Capitalized terms used but not defined herein shall the meanings given to them in the Merger Agreement.

Merger Consideration

Subject to the terms and conditions set forth in the Merger Agreement, at the effective time of the Merger (the "Effective Time"), each share of Class A Common Stock of the Company, par value $0.0001 per share (collectively, the "Class A Common Shares") and each share of Class B Common Stock of the Company, par value $0.0001 per share (collectively, the "Class B Common Shares" and, together with the Class A Common Shares, the "Common Shares") (including any Common Shares to the extent issued in accordance with the terms of the Merger Agreement and the Convertible Notes Indenture, but excluding (i) Common Shares held by the Company as treasury shares or owned by Parent, Merger Sub, or any other Subsidiary of Parent immediately prior to the Effective Time and (ii) Dissenting Company Shares) issued and outstanding immediately prior to the Effective Time will automatically be converted into the right to receive $113.00 in cash, without interest (the "Merger Consideration").

Pursuant to the Merger Agreement, at or immediately prior to the Effective Time:

If the Merger is consummated, the Company's securities will be delisted from the Nasdaq Global Select Market and deregistered under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as promptly as practicable after the Effective Time.

Closing Conditions

The consummation of the Merger (the "Closing") is subject to certain customary mutual conditions, including (i) the approval of the Company's stockholders holding a majority of the voting power of the outstanding Common Shares entitled to vote on the adoption of the Merger Agreement, voting together as a single class (the "Company Stockholder Approval"), (ii) the absence of any order or law issued by any governmental authority of competent jurisdiction prohibiting, rendering illegal or enjoining the consummation of the Merger, (iii) the expiration or termination of any waiting period (and any extensions thereof) applicable to the consummation of the Merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and any commitment to, or agreement with, any governmental authority to delay or not consummate the Merger, and (iv) the receipt of all required consents, approvals, notifications or filings from or to any governmental authority under the antitrust and foreign investment laws of certain other jurisdictions.

The obligation of each party to consummate the Merger is also conditioned upon (i) performance and compliance by the other party in all material respects with its pre-Closing obligations and covenants under the Merger Agreement, (ii) the accuracy of the representations and warranties of the other party as of the Closing (subject to customary materiality qualifiers), and (iii) in Parent's case, the absence of a continuing material adverse effect with respect to the Company and its subsidiaries, taken as a whole. The Merger is not subject to a financing condition.

Representations and Warranties and Covenants

The Company and Parent have each made customary representations, warranties and covenants in the Merger Agreement. Subject to certain exceptions, the Company has agreed, among other things, to covenants relating to the conduct of its business during the interim period between the execution of the Merger Agreement and Closing. In addition, subject to certain exceptions, the Company has agreed to covenants relating to (i) the submission of the Merger Agreement to the Company's stockholders at a meeting thereof for approval (the "Company Stockholders Meeting") and (ii) recommendation by the board of directors of the Company (the "Board") in favor of the adoption by the Company's stockholders of the Merger Agreement.

No Solicitation

The Company is subject to customary "no-shop" restrictions on the Company's ability to solicit alternative acquisition proposals, to furnish information to, and participate in discussions or negotiations with, third parties regarding any alternative acquisition proposals, subject to a customary "fiduciary out" provision that allows the Company, under certain specified circumstances, to furnish information to, and participate in discussions or negotiations with, third parties with respect to an alternative acquisition proposal if the Board determines in good faith, after consultation with its financial advisors and outside legal counsel, that such alternative acquisition proposal either (i) constitutes a superior proposal or (ii) would reasonably be expected to lead to a superior proposal, and that failure to engage in negotiations or discussions with such third parties would be inconsistent with its fiduciary duties.

Termination and Fees

The Merger Agreement contains certain customary termination rights for the Company and Parent. Parent and the Company may agree to terminate the Merger Agreement by mutual written consent. Either the Company or Parent may terminate the Merger Agreement if (i) the Merger has not been consummated on or before October 30, 2025 (the "End Date") or, if the Closing has not occurred by the End Date solely due to a failure to obtain required regulatory approvals, April 30, 2026 (the "Extended End Date"), (ii) any applicable law or final, irreversible and non-appealable order that permanently prohibits, renders illegal or enjoins the Merger is issued by any government authority of competent jurisdiction, (iii) the Company Stockholder Approval is not obtained at the Company Stockholders Meeting at which a vote on the adoption of the Merger Agreement is held, or (iv) the other party breaches any representation, warranty or covenant that results in the failure of the related closing condition to be satisfied, subject to a cure period in certain circumstances. In addition, the Company may, under certain circumstances, terminate the Merger Agreement in order for the Company to enter concurrently into a definitive written agreement with respect to an unsolicited superior acquisition proposal, subject to the Company having first complied with its obligations under the "no-shop" provisions, including Parent's matching rights and payment of the Company Termination Fee (as defined below) to Parent, as set forth in the Merger Agreement. In addition, Parent may, under certain circumstances, terminate the Merger Agreement if the Board changes or adversely modifies its recommendation that the Company's stockholders vote in favor of adopting the Merger Agreement.

The Company is required to pay to Parent a one-time fee equal to $372.0 million (the "Company Termination Fee") if the Merger Agreement is terminated (i) by the Company in order for the Company to enter into a definitive written agreement with respect to an unsolicited superior acquisition proposal, (ii) by Parent because the Board changes or adversely modifies its recommendation that the Company's stockholders vote in favor of adopting the Merger Agreement, or (iii) prior to the receipt of the Company Stockholder Approval, by (a) either party due to failure to close by the End Date (or Extended End Date, as applicable) or failure to obtain the Company Stockholder Approval or (b) Parent in connection with the Company breaching its representations, warranties or covenants in a manner that would cause the related closing conditions to not be satisfied (subject to a cure period in certain circumstances), but only if, in the case of this clause (iii), an alternative acquisition proposal was publicly announced (or solely in the case of clause (b) made to the Board) after the date of the Merger Agreement and prior to the Company's Stockholders Meeting, and not withdrawn, and, within 12 months after termination of the Merger Agreement, a definitive agreement for the alternative acquisition proposal is entered into or consummated.

Parent is required to pay to the Company a one-time fee equal to $638.0 million (the "Parent Termination Fee") if the Merger Agreement is terminated by the Company or Parent due to (i) failure to close by the End Date (or Extended End Date, as applicable) or (ii) any applicable law or final, irreversible non-appealable order that permanently prohibits, renders illegal or enjoins the Merger is issued by any government authority of competent jurisdiction, and at such time, the only conditions to the closing not satisfied are (a) receipt of the required regulatory approvals or (b) only in the case of clause (ii) the absence of any order or law issued by any governmental authority of competent jurisdiction prohibiting, rendering illegal or enjoining the consummation of the Merger, solely related to competition and foreign direct investment laws.

The Merger Agreement also provides that either party may specifically enforce the other party's obligations under the Merger Agreement under certain circumstances.

Voting Agreement

On October 30, 2024, concurrently with the execution and delivery of the Merger Agreement, James R. Scapa, including his affiliated entities and trusts (the "Supporting Shareholders"), have, together with the Company, entered into a Voting and Support Agreement (the "Voting Agreement") with Parent, pursuant to which the

Supporting Shareholders agree, among other things, to (i) vote all of the Common Shares held by them in favor of the adoption of the Merger Agreement at the Company Stockholders Meeting, (ii) not transfer their Common Shares, subject to certain limited exceptions, and (iii) comply with the non-solicitation obligations in the Merger Agreement (described above). In the aggregate, the Voting Agreement obligates the Supporting Shareholders to vote approximately 54% of the outstanding Common Shares in favor of adoption of the Merger Agreement.

