Exhibit 10.1

NOVAVAX, INC.

AMENDED AND RESTATED

CHANGE IN CONTROL SEVERANCE BENEFIT PLAN

Section 1. Introduction.

     The Novavax, Inc. Change in Control Severance Benefit Plan (“Plan”) was originally approved by the Board of Directors (the “Board”) of Novavax, Inc. (the “Company”) and became effective on August 10, 2005, and was subsequently amended and restated on July 26, 2006. On December 22, 2008, the Board approved an amendment and restatement of the Plan as set forth herein, effective January 1, 2008 (“Effective Date”). The purpose of the Plan is to provide severance benefits to certain eligible employees of the Company in the event of their termination of employment in connection with a Change in Control (as defined herein). This Plan document also is the Summary Plan Description for the Plan. The amendment and restatement of the Plan is designed to ensure that the severance benefits payable under the plan are exempt from the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Code”).

     Certain capitalized terms used in the Plan are defined in Section 6.

Section 2. Eligibility For Benefits.

     (a) General Rules.

          (i) Subject to the requirements set forth in this Section 2, the Company shall grant benefits under the Plan to Eligible Employees. “Eligible Employees” include those employees of the Company who are approved by the Board in its sole and absolute discretion and designated as participants in this Plan. Employees who have been selected to participate by the Board shall be listed on Exhibit A to this Plan. At any time the Board may select additional employees to participate in the Plan, but no employee or other service provider of the Company who has not been specifically approved by the Board shall be eligible for benefits hereunder.

          (ii) An Eligible Employee shall be eligible for benefits under this Plan if the Eligible Employee’s employment with the Company terminates due to an Involuntary Termination without Cause for a reason other than the Eligible Employee’s death or Disability, or as a result of a Constructive Termination, which in either case occurs: (x) during the period not to exceed twenty-four (24) months after the effective date of a Change in Control (where the number of months for a particular Eligible Employee is equal to the period for which he or she is receiving severance as specified on Exhibit A), or (y) before the effective date of a Change in Control, but after the first date on which the Board and/or senior management of the Company has entered into formal negotiations with a potential acquirer that results in the consummation of a Change in Control (provided, however, that in no event shall a termination of employment occurring more than one (1) year before the effective date of a Change in Control be covered by this Plan).

     (b) Other Requirements.

          (i) In order to be eligible to receive benefits under the Plan, an Eligible Employee must execute a general waiver and release of all legal claims against the Company and its Affiliates and their representatives on a form satisfactory to the Company.

          (ii) Any Change in Control that triggers the payment of benefits under this Plan must occur during the term of this Plan as specified in Section 5(b).

     (c) Exceptions. Notwithstanding the foregoing:

          (i) An Eligible Employee who is eligible for Change in Control severance benefits under any individually negotiated employment contract or agreement between the Eligible Employee and the Company shall be deemed to have elected to receive severance benefits under this Plan and shall not be eligible for any severance benefits under such other employment contract or agreement (unless expressly provided otherwise by the Board in a manner that does not violate the requirements of Section 409A of the Code).

          (ii) An Eligible Employee whose employment is terminated by the Company for Cause at any time, who terminates employment voluntarily for a reason other than a Constructive Termination (including termination of employment because of the Eligible Employee’s death or Disability), whose employment terminates for any reason, whether initiated by the Eligible Employee or the Company, more than twenty-four (24) months after the effective date of the Change in Control (or, if less, the number of months designated by the Board on Exhibit A for which the Eligible Employee is entitled to severance), or before the beginning of formal negotiations with a potential acquirer of the Company’s business or more than one year before the effective date of Change in Control (even if formal negotiations with a potential acquirer have begun), shall not be eligible to receive Change in Control severance benefits under this Plan (and the Eligible Employee’s participation in this Plan shall terminate at that time).

Section 3. Amount and Type Of Benefits; Limitations and Exceptions.

     Benefits payable under the Plan are as follows and are subject to the following limitations and exceptions:

     (a) The Company, in its sole discretion, may grant to an Eligible Employee, and his or her dependents and beneficiaries (if applicable) any of the following benefits or combination thereof:

          (ii) Up to twenty-four (24) months of any medical, dental, vision and hospitalization insurance benefits, beginning immediately following the Termination Date, to the extent an Eligible Employee elects coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) and remains eligible for such COBRA coverage; such benefits to be provided on terms and conditions no less favorable to the Eligible Employee than those in effect immediately prior to the Termination Date;

          (iii) A period of up to one (1) year, or the remaining time of the term of grant, if shorter, after his or her Termination Date during which to exercise otherwise vested exercisable, and unexpired stock options.

     (d) Parachute Payments.

          (i) Notwithstanding the above, if any payment or benefit that an Eligible Employee would receive under this Plan, when combined with any other payment or benefit he or she receives that is contingent upon a Change in Control (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (“Excise Tax”), then such Payment shall be either (x) the full amount of such Payment or (y) such lesser amount (with Payments being reduced in the order and priority established by the Board) as would result in no portion of the Payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local employment taxes, income taxes, and the Excise Tax results in the Eligible Employee’s receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. The Eligible Employee shall be solely responsible for the payment of all personal tax liability that is incurred as a result of the payments and benefits received under this Plan, and Participant will not be reimbursed by the Company for any such payments.

          (ii) The Company shall attempt to cause its accountants to make all of the determinations required to be made under Section 3(d)(i), or, in the event the Company’s accountants will not perform such service, the Company may select another professional services firm to perform the calculations. The Company shall request that the accountants or firm provide detailed supporting calculations both to the Company and Eligible Employee prior to the Change in Control if administratively feasible or subsequent to the Change in Control if events occur that result in parachute payments to the Eligible Employee at that time. For purposes of making the calculations required by Section 3(d), the accountants or firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith determinations concerning the application of the Code. The Company and Eligible Employee shall furnish to the accountants or firm such information and documents as the accountants or firm may reasonably request in order to make a determination under this Section 3(d). The Company shall bear all costs the accountants or firm may reasonably incur in connection with any calculations contemplated by Section 3(d). Any such determination by the Company’s accountants or other firm shall be binding upon the Company and Eligible Employee, and the Company shall have no liability to Eligible Employees for the determinations of its accountants or other firm.

     (e) Any provisions contained in the Company’s stock option or equity plans, or contained in an Eligible Employee’s individual stock option agreement with the Company, regarding the accelerated vesting or exercisability of stock options or awards upon a Change in Control shall continue to apply and may be supplemented by, but shall not be superseded by, the terms of this Plan.

Section 4. Time Of Payment And Form Of Benefit; Indebtedness.

     (a) Cash benefits under this Plan as described in the attached Benefit Schedule, less applicable tax withholdings, shall be paid to an Eligible Employee in a lump sum. The Company reserves the right to determine the timing of such payments, provided, however, that all payments under this Plan shall be completed within sixty (60) days after an Eligible Employee’s Termination Date or, in the case where an Eligible Employee’s Termination Date precedes a Change in Control, sixty (60) days after the effective date of the Change in Control (subject to the provisions requiring later payment set forth in Section 4(c) below). Notwithstanding the above, no payment shall be made under this Plan prior to the last day of any waiting period or revocation period as required by applicable law in order for the general waiver and release of legal claims required by Section 2(b)(i) of this Plan to be effective; provided, however, that in any event such payment is made no later than two and one-half (2-1/2) months following the calendar year in which the later of the Termination Date or effective date of the Change in Control occurs.

     (b) If an Eligible Employee is indebted to the Company at his or her payment date, the Company reserves the right to offset any payments under the Plan by the amount of such indebtedness.

Section 5. Right To Interpret Plan; Amend And Terminate; Binding Nature Of Plan.

     (a) Exclusive Discretion. The Plan Administrator (defined below) shall have the exclusive discretion and authority to establish rules, forms, and procedures for the administration of the Plan, and to construe and interpret the Plan and to decide any and all questions of fact, interpretation, definition, computation or administration arising in connection with the operation of the Plan, including, but not limited to, the eligibility to participate in the Plan and the amount of benefits paid under the Plan. The rules, interpretations, computations and other actions of the Plan Administrator shall be binding and conclusive on all persons.

     (b) Term Of Plan; Amendment Or Termination.

