                               AVANEX CORPORATION,
                        THE OPTRONICS DIVISION OF ALCATEL
                 AND THE OPTICAL COMPONENTS BUSINESS OF CORNING
      FOR THE THREE MONTHS ENDED SEPTEMBER 30, 2003 AND FOR THE YEAR ENDED
                                  JUNE 30, 2003



          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

                       INTRODUCTION TO UNAUDITED PRO FORMA
                    CONDENSED COMBINED FINANCIAL INFORMATION

         The following unaudited pro forma condensed combined statements of
operations for the year ended June 30, 2003 and the three months ended September
30, 2003 are based on the historical financial statements of Avanex, Alcatel's
Optronics division and the optical components business of Corning, after giving
effect to the transactions as purchases of Alcatel's Optronics division and the
optical components business of Corning by Avanex using the purchase method of
accounting, as required under the rules of the Securities and Exchange
Commission, and the assumptions and adjustments described in the accompanying
notes to the unaudited pro forma condensed combined financial information. The
unaudited pro forma condensed combined statements of operations are presented as
if the transactions had occurred on July 1, 2002.

         The unaudited pro forma condensed combined statement of operations for
the three months ended September 30, 2003 combines the historical three months
ended September 30, 2003 for Avanex, which includes two months of operations of
Alcatel's Optronics division and two months of operations of the optical
components business of Corning, and the historical one-month ended July 31, 2003
for each of Alcatel's Optronics division and the optical components business of
Corning. Since the acquisitions of Alcatel's Optronics division and the optical
components business of Corning occurred prior to September 30, 2003, no
unaudited pro forma condensed balance sheet is presented because the balance
sheet of Avanex as of September 30, 2003 includes the purchase of Alcatel's
Optronics division and the optical components business of Corning.

         Under the purchase method of accounting, the total purchase price,
calculated as described in Notes 2 and 3 to this unaudited pro forma condensed
combined financial information, is allocated to the net tangible and intangible
assets of Alcatel's Optronics division and the optical components business of
Corning acquired in connection with the transactions, based on their fair values
as of the completion of the transactions.

         These unaudited pro forma condensed combined financial statements have
been prepared based on an allocation of the purchase price of the acquired
companies to the tangible and intangible assets acquired and liabilities assumed
based on their estimated fair values. Avanex engaged an independent
third-party appraisal firm to assist it in determining the fair values of the
assets acquired and the liabilities assumed. Such valuations require management
to make significant estimations and assumptions, especially with respect to
intangible assets. Critical estimates in valuing certain intangible assets
include, but are not limited to: future expected cash flows from customer
contracts, customer lists, supply agreements, and acquired developed
technologies and patents. Management's estimates of fair value are based upon
assumptions believed to be reasonable, but which are inherently uncertain and
unpredictable. The preliminary purchase price allocation may change due to the
receipt of final valuations and completion of an assessment and formulation of
additional restructuring plans. Management continues to assess and formulate
restructuring plans to exit certain additional activities and to terminate or
relocate certain employees. These assessments are still in process and
management expects to adopt further formal restructuring plans in fiscal 2004.
Any further restructuring costs related to former Alcatel and Corning activities
will be accrued by the Company as a liability in conjunction with recording the
purchase of Alcatel and Corning, with no impact on results of operations.
Restructuring costs related to former Avanex activities will be charged to
operations.

         This unaudited pro forma condensed combined financial information
should be read in conjunction with the separate historical financial statements
and accompanying notes of Alcatel's Optronics division and the optical
components business of Corning included in a Form 8-K filed with the SEC on
September 26, 2003 and the separate historical consolidated financial statements
and accompanying notes of Avanex included in its annual report on Form 10-K for
the year ended June 30, 2003 and the Form 10-Q for the quarter ended September
30, 2003 filed with the SEC. The unaudited pro forma condensed combined
financial information is not intended to represent or be indicative of the
consolidated results of operations or financial condition of Avanex that would
have been reported had the transactions been completed as of the dates
presented, and should not be taken as representative of the future consolidated
results of operations or financial condition of Avanex.

