UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA

    The Unaudited Pro Forma Condensed Combined Financial Data is based on the 
consolidated financial statements of Ball and the combined financial 
statements of Reynolds included elsewhere in this Offering Memorandum. The 
unaudited pro forma condensed combined balance sheet at March 29, 1998 is 
based on the consolidated financial statements of Ball, adjusted to give 
effect to the Transactions as if they had occurred on March 29, 1998.  The 
unaudited pro forma condensed combined statements of income for the year 
ended December 31, 1997, the three-month period ended March 29, 1998 and the 
twelve-month period ended March 29, 1998 are based on the consolidated 
financial statements of Ball and adjusted to give effect to the Transactions 
as if they had occurred on January 1, 1997. During the periods presented, 
neither Ball's nor Reynolds' statements of income included any amounts 
related to discontinued operations. Adjustments for the Transactions are 
based upon historical financial information of Ball and Reynolds and certain 
assumptions that management of Ball believes are reasonable. The Acquisition 
will be accounted for under the purchase method of accounting. Under this 
method, the purchase price has been allocated to the assets and liabilities 
acquired based on preliminary estimates of fair value. The actual fair value 
will be determined upon the consummation of the Acquisition and may vary from 
the preliminary estimates. The pro forma financial data does not necessarily 
reflect the results of operations or the financial position of Ball that 
actually would have resulted had the Transactions occurred at the date 
indicated, or project the results of operations or financial position of the 
Company for any future date or period.

    The unaudited pro forma condensed combined financial data should be read 
in conjunction with the consolidated financial statements of Ball and the 
combined financial statements of Reynolds, and the notes thereto, included 
elsewhere in this Offering Memorandum.

    (ii) the elimination of $32.4 million of interest on the existing Ball debt
    that will be repaid with proceeds of the Senior Credit Facility, Canadian
    Revolving Credit Facility and Notes; (iii) the elimination of $2.4 million
    of interest related to the Reynolds debt that will not be assumed by Ball;

    represent floating rate debt. A 1/8 of 1 percent change in the interest rate
    on that debt would result in a change in interest expense of approximately
    $1.0 million.
 
(7) Income tax expense was adjusted to reflect an effective tax rate of 39.2%,
    which is the expected statutory effective tax rate of Ball.
 
(8) Basic earnings per common share was calculated by dividing Ball historical
    or pro forma net earnings available to common shareholders by the weighted
    average common shares outstanding. Diluted earnings per common share was
    calculated by dividing Ball historical or pro forma net income, as adjusted
    for the impact of an assumed conversion of the Ball ESOP (as defined)
    preferred shares into common shares, by the weighted average common shares
    outstanding, as adjusted for the assumed exercise of dilutive stock options
    and the conversion of the ESOP preferred shares into common shares. For the
    three months ended March 29, 1998, no adjustment was made for the assumed
    conversion of the ESOP shares in the pro forma earnings per share
    calculation, as the result would have been anti-dilutive. See Ball "Notes to
    Consolidated Financial Statements."
 
(9) Three-month period ended March 31, 1998.
 
(10) Represents incremental rent expense on certain of the Company's leases as a
    result of the Financings.
 
(11) Twelve-month period ended March 31, 1998.

                                BALL CORPORATION
 
         NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED BALANCE SHEET
 
                                 MARCH 29, 1998
 
(1) As of March 31, 1998.
 
(2) These adjustments reflect the elimination from the Reynolds historical
    financial statement balances of the assets and liabilities that will not be
    purchased or assumed by Ball, as provided in the Purchase Agreement.
 
(3) The Reynolds acquisition will be accounted for using the purchase method of
    accounting. These amounts reflect the preliminary estimates of adjustments
    necessary to record the Reynolds assets acquired and liabilities assumed at
    their respective fair values, as required by Accounting Principles Board
    Opinion No. 16. The total purchase price was determined and allocated as
    follows:
 


Cash purchase price for Reynolds business.........................................................  $   746.0
                                                                                                 
Additional cash paid for working capital..........................................................       38.8
Incentive loan to RMC.............................................................................       39.0
Acquisition costs(a)..............................................................................        9.0
                                                                                                    ---------

                                                                                                    ---------
                                                                                                    ---------
 
Purchase price allocated to:
Tangible assets...................................................................................  $   613.1
Goodwill..........................................................................................      375.3
Other intangible assets...........................................................................       15.0
Liabilities.......................................................................................     (170.6)
                                                                                                    ---------
Total purchase price allocated....................................................................  $   832.8
                                                                                                    ---------
                                                                                                    ---------

 
- -----------------------------
 
    (a) Represents fees and costs directly associated with the Reynolds
       acquisition consisting primarily of investment banking, legal and other
       professional fees.
 
(4) Goodwill was adjusted to reflect: (i) the elimination of existing goodwill
    of Reynolds and (ii) the excess of purchase cost over the estimated fair
    value of the Reynolds net assets acquired and liabilities assumed, which
    amount will be amortized on a straight line basis over an estimated life of
    40 years.
 
(5) Other assets were adjusted to reflect: (i) the capitalization of $28.0
    million of financing costs that will be amortized over the life of the Notes
    and the Senior Credit Facility and (ii) the allocation of $15.0 million of
    purchase price to other intangible assets (primarily related to customer
    lists, agreements not to compete and technology licensing agreements) that
    will be amortized over an estimated life of ten years.
 
(6) Pursuant to EITF 95-3, the Company has estimated certain employee severance
    and employee relocation costs anticipated in connection with consolidation
    of the businesses.
 
(7) Long-term debt was adjusted to reflect: (i) gross proceeds of $550.0 million
    from the issuance of the Notes and additional borrowings of $326.8 million
    under the Senior Credit Facility and (ii) the reclassification of $312.7
    million of short-term debt to long-term debt.
 
(8) Represents an adjustment to reflect the estimated liability for certain
    Reynolds employee benefit obligations assumed by Ball. These obligations,
    primarily for certain pension and medical benefits, were recorded on the
    books of RMC, the seller, and not pushed down to Reynolds. All expenses
    related to these benefit plans were recorded on the books of Reynolds. A
    corresponding deferred tax asset related to this liability has also been
    established in this pro forma balance sheet.
 
(9) The adjustment reflects the elimination of the former owner's equity of
    Reynolds.
 
(10) The adjustment reflects an estimate of the non-recurring cost ($16.0
    million, net of a $6.3 million tax benefit) on refinancing Ball's existing
    borrowings under the Senior Credit Facility as a net reduction of
    shareholders' equity.
