                             OF CLAIMS AND INTERESTS

      Section 2.01.  General Rules of Classification  Under the Bankruptcy Code.
In accordance  with section  1123(a)(1) of the Bankruptcy  Code,  Administrative
Claims and Priority Tax Claims have not been  classified and, thus, are excluded
from the Classes as set forth below.  All other Claims and  Interests  have been
classified set forth below.

      A Claim or Interest is classified in a particular Class only to the extent
that the Claim or Interest  falls  within the  description  of that Class and is
classified  in other  Class(es)  to the extent  that any portion of the Claim or
Interest falls within the description of such other Class(es).

      A Claim is also placed in a particular  Class for the purpose of receiving
distributions  pursuant  to the Plan only to the  extent  that such  Claim is an
Allowed  Claim in that  Class and such  Claim has not been  paid,  released,  or
otherwise settled prior to the Effective Date.

      Section  2.02.  Undersecured  Claims.  To the extent that the amount of an
Allowed Claim is greater than the value of the Collateral securing such Claim as
of the  applicable  valuation  date  (assuming  the value of such  Collateral is
greater than $0),  subject to section 1111(b) of the Bankruptcy Code, such Claim
is classified in both Classes of Other Secured Claims for the secured portion of
such  Claim and the class of  General  Unsecured  Claims  for the excess of such
Claim over the value of the Collateral. Notwithstanding anything to the contrary
herein,  absent an order of the Bankruptcy Court or agreement fixing the Allowed
amount  of a  Secured  Claim or the  scheduling  of such  Claim  as  liquidated,
nondisputed and noncontingent on the Debtor's

herein with respect to any particular Claim.

Claim shall receive,  at the sole option of New TAC, (a) Cash in an amount equal

aggregate  amount  equal to such  Allowed  Priority  Tax  Claim,  together  with
interest  at the  Priority  Tax  Interest  Rate per  annum,  or such  other rate
determined  by the  Bankruptcy  Court,  on the unpaid  portion  of such  Allowed
Priority Tax Claim,  over a period not  exceeding six (6) years from the date of
assessment of such Allowed Priority Tax Claim.  Each Priority Tax Claim which is
not payable on or before the  Effective  Date will survive  confirmation  of the
Plan, remain unaffected thereby,  and be paid as and when due by New TAC, except
to the extent that a holder of such Claim agrees to a different treatment.

      Section 4.03. U.S.  Trustee Fees. The Debtor,  or New TAC, as the case may
be, shall pay all U.S.  Trustee Fees payable  under  Section 1930 of title 28 as

time as the Bankruptcy Court enters a final decree closing the Chapter l1 Case.

      Section 4.04. Review of Indenture Trustee Fees. Within ten (10) days after
the  Confirmation  Date,  each  Indenture  Trustee,  agent or servicer  shall be
required to provide the Plan Proponents  with copies of invoices  reflecting its
fees and expenses for review. In the event the parties cannot reach an agreement
on the  reasonableness  of any requested  amount,  any disputed  amount shall be
determined  upon  application  by  the  applicable  Indenture  Trustee,  to  the
Bankruptcy Court subject to a "reasonableness"  standard. All undisputed amounts
shall be paid,  pursuant to Sections 5.04, 5.05, and 5.09 hereof, as applicable.
The Indenture  Trustees shall retain all charging liens on  distributions  under
the Plan until  receipt of payment in Cash of the Indenture  Trustees'  fees and
expenses, including the fees and disbursements of counsel as determined pursuant
to this Section 4.04. Notwithstanding the foregoing, to the extent any Indenture
Trustee provides  services  related to distributions  pursuant to the Plan, each
Indenture  Trustee  shall be entitled to receive from New TAC,  without  further
court approval,  reasonable  compensation for such services and reimbursement of
reasonable expenses incurred in connection with such services, with such payment
made on terms as agreed to between such Indenture Trustee and New TAC; provided,

                         MEANS FOR IMPLEMENTING THE PLAN

      Section 6.01.  Managers of New TAC.  Commencing on the Effective Date, the
New TAC Limited Liability Company Agreement shall provide that the management of
New TAC shall be at the  direction  of the board of managers  of New TAC,  which
board shall consist of up to nine (9) persons, including (i) two (2) managers to
be designated by the Plan Proponents in consultation  with MBIA and the LoC Bank
Group, each of whom is not a Plan Proponent or an officer, director, employee or
Affiliate of a Plan Proponent or New TAC; (ii) five (5)  additional  managers to
be designated by the Plan  Proponents  at their sole  discretion;  (iii) one (1)
additional  manager  to be  designated  by the LoC Bank Group so long as the LoC
Bank Group holds any New TAC Debt Securities and (iv) one (1) additional manager
to be  designated by MBIA so long as it holds any New TAC Debt  Securities.  The
names of the managers shall be disclosed prior to the  Confirmation  Hearing and
set forth in the Plan  Supplement.  The managers of New TAC shall serve for five
(5) years and can only be  removed in  accordance  with the terms of the New TAC
Certificate of Formation and the New TAC Limited  Liability  Company  Agreement.
During such initial  five-year  period, in the event that any manager resigns or
is unable to perform the duties of a manager,  the  remaining  New TAC  managers
shall  appoint a new manager so long as the  appointment  of such new manager is
consented  to by the  party  or  constituency,  in  its  sole  discretion,  that
originally designated the resigning manager.

      Section  6.02.  New TAC  Certificate  of Formation  and Limited  Liability
Company Agreement.