This communication contains "forward-looking statements" within the Private Securities Litigation Reform Act of 1995. Any statements contained in this communication that are not statements of historical fact, including statements regarding the proposed transaction, including the expected timing and closing of the proposed transaction; the Company's ability to consummate the proposed transaction; the expected benefits of the proposed transaction and other considerations taken into account by the Board of Directors in approving the proposed transaction; the amounts to be received by stockholders and expectations for the Company prior to and following the closing of the proposed transaction, may be deemed to be forward-looking statements. All such forward-looking statements are intended to provide management's current expectations for the future of the Company based on current expectations and assumptions relating to the Company's business, the economy and other future conditions. Forward-looking statements generally can be identified through the use of words such as "believes," "anticipates," "may," "should," "will," "plans," "projects," "expects," "expectations," "estimates," "forecasts," "predicts," "targets," "prospects," "strategy," "signs," and other words of similar meaning in connection with the discussion of future performance, plans, actions or events. Because forward-looking statements relate to the future, they are subject to inherent risks, uncertainties and changes in circumstances that are difficult to predict. Such risks and uncertainties include, among others: (i) the timing to consummate the proposed transaction, (ii) the risk that a condition of closing of the proposed transaction may not be satisfied or that the closing of the proposed transaction might otherwise not occur, (iii) the risk that a regulatory approval that may be required for the proposed transaction is not obtained or is obtained

subject to conditions that are not anticipated, (iv) the diversion of management time on transaction-related issues, (v) risks related to disruption of management time from ongoing business operations due to the proposed transaction, (vi) the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of the common stock of the Company, (vii) the risk that the proposed transaction and its announcement could have an adverse effect on the ability of the Company to retain customers and retain and hire key personnel and maintain relationships with its suppliers and customers, (viii) the occurrence of any event, change or other circumstance or condition that could give rise to the termination of the Merger Agreement, including in circumstances requiring the Company to pay a termination fee, (ix) the risk that competing offers will be made; (x) unexpected costs, charges or expenses resulting from the Merger, (xi) potential litigation relating to the Merger that could be instituted against the parties to the Merger Agreement or their respective directors, managers or officers, including the effects of any outcomes related thereto, (xii) worldwide economic or political changes that affect the markets that the Company's businesses serve which could have an effect on demand for the Company's products and impact the Company's profitability and (xiii) disruptions in the global credit and financial markets, including diminished liquidity and credit availability, changes in international trade agreements, including tariffs and trade restrictions, cyber-security vulnerabilities, foreign currency volatility, swings in consumer confidence and spending, raw material pricing and supply issues, retention of key employees, increases in fuel prices, and outcomes of legal proceedings, claims and investigations. Accordingly, actual results may differ materially from those contemplated by these forward-looking statements. Investors, therefore, are cautioned against relying on any of these forward-looking statements. They are neither statements of historical fact nor guarantees or assurances of future performance. Additional information regarding the factors that may cause actual results to differ materially from these forward-looking statements is available in the Company's filings with the SEC, including the risks and uncertainties identified in Part I, Item 1A - Risk Factors of the Company's Annual Report on Form 10-K for the year ended December 31, 2023 and in the Company's other filings with the SEC.

(b) Subject to the provisions of Article 9, the closing of the Merger (the "Closing") will take place through the electronic exchange of the applicable documents and signature pages at 10:00 a.m. New York City time, using PDFs or electronic signatures, as soon as possible, but in any event no later than four Business Days after the date the conditions set forth in Article 9 (other than conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or, to the extent permissible, waiver of those conditions at the Closing) have been satisfied or, to the extent permissible, waived by the party or parties entitled to the benefit of such conditions, or at such other place, at such other time or on such other date as Parent and the Company may mutually agree in writing. The date on which the Closing actually occurs is referred to herein as the "Closing Date."

(c) At the Closing, the Company and Merger Sub shall file a certificate of merger (the "Certificate of Merger") with the Delaware Secretary of State and make all other filings or recordings required by the DGCL in connection with the Merger. The Merger will become effective at such time as the Certificate of Merger is duly filed with the Delaware Secretary of State (or at such later time as may be specified in the Certificate of Merger) (the "Effective Time").

(d) From and after the Effective Time, the Surviving Corporation will possess all the rights, powers, privileges and franchises and be subject to all of the obligations, liabilities, restrictions and disabilities of the Company and Merger Sub, all as provided under the DGCL.

Section 2.02. Conversion of Shares. At the Effective Time, and by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of any Company Common Shares or any shares of capital stock of Parent or Merger Sub:

(a) Except as otherwise provided in Section 2.02(b) or Section 2.04, each Company Common Share outstanding immediately prior to the Effective Time (including any Company Common Shares to the extent issued in accordance with the terms of this Agreement and the Convertible Notes Indenture) will automatically be converted into the right to receive $113.00 in cash, without interest (the "Merger Consideration"). As of the Effective Time, all such Company Common Shares will no longer be outstanding and will automatically be canceled and retired and will cease to exist, and will thereafter represent only the right to receive the Merger Consideration to be paid in accordance with Section 2.03, without interest.

(b) Each Company Common Share held by the Company as a treasury share or owned by Parent, Merger Sub or any other Subsidiary of Parent immediately prior to the Effective Time will be canceled and cease to exist, and no payment will be made with respect thereto. For the avoidance of doubt, each Company RSU shall be treated in accordance with Section 2.05 hereof.

(c) Each share of common stock of Merger Sub outstanding immediately prior to the Effective Time will be converted into and become one share of common stock of the Surviving Corporation and will constitute the only outstanding shares of capital stock of the Surviving Corporation.

17

Section 2.03. Surrender and Payment. (a) Prior to the Closing Date, Parent shall appoint an agent reasonably acceptable to the Company (the "Exchange Agent") and enter into an exchange agent agreement, reasonably acceptable to the Company, with the Exchange Agent for the purpose of exchanging for the Merger Consideration as promptly as practicable after the Effective Time uncertificated Company Common Shares (the "Shares"). Prior to the Effective Time, Parent shall make available, or cause to be made available, to the Exchange Agent the aggregate Merger Consideration to be paid in respect of the Shares. As promptly as practicable after the Effective Time (but no later than two Business Days thereafter), Parent shall send, or shall cause the Exchange Agent to send, to each holder of Company Common Shares at the Effective Time instructions for use in such exchange.

(b) Each holder of Company Common Shares that have been converted into the right to receive the Merger Consideration will be entitled to receive, upon receipt of an "agent's message" by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request), the Merger Consideration payable for each Share (less any applicable withholding). Until so surrendered or transferred, each such Share will represent from and after the Effective Time for all purposes only the right to receive the Merger Consideration. No interest will be paid or will accrue on the cash payable upon surrender of any such Company Common Shares.

(c) If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name the transferred Share is registered, it will be a condition to such payment that (i) such Share shall be properly transferred and (ii) the Person requesting such payment shall pay to the Exchange Agent any transfer or other Taxes required as a result of such payment to a Person other than the registered holder of such Share or establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(d) At the Effective Time, the share transfer books of the Company will be closed, and there will be no further registration of transfers of Company Common Shares. If, after the Effective Time, Shares are presented to the Surviving Corporation or the Exchange Agent, they will be canceled and exchanged for the Merger Consideration provided for by, and in accordance with the procedures set forth in, this Article 2.

