(a) Indemnification of the Underwriters. The Issuer and the Guarantor agree, jointly and severally, to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Issuer or the Guarantor in writing by such Underwriter through the Representative expressly for use therein it being understood and agreed that the only such information consists of the information identified in the Underwriting Agreement as being provided by the Underwriters.

(b) Indemnification of the Issuer and the Guarantor. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Issuer and the Guarantor, their respective directors, their respective officers who signed the Registration Statement and each person, if any, who controls the Issuer or the Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Issuer or the Guarantor in writing by such Underwriter through the Representative expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any Time of Sale Information, it being understood and agreed that the only such information consists of the information identified in the Underwriting Agreement as being provided by the Underwriters.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 7 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 7. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary, (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person, (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representative and any such separate firm for the Issuer, the Guarantor, and its respective directors, its officers who signed the Registration Statement and any control persons of the Issuer or the Guarantor shall be designated in writing by the Issuer. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 90 days after receipt by the Indemnifying Person of such request and (ii) (A) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement or (B) the Indemnifying Person shall not have, on or before the 90th day after the receipt by the Indemnifying Person of such request, disputed in good faith that the fees and expenses claimed by the Indemnified Person are payable by the Indemnifying Person hereunder. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuer and the Guarantor on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Issuer and the Guarantor on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Issuer and the Guarantor on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Issuer and the Guarantor from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Issuer and the Guarantor on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuer and the Guarantor or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Issuer, the Guarantor and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Issuer and the Guarantor, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange, the Nasdaq National Market, the Stock Exchange of Hong Kong Limited or the over the counter market; (ii) trading of any securities issued or guaranteed by the Issuer or the Guarantor shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by U.S. federal, New York State, or Hong Kong authorities; (iv) a material disruption in securities settlement, payment or clearance services in the United States or Hong Kong shall have occurred or (v) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the sole judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

9. Defaulting Underwriter.

(a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Issuer and the Guarantor on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Issuer and the Guarantor shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters, the Issuer or the Guarantor may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Issuer and the Guarantor or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus, the Time of Sale Information or in any other document or arrangement, and the Issuer and the Guarantor agree to promptly prepare any amendment or supplement to the Registration Statement, the Prospectus and the Time of Sale Information that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 to the Underwriting Agreement that, pursuant to this Section 9, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Issuer and the Guarantor as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Issuer and the Guarantor shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Issuer and the Guarantor as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Issuer and the Guarantor shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Issuer and the Guarantor, except that the Issuer and the Guarantor will continue to be liable for the payment of expenses as set forth in Section 10 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Issuer, the Guarantor or any non-defaulting Underwriter for damages caused by its default.

10. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Issuer and the Guarantor will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution (including postage, air freight charges and charges for counting and packaging) of such copies of the materials contained in the Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iii) the costs of preparing, reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Issuer and the Guarantor’s counsel and independent accountants; (v) reasonable fees and expenses of the Underwriters’ counsel; (vi) any stamp, issuance or transfer taxes in connection with the original issuance and sale of the Securities; (vii) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representative may reasonably request and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters); (viii) any fees charged by rating agencies for rating the Securities; (ix) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (x) for any issuance of Securities that are to be listed, the cost of and any incidental expenses relating to listing the Securities on the agreed exchange; all expenses and application fees incurred in connection with the approval of the Securities for book entry transfer by DTC; and (xi) all expenses incurred by the Issuer and the Guarantor in connection with any “road show” presentation to potential investors.

(b) If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Issuer and or Guarantor to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Issuer and the Guarantor shall be unable to perform its obligations under this Agreement, the Issuer and the Guarantor will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering of the Securities contemplated hereby.

11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Underwriter referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

12. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Issuer, the Guarantor and the Underwriters contained in this Agreement or made by or on behalf of the Issuer, the Guarantor or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Issuer, the Guarantor or the Underwriters. The provisions of Section 7 and Section 10 will survive the termination or cancellation of this Agreement.

(d) Amendments or Waivers. No amendment or waiver of any provision of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

(e) Jurisdiction. Each of the Issuer and the Guarantor agrees that any suit, action or proceeding against the Issuer and the Guarantor brought by any Underwriter, the directors, officers, employees and agents of any Underwriter, or by any person who controls any Underwriter, arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any State or United States federal court located in the Borough of Manhattan, the City of New York, New York (each, a “New York court”), and irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding brought in such court and any claim that any such suit, action or proceeding brought in such court has been brought in an inconvenient forum, and irrevocably submits, to the fullest extent permitted by law, to the nonexclusive jurisdiction of such courts in any suit, action or proceeding. Each of the Issuer and the Guarantor hereby appoints the Authorized Agent (as defined in the Underwriting Agreement) upon whom process may be served in any suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated herein that may be instituted in any New York court by any Underwriter, the directors, officers, employees, affiliates and agents of any Underwriter, or by any person who controls any Underwriter, and expressly accepts the non-exclusive jurisdiction of any such court in respect of any such suit, action or proceeding.

Annex C

Form of Opinion of ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇, Hong Kong Solicitors

1. Based solely on the Certificate of Registration (as referred to in Schedule I) of the Guarantor, the Guarantor was incorporated under the Companies Ordinance (Cap. 32 of the Laws of Hong Kong), predecessor to the Companies Ordinance (Cap. 622 of the Laws of Hong Kong) (the “CO”) and remains registered as a limited company in the Companies Register maintained under the CO with corporate power and capacity to own its own properties and conduct its business in accordance with its articles of association.

2. The Guarantor has corporate power and authority to enter into, execute, deliver and perform its obligations under the Underwriting Agreement, the Indenture and the Guarantee (collectively, the “Documents”) and has taken all necessary corporate action to authorize the execution, delivery and performance of its obligations thereunder.

3. The Guarantor has the legal capacity to ▇▇▇ and be sued in its own name under the laws of Hong Kong.

4. The Documents have been duly authorized and executed by the Guarantor.

5. The execution and delivery by the Guarantor of, and the performance by the Guarantor of its obligations under the Documents will not contravene (i) any provision of the statutory laws of Hong Kong that in our experience is normally applicable to general business corporations in relation to transactions of the type contemplated thereby; or (ii) the articles of association of the Guarantor.

6. The execution and delivery by the Issuer of, and the performance by the Issuer of its respective obligations under the Documents and the Notes will not contravene any provision of the statutory laws of Hong Kong that in our experience is normally applicable to general business corporations in relation to transactions of the type contemplated thereby.

7. No consent, approval, authorization, or order of, or qualification or registration or filing with, any governmental body or agency under the laws of Hong Kong applicable to companies generally in relation to transactions of the type contemplated by the Documents is required for the execution and performance by the Guarantor of its obligations under the Documents.

8. The choice of the laws of the State of New York as the proper law to govern the Documents should be upheld as a valid choice of law by the Hong Kong courts, provided that the choice of the laws of the State of New York is bona fide and not for the purpose of avoiding the consequence of the laws of any other jurisdiction and that the application of the laws of the State of New York would not contravene the laws or public policy of Hong Kong.

In particular, a Hong Kong court may not give effect to the choice of the laws of the State of New York applicable to the Documents where (i) all relevant circumstances at the time of choice are connected with a jurisdiction other than the State of New York whose law has been chosen by the parties (in which case the Hong Kong court may apply such rules of law of the connected jurisdiction as may not be derogated from by contract); (ii) there are mandatory rules of Hong Kong law which it must apply regardless of the applicable law chosen by the parties; or (iii) it is bound, in relation to specified proceedings, to apply the law of a different jurisdiction. The choice of a system of law would not be upheld, for example, if it were made with the intention of evading the law of the jurisdiction with which the contract had its most substantial connection and which, in the absence of the relevant system of law, would have invalidated the contract or been inconsistent with it.

9. The submission by the Guarantor to the non-exclusive jurisdiction of any United States federal court and state court located in the Borough of Manhattan, the City of New York, New York (each a “New York Court”) pursuant to the Documents would be recognized by the Hong Kong courts as legal, valid and binding submission to the jurisdiction of the New York Courts if such submission is accepted by such courts and is legal, valid and binding under the laws of the State of New York and any New York Court.

10. As there is no statutory or other arrangement for the reciprocal enforcement of judgments between Hong Kong and the United States, a judgment obtained in the courts of New York cannot be enforced by registration in Hong Kong. Subject to the Foreign Judgments (Restriction on Recognition and Enforcement) Ordinance (Cap 46 of the Laws of Hong Kong) (the “FJO”), a judgment given by the courts of New York against the Guarantor in favor of another party with respect to the Documents could form the basis of a claim in the Hong Kong courts in respect of the judgment debt for which an application for summary judgment could be made without re-examination or re-litigation of the matters adjudicated on if:

(a) recognition and/ or enforcement is not restricted by operation of the provision of the FJO;

(b) the judgment was not obtained by fraud, misrepresentation or mistake nor obtained in proceedings which contravene the rules of natural justice;

(d) the relevant court in New York had jurisdiction in accordance with the Hong Kong rules on the conflict of laws;

(e) the judgment is for a definite sum of money which is not payable in respect of taxes or other charges of a similar nature or in respect of a fine or other penalty; and

(f) the judgment is final and conclusive between the parties, but if it is capable of being appealed or an appeal is pending, the proceedings in Hong Kong are likely to be stayed by the courts of Hong Kong pending any such appeal being heard.

11. No stamp duty or similar documentary tax is payable in Hong Kong in connection with the issue and offering of the Notes upon the execution and delivery of the Documents by the Guarantor.

12. No deduction or withholding for or on account of Hong Kong taxes will be required to be made by the Underwriters to any tax authority in Hong Kong from any payment due from them in connection with (i) the issue, sale and delivery by the Issuer of the Notes to, or for the account of, the Underwriters; or (ii) the sale and delivery by the Underwriters of the Notes to any subsequent purchasers thereof. It should nevertheless be noted that any sum that may accrue to or be received by any of the Underwriters in respect of the sale and delivery by such Underwriter of any Note or Notes to any subsequent purchaser may, unless the sale of such Note or Notes is a sale of a capital asset, have to be brought into charge to profits tax in Hong Kong if it is a receipt of or accrual to a trade or business carried on in Hong Kong by such Underwriter and is a receipt or accrual which arises in or is derived from Hong Kong.

13. No deductions or withholdings for or on account of any Hong Kong taxes will be required to be made by the Guarantor to any tax authority in Hong Kong from any payment due from it under the Documents.

14. The offering of the Notes by the Issuer in Hong Kong in accordance with the Prospectus Supplement under the caption “Underwriting - Sales Outside the United States - Notice to Prospective Investors in Hong Kong” will not render the Basic Prospectus or the Prospectus Supplement a prospectus to which the requirements of the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32 of the Laws of Hong Kong) will apply.

15. The issue, or possession for the purposes of issue, whether in Hong Kong or elsewhere, of an advertisement, invitation or document relating to the Securities will not contravene Section 103(1) of the Securities and Futures Ordinance (Cap. 571 of the Laws of Hong Kong) (the “SFO”).

16. The statements included in the Prospectus Supplement under the captions “Taxation—Hong Kong” and “Underwriting—Sales Outside the United States—Notice to Prospective Investors in Hong Kong”, and in the Basic Prospectus under the caption “Enforceability of Civil Liabilities” and “Part II—Information not required in Prospectus—Item 8—Indemnification of Directors and Officers” as they purport to describe provisions of Hong Kong law or legal conclusions with respect thereto, in our opinion fairly and accurately summarize the matters referred to therein in all material respects.

17. Based on the letter dated , 2018 from The Stock Exchange of Hong Kong Limited (the “Stock Exchange”) as referred to in Schedule I, the approval for the listing of and permission to deal in the Notes has been granted in principle by the Stock Exchange, subject to the fulfilment of certain conditions set out in such letter.

18. The payment obligations of the Guarantor under the Guarantee (assuming that such obligations are enforceable under the laws of the State of New York and such obligations are unsecured and unsubordinated) will, in an insolvency, rank at least pari passu in priority of payment with the other unsecured and unsubordinated payment obligations of the Guarantor, except to the extent that such other obligations are preferred solely by operation of law.
