AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER (this “Agreement”), dated as of May 29, 2017, is by and among Ensco plc, a public limited company organized under the Laws of England and Wales (“Parent”), Echo Merger Sub LLC, a Texas limited liability company and wholly owned subsidiary of Parent (“Merger Sub”), and Atwood Oceanics, Inc., a Texas corporation (the “Company” and, together with Parent and Merger Sub, the “Parties”).

WITNESSETH:

WHEREAS, upon the terms and subject to the conditions of this Agreement and in accordance with the Texas Business Organizations Code (“TBOC”), the Parties intend that Merger Sub will merge with and into the Company (the “Merger”), with the Company continuing as the surviving corporation in the Merger and a wholly owned subsidiary of Parent (sometimes referred to in such capacity as the “Surviving Company”);

WHEREAS, the Board of Directors of the Company (the “Company Board”) has (i) unanimously determined that it is in the best interests of the Company and the Company Shareholders to enter into this Agreement and the transactions contemplated hereby, including the Merger, (ii) approved the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby, including the Merger, and (iii) resolved to submit this Agreement to a vote of the Company Shareholders and recommend approval of this Agreement by the Company Shareholders;

WHEREAS, the Board of Directors of Parent (the “Parent Board”) has (i) unanimously determined that it is in the best interests of Parent and the Parent Shareholders to enter into, and has declared advisable, this Agreement and the transactions contemplated hereby, including the Merger, (ii) approved the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby, including the Merger, and (iii) resolved to recommend the passing of the Parent Shareholder Resolutions by the Parent Shareholders;

WHEREAS, Parent, as the sole member of Merger Sub, has approved the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby, including the Merger, and approved this Agreement; and

WHEREAS, Parent, Merger Sub and the Company desire to make certain representations, warranties, covenants and agreements specified herein in connection with this Agreement.

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

ARTICLE I.

THE MERGER

Section 1.1 The Merger. At the Effective Time, upon the terms and subject to the conditions set forth in this Agreement and in accordance with the applicable provisions of the TBOC, Merger Sub shall be merged with and into the Company, whereupon the separate existence of Merger Sub shall cease, and the Company shall continue its existence under Texas Law as the Surviving Company in the Merger and a wholly owned subsidiary of Parent.

Section 1.2 Closing. The closing of the Merger (the “Closing”) shall take place at the offices of Latham & Watkins LLP, 811 Main Street, 37th Floor, Houston, Texas as soon as practicable (and in any event within five business days) after the satisfaction or waiver (to the extent permitted by applicable Law) of the conditions set forth in Article VI (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions), or at such other place, date and time as the Company and Parent may agree in writing. The date on which the Closing actually occurs is referred to as the “Closing Date.”

Section 1.3 Effective Time. On the Closing Date, the Company and Merger Sub shall file with the Secretary of State of the State of Texas a certificate of merger (the “Certificate of Merger”), executed in accordance with, and containing such information as is required by, the relevant provisions of the TBOC in order to effect the Merger. The Merger shall become effective at such time as the Certificate of Merger has been filed with the Secretary of State of the State of Texas or at such other, later date and time as is agreed between the Parties and specified in the Certificate of Merger in accordance with the relevant provisions of the TBOC (such date and time is hereinafter referred to as the “Effective Time”).

Section 1.4 Effects of the Merger. The effects of the Merger shall be as provided in this Agreement and in the applicable provisions of the TBOC. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all of the property, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Company, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Company, all as provided under the TBOC.

Section 1.5 Organizational Documents of the Surviving Company. At the Effective Time, the Company Charter and Company Bylaws as in effect immediately prior to the Effective Time will remain unchanged and will be the articles of incorporation and bylaws of the Surviving Company until duly amended in accordance with the terms thereof and applicable Law.

Section 1.6 Directors and Officers. Subject to applicable Law, the officers of Merger Sub immediately prior to the Effective Time shall be the initial directors and officers of the Surviving Company and shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal.

Section 1.7 Parent Board.

(a) Parent shall take such actions as are necessary for the Parent Board to expand the size of the Parent Board and to appoint two persons designated by the Company (the “Alpha Director Nominees”) to fill such vacancies, effective as of the Effective Time, to serve until such person’s successor is elected by the Parent Shareholders or until such person’s death, retirement, resignation or removal by the Parent Shareholders. Each designee shall be a current non-employee director of the Company as agreed between Parent and the Company and shall qualify as an independent director of Parent under the listing rules of the NYSE.

(b) Except as provided in Article II, the Parties shall ensure that the remuneration (including any share or stock awards) to be paid to the Alpha Director Nominees after the Effective Time shall be compatible with Parent’s directors’ remuneration policy.

ARTICLE II.

CONVERSION OF SHARES; EXCHANGE OF CERTIFICATES

Section 2.1 Effect on Capital Stock.

(a) At the Effective Time, by virtue of the Merger and without any action on the part of Parent, the Company, Merger Sub or the holder of any shares of Company Common Stock or limited liability company interests of Merger Sub:

(i) Limited Liability Company Interest of Merger Sub. The sole limited liability company interest of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and nonassessable share of common stock, par value $1.00 per share, of the Surviving Company and shall constitute the only outstanding shares of capital stock of the Surviving Company.

(ii) Cancellation of Certain Stock. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time that is owned or held in treasury by the Company and each share of Company Common Stock issued and outstanding immediately prior to the Effective Time that is owned by Parent or Merger Sub or any of their respective Subsidiaries shall no longer be outstanding and shall automatically be cancelled and shall cease to exist (the “Cancelled Shares”), and no consideration shall be delivered in exchange therefor.

(iii) Conversion of Company Common Stock. Subject to the other provisions of Article II, each share of Company Common Stock issued and outstanding immediately prior to or upon the Effective Time, excluding any Cancelled Shares (each, a “Company Share”), shall be converted automatically into and shall thereafter represent the right to receive 1.60 (the “Exchange Ratio”) Parent Class A Ordinary Shares (the “Merger Consideration”), credited as fully paid and free from all Liens.

All Company Shares converted into the right to receive the Merger Consideration pursuant to this Article II shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and uncertificated Company Shares represented by book-entry form

(“Book-Entry Shares”) and each certificate that, immediately prior to the Effective Time, represented any such Company Shares (each, a “Certificate”) shall thereafter represent only the right to receive the Merger Consideration and the Fractional Share Cash Amount into which the Company Shares represented by such Book-Entry Share or Certificate have been converted pursuant to this Section 2.1, as well as any amounts to which holders of Company Shares become entitled in accordance with Section 2.2(e).

(b) No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger and the other transactions contemplated hereby.

(c) Certain Adjustments. If, between the date of this Agreement and the Effective Time (and as permitted by Article V), the outstanding Company Shares or Parent Class A Ordinary Shares shall have been changed into, or exchanged for, a different number of shares or a different class of shares by reason of any stock dividend, subdivision, reorganization, reclassification, recapitalization, share split, reverse share split, combination or exchange of shares, or a stock dividend shall be declared with a record date within such period, or any similar event shall have occurred, then the Exchange Ratio shall be equitably adjusted, without duplication, to proportionally reflect such change; provided, that nothing in this Section 2.1(c) shall be construed to permit the Company or Parent to take any action with respect to its securities that is prohibited by Section 5.1 or the other terms of this Agreement.

(d) No Fractional Shares. No fractional Parent Class A Ordinary Shares shall be issued in connection with the Merger, no certificates or scrip representing fractional Parent Class A Ordinary Shares shall be delivered upon the conversion of Company Shares pursuant to Section 2.1(a)(iii), and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a holder of Parent Class A Ordinary Shares. Notwithstanding any other provision of this Agreement, each holder of Company Shares converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a Parent Class A Ordinary Share (after aggregating all shares represented by the Certificates and Book-Entry Shares delivered by such holder) shall receive, in lieu thereof and upon surrender thereof, cash (without interest) in an amount determined by multiplying (i) the Parent Closing Price by (ii) the fraction of a Parent Class A Ordinary Share (after taking into account all Company Shares held by such holder at the Effective Time and rounded to the nearest one thousandth when expressed in decimal form) to which such holder would otherwise be entitled (the “Fractional Share Cash Amount”). No such holder shall be entitled to dividends, voting rights or any other rights in respect of any fractional Parent Class A Ordinary Shares.

Section 2.2 Exchange of Certificates.

(a) Exchange Agent. Prior to the Closing Date, Parent shall appoint a bank or trust company that is reasonably acceptable to the Company to act as exchange agent (the “Exchange Agent”) for the payment of the Merger Consideration and shall enter into an agreement relating to the Exchange Agent’s responsibilities under this Agreement.

(b) Exchange Fund. As of the Effective Time, Parent shall (i) allot to each holder of record of Company Shares such whole number of Parent Class A Ordinary Shares as such holder is entitled to receive under Section 2.1(a)(iii), which allotment shall be conditional

only upon (and such Parent Class A Ordinary Shares shall be issuable upon) compliance with Section 2.2(d), and (ii) make available to the Exchange Agent cash sufficient to pay the aggregate Fractional Share Cash Amounts payable (such Parent Class A Ordinary Shares as are allotted to the holders of record of Company Shares, together with any dividends or distributions with respect thereto, and the cash sufficient to pay the aggregate Fractional Share Cash Amount, the “Exchange Fund”).

