WHEREAS, the Investor acknowledges that the Company is exploring and may enter into other definitive agreements with other Accredited Investors (as defined below) not affiliated with the Investor or the Company that are selected by the Company (each, an “Other Investor”) (each such definitive agreement, an “Other Investment Agreement”) providing for one or more acquisitions of up to an aggregate amount of 33,333,334 Common Units by Other Investors (such transaction or transactions, each, an “Other Investment” and, collectively, “Other Investments”);

WHEREAS, it is proposed that prior to the Closing, the Company will effectuate the separation of the SiC Business in accordance with the separation principles set forth in Exhibit B (the “Separation Principles”); and

The date, time and place of the closing of the purchase and sale of the Purchased Units provided for in this Agreement (the “Closing”) will take place at 10:00 a.m., Eastern time, on the latest of (a) the sixth (6th) Business Day following the satisfaction or, to the extent permitted by applicable Law, waiver of the last condition in Article V to be satisfied or waived (other than those conditions that by their

nature are to be satisfied at the Closing, but subject to the fulfillment or, to the extent permitted by applicable Law, waiver of those conditions), either remotely via the electronic exchange of documents and signatures (or their electronic counterparts) or (b) at such other time and place as the Investor and the Company mutually agree (the “Closing Date”); provided, however, that notwithstanding the foregoing, the Closing shall not occur prior to the third (3^rd) Business Day following the expiration of the Post-CFIUS Briefing Period.

(a) Upon the terms and subject to the conditions set forth in this Agreement, at the Closing, the Company shall issue and sell to the Investor or its designated wholly-owned Designee , and the Investor or such Designee shall purchase and acquire from the Company, the Purchased Units, free and clear of any Liens, other than Liens incurred by the Investor or its respective Affiliates or restrictions arising under applicable securities Laws or imposed by this Agreement, the Organizational Documents of the Company or the Transaction Documents (the “Issuance”).

(b) In consideration for the Issuance, at the Closing, the Investor shall pay or cause to be paid the Purchase Price to the Company in accordance with Section 1.3(b)(i).

None of the Company, the Investor or any of their respective Affiliates shall take any position inconsistent with this Section 1.4 on any U.S. federal or state income Tax Return or in connection with any Action relating to such Tax Return, in each case, except to the extent required pursuant to a “final determination” within the meaning of Section 1313(a) of the Code (or any similar provision).

Section 1.5 Tax Withholding. Each of the Investor, the Company and their respective Affiliates shall be entitled to deduct and withhold from amounts otherwise payable in connection with this Agreement that are required to be deducted and withheld under applicable Law; provided that if the Investor reasonably believes that any withholding of Tax is required with respect to the payment of the Purchase Price, then it shall use commercially reasonable efforts to give written notice to the payee at least five (5) Business Days prior to deducting or withholding such Taxes from such payment, and it shall provide the applicable payee a reasonable opportunity to provide any applicable certificates, forms or documentation that would reduce or eliminate such withholding, and will otherwise reasonably cooperate with the payee and take such steps as payee may reasonably request to reduce or eliminate the requirement to withhold Tax with respect to such payment under applicable Law; provided, further, that the Investor acknowledges that as of the date hereof, it is not aware of any Tax required to be withheld with respect to the payment of the Purchase Price. To the extent amounts are so deducted and withheld and remitted to the applicable Tax authority, such deducted and withheld amounts will be treated for all purposes as having been paid to the Person in respect of whom such deduction and withholding was made.

ARTICLE II

REPRESENTATIONS AND WARRANTIES OF THE INVESTOR

Except as set forth in the correspondingly numbered sections or subsections of the disclosure letter delivered to the Company by the Investor (the “Investor Disclosure Letter”) concurrently with the execution and delivery of this Agreement (it being agreed that each section of the Investor Disclosure Letter 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 on the face of such disclosure), the Investor represents and warrants that:

Section 2.1 Organization and Qualification. The Investor is a joint stock company duly organized and validly existing (with respect to the jurisdictions which recognize such concept) under the Laws of its respective jurisdiction of organization. The Investor and, if applicable, its Designee, have all requisite corporate or entity power and authority to own, lease and operate its properties and assets and to carry on its business as presently conducted. The Investor and, if applicable, its Designee, are duly qualified or licensed and has all necessary governmental approvals, to do business and is in good standing 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 (to the extent that the “qualification to do business” or “good standing” concept is applicable in the case of any jurisdiction outside the United States), 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, an Investor Material Adverse Effect.

