WHEREAS, Employer and Employee entered into that certain Amended and Restated Employment Agreement, dated as of July 20, 2009, as amended (the “Employment Agreement”); and

WHEREAS, Employer and Employee will terminate their employment relationship effective as of April 19, 2010 and pursuant to a letter (the “Termination Letter”) to Employee from Stanley C. Erck, President and Chief Executive Officer of the Company, dated April 19, 2010 (the “Termination Date”).

NOW, THEREFORE, in consideration of the premises and the mutual promises set forth herein, Employee agrees as follows:

1.          Consideration. Employee is entering into this Release Agreement in consideration of Employer’s offer of separation pay (in the gross amount of $681,831), as well as other good and valuable consideration including the transfer of ownership of Employee’s Apple laptop computer and mobile phone. Employee hereby accepts the severance offer, and agrees to be bound by this Release Agreement.

2.          General Release of Claims. For himself and his heirs, executors, administrators, assigns, agents and beneficiaries, if any, Employee does hereby agree to execute and be bound by the following general release of Claims (“Release”):

I, Rahul Singhvi, waive, release, and forever discharge Employer (as defined below) of and from any and all Claims (as defined below) arising from the beginning of time up to and including the date of this Release. I agree not to file a lawsuit or arbitration to assert any such Claim. Further, I agree that should any other person, organization or entity file a lawsuit or arbitration to assert any such Claim, I will not seek or accept any personal relief in such action.

/s/ RS [Initial]

Notwithstanding any other provision of this Release, the following are not barred by the Release: (i) Claims relating to the validity of this Release Agreement; (ii) Claims by either party to enforce this Release Agreement; and (iii) Claims which legally may not be waived. In addition, this Release will not operate to limit or bar Employee’s right to file an administrative charge of discrimination with the Equal Employment Opportunity Commission (EEOC) and to participate in an investigation by the EEOC, although the Release does bar Employee’s right to recover any personal relief if Employee or anyone on his behalf seeks to file a subsequent lawsuit or arbitration on the same basis as the charge of discrimination.

For the purpose of this Release, “Claims” include without limitation all actions, rights or demands of any kind that Employee now has, or may have or claim to have in the future. More specifically, Claims include rights, causes of action, damages, penalties, losses, attorneys’ fees, costs, expenses, obligations, agreements, judgments and all other liabilities of any kind or description whatsoever, either in law or in equity, whether known or unknown, suspected or unsuspected. The nature of Claims covered by this Release includes, without limitation, all actions or demands in any way based on my employment with Employer, the terms and conditions of such employment or my separation from employment. More specifically, all of the following are among the types of Claims which are waived and barred by this Release as and to the extent allowable under applicable law:

The foregoing description of Claims is intended to be illustrative rather than exhaustive.

For the purpose of this Release, “Employer” includes without limitation Novavax, Inc. and its respective past, present and future parents, owners, affiliates, subsidiaries, divisions, predecessors, successors, assigns, employee benefit plans and trusts, if any.
