Examples of the claims which Sekmakas is giving up by signing this Agreement include, but are not limited to, claims for breach of express or implied contracts, claims of intentional wrongdoing, claims for negligent or reckless wrongdoing, and claims for violation of any federal, state or local law, including laws prohibiting employment discrimination, such as, for example, the federal Age Discrimination in Employment Act (which is referred to hereafter as the “ADEA”).

By signing this Agreement, Sekmakas does not release or give up his right to: (i) file a charge of discrimination with the U.S. Equal Employment Opportunity Commission (“EEOC”) or the Pennsylvania Human Relations Commission (“PHRC”), (ii) file a complaint with any other government agency charged with enforcing any law, (iii) provide assistance or participate in any investigation or hearing conducted by the EEOC, PHRA or any other government agency charged with enforcing any law, (iv) file a lawsuit to challenge whether or not the release in this Paragraph 5 is a valid and effective as to claims of age discrimination under the ADEA, (v) file a lawsuit to enforce this Agreement, or (vi) assert claims that by law cannot be released, like workers’ compensation claims and claims pursuant to any vested retirement, health or benefit plans maintained by PPG including, but not limited to, benefits under PPG Industries, Inc.’s Qualified and Non-Qualified Retirement Plans, the Restricted Stock Unit Award Agreements, Non-Qualified Stock Option Award Agreements, TSR Share Agreements between Sekmakas and PPG, Deferred Compensation Plans and Long-Term Incentive Plans. If a charge of discrimination is filed with the EEOC or PHRA, however, the release in this Paragraph 5 means that Sekmakas will not be entitled to receive any money or other individual remedy as a result of that charge. By signing this Agreement, Sekmakas also gives up his right to raise claims under and/or pursue relief through PPG’s dispute resolution process known as “Resolve.”

6. RELEASE AND WAIVER OF CLAIMS BY PPG

7.    RETURN OF COMPANY PROPERTY

8.    NON-DISCLOSURE OF CONFIDENTIAL INFORMATION

“Confidential Information”, as used in this Agreement, means any non-public information, disclosed to or known by Sekmakas as a consequence of or through his employment with PPG and/or any predecessor company whose assets and/or stock PPG acquired (including information conceived, originated, discovered or developed by Sekmakas), which information is not generally known in the trade or industry about PPG’s or another company’s products, pricing, costs, margins, volumes, market share, equipment, customers, personnel, business plans, operations, processes and services, including information relating to research, strategy, development, technology, formulations, raw materials, manufacturing, purchasing, accounting, human resources, engineering, marketing, and sales.

Sekmakas will not at any time in the future use for his personal benefit or disclose to any other person or entity, any Confidential Information without PPG’s express written consent.Nothing in this Paragraph 8 will be construed to prohibit a disclosure that is required by law, or to prohibit Sekmakas from making a report that is protected by law; provided, however, that to the extent permitted by law, Sekmakas will give PPG as much advance notice

as possible before such disclosure is made so that PPG may take legally permitted steps to protect the Confidential Information as may be necessary. Sekmakas understands that he may not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret or other Confidential Information that: (a) is made (i) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (b) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding.

9.    NON-COMPETITION AND NON-SOLICITATION

(a) From the Effective Date of this Agreement (defined below) through December 31, 2018 (the “Restricted Period”):

(i) Sekmakas shall provide a copy of Paragraphs 8 and 9 of this Agreement to any prospective new employer that is a Competitor, prior to accepting employment with that Competitor.

(ii) Sekmakas shall not accept employment with, or serve as a consultant, advisor or in any other capacity to, a Competitor.

(iii) "Competitor", as used in this Agreement, means any person or entity that is engaged in, or that has plans to become during the Restricted Period engaged in the manufacture, marketing, development or sale of products or services that are the same as, or serve a substantially similar purpose or function as, the products or services that were manufactured, marketed, developed or sold by PPG or any of its subsidiaries or affiliates, or about which Sekmakas received Confidential Information, at any time during the last 24 months preceding the Effective Date of this Agreement.

(b) During the Restricted Period, Sekmakas shall not solicit for employment or hire, or influence another to solicit for employment or hire, any person who is then employed by PPG or

any of its affiliate or subsidiary companies in Band E or above or in a professional R&D position, or any person who had been so employed within six months from any such solicitation or hire.

(c) This Paragraph 9 shall supersede otherwise applicable provisions under the “Continuing Conditions” section of Sekmakas’ RSU and TSR Award Agreements and the “Forfeiture” provisions of his Stock Option Award Agreements, insofar as those provisions pertain to Sekmakas’ employment with, or service as an consultant, advisor or in any other capacity to, a competitor.

(a) Sekmakas agrees that, unless required to do so by legal process, he will not make any disparaging statements to any current, former or potential customers, contractors, vendors or employees of PPG, to any media or to any other person about PPG. A disparaging statement is any communication which, if publicized to another, would be reasonably expected to cause or tend to cause the recipient of the communication to question the business condition, integrity, competence, good character or product quality of the person or entity to whom or to which the communication relates. Nothing in this paragraph shall be construed as prohibiting Sekmakas from disclosing information as may be required as part of an investigation by a government agency charged with enforcing any law.

(b) PPG agrees that, unless required to do so by legal process, Michael McGarry and Herve Tiberghien will not make any disparaging statements to any person not employed by PPG or on its Board of Directors, including (for example) prospective employers of Sekmakas, about Sekmakas.

to whom the communication relates. PPG further agrees that Michael McGarry will instruct the members of the Executive Committee to not make disparaging statements about Sekmakas.

11.    VOLUNTARY AGREEMENT

Sekmakas acknowledges and agrees that he has entered into this Agreement voluntarily and that no person has made any promises to him to induce him to sign this Agreement other than promises that are contained in this Agreement itself.

Sekmakas acknowledges and agrees that the Release and Waiver of rights and claims as set forth in this Agreement are in exchange for valuable consideration which he would not otherwise be entitled to receive but for this Agreement.

Sekmakas acknowledges and agrees that he has carefully read and fully understands the provisions of this Agreement, including the release and waiver of claims, that he has had the opportunity to take at least twenty-one (21) days from September 8, 2017, to decide whether he wants to sign this Agreement, and that no one has pressured him to sign the Agreement sooner.
