                  CORNING INCORPORATED AND SUBSIDIARY COMPANIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                (Unaudited; in millions except per share amounts)


1.   Basis of Presentation

General
-------
Corning  Incorporated  is a world-leading  provider of optical fiber,  cable and
photonic products for the  telecommunications  industry;  high-performance glass
for  computer  monitors,   television  screens  and  other  information  display
applications;  advanced optical materials for the semiconductor industry and the
scientific   community;   ceramic   substrates  for  the  automotive   industry;
specialized polymer products for biotechnology applications;  and other advanced
materials and technologies.

The unaudited  Consolidated  Financial Statements reflect all adjustments which,
in the opinion of management,  are necessary for a fair statement of the results
of  operations,  financial  position  and cash  flows  for the  interim  periods
presented.   All  such  adjustments  are  of  a  normal  recurring  nature.  The
Consolidated  Financial  Statements have been prepared pursuant to the rules and
regulations  of the Securities  and Exchange  Commission and in accordance  with
accounting  principles generally accepted in the United States of America (GAAP)
for interim financial information.

GAAP  requires  management  to make certain  estimates  and  judgments  that are
reflected in the reported amounts of assets, liabilities,  revenues and expenses
and also in the  disclosure of contingent  liabilities.  The actual  results may
differ from the estimates. Management exercises judgment and makes estimates for
allowance for bad debts, inventory  obsolescence,  product warranty,  in-process
research and development, restructuring charges, asset and goodwill impairments,
depreciation, pension and post-retirement benefits, income taxes, litigation and
other  contingencies.  Management  reviews these estimates on a systematic basis
and, if necessary,  any material  adjustments are reflected in the  consolidated
financial statements in the period that they are deemed necessary.

The results for interim periods are not necessarily indicative results which may
be expected for any other interim  period,  or for the full year.  These interim
Consolidated  Financial  Statements should be read in conjunction with Corning's
Annual Report on Form 10-K/A for the year ended December 31, 2001.

Certain amounts for 2001 were reclassified to conform with 2002 classifications.

Goodwill and Other Intangible Assets
------------------------------------
In June 2001, the Financial  Accounting  Standards Board (FASB) issued Statement
of Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other Intangible
Assets." Among other provisions,  goodwill is no longer amortized but is subject
to impairment  tests at least annually.  Corning adopted SFAS No. 142 on January
1, 2002.  Corning  completed  its  initial  impairment  review  during the first
quarter and concluded a transitional  impairment charge from the adoption of the
standard was not required.

Corning has selected the fourth quarter to conduct annual  impairment tests. The
outcome of the impairment test is primarily dependent upon the fair value of the
reporting units.  Business  conditions in the  telecommunications  industry have
deteriorated  during the year and are  depressed  such that it appears  the fair
value of Corning's  telecommunications reporting unit is currently lower than at
the benchmark  assessment date of January 2002. As part of the annual impairment
test, management is currently studying short and long-term market indicators and
alternative  growth  patterns.  Based on the work  performed to date, it appears
reasonably  possible that a portion,  but not all of the  company's  goodwill is
impaired. Management will complete the impairment test in the fourth quarter and
record any required  goodwill  impairment  charge.  The goodwill  related to the
Telecommunications  Segment is $1.9  billion at September  30, 2002.  Management
believes  there are a range of possible  outcomes and no assurance  can be given
that an  impairment  charge  will not be  required.  A charge  would  lower  the
company's  equity and could  reduce  availability  under the unused $2.0 billion
revolving  credit  facility.  See  Liquidity  and Capital  Resources for further
information.

Other New Standards Adopted
---------------------------
In August 2001, the FASB issued SFAS No. 144,  "Accounting for the Impairment or
Disposal  of  Long-Lived   Assets."  This  standard  supercedes  SFAS  No.  121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be  Disposed  Of." The  standard  retains  the  previously  existing  accounting
requirements  related to the  recognition  and  measurement of the impairment of
long-lived   assets  to  be  held  and  used  while  expanding  the  measurement
requirements  of  long-lived  assets  to be  disposed  of  by  sale  to  include
discontinued  operations.  It also expands on the previously  existing reporting
requirements  for  discontinued  operations  to include a component of an entity
that either has been  disposed  of or is  classified  as held for sale.  Corning
adopted  SFAS No. 144 on January 1, 2002.  The  adoption of SFAS No. 144 did not
have a material  impact on its  consolidated  financial  position  or results of
operations.

In April  2002,  the FASB  issued  SFAS No.  145,  which  rescinds  SFAS No.  4,
"Reporting  Gains  and  Losses  from  Extinguishment  of  Debt,"  SFAS  No.  44,
"Accounting  for  Intangible   Assets  of  Motor  Carriers"  and  SFAS  No.  64,
"Extinguishments  of Debt Made to Satisfy  Sinking-Fund  Requirements and amends
SFAS No. 13,  "Accounting  for Leases." This  statement  updates,  clarifies and
simplifies  existing accounting  pronouncements.  As a result of rescinding SFAS
No. 4 and SFAS No. 64, the  criteria in  Accounting  Principles  Bulletin No. 30
will be used to classify gains and losses from  extinguishment of debt.  Corning
adopted the reporting  guidance of SFAS No. 145 in the second quarter of 2002 in
its  accounting  for  repurchases  and  retirement  of  debt.  See Note 5 to the
Consolidated Financial Statements. The remaining provisions of SFAS No. 145 will
be adopted by Corning in fiscal year 2003.  Corning does not expect the adoption
of the  remaining  provisions  to have a  material  impact  on its  consolidated
financial position or results of operations.

New Accounting Standards
------------------------
In June 2001,  the FASB issued SFAS No. 143,  "Accounting  for Asset  Retirement
Obligations."  This standard  addresses  financial  accounting and reporting for
obligations associated with the retirement of tangible long-lived assets and the
associated asset retirement costs. Corning is required to implement SFAS No. 143
on January 1, 2003.  Corning  does not expect  this  standard to have a material
impact on its consolidated financial position or results of operations.

In June 2002,  the FASB issued SFAS No. 146,  "Accounting  for Costs  Associated
with Exit or Disposal  Activities." This standard nullifies Emerging Issues Task
Force Issue No. 94-3,  "Liability  Recognition for Certain Employee  Termination
Benefits and Other Costs to Exit an Activity  (including  Certain Costs Incurred
in a  Restructuring)."  This  standard  requires  that  a  liability  for a cost
associated with an exit or disposal activity be recognized when the liability is
incurred rather than the date of an entity's commitment to an exit plan. Corning
is required to  implement  SFAS No. 146 on January 1, 2003.  Corning has not yet
determined the impact,  if any, that this standard will have on its consolidated
financial position or results of operations.






2.   Business Combinations

On September 30, 2002,  Corning  completed the  acquisition of a 56% interest in
Lucent Technologies  Shanghai Fiber Optic Co., Ltd. and a 68% interest in Lucent
Technologies Beijing Fiber Optic Cable Co., Ltd. from Lucent  Technologies.  The
Shanghai-based  company manufactures optical fiber and the Beijing-based company
manufactures fiber cable.

In connection with an amendment dated September 30, 2002, the consideration paid
to Lucent by Corning was changed from cash to a  combination  of cash and stock.
Corning paid Lucent total  consideration  of $198 million,  comprised of cash of
$123 million,  a note payable of $27 million due in the fourth  quarter of 2002,
and common stock valued at $48 million.  The value of 30 million  common  shares
was determined based on the average market price of Corning's common shares over
the 2-day period before and after the acquisition date. The transaction requires
a further cash payment of $25 million if certain  milestones are achieved in the
fourth quarter.

As Corning holds a controlling interest in both investments, it has consolidated
both entities in its financial  statements.  At September 30, 2002, the entities
had cash of $100 million and a dividend payable to minority  shareholders of $15
million in the fourth quarter.

The  excess  purchase  price over  tangible  net assets  acquired  totaled  $110
million. This entire amount has been recorded as goodwill at September 30, 2002.
As the transaction was completed on September 30, 2002, this purchase allocation
is preliminary.  During the fourth  quarter,  Corning will finalize the purchase
price allocation, which may result in reclassifying a portion of this premium to
intangible   assets.   The  $110   million  of  goodwill  was  assigned  to  the
Telecommunications Segment. The goodwill is not deductible for tax purposes.

The pro forma financial  effect of this  transaction  would not be significantly
different from reported results.

3.   Operating Segments

Corning's reportable operating segments consist of Telecommunications,  Advanced
Materials  and  Information  Display.  Corning  includes  the earnings of equity
affiliates  that are closely  associated  with Corning's  operating  segments in
segment  net  income.  In the  second  quarter  of  2002,  Corning  revised  its
definition of segment net income. Prior to the second quarter, Corning disclosed
restructuring  and  impairment   charges  by  segment  but  excluded  this  from
quantitative  segment  results.  These charges have now been included in segment
net income and  historical  periods have been  conformed  to this  presentation.
Information about the performance of Corning's three operating  segments for the
third quarter and nine months of 2002 and 2001 is presented below. These amounts
exclude revenues,  expenses and equity earnings not specifically identifiable to
segments.






Corning  prepared the financial  results for its three  operating  segments on a
basis that is consistent with the manner in which Corning management  internally
disaggregates  financial  information  to assist in  making  internal  operating
decisions. Corning has allocated some common expenses among segments differently
than it would for stand-alone  financial information prepared in accordance with
GAAP.  These  expenses  include  interest,   taxes,  and  corporate   functions.
Allocation  methodologies  are described in Corning's 2001 Form 10-K/A.  Segment
net income may not be consistent with measures used by other companies.

4.   Restructuring, Impairment and Other Charges

2002 Restructuring Actions
--------------------------

Second Quarter
--------------
During the second quarter,  Corning  undertook  actions to reduce its costs. The
intent to do so was announced in April 2002. At that time, it was estimated that
restructuring,  fixed asset  impairments  and  impairments of investments  could
total approximately $600 million and would be recorded over the second and third
quarters.

Actions approved and initiated in the second quarter include the following:

..    permanent  abandonment  of  certain  construction  projects  that  had been
     stopped   in  2001  in  the   fiber   and   cable   business   within   the
     Telecommunications Segment,
..    closure   of   minor   manufacturing    facilities,    primarily   in   the
     Telecommunications Segment,
..    closure and consolidation of research facilities,
..    elimination  of  positions  worldwide  through  voluntary  and  involuntary
     programs, and
..    divestiture  of a portion of the  controls and  connectors  business in the
     Telecommunications Segment.






In addition,  Corning  impaired  cost based  investments  in a number of private
telecommunications companies.

The charges recorded in the second quarter are summarized in the following table
and described in greater detail below:

Employee related costs                             $   192

                                                   -------
       Total pre-tax charges                           494
Tax benefit                                            166
                                                   -------
       Total after-tax charges                     $   328
                                                   =======

In  addition,  equity  earnings  included  a $14  million  charge  to  impair an
investment in an international cabling venture.

     Restructuring Charges
     ---------------------
     The second  quarter  restructuring  charge of $204  million  included  $192
     million of employee separation costs (including  curtailment losses related
     to pension and  postretirement  health care plans) and $12 million in other
     exit  costs  (principally  lease  termination  and  contract   cancellation
     payments).  The charge  entailed the  elimination  of  approximately  3,600
     hourly  and  salaried  positions  in  the  Telecommunications  Segment  and
     corporate research and administrative staffs organizations.  Employees have
     been informed of the  restructuring  initiatives and benefits  available to
     them under applicable  benefit plans.  These benefits included  involuntary
     separation, early retirement and social programs.

     Impairment of Plant and Equipment
     ---------------------------------
     Corning has evaluated the carrying value of the  long-lived  assets at each
     site impacted by the  restructuring  actions for  impairment.  The carrying
     value of a long-lived  asset is considered  impaired  when the  anticipated
     separately  identifiable  undiscounted  cash flows from that asset are less
     than  the  carrying  value  of  the  asset.  The  impairment  charges  were
     determined  based on the amount by which the  carrying  value  exceeded the
     fair market value of the asset. Corning recorded $224 million in the second
     quarter to impair plant and equipment relating to facilities to be shutdown
     or  disposed,  primarily  in the  fiber and cable  business,  the  photonic
     technologies  business  and  certain  research  facilities.  Of this  total
     charge,  $107 million pertained to abandoned  construction  projects in the
     fiber and cable business, primarily the latest expansion in Concord, NC and
     Oklahoma City, OK.

     A  significant  portion of the assets  impaired was recently  acquired,  or
     built in connection  with capacity  expansions  in  anticipation  of future
     demand.  Most of the impaired  facilities are currently available for sale,
     others will be  demolished  or abandoned.  The impaired  equipment  will be
     auctioned, sold, disposed or abandoned during 2002 and 2003.

     Loss on Divestiture
     -------------------

     In May 2002,  Corning  completed the sale of its appliance  controls  group
     which  was  included  in  the  controls  and  connectors  business  in  the
     Telecommunications  Segment.  In the  second  and  third  quarter  of 2002,
     Corning  received  cash of $24 million and note  proceeds of $6 million and
     recorded  a loss on the sale of  approximately  $16  million  ($10  million
     after-tax).






     Impairment of Cost Investments
     ------------------------------

     In  the  second  quarter,  Corning  recorded  a $60  million  ($37  million
     after-tax)  charge  for other  than  temporary  declines  in  certain  cost
     investments in the Telecommunications  Segment. These investments have been
     written off.

     Third Quarter
     -------------
     The charges  recorded in the third quarter are  summarized in the following
     table and described in greater detail below:

     Employee related costs                                     $    47

     Restructuring Charges
     ---------------------
     The third quarter  restructuring charge of $58 million includes $47 million
     of employee  separation costs (including  special  termination  benefits to
     pension and postretirement health care plans) and $11 million in other exit
     costs (principally lease termination and contract  cancellation  payments).
     The charge entails the elimination of approximately  1,000 positions in the
     Telecommunications Segment and corporate research and administrative staffs
     organizations.   Employees   have  been   informed  of  the   restructuring
     initiatives and benefits  available to them under applicable benefit plans.
     These benefits include involuntary separation,  early retirement and social
     programs.

     Corning  expects the remaining 1,600 employees to be separated by September
     30, 2003.

     Impairment of Plant and Equipment
     ---------------------------------
     Corning  recorded  $67 million to impair  plant and  equipment  relating to
     facilities  to be shutdown or  disposed,  primarily  in the fiber and cable
     business,   the  photonic   technologies   business  and  certain  research
     facilities.

