------

Item 6. Indemnification of Directors and Officers.

Set forth below is a description of certain provisions of the Delaware General Corporation Law (the "DGCL") and the Restated Certificate of Incorporation of the Registrant (as amended, the "Certificate of Incorporation"), as such provisions relate to the indemnification of the directors and officers of the Registrant. This description is intended only as a summary and is qualified in its entirety by reference to the applicable provisions of the DGCL, the Certificate of Incorporation of the Registrant, the Amended and Restated Bylaws of the Registrant (the "Bylaws") and the indemnification agreements entered into by the Registrant and its directors and executive officers.

Section 145 of the DGCL provides that a Delaware corporation has the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation in such capacity in another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person's conduct was unlawful. In the case of an action or suit brought by or in the right of the corporation, indemnification of any director, officer, employee or agent of the corporation (or person serving at the request of the corporation in such capacity in another enterprise) against expenses actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit is permitted if such person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation; however, no indemnification is permitted in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the Delaware Court of Chancery, or the court in which such action or suit was brought, shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court shall deem proper.

The Registrant's Certificate of Incorporation provides that the Registrant shall, to the fullest extent authorized or permitted by the DGCL, (i) indemnify its directors and officers from and against any and all expenses (including attorneys' fees), liabilities and other matters and (ii) advance expenses (including attorneys' fees) incurred by any and all of its directors and officers in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative; provided, however, that, except for proceedings to enforce rights to indemnification, the Registrant shall not be obligated to indemnify any director or officer in connection with a proceeding (or part thereof) initiated by such person unless such proceeding (or part thereof) was authorized by the Board of Directors of the Registrant. The Registrant has entered into indemnification agreements with its executive officers and directors which would require it, among other things, to indemnify them against certain liabilities which may arise by reason of their status or service as a director or officer and to advance to them expenses, subject to reimbursement to the Registrant if it is determined that they are not entitled to indemnification.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director or officer of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except for liability (i) for any breach of the director's or officer's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions or (iv) for any transaction from which the director or officer derived an improper personal benefit. The Registrant's Certificate of Incorporation eliminates the personal liability of a director to the fullest extent authorized or permitted by the DGCL.

------

Under the DGCL, a Delaware corporation has the power to purchase and maintain insurance on behalf of any person who is or was director, officer, employee or agent of the corporation or is or was serving in such capacity at the request of the corporation for another enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person's status as such, whether or not the corporation would have the power to indemnify such person against such liability under the Section 145 of the DGCL. The Registrant maintains, at its expense, an insurance policy that insures the directors and officers of the Registrant, subject to certain exclusions and deductions, against certain liabilities that they may incur in their capacity as such.

Item 7. Exemption from Registration Claimed.

Not applicable.

Item 8. Exhibits.

Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Filing Fee Tables" or "Calculation of Registration Fee" table, as applicable, in the effective registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

*provided, however*, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

------

#### SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Stamford, State of Connecticut, on May 18, 2026.

| **Re:** | **Registration Statement on Form S-8** |

---

Ladies and Gentlemen:

I am the Executive Vice President, Chief Legal and Sustainability Officer, and Secretary of Hexcel Corporation, a Delaware corporation (the "Company"), and have acted as counsel in connection with the preparation of a registration statement on Form S-8 (the "Registration Statement") to be filed with the U.S. Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Act"). The Registration Statement relates to 3,015,000 shares of the Company's common stock, par value $0.01 per share (the "Shares"), to be issued from time to time pursuant to the terms of the Hexcel Corporation Long-Term Incentive Plan (the "Plan").

I have examined the Plan, the Registration Statement, the Company's Restated Certificate of Incorporation, as amended, the Company's Amended and Restated Bylaws, and such resolutions of the Company's Board of Directors and other documentation as I have deemed appropriate for the purpose of rendering this opinion.

In rendering the opinion set forth below, I have assumed the authenticity of all documents submitted to me as originals, the genuineness of all signatures and the conformity to authentic originals of all documents submitted to me as copies. I have also assumed the legal capacity for all purposes relevant hereto of all natural persons.

