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 $30.00 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 offer to purchase and the related 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 offer to purchase and the related letter of transmittal.

Who is offering to buy my securities? Why?

Omnicare, Inc. is offering to purchase all of the outstanding shares of common stock, including the associated preferred stock purchase rights, of NeighborCare, Inc., at a price of $30.00 per share, net to the seller in cash, without interest. Omnicare is a Delaware corporation and is making the offer through its wholly owned subsidiary, Nectarine Acquisition Corp., a Delaware corporation, which was formed solely for the purpose of making this tender offer for all of the outstanding shares of common stock, including the associated preferred stock purchase rights, of NeighborCare. The tender offer is the first step in our plan to acquire all of the outstanding shares of NeighborCare. We intend, promptly after completion of the offer, to seek to have NeighborCare consummate a merger of our wholly owned subsidiary with and into NeighborCare, in which each remaining share of NeighborCare that is not owned by us would be converted according to the terms of our proposed merger into the right to receive an amount in cash equal to the per share price paid in the offer, without interest.

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 offer to purchase, Omnicare beneficially owns 100 shares of the common stock of NeighborCare. NeighborCare’s recent public disclosure provided that, as of May 11, 2004, there were 43,672,753 shares of common stock outstanding (exclusive of the 100 shares owned by Omnicare) and 259,980 shares to be issued in connection with NeighborCare’s joint plan of reorganization confirmed by the Bankruptcy Court on September 20, 2001. The number of outstanding shares is contained in the Quarterly Report on Form 10-Q filed by NeighborCare on May 14, 2004. In addition, during NeighborCare’s second quarter 2004 earnings call on May 13, 2004, NeighborCare disclosed that there were 2,281,904 shares reserved for issuance upon the exercise of outstanding options to purchase shares.

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 $30.00 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.

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 to provide such new debt financing from

1

JPMorgan Chase Bank, 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 (collectively, the “Commitment Parties”), pursuant to which, subject to specified conditions, the Commitment Parties have agreed to provide to Omnicare $2.4 billion (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 $1.4 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 “The Offer—Source and Amount of Funds.”

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 its existing commitment letter 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 the commitment letter, we cannot guarantee that Omnicare will be able to obtain the financings contemplated by the commitment letter. You should consider all of the information concerning the financial condition of Omnicare included or incorporated by reference into this Offer to Purchase before deciding to tender shares in our offer. See “The Offer—Certain Information Concerning Purchaser and Omnicare—Available Information.”

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 are prepared to discuss with NeighborCare all aspects of our proposal to acquire NeighborCare. See “The Offer—Background of the Offer.”

What are the associated preferred stock purchase rights?

The preferred stock purchase rights were created pursuant to the implementation of NeighborCare’s “poison pill” in 2003, but currently are not represented by separate certificates. Instead, they are represented by the certificates for your shares. Presently, each such certificate represents not only shares of common stock but also the corresponding right to purchase, at a price of $100 per share (subject to adjustment), one one-hundredth of a share of Series B Preferred Stock per share of common stock represented by such certificate. The right to purchase such preferred stock is not exercisable until a “distribution” of such rights occurs. Unless NeighborCare’s board of directors elects to redeem the poison pill and, thus, terminate the preferred stock purchase rights or amends the poison pill to postpone the distribution of such rights, this offer will likely result in a distribution of the preferred stock purchase rights ten business days following the commencement of this offer with no further action from any party.

2

In the event of a distribution, under the terms of the poison pill, Omnicare, Purchaser and their affiliates will not be entitled to any preferred stock purchase rights. Due to this fact, NeighborCare’s poison pill and the preferred stock purchase rights would, unless the rights are promptly redeemed by NeighborCare’s board of directors, serve to impede and perhaps frustrate Purchaser’s attempt to merge with NeighborCare following the consummation of this offer. Unless a distribution occurs, a tender of shares will include a tender of the associated preferred stock purchase rights. If a distribution does occur, you will need to tender one right with each share tendered. We will not pay any additional consideration for the tender of a preferred stock purchase right. See “The Offer—Procedure for Tendering Shares,” “—Certain Information Concerning the Company” and “—Conditions to the Offer.”

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 July 7, 2004, 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, which is described in “The Offer—Procedure for Tendering Shares.”

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 “The Offer—Conditions to the Offer” 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 “The Offer—Terms of the Offer; Expiration Date.”

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 (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;

3

— All waiting periods under applicable antitrust laws, including the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, having expired or been terminated;

— 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;

— Omnicare having available to it proceeds of the financings contemplated by its existing commitment letter 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 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 expected 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 “The Offer—Conditions to the Offer.”

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 “The Offer—Procedures for Tendering Shares.”

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 August 2, 2004, 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 “The Offer—Withdrawal Rights.”

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 “The Offer—Withdrawal Rights.”

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

4

conditions to the offer, as set forth in “The Offer—Conditions to the Offer.” 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 “The Offer—Procedure for Tendering Shares”) and a properly completed and duly executed 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. 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 Securities and Exchange Commission (the “SEC”) or otherwise cease being subject to the SEC rules relating to publicly held companies.

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 Pennsylvania Business Corporation Law. If you elect to dissent in circumstances in which dissenters’ rights are applicable and comply with the provisions of the Pennsylvania Business Corporation Law 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 Pennsylvania Business Corporation Law. Your right to seek an appraisal under Pennsylvania law will be forfeited if you do not comply with the requirements of the Pennsylvania Business Corporation Law relating to dissenters’ rights. See “The Offer—Certain Legal Matters; Regulatory Approvals.”

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

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 a share 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.

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) 632-6719 or (212) 526-7850, respectively.

(the “Company”), at a price of $30.00 per Share, net to the seller in cash, without interest, upon the terms and subject to the conditions set forth in this Offer to Purchase and in the related Letter of Transmittal (which together, as amended, supplemented or otherwise modified from time to time, constitute the “Offer”).

Shareholders will be required to tender one Right for each Share tendered in order to effect a valid tender of Shares in accordance with the procedures set forth in “The Offer—Procedure for Tendering Shares.” A tender of Shares will also constitute a tender of the associated Rights.

If you tender your Shares to us in the Offer, you will not be obligated to pay brokerage fees, commissions or, except as set forth in Instruction 6 of the Letter of Transmittal, transfer taxes on the sale of your Shares pursuant to the Offer. If you own your Shares through a broker or other nominee, and your broker tenders 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 such charges will apply. We will pay all charges and expenses of Lazard Frères & Co. LLC and Lehman Brothers Inc. (the “Dealer Managers”), The Bank of New York (the “Depositary”) and Innisfree M&A Incorporated (the “Information Agent”) incurred in connection with the Offer. See “The Offer—Fees and Expenses.”

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 (the “Effective Time”), 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 (the “Merger Consideration”).

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 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

6

OF CHAPTER 25 OF 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 THE COMPANY AND OMNICARE (THE “SUBCHAPTER 25F CONDITION”), (3) ALL WAITING PERIODS UNDER APPLICABLE ANTITRUST LAWS, INCLUDING THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF 1976, AS AMENDED, HAVING EXPIRED OR BEEN TERMINATED, (4) 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”), (5) OMNICARE HAVING AVAILABLE TO IT PROCEEDS OF THE FINANCINGS CONTEMPLATED BY ITS EXISTING COMMITMENT LETTER 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 (6) 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 EXPECTED ECONOMIC VALUE TO OMNICARE OF THE ACQUISITION OF THE COMPANY (THE “IMPAIRMENT CONDITION”).

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 OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT INFORMATION, AND YOU SHOULD CAREFULLY READ BOTH IN THEIR ENTIRETY BEFORE YOU MAKE A DECISION WITH RESPECT TO THE OFFER.

THE OFFER

1. Terms of the Offer; Expiration Date.

On the terms and subject to the conditions set forth in this Offer (including, if the Offer is extended or amended, the terms and conditions of such extension or amendment), we will accept for payment and pay for all Shares that are validly tendered prior to the Expiration Date and not properly withdrawn.

“Expiration Date” means 5:00 p.m., New York City time, on July 7, 2004, unless we 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, (1) the Minimum Condition having been satisfied, (2) the Subchapter 25F Condition having been satisfied, (3) all waiting periods under applicable antitrust laws, including the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), having expired or been terminated, (4) the Rights Condition having been satisfied, (5) the Financing Condition having been satisfied and (6) the Impairment Condition having been satisfied. The Offer is also subject to other conditions as described in “The Offer—Conditions to the Offer.” If any of the conditions are not satisfied, we may: (i) terminate the Offer and return all tendered Shares; (ii) extend the Offer and, subject to certain conditions and to your withdrawal rights as set forth in “The Offer—Withdrawal Rights,” retain all Shares until the expiration date of the Offer as so extended; or (iii) waive the unsatisfied conditions and, subject to any requirement to extend the period of time during which the Offer must remain open, purchase all Shares validly tendered prior to the Expiration Date and not properly withdrawn or delay acceptance for payment or payment for Shares, subject to applicable law, until satisfaction or waiver of the conditions to the Offer. For a description of our right to extend, amend, delay or terminate the Offer, see “The Offer—Extension of Tender Period; Termination; Amendment” and “The Offer—Conditions to the Offer.”

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 Offer to Purchase, Omnicare beneficially owns 100 shares of common stock of the Company. According to the Company’s Quarterly Report on Form 10-Q filed May 14, 2004, as of May 11, 2004, there were 43,672,753 Shares outstanding (exclusive of the 100 Shares owned by Omnicare) and 259,980 Shares were to be issued in connection with the Company’s joint plan of reorganization confirmed by the Bankruptcy Court on September 20, 2001. During the Company’s second quarter 2004 earnings conference call on May 13, 2004, the Company disclosed that there were 2,281,904 Shares reserved for issuance upon the exercise of outstanding options to purchase Shares. 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. Extension of Tender Period; Termination; Amendment.

We reserve the right to extend the Expiration Date, in our sole discretion, if at the scheduled Expiration Date any of the conditions to the Offer have not been satisfied or waived. We also have the right to extend the Offer for any period required by any rule, regulation, interpretation or position of the Securities and Exchange

8

Commission (the “SEC”) or the SEC Staff applicable to the Offer or any period required by applicable law. We expressly reserve the right to waive (to the extent legally permissible) any of the conditions to the Offer, to make any change in the terms of our conditions to the Offer and to provide a subsequent offering period for the Offer in accordance with the Exchange Act Rule 14d-11.

If we increase or decrease the percentage of Shares being sought or increase or decrease the consideration to be paid for Shares pursuant to the Offer and the Offer is scheduled to expire at any time before the expiration of 10 business days from, and including, the date that notice of such increase or decrease is first published, sent or given in the manner specified below, the Offer will be extended until the expiration of 10 business days from, and including, the date of such notice. If we make a material change in the terms of the Offer (other than a change in the price to be paid in the Offer or the percentage of securities sought) or in the information concerning the Offer, or waive a material condition of the Offer, we will extend the Offer, if required by applicable law, for a period sufficient to allow you to consider the amended terms of the Offer. In a published release, the SEC has stated its view that an offer must remain open for a minimum period of time following a material change in the terms of such offer and that the waiver of a condition such as the Minimum Condition is a material change in the terms of an offer. The release states that an offer should remain open for a minimum of five business days from the date that the material change is first published, sent or given to shareholders, and that if material changes are made with respect to information that approaches the significance of the price to be paid in the offer or the percentage of shares sought in the offer, a minimum of 10 business days may be required to allow adequate dissemination and investor response. “Business day” means any day other than Saturday, Sunday or a federal holiday and consists of the time period from 12:01 a.m. through 12:00 Midnight, New York City time.

Any extension, delay, termination, waiver or amendment will be followed as promptly as practicable by a public announcement, in the case of an extension of the Offer to be made no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date, in accordance with the public announcement requirements of the Exchange Act Rule 14e-1(d). Subject to applicable law (including the Exchange Act Rules 14d-4(d) and 14d-6(c), which require that material changes in the information published, sent or given to any shareholders in connection with the Offer be promptly disseminated to shareholders in a manner reasonably designed to inform them of such changes), and without limiting the manner in which we may choose to make any public announcement, we have no obligation to publish, advertise or otherwise communicate any public announcements other than by issuing a press release through Business Wire.

If we extend the time during which the Offer is open, or if we are delayed in our acceptance for payment of or payment for Shares pursuant to the Offer for any reason, then, without prejudice to our rights under the Offer, the Depositary may retain tendered Shares on our behalf and those Shares may not be withdrawn except to the extent tendering shareholders are entitled to withdrawal rights as described herein under “The Offer—Withdrawal Rights.” However, our ability to delay the payment for Shares that we have accepted for payment is limited by the Exchange Act Rule 14e-1(c), which requires that a bidder pay the consideration offered or return the securities deposited by or on behalf of shareholders promptly after the termination or withdrawal of the bidder’s offer.

