Executive Summary

Novavax, Inc. (“Novavax”) is a clinical stage biotechnology company, creating novel vaccines to address a broad range of infectious diseases worldwide using advanced proprietary virus-like particle (VLP) technology and manufacturing such vaccines using a proprietary process.

Novavax is developing a monovalent Influenza VLP Vaccine for the pandemic human H1N1 influenza virus (A/California/7/2009), which is commonly referred to as the “swine” flu (the “Product”). The process uses recombinant baculovirus to infect an insect cell culture and express VLPs that contain Hemagglutinin (HA), Neuraminidase (NA), and Matrix (M1) Protein. The proteins self-assemble as they are secreted from the insect cells as particles that resemble influenza virus, but do not contain flu RNA.

The current proposal is for Xcellerex’s commercial production of the bulk drug substance of the Product (the “Bulk Material”) for Novavax for use and sale in Mexico. Xcellerex shall produce the Bulk Material in as many consecutive batches as it deems necessary to produce [* * *] doses of equivalent Bulk Material, but Xcellerex anticipates an initial campaign of an estimated [* * *] consecutive batches. Notwithstanding anything in this Term Sheet to the contrary, in no event shall Xcellerex be required to manufacture more than [* * *] consecutive batches of Bulk Material. Novavax shall order all lots of Bulk Material to be made in continuous consecutive batches for [* * *] doses of equivalent Bulk Material. The parties intend for Xcellerex to be the exclusive contract manufacturer of the Bulk Material for sale in Mexico until February 15, 2010, unless otherwise agreed to by the parties. For other markets where Xcellerex would be the low cost provider of Bulk Material, Novavax agrees to appoint Xcellerex as the co-exclusive supplier of Bulk Material in such market through June 2010, or as mutually agreed, except in territories where Novavax has already granted rights.

Payment and other legal terms are as outlined in Attachment 3.

Proposal Assumptions

The following proposal is for contract services to manufacture commercial material for Novavax and its licensees/partners during the Term. The “Term” shall end on the earlier of: 1) the delivery of [* * *] dose equivalent of Bulk Material; or 2) delivery of Bulk Material from [* * *] batches; or 3) February 15, 2010; or 4) mutual termination or termination as provided in Attachment 3. For avoidance of doubt, in no event shall Xcellerex be required to supply Bulk Material after the expiration of the Term, and in no event shall Novavax be required to pay for Bulk Material delivered after the expiration of the Term.

	A.		Materials and Supplies
	•		Insect cell lines, being delivered to Xcellerex for use in development or manufacturing programs, require acceptance testing to confirm culture purity and identity prior to receipt and use in cGMP manufacturing areas at Xcellerex.
	•		The parties shall agree on the materials to be supplied for manufacture of Product, and whose responsibility it will be to supply the materials. Novavax will supply, at Novavax’s expense, to Xcellerex the raw materials set forth on Attachment 7 and any other materials agreed to by the parties (the “Novavax Materials”), and Xcellerex shall order and supply, at Xcellerex’s expense, the raw materials set forth on Attachment 7 and any other materials agreed to by the parties (the “Xcellerex Materials,” and, together with the Novavax Materials, the “Materials”), in each case for the execution of no more than [* * *] batches under the Work Plan.

Any expense in excess of a party’s agreed upon budget must be approved by the other party and, upon approval, will be split [* * *]% and arrangement will be made to provide Novavax with the appropriate credit to the Per Dose Fee for its portion of the excess expenses. The Novavax Materials will be arranged to arrive at Xcellerex’s facility 10 days in advance of each batch whenever possible, and, where necessary, qualified and released by Novavax quality assurance personnel prior to their expected use in the manufacturing process. In accordance with, and subject to, Attachment 3, Novavax will receive a credit against the Per Dose Fee for Bulk Material upon delivery based on the actual cost for the Novavax Materials supplied by Novavax.

