In addition, the Company proposes to grant to the Underwriters an option (the “Option”) to purchase up to an additional 843,750 shares (the “Option Shares” and, together with the Firm Shares, the “Shares”).

This is to confirm the agreement between the Company and the Underwriters concerning the offer, issuance and sale of the Shares.

1. Representations, Warranties and Agreements of the Company. The Company represents and warrants to, and agrees with, each Underwriter that:

(a) The Registration Statement on Form S-3 (File No. 333-103115), including a related prospectus, setting forth information with respect to the Company and the Shares has (i) been prepared by the Company in conformity in all material respects with the requirements of the Securities Act, (ii) been filed with the Commission under the Securities Act and (iii) become effective under the Securities Act. Copies of such Registration Statement and all amendments and exhibits thereto have been made available by the Company to you. The Company has included in such registration statement, as amended at the Effective Time, all information (other than Rule 430A Information) required by the Securities Act and the rules thereunder to be included in such registration statement and the related prospectus. The Company will next file

with the Commission the Prospectus in accordance with Rules 415 and 424(b). As filed, such Prospectus will contain all Rule 430A Information, together with all other such required information, and, except to the extent the Underwriters will agree in writing to a modification, will be in all substantial respects in the form furnished to you prior to the Execution Time, or, to the extent not completed at the Execution Time, shall contain only such additional information and other changes as the Company has advised you, prior to the Execution Time, will be included or made therein or such changes as are made after consulting with you or your counsel.

(b) The conditions for use of Form S-3, as set forth in the General Instructions thereto, have been satisfied or waived.

(c) The Registration Statement conforms, and the Prospectus and any further amendments or supplements to the Registration Statement or the Prospectus will, when they become effective or are filed with the Commission, as the case may be, conform in all material respects to the requirements of the Securities Act. The Registration Statement and any amendment thereto did not, and will not, as of the applicable Effective Date, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The Prospectus does not and will not, as of the date thereof and any applicable Delivery Date (as defined in Section 4(c)), contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, it being understood that the Company makes no representation or warranty as to information contained in or omitted from the Registration Statement or the Prospectus in reliance upon and in conformity with written information furnished to the Company by the Underwriters specifically for inclusion therein as provided in Section 8(e).

(d) The Incorporated Documents as amended or supplemented at the date hereof, when they were filed with the Commission, conformed in all material respects to the requirements of the Securities Act and the Exchange Act. None of the Incorporated Documents as amended or supplemented at the date hereof, when such documents were filed with the Commission, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Any further documents so filed and incorporated by reference in the Prospectus, when such documents are filed with Commission will conform in all material respects to the requirements of the Exchange Act and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(e) The Company has an authorized capitalization as of March 31, 2003 as set forth under the heading “Capitalization” in the Prospectus.

All of the issued and outstanding shares of capital stock or other equity interests of each of the Significant Subsidiaries owned by the Company

(directly or indirectly) are owned free and clear of any liens (other than those that could not reasonably be expected to have a material adverse affect on the business, condition (financial or other), results of operations, or properties of the Company and its subsidiaries, taken as a whole (a “Material Adverse Effect”)).

(j) None of the issuance, offer and sale of the Shares, the execution, delivery and performance of this Agreement by the Company or the consummation by the Company of the transactions contemplated hereby violate or will violate, conflict with or constitute a breach of

any of the terms or provisions of or a default under (or an event that with notice or the lapse of time, or both, would constitute a default), or require consent under, or result in the creation or imposition of a lien, charge or encumbrance on any property or assets of the Company or any Significant Subsidiary pursuant to, (i) the charter, bylaws or other constitutive documents of the Company or any Significant Subsidiary, (ii) any law, statute, rule or regulation applicable to the Company or any Subsidiary or their respective assets or properties or (iii) any judgment, order or decree of any domestic or foreign court or governmental agency or authority having jurisdiction over the Company or any Significant Subsidiary or their respective assets or properties, which, in the case of clauses (ii), and (iii), individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

(n) Except as set forth in the Prospectus, there is no action, suit or proceeding before or by any court, arbitrator or governmental agency, body or official, domestic or foreign, now pending or, to the knowledge of the Company, threatened or contemplated, to which the Company or any Significant Subsidiary is or may be a party or to which the business, assets or property of such person is or may be subject, that if determined adversely to the Company or any Significant Subsidiary, could, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or to materially and adversely affect the ability of the Company to perform its obligations under this Agreement.

securities authority or agency of any jurisdiction for additional information with respect to any of the Shares that has been received by the Company or its counsel prior to the date hereof has been, or will prior to the First Delivery Date be, complied with in all material respects.

