        The number of ordinary shares issuable upon conversion of a particular class or series of preferred shares at any time will be the quotient obtained by dividing the aggregate conversion value of the shares of suchthe class or series surrendered for conversion by the conversion price per share of ordinary shares then in effect for suchthe class or series. ACEWe will not be required, however, upon any such conversion to issue any fractional share of ordinary shares, but instead ACEwe will pay to the holder who would otherwise be entitled to receive such fractional share, if issued,you a sum in cash equal to the value of suchthe fractional share based on the last reported sale price per ordinary share on the NYSE at the date of determination.

Theour directors, who would negotiate based upon careful consideration of the proposed terms, such asincluding the price, to be paid to shareholders, the form of consideration to be paid and the anticipated tax effects of the transaction.

This could be enable the directors to make it more difficult for someone to effect a change in control of ACE.

        The ACE debt securities of a series may be issued, in whole or in part, in the form of one or more global ACE debt securities that will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement relating to such series.

Upon the issuance of a global security, the depositary for such global security or its nominee will credit, on its book-entry registration and transfer system, the respective principal amounts of the ACE debt securities represented by such global security. Such accounts will be designated by the underwriters or agents with respect to such ACE debt securities or by ACE if such ACE debt securities are offered and sold directly by ACE. Ownership of beneficial interests in a global security will be limited to persons that may hold interests through participants. Ownership of beneficial interests in such global security will be shown on, and transfers of the transfer of that ownershipACE debt securities will be effected only through, records maintained by the depositary orand its nominee (with respect to interestsparticipants as described below.

        The specific terms of participants) and on the records of participants (with respect to interests of persons other than participants). The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form.

So long as the depositary for a global security, or its nominee, is the registered owner of such global security, such depositary or such nominee, as the case may be,arrangement will be considereddescribed in the sole owner or holderapplicable prospectus supplement.

Payment of Additional Amounts

        We will make all payments on the ACE debt securities represented by such global security for all purposes under the applicable ACE indenture. Except as described below, owners of beneficial interests in a global security will not be entitled to have ACE debt securities of the series represented by such global security registered in their names and will not receive or be entitled to receive physical delivery of ACE debt securities of that series in definitive form. Principal of, any premium and interest on, and any additional amounts with respect to, ACE debt securities registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the global security representing such ACE debt securities. None of ACE, the trustee, any paying agent or the security registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of the global security for such ACE debt securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. ACE expects that the depositary for a series of ACE debt securities or its nominee, upon receipt of any payment with respect to such ACE debt securities, will credit immediately participants' accounts with payments in amounts proportionate to their respective beneficial interest in the principal amount of the global security for such ACE debt securities as shown on the records of such depositary or its nominee. ACE also expects that payments by participants to owners of beneficial interests in such global security held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in street name, and will be the responsibility of such participants. The ACE indentures provide that if (1) the depositary for a series of ACE debt securities notifies ACE that it is unwilling or unable to continue as depositary or if such depositary ceases to be eligible under the applicable ACE indenture and a successor depositary is not appointed by ACE within 90 days of written notice, (2) ACE 25 determines that ACE debt securities of a particular series will no longer be represented by global securities and executes and delivers to the trustee a company order to such effect or (3) an Event of Default with respect to a series of ACE debt securities has occurred and is continuing, the global securities will be exchanged for ACE debt securities of such series in definitive form of like tenor and of an equal aggregate principal amount, in authorized denominations.