      The adoption of the New TAC  Certificate  of Formation and New TAC Limited
Liability  Company Agreement will be deemed to have occurred and be effective as
of the  Effective  Date  without any further  action by the managers or interest
holders  of New  TAC.  The New  TAC  Certificate  of  Formation  and/or  Limited
Liability  Company  Agreement  will,  among other  things,  contain  appropriate
provisions  (i)  governing  the  authorization  and  issuance  of  the  New  TAC
Securities,  (ii) prohibiting the issuance of nonvoting  membership interests as
required by section  1123(a)(6) of the Bankruptcy Code, (iii) providing that New
TAC may not file a voluntary  bankruptcy petition absent the affirmative vote of
at  least  seven  (7) of the  members  of  the  board  of  directors,  and  (iv)
implementing such other matters as the managers of New TAC believe are necessary
and  appropriate to effectuate the terms and conditions of the Plan. On or prior
to the Effective  Date, the New TAC Certificate of Formation shall be filed with
the  Secretary of State of the State of  Delaware,  in  accordance  with section
18-201 of the Delaware Limited Liability Company Act. The New TAC Certificate of
Formation shall be  substantially  in the form

                                                                    Exhibit 99.1

contained  in the  Plan  Supplement.  New TAC  will  elect  to be  treated  as a
corporation for federal income tax purposes.

      Section 6.03.  Establishment and Funding of the Litigation Trust. Upon the
determination of the Plan  Proponents,  but in no event later than the Effective
Date, the Litigation Trust may be formed. The Litigation Trust, if formed, shall
be a statutory trust that shall be deemed a resident of the state in which it is
formed as of the Effective  Date. On the Effective  Date, the  Litigation  Trust
shall be funded in an amount equal to the Initial  Trust Funding  Amount.  As of
the Effective  Date,  the Litigation  Trust Assets,  which include the Causes of
Action,  will  automatically  vest in the Litigation Trust. The Litigation Trust
shall obtain the benefit of any tolling  provisions or  extensions  available to
the Estate or Debtor in Possession prior to the  Confirmation  Date or Effective
Date,  including  those  set  forth in  sections  108,  546,  549 and 550 of the
Bankruptcy Code.

      Section 6.04. The Litigation Trust Board. The Litigation Trust, if formed,
will be governed by the Litigation  Trust Board and the Litigation  Trust Assets
will be managed by the Litigation  Trustee(s),  subject to the provisions of the
Plan, the Confirmation Order and the Litigation Trust Agreement.  The Litigation
Trust Board  initially will be no less than a three (3) member board composed of
members who will be  identified in the Plan  Supplement.  The  Litigation  Trust
Agreement  shall  govern  compensation  of  Litigation  Trust Board  members and
changes in the  composition  of the  Litigation  Trust Board after the Effective
Date and other matters related to the role,  responsibilities  and governance of
the Litigation Trust Board.

      Section 6.05. The  Litigation  Trustee(s)  and  Preservation  of Causes of
Action.  (a) The Litigation  Trustee(s) will be the exclusive  trustee(s) of the
Litigation  Trust Assets for purposes of 31 U.S.C. ss. 3713(b) and 26 U.S.C. ss.
6012(b)(3),  as well as the  representative of the Estate appointed  pursuant to
section  1123(b)(3)(B) of the Bankruptcy  Code. The Litigation  Trustee(s) shall
have  fiduciary  duties to  beneficiaries  of the  Litigation  Trust in the same
manner that members of an official committee of creditors  appointed pursuant to
section  1102 of the  Bankruptcy  Code have  fiduciary  duties  to the  creditor
constituents represented by such a committee. The Litigation Trustee(s) shall be
identified  in  the  Plan  Supplement.   The  Litigation   Trustee(s)  shall  be
compensated from the Litigation Trust Assets, and the Litigation Trust Agreement
shall specify the terms and conditions of such compensation,  as well as provide
the manner in which the Litigation Trustee(s) may be removed.

            (b) In accordance  with section  1123(b)(3) of the Bankruptcy  Code,
the Litigation  Trustee(s) will retain and may (but are not required to) enforce
all Causes of Action except to the extent, and only to the extent, that any such
Causes of Action are explicitly  released pursuant to Section 7.07 of this Plan.
Pursuant  to the terms  hereof,  the  Litigation  Trustee(s),  in their sole and
absolute  discretion,   will  determine  whether  to  bring,  settle,   release,
compromise  or  enforce  the  Causes  of  Action  (or  decline  to do any of the
foregoing)  and will not be required to seek further  approval of the Bankruptcy
Court for such action.

      Section  6.06.   Responsibilities  of  the  Litigation   Trustee(s).   The
responsibilities  of  the  Litigation  Trustee(s)  shall  be  specified  in  the

the benefit of the beneficiaries of the Litigation  Trust;  (ii)  investigation,

in excess of the Initial Trust Funding Amount.

      Section 6.08.  Compensation of the Litigation  Trustee(s).  In addition to
reimbursement for the actual  reasonable and necessary  expenses  incurred,  the
Litigation Trustee(s), and any professionals,  employees, agents, or consultants

                                                    Trenwick America Corporation
                                                                    Exhibit 99.1

shall be entitled to reasonable  compensation  from the Litigation  Trust Assets
for  services  rendered  in  connection  with  performance  of the duties of the
Litigation   Trustee(s)  as  set  forth  above.  With  respect  to  any  agents,
consultants,  employees  engaged and  professionals  retained by the  Litigation

Litigation  Trust may be extended for a finite  period  based on the  particular
circumstances at issue; provided,  however, that such termination shall occur no
later  than the  tenth  anniversary  following  the  Effective  Date.  Each such
extension must be approved by the Bankruptcy  Court within six (6) months of the
beginning of the extended term with notice  thereof to all of the  beneficiaries
of the Litigation Trust.

