                             SHARES OF COMMON STOCK
                      OFFERED PURSUANT TO RIGHTS GRANTED TO
                         RECORDHOLDERS OF MILACRON INC.

Dear Stockholder:

         This letter is being distributed by Milacron Inc. (the "Company") to
holders of record ("Recordholders") of shares of its common stock (other than
any common stock received upon conversion of the Company's 6.0% Series B
Convertible Preferred Stock), as of 5:00 p.m., New York City time, on
            , 2004 (the "Record Date"), whose addresses are outside the United
States and Canada or who have an APO or FPO address, in connection with a
rights offering (the "Rights Offering") of nontransferable subscription rights
(the "Rights") to subscribe for and purchase shares of the Company's common
stock. The Rights are described in the Company's prospectus dated          ,
2004 (the "Prospectus").

      The Rights will expire at 5:00 p.m., New York City time, on           ,
2004, subject to extension at the Company's discretion (the "Expiration Date").
The Rights Offering will not be extended to a date beyond           , 2004. As
described in the accompanying Prospectus, you are being granted 0.452 Rights for
each share of the Company's common stock owned of record as of 5:00 p.m., New
York City time, on the Record Date. The number of rights granted to each
Recordholder will be rounded up to the nearest whole number. Each Right will
allow you to purchase one share of common stock (the "Subscription Privilege")
at the cash price of $2.00 per share (the "Subscription Price"). You may
exercise all or a portion of the Rights granted to you.

         The Rights will be exercisable pursuant to subscription certificates
(the "Subscription Certificates"). A Subscription Certificate will not be mailed
to you, but will be held by the subscription agent for your account. To exercise
Rights, you must send a letter of instruction indicating the number of Rights
that you elect to exercise, together with payment of the Subscription Price in
full for each share of common stock subscribed for pursuant to the Subscription
Privilege, to the subscription agent. The number of Rights to which you are
entitled can be determined by multiplying 0.452 by the number of shares of the
Company's common stock that you owned of record as of 5:00 p.m., New York City
time, on the Record Date, and rounding the product up to the nearest whole
number. If you have any questions regarding the number of Rights to which you
are entitled, feel free to contact Innisfree M&A Incorporated at one of the
numbers listed below. To calculate the Subscription Price, multiply the number
of Rights you elect to exercise by $2.00. Payment may be made only in U.S.
dollars by check or bank draft drawn upon a U.S. bank, or postal, telegraphic
or express money order, payable to "Mellon Investor Services LLC." The
subscription agent must receive your letter of instruction with payment of the
Subscription Price, including final clearance of any checks, at or prior to
5:00 p.m., New York City time, on the Expiration Date. Uncertified personal
checks used to pay the Subscription Price must be received by the subscription
agent at least five days before the Expiration Date to allow sufficient time
for the check to clear. Accordingly, Rights holders who wish to pay the
Subscription Price by means of uncertified personal check are urged to
consider, in the alternative, payment by means of certified check, bank draft
or money order. FAILURE TO SEND A LETTER OF INSTRUCTION WITH THE CORRECT
PAYMENT TO THE SUBSCRIPTION AGENT WILL RESULT IN YOUR NOT BEING ABLE TO
EXERCISE YOUR RIGHTS. A Rights holder cannot revoke the exercise of its Rights.
Rights not exercised prior to the Expiration Date will expire.

         Your letter of instruction and payment of the Subscription Price must
be delivered to the subscription agent at one of the following addresses:
