Restricted stock awards represent a right to receive shares of common stock at a future date determined in accordance with the participant’s award agreement. There is no exercise price and no monetary payment required for receipt of restricted stock awards or the shares issued in settlement of the award. Instead, consideration is furnished in the form of the participant’s services to the Company. Compensation cost for these awards is based on the fair value of the shares of common stock on the date of grant and recognized as compensation expense on a straight-line basis over the requisite service period.

On June 1, 2018, the Company granted 600,000 shares of Company restricted common stock in connection with the Addenda to the Employment Agreements of David Ludwig and Tom Ludwig. The shares are subject to certain restrictions on transfer and a right of repurchase over five years, ending May 31, 2023, and require a continued term of service to the Company. Stock-based compensation expense related to the restricted stock awards, calculated by using the grant date fair value of $0.43 per share, was $38,700 for the nine months ended September 30, 2021. The unrecognized stock-based compensation expense as of September 30, 2021 was approximately $0.1 million.

On March 30, 2021, the Company and Scott West entered into a Separation Agreement and General Release (the “Separation Agreement”). Under the terms of the Separation Agreement, Mr. West’s separation from the Company was effective on March 31, 2021. On April 8, 2021, the Company granted 25,000 shares of the Company’s restricted common stock, which will be forfeited to the Company during the two years following the effective date of the Separation Agreement in the event Mr. West breaches the terms of the Separation Agreement. In addition, the Separation Agreement provides for customary mutual releases by the Company and Mr. West, and the Separation Agreement includes confidentiality, non-disparagement and other obligations. The full amount of the restricted common stock was expensed as of March 31, 2021 and there was no remaining unrecognized stock-based compensation expense as of September 30, 2021.

On March 19, 2019, the Company entered into a Warrant Agreement (the “Warrant Agreement”) with Napier Park Industrial Asset Acquisition LP, a Delaware limited partnership (“Napier Park”).

During the year ended December 31, 2020 and the nine months ended September 30, 2021, Napier Park did not receive any warrants.
