(1) “Voting Shares” include all shares of Class A Common Stock, $0.001 par value per share (“Class A Common Stock”) and Class B Common Stock, $0.001 par value per share (“Class B Common Stock”) of EchoStar Corporation (“EchoStar”) 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) 28 shares of Class A Common Stock beneficially owned directly by Mr. Gouger; (ii) 1,450 shares of Class A Common Stock beneficially owned indirectly by Mr. Gouger in the DISH Network 401(k) Employee Savings Plan; (iii) 1,249,012 shares of Class A Common Stock, including 1,247,372 issuable upon conversion of shares of Class B Common Stock, beneficially owned by Mr. Gouger solely by virtue of his position as trustee (with sole voting and dispositive power) of certain trusts established by Mr. Charles W. Ergen for the benefit of his family; (iv) 3,560,833 shares of Class B Common Stock owned beneficially by Mr. Gouger solely by virtue of his position as trustee (with sole voting and dispositive power, except as set forth in Item 6 below) of the Ergen 2010 Family Trust (the “2010 Family Trust”); (v) 7,074,796 shares of Class B Common Stock beneficially owned by Mr. Gouger solely by virtue of his position as trustee (with sole voting and dispositive power, except as set forth in Item 6 below) of the Ergen Three-Year 2014 SATS GRAT (the “2014 GRAT”); and (vi) 9,000,000 shares of Class B Common Stock beneficially owned by Mr. Gouger solely by virtue of his position as trustee (with sole voting and dispositive power, except as set forth in Item 6 below) of the Ergen Three-Year 2015 SATS GRAT (the “2015 GRAT”). There is no arrangement or agreement between any of the trusts identified in clauses (iii) through (vi) above to vote or dispose of any shares of EchoStar.  Mr. Gouger exercises voting and dispositive power with respect to each such trust independently and in accordance with his fiduciary responsibilities to the beneficiaries of such trusts.

(2) Based on 44,941,806 shares of Class A Common Stock outstanding on November 25, 2015 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 beneficially own would be approximately 22.5%.  Because each share of Class B Common Stock is entitled to 10 votes per share, Mr. Gouger beneficially owns equity securities of EchoStar representing approximately 40.0% of the voting power of EchoStar (assuming no conversion of the Class B Common Stock and no conversion of EchoStar’s outstanding preferred tracking shares).

(1) All of the shares beneficially held by the 2010 Family 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 44,941,806 shares of Class A Common Stock outstanding on November 25, 2015 and assuming conversion of the shares of Class B Common Stock held by the Reporting Person 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 Reporting Person may be deemed to beneficially own would be approximately 3.8%. Because each share of Class B Common Stock is entitled to 10 votes per share, the Reporting Person beneficially owns equity securities of EchoStar representing approximately 6.8% of the voting power of EchoStar (assuming no conversion of the Class B Common Stock and no conversion of EchoStar’s outstanding preferred tracking shares).

(1) All of the shares beneficially held by the 2014 GRAT 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 44,941,806 shares of Class A Common Stock outstanding on November 25, 2015 and assuming conversion of the shares of Class B Common Stock held by the Reporting Person 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 Reporting Person may be deemed to beneficially own would be approximately 7.6%. Because each share of Class B Common Stock is entitled to 10 votes per share, the Reporting Person beneficially owns equity securities of EchoStar representing approximately 13.5% of the voting power of EchoStar (assuming no conversion of the Class B Common Stock and no conversion of EchoStar’s outstanding preferred tracking shares).

(1) All of the shares beneficially held by the 2015 GRAT 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 44,941,806 shares of Class A Common Stock outstanding on November 25, 2015 and assuming conversion of the shares of Class B Common Stock held by the Reporting Person 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 Reporting Person may be deemed to beneficially own would be approximately 9.7%. Because each share of Class B Common Stock is entitled to 10 votes per share, the Reporting Person beneficially owns equity securities of EchoStar representing approximately 17.2% of the voting power of EchoStar (assuming no conversion of the Class B Common Stock and no conversion of EchoStar’s outstanding preferred tracking shares).

5

(1) All of the shares beneficially held by the Ergen Five-Year 2010 SATS GRAT (the “2010 Five-Year GRAT”) were 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.  On November 30, 2015, the 2010 Five-Year GRAT distributed (i) 380,240 shares of Class B Common Stock held by the 2010 Five-Year GRAT to Mr. Ergen as an annuity payment, and (ii) the remaining 1,076,458 shares of Class B Common Stock held by the 2010 Five-Year GRAT to the 2010 Family Trust.  On November 30, 2015, the 2010 Five-Year GRAT expired in accordance with its terms.

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 Reporting Person may be deemed to beneficially own would be approximately 0.0%. Because each share of Class B Common Stock is entitled to 10 votes per share, the Reporting Person beneficially owns equity securities of EchoStar representing approximately 0.0% of the voting power of EchoStar (assuming no conversion of the Class B Common Stock and no conversion of EchoStar’s outstanding preferred tracking shares).
