Any reference herein to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3, which were filed under the Exchange Act on or before the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act after

1. Representations and Warranties. The Issuer and the Guarantors, where applicable, represent and warrant to, and agree with, each Underwriter as set forth below in this Section 1 (save that the representation, warranty and undertaking given in clause (gg) below shall not be made in so far as it would result in a violation of, or conflict with, Council Regulation (EC) 2271/96 or, with respect to Deutsche Bank AG, London Branch and UniCredit Bank AG only, Section 7 of the German Foreign Trade Regulation (Außenwirtschaftsverordnung)).

(a) The Companies meet the requirements for use of Form S-3 under the Act and have prepared and filed with the Commission an automatic shelf registration statement, as defined in Rule 405 (the file number of which is set forth in Schedule I hereto) on Form S-3, including a related Base Prospectus, for registration under the Act of the offering and sale of the Securities. Such Registration Statement, including any amendments thereto filed prior to the Execution Time, became effective upon filing and no notice of objection of the Commission to the use of such registration statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Act has been received by any Company. No order suspending the effectiveness of the Registration Statement has been issued by the Commission and no proceeding for that purpose or pursuant to Section 8A of the Act against any of the Companies or related to the offering has been initiated or threatened by the Commission. The Companies may have filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more preliminary prospectus supplements relating to the Securities, each of which has previously been furnished to you. The Companies will file with the Commission a final prospectus supplement relating to the Securities in accordance with Rule 424(b). As filed, such final prospectus supplement shall contain, in all material respects, all information required by the Act and the rules thereunder, and, except to the extent the Representatives shall agree to a modification, shall be in all substantive respects in the form furnished to you prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in the Base Prospectus and any Preliminary Prospectus) as OGI has advised you, prior to the Execution Time, will be included or made therein. The Registration Statement, at the Execution Time, meets the requirements set forth in Rule 415(a)(1)(x). The initial Effective Date of the Registration Statement was not earlier than the date three years before the Execution Time.

(b) On each Effective Date, the Registration Statement did, at the time of filing of each Preliminary Prospectus such Preliminary Prospectus did, and when the Final Prospectus is first filed in accordance with Rule 424(b) and on the Closing Date, the Final Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the Act, the Exchange Act and the Trust Indenture Act and the respective rules thereunder; on each Effective Date and at the Execution Time, the Registration Statement did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to

make the statements therein not misleading; on the Effective Date and on the Closing Date, the Indenture did or will comply in all material respects with the applicable requirements of the Trust Indenture Act and the rules thereunder; at the time of filing of each Preliminary Prospectus, such Preliminary Prospectus did not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and on the date of any filing pursuant to Rule 424(b) and on the Closing Date, the Final Prospectus (together with any supplement thereto) will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that none of the Companies makes any representations or warranties as to (i) those parts of the Registration Statement which shall constitute the Statements of Eligibility (Form T-1) under the Trust Indenture Act of the Trustee or (ii) the information contained in or omitted from the Registration Statement, any Preliminary Prospectus or the Final Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to OGI by or on behalf of any Underwriter through the Representatives specifically for inclusion in the Registration Statement, any Preliminary Prospectus or the Final Prospectus (or any supplement thereto), it being understood and agreed that the only such information furnished by or on behalf of any Underwriters consists of the information described as such in Section 8 hereof.

(c) The documents incorporated by reference in the Registration Statement, the Final Prospectus and the Disclosure Package, when they were filed with the Commission, conformed in all material respects with the applicable provisions of the Exchange Act and none of such documents contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and any further documents so filed and incorporated by reference in the Registration Statement, the Final Prospectus or the Disclosure Package, when such documents become effective or are filed with the Commission, as the case may be, will conform in all material respects to the requirements of the Act or the Exchange Act, as applicable, and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) (i) The Disclosure Package and (ii) each electronic roadshow identified on Schedule V hereto, when taken together as a whole with the Disclosure Package, does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Companies by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8 hereof.

(e) (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at the time any Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on the exemption in Rule 163, and (iv) at the Execution Time (with such date being used as the determination date for purposes of this clause (iv)), each Company was or is (as the case may be) a “well-known seasoned issuer” as defined in Rule 405. The Companies agree to pay the fees required by the Commission relating to the Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

(f) (i) At the earliest time after the filing of the Registration Statement that the Issuer or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of the Securities and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), each of the Companies was not and is not an Ineligible Issuer (as defined in Rule 405), without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that any such Company be considered an Ineligible Issuer.

