We have accomplished a tremendous amount for patients, their families and our customers, and created significant value for shareholders. These accomplishments are all rooted in our employees' deep commitment, dedication and personal passion for those impacted by rare, autoimmune and severe inflammatory diseases. Amgen is aligned with that commitment and passion and will continue to maximise the value of the current portfolio and pipeline and accelerate the ability to reach more patients globally."

• Commenting on today's announcement, Robert A. Bradway , chairman and chief executive officer of Amgen said:

" The acquisition of Horizon is a compelling opportunity for Amgen and one that is consistent with our strategy of delivering long-term growth by providing innovative medicines that address the needs of patients who suffer from serious diseases. Amgen's decades of leadership in inflammation and nephrology, combined with our global presence and world-class biologics capabilities, will enable us to reach many more patients with first-in-class medicines like TEPEZZA, KRYSTEXXA and UPLIZNA. Additionally, the potential new medicines in Horizon's pipeline strongly complement our own R&D portfolio. The acquisition of Horizon will drive growth in Amgen's revenue and non-GAAP EPS and is expected to be accretive from 2024."

Amgen Background to and Reasons for the Acquisition

Amgen believes that there is a compelling strategic and financial rationale for undertaking the Acquisition, which is expected to deliver the following benefits:

DISCLOSURE REQUIREMENTS OF THE IRISH TAKEOVER RULES

Under the provisions of Rule 8.3(a) of the Irish Takeover Rules, any person who is 'interested' in 1% or more of any class of 'relevant securities' of the Company must make an 'opening position disclosure' following the commencement of the 'offer period'. An 'opening position disclosure' must contain the details contained in Rule 8.6(a) of the Irish Takeover Rules, including, among other things, details of the person's 'interests' and 'short positions' in any 'relevant securities' of the Company. An 'opening position disclosure' by a person to whom Rule 8.3(a) applies must be made by no later than 3:30 p.m. (E.T.) on the day falling ten 'business days' following the commencement of the 'offer period'. Relevant persons who deal in any 'relevant securities' prior to the deadline for making an 'opening position disclosure' must instead make a 'dealing' disclosure as described below.

Under the provisions of Rule 8.3(b) of the Irish Takeover Rules, if any person is, or becomes, 'interested' in 1% or more of any class of 'relevant securities' of the Company, that person must publicly disclose all 'dealings' in any 'relevant securities' of the Company during the 'offer period', by not later than 3:30 p.m. (E.T.) on the 'business day' following the date of the relevant transaction.

If two or more persons co-operate on the basis of any agreement either express or tacit, either oral or written, to acquire an 'interest' in 'relevant securities' of the Company or any securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3 of the Irish Takeover Rules.

In addition, each of the Company and any offeror must make an 'opening position disclosure' by no later 12:00 noon (E.T.) on the date falling ten 'business days' following the commencement of the 'offer period' or the announcement that first identifies a securities exchange offeror, as applicable, and disclose details of any 'dealings' by it or any person 'acting in concert' with it in 'relevant securities' during the 'offer period', by no later than 12:00 noon (E.T.) on the business day following the date of the transaction (see Rules 8.1, 8.2 and 8.4).

A disclosure table, giving details of the companies in whose 'relevant securities' 'opening position' and 'dealings' should be disclosed can be found on the Irish Takeover Panel's website at www.irishtakeoverpanel.ie .

'Interests' in securities arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an 'interest' by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the Irish Takeover Rules, which can be found on the Irish Takeover Panel's website. If you are in any doubt as to whether or not you are required to disclose an 'opening position' or 'dealing' under Rule 8, please consult the Irish Takeover Panel's website at www.irishtakeoverpanel.ie or contact the Irish Takeover Panel on telephone number +353 1 678 9020.

It is agreed that the Acquisition will be implemented by way of an Irish High Court-sanctioned scheme of arrangement under Chapter 1 of Part 9 of the Irish Companies Act (although Amgen reserves the right to effect the Acquisition by way of a Takeover Offer, subject to the terms of the Transaction Agreement, compliance with the Irish Takeover Rules and with the consent of the Irish Takeover Panel).

Under the terms of the Acquisition, which will be subject to the Conditions and other terms set out in this Announcement and to further terms to be set out in the Scheme Document, each Company Shareholder at the Scheme Record Time will be entitled to receive:

$116.50 for each Company Share in cash

The Acquisition represents:

• a premium of approximately 47.9% to the closing price of $78.76 per Company Share on November 29, 2022 (being the last closing price per Company Share prior to the Company's issuance of an announcement of a possible offer under Rule 2.4 of the Irish Takeover Rules); and
  
  
• a premium of approximately 19.7% to the closing price of $97.29 per Company Share on December 9, 2022 .

The Acquisition values the entire issued and to be issued ordinary share capital of the Company at approximately $27.8 billion on a fully diluted basis and implies an enterprise value of approximately $28.3 billion .

The sources and bases of information contained in this Announcement to calculate the implied value of the Acquisition are set out in Appendix 1 ( Sources and Bases of Information ).

3. Company Background to and Reasons for Recommending the Acquisition

The Company is a biotechnology company focused on the discovery, development and commercialisation of medicines that address critical needs for people impacted by rare, autoimmune and severe inflammatory diseases. The Company Board, together with the Company's senior management, and with the assistance of its financial and legal advisors, regularly reviews the Company's strategic and financial prospects on a standalone basis in light of developments in the Company's business, the sectors in which it operates and the economy and financial markets generally.

Following receipt of an unsolicited proposal from Sanofi to acquire the entire issued and to be issued ordinary share capital of the Company for cash (the " Unsolicited Proposal "), the Company Board, together with the Company's senior management, and with the assistance of its outside advisors, met to discuss the Unsolicited Proposal and determined that the offer price was insufficient to warrant any substantive discussions or allow access to any due diligence and rejected the proposal. During the next 28 days, Sanofi made two subsequent proposals at higher prices before the Company Board determined that the proposed price was sufficient to permit Sanofi to receive a management presentation and access to limited additional information in order to support Sanofi making a further enhanced offer. The Company Board also determined that the best way to maximise shareholder value would be to approach other potential bidders and authorised the Company's senior management and its financial advisors to contact three additional global biopharmaceutical companies that it believed may be interested in a potential acquisition of the Company and would have the financial means to complete an acquisition of this size, with the outreach subject to obtaining the relevant consents of the Irish Takeover Panel. After obtaining the consents, the Company's financial advisors contacted the three parties, comprised of Amgen and two other global pharmaceutical companies (one such company being referred to herein as Company A and the other being Janssen Global Services, LLC (" JNJ ")), and conveyed that the Company had received an unsolicited proposal to be acquired on an expeditious timetable. All three parties expressed an interest in receiving a management presentation and engaging in due diligence to determine whether they would submit a proposal. The Company entered into confidentiality agreements with all four parties and gave each of the parties management presentations in a two day period and responded to preliminary due diligence questions. Subsequently, Amgen submitted an initial bid and Sanofi increased its proposed price. Company A declined to submit a proposal. JNJ indicated that it would continue to evaluate the information shared in the management presentation and would make a determination after a board meeting as to whether to submit a bid.

On November 29, 2022 , the Company released an announcement of a possible offer under Rule 2.4 of the Irish Takeover Rules, confirming that it was in highly preliminary discussions with Amgen, Sanofi and JNJ. On December 2, 2022 , Sanofi and Amgen each released a statement as required by Rule 2.12 of the Irish Takeover Rules confirming that any offer, if made, would be in cash. Subsequently, JNJ conveyed to the Company's financial advisors that it had decided not to submit a proposal and issued a statement on December 3, 2022 under Rule 2.8 of the Irish Takeover Rules that it did not intend to make an offer for the Company.

