without having made any investigation, that the terms of the Indentures are lawful and fully enforceable under the laws of the State of New York and any other applicable laws other than the laws of Ireland;

that the Indentures have each been executed and delivered by each of the parties thereto (other than the Company and ITIL) in the respective forms examined by us;

the due authorisation, execution and delivery of the Indentures by each of the parties thereto (other than the Company and ITIL) and that the performance thereof is within the capacity and power of each of the parties thereto (other than the Company and ITIL);

that each of the parties to the Indentures (other than the Company and ITIL) are able lawfully to enter into such agreement or deed;

that the Company has entered into the Indentures and the Guarantees in good faith, for its legitimate business purposes, for good consideration, and that the Company derives commercial benefit from the Indentures and the Guarantees commensurate with the risks undertaken by it in the Indentures and the Guarantees.

Subject to the foregoing and to the within additional qualifications and assumptions, and based upon searches carried out in the Irish Companies Registration Office and the Central Office of the High Court on 6 August 2020, we are of the opinion that:

the Company is a company duly incorporated under the laws of Ireland and validly existing under the laws of Ireland;

the Company has duly authorized, executed and delivered the Indentures (including the Guarantees);

the Company has the necessary power and authority, and all necessary corporate and other action has been taken, to enable it to execute, deliver and perform the obligations undertaken by it under the Indentures, the Guarantees and the Subscription Rights, and that the implementation by the Company of the foregoing and the issuance by the Company of the Subscription Rights and the Exchange Shares will not cause:

a violation of the PLC Constitution; or

any law or order to be contravened;

the issue of the Subscription Rights has been duly authorised by the Company and, when issued, the Subscription Rights will be valid and binding obligations of the Company;

the allotment and issue of the Exchange Shares has been duly authorised and when issued in accordance with the EN Indenture and the Exchangeable Notes, the Exchange Shares will be validly issued, fully paid and free of pre-emptive rights under Irish law or the PLC Constitution and will not be subject to calls for any additional payments (non-assessable);

in any proceedings taken in Ireland for the enforcement of the Notes and the Indentures, the choice of the laws of the State of New York as the governing law of the contractual rights and obligations of the parties under the Notes and the Indentures and the submission by the parties to the exclusive jurisdiction of the federal courts of the United States or the courts of New York, in each case located in the Borough of Manhattan (the Specified Courts), would be upheld by the Irish Courts in accordance with or subject to the provisions of the Rome 1 Regulation EC No 593/2008 on the Law Applicable to Contractual Obligations, meaning that the courts of Ireland may only refuse to apply the choice of laws of the State of New York if such application is manifestly incompatible with Irish public policy (at the date hereof, we are not aware of any circumstances concerning the choice of the laws of the State of New York that would give rise to an Irish court holding that such choice violates Irish public policy, but it should be noted that matters of public policy are subjective and evolving);

in any proceedings taken in Ireland for the enforcement of a judgment obtained against the Company in the Specified Courts (a Foreign Judgment), the Foreign Judgment would be recognised and enforced by the courts of Ireland save that to enforce such a Foreign Judgment in Ireland it would be necessary to obtain an order of the Irish courts. Such order should be granted on proper proof of the Foreign Judgment without any re-trial or examination of the merits of the case subject to the following qualifications:

that the foreign court had jurisdiction, according to the laws of Ireland;

that the Foreign Judgment was not obtained by fraud;

that the Foreign Judgment is not contrary to public policy or natural justice as understood in Irish law;

that the Foreign Judgment is final and conclusive;

that the Foreign Judgment is for a definite sum of money; and

that the procedural rules of the court giving the Foreign Judgment have been observed.

The opinions set forth in this opinion are given subject to the following qualifications:

an order of specific performance or any other equitable remedy is a discretionary remedy and is not available when damages are considered to be an adequate remedy;

this opinion is given subject to general provisions of Irish law relating to insolvency, bankruptcy, liquidation, reorganisation, receivership, moratoria, court scheme of arrangement, administration and examination, and the fraudulent preference of creditors and other Irish law generally affecting the rights of creditors;

if an adjustment to the exchange rate under the EN Indenture increases the number of Exchange Shares deliverable on an exchange, the Company may not have sufficient authorised ordinary share capital to satisfy the issuance of such Additional Exchange Shares, or the directors of the Company may not have sufficient authority to issue such Additional Exchange Shares on a non-pre-emptive basis and, as such, shareholder approval may need to be sought to (i) increase the authorised share capital of the Company and/or (ii) authorise the Company and the directors of the Company to allot and issue the Additional Exchange Shares on a non-pre-emptive basis;

this opinion is subject to the general laws relating to the limitation of actions in Ireland;

a determination, description, calculation, opinion or certificate of any person as to any matter provided for in the Indentures might be held by the Irish courts not to be final, conclusive or binding if it could be shown to have an unreasonable, incorrect, or arbitrary basis or not to have been made in good faith;

additional interest imposed by any clause of the Indentures might be held to constitute a penalty and the provisions of that clause imposing additional interest would thus be held to be void. The fact that such provisions are held to be void would not in itself prejudice the legality and enforceability of any other provisions of the Indentures but could restrict the amount recoverable by way of interest under such Indentures;

claims may be or become subject to defences of set-off or counter-claim;

an Irish court has power to stay an action where it is shown that there is some other forum having competent jurisdiction which is more appropriate for the trial of the action, in which the case can be tried more suitably for the interests of all the parties and the ends of justice, and where staying the action is not inconsistent with Regulation (EU) No 1215/2012 on jurisdiction and the recognition and enforcement of judgments in civil and commercial matters (recast);

the enforceability of severance clauses is at the discretion of the court and may not be enforceable in all circumstances;

a waiver of all defences to any proceedings may not be enforceable;

any transfer of, or payment in respect of a Note (including the Guarantee thereof) or agreement involving any country or person which is currently the subject of an order made by the Minister for Finance of Ireland restricting financial transfers pursuant to the Financial Transfers Act, 1992 and/or Section 42 of the Criminal Justice (Terrorist Offences) Act, 2005 and any transfer of, or payment in respect of, a Note or agreement involving the government of any country which is currently the subject of United Nations sanctions, any person or body resident in, incorporated in or constituted under the laws of any such country or exercising public functions in any such country or any person or body controlled by any of the foregoing may be subject to restrictions pursuant to such sanctions as implemented in Irish law; and

we express no opinion on any taxation matters or on the contractual terms of the relevant documents other than by reference to the legal character thereof.
