The Expiry Date shall be no later than the Termination Date (as defined in the SPA).

Coltec France may, at its sole option and full discretion, exercise the Offer at any time during the Offer Period by providing the Offeror with an exercise notice in writing (a “Notice of Exercise”).

To be valid, the Notice of Exercise:

Immediately following delivery of a valid Notice of Exercise by Coltec France, Coltec France shall (and EnPro Holdings shall procure that Coltec France shall) execute the adherence agreement to the SPA as set out under Exhibit F of the SPA (the “Adherence Agreement”).

A Notice of Exercise given in accordance with clause 1.4 may not be revoked without the written consent of the Offeror.

If Coltec France does not provide a valid Notice of Exercise on or before the Expiry Date, the Offer shall lapse and cease to be exercisable and, save for clauses 4 (Confidentiality) and 6 (Miscellaneous) of this letter, this Offer shall terminate with immediate effect and all the rights and obligations of the Offeror shall cease, except with respect to the rights, obligations or liabilities which have accrued under this Offer prior to the Expiry Date and which shall continue thereafter.

The Offeror acknowledges that, in accordance with applicable laws, before any decision is made by Coltec France to exercise the Offer, there is an obligation to proceed with the employees’ information and consultation processes detailed in Appendix 2 (the “Employees’ Consultation Processes”) to be commenced as soon as reasonably practicable and no later than 5 Business Days after this date of this Put Option Agreement.

to promptly (and in any event within 48 hours) after receipt, provide to the Offeror a copy of all requests for information and specific questions received from the SEC (as defined in Appendix 2) with respect to the Proposed Transaction that include any request for information or specific questions relating to the Offeror or the future activities of the Business; and

to abstain from giving any commitment, representation or undertaking on behalf or in respect of the Offeror or CPI France, and to procure that CPI France or any of its Affiliates does not make any such commitment, representation or undertaking, during the Employees’ Consultation Processes, without the Offeror’s prior written consent.

The Offeror undertakes to provide to EnPro Holdings and Coltec France such co-operation, information and assistance, in a timely manner, including by attending the relevant employee representative bodies meetings, as EnPro Holdings and Coltec France may reasonably require in connection with the Employees’ Consultation Processes, and providing answers to the questions that may be raised by the relevant employee representative bodies as part of the Employees’ Consultation Processes. Contents of any statements to be made by the Offeror as part of such meetings shall be discussed between EnPro Holdings and Coltec France and the Offeror in good faith ahead of any meeting.

Immediately after giving effect to the transactions contemplated by this Put Option Agreement, the Offeror (a) will be solvent (in that both the fair value of its assets will not be less than the sum of its liabilities and that the present saleable value of its assets will not be less than the amount required to pay its probable liabilities as they become absolute and matured) and (b) will have adequate capital with which to engage in its business.

As from the signing date of this Put Option Agreement by EnPro Holdings and Coltec France, Coltec France and EnPro Holdings shall not, and EnPro Holdings shall procure that the Seller Parties or any of their Affiliates do not (directly or indirectly), offer for sale, solicit any bids from, initiate, engage in or continue any discussions or negotiations with any third party (including by giving them access to information, documents, staff or premises) with respect to the sale of any of the CPI France Shares or any other transaction similar to, or having substantially the same purposes as, the Proposed Transaction (a “Competing Bid”).

Such exclusivity obligations shall terminate upon the earlier of (i) the date of execution of the Adherence Agreement or (ii) the Termination Date (plus 3 months).

Without limiting in any way clause 3.1, EnPro Holdings and Coltec France hereby represents and warrants that as at the date of this Put Option Agreement it (and each Seller Party and their Affiliates) is not in any discussions or negotiations with any person or entity other than the Offeror with respect to any Competing Bid.

Coltec France represents and warrants that (a) the representations and warranties set forth in Article IV of the SPA are true and correct with respect to CPI France, as if CPI France were a Company Entity thereunder on the date hereof and (ii) the representations and warranties set forth in Article V of the SPA are true and correct with respect to Coltec France as if Coltec France were a Seller Party thereunder on the date hereof.

The Offeror acknowledges that it is bound by the terms of the Master Confidentiality Agreement dated as of June 24, 2021 between Howden UK and Robert W. Baird & Co. Incorporated, as agent for EnPro Industries, Inc. (the “NDA”), as if it were a party thereto.

EnPro Holdings and the management of Coltec France will be entitled to communicate on the Proposed Transaction within the Seller Parties (which must not exceed the information appearing in the memorandum to be prepared as part of the Employees’ Consultation Processes).

Notwithstanding anything to the contrary in this Offer and/or the NDA, neither EnPro Holdings, Coltec France nor the Offeror shall bear any responsibility in case of information leakage regarding the Proposed Transaction occurring during the Employees’ Consultation Processes the origin of which is due to the members of the relevant employees’ representative bodies participating in the Employees’ Consultation Processes and not an act or omission of EnPro Holdings or Coltec France (in the case of a breach by EnPro Holdings or Coltec France) or the Offeror (in the case of a breach by the Offeror).

No amendments or modifications to this Offer, or waiver of its terms, shall be valid unless acknowledged in a written instrument signed by the parties hereto.

Except as expressly provided in this Offer, the failure to exercise or delay in exercising a right to remedy provided by this letter or by law does not impair or constitute a waiver of the right or remedy or an impairment of or a waiver of other rights or remedies. No single or partial exercise of a right or remedy provided by this letter or by law prevents further exercise of the right or remedy or the exercise of another right of remedy.

The Offeror irrevocably waives (i) any right to terminate this Offer, (ii) any right it may have to claim that this Offer has lapsed as a result of any other contract contributing to the completion of the transactions contemplated having terminated, lapsed or being ineffective for any reason whatsoever.

Any term or provision of this Offer that is invalid or unenforceable in any jurisdiction will, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Offer or affecting the validity or enforceability of any of the terms or provisions of this Offer in any other jurisdiction.

the parties shall negotiate in good faith to replace the Challenged Provisions with valid and enforceable provisions as close as possible to the common intent of the parties.

The provisions of this letter shall be binding upon the parties’ respective successors and permitted assigns.

The parties hereto agree that irreparable damage may occur if any of the provisions of this letter were not performed in accordance with its specific terms or was otherwise breached and that any nonperformance or breach of this Offer may not be adequately compensated by monetary damages alone and that the parties hereto may not have any adequate remedy at law. Therefore, the parties agree that the parties may be entitled to specific performance and to injunctive relief to prevent breaches or threatened breaches of this Offer, without proof of actual damages or posting of any bond or other undertaking and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which they are entitled hereunder, at law or in equity.
