1.2	such corporate records of the Company as we have deemed necessary as a basis for the opinions hereinafter expressed.

In rendering this Opinion, we have examined, and have assumed, without any responsibility on our part if any assumption proves to have been untrue as we have not independently verified any assumption, the truth, accuracy and completeness of the contents of, all such records, documents and certificates of officers of the Company and of public officials as to factual matters and have conducted such searches on 14 May 2026 (being the last practicable date on which searches could be conducted) in public registries in Ireland as we have deemed necessary or appropriate for the purposes of this Opinion but have made no independent investigation regarding such factual matters. In our examination we have assumed the (continued) truth, accuracy and completeness of the information contained in such documents, the genuineness of all signatures (electronic or otherwise), that any signatures (electronic or otherwise) are the signatures of the persons who they purport to be, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such documents.
