4. All Documents submitted to us as originals are authentic. The form and content of all Documents submitted to us as unexecuted drafts do not differ in any respect relevant to this opinion from the form and content of such Documents as executed and delivered. All Documents submitted to us as certified or photostatic copies conform to the original documents. All signatures on all Documents are genuine.

5. The issuance of, and certain terms of, the Securities to be issued by the Company from time to time will be authorized and approved by the Board, or a duly authorized committee thereof, in accordance with and not in violation of the Maryland General Corporation Law, the Charter, the Bylaws and the Resolutions and reflected, to the extent applicable, in appropriate governing documents (with such approvals referred to hereinafter as the “Corporate Proceedings”) prior to the issuance thereof.

6. Articles Supplementary classifying and designating the number of shares and the terms of any class or series of Preferred Shares to be issued by the Company will be filed with and accepted for record by the SDAT prior to the issuance of such Preferred Shares, including any Preferred Shares which may be issued upon conversion or exercise of any other Securities convertible into or exercisable for Preferred Shares.