          (i) The Board reserves the right to amend or modify the terms of the Plan or the benefits provided hereunder at any time, provided, however, that any such amendment or modification that diminishes or otherwise adversely affects the rights or benefits of an Eligible Employee under the Plan shall only become effective upon the written consent of any such affected Eligible Employee. The Board may terminate the Plan at any time with the written consent of the Eligible Employees, or may terminate a particular Eligible Employee’s participation in the Plan or entitlement to benefits with the written consent of such Eligible Employee. Notwithstanding the above, the Plan may be terminated by the Board in its discretion, without the consent of any Eligible Employee, at any time after the date that is twelve (12) months after a Change in Control event (or twenty-four months in the case of the Chief Executive Officer), provided that all unpaid severance benefits related to such Change in Control

have been paid to Eligible Employees whose Termination Date occurred prior to the termination of the Plan.

          (ii) Eligible Employees shall have the right to be promptly notified that any action amending or terminating the Plan has been taken.

     (c) Binding Effect On Successor To Company. This Plan shall be binding upon any successor or assignee, whether direct or indirect, by purchase, merger, consolidation or otherwise, to all or substantially all the business or assets of the Company, or upon any successor to the Company as the result of a Change in Control, and any such successor or assignee shall be required to perform the Company’s obligations under the Plan, in the same manner and to the same extent that the Company would be required to perform if no such succession or assignment or Change in Control had taken place. In such event, the term “Company,” as used in the Plan, shall mean the Company as hereinafter defined and any successor or assignee as described above which by reason hereof becomes bound by the terms and provisions of this Plan, and the term “Board” shall refer to the Board of Directors of any such surviving or continuing entity.

Section 12. Statement Of ERISA Rights.

     Participants in this Plan (which is a welfare benefit plan sponsored by Novavax, Inc.) are entitled to certain rights and protections under ERISA. If you are an Eligible Employee, you are considered a participant in the Plan and, under ERISA, you are entitled to:

     Receive Information About Your Plan and Benefits

     (a) Examine, without charge, at the Plan Administrator’s office and at other specified locations, such as worksites, all documents governing the Plan and a copy of the latest annual report (Form 5500 Series) filed by the Plan, if required, with the U.S. Department of Labor and available at the Public Disclosure Room of the Employee Benefits Security Administration;

     (b) Obtain, upon written request to the Plan Administrator, copies of documents governing the operation of the Plan and copies of the latest annual report (Form 5500 Series), if required, and an updated (as necessary) Summary Plan Description. The Administrator may make a reasonable charge for the copies; and

     (c) Receive a summary of the Plan’s annual financial report. The Plan Administrator is required by law to furnish each participant with a copy of this summary annual report.

Prudent Actions by Plan Fiduciaries

     In addition to creating rights for Plan participants, ERISA imposes duties upon the people who are responsible for the operation of the employee benefit plan. The people who operate the Plan, called “fiduciaries” of the Plan, have a duty to do so prudently and in the interest of you and other Plan participants and beneficiaries. No one, including your employer, your union or any other person, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a Plan benefit or exercising your rights under ERISA.

Enforce Your Rights

     If your claim for a Plan benefit is denied or ignored, in whole or in part, you have a right to know why this was done, to obtain copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules.

     Under ERISA, there are steps you can take to enforce the above rights. For instance, if you request a copy of Plan documents or the latest annual report from the Plan (note: the Plan currently is not subject to the requirement of filing such an annual report) and do not receive them within 30 days, you may file suit in a Federal court. In such a case, the court may require the Plan Administrator to provide the materials and pay you up to $110 a day until you receive the materials, unless the materials were not sent because of reasons beyond the control of the Administrator.

     If you have a claim for benefits which is denied or ignored, in whole or in part, you may file suit in a state or Federal court. In addition, if you disagree with the Plan’s decision or lack

thereof concerning the qualified status of a domestic relations order or a medical child support order, you may file suit in Federal court.

     If it should happen that Plan fiduciaries misuse the Plan’s money, or if you are discriminated against for asserting your rights, you may seek assistance from the U.S. Department of Labor, or you may file suit in a Federal court. The court will decide who should pay court costs and legal fees. If you are successful, the court may order the person you have sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees, for example, if it finds your claim is frivolous.