(g) Each Issuer Free Writing Prospectus, including the final term sheet prepared and filed pursuant to Section 5(b) hereof, does not include any information that conflicts with the information contained in the Registration Statement, including any document incorporated therein and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Companies by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8 hereof.

(s) No Company is in violation of its charter, by-laws or other organizational documents; and no Subsidiary of OGI is in violation of its charter, by-laws or other organizational documents except for such violations that would not result in a Material Adverse Effect. Neither OGI nor any of its Subsidiaries is in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which OGI or any of its Subsidiaries is a party or by which it may be bound or to which any of the property or assets of OGI or any of its Subsidiaries may be subject (collectively, “Agreements and Instruments”), except for such defaults or violations that would not result in a Material Adverse Effect; and the execution, delivery and performance of this Agreement, the Indenture and the Securities and any other agreement or instrument entered into or issued or to be entered into or issued by the Companies in connection with the transactions contemplated hereby or thereby or in the Disclosure Package and the Final Prospectus and the consummation of the transactions contemplated herein and in the Disclosure Package and the Final Prospectus (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the Disclosure Package and the Final Prospectus under the caption “Use of Proceeds”) and compliance by the Companies with their respective obligations hereunder have been duly authorized by all necessary corporate action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or a Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of OGI or any of its Subsidiaries pursuant to, the Agreements and Instruments except for such conflicts, breaches or defaults or Repayment Events, liens, charges or encumbrances that, individually or in the aggregate, would not result in a Material Adverse Effect, nor will such action result in any violation of (x) the provisions of the charter, by-laws or other organizational documents of the Companies; (y) the charter, by-laws or other organizational documents of the Subsidiaries of OGI or (z) any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over OGI or any of its Subsidiaries or any of their assets, properties or operations except (in the case of (y) and (z) only) as would not have a Material Adverse Effect. As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting

on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by OGI or any of its Subsidiaries.

(t) No labor dispute with the employees of OGI or any of its Subsidiaries exists or, to the knowledge of OGI, is imminent, and OGI is not aware of any existing or imminent labor disturbance by the employees of any of its or any of its Subsidiaries’ principal suppliers, customers or contractors, which, in any such case, may reasonably be expected to result in a Material Adverse Effect.

The aggregate of all pending legal or governmental proceedings to which OGI or any of its Subsidiaries is a party or of which any of their respective property or assets is the subject which are not described in the Disclosure Package and the Final Prospectus, including ordinary routine litigation incidental to the business, could not reasonably be expected to result in a Material Adverse Effect.

(v) OGI and its Subsidiaries own or possess, or can acquire on reasonable terms adequate patents, patent rights, licenses, inventions, copyrights, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures) trademarks, service marks, trade names or other intellectual property (collectively, “Intellectual Property”) necessary to continue to carry on the business now operated by them in all material respects, and neither OGI nor any of its Subsidiaries has received any notice or is otherwise aware of any infringement of or conflict with asserted rights of others with respect to any Intellectual Property or of any facts or circumstances which would render any Intellectual Property invalid or inadequate to protect the interest of OGI or any of its Subsidiaries therein except for such of the foregoing as would not result in a Material Adverse Effect.

(w) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency is necessary or required for the performance by the Companies of their respective obligations hereunder in connection with the offering, issuance or sale of the Securities hereunder or the consummation of the transactions contemplated by this Agreement or for the due execution, delivery or performance of this Agreement, the Base Indenture and the Supplemental Indenture by the Companies, except (i) such as have been already obtained or (ii) such as may be required by the securities or blue sky laws of the various states in connection with the purchase and distribution of the Securities by the Underwriters in the manner contemplated herein and in the Final Prospectus.