(e) Any portion of the Merger Consideration made available to the Exchange Agent pursuant to Section 2.03(a) (and any interest or other income earned thereon) that remains unclaimed by the holders of Company Common Shares 12 months after the Effective Time will be returned to Parent, upon demand, and any such holder who has not exchanged such Company Common Shares for the Merger Consideration in accordance with this Section 2.03 prior to that time will thereafter look only to Parent for payment of the Merger Consideration in respect of such Company Common Shares without any interest thereon (subject to abandoned property, escheat or similar Applicable Law). Notwithstanding the foregoing, none of Parent, the Surviving Corporation or the Exchange Agent will be liable to any holder of Company Common Shares for Merger Consideration delivered to a Governmental Authority pursuant to any applicable abandoned property, escheat or similar Applicable Law. If any Share shall not have been surrendered as of immediately prior to such date on which any Merger Consideration would otherwise escheat to or become the property of any Governmental Authority, then any such Merger Consideration will, to the extent permitted by Applicable Law, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

18

Section 2.04. Dissenting Shares. (a) Notwithstanding Section 2.02, all Company Common Shares that are issued and outstanding as of immediately prior to the Effective Time and held by a stockholder of the Company who shall have neither voted in favor of the adoption of this Agreement nor consented thereto in writing and who shall have properly and validly demanded their statutory rights of appraisal in respect of such Company Common Shares in accordance with Section 262 of the DGCL (the "Dissenting Company Shares") will not be converted into, or represent the right to receive, the Merger Consideration pursuant to Section 2.02(a). Such Company stockholders will be entitled to receive payment of the appraised value of such Dissenting Company Shares in accordance with the provisions of Section 262 of the DGCL, except that all Dissenting Company Shares held by stockholders of the Company who shall have failed to perfect or who shall have effectively withdrawn or lost their rights to appraisal of such Dissenting Company Shares pursuant to Section 262 of the DGCL will thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without interest thereon, upon surrender or transfer, as applicable, of the Shares that formerly evidenced such Company Common Shares in the manner provided in Section 2.03.

(b) The Company shall give Parent prompt notice and copies of any demands for appraisal received by the Company, withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company in respect of Dissenting Company Shares. Parent shall have the right to participate in, control and direct all negotiations and Proceedings with respect to demands for appraisal pursuant to the DGCL in respect of Dissenting Company Shares. The Company may not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisal or settle or offer to settle any such demands in respect of Dissenting Company Shares.

COVENANTSOF PARENT

Section 7.01. Conduct of Parent. Parent shall not, and shall cause its Affiliates not to, from the date of this Agreement to the Effective Time, take any action that is intended to, or would reasonably be expected to, individually or in the aggregate, prevent, materially delay or materially impede the ability of Parent and Merger Sub to consummate the Merger or the other transactions contemplated by this Agreement, including the financing thereof; provided, however, that this Section 7.01 shall not apply to the matters covered by Section 8.01, which shall be exclusively governed by Section 8.01.

Section 7.02. Obligations of Merger Sub. Parent shall take all action necessary to cause Merger Sub to perform its obligations under this Agreement and to consummate the Merger on the terms and conditions set forth in this Agreement. Immediately following the execution of this Agreement, Parent, as sole stockholder of Merger Sub, shall adopt this Agreement.

Section 7.03. Director and Officer Liability. Parent shall cause the Surviving Corporation, and the Surviving Corporation hereby agrees, to do the following:

(a) For six (6) years after the Effective Time, Parent shall cause (including by providing sufficient funds to) the Surviving Corporation to, indemnify and hold harmless the present and former directors, officers and agents of the Company and its Subsidiaries and any individuals serving in such capacity at or with respect to other Persons at the Company's or its Subsidiaries' request (each, an "Indemnified Person") from and against any losses, damages, liabilities, costs, expenses (including attorneys' fees), judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of any thereof) in respect of the Indemnified Persons' having served in any such capacity prior to the Effective Time, in each case to the fullest extent permitted by the DGCL or any other Applicable Law, in all cases, to the extent provided under the Company's certificate of incorporation and bylaws or other Organizational Documents of the Company or any of its Subsidiaries or any written agreement with such Indemnified Persons, in each case, as in effect on

60

the date hereof and made available to Parent. If any Indemnified Person is made party to any Proceeding arising out of or relating to matters that would be indemnifiable pursuant to the immediately preceding sentence, Parent shall, and shall cause the Surviving Corporation to, advance fees, costs and expenses (including attorneys' fees and disbursements) as incurred by such Indemnified Person in connection with and prior to the final disposition of such Proceeding.

(b) For six years after the Effective Time, Parent shall cause to be maintained in effect provisions in the certificate of incorporation, bylaws or other Organizational Documents of the Surviving Corporation and its Subsidiaries (or in such documents of any successor to the business of the Surviving Corporation or any such Subsidiary) regarding elimination of liability of directors, indemnification of directors, officers and agents, and advancement of fees, costs and expenses that are no less advantageous to the intended beneficiaries than the corresponding provisions in existence on the date of this Agreement.

(c) From and after the Effective Time, Parent shall, and shall cause the Surviving Corporation and its Subsidiaries to, honor and comply with their respective obligations under any indemnification agreement (the form of which is made available to Parent) with any Indemnified Person, and not amend, repeal or otherwise modify any such agreement in any manner that would adversely affect any right of any Indemnified Person thereunder.

(d) Prior to the Effective Time, the Company shall or, if the Company is unable to, Parent shall cause the Surviving Corporation as of the Effective Time to, obtain and fully pay the premium for the noncancelable extension of the directors' and officers' liability coverage of the Company's existing directors' and officers' insurance policies and the Company's existing fiduciary liability insurance policies (collectively, "D&O Insurance"), which D&O Insurance shall (i) be for a claims reporting or discovery period of at least six (6) years from and after the Effective Time with respect to any claim related to any period of time at or prior to the Effective Time, (ii) be from an insurance carrier with the same or better credit rating as the Company's current insurance carrier with respect to D&O Insurance and (iii) have terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under the Company's existing policies (that are made available to Parent) with respect to any actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against an Indemnified Person by reason of his or her having served in such capacity that existed or occurred at or prior to the Effective Time (including in connection with this Agreement or the transactions contemplated by this Agreement, including the Merger). If the Company or the Surviving Corporation for any reason fails to obtain such "tail" insurance policies as of the Effective Time, the Surviving Corporation shall continue to maintain in effect, for a period of at least six (6) years from and after the Effective Time, the D&O Insurance in place as of the date hereof with the Company's current insurance carrier or with an insurance carrier with the same or better credit rating as the Company's current insurance carrier with respect to D&O Insurance with terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under the Company's existing policies as of the date hereof (that are made available to Parent), or the Surviving Corporation shall purchase from the Company's current insurance carrier or from an insurance carrier with the same or better credit rating as the Company's current insurance carrier with respect to D&O Insurance comparable D&O Insurance for such six (6)-year period with terms, conditions, retentions and limits of liability that are no less favorable than as provided in the Company's existing policies as of the date hereof (that are made available to Parent).

61

Notwithstanding the foregoing sentences of this paragraph, in no event shall Parent or the Surviving Corporation be required to (and the Company shall not be permitted to, without Parent's consent) expend for such policies pursuant to this paragraph an aggregate amount in excess of 350% of the premium amount per annum for the Company's director and officer liability insurance policies in effect as of the date of this Agreement; and provided that if the aggregate premiums of such insurance coverage exceed such amount, the Surviving Corporation shall be obligated to obtain a policy with the greatest coverage available, with respect to matters occurring prior to the Effective Time, for a cost not exceeding such amount.

(e) If Parent, the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 7.03.

(f) The rights of each Indemnified Person under this Section 7.03 will be in addition to any rights such Person may have under the certificate of incorporation or bylaws of the Company or any of its Subsidiaries, under the DGCL or any other Applicable Law or under any written agreement of any Indemnified Person with the Company or any of its Subsidiaries (the form of which has been made available to Parent). These rights will survive consummation of the Merger and are intended to benefit, and shall be enforceable by, each Indemnified Person.

Section 7.04. Employee Matters.

