GmbH and Milacron B.V., the lending institutions
from time to time party thereto (individually,

New York, New York 10006
Attention: Maria Pina

Ladies and Gentlemen:

     Milacron will on the date of this letter agreement (this "Letter Agreement") sign a definitive agreement with respect to the sale of the metalcutting tools business (other than the round tools business) organized within or owned or operated by Valenite Inc. (the business to be sold pursuant to such sale, the "Valenite Business"). The sale of the Valenite Business, which will be effected through a sale of all the outstanding capital stock of Valenite Inc. (and, possibly, the separate sale of the outstanding capital stock of certain foreign subsidiaries of Valenite Inc. as provided in the Stock Purchase Agreement (as defined below)), is hereinafter referred to as the "Valenite Transaction". Capitalized terms used and not otherwise defined in this Letter Agreement shall have the meanings assigned to them in the Credit Agreement or in the Letter Agreement dated as of May 3, 2002 (the "Widia Letter Agreement") among Milacron, Milacron Kunststoffmaschinen Europa GmbH, Milacron Metalworking Technologies Holding GmbH and Milacron B.V., the Lenders (as defined therein), Deutsche Bank Trust Company Americas, as Agent, and PNC Bank, as documentation agent.

     As the subsidiaries of Milacron currently conducting the Valenite Business also conduct other businesses and are not all owned by Valenite Inc., Milacron currently intends to prepare for the Valenite Transaction by isolating the Valenite Business in certain wholly-owned subsidiaries through certain intercompany share and asset transfers (all such transfers, as specifically described in Annex A hereto, the "Intercompany Transfers"). Milacron will take all steps necessary or desirable, in the reasonable judgment of the Agent, to ensure that the Intercompany Transfers related to the Valenite Transaction will not adversely affect, in the reasonable judgment of the Agent, in any respect the validity, priority or perfection of the Agent's security interest for its benefit and the benefit of the Lenders in any Collateral; provided that the security interest in the Collateral sold (or owned by a Subsidiary of Milacron all of the issued and outstanding capital stock of which that is held by Milacron or its Subsidiaries is sold) pursuant to the Valenite Transaction will be released at the time of the initial closing of the Valenite Transaction against simultaneous payment of $100.0 million of the Permanent Reduction Amount (as defined below).