(o) The Company and each Significant Subsidiary has (i) all licenses, certificates, permits, authorizations, approvals, franchises and other rights from, and has made all declarations and filings with, all applicable authorities, all self-regulatory authorities and all courts and other tribunals (each, an “Authorization”) necessary to engage in the business conducted by it in the manner described in the Prospectus, except where failure to have obtained such Authorizations or made such declarations and filings could not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect and (ii) no reason to believe that any governmental body or agency, domestic or foreign, is considering limiting, suspending or revoking any such Authorization, except where any such limitations, suspensions or revocations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. All such Authorizations are valid and in full force and effect and the Company and each Significant Subsidiary is in compliance in all material respects with the terms and conditions of all such Authorizations and with the rules and regulations of the regulatory authorities having jurisdiction with respect to such Authorizations, except for any invalidity, failure to be in full force and effect or noncompliance with any Authorization that could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(t) The Company, including its subsidiaries, has the requisite provider number or other authorization to bill the Medicare program (to the extent such entity participates in the Medicare program) and the respective Medicaid program in the state or states in which it operates, except where the failure to have such provider number or other authorization could not be reasonably expected to have a Material Adverse Effect.

(u) Neither the Company, nor to its knowledge, any of its affiliates (as defined in Regulation D of the Securities Act, an “Affiliate”), has taken, directly or indirectly, any action designed to cause or result in, or which has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of the Shares to facilitate the sale or resale of such Shares.

(o) Since the Execution Time there shall not have been any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, stockholders’ equity or results of operations of the Company on consolidated basis, otherwise than as set forth or contemplated in the Prospectus, the effect of which is, in the reasonable judgment of Lehman Brothers, so material and adverse as to make it impracticable or inadvisable to proceed with the offering or the delivery of the Shares being delivered on such Delivery Date on the terms and in the manner contemplated in the Prospectus.

(p) Subsequent to the execution and delivery of this Agreement (i) no downgrading shall have occurred in the corporate or issuer rating accorded the Company by any “nationally recognized statistical rating organization”, as that term is defined by the Commission for

purposes of Rule 436(g)(2) of the Securities Act and (ii) no such organization shall have publicly announced or notified the Company in writing that it has under surveillance or review, with possible negative implications, its corporate or issuer rating of the Company.

(q) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange or the Nasdaq National Market or trading in any securities of the Company on any exchange, shall have been suspended, the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on any such exchange or market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by Federal or state authorities, (iii) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States, or there shall have been a presidential declaration of a national emergency or a declaration of war by the United States, or (iv) there shall have occurred a material adverse change in general domestic or international economic, political or financial conditions, including, without limitation, as a result of terrorist activities, or the effect of international conditions on the financial markets in the United States shall be such, as to make it in the reasonable judgment of Lehman Brothers, impracticable or inadvisable to proceed with the public offering or delivery of the Shares being delivered on such Delivery Date on the terms and in the manner contemplated in the Prospectus.

(r) By the date of execution and delivery of this Agreement, the Company shall have furnished to the Representatives each of the letters required to be furnished under Section 7(z) of the underwriting agreement of even date herewith among the Company, Omnicare Capital Trust I and the underwriters named therein to such underwriters in connection with the offer and sale of $250,000,000 aggregate liquidation amount of Trust Preferred Income Equity Redeemable Securities.

The documents required to be delivered by this Section 7 will be delivered at the office of counsel for the Company (or at such other location agreed to between the Company and the Underwriters) on the Delivery Date.

