whichever is greater, for the remainder of the existing term of this Agreement, without any further renewal or continuation, provided that such amount shall be not less than the sum of such salary and bonus pro rated for a 18-month period, or
(B) to remain an employee of the Company for a period (as determined by Employee) of up to 18 months following the date notice of termination is given by Employee pursuant to Section 5(a), in which case Employee shall be relieved of his or

the Change in Control, whichever is greater, and annual bonus in respect of such period (in each case payable within 30 days after the end of the respective calendar year and prorated for any portion of a year), each such bonus to be based on an

such employment or the effective date of such termination as specified by Employee in such notice, and shall be entitled to receive, subject to the terms thereof, all benefits due to Employee under the provisions of any Benefit Plan and a discounted
lump sum cash payment for the balance of the salary and bonus Employee would have been entitled to receive pursuant to this Section 5(b)(B) had Employee remained on the Company’s payroll until the end of the Initial Term or such 18 month
period whichever is greater, provided, further, however, that Employee shall not be entitled to receive any such lump sum cash payment if he or she accepts full-time employment with any subsidiary or Affiliate of the Company. For

 In addition, whether Employee elects 5(b)(A) or 5(b)(B), for a period of the earlier of one year from the
date of termination of employment or the date Employee is eligible to receive health benefits by virtue of other employment, Employee shall receive continued eligibility and enrollment (including family coverage, if any), without a premium charge
therefor, in hospital, medical and dental insurance plans providing substantially equivalent benefit coverage to those plans in which Employee was enrolled immediately prior to the Change in Control unless waived in writing by Employee (or, in the
event such coverage cannot be provided, substantially similar benefits). 
 Any lump sum payments required to be made pursuant to this
Section 5(b) shall be discounted to present value from the times at which such amounts would have been paid absent any such termination at an annual discount rate for the relevant period equal to the “applicable Federal rate” (within
the meaning of Section 1274(d) of the Internal Revenue Code of 1986 (the “Code”)), compounded semi-annually, in effect on the date of such termination, the use of which rate is hereby elected by the Company and Employee pursuant to
Treas. Reg. § 1.28OG- I Q/A32 (provided that in the event such election is not permitted, such other rate determined as of such other date as is applicable for determining present value under Section 28OG of the Code shall be used).

 6. Termination by Company. 
 (a) For Cause. Provided that notice of termination has not previously been given under any other Section hereof, the Company shall have the right to terminate Employee’s employment for cause upon written
notice to Employee at any time. In such event, Employee’s employment with the Company shall terminate immediately and Employee shall be entitled to receive (i) any earned and unpaid salary accrued through the date of such termination, and
(ii) subject to the terms thereof, any benefits which may be due to Employee under the provisions of any Benefit Plan. Employee hereby disclaims any right to receive a pro rata portion of his or her annual bonus with respect to the year in
which such termination occurs. For purposes hereof, “cause” shall mean termination by action of the Company’s Board of Directors or any committee thereof because of Employee’s conviction (treating a nolo & contendere
plea as a conviction) of a felony (whether or not any right to appeal has been exercised) or willful refusal without proper cause to perform his or her obligations under this Agreement or because of Employee’s material breach of the covenants
provided for in Sections 10, 11 and 12 of this Agreement. In the event (i) such termination is because of the Employee’s willful refusal without proper cause to perform any one or more of his obligations under this Agreement (ii) such
notice is the first such notice of termination for any reason delivered by the Company to the Employee under this Section 6(a), and (iii) within I 0 days following the date of such notice the Employee shall cease his or her refusal and
shall use his or her best efforts to perform such obligations, the termination shall not be effective. 
 (b) Other. Provided that notice of
termination has not previously been given under any other Section hereof, the Company shall have the right at any time to terminate Employee’s employment under this Agreement without cause, by giving written notice thereof to Employee.

  

 4 

 (i) If such notice is so given to Employee, Employee shall be entitled to receive subject to the terms
thereof, all benefits which may be due to Employee under the provisions of any Benefit Plan and to elect, within 30 days after receiving such notice, to receive either a lump sum severance payment in the amount, and upon the terms and conditions,
provided in Section 5(b)(A) and calculated as set forth in the last paragraph of Section 5(b), or to remain an employee of the Company upon the terms and conditions provided in Section 5(b)(B); provided, however, that
(i) any reference therein to Section 5(a) shall be deemed for purposes of this Section 6(b) to be a reference to this Section 6(b)(i), and (ii) if a Change in Control has not occurred, then (x) Employee’s salary
shall be determined with reference to his or her then current annual salary and (y) Employee’s annual bonus shall equal at least the Employee’s target amount immediately prior to Employee’s termination under this
Section 6(b)(i). 
 (ii) For the period beginning when Employee receives notice of termination from the Company pursuant to this
Section 6(b), and ending six months thereafter, Employee will, without charge to Employee, have use of reasonable office space and reasonable office Facilities at Employee’s principal job location immediately prior to his or her
termination of employment, or other location reasonably close to such location, together with reasonable secretarial services in each case appropriate to an employee of Employee’s position and responsibilities prior to such termination of
employment but taking into account Employee’s reduced need for such office space and secretarial services. Employee will continue to be eligible to participate in the Company’s Benefit Plans and to receive, subject to the terms thereof,
all benefits, which are received by other employees at Employee’s level thereunder other than options or similar equity-based or incentive awards. 
 (iii) In the event that Employee’s employment is terminated prior to the occurrence of a Change in Control, or more than three years following a Change in Control, then, in partial consideration for the
Company’s obligation to make the payments described in this Section 6(b), Employee shall execute and deliver to the Company a release in the form as set forth in Exhibit A. The Company shall deliver such release to Employee at the time the
Company delivers notice of termination pursuant to this Section 6(b). Employee shall execute and deliver such release to the General Counsel of the Company within 21 days of receipt of notice of termination. If Employee shall fail to execute
and deliver to the Company such release within 30 days of Employee’s receipt thereof from the Company, Employee’s employment with the Company shall terminate effective at the end of such 30-day period and Employee shall receive, in lieu of
the severance arrangements described in Section 6(b), a lump sum cash payment in an amount determined in accordance with the personnel policies of the Company then applicable.

