DISH Network Corporation

Englewood, CO 80112

Ladies and Gentlemen:

In connection with the registration under the Securities Act of 1933 (the “Act”) of (i) shares of Class A common stock, par value $0.01 per share (the “Class A Common Stock”) of DISH Network Corporation, a Nevada corporation (the “Company”), (ii) subscription rights to purchase the Class A Common Stock, (iii) shares of preferred stock of the Company and (iv) debt securities of the Company (the “Debt Securities”), pursuant to a Registration Statement on Form S-3 (the “Registration Statement”) we, as your counsel, have examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion.

Upon the basis of such examination, it is our opinion that when the Registration Statement has become effective under the Act, the indenture relating to the Debt Securities has been duly authorized, executed and delivered, the terms of the Debt Securities and of their issuance and sale have been duly established in conformity with the applicable indenture so as not to violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company, and the Debt Securities have been duly executed and authenticated in accordance with the applicable indenture and issued and sold as contemplated in the Registration Statement, the Debt Securities will constitute valid and legally binding obligations of the Company, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

In rendering the foregoing opinion, we are expressing no opinion as to Federal or state laws relating to fraudulent transfers and we are not passing upon, and assume no responsibility for, any disclosure in any registration statement or any related prospectus or other offering material relating to the offer and sale of the Debt Securities.

We note that, as of the date of this opinion, a judgment for money in an action based on a Debt Security in a Federal or state court in the United States ordinarily would be enforced in the United States only in United States dollars. The date used to determine the rate of conversion of the foreign currency or currency unit in which a particular Debt Security is denominated into United States dollars will depend upon various factors, including which court renders the judgment. In the case of a Debt Security denominated in a foreign currency, a state court in the State of New York rendering a judgment on such Debt Security would be required under Section 27 of the New York Judiciary Law to render such judgment in the foreign currency in which the Debt Security is denominated, and such judgment would be converted into United States dollars at the exchange rate prevailing on the date of entry of the judgment.

The foregoing opinion is limited to the Federal laws of the United States and the laws of the State of New York, and we are expressing no opinion as to the effect of the laws of any other jurisdiction. With respect to all matters of Nevada law, we note that you have received an opinion, dated as of the date hereof, of Timothy A. Messner, Executive Vice President and General Counsel of the Company.

We have relied as to certain factual matters on information obtained from public officials, officers of the Company and other sources believed by us to be responsible, and we have assumed that the Company has been duly incorporated and is an existing corporation in good standing under the laws of the State of Nevada, an assumption which we have not independently verified. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the references to us under the heading “Legal Matters” in the prospectus contained therein. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act.

Very truly yours,

/s/ Sullivan & Cromwell LLP
