     1.3 Philip C. Timon. Philip C. Timon (“Timon”) is the managing member of Endowment Capital Group LLC and Endowment Management LLC. By virtue of such positions, Timon has beneficial ownership of the VistaCare securities beneficially owned by the Endowment Entities.

     2.1 Endowment Parties’ VistaCare Holdings. As of the date of this Agreement, the Endowment Parties are the beneficial owners of 2,387,635 shares of the Common Stock of VistaCare, which represents approximately 14.73% of the Common Stock Voting Power of VistaCare, based upon the number of outstanding shares of Common Stock reported in VistaCare’s Annual Report on Form 10-K filed with the Securities and Exchange Commission for the period ended September 30, 2004.

     2.2 Representation of Investment Intent. The Endowment Parties jointly and severally represent and warrant to VistaCare that they have acquired their VistaCare securities in the ordinary course of their business for investment purposes only and not (i) with the purpose, effect or intent of changing or influencing the control of VistaCare; (ii) in connection with, or as a participant in, any transaction having such purpose or effect; or (iii) with the purpose, effect or intention of changing the corporate governance, management or composition of the Board of Directors of VistaCare. The parties agree and acknowledge that the transactions contemplated by this Agreement, including those described in Article III hereof, are not, and shall be deemed not to be, transactions or actions which are prohibited by clauses (i) — (iii) of the preceding sentence.

     2.3 VistaCare Representation Regarding Shareholders Rights Plan. On or about August 18, 2004, VistaCare adopted a Shareholder Rights Plan by entering into a Rights Agreement dated August 18, 2004 with Equiserve Trust Company, N.A. (“Rights Agreement”).

The Company represents and warrants to the Endowment Parties that (i) it has (and its Board of Directors has unanimously) taken all actions necessary under the Rights Agreement to permit the Endowment Entities to acquire shares of VistaCare Common Stock, subject to the percentage Voting Power limitation set forth in Section 3.1 hereof, without the Endowment Entities becoming an Acquiring Person for purposes of the Rights Agreement and without a Distribution Date, Stock Acquisition Date, Section 11(b) Event or Section 13 Event having occurred (as such terms are used in the Rights Agreement) and (ii) it has not taken any action to render the provisions of Section 203 of the Delaware General Corporation Law inapplicable to any person.

     2.4 Purpose of Agreement. The Endowment Parties have requested that the VistaCare Board of Directors approve the acquisition by one or more of the Endowment Entities of additional shares of VistaCare Common Stock representing in excess of fifteen percent (15%) of Voting Power of VistaCare. VistaCare’s Board of Directors is willing to approve such an additional acquisition, subject to the terms and conditions set forth in this Agreement.

     2.5 Definitions

          (a) Capitalized terms used and not defined herein shall have the meanings ascribed to them in the Rights Agreement.

          (b) “Excess Securities” means those shares of the Capital Stock of VistaCare held by the Endowment Entities or any of their Affiliates or Associates that represent 15% or more of the Voting Power of the Company, it being understood that those shares representing less than 15% of the Voting Power of the Company shall be deemed not to be Excess Securities. By way of illustration, in the event the Endowment Entities hold shares representing 20% of the Voting Power of the Company, shares representing 5% of the Voting Power of the Company shall be Excess Securities and shares representing 15% of the Voting Power of the Company shall be deemed not to be Excess Securities.

          (c) “Current Market Price” shall have the meaning set forth in Section 11(f) of the Rights Agreement.

     2.6 Recitals Part of Agreement. The matters set forth in Articles I and II of this Agreement are and shall be deemed material and operative provisions of this Agreement and not mere Recitals.

     3.1 Acquisition of Excess Securities. Subject to the remaining terms and conditions of this Agreement, the Company hereby agrees that the Endowment Entities may become the Beneficial Owner of VistaCare Common Stock representing up to 22.5% of the Voting Power of the Company without the Endowment Entities becoming an Acquiring Person for purposes of the Rights Agreement. The Company hereby acknowledges and agrees that this Agreement shall constitute the Prior Written Approval of the Company (as such term is used in the Rights Agreement) with respect to the transactions contemplated by this Agreement including the acquisition of VistaCare Common Stock referred to above. Notwithstanding the foregoing, the Endowment Entities shall not become Acquiring Persons under the Rights Agreement or be

deemed to violate any provision of this Agreement as the result of an acquisition of voting securities of the Company by the Company or any recapitalization of reclassification of the securities of the Company which increases the proportionate voting power of such securities Beneficially Owned by the Endowment Entities to 22.5% or more of the Voting Power of the Company; provided, however, that if any of the Endowment Entities becomes the Beneficial Owner of Securities constituting 22.5% or more of the Voting Power of the Company by reason of purchases by the Company or a recapitalization or reclassification by the Company and shall, after such purchases by the Company, become the Beneficial Owner of any additional voting securities of the Company without the Prior Written Approval of the Company, then the Endowment Entities shall be deemed to have violated this Section 3.1.