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

3. Acceptance for Payment and Payment.

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 pay for all Shares

9

that are validly tendered on or prior to the Expiration Date and not properly withdrawn pursuant to the Offer as soon as we are permitted to do so under applicable law, subject to the satisfaction or waiver of the conditions set forth in “The Offer—Conditions to the Offer.” 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 herein under “The Offer—Certain Legal Matters; Regulatory Approvals.” 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 “The Offer—Extension of Tender Period; Termination; Amendment.”

For purposes of the Offer, we shall be deemed to have accepted for payment tendered Shares when, as and if we give oral or written notice of our acceptance to the Depositary. We will pay for Shares accepted for payment pursuant to the Offer by depositing the purchase price with the Depositary. The Depositary will act as your agent for the purpose of receiving payments from us and transmitting such payments to you. In all cases, payment for Shares accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of certificates for such Shares (or of a confirmation of a book-entry transfer of such Shares into the Depositary’s account at the Book-Entry Transfer Facility (as defined in “The Offer—Procedure for Tendering Shares”)) and a properly completed and duly executed Letter of Transmittal and any other required documents. Accordingly, payment may be made to tendering shareholders at different times if delivery of the Shares and other required documents occurs at different times. For a description of the procedure for tendering Shares pursuant to the Offer, see “The Offer—Procedure for Tendering Shares.”

Under no circumstances will we pay interest on the consideration paid for Shares pursuant to the Offer, regardless of any delay in making such payment. If we increase the consideration to be paid for Shares pursuant to the Offer, we will pay such increased consideration for all Shares purchased pursuant to 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. If any tendered Shares are not purchased pursuant to the Offer for any reason, or if certificates are submitted for more Shares than are tendered, certificates for such unpurchased or untendered Shares will be returned (or, in the case of Shares tendered by book-entry transfer, such Shares will be credited to an account maintained at the Book-Entry Transfer Facility, as defined below), without expense to you, as promptly as practicable following the expiration or termination of the Offer.

4 . Procedure for Tendering Shares.

Valid Tender of Shares. To tender Shares pursuant to the Offer, either (i) the Depositary must receive at one of its addresses set forth on the back cover of this Offer to Purchase (A) a properly completed and duly executed Letter of Transmittal and any other documents required by the Letter of Transmittal and (B) the Share certificate(s) evidencing the Shares (the “Share Certificates”) to be tendered or delivery of such Shares pursuant to the procedures for book-entry transfer described below (and a confirmation of such delivery, including an Agent’s Message (as defined below) if the tendering shareholder has not delivered a Letter of Transmittal), in each case by the Expiration Date, or (ii) you must comply with the guaranteed delivery procedure described below.

The method of delivery of Share Certificates and all other required documents, including delivery through the Book-Entry Transfer Facility (as defined below), is at the option and risk of the tendering shareholder, and the delivery will be deemed made only when actually received by the Depositary, including, in the case of a book-entry transfer, by Agent’s Message (as defined below). If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery.

10

Book-Entry Delivery. The Depositary will establish an account with respect to the Shares at The Depository Trust Company (the “Book-Entry Transfer Facility”) for purposes of the Offer within two business days after the date of this Offer to Purchase, and any financial institution that is a participant in the system of the Book-Entry Transfer Facility may make delivery of Shares by causing the Book-Entry Transfer Facility to transfer such Shares into the Depositary’s account in accordance with the procedures of the Book-Entry Transfer Facility. However, although delivery of Shares may be effected through book-entry transfer, the Letter of Transmittal properly completed and duly executed together with any required signature guarantees or an Agent’s Message (as defined below) and any other required documents must, in any case, be received by the Depositary at one of its addresses set forth on the back cover of this Offer to Purchase by the Expiration Date, or you must comply with the guaranteed delivery procedure described below. “Agent’s Message” means a message, transmitted by the Book-Entry Transfer Facility to, and received by, the Depositary and forming a part of a book-entry confirmation which provides that the Book-Entry Transfer Facility has received an express acknowledgment from the participant in the Book-Entry Transfer Facility tendering the Shares that are the subject of such book-entry confirmation which such participant has received, and agrees to be bound by, the terms of the Letter of Transmittal and that Purchaser may enforce such agreement against such participant.

DELIVERY OF THE LETTER OF TRANSMITTAL AND ANY OTHER REQUIRED DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.

Signature Guarantees. Except as otherwise provided below, all signatures on a 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. (each an “Eligible Institution”). Signatures on a Letter of Transmittal need not be guaranteed (i) if the Letter of Transmittal is signed by the registered holder of the Shares tendered therewith and such holder has not completed the box entitled “Special Payment Instructions” on the Letter of Transmittal or (ii) if such Shares are tendered for the account of an Eligible Institution. See Instructions 1, 5, 6 and 7 of the Letter of Transmittal.

Guaranteed Delivery. If you wish to tender Shares pursuant to the Offer and cannot deliver such Share Certificates and all other required documents to the Depositary by the Expiration Date, or cannot complete the procedure for delivery by book-entry transfer on a timely basis, you may nevertheless tender such Shares if all of the following conditions are met:

(i) such tender is made by or through an Eligible Institution;

(ii) a properly completed and duly executed Notice of Guaranteed Delivery in the form provided by Purchaser is received by the Depositary (as provided below) by the Expiration Date; and

(iii) the Share Certificates (or a confirmation of a book-entry transfer into the Depositary’s account at the Book-Entry Transfer Facility), together with a properly completed and duly executed Letter of Transmittal (or facsimile thereof) with any required signature guarantee or an Agent’s Message and any other documents required by the Letter of Transmittal, are received by the Depositary within three business days after the date of execution of the Notice of Guaranteed Delivery.

The Notice of Guaranteed Delivery may be delivered by hand or transmitted by facsimile transmission or mailed to the Depositary and must include a guarantee by an Eligible Institution in the form set forth in such Notice. The method of delivery of Shares and all other required documents, including through the Book-Entry Transfer Facility, is at your option and risk, and the delivery will be deemed made only when actually received by the Depositary. If Share Certificates are sent by mail, we recommend registered mail with return receipt requested, properly insured.

Backup Withholding. Under current U.S. federal income tax law, the Depositary may be required to withhold and pay over to the Internal Revenue Service (“IRS”) a portion of any payments made to certain

11

shareholders or other payees pursuant to the Offer or the Proposed Merger. 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 not subject to such backup withholding by completing the Substitute Form W-9 included in the Letter of Transmittal. Certain persons (including, among others, corporations and certain non-U.S. individuals and entities) are not subject to backup withholding. If a tendering shareholder or other payee does not provide its correct TIN or fails to provide the certifications described above, the IRS may impose a penalty on such person, and reportable payments to such person may be subject to backup withholding. All shareholders tendering Shares pursuant to the Offer should complete and sign the Substitute Form W-9 included in the Letter of Transmittal to provide the information necessary to avoid backup withholding. If you are a non-resident alien or a non-U.S. entity not subject to backup withholding, you must give the Depositary a properly completed Form W-8BEN in order to avoid backup withholding with respect to payments made to you.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be refunded or credited against a person’s U.S. federal income tax liability, provided that the required information is furnished to the IRS.

Grant of Proxy. By executing a Letter of Transmittal (or delivering an Agent’s Message), you irrevocably appoint designees of Purchaser as your proxies in the manner set forth in the Letter of Transmittal to the full extent of your rights with respect to the Shares tendered and accepted for payment by us (and any and all other Shares or other securities issued or issuable in respect of such Shares on or after the date of this Offer to Purchase). All such proxies are irrevocable and coupled with an interest in the tendered Shares. Such appointment is effective only upon our acceptance for payment of such Shares. Upon such acceptance for payment, all prior proxies and consents granted by you with respect to such Shares and other securities will, without further action, be revoked, and no subsequent proxies may be given nor subsequent written consents executed (and, if previously given or executed, will cease to be effective). Our designees will be empowered to exercise all your voting and other rights as they, in their sole discretion, may deem proper at any annual, special or adjourned meeting of the Company’s shareholders, by written consent or otherwise. We reserve the right to require that, in order for Shares to be validly tendered, immediately upon our acceptance for payment of such Shares, we are able to exercise full voting rights with respect to such Shares and other securities (including voting at any meeting of shareholders then scheduled or acting by written consent without a meeting).

The foregoing proxies are effective only upon acceptance for payment of Shares pursuant to the Offer. The Offer does not constitute a solicitation of proxies, absent a purchase of Shares, for any meeting of the Company’s shareholders, which will be made only pursuant to separate proxy solicitation materials complying with the Exchange Act.

The tender of Shares pursuant to any one of the procedures described above will constitute your acceptance of the Offer, as well as your representation and warranty that (i) you own the Shares being tendered and (ii) you have the full power and authority to tender, sell, assign and transfer the Shares tendered, as specified in the Letter of Transmittal. Our acceptance for payment of Shares tendered by you pursuant to the Offer will constitute a binding agreement between us with respect to such Shares, upon the terms and subject to the conditions of the Offer.

Validity. We will determine, in our sole discretion, all questions as to the form of documents and the validity, eligibility (including time of receipt) and acceptance for payment of any tender of Shares, and our determination shall be final and binding. We reserve the absolute right to reject any or all tenders of Shares that we determine not to be in proper form or the acceptance for payment of or payment for which may, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any defect or irregularity in any tender of Shares. Our interpretation of the terms and conditions of the Offer will be final and binding. None of Omnicare, Purchaser, the Dealer Managers, the Depositary, the Information Agent or any other person will be under any duty to give notification of any defect or irregularity in tenders or waiver of any such defect or irregularity or incur any liability for failure to give any such notification.

12

5. Withdrawal Rights.

You may withdraw tenders of Shares made pursuant to the Offer at any time prior to the Expiration Date. Thereafter, such tenders are irrevocable, except that they may be withdrawn after August 2, 2004 unless such Shares are accepted for payment as provided in this Offer to Purchase. If we extend the period of time during which the Offer is open, are delayed in accepting for payment or paying for Shares pursuant to the Offer for any reason or are unable to accept Shares for payment pursuant to the Offer for any reason, then, without prejudice to our rights under the Offer, the Depositary may, on our behalf, retain all Shares tendered, and such Shares may not be withdrawn except as otherwise provided in this section.

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

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

If Purchaser provides a subsequent offering period following the Offer, no withdrawal rights will apply to Shares tendered during that subsequent offering period or to Shares tendered in the Offer and accepted for payment.

6. Certain U.S. Federal Income Tax Consequences.

The following is a summary of certain 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 Offer to Purchase and all of which may change, possibly with retroactive effect. The summary is for general information only and 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

13

purposes, is a non-resident 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 this Offer to Purchase and that all conditions to closing the Offer and the Proposed Merger as set forth in this Offer to Purchase are satisfied without waiver.

THIS SUMMARY IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. 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 APPLICATION AND EFFECT OF STATE, LOCAL AND FOREIGN TAX LAWS.

The sale of Shares pursuant to the Offer or exchange of Shares in the Proposed Merger will be a taxable transaction for U.S. federal income tax purposes. In general, a shareholder who sells Shares pursuant to the Offer or receives Merger Consideration in exchange for Shares pursuant to the Proposed Merger will recognize gain or loss for U.S. federal income tax purposes equal to the difference, if any, between the amount of cash received (not taking into account any tax withholding) and the holder’s adjusted tax basis in the Shares sold pursuant to the Offer or exchanged pursuant to the Proposed Merger. Gain or loss will be determined separately for each block of Shares (i.e., Shares acquired for the same cost in a single transaction) sold pursuant to the Offer or exchanged pursuant to the Proposed Merger. Any such gain or loss generally will be long-term capital gain or loss if the shareholder has held the Shares for more than one year. Long-term capital gain of noncorporate shareholders generally is subject to federal income tax at a maximum rate of 15%. Certain limitations apply to the deduction of capital losses.

Proceeds from the sale of Shares pursuant to the Offer or the exchange of Shares in the Proposed Merger generally are subject to information reporting, and may be subject to backup withholding at the applicable rate (currently 28%) if the shareholder or other payee fails to provide a valid taxpayer identification number and comply with certain certification procedures or otherwise establish an exemption from backup withholding. See “The Offer — Procedure for Tendering Shares — Backup Withholding.”

As described in “The Offer—Certain Information Concerning the Company,” the Company distributed the common stock of Genesis HealthCare Corporation (“GHC”) to its shareholders in a spin-off completed in December 2003. We believe that the Offer and Proposed Merger should not negatively affect the U.S. federal income tax consequences of that spin-off. Shareholders who received stock of GHC in the spin-off should consult their own tax advisors regarding the U.S. federal and other tax consequences to them of the spin-off, the Offer and the Proposed Merger.

8. Certain Information Concerning the Company.

General. The following information is based solely on publicly available documents filed by the Company with the SEC. The Company was incorporated in May 1985 as a Pennsylvania corporation and was formerly named Genesis Health Ventures, Inc. The Company has its principal executive offices at 601 East Pratt Street, 3rd Floor, Baltimore, Maryland 21202. The telephone number of the Company’s executive offices is (410) 528-7300.