After considering the initial proposal from Amgen and the revised proposal from Sanofi, the Company Board authorised the Company to provide both parties with access to a due diligence data room and to provide both parties with a draft transaction agreement. After Amgen and Sanofi submitted proposed changes to the draft transaction agreement and identified required regulatory approvals, the Company Board authorised its financial advisors to send a process letter to both parties indicating that final offers with confirmation of funds certain should be submitted with a negotiated transaction agreement by no later than December 9, 2022 . At the instruction of the Company and its financial advisors, each of Amgen and Sanofi submitted its revised offer to acquire the Company on December 9, 2022 . On December 10, 2022 , the Company continued to discuss the offers from Sanofi and Amgen and received additional offers from Amgen and Sanofi at higher prices. Following the discussions with Amgen and Sanofi, the Company Board met on December 10, 2022 , together with the Company's senior management and financial and legal advisors, to consider proposed terms of the best and final proposals from each of Amgen and Sanofi. The Company Board, together with the Company's senior management, and with the assistance of its financial and legal advisors, reviewed the key legal and financial terms of each of the proposals from each of Amgen and Sanofi. Following discussions, the Company Board determined that the final proposal from Amgen was superior to the proposal from Sanofi and the near final drafts of the transaction agreements submitted by each party were substantially comparable. Following discussions, the Company Board unanimously determined to accept the terms of the offer received from Amgen of $116.50 per Company Share, resolving that such offer was in the best interests of the Company and the Company Shareholders, and thereby approved the Acquisition and resolved to recommend to the Company Shareholders that they approve the Acquisition.

The Company Board carefully considered the terms of the Acquisition and the other Transactions, consulted with Company senior management and its financial and legal advisors, and considered a number of factors, each of which is supportive of its unanimous decision to approve the Acquisition and the other Transactions and recommend the Transactions to the Company Shareholders.

The Company believes Amgen has the capacity to maximise the value of the Company's current portfolio and accelerate the ability for Horizon's medicines to reach more patients globally with increased global commercial scale as well as enhanced R&D and technology capabilities to rapidly advance the pipeline to find more therapies for patients who are underserved.

Further detail in respect of the background and reasons for recommending the Acquisition will be included in the Proxy Statement (which will include the Scheme Document).

4. Amgen Background to and Reasons for the Acquisition

Amgen believes there is a compelling strategic and financial rationale for undertaking the acquisition, which is expected to deliver the following benefits:

The Acquisition adds first-in-class / best-in-class innovative medicines that fit well with Amgen's portfolio and strategic vision

• Since its founding in 2005, the Company has successfully built a robust business with continued growth potential. TEPEZZA, KRYSTEXXA and UPLIZNA are innovative biologic medicines with impressive benefits that are reaching a growing number of patients suffering from serious diseases. These three early life cycle products collectively generated $2.0 billion of sales through the first nine months of 2022.
  
  
• Amgen's long-term strategy includes a focus on first-in-class and best-in-class innovative therapeutics that treat grievous illness, and on delivering those medicines to more patients around the world.
  
  
• The Company's focus and products align well with Amgen's long-term growth strategy:
• Amgen's growth reflects contributions from therapies with large addressable patient populations (such as cardiovascular disease, osteoporosis, psoriasis, and asthma), as well as therapies that address diseases with lower prevalence (such as ANCA- associated vasculitis, immune thrombocytopenic purpura and acute lymphoblastic leukemia) that are adjacent to Amgen's core therapeutic areas. TEPEZZA and KRYSTEXXA are a strong fit with the latter category and help to further diversify the Combined Group's revenue outlook.
  
  
• TEPEZZA has significant growth potential in key ex-U.S. markets such as Europe and Japan , which complements Amgen's international growth strategy.
  
  
• The Company's R&D efforts include significant lifecycle management expansion for currently marketed products, along with an innovative mid- to late-stage pipeline with opportunities for advancement of novel programs in disease areas such as myasthenia gravis, IgG4-related disease, systemic lupus erythematosus, lupus nephritis and Sjogren's Syndrome.

Amgen's global scale and 20-year history in commercializing inflammation therapies can accelerate growth of the Company's portfolio

• TEPEZZA is mechanistically rooted in inflammation and KRYSTEXXA is commercially aligned with Enbrel and TAVNEOS, given the shared rheumatology prescriber base. UPLIZNA targets an autoimmune disorder (neuromyelitis optica spectrum disorder), which is also consistent with Amgen's expertise in inflammation.
  
  
• The Company also has recent product approvals in Europe and Japan , where Amgen has existing commercial platforms that could be quickly leveraged and augmented with specialised sales force where needed. Globally, including the U.S., the Combined Group will benefit from Amgen's experience in commercial operations such as access, medical, patient support, and overall scale/expertise in marketing and sales.

The Company's platform strategies in R&D and manufacturing can be strengthened by Amgen's 40-year history in biologics, development and manufacturing

• Amgen has the scale, expertise, and resources to advance the Company's pipeline molecules with speed, and to support global registration and commercialisation. Given the Company's focus on biologics, Amgen also has the process development expertise to assist the Company in delivering lifecycle management programs focused on new formulations and new routes of administration. Amgen is also an industry leader in biologics manufacturing, which provides opportunities for manufacturing cost efficiencies while helping to ensure the Combined Group's products will reach "every patient, every time". Further, Amgen has considerable expertise in drug delivery systems that benefit the patient experience.

Strong financial profile with non-GAAP EPS accretion from 2024 and significant cash flow generation enabling continued attractive shareholder payouts and investment in innovation

• The robust free cash flow generated by the Combined Group (approximately $10 billion over the twelve months through Q3 2022) ¹ will enable de-levering following Completion, while continuing to support investment in the Combined Group's pipeline and commercial brands.
  
  
• The Acquisition is expected to be accretive to Amgen's revenue and non-GAAP earnings per share from 2024. Amgen is not providing or updating 2022 or 2030 guidance as a result of the Acquisition.
  
  
• Amgen's goal is to maintain a strong investment grade credit profile with debt leverage that is in-line with current levels by the end of 2025. Amgen expects to support this goal with over $10 billion of debt retirement through that period.
  
  
• Amgen remains committed to growing its annual dividend over time.
• The Acquisition is expected to deliver annual pre-tax cost synergies of at least $500 million by the end of the third fiscal year following Completion.

5. Company Board Recommendation

The Company Board, which has been so advised as to the financial terms of the Acquisition by Morgan Stanley, which has rendered a fairness opinion, considers the terms of the Acquisition to be fair and reasonable. In providing its financial advice, Morgan Stanley has taken into account the commercial assessments of the Company Directors. Morgan Stanley is providing independent financial advice to the Company Board for the purposes of Rule 3 of the Irish Takeover Rules. The Company Board has unanimously determined that the Transaction Agreement and the Transactions, including the Scheme, are advisable for, fair to and in the best interests of, the Company Shareholders. Accordingly, the Company Board unanimously recommends that Company Shareholders vote in favour of the Scheme Resolutions and the Required EGM Resolutions or, if the Acquisition is implemented by a Takeover Offer, to accept or procure acceptance of such Takeover Offer.

6. The Scheme Process

It is agreed that the Acquisition will be implemented by means of an Irish High Court-sanctioned scheme of arrangement between the Company and Company Shareholders under Chapter 1 of Part 9 of the Irish Companies Act, pursuant to which Acquirer Sub will acquire the entire issued and to be issued ordinary share capital of the Company and each Company Shareholder will receive the Consideration.

The Company Shares will be acquired pursuant to the Acquisition fully paid, non-assessable and free from all liens, charges, equities, encumbrances, rights of pre-emption and any other third party rights of any nature whatsoever and together with all rights attaching thereto, including without limitation voting rights and the right to receive and retain in full all dividends and other distributions (if any) announced, declared, made or paid with a record date on or after the Scheme Record Time.

To become effective, the Scheme will require, among other things, the approval of:

¹ For the twelve months through Q3 2022, Amgen GAAP operating cash flow of $9.88 billion less Amgen capital expenditures of $883 million plus Horizon GAAP operating cash flow of $1.37 billion less Horizon capital expenditures of $56 million = ~$10 billion

• the Scheme Meeting Resolution by a majority in number of members of each class of Company Shareholders (including as may be directed by the Irish High Court pursuant to Section 450(5) of the Irish Companies Act) present and voting either in person or by proxy at the Scheme Meeting (or at any adjournment or postponement of such meeting) representing, at the Voting Record Time, at least 75% in value of Company Shares of that class held by such Company Shareholders present and voting either in person or by proxy at the Scheme Meeting; and
  
  
• the Required EGM Resolutions being duly passed by the Company Shareholders at the EGM (or any adjournment or postponement thereof).