8. Conditions of the Obligations of the Company. The obligations of the Company hereunder shall be subject to the consummation of the Company’s proposed public offering of 6.125% Senior Subordinated Notes due 2013 aggregating at least $250 million of gross proceeds (the “Notes Offering”) and the completion of the Company’s proposed new credit facility comprised of a $250 million term loan and a $500 million revolving loan, in all cases as described in the Prospectus. If such condition shall not have been fulfilled, this Agreement may be terminated by the Company upon notice thereof to Lehman Brothers. Any such termination shall be without liability of any party to any other party except as otherwise provided in Sections 6, 9 and 12 hereof, provided, however that if the Notes Offering shall have been terminated by reason of default of one or more underwriters of such offering, the Company shall not be obligated to reimburse the expenses of any defaulting underwriter, and provided, further, that the Company shall have no liability under Section 12 hereto in the event that the underwriting agreement in connection with the Notes Offering shall have been terminated as a result of any failure to meet condition 7(t) of such agreement.

9. Indemnification and Contribution.

(a) The Company shall indemnify and hold harmless each Underwriter, its directors, officers and employees and each person, if any, who controls any Underwriter within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of the Shares), to which that Underwriter, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The Company shall reimburse each Underwriter and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any such amendment or supplement, in reliance upon and in conformity with the written information concerning that Underwriter furnished to the Company through the Representatives by or on behalf of any Underwriter concerning that Underwriter specifically for inclusion therein which information consists solely of the information set forth in Section 9(e); and provided, further, that the Company shall not be liable to indemnify any Underwriter or any person who controls such Underwriter on account of any such loss, liability, claim, damage or expense arising out of any such defect or alleged defect in any Preliminary Prospectus or Prospectus if a copy of the Prospectus (exclusive of the Incorporated Documents), as amended or supplemented, shall not have been given or sent by such Underwriter with or prior to the written confirmation of the sale involved to the extent that the Prospectus, as amended or supplemented, would have cured such defect or alleged defect and sufficient quantities of the Prospectus, as amended or supplemented, were made available to such Underwriter to allow it to deliver such Prospectus on a timely basis. The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Underwriter or to any director, officer, employee or controlling person of that Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless, the Company, its officers and employees, each of its directors, and each person, if any, who controls the Company within the meaning of the Securities Act from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment

or supplement thereto, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment or supplement thereto, any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with the written information furnished to the Company through the Representatives by or on behalf of that Underwriter specifically for inclusion therein and described in Section 9(e). The Underwriters, severally and not jointly, shall reimburse the Company and any such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Company or any such director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which any Underwriter may otherwise have to the Company or any such director, officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 9 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 9 except to the extent it has been materially prejudiced by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 9. If any such claim or action shall be brought against an indemnified party, and it has notified the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 9 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Underwriters shall have the right to employ separate counsel to represent jointly the Underwriters and their respective officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Company under this Section 9 if, in the reasonable judgment of counsel to such Underwriters, it is advisable for such Underwriters, officers, employees and controlling persons to be jointly represented by separate counsel, due to the availability of one or more legal defenses to them which are different from or additional to those available to the indemnifying party, and in that event the reasonable fees and expenses of such separate counsel shall be paid by the Company; provided further, that the Company shall not be liable for the fees and expenses of more than one separate firm of attorneys (in addition to one local counsel in each relevant jurisdiction) at any time for all such indemnified parties. No indemnifying party shall, (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld) settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified

parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fault, culpability or failure to act by or on behalf of any indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but, for the avoidance of doubt, if settled with its written consent or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 9 shall for any reason be unavailable or insufficient to hold harmless an indemnified party under Section 9(a) or 9(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, other than to the extent that such indemnification is unavailable or insufficient due to a failure to provide prompt notice in accordance with Section 9(c), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares, or (ii) if the allocation provided by clause 9(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 9(d)(i) but also the relative fault of the Company on the one hand and the Underwriters on the other with respect to the statements or omissions or alleged statements or alleged omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Shares purchased under this Agreement (before deducting expenses) received by the Company on the one hand, and the total underwriting discounts and commissions realized or received by the Underwriters with respect to the Shares purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Shares under this Agreement, in each case, as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if the amount of contributions pursuant to this Section 9(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation, which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 9(d) shall be deemed to include, for purposes of this Section 9(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public was offered to the public exceeds the amount of any damages which such Underwriter has otherwise paid or

