E T H : 
 WHEREAS, the Company desires to employ Executive and to enter into this Agreement embodying the terms of
such employment, and Executive desires to enter into this Agreement and to accept such employment, subject to the terms and provisions of this Agreement. 

NOW, THEREFORE, in consideration of the promises and mutual covenants contained herein and for other good and valuable consideration, the
receipt and sufficiency of which are mutually acknowledged, the Company and Executive hereby agree as follows: 
 Section 1.
Definitions. 
 Terms used herein with initial capitalization not otherwise defined are defined in Appendix A to this
Agreement. 
 Section 2. Acceptance and Term. 

The Company agrees to employ Executive, and Executive agrees to serve the Company, on the terms and conditions set forth herein for a term
(such period of employment, the “Term”) commencing immediately following the closing of the transactions contemplated by the Acquisition Agreement (the “Commencement Date”) and ending upon the
termination of Executive’s employment pursuant to Section 8 below. 
 Section 3. Position, Duties, and Responsibilities;
Place of Performance. 
 (a) Position, Duties, and Responsibilities. During the Term, Executive shall be employed and serve as the
President and Chief Executive Officer of the Company (together with such other position or positions consistent with Executive’s titles and positions as President and Chief Executive Officer of the Company as the Board shall specify from time
to time), reporting directly to the Board, and shall have such duties and responsibilities commensurate with such titles and positions as the most senior officer of the Company. Effective as of the Commencement Date, Executive shall be appointed as
a member of the Board, and thereafter, for so long as Executive is the Chief Executive Officer of the Company, the Board shall nominate Executive for election to the Board at each annual meeting of the stockholders where his term of office as a
director would expire; provided, further, that the foregoing shall not be required to the extent prohibited by legal or regulatory requirements and Executive is treated in the same manner as similarly situated directors. Executive also
agrees to serve as an officer and/or director of any other member of the Company Group, in each case without additional compensation. 







 (b) Performance. Executive shall devote Executive’s full business time, attention,
skill, and best efforts to the performance of Executive’s duties under this Agreement and shall not engage in any other business or occupation during the Term, including, without limitation, any activity that (x) conflicts with the
interests of the Company or any other member of the Company Group, (y) interferes with the proper and efficient performance of Executive’s duties for the Company, or (z) interferes with Executive’s exercise of judgment in the
Company’s best interests. Notwithstanding the foregoing, nothing herein shall preclude Executive from (i) serving, with the prior written consent of the Board, as a member of the boards of directors or advisory boards (or their equivalents
in the case of a non-corporate entity) of non-competing businesses and charitable organizations, (ii) engaging in charitable activities and community affairs, and
(iii) managing Executive’s personal investments and affairs; provided, however, that the activities set out in clauses (i), (ii), and (iii) shall be limited by Executive so as not to materially interfere, individually or
in the aggregate, with the performance of Executive’s duties and responsibilities hereunder. 
 (c) Place of Performance.
Executive acknowledges and agrees that, during the Term, he shall be required to spend sufficient time among each of the Company offices and other business locations to effectively perform his duties and responsibilities, and that frequent business
travel may be necessary. Executive shall not be required to relocate his residence in connection with his employment under this Agreement. 

Section 4. Compensation. 

During the Term, Executive shall be entitled to the following compensation: 

(a) Base Salary. Executive shall be paid an annualized Base Salary, payable in accordance with the regular payroll practices of the
Company, of not less than $550,000, with increases, if any, as may be approved in writing by the Compensation Committee; provided, however, that the foregoing shall not preclude the Compensation Committee from reducing Executive’s Base
salary as part of an across-the-board reduction applicable in like proportions to all similarly situated executives of the Company. 

(b) Annual Bonus. Executive shall be eligible for an annual incentive bonus award determined by the Compensation Committee
in respect of each fiscal year during the Term (the “Annual Bonus”). The target Annual Bonus for each fiscal year shall be 60% of Base Salary (“Target Annual Bonus”) and the maximum Annual Bonus
shall not be less than 150% of Base Salary, with the actual Annual Bonus payable being based upon the level of achievement of annual Company and specific individual performance objectives for such fiscal year, as determined by the Compensation
Committee and communicated to Executive. Executive’s Annual Bonus for 2017 shall be prorated based on the number of days worked in that year at not less than the target amount. The Annual Bonus shall be paid to Executive at the same time as
annual bonuses are generally payable to other senior executives of the Company subject to Executive’s continuous employment through the payment date except as otherwise provided for in this Agreement.

 (c) Sign-On Equity Grants. On the Commencement
Date, the Company shall grant to Executive: 
 (i) A stock option to purchase a number of shares of the Company equal to 2.25% of the fully
diluted equity capitalization of the Company as of the Commencement Date (the “Initial Stock Option Grant”), at an exercise price equal to the closing price per share of common stock on the Nasdaq on the grant date.
Subject to Executive’s continued employment with the Company through each applicable vesting date and subject to Section 8(d)(vi) hereof, twenty-five percent (25%) of the Initial Stock Option Grant will vest and become exercisable on the
first anniversary of the Commencement Date and the remainder will vest and become exercisable in substantially equal monthly installments during the three (3) year period commencing on the first anniversary of the Commencement Date, and will be
granted in the form of stock option award agreement provided to Executive with this Agreement; and 
 (ii) A restricted stock unit award for
a number of shares of the Company equal to 0.75% of the fully diluted equity capitalization of the Company as of the Commencement Date (the “Initial Restricted Stock Unit Grant”). Subject to Executive’s continued
employment with the Company through each applicable vesting date and subject to Section 8(d)(vi) hereof, twenty-five percent (25%) of the Initial Restricted Stock Unit Grant will vest and be settled on the first anniversary of the Commencement
Date and the remainder will vest and be settled in substantially equal monthly installments during the three (3) year period commencing on the first anniversary of the Commencement Date, and will be granted in the form of restricted stock unit
award agreement provided to Executive with this Agreement. The Initial Restricted Stock Unit Grant will participate in any dividends paid to stockholders of the Company during such vesting period; provided, that dividends on shares underlying
unvested restricted stock units shall be subject to the same vesting requirements as the underlying shares on which such dividends are paid and payment deferred and paid within ten (10) days after such restricted stock units become vested (and
will be forfeited to the extent unvested restricted stock are forfeited). 
 (d) Change in Control. Subject to Section 8(d)(vi)
hereof, if either of the Initial Stock Option Grant or the Initial Restricted Stock Unit Grant is not expressly assumed in a Change in Control, such award will fully vest upon such Change in Control (and participate fully with other stockholders in
such Change in Control). 
 (e) Annual Equity/LTI Grants. Executive shall be eligible for annual equity (or other long-term incentive)
grants, commencing with grants made to senior executives in fiscal year 2019, in such forms, amounts and terms as shall be determined by the Compensation Committee in its sole discretion. 

