PAGES 59 THROUGH 67 OF THE PROXY STATEMENT/PROSPECTUS INCLUDED IN AMENDMENT NO.
2 TO WATSON'S S-4, AS FILED WITH THE SEC ON JULY 28, 2000.

           UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

     The following unaudited pro forma condensed combined financial statements
are based on the historical consolidated financial statements of Watson and
Schein, combined and adjusted to give effect to the proposed acquisition of
Schein by Watson. The acquisition is being completed in a two-tiered
transaction, as described below:

     - In the first tier of the transaction, WS Acquisition Corp. purchased for
     cash 26,068,469 shares of Schein common stock for $19.50 per share.

     - Subsequent to the consummation of the first tier of the transaction and
     pursuant to the merger agreement, each remaining outstanding share of
     Schein common stock will be converted into the right to receive a fraction
     of a share of Watson common stock that is based upon the average of the
     closing price of a share of Watson common stock on the New York Stock
     Exchange for the ten consecutive trading days ending on the trading day two
     trading days prior to the date of the special meeting of Schein
     stockholders called to approve and adopt the merger agreement (the Watson
     average stock price). However, if the Watson average stock price is less
     than $37.82, Watson may, at its sole discretion, exchange cash, stock or a
     combination thereof, as set forth in the merger agreement, to acquire the
     remaining outstanding shares of Schein common stock. The second tier of the
     acquisition is expected to close in late August 2000. Since the number of
     shares to be issued in the second tier of the acquisition will not be known
     until the last business day prior to the special meeting, the unaudited pro
     forma condensed combined financial statements have been prepared using an
     exchange ratio of 0.50661 based on the average trading price of Watson's
     common stock for the five business day period from May 23, 2000 to May 30,
     2000 (two business days prior and subsequent to the announcement of the
     acquisition) of $45.40.

     For purposes of the unaudited pro forma condensed combined financial
statements, the term "acquisition" includes both tier one and tier two of the
proposed transaction. The following unaudited pro forma condensed combined
statements of operations for the three months ended March 31, 2000 and the year
ended December 31, 1999 give effect to the acquisition as if it had occurred at
the beginning of each period presented. The unaudited pro forma condensed
combined statement of operations for the three months ended March 31, 2000 was
prepared based upon the unaudited consolidated statements of income of Watson
for the three months ended March 31, 2000 and of Schein for the three months
ended March 25, 2000. The unaudited pro forma condensed combined statement of
operations for the year ended December 31, 1999 was prepared based upon the
consolidated statements of income of Watson for the year ended December 31, 1999
and of Schein for the year ended December 25, 1999.

     The following unaudited pro forma condensed combined balance sheet as of
March 31, 2000 gives effect to the acquisition as if it had occurred on such
date and was prepared based on the consolidated balance sheets of Watson as of
March 31, 2000 and of Schein as of March 25, 2000.

     These unaudited pro forma condensed combined financial statements should be
read in conjunction with the Watson and Schein audited consolidated financial
statements and unaudited interim consolidated financial statements, including
the notes thereto, which are included in Watson's Annual Report on Form 10-K for
the year ended December 31, 1999, Watson's Quarterly Report on Form 10-Q for the
quarter ended March 31, 2000, Schein's Annual Report on Form 10-K for the year
ended December 25, 1999 and Schein's Quarterly Report on Form 10-Q for the
quarter ended March 25, 2000, which are incorporated by reference in this proxy
statement/prospectus.

     The unaudited pro forma adjustments are based upon information set forth in
this proxy statement/prospectus and certain assumptions as described in the
notes to the unaudited pro forma condensed combined financial statements.
Watson's management believes that the pro forma assumptions are reasonable under
the circumstances.

     The unaudited pro forma condensed combined financial statements do not
reflect any incremental direct costs, including a significant restructuring
charge management expects to record in connection with the acquisition, or
potential cost savings which are expected to result from the consolidation of
certain operations of Watson and Schein. Accordingly, the unaudited pro forma
condensed combined financial statements are not necessarily indicative of the
results of operations or financial position of the combined company that would
have occurred had the acquisition occurred at the beginning of each period
presented or on the date indicated, nor are they necessarily indicative of
future operating results or financial position.

     The acquisition will be accounted for by the purchase method of accounting.
Accordingly, Watson's total cost to acquire all of the outstanding shares of
Schein common stock (the "purchase consideration"), estimated to be
approximately $800 million assuming a Watson average stock price of $45.40 and
including estimated direct transaction costs of $20 million, will be allocated
to the assets acquired and liabilities assumed according to their respective
fair values, with the excess purchase consideration being allocated to goodwill.
The total cost to acquire Schein is subject to change, to the extent that
fluctuations in the market value of Watson common stock cause the Watson average
stock price to change. A change in the Watson average stock price may result in
a change in goodwill and related amortization expense. The final allocation of
the purchase consideration is dependent upon certain valuations and other
studies that have not progressed to a stage where there is sufficient
information to make such an allocation in the accompanying unaudited pro forma
condensed combined financial statements.

     Accordingly, the purchase price allocation adjustments made in connection
with the development of the unaudited pro forma condensed combined financial
statements are preliminary and have been made solely for the purpose of
developing such unaudited pro forma condensed combined financial statements.

        The unaudited pro forma condensed combined financial statements reflect
the conversion of each outstanding share of Schein common stock, including the
settlement of certain benefit plans, into cash and/or shares of Watson, as
follows (in thousands):

                                                                ============
</TABLE>

(i)    As of March 25, 2000, there were approximately 32,984,000 shares of
       Schein common stock outstanding. Additionally, there were approximately
       7,354,000 stock options outstanding under Schein's existing stock option
       plans. The total purchase consideration in the acquisition will depend
       upon the number of Schein stock options that are exercised prior to the
       closing of the acquisition, as further discussed below.

      The accompanying unaudited pro forma condensed combined financial
      statements take into consideration the purchase of 26,068,469 shares of
      common stock of Schein after completion of the tender offer in July 2000,
      at a cash price of $19.50 per share. It is assumed that as part of the
      second tier of the transaction, approximately 11,500,000 shares of Schein
      common stock (the remaining shares of Schein common stock outstanding as
      of March 25, 2000 and the stock options assumed to be exercised prior to
      the closing date, as further described in the following paragraph) are
      exchanged using the exchange ratio specified in the merger agreement based
      on the average Watson common stock trading price for the five business day
      period from May 23, 2000 to May 30, 2000 (two business days prior and
      subsequent to the announcement of the acquisition) of $45.40, thereby
      resulting in each share of Schein common stock being converted into the
      right to receive a fraction of a share of Watson common stock valued at
      $23.00. The value of the merger consideration per share of Schein common
      stock will be increased proportionately above $23.00 if the Watson average
      stock price is greater than $54.52 per share, up to a maximum value of
      $26.50 where the Watson average stock price is $62.82 per share or higher.

      Conversely, the value of the purchase consideration will be decreased
      proportionately below $23.00, if the Watson average stock price is less
      than $44.61 per share down to a minimum value of $19.50 where the Watson
      average stock price is $37.82 per share or lower. At this minimum value of
      $19.50, Watson would have the option to pay the purchase consideration in
      cash, in stock or a combination thereof.

      As a result of the acquisition, options related to Schein's existing stock
      option plans will either 1) become fully vested and the employees will
      have the ability to exercise the related options prior to the effective
      time of the merger (stock options not exercised prior to the effective
      time of the merger will be terminated); or 2) be exchanged for Watson
      stock options in accordance with the appropriate exchange ratio set forth
      in the merger agreement. For purposes of preparing these unaudited pro
      forma condensed combined financial statements, it is assumed that all
      employees who hold stock options that will terminate if not exercised
      prior to the effective time of the merger, will exercise their stock
      options. The number of such options that are expected to be exercised is
      4,587,000. Management considers this assumption to be reasonable based on
      the fact that substantially all of the options have a current exercise
      price which is less than the average market price of a share of Schein
      common stock and the options are subject to accelerated vesting terms
      which are triggered as a result of this acquisition.

(ii)  Estimated merger transaction costs of $20 million relate principally to
      investment banking fees, legal, accounting, printing and other costs
      associated with the merger.

(iii) The portion of the purchase price allocated to in-process research and
      development ("IPR&D") represents the valuation of acquired,
      to-be-completed research projects. As such, the amount that is determined
      to be IPR&D will be charged to expense at the date of acquisition. The
      independent IPR&D valuation has not been completed as of the date these
      unaudited pro forma condensed combined financial statements were prepared
      and therefore the final amount of IPR&D to be charged to expense as part
      of this acquisition is not known. However, based on a preliminary
      assessment, it is expected that the IPR&D charge will be between $60 - $80
      million. For purposes of preparing these unaudited pro forma condensed
      combined financial statements, an IPR&D charge of $60 million has been
      assumed. If the final IPR&D charge were to increase by $10 million, it
      would have the effect of decreasing annual amortization expense by $0.5
      million.

(iv)  For purposes of preparing the unaudited pro forma condensed combined
      financial statements, the estimated excess of purchase consideration over
      net tangible assets acquired as of March 31, 2000 of $607.3 million is
      being amortized on a straight-line basis over

                                       52
<PAGE>   7

      an estimated average period of 20 years at a rate of $30.4 million per
      year. Management believes that a portion of this amount will be allocated
      to product rights with estimated useful lives up to twenty years.
      Management believes that the remaining balance will be allocated to
      goodwill with an estimated useful life of twenty to twenty-five years.
      After consummation of the acquisition, Watson will utilize the valuations
      and other studies to make a final allocation of the purchase
      consideration, including allocation to tangible assets and liabilities,
      identifiable intangible assets and goodwill. As a result of this final
      allocation, the amount of the excess of purchase consideration over net
      tangible assets acquired and the average amortization period may be
      different from what has been assumed in the preparation of these unaudited
      pro forma condensed combined financial statements. On an on-going basis,
      Watson will perform periodic reviews of the goodwill and other intangible
      assets arising from the acquisition to ensure that they are carried at
      recoverable amounts in the light of current business conditions.

