Dear Mike:


 


Quanterix Corporation (the “Company”) is pleased
to offer you the full-time position of Chief Financial Officer and Treasurer, reporting to me. Your start date will be on or before July
12, 2021. We are excited about the prospect of you joining our team.


 


1.                 
Base Salary: The Company will pay you a salary at an annual rate of $415,000.00, paid at a bi-weekly rate of $15,961.54,
subject to periodic review and adjustment at the discretion of the Company.


 


2.                 
Bonus: You will be eligible to receive an annual performance bonus beginning with the Company’s 2021 performance
year. Your annual bonus target will be up to $210,000.00 (the “Target Bonus”). The actual amount earned will be subject
to the achievement of the metrics and goals established by the Company. The annual bonus will be subject to approval by and adjustment
at the discretion of the Company, and the terms of any applicable bonus plan or award. Your 2021 bonus target will be determined based
on your actual base salary earned during the year.


 


3.                 
Benefits: You will be eligible to participate in the employee benefits and insurance programs generally made available to
its full-time employees, including medical insurance, dental insurance, 401K Plan and match, ESPP, Flexible Spending Account, term life

Sign-On Equity Award: You will be eligible to receive a sign-on equity award consisting of 5,530 restricted stock units

first anniversary of your actual start date. The remainder will vest ratably on a monthly basis over the next three years. The exercise
price of your stock options will be our closing stock price on your actual start date. Your award will also be subject to the terms of
our 2017 Employee, Director and Consultant Equity Incentive Plan and the Company’s form of award agreements.

5.              
Long Term Equity Incentive Award: You will also be eligible to receive an annual equity grant as part of the Company’s
next long term equity incentive award cycle, which we expect to commence in the first quarter of 2022. The Company will target a grant
date fair value of the annual equity awards of up to $900,000.00. The value of your award will be discretionary and will be subject to
your achievement of the metrics and goals established by the Company. Your equity grant will be subject to valuation methodologies and
other terms and conditions applicable to other similarly situated executives of the Company, and will be subject to Compensation Committee
approval.


 


6.                 
Relocation. This is a Boston-based position and you will be expected to work in the Company’s Boston area office unless
you are travelling on business. You agree to use your best efforts to establish a residence in the Boston area on or before September
15, 2021. The Company will reimburse your actual, reasonable transitional housing expenses through September 15, 2021.


 


7.              
At-Will Employment; Accrued Obligations: Your employment is “at will,” meaning you or the Company may terminate
your employment at any time for any or no reason. In the event of the termination of your employment for any reason, the Company shall
pay you the “Accrued Obligations,” defined as (1) your base salary through the date of termination; (2) an amount equal
to the value of your accrued unused vacation days; (3) the amount of any expenses properly incurred by you on behalf of the Company prior
to any such termination and not yet reimbursed; and (4) to the extent not theretofore paid or provided,
any other amounts or benefits required to be paid or provided or which you have earned under any plan or agreement of or with the Company
through the date of termination.


 


8.              
Severance: Without limiting the at-will nature of your employment relationship, if the Company terminates your employment
without Cause, or if you resign for Good Reason, the Company shall provide you with the following
termination benefits (the “Termination Benefits”): 


 


		(a)	Salary Continuation Payments. Continuation of your base salary
for a period of twelve (12) months after the date of termination (the “Severance Period”) at the salary
rate then in effect.



 






     


    	Michael Doyle
 Employment Agreement

		(b)	Target Bonus. An amount equal to your applicable annual target bonus for the year of termination,
paid in one lump sum on the Company’s next regularly-scheduled payroll date following the effective date of the separation agreement
described below.



 


		(c)	Acceleration of Sign-On Equity Award. Notwithstanding anything
to the contrary in the applicable equity plan or the award agreement applicable to your Sign-On Equity Award, any outstanding but unvested
portion of your Sign-On Equity Award that would have vested during the Severance Period had you remained employed during such time shall
accelerate and become fully-vested and exercisable as of the later of (A) the termination date, or (B) the effective date of the separation
agreement described below.



 


		(d)	Health Benefits Continuation. Continuation of group health plan benefits to the extent authorized
by and consistent with 29 U.S.C. § 1161 et seq. (commonly known as “COBRA”), with the cost of the regular premium for
such benefits shared in the same relative proportion by the Company and you as in effect on the date of termination until the earlier
of (i) the end of the Severance Period; or (ii) the date you become eligible for health benefits through another employer or otherwise
become ineligible for COBRA (“Health Benefits Continuation Payments”). Notwithstanding the above, (x) in the event
that the Severance Period extends beyond eighteen (18) months following your date of termination, or (y) if the Company otherwise determines
in its sole discretion that it cannot provide the foregoing Health Benefits Continuation Payments without potentially violating applicable
law (including but not limited to the 2010 Patient Protection and Affordable Care Act, as amended by the 2010 Health Care and Education
Reconciliation Act), the Company shall in lieu thereof provide to you a taxable monthly payment in an amount equal to the Company’s
portion of the monthly COBRA premium (as described above) that you would be required to pay to continue your group health coverage in
effect on the date of your termination (which amount shall be based on the premium for the first month of COBRA coverage), which payments
shall be made on the last day of each month regardless of whether COBRA continuation coverage remains available (i.e., in the event that
the Severance Period extends beyond eighteen (18) months following your date of termination) and shall end on the earlier of (1) the end
of the Severance Period, (2) the date you become eligible for health benefits through another employer or otherwise become ineligible
for COBRA; or (3) the last day of the twenty-fourth (24th) calendar month following your termination date.



 


If the Company terminates your employment without Cause,
or if you resign for Good Reason, and the effective date of such termination occurs within the 90 day period immediately preceding or
the twelve (12) month period immediately following a Change-in-Control (such period the “Change-in-Control Period”
and such termination a “Change-in-Control Termination”), then in addition to the Termination Benefits set forth immediately
above:


 






     


    	Michael Doyle

Equity Acceleration. Notwithstanding anything
to the contrary in any applicable equity plan or award agreement, all of your outstanding but unvested equity awards shall accelerate
and become fully-vested and exercisable as of the later of (A) the termination date, or (B) the effective date of the separation agreement
described below, or (C) as of the Change-in-Control.


 


Notwithstanding anything to the contrary in this Agreement,
you shall not be entitled to any Termination Benefits unless (a) within 60 days of your date of termination, you first (i) enter into,
do not revoke, and comply with the terms of a separation agreement in a form acceptable to the Company, which shall include a general
release in favor of the Company and related persons and entities, and other provisions regarding non-competition, confidentiality, cooperation,
non-disparagement and the like as may be included in the Company’s then current form of separation agreement (the “Release”);
(ii) resign from any and all positions, including, without implication of limitation, as a director, trustee, and officer, that you then
hold with the Company and any affiliate of the Company; and (iii) return all Company property and comply with any instructions related
to deleting and purging duplicates of such Company property, and (b) you comply with the terms of your Non-Competition, Non-Solicitation,
Confidentiality and Assignment Agreement or any other similar agreements with the Company. The Salary Continuation Payments shall commence
within 60 days after the date of termination and shall be made on the Company’s regular payroll dates; provided, however, that if
the 60-day period begins in one calendar year and ends in a second calendar year, the Salary Continuation Payments shall begin to be paid
in the second calendar year. In the event you miss a regular payroll period between the date of termination and the first Salary Continuation
Payment, the first Salary Continuation Payment shall include a “catch up” payment.


 


For purposes of this Section:


 


“Cause” means the occurrence of any
of the following (and, if applicable, that the Company has complied with the Cause Process (hereinafter defined) following the occurrence
of a circumstance subject to the Cause Process): (i) theft, fraud, embezzlement, misappropriation of assets or property of the Company,
or material violation of your Non-Competition, Non-Solicitation, Confidentiality and Assignment Agreement; (ii) dishonesty, gross negligence,
misconduct, neglect of duties, or breach of fiduciary duty to the Company; (iii) violation of federal or state securities laws; (iv) breach
of an employment, consulting or other agreement with the Company; (v) the conviction of a felony, or any crime involving moral turpitude,
including a plea of guilty or nolo contendere; or (vi) continued, willful and deliberate non-performance by you of your duties
hereunder (other than by reason of your physical or mental illness, incapacity or disability).


 






     


    	Michael Doyle
 Employment Agreement

“Cause Process” means that (1) the
Company has reasonably determined in good faith that a “Cause” condition has occurred; (2) the Company has notified you in
writing of the first occurrence of the Cause condition within 60 days of the first occurrence of such condition; (3) you are provided
a period of 30 days following such notice (the “Cause Cure Period”) to remedy the condition; (4) notwithstanding such
efforts, the Company reasonably and in good faith determines at the end of the Cause Cure Period that the Cause condition continues to
exist; and (5) the Company terminates your employment within 30 days after the end of the Cause Cure Period. If you cure the Cause condition
during the Cause Cure Period, Cause shall be deemed not to have occurred. The Company shall not be required to follow the Cause Process
as to those conditions which it reasonably determines in good faith cannot be cured within the Cause Cure Period. For the avoidance of
doubt, you and the Company acknowledge and agree that clauses (i), (iii) and (v) cannot be cured, and shall not be subject to the requirements
of the Cause Process.


 


“Change-in-Control” means the occurrence
of any of the following events: (i) 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 the Company representing fifty percent (50%) or more of the total voting power represented by the Company’s then
outstanding voting securities; (ii) a change in the composition of the Company’s Board of Directors occurring within a two-year
period, as a result of which fewer than a majority of the directors are Incumbent Directors. “Incumbent Directors” will mean
directors who either (A) are directors of the Company as of the date hereof, or (B) are elected, or nominated for election,
to the Board with the affirmative votes of at least a majority of the Incumbent Directors at the time of such election or nomination (but
will not include an individual whose election or nomination is in connection with an actual or threatened proxy contest relating to the
election of directors to the Company); (iii) the consummation of a merger or consolidation of the Company, other than a merger or consolidation
which would result in the voting securities of the 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 the Company or such surviving entity or parent of such corporation,
as the case may be, outstanding immediately after such merger or consolidation; or (iv) the consummation of the sale or disposition by
the Company of all or substantially all of the Company’s assets.

“Good Reason” means that you have
complied with the Good Reason Process following the occurrence of any of the following actions undertaken by the Company without your
express prior written consent: (i) the material diminution in your authority, duties and responsibilities; (ii) a material reduction in
your base salary, provided, however, that Good Reason shall not be deemed to have occurred in the event of a reduction in your base salary
that is pursuant to a salary reduction program affecting or a material portion of the similarly situated senior level employees of the
Company and that does not adversely affect you to a greater extent than such similarly situated employees; and (iii) a change in the geographic
location at which you must regularly report to work and perform services of more than thirty (30) miles, except for required travel on
the Company’s business; or (v) a material breach by the Company of any of its obligations to you under its employment agreements
with you.


 


“Good Reason Process” means that
(1) you have reasonably determined in good faith that a “Good Reason” condition has occurred; (2) you have notified the Company
in writing of the first occurrence of the Good Reason condition within 30 days of the first occurrence of such condition; (3) the Company
is provided with a period of 30 days following such notice (the “Cure Period”) to remedy the condition; (4) notwithstanding
such efforts, you reasonably and in good faith determine at the end of the Cure Period that the Good Reason condition continues to exist;
and (5) you terminate your employment within 30 days after the end of the Cure Period. If the Company cures the Good Reason condition
during the Cure Period, Good Reason shall be deemed not to have occurred.


 


9.                 
Section 280G:


 


		(a)	If any payment or benefit you would receive under this Agreement, when combined with any other payment or
benefit you receive pursuant to a Change-in-Control (for purposes of this Section, a “Payment”) would constitute a
 “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”)
and, but for this sentence, be subject to the excise tax imposed by Code Section 4999 (the “Excise Tax”), then such
Payment shall be either: (i) the full amount of such Payment; or (ii) such lesser amount (a “Reduced Payment”) 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 employment taxes, income taxes and the Excise Tax, results in your 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.



 


		(b)	With respect to Section 10(a), if there is more than one method of reducing the Reduced Payment amount that
would result in no portion of the Payment being subject to the Excise Tax, then the Payment shall be reduced or eliminated in the following
order: (i) cash payments; (ii) taxable benefits; (iii) nontaxable benefits; and (iv) accelerated vesting of equity awards in a manner
that maximizes the amount to be received by you.



 






     


    	Michael Doyle
 Employment Agreement

		(c)	The determination of whether Section 10(a)(i) or (ii) applies, and the calculation of the amount of the Reduced
Payment if applicable, shall be performed by a nationally recognized certified public accounting firm as may be designated by the Company
(the “Accounting Firm”). The Accounting Firm shall provide detailed supporting calculations to both the Company and
you within fifteen (15) business days of the receipt of notice from you that there has been a Payment, or such earlier time as is requested
by the Company, in a form that can be relied upon for tax filing purposes. All fees and expenses of the Accounting Firm shall be borne
solely by the Company.



