Matthew Garrett 
 Dear Matt: 

We are pleased to offer you the position of Chief Financial Officer with iRhythm Technologies, Inc. (the “Company”). You shall
devote your best efforts and full business time, skill and attention to the performance of your duties. Notwithstanding the above, you shall be allowed to be an independent director of C-8 Medi-Sensors, a glucose monitoring company located in San
Jose, CA, subject to the Company’s reassessment six (6) months following your Start Date to ensure that such board service is not conflicting with your employment with the Company. Your service on other boards requires advance approval of
the Board and is restricted to non- competitive entities. You may engage in civic and not-for-profit activities as long as such activities do not interfere with the performance of your duties hereunder. If you decide to join us, you will receive a
salary and certain employee benefits as explained in Exhibit A. You should note that the Company may modify job titles, salaries, and benefits from time to time as it deems necessary. 

In addition, if you decide to join the Company, it will be recommended at the first meeting of the Company’s Board of Directors following
your start date that the Company grant you an option to purchase 400,000 shares of the Company’s Common Stock at a price per share equal to the fair market value per share of the Common Stock on the date of grant, as determined by the
Company’s Board of Directors. Twenty-five percent of the shares subject to the option shall vest 12 months after the date your vesting begins subject to your continuing employment with the Company, and no shares shall vest before such date. The
remaining shares shall vest monthly over the next 36 months in equal monthly amounts subject to your continuing employment with the Company. This option grant shall be subject to the terms and conditions of the Company’s Stock Option Plan and
Stock Option Agreement, including vesting requirements. No right to any stock is earned or accrued until such time that vesting occurs, nor does the grant confer any right to continue vesting or employment.

 We also ask that, if you have not already done so, you disclose to the
Company any and all agreements relating to your prior employment that may affect your eligibility to be employed by the Company or limit the manner in which you may be employed. It is the Company’s understanding that any such agreements will
not prevent you from performing the duties of your position and you represent that such is the case. Moreover, you agree that, during the term of your employment with the Company, you will not engage in any other employment, occupation, consulting
or other business activity directly related to the business in which the Company is now involved or becomes involved during the term of your employment, nor will you engage in any other activities that conflict with your obligations to the Company.
Similarly, you agree not to bring any third party confidential information to the Company, including that of your former employer, and that in performing your duties for the Company you will not in any way utilize any such information. 

As a Company employee, you will be expected to abide by the Company’s rules and standards. As a condition of your employment, you are
also required to sign and comply with an At Will Employment, Confidential Information, Invention Assignment, and Arbitration Agreement which requires, among other provisions, the assignment of patent rights to any invention made during your
employment at the Company, and nondisclosure of Company proprietary information. In the event of any dispute or claim relating to or arising out of our employment relationship, you and the Company agree that (i) any and all disputes between you

 Exhibit 10.29 

IRHYTHM TECHNOLOGIES, INC. 

CHANGE OF CONTROL AND SEVERANCE AGREEMENT 

This Change of Control and Severance Agreement (the “Agreement”) is made and entered into by and between [NAME]
(“Executive”) and iRhythm Technologies, Inc. (the “Company”, and collectively with the Executive, the “Parties”) as of the date the Company and Executive have each executed this Agreement, as set forth below. The terms
of this Agreement will become effective on the effective date of the first registration statement that is filed by the Company and declared effective pursuant to Section 12(g) of the Securities Exchange Act of 1934, as amended, with
respect to any class of the Company’s securities (the “Effective Date”). 
 RECITALS 

1.    The Parties previously entered into a certain employment offer letter dated [DATE] (as amended, the “Offer
Letter”) and a Change of Control Severance Agreement dated [DATE] (the “Prior Agreement”). 
 2.    The
Board of Directors of the Company (the “Board”) believes that it is in the best interests of the Company and its stockholders to provide Executive with severance benefits if Executive’s employment with the Company terminates for
certain reasons in the ordinary course of business, and to provide Executive with additional severance benefits if such termination occurs following a Change of Control. 

