Agreement and Plan of Merger, dated as of the date hereof (as it may be amended from time to time, the “Merger Agreement”), which provides for, among other things, the merger of Merger Sub with and into the Company (the
“Merger”) with the Company continuing as the surviving company of the Merger and pursuant to which all Class B Units in the Company will be converted into the right to receive the consideration set forth in the Merger Agreement (the

 WHEREAS, the Interest Holder is the direct owner of 72,711,090 outstanding equity
interests of the Company; and 
 WHEREAS, as a condition and material inducement to the willingness of Parent and Merger Sub to

hereof through the Expiration Date, at every meeting of the Members of the Company, and at every adjournment or postponement thereof, and on every action or approval by written consent of the Members of the Company, the Interest Holder (in the
Interest Holder’s capacity as such), to the extent not voted by the Person(s) appointed under the Proxy, shall, or shall cause the holder of record of its Equity Interests on any applicable record date to, vote all Equity Interests that are

(b) In the event that a meeting of the Members of the Company is held, the Interest Holder shall, or shall cause the
holder of record of the Equity Interests on any applicable record date to, appear at such meeting or otherwise cause the Equity Interests to be counted as present thereat for purposes of establishing a quorum. 

(c) The Interest Holder shall not enter into any agreement or understanding with any Person to vote or give instructions
in any manner inconsistent with the terms of this Section 3.

Sub to the extent arising out of a breach of this Agreement or the Merger Agreement by Parent. 
 5. Irrevocable Proxy.
Concurrently with the execution of this Agreement, the Interest Holder shall deliver to Parent a proxy in the form attached hereto as Exhibit A (the “Proxy”), which shall be irrevocable until following the Expiration

(c) Ownership of Equity Interests. The Interest Holder (i) is the sole record and beneficial owner of the
Company Common Units set forth on the signature page of this Agreement, all of which are free and clear of any Encumbrances (other than transfer restrictions in the Governing Documents of the Company and under applicable securities

 (e) No Finder’s Fees. No

arrangements made by or on behalf of the Interest Holder in its capacity as such. 
 (f) Reliance by

covenants, and agreements contained herein. 
 9. Certain Restrictions. The Interest Holder shall not, directly or
indirectly, take any action that would make any representation or warranty of the Interest Holder contained herein untrue or incorrect in any material respect. 
 10. Disclosure. The Interest Holder shall permit Parent to publish and disclose in all documents and schedules filed with the SEC, including the Prospectus and the Financing Registration Statement,
any document in connection with the Financing, and any press release or other disclosure document that Parent reasonably determines to be necessary or desirable in connection with the Merger and any transactions related to the Merger, the Interest
Holder’s identity and ownership of Equity Interests and the nature of the Interest Holder’s commitments, arrangements, and understandings under this Agreement. 
 11. No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent any direct or indirect ownership or incidence of ownership of or with respect to any Equity
Interests. Except as provided in this Agreement, all rights, ownership, and economic benefits relating to the Equity Interests shall remain vested in and belong to the Interest Holder. 

12. Further Assurances. Subject to the terms and conditions of this Agreement, upon request of Parent, the Interest Holder shall
use commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary to fulfill such Interest Holder’s obligations under this Agreement. 

13. Stop Transfer Instructions. At all times commencing with the execution and delivery of this Agreement and continuing until the
Expiration Date, in furtherance of this Agreement, the Interest Holder hereby authorizes the Company to record a stop transfer order with respect to all of the Equity Interests of the Interest Holder (and to give notice that this Agreement places
limits on the voting and transfer of such Equity Interests), provided that such stop transfer order and notice will immediately be withdrawn and terminated following the Expiration Date.

 14. Termination. This Agreement and the Proxy, and all rights and obligations of the
parties hereunder and thereunder, shall terminate and shall have no further force or effect as of the Expiration Date. Notwithstanding the foregoing, nothing set forth in this Section 14 or elsewhere in this Agreement shall relieve any
party hereto from liability, or otherwise limit the liability of any party hereto, for any intentional breach of this Agreement prior to such termination. This Section 14 and Sections 1 and 15 (as applicable) shall
survive any termination of this Agreement. 
 15. Miscellaneous. 