     Unless otherwise agreed to by the Requisite Lenders, Milacron will or will cause its Subsidiaries to), (1) permanently reduce the Total revolving Loan Commitment, simultaneously with the initial closing of the Valenite Transaction, in an amount equal to $100.0 million, (2) permanently reduce the Total Revolving Loan Commitment, within two Business Days after the initial closing of the Valenite Transaction, in an amount equal to 50% of the amount equal to the positive difference (if any) between (i) the amount of the Net Cash Proceeds of the Valenite Transaction (minus, without duplication of any other deductions made in determining such Net Cash Proceeds, an amount equal to the sum of the Bond Amount (as defined below) and the Receivables Amount (as defined below)) and (ii) $125.0 million (the sum of the amounts specified in clauses (1) and (2) of this sentence being hereinafter referred to as the "Permanent Reduction Amount") and (3) prepay Revolving Loans, within two Business Days after the initial closing of the Valenite Transaction, in an aggregate principal amount equal to the portion of the $21.0 million in estimated 2002 tax related to the Valenite Transaction that reduces the Net Cash Proceeds of the Valenite Transaction but is not payable on or before the first Business Day after the initial closing of the Valenite Transaction (such portion, as certified by Milacron in a written notice delivered to the Agent within two Business Days after the initial closing of the Valenite Transaction, being referred to as the "Valenite Tax Reduction Amount"). Milacron agrees that, if the amount referred to in clause (2) of the immediately preceding sentence increases at any time after the date of the initial commitment reduction pursuant to the immediately preceding sentence, then Milacron will effect a further permanent reduction of the Total Revolving Loan Commitment in accordance with the immediately preceding sentence to reflect such increase within two Business Days after such increase. Unless otherwise agreed to by the Requisite Lenders, after the date that is two Business Days after the initial closing of the Valenite Transaction, the sum of (i) the aggregate principal amount of Revolving Loans outstanding at any time plus (ii) the Letters of Credit Usage at such time (the sum of the amounts described in preceding clauses (i) and (ii) being hereinafter referred to as the "Total Exposure") shall not exceed the Total Revolving Loan Commitment at such time minus the Valenite Tax Reduction Amount (and the sum of the aggregate principal amount of Revolving Loans of any Lender at any time plus such Lender's Pro Rata Share of the Letters of Credit Usage at such time shall not exceed such Lender's Pro Rata Share of (a) the Total Revolving Loan Commitment at such time minus (b) the Valenite Tax Reduction Amount), except to the extent resulting from Revolving Loans made to fund the payment of taxes by Milacron or one of its Subsidiaries in an aggregate amount equal to the Delayed Valenite Tax Amount (as defined below). On June 30, 2003, (a) Milacron will (or will cause its Subsidiaries to) permanently reduce the Total Revolving Loan Commitment by an amount equal to the difference between the Valenite Tax Reduction Amount and the Delayed Valenite Tax Amount on such date and (b) automatically upon such permanent reduction, the Valenite Tax Reduction Amount will be reduced to the Delayed Valenite Tax Amount on such date. On any date prior to June 30, 2003, if Milacron permanently reduces the Total Revolving Loan Commitment (other than to satisfy a requirement in the Credit Agreement, the Widia Letter Agreement or this Letter Agreement to reduce the Total Revolving Loan Commitment), then automatically upon such permanent reduction, the Valenite Tax Reduction Amount will be reduced (but not below the greater of zero and the Delayed Valenite Tax Amount) in the amount of such permanent reduction (the aggregate amount of reductions in the Valenite Tax Reduction Amount pursuant to this sentence being referred to as the "Reduction Amount Adjustment"). The five immediately preceding sentences shall not modify any other reduction of the Total Revolving Loan Commitment required pursuant to the terms of the Credit Agreement; provided that (a) no reduction of the Total Revolving Loan Commitment pursuant to Section 3.3(d) of the Credit Agreement shall be required in respect of the Net Cash Proceeds of the Valenite Transaction except as provided in the five immediately preceding sentences and (b) each reduction of the Total Revolving Loan Commitment pursuant to the first, second, fourth and fifth sentences of this paragraph will be included for purposes of determining the amounts of scheduled reductions of the Total Revolving Loan Commitment required by the fourth sentence of Section 2.1(a) of the Credit Agreement. For purposes of this paragraph, (a) the term "Bond Amount" shall mean the aggregate amount, not to exceed the aggregate principal amount of the Redeemed Bonds (as defined below) plus accrued but unpaid interest thereon to the date of redemption thereof, of cash deposited (or used to acquire investments that are deposited) by Milacron or any of its Subsidiaries to effect on or prior to 60 days after the initial closing of the Valenite Transaction the redemption of the industrial revenue and municipal bonds (the "Redeemed Bonds") listed on Exhibit B hereto (any such deposit, the "Redeemed Bonds Deposit"), as required by any contract binding on Milacron or its Subsidiaries, (b) the term "Receivables Amount" shall mean the aggregate amount of cash applied on or prior to the date on which the Purchase Price adjustment is made pursuant to the Stock Purchase Agreement by Milacron or any of its Subsidiaries to repurchase receivables and associated assets related to the Valenite Business that were sold pursuant to the Receivables Purchase Agreement or pursuant to the receivables program of Valenite-Widia Japan Inc., as required by any contract binding on Milacron or its Subsidiaries and (c) the term "Delayed Valenite Tax Amount" shall mean the aggregate amount (not to exceed $21.0 million minus the sum of the Initial Valenite Tax Amount (as defined below) and the Reduction Amount Adjustment), determined in good faith by Milacron, of Federal, state and local income or other tax (excluding the portion of such tax payable on or before the first Business Day after the initial closing of the Valenite Transaction (such portion being referred to as the "Initial Valenite Tax Amount")) that is (i) payable on or before June 30, 2003, by Milacron or any of its Subsidiaries with respect to the tax year ending on or about December 31, 2002 and (ii) is payable by reason of the Valenite Transaction (such non-excluded tax, the "Covered Tax"), as certified by Milacron in a written notice delivered to the Agent not more than three Business Days prior to the date on which Milacron or one of its Subsidiaries will pay such tax. The Delayed Valenite Tax Amount will be increased (but not to an amount in excess of $21.0 million minus the sum of the Initial Valenite Tax Amount and the Reduction Amount Adjustment), at any time from time to time on or prior to June 30, 2002, to reflect any increase in the aggregate amount, determined in good faith by Milacron, of Covered Tax, as certified by Milacron in a written notice delivered to the Agent not more than three Business Days prior to the date on which Milacron or one of its Subsidiaries will pay such increase in Covered Tax.

