The purchase price was paid to the Company on February 1, 2019 less certain amounts to be held in escrow, as provided in the Asset Purchase Agreement among the Company parties and the Buyer (Purchase Agreement), to secure the Company’s obligations to pay its working capital adjustment and indemnification obligations under the Purchase Agreement.