(a) For a period commencing at the Effective Time and ending on the date that is 12 months thereafter (or such earlier date that any Continuing Employee terminates employment), Parent shall cause each employee of the Company or its Subsidiaries as of immediately prior to the Effective Time whose employment continues with Parent or one of its Affiliates following the Effective Time (each, a "Continuing Employee") to receive (i) an annual rate of salary or hourly wage rate, as applicable, that is no less favorable than the annual rate of salary or hourly wage rate, as applicable, provided to such Continuing Employee as of immediately prior to the Effective Time (disregarding any increases in such benefits in violation of Section 6.01(m) hereof), (ii) target cash incentive opportunities that are no less favorable in the aggregate than the target cash incentive opportunities provided to such Continuing Employee as of immediately prior to the Effective Time, (iii) severance payments and benefits no less favorable than (x) with respect to U.S.-based Continuing Employees, those described in Section 7.04(a) of the Company Disclosure Schedule (for clarity, Parent may at its option provide severance in accordance with the severance policy applicable to its similarly situated U.S.- based employees to the extent that such severance payments and benefits are no less favorable in the aggregate than those described in Section 7.04(a) of the Company Disclosure Schedule) and (y) with respect to non-U.S.-based Continuing Employees covered by a local severance policy or statutory or regulatory severance or termination benefits, the greater of (1) those payable pursuant to the applicable severance policy disclosed on Section 4.19(a) of the Company Disclosure Schedule and (2) statutory severance or as otherwise required by Applicable Law and (iv) health, welfare and retirement benefits that are substantially comparable in the aggregate to health, welfare

62

and retirement benefits provided, as determined by Parent in its sole discretion, either (x) to such Continuing Employee as of immediately prior to the Effective Time (disregarding any increases in such benefits in violation of Section 6.01(m) hereof) or (y) to similarly situated employees of Parent (including paid time off, but excluding any defined benefit pension, retiree medical or life insurance benefits, equity and equity-based incentives, retention, change in control or similar plans, policies or agreements).

(b) To the extent the short-term incentive bonuses for the performance period in which the Effective Time occurs (or the immediately preceding performance period) remain unpaid as of Closing (whether Closing occurs in such performance period in which the Effective Time occurs or thereafter), Parent shall pay or cause one of its Affiliates to pay bonuses provided for under the Company's short-term performance bonus programs as set forth on Section 7.04(b) of the Company Disclosure Schedule for the performance period in which the Effective Time occurs (or if applicable, the immediately preceding performance period) to each Continuing Employee, with the amount being determined based on actual performance either (A) if the Closing occurs on or before December 31, 2025, through the last day of the applicable performance period (but in no event later than December 31, 2025) or (B) if the Closing occurs after December 31, 2025, through the earlier of (x) the last day of the applicable performance period or (y) the last day of the Surviving Corporation's fiscal year, as such fiscal year may be modified following the Closing, and further subject to and conditioned upon such Continuing Employee satisfying any continued employment and other requirements applicable to such short-term performance bonus program (the "Short-Term Incentives"); provided, that, in the event of an involuntary termination of employment of a Continuing Employee without "cause" by the Surviving Corporation and its Subsidiaries (as applicable) following the Effective Time (as determined by the Surviving Corporation) and prior to the Short-Term Incentives Payment Date (as defined below), the Continuing Employee shall, subject to such Continuing Employee's timely execution of a release of claims in a form prescribed by the Surviving Corporation, be entitled to receive the Short-Term Incentives in accordance with this Section 7.04(b) as if such Continuing Employee had remained employed through the Short-Term Incentives Payment Date, pro-rated to reflect such Continuing Employee's actual tenure during the applicable performance period. The Short-Term Incentives shall be paid by Parent or an Affiliate of Parent (including the Guarantor or the Surviving Corporation) at the time or times that the Short-Term Incentives would normally be paid by the Company, but in all events within sixty (60) days following the end of the applicable period relating to the Short-Term Incentives in accordance with all terms and conditions applicable to such Short-Term Incentives (the "Short-Term Incentives Payment Date").

(c) Parent shall cause the Surviving Corporation and any of its respective Subsidiaries (and any of their respective third-party insurance providers or third-party administrators) to use commercially reasonable efforts to (i) waive all limitations as to any pre-existing condition or waiting periods with respect to participation and coverage requirements applicable to each Continuing Employee under any employee benefit plan maintained by Parent and its Affiliates in which such Continuing Employees become eligible to participate as of or after the Effective Time (the "Parent Plans"), to the extent pre-existing conditions and waiting periods did not apply or were satisfied under a similar Company Plan prior to the Effective Time, and (ii) credit each Continuing Employee, as of and after the Effective Time, for any copayments, deductibles, offsets or similar payments made during the plan year that includes the Effective Time for purposes of satisfying any applicable copayment, deductible, offset or similar requirements under the

63

comparable Parent Plan (to the extent such credit would have been given under comparable Company Plans prior to the Closing). In addition, as of the Effective Time, Parent shall cause the Surviving Corporation and any applicable Subsidiary to give all Continuing Employees full credit for such Continuing Employees' service with the Company or any of its Subsidiaries for purposes of eligibility, vesting and accruals under any Parent Plans in which any Continuing Employee becomes eligible to participate after the Effective Time, to the same extent and for the same purpose that such service was credited for under any similar Company Plan immediately prior to the Effective Time, provided that such credit for service shall not apply to the extent it would result in a duplication of benefits or compensation or with respect to the vesting of incentive awards that vest based on service following grant.

(d) Without limiting the generality of Section 11.06, the provisions of this Section 7.04 are solely for the benefit of the parties to this Agreement, and no Company Service Provider or any other individual associated therewith (including any beneficiaries or dependents thereof) shall be regarded for any purpose as a third-party beneficiary of this Section 7.04. Nothing herein shall, or be deemed to (i) establish, terminate, amend or modify any Company Plan, Parent Plan or any other compensation or benefit plan, program, policy, agreement or arrangement; (ii) alter or limit Parent's, Merger Sub's or any of their respective Affiliates' (including the Surviving Corporation's) ability to establish, terminate, amend or modify any particular benefit plan, program, policy, agreement or arrangement or (iii) prevent or restrict in any way the right of the Parent to terminate, reassign, promote or demote any Company Service Provider (or to cause any of the foregoing actions) at any time following the Closing, confer upon any Company Service Provider any right to employment or continued employment for any period of time by reason of this Agreement, or to change (or cause the change of) the title, powers, duties, responsibilities, functions, locations, salaries, other compensation or terms or conditions of employment or service of any such Company Service Providers at any time following the Closing.

Section 8.04. Public Announcements. Each party hereto shall issue its own initial press release relating to this Agreement, each in a form and substance reasonably agreed to by the other party, and the text of which shall have been provided to the other party at least one (1) Business Day prior to such issuance. Thereafter, except in connection with the matters contemplated by Section 6.04 or in connection with any dispute between the parties regarding this Agreement, the Merger or the other transactions contemplated hereby, Parent and the Company (a) shall consult with each other before issuing any further press release, having any communication with the press (whether or not for attribution) or making any other public statement (including any announcement to officers or employees of the Company or its Subsidiaries), or scheduling any press conference or conference call with investors or analysts, with respect to this Agreement or the transactions contemplated hereby, (other than any press release, communication, public statement, press conference or conference call which has a bona fide purpose that does not relate to this Agreement or the transactions contemplated hereby, and in which this Agreement and the transactions contemplated hereby are mentioned only incidentally and in a manner consistent with previous press releases, public disclosures or public statements made jointly by the parties (or individually, if approved by the other party)) and (b) except in respect of any public statement or press release as may be required by Applicable Law or any listing agreement with or rule of any national securities exchange or association (provided, in such case, such party has given advance notice (and an opportunity to review and comment to the extent practicable) to the other party), shall not

issue any such press release or make any such other public statement or schedule any such press conference or conference call before obtaining the other party's written consent (which consent shall not be unreasonably withheld, delayed or conditioned). Notwithstanding the foregoing, after the issuance of the initial press releases or any press release or the making of any public statement with respect to which the foregoing procedures and other terms have been followed and complied with, either party may issue such additional publications or press releases and make such other customary announcements and public statements without consulting with any other party hereto so long as such additional publications, press releases, announcements and public statements do not disclose any nonpublic information regarding the transactions contemplated by this Agreement beyond the scope of the disclosure included in, and materially consistent with, the initial press release or such other press release or public statement with respect to which the other party had consented (or been consulted) in accordance with the terms of this Section 8.04.