(y) OGI and each of its Subsidiaries have good and marketable title to all real property owned by OGI and such Subsidiary and good title to all other properties owned by them, in each case, free and clear of all mortgages, pledges, liens, security interests, claims, restrictions or encumbrances of any kind except such as (a) are described in the Disclosure Package and the Final Prospectus or (b) would not, individually or in the aggregate, have a Material Adverse Effect, and all of the leases and subleases material to the business of OGI and its Subsidiaries, considered as one enterprise, and under which OGI or any of its Subsidiaries holds properties described in the Disclosure Package and the Final Prospectus, are in full force and effect, and neither OGI nor any of its Subsidiaries has any notice of any material claim of any sort that has been asserted by anyone adverse to the rights of OGI or any of its Subsidiaries under any of the leases or subleases mentioned above, or affecting or questioning the rights of OGI or any of its Subsidiaries to the continued possession of the leased or subleased premises under any such lease or sublease, except for such of the foregoing as would not have a Material Adverse Effect.

(z) OGI maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with U.S. GAAP and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

required disclosure. OGI and its Subsidiaries, taken as a whole, have carried out evaluations of the effectiveness of their disclosure controls and procedures as required by Rule 13a-15 of the Exchange Act.

(bb) Except as described in the Disclosure Package and the Final Prospectus and except such matters as would not, individually or in the aggregate, result in a Material Adverse Effect, (A) neither OGI nor any of its Subsidiaries is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”), (B) OGI and its Subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with their requirements, (C) there are no pending, or to the knowledge of OGI, threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against OGI or any of its Subsidiaries and (D) to the knowledge of OGI, there are no events or circumstances that might reasonably be expected to form the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency, against or affecting OGI or any of its Subsidiaries relating to Hazardous Materials or Environmental Laws.

Any certificate signed by any officer of any of the Companies and delivered to the Representatives or counsel for the Underwriters in connection with the offering of the Securities shall be deemed a representation and warranty by the Companies, as to matters covered thereby, to each Underwriter.

2. Purchase and Sale. Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Issuer agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Issuer, at the purchase price set forth in Schedule I hereto the principal amount of each series of the Securities set forth opposite such Underwriter’s name in Schedule II hereto.

3. Delivery and Payment. Delivery of and payment for the Securities shall be made on the date and at the time specified in Schedule I hereto or at such time on such later date not more than three Business Days after the foregoing date as the Representatives shall designate, which date and time may be postponed by agreement between the Representatives and the Issuer or as provided in Section 9 hereof (such date and time of delivery and payment for the Securities being herein called the “Closing Date”). Delivery of the Securities shall be made to the Representatives for the respective accounts of the several Underwriters against payment by the several Underwriters through the Representatives of the purchase price thereof to or upon the

order of the Issuer by wire transfer payable in same-day funds to an account specified by the Issuer. Each series of the Securities will be delivered by the Issuer in the form of one or more global notes (the “Global Notes”), duly executed and registered in the name of BT Globenet Nominees Limited, with any transfer taxes payable in connection with the sale of the Securities duly paid by the Companies.

(“Euroclear”) and Clearstream Banking, société anonyme, Luxembourg (“Clearstream, Luxembourg”) unless the Representatives shall otherwise instruct. It is understood that the Common Depositary has been authorized by the Representatives, for their own accounts and the accounts of the several Underwriters, to accept delivery of and receipt for, and make payment of the purchase price for, the Securities.

4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Securities for sale to the public as set forth in the Final Prospectus.

5. Agreements. Each of the Companies agrees with the several Underwriters that:

(a) Prior to the termination of the offering of the Securities, none of the Companies will file any amendment of the Registration Statement or supplement (including the Final Prospectus or any Preliminary Prospectus) to the Base Prospectus unless OGI has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. The Companies will cause the Final Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Representatives with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representatives of such timely filing. OGI will promptly advise the Representatives: (1) when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b), (2) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (3) of any request by the Commission or its staff for any amendment of the Registration Statement or for any supplement to the Final Prospectus or for any additional information, (4) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (5) of the receipt by any of the Companies of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. Each of the Companies will use its reasonable best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its reasonable best efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) To prepare a final term sheet, containing solely a description of final terms the Securities, in the form attached as Schedule IV hereto, and to file such term sheet pursuant to Rule 433(d) within the time required by such Rule.

(c) If, at any time prior to the filing of a final prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made at such time, not misleading, OGI will (i) notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

(d) If, at any time when the Final Prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Final Prospectus, as then supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made at such time, not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Final Prospectus, OGI promptly will (i) notify the Representatives of such event, (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its reasonable best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Final Prospectus and (iv) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request.

(e) As soon as practicable, OGI will make generally available to its security holders and to the Representatives, an earnings statement or statements (which need not be audited) of OGI and its Subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158.

(f) The Companies will furnish to each of the Representatives and counsel for the Underwriters, without charge, one signed copy of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Representatives may reasonably request.

(g) The Companies will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may designate, will maintain such qualifications in effect so long as required for the distribution of the Securities and will pay any fee of the Financial Industry Regulatory Authority in connection with its review of the offering; provided that in no event shall any of the Companies be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that (i) would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, or (ii) would subject it to payment of taxes, in any jurisdiction where it is not now so subject.

(h) The Companies agree that, unless they have obtained or will obtain the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Companies that, unless it has obtained or will obtain, as the case may be, the prior written consent of OGI, each of them has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Companies with the Commission or retained by the Companies under Rule 433, other than a free writing prospectus containing the information contained in the final term sheet prepared and filed pursuant to Section 5(b) hereof; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule III and Schedule V hereto. Any such free writing prospectus consented to by the Representatives or OGI is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Companies agree that (x) they have treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) they have complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(i) The Companies will not, without the prior written consent of the Representatives, offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Companies or any affiliate of the Companies or any person in privity with the Companies or any affiliate of the Companies), directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any debt securities issued or guaranteed by the Companies (other than the Securities) or publicly announce an intention to effect any such transaction, until the Business Day set forth on Schedule I hereto.

(j) The Companies will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Companies to facilitate the sale or resale of the Securities. The Companies have not issued nor will issue, without the prior consent of the Underwriters, any stabilization

announcement referring to the proposed issue of Securities. Each of the Companies authorizes the Underwriters to make such public disclosure of information relating to stabilization of the Securities as is required by applicable law, regulation and guidance.

(k) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Companies will pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Disclosure Package and the Final Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing this Agreement, the Indenture and the Securities; (iv) the fees and expenses of the Companies’ counsel and independent accountants; (v) 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 Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the reasonable related fees and expenses of counsel for the Underwriters); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee, any paying agent, any transfer agent and any registrar (including related fees and expenses of any counsel to such parties) and all fees and expenses (including fees and expenses of counsel) in connection with clearance and settlement of the Securities by “book-entry” transfer with the Common Depositary for Euroclear and Clearstream, Luxembourg; (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the Financial Industry Regulatory Authority; (ix) the fees and expenses incurred in connection with the listing of the Securities on The New York Stock Exchange (the “NYSE”); (x) any stamp or other duties or taxes (including any interest and penalties) on or in connection with the issue and delivery of the Securities, the purchase by the Underwriters of the Securities, the sale and delivery of the Securities by the Underwriters to the initial purchasers thereof and the execution and delivery of this Agreement, the Indenture and the Guarantees and any value added tax payable in connection with the commissions or other amounts payable or allowed under this Agreement and otherwise in connection with the transactions envisaged by this Agreement; and (xi) all expenses incurred by the Companies in connection with any “road show” presentation to potential investors.

(l) The Companies shall use commercially reasonable efforts to have the Securities listed and admitted to trading on the NYSE or another “recognised stock exchange” (as defined in Section 1005 of the United Kingdom Income Tax Act 2007) upon issuance of the Securities or as promptly as practicable thereafter.

(m) The Companies shall cooperate with the Representatives and use their commercially reasonable efforts in arranging for the Securities to be eligible for clearance and settlement through Clearstream, Luxembourg and Euroclear.

(n) The Companies agree with each of the Underwriters that all payments under this Agreement shall be made free and clear of, and without withholding or deduction for or on account of any present or future taxes, duties, levies, imposts, assessments or governmental charges of whatever nature imposed or levied by or on behalf of any Taxing Jurisdiction (“Taxes”), unless any of the Companies is required by law to so withhold or deduct any amount for or on account of any Taxes from any payment made hereunder. In that event, any such Company shall pay such additional amounts as may be necessary in order that the net amounts received after such withholding or deduction will equal the amount that would have been received if no withholding or deduction has been made, except to the extent that such Taxes (a) were imposed due to any present or former connection of an Underwriter with the Taxing Jurisdiction other than (i) a jurisdiction where the persons entitled to payment are incorporated or (ii) any connection arising solely from the entering into of this Agreement or receipt of payments hereunder or (b) would not have been imposed but for the failure of such Underwriter to comply with any reasonable certification, identification or other reporting requirements concerning the nationality, residence, identity or connection with the Taxing Jurisdiction of the Underwriter if such compliance is required or imposed by law as a precondition to an exemption from, or reduction in, such taxes, duties or other charges.