     In the event the Endowment Entities inadvertently become the Beneficial Owner of securities of the Company representing 22.5% or more of the Voting Power of the Company or otherwise become such a Beneficial Owner without a plan or intention to acquire control of the Company, so long as such persons, individually or together with their Affiliates and Associates, promptly enter into, and deliver to the Company, an irrevocable commitment promptly to divest, and thereafter promptly divest (without exercising or retaining any power, including voting, with respect to such securities), sufficient securities of the Company so that such person, together with all Affiliates and Associates of such person, ceases to be the Beneficial Owner of 22.5% or more of the Voting Power of the Company, then such persons shall not be in violation of this Section 3.1 and shall not be deemed to be Acquiring Persons under the Rights Agreement.

     The Endowment Parties expressly acknowledge and agree that the foregoing agreement by the Company does not (i) render the Endowment Entities, or any of them, a Grandfathered Person or (ii) constitute an approval of the acquisition of any VistaCare security by the Endowment Entities for purposes of Section 203(a) of the Delaware General Corporation Law.

     3.2 Governance Matters. In consideration for the rights granted by Section 3.1, the Endowment Parties covenant and agree that neither they, nor any of their respective Affiliates, Associates, officers, directors, or agents will, either alone or in concert with each other or any other person or entity: (i) solicit, publicly encourage or seek to obtain, or cause, solicit, encourage or induce any other person or entity to solicit or seek to obtain, a proxy or other authority to vote with respect to any securities of the Company, including but not limited to the Common Stock of the Company; or (ii) seek to change the control of the Company or change the corporate governance, management or composition of the Board of Directors of VistaCare either alone or in concert with any other participant in any transaction having such purpose or effect until the later of (x) a date which is two (2) years from the date of this Agreement; or (y) the date on which the Endowment Entities cease to own any Excess Securities. Notwithstanding the foregoing, (i) nothing in this Section 3.2 shall prohibit the Endowment Entities from discussing the business and affairs of the Company with management and members of the Board of Directors of the Company; (ii) actions independently taken by Associates, members, shareholders or Beneficial Owners of the Endowment Entities that are not induced or coordinated by or the subject of a contract, agreement, arrangement or understanding with, the Endowment Parties shall not be deemed to violate this Section 3.2.

     3.3 Grant of Proxy.

          (a) In consideration for the rights granted by Section 3.1, the Endowment Parties hereby irrevocably appoint the current Board of Directors of VistaCare, or its designees, with full power of substitution, as their proxy agent(s) (“Proxy Agent”) with the authority to vote any and all Excess Securities held by them on any record date established by the Board of Directors with respect to any meeting of the Company’s shareholders, or any adjournments thereof, with respect to any and all matters to be submitted to the shareholders at such meeting, including but not limited to, the election of Directors, the ratification of officers, the adoption of one or more stock option or benefit plans, any shareholder proposals, merger or other business combination, or other matters to be presented to the shareholders (the “Proxy”).

          (b) The Endowment Parties hereby further agree to execute and deliver upon request and without the payment of additional consideration, such additional documentation as may be reasonably requested by the Board of Directors VistaCare to effectuate the foregoing Proxy, including but not limited to the execution of separate proxy documentation. Notwithstanding the foregoing commitment to execute such additional documentation, the parties hereby agree that a copy of this Agreement may be presented to the Inspector of Elections appointed in connection with any meeting of the shareholders of the Company for purposes of evidencing the grant of the Proxy.

          (c) The Endowment Parties hereby waive any right they or any Affiliate or Associate may have to cancel the Proxy and further agree that the Proxy meets the standards for irrevocability under the Delaware General Corporation Law and that it is coupled with an interest.

     3.4 Control of Proxy. In the event that a vote of the Board of Directors of VistaCare is not unanimous as to any matter as to which the Proxy is to be exercised, the vote of a majority of the Directors appointed hereby as Proxy Agent in attendance at the meeting at which such vote of the Directors is conducted shall control the voting of the Excess Securities. In the event that any current Director should resign or otherwise cease to be a member of the Company’s Board of Directors while the Proxy remains outstanding, then such Director’s status as Proxy Agent and rights to exercise the Proxy shall terminate effective as of the date of such resignation or other termination of Director status, provided that the Proxy shall remain in full force and effect and shall continue to be exercised by the remaining Directors appointed as Proxy Agent by this Agreement.

     3.5 Revocation of Prior Proxies. This Agreement shall serve as a revocation of, and a consent to the revocation of, any proxy previously granted by the Endowment Parties with respect to the Excess Securities.

influence of the control, or the change of the management, corporate governance or composition of the Board of Directors of VistaCare.

The Endowment Parties agree that a bond or other security shall not be a condition of the issuance of such injunction and/or for the ordering of specific performance.