(f) Inducement Grant. The Initial Stock Option Grant and Initial Restricted Stock Unit Grant will be granted under a non-stockholder approved arrangement outside of any Company equity plan pursuant to the Nasdaq’s “inducement exception.” Executive agrees that the granting of the Initial Stock Option Grant and
Initial Restricted Stock Unit Grant is an inducement material to Executive’s decision to enter into this Agreement and accept employment with the Company.

 Section 5. Employee Benefits. 

During the Term, Executive shall be entitled to participate in health, insurance, retirement, and other benefits provided generally to
similarly situated executives of the Company. Executive shall also be entitled to the same number of holidays and sick days, as well as any other benefits, in each case as are generally allowed to similarly situated executive of the Company in
accordance with the Company policy as in effect from time to time. Executive shall be entitled to not less than four (4) weeks of vacation per year. Nothing contained herein shall be construed to limit the Company’s ability to amend,
suspend, or terminate any employee benefit plan or policy at any time without providing Executive notice, and the right to do so is expressly reserved. 

Section 6. Key-Man Insurance. 

At any time during the Term, the Company shall have the right to insure the life of Executive for the sole benefit of the Company, in such
amounts, and with such terms, as it may determine. All premiums payable thereon shall be the obligation of the Company. Executive shall have no interest in any such policy, but agrees to cooperate with the Company in procuring such insurance by
submitting to physical examinations, supplying all information required by the insurance company, and executing all necessary documents, provided that no financial obligation is imposed on Executive by any such documents. The Company shall maintain,
and instruct such insurance company and its agents to maintain, any such physical examination and other application submissions in strictest confidence. 

Section 7. Reimbursement of Business Expenses. 

During the Term, the Company shall pay (or promptly reimburse Executive) for documented, out-of-pocket expenses reasonably incurred by Executive in the course of performing Executive’s duties and responsibilities hereunder, which are consistent with the Company’s policies in effect from
time to time with respect to business expenses, subject to the Company’s requirements with respect to reporting of such expenses. The Company will pay Executive’s professional expenses incurred to negotiate and prepare this Agreement and
all other related agreements hereunder, in an amount not to exceed $15,000. 
 Section 8. Termination of Employment. 

(a) General. The Term shall terminate earlier than as provided in Section 2 hereof upon the earliest to occur of
(i) Executive’s death, (ii) a termination by reason of a Disability, (iii) a termination by the Company with or without Cause, and (iv) a termination by Executive with or without Good Reason. Upon any termination of
Executive’s employment for any reason, except as may otherwise be requested by the Company in writing and agreed upon in writing by Executive, Executive shall be deemed to have resigned from any and all directorships, committee memberships, and
any other positions Executive holds with the Company or any other member of the Company Group and hereby agrees to execute any documents that the Company (or any member of the Company Group) determines necessary to


  
 4 








 
effectuate such resignations. Notwithstanding anything herein to the contrary, the payment (or commencement of a series of payments) hereunder of any “nonqualified deferred
compensation” (within the meaning of Section 409A of the Code) upon a termination of employment shall be delayed until such time as Executive has also undergone a “separation from service” as defined in Treas. Reg. 1.409A-1(h), at which time such nonqualified deferred compensation (calculated as of the date of Executive’s termination of employment hereunder) shall be paid (or commence to be paid) to Executive on
the schedule set forth in this Section 8 as if Executive had undergone such termination of employment (under the same circumstances) on the date of Executive’s ultimate “separation from service.” 

(b) Termination Due to Death or Disability. Executive’s employment shall terminate automatically upon Executive’s death. The
Company may terminate Executive’s employment immediately upon the occurrence of a Disability, such termination to be effective upon Executive’s receipt of written notice of such termination. Upon Executive’s death or in the event that
Executive’s employment is terminated due to Executive’s Disability, Executive or Executive’s estate or Executive’s beneficiaries, as the case may be, shall be entitled to: 

(i) The Accrued Obligations; 

(ii) Any unpaid Annual Bonus in respect of any completed fiscal year that has ended prior to the date of such termination, which amount shall
be paid at such time annual bonuses are paid to other senior executives of the Company, but in no event later than the date that is two and one-half (2 1⁄2) months following the last day of the fiscal year in which such termination occurred; and 
 (iii)
A Pro Rata Bonus. 
 Following Executive’s death or a termination of Executive’s employment by reason of a Disability, except as set forth in this
Section 8(b), Executive shall have no further rights to any compensation or any other benefits under this Agreement. 
 (c)
Termination by the Company with Cause. 
 (i) The Company may terminate Executive’s employment at any time with Cause, effective
upon Executive’s receipt of written notice of such termination; provided, however, that with respect to any Cause termination relying on clause (ii) or (vi) of the definition of Cause set forth in paragraph (h) in
Appendix A to this Agreement, to the extent that such act or acts or failure or failures to act are curable, Executive shall be given not less than ten (10) days’ written notice by the Board of the Company’s intention to
terminate him with Cause, such notice to state in detail the particular act or acts or failure or failures to act that constitute the grounds on which the proposed termination with Cause is based, and such termination shall be effective at the
expiration of such ten (10) day notice period unless Executive has fully cured such act or acts or failure or failures to act that give rise to Cause during such period. 

(ii) In the event that the Company terminates Executive’s employment with Cause, Executive shall be entitled only to the Accrued
Obligations. Following such termination of Executive’s employment with Cause, except as set forth in this Section 8(c)(ii), Executive shall have no further rights to any compensation or any other benefits under this Agreement. 