      Section 6.10. New Senior  Subordinated  Notes and Senior  Litigation Trust
Certificates.  On the  Initial  Distribution  Date,  New TAC will  issue the New
Senior  Subordinated  Notes in accordance  with the Plan without  further act or
action  under  applicable  law,  regulation,  rule  or  order.  On  the  Initial
Distribution  Date,  the  Litigation  Trust will  issue to each  holder of a New
Senior  Subordinated Note Senior Litigation Trust  Certificates in the aggregate
Face Amount equal to the Face Amount of the New Senior Subordinated Notes issued
to such holder.  Following  the full  indefeasible  payment of the New Term Loan

respect of its New Senior  Subordinated  Notes and Trust  Payments in respect of
its Senior  Trust  Certificates  totaling the  aggregate  Face Amount of the New
Senior  Subordinated Notes distributed to it under the Plan. Trust Payments will
be paid by the Litigation  Trustee(s) in accordance  with the  Litigation  Trust
Agreement. Each Trust Payment with respect to a Senior Trust Certificate will be
deemed to also be a Debt  Payment  and will  reduce  the  outstanding  principal
amount of the New Senior Subordinated Note to which it corresponds by the amount
of such Trust Payment.  The New Senior  Subordinated Notes and the corresponding
Senior Trust Certificates  cannot be transferred,  sold or otherwise disposed of
separately.

      Section 6.11. New Junior  Subordinated  Notes and Junior  Litigation Trust
Certificates.  On the  Initial  Distribution  Date,  New TAC will  issue the New
Junior  Subordinated  Notes in

accordance  with the Plan without  further act or action under  applicable  law,
regulation,  rule or order.  On the Initial  Distribution  Date,  the Litigation
Trust will issue the Junior  Litigation  Trust  Certificates  in the Face Amount
equal to the Face  Amount of the New Junior  Subordinated  Notes  issued to such
holders.  Provided  that the holders of the New Senior  Subordinated  Notes have
received Debt Payments (including any Trust Payments deemed to be Debt Payments)
in the  aggregate  Face  Amount of the New Senior  Subordinated  Notes,  on each
Quarterly  Distribution Date each holder of a New Junior  Subordinated Note will
receive its Applicable  Share of the Debt Payments made by New TAC in respect of
the New Junior  Subordinated Notes on such Quarterly  Distribution Date, if any,
until the  earlier of the final  maturity  date of such New Junior  Subordinated
Notes or such time that such  holder  of the New  Junior  Subordinated  Note has
received Debt Payments in respect of its New Junior Subordinated Notes and Trust
Payments in respect of its Junior  Litigation  Trust  Certificates  totaling the
aggregate  Face Amount of the New Junior  Subordinated  Notes  distributed to it
under the Plan.  Trust  Payments  will be paid by the  Litigation  Trustee(s) in
accordance with the Litigation Trust Agreement. Each Trust Payment in respect of
Junior  Litigation Trust  Certificates  will be deemed to also be a Debt Payment
and will reduce the outstanding  principal amount of the New Junior Subordinated
Notes  attached  thereto  by the amount of such  Trust  Payment.  The New Junior
Subordinated  Notes and the corresponding  Junior Litigation Trust  Certificates
cannot be transferred, sold or otherwise disposed of separately.

      Section 6.12.  New TAC Interests and Residual Trust  Certificates.  On the
Initial  Distribution  Date,  New TAC will issue the New TAC  Interests  and the
Litigation  Trust will issue the Residual Trust  Certificates in accordance with
the Plan without further act or action under applicable law, regulation, rule or
order. At such time that all obligations  under the New TAC Debt Securities have
been paid in full,  holders  of the New TAC  Interests  and the  Residual  Trust
Certificates will be entitled to receive (i) distributions on account of the New
TAC  Interests,  to the extent  that there is  Available  Cash and is  otherwise
required  under this Plan,  and (ii) Trust  Payments in respect of the  Residual
Trust  Certificates.  The New TAC Interests and the Residual Trust  Certificates
cannot be transferred, sold or otherwise disposed of separately.

      Section 6.13. Applicability of Securities Laws and Reporting Requirements.
Under section 1145 of the  Bankruptcy  Code,  the issuance of New TAC Securities
and the Trust  Certificates  under the Plan shall be exempt from registration of
the  Securities  Act of 1933,  as amended,  and  equivalent  provisions in state
securities  law.  New TAC will take such  actions as required to comply with the
registration  and reporting  requirements  of the Securities and Exchange Act of
1934, as amended,  and if necessary  (upon  receiving the advice of counsel) the
Investment Company Act of 1940, as amended, including taking any and all actions
to comply with such reporting  requirements and file necessary  periodic reports
with the Securities and Exchange Commission.  The New TAC Securities will not be
listed on any securities exchange or any quotation system.

      Section 6.14.  Rights  Offering/Exit  Facility.  Each holder of an Allowed
Trust Preferreds  Claim that is an Accredited  Investor and is not an Insider of
the Debtor will be offered the opportunity to participate as a lender in the New
Revolver  Facility  and New Term Loan  Facility,  which  shall  serve as an exit
facility,  to be  made  available  upon  the  Effective  Date to New TAC and the
Litigation  Trust  pursuant to the New Loan  Agreement.  MBIA may elect to be an
assignee or participant in the New Revolver Facility.

Claim the  distribution  to which it would be  entitled  under  this Plan if its
Disputed Claim was an Allowed Claim.

