**Item 4.** **Description of Securities**

Not applicable.

**Item 5.** **Interests of Named Experts and Counsel**

Not applicable.

**Item 6.** **Indemnification of Directors and Officers**

It is generally permissible under Swiss law to agree in a fiduciary agreement to hold a board member harmless for any liabilities that he or she is confronted with during his or her term of office, save for gross negligence, willful intent, contradictory action with regard to legitimate instructions, or in respect to the violation of certain corporate law duties. Swiss law permits the Registrant or each board member or officer individually to purchase and maintain insurance for directors and officers. The coverage of such insurance depends on the individual insurance policy.

The Chubb board members as well as the officers of Chubb are jointly and severally liable to Chubb, the shareholders and the creditors for damage caused by violation of their duties.

A resolution passed at the shareholders' meeting discharging the members of the Chubb Board of Directors for statutory liability covers only matters that have been disclosed to the shareholders' meeting and is binding only upon Chubb and upon shareholders that have approved the resolution. The right of the remaining shareholders to claim damages on behalf of Chubb expires 12 months after such resolution has been passed.

Chubb's Articles of Association and Organizational Regulations provide that Chubb will indemnify and hold harmless, to the fullest extent permitted by law, each of the current or former members of the Chubb Board of Directors and officers out of Chubb's assets from and against all actions, costs, charges, losses, damages and expenses which they or any of them may incur or sustain by or by reason of any act done, concurred in or omitted in or about the execution of their duty, or supposed duty on behalf of Chubb; provided that this indemnity shall not extend to any matter in which any of said persons is found, in a final judgment or decree not subject to appeal, to have committed fraud or dishonesty. Without limiting the foregoing, Chubb shall advance court costs and attorney's fees to the current or former members of the Chubb Board of Directors and officers, except in cases where Chubb itself is the plaintiff. Chubb may, however, recover such advanced costs if a court holds that the Chubb director or the officer in question has breached relevant duties.

Chubb has entered into indemnification agreements with its directors and executive officers. The indemnification agreements are in furtherance of Chubb's Articles of Association, which require the Registrant to indemnify its directors and officers to the fullest extent permitted by applicable law, as well as New York Stock Exchange and Securities and Exchange Commission regulations. The indemnification agreements provide for indemnification arising out of specified indemnifiable events and provide for advancement of expenses. The indemnification agreements set forth procedures relating to indemnification claims.

Chubb maintains directors' and officers' insurance for its directors and officers, pursuant to a directors' and officers' liability insurance policy. Coverage is afforded for any loss that the insured persons become legally obligated to pay by reason of any claim or claims first made against the insured persons or any of them during the policy period from any wrongful acts that are actually or allegedly caused, committed or attempted by the insured persons prior to the end of the policy period. Wrongful acts are defined as any actual or alleged error, misstatement, misleading statement or act, omission, neglect or breach of duty by the insured persons while acting in their individual or collective capacities as directors or officers of Chubb, or any other matter claimed against them by reason of their being directors or officers of Chubb. Certain of Chubb's directors may also be provided by their employer with indemnification against certain liabilities incurred as directors of Chubb.

**Item 7.** **Exemption from Registration Claimed**

Not applicable.

**Item 8.** **Exhibits**

**Item 9.** **Undertakings.**

The undersigned Registrant hereby undertakes:

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

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

(ii) To reflect in the prospectus any facts or events arising after the effective date of this 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 this Registration Statement. Notwithstanding the foregoing, any increase or decrease in the 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 a 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

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

*provided, however,* paragraphs (1)(i) and (ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Securities and Exchange Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement.

(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.

(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.

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 15(d) of the Securities Exchange Act of 1934 (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 this 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.

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 Securities and Exchange 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**

Each person whose signature appears below constitutes and appoints Evan G. Greenberg, Peter C. Enns and Joseph F. Wayland, and each of them, the true and lawful attorneys-in-fact and agents of the undersigned, with full power of substitution and resubstitution, for and in the name, place and stead of the undersigned, in any and all capacities, to sign any and all amendments (including post-effective amendments) to this Registration Statement, and to file the same, with all exhibits thereto, and other documents in connection therewith, with the Securities and Exchange Commission, and hereby grants to such attorneys-in-fact and agents, and each of them, full power and authority to do and perform each and every act and thing requisite and necessary to be done, full to all intents and purposes as the undersigned might or could do in person, hereby ratifying and confirming all that said attorneys-in-fact and agents, or any of them, or their or his or her substitute or substitutes, may lawfully do or cause to be done by virtue hereof.

Pursuant to the requirements of the Securities Act, 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 New York, New York, on May 27, 2026.

