                       Report of Independent Accountants


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

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 for
Employees of Golden Aluminum (the "Plan") at December 31, 1999 and 1998, 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.
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,  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.

As  explained  in Note 1, the Plan  merged  with and into the Crown  Cork & Seal
Company, Inc. 401(k) Retirement Savings Plan effective December 31, 1999.

Crown Cork & Seal Company, Inc.
401 (k) Retirement Savings Plan for Employees of Golden Aluminum
Notes to Financial Statements
- --------------------------------------------------------------------------------

NOTE 1 - DESCRIPTION OF PLAN
The  following  description  of  the  Crown  Cork & Seal  Company,  Inc.  401(k)
Retirement  Savings Plan for Employees of Golden Aluminum (the "Plan")  provides
only general  information.  Participants should refer to the Plan document for a
more complete description of the Plan's provisions.

On  December  31,  1999,  the Plan  merged  with and into the Crown  Cork & Seal
Company, Inc. 401(k) Retirement Savings Plan (the "401(k) Plan").

General
The Plan  commenced  operations on March 1, 1997 and was a defined  contribution
plan  covering  eligible  full-time  employees of Golden  Aluminum  Company (the
"Company") who had one year of service and were age eighteen or older.  The Plan
was subject to provisions of the Employee Retirement Income Security Act of 1974
("ERISA").

Contributions
Each  year,  participants  were able to  contribute  up to 17 percent of pre-tax
annual  compensation,  as  defined in the Plan.  Participants  were also able to
contribute an amount  representing  distributions  from other qualified  defined
benefit or  contribution  plans.  Participants  direct the  investment  of their
contributions into various investment options,  as listed,  offered by the Plan.
The Company  contributed 50 percent of the first 6 percent of base  compensation
that a  participant  contributed  to  the  Plan.  Additional  amounts  could  be
contributed  at the option of the Company's  board of  directors.  Contributions
were subject to certain limitations.

Participant Accounts
Each participant's account was credited with the participant's  contribution and
allocations  of (a) the  Company's  contributions  and, (b) Plan  earnings,  and
charged with an allocation of administrative expenses (Note 5). Allocations were
based on participant  earnings or account balances,  as defined.  The benefit to
which a participant was entitled was the benefit that could be provided from the
participant's vested account.

Vesting
Participants  were immediately  vested in their  contributions and the Company's
contributions plus actual earnings thereon.

Participant Loans
Participants  were able to 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 were treated as a transfer to (from) the investment
fund from (to) Participant  loans.  Loan terms ranged from 1-5 years or up to 10
years for the  purchase of a primary  residence.  The loans were  secured by the
balance in the  participant's  account and bore interest at a rate  commensurate
with a prevailing  commercial rate as determined by the Benefit Plans Committee.
Principal and interest were paid ratably through monthly payroll deductions.

Payment of Benefits
On termination of service due to death, disability or retirement,  a participant
was able to 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 not to exceed 10 years. For termination of
service due to other reasons, a participant was able to receive the value of the
vested interest in his or her account as a lump-sum distribution.

Investment Options
During the plan years ending December 31, 1999 and 1998,  participants were able
to allocate their contributions among the following investment options:

         Vanguard 500 Index Fund:  Seeks to provide  long-term growth of capital
         and income from dividends by holding all of the 500 stocks that make up

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES
The following  accounting  policies,  which conform with  accounting  principles

Financial Statement Presentation
The  plan  adopted  Statement  of  Position  ("SOP")  99-3,  Accounting  for and
Reporting of Certain  Defined  Contribution  Benefit Plan  Investments and Other
Disclosure Matters. Certain reclassifications of the 1998 amounts have been made
to  conform  to the 1999  presentation  in  accordance  with SOP 99-3.  This SOP
eliminated  the  previously  required  reporting  of  changes  in net  assets by
investment option for participant directed investments.

Use of Estimates
The  preparation  of  financial   statements,   in  conformity  with  accounting
principles generally accepted in the United States,  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  were  stated at fair value,  except for its  investment
contracts which were valued at contract value,  which  approximates  fair value.
Shares of registered  investment  companies  were valued at quoted market prices
which  represented  the net asset value of shares held by the Plan at  year-end.
The Company stock fund was 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 were valued at net asset value at year-end.

The  Company's  fixed income fund  consisted  of  investment  contracts  and the
Vanguard Retirement Savings Trust. Contract value of the contracts  approximates
their fair  value  because  the  contracts  were  benefit  responsive.  As these
investment  contracts  matured,  the  proceeds  were  invested  in the  Vanguard
Retirement Savings Trust, which invests primarily in investment contracts. Units
of the Vanguard  Retirement  Savings Trust were valued at the net asset value of
units held by the Plan at year-end.

Participant loans were valued at cost which approximates fair value.

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

Payment of Benefits
Benefits were recorded when paid.

NOTE 3 - INVESTMENTS
During  1999 and 1998,  the Plan's  investments  (including  gains and losses on
investments  bought  and sold,  as well as held  during  the  year)  appreciated
(depreciated) in value as follows:

                                                 ----               ----

                                              ---------          ---------
                                              $  93,071          $  70,778
                                              =========          =========

All investment options were participant-directed.
