1 EXHIBIT 10.8 AMENDMENT Dated as of September 28, 1998 to RECEIVABLES PURCHASE AGREEMENT Dated as of August 28, 1997 THIS AMENDMENT (this "Amendment") dated as of September 28, 1998 is entered into by and between NMC FUNDING CORPORATION, a Delaware corporation, as Purchaser (the "Purchaser") and NATIONAL MEDICAL CARE, INC., a Delaware corporation, as Seller (the "Seller"). PRELIMINARY STATEMENT A. The Purchaser and the Seller are parties to that certain Receivables Purchase Agreement dated as of August 28, 1997 (as amended or otherwise modified prior to the date hereof, the "RPA"). Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to them in the RPA. B. The Purchaser and the Seller have agreed to amend the RPA on the terms and conditions hereinafter set forth. NOW, THEREFORE, in consideration of the premises set forth above, and other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows: SECTION 1. Amendments to the RPA. Subject to the satisfaction of the conditions precedent set forth in Section 2 below, the RPA is amended as follows: 1.1. The following new definitions are added to Section 1.1 of the RPA in appropriate alphabetical order: "Receivable Systems" has the meaning specified in Section 3.1(z). "Year 2000 Compliant" has the meaning specified in Section 3.1(z). 1.2. Section 3.1 of the RPA is amended to add, immediately after paragraph (y), the following new paragraph (z): 2 "(z) Year 2000 Compliance. The Seller has (i) initiated a review and assessment of all areas within its and each of its Subsidiaries' business and operations (including those affected by suppliers, vendors and customers) that could be adversely affected by the 'Year 2000 Problem' (that is, the risk that computer applications used by the Seller or any of its Subsidiaries (or suppliers, vendors and customers) may be unable to recognize and perform properly date-sensitive functions involving certain dates prior to and any date after December 31, 1999), (ii) initiated the development of a plan and timeline for addressing the Year 2000 Problem on a timely basis, and (iii) to date, implemented that plan in accordance with that timetable. The Seller believes that all computer applications (including those of its suppliers, vendors and customers) that are material to its or any of its Subsidiaries' business and operations are reasonably expected on a timely basis to be able to perform properly date-sensitive functions for all dates before and after January 1, 2000 (that is, be 'Year 2000 Compliant'), except to the extent that a failure to do so could not reasonably be expected (a) to have a Material Adverse Effect on the Seller or on the transaction documented under this Agreement, or (b) to result in a Termination Event. The Seller (i) has initiated a review and assessment of all computer applications (including, but not limited to those of the Seller, any Transferring Affiliate and any of their respective suppliers, vendors, customers or third party servicers), which are related to or involved in the origination, collection, management or servicing of the Receivables (the 'Receivable Systems') and (ii) believes that such Receivable Systems are Year 2000 Compliant or will be Year 2000 Compliant on or before April 1, 1999 and thereafter. The Seller believes that the costs of all assessment, remediation, testing and integration related to the Seller's plan for becoming Year 2000 Compliant will not have a material adverse effect on the financial condition or operations of the Seller." 1.3. Section 5.1 of the RPA is amended to add, immediately following paragraph (m), the following new paragraphs (n) and (o): "(n) Year 2000 Compliance: Reporting. The Seller will promptly notify the Agent in the event the Seller discovers or determines that any computer application (including those of its suppliers, vendors and customers) (i) that is necessary for the origination, collection, management, or servicing of the Receivables will not be Year 2000 Compliant on or before April 1, 1999 and thereafter, or (ii) that is otherwise material to its or any of its Subsidiaries' business and operations will not be Year 2000 Compliant on a timely basis, except to the extent that, in the case of (ii) above, such failure could not reasonably be expected (a) to have a Material Adverse Effect on the Seller or on the transaction documented under this Agreement, or (b) to result in a Termination Event. Further, the Seller will deliver simultaneously with any quarterly or annual financial statements or reports to be delivered under the Agreement, a certificate signed by an officer of the Seller that no material event, problems or conditions have occurred 3 which in the opinion of management would (i) prevent or materially delay the Seller's plan to become Year 2000 Compliant or (ii) cause Seller's or be likely to cause the representations and warranties or covenants with respect to being or becoming Year 2000 Compliant to no longer be true. (o) YEAR 2000 COMPLIANCE: IMPLEMENTATION: The Seller will cause (i) all computer applications (including those of its suppliers, vendors and customers) that are material to its or any of its Subsidiaries' business and operations to be Year 2000 Compliant on a timely basis, except to the extent that a failure to do so could not reasonably be expected (a) to have a Material Adverse Effect on the Seller or on the transaction documented under this Agreement, or (b) to result in a Termination Event; and (ii) all Receivable Systems to be Year 2000 Compliant at all times on and after April 1, 1999. The Seller will deliver a certificate to the Seller and the Agent, signed by the chief information officer of the Seller, certifying compliance with the foregoing covenant by no later than April 1, 1999." 1.4. Section 8.1 of the RPA is amended (a) to replace the period appearing at the end of clause (xviii) with a semicolon followed by the word "or" and (b) to add the following new clause (xix): "(xix) any failure of the computer applications of the Seller or any Transferring Affiliate(including those of suppliers, vendors and customers of the Seller or any Transferring Affiliate and the Receivables Systems) to be Year 2000 Compliant at any time." SECTION 2. CONDITIONS PRECEDENT. This Amendment shall become effective and be deemed effective as of the date hereof upon the receipt by the Agent of each of the following: (i) counterparts of this Amendment duly executed by the Purchaser and the Seller; and (ii) a reaffirmation of the Parent Agreement, substantially in the form of Exhibit A attached hereto, duly executed by each of FMC and FMCH.

COVENANTS, REPRESENTATIONS AND WARRANTIES OF THE SELLER. 3.1 Upon the effectiveness of this Amendment, the Seller hereby reaffirms (subject to the modifications to Exhibit F to the RPA set forth in the Certificate of even date herewith executed by the Seller) all covenants, representations and warranties made by it in the RPA and agrees that all such covenants, representations and warranties shall be deemed to have been remade as of the effective date of this Amendment. 4 3.2 The Seller hereby represents and warrants that (i) this Amendment constitutes the legal, valid and binding obligation of such party, enforceable against it in accordance with its terms and (ii) upon the effectiveness of this Amendment, no Seller Default or Potential Seller Default shall exist under the RPA.
