U.S. Government Agreement and Collaboration	Note 5 – U.S. Government Agreement and Collaboration *HHS BARDA Contract Award for Recombinant Influenza Vaccines* In February 2011, the Company was awarded a contract from HHS BARDA valued at $97 million for the 36-month base-period, with an HHS BARDA option for an additional period of 24 months valued at $82 million, for a total contract value of up to $179 million. The HHS BARDA contract award provides significant funding for the Company’s continued ongoing clinical development and product scale-up of both its seasonal and pandemic influenza vaccine candidates. This is a cost-plus-fixed-fee contract in which HHS BARDA will reimburse the Company for direct contract costs incurred plus allowable indirect costs and a fee earned in the further development of its seasonal and pandemic (H5N1) influenza vaccines.

These indirect rates are subject to audit by HHS BARDA on an annual basis.

During the three months ended March 31, 2012, the Company recognized revenue of approximately $4.5 million under this contract.

The Company recently decided to conduct its Phase II dose-ranging clinical trial of its trivalent and quadrivalent seasonal influenza vaccine candidates (the “205 Trial”) under its existing U.S. investigational new drug application (“IND”) for its trivalent seasonal influenza vaccine candidate (“Trivalent IND”) as opposed to waiting to conduct the 205 Trial under a new IND for its quadrivalent vaccine candidate (“Quadrivalent IND”), which it plans to submit to the FDA in the second half of 2012. Based on discussions between HHS BARDA and the Company, because the 205 Trial includes its quadrivalent seasonal influenza vaccine candidate, the outside clinical trial costs for the 205 Trial will only be submitted for reimbursement to HHS BARDA and recorded as revenue by the Company after it submits the 205 Trial data to its Quadrivalent IND, which is also expected to occur in the second half of 2012. Until then, the Company will record the outside clinical trial costs of the 205 Trial as cost of contract revenue. The financial impact of this delay in revenue recognition is based on the outside clinical trial costs of the 205 Trial that are expected to total approximately $3.1 million, of which $1.7 million was incurred through March 31, 2012. *License Agreement with LG Life Sciences, Ltd.* In February 2011, the Company entered into a license agreement with LG Life Sciences, Ltd.

At its own cost, LGLS is responsible for funding its clinical development of the influenza VLP vaccines and completing a manufacturing facility in South Korea. The term of the license agreement is expected to terminate in 2027.
