         This Warrant Certificate certifies that the registered holder hereof or
registered assigns (the "Holder"), is entitled to purchase from Rockwell Medical
Technologies, Inc., a Michigan corporation (the "Company"), at any time after

(unless the Warrants are earlier redeemed), at the purchase price of $____ per
share (the "Warrant Price"), the number of Common Shares of the Company (the
"Common Shares") which is equal to the number of Warrants set forth above. The
number of Common Shares purchasable upon exercise of this Warrant and the
Warrant Price per share shall be subject to adjustment from time to time as set
forth in the Warrant Agreement referred to below. These Warrants are subject to
call and repurchase by the Company on the terms and conditions contained in such
Warrant Agreement.

         This Warrant may be exercised in whole or in part by presentation of
this Warrant with the Purchase Form on the reverse side hereof duly executed and
simultaneous payment of the Warrant Price (subject to adjustment) at the
principal office of American Stock Transfer & Trust Company (the "Warrant
Agent"). Payment of such price shall be made at the option of the Holder hereof
in cash or by check or wire transfer, or any combination thereof.

         This Warrant is one of a duly authorized issue of Warrants evidencing
the right to purchase an aggregate of up to 3,625,000 Common Shares and is
issued under and in accordance with a Warrant Agreement (the "Warrant

         Upon any partial exercise of this Warrant, there shall be countersigned
and issued to the Holder hereof a new Warrant in respect to the Common Shares as
to which this Warrant shall not have been exercised. This Warrant may be
exchanged at the office of the Warrant Agent by surrender of this Warrant
properly endorsed either separately or in combination with one or more other
Warrants for one or more new Warrants entitling the Holder thereof to purchase
the same aggregate number of shares as were purchased on exercise of the
Warrants or Warrants exchanged. No fractional shares will be issued upon the
exercise of this Warrant, but the Company shall pay the cash value of any
fraction upon the exercise of one or more

Warrants. This Warrant is transferable at the office of the Warrant Agent, 59
Maiden Lane, New York, New York 10038, in the manner and subject to the
limitations set forth in the Warrant Agreement.

         The Company shall not be obligated to deliver any securities pursuant
to the exercise of this Warrant unless a registration statement under the
Securities Act of 1933, as amended (the "Act"), with respect to such securities
is effective or an exemption thereunder is available. The Company has covenanted
and agreed that it will file a registration statement under the Federal
securities laws, use its best efforts to cause the same to become effective, to
keep such registration statement current, if required under the Act, while any
of the Warrants are outstanding, and deliver a prospectus which complies with
Section 10(a)(3) of the Act to the registered Holder exercising this Warrant.
This Warrant shall not be exercisable by a registered Holder in any state where
issuance of Common Shares pursuant to exercise, or the offer of Common Shares
under this Warrant, would be or is unlawful.

         The Holder hereof may be treated by the Company, the Warrant Agent, and
all other persons dealing with this Warrant as the absolute owner hereof for any
purpose and as the person entitled to exercise the rights represented hereby, or
to the transfer hereof on the books of the Company, any notice to the contrary
notwithstanding, and until such transfer on such books, the Company may treat
the Holder hereof as the owner for all purposes.

         This Warrant does not entitle any Holder hereof to any of the rights of
a shareholder of the Company including, without limitation, the right to vote or
to receive dividends or other distributions, and the Holder shall not be
entitled to receive any notice of any proceedings of the Company, except as
provided in the Warrant Agreement.

         This Warrant shall not be valid or obligatory for any purpose until it
shall have been countersigned by the Warrant Agent.

         Witness the facsimile seal of the Company and the facsimile signatures
of its duly authorized officers.

IN WITNESS WHEREOF, the undersigned has executed this certificate this ____ day
of ____________, 2005.

     Upon the terms and subject to the tender requirements of the Exchange Offer
(and if the Exchange Offer is extended, the terms of any such extension), and
effective upon the Expiration Date (as defined in the Prospectus), the
undersigned hereby tenders and surrenders without restriction to Rockwell all
right, title and interest in and to all of the Old Warrants that are being
tendered hereby and irrevocably constitutes and appoints American Stock Transfer

coupled with an interest), to (i) deliver and surrender certificates for such
Old Warrants or transfer ownership of such Old Warrants on the account books
maintained by the Book-Entry Transfer Facility, together, in any such case, with
all accompanying evidences of surrender, transfer and authenticity, to Rockwell,

     The undersigned hereby represents and warrants that the undersigned has

Warrants tendered hereby for exchange and that, the undersigned has good,
marketable and unencumbered title to such Old Warrants, free and clear of all

hereunder shall be binding upon the heirs, executors, administrators, personal

undersigned. This tender may be revoked prior to the Expiration Date.