The Scheme Document will include full details of the Scheme, together with notices of the Scheme Meeting and the EGM and the expected timetable, and will specify the action to be taken by Company Shareholders.

Following the passing of the approvals noted above being obtained and the satisfaction or (where applicable) waiver of the other conditions to the consummation of the Scheme, the sanction of the Irish High Court will also be required in order for the Scheme to become effective.

Assuming the above requirements are satisfied, and the other Conditions, as described in more detail in paragraph 7 ( The Conditions ) below, have been satisfied or waived (where applicable), the Scheme will become effective upon delivery to the Irish Registrar of Companies of a copy of the Court Order.

Upon the Scheme becoming effective, the Scheme will be binding on all Company Shareholders, irrespective of whether or not they attended or voted at the Scheme Meeting or the EGM and share certificates, if any, in respect of Company Shares will cease to be valid and entitlements to Company Shares held within DTC will be cancelled.

Any Company Shares issued before the Scheme Record Time will be subject to the terms of the Scheme. One of the EGM Resolutions to be proposed at the EGM will, amongst other matters, provide that the Company's memorandum and articles of association be amended to incorporate provisions requiring any Company Shares issued after the Scheme Record Time (other than to Amgen or its affiliates), for example, due to the crystallisation of Company Options or Company Share Awards, to either be subject to the terms of the Scheme or acquired by Amgen and / or its affiliates on the same terms as the Acquisition (other than terms as to timings and certain formalities). The inclusion of these provisions in the Company's memorandum and articles of association will prevent any person (other than Amgen or its affiliates) holding Company Shares immediately after the Effective Time.

Subject to satisfaction or waiver (as applicable) of the Conditions, the Acquisition is expected to be completed in the first half of 2023.

If the Scheme does not become effective on or before the End Date (as may be extended pursuant to the Transaction Agreement), it will lapse and the Acquisition will not proceed (unless the Company, Amgen and Acquirer Sub otherwise agree and the Irish Takeover Panel otherwise consents).

7. The Conditions

As well as being conditional upon the Company Shareholder Approval and the Scheme becoming effective, as described in paragraph 5 ( The Scheme Process ) above, the Acquisition is also subject to receipt of certain other conditions as summarised below.

The Acquisition is subject to the satisfaction or waiver (as applicable) of the Conditions, which are set- out in full in Appendix 3 ( Conditions of the Acquisition and the Scheme ) to this Announcement, including, in summary:

• the approval by the Company Shareholders of the Scheme;
  
  
• the sanction of the Scheme by the Irish High Court;
  
  
• the receipt of required antitrust clearances in the United States , Austria and Germany and the receipt of required foreign investment clearances in France , Germany , Denmark and Italy ;
  
  
• a copy of the Court Order having been delivered to the Irish Registrar of Companies;
  
  
• the Transaction Agreement not having been terminated in accordance with its terms;
  
  
• the accuracy of each of the Parties' representations and warranties, subject to certain materiality and material adverse effect exceptions;
  
  
• the performance by each Party, in all material respects, with all of such Party's covenants and agreements under the Transaction Agreement; and
  
  
• the absence of a Company Material Adverse Effect that is continuing.

It is expected that the Proxy Statement (which will contain the Scheme Document), containing further information relating to the implementation of the Acquisition, the full terms and conditions of the Scheme, notices of the Scheme Meeting and the EGM, will be made available to Company Shareholders as promptly as reasonably practicable after securing approval of the Irish High Court to send the Scheme Document to Company Shareholders and, for information only, to Company Equity Award Holders.

The Proxy Statement will contain important information about the Acquisition (including the Scheme), the Transaction Agreement, the Scheme Meeting and the EGM.

10. Effect of the Scheme on Company Share Plans

In accordance with Rule 15 of the Irish Takeover Rules, Amgen will make appropriate proposals to participants of the Company Share Plans in relation to the options and awards under the Company Share Plans. Participants will be contacted separately, at or as soon as possible after the time of publication of the Scheme Document, regarding the effect of the Acquisition on their options and awards under the Company Share Plans and the relevant details will be summarised in the Scheme Document.

The Scheme will extend to any Company Shares which are unconditionally allotted or issued at or before the Scheme Record Time, including those allotted or issued to satisfy the exercise of options or vesting of awards under the Company Share Plans.

11. Management, Employees and Locations

As described in paragraph 4 ( Amgen Background to and Reasons for the Acquisition ) above, Amgen believes there is a compelling strategic rationale for undertaking the Acquisition, which would enable the Combined Group to deliver first-in-class medicines to many more patients suffering from serious illness. Amgen recognises the skills, knowledge and experience of the Company's employees and is excited to work with them to further enhance the therapeutic offerings, and grow the value, of the Combined Group in the longer term.

Following this Announcement, to the extent permitted by applicable antitrust rules, Amgen intends to engage with the Company's senior management in integration planning, involving a review of the Company's business. While the parameters of the review have not yet been finalised, Amgen expects that it will involve evaluating the best way in which to further develop, as part of the Combined Group following Completion, the three existing strategic goals of the Company, which are to (i) maximise the value of its on-market rare disease medicines through commercial execution and clinical investment; (ii) expand its R&D pipeline through significant internal investment and external business development; and (iii) build a global presence in targeted international markets.

In addition, the review will also involve assessing how best to combine the operations of Amgen and the Company in order to achieve some of the expected benefits of the Acquisition (including the cost synergies identified in paragraph 4 ( Amgen Background to and Reasons for the Acquisition ) above. The review would aim to identify and assess integration benefit opportunities, and to ascertain those areas in which a reduction in the number of employees of the Combined Group may be appropriate. Amgen has not yet carried out the review referred to above and, except as described below, has not reached any conclusions as to its likely outcome nor made any decisions in relation to specific actions that may be taken in relation to the integration of Amgen and the Company.

Amgen understands the importance of innovation to the Company's business, and intends to continue to invest in and develop its R&D capabilities as part of the Combined Group following Completion, with a view to ensuring in particular that the Company's existing pipeline of preclinical and clinical development programmes can continue to expand.

Management and employees

Amgen attributes significant value to the Company Group's management and employees, whose ongoing contribution will be key to growing the value of the enlarged business of Amgen in the longer term.

Amgen will safeguard the existing employment rights, including pension rights, of the Company Group's management and employees in accordance with applicable Law. Amgen does not envisage any material change in the conditions of employment of the management and employees of the Combined Group as a result of the Acquisition. Under the Transaction Agreement, Amgen has given certain assurances in relation to the continuation of certain existing compensation and employment benefit arrangements of the Company Group's employees following the Acquisition. Further details in this regard will be included in the Scheme Document.

While Amgen has not yet begun to carry out the review of the Company's business referred to above and has not reached any conclusions as to its likely outcome or made any decisions in relation to any specific actions that may be taken as a result of this evaluation in relation to employees of the Combined Group, Amgen currently anticipates that there will be some operational and administrative restructuring of the Company Group required following Completion. This will also facilitate the integration of the two businesses as part of the Combined Group. In particular, certain central corporate and support functions, including those relating to the Company's status as a listed company, may no longer be required on a standalone basis or may be reduced in scope. No decisions have been made as to the number of employees or the roles and locations that may be affected. Amgen also currently anticipates that there may be opportunities for the Combined Group to realise cost efficiencies from leveraging Amgen's global scale, systems and processes across various functions.

The non-executive directors of the Company intend to resign as directors of the Company with effect from Completion.

Headquarters, locations of business and fixed assets

Following Completion, the global headquarters of the Combined Group will be located at Amgen's current global headquarters in Thousand Oaks, California .

Amgen will, as part of its review of the Company's business referred to above, evaluate the consolidation of some or all of the Company's locations of business into Amgen's global headquarters in Thousand Oaks, California and other locations of Amgen across the United States and worldwide, including functions currently undertaken at the Company's current global headquarters in Dublin .

No material changes are envisaged by Amgen with respect to the redeployment of the Company's fixed asset base.

