(a) CONFIDENTIALITY. During the course of Executive’s employment with the Company, Executive will have access to Confidential Information. For purposes of this Agreement, “Confidential Information” means all data, information, ideas, concepts, discoveries, trade secrets, inventions (whether or not patentable or reduced to practice), innovations, improvements, know-how, developments, techniques, methods, processes, treatments, drawings, sketches, specifications, designs, plans, patterns, models, plans and strategies, and all other confidential or proprietary information or trade secrets in any form or medium (whether merely remembered or embodied in a tangible or intangible form or medium) whether now or hereafter existing, relating to or arising from the past, current or potential business, activities and/or operations of the Company or any of its affiliates (or any of their respective predecessors, successors or permitted assigns), including, without limitation, any such information relating to or concerning finances, sales, marketing, advertising, transition, promotions, pricing, personnel, customers, suppliers, vendors, partners and/or competitors. Executive agrees that Executive shall not, directly or indirectly, use, make available, sell, disclose or otherwise communicate to any person, other than in the course of Executive’s assigned duties and for the benefit of the Company, either during the period of Executive’s employment or at any time thereafter, any Confidential Information or other confidential or proprietary information received from third parties subject to a duty on the Company’s and its subsidiaries’ and affiliates’ part to maintain the confidentiality of such information, and to use such information only for certain limited purposes strictly for the benefit of the Company or any of its affiliates.

The terms and conditions of this Agreement shall remain strictly confidential, and Executive hereby agrees not to disclose the terms and conditions hereof to any person or entity, other than immediate family members, legal advisors or personal tax or financial advisors, or, solely for the purpose of disclosing the limitations on Executive’s conduct imposed by the provisions of this Section 9, prospective future employers who, in each case, agree to keep such information confidential. Notwithstanding the foregoing, Confidential Information shall not include any information that Executive can demonstrate (i) was lawfully in Executive’s possession prior to commencing employment with the Company or any of its predecessors, successors or affiliates and not obtained in connection with Executive’s commencement of such employment, (ii) constitutes industry knowledge or is generally available, or is made generally available, to the public other than as a result of a direct or indirect disclosure by Executive, or (iii) becomes available to Executive on a non-confidential basis from a source other than the Company or its employees, officers, affiliates, predecessors, successors or assigns.

(b) NONSOLICITATION; NONINTERFERENCE.

(i) During Executive’s employment and service with the Company and for a period of twelve (12) months thereafter, Executive agrees that Executive shall not, except in the furtherance of Executive’s duties hereunder, directly or indirectly, individually or on behalf of any other person, firm, corporation or other entity, solicit, aid or induce any individual or entity that is, or was during the twelve-month period immediately prior to the termination of Executive’s employment for any reason, a customer of the Company or any of its subsidiaries or affiliates to purchase goods or services then sold by the Company or any of its subsidiaries or affiliates from another person, firm, corporation or other entity or assist or aid any other persons or entity in identifying or soliciting any such customer.

(ii) During Executive’s employment and service with the Company and for a period of twelve (12) months thereafter, Executive agrees that Executive shall not, except in the furtherance of Executive’s duties hereunder, directly or indirectly, individually or on behalf of any other person, firm, corporation or other entity, (A) solicit, aid or induce any employee, representative or agent of the Company or any of its subsidiaries or affiliates to leave such employment or retention or solicit, aid or induce any employee of the Company or any of its subsidiaries or affiliates to accept employment with or render services to or with any other person, firm, corporation or other entity unaffiliated with the Company or hire or retain any such employee, or take any action to materially assist or aid any other person, firm, corporation or other entity in identifying, hiring or soliciting any such employee, representative or agent, or (B) interfere, or aid or induce any other person or entity in interfering, with the relationship between the Company or any of its subsidiaries or affiliates and any of their respective vendors, joint venturers or licensors. Any person described in this Section 9(c)(ii) shall be deemed covered by this Section while so employed or retained and for a period of twelve (12) months thereafter.

