2.Employee’s Continuing Obligations.

a.Release. Employee, individually, and on behalf of Employee’s heirs, executors, administrators, successors and assigns, releases and forever discharges Masco, Employer, their parents, subsidiaries, affiliates, divisions, and, as to each of the aforementioned, their respective successors, predecessors, assigns, insurers, past and present owners, officers, directors, agents, current and former employees and independent contractors, all others for whom the parties released herein may be vicariously or otherwise liable, the attorneys and legal representatives of all those released herein, as well as the agents and employees of those attorneys and legal representatives, and any and all other persons, firms, companies, corporations and other legal entities (collectively referred to as the “Released Parties”), of and from all claims, demands, actions, causes of action, statutory rights, debts, suits, contracts, agreements, and liabilities of any kind, nature or description, direct or indirect, in law or in equity, in contract or in tort or otherwise, which Employee ever had or which Employee now has or hereafter can, shall or may have, against any of the Released Parties, for or by reason of any matter, cause, or thing whatsoever up to the date Employee executes this Agreement, whether known or unknown, suspected or unsuspected at the present time, or which may be based upon pre-existing acts, claims or events occurring at any time up to the present date which may or have resulted in damages, including without limitation all direct or indirect claims either for direct or consequential damages of any kind whatsoever and rights or claims arising under any and all federal, state or local statutes, ordinances and/or laws, including without limitation Title VII of the Civil Rights Act of 1964 (“Title VII”),  the Equal Pay Act (“EPA”), the Pregnancy Discrimination Act (“PDA”), the Genetic Information Nondiscrimination Act (“GINA”), the Age Discrimination in Employment Act (“ADEA”), the Older Workers Benefit Protection Act (“OWBPA”), the Family and Medical Leave Act (“FMLA”), the Americans with Disabilities Act (“ADA”), all claims under applicable state civil rights statutes, and all other claims and rights, whether in law or equity.  It is the intention of the parties that this general release by Employee will be construed as broadly as possible, subject to the express limitations set forth below. Nothing in this Agreement, however, prohibits or prevents Employee from filing a charge with or participating, testifying or assisting in any investigation, hearing, whistleblower action or other proceeding, which cannot be waived, before any federal, state or local government agency (e.g., EEOC, NLRB, SEC, etc.), nor does anything in this Agreement preclude, prohibit or otherwise limit, in any way, Employee rights and abilities to contact, communicate with, report matters to or otherwise participate in any whistleblower program administered by any such agencies. However, to the maximum extent permitted by law, Employee agrees that if such an administrative claim is made, Employee shall not be entitled to recover any individual monetary relief or other individual remedies, except with respect to claims set forth in Paragraph 2.h. below.

any claim relating to directors’ and officers’ liability insurance coverage or any right of indemnification (including related advancement of expenses) under Masco’s or any of its affiliates’ organizational documents, an indemnification agreement with Masco or any of its affiliates or otherwise; (d) any claim to amounts owed under this Agreement (subject to its terms); or (e) Employee’s rights as an equity or security holder in Masco or its affiliates; or (f) any claims which cannot be released by private agreement, including as set forth in Paragraph 2.h. below.

b.Medicare Waiver. Employee affirms that as of the date Employee signs this Agreement, (1) Employee is not Medicare eligible (i.e., is not 65 years of age or older; is not suffering from end-stage renal failure; has not received Social Security Disability Insurance benefits for 24 months or longer, etc.) or (2) if eligible, Employee has no outstanding claims for Medicare benefits. Employee agrees to reasonably cooperate with Masco upon request with respect to any claim the CMS may make and for which Employee is required to indemnify Masco under this paragraph. Further, Employee agrees to waive any and all future actions against Masco for any private cause of action for damages pursuant to 42 U.S.C. § 1395y(b)(3)(A), except as set forth in in Paragraph 2.h. below.