3.    These severance benefits will provide Executive with enhanced financial security and incentive and encouragement to
remain with the Company and to stay focused on the Company’s business. 
 4.    Certain capitalized terms used in
the Agreement are defined in Section [9/10] below. 
 AGREEMENT 

NOW, THEREFORE, in consideration of the mutual covenants contained herein, the Parties hereto agree as follows: 

5.    Term of Agreement. This Agreement will have a term of two (2) years following the Effective Date. If
Executive’s employment terminates for any reason during the term or if the Company experiences a Change of Control, including (without limitation) any termination not set forth in Section 6, Executive will not be entitled to any payments,
benefits, damages, awards or compensation other than as provided by this Agreement, notwithstanding any provision to the contrary in the Offer Letter or any other prior agreement entered into by the Parties (including, but not limited to, any Equity
Award agreements). Following the expiration of the two (2) year period without a written agreement by the Parties to renew or extend this Agreement, this Agreement will terminate and cease to be of any force or effect. Notwithstanding the
foregoing, in the event that the 

 
Company enters into an agreement or understanding regarding a Change of Control which limits its ability to extend this Agreement when there are fewer than twelve (12) months remaining in
the term, the term of the Agreement will be extended through the twelve (12) month anniversary of such Change of Control. 

6.    Severance Benefits. 

(a)    Termination Outside the Change of Control Period. If, outside the Change of Control Period, the Company or
its Affiliates terminate Executive’s employment with the Company or its Affiliates, respectively, other than for Cause, death or Disability, or Executive resigns from such employment for Good Reason, then, subject to Section 7, Executive
will receive the following severance benefits: 
 (i)    Salary Severance. Continuing payments of severance pay
at a rate equal to Executive’s annual base salary, at the highest rate in effect during the term of this Agreement, for [Tier 1: twelve (12) /Tier 2: nine (9) /Tier 3: six (6)] months from the date of Executive’s termination of
employment, which will be paid in accordance with the Company’s regular payroll procedures. 

(ii)    Continued Employee Benefits. If Executive elects continuation coverage pursuant to the Consolidated
Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) within the time period prescribed pursuant to COBRA for Executive and Executive’s eligible dependents, the Company will pay Executive’s group health insurance
provider the premiums necessary to continue group health insurance benefits for Executive and Executive’s eligible dependents (at the coverage levels in effect immediately prior to Executive’s termination) until the earlier of (A) a
period of [Tier 1: twelve (12) /Tier 2: nine (9) /Tier 3: six (6)] months from the date of Executive’s termination of employment, (B) the date upon which Executive and/or Executive’s eligible dependents becomes covered under
similar plans or (C) the date upon which Executive ceases to be eligible for coverage under COBRA (such payments, the “COBRA Premiums”). However, if the Company determines in its sole discretion that it cannot pay the COBRA Premiums
without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company will in lieu thereof provide to Executive a taxable monthly payment payable on the last day of a given
month (except as provided by the following sentence), in an amount equal to the monthly COBRA premium that Executive would be required to pay to continue Executive’s group health coverage in effect on the date of Executive’s termination of
employment (which amount will be based on the premium for the first month of COBRA coverage), which payments will be made regardless of whether Executive elects COBRA continuation coverage and will commence on the month following Executive’s
termination of employment and will end on the earlier of (x) the date upon which Executive obtains other employment or (y) the date the Company has paid an amount equal to [Tier 1: twelve (12) /Tier 2: nine (9) /Tier 3: six (6)]
payments. For the avoidance of doubt, the taxable payments in lieu of COBRA Premiums may be used for any purpose, including, but not limited to continuation coverage under COBRA, and will be subject to all applicable tax withholdings.
Notwithstanding anything to the contrary under this Agreement, if at any time the Company determines in its sole discretion that it cannot provide the payments contemplated by the preceding sentence without violating applicable law (including,
without limitation, Section 2716 of the Public Health Service Act), Executive will not receive such payment or any further reimbursements for COBRA premiums. 