Trading facilities

The Company Shares are currently listed on the Nasdaq Global Select Market and, as set out in paragraph 12 ( Delisting of Company Shares ) below, the Company Shares will be delisted from the Nasdaq Global Select Market and deregistered, as promptly as practicable after the Effective Time, and in any event no more than ten days after the Completion Date.

12. Delisting of Company Shares

Prior to the Completion Date, the Company will cooperate with Amgen and use its reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable Laws and rules and policies of Nasdaq to enable the delisting of the Company Shares from Nasdaq and the deregistration of the Company Shares under the Exchange Act as promptly as practicable after the Effective Time. After the cancellation of the listing and trading of Company Shares on the Nasdaq Global Select Market, the Company will be re- registered as a private limited company.

13. Transaction Agreement

The Company, Amgen and Acquirer Sub have entered into the Transaction Agreement, dated December 11, 2022 , which contains certain assurances, obligations and commitments in relation to the implementation of the Acquisition, including provisions in relation to the conduct of the Company's business between the date of this Announcement and the Effective Date. A copy of the Transaction Agreement is appended to this Announcement at Appendix 4 ( Transaction Agreement ) and a summary of the principal terms of the Transaction Agreement will be set out in the Proxy Statement (which will include the Scheme Document).

The Transaction Agreement provides that neither the Company Directors nor the Company shall make a Company Change of Recommendation for a Company Superior Proposal or a Company Intervening Event or terminate the Transaction Agreement in order to substantially concurrently enter into a definitive agreement providing for a Company Superior Proposal, unless, among other things, prior to taking such action, the Company has notified Amgen in writing at least four Business Days before taking such action, that the Company intends to take such action, and has negotiated in good faith with Amgen regarding any proposal by Amgen to amend the Transaction Agreement.

The Transaction Agreement includes provisions pursuant to which the Company has agreed to reimburse to Amgen in certain circumstances set out below for an amount equal to all documented, specific, quantifiable third party costs and expenses incurred, directly or indirectly, by Amgen and / or any member of the Amgen Group, or on its behalf, for the purposes of, in preparation for, or in connection with the Acquisition, including third party costs and expenses incurred in connection with exploratory work carried out in contemplation of and in connection with the Acquisition, legal, financial and commercial due diligence, the arrangement of financing and the engagement of third party representatives to assist in the process (the " Expenses Reimbursement Provisions "). The gross amount payable by the Company to Amgen for such reimbursement shall not, in any event, exceed $278,404,301 (being 1% of the total value of the issued and to be issued ordinary share capital of the Company that is the subject of the Acquisition (excluding, for the avoidance of doubt, any interest in such share capital held by Amgen or any person Acting in Concert with Amgen)).

If the Transaction Agreement is terminated pursuant to its terms, Amgen's receipt of such reimbursement payment (to the extent owed by the Company pursuant to the Transaction Agreement) and Amgen's right to seek specific performance will be the sole and exclusive remedies of the Amgen Parties and the Amgen Related Parties against any of the Company and its Affiliates and Company Related Parties, including for any failure to consummate the Transactions or any claims or actions under applicable Laws arising out of any breach, termination or failure by the Company and its Affiliates to perform any covenant or agreement in the Transaction Agreement.

The amount payable by the Company to Amgen under the Expenses Reimbursement Provisions will exclude any amounts in respect of VAT incurred by Amgen or any member of the Amgen Group attributable to such third party costs other than irrevocable VAT incurred by Amgen or its Subsidiaries.

(ii) prior to the Scheme Meeting, a Company Alternative Proposal was publicly disclosed or announced and not withdrawn (or, in the case of a Company Breach Termination as a result of a material breach or failure to perform any covenant or agreement in the Transaction Agreement, was made publicly or privately to the Company Board), or any Person shall have publicly announced an intention (whether or not conditional) to make a Company Alternative Proposal that has not been withdrawn (it being understood that, for purposes of Section 9.2(b)(iii)(B) of the Transaction Agreement, references to " 20% " in the definition of Company Alternative Proposal shall be deemed to refer to " 50% "); and

(iii) (x) a Company Alternative Proposal is consummated within 12 months after such termination, or (y) a definitive agreement providing for a Company Alternative Proposal is entered into within 12 months after such termination and is subsequently consummated.

Morgan Stanley as Rule 3 Advisor to the Company and the Company have confirmed in writing to the Panel that, in the opinion of Morgan Stanley and the Company (respectively), in the context of the note to Rule 21.2 of the Irish Takeover Rules and the Acquisition, the Expenses Reimbursement Provisions are in the best interests of the Company Shareholders. The Irish Takeover Panel has consented to the Company entering into the Expenses Reimbursement Provisions.

The Transaction Agreement provides that, upon termination of the Transaction Agreement under certain circumstances relating to the failure to obtain applicable Antitrust Laws or Foreign Investment Laws Clearances prior to the End Date, Amgen will pay the Company a reverse termination fee of $974,415,054 .

14. Financing of the Acquisition

Amgen has entered into a Bridge Credit Agreement, dated December 12, 2022 , for an aggregate amount of $28.5 billion , by and among Amgen, Citibank N.A., as administrative agent, Bank of America, N.A., as syndication agent, and Citibank, N.A. and Bank of America, N.A. as lead arrangers and book runners, and the other banks from time to time party thereto to finance, together with Amgen's own cash resources, the Acquisition. Further information on the financing of the Acquisition will be set out in the Scheme Document.

PJT Partners, lead financial advisor to Amgen, is satisfied that sufficient resources are available to Acquirer Sub to satisfy in full the consideration payable to Company Shareholders under the terms of the Acquisition.

15. Other Acquisition-related Arrangements

The Company and Amgen entered into a confidentiality agreement on November 18, 2022 , pursuant to which the Company and Amgen have undertaken, amongst other things, to: (a) keep confidential information relating to the Acquisition and not to disclose it to third parties (other than certain permitted parties) unless required by Law or regulation; and (b) use the confidential information for the sole purpose of evaluating and participating in discussions regarding the Acquisition. The agreement also includes standstill provisions, pursuant to which Amgen has agreed to certain restrictions in respect of dealings in Company Shares, solicitation or engagement in respect of competing transactions, subject to customary standstill termination provisions, for a period of 12 months.

16. Tax

Each holder of Company Shares is urged to consult his, her or its independent professional advisor regarding the tax consequences of the Transactions.

17. Disclosure of Interests in Relevant Securities of the Company

As of the close of business on December 9, 2022 (being the last Business Day prior to the date of this Announcement), the Robert A. Eckert Living Trust (a related trust of Robert A. Eckert , an Amgen Director) was interested in 86 Company Shares.

Save as described above, as of the close of business on December 9, 2022 (being the last Business Day prior to the date of this Announcement), none of Amgen or, so far as Amgen is aware, any person Acting in Concert with Amgen:

Furthermore, no arrangement to which Rule 8.7 of the Irish Takeover Rules applies exists between Amgen or the Company or a person Acting in Concert with Amgen or the Company in relation to Company Shares. For these purposes, an "arrangement to which Rule 8.7 of the Irish Takeover Rules applies" includes any indemnity or option arrangement, and any agreement or understanding, formal or informal, of whatever nature, between two or more persons relating to relevant securities which is or may be an inducement to one or more of such persons to deal or refrain from dealing in such securities.

18. Section 3(7) of Appendix 4 Derogation

Section 3(7) of Appendix 4 of the Irish Takeover Rules requires that, except with the consent of the Panel, and subject to Rule 2.11 of the Irish Takeover Rules, the Company must send the Scheme Document to Company Shareholders within 28 days of the announcement of a firm intention to make an offer, being this Announcement.

On December 9, 2022 the Panel agreed to grant a waiver of Section 3 (7) of Appendix 4 of the Rules.

