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 Statement on Form S-4 (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), in connection with the proposed offer to exchange the Company’s outstanding unregistered 10.875% Senior Notes due 2024 (the “Original Notes”) for up to $350,000,000 aggregate principal amount of its new 10.875% Senior Notes due 2024 (the “Exchange Notes”). The Exchange Notes will be fully and unconditionally guaranteed by the Company and several additional guarantors identified in the Indenture (as defined below). The Indenture includes the guarantees of the Exchange 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:

(1) an executed copy of the Indenture dated as of February 9, 2016 (the “Initial Indenture”), by and among the Company, EIG Investors Corp, a Delaware corporation (the “Issuer”), the other Endurance Guarantors (as defined therein) party thereto, and Wilmington Trust, National Association, as Trustee (in such capacity, the “Trustee”), as supplemented by the First Supplemental Indenture thereto dated as of February 9, 2016 (the “Supplemental Indenture” and together with the Initial Indenture, the “Indenture”) including all Exhibits thereto;

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

(4) a copy of a certificate, dated November 10, 2016, of the Secretary of State of the State of Florida as to the existence and good standing of the Company as of such date (the “Good Standing Certificate”).

In all such examinations, we have assumed the legal capacity of all natural persons executing documents, the genuineness of all signatures, the authenticity of original and certified documents and the conformity to original or certified copies of all copies submitted to us as conformed or reproduction copies.

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.

Based upon the foregoing, and subject to the limitations, qualifications and assumptions set forth herein, we are of the opinion that:

(a) The Company is a limited liability company existing in good standing under the laws of the State of Florida as of November 10, 2016.

(D) We express no opinion as to the application of, and our opinions above are subject to the effect, if any, of, any applicable fraudulent conveyance, fraudulent transfer, fraudulent obligation or preferential transfer law.

(E) We have not made any investigation of and do not express an opinion as to (i) the descriptions for or any matters of title pertaining to property (whether real, fixtures, personal or mixed) of the Company, or (ii) the validity, perfection, or priority of liens relevant thereto.

(F) The opinions expressed herein are limited to the laws of the State of Florida.
