Morgan Securities Inc., Lehman Brothers Inc. and CIBC World Markets Corp., the other underwriters named in Schedule 1 hereto and any additional underwriters pursuant to Section 10(a) herein (individually, each an “Underwriter” and collectively, the “Underwriters”), for whom you are acting as representatives (the “Representatives”), $850,000,000 aggregate principal amount of its 3.25% Convertible Senior Debentures due 2035 (the “Firm Debentures”), to be issued pursuant to the Indenture (the “Indenture”) to be entered into among the Company, the Guarantor (as defined below) and SunTrust Bank, as indenture trustee (in such capacity, the “Indenture Trustee”). In addition, the Company proposes to grant the Underwriters an option (the “Option”) to purchase up to an additional $127,500,000 aggregate principal amount of Debentures (the “Option Debentures” and together with the Firm Debentures, the “Debentures”). The Company’s obligations under the Debentures and the Indenture will be unconditionally guaranteed (the “Guarantee”) on an unsecured senior subordinated basis by Omnicare Purchasing Company L.P., as guarantor (the “Guarantor” and, together with the Company, the “Issuers”). The Debentures are convertible into shares of common stock, par value $1.00 per share (“Common Stock”) of the Company at the conversion price set forth in the Indenture.

This is to confirm the agreement among the Company, the Guarantor and the Underwriters concerning the offer, issuance and sale of the Debentures.

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 Applicable Time, or, to the extent not completed at the Applicable Time, shall contain only such additional information and other changes as the Company has advised you, prior to the Applicable Time, will be included or made therein or such changes as are made after consulting with you or your counsel.

(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.

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 Concurrent Offerings shall have been terminated by reason of default of one or more underwriters of such Concurrent Offerings, 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 either of the underwriting agreements shall have been terminated as a result of any failure to meet condition 7(q), in the case of the Common Stock Offering , or 7(r), in the case of the Bond Offering, of such agreements

9. Indemnification and Contribution.

(a) The Company and the Guarantor jointly and severally 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 Debentures), 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 (A) in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto or (C) any Permitted Issuer Information, or, (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any Permitted Issuer Information, 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 and the Guarantor agree jointly and severally to 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 Issuers 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, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Permitted Issuer Information, 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 Issuers 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 or the Guarantor 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, the Guarantor, their respective officers and employees, each of their directors, and each person, if any, who controls the Company or any of the Guarantor 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, the Guarantor 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, the Prospectus, any Issuer Free Writing 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, any Issuer Free Writing 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, the Guarantor and any such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Company, the Guarantor 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, the Guarantor 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 or the Guarantor 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 Issuers; provided further, that the Issuers 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 Debentures, 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 Debentures 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 Debentures purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Debentures 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 Debentures 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 Debentures by the Underwriters set forth in the last paragraph on the cover page and the second paragraph under the caption “Underwriting—Commissions and Expenses,” the second paragraph under “Underwriting—Lock-up Agreements,” the first paragraph and the third sentence of the second paragraph under the caption “Underwriting—Stabilization, Short Positions and Penalty Bids,” the second sentence of the first paragraph and the second, third and fourth sentences of the second paragraph under the caption “Underwriting—Other Relationships,” the section entitled “Underwriting—Discretionary Sales,” the second sentence of the section entitled “Underwriting—Liquidity of the Trading Market” and the first paragraph under the caption “Underwriting—Electronic Distribution” 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 any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, and the Underwriters severally confirm that such statements are accurate and complete.

(f) Without limitation of and in addition to its obligations under the other paragraphs of this Section 9, the Company agrees to indemnify and hold harmless Credit Suisse First Boston LLC (in the capacity described in this paragraph, the “Independent Underwriter”), its directors, officers and employees and each person who controls Independent Underwriter within the meaning of Section 15 of the Securities Act from and against any and all 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 Debentures) to which the Independent 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, the Independent Underwriter’s acting as a “qualified independent underwriter” (within the meaning of NASD Conduct Rule 2720) in connection with the offering contemplated by this Agreement, and agrees to reimburse each such indemnified party promptly upon demand for any legal or other expenses reasonably incurred by them in connection with investigating or defending or preparing to defend any such loss, claim, damage, liability or action; provided, however, that the Company shall not be liable in any such case to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from the gross negligence or willful misconduct of the Independent Underwriter. The relative benefits received by the Independent Underwriter with respect to the offering contemplated by this Agreement shall, for purposes of Section 9(d), be deemed to be equal to the compensation received by the Independent Underwriter for acting in such capacity. In addition, notwithstanding the provisions of Section 9(d), the Independent Underwriter shall not be required to contribute any amount in excess of the compensation received by the Independent Underwriter for acting in such capacity.

10. Defaulting Underwriters.

(a) If, on the 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 Debentures which the defaulting Underwriter agreed but failed to purchase on the Delivery Date in the respective proportions which the aggregate amount of Debentures set opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the aggregate amount of Debentures 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 Debentures on the Delivery Date if the total amount of Debentures which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 10% of the total aggregate amount of the Debentures to be purchased on the 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 amount of Debentures to be purchased on the Delivery Date. If the remaining Underwriters or other underwriters satisfactory to Lehman Brothers do not elect to purchase on the Delivery Date the aggregate amount of Debentures which the defaulting Underwriters agreed but failed to purchase, this Agreement 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 Debentures 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 Debentures 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 Debentures 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 Debentures for any reason permitted under this Agreement.

12. Reimbursement of Underwriters’ Expenses. If (a) the Company shall fail to tender the Debentures 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 or the Guarantor (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 Debentures 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 and the Guarantor agree jointly and severally to 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 Debentures (except as otherwise provided in Section 8 hereof), and upon demand the Issuers shall pay the full amount thereof to the Underwriters. Upon such payment the Issuers 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 Issuers shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.