Section 2.2 Authorization; Xxxxxxxx; Enforcement. The Investor has all requisite corporate or entity power and authority to execute, deliver and perform its obligations under this Agreement and the applicable Transaction Documents and to consummate the Transactions. The execution, delivery and performance of this Agreement and the applicable Transaction Documents by the Investor and the consummation by the Investor of the Transactions have been duly authorized and approved by all necessary action by the Investor, and no further action, approval or authorization by any of its stockholders, partners, members or other equity owners, as the case may be, is necessary to authorize the execution, delivery and performance by the Investor of this Agreement and the applicable Transaction Documents and the consummation by the Investor of the Transactions. Prior to the Closing, each of the Investor’s Affiliates will have all requisite corporate or entity power and authority and have taken all corporate, entity or other action necessary in order to execute, deliver and perform its obligations under the Transaction Documents which they are party to, and the performance of such Transaction Documents and the consummation of such Transactions by the Investor’s Affiliates will have been duly authorized by all necessary shareholder, corporate or entity action on the part of such Affiliates. This Agreement and the applicable Transaction Documents have been (or will be, upon execution) duly executed and delivered by the Investor or its Affiliates party thereto and shall constitute the legal, valid and binding obligations of the Investor or such Affiliate, enforceable against the Investor or such Affiliate in accordance with their respective terms, subject to bankruptcy, insolvency, fraudulent conveyance of preferential transfers, reorganization, moratorium and similar Laws of general applicability relating to or affecting creditors’ rights and to general equity principles (the “Bankruptcy and Equity Exception”).

Section 2.3 Governmental Filings. Other than in connection with or in compliance with (a) the laws of the State of Delaware, (b) applicable state securities, takeover and “blue sky” Laws and (c) the Antitrust Laws and other Laws set forth in Section 3.3(a) of the Company Disclosure Letter no other consent of, or filing with, any Governmental Authority is necessary, under applicable Law, for the consummation by the Investor and, if applicable, its Designee, of

the Transactions, except for such consents or filings that, if not obtained or made, would not reasonably be expected to have, individually or in the aggregate, an Investor Material Adverse Effect. The Investor and its Affiliates do not hold five percent (5%) or more of the voting securities or non-corporate interests (as “hold,” “voting securities,” and “non-corporate interests” are defined under 16 CFR 801) of any entity that competes with the Company or the SiC Business, to the extent that any such holdings would not reasonably be expected to prevent or materially delay the expiration or termination of the waiting period or the obtaining or receiving of any consent or approval under any Antitrust Law in connection with the Transactions.

Section 2.4 No Conflicts. The execution and delivery by the Investor of this Agreement do not, and (assuming the consents referenced in Section 2.3 are obtained) the consummation of the Transactions and compliance with the provisions hereof will not (a) result in any loss, or suspension, limitation or impairment of any right of the Investor or any of its Affiliates to own or use any assets required for the conduct of their business or result in any violation of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation, first offer, first refusal, modification or acceleration of any material obligation or to the loss of a benefit under any Contract, license or permit binding upon the Investor or any of its Affiliates or by which or to which any of their respective properties, rights or assets are bound or subject, or result in the creation of any Liens other than Permitted Liens (provided that no Lien shall be deemed created by this Agreement or the Transaction Documents) upon any of the properties or assets of the Investor or any of its Affiliates, (b) conflict with or result in any violation of any provision of the Organizational Documents of the Investor or (c) conflict with or violate any applicable Laws, except in the case of clauses (a) and (c) for such conflict or violation as would not reasonably be expected to have, individually or in the aggregate, an Investor Material Adverse Effect.

Section 2.5 Sufficient Funds; Financing. As of the date of this Agreement, the Investor has, and at the Closing and at all times prior to the Closing the Investor will have, immediately available funds sufficient to pay the Purchase Price in full, and to pay any fees and expenses of or payable by the Investor or its Affiliates, and to consummate the Transactions on the terms and conditions contemplated by this Agreement. As of the date hereof, the Investor is not aware of any reason why the funds sufficient to fulfill its obligations under this Agreement (including paying the Purchase Price in full, and to pay any fees and expenses of or payable by the Investor or its Affiliates) will not be available on the Closing Date. The Investor expressly acknowledges and agrees that its obligations under this Agreement to consummate the Transactions are not subject to, or conditioned on, the receipt or availability of any funds or financing.

Section 2.6 Purchase for Investment. The Investor on behalf of itself and any Designee acknowledges that the Common Units have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or under any state or other applicable securities Laws. The Investor and, if applicable, its Designee is an Accredited Investor, and is aware that the sale of the Purchased Units is being made in reliance on a private placement exemption from registration under the Securities Act. The Investor and, if applicable, its Designee is not an underwriter within the meaning of Section 2(a)(11) of the Securities Act. The Investor and, if applicable, its Designee is acquiring the Purchased Units for its own account, and not with a view toward, or for sale in connection with, any distribution thereof in violation of any federal or

state securities or “blue sky” Laws, or with any present intention of distributing or selling such Purchased Units. The Investor and, if applicable, its Designee has sufficient knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risks of its investment in such Purchased Units and is capable of bearing the economic risks of such investment. The Investor and, if applicable, its Designee has been provided a reasonable opportunity to undertake and has undertaken such investigation and has been provided with and has evaluated such documents and information as it has deemed necessary to enable it to make an informed and intelligent decision with respect to the execution, delivery and performance of this Agreement. Neither the Investor nor any of its Affiliates is acting in concert, and neither the Investor nor any of its Affiliates has any agreement or understanding and is not otherwise a member of a “group” (as such term is used in Section 13(d)(3) of the Exchange Act), with any Person that is not an Affiliate of the Investor, with respect to the Company or its securities.

