TRANSACTION AGREEMENT

This TRANSACTION AGREEMENT, dated as of March 31, 2026 (this “Agreement”), is entered into by and among Eli Lilly and Company, an Indiana corporation (“Parent”), LDH XV Corporation, a Delaware corporation and direct wholly owned Subsidiary of Parent (“Purchaser”), and Centessa Pharmaceuticals plc, a public limited company registered in England and Wales (the “Company” and, together with Parent and Purchaser, the “Parties”).

WHEREAS, the Parties intend that the entire issued and to be issued share capital of the Company be acquired by Purchaser (or, at Parent’s election (i) in respect of any or all of the Remnant Shares, its nominee(s) and (ii) in respect of the Depositary Shares, the DR Nominee) by means of the Scheme of Arrangement on the terms and subject to the conditions set out in this Agreement;

WHEREAS, the board of directors of the Company (the “Company Board”) has resolved (i) that this Agreement, the Scheme of Arrangement, the Contemplated Transactions, the Voting and Support Agreements and the other transactions contemplated hereby and thereby are in the best interests of the Company and would promote the success of the Company for the benefit of the Company’s Shareholders as a whole, (ii) that the execution, delivery and performance by the Company of its covenants and obligations contained in this Agreement and the Scheme of Arrangement and the consummation of the Contemplated Transactions, be and are approved and (iii) to recommend to the Company Shareholders the approval of the Scheme of Arrangement at the Scheme Meeting and the passing of the Company Shareholder Resolution at the Company GM;

WHEREAS, the boards of directors of Parent and Purchaser have, on the terms and subject to the conditions set forth herein, adopted this Agreement and approved the Contemplated Transactions;

WHEREAS, concurrently with the execution and delivery of this Agreement, and as a condition and inducement to Parent’s and Purchaser’s willingness to enter into this Agreement, certain of the Company’s Shareholders have entered into irrevocable undertakings to vote (or, where applicable, cause to vote) in favor of all resolutions relating to the approval of the Scheme of Arrangement at the Scheme Meeting and the Company Shareholder Resolution at the Company GM (collectively, the “Voting and Support Agreements”); and

WHEREAS, subject to the terms and conditions of this Agreement, at or prior to the Effective Time, Parent, Purchaser and an agent selected by Parent and reasonably acceptable to the Company (the “Rights Agent”) shall enter into a Contingent Value Rights Agreement in substantially the form attached hereto as Annex I (the “CVR Agreement”).

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, Parent, Purchaser and the Company hereby agree as follows:

ARTICLE I

THE CONTEMPLATED TRANSACTIONS

Section 1.1. The Contemplated Transactions. At the Effective Time, upon the terms and subject to the conditions set forth in this Agreement, Purchaser (or, at Parent’s election (a) in respect of any or all of the Remnant Shares, its nominee(s) and (b) in respect of the Depositary Shares, the DR Nominee) shall acquire the Scheme Shares pursuant to the Scheme of Arrangement. The Scheme Shares will be acquired fully paid, with full title guarantee, free and clear of all Liens (other than transfer restrictions arising under applicable securities Laws) and together with all rights at the Effective Time or thereafter attached or relating thereto, including voting rights and the right to receive and retain all dividends and other distributions (if any) and any other return of capital (whether by way of reduction of share capital or share premium account or otherwise) thereon.

Section 1.2. Closing. Subject to the provisions of this Agreement, the closing of the Contemplated Transactions (the “Closing”) will take place remotely by exchange of documents and signatures (or their electronic counterparts), as promptly as practicable (and in any event within two (2) Business Days) after the satisfaction or (to the extent permitted by Law) waiver of the conditions set forth in Article VII (excluding conditions that, by their terms, cannot be satisfied until the Closing, but subject to the satisfaction or (to the extent permitted by Law) waiver of such conditions at the Closing), or at such other place or on such other date as Parent and the Company may mutually agree (the date on which the Closing actually occurs, the “Closing Date”).

Section 1.3. Delivery of Court Order. On the Closing Date, in connection with the Closing, the Company shall (a) deliver, or cause to be delivered, the Court Order to the Registrar of Companies in England and Wales and the Scheme of Arrangement shall become effective upon such delivery in accordance with its terms (the date and time of such delivery being the time that the Scheme of Arrangement shall become effective, herein referred to as the “Effective Time”) and (b) deliver a copy of the Court Order to Parent together with appropriate evidence of the Effective Time as soon as practicable following the making of the Court Order.

ARTICLE II

TRANSFER OF SCHEME SHARES

Section 2.1. Transfer of Scheme Shares.

(a) At the Effective Time, the Scheme Shares (including, for the avoidance of doubt, the Depositary Shares) shall be transferred from the Scheme Shareholders to Purchaser (or, at Parent’s election (i) in respect of any or all of the Remnant Shares, its nominee(s) and (ii) in respect of the Depositary Shares, the DR Nominee) in accordance with the provisions of this Agreement and the Scheme of Arrangement (and without any action by the Scheme Shareholders), and the Scheme Shareholders shall cease to have any rights with respect to the Scheme Shares, except their rights, in accordance with the terms of the Scheme of Arrangement, to receive, in

exchange for each Scheme Share so transferred, $38.00 in cash, without interest (the “Cash Consideration”), plus one (1) contingent value right per Scheme Share, which shall represent the right to receive the Milestone Payments (as such term is used in the CVR Agreement), if any, at the times and subject to the terms and conditions provided for in the CVR Agreement, in cash, without interest (each, a “CVR” and, collectively, the “CVRs”) (the Cash Consideration plus one (1) CVR, collectively, or any higher amount per Scheme Share paid pursuant to the terms of the Scheme of Arrangement, the “Transaction Consideration”), in each case, subject to the terms and conditions set forth in this Agreement, the CVR Agreement and the Scheme of Arrangement, and less any applicable Tax withholding. For the avoidance of doubt, the Parties acknowledge that, although the holders of Company ADSs are not Scheme Shareholders by virtue of their holdings of Company ADSs, the Depositary Shares are Scheme Shares to be transferred pursuant to the Scheme of Arrangement and accordingly, immediately following the Effective Time and as an indirect consequence of the Scheme of Arrangement, the holders of Company ADSs shall cease to have any rights with respect to the Company ADSs, except for the right to receive in respect of each Company ADS (in the case of certificated Company ADSs, upon surrendering each Company ADS to the Depositary, the Custodian or their respective nominees, as applicable) an amount of cash equal to the Cash Consideration (the “ADS Cash Consideration”), and one (1) CVR (the “ADS CVR” and, together with the ADS Cash Consideration, the “ADS Transaction Consideration”), in each case, subject to the terms and conditions set forth in this Agreement, the CVR Agreement, the Scheme of Arrangement and the Deposit Agreement and less any applicable Tax withholding. As soon as reasonably practicable after the Effective Time, and subject to the payment of all Transfer Taxes in respect of any relevant instruments of transfer (to the extent required), the register of members of the Company will be updated in accordance with this Agreement and the Scheme of Arrangement to reflect the transfer of the Scheme Shares as contemplated hereby and thereby.

(b) Prior to the Closing, Parent shall appoint a commercial bank or trust company reasonably acceptable to the Company (the “Paying Agent”) and enter into a paying agent agreement with the Paying Agent on terms reasonably acceptable to the Company. At or substantially concurrently with the Effective Time, Purchaser or Parent shall procure the deposit with the Paying Agent, for the benefit of the Scheme Shareholders, of cash in an amount sufficient to pay the aggregate amount of the Cash Consideration. All cash deposited with the Paying Agent pursuant to the preceding sentence shall hereinafter be referred to as the “Payment Fund”. Such fund shall not be used for any purpose other than as expressly set forth in this Agreement; provided that such fund may be invested by the Paying Agent as directed by Purchaser or Parent; provided, further, that such investments shall be (i) in obligations of or guaranteed by the United States of America, (ii) in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, (iii) in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $10 billion, or (iv) in money market funds having a rating in the highest investment category granted by a recognized credit rating agency at the time of acquisition or a combination of the foregoing and, in any such case, no such instrument shall have a maturity that is reasonably expected to prevent or delay payments to be made pursuant to this Agreement. Such fund shall not be used for any purpose other than to pay the aggregate amount of Cash Consideration. To the extent that such fund diminishes for any reason below the level required to make prompt payment of the Cash Consideration, Purchaser or Parent shall promptly replace or restore, or cause to be replaced or restored, the lost portion of such fund so as to ensure that it is, at all times, maintained at a level

sufficient to make such payments. No interest shall be paid or shall accrue for the benefit of Scheme Shareholders on the Cash Consideration. Notwithstanding anything to the contrary in this Section 2.1(b), all obligations of Purchaser with respect to the Cash Consideration required to be provided by Purchaser or Parent to the Paying Agent in respect of the Depositary Shares shall be satisfied to the extent Purchaser or Parent provides the Cash Consideration directly to the Depositary, the Custodian or their respective nominees under the Deposit Agreement, as applicable, pursuant to the procedures contemplated by Section 2.1(c). Parent shall not be required to deposit any funds related to any CVR with the Rights Agent, unless and until such deposit is required pursuant to the terms of the CVR Agreement.

(c) Prior to the Closing, the Company and Parent shall establish procedures with the Depositary that are reasonably acceptable to the Company and Parent such that (i) the Depositary, the Custodian or their respective nominees shall promptly deliver the ADS Cash Consideration to each holder of a Company ADS (less applicable Tax withholding) (in the case of certificated Company ADSs, that has duly surrendered such Company ADSs to the Depositary, the Custodian or their respective nominees, as applicable), (ii) any funds unclaimed by holders of Company ADSs shall be treated, as closely as reasonably possible and to the extent permitted by applicable Law, in the same manner as provided under Section 2.1(d), and (iii) if reasonably practicable and to the extent permitted by applicable Law, the aggregate Cash Consideration in respect of the Depositary Shares will be delivered directly by Purchaser or Parent to the Depositary, the Custodian or their respective nominees rather than through the Paying Agent. If reasonably deemed necessary by the Parties in furtherance of the establishment of such procedures, the Company shall enter into one (1) or more amendments to the Deposit Agreement that are reasonably acceptable to the Depositary, the Company and Parent, and the Parties shall deliver any certificates and opinions of counsel reasonably requested by the Depositary in connection therewith. For the avoidance of doubt, Parent shall not be required to deposit any funds related to any CVR with the Rights Agent, unless and until such deposit is required pursuant to the CVR Agreement. Parent will bear all fees, charges and expenses that the Company ADS holders are required to bear under the Deposit Agreement in connection with the Contemplated Transactions, the cancellation of the Company ADSs and the receipt of the ADS Transaction Consideration. No interest will be paid or accrued on any amount payable in respect of the Company ADSs.

(d) Any portion of the Payment Fund which has not been transferred to the holders of Scheme Shares within twelve (12) months of the Closing Date shall be delivered to Purchaser or its designee(s) promptly upon demand by Purchaser and held by Purchaser in accordance with the terms of the Scheme of Arrangement (it being understood that no such delivery shall affect any legal right that a Scheme Shareholder may have to receive the Cash Consideration), and thereafter such Scheme Shareholders shall be entitled to look only to Purchaser for, and Purchaser shall remain liable for, payment of their claims for the Cash Consideration pursuant to the provisions of this Article II and the Scheme of Arrangement.

(e) To the fullest extent permitted by applicable Law, none of Parent, Purchaser, any DR Nominee, the Company, the Paying Agent, the Depositary (or the Custodian or their respective nominees) or any other Person acting as agent for, or otherwise at the direction of, any of the foregoing Persons, including any of their respective Affiliates, directors, officers or employees, will be liable to the Company, the Scheme Shareholders or any other Person in respect of the Cash Consideration (or the ADS Cash Consideration) from the Payment Fund, any CVR or

any other cash or property delivered to a public official pursuant to any applicable abandoned property, escheat or similar applicable Laws. Any amounts remaining unclaimed by such Scheme Shareholders at such time at which such amounts would otherwise escheat to or become property of any Governmental Body shall become, to the extent permitted by applicable Laws, the property of Purchaser or its designee, free and clear of all claims or interest of any Person previously entitled thereto.

(f) If, between the date of this Agreement and the Effective Time, the outstanding Company Shares shall have been changed to, or exchanged for, a different number or class of shares or securities by reason of any stock dividend, bonus issue, scrip dividend, subdivision, reorganization, merger, consolidation, reclassification, redesignation, recapitalization, share split, reverse share split, combination or exchange of shares, or a stock or scrip dividend shall be declared with a record date within such period or any similar event shall have occurred (or if the number of Company Shares represented by each Company ADS shall have been changed pursuant to the Deposit Agreement), then the amount of the Transaction Consideration (or the ADS Transaction Consideration) shall be appropriately adjusted to provide to Purchaser and the Scheme Shareholders (or the Company ADS holders) the same economic effect as contemplated by this Agreement prior to such event; provided that nothing in this Section 2.1(f) shall be construed to permit the Company to take any action with respect to its securities that is prohibited by Section 6.1 or the other terms of this Agreement.

Section 2.2. Treatment of Company Equity Awards.

(a) The Company Board or, if appropriate, the committee administering a Company equity incentive plan, inducement award program or other similar plan, program or arrangement under which equity incentive awards are outstanding, including the Centessa Pharmaceuticals plc Amended and Restated 2021 Share Option and Incentive Plan and any inducement awards, each, as may be amended and restated from time to time (each, a “Company Equity Plan” and, collectively, the “Company Equity Plans”), but excluding the Centessa Pharmaceuticals plc 2021 Employee Share Purchase Plan (the “Company ESPP”), has adopted, or, as soon as practicable following the date of this Agreement (and, in any event, prior to the Effective Time), shall adopt, resolutions providing that, and has taken or shall take other necessary action providing that:

(i) at the Effective Time, each option to purchase Company Shares granted under the Company Equity Plans or otherwise (excluding, for the avoidance of doubt, the Company ESPP) (each, a “Company Stock Option”) having an exercise price less than the Closing Amount (each such option, a “Company Cash-Out Stock Option”) that is outstanding immediately prior to the Effective Time, whether or not vested, will be canceled, and, in exchange therefor, the holder of such canceled Company Cash-Out Stock Option will be entitled to receive (without interest), in consideration of the cancellation of such Company Cash-Out Stock Option, (A) an amount in cash (less applicable Tax withholdings pursuant to Section 2.4) equal to the product of (1) the total number of Company Shares subject to such Company Cash-Out Stock Option immediately prior to the Effective Time multiplied by (2) the excess, if any, of the Closing Amount over the applicable exercise price per Company Share under such Company Cash-Out Stock Option and (B) one (1) CVR for each Company Share subject to such Company Cash-Out Stock Option immediately prior to the Effective Time (without regard to vesting);

(ii) each Company Stock Option having an exercise price that is equal to or greater than the Closing Amount (each such option, a “Company Underwater Option”) that is outstanding immediately prior to the Effective Time, to the extent not vested, will become fully vested as of prior to the Effective Time, and the Company shall permit the holders of Company Underwater Options to exercise such Company Underwater Options prior to the Effective Time on a basis that allows the Company Shares acquired pursuant to such exercise to be treated as Scheme Shares at the Effective Time for purposes of Section 2.1, with any Company Underwater Options that remain outstanding and unexercised as of the Effective Time cancelled for no consideration at the Effective Time, without any action on the part of Purchaser, the Company or any other Person;

(iii) at the Effective Time, each restricted stock unit granted under the Company Equity Plans or otherwise (each such restricted stock unit, a “Company RSU”) that is outstanding and unvested shall become immediately vested in full, and at the Effective Time, each Company RSU will be canceled, and, in exchange therefor, the holder of such canceled Company RSU will be entitled to receive (without interest), in consideration of the cancellation of such Company RSU, (A) an amount in cash (less applicable Tax withholdings pursuant to Section 2.4) equal to the product of (1) the total number of Company Shares subject to such Company RSU immediately prior to the Effective Time, multiplied by (2) the Closing Amount and (B) one (1) CVR for each Company Share subject to such Company RSU immediately prior to the Effective Time (without regard to vesting); and

(iv) each Company Equity Plan shall be terminated effective as of the Effective Time.

(b) Subject to Section 2.4, Parent shall cause the Company (or the relevant Subsidiary, as applicable) to make all payments to former holders of Company Equity Awards required under Section 2.2(a) as promptly as practicable after the Effective Time or a Milestone Payment Date in accordance with the CVR Agreement, as applicable, and, (i) with respect to the Closing Amount, no later than the next regularly scheduled payroll date for U.S. employees that is at least five (5) Business Days following the Effective Time and (ii) with respect to cash payable upon satisfaction of the applicable Milestone (as defined in the CVR Agreement) pursuant to the CVR Agreement, in accordance with Section 2.4(b) of the CVR Agreement.

(c) The Company Board (or, if appropriate, the committee administering the Company ESPP) has passed, or, as soon as practicable after the date hereof shall pass such resolutions and shall take all actions with respect to the Company ESPP that are necessary to provide that: (i) no new ESPP Offering Period shall be authorized or commenced following the date hereof unless and until this Agreement is terminated; (ii) no further rights are granted under the Company ESPP after the Effective Time; and (iii) the Company ESPP shall terminate as of or prior to the Effective Time.

Section 2.3. Section 16 Matters. Prior to the Effective Time, the Company Board shall take all necessary and appropriate action to approve, for purposes of Section 16(b) of the Exchange Act and the related rules and regulations thereunder, the disposition by Company directors and officers of Company Shares (or Company ADSs) and Company Equity Awards in the Contemplated Transactions.

Section 2.4. Withholding. The Parties, the Paying Agent, the Depositary and any other withholding agent are entitled to deduct and withhold from any amounts payable or otherwise deliverable pursuant to this Agreement, the Scheme of Arrangement or the CVR Agreement (including the Transaction Consideration) such amounts as are required to be deducted and withheld therefrom under the United States Internal Revenue Code of 1986, as amended (the “Code”), or the Treasury Regulations thereunder (the “Treasury Regulations”), or any other applicable Law relating to Tax. Any compensatory amounts payable pursuant to or as contemplated by this Agreement, including pursuant to Section 2.2, will be remitted to the applicable payor for payment to the applicable Person through regular payroll procedures, as applicable. To the extent that any amounts are so deducted and withheld and paid over to the appropriate Tax Authority (as applicable), such amounts will be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

Section 2.5. Company and Parent Actions Prior to and at the Closing.

(a) On or prior to the Closing, the Company shall procure that a meeting of the Company Board is held at which resolutions are passed, conditional upon the delivery of the Court Order to the Registrar of Companies in England and Wales (and effective as of the Effective Time), approving the resignation of such directors of the Company (and, if required by Parent, the Company secretary) as Parent shall determine from (i) the Company Board (or as Company secretary) and (ii) the boards of directors of any of the Company’s Subsidiaries on which any such director also sits; provided that Parent provides written notice to the Company identifying the Persons who are to resign not less than ten (10) Business Days prior to Closing.

(b) On the Closing Date, the Company shall deliver to Parent a letter of resignation (in customary form) from each director or Company secretary who is to resign in accordance with Section 2.5(a) (provided that the delivery thereof shall not be a condition to the Closing).

(c) Further Assurances. Subject to the terms and conditions of this Agreement and the Scheme of Arrangement, at any time before or after the Effective Time, Purchaser, Parent and the Company shall each execute any further instruments, deeds, documents, conveyances, assignments or assurances and do all other things reasonably necessary or desirable to consummate the Contemplated Transactions and to carry out the intent and purposes of this Agreement.

ARTICLE III

(a) The Company shall:

(i) as promptly as practicable following the date hereof (with the Company using its reasonable best efforts to do so within twenty (20) Business Days after the date hereof, except to the extent the Company is unable to do so due to Purchaser’s or Parent’s failure to comply with its obligations under Section 3.2), prepare and file with the SEC a proxy statement

in preliminary form relating to the Company Shareholder Meetings, which shall, among other customary items, contain and set out the terms and conditions of the Scheme of Arrangement, the explanatory statement required by section 897 of the Companies Act and the notices convening the Scheme Meeting and the Company GM (such proxy statement, including any amendment or supplement thereto, the “Proxy Statement” and such matters within the Proxy Statement that relate to the Scheme of Arrangement, the “Scheme Document Annex”);

(ii) as promptly as reasonably practicable following the date hereof (and in any event prior to the Court hearing at which an order will be sought in relation to the convening of the Scheme Meeting, except to the extent the Company is unable to do so due to Purchaser’s or Parent’s failure to comply with its obligations under Section 3.2), prepare a draft of any other documentation which is to be filed, published or mailed in connection with the Scheme Document Annex (including the forms of proxy for use by the Company Shareholders at the Company GM and by the Scheme Shareholders at the Scheme Meeting (the “Forms of Proxy”)) (the “Ancillary Scheme Documentation”);

(iii) if it determines that it is required pursuant to applicable Law to file any document other than the Proxy Statement with the SEC in connection with the Contemplated Transactions (such document, an “Other Required SEC Filing”), promptly prepare and file such Other Required SEC Filing;

(iv) use its reasonable best efforts to (A) cause the Proxy Statement (including the Scheme Document Annex), the Ancillary Scheme Documentation and any Other Required SEC Filing (and, in each case, any amendment or supplement thereto) (together, the “Transaction Documentation”) to comply in all material respects with applicable Law (including the Companies Act and any applicable rules and regulations of the SEC and Nasdaq), (B) have the Proxy Statement (including the Scheme Document Annex) clear any SEC review and (C) file with the SEC and cause the Proxy Statement (including the Scheme Document Annex) in definitive form and Forms of Proxy (together with any other Ancillary Scheme Documentation to be mailed) to be mailed to the Company Shareholders as promptly as reasonably practicable after the later of the SEC Proxy Clearance and approval by the Court for convening of the Scheme Meeting;

(v) prior to filing, publishing or mailing any Transaction Documentation or responding to any requests or comments from or by the SEC or (to the extent practicable) the Court with respect to any Transaction Documentation, consult with Parent as to the form and content of such Transaction Documentation, and, for such purpose, shall afford Parent reasonably sufficient time to consider the Transaction Documentation and shall take into account all comments reasonably proposed by Parent or Purchaser, except that no such consultation or consideration shall be required with respect to any disclosure regarding a Change of Board Recommendation made in accordance with Section 6.3;

(vi) inform Parent promptly after it receives any oral or written comment from or request by the SEC, Nasdaq or the Court for amendment of any of the Transaction Documentation or Court Documentation or comments thereon and responses thereto or requests by the SEC, Nasdaq or the Court for additional information, and promptly provide Parent with copies of any written communication from the SEC, Nasdaq or the Court or any state securities commission and use reasonable best efforts to respond as promptly as reasonably practicable to any comments, responses or requests by the SEC, Nasdaq or the Court with respect to the Transaction Documentation and Court Documentation;

(vii) provide Parent with drafts of any documents, witness statements, affidavits or evidence to be submitted to the Court in relation to the Scheme of Arrangement (the “Court Documentation”);

(viii) afford Parent reasonably sufficient time to consider all Court Documentation and take into consideration all comments reasonably proposed by Parent, except that no such consultation or consideration shall be required with respect to any disclosure regarding a Change of Board Recommendation made in accordance with Section 6.3;

(ix) for the purpose of implementing the Scheme of Arrangement, instruct Andrew Thornton KC, a King’s Counsel from Erskine Chambers;

(x) as promptly as reasonably practicable, provide Purchaser and its Representatives with a summary of any advice given by such counsel that is material to the Scheme of Arrangement (including its terms, class analysis, structure and implementation) and, subject to prior agreement from counsel, provide Purchaser’s Representatives with reasonable access to counsel and attendance at any key discussions or conferences with counsel as may be considered appropriate by counsel and the Company;

Section 4.1. Organization and Corporate Power; Subsidiaries.

(a) The Company is duly incorporated and validly existing under the Laws of England and Wales. The Company has all requisite corporate power and authority to own, lease and operate its properties and to carry on its business as it is now being conducted in all material respects. The Company is duly qualified or authorized to do business and is in good standing in every jurisdiction (to the extent such concept exists in such jurisdiction) in which its ownership of property or the conduct of business as now conducted requires it to qualify, except where the failure to be so qualified, authorized or in good standing would not have a Company Material Adverse Effect.

(b) Each Subsidiary of the Company is duly organized, validly existing and in good standing under the Laws of the jurisdiction of its incorporation or organization, as applicable, and has all requisite corporate or other entity power and authority to own, lease and operate its properties and to carry on its business as it is now being conducted in all material respects. The Subsidiaries of the Company are duly qualified or authorized to do business and are in good standing in every jurisdiction (to the extent such concept exists in such jurisdiction) in which its ownership of property or the conduct of business as now conducted requires it to qualify, except where the failure to be so qualified, authorized or in good standing would not have a Company Material Adverse Effect.

(c) True and complete copies of the articles of association of the Company (the “Company Organizational Documents”), and the equivalent governing documents of each of its Subsidiaries, as in effect as of the date of this Agreement, have been heretofore made available to Parent and Purchaser.

(b) The Company Board, at a meeting duly called and at which a quorum was present, duly resolved (i) that this Agreement, the Scheme of Arrangement, the Contemplated Transactions, the Voting and Support Agreements and the other transactions contemplated hereby and thereby are in the best interests of the Company and would promote the success of the Company for the benefit of the Company’s Shareholders as a whole, (ii) that the execution, delivery and performance by the Company of its covenants and obligations contained in this Agreement and the Scheme of Arrangement and the consummation of the Contemplated Transactions upon the terms and subject to the conditions set forth herein and therein, be and are approved, and (iii) to recommend to the Company Shareholders the approval of the Scheme of Arrangement at the Scheme Meeting and the passing of the Company Shareholder Resolution at the Company GM (the matters described in clauses (i) through (iii), the “Company Board Recommendation”), which resolutions have not, as of the date of this Agreement, been rescinded, modified or withdrawn. Except for obtaining the Company Shareholder Approvals and the filing of the Court Order with the Registrar of Companies of England and Wales, no additional corporate proceedings or actions on the part of the Company are necessary to authorize the execution and delivery by the Company of this Agreement, the implementation of the Scheme of Arrangement, the performance by the Company of its covenants and obligations hereunder and thereunder or the consummation of the Contemplated Transactions. The Company has duly executed and delivered this Agreement and the Voting and Support Agreements and, assuming the due authorization, execution and delivery by Purchaser and Parent and such other Persons party to the Voting and Support Agreements, this Agreement and the Voting and Support Agreements constitute its legal, valid and binding obligation, enforceable against it in accordance with its terms except as enforcement may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally and by general principles of equity.

(c) The Company Shareholder Approvals are the only votes of the Company’s Shareholders or the holders of any Company Securities necessary in connection with this Agreement and the Scheme of Arrangement and the consummation by the Company of the Contemplated Transactions.

Section 4.14(a) of the Company Disclosure Letter also sets forth, as of the date of this Agreement, a list of all Internet domain names with respect to which the Company or any of its Subsidiaries is the registrant.

(b) Except for U.S. provisional patent applications and PCT patent applications that have expired or as indicated on Section 4.14(a) of the Company Disclosure Letter, all Company Registered Intellectual Property that is owned or purported to be owned by the Company or its Subsidiaries is subsisting and, to the Knowledge of the Company, in full force and effect and, to the Knowledge of the Company, all Company Registered Intellectual Property that is Exclusive Intellectual Property is subsisting and in full force and effect. The Company and its Subsidiaries (with respect to the Company Registered Intellectual Property that is owned or purported to be owned by the Company or its Subsidiaries) and, to the Knowledge of the Company, the third parties that own the Company Registered Intellectual Property that is Exclusive Intellectual Property (with respect to the Company Registered Intellectual Property that is Exclusive Intellectual Property) (i) have made all necessary filings and paid all necessary registration, maintenance, renewal and other fees required for maintaining the Company Registered Intellectual Property and (ii) have timely filed all necessary documents and certificates in connection therewith with the relevant Patent, Trademark, Copyright, domain name or other authorities in the United States or foreign jurisdictions, as the case may be, for the purpose of maintaining such Company Registered Intellectual Property in full force and effect. The Company or one of its Subsidiaries is the exclusive owner of all rights, title and interests in and to all Owned Intellectual Property, free and clear of all Liens (except for Permitted Liens, non-exclusive licenses granted under the IP Contracts or under Routine Services Contracts entered into in the ordinary course of business, and Liens set forth in Section 4.14(b) of the Company Disclosure Letter), and possesses legally sufficient and enforceable rights pursuant to written agreements to use all other Company Intellectual Property as such Intellectual Property is used in the conduct of the Company’s business; provided, however, that the foregoing will not be interpreted as a representation of non-infringement of third-party Intellectual Property, which is dealt with exclusively in Section 4.14(d) below. Except as set forth in Section 4.14(f) of the Company Disclosure Letter, no third party has any joint ownership in any inventions claimed by any issued Patents or pending claims in any applications for Patents included in the Owned Intellectual Property (or to the Knowledge of the Company, any licensed Company Registered Intellectual Property).

Except as has not had a Company Material Adverse Effect, no public disclosure bar by the Company or its Subsidiaries has occurred or on sale bar by the Company or its Subsidiaries has arisen which has rendered or would reasonably be expected to render any Patent contained in the Owned Intellectual Property (or otherwise in the Company Registered Intellectual Property to the extent the Company controls filing or prosecution thereof) unenforceable or invalid.

Section 6.2. Access to Information; Confidentiality.

(a) From and after the date of this Agreement until the earlier of the Effective Time and the termination of this Agreement in accordance with its terms, the Company shall, and shall cause its Subsidiaries to, (i) upon reasonable advance notice, (A) give Parent and Purchaser and their respective Representatives reasonable access during normal business hours to relevant employees and facilities and to relevant books, contracts and records of the Company and its Subsidiaries, (B) permit Parent and Purchaser to make such non-invasive inspections as they may reasonably request and (C) cause its officers to furnish Parent and Purchaser with such financial and operating data and other information with respect to the business, properties and personnel of the Company and its Subsidiaries as Parent or Purchaser may from time to time reasonably request, in each case of clauses (A) - (C), solely for the purpose of effectuating the Contemplated Transactions and any planning for post-Closing integration, and (ii) reasonably promptly notify Parent of any Healthcare Correspondence.