Prior to December 1, 2003, the Company’s operations were comprised of two primary business segments: pharmacy services and inpatient services. On December 1, 2003, the Company completed a distribution (“spin-off”) of the common stock of GHC, which held the inpatient services business, and on December 2, 2003, changed its name to NeighborCare, Inc. and changed its trading symbol to “NCRX.” The spin-off was effected by way of a pro rata distribution of the common stock of GHC to holders of the Company’s common stock on December 1, 2003 at a rate of 0.5 of a share of GHC stock for each share of the Company’s stock owned as of October 15, 2003. As a result of the spin-off, the Company continues to own and operate its pharmacy services business and its group purchasing business and GHC owns and operates what was formerly the Company’s inpatient services business (as well as the Company’s former rehabilitation therapy, diagnostic, respiratory and management services businesses).

15

The Company’s institutional pharmacy business provides prescription and non-prescription pharmaceuticals, infusion therapy and medical supplies and equipment to the elderly, chronically ill and disabled in long-term care facilities, including skilled nursing facilities, assisted living facilities, residential and independent living communities and other institutional healthcare facilities. The pharmacy services provided in these settings are tailored to meet the needs of the institutional customer. These services include highly specialized packaging and dispensing systems, computerized medical records processing and 24-hour emergency services. The Company also provides pharmacy consulting services to assure proper and effective drug therapy, including monitoring and reporting on prescription drug therapy and assisting the facility in compliance with applicable federal and state regulations. The Company currently serves more than 2,500 facility customers.

The Company’s community-based professional pharmacies are retail operations branded under the NeighborCare^® name that are located in or near medical centers, hospitals and physician office complexes which provide prescription and non-prescription medications and certain medical supplies, as well as personal service and consultation by licensed pharmacists.

The Company’s home infusion, respiratory and medical equipment distribution centers provide a wide array of products and services to support the home care needs of a range of individuals of all ages. The Company works with physicians, hospital discharge planners, case managers and managed care organizations who refer these individuals to the Company. The products and services provided by the Company include respiratory and medical equipment (such as oxygen, hospital beds, wheelchairs and respiratory medications), as well as home infusion (such as antibiotics, total parenteral nutrition, or “TPN,” chemotherapy and pain management).

The Company also owns and operates Tidewater Healthcare Shared Services Group, Inc., or “Tidewater,” one of the largest long-term care group purchasing companies in the United States. Tidewater provides purchasing and shared service programs specially designed to meet the needs of eldercare centers and other long-term care facilities.

Preferred Stock Purchase Rights. The following description of the Rights is based solely upon publicly available documents filed by the Company with the SEC. This description does not purport to be complete and is qualified in its entirety by reference to the Rights Agreement by and between Genesis Health Ventures, Inc. and Stocktrans, Inc., dated as of November 18, 2003, which is filed as Exhibit 4.1 to the Company’s Report on Form 8-A filed with the SEC on November 18, 2003.

The Company entered into a Rights Agreement on November 18, 2003, pursuant to which it declared a dividend distribution of one preferred stock purchase right for each outstanding share of common stock, payable on December 1, 2003. The Rights become exercisable upon the earlier to occur of: (i) 10 days after the date a person (other than the Company, any subsidiary of the Company, any employee benefit plan of the Company or of any subsidiary of the Company or any entity holding Shares of the Company for or pursuant to the terms of any such plan) (an “Acquiring Person”) announces that it has acquired or obtained the right to acquire beneficial ownership of 20% or more of the outstanding common stock of the Company or (ii) 10 business days (or on such date as may be determined by the board of directors of the Company prior to such time as any person becomes an Acquiring Person) after the date of the commencement by any person (other than the Company, any subsidiary of the Company, any employee benefit plan of the Company or of any subsidiary of the Company or any entity holding Shares of the Company for or pursuant to the terms of any such plan) of a tender or exchange offer the consummation of which would result in any person acquiring beneficial ownership of 20% or more of the outstanding common stock (the “Distribution Date”).

Each Right initially entitles the registered holder of common stock to purchase one one-hundredth of a share of Series B Preferred Stock at a price of $100 per one one-hundredth of a share, subject to certain anti-dilution

16

adjustments. The Rights have “flip-in” and “flip-over” provisions that are triggered when a person becomes an Acquiring Person (the “Stock Acquisition Date”). Upon the Stock Acquisition Date, each Right entitles its holder to purchase an amount of common stock having a then current market value equal to two times the exercise price of the Right. Rights owned by any person who becomes an Acquiring Person will become null and void.

The Rights Agreement provides that, until the Distribution Date, the Rights will be transferred with and only with the common stock. As soon as practicable following the Distribution Date, rights certificates will be mailed to holders of record of common stock as of the close of business on the Distribution Date and such separate rights certificates alone will evidence the Rights.

In the event that the Company is acquired in a merger or other business combination or 50% or more of its assets or earning power are sold after a person has become an Acquiring Person, then each Right entitles its holder to receive an amount of the stock of the acquiror having a market value equal to twice the then current exercise price of the Right.

At any time after any person becomes an Acquiring Person, and prior to the acquisition by such person of 50% of the outstanding common stock, a majority of the board of directors of the Company may exchange the Rights, in whole or in part, for shares of common stock at an exchange ratio of one share of common stock per Right. At any time prior to the existence of an Acquiring Person, the Company may redeem the Rights in whole, but not in part, for $0.01 per Right. The rights will expire on December 1, 2013, unless extended or earlier redeemed or exchanged.

Based on publicly available information, the Purchaser believes that, as of the date of this Offer to Purchase, the Rights are not exercisable, the rights certificates have not been issued and the Rights are evidenced by the Share Certificates. The Purchaser believes that, as a result of the commencement of the Offer, the Distribution Date may occur as early as 10 business days from the first public announcement of the Purchaser’s intention to make the Offer, unless the Company’s board of directors determines to postpone the Distribution Date. The Purchaser believes that if the Rights Condition is satisfied, the Rights Agreement will not be an impediment to consummating either the Offer or the Proposed Merger.

The existence of the Rights has the practical effect of precluding Omnicare and the Purchaser from consummating the Offer, regardless of the extent to which the Company’s shareholders wish to sell their Shares pursuant to the Offer.

Omnicare is subject to the informational requirements of the Exchange Act and in accordance therewith files periodic reports, proxy statements and other information with the SEC relating to its business, financial condition and other matters. Omnicare is required to disclose in such proxy statements certain information, as of particular dates, concerning its directors and officers, their remuneration, stock options granted to them, the principal holders of its securities and any material interests of such persons in transactions with Omnicare. Such reports, proxy statements and other information should be available for inspection and copying at the offices of the SEC in the same manner as set forth with respect to the Company in “Certain Information Concerning the Company—Available Information.”

10. Source and Amount of Funds.

The Offer is conditioned upon receipt by Omnicare of the proceeds of the financings contemplated by its existing Commitment Letter (as defined below) 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. We will need approximately $1.4 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 Company’s 6.875% senior subordinated notes due 2013 ($250 million aggregate principal amount as of March 31, 2004).

Purchaser expects to obtain the funds required to consummate the Offer through capital contributions or advances made by Omnicare. Omnicare has obtained a commitment letter (the “Commitment Letter”) from JPMorgan Chase Bank, Lehman Commercial Paper Inc., an affiliate of Lehman Brothers Inc., the Dealer Manager, SunTrust Bank, Canadian Imperial Bank of Commerce and Merrill Lynch Bank USA (collectively, the “Commitment Parties”), pursuant to which, subject to specified conditions, the Commitment Parties have agreed to provide to Omnicare $2.4 billion (the “Credit Facilities”) to finance the Offer and the Proposed Merger. A portion of the Credit Facilities may be provided by a syndicate of banks and other financial institutions arranged by J.P. Morgan Securities Inc., Lehman Brothers Inc. and SunTrust Capital Markets, Inc. (collectively, the “Joint Lead Arrangers”). SunTrust Bank will act as administrative agent for the Credit Facilities, J.P. Morgan Securities Inc. and Lehman Brothers Inc. will act as co-syndication agents for the Credit Facilities and CIBC World

20

Markets Corp. and Merrill Lynch, Pierce, Fenner & Smith Incorporated will act as co-documentation agents for the Credit Facilities.

The Credit Facilities consist of (i) a $600 million revolving credit facility, with one sub-facility for letters of credit and one sub-facility for swing line loans, each in the amount of up to $50 million (“Revolving Credit Facility”) maturing five years after the initial funding date (the “Closing Date”), (ii) a $700 million senior term loan facility (the “Senior Term Loan Facility”) maturing five years after the Closing Date and (iii) a $1.1 billion 364-day facility (the “364-Day Facility”) maturing 364 days after the Closing Date. 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 the Company and to pay related fees and expenses and, after the Closing Date, the proceeds of the Revolving Credit Facility may be used for general corporate purposes of Omnicare and its subsidiaries in the ordinary course of business.

Borrowings under the Credit Facilities will bear interest, at Omnicare’s option, at a rate equal to (i) the Eurodollar Rate (adjusted for reserves) plus an applicable margin (based on Omnicare’s senior unsecured long-term debt securities rating (“Omnicare’s Rating”) and ranging from 0.75% to 2.50%) or (ii) a Base Rate at the higher of the prime rate or the federal funds effective rate from time to time plus 0.5%. Borrowings bearing interest based upon the Eurodollar Rate will be for interest periods of 1, 2, 3, 6 or, if available from all lenders, nine or twelve months. All interest will be paid at the end of the applicable interest period or quarterly, whichever is earlier. In addition, a commitment fee will be payable at a specified per annum rate (based on Omnicare’s Rating and ranging from 0.175% to 0.50%) on the unused portion of the Revolving Credit Facility.

Borrowings under the Senior Term Loan Facility shall be repayable quarterly in the specified amount as follows: Year 1–10%, Years 2 and 3–15%, Year 4–20% and Year 5–40%. Omnicare may prepay and reduce commitments under the Credit Facilities at any time without premium or penalty. The 364-Day Credit Facility is subject to mandatory prepayments with the proceeds of any sale or issuance of Omnicare’s equity or incurrence of certain indebtedness by Omnicare or its subsidiaries.

Borrowings under the Credit Facilities will be guaranteed by Omnicare’s direct and indirect domestic subsidiaries which, together with Omnicare’s assets and revenues, account for at least 90% of Omnicare’s and its subsidiaries’ consolidated assets and revenues.

The Commitment Parties’ commitments to provide the Credit Facilities are subject to, among other things, (i) non occurrence since December 31, 2003 of any material adverse change in the business, operations, property or financial condition of Omnicare and its subsidiaries, taken as a whole, or the Company and its subsidiaries, taken as a whole, (ii) non-discovery by the Commitment Parties of additional information that is inconsistent in a material and adverse manner with any previously disclosed information, (iii) non occurrence of any material adverse change in financial, banking or capital market conditions that would materially impair the syndication of the Credit Facilities and (iv) the execution and delivery of satisfactory loan documentation. The conditions precedent to the borrowings under the Credit Facilities include, among other things, (i) if the Offer, but not Proposed Merger, is consummated on the Closing Date (A) the terms of the Offer shall be conditioned on that the certain specified conditions shall not apply to or otherwise restrict the Offer and the Proposed Merger and (B) Purchaser shall have acquired a sufficient number of Shares to satisfy the Minimum Condition, (ii) if the Offer and the Proposed Merger are consummated on the Closing Date, the acquisition of the Shares shall have been consummated for a specified price, (iii) receipt of all necessary consents and approvals (including regulatory approvals) to consummate the Offer or the Proposed Merger and (iv) delivery of customary closing documents and instruments.

The definitive documentation relating to the Credit Facilities also will contain representations, warranties, covenants, events of default and conditions 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.

21

SunTrust Bank, as administrative agent, CIBC Inc., and the other parties signatory thereto. The financial covenants will include a minimum fixed charge coverage ratio and a minimum consolidated net worth.

Omnicare will be required to pay certain fees to the Commitment Parties and syndication fees to the lenders in connection with the Credit Facilities. Omnicare and Purchaser will be required to pay certain expenses of, and provide customary indemnities to, the Joint Lead Arrangers, Commitment Parties and the other lenders under the Credit Facilities.

The foregoing summary of the terms and conditions of the Commitment Letter and the Credit Facilities is qualified in its entirety by reference to the text of the Commitment Letter, a copy of which is filed as an exhibit to the Tender Offer Statement on Schedule TO of the Omnicare and Purchaser filed with the Commission in connection with the Offer (the “Schedule TO”) and is incorporated herein by reference and may be inspected in the same manner as set forth in “The Offer—Certain information Concerning Purchaser and Omnicare—Available Information.”