(c) Exchange Procedures. As soon as reasonably practicable after the Effective Time and in any event within five business days of the Closing Date, Parent shall cause the Exchange Agent to mail to each holder of record of Company Shares (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass (as applicable), only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent and the Company may reasonably agree upon prior to the Effective Time) (the “Letter of Transmittal”) and (ii) instructions for use in effecting the surrender of Certificates or Book-Entry Shares (as applicable) in exchange for the Merger Consideration, any Fractional Share Cash Amount and any amounts to which such Certificates or Book-Entry Shares become entitled in accordance with Section 2.2(e).

(d) Surrender of Certificates or Book-Entry Shares. Upon surrender of Certificates or Book-Entry Shares to the Exchange Agent, if applicable, together with a Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may customarily be required by the Exchange Agent, the holder of such Certificates or Book-Entry Shares shall be entitled to receive in exchange therefor the Merger Consideration deliverable in respect of the shares represented by such Certificates or Book-Entry Shares pursuant to this Agreement, together with any Fractional Share Cash Amount and amounts to which such Certificates or Book-Entry Shares become entitled in accordance with Section 2.2(e). In the event of a transfer of ownership of shares of Company Common Stock that is not registered in the transfer or stock records of the Company, any Parent Class A Ordinary Shares to be issued upon due surrender of the Certificate or Book-Entry Share formerly representing such shares of Company Common Stock may be issued to a transferee if such Certificate or Book-Entry Share is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer or other similar Taxes have been paid or are not applicable. Until surrendered as contemplated by this Section 2.2, each Certificate and Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive, upon such surrender, the Merger Consideration deliverable in respect of the shares represented by such Certificates or Book-Entry Shares pursuant to this Agreement, together with any Fractional Share Cash Amount and any amounts to which such Certificates or Book-Entry Shares become entitled in accordance with Section 2.2(e).

(e) Treatment of Unexchanged Shares. No dividends or other distributions, if any, with a record date after the Effective Time with respect to Parent Class A Ordinary Shares (or amounts in respect thereof), shall be paid to the holder of any unsurrendered Company Share to be converted into Parent Class A Ordinary Shares pursuant to Section 2.1(a)(iii) until such holder shall surrender such share in accordance with this Section 2.2. After the surrender in accordance with this Section 2.2 of a Company Share to be converted into Parent Class A Ordinary Shares pursuant to Section 2.1(a)(iii), the holder thereof shall be entitled to receive (in addition to the Merger Consideration and any Fractional Share Cash Amount) an amount equal to any such

dividends or other distributions, without any interest thereon, which had been paid upon a Parent Class A Ordinary Share prior to such time (or had been declared prior to such time but are unpaid at such time) multiplied by the number of Parent Class A Ordinary Shares being issued to such holder.

(f) No Further Ownership Rights in Company Common Stock. The Merger Consideration delivered in accordance with the terms of this Article II upon conversion of any Company Shares, together with the Fractional Share Cash Amount and any amounts to which such Company Shares become entitled in accordance with Section 2.2(e), shall be deemed to have been delivered and paid in full satisfaction of all rights pertaining to such Company Shares. From and after the Effective Time, (i) all holders of Certificates and Book-Entry Shares shall cease to have any rights as shareholders of the Company other than the right to receive the Merger Consideration into which the shares represented by such Certificates or Book-Entry Shares have been converted pursuant to this Agreement upon the surrender of such Certificate or Book-Entry Share in accordance with Section 2.2(d) (together with any Fractional Share Cash Amount and any amounts to which such Certificates or Book-Entry Shares become entitled in accordance with Section 2.2(e)), without interest, and (ii) the stock transfer books of the Company shall be closed with respect to all Company Shares outstanding immediately prior to the Effective Time and there shall be no further registration of transfers on the stock transfer books of the Surviving Company of Company Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificates or Book-Entry Shares formerly representing Company Shares are presented to the Surviving Company, Parent or the Exchange Agent for any reason, such Certificates or Book-Entry Shares shall be cancelled and exchanged as provided in this Article II.

(g) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent; provided, however, that no such investment or loss thereon shall affect the amounts payable to holders of Certificates or Book- Entry Shares pursuant to this Article II, and following any losses from any such investment, Parent shall promptly provide additional funds to the Exchange Agent for the benefit of the holders of shares of Company Common Stock at the Effective Time in the amount of such losses, which additional funds will be deemed to be part of the Exchange Fund. Any interest or other income resulting from such investments shall be paid to Parent, upon demand.

(h) Termination of Exchange Fund. Any portion of the Exchange Fund (including any interest or other amounts received with respect thereto) that remains unclaimed by, or otherwise undistributed to, the holders of Certificates and Book-Entry Shares for 180 days after the Effective Time shall be delivered to Parent, upon demand, and any holder of Certificates or Book-Entry Shares who has not theretofore complied with this Article II shall thereafter look only to Parent or the Surviving Company (subject to abandoned property, escheat or other similar Laws), as general creditors thereof, for satisfaction of its claim for Merger Consideration, the Fractional Share Cash Amount and any dividends and distributions which such holder has the right to receive pursuant to this Article II without any interest thereon.

(i) No Liability. None of Parent, the Company, Merger Sub or the Exchange Agent shall be liable to any person in respect of any portion of the Exchange Fund or the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Notwithstanding any other provision of this Agreement, any portion of the Merger

Consideration or any cash to be paid in accordance with this Article II that remains undistributed to the holders of Certificates and Book-Entry Shares as of the second anniversary of the Effective Time (or immediately prior to such earlier date on which the Merger Consideration or such cash would otherwise escheat to or become the property of any Governmental Entity), shall, to the extent permitted by applicable Law, become the property of the Parent, free and clear of all claims or interest of any person previously entitled thereto.

(j) Withholding Rights. Each of the Surviving Company, Parent, Merger Sub and the Exchange Agent, and their respective affiliates (without duplication), shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under applicable Law. To the extent that amounts are so withheld and paid over to the appropriate Tax authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Certificate or Book-Entry Share in respect of which such deduction and withholding was made.

(k) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent or the Exchange Agent, the posting by such person of a bond in such amount as Parent or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it or the Surviving Company with respect to such Certificate, the Exchange Agent (or, if subsequent to the termination of the Exchange Fund and subject to Section 2.2(h), Parent) shall deliver, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration and any dividends and distributions deliverable in respect thereof pursuant to this Agreement.

Section 2.3 Stock Awards.

(a) Company Restricted Stock Units. As of the Effective Time, each award of Company restricted stock units other than any Company restricted stock units that are required to be settled in cash (“Company RSUs”) that is outstanding as of immediately prior to the Effective Time, shall, in accordance with the terms of such awards, become fully vested as of the Effective Time, with such awards that are subject to performance-based vesting terms or conditions becoming earned and vested at the target level or such higher level as determined by the compensation committee of the Company Board in its sole discretion (but not to exceed 200% of the target level). As soon as practicable after the Effective Time, such Company RSUs will be settled through the issuance to the holders thereof of Parent Class A Ordinary Shares in an amount equal to the number of shares of Company Common Stock originally subject to such award of Company RSUs, multiplied by the Exchange Ratio (rounded down to the nearest whole share), and otherwise in accordance with the terms of such awards and subject to the holder’s obligations to satisfy any tax withholding obligations in connection with the settlement of such awards. Each award of Company restricted stock units that is required to be settled in cash shall be treated in accordance with the terms of such award.

(b) Company Stock Options. Each award of stock options that has been granted under the Company Stock Plans (each, an “Existing Option”) and that remains outstanding and unexercised immediately prior to the Effective Time, shall, as of the Effective Time, automatically

and without any further action being required, become fully vested and exercisable and converted into a stock option relating to Parent Class A Ordinary Shares, on the same terms and conditions (including expiration terms) as were applicable to such Existing Option immediately prior to the Effective Time (each, a “Converted Option”), except that (A) the number of Parent Class A Ordinary Shares subject to such Converted Option shall be determined by multiplying the number of shares of Company Common Stock subject to the corresponding Existing Option immediately prior to the Effective Time by the Exchange Ratio, and then rounded down to the nearest whole share, and (B) the exercise price per share of the Converted Option shall equal the per share exercise or strike price of the Existing Option immediately prior to the Effective Time divided by the Exchange Ratio, rounded up to the nearest whole cent.

(c) Company Actions. The Company shall take, or procure the taking of, all action necessary, as applicable, to provide for the treatment of the Company RSUs and Existing Options (collectively, the “Company Stock Awards”) as set forth in the foregoing provisions of this Section 2.3.

(d) Parent Actions. As of the Effective Time, Parent shall assume all of the Company Stock Plans, including (i) all of the obligations of the Company with respect to the Company Stock Awards and (ii) with respect to any amount of shares (as adjusted pursuant to the Exchange Ratio) that remain (or may again become) available for future issuance thereunder (“Remaining Stock Plan Shares”), subject to any limitations under applicable Law or any applicable securities exchange listing requirements. In addition, Parent shall promptly file with the SEC one or more appropriate registration statements with respect to all Converted Options held by individuals who are actively employed or in service with the Company as of the Effective Time and all Parent Class A Ordinary Shares that may be issued in connection with the Company RSUs and Remaining Stock Plan Shares.

Section 2.4 Further Assurances. If at any time before or after the Effective Time, Parent or the Company reasonably believes or is advised that any further instruments, deeds, assignments or assurances are reasonably necessary or desirable to consummate the Merger or to carry out the purposes and intent of this Agreement at or after the Effective Time, then Parent, Merger Sub and the Company and their respective officers and directors shall execute and deliver all such proper instruments, deeds, assignments or assurances and do all other things reasonably necessary or desirable to consummate the Merger and to carry out the intent and purposes of this Agreement.

ARTICLE III.

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except as disclosed (a) in the Company SEC Documents filed prior to the date hereof (without giving effect to any amendment to any such Company SEC Document filed on or after the date hereof and excluding any disclosures set forth in any such Company SEC Document in any risk factor section, any disclosure in any section relating to forward-looking statements or any other statements that are non-specific, predictive or primarily cautionary in nature other than historical facts included therein), where the relevance of the information as an exception to (or disclosure for purposes of) a particular representation is reasonably apparent on the face of such disclosure, or (b) in the disclosure schedule delivered by the Company to Parent immediately prior

to the execution of this Agreement (the “Company Disclosure Schedule”) (each section of which qualifies the correspondingly numbered representation, warranty or covenant if specified therein and such other representations, warranties or covenants where its relevance as an exception to (or disclosure for purposes of) such other representation, warranty or covenant is reasonably apparent), the Company represents and warrants to Parent as follows:

Section 3.1 Qualification, Organization, Subsidiaries, Capitalization.

(a) The Company is a corporation duly incorporated and validly existing under the Laws of the State of Texas. The Company has the requisite corporate power and authority to own, lease and operate its properties and assets and to carry on its business as presently conducted except for any such failures to have such power and authority as would not, individually or in the aggregate, have a Company Material Adverse Effect. Each of the Company’s Subsidiaries is a legal entity duly organized, validly existing and in good standing (where such concept is recognized under applicable Law) under the Laws of its jurisdiction of organization and has the requisite entity capacity, power and authority to own, lease and operate its properties and assets and to carry on its business as presently conducted, except where the failure to be in good standing or to have such power or authority would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect. Each of the Company and its Subsidiaries is duly qualified or licensed, and has all necessary governmental approvals, to do business and is in good standing as a foreign entity (where such concept is recognized under applicable Law) in each jurisdiction in which the property owned, leased or operated by it or the nature of the business conducted by it makes such approvals, qualification or licensing necessary, except where the failure to be so duly approved, qualified or licensed and in good standing would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect.

(b) The Company has made available to Parent, prior to the date hereof, true and complete copies of the Company Charter, Company Bylaws and the certificate of incorporation, certificate of limited partnership, certificate of formation, bylaws, limited partnership agreement, limited liability company agreement or comparable constituent or organizational documents for each of its material Subsidiaries as identified in Section 3.1(b) of the Company Disclosure Schedule (the “Company Material Subsidiaries”), in each case as amended to and in effect as of the date hereof (collectively, the “Company Organizational Documents”). The Company is not in violation, and none of the Company’s Subsidiaries is in material violation, of any of the Company Organizational Documents.

(c) The authorized capital stock of the Company consists of 180,000,000 shares of common stock, par value $1.00 per share (the “Company Common Stock”), and 1,000,000 shares of preferred stock, no par value (the “Company Preferred Stock”). As of the close of business on May 26, 2017 (i) 80,519,422 shares of Company Common Stock were issued and outstanding, (ii) no shares of Company Preferred Stock were issued and outstanding, (iii) no shares of Company Common Stock were held in treasury and (iv) up to 760,135 shares of Company Common Stock were available for issuance under the Company Stock Plans, of which amount (A) 647,656 shares of Company Common Stock may be issued upon the exercise of Existing Options, and (B) 2,988,083 shares of Company Common Stock were subject to awards of Company RSU Awards, with performance-based awards reflected in such number at the “target” level. The Company has made available to Parent a complete and correct list of the Company Stock Awards

the certifications required pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act. The Company’s management has completed an assessment of the effectiveness of the Company’s internal control over financial reporting in compliance with the requirements of Section 404 of the Sarbanes-Oxley Act for the year ended September 30, 2016, and such assessment concluded that such controls were effective.

Except to the extent

necessary to take any actions that the Company or any third party would otherwise be permitted to take pursuant to this Section 5.4 (and in such case only in accordance with the terms hereof), (A) the Company and its Subsidiaries shall not release any third party from, or waive, amend or modify any provision of, or grant permission under, (x) any standstill provision in any agreement to which the Company or any of its Subsidiaries is a party or (y) any confidentiality provision in any agreement to which the Company or any of its Subsidiaries is a party other than, with respect to this clause (y), any confidentiality provision, the waiver, amendment, modification or permission of which does not, and would not be reasonably likely to, facilitate, encourage or relate in any way to a Takeover Proposal or a potential the Takeover Proposal and (B) the Company shall, and shall cause its Subsidiaries to, enforce such confidentiality and standstill provisions of any such agreement, and the Company shall, and shall cause its Subsidiaries to, immediately take all steps within their power necessary to terminate any waiver that may have been heretofore granted, to any person other than Parent or any of Parent’s affiliates, under any such provisions.

(b) Notwithstanding anything to the contrary contained in Section 5.4(a), if at any time from and after the date of this Agreement and prior to obtaining the Company Shareholder Approval, the Company or any of its Subsidiaries, or any of its or their Representatives, directly or indirectly receives a bona fide, unsolicited written Takeover Proposal from any person that did not result from the Company’s, its affiliates’ or the Company’s or its affiliates’ Representatives’ failure to comply with the provisions of Section 5.4(a) and if the Company Board determines in good faith, after consultation with its outside financial advisors and outside legal counsel, that such Takeover Proposal constitutes or is reasonably likely to lead to a Company Superior Proposal, then the Company and any of its Subsidiaries, and any of its or their Representatives, may, directly or indirectly, (i) furnish, pursuant to an Acceptable Confidentiality Agreement, information (including non-public information) with respect to the Company and its Subsidiaries, and afford access to the business, properties, assets, employees, officers, contracts, books and records of the Company and its Subsidiaries, to the person who has made such Takeover Proposal and its Representatives and potential sources of financing; provided that the Company shall substantially concurrently with the delivery to such person provide to Parent any non-public information concerning the Company or any of its Subsidiaries that is provided or made available to such person or its Representatives unless such non-public information has been previously provided or made available to Parent and (ii) engage in or otherwise participate in discussions or negotiations with the person making such Takeover Proposal and its Representatives and potential sources of financing regarding such Takeover Proposal. As used this Section 5.4, “Acceptable Confidentiality Agreement” means any customary confidentiality agreement that contains provisions that are no less restrictive to the third party executing such agreement in the aggregate than those applicable to Parent that are contained in the Confidentiality Agreement; provided that such confidentiality agreement shall not prohibit compliance by the Company with any of the provisions of this Section 5.4.

(c) The Company shall promptly (and in no event later than 24 hours after receipt) notify, orally and in writing, Parent after receipt by the Company or any of its Subsidiaries, or any of its or their Representatives, of any Takeover Proposal, including of the identity of the person making the Takeover Proposal and the material terms and conditions thereof, and shall promptly (and in no event later than 24 hours after receipt) provide unredacted copies to Parent of any written proposals, indications of interest, and/or draft agreements received from the person making the Takeover Proposal (or its Representatives) relating to such Takeover Proposal. The

Company shall keep Parent reasonably informed, on a prompt basis, as to the status of (including changes to any material terms of, and any other material developments with respect to) such Takeover Proposal (including by promptly (and in no event later than 24 hours after receipt) providing to Parent unredacted copies of any additional or revised written proposals, indications of interest, and/or draft agreements relating to such Takeover Proposal). The Company agrees that it and its Subsidiaries will not enter into any agreement with any person subsequent to the date of this Agreement which prohibits the Company from providing any information to Parent in accordance with this Section 5.4.

(d) Except as expressly permitted by this Section 5.4(d) or Section 5.4(e), neither the Company Board nor any committee thereof shall (i) (A) fail to include the Company Board Recommendation in the Proxy Statement/Prospectus, (B) change, qualify, withhold, withdraw or modify, or authorize or publicly propose to change, qualify, withhold, withdraw or modify, in a manner adverse to Parent the Company Board Recommendation, (C) take any formal action or make any recommendation or public statement in connection with a tender offer or exchange offer (other than a recommendation against such offer or a customary “stop, look and listen” communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) (it being understood that the Company Board may refrain from taking a position with respect to such tender offer or exchange offer until the close of business as of the tenth business day after the commencement of such tender offer or exchange offer pursuant to Rule 14d-9(f) under the Exchange Act without such action being considered a Company Adverse Recommendation Change), or (D) adopt, approve or recommend, or publicly propose to adopt, approve or recommend, to the Company Shareholders a Takeover Proposal (any action described in this clause (i) being referred to as a “Company Adverse Recommendation Change”), or (ii) authorize, cause or permit the Company or any of its Subsidiaries to enter into any letter of intent, agreement, commitment or agreement in principle with respect to any Takeover Proposal (other than (x) an Acceptable Confidentiality Agreement entered into in accordance with Section 5.4(b) or (y) in accordance with Section 7.1(j)). Notwithstanding anything to the contrary set forth in this Agreement, at any time prior to receipt of the Company Shareholder Approval, the Company Board may make a Company Adverse Recommendation Change (i) in response to a Company Intervening Event, or (ii) after receipt of a bona fide, unsolicited Takeover Proposal, which the Company Board determines in good faith, after consultation with its outside financial advisors and outside legal counsel is a Company Superior Proposal, if and only if, (x) in the case of clause (ii), such Takeover Proposal was received after the date hereof and did not result from a breach of the provisions of this Section 5.4 and (y) in the case of clauses (i) and (ii), the Company Board has determined in good faith after consultation with the Company’s outside financial advisors and outside legal counsel that the failure to take such action would be inconsistent with the fiduciary duties of the Company Board under applicable Law and the Company complies with Section 5.4(e).