Section 2.7 Brokers; Finders. No broker, investment banker, financial advisor or other Person is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission, or the reimbursement of expenses in connection therewith, in connection with the Transactions based upon arrangements made by or on behalf of the Investor or any of its Affiliates, except for Persons, if any, whose fees and expenses will be paid by the Investor.

Section 2.8 No Other Representations or Warranties; Non-Reliance. Except for the representations and warranties expressly made in Article III (as modified by the Company Disclosure Letter and the Coherent SEC Documents) and in any certificate delivered by the Company pursuant to Article V, the Investor hereby acknowledges and agrees that neither the Company, Coherent nor any of their respective Affiliates or Representatives, nor any other Person, has made or is making any other express or implied representation or warranty, including with respect to the SiC Business, the Purchased Units, the Company, Coherent or any of their respective Affiliates or their respective businesses, operations, properties, assets, liabilities, condition (financial or otherwise) or prospects, notwithstanding the delivery or disclosure to the Investor or its Affiliates or Representatives of any documentation, forecasts or other information with respect to any one or more of the foregoing. In particular, and without limiting the generality of the foregoing, the Investor acknowledges and agrees that except for the representations and warranties made in Article III (as modified by the Company Disclosure Letter and the Coherent SEC Documents) and in any certificate delivered by the Company pursuant to Article V, none of the Company, Coherent, their respective Affiliates, Representatives or any other Person makes or has made any express or implied representation or warranty to the Investor or its Affiliates or Representatives with respect to (a) any financial projection, forecast, estimate, budget or prospect information relating to the Company, Coherent, the SiC Entities, any of their respective Affiliates or their respective businesses or (b) any oral or written information presented to the Investor or its Affiliates or Representatives in the course of the negotiation of this Agreement or the course of the Transactions or any other transactions or potential transactions involving the Investor, Coherent and the Company. The Investor acknowledges and agrees that in making the decision to enter into this Agreement and consummate the Transactions, the Investor has relied exclusively on the express representations and warranties contained in Article III (as modified by the Company Disclosure Letter and the Coherent SEC Documents) and in any certificate delivered by the Company pursuant to Article V and has not relied on any other representation or warranty, express or implied.

(a) Except as would not materially impede or delay the consummation of the Transactions and which would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, other than in connection with or in compliance with (i) the laws of the State of Delaware, (ii) applicable state securities, takeover and “blue sky” Laws and (iii) the Antitrust Laws and other Laws set forth in Section 3.3(a) of the Company Disclosure Letter (collectively, the “Company Approvals”), no other consent of, or filing with, any Governmental Authority is necessary, under applicable Law, for the consummation by the Company of the Transactions, except for such consents or filings as are not required to be obtained or made prior to consummation of the Transactions.

The Financial Statements, which have been derived from the accounting books and records of the SiC Business, were prepared in accordance with GAAP, applied on a consistent basis throughout the periods presented, and fairly present in all material respects the combined financial position and the combined results of operations of the SiC Business, as of the respective dates thereof or the periods then ended, in each case except as may be noted therein and, with respect to unaudited or interim financial statements, subject to adjustments (none of which is expected to be material) and the absence of footnote disclosures; provided that the Financial Statements and the foregoing representations and warranties are qualified by the fact that (A) the SiC Business has not operated on a separate standalone basis and historically been reported within Coherent’s and its Affiliates’ consolidated financial statements, (B) the Financial Statements assume certain allocated charges which do not necessarily reflect amounts that would have resulted from arm’s-length transactions or that the SiC Business would incur on a standalone basis and (C) the Financial Statements are not necessarily indicative of what the results of operations, financial position and cash flows of the SiC Business will be in the future.

(b) As of the Closing, the Company will have established and maintain a system of internal accounting controls designed to provide reasonable assurances (i) that transactions, receipts and expenditures of the SiC Entities are being executed and made only in accordance with appropriate authorizations, (ii) that transactions are recorded as necessary (A) to permit preparation of financial statements in conformity with GAAP, and (B) to maintain accountability for assets, (iii) regarding prevention or timely detection of unauthorized acquisition, use or disposition of the assets of the SiC Entities and (iv) that the amount recorded for assets on the books and records of the SiC Entities is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(c) Since the Applicable Date to the date of this Agreement, solely to the extent relating to the SiC Business, and except as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, Coherent has not received any written notice from the SEC or any other Governmental Authority indicating that any of its accounting policies or practices are or may be the subject of any review, inquiry, investigation or challenge by the SEC or any other Governmental Authority.