DISCLOSURE REQUIREMENTS OF THE IRISH TAKEOVER RULES

Under the provisions of Rule 8.3(a) of the Irish Takeover Rules, any person who is 'interested' in 1% or more of any class of 'relevant securities' of the Company must make an 'opening position disclosure' following the commencement of the 'offer period'. An 'opening position disclosure' must contain the details contained in Rule 8.6(a) of the Irish Takeover Rules, including, among other things, details of the person's 'interests' and 'short positions' in any 'relevant securities' of the Company. An 'opening position disclosure' by a person to whom Rule 8.3(a) applies must be made by no later than 3:30 pm (E.T.) on the day falling ten 'business days' following the commencement of the 'offer period'. Relevant persons who deal in any 'relevant securities' prior to the deadline for making an 'opening position disclosure' must instead make a 'dealing' disclosure as described below.

Under the provisions of Rule 8.3(b) of the Irish Takeover Rules, if any person is, or becomes, 'interested' in 1% or more of any class of 'relevant securities' of the Company, that person must publicly disclose all 'dealings' in any 'relevant securities' of the Company during the 'offer period', by not later than 3:30 p.m. (E.T.) on the 'business day' following the date of the relevant transaction.

If two or more persons co-operate on the basis of any agreement either express or tacit, either oral or written, to acquire an 'interest' in 'relevant securities' of the Company or any securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3 of the Irish Takeover Rules.

In addition, each of the Company and any offeror must make an 'opening position disclosure' by no later 12:00 noon (E.T.) on the date falling ten 'business days' following the commencement of the 'offer period' or the announcement that first identifies a securities exchange offeror, as applicable, and disclose details of any 'dealings' by it or any person 'acting in concert' with it in 'relevant securities' during the 'offer period', by no later than 12:00 noon (E.T.) on the business day following the date of the transaction (see Rules 8.1, 8.2 and 8.4).

A disclosure table, giving details of the companies in whose 'relevant securities' 'opening position' and 'dealings' should be disclosed can be found on the Irish Takeover Panel's website at www.irishtakeoverpanel.ie .

'Interests' in securities arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an 'interest' by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the Irish Takeover Rules, which can be found on the Irish Takeover Panel's website. If you are in any doubt as to whether or not you are required to disclose an 'opening position' or 'dealing' under Rule 8, please consult the Irish Takeover Panel's website at www.irishtakeoverpanel.ie or contact the Irish Takeover Panel on telephone number +353 1 678 9020.

3.6 Switching to a Takeover Offer.

(a) Subject to the terms of this Section 3.6 , in the event that Parent reasonably determines that a competitive situation (as that term is defined in the Irish Takeover Rules) exists or, based on facts known at the time, may reasonably be expected to arise in connection with the Acquisition, Parent may elect (subject to receiving the Irish Takeover Panel's consent, if required) to implement the Acquisition by way of the Takeover Offer (rather than the Scheme), whether or not the Scheme Document has been posted.

(f) For clarity and except as may be required by the Irish Takeover Rules (and without limiting any other provision of this Agreement), nothing in this Section 3.6 shall require the Company to provide Parent with any information with respect to, or to otherwise take or fail to take any action in connection with the Company's consideration of or response to, any actual or potential Company Alternative Proposal.

SECTION 4. EQUITY AWARDS

4.1 The Company Equity Awards.

(a) Company Options . Each Company Option that is outstanding as of immediately prior to the Effective Time (whether or not vested) shall, as of the Effective Time, by virtue of the occurrence of the Effective Time and without any further action on the part of the holder thereof, Parent, or the Company, be canceled and converted into the right to receive cash, without interest, in an amount equal to the product of (i) the total number of Company Shares subject to such Company Option immediately prior to the Effective Time, multiplied by (ii) the excess of (A) the Consideration over (B) the exercise price payable per Share under such Company Option, which amount shall be paid in accordance with Section 8.2 (the " Option Consideration "). No holder of a Company Option that has an exercise price per Share that is equal to or greater than the Consideration shall be entitled to any payment with respect to any such canceled Company Option before or after the Effective Time, and any such Company Option shall be canceled and shall cease to exist as of the Effective Time and no consideration shall be delivered in exchange therefor.

(b) Company Share Awards.

(i) Each Company RSU Award that is outstanding as of immediately prior to the Effective Time (whether or not vested) shall, by virtue of the occurrence of the Effective Time and without any further action on the part of the holder thereof, Parent, or the Company (A) if granted to a non-employee member of the Company Board or held by a person who, as of the Completion Date, is a former service-provider of the Company, be canceled and converted into the right to receive a cash, without interest, amount equal to (w) the total number of Company Shares subject to such Company RSU Award immediately prior to the Effective Time multiplied by (x) the Consideration, which amount shall be paid in accordance with Section 8.2 (the " RSU Cash Consideration ") and (B) if not granted to an individual described in clause (A) , be canceled and converted into a restricted stock unit (each, a " Parent RSU ") denominated in shares of common stock, $0.0001 par value, of Parent (" Parent Common Stock "). The number of shares of Parent Common Stock subject to each such Parent RSU shall be equal to the product (rounded down to the nearest whole number) of (y) the number of shares of Company Shares subject to such Company RSU Award immediately prior to the Effective Time multiplied by (z) the Equity Award Exchange Ratio. Except as specifically provided above, following the Effective Time, each such Parent RSU shall continue to be governed by the same terms and conditions (including vesting terms) as were applicable to the applicable Company RSU Award immediately prior to the Effective Time. For purposes of this Agreement, the term " Equity Award Exchange

Ratio " means (1) the Consideration divided by (2) the volume weighted average of the per share closing price of Parent Common Stock on the Nasdaq (as reported in the Eastern Edition of The Wall Street Journal or, if not reported thereby, another authoritative source) for five (5) trading days ending on the second Business Day prior to the Completion.

(ii) Each Company PSU Award that is outstanding as of immediately prior to the Effective Time (whether or not vested) shall by virtue of the occurrence of the Effective Time without any further action on the part of the holder thereof, Parent, or the Company be canceled and converted into the right to receive a cash amount, without interest, equal to (A) the total number of Company Shares issuable in settlement of such Company PSU Award as set forth below (" PSU Achievement ") multiplied by (B) the Consideration, which amount shall be paid in accordance with Section 8.2 (the " PSU Consideration "). PSU Achievement shall be determined in accordance with the terms of the applicable Company PSU Award, as determined by the Company Board or the compensation committee of the Company Board prior to the Effective Time, in consultation with, but not subject to the approval of, Parent.

4.2 Further Actions . Prior to the Effective Time, the Company Board (or, if appropriate, any committee thereof administering the Company Share Plans) shall take all actions, including by adopting any resolutions, obtaining any consents or approvals or otherwise, reasonably necessary to effectuate the transactions contemplated by this Section 4 .

4.3 Amendment of Articles . The Company shall procure that a special resolution be proposed to the Company Shareholders at the EGM proposing that the Company Memorandum and Articles of Association be amended so that any Company Shares allotted following Scheme Record Time will either be subject to the terms of the Scheme or acquired by Parent for the same consideration per Company Share as shall be payable to the Company Shareholders under the Scheme (depending upon the timing of such allotment); provided , however , that nothing in such amendment to the Company Memorandum and Articles of Association shall prohibit the sale (whether on a stock exchange or otherwise) of any Company Shares issued on the exercise of Company Options or vesting or settlement of Company Share Awards, as applicable, following the EGM but prior to the Scheme Record Time approved by the Irish High Court, it being always acknowledged that each and every Company Share will be bound by the terms of the Scheme.

(g) In the event that the latest date on which the Irish High Court or the Irish Takeover Panel would permit Completion to occur is prior to the End Date, the Parties shall use their respective reasonable best efforts to obtain consent of the Irish High Court or the Irish Takeover Panel, as applicable, to an extension of such latest date (but not beyond the End Date). If (i) the Irish High Court or the Irish Takeover Panel require the lapsing of the Scheme prior to the End Date, or (ii) the Condition set out in paragraph 1 of the Conditions fails to be satisfied, the Parties shall (unless and until this Agreement is terminated pursuant to and in accordance with Section 9 ) take all reasonable actions required in order to re-initiate the Scheme process as promptly as practicable (it being understood that no such lapsing described in clause (i) or (ii) shall, in and of itself, result in a termination of, or otherwise affect any rights or obligations of any Party under, this Agreement).

