     This Employment Agreement (this "Agreement") is entered into effective June

intending to be legally bound hereby, agree as follows:

     Section 1.  Employment and Duties.  Employer hereby employs Employee to
                 ---------------------
serve as Chief Operating Officer.  Employee accepts such employment on the terms
and conditions set forth in this Agreement.  Employee shall perform the duties

as may be assigned from time to time by the Chief Executive Officer.  Employee
agrees to devote substantially all of his time, energy, and ability to the
business of  Employer on a full-time basis, provided, however, that from the

date hereof until October 2, 2000, or such earlier date as Employee may
determine (the "Transition Period"), Employee shall be employed on a part-time
basis to enable Employee to complete the transition from his former employer
(the "Transition Activities").  Except for the Transition Activities during the
Transition Period, Employee shall not engage in any other business activities
during the term of this Agreement.  Employee shall at all times observe and
abide by the Employer's policies and procedures as in effect from time to time.

- -------
the Transition Period, which salary shall be increased proportionally to any
significant increase in Employee's workload during the Transition Period.
Employee shall be paid consistent with Employer's payroll schedule. The Base
Salary will be reviewed each year during Employer's annual salary review.
Employer, in its sole discretion, may increase the Base Salary as a result of
any such review.

          2.2  Benefits.  Employee and/or his family, as the case may be, shall
               --------
be eligible for participation in and shall receive all benefits under Employer's
health and welfare benefit plans (including, without limitation, medical,
prescription, dental, disability, and life insurance) under the same terms and
conditions applicable to most executives at similar levels of compensation and
responsibility, provided, however, during the Transition Period, Employee will
                --------  -------
not be entitled to any such benefits until Employee regularly works twenty-four
(24) or more hours per week.

Committee of the Board in his/its sole discretion.

               (b)  Employee must be employed by Employer (or an affiliate) on
the date any Bonus is paid to be eligible to receive such Bonus and, if Employee
is not employed by Employer (or an affiliate) on the date any Bonus is paid for
any reason whatsoever, Employee shall not be entitled to receive such Bonus,
provided, however, that in the event Employee dies or is terminated by Employer
- --------  -------
by reason of Disability (as defined below), Employee (or his estate) shall be
entitled to receive, at such time as bonuses for such year are otherwise paid by
Employer, a pro rated Bonus for that portion of any year prior to such
termination (or for the whole year and a portion of a year if such termination
occurs after December 31 of any year and prior to the date on which the Bonus
for such year is paid) regardless of whether Employee is employed on the date
such Bonus is paid; and provided further, that, in the event Employee is
                        -------- -------
terminated without Material Cause (as defined below) or resigns following

suspend, or discontinue any and all of its health and welfare benefit plans,
practices, policies, and programs

                                       2

               (a)  Employee acknowledges and agrees that: (i) in the course of
his employment by Employer, it will or may be necessary for Employee to create,
use, or have access to (A) technical, business, or customer information,
materials, or data relating to Employer's present or planned business that has
not been released to the public with Employer's authorization, including, but

"Confidential Information") and (B) information and materials that concern
Employer's business that come into Employer's possession by reason of employment
with Employer (collectively, "Business Related Information"); (ii) all
Confidential Information and Business Related Information are the property of
Employer; (iii) the use, misappropriation, or disclosure of any Confidential
Information or Business Related Information would constitute a breach of trust
and could cause serious and irreparable injury to Employer; and (iv) it is
essential to the protection of Employer's goodwill and maintenance of Employer's
competitive position that all Confidential Information and Business Related
Information be kept confidential and that Employee not disclose any Confidential
Information or Business Related Information to others or use Confidential
Information or Business Related Information to Employee's own advantage or the
advantage of others.

               (b)  In recognition of the acknowledgment contained in Section
                                                                      -------

Employee), Employee shall: (i) hold and safeguard all Confidential Information
and Business Related Information in trust for Employer, its successors, and
assigns; (ii) not appropriate or disclose or make available to anyone for use
outside of Employer's organization at any time, either during employment with
Employer or subsequent to the termination of employment with Employer for any
reason, any Confidential Information and Business Related Information, whether
or not developed by Employee, except as required in the performance of
Employee's duties to Employer; (iii) keep in strictest confidence any
Confidential Information or Business Related Information; and (iv) not disclose
or divulge, or allow to be disclosed or divulged by any person within Employee's
control, to any person, firm, or corporation, or use directly or indirectly, for

               (c)  Employee agrees that all lists, materials, records, books,
data, plans, files, reports, correspondence, and other documents ("Employer
material") used or prepared by, or made available to, Employee shall be and
remain property of Employer. Upon termination of employment, Employee shall

make or retain any copies or extracts thereof.

