ANG shall notify DCA in writing within thirty (30) days of such offer of its intent to Transfer, the number of shares of Common Stock to be Transferred, the consideration to be received and the terms and conditions of the Transfer, all of which shall be evidenced by a bona fide written third party offer to be provided to DCA who may request further information with respect to such proposed Transfer. Thereupon, DCA shall notify ANG in writing within five (5) days of ANG's notification to Transfer with supporting third party documentation as provided for hereinabove, of its deter- mination to acquire the Common Stock proposed to be Transferred by ANG. Upon receipt of the notification by ANG that DCA has determined to acquire the Common Stock, ANG shall Transfer the Common Stock to DCA at the agreed upon price and terms. Closing of the Transfer to DCA and payment of the purchase price shall be effected no later than fifteen (15) days (or other terms as may have been agreed upon) of acceptance of the purchase offer.

The right of first refusal as provided for in this Section 3(b) shall not be applicable and shall be null and void and of no effect should the Corporation not be sold separately, but rather as part of the overall business operations of DCA, including but not limited to a merger or acqui- sition of DCA or its parent, or a tender offer for the shares of DCA or its parent. Further, there is no obligation on behalf of DCA to sell or otherwise dispose of the Corporation.

ANG has fifteen (15) days from the date of such notification to exercise its right to acquire the Corporation for the consideration and under the terms as set forth in the notice as aforementioned, and ANG shall notify DCA in writing within the fifteen (15) day period of its determination to so acquire the Corporation. Upon receipt of such notification, DCA shall sell the Corporation to ANG for the considera- tion and under the terms as then determined. If ANG fails to so notify DCA as set forth herein, or otherwise fails to follow the terms, conditions and procedures for exercising and completing its right to purchase and the purchase of the Corporation, then ANG shall be deemed to have waived this right to so purchase the Corporation and DCA can thereafter deal with its interest in the Corporation as it deems appropriate. (c) Upon the change in control of ANG without the prior written approval of the Corporation, the voluntary or involuntary bankruptcy of ANG, an assignment for the benefit of creditors of the ANG, or other cessation of operations of ANG by operation of law or otherwise (collectively "ANG Termination"), DCA shall have the option to purchase all of the shares of Common Stock of the Corporation owned by ANG or any trustee or similar administrator or agent for ANG ("Trustee") by serving written notice on ANG and/or the Trustee, as the case may be, within thirty (30) days of the notice to DCA of the ANG Termination. The purchase price shall be the book value of the shares of Common Stock as of the close of the immediately preceding fiscal year to be paid upon terms to be agreed to with the Trustee. (d) A Transfer of the Common Stock in any other fashion or manner, other than as provided for in this Agreement shall be a breach of this Agreement, shall not be valid, and such Transfer shall be null and void ab -- initio. - ------ 4.

Intent and Construction. ----------------------- (a) Medical Necessity. Diagnostic, treatment and therapeutic ----------------- services provided by the Facility will be provided only when medically necessary and documented based upon the treating physician's best clinical judgment. Further, each patient shall receive specified and individualized services based upon the patient's own unique circumstances. (b) Factors Demonstrating Compliance Intent. Neither the Corporation --------------------------------------- nor ANG shall undertake any conduct to induce referrals to the other party and it is the specific intent of the parties to absolutely comply with all federal and state laws. The parties have undertaken due diligence to develop an appropriate and lawful structure demonstrated by the following factors: (b)(1) Access. An increase in access to health care services ------ will result because of the availability of additional dialysis stations resulting from this new Facility. (b)(2) Quality. An increase in the quality of health care ------- services will exist because state of the art diagnostic, treatment and therapeutic techniques will be utilized. (b)(3) Freedom of Choice. An increase in patient freedom of ----------------- choice among health care providers will exist because patients will now be able to choose between more than one renal dialysis facility in the Corporation's market area. (b)(4) Increased Competition. An increase in competition --------------------- among health care providers will occur for the same reason as stated in subparagraph (b)(3). (b)(5) No Cost Increase. No increase in costs to the Medicare ---------------- program will exist because these services are required and medically necessary. (b)(6) Physicians' Judgment Unaffected. The physicians' ------------------------------- judgment will not be altered because a significant demand exists to treat patients suffering from kidney failure or illnesses sufficient to warrant renal dialysis or other Services to be provided by the Corpora- tion and ANG, and the physician's judgment will not be varied or in- fluenced by any conduct of the Corporation; physicians' judgment will be based solely on demonstrable clinical necessity for the services. (b)(7) No Inducement. The Corporation shall undertake no ------------- conduct to influence any referrals by ANG inasmuch as fair market value fees for Medical Director services will be paid pursuant to the MD Agreement. 11. Documents. DCA and ANG shall execute all necessary documents --------- required to carry out the terms of this Agreement. 12. Entire Agreement.

Other than the MD Agreement, there are no other understandings or agreements between them. 6 13. Non-Waiver.
