D. The Parties wish to enter into this three-party assignment agreement, hereinafter referred to as the "Agreement", to confirm in writing the terms and conditions of the Assignment

HAVE AGREED AS FOLLOWS:

4. General Description and Workplace

1.1. Employer realizes the Assignment by temporarily assigning Employee to Milacron, effective as of the date stated below.

1.2. Employee will habitually perform the Assignment from the Employer's offices in the Netherlands, but the Assignment will also require regular travel (e.g. to Milacron in the United States of America). Travel time will not qualify as work time.

5. Position during the Assignment

2.1. Under the Assignment, Employee will carry out the position of Global President Cimcool for Milacron. In connection therewith, Employee undertakes to discharge all the duties assigned by law, Employer and Milacron (on behalf of Employer), in accordance with the rules, regulations and procedures laid down in law and Milacron/Employer policies, as well as the general rules, regulations and instructions that Employer and Milacron may adopt from time to time.

2.2. Employee reports his activities under the Assignment to the person so decided by Employer (further to indication by Milacron).

2.3. During and regardless of the Assignment, Employee will continue his role as Employer's Managing Director. Employee confirms that he is willing and able to accept additional workload resulting from the Assignment.

2

3

2.4. The Parties do not foresee an unreasonably high work pressure resulting from the Assignment. They anticipate that Employee performs his Managing Director activities for Employer and the Assignment during a full time work week of 40 hours, notwithstanding that reasonable overtime will be required from time to time considering the very senior level of the work activities concerned.

2.5. Employee covenants that he shall also perform duties other than those which are considered his usual duties, if such performance may be reasonably expected from him.

2.6. Employee remains an employee of Employer throughout the duration of the Assignment. During the Assignment the terms and conditions of employment between Employer and Employee continue, save and except as otherwise required by law, agreed to in this Agreement or agreed or otherwise to between Employer and Employee.

3.    Term and Termination

3.1. The Assignment is entered into for an initial temporary duration of 12 months. The Assignment will renew automatically thereafter for subsequent 12 month periods, save and except if the Assignment is terminated earlier. Upon termination of the Assignment and/or the Employment between Employer and Employee, this Agreement will automatically terminate.

3.2. The Assignment may be terminated by any of the Parties, upon providing 1 month's written notice to the other Parties.

3.3. In derogation of article 3.2 above, the Assignment may be terminated by Milacron and/or Employer with immediate effect in case of Employee's gross misconduct, violation of this Agreement or any other reason for immediate termination.

3.4. In any event, the Assignment will terminate with immediate effect on the date on which:

4

(a) Milacron informs Employer that they no longer wish to rely on Employee's services in the role of Global President Cimcool;

(b) the Employment between Employer and Employee ends.

4.    Consideration for Assignment

4.1. Employer will pay Employee an amount of EUR €2,500 (including 8% holiday allowance) gross per month, as consideration for the Assignment (and notwithstanding his regular wages under the Employment). After subtracting any required deductions or withholdings, the net amount will be paid into Employee's bank account as part of his monthly remuneration.

4.2. During the Assignment the Employee's bonus eligibility under his bonus program with Employer increases from a 40% to a 50% maximum of the combination of his base salary under the Employment Agreement and his consideration under this Assignment Agreement. The granting of a bonus (and the percentage thereof) will, at all times, remain at Employer's discretion. Employee can in no event lay claim to a bonus that has not yet been granted. The granting of a bonus in any given year or during several years will not create a precedent for any subsequent years. The tax and social security consequences of participation in a bonus program or the granting of a bonus will be at Employee's expense. If Employer grants a bonus, Employee will receive the gross bonus, less all deductions and withholdings required by law, on the condition that Employee is actively employed by Employer on the date of bonus payment and actively performing the Assignment.

4.3. Employee covenants that he will work overtime outside the normal working hours whenever a proper performance of his duties so requires. Remuneration for such overtime activities is factored into Employee's base salary and the additional consideration under article 4.1 above. No additional remuneration for overtime will be paid.

4.4. Payments made to Employee by Milacron under this Agreement, are payments made on behalf of Employer.

4

5.    Rechargeable rights

5.1. Employer will recharge to Cimcool Industrial Products LLC (or other intercompany entities as appropriate) the costs that they incur for the Assignment of Employee (including the consideration under article 4.1 above and the costs related to the increase of maximum bonus eligibility under article 4.2 above (the "Rechargeable Rights")).

5.2. The Rechargeable Rights incurred by Employer shall be accumulated and, to the extent that these Rechargeable Rights relate to the Assignment, be charged to Milacron in accordance with the arm's length principle. Employer will add a 5% mark-up to the Rechargeable Rights charged to Milacron.

5.3. When charging the Rechargeable Rights to Milacron, Employer shall compound the aggregate amount either during a financial year or during a shorter period, as Employer may deem appropriate.

5.4. After having determined the amount of the Rechargeable Rights, Employer, shall issue an appropriate invoice to Milacron with a reference to this Agreement and a description of the Rechargeable Rights that are recharged.

5.5. The maturity of the invoices shall be within (thirty) 30 days after the date of their issue. The payment of the invoices shall be made in Euros.

6.Full Time Commitment / Sidelines

7.4. Employee understands that, if he breaches this article or any other provision of this Agreement (including provisions that survive this Agreement), Milacron and/or Employer may sustain irreparable injury and may not have an adequate remedy at law.

transfers such Intellectual Property and Intellectual Property Rights to Employer, which transfer is hereby accepted by Employer.

ADDENDUM TO THE EMPLOYMENT AGREEMENT

THE UNDERSIGNED:

I. Cimcool Industrial Products B.V., a private limited liability company having its registered office and maintaining a place of business at Schiedamsedijk 20 in Vlaardingen, Netherlands (the 'Employer'), lawfully represented by its Supervisory Board Member, Mr. Ronald M. Krisanda;

AND

2. Gerrit Jue, residing in the Netherlands at 3961 AA Wijk bij Duurstede, at the Dijkstraat 10, (the 'Employee');

The Employer and Employee together are referred to as "the Parties".

WHEREAS:

a.) The Employee entered into an employment contract with the Employer on I September 2000. The Employee currently holds the position of Managing Director, or Director, for Milacron B.V. Milacron Nederland B.V., Cimcool Industrial Products 13.V., Cimcool Europe B.V. and its branches, and Cimcool Polska;

b.) Simultaneously with this Addendum, the Employee is entering into an amendment to his Employment Contract in which he will take the global role of President, Cimcool Industrial Products;

c.) Parties agreed upon a target pension scheme (in Dutch: streefregeling) by means of an Addendum to the employment contract dated June 24, 2004 and Pensioenbrief beschikbare premie dated June 6, 2004 (the 'Target Scheme'), which Target Scheme is executed by Avero Achmea;

d.) Given new Dutch fiscal regulations (in Dutch: Wet Witteveen) this Scheme is no longer fiscally compliant per December 31, 2014.

AGREE AS FOLLOWS:

6. Parties agree on the termination of the Employee's Target Scheme per September 30, 2016. Consequently the Target Scheme will be closed for any future pension accrual as per October 1, 2016.

7. Parties agree upon a new pension plan, i.e. a defined contribution plan (in Dutch: beschikbare premieregeling) per October 1, 2016 during continued employment with Employer as advised and introduced by Adviesgroep Combined. The costs of this new pension plan will be borne by the Employer. All rights and obligations with respect to the new pension plan are laid down in the defined contribution plan, as amended from time to time, a copy of which is attached as Appendix 1.

8. The Employer may amend the new pension plan— and, consequently, the pension agreement — without the Employee's consent if and insofar as it has a weighty interest in doing so that is of such a nature that the Employee's interests, insofar as they are harmed by the amendment, in all reasonableness and fairness must yield to the Employer's interest.

4. The Employer shall fulfill its pension obligations under the Target Scheme on the grounds of the Dutch Pension Act ("Pensioenwet"). This includes payment of assumed 'back services' in relation to the closed Target Scheme related to the period 13 August 2003 till September 30, 2016 in the amount of EUR 308,009.31 gross (Appendix 2). Parties envisage to have payment of the assumed 'backservice' of EUR 308,009.31 gross into the closed Target Scheme or any other pension plan. If such payment into the Target Scheme or any other pension plan will not be tax facilitated under the current Dutch tax regulations, this (remaining) gross amount will be paid in cash to the Employee after withholding all necessary taxes and social security premiums. For administrative reasons, the parties envisage to have this matter settled by October 31, 2016 at the latest.

1. Parties agree upon a final discharge clause stipulating that the Employer (and its affiliates) and the Employee will have no further obligations to each other on the basis of the (closed) Target Scheme and the Parties will grant each other full and final discharge in this respect.

6. This Addendum constitutes the entire agreement and understanding between the Parties with respect to its subject matter and replaces and supersedes all prior agreements, arrangements, undertakings or statements regarding such subject matter.

2. This Addendum shall be governed by and construed in accordance with the laws of the Netherlands.

Thus agreed upon and executed in duplicate. Cimcool Industrial Products B.V.
