To revoke this Release, the Executive must send written notification of such revocation, via facsimile or nationally-recognized overnight courier, to Christine Miller, Associate General Counsel of ArcLight at 200 Clarendon St., 55th Floor, Boston, MA 02116 or by e-mail at ***@***.

6. 18 U.S.C. § 1833(b) provides: “An individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret 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 filed in a lawsuit or other proceeding, if such filing is made under seal.” Nothing in this Release is intended to conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by 18 U.S.C. § 1833(b). Accordingly, the Executive and the parties to the Agreement have the right to disclose in confidence trade secrets to federal, state, and local

government officials, or to an attorney, for the sole purpose of reporting or investigating a suspected violation of law. The parties also have the right to disclose trade secrets in a document filed in a lawsuit or other proceeding, but only if the filing is made under seal and protected from public disclosure

7.    Construction. As used in this Release, the connectives “and,” “or,” and “and/or” shall be construed either disjunctively or conjunctively as necessary to bring within the scope of a sentence or clause all subject matter that might otherwise be construed to be outside of its scope. The words “herein,” “hereof,” “hereunder,” and other compounds of the word “here” shall refer to the entire Release, and not to any particular provision hereof. Wherever the context so requires, the masculine gender includes the feminine or neuter, and the singular number includes the plural, and vice-versa. The use herein of the word “including” following any general statement, term, or matter shall not be construed to limit such statement, term, or matter whether or not non-limiting language (such as “without limitation,” “but not limited to,” or words of similar import) is used. Neither this Release nor any uncertainty or ambiguity herein shall be construed or resolved against any party hereto, whether under any rule of construction or otherwise, regardless of which party may have drafted any particular term or provision hereof. On the contrary, this Release has been reviewed by each of the parties hereto and shall be construed and interpreted according to the ordinary meaning of the words used so as to fairly accomplish the purposes and intentions of the parties as reflected herein.

8.    Once this Release is executed, facsimile, PDF, and other true and accurate copies of this Release shall have the same force and effect as originals hereof.

Any disputes that arise in connection with this Release shall be resolved in accordance with Section 7.14 of the Employment Agreement.