(a) Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being
enforced under any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect, provided, that the economic and legal substance of the actions set forth herein is not affected in
any manner materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to
effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the Transactions are consummated as originally contemplated to the greatest extent possible. 

(b) Assignment. This Agreement may not be assigned by operation of Law or otherwise without the express written
consent of the parties hereto (which consent may be granted or withheld in the sole discretion of the parties hereto), as the case may be, and any attempted assignment without such consent shall be null and void; provided, however,
that Parent shall have the right to assign this Agreement to a direct or indirect wholly owned subsidiary of Parent; provided, further, that any such assignment shall not relieve Parent of its obligations hereunder. 

(c) Amendments; Waiver. This Agreement may not be amended or modified except by an instrument in writing signed by,
or on behalf of, each of the parties hereto. Any party to this Agreement may (a) extend the time for the performance of any of the obligations or other acts of any other party; (b) waive any inaccuracies in the representations and
warranties of any other party contained herein or in any document delivered by any other party pursuant to this Agreement; or (c) waive compliance with any of the agreements of any other party or conditions to such obligations contained herein.
Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the parties to be bound thereby. Notwithstanding the foregoing, no failure or delay by any party hereto in exercising any right hereunder shall
operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or future exercise of any other right hereunder. The failure of any party hereto to assert any of its rights hereunder shall not constitute a waiver of
any of such rights. 
 (d) Specific Performance; Injunctive Relief. Each of the parties hereto
acknowledges that a breach or threatened breach by any party of any of their obligations under this Agreement (including failing to take such actions as are required of it hereunder to consummate the Transactions) would give rise to irreparable harm
to the 

  
 6 








 
other parties to this Agreement (in each instance, a “Non-Breaching Party”) for which monetary damages would not be an adequate remedy and hereby agrees that in the event of a
breach or a threatened breach by a party of any such obligations, any Non-Breaching Party shall, in addition to any and all other rights and remedies that may be available to it in respect of such breach, be entitled to equitable relief, including a
temporary restraining order, an injunction, specific performance, and any other relief that may be available from a court of competent jurisdiction (without any requirement to post bond or other security). 

(e) Notices. All notices, requests, claims, demands and other communications under this Agreement shall be in
writing and shall be deemed to have been duly given (a) when delivered in person, (b) upon confirmation of receipt after transmittal by email (to such address specified below or another address as such Person may subsequently specify by
proper notice under this Agreement), with a confirmatory copy to be sent by overnight courier, and (c) on the next Business Day when sent by national overnight courier, in each case to the respective parties at the following addresses (or at
such other address for a party as shall be specified in a notice given in accordance with this Section 15(e)):