(e) Prior to making such Company Adverse Recommendation Change (i) in response to a Company Intervening Event, the Company shall provide Parent with at least four business days’ prior written notice of its intention to effect a Company Adverse Recommendation Change and specifying, in reasonable detail, the reasons therefor (including the material facts and circumstances related to the applicable Company Intervening Event), and during such four business day period, the Company has negotiated, and has caused its Representatives to negotiate, in good faith with Parent during such notice period, to the extent Parent wishes to negotiate, to

enable Parent to propose revisions to the terms of this Agreement in a manner that would obviate the need to effect a Company Adverse Recommendation Change or (ii) in connection with a Company Superior Proposal, (1) the Company shall provide Parent with at least four business days’ prior written notice of its intention to take such action (which notice shall specify the material terms and conditions of any such Company Superior Proposal) and specifying, in reasonable detail, the material terms and conditions of the Takeover Proposal, (2) the Company has negotiated, and has caused its Representatives to negotiate, in good faith with Parent during such notice period, to the extent Parent wishes to negotiate, to enable Parent to propose revisions to the terms of this Agreement such that it would cause such Company Superior Proposal to no longer constitute a Company Superior Proposal, (3) following the end of such notice period, the Company Board shall have considered in good faith any revisions to the terms of this Agreement proposed in writing by Parent, and shall have determined, after consultation with its outside financial advisors and outside legal counsel, that the Company Superior Proposal would nevertheless continue to constitute a Company Superior Proposal if the revisions proposed by Parent were to be given effect, and (4) in the event of any change to any of the material financial terms (including the form, amount and timing of payment of consideration) or any other material terms of such Company Superior Proposal, the Company shall, in each case, have delivered to Parent an additional notice consistent with that described in clause (1) of this Section 5.4(e) and a new notice period under clause (1) of this Section 5.4(e) shall commence (except that the four business day notice period referred to in clause (1) of this Section 5.4(e) shall instead be equal to the longer of (x) two business days and (y) the period remaining under the notice period under clause (1) of this Section 5.4(e) immediately prior to the delivery of such additional notice under this clause (4)) during which time the Company shall be required to comply with the requirements of this Section 5.4(e) anew with respect to such additional notice, including clauses (1) through (4) above of this Section 5.4(e).

(f) Nothing contained in this Section 5.4 shall prohibit the Company or the Company Board from taking and disclosing to the Company Shareholders a position contemplated by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act or from making any “stop, look and listen” communication or any other similar disclosure to the Company Shareholders pursuant to Rule 14d-9(f) under the Exchange Act if, in the determination in good faith of the Company Board, after consultation with outside counsel, the failure so to disclose would be inconsistent with its fiduciary duties under applicable Law or obligations under applicable federal securities Law of the Company Board; provided that this Section 5.4(f) shall not permit the Company Board to make a Company Adverse Recommendation Change except to the extent permitted by this Section 5.4.

Section 5.5 No Solicitation by Parent.

(a) Except as expressly permitted by this Section 5.5, Parent shall, shall cause each of its affiliates and its and their respective officers, directors and employees to, and shall use its reasonable best efforts to cause its and their other Representatives to: (i) immediately cease any solicitation, knowing encouragement, discussions or negotiations with any persons that may be ongoing with respect to or may reasonably be expected to lead to a Takeover Proposal, and promptly instruct (to the extent it has contractual authority to do so and has not already done so prior to the date of this Agreement) or otherwise request, any person that has executed a confidentiality or non-disclosure agreement within the 24-month period prior to the date of this Agreement in connection with any actual or potential Takeover Proposal to return or destroy all

such information or documents or material incorporating confidential information in the possession of such person or its Representatives, and (ii) until the Effective Time or, if earlier, the termination of this Agreement in accordance with Article VII, not, directly or indirectly, (1) solicit, initiate or knowingly facilitate or knowingly encourage (including by way of furnishing non-public information) any inquiries regarding, or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, a Takeover Proposal, (2) engage in, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any other person any non-public information in connection with or for the purpose of encouraging or facilitating, a Takeover Proposal (other than, solely in response to an unsolicited inquiry, to refer the inquiring person to this Section 5.5 and to limit its conversation or other communication exclusively to such referral), or (3) approve, recommend or enter into, or propose to approve, recommend or enter into, any letter of intent or similar document, agreement, commitment or agreement in principle (whether written or oral, binding or nonbinding) with respect to a Takeover Proposal (other than (x) an Acceptable Confidentiality Agreement in accordance with Section 5.5(b) or (y) in accordance with Section 7.1(k)). Except to the extent necessary to take any actions that Parent or any third party would otherwise be permitted to take pursuant to this Section 5.5 (and in such case only in accordance with the terms hereof), (A) Parent and its Subsidiaries shall not release any third party from, or waive, amend or modify any provision of, or grant permission under, (x) any standstill provision in any agreement to which Parent or any of its Subsidiaries is a party or (y) any confidentiality provision in any agreement to which Parent or any of its Subsidiaries is a party other than, with respect to this clause (y), any confidentiality provision, the waiver, amendment, modification or permission thereof does not, and would not be reasonably likely to, facilitate, encourage or relate in any way to a Takeover Proposal or a potential the Takeover Proposal and (B) Parent shall, and shall cause its Subsidiaries to, enforce such confidentiality and standstill provisions of any such agreement, and Parent shall, and shall cause its Subsidiaries to, immediately take all steps within their power necessary to terminate any waiver that may have been heretofore granted, to any person other than the Company or any of the Company’s affiliates, under any such provisions.

(b) Notwithstanding anything to the contrary contained in Section 5.5(a), if at any time from and after the date of this Agreement and prior to obtaining the Parent Shareholder Approval, Parent or any of its Subsidiaries, or any of its or their Representatives, directly or indirectly receives a bona fide, unsolicited written Takeover Proposal from any person that did not result from Parent’s, its affiliates’ or Parent’s or its affiliates’ Representatives’ failure to comply with the provisions of Section 5.5(a) and if the Parent Board determines in good faith, after consultation with its outside financial advisors and outside legal counsel, that such Takeover Proposal constitutes or is reasonably likely to lead to a Parent Superior Proposal, then Parent and any of its Subsidiaries, and any of its or their Representatives, may, directly or indirectly, (i) furnish, pursuant to an Acceptable Confidentiality Agreement, information (including non-public information) with respect to Parent and its Subsidiaries, and afford access to the business, properties, assets, employees, officers, contracts, books and records of Parent and its Subsidiaries, to the person who has made such Takeover Proposal and its Representatives and potential sources of financing; provided that Parent shall substantially concurrently with the delivery to such person provide to the Company any non-public information concerning Parent or any of its Subsidiaries that is provided or made available to such person or its Representatives unless such non-public information has been previously provided or made available to the Company and (ii) engage in or otherwise participate in discussions or negotiations with the person making such Takeover

Proposal and its Representatives and potential sources of financing regarding such Takeover Proposal. As used in this Section 5.5, “Acceptable Confidentiality Agreement” means any customary confidentiality agreement that contains provisions that are no less restrictive to the third party executing such agreement in the aggregate than those applicable to the Company that are contained in the Confidentiality Agreement; provided that such confidentiality agreement shall not prohibit compliance by Parent with any of the provisions of this Section 5.5.

(c) Parent shall promptly (and in no event later than 24 hours after receipt) notify, orally and in writing, the Company after receipt by Parent or any of its Subsidiaries, or any of its or their Representatives, of any Takeover Proposal, including of the identity of the person making the Takeover Proposal and the material terms and conditions thereof, and shall promptly (and in no event later than 24 hours after receipt) provide unredacted copies to the Company of any written proposals, indications of interest, and/or draft agreements received from the person making the Takeover Proposal (or its Representatives) relating to such Takeover Proposal. Parent shall keep the Company reasonably informed, on a prompt basis, as to the status of (including changes to any material terms of, and any other material developments with respect to) such Takeover Proposal (including by promptly (and in no event later than 24 hours after receipt) providing to the Company unredacted copies of any additional or revised written proposals, indications of interest, and/or draft agreements relating to such Takeover Proposal). Parent agrees that it and its Subsidiaries will not enter into any agreement with any person subsequent to the date of this Agreement which prohibits Parent from providing any information to the Company in accordance with this Section 5.5.