     Fourth Quarter
     --------------
     On October  30,  2002,  Corning  announced  its  intent to take  additional
     measures to attain  profitability in 2003. The continued  decline in demand
     in the  Telecommunications  Segment requires further restructuring to bring
     capacity in line with current  revenues.  The fourth quarter pre-tax charge
     is  expected  to  approximate  $550  million  to $650  million  and  impact
     approximately 2,200 employees.  Approximately one quarter of this charge is
     expected to be paid in cash. The fourth quarter actions will include:






     .    permanent closing of Corning's optical fiber manufacturing facility in
          Noble  Park,  Victoria,  Australia,  and the  proposed  closing of its
          Neustadt Bei Coburg,  Germany plant. These closures are proposed to be
          completed by early 2003.  Corning will also mothball its optical fiber
          manufacturing   facility  in   Concord,   NC  and   transfer   certain
          capabilities to its Wilmington, NC facility. Corning believes that the
          Concord facility can be returned to productive  capacity within six to
          nine months of a decision to reopen,
     .    proposed  reductions in capacity and  employment in Corning's  cabling
          and hardware and equipment locations worldwide to reduce costs, and
     .    permanent  closure  of its  photonic  technologies  thin  film  filter
          manufacturing facility in Marlborough, MA by the end of 2002.

The charge for these actions  includes  exit costs and  impairment of the closed
facilities and severance costs associated with closed and mothballed  locations.
Management is still considering  additional  actions that may be announced later
in  the  fourth  quarter.  It  is  possible  that  additional   impairments  and
restructuring  charges  will result from these  actions or decreases in expected
cash flows from assets not abandoned.

2001 Restructuring Actions
--------------------------

In July and October of 2001, Corning announced a series of restructuring actions
in  response  to  significant  deteriorating  business  conditions  which  began
initially in its Telecommunications  Segment, but eventually spread to its other
businesses  as the year  progressed.  The  following  actions were  approved and
undertaken in 2001:

..    closure of seven major  manufacturing  facilities and the  consolidation of
     several  smaller  facilities,   primarily  in  the  Telecommunications  and
     Advanced Materials Segments,
..    discontinuation  of  its  initiative  in  Corning   Microarray   Technology
     products, part of Corning's life sciences business, and
..    elimination  of  approximately  12,000  positions  affecting  all operating
     segments, but especially impacting the photonic technologies,  hardware and
     equipment and the optical fiber and cable businesses.  This action included
     a selective  voluntary early retirement program for certain employees along
     with involuntary separations.

These actions  resulted in a pre-tax charge  totaling $961 million ($590 million
after-tax  and minority  interest)  for the year ended  December  31, 2001.  The
charge  included  restructuring  costs of $419  million and $542 million for the
impairment of plant and equipment.  Approximately  one third of the total charge
was expected to be paid in cash. As of September 30, 2002,  approximately 11,800
of the 12,000 employees had been separated under the plans.  Corning expects the
remaining  200  employees  to  be  separated  by  December  31,  2002.   Certain
obligations of the plans will be paid in 2003 and beyond.

restructuring reserves as of September 30, 2002:

9.   Pensions

As a result  of  restructuring  activities  undertaken  in the  second  quarter,
Corning  incurred a curtailment  event requiring a remeasurement  of its pension
obligation  at June  30,  2002.  The  provisions  of  SFAS  No.  87,  "Employers
Accounting  for  Pensions"  required  Corning  to record an  additional  minimum
liability  of $180  million  in the  second  quarter  of  2002.  This  liability
represents the amount by which the accumulated  benefit obligation  exceeded the
sum of the fair  market  value of plan  assets and  accrued  amounts  previously
recorded.  The additional  liability may be offset by an intangible asset to the
extent of previously  unrecognized  prior service cost. The intangible  asset of
$81 million at September 30, 2002, is included on the line item entitled  "Other
intangible  assets" in the  Consolidated  Balance Sheet. The remaining amount of
$61 million is recorded as a  component  of  stockholders'  equity and is net of
related tax benefits of $38 million,  on the line item titled "Accumulated other
comprehensive loss" in the Consolidated Balance Sheet at September 30, 2002, and
in "Other comprehensive income (loss)."

10.  Loss Per Common Share

Basic and diluted  loss per common  share is  calculated  by  dividing  net loss
attributable  to common  shareholders  by the weighted  average number of common
shares outstanding during the period.

The potential  common shares  excluded from the  calculation of diluted loss per
share  because  their  effect  would be  anti-dilutive  and the  amount of stock
options  excluded from the  calculation  of diluted loss per share because their
exercise price was greater than the average market price of the common shares of
the periods presented was as follows: (in millions)

11.  Commitments and Contingencies

From time to time, Corning is subject to uncertainties and litigation and is not
always able to predict the outcome of these items with assurance.  Various legal
actions,  claims and proceedings are pending  against  Corning,  including those
arising out of alleged product defects, shareholder matters, product warranties,
patents, asbestos and environmental matters. These issues are discussed fully in
Part II,  Item 1. Legal  Proceedings  of this Form 10-Q.  A  significant  matter
discussed  below involves  Pittsburgh  Corning  Corporation  (PCC), an entity in
which Corning maintains a 50% interest.






Pittsburgh Corning Corporation
------------------------------
Background:
Corning and PPG  Industries,  Inc.  (PPG) each own 50% of the  capital  stock of
Pittsburgh  Corning   Corporation  (PCC).  PCC  and  several  other  defendants,
including PPG and Corning, have been named in numerous lawsuits involving claims
alleging personal injury from exposure to asbestos. On April 16, 2000, PCC filed
for Chapter 11  reorganization  in the United  States  Bankruptcy  Court for the
Western District of Pennsylvania. As of the bankruptcy filing, PCC had in excess
of 140,000 open claims and now has in excess of 240,000 open claims.

Status of Litigation and Current Events:
In the  bankruptcy  court,  PCC in April 2000 obtained a preliminary  injunction
against the  prosecution of asbestos  actions  against its two  shareholders  to
afford  the  parties  a  period  of time  (the  Injunction  Period)  in which to
negotiate a plan of reorganization for PCC.

On May 14, 2002,  PPG announced  that it had agreed with several other  parties,
including certain of its insurance  carriers and  representatives of current and
future asbestos claimants,  on the terms of a settlement arrangement relating to
asbestos claims against PPG and PCC. This settlement  would be incorporated in a
plan of reorganization  for PCC, and would be subject to a favorable vote by 75%
of the asbestos claimants voting on the PCC reorganization plan, and approval by
the  Bankruptcy   Court.   According  to  its   announcement,   PPG  would  make
contributions to a trust under the reorganization plan consisting of:
..    cash payments by PPG's  participating  insurance  carriers of approximately
     $1.7 billion over a 21 year period;
..    the  assignment  of rights to  certain  proceeds  of  policies  by  certain
     insurance carriers not participating in the settlement;
..    PPG's shares in PCC and Pittsburgh Corning Europe, a Belgian corporation;
..    1,388,889 shares of PPG's common stock; and
..    cash payments from PPG of approximately $998 million over 21 years.
PPG announced on July 18, 2002,  that it recorded a charge in its second quarter
results of $495 million after-tax related to this settlement.

The  Injunction  Period as to Corning was extended  through  September 30, 2002,
when it expired by its terms.  Under the terms of the Bankruptcy  Court's Order,
Corning has 90 days from  September  30,  2002,  to seek removal and transfer of
pending  cases in which it is named as a  defendant.  At the time PCC  filed for
bankruptcy  protection,  there were  approximately12,400  claims pending against
Corning  alleging  various  theories  of  liability  based on  exposure to PCC's
asbestos products. Although the outcome of litigation and the bankruptcy case is
uncertain,  management  believes that the separate  corporate status of PCC will
continue to be upheld and that Corning has strong  legal  defenses to any claims
of direct liability arising from PCC's asbestos products.

After PPG announced its settlement,  negotiations between representatives of the
asbestos  claimants and Corning became more intensive.  These  negotiations have
failed to produce a settlement,  but  discussions  continue  intermittently.  In
Corning's  negotiations with the asbestos  claimants,  the range of negotiations
has been framed by demands  translating into  approximately $400 million to $500
million in net present value  (inclusive of insurance),  which is  significantly
lower than that reflected in the PPG settlement.  These  negotiations  have been
difficult,  and no assurances  can be offered that a settlement can be concluded
within this range.

Based on negotiations to date, management believes that a settlement (if one can
be reached) would probably include some  combination of the following  elements:
cash  payments  by Corning  over time into a trust;  contribution  of  Corning's
shares in PCC and Pittsburgh  Corning  Europe and common shares of Corning;  and
insurance  through cash payments or  assignments  of certain rights to insurance
proceeds.  However,  the  structure  of a  settlement  has not been  agreed  and
management can not estimate the likelihood  that any settlement will emerge from
negotiations with the claimants or Corning's  insurers,  or the probability that
Corning will be able to secure a release  through  PCC's plan of  reorganization
upon terms and conditions satisfactory to Corning.






At this time,  it appears more likely than not that  Corning  will  litigate the
asbestos cases, but will continue to explore a settlement through the bankruptcy
process.  The exposure for this asbestos litigation (net of insurance) cannot be
estimated at this time due to the wide range of potential  outcomes.  Corning is
also currently named in approximately 11,400 other cases  (approximately  34,000
claims)  alleging  injuries  from  asbestos.  Those  cases have been  covered by
insurance  without  material impact to Corning to date.  Asbestos  litigation is
inherently difficult, and the outcome of litigation is uncertain.

Accounting and Range of Outcomes
As a result of PCC's bankruptcy filing,  Corning recorded an after-tax charge of
$36 million in the first quarter of 2000 to impair its entire  investment in PCC
and discontinued  recognition of equity earnings. At September 30, 2002, Corning
has not  recorded any  additional  charges  associated  with the outcome of this
litigation.  As noted above, management believes there are strong legal defenses
to the claims against Corning.  Management estimates that the insurance coverage
available to Corning related to these matters exceeds $600 million and depending
on the outcome of potential  coverage  issues may exceed $1 billion.  Management
estimates  that  the  low end of the  range  of loss  resulting  from  continued
litigation is not material.  Due to the inherent uncertainty of asbestos related
litigation,  management  is unable to estimate  the maximum  exposure  from this
litigation.

Alternatively,  in the event that  Corning  and its  insurers  agree to a global
settlement of the  PCC-related  cases through the PCC  bankruptcy  process,  the
outcome may be material  to the  results of  operations  for the period in which
such costs, if any, are recognized. Management expects that any after-tax charge
resulting from Corning's  contributions  as part of a possible  settlement could
approximate  $100  million to $150  million  and will  depend upon the timing of
contributions  and  relative  participation  of insurance  carriers.  Management
cannot provide  assurances  that the ultimate  outcome of a settlement  would be
within this range.

Under either  alternative  management  believes  these  matters will be resolved
without material impact to Corning's overall financial position or its liquidity

12.  7% Series C Mandatory Convertible Preferred Stock  and Series B Convertible
     Preferred Stock

In July and August  2002,  Corning  issued  5.75  million  shares of 7% Series C
mandatory  convertible  preferred stock having a liquidation  preference of $100
per share,  plus accrued and unpaid  dividends,  and  recorded  proceeds of $558
million.  The  mandatory  convertible  stock has an annual  dividend rate of 7%,
payable  quarterly in cash. The first dividend payment date will be November 16,
2002.  The dividends  are also payable  immediately  upon  conversion to Corning
common  stock.  At the time Corning  issued the Series C  convertible  stock,  a
one-time  dividend  was  declared  for all  dividends  that will be payable from
issuance  through the  mandatory  conversion  date of August 16,  2005.  Corning
secured the payment of the dividends  through the issuance of a promissory  note
and used a portion of the proceeds from the sale of the Series C preferred stock
to  purchase  $117  million of U.S.  treasury  securities  that were  pledged as
collateral  to secure the  payments on the  promissory  note.  As a result,  net
proceeds of the offering were $441 million.  In addition,  Corning  redeemed the
remaining  69  thousand  shares of Series B  preferred  stock for $7  million in
August.

The  Series C  preferred  stock  will  automatically  convert  on the  mandatory
conversion  date of August 16,  2005,  into  between  50.813 and 62.5  shares of
Corning common stock,  depending on the then current  market price.  At any time
prior to the mandatory conversion date, holders may elect to convert in whole or
part of their  shares of Series C preferred  stock into 50.813  shares of common
stock plus an amount of cash  equal to the market  value at that time of the pro
rata share of the  collateral  portfolio  that secures the  promissory  note. At
September 30, 2002,  approximately  3.3 million shares of the Series C preferred
stock had been converted into 167.9 million common shares.

As the closing  price of Corning  common stock was $1.60 on July 31,  2002,  the
holder could immediately convert the Series C preferred stock and obtain a value
of  $101.72  (50.813  shares  valued at $1.60 plus  $20.42 in future  dividends)
indicating that the preferred stock contains a beneficial  conversion feature of
$1.72 per preferred share. The beneficial  conversion totaled  approximately $10
million  and  was  charged  to  retained  earnings  in the  third  quarter.  The
beneficial  conversion is also deducted  from  earnings  attributable  to common
shareholders   in  the  third  quarter  and  nine  months   earnings  per  share
calculations of 2002.

Corning applies APB Opinion No. 25,  "Accounting for Stock Issued to Employees,"
for its stock-based  compensation  plans.  Compensation  expense is recorded for
awards of shares or share rights over the period earned. Compensation expense of
$0 million and $2 million was  recorded in the third  quarter and nine months of
2002,  compared  with $1 million and $28 million in the same periods of 2001. If
Corning  had  elected to  recognize  compensation  expense  under SFAS No.  123,
"Accounting for Stock-based Compensation," Corning's net loss, loss attributable
to common shareholders and basic and diluted loss per share in the third quarter
and first nine months of 2002 and 2001 would have been as follows:

                  Financial Condition and Results of Operations
                  ---------------------------------------------

Business
--------

Corning traces its origins to a glass business  established in 1851. The present
corporation was  incorporated in the State of New York in December 1936, and its
name was changed from Corning Glass Works to Corning  Incorporated  on April 28,
1989.

Corning  is a global,  technology-based  corporation,  which  operates  in three
reportable  business  segments:   Telecommunications,   Advanced  Materials  and
Information Display.