  
 5 








 (d) Termination by the Company without Cause. The Company may terminate Executive’s
employment at any time without Cause, effective upon Executive’s receipt of written notice of such termination. In the event that Executive’s employment is terminated by the Company without Cause (other than due to death or Disability),
Executive shall be entitled to: 
 (i) The Accrued Obligations; 

(ii) Any unpaid Annual Bonus in respect of any completed fiscal year that has ended prior to the date of such termination, which amount shall
be paid at such time annual bonuses are paid to other senior executives of the Company, but in no event later than the date that is two and one-half (2 1⁄2) months following the last day of the fiscal year in which such termination occurred; 
 (iii) A
Pro Rata Bonus; 
 (iv) Payment of an amount equal to (x) one and one-half (1.5) (provided, such
multiple shall be equal to two (2), if the date of such termination occurs within three (3) months prior to or twelve (12) months following the consummation of a Change in Control), multiplied by (y) the sum of Base Salary plus Target
Annual Bonus, payable during the Severance Term in equal installments in accordance with the Company’s regular payroll practices; 
 (v)
To the extent permitted by applicable law without any penalty to Executive or any member of the Company Group and subject to Executive’s election of COBRA continuation coverage under the Company’s group health plan, on the first regularly
scheduled payroll date of each month of the COBRA Continuation Period, the Company will pay Executive an amount equal to the “applicable percentage” of the monthly COBRA premium cost; provided, that the payments pursuant to this
clause (v) shall cease earlier than the expiration of the COBRA Continuation Period in the event that Executive becomes eligible to receive any health benefits, including through a spouse’s employer, during the COBRA Continuation Period.
For purposes hereof, the “applicable percentage” shall be the percentage of Executive’s health care premium costs covered by the Company as of the date of termination. Amounts paid by the Company on behalf of
Executive pursuant to this clause (v) shall be imputed to Executive as additional taxable income to the minimum extent as may be required to avoid adverse consequences to Executive or the Company under either Section 105(h) of the Code or
the Patient Protection and Affordable Care Act of 2010; provided that, if such imputation does not prevent the imposition of an excise tax under, or the violation of, the Patient Protection and Affordable Care Act (as amended by the Health Care and
Education Reconciliation Act of 2010 and as amended from time to time), including, without limitation, Section 4980D of the Code, the Company shall no longer provide for payment of such medical and dental benefits to Executive (without
otherwise limiting Executive’s rights to continuation coverage under applicable law at his personal expense); and 
 (vi) If the date of
such termination occurs within twelve (12) months following the consummation of a Change in Control and any equity award previously granted to Executive and then-unvested and outstanding (including the Initial Stock Option Grant and the Initial
Restricted Stock Unit Grant) is assumed or substituted in connection with such Change in 

  
 6 








 
Control, any such equity award, that is subject to solely service-based vesting, shall become fully vested and non-forfeitable as of the date of such
termination of Executive’s employment, it being understood that if any equity award (other than the Initial Stock Option Grant or the Initial Restricted Stock Unit Grant) is not expressly assumed in a Change in Control, the treatment of the
equity award in the Change in Control shall be determined by the Compensation Committee consistent with other active senior executives; provided, that any such equity award that is subject to performance vesting requirements will be treated in all
events in the same manner as equity awards subject to performance vesting held by other senior executives. Upon any such termination prior to a Change in Control, any then unvested equity awards held by Executive shall remain outstanding but will
not vest, and will terminate and be forfeited without consideration on the three (3) month anniversary following such termination unless a Change in Control occurs during such three (3) month period; provided that if a Change in Control
occurs during the three (3) month period, the unvested equity awards held by Executive shall become vested in accordance with the terms of this Section 8(d)(vi) as though he had experienced such termination of employment on the day
immediately following such Change in Control. 
 Notwithstanding the foregoing, the payments and benefits described in clauses (ii), (iii), (iv) and
(v) above shall immediately terminate, and the Company shall have no further obligations to Executive with respect thereto, in the event that Executive breaches any provision of the Restrictive Covenant Agreement. Following such termination of
Executive’s employment by the Company without Cause, except as set forth in this Section 8(d), Executive shall have no further rights to any compensation or any other benefits under this Agreement. For the avoidance of doubt,
Executive’s sole and exclusive remedy upon a termination of employment by the Company without Cause shall be receipt of the Severance Benefits. 

(e) Termination by Executive with Good Reason. Executive may terminate Executive’s employment with Good Reason by providing the
Company ten (10) days’ written notice setting forth in reasonable specificity the event that constitutes Good Reason, which written notice, to be effective, must be provided to the Company within sixty (60) days of the occurrence of
such event. During such ten (10) day notice period, the Company shall have a cure right (if curable), and if not cured within such period, Executive’s termination will be effective upon the expiration of such cure period, and Executive
shall be entitled to the same payments and benefits as provided in Section 8(d) hereof for a termination by the Company without Cause, subject to the same conditions on payment and benefits as described in Section 8(d) hereof. Following
such termination of Executive’s employment by Executive with Good Reason, except as set forth in this Section 8(e), Executive shall have no further rights to any compensation or any other benefits under this Agreement. For the avoidance of
doubt, Executive’s sole and exclusive remedy upon a termination of employment with Good Reason shall be receipt of the Severance Benefits. 

(f) Termination by Executive without Good Reason. Executive may terminate Executive’s employment without Good Reason by providing
the Company thirty (30) days’ written notice of such termination. In the event of a termination of employment by Executive under this Section 8(f), Executive shall be entitled only to the Accrued Obligations. In the event of
termination of Executive’s employment under this Section 8(f), the Company may, in its sole and absolute discretion, by written notice accelerate such date of termination without changing the characterization of such termination as a
termination by Executive without Good Reason. Following such termination of Executive’s employment by Executive without Good Reason, except as set forth in this Section 8(f), Executive shall have no further rights to any compensation or
any other benefits under this Agreement.

