 Exhibit 10.10 

RA MEDICAL SYSTEMS, INC. 

CHANGE IN CONTROL AND SEVERANCE AGREEMENT 

This Change in Control and Severance Agreement (the “Agreement”) is made between Ra Medical Systems, Inc. (the
“Company”) and Jeffrey Kraws (the “Executive”), effective as of the closing of an initial public offering of the Company’s securities pursuant to a registration statement on Form
S-1 that is declared effective with the U.S. Securities and Exchange Commission (the “Effective Date”). 

This Agreement provides certain protections to the Executive in connection with a change in control of the Company or in connection with the
involuntary termination of the Executive’s employment under the circumstances described in this Agreement. 
 The Company and the
Executive agree as follows: 
 1. Term of Agreement. This Agreement will have an initial term of three (3) years commencing on
the Effective Date (the “Initial Term”). On the third (3rd) anniversary of the Effective Date, this Agreement will renew automatically for additional, one (1) year terms
(each, an “Additional Term”) unless either party provides the other party with written notice of nonrenewal at least one (1) year prior to the date of automatic renewal. Notwithstanding the foregoing, if a Change in Control
occurs (a) when there are fewer than twelve (12) months remaining during the Initial Term or (b) during an Additional Term, the term of this Agreement will extend automatically through the date that is twelve (12) months
following the date of the Change in Control. If the Executive becomes entitled to the benefits under Section 3 of this Agreement, then the Agreement will not terminate until all of the obligations of the parties hereto with respect to this
Agreement have been satisfied. 
 2. At-Will Employment. The Company and the Executive
acknowledge that the Executive’s employment is and will continue to be at-will, as defined under applicable law. 

3. Severance Benefits. 

(a) Qualifying Non-CIC Termination. On a Qualifying
Non-CIC Termination (as defined below), the Executive will be eligible to receive the following payments and benefits from the Company: 

(i) Salary Severance. A single, lump sum payment equal to twelve (12) months of the Executive’s Salary (as defined below),
less applicable withholdings. 
 (ii) COBRA Coverage. Subject to Section 3(d), the Company will pay the premiums for coverage
under COBRA (as defined below) for the Executive and the Executive’s eligible dependents, if any, at the rates then in effect, subject to any subsequent changes in rates that are generally applicable to the Company’s active employees (the
“COBRA Coverage”), until the earliest of (A) a period of twelve (12) months from the date of the Executive’s termination of employment, (B) the date upon which the Executive (and the Executive’s
eligible dependents, as applicable) becomes covered under similar plans, or (C) the date upon which the Executive ceases to 







 
be eligible for coverage under COBRA. 
 (b) Qualifying CIC Termination. On a
Qualifying CIC Termination, the Executive will be eligible to receive the following payments and benefits from the Company: 
 (i) Salary
Severance. A single, lump sum payment equal to twelve (12) months of the Executive’s Salary, less applicable withholdings. 

(ii) Bonus Severance. A single, lump sum payment equal to 100% of the Executive’s target annual bonus as in effect for the fiscal
year in which the Qualifying CIC Termination occurs, less applicable withholdings. 
 (iii) COBRA Coverage. Subject to
Section 3(d), the Company will provide COBRA Coverage until the earliest of (A) a period of twelve (12) months from the date of the Executive’s termination of employment, (B) the date upon which the Executive (and the
Executive’s eligible dependents, as applicable) becomes covered under similar plans, or (C) the date upon which the Executive ceases to be eligible for coverage under COBRA. 

