REPORT OF INDEPENDENT AUDITORS

Board of Directors

Reynolds Metals Company

    We have audited the accompanying combined balance sheets of North 
American Can Operations (a component of Reynolds Metals Company) as defined 
in Note 1 (the "Operation") as of December 31, 1997 and 1996, and the related 
combined statements of income and cash flows for each of the three years in 
the period ended December 31, 1997. These financial statements are the 
responsibility of the Operation's management. Our responsibility is to 
express an opinion on these combined financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing 
standards. Those standards 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. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present 
fairly, in all material respects, the combined financial position of the 
Operation, as defined in Note 1, at December 31, 1997 and 1996, and the 
combined results of their operations and their cash flows for each of the 
three years in the period ended December 31, 1997, in conformity with 
generally accepted accounting principles.

                         NORTH AMERICAN CAN OPERATIONS
                    (A COMPONENT OF REYNOLDS METALS COMPANY)

                     NOTES TO COMBINED FINANCIAL STATEMENTS

                     (IN THE TABLES, DOLLARS ARE MILLIONS)

1. BASIS OF PRESENTATION
 
    North American Can Operations is a component of Reynolds Metals Company 
("Reynolds") that primarily produces aluminum beverage cans and ends. The 
North American Can Operations (the "Operation") consist of 15 can and end 
plants in the U.S. and a can plant in Puerto Rico.
 
    The accompanying special-purpose combined financial statements have been 
prepared for the purpose of complying with the rules and regulations of the 
Securities and Exchange Commission for inclusion in a registration statement 
of Ball Corporation. They have been prepared on a historical cost basis from 
the books and records of the Operation and Reynolds on the basis of 
established accounting methods, practices, procedures and policies (see Note 
2) and the accounting judgments and estimation methodologies used by the 
Operation and Reynolds.
 
    The combined statement of income includes all items of revenue and income 
generated by the Operation, all items of expense directly incurred by it and 
expenses charged or allocated to it by Reynolds in the normal course of 
business. In addition, certain Reynolds corporate expenses were allocated by 
Reynolds to the Operation for the sole purpose of preparing these 
special-purpose combined financial statements. For additional information 
concerning expenses charged or allocated to the Operation by Reynolds, see 
Note 3.
 
    The Operation's results have been included in Reynolds' combined U.S. 
federal and applicable state income tax returns. The amount of taxes payable 
or receivable due to/from Reynolds for 1997, 1996 and 1995 is included as a 
component of Owner's Equity and equals the current provision for taxes (see 
Note 7). The provision for income taxes, the related assets and liabilities 
and the disclosures in the footnotes are presented as if the Operation had 
filed separate tax returns and are in accordance with Statement of Financial 
Accounting Standards No. 109, "Accounting for Income Taxes."
 
    The debt of the Operation consists of obligations that are specifically 
identifiable with associated capital expenditures of the Operation. No other 
debt of Reynolds (or related interest expense) has been allocated to the 
Operation.
 
    Because of the special purpose of the Operation's combined financial 
statements and the significant related party transactions (as described in 
Note 3), these special-purpose combined financial statements may not 
necessarily be indicative of the combined financial position, results of 
operations or cash flows that would have resulted if the Operation had been 
operated as a separate entity. Management believes that the accounting 
judgments, estimations and allocations made in preparing these 
special-purpose combined financial statements were reasonable.

2. ACCOUNTING POLICIES

PRINCIPLES OF COMBINATION

    These special-purpose combined financial statements include the accounts 
of the Operation after eliminating profits and losses on transactions within 
the Operation.

REVENUE RECOGNITION

    Revenues are recognized when products are shipped and ownership risk and 
title pass to the customer.



2. ACCOUNTING POLICIES (CONTINUED)

INVENTORIES

    Inventories are stated at the lower of cost or market. Inventory costs 
were determined by the first-in, first-out method and principally consist of 
finished goods.

DEPRECIATION AND AMORTIZATION

    The straight-line method is used to depreciate plant and equipment over 
their estimated useful lives (buildings -- 10 to 40 years, machinery and 
equipment -- 5 to 20 years).

ENVIRONMENTAL EXPENDITURES

    Remediation costs are accrued when it is probable that such efforts will 
be required and the related costs can be reasonably estimated.

STATEMENT OF CASH FLOWS

    Reynolds utilizes a centralized cash management system for all of its 
domestic operations, including the Operation. Cash receipts are transferred 
to Reynolds while the cash disbursements are made by Reynolds on behalf of 
the Operation, each on a current basis. The net cash generated by the 
Operation in the combined statement of cash flows is reflected as a change in 
the Owner's Equity account.