(d) Except as expressly permitted by this Section 5.5(d) or Section 5.5(e), neither the Parent Board nor any committee thereof shall (i) (A) fail to include the Parent Board Recommendation in the Proxy Statement/Prospectus, (B) change, qualify, withhold, withdraw or modify, or authorize or publicly propose to change, qualify, withhold, withdraw or modify, in a manner adverse to the Company the Parent Board Recommendation, (C) take any formal action or make any recommendation or public statement in connection with a tender offer or exchange offer (other than a recommendation against such offer or a customary “stop, look and listen” communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) (it being understood that the Parent Board may refrain from taking a position with respect to such tender offer or exchange offer until the close of business as of the tenth business day after the commencement of such tender offer or exchange offer pursuant to Rule 14d-9(f) under the Exchange Act without such action being considered a Parent Adverse Recommendation Change), or (D) adopt, approve or recommend, or publicly propose to adopt, approve or recommend, to the Parent Shareholders a Takeover Proposal (any action described in this clause (i) being referred to as a “Parent Adverse Recommendation Change”), or (ii) authorize, cause or permit Parent or any of its Subsidiaries to enter into any letter of intent, agreement, commitment or agreement in principle with respect to any Takeover Proposal (other than (x) an Acceptable Confidentiality Agreement entered into in accordance with Section 5.5(b) or (y) in accordance with Section 7.1(k)). Notwithstanding anything to the contrary set forth in this Agreement, at any time prior to receipt of the Parent Shareholder Approval, the Parent Board may make a Parent Adverse Recommendation Change (i) in response to a Parent Intervening Event, or (ii) after receipt of a bona fide, unsolicited Takeover Proposal, which the Parent Board determines in good faith, after consultation with its outside financial advisors and outside legal counsel is a Parent Superior Proposal, if and only if, (x) in the case of clause (ii), such Takeover Proposal was received after

the date hereof and did not result from a breach of the provisions of this Section 5.5 and (y) in the case of clauses (i) and (ii), the Parent Board has determined in good faith after consultation with Parent’s outside financial advisors and outside legal counsel that the failure to take such action would be inconsistent with the fiduciary duties of the Parent Board under applicable Law and Parent complies with Section 5.5(e).

(e) Prior to making such Parent Adverse Recommendation Change (i) in response to a Parent Intervening Event, Parent shall provide the Company with at least four business days’ prior written notice of its intention to effect a Parent Adverse Recommendation Change and specifying, in reasonable detail, the reasons therefor (including the material facts and circumstances related to the applicable Parent Intervening Event), and during such four business day period, Parent has negotiated, and has caused its Representatives to negotiate, in good faith with the Company during such notice period, to the extent the Company wishes to negotiate, to enable the Company to propose revisions to the terms of this Agreement in a manner that would obviate the need to effect a Parent Adverse Recommendation Change or (ii) in connection with a Parent Superior Proposal, (1) Parent shall provide the Company with at least four business days’ prior written notice of its intention to take such action (which notice shall specify the material terms and conditions of any such Parent Superior Proposal) and specifying, in reasonable detail, the material terms and conditions of the Takeover Proposal, (2) Parent has negotiated, and has caused its Representatives to negotiate, in good faith with the Company during such notice period, to the extent the Company wishes to negotiate, to enable the Company to propose revisions to the terms of this Agreement such that it would cause such Parent Superior Proposal to no longer constitute a Parent Superior Proposal, (3) following the end of such notice period, the Parent Board shall have considered in good faith any revisions to the terms of this Agreement proposed in writing by the Company, and shall have determined, after consultation with its outside financial advisors and outside legal counsel, that the Parent Superior Proposal would nevertheless continue to constitute a Parent Superior Proposal if the revisions proposed by the Company were to be given effect, and (4) in the event of any change to any of the material financial terms (including the form, amount and timing of payment of consideration) or any other material terms of such Parent Superior Proposal, Parent shall, in each case, have delivered to the Company an additional notice consistent with that described in clause (1) of this Section 5.5(e) and a new notice period under clause (1) of this Section 5.5(e) shall commence (except that the four business day notice period referred to in clause (1) of this Section 5.5(e) shall instead be equal to the longer of (x) two business days and (y) the period remaining under the notice period under clause (1) of this Section 5.5(e) immediately prior to the delivery of such additional notice under this clause (4)) during which time Parent shall be required to comply with the requirements of this Section 5.5(e) anew with respect to such additional notice, including clauses (1) through (4) above of this Section 5.5(e).

(f) Nothing contained in this Section 5.5 shall prohibit Parent or the Parent Board from taking and disclosing to the Parent Shareholders a position contemplated by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act or from making any “stop, look and listen” communication or any other similar disclosure to the Parent Shareholders pursuant to Rule 14d-9(f) under the Exchange Act if, in the determination in good faith of the Parent Board, after consultation with outside counsel, the failure so to disclose would be inconsistent with its fiduciary duties under applicable Law or obligations under applicable federal securities Law of the Parent Board; provided that this Section 5.5(f) shall not permit the Parent Board to make a Parent Adverse Recommendation Change except to the extent permitted by this Section 5.5.

Section 5.6 Filings; Other Actions.

(a) As promptly as reasonably practicable following the date of this Agreement, Parent and the Company shall prepare and file with the SEC the Form S-4, which will include the Proxy Statement/Prospectus. Each of Parent and the Company shall use commercially reasonable efforts to have the Form S-4 declared effective under the Securities Act as promptly as reasonably practicable after such filing and to keep the Form S-4 effective as long as necessary to consummate the Merger and the other transactions contemplated hereby. Each of Parent and the Company will cause the Proxy Statement/Prospectus to be mailed to the Parent Shareholders and Company Shareholders, as applicable, as soon as reasonably practicable after the Form S-4 is declared effective under the Securities Act. Parent shall also take any action required to be taken under any applicable state or provincial securities laws in connection with the issuance and reservation of the Parent Class A Ordinary Shares in the Merger, and the Company shall furnish all information concerning the Company and the holders of Company Common Stock, or holders of a beneficial interest therein, as may be reasonably requested in connection with any such action. No filing of, or amendment or supplement to, the Form S-4 or the Proxy Statement/Prospectus will be made by Parent or the Company, as applicable, without the other’s prior consent (which shall not be unreasonably withheld, conditioned or delayed) and without providing the other Party a reasonable opportunity to review and comment thereon. Parent or the Company, as applicable, will advise the other promptly after it receives oral or written notice of the time when the Form S-4 has become effective or any supplement or amendment thereto has been filed, the issuance of any stop order, the suspension of the qualification of the Parent Class A Ordinary Shares for offering or sale in any jurisdiction, or any oral or written request by the SEC for amendment of the Proxy Statement/Prospectus or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information, and will promptly provide the other with copies of any written communication from the SEC or any state securities commission. If at any time prior to the Effective Time any information relating to Parent or the Company, or any of their respective affiliates, officers or directors, is discovered by Parent or the Company which should be set forth in an amendment or supplement to any of the Form S-4 or the Proxy Statement/Prospectus, so that any of such documents would not include a misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Party that discovers such information shall promptly notify the other Parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by law, disseminated to the Parent Shareholders and Company Shareholders, as applicable.

(b) The Company, acting through the Company Board, shall, in accordance with applicable Law and the Company Charter and Company Bylaws, duly call, give notice of, convene and hold an annual or special meeting of its shareholders (the “Company Shareholder Meeting”) as soon as reasonably practicable following execution of this Agreement for the purpose of approving by requisite vote this Agreement. The Company Board shall, subject to Section 5.4(d), include the Company Board Recommendation in the Proxy Statement/Prospectus and use its reasonable best efforts to obtain the Company Shareholder Approval. Notwithstanding anything in this Agreement to the contrary, unless this Agreement is terminated in accordance with Section 7.1 and subject to compliance with Section 5.4, the Company, regardless of whether the Company Board has approved, endorsed or recommended a Takeover Proposal or has withdrawn, modified or amended the Company Board Recommendation, will submit this Agreement for approval by

the Company Shareholders at such meeting.

(c) Parent, acting through the Parent Board, shall, in accordance with applicable Law and Parent’s articles of association, duly call, give notice of, convene and hold a general meeting of its shareholders (the “Parent Shareholder Meeting”) as soon as reasonably practicable following execution of this Agreement for the purpose of approving by requisite vote the Parent Shareholder Resolutions. The Parent Board shall, subject to Section 5.5(d), include the Parent Board Recommendation in the Proxy Statement/Prospectus and use its reasonable best efforts to obtain approval of the Parent Shareholder Resolutions. Notwithstanding anything in this Agreement to the contrary, unless this Agreement is terminated in accordance with Section 7.1 and subject to compliance with Section 5.5, Parent, regardless of whether the Parent Board has approved, endorsed or recommended a Takeover Proposal or has withdrawn, modified or amended the Parent Board Recommendation, will submit the Parent Shareholder Resolutions for approval by the Parent Shareholders at such meeting.

(d) Notwithstanding anything to the contrary contained in this Agreement, Parent or the Company, after consultation with the other Party hereto and subject to such other Party’s approval (which shall not be unreasonably withheld, conditioned or delayed), may adjourn or postpone the Parent Shareholder Meeting or the Company Shareholder Meeting, as applicable, to the extent it believes in good faith that such adjournment or postponement is necessary to ensure that any required supplement or amendment to the Proxy Statement/Prospectus is provided to its shareholders or, if as of the time for which the Parent Shareholder Meeting or the Company Shareholder Meeting is originally scheduled (as set forth in the Proxy Statement/Prospectus) there are insufficient Parent Class A Ordinary Shares or shares of Company Common Stock, as applicable, represented (either in person or by proxy) to constitute a quorum necessary to conduct business at such meeting.

(e) Parent and the Company will use their respective reasonable best efforts to hold the Parent Shareholder Meeting and the Company Shareholder Meeting simultaneously and as soon as reasonably practicable after the date of this Agreement and shall cooperate in good faith to coordinate the timing of the Parent Shareholder Meeting and the Company Shareholder Meeting with the Parties’ anticipated Closing Date.

Section 5.7 Efforts; Regulatory Approvals.