The  Telecommunications  Segment  produces  optical  fiber  and  cable,  optical
hardware and equipment,  photonic modules and components and optical  networking
devices for the worldwide  telecommunications industry. Within Corning's optical
fiber and cable business, Corning invented the first low-loss optical fiber more
than 30 years ago and offers a range of optical  fiber  technology  products and
enhancements  for  a  variety  of  applications,   including  premises,  access,
metropolitan,   long-haul   and  submarine   networks.   Corning  --  the  first
manufacturer to introduce laser-optimized fiber(TM) for premises applications --
offers  Infinicor(R)  fibers for local area  networks,  data centers and central
offices.  Corning's SMF-28(R) fiber, the most widely deployed  single-mode fiber
in the world, offers customers an industry-leading package of specifications, as
well as  world-class  reliability,  splicing  and handling  capability.  Corning
SMF-28e(TM)  fiber  enables  additional  transmission  wavelengths  in metro and
access  networks.  LEAF(R)  fiber  enables  greater  capability  for  long-haul,
regional and metropolitan  networks.  Corning's  Vascade(R)  family of submarine
fibers  includes   technologically   advanced  solutions  for  transoceanic  and
short-haul undersea networks.  Corning has two large optical fiber manufacturing
facilities  in North  Carolina,  as well as a  controlling  interest  in  Lucent
Technologies  Shanghai  Fiber Optic Co. Ltd. in China,  purchased from Lucent on
September 30, 2002. On October 30, 2002, Corning announced the permanent closing
of its optical fiber manufacturing facility in Noble Park, Victoria,  Australia,
and the  proposed  closing of its  Neustadt  Bei Coburg,  Germany  plant.  These
closures are proposed to be completed by early 2003.  Corning will also mothball
its optical fiber  manufacturing  facility in Concord,  NC and transfer  certain
capabilities to its Wilmington,  NC facility.  Corning believes that the Concord
facility can be returned to productive  capacity  within six to nine months of a
decision to reopen.

Some of Corning's  optical  fiber  production  is  transferred  to partially and
wholly-owned subsidiaries or equity ventures to be cabled prior to being sold to
end users and the  remaining  fiber  production is sold directly to end users or
third party cablers around the world. Corning's cabling operations include large
facilities in North  Carolina and in Germany and smaller  regional  locations or
equity affiliates.

Corning's hardware and equipment products include cable assemblies,  fiber optic
hardware,  fiber optic  connectors,  optical  components  and  couplers,  splice
equipment, test equipment, accessories, network management solutions and optical
manufacturing services for optical connectivity. For broadband access, Corning's
products include  connection and protection  devices,  digital subscriber lines,
closures,   subscriber  demarcation  points,  outside  plant  enclosures,  metal
enclosures  and  shelters,  plastic  pedestals  and  copper  data  communication
products.  Corning manufacturing  operations for hardware and equipment products
are in North Carolina and Texas, as well as Europe and the Caribbean.

Corning's  photonic  technologies  products  are made  primarily in New York and
Massachusetts.  These  include  erbium  doped fiber  amplifiers  (EDFAs),  Raman
amplifier modules and pumps, and semiconductor optical amplifiers for long-haul,
metro and  access  markets.  Corning's  optical  compensation  products  include
dispersion compensation devices for long-haul and metro networks. Corning offers
a variety of modules and  single-channel  devices for dense wavelength  division
multiplexing  (DWDM)  for  long-haul  and  metro  networks  for high  data  rate
transmissions and signal generation  products,  optical transmission modules and
components  in  optical  system  networks.  Corning's  controls  and  connectors
products  include  coaxial  connectors and associated  assembly tools for use in
cable  television  and broadband  communication  systems,  satellite,  wireless,
telecommunications and military applications. These products are manufactured in
Arizona and Denmark. The  Telecommunications  Segment represented  approximately
48% of total Corning sales during the first nine months of 2002.






The Advanced  Materials Segment  manufactures  specialized  products with unique
properties for customer applications  utilizing glass, glass ceramic and polymer
technologies.  Businesses  within this segment include  environmental  products,
life science products,  semiconductor materials, optical and technical products.
Corning's  environmental  products  manufactured in New York,  Virginia,  China,
Germany  and  South  Africa  include  ceramic  technologies  and  solutions  for
emissions and pollution control in mobile and stationary applications around the
world,  including  automotive  and  diesel  substrate  and filter  products.  As
regulations and laws on emission controls standards have tightened over time and
additional countries have instituted  requirements related to clean air, Corning
continued  to  develop  more  efficient   emission-control  catalytic  converter
substrates with higher density and greater surface area for ultra-low  emissions
vehicles.  Cormetech,  an equity  venture,  manufactures  ceramic  environmental
substrate  products  for  use in  power  plants.  Corning  is  investing  in new
substrate   technologies  for  diesel  emission  control  devices,  with  a  new
production  facility under  construction  in New York to produce diesel products
for Europe, Japan and the United States.

Life sciences  laboratory  products are manufactured in Maine, New York, England
and Mexico, and include microplate  products,  coated slides,  filter plates for
genomics  sample  preparation,  plastic cell culture dishes,  flasks,  cryogenic
vials, roller bottles, mass cell culture products,  liquid handling instruments,
Pyrex(R) glass beakers,  pipettors,  serological pipettes,  centrifuge tubes and
laboratory filtration products. Corning markets these products primarily through
large distributors.

Semiconductor materials manufactured by Corning include high-performance optical
materials,  optical-based  metrology  instruments  and  technical  solutions for
applications in the global semiconductor  industry.  Corning's high purity fused
silica (HPFS(R)) materials  applications include projection and illuminator lens
blanks in  microlithography,  spacecraft  windows and optics used in high-energy
laser  fusion   systems.   Corning's  ultra  low  expansion  glass  is  used  in
manufacturing   integrated  circuits,   mirror  blanks  for  use  in  space  and
ground-based  systems  requiring  high  mobility.  Corning  also makes  fluoride
crystals and  fabricates  optical  components,  including  calcium  fluoride for
customers who make projection and  illuminator  lens systems used in scanner and
stepper systems. Corning's semiconductor materials are manufactured in New York,
Massachusetts and South Carolina.

Other  specialty  materials made by Corning in New York,  Virginia,  England and
France include ophthalmic glass and plastic products,  technical products,  such
as polarizing glass, glass for high temperature  applications,  machinable glass
ceramic for high temperature  applications,  large telescope mirrors and windows
for use in outer space.  Corning's Eurokera equity venture  manufactures  smooth
cooktop   glass/ceramic.   The  Advanced   Materials   Segment   accounted   for
approximately 27% of Corning's sales during the first nine months of 2002.

The  Information  Display  Segment  manufactures  glass  panels and  funnels for
televisions  and cathode ray tubes,  liquid crystal display glass for flat panel
displays and precision lens assemblies for projection video systems.  For use in
notebook computers,  flat panel desktop monitors and other electronic  products,
Corning's  display  technologies  business  manufactures  glass  substrates  for
displays, including Corning 1737 and Eagle 2000(TM) glass substrates.  Corning's
facilities  in  Kentucky,  Japan and Taiwan and its  Samsung  Corning  Precision
equity venture in South Korea develop, manufacture and supply high quality glass
substrates  using a proprietary  fusion forming  technology and know-how to meet
ever-tightening  customer  specifications.  Corning's precision lens business in
Ohio  manufactures  precision  lens  assemblies  for  projection  video  systems
primarily for large consumer electronics  manufacturers.  Corning's conventional
glass television  business includes a 51% partnership  interest in Corning Asahi
Video, a producer of glass panels and funnels for cathode ray  television  tubes
in Pennsylvania and a 50% interest in Samsung Corning Corporation, a producer of
glass  panels and funnels for cathode  ray tubes for  televisions  and  computer
monitors  in Asia  and  Europe.  The  Information  Display  Segment  represented
approximately 24% of Corning's sales during the first nine months of 2002.

Corning and its  subsidiaries  manufacture and process  products at more than 70
plants in 15 countries.

Except as otherwise  indicated by the context,  the terms "Corning" or "Company"
as used herein, mean Corning Incorporated and its consolidated subsidiaries.

Additional  discussion  of Corning  and each of its  segments  is  discussed  in
Management's  Discussion  and Analysis of Financial  Condition  under  Operating
Review and Note 3 (Operating Segments) to the Consolidated Financial Statements.






Competition
-----------

Corning  competes  across  all of its  product  lines with many large and varied
manufacturers,  both domestic and foreign.  Some of these competitors are larger
than Corning, and some have broader product lines.

Competition  within the  telecommunications  industry is intense  among  several
significant  companies.  Corning  represents an important market presence in the
segment's  principal  product  lines.  Price  and new  product  innovations  are
significant  competitive factors. The current downturn in the telecommunications
industry may change the competitive landscape in the future.

In the  Telecommunications  Segment,  the primary competing producers of optical
fiber are Furukawa OFS, Fujikura, Sumitomo, Alcatel, Pirelli and Draka. Furukawa
OFS is Corning's  largest  competitor.  Corning  obtained the first  significant
optical  fiber  patents,  and its large scale  manufacturing  experience,  fiber
process,  technology  leadership  and  intellectual  property  assets yield cost
advantages  relative  to several  of its  competitors.  Corning  is the  largest
producer of optical fiber and cable,  but faces  significant  competition due to
excess capacity in the market place, price pressure and new product innovations.
For optical  fiber  cable,  Corning's  primary  competitors  are OFS,  Furukawa,
Pirelli,  Alcatel,  Alcoa  Fujikura and  Sumitomo.  For hardware and  equipment,
significant  competitors are 3M, Molex, ADC  Communications,  Marconi and Avaya.
For photonic technologies  products,  the largest competitor is JDS Uniphase and
other  competitors  include  Furukawa OFS, Lucent  (Agere),  as well as Marconi,
Siemens, Bosch and Alcatel.  Primary controls and connectors competitors include
PPC, Thomas and Betts, CDI, Andrews Corporation and Rosenberger.

Within  the  Advanced  Materials  Segment,  Corning's  principal  products  face
competition from a variety of materials manufacturers, some of which manufacture
similar products made from materials other than glass and ceramics.  Among other
things, innovation, product quality, performance and service are key competitive
elements.

Within the Advanced  Materials  Segment,  Corning's  environmental  technologies
business faces its principal competition from NGK, Denso and Emitec. The rest of
the  segment  includes a wide range of products  ranging  from glass and plastic
science laboratory products,  semiconductor stepper lenses, to ophthalmic glass,
each of which has a range of competitive  producers.  For  laboratory  products,
Schott Glaswerke,  Kavalier, Kimble and Becton Dickinson & Co. are the principal
worldwide  competitors.  For  Corning's  semiconductor  stepper  lenses,  Schott
Glaswerke is a principal competitor.  For ophthalmic products,  Schott Glaswerke
is the main competitor.

Competition  is also  intense  for  certain  businesses  within the  Information
Display  Segment.  Within  the  Information  Display  Segment,  competition  for
Corning's  liquid  crystal  display  products  comes  from Asahi  Glass,  Nippon
Electric Glass and NH Techno. For conventional television glass, Nippon Electric
Glass, Techneglas, as well as various Asian manufacturers are the competitors.

Corning  strives  to  maintain  its  position  through  technology  and  product
innovation.  For  the  future,  Corning's  competitive  advantage  lies  in  its
commitment  to  research  and  development,  its  financial  resources  and  its
commitment  to  quality.  There is no  assurance  that  Corning  will be able to
maintain its market position or competitive advantage.

Overview

Corning  incurred a net loss in the third  quarter and first nine months of 2002
driven  primarily  by  continued  weak  performance  in  the  Telecommunications
Segment.  Results for the quarter and nine months included charges that resulted
from  restructuring  activities  offset  in part by a gain  on  repurchases  and
retirement  of debt.  These  items are  described  in more  detail in Results of
Operations and Restructuring, Impairment and Other Charges below.

The  negative  trends  beginning  in 2001 such as  softness  in  demand,  excess
manufacturing capacity,  increased intensity of competition and growing pressure
on price and profits have continued to hamper the  telecommunications  market in
2002.  Major  carriers  continue to withhold  capital  spending for a variety of
reasons,  some  of  which  include  network  over-capacity,  bankruptcy  of  key
telecommunications   customers   and   suppliers   and  the   overall   economic
uncertainties in the world economy.  As a result of these uncertainties and lack
of capital spending, Corning has continued to see its revenues and profitability
decline  in  its  Telecommunications   Segment.  Corning  does  not  expect  any
meaningful recovery in the Telecommunications  Segment through at least 2003. As
a result, Corning announced further restructuring initiatives in October 2002 to
help  achieve  profitability  in  2003.  The  total  pre-tax  restructuring  and
impairment  charges for the full year are  currently  expected to range  between
$1.2 billion and $1.3 billion.

Corning has  undertaken  actions to  generate  cash and  strengthen  its balance
sheet. These include:

..    issuance  in July and  August  2002 of 7%  Series C  Mandatory  Convertible
     Preferred Stock generating net cash proceeds of $441 million, and
..    repurchase  and  retirement of debt with an accreted  value of $278 million
     for cash of $183 million for the nine months ended  September  30, 2002. In
     addition,  Corning  has  repurchased  and retired  additional  debt with an
     accreted value of $204 million for $118 million in cash through October 29,
     2002. These  transactions  resulted in pre-tax gains of $90 million through
     September 30, 2002 and $83 million through October 29, 2002.

Results of Operations

Net sales  totaled $837 million for the third quarter of 2002, a decrease of 45%
compared with sales of $1.5 billion in the prior year third  quarter.  Net sales
for the nine months ended September 30, 2002,  were $2.6 billion,  a decrease of
50% compared to the prior year period of $5.3 billion. The sales decline in both
periods was most  pronounced in the  Telecommunications  Segment.  Significantly
lower  demand and price  declines  for  Corning's  fiber and cable and  photonic
technologies products drove a sales decline in that segment of approximately 66%
and 68% for the  quarter  and nine  months of 2002  compared  to the prior  year
periods.

As a percentage of net sales,  third quarter gross margin  decreased to 19% from
34% in the prior year quarter and nine months gross margin decreased to 22% from
35% in the prior  nine-month  period.  Gross margin  continues to be impacted by
lower sales volumes,  particularly in the  Telecommunications  Segment where the
lower volumes are insufficient to cover the fixed manufacturing costs.  Downward
pricing pressure also continues to negatively  impact margins,  primarily in the
optical fiber and cable business.

Selling,  general  and  administrative  (SG&A)  expenses  decreased  41% to $158
million for the third quarter  compared to the prior year quarter,  however SG&A
increased 1 point as a percentage  of net sales to 19%. On a year to date basis,
SG&A declined 33% to $538 million while SG&A  increased 5 points as a percentage
of net sales to 20%.  The  decreases  in expense for the quarter and nine months
reflect  the  impact  of  the  restructuring   actions  and,  for  the  quarter,
approximately  $20 million of favorable  adjustments to compensation and benefit
accruals  and property tax refunds  while the  increases as a percentage  of net
sales  indicate  the decline in revenues  continues  to outpace the cost savings
impact of restructuring actions.






