(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

22

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.

(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.

31

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.

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

33

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 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.