(a) Prior to the Closing, Parent, Merger Sub and the Company shall use their respective 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 any applicable Laws to consummate and make effective the Merger, including (i) the preparation and filing of all forms, registrations and notices required to be filed to consummate the Merger and the provision of information in connection therewith, (ii) the satisfaction of the conditions to consummating the Merger, (iii) taking all reasonable actions necessary to obtain (and cooperating with each other in obtaining) any consent, authorization, Order or approval of, or any exemption by, any third party, including any Governmental Entity (which actions shall include furnishing all information and documentary material required under the HSR Act or other antitrust, competition, foreign investment or similar Laws outside of the United States) required to be obtained or made by the Parent, Merger Sub, the Company or any of their respective Subsidiaries in connection with the

Merger or the taking of any action contemplated by this Agreement, and (iv) the execution and delivery of any additional instruments necessary to consummate the Merger and to fully carry out the purposes of this Agreement. Additionally, Parent, Merger Sub and the Company shall use reasonable best efforts to fulfill all conditions precedent to the Merger and shall not take any action after the date of this Agreement that would reasonably be expected to materially delay the obtaining of, or result in not obtaining, any consent, authorization, Order or approval of, or any exemption by, any such Governmental Entity necessary to be obtained prior to Closing. To the extent that transfers of any Permits issued by any Governmental Entity are required as a result of the execution of this Agreement or the consummation of the Merger (including Permits required pursuant to Environmental Laws), the Parties hereto shall use reasonable best efforts to effect such transfers.

(b) In furtherance and not in limitation of the other covenants contained in this Section 5.7, each of the Parent, Merger Sub, and the Company shall use its reasonable best efforts to take, or cause to be taken, any and all steps and to make, or cause to be made any and all undertakings necessary to resolve objections, if any, that any Relevant Authority may assert under the HSR Act and any other federal, state or foreign law designed to prohibit, restrict or regulate actions for the purpose or effect of monopolization or restraint of trade or reduction of competition (collectively, “Antitrust Laws”) or that regulates foreign investment (“Foreign Investment Laws”), with respect to this Agreement, and to avoid or eliminate each and every impediment under any Antitrust Law or Foreign Investment Laws that may be asserted by any Relevant Authority with respect to this Agreement, in each case, so as to enable the Closing to occur as promptly as practicable including (i) proposing, negotiating, committing to and effecting, by consent decree, hold separate order, or otherwise, the sale, divestiture or disposition of any businesses, assets, equity interests, product lines or properties of the Parent, Merger Sub and the Company (or any of their respective subsidiaries) or any equity interest in any joint venture held by Parent, Merger Sub and the Company (or any of their respective subsidiaries), (ii) creating, terminating, or divesting relationships, ventures, contractual rights or obligations of the Parent, Merger Sub and the Company or their respective Subsidiaries and (iii) otherwise taking or committing to take any action that would limit the Parent’s or the Merger Sub’s freedom of action with respect to, or its ability to retain or hold, directly or indirectly, any businesses, assets, equity interests, product lines or properties of the Parent, Merger Sub and the Company (including any of their respective Subsidiaries) or any equity interest in any joint venture held by the Parent, Merger Sub and the Company (or any of their respective Subsidiaries), in each case as may be required in order to obtain all approvals and consents required directly or indirectly under any Antitrust Law or Foreign Investment Laws, or to avoid the commencement of any action to prohibit the Closing of the Agreement under any Antitrust Law or Foreign Investment Laws, or to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other order in any action or proceeding seeking to prohibit the Closing of the Agreement or delay the Closing of the Agreement beyond the End Date, provided, however, that Parent shall not be required to take any actions under this Section 5.7 that would reasonably be expected to, individually or in the aggregate, result in a one-year loss of revenues determined in accordance with GAAP (as measured by the four full fiscal quarters for which financial statements are available immediately preceding the relevant measurement period) of more than $175.0 million on a combined basis for both the Company and its Subsidiaries and Parent and its Subsidiaries. Nothing in this Section 5.7(b) shall require by the Parent, Merger Sub and the Company to take or agree to take any action with respect

to its business or operations unless the effectiveness of such agreement or action is conditioned upon the Closing.

(c) The Company and Parent shall each keep the other apprised of the status of matters relating to the completion of the Merger and work cooperatively in connection with obtaining all required consents, authorizations, Orders or approvals of, or any exemptions by, any Governmental Entity undertaken pursuant to the provisions of this Section 5.7. In that regard, prior to the Closing, each Party shall promptly consult with one another with respect to, and provide any necessary information with respect to (and, in the case of correspondence, provide the other Parties (or their counsel) copies of), all filings made by such Party with any Governmental Entity or any other information supplied by such Party to, or correspondence with, a Governmental Entity in connection with this Agreement and the Merger. Each Party to this Agreement shall promptly inform the other Parties to this Agreement, and if in writing, furnish the other Party (or their counsel) with copies of (or, in the case of oral communications, advise the other Party (or their counsel) orally of) any communication from any Governmental Entity regarding the Merger, and permit the other Party to review and discuss in advance, and consider in good faith the views of the other Party in connection with, any proposed communication with any such Governmental Entity. If any Party or any Representative of such Party receives a request for additional information or documentary material, or other request for information, from any Governmental Entity with respect to the Merger, then such Party will use reasonable best efforts to make, or cause to be made, promptly and after consultation with the other Party, an appropriate response in substantial compliance with such request. Neither Party shall participate in any meeting or teleconference with any Governmental Entity where material issues would likely be discussed in connection with this Agreement and the Merger unless, so long as reasonably practicable, it consults with the other Party in advance and, to the extent permitted by such Governmental Entity, gives the other Party the opportunity to attend and participate thereat. Each Party shall furnish the other Party with copies of all correspondence, filings and communications (and memoranda setting forth the substance thereof) between it and any such Governmental Entity with respect to this Agreement and the Merger, and furnish the other Party with such necessary information and reasonable assistance as the other Party may reasonably request in connection with its preparation of necessary filings or submissions of information to any such Governmental Entity; provided, however, that materials provided pursuant to this Section 5.7 may be redacted (i) to remove references concerning the valuation of the Company and the Merger or other confidential information, (ii) as necessary to comply with contractual arrangements, and (iii) as necessary to address reasonable privilege concerns.

(d) The Company and Parent shall use reasonable best efforts to (i) file, as promptly as practicable, but in any event no later than ten (10) business days after the date of this Agreement, all notifications required under the HSR Act; and (ii) make any other required or advisable filings (as determined by Parent) under any antitrust, competition, foreign investment or similar Laws as promptly as practicable. In the event that the Parties receive a request for information or documentary material pursuant to the HSR Act or other request for information from any Governmental Entity, the Parties will use their respective reasonable best efforts to respond to such request as promptly as practicable, and counsel for both Parties will closely cooperate during the entirety of any such response process.

(e) Notwithstanding anything to the contrary contained herein, the Parties agree

that it is Parent’s sole right to control, direct and devise the strategy for all filings, notifications, submissions, communications and other dealings and decision-making in connection with the HSR Act and other antitrust, competition, foreign investment and similar Laws. Notwithstanding the foregoing, nothing in this Section 5.7(e) shall limit Parent’s obligations under Section 5.7(a), (b), (c) and (d).

Section 5.8 Takeover Statutes. If any “moratorium,” “control share acquisition,” “fair price,” “supermajority,” “affiliate transactions,” or “business combination statute or regulation” or other similar state or other anti-takeover Laws and regulations may become, or may purport to be, applicable to the Merger or any other transactions contemplated hereby, each of the Company and Parent shall grant such approvals and take such actions as are reasonably necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of such statute or regulation on the transactions contemplated hereby.

Section 5.9 Public Announcements. Parent and the Company shall use commercially reasonable efforts to develop a joint communications plan and each Party shall use commercially reasonable efforts to ensure that all press releases and other public statements with respect to the transactions contemplated hereby, to the extent they have not been previously issued or disclosed, shall be consistent with such joint communications plan. Unless otherwise required by applicable Law or by obligations pursuant to any listing agreement with or rules of any securities exchange, each Party shall consult with each other before issuing any press release or public statement with respect to the Merger and, subject to the requirements of applicable Law or the rules of any securities exchange, shall not issue any such press release or public statement prior to such consultation. Parent and the Company agree to issue a mutually acceptable initial joint press release announcing this Agreement.

Section 5.10 Indemnification and Insurance.

(a) Parent agrees that, to the fullest extent permitted under applicable Law, all rights to exculpation, indemnification and advancement of expenses for acts or omissions occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, existing as at the date of this Agreement in favor of the current or former directors, officers or employees, as the case may be, of the Company or its Subsidiaries as provided in their respective certificate of formation or bylaws or other organizational documents or in any agreement shall survive the Merger and shall continue in full force and effect in accordance with their terms. For a period of six years from the Effective Time, to the fullest extent permitted under applicable Law, Parent shall, and shall cause the Surviving Company to, maintain in effect any and all exculpation, indemnification and advancement of expenses provisions of the certificate of formation, bylaws or similar organizational documents of the Company and its Subsidiaries in effect as at the date of this Agreement or in any indemnification agreements of the Company or its Subsidiaries with any of their respective current or former directors, officers or employees in effect as at the date of this Agreement, and to the fullest extent permitted under applicable Law shall not amend, repeal or otherwise modify any such provisions or the exculpation, indemnification or advancement of expenses provisions of the organizational documents of the Company or its Subsidiaries in any manner that would adversely affect the rights thereunder of any individuals who immediately before the Effective Time were current or former directors, officers or employees

of the Company or any of its Subsidiaries; provided, however, that all rights to exculpation, indemnification and advancement of expenses in respect of any Action pending or asserted or any claim made within such period shall continue until the disposition of such Action or resolution of such claim.