(o) All amounts payable by the Companies under this Agreement shall be exclusive of value added tax and any similar Tax (“VAT”). If VAT is chargeable on any supply under this Agreement (for which an Underwriter or its affiliate is liable to account to a Tax authority), the Companies will pay to the relevant Underwriter an amount equal to such VAT (against delivery of an appropriate VAT invoice). Where any Company is required under this Agreement to reimburse or indemnify any Underwriter for or against any cost or expense, the amount of such cost or expense shall include all amounts representing VAT on such cost or expense save to the extent that the relevant Underwriter determines (in its sole discretion exercised in good faith) the relevant VAT is recoverable.

6. Conditions to the Obligations of the Underwriters. The obligations of the Underwriters to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Companies contained herein as of the Execution Time and the Closing Date, to the accuracy of the statements of the Companies made in any certificates pursuant to the provisions hereof, to the performance by the Companies of their obligations hereunder and to the following additional conditions:

(f) The Companies shall have furnished to the Representatives a certificate of the Companies, signed by an Executive Vice President, or, in the case of the Issuer and OCI only, a director, and the principal financial or accounting officer of each of the Companies, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Registration Statement, the Final Prospectus, the Disclosure Package and any supplements or amendments thereto, as well as each electronic roadshow used to offer the Securities identified on Schedule V and this Agreement and that:

(i) the representations and warranties of the Companies in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Companies have complied with all the agreements and satisfied all the conditions on their part to be performed or satisfied at or prior to the Closing Date;

(ii) no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or, to any of the Companies’ knowledge, threatened; and

(g) OGI shall have requested and caused KPMG LLP to have furnished to the Representatives, at the Execution Time and at the Closing Date, letters (which may refer to letters previously delivered to one or more of the Representatives), dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representatives, confirming that they are independent accountants within the meaning of the Act and the applicable rules and regulations thereunder adopted by the Commission and the PCAOB and containing statements and information of the type customarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained or incorporated by reference in the Registration Statement, the Disclosure Package and the Final Prospectus; provided that the letter delivered on the Closing Date shall use a “cut-off” date no more than three business days prior to the Closing Date.

(i) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the Companies’ debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Section 3(a)(62) under the Exchange Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

7. Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Companies to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Companies will, jointly and severally, reimburse the Underwriters severally through Barclays Bank PLC on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

8. Indemnification and Contribution. (a) The Companies agree, jointly and severally, to indemnify and hold harmless each Underwriter, the directors, officers, employees, affiliates and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Final Prospectus or any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 5(b) hereto, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Companies will not be liable in any such case to the extent that any such loss, claim, damage or liability

arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Companies by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Companies may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Companies, each of their respective directors, each of their respective officers who signs the Registration Statement, and each person who controls the Companies within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Companies to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Companies by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Companies acknowledge that the statements set forth in the last paragraph of the cover page regarding delivery of the Securities and, under the heading “Underwriting,” (i) in the first paragraph, the list of Underwriters and their respective participation in the sale of the Securities, and (ii) the fifth paragraph related to stabilization in any Preliminary Prospectus and the Final Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus or the Final Prospectus.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to

those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include an admission of fault.

(d) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Companies and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Companies and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Companies on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall (i) any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Companies and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Companies on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Companies shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by them collectively, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Companies on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Companies and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d),

no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Companies within the meaning of either the Act or the Exchange Act, each officer of the Companies who shall have signed the Registration Statement and each director of the Companies shall have the same rights to contribution as the Companies, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule II hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Companies. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Companies and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Companies prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in OGI’s common stock shall have been suspended by the Commission or the NYSE or trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such Exchange, (ii) a banking moratorium shall have been declared either by U.S. Federal, New York State, Delaware State, United Kingdom or European Union authorities, (iii) there shall have occurred a material disruption in securities settlement or clearance services in the United States or with respect to the Euroclear or Clearstream, Luxembourg systems in Europe or (iv) there shall have occurred any outbreak or escalation of hostilities nationally or internationally involving the United States, the United Kingdom or the European Union, declaration by the United States, the United Kingdom or the European Union of a national emergency or war, or other calamity or crisis the effect of which on the United States or international financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as