Dear Sir or Madam,

We have been asked to issue a legal opinion letter as special Swiss legal counsel of Chubb Limited, Bärengasse 32, CH-8001 Zurich, Switzerland, Swiss business identification number CHE-114.425.464 (the "**Company**") in connection with the registration statement on Form S-8 (the "**Registration Statement**"), being filed with the Securities and Exchange Commission (the "**Commission**") under the United States Securities Act of 1933, as amended (the "**Act**"), for the registration of common shares of the Company with a par value of CHF 0.50 each (the "**Shares**") issuable in connection with the Chubb Limited 2016 Long-Term Incentive Plan, as amended and restated, and approved by the Company's shareholders at the Company's annual general meeting on 21 May 2026 (the "**Amended LTIP**").

The Registration Statement covers 12,300,000 Shares, subject to adjustment as set forth in Section 4.2(g) of the Amended LTIP (the "**Registered Shares**").

Bär & Karrer 27 May 2026 2

**I** **Documents**

In arriving at the opinions expressed in section III below, we have exclusively reviewed and relied on the following documents, the sufficiency of which we confirm for purposes of this legal opinion letter (the documents referred to in this clause I collectively the "**Documents**" and any individual document thereof a "**Document**"):

&nbsp;&nbsp;&nbsp;&nbsp;a) an excerpt from the commercial register
 of the Canton of Zurich, Switzerland, in relation to the Company, certified by said register
 to be up-to-date as of 22 May 2026;

&nbsp;&nbsp;&nbsp;&nbsp;b) a copy of the articles of association of
 the Company, certified by the commercial register of the Canton of Zurich, Switzerland, to
 be up-to-date as deposited with such register as of 22 May 2026 (the "**Articles** ");

 the Company dated 27 May 2026 on the amount of Conditional Capital of the Company.

**II** **Assumptions**

In arriving at the opinions expressed in section III below, we have assumed (without verification) cumulatively that:

&nbsp;&nbsp;&nbsp;&nbsp;a) the information set out in the Documents
 and in the Instructions is true, accurate, complete and up-to-date as of the date of this
 legal opinion letter and no changes have been made or will be made that should have been
 or should be reflected in the Documents as of the date of this legal opinion letter;

&nbsp;&nbsp;&nbsp;&nbsp;b) the Documents submitted to us as (hard
 or electronic) copies are complete and conform to the original document;

&nbsp;&nbsp;&nbsp;&nbsp;c) all signatures and seals on any Document
 are genuine;

&nbsp;&nbsp;&nbsp;&nbsp;d) where a name is indicated (in print or
 in handwriting) next to a signature appearing on any Document, the signature has been affixed

 next to a signature appearing on any Document, the relevant Documents have been duly signed

Bär & Karrer 27 May 2026 3

&nbsp;&nbsp;&nbsp;&nbsp;e) the Board has not, and will not, authorize
 the issuance of any other options that are to be sourced from Conditional Capital and that,
 together with the New Shares, exceed the amount of Conditional Capital;

&nbsp;&nbsp;&nbsp;&nbsp;f) the Board will not cancel the provisions
 on Conditional Capital from the Articles;

&nbsp;&nbsp;&nbsp;&nbsp;g) to the extent any authorizations, approvals,
 consents, licenses, exemptions or other requirements (collectively the "**Authorizations** ")

 Treasury Shares and the issuance of the New Shares, such Authorizations have been obtained
 or fulfilled or will be obtained or fulfilled in due time, and have remained or will remain
 in full force and effect at all times through re-use of the Treasury Shares and the issuance
 of the New Shares;

&nbsp;&nbsp;&nbsp;&nbsp;h) the Company is not listed in Switzerland;

&nbsp;&nbsp;&nbsp;&nbsp;i) to the extent agreements or documents have
 to be executed or any obligations have to be performed under applicable laws other than Swiss
 law or in any jurisdiction outside Switzerland, such execution or performance will not be
 illegal or unenforceable by virtue of the laws of such jurisdiction; and

&nbsp;&nbsp;&nbsp;&nbsp;j) the Company will not pass a voluntary winding-up
 resolution, no petition will be presented or order made by a court for the winding-up, dissolution,
 bankruptcy or administration of the Company, and no receiver, trustee in bankruptcy, administrator
 or similar officer will have been appointed in relation to the Company or any of its assets
 or revenues between the date of this legal opinion letter and the date of the issuance of
 the New Shares.

**III** **Opinion**

Based upon the foregoing, and subject to the qualifications and reliance limitations set out in section IV and section V below, we are of the opinion that under the laws of Switzerland as currently in force and interpreted:
