granted to the undersigned by the resolutions adopted on [________], 2003 by the
Board of Directors of the Company, for the purpose of creating and setting forth
the terms of a series of Securities to be issued pursuant to the Indenture.
Capitalized terms not otherwise defined herein are used as defined in the
Indenture.

            1. The Board of Directors of the Company has authorized the creation
by the Company of one or more series of Securities under the Indenture through
one or more Officers' Certificates and, pursuant to such authorization and in
accordance with the Indenture, this Officers' Certificate is being delivered to
the Trustee to establish the terms of a series of Securities as set forth
therein.

            2. The title of the Securities shall be "[__]% Senior Notes due
[_____]" (herein called the "Notes").

            3. The aggregate principal amount of Notes which may be
authenticated and delivered under the Indenture is limited to U.S.$300,000,000,
except for Notes authenticated and delivered upon registration of transfer of,
or in exchange for, or in lieu of, other Notes as provided in Sections [304,
305, 306, 906, or 1106] of the Indenture, upon surrender in part of any
registered Security for conversion into other securities of the Company or
exchange for securities of another issuer pursuant to its terms, or pursuant to
or as contemplated by the terms of such Notes.

            4. The Notes shall be issuable as registered Securities and shall
not be exchangeable for bearer Securities.

            5. Subject to earlier redemption at the option of the Company, the
principal of the Notes shall be payable in U.S. dollars on [___________],
[_____].

            6. The Notes shall bear interest at the rate of [__]% per annum;
such interest shall accrue from [_______], 2003 (or from the most recent
Interest Payment Date to which interest on the Notes has been paid or provided
for); the Interest Payment Dates on which such interest shall be payable shall
be [_________] and [__________] in each year, commencing [__________], 2004; the
Regular Record Dates for the determination of Holders to whom interest is

Payment Date. Interest on the Notes shall be payable in U.S. dollars.

            7. Pursuant to the Indenture, the Trustee has been appointed as the
Security Registrar for the Notes. The Trustee is hereby further appointed as the
initial Paying Agent and transfer agent of the Notes. The principal of and
interest on the Notes shall be payable at the office of the Paying Agent, which
shall initially be located in [____________].


                                      -2-

            8. The Notes shall be redeemable at the option of the Company at any
time in whole, or from time to time in part, at a Redemption Price equal to the
greater of:

                  (i) 100% of the principal amount of the Notes being redeemed
      on the Redemption Date; or

                  (ii) the sum of the present values of the remaining scheduled
      payments of principal and interest on the Notes being redeemed on the
      Redemption Date (not including any portion of any interest payments
      accrued to the Redemption Date) discounted to the Redemption Date on a
      semi-annual basis at the Treasury Rate, as determined by the Reference
      Treasury Dealer, plus 20 basis points

plus, in each case, accrued and unpaid interest on the notes to the Redemption
Date; provided, however, that installments of interest on Notes that are due and
payable on Interest Payment Dates falling on or prior to a Redemption Date will
be payable on the Interest Payment Date to the Holders of such Notes who were
registered Holders as of the close of business on the Record Date immediately
preceding such Interest Payment Date. The Redemption Price will be calculated on
the basis of a 360-day year consisting of twelve 30-day months.

            9. The Company will not, and will not permit any Subsidiary of the
Company to, at any time, directly or indirectly, create, assume, incur or permit
to exist any Indebtedness secured by a pledge, lien or any other encumbrance on
the Common Stock of any Designated Subsidiary if the aggregate amount of the
Indebtedness so secured exceeds an amount equal to 15% of Consolidated Tangible
Net Worth, without making effective provision whereby the Notes then Outstanding
(and, if the Company so elects, any other Indebtedness of the Company that is
not subordinate to the Notes and with respect to which the governing instruments
require, or pursuant to which the Company is otherwise obligated or required, to
provide such security) shall be equally and ratably secured with such secured
Indebtedness so long as such other Indebtedness shall be secured.

            If the Company shall be required to secure the Notes equally and
ratably with any other Indebtedness pursuant to this Officers' Certificate, (i)
the Company will promptly deliver to the Trustee an Officers' Certificate
stating that the foregoing covenant has been complied with, and an Opinion of
Counsel stating that, in the opinion of such counsel, the foregoing covenant has
been complied with and that any instruments executed by the Company or any
Subsidiary of the Company in the performance of the foregoing covenant comply
with the requirements of the foregoing covenant and (ii) the Trustee is hereby
authorized to enter into an indenture or agreement supplemental hereto and to
take such action, if any, as it may deem advisable to enable it to enforce the
rights of the Holder of the Notes so secured.

            10. So long as any Notes are Outstanding and except in a transaction
otherwise permitted by the Indenture, the Company will not issue, sell, transfer
or otherwise dispose of (except to the Company, to a Subsidiary of the Company
that agrees in writing to hold such transferred shares subject to the terms of
this Officers' Certificate, or director's qualifying shares), and the Company
will not permit any Designated Subsidiary to issue, sell, transfer or


                                      -3-

otherwise dispose of (except to the Company, to a Subsidiary of the Company that
agrees in writing to hold such transferred shares subject to the terms of this
Officers' Certificate, or director's qualifying shares), any shares of capital
stock of a Designated Subsidiary (other than preferred stock having no voting
rights of any kind, except as required by law or in the event of non-payment of
dividends) in each case if, after giving effect to any such transaction, the
Company or such Designated Subsidiary, as applicable, would own, directly or
indirectly, less than 80% of the shares of the Designated Subsidiary, unless, in
each case, the capital stock of such Designated Subsidiary shall be issued,
sold, transferred or otherwise disposed of for consideration consisting of cash
or other property which, in the opinion of the Board of Directors of the Company
pursuant to a Board Resolution adopted in good faith, is at least equal to the
fair market value of such capital stock; provided, however, that the foregoing
shall not prohibit the issuance or disposition of securities if required by any
law or any regulation or order of any court or governmental or insurance
regulatory authority.

or more permanent Global Securities. The Depository Trust Company, a clearing
agency registered under the Securities Exchange Act of 1934, as amended ("DTC"),
shall initially serve as the Depositary for such Global Security or Securities.
For so long as DTC shall be the Depositary, all Notes shall be registered in its
name or in the name of a nominee thereof. While the Notes are evidenced by one
or more Global Securities, the Depositary or its nominee, as the case may be,
shall be the sole Holder thereof for all purposes under the Indenture. Neither
the Company nor the Trustee shall have any responsibility or obligation to the
Depositary's participants or the beneficial owners for whom they act with

Company within 90 days, the Company will issue individual Notes in certificated
form to owners of "book-entry" ownership interests in exchange for the Notes
held by DTC or its nominee, as the case may be. In such instance, an owner of a
"book-entry" ownership interest will be entitled to physical delivery of
certificates equal in principal amount to


                                      -6-

such "book-entry" ownership interest and to have such certificates registered in
its name. Individual certificates so issued will be issued in denominations of
U.S.$1,000 or any multiple thereof.

            18. Additional terms regarding the Notes are as set forth in the
form of the Notes set forth below.

            19. The form of the Notes shall be substantially as follows:
