The shares subject to Baker Mills' offer represent approximately 0.04 percent of the shares of the Company’s outstanding common stock as of the date of the offer. This is the sixth such offer (not including two amended offers) Baker Mills made to Company shareholders this year.

The company does not endorse Baker Mills' unsolicited mini-tender offer and is not associated in any way with Baker Mills, its mini-tender offer, or its mini-tender offer documents.

On December 7, 2018, the Company issued the press release attached to this Report as Exhibit 99, informing its shareholders that the Company does not endorse Baker Mills unsolicited mini-tender offer and recommending that shareholders not tender their shares to Baker Mills.
