Dear fellow Grace shareholders:
Change and renewal have been constant themes during Grace’s 167 years as a business enterprise. We have remade our company many times over those years, and that process continues today as we rebuild our portfolio for higher growth. As some markets mature, new opportunities to create value emerge.
Our pursuit of higher growth is based on our intense focus on delivering value to customers, proven innovation capabilities, and high-performance culture, all strengths built over decades. Today 62% of our sales come from our fastest-growing businesses, and we are investing to accelerate our growth strategy.
Sustainability is a core element of our growth. In 2020, a remarkable 49% of our sales directly contributed to our customers' sustainability objectives. And 62% of our R&D projects are tied to at least one of four customer sustainability drivers. We’ve set clear, ambitious environmental goals for our manufacturing operations including a 22% reduction in greenhouse gas emissions by 2030. Grace is rated near the top of our peer groups by Sustainalytics and EcoVadis.
When I consider the growth investments we are making, the strong customer demand for our high-value technologies, and the sustainability benefits we deliver to our customers, I am confident in our strategy to deliver value to our customers, investors, and employees. That confidence is shared by our leadership team and Grace employees worldwide.
On April 26, 2021, we announced an agreement to be acquired by Standard Industries Holdings Inc. in an all-cash transaction valued at approximately $7.0 billion. The closing of this transaction is subject to customary closing conditions, including approval by Grace shareholders and the receipt of certain regulatory approvals, and is expected to close in the fourth quarter of 2021. Shareholders will receive a second proxy statement later this year with information about the merger agreement and instructions for voting on the merger.
On behalf of the Grace Board and our employees, thank you for your investment in Grace and our strategy for the future.
Sincerely,
laforcesignaturefromria021a.jpg
Hudson La Force
President and CEO



Grace At a Glance
WHAT IS GRACE?
We are a high-value specialty chemicals company with industry-leading technologies and deep, long-standing customer relationships.
Customers around the world use our technologies to make essential every-day products ranging from safe food packaging to pharmaceuticals to cleaner transportation fuels.
We have a differentiated, customer-focused sustainability strategy. In 2020, 49% of our sales directly contributed to our customers' sustainability objectives.
WHAT WE ACHIEVED IN 2020?
We acted quickly and decisively to keep our people safe and healthy and our plants operating during the pandemic.
After Q2 sales declined 19%, we delivered a very strong finish to the year with 4Q20 sales at more than 95% of pre-pandemic levels. Our 4Q20 gross margins were also nearing pre-pandemic levels.
We delivered strong operating performance and cash flow with lower capital spending, improved working capital, and reduced operating costs. See “Compensation Discussion and Analysis” below for our Adjusted Free Cash Flow performance.
These actions ensured we could protect our growth investments and R&D spending:
We signed a record seven new UNIPOL® Polypropylene Process licenses in our Specialty Catalysts business
We grew our Pharma & Consumer subsegment 12.4% in Materials Technologies
We safely started two significant new manufacturing plants
We were rated near the top of our peer groups by Sustainalytics and EcoVadis.
We protected our investments in people, including over $6 million of commercial excellence investment and over 50,000 hours of training since 2016. We refreshed more than 10% of our global workforce, including upgrading talent where needed and adding key leadership roles throughout the organization.
WHAT IS DRIVING US FORWARD?
Long-term macro trends including a growing global middle class, increasing demand for health and wellness, and increased emphasis on sustainability. We are #1 or #2 in 80% of our end markets and benefit from strong customer demand for our high-value technologies.
We are successfully building a higher growth portfolio, including strategic acquisitions and increased capacity in our higher growth businesses. Our long-term mid-single digit sales growth target remains unchanged.
We are actively upgrading our capabilities and talent to ensure we continue meeting the high expectations of our customers and capture the growth opportunities in our end markets.
Our experienced, diverse global team. On our Board, 29% of our independent directors are women; on the Grace Leadership Team, 50% are women or people of color, including three of four business unit leaders.

Corporate Governance

Corporate Governance
How We Are Selected, Elected, Evaluated and Refreshed
Nominees for Director in 2021
Our Board determined that each of Chief Executive Officer; Electionthe nominees qualifies for election as a member of Director
our Board. In 2017, we announcedmaking this determination, our Board believes that Fred Festa intendsdirectors should have the highest integrity, a diverse set of attributes and experiences, the education and ability to retireunderstand business problems and evaluate and propose solutions, the personality to work well with others, a commitment to the interests of our shareholders, a reasoned commitment to our social responsibilities, and the time to meet their responsibilities as directors. Our Board further believes that a substantial majority of our directors should be independent. Our Board has determined that Mr. Tomkins qualifies as an independent director under applicable rules and regulations and Grace’s independence standards. Since Mr. La Force is our President and Chief Executive Officer, he is not considered independent. See information contained in the “Corporate Governance—Number and Independence of Directors” section of this Proxy Statement, below.
If a nominee becomes unable to serve or for good cause will not serve as a director, the proxies will vote in their discretion for a Board-designated substitute or our Board may reduce the number of directors. Grace has no reason to believe that any of the Companynominees for election will be unable to serve.
Number and Independence of Directors
Our Board determines the number of directors. Currently, our Board consists of eight members. Under our Corporate Governance Principles, a substantial majority of Grace’s directors are required to be “independent” as determined under guidelines set forth in the listing standards of the New York Stock Exchange, or “NYSE.” Our Board, at its February 25, 2021, meeting, affirmatively determined that all of our directors, other than Mr. La Force, are independent under NYSE rules, because none of the directors has any direct or indirect material relationship with Grace or our subsidiaries under those rules.
The independence determination by the Board with respect to all directors (other than Mr. La Force) included the following:
None of these directors has any material relationship with Grace (either directly or as a partner, shareholder or officer of an organization that has a relationship with Grace).
None of these directors are, or have been within the last three years, an employee of Grace, nor is there an immediate family member who is, or has been within the last three years, an executive officer of Grace.
None of these directors received, nor is there an immediate family member who has received, during any 12-month period within the fourth quarterlast three years, more than $120,000 in direct compensation from Grace, other than director and committee fees.

14    W. R. GRACE & CO.


None of 2018.these directors: (i) is a current partner or employee of a firm that is Grace’s internal or external auditor; (ii) has an immediate family member who is a current partner of such a firm; (iii) has an immediate family member who is a current employee of such a firm and personally works on Grace’s audit; and (iv) was, or has an immediate family member who was within the last three years a partner or employee of such a firm and personally worked on Grace’s audit within that time.
None of these directors or any immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of Grace’s present executive officers at the same time serves or served on that company’s compensation committee.
None of these directors or any immediate family member is a current executive officer of a company that has made payments to, or received payments from, Grace for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million, or 2% of such other company’s consolidated gross revenues.
None of these directors, nor any member of their immediate families, is an executive officer of any other entity with whom Grace does any material amount of business.
None of these directors serve, or within the last five years served, as an executive officer, director, trustee or fiduciary of any charitable organization to which Grace made any material charitable donation.
Two directors resigned from our Board in 2020: (i) Jeffry N. Quinn resigned from our Board, effective March 1, 2020; and (ii) Kathleen G. Reiland, resigned from our Board, effective October 13, 2020, based on her disagreement with the Board regarding Grace’s strategic direction. Both Mr. FestaQuinn and Ms. Reiland had served on the Board’s Audit, Compensation, Nominating and Governance, and Corporate Responsibility Committees prior to their resignations, and each was an independent director under NYSE rules and the aforementioned independence standards.
There are no family relationships among any of our directors or executive officers.
Director Terms
Our Amended and Restated Certificate of Incorporation provides for the division of our Board into three classes, each to serve for a three-year term and until their respective successors are duly elected and qualify. The term of one class of directors currently expires each year at the annual meeting of shareholders. Our Board may fill a vacancy by electing a new director to the same class as the director being replaced. Our Board may also create a new director position in any class and elect a director to hold the newly created position. At the 2021 Annual Meeting, the shareholders will continuevote on the election of two Class I Directors to serve for a term expiring at our 2024 annual meeting of shareholders.
Over the last several years, the Board has undergone significant refreshment through the addition of new members and the departure of longer-serving members.
Director Identification and Selection
When our Board or the Nominating and Governance Committee has identified the need to add a new Board member with specific qualifications or to fill a vacancy on our Board, the Chair of the Nominating and Governance Committee will initiate a search, seeking input from other directors and management, review any candidates that the committee has previously identified or that have been recommended by shareholders in that year, and may retain a search firm. The committee will identify the initial list of candidates who satisfy the specific criteria, if any, and otherwise qualify for membership on our Board. Generally, the Chair of the Nominating and Governance Committee, together with two other members of that committee, and our CEO, will interview each qualified candidate. Other directors may also interview the candidate if practicable. Based on a successful outcome of those reviews, the committee will make its recommendation on the candidate to our Board.
The Nominating and Governance Committee has the sole authority to retain and terminate any search firm to be used to identify director candidates and the sole authority to approve the search firm’s fees and other retention

15    W. R. GRACE & CO.


terms.
Based on the belief that the Board’s effectiveness is enhanced by having an appropriate mix of longer-serving directors, who have a valuable understanding of our businesses, and newcomers who bring fresh viewpoints, the Nominating and Governance Committee has pursued a multi-year refreshment initiative which has significantly improved our Board’s diversity. As of March 31, 2021, the median tenure of our independent directors was slightly over six years, with only two independent directors having served for more than ten years. Presently, 29% of our independent directors are women.
Director Evaluations
Our Board conducts a self-evaluation process every year and periodically reviews the skills and characteristics needed by our Board. As part of the director evaluation review process, our Board considers the skill areas represented on our Board, those skill areas represented by directors expected to retire or leave our Board in the near future, and recommendations of directors regarding skills that could improve the ability of our Board to carry out its responsibilities.
Our Board and committee self-evaluation process starts with the distribution of extensive questionnaires seeking feedback regarding, among other things: responsibilities and contributions; culture and atmosphere; meetings and materials; and continuous improvement. The compiled responses become the basis for discussions in executive sessions in Board and committee meetings early each year. Thereafter, based on the evaluation results, the Board and committees consider changes to their practices and implement such improvements, when appropriate. As a result of these evaluations and discussions, the Board has taken actions such as updating Board and Committee Charters, responsibilities, and information management practices.
How We Are Organized
Under our Corporate Governance Principles, our Board makes a determination as to whether our CEO should also serve as the Board Chair. The Board makes this determination as part of the succession planning process, based upon the composition of our Board, and the circumstances of Grace at the relevant time. In 2019, the Board appointed Mr. Steffen to serve as independent, non-executive Chairman of our Board. Our Board believes that this leadership structure is appropriate for Grace and is in the best interests of Grace shareholders at this time.
As the independent Board Chair, Mr. Steffen presides at all meetings of our Board; calls and presides over executive sessions of the independent directors at each Board meeting; acts as primary liaison with the independent directors; approves Board meeting agendas; approves meeting schedules to assure that there is sufficient time for discussion of all agenda items; consults with the CEO on major issues in advance of each Board meeting; and calls meetings of the independent directors. He also serves as a contact for Grace shareholders who wish to communicate with our Board. Prior to Mr. Steffen’s appointment as non-executive Chairman, he served as the Company’s Lead Independent Director.
Interested parties may communicate with Mr. Steffen by writing to him at the following address: Christopher J. Steffen, Chairman, c/o W. R. Grace & Co., 7500 Grace Drive, Columbia, Maryland 21044.
Standing Committees of our Board of Directors
Our Board has the following four standing committees: (i) Audit Committee; (ii) Nominating and Governance Committee; (iii) Compensation Committee; and (iv) Corporate Responsibility Committee. Only independent directors, as independence is determined in accordance with NYSE rules, are permitted to serve on the standing committees. The Board annually selects, from among its members, the members and Chair of each standing committee.
The table below provides information with respect to current standing committee memberships of the directors as

Each standing committee has a written charter that describes its responsibilities. Each of the standing committees has the authority, as it deems appropriate, to independently engage outside legal, accounting or other advisors or consultants. In addition, each standing committee annually conducts a review and evaluation of its performance and reviews and reassesses its charter. You can find the current charters of each standing committee on our website at www.grace.com/en-us/corporate-leadership/Pages/Governance.aspx.
Audit Committee
The Audit Committee has been established in accordance with the provisions of the Securities Exchange Act of 1934, as amended, or the “Exchange Act,” the rules of the NYSE, and our Corporate Governance Principles. The Audit Committee assists our Board in overseeing:
the integrity of Grace’s financial statements;
Grace’s compliance with legal and regulatory requirements;
the qualifications and independence of the independent auditors;
the performance of Grace’s internal audit function and independent auditors;
Grace’s systems of disclosure controls and procedures and internal controls over financial reporting; and
the preparation of the internal control report and an audit committee report as required by the United States Securities and Exchange Commission, or the “SEC.”
The Audit Committee has the authority and responsibility for the appointment, retention, compensation, oversight and, if circumstances dictate, discharge of Grace’s independent auditors, including pre-approval of all audit and non-audit services to be performed by the independent auditors. The independent auditors report directly to the Audit Committee and, with the internal auditors, have full access to the Audit Committee and routinely meet with the Audit Committee without management being present. The Audit Committee is also responsible for reviewing, approving and ratifying any related party transaction.
All of the members of our Audit Committee meet the independence standards of the SEC and NYSE, are financially literate within the meaning of the NYSE listing standards and meet the experience and financial requirements of the

17    W. R. GRACE & CO.


NYSE listing standards. Mr. Tomkins serves as Chair of the Audit Committee. Our Board determined that Mr. Tomkins is an “audit committee financial expert” as defined by SEC rules and regulations. A number of our other independent directors would also qualify as audit committee financial experts.
Nominating and Governance Committee
The Nominating and Governance Committee
sets criteria for the selection of directors, identifies individuals qualified to become directors, and recommends to our Board the director nominees for the annual meeting of shareholders;
develops and recommends to our Board appropriate corporate governance principles applicable to Grace; and
oversees and administers the evaluation of our Board, its committees and management.
In considering candidates for election to our Board (including candidates recommended by shareholders), we believe that our Board should be comprised of individuals meeting the qualifications set forth above under “Proposal One—Election of Directors.” We value diversity in all its forms and work to ensure that our Board reflects diversity of gender and other attributes as well as diversity of industry experience, and functional background. When we undertake searches for new members of our Board, we focus on gender and racial/ethnic diversity as well as candidate’s skills, experiences and other attributes. We also announcedbelieve that a substantial majority of our Board should be independent, as partdefined by NYSE rules and applicable laws and regulations.
Each member of the Nominating and Governance Committee meets the independence standards of the NYSE. Mr. Steffen serves as Chair of the Nominating and Governance Committee.
Compensation Committee
The Compensation Committee
approves all compensation actions with respect to nonemployee members of the Board and executive officers of the Company;
evaluates and approves the Grace annual and long-term incentive compensation plans (including equity-based plans);
oversees the development of succession plans for the CEO and the other executive officers; and
produces and approves an annual report on executive officer compensation as required by applicable law.
The committee engaged Willis Towers Watson, or “WTW,” a leading global advisory, broking and solutions company, as its independent provider of compensation consulting services for decisions relating to 2020 compensation. Please see “Executive Compensation—Compensation Discussion and Analysis” in this Proxy Statement for more discussion about the role of WTW. The committee also utilizes external legal advisors as necessary and assesses the independence of all of its succession plan,advisors.

For portions of those meetings, the Company's President and CEO, and our Senior Vice President, Human Resources and Information Technology, and Chief OperatingHuman Resources Officer as(our “CHRO”), also attended and were given the opportunity to express their views on executive compensation to the committee.
Each member of the Compensation Committee is independent under the independence standards of the NYSE; a director. Mr. La Force joined“nonemployee director” of Grace as Chief Financial Officerdefined under Rule 16b-3 of the Exchange Act; and an “outside director” for the purposes of the corporate compensation provisions (previously) contained in 2008,Section 162(m) of the Internal Revenue Code of 1986, as amended, or Tax Code.

How We Govern
Corporate Governance Principles
Our Board of Directors has adopted the Grace Corporate Governance Principles to provide a framework for the governance of Grace, and to promote the efficient functioning of our Board. These principles are subject to modification byreviewed, and updated as appropriate, our Board from time to time. governance highlights include:
An independent board chair
A majority voting standard for uncontested director elections
A small, steadily refreshed board
Seven independent directors two of whom are women
A management team of ten that, as of early 2021, includes two minorities and four women; three of four business leaders are diverse
Best practice internal and external pay parity
100% of NEOs have made personal investments in company equity
A clawback policy covering ethics violations and financial misconduct resulting in restatements
You can find the Grace Corporate Governance Principles on our website at www.grace.com/en-us/corporate-leadership/Pages/Governance.aspx.
Number and Independence of Directors
Our Board of Directors determines the number of directors. Our Board currently consists of nine members. Under our Corporate Governance Principles, a substantial majority of Grace’s directors are required to be “independent” as determined under guidelines set forth in the listing standards of the New York Stock Exchange, or NYSE. Our Board, at its February 22, 2018 meeting, affirmatively determined that all directors, other than Mr. Festa (who is also our Chief Executive Officer) and Mr. La Force (who is also our President and Chief Operating Officer), are independent under NYSE rules because none of such directors has any direct or indirect material relationship with Grace or our subsidiaries under those rules. In addition to the application of the NYSE rules, this determination was based on a number of factors, principal among them were the following:
none of these directors, nor any member of their immediate families, is, or at any time during the last five years was, a Grace executive officer or employee;
none of these directors, nor any member of their immediate families, is an executive officer of any other entity with whom we do any material amount of business;
none of these directors, nor any member of their immediate families has, during the last five years, received any direct compensation from Grace (other than director and committee fees); and
none of these directors serve, or within the last five years served, as an executive officer, director, trustee or fiduciary of any charitable organization to which we made any material charitable donation.
Director Terms
Our Amended and Restated Certificate of Incorporation provides for the division of our Board of Directors into three classes, each to serve for a three-year term. The term of one class of directors currently expires each year at the annual meeting of stockholders. Our Board may fill a vacancy by electing a new director to the same class as the director being replaced. Our Board may also create a new director position in any class and elect a director to hold the newly created position. At the 2018 Annual Meeting, the stockholders will vote on the election of three Class I Directors to serve for a term expiring at our 2021 annual meeting of stockholders.

Board LeadershipLead Independent Director
Under our Corporate Governance Principles, our Board of Directors makes a determination as to whether the Chief Executive Officer should also serve as Chairman of the Board of Directors. This determination is based upon the composition of our Board and the circumstances of Grace at the time. Our Board believes that this issue is part of the succession planning process. Mr. Festa, our current Chairman and Chief Executive Officer, intends to retire as Chief Executive Officer during the fourth quarter of 2018. Mr. Festa would continue as non-executive Chairman of our Board.
Mr. Steffen, one of our independent directors, has been elected by the independent directors to serve as the Lead Independent Director. The Lead Independent Director: presides at all meetings of our Board at which the Chairman is not present; calls and presides over executive sessions of the independent directors at each Board meeting; acts as primary liaison between the Chairman and the independent directors; approves Board meeting agendas with the Chairman; approves meeting schedules to assure that there is sufficient time for discussion of all agenda items; consults with the Chairman on major issues in advance of each Board meeting; and calls meetings of the independent directors. The Lead Independent Director also serves as a contact for Grace stockholders who wish to communicate with our Board other than through the Chairman. Our Board believes that this leadership structure is appropriate for Grace and in the best interests of Grace stockholders at this time.
Interested parties may communicate with Mr. Steffen by writing to him at the following address: Christopher J. Steffen, Lead Independent Director, c/o W. R. Grace & Co., 7500 Grace Drive, Columbia, Maryland 21044.
Standing Committees of our Board of Directors
Our Board of Directors has the following four standing committees: Audit Committee, Nominating and Governance Committee, Compensation Committee, and Corporate Responsibility Committee. Only independent directors, as independence is determined in accordance with NYSE rules, are permitted to serve on the standing committees. The Board annually selects, from among its members, the members and Chair of each standing committee.
The table below provides information with respect to current standing committee memberships of the directors as of March 13, 2018. In February 2018, the independent directors agreed to rotate certain committee chairs. Ms. Gulyas replaced Mr. Quinn as chair of the Compensation Committee, and Ms. Holder replaced Ms. Gulyas as chair of the Corporate Responsibility Committee. The table also sets forth the number of meetings (including teleconference meetings) held by each Board committee in 2017. We reimburse directors for expenses they incur in attending Board and committee meetings and other activities incidental to their service as directors but we do not pay our directors any separate meeting fees.

Lead Independent Director
Each standing committee has a written charter that describes its responsibilities. Each of the standing committees has the authority, as it deems appropriate, to independently engage outside legal, accounting or other advisors or consultants. In addition, each standing committee annually conducts a review and evaluation of its performance and reviews and reassesses its charter. You can find the current charters of each standing committee on our website www.grace.com/en-us/corporate-leadership/Pages/Governance.aspx.
Audit Committee
The Audit Committee has been established in accordance with the provisions of the Securities Exchange Act of 1934, as amended, or Exchange Act, the rules of the NYSE and our Corporate Governance Principles. The Audit Committee assists our Board of Directors in overseeing:
the integrity of Grace’s financial statements;
Grace’s compliance with legal and regulatory requirements;
the qualifications and independence of the independent auditors;
the performance of Grace’s internal audit function and independent auditors; and
the preparation of the internal control report and an audit committee report as required by the United States Securities and Exchange Commission, or SEC.
The Audit Committee has the authority and responsibility for the appointment, retention, compensation, oversight and, if circumstances dictate, discharge of Grace’s independent auditors, including pre-approval of all audit and non-audit services to be performed by the independent auditors. The independent auditors report directly to the Audit Committee and, with the internal auditors, have full access to the Audit Committee and routinely meet with the Audit Committee without management being present. The Audit Committee is also responsible for reviewing, approving and ratifying any related party transaction.
The Audit Committee members are H. Furlong Baldwin, Robert F. Cummings, Jr., Julie Fasone Holder, Diane H. Gulyas, Jeffry N. Quinn, Christopher J. Steffen and Mark E. Tomkins, each of whom meets the independence standards of the SEC and NYSE, are financially literate within the meaning of the NYSE listing standards and meet the experience and financial requirements of the NYSE listing standards. Mr. Tomkins serves as Chair of the Audit Committee. Our Board of Directors has determined

that Mr. Tomkins is an "audit committee financial expert" as defined by SEC rules and regulations. A number of our other independent directors would also qualify as audit committee financial experts.
Nominating and Governance Committee
The Nominating and Governance Committee:
sets criteria for the selection of directors, identifies individuals qualified to become directors and recommends to our Board the director nominees for the annual meeting of stockholders;
develops and recommends to our Board appropriate corporate governance principles applicable to Grace; and
oversees the evaluation of our Board and management.
In considering candidates for election to our Board (including candidates recommended by stockholders), we believe that our Board should be composed of individuals meeting the qualifications set forth above under "Proposal One—Election of Directors." We wish to ensure that a diversity of experience is reflected on our Board, including a broad diversity of industry experience, product experience and functional background. We also believe that a substantial majority of our Board should be independent, as defined by NYSE rules and applicable laws and regulations.
Our Board conducts a self-assessment process every year and periodically reviews the skills and characteristics needed by our Board. As part of the review process, our Board considers the skill areas represented on our Board, those skill areas represented by directors expected to retire or leave our Board in the near future, and recommendations of directors regarding skills that could improve the ability of our Board to carry out its responsibilities.
When our Board or the Nominating and Governance Committee has identified the need to add a new Board member with specific qualifications or to fill a vacancy on our Board, the chair of the Nominating and Governance Committee will initiate a search, seeking input from other directors and management, review any candidates that the committee has previously identified or that have been recommended by stockholders in that year, and may retain a search firm. The committee will identify the initial list of candidates who satisfy the specific criteria, if any, and otherwise qualify for membership on our Board. Generally, two members of the committee (with one preferably the chair) and our Chairman of the Board and Chief Executive Officer will interview each qualified candidate. Other directors may also interview the candidate if practicable. Based on a satisfactory outcome of those reviews, the committee will make its recommendation on the candidate to our Board.
The Nominating and Governance Committee has the sole authority to retain and terminate any search firm to be used to identify director candidates and the sole authority to approve the search firm's fees and other retention terms.
The Nominating and Governance Committee members are H. Furlong Baldwin, Robert F. Cummings, Jr., Julie Fasone Holder, Diane H. Gulyas, Jeffry N. Quinn, Christopher J. Steffen and Mark E. Tomkins, each of whom meets the independence standards of the NYSE. Mr. Steffen serves as Chair of the Nominating and Governance Committee.
Compensation Committee
The Compensation Committee:
approves all compensation actions with respect to Grace’s directors, executive officers, and certain other members of senior management;
evaluates and approves the Grace annual and long-term incentive compensation plans (including equity-based plans), and oversees the general compensation structure, policies, and programs of Grace;

oversees the development of succession plans for the Chief Executive Officer and the other executive officers; and
produces an annual report on executive officer compensation as required by applicable law.
The committee engaged Willis Towers Watson, a human resources consulting firm, as its independent provider of compensation consulting services for decisions relating to 2017 compensation. Please see "Executive Compensation—Compensation Discussion and Analysis" in this Proxy Statement for more discussion about the role of Willis Towers Watson. The committee also utilizes external legal advisors as necessary and assesses the independence of all of its advisors.
Representatives of Willis Towers Watson regularly attended meetings of the Compensation Committee. For portions of those meetings, the Chairman and Chief Executive Officer and the Vice President and Chief Human Resources Officer also attended and were given the opportunity to express their views on executive compensation to the Compensation Committee.
The Compensation Committee members are H. Furlong Baldwin, Robert F. Cummings, Jr., Julie Fasone Holder, Diane H. Gulyas, Jeffry N. Quinn, Christopher J. Steffen and Mark E. Tomkins, each of whom is: independent under the independence standards of the NYSE; a “non employee director” of Grace as defined under Rule 16b-3 of the Exchange Act; and an “outside director” for the purposes of the corporate compensation provisions (previously) contained in Section 162(m) of the Internal Revenue Code of 1986, as amended, or Tax Code. Ms. Gulyas serves as Chair of the Compensation Committee.
Corporate Responsibility Committee
The Corporate Responsibility Committee assists our Board of Directors and management in addressing Grace’s responsibilities as a global corporate citizen. In particular, the committee counsels management with respect to:
the development, implementation and continuous improvement of procedures, programs, policies and practices relating to Grace’s responsibilities as a global corporate citizen;
the adherence to those procedures, programs, policies and practices at all levels of Grace; and
the maintenance of open communications to ensure that issues are brought to the attention of, and considered by, all appropriate parties.
The Corporate Responsibility Committee members are H. Furlong Baldwin, Robert F. Cummings, Jr., Julie Fasone Holder, Diane H. Gulyas, Jeffry N. Quinn, Christopher J. Steffen and Mark E. Tomkins, each of whom meets the independence standards of the NYSE. Ms. Fasone Holder serves as Chair of the Corporate Responsibility Committee.
Director Attendance at Board of Directors Meetings
Our Board of Directors generally holds six regular meetings per year and meets on other occasions when circumstances require. Directors spend additional time preparing for Board and committee meetings and participating in conference calls to discuss quarterly earnings announcements or significant transactions or developments. Additionally, we may call upon directors for advice between meetings. Our Corporate Governance Principles provide that our Board will meet regularly in executive session without management in attendance. Under our Corporate Governance Principles, we expect directors to regularly attend meetings of our Board and of all committees on which they serve and to review the materials sent to them in advance of those meetings. We expect nominees for election at each annual meeting of stockholdersshareholders to attend the annual meeting. All of the nominees for election at the Annual Meeting this year
Our Board held 16 meetings in 2020. Each director currently serveserving on our Board of Directors.