 (g) Release. Notwithstanding any provision herein to the contrary, the payment of any
amount or provision of any benefit pursuant to subsection (b), (d), or (e) of this Section 8 (other than the Accrued Obligations) (collectively, the “Severance Benefits”) shall be conditioned upon Executive’s
execution, delivery to the Company, and non-revocation of the Release of Claims (and the expiration of any revocation period contained in such Release of Claims) within sixty (60) days following the date
of Executive’s termination of employment hereunder. If Executive fails to execute the Release of Claims in such a timely manner so as to permit any revocation period to expire prior to the end of such sixty (60) day period, or timely
revokes Executive’s acceptance of such release following its execution, Executive shall not be entitled to any of the Severance Benefits. Further, (i) to the extent that any of the Severance Benefits constitutes “nonqualified deferred
compensation” for purposes of Section 409A of the Code, any payment of any amount or provision of any benefit otherwise scheduled to occur prior to the sixtieth (60th) day following the
date of Executive’s termination of employment hereunder, but for the condition on executing the Release of Claims as set forth herein, shall not be made until the first regularly scheduled payroll date following such sixtieth (60th) day and (ii) to the extent that any of the Severance Benefits do not constitute “nonqualified deferred compensation” for purposes of Section 409A of the Code, any payment of any
amount or provision of any benefit otherwise scheduled to occur following the date of Executive’s termination of employment hereunder, but for the condition on executing the Release of Claims as set forth herein, shall not be made until the
first regularly scheduled payroll date following the date the Release of Claims is timely executed and the applicable revocation period has ended, after which, in each case, any remaining Severance Benefits shall thereafter be provided to Executive
according to the applicable schedule set forth herein. For the avoidance of doubt, in the event of a termination due to Executive’s death or Disability, Executive’s obligations herein to execute and not revoke the Release of Claims may be
satisfied on Executive’s behalf by Executive’s estate or a person having legal power of attorney over Executive’s affairs. 

Section 9. Restrictive Covenant Agreement. 

As a condition of, and prior to commencement of, Executive’s employment with the Company, Executive shall have executed and delivered to
the Company the Restrictive Covenant Agreement. The parties hereto acknowledge and agree that this Agreement and the Restrictive Covenant Agreement shall be considered separate contracts, and the Restrictive Covenant Agreement will survive the
termination of this Agreement for any reason. 
 Section 10. Representations and Warranties of Executive. 

Executive represents and warrants to the Company that— 

(a) Executive is entering into this Agreement voluntarily and that Executive’s employment hereunder and compliance with the terms and
conditions hereof will not conflict with or result in the breach by Executive of any agreement to which Executive is a party or by which Executive may be bound; 

  
 8 








 (b) Executive has not violated, and in connection with Executive’s employment with the
Company will not violate, any non-solicitation, non-competition, or other similar covenant or agreement of a prior employer by which Executive is or may be bound; and

 (c) in connection with Executive’s employment with the Company, Executive will not use any confidential or proprietary information
Executive may have obtained in connection with employment with any prior employer. 
 Section 11. Taxes. 

The Company may withhold from any payments made under this Agreement all applicable taxes, including but not limited to income, employment, and
social insurance taxes, as shall be required by law. Executive acknowledges and represents that the Company has not provided any tax advice to Executive in connection with this Agreement and that Executive has been advised by the Company to seek tax
advice from Executive’s own tax advisors regarding this Agreement and payments that may be made to Executive pursuant to this Agreement, including specifically, the application of the provisions of Section 409A of the Code to such
payments. 
 Section 12. Set Off; Mitigation. 

The Company’s obligation to pay Executive the amounts provided and to make the arrangements provided hereunder shall be subject to set-off, counterclaim, or recoupment of undisputed amounts owed by Executive to the Company or its affiliates; provided, however, that to the extent any amount so subject to set-off, counterclaim, or recoupment is payable in installments hereunder, such set-off, counterclaim, or recoupment shall not modify the applicable payment date of any
installment, and to the extent an obligation cannot be satisfied by reduction of a single installment payment, any portion not satisfied shall remain an outstanding obligation of Executive and shall be applied to the next installment only at such
time the installment is otherwise payable pursuant to the specified payment schedule. Executive shall not be required to mitigate the amount of any payment or benefit provided pursuant to this Agreement by seeking other employment or otherwise, and
except as provided in Section 8(d)(v) hereof, the amount of any payment or benefit provided for pursuant to this Agreement shall not be reduced by any compensation earned as a result of Executive’s other employment or otherwise. 

Section 13. Additional Section 409A Provisions. 

Notwithstanding any provision in this Agreement to the contrary— 

(a) Any payment otherwise required to be made hereunder to Executive at any date as a result of the termination of Executive’s employment
shall be delayed for such period of time as may be necessary to meet the requirements of Section 409A(a)(2)(B)(i) of the Code (the “Delay Period”). On the first business day following the expiration of the Delay
Period, Executive shall be paid, in a single cash lump sum, an amount equal to the aggregate amount of all payments delayed pursuant to the preceding sentence, and any remaining payments not so delayed shall continue to be paid pursuant to the
payment schedule set forth herein. 

  
 9 








 (b) Each payment in a series of payments hereunder shall be deemed to be a separate payment for
purposes of Section 409A of the Code. 
 (c) To the extent that any right to reimbursement of expenses or payment of any benefit in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A of the Code), (i) any such expense reimbursement shall be made by the Company no later than the
last day of the taxable year following the taxable year in which such expense was incurred by Executive, (ii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange
for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided, that the foregoing clause shall not be violated with regard to expenses reimbursed under any arrangement covered by
Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect. 

(d) While the payments and benefits provided hereunder are intended to be structured in a manner to avoid the implication of any penalty taxes
under Section 409A of the Code, in no event whatsoever shall the Company or any of its affiliates (including, without limitation, the Company) be liable for any additional tax, interest, or penalties that may be imposed on Executive as a result
of Section 409A of the Code or any damages for failing to comply with Section 409A of the Code (other than for withholding obligations or other obligations applicable to employers, if any, under Section 409A of the Code). 

Section 14. Golden Parachute Tax Provision. 

If there is a change in ownership or control of the Company that would cause any payment or distribution by the Company or any other Person or
entity to Executive or for Executive’s benefit (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise) (a “Payment”) to be subject to the excise tax imposed by
Section 4999 of the Code (such excise tax, together with any interest or penalties incurred by Executive with respect to such excise tax, the “Excise Tax”), then Executive will receive the greatest of the following,
whichever gives Executive the highest net after-tax amount (after taking into account federal, state, local and social security taxes): (a) the Payments or (b) one dollar less than the amount of the
Payments that would subject Executive to the Excise Tax (the “Safe Harbor Amount”). If a reduction in the Payments is necessary so that the Payments equal the Safe Harbor Amount and none of the Payments constitutes
nonqualified deferred compensation (within the meaning of Section 409A of the Code), then the reduction shall occur in the manner Executive elects in writing prior to the date of payment. If any Payment constitutes nonqualified deferred
compensation or if Executive fails to elect an order, then the Payments to be reduced will be determined in a manner which has the least economic cost to Executive and, to the extent the economic cost is equivalent, will be reduced in the inverse
order of when payment would have been made to Executive, until the reduction is achieved. All determinations required to be made under this Section 14, including whether and when the Safe Harbor Amount is required and the amount of the
reduction of the Payments and the assumptions to be utilized in arriving at such determination, shall be made by an independent, certified public accounting firm designated by the Company (the “Accounting Firm”). All
fees and expenses of the Accounting Firm shall be borne solely by the Company. Any determination by the Accounting Firm shall be binding upon Company and Executive. 