(b) Parent shall, and shall cause the Surviving Company to, to the fullest extent permitted under applicable Law, indemnify and hold harmless (and advance funds in respect of each of the foregoing) each current and former director, officer or employee of the Company or any of its Subsidiaries and each person who served as a director, officer, member, trustee or fiduciary of another corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise if such service was at the request or for the benefit of the Company or any of its Subsidiaries (each, together with such person’s heirs, executors or administrators, an “Indemnified Party”), in each case against any costs or expenses (including advancing attorneys’ fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by applicable Law; provided, however, that the Indemnified Party to whom expenses are advanced provides an undertaking consistent with applicable Law and the Company Organizational Documents to repay such amounts if it is ultimately determined that such person is not entitled to indemnification), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (an “Action”), arising out of, relating to or in connection with any action or omission by them in their capacities as such occurring or alleged to have occurred whether before or after the Effective Time (including acts or omissions in connection with such Indemnified Party serving as an officer, director, employee or other fiduciary of any entity if such service was at the request or for the benefit of the Company). In the event of any such Action, Parent and the Surviving Company shall cooperate with the Indemnified Party in the defense of any such Action.

(c) For a period of six years from the Effective Time, Parent and the Surviving Company shall cause to be maintained in effect the coverage provided by the policies of directors’ and officers’ liability insurance and fiduciary liability insurance in effect as of the date hereof by the Company and its Subsidiaries with respect to matters existing or arising on or before the Effective Time (provided that Parent may substitute these for policies with a carrier with reasonably comparable credit ratings to the existing carrier of at least the same coverage and amounts and containing terms and conditions that it reasonably considers are no less favorable to the insured or, if insurance coverage that is no less favorable is unavailable, the best available coverage); provided, however, that Parent shall not be required to pay an annual premium in excess of 300% of the last annual premium paid by the Company prior to the date hereof in respect of the coverages (the “Maximum Amount”) required to be obtained pursuant hereto, but in such case shall purchase as much coverage as reasonably practicable for such amount. If the Company or Parent elects, then the Company or Parent, as applicable, may, prior to the Effective Time, purchase a “tail policy” with respect to acts or omissions occurring or alleged to have occurred prior to the Effective Time that were committed or alleged to have been committed by such Indemnified Parties in their capacity as such; provided that in no event shall the cost of such policy, if purchased by the Company, exceed six (6) times the Maximum Amount and, if such a “tail policy” is purchased, Parent shall have no further obligations under this Section 5.10(c).

(d) Parent shall, to the fullest extent permitted under applicable Law, pay all

reasonable expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in enforcing the indemnity and other obligations provided in this Section 5.10.

(e) The rights of each Indemnified Party under this Section 5.10 shall be in addition to, and not in limitation of, any other rights such Indemnified Party may have under the certificate of incorporation or bylaws or other organizational documents of the Company or any of its Subsidiaries or the Surviving Company, any other indemnification arrangement, the TBOC or otherwise.

(f) In the event that Parent, the Surviving Company or any of its successors or assigns shall (i) consolidate with or merge into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfer all or substantially all its properties and assets to any person, then, and in each such case, Parent shall cause proper provision to be made so that the successor and assign of Parent or the Surviving Company assumes the obligations set forth in this Section 5.10.

(g) The obligations of Parent under this Section 5.10 shall not be terminated, amended or modified in any manner so as to adversely affect any Indemnified Party (including their successors, heirs and legal representatives) to whom this Section 5.10 applies without the consent of such Indemnified Party. It is expressly agreed that, notwithstanding any other provision of this Agreement that may be to the contrary, (i) the Indemnified Parties to whom this Section 5.10 applies shall be third-party beneficiaries of this Section 5.10, and (ii) this Section 5.10 shall survive consummation of the Merger and shall be enforceable by such Indemnified Parties and their respective successors, heirs and legal representatives against Parent and its successors and assigns.

Section 5.11 Control of Operations. Without in any way limiting any Party’s rights or obligations under this Agreement, the Parties understand and agree that (a) nothing contained in this Agreement shall give Parent or the Company, directly or indirectly, the right to control or direct the other Party’s operations prior to the Effective Time and (b) prior to the Effective Time, each of Parent and the Company shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its operations.

Section 5.12 Section 16 Matters. Prior to the Effective Time, Parent and the Company shall take all such steps as may be required to cause any dispositions of Company Common Stock (including derivative securities with respect to Company Common Stock) or acquisitions of Parent Ordinary Shares (including derivative securities with respect to Parent Ordinary Shares) resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 5.13 Transaction Litigation. Each Party shall provide the other Party prompt written notice of any litigation brought by any shareholder of that Party against such Party, any of its Subsidiaries and/or any of their respective directors relating to the Merger, this Agreement or any of the transactions contemplated hereby. Unless, in the case of such litigation with respect to the Company, the Company Board has made or is considering making a Company Adverse

Recommendation Change, the Company shall give Parent the opportunity to participate (at Parent’s expense) in the defense or settlement of any shareholder litigation against the Company and/or its directors or executive officers relating to the transactions contemplated by this Agreement, including the Merger. The Company agrees that it shall not settle or offer to settle any litigation commenced prior to or after the date of this Agreement against the Company or its directors, executive officers or similar persons by any shareholder of the Company relating to this Agreement, the Merger or any other transaction contemplated hereby without the prior written consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed).

Section 5.14 NYSE Listing. Parent shall use its best efforts to cause the Parent Class A Ordinary Shares to be issued in the Merger to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Closing Date.

Section 5.15 Tax Matters. The Parties shall (and shall cause their respective affiliates to) use commercially reasonable efforts to ensure that Section 7874 of the Code, the regulations promulgated thereunder, or official interpretation thereof as set forth in published guidance by the IRS (the “Expatriated Entity Rules”), should not apply in such a manner so as to cause Parent to be treated as a “domestic corporation” for U.S. federal income Tax purposes as a result of the Merger, including by (i) not taking any action that such Party knows (or not failing to take any action which failure such Party knows) is reasonably likely to result in such “domestic corporation” treatment, and (ii) negotiating in good faith such amendments to this Agreement as may be reasonably required in order to prevent such “domestic corporation” treatment (it being understood that no Party will be required to agree to any such amendment). If any Party is, or should reasonably become, aware of any fact or circumstance that such Party may reasonably expect would cause the representations in any of Section 3.14(d) or Section 4.14(c) to be untrue, then such Party shall promptly notify the other Parties. The Parties agree to execute certificates, at such time or times as may be reasonably requested by any Party, in form and substance reasonably acceptable to the requesting Party, containing appropriate representations establishing that the Expatriated Entity Rules should not apply in such a manner so as to cause Parent to be treated as a “domestic corporation” for U.S. federal income Tax purposes as a result of the Merger.

Section 5.16 Certificate of Non-USRPHC Status. The Company shall deliver to Parent at the Closing a certification by the Company that meets the requirements of Treasury Regulations Section 1.1445-2(c)(3) and Treasury Regulations Section 1.897-2(h)(1)(i), dated within 30 days prior to the Closing Date and in form and substance reasonably acceptable to Parent along with written authorization for Parent to deliver such certification to the IRS on behalf of the Company upon Closing.

The Company hereby consents to Parent’s inclusion of any audited or unaudited financial statements, including those contained in any Company SEC Documents, relating to and prepared by the Company reasonably requested by Parent to be used in any financing or any filings that Parent desires to make with the SEC. In addition, the Company will use commercially reasonable efforts, at Parent’s sole cost and expense, to obtain customary comfort letters from PricewaterhouseCoopers LLP regarding financial statements of the Company as reasonably requested by the lead underwriter(s) or initial purchaser(s) in connection with any registered or private offering or otherwise and to obtain the consent of PricewaterhouseCoopers LLP to the

inclusion of the financial statements referenced above in appropriate filings with the SEC. Prior to the Closing, the Company will use commercially reasonable efforts to provide Parent such information regarding the Company’s business, and make available such personnel, as Parent may reasonably request in order to assist Parent in connection with any financing activities, including any public offerings to be registered under the Securities Act or private offerings, if permitted under Section 5.2(b). Parent shall indemnify, defend, and hold harmless the Company, its Subsidiaries and their respective Representatives from and against any and all losses suffered or incurred by them in connection with (a) any action taken by them at the request of Parent or Merger Sub pursuant to this Section 5.17 or in connection with any registered or private offering of Parent or (b) any information utilized in connection therewith (other than information provided by the Company and its Subsidiaries specifically for inclusion or incorporation by reference therein).

Section 5.18 Employee Matters.

