We know of no existing arrangements between Chardan or any other stockholder, broker, dealer, underwriter or agent relating to the sale or distribution of the shares of Common Stock offered by this prospectus.

Conflicts of Interest

Chardan is a member of FINRA and is expected to act as an executing broker for the resale of the shares of our Common Stock in this offering. The receipt by Chardan of all the proceeds from resales of shares of our Common Stock results in a “conflict of interest” under FINRA Rule 5121. Accordingly, such resales will be conducted in compliance with FINRA Rule 5121. To the extent that the shares of our Common Stock do not have a “bona fide public market”, as defined in FINRA Rule 5121, a qualified independent underwriter will participate in the preparation of, and exercise the usual standards of “due diligence” with respect to, the registration statement.

Our Common Stock is listed on Nasdaq under the symbol “SONM.”