Our Board of Directors held 11 meetings in 2017. Each director attended 75% or more of the 20172020 meetings of our Board and the Board committees on which the director served in 2017.2020.
Director Attendance at the Annual Meeting
We expect that all of our directors serving on our Board at the time of the Annual Meeting will attend the Annual Meeting pursuant to our Corporate Governance Principles. All of our directors serving on our Board at the time of the 20172020 Annual Meeting of StockholdersShareholders attended that meeting except that Mr. Quinn was absent duemeeting.
Board Role in Strategy Oversight
A key responsibility of our Board is the oversight of the Company’s short-term and long-term strategy. Our directors take an active role in the oversight of the Company’s strategy at both a Board and committee level and hold management accountable for the execution of our strategy. Each of our directors has an obligation to injury.keep informed about the Company’s business and strategy. In doing so, they can better provide guidance to management in

formulating and developing plans and knowledgeably exercise their decision-making authority on matters of importance to the Company.
Each year, our executive team meets to review and, when in the best interests of the Company, adjust the Company’s corporate strategy. Our Board, in turn, conducts its own review of the Company’s long-term strategic plan including its annual operating plan, and advises management on key priorities and our long-term strategy. Throughout the year, the Board receives information and updates from management and actively engages with senior leaders regarding the Company’s progress against its strategic goals.
Board Role in Risk Oversight
Our Board of Directors actively oversees the risk management of Grace, including the risks inherent in the implementation of our strategic plan and the operation of our businesses. Our Board reviews the Grace enterprise risk management program at least annually and considers whether risk management processes are functioning properly and are appropriately adaptedaligned to Grace’s strategy, culture, risk appetite and value-generation objectives. The Grace enterprise risk management program includes reviews of privacy and cybersecurity vulnerability and the actions necessary to enhance the controls and security of our information systems. Our Board provides guidance to management regarding risk management as appropriate for the risks faced by companies in our industry. These activities are supplemented by a rigorous internal audit function that reports directly to the Audit Committee. Our Board also oversees the risks posed by the COVID-19 pandemic and oversees our response to the COVID-19 pandemic.
Standing Board committees are responsible for overseeing risk management practices relevant to their functions. The Audit Committee oversees the management of market and operational risks that could have a financial impact, such as those relating to internal controls and financial liquidity. The Nominating and Governance Committee oversees risks related to governance issues, such as the independence of directors and the breadth of skills on our Board. The Compensation Committee manages risks related to Grace’s executive compensation plans and the succession of the Chief Executive OfficerCEO and other executive officers.officers, and other talent-related risks. The Corporate Responsibility Committee manages certain risks related to government regulation and environment, health and safety matters.matters, including the physical and transitional risks associated with climate change.
StockBoard Role in Human Capital Management
Our Board believes that it has an important responsibility to oversee risks related to human capital, and this responsibility is shared by multiple Board committees as well as the full Board. While the full Board has oversight responsibilities for the overall management of human capital, the Corporate Responsibility Committee has specific responsibilities for reviewing management’s initiatives to promote diversity and inclusion in its talent acquisition, development, and retention programs. In addition, the Compensation Committee has specific responsibilities to review compensation policies and plans to promote the Company’s ability to attract, retain and motivate the talent required to execute our strategy.
Our Board believes it plays an important role as a resource to management in finding ways to extend our inclusive culture. Together, our Board and management seek and support top talent from diverse backgrounds to enhance innovation and to signal the importance of fairness and opportunity as ingredients supporting sustainable performance.

the toughest environmental standards, or to reformulate products to address rising consumer and regulatory expectations for sustainability, human health, and safety. As a leading manufacturer of process catalysts, we have become an active participant in the circular economy, with increasing business in assisting our customers with the recycling or reprocessing of spent catalysts. As part of our commitment to RESPONSIBLE CARE®, we systematically track safety and environmental performance through a comprehensive, global EHS management system covering the environmental, health, safety (including process safety and product safety) and security aspects of our operations, and track progress through pertinent metrics. In 2020, we also provided disclosures in line with the Sustainability Accounting Standards Board (SASB) standard for the chemical industry, and publicly reported our facility carbon emissions and water usage to the Carbon Disclosure Project (CDP). Our Board oversees the Company’s sustainability initiatives, including through its Corporate Responsibility Committee.
Product Portfolio
As part of our periodic strategic review of our product portfolio, we work to identify products that contribute to our customers’ sustainability objectives, including:
Products designed for use-phase efficiency — defined by SASB as products that “through their use-can be shown to improve energy efficiency, eliminate or lower greenhouse gas (GHG) emissions, reduce raw materials consumption, increase product longevity, and/or reduce water consumption,” either through:
Improved products — by increasing the efficiency of a product during its use phase, or
Improved processes — by increasing the efficiency of the manufacturing processes used to make products;
Meeting Strict Environmental Standards — products that directly enable customers to meet environmental regulatory/legal requirements applicable to their products or manufacturing processes; and
Cleaner/Safer Products — products that enable customers to reformulate their products to avoid or reduce to de minimis levels substances of concern to their customers.
We reviewed the requested disclosures from SASB, CDP as well as other ESG ratings organizations and expanded our product categories to include products that make a significant contribution to the move towards a more circular economy through:
Circularity/Enabling Material Recycling and Renewable Feeds — products that are tailored to enable customers to replace petroleum inputs with bio-based and recycled materials, and FCC catalyst sales (not counted above) where Grace takes back spent FCC catalysts for recycling, or otherwise enables the reuse or recycling of spent catalysts.
Together, the products in our portfolio that address these sustainability endpoints accounted for approximately $1.1 billion or 49% of our total revenue in 2020 (including the revenues of our Advanced Refining Technologies LLC joint venture).
ESG Rankings
For 2020, Grace again earned a Gold Rating from EcoVadis, placing the Company in the 95th percentile of all companies ranked by EcoVadis on their sustainability performance. EcoVadis is a leading third-party entity that evaluates suppliers on a complex scale of sustainability and environmental, social, and governance, or “ESG,” factors. Also, in 2020, the ESG Risk Rating from Sustainalytics
placed us in the top quintile of both chemical and specialty companies.

Investor conferences
Analyst meetings
Headquarters events
One-on-one meetings
Investor days
Investor presentations
Video and telephonic conference calls
E-mail communications
Independent perception studies and quarterly sentiment reports (interviews with investors)

Our efforts led to over 300 unique “touch point” engagements with more than 200 buy-side and sell-side firms over the course of the year. Shareholder feedback from our robust engagement program is provided to our Board and management, and these viewpoints are considered in our decision-making.
We provide additional forms of communications directed toward our shareholders, including:

Related Party Transactions
Our Board of Directors recognizes that transactions involving related persons in which Grace is a participant can present conflicts of interest, or the appearance thereof, so our Board has adopted a written policy as part of the Grace Corporate Governance Principles (which are available on our website at www.grace.com/en-us/corporate-leadership/Pages/Governance.aspx)Governance.aspx) with respect to related person transactions. The policy applies to transactions involving related persons that are required to be disclosed pursuant to SEC regulations, which are generally transactions in which:
Grace is a participant;
the amount involved exceeds $120,000; and
any related person, such as a Grace executive officer, director, director nominee, 5% stockholdershareholder or any of their respective family members, has a direct or indirect material interest.

31    W. R. GRACE & CO.


Each such related person transaction shall be reviewed, determined to be in, or not inconsistent with, the best interests of Grace and its stockholdersshareholders and approved or ratified by:
the disinterested members of the Audit Committee, if the disinterested members of the Audit Committee constitute a majority of the members of the Audit Committee; or
the disinterested members of our Board.
In the event a related person transaction is entered into without prior approval and, after review by the Audit Committee or our Board, as the case may be, the transaction is not ratified, we will make all reasonable efforts to cancel the transaction.

Agreements with Certain of our Shareholders
On April 26, 2021, the Company issued a press release announcing the entry into a definitive agreement providing for the acquisition of the Company by an affiliate of Standard Industries Holdings Inc. (“Standard Industries Holdings”), subject to the terms and conditions contained therein. The Company also announced that Standard Industries Holdings’ related investment platform 40 North Latitude Master Fund Ltd. (“40 North”), which owns approximately 14.9% of the Company’s outstanding common stock, had entered into a voting agreement pursuant to which 40 North has agreed to vote its shares of Grace common stock in favor of the transaction.
Merger Agreement
On April 26, 2021, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Gibraltar Acquisition Holdings LLC, a Delaware limited liability company (“Parent”) and a wholly owned subsidiary of Standard Industries Holdings, and Gibraltar Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”), pursuant to which Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent. Our Board has unanimously approved the Merger Agreement.
As a result of the Merger, each share of Grace common stock outstanding immediately prior to the effective time of the Merger (the “Effective Time”) (subject to certain exceptions, including for shares of Grace common stock owned by shareholders of the Company who have not voted in favor of the adoption of the Merger Agreement and have properly exercised appraisal rights in accordance with Section 262 of the General Corporation Law of the State of Delaware (the “DGCL”)) will, at the Effective Time, automatically be converted into the right to receive $70.00 in cash, without interest, subject to applicable withholding taxes (the “Merger Consideration”).
Pursuant to the Merger Agreement, as of the Effective Time, (1) each option to purchase shares of Grace common stock and each stock appreciation right with respect to shares of Grace common stock that is outstanding immediately prior to the Effective Time will vest at closing and be converted into the right to receive an amount in cash equal to the product of Merger Consideration (less the applicable exercise price) and the number of shares of Grace common stock covered by such option (without interest and less applicable withholding taxes) and (2) each restricted stock unit award and each performance-based unit award relating to shares of Grace common stock that is outstanding immediately prior to the Effective Time will be assumed and converted into the right to receive an amount in cash (without interest) equal to the product obtained by multiplying the Merger Consideration by the number of shares of Grace common stock covered by such award immediately prior to the Effective Time, which converted cash award will be subject to continued service vesting and other terms as set forth in the Merger Agreement.
Pursuant to the terms of the Merger Agreement, the Company will suspend payment of its quarterly dividend during the pendency of the transaction.
If the Merger is consummated, the Grace common stock will be delisted from the New York Stock Exchange and deregistered under the Exchange Act.

32    W. R. GRACE & CO.


Closing Conditions
Completion of the Merger is subject to certain mutual closing conditions, including (1) the adoption of the Merger Agreement by holders of a majority of the outstanding shares of Grace common stock, (2) the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and the approval of the Merger under certain other applicable antitrust laws, and (3) the absence of any order, injunction or law prohibiting the Merger. In the case of the Company, completion of the Merger is subject to certain additional closing conditions, including (A) the accuracy of Parent and Merger Sub’s representations and warranties, subject to certain materiality standards set forth in the Merger Agreement, and (B) the performance by Parent and Merger Sub in all material respects of their covenants and agreements under the Merger Agreement. In the case of Parent and Merger Sub, completion of the Merger is subject to certain additional closing conditions, including (X) the accuracy of the Company’s representations and warranties, subject to certain materiality standards set forth in the Merger Agreement, (Y) the performance by the Company in all material respects of its covenants and agreements under the Merger Agreement, and (Z) no Company Material Adverse Effect (as defined in the Merger Agreement) having occurred since the date of the Merger Agreement. The closing of the Merger is not subject to a financing condition. The parties expect the transaction to close in the fourth quarter of 2021.
No Solicitation
The Merger Agreement provides that the Company must comply with customary non-solicitation restrictions, including certain restrictions on its ability to solicit alternative acquisition proposals from third parties, to provide non-public information to third parties and to engage in negotiations with third parties regarding alternative acquisition proposals. Subject to certain customary “fiduciary out” exceptions, our Board is required to recommend that the Company’s shareholders adopt the Merger Agreement and to call a meeting of the Company’s shareholders to vote on a proposal to adopt the Merger Agreement.
Termination and Fees
Either the Company or Parent may terminate the Merger Agreement in certain circumstances, including if (1) the Merger is not completed by January 26, 2022 (subject to extension to April 26, 2022 under certain circumstances described in the Merger Agreement, including for purposes of obtaining required regulatory approvals), (2) a governmental authority of competent jurisdiction has issued a final non-appealable governmental order or law permanently prohibiting the Merger, (3) the Company’s shareholders fail to adopt the Merger Agreement, and (4) the other party materially breaches its representations, warranties or covenants in the Merger Agreement, subject in certain cases, to the right of the breaching party to cure the breach. Parent and the Company may also terminate the Merger Agreement by mutual written consent.
The Company is also entitled to terminate the Merger Agreement, and receive a termination fee of $281 million from Parent, if (1) Parent fails to consummate the Merger following the satisfaction or waiver of certain closing conditions or (2) if Parent otherwise breaches its obligations under the Merger Agreement such that the applicable condition to the consummation of the Merger is not satisfied.
If the Merger Agreement is terminated in certain other circumstances, including by the Company in order to accept a Superior Company Proposal (as defined in the Merger Agreement), or by Parent because our Board withdraws its recommendation in favor of the Merger, the Company would be required to pay to Parent a termination fee of $141 million.
Financing
Parent has obtained equity financing and debt financing commitments for the purpose of financing the transactions contemplated by the Merger Agreement. Standard Industries Holdings has committed to capitalize Parent at the closing of the Merger with an aggregate equity contribution equal to $3,516 million on the terms and subject to the conditions set forth in its equity commitment letter. Standard Industries Holdings has announced that its equity commitment will be supported by the available cash of its subsidiary, Standard Industries Inc., and up to $2,500 million in proceeds from a secured term loan.

J.P. Morgan, BNP Paribas, Citi and Deutsche Bank (the “Lenders”) have agreed to provide Parent with debt financing in an aggregate principal amount of up to $3,455 million on the terms and subject to the conditions set forth in a debt commitment letter. The obligations of the Lenders to provide debt financing under the debt commitment letter are subject to a number of customary conditions.
In addition, Standard Industries Holdings has guaranteed payment of the termination fee payable by Parent under certain circumstances, as well as certain reimbursement obligations that may be owed by Parent pursuant to the Merger Agreement, subject to the terms and conditions set forth in the Merger Agreement and a limited guarantee provided by Standard Industries Holdings to the Company.
Other Terms of the Merger Agreement
The Company has made customary representations, warranties and covenants in the Merger Agreement, including, among others, covenants to use reasonable best efforts to conduct its business in all material respects in the ordinary course during the period between the date of the Merger Agreement and the completion of the Merger. The parties have agreed to take all actions necessary to consummate the merger, including cooperating to obtain the regulatory approvals necessary to complete the Merger.
The foregoing description of the Merger Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, a copy of which has been filed with the SEC.
The Merger Agreement has been filed with the SEC to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company, Parent, Merger Sub or their respective affiliates. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of the Merger Agreement as of the specific dates therein, were solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk among the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties thereto or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be reflected in the Company’s public disclosures. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the Company, Parent and Merger Sub and the transactions contemplated by the Merger Agreement that will be contained in or attached as an annex to the proxy statement on Schedule 14A that the Company will file in connection with the transactions contemplated by the Merger Agreement, as well as in the other filings that the Company will make with the SEC.

The foregoing description of the Voting Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Voting Agreement, a copy of which has been filed with the SEC.

In addition, the Company agreed in the 2021 Letter Agreement that, if the 40 North Parties delivered a notice of nomination of director candidates for the 2021 Annual Meeting on or before the fifteenth day following the expiration or termination of the Standstill Provisions, which notice of nomination otherwise complied with the requirements of the By-Laws, the Company would hold its 2021 Annual Meeting no earlier than 60 days from the date of such notice of nomination.

The 40 North Parties did not submit a nomination of director candidates for the 2021 Annual Meeting during the applicable time period set forth in the 2021 Letter Agreement, as extended.
On February 20, 2019, we entered into an agreement with the 40 North Parties pursuant to which, among other things, we included Mr. Slack and Ms. Reiland on the slate of director nominees recommended by our Board in the Proxy Statement for our 2019 Annual Meeting of Shareholders. Mr. Slack and Ms. Reiland were elected as directors at that meeting. Prior to our 2020 Annual Meeting of Shareholders, our Board appointed Ms. Reiland as a Class I director with a term expiring at our 2021 Annual Meeting of Shareholders. Effective October 13, 2020, Ms. Reiland resigned from the Company’s Board and all of its committees based on her disagreement with the Board regarding the Company’s strategic direction. Ms. Reiland had served on the Board’s Audit, Compensation, Nominating and Governance, and Corporate Responsibility Committees.

This vote is generally referred to as a "Say“Say on Pay"Pay” vote. Accordingly, we are asking stockholdersshareholders to approve, on an advisory basis, the following resolution:

This vote is advisory and not binding on Grace, the Compensation Committee, or our Board. However, as the vote is an expression of our stockholders’shareholders’ views on a significant matter, the Compensation Committee will consider the outcome of the vote when making future executive compensation decisions. We currently hold such advisory vote each year and would expect to hold another advisory vote at our 20192022 Annual Meeting of Stockholders.Shareholders (if held), pending the shareholder vote under Proposal Four set forth in this Proxy Statement.
The principal components of pay under our 20172020 executive compensation program were annual base salary, annual cash incentive awards, and long-term incentive awards, which consisted of stock options, performance-based units, or "PBUs,"PBUs and restricted stock units, or "RSUs."RSUs. The performance measures for the 20172020 annual cash incentive awards were Adjusted EBIT (weighted 50%), Adjusted Free Cash Flow (weighted 25%), and Adjusted Net Sales (weighted 25%). For PBUs, which represent approximately 50% of the value of our Long-Term Incentive Plan, or "LTIP,"“LTIP,” awards, the amount of an individual payout under a performance-based unitPBU award is based upon: an award recipient’s performance-based unitPBU target share amount; the growth in our LTIP Adjusted EPS over the three-year performance period; the Total Shareholder Return (or “TSR”) for the three-year performance period as compared to a similar figure for the Russell 1000 Index; and the value of Grace common stock on the payout date. We encourage our stockholdersshareholders to read the Compensation Discussion and Analysis set forth under "Executive Compensation"“Executive Compensation” which describes our 20172020 compensation program in detail as well as Annex A hereto, which provides important information about Non-GAAPnon-GAAP performance measures.

If so approved, the 2018 Plan will supersede the 2014 Stock Incentive Plan (the “2014 Plan”), and no additional awards would be made under the 2014 Plan or under our Amended and Restated 2011 Stock Incentive Plan. Approval of the 2018 Plan will not affect awards previously granted under those plans.
The Company is seeking stockholder approval of the 2018 Plan this year in order to: update its compensation program to reflect current market practices and governance standards; increase the number of shares available for issuance above the remaining authorization under the 2014 Plan; and comply with the listingdisclosure rules of the New York Stock Exchange, as described further below.

Upon a grant of restricted stock, restricted stock units or other similar awards (whether performance-based or time-vested) or unrestricted grants of shares of our common stock, the number of shares available for issuance under the 2018 Plan will be reduced by 3.19 times the number of shares subject to such awards.

The maximum aggregate number of shares of W. R. Grace & Co. common stock, par value $.01 per share ("Common Stock"), that may be issued under the 2018 Plan, consisting of Common Stock issued and Common Stock underlying outstanding awards granted on or after the date the 2018 Plan is approved by stockholders, is 7,200,000 shares, plus any shares subject to outstanding awards under the 2014 Plan that are terminated, canceled, forfeited, or expire, or under which the shares otherwise cease to be issued under the 2014 Plan. The aggregate number of Shares available for issuance under the

2018 Plan shall be reduced by 3.19 shares of Common Stock for each share of Common Stock delivered in settlement of any Full Value Award.
Generally if any shares of Common Stock subject to a Stock Incentive are forfeited or expire, or are settled for cash, such shares shall be added back to the shares of Common Stock authorized for grant under the 2018 Plan. To the extent that a Full Value Award is forfeited or expires or such Full Value Award is settled for cash, the shares of Common Stock available under the 2018 Plan shall be increased by 3.19 shares of Common Stock for each share of Common Stock subject to such Full Value Award. However, the following shares of Common Stock shall not be added back to the shares of Common Stock authorized for grant and shall not be available for future grants of Stock Incentives: (i) shares of Common Stock tendered by a Key Person or withheld by the Company in payment of the exercise price of an Option; (ii) shares of Common Stock tendered by the Key Person or withheld by the Company to satisfy any tax withholding obligation with respect to a Stock Incentive; (iii) shares of Common Stock subject to a stock appreciation right, or “SAR,” that are not issued in connection with the stock settlement of the SAR on exercise thereof; and (iv) shares of Common Stock purchased on the open market with the cash proceeds from the exercise of Options. The maximum number of shares of Common Stock that may be subject to Stock Incentives granted to any one Key Person during any one calendaradvisory vote every year shall be limited to one million (subject to adjustment in accordance with the 2018 Plan terms). In addition, the maximum Fair Market Value at the grant date under Stock Incentives granted to any Director during any one calendar year shall not exceed $750,000.
Forms of Stock Incentive Awards
A stock incentive granted under the 2018 Plan (a “Stock Incentive”) may be granted in the form of:
(i)    a Stock Award;
(ii)    an Option or a SAR;
(iii)    a Net Exercise Option; or
(iv)    a combination thereof.
Vesting
Stock Incentives granted under the 2018 Plan shall vest no earlier than the first anniversary of the date the Stock Incentive is granted, subject to certain exceptions specified in the 2018 Plan.
Stock Awards
The material terms of each Stock Award shall be determined by the committee. Each Stock Award shall be evidenced by a written instrument consistent with the 2018 Plan. It is intended that a Stock Award would be made contingent upon the attainment of one or more specified objectives (that may include, for avoidance of doubt, solely the continued service of the recipient) and may be made subject to restrictions on the sale or other disposition of the Stock Award or the shares subject thereto for a period of one or more years (or such other shorter or longer period as the committee may determine).
Stock Options and Stock Appreciation Rights
Stock Incentives in the form of Options and SARs would be subject to the following:
Options. The Option exercise price per share of Common Stock shall not be less than one hundred percent of the Fair Market Value of a share of Common Stock on the date the Option is granted; and such exercise price per share of Common Stock shall not be reduced, by action of the Board of Directors or otherwise, at any time after the date the Option is granted (subject to certain adjustments). The exercise price and any withholding tax that may be due on the exercise of an Option may be paid in cash, or, if so provided in the Option Agreement:

(i) in shares of Common Stock (including shares issued pursuant to the Option being exercised); or (ii) in a combination of cash and such shares, with certain provisos.
SARs. The SAR exercise price per share of Common Stock shall not be less than one hundred percent of the Fair Market Value of a share of Common Stock on the date the SAR is granted; and such exercise price per share of Common Stock shall not be reduced, by action of the Board of Directors or otherwise, at any time after the date the SAR is granted (subject to certain adjustments). Any withholding tax that may be due on the exercise of the SAR may be paid in cash or through withholding on the amounts that would otherwise be paid pursuant to the SAR.
Exercise of Options or SARs. Each Option or SAR shall be exercisable during the life of the holder only by the holder and, after the holder’s death, only by his or her estate or by a person who acquires the right to exercise the Option or SAR by will or the laws of descent and distribution. Unless otherwise provided in the applicable Stock Incentive Agreement, an Option or SAR, to the extent that it shall not have been exercised or canceled, shall terminate as of, or within a specific time period after the holder ceases to serve, depending upon the circumstances of such cessation. No Option or SAR shall be exercisable after expiration of a period of ten years from the date the Option or SAR is granted.
Limited Transferability of Options and SARs. Generally, no restricted stock unit, Option or SAR, nor any right thereunder, may be assigned or transferred except to Permitted Transferees, or by will or the laws of descent and distribution and except, in the case of a Nonstatutory Stock Option or SAR, pursuant to a qualified domestic relations order.
Incentive Stock Options. An Option may, but need not, be an Incentive Stock Option within the meaning of Section 422 of the Tax Code.
Option and SAR Agreements. The material terms of each Option or SAR shall be determined by the committee. Each Option or SAR shall be evidenced by a written instrument consistent with the 2018 Plan; however, an Option or SAR may include restrictions and limitations in addition to those provided for in the 2018 Plan.
No repricing and other limitations regarding Options and SARs. Subject to adjustments in accordance with the 2018 Plan, without the approval of the Company’s stockholders: (i) no transaction or series of transactions shall have the effect of exchanging all or any portion of any Option or SAR granted under the 2018 Plan for, or replacing all or any portion thereof with, a new Option or SAR, where the exercise price per share of Common Stock under the new Option or SAR is less than such exercise price as previously granted; (ii) the committee shall not authorize the amendment of any outstanding Option or SAR to reduce its price per share of Common Stock; or (iii) the Company shall not cancel any Option or SAR in exchange for cash or another Stock Incentive when the Option or SAR exercise price per share of Common Stock exceeds the Fair Market Value of the underlying shares.
Performance Awards
The committee, in its discretion, may authorize the granting, vesting, payment and/or delivery of any form of Stock Incentive as performance awards contingent upon achievement of such performance targets as are selected by the committee. The committee shall determine performance cycles of a period of not less than one year over which the achievement of targets for performance measures is determined.
Dividends on Stock Incentives
In the event that a dividend or dividend equivalent is to be paid (in cash or in stock) in respect of an unvested Stock Incentive, such dividends or dividend equivalents shall be retained by the Company

and shall be paid to the Key Person, subject to the same restrictions and vesting as are applicable to the underlying Stock Incentive. The Company shall not pay cash dividends or dividend equivalents on Options or SARs.
Term
The 2018 Plan would be effective upon approval by the stockholders. The 2018 Plan would terminate, and no Stock Incentives could be issued thereunder, as of the first business day on or after the ten-year anniversary of the stockholder approval, with any previously granted awards remaining in effect until they expire.
Tax Consequences
The Company generally will be entitled to a tax deduction when a Key Person exercises an Option, other than an Incentive Stock Option, or SAR, shares or cash is issued under a Stock Award in the form of a restricted stock unit or a Stock Award in the form of Restricted Stock vests, in an amount equal to the income recognized by the Key Person. However, the deduction is subject to applicable limitations and conditions in the Tax Code, including Section 162(m). Tax Code Section 162(m) will limit a company's annual deduction for compensation in excess of $1 million paid to the CEO, the CFO, and the other highest paid executive officers for such taxable year (including such persons after they have ceased having such status, for example because of a termination of employment).
Nonqualified Stock Options and Stock Appreciation Rights. Subject to compliance with Section 409A of the Tax Code, a participant will not recognize any income at the time a nonqualified stock option or stock appreciation right is granted, nor will we be entitled to a deduction at that time. When a nonqualified stock option is exercised, the participant will recognize ordinary income in an amount equal to the excess of the fair market value of the shares received as of the date of exercise over the exercise price. When a stock appreciation right is exercised, the participant will recognize ordinary income in an amount equal to the cash received or, if the stock appreciation right is paid in shares, the fair market value of the shares received as of the date of exercise. Payroll taxes are required to be withheld from the participant on the amount of ordinary income recognized by the participant. Subject to applicable limitations, we generally will be entitled to a tax deduction with respect to a nonqualified stock option or stock appreciation right at the same time and in the same amount as the participant recognizes income.
Incentive Stock Options (“ISO”). A participant will not recognize any income at the time an ISO is granted, nor will we be entitled to a deduction at that time. In addition, provided the ISO is exercised during or within three months of termination of employment (one year in the case of disability), the participant will not recognize ordinary income at the time of exercise, nor will we be entitled to a deduction at that time. However, the excess of the fair market value of the shares at exercise over the exercise price will be a preference for alternative minimum tax purposes. However, if the shares acquired upon exercise are sold within two years of the grant of the ISO or one year of the exercise of the ISO (a “Disqualifying Disposition”), the participant will recognize ordinary income equal to the excess of the fair market value of the shares at exercise over the exercise price or, if lesser the excess of the fair market value of the shares at sale over the exercise price. Any excess of the amount realized on sale over the fair market value of the shares at exercise will be long term or short term capital gain, as applicable. In the case of a Disqualifying Disposition, subject to applicable limitations, we generally will be entitled to a tax deduction at the same time and in the same amount as the participant recognizes income. In the event of the sale of the shares over two years from the grant of the ISO and one year after the exercise of the ISO, the participant will recognize long term capital gain equal to the excess of the amount realized in the sale over the amount paid for the shares.
Restricted Stock. Unless a participant makes an election under Section 83(b) of the Tax Code (an “83(b) Election”) to accelerate recognition of the income to the date of grant, the participant will not recognize income, and the Company will not be allowed a tax deduction, at the time a restricted stock award containing substantial forfeiture restrictions is granted. In the absence of an 83(b) Election, when

such restrictions lapse, the participant will recognize ordinary income equal to the fair market value of the shares as of that date (less any amount paid for the shares) and the Company will be allowed a corresponding federal income tax deduction. The participant's subsequent sale of the shares will give rise to capital gain or loss equal to the difference between the sale price and the sum of the ordinary income the participant recognized with respect to the shares and any amount the participant paid for the shares, and any capital gains will be taxable as long-term gains if the participant held the shares for more than one year following the date on which restrictions lapsed.
Restricted Units/Deferred Stock Units. Subject to compliance with Section 409A of the Code, a participant will not recognize any income at the time a restricted unit or deferred stock unit is granted, and the Company will not be allowed a tax deduction at that time. Instead, the value of shares delivered on or after the vesting of restricted units or deferred stock units generally will be taxable to the recipient as ordinary income when shares are delivered to the participant.

Compensation Discussion and Analysis
Executive Summary
In 2017,
compensationmixpiecharts-0e.jpg
COVID-19 and Hurricanes Laura and Delta had significant impacts on our business.
The impact of the COVID-19 pandemic, combined with Hurricane-related outages and repairs to vital Grace facilities, caused Grace to perform below plan on adjusted metrics including net sales, EBIT, EPS and free cash flow.
compensationmixpiecharts-1c.jpg
Our management team and Board acted quickly and decisively.
The safety and well-being of our employees and our customers was our first priority. We had no layoffs, limited furloughs, continued all employee benefits, moved nearly half of our employees to remote work, and took action to protect our critical employees in the workplace.
image8a.jpg
We delivered solid operational and financial results and positioned the Company for future growth despite the challenging year.
We met our customer obligations and delivered a very strong finish to 2020. In the short term, we invested in growth, improved cash flow, continued our dividend, and optimized our manufacturing network. We positioned Grace for long-term growth by continuing our product development and growth initiatives without interruption.
image7a.jpg
We focused our employees on free cash flow generation and rewarded the team for their exemplary work.
In April, the Company revised our pre-pandemic 2020 performance metrics under our Annual Incentive Compensation Program (“AICP”) for all participants, except the CEO and his Leadership Team (who retained the original 2020 performance metrics). The revised broad-based plan focused entirely on adjusted free cash flow, which was deemed essential for managing through the pandemic. Plan participants, which includes the vast majority of our workforce, received payouts at an average of 71% of target.
image1.jpg
Annual incentives for the Named Executive Officers (“NEOs”) paid on average at 60% of target.
In early 2021, the Board and the Committee evaluated the Company’s performance relative to the original performance metrics and determined that based solely on the original metrics, payout to the NEOs would be 16% of target AICP opportunity. After considering the performance of each NEO on an individual basis, taking into account, specifically, contributions towards managing the pandemic, meeting customer commitments, delivering financial results, advancing the Grace Value Model, managing human capital risk, promoting diversity and reinforcing our inclusive culture, and taking actions to manage Grace’s environmental footprint, the Committee used its discretion to adjust NEO AICP from 16% of target, as indicated by the formula, to an average of 60% of target.
image2a.jpg
2018-2020 performance-based units (“PBUs”) paid out at approximately 55% of target.
The Company’s PBU awards are tied to specific EPS targets over a three year period. Our Committee used its discretion under the equity incentive plan to bifurcate and pro-rate the 2018-2020 award to recognize (1) above target performance in 2018-2019 and (2) below threshold performance in 2020. Our relative TSR modifier further reduced the payout to 55% of target.
image7a.jpg
We continue to make enhancements to our compensation program.
In 2021, we are eliminating stock options, will use a more aligned comparator group for our relative TSR modifier, and will use a target range for EPS to account for continued market uncertainty.

Grace Value Model
The Grace Value Model (or “GVM”) is an important part of our long-term incentive plan, both of which have beengrowth strategy. The GVM is a tightly aligned operating excellence model designed to alignaccelerate growth and profitability for Grace. At the interests of our executives and stockholders. During 2017,company level, we overcame the challenges posed by an extended outage at a key customer, and hurricane events affecting other customers as well as suppliers, to achieve our annual goals. The Company is well positioned to take advantage of market opportunities and strong demand for our differentiated products in 2018 and beyond.
Key 2017 Fiscal Year Business Performance Metrics and Results
Our net sales were $1,716.5 million for the full year, an increase of 7.4% from 2016, and our Adjusted Net Sales increased 5.3% to $1,683.6 million, including a $32.9 million adjustment for foreign currency.

Diluted earnings per share ("EPS") from continuing operations for the full year were $0.16, including a charge of $2.10 per share related to U.S. tax reform. Our Adjusted EPS for the full year increased 9.7% to $3.40.
We generated Income from continuing operations attributable to Grace shareholders of $11.2 million, versus $107.0 million in 2016 (due to a $143.0 million provisional charge to reflect the estimated effects of U.S. tax reform), and our Adjusted EBIT was $414.0 million, up 3.4%.

Our net cash provided by operating activities from continuing operations was $319.2 million, an increase of 19.3% from 2016, and our Adjusted Free Cash Flow was $274.0 million, up 16.1%.

chart-58feb3f8c1519544e5aa04.jpgchart-cb481a510d55151b873a04.jpg
In addition, Grace returned $122.3 million in value to its stockholders in 2017 through a combination of dividends and shares repurchases as follows:
Increased quarterly cash dividend starting with our first quarter dividend, paying $57.3 million to Grace stockholders during 2017.
Repurchased $65.0 million of Grace common stock under our completed $500 million share repurchase program and our ongoing $250 million program, which we announced on February 8, 2017.
Our results reflect strong performance across the organization, and as a Company we met the challenging goals that we set in our 2017 operating plan. As a result, we funded 100% of the target Annual Incentive Compensation Plan (AICP) pool.
Overcoming Headwinds to Achieve Our Goals
During 2017, one of our key Catalysts Technologies customers experienced an explosion and fire that resulted in an extended outage. Extreme hurricane events caused other customer and supplier outages. Despite these challenges, we increased net sales by 7% by adopting new strategies to address these challenges and following the Grace Core Values of teamwork, performance, innovation, speed and integrity. With executive leadership and the contributions of their team members, the Company stayed the course in 2017 to a successful operating performance.
Our Compensation Program for 2017 and Onward
After making several updates to our executive compensation program in 2016, aimed at furthering our goal of improved organization-wide performance and enhancing alignment of pay and performance, the committee determined that the program continues to meet the Company’s objectives, and consequently did not make major changes in 2017. We continue to look to reward strong business performance with compensation that will attract, retain and motivate a highly qualified management team. As indicated in this Compensation Discussion and Analysis, we believe that this pay-for-performance link is an essential component of our compensation program.
The principal components of compensation under our executive compensation program are annual base salary, annual cash incentive awards and long-term incentive awards, which, in 2017, consisted of performance-based units, or PBUs, restricted stock units, or RSUs, and stock options. We use this mix of fixed and variable pay components with different payout forms (cash, stock and stock options) to reward annual and sustained long-term performance. These components afford the committee the appropriate mechanisms to reward management for Grace performance.


We base the measures that we use to assess our performance for purposes of determining annual cash incentive awards for executive officers on our annual operating plan goals, which are directly tied to the pay outcomes of our executive officers. For the 2017 AICP, we used the following metrics to quantify Company-level performance:
Adjusted EBIT (weighted 50%) — demonstrates our effectiveness at growing the Company profitably through our focus on value selling, manufacturing excellence,portfolio, strong strategic position, and operating cost productivity.
Adjusted Free Cash Flow (weighted 25%) — reflects how well we manage our business as a whole; including net sales and profit growth and the investment required to support that growth.
Adjusted Net Sales (weighted 25%) — emphasizes the importance of top-line growth in measuring our market segment performance and confirmation of our ability to earn the confidence and trust of our customers.
disciplined capital allocation. We use these Company-level metrics to measure the performance of our executive officers and key executives; however, for other participants in our AICP we weight metrics differently, as appropriate to their position.
Based on our 2017 business plan, and operational and growth initiatives, we believe these measures best reflect our abilityinvest to grow our businesses, profitably,improve our strategic position, and maximize operational efficiencymaintain our returns. At the business level, we focus on customers, innovation, growth and profitability. We invest in R&D and technology innovation to drive customer-focused, solution-oriented innovation, and we invest in the Grace Manufacturing System as the foundation of our operating excellence strategy. Linking and enabling all elements are great talent, high-performance culture, and integrated business management processes. Our ability to rigorously execute the Grace Value Model is a principal source of our competitive advantage and our financial performance.

Our Response to COVID-19 and Hurricanes Laura and Delta
While our business suffered the disruptions that many other companies experienced due to COVID-19, we believe we differentiated ourselves in proactively managing our business and protecting our great talent. In addition, we were also impacted by two hurricanes – including the most powerful hurricane to ever hit Southwest Louisiana. Hurricane Laura delivered a direct blow to our Lake Charles facility, the largest refining catalyst plant in the world. Less than six weeks later, Hurricane Delta affected the same region again.
The following table highlights some of the actions taken in response to COVID-19 and the hurricanes:

Financial Performance
At the beginning of 2020, we were well positioned to deliver our financial outlook for the year. While we encountered significant obstacles presented by the COVID-19 pandemic and Gulf Coast hurricanes, we delivered a very strong finish to 2020, executing well in a challenging environment. We stayed focused on our growth strategy, leveraging our number one market positions, strong cash flow. They also allow usflow and customer-focused sustainability strategy. Grace achieved these results by taking decisive actions early in 2020 as the pandemic began to provide meaningful incentivesaffect economies around the world, and by successfully navigating the U.S. Gulf Coast hurricanes. We immediately lowered capital spending, improved working capital and reduced operating costs to improve our cash flow for the year. While we have not yet fully recovered from the economic effects of the pandemic, it is clear that our businesses are rebounding with momentum.
We remain focused on executing our profitable growth strategy and managing our company for the long-term. We have strong leadership positions in end-markets that are competitivecritical to consumers and the global economy and have continued to invest in these positions during the pandemic to ensure that we capture growth as our end markets recover. In recent years, we’ve taken meaningful steps to strengthen our portfolio and accelerate our growth by investing in our industry, which we believe encourages our executivespolyolefin catalyst, specialty silica and pharmaceutical end markets. These investments position Grace well for future growth to drive sustainedcreate long-term value for shareholders.
We achieved the following results and long-term stockholder value. The committee recognizescompared with the importance of strong earnings and cash generation as critical to Grace’s strategic plans, while also seeking to stress the importance of top-line sales growth. Accordingly,prior year for four key performance metrics that the committee uses Adjusted EBIT as the most heavily-weighted factor, with in compensation determinations:
Adjusted Net Sales weighted equally1 of $1,734.5 million decreased 12.4%, with Adjusted Free Cash Flow as performance measures.weak demand for catalysts used to produce transportation fuels partially offset by solid customer demand for our high-value petrochemical catalysts and process technology solutions and our silicas and pharmaceutical technologies;
During 2017, our LTIP grants consisted of three components: PBUs (50% of LTIP value), restricted stock units (25% of LTIP value) and stock options (25% of LTIP value). The PBUs consist of a target award of shares that can be increased, decreased, or forfeited based on Grace performance over a three-year performance period as compared to baseline performance during the year prior to the performance period. The number of performance-based unit shares to be paid out based upon EPS targets is subject to adjustment, up or down, by a factor of 25% if relative Total Shareholder Return for the three-year performance period is above the 75th percentile or below the 25th percentile of the Russell 1000 Index, respectively, subject to a maximum funding percentage. The PBUs "cliff vest" after the completion of the three-year performance period. The restricted stock units vest in three equal annual installments and will be settled within 60 days of those vesting dates. The stock options vest in three equal annual installments and have a five-year term from the grant date.
Notably, there was no 2015-2017 PBU performance period due to the announcement in 2015 of the separation. We did not believe that a three-year performance period based on Grace’s 2014 performance was appropriate given this transaction. Accordingly, we selected RSUs as the stock component of the 2015 LTIP Awards. As a result, we did not set a three-year performance goal and we granted RSUs instead of PBUs. This was a non-recurring action in connection with the separation and we returned to performance awards for the 2016-2018 cycle.
PBUs are designed to align leadership focus with our expectations for the ongoing success of our business and for driving long-term stockholder value. Specifically, the value of an individual performance-based unit award at vesting is based upon the:
Individual’s performance-based unit target share amount;
Growth in our LTIP Adjusted EPS over the three-year performance period;
Total Shareholder Return (or "TSR") for the three-year performance period as compared to a similar figure for the Russell 1000 Index; and


Value of Grace common stock on the payout date.
The value of a restricted stock unit at vesting is equal to the value of Grace common stock at that time, and the value of stock options is directly related to the increase in value of our stock, so both restricted stock units and stock options provide direct alignment between the interests of our executive officers and stockholders.

Adjusted EBIT1 of $312.2 million declined 34.0%, primarily due to lower gross profit, an approximately $19 million impact from hurricane-related costs and lower income from our ART joint venture, partially offset by lower operating expenses;
Adjusted EPS1 of $2.64 decreased 39.7%, including hurricane-related costs of approximately $0.21 per share; and;
Adjusted Free Cash Flow1 was $236.9 million, down 4.2%, reflecting strong execution of cash and cost management actions in response to the pandemic.

Annual Say-On-Pay Vote Results and Shareholder Engagement
At our annual meeting in May 2020, approximately 99% of the shareholder votes cast supported our executive compensation program in an advisory “say-on-pay” vote. Based on its review and consideration of the 2020 shareholder advisory vote, the committee believes these results indicate strong support for our compensation policies and structure and confirm the importance of our maintaining a strong link between pay and performance in our compensation philosophy and market-best practices.

46    W. R. GRACE & CO.


The committee welcomes the continued input of shareholders. Each year, the Company engages with a broad set of shareholders on a wide range of topics including strategy, operations, financial results, and sustainability and social responsibility. The Company has also sought the input of shareholders on our executive compensation program by means of the annual advisory “say-on-pay” vote, or in specific discussions about “say-on-pay” or our compensation programs and policies.
Upcoming 2021 Long Term Compensation Program Design Changes
We continue to evolve our compensation program in response to shareholder feedback, our business strategy, evolving market expectations, and peer benchmarking data. For 2021, we are making the following changes to our long-term incentive program:
Eliminating stock options and basing long-term incentive compensation on an even mix (at target) of PBUs and RSUs
Updating our relative TSR performance group to the Russell 3000 Chemicals Sector, rather than the full Russell 1000 index as used in 2020 and prior awards, to improve the comparison of our performance against relevant peers
Implementing a narrow EPS target range for 2021-2023 PBUs only to allow for greater uncertainty in goal-setting given the current pandemic-affected business conditions
Lowering the threshold performance from 85% to 80% of target, aligned with market practice
We believe that these adjustments are in the best interests of shareholders and align well with evolving market expectations for executive compensation.

2020 Executive Compensation Elements, Targets and Results
The principal components of compensation under our executive compensation program are annual base salary, annual cash incentive awards, and long-term incentive awards, which, in 2020, consisted of PBUs, RSUs, and stock options. We use this mix of fixed and variable pay components with different payout forms (cash, full-value stock awards and stock options) to reward annual and sustained, long-term performance. These components afford the committee the appropriate mechanisms to reward management for Grace performance and align our executives’ interests with those of our shareholders. We continuously evaluate best practices and market data to ensure alignment between pay and performance in our compensation plan design.
Base Salary
The committee reviews base salaries and market movement for executive officers annually, but also when roles change significantly. The committee considers individual performance, achievement of individual strategic objectives, changes in the breadth or scope of responsibilities, and its review of competitive compensation information described above.

Annual Incentive Compensation
The AICP is a cash-based, pay-for-performance incentive plan. Its purpose is to motivate and reward upper- and middle-level employees, including executive officers, for their contributions to our performance.
In 2020 prior to the pandemic, the AICP was based on earnings, cash generation, and revenue performance metrics, with the belief that those metrics closely aligned with short-term milestones in the Company’s strategy to achieve long-term value creation. Consistent with the 2019 AICP, the 2020 AICP used the following metrics to quantify performance:
Adjusted EBIT (weighted 50%) — demonstrates our effectiveness at growing the Company profitably through our focus on value selling, manufacturing excellence, and operating cost productivity.
Adjusted Net Sales (weighted 25%) — emphasizes the importance of top-line growth in measuring our market segment performance and confirmation of our ability to earn the confidence and trust of our customers.
Adjusted Free Cash Flow (weighted 25%) — reflects how well we manage our business as a whole; including net sales and profit growth and the investment required to support that growth.
The committee established 2020 AICP targets in February 2020 prior to the pandemic, based on the performance targets in our 2020 annual operating plan and after considering the general economic environment in which we expected to be operating during the year.
Payouts under the AICP are determined using the following process:

In setting the actual amount of the AICP incentive pool, the committee has discretion to adjust the performance objectives, adjust the calculation of each performance measure, or adjust the size of the AICP incentive pool irrespective of the achievement of performance objectives in consideration of unforeseeable or one-time events occurring during the course of the year.
The 2020 AICP target percentages for our NEOs remained the same as the end of 2019.

2020 AICP Performance Targets (For results in these three AICP target categories, see further below.)
The amount of the AICP incentive pool is the sum of the amounts funded in the Adjusted EBIT Pool, the Adjusted Free Cash Flow Pool, and the Adjusted Net Sales Pool. The funding of each pool is determined independently by reference to the Adjusted EBIT Target, Cash Target and Sales Target set forth in the Grace annual operating plan for the one-year performance period as follows:

Leadership Team Actions and Individual NEO Contributions to Value Delivered
Our executive team remained focused on employee safety and well-being, meeting our customers’ expectations and protecting shareholder value despite the challenges imposed by the COVID-19 pandemic and Gulf Coast Hurricanes. In early 2021, the Board and the committee evaluated each NEO’s performance in the response to COVID-19 and Hurricanes Laura and Delta, and their contributions towards managing the pandemic, meeting customer and shareholder needs, delivering financial results, advancing the Grace Value Model, managing human capital risk, promoting diversity and reinforcing our inclusive culture, and taking actions to manage our environmental footprint.
Our executives demonstrated strong leadership, working hard to ensure the safety and well-being of our employees while proactively managing our business. In determining AICP payouts to the NEOs in respect of 2020 performance,

51    W. R. GRACE & CO.


considerations made by the Board and the committee focused on the NEOs’ continued leadership in the face of internal and external challenges and included:
Immediate implementation of Grace’s global pandemic response plan designed to ensure employee health and safety and continuity of our business and manufacturing operations. Successful execution of our business continuity plan resulted in no customer disruptions as a result of the pandemic, a seamless transition to a remote work environment for nearly half of our employees, a new technology platform to support virtual customer business requirements and global communication, and the development of worksite safety protocols to protect our essential employees onsite.
A proactive response to maximize cash flow, including lower capital spending, improved working capital, and reduced operating costs. This organizational priority was reinforced across the company by resetting the AICP metric below the Leadership Team to focus solely on adjusted free cash flow. As a result of these actions and our collective focus, we delivered adjusted free cash flow at more than 95% of 2019 levels and remain well placed for future growth and investments.
The safe and successful launch of two significant capacity expansions which maintain our growth momentum and strong strategic position.
A quick, effective and comprehensive response following Hurricanes Laura and Delta, focused on supporting our affected employees, promptly and safely restoring our manufacturing operations and minimizing the impact experienced by our customers.
A commitment to our employees who worked tirelessly this year, with no layoffs and limited furloughs, no salary reductions, participation in a revised AICP which paid at an average of 71% of target (excluding our CEO and his Leadership Team), continued investments in employee development and the hiring of critical talent. This resulted in exceptionally high levels of engagement and productivity during the pandemic, ensuring we were able to meet the needs of our customers and that we are positioned well for future growth with a committed workforce.
As noted above, the committee approved the 2020 AICP goals in February 2020. Upon reviewing the plan during the year, the committee accepted that the performance goals no longer aligned with Grace’s operating plan given the impact of COVID-19 and Hurricanes Laura and Delta, and with continued uncertainty of COVID-19 no changes would be made to the pre-pandemic metrics or plan design for the CEO and his Leadership Team. Instead performance would be assessed holistically at year-end with consideration given to the application of discretion to provide appropriate payouts to participants.
In February 2021, the committee evaluated the formulaic AICP payout based on the goals approved in February 2020 and determined that the result did not fully represent the results that the executive team had delivered. After careful consideration of the above factors, the committee determined with the advice of its independent compensation consultant, it was appropriate to apply discretion to increase payouts from 16% of target to an average of approximately 60% of target for the CEO and his Leadership Team (including all NEOs) based on their individual contributions. The committee believed that these payouts, which remained both below target and below the payouts made to the broader employee population, were more appropriate reflections of both collective and individual NEO performance delivered during the year.
The following table describes the calculations for the AICP payout for each NEO, with the Individual Performance Adjustment reflecting the committee’s upward discretionary adjustment to AICP payouts:

Long-Term Incentive Compensation
Our Long-Term Incentive Plans, or LTIPs, are designed to motivate and reward LTIP participants, including our NEOs, for their contributions to our performance over a multi-year period, align their financial interests with those of our shareholders, and guide their behavior accordingly by making a significant portion of their total compensation variable and dependent upon our sustained financial performance. The goals of the LTIP are long-term operational excellence, increased quality of earnings, and shareholder value creation.
The target value of the LTIP award for each LTIP participant, with the exception of the CEO, was determined by the committee based on the recommendation of the CEO. The target value of the CEO’s LTIP award was determined by the committee without recommendation from the CEO. These target award values were determined by reviewing current market compensation data (as discussed above), historical long-term incentive target values, the level of dilution represented by outstanding equity awards, and internal pay equity considerations. These grant award values were determined in February 2020, before the breadth and depth of the effects of the pandemic were generally understood by the marketplace.
Set forth below is a discussion of our 2020 LTIP grants, followed by information on our 2018-2020 PBU performance period.
2020 LTIP Grants
During 2020, our LTIP grants consisted of three components: PBUs, RSUs, and stock options. The PBUs consist of a target award of shares that can be increased, decreased, or forfeited based on Grace’s results over a three-year performance period as compared to baseline performance during the year prior to the performance period. The number of PBU shares to be paid out is based upon EPS growth targets, subject to adjustment, up or down, by a factor of 25% if relative TSR for the three-year performance period is above the 75th percentile or below the 25th percentile of the Russell 1000 Index, respectively, subject to a maximum funding percentage. The PBUs “cliff vest” after the completion of the three-year performance period. The RSUs vest in three equal annual installments and will be settled within 60 days of each applicable vesting date. The stock options vest in three equal annual installments beginning on the first anniversary of the grant and have a ten-year term from the grant date.
LTIP grants for 2020 consisted of three components:
PBUs (approximately 50% of 2020 LTIP Value);
RSUs (approximately 25% of 2020 LTIP Value); and
Stock Options (approximately 25% of 2020 LTIP Value).
Grants for the 2020 LTIP were made on February 27, 2020, before the breadth and depth of the effects of the pandemic were understood.