                     NOTES TO UNAUDITED PRO FORMA CONDENSED
                         COMBINED FINANCIAL INFORMATION

1. BASIS OF PRO FORMA PRESENTATION

     On May 12, 2002, Avanex Alcatel and Corning entered into a Share
Acquisition and Asset Purchase Agreement (the "Agreement") pursuant to which
Avanex acquired:

- -    From Alcatel, all of the outstanding capital stock of Alcatel Optronics
     France SA ("Alcatel's Optronics division") by exchanging shares of Avanex
     common stock equal to the product of (i) 0.28, multiplied by (ii) the
     quotient obtained by dividing (a) that number of shares of Avanex common
     stock outstanding immediately prior to closing by (b) 0.55 (number of
     shares to be issued = 28% x the number of shares of Avanex common stock
     outstanding immediately before closing / 55%). Based upon 69,476,460 shares
     of Avanex common stock outstanding at July 31, 2003, approximately 35
     million shares of Avanex common stock were issued to Alcatel with a value
     of approximately $63 million. The average market price of Avanex's common
     stock of $1.79 was determined based on the closing price from May 8, 2003
     to May 14, 2003, which includes two trading days prior and two trading days
     subsequent to the public announcement of the transaction; and,

- -    From Corning, certain U.S. and Italian assets including specified
     inventory, long-lived assets and intellectual property (collectively "the
     optical components business of Corning"). Corning sublet its Erwin Park,
     New York facility to Avanex and transferred Corning's Milan, Italy lease
     agreement to Avanex. Avanex also assumed certain repair and warranty
     obligations. In addition, Avanex employs approximately 400 employees of the
     optical components business of Corning previously employed in the U.S. and
     Italy. The purchase price was consummated by exchanging shares of Avanex
     common stock equal to the product of (i) 0.17, multiplied by (ii) the
     quotient obtained by dividing (a) that number of shares of Avanex common
     stock outstanding immediately prior to closing by (b) 0.55 (number of
     shares to be issued = 17% x the number of shares of Avanex common stock
     outstanding immediately before closing / 55%). Based upon 69,476,460 shares
     of Avanex common stock outstanding at July 31, 2003, approximately 21
     million shares of Avanex common stock were issued to Corning with a value
     of approximately $38 million. The average market price of Avanex's common
     stock of $1.79 was determined based on the closing price from May 8, 2003
     to May 14, 2003, which includes two trading days prior and two trading days
     subsequent to the public announcement of the transaction.

     The transactions closed on July 31, 2003 and were accounted for under the
purchase method of accounting.

                                                                                                                   =======


The pro forma weighted average shares used in computing basic net income (loss)
per share for the three months ended September 30, 2003 are based on the actual
weighted average number of shares of Avanex common stock outstanding for the
quarter ended September 30, 2003 plus 12,420 shares (representing the difference
between the shares issued by Avanex in the transaction to acquire Alcatel's
Optronics division and the amount already included in the actual weighted
average number of shares of Avanex common stock outstanding for the quarter
ended September 30, 2003) and the 7,613 shares (representing the difference
between the shares issued by Avanex in the transaction to acquire the optical
components business of Corning and the amount already included in the actual
weighted average number of shares of Avanex common stock outstanding for the
quarter ended September 30, 2003).

     No weighted average diluted shares were used in the calculation of pro
forma earnings per share as the impact would have been antidilutive.

     There is no outstanding share capital in the financial statements of
Alcatel's Optronics division and the optical components business of Corning.
Therefore, basic and diluted net income (loss) per share for these entities is
not separately presented.

6. INCOME TAXES

     The pro forma combined provision for income taxes does not represent the
amounts that would have resulted had Avanex, Alcatel's Optronics division and
the optical components business of Corning filed consolidated income tax returns
during the periods presented.