(b) Subject to Section 9.7, Parent, Purchaser and the Company hereby acknowledge and agree that the confidentiality agreement set forth on Section 6.2(b) of the Company Disclosure Letter (the “Confidentiality Agreement”) will continue in full force and effect in accordance with its terms; provided that, notwithstanding anything to the contrary in the Confidentiality Agreement, the term of the Confidentiality Agreement will automatically be extended, if necessary, through to the earlier of (i) the date of termination of this Agreement and (ii) the Effective Time.

(c) Nothing in Section 6.2(a) requires the Company to permit any inspection, or to disclose any information, that in the reasonable judgment of the Company would (i) violate any of its or its Affiliates’ respective obligations with respect to confidentiality, (ii) result in a violation of applicable Law or (iii) result in loss of legal protection, including the attorney-client privilege and work product doctrine; provided that the Company will use its reasonable best efforts to obtain any required consents for the disclosure of such information and take such other reasonable action (including entering into a joint defense agreement or similar arrangement to avoid loss of attorney-client privilege) with respect to such information as is necessary to permit disclosure to Parent without (x) jeopardizing such attorney-client privilege or work product doctrine or (y) violating applicable Law or any of the Company’s or its Affiliates’ respective obligations with respect to confidentiality, as applicable.

Section 6.3. Acquisition Proposals.

(a) The Company shall not, and shall cause its directors and officers not to, and shall instruct its Representatives not to: (i) directly or indirectly initiate, solicit, or knowingly encourage or knowingly facilitate (including by way of providing information) any inquiries, proposals or offers, or the making of any submission or announcement of any inquiry, proposal or offer that constitutes or would reasonably be expected to lead to any Acquisition Proposal, (ii) directly or indirectly engage in, enter into or participate in any discussions or negotiations with any Person with respect to any Acquisition Proposal or (iii) provide any non-public information to, or afford access to the business, properties, assets, books or records of the Company and its Subsidiaries to, any Person (other than Parent, Purchaser, or any designees of Parent or Purchaser) in connection with any Acquisition Proposal. The Company shall and shall cause its directors and officers to, and shall instruct its Representatives to, (x) immediately cease any solicitation, discussions, or negotiations with any Person (other than Parent, Purchaser, or any designees of

Parent or Purchaser) with respect to any Acquisition Proposal, (y) as soon as reasonably practicable (and in any event within three (3) Business Days after the date of this Agreement) request in writing the prompt return or destruction of all confidential information provided by or on behalf of the Company or its Subsidiaries to any such Person and (z) as soon as reasonably practicable (and in any event within three (3) Business Days after the date of this Agreement) terminate access to any physical or electronic data rooms relating to a possible Acquisition Proposal. Notwithstanding the foregoing, the Company and its Representatives may, solely in response to an inquiry or proposal that did not result from a material breach of this Section 6.3(a), (A) seek to clarify and understand the terms and conditions of any inquiry or proposal made by any Person solely if and to the extent necessary to determine whether such inquiry or proposal constitutes or would reasonably be expected to lead to an Acquisition Proposal and (B) inform a Person that has made or, to the Knowledge of the Company, is considering making an Acquisition Proposal of the provisions of this Section 6.3.

(b) Notwithstanding Section 6.3(a) or any other provision of this Agreement, if at any time following the date of this Agreement and prior to the receipt of the Company Shareholder Approvals, (i) the Company has received a written Acquisition Proposal that did not, directly or indirectly, result from a material breach of Section 6.3(a) and (ii) the Company Board or a committee thereof determines in good faith, after consultation with outside counsel and a financial advisor, that such Acquisition Proposal constitutes or is reasonably likely to lead to or result in a Superior Proposal, then the Company may (A) furnish information with respect to the Company to the Person making such Acquisition Proposal and its Representatives and (B) participate in discussions or negotiations with such Person and its Representatives regarding such Acquisition Proposal; provided that the Company may only take the actions described in clauses (A) or (B) above if the Company Board determines in good faith, after consultation with outside counsel, that the failure to take any such action would be, or would reasonably be expected to be, inconsistent with its fiduciary duties under applicable Law; provided, further, that (1) the Company shall not, and shall instruct its Representatives not to, disclose any material non-public information to such Person unless the Company has, or first enters into, a confidentiality agreement with such Person with terms governing confidentiality that, taken as a whole, are not materially less restrictive or materially more favorable to the other Person than those contained in the Confidentiality Agreement, and does not prohibit the Company from providing any information to Parent in accordance with this Section 6.3 or otherwise prohibit the Company from complying with its obligations under this Section 6.3, and (2) the Company shall, concurrently therewith or as promptly as reasonably practicable thereafter, and in any event within one (1) Business Day, provide or make available to Parent any material non-public information concerning the Company provided or made available to such other Person that was not previously provided or made available to Parent and Purchaser. The Company shall not, directly or indirectly, release any Person from, or waive, amend or modify any provision of, or grant permission under or fail to enforce, any standstill provision in any agreement to which the Company is a party; provided that if the Company Board determines in good faith, after consultation with its outside counsel, that the failure to take such action would be, or would reasonably be expected to be, inconsistent with its fiduciary duties under applicable Law, the Company may waive any such standstill provision solely to the extent necessary to permit the applicable Person (if such Person has not been solicited in breach of this Section 6.3) to make, on a confidential basis to the Company Board, an Acquisition Proposal, conditioned upon such Person agreeing that the Company shall not be prohibited from providing any information to Parent (including regarding any such Acquisition Proposal) in accordance with, and otherwise complying with, this Section 6.3.

(c) The Company shall promptly (and in any event within one (1) Business Day) notify Parent in writing (email being acceptable) of the receipt by the Company of any Acquisition Proposal, inquiry, request for information or other indication by any Person that would reasonably be expected to lead to an Acquisition Proposal. The Company shall (i) provide Parent promptly (and in any event within such one (1) Business Day period) the material terms and conditions of any such inquiry or Acquisition Proposal (including any subsequent material amendments, modifications or supplements thereto), together with copies of all material written proposals or offers related thereto, and the identity of the Person making any such inquiry or Acquisition Proposal and (ii) keep Parent reasonably informed of any material developments regarding any Acquisition Proposal (including any material changes to the terms thereof).

(d) The Company Board and each committee thereof shall not, subject to the terms and conditions of this Agreement, (i) approve or recommend, or propose publicly to approve or recommend, or authorize, cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, license agreement, merger agreement, joint venture agreement, partnership agreement, collaboration agreement, revenue sharing agreement or similar definitive agreement (other than a confidentiality agreement referred to and entered into in compliance with Section 6.3(b)) relating to, or that would reasonably be expected to lead to, any Acquisition Proposal (an “Alternative Acquisition Agreement”) or (ii) make a Change of Board Recommendation.

(e) Notwithstanding Section 6.3(d) or any other provision of this Agreement, prior to the receipt of the Company Shareholder Approvals:

(i) the Company may terminate this Agreement to enter into an Alternative Acquisition Agreement if (A) the Company receives an Acquisition Proposal that did not, directly or indirectly, result from a material breach of Section 6.3(a) and that the Company Board or a committee thereof determines in good faith, after consultation with outside counsel, constitutes a Superior Proposal, (B) the Company has notified Parent in writing that it intends to terminate this Agreement to enter into an Alternative Acquisition Agreement and (C) no earlier than the end of the Notice Period, the Company Board or any committee thereof determines in good faith that the Acquisition Proposal that is subject of the Determination Notice continues to constitute a Superior Proposal and that the failure to terminate this Agreement would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law, after consultation with outside counsel and taking into consideration the terms of any proposed amendment or modification to this Agreement that Parent has irrevocably committed to make during the Notice Period;

(ii) the Company Board or a committee thereof may make a Change of Board Recommendation if (A) the Company receives an Acquisition Proposal that did not, directly or indirectly, result from a material breach of Section 6.3(a), and the Company Board or a committee thereof determines in good faith, after consultation with outside counsel, that the Acquisition Proposal constitutes a Superior Proposal, (B) the Company has notified Parent in writing that it intends to effect a Change of Board Recommendation and (C) no earlier than the

end of the Notice Period, the Company Board or a committee thereof determines in good faith that the failure to make a Change of Board Recommendation would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law and that the Acquisition Proposal that is subject of the Determination Notice continues to constitute a Superior Proposal, after consultation with outside counsel and taking into consideration the terms of any proposed amendment or modification to this Agreement that Parent has irrevocably committed to make during the Notice Period; and

(iii) other than in connection with an Acquisition Proposal, the Company Board or a committee thereof may make a Change of Board Recommendation in response to an Intervening Event if (A) the Company has notified Parent in writing that it intends to effect a Change of Board Recommendation and (B) no earlier than the end of the Notice Period, the Company Board or any committee thereof determines in good faith, after consultation with outside counsel and considering the terms of any proposed amendment or modification to this Agreement that Parent has irrevocably committed to make during the Notice Period, that the failure to effect a Change of Board Recommendation in response to such Intervening Event would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law.

(iv) The provisions of this Section 6.3(e) apply to any amendment to the financial or other material terms of any applicable Superior Proposal with respect to Section 6.3(e)(i) and Section 6.3(e)(ii) and require a revised Determination Notice and a new Notice Period pursuant to clause (i)(C) or (ii)(C) as the case may be. During the Notice Period, if requested by Parent, the Company shall negotiate in good faith with Parent regarding potential changes to this Agreement in such a manner that would eliminate the need for taking the actions set forth in Section 6.3(e)(i), Section 6.3(e)(ii) and Section 6.3(e)(iii) (and in respect of a Superior Proposal, would cause such Superior Proposal to no longer constitute a Superior Proposal).

(f) Nothing contained in this Agreement prohibits (i) the Company Board or a committee thereof from (A) taking and disclosing to the holders of Company Shares a position contemplated by Rule 14e-2 or Rule 14d-9 promulgated under the Exchange Act or (B) making any public statement if the Company Board or a committee thereof determines in good faith, after consultation with outside counsel, that the failure to make such statement would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law or (ii) the Company or the Company Board from making any disclosure required under the Exchange Act; provided that any such action that would otherwise constitute a Change of Board Recommendation shall be made only in compliance with Section 6.3(d) and Section 6.3(e) (it being understood that: (x) any “stop, look and listen” letter or similar communication limited to the information described in Rule 14d-9(f) under the Exchange Act and (y) any disclosure of information to the holders of Company Shares that only describes the Company’s receipt of an Acquisition Proposal and the operation of this Agreement with respect thereto and contains a statement that the Company Board has not effected a Change of Board Recommendation, in each case, shall be deemed not to be a Change of Board Recommendation).

(g) The Company acknowledges and agrees that, for purposes of determining whether a breach of this Section 6.3 has occurred, the actions of the Company’s directors and Representatives acting solely in their authorized capacities on behalf of the Company shall be deemed to be the actions of the Company, and the Company shall be responsible for any breach of this Section 6.3 by its directors and Representatives acting solely in their authorized capacities on behalf of the Company.

Section 6.4. Employment and Employee Benefits Matters.

(a) For twelve (12) months following the Closing Date (or, if earlier, until the termination date of a Current Employee, as defined below), Parent shall, or shall cause the Company to, provide each individual employed by the Company or its Subsidiaries at the Effective Time (each, a “Current Employee”), to the extent they continue to be employed by Parent or the Company (i) total base compensation or base hourly wage (as applicable) and target annual cash incentive compensation opportunity (excluding, for the avoidance of doubt, any long-term incentive or equity or equity-based opportunities) at least as favorable, in the aggregate, for each such Current Employee, as the total base compensation or base hourly wage rate (as applicable) and target cash annual incentive opportunity provided to the Current Employee as of immediately prior to the Effective Time (subject to the same exclusions), and (ii) employee benefits that are substantially comparable in the aggregate to those benefits maintained for and provided to the Current Employees under the Company Plans that are disclosed in Section 4.17(a) of the Company Disclosure Letter (excluding cash incentive opportunities, severance, equity and equity-based awards, long-term incentive, retention, change in control-related payments or benefits, nonqualified deferred compensation, defined benefit plan and post-employment or retiree welfare benefits, collectively, the “Excluded Benefits”) and in effect as of immediately prior to the Effective Time or, to the extent a Current Employee becomes covered by an employee benefit plan or program of Parent (or one of its Affiliates other than the Company) during such period, employee benefits at least as favorable (other than the Excluded Benefits) as those maintained for and provided to similarly situated employees of Parent (or its relevant Affiliate).

(b) For a period of one year following the Effective Time, Parent shall provide, or cause to be provided, to each Current Employee who suffers a termination of employment under circumstances that would have given the Current Employee a right to severance payments and benefits under any Company Plan set forth on Section 6.4(b) of the Company Disclosure Letter and in effect immediately prior to the Closing Date with severance payments and benefits no less favorable than those that would have been provided to such Current Employee under such applicable Company Plan.

(c) Parent shall, and shall cause the Company to, cause service rendered by each Current Employee to the Company or its Subsidiaries prior to the Effective Time to be taken into account with respect to only the employee benefit plans of Parent and the Company which provide benefits for vacation, paid time-off or 401(k) savings (and for the avoidance of doubt, not for any purpose under any Excluded Benefit), for purposes of determining eligibility to participate, level of benefits and vesting, in each case to the same extent and for the same purpose as such service was taken into account under the corresponding Company Plans immediately prior to the Effective Time for those purposes; provided that the foregoing will not apply to (i) the extent that its application would result in a duplication of benefits or compensation with respect to the same period of service, (ii) any benefit plan that is a frozen plan or that provides benefits to a grandfathered employee population or (iii) to the extent such service would not be credited to similarly situated employees of Parent or its Affiliates. Without limiting the generality of the foregoing, for the plan year in which the Effective Time occurs, Parent shall, or shall cause the

Company to, use commercially reasonable efforts to waive for the Current Employees any eligibility requirements, waiting periods, actively-at-work requirements or pre-existing condition limitations under any health plan of Parent or the Company for any condition for which they would have been entitled to coverage under the corresponding Company Plan in which they participated immediately prior to the Effective Time.

(d) If requested by Parent, the Company shall, at least one (1) day prior to the Effective Time, (i) adopt written resolutions (or take other necessary and appropriate actions) to terminate each Company Plan intended to be qualified under Section 401(a) of the Code (the “401(k) Plan”), (ii) cease all contributions to the 401(k) Plan for any compensation paid after such termination date, and (iii) one hundred percent (100%) vest all participants under the 401(k) Plan, with such termination, cessation and vesting to be effective no later than the day preceding the Effective Time.

(e) Prior to making any written or broad-based oral communications to any current or former officer, director, employee, worker or individual independent contractor (whether engaged directly or via a personal service company) of the Company or its Subsidiaries pertaining to compensation or benefit matters described in this Agreement or to compensation or benefits that will be provided by Parent or Purchaser or an Affiliate thereof following the Closing, the Company shall provide Parent with a copy of the intended communication, Parent shall have a reasonable period of time to review and comment on the communication, and the Company shall consider any such comments in good faith (it being understood that after Parent has been so provided with such opportunity, the Company shall not be required to provide Parent with any other communication if the content thereof is substantially the same as that previously reviewed by Parent).

(f) Without limiting the generality of Section 6.4, no provision of this Agreement (i) prohibits Parent, Purchaser or the Company from amending, modifying or terminating any individual Company Plan or any other benefit or compensation plan, program, contract, agreement, policy or arrangement in a manner that does not conflict with or contravene the obligations of Parent, Purchaser, the Company or any of their respective Affiliates under this Section 6.4, (ii) requires Parent, Purchaser or the Company to keep any Person employed or otherwise providing services for any period of time, or (iii) constitutes or shall be construed to constitute the establishment or adoption of, or amendment to, any Company Plan or other benefit or compensation plan, program, contract, agreement, policy or arrangement. This Section 6.4 shall not confer upon any Current Employee or any other Person (including any beneficiary or dependent thereof) not a party to this Agreement any third-party beneficiary or similar rights or remedies.

Section 6.5. Directors’ and Officers’ Indemnification and Insurance.

(a) To the extent permitted by applicable Law, Parent and Purchaser shall cause the Company’s articles of association and the organizational documents of the Company’s Subsidiaries to contain provisions no less favorable with respect to indemnification, advancement of expenses, and exculpation from liabilities of present and former directors, officers, and employees of the Company and its Subsidiaries than are currently provided in the Company Organizational Documents and the organizational documents of the Company’s Subsidiaries,

which provisions may not be amended, repealed, or otherwise modified in any manner that would adversely affect the rights thereunder of any such individuals until six (6) years from the Effective Time, and in the event that any Action is pending or asserted or any claim made during such period, until the disposition of any such Action or claim, unless such amendment, modification, or repeal is required by applicable Law, in which case Parent shall, and shall cause the Company to, make such changes to such organizational documents as to have the least adverse effect on the rights of the individuals referenced in this Section 6.5.

(b) Without limiting any additional rights that any Person may have under any agreement or Company Plan, from and after the Effective Time, Parent shall cause the Company to indemnify and hold harmless each present (as of the Effective Time) or former director or officer of the Company and its Subsidiaries (each, together with such Person’s heirs, executors, administrators, or Affiliates, an “Indemnified Party”), against all obligations to pay a judgment, settlement, or penalty and reasonable expenses incurred in connection with any pending, threatened or actual Action, whether civil, criminal, administrative, arbitrative, or investigative, and whether formal or informal, arising out of the fact that the Indemnified Party is or was an officer, director, employee, Affiliate, fiduciary, or agent of the Company, its Subsidiaries or of another entity if such service was at the request of the Company, whether asserted or claimed prior to, at, or after the Effective Time, to the fullest extent permitted under applicable Law. In the event of any such Action, Parent shall cause the Company to advance to each Indemnified Party reasonable and documented out-of-pocket expenses incurred in the defense of the Action (provided that any Person to whom expenses are advanced shall have provided, an undertaking to repay such advances if it is finally determined that such Person is not entitled to indemnification). The Company shall reasonably cooperate with an Indemnified Party in the defense of any matter for which such Indemnified Party could seek indemnification hereunder. The Company’s obligations under this Section 6.5 shall continue in full force and effect for the period beginning upon the Effective Time and ending six (6) years from the Effective Time; provided that all rights to exculpation, indemnification and advancement in respect of any Action asserted or made within such period shall continue until the final disposition of such Action. Parent shall guarantee the performance by the Company of its obligations under this Section 6.5(b).

(c) Notwithstanding anything to the contrary in this Agreement, at or prior to the Effective Time, following good faith consultation with Parent and, if requested by Parent, utilizing a broker of Parent’s choice which is of similar reputation and standing as the Company’s broker, the Company may purchase a tail policy under the current directors’ and officers’ liability insurance policies maintained at such time by the Company, which tail policy (i) will be effective for a period from the Effective Time through and including the date six (6) years after the Effective Time with respect to claims arising from facts or events that existed or occurred prior to or at the Effective Time and (ii) will contain coverage that is at least as protective to such directors and officers as the coverage provided by such existing policies; provided that the aggregate premium for such tail policy may not be in excess of three hundred percent (300%) of the last annual premium paid prior to the Effective Time (the “Maximum Amount”). Parent shall cause such policy to be maintained in full force and effect for their full term, and cause all obligations thereunder to be honored by the Company; provided that neither Parent nor the Company shall be required to pay an aggregate premium for such insurance policies in excess of the Maximum Amount; provided, further, that if the aggregate premium of such insurance coverage exceeds such amount, the Company shall be obligated to obtain the maximum amount of coverage available for the Maximum Amount.

(d) Without limiting any of the rights or obligations under this Section 6.5, from and after the Effective Time, the Company shall keep in full force and effect, and shall comply with the terms and conditions of, any agreement in effect as of the date of this Agreement between or among the Company and any Indemnified Party providing for the indemnification of such Indemnified Party and Parent hereby guarantees the obligations of the Company pursuant to such agreements, each as set forth on Section 6.5(d) of the Company Disclosure Letter.

(e) This Section 6.5 will survive the consummation of the Contemplated Transactions and is intended to benefit, and is enforceable by, any Person or entity referred to in this Section 6.5. The indemnification and advancement provided for in this Section 6.5 is not exclusive of any other rights to which the Indemnified Party is entitled whether pursuant to Law, Contract, or otherwise. If the Company or any of its successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity resulting from such consolidation or merger or (ii) transfers all or a majority of its properties and assets to any Person, then, and in each such case, Parent shall make proper provisions such that the successors and assigns of the Company assume the applicable obligations set forth in this Section 6.5.

(f) If any Indemnified Party makes any claim for indemnification or advancement of expenses under this Section 6.5 that is denied by Parent and/or the Company, and a court of competent jurisdiction makes a final and non-appealable determination that the Indemnified Party is entitled to such indemnification or advancement of expenses, then Parent or the Company shall pay the Indemnified Party’s costs and expenses, including reasonable legal fees and expenses, incurred by the Indemnified Party in connection with pursuing his or her claims to the fullest extent permitted by law.

(g) Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or its Subsidiaries for any of their respective directors, officers or other employees, it being understood and agreed that the indemnification provided for in this Section 6.5 is not prior to or in substitution for any such claims under such policies.

Section 6.6. Further Action; Efforts.

(a) Subject to the terms and conditions of this Agreement and the Scheme of Arrangement, prior to the Effective Time, each party shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper, or advisable under applicable Laws to consummate the Contemplated Transactions as promptly as practicable and, in any event, by or before the Outside Date. Notwithstanding anything in this Agreement to the contrary, the Parties agree to, or to cause their ultimate parent entity (as such term is defined in the HSR Act) to, (i) make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the Contemplated Transactions as promptly as reasonably practicable and in any event prior to the expiration of any applicable legal deadline

(provided that, unless otherwise agreed by the Company and Parent in writing, the filing of a Notification and Report Form pursuant to the HSR Act must be made within fifteen (15) Business Days from the date hereof) and (ii) to supply as promptly as practicable any additional information and documentary material that may be requested pursuant to the HSR Act or any other Antitrust Law. The parties also shall consult and cooperate with one another, and consider in good faith the reasonable views of one another, in connection with, and provide to the other parties in advance, any analyses, appearances, presentations, memoranda, briefs, arguments, opinions, and proposals made or submitted by or on behalf of such party in connection with proceedings under or relating to any Antitrust Laws. The Parties shall jointly direct, devise and implement the strategy to obtain any necessary approvals from, submit filings to, respond to any request from or inquiry or investigation by (including directing the timing, nature and substance of all such responses), and shall have the right to co-lead all meetings and communications with, any Governmental Body that has the authority to enforce any Antitrust Law; provided that, subject to its undertakings in this Section 6.6, the final determination as to the appropriate course of action shall be made by Parent. Without limiting the foregoing, the Parties agree (A) to give each other reasonable advance notice of all substantive meetings with any Governmental Body relating to any Antitrust Laws, (B) to the extent reasonably practicable, to give each other an opportunity to participate in each of such meetings, (C) to the extent reasonably practicable, to give each other reasonable advance notice of all substantive oral communications with any Governmental Body relating to any Antitrust Laws, (D) if any Governmental Body initiates a substantive oral communication regarding any Antitrust Laws, to promptly notify the other party (and its outside legal counsel) of the substance of such communication, (E) to provide each other with a reasonable advance opportunity to review and comment upon all substantive written communications (including any analyses, presentations, memoranda, briefs, arguments, opinions and proposals) with a Governmental Body regarding any Antitrust Laws and (F) to provide each other (and its outside legal counsel) with copies of all written communications to or from any Governmental Body relating to any Antitrust Laws. Any such disclosures or provision of copies by one party to the other may be made on an outside counsel/in-house counsel basis, if appropriate. Each Party may, as each deems advisable and necessary, reasonably designate any such disclosures or provision of copies by one party to the other party under this Agreement as “outside counsel/in-house counsel only.” Such designated materials and the information contained therein shall be given only to the outside legal counsel and in-house counsel of the recipient and shall not be disclosed by such outside counsel and in-house counsel to employees (other than in-house counsel), officers or directors of the recipient, unless express permission is obtained in advance from the source of the materials or its legal counsel; it being understood that materials provided pursuant to this Agreement may be redacted (1) to remove references concerning the valuation of the Company or the Contemplated Transactions, (2) as necessary to comply with contractual obligations and (3) as necessary to protect privileged attorney-client communications or attorney work product.

(b) Each Party shall, and shall cause each of their respective Subsidiaries to, use its reasonable best efforts to obtain any consents, clearances, or approvals required under or in connection with the Antitrust Laws to enable all waiting periods under applicable Antitrust Laws to expire, and to avoid or eliminate impediments under applicable Antitrust Laws asserted by any Governmental Body, in each case, to cause the Contemplated Transactions to occur as promptly as practicable and, in any event, by or before the Outside Date, including (i) as promptly as reasonably practicable complying with any requests for additional information (including any second request) by any Governmental Body and (ii) contesting and defending any threatened or

pending preliminary or permanent injunction or other order or any claim or determination, decree, or ruling or statute, rule, regulation, or executive order that would adversely affect the ability of any Party to consummate the Contemplated Transactions and taking other actions to prevent the entry, enactment, or promulgation thereof, it being understood that, notwithstanding Section 6.6(a) above, Parent shall have the right to direct, devise and control such litigation. Parent shall pay all filing fees incurred by the parties in connection with any filings which may be required by such party to obtain clearance under any Antitrust Law for the consummation of the Contemplated Transactions (other than, for the avoidance of doubt, fees and expenses of counsel or other advisors to the Company). Notwithstanding anything to the contrary in this Section 6.6(b) or otherwise in this Agreement, neither Parent nor any of its Affiliates shall have any obligation to offer, negotiate, commit to, or effect, by consent decree, hold separate order, or otherwise, the sale, divestiture, license, or other disposition of any or all of the capital stock, assets, equity holdings, rights, products, or businesses of Parent or any of its Subsidiaries (including, following the Effective Time, the Company), or any other restrictions on the activities of Parent or any of its Subsidiaries (including, following the Effective Time, the Company). In addition, the Company shall not offer or commit to take any of such actions without Parent’s prior written consent, which includes taking or committing to take actions that limit Parent or any of its Subsidiaries (including, following the Effective Time, the Company), as applicable, freedom of action with respect to, or their ability to retain, any of the businesses, employees, or assets of the Company, and Parent and its Affiliates shall not be required to commit to any provision (in any consent decree or otherwise) requiring the prior approval of a Governmental Body to engage, or agree not to engage in any present or future transaction involving Parent or any of its Affiliates. Parent shall not require the Company to, and the Company shall not be required to, take any action with respect to any consent decree, hold separate order or other applicable Law that binds the Company prior to the Effective Time. Neither Parent nor the Company shall enter any agreement with a Governmental Body not to consummate or to delay consummation of the Contemplated Transactions without the prior written consent of the other party to the extent permissible by Laws; provided that Parent shall be permitted without the Company’s consent (it being understood that Parent may exercise this right only one time) to withdraw their filing under the HSR Act in connection with the Contemplated Transactions and promptly refile the notification and report forms within two (2) Business Days (as required by the HSR Act) with respect to the Contemplated Transactions.

(c) From the date of this Agreement through the date that is ninety (90) days after the date of this Agreement, Parent shall not, and shall cause its Subsidiaries and Affiliates not to, acquire or agree to acquire a majority of the equity interests of, or all or substantially all assets of, any Persons or divisions thereof (through acquisition, license, joint venture, collaboration or otherwise), or the exclusive license of the commercial rights of an asset, if such an acquisition or license (A) involves an orexin-2 or sodium oxybate asset or program in clinical development, and (B) would reasonably be expected to materially delay or prevent the receipt of any authorizations, consents, orders, declarations or approvals of any Governmental Body necessary to close the Contemplated Transactions.

(d) Prior to the Effective Time, each party shall use commercially reasonable efforts to obtain any consents, approvals, or waivers of third parties with respect to any Contracts to which it is a party as may be necessary for the consummation of the Contemplated Transactions or required by the terms of any Contract as a result of the execution, performance, or consummation of the Contemplated Transactions; provided that, in no event will the Company be required to pay, prior to the Effective Time, any fee, penalty, or other consideration or make any other accommodation to any third party to obtain any consent, approval, or waiver required with respect to any such Contract.

Section 6.7. Public Announcements. The Company shall not, and Parent shall not, and shall cause each of its Subsidiaries to not, issue any press release or announcement concerning the Contemplated Transactions without the prior consent of the other (which consent may not be unreasonably withheld, conditioned, or delayed), except any release or announcement required by applicable Law or any rule or regulation of Nasdaq, the New York Stock Exchange or any other stock exchange to which the relevant party is subject, in which case the party required to make the release or announcement shall use commercially reasonable efforts to allow each other party reasonable time to comment on such release or announcement in advance of such issuance; it being understood that the final form and content of any such release or announcement, to the extent so required, shall be at the final discretion of the disclosing party. The Parties agree that the initial press release relating to this Agreement shall be a joint press release issued by the Company and Parent. The restrictions of this Section 6.7 do not apply to communications by the Company in connection with, or following, an Acquisition Proposal, Superior Proposal, Change of Board Recommendation, Intervening Event or any action taken pursuant thereto (or communications made or proposed to be made by Parent in response thereto), in each case, that does not violate Section 6.3.

Section 6.8. Conduct of Parent and Purchaser. Parent shall, immediately following execution of this Agreement, cause the sole stockholder of Purchaser to execute and deliver a written consent of the sole stockholder adopting this Agreement in accordance with applicable Law and the certificate of incorporation and bylaws of Purchaser.

Section 6.9. No Control of the Company’s Business. Nothing contained in this Agreement gives Parent or Purchaser, directly or indirectly, the right to control or direct the Company’s operations prior to the Effective Time. Prior to the Effective Time, the Company shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its operations.

Section 6.10. Operations of Purchaser. Prior to the Effective Time, Purchaser shall not engage in any other business activities and shall not incur any liabilities or obligations other than as contemplated herein.

Section 6.11. Shareholder Litigation. The Company shall promptly notify Parent of any Actions or claims instituted against the Company, its Subsidiaries or any of their directors or officers, in each case, relating to this Agreement or the Contemplated Transactions (each such item described in this Section 6.11, “Shareholder Litigation”). Parent shall have the right to participate in the defense of any such Shareholder Litigation, the Company shall consult with Parent (which advice the Company shall consider in good faith) regarding the defense of any such Shareholder Litigation, and the Company shall not settle or compromise any Shareholder Litigation without the prior written consent of Parent, not to be unreasonably withheld, delayed or conditioned, unless (a) such settlement is fully covered by the Company’s insurance policies (other than any applicable deductible) or (b) such settlement relates solely to the provision of additional disclosure in the Proxy Statement (including the Scheme Document Annex), but in each case only if such settlement

would not result in the imposition of any restriction on the business or operations of the Company or its Affiliates. The Company shall notify Parent promptly of the commencement or written threat of any proceedings of which it has received notice or become aware and shall keep Parent promptly and reasonably informed regarding any such proceedings. Without otherwise limiting the Indemnified Parties’ rights with regard to the right to counsel as described in Section 6.5, following the Effective Time, the Indemnified Parties shall be entitled to continue to retain Goodwin Procter LLP or such other counsel selected by such Indemnified Parties prior to the Effective Time to defend any Shareholder Litigation relating to the Company.

Section 6.12. Regulatory Matters. Between the date of this Agreement and the earlier of the Effective Time or the termination of this Agreement, the Company and its Subsidiaries shall make available to Parent and its Representatives complete and accurate copies of (a) all material clinical and non-clinical data relating to the Products and (b) all material written or oral correspondence between the Company or its Subsidiaries, on the one hand, and the applicable Governmental Bodies, on the other hand, relating to the Company, its Subsidiaries, or the Products, in the case of each of clauses (a) and (b) above, that comes into the Company’s or its Subsidiaries’ possession or control during such time period promptly (and in any event no later than three (3) Business Days) after the Company obtains such possession or control thereof and subject to the limitations set forth in Section 6.2 (it being understood that data and correspondence in the possession of a contract research organization or similar third party acting on behalf of the Company shall not be deemed to be in possession of the Company solely by reason of its being in the possession of such third party). The Company shall, and shall cause its Subsidiaries to, and shall direct its and their Representatives to reasonably consult and cooperate with Parent, as and to the extent reasonably requested by Parent, and consider in good faith the views and comments of Parent in connection with any material communications (including meetings or teleconferences) with any Governmental Body relating to clinical and preclinical trials related to the Products.

Section 6.13. Cash Management. Prior to the Effective Time, the Company shall convert all Investment Securities to Cash and Cash Equivalents.

Section 6.14. Stock Exchange De-listing. The Company shall cause the Company ADSs to be de-listed from Nasdaq and de-registered under the Exchange Act as promptly as practicable following the Effective Time.

Section 6.15. Termination of Certain Agreements. At or prior to the Effective Time, the Company shall terminate, or cause to be terminated, the Contracts set forth on Section 6.15 of the Company Disclosure Letter, with such termination(s) becoming effective no later than as of the Effective Time.

Section 6.16. CVR Agreement. At or prior to the Effective Time, each of Parent and Purchaser shall authorize and duly adopt, execute and deliver, and will ensure that a duly qualified Rights Agent executes and delivers, the CVR Agreement, subject to any reasonable revisions to the CVR Agreement that are requested by such Rights Agent and/or the Depositary (provided that such revisions are not, individually or in the aggregate, detrimental or adverse, taken as a whole, to any holder of a CVR). Parent, Purchaser and the Company shall cooperate, including by making changes to the form of CVR Agreement, as necessary to ensure that the CVRs are not subject to registration under the Securities Act, the Exchange Act or any applicable state securities or “blue sky” laws.

Section 6.17. Tax Matters. The Company and Parent shall (and shall, in the case of the Company, procure that its Subsidiaries and its and their Representatives shall) provide such assistance and information as such other Party may reasonably request in connection with any matters relating to Tax in respect of the Contemplated Transactions and with respect to tax periods of the Company and its Subsidiaries, including in respect of any Tax clearances or consents that any such Party may consider necessary or desirable in connection with the Contemplated Transactions (including in connection with any UK stamp duty or stamp duty reserve tax). The Company shall, as soon as reasonably practicable after the date hereof, apply for confirmation from His Majesty’s Revenue & Customs that the Court Order is not subject to United Kingdom stamp duty or stamp duty reserve tax. For the avoidance of doubt, failure to obtain such confirmation shall not constitute a breach of the Company’s obligations under this Agreement.

Section 6.18. Company Indebtedness. Prior to the Closing, the Company shall, and shall cause its Subsidiaries to, deliver notices of prepayment and notices of termination of commitments (including any certifications or calculations to be provided therewith) relating to the prepayment in full of outstanding indebtedness under the Company Credit Agreement at the Closing. The Company and its Subsidiaries shall use their reasonable best efforts to (a) obtain and deliver to Parent prior to the Closing payoff letters in customary form from the lenders (or their applicable Representatives) with respect to the Company Credit Agreement stating the amounts required to pay in full all indebtedness thereunder at the Closing and (b) obtain and deliver to Parent documents and filings in customary form acknowledging the termination of obligations and release of Liens related to the Company Credit Agreement upon the payoff of the outstanding indebtedness under the Company Credit Agreement. The Company shall use reasonable best efforts to assist Parent (and Parent shall use reasonable best efforts to assist the Company in connection therewith) in the prepayment in full of all indebtedness under the Company Credit Agreement and the termination of the Company Credit Agreement as of the Effective Time and the release of any related Liens, guaranties and other credit support thereunder upon the occurrence of such prepayment (provided that no such prepayment shall be required that is not contingent on the occurrence of the Closing). Without limiting the generality of the foregoing, the Company and its Subsidiaries shall use reasonable best efforts to deliver to Parent at least three (3) Business Days prior to the Closing Date draft payoff letters, termination acknowledgments and release documentation, and the Company shall give due consideration to all reasonable comments thereto requested in writing by Parent or its counsel.

Section 6.19. Switching. Neither Purchaser nor Parent may elect to implement the acquisition of the entire issued share capital of the Company as contemplated by this Agreement by means of a takeover offer within the meaning of section 974 of the Companies Act, or otherwise announce any such takeover offer in respect of the Company, at any time without the Company’s prior written consent (to be granted in the Company’s sole discretion).

Section 6.20. Anti-Takeover Laws. If any state Anti-Takeover Law becomes or is deemed to be applicable to this Agreement or the Contemplated Transactions, then Parent, Purchaser and the Company shall cooperate and take all action reasonably available to render such Law inapplicable to the foregoing; provided, however, that nothing in the foregoing shall be interpreted to require the Company Board (or a committee thereof) to take any action that would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law or following a Change of Board Recommendation pursuant to Section 6.3. The Company shall not take (or omit to take) any action that would reasonably be expected to result in (a) the United Kingdom City Code on Takeovers and Mergers applying to the Company or the Contemplated Transactions or (b) the Contemplated Transactions becoming subject to the jurisdiction of the United Kingdom Panel on Takeovers and Mergers; provided, however, that nothing in the foregoing shall be interpreted to require the Company or the Company Board (or a committee thereof) to refrain from taking any action that would reasonably be expected to be inconsistent with the fiduciary duties of the Company Board under applicable Law or any other action following a Change of Board Recommendation pursuant to Section 6.3.

ARTICLE VIII

TERMINATION, AMENDMENT AND WAIVER

Section 8.1. Termination by Mutual Agreement. This Agreement may be terminated, and the Contemplated Transactions may be abandoned, at any time prior to the Effective Time, by mutual written consent of Parent and the Company.

Section 8.2. Termination by Either Parent or the Company. This Agreement may be terminated, and the Contemplated Transactions may be abandoned, at any time prior to the Effective Time, by Parent or the Company, if:

(a) any Governmental Body has issued a final order, decree or ruling, or taken any other final action permanently restraining, enjoining, or otherwise prohibiting the Contemplated Transactions, and such order, decree, ruling or other action has become final and non-appealable; provided, however, that this termination right is not available to any Party, if the issuance of such order, decree, ruling or other action is primarily attributable to the failure on the part of such Party to comply with its obligations under this Agreement in any material respect, including Section 6.6;

(b) the Closing has not occurred on or prior to 11:59 p.m. Eastern Time, on the date that is six (6) months after the date of this Agreement (the “Outside Date”); provided, however, that if as of such date, all of the conditions set forth in Article VII (other than Section 7.1(c) or Section 7.1(d)) (solely with in respect of Antitrust Laws) shall have been satisfied or waived by Parent or Purchaser, to the extent waivable by Parent or Purchaser (other than conditions that by their nature are to be satisfied on the Closing Date, each of which is then capable of being satisfied), then the Outside Date will automatically be extended by six (6) months until 11:59 p.m. Eastern Time, on the date that is twelve (12) months after the date of this Agreement (and such date will then be the Outside Date); provided, however, that this termination right is not available to any Party, if the failure of the Effective Time to occur prior to the Outside Date is primarily attributable to the failure on the part of such Party to comply in any material respect with its obligations under this Agreement, including Section 6.6;

(c) the Scheme Meeting or the Company GM (including, in each case, any postponements or adjournments thereof) shall have been completed and any Company Shareholder Approval voted on at such meeting shall not have been obtained; or

(d) the Court declines or refuses to sanction the Scheme of Arrangement; provided that if an appeal has been submitted by either Parent or the Company in respect of any such decline or refusal, the right to terminate the Agreement pursuant to this Section 8.2(d) may not be exercised until such appeal has been denied in a final determination.

Section 8.3. Termination by the Company. This Agreement may be terminated at any time prior to the Effective Time, by the Company, if:

(a) there has been a breach of any covenant or agreement made by Parent or Purchaser in this Agreement, or any representation or warranty of Parent or Purchaser is inaccurate or becomes inaccurate after the date of this Agreement, and such breach or inaccuracy would give rise to the failure of a condition set forth in Section 7.3(a) or Section 7.3(b), and such breach or inaccuracy is not capable of being cured within thirty (30) days following receipt by Parent or Purchaser of written notice of such breach or inaccuracy or, if such breach or inaccuracy is capable of being cured within such period it has not been cured within such period; provided that the Company shall not have the right to terminate this Agreement pursuant to this Section 8.3(a) if the Company is then in breach of any of its covenants, agreements, representations, or warranties hereunder such that Parent would be entitled to terminate this Agreement pursuant to Section 8.4(a); or

(b) at any time prior to obtaining the Company Shareholder Approvals, in order to enter into an Alternative Acquisition Agreement with respect to a Superior Proposal in accordance with Section 6.3(e)(i); provided that, promptly following such termination, the Company enters into an Alternative Acquisition Agreement in respect of such Superior Proposal and pays (or causes to be paid) the termination fee due pursuant to Section 8.5(b).

Section 8.4. Termination by Parent. This Agreement may be terminated at any time prior to the Effective Time by Parent, if:

(a) there has been a breach of any covenant or agreement made by the Company in this Agreement, or any representation or warranty of the Company is inaccurate or becomes inaccurate after the date of this Agreement, and such breach or inaccuracy would give rise to the failure of a condition set forth in Section 7.2(a) or Section 7.2(b), and such breach or inaccuracy is not capable of being cured within thirty (30) days following receipt by the Company of written notice of such breach or inaccuracy or, if such breach or inaccuracy is capable of being cured within such period, it has not been cured within such period; provided that Parent shall not have the right to terminate this Agreement pursuant to this Section 8.4(a) if Parent or Purchaser is then in breach of any of its covenants, agreements, representations or warranties hereunder such that the Company would be entitled to terminate this Agreement pursuant to Section 8.3(a); or

(b) at any time prior to obtaining the Company Shareholder Approvals, the Company Board or any committee thereof effects a Change of Board Recommendation.

Section 8.5. Effect of Termination.

(a) In the event of termination of this Agreement pursuant to this Article VIII, this Agreement (other than Section 6.2(b), Article VIII and Article IX, each of which will survive any termination hereof) will become void and of no effect with no liability on the part of any Party (or of any of its Representatives); provided, however, that except in a circumstance where the termination fee is paid by the Company pursuant to Section 8.5(b) below, no such termination will relieve any Party of any liability for damages resulting from material breach of this Agreement that is a consequence of an act or omission intentionally undertaken by the breaching Party with the actual knowledge that such act or omission would result in a material breach of this Agreement (an “Intentional Breach”), including with respect to the making of a representation set forth herein, or would constitute fraud. For purposes of this Section 8.5(a), “fraud” means actual (and not constructive, including claims based on recklessness) common law fraud under Delaware law with respect to the making of an express representation or warranty contained in this Agreement.

(b) In the event that:

(i) this Agreement is terminated by the Company pursuant to Section 8.3(b) (Superior Proposal);

(ii) this Agreement is terminated by Parent pursuant to Section 8.4(b) (Change of Board Recommendation); or

(iii) (A) this Agreement is terminated (x) by either Parent or the Company pursuant to (1) Section 8.2(b) (Outside Date) (in the case of a termination by the Company, only if at such time Parent would not be prohibited from terminating this Agreement pursuant to the second proviso in Section 8.2(b) (Outside Date)), (2) Section 8.2(c) (Company Shareholder Approval) or (3) Section 8.2(d) (Scheme of Arrangement), or (y) by Parent pursuant to Section 8.4(a) (Material Breach), (B) any Person has publicly disclosed an Acquisition Proposal (which has not been irrevocably publicly withdrawn at least one (1) day (1) prior to the Outside Date in the case of Section 8.5(b)(iii)(A)(x)(1), (2) prior to the date of the action or event giving rise to termination in the case of Section 8.5(b)(iii)(A)(x)(2) and Section 8.5(b)(iii)(A)(x)(3) or (3) prior to the date of such material breach in the case of Section 8.5(b)(iii)(A)(y)) after the date of this Agreement and prior to such termination and (C) within twelve (12) months after such termination, the Company enters into an Alternative Acquisition Agreement with respect to an Acquisition Proposal (and the transactions contemplated by such Acquisition Proposal are subsequently consummated before or after the expiration of such twelve (12)-month period) or the Acquisition Proposal is consummated (provided that, for purposes of clause (C) of this Section 8.5(b)(iii), references to “20%” in the definition of Acquisition Proposal will be substituted with “50%”);

Then, in any such case, the Company shall pay (or cause to be paid to) Parent a termination fee of $63,058,601.76, by wire transfer of immediately available funds to the account or accounts designated by Parent. Any payment required to be made (1) pursuant to clause (i) of this Section 8.5(b) will be paid substantially concurrently with such termination, (2) pursuant to clause (ii) of this Section 8.5(b) will be paid no later than two (2) Business Days after such termination and (3) pursuant to clause (iii) of this Section 8.5(b) will be payable to Parent upon consummation of the Contemplated Transactions. The Company will not be required to pay the termination fee pursuant to this Section 8.5(b) more than once.

(c) In the event the termination fee payable pursuant to Section 8.5(b) is paid to Parent in accordance with Section 8.5(b), (i) Parent’s receipt of the termination fee shall be the sole and exclusive remedy of Parent and Purchaser in respect of any breach of, or inaccuracy contained in, the Company’s covenants, agreements, representations or warranties in this Agreement and (ii) none of the Parent, Purchaser, any of their respective Affiliates or any other Person shall be entitled to bring or maintain any other claim, action or proceeding against the Company or any of its Affiliates or any Representative of the Company or any of its Affiliates arising out of this Agreement, any of the Contemplated Transactions or any matters forming the basis for such termination; provided that nothing in this Section 8.5(c) shall relieve the Company from liability for damages arising from an Intentional Breach of Section 6.3(a).