53    W. R. GRACE & CO.


2020-2022 PBUs
The PBUs are share-denominated and the actual number of shares earned by an NEO can vary based on the achievement of specified business performance objectives. The value of the PBUs also varies based on the value of our stock and the amount of dividends paid on that stock. Accordingly, PBUs align leadership focus with our expectations for the ongoing success of our business and for increasing long-term shareholder value. Specifically, the amount of an individual payout under a 2020 PBU award is based upon:
the individual’s PBU target share amount;
the growth in our LTIP Adjusted EPS over the three-year performance period;
the TSR for the three-year performance period as compared to the Russell 1000 Index; and
the value of Grace common stock on the payout date.
Payouts to executives who are subject to the share ownership guidelines, including the NEOs, are payable in shares of common stock.
2020 LTIP Performance Target — LTIP Adjusted EPS
The committee selected Adjusted EPS as the primary performance measure for the PBUs, reflecting our focus on long-term operational excellence and quality of earnings. The committee believes that employing Adjusted EPS in the LTIP aligns internal leadership focus with the Board’s expectations for the ongoing success of our business and driving long-term shareholder value.
In determining cumulative LTIP Adjusted EPS growth, Adjusted EPS for the performance period may be adjusted in the discretion of the committee to eliminate the effect of changes in accounting, like our adoption of mark-to-market pension accounting, or significant changes in our business. In order to earn 100% of the target share amount, our LTIP Adjusted EPS for 2022 must reach $5.51, as reflected in the following table (Adjusted EPS at the end of fiscal year 2019 was $4.38):

2020 LTIP Performance Targets — Total Shareholder Return
The committee has selected TSR as the second performance measure for PBU awards, which provides enhanced alignment with actual shareholder value creation. We calculate TSR as the growth in stock price based upon 20-business-day average closing prices at the beginning and end of the performance period, plus dividends reinvested, compared to the same figure for the Russell 1000 Index. The number of PBU shares to be paid out based upon EPS targets as shown in the above table, is subject to adjustment, up or down, by a factor of 25% if relative TSR for the three-year period 2020-2022 is above the 75th percentile or below the 25th percentile of the Russell 1000 Index, respectively, subject to maximum funding of 200%. The committee chose the Russell 1000 Index in 2016 as it is a broad representation of similarly-sized companies including a majority of the Company’s peers.

We do not permit option repricing without stockholder approvalBelow 25th PercentileWe do not guarantee annual salary increasesDecrease of 25% of PBU Award

RSUs
RSUs represent approximately 25% of the value of our 2020 LTIP awards. The value of an RSU is directly related to the value of Grace common stock, so RSUs provide direct alignment between the interests of our executive officers and shareholders. RSUs granted in 2020 vest in three equal installments beginning on the anniversary of the grant date, generally subject to continued employment of the holder of the RSUs. Payments in respect of RSUs are made in shares of common stock.
Stock Options
Stock options represent approximately 25% of the value of our 2020 LTIP awards. The value of stock options is directly related to the increase in the value of our stock, so stock options provide direct alignment between the interests of our executive officers and shareholders. In determining the value of stock option awards, the committee uses an analysis of stock option value based on an adjusted Black-Scholes option pricing model and reviews this analysis with WTW. The committee approved the stock option grants included in the 2020 LTIP on February 27, 2020. The exercise price of the stock options was $55.405 which was the average of the high and low trading prices of Grace common stock on the NYSE on February 27, 2020. The term of the stock options is ten years and they vest over three years in equal annual installments, generally subject to the continued employment of the holder of the stock options.
Effect of Dividends on LTIP Awards
Following common market practice, the committee approved “dividend equivalent” accruals for holders of unvested RSUs and PBUs (which would be paid to holders only following vesting of the underlying award). Dividend equivalents accrue quarterly (based on target levels, in the case of PBUs) throughout the vesting period on all unvested PBUs and RSUs. In the case of PBUs we then adjust these dividend equivalents for actual Company performance (financial results) at the end of the performance period to correspond with the number of PBUs earned. In the event an employee leaves the Company before dividend equivalents are paid, for retirement, disability, or voluntary/involuntary termination, proration rules would apply to the dividend equivalents and any resulting unvested dividends would be forfeited. We do not provide dividend equivalents for stock option awards.
2018-2020 Long-Term Incentive Compensation Plan (or “2018 LTIP”) — PBUs
PBUs represented approximately 50% of the value of our 2018 LTIP awards. The PBUs are share-denominated and the actual number of shares earned by the NEOs in respect of the 2018 PBUs was determined based on the achievement of specified business performance objectives through December 31, 2020. Specifically, the realized value of an individual payout under a 2018 PBU award was based upon:
the individual’s PBU target share amount;

55    W. R. GRACE & CO.


the growth in our LTIP Adjusted EPS over the three-year performance period;
the TSR for the three-year performance period as compared to the Russell 1000; and
the value of Grace common stock on the payout date.
Payouts to the NEOs in respect of PBUs are made in shares of Grace common stock. The three-year EPS targets are set taking into account anticipated repurchases by the Company of its common stock; the committee has discretion to adjust for share repurchases above or below such anticipated levels.
2018 LTIP Performance Target — LTIP Adjusted EPS
The committee selected Adjusted EPS as the primary performance measure for the 2018 PBUs, reflecting our focus on long-term operational excellence and quality of earnings. The Adjusted EPS targets were reflective of a baseline Adjusted EPS of $3.36. In order to earn 100% of the target share amount, our cumulative annual LTIP Adjusted EPS growth from the 2017 baseline performance to 2020 actual performance had to reach $4.75 (approximately 141% of the $3.36 baseline amount), as reflected in the following table:

2018 LTIP Performance Target — TSR
The committee selected TSR as the second performance measure for 2018 PBU awards, which provided enhanced alignment with actual shareholder value creation. We calculate Total Shareholder Return as the growth in stock price between the first and last business day of the performance period plus dividends reinvested compared to the same figure for the Russell 1000 Index. The number of PBU shares to be paid out based upon EPS targets as shown in the above table was subject to adjustment, up or down, by a factor of 25% if relative TSR for the three-year period 2018-2020 is above the 75th percentile or below the 25th percentile of the Russell 1000 Index, respectively, subject to a maximum funding percentage of 200. The committee chose the Russell 1000 Index as it is a broad representation of similarly-sized companies, including a majority of the Company’s peers.
2018-2020 LTIP Adjusted EPS and Total Shareholder Return Results and 2018-2020 PBU Payouts
Based on the final EPS results, the formulaic payout of the 2018-2020 PBUs was 0% based on the direct impact of COVID-19 on our 2020 performance. The committee believed that this result did not accurately reflect the achievements of the executive team over the performance period, and with the advice of its independent compensation consultant, explored ways to more effectively balance pay and performance alignment.
The committee determined that it was important to recognize the financial accomplishments that the executive team had achieved through the first two years of the performance period prior to the pandemic, while holding the executive team accountable for the Company’s financial performance in the final year of the period. The committee also determined that it was important to hold the executive team accountable for relative shareholder value creation across the full performance period. The committee concluded that it was appropriate to bifurcate the three-year performance period to reflect the unanticipated impact of COVID-19.

56    W. R. GRACE & CO.


Through bifurcating the performance period, the committee believed the adjusted award enabled appropriate recognition of the above target performance delivered in the first two years of the performance period. The first period included 2018 and 2019, and the second period related to 2020. The target opportunity was pro-rated for the two periods, with the 2018-2019 period having two-thirds of the original opportunity and 2020 having one-third. The relative TSR modifier, measured over the original three-year performance period, continued to have effect for the full award. The Adjusted EPS goal was not modified; rather, payout in respect of the 2018-2019 period was based on progress towards the pro-rated original 2020 goal.
gracegraphics0324211a.jpg
Achievement related to the adjusted award segment pertaining to 2018 and 2019 was assessed based on progress towards achieving the 2020 target goal, pro-rated for the length of the segment performance period.
The target goal of $4.75 for 2020 represented a $1.39 improvement in Adjusted EPS compared to 2017 Adjusted EPS of $3.36 (Adjusted EPS for 2017 of $3.40 was further adjusted downward by $0.04 for stock-based compensation changes driven by Accounting Standards Update 2016-09). In 2019, the Company achieved Adjusted EPS of $4.38, a $1.02 improvement over the 2017 Adjusted EPS baseline. This represented the Company achieving 73% progress towards the 2020 target by the end of 2019 ($1.02 two-year improvement divided by the $1.39 three-year improvement goal).
Awards are also subject to a relative TSR modifier which adjusts the payout depending on the Company’s stock price performance when compared to the Russell 1000 index. Given this measure is, by design, self-calibrating (given the fact the Company’s TSR peers were also affected by COVID-19 and other environmental impacts in 2020) the committee did not believe it was necessary to adjust for the impact of COVID-19. Our TSR performance for the three-year period relative to the constituents in the Russell 1000 over the same period was in the lowest quartile, resulting in an additional 25% reduction in the number of PBUs earned in accordance with our program design (in other words, the number of earned PBUs was multiplied by 75%).

Other Components and Features of our Executive Compensation Program
Pension Plan/Supplemental Executive Retirement Plan
As described below under the caption “—Compensation Tables—Pension Benefits,” payments under our tax-qualified pension plan are calculated using annual compensation, including base salary and AICP awards, and years of credited Grace service. The committee has also implemented a Supplemental Executive Retirement Plan, generally referred to as a SERP, which applies to approximately 50 executive employees, including the NEOs whose annual compensation exceeds the amount that can be taken into account for purposes of calculating benefits under tax-qualified pension plans. Under this plan, each such employee will receive the full pension to which that employee would be entitled in the absence of the limitations described above and other limitations imposed under federal income tax law. The SERP is unfunded and is not qualified for tax purposes. The defined benefit pension plan and SERP have been closed to new entrants since January 1, 2017. Furthermore, in January 2021, Grace announced both plans will be frozen as of December 31, 2024 and as of January 1, 2025, all participants will be moved to a defined contribution retirement plan already in place for new hires as of January 1, 2017.
Savings and Investment Plan/Replacement Payment Plan
We generally offer a tax-qualified 401(k) Savings and Investment Plan, or S&I Plan, to employees under which they may save a portion of their annual compensation in investment accounts on a pre- or post-tax basis. During 2020, we matched 100% of employee savings under the S&I Plan up to 6% of the employee’s base salary and annual incentive compensation. The committee believes that a 401(k) plan with a meaningful Company match is an effective recruiting and retention tool for our employees, including our NEOs. The committee has also implemented

58    W. R. GRACE & CO.


an S&I Plan Replacement Payment Plan that currently applies to approximately 45 executive employees, including the NEOs, whose annual compensation exceeds the amount that can be taken into account for purposes of calculating benefits under tax-qualified savings plans, including the S&I Plan. Under the Replacement Plan, each such employee will receive the full matching payments to which that employee would be entitled in the absence of the limitations described above and other limitations imposed under federal income tax law.
Executive Personal Benefits
The committee believes that executive personal benefits should be limited. Executive officers, including the NEOs, are eligible to participate in an executive physical examination program that offers executives an annual comprehensive physical examination. Our CEO has access to corporate aircraft for reasonable personal travel and would be responsible for paying income taxes on the value of such travel as determined by the Internal Revenue Service.
Change in Control Severance Agreements
As described below under the caption “—Compensation Tables—Termination and Change in Control Arrangements,” we have entered into change in control severance agreements with each of the NEOs. We base the provisions in these agreements on competitive practice and design them to ensure that the NEOs’ interests remain aligned with the interests of our shareholders if a change in control occurs. Payments under these agreements are triggered by the involuntary termination of the executive officer’s employment without cause (including constructive termination caused by a material reduction in his or her authority or responsibility or by certain other circumstances) following a change in control, commonly referred to as a “double-trigger” arrangement. A change in control situation often undermines an executive officer’s job security, and it is to our benefit and our shareholders’ benefit to encourage our executive officers (including the NEOs) to seek out beneficial transactions and to remain employed through the closing of any transaction, even though their future employment at Grace may be uncertain. The change in control severance agreements are designed to reinforce and encourage the continued attention and dedication of the NEOs to their assigned duties without distraction in the face of potentially adverse circumstances arising from the possibility of a change in control of Grace. Certain terms of these agreements are described below under the caption “—Compensation Tables—Potential Payments Upon Termination or Change in Control.”
Severance Arrangements
Grace maintains the Severance Plan for Leadership Team Officers of W. R. Grace & Co. (the “Executive Severance Plan”), which provides that, if the employment of an executive officer (including our NEOs) is terminated without cause without a change in control, he or she will be entitled to cash severance equal to the sum of his or her base salary and target bonus (two times the sum, in the case of the CEO). The Executive Severance Plan also provides that, upon a termination without cause not due to a change in control, an executive officer will be entitled to a prorated annual bonus for the year of termination if he or she has completed at least three months of employment in the applicable year. Payments under the Executive Severance Plan are contingent upon the executive officer’s execution and non-revocation of a release of claims and non-compete and non-solicitation of employees covenants, in favor of Grace. We designed our severance arrangements to encourage and reinforce the continued attention and dedication of our executive officers to their assigned duties, without undue concern regarding their job security. See below under “—Compensation Tables—Potential Payments Upon Termination or Change in Control” and under “—Termination and Change in Control Arrangements” in that section.
Executive Salary Protection Plan
As described below under the caption “—Compensation Tables—Potential Payments Upon Termination or Change in Control,” our Executive Salary Protection Plan (“ESPP”) provides payments to our NEOs, or their respective beneficiaries, in the event of their disability or death prior to age 70 while employed by Grace. We designed the plan to encourage the continued attention and dedication of our executive officers (including our NEOs) to their assigned duties without undue concern regarding their ability to earn a living and support their families in the event of death or disability.

Vesting under the 2018 Stock Incentive Plan
Under the 2018 Stock Incentive Plan, subject to change in control provisions thereof, stock incentives shall vest no earlier than the first anniversary of the date the stock incentive is granted; provided, however, that, stock incentives that result in the issuance of an aggregate of up to 5% of the shares of Common Stock available under the Plan may be granted to any one or more NEOs without respect to such minimum vesting provisions and nothing therein shall preclude the committee from accelerating or maintaining the vesting of any stock incentives in connection with a named executive officer’s death, disability, retirement or other termination of Service.
Executive Compensation Program Philosophy, Objectives, and Processes
Alignment between Pay and Performance
The committee believes that the Company’s executive compensation program provides a strong linkage between pay and performance and is well-aligned with stockholdershareholder interests. Our measures of performance under our AICP and LTIP — earnings, cash flow, sales,Adjusted Net Sales, Adjusted EBIT, Adjusted Free Cash Flow, EPS and TSR, are accepted measures of financial success by the investment community, and similar measures are also are used by our peer companies in various forms of incentives. The committee sets targets for these measures based on the macroeconomic environment, competitive dynamics, and factors unique to the Company. The committee designs these targets which, if attained, represent excellent performance by the Company. If the Company achieves or exceeds these targets, the committee believes executives generally should be rewarded with higher payouts of awards, and if targets are not met, executives generally should receive lower or no awards.
Our CEO Pay At-A-Glance
Mr. Festa's total direct compensation (total compensation less pension changes and other annual compensation) for 2017 was $6,445,988, a decrease of 0.1% compared with the prior year. The chart below shows the components of pay awarded in 2017 compared with the prior year. For more details about the structure of Mr. Festa's compensation, see "—Compensation Tables—Summary Compensation Table." Although Mr. Festa's total direct compensation decreased slightly year-over-year, his AICP payment was higher for 2017 due to the Company's operating performance, particularly 2017 AICP Adjusted Free Cash Flow and 2017 AICP Adjusted Net Sales. The Fair Market Value of Mr. Festa’s 2016 RSU grants included $125,437 in incremental fair value due to the adjustment of a previously granted RSU award as a result of the separation in 2016. If the latter were excluded, Mr. Festa's compensation increased approximately 2% year-over-year.

Overview of Our Executive Compensation Program and Philosophy
Key Objectives
The key objectives of the Grace executive compensation program for executive officers are to incentivize and motivate our executive officers to improve our performance, deliver our growth plan, and increase stockholdershareholder value; and to enable us to compete effectively with other firms in attracting, motivating and retaining executives. We designed the incentive compensation portion of the program to closely align the financial interests of our executive officers with those of our stockholders.shareholders. Because executive officers have a substantial ability to influence business success, we believe that the portion of compensation that is at-risk based on organization-wide performance should increase as the level of responsibility increases.
We also expect the executive compensation program to be effectuatedapplied consistently with our culture of ethical conduct, personal integrity, and compliance with both our policies and applicable law. We requireexpect our executive officers to set anlead by example, formodeling our employees and our other business associates in emphasizing the Grace Core Values in their daily business conduct. The Grace Core Values consist of a commitment to teamwork, performance, integrity, speed and innovation, which, with our overall commitment to safety, are the foundation of our corporate culture.


StockShare Ownership Guidelines
Our Board has designed and implemented stockshare ownership guidelines to align the long-term financial interests of our directors and executive officers with the long-term interests of our stockholders.shareholders. The guidelines are set forth under "Proposal“Proposal One—Election of Directors—Corporate Governance—StockShare Ownership Guidelines."Guidelines” and are incorporated herein by reference.
Annual Say-On-Pay Vote Results
At our annual meeting in May 2017, approximately 90% of the stockholder votes cast supported our executive compensation program in an advisory “say-on-pay” vote. Based on its review and consideration of the 2017 stockholder advisory vote, the committee believes these results indicate strong support for our compensation policies and confirm the importance of our maintaining a strong link between pay and performance in our compensation philosophy and market-best practices. The committee welcomes the continued input of stockholders by means of the annual advisory "say-on-pay" vote and the Company remains committed to stockholder engagement. (See "Proposal One—Election of Directors—Corporate Governance—Stockholder Engagement.")


How We Set Compensation Elements and Target Mix
Our Board of Directors has delegated to the committee, the authority for approving and administering the compensation program for executive officers (including the "named executive officers"NEOs in the Summary Compensation Table set forth under "—“—Compensation Tables"Tables”) to the committee.. Our Board has appointed all of the independent members of our Board to serve as members of the committee.

Compensation Benchmarking
In order to gauge market compensation levels and practices, the committee has retained the services of Willis Towers Watson, anWTW, a leading independent risk managementglobal advisory, broking and human resources consulting firm.solutions company. Periodically, the committee consults with Willis Towers WatsonWTW for an assessment of our executive officer compensation program relative to the competitive market.
The committee, with the assistance of WTW, has selected the companies below as our compensation peer group based upon their industry (those being chemicals, materials and specialty chemicals), size and global scope, revenues, profitability, market capitalization, market for talent, and the availability of public information regarding their compensation practices. The committee relies upon the compensation data gathered from the peer group as well as published broad industry survey data, reflecting the chemicals and general manufacturing industries, to represent the competitive market for executive talent for our executive officers, and does not focus on any specific data or benchmark for guidance when making pay decisions. The committee reviews the composition of our compensation peer group regularlyannually to ensure that it remains suitable and appropriate.appropriate and removes companies that are no longer public entities.

Also, the committee oversees the development of succession plans for the CEO and the other named executive officers.officer including our NEOs. Our human resources department and legal services group provide advice and legal and administrative assistance to aid the committee in meeting its responsibilities.
The committee reviews the distribution of peer group pay practices and broad industry data and determines the appropriate positioning of each executive officer'sofficer’s compensation based on several factors, including:

The committee’s compensation philosophy is to attract, retain and motivate employees to deliver results and increase shareholder value, performing in the best interests of the Company and its shareholders. The committee conducts an annual evaluation of each executive officer'sreviews compensation policies and plans to ensure that this philosophy is supported and that such policies and plans allow the Company to compete effectively with other firms in attracting, motivating and retaining the talent required.
Each year, the committee evaluates the leadership ability, business experience, technical skill, and potential to contribute to Grace’s overall performance.performance, of each executive officer (including our NEOs). In addition, since the number of executive officers is small, the committee is able to spend considerable time with each executive officer outside committee meetings, so the committee members are able to develop strong personalholistic views of each executive officer’s performance and potential. The committee also reviews each executive officer'sofficer’s existing compensation. This information, presented in the form of a "tally“tally sheet," reflects all compensation payable or potentially payable to each executive officer under our compensation program. For each executive officer, the committee reviews the tally sheet, the peer group information, and broad industry data to provide context to the compensation decision.decisions. The committee then reviews the recommendation of the CEO, as discussed below, solely with respect to the other

executive officers, and makes the compensation determination based on its individual evaluation of each executive officer.


The committee'scommittee’s process for determining the compensation of the CEO is similar to the process it applies to other executive officers. The committee reviews and approves corporate goals and objectives used in determining the compensation of the CEO. The committee evaluates the CEO'sCEO’s performance in light ofconsidering those goals and objectives as well as market data and has sole authority to determine the CEO'sCEO’s compensation based on this evaluation. The CEO plays no part in the committee'scommittee’s deliberations concerning, or approval of, histhe CEO’s own compensation. The committee believes the CEO'sCEO’s compensation should be higher than the compensation of other executive officers because the CEO is uniquely positioned to influence all aspects of our operations and performance and the resulting return to our stockholders.shareholders. In addition, the committee believes that a competitive compensation package that aligns the interests of the CEO with Grace's stockholdersGrace’s shareholders is the most effective way to incentivize the CEO and maximize companyCompany performance. The committee'scommittee’s view is consistent with the practices of the compensation peer group companies and the broad industry data that itthe committee has reviewed.reviewed, as described in greater detail in the section below titled “Role of the Compensation Consultant.”
RoleEffect of Dividends on LTIP Awards
Following common market practice, the committee approved “dividend equivalent” accruals for holders of unvested RSUs and PBUs (which would be paid to holders only following vesting of the Chief Executive Officer
The CEO proposes compensationunderlying award). Dividend equivalents accrue quarterly (based on target levels, in the case of PBUs) throughout the vesting period on all unvested PBUs and RSUs. In the case of PBUs we then adjust these dividend equivalents for actual Company performance (financial results) at the other executive officers. The CEO bases his recommendations for the other executive officers on his personal reviewend of the factors considered by the committee, as described above. Although the committee affords the CEO’s recommendations significant weight, the committee retains full discretion when determining executive officer compensation. Although not a member of the committee, the CEO attends committee meetings and participates in committee deliberations regarding compensation levels for the other executive officers. The CEO is excused from deliberations regarding his own compensation and from the "executive session" portion of each meeting when the committee meets alone or alone with its outside advisors. The CEO is also excused when the committee meets separately with internal advisors from our human resources group.
Role of the Compensation Consultant
In orderperformance period to add rigor in the process of setting executive officer compensation and to inform the committee of market trends, the committee has engaged the services of Willis Towers Watson to analyze our executive compensation structure and plan designs, and to assess whether our compensation program is competitive and supports the committee’s goal to align the interests of our executive teamcorrespond with the interestsnumber of our stockholders.
Specific services provided by Willis Towers Watson in 2017 included:
participation in selected committee meetings;
review of our pay-for-performance alignment;
review of risk factors associated withPBUs earned. In the design and administration ofevent an employee leaves the Company's executive compensation program;
review of companies included in the compensation peer group;
preparation of market compensation dataCompany before dividend equivalents are paid, for executives and outside directors;
review of the CEO’s compensation recommendations for the other named executive officers;
presentation of recommendations for the CEO’s compensationretirement, disability, or voluntary/involuntary termination, proration rules would apply to the committee;dividend equivalents and any resulting unvested dividends would be forfeited. We do not provide dividend equivalents for stock option awards.
assessment of the share usage under our long-term incentive plan versus the peer group;
advice on incentive compensation plan design;
advice on current market trends and practices; and
review of compensation disclosure.
We expect Willis Towers Watson and our executive officers, including our CEO, Chief Human Resources Officer and General Counsel, and their respective subordinates, to meet, exchange information and otherwise cooperate in the performance of their respective duties outside committee meetings.
During 2017, the Company paid fees to Willis Towers Watson for services rendered in respect of executive officer and director compensation in the amount of $194,632. In addition, management engaged Willis Towers Watson to provide additional services to the Company in an amount equal to


$374,122 during 2017. These services included human capital and broking, and data, surveys and technology.
The committee has the sole authority to approve the independent compensation consultant’s fees and terms of engagement. The committee annually reviews its relationship with Willis Towers Watson to ensure independence. The process includes a review of the services Willis Towers Watson provides, the quality of those services, and fees associated with the services during 2017 as well as consideration of the factors impacting independence that the NYSE rules require. In its review, the committee noted no conflicts of interest related to the work of Willis Towers Watson and has determined the consultant to be independent.
Application of the Compensation Program for 2017 Elements, Targets and Results
Base Salary
The committee generally reviews base salaries for executive officers annually, but also when roles change significantly. The committee takes into account individual performance, achievement of individual strategic objectives, changes in the breadth or scope of responsibilities, and its review of competitive compensation information described above. In 2017, the committee maintained base salaries for the named executive officers continuing in their positions at the 2016 levels, as set forth in the following table, since the committee determined that such compensation levels were competitive within our peer group. In keeping with the committee’s view that a substantial portion of executive compensation should be at risk, Mr. Festa has not had an increase in base salary since 2011.

Annual Incentive Compensation
The AICP is a cash-based, pay-for-performance incentive plan. Its purpose is to motivate and reward upper- and middle-level employees, including executive officers, for their contributions to our performance. The amount of an individual incentive award payment under the AICP is based upon:
the individual's AICP target amount;
the funding of the AICP incentive pool based on our performance; and
the individual's personal performance.
The committee established 2017 AICP targets in February 2017, based on the performance targets in our 2017 annual operating plan and after considering the general economic environment in which we expected to be operating during the year.
In 2017, the committee emphasized earnings, cash generation, and revenue performance in setting the annual incentive compensation plan goals. Consistent with 2016, earnings remained weighted for half of the plan, reflecting an emphasis on margins and controlling costs. The committee viewed strong cash performance as critical to our strategic direction in 2017 and a key component in our future plans and consequently weighted cash generation at 25% for 2017. The committee also gave sales equal weight at 25% for 2017 to stress the importance of revenue growth.
For earnings, the committee used "Adjusted EBIT."


For cash generation, the committee used "Adjusted Free Cash Flow."
For revenue growth, the committee used "Adjusted Net Sales."
Adjusted EBIT demonstrates our effectiveness at growing the Company profitably through our focus on value selling, manufacturing excellence, and operating cost productivity. Adjusted Free Cash Flow reflects how well we manage our business as a whole; including net sales and profit growth and the investment required to support that growth. Adjusted Net Sales emphasizes the importance of top-line growth in measuring our market segment performance and confirmation of our ability to earn the confidence and trust of our customers.
In setting the actual amount of the Corporate AICP incentive pool, the committee has discretion to adjust the performance objectives, adjust the calculation of each performance measure or adjust the size of the AICP incentive pool irrespective of the achievement of performance objectives.
The 2017 AICP targets for our named executive officers remained substantially the same as in 2016.

