The loan agreement was terminated prior to January 1, 2018. The warrants were due to expire on February 17, 2025.

Preferred Stock Warrants

The warrants granted the customer the right to purchase up to 280,528 shares of the Company’s Series D convertible preferred stock at an exercise price of $0.0001 per share. As the customer remitted payment for goods purchased from the company under the development

agreement, a pro-rata share of warrants vested. The warrants were set to expire on September 24, 2029, but were completely vested and exercised as of the Closing.

The Company accounted for the warrants issued to the customer as consideration payable to the customer and a reduction of revenue with a corresponding adjustment to convertible preferred stock. The Company accounted for the warrants that vested as a reduction to deferred revenue and a corresponding adjustment to convertible preferred stock. The value of the warrants was measured based on the grant date fair value. The grant date was considered to have occurred at the execution date of the development agreement.