(d) The Company acknowledges that the agreements contained in Section 8.5(b) are an integral part of the Contemplated Transactions, and that, without these agreements, Parent and Purchaser would not have entered into this Agreement. Accordingly, if the Company fails to promptly pay the amount due pursuant to Section 8.5(b) when due and, in order to obtain such payment, Parent or Purchaser commences a suit that results in a judgment against the Company for the amount set forth in Section 8.5(b), the Company shall pay to Parent or Purchaser interest on such amount at the prime rate as published in The Wall Street Journal in effect on the date such payment was required to be made through the date of payment.

(e) The Parties intend that any payment of the termination fee payable pursuant to Section 8.5(b) shall be compensatory in nature and shall not be treated (in whole or in part) as consideration for a supply for the purposes of VAT and, accordingly, the Company shall pay the full amount of any such termination fee free and clear of any withholdings, deductions or adjustments. To the extent that it is determined by a Tax Authority that such termination fee constitutes all or part of the consideration for a taxable supply made for VAT purposes, then the Purchaser shall issue a VAT invoice to the Company and the Company shall pay any VAT due in addition to the termination fee.

Section 8.6. Expenses; Transfer Taxes. Except as otherwise specifically provided herein, each Party shall bear its own expenses in connection with this Agreement and the Contemplated Transactions. All United Kingdom stamp duty and stamp duty reserve tax and any other similar transfer Taxes incurred in connection with the transfer of the Scheme Shares pursuant to this Agreement (the “Transfer Taxes”) shall be paid by Purchaser. Purchaser shall prepare and file, at its expense, all necessary documentation with respect to such Transfer Taxes.

Section 8.7. Amendment and Waiver. This Agreement may not be amended except by an instrument in writing signed by the Parties prior to the Effective Time. At any time prior to the Effective Time, the Company, on the one hand, and Parent and Purchaser, on the other hand, may (a) extend the time for the performance of any of the obligations or other acts of the other, (b) waive any inaccuracies in the representations and warranties of the other contained herein or in any document delivered pursuant hereto and (c) subject to the requirements of applicable Law, waive compliance by the other with any of the agreements or conditions contained herein. Any such extension or waiver will be valid only if set forth in an instrument in writing signed by the Party or Parties to be bound thereby. The failure of any Party to assert any rights or remedies will not constitute a waiver of such rights or remedies.

ARTICLE IX

None of the representations, warranties, covenants and agreements in this Agreement or in any instrument delivered pursuant to this Agreement, including any rights arising out of any breach of such representations, warranties, covenants and agreements, will survive the Effective Time, except for (a) those covenants and agreements contained herein that by their terms apply or are to be performed in whole or in part after the Effective Time and (b) this Article IX.

ARTICLE II

CONTINGENT VALUE RIGHTS

Section 2.1 CVRs. Each CVR represents the contractual right of a Holder to receive the applicable Milestone Payment(s) subject to, if it occurs, achievement of the applicable Milestone(s), in all cases pursuant to, and subject to the terms and conditions of, this Agreement. For clarity, (i) if the IH Milestone is achieved prior to the earlier of the Indication Milestone Expiration and the Termination, both the IH Milestone Payment and the Indication Milestone Payment will become due and payable in accordance with this Agreement, (ii) if the NT2 Milestone is achieved prior to the earlier of the Indication Milestone Expiration and the Termination, both the NT2 Milestone Payment and the Indication Milestone Payment will become due and payable in accordance with this Agreement, and (iii) if both the IH Milestone and NT2 Milestone are achieved prior to the earlier of the Indication Milestone Expiration and the Termination, the Indication Milestone Payment, IH Milestone Payment and NT2 Milestone Payment will become due and payable in accordance with this Agreement; provided, however, in the event all three Milestones are achieved as described in this clause (iii), the Indication Milestone Payment will become payable only once upon the first achievement of the associated Milestone (including with respect to either IH or NT2 if either is met in accordance with the terms of the Agreement as set forth in this clause (iii)) and no amounts will be due for subsequent or repeated achievements of any Milestone.

Section 2.2 Nontransferable. The CVRs shall not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted CVR Transfer; the foregoing restrictions shall apply notwithstanding that certain of the CVRs will be held through DTC. Any attempted sale, assignment, transfer, pledge, encumbrance or disposition of CVRs, in whole or in part, in violation of this Section 2.2 shall be void ab initio and of no effect. The CVRs will not be listed on any quotation system or traded on any securities exchange.

Section 2.3 No Certificate; Registration; Registration of Transfer; Change of Address.

(a) The CVRs will be issued in book entry format and will not be evidenced by a certificate or other instrument.

(b) The Rights Agent will create and maintain a register (the “CVR Register”) for the purpose of registering CVRs and Permitted CVR Transfers as provided herein. In the case of CVRs to be received by the holders of Company Covered Awards pursuant to the Transaction Agreement or CVRs to be received by registered holders of Scheme Shares (other than the Depositary Shares [and Company Covered Awards granted in respect of Depositary Shares]), such CVRs shall initially be registered in the name and address of the holder of such Company Covered Awards or registered holder of Scheme Shares, as applicable, as set forth in the records of Company at the Effective Time; provided that the CVR Register shall include, and shall be updated at each applicable Milestone Payment Date, with respect to the holders of Company Covered Awards, such Holder’s employment status with the Company. [In the case of CVRs to be received by the Depositary in respect of the Depositary Shares [and Company Covered Awards granted in respect of Depositary Shares], (i) the CVR Register will initially show one position for Cede & Co. (as nominee of DTC) representing all of the CVRs that are distributed in respect of Company ADSs held through DTC on behalf of the Beneficial Owners (as defined in the Deposit Agreement) of such Company ADSs (“CVR Beneficial Owners”) and (ii) the CVR Register shall be updated to reflect the distribution of such CVRs to the Eligible Company ADS Holders as set forth in the records of the Depositary in accordance with instructions of the Depositary. Only Holders of CVRs registered on the CVR Register shall be entitled to any CVRs or rights as Holders under this Agreement. For the avoidance of doubt, Parent and its Affiliates (including Purchaser) and the Rights Agent will have no responsibility whatsoever directly to the CVR Beneficial Owners or any DTC participants, including with regard to the distribution of payments, unless and until such Persons are registered as Holders on the CVR Register.]⁵

⁵	Note to Draft: To be discussed and confirmed with Depositary and Computershare.

(c) Subject to the restrictions on transferability set forth in Section 2.2, every request made to transfer a CVR (including, for the avoidance of doubt, a transfer to CVR Beneficial Owners from Eligible Company ADS Holders) must be in writing and accompanied by a written instrument of transfer and other documentation reasonably requested by the Rights Agent or Parent, in form reasonably satisfactory to the Rights Agent pursuant to its guidelines, duly executed by the Holder thereof, the Holder’s attorney duly authorized in writing, the Holder’s personal representative duly authorized in writing, or the Holder’s survivor (with written documentation evidencing such person’s status as the Holder’s survivor), and setting forth in reasonable detail the circumstances relating to the requested transfer. Upon receipt of such written notice, the Rights Agent will, subject to its reasonable determination that the transfer instrument is in proper form and the transfer otherwise complies with the other terms and conditions of this Agreement (including the provisions of Section 2.2), register the transfer of the CVRs in the CVR Register. As a condition of such transfer, Parent and the Rights Agent may require a transferring Holder or its transferee to pay to the applicable Governmental Body any transfer, stamp or other similar Tax or governmental charge that is imposed in connection with any such registration of transfer. The Rights Agent shall have no duty or obligation to take any action under any Section of this Agreement that requires the payment by a Holder of a CVR of such applicable Taxes or charges unless and until the Rights Agent is reasonably satisfied that all such Taxes or charges have been paid or that such Taxes or charges are not applicable. All CVRs duly transferred in accordance with Section 2.2 that are registered in the CVR Register will be the valid obligations of Parent and Purchaser and will entitle the transferee to the same benefits and rights under this Agreement as those held immediately prior to the transfer by the transferor. No transfer of a CVR will be valid until registered in the CVR Register in accordance with this Agreement.

(d) A Holder may make a written request to the Rights Agent to change such Holder’s address of record in the CVR Register. The written request must be duly executed by the Holder. Upon receipt of such written notice, the Rights Agent will promptly record the change of address in the CVR Register.

Section 2.4 Payment Procedures; Notices.

(a) If a Milestone is achieved prior to the applicable Milestone Expiration for such Milestone and before the Termination, then on or prior to the date that is twenty (20) Business Days following the achievement of such Milestone (such date, the “Milestone Payment Date”), (i) Parent shall deliver to the Rights Agent (x) a written notice indicating that such Milestone has been achieved (the “Milestone Notice”), (y) an Officer’s Certificate certifying the date of such achievement and a statement that the Holders are entitled to receive the applicable Milestone Payment and (z) a letter of instruction reasonably required by the Rights Agent, which shall set forth the applicable Milestone Payment in respect of such Milestone as of the date of the Milestone Notice, and shall include confirmation of the Holders of Company Covered Awards who shall be paid through the Company’s payroll, and (ii) Parent shall, or shall cause Purchaser or its Affiliate to, deliver to Computershare (or to Parent, the Company or their Affiliates, as applicable, in the case of payments with respect to Equity Award CVRs) the payment required by Section 4.2, if being delivered to Computershare to the account set forth on Annex I hereto, which account information may be updated from time to time by Computershare by prior written notice to Parent and Purchaser (the “Rights Agent Account”). For the avoidance of doubt, for all

purposes under this Agreement, each Milestone Payment shall only be due once, if at all, subject to the conditions set forth herein, including the achievement of the applicable Milestone prior to the earlier of the applicable Milestone Expiration and the Termination, and the maximum aggregate potential amount payable under this Agreement shall be $2.00 with respect to the NT2 Milestone, $5.00 with respect to the IH Milestone and $2.00 with respect to the Indication Milestone, in each case, subject to achievement of the applicable Milestone prior to the earlier of the applicable Milestone Expiration and the Termination. If a Milestone has not been achieved prior to the earlier of the applicable Milestone Expiration and the Termination, then Purchaser will not be required to make any payment to the Rights Agent or the Holders pursuant to this Agreement in respect of such Milestone.

(b) The Rights Agent will promptly, and in any event within ten (10) Business Days of receipt of a Milestone Notice as well as any letter of instruction as required by the Rights Agent, (i) send each Holder at its registered address (or, in the case of Cede & Co., pursuant to the applicable procedures of DTC) a copy of the Milestone Notice and (ii) pay the applicable Milestone Payment Amount (excluding certain Equity Award CVR Payments to be paid via payroll systems as contemplated below) to each of the Holders (x) with respect to any holder of Remnant Shares or holder of Equity Award CVRs that is not an employee of the Company or its Affiliates as of such date, by check mailed to the address of each such Holder as reflected in the CVR Register as of 5:00 p.m. U.S. Eastern Time on the date of the applicable Milestone Notice, (y) with respect to any such Holder that is due an amount in excess of $100,000 in the aggregate who has provided the Rights Agent wiring instructions in writing as of the close of business on the date of applicable Milestone Notice, by wire transfer of immediately available funds to the account specified on such instructions or (z) with respect to Cede & Co., by wire transfer of immediately available funds pursuant to the applicable procedures of DTC. Parent will, or will cause Purchaser to, pay the applicable Milestone Payment Amount to each holder of Equity Award CVRs who remains employed by the Company or its Affiliates as of such date within ten (10) Business Days of delivery of a Milestone Notice to the Rights Agent through the Company’s or its Affiliates’ (including Purchaser’s, the Company’s or any of their respective Subsidiaries’) payroll system or any successor system for former employees, subject to Section 2.4(c) of this Agreement.

(c) Parent and its Affiliates (including Purchaser) and the Rights Agent shall deduct and withhold from any Milestone Payment Amount or any other amounts otherwise payable pursuant to this Agreement such amounts, including for or in respect of Tax, as are required to be deducted and withheld therefrom under applicable Law (including, but not limited to, employee National Insurance Contributions in the United Kingdom or any similar social security contribution in any other jurisdiction). With respect to holders of Equity Award CVRs who remain employed by the Company or its Affiliates as of the applicable Milestone Payment Date, any such withholding shall be effected, or caused to be effected, by Parent through the Company’s or its Affiliates’ (including Purchaser’s, the Company’s or any of their respective Subsidiaries’) payroll system, as relevant, or any successor payroll system. Prior to paying any Milestone Payment Amount to the Holders, the Rights Agent shall provide the opportunity for each Holder to provide a copy of a duly executed IRS Form W-9 or appropriate IRS Form W-8, as applicable, or any other forms or information that the Rights Agent may reasonably request in order to avoid or reduce

any applicable withholding amount. The Rights Agent shall promptly and timely remit, or cause to be remitted, any amounts deducted or withheld in respect of Taxes to the appropriate Governmental Body (except to the extent such amounts have already been withheld or deducted and processed through payroll systems in accordance with this Section 2.4(c)). To the extent any amounts are so deducted and withheld and properly remitted, such amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of whom such deduction and withholding was made. The parties intend that each Equity Award CVR is exempt from or in compliance with Section 409A of the Code, and this Agreement shall be interpreted and administered in accordance therewith. None of the Parties or any of their employees, directors or representatives shall have any liability to a Holder or transferee or other Person in respect of Section 409A of the Code.

(d) Any portion of a Milestone Payment Amount that remains undistributed six (6) months after the date of the delivery of the applicable Milestone Notice will be delivered by the Rights Agent to Parent or Purchaser, upon demand, and any Holder will thereafter look only to Parent and Purchaser for payment of the applicable Milestone Payment Amount, without interest, but such Holder will have no greater rights against Parent and Purchaser than those accorded to general unsecured creditors of Parent and Purchaser under applicable Law.

(e) None of Parent, any of its Affiliates (including Purchaser) or the Rights Agent will be liable to any person in respect of any Milestone Payment Amount or portion thereof delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If, despite efforts by the Rights Agent to deliver such Milestone Payment Amount to the applicable Holder pursuant to the Rights Agent’s customary unclaimed funds procedures, such Milestone Payment Amount has not been paid prior to the two (2) year anniversary of the applicable Milestone Payment Date (or immediately prior to such earlier date on which such Milestone Payment Amount would otherwise escheat to or become the property of any Governmental Body), such Milestone Payment Amount will, to the extent permitted by applicable Law, become the property of Purchaser, free and clear of all claims or interest of any person previously entitled thereto. In addition to and not in limitation of any other indemnity obligation herein, Purchaser agrees to indemnify and hold harmless the Rights Agent with respect to any liability, penalty, cost or expense the Rights Agent may incur or be subject to in connection with transferring such property to Purchaser.

