Re: NCS HealthCare, Inc.


Dear Mr. Gemunder:

         Omnicare, Inc. ("Omnicare" and sometimes "you" or "your") has expressed
an interest in a possible transaction (the "Transaction") with NCS HealthCare,
Inc. (including its subsidiaries and affiliates, the "Company"). You have
requested that the Company furnish you with certain information which the
Company may consider to be material and non-public, confidential or proprietary
in nature. In consideration for and as a condition to the Company's furnishing
access to such information as the Company, in its sole discretion, agrees to
deliver, provide or otherwise make available to Omnicare, you agree to the terms
and conditions set forth in this letter agreement. The Company may, in its sole
discretion, withhold information where it concludes that the disclosure of such
information would violate applicable law, breach a duty, subject the Company to
risk of a material penalty, or be detrimental to its interests.

1.   You and all of your partners, members, directors, officers, employees,
     agents, affiliates, advisors, accountants, bankers, attorneys, potential
     sources of financing and other similarly situated individuals or entities
     (collectively "Informed Parties") acknowledge the confidential, non-public
     and proprietary nature of the Confidential Information (as defined below)
     and agree to hold and keep all Confidential Information which is disclosed
     to you or any Informed Party pursuant to the terms of this letter agreement
     as confidential, regardless of whether such information is marked or
     otherwise identified as confidential.

2.   As used in this letter agreement, the term "Confidential Information" means
     and includes any and all information, in any form, hereafter disclosed, in
     any manner, to you or your Informed Parties concerning the Company or the
     Transaction regardless of whether such information is disclosed by the
     Company or by its advisors, agents or other representatives (collectively
     "Advisors"). The term "Confidential Information" also includes all notes,
     analyses, compilations, studies, interpretations or other documents
     prepared by you or Informed Parties which contain, reflect or are based
     upon, in whole or in part, any information disclosed to you or Informed
     Parties by or on behalf of the Company.

3.   The term "Confidential Information" does not include information which (a)
     is or becomes generally available to the public other than as a result of a
     disclosure by you or the Informed Parties in violation of this letter
     agreement, (b) is within your or the Informed Parties' possession from a
     source other than the Company; provided that such source was not known by
     you or the Informed Parties to be bound by any contractual, legal or
     fiduciary obligations of confidentiality to the Company with respect to
     such information, or (c) is or becomes available to you or the Informed
     Parties on a non-confidential basis from a source other than the Company or
     any of the Advisors; provided that such source is not known by you or your
     Informed Parties to be bound by any contractual, legal or fiduciary
     obligations of confidentiality to the Company with respect to such
     information.

4.   You and the Informed Parties acknowledge that any trade secrets of the
     Company, however documented, that may be disclosed to you or the Informed
     Parties are also entitled to any and all of the protections and benefits of
     all applicable state trade secret laws. If any information that the Company
     deems to be a trade secret is found by a court of competent jurisdiction
     not to be a trade secret for purposes of this letter agreement, such
     information will in any event still be considered Confidential Information
     for purposes of this letter agreement.

5.   To the extent that any Confidential Information may include materials
     subject to the attorney-client privilege, the Company is not waiving and
     will not be deemed to have waived or diminished its attorney work-product
     protections, attorney-client privileges or similar protections and
     privileges as a result of disclosing any Confidential Information
     (including Confidential Information related to pending or threatened
     litigation) to you or your Informed Parties, regardless of whether the
     Company has asserted or is or may be entitled to assert such privileges and
     protections. The parties (a) share a common legal and commercial interest
     in all such Confidential Information that is subject to such privileges and
     protections and (b) intend that such privileges and protections remain
     intact should either party become subject to any actual or threatened
     proceeding to which such Confidential Information covered by such
     protections and privileges relates. In furtherance of the foregoing, you
     shall not claim or contend, in proceedings involving either party, that the
     Company waived its attorney work-product protections, attorney-client
     privileges or similar protections and








Mr. Joel F. Gemunder
August 29, 2001
Page 3


     privileges with respect to any information, documents or other material not
     disclosed to you due to the Company disclosing Confidential Information
     (including Confidential Information related to pending or threatened
     litigation) to you.