 EXHIBIT A 

IRREVOCABLE PROXY 
 The undersigned Interest Holder (the “Interest Holder”) of HEALTHCARE PARTNERS HOLDINGS, LLC, a California limited liability company (the “Company”), hereby irrevocably
(to the fullest extent permitted by law) appoints DAVITA INC., a Delaware corporation (“Parent”), acting through any of its Chief Executive Officer, Chief Financial Officer, or General Counsel, as the sole and exclusive attorneys
and proxies of the undersigned, with full power of substitution and resubstitution, to vote and exercise all voting and related rights (to the full extent that the undersigned is entitled to do so) with respect to all of the equity interests of the
Company that now are or hereafter may be beneficially owned by the undersigned, and any and all other equity securities of the Company issued or issuable in respect thereof on or after the date hereof (collectively, the “Equity
Interests”) in accordance with the terms of this Irrevocable Proxy until the Expiration Date (as defined below); provided, however, that such proxy and voting and related rights are expressly limited to the matters discussed
in clauses (i) through (iii) in the fourth paragraph of this Irrevocable Proxy. Upon the undersigned’s execution of this Irrevocable Proxy, any and all prior proxies given by the undersigned with respect to any Equity Interests are
hereby revoked and the undersigned agrees not to grant any subsequent proxies with respect to the Equity Interests until after the Expiration Date. 
 This Irrevocable Proxy is irrevocable to the fullest extent permitted by law, is coupled with an interest, and is granted pursuant to that certain Voting Agreement, dated as of the date hereof, by and
among Parent, the Company, and the undersigned Interest Holder (the “Voting Agreement”), and is granted as a condition and material inducement to the willingness of Parent and Seismic Acquisition LLC, a California limited liability
company and direct, wholly owned subsidiary of Parent (“Merger Sub”), to enter into the Agreement and Plan of Merger, dated as of the date hereof (as it may be amended from time to time, the “Merger Agreement”),
among Parent, Merger Sub, and the Company. The Merger Agreement provides for, among other things, the merger of Merger Sub with and into the Company (the “Merger”) with the Company continuing as the surviving company of the Merger
and pursuant to which all Class B Units of the Company will be converted into the right to receive the consideration set forth in the Merger Agreement (the “Merger Consideration”). The Interest Holder hereby (a) affirms that
such irrevocable proxy is (i) coupled with an interest by reason of the Merger Agreement and (ii) executed and intended to be irrevocable in accordance with the CLLCA, (b) revokes any and all prior proxies granted by such Interest
Holder with respect to the Equity Interests and no subsequent proxy shall be given by the Interest Holder (and if given shall be ineffective) and (c) ratifies and confirms all that the proxies appointed hereunder may lawfully do or cause to be
done in compliance with the express terms hereof. 
 As used herein, the term “Expiration Date” shall mean the
earliest to occur of (i) such date and time as the Merger Agreement shall have been validly terminated pursuant to Article IX thereof and (ii) such date and time as the Merger shall become effective in accordance with the terms and
provisions of the Merger Agreement.

 The attorneys and proxies named above, and each of them, are hereby authorized and empowered
by the undersigned, at any time prior to the Expiration Date, to act as the undersigned’s attorney and proxy to vote the Equity Interests, and to exercise all voting, consent, and similar rights of the undersigned with respect to the Equity
Interests (including, without limitation, the power to execute and deliver written consents) at every annual, special, adjourned, or postponed meeting of Members of the Company and in every written consent in lieu of such meeting: 

(i) in favor of the approval of the principal terms of the Merger and the Merger Agreement, and in favor of any related proposal
necessary to consummate the Merger and the transactions contemplated by the Merger Agreement; 
 (ii) in favor of any
adjournment of such meeting, if necessary, to permit further solicitation and vote of proxies if there are insufficient votes at the time of such meeting to approve the principal terms of the Merger and the Merger Agreement; and 

(iii) against any of the following actions (other than (x) the Merger and any other transactions contemplated by the Merger
Agreement or (y) acquisitions referred to in Section 6.01(b)(vii) of the Company Disclosure Schedule): (A) any merger, consolidation, business combination, sale of assets, reorganization, or recapitalization of or involving the
Company or any of the Business Entities or Related Consolidated Entities, (B) any sale, lease or transfer of all or substantially all of the assets of the Company or any of the Business Entities or Related Consolidated Entities, (C) any
reorganization, recapitalization, dissolution, liquidation or winding up of the Company or any of the Business Entities or Related Consolidated Entities, (D) any material change in the capitalization of the Company or any of the Business
Entities or Related Consolidated Entities, or the corporate structure of the Company or any of the Business Entities or Related Consolidated Entities, or (E) any other action that is intended, or would reasonably be expected to, materially
impede, interfere with, delay, postpone, discourage, or adversely affect the Merger or any other transactions contemplated by the Merger Agreement or result in a breach in any material respect of the Merger Agreement. 

The attorneys and proxies named above may not exercise this Irrevocable Proxy on any other matter. The undersigned Interest Holder may
vote the Equity Interests in its sole discretion on all other matters. 
 Any obligation of the undersigned hereunder shall be
binding upon the successors and permitted assigns of the undersigned. 
 This Irrevocable Proxy shall terminate, and be of no
further force and effect, automatically upon the Expiration Date.
