                                    AGREEMENT
                                    ---------

     This Separation Agreement and Release of Claims ("Agreement") is entered
into by Richard A. Schweinhart and all of his agents, successors and assigns
("Employee"), and Kindred Healthcare, Inc. ("Kindred") and all companies related
to Kindred and all of its affiliates, subsidiaries or related companies, past
and present (collectively, the "Company").

     WHEREAS, Employee and Company hereby desire to settle all disputes and
issues related to the termination of Employee from his services to the Company.

     NOW, THEREFORE, in consideration of the premises and the terms and
conditions contained herein, the receipt and sufficiency of which are hereby
acknowledged, and intending to be legally bound, the parties agree as follows:

          1. Resignation. Employee is hereby terminated without cause and
             -----------
voluntarily resigns from all capacities and positions with the Company effective
February 25, 2002 ("Date of Termination").

          2. Obligations of the Company. Following the execution of this
             --------------------------
Agreement, the Company shall pay Employee his base salary through the Date of
Termination and any amounts owed to Employee pursuant to the Company's standard
reimbursement procedures. In addition, subject to the terms and conditions of
this Agreement (including Section 13), Employee will be entitled to the
following additional payments and benefits:

               (a) $218,820 representing the Employee's maximum bonus for 2001.

               (b) $27,662 representing the prorated portion of the Employee's
target bonus for 2002.

               (c) $450,750 representing an amount equal to one and one-half
times the Employee's base salary for 2002.

               (d) $270,450 representing an amount equal to one and one-half
times the Employee's target bonus for 2002.

               (e) For a period of 18 months following the Date of Termination,
the Employee shall be treated as if he had continued to be an employee for

                                      -1-

<PAGE>

all purposes under the Company's health insurance plans and dental insurance
plans, provided, however, that such benefits shall be provided only as long as
similar benefits are provided to employees of the Company. Employee shall be
responsible for any Employee contributions for such insurance coverage.
Following this continuation period, the Employee shall be entitled to receive
continuation coverage under Part 6 of Title I of ERISA ("COBRA Benefits")
treating the end of this period as a termination of the Employee's employment if
allowed by law.

               (f) For a period of 18 months following the Date of Termination,
the Company shall maintain in force the Employee's life insurance in effect
under the Company's life insurance benefit plans as of the Date of Termination,
provided, however, that such benefits shall be provided only as long as similar
benefits are provided to employees of the Company. Employee shall be responsible
for any Employee contributions for such insurance coverage.

               (g) For a period of 18 months following the Date of Termination,
the Company shall provide short-term and long-term disability insurance benefits
to Employee equivalent to the coverage that the Employee would have had had he
remained employed under the disability insurance plans applicable to Employee on
the Date of Termination, provided, however, that such benefits shall be provided
only as long as similar benefits are provided to employees of the Company.
Should Employee become disabled during such period, Employee shall be entitled
to receive such benefits, and for such duration, as the applicable plan
provides. Employee shall be responsible for any Employee contributions for such
insurance coverage.

               (h) To the extent not already vested pursuant to the terms of
such plan, the Employee's interests under the Company's retirement savings plan
shall be automatically fully vested, without regard to otherwise applicable
percentages for the vesting of employer matching contributions based upon the
Employee's years of service with the Company.

               (i) The Company may adopt such amendments to its employee benefit
plans, if any, as are necessary to effectuate the provisions of this Agreement.

               (j) Employee shall continue to vest in all shares of restricted
common stock of Kindred previously awarded to Employee according to the vesting
schedule set forth in the Employee's Restricted Share Agreement dated May 21,
2001.

               (k) Employee shall be entitled to the unpaid portion of the award
under the Company's Long-Term Incentive Plan ("LTIP") for the 2000 and 2001
performance periods. In addition, if the Board of Directors grants awards under
the LTIP for the 2002 performance period, Employee shall be entitled to 1/12 of
the award

                                      -2-

<PAGE>

Employee would have received if employed by the Company at such time. Employee
acknowledges that any award for 2002 is contingent upon approval by the Board of
Directors of awards under the LTIP for the 2002 performance period. Any amounts
credited to Employee under this Section 2(k) shall be paid at the time and in
the manner specified in Section 6 of the LTIP.

               (l) Employee shall be credited with an additional 18 months of
vesting for purposes of all outstanding stock option awards to purchase Kindred
common stock and Employee will have 18 months in which to exercise such stock
options.

               (m) Employee shall receive the computer that Employee is
utilizing as of the Date of Termination.

               (n) All commitments made to Employee under paragraphs (a) through
(d) above shall be paid upon the later of 14 days from the Date of Termination
or the expiration of the seven-day period referenced in Section 16. All other
commitments shall be paid as provided in this Agreement.

          3. Death after Resignation. In the event of the death of Employee
             -----------------------
during the period Employee is receiving payments pursuant to this Agreement,
Employee's designated beneficiary shall be entitled to receive the balance of
the payments; or in the event of no designated beneficiary, the remaining
payments shall be made to Employee's estate.

          4. Employee Acknowledgment and Release. Employee expressly
             -----------------------------------
acknowledges that the above payments include consideration for the settlement,
waiver, release and discharge of any and all claims or actions arising from
Employee's employment, the terms and conditions of Employee's employment, or
Employee's termination of employment with the Company, including claims of
employment discrimination, wrongful termination, unemployment compensation or
any claim arising under law or equity, express or implied contract, tort, public
policy, common law or any federal, state or local statute, ordinance, regulation
or constitutional provision.