6.   You agree that the Confidential Information (a) will be kept confidential
     by you and the Informed Parties and (b) without limiting the foregoing,
     will not be reproduced or disclosed, distributed or communicated, directly
     or indirectly, in whole or in part, by you or the Informed Parties to any
     person except with the specific prior written consent of the Company acting
     through its Board of Directors or except as expressly otherwise permitted
     by this letter agreement, provided, however, that you may make any such
     disclosure (i) if the disclosure is required to comply with law, but only
     to the extent necessary to comply (provided that, to the extent reasonably
     practicable, you have given notice to the Company prior to any such
     disclosure so that the Company may seek an appropriate protective order or
     other appropriate relief or waive compliance with the provisions of this
     letter agreement), and (ii) if the disclosure is required under the federal
     securities laws in connection with any offer by you to purchase any debt or
     equity securities of the Company (provided that you have given at least 24
     hours written notice to the Company of your termination of discussions with
     the Company relating to a possible Transaction prior to the disclosure
     contemplated by this clause (ii)). It is understood that you may disclose
     the Confidential Information to only those Informed Parties who (a) require
     such information for the purpose of evaluating a possible Transaction with
     the Company and (b) are informed by you of the confidential nature of the
     Confidential Information and the obligations of this letter agreement. You
     further agree that you and the Informed Parties will not use any of the
     Confidential Information for any reason or purpose other than to evaluate
     and to negotiate a possible Transaction with the Company. You also agree to
     be responsible for any breach of this letter agreement by the Informed
     Parties.

7.   You acknowledge that you are aware, and that you will advise the Informed
     Parties, that applicable securities laws impose restrictions on any person
     who has material, non-public information concerning a company, such as the
     Confidential Information, from purchasing or selling securities of such
     company or from communicating such information to any other person under
     circumstances in which it is reasonably foreseeable that such person is
     likely to purchase or sell such securities in reliance upon such
     information.

8.   Except as expressly permitted by Section 6 and except as expressly
     permitted by a definitive agreement with respect to the Transaction, if
     any, entered into between the parties, each of the Company and its Advisors
     and you and the Informed Parties agree not to disclose to any person the
     fact that the Confidential Information has been disclosed to you or the
     Informed Parties or that you or the Informed Parties have inspected any
     portion of the Confidential Information or that any discussions or
     negotiations are taking place concerning the Transaction; provided,
     however, either party may make such a disclosure if, and solely to the








Mr. Joel F. Gemunder
August 29, 2001
Page 4


     extent that, such party has determined, in connection with its outside
     counsel, that such a disclosure must be made in order to not commit a
     violation of law, and further provided, the party making such disclosure
     shall consult with the other party before making any such disclosure, and
     any such permitted disclosure shall not affect or impair such party's
     obligations of confidentiality with respect to the Confidential
     Information. Notwithstanding the foregoing, (i) the Company may disclose to
     (a) its creditors and/or their representatives and advisors and (b) to any
     party with which it is contractually obligated to do so pursuant to a
     written agreement in existence on the date hereof or entered into
     subsequent to the date hereof, and without limiting your rights under
     paragraph 6 of this letter agreement (ii) you may disclose to (a) any owner
     of the Company's bank debt or any debt security of the Company and/or their
     representatives and advisors (collectively, the "Debt Holders") and (b)
     AmerisourceBergen Corporation or any group or committee (whether ad hoc or
     formal) representing no less than one-third of the trade debt of the
     Company and/or their representatives and advisors (collectively, the "Trade
     Creditors" and, together with the Debt Holders, the "Creditors"), the fact
     that discussions are taking place concerning the Transaction and, in the
     case of the preceding clauses (i)(a), (ii)(a) and (ii)(b), the terms of
     such discussions or negotiations; provided that, in the case of the
     preceding clauses (ii)(a) and (ii)(b), you advise the Creditors of the
     confidential nature of the disclosed information and the obligations of
     this letter agreement and further provided that you will not be responsible
     for any breach of this letter agreement by such Creditors. You hereby
     represent that as of the date you sign this letter agreement, you are not
     aware of any facts or circumstances that exist that would require you to
     make such a disclosure in order to not commit a violation of law. The
     Company agrees to be responsible for any breach of this letter agreement by
     its Advisors.

9.   All requests by you or the Informed Parties for Confidential Information,
     meetings with the Company's personnel or Advisors or inspection of the
     Company's properties must be made to the Company's Board of Directors or
     the Chief Executive Officer of the Company.