(iv) Equity Vesting Acceleration. Vesting acceleration (and exercisability, as applicable) as to 100% of the then-unvested shares
subject to each of the Executive’s then-outstanding Company equity awards. In the case of an equity award with performance-based vesting, unless otherwise specified in the applicable equity award agreement governing such award, all performance
goals and other vesting criteria will be deemed achieved at target. For the avoidance of doubt, in the event of the Executive’s Qualifying Pre-CIC Termination (as defined below), any unvested portion of
the Executive’s then-outstanding equity awards will remain outstanding until the earlier of (x) sixty (60) days following the Qualifying Termination or (y) the occurrence of a Change in Control, solely so that any benefits due on
a Qualifying Pre-CIC Termination can be provided if a Change in Control occurs within sixty (60) days following the Qualifying Termination (provided that in no event will the Executive’s stock
options or similar equity awards remain outstanding beyond the equity award’s maximum term to expiration). If no Change in Control occurs within sixty (60) days following a Qualifying Termination, any unvested portion of the
Executive’s equity awards automatically and permanently will be forfeited on the sixtieth (60th) day following the date of the Qualifying Termination without having vested. 

(c) Termination Other Than a Qualifying Termination. If the termination of the Executive’s employment with the Company Group is
not a Qualifying Termination, then the Executive will not be entitled to receive severance or other benefits. 
 (d) Conditions to
Receipt of COBRA Coverage. The Executive’s receipt of COBRA Coverage is subject to the Executive electing COBRA continuation coverage within the time period prescribed pursuant to COBRA for the Executive and the Executive’s eligible
dependents, if any. If the Company determines in its sole discretion that it cannot provide the COBRA Coverage without potentially violating, or being subject to an excise tax under, applicable law (including, without limitation, Section 2716
of the Public Health Service Act), then in lieu of any COBRA Coverage, the Company will provide to the Executive a taxable monthly payment payable on the last day of a given month (except as provided by the immediately following sentence), in an
amount equal 

  
 - 2 - 








 
to the monthly COBRA premium that the Executive would be required to pay to continue his or her group health coverage in effect on the date of his or her Qualifying Termination (which amount will
be based on the premium rates applicable for the first month of COBRA Coverage for the Executive and any of eligible dependents of the Executive) (each, a “COBRA Replacement Payment”), which COBRA Replacement Payments will be made
regardless of whether the Executive elects COBRA continuation coverage and will end on the earlier of (x) the date upon which the Executive obtains other employment or (y) the date the Company has paid an amount totaling the number of
COBRA Replacement Payments equal to the number of months in the applicable COBRA Coverage period. For the avoidance of doubt, the COBRA Replacement Payments may be used for any purpose, including, but not limited to continuation coverage under
COBRA, and will be subject to any applicable withholdings. Notwithstanding anything to the contrary under this Agreement, if the Company determines in its sole discretion at any time that it cannot provide the COBRA Replacement Payments without
violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Executive will not receive the COBRA Replacement Payments or any further COBRA Coverage. 

(e) Non-Duplication of Payment or Benefits. For purposes of clarity, in the event of a Qualifying Pre-CIC Termination, any severance payments and benefits to be provided to the Executive under Section 3(b) will be reduced by any amounts that already were provided to the Executive under
Section 3(a). Notwithstanding any provision of this Agreement to the contrary, if the Executive is entitled to any cash severance, continued health coverage benefits, or vesting acceleration of any equity awards (other than under this
Agreement) by operation of applicable law or under a plan, policy, contract, or arrangement sponsored by or to which any member of the Company Group is a party (“Other Benefits”), then the corresponding severance payments and
benefits under this Agreement will be reduced by the amount of Other Benefits paid or provided to the Executive. 
 (f) Death of the
Executive. In the event of the Executive’s death before all payments or benefits the Executive is entitled to receive under this Agreement have been provided, the unpaid amounts will be provided to the Executive’s designated
beneficiary, if living, or otherwise to the Executive’s personal representative in a single lump sum as soon as possible following the Executive’s death. 

(g) Transfer Between Members of the Company Group. For purposes of this Agreement, if the Executive is involuntarily transferred from
one member of the Company Group to another, the transfer will not be a termination without Cause but may give the Executive the ability to resign for Good Reason. 