               (a) The claims released and discharged by Employee include, but
are not limited to, claims arising under Title VII of the Civil Rights Act of
1964, as amended; the Civil Rights Act of 1991; The Older Workers Benefit

Laws, claims before the Kentucky Commission for Human Rights and Kentucky

Company.

               (d) Employee expressly waives any present or future claims

admit that it engaged in any discrimination, wrong doing or violation of law on
the Company's part concerning Employee. Employee and the Company agree that by

Company further acknowledge that this Agreement is not an admission of
liability.

          5. Confidentiality. Employee and the Company agree to keep the
             ---------------
contents and terms of this Agreement confidential and not to voluntarily
disclose the terms or amount of settlement to third parties. The only exception
is that Employee may reveal the terms of this Agreement to his spouse, attorney,
tax preparer or as otherwise required by law. The Company may reveal the terms

respective directors, officers, shareholders, agents or employees, to any third
parties, and not to otherwise defame the Company in any manner. In the event
that Employee defames the Company, its affiliates and their respective
directors, officers, shareholders, agents or employees, Employee understands
that the Company shall have the right to pursue all appropriate legal relief,
including but not limited to, attorneys' fees and costs, and

                                      -4-

reimbursement of all monies paid hereunder. Company agrees not to make
derogatory or negative remarks or comments about Employee to any third parties,

signing this Agreement.

about the Company's businesses or operations (except as required by law or order
of court or other governmental agency) or any of the clients, patients,
customers or suppliers of the Company or with respect to any other confidential
aspect of the businesses of the Company. Employee understands and agrees that
any violation of this provision will cause the Company irreparable harm which
cannot adequately be compensated by an award of money damages. As a result,

violation of this Agreement may be restrained by issuance of an injunction by

     Re: Pure Resources, Inc. - Business Opportunities Agreement

Ladies and Gentlemen:

     Reference is made to the Business Opportunities Agreement (the "Agreement")
dated as of December 13, 1999 among Union Oil Company of California ("Union
Oil"), Pure Resources, Inc. (formerly named Titan Resources Holdings, Inc.) (the
"Company"), TRH, Inc., and Titan Exploration, Inc. Capitalized terms used and
not otherwise defined herein shall have the meanings given to them in the
Agreement. The Agreement was entered into to address certain legal requirements
and concerns as well as for certain practical business purposes. Although this
letter does request a limited waiver of the Agreement, we wish to make it clear
that we understand that the Agreement will remain in effect after any grant of a
limited waiver and that we will continue to remain focused on the business we
conduct in the Designated Area and any other area that you may permit us to
operate in pursuant to this or any other limited waiver.

     Pursuant to Section 1 of the Agreement, the Company agreed that, except
with the consent of Union Oil (which it may withhold in its sole discretion),
neither the Company nor its subsidiaries will engage in any business other than
the E&P Business and none of them will pursue any business opportunity that
involves any direct or indirect ownership interest in any properties located
outside the Designated Area.

     On May 9, 2001, you granted the Company a limited waiver of the Agreement
in connection with certain transactions (the "May 9 Limited Waiver"). We hereby
confirm that Agreement remains in full force and effect and that we are
continuing to observe and comply with its terms allowing for the provisions of
the May 9 Limited Waiver.

     The Company has now been presented with exploration opportunities in the
Gulf of Mexico that are not located within the parameters of the Offshore
Extended Business as defined in the May 9 Waiver. In connection therewith, we
hereby request that Union Oil agree that the term "Offshore Extended Business"
be deemed to include the Company's participation in a seven prospect Gulf of

<PAGE>

April 23,2002
Page 2

Mexico shelf drilling program generated and operated by Gryphon Exploration, the
details of which were communicated to Union Oil on April 22, 2002.

     By signing below, Union Oil hereby acknowledges that the Company will not
breach or violate the Agreement by pursuing or engaging in either the Onshore
Extended Business or the Offshore Extended Business (as such terms are defined
in the May 9 Limited Waiver and as the term "Offshore Extended Business" is
modified by this letter). Notwithstanding the foregoing, the limited waiver that
Union Oil grants hereby with respect to the Offshore Extended Business shall
expire and terminate on March 31, 2003 if Union Oil notifies the Company in
writing at any time in the month of September, 2002, that this limited waiver
shall so terminate and that Union Oil will not extend the effective period of
such limited waiver beyond March 31, 2003. If Union Oil notifies the Company in
writing, during the month of September, 2002, that the limited waiver for
Offshore Extended Business shall be extended beyond March 31, 2003, such limited
waiver will be so extended for the period of time set forth in Union Oil's
notification. Union Oil's right to so notify the Company to either terminate or
extend the limited waiver for Offshore Extended Business may be exercised in its
sole discretion.

     We hereby acknowledge that if you agree to the extension of "Offshore
Extended Business" as set forth above, that such extension in no way shall serve
to waive any provision of the Agreement that may be applicable to future
transactions or investments by the Company that are not included within the
Onshore Extended Business or the Offshore Extended Business (as such terms are
defined after execution of this letter). Furthermore, nothing herein shall serve
as a general waiver or be construed as amending or revising in any way the
definition of "Designated Area" in the Agreement or any other provision of the
Agreement.

     By signing below, you agree that nothing in this letter terminates or
revokes any prior waiver of the Agreement previously granted by you.