10.  In the event that any party to this letter agreement becomes legally
     compelled (by oral questions, interrogatories, requests for information or
     documents, subpoena, civil or criminal investigative demand or similar
     process) to make any disclosure that is prohibited or otherwise constrained
     by this letter agreement (such party, a disclosing party), such disclosing
     party will provide the other party (the non-disclosing party) with prompt
     notice of such legal proceedings so that the non-disclosing party may seek
     an appropriate protective order or other appropriate relief or waive
     compliance with the provisions of this letter agreement. In the absence of
     a protective order or a waiver from the non-disclosing party, the
     disclosing party is permitted to disclose that portion (and only that
     portion) of the Confidential Information that the disclosing party is
     legally compelled to disclose; provided, however, that the disclosing party
     must use reasonable efforts to obtain reliable assurance that confidential
     treatment will be accorded by any person to whom any Confidential
     Information is disclosed.

11.  You understand, acknowledge and agree that the Company retains the right to
     determine, in its sole discretion, what information, properties and
     personnel it wishes to make available to you, and neither the Company nor
     any of its Advisors make any representation or warranty, express or
     implied, as to the accuracy or completeness of the Confidential
     Information. You further agree that neither the Company, nor any of its
     Advisors, shall have any liability to you or any Informed Party relating to
     or resulting from the use of the Confidential Information.

12.  You agree that, during the term of this letter agreement neither you nor
     any Informed Party will directly or indirectly, (a) induce or attempt to
     induce any employee of the Company or the Company's affiliates or
     subsidiaries to leave the employ of the Company or such affiliate or
     subsidiary, or (b) solicit for employment or as an independent contractor,
     or otherwise, any person who is an employee of the Company, or of the
     Company's affiliates or subsidiaries; provided, however, that the foregoing
     subsections (a) and (b) of this paragraph 12 will not prevent you from
     employing any such person who (i) contacts you on his or her own initiative
     without any direct or indirect solicitation by, or encouragement from, you
     (it being understood that general advertisements and other similar broad
     forms of solicitations shall not constitute direct or indirect solicitation
     hereunder) or (ii) has been terminated by the Company prior to commencement
     of employment discussions between you and such person.

13.  In the event that you determine that you no longer wish to proceed with the
     Transaction or upon written notice from the Company that it does not wish
     you to consider the Transaction any further, then (a) you (i) shall
     promptly deliver to the Company's Board of Directors all documents or other
     tangible materials disclosed by the Company or any of its Advisors to you
     or the Informed Parties constituting Confidential Information, together
     with all copies and summaries thereof in the possession or under the
     control of you or the Informed Parties and (ii) will destroy all materials
     generated by you or the Informed Parties that include or refer to any part
     of the Confidential Information, without retaining a copy of any such
     material or (b) alternatively, at your option, you will destroy all
     documents or other matters constituting Confidential Information in the
     possession or under the control of you or the Informed Parties. Any such
     destruction pursuant to the foregoing must be certified by an authorized
     officer of Omnicare in writing to the Company (and such certification shall
     include a list of the destroyed materials). Notwithstanding the foregoing,
     you may retain one copy of the Confidential Information in confidential
     restricted access files for use only in the event a dispute arises
     hereunder and only in connection with such dispute and you may retain such
     of the Confidential Information as shall have been incorporated into the
     records of your Board of Directors or the records of the Board of Directors
     of any of your subsidiaries.

14.  The Company reserves the right, in its sole discretion, to reject any and
     all proposals made by you or the Informed Parties with regard to a
     Transaction and to terminate discussions and








Mr. Joel F. Gemunder
August 29, 2001
Page 6


     negotiations with you and the Informed Parties at any time. Neither you nor
     the Company shall have rights or obligations of any kind whatsoever with
     respect to the Transaction by virtue of this letter agreement other than
     for the matters specifically agreed to herein. Without limiting the
     preceding sentences, nothing in this letter agreement requires either you
     or the Company to enter into a Transaction or to negotiate such Transaction
     for any specified period of time.

15.  You agree that no contract or agreement providing for a Transaction shall
     be deemed to exist between the parties and/or any of the parties'
     stockholders unless and until a detailed definitive written agreement
     providing for a Transaction (a "Transaction Agreement") has been executed
     and delivered by both parties, and each party hereby waives in advance, any
     claims (including, without limitation, claims for breach of contract) in
     connection with any possible Transaction unless and until the parties shall
     have entered into such definitive Transaction Agreement. You also agree
     that unless and until such definitive Transaction Agreement has been
     executed and delivered by both parties neither party has any legal
     obligation of any kind whatsoever with respect to any Transaction by virtue
     of this letter agreement or any other written or oral expression with
     respect to such Transaction except, in the case of this letter agreement,
     for the matters specifically agreed to herein. For purposes of this
     paragraph, the term "definitive Transaction Agreement" does not include an
     executed letter of intent or any other preliminary written agreement, nor
     does it include any written or oral acceptance of any offer or bid by any
     party.