  
 10 








 Section 15. Clawbacks. 

All payments made pursuant to this Agreement are subject to the “clawback” obligations of Section 954 of the Dodd-Frank Wall
Street Reform and Consumer Act, as may be amended from time to time, and any other “clawback” obligations pursuant to applicable law, rule, regulation or Company policy, in each case as consistently applied to all similarly situated
executives of the Company. 
 Section 16. Successors and Assigns; No Third-Party Beneficiaries. 

(a) The Company. This Agreement shall inure to the benefit of the Company and its respective successors and assigns. Neither this
Agreement nor any of the rights, obligations, or interests arising hereunder may be assigned by the Company to a Person (other than another member of the Company Group, or its or their respective successors) without Executive’s prior written
consent (which shall not be unreasonably withheld, delayed, or conditioned); provided, however, that in the event of a sale of all or substantially all of the assets of the Company or any direct or indirect division or subsidiary
thereof to which Executive’s employment primarily relates, the Company may provide that this Agreement will be assigned to, and assumed by, the acquiror of such assets, it being agreed that in such circumstances, Executive’s consent will
not be required in connection therewith. In the event of any assignment or assumption of this Agreement or the Restrictive Covenant Agreement in connection with a sale of all or substantially all of the assets of the Company or any direct or
indirect division or subsidiary thereof to which Executive’s employment primarily relates, the scope and applicability of Executive’s noncompetition and customer nonsolicitation covenants under the Restrictive Covenant Agreement (or any
other agreement entered into by Executive and the Company prior to such sale) will be determined as of immediately prior to such sale, unless Executive shall otherwise agree or shall continue his employment pursuant to this Agreement and the
Restrictive Covenant Agreement for at least six months following such sale. 
 (b) Executive. Executive’s rights and obligations
under this Agreement shall not be transferable by Executive by assignment or otherwise, without the prior written consent of the Company; provided, however, that if Executive shall die, all amounts then payable to Executive hereunder
(including future unpaid installments thereof) shall be paid in accordance with the terms of this Agreement to Executive’s devisee, legatee, or other designee, or if there be no such designee, to Executive’s estate. 

(c) No Third-Party Beneficiaries. Except as otherwise set forth in Section 8(b) or Section 16(b) hereof, nothing expressed or
referred to in this Agreement will be construed to give any Person other than the Company, the other members of the Company Group, and Executive any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision
of this Agreement. 

  
 11 








 Section 17. Waiver and Amendments. 

Any waiver, alteration, amendment, or modification of any of the terms of this Agreement shall be valid only if made in writing and signed by
each of the parties hereto; provided, however, that any such waiver, alteration, amendment, or modification must be consented to on the Company’s behalf by the Board. No waiver by either of the parties hereto of their rights
hereunder shall be deemed to constitute a waiver with respect to any subsequent occurrences or transactions hereunder unless such waiver specifically states that it is to be construed as a continuing waiver. 

Section 18. Severability. 

If any covenants or such other provisions of this Agreement are found to be invalid or unenforceable by a final determination of a court of
competent jurisdiction, (a) the remaining terms and provisions hereof shall be unimpaired, and (b) the invalid or unenforceable term or provision hereof shall be deemed replaced by a term or provision that is valid and enforceable and that
comes closest to expressing the intention of the invalid or unenforceable term or provision hereof. 
 Section 19. Governing Law and

 Exhibit A 

EMPLOYEE NONCOMPETITION, 

NONDISCLOSURE AND DEVELOPMENTS AGREEMENT 

This Employee Noncompetition, Nondisclosure and Developments Agreement (the “Agreement”) is entered into by and between
Daniel Mark Wechsler the undersigned employee and Melinta Therapeutics, Inc., its parents, affiliates and subsidiaries (the “Company”) on the date set forth beneath the parties’ signatures (the “Effective
Date”). 
 NOW THEREFORE, in consideration of my employment by the Company pursuant to the employment agreement entered into with
the Company contemporaneous with this Agreement (“Employment Agreement”) and of the covenants herein, and for other good and valuable consideration, I hereby covenant and agree as follows: 

 

	1.	Noncompetition. 

 During the period of my employment by the Company, I shall not,
directly or indirectly, alone or as a consultant, partner, officer, director, employee, joint venturer, lender or stockholder of any entity, engage in any business or activity that is in competition with the products or services being created,
developed, manufactured, marketed, distributed or sold by the Company in (a) the United States or (b) worldwide. For the eighteen (18) month period following the termination of my employment, regardless of the reasons for my
termination, I will not engage in the management of or participation in programs at or on behalf of any entity in the business of developing, marketing or selling antimicrobial products or other specific chemical approaches or series the Company is
engaged in during my employment or in which the Company is planning to engage or has in the previous twelve (12) months engaged. In the case of areas of business unrelated to antimicrobials, for the eighteen (18) month period following the
termination of my employment, regardless of the reasons for my termination, I will not engage in the management of or participation in any such other non-antimicrobial programs which are under prosecution at
the Company, in which the Company is planning to engage or has in the immediately previous twelve (12) months engaged in, and which are directly competitive with the Company. Prohibited activities under the immediately preceding two sentences
are referred to as “Competitive” products. The foregoing provisions of this Section 1 to the contrary notwithstanding, this Section 1 shall not apply to any such entity engaged in the development, marketing or sale of
diversified products that include Competitive products if not more than twenty percent (20%) of such entity’s aggregate annual revenues for the immediately preceding eight (8) completed fiscal quarters are from the sale of Competitive
products; provided, that, I first recuse myself from, and am in no way involved with, the division of such entity that is engaged in the development, marketing or sale of any Competitive products. 

