[1] On June 2, 2017, pursuant to the terms of the Share Exchange Agreement and in consideration of legal services, Microphase issued a $450 8% promissory note with a maturity date of November 25, 2017 to Lucosky Brookman, LLP (the "Lucosky Note"). In conjunction with the issuance of the Lucosky Note, the Company issued Lucosky Brookman 10,000 shares of redeemable convertible Series E preferred stock (the "Series E Preferred Stock") with a stated value of $45 per share as an alternative to providing a guarantee for the amount of the Lucosky Note. The Company, at its option, may redeem for cash, in whole or in part, at any time and from time to time, the shares of Series E Preferred Stock at the time outstanding, upon written notice to the holder of the shares, at a cash redemption price equal to $45 multiplied by the number of shares being redeemed. Any such optional redemption by the Company shall be credited against the Lucosky Note. During the three months ended September 30, 2017 and the period June 3, 2017 to September 30, 2017, Microphase incurred $3 and $6, respectively, of interest on the Lucosky Note. As of September 30, 2017, accrued interest on the Lucosky Note was $6.