Based on and subject to the foregoing, I am of the opinion that the Shares to be originally issued by the Company to participants under the Plan are duly authorized and, when issued in accordance with the terms and conditions of the Plan and for such consideration as is permitted under the General Corporation Law of the State of Delaware, will be validly issued, fully paid and nonassessable.

The opinion expressed herein is limited to the General Corporation Law of the State of Delaware, as currently in effect.

I hereby consent to the filing of this opinion with the Commission as Exhibit 5.1 to the Registration Statement. In giving such consent, I do not thereby admit that I am within the category of persons whose consent is required under Section 7 of the Act or the rules or regulations of the Commission thereunder.

Very truly yours,

<u>RESTRICTED STOCK UNIT AGREEMENT</u>

for

Non-Employee Directors

RESTRICTED STOCK UNIT AGREEMENT (this "Agreement"), dated as of the Grant Date, by and between the Grantee identified on Annex A hereto and Hexcel Corpo-ra-tion (the "Company").

<u>W</u> <u>I</u> <u>T</u> <u>N</u> <u>E</u> <u>S</u> <u>S</u> <u>E</u> <u>T</u> <u>H</u>:

WHEREAS, the Company has adopted the Hexcel Corporation Long-Term Incentive Plan (the "Plan"); and

WHEREAS, the Board of Directors of the Company (the "Board") has determined that it is desirable and in the best interests of the Company to grant to the Grantee restricted stock units ("RSUs") as an incentive for the Grantee to advance the interests of the Company.

NOW, THEREFORE, the parties agree as follows:

1.&nbsp;&nbsp;&nbsp;&nbsp; <u>Notice of Grant; Incorporation of Plan</u>. Pursuant to the Plan and subject to the terms and conditions set forth herein and therein, the Company hereby grants to the Grantee the number of RSUs indicated on the Notice of Grant attached hereto as Annex A, which Notice of Grant is incorporated by reference herein. Unless otherwise provided herein, capitalized terms used herein and set forth in such Notice of Grant shall have the meanings ascribed to them in the Notice of Grant and capitalized terms used herein and set forth in the Plan shall have the meanings ascribed to them in the Plan. The Plan is incorporated by reference and made a part of this Agreement, and this Agreement shall be subject to the terms of the Plan, as the Plan may be amended from time to time, and in the event of any conflict between the terms of the Plan and this Agreement, the terms of the Plan govern. The RSUs granted herein constitute an Award within the meaning of the Plan. By accepting the Agreement, the Grantee agrees to be bound by the terms of the Plan and this Agreement and further agrees that all the decisions and determinations of the Board shall be final and binding.

2. &nbsp;&nbsp;&nbsp;&nbsp; <u>Terms of Restricted Stock Units</u>. The grant of RSUs provided in Section 1 hereof shall be subject to the following terms, conditions and restrictions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp; <u>No Ownership</u>.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Each RSU shall convert into one share of the Company's common stock, $.01 par value per share (the "Common Stock"). The Grantee shall not possess any incidents of ownership (including, without limitation, dividend and voting rights) in shares of the Common Stock in respect of the RSUs until such RSUs have vested and been distributed to the Grantee in the form of shares of Common Stock. Unless and until the RSUs have vested in the manner set forth in this Section 2, the Grantee will have no right to receive Common Stock under any such RSUs.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp; <u>Dividend Equivalents</u>. Should any cash dividends be declared and paid with respect to the shares of Common Stock during the period the RSUs are outstanding (<u>i.e.</u>, shares of Common Stock issuable under the RSUs are not issued and outstanding for purposes of entitlement to the dividend), the Company shall credit to a dividend equivalent bookkeeping account (the "Dividend Equivalent Account") the value of the dividends that would have been paid if the outstanding RSUs at the time of the declaration of the dividend were outstanding shares of Common Stock. At the same time that the corresponding RSUs are converted to shares of Common Stock and distributed to the Grantee as set forth in the earliest of Section 2(d), (e) or (f) below, the Company shall pay to the Grantee a lump sum cash payment equal to the value of the cash dividends credited to the Grantee's Dividend Equivalent Account that correspond to such RSUs; provided, however, that any dividends that were credited to the Grantee's Dividend Equivalent Account that are attributable to RSUs that have been forfeited as provided in this Agreement shall be forfeited and not payable to the Grantee. No interest shall accrue on any dividend equivalents credited to the Grantee's Dividend Equivalent Account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp; <u>Transfer of RSUs</u>. The RSUs may not be sold, assigned, transferred, pledged, hypothecated or otherwise disposed of, except by will or the laws of descent and distribution. Any attempt to transfer RSUs in contravention of this Section is void ab initio. RSUs shall not be subject to execution, attachment or other process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp; <u>Vesting and Conversion of RSUs</u>. Subject to Sections 2(e) and 2(f), the RSUs shall vest on the first to occur of (i) the first anniversary of the Grant Date, and (ii) the date immediately prior to the next Annual Meeting of Stockholders following the Grant Date (the earlier of such dates being the "Specified Date"), and shall be converted into an equivalent number of shares of Common Stock that will be immediately distributed to the Grantee within 30 days following the Specified Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp; <u>Separation from Service.</u>

(i) If the Grantee separates from service with the Company prior to the Specified Date for any reason other than death, disability or Cause, then the Grantee shall forfeit all RSUs which have not yet become vested as of the date the Grantee separated from service with the Company.

(ii) In the event the Grantee separates from service with the Company prior to the Specified Date because of the Grantee's death or disability, all RSUs shall vest, be converted into an equivalent number of shares of Common Stock and, subject to Section 2(g), be distributed to the Grantee within 30 days after the date of such separation from service (or, in the event of the Grantee's death, where additional time is needed for administrative reasons, at such later time as is permitted under Section 409A of the Code).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) In the event the Grantee separates from service with the Company for Cause, then the Grantee shall forfeit all RSUs, whether or not vested. A director will be deemed to separate from service with the
 Company for "Cause" if such separation is due to his fraud, dishonesty or intentional misrepresentation in connection with his duties as a Director or his embezzlement, misappropriation or conversion of assets or opportunities of the
 Company or any Subsidiary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) "Separation from service" (and variations thereof) shall, for all purposes of this Agreement, have the meaning given in Section 1.409A-1(h) of the Treasury Regulations (or any successor provision).

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)&nbsp;&nbsp;&nbsp;&nbsp; <u>Change in Control.</u> In the event of a Change in Control (as defined in the Plan) prior to the occurrence of the Specified Date and separation from service, all RSUs shall immediately vest, and shall be converted into shares of Common Stock and be distributed to the Grantee within 30 days after the date of the Change in Control.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) <u>Specified Employee</u>. Notwithstanding anything in Section 2(e) to the contrary, if the Grantee is a "specified employee" within the meaning of Treasury Regulation 1.409A-1(i) as of the date of his or her separation from service with the Company (as determined in accordance with the Company's policies for identifying specified employees), then no RSUs convertible on account of the Grantee's separation from service that constitute deferred compensation subject to Section 409A of the Code, shall be converted into shares of Common Stock or distributed to the Grantee until the earlier of (i) the date which is six months after the date of the Grantee's separation from service and (ii) the date of the Grantee's death.

3.&nbsp;&nbsp;&nbsp;&nbsp; <u>Taxes</u>. The Grantee shall pay to the Company promptly upon request any taxes the Company reasonably determines it is required to withhold under applicable tax laws with respect to the RSUs. Such payment shall be made as provided in Section 10.5 of the Plan.

4.&nbsp;&nbsp;&nbsp;&nbsp; <u>No Right to Continued Service as Director</u>. Nothing contained herein shall be deemed to confer upon the Grantee any right to continue to serve as a member of the Board.