(d) Except as would not, individually or in the aggregate, reasonably be expected to be material to the SiC Business taken as a whole, and subject to any reserves specifically related to accounts receivable included in the Financial Statements, (i) all accounts receivable of the SiC Business represent valid obligations arising from goods or services actually sold or performed in the ordinary course of business and (ii) there is no material contest, claim, defense or right of setoff, other than returns or warranty work in the ordinary course of business, relating to the amount or validity of such accounts receivable.

(a) Upon the terms and subject to the conditions set forth in this Agreement, (i) the Company shall cooperate with the Investor and use (and shall cause its Affiliates to use) commercially reasonable efforts to, and (ii) the Investor shall cooperate with the Company and use (and shall cause its Affiliates to use) reasonable best efforts to, take or cause to be taken all things necessary, proper or advisable under applicable Laws to consummate the Transactions as promptly as reasonably practicable, including (x) the obtaining of all necessary actions or non-actions, waivers, consents, clearances, approvals and expirations or terminations of waiting periods, including from any Governmental Authority and the making of all necessary registrations and filings and the taking of all steps as may be necessary to obtain an approval, clearance or waiver from, or to avoid an Action or Proceeding by, any Governmental Authority; (y) the obtaining of all necessary consents, approvals or waivers from any other Person and (z) the execution and delivery of any additional instruments necessary to consummate the Issuance and the other Transactions contemplated by this Agreement; provided, however, that in no event shall the Company or any of its Affiliates be required to pay any fee, penalty or other consideration to any third party for any consent or approval required for or triggered by the consummation of the transactions contemplated by this Agreement under any Contract, agreement or otherwise. Neither the Company nor the Investor shall, nor shall the Company or the Investor permit any of their respective Affiliates to, (A) agree to extend any applicable waiting period pursuant to any Antitrust Law with respect to the Transactions without the prior

written consent of the other Party (which consent shall not be unreasonably conditioned, withheld or delayed) or (B) enter into or consummate any transaction, agreement, arrangement, or acquisition of any ownership interest or assets of any Person, the effect of which would reasonably be expected to materially impair, materially delay or prevent the satisfaction or obtaining of any approval or the expiration of any waiting period that is a condition to Closing. Notwithstanding anything to the contrary in this Section 4.2(a), in no event shall Coherent or any of its Affiliates (other than the SiC Entities) be required to become subject to, or consent or agree to, (i) any restrictions or actions that would limit its and its Affiliates’ (other than the SiC Entities) respective freedom of action with respect to their ability to retain, or impose obligations on its or such Affiliates’ future operations with respect to, one or more of its or such Affiliates’ share capital or equity interests, assets (whether tangible or intangible), businesses, divisions, operations, products or product lines, or (ii) any action with respect to, or any amendments or modifications to, the Transaction Documents other than this Agreement.

(b) In furtherance of the foregoing, the Company and the Investor shall, and shall use reasonable best efforts to cause their respective Affiliates, as applicable, to, (i) promptly, but in no event later than twenty (20) Business Days after the date hereof (except with respect to CFIUS), or on such later date as mutually agreed to by the Company and Investor, file, or cause to be filed, with the appropriate Governmental Authority, all filings, forms, registrations and notifications (or drafts thereof) required to be filed to consummate the Issuance and the other transactions contemplated by this Agreement under any applicable Antitrust Law and (ii) supply, or cause to be supplied, as promptly as practicable any additional information or documentary material that may be requested pursuant to any Law or by any Governmental Authority and, as applicable, to certify substantial compliance with any such request as promptly as practicable.

(c) The Company and Investor shall, and shall cause their respective Subsidiaries and Affiliates, as applicable, to cooperate with one another to prepare and deliver, as promptly as practicable after the date of this Agreement, a briefing to CFIUS regarding the transactions contemplated by the Agreement (the “CFIUS Briefing”). If, and only if, (i) CFIUS requests that the Parties file a notice or declaration with respect to the transactions contemplated by this Agreement (a “CFIUS Notice Request”), or (ii) the Company and Investor mutually agree in writing (including following the Closing), the Company and Investor shall, and shall cause their respective Subsidiaries and Affiliates, as applicable, to submit or cause to be submitted (x) as promptly as practicable following the CFIUS Notice Request or the Company and Investor mutually agreeing in writing to file a notice or declaration to CFIUS a draft of the joint voluntary notice to CFIUS (“CFIUS Notice”) contemplated under 31 C.F.R. § 800.501(g) or a voluntary declaration to CFIUS contemplated under 31 C.F.R. § 800.402 with respect to the transactions contemplated by this Agreement; (y) as promptly as practicable after receiving feedback from CFIUS regarding any draft CFIUS Notice referenced in clause (x) of this Section 4.2(c), a formal CFIUS Notice as contemplated by 31 C.F.R. § 800.501(a); and (z) as promptly as practicable (and in any event in accordance with applicable regulatory requirements) any other submissions that are formally requested by CFIUS to be made, or which the Company and Investor mutually agree should be made, in each case in connection with this Agreement. The Company and the Investor shall cooperate with each other in connection with any such filing or the provision of any such information (including by considering all reasonable additions, deletions or changes suggested in connection therewith, and, to the extent permitted by applicable law, providing copies, or portions

thereof, of all such documents to the non-filing party prior to filing, subject to, as necessary, redactions of confidential business information or the privileged information of either party) and in connection with resolving any investigation or other inquiry of any Governmental Authority under Section 721 with respect to any such filing or any such information.

(d) Notwithstanding the foregoing or anything to the contrary in this Section 4.2, in no event shall (w) the Company, the Investor or their respective Affiliates be required to commit to or effect, by consent decree, hold separate order or otherwise, the sale, divestiture, exclusive licensing, holding separate or any other similar disposition, including discontinuation, of any and all of the share capital or other equity voting interest, assets (whether tangible or intangible), businesses, divisions, operations, products or product lines of the Company, the Investor or any of their respective Subsidiaries, (x) Coherent or any of its Affiliates (other than the SiC Entities) be required to become subject to, or consent or agree to or otherwise take any actions contemplated in this Section 4.2(d) or (y) the Company or any of its Affiliates be required to consent or agree to or otherwise take any actions contemplated in this Section 4.2(d) if, in the case of this clause (y), such actions individually or in the aggregate with all other such requirements, would reasonably be expected to impair, other than a de minimis impairment, the SiC Business as conducted as of the date of this Agreement or the anticipated benefits of the Transactions to the Company and its Affiliates; provided, however, that notwithstanding the foregoing, if necessary, proper or advisable to resolve any objections asserted by CFIUS, the United States Federal Trade Commission, the Antitrust Division of the United States Department of Justice, state antitrust enforcement authorities or any other Governmental Authority or Person with respect to the Issuance or the Transactions so as to enable the Closing to occur as promptly as practicable after the date hereof and to avoid or eliminate each and every impediment under any Law, including any Order or other Action, that may be asserted or that is in force by any Governmental Authority or other Person that would or has the effect of preventing or delaying the Closing, the Investor shall, and shall cause its Affiliates to, take or commit to take any action or agree to any undertaking that after the Closing Date would require it or its Affiliates’ to provide information to any Governmental Authority or limit its and its Affiliates’ ability to vote, transfer or otherwise exercise full ownership of, or information or governance rights (including any consent rights or access rights) relating to, the Purchased Units and the Investors and/or its Designee’s rights in its capacity as a member and equityholder of the Company, including by agreeing to a reduction in the number of Purchased Units (provided that any such reduction shall include a proportionate decrease in the Purchase Price payable by the Investor in respect of such Purchased Units).

(e) The Company and Investor shall, and shall use reasonable best efforts to cause their respective Affiliates to, cooperate and consult with each other in good faith with respect to the making of all registrations, filings, notifications, communications, submissions and any other actions pursuant to this Section 4.2. In furtherance of the foregoing, and subject to applicable legal limitations and the instructions of any Governmental Authority, the Company, on the one hand, and Investor, on the other hand, shall keep each other apprised of the status of matters relating to the completion of the Issuance and the Transactions, including promptly furnishing the other with copies of notices or other communications received by the Company or the Investor, as the case may be, or any of their respective Affiliates, from any Governmental Authority with respect to the Issuance and the other Transactions (but not, for the avoidance of doubt, the Other Investments). Subject to applicable Law relating to the exchange of

information, the Company, on the one hand, and Investor, on the other hand, shall permit counsel for the other party a reasonable opportunity to review in advance, and consider in good faith the views of the other party in connection with, any proposed notifications or filings and any communications or submissions, and with respect to any such notification, filing, communication or submission, submitted therewith to any Governmental Authority in connection with the Issuance and the other Transactions (but not, for the avoidance of doubt, the Other Investments); provided, however, that materials may be redacted (i) to remove references concerning the valuation of the businesses of the Company and its Subsidiaries, or proposals from third parties with respect thereto, (ii) as necessary to comply with contractual agreements and (iii) as necessary to address reasonable privilege or confidentiality concerns. Each of the Company and Investor agrees not to, and shall not permit any of their respective Affiliates to, participate in any meeting or discussion, either in Person, by videoconference, by telephone or otherwise, with any Governmental Authority in connection with the Issuance or the other Transactions (but not, for the avoidance of doubt, the Other Investments) unless it consults with the other Party in advance and, to the extent not prohibited by such Governmental Authority, gives the other Party the opportunity to attend and participate thereat. Subject to the foregoing and Investor’s obligations as set forth in this Section 4.2, the Company shall control and lead the strategy and content of any substantive communications with any Governmental Authority with respect to obtaining approval or expiration of any waiting period under any applicable Antitrust Laws and Section 721.