become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 9(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and the Company acknowledges that the statements with respect to the offering of the Shares by the Underwriters set forth in the last paragraph on the cover page and the first paragraph under the caption “Underwriting—Commissions and Expenses,” the first paragraph and the second sentence of the second paragraph under the caption “Underwriting—Price Stabilization and Short Positions,” the third sentence of the first paragraph and the third sentence of the second paragraph under the caption “Underwriting—Other Relationships,” the first paragraph under the caption “Underwriting—Electronic Distribution” and the last sentence under the caption “Notice to Canadian Residents—Relationship with Affiliates of Certain Underwriters” in the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company through the Representatives by or on behalf of the Underwriters specifically for inclusion in the Prospectus, and the Underwriters severally confirm that such statements are accurate and complete.

10. Defaulting Underwriters.

(a) If, on any Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the number of Shares which the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of Shares set opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the aggregate number of Shares set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Shares on such Delivery Date if the total number of Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 10% of the total aggregate number of the Shares to be purchased on such Delivery Date. If the foregoing maximum is exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to Lehman Brothers who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, the total number of Shares to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to Lehman Brothers do not elect to purchase on such Delivery Date the aggregate number of Shares which the defaulting Underwriters agreed but failed to purchase, this Agreement (or with respect to the Option Delivery Date, the obligation of the Underwriters to purchase the Option Shares) shall terminate without liability on the part of any non-defaulting Underwriter and the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 12. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 10(a), purchases Shares which a defaulting Underwriter agreed but failed to purchase.

(b) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default. If other Underwriters are obligated or agree to purchase the Shares of a defaulting or withdrawing Underwriter, either Lehman Brothers or the Company may postpone the Delivery Date for up to five full Business Days in order to effect any changes that, in the opinion of counsel to the Company or counsel to the Underwriters, may be necessary in the Prospectus or in any other document or arrangement.

11. Termination. The obligations of the Underwriters hereunder may be terminated by the Underwriters by notice given to and received by the Company prior to delivery of and payment for the Shares if, prior to that time, any of the events described in Sections 7(o), 7(p) or 7(q) shall have occurred or if the Underwriters shall decline to purchase the Shares for any reason permitted under this Agreement.

12. Reimbursement of Underwriters’ Expenses. If (a) the Company shall fail to tender the Shares for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Company (including, without limitation, with respect to the transactions) is not fulfilled (other than as a result of the condition described in Section 7(q)) or (b) the Underwriters shall decline to purchase the Shares for any reason permitted under this Agreement (including the termination of this Agreement pursuant to Section 11) (other than as a result of the condition described in Section 7(q)), the Company shall reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Shares (except as otherwise provided in Section 8 hereof), and upon demand the Company shall pay the full amount thereof to the Underwriters. Upon such payment the Company will be absolved from any further liability hereunder, except as provided in Sections 6 and 9 hereof. If this Agreement is terminated pursuant to Section 10 by reason of the default of one or more Underwriters, the Company shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

13. Notices, etc. Notices given pursuant to any provision of this Agreement shall be given in writing and shall be addressed as follows:

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The Company shall be entitled to act and rely upon any request, consent, notice or agreement given or made on behalf of the Underwriters by Lehman Brothers or the Representatives on behalf of the Underwriters.

16. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

To our knowledge, no consents or waivers from any other person or entity are required for the execution, delivery and performance by the Company of the Underwriting Agreement or the consummation by the Company of any of the transactions contemplated thereby, other than (X) such consents and waivers as have been obtained and as are in full force and effect and (Y) such consents and waivers that, if not obtained, could not reasonably be expected to have a Material Adverse Effect.

(viii) The Company is not an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(ix) The statements under the caption “Description of Common Stock” in the Prospectus, insofar as such statements constitute a summary of applicable law or of legal matters set forth in contracts, agreements or other legal documents, fairly present in all material respects such applicable law or such contracts, agreements or other legal documents.

(x) The statements set forth in the Prospectus under the caption “Material United States Federal Income Tax Consequences for Non-U.S. Holders,” insofar as they purport to constitute summaries of matters of United States federal income tax law and regulations or legal conclusions with respect thereto, constitute accurate summaries of the matters described therein in all material respects.

Except as set forth in paragraphs (ix) and (x) above, we have not undertaken to determine independently and, therefore, do not pass upon or assume any responsibility for, explicitly or implicitly, the accuracy, completeness or fairness of the statements contained in the Prospectus. In addition, we have not participated in the preparation of the documents incorporated by reference in the Prospectus. We have, however, participated in conferences with your representatives and with representatives of the Company, with the Company’s counsel and with the Company’s independent accountants in the course of the preparation of the Prospectus in which such statements were generally reviewed and discussed. Based upon and subject to the foregoing (and relying as to materiality as to factual matters upon information furnished and assessments made by officers and other representatives of the Company and its subsidiaries), nothing has come to our attention that has caused us to believe that the Registration Statement, as of the Effective Time, or the Prospectus, on the date thereof and on the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (except as to the financial statements and the notes thereto and the schedules and other financial and accounting data and exhibits included or incorporated by reference therein or omitted therefrom, as to all of which we express no view).

EXHIBIT C

Form of Opinion of General Counsel of Omnicare, Inc.

The opinion of Peter Laterza, General Counsel for the Company (capitalized terms not otherwise defined herein shall have the meanings provided in the Underwriting Agreement, to which this is an Exhibit), delivered pursuant to Section 7(g) of the Underwriting Agreement:

(i) The Company and each of its Significant Subsidiaries which are incorporated in the United States has been duly incorporated and is validly existing as a corporation in good standing under the laws of its respective jurisdiction of incorporation, has all requisite corporate power and authority to own, lease and operate its properties and to conduct its business in all material respects as it is currently being conducted and as described in the Prospectus, and is duly qualified and in good standing as a foreign corporation authorized to do business in each jurisdiction in which the ownership, leasing and operation of its property and the conduct of its business requires such qualification (except where the failure to be so qualified and in good standing could not reasonably be expected to have a Material Adverse Effect).

(ii) The entities listed on Schedule 2 hereto are the only Significant Subsidiaries, direct or indirect, of the Company. Except as otherwise set forth in the Prospectus, the Company owns, directly or indirectly through other subsidiaries, the percentage indicated on Schedule 2 of the outstanding capital stock or other securities evidencing equity ownership of such Significant Subsidiaries, free and clear of any security interest and, to the knowledge of such counsel, any claim, lien, limitation on voting rights or encumbrance. All of such securities have been duly authorized, validly issued, are fully paid and nonassessable and were not issued in violation of any preemptive or similar rights. To my knowledge after due inquiry, there are no outstanding subscriptions, rights, warrants, calls, commitments of sale or options to acquire, or instruments convertible into or exchangeable for, any such shares of capital stock or other equity interest of such subsidiaries owned by the Company.

(iii) The Company has all requisite corporate power and authority to execute, deliver and perform its obligations under the Underwriting Agreement and to consummate the transactions contemplated thereby, including, without limitation, the corporate power and authority to issue, sell and deliver the Shares as provided in the Underwriting Agreement.

(iv) Except as set forth in the Prospectus or as could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or to interfere with or adversely affect the issuance of the Shares or the consummation of the transactions contemplated by the Underwriting Agreement, there is (A) no action, suit or proceeding before or by any court, arbitrator or governmental agency, body or official, domestic or foreign, now pending or, to the knowledge of such counsel, threatened or contemplated, to which the Company or any Significant Subsidiary is or may be a party or to which the business, assets or property of such person is or may be subject, (B) no statute, rule,

C-1

regulation or order relating to or affecting the Company or any Significant Subsidiary that has been enacted, adopted or issued by any governmental body or agency or (C) no injunction, restraining order or order of any nature by a federal or state court or foreign court of competent jurisdiction to which the Company or any Significant Subsidiary is or may be subject.