5.&nbsp;&nbsp;&nbsp;&nbsp; <u>Miscellaneous</u>

(a) <u>Governing Law/Jurisdiction/Resolution of Disputes</u>. This Agreement shall be governed by and construed according to the laws of the State of Delaware, USA without regard to the conflicts of laws provisions thereof. Any disputes arising under or in connection with this Agreement shall be resolved by binding arbitration before a single arbitrator, to be held in the state of Connecticut, USA in accordance with the commercial rules and procedures of the American Arbitration Association. Judgment upon the award rendered by the arbitrator shall be final and subject to appeal only to the extent permitted by law. Each party shall bear such party's own expenses incurred in connection with any arbitration; <u>provided</u>, <u>however</u>, that the cost of the arbitration, including without limitation, reasonable attorneys' fees of the Grantee, shall be borne by the Company in the event the Grantee is the prevailing party in the arbitration. Anything to the contrary notwithstanding, each party hereto has the right to proceed with a court action for injunctive relief or relief from violations of law not within the jurisdiction of an arbitrator. If any costs of the arbitration borne by the Company in accordance herewith would constitute compensation to the Grantee for United States federal income tax purposes, then the amount of any such costs reimbursed to the Grantee in one taxable year shall not affect the amount of such costs reimbursable to the Grantee in any other taxable year, the Grantee's right to reimbursement of any such costs shall not be subject to liquidation or exchange for any other benefit, and the reimbursement of any such costs incurred by the Grantee shall be made as soon as administratively practicable, but in any event within ten (10) days, after the date the Grantee is determined to be the prevailing party in the arbitration. The Grantee shall be responsible for submitting claims for reimbursement in a timely manner to enable payment within the timeframe provided herein.

------

(b) <u>Notices</u>. Any notice required or permitted under this Agreement shall be deemed given when delivered personally, or when mailed by United States certified or registered mail, return receipt requested, postage prepaid, addressed, as appropriate, to the Grantee at the last address specified in Grantee's records with the Company, or such other address as the Grantee may designate in writing to the Company, or to the Company, Attention: Corporate Secretary, or such other address as the Company may designate in writing to the Grantee.

<br> (c) <u>Failure to Enforce Not a Waiver</u>. The failure of either party hereto to enforce at any time any provision of this Agreement shall in no way be construed to be a waiver of such provision or of any other provision hereof.

<br> (d) <u>Counterparts</u>. This Agreement may be executed in two or more counterparts, each of which shall be an original but all of which together shall represent one and the same agreement.

(e) <u>Modifications; Entire Agreement; Headings</u>. Subject to Section 6(b), any amendment to this Agreement must be in writing and, in the case of any amendment that adversely affects the Grantee's rights hereunder, such writing must be executed by the Grantee. This Agreement and the Plan contain the entire agreement between the parties relating to the subject matter hereof. This Agreement inures to the benefit of, and is binding upon, the Company and its successors-in-interest and its assigns, and the Grantee, the Grantee's heirs, executors, administrators and legal representatives. The section headings herein are intended for reference only and shall not affect the interpretation hereof.

(f) <u>Severability</u>. The provisions of this Agreement are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

<br> (g) <u>Unsecured Obligation to RSUs</u>. Prior to actual payment of any vested RSUs, such RSUs will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

(h) <u>Adjustments Upon Specified Events</u>. Upon the occurrence of certain events relating to the shares of Common Stock contemplated by Article IX of the Plan, the Administrator shall make such adjustments the Administrator deems appropriate in the number of shares of Common Stock subject to the RSUs and the kind of securities that may be issued upon settlement of the RSUs. The Grantee acknowledges that the RSUs are subject to adjustment, modification and termination in certain events as provided in this Agreement and Article IX of the Plan.

6.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Section 409A</u>.

(a) It is intended that this Agreement comply in all respects with the requirements of Section 409A of the Code and the applicable Treasury Regulations and other generally applicable guidance issued thereunder (collectively, the "Applicable Regulations"), and this Agreement shall be interpreted for all purposes in accordance with this intent.

------

(b) Notwithstanding any term or provision of this Agreement (including any term or provision of the Plan incorporated herein by reference), the parties hereto agree that, from time to time, the Company may, without prior notice to or consent of the Grantee, amend this Agreement to the extent determined by the Company, in the exercise of its discretion in good faith, to be necessary or advisable to prevent the premature inclusion in the Grantee's gross income pursuant to the Applicable Regulations of any compensation intended to be deferred hereunder. The Company shall notify the Grantee as soon as reasonably practicable of any such amendment affecting the Grantee.