2017 AICP Performance Targets (For results in these three AICP target categories, see below.)
The amount of the AICP incentive pool is the sum of the amounts funded in the Adjusted EBIT Pool, Adjusted Free Cash Flow Pool and the Adjusted Net Sales Pool. The funding of each pool is determined independently by reference to the Adjusted EBIT Target, Cash Target and Sales Target set forth in the Grace annual operating plan for the one-year performance period as follows:

Our 2017 AICP Adjusted Free Cash Flow and AICP Adjusted Net Sales were well above our 2017 annual operating plan, while our AICP Adjusted EBIT was 1% below plan. This aggregate performance resulted in 100% of the Corporate Target AICP Incentive Pool being funded, following a downward adjustment by exercise of committee discretion to reflect receipt of business interruption insurance proceeds that exceeded amounts forecast in our annual operating plan, as shown the following table:

Executive Officer Annual2018-2020 Long-Term Incentive Compensation Plan (EAICP)(or “2018 LTIP”) Funding of Payments PBUs
The Executive Officer Annual Incentive Compensation Plan, or EAICP, applicable to all executive officers, provides for performance-based incentives designed to meet the requirements for tax deductibility under Section 162(m) of the Tax Code. AICP payments to executive officers are funded from the EAICP incentive pool. The EAICP incentive pool is funded at 200% of the aggregate of the executive officers' AICP target awards if Grace meets the performance targets that the committee establishes for a specified year. In setting the actual amount of executive officers' AICP awards, the committee has the discretion to reduce, but not increase, the amount of the EAICP incentive pool and the amounts, based on the EAICP incentive pool, of individual AICP payments to executive officers. For 2017, the EAICP performance target was $150 million in Adjusted Free Cash Flow. Since actual Grace performance in respect of the Adjusted Free Cash Flow performance target was $274 million, the EAICP incentive pool was fully funded. The committee exercised its discretion to reduce actual awards to the named executive officers in line with AICP performance to the amounts reflected in the table below.
2017 AICP payments to the named executive officers are as set forth below:

Long-Term Incentive Compensation
Our Long-Term Incentive Plans, or LTIPs, are designed to motivate and reward LTIP participants, including our named executive officers, for their contributions to our performance over a multi-year period, align their financial interests with those of our stockholders, and guide their behavior accordingly by making a significant portion of their total compensation variable and dependent upon our sustained financial performance. We seek long-term operational excellence, quality of earnings and stockholder value creation. The target value of the LTIP award for each LTIP participant, with the exception of the CEO, was determined by the committee based on the recommendation of the CEO. The target value of the CEO’s LTIP award was determined by the committee. These target award values were determined by reviewing current market compensation data (as discussed earlier in this report), historical long-term


incentive target values, the level of dilutionPBUs represented by outstanding equity awards and internal pay equity considerations.
LTIP grants for 2017 consisted of three components:
Performance-Based Units (50%);
Restricted Stock Units (25%); and
Stock Options (25%).
2017-2019 Performance-Based Units (50% of 2017 LTIP Value)
Performance-based units, or PBUs, representapproximately 50% of the value of our 20172018 LTIP awards. The PBUs are share-denominated and the actual number of shares earned by a named executive officer can varythe NEOs in respect of the 2018 PBUs was determined based on the achievement of specified business performance objectives. The value of the PBUs also varies based on the value of our stock and the amount of dividends paid on that stock. Accordingly, PBUs align leadership focus with our expectations for the ongoing success of our business and for increasing long-term stockholder value.objectives through December 31, 2020.

2018 LTIP Performance Target — LTIP Adjusted EPS

In determining cumulative LTIPThe Adjusted EPS growth,targets were reflective of a baseline Adjusted EPS for the performance period may be adjusted in the discretion of the committee to eliminate the effect of changes in accounting, like our adoption of mark-to-market pension accounting, or significant changes in our business, like a significant acquisition or divestment.$3.36. In order to earn 100% of the target share amount, our cumulative annual LTIP Adjusted EPS for 2019 mustgrowth from the 2017 baseline performance to 2020 actual performance had to reach $3.80,$4.75 (approximately 141% of the $3.36 baseline amount), as reflected in the following table:

2017 LTIP Performance TargetsTotal Shareholder Return TSR
The committee has selected Total Shareholder ReturnTSR as the second performance measure for performance-based unit2018 PBU awards, which providesprovided enhanced alignment with actual stockholdershareholder value creation. We calculate Total Shareholder Return as the growth in stock price between the first and last business day of the performance period plus dividends reinvested compared to the same figure for the Russell 1000 Index. The number of performance-based unitPBU shares to be paid out based upon EPS targets as shown in the above table iswas subject to adjustment, up or down, by a factor of 25% if relative Total Shareholder ReturnTSR for the three-year period 2017-20192018-2020 is above the 75th percentile or below the 25th percentile of the Russell 1000 Index, respectively, subject to a maximum funding percentage of 200. The committee chose the Russell 1000 Index as it is a broad representation of similarly-sized companies, including a majority of the Company'sCompany’s peers.
2018-2020 LTIP Adjusted EPS and Total Shareholder Return Results and 2018-2020 PBU Payouts
Based on the final EPS results, the formulaic payout of the 2018-2020 PBUs was 0% based on the direct impact of COVID-19 on our 2020 performance. The committee believed that this result did not accurately reflect the achievements of the executive team over the performance period, and with the advice of its independent compensation consultant, explored ways to more effectively balance pay and performance alignment.
The committee determined that it was important to recognize the financial accomplishments that the executive team had achieved through the first two years of the performance period prior to the pandemic, while holding the executive team accountable for the Company’s financial performance in the final year of the period. The committee also determined that it was important to hold the executive team accountable for relative shareholder value creation across the full performance period. The committee concluded that it was appropriate to bifurcate the three-year performance period to reflect the unanticipated impact of COVID-19.

56    W. R. GRACE & CO.


Through bifurcating the performance period, the committee believed the adjusted award enabled appropriate recognition of the above target performance delivered in the first two years of the performance period. The first period included 2018 and 2019, and the second period related to 2020. The target opportunity was pro-rated for the two periods, with the 2018-2019 period having two-thirds of the original opportunity and 2020 having one-third. The relative TSR modifier, measured over the original three-year performance period, continued to have effect for the full award. The Adjusted EPS goal was not modified; rather, payout in respect of the 2018-2019 period was based on progress towards the pro-rated original 2020 goal.
gracegraphics0324211a.jpg
Achievement related to the adjusted award segment pertaining to 2018 and 2019 was assessed based on progress towards achieving the 2020 target goal, pro-rated for the length of the segment performance period.
The target goal of $4.75 for 2020 represented a $1.39 improvement in Adjusted EPS compared to 2017 Adjusted EPS of $3.36 (Adjusted EPS for 2017 of $3.40 was further adjusted downward by $0.04 for stock-based compensation changes driven by Accounting Standards Update 2016-09). In 2019, the Company achieved Adjusted EPS of $4.38, a $1.02 improvement over the 2017 Adjusted EPS baseline. This represented the Company achieving 73% progress towards the 2020 target by the end of 2019 ($1.02 two-year improvement divided by the $1.39 three-year improvement goal).
Awards are also subject to a relative TSR modifier which adjusts the payout depending on the Company’s stock price performance when compared to the Russell 1000 index. Given this measure is, by design, self-calibrating (given the fact the Company’s TSR peers were also affected by COVID-19 and other environmental impacts in 2020) the committee did not believe it was necessary to adjust for the impact of COVID-19. Our TSR performance for the three-year period relative to the constituents in the Russell 1000 over the same period was in the lowest quartile, resulting in an additional 25% reduction in the number of PBUs earned in accordance with our program design (in other words, the number of earned PBUs was multiplied by 75%).

Stock Options (25% of LTIP Value)
Stock options represent 25% of the value of our 2017 LTIP awards. The value of stock options is directly related to the increase in the value of our stock, so stock options provide direct alignment between the interests of our executive officers and stockholders. In determining the value of stock option awards, the committee uses an analysis of stock option value based on an adjusted Black-Scholes option pricing model and reviews this analysis with Willis Towers Watson. The committee approved the stock option grants included in the 2017 LTIP on February 23, 2017.

Other Components and Features of our Executive Compensation Program
Pension Plan/Supplemental Executive Retirement Plan
As described below under the caption “—Compensation Tables—Pension Benefits,” payments under our tax-qualified pension plan are calculated using annual compensation, including base salary and AICP awards, and years of credited Grace service. The termcommittee has also implemented a Supplemental Executive Retirement Plan, generally referred to as a SERP, which applies to approximately 50 executive employees, including the NEOs whose annual compensation exceeds the amount that can be taken into account for purposes of calculating benefits under tax-qualified pension plans. Under this plan, each such employee will receive the full pension to which that employee would be entitled in the absence of the stock optionslimitations described above and other limitations imposed under federal income tax law. The SERP is five yearsunfunded and is not qualified for tax purposes. The defined benefit pension plan and SERP have been closed to new entrants since January 1, 2017. Furthermore, in January 2021, Grace announced both plans will be frozen as of December 31, 2024 and as of January 1, 2025, all participants will be moved to a defined contribution retirement plan already in place for new hires as of January 1, 2017.
Savings and Investment Plan/Replacement Payment Plan
We generally offer a tax-qualified 401(k) Savings and Investment Plan, or S&I Plan, to employees under which they vest overmay save a portion of their annual compensation in investment accounts on a pre- or post-tax basis. During 2020, we matched 100% of employee savings under the S&I Plan up to 6% of the employee’s base salary and annual incentive compensation. The committee believes that a 401(k) plan with a meaningful Company match is an effective recruiting and retention tool for our employees, including our NEOs. The committee has also implemented

58    W. R. GRACE & CO.


an S&I Plan Replacement Payment Plan that currently applies to approximately 45 executive employees, including the NEOs, whose annual compensation exceeds the amount that can be taken into account for purposes of calculating benefits under tax-qualified savings plans, including the S&I Plan. Under the Replacement Plan, each such employee will receive the full matching payments to which that employee would be entitled in the absence of the limitations described above and other limitations imposed under federal income tax law.
Executive Personal Benefits
The committee believes that executive personal benefits should be limited. Executive officers, including the NEOs, are eligible to participate in an executive physical examination program that offers executives an annual comprehensive physical examination. Our CEO has access to corporate aircraft for reasonable personal travel and would be responsible for paying income taxes on the value of such travel as determined by the Internal Revenue Service.
Change in Control Severance Agreements
As described below under the caption “—Compensation Tables—Termination and Change in Control Arrangements,” we have entered into change in control severance agreements with each of the NEOs. We base the provisions in these agreements on competitive practice and design them to ensure that the NEOs’ interests remain aligned with the interests of our shareholders if a change in control occurs. Payments under these agreements are triggered by the involuntary termination of the executive officer’s employment without cause (including constructive termination caused by a material reduction in his or her authority or responsibility or by certain other circumstances) following a change in control, commonly referred to as a “double-trigger” arrangement. A change in control situation often undermines an executive officer’s job security, and it is to our benefit and our shareholders’ benefit to encourage our executive officers (including the NEOs) to seek out beneficial transactions and to remain employed through the closing of any transaction, even though their future employment at Grace may be uncertain. The change in control severance agreements are designed to reinforce and encourage the continued attention and dedication of the NEOs to their assigned duties without distraction in the face of potentially adverse circumstances arising from the possibility of a change in control of Grace. Certain terms of these agreements are described below under the caption “—Compensation Tables—Potential Payments Upon Termination or Change in Control.”
Severance Arrangements
Grace maintains the Severance Plan for Leadership Team Officers of W. R. Grace & Co. (the “Executive Severance Plan”), which provides that, if the employment of an executive officer (including our NEOs) is terminated without cause without a change in control, he or she will be entitled to cash severance equal to the sum of his or her base salary and target bonus (two times the sum, in the case of the CEO). The Executive Severance Plan also provides that, upon a termination without cause not due to a change in control, an executive officer will be entitled to a prorated annual bonus for the year of termination if he or she has completed at least three yearsmonths of employment in equal annual installments, generallythe applicable year. Payments under the Executive Severance Plan are contingent upon the executive officer’s execution and non-revocation of a release of claims and non-compete and non-solicitation of employees covenants, in favor of Grace. We designed our severance arrangements to encourage and reinforce the continued attention and dedication of our executive officers to their assigned duties, without undue concern regarding their job security. See below under “—Compensation Tables—Potential Payments Upon Termination or Change in Control” and under “—Termination and Change in Control Arrangements” in that section.
Executive Salary Protection Plan
As described below under the caption “—Compensation Tables—Potential Payments Upon Termination or Change in Control,” our Executive Salary Protection Plan (“ESPP”) provides payments to our NEOs, or their respective beneficiaries, in the event of their disability or death prior to age 70 while employed by Grace. We designed the plan to encourage the continued attention and dedication of our executive officers (including our NEOs) to their assigned duties without undue concern regarding their ability to earn a living and support their families in the event of death or disability.

Executive Compensation Program Philosophy, Objectives, and Processes
Alignment between Pay and Performance
The committee believes that the Company’s executive compensation program provides a strong linkage between pay and performance and is well-aligned with shareholder interests. Our measures of performance under our AICP and LTIP — Adjusted Net Sales, Adjusted EBIT, Adjusted Free Cash Flow, EPS and TSR, are accepted measures of financial success by the investment community, and similar measures are also used by our peer companies in various forms of incentives. The committee sets targets for these measures based on the macroeconomic environment, competitive dynamics, and factors unique to the Company. The committee designs these targets which, if attained, represent excellent performance by the Company. If the Company achieves or exceeds these targets, the committee believes executives generally should be rewarded with higher payouts of awards, and if targets are not met, executives generally should receive lower or no awards.
Key Objectives
The key objectives of the Grace executive compensation program for executive officers are to incentivize and motivate our executive officers to improve our performance, deliver our growth plan, and increase shareholder value; and to enable us to compete effectively with other firms in attracting, motivating and retaining executives. We designed the incentive compensation portion of the program to closely align the financial interests of our executive officers with those of our shareholders. Because executive officers have a substantial ability to influence business success, we believe that the portion of compensation that is at-risk based on organization-wide performance should increase as the level of responsibility increases.
We also expect the executive compensation program to be applied consistently with our culture of ethical conduct, personal integrity, and compliance with both our policies and applicable law. We expect our executive officers to lead by example, modeling our Grace Core Values in their daily business conduct. The Grace Core Values consist of a commitment to teamwork, performance, integrity, speed and innovation, which, with our overall commitment to safety, are the foundation of our corporate culture.
Share Ownership Guidelines
Our Board has designed and implemented share ownership guidelines to align the long-term financial interests of our directors and executive officers with the long-term interests of our shareholders. The guidelines are set forth under “Proposal One—Election of Directors—Corporate Governance—Share Ownership Guidelines” and are incorporated herein by reference.
How We Set Compensation — Elements and Target Mix
Our Board has delegated to the committee, the authority for approving and administering the compensation program for executive officers (including the NEOs in the Summary Compensation Table set forth under “—Compensation Tables”). Our Board has appointed all of the independent members of our Board to serve as members of the committee.

60    W. R. GRACE & CO.

Target Compensation Mix
As determined by the committee, and informed by market practices, our compensation mix at target (shown above for both our CEO and, collectively, for the other NEOs) is largely incentive-based. The charts further below include 2020 base salary, target AICP, and grant date fair values for the 2020 LTIP grants. The charts illustrate how the mix of target total direct compensation for our NEOs emphasizes incentive compensation, with a significant focus on long-term incentives tied to our long-term performance. Further, the charts indicate the high percentage of executive compensation that is “at-risk,” demonstrating the linkage of shareholder interests and executive officer performance goals.

Compensation Benchmarking
In order to gauge market compensation levels and practices, the committee has retained the services of WTW, a leading independent global advisory, broking and solutions company. Periodically, the committee consults with WTW for an assessment of our executive officer compensation program relative to the competitive market.
The committee, with the assistance of WTW, has selected the companies below as our compensation peer group based upon their industry (those being chemicals, materials and specialty chemicals), size and global scope, revenues, profitability, market capitalization, market for talent, and the availability of public information regarding their compensation practices. The committee relies upon the compensation data gathered from the peer group as well as published broad industry survey data, reflecting the chemicals and general industries, to represent the competitive market for executive talent for our executive officers, and does not focus on any specific data or benchmark for guidance when making pay decisions. The committee reviews the composition of our compensation peer group annually to ensure that it remains suitable and appropriate and removes companies that are no longer public entities.

When reviewing the appropriateness of including companies in our peer group based on revenues, we consider the total net sales of Advanced Refining Technologies LLC (or “ART”), our joint venture with Chevron Products Company, a division of Chevron U.S.A. Inc., given our significant managerial responsibilities in connection therewith. Net sales of ART, an unconsolidated affiliate in which we have a 50% interest, were $481.9 million during 2020. We also consider total ART net sales in survey benchmarking.

Contributions of the Committee, CEO and Consultant in our Executive Compensation Process
Role of the Compensation Committee
Pursuant to a delegation from our Board, the committee is responsible for reviewing and approving the compensation of all executive officers, including:
base salary
annual incentive compensation
long-term incentive compensation
employment agreements
severance arrangements
change in control agreements
any special or supplemental benefits not generally available to salaried employees
The committee oversees executive development and succession planning for the CEO and the other executive officers; reviews management’s goal setting process; identifies important year-over-year and multi-year targets; and commits the executive compensation program to a rigorous review annually. The committee reviews and approves all corporate goals and objectives used in determining the incentive compensation of each executive officer including our NEOs. Our human resources department and legal services group provide advice and legal and administrative assistance to aid the committee in meeting its responsibilities.
The committee reviews the distribution of peer group pay practices and broad industry data and determines the appropriate positioning of each executive officer’s compensation based on several factors, including:
the executive officer’s role and level of responsibility
the executive officer’s individual performance in that role
the need to attract, retain and motivate the talent required for world-class leadership
the economic and business environment in which Grace operates
the importance of the executive officer to Grace’s objectives and strategy
internal comparisons of pay and roles within the executive officer group;
legal and governance requirements and standards related to executive compensation, including internal pay equity with other salaried employees
with respect to executive officers other than the CEO, the CEO’s recommendation of appropriate compensation levels
The committee’s compensation philosophy is to attract, retain and motivate employees to deliver results and increase shareholder value, performing in the best interests of the Company and its shareholders. The committee reviews compensation policies and plans to ensure that this philosophy is supported and that such policies and plans allow the Company to compete effectively with other firms in attracting, motivating and retaining the talent required.
Each year, the committee evaluates the leadership ability, business experience, technical skill, and potential to contribute to Grace’s overall performance, of each executive officer (including our NEOs). In addition, since the number of executive officers is small, the committee is able to spend considerable time with each executive officer outside committee meetings, so the committee members are able to develop strong holistic views of each executive officer’s performance and potential. The committee also reviews each executive officer’s existing compensation. This information, presented in the form of a “tally sheet,” reflects all compensation payable or potentially payable to each executive officer under our compensation program. For each executive officer, the committee reviews the tally sheet, the peer group information, and broad industry data to provide context to the compensation decisions. The committee then reviews the recommendation of the CEO, as discussed below, solely with respect to the other

63    W. R. GRACE & CO.


executive officers, and makes the compensation determination based on its individual evaluation of each executive officer.
The committee’s process for determining the compensation of the CEO is similar to the process it applies to other executive officers. The committee reviews and approves corporate goals and objectives used in determining the compensation of the CEO. The committee evaluates the CEO’s performance considering those goals and objectives as well as market data and has sole authority to determine the CEO’s compensation based on this evaluation. The CEO plays no part in the committee’s deliberations concerning, or approval of, the CEO’s own compensation. The committee believes the CEO’s compensation should be higher than the compensation of other executive officers because the CEO is uniquely positioned to influence all aspects of our operations and performance and the resulting return to our shareholders. In addition, the committee believes that a competitive compensation package that aligns the interests of the CEO with Grace’s shareholders is the most effective way to incentivize the CEO and maximize Company performance. The committee’s view is consistent with the practices of the compensation peer group companies and the broad industry data that the committee has reviewed, as described in greater detail in the section below titled “Role of the Compensation Consultant.”
Effect of Dividends on LTIP Awards
In January of 2016, Grace announced that it would commence paying a regular quarterly cash dividend per share of common stock. The Company paid the first such dividend in June 2016 and increased the dividend in the first quarter of 2017. Following common market practice, the committee approved “dividend equivalent” paymentsaccruals for holders of unvested restricted stock unitsRSUs and PBUs (which would be paid to holders only following unit vesting)vesting of the underlying award). Unvested PBUs and restricted stock units are “stock equivalents” and not actual stock, so holders accrue corresponding dividend equivalents. Dividend equivalents will accrue quarter by quarter,quarterly (based on target levels, in the case of PBUs) throughout the vesting period on all unvested PBUs and restricted stock units. Those who holdRSUs. In the case of PBUs will accrue dividend equivalents at a target level for any outstanding PBUs. We willwe then adjust these dividend equivalents for actual companyCompany performance (financial results) at the end of the performance period to correspond with the number of PBUs earned. In the event an employee leaves the Company before dividend equivalents are paid, for retirement,


disability, or voluntary/involuntary termination, proration rules would apply to the dividend equivalents and any resulting unvested dividends would be forfeited. Consistent with common market practice, we willWe do not provide dividend equivalents for stock option awards.
2018-2020 Long-Term Incentive Compensation Plan (or “2018 LTIP”) — PBUs
PBUs represented approximately 50% of the value of our 2018 LTIP awards. The PBUs are share-denominated and the actual number of shares earned by the NEOs in respect of the 2018 PBUs was determined based on the achievement of specified business performance objectives through December 31, 2020. Specifically, the realized value of an individual payout under a 2018 PBU award was based upon:
the individual’s PBU target share amount;

55    W. R. GRACE & CO.


the growth in our LTIP Adjusted EPS over the three-year performance period;
the TSR for the three-year performance period as compared to the Russell 1000; and
the value of Grace common stock on the payout date.
Payouts to the NEOs in respect of PBUs are made in shares of Grace common stock. The three-year EPS targets are set taking into account anticipated repurchases by the Company of its common stock; the committee has discretion to adjust for share repurchases above or below such anticipated levels.
2018 LTIP Performance Target — LTIP Adjusted EPS
The committee selected Adjusted EPS as the primary performance measure for the 2018 PBUs, reflecting our focus on long-term operational excellence and quality of earnings. The Adjusted EPS targets were reflective of a baseline Adjusted EPS of $3.36. In order to earn 100% of the target share amount, our cumulative annual LTIP Adjusted EPS growth from the 2017 baseline performance to 2020 actual performance had to reach $4.75 (approximately 141% of the $3.36 baseline amount), as reflected in the following table:

2018 LTIP Performance Target — TSR
The committee selected TSR as the second performance measure for 2018 PBU awards, regardlesswhich provided enhanced alignment with actual shareholder value creation. We calculate Total Shareholder Return as the growth in stock price between the first and last business day of whether theythe performance period plus dividends reinvested compared to the same figure for the Russell 1000 Index. The number of PBU shares to be paid out based upon EPS targets as shown in the above table was subject to adjustment, up or down, by a factor of 25% if relative TSR for the three-year period 2018-2020 is above the 75th percentile or below the 25th percentile of the Russell 1000 Index, respectively, subject to a maximum funding percentage of 200. The committee chose the Russell 1000 Index as it is a broad representation of similarly-sized companies, including a majority of the Company’s peers.
2018-2020 LTIP Adjusted EPS and Total Shareholder Return Results and 2018-2020 PBU Payouts
Based on the final EPS results, the formulaic payout of the 2018-2020 PBUs was 0% based on the direct impact of COVID-19 on our 2020 performance. The committee believed that this result did not accurately reflect the achievements of the executive team over the performance period, and with the advice of its independent compensation consultant, explored ways to more effectively balance pay and performance alignment.
The committee determined that it was important to recognize the financial accomplishments that the executive team had achieved through the first two years of the performance period prior to the pandemic, while holding the executive team accountable for the Company’s financial performance in the final year of the period. The committee also determined that it was important to hold the executive team accountable for relative shareholder value creation across the full performance period. The committee concluded that it was appropriate to bifurcate the three-year performance period to reflect the unanticipated impact of COVID-19.

Through bifurcating the performance period, the committee believed the adjusted award enabled appropriate recognition of the above target performance delivered in the first two years of the performance period. The first period included 2018 and 2019, and the second period related to 2020. The target opportunity was pro-rated for the two periods, with the 2018-2019 period having two-thirds of the original opportunity and 2020 having one-third. The relative TSR modifier, measured over the original three-year performance period, continued to have effect for the full award. The Adjusted EPS goal was not modified; rather, payout in respect of the 2018-2019 period was based on progress towards the pro-rated original 2020 goal.
gracegraphics0324211a.jpg
Achievement related to the adjusted award segment pertaining to 2018 and 2019 was assessed based on progress towards achieving the 2020 target goal, pro-rated for the length of the segment performance period.
The target goal of $4.75 for 2020 represented a $1.39 improvement in Adjusted EPS compared to 2017 Adjusted EPS of $3.36 (Adjusted EPS for 2017 of $3.40 was further adjusted downward by $0.04 for stock-based compensation changes driven by Accounting Standards Update 2016-09). In 2019, the Company achieved Adjusted EPS of $4.38, a $1.02 improvement over the 2017 Adjusted EPS baseline. This represented the Company achieving 73% progress towards the 2020 target by the end of 2019 ($1.02 two-year improvement divided by the $1.39 three-year improvement goal).
Awards are vested or unvested.also subject to a relative TSR modifier which adjusts the payout depending on the Company’s stock price performance when compared to the Russell 1000 index. Given this measure is, by design, self-calibrating (given the fact the Company’s TSR peers were also affected by COVID-19 and other environmental impacts in 2020) the committee did not believe it was necessary to adjust for the impact of COVID-19. Our TSR performance for the three-year period relative to the constituents in the Russell 1000 over the same period was in the lowest quartile, resulting in an additional 25% reduction in the number of PBUs earned in accordance with our program design (in other words, the number of earned PBUs was multiplied by 75%).

