Exhibit 99.3


             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

     The following pro forma consolidated financial information has been derived
by the application of pro forma adjustments to the historical consolidated
financial statements of The Lubrizol Corporation ("Lubrizol") and Noveon
International, Inc. ("Noveon") as of March 31, 2004 and for the three month
periods ended March 31, 2004 and 2003, and the year ended December 31, 2003. The
unaudited pro forma consolidated balance sheet gives effect to the proposed
acquisition of Noveon by Lubrizol and permanent financing thereof as if they had
occurred on March 31, 2004. The unaudited pro forma consolidated statements of
income give effect to the proposed acquisition and permanent financing thereof
as if they had occurred on January 1, 2003. The permanent financing is expected
to replace temporary bridge loan financing, which is only expected to be
outstanding approximately three months. Accordingly, the bridge loan financing
is not reflected in the accompanying pro forma consolidated financial
information, except for the estimated cost of the temporary financing (issuance
and interest costs) which is reflected as a charge against pro forma
shareholders' equity, net of the effect of income taxes, in the March 31, 2004
unaudited pro forma consolidated balance sheet.

     Assumptions underlying the pro forma adjustments necessary to fairly
present this pro forma information are described in the accompanying notes,
which should be read in conjunction with this pro forma consolidated financial
information. The pro forma adjustments described in the accompanying notes have
been made based on available information and, in the opinion of management, are
reasonable. The pro forma consolidated financial information should not be
considered indicative of actual results that would have been achieved had the
transactions occurred on the respective dates indicated and do not purport to
indicate balance sheet data or results of operations as of any future date or
for any future period. Lubrizol cannot assure you that the assumptions used in
the preparation of the pro forma consolidated financial information will prove
to be correct.

     The acquisition of Noveon by Lubrizol will be accounted for as a purchase
in conformity with Statement of Financial Accounting Standards ("SFAS") No. 141,
"Business Combinations," with intangible assets recorded in accordance with SFAS
No. 142, "Goodwill and Other Intangible Assets." The total cost of the
acquisition will be allocated as a change in basis to the tangible and
intangible assets acquired and liabilities assumed based on their respective
fair values as of the date of the acquisition. The excess of the purchase price
over the historical basis of the net assets to be acquired has been allocated in
the accompanying pro forma financial information based on preliminary valuation
estimates and certain assumptions that management believes are reasonable. The
actual allocation will be subject to the valuation of Noveon's assets and
liabilities as of the date the merger is finalized and, therefore, that
allocation and the resulting effect on income from operations may differ from
the pro forma amounts included herein. In addition, in accordance with the
provisions of SFAS No. 142, no amortization of indefinite-lived intangible
assets or goodwill will be recorded.

     The unaudited pro forma consolidated statements of income do not include
the cumulative effect of the change in accounting resulting from Noveon's
adoption, in 2003, of SFAS No. 143, "Accounting for Asset Retirement
Obligations", and also do not include certain non-recurring costs and charges
that Lubrizol will record on or following the closing of the acquisition. These
one-time charges include a non-cash charge for the manufacturing profit added to
inventory under purchase accounting which will be charged to cost of sales as
this inventory is sold after closing, the costs expected to be incurred for
temporary bridge financing of the acquisition from the closing through the date
the bridge financing is replaced with permanent financing and the costs
associated with Noveon integration activities. In addition, the unaudited pro
forma consolidated statements of income do not include any cost reduction
opportunities expected to result from commercial and technical synergies between
Lubrizol and Noveon.

(1) The amounts in this column represent the reported amounts for Lubrizol as of
March 31, 2004.

(2) The amounts in this column represent the reported amounts for Noveon as of
March 31, 2004.

(3) The amounts in this column represent the adjustments necessary to give pro
forma effect to the proposed acquisition of Noveon. The adjustments are based on
a preliminary allocation of the purchase price, which is expected to be
finalized within one year of the acquisition date.

          (a)  Set forth below are the estimated sources and uses of funds
               pertaining to the acquisition. The sources and uses below assume

               (1) Represents the permanent financing that is expected to be
               issued to replace a $2.1 billion 364 day temporary bridge loan
               bearing interest at LIBOR plus 1.25%. The temporary bridge loan
               is expected to be replaced with permanent financing in the form
               of a term loan, debt securities and equity issuance (see notes 2
               through 5 below) within three months of the  acquisition.

               (2) Lubrizol's revolving credit facilities are expected to be
               increased from $350 million to $500 million in connection with
               the acquisition, none of which are expected to be utilized to
               provide funds for the acquisition.

               (3) Represents the amount expected to be drawn on a $575 million
               term loan facility bearing interest at LIBOR plus 1.25% to
               provide funds to repay the temporary bridge financing. The loan
               is expected to be due in quarterly installments through 2009.

               (4) Represents the anticipated issuance of unsecured debt
               securities bearing interest at approximately 6.5% per annum to
               provide funds to repay the temporary bridge financing. The debt
               securities are expected to be comprised of three tranches; $400
               million maturing in 2009, $400 million maturing in 2014 and $300
               million maturing in 2034.

               (5) Represents the net proceeds (net of approximately $17 million
               of estimated issuance costs) expected to be received from the
               issuance of additional common shares of Lubrizol to provide funds
               to repay the temporary bridge financing.

               (6) Represents the portion of existing cash balances that are
               expected to be used to pay the costs and expenses directly
               associated with the acquisition.

               (7) Represents the estimated merger consideration and is net of
               $32.2 million of Noveon's estimated transaction costs, change in
               control and other payments specified in the Agreement and Plan of
               Merger.

               (8) Includes accrued interest of $4.9 million, $71.5 million of
               estimated prepayment penalties and $9.6 million to cancel
               outstanding interest rate swap agreements associated with the
               indebtedness being repaid.

               (9) Includes $57.4 million of costs expected to be incurred by
               Lubrizol directly associated with the acquisition and obtaining
               the related debt (temporary and permanent) financing and $35.5
               million of costs expected to be incurred by Noveon directly
               associated with the acquisition (including the $32.2 million of
               costs offset against the common stock acquisition consideration
               described in note 7 above)

               recognized with respect to stock options that will be cancelled
               in connection with the acquisition, the prepayment penalties that
               will be incurred and the write-off of unamortized debt issuance
               costs that will result from the early extinguishment of Noveon's
               existing indebtedness, management bonuses and change in control
               payments, and certain professional and advisory fees expected to
               be incurred by Noveon as a result of the acquisition.

               recognition of approximately $33.5 million of deferred taxes on
               the undistributed earnings of Noveon's foreign subsidiaries and
               the reversal of approximately $50.0 million of Noveon's deferred
               tax asset valuation allowances reflecting the fact that Noveon's
               inclusion within the Lubrizol U.S. consolidated group for income
               tax purposes subsequent to the acquisition is expected to result
               in the deferred tax assets being utilized to offset the taxable
               income of the U.S. consolidated group.

          against the deferred tax assets recorded for Noveon's net operating
          loss carryforwards reflecting the fact that a portion of the net
          operating loss carryforwards as of the acquisition date are expected
          to be utilized to offset Lubrizol's income taxes payable.

          approximately $12.3 million of interest expense expected to be
          incurred during the 3 month period the bridge loan is expected to be
          outstanding.

NOTES TO UNAUDITED PRO FORMA CONSOLIDATED STATEMENTS OF INCOME

(1)  The amounts in this column represent the reported results for Lubrizol for
     the applicable period.

(2)  The amounts in this column represent the reported results for Noveon for
     the applicable period and do not include the cumulative effect of Noveon's
     change in the method used to account for asset retirement obligations in
     2003 pursuant to the implementation of SFAS No. 143.

(3)  The amounts in this column represent the adjustments necessary to give pro
     forma effect to the proposed acquisition of Noveon. Adjustments (a), (b)
     and (c) are based on a preliminary allocation of the purchase price, which
     is expected to be finalized within one year of the acquisition date.

          (a) The pro forma statements of income do not reflect the estimated
          $20.0 million ($13.0 million after tax) one-time, non-cash charge to
          cost of sales that will be recognized upon the sale of the inventory
          to which capitalized manufacturing profit is added under purchase
          accounting.

          (b) Represents the amount of management fees charged to Noveon by
          related parties that will cease as a result of the acquisition.

          (c) This adjustment represents the change in amortization expense
          resulting from the amortization of the additional intangible assets
          recorded in connection with the acquisition using the straight-line
          method based on the following (dollars in millions):

          (e) The adjustment to interest expense reflects the following (in

                    (1) Reflects commitment fees of .20% on the estimated $500
                    million of average undrawn balance under the revolving
                    credit facility less the commitment fees included in the
                    historical results of operations.

          A .25% increase or decrease in the weighted average interest rate
          applicable to Lubrizol's indebtedness outstanding under the new term
          loan facility and the debt securities would change the pro forma
          interest expense by $1.0 million, $4.2 million and $1.0 million for
          the three month period ended March 31, 2004, year ended December 31,
          2003 and the three month period ended March 31, 2003, respectively.

          (f) This adjustment represents the tax effect of pro forma adjustments
          to income before income taxes and is based on the estimated applicable
          statutory tax rates.

          (g) This adjustment represents the estimated reduction in Lubrizol's
          historical U.S. tax benefits associated with extraterritorial income
          and foreign tax credits resulting from the acquisition of Noveon.

          (h) This adjustment represents the elimination of the charge/credit
          included in Noveon's historical provision for income taxes resulting
          from the change in Noveon's deferred tax asset valuation allowance
          pertaining to its domestic, federal income taxes that is expected to
          be reversed in connection with the acquisition, reflecting the fact
          that Noveon's inclusion within the Lubrizol U.S. consolidated group
          for income tax purposes subsequent to the acquisition is expected to
          result in the deferred tax assets being utilized to offset the taxable
          income of the consolidated group.


(4) The amounts in this column represent the pro forma results for Lubrizol
after giving effect to the acquisition as if it had been consummated on January
1, 2003, the first day of Lubrizol's most recently completed fiscal year.
