PRIME VENDOR AGREEMENT

This Prime Vendor Agreement (“Agreement”) is made as of May 1, 2006 (“Effective Date”) by AmerisourceBergen Drug Corporation, a Delaware corporation (“ABDC”), and NMHCRx Mail Order, Inc., dba NMHC Mail, a Delaware corporation (“Customer”).

A. ABDC is a national distributor of pharmaceutical and other products, including prescription (“Rx”) and over-the-counter (“OTC”) Pharmaceuticals, nutritional, health and beauty care (“HBC”) and home health care (“DME”) products (“Product” or “Products”), and services (“Services”);

B. Customer owns and operates one or more alternate care pharmacies (“Facilities”); and

C. The parties intend by this Agreement to set forth their obligations to each other for an arrangement under which ABDC will provide Products and Services to Customer (“Program”).

NOW THEREFORE, the parties agree as follows:

ABDC will be the Primary Vendor of all requirements of Customer’s Facilities for Products. Customer will pay, within terms, Product costs and Program fees pursuant to payment terms in Exhibit “1” (“Pricing/Payment Terms”). “Primary Vendor” means Customer purchases from ABDC no less than 90% of all prescription pharmaceutical Products it purchases, as verified quarterly, and meets minimum periodic purchase levels in Paragraph 3(A) of the Pricing/Payment Terms. Orders for Products will be electronically transmitted (including Schedule II controlled substances when allowed) and will describe Products that ABDC will provide to Customer, the quantity and designated delivery location. All payment plans (except pre-pay) must be by electronic funds transfer (EFT).

Customer must elect to participate in ABDC’s preferred generic formulary program (“Preferred Rx Options” or “PRxO Generics”) pursuant to requirements as amended from time to time by ABDC. Customer will purchase no less than 3% of its total purchases from ABDC’s PRxO Generics program. Customer authorizes ABDC as its sole agent to develop and implement a generic pharmaceutical Product list for the Term. Customer will purchase from ABDC each calendar quarter no less than the minimum Net Purchase volume of generic pharmaceutical Products as set forth in the Pricing/Payment Terms.

ABDC will deliver Products to each Facility five days a week (Monday-Friday), once a day except holidays and warehouse physical inventory days. Additionally, Customer will be entitled to three emergency deliveries per calendar quarter per pharmacy location at no additional charge. Customer may be charged for each additional emergency order. Facility means each of Customer’s alternate care pharmacies, together with any other facilities Customer acquires, is affiliated with or operates during the Term in the United States. Newly acquired facilities with existing agreements with other distributors will become Facilities under this Agreement upon the earlier of expiration of such existing agreement or the date Customer may terminate such agreement, with or without cause, without breaching it or paying a material termination penalty; provided, however, service to Facilities outside ABDC’s normal service area (which does not include Alaska, Hawaii or U.S. territories) may be subject to a delivery surcharge.

Customer will only return Products to ABDC in accordance with ABDC’s standard policy for returned Products (“Returned Goods Policy”), as amended from time to time by ABDC. If Customer returns more than 3% of its OTC Net Purchases, or 3% of its pharmaceutical Net Purchases in any quarter, Customer may be assessed an additional restocking fee over any standard stocking fee in the Returned Goods Policy or ABDC may adjust the Price of Goods or both. Customer will return only Product purchased from ABDC for which Customer has submitted the invoice number and date of purchase. ABDC may reject returns not accompanied by the invoice number and date of purchase or that exceed in amount either the 3% return limit or the amount on the referenced invoice number. ABDC reserves the right to refuse all future returns from Customer in the event that Customer submits any counterfeit Product for return.

Services are listed in Exhibit “2” . Terms, conditions and other provisions are set forth in Exhibit “3” (“Provisions”). ABDC may, from time to time, develop policies and procedures relative to new or existing Services offered to customers, on an interim or as-needed basis. If ABDC develops such policies or procedures or changes current ones, ABDC will notify Customer in writing at least thirty (30) days before such changes are effective. If Customer is materially adversely affected by such policy or procedure, Customer may terminate this Agreement upon thirty (30) days written notice to ABDC.

Subject to Paragraph 5 of the Provisions, the Term will be from the Effective Date until April 30, 2010 . The Term will, thereafter, be extended on a month-to-month basis until either party gives at least ninety (90) days prior written notice to the other of its intention not to extend this Agreement.

To the extent required by 42 U.S.C. §1395x(v)(1), until four (4) years after termination of this Agreement, ABDC will make available upon written request to the Secretary of the U.S. Department of Health & Human Services (“HHS”), the Comptroller General, or their authorized representatives, a copy of this Agreement and all records required to certify the nature and extent of costs of Products and Services provided by ABDC under this Agreement. ABDC will ensure, to the extent it carries out its duties through a subcontract with a value or cost of $10,000 or more in a twelve (12) month period with a related organization, such subcontract will contain similar provisions. Notwithstanding the foregoing, ABDC will have no obligation to make public documents subject to attorney-client privilege.

Notices must be in writing and sent certified mail, prepaid, return receipt requested, or sent by facsimile to the address or facsimile number below. Parties may change this information by written notice to the other party.

Except as otherwise provided, payments are due within ten (10) days from ABDC’s invoice date. Pricing does not reflect any administrative or other fee to a group purchasing organization or buying group (“GPO”). If Customer contracts with a GPO, Customer will pay any such fees to the applicable GPO. In any event, ABDC will not pay a GPO fee unless and until a group designation form signed by Customer is filed with ABDC. Customer will pay any increase in GPO administrative fees during the Term of this Agreement.