When definitive agreements relating to the Credit Facilities are executed, copies will be filed as exhibits to amendments to the Schedule TO. Omnicare anticipates that the Credit Facilities will be repaid with internally generated funds, including those of the Company, and from the proceeds of future borrowings or other debt or equity financings. At this time, no specific plans or arrangements have been made for any such future borrowings or other financings. However, after consummation of the Proposed Merger, Omnicare intends to explore various possible plans for long-term debt or other financing that might be considered to refinance all or part of the Credit Facilities.

11. Background of the Offer.

As part of the continuous evaluation of its business, Omnicare regularly considers a variety of strategic options and potential transactions. As part of this process, Omnicare has evaluated various alternatives for expanding its business and has completed numerous acquisitions in the institutional pharmacy industry since 1988.

In late February 2004, Mr. Joel F. Gemunder, President and Chief Executive Officer of Omnicare, called Mr. John J. Arlotta, Chairman, President and Chief Executive Officer of the Company, to invite Mr. Arlotta to dinner to discuss, generally, the institutional pharmacy business and, more specifically, a transaction involving Omnicare.

On March 2, 2004, Messrs. Gemunder and Arlotta had dinner. During dinner, Messrs. Gemunder and Arlotta discussed, among other things, the possibility of a business combination involving the Company and Omnicare. Mr. Arlotta advised Mr. Gemunder that he would discuss the potential business combination with the Company’s board of directors.

On March 29, 2004, Messrs Gemunder and Arlotta had a telephone conversation as a follow-up to their March 2, 2004 meeting. During the call, Messrs. Gemunder and Arlotta again discussed the possibility of a business combination between the Company and Omnicare. Mr. Arlotta again stated that he would discuss the possibility of a business combination with the Company’s board of directors.

22

As a follow-up to the March 29, 2004 conversation, on March 30, 2004, Mr. Gemunder sent the following letter to Mr. Arlotta:

[LETTERHEAD OF OMNICARE, INC.]

BY FACSIMILE AND FIRST-CLASS MAIL

Mr. John Arlotta

Chairman and Chief Executive Officer

NeighborCare, Inc.

7 East Lee Street

Baltimore, Maryland 21202

Dear John:

It was a pleasure speaking with you again yesterday. I was very pleased to hear you will be discussing our proposal with NeighborCare’s Board at its next meeting in mid-April. In light of that board meeting, I thought it would be helpful to provide you with some specifics about our proposal to combine NeighborCare and Omnicare.

Based upon our knowledge of NeighborCare from publicly available information, Omnicare is prepared to acquire NeighborCare for $30.00 per share, which would be payable in a combination of cash and Omnicare common stock. This price represents a 23.6% premium to NeighborCare’s closing share price of $24.27 today. If, however, you or the NeighborCare Board has a different view on the form of consideration to be paid in the proposed transaction, we are open to discussing this matter, as well as any other matter relating to a proposed combination of the two companies, with you.

As we discussed at dinner a few weeks ago, our proposal to combine NeighborCare and Omnicare presents an excellent opportunity for NeighborCare shareholders to realize a substantial return on their investment and to participate in the upside of an ownership stake in what would be the premier institutional pharmacy company. Given these significant benefits, we believe that NeighborCare and Omnicare shareholders would applaud such a transaction. Also, our Board of Directors has authorized this proposal and fully supports a combination of NeighborCare and Omnicare.

As I mentioned to you during dinner, John, I have a great deal of respect for your professional accomplishments, and I know that there are a number of outstanding executives at NeighborCare. We believe that, taken together, the management talent resident in our two companies will be essential to the success of the combined company and will help lead us into the future.

I believe that our proposal to combine NeighborCare and Omnicare presents an excellent opportunity for both companies and their shareholders to realize substantial benefits. I hope that you and the NeighborCare Board share this vision.

I want to emphasize to you and the NeighborCare Board our seriousness about this proposal and our commitment to a combination of NeighborCare and Omnicare. We are prepared to meet with you at your earliest convenience to see if we can negotiate the terms of a mutually acceptable transaction. We will commit the resources necessary, together with our outside advisors, to proceed expeditiously and are convinced that we could reach agreement on the material terms of a transaction quickly. We also have, together with our outside counsel, analyzed the required regulatory approvals and are confident that all necessary approvals can be obtained in a timely fashion.

We are sending this letter, and would be meeting with you, on the basis that this letter and its contents, as well as all of our discussions, remain confidential. Obviously our proposal is subject to the completion of customary due diligence and the negotiation and the execution of a mutually satisfactory definitive agreement.

If you have any questions or would like me to clarify any aspect of our proposal, please do not hesitate to call me at (859) 392-3305. I look forward to hearing from you soon.

Sincerely,

Dear Joel:

This will respond to your letter of March 30, which the Board of Directors of NeighborCare has reviewed carefully.

The Board is unanimous in concluding that your proposal is opportunistic and not in the best interests of NeighborCare. Accordingly, we have no interest in pursuing a transaction, nor in any further discussion of the matter. The Board has great confidence in NeighborCare’s new leadership team and strong, post-spin-off business plan, which is in its initial stages.

We have no doubt that aggressively executing on the business plan is the best course for our company, its shareholders and other constituencies. Pursuing your proposal would be counterproductive for your company, as well as for ours.

Sincerely,

BY FACSIMILE AND FEDEX

Mr. John J. Arlotta

Chairman, President and Chief Executive Officer

NeighborCare, Inc.

601 East Pratt Street, 3rd Floor

Baltimore, Maryland 21202

Dear John:

As we discussed in early March, and as set forth in my letter to you dated March 30, 2004, we believe that a combination of Omnicare and NeighborCare is compelling and will provide substantial benefits to both companies’ shareholders and other interested constituencies. We are, however, disappointed by your rejection of our offer to acquire NeighborCare and your Board’s unwillingness to engage in any further discussion of the matter.

For this reason, Omnicare is making public its offer to acquire all of the outstanding shares of NeighborCare common stock for $30.00 per share in cash. This offer represents a 70% premium to NeighborCare’s closing share price of $17.67 on May 21, 2004. As we have discussed before, if you or the NeighborCare Board have a different view on the form of consideration or other aspects of our offer, we are willing to discuss this, as well as any other matter relating to a proposed combination of Omnicare and NeighborCare, with you.

We continue to believe that a combination of Omnicare and NeighborCare makes compelling business sense for all of NeighborCare’s shareholders and other constituencies. It also provides a unique opportunity for your shareholders to realize maximum value immediately for their shares. The combination of Omnicare and NeighborCare would result in the creation of a premier institutional pharmacy company and position the combined company to provide valuable benefits to all of its constituencies. I would welcome the opportunity to discuss further with you the substantial benefits of our offer.

Considering these substantial benefits, we are confident that, given the opportunity, NeighborCare’s shareholders and other constituents will enthusiastically support our offer.

Omnicare’s Board fully supports this offer and no further corporate action on our part is required to consummate this transaction. We have obtained commitments for financing that are sufficient to consummate the transaction.

It is our strong preference to work together with the NeighborCare Board to reach a mutually agreeable transaction. We and our advisors are available to meet with you and your advisors as soon as possible to discuss the terms of our offer and to negotiate a definitive agreement.

We are confident that you and your Board will recognize the substantial benefits of our offer and decide to discuss this matter with us. We believe that we can work together with you to quickly close a transaction.

Sincerely,

/S/  JOEL F. GEMUNDER

Mr. Joel F. Gemunder

Omnicare, Inc.

100 East RiverCenter Blvd.

Suite 1600

Covington, KY 41011

Dear Joel:

This will respond to your letter of May 24, 2004 in which you repeated your unsolicited $30 per share acquisition proposal from March 30. As we stated in our letter of April 20, the NeighborCare Board is unanimously of the view that your proposal is blatantly opportunistic and not in the best interests of NeighborCare, its shareholders and its other constituencies. We had no interest then, and we have no interest now, in pursuing a transaction, nor in any further discussion of the matter.

As you know, we are just emerging from a major strategic restructuring that resulted in the separation of our nursing home business, a new leadership team and a new, fully independent approach to the institutional pharmacy market. We are in the early stages of a new business plan that will leverage these very significant changes as well as important new initiatives that we have recently announced in automation. Our efforts are quickly reducing costs and achieving success with customers.

The Board has great confidence in the Company’s business plan and our new leadership, and we have no doubt that aggressively executing on that business plan is the best course for our company.

Accordingly, we see your proposal as nothing more than a cynical attempt to seize for Omnicare the long-term value and success of our great company, which rightly belongs to NeighborCare’s shareholders and other constituencies.

We intend to continue to compete in the marketplace and to provide superior service and value to our customers. We are confident that this course is best for our company, its shareholders and other constituencies. Both the Board and I have been unwavering on this point since you first raised the idea in late February. Pursuing your proposal would be counter-productive for your company, as well as for ours.

Sincerely,

/S/  JOHN J. ARLOTTA

Chairman, President and Chief Executive Officer

On June 3, 2004, Mr. Gemunder sent the following letter to the Company’s board of directors informing the board of Omnicare’s intent to commence the Offer for $30.00 per Share in cash and made its contents public in a press release:

26

[LETTERHEAD OF OMNICARE, INC.]

June 3, 2004

Board of Directors

NeighborCare, Inc.

601 East Pratt Street, 3rd Floor

Baltimore, Maryland 21202

Dear NeighborCare Board Members:

We want to inform you that Omnicare, Inc. intends to commence a tender offer to purchase all of the outstanding shares of NeighborCare, Inc. common stock for $30.00 per share in cash. The combination of Omnicare and NeighborCare is too compelling to ignore, and our two companies are a strong strategic fit. We believe that the combination of Omnicare and NeighborCare will create a premier institutional pharmacy company.

We are disappointed that you have rejected our recent proposals to combine Omnicare and NeighborCare and are unwilling to even discuss a potential transaction. Given the obvious benefits of our offer to NeighborCare’s shareholders and other constituencies, we would like to emphasize some important points:

This is a premium offer for shareholders and other constituents.    As you must know, our offer for all of NeighborCare’s shares simply cannot be characterized as “opportunistic.” It is, on the contrary, an opportunity for your shareholders to realize a 70% premium to where NeighborCare was trading prior to our offer. Our offer represents an opportunity to create a stronger company with greater resources to provide quality care and expanded services for customers. The combined company will have a dynamic presence in the healthcare services sector and we recognize that fast growing companies like ours are continually looking for good management talent. Omnicare always has a place for good people. Your decision to reject our offer has prevented your shareholders and other constituents from taking advantage of these benefits.

The market reaction to NeighborCare’s second-quarter results and future business plan was clearly negative.    Widespread concern about NeighborCare’s performance and prospects after the announcement resulted in four of five analysts reducing their 2004 full-year NeighborCare EPS projections, and in a drop in analysts’ 12-month median price target on NeighborCare’s stock from $26 to $23. NeighborCare’s Board and shareholders may want to ask how long does one have to wait for premium value, when Mr. Arlotta recently stated in an interview that “We feel the greatest value is still three to five years down the road.”¹

Indeed, management’s long-term plan for stand-alone value creation appears to require extremely aggressive assumptions in order to generate shareholder value comparable to the $30 per share in cash that Omnicare is offering today.

Based on NeighborCare’s share price of $17.67 on May 21, the last trading day prior to Omnicare’s public offer, NeighborCare’s EPS would need to grow at approximately 45% per annum, or more than 100%, for the next two years, to deliver the equivalent of $30 per share today, on a present value basis and at current multiples.² There are no analyst projections today that approach this level of growth. Attempting to achieve this $30 value over time would subject shareholders to market risk and execution risk, since by management’s own admission, much of the company’s future growth is expected to come largely from cost improvement initiatives, some of which are not expected to be achieved until 2006.

¹ The Cincinnati Enquirer, 5/26/04

² Assuming an estimated NeighborCare cost of equity of 11%, $30.00 per share in cash today is equivalent to a share price of $36.96 in June 2006. Dividing this future share price of $36.96 by NeighborCare’s pre-Omnicare offer consensus P/E ratio of 18.7x, results in a 2006E EPS estimate of $1.97. A 2006E EPS estimate of $1.97 implies a compound annual EPS growth rate of approximately 45%, relative to NeigborCare’s 2004E consensus EPS of $0.94. (P/E ratio of 18.7x based on NeighborCare’s closing share price of $17.67 on May 21, 2004 and 2004E consensus EPS of $0.94; consensus based on Lehman Brothers 5/28/2004, Legg Mason 5/25/2004, Wachovia 5/24/2004, CIBC 5/18/2004, and Jefferies 5/14/2004).

27

Omnicare pays fair price for fair value.    We are mystified by the characterization of Omnicare’s approach as a “cynical attempt to seize” NeighborCare’s long term value and success, when the Board is well aware that Omnicare’s March 30 letter indicated that our $30 offer “would be payable in a combination of cash and Omnicare common stock.” We again indicated on May 25 that we are willing to sit down with the NeighborCare Board to discuss all aspects of our compelling offer.