All rights to indemnification and advancement conferred hereunder shall continue as to a Person who has ceased to be a director or officer of the Company or any of its Subsidiaries after the date of this Agreement and shall inure to the benefit of such Person's heirs, successors, executors and personal and legal representatives.

(b) For a period of not less than six years from the Effective Date, Parent shall cause the Organizational Documents of the Company and its Subsidiaries to contain provisions no less favorable with respect to indemnification, advancement of expenses and limitations on liability of directors and officers than are set out in the Organizational Documents of the Company and its Subsidiaries as of the date of this Agreement, which provisions shall not be amended, repealed or otherwise modified for a period of at least six years from the Effective Date in any manner that would adversely affect the rights thereunder of any D&O Indemnified Party, unless any modification or amendment is required by applicable Laws (but then only to the extent required by applicable Laws). At the Company's option and expense, prior to the Effective Time, the Company may purchase (and pay in full the aggregate premium for) a six-year prepaid "tail" insurance policy (which policy by its express terms shall survive the Acquisition) of at least the same coverage and amounts and containing terms and conditions that are no less favorable to the directors and officers of the Company and its Subsidiaries as the Company's and its Subsidiaries' existing directors' and officers' insurance policy or policies with a claims period of six years from the Effective Time for D&O Claims arising from facts, acts, events or omissions that occurred on or prior to the Effective Time; provided that the premium for such tail policy shall not exceed 300% of the annual amount currently paid by the Company and its Subsidiaries for such insurance (such amount being the " Maximum Premium "). If the Company fails to obtain such tail policy prior to the Effective Time, Parent shall obtain such a tail policy; provided , however , that the premium for such tail policy shall not be required to exceed the Maximum Premium; provided , further , that if such tail policy cannot be obtained or can be obtained only by paying a premium in excess of the Maximum Premium, Parent shall only be required to obtain as much coverage as can be obtained by paying a premium equal to the Maximum Premium. Parent and the Company shall cause any such policy (whether obtained by Parent or the Company) to be maintained in full force and effect, for its full term, and Parent shall, following the Effective Time, cause the Company to honor all its obligations thereunder.

(c) If Parent or the Company or any of their respective successors or assigns (i) consolidates with or merges with or into any other Person and shall not be the continuing or surviving company, partnership or other Person of such consolidation or merger or (ii) liquidates, dissolves or winds-up, or transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of Parent or the Company, as applicable, assume the obligations set out in this Section 7.3 .

(d) The provisions of this Section 7.3 are intended to be for the express benefit of, and shall be enforceable by, each D&O Indemnified Party (who are intended to be third party beneficiaries of this Section 7.3 ), his or her heirs and his or her personal Representatives, shall be binding on all successors and assigns of Parent, and following the Effective Time, the Company. The exculpation and indemnification provided for by this Section 7.3 shall not be deemed to be exclusive of any other rights to which a D&O Indemnified Party is entitled, pursuant to applicable Laws or Contract made available to Parent prior to the date of this Agreement.

7.4 Employment and Benefit Matters.

(a) From the date of Completion through the first anniversary of the Effective Time (or, if shorter, the period of employment of the relevant Continuing Employee) (the " Benefits Continuation Period "), Parent shall provide or shall cause Acquirer Sub to provide, to (i) each Continuing Employee a base salary or hourly rate that is no less favorable than the base salary or hourly rate provided to such Continuing Employee immediately prior to the Effective Time, (ii) each Continuing Employee target annual or quarterly cash bonus, incentive compensation (excluding any special, retention or one-time award opportunities) and commissions opportunities (as applicable) that are no less favorable than the target annual or quarterly cash bonus, incentive compensation (excluding any special, retention or one-time award opportunities) and commissions opportunities provided to such Continuing Employee immediately prior to the Effective Time, and (iii) to the Continuing Employees as a group, employee benefits that are, in the aggregate, no less favorable than the employee benefits provided to similarly-situated employees of Parent and its Subsidiaries; provided that for purposes of determining whether such employee benefits are no less favorable in the aggregate, any equity, defined benefit pension plan benefits, nonqualified deferred compensation, retiree health or welfare benefits, post-termination health or welfare benefits, and retention or change in control payments or awards shall not be taken into account.

(b) In addition, Acquirer Sub shall provide, and Parent shall cause Acquirer Sub to provide, to each Continuing Employee who experiences a termination of employment during the Benefits Continuation Period, severance, termination and similar benefits that are no less favorable than the severance, termination and similar benefits to which such Continuing Employee would have been entitled upon such a termination of employment under any Employee Plan that is a severance plan, policy, program, agreement or arrangement and set out on Section 7.4(b) of the Company Disclosure Schedule (collectively, the " Severance Arrangements ") and in which such Continuing Employee was eligible to participate as of immediately prior to the Effective Time. For purposes of determining compliance with this Section 7.4(b) , only the existing terms of the Severance Arrangements will be taken into account, and any modifications to the Severance Arrangements that are effective after the date of this Agreement but prior to the Effective Time (and are made without Parent's advance written consent) will be disregarded.

(c) For purposes of vesting, eligibility to participate and determining level of benefits under the employee benefit plans of Parent or any Affiliate providing benefits to any Continuing Employees following the Effective Time (the " New Plans "), each Continuing Employee shall be credited with his or her years of service with the Company Group and its predecessors before the Effective Time, to the same extent and for the same purpose as such Continuing Employee was entitled, before the Effective Time, to credit for such service under the corresponding Employee Plan in which the Continuing Employee participated or was eligible to participate immediately prior to the Effective Time, provided that the foregoing shall not apply with respect to (i) any defined benefit pension plan or any retiree or post-termination health or welfare benefits, (ii) any benefit plan that is frozen or for which participation is limited to a grandfathered population, (iii) any cash- or equity-based compensation arrangements, or (iv) to the extent that its application would result in a duplication of benefits or compensation with respect to the same period of service, and provided , further , that such service shall only be credited to the extent service with Parent is credited for similarly situated employees of the Parent Group under the New Plans. In addition, and without limiting the generality of the foregoing, (A) each Continuing Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan is replacing comparable coverage under an Employee Plan in which such Continuing Employee had already satisfied any such waiting period and participated immediately before the Effective Time (such plans, collectively, the " Old Plans "), and (B) for purposes of each New Plan providing medical, dental, pharmaceutical or vision benefits to any Continuing Employee, Parent shall use its reasonable best efforts to (1) cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such employee and his or her covered dependents, unless and to the extent the individual, immediately prior to entry in the New Plans, was subject to such conditions under the comparable Old Plans, and (2) to the extent not prohibited by the terms, or by any third party administrator, of any New Plan that is a fully insured medical, dental, pharmaceutical or vision benefit plan of Parent or any Affiliate, credit each Continuing Employee with all deductible payments, co-payments and other out-of-pocket expenses incurred by such Continuing Employee and his or her covered dependents under the medical, dental, pharmaceutical or vision benefit plans of the Company prior to the Completion during the plan year in which the Completion occurs for the purpose of determining the extent to which such Continuing Employee has satisfied the deductible, co-payments or maximum out-of-pocket requirements applicable to such Continuing Employee and his or her covered dependents for such plan year under any New Plan that is a medical, dental, pharmaceutical or vision benefit plan of Parent or its Affiliates, as if such amounts had been paid in accordance with such plan (to the extent such credit would have been given under comparable Old Plans prior to the Completion).

(d) Prior to the Effective Time, if requested by Parent in writing, the Company shall cause any United States Tax-qualified defined contribution plan (collectively, the " Company 401(k) Plan ") to be terminated effective immediately prior to the Effective Time. In the event that Parent requests that the Company 401(k) Plan be terminated, the Company shall provide Parent with evidence that such Plan has been terminated (the form and substance of which shall be subject to review and approval by Parent) not later than the day immediately preceding the Effective Time. Upon the distribution of the assets in the accounts under the Company 401(k) Plan to the participants, Parent shall permit the Continuing Employees who are then actively employed by Parent or its Subsidiaries to make rollover contributions of "eligible rollover distributions" (within the meaning of Section 401(a)(31) of the Code), in the form of cash, from the Company 401(k) Plan to the applicable tax-qualified defined contribution plans of Parent or its Subsidiaries.