Assistance with Your Questions

     If you have any questions about the Plan, you should contact the Plan Administrator. If you have any questions about this statement or about your rights under ERISA, or if you need assistance in obtaining documents from the Plan Administrator, you should contact the nearest office of the Employee Benefits Security Administration, U.S. Department of Labor, listed in your telephone directory or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue N.W., Washington, D.C. 20210. You may also obtain certain publications about your rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

For a period not to exceed twenty-four (24) months (the “Continuation Period”), as determined by the Company, the Company shall, at its expense, continue on behalf of the Eligible Employee and the Employee’s dependents and beneficiaries the following insurance benefits: any medical, dental, vision and hospitalization benefits provided to the Eligible Employee immediately prior to the Termination Date; provided, however, that the Company’s obligation to provide continuation coverage shall arise under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), and shall apply only if the Eligible Employee timely elects COBRA coverage and the Eligible Employee and his or her dependents are otherwise eligible for benefits under COBRA. Accordingly, in the case of an Eligible Employee whose Termination Date precedes the effective date of the Change in Control and who did not timely elect COBRA coverage prior to becoming eligible for benefits under this Plan, no reimbursements or payments for health care continuation will be made by the Company under this Section (unless such Eligible Employee has received COBRA benefits following their Termination Date, and/or is currently receiving those benefits at the time of a Change in Control, in which case the Company will reimburse any past COBRA premium costs and will pay for future coverage) in accordance with the terms of this Section for the period specified above.

     The coverage and benefits (including deductibles and costs) provided hereunder during the Continuation Period shall be no less favorable to the Eligible Employee and the Employee’s dependents and beneficiaries, than the coverage and benefits made available immediately prior to the Termination Date. The Company’s obligation hereunder with respect to the foregoing benefits shall be limited to the extent that the Eligible Employee obtains any such benefits pursuant to a subsequent employer’s benefit plans, in which case the Company may reduce the coverage of any benefits it is required to provide the Eligible Employee hereunder as long as the aggregate coverages and benefits of the combined benefit plans are no less favorable to the Employee than the coverages and benefits required to be provided hereunder.

4. With respect to any stock option held by an Eligible Employee that is outstanding under any Company stock option or equity incentive plan at the time the Employee becomes eligible for benefits under this Plan (either at the Termination Date or upon the Change in Control if termination has already occurred), the Company agrees that, at the time of the Termination Date or Change in Control, as applicable the Eligible Employee shall be given a period of one (1) year following his or her Termination Date in which to exercise the options to the extent such options are otherwise vested and exercisable as of the Termination Date under the terms of the applicable stock option agreement(s) and plan(s), but provided that no exercise may occur later than the expiration date of the option as set forth is the applicable option agreement or plan. Notwithstanding the above, this Section 4 shall not apply to stock options that have expired (including after any post-termination exercise period) at the time an Eligible Employee becomes eligible for benefits under the Plan. The foregoing agreement shall not apply to any stock options that already have a one year or greater post-termination exercise period. The Eligible Employee acknowledges that, by agreeing to an offer to extend the exercise period in this manner, his or her stock options may be converted from an incentive stock option into a non-statutory stock option.

5. This Section 5 applies only to stock options issued to an Eligible Employee under any Company stock option or equity incentive plan after the effective date of the amended and restated version of this Plan (“New Option Grants”). With respect to any New Option Grants that are outstanding at the time an Eligible Employee becomes eligible for benefits under this Plan, the vesting and exercisability of such New Option Grants shall be accelerated in full, and the Option shall be considered 100% vested, as of the date the Eligible Employee becomes entitled to benefits hereunder. This provision shall not apply to any stock option that contains a more favorable vesting provision under the applicable stock option agreement or any individually negotiated agreement (such as 100% “single trigger” vesting upon a Change in Control). It is possible that an Eligible Employee may terminate employment, and his or her stock options may have expired (without being exercised) before a subsequent Change in Control transaction (although the Employee may still be entitled to benefits under this Plan in that instance). In that case, no accelerated vesting shall occur under this provision as to an already expired stock option.
