AND GENERAL RELEASE AGREEMENT


 


THIS
SEPARATION AND GENERAL RELEASE AGREEMENT (this “Separation Agreement”) is entered into between Dr. Mark
A. Tepper, with an address at __________________________ (the “Employee”) and CORBUS
PHARMACEUTICALS HOLDINGS, INC., having an office at 500 River Ridge Drive, Norwood, MA 02062 (hereinafter
“Corbus,” “the “Employer” or the “Company”). Employer,
together with its past, present and future direct and indirect parent organizations, subsidiaries, affiliated entities,
professional employer organizations, related companies and divisions and each of their respective past, present and future
officers, directors, employees, shareholders, trustees, members, partners, attorneys and agents (in each case, individually
and their official capacities), and each of their respective employee benefit plans (and such plans’ fiduciaries,
agents, administrators and insurers, in their individual and their official capacities), as well as any predecessors, future
successors or assigns or estates of any of the foregoing, is collectively referred to in this Separation Agreement as
the “Released Parties.”


 


A.
Corbus and Employee entered into an amended and restated employment agreement, dated April 11, 2018 (the “Employment
Agreement”).


 


B.
Corbus and Employee have engaged in discussions regarding a termination of Employee’s employment with the Employer and desire
to settle all matters between them by entering into this Separation Agreement and associated Consulting Agreement annexed hereto
and being entered into contemporaneously herewith (“Consulting Agreement”) on the terms and conditions set
forth herein and therein.


 


In
consideration of the foregoing premises, the mutual covenants and agreements contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto, intending to be legally bound,
hereby agree as follows:


 


1.
Separation of Employment. Employee and Corbus have mutually agreed to terminate the Employment Agreement, except that sections
6 (Confidentiality), 7 (Assignment of Work Product), and 8 (Non-Competition; Non-Solicitation) thereof (the “Covenants”)
shall survive according to their terms, and remain in full force and effect. Employee acknowledges, confirms and agrees that his
last day of employment with Corbus was March 31, 2019 (the “Separation Date”). Except with respect to the Covenants,
the Employment Agreement is hereby superseded and terminated by this Separation Agreement and the Consulting Agreement being entered
contemporaneously with the execution of this Agreement. To the extent any of the Covenants are inconsistent or conflict with the
obligations of Employee under the Consulting Agreement, the substantive terms of the Consulting Agreement shall apply. In the
event any terms or conditions of the Consulting Agreement are held unenforceable, the terms of the Covenants shall apply. Employee
shall be deemed to have voluntarily resigned (effective as of the Separation Date) (a) from any position with Corbus or any of
its affiliates, including, but not limited to, an officer of Corbus or any of its affiliates. Employee further acknowledges that,
except as otherwise specifically provided in this Separation Agreement and the Consulting Agreement, Employee has received all
compensation and benefits to which Employee is entitled under the Employment Agreement or otherwise as a result of Employee’s
employment. Employee and Corbus acknowledge and agree that the compensation and benefits provided in this Separation Agreement
and Consulting Agreement exceed the compensation and benefits set forth in Employees’ Employment Agreement with respect
to severance and continued benefits following termination, which Employee foregoes in consideration of executing this Separation
Agreement and Consulting Agreement. Employee understands that, except as otherwise provided in this Separation Agreement and the
Consulting Agreement, Employee is entitled to nothing further from the Released Parties, including reinstatement by Employer.
Employee will be reimbursed within thirty (30) days of the Separation Date for business-related expenses outstanding as of the
Separation Date in accordance with the Company’s expense reimbursement policy.


 




    	 	 	 



    	 	 	 



    

 


2.
Employee General Release of Released Parties. In consideration of the payment and benefits set forth in Section 4
below, Employee (on his own behalf and on behalf of his heirs, executors, administrators, trustees, legal representatives, successors
and assigns) hereby unconditionally and irrevocably releases, waives, discharges and gives up, to the full extent permitted by
law, any and all Claims (as defined below) that Employee may have against any of the Released Parties arising on or prior to the
date of Employee’s execution and delivery of this Separation Agreement to Employer. “Claims” means any

and emotional harm, arising, directly or indirectly, out of any promise, agreement, offer letter, contract, understanding, common
law, tort, the laws, statutes, and/or regulations of the Commonwealth of Massachusetts, or any other state or municipality and
the United States, including, but not limited to, federal and state wage and hour laws (to the extent waiveable), federal and
state whistleblower laws, Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1991, the Equal Pay Act, the Lilly
Ledbetter Fair Pay Act of 2009, the Americans with Disabilities Act, the Family and Medical Leave Act, the Employee Retirement

each case, as such laws have been or may be amended, as each may be amended from time to time, whether arising directly or indirectly
from any act or omission, whether intentional or unintentional. This releases all Claims including those of which Employee is
not aware and those not mentioned in this Separation Agreement at the time of termination. Employee specifically releases any
and all Claims arising out of Employee’s employment with Employer or termination therefrom. Employee expressly acknowledges
and agrees that, by entering into this Separation Agreement, Employee is releasing and waiving any and all rights or Claims including,
without limitation, Claims that Employee may have arising under ADEA, which have arisen on or before the date of Employee’s
execution and delivery of this Separation Agreement to Employer. This general release of claims does not apply to, waive or

compensation claim); claims for unemployment benefits or any other claims or rights that by law cannot be waived in a private
agreement between an employer and employee; or your rights to any vested benefits to which you are entitled under the terms of
the applicable employee benefit plan (the “Excluded Claims”).


