Dear Sirs

1. Introduction

2.12 In providing this Opinion, we have acted for the Companies and no other person, whether or not an Addressee of this Opinion. This Opinion is provided by us to the Addressees and can only be used by Addressees other than the Companies (the “Other Addressees”), strictly subject to and on the basis of the following:

(a) we expressly reserve the right to represent the Companies (if all or any of them so request) in relation to any matters affecting any of the matters which are the subject of or connected with this Opinion at any time in the future (whether or not the Other Addressees retain separate advisers on any such matter) and by the Other Addressees relying or using this Opinion, the Other Addressees accept and confirm that we do and will not have any conflict of interest in relation to such representation;

3. Opinion

Subject to:

(a) the bases of opinion set out in section 2 (Bases of Opinion) above;

(b) the assumptions and reservations set out in sections 4 (Assumptions) and 5 (Reservations and Qualifications), respectively, below; and

(c) any matters or documents not disclosed to us,

we are of the opinion as follows:

3.1 Corporate status

AICD is a designated activity company limited by shares and is duly incorporated under the laws of Ireland. It is incorporated for an indefinite period, is a separate legal entity and is subject to suit in its own name.

(h) the accuracy and completeness of the results of the Searches, that the information disclosed by the Searches was up to date and that the information contained in the Searches has not, since the date and time the Searches were made, been altered and that there was no information which had been delivered for registration or filing that did not appear in the relevant records or files at the time the Searches were made;

Page 7/19

Certificates

(i) the accuracy and completeness of the statements contained in each Certificate and of the documents attached to each Certificate as at the date of the relevant Certificate and on the date of this Opinion and that no further investigation or diligence whatsoever in respect of any matter referred to, or the statements made, in the Certificates (or in the attachments thereto) is required of us by the Addressees;

Governing Law and Foreign Law

(j) as a matter of all relevant laws (other than, insofar as such laws apply to the matters expressly covered by this Opinion, the laws of Ireland):

(i) all obligations under the Documents will, upon execution and, where relevant, delivery thereof, be valid, legally binding upon, and enforceable against, the Parties thereto;

(ii) words and phrases used therein have the same meaning and effect as they would if the Documents were governed by Irish law;

(v) the legal effect of the Documents, and the matters expressed to be effected thereby, as set out in the Documents and the creation of any security or other interest in any assets the subject thereof, will, upon execution and, where relevant, delivery of the Documents, be effective.

For the purposes of this assumption, “relevant laws” in respect of each Document include most notably:

(A) the laws of the jurisdiction of incorporation of each Party and each jurisdiction through which each Party acts for the purposes thereof;

(B) its applicable governing law; and

(C) the lex situs and, if different, the law governing the creation of the assets which are, or purport to be, dealt with under such Document;

Page 8/19

(k) that there are no provisions of the laws of any jurisdiction outside Ireland which are or will be applicable to the Documents which would be contravened by, or are inconsistent with, the execution, performance or delivery of the Documents and that none of the opinions expressed above will be affected by the laws (including the public policy) of any jurisdiction outside Ireland;

(l) insofar as any obligation or right of a Party pursuant to the Documents falls or will fall to be performed or, as the case may be, exercised in any jurisdiction outside Ireland, that its performance or, as the case may be, exercise will not be illegal or ineffective by virtue of the laws of that jurisdiction;

(n) all necessary corporate and shareholder action has been duly and correctly taken by each Party (other than the Companies) to authorise its entry into, delivery and execution of the Documents and to perform its obligations thereunder;

(o) that the Documents have been or (as the case may be) will be (other than in the case of the Companies) duly executed by a person or persons duly authorised to do so on behalf of, and, as necessary, so delivered by, each of the parties thereto in accordance with its constitutional documents and the laws of the jurisdiction under which it is incorporated or otherwise constituted;

Page 9/19

(p) other than the Trustee acting in its capacity as such, each Party acts and shall act as principal and not as agent or in any other capacity whatsoever, fiduciary or otherwise and shall be personally liable as regards the obligations expressed to be owing by it and shall be the beneficial owner of obligations expressed in the Documents to be owed to it;

5. Reservations and Qualifications

Our Opinion is subject to the following reservations and qualifications:

Documents

5.1 Notwithstanding any provision in a Document to the contrary, a Document may be capable of being amended by oral agreement or conduct of the Parties.

5.2 Provisions in a Document imposing additional obligations in the event of breach or default, or of payment or repayment being made other than on an agreed date, may be unenforceable to the extent that they are subsequently adjudicated to be penal in nature. The fact that any payment is held to be penal in nature would not, of itself, prejudice the legality or validity of any other provision contained in the Document which does not provide for the making of such payment.

5.3 Provisions in a Document that determinations, calculations, certifications or acknowledgements are to be conclusive and binding will not necessarily prevent judicial enquiry by the Courts into the merits of any claim by a party claiming to be aggrieved by such determinations, calculations, certifications or acknowledgements; nor do such provisions exclude the possibility of such determinations, calculations, certifications or acknowledgements being amended by order of the Courts.

Page 12/19

5.4 To the extent that a Document vests a discretion in any party, or provides for any party determining any matter in its opinion, the exercise of such discretion and the manner in which such opinion is formed and the grounds on which it is based may be the subject of a judicial enquiry and review by the Courts.

5.5 Provisions of a Document providing for severance of provisions due to illegality, invalidity or unenforceability thereof may not be effective, depending on the nature of the illegality, invalidity or unenforceability in question.

5.6 The effectiveness of terms of a Document exculpating a party from a liability, obligation or duty otherwise owed is limited by law (including, insofar as the liability of trustees is concerned, by section 422 (Liability of trustees for debenture holders) of the Companies Act).

5.7 A person who is not a party to a Document may not be able to enforce any provision thereof which is expressed to be for the benefit of that person.

Insolvency

5.8 The obligations of the Company and each other Party under the Documents are subject to all laws relating to insolvency, bankruptcy, liquidation, receivership, reorganisation, moratorium, examinership, rescue process, trust schemes, preferential creditors, fraudulent disposition, improper transfer, unfair preference, stabilisation, resolution and other similar or applicable laws or regulations relating to or affecting creditors’ rights generally.

5.9 We draw your attention to the fact that the Companies Act provides that a beneficiary (the “beneficiary”) of a guarantee, indemnity or other similar arrangement (the “guarantee”) in respect of the debt of a company to which an examiner has been appointed, may not enforce the guarantee in respect of that liability (even after expiry of the court protection period) unless the beneficiary has, within the periods set out in section 549 of the Companies Act, served notice on the guarantor offering to transfer to the guarantor any rights, so far as they relate to the debt, which the beneficiary may have under section 540 (Consideration by members and creditors of proposals) of the Companies Act to vote in respect of proposals for a compromise or scheme of arrangement in relation to the company. This rule will not apply if:

(a) the guarantor is a company to which an examiner has been appointed; or

(b) both:

(i) a compromise or scheme of arrangement in relation to the company is not entered into or does not take effect under section 542(3) of the Companies Act; and

(ii) the beneficiary has obtained the leave of the Irish High Court to enforce the guarantee.

Similar (but separate) provisions apply in relation to guarantees in the context of a beneficiary’s receipt of notice of a meeting to consider a rescue plan in relation to a small or micro company (pursuant to section 588ZI of the Companies Act and related provisions).

Page 13/19

Enforceability/Binding Nature of Obligations

5.10 The description of obligations as “enforceable” or “binding” refers to the legal character of the obligations in question. It implies no more than that they are of a character which Irish law recognises and enforces. It does not mean that a Document will be binding or enforced in all circumstances or that any particular remedy will be available. Equitable remedies, such as specific performance and injunctive relief, are at the discretion of the Courts and may not be available to persons seeking to enforce provisions of a Document. Furthermore, the Courts may not allow acceleration of obligations under a Document where an event of default occurs that is considered immaterial. More generally, in any proceedings to enforce a Document, the Courts may require that the Party seeking enforcement acts with reasonableness and good faith. Enforcement of a Document may also be limited as a result of (i) the provisions of Irish law applicable to contracts held to have become frustrated by events happening after their execution, or (ii) any breach of the terms of a Document by the Party seeking to enforce the same, or (iii) any applicable regulatory obligation binding on any person whether under any law, code of practice or otherwise.

5.11 Where an obligation is to be performed outside Ireland under a Document, it may not be enforceable in Ireland to the extent that performance would be illegal or contrary to public policy under the laws of that jurisdiction.

5.12 Any judgment of the Courts for moneys due under a Document may be expressed in a currency other than euro but the order may issue out of the Central Office of the High Court expressed in euro by reference to the official rate of exchange prevailing at or shortly before the date of judgment. In addition, in a winding-up in Ireland of an Irish incorporated company, all foreign currency claims must be converted into euro for the purposes of proof. The rate of exchange to be used to convert foreign currency debts into euro for the purposes of proof in a winding-up is the spot rate as of, in the case of a compulsory winding-up, either the date of commencement of the winding-up (presentation of the petition for winding-up or earlier resolution for winding-up) or of the winding-up order and, in the case of a voluntary winding-up, on the date of the relevant winding-up resolution.

5.13 A Court may refuse to give effect to a purported contractual obligation to pay costs arising from unsuccessful litigation brought against a party and may not award by way of costs all of the expenditure incurred by a successful litigator in proceedings before that Court.

5.14 Claims against any Party may be or become the subject of set-off or counterclaim and any waiver of those or other defences available to each Party may not be enforceable in all circumstances.

5.15 Currency indemnities contained in the Documents may not be enforceable in all circumstances.

5.16 Enforcement of the Document will be limited by any contractual restrictions contained therein or applying thereto.

5.17 We draw your attention to the decision in the English case of R (on the application of Mercury Tax Group Ltd) v. Revenue and Customs Commissioners [2008] EWHC 2721. Although this decision is not binding on the Courts it may be considered as persuasive authority in any proceedings before the Courts. One of the decisions in that case would appear to indicate that a previously executed signature page from one document may not be transferred to another document: (i) at all, in the case of a deed and (ii) unless appropriate authorisation has been given, in the case of a simple contract. Our Opinion is qualified by reference to the above referenced decision.