	•		The Bill of Materials for the Work Plan will be completed by Novavax and Xcellerex and will include a designation of which Materials are Novavax Materials and which Materials are Xcellerex Materials. The Parties rely upon Novavax’s information for the completion of the Bill of Materials.
	•		To the extent Novavax Materials are not used by Xcellerex in performance hereunder, the unused Novavax Materials will be handled as set forth in Attachment 3.
	B.		Analytical
	•		The analytical methods required for evaluating Bulk Material quality during the project have yet to be fully specified. A review of the analytical requirements including assay qualifications, and assays required for in-process testing will be required. Attachment 1 contains a list of assays typically performed by Xcellerex.
	C.		Capital Equipment
	•		A list of equipment required by Xcellerex to perform the work in this Term Sheet is included on Attachment 4. Novavax will purchase the equipment so indicated on Attachment 4 and cause it to be shipped to Xcellerex.

Xcellerex shall insure all equipment in its possession, including the equipment to be returned to Novavax. Novavax shall file UCC-1 financing statements on the equipment for bailment.
	•		In the event equipment in addition to that listed on Attachment 4 or already in Xcellerex’s possession is required, the parties shall mutually agree to a resolution regarding such equipment in good faith. Novavax shall not have any additional capital equipment requirements beyond what is indicated in Attachment 4 without mutual consent.
	D.		Volumes
	•		All volumes listed are considered to be working volumes.
	E.		The Manufacturing process to be used by Xcellerex is described in Attachment 2.

Press Release

Novavax and Xcellerex Announce Collaboration to Develop Large-scale
Manufacturing Process for 2009 H1N1 Influenza VLP Vaccine
Partnership will enable rapid, cost-effective, large-scale production
of novel Novavax VLP vaccine utilizing Xcellerex’s FlexFactory ^®
manufacturing solution for Mexico

Rockville, MD and Marlborough, MA — October 21, 2009 — Novavax, Inc. (NASDAQ: NVAX) and Xcellerex, Inc. has entered into a strategic collaboration to accelerate the development of Novavax’s vaccine manufacturing process to commercial scale and begin immediate production of Novavax’s novel 2009 H1N1 influenza vaccine for potential commercial sale. Earlier this week, Novavax launched a two-stage, 4,000-patient clinical study of its H1N1 flu vaccine in Mexico to support registration in that country. The two companies will utilize Novavax’s unique virus-like particle (VLP) vaccine technology to produce initial commercial quantities of H1N1 vaccine with Xcellerex’s FlexFactory biomanufacturing platform. Xcellerex will provide development expertise and product manufacturing in exchange for manufacturing supply fees from Novavax.

“We are pleased to apply our state-of-the-art FlexFactory manufacturing technology to enable the rapid, commercial-scale production of H1N1 flu vaccine by Novavax. Our technology offers Novavax a cost-effective and flexible manufacturing solution for this public health crisis by achieving full commercial-scale production of VLP-based vaccines much more rapidly than traditional vaccine production methods,” stated Joseph Zakrzewski, Xcellerex’s President and Chief Executive Officer.

“This strategic partnership represents a major step forward for Novavax and will allow us to increase the scale of our VLP vaccine manufacturing process and expand capacity to satisfy potential demand for our H1N1 VLP vaccine in Mexico. This alliance will also enable us to establish commercial-scale production capabilities for our VLP-based seasonal influenza vaccine program and significantly advance our timeline for full scale manufacturing,” said Rahul Singhvi, Novavax’s President and Chief Executive Officer.

About VLPs

Virus-like particles (VLPs) mimic the external structure of viruses but lack the live genetic material that causes viral replication and infection. VLPs can be designed quickly to match individual viral strains and be produced efficiently using portable cell-culture technology. Novavax VLP-based vaccine candidates are produced more rapidly than egg-based vaccines by using proprietary, portable, recombinant cell-culture technology.

About FlexFactory

Xcellerex’s FlexFactory is an innovative, portable manufacturing platform, based on the innovative application of (1) single-use technologies; (2) controlled environmental modules (CEMs); and (3) advanced and proven process automation including electronic batch records. The FlexFactory effectively eliminates clean and steam-in-place and clean room infrastructure, greatly simplifies facility design, reducing manufacturing footprint and capital investment, and creates breakthrough gains in operating efficiency, flexibility and environmental friendliness.

About Novavax

Novavax, Inc. is a clinical-stage biotechnology company, creating novel vaccines to address a broad range of infectious diseases worldwide, including H1N1, using advanced proprietary virus-like-particle (VLP) technology. The company produces potent VLP -based, recombinant vaccines utilizing new and efficient manufacturing approaches.