     The Valenite Transaction will be effected pursuant to the Stock Purchase Agreement to be entered into between Milacron and the proposed purchaser of the Valenite Business (the "Purchaser"), which will (a) require the payment of the purchase price for the Valenite Business (the "Purchase Price") entirely in cash and contemplate that certain indebtedness of the Valenite Business might be retained by certain subsidiaries to be sold pursuant to the Valenite Transaction (in which case the Purchase Price would be adjusted as described in clause (b) below), (b) provide for an adjustment of the Purchase Price based on changes in the net assets of the Valenite Business as specified in the Stock Purchase Agreement (assuming no indebtedness as of the reference date specified in the Stock Purchase Agreement, with any payment required to be made by or to Milacron to reflect that adjustment to be made after the closing of the Valenite Transaction), (c) contemplate the possibility of the survival after the closing of the Valenite Transaction of certain guarantees issued by, and certain other obligations incurred by, Milacron and certain of its subsidiaries that will not be sold pursuant to the Valenite Transaction that relate to the Valenite Business (to the extent that, notwithstanding the Purchaser's obligation to use reasonable best efforts to do so, the Purchaser is unable to replace such guarantees or terminate the transactions or programs supported by such other obligations or otherwise replace the obligors thereon), provided that the Purchaser will be required to indemnify Milacron and such subsidiaries for all claims and expenses related to such guarantees and other obligations, and (d) contemplate the possibility of the survival after the closing of the Valenite transaction of intercompany receivables and payables created in the ordinary course of business, in each case between the Valenite Business, on the one hand, and Milacron and its Subsidiaries (excluding the Valenite Business), on the other hand, provided that all such intercompany receivables and payables will be required to be settled no later than the date on which the settlement of the Purchase Price adjustment is made.

     Pursuant to Section 11.2 of the Credit Agreement, each of the Lenders and the Agent hereby: (1) consents under the Credit Agreement to (a) the execution and delivery by Milacron of a stock purchase agreement to be dated the date of this Letter Agreement with respect to the Valenite Transaction (the "Stock Purchase Agreement"), which will be in the form of the draft thereof attached hereto as Exhibit A (with modifications thereto made by Milacron and reasonably acceptable to the Agent), (b) the consummation of the Valenite Transaction, the other transactions specifically described in the Stock Purchase Agreement and the Redeemed Bonds Deposit; provided that the Valenite Transaction is consummated on or prior to December 31, 2002, in accordance with the terms of the Stock Purchase Agreement and with no waiver, amendment, forbearance or other modification of the terms and conditions of the Stock Purchase Agreement as in effect on the date hereof (other than any such waiver, amendment, forbearance or other modification that is acceptable to the Agent), (c) the release of all security interests granted pursuant to the Security Documents in all Collateral sold (or owned by any subsidiary of Milacron all of the issued and outstanding capital stock of which that is owned by Milacron or its Subsidiaries is sold) pursuant to the Valenite Transaction at the time of sale against simultaneous payment of $100.0 million of the Permanent Reduction Amount, and (d) the Intercompany Transfers; provided that the Intercompany Transfers will not adversely affect, in the reasonable judgment of the Agent, in any respect the validity, priority or perfection of the Agent's security interest for its benefit and for the benefit of the Lenders in any Collateral; provided further that the security interest in the Collateral sold (or owned by any Subsidiary of Milacron all of the issued and outstanding stock of which that is owned by Milacron or its Subsidiaries is sold) pursuant to the Valenite Transaction will be released at the time of the initial closing of the Valenite Transaction against simultaneous payment of $100.0 million of the Permanent Reduction Amount, (2) authorizes and directs Deutsche Bank Trust Company Americas, as Agent, to take such actions as are necessary or appropriate, in its reasonable judgment, under the Security Documents in connection with the events set forth in clause (1) above (and consents to such actions), and (3) agrees that automatically upon the initial closing of the Valenite Transaction and the fulfillment of the requirements set forth in the first sentence of the third paragraph of this Letter Agreement in connection with the receipt by Milacron or any of its Subsidiaries of Net Cash Proceeds from the Valenite Transaction, the Credit Agreement will, provided that no Default or Event of Default shall have occurred and be continuing immediately prior to and after consummation of the Valenite Transaction and performance by Milacron of its obligations hereunder (other than any Default or Event of Default that would arise under Section 6.13 or 6.15 of the Credit Agreement as a result of the Valenite Transaction but will not arise if the amendments set forth in clauses (i)(a) and (b) below or (ii)(b)(x) and (y) below, as applicable, become effective), be amended as provided below:
