                                SUPPLY AGREEMENT

         THIS SUPPLY AGREEMENT (this "Agreement"), entered into as of the 5th
day of May, 2004 ("Effective Date"), is between ROCKWELL MEDICAL TECHNOLOGIES,
INC., a Michigan corporation ("ROCKWELL"), and DAVITA INC. ("DAVITA"), a
Delaware corporation.

                                    RECITALS

         A.       ROCKWELL is in the business of manufacturing and selling the
dialysis products known as Dri-Sate(R) Dry Acid, Liquid Acid, Powder Bicarbonate
and SteriLyte(R) Liquid Bicarbonate, and the cleaning agents, as more
particularly described in Exhibit A attached hereto and incorporated herein by
this reference (the "Products");

         B.       DAVITA is in the business of owning (in whole or in part) or
managing and operating dialysis clinics, which business requires the purchase
and use of supplies such as the Products; and

         C.       DAVITA desires to purchase the Products listed in Exhibit A
from ROCKWELL, on the terms and conditions contained in this Agreement.

         Therefore, the parties hereby agree as follows:

         1.       Purchase of Products. During the Term (as hereinafter
defined), ROCKWELL will sell to DAVITA such Products and in such quantities as
DAVITA may from time to time order, at the prices as set forth in Exhibit A, in
the states and in accordance with the service expansion time line set forth in
Exhibit B (hereinafter defined as the "Territory"). Other states may be added to
the Territory, and other ancillary dialysis products may be added to the
Products to be sold hereunder, during the Term of this Agreement, but only upon
the mutual written consent of both parties. ROCKWELL understands and
acknowledges that DAVITA has not promised or committed to purchase any
particular quantity of any of the Products or any particular percentage of its
requirements for items such as the Products except as set forth in Section 3.b.

         2.       Term. The term of this Agreement shall commence May 5, 2004
and continue for a period of three years (the "Term"), unless sooner terminated
in accordance with section 9 below. Upon its expiration, the Term of the
Agreement may be extended annually upon the written agreement of both parties.

         3.       Purchase Price.

         a.       The purchase price for the Products shall be determined [* *]
                  as set forth in Exhibit A. [*

                                                                              *]

                                                                              ]*

         b.       [*
















                                           *]

         4.       [*








                                                                              *]

         5.       Delivery Limitations. The Purchase Prices set forth in Exhibit
A cover standard shipping within the Territory for all Products, F.O.B.
Destination. Notwithstanding the foregoing, all orders for Products to be
shipped by ROCKWELL shall be subject to ROCKWELL's minimum purchase requirements
and other shipping requirements set forth in Exhibit C. In the event DAVITA
requires Products to be shipped outside of the Territory or requires some
deviation from the minimum purchase requirements and other shipping requirements
set forth in Exhibit C, ROCKWELL and DAVITA must agree beforehand on any
increase in the purchase price with respect to such Products to cover any
additional delivery costs. Any Products shipped internationally shall be shipped
FOB from any ROCKWELL plant.

         6.       [*




                                                                              *]

                                                                   *]

         8.       Failure to Perform Supply Obligation.

         a.       In the event ROCKWELL cannot supply or does not deliver any
Product(s) (whether as a result of force majeure or otherwise) within and for
the time period required by DAVITA, to any clinics that are, as of the date of
this Agreement, already purchasing Products from ROCKWELL or that later do so
under section 4 above, ROCKWELL agrees that it shall give notice as promptly as
is practicable under the circumstances to DAVITA, unless an order of a
regulatory agency or other action arising out of patient safety concerns
requires the giving of shorter notice. In the event ROCKWELL is unable to
fulfill DAVITA'S orders within the Territory at any time during the Term of this
Agreement, DAVITA may, as its sole and exclusive remedy, upon prior notice to
ROCKWELL, seek other suppliers to fill purchase orders for some or all Products
until DAVITA receives notification from ROCKWELL that ROCKWELL will again be
able to deliver Products. If DAVITA is required to purchase Products from a
third party under this Section 8, ROCKWELL will provide DAVITA with a [*

