On July 13, 2015, the Company entered into a Sales Agreement with Cowen and Company, LLC (“Cowen”) to sell, from time to time, shares of the Company’s common stock having an aggregate sales price of up to $40,000,000 through an “at the market offering” program under which Cowen will act as sales agent. Through August 7, 2015, the Company has generated approximately $7.7 million in net proceeds under this program.

On July 22, 2015, the Company entered into an amendment to its facility lease. The lease amendment provides an additional 13,843 square feet of leased space at the Company’s current facility in Cambridge, Massachusetts, with a termination date of June 30, 2019, which is co-terminous with the Company’s existing lease. As a result of this amendment, the Company has additional lease payments totaling approximately $2.2 million through 2019. In addition, under the terms of the amendment, the landlord will provide the Company with an aggregate leasehold improvement allowance of up to approximately $0.5 million.