      The Schein pro forma net tangible assets as of March 25, 2000 include cash
of $73.0 million and an income tax benefit of $7.5 million arising in connection
with the assumed exercise of Schein stock options as discussed in Note (i)
above.

      Certain amounts in the historical consolidated financial statements of
Watson and Schein have been reclassified to conform to the unaudited pro forma
condensed combined financial statement presentation. No adjustments are
necessary to eliminate intercompany transactions and balances in the unaudited
pro forma condensed combined financial statements as there were no intercompany
transactions or balances.

      Pro forma adjustments giving effect to the acquisition in the unaudited
pro forma condensed combined statements of operations reflect the following:

          (a) Amortization of the excess of the purchase consideration over net
      tangible assets acquired on a straight-line basis over 20 years. Refer to
      Note (iv) above.

          (b) The total amount of funds required by Watson is estimated to be
      approximately $800 million to (a) consummate the acquisition (including
      direct transaction costs of $20 million and fees related to the new bank
      facility of $11.4 million); (b) refinance certain existing indebtedness of
      Schein in the total amount of $220.6 million; and (c) finance immediate
      working capital needs of Schein. For purposes of preparing these unaudited
      pro forma condensed combined financial statements, it is assumed that
      Watson would use $250 million of cash on hand and new borrowings to fund
      this acquisition. The incremental interest expense resulting from the new
      borrowings is as follows (in thousands):

               For purposes of preparing the unaudited pro forma condensed
          combined financial statements, it is assumed that Watson will incur
          $11.4 million of deferred financing costs which will be amortized
          using a method which approximates the effective interest method over
          the expected average term of the associated financing agreements or
          five years. The incremental interest expense has been calculated based
          on an assumed interest rate of 9.08%. A change of 1/8 of 1% in the
          assumed interest rate will change annual interest expense after tax by
          $0.4 million.

          (c) Income tax effect of pro forma adjustments.

          (d) Earnings per share calculations are based on the weighted average
      number of shares of Watson common stock and common equivalent shares
      outstanding for each period presented, including the shares of Watson
      assumed to be issued in connection with the acquisition as if they had
      been issued at the beginning of each period presented. In addition,
      options to purchase 2,767,000 shares of Schein common stock are expected
      to be converted into options for Watson common stock and as such have been
      included in the calculation of the diluted weighted average number of
      shares as if they had been outstanding at the beginning of each period
      presented for purposes of calculating the pro forma earnings per share.
      Earnings per share will differ according to the number of Watson shares
      ultimately issued in connection with this acquisition. The earnings per
      share calculations are also subject to change depending on the number of
      Schein stock options exercised as discussed in Note (i) above.

          (e) The historical financial statements of Watson include the
following significant non-recurring items:

          -    During the year ended December 31, 1999 and the three months
               ended March 31, 2000, Watson sold 2.2 million (adjusted to
               reflect Andrx' April 2000 two-for-one stock split) and 4.2
               million shares (as adjusted to reflect the stock split),
               respectively, of Andrx Corporation stock on the open market for
               $54.6 million and $182.2 million, respectively, recording pre-tax
               gains of $44.3 million and $166.9 million, respectively.

          The historical financial statements of Schein include the following
significant non-recurring items:

          -    As a result of certain regulatory matters at Schein's sterile
               dosage facilities, Schein recorded a restructuring charge of
               $87.0 million in 1999, as further discussed in Schein's audited
               consolidated financial statements for the year ended December 25,
               1999 which are incorporated by reference in this proxy
               statement/prospectus.

        Pro forma adjustments giving effect to the acquisition in the unaudited
        pro forma condensed combined balance sheet reflect the following:

          (a) The net decrease in cash is comprised of the estimated cash used
          to fund a portion of the purchase consideration offset by the cash
          proceeds from the assumed exercise of the Schein stock options, as
          further discussed in Note (i) above.

          (b) Excess of purchase consideration over net tangible assets acquired
          as a result of this acquisition (refer to Note (iv) above).

          (c) Estimated deferred financing costs to be amortized using a method
          which approximates the effective interest method over the estimated
          average term of the associated financing agreements or five years.

          (d) New borrowings to (i) finance a portion of the purchase
          consideration; (ii) refinance existing Schein debt as of March 25,
          2000; (iii) pay for direct transaction costs and fees related to the
          new bank facility; and (iv) provide a working capital loan to Schein
          in the amount of $40 million for the specific purposes set forth in
          the merger agreement.

          (e) Watson common stock issued in exchange for a portion of the shares
          of Schein common stock acquired.

          (f) To reflect the estimated IPR&D charge, as further discussed in
          Note (iii) above. This charge has been excluded from the unaudited pro
          forma condensed combined statements of operations due to the
          nonrecurring nature of this item.

          (g) To reflect the income tax benefit related to the assumed exercise
          of Schein stock options, as further discussed in Note (i) above.

          (h)  Elimination of Schein's stockholders' equity.