                                                                    ]*,including
legitimate freight charges incurred, in order to obtain similar or equivalent
products from a different supplier(s). If ROCKWELL's inability to supply any
Products exceeds ninety (90) days, DAVITA may, in its sole and absolute
discretion, terminate this Agreement on no less than thirty (30) days notice.

         b.       [*








                                                                              *]

[*
                                    *]

         9.       Termination Default. The following shall constitute a
termination default ("Termination Default") hereunder:

                  a.       substantial breach of the terms of this Agreement
(other than a failure to perform described in Section 8 for which a sole and
exclusive remedy is provided), which breach is not cured, corrected or otherwise
resolved within [*       *] days after written notice by the non-breaching party
(setting forth the particulars of the alleged breach) to the breaching party. A
"substantial breach" shall include a failure to perform any material obligation
hereunder, including without limitation a failure to pay any amount due
hereunder or under any purchase order issued hereunder when due, other than
amounts which DAVITA disputes in good faith; or

                  b.       (i) the institution by or against a party or its
assets of insolvency, receivership or bankruptcy proceedings or any other
material proceedings for the settlement of such party's debts, (ii) a party's
making a general assignment for the benefit of its creditors, or (iii) a party's
dissolution.

         10.      Termination. Upon the occurrence of a Termination Default
hereunder, and only upon such occurrence, the non-defaulting party may terminate
this Agreement immediately upon written notice to the defaulting party.
Termination of this Agreement shall not relieve either party of obligations
incurred prior to the effective date of termination, including without
limitation obligations of payment of monies or credits owed at the time of such
termination. The provisions of this Section 10 and of Sections 13
(Confidentiality), 14 (Warranties), 15 (Indemnification and Insurance), 20
(Choice of law), 21 (Attorney fees), 25 (Open Records), 26 (Discounts), and any
other provision the context of which shows the parties intended it to survive,
shall survive any expiration or termination of this Agreement.

         11.      Product Addition. Any products other than those set forth in
Exhibit A may be included under the terms hereof, but only upon the mutual,
written agreement of the parties. Prices for such products shall be negotiated
by the parties in good faith and the agreed prices shall be confirmed in writing
and made a part of this Agreement.

         12.      Training. ROCKWELL agrees to furnish,[*                     *]
complete and appropriate training regarding the use and maintenance of the Dri-
Sate(R) Acid Mixer,[*



         *]

         13.      Confidentiality. Both ROCKWELL and DAVITA agree that this
Agreement represents and contains confidential information which shall not be
disclosed to any third party, or otherwise made public, without prior written
authorization of the other party, except where it is required by law or pursuant
to subpoena or court or administrative order. Neither party shall make any
public announcement (including, without limitation, any press release or other
similar

<PAGE>

announcement) of the matters described in this Agreement without the express
prior written consent of the other party. In the event of such disclosure, both
parties must agree to the language of the disclosure. Each party agrees not to
use, release, publish or distribute any materials or information (including but
not limited to advertising and promotional materials) containing the names,
tradenames, or trademarks of the other party without the express prior written
consent of such other party. Each party and its agents shall keep confidential
and shall hold in trust for the sole benefit of the other, and not disclose or
use except in connection with the performance of its obligations hereunder, any
and all trade secrets and other proprietary and confidential information
regarding the other's business, customers, financial condition, practices or
procedures (including business and clinical practices and protocols and patient
information), whether disclosed by the other or discovered by it. Any breach of
these provisions would cause irreparable harm to the other party, and each party
agrees that it will not interpose the lack of such irreparable harm in any
action to enforce these obligations. Notwithstanding the foregoing, either party
may disclose the terms and the existence of this Agreement to the extent that is
necessary to fulfill its obligations under state or federal securities laws, or
under any exchange or market upon which the security of such party are traded.
Each party agrees to require each of its subcontractors or agents providing
services hereunder to provide reasonable assurance that such subcontractor or
agent will comply with the terms of this Section 13, and any breach of this
provision by any such subcontractor or agent shall be deemed a breach of this
Agreement by the respective party hereto.