          4.2. Competition.  Employee agrees that during the term of this
               -----------
Agreement and for a period of one (1) year after the termination of his
employment with Employer for any reason, he shall not: (i) be an officer,
director, consultant, partner, owner, stockholder, employee, creditor, agent,
trustee, independent contractor, or advisor of any individual, partnership,
limited liability company, corporation, independent practice association,
management services organization, or any other entity (collectively, "Person")
that either is in the business of or, directly or indirectly, derives any
economic benefit from providing, arranging, offering, managing, or
subcontracting dialysis services or renal care services; or (ii) directly or
indirectly, own, manage, control, operate, invest in, acquire an interest in, or
otherwise engage in, act for, or act on behalf of any Person (other than
Employer and its subsidiaries and affiliates) engaged in any activity in the
United States or in those countries outside the United States in which Employer
or any of its subsidiaries or affiliates had conducted any business during
Employee's employment hereunder, where such activity is similar to or
competitive with the activities carried on by Employer or any of its
subsidiaries or affiliates. As used herein, the term "dialysis services" or
"renal care services" includes, but shall not be limited to, all dialysis
services and nephrology-related services provided by Employer at any time during
the period of Employee's employment, including, but not limited to,
hemodialysis, acute dialysis, apheresis services, peritoneal dialysis of any
type, staff-assisted hemodialysis, home hemodialysis, dialysis-related
laboratory and pharmacy services, access-related services, Method II dialysis
supplies and services, nephrology practice management, or renal physician/center
network management, and any other services or treatment for persons diagnosed as
having end stage renal disease ("ESRD") or pre-end stage renal disease,
including any dialysis services provided in an acute hospital. The term "ESRD"
shall have the same meaning as set forth in Title 42, Code of Federal
Regulations 405.2101 et seq. or any successor thereto. Employee acknowledges
that the nature of Employer's activities is such that competitive activities
could be conducted effectively regardless of the geographic distance between
Employer's place of business and the place of any competitive business.
Notwithstanding anything herein to the contrary, such activities shall not
include the ownership of 1% or less of the issued and outstanding stock, which
is purchased in the open market, of a public company that conducts business that
is similar to or competitive with the business carried on by the Employer or any
of its subsidiaries or affiliates.

     Employee acknowledges and agrees that the geographical limitations and
duration of this covenant not to compete is reasonable.  In particular, Employee
agrees that his position is national in scope and that he will have an impact on
every location where Employer currently conducts and will conduct business.
Therefore, Employee acknowledges and agrees that, like his position, this
covenant cannot be limited to any particular geographic region.

                                       7


          4.3  Solicitation of Employees.  Employee promises and agrees that he
               -------------------------

business, individual, partnership, firm, corporation, or other entity that is
then in competition with Employer's business or any subsidiary or affiliate of
Employer. Employee also agrees that during his employment and for a period of
one (1) year after the termination of his employment, directly or indirectly,

independent contractor) for any business, individual, partnership, firm,
corporation, or other entity that is then in competition with Employer's
business or any subsidiary or affiliate of Employer. In addition, Employee
agrees that during his employment and for a period of one (1) year after the
termination of his employment, directly or indirectly, that he will not take any
action that may reasonably result in any of Employer's employees going to work
(as an employee or an independent contractor) for any business, individual,
partnership, firm, corporation, or other entity that is then in competition with
Employer's business or any subsidiary or affiliate of Employer.

          4.4  Other solicitation.  Employee promises and agrees that during the
               ------------------
term of this Agreement and for a period of one (1) year after the termination of
his employment for any reason, he shall not, directly or indirectly: (i) induce
any patient or customer of Employer, either individually or collectively, to
patronize any competing dialysis facility; (ii) request or advise any patient,
customer, or supplier of Employer to withdraw, curtail, or cancel such person's
business with Employer; (iii) enter into any contract the purpose or result of

               -----------                                      ---------
be held unenforceable or invalid, the remaining parts hereof shall nevertheless
continue to be valid and enforceable as though the invalid portions had not been
a part hereof. In the event that the area, period of restriction, activity, or
subject established in accordance with this Section 4 shall be deemed to exceed
                                            ---------
the maximum area, period of restriction, activity, or subject that a court of
competent jurisdiction deems enforceable, such area, period of restriction,
activity, or subject shall, for the purpose of Section 4, be reduced to the
                                               ---------
extent necessary to render them enforceable.

