                          TRENWICK AMERICA CORPORATION
              Notes to Unaudited Consolidated Financial Statements
   (Amounts expressed in thousands of United States dollars except share data)
                Three and Six Months Ended June 30, 2001 and 2000


Note 1     Organization and Basis of Presentation

Organization

     Trenwick  America  Corporation  is a United  States  holding  company whose
     principal  subsidiaries  underwrite  specialty  insurance and  reinsurance.
     Trenwick  America  Corporation's  ultimate  parent is Trenwick  Group Ltd.,
     which is a publicly traded Bermuda holding  company.Prior  to September 27,
     2000, Trenwick America Corporation's parent was Trenwick Group Inc.

     On  September  27,  2000,  Trenwick  Group Ltd.,  a newly  formed  company,
     acquired all of the assets and  liabilities  of Trenwick Group Inc. and all
     of the issued and outstanding  common shares of LaSalle Re Holdings Limited
     and LaSalle Re Limited in exchange for Trenwick  Group Ltd.  common shares.
     Trenwick  Group Inc.  then  distributed  the shares  received from Trenwick
     Group Ltd. to its shareholders in a liquidating distribution. Substantially
     all of Trenwick Group Inc.'s assets and liabilities  were  transferred from
     Trenwick  Group  Inc.  to  Chartwell  Re  Holdings   Corporation   (then  a
     wholly-owned  subsidiary of Trenwick Group Inc.)  immediately  prior to the
     Trenwick/LaSalle  business  combination.  Chartwell Re Holdings Corporation
     then sold most of its United Kingdom and Bermuda  subsidiaries  to Trenwick
     Group Inc. at fair value.  Immediately after the Trenwick/LaSalle  business
     combination,  Chartwell  Re  Holdings  Corporation  merged  with  and  into
     Trenwick  America  Corporation,  with Trenwick  America  Corporation as the
     surviving  corporation.  As a  result  of  such  merger,  Trenwick  America
     Corporation acquired Chartwell Insurance Company, The Insurance Corporation
     of New York and Dakota Specialty  Insurance Company.  The  Trenwick/LaSalle
     business  combination  and  its  related  transactions  were  completed  on
     September 27, 2000.

Basis of Presentation

     The business  combination  among  LaSalle Re Holdings  Limited,  LaSalle Re
     Limited, Trenwick Group Inc. and Trenwick Group Ltd. was accounted for as a
     purchase by LaSalle Re Holdings Limited of the minority interest in LaSalle
     Re  Limited  and  of  Trenwick  Group  Inc.  Accordingly,  the  assets  and
     liabilities of Trenwick  America  Corporation have been adjusted to reflect
     their  fair  value,  after  consideration  of  the  purchase  price,  as of
     September 27, 2000. In addition,  a portion of the goodwill  resulting from
     the  business   combination  has  been  pushed  down  to  Trenwick  America
     Corporation  and was  reflected  in the  consolidated  balance  sheet as of
     September  27,  2000.  During the three  months  ended March 31,  2001,  an
     additional  $2.0  million of goodwill  was pushed down to Trenwick  America
     Corporation  due to the refinement of estimates used in the  calculation of
     goodwill resulting from this business combination.

     As a result of the  reorganization  described above, the United Kingdom and
     Bermuda  subsidiaries  of Trenwick  Group Inc. were sold to Trenwick  Group
     Ltd., and the remaining net liabilities of Trenwick Group Inc.,  consisting
     primarily of indebtedness and preferred capital securities, were assumed by
     Trenwick  America  Corporation.  These  financial  statements  present  the
     reorganization  at  historical  cost in a manner  similar  to a pooling  of
     interests  business  combination.  Accordingly,  the  accompanying  interim
     financial  statements for the three and six months ended June 30, 2000 have
     been restated to reflect the combined  operating  results,  cash flows, and
     financial position of the United States operations of Trenwick Group Inc.


                                       -4-



     The interim financial  statements  include the accounts of Trenwick America
     Corporation  and  its   subsidiaries   after   elimination  of  significant
     intercompany  accounts and  transactions.  Certain  items in the prior year
     financial  statements  have been  reclassified  to conform  to the  current
     presentation.

     These interim  financial  statements  have been prepared in conformity with
     accounting  principles that are generally  accepted in the United States of
     America,  sometimes  referred to as U.S.  GAAP.  To prepare  these  interim
     financial  statements,   management  is  required  to  make  estimates  and
     assumptions  that affect the reported amounts of assets and liabilities and
     disclosure  of  contingent  assets  and  liabilities  at  the  date  of the
     financial  statements,  as well as the  reported  amounts of  revenues  and
     expenses during the reporting periods. Actual amounts may differ from these
     estimates.

     The interim financial statements are unaudited;  however, in the opinion of
     management,  the interim  financial  statements  include  all  adjustments,
     consisting  only of  normal  recurring  adjustments,  necessary  for a fair
     statement  of the results for interim  periods.  These  interim  statements
     should be read in  conjunction  with the audited  financial  statements and
     related  notes  included  in the  Annual  Report on Form  10-K of  Trenwick
     America Corporation for the year ended December 31, 2000.

Note 4     Accounting Standards

     In July 2001, the Financial  Accounting  Standards Board issued  statements
     covering  business  combinations and goodwill and other intangible  assets,
     which are  required to be adopted at the  beginning  of 2002.  The business
     combination  statement  requires that the purchase  method of accounting be
     used for all  business  combinations  initiated  after June 30,  2001.  The
     goodwill and other  intangible  assets  statement  changes the expensing of
     goodwill  from  an  amortization  method  to an  impairment-only  approach.
     Amortization  of goodwill,  including  goodwill  recorded in past  business
     combinations, will cease upon adoption of this statement.

     Trenwick  America  Corporation  has not  determined  the  effect  that this
     statement will have on its  consolidated  financial  position or results of
     operations.

discretion of the respective rating agencies.

The  operating  loss of $7.0  million in the three  months  ended June 30,  2001
represented  a $10.6  million  decrease  from  operating  income of $3.6 million
recorded in the three months ended June

30,  2000.  This  decline was  principally  the result of reserve  strengthening
recorded in the second quarter of 2001,  offset in part by a decrease in general
and administrative expenses. The decrease of $11.2 million in net income in 2001
when  compared to 2000 was  primarily  the result of the  decrease in  operating
income.

The  underwriting  loss of $19.2  million in 2001  represented  a $10.7  million
greater loss  compared to the  underwriting  loss of $8.5  million in 2000.  The
increase  in  the   underwriting   loss  was   primarily  due  to  loss  reserve
strengthening  of $32.2  million  recorded  during 2001  arising  from  business
written in prior years.  The increase in the combined  ratio in 2001 compared to
2000 is also a result of the reserve strengthening noted above, partially offset
by a decrease in the underwriting expense ratio.

Treaty  reinsurance  decreased  $28.1  million  from the second  quarter of 2000
primarily  due  to the  non-renewal  of a  fronting  arrangement  acquired  in a
previous  business  combination.  Specialty  program  insurance  gross  premiums
written  increased  from $47.5  million for the second  quarter of 2000 to $74.9
million for the second  quarter of 2001 due to increased  volume on three of its
larger  existing  programs  combined  with the  addition of four new programs in
2001.

Gross premiums ceded for the three months ended June 30, 2001 were $57.1 million
compared to $91.9  million for the same  period in 2000.  The  decrease in gross
premiums  ceded of $34.7  million was due  primarily to the  non-renewal  of the
fronting arrangement previously described.

Net premiums  earned for the three months ended June 30, 2001 were $87.2 million
compared to $51.3  million for 2000.  The  increase  in net  premiums  earned is
commensurate with the increase in net premiums written.

