ii) present such Shares (and any Distribution) for transfer on the books of the Company and (iii) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares (and any Distribution), all in accordance with the terms of the Offer.

The undersigned hereby irrevocably appoints designees of Purchaser as the attorneys and proxies of the undersigned, each with full power of substitution, to exercise all voting and other rights of the undersigned in such manner as each such attorney and proxy or his substitute shall in his sole discretion deem proper, with respect to all of the Shares tendered hereby which have been accepted for payment by Purchaser prior to the time of any vote or other action (and any Distribution), at any meeting of shareholders of the Company (whether annual or special and whether or not an adjourned meeting), by written consent or otherwise. This proxy is irrevocable and is granted in consideration of, and is effective upon, the acceptance for payment of such Shares by Purchaser in accordance with the terms of the Offer. Such acceptance for payment shall revoke any other proxy or written consent granted by the undersigned at any time with respect to such Shares (and any Distribution), and no subsequent proxies will be given or written consents will be executed by the undersigned (and if given or executed, will not be deemed to be effective).

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Shares tendered hereby (and any Distribution) and that when the same are accepted for payment by Purchaser, Purchaser will acquire good and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claims. The undersigned will, upon request, execute and deliver any additional documents deemed by the Depositary or Purchaser to be necessary or desirable to complete the sale, assignment and transfer of the Shares tendered hereby (and any Distribution).

All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned, and any obligation of the undersigned hereunder shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned. Except as stated in the Offer, this tender is irrevocable.

3

The undersigned understands that tenders of Shares pursuant to any one of the procedures described in Section 4 (“Procedure for Tendering Shares”) of the Offer to Purchase and in the instructions hereto will constitute an agreement between the undersigned and Purchaser upon the terms and subject to the conditions of the Offer.

Unless otherwise indicated under “Special Payment Instructions,” please issue the check for the purchase price of any Share Certificates (as defined in the Offer to Purchase), and return any Shares not tendered or not purchased, in the name(s) of the undersigned (and, (a) in the case of Shares tendered by book-entry transfer, by credit to the account at the Book-Entry Transfer Facility and (b) by credit in connection with the Direct Registration System that are not accepted for payment by crediting the account with the Direct Registration System). Similarly, unless otherwise indicated under “Special Delivery Instructions,” please mail the check for the purchase price of any Share Certificates purchased and any certificates for Shares not tendered or not purchased (and accompanying documents, as appropriate) to the undersigned at the address shown below the undersigned’s signature(s). In the event that both “Special Payment Instructions” and “Special Delivery Instructions” are completed, please issue the check for the purchase price of any Share Certificates purchased and return any Shares not tendered or not purchased in the name(s) of, and mail said check and any certificates to, the person(s) so indicated. The undersigned recognizes that Purchaser has no obligation, pursuant to the “Special Payment Instructions,” to transfer any Shares from the name of the registered holder(s) thereof if Purchaser does not accept for payment any of the Shares so tendered.

INSTRUCTIONS

FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

1.    Guarantee of Signatures.    Except as otherwise provided below, all signatures on this revised Letter of Transmittal must be guaranteed by a financial institution (including most banks, savings and loan associations and brokerage houses) that is a member of a recognized Medallion Program approved by The Securities Transfer Association, Inc. or any other “eligible guarantor institution” (as such term is defined in Rule 17Ad-15 under the Securities Exchange Act of 1934, as amended) (each an “Eligible Institution”). Signatures on this revised Letter of Transmittal need not be guaranteed (i) if this revised Letter of Transmittal is signed by the registered holder(s) of the Shares (which term, for purposes of this document, shall include any participant in the Book-Entry Transfer Facility whose name appears on a security position listing as the owner of Shares) tendered herewith and such holder(s) have not completed the instruction entitled “Special Payment Instructions” on this revised Letter of Transmittal or (ii) if such Shares are tendered for the account of an Eligible Institution. See Instruction 5.