          4.6  Equitable Relief.  Employee agrees that any violation by Employee
               ----------------
of any covenant in Section 4 will or would cause Employer to suffer irreparable
                   ---------
injury, the exact amount of which will be difficult to ascertain.  For that
reason, Employee agrees that Employer shall be entitled, as a matter of right,
to a temporary, preliminary, and/or permanent injunction and/or other injunctive
relief, ex parte or otherwise, from any court of competent jurisdiction,
restraining any further violations by Employee.  Such injunctive relief shall be
in addition to and in no way limit any

                                       8


and all other remedies Employer shall have in law and equity for the enforcement
of such covenants and provisions. Employee consents and stipulates to the entry
of such injunctive relief in such a court prohibiting him from any further
violation of the covenants and provisions of Section 4.
                                             ---------

     Section 5.  Excess Parachute Payment.  In the event that any payment or
                 ------------------------
benefit received or to be received by Employee in connection with a Change of
Control, whether payable pursuant to the terms of this Agreement or any other
plan, arrangement or agreement by Employer, any predecessor or successor to
Employer or any corporation affiliated (within the meaning of Section 1504 of
the Internal Revenue Code of 1986, as amended (the "Code")) with Employer or
which becomes so affiliated pursuant to the transactions resulting in a Change
of Control (collectively all such payments are hereinafter referred to as the
"Total Payments"), is deemed to be an "Excess Parachute Payment" (in whole or in
part) to Employee within the meaning of Section 280G of the Code, as in effect
at such time, no change shall be made to the Total Payments to be made in
connection with the Change of Control, except that, in addition to all other
amounts to be paid to Employee by Employer hereunder, Employer shall, within
thirty (30) days of the date on which any Excess Parachute Payment is made, pay
to Employee, in addition to any other payment, coverage or benefit due and owing
hereunder, an amount determined by (i) multiplying the rate of excise tax then
imposed by Code Section 4999 by the amount of the "Excess Parachute Payment"
received by Employee (determined without regard to any payments made to Employee
pursuant to this Section 5) and (ii) dividing the product so obtained by the
                 ---------
amount obtained by subtracting (A) the aggregate local, state and Federal income
tax rates (including the value of the loss of itemized deductions under Section
68 of the Internal Revenue Code) applicable to the receipt by Employee of the
"Excess Parachute Payment" (taking into account the deductibility for Federal
income tax purposes of the payment of state and local income taxes thereon) from
(B) the amount obtained by subtracting from 1.00 the rate of excise tax then
imposed by Section 4999 of the Code.  It is Employer's intention that Employee's
net after-tax position be identical to that which would have obtained had
Sections 280G and 4999 not been part of the Code.  For purposes of implementing
this Section 5, (i) no portion, if any, of the Total Payments, the receipt or
     ---------
enjoyment of which Employee shall have effectively waived in writing prior to
the date of payment of the Total Payments, shall be taken into account, and (ii)
the value of any non-cash benefit or any deferred cash payment included in the
Total Payments shall be determined by Employer's independent auditors in
accordance with the principles of Sections 280G(d)(3) and (4) of the Code.

     The calculation of the excess parachute payment is as follows:  X = Y / (1
- - (A + B + C)), where X is the total dollar amount of the Tax Gross-Up Payment,
Y is the total Excise Tax imposed with respect to such Change in Control
Benefit, A is the Excise Tax rate in effect at the time, B is the highest
combined marginal federal income and applicable state income tax rate in effect,
after taking into account the deductibility of state income taxes against
federal income taxes to the extent allowable, for the calendar year in which the
Tax Gross-Up Payment is made, and C is the applicable Hospital Insurance
(Medicare) Tax Rate in effect for the calendar year in which the Tax Gross-Up
Payment is made.

     Section 6.  Representations, Warranties and Agreements of Employee.
                 ------------------------------------------------------
Employer represents and warrants to Employer that (i) upon the conclusion of the
Transition Period, he will have resigned as an officer and employee of Vivra
Asthma and Allergy, Inc. and all affiliated companies and, as of the date
hereof, is not an officer, director, or employee of any other corporation or
entity, (ii) the performance of this Agreement will not breach any other
agreement or obligation by which Employee is bound to keep in confidence
proprietary information acquired by Employee in confidence or in trust before
employment by Employer and or any agreement restricting or purporting to
restrict his right to perform services for Employer, and (iii) upon the
conclusion of the Transition Period, he will not have taken and will not have in
his possession or control any confidential information or property relating to
any former employer.  Employee agrees that he will not use confidential
information or property of any other employer while employed by Employer.
Employee shall indemnify and hold Employer harmless for any breach of the
representations, warranties, and agreements set forth in Section 6, including
reasonable attorneys' fees and costs of suit.

     Section 7.  Miscellaneous.
                 -------------

          7.1  Mediation of Disputes Concerning Employment. In the event of any
               -------------------------------------------
dispute concerning Employee's employment by Employer, whether or not relating to
this Agreement, Employee and Employer shall first attempt to resolve such
dispute through mediation as provided in this Section 7.1 before instituting any
                                              -----------
action or other proceedings with respect thereto; provided, however, that
                                                  --------  -------
neither party shall be required to utilize such mediation procedures to the
extent that equitable relief is being sought by a party in the good faith belief
that an immediate remedy is required to avoid irreparable injury to such party.
Except as otherwise provided in the proviso to the immediately preceding
sentence, in the event that either party desires to institute litigation or
other legal proceedings to resolve a dispute concerning Employee's employment by
Employer, such party shall first give written notice to the other party setting
forth in detail the nature of the dispute and the facts which such party
believes supports such party's position in such dispute.  The parties shall then
promptly (and, in any event, within ten (10) business days of the giving of
notice of a dispute) engage the services of an impartial, experienced employment
mediator (the "Mediator") under the auspices of JAMS/Endispute (or such other
mediation service as the parties may mutually select) in Los Angeles County,
California.  If the parties cannot mutually agree on the selection of a
Mediator, JAMS/Endispute shall select a Mediator within ten (10) business days
after being advised of the parties' inability to select a Mediator.  Once the
Mediator is selected, the parties shall promptly schedule a mediation session
with the Mediator for a date which is not later than forty-five (45) days after
the date of the selection of the Mediator.  The Mediator shall conduct a one-day
mediation session, attended by both parties and their counsel, in an attempt to
informally resolve the dispute. By oral or written agreement of both parties,
follow-up or additional mediation sessions may be scheduled, but neither party
shall be required to participate in more than one day of mediation.  Neither
party shall be required to submit briefs or position papers to the Mediator, but
both parties shall have the right to do so, subject to such rules and procedures
as the Mediator may establish in his or her sole discretion.  Except as
otherwise agreed by the parties, all written submissions to the Mediator shall
remain confidential as between the submitting party and the Mediator.  The
mediation

                                       10


process shall be treated as a settlement negotiation and no evidence introduced
in the mediation process may be used in any way by either party or any other
person in connection with any subsequent litigation or other legal proceedings
(except to the extent independently obtained through discovery in such
litigation or proceedings) and the disclosure of any privileged information to
the Mediator shall not operate as a waiver of privilege with respect to such
information. Each party shall bear all of its own costs, attorneys' fees and
expenses related to preparing for and attending any mediation conducted under
this Agreement. The fees and expenses of the Mediator and the mediation service
used, if any, shall be borne equally by Employer and Employee.

          7.2  Arbitration.  Except as provided below and in Section 4, any
               -----------                                   ---------
controversy or claim arising out of, relating to, or in any way connected with
this Agreement, any alleged breach thereof, or Employee's employment, which was
not resolved through the use of the mediation procedure set forth in Section
                                                                     -------
7.1, shall be settled by arbitration in accordance with the rules of the
- ---
National Rules for the Resolution of Employment Disputes of the American
Arbitration Association.  Without limiting the general nature of the foregoing,
such claims include, but are not limited to: wage and benefit claims; contract
claims; tort claims; defamation claims; claims for employment discrimination
(statutory or nonstatutory) based on age, race, sex, national origin, color,
religion, disability (perceived, actual, or record of), medical condition,
sexual orientation, and marital status; claims for harassment; and claims for a
violation of federal, state, local, or other government law, constitution,
statute, regulation, or ordinance.  The arbitrator shall apply the appropriate
federal or state law, shall have the authority to interpret this Agreement (but
does not have the power to amend, change, delete, or add any terms), and shall
have the power to determine the appropriate legal or equitable remedy, if any.
The arbitrator's decision, which must be in writing, will be final and binding,
and the arbitrator's award may be entered in any court having jurisdiction
thereof.  The arbitration will be held in a mutually agreeable location in
Southern California.  The arbitrator shall apply California law.

shall be effective only upon receipt.

preparation of this Agreement.  Hence, in any construction to be made of this
Agreement, the same shall not be construed against any party on the basis that
the party was the drafter.  The captions of this Agreement are not part of the
provisions hereof and shall have no force or effect.

          7.8  Execution.  This Agreement may be executed in one or more
               ---------

together shall constitute one and the same instrument.  Photographic or
facsimile copies of such signed counterparts may be used in lieu of the
originals for any purpose.

          7.9  Legal Counsel.  Employee and Employer recognize that this is a
               -------------
legally binding contract and acknowledge and agree that they have had the
opportunity to consult with legal counsel of their choice.

          7.10  Waiver.  The waiver by any party of a breach of any provision of
                ------
this Agreement by the other shall not operate or be construed as a waiver of any
other or subsequent breach of such or any provision.

          7.11  Invalidity of Provision.  In the event that any provision of
                -----------------------
this Agreement is determined to be illegal, invalid, or void for any reason, the
remaining provisions hereof shall continue in full force and effect.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement
effective as of the date and year first written above.