(h) Exclusive Remedy. In the event of a termination of the Executive’s employment with the Company Group, the provisions of this
Agreement are intended to be and are exclusive and in lieu of any other rights or remedies to which the Executive may otherwise be entitled, whether at law, tort or contract, or in equity. The Executive will be entitled to no benefits, compensation
or other payments or rights upon termination of employment other than those benefits expressly set forth in this Agreement. 
 4. Accrued
Compensation. On any termination of the Executive’s employment with the Company Group, the Executive will be entitled to receive all accrued but unpaid vacation, expense 

  
 - 3 - 








 
reimbursements, wages, and other benefits due to the Executive under any Company-provided plans, policies, and arrangements. 

5. Conditions to Receipt of Severance. 

(a) Separation Agreement and Release of Claims. The Executive’s receipt of any severance payments or benefits upon the
Executive’s Qualifying Termination under Section 3 is subject to the Executive signing and not revoking the Company’s then-standard separation agreement and release of claims (which may include an agreement not to disparage any member
of the Company Group, non-solicit provisions, an agreement to assist in any litigation matters, and other standard terms and conditions) (the “Release” and that requirement, the
“Release Requirement”), which must become effective and irrevocable no later than the 60th day following the Executive’s Qualifying Termination (the “Release Deadline”). If the Release does not become effective
and irrevocable by the Release Deadline, the Executive will forfeit any right to severance payments or benefits under Section 3. 
 (b)
Payment Timing. Any lump sum Salary or bonus payments under Sections 3(a)(i), 3(b)(i), and 3(b)(ii) will be provided on the first regularly scheduled payroll date of the Company following the date the Release becomes effective and
irrevocable (the “Severance Start Date”), subject to any delay required by Section 5(d) below. Any taxable installments of any COBRA-related severance benefits that otherwise would have been made to the Executive on or before
the Severance Start Date will be paid on the Severance Start Date, and any remaining installments thereafter will be provided as specified in the Agreement. Any restricted stock units, performance shares, performance units, and/or similar full value
awards that accelerate vesting under Section 3(b)(iv) will be settled (x) on a date no later than ten (10) days following the date the Release becomes effective and irrevocable, or (y) if later, in the event of a Qualifying Pre-CIC Termination, on a date no later than the Change in Control. 
 (c) Return of Company
Property. The Executive’s receipt of any severance payments or benefits upon the Executive’s Qualifying Termination under Section 3 is subject to the Executive returning all documents and other property provided to the Executive
by any member of the Company Group (with the exception of a copy of the Company employee handbook and personnel documents specifically relating to the Executive), developed or obtained by the Executive in connection with his or her employment with
the Company Group, or otherwise belonging to the Company Group. 
 (d) Section 409A. The Company intends that all payments and
benefits provided under this Agreement or otherwise are exempt from, or comply with, the requirements of Section 409A of the Code and any guidance promulgated under Section 409A of the Code (collectively,
“Section 409A”) so that none of the payments or benefits will be subject to the additional tax imposed under Section 409A, and any ambiguities in this Agreement will be interpreted in accordance with this
intent. No payment or benefits to be paid to the Executive, if any, under this Agreement or otherwise, when considered together with any other severance payments or separation benefits that are considered deferred compensation under
Section 409A (together, the “Deferred Payments”) will be paid or otherwise provided until the Executive has a “separation from service” within the meaning of Section 409A. If, at the time of the Executive’s
termination of employment, the Executive is a “specified 

  
 - 4 - 








 
employee” within the meaning of Section 409A, then the payment of the Deferred Payments will be delayed to the extent necessary to avoid the imposition of the additional tax imposed
under Section 409A, which generally means that the Executive will receive payment on the first payroll date that occurs on or after the date that is 6 months and 1 day following the Executive’s termination of employment. The Company
reserves the right to amend this Agreement as it considers necessary or advisable, in its sole discretion and without the consent of the Executive or any other individual, to comply with any provision required to avoid the imposition of the
additional tax imposed under Section 409A or to otherwise avoid income recognition under Section 409A prior to the actual payment of any benefits or imposition of any additional tax. Each payment, installment, and benefit payable under
this Agreement is intended to constitute a separate payment for purposes of U.S. Treasury Regulation Section 1.409A-2(b)(2). In no event will any member of the Company Group reimburse, indemnify, or hold
harmless the Executive for any taxes, penalties and interest that may be imposed, or other costs that may be incurred, as a result of Section 409A. 

