Subject: Merger of EchoStar and DISH

EchoStar team,

I am pleased to share with you that our pending merger with DISH is progressing well. Yesterday, EchoStar and DISH amended their merger agreement to change the legal structure of the merger. Now, instead of EchoStar merging into a DISH subsidiary, DISH will merge into an EchoStar subsidiary. This does not change our plans for how we will operate the combined business, but it will create greater financial and operational flexibility for the combined company.

As a result of this change, EchoStar shares will no longer be converted into DISH shares. Instead, DISH shares will convert to EchoStar shares at a rate of 0.350877 shares of EchoStar for each share of DISH. This preserves the economics of the original merger plan, and it is still expected that, at closing, DISH shareholders will own approximately 69% of the combined company and EchoStar shareholders will own approximately 31%. The executive leadership and board structure will remain as initially announced.

DISH and EchoStar will continue to operate as independent public companies until the merger closes, which we expect will occur as soon as the end of this year.

We expect that the combined company will offer a broad suite of services, using a superior portfolio of technology, spectrum, engineering, manufacturing, and network management expertise.

If you have questions, or if you receive questions about this news, please pass those to CorpComms@EchoStar.com.

I thank you all for your continued dedication and commitment.

Hamid.
