Item 1.01 Entry into a Material Definitive Agreement

On March 31, 2006, Tower Group,  Inc. (the "Company")  participated in a private
placement of $20 million of fixed/floating  rate capital  securities (the "Trust
Preferred Securities") issued by Tower Group Statutory Trust V (the "Trust"), an
affiliated  Delaware  trust  formed  on March  29,  2006.  The  Trust  Preferred
Securities  mature in April 2036, are redeemable at the Company's  option at par
beginning April 7, 2011, and require quarterly  distributions of interest by the
Trust  to the  holder  of the  Trust  Preferred  Securities.  Distributions  are
initially  at a fixed  rate of  8.5625%  for the first  five years and will then
reset quarterly for changes in the  three-month  London  Interbank  Offered Rate
("LIBOR") rate plus 330 basis points. The Trust simultaneously issued 619 of the
Trust's common securities to the Company for a purchase price of $619,000, which
constitutes all of the issued and outstanding common securities of the Trust.

The Trust used the proceeds from the sale of the Trust  Preferred  Securities to
purchase for  $20,000,000  a Junior  Subordinated  Debt Security due 2036 in the
principal amount of $20,000,000  issued by the Company.  The net proceeds to the
Company from the sale of the  Debenture to the Trust will be used by the Company
to acquire and capitalize a shell insurance  company with multi-state  licensing
and for working capital purposes.  There is no assurance that the acquisition of
a shell insurance company will be completed.

The Debenture was issued  pursuant to an Indenture  dated March 31, 2006, by and
between the Company and Wells Fargo Bank, National Association , as trustee. The
terms of the  Debenture  are  substantially  the same as the  terms of the Trust
Preferred  Securities.  The interest payments by the Company will be used by the



Trust to pay the quarterly  distributions  to the holders of the Trust Preferred
Securities.  The Indenture permits the Company to redeem the Debenture (and thus
a like amount of the  Preferred  Trust  Securities)  after April 7, 2011. If the
Company redeems any amount of its Debenture, the Trust must redeem a like amount
of the Trust Preferred Securities.

The terms of the Trust  Preferred  Securities  are  governed  by an Amended  and
Restated  Declaration  of Trust,  dated March 31, 2006, by and among Wells Fargo
Bank, National Association, as Institutional Trustee; Wells Fargo Delaware Trust
Company,  as Delaware  Trustee;  Tower  Group,  Inc,  as Sponsor;  and the Trust
Administrators,  Francis M.  Colalucci and Steve G. Fauth.  The Company,  as the
sole holder of the  Trust's  Common  Securities,  controls  the  election of the
trustee and administrators.  Under the terms of the Trust Preferred  Securities,
an event of default may occur upon:

o    non-payment  of interest  on the Trust  Preferred  Securities,  unless such
     non-payment is due to a valid extension of an interest payment period;

o    non-payment  of all of any part of the  principal  of the  Trust  Preferred
     Securities;

o    the Company's  failure to comply with the covenants or other  provisions of
     the indentures or the Trust Preferred Securities; or

o    bankruptcy or liquidation of the Company or of the Trust.

Pursuant to a Guarantee  Agreement  dated March 31, 2006,  by and between  Tower
Group,  Inc.  and Wells  Fargo  Delaware  Trust  Company,  Tower  has  agreed to
guarantee the payment of distributions and payments on liquidation or redemption
of the Trust Preferred Securities,  but only in each case to the extent of funds



held by the Trust. The obligations of the Company under the Guarantee  Agreement
and the Trust  Preferred  Securities  are  subordinate  to all of the Company 's
senior and subordinated debt.

The  offering of the Trust  Preferred  Securities  was  conducted  pursuant to a
Purchase  Agreement  dated  March 29,  2006  amongst  the  Company,  Tower Group
Statutory Trust V and Bear Stearns & Company,  Inc.  Cochran Colonia Waller LLC,
the  introducing  agent,  received a commission  of two percent of the principal
amount of the Debenture.