 

	2.	Nonsolicitation of Customers. 

 During the period of my employment by the Company and for
the eighteen (18) month period following the termination of my employment, regardless of the reasons for my termination, I shall not, directly or indirectly, alone or as a consultant, partner, officer, director, employee, joint venturer, lender
or stockholder of any entity, solicit or do business with any customer of the Company or any potential customer of the Company (i) with whom I have had contact or (ii) about whom I obtained information, or became familiar with through
Confidential Information (as defined in Paragraph 5), during the course of my employment with the Company, for the purpose of developing, marketing or selling Competitive products. 

 

                       
    
 Initial and Date 








	3.	Nonsolicitation of Employees. 

 (a) During the period of my employment by the Company and
for the eighteen (18) month period following the termination of my employment, regardless of the reasons for the termination, I will not, in any manner, hire or engage, or assist any company or business organization by which I am employed or
which is directly or indirectly controlled by me to hire or engage, any person who is or was employed by the Company (or is or was an individual independent contractor providing significant services to the Company) within the twelve (12) month
period prior to the date of such hiring. 
 (b) During the period of my employment by the Company and for the eighteen (18) month period
following the termination of my employment, regardless of the reasons for the termination, I will not, in any manner, solicit, recruit or induce, or assist any company or business organization by which I am employed or which is directly or
indirectly controlled by me to solicit, recruit or induce, any person who is or was employed by the Company (or is or was an individual independent contractor providing significant services to the Company) within the twelve (12) month period
prior to the date of such hiring, to leave his or her employment, relationship or engagement with the Company. 
 (c) Further, during the
period of my employment by the Company and for the eighteen (18) month period following the termination of my employment, regardless of the reasons for the termination, I shall not interfere with the Company’s relationship with any agent,
representative, contractor, project consultant or consultant then engaged by the Company. 
  

	4.	Nondisclosure. 

 I shall not at any time, whether during or after the termination of my
employment, reveal to any person or entity any Confidential Information except to (a) employees of the Company who need to know such Confidential Information for the purposes of their employment, (b) others as I reasonably determine
appropriate to discharge my duties with the Company, or (c) as otherwise authorized by the Company in writing. The term “Confidential Information” shall include any information concerning the organization, business or finances
of the Company or of any third party which the Company is under an obligation to keep confidential that is maintained by the Company as confidential. Such Confidential Information shall include, but is not limited to, trade secrets or confidential
information respecting inventions, products, designs, methods, know-how, techniques, systems, processes, specifications, blueprints, engineering data, software programs, works of authorship, customer lists,
customer information, financial information, pricing information, personnel information, business plans, projects, plans and proposals. I shall keep confidential all matters entrusted to me and shall not use or attempt to use any Confidential
Information except as may be required in the ordinary course of performing my duties as an employee of the Company, nor shall I use any Confidential Information in any manner which may injure or cause loss or may be calculated to injure or cause
loss to the Company, whether directly or indirectly.

	5.	Assignment of Developments. 

 (a) If at any time or times during my employment, I shall
(either alone or with others) make, conceive, create, discover, invent or reduce to practice any Development that (i) relates to the business of the Company or any customer of or supplier to the Company or any of the products or services being
developed, manufactured or sold by the Company or which may be used in relation therewith; or (ii) results from tasks assigned to me by the Company; or (iii) results from the use of premises or personal property (whether tangible or
intangible) owned, leased or contracted for by the Company, then all such Developments and the benefits thereof are and shall immediately become the sole and absolute property of the Company and its assigns, as works made for hire or otherwise. The
term “Development” shall mean any invention, modification, discovery, design, development, improvement, process, software program, work of authorship, documentation, formula, data, technique,
know-how, trade secret or intellectual property right whatsoever or any interest therein (whether or not patentable or registrable under copyright, trademark or similar statutes (including, but not limited to,
the Semiconductor Chip Protection Act) or subject to analogous protection). I shall promptly disclose to the Company (or any persons designated by it) each such Development. I hereby assign all rights (including, but not limited to, rights to
inventions, patentable subject matter, copyrights and trademarks) I may have or may acquire in the Developments and all benefits and/or rights resulting therefrom to the Company and its assigns without further compensation and shall communicate,
without cost or delay, and without disclosing to others the same, all available information relating thereto (with all necessary plans and models) to the Company. 

(b) Excluded Developments. I represent that the Developments identified in the Appendix, if any, attached hereto comprise all the
Developments that I have made or conceived prior to my employment by the Company and that are owned or controlled by me, which Developments are excluded from this Agreement. I understand that it is only necessary to list the title of such
Developments and the purpose thereof but not details of the Development itself. If no Developments are identified in the Appendix, it will be deemed that there are no such exclusions. 

 

	 	(gg)	6. Whistleblower; Defend Trade Secrets Act Disclosure. 

 In addition, I understand that
nothing in this Agreement shall be construed to prohibit me from reporting possible violations of law or regulation to any governmental agency or regulatory body or making other disclosures that are protected under any law or regulation, or from
filing a charge with or participating in any investigation or proceeding conducted by any governmental agency or regulatory body. 
 I
understand that the Defend Trade Secrets Act provides that I may not be held criminally or civilly liable under any Federal or state trade secret law for the disclosure of a trade secret that is made in confidence to a Federal, state, or local
government official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected violation of law; or that is made in a complaint or other document filed in a lawsuit or other proceeding, if
such filing is made under seal. In the event that I file a lawsuit for retaliation by the Company for reporting a suspected violation of law, I may disclose the trade secret to my attorney and use the trade secret information in the court
proceeding, if I file any document containing the trade secret under seal and do not disclose the trade secret, except pursuant to court order. 

  
 - 3 - 









	 	(hh)	7. Non-Disparagement. 

 During the period of my
employment by the Company, and at all times thereafter, I will not make any disparaging or defamatory comments regarding the Company or its respective current or former directors, officers, employees or shareholders in any respect or make any
comments concerning any aspect of my relationship with the Company or any conduct or events which precipitated any termination of my employment from the Company. During the period of my employment by the Company, and at all times thereafter, the
Company will not, through any authorized public statement, and will direct the Company’s officers and members of the board of directors not to make any disparaging or defamatory comments regarding me in any respect or make any comments
concerning any aspect of my relationship with the Company or any conduct or events which precipitated any termination of my employment from the Company. However, the Company’s and my obligations under this paragraph 7 shall not apply to
disclosures required by applicable law, regulation, or order of a court or governmental agency. 
  

	8.	Further Assurances. 

 I shall, during my employment and at any time thereafter, at the
request and cost of the Company, promptly sign, execute, make and do all such deeds, documents, acts and things as the Company and its duly authorized officers may reasonably require: 

(a) to apply for, obtain, register and vest in the name of the Company alone (unless the Company otherwise directs) patents, copyrights,
trademarks or other analogous protection in any country throughout the world relating to a Development and when so obtained or vested to renew and restore the same; and 

(b) to defend any judicial, opposition or other proceedings in respect of such applications and any judicial, opposition or other proceeding,
petition or application for revocation of any such patent, copyright, trademark or other analogous protection. 
 If the Company is unable,
after reasonable effort, to secure my signature on any application for patent, copyright, trademark or other analogous protection or other documents regarding any legal protection relating to a Development, whether because of my physical or mental
incapacity or for any other reason whatsoever, I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and
attorney-in-fact, to act for and in my behalf and stead to execute and file any such application or applications or other documents and to do all other lawfully
permitted acts to further the prosecution and issuance of patent, copyright or trademark registrations or any other legal protection thereon with the same legal force and effect as if executed by me. 

 

	9.	Employment At Will. 

 I understand that this Agreement does not constitute an implied or
written employment contract and that my employment with the Company is on an “at-will” basis. Accordingly, I understand that either the Company or I may terminate my employment at any time, for any
or no reason, subject to the terms of my Employment Agreement. 

  
 - 4 - 









	10.	Severability. 

 I hereby agree that each provision and the subparts of each provision
herein shall be treated as separate and independent clauses, and the unenforceability of any one clause shall in no way impair the enforceability of any of the other clauses of this Agreement. Moreover, if one or more of the provisions contained in
this Agreement shall for any reason be held to be excessively broad as to scope, activity, subject or otherwise so as to be unenforceable at law, such provision or provisions shall be construed by the appropriate judicial body by limiting or
reducing it or them, so as to be enforceable to the maximum extent compatible with the applicable law as it shall then appear. I hereby further agree that the language of all parts of this Agreement shall in all cases be construed as a whole
according to its fair meaning and not strictly for or against either of the parties. 
 11. Amendments; Waiver. 

Any amendment to or modification of this Agreement, or any waiver of any provision hereof, shall be in writing and signed by the Company. Any
waiver by the Company of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any subsequent breach of such provision or any other provision hereof. 

 

	12.	Survival. 

 This agreement shall be effective as of the Effective Date. The parties
obligations under this Agreement shall survive the termination of my employment regardless of the manner of such termination, in accordance with the terms hereof, and shall be binding, respectively, upon the Company’s successors and assigns and
on my heirs, executors, administrators and legal representatives. 
  

	13.	Assignment. 

 The Company shall have the right to assign this Agreement to its successors
and assigns, and all covenants and agreements hereunder shall inure to the benefit of and be enforceable by said successors or assigns. I may not assign this Agreement. 
  

	14.	Representations. 

 (a) I represent that my employment with the Company and my performance
of all of the terms of this Agreement do not and will not breach any agreement to keep in confidence proprietary information acquired by me in confidence or in trust prior to my employment by the Company. I have not entered into, and I shall not
enter into, any agreement either written or oral in conflict herewith. I agree that in the course of my employment with the Company, if the Company requests that I undertake activities that will cause me to use Confidential Information of my prior
employer, I will inform the Company of that fact. 

  
 - 5 - 








 (b) I agree that the restrictions set forth in this Agreement are reasonable and necessary to
protect specific business interests of the Company. I agree that any breach of this Agreement by me will cause irreparable damage to the Company and that in the event of such breach the Company shall have, in addition to any and all remedies of law,
the right to an injunction, specific performance or other equitable relief to prevent the violation of my obligations hereunder. The Company may apply for such injunctive relief in any court of competent jurisdiction without the necessity of posting
any bond or other security. 
  

	15.	Governing Law; Forum Selection Clause. 

 This Agreement and any claims arising out of
this Agreement (or any other claims arising out of the relationship between the parties) shall be governed by and construed in accordance with the laws of the State of Delaware and shall in all respects be interpreted, enforced and governed under
the internal and domestic laws of such state, without giving effect to the principles of conflicts of laws of such state. Any claims or legal actions by one party against the other shall be commenced and maintained in any state or federal court
located in such state, and I hereby submit to the jurisdiction and venue of any such court. 
  

	16.	Entire Agreement. 

 This Agreement sets forth the complete, sole and entire agreement
between the parties on the subject matter herein and supersedes any and all other agreements, negotiations, discussions, proposals, or understandings, whether oral or written, previously entered into, discussed or considered by the parties

myself and my heirs, administrators, executors, and assigns, effective as of the date on which this release becomes effective pursuant to its terms, do fully and forever release, remise, and discharge each of the Company and each of its direct and
indirect subsidiaries and affiliates, and their respective successors and assigns, together with their respective current and former officers, directors, partners, shareholders, employees, and agents (collectively, and with the Company,
the “Group”), from any and all claims whatsoever up to the date hereof that I had, may have had, or now have against the Group, whether known or unknown, for or by reason of any matter, cause, or thing whatsoever,
including any claim arising out of or attributable to my employment or the termination of my employment with the Company, whether for tort, breach of express or implied employment contract, intentional infliction of emotional distress, wrongful
termination, unjust dismissal, defamation, libel, or slander, or under any federal, state, or local law dealing with discrimination based on age, race, sex, national origin, handicap, religion, disability, or sexual orientation. The release of
claims in this Release includes, but is not limited to, all claims arising under the Age Discrimination in Employment Act of 1967 (“ADEA”), Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act of
1990, the Civil Rights Act of 1991, the Family and Medical Leave Act of 1993, the Employee Retirement Income Security Act of 1974, as amended, the Worker Adjustment and Retraining Notification Act of 1988 and the Equal Pay Act of 1963, each as may
be amended from time to time, and all other federal, state, and local laws, the common law, and any other purported restriction on an employer’s right to terminate the employment of employees. The release contained herein is intended to be a
general release of any and all claims to the fullest extent permissible by law and for the provisions regarding the release of claims against the Group to be construed as broadly as possible, and hereby incorporate in this release similar federal,
state or other laws, all of which I also hereby expressly waive. 
 I understand and agree that claims or facts in addition to or different
from those which are now known or believed by me to exist may hereafter be discovered, but it is my intention to fully and forever release, remise and discharge all claims which I had, may have had, or now have against the Group, whether known or
unknown, suspected or unsuspected, asserted or unasserted, contingent or noncontingent, without regard to the subsequent discovery or existence of such additional or different facts. Without limiting the foregoing, by signing this Release, I
expressly waive and release any provision of law that purports to limit the scope of a general release. 
 I acknowledge and agree that as
of the date I execute this Release, I have no knowledge of any facts or circumstances that give rise or could give rise to any claims under any of the laws listed in the preceding paragraphs. 

  
 B-1 








 By executing this Release, I specifically release all claims relating to my employment and its
termination under the ADEA, a United States federal statute that, among other things, prohibits discrimination on the basis of age in employment and employee benefit plans. 

Notwithstanding any provision of this Release to the contrary, by executing this Release, I am not releasing (i) any claims relating to
my rights under Section 8 of my Employment Agreement, (ii) any claims that cannot be waived by law, or (iii) my right of indemnification and coverage under Company directors and officers liability insurance under Section 20 of my
Employment Agreement. 
 I expressly acknowledge and agree that I – 

• Am able to read the language, and understand the meaning and effect, of this Release; 

• Have no physical or mental impairment of any kind that has interfered with my ability to read and understand the meaning
of this Release or its terms, and that I am not acting under the influence of any medication, drug, or chemical of any type in entering into this Release; 

• Am specifically agreeing to the terms of the release contained in this Release because the Company has agreed to pay me
the Severance Benefits in consideration for my agreement to accept it in full settlement of all possible claims I might have or ever have had, and because of my execution of this Release; 

• Acknowledge that, but for my execution of this Release, I would not be entitled to the Severance Benefits; 

• Understand that, by entering into this Release, I do not waive rights or claims under the ADEA that may arise after the
date I execute this Release; 
 • Had or could have had [twenty-one
(21)][forty-five (45)]1 calendar days from the date of my termination of employment (the “Release Expiration Date”) in which to review and consider this Release, and
that if I execute this Release prior to the Release Expiration Date, I have voluntarily and knowingly waived the remainder of the review period; 

• Have not relied upon any representation or statement not set forth in this Release or my Employment Agreement made by
the Company or any of its representatives; 
  

	1 	To be selected based on whether applicable termination was “in connection with an exit incentive or other employment termination program” (as such phrase is defined in the Age Discrimination in Employment Act
of 1967). 


  
 B-2 








 • Was advised to consult with my attorney regarding the terms and effect of
this Release; and 
 • Have signed this Release knowingly and voluntarily. 

I represent and warrant that I have not previously filed, and to the maximum extent permitted by law agree that I will not file, a complaint,
charge, or lawsuit against any member of the Group regarding any of the claims released herein. If, notwithstanding this representation and warranty, I have filed or file such a complaint, charge, or lawsuit, I agree that I shall cause such
complaint, charge, or lawsuit to be dismissed with prejudice and shall pay any and all costs required in obtaining dismissal of such complaint, charge, or lawsuit, including without limitation the attorneys’ fees of any member of the Group
against whom I have filed such a complaint, charge, or lawsuit. This paragraph shall not apply, however, to a claim of age discrimination under the ADEA or to any non-waivable right to file a charge with the
United States Equal Employment Opportunity Commission (the “EEOC”) or similar state agency; provided, however, that if the EEOC or similar state agency were to pursue any claims relating to my employment
with the Company, I agree that I shall not be entitled to recover any monetary damages or any other remedies or benefits as a result and that this Release and Section 8 of my Employment Agreement will control as the exclusive remedy and full
settlement of all such claims by me. 
 I hereby agree to waive any and all claims to re-employment
with the Company or any other member of the Group and affirmatively agree not to seek further employment with the Company or any other member of the Group. I acknowledge that if I re-apply for or seek
employment with the Company or any other member of the Group, the Company’s or any other member of the Group’s refusal to hire me based on this provision will provide a complete defense to any claims arising from my attempt to apply for
employment. 
 Notwithstanding anything contained herein to the contrary, this Release will not become effective or enforceable prior to the
expiration of the period of seven (7) calendar days immediately following the date of its execution by me (the “Revocation Period”), during which time I may revoke my acceptance of this Release by notifying the
Company and the Board of Directors of the Company, in writing, delivered to the Company at its principal executive office, marked for the attention of its Chairman of the Board. To be effective, such revocation must be received by the Company no
later than 11:59 p.m. Eastern Time on the seventh (7th) calendar day following the execution of this Release. Provided that this Release is executed and I do not revoke it during the
Revocation Period, the eighth (8th) calendar day following the date on which this Release is executed shall be its effective date. I acknowledge and agree that if I revoke this Release during the
Revocation Period, this Release will be null and void and of no effect, and neither the Company nor any other member of the Group will have any obligations to pay me the Severance Benefits. 

The provisions of this Release shall be binding upon my heirs, executors, administrators, legal personal representatives, and assigns. If any
provision of this Release shall be held by any court of competent jurisdiction to be illegal, void, or unenforceable, such provision shall be of no force or effect. The illegality or unenforceability of such provision, however, shall have no effect
upon and shall not impair the enforceability of any other provision of this Release.

NO CLAIM (INCLUDING ANY CLAIM RELATED TO TERMS OR CONDITIONS OF MY EMPLOYMENT WITH OR COMPENSATION PAID BY THE COMPANY, OR ANY CHANGE IN OR TERMINATION OF MY EMPLOYMENT) MAY BE LITIGATED OR ARBITRATED ON A CLASS OR COLLECTIVE BASIS. I ALSO HEREBY
WAIVE ANY RIGHT TO SUBMIT, INITIATE, OR PARTICIPATE IN A REPRESENTATIVE CAPACITY OR AS A PLAINTIFF, CLAIMANT, OR MEMBER IN A CLASS ACTION, COLLECTIVE ACTION, OR OTHER REPRESENTATIVE OR JOINT ACTION AGAINST THE COMPANY, REGARDLESS OF WHETHER THE