(a) At the Effective Time, Parent and its Subsidiaries will continue the employment of all of the employees who are employed by the Company or any of its Subsidiaries as of the day immediately prior to the Effective Time (the “Affected Employees”) initially at the same salaries and wages of such employees immediately prior to the Effective Time. During the period from the Effective Time to and including the one year anniversary of the Closing Date, Parent and its Subsidiaries (i) shall provide each Affected Employee with an annual salary rate or hourly wage rate, as applicable, that is no less favorable to such Affected Employee than the salary rate or wage rate provided to such Affected Employee immediately prior to the Effective Time, and (ii) shall provide Affected Employees who are so employed by the Company or its Subsidiaries as of the day immediately prior to the Effective Time, in the aggregate, with employee compensation and benefits (excluding equity compensation and long-term incentives) that are no less favorable in the aggregate than those provided by the Company or its Subsidiaries immediately prior to the Effective Time; provided, however, that Parent may transition Affected Employees to Parent’s bonus and incentive compensation plans at any time in Parent’s discretion and, following the end of the fiscal year or benefit plan year, as applicable, in which the Closing Date occurs, Parent may transition Affected Employees to other compensation and benefit plans providing compensation and benefits that are substantially comparable in the aggregate to those provided to Parent’s other similarly situated employees. Nothing in this Agreement shall be considered a contract between Parent and its Subsidiaries and any Affected Employee or consideration for, or inducement with respect to, any such employee’s continued employment and, without limitation, all such employees are and will continue to be considered to be employees at will pursuant to the applicable employment at will laws or doctrines, subject to any express written agreement to the contrary with such employee. From and after the Effective Time, Parent shall honor, and shall cause its Subsidiaries to honor, each change in control or severance agreement between the Company and its Subsidiaries and any employee thereof and to perform the obligations of the Company thereunder, and Parent shall provide, or cause its Subsidiaries to provide, relocation benefits in accordance with Company policy as in effect on the date of this Agreement to any Affected Employee who becomes entitled to severance benefits following the Effective Time pursuant to any Company Benefit Plan.

(b) With respect to each Affected Employee, Parent shall credit, or cause its Subsidiaries to credit, the period of employment and service recognized by the applicable employer immediately prior to the Effective Time (for purposes of its corresponding plans,

programs, policies or similar employment-related arrangements) to have been employment and service with Parent for purposes of determining the Affected Employee’s eligibility to join (subject to satisfaction of all non-service related eligibility criteria) and vesting (but not benefit accrual for any purpose other than vacation pay, severance and termination pay and sick leave) under all employee benefit plans, programs, policies or similar employment related arrangements of Parent and its Subsidiaries in which the Affected Employee is eligible to participate; provided, however, that no such credit shall be provided to the extent that it would result in a duplication of credit or benefits. Parent shall waive, and to the extent necessary to effect the terms hereof, shall use commercially reasonable efforts to cause the relevant insurance carriers and other third parties to waive, any restrictions and limitations for medical conditions existing as of the Effective Time of those Affected Employees and their dependents who were covered immediately prior to the Effective Time under a group health plan maintained by the Company, Parent or their Subsidiaries, but only to the extent that such medical condition would be covered by Parent’s group health plan if it were not a pre-existing condition and only to the extent that such limitations would not have applied under the applicable group health plan covering the Affected Employee prior to the Effective Time. Further, Parent shall offer, or cause its Subsidiaries to offer, at the Effective Time to each Affected Employee coverage under a group health plan (as defined in Section 5000(b)(1) of the Code) which credits such Affected Employee towards the deductibles, coinsurance and maximum out-of-pocket provisions imposed under such group health plan, for the plan year during which the Effective Time (or such later date as the Affected Employees participate in such group health plan) occurs, with any applicable expenses already incurred during such year under the Company’s or Parent’s group health plan.

(c) The Company and Parent agree to cooperate in good faith to establish a process to promptly integrate the Company Benefit Plans and the Parent Benefit Plans following the Effective Time.

(d) Promptly following the Effective Time, Parent shall pay, or shall cause its Subsidiaries to pay, to each Affected Employee who was employed by the Company or its Subsidiaries immediately prior to the Effective Time an amount, to the extent then unpaid, equal to the unpaid portion of any annual incentive bonus to which the Affected Employee were be entitled under the applicable Company annual bonus plan for the year prior to the year in which the Effective Time occurs.

(e) Except with respect to offers of employment to prospective new employees in the ordinary course of business consistent with past practices, the Company and Parent agree that they shall not make, and shall cause their respective Subsidiaries not to make, any representations or promises, oral or written, to any of their employees concerning continued employment following the Effective Time, or the terms and conditions of that employment, except in writing with the prior written consent of the other party.

(f) Notwithstanding the foregoing, nothing in this Agreement, whether express or implied, shall be treated as an amendment or other modification of any Company Benefit Plan, Parent Benefit Plan or other compensation or benefit plan, program or arrangement of the Company, Parent or their Subsidiaries, or shall limit the right of the Company, Parent or any of their Subsidiaries, to amend, terminate or otherwise modify any such plan or arrangement or to terminate the employment of any Affected Employee at any time. No Affected Employee or other

individual is an intended third party of this Section 5.18 and no such person shall have any right to enforce any provision of this Section 5.18.

(g) For the avoidance of doubt, upon the Effective Time, a “change in control” shall be deemed to have occurred for purposes of all Company Benefit Plans and other employee plans, programs and arrangements of the Company that use “change in control” or a similar term.

Section 5.19 Obligations of Merger Sub and the Surviving Company. Parent shall take all action necessary to cause Merger Sub and the Surviving Company to perform their respective obligations under this Agreement and to consummate the transactions contemplated hereby, including the Merger, upon the terms and subject to the conditions set forth in this Agreement.

Section 5.20 Intercompany Structure. Within 30 days after the date hereof, Parent shall deliver to the Company, for the Company’s review and approval (which approval shall not be unreasonably conditioned, withheld or delayed), a plan by which Parent can effect, prior to the Effective Time, certain intercompany transfers of equity and debt among Parent, Merger Sub and any other affiliates of Parent, including any newly-formed or to-be-formed entities, in accordance with the principles set forth in Schedule 5.20. The consummation of the transactions contemplated hereby shall be effected in accordance with such plan, which shall not be modified without the Company’s approval (which approval shall not be unreasonably conditioned, withheld or delayed). Parent and the Company shall work together in good faith in order to achieve an efficient intercompany structure among Parent, such affiliates and Merger Sub in connection with the consummation of the transactions contemplated hereby.

Section 5.21 Company Bond Redemption. At least 45 but not more than 75 days prior to the Closing Date, if requested by Parent, the Company shall deliver a redemption notice to the holders (the “Noteholders”) of the Company’s 6.50% Senior Notes due 2020 (the “Company Notes”) providing for the redemption of such Company Notes by the Company substantially concurrently with the Closing. The redemption of such Company Notes, if any, shall be made pursuant to Section 4.07 of that certain Indenture dated as of January 18, 2012 among the Company, the subsidiary guarantors of the Company party thereto and Wells Fargo Bank, National Association, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture thereto dated January 18, 2012 (as so supplemented, the “Indenture”), and shall be conditioned upon the Closing. The Company shall comply with the provisions in Article IV of the Indenture relating to the redemption of the Company Notes and shall provide Parent a reasonable opportunity to review and comment on any documents delivered by the Company to the Noteholders or the Trustee in connection with the redemption.

Notwithstanding anything to the contrary in this Agreement, if the Company Termination Fee or Parent Termination Fee shall become due and payable in accordance with this Section 7.3, from and after such termination and payment thereof pursuant to and in accordance with this Section 7.3, the Party paying the Company Termination Fee or Parent Termination Fee shall have no further liability of any kind for any reason in connection with this Agreement or the termination contemplated hereby other than as provided under this Section 7.3. Payment by the Company of the Company Termination Fee or payment by Parent of the Parent Termination Fee, as applicable, shall not relieve the Company or Parent, as applicable, from any liability or damage resulting from fraud or a willful and material breach by such Party of this Agreement; provided that, notwithstanding the foregoing, (A) if Parent accepts payment of the Company Termination Fee in connection with a termination pursuant to Section 7.1(i)(ii), none of the Company, any of its Subsidiaries or any of their respective former, current or future officers, directors, partners, shareholders, managers, members, affiliates or agents shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated hereby, and (B) if the Company accepts payment of the Parent Termination Fee in connection with a termination pursuant to Section 7.1(h)(ii), none of Parent, any of its Subsidiaries or any of their respective former, current or future officers, directors, partners, shareholders, managers, members, affiliates or agents shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated hereby. Each of the Parties hereto acknowledges that neither the Company Termination Fee nor the Parent Termination Fee is intended to be a penalty, but rather liquidated damages in a reasonable amount that will compensate a Party in the circumstances in which such fee is due and payable and which do not involve fraud or willful and material breach, for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision. In no event shall the Company or Parent be entitled to more than one payment of the

Company Termination Fee or Parent Termination Fee, as the case may be, in connection with a termination of this Agreement pursuant to which the Company Termination Fee or Parent Termination Fee is payable. “Expense Reimbursement Amount” means an amount, not to exceed $10,000,000, equal to the reasonable out-of-pocket fees and expenses, incurred by or on behalf of the person entitled to payment, in connection with the preparation, negotiation, execution and performance of this Agreement and the transactions contemplated hereby, but excluding any VAT for which Parent (or any member of a VAT grouping arrangement of which Parent is a member) is entitled to a refund, repayment or credit from any relevant tax authority.

(c) Each of the Company and Parent acknowledges that the agreements contained in this Section 7.3 are an integral part of the transactions contemplated hereby, and that, without these agreements, the Company and Parent would not enter into this Agreement. Accordingly, if the Company or Parent fails to pay in a timely manner any amount due pursuant to this Section 7.3, then (i) the Company or Parent, as applicable, shall reimburse the Party entitled to the Company Termination Fee or Parent Termination Fee for all costs and expenses (including disbursements and reasonable fees of counsel) incurred in the collection of such overdue amount, including in connection with any related Actions commenced and (ii) the Company or Parent, as applicable, shall pay to the Party entitled to the Company Termination Fee or Parent Termination Fee interest on such amount from and including the date payment of such amount was due to but excluding the date of actual payment at the prime rate set forth in The Wall Street Journal in effect on the date such payment was required to be made plus 2%.

(d) The Company confirms that it is established outside of the European Union for VAT purposes.