Our all-cash $30 per share offer provides immediate certainty of value.    It represents not only a 70% premium to where NeighborCare was trading prior to our offer, but also a 40% premium over the 30-day trading average prior to the announcement of our offer, a 30% premium to Wall Street’s consensus target prices for NeighborCare’s stock over the next 12 months and is $4.00 more than NeighborCare’s previous all-time high. Despite the recent significant drop in NeighborCare’s share price, Omnicare 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.

The market’s favorable reaction to Omnicare’s offer is exceptional.    We are convinced that there is extensive third-party support in the financial community for this combination, and most importantly, your own shareholders are expressing their support for this transaction.³ Furthermore, in an extraordinary vote of confidence, Omnicare’s stock has risen over 9% since the announcement of our offer.⁴ Omnicare has successfully integrated more than 100 acquisitions over the past 15 years, and has delivered on the expected benefits to our shareholders.

We do not understand your statement that our call to negotiate is somehow counter-productive, and we are surprised at your unwillingness to even discuss our offer. We are confident that, given the opportunity, NeighborCare’s shareholders and other constituents will enthusiastically support our offer. If, as you say, you are committed to “the best course for your company,” we stand ready to discuss all aspects of our offer.

Sincerely,

/s/  JOEL F. GEMUNDER

12. Purpose and Structure of the Offer; Plans for the Company.

Purpose of the Offer. The purpose of this Offer is for Omnicare to acquire control of, and ultimately the entire equity interest in, the Company. The Offer, as the first step in the acquisition of the Company, is intended to facilitate the acquisition of the Company. The purpose of the Proposed Merger is to acquire all of the outstanding Shares not tendered and purchased pursuant to the Offer. If the Offer is successful, we intend to consummate the Proposed Merger as promptly as practicable.

If Purchaser owns 80% or more of the outstanding Shares, following consummation of the Offer, Purchaser intends to consummate the Proposed Merger as a “short-form” merger pursuant to Section 1924 of the PBCL. Under such circumstances, the approval of the Company’s board of directors or of any holder of Shares (other than Purchaser) would not be required. Upon consummation of the Proposed Merger, the Company will become a wholly owned subsidiary of Omnicare.

Plans for the Company. In connection with this Offer, Omnicare has reviewed and will continue to review various possible business strategies that it might consider in the event that Purchaser acquires control of the Company, whether pursuant to the Offer, the Proposed Merger or otherwise. Following a review of additional information regarding the Company, such strategies may involve, among other things, changes in the Company’s business, operations, corporate structure, capitalization and management.

13. Effect of the Offer on the Market for the Common Stock; Registration under the Exchange Act.

Reduced Liquidity; Possible Delisting. The tender of Shares pursuant to the offer will reduce the number of holders of the Shares and the number of Shares that might otherwise trade publicly and could adversely affect the liquidity and market value of the remaining Shares held by the public. The Shares are listed and principally traded on the NASDAQ. Depending on the number of Shares acquired pursuant to the offer, following consummation of the offer, the Shares may no longer meet the requirements of the NASDAQ for continued listing. For example, published guidelines of the NASDAQ indicate that the NASDAQ would consider delisting the outstanding Shares if, among other things: (i) the number of publicly held Shares (exclusive of holdings of officers, directors and beneficial owners of 10 percent or more) should fall below 750,000, (ii) the number of record holders of 100 or more Shares should fall below 400 or (iii) the aggregate market value of publicly held Shares should fall below $5 million.

If the NASDAQ were to delist the Shares, the market for the shares could be adversely affected. It is possible that the Shares would be traded on other securities exchanges or in the over-the-counter market and that price quotations would be reported by such exchanges, or by other sources. The extent of the public market for the Shares and the availability of such quotations would, however, depend upon the number of holders and/or the aggregate market value of the Shares remaining at such time, the interest in maintaining a market in the Shares on the part of securities firms, the possible termination of registration of the Shares under the Exchange Act, as described below, and other factors.

Status as “Margin Securities.” The Shares are presently “margin securities” under the regulations of the Federal Reserve Board, which has the effect, among other things, of allowing brokers to extend credit on the collateral of the Shares. Depending on the factors similar to those described above with respect to listing and market quotations, following consummation of the Offer, the Shares may no longer constitute “margin securities” for the purposes of the Federal Reserve Board’s margin regulations, in which event the Shares would be ineligible as collateral for margin loans made by brokers.

Registration under the Exchange Act. The Shares are currently registered under the Exchange Act. The Company can terminate that registration upon application to the SEC if the outstanding Shares are not listed on a national securities exchange and if there are fewer than 300 holders of record of the Shares. Termination of registration of the Shares under the Exchange Act would reduce the information that the Company must furnish

29

to its shareholders and to the SEC and would make certain provisions of the Exchange Act, such as the short-swing profit recovery provisions of Section 16(b) and the requirement of the furnishing a proxy statement in connection with shareholders meetings pursuant to Section 14(a) and the related requirement of furnishing an annual report to shareholders, no longer applicable with respect to the Shares. Furthermore, the ability of “affiliates” of the Company and persons holding “restricted securities” of the Company to dispose of such securities pursuant to Rule 144 under the Securities Act may be impaired or eliminated. If registration of the Shares under the Exchange Act were terminated, they would no longer be eligible for NASDAQ listing or for continued inclusion on the Federal Reserve Board’s list of “margin securities.”

14. Dividends and Distributions.

If on or after the date of this Offer to Purchase the Company should split, combine or otherwise change the Shares or its capitalization, acquire or otherwise cause a reduction in the number of outstanding Shares, or issue or sell any additional Shares (other than Shares issued pursuant to and in accordance with the terms in effect on the date of this Offer to Purchase of employee stock options outstanding prior to such date), shares of any other class or series of capital stock, other voting securities or any securities convertible into, or options, rights or warrants, conditional or otherwise, to acquire, any of the foregoing, then, without prejudice to our rights under “The Offer—Conditions to the Offer,” we may, in our sole discretion, make such adjustments in the purchase price and other terms of the Offer as we deem appropriate including the number or type of securities to be purchased.

15. Conditions to the Offer.

Notwithstanding any other provision of the Offer, we are not required to accept for payment or pay for any Shares, and we may terminate the Offer, if, prior to the Expiration Date, any of the Minimum Condition, the Rights Condition, the Subchapter 25F Condition, the Financing Condition or the Impairment Condition has not been satisfied, or all waiting periods under applicable antitrust laws, including the HSR Act, shall not have expired or been terminated. Furthermore, notwithstanding any other provision of the Offer, prior to the Expiration Date, we are not required to accept for payment or pay for any Shares, and we may terminate the Offer, if at any time on or after the date of this Offer to Purchase and prior to the Expiration Date, any of the following conditions exist:

(d) there shall have been any change, event or development having, or that could reasonably be expected to have, individually or in the aggregate, a material adverse effect on the condition (financial or otherwise), business, assets, liabilities or results of operations of the Company and its subsidiaries taken as a whole;

(e) any person (which includes a “person” as such term is defined in Section 13(d)(3) of the Exchange Act), other than Omnicare, Purchaser, any of their affiliates or any group of which any of them is a member, shall have acquired beneficial ownership of more than 5% of the outstanding Shares, or any group shall have been formed which beneficially owns more than 5% of the outstanding Shares, in each case other than any person or group that has disclosed such ownership prior to the date of the Offer, and no such person (other than Omnicare, Purchaser, any of their affiliates, or any group of which any of them is a member) or group shall have increased its beneficial ownership in the Company by more than 1% of the outstanding Shares or shall have filed a Notification and Report Form under the HSR Act or made a public announcement reflecting an intent to acquire the Company or any subsidiaries or material assets of the Company;

which, in the judgment of Omnicare or Purchaser in any such case, and regardless of the circumstances (including any action or inaction by Omnicare or Purchaser or any of their affiliates) giving rise to any such condition, makes it inadvisable to proceed with the Offer or with such acceptance for payment.

The satisfaction or existence of any of the foregoing conditions to the Offer will be determined by Omnicare and Purchaser in their reasonable discretion. The foregoing conditions are for the sole benefit of Omnicare and Purchaser and may be asserted by Omnicare or Purchaser regardless of the circumstances giving rise to any such condition or may be waived (to the extent legally permissible) by Omnicare or Purchaser in whole or in part at any time and from time to time in their sole discretion. The failure by Omnicare or Purchaser at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right; the waiver of any such right with respect to particular facts and other circumstances shall not be deemed a waiver with respect to any other facts and circumstances; and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time. Any determination by Omnicare or Purchaser concerning the events described in “The Offer—Conditions to the Offer” will be final and binding on all parties.

16. Certain Legal Matters; Regulatory Approvals.

General. We are not aware of any governmental license or regulatory permit that appears to be material to the Company’s business that might be adversely affected by our acquisition of Shares pursuant to the Offer or, except as set forth below, of any approval or other action by any government or governmental administrative or regulatory authority or agency, domestic or foreign, that would be required for our acquisition or ownership of Shares pursuant to the Offer. Should any such approval or other action be required, we currently contemplate that, such approval or other action will be sought. There can be no assurance that any such approval or other action, if needed, would be obtained (with or without substantial conditions) or that if such approvals were not obtained or such other actions were not taken adverse consequences might not result to the Company’s business or certain parts of the Company’s, Omnicare’s, Purchaser’s or any of their respective subsidiaries’ businesses might not have to be disposed of or held separate, any of which could cause us to elect to terminate the Offer without the purchase of Shares thereunder. Our obligation under the Offer to accept for payment and pay for Shares is subject to certain conditions. See “The Offer—Conditions to the Offer.”

State Takeover Laws. The Pennsylvania Takeover Disclosure Law (“PTDL”) purports to regulate certain attempts to acquire a corporation which (i) is organized under the laws of Pennsylvania or (ii) has its principal place of business and substantial assets located in Pennsylvania. The PTDL requires, among other things, that the offeror, 20 days prior to any takeover offer, file a registration statement for the takeover offer with the Pennsylvania Securities Commission (the “PSC”) and publicly disclose the offering price of the disclosed offer.

33

However, in Crane Co. v. Lam, 509 F. Supp. 782 (E.D. Pa. 1981), the United States District Court for the Eastern District of Pennsylvania preliminarily enjoined, on grounds arising under the United States Constitution, enforcement of at least the portion of the PTDL involving the pre-offer waiting period thereunder. Information regarding the Offer will be filed with the PSC and 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.

Chapter 25 of the PBCL contains provisions relating generally to takeovers and acquisitions of certain publicly owned Pennsylvania corporations such as the Company that have a class or series of shares entitled to vote generally in the election of directors of a corporation registered under the Exchange Act (a “registered corporation”). The following discussion is a general and highly abbreviated summary of certain features of such chapter, is not intended to be complete or to completely address potentially applicable exceptions or exemptions, and is qualified in its entirety by reference to Chapter 25 of the PBCL.

In addition to other provisions not applicable to the Offer or the Proposed Merger, Subchapter 25D of the PBCL includes provisions requiring approval of a merger of a registered corporation with an “interested shareholder” or in which the “interested shareholder” is treated differently from other shareholders, by the affirmative vote of the shareholders entitled to cast at least a majority of the votes that all shareholders other than the interested shareholder are entitled to cast with respect to the transaction without counting the votes of the interested shareholder. This disinterested shareholder approval requirement is not applicable to a transaction (i) approved by a majority of disinterested directors, (ii) in which the consideration to be received by shareholders is not less than the highest amount paid by the interested shareholder in acquiring his shares or (iii) effected without submitting the merger to a vote of shareholders as permitted in Section 1924(b)(1)(ii) of the PBCL. Purchaser currently believes that the disinterested shareholder approval requirement of Subchapter 25D will not be applicable to the Proposed Merger because the consideration to be received by shareholders in the Proposed Merger will not be less than the highest amount paid by Purchaser in acquiring its Shares.

Subchapter 25E of the PBCL provides that, in the event that Purchaser (or a group of related persons, or any other person or group of related persons) were to acquire shares representing at least 20% of the voting power of the Company, in connection with the Offer or otherwise (a “Control Transaction”), shareholders of the Company would have the right to demand “fair value” of such shareholders’ shares and to be paid such fair value upon compliance with the requirements of Subchapter 25E. Under Subchapter 25E, “fair value” may not be less than the highest price per share paid by the controlling person or group at any time during the 90-day period ending on and including the date of the Control Transaction, plus an increment, if any, representing any value, including, without limitation, any proportion of value payable for acquisition of control of the Company, that may not be reflected in such price. The Company has opted out of Subchapter 25E in its Amended and Restated Articles of Incorporation.