(c) In the event that the amounts payable under this Agreement are subject to any taxes, penalties or interest under the Applicable Regulations, the Grantee shall be solely liable for the payment of any such taxes, penalties or interest. Although the Company intends to administer the Plan and this Agreement to prevent adverse taxation under the Applicable Regulations, the Company does not represent nor warrant that the Plan or this Agreement complies with any provision of federal, state, local or other tax law.

(d) Except as otherwise specifically provided herein, the time for distribution of the RSUs as provided in Section 2 shall not be accelerated or delayed for any reason, unless to the extent necessary to comply with or permitted under the Applicable Regulations. Further, for the avoidance of doubt, unless an election is made in accordance with the Applicable Regulations, the Grantee shall not have the right to designate the taxable year in which the RSUs shall convert into an equivalent number of shares of Common Stock and be delivered to the Grantee.

(e) <u>Modifications; Entire Agreement; Headings</u>.

<u>RESTRICTED STOCK UNIT AGREEMENT</u>

for

Non-Employee Directors

RESTRICTED STOCK UNIT AGREEMENT (this "Agreement"), dated as of the Grant Date, by and between the Grantee identified on Annex A hereto and Hexcel Corporation (the "Company").

<u>W</u> <u>I</u> <u>T</u> <u>N</u> <u>E</u> <u>S</u> <u>S</u> <u>E</u> <u>T</u> <u>H</u>:

WHEREAS, the Company has adopted the Hexcel Corporation Long-Term Incentive Plan (the "Plan");

WHEREAS, the Board of Directors of the Company (the "Board") has determined that it is desirable and in the best interests of the Company to grant to the Grantee restricted stock units ("RSUs") as an incentive for the Grantee to advance the interests of the Company; and

WHEREAS, the Grantee previously made an election to receive the Grantee's 2026 quarterly retainer fees in the form of RSUs and at the time described herein.

NOW, THEREFORE, the parties agree as follows:

1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Notice of Grant; Incorporation of Plan</u>. Pursuant to the Plan and subject to the terms and conditions set forth herein and therein, the Company hereby grants to the Grantee the number of RSUs indicated on the Notice of Grant attached hereto as Annex A, which Notice of Grant is incorporated by reference herein. Unless otherwise provided herein, capitalized terms used herein and set forth in such Notice of Grant shall have the meanings ascribed to them in the Notice of Grant and capitalized terms used herein and set forth in the Plan shall have the meanings ascribed to them in the Plan. The Plan is incorporated by reference and made a part of this Agreement, and this Agreement shall be subject to the terms of the Plan, as the Plan may be amended from time to time, and in the event of any conflict between the terms of the Plan and this Agreement, the terms of the Plan govern. The RSUs granted herein constitute an Award within the meaning of the Plan. By accepting the Agreement, the Grantee agrees to be bound by the terms of the Plan and this Agreement and further agrees that all the decisions and determinations of the Board shall be final and binding.