16.  Each party agrees that because an award of money damages (whether pursuant
     to the foregoing sentence or otherwise) would be inadequate for any breach
     of this letter agreement, and any such breach would cause irreparable harm,
     in the event of any breach or threatened breach of this letter agreement,
     each party will also be entitled, without the requirement of posting a bond
     or other security, to equitable relief, including injunctive relief and
     specific performance. Such remedies will not be the exclusive remedies for
     any breach of this letter agreement but will be in addition to all other
     remedies available at law or equity.

17.  The agreements contained in this letter agreement shall be binding upon the
     successors of the parties hereto.

18.  This letter agreement contains the entire agreement between you and the
     Company concerning the Confidential Information, and this letter agreement
     and the obligations set forth in this letter agreement may be modified or
     waived only by a separate writing signed by the Company and you expressly
     modifying or waiving this letter agreement or such obligations.








Mr. Joel F. Gemunder

19.  Neither the failure nor the delay by any party in exercising any right,
     power or privilege under this letter agreement will operate as a waiver of
     such right, power or privilege, and no single or partial exercise of any
     such right power or privilege will preclude any other or further exercise
     of such right, power or privilege or the exercise of any other right, power
     or privilege.

20.  As used in this letter agreement, the term "person" means any individual,
     corporation (including any nonprofit corporation), general or limited
     partnership, limited liability company, joint venture, estate, trust,
     association, organization, labor union or other entity or governmental
     body.

21.  The invalidity or unenforceability of any provision of this letter
     agreement shall not affect the validity or enforceability of any other
     provisions of this letter agreement, which shall remain in full force and
     effect. If any of the covenants or provisions of this letter agreement are
     determined to be unenforceable by reason of its extent, duration, scope or
     otherwise, then the parties contemplate that the court making such
     determination shall reduce such extent, duration, scope or other provision
     and enforce them in their reduced form for all purposes contemplated by
     this letter agreement.

22.  All words used in this letter agreement will be construed to be of such
     gender or number as the circumstances require. Unless otherwise expressly
     provided, the word "including" does not limit the preceding words or terms.

23.  Any action or proceeding seeking to enforce any provision of, or based upon
     any right arising out of, this letter agreement may be brought against
     either of the parties in the courts of the Delaware and each of the parties
     consents to the jurisdiction of such courts (and of the appropriate
     appellate courts) in any such action or proceeding and waives any objection
     to venue laid therein. Process in any action or proceeding referred to in
     the preceding sentence may be served on any party anywhere in the world.

24.  This letter agreement will be governed by and construed in accordance with
     the laws of the state of Delaware applicable to contracts between residents
     of that state and executed in and to be performed in that state, without
     regard to conflicts of laws principles.

25.  This letter agreement may be executed in one or more counterparts, each of
     which will be deemed to be an original copy of this letter agreement, and
     all of which, when taken together, shall be deemed to constitute one and
     the same agreement. The exchange of copies of this letter agreement and of
     signature pages by facsimile transmission shall constitute effective
     execution and delivery of this letter agreement as to the parties and may
     be used in lieu of the








Mr. Joel F. Gemunder
August 29, 2001
Page 8


     original letter agreement for all purposes. Signature of the parties
     transmitted by facsimile shall be deemed to be their original signatures
     for any purpose whatsoever.

26.  The parties have participated jointly in the negotiation and drafting of
     this letter agreement. If an ambiguity or question of intent or
     interpretation arises, this letter agreement shall be construed as if
     drafted jointly by the parties and no presumption or burden of proof shall
     arise favoring or disfavoring any party by virtue of the authorship of any
     of the provisions of this letter agreement.

27.  Notwithstanding anything to the contrary that may be contained herein, this
     letter agreement shall terminate two years from the date of your acceptance
     hereof. If you are in agreement with the foregoing, please sign and return
     one copy of this letter agreement, which thereupon will constitute our
     agreement with respect to its subject matter.
