                    AND THE MILACRON RETIREMENT SAVINGS PLAN

         Record Date to receive the attached 401(k) Plan Participant Election
         Form, a copy of the Prospectus and other related materials. The 401(k)

         have been allocated to your 401(k) plan account.

Q-2:     WHO WILL DECIDE WHETHER OR NOT TO EXERCISE THE RIGHTS TO ACQUIRE
         ADDITIONAL SHARES OF COMMON STOCK FOR MY ACCOUNT UNDER THE 401(K) PLAN?

A-2:     As a participant in the 401(k) plan, you will be able to direct the
         Trustee to exercise some or all of the Rights that have been allocated
         to your 401(k) account to purchase additional shares of our common

Q-4:     WILL THE 401(K) PLAN'S NEW 25% LIMITATIONS ON THE COMPANY STOCK FUND

         SHARES OF COMMON STOCK THAT I WANT TO PURCHASE IN THE RIGHTS OFFERING
         UNDER THE RIGHTS THAT HAVE BEEN ALLOCATED TO MY ACCOUNT?

         the Rights Offering on your behalf.

Q-11:    WHEN IS THE ABSOLUTE LAST DATE BY WHICH I MUST DELIVER MY COMPLETED
         INSTRUCTIONS TO THE TRUSTEE SO THAT I CAN BE ASSURED THAT I WILL BE
         ABLE TO ACQUIRE THE SHARES OF COMMON STOCK I WANT TO PURCHASE FOR MY
         401(K) ACCOUNT?

A-11:    In order to give the Trustee the time it needs to complete the
         necessary paperwork so that it may exercise your Rights before the
         Rights Offering terminates, your completed documents must be received
         by the Trustee at or prior to 5:00 p.m., New York City time, five
         business days before the expiration date of the Rights Offering (     ,
         2004, assuming the expiration date is not extended by the Company). If
         you are sending your completed instructions to the Trustee by mail,
         please allow sufficient time for mail delays.

Q-12:    WHEN IS THE ABSOLUTE LAST DATE BY WHICH I MUST ALLOCATE FUNDS TO THE
         PUTNAM MONEY MARKET FUND IN ORDER TO ACQUIRE THE SHARES OF COMMON STOCK
         I WANT TO PURCHASE PURSUANT TO THE RIGHTS THAT HAVE BEEN ALLOCATED TO
         MY 401(K) ACCOUNT?

A-12:    If you elect to exercise some or all of your Rights, you must have
         sufficient funds in the Putnam Money Market Fund (an existing
         investment fund under the 401(k) plan) at or prior to 5:00 p.m., New
         York City time, five business days before the expiration date of the
         Rights Offering(    ,2004, assuming the expiration date is not extended
         by the Company) in order to satisfy the subscription price payable by
         you upon exercise of your Rights. One business day before the
         expiration date of the Rights Offering, the Trustee will transfer these
         funds from your Putnam Money Market Fund account and use such funds to
         participate on your behalf in the Rights Offering.

Q-13:    WHAT IF I DO NOT HAVE SUFFICIENT FUNDS IN MY PUTNAM MONEY MARKET FUND
         ACCOUNT?

A-13:    If you transfer insufficient funds into, or you transfer amounts out
         of, the Putnam Money Market Fund, including after the fifth business
         day before the expiration date of the Rights Offering (due to, for
         example, a fund transfer, loan, withdrawal or distribution) and
         therefore you do not have sufficient funds to exercise all of your
         Rights in accordance with your election, the Rights will be exercised
         to the maximum extent possible with the amount you have invested in
         your Putnam Money Market Fund account.

Q-14:    WHAT IF THE PER SHARE PUBLIC TRADING MARKET PRICE OF THE COMPANY'S
         COMMON STOCK DECLINES AFTER I SUBMIT MY 401(K) PLAN PARTICIPANT
         ELECTION FORM TO THE TRUSTEE AND BEFORE THE TIME THAT THE TRUSTEE
         EXERCISES THE RIGHTS AND PURCHASES COMMON STOCK ON MY BEHALF?

A-14:    Once you send to the Trustee the 401(k) Plan Participant Election Form,
         you may not revoke your exercise instructions, unless the Company
         subsequently materially amends the terms of the Rights Offering. If you
         elect to exercise your Rights, you should be aware that the market
         value of the Company's common stock may go up or down after you submit
         your 401(k) Plan Participant Election Form to the Trustee and before
         the time that common stock is purchased pursuant to the Rights and
         allocated to your account under the 401(k) plan. See the section of the
         Prospectus captioned "Risk factors - Risks Relating to the Rights
         Offering - Once you exercise your rights, you may not revoke your
         exercise."



