                       Report of Independent Accountants


To the Benefit Plans Committee and Participants of the
Crown Cork & Seal Company, Inc. 401(k) Retirement Savings Plan

In our opinion, the accompanying statements of net assets available for benefits
and the  related  statements  of changes in net assets  available  for  benefits
present fairly, in all material respects,  the net assets available for benefits
of the Crown Cork & Seal  Company,  Inc.  401(k)  Retirement  Savings  Plan (the
"Plan") at December 31, 2000 and 1999,  and the changes in net assets  available
for benefits for the years then ended, in conformity with accounting  principles
generally accepted in the United States of America.  These financial  statements
are the  responsibility  of the  Plan's  management;  our  responsibility  is to
express  an  opinion  on these  financial  statements  based on our  audits.  We
conducted our audits of these  statements in accordance with auditing  standards
generally  accepted in the United States of America,  which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial  statements  taken as a whole.  The  supplemental  schedules of assets
(held at end of year)  and of  reportable  transactions  are  presented  for the
purpose  of  additional  analysis  and are  not a  required  part  of the  basic
financial   statements  but  are  supplementary   information  required  by  the
Department of Labor's Rules and Regulations  for Reporting and Disclosure  under
the  Employee  Retirement  Income  Security  Act  of  1974.  These  supplemental
schedules are the  responsibility  of the Plan's  management.  The  supplemental
schedules have been subjected to the auditing  procedures  applied in the audits
of the basic financial  statements and, in our opinion, are fairly stated in all
material  respects  in  relation to the basic  financial  statements  taken as a
whole.

CROWN CORK & SEAL COMPANY, INC. 401(k)
RETIREMENT SAVINGS PLAN
Notes to Financial Statements
- --------------------------------------------------------------------------------

NOTE 1 - DESCRIPTION OF PLAN

The  following  description  of the  Crown  Cork & Seal  Company,  Inc.  401 (k)
Retirement  Savings  Plan  (the  "Plan")  provides  only  general   information.
Participants  should refer to the Plan document for a more complete  description
of the Plan's provisions.

General
The plan is a defined contribution plan. The purpose of the Plan is to provide a
convenient method by which eligible employees of Crown Cork & Seal Company, Inc.
(the "Company") may save regularly  through salary deferrals and through Company
matching contributions.  Generally, employees are eligible to participate in the
Plan after  completing  one year of service  and  attaining  age 21. The Plan is
subject to the provisions of the Employee Retirement Income Security Act of 1974
("ERISA").

The Plan is  administered by the Crown Cork & Seal Company,  Inc.  Benefit Plans
Committee  (the  "Committee").  The Committee has appointed  Vanguard  Fiduciary
Trust   Company   ("VFTC")   to   assume   both   trustee   and    recordkeeping
responsibilities.

During 1999,  the Company sold a segment of the  Composite  Can  division.  As a
result  of this  transaction,  participant  accounts  of  former  Composite  Can
employees were transferred out of the Plan in 2000 in the amount of $1,069,385.

The Crown Cork & Seal Company,  Inc. 401(k) Retirement Savings Plan for Salaried
Employees  of CONSTAR  International,  Inc.  ("CONSTAR  Salaried  401(k)"),  the
participant  accounts of the salaried  employees of Zeller Plastik,  Inc. 401(k)
Savings  Plan  ("Zeller")  and  the  Crown  Cork &  Seal  Company,  Inc.  401(k)
Retirement  Savings Plan for Employees of Golden  Aluminum  ("Golden  Aluminum")
were merged with and into the Plan effective March 31, 1999, August 31, 1999 and
December 31, 1999,  respectively.  The assets transferred  totaled  $20,982,739,
$966,188 and  $1,110,242  for CONSTAR  Salaried  401(k),  Golden  Aluminun,  and
Zeller, respectively. In addition, $231,045 of assets from the Crown Cork & Seal
Company, Inc. 401(k) Retirement Savings Plan for Employees of Risdon Corporation
("Risdon 401(k)") were transferred in February 1999. The other assets related to
the Risdon 401(k) were  transferred  upon  completion of the plan merger,  which
occurred in 1998.

During these conversions, freeze periods were enforced to restrict transactions.
Once the  freeze  periods  were  lifted  participants  could  change  investment
elections.

Contributions
Generally,  the Plan has two  components:  a participant  salary deferral 401(k)
component and a Company  matching  contribution  component.  The salary deferral
401(k) component of the plan allows before-tax  employee  contributions of 2% to
12%  of  annual  compensation.  Contribution  amounts  are  subject  to  certain
limitations,  $10,500 in 2000 and $10,000 in 1999,  as  prescribed  by law.  The
Company  makes  matching  contributions  equal to 50 percent  of the  employee's
contribution,  from  3% up to 6% of  compensation,  depending  on  the  employer
company.  Participants direct the investment of their contributions into various
investment  options offered by the Plan.  Company  contributions are invested in
Company common stock.



                                        4





Participant Accounts
Each participant's  account is credited with participant's  contribution and the
participant's allocation of the Company's contribution, as described above. Plan
earnings  are  allocated to the  participant's  account  based on  participant's
account balances.  The benefit to which a participant is entitled is the benefit
that can be provided from the participant's vested account.

Vesting
Participants are immediately vested in their  contributions plus actual earnings
thereon.  Vesting in the Company's  contribution plus actual earnings thereon is
based on years of continuous  service.  Generally,  a participant is 100 percent
vested after four years of credited service.

Participant Loans
Participants  may borrow from their  account a minimum of $1,000 up to a maximum
equal to the  lesser  of  $50,000  or 50  percent  of the  participant's  vested
balance.  Loan  transactions  are treated as a transfer to (from) the investment
fund from (to) Participant loans. Loan terms range from 1 to 5 years or up to 10
years for the  purchase  of a primary  residence.  The loans are  secured by the
balance in the  participant's  account and bear interest at a rate  commensurate
with a prevailing  commercial  rate for a secured  personal loan.  Principal and
interest is paid ratably through monthly payroll  deductions.  A participant may
not have more than two outstanding loans at any one time.

Payment of Benefits
On termination of service due to death, disability or retirement,  a participant
may  elect  to  receive  either  a lump sum  amount  equal  to the  value of the
participant's  vested  interest in his or her account,  or  substantially  equal
periodic  installments  over a  period  equal  to  the  life  expectancy  of the
recipient or  beneficiary.  For  termination of service due to other reasons,  a
participant  may receive the value of the vested  interest in his or her account
as a lump-sum distribution. All distributions are paid in either cash or company
stock at the participant's election.

Forfeited Accounts
Total  unallocated  forfeitures,  which will be used to reduce  future  employer
contributions,   were  $23,580  and  $1,485  at  December  31,  2000  and  1999,
respectively.   These   amounts   will  be  used  to  reduce   future   employer
contributions.  In 2000 and 1999, $668 and $74,181, respectively, of unallocated
forfeitures were used to offset employer contributions.

Plan Termination
Although  it has not  expressed  any intent to do so, the  Company has the right
under the Plan to discontinue its contributions at any time and to terminate the
Plan  subject  to the  provisions  of ERISA.  In the event of Plan  termination,
participants will become 100 percent vested in their accounts.

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES

The following  accounting  policies,  which conform with  accounting  principles
generally accepted in the United States of America,  have been used consistently
in the preparation of the Plan's financial statements:

Basis of Accounting
The financial  statements of the Plan are prepared  under the accrual  method of
accounting.

Use of Estimates
The  preparation  of  financial   statements,   in  conformity  with  accounting
principles  generally  accepted  in  the  United  States  of  America,  requires
management 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 reported amounts of additions
and  deductions  during the reporting  period.  Actual results could differ from
those estimates.

Investment Valuation and Income Recognition
The  Plan's  investments  are stated at fair  value  except  for its  investment
contracts,  which are valued at contract  value (Note 5).  Shares of  registered
investment  companies are valued at quoted market prices which represent the net
asset value of shares held by the Plan at  year-end.  The Company  stock fund is
valued at its year-end  unit closing price  (comprised of year-end  market price
plus  uninvested  cash  position).  Units of the Company's fixed income fund are
valued at net asset  value at  year-end.  Participant  loans are valued at cost,
which approximates fair value.

Purchases and sales of investments are recorded on a trade-date basis.  Interest
income is accrued when earned.  Dividend  income is recorded on the  ex-dividend
date. Capital gain distributions are included in dividend income.

New Accounting Pronouncements
In June 1998,  the  Financial  Accounting  Standards  Board issued SFAS No. 133,
"Accounting for Derivative  Instruments and Hedging Activities" ("SFAS No. 133")
which  requires  that an entity  recognize  all  derivatives  and measure  those
instruments at fair value.

SFAS No. 133 was effective for the Plan January 1, 2001.  Management has not yet
been  able to  determine  the  impact  of SFAS  No.  133 on the  Plan  financial
statements as a result of the  inconsistency  in accounting  literature  between
SFAS No. 133, requiring  derivatives to be measured at fair value, and the AICPA
Audit and Accounting  Guide on "Audits of Employee  Benefit Plans" and Statement
of Position 94-4,  "Reporting of Investment Contracts Held by Health and Welfare
Benefit  Plans  and  Defined-Contribution   Pension  Plans",  requiring  benefit
responsive investment contracts (including synthetic investment contracts) to be
measured at contract value.  Until this  discrepancy is resolved,  management is
unable to determine the impact that SFAS No. 133 will have on the Plan financial
statements.  The  carrying  value of the  Plan's  synthetic  benefit  responsive
investment contracts was $3,186,594 at December 31, 2000.

The  actual  impact on the  Plan's net assets  available  for plan  benefits  of
adopting SFAS No. 133 will be made based on the derivative positions and hedging
relationships at the date of adoption.

NOTE 5 - CROWN CORK & SEAL FIXED INCOME FUND

The Crown Cork & Seal Fixed  Income Fund (the  "Fund")  consists  of  guaranteed
investment  contracts of  $15,349,211  and synthetic  investment  contracts with
various banks and insurance companies ("Issuers").  Additionally, the Fund holds
units of the  Vanguard  Retirement  Savings  Trust,  a  common/commingled  trust
sponsored by VFTC with a value of $34,111,299.  The Vanguard  Retirement Savings
Trust (the  "Trust") is a  tax-exempt  collective  trust  invested  primarily in
investment  contracts  issued by insurance  companies and commercial  banks, and
similar types of  fixed-principal  investments.  The Trust intends to maintain a
constant net asset value of $1.00 per unit.  The Fund is credited  with earnings
on  the   underlying   investments   and  charged  for  Plan   withdrawals   and
administrative  expenses  charged  by  the  Issuers.  The  investment  contracts
included in the Fund are  carried at contract  value,  which  approximates  fair
value,  because  the  contracts  are fully  benefit  responsive.  The  synthetic
investment  contracts  constitute   investments  in  common  collective  trusts,
$3,186,370,  and wrapper  contracts,  $224. The value provided  (reduced) by the
wrapper contracts  represents the difference  between the value of the synthetic
investment contracts and the underlying investments.  The Fund also included net
other  liabilities  (including  units  receivable  and payable) in the amount of
$34,564.  The crediting  interest rates of the investment  contracts ranged from
2.16% to 6.69% at December 31, 2000. As the contracts  mature,  the proceeds are
invested in the Vanguard Retirement Savings Trust.

NOTE 6 - RELATED PARTY TRANSACTIONS

The  Plan   invests   in  shares  of   registered   investment   companies   and
common/collective trusts managed by affiliates of VFTC. VFTC acts as trustee for
investments of the Plan. The Plan also invests in shares of the Company's  stock
through the Crown Cork & Seal Company,  Inc.  Stock Fund.  Transactions  in such
investments  qualify as  party-in-interest  transactions and are exempt from the
prohibited transaction rules.

NOTE 7 - PLAN EXPENSES

All  recordkeeping  expenses  for  the  administration  of the  Plan,  with  the
exception of certain miscellaneous fees, are paid by the Company.

NOTE 8 - TAX STATUS

The Internal Revenue Service has determined and informed the company by a letter
dated  February  22,  1996  that the Plan and  related  trust  are  designed  in
accordance with applicable  sections of the Internal  Revenue Code ("IRC").  The
Plan has been amended since receiving the  determination  letter.  However,  the
Plan  administrator  believes  that the Plan is designed and is currently  being
operated in compliance with the applicable provisions of the IRC.
