(i) select the Participants to whom Awards may from time to time be granted hereunder;

(iv) determine the Performance Goals for Awards for each Participant in respect of each Performance Period based on the Performance Criteria and certify whether the Performance Goals and other material terms of the Award were met prior to the payment of an Award and the calculation of the amount of the Award, if any, payable to each Participant in respect of each Performance Period;

4. AWARDS

4.1. Performance Period; Participant Designation; Performance Goals; Notification.

(a) Not later than the earlier of (i) 90 days after the commencement of each Performance Period or (ii) the expiration of 25% of the Performance Period, and while the outcome of the Performance Goals is substantially uncertain, the Committee shall, in writing designate

(A) one or more Performance Periods,

(B) the Participants for each Performance Period, and

(C) the Performance Goals for determining the Award for each Participant for each Performance Period based on attainment of specified levels of one or any combination of the Performance Criteria. Notwithstanding the foregoing, within such time period, the Committee may also provide for an adjustment to reflect (or for the exclusion of) extraordinary items, acquisitions, divestitures, asset impairment, capital expenditures, unusual or non-recurring items, cost and expenses related to restructuring and/or repositioning, costs and expenditures related to Chapter 11, costs and expenditures related to asbestos, costs and expenditures related to legacy environmental matters, material tax law changes and/or assessments and the cumulative effect of tax or accounting changes.

(b) Notwithstanding any other provision of this Plan, no exclusion or adjustment to a Performance Goal shall be made if the effect of such exclusion or adjustment would be to cause the Award to fail to qualify as "performance-based compensation" within the meaning of Section 162(m) of the Code, if the Award was intended to so qualify.

(c) Designation of any individual as a Participant for any Performance Period shall not require designation of such individual as a Participant in any other Performance Period, and designation of one individual as a Participant shall not require designation of any other individual as a Participant for such Performance Period or for any other Performance Period.

(d) If a person becomes eligible to participate in the Plan after the Committee has made its initial designation of Participants for a Performance Period, such individual may become a Participant if so designated by the Committee, provided that the Award applicable to such individual shall be adjusted to the extent necessary to meet the “performance-based compensation” exception under Section 162(m) of the Code to the extent intended to so qualify.

(e) The Performance Goals designated by the Committee may be expressed with respect to the Company's performance or the performance of one or more Subsidiaries, divisions, business segments or business units of the Company, and may be expressed in terms of dollars, rates of growth, absolute levels or percentages or ratios expressing relationships between two or more of the Performance Criteria, period-to-period changes, relative to business plans or budgets, or relative to one or more other companies or one or more indices. Performance Goals may be calculated for a year or a portion of a year. Such Performance Goals shall otherwise comply with the requirements of the “performance-based compensation” exception under Section 162(m) of the Code for Awards intended to so qualify.

(f) As soon as practicable after they have approved the items set forth in Section 4.1(a) above, the Committee will:

(i) notify each individual who has been selected to participate in the Plan that he or she is a Participant for such Performance Period; and

(ii) communicate in writing to each Participant the applicable Performance Criteria and Performance Goals for determining Awards for such Performance Period.

4.2. Certification. At such time as it shall determine appropriate following the conclusion of each Performance Period and prior to payment of any Award, the Committee shall certify, in writing, whether the Performance Goals and other material terms of the Award were met and the amount, if any, of the Award for each Participant for such Performance Period.

4.3. Payment of Awards.

(a) The amount of the Award actually paid to a Participant may, in the sole discretion of the Committee, be less than the amount otherwise payable to the Participant based on attainment of the Performance Goals for the Performance Period as determined in accordance with Section 4.1. The Committee may not waive the achievement of the applicable Performance Goals for any award intended to qualify as "performance-based compensation" within the meaning of Section 162(m) of the Code, except in the case of the death or disability of the Participant or as described in Section 4.6 in the event of a “Change in Control of the Company” (as defined therein). The Committee may establish factors to take into consideration in implementing its discretion to reduce the amount of an Award, including, but not limited to, individual performance and/or one or more of the Performance Criteria. In no event may the Committee increase the amount of the Award otherwise payable to the Participant based on attainment of the Performance Goals for the Performance Period.