(e) Resignation of Officer and Director Positions. The Executive’s receipt of any severance payments or benefits upon the
Executive’s Qualifying Termination under Section 3 is subject to the Executive resigning from all officer and director positions with all members of the Company Group and the Executive executing any documents the Company may require in
connection with the same. 
 6. Limitation on Payments. 

(a) Reduction of Severance Benefits. If any payment or benefit that the Executive would receive from any Company Group member or
any other party whether in connection with the provisions in this Agreement or otherwise (the “Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of 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 the Payment will be equal to the Best Results Amount. The “Best Results Amount” will be either
(x) the full amount of the Payment or (y) a lesser amount that would result in no portion of the Payment being subject to the Excise Tax, whichever of those amounts, taking into account the applicable federal, state and local employment
taxes, income taxes and the Excise Tax, results in the Executive’s receipt, on an after-tax basis, of the greater amount. If a reduction in payments or benefits constituting parachute payments is
necessary so that the Payment equals the Best Results Amount, reduction will occur in the following order: (A) reduction of cash payments in reverse chronological order (that is, the cash payment owed on the latest date following the occurrence
of the event triggering the Excise Tax will be the first cash payment to be reduced); (B) cancellation of equity awards that were granted “contingent on a change in ownership or control” within the meaning of Section 280G of the
Code in the reverse order of date of grant of the awards (that is, the most recently granted equity awards will be cancelled first); (C) reduction of the accelerated vesting of equity awards in the reverse order of date of grant of the awards
(that is, the vesting of the most recently granted equity awards will be cancelled first); and (D) reduction of employee benefits in reverse chronological order (that is, the benefit owed on the latest date following the occurrence of the event
triggering the Excise Tax will be the first benefit to be reduced). In no event will the Executive have any discretion with respect to the ordering of Payment reductions. The Executive will be solely responsible for the payment of all personal tax
liability that is incurred as a result of the payments and benefits received under this Agreement, and the Executive will 

  
 - 5 - 








 
not be reimbursed, indemnified, or held harmless by any member of the Company Group for any of those payments of personal tax liability. 

(b) Determination of Excise Tax Liability. Unless the Company and the Executive otherwise agree in writing, the Company will
select a professional services firm (the “Firm”) to make all determinations required under this Section 6, which determinations will be conclusive and binding upon the Executive and the Company for all purposes. For purposes of
making the calculations required by this Section 6, 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 the Executive will furnish to the Firm such information and documents as the Firm reasonably may request in order to make determinations under this Section 6. The Company will bear the costs and make all
payments for the Firm’s services in connection with any calculations contemplated by this Section 6. The Company will have no liability to the Executive for the determinations of the Firm. 

7. Definitions. The following terms referred to in this Agreement will have the following meanings: 

(a) “Board” means the Company’s Board of Directors. 

(b) “Cause” means the occurrence of any of the following: (i) any willful, material violation by the Executive of any
law or regulation applicable to the business of any Company Group member, the Executive’s conviction for, or plea of guilty or no contest to, a felony or a crime involving moral turpitude, or any willful perpetration by the Executive of a
common law fraud, (ii) the Executive’s commission of an act of personal dishonesty which involves personal profit in connection with any Company Group member or any other entity having a business relationship with any Company Group member;
(iii) any material breach by the Executive of any provision of any agreement or understanding between any Company Group member and the Executive regarding the terms of the Executive’s service as an employee, officer, director or consultant
to any Company Group member, including without limitation, the willful and continued failure or refusal of the Executive to perform the material duties required of the Executive as an employee, officer, director or consultant of any Company Group
member, other than as a result of having a Disability, or a breach of any applicable invention assignment and confidentiality agreement or similar agreement between any Company Group member and the Executive, (iv) the Executive’s disregard
of the policies of any Company Group member so as to cause loss, damage or injury to the property, reputation or employees of any Company Group member, or (v) any other misconduct by the Executive which is materially injurious to the financial
condition or business reputation of, or is otherwise materially injurious to, any Company Group member. 
 (c) “Change in
Control” means the occurrence of any of the following events: 
 (i) A change in the ownership of the Company 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 50% of the total voting power of the
stock of the Company; provided, however, that for purposes of this subsection, (A) the acquisition of additional stock by any one Person, who is considered to own more 