Subchapter 25F of the PBCL prohibits under certain circumstances certain “business combinations,” including mergers and sales or pledges of significant assets, of a registered corporation with an “interested shareholder” for a period of five years. Subchapter 25F exempts, among other things, business combinations approved by (i) the board of directors prior to a shareholder becoming an interested shareholder, (ii) the affirmative vote of the holders of shares entitling such holders to cast a majority of the votes that all shareholders would be entitled to cast in an election of directors of the corporation, not including any voting shares beneficially owned by the interested shareholder or any affiliate or associate of such interested shareholder, at a meeting called for such purpose no earlier than three months after the interested shareholder became the beneficial owner, directly or indirectly, of shares entitling the interested shareholder to cast at least 80% of the votes that all shareholders would be entitled to cast in an election of directors of the corporation, and if certain “fair price” conditions are met or (iii) by the affirmative vote of all of the holders of all of the outstanding common shares. The Offer is conditioned upon, among other things, Omnicare being satisfied, in its reasonable discretion, that the provisions of Subchapter 25F of the PBCL are inapplicable to and do not otherwise restrict the Offer and the Proposed Merger.

34

Subchapter 25G of the PBCL, relating to “control-share acquisitions,” prevents under certain circumstances the owner of a control-share block of shares of a registered corporation from voting such shares unless a majority of both the “disinterested” shares and all voting shares approve such voting rights. Failure to obtain such approval may result in a forced sale by the control-share owner of the control-share block to the corporation at a possible loss. The Company has opted out of Subchapter 25G in its Amended and Restated Articles of Incorporation.

Subchapter 25H of the PBCL, relating to disgorgement by certain controlling shareholders of a registered corporation following attempts to acquire control, provides that under certain circumstances any profit realized by a controlling person from the disposition of shares of the corporation to any person (including to the corporation under Subchapter 25G or otherwise) will be recoverable by the corporation. The Company has opted out of Subchapter 25H in its Amended and Restated Articles of Incorporation.

Subchapter 25I of the PBCL entitles “eligible employees” of a registered corporation to a lump sum payment of severance compensation under certain circumstances if the employee is terminated, other than for willful misconduct, within 90 days before voting rights lost as a result of a control-share acquisition are restored by a vote of disinterested shareholders. Subchapter 25J of the PBCL provides protection against termination or impairment under certain circumstances of “covered labor contracts” of a registered corporation as a result of a “business combination transaction” if the business operation to which the covered labor contract relates was owned by the registered corporation at the time voting rights are restored by shareholder vote after a control-share acquisition. The Company has opted out of Subchapters 25I and 25J in its Amended and Restated Articles of Incorporation.

Section 2504 of the PBCL provides that the applicability of Chapter 25 of the PBCL to a registered corporation having a class or series of shares entitled to vote generally in the election of directors registered under the Exchange Act or otherwise satisfying the definition of a registered corporation under Section 2502(1) of the PBCL will terminate immediately upon the termination of the status of the corporation as a registered corporation. The purchase of a substantial number of Shares pursuant to the Offer may result in the Company being able to terminate its Exchange Act registration, although Purchaser has no current intention to do so prior to the Effective Time.

A number of other states throughout the United States have enacted takeover statutes that purport, in varying degrees, to be applicable to attempts to acquire securities of corporations that are incorporated or have assets, shareholders, executive offices or places of business in such states. To the extent that these state takeover statutes purport to apply to the Offer or the Proposed Merger, we believe that those laws conflict with U.S. federal law and are an unconstitutional burden on interstate commerce. In 1982, the Supreme Court of the United States, in Edgar v. MITE Corp., invalidated on constitutional grounds the Illinois Business Takeover Statute, which, as a matter of state securities law, made takeover of corporations meeting certain requirements more difficult. The reasoning in that decision is likely to apply to certain other state takeover statutes. In 1987, however, in CTS Corp. v. Dynamics Corp. of America, the Supreme Court of the United States held that the State of Indiana could as a matter of corporate law and, in particular, those aspects of corporate law concerning corporate governance, constitutionally disqualify a potential acquiror from voting on the affairs of a target corporation without the prior approval of the remaining shareholders, as long as those laws were applicable only under certain conditions. Subsequently, in TLX Acquisition Corp. v. Telex Corp., a federal district court in Oklahoma ruled that the Oklahoma statutes were unconstitutional insofar as they apply to corporations incorporated outside Oklahoma, because they would subject those corporations to inconsistent regulations. Similarly, in Tyson Foods, Inc. v. McReynolds, a federal district court in Tennessee ruled that four Tennessee takeover statutes were unconstitutional as applied to corporations incorporated outside Tennessee. This decision was affirmed by the United State Court of Appeals for the Sixth Circuit. In December 1988, a federal district court in Florida held, in Grand Metropolitan PLC v. Butterworth, that the provisions of the Florida Affiliated Transactions Act and Florida Control Share Acquisition Act were unconstitutional as applied to corporations incorporated outside of Florida.

35

Except as described herein, we have not attempted to comply with any state takeover statutes in connection with this Offer or the Proposed Merger. We reserve the right to challenge the validity or applicability of any state law allegedly applicable to the Offer or the Proposed Merger, and nothing in this Offer to Purchase nor any action that we take in connection with the Offer is intended as a waiver of that right. In the event that it is asserted that one or more takeover statutes apply to the Offer or the Proposed Merger, and it is not determined by an appropriate court that the statutes in question do not apply or are invalid as applied to the Offer or the Proposed Merger, as applicable, we may be required to file certain documents with, or receive approvals from, the relevant state authorities, and we might be unable to accept for payment or purchase Shares tendered in the Offer or be delayed in continuing or consummating the Offer. In that case, we may not be obligated to accept for purchase, or pay for, any Shares tendered. See “The Offer—Conditions to the Offer.”

Antitrust. Under the HSR Act, and the rules that have been promulgated thereunder by the Federal Trade Commission (the “FTC”), certain acquisition transactions may not be consummated unless certain information has been furnished to the Antitrust Division of the Department of Justice (the “Antitrust Division”) and the FTC and certain waiting period requirements have been satisfied. The purchase of Shares pursuant to the Offer is subject to such requirements.

Pursuant to the requirements of the HSR Act, Omnicare intends to file a Notification and Report Form with respect to the Offer and the Proposed Merger with the Antitrust Division and the FTC on or about June 4, 2004. As a result, we anticipate that the waiting period applicable to the purchase of Shares pursuant to the Offer is scheduled to expire at 11:59 p.m., New York City time, on or about June 21, 2004. However, prior to such time, the Antitrust Division or the FTC may extend the waiting period by requesting additional information or documentary material relevant to the Offer from us. If such a request is made, the waiting period will be extended until 11:59 p.m., New York City time, on the tenth day after our substantial compliance with such request. Thereafter, such waiting period can be extended only by court order or as agreed to by Omnicare. A request will be made pursuant to the HSR Act for early termination of the waiting period applicable to the Offer. There can be no assurance, however, that the HSR Act waiting period will be terminated early.

Shares will not be accepted for payment or paid for pursuant to the Offer until the expiration or earlier termination of the applicable waiting period under the HSR Act. See “The Offer—Conditions to the Offer.” Subject to certain circumstances described in “The Offer—Extension of Tender Period; Termination; Amendment,” any extension of the waiting period will not give rise to any withdrawal rights not otherwise provided for by applicable law. See “The Offer—Withdrawal Rights.” If our acquisition of Shares is delayed pursuant to a request by the Antitrust Division or the FTC for additional information or documentary material pursuant to the HSR Act, the Offer may be extended.

The Antitrust Division and the FTC frequently scrutinize the legality under the antitrust laws of transactions such as our acquisition of Shares pursuant to the Offer. At any time before or after consummation of any such transactions, the Antitrust Division or the FTC could take such action under the antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the purchase of Shares pursuant to the Offer or seeking divestiture of the Shares so acquired or divestiture of Omnicare’s or the Company’s material assets. Private parties (including individual states) may also bring legal actions under the antitrust laws. Based on an examination of the publicly available information relating to the businesses in which the Company is engaged, we do not believe that the consummation of the Offer will result in a violation of any applicable antitrust laws. However, there can be no assurance that a challenge to the Offer on antitrust grounds will not be made, or if such a challenge is made, what the result will be. See “The Offer—Conditions to the Offer” for certain conditions to the Offer, including conditions with respect to litigation and certain governmental actions.

Dissenters’ Rights. Shareholders do not have dissenters’ rights as a result of the Offer. However, if the Proposed Merger is consummated, shareholders may have certain rights pursuant to the provisions of Subchapter 15D of the PBCL or any successor or replacement provision to dissent and demand appraisal of, and to receive payment in cash of the fair value of, their Shares. Shareholders will only be entitled to dissenters’ rights in the

36

Proposed Merger 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 less than 2,000 persons or (ii) Purchaser 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 comply with the statutory procedures concerning the right of shareholders to dissent from the Proposed Merger and dissenters’ rights are applicable, your Shares will not be converted into the right to receive the per Share Merger Consideration and you will instead be entitled to receive either the amount that the surviving corporation determines 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. Any such judicial determination of the fair value of the Shares could be based upon considerations other than or in addition to the Merger Consideration or the market value of the Shares, including asset values and the investment value of the Shares. The fair value so determined could be more or less than the per Share Merger Consideration.

In circumstances in which dissenters’ rights are applicable, if any shareholder who demands appraisal but fails to perfect, or effectively withdraws or loses his right to appraisal and payment, in accordance with the procedures of Subchapter 15D of the PBCL, the Shares of such shareholder will be converted into the per Share Merger Consideration in accordance with the Offer.

The foregoing discussion is not a complete statement of law pertaining to dissenters’ rights under the PBCL and is qualified in its entirety by the full text of Subchapter 15D of the PBCL.

Failure to follow the steps required by Subchapter 15D of the PBCL for perfecting dissenters’ rights may result in loss of such rights. The preservation and exercise of appraisal rights require strict adherence to the applicable provisions of the PBCL.

Going Private Transactions. The SEC has adopted Rule 13e-3 under the Exchange Act which is applicable to certain “going private” transactions and which may under certain circumstances be applicable to the Proposed Merger or another business combination following the purchase of Shares pursuant to the Offer in which Purchaser seeks to acquire the remaining Shares not held by it. Purchaser believes, however, that Rule 13e-3 will not be applicable to the Proposed Merger because it is anticipated that the Proposed Merger would be effected within one year following consummation of the Offer and in the Proposed Merger shareholders would receive the same price per Share as paid in the Offer. If Rule 13e-3 were applicable to the Proposed Merger, it would require, among other things, that certain financial information concerning the Company, and certain information relating to the fairness of the proposed transaction and the consideration offered to minority shareholders in such a transaction, be filed with the SEC and disclosed to minority shareholders prior to consummation of the transaction. The purchase of a substantial number of Shares pursuant to the Offer may result in the Company being able to terminate its Exchange Act registration, although Purchaser has no current intention to do so prior to the Effective Time. See “The Offer—Effect of the Offer on the Market for the Common Stock; Registration under the Exchange Act.” If such registration were terminated, Rule 13e-3 would be inapplicable to any such future Proposed Merger or such alternative transaction.

Article IX of the Amended and Restated Articles of Incorporation. Article IX of the Amended and Restated Articles of Incorporation of the Company provides that any business combination, unless approved by the affirmative vote of 75% of the entire Board, must be approved by at least 80% of outstanding voting stock entitled to vote on the election of directors, voting together as a single class. Such business combinations include: (i) any merger or consolidation of the Company or any corporation of which the shares having a majority of the general voting power in electing the board of directors are, at the time as of which any determination is being made, owned by the Company either directly or indirectly, (ii) any sale, lease, exchange, transfer or other disposition of all or substantially all of the assets of the Company and its subsidiaries, excluding financing transactions, (iii) the adoption of any plan or proposal for the liquidation or dissolution of the Company and (iv) any reclassification of securities, including reverse stock splits, or recapitalization of the Company, or any

37

merger or consolidation of the Company with any subsidiary. If the Minimum Condition is satisfied Omnicare believes that Article IX of the Amended and Restated Articles of Incorporation should not prohibit consummation of the Offer and the Proposed Merger.

17. Fees and Expenses.

Lazard Frères & Co. LLC (“Lazard”) and Lehman Brothers Inc. (“Lehman Brothers”) are acting as the Dealer Managers in connection with the Offer and as financial advisors to Omnicare in connection with the Offer and the Proposed Merger. Under separate engagement letters with Lazard and Lehman Brothers, Omnicare has agreed to pay each of Lazard and Lehman Brothers customary fees for its financial advisory services in connection with the Offer and the Proposed Merger. 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.

The Information Agent may contact holders of Shares by mail, telephone, telex, telegraph and personal interview and may request brokers, dealers and other nominee shareholders to forward material relating to the Offer to beneficial owners of Shares.

We have retained D.F. King & Co. (“D.F. King”) to advise Omnicare in connection with this Offer. We will pay D.F. King reasonable and customary compensation for its services in connection with the Offer, will reimburse D.F. King for its reasonable out-of-pocket expenses and will indemnify D.F. King against certain liabilities and expenses, including certain liabilities under the U.S. federal securities laws.