USE OF ESTIMATES

    Generally accepted accounting principles require management to make 
estimates and assumptions that affect assets and liabilities, contingent 
assets and liabilities, and revenues and expenses. Actual results could 
differ from those estimates.

3. RELATED PARTY TRANSACTIONS

REYNOLDS' LATIN AMERICAN AFFILIATE

    The Operation sells cans to a Reynolds' affiliate that produces and 
markets cans in Latin America. The Operation sells cans to the affiliate, as 
necessary, to cover production shortages.

NET INVENTORY PURCHASES FROM REYNOLDS

    Reynolds has been a primary supplier of aluminum sheet to the Operation. 
The Operation also sells aluminum scrap to Reynolds (which is accounted for 
as a credit to aluminum sheet purchases). The following is a summary of these 
transactions (which were made at market prices) for each of the last three 
years.

    Reynolds maintains several noncontributory defined benefit pension plans 
(including the Operation, Reynolds and certain consolidated subsidiaries of 
Reynolds) that cover substantially all of the Operation's employees. Plans 
covering salaried employees provide pension benefits based on a formula. The 
formula considers length of service and earnings during years of service. 
Plans covering hourly employees generally provide a specific amount of 
benefits for each year of service.

    Reynolds also maintains postretirement benefits plans (including the 
Operation, Reynolds and certain consolidated subsidiaries of Reynolds) that 
provide most of the Operation's retired employees with health care and life 
insurance benefits. Substantially all employees may become eligible for these 
benefits if they work for the Operation until retirement age.

    The Operation recognizes employee benefit costs based on allocations from 
Reynolds. These allocations were determined in a fair and equitable manner 
and have been consistently applied to the Operation and to Reynolds' other 
operations. Information system usage is charged based on actual computer time 
used by the Operation.

ALLOCATION OF CORPORATE SELLING, ADMINISTRATIVE AND GENERAL EXPENSES

    In addition to the operating expenses discussed above, certain Reynolds 
corporate expenses were allocated to the Operation by Reynolds for the sole 
purpose of preparing these special-purpose combined financial statements. 
These expenses were allocated to the Operation based on the relationship of 
the aggregate of the Operation's net sales, fixed assets and equity 
investments compared to that of Reynolds. These expenses amounted to $13.7 
million in 1997 ($12.1 million in 1996 and $17.3 million in 1995).

ACCOUNTS PAYABLE

    Accounts Payable -- Reynolds plant locations (net) reflects the net 
liability to Reynolds for purchases of aluminum sheet less the receivable 
from Reynolds for sales of scrap. The net liability assumes normal payment 
terms existed between Reynolds and the Operation. All other related party 
transactions are accounted for as changes to the Owner's Equity account.

4. OPERATIONAL RESTRUCTURING COSTS
 
    The operational restructuring costs for 1996 and 1995 resulted from the 
closings and modernizations of certain domestic can plants of the Operation. 
Two plants were closed as their capacities were in excess of

the Operation's customer needs. Productivity gains from modernizations within 
the Operation's can-making system and slower overall growth in the domestic 
can market lead to this rationalization. The significant components of these 
costs were as follows:

    The employee termination costs represent approximately 475 personnel 
(principally hourly employees). Included in the employee termination amount 
for 1996 is $18.9 million related to pension and other post-retirement 
liabilities. As these liabilities will be funded over time by Reynolds, the 
amounts are included as a component of Owner's Equity in the combined balance 
sheet. Most of the remaining cash requirements were paid as of the end of 
1997, with the balance ($4.6 million) to be paid in 1998.

    The asset revaluations were for assets to be sold (property, plant and 
equipment) as a result of the restructuring of operations. These assets were 
revalued to their estimated recoverable value.

6. FINANCING ARRANGEMENTS

    The Operation's debt at December 31, 1997 consists of $49.2 million of 
industrial and environmental control revenue bonds (including $41.2 million 
at the Puerto Rico can plant) and a mortgage of $5.4 million (which includes 
$0.2 million in Other current liabilities in the Combined Balance Sheet).

    The industrial and environmental control revenue bonds bear interest at a 
variable rate (averaging approximately 3.8% at December 31, 1997). These 
bonds require principal repayments in a lump sum in 2013 ($41.2 million) and 
2015 ($8.0 million). Letters of credit issued to Reynolds by banks support 
these bonds. The mortgage bears interest at a fixed rate of 10%. The mortgage 
requires principal repayments through 2009 (approximately $0.2 to $0.3 
million a year for the next five years).

    Interest expense incurred was $2.6 million in 1997 ($2.8 million in 1996 
and $3.0 million in 1995). Interest capitalized amounted to $0.5 million in 
1997 ($2.8 million in 1996 and $2.1 million in 1995).