Research,  development and engineering  expenses (RD&E) totaled $115 million and
$375 million for the quarter and nine months which  represented a decline of 25%
and 23%,  respectively,  compared to the prior year periods.  As a percentage of
net sales, RD&E increased 4 points and 5 points for the quarter and nine months,
respectively,  to 14% for both  periods.  The decreases in total expense for the
quarter and nine months  reflect the impact of the  restructuring  actions while
the  increases  as a  percentage  of net sales  indicate the decline in revenues
continues to outpace the cost savings impact of restructuring actions.

Corning's  operating loss as a percentage of net sales deteriorated 10 points to
29% for the third quarter of 2002  compared to the prior year period,  primarily
due to the  deterioration  in  gross  margin,  in  addition  to SG&A and RD&E as
discussed  above.  For the nine  months  ended  September  30,  2002  and  2001,
operating  loss as a percentage of net sales improved 55 points to 37%. The 2001
results were  impacted by a $4.8 billion  charge for the  impairment of goodwill
and intangible assets in the second quarter.

Equity  earnings for the quarter totaled $42 million for an 8% increase over the
same  period in 2001  primarily  due to higher  equity  earnings  in the display
technologies  business. As a percentage of net sales, equity earnings improved 2
points  over the third  quarter of 2001 to 5%. On a year to date  basis,  equity
earnings  were $97 million for an 18% decline over the nine month period of 2001
primarily due to the impairment of an equity investment in the second quarter of
2002. As a percentage of net sales,  equity earnings increased 2 points over the
same period of 2001 to 4% of net sales primarily due to the decline in sales.

Corning's  net loss  totaled  $133  million,  or $0.25 per  share,  in the third
quarter of 2002,  compared to a net loss of $220 million or, $0.24 per share, in
the third quarter of 2001. On a year to date basis,  Corning incurred a net loss
of $593 million,  or $0.74 per share,  compared to a net loss of $4,843 million,
or $5.21 per share,  for the nine months ended  September  30,  2001.  The third
quarter 2001 net loss and diluted loss per share, after adjusting for the impact
of Statement of Financial Accounting Standards (SFAS) No. 142, was $145 million,
or $0.15 per share.  Net loss and diluted loss per share on a year to date basis
for 2001 and adjusted for SFAS No. 142 was $4,529 million, or $4.88 per share.

Corning's  third quarter and year to date results  reflect  significantly  lower
volumes  and  prices  in the  Telecommunications  Segment  compared  to the same
periods for the prior year.  The third  quarter  2002  results  also include net
charges of $125 million ($85 million  after-tax)  resulting  from  restructuring
actions and impairment  charges  undertaken in the third quarter.  These charges
are described in Restructuring,  Impairment and Other Charges. In addition,  the
third quarter results include a gain of $22 million ($13 million  after-tax) due
to repurchases and retirement of a portion of Corning's zero coupon  convertible
debentures.

Corning's  results for the third quarter of 2001 were impacted by  restructuring
actions of $339 million  ($222 million  after-tax)  which  included  charges for
headcount reduction, exit costs and impairment of property, plant and equipment.
The  year to date  loss  for  2001  was  largely  attributable  to a  charge  of
approximately  $4.8 billion  ($4.7 billion  after-tax) in the second  quarter to
impair goodwill and certain other intangible assets of the photonic technologies
business. Restructuring charges through nine months of 2001 totaled $347 million
($227 million after-tax).  In addition,  year to date results were also affected
by a charge of $273 million  ($184 million  after-tax) in the second  quarter to
write-down excess and obsolete inventory in the photonic technologies business.

Net loss as a percentage of net sales  deteriorated 1 point to 16% for the third
quarter of 2002 compared to the same period in 2001. The deterioration reflected
in  gross  margin  and  operating  loss was  partially  offset  by the  gains on
repurchases  of  debt  and  increased  income  tax  benefits  for  the  quarter.
Comparisons  of a percentage on a year to date basis are not  meaningful  due to
the very large after-tax second quarter 2001 impairment charge of $4.7 billion.






Restructuring, Impairment and Other Charges

2002 Restructuring Actions
--------------------------

Second Quarter
--------------
During the second quarter,  Corning  undertook  actions to reduce its costs. The
intent to do so was announced in April 2002. At that time, it was estimated that
restructuring,  fixed asset  impairments  and  impairments of investments  could
total approximately $600 million and would be recorded over the second and third
quarters.

Actions approved and initiated in the second quarter include the following:

..    permanent  abandonment  of  certain  construction  projects  that  had been
     stopped   in  2001  in  the   fiber   and   cable   business   within   the
     Telecommunications Segment,
..    closure   of   minor   manufacturing    facilities,    primarily   in   the
     Telecommunications Segment,
..    closure and consolidation of research facilities,
..    elimination  of  positions  worldwide  through  voluntary  and  involuntary
     programs, and
..    divestiture  of a portion of the  controls and  connectors  business in the
     Telecommunications Segment.

In addition,  Corning  impaired  cost based  investments  in a number of private
telecommunications companies.

The charges recorded in the second quarter are summarized in the following table
and described in greater detail below:

Employee related costs                                  $   192

       Total after-tax charges                          $   328
                                                        =======

In  addition,  equity  earnings  included  a $14  million  charge  to  impair an
investment in an international cabling venture.

     Restructuring Charges
     ---------------------
     The second  quarter  restructuring  charge of $204  million  included  $192
     million of employee separation costs (including  curtailment losses related
     to pension and  postretirement  health care plans) and $12 million in other
     exit  costs  (principally  lease  termination  and  contract   cancellation
     payments).  The charge  entailed the  elimination  of  approximately  3,600
     hourly  and  salaried  positions  in  the  Telecommunications  Segment  and
     corporate research and administrative staffs organizations.  Employees have
     been informed of the  restructuring  initiatives and benefits  available to
     them under applicable  benefit plans.  These benefits included  involuntary
     separation, early retirement and social programs.






     Impairment of Plant and Equipment
     ---------------------------------
     Corning has evaluated the carrying value of the  long-lived  assets at each
     site impacted by the  restructuring  actions for  impairment.  The carrying
     value of a long-lived  asset is considered  impaired  when the  anticipated
     separately  identifiable  undiscounted  cash flows from that asset are less
     than  the  carrying  value  of  the  asset.  The  impairment  charges  were
     determined  based on the amount by which the  carrying  value  exceeded the
     fair market value of the asset. Corning recorded $224 million in the second
     quarter to impair plant and equipment relating to facilities to be shutdown
     or  disposed,  primarily  in the  fiber and cable  business,  the  photonic
     technologies  business  and  certain  research  facilities.  Of this  total
     charge,  $107 million pertained to abandoned  construction  projects in the
     fiber and cable business, primarily the latest expansion in Concord, NC and
     Oklahoma City, OK.

     A  significant  portion of the assets  impaired was recently  acquired,  or
     built in connection  with capacity  expansions  in  anticipation  of future
     demand.  Most of the impaired  facilities are currently available for sale,
     others will be  demolished  or abandoned.  The impaired  equipment  will be
     auctioned, sold, disposed or abandoned during 2002 and 2003.

     Loss on Divestiture
     -------------------

     In May 2002,  Corning  completed the sale of its appliance  controls  group
     which  was  included  in  the  controls  and  connectors  business  in  the
     Telecommunications  Segment.  In the  second  and  third  quarter  of 2002,
     Corning  received  cash of $24 million and note  proceeds of $6 million and
     recorded  a loss on the sale of  approximately  $16  million  ($10  million
     after-tax).

     Impairment of Cost Investments
     ------------------------------

     In  the  second  quarter,  Corning  recorded  a $60  million  ($37  million
     after-tax)  charge  for other  than  temporary  declines  in  certain  cost
     investments in the Telecommunications  Segment. These investments have been
     written off.

     Third Quarter
     -------------
     The charges  recorded in the third quarter are  summarized in the following
     table and described in greater detail below:

     Employee related costs                                     $    47

     Restructuring Charges
     ---------------------
     The third quarter  restructuring charge of $58 million includes $47 million
     of  employee  separation  costs  (including  special  termination  benefits
     related to pension and postretirement health care plans) and $11 million in
     other exit costs (principally  lease termination and contract  cancellation
     payments).  The charge  entails  the  elimination  of  approximately  1,000
     positions  in the  Telecommunications  Segment and  corporate  research and
     administrative  staffs  organizations.  Employees have been informed of the
     restructuring  initiatives and benefits  available to them under applicable
     benefit  plans.  These  benefits  include  involuntary  separation,   early
     retirement and social programs.

     Corning  expects the remaining 1,600 employees to be separated by September
     30, 2003.

     Impairment of Plant and Equipment
     ---------------------------------
     Corning  recorded  $67 million to impair  plant and  equipment  relating to
     facilities  to be shutdown or  disposed,  primarily  in the fiber and cable
     business,   the  photonic   technologies   business  and  certain  research
     facilities.

Cost Savings
------------

Corning expects to realize annualized savings of approximately $265 million as a
result of the second and third quarter 2002 restructuring  actions.  The savings
consist of lower wage and benefit costs, avoided depreciation and fixed costs on
closed facilities.

Although  certain of the cost reduction  programs will positively  impact second
half results, management does not expect to realize all of the savings until the
beginning  of 2003.  Approximately  40% of the  savings  from the  restructuring
actions  will be  realized  in cost of sales with the  remainder  split  between
selling,  general and administrative  and research,  development and engineering
expenses.

Fourth Quarter
--------------
On October 30, 2002, Corning announced its intent to take additional measures to
attain   profitability  in  2003.  The  continued   decline  in  demand  in  the
Telecommunications  Segment requires further  restructuring to bring capacity in
line with current  revenues.  The fourth  quarter  pre-tax charge is expected to
approximate  $550  million  to  $650  million  and  impact  approximately  2,200
employees.  Corning expects to realize  annualized cost savings of approximately
$165  million  as a result of the  fourth  quarter  actions.  Approximately  one
quarter  of this  charge is  expected  to be paid in cash.  The  fourth  quarter
actions will include:

..    permanent  closing of Corning's  optical  fiber  manufacturing  facility in
     Noble Park, Victoria,  Australia,  and the proposed closing of its Neustadt
     Bei Coburg,  Germany plant.  These closures are proposed to be completed by
     early 2003.  Corning  will also  mothball its optical  fiber  manufacturing
     facility  in  Concord,   NC  and  transfer  certain   capabilities  to  its
     Wilmington, NC facility.  Corning believes that the Concord facility can be
     returned to productive  capacity within six to nine months of a decision to
     reopen,
..    proposed  reductions in capacity and  employment  in Corning's  cabling and
     hardware and equipment locations worldwide to reduce costs, and
..    permanent   closure  of  its   photonic   technologies   thin  film  filter
     manufacturing facility in Marlborough, MA by the end of 2002.

The charge for these actions  includes  exit costs and  impairment of the closed
facilities and severance costs associated with closed and mothballed  locations.
Management is still considering  additional  actions that may be announced later
in  the  fourth  quarter.  It  is  possible  that  additional   impairments  and
restructuring  charges  will result from these  actions or decreases in expected
cash flows from assets not abandoned.






2001 Restructuring Actions
--------------------------

In July and October of 2001, Corning announced a series of restructuring actions
in  response  to  significant  deteriorating  business  conditions  which  began
initially in its Telecommunications  Segment, but eventually spread to its other
businesses  as the year  progressed.  The  following  actions were  approved and
undertaken in 2001:

..    closure of seven major  manufacturing  facilities and the  consolidation of
     several  smaller  facilities,   primarily  in  the  Telecommunications  and
     Advanced Materials Segments,
..    discontinuation  of  its  initiative  in  Corning   Microarray   Technology
     products, part of Corning's life sciences business, and
..    elimination  of  approximately  12,000  positions  affecting  all operating
     segments, but especially impacting the photonic technologies,  hardware and
     equipment and the optical fiber and cable businesses.  This action included
     a selective  voluntary early retirement program for certain employees along
     with involuntary separations.

These actions  resulted in a pre-tax charge  totaling $961 million ($590 million
after-tax  and minority  interest)  for the year ended  December  31, 2001.  The
charge  included  restructuring  costs of $419  million and $542 million for the
impairment of plant and equipment.  Approximately  one third of the total charge
was expected to be paid in cash. As of September 30, 2002,  approximately 11,800
of the 12,000 employees had been separated under the plans.  Corning expects the
remaining  200  employees  to  be  separated  by  December  31,  2002.   Certain
obligations of the plans will be paid in 2003 and beyond.

The  following  table  illustrates  the  charges,  credits  and  balances of the
restructuring reserves as of September 30, 2002:

Goodwill and Other Intangible Assets

In June 2001, the Financial  Accounting  Standards  Board (FASB) issued SFAS No.
142, "Goodwill and Other Intangible Assets." Among other provisions, goodwill is
no longer  amortized  but is  subject  to  impairment  tests at least  annually.
Corning adopted SFAS No. 142 on January 1, 2002.  Corning  completed its initial
impairment  review  during  the  first  quarter  and  concluded  a  transitional
impairment charge from the adoption of the standard was not required.






Corning has selected the fourth quarter to conduct annual  impairment tests. The
outcome of the impairment test is primarily dependent upon the fair value of the
reporting units.  Business  conditions in the  telecommunications  industry have
deteriorated  during the year and are  depressed  such that it appears  the fair
value of Corning's  telecommunications reporting unit is currently lower than at
the benchmark  assessment date of January 2002. As part of the annual impairment
test, management is currently studying short and long-term market indicators and
alternative  growth  patterns.  Based on the work  performed to date, it appears
reasonably  possible that a portion,  but not all of the  company's  goodwill is
impaired. Management will complete the impairment test in the fourth quarter and
record any required  goodwill  impairment  charge.  The goodwill  related to the
Telecommunications  Segment is $1.9  billion at September  30, 2002.  Management
believes  there are a range of possible  outcomes and no assurance  can be given
that an  impairment  charge  will not be  required.  A charge  would  lower  the
company's  equity and could  reduce  availability  under the unused $2.0 billion
revolving  credit  facility.  See  Liquidity  and Capital  Resources for further
information.