Except as set forth above, we will not pay any fees or commissions to any broker, dealer or other person for soliciting tenders of Shares pursuant to the Offer. We will reimburse brokers, dealers, commercial banks and trust companies and other nominees, upon request, for customary clerical and mailing expenses incurred by them in forwarding offering materials to their customers.

18. Miscellaneous.

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 this Offer to Purchase or in the related Letter of Transmittal and, if given or made, such information or representation must not be relied upon as having been authorized.

We have filed with the SEC a Tender Offer Statement on Schedule TO, together with exhibits, pursuant to the Exchange Act Rule 14d-3 furnishing certain additional information with respect to the Offer. The Schedule TO and any amendments thereto, including exhibits, may be examined and copies may be obtained from the offices of the SEC in the manner set forth in “The Offer—Certain Information Concerning the Company—Available Information” of this Offer to Purchase.

NOTE:    SIGNATURES MUST BE PROVIDED BELOW.

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 $30.00 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, receipt of which is hereby acknowledged, and in this 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, 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 “The Offer—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, in the case of Shares tendered by book-entry transfer, by credit to the account at the Book-Entry Transfer Facility). 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.

SPECIAL PAYMENT INSTRUCTIONS (See Instructions 1, 5, 6 and 7) To be completed ONLY if the check for the purchase price of Share Certificates purchased (less the amount of any tax required to be withheld) or certificates for Shares not tendered or not purchased are to be issued in the name of someone other than the undersigned.

INSTRUCTIONS

FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

1.    Guarantee of Signatures.    Except as otherwise provided below, all signatures on this 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 Letter of Transmittal need not be guaranteed (i) if this 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 Letter of Transmittal or (ii) if such Shares are tendered for the account of an Eligible Institution. See Instruction 5.

2.    Delivery of Letter of Transmittal and Shares.    This 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 “The Offer—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 Letter of Transmittal (or a manually signed facsimile thereof) and any other documents required by this 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 Letter of Transmittal by the Expiration Date (as defined in the Offer to Purchase). 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 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 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 Letter of Transmittal (or a manually signed facsimile thereof), and any other documents required by this Letter of Transmittal, must be received by the Depositary within three business days of the date of execution of such Notice of Guaranteed Delivery, as provided in “The Offer—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 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).    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 of Shares Tendered.” In such case, a new certificate

6

for the remainder of the Shares represented by the old certificate will be sent to the person(s) signing this Letter of Transmittal, unless otherwise provided in the appropriate box on this 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 Letter of Transmittal; Stock Powers and Endorsements.    If this 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 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 Letters of Transmittal as there are different registrations of certificates.

If this 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 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 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 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 Letter of Transmittal or to the person(s) signing this Letter of Transmittal at an address other than that shown above, the appropriate boxes on this 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 income 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

7

shareholder and other payee must provide the Depositary with its correct taxpayer identification number (“TIN”) and certify that it is 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 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 Letter of Transmittal and the 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.

IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A MANUALLY SIGNED FACSIMILE THEREOF) TOGETHER WITH ANY SIGNATURE GUARANTEES, OR, IN THE CASE OF A BOOK-ENTRY TRANSFER, AN AGENT’S MESSAGE, AND ANY OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION DATE AND EITHER CERTIFICATES FOR TENDERED SHARES MUST BE RECEIVED BY THE DEPOSITARY OR SHARES MUST BE DELIVERED PURSUANT TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER, IN EACH CASE PRIOR TO THE EXPIRATION DATE, OR THE TENDERING SHAREHOLDER MUST COMPLY WITH THE PROCEDURES FOR GUARANTEED DELIVERY.

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 uses the numbers for identification purposes and to help verify the accuracy of tax returns. The IRS may also provide this information to the Department of Justice for civil and criminal litigation, and to cities, states, and the District of Columbia to carry out their tax laws. 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.

Notice of Offer to Purchase for Cash

All Outstanding Shares of

Common Stock

(including the Associated Preferred Stock Purchase Rights)

of

NeighborCare, Inc.

at

$30.00 Net Per Share in Cash

by

Nectarine Acquisition Corp.,

a wholly owned subsidiary of

Omnicare, Inc.

Nectarine Acquisition Corp., a Delaware corporation (“Purchaser”) and a wholly owned subsidiary of Omnicare, Inc., a Delaware corporation (“Omnicare”), is offering to purchase all of the outstanding shares of common stock, par value $0.02 per share, including the Associated Preferred Stock Purchase Rights (the “Rights” and such shares together with the Rights, the “Shares”), of NeighborCare, Inc., a Pennsylvania corporation (the “Company”), at a price of $30.00 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, and in the related Letter of Transmittal (which, as amended and supplemented from time to time, together constitute the “Offer”). All capitalized terms used but not otherwise defined herein shall have the meaning given to them in the Offer to Purchase.

THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M.,

NEW YORK CITY TIME, ON JULY 7, 2004, UNLESS THE OFFER IS EXTENDED.

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 then-outstanding Share that is not owned by Omnicare, Purchaser or other subsidiaries of Omnicare (other than Shares owned by the Company or held by shareholders who properly exercise their appraisal rights, if any, under the Pennsylvania Business Corporation Law (the “PBCL”)) 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.

The Offer is conditioned upon, among other things, (1) there being validly tendered and not properly withdrawn prior to 5:00 P.M., New York City time, on July 7, 2004, or the latest time and date at which the Offer, if extended by Purchaser, shall expire (such time being the “Expiration Date”), 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, (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 PBCL does not otherwise restrict the Offer and the Proposed Merger or any subsequent business combination involving the Company and Omnicare, (3) all waiting periods under applicable antitrust laws, including the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, having expired or been terminated, (4) the Company’s board of directors redeeming 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, (5) Omnicare having available to it proceeds of the financings contemplated by its existing commitment letter 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 and (6) 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 expected economic value to Omnicare of the acquisition of the Company.

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 amending the number of Shares to be purchased and amending the purchase price) upon entering into a merger agreement with the Company or (ii) negotiate a merger agreement with the Company that does not involve a tender offer, pursuant to which merger agreement Purchaser would terminate the Offer and the Shares would, upon consummation of the merger contemplated by such merger agreement, be converted into cash, common stock of Omnicare and/or other securities in such amounts as are negotiated by Omnicare and the Company.

For purposes of the Offer, Purchaser shall be deemed to have accepted for payment tendered Shares when, as and if Purchaser gives oral or written notice of its acceptance to The Bank of New York (the “Depositary”). Purchaser will pay for Shares accepted for payment pursuant to the Offer by depositing the purchase price with the Depositary. The Depositary will act as agent for all tendering shareholders for the purpose of receiving payments from Purchaser and transmitting such payments to tendering shareholders whose Shares have been accepted for payment. Under no circumstances will interest be paid on the purchase price for Shares pursuant to the Offer, regardless of any delay in making such payment. If Omnicare increases the consideration to be paid for Shares, Omnicare will pay such increased consideration for all Shares purchased pursuant to the Offer. In all cases, payment for Shares tendered and accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of (i) certificates for such Shares or timely confirmation of a book-entry transfer of such Shares into the Depositary’s account at the Book-Entry Transfer

2

Facility, (ii) a properly completed and duly executed Letter of Transmittal and (iii) any other required documents. Accordingly, payment may be made to tendering shareholders at different times if delivery of the Shares and other required documents occurs at different times.

Subject to the applicable rules and regulations of the Securities and Exchange Commission, Purchaser reserves the right, in its sole discretion, at any time and from time to time, (i) to extend the period of time during which the Offer is open, and thereby delay acceptance of, and the payment for, Shares and (ii) to amend the Offer in any other respect, by giving oral or written notice of such extension or amendment to the Depositary. Any such extension or amendment will be followed as promptly as practicable by public announcement thereof and, in the case of such extension, such announcement will be made no later than 9:00 a.m., New York City time on the next business day after the previously scheduled Expiration Date.

Purchaser does not currently intend to include a subsequent offering period in the Offer, although it reserves the right to do so in its sole discretion. Pursuant to Rule 14d-7 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), 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.

Tendering shareholders may withdraw tenders of Shares made pursuant to the Offer at any time prior to the Expiration Date. Thereafter, such tenders are irrevocable, except that they may be withdrawn after August 2, 2004 unless such Shares are accepted for payment as provided in the Offer to Purchase. If Purchaser extends the period of time during which the Offer is open, is delayed in accepting Shares for payment or paying for Shares pursuant to the Offer for any reason, or is unable to accept Shares for payment pursuant to the Offer for any reason, then, without prejudice to Purchaser’s rights under the Offer, the Depositary may, on Purchaser’s behalf, retain all Shares tendered, and such Shares may not be withdrawn except as otherwise provided in the Offer to Purchase.

To withdraw tendered Shares, a written or facsimile transmission notice of withdrawal with respect to the Shares must be timely received by the Depositary at one of its addresses set forth on the back cover of the Offer to Purchase, and the notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn and the number of Shares to be withdrawn and the name of the registered holder of Shares, if different from that of the person who tendered such Shares. If the Shares to be withdrawn have been delivered to the Depositary, a signed notice of withdrawal with (except in the case of Shares tendered by an Eligible Institution) signatures guaranteed by an Eligible Institution must be submitted prior to the release of such Shares. In addition, such notice must specify, in the case of Shares tendered by delivery of certificates, the name of the registered holder (if different from that of the tendering shareholder) and the serial numbers shown on the particular certificates evidencing the Shares to be withdrawn or, in the case of Shares tendered by book-entry transfer, the name and number of the account at the Book-Entry Transfer Facility to be credited with the withdrawn Shares.

Omnicare news release

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

Attn: David W. Froesel, Jr.

Senior Vice President and

Chief Financial Officer

Ladies and Gentlemen:

This commitment letter agreement (together with all exhibits and schedules hereto, the “Commitment Letter”) will confirm the understanding and agreement among JPMorgan Chase Bank (“JPMCB”), J.P. Morgan Securities Inc. (“JPMorgan”), Lehman Commercial Paper Inc., (“LCPI”), Lehman Brothers Inc. (“Lehman Brothers”), SunTrust Bank (“SunTrust”), SunTrust Capital Markets, Inc. (“SunTrust Capital Markets”) (Lehman Brothers, JPMorgan and SunTrust Capital Markets, collectively, are exclusive joint lead book-runners and exclusive joint lead arrangers, the “Joint Lead Arrangers”), Canadian Imperial Bank of Commerce (“CIBC”), CIBC World Markets Corp. (“CIBC World Markets”), Merrill Lynch Bank USA (“Merrill Lynch”), Merrill Lynch, Pierce, Fenner & Smith Incorporated (“MLPFS”) and Omnicare, Inc., a Delaware corporation (together with each of its subsidiaries, the “Company”), in connection with the proposed financing for the acquisition of all of the issued and outstanding common stock of NeighborCare, a Pennsylvania corporation (the “Target” and, together with each of its subsidiaries, the “Acquired Business”). We understand that the Company may acquire all of the issued and outstanding common stock of the Target (the “Shares”) pursuant to a cash tender offer (the “Tender Offer”) by a wholly-owned subsidiary of the Company (the “Offer Subsidiary”) for all of the outstanding Shares, but for at least the number of outstanding Shares necessary to meet the Minimum Condition (as defined below), which Tender Offer would be expected to be

1

followed by a merger (the “Merger”) of the Offer Subsidiary with and into the Target. You have further advised us that in lieu of the Tender Offer and Merger, you may sign an agreement to acquire the Shares (an “Acquisition Agreement”). The Tender Offer and the Merger (or alternatively, the consummation of the acquisition of all of the Shares pursuant to an Acquisition Agreement) are sometimes collectively referred to in this Commitment Letter as the “Acquisition”.

You have advised us that the total funds needed to finance the Acquisition will be approximately $1.9 billion consisting of the following uses: (i) $1.335 billion for the acquisition of all of the issued and outstanding common stock of the Acquired Business, (ii) $250.0 million for the purchase of the 6.875% senior subordinated notes due 2013 (the “6.875% Notes”) of the Acquired Business, (iii) $151.8 million for the refinancing of the existing term loan indebtedness of the Company, (iv) approximately $110.0 million for the refinancing of the existing revolving credit facility of the Company (based on the amount outstanding under such revolving credit facility as of the date hereof), (v) $33.8 million for the estimated premium payable in connection with the tender for the 6.875% Notes and (vi) $53.7 million for the estimated fees and expenses of the Company. Such funds will be provided from the following sources: (i) approximately $134.3 million (as such amount may be increased to the extent the amount outstanding under the Company’s existing revolving credit facility on the Closing Date exceeds $110.0 million or decreased to the extent the amount under the Company’s existing revolving credit facility on the Closing Date is less than $110.0 million, such adjusted amount, the “Initial Revolver Draw Amount”) of borrowings by the Company under a $600.0 million Revolving Credit Facility, (ii) $700.0 million of borrowings by the Company under a Senior Term Loan Facility and (iii) $1.1 billion of borrowings by the Company under a 364-Day Facility (collectively, the “Credit Facilities”). Following the consummation of the Acquisition, the Company and its subsidiaries will not have any debt outstanding except as described in this paragraph and the debt set forth on Part 1 of Schedule 1 hereto. As used below, the defined term “Company” shall mean both the Company prior to the Acquisition and the Company together with the Acquired Business, after giving effect to the Acquisition.