     The undersigned understands that the valid tender of the Old Warrants
pursuant to any of the procedures described in the Prospectus and in the

extended, the terms or conditions of any such extension). The undersigned
recognizes that under certain circumstances set forth in the Prospectus,
Rockwell may not be required to accept for exchange any of the Old Warrants

                                  INSTRUCTIONS
    FORMING PART OF THE TERMS AND TENDER REQUIREMENTS OF THE EXCHANGE OFFER

     1. Guarantee of Signatures.  No signature guarantee is required on this
Letter of Transmittal (a) if this Letter of Transmittal is signed by the
registered holder(s) (which term, for purposes of this Section, includes any
participant in the Book-Entry Transfer Facility's systems whose name(s)
appear(s) on a security position listing as the owner(s) of the Old Warrants) of
Old Warrants tendered herewith, unless such registered holder(s) has completed
either the box entitled "Special Issuance Instructions" on the Letter of
Transmittal or (b) if such Shares are tendered for the account of a financial
institution (including most commercial banks, savings and loan associations and
brokerage houses) that is a participant in the Security Transfer Agents
Medallion Program or by any other "eligible guarantor institution," as such term
is defined in Rule 17Ad-15 under the Exchange Act (each, an "Eligible
Institution"). In all other cases, all signatures on this Letter of Transmittal
must be guaranteed by an Eligible Institution.

     2. Requirements of Tender.  This Letter of Transmittal is to be completed
by holders of Old Warrants if certificates for Old Warrants are to be forwarded
herewith or, unless an Agent's Message is utilized, if tenders are to be made by
book-entry transfer to an account maintained by the Transfer Agent at the
Book-Entry Transfer Facility. Certificates evidencing tendered Old Warrants, or
timely confirmation of a book-entry transfer of Old Warrants (a "Book-Entry
Confirmation") into the Transfer Agent's account at the Book-Entry Transfer
Facility, as well as this Letter of Transmittal (or a manually signed facsimile
hereof), properly completed and duly executed, with any required signature
guarantees, or an Agent's Message in connection with a book-entry transfer, and
any other documents required by this Letter of Transmittal, must be received by
the Transfer Agent at one of its addresses set forth herein prior to the
Expiration Date. Holders of Old Warrants whose certificates of Old Warrants are
not immediately available, or who cannot complete the procedure for delivery by
book-entry transfer described on page   of the Prospectus on a timely basis or
who cannot deliver all other required documents to the Transfer Agent prior to
the Expiration Date, may tender their Old Warrants by properly completing and
duly executing a Notice of Guaranteed Delivery pursuant to the guaranteed
delivery procedure described on page   of the Prospectus. Pursuant to such
procedure: (i) such tender must be made by or through an Eligible Institution;
(ii) a properly completed and duly executed Notice of Guaranteed Delivery,
substantially in the form made available by Rockwell, must be received by the
Transfer Agent prior to the Expiration Date and (iii) the certificates (or a
Book-Entry Confirmation) evidencing all tendered Old Warrants, in proper form
for transfer, in each case together with this Letter of Transmittal (or a
manually signed facsimile hereof), properly completed and duly executed, with
any required signature guarantees (or, in the case of a book-entry delivery, an
Agent's Message) and any other documents required by this Letter of Transmittal,
must be received by the Transfer Agent within three trading days after the date
of execution of such Notice of the Guaranteed Delivery. If Old Warrant
certificates are forwarded separately to the Transfer Agent, a properly
completed and duly executed Letter of Transmittal must accompany each such
delivery.

     The method of delivery of this Letter of Transmittal, Old Warrant
certificates and all other required documents, including delivery through the
Book-Entry Transfer Facility, is at the option and the risk of the tendering
holder and the delivery will be deemed made only when actually received by the
Transfer Agent (including, in the case of book-entry transfer, by Book-Entry
Confirmation). If delivery is by mail, registered mail with return receipt
requested, properly insured, is recommended. In all cases, sufficient time
should be allowed to ensure timely delivery.

     3. Inadequate Space.  If the space provided herein is inadequate, the Old
Warrant certificate numbers and/or the number of Old Warrants and any other
required information should be listed on a separate signed schedule attached
hereto.

     4. Partial Tenders (not applicable to holders of Old Warrants who tender by
book-entry transfer).  If fewer than all of the Old Warrants evidenced by any
Old Warrant certificate are to be tendered, fill in the number of Old Warrants
that are to be tendered in the box entitled "Number of Warrants Tendered." In
this case, New Warrant Certificates for the Old Warrants that were evidenced by
your Old Warrant certificates, but were not tendered by a holder, will be sent
to such holder, unless otherwise provided in the appropriate box on this Letter
of Transmittal, as soon as practicable after the Expiration Date. All Old
Warrants represented by certificates delivered to the Transfer Agent will be
deemed to have been tendered unless otherwise indicated.