Other Components and Features of our Executive Compensation Program
Pension Plan/Supplemental Executive Retirement Plan
As described below under the caption "—“—Compensation Tables—Pension Benefits," payments under our tax-qualified pension plan are calculated using annual compensation, including base salary and AICP awards, and years of credited Grace service. The committee has also implemented a Supplemental Executive Retirement Plan, generally referred to as a SERP, which applies to approximately 5550 executive employees, including the executive officers,NEOs whose annual compensation exceeds the amount that can be taken into account for purposes of calculating benefits under tax-qualified pension plans. Under this plan, each such employee will receive the full pension to which that employee would be entitled in the absence of the limitations described above and other limitations imposed under federal income tax law. The SERP is unfunded and is not qualified for tax purposes. The defined benefit pension plan and SERP have been closed to new entrants since January 1, 2017. Furthermore, in January 2021, Grace announced both plans will be frozen as of December 31, 2024 and as of January 1, 2025, all participants will be moved to a defined contribution retirement plan already in place for new hires as of January 1, 2017.
Savings and Investment Plan/Replacement Payment Plan
We generally offer a tax-qualified 401(k)-type Savings and Investment Plan, or S&I Plan, to employees under which they may save a portion of their annual compensation in investment accounts on a pre- or post-tax basis. During 2017,2020, we matched 100% of employee savings under the S&I Plan up to 6% of the employee'semployee’s base salary and annual incentive compensation. The committee believes that a 401(k)-type plan with a meaningful companyCompany match is an effective recruiting and retention tool for our employees, including our executive officers.NEOs. The committee has also implemented

58    W. R. GRACE & CO.


an S&I Plan Replacement Payment Plan that currently applies to approximately 5545 executive employees, including the executive officers,NEOs, whose annual compensation exceeds the amount that can be taken into account for purposes of calculating benefits under tax-qualified savings plans.plans, including the S&I Plan. Under this plan,the Replacement Plan, each such employee will receive the full matching payments to which that employee would be entitled in the absence of the limitations described above and other limitations imposed under federal income tax law.
Executive Personal Benefits
The committee believes that executive personal benefits should be limited. Executive officers, including the NEOs, are eligible to participate in an executive physical examination program that offers executives an annual comprehensive physical examination. Mr. FestaOur CEO has access to corporate aircraft for reasonable personal travel though he isand would be responsible for paying income taxes on the value of such travel as determined by the Internal Revenue Service. In connection with joining Grace, Mr. Blaser received certain benefits in 2017 related to relocation, at Grace's request, to Maryland.
Change in Control Severance Agreements
As described below under the caption "—“—Compensation Tables—Termination and Change in Control Arrangements," we have entered into change in control severance agreements with each of the named executive officers.NEOs. We base the provisions in these agreements on competitive practice and design them to ensure that the executive officers'NEOs’ interests remain aligned with the interests of our stockholdersshareholders if a potential change in control occurs. Payments under these agreements are triggered by the involuntary termination of the executive officer'sofficer’s employment without cause (including constructive termination caused by a material reduction in his or her authority or responsibility or by certain other circumstances) following a change in control.control, commonly referred to as a “double-trigger” arrangement. A change in control situation often undermines an executive officer'sofficer’s job security, and it is to our benefit and our stockholders'shareholders’ benefit to encourage our executive officers (including the NEOs) to seek out beneficial transactions and to remain employed through the closing of any transaction, even though their future employment at Grace may be uncertain. The change in control severance agreements are designed to reinforce and encourage the continued attention and dedication of the executive officersNEOs to their assigned duties without distraction in the face of potentially adverse


circumstances arising from the possibility of a change in control of Grace. Certain terms of these agreements are described below under the caption "—“—Compensation Tables—Potential Payments Upon Termination or Change in Control."
Severance Arrangements
Grace maintains the Severance Plan for Leadership Team Officers of W. R. Grace & Co. (the “Executive Severance Plan”), which provides that, if the employment of an executive officer (including our NEOs) is terminated without cause without a change in control, he or she will be entitled to cash severance equal to the sum of his or her base salary and target bonus (two times the sum, in the case of the CEO). The Executive Severance Plan also provides that, upon a termination without cause not due to a change in control, an executive officer will be entitled to a prorated annual bonus for the year of termination if he or she has completed at least three months of employment in the applicable year. Payments under the Executive Severance Plan are contingent upon the executive officer’s execution and non-revocation of a release of claims and non-compete and non-solicitation of employees covenants, in favor of Grace. The Executive Severance Plan replaced, and each executive officer has waived all rights under, all individual agreements or arrangements that provided for cash severance to an executive officer if the employment of such executive officer is terminated without cause not due to a change in control. We designed our severance arrangements to encourage and reinforce the continued attention and dedication of our executive officers to their assigned duties, without undue concern regarding their job security. The Executive Severance Plan meets these goals and in addition, equalizes the severance arrangements for all of the named executive officers, with the exception noted for the CEO. See below under “—Compensation Tables—Termination and Change in Control Arrangements” and "—Potential Payments Upon Termination or Change in Control.”Control” and under “—Termination and Change in Control Arrangements” in that section.
Executive Salary Protection Plan
As described below under the caption "—“—Compensation Tables—Potential Payments Upon Termination or Change in Control," our Executive Salary Protection Plan (“ESPP”) provides payments to our named executive officers,NEOs, or their respective beneficiaries, in the event of their disability or death prior to age 70 while employed by Grace. We designed the plan to encourage the continued attention and dedication of our executive officers (including our NEOs) to their assigned duties without undue concern regarding their ability to earn a living and support their families in the event of death or disability.

Vesting under the 2018 Stock Incentive Plan
Under the 2018 Stock Incentive Plan, subject to change in control provisions thereof, stock incentives shall vest no earlier than the first anniversary of the date the stock incentive is granted; provided, however, that, stock incentives that result in the issuance of an aggregate of up to 5% of the shares of Common Stock available under the Plan may be granted to any one or more NEOs without respect to such minimum vesting provisions and nothing therein shall preclude the committee from accelerating or maintaining the vesting of any stock incentives in connection with a named executive officer’s death, disability, retirement or other termination of Service.
Executive Compensation Program Philosophy, Objectives, and Processes
Alignment between Pay and Performance
The committee believes that the Company’s executive compensation program provides a strong linkage between pay and performance and is well-aligned with shareholder interests. Our measures of performance under our AICP and LTIP — Adjusted Net Sales, Adjusted EBIT, Adjusted Free Cash Flow, EPS and TSR, are accepted measures of financial success by the investment community, and similar measures are also used by our peer companies in various forms of incentives. The committee sets targets for these measures based on the macroeconomic environment, competitive dynamics, and factors unique to the Company. The committee designs these targets which, if attained, represent excellent performance by the Company. If the Company achieves or exceeds these targets, the committee believes executives generally should be rewarded with higher payouts of awards, and if targets are not met, executives generally should receive lower or no awards.
Key Objectives
The key objectives of the Grace executive compensation program for executive officers are to incentivize and motivate our executive officers to improve our performance, deliver our growth plan, and increase shareholder value; and to enable us to compete effectively with other firms in attracting, motivating and retaining executives. We designed the incentive compensation portion of the program to closely align the financial interests of our executive officers with those of our shareholders. Because executive officers have a substantial ability to influence business success, we believe that the portion of compensation that is at-risk based on organization-wide performance should increase as the level of responsibility increases.
We also expect the executive compensation program to be applied consistently with our culture of ethical conduct, personal integrity, and compliance with both our policies and applicable law. We expect our executive officers to lead by example, modeling our Grace Core Values in their daily business conduct. The Grace Core Values consist of a commitment to teamwork, performance, integrity, speed and innovation, which, with our overall commitment to safety, are the foundation of our corporate culture.
Share Ownership Guidelines
Our Board has designed and implemented share ownership guidelines to align the long-term financial interests of our directors and executive officers with the long-term interests of our shareholders. The guidelines are set forth under “Proposal One—Election of Directors—Corporate Governance—Share Ownership Guidelines” and are incorporated herein by reference.
How We Set Compensation — Elements and Target Mix
Our Board has delegated to the committee, the authority for approving and administering the compensation program for executive officers (including the NEOs in the Summary Compensation Table set forth under “—Compensation Tables”). Our Board has appointed all of the independent members of our Board to serve as members of the committee.

60    W. R. GRACE & CO.


Elements of Compensation
The following table outlines the major elements of compensation in 2020 for the NEOs:

Target Compensation Mix
As determined by the committee, and informed by market practices, our compensation mix at target (shown above for both our CEO and, collectively, for the other NEOs) is largely incentive-based. The charts further below include 2020 base salary, target AICP, and grant date fair values for the 2020 LTIP grants. The charts illustrate how the mix of target total direct compensation for our NEOs emphasizes incentive compensation, with a significant focus on long-term incentives tied to our long-term performance. Further, the charts indicate the high percentage of executive compensation that is “at-risk,” demonstrating the linkage of shareholder interests and executive officer performance goals.

Compensation Benchmarking
In order to gauge market compensation levels and practices, the committee has retained the services of WTW, a leading independent global advisory, broking and solutions company. Periodically, the committee consults with WTW for an assessment of our executive officer compensation program relative to the competitive market.
The committee, with the assistance of WTW, has selected the companies below as our compensation peer group based upon their industry (those being chemicals, materials and specialty chemicals), size and global scope, revenues, profitability, market capitalization, market for talent, and the availability of public information regarding their compensation practices. The committee relies upon the compensation data gathered from the peer group as well as published broad industry survey data, reflecting the chemicals and general industries, to represent the competitive market for executive talent for our executive officers, and does not focus on any specific data or benchmark for guidance when making pay decisions. The committee reviews the composition of our compensation peer group annually to ensure that it remains suitable and appropriate and removes companies that are no longer public entities.
Peer Group
Albemarle Corp.Hexcel Corp.
Ashland Global Holdings Inc.International Flavors & Fragrances Inc.
Cabot Corp.Minerals Technologies Inc.
Celanese CorporationNewMarket Corporation
Element Solutions Inc.PQ Corporation
Ferro CorporationRPM International Inc.
FMC Corp.Sensient Technologies Corporation
HB Fuller Co.Stepan Company
When reviewing the appropriateness of including companies in our peer group based on revenues, we consider the total net sales of Advanced Refining Technologies LLC (or “ART”), our joint venture with Chevron Products Company, a division of Chevron U.S.A. Inc., given our significant managerial responsibilities in connection therewith. Net sales of ART, an unconsolidated affiliate in which we have a 50% interest, were $481.9 million during 2020. We also consider total ART net sales in survey benchmarking.

Contributions of the Committee, CEO and Consultant in our Executive Compensation Process
Role of the Compensation Committee
Pursuant to a delegation from our Board, the committee is responsible for reviewing and approving the compensation of all executive officers, including:
base salary
annual incentive compensation
long-term incentive compensation
employment agreements
severance arrangements
change in control agreements
any special or supplemental benefits not generally available to salaried employees
The committee oversees executive development and succession planning for the CEO and the other executive officers; reviews management’s goal setting process; identifies important year-over-year and multi-year targets; and commits the executive compensation program to a rigorous review annually. The committee reviews and approves all corporate goals and objectives used in determining the incentive compensation of each executive officer including our NEOs. Our human resources department and legal services group provide advice and legal and administrative assistance to aid the committee in meeting its responsibilities.
The committee reviews the distribution of peer group pay practices and broad industry data and determines the appropriate positioning of each executive officer’s compensation based on several factors, including:
the executive officer’s role and level of responsibility
the executive officer’s individual performance in that role
the need to attract, retain and motivate the talent required for world-class leadership
the economic and business environment in which Grace operates
the importance of the executive officer to Grace’s objectives and strategy
internal comparisons of pay and roles within the executive officer group;
legal and governance requirements and standards related to executive compensation, including internal pay equity with other salaried employees
with respect to executive officers other than the CEO, the CEO’s recommendation of appropriate compensation levels
The committee’s compensation philosophy is to attract, retain and motivate employees to deliver results and increase shareholder value, performing in the best interests of the Company and its shareholders. The committee reviews compensation policies and plans to ensure that this philosophy is supported and that such policies and plans allow the Company to compete effectively with other firms in attracting, motivating and retaining the talent required.
Each year, the committee evaluates the leadership ability, business experience, technical skill, and potential to contribute to Grace’s overall performance, of each executive officer (including our NEOs). In addition, since the number of executive officers is small, the committee is able to spend considerable time with each executive officer outside committee meetings, so the committee members are able to develop strong holistic views of each executive officer’s performance and potential. The committee also reviews each executive officer’s existing compensation. This information, presented in the form of a “tally sheet,” reflects all compensation payable or potentially payable to each executive officer under our compensation program. For each executive officer, the committee reviews the tally sheet, the peer group information, and broad industry data to provide context to the compensation decisions. The committee then reviews the recommendation of the CEO, as discussed below, solely with respect to the other

63    W. R. GRACE & CO.


executive officers, and makes the compensation determination based on its individual evaluation of each executive officer.
The committee’s process for determining the compensation of the CEO is similar to the process it applies to other executive officers. The committee reviews and approves corporate goals and objectives used in determining the compensation of the CEO. The committee evaluates the CEO’s performance considering those goals and objectives as well as market data and has sole authority to determine the CEO’s compensation based on this evaluation. The CEO plays no part in the committee’s deliberations concerning, or approval of, the CEO’s own compensation. The committee believes the CEO’s compensation should be higher than the compensation of other executive officers because the CEO is uniquely positioned to influence all aspects of our operations and performance and the resulting return to our shareholders. In addition, the committee believes that a competitive compensation package that aligns the interests of the CEO with Grace’s shareholders is the most effective way to incentivize the CEO and maximize Company performance. The committee’s view is consistent with the practices of the compensation peer group companies and the broad industry data that the committee has reviewed, as described in greater detail in the section below titled “Role of the Compensation Consultant.”
Role of the Chief Executive Officer
The CEO proposes compensation levels for the other executive officers. The CEO bases his recommendations for the other executive officers and NEOs on his personal review of the factors considered by the committee, as described above. The committee affords the CEO’s recommendations significant weight but retains full discretion when determining executive officer compensation. Although not a member of the committee, the CEO attends committee meetings and participates in committee deliberations regarding compensation levels for the other executive officers. The CEO is excused from deliberations regarding his own compensation and from the “executive session” portion of each meeting when the committee meets alone or alone with its outside advisors.
Role of the Compensation Consultant
In order to add rigor in the process of setting executive officer compensation and to inform the committee of market trends, the committee has engaged the services of WTW to analyze our executive compensation structure and plan designs, and to assess whether our compensation program is competitive and supports the committee’s goal to align the interests of our executive team with the interests of our shareholders.
Specific services provided by WTW in 2020 included:
participation in committee meetings
review of our pay-for-performance alignment
review of risk factors associated with the design and administration of our executive compensation program
review of companies included in our compensation peer group
preparation of market compensation data for executives and outside directors
pandemic-specific studies and advice, including comparative information
review of the CEO’s compensation as well as compensation recommendations for the other NEOs
presentation of recommendations for the CEO’s compensation to the committee
assessment of the share usage under our long-term incentive plan versus our peer group
advice on incentive compensation plan design
advice on current market trends and practices
review of compensation disclosure
We expect WTW and our executive officers, including our CEO and our CHRO, to meet, exchange information, and otherwise cooperate in the performance of their respective duties outside committee meetings.
During 2020, the Company paid fees to WTW for services rendered in respect of executive officer and director compensation in the amount of $266,000. In addition, management engaged WTW to provide additional services to

64    W. R. GRACE & CO.


the Company in an amount equal to $134,400 during 2020. These services included human capital and broking, and data, surveys and technology.
The committee has the sole authority to approve the independent compensation consultant’s fees and terms of engagement. The committee annually reviews its relationship with WTW to ensure independence. The process includes a review of the services WTW provides, the quality of those services, and fees associated with the services during 2020 as well as consideration of the factors impacting independence that the NYSE rules require. In its review, the committee noted no conflicts of interest related to the work of WTW and has determined the consultant to be independent.
Compensation Policies and Practices Relating to Risk Management
We do not believe that risks arising from our compensation policies and practices for our employees are reasonably likely to have a material adverse effect on Grace through excessive risk-taking incentives or otherwise. Our compensation program, though tailored to our specific needs, is generally similar to compensation programs used by other companies in our industry. We have many years of experience with the various components of our compensation program, including our incentive plans under which payments may vary based on the performance of the business. We believe these plans, backed by our corporate ethics program and the Grace Core Values, have been successful in aligning the interests of our executives and senior employees with the interests of our stockholdersshareholders and in encouraging the responsible pursuit of corporate objectives by our employees.
In order to ensure that our executive officer compensation program does not encourage excessive risk-taking, the committee conducts a periodic risk assessment of our compensation plans, including their design, structure and administration. In 2017,2020, the committee reviewed risk factors associated with the design and administration of the Company'sCompany’s executive compensation program with Willis Towers Watson.WTW. The committee believes that several elements of our compensation programs mitigate risk, including the use of performance measures based on reasonable targets, the balance of the compensation elements, between time-based and performance-based compensation, the implementation of stockshare ownership guidelines, and hedging/pledging prohibitions, the use of severance and change in control agreements to maintain our executives’ focus in times of uncertainty, and the committee'scommittee’s oversight and discretion regarding incentive compensation.

In addition, as discussed above, to reinforce the alignment of management’s interests with those of our shareholders, and support good governance practices, the Board has adopted an Executive Compensation Recovery Policy (“Clawback”) that applies to all of our NEOs. For additional information, see “Clawback Policy” above.

Deductibility of Executive Compensation
Section 162(m) of the TaxInternal Revenue Code of 1986, as amended, limits the tax deduction for compensation expense each year in excess of $1 million paid to certain executive officers unless suchofficers. As in effect prior to the 2018 tax year, there was an exception from Section 162(m) for “performance-based” compensation is “performance-based” andthat satisfies certain other conditions. Effective with the 2018 tax year, the Tax Cuts and Jobs Act of 2017 eliminated the exception under Section 162(m) for performance-based compensation, unless there was a binding written arrangement with respect to such compensation in place on November 2, 2017. According to the IRS, whether a written arrangement is binding for such purpose will be determined under applicable state law. While the design of the AICP and LTIP was structured to provide flexibility in determining whether compensation payable thereunder may be tax deductible, deductibility iswas only one criterion we considerconsidered when establishing compensationsuch plans. We structured the Grace AICPs and LTIPs with the intention that the compensation payable thereunder will generally qualify as deductible “performance-based” compensation. However, the rules governing Section 162(m) of the Code are complex and subject to different interpretations. Therefore, there is no certainty that awards intended to constitute “performance-based compensation” will, in fact, meet that exception. In addition, we believe that it is important to preserve the ability to structure compensation plans to meet a variety of corporate objectives even if the compensation is not deductible. Tax reform legislation will eliminate the exception for performance-based compensation under Section 162(m) effective for our 2018 tax year.

The Pension Plan and SERP provide for a reduction in pension benefits to individuals who elect early retirement ranging from a 17% reduction for retirement at age 55 to no reduction for retirement at age 62. Although these amounts appear as a lump sum, they are generally paid as an annuity. The amounts reported are accounting values and were not realized by the individuals in cash during 2017. The amounts include benefits that the individuals may not currently be entitled to receive because the individuals are not vested in such benefits.
Retirement Plan for Salaried Employees
Full-timeCertain full-time salaried employees who are 21 or older and who have one or more years of service (including each of the NEOs) are eligible to participate in our Retirement Plan for Salaried Employees, also called the Pension Plan. Under this basicqualified retirement plan, pension benefits are based upon (a) the employee’s average annual compensation for the 60 consecutive months in which his or her compensation is highest during the last 180 months of continuous participation, and (b) the number of years of the employee’s credited Grace service. At age 62, a participant is entitled to full benefits under the Pension Plan, but a participant may elect reduced payments upon early retirement beginning at age 55. For purposes of the Pension Plan, compensation generally includes base salary and AICP awards; however, for 2017,2020, federal income tax law limits to $270,000$285,000 the annual compensation on which benefits under the Pension Plan may be based. As of December 31, 2017, Mr. Festa, Mr. Blaser2020, Messrs. La Force and Mr. Shelnitz areDockman, and Ms. Brown were eligible for early retirement under the Pension Plan, and Messrs. Cole and Shelnitz were eligible for regular retirement under the Pension Plan. The Pension Plan is further described in Item 8 (Financial Statements and Supplementary Data) in the Financial Supplement under Note 8 (Pension Plans and Other Postretirement BenefitsRetirement Plans) to the Consolidated Financial Statements and in Item 7 (Management's(Management’s Discussion and Analysis of Financial Condition and Results of Operations under the caption "Financialcaptions “Financial Condition, Liquidity, and Capital Resources—EmployeeResources” and “Employee Benefit Plans—Defined Benefit Pension Plans"Plans”) in the Financial Supplement of the Company's Annual Report onCompany’s 2020 Form 10-K forOriginal Filing. This benefit plan was closed to new entrants effective January 1, 2017. In January 2021, Grace announced the year endedPension Plan will be frozen as of December 31, 2024 and effective January 1, 2025 all participants will be moved to a defined contribution plan already in place for new hires as of January 1, 2017.
Supplemental Executive Retirement Plan
We also have an unfunded, nonqualified SERP, under which an employee will receive the full pension to which he or she would be entitled in the absence of the limitations described above and other limitations imposed under federal income tax law. With respect to payments, the SERP generally operates in the same manner as the Pension Plan. As of December 31, 2017, Mr. Festa, Mr. Blaser2020, Messrs.

Non-Qualified Deferred Compensation Plan
The following table summarizes the compensation deferred by the named executive officerNEO pursuant to the provisions of Grace’s incentive compensation plan as in effect in 1998, under which certain employees were permitted to voluntarily defer receipt of shares of Grace common stock. Deferred shares under the plan are fully vested and may be distributed to the plan beneficiary upon retirement or termination of service with us. Since 1998, executives may no longer defer receipt of shares under the plan, although existing balances remain in place. In 2020, Mr. Shelnitz was the only NEO who participated in this deferred compensation plan.

Termination and Change in Control Arrangements
Change in Control Severance Agreements
We have entered into change in control severance agreements with all of our executive officers (including the NEOs), which renew automatically unless the Grace Board of Directors elects not to renew them. These agreements generally provide that in the event of the involuntary termination of the individual’s employment without cause (including constructive termination caused by a material reduction in his or her authority or responsibility or by certain other circumstances) following a “change in control,” he or she will generally receive a severance payment equal to three times the sum of his or her annual base salary plus target annual incentive compensation, subject to reduction, pro rata incompensation. In addition, the case of an executive officer who is within 36 months of normal retirement age (65) or, under certain circumstances, to minimizewould also receive a prorated target annual incentive bonus for the effect of certain excise taxes if applicable. year in which the change in control occurs and continued Company-provided health insurance.For purposes of the severance agreements, “change in control” means the acquisition of 20% or more of the outstanding Grace common stock (but not if such acquisition is the result of the sale of common stock by Grace that has been approved by Grace’s Board of Directors)Board), the failure of Board-nominated directors to constitute a majority of any class of Grace’s Board, of Directors, the occurrence of a transaction in which the stockholdersshareholders of Grace immediately preceding such transaction do not own more than 50% of the combined voting power of the entity resulting from such transaction, or the liquidation or dissolution of Grace. The severance amount would be paid in a single lump-sum after termination. Our change in control severance agreements do not provide for any “gross up” or other payments in respect of taxes owed by our executive officers following a termination of employment. The description of the severance agreements in this Proxy Statement does not purport to be complete and is qualified in its entirety by reference to the form of such agreement, which has been filed with the SEC. Further, the change in control severance agreements may be amended in connection with the Merger Agreement.
Severance Arrangements (Without a Change in Control)
Grace maintains the Executive Severance Plan, for Leadership Team Officers of W. R. Grace & Co. (the “Executive Severance Plan”), which provides that, if the employment of an executive officer is terminated without cause withoutthat is not because of a change in control, he or she will be entitled to cash severance equal to one times (two times, in the case of the CEO) the sum of his or her base salary and target bonus. The Executive Severance Plan also provides that, upon a termination without cause not due to a change in control, an executive officer will be entitled to a prorated target annual bonus for the year of termination if he or she has completed at least three months of employment in the applicable year. Payments under the Executive Severance Plan are contingent upon the executive officer’s execution and non-revocation of a release of claims and non-compete and non-solicitation of employees covenants with a duration of 24 months, in favor of Grace. The Executive Severance Plan replaced, and each executive officer has waived all rights under, all individual agreements or arrangements that provided for cash severance to an executive officer if the employment of such executive officer were terminated without cause not due to a change in control.


Our severance arrangements are designed to encourage and reinforce the continued attention and dedication of our executive officers to their assigned duties without undue concern regarding their job security. The Executive Severance Plan meets these goals and, in addition, equalizes the non-change in control severance arrangements for all of the named executive officers,NEOs, with the exceptions noted for the CEO. The description of the severance arrangements in this Proxy Statement does not purport to be complete and is qualified in its entirety by reference to the complete text of the

76    W. R. GRACE & CO.


Executive Severance Plan, which the Company filed with the SEC.
Executive Salary Protection Plan
All executive officers (including the NEOs) participate in the Executive Salary Protection Plan which provides that, in the event of a participant’s disability or death prior to age 70, we will continue to pay all or a portion of base salary to the participant or a beneficiary for a period based on the participant’s age at the time of disability or death. Payments under the plan may not exceed 100% of base salary for the first year and 60% thereafter in the case of disability (50% in the case of death). Any payment under the plan as a result of disability would be reduced by the amount of disability income received under Grace’s long-term and short-term disability plans that are generally applicable to U.S. salaried employees. The payments would be paid in installments in the form of salary continuation. The description of the plan in this Proxy Statement does not purport to be complete and is qualified in its entirety by reference to the complete text of the Executive Salary Protection Plan, which the Company filed with the SEC.
Annual Incentive Compensation Plan
An employee who voluntarily terminates his or her employment prior to an AICP payout date will generally not receive an AICP payment. Under the Executive Severance Plan, an executive officer who completes at least three months of employment in the calendar year in which he or she qualifies for severance under the Executive Severance Plan, would receive a pro rata amount of any bonus the executive officer is eligible to receive for that year under the AICP. This pro rata amount would reflect the executive officer'sofficer’s completed months of service in that year. The amount of any such bonus would depend on the extent that the applicable business performance goals are met (and will be subject to any applicable committee approvals); and also on the executive officer'sofficer’s individual performance while still employed by Grace, provided that the individual performance criteria won’t be used to reduce, or increase, the amount of the executive'sexecutive’s bonus entitlement by more than 25%, based on the determination of the executive'sexecutive’s former management at Grace. Any pro rata bonus to which he or she becomes entitled would be paid at the same time as bonuses are paid to actively employed eligible employees (normally in March after the calendar year to which the bonus relates).
Long TermEffect of Employee Termination—2014 Stock Incentive Plan (2014and 2018 Stock Incentive PlanPerformance-Based Unit (PBU)
Our 2018 Stock Incentive Plan was approved by our Shareholders at our 2018 Annual Meeting of Shareholders. One key difference between our 2014 and Restricted2018 plans is that under the 2018 Stock Unit (RSU) Awards)Incentive Plan, payments are triggered by the involuntary termination of the executive officer’s employment without cause (including constructive termination caused by a material reduction in his or her authority or responsibility or by certain other circumstances) within two years following a change in control, commonly referred to as a “double-trigger” arrangement.
PBU and RSU Awards
An employee whose employment terminates prior to the payout date will forfeit any unpaid PBU or RSU award payment if employment terminates for any of the following reasons:
voluntary termination without the consent of the Compensation Committee;
retirement under a Grace retirement plan prior to age 62 without the consent of the Compensation Committee (except that for awards made after January 1, 2016, for those who leave Grace due to early retirement, with early retirement being defined as retirement with a minimum age of 55 and combined age and years of service of at least 60, PBU and RSU awards will vest on a pro-rata basis, based on the number of completed months of service from the grant date through the retirement date); or
termination for cause.