(f) The Rights Agent shall be responsible for information reporting required under applicable Law with respect to the CVRs, including reporting the fair market value of the CVRs upon the Holders’ receipt of such CVRs on Internal Revenue Service Form 1099-B and reporting any Milestone Payments hereunder on Internal Revenue Service Form 1099-B or other applicable form to the extent required under applicable Law. The Rights Agent shall use commercially reasonable efforts to cooperate with Purchaser for reporting the fair market value of the CVR to Holders of CVRs (other than Equity Award CVRs) that are subject to U.S. federal income taxes and that the Rights Agent is not required by applicable Law to report such amount on Internal Revenue Service Form 1099-B or other applicable form. Purchaser shall provide the Rights Agent with properly

completed “Standard Tax Reporting Instructions” contained in Annex II hereto, which shall contain the fair market value of the CVRs and Purchaser shall use commercially reasonable efforts to cooperate with the Rights Agent to provide any other information reasonably necessary for the Rights Agent to carry out its obligations in this Section 2.4(f).

Section 2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest in Parent or any of its Affiliates.

(a) The CVRs will not have any voting or dividend rights, and interest will not accrue on any amounts payable on the CVRs to any Holder.

(b) The CVRs will not represent any equity or ownership interest in Parent, any constituent corporation party to the Transaction Agreement or any of their respective Affiliates or Subsidiaries (including Purchaser).

(c) Neither Parent or its directors and officers nor Purchaser or its directors and officers will be deemed to have any fiduciary or similar duties to any Holder by virtue of this Agreement or the CVRs.

Section 2.6 Holding of Funds. All funds received by Computershare under this Agreement that are to be distributed or applied by Computershare in the performance of its services hereunder (the “Funds”) shall be held by Computershare as agent for Parent and deposited in one or more segregated bank accounts to be maintained by Computershare in its name as agent for Parent. Until paid pursuant to the terms of this Agreement, Computershare will hold the Funds through such accounts in deposit accounts of commercial banks with Tier 1 capital exceeding $1 billion or with an average rating above investment grade by S&P (LT Local Issuer Credit Rating), Moody’s (Long Term Rating) and Fitch Ratings, Inc. (LT Issuer Default Rating) (each as reported by Bloomberg Finance L.P.). Computershare shall have no responsibility or liability for any diminution of the Funds that may result from any deposit made by Computershare in accordance with this Section 2.6, including any losses resulting from a default by any bank or financial institution; provided that in the event the Funds are diminished below the level required for Computershare to make the Milestone Payment Amounts (to the extent remaining due) to Holders (other than Holders of Equity Award CVRs who are to be paid via payroll as set forth in Section 2.4(c)), as required under this Agreement, including any such diminishment as a result of investment losses, Parent shall promptly pay additional cash to Computershare in an amount equal to the deficiency in the amount required to make such payments. Computershare may from time to time receive interest, dividends or other earnings in connection with such deposits. Computershare shall not be obligated to pay such interest, dividends or earnings to Parent, any Holder or any other Person.

Section 2.7 No Assurance. It is hereby acknowledged and agreed that the CVRs and the possibility of any payment hereunder with respect thereto are highly speculative and subject to numerous factors outside of the control of Parent, Purchaser, the Company and their respective Affiliates, and there is no assurance that Holders will receive any payments under this Agreement or in connection with the CVRs. By accepting one or more CVRs, each Holder is deemed to acknowledge that it is highly possible that the Milestones will not occur. Each Holder is further deemed to acknowledge and agree that none of Parent, Purchaser, the Company nor their respective

Affiliates owe, by virtue of their obligations under this Agreement, a fiduciary duty or any implied duties to the Holders or the Rights Agent, and Parent, Purchaser, the Company and their respective Affiliates intend solely that the express provisions of this Agreement govern their contractual relationship with respect to the CVRs. It is acknowledged and agreed that this Section 2.7 is an essential and material term of this Agreement.

Section 2.8 Ability to Abandon CVR. A Holder may at any time, at such Holder’s option, abandon all of such Holder’s remaining rights in a CVR by transferring such CVR to Parent without consideration therefor, which a Holder may effect via delivery of a written abandonment notice to Parent. Nothing in this Agreement shall prohibit Parent or any of its Affiliates (including Purchaser) from offering to acquire or acquiring any CVRs for consideration from the Holders, in private transactions or otherwise, in its or their sole discretion. Any CVRs acquired by Parent or any of its Affiliates (including Purchaser) shall be automatically deemed extinguished and no longer outstanding or entitled to the Milestone Payments for purposes of this Agreement, or to count for the purpose of any vote or determination of Acting Holders for purposes of this Agreement.

Section 2.9 Tax Treatment. The Parties agree to treat the CVRs (other than the Equity Award CVRs) for all U.S. federal, and applicable state and local income Tax purposes as (x) except to the extent treated as imputed interest, additional consideration for, or in respect of, the Company Shares, and (y) a “closed transaction” in which the fair market value of the CVRs, as determined by Purchaser in its sole discretion, is included in income in the taxable year of the Closing, and, in each case, none of the Parties (and none of the applicable Holders of CVRs (other than the Equity Award CVRs)) will take any position to the contrary on any Tax Return, any other filing with a Governmental Body, in each case, related to U.S. federal, and applicable state and local income Tax purposes, except as otherwise required by a Final Determination. Purchaser, Parent, the Company or the Rights Agent, as applicable, shall report imputed interest on the CVRs pursuant to Section 483 of the Code, to the extent required by applicable Law and in accordance with properly completed “Standard Tax Reporting Instructions” contained in Annex II hereto.

THE RIGHTS AGENT

Section 3.1 No Liability. The Rights Agent will not have any liability for any actions taken or not taken in connection with this Agreement, except to the extent such liability arises as a result of its willful or intentional misconduct, bad faith, fraud or gross negligence (in each case as determined by a final non-appealable judgment of a court of competent jurisdiction). Notwithstanding anything in this Agreement to the contrary, other than in the case of willful or intentional misconduct, bad faith, fraud or gross negligence (in each case, as determined by a final non-appealable judgment of a court of competent jurisdiction), any liability of the Rights Agent under this Agreement will be limited to two (2) times the amount of fees paid (but not including reimbursable expenses) in the twelve (12) months preceding the event for which recovery is sought in connection with this Agreement. Anything to the contrary notwithstanding, in no event will the Rights Agent be liable for special, punitive, indirect, incidental or consequential loss or damages of any kind whatsoever (including, without limitation, lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damages, and regardless of the form of action.

Section 3.2 Certain Duties and Responsibilities. The Rights Agent shall not have any duty or responsibility in the case of the receipt of any written demand from any Holder with respect to any action or default by any person or entity, including, without limiting the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at Law or otherwise or to make any demand upon Parent or Purchaser; provided that this Section 3.2 shall not affect the Rights Agent’s obligation to make payments in accordance with and subject to Section 2.4.

(ii) whenever the Rights Agent will deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Rights Agent may rely upon an Officer’s Certificate, which certificate shall be full authorization and protection to the Rights Agent, and the Rights Agent shall, in the absence of bad faith, fraud, gross negligence or willful or intentional misconduct (each as determined by a final non-appealable judgment of a court of competent jurisdiction) on its part, incur no liability and be held harmless by Parent for or in respect of any action taken, suffered or omitted to be taken by it under the provisions of this Agreement in reliance upon such certificate;

(iii) the Rights Agent may engage and consult with counsel of its selection and the written advice of such counsel or any opinion of counsel will be full and complete authorization and protection to the Rights Agent and the Rights Agent shall be held harmless by Parent in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon and that does not constitute gross negligence or willful or intentional misconduct;

(iv) the permissive rights of the Rights Agent to do things enumerated in this Agreement will not be construed as a duty;

(v) the Rights Agent will not be required to give any note or surety in respect of the execution of such powers or otherwise in respect of the premises;

(vi) the Rights Agent shall not be liable for or by reason of, and shall be held harmless by Parent with respect to, any of the statements of fact or recitals contained in this Agreement or be required to verify the same, but all such statements and recitals are and shall be deemed to have been made by Parent only;

(viii) Parent agrees to indemnify the Rights Agent for, and hold the Rights Agent harmless against, any loss, liability, damage, judgment, fine, penalty, claim, demands, suits or expense arising out of or in connection with the Rights Agent’s performance of its duties under this Agreement (excluding any Taxes imposed on the fees owed to the Rights Agent hereunder), including the reasonable and documented out-of-pocket costs and expenses of defending the Rights Agent against any claims, charges, demands, suits or loss arising out of or in connection with the execution, administration, exercise and performance of its duties under this Agreement, including the reasonable and documented out-of-pocket costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly, or enforcing its rights hereunder, unless such loss has been determined by a court of competent jurisdiction to have resulted from the Rights Agent’s willful or intentional misconduct, bad faith, fraud or gross negligence;

(ix) Parent agrees (x) to pay the fees and expenses of the Rights Agent in connection with this Agreement, as agreed upon in writing in a fee schedule by the Rights Agent and Parent on or prior to the date hereof, which shall include reimbursement from Parent, for all reasonable, documented and necessary out-of-pocket expenses and disbursements paid or incurred in the preparation, delivery, negotiation, amendment, administration and execution of this Agreement and the exercise and performance by the Rights Agent of its duties hereunder and (y) to reimburse the Rights Agent for all Taxes and governmental charges (other than Taxes imposed on or measured by the Rights Agent’s net income and franchise or similar Taxes imposed on it (in lieu of net income Taxes)); provided that if the Rights Agent determines in the absence of bad faith that it has received a refund of any Tax or governmental charge borne by Parent pursuant to this clause (y), the Rights Agent shall promptly repay such refund to Parent;

(x) no provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if it reasonably believes that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it;

(xi) in the event the Rights Agent reasonably believes any ambiguity or uncertainty exists hereunder or in any notice, instruction, direction, request or other communication, paper or document received by the Rights Agent hereunder, the Rights Agent shall, as soon as practicable, provide written notice to Parent describing in detail the ambiguity or uncertainty it believes exists, and the Rights Agent shall seek clarification. Parent will respond to such request for clarification

as promptly as reasonably practicable, and in any event within ten (10) Business Days. If such clarification is not provided within ten (10) Business Days, the Rights Agent may, in its sole discretion, refrain from taking any action, and shall be fully protected and shall not be liable in any way to Parent or any Holder or any other Person for refraining from taking such action, unless and until the Rights Agent receives written instructions from Parent which reasonably eliminate such ambiguity or uncertainty;

(xii) the Rights Agent shall not be deemed to have knowledge of any event of which it was entitled to receive notice pursuant to the terms of this Agreement, and the Rights Agent shall be fully protected and shall incur no liability for failing to take action in connection with such event, in each case, unless and until such notice has been given in accordance with Section 6.1;

The Rights Agent shall be under no responsibility for the validity or sufficiency of this Agreement with respect to any other Party or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of the CVRs, nor shall it be responsible for any breach by Parent or Purchaser of any covenant or condition contained in this Agreement or any CVR.

(b) The obligations of Parent and the rights of the Rights Agent under this Section 3.3, Section 3.1 and Section 3.2 shall survive the Milestone Expirations and the termination of this Agreement and the resignation, replacement or removal of the Rights Agent.

Section 3.4 Resignation and Removal; Appointment of Successor.

(a) The Rights Agent may resign at any time by giving written notice thereof to Parent specifying a date when such resignation will take effect, which notice will be sent at least thirty (30) days prior to the date so specified and such resignation will become effective on the date so specified. Parent has the right to remove Rights Agent at any time by specifying a date when such removal will take effect and such removal will become effective on the date so specified. Notice of such removal will be given by Parent to Rights Agent, which notice will be sent at least sixty (60) days prior to the date so specified.

(b) If the Rights Agent provides notice of its intent to resign, is removed pursuant to Section 3.4(a) or becomes incapable of acting, Parent will as soon as is reasonably possible, appoint a qualified successor Rights Agent who, unless otherwise consented to in writing by the Acting Holders, shall be a stock transfer agent of national reputation or the corporate trust department of a commercial bank. The successor Rights Agent so appointed will, forthwith upon its acceptance of such appointment in accordance with Section 3.5, become the successor Rights Agent.

Each notice will include the name and address of the successor Rights Agent. If Parent fails to send such notice within ten (10) Business Days after acceptance of appointment by a successor Rights Agent in accordance with Section 3.5, the successor Rights Agent will cause the notice to be mailed at the expense of Parent; provided that failure to give any notice provided for in this Section 3.4(a) shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be, in each case, in accordance with this Section 3.4.

(d) The Rights Agent will reasonably cooperate with Parent and any successor Rights Agent as reasonably requested in connection with the transition of the duties and responsibilities of the Rights Agent to the successor Rights Agent, including transferring the CVR Register to the successor Rights Agent, but such predecessor Rights Agent shall not be required to make any additional expenditure without compensation or reimbursement by Parent or assume any additional liability in connection with the foregoing.

Section 6.2 Notice to Holders. Where this Agreement provides for notice to Holders, such notice will be sufficiently given (unless otherwise herein expressly provided) if in writing and transmitted through the facilities of DTC in accordance with DTC’s procedures (in respect of CVRs registered in the name of Cede & Co. only) or mailed, first-class postage prepaid, to each Holder affected by such event, at the Holder’s address as it appears in the CVR Register, not later than the latest date, and not earlier than the earliest date, if any, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder will affect the sufficiency of such notice with respect to other Holders.

Section 6.3 Successors and Assigns.

(a) Each of Parent and Purchaser may assign any or all of its rights, interests and obligations hereunder in its sole discretion and without the consent of any other party, (i) to any wholly-owned Affiliate of Parent, but only for so long as it remains a controlled Affiliate of Parent; (ii) to any purchaser, transferee, licensee, or sublicensee that is a company in the pharmaceutical industry, of substantially all of the Intellectual Property and other rights (including, without limitation, all data, marketing authorizations and applications for marketing authorization), assets, rights, powers, privileges and Contracts, in each case, (A) held, owned or entered into by Parent or its Subsidiaries immediately after the Effective Time and (B) necessary for the production, development or sale of the CVR Product; (iii) in compliance with Section 4.3(b); or (iv) otherwise with the prior written consent of the Acting Holders, to any other Person (any permitted assignee under clause (i), (ii), (iii) or (iv), an “Assignee”), in each case, provided that the Assignee agrees in writing to assume and be bound by all of the terms of this Agreement. Any Assignee may thereafter assign any or all of its rights, interests and obligations hereunder in the same manner as Parent or Purchaser, as applicable, pursuant to the prior sentence. In connection with any assignment to an Assignee described in clause (i) above in this Section 6.3, each of Parent or Purchaser, as applicable, (and the other assignor) shall agree to remain liable for the performance by each Assignee (and such other assignor, if applicable) of all obligations of Parent or Purchaser, as applicable, hereunder with such Assignee substituted for Parent or Purchaser, as applicable, under this Agreement. This Agreement will be binding upon, inure to the benefit of and be enforceable by each of Parent’s successors and each Assignee and each of Purchaser’s successors and each Assignee, as applicable. Subject to compliance with the requirements set forth in this Section 6.3 relating to assignments and Section 4.3(b), this Agreement shall not restrict Parent’s, Purchaser’s, any Assignee’s or any of their respective successors’ ability to merge or consolidate with, or sell, issue, license or dispose of its stock or other equity interests or assets to, any other Person, or spin-off or split-off. Each of Parent’s successors and Assignees, and each of Purchaser’s successors and Assignees, as applicable, shall expressly assume by an instrument supplemental hereto, executed and delivered to the Rights Agent, the due and punctual payment of the CVRs and the due and punctual performance and observance of all of the covenants and obligations of this Agreement to be performed or observed by Parent or Purchaser, as applicable.