2.    Delivery of Revised Letter of Transmittal and Shares.    This revised Letter of Transmittal is to be used if Share Certificates are to be forwarded herewith or, unless an Agent’s Message is utilized, if deliveries are to be made by book-entry transfer pursuant to the procedures set forth in Section 4 (“Procedure for Tendering Shares”) of the Offer to Purchase. Share Certificates for all physically delivered Shares, or a confirmation of a book-entry transfer into the Depositary’s account at the Book-Entry Transfer Facility of all Shares delivered electronically, as well as a properly completed and duly executed revised Letter of Transmittal (or a manually signed facsimile thereof) and any other documents required by this revised Letter of Transmittal, or an Agent’s Message in the case of a book-entry transfer, must be received by the Depositary at one of its addresses set forth on the front page of this revised Letter of Transmittal by the Expiration Date (as defined in the Supplement). Shareholders whose Share Certificates are not immediately available, who cannot deliver their Share Certificates and all other required documents to the Depositary prior to the Expiration Date or who cannot complete the procedure for delivery by book-entry transfer on a timely basis, may tender their Shares pursuant to the guaranteed delivery procedure described in Section 4 (“Procedure for Tendering Shares”) of the Offer to Purchase. Pursuant to such procedure: (i) such tender must be made by or through an Eligible Institution; (ii) a properly completed and duly executed revised Notice of Guaranteed Delivery, substantially in the form provided by Purchaser, must be received by the Depositary prior to the Expiration Date; and (iii) Share Certificates for all tendered Shares, in proper form for tender, or a confirmation of a book-entry transfer into the Depositary’s account at the Book-Entry Transfer Facility of all Shares delivered electronically, as well as a properly completed and duly executed revised Letter of Transmittal (or a manually signed facsimile thereof), and any other documents required by this revised Letter of Transmittal, must be received by the Depositary within three business days of the date of execution of such revised Notice of Guaranteed Delivery, as provided in Section 4 (“Procedure for Tendering Shares”) of the Offer to Purchase.

THE METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING SHAREHOLDER. IF CERTIFICATES FOR SHARES ARE SENT BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.

NO ALTERNATIVE, CONDITIONAL OR CONTINGENT TENDERS WILL BE ACCEPTED, AND NO FRACTIONAL SHARES WILL BE PURCHASED. BY EXECUTING THIS REVISED LETTER OF TRANSMITTAL, THE TENDERING SHAREHOLDER WAIVES ANY RIGHT TO RECEIVE ANY NOTICE OF THE ACCEPTANCE FOR PAYMENT OF THE SHARES.

3.    Inadequate Space.    If the space provided herein is inadequate, the Share Certificate numbers, the number of Shares evidenced by such Share Certificates and the number of Shares tendered should be listed on a separate signed schedule and attached hereto.

4.    Partial Tenders (not applicable to shareholders who tender by book-entry transfer or hold through the Direct Registration System).    If fewer than all the Shares represented by any certificate delivered to the Depositary are to be tendered, fill in the number of Shares which are to be tendered in the box entitled “Number

6

of Shares Tendered.” In such case, a new certificate for the remainder of the Shares represented by the old certificate will be sent to the person(s) signing this revised Letter of Transmittal, unless otherwise provided in the appropriate box on this revised Letter of Transmittal, as promptly as practicable following the expiration or termination of the Offer. All Shares represented by certificates delivered to the Depositary will be deemed to have been tendered unless otherwise indicated.

5.    Signatures on Revised Letter of Transmittal; Stock Powers and Endorsements.    If this revised Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, the signature(s) must correspond with the name(s) as written on the face of the certificates without alteration, enlargement or any change whatsoever.

If any of the Shares tendered hereby are held of record by two or more persons, all such persons must sign this revised Letter of Transmittal.

If any of the Shares tendered hereby are registered in different names on different certificates, it will be necessary to complete, sign and submit as many separate revised Letters of Transmittal as there are different registrations of certificates.

If this revised Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, no endorsements of certificates or separate stock powers are required unless payment of the purchase price is to be made, or Shares not tendered or not purchased are to be returned, in the name of any person other than the registered holder(s). Signatures on any such certificates or stock powers must be guaranteed by an Eligible Institution.

