ITEM 2. PROPERTIES
 
Our corporate executive offices, laboratory and other spaces are in located in leased facilities in Houston, Texas. In March 2018, we entered into a Lease Agreement (the “Lease”) which we use for corporate office space and headquarters. The term of the Lease began in August 2018 and will continue for an initial term of 66 months, which may be renewed for an additional 5 years. We are required to remit base monthly rent which will increase at an average approximate rate of 3% each year. We are also required to pay additional rent in the form of our pro-rata share of certain specified operating expenses of the landlord.
 
In August 2019, we entered into an Amended Lease Agreement (the "Lab Lease") for our lab space. The term of the Lab Lease began in September 2019 and will continue for an initial term of 35 months, with no further right or option to renew. We are required to remit base monthly rent which will increase at an average approximate rate of 3% each year. The Lab Lease is classified as an operating lease. In August 2019, we entered into a sublease with Houston Pharmaceuticals, Inc. (HPI), which is affiliated with Dr. Priebe. We granted HPI access to all of the Lab Lease space and HPI has agreed to pay us 50% of the rent payable under the Lab Lease less 50% of any benefits from any sublease or other lab service agreement we may receive from the Lab Lease. Although HPI has access to the space, it is the intent of the parties that they equally share the Lab Lease space for research purposes. We believe our facilities, as expanded, will be sufficient to meet our current needs and that suitable space will be available as and when needed. We do not own any real property.