(b) The Company shall use commercially reasonable efforts to (and use commercially reasonable efforts to cause its Affiliates to), and shall be permitted to, take all actions and do all things necessary, proper and advisable, subject to the requirements of applicable Law and of any Governmental Authority, to prepare, execute and consummate the Separation at or prior to the Closing, and in any event at least six (6) Business Days prior to the Outside Date, subject to the applicable terms and conditions of the Separation Documentation. To the extent not provided to the Investor prior to the date hereof, the Company shall provide drafts of the Separation Documentation to the Investor reasonably in advance of the consummation of the transactions contemplated thereby and shall consider in good faith any comments thereto provided promptly by the Investor following its receipt thereof.

(c) The Company shall keep the Investor apprised on a reasonably timely basis of the status of the Separation and shall promptly notify the Investor when the Separation has been consummated.

promptly as practicable all customer Contract consents required as a result of the Transactions and waiver of any termination, acceleration of payment or default rights triggered as a result of the Transactions; provided, that in no event shall the Company or any of its Affiliates be required to pay any fee, penalty or other consideration to any third party for any consent or approval in connection with clause (ii).

(e) The Company shall, and shall cause its Affiliates to, terminate, effective as of or prior to the Closing, the Intercompany Agreements (other than any Intercompany Agreements listed on Section 3.16(a) of the Company Disclosure Letter and the Transaction Documents).

From the date of this Agreement until the earlier of the Closing or the termination of this Agreement in accordance with its terms, the Investor and the Company shall consult with each other before they or their Affiliates issue, and shall give each other the opportunity to review and comment upon, any press release or other public statements with respect to this Agreement, the Transaction Documents or the Transactions, and shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable Law, Order, court process or the rules and regulations of any national securities exchange or national securities quotation system, in which case the Company or the Investor, as applicable, shall have the right to review and reasonably comment on such press release, announcement or communication prior to issuance, distribution or publication to the extent practicable. Notwithstanding the foregoing (but subject to the terms of the Confidentiality Agreement and Section 4.6), this Section 4.4 shall not apply to any press release or other public statement (including statements in response to questions by the press, business partners, analysts, investors or analyst or the Investor calls) made by the Company, Coherent or the Investor (or any of their Affiliates) (a) which does not contain any information relating to the Transactions that has not been previously announced or made public in accordance with the terms of this Agreement or (b) is made in the ordinary course of business and does not relate specifically to this Agreement, the Transaction Documents or the Transactions.

(c) Except for Losses resulting from Fraud on the part of the Company or its Affiliates, notwithstanding anything to the contrary herein, the cumulative indemnification obligations of the Company under Section 7.2(a) shall in no event exceed, in the aggregate, the Purchase Price.

Section 7.4 Indemnification Procedures.

(a) A Person that may be entitled to be indemnified under this Agreement (the “Indemnified Party”) shall promptly notify the Party liable for such indemnification (the “Indemnifying Party”) in writing of any pending or threatened Action, or any other matter or circumstance that arises, that has given or could reasonably be expected to give rise to a right of indemnification under this Agreement (including a pending or threatened Action asserted by a third party against the Indemnified Party, such claim being a “Third Party Claim”); provided that such notice shall describe in reasonable detail the facts and circumstances with respect to the subject matter of such Action, matter or circumstance (including, in the case of a Third Party Claim, the identity of the applicable third party and the facts underlying each particular claim to the extent reasonably practicable), attach copies of any written evidence or demand upon which such claim is based, identify the provisions of this Agreement pursuant to which indemnification

may be sought, include an estimate of the Indemnified Party’s Losses to the extent reasonably practicable and must be delivered prior to the expiration of any applicable survival period specified in Section 7.1; provided, further, that, subject to the applicable survival period in Section 7.1, the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article VII except to the extent the Indemnifying Party is prejudiced by such failure.