Outlook

Business conditions in the  Telecommunications  Segment have been very difficult
due  to  sharply  reduced  capital  spending  by  telecommunications  companies.
Management expects that these difficult conditions may continue through at least
the end of 2003. While management ultimately expects a recovery, it is difficult
to forecast when capital  spending by Corning's  customers will return to normal
levels and therefore  difficult to forecast future revenues and earnings in this
segment in the short term.

Corning  expects  fourth quarter net sales to be in the range of $775 million to
$825 million and also anticipates a loss in a range of $0.08 to $0.12 per share,
excluding restructuring and impairment charges.  Continued pricing pressure will
impact revenues and sales in the  telecommunications  businesses are expected to
remain at  depressed  levels.  Corning  anticipates  revenues  from its Advanced
Materials  and  Information  Display  Segments  to remain  strong in the  fourth
quarter led by its liquid crystal display  business,  which continues to operate
at full capacity.

Management  continues to believe Corning has ample liquidity to meet its funding
needs for the foreseeable  future.  Corning finished the third quarter with $1.6
billion  in cash and  short-term  investments  and an  unused  revolving  credit
facility of $2.0 billion.  Capital  spending for 2002 is expected to approximate
$400 million.

Operating Segments

Corning's reportable operating segments consist of: Telecommunications, Advanced
Materials  and  Information  Display.  Corning  includes  the earnings of equity
affiliates  that are closely  associated  with Corning's  operating  segments in
segment  net  income.  In the  second  quarter  of  2002,  Corning  revised  its
definition of segment net income. Prior to the second quarter, Corning disclosed
restructuring  and  impairment   charges  by  segment  but  excluded  this  from
quantitative  segment  results.  These  charges  have now been  included  in the
segment  net  income  and  historical   periods  have  been  conformed  to  this
presentation.  Information  about the  performance of Corning's  three operating
segments  for the third  quarter and nine  months of 2002 and 2001 is  presented
below.  These  amounts  exclude  revenues,  expenses  and  equity  earnings  not
specifically identifiable to segments.

Corning  prepared the financial  results for its three  operating  segments on a
basis that is consistent with the manner in which Corning management  internally
disaggregates  financial  information  to assist in  making  internal  operating
decisions. Corning has allocated some common expenses among segments differently
than it would for stand-alone  financial information prepared in accordance with
GAAP.  These  expenses  include  interest,   taxes,  and  corporate   functions.
Allocation  methodologies  are described in Corning's 2001 Form 10-K/A.  Segment
net income may not be consistent with measures used by other companies.

The  Telecommunications  Segment  produces  optical  fiber  and  cable,  optical

telecommunications  industry. Sales of each business in the segment are provided
in the table above.

Segment Restructuring Actions and Impairment Charges
----------------------------------------------------
This segment incurred  significant  restructuring and impairment charges in both
years.  The second and third  quarter  2002  charges are  described in detail in
Restructuring,  Impairment and Other Charges.  The activities were undertaken to
reduce the operating  cost  structure as a result of continued  lower  revenues.
Approximately  half of the 2002 charge is impairment of fixed assets,  primarily
in the fiber and cable business.  The majority of the asset  impairments in this
business represent the permanent  abandonment of certain  construction  projects
that had been stopped in 2001 in the fiber and cable  business.  The rest of the
charge  represents  impairments  of cost  based  investments,  primarily  in the
photonic  technologies  business,  and  severance  and benefits for retirees and
separated personnel in all businesses.  The restructuring  actions announced for
the fourth quarter will impact all of the businesses within this segment.

The impairment charge incurred in the second quarter of 2001 relates to goodwill
and  certain  acquired  intangible  assets  from  acquisitions  in the  photonic
technologies business.

Segment Overview
----------------
As the restructuring and impairment charges are described above, the performance
discussion below addresses losses and earnings before restructuring,  impairment
and other charges.

Sales in the segment declined 66% and 68% from the third quarter and nine months
of 2001, respectively, as each business in the segment experienced a significant
decline in volume.  The segment incurred losses of $137 million and $421 million
before restructuring, impairment and other charges in the third quarter and nine
months of 2002,  compared to income of $18 million and $199 million in the prior
year periods,  primarily due to the significant  decrease in sales volume.  Each
business also reported a loss in 2002 for the third quarter and nine months. The
declines from 2001 are caused by significantly reduced volumes in all businesses
as a result of the lack of capital spending in the telecommunications industry.






Optical Fiber and Cable
-----------------------
The optical  fiber and cable  business is the largest  business in the  segment.
Sales in the optical fiber and cable business  declined 75% for both the quarter
and nine months ended  September  30, 2002,  compared to the prior year periods.
The decrease  was  primarily  due to a sales volume  decline for fiber and cable
products of more than 60% for the  quarter  and nine months over the  comparable
prior year periods as well as double digit price declines.

The  optical  fiber and cable  business  incurred a loss  before  restructuring,
impairment  and other  charges  for both the  quarter  and nine  months of 2002,
compared to profits in the prior year periods due to  significantly  lower sales
volume, declining prices and unfavorable product mix.

As discussed  earlier in the MD&A,  this  business  will  undertake  significant
restructuring  actions in the fourth quarter. The actions will include permanent
closure  of  two  smaller  international  fiber  manufacturing  plants  and  the
mothballing  of the Concord  facility.  In  addition,  cabling  operations  will
continue  to be  consolidated.  Corning is not  exiting  any product or business
lines as a result of the decision to reduce  capacity but is adjusting  capacity
to  most  efficiently  meet  expected  demand  levels  through  at  least  2003.
Management  believes  that the Concord  facility  can be returned to  productive
capacity  within six to nine months of a decision to do so and  construction  in
progress  at the  Concord  facility  can be  completed  efficiently.  Management
believes the Concord and Wilmington plants will provide sufficient  capacity for
the foreseeable future of this business.

Hardware and Equipment
----------------------
Sales in the hardware and equipment business decreased 27% and 36% for the three
and nine months ended September 30, 2002,  compared to the same periods of 2001.
The sales decreases were primarily due to the overall lack of spending impacting
the entire  telecommunications  industry.  The loss for the quarter doubled over
the loss incurred in the third quarter of 2001, primarily due to the decrease in
sales  volume.  The year to date loss was also driven by lower volumes and price
pressure compared to earnings in 2001.

This business will undertake  restructuring actions in the fourth quarter. These
actions  are  expected  to include  exiting  certain  product  lines,  headcount
reductions and asset impairments.

Photonic Technologies
---------------------
Sales in the photonic  technologies  business declined 78% and 81% for the three
and nine months ended September 30, 2002, primarily due to lower sales volume as
network buildouts in the telecommunications  industry have declined resulting in
much lower demand for photonic  products.  The business  incurred a loss for the
quarter  and nine months of 2002,  primarily  due to  significantly  lower sales
volumes.  However,  the 2002  losses  improved  over the losses  incurred in the
comparable  periods  of  2001,  primarily  due  to  the  significant   inventory
write-down in the second  quarter of 2001. The results in 2002 also reflect cost
reductions resulting from restructuring actions taken in 2001 and early 2002.

The 2001  year to date  results  for  this  business  include  a  write-down  of
inventory  of $274  million.  During the second  quarter of 2002,  the  business
favorably  resolved  an open issue  from the third  quarter of 2001 with a major
customer,  resulting  in the  recognition  of revenue of $14 million and pre-tax
income of $3  million.  This  revenue  was  recognized  in part on  shipment  of
inventory previously reserved. In addition,  the business settled an open matter
with a significant  vendor  resulting in the reversal of a vendor reserve of $20
million that was recorded in the third quarter of 2001. In total,  the impact of
these  settlements in the second quarter was income of $23 million pre-tax.  The
business  also  recorded  inventory  write-downs  of $20 million  pre-tax in the
second quarter of 2002.

The  photonic  technologies  business  operates in a severely  depressed  market
environment.  In the third quarter, certain competitors indicated they will exit
the  business and others  announced  decisions to  consolidate  or  restructure.
Industry consolidation could impact Corning's sales adversely in the short term.
Management is evaluating the  consequences  of these industry events on the long
term  positioning  of this  business in the  marketplace  and is  continuing  to
evaluate alternative strategic decisions for the photonic technologies business.
While certain product lines are promising in the event of industry recovery, the
pace of that recovery is uncertain. Some of the alternatives under consideration
may entail  significant  restructuring  charges or  write-downs  in  tangible or
intangible  assets.  Long-lived  assets of this business  adjusted for announced
fourth quarter impairments approximate $400 million at September 30, 2002.






Controls and Connectors
-----------------------
Sales in the  controls and  connectors  business  decreased  62% and 45% for the
three and nine months ended September 30, 2002, due to the sale of the appliance
controls   group  in  May  2002  and  the  lack  of  capital   spending  in  the
telecommunications  industry.  Earnings  were also  down due to the lower  sales
volumes as the business  incurred losses for the quarter and nine months of 2002
compared to earnings in both  periods in 2001.  The loss on  divestiture  of $16
million ($10 million  after-tax) is included in  restructuring,  impairment  and
other  charges.  Restructuring  actions  to be taken in the fourth  quarter  are
intended to reduce operating costs within this business.

The Advanced  Materials Segment  manufactures  specialized  products with unique
applications  utilizing  glass,  glass  ceramic  and polymer  technologies.  The
largest  businesses  in this  segment are  environmental  technologies  and life
sciences. Sales of these businesses are provided in the table above.

The  restructuring  costs recorded in 2002 in this segment  consist  entirely of
severance and benefits for retired and separated employees across all businesses
in the segment.  The  performance  discussion  below compares  segment  earnings
before restructuring charges.

Sales in the  Advanced  Materials  Segment  in the  third  quarter  of 2002 were
relatively  flat compared to the third quarter of 2001, as decreased  demand for
semiconductor  materials  and the  exit  of  lighting  products  was  offset  by
increased sales in environmental  technologies and life sciences. Sales declined
7% for the nine months  ended  September  30,  2002,  compared to the prior year
period as the  demand  for  semiconductor  materials  fell  sharply in the first
quarter.  Segment  earnings before  restructuring  charges  increased 63% in the
third  quarter of 2002  compared  to the prior  year  quarter  primarily  due to
improved  performance in life sciences and environmental  technologies.  Segment
earnings  before  restructuring  charges  declined 26% for the nine months ended
September  30, 2002,  compared to the prior year period,  as improved  operating
performance in the life sciences  business and stronger equity earnings was more
than  offset  by  decreased  earnings  in  the  environmental  technologies  and
semiconductor materials businesses.






Sales in the  environmental  technologies  business  increased 13% for the third
quarter of 2002,  compared to 2001  primarily  due to higher sales  volume.  The
sales growth was driven by increased auto production due to financing incentives
by  automobile  manufacturers.  Sales  for the  first  nine  months of 2002 were
relatively  flat  compared to the prior year period as higher  sales  volume was
offset by downward pricing  pressure.  Earnings in this business  increased over
50% for the third  quarter,  primarily due to higher equity  earnings.  Earnings
decreased over 10% for the nine months ended September 30, 2002, as the increase
in  equity   earnings  was  offset  by  price  declines  as  well  as  increased
manufacturing and development costs related to new products.

Sales in the life  sciences  business  increased 9% and 5% for the third quarter
and nine  months of 2002,  compared  to the same  periods  of 2001 due to strong
growth in all product  lines.  Earnings in the business for both the quarter and
nine  months of 2002 more than  doubled  over the  comparable  periods  of 2001,
primarily due to cost savings  resulting from the  discontinuation  of Corning's
investment  in  microarray  technology  products  in the third  quarter of 2001,
improved manufacturing efficiencies and higher sales.

Sales in Corning's  other Advanced  Materials  businesses  decreased 16% and 25%
from the third quarter and nine months of 2001,  respectively.  These  decreases
were led by lower  sales  volume of high  purity  fused  silica  products in the
semiconductor  materials  business  as  capital  spending  in the  semiconductor
equipment  industry  continues to be down. The loss for the quarter doubled over
the loss  incurred  in the prior year  quarter  while the  business  went from a
modest  profit for the nine months of 2001 to a loss in the same period of 2002.
The losses are due to significantly lower sales volume and increased spending in
development and engineering for calcium fluoride products.

The  Information  Display  Segment  manufactures  glass  panels and  funnels for
televisions and CRTs  (conventional  video  components),  liquid crystal display
glass  for  flat  panel  display  (display   technologies)  and  precision  lens
assemblies for projection video systems.






Sales in the  Information  Display  Segment  increased  25% and 5% in the  third
quarter  and nine  months  of 2002,  respectively,  compared  to the  comparable
periods of 2001.  Strong growth in the display  technologies  and precision lens
businesses  drove the quarter  increase while on a year to date basis the strong
growth in both  businesses  was partially  offset by extremely weak sales in the
conventional video components business.  Segment net income in the third quarter
increased  38%  compared  to the same  period in 2001  primarily  due to display
technologies  and precision  lens while segment net income  remained  relatively
flat for nine months of 2002,  compared to the prior year as significantly lower
earnings  at   conventional   video   components   were  offset  by  performance
improvements in the display technologies and precision lens businesses.

Sales in the display  technologies  business  increased 34% and 32% in the third
quarter and nine months of 2002 compared to 2001, due to higher sales volume, as
penetration in the desktop market  increased,  and less pressure on the yen. The
prior year's nine month sales were unusually weak due to an inventory correction
in the industry in the first  quarter of 2001.  Volume gains of over 50% for the
quarter  and nine months of 2002 were  partially  offset by price  declines  and
foreign currency  exposure to the yen.  Earnings in the business  increased over
30% for the quarter and nine months compared to the prior year periods primarily
due to volume gains and improved equity earnings from Samsung Corning Precision,
a Korean manufacturer of liquid crystal display glass. This business is expected
to continue its growth.  Both Corning and Samsung  Corning  Precision  Glass Co.
have recently approved expansions of manufacturing capacity in Taiwan and Korea,
respectively.  These  capital  projects  are  expected to begin with  production
anticipated to start in 2003.

Sales in the precision lens business  increased 32% and 21% in the third quarter
and nine  months of 2002  compared  to the prior  year  periods,  as a result of
continued strong volume growth for digital projection televisions,  particularly
in North America and Asia,  driven by demand for larger size  televisions in the
entertainment market sector.  Earnings in this business for the third quarter of
2002  increased  more than 50% over the prior year  period  due to sales  volume
gains.  Earnings for the nine months ended  September 30, 2002,  increased  more
than 30% over the prior year period as sales volume gains were partially  offset
by price declines.

