Notwithstanding anything in this Section 2(b), Company may at any point terminate Executive’s employment for Cause prior to the effective date of any other termination contemplated hereunder.

(c)     Definition of “Disability” . For purposes of this Agreement, “Disability” shall mean as a result of Executive’s incapacity or inability, Executive’s failure to have performed Executive’s duties and responsibilities as contemplated herein for one hundred twenty (120) business days or more within any one (1) year period (cumulative or consecutive), because Executive’s physical or mental health has become so impaired as to make it impossible or impractical for Executive to perform the duties and responsibilities contemplated hereunder. Determination of Executive’s physical or mental health shall be determined by Company after consultation with a medical expert appointed by mutual agreement between Company and Executive who has examined Executive. Executive hereby consents to such examination and consultation regarding Executive’s health and ability to perform as aforesaid.

(d)     Definition of “Cause” . As used herein, “Cause” shall include: (i) Executive’s willful engagement in dishonesty, illegal conduct or gross misconduct, which is, in each case,

2

materially injurious to Company or any affiliate; (ii) Executive’s refusal to follow the legal direction of the CEO; (iii) Executive’s failure to attempt in good faith to perform his duties; (iv) Executive’s unauthorized disclosure of confidential information; (v) Executive’s embezzlement, misappropriation or fraud, whether or not related to Executive’s employment with Company; (vi) Executive’s conviction of, or pleading guilty or nolo contendere to, a felony or another crime involving moral turpitude; or (vii) Executive’s breach of a material provision of any employment, non-disclosure, invention assignment, non-competition, or similar agreement between Executive and Company, where such breach is due to intentional conduct or gross negligence of Executive. In all cases, Company shall provide Executive with written notice of the specific conduct or events that Company believes constitutes Cause and, in case of (ii), (iii), and (vii) above, if such circumstance is capable of being cured, Executive shall have thirty (30) days to effect a cure of the claimed conduct or events.

For purposes of clarification, the above-listed conditions shall apply separately to each occurrence of Good Reason and failure to adhere to such conditions in the event of Good Reason shall not disqualify Executive from asserting Good Reason for any subsequent occurrence of Good Reason. For purposes of this Agreement, “Good Reason” shall be interpreted in a manner, and limited to the extent necessary, so that it is treated as an “involuntary termination” with respect to Section 409A (“Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”), and any successor statute, regulation and guidance thereto.

3.     Compensation .

(a)     Base Salary . Company shall pay Executive a base salary (the “Base Salary”) at the annual rate of Four Hundred and Thirty Thousand Dollars ($430,000).

The amount of the Annual Performance Bonus shall be determined by the Board or an appropriate committee thereof in its sole discretion, and will be targeted for payment to Executive no later than March 15 ^th of the calendar year immediately following the calendar year in which it was earned. Executive must be employed by Company on the last day of the fiscal year in which the Annual Performance Bonus is earned in order to be eligible for, and to be deemed as having earned, such Annual Performance Bonus. Company shall deduct from the Annual Performance Bonus all amounts required to be deducted or withheld under applicable law or under any employee benefit plan in which Executive participates.

(c)     Sign On Bonus . Executive shall be eligible to receive a guaranteed sign on bonus equal to forty percent (40%) of his Base Salary (the “Sign On Bonus”), prorated based on the number of days in 2017 during the period commencing on January 1, 2017 and ending on the Commencement Date, which shall be paid to Executive on or before March 15, 2018; provided , however, that Executive shall not be entitled to receive the Sign On Bonus if his employment with Company is voluntarily terminated by him for any reason other than Good Reason or involuntarily terminated by Company for Cause prior to the date the Sign On Bonus is paid to him. Company shall deduct from the Sign On Bonus all amounts required to be deducted or withheld under applicable law or under any employee benefit plan in which Executive participates.

(d)     Reimbursement of Prior Employer Clawback .

Subject to the provisions of this Section 3(d), Company agrees to reimburse Executive for up to $15,000 (less any required withholdings or taxes) of any amount he is required to repay to his prior employer, provided that Executive provides written documentation showing the amount repaid by Executive, in a form satisfactory to Company. Executive understands and agrees that in order to receive any reimbursement pursuant to this Section 3(d), he must submit such written documentation to Company no later than December 31, 2017. Company shall pay any reimbursements due pursuant to this Section 3(d) within thirty (30) days of the date it receives the required written documentation from Executive.

(e)     Equity . Subject to approval of the Board or an appropriate committee thereof, Company shall grant Executive on the Commencement Date or as soon as practicable thereafter, pursuant to the terms of the Pulmatrix, Inc. 2013 Employee, Director and Consultant Equity Incentive Plan (the “Plan”), an option to purchase 360,000 shares of common stock of Company at a per share exercise price equal to the Fair Market Value (as defined in the Plan) of

4

Company’s common stock on the date of grant, which option shall be, to the maximum extent permissible, treated as an “incentive stock option” within the meaning of Section 422 of the Code. Twenty five percent (25%) of the shares subject to the option shall vest on the first (1 ^st ) anniversary of the Commencement Date, and the remaining Seventy Five Percent (75%) of the shares shall vest in equal installments on the last day of each of the thirty six (36) successive months thereafter, provided that Executive remains employed by Company on the vesting date, except as otherwise set forth herein or in the Plan. The option shall be evidenced in writing by, and subject to the terms and conditions of, the Plan and Company’s standard form of stock option agreement, which agreement shall expire ten (10) years from the date of grant except as otherwise provided in the stock option agreement or the Plan.

Company further agrees to grant Executive, within thirty (30) days of the closing of a Company Financing Event, an additional grant of options with respect to the common stock of Company, in an amount determined by the Compensation Committee of the Board (the “Committee”) in its sole discretion, at a per share exercise price equal to the Fair Market Value of Company’s common stock on the date of grant, provided that Executive is employed by Company on the date of grant. The actual number of options grant shall be determined by the Committee, in its sole discretion, and any award options shall be subject to the terms and conditions of the Plan, and a form of stock option award agreement, which terms shall include, without limitation, vesting of twenty-five (25%) of the options on the first (1 ^st ) anniversary of the closing date of the Company Financing Event, and the remaining seventy-five percent (75%) of the options vesting in equal installments on the last day of each of the thirty-six (36) successive months thereafter, provided that Executive remains employed by Company on each such vesting date. To the maximum extent permissible, such additional options shall be granted as “incentive stock options” within the meaning of Section 422 of the Code. For purposes of this section, a “Company Financing Event” means the closing of a transaction or the closing of the last of a series of transactions with third party investors where Company raises an aggregate of at least $15 million from such investors.

As used herein, a “Change of Control” shall mean the occurrence of any of the following events: (i)  Ownership . Any “Person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) becomes the “Beneficial Owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of Company representing fifty percent (50%) or more of the total voting power represented by Company’s then outstanding voting securities (excluding for this purpose any such voting securities held by Company, or any affiliate, parent or subsidiary of Company, or by any employee benefit plan of Company) pursuant to a transaction or a series of related transactions which the Board does not approve; or (ii)  Merger/Sale of Assets . (A) A merger or consolidation of Company whether or not approved by the Board, other than a merger or consolidation which would result in the voting securities of Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or the parent of such corporation) at least fifty percent (50%) of the total voting power represented by the voting securities of Company or such surviving entity or parent of such corporation, as the case may be, outstanding immediately after such merger or consolidation; (B) the sale or disposition by Company of all or substantially all of Company’s assets; or (iii)  Change in Board Composition . A change in the composition of the Board, as a result of which fewer than a majority of the directors are Incumbent Directors. “Incumbent Directors” shall mean directors who either (A) are directors of Company as of the Commencement Date, or (B) are elected, or nominated for election, to the Board with the affirmative votes of at least a majority of the Incumbent Directors, or by a committee of the Board made up of at least a majority of the Incumbent Directors, at the time of such election or nomination (but shall not include an individual whose election or nomination is in connection with an actual or threatened proxy contest relating to the election of directors). Notwithstanding the foregoing, no event shall constitute a Change of Control unless it would also be a “change of control” within the meaning of Section 409A of the Code and the regulations issued thereunder.

(e)     Execution of Release of Claims . Company shall not be obligated to pay Executive any of the severance payments or benefits described in this Section 4 unless and until Executive has executed (without revocation) a timely release of claims in a form that is acceptable to Company, which must be provided to Executive within fifteen (15) days following separation from service, and signed by Executive and returned to Company no later than sixty (60) days following Executive’s separation from service (the “Review Period”), and which shall include a general release of claims against Company and its affiliated entities and each of their officers, directors, employees and others associated with Company and its affiliated entities. If Executive fails or refuses to return such agreement within the Review Period, Executive’s severance payments hereunder and benefits shall be forfeited.

(f)     No Other Payments or Benefits Owing . The payments and benefits set forth in this Section 4 shall be the sole amounts owing to Executive upon termination of Executive’s employment for the reasons set forth above and Executive shall not be eligible for any other

9

payments or other forms of compensation or benefits, except with regard to indemnification in Section 3(j). The payments and benefits set forth in Section 4 shall be the sole remedy, if any, available to Executive in the event that Executive brings any claim against Company relating to the termination of Executive’s employment under this Agreement.

5.      Prohibited Competition And Solicitation . Executive expressly acknowledges that: (a) there are competitive and proprietary aspects of the business of Company; (b) during the course of Executive’s employment, Company shall furnish, disclose or make available to Executive confidential and proprietary information (“Confidential Information”) and may provide Executive with unique and specialized training; (c) such Confidential Information and training have been developed and shall be developed by Company through the expenditure of substantial time, effort and money, and could be used by Executive to compete with Company; and (d) in the course of Executive’s employment, Executive shall be introduced to customers and others with important relationships to Company, and any and all “goodwill” created through such introductions belongs exclusively to Company, including, but not limited to, any goodwill created as a result of direct or indirect contacts or relationships between Executive and any customers of Company. In light of the foregoing acknowledgements, and as a condition of employment hereunder, Executive agrees to execute and abide by Company’s Confidentiality, Assignment of Inventions and Non-Competition Agreement.

6.      Property and Records .

Executive may retain his address books to the extent that they only contain contact information.

7.     Code Sections 409A and 280G .

(a)    In the event that the payments or benefits set forth in Section 4 of this Agreement constitute “non-qualified deferred compensation” subject to Section 409A, then the following conditions apply to such payments or benefits:

(i)    Any termination of Executive’s employment triggering payment of benefits under Section 4 must constitute a “separation from service” under Section 409A(a)(2)(A)(i) of the Code and Treas. Reg. §1.409A-1(h) before distribution of such benefits can commence. To the extent that the termination of Executive’s employment does not constitute a separation of service under Section 409A(a)(2)(A)(i) of the Code and Treas. Reg. §1.409A-1(h) (as the result of further services that are reasonably anticipated to be provided by Executive to Company at the time Executive’s employment terminates), any such payments under Section 4 that constitute deferred compensation under Section 409A shall be delayed until after the date of a subsequent event constituting a separation of service under Section 409A(a)(2)(A)(i) of the Code and Treas. Reg. §1.409A-1(h). For purposes of clarification, this Section 7(a) shall not cause any forfeiture

10

of benefits on Executive’s part, but shall only act as a delay until such time as a “separation from service” occurs. In the event the time period for the return of any release of claims described in Section 4 ends in the calendar year following the year during which the termination or separation from service occurred, then the payments under Section 4 with respect to such termination or separation from service will commence in such subsequent calendar year; provided further that if such payments commence in such subsequent year, the first such payment shall be a lump sum in an amount equal to the payments that would have come due since Executive’s separation from service.

