With respect to the Senior Notes being issued or sold to "qualified institutional buyers" (as defined in Rule 144A under the Securities Act ("Rule 144A"), the Depositary will issue one or more global receipts representing a 100% interest in the underlying Restricted Global Note (the "Restricted Global Receipts", and together with the Regulation S Global Receipts, the "Global Receipts"), which will be delivered and registered in the name of DTC or its nominee pursuant to the terms of the Deposit and Custody Agreement. (b) Restrictive Legends. Unless and until a Senior Note is exchanged ------------------- for an Exchange Note in connection with an effective Exchange Registration pursuant to the Registration Rights Agreement and except as provided in Section 2.8, the Restricted Global Note and each Restricted Definitive Senior Note shall bear the following legend (the "Private Placement Legend") on the face thereof: THIS SENIOR NOTE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DE- FINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS SENIOR NOTE IN AN OFFSHORE 26 TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, (2) AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS SENIOR NOTE EXCEPT, (A) TO BERMUDA HOLDINGS OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, OR (D) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS SENIOR NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. [WITH RESPECT TO ANY RESTRICTED DEFINITIVE SENIOR NOTE: IN CONNECTION WITH ANY TRANSFER OF THIS SENIOR NOTE WITHIN THE TIME PERIOD REFERRED TO ABOVE, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THE CERTIFICATE TO THE TRUSTEE ON THE REVERSE HEREOF.] AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION", "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS SENIOR NOTE IN VIOLATION OF THE FOREGOING RESTRICTIONS. Section 2.2 Execution and Authentication. Two directors, or a ---------------------------- director and the Secretary, shall sign the Senior Notes for the Issuer by manual or facsimile signature. Two directors, or a director and the Secretary, shall sign the notation of Guarantee, to be endorsed on the Senior Notes by Bermuda Holdings, for Bermuda Holdings by manual or facsimile signature. The signatures required hereby may in 27 each case be the manual signature of any person duly delegated by a director or the Secretary, as the case may be. If an officer (including a director, Secretary or Assistant Secretary) whose signature is on a Senior Note no longer holds that office at the time the Trustee authenticates the Senior Note, the Senior Note shall be valid nevertheless. A Senior Note shall not be valid until an authorized officer of the Trustee manually signs the certificate of authentication on the Senior Note. The signature shall be conclusive evidence that the Senior Note has been authenticated under this Indenture. The Trustee shall authenticate and deliver the (a) Global Notes for - original issue in an aggregate principal amount at maturity not in excess of $75,000,000, and (b) Exchange Notes for issue only in an Exchange Offer pursuant to the Registration Rights Agreement, for a like principal amount of Global Notes exchanged pursuant thereto, in each case upon a written order signed by a director or Secretary of the Issuer and a director or Assistant Secretary of Bermuda Holdings. Such order shall specify the principal amount of the Global Notes to be authenticated and the date on which the original issue of the Global Notes are to be authenticated and shall further provide instructions concerning delivery of the Global Notes. The aggregate principal amount of Senior Notes outstanding at any time may not exceed that amount, except as provided in Section 2.7 hereof. Each Global Note shall be dated the date of its authentication, shall bear interest from the applicable date and shall be payable on the dates specified on the face of the form of Global Notes set forth as Exhibit A and Exhibit B hereto. Each Definitive Senior Note shall be dated the date of its authentication, shall bear interest from the applicable date and shall be payable on the dates specified on the face of the form of Definitive Senior Note set forth in Exhibit C hereto. The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer and Bermuda Holdings to authenticate the Senior Notes. Unless limited by the terms of such appointment, an authenticating agent may authenticate Senior Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Senior Note Registrar or Paying Agent. Section 2.3 Senior Note Registrar and Paying Agent. The Issuer will -------------------------------------- maintain in the City of New York, an office or agency where Senior Notes may be presented or surrendered for payment (the "Paying Agent"), where Senior Notes may 28 be surrendered for registration of transfer or exchange (the "Senior Note Registrar") and where notices and demands to or upon the Issuer in respect of the Senior Notes and this Indenture may be served. Until otherwise designated by the Issuer, such office or agency in The City of New York shall be the office maintained by the Trustee for such purpose. The Issuer will give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office, and the Issuer hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. The Issuer may from time to time designate one or more other offices or agencies (in or outside The City of New York) where the Senior Notes may be presented or surrendered for any or all such purposes, and may from time to time rescind such designation; provided, however, that no such designation or rescission shall in any manner relieve the Issuer of its obligation to maintain an office or agency in The City of New York for such purposes. The Issuer will give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such office or agency. The Issuer shall enter into an appropriate agency agreement with any Senior Note Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the Trust Indenture Act. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee of the name and address of any such agent. The Issuer may change any Paying Agent, Senior Note Registrar, co- registrar or transfer agent without prior notice to any holder of Senior Notes. If the Issuer fails to maintain a Senior Note Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 5.6. The Issuer initially appoints the Trustee as Senior Note Registrar and Paying Agent in connection with the Senior Notes. Section 2.4 Paying Agent To Hold Money in Trust. If the Issuer shall ----------------------------------- at any time act as its own Paying Agent, it will, by 10:00 a.m. (New York City time) on or before each due date of the principal of and any premium and interest on the Senior Notes (and any Additional Amounts payable by the Issuer or Bermuda Holdings in respect thereof), segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest on the Senior Notes (and any Additional Amounts payable by the Issuer or Bermuda Holdings in 29 respect thereof) so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and will promptly notify the Trustee of its action or failure so to act. Whenever the Issuer shall have one or more Paying Agents for the Senior Notes, it will, at least one Business Day before such due date of the principal of and any premium and interest on the Senior Notes (and any Additional Amounts payable by the Issuer or Bermuda Holdings in respect thereof), deposit with a Paying Agent a sum in same day funds (or New York Clearing House funds if such deposit is made prior to the date on which such deposit is required to be made) sufficient to pay the principal and any premium and interest to become due on the Senior Notes (and any Additional Amounts payable by the Issuer or Bermuda Holdings in respect thereof), such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest on the Senior Notes and (unless such Paying Agent is the Trustee) the Issuer will promptly notify the Trustee of such action or any failure so to act. The Issuer will cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: (a) hold all sums held by it for the payment of the principal of and any premium and interest on the Senior Notes (and any Additional Amounts payable by the Issuer or Bermuda Holdings in respect thereof) in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; (b) give the Trustee notice of any default by the Issuer or Bermuda Holdings (or any other obligor upon the Senior Notes) in the making of any payment of principal and any premium and interest on the Senior Notes (and any Additional Amounts payable by the Issuer or Bermuda Holdings in respect thereof); (c) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent; and (d) acknowledge, accept and agree to comply in all respects with the provisions of this Indenture relating to the duties, rights and obligations of such Paying Agent. 30 The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by an order of the Issuer direct any Paying Agent to pay, to the Trustee all sums held in trust by the Issuer or such Paying Agent, such sums to be held by the Trustee upon the same terms as those upon which such sums were held by the Issuer or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of and any premium and interest on the Senior Notes (and any Additional Amounts payable by the Issuer or Bermuda Holdings in respect thereof) and remaining unclaimed for two years after such principal and any premium and interest on the Senior Notes (and any Additional Amounts payable by the Issuer or Bermuda Holdings in respect thereof) has become due and payable shall be paid to the Issuer or Bermuda Holdings upon Request by the Issuer or Bermuda Holdings, as the case may be; and the Holder of such Senior Note shall thereafter, as an unsecured general creditor, look only to the Issuer or Bermuda Holdings for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer or Bermuda Holdings. Section 2.5 Senior Note Holder Lists. The Trustee, or such other ------------------------ person designated by the Issuer, shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders of Definitive Senior Notes, if any (the "Senior Note Register"). If the Trustee is not the Senior Note Registrar, the Issuer or Bermuda Holdings shall furnish to the Trustee, in writing on or before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of