You agree to notify the Company of any days or days during the exclusion period when you will be unavailable due to holiday and will endeavour to agree convenient holiday dates in advance with the Company. 15.5 Reasonable Assistance Before and after termination of your employment, you will provide the Company and/or any Group Company with reasonable assistance regarding matters of which you have knowledge and/or experience in any proceedings or possible proceedings in which the Company and/or Group Company is or may be a party. 15.6 Duties Upon Notice of Termination At any time after notice (including summary notice) to terminate this Agreement has been served or received by the Company, the Company may require you to: (i) transfer, without payment, to the Company (or as the Company may direct) any nominee shareholdings provided to you by or held by you in or on behalf of any Group Company; and/or (ii) return to the Company on request any documents, computer disks and tapes and other tangible items in your possession or under your control which belong to the Company or any Group Company or which contain or refer to any confidential information; and/or (iii) delete all confidential information from any computer, disks, tapes, or other re- usable material in your possession or under your control and destroy all other documents and tangible items in your possession or under your control which contain or refer to any confidential information; and/or (iv) resign immediately, without additional compensation, from any office that you hold in or on behalf of any Group Company; and/or (v) provide a signed statement that you have complied fully with your obligations under this clause 15.6, together with such reasonable evidence of compliance as the Company may request. If you fail to comply with clauses 15.6(i) through 15.6(v) within seven days of being required, the Company is hereby irrevocably authorised to appoint some person in your name and on your behalf to sign any document or do anything necessary or requisite to effect such resignation(s) and/or transfer(s) (without prejudice to any claims which you may have against the Company arising out of this Agreement or its termination). 15.7 Change in Control 15.7.1 For purposes of this Agreement, a “Change in Control” will be deemed to have occurred upon the occurrence of any of the following events:

14 (i) the acquisition by any individual, entity or group [within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended from time to time (the “Exchange Act”)] (a “Person”) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of voting securities of the Company where such acquisition causes such Person to own 35% or more of the combined voting power of the then outstanding voting securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); provided, however, that for purposes of this subsection (i), the following acquisitions will not be deemed to result in a Change in Control: (A) any acquisition by the Company or a Group Company, (B) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any Group Company, or (C) any acquisition by any Person pursuant to a transaction that complies with clauses (A), (B) and (C) of subsection (iii) below; provided, further, that if at least a majority of the members of the Incumbent Board determines in good faith that a Person has acquired beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 35% or more of the Outstanding Company Voting Securities inadvertently, and such Person divests as promptly as practicable a sufficient number of shares so that such Person beneficially owns (within the meaning of Rule 13d-3 promulgated under the Exchange Act) less than 35% of the Outstanding Company Voting Securities, then no Change in Control will have occurred as a result of such Person’s acquisition and provided, further, that if any Person’s beneficial ownership reaches or exceeds 35% as a result of a reduction in the number of the Company’s ordinary shares then outstanding due to the repurchase of ordinary shares by the Company, unless and until such time as such Person will purchase or otherwise become the beneficial owner of additional voting securities of the Company representing 1% or more of the Outstanding Company Voting Securities; (ii) individuals who, as of the Commencement Date, constitute the Board (the “Incumbent Board” as modified by this subsection (ii)) cease for any reason to constitute at least a majority of the Board; provided, however, that any individual becoming a director subsequent to the Commencement Date whose election, or nomination for election by the Company’s shareholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board (either by specific vote or by approval of the proxy statement of the Company in which such person is named as a nominee for director, without objection to such nomination) will be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board; (iii) the consummation of a reorganization, merger, or consolidation or sale or other disposition of all or substantially all of the assets of the Company or the acquisition of assets of another company or other transaction (“Business Combination”) excluding, however, such a

