3.    Each of the parties (other than the Company) executing any of the Documents has duly and validly executed and delivered each of the Documents to which such party is a signatory, and such party’s (including the Company’s) obligations set forth therein are legal, valid and binding.

4.    All Documents submitted to us as originals are authentic. All Documents submitted to us as certified or photostatic copies conform to the original documents. All signatures on all such Documents are genuine. All public records reviewed or relied upon by us or on our behalf are true and complete. All statements and information contained in the Documents are true and complete. There has been no oral or written modification or amendment to the Documents, or waiver of any provision of the Documents, by action or omission of the parties or otherwise. Each Document submitted to us as a form will be executed by the parties thereto in the form in which it was submitted to us and in a manner consistent with the opinion stated herein.

5.    Prior to the issuance of any Shares, the Company will have available for issuance, under the Charter, the requisite number of authorized but unissued shares of capital stock.