 


		(d)	You may receive a Payment that is, in the aggregate, either more or less than the amount described in Section
10(a)(i) or (ii) (as applicable, an “Overpayment” or “Underpayment”). If it is finally determined
by a court of competent jurisdiction pursuant to a final non-appealable judgment, or the Internal Revenue Service, or by the Accounting
Firm upon request by either the Company or you, that an Overpayment or Underpayment has been made, then: (i) in the event of an Overpayment,
you shall promptly repay the Overpayment to the Company, together with interest on the Overpayment at the applicable federal rate from
the date of your receipt of such Overpayment until the date of such repayment; and (ii) in the event of an Underpayment, the Company shall
promptly pay an amount equal to the Underpayment to you, together with interest on such amount at the applicable federal rate from the
date such amount would have been paid to you had the provisions of Section 10(a)(ii) not been applied until the date of payment.



 


10.             
Section 409A: Anything in this Agreement to the contrary notwithstanding, if at the time of your separation from
service within the meaning of Section 409A of the Code, the Company determines that you are a “specified employee” within
the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that you become entitled to under this
Agreement on account of your separation from service would be considered deferred compensation subject to the 20 percent additional tax
imposed pursuant to Section 409A(a) of the Code, such payment shall not be payable and such benefit shall not be provided until the
date that is the earlier of (A) six months and one day after your separation from service, or (B) your death. If any such delayed
cash payment is otherwise payable on an installment basis, the first payment shall include a catch-up payment covering amounts that would
otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments shall
be payable in accordance with their original schedule. All in-kind benefits provided and expenses eligible for reimbursement under this
Agreement shall be provided by the Company or incurred by you during the time periods set forth in this Agreement. All reimbursements
shall be paid as soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable
year following the taxable year in which the expense was incurred. The amount of in-kind benefits provided or reimbursable expenses incurred
in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for reimbursement in any other taxable
year. Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit. To the extent that
any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under Section 409A
of the Code, and to the extent that such payment or benefit is payable upon your termination of employment, then such payments or benefits
shall be payable only upon your “separation from service.” The Company and you intend that this Agreement will be administered
in accordance with Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous as to its compliance with
Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with Section 409A of the
Code. It is intended that each installment of the severance payments and benefits provided under this Agreement shall be treated as a
separate “payment” for purposes of Section 409A. Neither the Company nor you 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. The Company makes no
representation or warranty and shall have no liability to you or any other person if any provisions of this Agreement are determined to
constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such
Section.

11.             
No Guarantee of Tax Consequences: The Company makes no guarantee of any tax consequences
with respect to any payment hereunder, including, without limitation, under Section 409A of the Code.


 


12.             
No Mitigation: In no event, except as set forth expressly in this or another agreement
signed by you, shall you be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to
you under any of the provisions of this Agreement and, subject to the aforesaid exception, such amounts shall not be reduced whether or
not you obtain other employment.


 


13.             
Return of Company Property: Upon termination of employment for any reason, you shall promptly
return to the Company any keys, credit cards, passes, confidential documents or material, computer equipment, or other property belonging
to the Company, and you shall also return all writings, files, records, correspondence, notebooks, notes and other documents and things
(including any copies thereof) containing confidential information or relating to the business or proposed business of the Company or
its affiliated entities or containing any trade secrets relating to the Company or its affiliated entities. For purposes of the preceding
sentence, the term “trade secrets” shall have the meaning ascribed to it under the Uniform Trade Secrets Act. You agree to
represent in writing to the Company upon termination of employment that you have complied with the foregoing provisions of this Section.


 


14.             
Assistance with Claims: You agree that, consistent with your business and personal affairs,
during and after your employment by the Company, you will assist the Company and its affiliated entities in the defense of any claims,
or potential claims that may be made or are threatened to be made against any of them in any action, suit or proceeding, whether civil,
criminal, administrative or investigative (a “Proceeding”), and will assist the Company and its affiliated entities
in the prosecution of any claims that may be made by the Company or its affiliated entities in any Proceeding, to the extent that such
claims may relate to your employment or the period of your employment by the Company. The Company agrees to reimburse you for your reasonable
out-of-pocket expenses associated with such assistance, including travel expenses. Any amounts to be paid to you pursuant to this Section 15
shall be paid by the Company within no later than thirty (30) days of the date on which you provide documentation to the Company
that such expenses were incurred.

time and attention to your work at the Company. If you have entered into any agreement that may restrict your activities on behalf of
the Company, please provide me with a copy of the agreement as soon as possible.

Non-Solicitation, Confidentiality and Assignment Agreement” as a condition of your employment. A copy of that Agreement is enclosed.

the Termination Benefits.

Other Terms: Your employment with the Company shall be on an at-will basis. In other words, you or the Company may
