Agreements for Office Space

In August 2013, the Company entered into a sublease agreement with a related party (see Note 11) for office space which is its corporate headquarters.

The Company further amended the terms of this sublease agreement in December 2014, August 2015, February 2016, October 2016 and July 2017 to increase the square footage of the space being subleased and/or agree to new sublease terms. The August 2015 amendment extended the term of the lease to November 2019.