If this revised Letter of Transmittal is signed by a person other than the registered holder(s) of the Shares tendered hereby, certificates must be endorsed or accompanied by appropriate stock powers, in either case, signed exactly as the name(s) of the registered holder(s) appear(s) on the certificates for such Shares. Signature(s) on any such certificates or stock powers must be guaranteed by an Eligible Institution.

If this revised Letter of Transmittal or any certificate or stock power is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or other person acting in a fiduciary or representative capacity, such person should so indicate when signing, and proper evidence satisfactory to Purchaser of the authority of such person so to act must be submitted.

6.    Stock Transfer Taxes.    Purchaser will pay any stock transfer taxes with respect to the sale and transfer of any Shares to it or its order pursuant to the Offer. If, however, payment of the purchase price is to be made to, or Shares not tendered or not purchased are to be returned in the name of, any person other than the registered holder(s), or if a transfer tax is imposed for any reason other than the sale or transfer of Shares to Purchaser pursuant to the Offer, then the amount of any stock transfer taxes (whether imposed on the registered holder(s), such other person or otherwise) will be deducted from the purchase price unless satisfactory evidence of the payment of such taxes, or exemption therefrom, is submitted herewith.

7.    Special Payment and Delivery Instructions.    If the check for the purchase price of any Shares purchased is to be issued, or any Shares not tendered or not purchased are to be returned, in the name of a person other than the person(s) signing this revised Letter of Transmittal or if the check or any certificates for Shares not tendered or not purchased are to be mailed to someone other than the person(s) signing this revised Letter of Transmittal or to the person(s) signing this revised Letter of Transmittal at an address other than that shown above, the appropriate boxes on this revised Letter of Transmittal should be completed. Shareholders tendering Shares by book-entry transfer may request that Shares not purchased be credited to such account at the Book-Entry Transfer Facility as such shareholder may designate under “Special Payment Instructions.” If no such instructions are given, any such Shares not purchased will be returned by crediting the account at the Book-Entry Transfer Facility designated above.

8.    Substitute Form W-9.    Under current U.S. federal tax law, the Depositary may be required to withhold and pay over to the Internal Revenue Service (“IRS”) a portion of payments made to certain shareholders or other payees pursuant to the Offer. In order to avoid such backup withholding, each tendering shareholder and other payee must provide the Depositary with its correct taxpayer identification number (“TIN”) and certify that it is

7

not subject to such backup withholding by completing the enclosed Substitute Form W-9. In general, for an individual, the TIN is the Social Security Number of such individual. If the Depositary is not provided with the correct TIN, the shareholder or other payee may be subject to a penalty imposed by the IRS, and any reportable payments to such person may be subject to backup withholding at the applicable rate (currently 28%). Reportable payments will be subject to information reporting, even if the Depositary is provided with a TIN. For further information concerning backup withholding and instructions for completing the Substitute Form W-9 (including how to obtain a TIN if you do not have one and how to complete the Substitute Form W-9 if Shares are held in more than one name), consult the enclosed “Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9.”

Certain persons (including, among others, corporations and certain non-U.S. individuals and entities) are not subject to these backup withholding and reporting requirements. Exempt persons should indicate their exempt status on the Substitute Form W-9. To satisfy the Depositary that a non-U.S. person qualifies as an exempt recipient, such person must submit a properly completed IRS Form W-8BEN, signed under penalties of perjury, attesting to that person’s exempt status. Such Forms can be obtained from the Depositary.

Failure to complete the Substitute Form W-9 will not, by itself, cause Shares to be deemed invalidly tendered, but may require the Depositary to withhold a portion of payments made pursuant to the Offer. Backup withholding is not an additional federal income tax. Rather, the federal income tax liability of a person subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is furnished to the IRS. NOTE: FAILURE TO COMPLETE AND RETURN THE SUBSTITUTE FORM W-9 MAY RESULT IN BACKUP WITHHOLDING OF A PORTION OF PAYMENTS MADE TO YOU PURSUANT TO THE OFFER. PLEASE REVIEW THE ENCLOSED “GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER ON SUBSTITUTE FORM W-9” FOR ADDITIONAL DETAILS.