2.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Terms of Restricted Stock Units</u>. The grant of RSUs provided in Section 1 hereof shall be subject to the following terms, conditions and restrictions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp; <u>No Ownership</u>. Each RSU shall convert into one share of the Company's common stock, $.01 par value per share (the "Common Stock"). The Grantee shall not possess any incidents of ownership (including, without limitation, dividend and voting rights) in shares of the Common Stock in respect of the RSUs until such RSUs have been distributed to the Grantee in the form of shares of Common Stock.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp; <u>Dividend Equivalents</u>. Should any cash dividends be declared and paid with respect to the shares of Common Stock during the period the RSUs are outstanding (<u>i.e.</u>, shares of Common Stock issuable under the RSUs are not issued and outstanding for purposes of entitlement to the dividend), the Company shall credit to a dividend equivalent bookkeeping account (the "Dividend Equivalent Account") the value of the dividends that would have been paid if the outstanding RSUs at the time of the declaration of the dividend were outstanding shares of Common Stock. At the same time that the corresponding RSUs are converted to shares of Common Stock and distributed to the Grantee as set forth in the earliest of Section 2(d), (e) or (f) below, the Company shall pay to the Grantee a lump sum cash payment equal to the value of the dividends credited to the Grantee's Dividend Equivalent Account that correspond to such RSUs. No interest shall accrue on any dividend equivalents credited to the Grantee's Dividend Equivalent Account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp; <u>Transfer of RSUs</u>. The RSUs may not be sold, assigned, transferred, pledged, hypothecated or otherwise disposed of, except by will or the laws of descent and distribution. Any attempt to transfer RSUs in contravention of this Section is void ab initio. RSUs shall not be subject to execution, attachment or other process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp; <u>Vesting and Conversion of RSUs</u>. The RSUs shall be fully vested on the Grant Date and shall be converted into an equivalent number of shares of Common Stock that will be immediately distributed to the Grantee within 30 days following the first anniversary of the Grant Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp; <u>Separation from Service.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) In the event the Grantee separates from service with the Company for any reason prior to the first anniversary of the Grant Date, all RSUs shall be converted into an equivalent number of shares of Common Stock and, subject to Section 2(g),
 be distributed to the Grantee within 30 days of the date of such separation from service (or, in the event of the Grantee's death, where additional time is needed for administrative reasons, at such later time as is permitted under Section
 409A of the Code).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) "Separation from service" (and variations thereof) shall, for all purposes of this Agreement, have the meaning given in Section 1.409A-1(h) of the Treasury Regulations (or any successor provision).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)&nbsp;&nbsp;&nbsp;&nbsp; <u>Change in Control.</u> In the event of a Change in Control (as defined below) prior to the first anniversary of the Grant Date and separation from service, all RSUs shall be converted into shares of Common Stock and be distributed to the Grantee within 30 days of the date of the Change in Control.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)&nbsp;&nbsp;&nbsp;&nbsp; <u>Specified Employee</u>. Notwithstanding anything in Section 2(e) to the contrary, if the Grantee is a "specified employee" within the meaning of Treasury Regulation 1.409A-1(i) as of the date of his or her separation from service with the Company (as determined in accordance with the Company's policies for identifying specified employees), then no RSUs convertible on account of the Grantee's separation from service that constitute deferred compensation subject to section 409A of the Code shall be converted into shares of Common Stock or distributed to the Grantee until the earlier of (i) the date which is six months after the date of the Grantee's separation from service and (ii) the date of the Grantee's death.

------

3.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Taxes</u>. The Grantee shall pay to the Company promptly upon request any taxes the Company reasonably determines it is required to withhold under applicable tax laws with respect to the RSUs. Such payment shall be made as provided in Section 10.5 of the Plan.

4.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>No Right to Continued Service as Director</u>. Nothing contained herein shall be deemed to confer upon the Grantee any right to continue to serve as a member of the Board.

5.&nbsp;&nbsp;&nbsp;&nbsp; <u>Miscellaneous</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Governing Law/Jurisdiction/Resolution of Disputes</u>. This Agreement shall be governed by and construed according to the laws of the State of Delaware, USA without regard to the conflicts of laws provisions thereof. Any disputes
 arising under or in connection with this Agreement shall be resolved by binding arbitration before a single arbitrator, to be held in the state of Connecticut, USA in accordance with the commercial rules and procedures of the American
 Arbitration Association. Judgment upon the award rendered by the arbitrator shall be final and subject to appeal only to the extent permitted by law. Each party shall bear such party's own expenses incurred in connection with any arbitration; <u>provided</u>, <u>however</u>, that the cost of the arbitration, including without limitation, reasonable attorneys' fees of the Grantee, shall be borne by the Company in the event the Grantee is the prevailing party in the arbitration.
 Anything to the contrary notwithstanding, each party hereto has the right to proceed with a court action for injunctive relief or relief from violations of law not within the jurisdiction of an arbitrator. If any costs of the arbitration
 borne by the Company in accordance herewith would constitute compensation to the Grantee for United States federal income tax purposes, then the amount of any such costs reimbursed to the Grantee in one taxable year shall not affect the
 amount of such costs reimbursable to the Grantee in any other taxable year, the Grantee's right to reimbursement of any such costs shall not be subject to liquidation or exchange for any other benefit, and the reimbursement of any such costs
 incurred by the Grantee shall be made as soon as administratively practicable, but in any event within ten (10) days, after the date the Grantee is determined to be the prevailing party in the arbitration. The Grantee shall be responsible
 for submitting claims for reimbursement in a timely manner to enable payment within the timeframe provided herein.

