On April 24, 2018, the Company announced a private exchange offer (“Exchange Offer”), to all holders of the Series B Preferred Stock (the “Series B Preferred Stock”) of East Tennessee Materials and Energy Corporation, a Tennessee corporation (“M&EC”) and a subsidiary of the Company, to exchange, for every share of Series B Preferred Stock tendered, (a) 0.1050805 shares of newly issued common stock of the Company, par value $.001 per share (“Common Stock”), and (b) cash in lieu of fractional shares of Common Stock that would otherwise be issuable to the tendering holder of Series B Preferred Stock, in an amount equal to such fractional share of Common Stock multiplied by the closing price per share of the Common Stock on the last trading day immediately preceding the expiration date of the Exchange Offer. The Exchange Offer is being made on an all-or-none basis, for all 1,284,730 shares of Series B Preferred Stock outstanding and will expire at Midnight, Eastern Standard Time, on May 30, 2018, unless extended or earlier terminated by the Company. Assuming all currently outstanding shares of Series B Preferred Stock are tendered for exchange and not validly withdrawn, the Company would issue an amount of its shares of Common Stock not to exceed 135,000. The Company owns 100% of the voting capital stock of M&EC.

The shares of Company common stock to be issued in exchange for shares of M&EC’s Series B Preferred Stock will be issued pursuant to an exemption from registration under the Securities Act of 1933, as amended, and, as a result, will be considered restricted securities that have restrictions on transferability.

This report does not constitute an offer or an invitation by the Company to participate in the Exchange Offer in any manner, including in any jurisdiction in which it is unlawful to make such an offer or solicitation in such jurisdiction.

A copy of the Company’s press release issued in connection with this announcement is attached hereto as Exhibit 99.1 and incorporated herein by reference.