9.    Mutilated, Lost, Stolen or Destroyed Certificates.    Any holder of a Share Certificate(s) whose Share Certificate(s) has been mutilated, lost, stolen, or destroyed should (i) complete this revised Letter of Transmittal and check the appropriate box above and (ii) contact the Company’s transfer agent, StockTrans, Inc. immediately by calling (800) 733-1121. StockTrans, Inc. will provide such holder with all necessary forms and instructions to replace any mutilated, lost, stolen or destroyed certificates. The holder may also be required to give the Company a bond as indemnity against any claim that may be made against it with respect to the certificate(s) alleged to have been mutilated, lost, stolen, or destroyed. However, there can be no assurances that such mutilated, lost, stolen or destroyed certificates will be replaced prior to the Expiration Date.

10.    Waiver of Conditions.    The conditions of the Offer may be waived, in whole or in part, by Purchaser, in its sole discretion, at any time and from time to time, in the case of any shares tendered.

11.    Requests for Assistance or Additional Copies.    Questions or requests for assistance may be directed to the Information Agent or the Dealer Managers at their respective addresses and telephone numbers set forth below. Additional copies of the Offer to Purchase, the Supplement, this revised Letter of Transmittal and the revised Notice of Guaranteed Delivery may be obtained from the Information Agent at its address and telephone numbers set forth below. Holders of Shares may also contact their broker, dealer, commercial bank or trust company or other nominee for assistance concerning the Offer.

12.    Shares Held in the Direct Registration System.    If a shareholder wants to tender Shares in its account under the Direct Registration System (“DRS”), such shareholder must complete the box in the revised Letter of Transmittal entitled “Description of Shares Tendered” by (i) checking the box indicating that your Shares are held through DRS, (ii) providing your DRS number and (iii) indicating the number of Shares to be tendered by DRS.

Privacy Act Notice—Section 6109 requires most recipients of dividend, interest, and other payments to give their correct TIN to payers who must report the payments to the IRS.

The IRS may also disclose this information to other countries under a tax treaty, or to Federal and state agencies to enforce Federal nontax criminal laws and to combat terrorism. Payees must provide their TINs whether or not they are required to file tax returns. Payers must generally withhold a certain percentage (currently 28%) of taxable interest, dividend, and certain other payments to a payee who does not give a TIN to a payer. Certain penalties may also apply.

Penalties

(1)  Penalty For Failure to Furnish TIN.—If you fail to furnish your TIN to a requester, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

(2)  Civil Penalty for False Information with Respect to Withholding.—If you make a false statement with no reasonable basis which results in no backup withholding, you are subject to a penalty of $500.

(3)  Criminal Penalty for Falsifying Information.—Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

(4)  Misuse of TINs.—If the requester discloses or uses TINs in violation of federal law, the requester may be subject to civil and criminal penalties.

OMNICARE ANNOUNCES EXPIRATION OF

HART-SCOTT-RODINO WAITING PERIOD

Federal Regulators Will Not Object to Proposed Acquisition of NeighborCare

COVINGTON, Ky., June 16, 2005 - Omnicare, Inc. (NYSE: OCR) today announced that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (HSR) has expired, indicating that federal regulators will not object to Omnicare’s proposed acquisition of NeighborCare, Inc. (NASDAQ: NCRX) and the removal of a major condition to the offer.

About Omnicare, Inc.

Certain factors that could cause actual events not to occur as expressed in the forward-looking statements include, but are not limited to, the inability to integrate the NeighborCare acquisition as anticipated; the inability to realize expected revenues, earnings, synergies and other benefits from the NeighborCare acquisition; the performance of Omnicare’s institutional pharmacy business; business conditions in the institutional pharmacy industry generally; the inability to expand geographically as anticipated; the inability to leverage services and capabilities among Omnicare’s network of institutional pharmacies as anticipated; the effectiveness of Omnicare’s strategy in the institutional pharmacy business; and the ability of the NeighborCare acquisition to

OMNICARE RAISES TENDER OFFER FOR

NEIGHBORCARE TO $32.00 PER SHARE IN CASH

COVINGTON, Ky., June 16, 2005 - Omnicare, Inc. (NYSE: OCR) today announced that it will increase its tender offer to purchase all of the outstanding common stock of NeighborCare, Inc. (NASDAQ: NCRX) to $32.00 per share in cash for a total transaction value of approximately $1.7 billion, which includes the assumption of NeighborCare’s net debt. The revised tender offer is scheduled to expire at 5:00 p.m., New York City time, on June 30, 2005, unless extended.