Section 8.05. Convertible Notes.

(a) On the Closing Date, Parent, Merger Sub and the Company shall, as and to the extent required by the Convertible Notes Indenture, execute, and use reasonable best efforts to cause the Trustee to execute, any supplemental indenture required by the Convertible Notes Indenture and deliver any certificates and other documents required by the Convertible Notes Indenture to be delivered by such Persons in connection with such supplemental indenture. Notwithstanding anything to the contrary in this Agreement and subject to the immediately preceding sentence, prior to the Effective Time, the Company shall give any notices and take all actions required under, and with the prior consent of Parent, not to be unreasonably withheld, conditioned or delayed, may take actions permitted under, the terms of the Convertible Notes, the Convertible Notes Indenture or under Applicable Law, and shall take any other actions reasonably requested by Parent to the extent such actions are permitted or contemplated by, the terms of the Convertible Notes Indenture, the Convertible Notes or any Applicable Law (with respect to the Convertible Notes Indenture or the Convertible Notes) in connection with the Merger and the other transactions contemplated by this Agreement, which actions shall include the Company (or its Subsidiaries or other Representatives, as applicable) (i) giving any notices that may be required in connection with the Merger and the other transactions contemplated by this Agreement and making any repurchases or conversions of the Convertible Notes occurring prior to or as a result of the Merger, (ii) preparing any supplemental indentures required in connection with the Merger and the other transactions contemplated by this Agreement and the consummation thereof to be executed and delivered to the Trustee at or prior to the Effective Time, in form and substance reasonably satisfactory to the Trustee and Parent, and (iii) taking all such further actions, including delivering any officer's certificates and legal opinions, as may be necessary to comply with all of the terms and conditions of the Convertible Notes Indenture in connection with the Merger and the other transactions contemplated by this Agreement. Notwithstanding anything to the contrary in this Agreement, prior to the Effective Time, the Company may settle conversions of the Convertible Notes pursuant to the terms of the Convertible Notes Indenture. For the avoidance of doubt, the transactions contemplated by this Agreement shall be deemed to include effecting any conversions under the terms of the Convertible Notes and the Convertible Notes Indenture. Notwithstanding anything to the contrary in this Section 8.05, but subject to the terms of the Convertible Notes Indenture, nothing herein shall require the Company to make any payment with respect to the Convertible Notes in connection with the Merger (including in connection with the settlement of any conversion obligations), prior to the occurrence of the Effective Time.

69

(b) The Company shall use its reasonable best efforts to provide Parent and its counsel reasonable opportunity to review and comment on any notices, certificates, press releases, supplemental indentures or other documents or instruments deliverable pursuant to the Convertible Notes Indenture prior to the dispatch or making thereof and shall incorporate all reasonable comments provided by Parent and its counsel with respect thereto.

(c) Notwithstanding anything in this Agreement to the contrary, it is understood and agreed that nothing in this Section 8.05 shall require the Company to (i) pay any fees, incur or reimburse any costs or expenses, or make any payment prior to the occurrence of the Effective Time for which it has not first received full reimbursement or is not otherwise indemnified or subject to reimbursement under this Agreement; (ii) enter into any instrument or agreement, or agree to any change, adjustment, waiver or modification to or termination or unwind of any instrument or agreement, that is effective prior to the occurrence of the Effective Time or that would be effective if the Effective Time did not occur; or (iii) provide access to or disclose information that would reasonably be expected to jeopardize attorney-client privilege or any other privilege (provided that the Company shall use its reasonable best efforts to allow for such access or disclosure in a manner that does not result in a loss of such privilege) or contravene Applicable Law or violate any contract to which the Company or any of its Subsidiaries is party and entered into prior to the date of this Agreement. For the avoidance of doubt, and without limiting the obligations in this Section 8.05, each of Parent and Merger Sub acknowledges and agrees that its obligations to consummate the transactions contemplated by this Agreement are not conditioned upon either the execution of any supplemental indenture pursuant to the Convertible Notes Indenture by the Trustee.

Section 8.06. Further Assurances. At and after the Effective Time, the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of the Company or Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Company or Merger Sub, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets of the Company acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger.

Section 8.07. Section 16 Matters. Prior to the Effective Time, the Company shall take all such steps as may be required to cause any dispositions of Company Common Shares in connection with the transactions contemplated by this Agreement (including derivative securities of such Company Common Shares) by each individual who is subject to the reporting requirements of Section 16(a) of the 1934 Act with respect to the Company to be exempt under Rule 16b-3 promulgated under the 1934 Act.

Section 8.08. Notices of Certain Events. Each of the Company and Parent shall promptly notify the other of any of the following: (a) any written notice or other written communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement; (b) any written notice or other written communication from any Governmental Authority in connection with the transactions contemplated by this Agreement (other than such notices or communications contemplated by Section 8.01, which shall be governed by such Section); and (c) any Proceedings commenced or,

70

to its Knowledge, threatened in writing against, relating to or involving or otherwise affecting the Company or any of its Subsidiaries or Parent or any of its Subsidiaries, as the case may be, that relate to the consummation of the transactions contemplated by this Agreement; provided that a party's good-faith failure to comply with this Section 8.08 shall not constitute a breach of this Section 8.08, and shall not provide any other party the right not to effect, or the right to terminate, the transactions contemplated by this Agreement, except to the extent that any other provision of this Agreement independently provides such right.

Section 8.09. Litigation and Proceedings. Prior to the earlier of the Effective Time or the valid termination of this Agreement, the Company shall control the defense or settlement of any litigation or other Proceedings (except for (x) Proceedings related to Competition Laws, which shall be governed by Section 8.01(b), Section 8.01(c) and Section 8.01(d) and (y) Proceedings in connection with or arising out of or otherwise related a demand for dissenters' rights under Applicable Law, which shall be governed by Section 2.04(b)) against the Company or any of its directors or officers relating to this Agreement, the Merger or the other transactions contemplated by this Agreement ("Transaction Litigation"); provided that, other than Proceedings between or among the parties hereto or their Affiliates, the Company shall (a) give Parent prompt written notice of any Transaction Litigation, including by providing copies of all pleadings with respect thereto, (b) give Parent a reasonable opportunity to participate, at Parent's expense, in the defense, settlement or prosecution of any Transaction Litigation and (c) consult with Parent with respect to the defense, settlement and prosecution of any Transaction Litigation; and provided, further, that, other than Proceedings between or among the parties hereto or their Affiliates, the Company agrees that it shall not settle or offer to settle any Transaction Litigation without the prior written consent of Parent, which shall not be unreasonably withheld, delayed or conditioned. For purposes of this Section 8.09, "participate" means that Parent will be kept reasonably apprised of significant decisions with respect to the Transaction Litigation by the Company, and Parent may offer comments or suggestions with respect to such Transaction Litigation (which the Company shall consider in good faith), but will not be afforded any decision-making power or other authority over such Transaction Litigation except for the right to consent to any settlement as set forth in the preceding sentence.

Section 8.10. Takeover Statutes. If any "control share acquisition," "fair price," "moratorium," "business combination" or other similar antitakeover statute or regulation, including any Takeover Statute, shall become applicable to the transactions contemplated by this Agreement, each of the Company, Parent and Merger Sub and the respective members of their boards of directors shall, to the extent permitted by Applicable Law, use reasonable best efforts to grant such approvals and to 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 herein and otherwise to take all such other actions as are reasonably necessary to eliminate or minimize the effects of any such statute or regulation on the transactions contemplated hereby.

