Tower Group Statutory Trust V By:__________________________________ Name:_____________________________ Title: Administrator -3- [REVERSE OF SECURITY] Distributions payable on each Common Security will be payable at a fixed rate of 8.5625% (the "Fixed Rate") per annum from March 31, 2006 until April 7, 2011 (the "Fixed Rate Period") and thereafter at a variable per annum rate of interest, reset quarterly, equal to LIBOR (as defined in the Declaration) plus 3.30% (the "Variable Rate") ("Coupon Rate" is defined to include the Fixed Rate and Variable Rate, as applicable) of the stated liquidation amount of $1,000 per Capital Security, such rate being the rate of interest payable on the Debentures to be held by the Institutional Trustee. Except as set forth below in respect of an Extension Period, Distributions in arrears for more than one quarterly period will bear interest thereon compounded quarterly at the applicable Coupon Rate for each such quarterly period (to the extent permitted by applicable law). The term "Distributions" as used herein includes cash distributions, any such compounded distributions and any Additional Interest payable on the Debentures unless otherwise stated. A Distribution is payable only to the extent that payments are made in respect of the Debentures held by the Institutional Trustee and to the extent the Institutional Trustee has funds legally available in the Property Account therefor. During the Fixed Rate Period, the amount of Distributions payable for any period will be computed for any full quarterly Distribution period on the basis of a 360-day year of twelve 30-day months and the amount payable for any partial period shall be computed on the basis of the number of days elapsed in a 360-day year of twelve 30-day months. Upon expiration of the Fixed Rate Period, distribution will be computed on the basis of a 360-day year and the actual number of days elapsed in the relevant Distribution period. Except as otherwise described below, Distributions on the Common Securities will be cumulative, will accrue from the date of original issuance and will be payable quarterly in arrears on January 7, April 7, July 7 and October 7 of each year, commencing on July 7, 2006 (each, a "Distribution Payment Date"). Upon submission of Notice, the Debenture Issuer has the right under the Indenture to defer payments of interest on the Debentures by extending the interest payment period for up to 20 consecutive quarterly periods (each, an "Extension Period") at any time and from time to time on the Debentures, subject to the conditions described below, during which Extension Period no interest shall be due and payable (except any Additional Interest that may be due and payable). During any Extension Period, interest will continue to accrue on the Debentures, and interest on such accrued interest (such accrued interest and interest thereon referred to herein as "Deferred Interest") will accrue at an annual rate equal to the Coupon Rate in effect for each such Extension Period, compounded quarterly from the date such Deferred Interest would have been payable were it not for the Extension Period, to the extent permitted by law. No Extension Period may end on a date other than a Distribution Payment Date. At the end of any such Extension Period, the Debenture Issuer shall pay all Deferred Interest then accrued and unpaid on the Debentures; provided, however, that no Extension Period may extend beyond the Maturity Date. Prior to the termination of any Extension Period, the Debenture Issuer may further extend such period, provided, that such period together with all such previous and further consecutive extensions thereof shall not exceed 20 consecutive quarterly periods, or extend beyond the Maturity Date. Upon the termination of any Extension Period and upon the payment of all Deferred Interest, the Debenture -4- Issuer may commence a new Extension Period, subject to the foregoing requirements. No interest or Deferred Interest shall be due and payable during an Extension Period, except at the end thereof, but Deferred Interest shall accrue upon each installment of interest that would otherwise have been due and payable during such Extension Period until such installment is paid. If Distributions are deferred, the Distributions due shall be paid on the date that the related Extension Period terminates to Holders of the Securities as they appear on the books and records of the Trust on the record date immediately preceding such Distribution Payment Date. Distributions on the Securities must be paid on the dates payable (after giving effect to any Extension Period) to the extent that the Trust has funds legally available for the payment of such distributions in the Property Account of the Trust. The Trust's funds legally available for Distribution to the Holders of the Securities will be limited to payments received from the Debenture Issuer. The payment of Distributions out of moneys held by the Trust is guaranteed by the Guarantor pursuant to the Guarantee. The Common Securities shall be redeemable as provided in the Declaration. -5- ASSIGNMENT FOR VALUE RECEIVED, the undersigned assigns and transfers this Common Security Certificate to: _________________________ _________________________ _________________________ (Insert assignee's social security or tax identification number) _________________________ _________________________ _________________________ (Insert address and zip code of assignee), and irrevocably appoints ________ as agent to transfer this Common Security Certificate on the books of the Trust.