(b) The Rights Agent may not assign this Agreement without Parent’s written consent other than as permitted by this Section 6.3(b). Any attempted assignment of this Agreement or any such rights in violation of this Section 6.3(b) shall be void and of no effect. Any Person into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or Person resulting from any merger or

consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any Person succeeding to the stock transfer or other shareholder services business of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the Parties; provided that such Person would be eligible for appointment as a successor Rights Agent under the provisions of Section 3.4(b). The purchase of all or substantially all of the Rights Agent’s assets employed in the performance of transfer agent activities shall be deemed a merger or consolidation for purposes of this Section 6.3(b).

Section 6.4 Benefits of Agreement. Nothing in this Agreement, express or implied, will give to any Person (other than the Rights Agent, Parent, Parent’s successors and Assignees, Purchaser, Purchaser’s successors and Assignees, the Holders and the Holders’ successors and assigns pursuant to a Permitted CVR Transfer) any benefit or any legal or equitable right, remedy or claim under this Agreement or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the foregoing. The rights of Holders and their successors and assigns pursuant to Permitted CVR Transfers are limited to those expressly provided in this Agreement. Notwithstanding anything to the contrary contained herein, any Holder or Holder’s successor or assign pursuant to a Permitted CVR Transfer may agree to renounce, in whole or in part, its rights under this Agreement by written notice to the Rights Agent and Parent, which notice, if given, shall be irrevocable. Except for the rights and immunities of the Rights Agent set forth herein, the Acting Holders will have the sole right, on behalf of all Holders, by virtue of or under any provision of this Agreement, to institute any action or proceeding with respect to this Agreement, and no individual Holder or other group of Holders will be entitled to exercise such rights (provided that the foregoing shall not limit the ability of an individual Holder to seek a payment due from the applicable party pursuant to Section 4.2 solely to the extent such payment amount has been finally determined in accordance with this Agreement and has not been paid within the period contemplated by this Agreement). Reasonable expenditures incurred by such Holders in connection with any enforcement action hereunder may be deducted from any damages or settlement obtained prior to the distribution of any remainder to Holders generally. The Acting Holders acting pursuant to this provision on behalf of all Holders shall have no liability to any of the Holders for such actions. For the avoidance of doubt, for all purposes under this Agreement, each Milestone shall be treated independently for all purposes of this Agreement (including for purposes of determining liability, damages, and any other remedies), and no claim by any Holder or group of Holders alleging a breach of Section 4.3(a) or any other provision of this Agreement with respect to a particular Milestone shall entitle such Holder or Holders to damages measured by reference to, or otherwise based upon, the Milestone Payment applicable to any other Milestone. Any damages recoverable by any Holder or group of Holders in connection with a breach of this Agreement with respect to a particular Milestone shall be limited solely to the applicable Milestone Payment for such Milestone, and shall not include consequential, indirect, special, or punitive damages or damages attributable to any other Milestone or Milestone Payment.

Section 6.5 Governing Law; Jurisdiction; Waiver of Jury Trial.

(a) This Agreement will be governed by, and construed in accordance with, the Laws of the State of Delaware, regardless of the Laws that might otherwise govern under applicable principles of conflicts of laws thereof.

(b) Each of the Parties hereby (i) expressly and irrevocably submits to the exclusive personal jurisdiction of the Court of Chancery of the State of Delaware or if such Court of Chancery lacks subject matter jurisdiction, the United States District Court for the District of Delaware, in the event any dispute arises out of this Agreement or the transactions contemplated hereby, (ii) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court and (iii) agrees that it shall not bring any action relating to this Agreement or the transactions contemplated hereby in any court other than the Court of Chancery of the State of Delaware or if such Court of Chancery lacks subject matter jurisdiction, the United States District Court for the District of Delaware; provided that each of the Parties has the right to bring any action or proceeding for enforcement of a judgment entered by such court in any other court or jurisdiction.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION ARISING OUT OF, RELATING TO OR IN CONNECTION WITH THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT, OR ATTORNEY OF ANY PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATION OF THIS WAIVER, (III) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (IV) EACH OTHER PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 6.5(C).

SPECIAL RESOLUTION

THAT, for the purpose of giving effect to the scheme of arrangement, dated [•], among the Company and the holders of Scheme Shares (as defined in such scheme of arrangement), a print of which has been produced to this meeting and for the purposes of identification signed by the chair of this meeting, in its original form or with or subject to any modification, addition, or condition as may be agreed from time to time (including, for the avoidance of doubt, after the date of this Resolution), between the Company, LDH XV Corporation (the “Purchaser”) and Eli Lilly and Company (“Parent”) and which (if required) is approved by the High Court of Justice of England and Wales (the “Court”), or which is otherwise imposed by the Court and is mutually acceptable to the Company, the Purchaser and Parent each acting reasonably and in good faith (the “Scheme”):

(A)	the directors of the Company (or a duly authorised committee of the directors) be and are hereby authorised to take all such action as they may consider necessary or appropriate for carrying the Scheme into effect; and

(B)	with effect from the passing of this resolution, the articles of association of the Company be and are hereby amended by the adoption and inclusion of the following new article [•]:

“[•] Scheme of Arrangement

(i)

In this article, references to the “Scheme” are to the scheme of arrangement under Part 26 of the Companies Act 2006, among the Company and the holders of Scheme Shares dated [•] 2026 in its original form or with or subject to any modification, addition or condition as may be agreed between the Company, LDH XV Corporation] (the “Purchaser”) and Eli Lilly and Company (“Parent”), and which (if required) is approved by the Court, or which is otherwise imposed by the Court and is mutually acceptable to the Company, the Purchaser and Parent each acting reasonably and in good faith and, save as defined in this article, expressions defined in the Scheme shall have the same meanings in this article.

(ii)

Notwithstanding any other provision of these articles or the terms of any resolution, whether ordinary or special, passed by the Company in general meeting, if the Company issues any shares (other than to any member of the Purchaser Group or a nominee of any such person (each such person, a “Purchaser Company”)) at or after the Voting Record Time but before the Scheme Record Time, such shares shall be issued subject to the terms of the Scheme (and shall be Scheme Shares for the purposes of the Scheme) and the original or any subsequent holder or holders of such shares shall be bound by the Scheme accordingly.

(iii)

Subject to the Scheme becoming effective, and notwithstanding any other provision of these articles, if any shares in the Company are issued or transferred to any person other than a Purchaser Company (a “New Member”) after the Scheme Record Time (such shares the “Post-Scheme Shares”), such New Member (or any subsequent holder or any nominee of such New Member or any such subsequent holder) will be obliged, upon the Scheme becoming effective (or, if later, upon the issue or transfer of the Post-Scheme Shares to such New Member), to transfer immediately all of its Post-Scheme Shares free of all Liens to the Purchaser (or to such other person as may be nominated by the Purchaser) who shall be obliged to acquire (or procure the acquisition by such other person of) all of the Post-Scheme Shares. In exchange for the transfer of the Post-Scheme Shares, the Purchaser (or such other person as has been nominated by the Purchaser) shall pay or procure the payment to the New Member of the same Cash Consideration and deliver such number of CVRs as such New Member would have been entitled to receive pursuant to the Scheme had each Post-Scheme Share been a Scheme Share.

(iv)

If, after the Effective Time, the Company Shares shall have been changed to, or exchanged for, a different number or class of shares or securities by reason of any stock dividend, bonus issue, scrip dividend, subdivision, reorganisation, merger, consolidation, reclassification, redesignation, recapitalisation, share split, reverse share split, combination or exchange of shares, or a stock or scrip dividend shall be declared with a record date falling after the Effective Time, or any similar event shall have occurred, then the amount

of any Cash Consideration or CVRs due to a New Member for each Post-Scheme Share pursuant to Article [•](iii) above shall be adjusted by the directors of the Company in such manner as the auditors of the Company may determine to be appropriate to provide the Purchaser and the New Members holding any Post-Scheme Share(s) with the same economic effect as contemplated by the Scheme prior to such event. References in this article to shares shall, following such adjustment, be construed accordingly.

(v)

To give effect to any transfer of Post-Scheme Shares required by Article [•](iii) above, the Company may appoint any person as attorney and/or agent (the “agent”) for the New Member to execute and deliver as transferor a form of transfer or other instrument or instruction of transfer on behalf of the New Member (or any subsequent holder or any nominee of such New Member or any such subsequent holder) in favour of the Purchaser (or such other person as the Purchaser may nominate) and do all such other things and execute and deliver all such documents as may in the opinion of the agent be necessary or desirable to vest the Post-Scheme Shares in the Purchaser (or such other person as the Purchaser may nominate) and pending such vesting to exercise all such rights attaching to the Post-Scheme Shares as the Purchaser may direct. If an agent is so appointed, the New Member shall not thereafter be entitled to exercise any rights attaching to the Post-Scheme Shares unless so agreed in writing by the Purchaser, and the Company may send to the agent any notice, circular, warrant or other document or communication that may otherwise be required to be sent to the New Member as a member of the Company.

(vi)

The Company may give good receipt for the Cash Consideration and CVRs for the Post-Scheme Shares due to the New Member pursuant to Article [•](iii) above and may register the Purchaser (or such other person as the Purchaser may nominate) as holder of the Post-Scheme Shares and issue to it certificate(s) for the same. The agent shall be empowered to execute and deliver as transferor a form of transfer or other instrument or instruction of transfer on behalf of the New Member (or any subsequent holder). The Company shall not be obliged to issue a certificate to the New Member for any Post-Scheme Shares.

(vii)

The Purchaser shall settle (or procure the settlement of) the Cash Consideration and delivery of the CVRs due to the New Member pursuant to Article [•](iii) above within fourteen (14) days of the transfer of the Post-Scheme Shares by the New Member to the Purchaser (or to such other person as the Purchaser may nominate).

(viii)

Notwithstanding any other provision of these articles, neither the Company nor its directors shall register the transfer of any Scheme Shares effected between the Scheme Record Time and the Effective Time (other than to a Purchaser Company or a nominee of a Purchaser Company pursuant to the Scheme).

(ix)	If the Scheme has not become effective by the date referred to in paragraph [10.2] of the Scheme, this article shall cease to be of any effect.”

the Remnant Shares shall be transferred to Purchaser (and/or, at Parent’s election in respect of any number of Remnant Shares, its nominee(s)) by means of a separate form (or forms) of transfer or other separate instrument(s) or instruction(s) of transfer; and

1.2.3

to give effect to such transfers, any person may be appointed by Purchaser (and/or its nominee(s) and/or each of their agents and directors) as attorney or agent and shall be authorised as such attorney and/or agent on behalf of each of the Scheme Shareholders concerned to execute and deliver as transferor such form(s) of transfer or other instrument(s) or instruction(s) of transfer of, or otherwise give any instruction(s) to transfer (whether as a deed or otherwise) the Scheme Shares and every form, instrument or instruction of transfer so executed or instruction so given shall be as effective as if it had been executed or given by the holder or holders of the Scheme Shares thereby transferred. Each such form of transfer or other instrument or instruction shall be deemed to be the principal instrument of transfer of the relevant Scheme Shares.

1.3	From the Effective Time and pending the transfer of the Scheme Shares pursuant to paragraphs 1.1 and 1.2, each Scheme Shareholder:

1.3.1

irrevocably appoints Purchaser (and/or its nominee(s) and/or each of their agents and directors) as its attorney and/or agent:

(a)

to exercise or direct the exercise on its behalf of (in place of and to the exclusion of the relevant Scheme Shareholder) any voting rights attached to the Scheme Shares and any or all other rights and privileges attaching to the Scheme Shares (including the right to requisition the convening of a general meeting of the Company or of any class of its shareholders); and

(b)

to sign on behalf of such Scheme Shareholder such documents, and to do such things, as may, in the opinion of Purchaser and/or its nominee(s) and/or each of their respective agents and directors, be necessary or desirable in connection with the exercise of any voting rights and any or all rights and privileges attaching to such Scheme Shares (including, without limitation, any consent to short notice of a general or separate class meeting or form of proxy or forms of proxy in respect of such Scheme Shares appointing any person nominated by Purchaser and/or its nominee(s) and/or any one or more of its directors or agents to attend general and separate class meetings of the Company (or any postponement, adjournment or reconvening therefore);

1.4	The authorities granted by each Scheme Shareholder pursuant to paragraphs 1.2 and 1.3 above shall be treated for all purposes as having been granted by deed.

2.	Consideration for the Scheme Shares

2.1	In consideration for the transfer of the Scheme Shares as provided in paragraphs 1.1 and 1.2 above, Purchaser shall, subject as hereinafter provided:

2.1.1

pay, or procure that there shall be paid, a cash amount to or for the account of each Scheme Shareholder of $38.00 in cash, without interest, for each Scheme Share held by that Scheme Shareholder at the Scheme Record Time (the “Cash Consideration”); and

2.1.2

cause to be provided to or for the account of each eligible Scheme Shareholder one (1) CVR per Scheme Share, upon the terms and subject to the conditions of the CVR Agreement, without interest (the CVRs and the Cash Consideration together, the “Transaction Consideration”). The CVRs are not securities and will not represent any equity or ownership interest in Parent, Purchaser or any constituent entity party to the Transaction Agreement, and accordingly will not confer on the CVR Holders any right to attend, speak at or vote at any meeting of the shareholders of Parent or Purchaser or the right to any dividends or right to any return of capital by Parent or Purchaser. Pursuant to the terms of the CVR Agreement, eligible Scheme Shareholders will receive one CVR for each Scheme Share that they hold. The CVRs will not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than to certain permitted transferees as specifically set forth in the CVR Agreement. The CVRs will not be listed on any quotation system or traded on any securities exchange. The CVRs will not be evidenced by a certificate or other document of title.

2.2

If, between the date of the Transaction Agreement and the Effective Time, the outstanding Company Shares shall have been changed to, or exchanged for, a different number or class of shares or securities by reason of any share dividend, bonus issue, scrip dividend, subdivision, reorganisation, merger, consolidation, reclassification, redesignation, recapitalisation, share split, reverse share split, combination or exchange of shares, or a stock or scrip dividend shall be declared with a record date within such period, or any similar event shall have occurred, then the amount of the Transaction Consideration shall be appropriately adjusted to provide to Purchaser and the Scheme Shareholders the same economic effect as contemplated by the Transaction Agreement prior to such event; provided that the Company is not permitted to take any action with respect to its securities that is prohibited by the Transaction Agreement. For the avoidance of doubt, any reference in this Scheme to the consideration payable under the Scheme shall be deemed a reference to the consideration as so adjusted, and the exercise of such rights shall not be regarded as constituting any revision or variation of the terms of this Scheme.

3.	Share certificates and register of Members

3.1

With effect from and as of the Effective Time, all certificates representing Scheme Shares in certificated form shall cease to have effect as documents of title to the Scheme Shares comprised therein and each Scheme Shareholder shall be bound, at the request of Purchaser, to deliver up the same to Purchaser or to any person appointed by Purchaser to receive the same or, as Purchaser may direct, to destroy the same.

3.2