contemplated by any Preliminary Prospectus or the Final Prospectus (exclusive of any amendment or supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Companies or their officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Companies or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 5(k), 7, 8 and 16 hereof shall survive the termination or cancellation of this Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to Barclays Bank PLC, 5 The North Colonnade, Canary Wharf, ▇▇▇▇▇▇ ▇▇▇ ▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, Attention: Debt Syndicate (tel: ▇▇▇ (▇)▇▇ ▇▇▇▇ ▇▇▇▇, fax: ▇▇▇ (▇)▇▇ ▇▇▇▇ ▇▇▇▇); BNP Paribas, ▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇ ▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, Attention: Fixed Income Syndicate (fax: ▇▇▇ (▇)▇▇ ▇▇▇▇ ▇▇▇▇); Deutsche Bank AG, London Branch, Winchester House, 1 Great ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, Attention: Syndicate Desk (tel: ▇▇▇ (▇)▇▇ ▇▇▇▇ ▇▇▇▇, fax: ▇▇▇ (▇)▇▇ ▇▇▇▇ ▇▇▇▇); ▇.▇. ▇▇▇▇▇▇ Securities plc at ▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇ ▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, Attention: Head of Debt Syndicate and Head of EMEA Debt Capital Markets Group (fax: ▇▇▇ (▇)▇▇ ▇▇▇▇ ▇▇▇▇), or, if sent to the Companies, will be mailed, delivered or telefaxed to ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ (fax: ▇▇ ▇▇▇-▇▇▇-▇▇▇▇), attention of the Legal Department, and confirmed to it at ▇▇▇▇▇ Day, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ (fax: ▇▇ ▇▇▇-▇▇▇-▇▇▇▇), Attention: ▇▇▇▇ ▇. ▇▇▇▇.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

14. No Fiduciary Duty. The Companies hereby acknowledge that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Companies, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Companies and (c) the Companies’ engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Companies agree that they are solely responsible for making their own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Companies on related or other matters). The Companies agree that they will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Companies, in connection with such transaction or the process leading thereto.

15. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Companies and the Underwriters, or any of them, with respect to the subject matter hereof.

16. Applicable Law. (a) This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

(b) By the execution and delivery of this Agreement, (i) the Issuer hereby irrevocably designates and appoints OGI (together with any successor, the “Agent for Service”), as its authorized agent upon which process may be served in any suit or proceeding based on or arising out of this Agreement or the Securities, that may be instituted in any U.S. federal or state court in the Borough of Manhattan in the City of New York, County and State of New York, or brought under U.S. federal or state securities laws, (ii) OGI hereby accepts the appointment as Agent for Service made by the Issuer in clause (i) above, (iii) the Issuer submits to the jurisdiction of any such court in any such suit or proceeding, and (iv) the Issuer agrees that service of process upon the Agent for Service shall be deemed in every respect effective service of process upon the Issuer in any such suit or proceeding. The Issuer further agrees to take any and all action, including the execution and filing of any and all such documents and instruments, as may be necessary to continue such designation and appointment of the Agent for Service in full force and effect so long as any of the Securities shall be outstanding.

17. Waiver of Jury Trial. The Companies hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

18. Agreement Among Underwriters. The execution of this Agreement by each Underwriter constitutes the acceptance of each Underwriter of the ICMA Agreement Among Managers Version 1/New York Schedule (the “AAM”), subject to any amendment notified to the Underwriters in writing at any time prior to the execution of this Agreement. References to the “Managers” shall be deemed to refer to the Underwriters, references to the “Lead Managers” shall be deemed to refer to each of the Representatives, references to “Settlement Lead Manager” shall be deemed to refer to Barclays Bank PLC and references to “Subscription Agreement” shall be deemed to refer to this Agreement. As applicable to the Underwriters, Clause 3 of the AAM shall be deemed to be deleted in its entirety and replaced with Section 9 of this Agreement.

Each Underwriter agrees severally to pay the portion of the aggregate expenses of the Underwriters represented by such Underwriter’s pro rata share (based on the proportion that the principal amount of Securities set forth opposite each Underwriter’s name in Schedule II bears to the aggregate principal amount of Securities set forth opposite the names of all Underwriters) of the Securities (with respect to each Underwriter, the “Pro Rata Expenses”). Notwithstanding anything contained in the International Capital Markets Association Primary Market Handbook, each Underwriter hereby agrees that the Settlement Lead Manager (as defined in this Section 18) may allocate the Pro Rata Expenses to the account of such Underwriter for settlement of accounts (including payment of such Underwriter’s fees by the

Settlement Lead Manager) as soon as practicable but in any case no later than 90 days following the Closing Date.

Where there are any inconsistencies between this Agreement and the AAM, the terms of this Agreement shall prevail. For the avoidance of doubt, this Section 18 purely governs the relationship among the Underwriters and does not affect the relationship in this Agreement between the Companies on one hand and any of the Underwriters on the other hand.

19. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement.

20. Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than the Agreement Currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase the Agreement Currency with such other currency in New York City on the business day preceding that on which final judgment is given. The obligations of the Companies in respect of any sum due from them to the Underwriters shall, notwithstanding any judgment in any currency other than the Agreement Currency, not be discharged until the first Business Day, following receipt by the Underwriters of any sum adjudged to be so due in such other currency, on which (and only to the extent that) the Underwriters may in accordance with normal banking procedures purchase the Agreement Currency with such other currency; if the amount of the Agreement Currency so purchased is less than the sum originally due to the Underwriters hereunder, each Company agrees (on joint and several basis), as a separate obligation and notwithstanding any such judgment, to indemnify the Underwriters against such loss. If the amount of the Agreement Currency so purchased is greater than the sum originally due to the Underwriters hereunder, each of the Underwriters severally and not jointly agrees to pay to the Companies (but without duplication) an amount equal to the excess of the amount of the Agreement Currency so purchased over the sum originally due to any such Underwriter hereunder.

21. Contractual Recognition of Bail-In. Notwithstanding and to the exclusion of any other term of this Agreement or any other agreements, arrangements, or understanding between the Companies and the Underwriters, each Company acknowledges and accepts that a BRRD Liability arising under this Agreement may be subject to the exercise of Bail-in Powers by the Relevant Resolution Authority, and acknowledges, accepts, and agrees to be bound by:

(a) the effect of the exercise of Bail-in Powers by the Relevant Resolution Authority in relation to any BRRD Liability of an Underwriter to the Companies under this Agreement, that (without limitation) may include and result in any of the following, or some combination thereof:

(i) the reduction of all, or a portion, of the BRRD Liability or outstanding amounts due thereon;

(ii) the conversion of all, or a portion, of the BRRD Liability into shares, other securities or other obligations of such Underwriter or another person, and the issue to or conferral on the Companies of such shares, securities or obligations;

(iii) the cancellation of the BRRD Liability; or

(iv) the amendment or alteration of any interest, if applicable, thereon, the maturity or the dates on which any payments are due, including by suspending payment for a temporary period; and

(b) the variation of the terms of this Agreement, as deemed necessary by the Relevant Resolution Authority, to give effect to the exercise of Bail-in Powers by the Relevant Resolution Authority.

The terms which follow, when used in this Section 21, shall have the meanings indicated.

(i) each of the Representatives (each a “Manufacturer” and together the “Manufacturers”) acknowledges to each other Manufacturer that it understands the responsibilities conferred upon it under the Product Governance Rules relating to each of the product approval process, the target market and the proposed distribution channels as

applying to the Securities and the related information set out in the Registration Statement, any Preliminary Prospectus, the Disclosure Package or the Final Prospectus or any such amendment or supplement, in connection with the Securities; and

23. Stabilization. In connection with the issue of the Securities, Barclays Bank PLC (in this capacity, the “Stabilizing Manager”) (or any person acting on its behalf), may over-allot Securities or effect transactions with a view to supporting the market price of the Securities during the stabilization period at a level higher than that which might otherwise prevail. However, there is no assurance that the Stabilizing Manager (or persons acting on behalf of the Stabilizing Manager) will undertake any stabilizing action. Nothing contained in this Section 23 shall be construed so as to require the Issuer to issue in excess of the aggregate principal amount of Securities specified in Schedule II hereto. Such stabilization, if commenced, may be discontinued at any time and shall be conducted by the Stabilizing Manager in accordance with all applicable laws and directives.

24. Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), certain of the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Companies, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

25. Recognition of the U.S. Special Resolution Regimes. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.