  
 -2- 

 (iii)    [Tier 1: Extension of Exercise Period for Vested Stock
Options: Notwithstanding any other provision in any applicable equity compensation plan and/or individual stock option agreement, Executive’s outstanding and vested Original Options as of the Executive’s termination of employment date
will remain exercisable until the eighteen (18) month anniversary of the termination of employment date; provided, however, that the post-termination exercise period for either Original Option will not extend beyond the earlier of its original
maximum term or the tenth (10th) anniversary of the original date of grant.] 

(b)    Termination within the Change of Control Period. If, within the Change of Control Period, the Company or its
Affiliates terminate Executive’s employment with the Company or its Affiliates, respectively, other than for Cause, death or Disability or Executive resigns from such employment for Good Reason, then, subject to Section [8/9], Executive
will receive the following severance benefits from the Company: 
 (i)    Salary Severance. A lump sum severance
payment equal to [Tier 1: twenty-four (24) /Tier 2: fifteen (15) /Tier 3: nine (9)] months of Executive’s annual base salary, at the highest rate in effect during the term of this Agreement, which will be paid in accordance with the
Company’s regular payroll procedures. For the avoidance of doubt, if (A) Executive incurred a termination prior to a Change of Control that qualifies Executive for severance payments under Section 6(a)(i); and (y) a Change of
Control occurs within the three (3)-month period following Executive’s termination of employment that qualifies Executive for the superior benefits under this Section 6(b)(i), then Executive shall be entitled to a lump-sum payment of the
amount calculated under this Section 6(b)(i), less amounts already paid under Section 6(a)(i). 

(ii)    Continued Employee Benefits. If Executive elects continuation coverage pursuant to COBRA within the time
period prescribed pursuant to COBRA for Executive and Executive’s eligible dependents, the Company will pay Executive’s group health insurance provider the premiums necessary to continue group health insurance benefits for Executive and
Executive’s eligible dependents (at the coverage levels in effect immediately prior to Executive’s termination) until the earlier of (A) a period of [Tier 1: twenty-four (24) /Tier 2: fifteen (15) /Tier 3: nine (9)] months
from the date of Executive’s termination of employment, (B) the date upon which Executive and/or Executive’s eligible dependents becomes covered under similar plans or (C) the date upon which Executive ceases to be eligible for
coverage under COBRA (such payments, the “COC Premiums”). However, if the Company determines in its sole discretion that it cannot pay the COC Premiums without potentially violating applicable law (including, without limitation,
Section 2716 of the Public Health Service Act), the Company will in lieu thereof provide to Executive a taxable monthly payment payable on the last day of a given month (except as provided by the following sentence), in an amount equal to the
monthly COBRA premium that Executive would be required to pay to continue Executive’s group health coverage in effect on the date of Executive’s termination of employment (which amount will be based on the premium for the first month of
COBRA coverage), which payments will be made regardless of whether Executive elects COBRA continuation coverage and will commence on the month following Executive’s termination of employment and will end on the earlier of (x) the date upon
which Executive obtains other 

  
 -3- 

 
employment or (y) the date the Company has paid an amount equal to [Tier 1: twenty-four (24) /Tier 2: fifteen (15) /Tier 3: nine (9)] payments. For the avoidance of doubt, the
taxable payments in lieu of COBRA Premiums may be used for any purpose, including, but not limited to continuation coverage under COBRA, and will be subject to all applicable tax withholdings. Notwithstanding anything to the contrary under this
Agreement, if at any time the Company determines in its sole discretion that it cannot provide the payments contemplated by the preceding sentence without violating applicable law (including, without limitation, Section 2716 of the Public
Health Service Act), Executive will not receive such payment or any further reimbursements for COBRA premiums. 