You have also advised us that the Tender Offer will be subject to a condition that the Target’s stockholders shall have validly tendered and shall have not properly withdrawn prior to the expiration of the Tender Offer that number of Shares representing, together with the Shares owned by the Company, at least 80% of the total voting power of all the outstanding securities of the Target entitled to vote generally in the election of directors or in a merger, calculated on a fully diluted basis after consummation of the Tender Offer (the “Minimum Condition”) and that if the Tender Offer is consummated on a date prior to the date on which the Merger is consummated, the total funds needed to finance the Tender Offer will be $1369.9 million (assuming 80.0% of the Shares are tendered) consisting of the following uses: (i) $1068.1 million for the acquisition of 80.0% of the Shares, (ii) $151.8 million for the refinancing of the existing term loan indebtedness of the Company, (iii) $110.0 million for the refinancing of the existing revolving credit facility of the Company and (iv) $40.0 million for the estimated fees and expenses of the Company. We understand that the existing debt of the Acquired Business will not be refinanced until the consummation of the Merger. We understand that the funds needed to finance the Tender Offer will be provided from the following sources: (i) the Initial Revolver Draw Amount of borrowings by the Company under the $600.0 million Revolving Credit Facility, (ii) $700.0 million of borrowings by the Company under the Senior Term Loan Facility and (iii) at least $535.6 million of borrowings by the Company under the $1.1 billion 364-Day Facility. Following the consummation of the Tender Offer, but not the Merger, the Company and its subsidiaries will not have any debt outstanding except as described in this paragraph and the debt set forth on Part 2 of Schedule 1 hereto.

I.      Parties
Borrower	The Company.
Guarantors	The Company’s direct and indirect domestic subsidiaries which, together with the Company’s assets and revenues, account for at least 90% of the Company’s and its Subsidiaries’ consolidated assets and revenues (the “Guarantors”; the Company and the Guarantors, collectively, the “Credit Parties”); provided that the Joint Lead Arrangers may agree that the Target and its Subsidiaries shall not be required to become Guarantors until 30 days after the consummation of the Merger.
Joint Lead Arrangers and Joint Lead Book-Runners	JPMorgan, Lehman Bothers and SunTrust Capital Markets (in such capacity, the “Joint Lead Arrangers”).
Co-Syndication Agents	JPMorgan and Lehman Brothers (in such capacities, the “Co-Syndication Agents”).

Co-Documentation Agents	CIBC World Markets and MLPFS (in such capacities, the “Co-Documentation Agents”)
Senior Lenders	A syndicate of banks, financial institutions and other entities arranged by the Joint Lead Arrangers and reasonably satisfactory to the Company (collectively, the “Senior Lenders”).

A-1

II.      Types and Amounts of Credit Facilities
Senior Term Loan Facility	A five-year term loan facility (the “Senior Term Loan Facility”) in an aggregate principal amount equal to $700.0 million (the loans thereunder, the “Term Loans”). The Term Loans shall be repayable in quarterly installments beginning on the first full fiscal quarter commencing after the Closing Date in an aggregate principal amount for each year following the Closing Date equal to the amount set forth opposite such year below (with the installments in each such year being equal in amount): Year 1        10% Year 2        15% Year 3        15% Year 4        20% Year 5        40%
Availability	The Term Loans shall be made in a single drawing on the Closing Date.
Purpose	The proceeds of the Term Loans shall be used to finance the Acquisition (including the Tender Offer), refinance the Company’s existing debt and to pay related fees and expenses.
364-Day Facility	A 364-day loan facility (the “364-Day Facility”) in an aggregate principal amount equal to $1.1 billion (the loans thereunder, the 364-Day Loans”). The 364-Day Loans shall mature 364 days after the Closing Date and shall not be subject to interim scheduled amortization.
Availability	The 364-Day Loans shall be available as follows: (a) if the Merger is not consummated on the Closing Date, in up to two drawings, one on the Closing Date and one on the date of consummation of the Merger, in amounts to be determined and (b) if the Merger is consummated on the Closing Date, in a single drawing on the Closing Date.
Purpose	The proceeds of the 364-Day Loans shall be used to finance the Acquisition (including the Tender Offer), refinance the Company’s existing debt and to pay related fees and expenses.

A-2

Revolving Credit Facility	A five-year revolving credit facility (the “Revolving Credit Facility” and together with the Senior Term Loan Facility and the 364-Day Facility, the “Credit Facilities”) in an aggregate principal amount equal to $600.0 million (the loans thereunder, the “Revolving Credit Loans” and, collectively with the Term Loans and the 364-Day Loans, the “Loans”).
Availability	The Revolving Credit Facility shall be available on a revolving basis during the period commencing on the Closing Date and ending on the fifth anniversary thereof (the “Revolving Credit Termination Date”).
Letters of Credit	A portion of the Revolving Credit Facility not in excess of $50.0 million shall be available for the issuance of letters of credit (the “Letters of Credit”) by one or more Senior Lenders to be selected in the syndication process (each such Senior Lender in such capacity, an “Issuing Lender”). The face amount of any outstanding Letters of Credit will reduce availability under the Revolving Credit Facility on a dollar-for-dollar basis. No Letter of Credit shall have an expiration date after the earlier of (i) one year after the date of issuance and (ii) five business days prior to the Revolving Credit Termination Date; provided that any Letter of Credit with a one-year tenor may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (ii) above).
	Drawings under any Letter of Credit shall be reimbursed by the Company (whether with its own funds or with the proceeds of Revolving Credit Loans) on the same business day. To the extent that the Company does not so reimburse the Issuing Lender, the Senior Lenders under the Revolving Credit Facility shall be irrevocably and unconditionally obligated to reimburse the Issuing Lender on a pro rata basis.

A-3

Swing Line Loans	A portion of the Revolving Credit Facility not in excess of $50.0 million shall be available for swing line loans (the “Swing Line Loans”) from a Senior Lender to be selected in the syndication process (in such capacity, the “Swing Line Lender”) on same-day notice. Any such Swing Line Loans will reduce availability under the Revolving Credit Facility on a dollar-for-dollar basis. Each Senior Lender under the Revolving Credit Facility shall acquire, under certain circumstances, an irrevocable and unconditional pro rata participation in each Swing Line Loan.
Maturity	The Revolving Credit Termination Date.
Purpose	Up to the Initial Revolver Draw Amount of the proceeds of the Revolving Credit Loans shall be used on the Closing Date to finance the Acquisition (including the Tender Offer) and to refinance the Company’s existing debt and, after the Closing Date, proceeds of the Revolving Credit Loans shall be used for general corporate purposes of the Company and its subsidiaries in the ordinary course of business.

Optional prepayments of the Term Loans shall be applied to the installments thereof ratably in accordance with the then outstanding amounts thereof and may not be reborrowed. Optional repayments of 364-Day Loans or Term Loans may not be reborrowed.
Mandatory Prepayments and Commitment Reductions	The 364-Day Loans shall be repaid with 100% of the net proceeds of any sale or issuance of equity by the Company (subject to customary exceptions) and 100% of the net proceeds of any incurrence of certain indebtedness by the Company or any of its subsidiaries.

On-Going Conditions	If the Merger is not consummated on the Closing Date, the second draw of the 364-Day Credit Facility is conditioned upon (i) the completion of the acquisition through the consummation of the Merger for an aggregate purchase price not exceeding $30.0 per share (based on the aggregate amount of shares outstanding on the date hereof), which purchase price may be changed with the consent of the Commitment Parties (such consent not to be unreasonably withheld) and (ii) the capital structure of each Credit Party after giving effect to the transactions occurring on such date being reasonably satisfactory to the Senior Lenders. The making of each extension of credit shall be conditioned upon (i) the accuracy in all material respects of all representations and warranties in the definitive financing documentation with respect to the Credit Facilities (the “Credit Documentation”) (including, without limitation, the material adverse change and litigation representations) and (ii) there being no default or event of default in existence at the time of, or after giving effect to the making of, such extension of credit.
V.      Certain Documentation Matters	The Credit Documentation shall contain representations, warranties, covenants and events of default substantially the same as those in the Company’s existing credit agreement, dated as of June 13, 2003, among the Company, JP Morgan Chase Bank, Lehman Commercial Paper Inc., Sun Trust Bank, as administrative agent, and the other parties signatory thereto (the “Existing Credit Agreement”), with such modifications and exceptions as necessary to permit consummation of the Tender Offer, the Merger and the Acquisition and, including, without limitation:

A-5

Representations and Warranties	Financial statements (including pro forma financial statements); absence of undisclosed material liabilities; no material adverse change; corporate existence; compliance with law; corporate power and authority; enforceability of Credit Documentation; no conflict with law or material contractual obligations; no material litigation; no default; ownership of property; taxes; Federal Reserve regulations; ERISA; Investment Company Act; subsidiaries; solvency; accuracy of disclosure; and status of the Credit Facilities as senior debt.

Negative Covenants	Limitations on: liens; contingent obligations; mergers, consolidations, liquidations and dissolutions; sales of assets; investments, loans and advances; optional payments and modifications of subordinated and other debt instruments; transactions with affiliates and changes in lines of business (in each case, with exclusions to the extent necessary to consummate the acquisition and comply with margin lending regulations and certain other exceptions to be agreed upon).
Events of Default	Nonpayment of principal when due; nonpayment of interest, fees or other amounts after a grace period to be agreed upon; material inaccuracy of representations and warranties; violation of covenants (subject, in the case of certain covenants, to a grace period to be agreed upon); cross-default; bankruptcy events; certain ERISA events; material judgments or environmental liabilities; actual or asserted invalidity of any guarantee; and a change of control (the definition of which is to be agreed).

The Incremental Facility will be effected as a term loan facility which will not mature earlier than six-months after the maturity of the Term Loans and have an average life to maturity shorter than the remaining amortization of the Term Loan. The Incremental Facility (i) will rank pari passu in right of repayment with the other Credit Facilities and (ii) except as set forth above, will be treated substantially the same as (and in any event no more favorably than) the Term Loan Facility. The Incremental Facility will be effected pursuant to an amendment to the Credit Documentation entered into among the Company, the Administrative Agent and Incremental Facility lenders, which will not require the consent of the other Senior Lenders and will contain customary mark-to-market terms. No Senior Lenders under the Credit Facilities will be required to commit to provide any portion of the Incremental Facility. The proceeds of the Incremental Facility will be used for the general corporate purposes of the Company.

A-7

	As used herein:

Commitment Fees	The Company shall pay a commitment fee calculated at the applicable rate set forth in Annex A-II, on the average daily unused portion of the Revolving Credit Facility and, if the Merger is not consummated on the Closing Date, the 364-Day Facility, payable quarterly in arrears.

	Swing Line Loans shall, for purposes of the commitment fee calculations only, not be deemed to be a utilization of the Revolving Credit Facility other than with respect to the Swing Line Lender.

Such commission shall be shared ratably among the Senior Lenders participating in the Revolving Credit Facility and shall be payable quarterly in arrears.
	In addition to letter of credit commissions, a fronting fee calculated at a rate per annum to be agreed upon by the Company and the Issuing Lender on the face amount of each Letter of Credit shall be payable quarterly in arrears to the Issuing Lender for its own account. In addition, customary issuance, amendment, payment and negotiation charges shall be payable to the Issuing Lender for its own account.
Default Rate	At any time when the Company is in default in the payment of any amount of principal due under the Credit Facilities, such amount shall bear interest at 2% above the rate otherwise applicable thereto. Overdue interest, fees and other amounts shall bear interest at 2% above the rate applicable to Base Rate Loans.
Rate and Fee Basis	All per annum rates shall be calculated on the basis of a year of 360 days (or 365 days, in the case of Base Rate Loans the interest rate payable on which is then based on the Prime Rate) and the actual number of days elapsed.

The credit rating in effect on any date for the purposes of this Schedule is that in effect at the close of business on such date. If at any time the Company has no Moody’s Rating or no S&P Rating, Level VI Status shall exist, provided that if either S&P or Moody’s shall no longer provide debt ratings for companies in the Company’s industry generally, the Company may substitute for either such rating organization another nationally recognized statistical rating organization, the corresponding ratings of which shall be used to determine the Company’s Status. If the Company is split-rated and the ratings differential is one level, the higher rating will apply. If the Company is split-rated and the ratings differential is two levels, the intermediate rating at the midpoint will apply. If the Company is split-rated and the ratings differential is more than two levels, the rating that is one level above the lower rating will apply.