6. FINANCING ARRANGEMENTS (CONTINUED)

    The financing arrangements contain compliance requirements, such as 
maintaining and operating the associated facilities in good repair during 
their useful lives. Upon the occurrence of certain events, including 
cessation of operation of the Puerto Rican plant, the maturities of the 
Operation's debt could be accelerated. These requirements do not inhibit 
operations or the use of fixed assets. At December 31, 1997, the Operation 
met all such compliance requirements.

    The fair value of the Operation's debt was approximately equal to book 
value at the end of 1997 and 1996.

7. TAXES ON INCOME

    The significant components of the provision for taxes on income (credit) 
were:

    Deferred income taxes reflect the net tax effects of temporary 
differences between the carrying amounts of assets and liabilities for 
financial reporting purposes and the amounts used for income tax purposes. At 
December 31, 1997, the Operation had $7.9 million (1996 -- $14.9 million) of 
deferred tax

assets and $41.8 million (1996 -- $38.9 million) of deferred tax liabilities. 
The significant components of deferred tax assets and liabilities reflected 
in the combined balance sheet are as follows:

    Included in the Operation is a corporation (Latas de Aluminio Reynolds, 
Inc.) which for all years joined in the filing of a U.S. federal consolidated 
income tax return with Reynolds and its affiliated group members. Each entity 
included in a consolidated return is severally liable for any resultant tax 
reflected on such consolidated return.

8. CONTINGENT LIABILITIES

LEGAL

    Various suits, claims and actions are pending against the Operation. In 
the opinion of management, after consultation with legal counsel, disposition 
of these suits, claims and actions, either individually or in the aggregate, 
will not have a material adverse effect on the Operation's competitive or 
financial position or its expected ongoing results of operations.

ENVIRONMENTAL

    The Operation is involved in various environmental improvement activities 
resulting from past operations including where Reynolds has been designated 
as a potentially responsible party ("PRP"), with others, at various 
Environmental Protection Agency-designated Superfund sites.

    Amounts have been recorded (on an undiscounted basis) which, in 
management's best estimate, will be sufficient to satisfy anticipated costs 
of known remediation requirements. At December 31, 1997, the accrual for 
environmental remediation costs was $8.4 million. This amount is expected to 
be spent over the next 10 to 15 years with the majority to be spent by the 
year 2002.

    Estimated environmental remediation costs are developed after 
considering, among other things, the following:

    - currently available technological solutions

    - alternative cleanup methods

    - risk-based assessments of the contamination

    - estimated proportionate share of remediation costs (if applicable)

    The Operation may also use external consultants, and consider, when 
available, estimates by other PRPs and governmental agencies and information 
regarding the financial viability of other PRPs. Based on information 
currently available, the Operation believes it is unlikely that it will incur 
substantial additional costs as a result of failure by other PRPs to satisfy 
their responsibilities for remediation costs.



8. CONTINGENT LIABILITIES (CONTINUED)

    Estimated costs for future environmental compliance and remediation are 
necessarily imprecise because of factors such as:

    - continuing evolution of environmental laws and regulatory requirements

    - availability and application of technology

    - identification of presently unknown remediation requirements

    - cost allocations among PRPs

    Further, it is not possible to predict the amount or timing of future 
costs of environmental remediation that may subsequently be determined. Based 
on information presently available, such future costs are not expected to 
have a material adverse effect on the Operation's competitive or financial 
position or its expected ongoing results of operations.

9. OTHER

MAJOR CUSTOMERS

    The Operation has two major customers. Sales to Philip Morris Companies, 
Inc. ("PM") represented 45% of customer net sales in 1997 (47% in 1996 and 
41% in 1995). The combined sales to Coca-Cola bottlers (as a group) 
represented 20% of customer net sales in 1997 (19% in 1996 and 20% in 1995). 
At December 31, 1997, receivables from PM and the Coca-Cola bottlers (as a 
group) were 21% and 10%, respectively, as a percentage of total customer 
receivables.

RESEARCH AND DEVELOPMENT

    The Operation incurred $6.1 million in research and development costs in
1997 ($7.2 million in 1996 and $6.6 million in 1995).

CONSIGNMENT INVENTORIES

    The Operation holds certain materials (principally aluminum sheet 
inventory) at its facilities on consignment from Reynolds and certain outside 
vendors. At December 31, 1997, the total value of aluminum sheet inventory on 
consignment was $23.9 million ($14.4 million at December 31, 1996). Under 
these consignment agreements, the Operation takes title to the materials at 
the time they are placed into the production process. Additionally, any 
consignment inventory held in excess of certain periods of time (whether used 
or not) becomes the Operation's inventory. Aluminum sheet inventory on 
consignment from Reynolds at December 31, 1997 totaled $18.1 million ($10.9 
million at December 31, 1996).