  
 - 6 - 








 
than 50% of the total voting power of the stock of the Company will not be considered a Change in Control, and (B) if the stockholders of the Company immediately before such change in
ownership continue to retain immediately after the change in ownership, in substantially the same proportions as their ownership of shares of the Company’s voting stock immediately prior to the change in ownership, the direct or indirect
beneficial ownership of 50% or more of the total voting power of the stock of the Company or of the ultimate parent entity of the Company, such event will not be considered a Change in Control under this subsection (i). For this purpose, indirect
beneficial ownership will include, without limitation, an interest resulting from ownership of the voting securities of one or more corporations or other business entities which own the Company, as the case may be, either directly or through one or
more subsidiary corporations or other business entities; or 
 (ii) A change in the effective control of the Company which occurs on the
date that a majority of members of the Board is replaced during any 12 month period by members of the Board whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For
purposes of this subsection (ii), if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control; or 

(iii) A change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any Person acquires (or
has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross fair market value equal to or more than 50%
of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions; provided, however, that for purposes of this subsection (iii), the following will not constitute a change in the
ownership of a substantial portion of the Company’s assets: (A) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or (B) a transfer of assets by the Company to: (1) a
stockholder of the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s stock, (2) an entity, 50% or more of the total value or voting power of which is owned, directly or indirectly, by the
Company, (3) a Person, that owns, directly or indirectly, 50% or more of the total value or voting power of all the outstanding stock of the Company, or (4) an entity, at least 50% of the total value or voting power of which is owned,
directly or indirectly, by a Person described in this subsection (iii)(B)(3). For purposes of this subsection (iii), gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of, determined
without regard to any liabilities associated with such assets. 
 For purposes of this definition, persons will be considered to be acting
as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company. 

Notwithstanding the foregoing, a transaction will not be deemed a Change in Control unless the transaction qualifies as a change in control
event within the meaning of Section 409A. 
 Further and for the avoidance of doubt, a transaction will not constitute a Change in
Control if: (i) its sole purpose is to change the state of the Company’s incorporation, or (ii) 

  
 - 7 - 








 
its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction.

 (d) “Change in Control Period” means the period beginning three (3) months prior to a Change in Control and ending
twelve (12) months following a Change in Control. 
 (e) “COBRA” means the Consolidated Omnibus Budget Reconciliation

(g) “Company Group” means the Company and its subsidiaries. 

(h) “Confidentiality Agreement” means the At-Will Employment, Confidential
Information, Invention Assignment, Nonsolicitation, and Arbitration Agreement. 
 (i) “Disability” means a total and
permanent disability as defined in Section 22(e)(3) of the Code. 
 (j) “Good Reason” means the termination of the Executive’s employment with the Company Group by the Executive in accordance with the next sentence after the occurrence of one or more of the following events
without the Executive’s express written consent: (i) a material reduction of the Executive’s duties, authorities, or responsibilities relative to the Executive’s duties, authorities, or responsibilities in effect immediately
prior to the reduction; provided, however, that continued employment following a Change in Control with substantially the same duties, authorities, or responsibilities with respect to the Company Group’s business and operations will not
constitute “Good Reason” (for example, “Good Reason” does not exist if the Executive is employed by the Company Group or a successor with substantially the same duties, authorities, or responsibilities with respect to the Company
Group’s business that the Executive had immediately prior to the Change in Control regardless of whether the Executive’s title is revised to reflect the Executive’s placement within the overall corporate hierarchy or whether the
Executive provides services to a subsidiary, affiliate, business unit or otherwise); (ii) a reduction by a Company Group member in the Executive’s rate of annual base salary by more than 10%; provided, however, that, a reduction of annual base
salary that also applies to substantially all other similarly situated employees of the Company Group members will not constitute “Good Reason”; (iii) a material change in the geographic location of the Executive’s primary work
facility or location by more than 35 miles from the Executive’s then present location; provided, that a relocation to a location that is within 35 miles from the Executive’s then-present primary residence will not be considered a material
change in geographic location, or (iv) failure of a successor corporation to assume the obligations under this Agreement as contemplated by Section 8. In order for the termination of the Executive’s employment with a Company Group
member to be for Good Reason, the Executive must not terminate employment without first providing written notice to the Company of the acts or omissions constituting the grounds for “Good Reason” within 60 days of the initial existence of
the grounds for “Good Reason” and a cure period of 30 days following the date of written notice (the “Cure Period”), the grounds must not have been cured during that time, and the Executive must terminate the
Executive’s employment within 30 days following the Cure Period.