(b) Upon receipt of a notice of a Third Party Claim for indemnity from an Indemnified Party pursuant to Section 7.2 or Section 7.3, the Indemnifying Party will be entitled, by notice to the Indemnified Party delivered within thirty (30) days after the receipt of notice of such Third Party Claim, to assume the defense and control of such Third Party Claim (at the expense of such Indemnifying Party); provided that the Indemnifying Party shall allow the Indemnified Party a reasonable opportunity to participate in the defense of such Third Party Claim with its own counsel and at its own expense. If the Indemnifying Party does not assume the defense and control of any Third Party Claim pursuant to this Section 7.4(b), the Indemnified Party shall be entitled to assume and control such defense, but the Indemnifying Party may nonetheless participate in the defense of such Third Party Claim with its own counsel and at its own expense. If the Indemnifying Party assumes the defense and control of a Third Party Claim, the Indemnifying Party shall be entitled to select counsel, contractors and consultants reasonably acceptable to the Indemnified Party. Investor or the Company, as the case may be, shall, and shall cause each of their controlled Affiliates and representatives to, reasonably cooperate with the Indemnifying Party in the defense of any Third Party Claim, including by furnishing books and records, personnel and witnesses, as appropriate for any defense of such Third Party Claim. If the Indemnifying Party has assumed the defense and control of a Third Party Claim, it shall be authorized to consent to a settlement of, or the entry of any judgment or Order arising from, any Third Party Claim, in its sole discretion and without the consent of any Indemnified Party; provided that such settlement or judgment or Order does not involve any injunctive relief or finding or admission of any violation of Law or admission of any wrongdoing by any Indemnified Party. No Indemnified Party will consent to the entry of any judgment or enter into any settlement or compromise with respect to a Third Party Claim without the prior written consent of the Indemnifying Party (which will not be unreasonably withheld, delayed or conditioned).

(c) Notwithstanding any of the foregoing, the Company shall have the exclusive right to control in all respects, and neither Investor nor any of its Affiliates shall be entitled to participate in, any Action with respect to any Tax Return of (i) the Company or any of its Affiliates or (ii) a consolidated, combined, unitary or similar group that includes the Company or any of its Affiliates.

Section 7.5 Exclusive Remedy; No Recourse.

(a) Investor and the Company acknowledge and agree that, except (i) in connection with Fraud or a Willful and Material Breach of this Agreement, and (ii) for the Parties’ right to seek and obtain any equitable relief pursuant to Section 8.1(d), from and after the Closing, the indemnification provisions of Section 7.2 and Section 7.3 shall be the sole and exclusive remedies of the Company and the Investor for any Liabilities or Losses (including any Liabilities or Losses from claims for breach of contract, warranty, tortious conduct (including

negligence) or otherwise and whether predicated on common law, statute, strict liability or otherwise) that either party may at any time suffer or incur, or become subject to, as a result of, or in connection with the purchase of the Purchased Units or the other Transactions, including any breach of any representation, warranty, covenant or agreement in this Agreement or the Agreements contemplated hereby (but excluding the other Transaction Documents to which the Investor or its Affiliates, on the one hand, or the Company or any SiC Entity, on the other hand, is a party (including the Confidentiality Agreement)). Without limiting the generality of the foregoing, each Party hereby irrevocably waives any right of rescission it may otherwise have or to which it may become entitled.

(b) Notwithstanding anything to the contrary herein, all Actions, claims, obligations, liabilities or causes of action (whether in Contract or in tort, in Law or in equity or otherwise, or granted by statute or otherwise, whether by or through attempted piercing of the corporate, limited partnership or limited liability company veil or any other theory or doctrine, including alter ego or otherwise) that may be based upon, in respect of or arise under: (i) this Agreement or any other Transaction Document, or any of the transactions contemplated hereunder or thereunder, (ii) the negotiation, execution or performance of this Agreement or any other Transaction Document (including any representation or warranty made in, in connection with, or as an inducement to, this Agreement or any other Transaction Document), (iii) any breach or violation of this Agreement or any other Transaction Document and (iv) any failure of any of the transactions contemplated hereunder or under any other Transaction Documents to be consummated, in each case, may be made only against (and are those solely of) the Persons that are, in the case of this Agreement, expressly identified as parties to this Agreement or, in the case of the other Transaction Documents, Persons that are expressly identified as parties to such other Transaction Documents (collectively, the “Named Parties”). For the avoidance of doubt, this Section 7.5(b) is intended to benefit and may be enforced by any past, present or future director, officer, employee, incorporator, member, partner, stockholder, Affiliate, agent, attorney, advisor or representative of any Named Party (and each such Person shall be a third-party beneficiary of this Section 7.5(b)) and shall be binding on all respective successors and permitted assigns thereof.

(c) The Company and Investor agree that the limits imposed on remedies with respect to this Agreement and the Transactions constitute an integral part of the consideration provided to the Company hereunder, were specifically bargained for between sophisticated parties and their respective counsel and were specifically taken into account in the determination of the amounts to be paid to the Company hereunder.