 




    	 	 	 



    	 	 	 



    

 


3.
Representations; Covenant not to Sue. Employee hereby represents and warrants that (A) Employee has not filed, caused or
permitted to be filed any pending proceeding (nor has Employee lodged a complaint with any governmental or quasi-governmental
authority) against any of the Released Parties, nor has Employee agreed to do any of the foregoing, (B) Employee has not assigned,
transferred, sold, encumbered, pledged, hypothecated, mortgaged, distributed, or otherwise disposed of or conveyed to any third
party any right or Claim against any of the Released Parties that has been released in this Separation Agreement, and (C) Employee
has not directly or indirectly assisted any third party in filing, causing or assisting to be filed, any Claim against any of
the Released Parties. Except as set forth in Section 13 below, Employee covenants and agrees that Employee shall not encourage
or solicit or voluntarily assist or participate in any way in the filing, reporting or prosecution by himself or any third party
of a proceeding or Claim against any of the Released Parties arising on or prior to the date of Employee’s execution and
delivery of this Separation Agreement or with respect to any shareholders derivative, shareholder class action, corporate fraud,
corporate waste or similar action at any time during which Employee is receiving Benefits as defined hereunder.


 


4.
Payment and Benefits. Notwithstanding the language contained in the Employment Agreement, the parties have mutually agreed
that, as good consideration for Employee’s execution, delivery, non-revocation, and full compliance with the terms of this
Separation Agreement, Employer shall provide Employee with the following, all collectively referred to herein as “Benefits”:


 


(A)
Engagement by the Company as a Senior Scientific Advisor for a period of eighteen (18) months on the terms set forth in the Consulting
Agreement annexed hereto (the “Consulting Agreement”).


 


(B)
Provided Employee timely elects COBRA, Employer will pay the monthly premium necessary to secure continued health, dental, and
vision insurance coverage under COBRA beginning on the Separation Date through the eighteen (18) month anniversary of the Separation
Date such that there is no interruption in Employee’s health, dental, and vision insurance coverage; provided that neither
this Agreement nor the Consulting Agreement have been terminated for Cause (as defined in the Consulting Agreement). Should Employee
fail or refuse to timely elect COBRA coverage, Employer will have no obligation under this paragraph. Employee understands and
acknowledges that if Employee elects COBRA coverage, coverage through the Health Insurance Marketplace (also known as healthcare
exchanges) (the “Marketplace”) generally will not be available until the next annual open enrollment period
offered by the Marketplace. Accordingly, you understand and acknowledge that the opportunity for you to obtain possibly less expensive
coverage through the Marketplace may not be available until the following January 1;


 


(C)
Continued vesting of stock options granted to Employee prior to the Separation Date during the term of the Consulting Agreement
in accordance with the terms of the option grants.


 




    	 	 	 



    	 	 	 



    

 


(D)
An extension of the period of time that Employee may exercise stock options granted to the Employee that have vested as of the
Separation Date (the “Vested Options”) from 90 days to December 31, 2021 (or sooner expiration of their term).
Any Vested Options not exercised on or before December 31, 2021 will be canceled and be of no further force or effect. Any stock
options that remain unvested following expiration or termination of the Consulting Agreement will be canceled and be of no further
force or effect.


 


(E)
Reimbursement of attorneys’ fees incurred by Employee in connection with the negotiation of this Agreement and the Consulting
Agreement in an amount not to exceed Ten Thousand Dollars ($10,000).


 


Other
than pursuant the terms set forth in the Separation Agreement and Consulting Agreement, Employee acknowledges that Employee is
not otherwise entitled to receive the Benefits set forth in this Section 4 and acknowledges that nothing in this Separation
Agreement shall be deemed to be an admission of liability on the part of any of the Released Parties. Employee agrees that Employee
will not seek anything further from any of the Released Parties beyond that which is set forth in this Separation Agreement and
associated Consulting Agreement.


 


5.
Who is Bound. Employer and Employee are bound by this Separation Agreement. Anyone who succeeds to Employee’s rights
and responsibilities, such as the executors of Employee’s estate, is bound and anyone who succeeds to Employer’s rights
and responsibilities, such as its successors and assigns, is also bound.


 


6.
Restrictions on Sale of Company Stock. As an inducement for Employer
agreeing to extend the expiration date of Employee’s vested stock options and for the other good and valuable consideration
set forth in this Separation Agreement, Employee hereby acknowledges, agrees and covenants that except as set forth in this Section
6, Employee will not (i) offer, sell, contract to sell, pledge as collateral, transfer, grant any option to purchase or otherwise
dispose of (collectively, a “Disposition”) any shares of Employer’s common stock prior to later of (a)
Ninety One (91) days after the Separation Date (the “Disposition Date”) or (b) the date of any lock up agreements
to which Employee is a party expire and (ii) exercise or seek to exercise or effectuate in any manner any rights of any nature
that Employee has or may have hereafter to require Employer to register under the Securities Act of 1933, as amended (the “Act”).
Except to the extent such sales are restricted pursuant to the preceding sentence, on or after the Disposition Date, Employee
may sell up to and no more than 250,000 shares of Employer common stock per calendar quarter during the term of the Consulting
Agreement.


 


7.
Securities Law. Employee understands that
he will continue to be deemed an affiliate for a period of three months after the Separation Date up through and including the
Disposition Date under applicable federal securities laws and therefore the restrictive legends on any shares of common stock
that Employee owns will not be removed at least until the Disposition notwithstanding this, Employer will make commercially reasonable
efforts to remove the restrictive legends on all Employee’s shares of common stock as soon as possible but no later than
two (2) weeks following the Disposition Date or as soon thereafter as possible. Employee acknowledges and understands that even
after the Disposition Date, Employee is still unable to trade in Corbus securities if Employee is in possession of material, non-public
information. Compliance with insider-trading law is Employee’s responsibility, and given the potentially severe penalties
for violations, Employee should take extra care and seek his own advice on trading. In addition, in accordance with Section 16
of the Exchange Act of 1934, as amended, Employee may be subject to reporting obligations with respect to Corbus securities, including
option exercises, open-market purchases or sales, and short-swing profit rules and such obligations may continue for up to six
months after his Separation Date. Employee shall inform Employer of any transactions that require SEC filings so Employer can
assist with any required Form 4 or 13G filings.


 




    	 	 	 



    	 	 	 



    

 


8.

individuals retained by the Employee during the course of his employment, the names of all individuals not employed by the Employer
relating to the work of the Employer, along with a brief description of the individuals work for or on behalf of the Employer,
and any and all other information in Employee’s possession related to the work of the Employer reasonably necessary to ensure
continued operation of the Employer’s business. The Employee shall The Employee shall collate and transcribe all information
and transfer to Employer within thirty (30) days of execution of this Agreement (or such other date as may be agreed to between
Employee and Employer) and shall make himself reasonably available to participate in calls with Employer’s Board of Directors
and other employees of Employer to discuss and disclose any relevant information. Except for calls in which the Employer’s
Board of Directors or officers participate, the Employee shall not contact any such consultants, advisors, and other individuals
retained by the Employee during the course of his employment with the Employer for purposes of discussing the Employer or the
transition. To the extent such consultants, advisors, and other individuals contact Employee to discuss Corbus or the transition,
Employee will direct such consultants, advisors, and other individuals to contact Brian Murphy at bmurphy@corbuspharma.com;
617-963-0100.


 


(C)

the best of his ability, by providing truthful information and/or testimony, in any Employer investigation, litigation, arbitration,
or regulatory proceeding regarding events that occurred during Employee’s tenure with Employer. Employee will make himself
reasonably available to consult with Employer’s counsel, to provide information, and to appear to give testimony. Employer
will, to the extent permitted by law and applicable court rules, reimburse Employee for reasonable out-of-pocket expenses Employee
incurs in extending such cooperation, so long as Employee provides advance written notice of Employee’s request for reimbursement
and provides satisfactory documentation of the expenses. To the extent permitted by law, if Employee extends such cooperation
after the term of the Consulting Agreement the Employee will be compensated for time actually spent in providing such cooperation
at an hourly rate equivalent to his compensation under the Consulting Agreement. Nothing in this Section 8(C) is intended
to and shall not preclude or limit your preserved rights described in Section 13.

for any reason be held unenforceable in any respect under the law of any state of the United States or the United States, such
unenforceability shall not affect any other provision of this Separation Agreement but this Separation Agreement shall then be
construed as if such unenforceable provision or provisions had never been contained herein or therein. If it is ever held that
any restriction hereunder is too broad to permit enforcement of such restriction to its fullest extent, such restriction shall
be enforced to the maximum extent permitted by applicable law. This Separation Agreement and any and all matters arising directly
or indirectly herefrom shall be governed under the laws of the Commonwealth of Massachusetts without reference to choice of law
rules. Employer and Employee consent to the sole jurisdiction of the federal and state courts of Massachusetts. EMPLOYER AND

“Code”) and regulations promulgated thereunder (“Section 409A”). To the extent that any
provision in this Agreement is ambiguous as to its compliance with Section 409A, the provision shall be read in such a manner
so that no payments due under this Agreement shall be subject to an “additional tax” as defined in Section 409A(a)(1)(B)