     5. Signatures on Letter of Transmittal.  If this Letter of Transmittal is
signed by the registered holder(s) of the Old Warrants tendered hereby, the
signature(s) must correspond with the name(s) as written on the face of the
certificate(s) of Old Warrants without alteration, enlargement or any change
whatsoever.

     If any of the Old Warrants tendered hereby are held of record by two or
more joint owners, all such owners must sign this Letter of Transmittal.

     If any of the tendered Old Warrants are registered in different names on
several certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations.

     If this Letter of Transmittal or any Old Warrant certificates are signed by
a trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and proper evidence satisfactory to
Rockwell of the authority of such person so to act must be submitted.

     6. Transfer Taxes.  If surrendered Old Warrant certificates are registered
in the name of any person other than the person(s) signing this Letter of
Transmittal, the amount of any warrant transfer taxes (whether imposed on the
registered holder or such person) payable as a result of the transfer to such
person will be deducted from the payment for such securities if satisfactory
evidence of the payment of such taxes, or exemption therefrom, is not submitted.
Except as provided in this Instruction 6, it will not be necessary for transfer
tax stamps to be affixed to the certificates listed in this Letter of
Transmittal.

     7. Special Issuance and Delivery Instructions.  If a New Warrant
certificate is to be issued in the name of or delivered to, and, if appropriate,
Old Warrant certificates not tendered or not accepted for exchange are to be
issued or returned to, any person(s) other than the person(s) signing this
Letter of Transmittal or to an address other than that shown in this Letter of
Transmittal, the appropriate boxes on this Letter of Transmittal must be
completed.

     8. Substitute Form W-9:  A non-exempt warrant holder is required to provide
the Transfer Agent with such warrant holder's correct Taxpayer Identification
Number ("TIN") on the enclosed Substitute Form W-9 (described in the enclosed
Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9). If the certificate(s) are in more than one name or are not in the
name of the actual owner, consult the enclosed Substitute Form W-9 guidelines
for additional guidance on which number to report. The surrendering warrant
holder must check the box in Part 4 if a TIN has not been issued and the warrant
holder has applied for a number or intends to apply for a number in the near
future. Please review the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional details on what
Taxpayer Identification Number to give the Transfer Agent.

     9. Requests for Assistance or Additional Copies.  Questions and requests
for assistance or additional copies of the Prospectus, this Letter of
Transmittal, the Notice of Guaranteed Delivery or any other document enclosed,
may be directed to the Transfer Agent at the address and phone numbers set forth
above, or from brokers, dealers, commercial banks or trust companies.

     10. Lost, Destroyed or Stolen Certificates.  If any certificate
representing Old Warrants has been lost, destroyed or stolen, the holder should
promptly notify American Stock Transfer and Trust Company, in its capacity as
transfer agent for the Old Warrants (telephone number: (718) 921-8200 or (800)
937-5449). The holder will then be instructed as to the steps that must be taken
in order to replace the certificate. This Letter of Transmittal and related
documents cannot be processed until the procedures for replacing lost or
destroyed certificates have been followed.

     IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A MANUALLY SIGNED FACSIMILE
HEREOF) TOGETHER WITH ANY REQUIRED SIGNATURE GUARANTEES, OR, IN THE CASE OF A
BOOK-ENTRY TRANSFER, AN AGENT'S MESSAGE, AND ANY OTHER REQUIRED DOCUMENTS, MUST
BE RECEIVED BY THE TRANSFER AGENT PRIOR TO THE EXPIRATION DATE AND EITHER
CERTIFICATES FOR TENDERED SHARES MUST BE RECEIVED BY THE TRANSFER AGENT OR
WARRANTS MUST BE DELIVERED PURSUANT TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER,
IN EACH CASE PRIOR TO THE EXPIRATION DATE. DELIVERY OF DOCUMENTS TO THE
BOOK-ENTRY TRANSFER FACILITY WILL NOT CONSTITUTE DELIVERY TO THE TRANSFER AGENT.

PRIVACY ACT NOTICE. -- Section 6109 requires most recipients of dividend,
interest, or certain other income to give taxpayer identification numbers to
payers who must report the payments to the IRS. The IRS uses the numbers for
identification purposes and to help verify the accuracy of tax returns. The IRS
may also provide this information to the Department of Justice for civil and
criminal litigation and to cities, states and the District of Columbia to carry
out their tax laws. The IRS may also disclose this information to other
countries under a tax treaty, or to Federal and state agencies to enforce
Federal nontax criminal laws and to combat terrorism. Payers must be given the
numbers whether or not recipients are required to file tax returns. Payers must
generally withhold a portion of taxable interest, dividend, and certain other
payments to a payee who does not furnish a taxpayer identification number to a
payer. Certain penalties may also apply.
