satisfactory to the Company that such registration is not required or (2) unless sold pursuant to Rule 144 of such Act or in an offshore transaction (as defined in Regulation S under such Act) in accordance with Regulation S. If the holder of these
securities is a non-U.S. person within the meaning of Regulation S under such Act, such holder agrees not to, directly or indirectly, engage in any hedging transaction with regard to this security or any common stock issuable upon conversion of this
security except as permitted by such Act.”