Section 7.6 Additional Indemnification Provisions. With respect to each indemnification obligation contained in this Agreement, all Losses shall be reduced by the amount of any third-party insurance or reimbursement proceeds that have been recovered by the Indemnified Party in connection with the facts giving rise to the right of indemnification (it being agreed that if such proceeds in respect of such facts are recovered by the Indemnified Party subsequent to the Indemnifying Party’s making of an indemnification payment in satisfaction of its applicable indemnification obligation, such proceeds shall be promptly remitted to the Indemnifying Party to the extent such reduction of the Losses would have reduced the Indemnifying Party’s indemnification obligations), and the Indemnified Party shall use, and cause its Affiliates to use, reasonable best efforts to seek full recovery under all insurance and

other indemnity and reimbursement provisions covering such Losses to the same extent as it would if such Losses were not subject to indemnification hereunder. Upon making any payment to the Indemnified Party for any indemnification claim pursuant to this Article VII, the Indemnifying Party shall be subrogated, to the extent of such payment, to any rights or claims which the Indemnified Party may have against any third parties with respect to the subject matter underlying such indemnification claim, and the Indemnified Party shall assign any such rights or claims to the Indemnifying Party or, where such assignment is not permitted, use commercially reasonable efforts to recover in respect of such rights or claims against the third parties on behalf of the Indemnifying Party.

Section 7.7 Limitation of Liability. In no event shall any Indemnifying Party have Liability to any Indemnified Party for, and Losses shall not be deemed to include, any consequential, special, incidental, exemplary, indirect, punitive or similar damages, or for any loss of future revenue, profits or income, or for any diminution in value damages measured as a multiple of earnings, revenue or any other performance metric (even if under Law such lost profits, opportunity costs or damages based upon a multiple of earnings, revenues or similar financial measure would be considered reasonably foreseeable or not special damages), except for any such damages to the extent actually awarded by a court or arbitration body of competent jurisdiction and paid to a third party. No Indemnified Party shall have any right to assert any claim against any Indemnifying Party with respect to any Loss to the extent such alleged Loss is a possible or potential Loss the Indemnified Party believes may be asserted rather than an actual Loss that has, in fact, been actually paid or incurred by such Indemnified Party. Neither the Investor Indemnified Parties, on the one hand, nor the Company Indemnified Parties, on the other hand, shall be entitled to recover more than once in respect of any Loss. Where one and the same set of facts, circumstances or events qualifies under more than one provision entitling an Indemnified Party to a claim or remedy hereunder, such Indemnified Party shall not be entitled to duplicative recovery of Losses arising out of such facts, circumstances or events. Notwithstanding any other provision of this Agreement, in no event shall any Indemnified Party be entitled to indemnification pursuant to this Article VII to the extent such Losses were attributable to such Indemnified Party’s own fraud, gross negligence or willful misconduct.

Section 7.8 Mitigation. Each of the parties agrees to use, and to cause its Affiliates to use, its reasonable best efforts to mitigate its respective Losses upon and after becoming aware of any event or condition that would reasonably be expected to give rise to any Losses that are indemnifiable hereunder, and no Indemnifying Party shall be liable for any Losses to the extent they arise out of or result from the Indemnified Party’s failure to use reasonable best efforts to mitigate such Losses.

Section 7.9 Opportunity to Remedy. If any matter or circumstance for which a right of indemnification is available under this Agreement is capable of remedy, the Indemnified Party shall only be entitled to indemnification to the extent that the matter or circumstance is not remedied within thirty (30) days after the date on which the relevant notice is served on the Indemnifying Party in accordance with Section 7.4.

The terms “or,” “any” and “either” are not exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if”. The word “will” shall be construed to have the same meaning and effect as the word “shall.” The phrase “made available” (or words of similar import) when used in reference to anything made available to Investor or any of its Representatives will mean uploaded to and made available to Investor and its Representatives in the on-line data room hosted on behalf of the Company in the on-line workspace captioned “Project Eagle” on Intralinks or such item has been provided directly to Investor or any its Representatives, in each case on or prior to 10:00 a.m. Eastern Time on the date that is one (1) Business Day prior to the date of this Agreement.

The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument or statute defined or referred to in this Agreement means such agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes. References to “ordinary course,” “ordinary course of business,” and phrases of similar import shall encapsulate an action taken by

any Person, or omitted to be taken, in response to COVID-19 or any COVID-19 Measures and any Cybersecurity Measures; provided that with respect to the Company and its Affiliates, “ordinary course,” “ordinary course of business,” and phrases of similar import shall (x) include any action taken, or omitted to be taken, in connection with the Separation and (y) with respect to Company and its Subsidiaries, include any action taken, or omitted to be taken, that would satisfy such standard if taken by Coherent or its Subsidiaries prior to the Separation. All accounting terms used herein and not expressly defined shall have the meanings given to them under GAAP. When calculating the period of time between which, within which or following which any act is to be done or step taken pursuant to this Agreement, the date that is the reference date in calculating such period shall be excluded (unless, otherwise required by Law, if the last day of such period is not a Business Day, the period in question shall end on the next succeeding Business Day).

(b) Each of the Parties has participated in the drafting and negotiation of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if it is drafted by each of the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of authorship of any of the provisions of this Agreement.