(e) Except as permitted pursuant to Section 10.1, prior to making any broad- based communications (written or oral) to the directors, officers or employees of the Company or any of its Subsidiaries pertaining to compensation or benefit matters that are affected by the transactions contemplated by this Agreement, 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.

(f) Nothing contained in this Section 7.4 (whether express or implied) shall (i) create or confer any rights, remedies or claims upon any employee of the Company or any of its Affiliates or any right of employment or engagement or continued employment or engagement or any particular term or condition of employment or engagement for any Company Employee or any other Person, (ii) be considered or deemed to establish, amend, or modify any Employee Plan or any other benefit or compensation plan, program, policy, agreement, arrangement, or Contract, (iii) prohibit or limit the ability of Parent or any of its Affiliates to amend, modify or terminate any benefit or compensation plan, program, policy, agreement, arrangement, or contract at any time assumed, established, sponsored or maintained by any of them or (iv) confer any rights or benefits (including any third-party beneficiary rights) on any Person other than the Parties.

The Company shall terminate the Company ESPP in its entirety effective as of the Effective Time, contingent upon the Effective Time. Prior to the Effective Time, the Company shall take all actions (including, if appropriate, amending the terms of the Company ESPP) that are necessary to give effect to the transactions contemplated by this Section 7.5 .

In addition to the foregoing, the Parent may also obtain Alternative Financing at its sole discretion which replaces the Financing, so long as the Parent is able to give the representations set forth in Section 6.2(h) with respect to such Alternative Financing as at the date such Alternative Financing becomes effective (with references to "date hereof," the "Financing," "Financing Sources" and "Debt Agreement" (and other like terms) in that section deemed to have been replaced with references to the date such Alternative Financing, the commitments thereunder and the agreements with respect thereto becomes effective).

(c) To the extent requested in writing by the Company from time to time, the Parent Parties shall provide the Company with updates on a reasonably current basis on the status of the Financing.

(i) by Parent or the Company pursuant to an End Date Termination, if, on the date of such termination, each of the Conditions has been satisfied or, to the extent permitted by applicable Laws, waived, (other than (X) paragraphs 3.1, 3.2 or 3.3 of the Conditions (only as a result of an Order or injunction under (1) the HSR Act or (2) any other Antitrust Law or Foreign Investment Laws in any Required Non-U.S. Jurisdiction), or (Y) paragraphs 2.3 and 2.4 of the Conditions or (Z) any Condition that by its nature can only be satisfied on the Sanction Date or, in the alternative to (Y) and (Z) where the Acquisition is implemented by Takeover Offer, any other condition that by its nature can only be satisfied by no later than the latest date upon which the Takeover Offer may be declared unconditional in all respects);

(ii) by Parent or the Company pursuant to a Restraining Order Termination pursuant to or in connection with (1) the HSR Act or (2) any other Antitrust Law or Foreign Investment Laws in any Required Non-U.S. Jurisdiction; or

(iii) by the Company pursuant to a Parent Breach Termination with respect to Section 7.2 in connection with (1) the HSR Act or (2) any other Antitrust Law or Foreign Investment Laws in any Required Non-U.S. Jurisdiction.

(d) Single Payment Only . The Parties acknowledge and agree that in no event will Parent or the Company be required to pay, as applicable, the Reverse Termination Payment or the Reimbursement Payment on more than one occasion, whether or not the Reverse Termination Payment or the Reimbursement Payment may be payable pursuant to more than one provision of this Agreement at the same or at different times and upon the occurrence of different events.

(e) VAT .

(i) VAT on the Reimbursement Payment . Parent and the Company consider that any amounts payable under this Section 9 do not represent consideration for a taxable supply for VAT purposes and agree to use all reasonable efforts to secure that any Reimbursement Payment should not represent consideration for a taxable supply for VAT purposes (including not taking any contrary position in any Tax filing or return or in any correspondence with any Tax Authority). If and to the extent that any relevant Tax Authority determines that any Reimbursement Payment is consideration for a taxable supply and that the Company (or any member of a VAT Group of which the Company is a member) is liable to account to a Tax Authority for VAT in respect of such supply and such VAT is Irrecoverable VAT:

(A) the sum of the total amount payable by the Company by way of any Reimbursement Payment, together with any Irrecoverable VAT arising in respect of the supply for which the Reimbursement Payment is consideration (" Company Irrecoverable VAT "), shall not exceed the Cap and the total amount of the Reimbursement Payment shall be reduced to ensure such;

(B) to the extent that the Company has already paid amounts in respect of any Reimbursement Payment the sum of which, when combined with any Company Irrecoverable VAT, exceeds the Cap, Parent shall repay to Company, by way of a reduction in the amount of the Reimbursement Payment, an amount necessary to ensure that the sum of the total remaining Reimbursement Payment combined with any Company Irrecoverable VAT arising in connection with such does not exceed the Cap; and

(C) the Company shall (and shall procure that any applicable member of the Company Group shall) accommodate any reasonable action that Parent requests, in writing and without delay, to avoid, dispute, defend, resist, appeal or compromise any determination of a Tax Authority that any Reimbursement Payment is consideration for a taxable supply for VAT purposes and/or that Company or any member of a VAT Group of which the Company is a member is liable to account to the relevant Tax Authority for VAT in respect of such supply and/or that all or any part of such VAT is Irrecoverable VAT.

(ii) VAT on the Reverse Termination Payment . Parent and the Company consider that any amounts payable under this Section 9 do not represent consideration for a taxable supply for VAT purposes and agree to use all reasonable efforts to secure that any Reverse Termination Payment should not represent consideration for a taxable supply for VAT purposes (including not taking any contrary position in any Tax filing or return or in any correspondence with any Tax Authority). If and to the extent that any relevant Tax Authority determines that any Reverse Termination Payment is consideration for a taxable supply and that the Company or an entity designated by the Company (or any member of a VAT Group of which the Company or an entity designated by the Company is a member) is liable to account to a Tax Authority for VAT in respect of such supply, Parent shall pay, in addition to the Reverse Termination Payment, an amount equal to such VAT to the Company or an entity designated by the Company (or any member of a VAT Group of which the Company or an entity designated by the Company is a member) immediately upon receipt of a valid VAT invoice.

(f) Recovered VAT . If the Reimbursement Payment is reduced in accordance with Section 9.2(e)(i)(A) and / or (B) and the Company (or any member of a VAT Group of which the Company is a member) subsequently becomes entitled to recover all, or any part, of the Company Irrecoverable VAT amount as originally applied to the calculation in accordance with Section 9.2(e)(i)(A) and / or (B) whether by way of credit or refund from the relevant Tax Authority, the Company shall notify Parent without delay and the Reimbursement Payment shall be increased to reflect the correct amount of Company Irrecoverable VAT subject to a maximum of the original Reimbursement Payment. However, the increase of the Reimbursement Payment shall be subject to a maximum to ensure at all times that the sum of the total increased Reimbursement Payment combined with any remaining Company Irrecoverable VAT arising in connection with such does not exceed the Cap. Where there is an increase in the Reimbursement Payment in accordance with this Section 9.2(f) , as soon as practicable (and, in any event, within five (5) Business Days of recovering whether by way of credit or refund any such VAT from the relevant Tax Authority), the Company (or the relevant member of a VAT Group of which the Company is a member) shall pay to Parent the appropriate amount by way of an increase in the Reimbursement Payment.

(g) Outside the European Union . Parent confirms that it is established outside of the European Union for VAT purposes and is a taxable person for VAT purposes within the meaning of applicable VAT Laws.

(h) Sole and Exclusive Remedy.

