Dear Richard

Curragh Mine — New Coal Supply Deed

We refer to the Curragh Mine — New Coal Supply Deed between Coronado Curragh Pty Ltd ACN 009 362 565 (Coronado) and Stanwell Corporation Limited ACN 078 848 674 (Stanwell) dated 14 August 2018 as amended (New Coal Supply Deed).

Capitalised terms that are used but not defined in this letter have the meaning specified in the New Coal Supply Deed. Clause and schedule references in this letter are to clauses and schedules in the New Coal Supply Deed.

The definition of Acceptable Security in clause 1.1 includes the Wilmington Amendment of Undertaking, in the form set out in Schedule 7.  As you are aware, Coronado refinanced its external debt in October 2018. Pursuant to that refinancing, Westpac Administration Pty Ltd replaced Wilmington Trust as security trustee and encumbrancee in respect of security granted by Coronado to the refinancing banks (Banks). In conjunction with the refinancing, Westpac Administration Pty Ltd, Stanwell, Coronado and others entered into the Existing Arrangements Intercreditor Deed on 25 October 2018 (Intercreditor Deed).  Under clause 20 of the Intercreditor Deed, Westpac Administration Pty Ltd in its capacity as security trustee gave undertakings to Stanwell which reflect those contemplated in the Wilmington Amendment of Undertaking.  In view of Wilmington Trust’s replacement by Westpac Administration Pty Ltd as encumbrancee and security trustee in respect of security granted by Coronado to the Banks, and the undertakings given by Westpac Administration Pty Ltd in the Intercreditor Deed, we consider that the reference to the Wilmington Amendment of Undertaking in the definition of Acceptable Security in clause 1.1 is now redundant, and should not be required to be provided as part of the Acceptable Security under the New Coal Supply Deed.

In addition, we understand that certain aspects of the Acceptable Security relating to Coronado’s USA operations have not been completed.  Despite this, Coronado wishes to commence mining on the Reserved Area, and seeks Stanwell’s consent in that regard.

If Stanwell agrees that:

(a)the Wilmington Amendment of Undertaking is not required as part of the Acceptable Security provided under the New Coal Supply Deed;

(b)Coronado may commence mining the Reserved Area; and

(c)the provisions of clause 4.2(b) will not apply to such mining,

please execute this letter as a deed in the space provided below and deliver a fully signed counterpart of this letter to the undersigned on behalf of Coronado.