This increased offer price represents an 81% premium over NeighborCare’s closing stock price on May 21, 2004, the last trading day before Omnicare’s initial offer was made public on May 24, 2004, and a 50% premium over the 30-day average trading price of NeighborCare common stock prior to the public announcement of Omnicare’s initial offer.

“We continue to believe that the combination of Omnicare and NeighborCare will create a premier institutional pharmacy company and result in substantial benefits to both companies’ shareholders and other interested constituencies,” said Joel F. Gemunder, president and chief executive officer of Omnicare. “In light of our increased offer and the fact that we have satisfied the HSR condition to our offer, we look forward to sitting down with NeighborCare’s Board to discuss this compelling combination. Our increased all-cash offer of $32.00 per share provides certainty and premium value for NeighborCare’s shareholders.”

Omnicare noted that its Board fully supports this increased offer and that no further corporate action on the part of Omnicare is required to consummate the proposed transaction. In addition, Omnicare has commitments for financing that are sufficient to consummate the transaction.

Below is the complete text of a letter sent today from Joel F. Gemunder to the NeighborCare Board of Directors:

[LETTERHEAD OF OMNICARE, INC.]

June 16, 2005

BY FACSIMILE AND FEDEX

Board of Directors

NeighborCare, Inc.

601 East Pratt Street, 3^rd Floor

Baltimore, Maryland 21202

Dear NeighborCare Board Members:

At 11:59 p.m. last evening, the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 applicable to Omnicare’s offer to acquire all of the outstanding shares of NeighborCare common stock expired. As you are aware, the expiration of the HSR waiting period satisfies one of the conditions to Omnicare’s offer and removes a significant hurdle to a combination of Omnicare and NeighborCare.

Omnicare is today announcing an increase in its cash offer for all of the outstanding shares of NeighborCare common stock to $32.00 per share in cash. This offer price represents an 81% premium over NeighborCare’s closing stock price on May 21, 2004, the last trading day before Omnicare’s initial offer was made public on May 24, 2004, and a 50% premium over the 30-day average trading price of NeighborCare common stock prior to the public announcement of Omnicare’s initial offer.

Omnicare’s increased offer represents a unique opportunity for NeighborCare shareholders to realize certainty and premium value today, especially when considering the following:

• Omnicare has increased its premium offer notwithstanding the fact that NeighborCare management has reduced 2005 EPS guidance by 31%.

• NeighborCare’s 2005 EPS guidance of $1.35-$1.60 established on June 14, 2004 in the wake of our premium offer was reduced 31% on May 4, 2005 to $1.02.

• NeighborCare is significantly underperforming the projections that management provided as a means to justify its standalone plan.

• Omnicare’s all-cash offer provides value that is clearly fair on any objective metric and eliminates business execution risk for your shareholders.

In light of the foregoing, you should give serious consideration to where NeighborCare’s stock would trade absent Omnicare’s offer.

As we have been saying for more than a year, a combination of Omnicare and NeighborCare is compelling and will result in substantial benefits to both companies’ shareholders and other interested constituencies. We continue to believe that this is the case, and we continue to be committed to an acquisition of NeighborCare. With the antitrust review behind us, we are increasing our offer now because we want to negotiate the other terms of a definitive agreement promptly.

As we have announced, we also intend to nominate three directors to the NeighborCare Board of Directors and solicit proxies from NeighborCare’s shareholders for the election of these nominees at your next annual meeting of shareholders. We would hope to avoid this process and negotiate the terms of a definitive agreement as promptly as practicable.

We and our advisors are prepared to meet with you and your advisors immediately to negotiate the terms of a definitive agreement. I look forward to hearing from you soon.

Sincerely,

/s/ JOEL F. GEMUNDER
