This SHAREHOLDER VOTING AGREEMENT (this “Agreement”) is entered into as of December 14, 2009, by and among Fresenius USA, Inc., a Massachusetts corporation (“Acquiror”) and the stockholders of National Quality Care, Inc., a Delaware corporation (the “Company”), identified on Schedule A attached hereto (each a “Stockholder” and collectively, the “Stockholders”).

W I T N E S S E T H:

WHEREAS, as of the date hereof, each Stockholder “beneficially owns” (as such term is defined in Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended) and is entitled to dispose of (or to direct the disposition of) and to vote (or to direct the voting of) that total number of shares of common stock, par value $0.0001 per share (the “Common Stock”), of the Company as are set forth adjacent to such Stockholder’s name on Schedule A attached hereto (the “Owned Shares”), as such shares may be adjusted after the date hereof by stock dividend, stock split, recapitalization, combination, Acquisition, consolidation, reorganization or other change in the capital structure of the Company affecting the Common Stock (such shares of Common Stock, together with any other shares of Common Stock the voting power over which is acquired by a Stockholder during the period from and including the date hereof through and including the date on which this Agreement is terminated in accordance with its terms, are collectively referred to herein as the “Subject Shares”);

WHEREAS, Acquiror, Xcorporeal, Inc. (“Xcorp”), Xcorporeal Operations, a Delaware corporation and a wholly owned subsidiary of the Company (“Operations”) and the Company propose to enter into an Asset Purchase Agreement dated as of the date hereof (the “Purchase Agreement”), pursuant to which Acquiror will purchase certain assets of the Company, Xcorp and Operations (the “Acquisition”); and

WHEREAS, as a condition to the willingness of Acquiror to enter into the Purchase Agreement, and as an inducement and in consideration therefor, Acquiror has required that the Stockholders agree, and the Stockholders have agreed, to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual premises, representations, warranties, covenants and agreements contained herein, the parties hereto, intending to be legally bound, hereby agree as follows:

ARTICLE I
DEFINITIONS

Section 1.1. Capitalized Terms. For purposes of this Agreement, capitalized terms used and not defined herein shall have the respective meanings ascribed to them in the Purchase Agreement.

ARTICLE II
VOTING AGREEMENT AND IRREVOCABLE PROXY

Section 2.1. Agreement to Vote the Subject Shares. Each Stockholder, in its capacity as such, hereby agrees that, during the period commencing on the date hereof and continuing until the termination of this Agreement (such period, the “Voting Period”), at any meeting (or any adjournment or postponement thereof) of the holders of any class or classes of the capital stock of the Company, however called, such Stockholder shall vote or cause to be voted the Subject Shares (a) in favor of the approval of the terms of the Purchase Agreement, the Acquisition and the other transactions contemplated by the Purchase Agreement (and any actions required in furtherance thereof), (b) against any action, proposal, transaction or agreement that would result in a breach in any respect of any covenant, representation or warranty or any other obligation or agreement of the Company under the Purchase Agreement or of such Stockholder contained in this Agreement, and (c) except as otherwise agreed to in writing in advance by Acquiror, against any action or proposal involving the Company that is intended, or could reasonably be expected, to prevent, impede, interfere with, delay, postpone or adversely affect the transactions contemplated by the Purchase Agreement. Any such vote shall be cast or consent shall be given in accordance with such procedures relating thereto so as to ensure that it is duly counted for purposes of determining that a quorum is present and for purposes of recording the results of such vote or consent. During the Voting Period, each Stockholder agrees not to enter into any written or oral contract, agreement, commitment, letter of intent, agreement in principle, or understanding with any Person that violates or conflicts with or could reasonably be expected to violate or conflict with the provisions and agreements contained in this Agreement.

Section 2.2. Grant of Irrevocable Proxy. Each Stockholder hereby appoints Acquiror and any designee of Acquiror, and each of them individually, as such Stockholder’s proxy and attorney-in-fact, with full power of substitution and resubstitution, to cause such Stockholder’s shares to be counted as present at any meeting of the Company’s Stockholders during the Voting Period and to vote or act by written consent during the Voting Period with respect to the Subject Shares in accordance with Section 2.1. This proxy is given to secure the performance of the duties of such Stockholder under this Agreement. Each Stockholder shall promptly cause a copy of this Agreement to be deposited with the Company at its principal place of business. Each Stockholder shall take such further action or execute such other instruments as may be reasonably necessary to effectuate the intent of this proxy. Each Stockholder hereby revokes all other proxies and powers of attorney with respect to its Subject Shares that it may have previously granted, in each case to the extent such prior or subsequent proxies or powers of attorney would prevent such Stockholder from complying with such Stockholder’s obligations under this Agreement.

Section 2.3. Nature of Irrevocable Proxy. The proxy and power of attorney granted pursuant to Section 2.2 by each Stockholder shall be irrevocable during the Voting Period, shall be deemed to be coupled with an interest sufficient in law to support an irrevocable proxy and shall revoke any and all prior proxies granted by such Stockholder. The power of attorney granted by each Stockholder herein is a durable power of attorney and shall survive the dissolution, bankruptcy, death or incapacity of such Stockholder. The proxy and power of attorney granted hereunder shall immediately terminate upon the termination of this Agreement pursuant to Section 5.1.

Section 2.4. Other Rights. Except as provided by this Agreement or the Purchase Agreement, each Stockholder shall exercise the full rights of a holder of capital stock of the Company with respect to the Subject Shares and all economic benefits of and relating to the Subject Shares shall remain vested in and belong to such Stockholder.

Section 2.5. Stockholder Capacity. Each Stockholder is executing this Agreement solely in its capacity as an owner of the Subject Shares, and nothing in this Agreement shall limit or affect any actions taken by such Stockholder in such Stockholder’s fiduciary capacity as an officer or director of the Company.

ARTICLE III

The failure of any party hereto to exercise any right, power or remedy provided under this Agreement or otherwise available in respect hereof at law or in equity, or to insist upon compliance by any other party hereto with its obligations hereunder, and any custom or practice of the parties at variance with the terms hereof shall not constitute a waiver by such party of its right to exercise any such or other right, power or remedy or to demand such compliance.
