(1) “Voting Shares” include all shares of Class A Common Stock (“Class A Common Stock”) and Class B Common Stock (“Class B Common Stock”) of DISH Network Corporation (“DISH Network”) of which Mr. Gouger is the sole beneficial owner. The shares of Class B Common Stock are convertible into shares of Class A Common Stock on a one-for-one basis at any time. The Voting Shares represent: (i) 140 shares of Class A Common Stock owned beneficially directly by Mr. Gouger; (ii) 7,249 shares of Class A Common Stock owned beneficially indirectly by Mr. Gouger through DISH Network’s 401(k) Employee Savings Plan; (iii) 8,185 shares of Class A Common Stock owned beneficially by Mr. Gouger solely by virtue of his position as the sole member of the investment committee (with sole voting and dispositive power) of Centennial Fiduciary Management LLC, which serves as trustee of certain trusts established by Charles W. Ergen for the benefit of his family; (iv) 4,245,151 shares of Class B Common Stock owned beneficially by Mr. Gouger solely by virtue of his position as the sole member of the investment committee (with sole voting and dispositive power) of Centennial Fiduciary Management LLC, which serves as trustee of certain trusts established by Charles W. Ergen for the benefit of his family; and (v) 29,545,469 shares of Class B Common Stock owned beneficially by Mr. Gouger solely by virtue of his position as the sole member of the investment committee (with sole voting and dispositive power, except as set forth in Item 6 below) of Centennial Fiduciary Management LLC, which serves as trustee of the Ergen 2010 Family Wyoming Trust (which was formerly known as the Ergen 2010 Family Trust and changed its name effective January 1, 2017). There is no arrangement or agreement between any of the trusts identified in clauses (iii) through (v) above to vote or dispose of any shares of DISH Network.  Solely by virtue of his position as the sole member of the investment committee of Centennial Fiduciary Management LLC, which serves as trustee, Mr. Gouger exercises voting and dispositive power on behalf of Centennial Fiduciary Management LLC with respect to each such trust independently and in accordance with Centennial Fiduciary Management LLC’s fiduciary responsibilities to the beneficiaries of such trusts.

(2) Based on 226,776,724 shares of Class A Common Stock outstanding on December 30, 2016 and assuming conversion of the shares of Class B Common Stock held by Mr. Gouger into Class A Common Stock. Because such Class B Common Stock is convertible on a one-for-one basis into Class A Common Stock, assuming conversion of all shares of outstanding Class B Common Stock into Class A Common Stock, the percentage of the Class A Common Stock that Mr. Gouger may be deemed to own beneficially would be approximately 7.3%. Because each share of Class B Common Stock is entitled to 10 votes per share, Mr. Gouger owns beneficially equity securities of DISH Network representing approximately 12.9% of the voting power of DISH Network (assuming no conversion of the Class B Common Stock).

(1) “Voting Shares” include all shares of Class A Common Stock and Class B Common Stock of DISH Network of which Centennial Fiduciary Management LLC is the sole beneficial owner.

The Voting Shares represent: (i) 8,185 shares of Class A Common Stock owned beneficially by Centennial Fiduciary Management LLC solely in its capacity as trustee (with sole voting and dispositive power) of certain trusts established by Charles W. Ergen for the benefit of his family; (ii) 4,245,151 shares of Class B Common Stock owned beneficially by Centennial Fiduciary Management LLC solely in its capacity as trustee (with sole voting and dispositive power) of certain trusts established by Charles W. Ergen for the benefit of his family; and (iii) 29,545,469 shares of Class B Common Stock owned beneficially by Centennial Fiduciary Management LLC solely in its capacity as trustee (with sole voting and dispositive power, except as set forth in Item 6 below) of the Ergen 2010 Family Wyoming Trust.

(2) Based on 226,776,724 shares of Class A Common Stock outstanding on December 30, 2016 and assuming conversion of the shares of Class B Common Stock held by Centennial Fiduciary Management LLC into Class A Common Stock. Because such Class B Common Stock is convertible on a one-for-one basis into Class A Common Stock, assuming conversion of all shares of outstanding Class B Common Stock into Class A Common Stock, the percentage of the Class A Common Stock that Centennial Fiduciary Management LLC may be deemed to own beneficially would be approximately 7.3%. Because each share of Class B Common Stock is entitled to 10 votes per share, Centennial Fiduciary Management LLC owns beneficially equity securities of DISH Network representing approximately 12.9% of the voting power of DISH Network (assuming no conversion of the Class B Common Stock).

(1) All of the shares beneficially held by the Ergen 2010 Family Wyoming Trust are shares of Class B Common Stock. The shares of Class B Common Stock are convertible into shares of Class A Common Stock on a one-for-one basis at any time.

(2) Based on 226,776,724 shares of Class A Common Stock outstanding on December 30, 2016 and assuming conversion of the shares of Class B Common Stock held by the Ergen 2010 Family Wyoming Trust into Class A Common Stock. Because such Class B Common Stock is convertible on a one-for-one basis into Class A Common Stock, assuming conversion of all shares of outstanding Class B Common Stock into Class A Common Stock, the percentage of the Class A Common Stock that the Ergen 2010 Family Wyoming Trust may be deemed to own beneficially would be approximately 6.4%. Because each share of Class B Common Stock is entitled to 10 votes per share, the Ergen 2010 Family Wyoming Trust owns beneficially equity securities of DISH Network representing approximately 11.3% of the voting power of DISH Network (assuming no conversion of the Class B Common Stock).

(b)  (i) See Items 7 through 10 of the cover pages to this Amendment No. 3 for the number of shares of Class A Common Stock beneficially owned by each of the Reporting Persons as to which there is sole power to vote or to direct the vote, shared power to vote or to direct the vote and sole or shared power to dispose or to direct the disposition.

The trust agreement for the Ergen 2010 Family Wyoming Trust contains an irrevocable provision that provides that the trustee will not dispose of any shares of DISH Network held by the Ergen 2010 Family Wyoming Trust unless a Change of Control Event occurs.  If a Change of Control Event occurs, the trustee of the Ergen 2010 Family Wyoming Trust will have sole discretion with respect to the disposition of any shares of DISH Network held by the Ergen 2010 Family Wyoming Trust.

A “Change of Control Event” will occur if (i) as the result of a transaction or a series of transactions any person other than Charles W.