6

(c) NONDISPARAGEMENT. Executive agrees not to make negative comments or otherwise disparage the Company or any of its affiliates or any of their respective partners, members, officers, directors, employees, shareholders, agents or products. The foregoing shall not be violated by truthful statements in response to legal process, required governmental testimony or filings, or administrative or arbitral proceedings (including, without limitation, depositions in connection with such proceedings).

(d) INVENTIONS. Executive acknowledges and agrees that all ideas, methods, inventions, discoveries, improvements, work products, developments or works of authorship (“Inventions”), whether patentable or unpatentable, (A) that relate to Executive’s work with the Company, made or conceived by Executive, solely or jointly with others, during the Employment Term, or (B) suggested by any work that Executive performs in connection with the Company, either while performing Executive’s duties with the Company or on Executive’s own time, shall belong exclusively to the Company (or its designee), whether or not patent applications are filed thereon. Executive hereby irrevocably conveys, transfers and assigns to the Company the Inventions and all patents that may issue thereon in any and all countries, whether during or subsequent to the Employment Term, together with the right to file, in Executive’s name or in the name of the Company (or its designee), applications for patents and equivalent rights (the “Applications”). Executive will, at any time during and subsequent to the Employment Term, and at the Company’s expense, make such applications, sign such papers, take all rightful oaths, and perform all acts as may be reasonably requested from time to time by the Company with respect to the Inventions. Executive will also execute assignments to the Company (or its designee) of the Applications, and give the Company and its attorneys all reasonable assistance (including the giving of testimony) to obtain the Inventions for the Company’s benefit, all without additional compensation to Executive from the Company, but entirely at the Company’s expense. If the Company is unable for any other reason to secure Executive’s signature on any document for this purpose, then Executive hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as Executive’s agent and attorney in fact, to act for and in Executive’s behalf and stead to execute any documents and to do all other lawfully permitted acts in connection with the foregoing.

In addition, the Inventions will be deemed Work for Hire, as such term is defined under the copyright laws of the United States, on behalf of the Company and Executive agrees that the Company will be the sole owner of the Inventions, and all underlying rights therein, in all media now known or hereinafter devised, throughout the universe and in perpetuity without any further obligations to Executive. If the Inventions, or any portion thereof, are deemed not to be Work for Hire, Executive hereby irrevocably conveys, transfers and assigns to the Company, all rights, in all media now known or hereinafter devised, throughout the universe and in perpetuity, in and to the Inventions, including, without limitation, all of Executive’s right, title and interest in the copyrights (and all renewals, revivals and extensions thereof) to the Inventions, including, without limitation, all rights of any kind or any nature now or hereafter recognized, including, without limitation, the unrestricted right to make modifications, adaptations and revisions to the Inventions, to exploit and allow others to exploit the Inventions and all rights to sue at law or in equity for any infringement, or other unauthorized use or conduct in derogation of the Inventions, known or unknown, prior to the date hereof, including, without limitation, the right to receive all proceeds and damages therefrom. In addition, Executive hereby waives any so-called “moral rights” with respect to the Inventions. To the extent that Executive has any rights in the results and proceeds of Executive’s service to the Company that cannot be assigned in the manner described herein, Executive agrees to unconditionally waive the enforcement of such rights. Executive hereby waives any and all currently existing and future monetary rights in and to the Inventions and all patents that may issue thereon, including, without limitation, any rights that would otherwise accrue to Executive’s benefit by virtue of Executive being an employee of or other service provider to the Company.

Executive shall comply with all relevant agreements, policies and guidelines of the Company to which Executive is actually made aware regarding the protection of confidential information and intellectual property and potential conflicts of interest, provided the same are consistent with the terms of this Agreement and Executive’s duties to the Company and its affiliates. Executive acknowledges that the Company may amend any such policies and guidelines from time to time, and that Executive remains at all times, on or after such revision has been published to Executive, bound by their most current version.

