This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.
 
We have examined the Registration Statement, the exhibits thereto, the certificate of incorporation of the Company, as amended to the date hereof (the “Charter”), the bylaws of the Company, as amended to the date hereof (the “Bylaws”), and the resolutions adopted by the board of directors of the Company relating to the Registration Statement, the SFV Merger Agreement, the TCS Merger Agreement, the Spruce Letter Agreement, the Indenture and the issuance by the Company of the Issued Shares, the Convertible Notes and the Conversion Shares issuable upon conversion of the respective Convertible Notes. We have also examined originals, or copies of originals certified to our satisfaction, of such agreements, documents, certificates and statements of the Company and others, and have examined such questions of law, as we have considered relevant and necessary as a basis for this opinion letter.  We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of all persons and the conformity with the original documents of any copies thereof submitted to us for examination.  As to facts relevant to the opinions expressed herein, we have relied without independent investigation or verification upon, and assumed the accuracy and completeness of, certificates, letters and oral and written statements and representations of public officials and officers and other representatives of the Company.
 
Based on and subject to the foregoing and the other limitations, qualifications and assumptions set forth herein, including that the Registration Statement, as finally amended (including any necessary post-effective amendments), shall have become effective under the Securities Act, we are of the opinion that:
 
 
1.
The Issued Shares are validly issued,  fully paid and non-assessable.
 
 
2.
The Conversion Shares will be validly issued, fully paid and non-assessable when: (i) the Convertible Notes have been duly converted into Conversion Shares in accordance with the terms of the Indenture and (ii) the Company’s books reflect the issuance of such Conversion Shares to the respective holders of such Convertible Notes.
 
In rendering the opinion set forth in paragraph (2) above, we have assumed that, at the time of the issuance and delivery of any Conversion Shares, (i) the authorization thereof by the Company will not have been modified or rescinded, and there will not have occurred any change in law affecting the validity, legally binding character or enforceability thereof; (ii) the Charter and Bylaws, as currently in effect, will not have been modified or amended and will be in full force and effect; (iii) there will be a sufficient number of shares of Common Stock authorized and then available for issuance under the Charter as in effect at the time; and (iv) the requisite stockholder approval under the listing rules of the New York Stock Exchange or the Nasdaq Stock Market LLC, as applicable, to issue the Conversion Shares will have been obtained.