Sales in the  conventional  video  components  business  were  flat in the third
quarter of 2002  compared to 2001 while sales  declined 36% over the nine months
of 2002  compared  to 2001.  Pricing  pressure  is strong in this  market due to
increased  competition.  A significant  portion of this business is concentrated
with few customers,  two of which have recently merged. One significant customer
has exited the business and sales demand from another key customer is uncertain.
Management is  considering  operational  and strategic  alternatives  should the
business  continue to decline.  The loss in the base business  increased for the
third  quarter and nine months,  compared to 2001 due to decreased  sales volume
and a continued increase in competitive pricing pressure.  Corning's  investment
in the long-lived assets of this business totaled  approximately $115 million at
September 30, 2002.  Samsung Corning,  a 50% owned  manufacturer of glass panels
and funnels based in South Korea, also experienced pricing pressure resulting in
a decline  in equity  earnings  for the third  quarter  and nine  months of 2002
compared to the prior year periods.

The totals of Corning's operating segments were as follows:



                                                                    Three months ended              Nine months ended

Income Taxes

Corning's effective income tax benefit rate for the three and nine month periods
ended  September  30, 2002,  was 30.3% and 29.7%,  respectively.  The income tax
benefit  rate in the  third  quarter  and nine  months of 2002 was  impacted  by
specific  tax  benefit  calculations  for  restructuring,  impairment  and other
charges and the gain on repurchases of debt. The effective  benefit rate without
consideration  of these items was 31.1% and 27%,  respectively,  for the quarter
and nine months of 2002.  The  effective  income tax benefit rate in the quarter
and year to date is lower than the U.S.  statutory income tax rate of 35% due to
the impact of unusable tax credits and nondeductible expenses and losses.

In 2002, the U.S.  enacted tax legislation  that extended the net operating loss
carryback period from two to five years. Due to this legislation change, Corning
will be able to carryback the anticipated  2002 U.S.  federal net operating loss
and claim a refund which would not have otherwise been available. Current assets
at  September  30,  2002,  include a  receivable  of $185 million as a result of
Corning  availing  itself of this  opportunity.  Corning expects to receive this
refund in the second quarter of 2003.

The  effective  income  tax  benefit  rate for the three and nine  months  ended
September 30, 2001, was 18.8% and 0.6%.  These tax rates are much lower than the
U.S. statutory income tax rate, primarily due to non-tax deductible amortization
of acquired intangibles and goodwill.






Liquidity and Capital Resources

At  September  30,  2002,  Corning  had  $1.6  billion  in cash  and  short-term
investments and an unused  revolving  credit facility of $2.0 billion.  Cash and
cash equivalents  decreased $54 million from December 31, 2001, while short-term
investments decreased $564 million for the same period. Significant uses of cash
and short-term  investments in 2002 include $654 million of net debt  repayments
and $193 million of restructuring payments. Cash and short-term investments were
essentially  flat  compared to September 30, 2001, as the proceeds from issuance
of 3.5% convertible debt in November 2001 and 7% Series C mandatory  convertible
preferred  stock in August  2002 (as  discussed  below)  were offset by the debt
repayments and restructuring payments.

During the first nine months of 2002,  Corning  made  payments  of $177  million
related to  employee  costs and $16  million in other exit costs  related to the
restructuring  actions.  Corning expects additional payments to approximate $143
million  in the  fourth  quarter  and  $350  million  in 2003.  Corning  expects
approximately one-third of the 2002 restructuring charges to be paid in cash.

In July and August  2002,  Corning  issued  5.75  million  shares of 7% Series C
mandatory  convertible  preferred stock having a liquidation  preference of $100
per share,  plus  accrued and unpaid  dividends,  resulting  in proceeds of $558
million.  The  mandatory  convertible  stock has an annual  dividend rate of 7%,
payable  quarterly in cash. The first dividend payment date will be November 16,
2002.  The dividends  are also payable  immediately  upon  conversion to Corning
common  stock.  At the time Corning  issued the Series C  convertible  stock,  a
one-time  dividend  was  declared  for all  dividends  that will be payable from
issuance  through the  mandatory  conversion  date of August 16,  2005.  Corning
secured the payment of the dividends  through the issuance of a promissory  note
and used a portion of the proceeds from the sale of the Series C preferred stock
to  purchase  $117  million  of U.S.  treasury  securities  that was  pledged as
collateral  to  secure  the  payments  on the  promissory  note  evidencing  its
obligation  to pay  dividends  resulting  in net  proceeds of $441  million.  In
addition,  Corning  redeemed  the  remaining  69  thousand  shares  of  Series B
preferred stock for $7 million in August.

The  Series C  preferred  stock  will  automatically  convert  on the  mandatory
conversion  date of August 16,  2005,  into  between  50.813 and 62.5  shares of
Corning common stock,  depending on the then current  market price.  At any time
prior to the mandatory conversion date, holders may elect to convert in whole or
part of their  shares of Series C preferred  stock into 50.813  shares of common
stock plus an amount of cash  equal to the market  value at that time of the pro
rata share of the  collateral  portfolio  that secures the  promissory  note. At
September 30, 2002,  approximately  3.3 million shares of the Series C preferred
stock had been converted into 167.9 million common shares.

As the closing  price of Corning  common stock was $1.60 on July 31,  2002,  the
holder could immediately convert the Series C preferred stock and obtain a value
of  $101.72  (50.813  shares  valued at $1.60 plus  $20.42 in future  dividends)
indicating that the preferred stock contains a beneficial  conversion feature of
$1.72 per preferred share. The beneficial  conversion totaled  approximately $10
million  and  was  charged  to  retained  earnings  in the  third  quarter.  The
beneficial  conversion is also deducted  from  earnings  attributable  to common
shareholders   in  the  third  quarter  and  nine  months   earnings  per  share
calculations of 2002.

Cash requirements for working capital,  research and development,  acquisitions,
capital  expenditures,   debt  repayments,  and  restructuring  liabilities  are
expected to be funded from cash,  short-term  investments  on hand and  business
dispositions.

Cash Flows

For the nine months ended  September 30, 2002,  cash used in operations was $149
million,  primarily  due to reduced  sales,  lower  accounts  payable  and other
current liabilities and $193 million of cash payments for restructuring charges.
Operations  provided  cash of $1,224  million in the first  nine  months of 2001
after adjustment for non cash items primarily due to  restructuring,  impairment
and other  charges.  The adverse  trend is primarily due to the sharp decline in
revenues in the Telecommunications Segment.






Cash provided by investing  activities  was $219 million  through  September 30,
2002,  reflecting net cash of $566 million from  short-term  investments and $30
million from the sale of the appliance  controls group partially  offset by $283
million of capital  expenditures and $56 million of acquisitions.  This compares
to a use of cash  totaling  $1,954  million  in the same  period  of  2001.  The
variance between years is primarily due to significantly  lower capital spending
which was reduced 82% from 2001.

Cash used in  financing  activities  for the first nine  months of 2002 was $147
million and  reflected  $558 million in proceeds  from the issuance of preferred
stock offset by a $475 million  reduction of short-term debt, which included the
repayment of all commercial  paper. In addition,  $183 million was used for open
market  repurchases of a portion of the zero coupon  convertible  debentures and
$67  million  was used for  preferred  stock  dividends.  This  compares to cash
provided by financing activities of $222 million in 2001 which included proceeds
of $225  million  from a common  stock  offering  in  August  2001 and  dividend
payments of $112 million to common shareholders.

As of September 30, 2002, Corning  repurchased and retired a portion of its zero
coupon  convertible  debentures due November 8, 2015,  with an accreted value of
$278  million in  exchange  for cash of $183  million in a series of open market
purchases. Corning recorded a pre-tax gain of $90 million on these transactions,
net of the write-off of the  unamortized  issuance costs.  Corning  recorded the
gain on  repurchases  as a component of income from  continuing  operations,  as
permitted by SFAS No. 145. The debentures may be put back to Corning on November
8, 2005,  at $819.54  per  debenture  and on  November  8, 2010,  at $905.29 per
debenture.  Corning has the option of settling this  obligation in cash,  common
stock,  or a  combination  of both.  From time to time,  Corning may  repurchase
certain  additional  debt  securities  in open  market or  privately  negotiated
transactions.

The increase in working  capital,  excluding  cash and  short-term  investments,
reflects lower  short-term  borrowings and accounts  payable and higher deferred
taxes compared to December 31, 2001. The decrease in working capital,  excluding
cash and short-term  investments,  compared to September 30, 2001, was primarily
due to large  decreases  in  trade  accounts  receivable  and  inventories.  The
increase in days sales outstanding, compared to December 31, 2001, resulted from
lower December sales due to the scheduled  facility  shutdowns at year-end.  The
large  decrease  in trade  accounts  receivable  and  inventories,  compared  to
September 30, 2001,  was due to the  significant  decline in revenues and demand
for telecommunication products.






Financing Matters and Credit Ratings

Corning had no commercial paper borrowings as of September 30, 2002, nor does it
anticipate  issuing  commercial  paper  for  the  foreseeable  future.   Corning
maintains a $2.0 billion  revolving  credit facility with 18 banks,  expiring on
August 17, 2005.  As of September 30, 2002,  there were no borrowings  under the
credit facility.  The facility includes a covenant requiring Corning to maintain
a total debt to capital  ratio,  as defined,  not greater than 60%. At September
30,  2002,  and  December  31,  2001,  this ratio was 44% and 47%,  respectively
compared with 41% at September  30, 2001.  The decrease in total debt to capital
from  December 31,  2001,  to  September  30,  2002,  was due to the issuance of
mandatory  convertible preferred stock and open market purchases of a portion of
the zero coupon  convertible  debentures and repayment of commercial  paper. The
ratio  increase from  September 2001 to September 2002 was due to the net losses
incurred in 2002 and the  issuance of  convertible  debt in  November  2001.  As
disclosed in Goodwill and Other Intangible Assets, further declines in Corning's
Telecommunications Segment could cause future impairments of goodwill,  tangible
or  intangible  assets or  restructuring  charges.  These  items  could  cause a
material increase to Corning's debt to capital ratio.  Management believes there
are a  range  of  possible  outcomes  and no  assurance  can be  given  that  an
impairment  charge will not be required.  As of September 30, 2002,  Corning had
not provided vendor financing to any of its customers.

Corning's credit ratings as of October 30, 2002, were as follows:

RATING AGENCY                      Rating                        Rating
Last Update                    Long-Term Debt               Commercial Paper

    July 24, 2002

Note:  All three rating agencies maintain a Negative Outlook.

In July 2002, all three rating agencies announced a downgrade which is reflected
in the  ratings  above.  Although  the  sub-investment  grade  ratings  preclude
Corning's access to the commercial  paper market,  Corning's  overall  financial
flexibility  continues  to  be  adequate  as a  result  of  its  cash  position,
short-term investment holdings and committed revolving credit facilities.

An additional  downgrade  could further impact  Corning's  ability to enter into
foreign  exchange hedge  contracts with a duration of greater than a year.  Such
limitation would not significantly impact the company's current hedging program.
In  addition,  the  sub-investment  grade  credit  rating has in some  instances
resulted in requirements to deposit cash with  counterparties  under performance
surety bond and letter of credit arrangements.

Obligations, Commitments and Contingencies

Corning's  cash  obligations,  commercial  commitments  and  contingencies  were
relatively  the same as those  disclosed in Corning's Form 10-K/A filed March 7,
2002,  except  for  a  decrease  of  approximately  $75  million,  primarily  in
contingencies  related to  acquisitions  and performance  bonds.  See Note 11 to
Consolidated  Financial  Statements  for  an  updated  discussion  of  Corning's
litigation exposure associated with Pittsburgh Corning Corporation.

In-Process Research and Development

Corning  completed  a  number  of  purchase  acquisitions  in  2000.  As part of
analyzing each of these acquisitions,  Corning made a decision to buy technology
that  had not  yet  been  commercialized  rather  than  develop  the  technology
internally.  Corning based this  decision on a number of factors,  including the
amount of time it would take to bring the  technology  to market.  Corning  also
considered  its  internal  research  resource  allocation  and its  progress  on
comparable technology,  if any. Corning expects to use the same decision process
in the future.






NZ Applied Technologies
-----------------------

On May 5, 2000,  Corning  completed the  acquisition of NZ Applied  Technologies
(NZAT).  NZAT was  developing a line of high speed,  solid-state  components for
dense  wavelength  division  multiplexing  systems,  such  as  variable  optical
attenuators,  that will meet  industry  demands for speed and quality.  Of these
projects,  four were  determined to meet the criteria for  purchased  in-process
research and development (IPRD) as of the acquisition date.  Projected debt-free
income  was   initially   discounted   using  a  rate  of  21%  to  reflect  the
weighted-average  cost of capital  (entity risk) for NZAT. Each product was also
discounted  to account for the  research  project's  stage of  development.  The
completion  percentages  ranged  from  10%-80%.  At the  acquisition  date,  the
projected costs to complete the IPRD programs  approximated  $10 million.  A $44
million  non-tax  deductible  IPRD  charge  was  recognized  and  the  value  of
individual projects ranged from $1 million to $29 million.

In  the  third  quarter,   due  to  the  significant   downturn  in  demand  for
telecommunication's products, Corning decided to suspend the research related to
these  projects.  When  the  demand  for  Corning's  telecommunication  products
rebounds, management will reevaluate the market at that time and a decision will
be made as to whether research and development on these projects should resume.

Critical Accounting Policies

The preparation of financial  statements  requires  management to make estimates
and assumptions  that affect amounts  reported  therein.  Corning  described the
items that require management's most difficult,  subjective or complex judgments
in its Form 10-K/A filed March 7, 2002. This disclosure continues to be relevant
to the current year.

The  current  economic  depression  in  the   telecommunications   industry  has
introduced  additional  uncertainty and makes judgments in 2002 about allowances
for bad debts and inventory  realization more complex.  The  creditworthiness of
customers  requires reliance on information  provided by analysts if the company
is  public  and  judgments  about  the  liquidity  of other  companies  based on
incomplete  information.  Inventory  realization  requires  estimates  of market
demand for product on hand and forecasting of future technological developments.
Inventory  reserves are the most judgmental in the photonics  business where the
items are highly  technical and built to customer  specifications.  At September
30,  2002,  the  inventory   carrying  value   associated   with  this  business
approximated $38 million.

The telecommunication industry downturn is also adversely impacting many private
companies in which Corning made  investments  at high  valuations  accounted for
under the cost  method.  In the second  quarter of 2002,  Corning  wrote off its
balance in a number of such investments  despite the continued  operation of the
entities.  Certain  events  such  as  completed,  planned  or  failed  financing
activities  at each  company  make it likely that  Corning  will not realize any
proceeds from its investment.

