Commitments and Contingencies

Rental and lease expense was $4.4 million and $4.2 million for the years ended December 31, 2018 and 2017, respectively. The rental and lease expense primarily relates to compressor rentals and the lease of our office space in Houston, Texas. During 2016 the Company entered into a four-year sub-lease agreement for office space in Houston, Texas. The operating lease commenced on January 1, 2017. Additionally, on August 31, 2017 we amended the sub-lease agreement for additional office space. As of December 31, 2018, the minimum contractual obligations were approximately $1.5 million in the aggregate.

Our minimum annual obligations under non-cancelable operating lease commitments are $2.3 million for 2019, $0.8 million for 2020, $0.3 million for 2021 and approximately $3.5 million in the aggregate.

We have gas transportation and processing minimum obligations amounting to $8.3 million for 2019, $12.6 million for 2020, $5.6 million for 2021, $4.0 million for 2022, $2.8 million for 2023 and $35.9 million in the aggregate.

Additionally we have drilling commitments amounting to $2.2 million for 2019 and executive severance agreements amounting to $0.6 million for 2019.

In the ordinary course of business, we are party to various legal actions, which arise primarily from our activities as operator of oil and natural gas wells. In management's opinion, the outcome of any such currently pending legal actions will not have a material adverse effect on our financial position or results of operations.
