On July 29, 2013, the Company entered into a modification agreement with the U.S. Naval Medical Logistics Command to terminate their existing agreement dated September 29, 2012 related to dengue fever and malaria vaccine development efforts at the NMRC. The termination agreement  terminates the existing agreement pursuant to the Navy’s right of termination for convenience effective July 30, 2013, and was the result of a request by the Company in light of the Company’s efforts to reduce its ongoing business operations. The Company has received approximately $1.4 million of the $3.5 million that the Company originally anticipated receiving over a three year period pursuant to the September 29, 2012 agreement.