(b) <u>Notices</u>. Any notice required or permitted under this Agreement shall be deemed given when delivered personally, or when mailed by United States certified or registered mail, return receipt requested, postage prepaid, addressed, as appropriate, to the Grantee at the last address specified in Grantee's records with the Company, or such other address as the Grantee may designate in writing to the Company, or to the Company, Attention: Corporate Secretary, or such other address as the Company may designate in writing to the Grantee.

<br> (c) <u>Failure to Enforce Not a Waiver</u>. The failure of either party hereto to enforce at any time any provision of this Agreement shall in no way be construed to be a waiver of such provision or of any other provision hereof.

------

<br> (d) <u>Counterparts</u>. This Agreement may be executed in two or more counterparts, each of which shall be an original but all of which together shall represent one and the same agreement.

(e) <u>Modifications; Entire Agreement; Headings</u>. Subject to Section 6(b), any amendment to this Agreement must be in writing and, in the case of any amendment that adversely affects the Grantee's rights hereunder, such writing must be executed by the Grantee. This Agreement and the Plan contain the entire agreement between the parties relating to the subject matter hereof. This Agreement inures to the benefit of, and is binding upon, the Company and its successors-in-interest and its assigns, and the Grantee, the Grantee's heirs, executors, administrators and legal representatives. The section headings herein are intended for reference only and shall not affect the interpretation hereof.

<br> (f) <u>Severability</u>. The provisions of this Agreement are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

<br> (g) <u>Unsecured Obligation to RSUs</u>. Prior to actual payment of any vested RSUs, such RSUs will represent an unsecured obligation of the Company, payable only from the general assets of the Company.

(h) <u>Adjustments Upon Specified Events</u>. Upon the occurrence of certain events relating to the shares of Common Stock contemplated by Article IX of the Plan, the Administrator shall make such adjustments the Administrator deems appropriate in the number of shares of Common Stock subject to the RSUs and the kind of securities that may be issued upon settlement of the RSUs. The Grantee acknowledges that the RSUs are subject to adjustment, modification and termination in certain events as provided in this Agreement and Article IX of the Plan.

6.&nbsp;&nbsp;&nbsp;&nbsp; <u>Section 409A</u>.

(a) It is intended that this Agreement comply in all respects with the requirements of Section 409A of the Code and the applicable Treasury Regulations and other generally applicable guidance issued thereunder (collectively, the "Applicable Regulations"), and this Agreement shall be interpreted for all purposes in accordance with this intent.

(b) Notwithstanding any term or provision of this Agreement (including any term or provision of the Plan incorporated herein by reference), the parties hereto agree that, from time to time, the Company may, without prior notice to or consent of the Grantee, amend this Agreement to the extent determined by the Company, in the exercise of its discretion in good faith, to be necessary or advisable to prevent the premature inclusion in the Grantee's gross income pursuant to the Applicable Regulations of any compensation intended to be deferred hereunder. The Company shall notify the Grantee as soon as reasonably practicable of any such amendment affecting the Grantee.

------

(c) In the event that the amounts payable under this Agreement are subject to any taxes, penalties or interest under the Applicable Regulations, the Grantee shall be solely liable for the payment of any such taxes, penalties or interest. Although the Company intends to administer the Plan and this Agreement to prevent adverse taxation under the Applicable Regulations, the Company does not represent nor warrant that the Plan or this Agreement complies with any provision of federal, state, local or other tax law.

(d) Except as otherwise specifically provided herein, the time for distribution of the RSUs as provided in Section 2 shall not be accelerated or delayed for any reason, unless to the extent necessary to comply with or permitted under the Applicable Regulations. Further, for the avoidance of doubt, unless an election is made in accordance with the Applicable Regulations, the Grantee shall not have the right to designate the taxable year in which the RSUs shall convert into an equivalent number of shares of Common Stock and be delivered to the Grantee.

2.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Terms of Restricted Stock Units</u>. The grant of RSUs provided in Section 1 hereof shall be subject to the following terms, conditions and restrictions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp; <u>No Ownership</u>. Each RSU shall convert into one share of the Company's common stock, $.01 par value per share (the "Common Stock").

Any attempt to transfer RSUs in contravention of this Section is void ab initio. RSUs shall not be subject to execution, attachment or other process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Vesting of RSUs</u>. The RSUs shall be fully vested on the Grant Date, and shall be converted into an equivalent number of shares of Common Stock at the time provided in Section 2(e).

5.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Miscellaneous</u>

This Agreement shall be governed by and construed according to the laws of the State of Delaware, USA without regard to the conflicts of laws provisions thereof. Any disputes
 arising under or in connection with this Agreement shall be resolved by binding arbitration before a single arbitrator, to be held in the state of Connecticut, USA in accordance with the commercial rules and procedures of the American
 Arbitration Association. Judgment upon the award rendered by the arbitrator shall be final and subject to appeal only to the extent permitted by law.

 Anything to the contrary notwithstanding, each party hereto has the right to proceed with a court action for injunctive relief or relief from violations of law not within the jurisdiction of an arbitrator. If any costs of the arbitration
 borne by the Company in accordance herewith would constitute compensation to the Grantee for United States federal income tax purposes, then the amount of any such costs reimbursed to the Grantee in one taxable year shall not affect the
 amount of such costs reimbursable to the Grantee in any other taxable year, the Grantee's right to reimbursement of any such costs shall not be subject to liquidation or exchange for any other benefit, and the reimbursement of any such costs
 incurred by the Grantee shall be made as soon as administratively practicable, but in any event within ten (10) days, after the date the Grantee is determined to be the prevailing party in the arbitration. The Grantee shall be responsible
 for submitting claims for reimbursement in a timely manner to enable payment within the timeframe provided herein.

(e) <u>Modifications; Entire Agreement; Headings</u>.

The section headings herein are intended for reference only and shall not affect the interpretation hereof.

------

<br> (f) <u>Severability</u>. The provisions of this Agreement are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

<br> (g) <u>Unsecured Obligation to RSUs</u>. Prior to actual payment of any vested RSUs, such RSUs will represent an unsecured obligation of the Company, payable only from the general assets of the Company.

(h) <u>Adjustments Upon Specified Events</u>. Upon the occurrence of certain events relating to the shares of Common Stock contemplated by Article IX of the Plan, the Administrator shall make such adjustments the Administrator deems appropriate in the number of shares of Common Stock subject to the RSUs and the kind of securities that may be issued upon settlement of the RSUs. The Grantee acknowledges that the RSUs are subject to adjustment, modification and termination in certain events as provided in this Agreement and Article IX of the Plan.

6.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <u>Section 409A</u>.

(a) It is intended that this Agreement comply in all respects with the requirements of Section 409A of the Code and the applicable Treasury Regulations and other generally applicable guidance issued thereunder (collectively, the "Applicable Regulations"), and this Agreement shall be interpreted for all purposes in accordance with this intent.

(b) Notwithstanding any term or provision of this Agreement (including any term or provision of the Plan incorporated herein by reference), the parties hereto agree that, from time to time, the Company may, without prior notice to or consent of the Grantee, amend this Agreement to the extent determined by the Company, in the exercise of its discretion in good faith, to be necessary or advisable to prevent the premature inclusion in the Grantee's gross income pursuant to the Applicable Regulations of any compensation intended to be deferred hereunder. The Company shall notify the Grantee as soon as reasonably practicable of any such amendment affecting the Grantee.

(c) In the event that the amounts payable under this Agreement are subject to any taxes, penalties or interest under the Applicable Regulations, the Grantee shall be solely liable for the payment of any such taxes, penalties or interest. Although the Company intends to administer the Plan and this Agreement to prevent adverse taxation under the Applicable Regulations, the Company does not represent nor warrant that the Plan or this Agreement complies with any provision of federal, state, local or other tax law.

(d) Except as otherwise specifically provided herein, the time for distribution of the RSUs as provided in Section 2 shall not be accelerated or delayed for any reason, unless to the extent necessary to comply with or permitted under the Applicable Regulations.
