Note 5 – Lease

The Company leases 14,782 square feet of office and laboratory space located in Austin, Texas. On April  20, 2018, the Company entered into an amendment to its existing operating lease which extended the lease term from May 31, 2018 to May 31, 2021. The annual base rent in the first year of the lease extension was $184,775 and increases by $7,391 in each succeeding year of the lease extension. In addition, the Company is required to pay its proportionate share of operating costs for the building under this triple net lease. The lease does not contain renewal or termination options.

For purposes of calculating the right of use asset and lease liability included in the Company's financial statements, the Company estimated its incremental borrowing rate at 8% per annum.

In September 2019, the Company entered into a sublease with CE+T Energy pursuant to which the Company subleases approximately seventy-five (75%) percent of its Austin, Texas facility to CE+T Energy. Under the sublease, CE+T Energy is obligated to make monthly payments equal to 75% of all sums due under the master lease and 100% of any maintenance and repair costs related to the subleased premises. The sublease replaced a temporary agreement between the Company and CE+T Energy, effective in July 2019, that contained similar payment obligations by CE+T Energy for utilization of the subleased premises. Consistent with the master lease, the sublease terminates on May 31, 2021. During the three months ended March 31, 2021, CE+T Energy made payments of $53,293 to the Company related to the subleased premises. The payments included CE+T Energy’s share of rent as well as its proportionate share of operating costs for the building under the master lease. The Company recognized these payments as a reduction in general and administrative expenses.

Future minimum payments under the lease, as amended, are as follows:

For the three months ended March 31, 2021 and 2020, operating cash flows for lease payments totaled $49,889 and $48,041, respectively. For both the three months ended March 31, 2021 and 2020, operating lease cost, recognized on a straight-line basis, totaled $48,488. At March 31, 2021, the remaining lease term was 2 months.

In March 2021, the Company entered into a lease agreement for 4,070 square feet of office and laboratory space located in Austin, Texas. The commencement of the lease is expected to occur on June 1, 2021 and the term of the lease is 63 months. The actual base rent in the first year of the lease is $56,471 and is net of $18,824 in abated rent over the first three months of the lease term. The annual base rent in the second year of the lease is $77,330 and increases by $2,035 in each succeeding year of the lease. In addition, the Company is required to pay its proportionate share of operating costs for the building under this triple net lease. The lease contains a 5-year fair market renewal option. It does not contain a termination option. The Company will recognize a right of use asset and lease liability for this lease upon lease commencement.