14.      Warranties. Each party represents and warrants to the other that this
Agreement (a) has been duly authorized, executed and delivered by it, and (b)
constitutes a valid, legal, and binding agreement enforceable against it in
accordance with its terms. ROCKWELL covenants and agrees that no Product
delivered hereunder [*




                  *] ROCKWELL represents and warrants that it has all rights,
licenses, permits and consents necessary to sell the Products to DAVITA (and to
provide the Mixers to DAVITA), and to perform its obligations hereunder, and
that it shall at all times comply in all material respects with all federal,
state and local laws and regulations applicable to its business and its
performance of its obligations under this Agreement. ROCKWELL further warrants
that the Products purchased pursuant to this Agreement [*







                                                                              *]

ROCKWELL warrants that all Products purchased hereunder (as well as the Mixers)
will be [*

         *] ROCKWELL shall service, maintain and repair the Mixers,[*

                                                                              *]
ROCKWELL will warranty the Mixer free from manufacturer defect for [*   *].
Repair or replacement of the Mixer is the sole and exclusive remedy for breach
of warranty.

         15.      Indemnification and Insurance.

         a.       ROCKWELL agrees to defend, indemnify and hold harmless DAVITA,
its affiliates, successors, assigns, directors, officers, agents and employees
("DAVITA Indemnitees") from and against any and all liabilities, demands,
losses, damages, and/or expenses (including costs, expenses, fines, amounts paid
in settlements or judgments, reasonable attorneys' fees, witnesses' fees,
investigation expenses, and, expenses incident thereto) (collectively referred
to as "Damages") that DAVITA Indemnitees may suffer resulting from. [*





                               *] DAVITA agrees to indemnify, defend, and hold
ROCKWELL, its affiliates, successors, assigns, directors, officers, agents and
employees ("ROCKWELL Indemnitees") harmless from [*









                                       *]

         b.       In the event that any demand or claim is made or suit is
commenced against DAVITA Indemnitees for which ROCKWELL has an indemnity
obligation under this section, written notice of such shall be provided to
ROCKWELL, and DAVITA Indemnitees shall cooperate with ROCKWELL in the defense of
the demand, claim or suit to whatever reasonable extent ROCKWELL requires, and
ROCKWELL shall have the right to compromise such claim to the extent of its own
interest and shall undertake the defense of any such suit. No settlement by
ROCKWELL shall be binding upon DAVITA without DAVITA's prior written consent.
Notwithstanding, if ROCKWELL fails to assume its obligation to defend, DAVITA
Indemnitees may do so to protect their interest and seek reimbursement from
ROCKWELL

         c.       In the event that any demand or claim is made or suit is
commenced against ROCKWELL Indemnitees for which DAVITA has an indemnity
obligation under this section, written notice of such shall be provided to
DAVITA, and ROCKWELL Indemnitees shall cooperate with DAVITA in the defense of
the demand, claim or suit to whatever reasonable extent DAVITA requires, and
DAVITA shall have the right to compromise such claim to the extent of its own
interest and shall undertake the defense of any such suit. No settlement by
DAVITA shall be binding upon ROCKWELL without ROCKWELL's prior written consent.
Notwithstanding, if DAVITA fails to assume its obligation to defend, ROCKWELL
Indemnitees may do so to protect their interest and seek reimbursement from
DAVITA.

         d.       [*








                  *]

         16.      Severability. In the event any provision of this Agreement
shall be held to be invalid or unenforceable in any respect, such provision
shall be enforced to the fullest extent permitted by law and the remaining
provisions of this Agreement shall remain in full force and effect. If any such
invalid portion constitutes a material term of this Agreement, the parties shall
meet and in good faith seek to mutually agree to modify this Agreement so as to
retain, if possible, the overall essential terms of this Agreement.

         17.      Waiver. The failure to insist upon strict adherence to one or
more or all of the provisions of this Agreement on any one or more occasions,
shall not be construed as a waiver, nor shall such course of action deprive a
party of the right thereafter to require strict compliance with same.

         18.      Entire Agreement. This Agreement is the entire agreement
between the parties and supersedes any and all prior agreements and
understandings between the parties, whether oral or written, relating to the
subject matter hereof, including without limitation that certain Supply
Agreement between the parties dated March 7, 2003, all of which are hereby
terminated and superceded by this Agreement.. No amendments or modifications of
the terms of this Agreement, including any conflicting or additional terms
contained in any purchase order, acknowledgment form, or other written document
submitted by either party, shall be binding on either party unless reduced to
writing and signed by duly authorized representatives of both parties, or, in
the case of waiver, signed by the party against whom such waiver is construed.