Under the 2014 Stock Incentive Plan, “change in control” means that a person beneficially owns 20% or more of the outstanding Grace common stock (but not if such ownership is the result of the sale of Grace common stock by Grace that has been approved by Grace’s Board of Directors or pursuant to a plan of reorganization that is confirmed and effective), the failure of Board-nominated directors to constitute a majority of any class of the Grace Board, of Directors, the occurrence of a corporate transaction in which the stockholdersshareholders of Grace immediately preceding such transaction do not own more than 50% of the combined voting power of the entity resulting from such transaction, or the liquidation or dissolution of Grace).Grace. In accordance with the terms of the 2014 Plan, all restrictions and deferral limitations applicable to PBUs and RSUs lapse, and the PBUs and RSUs become free of all restrictions and become fully vested and transferable to the full extent of the original grant.
Under the 2018 Stock Incentive Plan: (a) “change in control” has a similar meaning compared to the 2014 Stock Incentive Plan definition, except that: (i) “a majority of the” Grace Board replaces “a majority of any class of the” Grace Board; and (ii) the definition of Board-nominated directors is expanded to include certain new members; and (b) the Compensation Committee has full and final authority to determine whether a change in control event has occurred.
The 2018 Stock Incentive Plan differs from the 2014 Stock Incentive Plan with respect to treatment of awards upon a change in control.
In accordance with the terms of the 2014 Plan, upon a change in control, stock options immediately become fully vested and exercisable and stock awards become fully vested.
In accordance with the terms of the 2018 Plan —
(a)Stock Incentives Not Assumed. If a change in control occurs and an employee’s PBUs or RSUs are not continued, converted, assumed, or replaced with a substantially similar award by (i) the Company, or (ii) a successor entity (an “Assumption”), and provided that the employee has not had a termination of service, then immediately prior to the change in control such stock incentives shall become fully vested, exercisable and/or payable, as applicable, and all forfeiture, repurchase and other restrictions on such stock incentives shall lapse, in which case, such stock incentives shall be canceled upon the consummation of the change in control in exchange for the right to receive the change in control consideration payable to other holders of Common Stock (subject to certain additional provisions if Section 409A of the Code is applicable).
(b)Stock Incentives Assumed. If a change in control occurs and an employee’s PBUs or RSUs are subject to Assumption, and, within twenty-four (24) months following such change in control (i) such employee’s employment or service with the Company or a successor is terminated other than for cause or (ii) such employee voluntarily terminates his or her employment or service with the Company or a successor entity with good reason, then such employee’s remaining unvested PBUs and RSUs (including any substituted stock incentives) shall become fully vested, exercisable and/or payable, as applicable, and all forfeiture, repurchase and other restrictions on such stock incentives (including any substituted stock incentives) shall lapse, on the date of termination.
In the discretion of the Compensation Committee, an employee whose employment terminates for a reason that is not described above (i.e. involuntary termination not for cause or transfer to the buyer of a Grace business unit) prior to the payout date may receive a PBU or RSU award payment. IfFor an employee whose employment terminates prior to the end of a PBU or RSU performance period receives a PBU or RSU award payment for that performance period,payout date, the amount of the PBU or RSU award payment will generally be prorated for the period of the employee’s service during the performance period and paid at the time the award is paid to active Grace employees.

Question 13:Who will count the votes?
Our transfer agent, EQ Shareowner Services, has been appointed as inspectors of election. Its representative will attend the Annual Meeting and will count the votes.
Question 14:What is the difference between holding shares as a stockholder of record versus as a beneficial owner?
Question 14: What is the difference between holding shares as a shareholder of record versus as a beneficial owner?
Many of our stockholdersshareholders hold their shares as beneficial owner through a broker, bank, financial institution or other nominee or intermediary that serves as stockholdershareholder of record, rather than directly in their own name as stockholdershareholder of record. As summarized below, there are some differences between shares held directly as stockholdershareholder of record and those owned beneficially through a nominee or intermediary that serves as stockholdershareholder of record:
StockholdersShareholders of Record
If your shares are registered directly in your name with our transfer agent, EQ Shareowner Services, you are considered the stockholdershareholder of record with respect to those shares, and the Notice of Annual Meeting and proxy materials are being provided or sent directly to you. As the stockholdershareholder of record, you have the right to grant your voting proxy directly to us, or to vote in person at the Annual Meeting. If you have requested printed proxy materials, we have enclosed a proxy card for you to use.


Beneficial Owners
If your shares are held in a stock brokerage account or by a bank, financial institution or other nominee or intermediary, you are considered the beneficial owner of shares held in “street name,” and the Notice of Annual Meeting and these proxy materials are being forwarded to you by your nominee or intermediary who is considered the stockholdershareholder of record with respect to those shares. As the beneficial owner, you have the right to direct your

83    W. R. GRACE & CO.


nominee or intermediary on how to vote and are also welcome to attend the Annual Meeting. However, since you are not the stockholdershareholder of record, you may not vote these shares in person at the Annual Meeting unless you request, complete and deliver a legal proxy from your nominee or intermediary. If you requested printed proxy materials, your nominee or intermediary should have enclosed a voting instruction card for you to use in directing the nominee or intermediary regarding how to vote your shares. If a voting instruction card was not included in the printed proxy materials, please contact your nominee or intermediary to determine how to provide voting instructions.
Question 15:Why is it important for me to vote?
If you do not vote, your shares may not be represented at the Annual Meeting. This may result in matters not receiving the number of votes necessary for their approval.
Question 16:What is the effect of not voting?
Shares you own in “street name” through a broker, bank, financial institution or other nominee or intermediary and you do not vote:
In the absence of your voting instructions, your broker, bank, financial institution or other nominee or intermediary may or may not vote your shares at its discretion depending on the proposals before the Annual Meeting. We understand that your nominee or intermediary may vote your shares at its discretion on “routine matters” and that your nominee or intermediary may not vote your shares on proposals that are not “routine.” When your broker submits a proxy for your shares but does not indicate a vote for a particular proposal because of the absence of voting instructions, a “broker non-vote” occurs. Broker non-voted shares count toward the quorum requirement, but are not counted as voted for or against a proposal, or as abstentions, nor are they counted to determine the number of votes present for a particular proposal.
We believe that Proposal Two (Ratification of PricewaterhouseCoopers LLP as our independent registered public accountants) is a routine matter on which nominees or intermediaries can vote on behalf of their clients if clients do not furnish voting instructions. Proposals One, Three and Four are non-routine matters so your nominee or intermediary is not entitled to vote your shares on these proposals without your instructions.
Shares you own that are directly registered in your name and you return a proxy card without giving specific voting instructions:
If you are a stockholdershareholder of record and you sign and return a proxy card without giving specific voting instructions, your shares will count toward the quorum requirement and the proxy holders will vote your shares in the manner recommended by our Board of Directors on all matters presented in this Proxy Statement and the proxy holders may vote in their discretion for any other matters properly presented for a vote at the Annual Meeting.
Shares you own that are directly registered in your name and you do not return a proxy card and you do not vote:
In this case, your unvoted shares will not be represented at the Annual Meeting and will not count toward the quorum requirement. If a quorum is obtained, your unvoted shares will not impact Proposal One or whether stockholdersshareholders approve or reject Proposals Two, Three orand Four.

Question 17: What vote is required to approve each proposal, assuming a quorum is present at the Annual Meeting?

Question 17:What vote is required to approve each proposal, assuming a quorum is present at the Annual Meeting?
The required vote to approve each proposal will depend on the proposal.
Proposal One:In January 2015, we adopted a majority voting standard for the election of directors. Under this voting standard, once a quorum has been established with respect to an election that is not contested, directors are elected by a majority of the votes cast. This means that the number of shares voted FOR a director nominee must exceed the number of shares voted AGAINST that director nominee. Abstentions and broker non-votes are not counted as a vote cast either FOR or AGAINST a director nominee. Under our Amended and Restated Certificate of Incorporation, our By-laws and the Delaware General Corporation Law, a director holds office until a successor is elected and qualified or until his or her earlier resignation or removal. If a director standing for re-election is not elected by the requisite majority of the votes cast in an

84    W. R. GRACE & CO.


uncontested election, that director must tender his or her resignation following certification of the stockholdershareholder vote. The Nominating and Governance Committee of our Board of Directors will make a recommendation to our Board of Directors on whether to accept or reject the resignation, or whether other action should be taken. Our Board of Directors will consider and act on the committee’s recommendation and publicly disclose its decision and the rationale behind it within 90 days from the date of the certification of the election results. Any director who offers his or her resignation will not participate in the committee’s or our Board of Directors’Board’s decision. In a contested election, where the number of nominees exceeds the number of directors to be elected as provided in our By-laws, directors will be elected by a plurality of the votes cast. The election of directors at the Annual Meeting is uncontested and, therefore, the majority voting standard will apply.
Proposal Two:The affirmative vote of a majority of the shares present, in person or by proxy, and entitled to vote is required to approve the ratification of the appointment of PricewaterhouseCoopers LLP as Grace'sGrace’s independent registered public accounting firm for fiscal year 2018.2021. This means that abstentions will have the same effect as votes against the proposal. We do not expect broker non-votes (described above) on Proposal Two since we believe this is a "routine"“routine” matter.
Proposal Three:The affirmative vote of a majority of the shares present, in person or by proxy, and entitled to vote is required to approve the advisory vote on the compensation of our named executive officers. This means that abstentions will have the same effect as votes against the proposal. Broker non-votes will have no effect on the outcome of the vote. Because your vote is advisory, it will not be binding on our Board or Grace. However,Grace; however, our Board will review the voting results and take them into consideration when making future decisions regarding executive compensation.
Proposal Four: The frequency of the advisory vote on the compensation of our named executive officers that receives the affirmative vote of a majority of the shares present, in person or by proxy, and entitled to vote is required to approve- every one year, every two years or every three years - will be the W. R. Grace & Co. 2018 Stock Incentive Plan. This meansfrequency that abstentions will have the same effect as votes against the proposal. Broker non-votes will have no effect on the outcomeshareholders approve. If none of the vote.frequencies receives a majority of the votes, then the frequency that receives the greatest number of votes will be deemed to be the frequency that the shareholders approve. Because your vote is advisory, it will not be binding on our Board or Grace; however, our Board will review the voting results and take them into consideration when making future related decisions.
Question 18:What shares are covered by my proxy card or voting instruction card?
The shares covered by your proxy card represent the shares of Grace common stock that are registered directly in your name with our transfer agent, EQ Shareowner Services. If your shares are held in a brokerage account or by a bank, financial institution or other nominee or intermediary, you will not receive a proxy card; you are considered the beneficial owner of shares and your nominee or intermediary should have enclosed a voting instruction card for you to use in directing how to vote your shares.


Question 19:What does it mean if I get more than one set of proxy materials?
It means your shares are held in more than one account. You should vote the shares represented by the proxy materials using one of the four ways to vote. To provide better stockholdershareholder services, we encourage you to register all of your shares that are held directly in the same name and address. You may do this by contacting our transfer agent, EQ Shareowner Services, toll-free at 1-800-648-8392 or 1-651-450-4064 (Outside the U.S.).
Question 20:Who can attend the Annual Meeting?
All stockholdersshareholders of record and their duly appointed proxies and all beneficial owners of shares held through a broker, bank, financial institution or other nominee or intermediary that serves as stockholdershareholder of record, as of the close of business on March 13, 2018,May 19, 2021, may attend the Annual Meeting.

ANNEX
Annex A

Important Information Concerning GAAP and Non-GAAP Financial MeasuresMeasures; Certain Definitions; and our Forward-looking Statements Notice
In this Proxy Statement, we present financial information in accordance with U.S. GAAP, as well as non-GAAP financial information. StockholdersSee the information below in this Annex. Shareholders are also directed to Part II, Item 8 on page 26pages 58 through 115, inclusive, of our Annual Report on2020 Form 10-K for the fiscal year ended December 31, 2017, our "2017 Form 10-K", and the information incorporated therein from the Financial Supplement of our 2017 Form 10-K,Original Filing for financial information presented in accordance with U.S. GAAP. For information on non-GAAP financial measures, stockholdersshareholders should refer to the "Resultsinformation below and the “Results of Operations"Operations” section of Management'sManagement’s Discussion and Analysis of Financial Condition and Results of Operations in that Financial Supplementour 2020 Form 10-K Original Filing on pages F-6031 through F-73.47, inclusive.
We believe that the non-GAAP financial information provides useful supplemental information about the performance of our businesses, improves period-to-period comparability, and provides clarity on the information our management uses to evaluate performance and determine compensation. In our 20172020 Form 10-K Original Filing, and below, we have provided reconciliations of these non-GAAP financial measures to the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP. The non-GAAP financial measures should not be considered as a substitute for financial measures calculated in accordance with U.S. GAAP, and the financial results calculated in accordance with U.S. GAAP and reconciliations from those results should be evaluated carefully.
How we define, calculate and use certain non-GAAP financial measures
We define Adjusted EBIT (a non-GAAP financial measure) to be net income from continuing operations attributable to W. R. Grace & Co. shareholders adjusted for interest income and expense; income taxes; costs related to legacy product, environmental and other claims;matters; restructuring and repositioning expenses and asset impairments; pension costs other than service and interest costs, expected returns on plan assets, and amortization of prior service costs/credits; income and expense items related to divested businesses, product lines, and certain other investments; gains and losses on sales and exits of businesses, product lines, and certain other investments; third-party acquisition-related costs and the amortization of acquired inventory fair value adjustment; gains and losses on modification or extinguishment of debt; the effects of these items on equity in earnings of unconsolidated affiliate; and certain other items that are not representative of underlying trends.
We define Adjusted Free Cash Flow (a non-GAAP financial measure) to be net cash provided by or used for operating activities from continuing operations minus capital expenditures plus cash flows related to legacy product, environmental and other claims;matters; cash paid for restructuring and repositioning; capital expenditures related to repositioning; cash paid for third-party acquisition-related costs; andcash flows related to debt modification; accelerated payments under defined benefit pension arrangements.arrangements; and certain other items that are not representative of underlying trends.

91    W. R. GRACE & CO.


We define Adjusted Net Sales (a non-GAAP financial measure) as net sales adjusted for the difference between actual foreign currency exchange rates and our annual operating plan exchange rates.
We define Adjusted Earnings Per Share (EPS) (a non-GAAP financial measure) to be diluted EPS from continuing operations adjusted for costs related to legacy product, environmental and other claims;matters; restructuring and repositioning expenses and asset impairments; pension costs other than service and interest costs, expected returns on plan assets, and amortization of prior service costs/credits; income and expense items related to divested businesses, product lines, and certain other investments; gains and losses on sales and exits of businesses, product lines and certain other investments; third-party acquisition-related costs and the amortization of acquired inventory fair value adjustment; certain discrete tax items;gains and losses on modification or extinguishment of debt; certain other items that are not representative of underlying trends.trends; certain discrete tax items; and income tax expense related to historical tax attributes.
“Legacy matters” include legacy (i) product, (ii) environmental, and (iii) other liabilities, relating to past activities of Grace.
In the 2020 first quarter, the definition of Adjusted EBIT was modified to adjust for the effects of interest and taxes on equity in earnings of unconsolidated affiliate. We made these changes to provide clarity about the impacts of these items on our equity in earnings of unconsolidated affiliate and to improve consistency in our application of non-GAAP financial measures. Previously reported amounts were revised to conform to the current presentation.
We use Adjusted EBIT, Adjusted Free Cash Flow, Adjusted Net Sales, and Adjusted EPS as performance measures in determining certain incentive compensation.
Adjusted EBIT, Adjusted Free Cash Flow, Adjusted Net Sales, and Adjusted EPS are non-GAAP financial measures; do not purport to


represent income measures as defined under U.S. GAAP,GAAP; and should not be used as alternatives to such measures as an indicator of our performance. We provide these measures to investors and others to improve the period-to-period comparability and peer-to-peer comparability of our financial results, and to ensure that investors and others understand the information we use to evaluate the performance of our businesses. They distinguish the operating results of our current business base from the costs of our legacy product, environmental and other claims;matters; restructuring and repositioning activities; divested businesses; and certain other items. These measures may have material limitations due to the exclusion or inclusion of amounts that are included or excluded, respectively, in the most directly comparable measures calculated and presented in accordance with U.S. GAAP, and thus investors and others should review carefully theour financial results calculated in accordance with U.S. GAAP.

Adjusted EBIT has material limitations as an operating performance measure because it excludes costs related to legacy product, environmental and other claims,matters, and may exclude income and expenses from restructuring, repositioning, and repositioningother activities, and divested businesses, which historically have been material components of our net income. Adjusted EBIT should be evaluated together with net income and net income attributable to Grace shareholders, measured under U.S. GAAP, for a complete understanding of our results of operations.

See below for financial measure reconciliations.



Numbers are subject to rounding. Notably, how we define, calculate and use non-GAAP financial measures can naturally change over time based upon changes in facts and circumstances as businesses and practices evolve.

ANNEX B


95    W. R. GRACE & CO.
2018 STOCK INCENTIVE PLAN


1.
    Purposes. The purposes of the Plan are: (a) to enable the Company to provide Key Persons with long-term incentive compensation that closely aligns the interests of our Key Persons with those of our stockholders; and (b) to enable the Company to compete effectively with other organizations offering similar or other incentives, in attracting, motivating and retaining Key Persons.

2.    Definitions. When used in this Plan, the following terms shall have the meanings set forth in this Section 2.

Board of Directors: The Board of Directors of the Company.

Cessation of service (or words of similar import): When a person ceases to be an employee of the Company or a Subsidiary, or ceases to serve as a Director, as appropriate. For purposes of this definition, if an entity that was a Subsidiary ceases to be a Subsidiary, persons who immediately thereafter remain employees of that entity (and are not employees of the Company or an entity that is a Subsidiary) shall be deemed to have ceased service.

Change in Control: Shall be deemed to have occurred if (a) the Company determines that any "person" (as such term is used in Sections 13(d) and 14(d) of the Exchange Act), other than a trustee or other fiduciary holding securities under an employee benefit plan of the Company or a corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company, has become the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of twenty (20%) percent or more of the outstanding Common Stock of the Company (provided, however, that a Change in Control shall not be deemed to have occurred if such person has become the beneficial owner of twenty (20%) percent or more of the outstanding Common Stock as the result of a sale of Common Stock by the Company that has been approved by the Board of Directors); (b) individuals who are "Continuing Directors" (as defined below) cease to constitute a majority of the Board of Directors; (c) there occurs a reorganization, merger, consolidation or other corporate transaction involving the Company (a "Corporate Transaction"), in each case, with respect to which the stockholders of the Company immediately prior to such Corporate Transaction do not, immediately after the Corporate Transaction, own fifty (50%) percent or more of the combined voting power of the corporation resulting from such Corporate Transaction; or (d) the stockholders of the Company approve a complete liquidation or dissolution of the Company. “Continuing Director” for purposes of the above means (i) any member of the Board of Directors who was such a member on the date on which this Plan was approved by the Committee and any successor to such a Continuing Director who is approved as a nominee or elected to succeed a Continuing Director by a majority of Continuing Directors who are then members of the Board of Directors and (ii) any new member who is nominated or elected to become a director of the Board of Directors by a majority of Continuing Directors who are then members of the Board of Directors. Notwithstanding the foregoing, if a Change in


Control constitutes a payment event with respect to any Stock Incentive (or any portion of an Stock Incentive) that provides for the deferral of compensation that is subject to Section 409A, to the extent required to avoid the imposition of additional taxes under Section 409A, the transaction or event described in subsection (a), (b), (c) or (d) with respect to such Stock Incentive (or portion thereof) shall only constitute a Change in Control for purposes of the payment timing of such Stock Incentive if such transaction also constitutes a “change in control event,” as defined in Treasury Regulation Section 1.409A-3(i)(5).
The Committee shall have full and final authority, which shall be exercised in its sole discretion, to determine conclusively whether a Change in Control has occurred pursuant to the above definition, the date of the occurrence of such Change in Control and any incidental matters relating thereto; provided that any exercise of authority in conjunction with a determination of whether a Change in Control is a “change in control event” as defined in Treasury Regulation Section 1.409A-3(i)(5) shall be consistent with such regulation.
Code: The Internal Revenue Code of 1986, as amended, and the rules and regulations issued thereunder.
Committee: The Compensation Committee of the Board of Directors of the Company or any other committee or entity designated by the Board of Directors to administer stock incentive and stock option plans of the Company and the Subsidiaries generally or this Plan specifically. However, the grant of Stock Incentives to individuals who are subject to Section 16 of the Exchange Act may only be made by a Committee which consists of not less than two (2) members of the Board of Directors of the Company, each of whom is a "non-employee director" within the meaning of Rule 16b-3 under the Exchange Act.
CommonStock: The common stock of the Company, par value $.01 per share, or such other class of shares or other securities or property as may be applicable pursuant to the provisions of Section 9.
Company: W. R. Grace & Co., a Delaware corporation.
Continuing Director: The meaning set forth in the definition of “Change in Control” above.
Corporate Transaction: The meaning set forth in the definition of "Change in Control" above.
Director: A member of the Board of Directors of the Company who is not an employee of the Company.
Effective Date: The date that the Plan becomes effective in accordance with Section 11.
Exchange Act: The Securities Exchange Act of 1934, as amended.

3. Grants ofStock Incentives. (a)Subject to the provisions of this Plan, the Committee may at any time and from time to time, grant Stock Incentives under this Plan to, and only to, Key Persons.


