The opinion set forth above as regards the binding effect and validity of the obligations and their enforceability against contracting parties is subject to all limitations resulting from the laws of bankruptcy, administration, liquidation, insolvency, fraudulent transfer, reorganisation, moratorium, suretyship or any similar laws of general application affecting creditors’ rights.

Enforcement may be limited by general principles of equity. For example, equitable remedies may not be available where damages are considered to be an adequate remedy.

The power of an English court to order specific performance of an obligation or to grant injunctive relief or any equitable remedy is discretionary and, accordingly, we express no opinion as to whether such remedies would be available in respect of any of the obligations of the parties. Specific performance is not usually ordered and an injunction is not usually granted where damages would be regarded by the court as an adequate remedy.

If the performance of the payment obligations of the Issuer under the Notes in respect of which the subscription moneys, interest and principal are not all payable in the same currency is contrary to the exchange control regulation of any country in whose currency such amounts are payable, those obligations may be unenforceable in England by reason of Section 2(b) of Article VIII of the International Monetary Fund Agreement and the Bretton Woods Agreements Order in Council 1946.

Where any person is vested with a discretion, or may determine any matter in its opinion, English law may require that such discretion is exercised reasonably or that such opinion is based on reasonable grounds.

Enforcement of rights may be or become limited by prescription or by the lapse of time or barred under the Limitation Act 1980 or may be or become subject to defences of set-off or counterclaim.

An English court is able, where the amount of a claim is denominated in a currency other than sterling, to give judgment in that other currency, as a matter of current procedural practice and at its own discretion.

On 31 January 2020, the United Kingdom ceased to be a member of the European Union (“EU”). By virtue of sections 1A and 1B of the EUWA, EU law continued to be applicable in the United Kingdom for the duration of the implementation period set out in section 1A(6) of the EUWA (“Transition Period”). After the Transition Period, pursuant to sections 2 to 4 of the EUWA, certain EU laws in effect immediately before the end of the Transition Period form part of English domestic law. However, EU law otherwise ceased to be applicable in the United Kingdom and thus does not form part of English law on and after 1 January 2021. We therefore express no opinion in this letter on the effect of EU law in the United Kingdom or on EU law itself.

From 1 January 2021, the Lugano Convention on Jurisdiction and the Enforcement of Judgments in Civil and Commercial Matters of 2007 (“Lugano Convention”) no longer applies to the United Kingdom. Jurisdiction and enforcement will be determined in accordance with the Hague Choice of Court Convention 2005 (the “Hague Convention”) and national laws. Although the United Kingdom has acceded to the Hague Convention in its own right, with effect from 1 January 2021, only exclusive jurisdiction clauses fall within scope of the Hague Convention. Accordingly, jurisdiction clauses that are held to be non-exclusive or unilateral will not be enforceable pursuant to the Hague Convention. Further, in certain circumstances, an English court has power to stay an action commenced in the English courts where it is shown that it can, without injustice to the claimant, be tried in a more convenient forum. However, such power may not be exercisable in all circumstances, for example, in cases where jurisdiction is determined in accordance with any applicable regulations, treaties or other agreements. Matters of jurisdiction and enforcement of judgments as between the United Kingdom and Switzerland and Iceland will be determined in accordance with national law. The Convention for the Reciprocal Recognition and Enforcement of Judgments in Civil Matters 1961 will govern the enforcement of judgments as between the United Kingdom and Norway.

Where any obligations of any person are to be performed or observed in jurisdictions outside England and Wales, or by a person subject to the laws of a jurisdiction outside England and Wales, such obligations may not be enforceable under English law to the extent that the performance or observance thereof would be illegal or contrary to public policy under the laws of any such jurisdiction.

The effectiveness of provisions in the Transaction Agreements and the Notes relating to the choice of English law to govern contractual obligations may not be recognised or upheld by an English court in certain circumstances. For example, the effectiveness of provisions in the Transaction Agreements and the Notes relating to the choice of English law to govern contractual obligations will be subject, where applicable, to Council Regulation (EC) No.593/2008 on the law applicable to contractual obligations as it forms part of domestic law by virtue of the EUWA and the Law Applicable to Contractual Obligations and Non-Contractual Obligations (Amendment etc.) (EU Exit) Regulations 2019 (the “Rome I Regulation”), which provides that, in certain circumstances, the choice of English law to govern contractual obligations may not prejudice or restrict the application of the laws of other jurisdictions.