(iii)    Equity. Executive will be entitled to accelerated vesting as one hundred percent (100%) of the then
unvested portion of all of Executive’s outstanding Equity Awards. If, however, an outstanding Equity Award is to vest and/or the amount of the Equity Award to vest is to be determined based on the achievement of performance criteria, then the
Equity Award will vest as to one hundred percent (100%) of the amount of the Equity Award assuming the performance criteria had been achieved at target levels for the relevant performance period(s). 

(iv)    [Tier 1: Extension of Exercise Period for Vested Stock Options: Notwithstanding any other provision in any
applicable equity compensation plan and/or individual stock option agreement, Executive’s outstanding and vested Original Options as of the Executive’s termination of employment date will remain exercisable until the eighteen
(18) month anniversary of the termination of employment date; provided, however, that the post-termination exercise period for either Original Option will not extend beyond the earlier of its original maximum term or the tenth (10th) anniversary of the original date of grant.] 

(c)    Voluntary Resignation; Termination for Cause. If Executive’s employment with the Company or its
Affiliates terminates (i) voluntarily by Executive (other than for Good Reason) or (ii) for Cause by the Company, then Executive will not be entitled to receive severance or other benefits except for those (if any) as may then be
established under the Company’s then existing severance and benefits plans and practices. 
 (d)    Disability;
Death. If the Company terminates Executive’s employment as a result of Executive’s Disability, or Executive’s employment terminates due to Executive’s death, then Executive will not be entitled to receive severance or other
benefits except for those (if any) as may then be established under the Company’s then existing written severance and benefits plans and practices. 

(e)    Accrued Compensation. For the avoidance of any doubt, in the event of a termination of Executive’s
employment with the Company or its Affiliates, Executive will be entitled to receive all accrued but unpaid vacation, expense reimbursements, wages, and other benefits due to Executive under any Company-provided plans, policies, and arrangements.

 (f)    Transfer between the Company and Affiliates. For purposes of this Section 2, if Executive’s
employment with the Company or one of its Affiliates terminates, Executive will not be determined to have been terminated other than for Cause, provided Executive continues to remain employed by the Company or one of its Affiliates (e.g., upon
transfer from on Affiliate to another); provided, however, that the parties understand and acknowledge that any such termination could potentially result in Executive’s ability to resign for Good Reason. 

  
 -4- 

 (g)    Exclusive Remedy. In the event of a termination of
Executive’s employment with the Company or its Affiliates, the provisions of this Section 6 are intended to be and are exclusive and in lieu of any other rights or remedies to which Executive or the Company may otherwise be entitled,
whether at law, tort or contract, in equity. Executive will be entitled to no benefits, compensation or other payments or rights upon termination of employment or in connection with a Change of Control other than those benefits expressly set forth
in this Section 6. 
 7.    Conditions to Receipt of Severance. 

(a)    Separation Agreement and Release of Claims. The receipt of any severance pursuant to Sections 6(a) or
(b) will be subject to Executive signing and not revoking a separation agreement and release of claims in a form reasonably satisfactory to the Company (the “Release”) and provided that such Release becomes effective and irrevocable
no later than sixty (60) days following the termination date (such deadline, the “Release Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, Executive will forfeit any rights to severance or
benefits under this Agreement. In no event will severance payments or benefits be paid or provided until the Release becomes effective and irrevocable. Except as required by Section 7(b), any severance payments or benefits under this Agreement
will be paid on, or, in the case of installments, will not commence until, a date within the ten (10) business day period following the date the Release becomes effective and irrevocable. Except as required by Section 7(b), any installment
payments that would have been made to Executive prior to the Release becoming effective and irrevocable but for the preceding sentence will be paid to Executive within ten (10) business days following the date the Release becomes effective and
irrevocable, and the remaining payments will be made as provided in the Agreement. 
 (b)    Section 409A.