The release contained herein will not release or otherwise affect the Parties’ rights and obligations arising under this Agreement.

c.Past Agreements Continue. This Agreement does not release Employee of any ongoing obligations owed to the Masco pursuant to the following agreements previously entered into with Masco:

i.Dispute Resolution Policy (DRP). Any dispute Employee might have against Released Parties, arising out of the terms of this Agreement or otherwise, will be resolved solely by use of Dispute Resolution Policy (“DRP”), the terms of which are incorporated into this Agreement. By signing this Agreement, Employee certifies that Employee has had an opportunity to review the DRP and that Employee has signed an acknowledgement of receipt of that document.

ii.Proprietary Confidential Information and Invention Assignment Agreement. Except as set forth in Paragraph 2.h. below, Employee agrees to comply with the Proprietary Confidential Information and Invention Assignment Agreement.

d.Return of Property. Employee agrees to return immediately any and all Masco property still in Employee’s possession (including any and all property of its affiliates) of whatsoever kind and character, including, without limitation, keys, documents, computer software and hardware, discs and media, and policy and procedures manuals. However, Employee may retain copies of this Agreement, any document referenced in this Agreement and any other agreement, plan, program, policy or arrangement related to Employee’s compensation, benefits or terms of employment with Masco and its affiliates, as well as contact information for Employee’s personal and professional contacts (whether or not stored on Masco or its affiliates’ computer systems or other devices); provided that Employee only uses such information consistent with his ongoing obligations to Masco.

e.Cooperation With Masco. Employee agrees that in the defense or prosecution of any pending or future claim involving Masco or any of its current or former affiliates (collectively referred to as the “Company”), Employee will be available at reasonable times for the purpose of consultation, discovery and providing testimony. Employee will at all times be candid, honest, and forthright in discharging the duties contemplated by this Paragraph. If it becomes necessary for the Company to obtain the cooperation of Employee as contemplated herein, the Company will: (i) in good faith reasonably accommodate Employee’s personal and work schedules, and (ii) reimburse reasonable expenses incurred by Employee, in connection with providing support and cooperation pursuant to this Agreement.

f.Non-Cooperation With Others. Except to the extent permitted by applicable law, or Paragraph 2.h., Employee shall not encourage or, provide any information about the business, products, or employees of the Company to any person or entity to assert, maintain, or prosecute a claim or litigation against Company or its officers, directors, or employees. Employee further agrees that, if approached informally or subpoenaed by any person, company, attorney, or agent for any person or entity other than the Company, at any time regarding any matter, currently litigated or otherwise, involving the Company, its employees, its products, or its business, Employee will give prompt notice to the General Counsel of Masco Corporation, 17450 College Parkway, Livonia, MI 48152. Masco shall reimburse Employee for any reasonable expense incurred in connection with such notification.

g.No Disparagement. Except as set forth in Paragraph 2.h. below, Employee agrees not to criticize, disparage or otherwise demean in any way Masco or its affiliates or their respective products, officers, directors or employees. This includes, but is not limited to, directly or indirectly providing disparaging comments to the media or disseminating them electronically, such as on any website or blog.

h.Employee Protection. . Notwithstanding anything to the contrary herein, Employee understands that nothing in this Agreement or otherwise restricts or prohibits Employee from initiating communications directly with, responding to any inquiries from, providing testimony before, providing information concerning this Agreement, reporting possible violations of law or regulation to, or from filing a claim or assisting with an investigation directly with a self-regulatory authority or a government agency or entity, including the Securities Exchange Commission (“SEC”) or from making other disclosures that are protected under the whistleblower provisions of state or federal law or regulation. The Company may not retaliate against the Employee for any of these activities, and nothing in this Agreement or otherwise requires Employee to waive any monetary award or other payment that Employee might become entitled to from the SEC or any other government agency or entity pursuant to this Paragraph 2.h. Nothing in this Agreement or otherwise requires Employee to disclose any communications Employee may have had or may in the future have or information Employee may have had or may in the future have provided to the SEC or any government agency or entity regarding possible legal violations. Additionally, pursuant to 18 USC § 1833(b), an individual may not be held liable under any criminal or civil federal or state trade secret law for disclosure of a trade secret: (a) made in confidence to a government official, either directly or indirectly, or to an

attorney, solely for the purpose of reporting or investigating a suspected violation of law or (b) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Additionally, an individual suing an entity for retaliation based on the reporting of a suspected violation of law may disclose a trade secret to the individual’s attorney and use the trade secret information in the court proceeding, so long as any document containing the trade secret is filed under seal and the individual does not disclose the trade secret except pursuant to court order. Nothing in this Agreement is intended to conflict with 18 USC § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by 18 USC § 1833(b).

i.Disclosure of Known Claims. Employee represents and warrants that Employee has disclosed to Masco any and all facts within Employee’s knowledge concerning any actual or potential claim against Masco, including but not limited to any and all claims arising out of federal, state or local law, or any claim resulting in or from a loss, theft or fraud against Masco, except with respect to claims set forth in Paragraph 2.h. above.

j.No Actions Filed. Employee represents that Employee has not filed any action, charge, suit, or claim against Masco with any federal, state, or local agency or court, and has not initiated any mediation or arbitration proceeding, except with respect to any action or otherwise set forth in Parapragh 2.h. above. Employee further agrees that Employee shall not receive or be entitled to any monetary damages, recovery, and/or relief of any type in connection with any charge, administrative action, or legal proceeding pursued by Employee, by any governmental agency, person, group, or entity regarding and/or relating to any claim(s) released pursuant to this Agreement, except with respect to any charge or otherwise set forth in Paragraph 2.h. above.

k.Consequence of Employee’s Breach. Employee acknowledges and agrees that if Employee breaches any obligation under this Agreement, Masco may immediately terminate any remaining payments and the provision of any other benefits that might otherwise be required by this Agreement. Any such termination by Masco shall not impair the validity or enforceability of the release provision of this Agreement.

l.Additional Relief. Employee acknowledges and agrees that Masco’s remedy at law for a breach or threatened breach of any of the following provisions of this Agreement: Employee’s Continuing Obligations, Disclosure of Known Claims, No Disparagement, , Proprietary Confidential Information and Invention Assignment Agreement, Cooperation with Masco, Non-Cooperation with Others would be inadequate and, in recognition of this fact, in the event of a breach or threatened breach of any of these provisions, Employee agrees that, in addition to its remedy at law, and at Masco’s option, all rights of Employee under Paragraph 1 of this Agreement may be terminated, and Masco shall be entitled without posting any bond to obtain, and Employee agrees not to oppose a request for, equitable relief in the form of specific performance, temporary restraining order, temporary or permanent injunction or any other equitable remedy which may then be available. Employee acknowledges that the granting of a temporary injunction, temporary restraining order or permanent injunction merely prohibiting the use of Proprietary Information would not be an adequate remedy upon breach or threatened breach hereof, and consequently agrees upon any such breach or threatened breach to the granting of injunctive relief prohibiting the design, development, manufacture, marketing or sale of products and providing of services of the kind designed, developed, manufactured, marketed, sold or provided by Masco or its affiliates as of the date of this Agreement. Nothing herein contained shall be construed as prohibiting Masco from pursuing, in addition, any other remedies available to it for such breach or threatened breach.

m.Remedies Cumulative. Employee acknowledges and agrees that the rights and remedies given to Masco in this Agreement shall be deemed cumulative, and the exercise of one such remedy shall not operate to bar the exercise of any other rights and remedies reserved to Masco or available at law or in equity.

n.Employee Acknowledgments. Employee specifically represents, warrants and confirms that, except as provided in clause (b) of this paragraph Employee: (a) has been properly paid for all hours worked for the Employer; (b) has received all bonuses and other compensation due to Employee with the exception of Employee’s final payroll check(s) for wages through and including the Separation Date, which will be paid at the time of separation; and (c) has not engaged in any unlawful conduct relating to the business of Masco.

As of the Separation Date, Employee shall cease to be an active participant under Masco’s welfare benefit and pension plans (or the plans of any of Masco’s affiliates) pursuant to the terms of those plans, and no additional benefits shall accrue to Employee. Employee waives any claim to such accrual of benefits beyond the Separation Date.