                                       5






Q-15:    WILL ANY COMMISSIONS OR FEES BE CHARGED TO MY ACCOUNT UNDER THE 401(K)
         PLAN?

A-15:    No.  No commissions or fees will be charged on the exercise of Rights
         by the 401(k) plan to purchase the common stock under the Rights
         Offering. Accordingly, no commissions or fees will be charged to your
         account.  If any administrative fees are charged, the Company will pay
         those fees.

Q-16:    WHEN WILL THE COMMON STOCK BE ISSUED AND ALLOCATED TO MY ACCOUNT UNDER
         THE 401(K) PLAN?

A-16:    As soon as administratively practicable after completion of the Rights
         Offering.  See Q&A 18 for further details.

Q-17:    WHEN CAN I TRANSFER OR SELL THE COMMON STOCK ALLOCATED TO MY ACCOUNT
         UNDER THE 401(K) PLAN?

A-17:    Shares purchased through the Rights Offering are available for transfer
         after allocation to your Company Stock Fund account. The shares will be
         allocated on the date of receipt by the Trustee of the shares. See Q&A
         18 for further details.

Q-18:    WILL THE NORMAL TIME PERIODS FOR THE PURCHASE AND SALE OF COMMON STOCK
         IN THE COMPANY STOCK FUND APPLY TO THE RIGHTS OFFERING UNDER THE 401(K)
         PLAN?

A-18:    No. It may take up to 10 business days (or longer) for the Trustee to
         receive the shares of common stock purchased pursuant to the Rights
         Offering. As a result, you temporarily will be unable to direct or
         diversify the common stock purchased for your individual account
         pursuant to the Rights Offering until such stock is received by the
         Trustee and allocated to your account. This temporary period, during
         which you will be unable to sell such common stock, is called a
         "blackout period." Whether or not you are planning retirement in the
         near future, we encourage you to carefully consider how this blackout
         period may affect your retirement planning, as well as your overall
         financial plan.

         This blackout period for the 401(k) plan is expected to begin on     ,
         2004 and end up to 10 business days later (or longer). During this
         time, you can determine whether the blackout period has started or
         ended by contacting Putnam at 1-800-873-0383 or by checking your
         account at its website at www.ibenefitcenter.com.

         It is very important that you review and consider the appropriateness
         of your current investments in light of your inability to direct or
         diversify during the blackout period the common stock purchased
         pursuant to the Rights Offering. For your long-term retirement
         security, you should give careful consideration to the importance of a
         well-balanced and diversified investment portfolio, taking into account
         all your assets, income and investments. You should be aware that there
         is a risk to holding substantial portions of your assets in the
         securities of any one company, as individual securities tend to have
         wider price swings, up and down, in short periods of time, than
         investments in diversified funds. If Milacron common stock has wide
         price swings during the blackout period, you might have a large loss
         and you would not be able to direct the sale of such common stock
         purchased pursuant to the Rights Offering during the blackout period.

         Avenue, Cincinnati, Ohio 45206, (513) 487-5612.

Q-19:    WILL PUTNAM NOTIFY ME WHEN THE SHARES ARE RECEIVED BY THE TRUSTEE AND
         ALLOCATED TO MY ACCOUNT?

A-19:    Yes.  Putnam will send a confirmation letter, via first class mail,
         to your last known address, after receipt by the Trustee of the shares
         and allocation of such shares to your account.  Also, you can contact
         Putnam at 1-800-873-0383 or check your account at its website at
         www.ibenefitcenter.com.

Q-20:    WILL THE RIGHTS OFFERING AFFECT THE NORMAL TIME PERIODS FOR THE
         PURCHASE AND SALE OF COMMON STOCK FOR MY 401(K) ACCOUNT?

A-20:    No. Your ability to purchase and sell shares of common stock (other
         than the common stock purchased pursuant to the Rights Offering) for
         your 401(k) account are subject to the normal time periods under the
         401(k) plan. The Rights Offering or blackout period will not affect
         your ability to sell common stock already allocated to your account or
         otherwise purchase common stock for your account (other than the common
         stock purchased pursuant to the Rights Offering).
