Lease Amendments

In March 2015, the Company provided notice to the landlord of its intent to exercise the two year lease extension option for office and laboratory space at the Company’s headquarters in Lexington, MA.  The lease term will now extend to December 31, 2017.  The final terms of the lease extension period are still being finalized between the parties.

In March 2015, the Company entered into an amendment to extend the term of an office space lease. The lease amendment extends the lease term to December 31, 2017 and the annual rent for the additional year is approximately $300,000.