(i) If this Agreement is terminated pursuant to Section 9.1 , Parent's receipt of the Reimbursement Payment and any other amount to the extent owed pursuant to Section 9.2 and Parent's right to seek specific performance pursuant to Section 10.7 will be the sole and exclusive remedies of (x) Parent and Acquirer Sub and (y) the former, current and future holders of any equity, controlling persons, directors, officers, employees, agents, attorneys, Affiliates (other than Parent or Acquirer Sub), members, managers, general or limited partners, stockholders and assignees of each of Parent and Acquirer Sub (the Persons in clauses (x) and (y) collectively, the " Parent Related Parties ") against any of (A) the Company and its Affiliates; and (B) the former, current and future holders of any equity, controlling persons, directors, officers, employees, agents, attorneys, Affiliates, members, managers, general or limited partners, stockholders and assignees of each of the Company and its Affiliates (the Persons in clauses (A) and (B) collectively, the " Company Related Parties ") in respect of this Agreement, the Transactions, any agreement executed in connection herewith and the transactions contemplated hereby and thereby, the termination of this Agreement, the failure to consummate the Transactions or any claims or actions under applicable Laws arising out of any breach, termination or failure. Parent's receipt (or the receipt by such other Person as Parent may designate) of the Reimbursement Payment and any other amount to the extent owed pursuant to Section 9.2 will be the only monetary damages the Parent Related Parties may recover from Company Related Parties in respect of this Agreement, any agreement executed in connection herewith and the transactions contemplated hereby and thereby, the termination of this Agreement, the failure to consummate the Transactions or any claims or actions under applicable Laws arising out of any such breach, termination or failure, and upon payment of such amount, (A) none of the Company Related Parties will have any further liability or obligation to any of the Parent Related Parties relating to or arising out of this Agreement, any agreement executed in connection herewith or the transactions contemplated hereby and thereby or any matters forming the basis of such termination (except that the Parties (or their respective Affiliates) will remain obligated with respect to, and Parent may be entitled to remedies with respect to, the Confidentiality Agreement and Section 9.1(c), as applicable); and (B) none of Parent, Acquirer Sub or any other Person will be entitled to bring or maintain any Law against any Company Related Party arising out of this Agreement, the Transactions, any agreement executed in connection herewith or the transactions contemplated hereby and thereby or any matters forming the basis for such termination. Notwithstanding the foregoing, this Section 9.2(h)(i) will not relieve the Company from liability (I) for any Willful Breach of this Agreement or (II) for any breaches of the Confidentiality Agreement.

(ii) If this Agreement is terminated pursuant to Section 9.1, the Company's receipt of the Reverse Termination Payment and any other amount to the extent owed pursuant to Section 9.2 and the Company's right to seek specific performance pursuant to Section 10.7 will be the sole and exclusive remedies of the Company Related Parties against any of Parent Related Parties in respect of this Agreement, the Transactions, any agreement executed in connection herewith and the transactions contemplated hereby and thereby, the termination of this Agreement, the failure to consummate the Transactions or any claims or actions under applicable Laws arising out of any breach, termination or failure. The Company's receipt (or the receipt by such other Person as the Company may designate) of the Reverse Termination Payment and any other amount to the extent owed pursuant to Section 9.2 will be the only monetary damages the Company Related Parties may recover from Parent Related Parties in respect of this Agreement, any agreement executed in connection herewith and the transactions contemplated hereby and thereby, the termination of this Agreement, the failure to consummate the Transactions or any claims or actions under applicable Laws arising out of any such breach, termination or failure, and upon payment of such amount, (A) none of the Parent Related Parties will have any further liability or obligation to any of the Company Related Parties relating to or arising out of this Agreement, any agreement executed in connection herewith or the transactions contemplated hereby and thereby or any matters forming the basis of such termination (except that the Parties (or their respective Affiliates) will remain obligated with respect to, and the Company may be entitled to remedies with respect to, the Confidentiality Agreement and Section 9.1(c), as applicable); and (B) none of the Company or any other Person will be entitled to bring or maintain any Law against any Parent Related Party arising out of this Agreement, the Transactions, any agreement executed in connection herewith or the transactions contemplated hereby and thereby or any matters forming the basis for such termination. Notwithstanding the foregoing, this Section 9.2 will not relieve Parent from liability (I) for any Willful Breach of this Agreement or (II) for any breaches of the Confidentiality Agreement.

(iii) Each of the Parties acknowledges that any amount payable by the Company pursuant to this Section 9.2 , including the Reimbursement Payment, does not constitute a penalty, but rather shall constitute liquidated damages in a reasonable amount that will compensate Parent Parties for the disposition of its rights under this Agreement in the circumstances in which such amounts are due and payable, which amounts would otherwise be impossible to calculate with precision.

(iv) Each of the Parties acknowledges that any amount payable by Parent pursuant to this Section 9.2 , including the Reverse Termination Payment, does not constitute a penalty, but rather shall constitute liquidated damages in a reasonable amount that will compensate the Company and the entities designated by the Company for the operational impact of entering this Agreement and all related consequences on ongoing business activities in the event of a Specified Termination, which amounts would otherwise be impossible to calculate with precision.

(v) Any amount payable to the Company or its designee, or to Parent or its designee, as applicable, pursuant to this Section 9.2 shall be paid in such amounts and to such Persons as the Company or Parent, as applicable, shall designate within seven Business Days of the Specified Termination.

10.7 Inadequacy of Damages . The Parties acknowledge and agree that irreparable harm would occur and that the Parties would not have any adequate remedy at Law (i) for any breach of any of the provisions of this Agreement or (ii) in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms. It is accordingly agreed that, except where this Agreement is terminated in accordance with Section 9.1 , the Parties shall be entitled to seek an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to specifically enforce the terms and provisions of this Agreement, without proof of actual damages, and each Party further agrees to waive any requirement for the securing or posting of any bond in connection with such remedy. Subject to Section 9.1(b), the Parties further agree that (x) by seeking the remedies provided for in this Section 10.7 , a Party shall not in any respect waive its right to seek any other form of relief that may be available to a Party under this Agreement and (y) nothing contained in this Section 10.7 shall require any Party to institute any proceeding for (or limit any Party's right to institute any proceeding for) specific performance under this Section 10.7 before exercising any termination right under Section 9.1 (and pursuing damages after such termination), nor shall the commencement of any action pursuant to this Section 10.7 or anything contained in this Section 10.7 restrict or limit any Party's right to terminate this Agreement in accordance with the terms of Section 9.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

10.8 Disclosure Schedule References and SEC Document References.

(a) The Parties agree that each section or subsection of the Company Disclosure Schedule, shall be deemed to qualify the corresponding section or subsection of this Agreement, irrespective of whether or not any particular section or subsection of this Agreement specifically refers to the Company Disclosure Schedule. The Parties further agree that disclosure of any item, matter or event in any particular section or subsection of either the Company Disclosure Schedule shall be deemed disclosure with respect to any other section or subsection of the Company Disclosure Schedule, to which the relevance of such disclosure would be reasonably apparent on its face, notwithstanding the omission of a cross-reference to such other section or subsections.

(b) The Parties agree that in no event shall any cautionary, predictive or forward-looking statements contained in any part of any Company SEC Document entitled "Risk Factors," "Forward-Looking Statements," "Cautionary Statement Regarding Forward-Looking Statements," "Special Note Regarding Forward Looking Statements" or "Note Regarding Forward Looking Statements" be deemed to be an exception to (or a disclosure for purposes of or otherwise qualify) any representations and warranties of any Party contained in this Agreement.

(c) Remedies and Waivers . No delay or omission by either Party in exercising any right, power or remedy provided by Law or under this Agreement shall affect that right, power or remedy or operate as a waiver of it. The exercise or partial exercise of any right, power or remedy provided by Law or under this Agreement shall not preclude any other or further exercise of it or the exercise of any other right, power or remedy.

10.9 Severability.

(a) If any term, provision, covenant or condition of this Agreement or the Acquisition is held by a court of competent jurisdiction or other Governmental Entity to be invalid, void or unenforceable, the Parties shall negotiate in good faith to modify this Agreement or, as appropriate, the terms and conditions of this Agreement and the Acquisition, so as to effect the original intent of the Parties as closely as possible in an equitable manner in order that the Transactions may be consummated as originally contemplated to the fullest extent possible in accordance with applicable Laws.

(b) If at any time any provision of this Agreement is or becomes illegal, invalid or unenforceable in any respect under the Law of any jurisdiction, that shall not affect or impair (i) the legality, validity or enforceability in that jurisdiction of any other provision of this Agreement; or (ii) the legality, validity or enforceability under the Law of any other jurisdiction of that or any other provision of this Agreement.
