The Side Letter provided, among other things, for (i) the extension of the expiration date of the Issuer’s $2,500,000 rights offering from March 1, 2019 to April 5, 2019 (the “Rights Offering”); (ii) the exercise by Unilumin on March 4, 2019 of the Warrant for the purchase of 2,061,856 shares of Common Stock; and (iii) the future exercise by Unilumin of the Warrant to purchase the remaining 3,608,247 shares of Common Stock under the Warrant simultaneously with the closing of the Rights Offering.

The aggregate number of shares of Common Stock which Unilumin holds as a result of the November 2, 2018 private placement, and following the exercise in full of the Warrant, is 6,985,892.