New Accounting Standards

In June 2001,  the FASB issued SFAS No. 143,  "Accounting  for Asset  Retirement
Obligations."  This standard  addresses  financial  accounting and reporting for
obligations associated with the retirement of tangible long-lived assets and the
associated asset retirement costs. Corning is required to implement SFAS No. 143
on January 1, 2003.  Corning  does not expect  this  standard to have a material
impact on its consolidated financial position or results of operations.

In June 2002,  the FASB issued SFAS No. 146,  "Accounting  for Costs  Associated
with Exit or Disposal  Activities." This standard nullifies Emerging Issues Task
Force Issue No. 94-3,  "Liability  Recognition for Certain Employee  Termination
Benefits and Other Costs to Exit an Activity  (including  Certain Costs Incurred
in a  Restructuring)."  This  standard  requires  that  a  liability  for a cost
associated with an exit or disposal activity be recognized when the liability is
incurred rather than the date of an entity's commitment to an exit plan. Corning
is required to  implement  SFAS No. 146 on January 1, 2003.  Corning has not yet
determined the impact,  if any, that this standard will have on its consolidated
financial position or results of operations.






Forward-Looking Statements

The  statements in this Quarterly  Report on Form 10-Q, in reports  subsequently
filed by Corning  with the SEC on Form 8-K and related  comments  by  management
which  are not  historical  facts  or  information  and  contain  words  such as
"believes,"  "expects,"  "anticipates,"  "estimates,"  "forecasts,"  and similar
expressions are forward-looking  statements.  These  forward-looking  statements
involve  risks  and  uncertainties  that may  cause  the  actual  outcome  to be
materially different.  Such risks and uncertainties include, but are not limited
to:

-    global economic conditions,
-    currency fluctuations,
-    product demand and industry capacity,
-    competitive products and pricing,
-    sufficiency of manufacturing capacity and efficiencies,
-    cost reductions,
-    availability and costs of critical materials,
-    new product development and commercialization,
-    attracting and retaining key personnel,
-    order activity and demand from major customers,
-    fluctuations  in capital  spending by customers  in the  telecommunications
     industry and other business segments,
-    financial condition of customers
-    changes in the mix of sales between premium and non-premium products,
-    facility expansions and new plant start-up costs,
-    adverse litigation or regulatory developments,  including future or pending
     tax legislation,
-    adequacy and availability of insurance per Series C Prospectus
-    capital resource and cash flow activities,
-    capital spending,
-    equity company activities,
-    interest costs,
-    acquisition and divestiture activity,
-    the rate of technology change,
-    the ability to enforce patents,
-    product performance issues,
-    stock price fluctuations, and
-    other risks detailed in Corning's SEC filings.






Risk Factors

Set forth below and elsewhere in this Quarterly  Report,  and in other documents
we file with the SEC, are some of the  principal  risks and  uncertainties  that
could  cause  our  actual  business  results  to  differ   materially  from  any
forward-looking  statements  or other  projections  contained in this  Quarterly
Report.  In addition,  future  results could be  materially  affected by general
industry and market conditions, general U.S. and non-U.S. economic and political
conditions,  including a global economic slowdown, fluctuation of interest rates
or currency  exchange  rates,  terrorism  or  international  conflicts,  natural
disasters or other disruptions of expected economic conditions.

Our  sales  could be  negatively  impacted  if one or more of our key  customers
substantially reduce orders for our products

     Our customer base is relatively  concentrated with less than 10 significant
customers  accounting for a high  percentage  (greater than 50%) of net sales in
most of our businesses.  However,  no individual customer accounts for more than
10% of consolidated sales.

     Over recent periods, most of our major customers in the  Telecommunications
Segment  have  reduced  their  purchases  of our  products  and  have  expressed
uncertainty  as to their  future  requirements.  As a  result,  our  sales  have
declined and it is difficult to predict future sales accurately.  The conditions
contributing to this difficulty include:

     .    the prolonged downturn in the telecommunications industry;
     .    uncertainty   regarding  the  capital  spending  plans  of  the  major
          telecommunications  carriers, upon which our customers and, ultimately
          we, depend for sales;
     .    the telecommunications carriers' current limited access to the capital
          required for expansion; and
     .    general market and economic uncertainty.

     While we have responded to the depressed market by reducing excess capacity
and cutting  costs,  we cannot  assure you that our plans will be  successful in
mitigating the adverse effects of a prolonged downturn.  The current downturn in
the telecommunications  industry may be more severe and prolonged than expected.
If our net sales continue to decline, our ability to meet financial expectations
for future periods may be impaired.

If we do not  successfully  adjust  our  manufacturing  volumes  and fixed  cost
structure,  or achieve  manufacturing  yields or sufficient product reliability,
our operating results could suffer

     In the current  economic and industry  downturn,  we have  responded to the
softer market by cutting  costs,  including  the reduction of our  manufacturing
volumes. In 2001, we closed seven major  manufacturing  facilities and downsized
our workforce by approximately  12,000  positions.  We have continued to execute
our  restructuring  plans in 2002 and expect to close two fiber  facilities  and
mothball  another and to close several smaller  photonics,  cabling and hardware
and equipment locations. We have announced plans in 2002 to reduce our workforce
by  approximately  6,800 positions by early 2003. We may not be able to complete
our planned restructuring and facility consolidation  activities as expected or,
even  if we do so,  we may  not  achieve  all of the  cost  reductions  that  we
anticipate. We cannot assure you that our plans will be successful in mitigating
the adverse  effects of a softer market,  nor can we assure you that  additional
adjustments will not be necessary to respond to further market changes.

     The  manufacturing  of our  products  involves  highly  complex and precise
processes, requiring production in highly controlled and clean environments. Any
changes  in  our  manufacturing  processes  or  those  of  our  suppliers  could
significantly reduce our manufacturing  yields and product reliability.  In some
cases, existing  manufacturing may be insufficient to achieve the volume or cost
targets of our customers.  We will need to develop new  manufacturing  processes
and techniques to achieve targeted volume and cost levels.  While we continue to
fund projects to improve our manufacturing  techniques and processes, we may not
achieve cost levels in our manufacturing  activities that will fully satisfy our
customers.






We have incurred, and may in the future incur, restructuring,  inventory-related
and other charges, the amounts of which are difficult to predict accurately

     The  negative  trends,   primarily  in  the  telecommunications   industry,
beginning in 2001 such as excess manufacturing capacity,  increased intensity of
competition  and growing  pressure in price and profits have continued to hamper
the industry in 2002.  In the nine months  ended  September  30,  2002,  we have
recorded  charges  totaling $619 million  ($413  million  after-tax and minority
interest).  The charges included $257 million for  restructuring  charges,  $286
million for  impairment  of assets,  $60 million for the write-off of cost based
investments and $16 million for the loss on disposal of a business.

     We also anticipate an additional pre-tax restructuring charge in the fourth
quarter of 2002 in the range of $550  million  to $650  million.  Management  is
still considering  additional  actions that may be announced later in the fourth
quarter.  It is possible that additional  impairments and restructuring  charges
will result from these  actions or decreases in expected  cash flows from assets
not abandoned.

     Our  ability to  forecast  our  customers'  needs for our  products  in the
current economic and industry  environment is very limited.  Our results in 2001
included  significant  charges  for  inventory  write-downs,  primarily  in  the
photonic technologies  business.  Write-downs in this business have continued in
2002.

     Corning  may  record  additional  charges  for   restructuring,   inventory
adjustments,  or other  asset  impairments  if the  downturn  is more  severe or
prolonged than we currently anticipate.

If the  markets for our  products  do not  develop and expand as we  anticipate,
demand for our products may decline further,  which would negatively  impact our
results of operations and financial performance

     The  markets  for  our  products  are  characterized  by  rapidly  changing
technologies,   evolving   industry   standards   and   frequent   new   product
introductions.  Our success is expected to depend,  in substantial  part, on the
timely and successful introduction of new products, upgrades of current products
to comply with emerging industry standards,  our ability to acquire technologies
needed to remain  competitive and our ability to address competing  technologies
and products. In addition, the following factors related to our products and the
markets for them, if not achieved,  could have an adverse  impact on our results
of operations and financial performance:

     .    our ability to introduce leading products such as optical fiber, glass
          for flat panel displays, and environmental substrate products that can
          command competitive prices in the marketplace;
     .    our ability to maintain  or achieve a favorable  mix of sales  between
          premium and non-premium products;
     .    our ability to  continue  to develop new product  lines to address our
          customers'  diverse needs within the several market  segments in which
          we participate.  This requires a high level of innovation,  as well as
          the accurate anticipation of technological and market trends; or
     .    our  ability  to  create  the   infrastructure   required  to  support
          anticipated growth in certain businesses.

Corning's  reduced  investment in research,  development and  engineering  could
limit our ability to develop new products for the future.

We face pricing pressures in each of our leading businesses that could adversely
affect our results of operations and financial performance

     We periodically face pricing pressures in each of our leading businesses as
a result of intense  competition,  emerging new technologies,  and manufacturing
efficiencies in both the domestic and the international  marketplaces.  While we
will work toward reducing our costs to respond to the pricing pressures that may
continue, we may not be able to achieve proportionate  reductions in costs. As a
result of  overcapacity  and the current  economic and industry  downturn in the
Telecommunications  Segment,  pricing  pressures may increase in the foreseeable
future,  particularly  in our  optical  fiber  and  cable  business,  which  has
experienced price declines of 10% to 15% in the third quarter of 2002.






We have  incurred,  and may in the future incur,  goodwill and other  intangible
asset impairment charges

     Acquisitions  recorded as purchases for accounting  purposes have resulted,
and in the future may  result,  in the  recognition  of  significant  amounts of
goodwill and other  purchased  intangibles.  The  potential  impairment of these
assets could reduce our net income and shareholders' equity.

     In June 2001, the Financial  Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 142 pursuant to which goodwill will no
longer be amortized,  but will be subject to impairment tests at least annually.
SFAS No. 142 was effective for us on January 1, 2002.

     We completed our initial impairment review during the first quarter of 2002
and  concluded  that a  transitional  impairment  charge  from  adoption  of the
standard was not  required.  Corning has selected the fourth  quarter to conduct
annual  impairment  tests.  The  outcome  of the  impairment  test is  primarily
dependent upon the fair value of the reporting units. Business conditions in the
telecommunications  industry have deteriorated during the year and are depressed
such that it appears the fair value of  Corning's  telecommunications  reporting
unit is currently  lower than at the benchmark  assessment date of January 2002.
As part of the annual  impairment test,  management is currently  studying short
and long-term market  indicators and alternative  growth patterns.  Based on the
work performed to date, it appears reasonably  possible that a portion,  but not
all  of the  company's  goodwill  is  impaired.  Management  will  complete  the
impairment  test  in  the  fourth  quarter  and  record  any  required  goodwill
impairment  charge.  The goodwill related to the  Telecommunications  Segment is
$1.9 billion at September  30, 2002.  Management  believes  there are a range of
possible  outcomes and no assurance can be given that an impairment  charge will
not be  required.  A charge  would lower the  company's  equity and could reduce
availability under the unused $2.0 billion revolving credit facility.

We may be limited in our ability to obtain  additional  capital on  commercially
reasonable terms

     Although we believe  existing cash,  short-term  investments  and borrowing
capacity,  collectively,  provide adequate  resources to fund ongoing  operating
requirements,  we may be  required  to  seek  additional  financing  to  compete
effectively in our markets.  Our public debt ratings affect our ability to raise
capital and the cost of such capital.  In July 2002, Fitch downgraded our senior
unsecured long-term debt rating from BBB- to BB. In July 2002, Standard & Poor's
downgraded  our senior  unsecured  long-term  debt  rating  from BBB- to BB+ and
short-term debt credit rating from A-3 to B. Also, in July 2002, Moody's reduced
our senior unsecured  long-term debt rating from Baa3 to Ba2 and short-term debt
credit  rating  from  Prime-3 to Not  Prime.  All of the  rating  agencies  have
maintained negative outlooks.  These and any further downgrades may increase our
cost of  capital  borrowing  costs and  affect  our  ability  to access the debt
capital markets on a consistent  basis.  In addition,  the pricing of our common
stock may limit our ability to access the equity capital markets on terms and in
amounts that would be satisfactory to us.
     We may  experience  difficulties  as a result  of our  lower  debt  ratings
including but not limited to the  following:
     .    Customers  may seek  alternative  suppliers  if they become  concerned
          about Corning's financial condition.
     .    We may  face  increasing  requirements  to post  cash  collateral  for
          performance bonds.
     .    Counter  parties  may not want to accept the risk in foreign  exchange
          hedging transactions with Corning.

     We are subject  under our  revolving  credit  facility  to a covenant  that
requires us to maintain a ratio of total debt to capital,  as defined  under the
credit  facility,  of not greater  than 0.60 to 1.00.  Our total debt to capital
ratio was 0.44 at September  30, 2002.  This covenant may also limit our ability
to borrow additional funds. Further declines in our  Telecommunications  Segment
could  cause   impairments  of  goodwill,   tangible  or  intangible  assets  or
restructuring charges related to our overall business. These items could cause a
material increase in our total debt to capital ratio.






If  our  products  or  components   purchased  from  our  suppliers   experience
performance issues, our business will suffer

     Our business  depends on our producing  excellent  products of consistently
high quality. To this end, our products, including components purchased from our
suppliers,  are  rigorously  tested for  quality  both by us and our  customers.
Nevertheless,  our  products  are  highly  complex  and our  customers'  testing
procedures are limited to evaluating  our products under likely and  foreseeable
failure scenarios. For various reasons (including,  among others, the occurrence
of performance problems  unforeseeable in testing),  our products and components
purchased from our suppliers may fail to perform as expected. Performance issues
could  result  from  faulty  design  or  problems  in  manufacturing.   We  have
experienced  such  performance  issues in the past and  remain  exposed  to such
performance  issues.  In some cases,  product  redesigns or  additional  capital
equipment may be required to correct a defect.  In addition,  any significant or
systemic  product  failure  could  result in lost future  sales of the  affected
product and other products, as well as result in customer relations problems.

Interruptions  of  supplies  from our key  suppliers  may affect our  results of
operations and financial performance

     Interruptions  of supplies from our key suppliers could disrupt  production
or impact our ability to increase production and sales. We do not have long-term
or volume purchase agreements with every supplier,  and may have limited options
for alternative supply if these suppliers fail, for any reason,  including their
business  failure  or  financial   difficulties,   to  continue  the  supply  of
components.