Page 14/19

Statutes of Limitation

5.18 Claims against any Party may become barred under relevant statutes of limitation if not pursued within the time limited by such statutes.

Power of Attorney

5.19 No opinion is expressed on the irrevocability of, or the enforceability of the delegation of, any power of attorney under the Documents.

Power of the Courts to Stay Actions

5.20 The Courts have power to stay an action where proceedings are pending before a court of a jurisdiction that is not an EU Member State (“Other Court”) involving the same cause of action and between the same parties, or which it determines is a related action, so that it is expedient that both actions be heard and determined together to avoid the risk of irreconcilable judgments, if:

(a) it is expected that the Other Court will give a judgment capable of recognition and, where applicable, of enforcement in Ireland; and

(b) the Courts are satisfied that a stay is necessary for the proper administration of justice,

and where staying the action is consistent with Council Regulation (EC) No 1215/2012 of 12 December 2012 on jurisdiction and the recognition and enforcement of judgements in civil and commercial matters (the “Brussels Recast Regulation”). The Courts will not decline any mandatory jurisdiction arising pursuant to the Brussels Recast Regulation.

Offer or Sale of Debt Securities in Ireland

5.22 The underwriting or placement of Debt Securities in or involving Ireland by an Addressee or another person must be in conformity with the provisions of the Companies Act, the European Union (Markets in Financial Instruments) Regulations 2017, Directive 2014/65/EU of the European Parliament and of the Council of 15 May 2014 on markets in financial instruments, Regulation (EU) No. 600/2014 of the European Parliament and of the Council of 15 May 2014 on markets in financial instruments and amending Regulation (EU) No. 648/2012 and all implementing measures, delegated acts and guidance in respect thereof, and the provisions of the Investor Compensation Act 1998.

5.23 An offer of Debt Securities to the public in Ireland or seeking their admission to trading on a regulated market situated or operating in Ireland by an Addressee or another person must be in conformity with the provisions of Regulation (EU) 2017/1129 of the European Parliament and of the Council, the European Union (Prospectus) Regulations 2019, the Central Bank (Investment Market Conduct) Rules 2019 and any other rules issued under section 1363 of the Companies Act by the Central Bank of Ireland.

5.24 To the extent they may apply, underwriting, placing or otherwise acting in Ireland in respect of the Debt Securities by an Addressee or another person must be in conformity with the provisions of the Market Abuse Regulation (EU 596/2014) and the Market Abuse Directive (2014/57/EU) and transposing legislation, including the European Union (Market Abuse) Regulations 2016, and any rules issued under section 1370 of the Companies Act by the Central Bank of Ireland, the Companies Act, the Central Bank Acts 1942 to 2018 and any codes of conduct rules made under section 117(1) of the Central Bank Act 1989.

Electronic Signatures

5.25 The electronic signature of documents in Ireland is governed by both the E-Commerce Act and the eIDAS Regulation. For the purposes of our opinion at paragraph 3.4 (Due execution), we have considered whether any relevant electronic signature meets the requirements to be an “electronic signature” within the meaning of the E-Commerce Act and the eIDAS Regulation. In this regard we note that Article 25(2) of the eIDAS Regulation provides that a “…qualified electronic signature shall have the equivalent legal effect of a handwritten signature.” It is our view that Article 25(2) of the eIDAS Regulation is facilitative rather than mandatory and that it does not preclude the use of an electronic signature that does not constitute a qualified electronic signature to execute a document.

Section 14 (Signatures required to be witnessed) of the E-Commerce Act provides that, where a signature to a document is required to be witnessed, that requirement is “…taken to have been met if…” specified criteria are satisfied (including the use of advanced electronic signatures based on qualified certificates by the signatory and the witness). It is our view that this provision is enabling rather than mandatory and, as such, it is possible for an electronic signature of a document to be witnessed otherwise than by satisfying the criteria set out in section 14, provided that the witness is physically present to witness the use of the electronic signature.

Section 10 (Excluded Laws) of the E-Commerce Act provides that sections 12 to 23 (being the provisions enabling the use of electronic signatures) are “…without prejudice to…the law governing…” matters including (of specific relevance to this Opinion):

(a) “…the creation, execution, amendment, variation or revocation of a trust”; and

(b) “…the manner in which an interest in real property (including a leasehold interest in such property) may be created, acquired, disposed of or registered, other than contracts (whether or not under seal) for the creation, acquisition or disposal of such interests”.

The law governing the above matters includes requirements for documents relating to the above matters to be in writing and signed on behalf of the parties thereto. It is our view that the better interpretation of section 10 of the E-Commerce Act and those laws is that they do not preclude the use of electronic signatures for this purpose but, in the absence of binding judicial authority on the issue, it is not possible to provide a definitive opinion on the issue.
