          4.6.7 Right to Change Payment Terms. Without limiting MHS's rights
               under this Agreement or applicable law, which rights are hereby
               expressly reserved, MHS reserves the right to change a payment
               term (including imposing the requirement of cash payment upon

               MHS will validate with the supplier the reason of the shortage
               and expected resolution. The reasons for MUS may include

                    without notice

               o    Products supplied through alternate source or product
                    substitution delivered by the following day

          that have satisfied its indemnification, insurance and other corporate
          requirements. Products will be supplied at Omnicare's negotiated
          contract price plus MHS' applicable markup or discount as described in
          the Cost of Goods section above.

          after the applicable bid file data is furnished to MHS by Omnicare's
          group purchasing organization and confirmed by the vendor.

     7.4  An Omnicare Facility's eligibility for participation under a vendor
          contract must be authorized by the vendor, Omnicare and/or Omnicare's
          group purchasing organization before the contract is loaded by MHS for
          such Omnicare Facility. Each Omnicare Facility and Omnicare shall be
          liable for unpaid chargebacks resulting from eligibility issues.
          Omnicare is also responsible for denied chargebacks do to the lack of
          proper notification of group membership.

          creditors, files a petition in bankruptcy, is adjudicated insolvent or
          bankrupt, or if a receiver or trustee is appointed with respect to a
          substantial part of the vendor's property or a proceeding is commenced
          against it which will substantially impair its ability to pay on
          chargebacks; or (ii) otherwise defaults in the payment of chargebacks
          to MHS, each Omnicare Facility shall be invoiced and become liable for

          submit all claims for such credits and any other documentation related
          to the pricing discrepancy [ ** ]. With the data received from
          Omnicare, MHS will [ ** ]. All discrepancies between Omnicare's
          information and the MHS file information will be [ ** ].

     7.7  Should pricing information from Omnicare and the MHS contract pricing
          file conflict, the documentation from the manufacturer shall take
          precedence. Omnicare has the right to directly contact the
          manufacturer for verification of contract pricing.

     7.8  As a result of MHS research, if credit is required to correct a
          contract pricing error, MHS will complete this process within fifteen
          (15) days of verification of the correct price.


                                       13






     7.9  MHS will credit Omnicare for all price errors that are validated
          during this fifteen (15) day period; in the event that MHS is unable
          to complete its research within the fifteen (15) day period, MHS will
          reimburse Omnicare for the reported price discrepancies. Such credit
          will be offset by researched and reconciled addbills from denied
          chargebacks by manufacturers, and approved for payment according to
          the then current payment terms if the dollar amount of addbills exceed
          credit and rebills.

     7.10 Omnicare shall be responsible for notifying vendors and MHS of any
          change in membership. Each Omnicare Facility's membership must be
          authorized by the vendor and the group purchasing organization before
          contracts are loaded to the account. (Notification should be sent to
          the National Processing Center, McKesson Health Systems, 1220 Senlac,
          Carrollton, TX 75006.) The membership notification process can be set

                                       18






          DISCOUNT IS NOT KNOWN AT THE TIME OF A SALE, FULLY AND ACCURATELY
          REPORT THE EXISTENCE OF A DISCOUNT PROGRAM ON THE INVOICE, STATEMENT,
          OR REPORTS SUBMITTED TO OMNICARE OR OMNICARE FACILITIES AND, WHEN THE
          VALUE OF THE DISCOUNT BECOMES KNOWN, PROVIDE OMNICARE AND OMNICARE
          FACILITIES WITH DOCUMENTATION OF THE CALCULATION IDENTIFYING THE
          SPECIFIC GOODS OR SERVICES PURCHASED TO WHICH THE DISCOUNT WILL BE
          APPLIED TO OMNICARE AS BUYER. WHERE A DISCOUNT OR OTHER REDUCTION IN
          PRICE IS APPLICABLE, THE PARTIES ALSO INTEND TO COMPLY WITH THE
          REQUIREMENTS OF 42 U.S.C. Section 1320a-7b (b) (3) (A) AND THE "SAFE
          HARBOR" REGULATIONS REGARDING DISCOUNTS OR OTHER REDUCTIONS IN PRICE
          SET FORTH AT 42 C.F.R. Section 1001.952(h). IN THIS REGARD, THE
          PARTIES ACKNOWLEDGE THAT MHS WILL SATISFY ANY AND ALL REQUIREMENTS
          IMPOSED ON SELLERS BY THE SAFE HARBOR AND OMNICARE AND/OR OMNICARE
          FACILITIES WILL SATISFY ANY AN ALL REQUIREMENTS IMPOSED ON BUYERS.
          THUS, OMNICARE AND/OR OMNICARE FACILITIES WILL ACCURATELY REPORT,
          UNDER ANY STATE OR FEDERAL PROGRAM WHICH PROVIDES COST OR CHARGE BASED
          REIMBURSEMENT FOR THE PRODUCTS AND SERVICES COVERED BY THIS AGREEMENT,
          THE NET COST ACTUALLY PAID BY A OMNICARE FACILITY. IN THE EVENT EITHER
          PARTY DETERMINES THAT THIS DISCOUNT PROGRAM MAY NOT COMPLY WITH SUCH
          STATUTES, THE PARTIES AGREE TO WORK TOGETHER TO ESTABLISH A DISCOUNT
          STRUCTURE THAT MEETS THE REQUIREMENTS OF SUCH STATUTES. TO THE EXTENT
          ANY APPLICABLE LAW, REGULATION, OR GOVERNMENTAL OR JUDICIAL ORDER
          REQUIRES DISCLOSURE TO ANY GOVERNMENTAL AGENCY OF ANY INFORMATION
          REGARDING MHS'S SALE OF PRODUCTS TO OMNICARE UNDER THIS AGREEMENT MHS
          WILL USE REASONABLE BEST EFFORTS TO PROVIDE OMNICARE PRIOR NOTICE
          BEFORE MAKING SUCH DISCLOSURE.

     13.15 Governing Law. This Agreement and all rights and liabilities of the
          parties shall be subject to and governed by the substantive law (and
          not the choice of law rules) of the State of New York.

     13.16 Entire Agreement. This Agreement embodies the entire agreement
          between the parties with regard to the subject matter hereof and
          supersedes all prior agreements, understandings and representations
          with the exception of any promissory note, security agreement or other
          credit or financial related document(s) executed by Omnicare or
          between Omnicare and McKesson. This Agreement may not be modified,
          supplemented or extended except by a writing signed by both parties.

          participating.