The effectiveness of provisions in the Transaction Agreements and the Notes relating to the choice of law to govern non-contractual obligations will be subject, where applicable, to Council Regulation (EC) No.864/2007 on the law applicable to non-contractual obligations as it forms part of domestic law by virtue of the EUWA and the Law Applicable to Contractual Obligations and Non-Contractual Obligations (Amendment etc.) (EU Exit) Regulations 2019 (the “Rome II Regulation”), which provides that, in certain circumstances, the choice of English law to govern non-contractual obligations may not prejudice or restrict the application of other laws where such laws are mandatory or cannot be derogated from by contract.

Any provision providing that any calculation, certification, determination, notification, minute or opinion will be conclusive and binding will not be effective if such calculation, certification, determination, notification, minute or opinion is fraudulent or made on an unreasonable or arbitrary basis or in the event of manifest error despite any provision to the contrary and it will not necessarily prevent judicial enquiry into the merits of any claim by any party thereto.

Any provision for the payment of liquidated damages, compensation, additional interest or similar amounts might be held to be unenforceable on the ground that it is a penalty.

Any undertaking or indemnity may be void insofar as it relates to stamp duty payable in the United Kingdom.

An English court may refuse to give effect to any provision of an agreement which amounts to an indemnity in respect of the costs of enforcement or of unsuccessful litigation brought before an English court or where the court has itself made an order for costs.

Certain terms and concepts, although often found in commercial documents, have yet to be clearly defined by the English courts. To the extent that the Transaction Agreements or the Notes contain any such terms or concepts, their meaning will be a matter of construction for an English court.

In the case of agreements that are not required by law to be in writing or evidenced in writing, any provision of an agreement under hand may be amended by oral agreement or waived between the parties or by the conduct of the parties, notwithstanding any provision to the contrary. The most common example of a financing agreement that is required to be evidenced in writing is a guarantee.

If a party to the Transaction Agreements or the Notes is controlled by or otherwise connected with a person or is itself resident in or constituted under the laws of a country which is the subject of United Nations, European Union or United Kingdom sanctions or restrictive measures implemented or effective in the United Kingdom, or is otherwise the target of any such sanctions, then the obligations of the other parties to that party under the Transaction Agreements or the Notes may be unenforceable or void.

Any question as to whether or not any provision of any agreement or instrument which is illegal, invalid, not binding, unenforceable or void may be severed from the other provisions thereof in order to save those other provisions would be determined by an English court in its discretion.

There is some possibility that an English court would hold that a judgment on a particular agreement or instrument, whether given in an English court or elsewhere, would supersede such agreement or instrument to all intents and purposes, so that any obligation thereunder which by its terms would survive such judgment might not be held to do so.

Any person who is not a party to a contract governed by English law may not be able to enforce any provisions of that contract which are expressed to be for the benefit of that person if and to the extent that the Contracts (Rights of Third Parties) Act 1999 has been disapplied.

The effectiveness of terms exculpating (or, as in the case of an indemnity, having the effect of exculpating) a party from a liability or duty otherwise owed or limiting such liability or duty is limited by law.

There is some possibility that an English court having jurisdiction in relation to insolvency law would apply the provisions of Section 426 of the Insolvency Act 1986, as amended, in assisting the courts having the corresponding jurisdiction in any other part of the United Kingdom or any relevant country or territory (as such terms are defined in that section) (in this regard we refer you to Hughes v. Hannover Ruckversicherungs-Aktiengesellschaft [1997] 1 BCLC 497) and, as a result, may, rather than apply insolvency law as it would otherwise apply in England and Wales, apply the insolvency law which is applicable in such other part of the United Kingdom or relevant country or territory in relation to comparable matters.

An English court may refuse to give effect to a claim pursuant to an indemnity or contribution provision in a Transaction Agreement or a Note insofar as the subject matter of such claim relates to penalties imposed under Section 91 of the FSMA or any other relevant provision of the FSMA, the UK Market Abuse Regulation, or the rules made thereunder.

Any provision of an agreement which purports to grant an irrevocable power of attorney or other authorisation or irrevocably appoint a person as agent may nevertheless not be treated by an English court as irrevocable.