(v) To my knowledge, neither the Company nor any Significant Subsidiary is (A) in violation of its charter, bylaws or other constitutive documents, (B) in default (or, with notice or lapse of time or both, would be in default) in the performance or observance of any obligation, agreement, covenant or condition contained in any Agreement or Instrument or (C) in violation of any law, statute, rule, regulation, judgment, order or decree of any domestic or foreign court with jurisdiction over any of them or any of their assets or properties or other governmental or regulatory authority, agency or other body, that, in the case of clauses (A), (B) and (C) individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

(vi) To my knowledge, the Company and each Significant Subsidiary has all Authorizations necessary to engage in the business conducted by it, except where failure to hold such Authorizations could not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect. I have no reason to believe that any governmental body or agency, domestic or foreign, is considering limiting, suspending or revoking any such Authorization, except where any such limitations, suspensions or revocations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. To my knowledge, all such Authorizations are valid and in full force and effect and the Company and each Significant Subsidiary is in compliance in all material respects with the terms and conditions of all such Authorizations and with the rules and regulations of the regulatory authorities having jurisdiction with respect to such Authorizations, has fulfilled and performed all of its material obligations with respect to such Authorizations and no event has occurred which allows, or after notice or lapse of time would allow, revocation or termination thereof, except for any invalidity, failure to be in full force and effect or noncompliance with, or revocation or termination of, any Authorization that could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(vii) The execution and delivery by the Company of the Underwriting Agreement, the issuance and sale of the Shares and the compliance by the Company with all of the provisions of the Underwriting Agreement will not violate or constitute a breach of any of the terms or provisions of, or a default under (or an event that with notice or the lapse of time, or both, would constitute a default), or require consent under, or result in the imposition of a lien or encumbrance on any properties of the Company or any of its Significant Subsidiaries which are incorporated in the United States, or an acceleration of indebtedness pursuant to, (A) the charter or bylaws of the Company or any of its Significant Subsidiaries which are incorporated in the United States, (B) any bond, debenture, note, indenture, mortgage, deed of trust or other agreement or instrument known to me to which the Company or any of its Significant Subsidiaries which are incorporated in the United States is a party or by which any of them or their property is or may be bound, (C) any U.S. federal or New York statute, rule or regulation reasonably

C-2

recognized by me as applicable to transactions of this kind, or (D) any judgment, order or decree known to me of any U.S. federal or New York court or governmental agency or authority having jurisdiction over the Company, any of its Significant Subsidiaries which are incorporated in the United States or their assets or properties, except for any such violations, breaches or defaults which would not reasonably be expected to have a Material Adverse Effect and except for such consents as may have been obtained by the Company or waived or such consents or filings as may be required or such as may be required under state or foreign securities or Blue Sky laws and regulations or such as may be required by the NASD.

(viii) No consents or waivers from any other person are required for the execution and delivery by the Company of the Underwriting Agreement, the issuance and sale of the Shares by the Company and the compliance by the Company with all of the provisions of the Underwriting Agreement, other than such consents and waivers as (A) would not reasonably be expected to have a Material Adverse Effect, (B) would not prohibit or adversely affect the issuance of the Shares, or (C) have been obtained or waived.

(ix) Each Incorporated Document (except for the financial statements and the notes thereto and the schedules and other financial, statistical and accounting data and exhibits included or incorporated by reference therein or omitted therefrom, as to all of which I express no opinion) appeared on its face to comply in all material respects as to form with the requirements of the Exchange Act and the rules and regulations of the Commission thereunder when filed with the Commission.

In addition, I have participated in conferences with other officers and other representatives of the Company, representatives of PricewaterhouseCoopers, the Underwriters and their counsel in connection with the preparation of the Registration Statement and the Prospectus at which conferences the contents of the Registration Statement and the Prospectus were discussed, reviewed and revised. Except as indicated above, I have not independently verified and am not passing upon, and do not assume responsibility for, the accuracy, completeness or fairness of the information contained in the Prospectus. Based upon the participation and discussions described above, however, no facts have come to my attention that cause me to believe that the Registration Statement, at the Effective Time, and the Prospectus, at the date thereof and on the applicable Delivery Date and the date hereof, contained or contains an untrue statement of material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that I have not been requested to and do not express any view as to the financial statements, notes and schedules or any other financial, statistical or accounting data included or incorporated by reference in or omitted from the Registration Statement and the Prospectus).
