12 November  2024 DBSD Services Limited 5 Aldermanbury Square 13th Floor London EC2V 7HR  

(together, “you” or “your”)

DBSD Services Limited (the “Company”)

We have acted as English legal advisers to the Company in connection with the offer and sale of $5,355,999,854 Aggregate Principal Amount of 10.75% Senior Secured Notes due 2029 (the “New Senior Spectrum Secured Notes”) and $ 29,999,993 Aggregate Principal Amount of 3.875% Convertible Senior Secured Notes due 2030 (the “EchoStar Convertible Notes” and, together with the New Senior Spectrum Secured Notes, the “Notes”). Terms used but not otherwise defined in this opinion shall have the meanings given to them in the Opinion Documents (as defined below) and Appendix 1 (as the case may be).

This opinion is limited to English law. We do not undertake to advise you of any changes in our opinions expressed in this letter resulting from matters that may arise after the date of this letter or that hereafter may be brought to our attention. This opinion is given on the basis that it will be governed by, and construed in accordance with, English law and that any dispute arising out of, or in connection with, it shall be subject to the exclusive jurisdiction of the English courts.

For the purposes of this opinion, we have examined each of the documents listed in Appendix 1.

(a) On 11 November 2024 we carried out a search of the Companies House online database and on 11 November 2024 we carried out a search of the filing history page of the Companies House online database in respect of DBSD Services Limited (the “Company Searches”). The Company Searches did not reveal:

(i) any current order or resolution for the winding-up of the Company;

(ii) any current order for the administration of the Company;

(iii) any current notice of appointment in respect of the Company of a liquidator, receiver, administrative receiver or administrator; or

(iv) any current order for a moratorium in respect of the Company.

(b) On 11 November 2024 at 11:09 a.m. London time an information services provider on our behalf made an enquiry of the Central Registry of Winding-up Petitions of the High Court (the “Winding-up Enquiry”) which indicated that no petition for the winding-up of the Company has been presented.

 

12 November 2024  

On the assumptions set out in Appendix 2 and subject to the qualifications set out in Appendix 3, we are of the opinion that:

1. the Company is incorporated in England and Wales and registered in England and Wales as a private limited company.

2. the Company has the requisite corporate capacity and power to enter into the Opinion Documents to which it is a party and to perform its obligations thereunder.

3. the execution by the Company of the Opinion Documents to which it is a party has been duly authorised by all necessary corporate actions on the part of the Company and the execution and performance of the Opinion Documents by the Company does not conflict with or result in any breach or violation by the Company of any term of its articles of association or of any law in force in England applicable to companies generally.

This letter is given solely in connection with the issue of the Exchange Notes. We consent to the filing of this opinion letter as an exhibit to a Current Report on Form 8-K of EchoStar Corporation and its incorporation by reference into the Registration Statement (as defined below). We do not, by giving this consent or otherwise, concede that we are within the category of persons whose consent is required by the Securities Act or the General Rules and Regulations promulgated under the Securities Act, or that we are “experts” in relation to any matters relating to the Opinion Documents, the Notes, or the United States Securities and Exchange Commission (the “Commission”) Registration Statement on Form S-3, as amended by Post-Effective Amendment No. 1 filed with the Securities and Exchange Commission on 5 November 2024 (Registration No. 333-276368) (as amended, or supplemented, the “Registration Statement”), the base prospectus included therein or the prospectus supplement dated 8 November 2024 filed with the Commission pursuant to Rule 424(b) under the Securities Act of 1933, as amended, relating to the offering and sale of the Notes, other than those matters governed by the laws of England and Wales.

Yours faithfully,

Appendix 3

Qualifications

1. The term “enforceable”, as used in this opinion, means that obligations assumed by the Company under the Opinion Documents to which it is a party are of a type which English courts and/or arbitral tribunals applying English law enforce and not that those obligations will necessarily be enforced, whether in court or arbitral proceedings in England or elsewhere, in accordance with their terms.

2. The manner and extent to which the Opinion Documents are enforceable may be affected:

(a) by laws relating to bankruptcy, insolvency, liquidation, administration, receivership, reorganisation, reconstruction (including, in relation to non-UK financial institutions, the Bank Recovery and Resolution Directive (Directive 2014/59/EU) as implemented in the relevant Member State), voidable transactions, moratoria or similar laws generally relating to or otherwise affecting creditors’ rights generally;

(b) by the way in which the English courts and/or any arbitral tribunal applying English law exercise their inherent discretions;

(c) by principles of English law limiting the enforcement or validity of certain terms;

(d) by the implication of contractual terms by the English courts or by any arbitral tribunal applying English law;

(e) by provisions of English law applicable to the vitiation, modification or discharge of contracts;

(f) where the rights and obligations of the respective parties thereunder may be held to have been suspended, impaired or waived by representation, conduct or delay;

(g) where, in the case of any guarantee or surety obligation, equitable defences may relieve a person of such obligations;

(h) by a finding by the English courts or any arbitral tribunal applying English law that a provision of any of the Opinion Documents constitutes a penalty; and

(i) by the interpretation or application of English law by an arbitral tribunal seated in England which is not bound by conflicts of laws as applied by an English court and therefore may differ to the manner in which an English court applies English conflicts of laws rules.