15 Business Combination pursuant to which (A) the individuals and entities who were the beneficial owners of the Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 65% of, respectively, the then outstanding shares of common stock and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the entity resulting from such Business Combination (including, without limitation, an entity that as a result of such transaction owns the Company or all or substantially all of the Company’s assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership immediately prior to such reorganization, merger or consolidation of the outstanding ordinary shares, (B) no Person (excluding any employee benefit plan (or related trust) of the Company or a Group Company, the Company, a Group Company, or such entity resulting from such Business Combination) beneficially owns, directly or indirectly, 30% or more of the combined voting power of the then outstanding securities entitled to vote generally in the election of directors of the entity resulting from such Business Combination, and (C) at least a majority of the members of the board of directors of the company resulting from such Business Combination were members of the Incumbent Board at the time of the execution of the initial agreement, or of the action of the Board, providing for such Business Combination; or (iv) approval by the Company’s shareholders of a complete liquidation or dissolution of the Company except pursuant to a Business Combination that complies with clauses (A), (B) and (C) of subsection (iii) above. 15.7.2 If your employment by the Company is terminated in connection with a Change in Control where the Transfer of Undertakings (Protection of Employment) Regulations 2006 do not apply and: (i) you receive an offer or employment with any company or Person concerned with such Change in Control (each a “Successor”); and (ii) the offer is for employment of a similar nature (whether or not involving a change of status) and on terms generally no less favourable than those of your employment under this Agreement (an “Equivalent Position”) then you shall not be entitled to any additional remuneration or benefits with respect to the Change in Control, and you shall have no claim against the Company in respect of the termination of your employment. 15.7.3 If your employment by the Company is terminated in connection with a Change in Control (other than in circumstances set forth in sub-clause 15.2.2) and you do not receive an offer of employment for an Equivalent Position with a Successor, then the Company shall pay you the following remuneration and benefits: (i) a redundancy payment equal to two times your base salary at the annualized rate in effect on the Termination Date (less such tax and national insurance, and any pension contributions, as may be properly deductible);

16 (ii) your actual bonus earned for the fiscal year in which your employment terminates (less such tax and national insurance, and any pension contributions, as may be properly deductible). If, as of the Termination Date, the actual bonus amount earned has not been determined because the relevant performance period remains ongoing, your bonus for the fiscal year in which your employment terminates shall be paid at Budget level; and (iii) immediate vesting of outstanding equity awards in accordance with the ‘Change in Control’ rules of the LTIP. 16. RESTRICTIONS FOLLOWING TERMINATION 16.1 In this clause 16 the following expressions have the following meanings: “Critical Person” any person who was an employee, agent, director, consultant or independent contractor employed, appointed, or engaged by the Company or any Relevant Group Company at any time within the Relevant Period who by reason of such employment, appointment or engagement and in particular his/her seniority and expertise or knowledge of trade secrets or confidential information of the Company or any Group Company or knowledge of or influence over the clients, customers or suppliers of the Company or any Group Company is likely to be able to assist or benefit a business in or proposing to be in competition with the Company or any Relevant Group Company; “Products or Services” products or services which are of the same kind as or of a materially similar kind to or competitive with any products or services sold or supplied by the Company or any Relevant Group Company within the Relevant Period prior to you leaving the Company for whatever reason; “Relevant Customer” any person, firm, company, or organisation who or which at any time during the Relevant Period is or was: • negotiating with the Company or a Relevant Group Company for the sale or supply of the Relevant Products or Services; or • a client or customer of the Company or any Relevant Group Company for the sale or supply of Relevant Products or Services; or • in the habit of dealing with the Company or any Relevant Group Company for the sale or supply of Relevant Products or Services and in each case with whom or which you were directly concerned or connected or of whom or which you had personal knowledge during the Relevant Period in the course of your employment hereunder; “Relevant Group Company” any Group Company (other than the Company) for which you have performed services under this Agreement or for which you had operational/management responsibility at any time during the Relevant Period; “Relevant Period” the period of 12 months immediately before the Termination Date or (where such provision is applied) the commencement of any period of exclusion pursuant to clause 16.2 if earlier;

17 “Relevant Products or Services” Products or services with which sale or supply you were directly or connected or of which you had personal knowledge during the Relevant Period in the course of your employment hereunder; “Restricted Territory” any country in which the Company or any Group Company has a material interest in the sale or supply of Products or Services. 16.2 You will not, without the prior written consent of the Company (such consent not to be unreasonably withheld), directly or indirectly and whether alone or in conjunction with or on behalf of any other person and whether as a principal, shareholder, director, employee, agent, consultant, partner or otherwise: 16.2.1 within the Restricted Territory for a period of twelve months from the Termination Date be engaged, concerned or interested in, or provide commercial or professional advice to, any other business which supplies Products or Services in competition with the Company or any Relevant Group Company provided that this restriction does not apply to prevent you from: (i) undertaking duties or activities which are materially different from those undertaken by you during the Restricted Period in the performance of your duties hereunder; or (ii) holding shares or other securities in any company which is quoted, listed or otherwise dealt in on a recognised investment exchange or other securities market and which confer not more than four per cent of the votes which could be cast at a general meeting of such company; 16.2.2 within the Restricted Territory for a period of twelve months from the Termination Date be engaged, concerned or interested in any business which at any time during the Relevant Period has supplied products or services to the Company or any Relevant Group Company or is or was at any time during the Relevant Period a Relevant Customer of the Company or any Relevant Group Company if such engagement, concern or interest causes or would cause the supplier to cease, alter or materially to reduce its supplies to the Company (or any Relevant Group Company as the case may be) or the Relevant Customer to cease or materially to reduce its orders or contracts with the Company or any Relevant Group Company; 16.2.3 for a period of twelve months from the Termination Date so as to compete with the Company or any Relevant Group Company canvass, solicit or approach or cause to be canvassed, solicited, or approached any Relevant Customer for the sale or supply of Relevant Products or Services or endeavour to do so; 16.2.4 for a period of twelve months from the Termination Date so as to compete with the Company or any Relevant Group Company deal or contract with any Relevant Customer in relation to the sale or supply of any Relevant Products or Services, or endeavour to do so; 16.2.5 for a period of twelve months from the Termination Date solicit, induce or entice away from the Company or any Relevant Group Company or, in connection with any business in or proposing to be in competition with the Company or any Relevant Group Company, employ, engage or appoint or in any way cause to be employed, engaged or appointed a Critical Person whether or not such person would commit any breach of his or her contract of employment or engagement by leaving the service of the Company or any Relevant Group Company; or 16.2.6 use in connection with any business any name, which includes the name of the Company or any Group Company or any colourable imitation of it.

18 16.3 Whilst the restrictions in this clause 16 (on which you have had an opportunity to take independent advice as you hereby acknowledge) are regarded by the parties as fair and reasonable, it is hereby declared that each of the restrictions in this clause 16 is intended to be separate and severable. If any restriction is held to be unreasonably wide but would be valid if part of the wording (including in particular but without limitation the defined expressions referred to in clause 16.1) were deleted, such restriction will apply with so much of the wording deleted as may be necessary to make it valid. 16.4 The parties agree that the periods referred to in sub-clauses 16.2.1, 16.2.2, 16.2.3,16.2.4 and 16.2.5 above will be reduced by one day for every day during which at the Company's direction and pursuant to clause 15.6 above you have been excluded from the Company's premises and/or have not carried out any duties or have carried out duties other than your normal duties. 16.5 If you breach any of the provisions in this clause 16, the Company will be entitled by written notice to you to extend the period during which the provisions of clause 16 which have been breached apply by an equivalent period to that during which the breach or breaches have continued, such additional period to commence on the date on which the said period would have otherwise expired. You hereby agree that if the Company so extends the period of any such restriction, this will not prejudice the right of the Company to apply to the Courts for injunctive relief in order to compel you to comply with the provisions of this clause 16 and/or damages, as the case may be. 16.6 For the purposes of clause 16, the Company has entered into this Agreement as agent for and trustee of all Relevant Group Companies and all Group Companies respectively. 16.7 If you apply for or are offered a new employment, appointment, or engagement, before entering into any related contract you will bring the terms of this Agreement to the attention of a third party proposing directly or indirectly to employ, appoint or engage you. 17. NOTICES Any notice given under this Agreement shall be deemed well served if when addressed to the Company it be left at the address identified in this Agreement or be sent by first class post addressed to that address, or if when addressed to you it be served personally or be sent by first class post addressed to you at the usual or last known address and in case of service by first class post the date of service shall be the date following the date of posting. 18. DATA PROTECTION 18.1 For the purposes of the Data Protection Act 2018, you consent to the processing of all or any personal data (in manual, electronic or any other form) relevant to your employment, by the Company or any Group Company and/or any agent or third party nominated by the Company and bound by a duty of confidentiality. Processing includes, but is not limited to, obtaining, recording, using, and holding data relating to you for legal, personnel, administrative and management purposes and in particular to the processing of any sensitive personal data (as defined in the Data Protection Act 2018) relating to you, including, as appropriate: 18.1.1 Information about your physical or mental health or condition in order to monitor sick leave and take decisions about your fitness to work; 18.1.2 Your racial or ethnic origin or religious or similar information in order to monitor compliance with equal opportunities legislation; 18.1.3 Information relating to any criminal proceedings in which you have been

19 involved for insurance purposes and in order to comply with legal requirements and obligations to third parties. 18.2 The Company may make such information available to any Group Company, those who provide products and services to the Company or any Group Company (such as advisers and payroll administrators), regulatory authorities, potential or future employers, governmental or quasi-governmental organisations and potential purchasers of the Company or any Group Company or the business in which you work. 18.3 You consent to the transfer of such information to any Group Company and the Company or any Group Company business contacts outside the European Economic Area in order to further its or their business interests even where the country or territory in question does not maintain adequate data protection standards. 19. RELEVANT LAW 19.1 This Agreement shall be governed by and construed under the laws of England and Wales and the parties hereto submit to the jurisdiction of the Courts of England and Wales. 19.2 A reference to a particular law is a reference to it as it is in force for the time being taking account of any amendment, extension, or re-enactment and includes any subordinate legislation for the time being in force made under it. 20. OVERRIDING LEGISLATION This Agreement is subject to any overriding legislation. 21. HEADINGS The headings to the clauses of this Agreement are for convenience of reference only and shall not affect the meanings or construction of anything herein contained. 22. ASSIGNMENT The benefit and burden of this Agreement shall devolve upon and be enforceable by and against not only the Company but also its assignees. 23. EFFECT OF TERMINATION The expiration or termination of this Agreement shall not operate to affect any provisions contained in this Agreement, which are specifically expressed such as to operate or have effect after this Agreement has terminated. 24. GRIEVANCE You may refer any grievance to the Company by written submissions in accordance with the Company's Grievance Procedure. To the extent that statute allows for this the Company's Grievance Procedure is not incorporated by reference into this Agreement and therefore does not form part of your contract of employment. 25. DISCIPLINARY PROCEDURE 25.1 The Company has a disciplinary procedure. To the extent that statute allows for this the Company's Disciplinary Procedure is not incorporated by reference into this Agreement and therefore does not form part of your contract of employment.

20 25.2 The Company shall be entitled prior to and during the course of any investigations to suspend you (with or without pay) and exclude you from the premises of the Company if suspension is necessary to allow a proper investigation to be conducted or if there may be circumstances, which would entitle the Company to dismiss you summarily. 26. RIGHTS OF THIRD PARTIES Nothing in this Agreement is intended to confer on any person any right to enforce any term of this Agreement which that person would not have had but for the Contracts (Rights Of Third Parties) Act 1999. 27. STATUTORY INFORMATION The terms set out in this Agreement include those required to be included in a statement of the terms of your employment under section 1 and 2 of the Employment Rights Act 1996, and this Agreement is therefore also the statement required to be given to you. In order to meet the statutory requirements, the Company is required to give particulars of any collective agreements applicable to your employment: there are no such collective agreements applicable by your employment. 28. RESIGNATION AS A DIRECTOR 28.1 If you have been appointed a director of the Company or a Group Company at any time, you will on termination of your employment for any reason at the request of the Board (pursuant to either a resolution of the Board or members of the Company) give notice resigning immediately, without claim for compensation (but without prejudice to any claim you may have for damages for breach of this Agreement): (i) as a director of the Company and all such Group Companies of which you are a director; and (ii) all trusteeships held by you of any pension scheme or other trusts established by the Company or any Group Company or any other company with which you have had dealings as a consequence of your employment with the Company. 28.2 If notice pursuant to clause 28.1 or 15.4(iv) is not received by the relevant company within seven days of a request by the Company, the Company is irrevocably authorised to appoint a person to execute any documents and to do everything necessary to effect such resignation or resignations on your behalf. 28.3 Except with the prior written agreement of the Chief Executive Officer of Luxfer, you will not during your employment under this Agreement resign your office as a director of the Company or any Group Company and if you do so without the consent or concurrence of the Chief Executive Officer of Luxfer, the Company will be entitled to terminate your employment pursuant to sub-clause 15.2.2(v) or at the Company's absolute discretion, to treat such resignation as notice of termination given by you to the Company pursuant to clause 15.1.