Section 8.11. FIRPTA Certificate and Notice. Prior to the Closing, (a) Parent shall provide a draft of a statement and accompanying Internal Revenue Service notice, to be issued pursuant to Treasury Regulations Sections 1.897-2(h) and 1.1445-2(c)(3)(i), certifying that the stock of the Company is not a United States real property interest within the meaning of Section 897 of the Code and (b) the Company shall deliver to Parent an executed version of such statement

71

and notice, in form and substance reasonably satisfactory to Parent. The failure to deliver an executed version of such statement and notice shall not constitute a breach of a covenant, obligation or agreement of the Company for purposes of Section 9.02(a)(i) and the sole remedy of Parent for such failure to deliver shall be withholding under Section 2.07.

(ii) there shall be any (x) Applicable Law (other than, solely for the purposes of this Section 10.01(b)(ii), a Competition Law that does not relate to a Required Regulatory Approval), or (y) final, irreversible and non-appealable Order (provided that, if such Order is issued by any Governmental Authorities pursuant to Competition Laws, such Order relates to the Required Regulatory Approvals) issued, entered, promulgated or enacted by any Governmental Authority of competent jurisdiction, in either case, permanently prohibiting, permanently rendering illegal or permanently enjoining the consummation of the Merger; or

(iii) at the Company Stockholders Meeting (including any adjournment or postponement thereof), which shall have been duly convened and at which a vote on the adoption of this Agreement has been taken, the Company Stockholder Approval shall not have been obtained; or

(i) prior to receipt of the Company Stockholder Approval, an Adverse Recommendation Change shall have occurred; or

74

(ii) a breach of any representation or warranty or failure to perform any covenant or agreement on the part of the Company set forth in this Agreement shall have occurred that (A) would cause any of the conditions set forth in Section 9.02(a)(i)-(vi) not to be satisfied and (B) is incapable of being cured or, if curable, has not been cured by the date that is 20 Business Days after the Company's receipt of written notice thereof from Parent (or, if earlier, five Business Days prior to the End Date or the Extended End Date, as applicable); provided that the right to terminate this Agreement pursuant to this Section 10.01(c)(ii) shall not be available if Parent or Merger Sub is in breach of any provision of this Agreement or has failed to perform or comply with, or if there is any inaccuracy of, any of its representations, warranties, covenants or agreements set forth in this Agreement, and which breach, failure or inaccuracy caused or resulted, or would cause or result, in the failure of any of the conditions set forth in Section 9.03(a) to be satisfied; or

(ii) a breach of any representation or warranty or failure to perform any covenant or agreement on the part of Parent or Merger Sub set forth in this Agreement shall have occurred (A) that would cause the conditions set forth in Section 9.03(a)(i), Section 9.03(a)(ii) or Section 9.03(a)(iii) not to be satisfied and (B) that is incapable of being cured or, if curable, has not been cured by the date that is 20 Business Days after its receipt of written notice thereof from the Company (or, if earlier, five Business Days prior to the End Date or the Extended End Date, as applicable); provided that the right to terminate this Agreement pursuant to this Section 10.01(d)(ii) shall not be available if the Company is in breach of any provision of this Agreement or has failed to perform or comply with, or if there is any inaccuracy of, any of its representations, warranties, covenants or agreements set forth in this Agreement, and which breach, failure or inaccuracy caused or resulted, or would cause or result, in the failure of any of the conditions set forth in Section 9.02(a) to be satisfied.

The party desiring to terminate this Agreement pursuant to this Section 10.01 (other than pursuant to Section 10.01(a)) shall give notice of such termination to the other parties specifying the provision of Section 10.01 pursuant to which this Agreement is being terminated.

Section 10.02. Effect of Termination. If this Agreement is terminated pursuant to Section 10.01, subject to Section 10.03, this Agreement shall become void and of no effect without liability of any party to the other parties hereto (or any stockholder, director, officer, employee, agent, consultant or representative of such party); provided that, subject to Section 10.03 in all respects, if such termination shall result from (a) the intentional failure of any party to fulfill a condition to the performance of the obligations of any other party or (b) the intentional breach of this Agreement by any party, such party shall be fully liable for any and all liabilities and damages

75

(which the parties acknowledge and agree will not be limited to reimbursement of expenses or out-of-pocket costs, and may include, the benefit of the bargain lost by a party's stockholders (including, (x) in the case of the Company, the premium reflected in the Merger Consideration, which was specifically negotiated by the Board of Directors on behalf of the Company's shareholders and (y) in the case of Parent, the benefit that Parent and its Affiliates would have derived from the consummation of the Merger, including expected integration synergies, which was specifically negotiated by Parent, in each case, taking into consideration all other relevant matters), which will be deemed in such event to be damages of such party as determined by the trier of fact) incurred or suffered by the other parties as a result of such failure or breach. The Confidentiality Agreements and the provisions of Section 6.03(b), Section 8.04, this Section 10.02, Section 10.03 and Article 11 shall survive any termination hereof pursuant to Section 10.01.

Section 10.03. Termination Fees.

(a) In the event that (i) this Agreement is terminated by either the Company or Parent pursuant to Section 10.01(b)(i) (End Date) or Section 10.01(b)(ii) (Permanent Order) and (ii) at the time of such termination, all of the conditions set forth in Section 9.01 and Section 9.02 have been satisfied or waived (other than any of (x) the conditions set forth in Section 9.01(b) (solely as they relate to Competition Laws or Orders issued, entered, promulgated or enacted by any Governmental Authority pursuant to any Competition Law) or Section 9.01(c) or (y) those other conditions that, by their nature, cannot be satisfied until the Closing but, in the case of this clause (y), are capable of being satisfied, and (other than the condition set forth in Section 9.02(a)(vii)) would be satisfied, at the Closing if the Closing were to occur at the time of such termination), then Parent shall pay or cause to be paid to the Company in immediately available funds $638,000,000 (the "Parent Termination Fee"), in each case, in the case of a termination by the Company, within two (2) Business Days after such termination and, in the case of a termination by Parent, immediately before and as a condition to such termination. In no event shall Parent be required to pay the Parent Termination Fee on more than one occasion.

(b) (i) If this Agreement is terminated by the Company pursuant to Section 10.01(d)(i) (Superior Proposal) or by Parent pursuant to Section 10.01(c)(i) (Adverse Recommendation Change), then the Company shall pay or cause to be paid to Parent in immediately available funds $372,000,000 (in each case, such fee, the "Company Termination Fee"), in the case of a termination by Parent, within two (2) Business Days after such termination and, in the case of a termination by the Company, immediately before and as a condition to such termination.

(ii) If, prior to receipt of the Company Stockholder Approval, (A) this Agreement is terminated (x) by Parent or the Company pursuant to Section 10.01(b)(i) (End Date) or Section 10.01(b)(iii) (Company No Vote) or (y) by Parent pursuant to Section 10.01(c)(ii) (Company Breach), (B) after the date of this Agreement and prior to the Company Stockholders Meeting, an Acquisition Proposal shall have been publicly announced (or, solely in the case of a termination pursuant to Section 10.01(c)(ii) (Company Breach), made to the Board of Directors) and not withdrawn prior to the date of the Company Stockholders Meeting (in the case of a termination pursuant to Section 10.01(b)(iii) (Company No Vote)) and (C) within 12 months after the date of such termination, the Company or any of its Subsidiaries enters into a definitive written agreement with respect to such Acquisition Proposal or a transaction with respect to such

76

Acquisition Proposal shall have been consummated (provided that for purposes of this Section 10.03(b)(ii), each reference to "20%" in the definition of Acquisition Proposal shall be deemed to be a reference to "50%"), then the Company shall pay to Parent in immediately available funds, concurrently with the entry into a definitive written agreement with respect to such Acquisition Proposal, the Company Termination Fee.

(iii) In no event shall the Company be required to pay the Company Termination Fee on more than one occasion.

