              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  statement of net assets available for benefits
and the  related  statement  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, 1998 and 1997,  and the changes in net assets  available
for benefits for the years then ended,  in conformity  with  generally  accepted
accounting principles.  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  generally  accepted  auditing  standards  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 the opinion expressed above.

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
for  investment  purposes 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.

As explained in Note 1, the Crown Cork & Seal Company,  Inc.  401(k)  Retirement
Savings Plan for Employees of Van Dorn Company and the  participant  accounts of
the  salaried  employees of Crown Cork & Seal  Company  Inc.  401(k)  Retirement
Savings  Plan  for  Employees  of  Risdon  were  merged  with  and into the Plan
effective September 30, 1998 and December 31, 1998, respectively.

401(k) Retirement Savings Plan

 1.  Description of Plan

     The following  description  of the Crown Cork & Seal Company,  Inc.  401(k)
     Retirement  Savings  Plan  ("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  appointed  Vanguard
     Fiduciary Trust Company  ("VFTC") to assume both trustee and  recordkeeping
     responsibilities.

     The Crown Cork & Seal  Company,  Inc.  401(k)  Retirement  Savings Plan for
     Employees  of Van Dorn  Company  ("Van Dorn  401(k)")  and the  participant
     accounts  of the  salaried  employees  of Crown Cork & Seal  Company,  Inc.
     401(k) Retirement Savings Plan for Employees of Risdon Corporation ("Risdon
     401(k)")  were merged with and into the Plan  effective  September 30, 1998
     and  December  31,  1998,  respectively.  The  assets  transferred  totaled
     $13,208,228  and  $21,636,300  for the Van Dorn  401(k) and Risdon  401(k),
     respectively.  The Risdon 401(k) assets were  transferred  from Fleet Bank,
     the former Risdon 401(k)  trustee,  to VFTC,  and mapped to the  respective
     VFTC funds,  in February 1999, and are recorded as a Plan asset at December
     31, 1998.  During the  conversion  process a freeze  period was enforced to
     restrict  transactions.  Once the freeze  period was lifted on November 17,
     1998 and  March  26,  1999  for the Van  Dorn  401(k)  and  Risdon  401(k),
     respectively, participants could change investment elections.

     Contributions
     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.  The Plan also  allows
     after-tax  employee  contributions  of 1% to  8%  of  annual  compensation.
     Contribution  rates are subject to certain  limitations,  as  prescribed by
     law. The Company makes  matching  contributions  equal to 50 percent of the
     employee's  contribution,  up to a maximum  of 3 percent  of  compensation.
     Company contributions are made in the form of Company common stock.

     Participant Accounts
     Each participant's account is credited with the participant's  contribution
     and  the  participant's  allocations  of the  Company's  contributions,  as
     described above. Plan earnings are allocated to the participant's  accounts
     based  on the  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  contributions  plus  actual
     earnings thereon is based on years of continuous  service. A participant is
     fully 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) the 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 five
     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
     Forfeited balances of terminated participants' non-vested accounts are used
     to reduce  future  Company  contributions.  At  December  31, 1998 and 1997
     forfeited non-vested accounts totaled $66,474 and $38,416, respectively.

     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.

     Investment Options
     Participants are able to allocate their  contributions  among the following
     investment options:

     Vanguard  Balanced Index Fund: Seeks to provide income and long-term growth
     of capital and income by dividing its assets between indexed  portfolios of
     stocks (60 percent) and bonds (40 percent).

     Vanguard  Total Bond Market Index Fund  (formerly  the Vanguard  Bond Index
     Fund - Total  Bond  Market  Portfolio):  Seeks to  provide a high  level of
     interest  income by  attempting to match the  performance  of the unmanaged
     Lehman Brothers  Aggregate Bond Index, a widely  recognized  measure of the
     entire taxable U.S. bond market.

     Crown Cork & Seal Fixed  Income  Fund:  Seeks to preserve  the value of the
     original  investment  and  provide  an  attractive  level  of  interest  by
     investing  primarily in investment  contracts issued by insurance companies
     and banks and other types of fixed principal investments. It is designed to
     maintain a constant $1.00 share value.

 2.  Summary of Accounting Policies

     The following  accounting  policies,  which conform with generally accepted
     accounting  principles,  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  generally
     accepted  accounting  principles  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 and the 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.  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.

     Payment of Benefits
     Benefits are recorded when paid.

3.   Crown Cork & Seal Fixed Income Fund

     The Crown Cork & Seal Fixed Income Fund consists of  guaranteed  investment
     contracts ("GICs") and the Vanguard  Retirement Savings Trust. The GICs are
     valued at contract value, which approximates fair value. The GICs are fully
     benefit responsive.  Interest rates on GICs ranged between 4.94 percent and
     7.32  percent at  December  31, 1998 and 5.00  percent and 6.96  percent at
     December  31,  1997.  Average  yields on GICs were 5.71 percent in 1998 and
     6.07 percent in 1997. The Vanguard  Retirement  Savings Trust (the "Trust")
     is a tax-exempt  collective fund 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  share.  As the GICs  mature,  the  proceeds  are
     invested in the Vanguard Retirement Savings Trust.

 4.  Related Party Transactions

     The Plan invests in shares of registered investment companies managed by an
     affiliate of VFTC. VFTC acts as trustee for those investments as defined by
     the Plan.  Transactions in such  investments  qualify as  party-in-interest
     transactions which are exempt from the prohibited transaction rules.

 5.  Plan Expenses

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

 6.  Tax Status

     The Plan was amended and  restated,  effective  January 1, 1994,  to comply
     with all  provisions  of the  Internal  Revenue  Code (IRC) and ERISA.  The
     Committee has received a favorable  determination  letter from the Internal
     Revenue Service (IRS) dated February 22, 1996, and accordingly, the Plan is
     not subject to federal or local  income  taxes.  The Plan has been  amended
     since receiving the determination  letter.  However, the Plan administrator
     and the  Plan's  tax  counsel  believe  that  the Plan is  designed  and is
     currently  being operated in compliance  with the applicable  provisions of
     the Internal Revenue Code.

 7.  Insurance Company Seizure

     On August 11, 1994,  regulators in both the United States and Canada seized
     control of Confederation Life Insurance  Company.  These actions were taken
     to prevent the  possibility of massive  demands for cash following a failed
     business  combination.  At the time of the seizure, the Plan's Fixed Income
     Fund included an investment  contract  with a value of  approximately  $4.8
     million.  The recognition of interest income was suspended  coincident with
     the seizure on August 11, 1994. On October 23, 1996,  regulators approved a
     plan of  rehabilitation  and a  liquidation  order for  Confederation  Life
     Insurance  Company.  In accordance  with the  provisions of this plan,  the
     assets subject to seizure were  distributed to contract  holders (i.e., the
     Plan) under a variety of payment  options.  During 1997,  the Plan received
     100 percent of the original frozen assets plus $693,877 of interest.  These
     funds were  subsequently  transferred  out to other  investment  options in
     accordance with the participants' elections.