(b) The actual amount of the Award determined by the Committee for a Performance Period shall be paid in cash. Payment to each Participant shall be made no later than the fifteenth day of the third month following the end of the fiscal year of the Company in which the applicable Performance Period ends, unless payment is deferred pursuant to a plan or arrangement satisfying the requirements of Section 409A of the Code.

4.4. Changes in Employment.

(a) If

(i) a person becomes a Participant during a Performance Period as specified in Section 4.1, or

(ii) a Participant (x) dies, retires (within the meaning of a Company retirement plan) or becomes disabled or (y) is terminated by the Company due to a reduction in force, job elimination, divestment of the Participant’s employing unit or other termination not for “cause” (as determined by the Committee) in each case prior to the end of a Performance Period (provided the Participant has more than three months service during such

Performance Period),

then the Participant may be deemed to have participated for the entire Performance Period and the Award, payable to such a Participant may be proportionately reduced based on the period of actual employment during the applicable Performance Period. Notwithstanding the forgoing, as specified in Section 4.3(a), the Committee may waive the achievement of the Performance Goals for a Performance Period for purposes of payment of an Award, in the case of death or disability of the Participant, or in the case of a “Change in Control of the Company”, but only in such cases.  

(b) Except as otherwise specifically provided in this Section 4.4, if the Participant's employment with the Company is terminated prior to the end of a Performance Period for any other reason, the Participant will not be entitled to any Award for such Performance Period unless otherwise determined by the Committee or unless otherwise required by law and in no event unless the Performance Goals and other material terms of the Award are certified in writing by the Committee as having been met.

(c) Notwithstanding the foregoing provisions of this Section 4.4, the Committee may provide that a Participant shall not be paid an Award for a specific Performance Period, even if the Participant is employed at the end of that Performance Period, if the Participant separates from service before the date payments of Awards are made to other Participants for that Performance Period.

4.5. Transfers and Changes in Responsibilities. If a Participant's responsibilities materially diminish to a level, or the Participant is transferred during a Performance Period to a position, that is not deemed by the Committee as eligible to participate in the Plan, the Company may, as determined by the Committee, terminate the Participant's participation in this Plan. In the event of such termination, the Participant would be eligible for a prorated Award based on the number of months in such Performance Period prior to such termination. Such Award would be paid only after the end of such Performance Period and only if the Performance Goals and other material terms of the Award are certified in writing by the Committee as having been met.

4.6. Change in Control.

(a) In connection with any “Change in Control of the Company” (within the meaning of the “Executive CIC Agreement” as defined below), which occurs during a Performance Period, the Committee will take all such actions hereunder as it may determine to be necessary or appropriate in connection with Awards for such Performance Period to treat Participants equitably, including without limitation, the modification or waiver of applicable Performance Goals, Performance Criteria, Performance Periods, or Awards, notwithstanding the terms of any initial award.

(b) “Executive CIC Agreement” shall mean the executive severance agreement between each of the elected officers of W. R. Grace & Co. and the Company, as amended from time to time, which generally provides post-employment payments and benefits to these officers, upon a change in control of the Company.

4.7. Maximum Award. The maximum value of Award payable under the Plan granted to any Participant for any Performance Period is $3,000,000, adjusted pro rata for a Performance Period shorter than 12 months.

5. MISCELLANEOUS

5.1. Amendment and Termination of the Plan. The Board or the Committee may, from time to time, alter, amend, suspend or terminate the Plan as it shall deem advisable, subject to any requirement for stockholder approval imposed by applicable law, including Section 162(m) of the Code, or by the New York Stock Exchange (or such other principal securities market on which the Company's securities are listed or qualified for trading). No amendments to, or termination of, the Plan shall in any way impair the rights of a Participant under any Award previously granted without such Participant's consent.

5.2. Section 162(m) of the Code. To the extent an Award is intended to constitute “performance-based compensation” thereunder, the provisions of this Plan shall be administered and interpreted in accordance with Section 162(m) of the Code.

5.3. Tax Withholding. The Company or any Subsidiary shall have the right to make all payments or distributions pursuant to the Plan to a Participant, net of any applicable federal, state and local taxes required to be paid or withheld. The Company or a Subsidiary shall have the right to withhold from wages, Awards or other amounts otherwise payable to such Participant any such taxes as may be required by law, or to otherwise require the Participant to pay or provide for the payment of any such taxes in a manner satisfactory to the Company or such Subsidiary. If the Participant shall fail to make such tax payments as are required, the Company or a Subsidiary shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to such Participant or to take such other action as may be necessary to satisfy such tax obligations.

5.4 . Right of Discharge Reserved; Claims to Awards. Nothing in this Plan shall provide any Participant a right to receive any Award or payment under the Plan with respect to a Performance Period. Nothing in the Plan nor the grant of an Award hereunder shall confer upon any Participant the right to continue in the employment of the Company or a Subsidiary or affect any right that the Company or a Subsidiary may have to terminate the employment of (or to demote or to exclude from future Awards under the Plan) any such Participant at any time for any reason. Except as specifically provided herein or in any agreement or other instrument entered or adopted into in connection with this Plan, the Company shall not be liable for the loss of existing or potential profit from any Award granted in the event of the termination of employment of any Participant.

5.5. Other Plans. Nothing contained in the Plan shall prevent the Board from adopting other or additional compensation arrangements, subject to stockholder approval if such approval is required; and such arrangements may be either generally applicable or applicable only in specific cases.

5.6 . Severability. If any provision of the Plan shall be held unlawful or otherwise invalid or unenforceable in whole or in part by a court of competent jurisdiction, such provision shall (a) be deemed limited to the extent that such court of competent jurisdiction deems it lawful, valid and/or enforceable and as so limited shall remain in full force and effect, and (b) not affect any other provision of the Plan or part thereof, each of which shall remain in full force and effect. If the making of any payment or the provision of any other benefit required under the Plan shall be held unlawful or otherwise invalid or unenforceable by a court of competent jurisdiction, such unlawfulness, invalidity or unenforceability shall not prevent any other payment or benefit from being made or provided under the Plan, and if the making of any payment in full or the provision of any other benefit required under the Plan in full would be unlawful or otherwise invalid or unenforceable, then such unlawfulness, invalidity or unenforceability shall not prevent such payment or benefit from being made or provided in part, to the extent that it would not be unlawful, invalid or unenforceable, and the maximum payment or benefit that would not be unlawful, invalid or unenforceable shall be made or provided under the Plan.

5.7. Clawback. All awards shall be subject to recovery by the Company in such circumstances as may be prescribed by the Committee at any time or from time to time, if the Committee deems such recovery to be necessary to ensure compliance with any rules, regulations or listing standards adopted by the Securities and Exchange Commission or the New York Stock Exchange to implement Section 10D of the Securities and Exchange Act, as required by the Dodd-Frank Wall Street Reform and Consumer Protection Act.

5.8. Section 409A. The Company intends that the Plan and each Award granted hereunder shall comply with, or be exempt from, Section 409A of the Code and that the Plan shall be interpreted, operated and administered accordingly. If any provision of the Plan contravenes any regulations or guidance promulgated under Section 409A or would cause any Award to be subject to taxes, interest or penalties under Section 409A, the Company may, in its sole discretion, modify the Plan to (a) comply with, or avoid being subject to, Section 409A, (b) avoid the imposition of taxes, interest and penalties under Section 409A, and/or (c) maintain, to the maximum extent practicable, the original intent of the applicable provision without violating the provisions of Section 409A. The Company is not obligated to modify the Plan and there is no guarantee that any payments will be exempt from taxes, interest and penalties under Section 409A. Notwithstanding anything herein to the contrary, in no event shall the Company be liable for the payment of, or gross up in connection with, any taxes, interest and or penalties owed by the Participant pursuant to Section 409A.

5.9 Unfunded Status of the Plan. The Plan is intended to constitute an "unfunded" plan for incentive compensation. With respect to any payments not yet made to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general creditor of the Company.

5.10. Governing Law. The Plan and all determinations made and actions taken thereunder, to the extent not otherwise governed by the Code or the laws of the United States, shall be governed by the laws of the State of Delaware without reference to principles of conflict of laws that might result in the application of the laws of another jurisdiction, and shall be construed accordingly.

5.11. Effective Date of Plan. The Plan shall be effective as of January 1, 2015 subject to approval by the Company's stockholders in accordance with Section 162(m) of the Code. Awards under the Plan are contingent on approval of the Plan by Company stockholders and shall be null and void if such approval is not obtained.