 (i)    Notwithstanding anything to the contrary in this Agreement, no Deferred Payments will be paid or otherwise
provided until Executive has a “separation from service” within the meaning of Section 409A. Similarly, no severance payable to Executive, if any, pursuant to this Agreement that otherwise would be exempt from Section 409A
pursuant to Treasury Regulation Section 1.409A-1(b)(9) will be payable until Executive has a “separation from service” within the meaning of Section 409A. 

(ii)    Any severance payments or benefits under this Agreement that would be considered Deferred Payments will be paid
on, or, in the case of installments, will not commence until, the sixtieth (60th) day following Executive’s separation from service, or, if later, such time as required by Section 7(b)(iii). Except as required by
Section 7(b)(iii), any installment payments that constitute Deferred Payments that would have been made to Executive during the sixty (60) day period immediately following Executive’s separation from service but for the preceding
sentence will be paid to Executive on the sixtieth (60th) day following Executive’s separation from service and the remaining payments shall be made as provided in this Agreement. In no event will Executive have discretion to determine the
taxable year of payment for any Deferred Payments. 

  
 -5- 

 (iii)     Notwithstanding anything to the contrary in this Agreement, if
Executive is a “specified employee” within the meaning of Section 409A at the time of Executive’s separation from service (other than due to death), then the Deferred Payments that are payable within the first six (6) months
following Executive’s separation from service, will, to the extent required to be delayed pursuant to Section 409A(a)(2)(B) of the Code, become payable on the date six (6) months and one (1) day following the date of
Executive’s separation from service. All subsequent Deferred Payments, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if Executive dies
following Executive’s separation from service, but prior to the six (6) month anniversary of the separation from service, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively
practicable after the date of Executive’s death and all other Deferred Payments will be payable in accordance with the payment schedule applicable to each payment or benefit. Each payment and benefit payable under this Agreement is intended to
constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. 
 (iv)    Any
amount paid under this Agreement that satisfies the requirements of the “short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the Treasury Regulations will not constitute Deferred Payments. 

(v)    Any amount paid under this Agreement that qualifies as a payment made as a result of an involuntary separation
from service pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit (as defined below) will not constitute Deferred Payments. 

(vi)    The foregoing provisions and all compensation and benefits provided for under this Agreement are intended to
comply with or be exempt from the requirements of Section 409A so that none of the severance payments and benefits to be provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities or ambiguous
terms herein will be interpreted to be exempt or so comply. The Company and Executive agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or desirable to
avoid imposition of any additional tax or income recognition prior to actual payment to Executive under Section 409A. In no event will the Company reimburse Executive for any taxes that may be imposed on Executive as a result of
Section 409A. 
 8.    Tier 1: Treatment of Original Options in the Event of a Change of Control. In the
event of a Change of Control where the Aggregate Amount is equal to or greater than $400,000,000, and provided Executive remains an employee of the Company or an Affiliate through the date of such Change of Control, Executive’s Original
Options, to the extent unvested and outstanding on the date of such Change of Control, will accelerate and vest as to twenty-five percent (25%) of the total number of shares subject to the Original Options (provided that if fewer than
twenty-five percent (25%) of the total number of shares subject to the Original Options remain unvested and outstanding, all such remaining unvested shares will vest). For the avoidance of any doubt, the remaining shares subject to the Original
Options will continue to vest in accordance with the terms and conditions of the Original Options as if the shares that vested in connection with the Change of Control came from the shares subject to the Original Options that would have vested at
the end of each Original Option’s vesting schedule. For the further avoidance of any doubt, if any stock options held by 

  
 -6- 

 
Executive, including the Original Options, are not assumed or substituted for in connection with a Change of Control, 100% of the shares subject to such stock options, to the extent outstanding
and unvested, will fully vest and become exercisable pursuant to the terms and conditions of the 2006 Stock Plan, as amended.] 

9.    Limitation on Payments. In the event that the severance and other benefits provided for in this Agreement or
otherwise payable to Executive (i) constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and (ii) but for this Section [8/9], would be
subject to the excise tax imposed by Section 4999 of the Code, then Executive’s severance benefits under Section 6 will be either: 

(a)    delivered in full, or 

(b)    delivered as to such lesser extent which would result in no portion of such severance benefits being subject to
excise tax under Section 4999 of the Code, 
 whichever of the foregoing amounts, taking into account the applicable federal, state and local income
taxes and the excise tax imposed by Section 4999 of the Code, results in the receipt by Executive on an after-tax basis, of the greatest amount of severance benefits, notwithstanding that all or some portion of such severance benefits may be
taxable under Section 4999 of the Code. If a reduction in severance and other benefits constituting “parachute payments” is necessary so that benefits are delivered to a lesser extent, reduction will occur in the following order:
(i) reduction of cash payments; (ii) cancellation of awards granted “contingent on a change in ownership or control” (within the meaning of Code Section 280G); (iii) cancellation of accelerated vesting of Equity Awards;
or (iv) reduction of employee benefits. In the event that acceleration of vesting of Equity Award compensation is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant of the Equity Awards. 

Unless the Company and Executive otherwise agree in writing, any determination required under this Section 4 will be made in writing by a nationally
recognized certified professional services firm selected by the Company, the Company’s legal counsel or such other person or entity to which the parties mutually agree (the “Firm”) immediately prior to Change of Control, whose
determination will be conclusive and binding upon Executive and the Company for all purposes. For purposes of making the calculations required by this Section, the Firm may make reasonable assumptions and approximations concerning applicable taxes
and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and Executive will furnish to the Firm such information and documents as the Accountants may reasonably request
in order to make a determination under this Section. The Company will bear all costs the Firm may reasonably incur in connection with any calculations contemplated by this Section. 

10.    Definition of Terms. The following terms referred to in this Agreement will have the following meanings:

  
 -7-

which occurs on the date that any one person, or more than one person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than fifty percent
(50%) of the total voting power of the stock of the Company; provided, however, that for purposes of this subsection, the acquisition of additional stock by any one Person, who is considered to own more than fifty percent (50%) of the

final Treasury Regulations and Internal Revenue Service guidance that has been promulgated or may be promulgated thereunder from time to time. 

Further and for the avoidance of doubt, a transaction will not constitute a Change of Control if: (i) its sole purpose is to change the

(f)    Deferred Payment. “Deferred Payment” means any severance pay or benefits to be paid or provided
to Executive (or Executive’s estate or beneficiaries) pursuant to this Agreement and any other severance payments or separation benefits, that in each case, when considered together, are considered deferred compensation under Section 409A.

Executive’s Company duties as the result of Executive’s incapacity due to physical or mental illness, and such inability, at least twenty-six (26) weeks after its commencement or 180 days in any consecutive twelve (12) month
period, is determined to be total and permanent by a physician selected by the Company or its insurers and acceptable to Executive or Executive’s legal 

  
 -9- 

 
representative (such agreement as to acceptability not to be unreasonably withheld). Termination resulting from Disability may only be effected after at least thirty (30) days’ written
notice by the Company of its intention to terminate the Executive’s employment. In the event that the Executive resumes the performance of substantially all of Executive’s duties hereunder before the termination of Executive’s
employment becomes effective, the notice of intent to terminate will automatically be deemed to have been revoked. 

(h)    Equity Awards. “Equity Awards” means Executive’s outstanding stock options, stock
appreciation rights, restricted stock, restricted stock units, performance shares, performance stock units and any other Company equity compensation awards. 

