Notwithstanding any other provision of the Plan, the Committee may, with the approval of the Board of Directors of MacDermid, Incorporated, limit the employees eligible to participate in the Plan so as to effect this purpose.

5.2. Plan Unfunded. The Plan shall be unfunded and no assets shall be set aside for the payment of benefits under the Plan. All benefits shall be paid from the general assets of the Company, which remain subject to the claims of the general creditors of the company and may be used by the Company for any corporate purpose until benefit payments are made.

5.3. Unsecured Creditor. The rights of each Participant and his or her Beneficiary to benefits under the Plan shall be solely those of an unsecured creditor of the Company.

5.4. Amendment and Termination. The Board of Directors of MacDermid, Incorporated may at any time amend or terminate the Plan by action of the Board and execution of a written instrument by an authorized officer of the Company. However, no amendment to the Plan shall have any right to reduce or modify any benefit which has become nonforfeitable without the written consent of the Participant, or in the event of the Participant’s death, the Participant’s Beneficiary, except to the extent necessary, in the good faith judgment of the Committee, to comply with the provisions of section 409A of the Code.

5.5. Assignment of Benefits. No Participant or Beneficiary under the Plan shall have any right to assign, transfer, pledge or otherwise encumber the right to receive any benefit under the Plan, and any attempted assignment, transfer, pledge or other encumbrance shall be void and have no effect.

5.6. Employment Not Guaranteed. Participation in the Plan shall not be deemed to be consideration for, or an inducement to, or a condition of employment of any employee. Nothing contained in the Plan shall be deemed to give any Participant the right to be retained in the employment of the Company, nor shall any Participant or Beneficiary or any other person have any right to any payment, except as such payment may be provided under the terms of the Plan.

5.7. Binding Agreement. The provisions of this Plan shall be binding upon each Participant and the Company and their successors, assigns, heirs, executors and beneficiaries.

5.8. Withholding. The Company shall be entitled to deduct from all benefit payments made to a Participant or Beneficiary all applicable federal, state or local taxes required by law to be withheld from such payments.

5.10. Severability. The invalidity of any portion of the Plan shall not invalidate the remainder, and the remainder shall continue in full force and effect.

5.11. Construction. The Plan shall be construed in accordance with the laws of the State of Connecticut, except to the extent preempted by federal law, and in accordance with the provisions of section 409A of the Code, it being the intent of the Company and the Participants that the Plan and all amounts payable to the Participants under the Plan shall meet the requirements of section 409A of the Code to the extent applicable to the Plan and such payments. Recognizing such intent and the lack of guidance currently available under section 409A, each provision of the Plan shall be construed in such manner as shall be necessary to comply with such requirements.

Executed this 25^th day of February, 2005.