(b)    The Committee may grant a Stock Incentive to be effective at a specified future date or upon the future occurrence of a specified event. For the purposes of this Plan, any such Stock Incentive shall be deemed granted on the date it becomes effective. An agreement or other commitment to grant a Stock Incentive that is to be effective in the future shall not be deemed the grant of a Stock Incentive until the date on which such Stock Incentive becomes effective.
(c)A Stock Incentive may be granted in the form of:
(i)a Stock Award, or
(i)an Option or SAR, or
(ii)a Net Exercise Option, or
(iii)a combination of a Stock Award, an Option, SAR and/or Net Exercise Option.
(d)Vesting. Notwithstanding any other provision of the Plan to the contrary, but subject to Section 15 of the Plan, Stock Incentives granted under the Plan shall vest no earlier than the first anniversary of the date the Stock Incentive is granted; provided, however, that, notwithstanding the foregoing: (i) Stock Incentives that result in the issuance of an aggregate of up to 5% of the shares of Common Stock available pursuant to Section 4(a) may be granted to any one or more Key Persons without respect to such minimum vesting provisions and (ii) the limitations set forth in the immediately preceding clause (i) notwithstanding, nothing herein shall preclude the Committee from taking action, in its sole discretion, to accelerate or maintain the vesting of any Stock Incentives in connection with a Key Person’s death, disability, Retirement or other termination of Service.
4. Stock Subject to this Plan.
(a)Subject to the provisions of paragraphs (b) and (c) of this Section 4 and the provisions of Section 10, the aggregate number of shares of Common Stock which may be issued or transferred pursuant to Stock Incentives (including, without limitation, Incentive Stock Options) under the Plan is 7,200,000 (plus a number of shares of Common Stock equal to the number of shares of Common Stock subject to awards outstanding under the Grace 2014 Stock Incentive Plan that are terminated, canceled, forfeited, or expire, or under which the shares otherwise cease to be issuable); provided, however, that such aggregate number of Shares available for issuance under the Plan shall be reduced by 3.19 shares of Common Stock for each share of Common Stock delivered in settlement of any Full Value Award. Authorized but unissued shares of Common Stock and issued shares of Common Stock held by the Company or a Subsidiary, whether acquired specifically for use under this Plan or otherwise, may be used for purposes of this Plan.
(b)    If any shares of Common Stock subject to a Stock Incentive that is not a Full Value Award are terminated, canceled, forfeited, or expire, or such Stock Incentive is settled for cash (in whole or in part), the shares of Common Stock subject to such Stock Incentive shall, to the extent of such termination, cancellation, forfeiture, expiration or cash settlement, again be added back to the shares of Common Stock authorized for grant under Section 4(a). To the extent that a Full Value Award is terminated, canceled, forfeited or expires or such Full Value Award is settled for cash (in whole or in part), the shares of Common Stock available under the Plan shall be increased by 3.19


shares of Common Stock for each share of Common Stock subject to such Full Value Award that is terminated, canceled, forfeited, expired or settled in cash. Notwithstanding anything to the contrary contained herein, however, the following shares of Common Stock shall not be added back to the shares of Common Stock authorized for grant under Section 4(a) and shall not be available for future grants of Stock Incentives: (i) shares of Common Stock tendered by a Key Person or withheld by the Company in payment of the exercise price of an Option; (ii) shares of Common Stock tendered by the Key Person or withheld by the Company to satisfy any tax withholding obligation with respect to a Stock Incentive; (iii) shares of Common Stock subject to a SAR that are not issued in connection with the stock settlement of the SAR on exercise thereof; and (iv) shares of Common Stock purchased on the open market with the cash proceeds from the exercise of Options. In addition, notwithstanding the other provisions of this Section 4(b), no shares of Common Stock may again be optioned, granted or awarded if such action would cause an Incentive Stock Option to fail to qualify as an incentive stock option under Section 422 of the Code.
(c)The maximum number of shares of Common Stock that may be subject to Stock Incentives granted to any one Key Person during any one calendar year shall be limited to One Million (1,000,000) shares of Common Stock (subject to adjustment as provided in Section 10). In addition, the maximum Fair Market Value (measured at the grant date) under Stock Incentives granted to any Director during any one calendar year, shall not exceed $750,000.
5. Stock Awards. Stock Incentives in the form of Stock Awards shall be subject to the following provisions:
(a)    Shares of Common Stock subject to a Stock Award may be issued to a Key Person at the time the Stock Award is granted, or at any time subsequent thereto, or in installments from time to time, subject to such terms and conditions including risks of forfeiture, as provided in the Stock Incentive Agreement. Any Stock Incentive Agreement for a Stock Award may provide that the value of any shares of Common Stock subject to such Stock Award to be issued subsequent to the grant date may be paid in cash, on each date on which shares would otherwise have been issued, in an amount equal to the Fair Market Value on such date of the shares that would otherwise have been issued.
(b)    The material terms of each Stock Award shall be determined by the Committee. Each Stock Award shall be evidenced by a written instrument consistent with this Plan. It is intended that a Stock Award would be made contingent upon the attainment of one or more specified objectives (which objectives may, for the avoidance of doubt, relate solely to the continued provisions of Service by the recipient of a Stock Award) and may be made subject to restrictions on the sale or other disposition of the Stock Award or the shares subject thereto for a period of one or more years (or such other shorter or longer period as the Committee may determine).
(c)    A Stock Award shall be granted for such lawful consideration as may be provided therein.
6. Options and SARs.Stock Incentives in the form of Options and SARs shall be subject to the following provisions:


(a)    Options. The Option exercise price per share of Common Stock shall not be less than one hundred (100%) percent of the Fair Market Value of a share of Common Stock on the date the Option is granted; and such exercise price per share of Common Stock shall not be reduced, by action of the Board of Directors or otherwise, at any time after the date the Option is granted (subject to Section 10 hereof). The exercise price and any withholding tax that may be due on the exercise of an Option may be paid in cash, or, if so provided in the Option Agreement, (i) in shares of Common Stock (including shares issued pursuant to the Option being exercised), or (ii) in a combination of cash and such shares; provided, however, that (A) no shares of Common Stock delivered in such payment may be "immature shares," as determined in accordance with generally accepted accounting principles in effect at the time, (B) any shares of Common Stock delivered to the Company in such payment shall be valued at their Fair Market Value on the date of exercise; and (C) for the avoidance of doubt, payment may be made in cash through a “cashless exercise,” to the extent permitted by applicable law, by delivering a properly executed exercise notice to the Company, together with a copy of irrevocable instructions to a broker to deliver promptly to the Company the amount of sale proceeds of shares of Common Stock otherwise deliverable under the exercised Option, as is necessary to pay the Option exercise price if applicable, and, if requested, the minimum amount of any federal, state, local or foreign withholding taxes due in respect of the Option (and to facilitate the foregoing, the Company may, to the extent permitted by applicable law, enter into agreements for coordinated procedures with one or more brokerage firms). No indication of ownership of shares of Common Stock shall be issued upon the exercise of an Option until the Option exercise price due for such shares has been paid in full and arrangements have been made for any tax withholding due in respect of the Option, as applicable.
(b)    SARs. The SAR exercise price per share of Common Stock (which is subtracted from the Fair Market Value of a share of Common Stock on the exercise date to determine the amount payable under the SAR) shall not be less than one hundred (100%) percent of the Fair Market Value of a share of Common Stock on the date the SAR is granted; and such exercise price per share of Common Stock shall not be reduced, by action of the Board of Directors or otherwise, at any time after the date the SAR is granted (subject to Section 10 hereof). Any withholding tax that may be due on the exercise of the SAR may be paid in cash or through withholding on the amounts that would otherwise be paid pursuant to the SAR.
(c)    Each Option or SAR shall be exercisable during the life ofthe holder only by the holder and, after the holder’s death, only by his or her estate or by a person who acquires the right to exercise the Option or SAR by will or the laws of descent and distribution. Unless otherwise provided in the applicable Stock Incentive Agreement, an Option or SAR, to the extent that it shall not have been exercised or canceled, shall terminate as follows after the holder ceases to serve: (i) if the holder shall voluntarily cease to serve without the consent of the Committee the Option or SAR shall terminate 45 calendar days after such cessation, (ii) if the holder shall have his service terminated for “cause”, the Option or SAR shall terminate immediately upon cessation of service; (iii) if the holder shall cease to serve by reason of death, incapacity or Retirement, the Option or SAR shall terminate three (3) years after the date on which the holder ceased to serve; and (iv) except as provided in the next sentence, in all other cases the Option or SAR shall terminate three (3) months after the date on which the holder ceased to serve unless the Committee shall approve a longer period (which approval may be given before or after cessation of service but not after termination of the Option or SAR) not to exceed three (3) years. If the holder shall die or become incapacitated during the three (3) month period (or such longer period as the Committee may approve) referred to in the preceding clause (iii), the Option or SAR shall terminate three (3) years


after the date on which he ceased to serve. A leave of absence for military or governmental service or other purposes shall not, if approved by the Committee (which approval may be given before or after the leave of absence commences but not after termination of the Option or SAR), be deemed a cessation of service within the meaning of this paragraph (c). Notwithstanding the foregoing provisions of this paragraph (c) or any other provision of this Plan, no Option or SAR shall be exercisable after expiration of a period of ten (10) years from the date the Option or SAR is granted and no Incentive Stock Option shall be exercisable after expiration of a period of ten (10) years from the date the Incentive Stock Option is granted.
(d)    No restricted stock unit, Option (including a Net Exercise Option) or SAR, nor any right thereunder, may be assigned or transferred except to Permitted Transferees, or by will or the laws of descent and distribution and except, in the case of a Nonstatutory Stock Option or SAR, pursuant to a qualified domestic relations order (as defined in the Code). Notwithstanding the forgoing, the Committee in its sole discretion, may determine to permit a Key Person or a Permitted Transferee of such Key Person to transfer an Option other than an Incentive Stock Option (unless such Incentive Stock Option is intended to become a Nonstatutory Stock Option) or SAR to any one or more Permitted Transferees of such Key Person, subject to the following terms and conditions: (i) an Option or SAR transferred to a Permitted Transferee shall not be assignable or transferable by the Permitted Transferee other than (A) to another Permitted Transferee of the applicable Key Person or (B) by will or the laws of descent and distribution or, subject to the consent of the Committee, pursuant to a qualified domestic relations order; (ii) an Option or SAR transferred to a Permitted Transferee shall continue to be subject to all the terms and conditions of the Option or SAR as applicable to the original Key Person (other than the ability to further transfer the Option or SAR to any person other than another Permitted Transferee of the applicable Key Person); (iii) any transfer of an Option or SAR to a Permitted Transferee shall be without consideration, except as required by applicable law; and (iv) the Key Person (or transferring Permitted Transferee) and the receiving Permitted Transferee shall execute any and all documents requested by the Committee, including, without limitation documents to (A) confirm the status of the transferee as a Permitted Transferee, (B) satisfy any requirements for an exemption for the transfer under applicable law and (C) evidence the transfer.
(e)    An Option may, but need not, be an Incentive Stock Option; provided, however,that (i) no Incentive Stock Option may be granted more than ten (10) years after the earlier of adoption of the Plan by the Committee or approval by the Company’s stockholders; (ii) the exercise price of any Incentive Stock Option granted to a Key Person who owns (within the meaning of Section 422(b)(6) of the Code, after the application of the attribution rules in Section 424(d) of the Code) more than ten (10%) percent of the total combined voting power of all classes of shares of stock of the Company or any parent or Subsidiary of the Company shall be not less than one hundred ten (110%) percent of the Fair Market Value of the Common Stock on the grant date and the term of such stock option shall not exceed five (5) years; (iii) the aggregate Fair Market Value (determined as of the time an Incentive Stock Option is granted) of the shares subject to each installment becoming exercisable for the first time in any calendar year under Incentive Stock Options granted (under all plans, including this Plan, of his employer corporation and its parent and subsidiary corporations) to the Key Person to whom such Incentive Stock Option is granted shall not exceed One Hundred Thousand Dollars ($100,000); (iv) Incentive Stock Options shall only be issued to Key Persons who are employees of the Company or of a Subsidiary; and (v) no Option issued under the Plan shall be an Incentive Stock Option unless the Plan is approved by the stockholders of the Company within twelve (12) months of its adoption by the Committee.


(f)    The material terms of each Option or SAR shall be determined by the Committee. Each Option or SAR shall be evidenced by a written instrument consistent with this Plan (i.e., an Option or SAR Agreement, as applicable) and, in the case of an Option, shall specify whether the Option is an Incentive Stock Option or a Nonstatutory Stock Option. An Option or SAR may include restrictions and limitations in addition to those provided for in this Plan.
(g)    Subject to the other provisions of this Section 6, Options shall be granted for such lawful consideration as may be provided for in the Option Agreement.
(h)    Subject to Section 10 hereof, without the approval of the Company’s stockholders, (i) no transaction or series of transactions shall have the effect of exchanging all or any portion of any Option or SAR granted under this Plan (any such award, a "Previously Granted Option") for, or replacing all or any portion ofany Previously Granted Option with, a new Option or SAR (as applicable), where the exercise price per share of Common Stock under the new Option or SAR is less than such exercise price applicable under the Previously Granted Option, (ii) the Committee shall not authorize the amendment of any outstanding Option or SAR to reduce its price per share of Common Stock, or (iii) the Company shall not cancel any Option or SAR in exchange for cash or another Stock Incentive when the Option or SAR exercise price per share of Common Stock exceeds the Fair Market Value of the underlying shares of Common Stock.
7.Net Exercise Options. A “Net Exercise Option” is an Option that is a Nonstatutory Stock Option, where the applicable Option Agreement specifies that the Company will reduce the number of shares issued under the Option upon exercise by the minimum whole number of shares with a Fair Market Value sufficient to pay the aggregate exercise price of the exercised shares. (If the Fair Market Value of the whole number of shares withheld exceeds the aggregate exercise price of the exercised shares, the excess fractional share shall be forfeited by the Option holder.)
8.Combination of Stock Awards, Options and/or SARs. Stock Incentives authorized by paragraph (c)(iv) of Section 3 in the form of combinations of Stock Awards, Options and/or SARs shall be subject to the following provisions:
(a)     A Stock Incentive may be a combination of any form of Stock Award and any form of Option and/or SAR; provided, however, that the terms and conditions of such a Stock Incentive pertaining to a Stock Award are consistent with Section 5 and the terms and conditions ofsuch a Stock Incentive pertaining to an Option or SAR are consistent with Section 6 and in the case of an Incentive Stock Option, the combination is not in violation of Treasury Regulations Section 1.422-5(d).
(b)    Such a combination Stock Incentive shall be subject to such other terms and conditions as may be specified therein, including, without limitation, a provision terminating, in whole or in part, a portion thereof upon the exercise in whole or in part of another portion thereof.
(c)    The material terms of each combination Stock Incentive shall be determined by the Committee. Each combination Stock Incentive shall be evidenced by a written instrument consistent with this Plan.



9.Performance Awards.

The Committee, in its discretion, shall determine the Key Persons eligible for Performance Awards, the targets for Performance Measures to be achieved during each Performance Period, and the type, amount, and terms and conditions of any Performance Awards. Performance Awards may be granted either alone or in addition to other Stock Incentives made under the Plan
10. Adjustment and Dividend Provisions. (a)In the event that any reclassification, split-up (whether by a dividend payable in Common Stock or otherwise), or consolidation of the Common Stock shall be effected, or the outstanding shares of Common Stock are, in connection with a merger or consolidation of the Company or a sale by the Company of all or a part of its assets, exchanged for a different number or class of shares of stock or other securities or property of the Company or for shares of the stock or other securities or property of any other corporation or person, then (i) the number, kind, and class of shares or other securities or property that may be issued pursuant to Stock Incentives thereafter granted, (ii) the number, kind and class of shares or other securities or property that have not been issued under outstanding Stock Incentives, (iii) the purchase price to be paid (or exercise price, in the case of Options or SARs) per share or other unit under outstanding Stock Incentives, and (iv) the price to be paid per share or other unit by the Company or a Subsidiary for shares or other securities or property issued pursuant to Stock Incentives that are subject to a right of the Company or a Subsidiary to re-acquire such shares or other securities or property; shall in each case be equitably adjusted as determined by the Committee.

(c)Dividends. In the event that a dividend or dividend equivalent is to be paid (in cash or in stock) in respect of an unvested Stock Incentive, such dividends or dividend equivalents shall be retained by the Company and shall be paid to the Key Person subject to the same restrictions and vesting as are applicable to the underlying Stock Incentive. The Company shall not pay cash dividends or dividend equivalents (in cash or in stock) on Options or SARs.

This Plan shall terminate, and no Stock Incentives shall be issued hereunder, as of the first business day on or after the ten-year anniversary of the Effective Date.
12. Administration. (a) This Plan shall be administered by the Committee, which shall have full authority to act in the matter of selection of Key Persons and in granting Stock Incentives


to them and such other authority as is granted to the Committee by this Plan. Notwithstanding any other provision of this Plan, the Board of Directors may exercise any and all powers of the Committee with respect to this Plan, except to the extent that the possession or exercise of any power by the Board of Directors would cause any Stock Incentive to become subject to, or to lose an exemption from, Section 16(b) of the Exchange Act.
(b)The Committee may establish such rules and regulations, not inconsistent with the provisions of this Plan, as it deems necessary to determine eligibility to be granted Stock Incentives under this Plan and for the proper administration of this Plan, and the Committee may amend or revoke any rule or regulation so established. The Committee may make such determinations and interpretations under or in connection with this Plan as it deems necessary or advisable. All such rules, regulations, determinations and interpretations shall be binding and conclusive upon the Company, its Subsidiaries, its stockholders and its directors, officers and employees, and upon their respective legal representatives, beneficiaries, successors and assigns, and upon all other persons claiming under or through any of them.
(c)    The Committee shall have full and final authority, which shall be exercised in its sole discretion, to accelerate wholly or partially the vesting or lapse of all forfeiture, repurchase and other restrictions on any outstanding Stock Incentives or portion thereof in connection with any Key Person’s death, disability, Retirement or termination of Service.
(d)    Members of the Board of Directors and members of the Committee acting under this Plan shall be fully protected in relying in good faith upon the advice of counsel and shall incur no liability in the performance of their duties, except as otherwise provided by applicable law.

(b)No shares of Common Stock shall be issued pursuant to a Stock Incentive unless and until all legal requirements applicable to the issuance of such shares have, in the opinion of counsel to the Company, been complied with. In connection with any such issuance, the person acquiring the shares shall, if requested by the Company, give assurances, satisfactory to counsel to the Company, in respect of such matters as the Company or a Subsidiary may deem desirable to assure compliance with all applicable legal requirements.
(c)    No person (individually or as a member of a group), and no beneficiary or other person claiming under or through him, shall have any right, title or interest in or to any shares of Common Stock allocated or reserved for the purposes of this Plan or subject to any Stock Incentive, except as to such shares of Common Stock, if any, as shall have been issued to him.
(d)    In the case of a grant of a Stock Incentive to a Key Person who is employed by a Subsidiary, such grant may provide for the issuance of the shares covered by the Stock Incentive to the Subsidiary, for such consideration as may be provided or as a contribution to the Subsidiary’s capital, upon the condition or understanding that the Subsidiary will transfer the shares to the Key Person in accordance with the terms of the Stock Incentive.


(e)    In the event the laws of a country in which the Company or a Subsidiary has employees prescribe certain requirements for Stock Incentives to qualify for advantageous tax treatment under the laws of that country (including, without limitation, laws establishing options analogous to Incentive Stock Options), the Committee, may, for the benefit of such employees, amend, in whole or in part, this Plan and may include in such amendment additional provisions for the purposes of qualifying the amended plan and Stock Incentives granted thereunder under such laws; provided, however,that (i) the terms and conditions of a Stock Incentive granted under such amended plan may not be more favorable to the recipient than would be permitted if such Stock Incentive had been granted under this Plan as herein set forth, (ii) all shares allocated to or utilized for the purposes of such amended plan shall be subject to the limitations of Section 4, and (iii) the provisions of the amended plan may restrict but may not extend or amplify the provisions of Sections 10 and 14.
(f)    The Company or a Subsidiary may make such provisions as either may deem appropriate for the withholding of any taxes that the Company or a Subsidiary determines is required to be withheld in connection with any Stock Incentive.
(g)    Nothing in this Plan is intended to be a substitute for, or shall preclude or limit the establishment or continuation of, any other plan, practice, or arrangement for the payment of compensation or benefits to directors, officers, or employees generally, or to any class or group of such persons, that the Company or any Subsidiary now has or may hereafter put into effect, including, without limitation, any incentive compensation, retirement, pension, group insurance, stock purchase, stock bonus, or stock option plan.
(h)    Stock Incentives under the Plan are intended to be either exempt from Code Section 409A or in compliance with Code Section 409A and the Plan shall be so administered and interpreted (including, for the avoidance of doubt, that (i) the exercise price per share of Common Stock of any Option or SAR shall be established (and adjusted, as applicable) in a manner that satisfies the requirements of Code Section 409A and (ii) for any Stock Incentive that constitutes “nonqualified deferred compensation” within the meaning of Code Section 409A, (x) each payment under a Stock Incentive shall be treated as a separate payment for purposes of Code Section 409A, (y) a recipient thereof shall not be considered to have experienced a cessation of service unless the recipient has experienced a “separation from service” within the meaning of Code Section 409A and (z) in the event that the recipient is a “specified employee” within the meaning of Code Section 409A (as determined in accordance with the methodology established by the Company), any such compensation that would otherwise be payable during the six-month period immediately following the recipient’s cessation of service by reason of such cessation of service shall instead be paid or provided on the first business day following the date that is six (6) months following the recipient’s cessation of service. Any Stock Award which is not intended to meet the requirements for a “short-term deferral” under Treasury Regulations Section 1.409A-1(b)(4) or is otherwise not exempt from Section 409A will be issued pursuant to an agreement that complies with Section 409A. The Committee shall take no action under the Plan that would cause a Stock Incentive under the Plan to fail to either be exempt from Code Section 409A or in compliance with Code Section 409A. Notwithstanding the foregoing, Stock Incentive recipients are solely responsible for the tax consequences to them of Stock Incentives under the Plan, including any tax consequences under Code Section 409A.
(i)Claw-Back. All Stock Incentives (including any proceeds, gains or other economic benefit actually or constructively received by a Key Person upon any receipt, vesting or exercise


of any Stock Incentive or upon the receipt or resale of any shares of Common Stock underlying the Stock Incentive) shall be subject to the provisions of any claw-back policy implemented by the Company, including, without limitation, any claw-back policy adopted to comply with the requirements of applicable law, including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder, whether or not such claw-back policy was in place at the time of grant of a Stock Incentive, to the extent set forth in such claw-back policy and/or in an applicable Stock Incentive Agreement.
(j)    Personal Data. As a condition of receipt of any Stock Incentive, each Key Person explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of personal data as described in this Section 13(j) by and among, as applicable, the Company and its Subsidiaries for the exclusive purpose of implementing, administering and managing the Key Person’s participation in the Plan. The Company and its Subsidiaries may hold certain personal information about a Key Person, including but not limited to, the Key Person’s name, home address and telephone number, date of birth, social security or insurance number or other identification number, salary, nationality, job title(s), any shares of stock held in the Company or any of its Subsidiaries, details of all Stock Incentives, in each case, for the purpose of implementing, managing and administering the Plan and Stock Incentives (the “Data”). The Company and its Subsidiaries may transfer the Data amongst themselves as necessary for the purpose of implementation, administration and management of a Key Person’s participation in the Plan, and the Company and its Subsidiaries may each further transfer the Data to any third parties assisting the Company and its Subsidiaries in the implementation, administration and management of the Plan. These recipients may be located in the Key Person’s country, or elsewhere, and the Key Person’s country may have different data privacy laws and protections than the recipients’ country. Through acceptance of an Stock Incentive, each Key Person authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing the Key Person’s participation in the Plan, including any requisite transfer of such Data as may be required to a broker or other third party with whom the Company or any of its Subsidiaries or the Key Person may elect to deposit any Shares. The Data related to a Key Person will be held only as long as is necessary to implement, administer, and manage the Key Person’s participation in the Plan. A Key Person may, at any time, view the Data held by the Company with respect to such Key Person, request additional information about the storage and processing of the Data with respect to such Key Person, recommend any necessary corrections to the Data with respect to the Key Person or refuse or withdraw the consents herein in writing, in any case without cost, by contacting his or her local human resources representative. The Company may cancel Key Person’s ability to participate in the Plan and, in the Administrator’s discretion, the Key Person may forfeit any outstanding Stock Incentives if the Key Person refuses or withdraws his or her consents as described herein. For more information on the consequences of refusal to consent or withdrawal of consent, Key Persons may contact their local human resources representative.
14.Acquisitions by the Company. If the Company or any Subsidiary should purchase stock or assets or otherwise acquire the whole or part of the business of another entity, or merge or consolidate with another entity (as part of a transaction that is not a Change in Control as defined herein), the Company, upon the approval of the Committee, (a) may assume, in whole or in part and with or without modifications or conditions, any stock incentives granted by the acquired entity to its directors, officers, employees or consultants in their capacities as such, or (b) may grant new Stock Incentives in substitution therefor. Any such assumed or substitute Stock Incentives may


contain terms and conditions inconsistent with the provisions of this Plan (including the limitations set forth in paragraph (a) of Section 4), including additional benefits for the recipient; provided, however,that if such assumed or substitute Stock Incentives are Incentive Stock Options, such terms and conditions are permitted under the plan of the acquired entity. For the purposes of any applicable plan provision involving time or a date, a substitute Stock Incentive shall be deemed granted as of the date of grant of the original stock incentive.
15.Change in Control Provisions. Unless otherwise provided in a Stock Incentive Agreement and notwithstanding any other provision of this Plan to the contrary:
(a)Stock Incentives Not Assumed. If a Change in Control occurs and a Key Person’s Stock Incentives are not continued, converted, assumed, or replaced with a substantially similar award by (i) the Company, or (ii) a successor entity or its parent or subsidiary (an “Assumption”), and provided that the Key Person has not had a termination of Service, then immediately prior to the Change in Control such Stock Incentives shall become fully vested, exercisable and/or payable, as applicable, and all forfeiture, repurchase and other restrictions on such Stock Incentives shall lapse, in which case, such Stock Incentives shall be canceled upon the consummation of the Change in Control in exchange for the right to receive the Change in Control consideration payable to other holders of Common Stock (A) which may be on such terms and conditions as apply generally to holders of Common Stock under the Change in Control documents (including, without limitation, any escrow, earn-out or other deferred consideration provisions) or such other terms and conditions as the Committee may provide, and (B) determined by reference to the number of shares subject to such Stock Incentives and net of any applicable exercise price; provided that to the extent that any Stock Incentives constitute “nonqualified deferred compensation” that may not be paid upon the Change in Control under Section 409A without the imposition of taxes thereon under Section 409A, the timing of such payments shall be governed by the applicable Stock Incentive Agreement (subject to any deferred consideration provisions applicable under the Change in Control documents); and provided, further, that if the amount to which a Key Person would be entitled upon the settlement or exercise of such Stock Incentive at the time of the Change in Control is equal to or less than zero, then such Stock Incentive may be terminated without payment. The Committee shall determine whether an Assumption of an Award has occurred in connection with a Change in Control.
(b)Stock Incentives Assumed. If a Change in Control occurs and a Key Person’s Stock Incentives are subject to Assumption, and, within twenty-four (24) months following such Change in Control (i) such Key Person’s employment or service with the Company or a successor entity or its parent or subsidiary is terminated other than for “cause” (as defined in the Stock Incentive Agreement relating to such Stock Incentive, or if such Agreement does not set forth such a definition, as such term is reasonably defined by the Committee or the successor thereto), or (ii) such Key Person voluntarily terminates his or her employment or service with the Company or a successor entity or its parent or subsidiary with “good reason” (as defined in the Stock Incentive Agreement relating to such Stock Incentive, or if such Agreement does not set forth such a definition, as such term is reasonably defined by the Committee or the successor thereto), then such Key Person’s remaining unvested Stock Incentives (including any substituted Stock Incentives) shall become fully vested, exercisable and/or payable, as applicable, and all forfeiture, repurchase and other restrictions on such Stock Incentives (including any substituted Stock Incentives) shall lapse, on the date of termination.


(c)The Committee shall take such action as it deems appropriate and equitable to effectuate the purposes of this Plan and to protect the grantees of Stock Incentives, which action may include, without limitation, any one or more of the following, provided such action is in compliance with Code Section 409A if applicable: (i) acceleration or change of the exercise and/or expiration dates of any Option or SAR to require that exercise be made, if at all, prior to the Change in Control; (ii) cancellation of any Stock Incentives upon payment to the holder in cash of the Fair Market Value of the shares subject to such Stock Incentives as of the date of (and, to the extent applicable, as established for purposes of) the Change in Control, less the aggregate exercise price, if applicable, of the Option or SAR; and (iii) in any case where equity securities of another entity are proposed to be delivered in exchange for or with respect to shares of Common Stock of the Company, arrangements to have such other entity replace the Stock Incentives granted hereunder with awards with respect to such other securities, with appropriate adjustments in the number of shares subject to, and the exercise prices under, the Stock Incentives (as applicable).
16.Amendments and Termination. (a)Anytime subsequent to the Effective Date, this Plan may be amended or terminated by the Committee; provided, however, that, without the approval of the stockholders of the Company, no amendment shall be made that (i) causes this Plan to cease to comply with applicable law; (ii) permits any person who is not a Key Person to be granted a Stock Incentive (except as otherwise provided in Section 14); (iii) increases the maximum number of shares of Common Stock that may be issued pursuant to Stock Incentives granted under this Plan (subject to the provisions of Section 4(b) and (c) and the provisions of Section 10); (iv) amends the provisions of paragraph (a) of Section 4, paragraphs (a), (b), or (e) of Section 6 to permit shares to be valued at, or to have a purchase price of, respectively, less than the percentage of Fair Market Value specified therein; (v) amends Section 11 to extend the date set forth therein; or (vi) amends this Section 16.
(b)The Committee may amend, modify or terminate any Stock Incentive Agreement, subject to applicable law and to the other provisions of this Plan including subsection (c) below.
(c)No amendment or termination of this Plan shall adversely affect any holder’s rights under any Stock Incentive previously granted to, and accepted by, the holder; and no amendment to any such Stock Incentive shall adversely affect any holder’s rights thereunder; without the consent of the holder thereof.