Definitive Senior Notes, if any. Section 2.6 Transfer and Exchange. The Global Notes shall be --------------------- exchanged by the Issuer (with authentication by the Trustee) for one or more Definitive Senior Notes, if (i) the Custodian notifies the Issuer, Bermuda - Holdings and the 31 Trustee that it is unwilling or unable to continue as Custodian and no successor Custodian has been appointed by the Issuer within 90 days of such notification, (ii) the Depositary notifies the Issuer, Bermuda Holdings and the Trustee that -- it is unwilling or unable to continue as Depositary and no successor Depositary has been appointed by the Issuer or Bermuda Holdings within 90 days of such notification, (iii) DTC notifies the Issuer, Bermuda Holdings and the Depositary --- that it is unwilling or unable to continue as holder with respect to the Global Receipts or if at any time it ceases to be a clearing agency under the Exchange Act and, in either case, a successor to DTC registered as a clearing agency under the Exchange Act is not appointed by the Issuer or Bermuda Holdings within 90 days of such notification, (iv) the Issuer or Bermuda Holdings determines -- that Definitive Senior Notes shall be issued, or (v) the Holder requests the - issuance of Definitive Senior Notes after the occurrence of an Event of Default; provided, however, that no Regulation S Definitive Senior Note may be issued prior to October 6, 1997. Members of, or participants in, the DTC ("Agent Members") shall have no rights under this Indenture with respect to any Global Receipt held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Receipt, and the Depositary may be treated by the Issuer, Bermuda Holdings, the Trustee and any agent of the Issuer, Bermuda Holdings, or the Trustee as the absolute owner of such Global Receipt for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, Bermuda Holdings, the Trustee or any agent of the Issuer, Bermuda Holdings or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Senior Note. Whenever all of a Global Note is exchanged for one or more Definitive Senior Notes, such Global Note shall be surrendered by the Holder thereof to the Trustee for cancellation. Whenever a part of the Global Notes is exchanged for one or more Definitive Senior Notes (which shall be in denominations of $1,000 or integral multiples thereof), the Global Note shall be surrendered by the Holder thereof to the Trustee who shall cause an adjustment to be made to such Global Note such that the principal amount of such Global Notes will be equal to the portion of such Global Notes not exchanged and shall thereafter return such Global Notes to such Holder. Definitive Senior Notes issued in exchange for the Global Notes or any portion thereof shall be registered in such names as the Depositary shall instruct the Trustee based on the instructions of DTC, as requested by the Issuer. The Global Notes may not be exchanged other than as provided in this Section 2.6. 32 Definitive Senior Notes shall be transferable only upon the surrender of a Definitive Senior Note for registration of transfer. When a Definitive Senior Note is presented to the Senior Note Registrar or a co-registrar with a request to register a transfer, the Senior Note Registrar shall register the transfer as requested if its re quirements for such transfers are met. When Definitive Senior Notes are presented to the Senior Note Registrar or a co- registrar with a request to exchange them for an equal principal amount of Definitive Senior Notes of other denominations, the Senior Note Registrar shall make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Definitive Senior Notes at the Senior Note Registrar's or co-registrar's request. The Holder of the Global Note may increase the principal amount of the Global Note held by it by surrendering any Definitive Senior Note registered in its name to the Senior Note Registrar for cancellation, provided that no Definitive Senior Note shall be so surrendered during the period beginning on the Record Date and ending on the corresponding Interest Payment Date. Upon surrender of such Definitive Senior Note, the Senior Note Registrar shall forward such Definitive Senior Note to the Trustee for cancellation and the Trustee shall cause an adjustment to be made to such Global Note to increase the principal amount at maturity of such Global Note by an amount equal to the principal amount at maturity of the Definitive Senior Note surrendered for cancellation. The Issuer shall not be required to make and the Senior Note Registrar need not register transfers or exchanges of Definitive Senior Notes selected for redemption (except, in the case of Definitive Senior Notes to be redeemed in part, the portion thereof not to be redeemed) or any Definitive Senior Notes for a period of 15 days before a selection of Definitive Senior Notes to be redeemed. Prior to the due presentation for registration of transfer of any Definitive Senior Note, the Issuer, the Trustee, the Paying Agent, the Senior Note Registrar or any co-registrar shall deem and treat the person in whose name a Definitive Senior Note is registered as the absolute owner of such Definitive Senior Note for the purpose of receiving payment of principal of and interest on such Definitive Senior Note and for all other purposes whatsoever, whether or not such Definitive Senior Note is overdue, and none of the Issuer, the Trustee, the Paying Agent, the Senior Note Registrar or any co-registrar shall be affected by notice to the contrary. 