Claims and claims expenses

Claims and claims  expenses  for the three months ended June 30, 2001 were $77.0
million,  an increase of $35.6 million compared to claims and claims expenses of
$41.4  million for 2000.  The increase in claims and claims  expenses in 2001 is
consistent   with  the  increase  in  premium  volume,   and  included   reserve
strengthening of $32.2 million and $10.5 million of additional claims and claims
expenses related to a stop loss reinsurance arrangement with an affiliate. These
amounts were reduced by a benefit of $25.7 million recorded under the terms of a
loss  sharing  agreement,  also with  affiliates,  compared  to a charge of $6.2
million  recorded for this agreement during the same period of 2000. The reserve
strengthening  of $32.2 million  included  $17.4  million  related to the treaty
reinsurance  segment's  directors and officer's  liability  business,  which was
underwritten  prior to 2001 and  $14.8  million  of loss  reserve  strengthening
related to one of the specialty program insurance segment's programs.

underwriting   expenses,   for  2001  decreased  by  $0.7  million  compared  to
underwriting  expenses  for  the  three  months  ended  June  30,  2000.  Policy
acquisition  costs as a  percentage  of earned  premium were 28.8% for the three
months ended June 30, 2001, a 2.6%  increase  over the same period in 2000.  The
increase in the acquisition ratio is primarily the result of a higher commission
ratio on treaties in runoff.  Underwriting  expenses  for the three months ended
June 30, 2001 as a  percentage  of earned  premium was 4.9%,  a decrease of 4.9%
from 9.8% for the same period in 2000. The decrease in the underwriting  expense
ratio resulted  primarily from a reallocation of expenses in 2001, when expenses
in the specialty  program  insurance  segment were reallocated from underwriting

expenses  to  loss  adjustment  expenses.   Total  underwriting  expenses  as  a

Net investment income for the three months ended June 30, 2001 was $18.3 million
compared  to $16.7  million  for the same  period in 2000.  The  increase in net
investment  income in 2001 was primarily due to the repositioning of investments
from equity  securities  and  tax-exempt  securities  into higher  yielding debt
securities.

Interest Expense and Dividends on Preferred Stock of Subsidiary

Interest  expense and  dividends on  preferred  stock of  subsidiaries  was $7.7
million for 2001, an decrease of $1.7 million from the same period in 2000.  The
increase  is  primarily  a result of a  reduction  in  interest  rates  over the
previous nine months.

Non-operating Income and Expenses

Net realized gains on investments, net of income taxes, were $0.2 million during
the three  months ended June 30,  2001,  compared to net realized  gains of $0.1
million  for the three  months  ended  June 30,  2000.  The gains were made as a
result of security sales executed  pursuant to an investment  policy designed to
protect the total returns on the portfolio.

Trenwick America  Corporation  recorded  foreign currency losses,  net of income
taxes,  of $0.4 million for the three  months  ended June 30, 2001,  compared to
foreign currency gains of $0.2 million for the three months ended June 30, 2000.

The  operating  loss of $1.4  million  in the six  months  ended  June 30,  2001
represented a $6.6 million  decrease  from the operating  income of $5.2 million
recorded in the six months ended June 30, 2000. This decline was principally the
result of loss  reserve  strengthening  recorded  during the first half of 2001,
combined with a decrease in general and administrative expenses. The decrease of
$4.1  million in net income in 2001 when  compared to 2000 was the result of the
decrease in net operating  income,  partially offset by the increase in realized
gains and the absence of an extraordinary loss in 2001.

The  underwriting  loss of $26.2  million in 2001  represented  a $12.6  million
greater loss compared to the  underwriting  loss of $13.6  million in 2000.  The
increases in the  underwriting  loss and the combined  ratio in 2001 compared to
2000 were both primarily due to loss reserve  strengthening  recorded during the
first half of 2001.

Premiums written

Gross premiums written for 2001 were $305.6 million compared to $255.1 million
for the six months ended June 30, 2000, an increase of $50.5 million or 19.8%.
Details of gross premiums written are provided below:

                                           ========      ========      ========

Treaty reinsurance  premiums decreased $1.0 million from the six months of 2000,
which can be attributed to the non-renewal of a fronting arrangement acquired in
a previous  business  combination,  offset by higher  than  anticipated  premium
volume  for the  2001  underwriting  year.  Specialty  program  insurance  gross
premiums  written  increased  from $92.0  million  for the six months of 2000 to
$143.5  million for the six months of 2001 due to  increased  volume on three of
its larger programs combined with the addition of four new programs in 2001.

Gross  premiums ceded for the six months ended June 30, 2001 were $109.9 million
compared to $139.3  million for the same period in 2000.  The  decrease in gross
premiums  ceded of $29.4  million  was due  primarily  to the  non-renewal  of a
fronting arrangement acquired in a previous business combination.

Net premiums  earned for the six months ended June 30, 2001 were $161.1  million
compared to $103.1  million for 2000.  The  increase in net  premiums  earned is
commensurate with the increase in net premiums written.

Claims and claims expenses

Claims and claims  expenses  for the six months  ended June 30, 2001 were $128.3
million,  an increase of $50.2 million compared to claims and claims expenses of
$78.1  million for 2000.  The increase in claims and claims  expenses in 2001 is
consistent with the increase in premium volume,  and is also attributable to the
$32.2 million of loss reserve  strengthening  recorded  during the first half of
2001 and $10.5 million of  additional  claims and claims  expenses  related to a
stop loss reinsurance  arrangement with an affiliate.  The reserve strengthening
of $32.2  million  included  $17.4  million  related to the  treaty  reinsurance
segment's  directors and officer's  liability  business,  which was underwritten
prior to 2001  and  $14.8 of the loss  reserve  strengthening  recorded  in 2001
related to one of the specialty program insurance segment's programs.

Total   underwriting   expenses,   comprising   policy   acquisition  costs  and
underwriting   expenses,  for  2001  increased  by  $20.4  million  compared  to
underwriting expenses for the six months ended June 30, 2000. Policy acquisition
costs as a percentage of earned premium were 31.5% for the six months ended June
30,  2001,  a 4.0%  increase  over the same period in 2000.  The increase in the
acquisition  ratio is  primarily  the  result  of a higher  commission  ratio on
treaties in runoff. Underwriting expenses for the six months ended June 30, 2001
as a  percentage  of earned  premium was 5.2%, a decrease of 4.9% from 10.1% for
the same period in 2000. The decrease in the underwriting expense ratio resulted
primarily  from a  reallocation  of  expenses  in  2001,  when  expenses  in the
specialty program insurance segment were reallocated from underwriting  expenses
to loss adjustment expenses.  Total underwriting expenses as a percentage of net
premiums  earned,  or the  underwriting  expense  ratio,  were 36.7% for the six
months ended June 30, 2001 compared to 37.5% for the same period in 2000.

Net  investment  income for the six months ended June 30, 2001 was $35.8 million
compared  to $36.6  million  for the same  period in 2000.  The  decrease in net
investment  income  in 2001  was  primarily  due to a  decrease  in the  average
invested assets as a result of cash used in operations.

Interest Expense and Dividends on Preferred Stock of Subsidiaries

Interest  expense and  dividends on preferred  stock of  subsidiaries  was $16.2
million for 2001, a decrease of $1.0  million from the same period in 2000.  The
decrease  is  primarily  a result of a  reduction  in  interest  rates  over the
previous nine months.

Non-operating Income and Expenses

Net realized gains on investments, net of income taxes, were $1.5 million during
the six months  ended June 30,  2001,  compared to net  realized  losses of $0.2
million for the six months ended June 30,  2000.  Both the gains and losses were
made as a result of security  sales  executed  pursuant to an investment  policy
designed to protect the total returns on the portfolio.

Trenwick America  Corporation  recorded  foreign currency losses,  net of income
taxes,  of $0.6  million  for the six months  ended June 30,  2001,  compared to
foreign currency losses of $0.5 million for the six months ended June 30, 2000.

Accounting Standards

In July  2001,  the  Financial  Accounting  Standards  Board  issued  statements
covering business  combinations and goodwill and other intangible assets,  which
are required to be adopted at the  beginning of 2002.  The business  combination
statement  requires  that the  purchase  method  of  accounting  be used for all
business  combinations  initiated  after June 30,  2001.  The goodwill and other
intangible  assets  statement  changes  the  accounting  for  goodwill  from  an
amortization  method to an impairment-only  approach.  Amortization of goodwill,
including  goodwill  recorded  in past  business  combinations,  will cease upon
adoption of this statement.  Trenwick America Corporation has not determined the
effect,  if any, that this  statement  will have on its  consolidated  financial
position or results of operations.