            (b)  Estimation of Claims.  From and after the Effective  Date,  the
Plan Proponents or New TAC may, at any time,  request that the Bankruptcy  Court
estimate any Claim subject to estimation  under section 502(c) of the Bankruptcy
Code and for which New TAC may be liable under the Plan, including any Claim for
taxes,  to the  extent  permitted  by  section  502(c) of the  Bankruptcy  Code,
regardless of whether any party in interest  previously  objected to such Claim,
and the Bankruptcy Court will retain jurisdiction to estimate any Claim pursuant
to  section  502(c)  of the  Bankruptcy  Code  at  any  time  during  litigation
concerning  any  objection  to any Claim,  including  during the pendency of any
appeal  relating to any such objection.  In the event that the Bankruptcy  Court
estimates any  contingent  or  unliquidated  Claim,  that  estimated  amount may
constitute  either the Allowed  amount of such Claim or a maximum  limitation on
such Claim,  as  determined by the  Bankruptcy  Court.  If the estimated  amount
constitutes a maximum  limitation on such Claim,  the Plan Proponents or New TAC
may elect to  pursue  any  supplemental  proceedings  to object to any  ultimate
allowance on such Claim. All of the aforementioned Claims objection,  estimation
and resolution  procedures are cumulative and not  necessarily  exclusive of one
another.  Claims  may  be  estimated  and  subsequently  compromised,   settled,
withdrawn or resolved by any mechanism approved by the Bankruptcy Court.

            (c) Resolution of Disputed Claims.  No distribution or payment shall
be made on account of a Disputed  Claim  until such  Disputed  Claim  becomes an
Allowed  Claim.  No  Distribution  or payment  shall be made to any holder of an
Allowed  Claim who is also a potential  defendant in an  avoidance  action under
chapter 5 of the  Bankruptcy  Code unless and to the extent that such  avoidance
action has been waived, released,  enjoined,  discharged or otherwise limited by
the Plan or other order of the Bankruptcy  Court. For purposes of the Plan, such
distribution  or payment on account of such  Allowed  Claim shall be held in the
Disputed Claims Reserve Account as if it were a Disputed Claim, unless otherwise
ordered by the Bankruptcy  Court.  After the Effective  Date, New TAC shall have
the exclusive  right to make and file  objections  to and settle,  compromise or
otherwise  resolve Disputed Claims.  New TAC shall file and serve a copy of each
objection  upon the holder of the Claim to which an objection is made as soon as
practicable,  but in no event later than (i) one hundred-twenty (120) days after
the  Effective  Date, or (ii) such other time as may be fixed or extended by the
order of the Bankruptcy  Court.  After the Effective Date, New TAC may settle or
compromise any Disputed Claim without approval of the Bankruptcy Court.

            (d)  Distributions  when a Disputed  Claim Becomes an Allowed Claim,
Upon  Occurrence of a LoC Claim Date, or when a Disputed  Claim is  Subsequently
Disallowed.  On the first  Quarterly  Distribution  Date after a Disputed  Claim
becomes  an  Allowed  Claim,  New TAC  shall  make  Pro Rata  distributions,  in
accordance  with the  provisions of this Plan  (calculated  as of such Quarterly
Distribution  Date),  of Cash,  New TAC  Securities,  Trust  Certificates,  Debt
Payments  or Trust  Payments,  as the case may be, in respect  of such  Disputed
Claim that has


                                       36


                                                    Trenwick America Corporation
                                                                    Exhibit 99.1

become an Allowed Claim or for a LoC  Outstanding for which a LoC Claim Date has
occurred during the preceding  calendar quarter.  Any distributions  held in the
Disputed  Claims Reserve Account for the benefit of a holder of a Disputed Claim
which is subsequently  Disallowed,  in whole or part,  shall be included in Free
Cash  Flow  and  distributed,  on  the  next  Quarterly  Distribution  Date,  in
accordance   with  the   distribution  of  Free  Cash  Flow  on  such  Quarterly
Distribution Date.

            (e) Late  Claims.  Except as  otherwise  expressly  provided in this
Plan, any Claim not deemed Filed  pursuant to section  1111(a) of the Bankruptcy
Code or timely Filed pursuant to the Bankruptcy  Code,  Bankruptcy  Rules or any
applicable  order of the  Bankruptcy  Court,  shall not be treated as an Allowed
Claim.

      Section 6.16. Miscellaneous Distribution Provisions.

            (a) Method of Cash Distributions. Cash payments made pursuant to the
Plan shall be in U.S.  dollars by checks drawn on, or by wire  transfer  from, a
domestic bank selected by New TAC; provided, however, that cash payments made to
foreign  creditors,  if any,  holding Allowed Claims may be paid,  solely at the
option of New TAC in such funds and by such means as are reasonably necessary or
customary in a particular foreign jurisdiction.

            (b) Distributions on Non-Business  Days. Any payment or distribution
due on a day other than a Business Day shall be made,  without interest,  on the
next Business Day.

            (c) Accrual of Post-petition and Post-confirmation  Interest. Unless
otherwise  provided for in the Plan or by an order of the Bankruptcy  Court,  no
holder of a  Prepetition  Claim shall be  entitled  to the accrual of  interest,
during the pendency of the Chapter 11 Case or  post-confirmation,  on account of
such Claim.

            (d) No Distribution  Pending  Allowance.  Notwithstanding  any other
provision of this Plan, no Cash or other  property  shall be  distributed  under
this Plan on account of any Disputed Claim,  unless and until such Claim becomes
an Allowed Claim.  No  distribution or payment shall be made to any holder of an
Allowed  General  Unsecured  Claim  who is  also  a  potential  defendant  in an
avoidance  action under chapter 5 of the Bankruptcy Code.  Notwithstanding  this
section,  a  distribution  to such  potential  defendant  shall not constitute a
waiver of any rights of the Debtor, New TAC or the Litigation Trustee(s), as the
case may be. For purposes of the Plan,  such  distribution or payment on account
of such Allowed  General  Unsecured  Claim shall be held in the Disputed  Claims
Reserve Account as if it were a Disputed Claim.

            (e) No  Distribution  of  Fractional  New TAC  Securities  and Trust
Certificates.  Notwithstanding  any other  provisions  of the Plan,  only  whole
shares of New TAC Securities and Trust  Certificates  shall be issued.  When any
distribution  on account  of an  Allowed  Claim  would  otherwise  result in the
issuance of a number of New TAC Securities and Trust  Certificates that is not a
whole number,  any fractional New TAC  Securities  and Trust  Certificates  that
otherwise  would have been  distributed  shall be rounded to the  nearest  whole
number.  Notwithstanding  the foregoing,  if a Person holds more than one Claim,
the  fractional  New TAC  Securities  and Trust  Certificates  that such  Person
otherwise would be entitled to on account of each such Claim held


                                       37


                                                    Trenwick America Corporation
                                                                    Exhibit 99.1

by such  Person  shall  be  aggregated  and,  after  taking  into  account  such
aggregation,  such Person shall  receive on account  thereof (in addition to any
whole number of New TAC Securities, and Trust Certificates or other Distribution
such  Person is  entitled  to under  this Plan  prior to such  aggregation)  any
resulting  whole number of shares of New TAC Securities  and Trust  Certificates
with any remaining fractional New TAC Securities and Trust Certificates.

            (f)  No   Distribution   in  Excess  of  Allowed  Amount  of  Claim.
Notwithstanding  anything to the contrary herein,  no holder of an Allowed Claim
shall receive,  in respect of such Claim, any distribution (of a value set forth
herein or in the  Disclosure  Statement) in excess of the Allowed amount of such
Claim.

      Section 6.17. De Minimis  Distributions.  Notwithstanding  anything to the
contrary in the Plan, if the amount of Cash to be  distributed  to the holder of
an Allowed Claim in Classes 3, 4, 7, 9 or 10, as a Debt  Payment,  Trust Payment
or a distribution on account of a New TAC Security or Trust Certificate,  as the
case may be, is less than $50.00,  New TAC or the  Litigation  Trustee(s) as the
case may be, may hold the Cash distributions to be made to such holder until the
aggregate  amount of Cash to be distributed to such holder is in an amount equal
to or greater than $50.00 if New TAC or the Litigation Trustee(s) determine that
the cost to distribute  such Cash is unreasonable in light of the amount of Cash
to be distributed. Notwithstanding the preceding sentence, if the amount of Cash
distribution  to such holder never  aggregates to more than $50.00,  then on the
final  Distribution  Date, New TAC and the Litigation  Trustee(s) may distribute
such Cash to the holder entitled thereto.

      Section  6.18.  Setoffs.  Except as  otherwise  provided or limited in the
Plan,  the Debtor in  consultation  with the Plan  Proponents or New TAC, as the
case may be, is authorized,  pursuant to section 553 of the Bankruptcy  Code, to
set off against any Allowed Claim and the distributions to be made on account of
such Allowed Claim,  the claims,  rights and causes of action of any nature that
the Debtor may hold against the holder of such Allowed Claim; provided, however,
that neither the failure to effect such a setoff nor the  allowance of any Claim
hereunder  shall by itself  constitute  a waiver or release by the Debtor of any
such  claims,  rights and causes of action that the Debtor may  possess  against
such  holder.  The  amount  of  Trust  Certificates  and  Trust  Payments  to be
distributed  to the  holder of an  Allowed  Claim  shall be  reduced by the same
amount that the New TAC Debt Security is reduced pursuant to the right of setoff
hereunder.

      Section 6.19. Unclaimed Property.

            (a) Escrow of Unclaimed  Property.  Unclaimed Property (and all Debt
Payments, Trust Payments, distributions and other amounts paid thereon) shall be
delivered  promptly to New TAC. New TAC shall deposit such Unclaimed Property in
an account (for the benefit of the holders of Allowed  Claims  entitled  thereto
under the terms of this Plan).  For a period of one year following the Effective
Date, Unclaimed Property, including any interest, Debt Payments, Trust Payments,
distributions  on New TAC Interests,  and other amounts paid thereon,  shall be:
(i) held in such account solely for the benefit of the holders of Allowed Claims
that have failed to claim such property; and (ii) released from such account and
delivered to the holder of an Allowed Claim upon presentation of proper proof by
such holder of its entitlement  thereto. New TAC shall pay, or cause to be paid,
out of the funds held in such account, any tax


                                       38


                                                    Trenwick America Corporation
                                                                    Exhibit 99.1

imposed by any federal,  state or local taxing authority on the income generated
by the funds held in such account. New TAC shall also file, or cause to be filed
any tax or information  return  related to such accounts.  All Cash held in such
accounts  shall be invested in  accordance  with  section 345 of the  Bankruptcy
Code, as modified by the relevant orders of the Bankruptcy Court for investments
made by the Debtor during the Chapter 11 Case. The earnings on such  investments
shall be held in trust as an addition to the balance of the  subaccount  for the
benefit of the holders of Allowed Claims  entitled to such  Unclaimed  Property,
and shall not constitute property of New TAC.

            (b)  Distribution  of  Unclaimed  Property.  At the end of one  year
following  the  relevant  Distribution  Date,  the  holders  of  Allowed  Claims
theretofore  entitled to Unclaimed  Property shall cease to be entitled  thereto
(collectively,  such holders are referred to herein as the "Unclaimed Holders"),
and the Unclaimed  Property for each Unclaimed  Holder shall then be distributed
to New TAC and  thereafter  distributed  in accordance  with the Plan;  provided
however,  that any Trust Certificates  constituting  Unclaimed Property shall be
distributed  to  the  Litigation   Trustee(s)  and  thereafter   distributed  in
accordance  with the  Plan.  Unclaimed  Property  in the  form of Cash  shall be
distributed by New TAC on the next Quarterly  Distribution Date to those parties
entitled to the Free Cash Flow on such Quarterly  Distribution Date.  Securities
that are Unclaimed Property shall be cancelled.

      Section  6.20.  Exemption  from  Transfer  Taxes.  To the  fullest  extent
allowable by section 1146(c) of the Bankruptcy Code, the issuance,  transfer, or
exchange of a security,  or the making or delivery of an  instrument of transfer
under this Plan may not be taxed  under any law  imposing a stamp tax or similar
tax.

      Section 6.21.  Cancellation of Old Common Stock. As of the Effective Date,
by virtue of the Plan and in all  events  without  any action on the part of the
holders  thereof,  TAC or New TAC,  each  share of Old Common  Stock  issued and
outstanding  or  held  in  treasury  shall  be  cancelled  and  retired  and  no
consideration  will be paid or delivered with respect  thereto.  Notwithstanding
anything  herein to the  contrary,  holders  of Old  Common  Stock  shall not be
required to surrender such stock to the Debtor.

      Section 6.22. Cancellation of Senior Notes and Agreements,  Old Securities
and Other  Instruments.  As of the Effective Date, and in  consideration  of the
Trust  Certificates,  Trust Interests and New TAC Securities received under this
Plan,  except as otherwise  provided for in the Plan,  each Old Security and any
other note, bond,  Indenture (other than the Trust  Preferreds  Indentures),  or
other  instrument  or  document  evidencing  or  creating  any  indebtedness  or
obligation of the Debtor,  including  any guaranty  claims of the LoC Bank Group
against the Debtor,  will be deemed  cancelled and of no further force or effect
without any further  action on the part of the Bankruptcy  Court,  or any Person
including,  but not limited to, governmental agencies.  Notwithstanding the fact
that the Trust Preferreds Indentures are not cancelled hereunder,  for avoidance
of doubt, the  indebtedness  under the Trust  Preferreds  Indentures,  the Trust
Preferreds,  will be deemed cancelled because such indebtedness is treated under
the Plan.  The holders of such  cancelled Old  Securities and the LoC Bank Group
will have no claims against the Debtor for payment of such except for the rights
provided pursuant to the Plan.


                                       39


                                                    Trenwick America Corporation
                                                                    Exhibit 99.1

      On the Effective  Date,  the Old  Securities  will be surrendered to their
respective  Indenture  Trustee  in  accordance  with the  terms of the  relevant
Indenture. The Initial Distribution under this Plan in respect of Allowed Claims
under the Old Securities shall be made to the appropriate  Indenture Trustee for
the benefit of such holders. Following the Initial Distribution under this Plan,
the Indenture  Trustees  shall be  discharged  of all further  duties under each
Indenture  Trustee's  relevant  Indenture.  All distributions  subsequent to the
Initial  Distribution  shall be made (in each case in accordance  with the Plan)
pursuant to the  Litigation  Trust  Agreement  and (i) the New  Indentures  with
respect  to the New TAC  Debt  Securities  or (ii)  the New TAC  Certificate  of
Formation and Limited  Liability  Company  Agreement with respect to the New TAC
Interests.

      Any Old Security which is lost, stolen,  mutilated or destroyed,  shall be
deemed  surrendered  when the holder of a Claim  based  thereon  delivers to the
applicable  Indenture  Trustee,   agent,   servicer  or  New  TAC  (a)  evidence
satisfactory to the Indenture Trustee,  agent,  servicer or New TAC of the loss,
theft, mutilation or destruction of such instrument or certificate, and (b) such
security  or  indemnity  as may be  required by the  Indenture  Trustee,  agent,
servicer or New TAC to hold each of them harmless with respect thereto.

      With the exception of the Trust  Preferreds  Indentures which shall remain
in full effect, each Indenture or other agreement that governs the rights of the
holder of a Claim and that is administered by an Indenture Trustee,  an agent or
a servicer,  shall  continue in effect  solely for the purposes of allowing such
Indenture  Trustee,  agent or servicer to make the  distributions  to be made on
account  of such  Claims  under  this  Plan.  Notwithstanding  the  terms of the
foregoing  sentence and any other term of this Plan  providing for the continued
efficacy of the Trust Preferreds Indentures,  HSBC shall be permanently released
and discharged from all duties, obligations and responsibilities under the Trust
Preferreds Indentures immediately following the Initial Distribution.

      The Indenture  Trustees shall retain all charging  liens on  distributions
under the Plan until receipt of payment in Cash of the Indenture  Trustee's fees
and  expenses,  including  the fees and  disbursements  of counsel as determined
pursuant to Section 4.04 of the Plan.

      Section  6.23.  Instructions  to New  TAC.  Prior to any  distribution  on
account of any Old Securities,  an Indenture Trustee shall (a) inform New TAC as
to the amount of properly  surrendered Old Securities,  and (b) instruct New TAC
in a form and manner that New TAC reasonably determines to be acceptable, of the
names of the  holders  of Old  Securities  who are to receive  Distributions  in
exchange for properly surrendered Old Securities;  alternatively,  to the extent
such Old Securities are held in electronic  format, a report from the applicable
clearinghouse.

      Section 6.24. Disputed Payments.  If any dispute arises as to the identity
of a holder of an Allowed Claim who is to receive any distribution, New TAC may,
in lieu of making such distribution to such Person,  make such distribution into
an  account  to be held in trust for the  benefit  of such  holder and shall not
constitute  property of the Debtor, its Estate, New TAC or the Litigation Trust.
Such distribution shall be held in escrow until the disposition thereof shall be
determined  by  order of the  Bankruptcy  Court  or  other  court  of  competent
jurisdiction  or by  written  agreement  among the  interested  parties  to such
dispute.

                                                    Trenwick America Corporation
                                                                    Exhibit 99.1

      Section  6.25.  Withholding  Taxes.  In  connection  with the Plan, to the
extent  applicable,  New TAC shall  comply with all  withholding  and  reporting
requirements imposed on it by federal,  state and local taxing authorities,  and
all   distributions   shall  be  subject  to  such   withholding  and  reporting
requirements.

      Section  6.26.  Obligations  Incurred  After the Effective  Date.  Payment
obligations  incurred after the Effective Date,  including,  without limitation,
the fees and expenses of  Professionals,  shall not be subject to application or
Proof of Claim and may be paid by New TAC in the ordinary course of business and
without further Bankruptcy Court approval.

      Section 6.27. Distribution Record Date for Distributions to Holders of Old
Securities.  On the  Distribution  Record  Date,  the  transfer  ledgers  of the
Indenture Trustees shall be closed, and there shall be no further changes in the
record  holders of the Old  Securities.  The Debtor,  New TAC and the  Indenture
Trustees,  agents and servicers for such Old Securities shall have no obligation
to  recognize  any  transfer  of  such  Old  Securities   occurring  after  such
Distribution Record Date. The Debtor, New TAC and the Indenture Trustees, agents
and servicers for such Old Securities shall be entitled instead to recognize and
deal for all purposes  hereunder  with only those record  holders  stated on the
transfer ledgers as of the close of business on such Distribution Record Date.

      Section  6.28.  Restructuring  Transactions  Generally.  On or before  the
Effective  Date,  the  Debtor  may,  but is not  obligated  to,  enter into such
Restructuring  Transactions  and may, but is not obligated to, take such actions
as may be necessary or  appropriate to effect a corporate  restructuring  of its
business  or  simplify  its  overall  corporate  structure.   The  Restructuring
Transactions  that  are  potentially  contemplated  to occur  on or  before  the
Effective  Date will be described more fully in the Plan  Supplement;  provided,
however,  that the Plan  Proponents  reserve  the right to direct  the Debtor to
undertake  transactions  in lieu  of,  or in  addition  to,  such  Restructuring
Transactions as may be necessary or appropriate  under the  circumstances.  Such
transactions   may  include  one  or  more   mergers,   sales,   consolidations,
restructurings, acquisitions, dispositions, liquidations or dissolutions, as may
be determined by the Plan  Proponents in  consultation  with the Committee to be
necessary or appropriate. The actions to effect these Restructuring Transactions
may include:  (a) the execution and delivery of appropriate  agreements or other
documents of merger, sale consolidation, restructuring, disposition, liquidation
or dissolution  containing  terms that are consistent with the terms of the Plan
and that satisfy the applicable  requirements  of applicable  state law and such
other terms to which the  applicable  entities may agree;  (b) the execution and
delivery of  appropriate  instruments  of transfer,  assignment,  assumption  or
delegation of any asset, property, right, liability, duty or obligation on terms
consistent  with the terms of the Plan and having  such other terms to which the
applicable  entities may agree;  (c) the filing of appropriate  certificates  or
articles of merger,  consolidation,  incorporation  or  dissolution  pursuant to
applicable  state law; and (d) all other  actions that the  applicable  entities
determine to be necessary or appropriate, including making filings or recordings
that  may  be  required  by  applicable   state  law  in  connection  with  such
Restructuring  Transactions.  Notwithstanding  anything to the contrary  herein,
Restructuring  Transactions  shall be  limited to such  transactions  reasonably
necessary and  appropriate  to effect the provisions of the Plan and to maximize
the benefit to be realized  from TAC's  consolidated  tax group's net  operating
losses.

                                                    Trenwick America Corporation
                                                                    Exhibit 99.1

      Section  6.29.  Obligations  of Any  Successor  Entity in a  Restructuring
Transaction.  The  Restructuring  Transactions  may include one or more mergers,
sales,   consolidations,    restructurings,    dispositions,   liquidations   or
dissolutions,  as may be determined by the Plan Proponents in consultation  with
the Creditors' Committee (and subject to Section 6.28 hereof) to be necessary or
appropriate to result in substantially all of the respective assets, properties,
rights, liabilities, duties and obligations of the Debtor vesting in one or more
surviving,  resulting or acquiring limited liability  companies or corporations.
In each case in which the surviving,  resulting or acquiring  limited  liability
company in any such  transaction is a successor to the Debtor,  such  surviving,
resulting or acquiring limited liability company will perform the obligations of
the Debtor  and/or New TAC pursuant to the Plan to pay or otherwise  satisfy the
Allowed Claims against such Debtor.

      Section 6.30. New Operational Subsidiary. On or before the Effective Date,
TARCO shall create a new subsidiary,  TASCO, that will employ all of the current
employees  of TAC who are  currently  providing  services  to InsCorp and TARCO,
among  others,  and maintain  responsibility  for the  operations of InsCorp and
TARCO and others to the extent  agreed upon by New TAC. TAC will also enter into
an administrative  services agreement with TASCO, whereby TASCO will provide TAC
with services related to the administration of TAC's Chapter 11 estate.

      Section 6.31. Regulatory Filings. The Debtor and New TAC shall continue to
be responsible for preparing,  and shall cause their respective subsidiaries and
affiliates,  if  necessary  and  as  appropriate,  to  prepare  the  appropriate
regulatory  filings  in the  ordinary  course  with their  respective  governing
regulatory bodies with respect to insurance matters.

      Section  6.32.  Form A  Filings.  Prior to any change of  control,  Form A
Filings shall be filed with and approved by the appropriate governing regulatory
bodies.

      Section 6.33. Post-Confirmation Action.

            (a)   Post-Confirmation,   Pre-Effective  Date.  Subsequent  to  the
Confirmation Date, but prior to the Effective Date, the Debtor shall continue to
operate its business in the ordinary  course in accordance  with the  Bankruptcy
Code and any applicable  Bankruptcy Court orders  affecting the same,  including
any order, which may be the Confirmation Order,  entered by the Bankruptcy Court
at the request of the Plan Proponents  establishing operating guidelines for the
Debtor,  which  guidelines  shall be  included  in the Plan  Supplement  and are
subject to regulatory approval.

            (b)  Post-Effective  Date. In accordance with section 1142(b) of the
Bankruptcy Code and section 303 of the Delaware General Corporation Laws, on the
Effective  Date,  all matters  provided for under the Plan that would  otherwise
require approval of the  stockholders,  directors,  or members of one or more of
the Debtor,  New TAC, the Plan  Proponents,  or any other Person under the Plan,
including,  without limitation, the authorization to issue or cause to be issued
the New TAC Securities,  the  effectiveness  of New TAC Certificate of Formation
and the New TAC  Limited  Liability  Company  Agreement,  corporate  mergers  or
dissolutions  effectuated pursuant to the Plan, and the election or appointment,
as the case may be, of  directors  and officers of New TAC pursuant to the Plan,
shall be deemed  to have  occurred


                                       42


                                                    Trenwick America Corporation
                                                                    Exhibit 99.1

and  shall be in  effect  from and  after the  Effective  Date  pursuant  to the
applicable general corporation or similar laws of the State of Delaware, without
further order of the  Bankruptcy  Court and without any  requirement  of further
action by the  stockholders,  directors  or  members  of TAC or New TAC.  On the
Effective  Date or as soon  thereafter  as is  practicable,  New TAC  shall,  if
required,  file its New TAC Certificate of Formation with the Secretary of State
of the State of Delaware, in accordance with the applicable law of such state.

      Section 6.34.  Election of Treatment in Class 8. Each holder of a Claim in
Class 7 may elect, in the Ballot by which it votes to accept or reject the Plan,
to reduce the  amount of its Claim to  $500.00  or less and  thereby be deemed a
holder of a Claim in Class 8 for purposes of voting and payment  under the Plan.

changes to the Plan,  which  changes may be  necessary.  If the Plan  Proponents

constitute a waiver or release of the Claims by Plan Proponents or by or against
the Debtor,  or to prejudice in any manner the rights of the Plan  Proponents or
any  other  persons  in any  further  proceedings  involving  the  Debtor.  Each
provision of this Plan shall be considered separable, and, if for any reason any
provision or provisions  herein are determined to be invalid and contrary to any
existing or future law, the balance of this Plan shall be given  effect  without
relation to the invalid provision.

      Section 10.02. Cram-down. The Plan Proponents reserve the right to request
the Bankruptcy  Court to confirm the Plan in accordance  with section 1129(b) of
the  Bankruptcy  Code if one or more  impaired  Classes votes to reject the Plan
(provided  the other  requirements  of section 1129 of the  Bankruptcy  Code are
satisfied).

                                                    Trenwick America Corporation
                                                                    Exhibit 99.1

compensation or  reimbursement  of expenses  pursuant to sections 327, 328, 330,
331,  503(b) and 1103 of the Bankruptcy  Code for services  rendered  before the

Proponents  with a statement,  by no later than the  Confirmation  Date,  of the
amount of estimated  unpaid fees and expenses  that each such  Professional  has
incurred  or expects to incur  through  the  Effective  Date.  The Debtor at the

reserve in an amount  sufficient to satisfy the unpaid fees and expenses of such

pursuant to the terms and conditions of the particular  transaction  giving rise
to such Administrative  Claim, without any further action by the holders of such
Claims or the Bankruptcy Court.

      Section 11.05.  Payment of Statutory  Fees.  All fees payable  pursuant to
section  1930 of  title 28 of the  United  States  Code,  as  determined  by the
Bankruptcy Court on the Confirmation  Date, shall be paid on the Effective Date.
Any  statutory  fees  accruing  after  the  Confirmation  Date  shall be paid in

action as may be  necessary  to  effectuate  and further  evidence the terms and
conditions of the Plan.

      Section  11.07.   Successors  and  Assigns.  The  rights,   benefits,  and
obligations  of any  Person  named or  referred  to in the Plan shall be binding
upon,  and shall  inure to the benefit  of, the heir,  executor,  administrator,
successor or assign of such Person, but as for any releases provided  hereunder,
only in their capacity as such.

      Section 11.08.  Early  Assignment of Causes of Action.  To the extent that
the Plan  Proponents  file a notice with the Court  notifying the Court that any
delay in the Effective Date of the Plan is potentially jeopardizing the value of
any of the Causes of Action,  as a result for  example of  potential  statute of
limitations  issues,  the Court may thereafter upon application by the Debtor or
the  Plan  Proponents,  on ten (10)  days  notice,  or such  shorter  notice  as
necessary  and after a hearing on the matter to  preserve  the Causes of Action,
enter any orders  necessary to

assign and transfer the Causes of Action and/or  otherwise  provide  standing to
the Plan Proponents, as appropriate,  prior to the Effective Date, with the Plan
Proponents  having all rights  and powers  with  respect to the Causes of Action
that would  otherwise be given to the Litigation  Trustee(s)  upon the Effective
Date.  Upon such  orders,  the Plan  Proponents  shall  obtain  the  benefit  of
bankruptcy  tolling  provisions  or  extensions,  including  those  set forth in
sections 108, 546, 549 and 550 of the  Bankruptcy  Code. If the Causes of Action
are assigned  and/or  standing is otherwise  provided to the Plan  Proponents in
accordance with this provision, such Causes of Action will automatically vest in
the  Litigation  Trustee(s)  upon the  Effective  Date in accord  with the above
provisions.

date that the Bankruptcy Court enters a Final Order closing the Chapter 11 Case.

      Section  11.10.  Confirmation  Order and Plan  Control.  To the extent the

Statement,  any other agreement entered into between or among the Debtor and any
third  party,  this  Plan  controls  the  Disclosure   Statement  and  any  such
agreements,  and the Confirmation  Order (and any other orders of the Bankruptcy
Court) controls this Plan.

      Section 11.11.  Headings.  Headings are used in this Plan for  convenience
and reference  only,  and shall not constitute a part of this Plan for any other
purpose.
