AMENDED AND RESTATED
EMPLOYMENT AGREEMENT

                This Amended and Restated Employment Agreement (this “Agreement”) is dated as of August 2, 2007, originally effective November 9, 2005, between Novavax, Inc., a Delaware corporation having its principal office at 9920 Belward Campus Drive, Rockville, MD 20850, and Raymond J. Hage, Jr., an individual with a mailing address of 115 Applegate Drive, West Chester 19355 (“Executive”). This Agreement is being amended and restated to provide for certain required changes.

                The Company and Executive hereby agree as follows:

                1.             Employment.  The Company hereby employs Executive and Executive hereby accepts employment as Senior Vice President of Commercial Operations upon the terms and conditions hereinafter set forth. As used throughout this Agreement, “Company” shall mean and include any and all of its present and future subsidiaries and any and all subsidiaries of a subsidiary. Executive warrants and represents that he is free to enter into and perform this Agreement and is not subject to any employment, confidentiality, non-competition or other agreement which prohibits, restricts, or would be breached by either his acceptance or his performance of this Agreement.

                2.             Duties.  During the Term (as hereinafter defined), Executive shall devote his full business time to the performance of services as Senior Vice President of Commercial Operations of Novavax, Inc., performing such services, assuming such responsibilities and exercising such authority as are set forth in the Bylaws of the Company for such offices and assuming such other duties and responsibilities as prescribed by the President and CEO and Board of Directors.

Executive agrees to perform his services faithfully and to the best of his ability and to carry out the policies and directives of the Company. Notwithstanding the foregoing, it shall not be a violation of this Agreement for the Executive to serve as a director of any company whose products do not compete with those of the Company and to serve as a director, trustee, officer, or consultant to a charitable or non-profit entity; provided that such service does not adversely affect Executive’s ability to perform his obligations hereunder. Executive agrees to take no action which is in bad faith and prejudicial to the interests of the Company during his employment hereunder. Notwithstanding the location where Executive shall be based, as set forth in this Agreement, he also may be required from time to time to perform duties hereunder for reasonably short periods of time outside of said area.

                3.             Term.  The term of this Agreement shall be for the period beginning on August 10, 2005 and continuing until September 1, 2008, unless earlier terminated pursuant to Section 7 hereof (the “Term”) and shall be renewable on the terms set forth herein upon agreement of the Company and Executive of the term of such renewal and the initial base compensation applicable to the renewal term.

                11.           Non-Competition Covenant.  As the Executive has been granted options to purchase stock in the Company and as such has a financial interest in the success of the Company’s business and as Executive recognizes that the Company would be substantially injured by Executive competing with the Company, Executive agrees and warrants that within the United States, he will not, unless acting with the Company’s express prior written consent, directly or indirectly, while an employee of the Company and during the Non-Competition Period, as defined below, own, operate, join, control, participate in, or be connected as an officer, director, employee, partner, stockholder, consultant or otherwise, with any business or entity which competes with the business of the Company (or its successors or assigns) as such business is now constituted or as it may be constituted at any time during the Term of this Agreement; provided, however, that Executive may own, and exercise rights with respect to, less than one percent of the equity of a publicly traded company. The “Non-Competition Period” shall be a period of six months following termination of employment.

                Executive and the Company are of the belief that the period of time and the area herein specified are reasonable in view of the nature of the business in which the Company is engaged and proposes to engage, the state of its business development and Executive’s knowledge of this business; however, if such period or such area should be adjudged unreasonable in any judicial proceeding, then the period of time shall be reduced by such number of months or such area shall be reduced by elimination of such portion of such area, or both, as are deemed unreasonable, so that this covenant may be enforced in such area and during such period of time as is adjudged to be reasonable.

Executive also acknowledges that the Non-Disclosure and Non-Competition Agreement he signed upon becoming an employee remains in full force and effect despite the changes in his employment status with the Company.

                16.           Equitable Relief.  Executive recognizes and agrees that the Company’s remedy at law for any breach of the provisions of Sections 9, 10, 11 or 12 hereof would be inadequate, and he agrees that for breach of such provisions, the Company shall, in addition to such other remedies as may be available to it at law or in equity or as provided in this Agreement, be entitled to injunctive relief and to enforce its rights by an action for specific performance. Should Executive engage in any activities prohibited by this Agreement, he agrees to pay over to the Company all compensation, remuneration or monies or property of any sort received in connection with such activities; such payment shall not impair any rights or remedies of the Company or obligations or liabilities of Executive which such parties may have under this Agreement or applicable law.

                17.           Amendments.  This Agreement may not be amended, nor shall any change, waiver, modification, consent or discharge be effected except by written instrument executed by the Company and Executive.

Executive agrees that the restrictions set forth in Sections 11 and 12 above (including, but not limited to, the geographical scope and time period of restrictions) are fair and reasonable and are reasonably required for the protection of the interests of the Company and its affiliates. In the event that any provision of Section 11 or 12 relating to time period and/or areas of restriction shall be declared by a court of competent jurisdiction to exceed the maximum time period or areas such court deems reasonable and enforceable, said time period and/or areas of restriction shall be deemed to become and thereafter be the maximum time period and/or areas which such court deems reasonable and enforceable.