33 The Issuer may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section 2.6. All Senior Notes issued upon any transfer or exchange pursuant to the terms of this Indenture will evidence the same debt and will be entitled to the same benefits under this Indenture as the Senior Notes surrendered upon such transfer or exchange. Section 2.7 Replacement Securities. If a mutilated Definitive Senior ---------------------- Note is surrendered to the Senior Note Registrar, if a mutilated Global Note is surrendered to the Issuer, or if the Holder of a Senior Note claims that the Senior Note has been lost, destroyed or wrongfully taken, the Issuer shall issue, and the Trustee shall authenticate, a replacement Senior Note in such form as the Senior Note mutilated, lost, destroyed or wrongfully taken, if the Holder satisfies any reasonable requirements of the Trustee, the Senior Note Registrar or the Issuer. If required by the Trustee, the Senior Note Registrar or the Issuer, such Holder shall furnish an indemnity bond sufficient in the judgment of the Issuer, the Senior Note Registrar and the Trustee to protect the Issuer, Bermuda Holdings, the Trustee, the Paying Agent, the Senior Note Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The Issuer, the Senior Note Registrar and the Trustee may charge the Holder for their expenses in replacing a Senior Note. Every replacement Senior Note is an additional obligation of the Issuer. Section 2.8 Outstanding Securities. If a Senior Note is replaced ---------------------- pursuant to Section 2.7 hereof, it ceases to be Outstanding unless the Trustee and the Issuer receive proof satisfactory to them that the replaced Senior Note is held by a bona fide purchaser. If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date, money sufficient to pay all principal and interest payable on that date with respect to the Senior Notes (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Senior Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue, as the case may be. Section 2.9 Temporary Senior Notes. Until Definitive Senior Notes ---------------------- are ready for delivery, the Issuer and Bermuda Holdings may prepare and the Trustee shall authenticate temporary Senior Notes. Temporary Senior Notes shall be substantially in 34 the form of Definitive Senior Notes but may have variations that the Issuer and Bermuda Holdings consider appropriate for temporary Senior Notes. Without unreasonable delay, the Issuer and Bermuda Holdings shall prepare and the Trustee shall authenticate Definitive Senior Notes and deliver them in exchange for temporary Senior Notes. Section 2.10 Cancellation. The Issuer at any time may deliver Senior ------------ Notes to the Trustee for cancellation. The Senior Notes Registrar and the Paying Agent shall forward to the Trustee any Senior Notes surrendered to them for registration of transfer, exchange, purchase or payment. The Trustee (and no one else) shall cancel all Senior Notes surrendered for registration of transfer, exchange, purchase, payment or cancellation and shall dispose of cancelled Senior Notes as the Issuer directs. The Issuer may not issue new Senior Notes to replace Senior Notes it has redeemed, paid or delivered to the Trustee for cancellation. The Trustee shall not authenticate Senior Notes in place of cancelled Senior Notes other than pursuant to the terms of this Indenture. Section 2.11 Interest; Defaulted Interest. Interest on the Senior ---------------------------- Notes shall accrue from August 26, 1997 at the rate set forth in Exhibit A, Exhibit B and Exhibit C. If the Issuer defaults in a payment of interest on the Senior Notes, the Issuer shall pay defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Issuer may pay the defaulted interest in the case of a Global Note, to the Trustee, which shall, in accordance with Section 3.01 of the Deposit and Custody Agreement, distribute such payments, on behalf of the Custodian and the Depositary to DTC or its nominee, and in the case of any Definitive Senior Note, to the Holder of such Definitive Senior Note on a subsequent Special Record Date. The Issuer shall fix or cause to be fixed any such Special Record Date and payment date and shall promptly mail to each holder of Senior Notes and the Trustee a notice that states the special record date, if any, the payment date and the amount of defaulted interest to be paid. The Issuer may make payment of any defaulted interest in any other lawful manner not inconsistent with the requirements (if applicable) of any securities exchange on which the Senior Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuer to the Trustee of the proposed payment pursuant to this paragraph, such manner of payment shall be deemed practicable by the Trustee.