(ii)    Notwithstanding any other provision with respect to the timing of payments under Section 4 if, at the time of Executive’s termination, Executive is deemed to be a “specified employee” of Company (within the meaning of Section 409A(a)(2)(B)(i) of the Code), then limited only to the extent necessary to comply with the requirements of Section 409A, any payments to which Executive may become entitled under Section 4 which are subject to Section 409A (and not otherwise exempt from its application) shall be withheld until the first (1 ^st ) business day of the seventh (7 ^th ) month following the termination of Executive’s employment, at which time Executive shall be paid an aggregate amount equal to the accumulated, but unpaid, payments otherwise due to Executive under the terms of Section 4.

(b)    It is intended that each installment of the payments and benefits provided under Section 4 of this Agreement shall be treated as a separate “payment” for purposes of Section 409A. Neither Company nor Executive shall have the right to accelerate or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A.

(c)    Notwithstanding any other provision of this Agreement to the contrary, this Agreement shall be interpreted and at all times administered in a manner that avoids the inclusion of compensation in income under Section 409A, or the payment of increased taxes, excise taxes or other penalties under Section 409A. The parties intend this Agreement to be in compliance with Section 409A. Executive acknowledges and agrees that Company does not guarantee the tax treatment or tax consequences associated with any payment or benefit arising under this Agreement, including but not limited to consequences related to Section 409A.

(d)    If any payment or benefit Executive would receive under this Agreement, when combined with any other payment or benefit Executive receives (for purposes of this section, a “Payment”) would: (i) constitute a “parachute payment” within the meaning of Section 280G the Code; and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be either: (A) the full amount of such Payment; or (B) such lesser amount as would result in no portion of the Payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local employments taxes, income taxes and the Excise Tax, results in Executive’s receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. With respect to subsection (B), if there is more than one method of reducing the payment as would result in no portion of the

11

Payment being subject to the Excise Tax, then Executive shall determine which method shall be followed, provided that if Executive fails to make such determination within thirty (30) days after Company has sent Executive written notice of the need for such reduction, Company may determine the amount of such reduction in its sole discretion.

8.     Mediation/Dispute Resolution/Governing Law .

(a)    Subject to Section 8(c) below, in the event of a dispute regarding any of the terms and conditions of this Agreement, or otherwise relating to Executive’s employment with Company, either party may request that the other party engage in a mediation to resolve such dispute. If such request is made, the other party shall respond in writing by no later than seven (7) business days thereafter, stating whether such other party is willing to participate in such mediation, and such mediation shall occur within thirty (30) days following such notification. If the parties are unable to agree to a mediator, then the matter shall be submitted to the mediation program conducted by the American Arbitration Association in Boston, Massachusetts, and a mediator shall be selected pursuant to the rules applicable to such program.

(b)    Subject to Section 8(c) below, in the event that the other party declines to participate in a mediation, either party may require that the dispute be submitted to binding arbitration, and in such event the dispute shall be settled by arbitration in accordance with the National Rules for the Resolution of Employment Disputes of the American Arbitration Association, except that both parties agree that the matter shall be submitted to and resolved by a single arbitrator. Such arbitration shall occur in Boston, Massachusetts. Each party hereby agrees to a speedy hearing upon the matter in dispute, and the judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof.    Notwithstanding anything to the contrary in the rules cited above, and unless prohibited by applicable law: (i) the costs and expenses of the arbitration, including the arbitrator’s fees and expenses, shall be evenly split between the parties; (ii) each party shall pay for and bear the cost of his or its own experts, evidence and counsel; and (iii) no award of punitive damages may be rendered by the arbitrator in such proceedings.

(c)    Notwithstanding the foregoing, Company and Executive expressly acknowledge and agree that Company retains the right, and nothing herein shall be deemed to limit Company’s right, to seek immediate judicial relief (including injunctive relief) in a court of competent jurisdiction in the event of a claimed breach by Executive of obligations under this Agreement, the Confidentiality, Assignment of Inventions and Non-Competition Agreement, or other agreement, where such breach is related to non-competition, non-solicitation, non-disclosure and/or intellectual property, without the need to submit to arbitration or post any bond or other financial guarantee in such court action.