Termination” means a Qualifying CIC Termination that occurs prior to the date of the Change in Control. 
 (l) “Qualifying
Termination” means a termination of the Executive’s employment either (i) by a Company Group member without Cause (excluding by reason of Executive’s death or Disability) or (ii) by the Executive for Good Reason, in
either case, during the Change in Control Period (a “Qualifying CIC Termination”) or outside of the Change in Control Period (a “Qualifying Non-CIC Termination”). 

(m) “Salary” means the Executive’s annual base salary as in effect immediately prior to the Executive’s Qualifying
Termination (or if the termination is due to a resignation for Good Reason based on a material reduction in base salary, then the Executive’s annual base salary in effect immediately prior to the reduction) or, if the Executive’s
Qualifying Termination is a Qualifying CIC Termination and the amount is greater, at the level in effect immediately prior to the Change in Control. 

8. Successors. This Agreement will be binding upon and inure to the benefit of (a) the heirs, executors, and legal representatives

of the rights of the Executive to receive any form of compensation payable pursuant to this Agreement may be assigned or transferred except by will or the laws of descent and distribution. Any other attempted assignment, transfer, conveyance, or
other disposition of the Executive’s right to compensation or other benefits will be null and void.

(v) 3 business days after deposit with the U.S. Postal Service by first class certified or registered mail, return receipt requested, postage prepaid, addressed (A) if to the Executive, at the address the Executive shall have most recently

reflect the resignations.

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

(c) Headings. All captions and section headings used in this Agreement are for convenient reference only and do not form a part of this
Agreement. 
 (d) Entire Agreement. This Agreement constitutes the entire agreement of the parties and supersedes in their entirety
all prior representations, understandings, undertakings or agreements (whether oral or written and whether expressed or implied) of the parties with respect to the subject matter of this Agreement, including, for the avoidance of doubt, any other
employment letter or agreement, severance policy or program, or equity award agreement. 
 (e) Choice of Law. This Agreement will be
governed by the laws of the State of California without regard to California’s conflicts of law rules that may result in the application of the laws of any jurisdiction other than California. To the extent that any lawsuit is permitted under
this Agreement, Employee hereby expressly consents to the personal and exclusive jurisdiction and venue of the state and federal courts located in California for any lawsuit filed against the Executive by the Company. 

(f) Arbitration. Any and all controversies, claims, or disputes with anyone under this Agreement (including the Company and any
employee, officer, director, stockholder or benefit plan of the Company in their capacity as such or otherwise) arising out of, relating to, or resulting from the Executive’s employment with the Company Group, shall be subject to arbitration in
accordance with the provisions of the Confidentiality Agreement.

this Agreement will not affect the validity or enforceability of any other provision of this Agreement, which will remain in full force and effect. 

(h) Withholding. All payments and benefits under this Agreement will be paid less applicable withholding taxes. The Company is
authorized to withhold from any payments or benefits all federal, state, local, and/or foreign taxes required to be withheld from the payments or benefits and make any other required payroll deductions. No member of the Company Group will pay the
Executive’s taxes arising from or relating to any payments or benefits under this Agreement. 
 (i) Counterparts. This Agreement
may be executed in counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument.