(c) Each party agrees that (i) the agreements contained in this Section 10.03 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, the other parties would not enter into this Agreement and (ii) in light of the difficulty of accurately determining actual damages with respect to the foregoing, the right to payment of the Parent Termination Fee or the Company Termination Fee, as applicable, constitutes a reasonable estimate of the losses, damages, claims, costs or expenses that will be suffered by reason of any such termination of this Agreement and constitutes liquidated damages (and not a penalty) and hereby irrevocably waives, and agrees not to assert in any Proceeding arising out of or relating to this Agreement, any claim to the contrary. Each party further acknowledges that neither the Parent Termination Fee nor the Company Termination Fee, if, as and when paid in accordance with the terms of this Section 10.03, is a penalty, but each is instead liquidated damages in a reasonable amount that will compensate the recipient thereof in circumstances in which such fee is payable for the efforts and resources expended, and opportunities forgone, while negotiating this Agreement, and for such recipient's reliance on this Agreement, and on the expectation of the consummation of the transactions contemplated hereby, which amounts would otherwise be impossible to calculate with precision.

(d) If the Company fails to pay the Company Termination Fee or the Parent fails to pay the Parent Termination Fee, as applicable, when due pursuant to this Section 10.03, the party that has failed to pay the Company Termination Fee or the Parent Termination Fee, as applicable, shall pay to the other party an amount equal to such other party's reasonable and documented out-of-pocket costs and expenses (including reasonable fees and disbursements of counsel) incurred in connection with seeking payment of the Company Termination Fee from the Company or the Parent Termination Fee from Parent (including with respect to any such Proceeding commenced by the applicable party hereto or any of its Affiliates), together with interest on the amount of the Company Termination Fee or the Parent Termination Fee, as applicable, at an interest rate per annum equal to the prime rate in effect on the date hereof (as published in the Wall Street Journal, Eastern Edition), plus seven percent (7%), from the date the payment of the Company Termination Fee or the Parent Termination Fee, as applicable, is due through the date such payment is actually received in full by the other party (any amounts due pursuant to this Section 10.03(d), the "Expenses").

(e) Notwithstanding anything herein to the contrary, Parent and Merger Sub agree that, upon any termination of this Agreement under circumstances where the Company Termination Fee is payable by the Company pursuant to Section 10.03(b) and such Company Termination Fee (together with any Expenses, if payable) is paid in full, such Company Termination Fee (together with any Expenses, if payable) shall be the sole and exclusive remedy of the Parent and Merger Sub in connection with this Agreement or the transactions contemplated hereby, including the

77

Merger, and neither Parent nor Merger Sub shall seek to obtain any recovery, judgment, or damages of any kind, including consequential, indirect, or punitive damages, against the Company or any of the Company's Subsidiaries or any of their respective directors, officers, employees, partners, managers, members, stockholders, Affiliates or Representatives in connection with this Agreement or the transactions contemplated hereby, including any breach of this Agreement (including any willful or intentional and knowing breach) or the termination hereof.

(f) Notwithstanding anything herein to the contrary, the Company agrees that, upon any termination of this Agreement under circumstances where the Parent Termination Fee is payable by Parent pursuant to Section 10.03(a) and such Parent Termination Fee (together with any Expenses, if payable) is paid in full, such Parent Termination Fee (together with any Expenses, if payable) shall be the sole and exclusive remedy of the Company in connection with this Agreement or the transactions contemplated hereby, including the Merger, and the Company shall not seek to obtain any recovery, judgment, or damages of any kind, including consequential, indirect, or punitive damages, against Parent or Merger Sub or any of their respective Affiliates (including the Guarantor) or any of their respective directors, officers, employees, partners, managers, members, stockholders, Affiliates or Representatives in connection with this Agreement or the transactions contemplated hereby, including any breach of this Agreement (including any willful or intentional and knowing breach) or the termination hereof.

Section 11.03. Amendments and Waivers. (a) Any provision of this Agreement may be amended or waived prior to the Effective Time if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement or, in the case of a waiver, by each party against whom the waiver is to be effective; provided that, after the Company Stockholder Approval has been obtained, there shall be no amendment or waiver that would require the further approval of the stockholders of the Company under the DGCL or in accordance with the rules of any relevant stock exchange without such approval having first been obtained.

Process in any such Proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 11.01 shall be deemed effective service of process on such party.

Section 11.09. WAIVER OF JURY TRIAL.

Section 11.10. Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Counterparts may be delivered via electronic mail (including .pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000 (e.g., www.docusign.com)) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective as delivery of a manually executed counterpart of this Agreement. Each of the parties hereto represents that it has undertaken commercially reasonable steps to verify the identity of each individual person executing any such counterparts via electronic signature on behalf of such party and has and will maintain sufficient records of the same. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by all of the other parties hereto. Until and unless each party has received a counterpart hereof signed by each other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

Section 11.11. Entire Agreement. This Agreement, the Voting Agreement, the Support Agreement and the Confidentiality Agreements constitute the entire agreement between the parties with respect to the subject matter of this Agreement and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter of this Agreement.

Section 11.12. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 11.13. Specific Performance. The parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with its terms, and that monetary damages, even if available, would not be an adequate remedy therefor. Accordingly, the parties hereto agree that the parties shall be entitled to an injunction or injunctions, or any other appropriate form of equitable relief, to prevent or restrain breaches or threatened breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof, without the necessity of proving that irreparable damage would occur or the

82

inadequacy of money damages as a remedy (and each party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), in addition to any other remedy to which they are entitled at law or in equity. The parties hereto hereby waive any defense, and agree not to assert (or interpose as a defense or in opposition), that a remedy of specific performance or other equitable relief is unenforceable, invalid, contrary to law or inequitable for any reason, that a remedy of monetary damages (including any fee payable pursuant to Section 10.03) would provide an adequate remedy or that the parties otherwise have an adequate remedy at law. Notwithstanding anything herein to the contrary, if, prior to the End Date or the Extended End Date, as applicable, any party brings any Proceeding to enforce specifically the performance of the terms and provisions hereof by any other party, the End Date or the Extended End Date, as applicable, shall automatically be extended by the amount of time during which such Proceeding is pending, plus five Business Days, or such longer time period established by the court presiding over such Proceeding, if any.

Each Stockholder agrees to promptly notify Parent and the Company of any required corrections with respect to any information supplied by or on behalf of such Stockholder specifically for use in any such disclosure document, if and to the extent that any such information shall contain any untrue statement of material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading.

Section 4.04 Adjustments. In the event of any stock split, stock dividend or distribution, reorganization, recapitalization, readjustment, reclassification, combination, exchange of shares or the like of the capital stock of the Company on, of or affecting any Subject Shares, then the terms of this Agreement shall apply to the Company Securities and Company Subsidiary Securities received in respect of such Subject Shares by such Stockholder immediately following the effectiveness of the events described in this Section 4.04, as though they were Subject Shares hereunder.

Section 4.05 Non-Solicitation.

To the attention of

Mr. James R. Scapa, Chairman of the Board and Chief Executive Officer

This DEED is dated October 30, 2024

Parent Company Guarantee Deed

The parties agree hereby agree as follows:

Siemens AG ("Siemens Parent") is the ultimate parent of Siemens Industry Software Inc. ("Siemens Industry Software"). Siemens Parent takes notice of the Merger Agreement to be signed by and among Siemens Industry Software, Astra Merger Sub Inc. ("Merger Subsidiary") and Altair Engineering Inc. ("Company") on the date hereof (as may be amended or modified from time to time in accordance with its terms, the "Merger Agreement"). As an inducement for Company to enter into the Merger Agreement, Siemens Parent is entering into this deed (the "Parent Company Guarantee"), in respect of which Company has provided good and valid consideration to Siemens Parent in the amount of one euro (€1.00), receipt of which is hereby acknowledged by Siemens Parent. All capitalized terms used and not defined herein shall have the same respective meanings as ascribed to them in the Merger Agreement.

In accordance with the foregoing, and upon the terms and subject to the conditions set forth herein, Siemens Parent hereby irrevocably and unconditionally guarantees to Company the full, complete and punctual discharge and performance of all of Siemens Industry Software's (a) payment obligations under the Merger Agreement, including (i) the Parent Termination Fee and the Expenses, (ii) the Merger Consideration, (iii) the fees, costs and expenses specified in Section 8.01(e) of the Merger Agreement and (iv) any amounts payable by Siemens Industry Software pursuant to Section 10.02 of the Merger Agreement (clauses (i)-(iv), collectively, the "Payment Obligations") as if it were the principal obligor in respect of those amounts and (b) obligations set forth in Sections 8.01 of the Merger Agreement (the "Regulatory Covenants") (the obligations in this clause (b), the "Parent Obligations", and together with the Payment Obligations, the "Guaranteed Obligations"), and irrevocably and unconditionally agrees to (and to cause its Affiliates to) comply in all respects with the Regulatory Covenants that are applicable to Affiliates of Siemens Industry Software as if they were a party thereto, all in accordance with, and subject to, the terms and conditions of the Merger Agreement.

If Siemens Industry Software fails to pay or perform all or any portion of the Guaranteed Obligations if, as and when they become due under the Merger Agreement, Siemens Parent's liability to the Company hereunder in respect of the applicable Guaranteed Obligations shall, at Company's option, become immediately due and (in the case of the Payment Obligations) payable, to the extent provided herein, and the Company may at any time and from time to time take any and all actions available hereunder or under Applicable Law to collect the Payment Obligations from Siemens Parent (as if it were the principal obligor in respect of those amounts), and enforce the Parent Obligations against Siemens Parent. Company agrees that Siemens Parent shall be entitled to satisfy the Guaranteed Obligations through any of its Affiliates and on behalf of Siemens Industry Software, rather than directly through Siemens Parent, in its own discretion.

Page 1 of 7

This Parent Company Guarantee is a continuing guaranty of the Guaranteed Obligations, and is a guaranty of payment and, solely with respect to (and to the extent of) the Parent Obligations, of performance, and not of collectability. Separate Proceedings may be brought and prosecuted against Siemens Parent to enforce this Parent Company Guarantee, irrespective of whether any Proceeding is brought against Siemens Industry Software or whether Siemens Industry Software is joined in any such Proceeding. The liability of Siemens Parent under this Parent Company Guarantee shall be irrevocable and unconditional, and shall not be reduced, discharged or otherwise adversely affected by: (a) any variation, extension, discharge, compromise, dealing with, exchange or renewal of any right or remedy which Company may now or after the date of this Parent Company Guarantee have from or against any of Siemens Industry Software and any other person in connection with the Guaranteed Obligations; (b) any act or omission by Company or any other person in taking up, perfecting or enforcing any security, indemnity or guarantee from or against Siemens Industry Software or any other Person; (c) any amendment, variation or novation of or to any of the Guaranteed Obligations; (d) any grant of time, indulgence, waiver or concession to Siemens Industry Software or any other Person; (e) any insolvency, bankruptcy, liquidation, administration, winding up, incapacity, limitation, disability or any change in the constitution, name or style of Siemens Industry Software or any other Person; (f) any invalidity, illegality, unenforceability, irregularity or frustration of any actual or purported obligation of, or security held from, Siemens Industry Software or any other Person in connection with the Guaranteed Obligations; (g) any claim of payment from Siemens Industry Software or any other Person; (h) any act or omission which would not have discharged or affected the liability of Siemens Parent had it been a principal debtor instead of a guarantor under the Merger Agreement; (i) any change in the corporate existence, structure or ownership of Siemens Parent, Siemens Industry Software or Merger Subsidiary, or any insolvency, bankruptcy, reorganization, moratorium or other similar proceeding affecting Siemens Parent, Siemens Industry Software or Merger Subsidiary; (j) any waiver, amendment or modification of the Merger Agreement, except to the extent such waiver, amendment or modification of the Merger Agreement, which is entered in writing by Siemens Industry Software and the Company, reduces, limits or otherwise decreases the Guaranteed Obligations, in which case the liability of Siemens Parent under this Parent Company Guarantee shall be reduced accordingly; or (k) the adequacy of any other means Company may have of obtaining payment of any of the Guaranteed Obligations.

Siemens Parent hereby irrevocably waives any and all notice of the creation, renewal, extension or accrual of any of the Guaranteed Obligations and notice of or proof of reliance by the Company upon this Parent Company Guarantee or acceptance of this Parent Company Guarantee. Siemens Parent acknowledges that it will receive substantial indirect benefits from the transactions contemplated by the Merger Agreement and that the waivers set forth in this Parent Company Guarantee are knowingly made in contemplation of such benefits. The Guaranteed Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon this Parent Company Guarantee, and all dealings between Siemens Industry Software, Merger Subsidiary or Siemens Parent, on the one hand, and the Company, on the other hand, shall likewise be conclusively presumed to have been had or consummated in reliance upon this Parent Company Guarantee. When pursuing its rights

Page 2 of 7

and remedies hereunder against Siemens Parent, the Company shall be under no obligation to pursue any right of offset with respect thereto, and any failure by the Company to pursue any rights or remedies or to collect any payments from Siemens Industry Software, Merger Subsidiary or any such other Person or to realize upon or to exercise any such right of offset shall not relieve the Guarantors of any liability hereunder.

Company shall not be obliged, before taking steps to enforce any of its rights and remedies under this Parent Company Guarantee, to make or file any claim in a bankruptcy, liquidation, administration or insolvency of Siemens Industry Software or any other Person, and the failure of the Company to so file such claim shall not affect Siemens Parent's obligations hereunder (and notwithstanding anything herein to the contrary, any bar to the payment, or collection, of any Guaranteed Obligations as a result of any such Proceeding shall not discharge the obligations of Siemens Parent hereunder).

Altair Signs Definitive Agreement with Siemens to be Acquired for $10.6 Billion

Altair Stockholders to Receive $113 Per Share in Cash

TROY, Mich., Oct. 30, 2024 /PRNewswire/ - Altair (Nasdaq: ALTR), a global leader in computational intelligence, today announced that it has entered into a definitive agreement to be acquired by Siemens, a leading technology company focused on industry, infrastructure, mobility, and healthcare. Altair stockholders will receive $113.00 per share in cash, representing an equity value of approximately $10.6 billion. The $113.00 per share cash consideration represents a 19% premium to the closing price of Altair common stock on October 21, 2024, the last trading day prior to media speculation regarding a potential transaction, and a 13% premium to Altair's unaffected all-time high closing price.

"This acquisition represents the culmination of nearly 40 years in which Altair has grown from a startup in Detroit to a world-class software and technology company. We have added thousands of customers globally in manufacturing, life sciences, energy and financial services, and built an amazing workforce, and innovative culture," said James Scapa, Altair's founder and CEO. "We believe this combination of two strongly complementary leaders in the engineering software space brings together Altair's broad portfolio in simulation, data science, and HPC with Siemens' strong position in mechanical and EDA design. Siemens' outstanding technology, strategic customer relationships, and honest, technical culture is an excellent fit for Altair to continue its journey driving innovation with computational intelligence."

"Acquiring Altair marks a significant milestone for Siemens. This strategic investment aligns with our commitment to accelerate the digital and sustainability transformations of our customers by combining the real and digital worlds. The addition of Altair's capabilities in simulation, high performance computing, data science, and artificial intelligence together with Siemens Xcelerator will create the world's most complete AI-powered design and simulation portfolio," said Roland Busch, President and CEO of Siemens AG. "It is a logical next step: we have been building our leadership in industrial software for the last 15 years, most recently, democratizing the benefits of data and AI for entire industries."

Approvals and Timing

The transaction, which was unanimously approved by the Altair Board of Directors, is expected to close in the second half of 2025, following the receipt of regulatory approvals, Altair stockholder approval and the satisfaction of customary closing conditions. Upon completion of the transaction, Altair's common stock will no longer be listed on any public stock exchange.
