SMC acknowledges that ACM has no obligation to register or qualify for resale the New Warrant or the New Warrant Shares, except as contemplated by the Registration Rights Agreement with respect to the New Warrant Shares, pursuant to the Adoption Agreement. SMC further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including the time and manner of sale, the holding period for the New Warrant or the New Warrant Shares, as applicable, and on requirements relating to ACM that are outside of SMC’s control and that ACM is under no obligation, and may not be able, to satisfy.

4.8     Legends. SMC understands that the New Warrant and, if and when issued, the New Warrant Shares, which will be held in book-entry form, may be notated with restrictive legends as ACM and its counsel deem necessary or advisable under applicable law or pursuant to this Amendment or the New Warrant, including a legend substantially to the following effect:

“THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933. SUCH SECURITIES MAY NOT BE SOLD, PLEDGED, OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR A VALID EXEMPTION FROM THE REGISTRATION OF THE U.S. SECURITIES ACT OF 1933.”

4.9    Investor Status. SMC is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities Act and is not a U.S. person as defined in Regulation S under the Securities Act.

At the time of the origination of discussion regarding the offer and sale of the New Warrant and the date of the execution and delivery of this Amendment, SMC was at all times outside of the United States. SMC has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to receive the New Warrant or the New Warrant Shares, as applicable, or any use of this Amendment, including (a) the legal requirements within its jurisdiction for the purchase of the New Warrant or the New Warrant Shares, as applicable, (b) any foreign exchange restrictions applicable to such purchase, (c) any governmental or other consents that may need to be obtained, (d) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale, or transfer of the New Warrant or the New Warrant Shares, as applicable, and (e) SMC’s receipt and continued beneficial ownership of the New Warrant or the New Warrant Shares, as applicable, will not violate any applicable securities or other laws of SMC’s jurisdiction.