 7. Death; Disability. 
 (a) Death. If Employee shall die while employed by the Company, Employee’s employment under this Agreement shall thereupon terminate
and Employee’s estate or beneficiaries, as the case may be, shall be entitled to receive as promptly as practicable but in any event within 30 days after reasonably satisfactory evidence of Employee’s death is received by the Company
(i) any earned and unpaid salary accrued to Employee through the period ending 30 days following the date of Employee’s death and a pro rata portion of the target annual bonus amount in effect immediately prior to Employee’s death;

this Agreement upon written notice to Employee at any time and thereupon Employee shall be entitled to receive (i) any earned and unpaid salary accrued through the date of such termination; (ii) subject to the terms thereof, any benefits
which may be due to Employee under the provisions of any Benefit Plan; and (iii) a lump sum cash payment equal to the sum of 75% of Employee’s then current annual salary and then applicable target annual bonus amount prorated for a
18-month period, less the amount of any disability insurance proceeds payable to Employee under any disability insurance policy or program covering Employee. 
 8. Stock Options and Other Incentive Awards. Upon Employee’s termination of employment with the Company for any reason, Employee’s rights to benefits and payments under any stock options,
restricted shares or other incentive plans shall be determined in accordance with the terms and provisions of such plans and any agreements under which such stock options, restricted shares or other awards were granted. 
 9. Change in Control. For purposes of this Agreement, a “Change in Control” of the Company shall be deemed to have occurred at
such time as the Founding Stockholders (and their respective affiliates) as a group cease to have the ability to elect a majority of the directors on the Board of Directors of the Company (other than the chief executive officer of the Company and
independent directors; provided that independent directors shall be included in calculating whether the foregoing majority requirement is satisfied if the directors nominated by the Founding Stockholders (and their respective affiliates) do not
constitute a majority of the committee that selects the Board of Director’s nominees for independent directors) and a “person” or “group” (within the meaning of Sections 13(d) and 14(d)(2) of the Securities Exchange Act of
1934, as amended (the “Exchange Act) (other than the Founding Stockholders and their respective affiliates) has become the ultimate “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act) of more than 35% of the total
voting power of the voting interests of the Company on a fully diluted basis and such ownership represents a greater percentage of the total voting power of the voting interests of the Company, on a fully diluted basis, than is held by the Founding
Stockholders (and their respective affiliates) as a group on such date.

terms used in this Sixth Amendment shall have the meanings ascribed to them in the Lease. 
 2. Demise of the Premises. As of
the Effective Date, Section 1.01 of the Lease is hereby amended by adding the following paragraph: 
 “Landlord hereby leases,
demises and lets to Tenant and Tenant hereby leases and takes from Landlord those certain additional premises (hereinafter sometimes called the “Fifth Floor Expansion Premises”) located on the fifth floor of the Building (being
Suite 510). A floor plan of the Fifth Floor Expansion Premises is attached hereto and made a part hereof for all purposes as Exhibit BVI. Upon the Fifth Floor Expansion Commencement Date, any reference to the “Premises” in
the Lease and in the Sixth Amendment shall incorporate the Fifth Floor Expansion Premises, thereby including both the Current Premises and the Fifth Floor Expansion Premises; provided, however, that the payment of Base Rental and Additional Rental
for the Fifth Floor Expansion Premises only shall not commence until the Fifth Floor Expansion Rent Commencement Date.” 

 3. Rentable Area. As of the Effective Date, Section 1.03 of the Lease is hereby
amended by deleting the paragraph added to Section 1.03 of the Lease pursuant to the Fifth Amendment and adding the following paragraph: 
 “Landlord and Tenant stipulate and agree for all purposes that (i) the Rentable Area of the Fifth Floor Expansion Premises is 3,263 square feet, (ii) the Rentable Area of the Fifth Amendment Expansion Premises is 10,276

Expansion Premises as of the Fifth Floor Expansion Commencement Date through the Expiration Date (“Fifth Floor Expansion Premises Term”). If the term of the Fifth Floor Expansion Commencement Date commences on other than the first
day of a calendar month, then the installments of Base Rental and Additional Rental for such month shall be prorated and the installment so prorated shall be paid in advance on the Fifth Floor Expansion Commencement Date. The payment for such
prorated month shall be calculated by multiplying the monthly installment of Base Rental and Additional Rental by a fraction, the numerator of which shall be the number of days of the Fifth Floor Expansion Premises Term occurring during said
commencement month, and denominator of which shall be the total number of days occurring in said commencement month.