Global Preferred Securities

        The preferred securities of an ACE Trust may be issued, in whole or in part, in the form of one or more global preferred securities that will be deposited with, or on behalf of, the depositary. The depositary identified inand the prospectus supplement. The specific terms of the depositary arrangement with respect to the preferred securities of an ACE Trust will be described in the relatedapplicable prospectus supplement. ACE INA anticipates that the following provisions will generally apply to depositary arrangements. Upon the issuance of a global preferred security, and the deposit of such global preferred security with or on behalf of the depositary, the depositary for such global preferred security or its nominee will credit, on its book-entry registration and transfer system, the respective aggregate liquidation amounts of the individual preferred securities represented by such global preferred securities to the accounts of participants. Such accounts shall be designated by the underwriters or agents with respect to such preferred securities or by ACE INA if such preferred securities are offered and sold directly by ACE INA. Ownership of beneficial interests in a global preferred security will be limited to participants or persons that may hold interests through participants. Ownership of beneficial interests in such global preferred security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the depositary or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons who hold through participants). The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and such laws may impair the ability to transfer beneficial interests in a global preferred security. So long as the depositary for a global preferred security, or its nominee, is the registered owner of such global preferred security, such depositary or such nominee, as the case may be, will be considered the sole owner or holder of the preferred securities represented by such global preferred security for all purposes under the restated trust agreement governing such preferred securities. Except as provided below, owners of beneficial interests in a global preferred security will not be entitled to have any of the individual preferred securities represented by such global preferred security registered in their names, will not receive or be entitled to receive physical delivery of any such preferred securities in definitive form and will not be considered the owners or holders thereof under the restated trust agreement. Payments of any liquidation amount, premium or distributions in respect of individual preferred securities registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the global preferred security representing such preferred securities. None of ACE, ACE INA, the Property Trustee, any paying agent, or the securities registrar for such preferred securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of the global preferred security representing such preferred securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. ACE INA expects that the depositary or its nominee, upon receipt of any payment in respect of a global preferred security representing any ACE Trust's preferred securities, will credit immediately participants' accounts with payments in amounts proportionate to their respective beneficial interest in the aggregate liquidation amount of such global preferred security for such preferred securities as shown on the records of such depositary or its nominee. ACE INA also expects that payments by participants to owners of beneficial interests in such global preferred security held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in street name and will be the responsibility of such participants. 68 Unless otherwise specified in the applicable prospectus supplement, the restated trust agreement of each ACE Trust will provide that (1) if ACE INA advises the ACE Trustees in writing that the depositary is no longer willing or able to act as depositary and ACE fails to appoint a qualified successor within 90 days, (2) ACE INA at its option advises the ACE Trustees in writing that it elects to terminate the book-entry system through the depositary or (3) after the occurrence of an event of default under the corresponding ACE INA subordinated debt securities, owners of preferred securities representing at least a majority of liquidation amount of such preferred securities advise the Property Trustee in writing that the continuation of a book-entry system through the depositary is no longer in their best interests, then the global preferred securities will be exchanged for preferred securities in definitive form in accordance with the instructions of the depositary. It is expected that such instructions may be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in global preferred securities. Individual preferred securities so issued will be issued in authorized denominations.

Payment and Paying Agency

        Payments of distributions in respect of the preferred securities shall be made to the depositary, which shall credit the relevant accounts at the depositary on the applicable distribution dates, or,However, if any ACE Trust's preferred securities are not held by the depositary, suchthese payments shall be made by check mailed to the address of the holder entitled theretoto the payments as such addressit shall appear on the register thatof the ACE Trust.

If it is not so directed,Otherwise, the Property Trusteeproperty trustee shall take suchthe action as it deems advisable and in the best interests of the holders of the trust securities and will have no liability except for its own bad faith, negligence or willful misconduct.

ENFORCEMENT OF CIVIL LIABILITIES UNDER
UNITED STATES FEDERAL SECURITIES LAWS

        ACE is a Cayman Islands company. In addition, some of its officers and directors, as well as some of the experts named in this prospectus, reside outside the United States, and all or much of itsACE's assets and theirsome of the officers' and directors' assets are or may be located in jurisdictions outside the United States. Therefore, investors may have difficulty effecting service of process within the United States upon those persons or recovering against ACE or them on judgments of U.S. courts, including judgments based upon the civil liability provisions of the U.S. Federal securities laws. However, investors may serve ACE with process in the United States with respect to actions against it arising out of or in connection with violations of U.S. Federal securities laws relating to offers and sales of the securities covered by this prospectus by serving ACE INA Holdings, its United States agent irrevocably appointed for that purpose.

        ACE has been advised by Maples and Calder, its Cayman Islands counsel, that there is doubt as to whether the courts of the Cayman Islands would enforce (i) enforce:

        ACE has also been advised by Maples and Calder that there is no treaty in effect between the United States and the Cayman Islands providing for suchthis enforcement, and there are grounds upon which Cayman Islands courts may not enforce judgments of United States courts. Some remedies available under the laws of United States jurisdictions, including certainsome remedies available under the U.S. Federal securities laws, would not be allowed in Cayman Islands courts as contrary to that nation's public policy.

Item 15.    Indemnification of Officers and Directors.

ACE

        Section 100 of ACE's Articles of Association filed as Exhibit 4.2 to its registration statement (File No. 333-78841), contains provisions with respect to indemnification of ACE's officers and directors. This provision provides that ACE shall indemnify, in accordance with and to the full extent now or hereafter permitted by law, 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 (including, without limitation, an action by or in the right of ACE), by reason of his acting as a director, officer, employee or agent of, or his acting in any other capacity for or on behalf of, ACE against any liability or expense actually and reasonably incurred by such person in respect thereof. ACE may also advance the expenses of defending any such act, suit or proceeding in accordance with and to the full extent now or hereafter permitted by law. This indemnification and advancement of expenses are not exclusive of any other right to indemnification or advancement of expenses provided by law or otherwise.

        The Companies Law (Revised) of the Cayman Islands does not set out any specific restrictions on the ability of a company to indemnify officers or directors. However, the application of basic principles and certain Commonwealth case law which is likely to be persuasive in the Cayman Islands would indicate that indemnification is generally permissible except in the event thatif there had been fraud or willful default on the part of the officer or director or reckless disregard of his duties and obligations to the company.

        Directors and officers of ACE are also provided with indemnification against certain liabilities pursuant to a directorsdirectors' and officersofficers' liability insurance policy. Coverage is afforded for any loss that the insureds become legally obligated to pay by reason of any claim or claims first made against the insureds or any of them during the policy period from any wrongful acts that are actually or allegedly caused, committed or attempted by the insureds 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 insureds while acting in their individual or collective capacities as directors or officers of ACE, or any other matter claimed against them by reason of their being directors or officers of ACE. Certain of ACE's directors are provided by their employer with indemnification against certain liabilities incurred as directors of ACE. II-1 Reference is made to the forms of Underwriting Agreement filed as Exhibits 1.1 though 1.5 of ACE's registration statement (File No. 333-78841).

        The Underwriting Agreements which will be entered into in connection with offerings of securities registered hereunder will provide, among other things, that the underwriters are obligated, under some

II-1



circumstances, to indemnify directors, specified officers and controlling persons of ACE against specified liabilities, including liabilities under the Securities Act of 1933, as amended.

ACE INA

        Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director 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, except for liability (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts of omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for payments of unlawful dividends or unlawful stock repurchases or redemptions or (iv) for any transaction from which the director derived an improper personal benefit. ACE INA's Certificate of Incorporation contains such a provision.

        Under Article VI of ACE INA's By-laws as currently in effect, as well as under Section 10 of ACE INA's Certificate of Incorporation, each person who is or was a director or officer of ACE INA, or who serves or served any other enterprise or organization at the request of ACE INA, shall be indemnified by ACE INA to the full extent permitted by the Delaware General Corporation Law.

        Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify any person who, by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, is made (or threatened to be made) a party to an action other than one brought by or on behalf of the corporation, against reasonable expenses (including attorneys' fees), judgments, fines and settlement payments, if the person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of such corporation and, with respect to any criminal actions, also had no reasonable cause to believe his conduct was unlawful. In the case of actions on behalf of the corporation, indemnification may extend only to reasonable expenses (including attorneys' fees) and only if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, provided that no such indemnification is permitted in respect of any claim as to which such person is adjudged liable to the corporation for negligence or misconduct in the performance of his duty to the corporation unless and only to the extent that a court otherwise provides. To the extent that a person has been successful in defending any action (even one on behalf of the corporation), he is entitled to indemnification for reasonable expenses (including attorneys' fees).

        The indemnification provided for by the Delaware General Corporation Law is not exclusive of any other rights of indemnification, and a corporation may maintain insurance against liabilities for which indemnification is not expressly provided by the Delaware General Corporation Law. ACE INA maintains a liability insurance policy providing coverage for its directors and officers.

Item 17.    Undertakings.

        The undersigned registrants hereby undertake:

    (a)
    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 of 1933;

    (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 II-2 (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 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;

      (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)(i) and (a)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrants pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

    (b)
    That, for the purpose of determining any liability under the Securities Act of 1933, 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 initialbona fide offering thereof.

    (c)
    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 registrants hereby undertake that, for purposes of determining any liability under the Securities Act of 1933, each filing of ACE'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 Securities Exchange Act of 1934) 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 initialbona fide offering thereof.

        The undersigned registrants hereby undertake that:

    (a)
    For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrants pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective; and

    (b)
    For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new

II-3


      registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initialbona fide offering thereof.

        Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrants pursuant to the provisions set forth or described in Item 15 of this registration statement, or otherwise, the registrants have been informed 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 thatIf a claim for indemnification against such liabilities (other than the payment by a 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 registrants will, unless in the opinion of their counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by them is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