         19.      Conflicts. To the extent that any provision of any purchase
order, invoice, or any other document, or the terms of any of ROCKWELL'S or
DAVITA'S general policies, procedures or catalogs, conflict with or materially
alter any term of this Agreement, this Agreement shall govern and control.

         20.      Choice of Law. The laws of the State of Delaware, without
regard to principles of conflicts of laws, will govern this Agreement and its
subject matter, construction and the determination of any rights, duties or
remedies of the parties arising out of or relating to this Agreement, its
subject matter or any of the transactions contemplated by this Agreement.

         21.      Attorney Fees. In the event of any litigation arising out of
this Agreement, the prevailing party in any such litigation shall be entitled to
recover its reasonable attorneys' fees

<PAGE>

and costs and expenses of litigation from the non-prevailing party as shall be
approved by a court.

         22.      Notices. All notices, requests, demands, and other
communications under this Agreement shall be in writing and shall be deemed to

Any party may change its address for purposes of this paragraph by giving the
other party written notice of the new address in the manner set forth above.

         23.      Successors and Assigns. Neither party may assign this
Agreement to a third party without the prior written consent of the other party,
such consent not to be unreasonably withheld, conditioned, or delayed.
Notwithstanding the foregoing, either party may, without the consent of the
other, assign this Agreement to any entity that controls, is controlled by, or
is under common control of such party. This Agreement shall bind and inure to
the benefit of the parties hereto and their respective heirs, executors,
administrators, legal representatives, successors, and assigns.

         24.      Force Majeure. Unless otherwise stated herein, all obligations

strike, lockout, labor trouble, failure of public utilities, injunction,
accident, epidemic, riot, insurrection, or any other circumstances beyond the
reasonable control of the party asserting it (and not caused by the negligence
of the non-performing party), which prevents or delays the performance by such
party of any of its obligations under this Agreement. However, if any such
circumstances persist for longer than thirty (90) days, the unaffected party may
terminate this Agreement effective at the end of such thirty (90)-day period.

<PAGE>

         25.      Open Records. To the extent required by Section 1861(v)(1)(I)
of the Social Security Act, as amended, the parties will allow the U.S.
Department of Health and Human Services, the U.S. Comptroller General and their
duly authorized representatives, access to this Agreement and records necessary
to verify the nature and extent of costs incurred pursuant to it during the Term
and for four years following the last date Products are furnished under it. If
ROCKWELL carries out the duties of this Agreement through a subcontract worth
$10,000 or more over a 12-month period with a related organization, the
subcontract shall also contain an access clause to permit access by the U.S.
Department of Health and Human Services, the U.S. Comptroller General, and their
duly authorized representatives to the related organization's books and records.
Nothing in this paragraph is intended to waive any right either party may have
under applicable law or regulations to retain in confidence information included
in records so requested.

         26.      Discounts. Any discounts, rebates, incentives, or other
reductions in price issued by ROCKWELL to DAVITA under this Agreement may
constitute a discount within the meaning of 42 U.S.C. Section 1320a-7b
(b)(3)(A). DAVITA may have an obligation to properly disclose and appropriately
reflect such discount to any state or federal program that provides cost or
charge based reimbursement to DAVITA for the items to which the discount
applies. DAVITA will retain invoices and related pricing documentation and make
them available on request to healthcare program representatives. In order to
assist DAVITA's compliance with any such obligations, ROCKWELL agrees that it
shall fully and accurately report all discounts on the invoices or statements
submitted to DAVITA; or where the value of a discount is not known at the time
of sale, ROCKWELL shall fully and accurately report the existence of the
discount program on the invoices or statements submitted to DAVITA, and when the
value of the discount becomes known, provide DAVITA with documentation of the
calculation of the discount identifying the specific goods or services purchased
to which the discount will be applied. ROCKWELL shall also provide to DAVITA any
other information that DAVITA may request that is necessary for it to obtain in
order to comply with any such obligations.

         27.      Changes in Reimbursement Systems. The parties acknowledge and
agree that the health care industry in which DAVITA operates is subject to
constant and rapid fluctuation in many areas, including industry growth,
consolidation and changes in reimbursement systems. Accordingly, the parties
agree that (i) in the event of an increase in the number of facilities owned or
managed by DAVITA, which facilities are not already purchasing Products from
ROCKWELL; or (ii) in the event of any significant change in reimbursement
systems or in reimbursement laws, or in the event of the actual enactment of any
federal, state or local law or regulation, or the actual enactment of any
reimbursement rule, guideline, final program memorandum, coverage decision,
pricing decision, instruction or the like by the Centers for Medicare and
Medicaid Services or any of Customer's Medicare fiscal intermediaries, or the
actual inclusion of reimbursement systems that in any manner reforms, modifies,
alters, restricts or otherwise affects the reimbursement available to DAVITA for
the Products or its services, the parties shall meet and confer in good faith
within thirty (30) days following DAVITA's request. Any modification must be
mutually agreed to by the parties and set forth in a written amendment to this
Agreement.


<PAGE>
         28.      Acquired Facilities. If DAVITA acquires any dialysis facility
or facilities during the Term which has a pre-existing agreement with ROCKWELL
for the purchase of any Products ("Acquired Facility"), ROCKWELL agrees that
DAVITA may determine, [*




                                                               *]

         29.      Counterparts. This Agreement may be executed in counterparts
both of which shall be deemed to be originals. Captions are intended for
convenience of reference only.

         30.      Relationship. Neither party is in any way the legal
representative or agent of the other nor authorized or empowered to assume any
obligation of any kind, implied or expressed, on behalf of the other party,
without the express written consent of the other. This Agreement shall not
constitute, create or in any way be interpreted as a joint venture or
partnership of any kind.

         31.      Joint Preparation. Each party to this Agreement (a) has
participated in the preparation of this Agreement; (b) has read and understands
this Agreement; and (c) has been represented by counsel of its own choice in the
negotiation and preparation of this Agreement. Each party represents that this
Agreement is executed voluntarily and should not be construed against any party
hereto solely because it drafted all or a portion hereof.

         32.      Compliance with [*            *] The parties agree to
negotiate in good faith to amend this Agreement and/or enter into such
additional agreements to the extent deemed necessary or appropriate by DAVITA in
connection with any disclosure by DAVITA to ROCKWELL of any patient information
(including any individually identifiable health information) and/or to comply
with DAVITA's [*                                    *], or any federal or state
regulations or statutes related to privacy of health information. Simultaneously
upon execution of this Agreement, DAVITA has delivered to ROCKWELL a copy of all
applicable [*                                   *] in effect on the date hereof,
and ROCKWELL acknowledges receipt of same and agrees to be bound by the
requirements set forth therein. During the term of this Agreement, DAVITA shall
provide to ROCKWELL, from time to time, with additional [*
*] as they become effective,[*                             *], at least thirty
(30) days prior to the effective date of each [*                *]. ROCKWELL and
DAVITA reserve the right to renegotiate this Agreement in good faith if any such
changes materially increase ROCKWELL's cost and expenses.

         33.      Good Product Support Services for the Products. Without
limitation of the provisions of Section 34 below, ROCKWELL agrees that it may
from time to time provide to DAVITA certain good product support services (the
"Services"), at no additional cost or charge, but only to the extent that such
can be accomplished without using any individually identifiable health
information (as such term is defined in the Health Insurance Portability and
Accountability Act of 1996 ("HIPAA") codified at 45 C.F.R. parts 160 and 164).
Any such Services shall be limited to those Services agreed to in writing from
time to time between ROCKWELL and DAVITA ("Services Agreement"). ROCKWELL agrees
to furnish such Services only in cooperation with

<PAGE>

DAVITA, in a manner consistent with the policies and procedures of DAVITA, and
in accordance with the terms otherwise set forth in this Agreement, including
without limitation Section 34 hereof. Furthermore, ROCKWELL and DAVITA agree to
provide their respective staff members with appropriate training regarding
