EXECUTION COPY

FOURTH AMENDMENT dated as of May 18, 2012 (this “Amendment”), to the CREDIT AGREEMENT dated as of April 12, 2007 (as amended by that certain First Amendment, dated as of October 24, 2007, that certain Consent, Waiver and Amendment, dated as of July 28, 2008 and that certain Third Consent, Waiver and Amendment, dated as of November 29, 2011, and as otherwise amended, restated, supplemented, waived or otherwise modified prior to the date hereof, the “Credit Agreement”), among, inter alia, MACDERMID HOLDINGS, LLC, a Delaware limited liability company (“Holdings”), MATRIX ACQUISITION CORP., a Connecticut corporation, and MACDERMID, INCORPORATED, a Connecticut corporation (as successor to Matrix Acquisition Corp., the “Borrower”), the subsidiaries of the Borrower from time to time parties thereto, the LENDERS from time to time parties thereto, CREDIT SUISSE AG, as Administrative Agent and as Collateral Agent, and the other agents party thereto.

A. The Borrower has requested that the Credit Agreement be amended to, among other things, provide for the replacement of the existing Revolving Credit Facility with a new revolving credit facility (the “New Revolving Credit Facility”) in an aggregate principal amount of up to $50,000,000, the proceeds of which will be used by the Borrower for general corporate purposes. Except as otherwise provided herein, the New Revolving Credit Facility will have the same terms as the existing Revolving Credit Facility currently outstanding under the Credit Agreement. All Letters of Credit outstanding immediately prior to the Fourth Amendment Effective Date shall be deemed to be outstanding under the New Revolving Credit Facility.

B. Each existing Lender or other Person (each a “New Revolving Credit Lender”) that executes and delivers this Amendment and indicates a new revolving credit commitment on the lender consent form attached hereto as Annex I (the “Lender Consent”) will be deemed upon the Fourth Amendment Effective Date to have agreed to the terms of this Amendment and to have made a new revolving credit commitment in an aggregate principal amount as set forth on its Lender Consent (or such lesser amount as is allocated to it by Credit Suisse Securities (USA) LLC, as arranger of this Amendment) (a “New Revolving Credit Commitment”). Each existing Lender that executes and delivers this Amendment in its capacity as an existing Lender but does not indicate a New Revolving Credit Commitment on its Lender Consent shall be deemed to have agreed to this Amendment, but will not be deemed by virtue of such execution and delivery to have made any New Revolving Credit Commitment.

C. The existing Lenders who have executed and delivered the Lender Consent, constituting at least the Required Lenders, are willing to amend the Credit Agreement and the New Revolving Credit Lenders are willing to make New Revolving Credit Commitments as contemplated hereby, in each case on the terms and subject to the conditions set forth in this Amendment.

D. Capitalized terms used but not defined herein shall have the meanings assigned to such terms in the Credit Agreement.

(i) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Required Lenders and in Section 11.01.

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VII or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 11.08 shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Issuing Bank hereunder; third, to cash collateralize the Issuing Bank’s Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.15(d); fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement and (y) cash collateralize the Issuing Banks’ future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 2.15(d); sixth, to the payment of any amounts owing to the Lenders or the Issuing Banks as a result of any judgment of a court of competent jurisdiction obtained by any Lender or the Issuing Bank against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or L/C Borrowing in respect of which such Defaulting Lender has not fully funded its appropriate

share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 5.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and L/C Borrowings owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or L/C Borrowings owed to, such Defaulting Lender until such time as all Loans and L/C Exposure are held by the Lenders pro rata in accordance with the Commitments under the applicable Facility without giving effect to Section 2.15(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post cash collateral pursuant to this Section 2.15(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees. (A) No Defaulting Lender shall be entitled to receive any Commitment Fee for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(B) Each Defaulting Lender shall be entitled to receive Letter of Credit Fees for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Pro Rata Share of the stated amount of Letters of Credit for which it has provided cash collateral pursuant to Section 2.15(d).

(C) With respect to any Letter of Credit Fees not required to be paid to any Defaulting Lender pursuant to clause (B) above, the Borrower shall (x) pay to each non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s obligation to fund participations in respect of Letters of Credit that have been reallocated to such non-Defaulting Lender pursuant to clause (iv) below, (y) pay to each Issuing Bank the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such Issuing Bank’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(iv) Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s obligation to fund participations in respect of Letters of Credit shall be reallocated among the non-Defaulting Lenders in accordance with their respective Pro Rata Shares (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (x) the conditions set forth in Section 5.02 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the aggregate Revolving Credit Exposure of any non-Defaulting Lender to exceed such non-Defaulting Lender’s Revolving Credit Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a non-Defaulting Lender as a result of such non-Defaulting Lender’s increased exposure following such reallocation.

(v) Cash Collateral. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, cash collateralize any Issuing Bank’s Fronting Exposure in accordance with the procedures set forth in Section 2.15(d).

(b) Defaulting Lender Cure. If the Borrower, the Administrative Agent and each Issuing Bank agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any cash collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit to be held pro rata by the Lenders

in accordance with the Commitments under the applicable Facility (without giving effect to Section 2.15(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

(c) New Letters of Credit. So long as any Lender is a Defaulting Lender, no Issuing Bank shall be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

(d) Cash Collateral. (i) At any time that there shall exist a Defaulting Lender, within one Business Day following the written request of the Administrative Agent or any Issuing Bank (with a copy to the Administrative Agent) the Borrower shall cash collateralize such Issuing Bank’s Fronting Exposure with respect to such Defaulting Lender (determined after giving effect to Section 2.15(a)(iv) and any cash collateral provided by such Defaulting Lender) in an amount not less than the Minimum Collateral Amount.

(ii) The Borrower, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to the Administrative Agent, for the benefit of each Issuing Bank, and agrees to maintain, a first priority security interest in all such cash collateral as security for the Defaulting Lender’s obligation to fund participations in respect of Letters of Credit, to be applied pursuant to clause (iii) below. If at any time the Administrative Agent determines that cash collateral is subject to any right or claim of any Person other than the Administrative Agent and such Issuing Bank as herein provided (other than Permitted Liens), or that the total amount of such cash collateral is less than the Minimum Collateral Amount, the Borrower will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional cash collateral in an amount sufficient to eliminate such deficiency (after giving effect to any cash collateral provided by the Defaulting Lender.

(iii) Notwithstanding anything to the contrary contained in this Agreement, cash collateral provided under this Section 2.15 in respect of Letters of Credit shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of Letters of Credit (including, as to cash collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the cash collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iv) Cash collateral (or the appropriate portion thereof) provided to reduce any Issuing Bank’s Fronting Exposure shall no longer be required to be held as cash collateral pursuant to this Section 2.15 following (i) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (ii) the determination by the Administrative Agent and such Issuing Bank that there exists excess cash collateral; provided that, subject to this Section 2.15 the Person providing cash collateral and such Issuing Bank may agree that cash collateral shall be held to support future anticipated Fronting Exposure or other obligations; provided further, that to the extent that such cash collateral was provided by the Borrower, such cash collateral shall remain subject to the security interest granted pursuant to the Loan Documents.”

(e) Amendment of Section 3.04. Section 3.04 is hereby revised by inserting a new clause (e):

“(e) Notwithstanding anything herein to the contrary, for purposes of this Section 3.04, (x) the Xxxx-Xxxxx Xxxx Street Reform and Consumer Protection Act and all requests, rules, guidelines or directives thereunder or issued in connection therewith and (y) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, shall in each case be deemed to be a “change in law” or “change in the interpretation of law”, regardless of the date enacted, adopted or issued.”

(f) Amendment of Section 11.06(b). Section 11.06(b) is hereby revised by:

(i) inserting a new clause (viii) as follows:

“(viii) No Assignment to Defaulting Lender. No such assignment shall be made to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute a Defaulting Lender.”

(ii) inserting a new clause (ix) as follows:

“(ix) In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or sub-participations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, the Issuing Bank, each other Lender hereunder (and interest accrued thereon) and the Borrower, and (y) acquire (and fund as appropriate) its full pro rata share of all outstanding Term Loans and/or Revolving Credit Commitments, as applicable, and all participations in Letters of Credit. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.”

(g) Amendment of Schedules to the Credit Agreement. Schedule 2.01 is hereby revised by replacing in its entirety the schedule of Revolving Credit Commitments set forth therein with the schedule of New Revolving Credit Commitments set forth in Annex III hereto.
