This Stock Appreciation Rights Agreement is dated as of                     (“Grant Date”) by and between DaVita Inc., a Delaware corporation (“Company”) and Sample Example (“Grantee”) pursuant to the DaVita Inc. 2011 Incentive Award Plan (“Plan”). Capitalized terms that are used but not defined in this document shall have the meanings set forth in the Plan.

1. Grant of SAR.

The Company hereby grants to the Grantee the right (“SAR”) to receive with respect to all or any portion of 12,000 shares (“Base Shares”) of the common stock of the Company (“Common Stock”) a number of shares (“Gain Shares”) of Common Stock with a Fair Market Value equal to the amount by which the Fair Market Value applicable to one share of Common Stock on the date on which the SAR is exercised exceeds a base price of $50.0000 per share (“Base Price”).

2. Term of SAR.

(a) This SAR shall be effective for the period (“Term”) from the Grant Date shown above through June 6, 2016 (“Expiration Date”).

(b) This SAR shall expire and cease to be exercisable on the earlier to occur of:

(i) the Expiration Date,

(ii) the date which is three (3) months after the date on which the Grantee’s membership on the Board of Directors of the Company terminates unless such termination is the result of Grantee’s death (or Grantee dies during the three (3) month period following the termination of his or her membership on the Board of Directors of the Company) or Grantee was disabled (within the meaning of Section 22(e)(3) of the Code) at the time of such termination of membership on the Board of Directors of the Company, or

(iii) the date which is one (1) year from the date of termination of Grantee’s membership on the Board of Directors if such termination is the result of Grantee’s death (or Grantee dies during the three (3) month period following the termination of his or her membership on the Board of Directors of the Company) or Grantee was disabled (within the meaning of Section 22(e)(3) of the Code) at the time of such termination of membership on the Board of Directors.

(iv) Notwithstanding the foregoing, the SAR shall terminate no later than the Expiration Date, regardless of whether or not Grantee remains a member of the Board of Directors of the Company.

3. Exerciseability.

(a) The Base Shares subject to this SAR shall become exerciseable (“vest”) on the dates indicated under the Vesting Schedule above such that this SAR shall be fully exerciseable on the last date listed on such table; provided, however, that such vesting shall cease at the time Grantee ceases to be a member of the Company’s Board of Directors.

(b) These installments shall be cumulative, so that this SAR may be exercised as to any or all of the Base Shares covered by an installment at any time or times after the installment becomes vested and until this SAR terminates.

(c) The foregoing notwithstanding, in the event that either (i) in connection with a “Change of Control” (defined below), the “Acquiror” (defined below) fails to assume, convert or replace this Award, or (ii) your Board service is terminated within the twenty-four (24) month period following a Change of Control by the Company (or the Acquiror) other than for “Cause” (defined below), then, in any such case, the SAR shall automatically vest and become immediately exercisable in its entirety, such vesting to be effective as of immediately prior to the effective date of the Change of Control in the case of (i), and as of the date of termination of the Grantee’s service in the case of (ii).

A “Change of Control” is defined herein as (i) any transaction or series of transactions in which any person or group (within the meaning of Rule 13d-5 under the Exchange Act and Sections 13(d) and 14(d) under the Exchange Act) becomes the direct or indirect “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), by way of a stock issuance, tender offer, merger, consolidation, other business combination or otherwise, of greater than 50% of the total voting power (on a fully diluted basis as if all convertible securities had been converted and all warrants and options had been exercised) entitled to vote in the election of directors of the Company (including any transaction in which the Company becomes a

wholly-owned or majority-owned subsidiary of another corporation), or (ii) any transaction in which assets representing more than 50% of the total gross fair market value of the Company’s assets are sold, provided, however, that no transaction contemplated by clauses (i) through (ii) above shall constitute a Change of Control if both (x) the person acting as the Chief Executive Officer of the Company for the 6 months prior to such transaction becomes the Chief Executive Officer or Executive Chairman of the Board of Directors of the entity that has acquired control of the Company as a result of such transaction (the “Acquiror”) immediately after such transaction and remains the Chief Executive Officer or Executive Chairman of the Board of Directors for not less than one year following the transaction and (y) a majority of the Acquiror’s board of directors immediately after such transaction consist of persons who were directors of the Company immediately prior to such transaction.

“Cause” will mean: (1) a material breach by you of your duties and responsibilities to the extent that they do not differ in any material respect from your duties and responsibilities during the ninety (90)-day period immediately prior to a Change in Control (other than as a result of incapacity due to physical or mental illness) which is demonstrably willful and deliberate on your part, which is committed in bad faith or without reasonable belief that such breach is in the best interests of the Company and which is not remedied in a reasonable period of time after receipt of written notice from the Company specifying such breach; (2) willful misconduct or gross negligence which results in material harm to the Company; (3) your conviction of, or a plea of nolo contendere by you, to a felony or other crime involving fraud or dishonesty; or (4) willful violation of Company policies which results in material harm to the Company.

(d) In the event that the Grantee ceases to be a member of the Company’s Board of Directors (whether by reason of death or otherwise), the number of Base Shares with respect to which this SAR may be exercised shall not be accelerated.

4. Method of Exercising.

This SAR may be exercised by the Grantee upon delivery of the following documents to the Company at its principal executive offices:

(a) Written notice, in the form of a completed exercise election form, specifying the number of full Shares with respect to which the SAR is being exercised; and

(b) Such agreements or undertakings that are required by the Committee pursuant to the Plan.

5. Settlement of SAR.

Upon exercise of the SAR, in whole or in part, the Company shall:

(1) provide for the registration in book-entry form for the Grantee’s benefit of the Gain Shares (rounded down to the nearest whole number), or

(2) deliver to the Grantee a stock certificate representing the Gain Shares (rounded down to the nearest whole number).

6. Clawback Provision.

Nothwithstanding any other provision in this agreement to the contrary, Grantee shall be subject to the written policies of the Company’s Board of Directors applicable to members of the Board, including without limitation any Board policy relating to recoupment or “clawback” of compensation arising from exercise of this SAR, as they exist from time to time during the Grantee’s service on the Board and thereafter.

7. Assignments.

(a) This SAR shall be exercisable only by the Grantee during the Grantee’s lifetime, provided that in the event of the death of the Grantee during his or her service as a member of the Board of Directors of the Company or during the three (3) month period immediately subsequent to the termination of his or her membership on the Board of Directors of the Company, this SAR may be exercised by any of the Grantee’s executor, heirs or administrator to whom this SAR may have been assigned or transferred as provided in Section 7(b) below.

(b) The rights of the Grantee under this SAR may not be assigned or transferred except by will or by the laws of descent and distribution.

8. No Rights as a Stockholder.

The Grantee shall have no rights as a stockholder of any Base Shares or Gain Shares unless and until Gain Shares are issued to him or her following the exercise of this SAR.

9. Interpretation of SAR.

(a) This SAR is made under the provisions of the Plan and shall be interpreted in a manner consistent with it.

(b) Any provision in this SAR inconsistent with the Plan shall be superseded and governed by the Plan.

10. Restrictions on Transfer of Gain Shares.

The Grantee acknowledges that any Gain Shares issued upon exercise of this SAR may be subject to such restrictions on transfer as the Company may deem necessary to comply with all applicable state and federal securities laws and regulations.

11. Amendments.

This SAR may be amended at any time with the consent of the Company and the Grantee.

12. Confidentiality.

Grantee shall not at any time disclose or use for Grantee’s direct or indirect personal benefit or purposes or for the benefit or purposes of any person, firm, partnership, joint venture, association, corporation, or other business organization, entity or enterprise other than the Company or any of its subsidiaries or affiliates (whether during or after the termination of Grantee’s membership on the Board of Directors of the Company), any trade secret, information, data or other confidential information relating to customers, development programs, costs, marketing plans, acquisitions and investments, sales activities, promotions, credit and financial data, financing methods, plans of the business and affairs of the Company generally, or any of its subsidiaries or affiliates; provided, however, that the foregoing shall not apply to (i) information which is not unique to the Company or which is generally known to the industry or the public other than as a result of Grantee’s breach of this Section 11 or (ii) disclosure that is required by any applicable law, rule or regulation (including compliance with any oral or written interrogatories or requests for information or documents pursuant to any subpoena or in connection with discovery proceedings in any litigation or similar process to which Grantee may be subject); provided, however, that Grantee shall provide the Company with at least ten (10) days’ advance written notice of the legal requirement to disclose prior to disclosure and assist DaVita as requested in obtaining a protective order or other similar relief.

13. Non-Solicitation.

Grantee agrees that while Grantee is a member of the Company’s Board of Director’s and for the one-year period following termination of such relationship, Grantee will not (a) directly or indirectly induce any employee of the Company, its affiliates or its subsidiaries to terminate his or her relationship with the Company or any of its affiliates or subsidiaries or (b) take any action that results, or might reasonably result in any of the foregoing. If Grantee breaches this provision, then (1) this SAR shall terminate effective on the date on which Grantee enters into such activity and (2) the Company may seek temporary, preliminary, and permanent injunctive relief to prevent any actual or threatened breach or continuation of any breach of this Agreement without the necessity of proving actual damages or posting a bond or other security (which Grantee hereby agrees to) and/or an order requiring Grantee to repay the Company any gain realized by Grantee from exercising all or a portion of this Grant.

This agreement may be considered null and void at the discretion of the Company if a signed copy is not returned to the Stock Plan Administrator for the Company no later than 120 days from the Grant Date.

In Witness Whereof, the Company and the Grantee have executed this SAR as of the date first written above.