3. Where there is a valid jurisdiction clause in favour of the English courts, the exercise of jurisdiction by the English courts is subject to the following:

(a) an English court will generally only exercise jurisdiction to hear a case and give judgment against a defendant if the defendant has been served with the court proceedings or the court has dispensed with service and consequently where the defendant or its agent cannot be served and service has not been dispensed with, the English courts may not exercise jurisdiction;

(b) an English court may refuse to assume or exercise jurisdiction when it concludes that it is required to do so by the Civil Jurisdiction and Judgments (Amendment) (EU Exit) Regulations 2019 or the Civil Jurisdiction and Judgments (Hague Convention on Choice of Court Agreements 2005) (EU Exit) Regulations 2018; and

6

(c) an English court may stay proceedings on case management grounds if concurrent proceedings are being brought elsewhere.

4. Claims under the Opinion Documents may become subject to a defence of set-off or satisfaction of a counterclaim or time barred under applicable limitation legislation.

5. Any disposition of a company’s property (which may include the grant of security) made after the presentation of a winding up petition against such company will be void unless a court orders otherwise.

6. We do not express any opinion as to the validity or efficacy of any provisions of the Opinion Documents which may circumvent fundamental insolvency law principles including, without limitation, those of mandatory set off and pari passu distribution to creditors, pursuant to the principles of public policy relating to insolvency law. In particular, the effectiveness of contractual subordination arrangements under English law is not definitively established either in legislation or in case law.

7. We express no opinion on any provision of an Opinion Document governed by, or interpreted or construed in accordance with, any law other than English law.

8. We express no opinion on the legal validity and the enforceability of the Opinion Documents.

9. The conclusions expressed in this opinion may be affected by the laws relating to recovery and resolution including the Bank Recovery and Resolution Directive (Directive 2014/59/EU, as amended), and (with respect to UK financial institutions only) the Banking Act 2009 and Part 12A of FSMA, the Financial Services Act 2012, those made under the European Union (Withdrawal) Act 2018 and any secondary legislation, instruments, rules and orders made or which may be made under, or to give effect to, any of them.

10. We express no opinion as to the effect of any calculations (whether expressed in figures or words), formulae (whether expressed in figures or words), quantifications, diagrams, tables, technical specifications contained in the Opinion Documents, including whether or not any of the foregoing achieve the intended or desired legal and/or commercial effect of the parties to the Opinion Documents.

11. Any provisions in the Opinion Documents which amount to agreements to agree may not be enforceable, and we express no opinion on their enforceability.

12. The Company Searches are not capable of revealing conclusively whether or not:

a) a winding-up order has been made or a resolution passed for the winding-up of a company; or

b) an administration order has been made;

c) a moratorium has commenced; or

d) a receiver, administrative receiver, administrator, liquidator or monitor has been appointed,

since notice of these matters may not be filed with the Registrar of Companies immediately and, when filed, may not be entered on the public database or recorded on the public microfiches of the relevant company immediately.

In addition, the Company Searches are not capable of revealing, prior to the making of the relevant order, whether or not a winding-up petition or a petition for an administration order has been presented or an application for a moratorium (or an extension to an existing moratorium) has been filed.

7

13. The Winding-up Enquiry relates only to a compulsory winding-up and is not capable of revealing conclusively whether or not a winding-up petition in respect of a compulsory winding-up has been presented, since details of the petition may not have been entered on the records of the Central Registry of Winding-up Petitions immediately or, in the case of a petition presented to a County Court, may not have been notified to the Central Registry and entered on such records at all, and the response to an enquiry only relates to the period of approximately four years prior to the date when the enquiry was made.

14. The term “performance” as used in this opinion means that obligations assumed by the Company under the Opinion Documents are of a type which may be legally performed. We do not express any opinion as to the manner in which any of the obligations in the Opinion Documents are actually performed by the Company.

15. We express no opinion as to the provisions of the Opinion Documents to the extent it purports to declare or impose a trust in respect of any payments or assets received by any person.

16. Any guarantee or security given by a subsidiary may be unenforceable if giving that guarantee or security amounts to an unlawful distribution to its shareholders or a reduction in its capital. There are no decided cases on the point but, in our opinion if the directors of a company reasonably decide that no provision should be made in the financial statements of a company for their contingent liability under that guarantee or security, the giving of that guarantee or security should not amount to an unlawful distribution or reduction in capital.

17. Any United Nations, United States, European Union or UK sanctions or other similar measures that may be applicable, directly or indirectly, to any party to the Opinion Documents, may result in the obligations of other parties to the Opinion Documents being unenforceable or void or otherwise affected.

18. We express no opinion in respect of the tax treatment of, or transactions contemplated by, the Opinion Documents or on any issues related to taxation.

19. We express no opinion as to the accuracy or truth of any representations and warranties made by any party to the Opinion Documents.

20. The effectiveness of provisions exculpating or limiting a party from liabilities or duties otherwise owed by such party or limiting the remedies available to a party is limited by law and may not be upheld by the English courts.

21. An agreement or a provision in the Opinion Documents that is deemed to lack sufficient certainty (either because such provision is too vague or because it is incomplete) may be void for uncertainty or otherwise unenforceable.

22. Any national or international economic sanctions or other similar measures that may be applicable, directly or indirectly, to any party to the Opinion Documents, may result in the obligations of that party or parties to the Opinion Documents being unenforceable or void or otherwise affected and/or such parties being subject to civil and/or criminal penalties.
