Ladies and Gentlemen:

We have acted as special Florida counsel for HostGator.com LLC, a Florida limited liability company (the “Company”), in connection with (i) the Registration Statements on Form S-3 (the “Registration Statements”) filed with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), in connection with market-making activities by an affiliate of EIG Investors, Corp., a Delaware corporation (the “Issuer”), in respect of the Issuer’s 10.875% Senior Notes due 2024 (the “Notes”). The Notes are fully and unconditionally guaranteed by the Company, a subsidiary of the Issuer, and several additional guarantors identified in the Indenture (as defined below). The Indenture includes the guarantees of the Notes by the Company and each other guarantor party thereto. With your permission, all assumptions and statements of reliance herein have been made without any independent investigation or verification on our part except to the extent, if any, otherwise expressly stated, and we express no opinion with respect to the subject matter or accuracy of the assumptions or items upon which we have relied. Capitalized terms used herein and not otherwise defined herein have the meanings assigned to such terms in the Indenture.

In connection with the opinions expressed herein, we have examined such documents, records and matters of law as we have deemed necessary for the purposes of such opinions. We have examined, among other items, the following documents dated as of the date hereof unless otherwise specified:

(3)

Written Consent Adopted by the Sole Member of the Company, dated February 7, 2016; and

In connection with the opinions expressed in the first sentence of paragraph (a) below, we have relied solely upon the Good Standing Certificate as to the factual matters and legal conclusions set forth therein.
