BFD PREFERRED CAPITAL TRUST II By: ---------------------------- David F. Holland Administrative Trustee PROPERTY TRUSTEE'S CERTIFICATE OF AUTHENTICATION This is one of the 10.875% Capital Securities, Series B of BFD Preferred Capital Trust II referred to in the within-mentioned Declaration. Dated: , 2001 ----------------------------------------------- WILMINGTON TRUST COMPANY, not in its individual capacity but solely as Property Trustee By: Authorized Signatory 5 [FORM OF REVERSE OF SECURITY] Distributions on each Capital Security will be payable at a fixed rate per annum of 10.875% (the "Coupon Rate") of the liquidation amount of $1,000 per Capital Security, such rate being the rate of interest payable on the Debentures to be held by the Property Trustee. Distributions in arrears for more than one semi-annual period will bear interest thereon compounded semi-annually at the Coupon Rate (to the extent permitted by applicable law). Pursuant to the Registration Rights Agreement and the Liquidated Damages Agreement, in certain limited circumstances the Debenture Issuer will be required to pay Liquidated Damages (as defined in the Registration Rights Agreement and the Liquidated Damages Agreement) with respect to the Debentures. The term "Distributions," as used herein, includes such cash distributions and any and all such interest and Liquidated Damages, if any, payable unless otherwise stated. A Distribution is payable only to the extent that payments are made in respect of the Debentures held by the Property Trustee and to the extent the Property Trustee has funds legally available therefor. Distributions on the Capital Securities will be cumulative, will accumulate from the most recent date to which Distributions have been paid or, if no Distributions have been paid, from September 22, 2000 and will be payable semi-annually in arrears on April 1 and October of each year, commencing April 1, 2001 (each, a "Distribution Date"), except as otherwise described below. Distributions will be computed on the basis of a 360-day year of twelve 30-day months. As long as no Event of Default has occurred and is continuing under the Indenture, the Debenture Issuer has the right under the Indenture to defer payments of interest by extending the interest payment period at any time and from time to time on the Debentures for a period not exceeding 10 consecutive semi-annual calendar periods, including the first such semi-annual period during such extension period (each an "Extension Period"), PROVIDED THAT no Extension Period shall end on a date other than an Interest Payment Date for the Debentures or extend beyond the Maturity Date of the Debentures. As a consequence of such deferral, Distributions (other than Liquidated Damages, if any) will also be deferred. Notwithstanding such deferral, semi-annual Distributions will continue to accumulate with interest thereon (to the extent permitted by applicable law, but not at a rate exceeding the rate of interest then accruing on the Debentures) at the Coupon Rate compounded semi-annually during any such Extension Period. Prior to the termination of any Extension Period, the Debenture Issuer may further defer payments of interest by further extending such Extension Period; PROVIDED THAT such Extension Period, together with all such previous and further extensions within such Extension Period, may not (i) exceed 10 consecutive semi-annual periods, including the first semi-annual period during such Extension Period, (ii) end on a date other than an Interest Payment Date for the Debentures or (iii) extend beyond the Maturity Date of the Debentures. Payments of accumulated Distributions will be payable to Holders as they appear on the books and records of the Trust on the record date immediately preceding the end of the Extension Period. Upon the termination of any Extension Period and the payment of all amounts then due, the Debenture Issuer may commence a new Extension Period, subject to the above requirements. 6 Subject to receipt by the Sponsor of any and all required regulatory approvals and to certain other conditions set forth in the Declaration and the Indenture, the Property Trustee may, at the direction of the Sponsor, at any time dissolve the Trust and after satisfaction of liabilities to creditors of the Trust as provided by applicable law, cause the Debentures to be distributed to the Holders of the Securities in liquidation of the Trust or, simultaneously with any redemption of the Debentures, cause a Like Amount of the Securities to be redeemed by the Trust.