7

The provisions of this Section 9(e) shall not apply to an Invention for which no equipment, supplies, facility, or trade secret information of the Company was used and which was developed entirely on Executive’s own time, unless (a) the invention relates (i) to the business of the Company, or (ii) to the Company’s actual or demonstrably anticipated research or development, or (b) the Invention results from any work performed by Executive for the Company.

(e) DISCLOSURE OF TRADE SECRETS. Executive understands that pursuant to the Defend Trade Secrets Act of 2016, he shall not be held criminally, or civilly, liable under any Federal or State Trade secret law for the disclosure of a trade secret that is made in confidence either directly or indirectly to a Federal, State, or local government official, or an attorney, for the sole purpose of reporting, or investigating, a violation of law. Executive further understands that employees may disclose trade secrets in a complaint, or other document, filed in a lawsuit, or other proceeding, if such filing is made under seal. Finally, Executive understands an employee who files a lawsuit alleging retaliation by the Company for reporting a suspected violation of the law may disclose the trade secret to the attorney of the employee and use the trade secret in the court proceeding, if the employee files any document containing the trade secret under seal and does not disclose the trade secret, except pursuant to court order.

(f) REASONABLENESS OF COVENANTS. In signing this Agreement, Executive has carefully read and considered all of the terms and conditions of this Agreement, including the restraints imposed under this Section 9. Executive agrees that these restraints are necessary for the reasonable and proper protection of the Company and its affiliates and their trade secrets and confidential information and that each and every one of the restraints is reasonable in respect to subject matter, length of time and geographic area, and that these restraints, individually or in the aggregate, will not prevent Executive from obtaining other suitable employment during the period in which Executive is bound by the restraints. Executive acknowledges that each of these covenants has a unique, very substantial and immeasurable value to the Company and its affiliates and that Executive has sufficient assets and skills to provide a livelihood while such covenants remain in force. Executive further covenants that Executive will not challenge the reasonableness or enforceability of any of the covenants set forth in this Section 9, and that Executive will reimburse the Company and its affiliates for all costs (including reasonable attorneys’ fees) incurred in connection with any action to enforce any of the provisions of this Section 9 if either the Company and/or any of its affiliates is the prevailing party in such dispute or if Executive challenges the reasonableness or enforceability of any of the provisions of this Section 9. It is also agreed that each of the Company’s affiliates will have the right to enforce all of Executive’s obligations to that affiliate under this Agreement and shall be third party beneficiaries hereunder, including without limitation pursuant to this Section 9. Executive acknowledges and agrees that the restrictive covenants set forth in this Agreement are independent covenants and shall be in addition to, and shall not supersede or be deemed to be in lieu of, any restrictive covenants set forth in any other agreement between Executive and the Company or its affiliates, including, without limitation, any restrictive covenants set forth in any equity-based incentive plan or grant agreement.

(g) REFORMATION. If it is determined by a court of competent jurisdiction in any state that any restriction in this Section 9 is excessive in duration or scope or is unreasonable or unenforceable under applicable law, it is the intention of the parties that such restriction may be modified or amended by the court to render it enforceable to the maximum extent permitted by the laws of that state.

(h) TOLLING. In the event of any violation of the provisions of this Section 9, Executive acknowledges and agrees that the post-termination restrictions contained in this Section 9 shall be extended by a period of time equal to the period of such violation, it being the intention of the parties hereto that the running of the applicable post-termination restriction period shall be tolled during any period of such violation.

8

(i) SURVIVAL OF PROVISIONS. The obligations contained in Sections 9 and 11 hereof shall survive the termination or expiration of the Employment Term, the non-renewal of this Agreement and Executive’s employment with the Company and shall be fully enforceable thereafter.

10. COOPERATION. Upon the receipt of reasonable notice from the Company (including outside counsel), Executive agrees that while employed by the Company and thereafter, Executive will respond and provide information with regard to matters in which Executive has knowledge as a result of Executive’s employment with the Company, and will provide reasonable assistance to the Company, its affiliates and their respective representatives in defense of any claims that may be made against the Company or its affiliates, and will reasonably assist the Company and its affiliates in the prosecution of any claims that may be made by the Company or its affiliates, to the extent that such claims may relate to the period of Executive’s employment with the Company (collectively, the “Claims”), provided, however that in no event shall Executive be required to (a) waive his U.S. constitutional rights or privileges, (b) cooperate in connection with a Claim brought by the Company against Executive or a Claim brought by Executive against the Company, or (c) disclose confidential information of any third party which Executive is legally bound to maintain as confidential.

In exchange for the foregoing, the Company agrees to reimburse Executive for all reasonable out of pocket expenses incurred by Executive in providing such cooperation including, but not limited, to mileage, air travel, hotel and food expenses along with compensation for Executive’s time if no longer employed by the Company at a rate of $200.00 per hour; provided that no such compensation payment shall be required by the Company under this Section 10 during the Employment Term or during any period in which severance is being paid to Executive pursuant to Section 7(d) hereof. Executive agrees to promptly inform the Board if Executive becomes aware of any lawsuits involving Claims that may be filed or threatened against the Company or its affiliates. During the Employment Term, Executive also agrees to promptly inform the Board (to the extent that Executive is legally permitted to do so) if Executive is asked to assist in any investigation of the Company or its affiliates (or their actions) or another party attempts to obtain information or documents from Executive (other than in connection with any litigation or other proceeding in which Executive is a party-in-opposition) with respect to matters Executive believes in good faith to relate to any investigation of the Company or its affiliates, in each case, regardless of whether a lawsuit or other proceeding has then been filed against the Company or its affiliates with respect to such investigation, and shall not do so unless legally required. During the pendency of any litigation or other proceeding involving Claims, Executive shall not communicate with anyone (other than Executive’s attorneys and tax and/or financial advisors and except to the extent that Executive determines in good faith is necessary in connection with the performance of Executive’s duties hereunder) with respect to the facts or subject matter of any pending or potential litigation or regulatory or administrative proceeding involving the Company or any of its affiliates without giving prior written notice to the Board or the Company’s counsel.

11. RETURN OF COMPANY PROPERTY. On the date of Executive’s termination of employment with the Company for any reason (or at any time prior thereto at the Company’s request), Executive shall return all Confidential Information or other property belonging to the Company or any of its affiliates (including, but not limited to, any Company-provided laptops, computers, cell phones, wireless electronic mail devices or other equipment, or documents and property belonging to the Company).

12. EQUITABLE RELIEF AND OTHER REMEDIES. Executive acknowledges and agrees that the Company’s remedies at law for a breach or threatened breach of any of the provisions of Section 9 or Section 10 hereof would be inadequate and, in recognition of this fact, Executive agrees that, in the event of such a breach or threatened breach, in addition to any remedies at law, the Company shall be entitled to obtain equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent injunction or any other equitable remedy which may then be available, without the necessity of showing actual monetary damages or the posting of a bond or other security. In the event of a violation by Executive of Section 9 or 10 hereof, any severance or other benefits being paid or provided to Executive and/or Executive’s dependents pursuant to this Agreement or otherwise shall immediately cease, and any severance previously paid to Executive shall be immediately repaid to the Company.

In that context, and without limiting the generality of the foregoing, each of the parties hereto irrevocably and unconditionally (a) submits in any proceeding relating to this Agreement or Executive’s employment by the Company or any affiliate, or for the recognition and enforcement of any judgment in respect thereof (a “Proceeding”), to the exclusive jurisdiction of the courts of the State of Massachusetts, the court of the United States of America for the District of Massachusetts and appellate courts having jurisdiction of appeals from any of the foregoing, and agrees that all claims in respect of any such Proceeding shall be heard and determined in such Massachusetts State court or, to the extent permitted by law, in such federal court, (b) consents that any such Proceeding may and shall be brought in such courts and waives any objection that Executive or the Company may now or thereafter have to the venue or jurisdiction of any such Proceeding in any such court or that such Proceeding was brought in an inconvenient court and agrees not to plead or claim the same, (c) WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR EXECUTIVE’S EMPLOYMENT BY THE COMPANY OR ANY AFFILIATE OF THE COMPANY, OR EXECUTIVE’S OR THE COMPANY’S PERFORMANCE UNDER, OR THE ENFORCEMENT OF, THIS AGREEMENT, (d) agrees that service of process in any such Proceeding may be effected by mailing a copy of such process by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such party at Executive’s or the Company’s address as provided in Section 14 hereof, and (e) agrees that nothing in this Agreement shall affect the right to effect service of process in any other manner permitted by the laws of the State of Massachusetts.

19. MISCELLANEOUS. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing and signed by Executive and such officer or director as may be designated by the CEO. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. This Agreement together with all exhibits hereto sets forth the entire agreement of the parties hereto in respect of the subject matter contained herein and supersedes any and all prior agreements or understandings between Executive and the Company with respect to the subject matter hereof; provided that in the event that Executive becomes a party to any other agreement providing for restrictive covenants similar to Section 9, such agreement shall also apply pursuant to its terms. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in this Agreement.

20. REPRESENTATIONS. Executive represents and warrants to the Company that (a) Executive has the legal right to enter into this Agreement and to perform all of the obligations on Executive’s part to be performed hereunder in accordance with its terms, and (b) Executive is not a party to any agreement or understanding, written or oral, and is not subject to any restriction, which, in either case, could prevent Executive from entering into this Agreement or impede Executive from performing all of Executive’s duties and obligations hereunder.

21. TAX MATTERS.

(a) WITHHOLDING. The Company may withhold from any and all amounts payable under this Agreement or otherwise such federal, state and local taxes as may be required to be withheld pursuant to any applicable law or regulation.

(b) SECTION 409A COMPLIANCE.

(i) The intent of the parties is that payments and benefits under this Agreement comply with, or meet the requirements of an exemption under Internal Revenue Code Section 409A and the regulations and guidance promulgated thereunder (collectively “Code Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted and construed consistent with that intent. In no event whatsoever shall the Company be liable for any additional tax, interest or penalty that may be imposed on Executive by Code Section 409A or damages for failing to comply with Code Section 409A.

(ii) A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” Notwithstanding anything to the contrary in this Agreement, if Executive is deemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered deferred compensation under Code Section 409A payable on account of a “separation from service,” such payment or benefit shall not be made or provided until the date which is the earlier of (A) the expiration of the six (6)-month period measured from the date of such “separation from service” of Executive, and (B) the date of Executive’s death, to the extent required under Code Section 409A. Upon the expiration of the foregoing delay period, all payments and benefits delayed pursuant to this Section 21(b)(ii) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to Executive in a lump sum, and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

(iii) To the extent that reimbursements or other in-kind benefits under this Agreement constitute “nonqualified deferred compensation” for purposes of Code Section 409A, (A) all such expenses or other reimbursements hereunder shall be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by Executive, (B) any right to such reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (C) no such reimbursement, expenses eligible for reimbursement, or in-kind benefits provided in any taxable year shall in any way affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year.

(iv) For purposes of Code Section 409A, Executive’s right to receive any installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within the specified period shall be within the sole discretion of the Company.

(v) Notwithstanding any other provision of this Agreement to the contrary, in no event shall any payment under this Agreement that constitutes “nonqualified deferred compensation” for purposes of Code Section 409A be subject to offset by any other amount unless otherwise permitted by Code Section 409A.
