In connection with the opinions expressed below, we have assumed that, at and prior to the time of the issuance and delivery of any Securities by the Company pursuant to the Registration Statement, (i) the Registration Statement has been declared effective and no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings with respect thereto have been commenced or threatened, (ii) all relevant corporate actions heretofore taken by the Company remain in full force and effect, (iii) the Merger Agreement governing the Merger has been duly adopted and the Merger has been duly approved by all necessary corporate action of the Company, Merger Subsidiary and NMM, (iv) there has not occurred any change in law materially adversely affecting the power of the Company to issue and deliver the Securities or the validity of such Securities, and (v) the Company will comply with all applicable notice requirements regarding uncertificated shares provided in the General Corporation Law of the State of Delaware.

(5)         We do not express any opinion as to the enforceability of provisions relating to evidentiary standards or other standards by which the Warrants are to be construed.
