Item 1B. Unresolved Staff Comments.
Item 2. Properties.
Our corporate headquarters are located in Skokie, Illinois, where we lease approximately 12,000 square feet of office and laboratory space. The lease term for our office and laboratory space in Skokie, Illinois commenced in March 2012 for a lease term of three years. In March 2014, we amended the lease agreement to extend the term for an additional six years, which expires in 2021. In May 2016, we amended the lease agreement to include additional space to be used primarily for administrative functions.
We believe that our existing facilities are adequate for our current needs and have sufficient laboratory space to house additional scientists as we grow. When our lease expires, we may exercise our renewal options or look for additional or alternate space for our operations. We believe that suitable additional or alternative space will be available in the future on commercially reasonable terms.
Item 3. Legal Proceedings.
From time to time, we may be subject to legal proceedings. We are not currently a party to or aware of any proceedings that we believe will have, individually or in the aggregate, a material adverse effect on our business, financial condition or results of operations.
Item 4. Mine Safety Disclosures.