(i)    Good Reason. “Good Reason” means Executive’s resignation within thirty (30) days
following the expiration of any Company cure period (discussed below) following the occurrence of one or more of the following, without Executive’s express written consent: (i) a material reduction by the Company of Executive’s base
salary in effect immediately prior to such reduction; (ii) a material reduction of Executive’s duties or responsibilities relative to Executive’s duties or responsibilities in effect immediately prior to such reduction; or
(iii) Executive’s relocation at the Company’s direction to a facility or location more than fifty (50) miles from Executive’s then present location of providing services. Executive’s resignation will not be deemed to be
for Good Reason unless Executive has first provided the Company with written notice of the acts or omissions constituting the grounds for “Good Reason” within ninety (90) days of the initial existence of the grounds for “Good
Reason” and a reasonable cure period of not less than thirty (30) days following the date the Company receives such notice, and such condition has not been cured during such period. 

(j)    [Tier 1: Original Options. “Original Options” means the initial stock option granted to
Executive on September 27, 2012 to purchase a number of shares of common stock of the Company equal to five percent (5%) of the shares of the Company, and the supplemental stock option granted to Executive on June 13, 2013 to purchase
a number of shares of common stock of the Company equal to the sum of (i) five percent (5%) of the shares of the Company on a fully diluted basis less (ii) the shares subject to the initial stock option, each as set forth in
the Offer Letter.] 
 (k)    Section 409A. For purposes of this Agreement, “Section 409A” means
Section 409A of the Code and any final regulations and guidance thereunder and any applicable state law equivalent, as each may be amended or promulgated from time to time. 

(l)    Section 409A Limit. For purposes of this Agreement, “Section 409A Limit” will mean two
(2) times the lesser of: (i) Executive’s annualized compensation based upon the annual rate of pay paid to Executive during the Executive’s taxable year preceding the Executive’s taxable year of Executive’s separation
from service as determined under Treasury Regulation Section 1.409A-1(b)(9)(iii)(A)(1) and any Internal Revenue Service guidance issued with respect thereto; or (ii) the maximum amount that may be taken into account under a qualified plan

(a)    The Company’s Successors. Any successor to the Company (whether direct or indirect and whether by
purchase, merger, consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets will assume the obligations under this Agreement and agree expressly to perform the obligations under this Agreement
in the same manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession. For all purposes under this Agreement, the term “Company” will include any successor to the
Company’s business and/or assets which executes and delivers the assumption agreement described in this Section or which becomes bound by the terms of this Agreement by operation of law. 

(b)    Executive’s Successors. The terms of this Agreement and all rights of Executive hereunder will inure to

communicated by a notice of termination to the other party hereto given in accordance with [Section 11/12(a)] of this Agreement. Such notice will indicate the specific termination provision in this Agreement relied upon, will set forth in
reasonable detail the facts and circumstances claimed to provide a basis for termination under the provision so indicated, and will specify the termination date (which will be not more than thirty (30) days after the giving of such notice). The
failure by Executive to include in the notice any fact or circumstance which contributes to a showing of Good Reason will not waive any right of Executive hereunder or preclude Executive from asserting such fact or circumstance in enforcing
Executive’s rights hereunder. 
 13.    Resignation. Upon the termination of Executive’s employment for
any reason, Executive will be deemed to have resigned from all officer and/or director positions held at the Company and its Affiliates voluntarily, without any further required action by Executive, as of the end of Executive’s employment and
Executive, at the Board’s request, will execute any documents reasonably necessary to reflect Executive’s resignation.

waiver or discharge is agreed to in writing and signed by Executive and by an authorized officer of the Company (other than Executive). No waiver by either party of any breach of, or of compliance with, any condition or provision of this Agreement

hereof, including, but not limited to, the Prior Agreement and terms within the Offer Letter that provide for payments or benefits in connection with a termination of employment and/or an event that constitutes a Change of Control. No waiver,
alteration, or modification of any of the provisions of this Agreement will be binding unless in writing and signed by duly authorized representatives of the parties hereto and which specifically mention this Agreement.
