SEPARATION
AND GENERAL RELEASE AGREEMENT

 

This
Separation and General Release Agreement (the “Agreement”) is between Barbara White (“White”) and
Corbus Pharmaceuticals, Inc. (“Company”), and memorializes the separation of White’s employment, including the
severance she will receive if she (a) signs and returns this Agreement to the Company on September 17, 2021 (the “Separation
Date”) , (b) does not revoke her acceptance within seven days of her acceptance, and (c) complies with all of the other terms
of this Agreement. By signing and not revoking this Agreement, the parties will be entering into a binding agreement and agreeing to
the terms and conditions in the numbered sections below, including the release of claims in Section 3. White is being provided
a copy of this Agreement in advance as a courtesy but it should not be signed and returned until the Separation Date.

 

1.
Last Day of Employment. White and Company are parties to a Second Amended and Restated Employment Agreement dated as of April
11, 2020 (the “Employment Agreement”). By mutual agreement of the parties, White’s last day of employment with
the Company will be the Separation Date. White will be permitted to take vacation between September 7, 2021 and the Separation Date.
White’s active participation in the Company’s group health insurance plan(s), and any other group benefit plans or programs
in which White participated, if any, will end on the Separation Date. Regardless of whether White enters into this Agreement, White may
have the right to continue the medical, vision and/or dental insurance coverage that she had in effect as of the Separation Date (generally
for up to 18 months) under COBRA and all other payments under Section 11.1 of the Employment Agreement. White will receive COBRA notices
and information about her 401(k) account, in separate letters. White also will receive information about the option to convert group
life insurance coverage to an individual policy.

 

2.
Consideration. If White chooses to sign and return this Agreement within the required time-period, does not revoke her acceptance,
and abides by all of the other terms of this Agreement, the Company agrees to provide White with (a) continuation of her regular base
salary at a rate of $454,400.00, if annualized, for twelve months; (b) provided White timely elects COBRA, Company will reimburse White
for her COBRA premiums for twelve months; and (c) Company will grant Employee an extension of the period of time that Employee may exercise
any vested stock options as of the Separation Date, until June 17, 2023. White acknowledges that the amounts offered above exceed the
amounts White would otherwise be entitled to receive and that the Company would not agree to provide White with this payment without
her general release of claims and other promises in this Agreement. White agrees that this payment constitutes good and valuable consideration
for the general release of claims and other promises in this Agreement.

 

    	 

    	 

    

 

3.
General Release of Claims In exchange for the consideration in Section 2, White (for herself and her heirs, executors,
administrators, beneficiaries, personal representatives and assigns) hereby completely, forever, irrevocably and unconditionally releases

subsidiaries and other affiliated entities, related companies and divisions and each of their respective past, present and future officers,

capacities) and each of their respective employee benefit plans (and such plans’ fiduciaries, agents, administrators and insurers,
individually and in their official capacities), as well as any predecessors, future successors or assigns or estates of any of the foregoing
and any professional employer organization, (all, collectively, the “Released Parties”) from any and all claims, actions,
charges, controversies, causes of action, suits, rights, demands, liabilities, obligations, damages, costs, expenses, attorneys’
fees, damages and obligations of any kind or character whatsoever, that White ever had, now has or may in the future claim to have by

White
expressly acknowledges that this general release of claims includes any and all claims arising up to and including the date White signs
and returns this Agreement which White has or may have against the Released Parties, whether such claims are known or unknown, suspected
or unsuspected, asserted or unasserted, disclosed or undisclosed. By signing this Agreement, White expressly waives any right to assert
that any such claim, demand, obligation or cause of action has, through ignorance or oversight, been omitted from the scope of this release
and White further waives any rights under statute or common law principles that otherwise prohibit the release of unknown claims.

 

This
general release of claims does not apply to, waive or affect: any rights or claims that may arise after the date White signs and
returns this Agreement; any claim for workers’ compensation benefits (but it does apply to, waive and affect claims of discrimination
and/or retaliation on the basis of having made a workers’ 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 White’s rights to any vested
benefits to which White is entitled under the terms of the applicable employee benefit plan (the “Excluded Claims”).
This general release of claims also does not apply to, waive, affect, limit or interfere with White’s preserved rights described
in Section 10 below.

 

4.
Waiver of Claims under ADEA; Time to Consider/Revoke. White acknowledges, understands and agrees that the general release of claims
above includes, but is not limited to, a waiver and release of all claims that White may have under the Age Discrimination in Employment
Act of 1967, as amended (the “ADEA”) arising up to and including the date that White signs and returns this Agreement.
As required by the Older Workers Benefit Protection Act of 1990, White is hereby advised that:

 

	 	●	White
    is not waiving any rights or claims under the ADEA that may arise after the date White signs and returns this Agreement;
	 	●	White
    should consult with an attorney of White’s choice concerning White’s rights and obligations under this Agreement before
    signing this Agreement;
	 	●	White
    should fully consider this Agreement before signing it;
	 	●	nothing
    in this Agreement prevents or precludes White from challenging (or seeking a determination of) the validity of the waiver under the
    ADEA;
	 	●	White
    has at least 21 days days from the date White received this Agreement to consider whether or not White wants to sign it. White may
    use as much or as little of the review period as White wishes before deciding whether or not to sign this Agreement;
	 	●	if
    White does not sign and return this Agreement within the required time period, then the Company’s offer to provide White with
    the severance payment described above will automatically terminate;
	 	●	at
    any time within seven (7) days after signing this Agreement, White may change her mind and revoke her acceptance of this Agreement.
    To be effective, White’s revocation must be in writing and either hand-delivered or sent electronically to the Company within
    the 7-day period;
	 	●	this
    Agreement is not effective or enforceable until (and if) the revocation period has passed without a revocation;
	 	●	if
    White exercises her right to revoke, this Agreement (including, without limitation, the Company’s offer to provide White with
    the severance payment described and White’s release of claims above) will not be enforceable; and
	 	●	if
    White does not revoke her acceptance of this Agreement, the eighth day following the date that White signs this Agreement will be
    the effective date (the “Effective Date”).

5.
No Pending Claims. White represents and warrants that she has no charges, lawsuits, or actions pending in her name against any
of the Released Parties relating to any claim that has been released in this Agreement. White also represents and warrants that she has
not assigned or transferred to any third party any right or claim against any of the Released Parties that White has released in this
Agreement.

 

6.
Covenant not to Sue. Except as provided in Section 10 below, White covenants and agrees that White will not report, institute
or file a charge, lawsuit or action (or encourage, solicit, or voluntarily assist or participate in, the reporting, instituting, filing
or prosecution of a charge, lawsuit or action by a third party) against any of the Released Parties with respect to any claim that has
been released in this Agreement.

 

7.
Cooperation with Investigations/Litigation. White agrees, at the Company’s request, to reasonably cooperate, by providing
truthful information, documents and testimony, in any Company investigation, litigation, arbitration, or regulatory proceeding regarding
events that occurred during White’s employment with the Company. White’s requested cooperation may include, for example,
making herself reasonably available to consult with the Company’s counsel, providing truthful information and documents, and appearing
to give truthful testimony. The Company will, to the extent permitted by applicable law and court rules, reimburse White for reasonable
out-of-pocket expenses that White incurs in providing any requested cooperation, so long as White provides advance written notice to
the Company of White’s request for reimbursement and provides satisfactory documentation of the expenses. Nothing in this section
is intended to, and shall not, preclude or limit White’s preserved rights described in Section 10 below. Moreover, if the parties
mutually agree to have White perform consulting services, Company will pay White at an hourly rate of $275, with further details to be
set forth in a consulting agreement.

 

8.
Non-Disclosure Obligations. White acknowledges her obligation to keep confidential, and to not disclose or use (and agree to keep
confidential and not disclose or use) any and all non-public information concerning the Company that White acquired during the course
of White’s employment (such as non-public information about the Company’s business affairs, prospects and financial condition),
unless such disclosure is made in response to a subpoena, other legal process, valid governmental inquiry or otherwise required by law
or is reasonably necessary to exercise White’s preserved rights under Section 10. White also acknowledges and reaffirms,
and agrees to comply with, White’s obligations under Sections 6, 7, 8, and 9 of the Employment Agreement, which remain in full
force and effect.

9.
Return of Company Documents and Other Property. White agrees that she will immediately disclose to the Company all passwords necessary
or desirable to enable the Company to access all information which White has password-protected on any of its computer equipment, on
its computer network or system, or on any accounts that White used for the Company’s benefit during White’s employment (including,
but not limited to, Slack and cloud). In addition, White confirms that she has returned to the Company any and all Company documents,
materials and information (whether in hardcopy, on electronic media or otherwise) related to Company business and/or containing any non-public
information concerning the Company, as well as all equipment, keys, access cards, credit cards, electronic devices and any other Company
property in White’s possession, custody or control with the exception of computer hardware and software that White will need for
purposes of providing consulting services to the Company after separation. Once consulting services have ended, White confirms that she
will return all computer hardware and software. White also represents and warrants that she has not retained copies of any Company documents,
materials or information (whether in hardcopy, on electronic media or otherwise).

 

10.
Preserved Rights: This Agreement is not intended to, and shall not, in any way prohibit, limit or otherwise interfere with:

 

(a)
White’s protected rights under federal, state or local law to without notice to the Company: (i) communicate or file a charge with
a government regulator; or (ii) participate in an investigation or proceeding conducted by a government regulator; provided, however,
White will not be entitled to any individual relief in connection with such charge, complaint, investigation, or proceeding. For the
avoidance of doubt, nothing herein shall be construed to prevent or limit White from receiving an award paid by a government regulator
for providing information to any governmental authority concerning any suspected violation of law;

 

(b)
White’s protected right to test in any court, under the Older Workers Benefit Protection Act, or like statute or regulation, the
validity of the waiver of rights under ADEA in this Agreement; or

 

(d)
White’s or the Company’s right to enforce the terms of this Agreement and to exercise White’s rights relating to any
other Excluded Claims.

 

11.
No Other Pay or Benefits. White acknowledges and agrees that except as provided herein, White has been paid for all work performed
including, without limitation, all salary/wages, bonuses, overtime, commissions, unused vacation time, and/or any other forms of compensation
due to White up through the Effective Date. White acknowledges and agrees that, except for Company’s obligation to provide the
payment and benefits under Section 2 of this Agreement, White is entitled to no other payments or benefits whatsoever and the Released
Parties have no further obligations to White whatsoever, whether arising out of White’s employment with the Company, the Employment
Agreement, White’s separation from the Company, or otherwise.

 

12.
No Admission. Nothing contained in this Agreement will constitute or be treated as an admission by White, the Company or any of
the other Released Parties of any liability, wrongdoing or violation of law.

Amendments. The Trust Agreement is hereby amended as follows: 
 (a) Section 7.4 of the Trust Agreement is
hereby amended and restated in its entirety to read as follows: 
 Subject to any other requirements of applicable law including