We face intense competition in most of our businesses

     We  expect  that  we  will  face  additional   competition   from  existing
competitors  and from a number of companies that may enter our markets.  Because
some of the markets in which we compete have been historically  characterized by
rapid growth and are  characterized by rapid technology  changes,  smaller niche
and start-up  companies may become our principal  competitors in the future.  We
must invest in research and development,  expand our engineering,  manufacturing
and marketing capabilities, and continue to improve customer service and support
in order to remain competitive.  While we expect to undertake the investment and
effort in each of these areas, we are reducing our expenditure levels and cannot
assure you that we will be able to maintain or improve our competitive position.
In particular,  the net losses in our  Telecommunications  Segment may constrain
our  ability  to  invest  as much as we would  like in each of these  areas.  In
addition,  while some of our competitors are similarly  experiencing the effects
of  this  market  turmoil,   they  may  have  greater  financial,   engineering,
manufacturing, marketing or other support resources.

We may experience difficulties in enforcing our intellectual property rights and
we may be subject to claims of infringement of the intellectual  property rights
of others

     We may encounter  difficulties  in  protecting  our  intellectual  property
rights or obtaining  rights to  additional  intellectual  property  necessary to
permit us to continue or expand our  businesses.  We cannot  assure you that the
patents that we hold or may obtain will provide  meaningful  protection  against
our  competitors  or  competitive  technologies.  Litigation may be necessary to
enforce our intellectual  property  rights,  to protect our trade secrets and to
determine  the  validity  and scope of our  proprietary  rights.  Litigation  is
inherently  uncertain and the outcome is often  unpredictable.  Other  companies
hold patents on technologies used in our industries and are aggressively seeking
to expand, enforce and license their patent portfolios.
     The  intellectual  property  rights of others could  inhibit our ability to
introduce new products.  We are, and may in the future be,  subject to claims of
intellectual  property infringement or misappropriation and we cannot assure you
as to the outcome of such claims. Litigation or claims against us could force us
to cease selling or using any of our products that  incorporate the intellectual
property  that is the  subject  of such  claims,  obtain a license  from a third
party,  or redesign or rename our products.  These actions,  if possible,  could
result in substantial costs or loss of revenue.






Current or future  litigation  may harm our  financial  condition  or results of
operations

     Pending,   threatened   or  future   litigation   is  subject  to  inherent
uncertainties. Our financial condition or results of operations may be adversely
affected by unfavorable outcomes, expenses and costs exceeding amounts estimated
or  insured.  In  particular,  we have been  named as a  defendant  in  numerous
lawsuits  against  Pittsburgh  Corning  Corporation and several other defendants
involving  claims  alleging  personal  injury  from  exposure  to  asbestos.  As
described  in Legal  Proceedings  in our reports  filed with the SEC, our recent
negotiations  with the  representatives  of  asbestos  claimants  have failed to
produce a settlement to date and it currently  appears more likely than not that
we will litigate these cases. Alternatively, in the event that we reach a global
settlement through the Pittsburgh Corning Corporation  bankruptcy  process,  the
outcome may be material  to the  results of  operations  for the period in which
such costs, if any, are recognized. Management expects that any after-tax charge
resulting from Corning's  contributions  as part of a possible  settlement could
approximate  $100  million to $150  million  and will  depend upon the timing of
contributions  and  relative  participation  of insurance  carriers.  Management
cannot provide  assurances  that the ultimate  outcome of a settlement  would be
within this range.

We face risks related to our international operations and sales

     We have customers located outside the United States, as well as significant
non-United States operations,  including manufacturing and sales. As a result of
these international operations, we face a number of risks, including:

     .    difficulty of effectively managing our diverse global operations;
     .    change in regulatory requirements;
     .    tariffs and other trade barriers;
     .    political and economic instability in foreign markets; and
     .    fluctuations  in foreign  currencies  which may make our products less
          competitive  in countries in which local  currencies  decline in value
          relative to the dollar.

If we fail to retain and attract key  personnel,  our results of operations  and
financial performance may suffer

     Our future  success will be determined in part by our ability to retain and
attract key scientific and technical personnel for our research, development and
engineering efforts. Our business also depends on the continued contributions of
our  executive  officers  and  other  key  management.  We may also find it more
difficult to retain or attract qualified  employees due to our uncertain outlook
and  reductions   affecting   compensation,   benefits,   and  employee   equity
participation  programs.  While  we  believe  that we have  been  successful  in
retaining  and  attracting  key  personnel,  we cannot  assure  you that we will
continue to be successful in the future.

If the  financial  condition of our customers  declines,  our credit risks could
increase

     Recently,  certain of our  customers  have  filed  with the courts  seeking
protection under the applicable  bankruptcy or reorganization  laws or have been
experiencing financial difficulties.  We have experienced, and in the future may
experience,  losses  as a  result  of our  inability  to  collect  our  accounts
receivable,  as well as the loss of such  customer's  ongoing  business.  If our
customers  fail to meet their  payment  obligations  to us, we could  experience
reduced cash flows and losses in excess of amounts reserved. As of September 30,
2002, reserves for trade receivables totaled approximately $48 million.

We may not have adequate insurance coverage for claims against us

     We face the risk of loss resulting from, and adverse  publicity  associated
with, product liability, securities, fiduciary liability, intellectual property,
contractual,  warranty, fraud and other lawsuits, whether or not such claims are
valid. In addition,  our product liability,  fiduciary,  directors and officers,
property and comprehensive  general  liability  insurance may not be adequate to
cover such claims,  insurance costs may increase substantially and we may not be
able to get adequate  insurance  coverage in the future at acceptable  costs.  A
successful  claim that  exceeds or is not  covered  by our policy  limits  could
require us to pay  substantial  sums. In addition,  we may not be able to insure
against  certain  risks or obtain  some types of  insurance,  such as  terrorism
insurance.






ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk Disclosures

There have been no material  changes to  Corning's  market risk  exposure  since
December 31, 2001, except for the following change described below.

Interest Rate Risk Management

In March and April of 2002,  Corning  entered into  interest rate swaps that are
fair  value  hedges  and  economically  exchanged  $275  million  of fixed  rate
long-term  debt to floating rate debt.  Under the terms of the swap  agreements,
Corning  will pay the  counterparty  a  floating  rate  that is  indexed  to the
six-month  LIBOR rate and receive  the fixed rates of 8.3% to 8.875%,  which are
the stated  interest  rates on the long-term  debt  instruments.  As a result of
these  transactions,  Corning is exposed to the impact of interest rate changes.
The interest rate on these instruments is reset every six months and they expire
in 14 to 23 years. It is Corning's policy to conservatively  manage its exposure
to changes in  interest  rates.  Corning's  policy is that  total  floating  and
variable  rate debt will not exceed 35% of the total debt  portfolio at anytime.
At  September  30,  2002,   Corning's   consolidated  debt  portfolio  contained
approximately 8% of variable rate instruments.






ITEM 4.  CONTROLS AND PROCEDURES


(a)  Evaluation of Disclosure Controls and Procedures

     Corning's  Chief  Executive   Officer  and  Chief  Financial  Officer  have
     evaluated the company's  disclosure  controls and  procedures as of October
     29,  2002,  and they  concluded  that these  controls  and  procedures  are
     effective.

(b)  Changes in Internal Controls

     There are no significant  changes in internal  controls or in other factors
     that could  significantly  affect these controls  subsequent to October 29,
     2002.








                           Part II - Other Information
                           ---------------------------

ITEM 1.  LEGAL PROCEEDINGS

Environmental Litigation. Corning has been named by the Environmental Protection
Agency under the  Superfund  Act, or by state  governments  under  similar state
laws, as a potentially  responsible  party at 12 active  hazardous  waste sites.
Under the  Superfund  Act, all parties who may have  contributed  any waste to a
hazardous  waste site,  identified  by such  Agency,  are jointly and  severally
liable  for the cost of  cleanup  unless  the  Agency  agrees  otherwise.  It is
Corning's  policy to accrue for its  estimated  liability  related to  Superfund
sites and other  environmental  liabilities related to property owned by Corning
based on expert analysis and continual  monitoring by both internal and external
consultants.  Corning has accrued  approximately  $23 million for its  estimated
liability for environmental  cleanup and litigation at September 30, 2002. Based
upon the  information  developed to date,  management  believes that the accrued
reserve is a reasonable  estimate of the Company's  estimated liability and that
the risk of an additional loss in an amount  materially higher than that accrued
is remote.

Schwinger Toxins Lawsuit. In April 2002, Corning was served with a complaint for
plaintiffs  past and  current  injuries  allegedly  arising  from the release of
hazardous and toxic  substances  from a Sylvania  nuclear  materials  processing
facility near Hicksville, New York. An amended complaint was served in September
2002,  naming 205  plaintiffs and seeking  damages in excess of $3 billion.  The
complaint  names more than 20 other  corporate  defendants and is pending in the
United States  District Court for the Eastern  District of New York.  Plaintiffs
claim to have sustained  numerous types of cancer and other medical  conditions;
some plaintiffs  seek recovery for alleged  injuries to their decedents who died
as many as 20 years ago. A status  conference  originally  set for September 17,
2002, was reset for October 31, 2002. It is anticipated that the filing date for
defendants'  motion  to  dismiss  will be  December  2,  2002.  Based  upon  the
information  developed to date and recognizing that the outcome of litigation is
uncertain,  management believes that the risk of a materially adverse verdict is
remote.

Stevens  Toxins  Lawsuit.  In  April  2002,  Stevens,   and  eight  other  named
plaintiffs, initiated a proposed class action, in the Supreme Court of the State
of New York against many of the same defendants  named in the Schwinger  action.
At that time Corning was not named as a  defendant.  That action was amended and
filed in  September  2002 to include  Corning as a defendant  and removed to the
United States  District Court for the Eastern  District of New York.  Based upon
the information developed to date and recognizing that the outcome of litigation
is uncertain,  management believes that the risk of a materially adverse verdict
is remote.

Dow Corning Bankruptcy. Corning and The Dow Chemical Company each own 50% of the
common stock of Dow Corning  Corporation.  On May 15, 1995,  Dow Corning  sought
protection  under the  reorganization  provisions  of  Chapter  11 of the United
States  Bankruptcy  Code and  thereby  obtained a stay of  approximately  19,000
breast-implant  product liability lawsuits. On November 8, 1998, Dow Corning and
the Tort  Claimants  Committee  jointly  filed a revised Plan of  Reorganization
(Joint Plan) which was confirmed by the  Bankruptcy  Court on November 30, 1999.
On December 21, 1999, the  Bankruptcy  Court issued an opinion that approved the
principal  elements  of the  Joint  Plan with  respect  to tort  claimants,  but
construed  the Joint Plan as  providing  releases for third  parties  (including
Corning and Dow Chemical as  shareholders)  only with respect to tort  claimants
who voted in favor of the Joint Plan. On November 13, 2000,  the District  Court
entered an Order reversing the Bankruptcy  Court's December 21, 1999, Opinion on
the release and  injunction  provisions and confirmed the Joint Plan. On January
29,  2002,  the  U.S.  Court of  Appeals  for the  Sixth  Circuit  affirmed  the
determinations made in the District Court with respect to the foreign claimants,
but  remanded to the  District  Court for further  proceedings  with  respect to
certain  lien claims of the U.S.  government  and with  respect to the  findings
supporting  the  non-debtor  releases  in favor of Dow  Corning's  shareholders,
foreign  subsidiaries  and insurers.  In the District Court, the Plan proponents
and  opponents  filed  briefs  on the open  issues,  which  include  the  issues
surrounding the non-debtor  releases,  and the District Court heard arguments on
the remanded issues on June 14, 2002. The District Court reserved  decision.  It
is probable  that any decision by the District  Court will be subject to further
appeals.  The Plan  proponents  agreed  to  settle  the lien  claims of the U.S.
government for $9.8 million to be paid from the Settlement  Fund under the Plan.
This settlement was approved by the District Court in the third quarter of 2002.
If the Joint Plan with  shareholder  releases is upheld after all  appeals,  any
remaining  personal  injury  claims  against  Corning in these  matters  will be
channeled to the  resolution  procedures  under the Plan. If the Joint Plan with
shareholder  releases is not upheld after all appeals,  Corning  would expect to
defend any remaining  claims against it (and any new claims) on the same grounds
that led to a series of orders  and  judgments  dismissing  all  claims  against
Corning in the federal  courts and in many state courts as  described  under the
heading Implant Tort Lawsuits  immediately  hereafter.  Management believes that
the claims  against  Corning lack merit and that the breast  implant  litigation
against Corning will be resolved without material impact on Corning's  financial
statements.

Under the terms of the Joint Plan,  Dow Corning would be required to establish a
Settlement Trust and a Litigation Facility to provide a means for tort claimants
to settle or litigate  their claims.  Dow Corning  would have the  obligation to
fund the Trust and the Facility,  over a period of up to 16 years,  in an amount
up to  approximately  $3.3  billion,  subject  to  the  limitations,  terms  and
conditions  stated in the Joint Plan.  Corning and Dow Chemical have each agreed
to provide a credit  facility to Dow Corning of up to $150 million ($300 million
in the aggregate), subject to the terms and conditions stated in the Joint Plan.
The Joint Plan also provides for Dow Corning to make full payment,  through cash
and issuance of senior notes, to its commercial creditors. These creditors claim
approximately  $810 million in  principal  plus an  additional  sum for pendency
interest,  costs and fees from the  petition  date (May 15,  1995)  through  the
effective  date under the Plan when payment is made.  The  commercial  creditors
have  contested  the  Bankruptcy  Court's   disallowance  of  their  claims  for
post-petition  interest at default  rates of interest,  and have appealed to the
District  Court.  The District  Court heard oral  argument this appeal on May 2,
2002,  and has not yet ruled.  The amount of  additional  interest cost and fees
claimed by the commercial  creditors is approximately  $100 million pre-tax more
than Dow  Corning  believes  it should  pay.  If and when it appears  likely Dow
Corning will emerge from  bankruptcy,  Corning expects to resume the recognition
of  equity  earnings  from Dow  Corning.  Corning  does not  expect  to  receive
dividends from Dow Corning in the foreseeable future.

Implant Tort Lawsuits. Corning and Dow Chemical, the shareholders of Dow Corning
Corporation,  were named in a number of state and federal tort lawsuits alleging
injuries  arising from Dow Corning's  implant  products.  The claims against the
shareholders  alleged a variety of direct or indirect theories of liability.  In
1992, the federal breast implants cases were  coordinated for pretrial  purposes
in the United States District Court,  Northern District of Alabama (Judge Sam C.
Pointer,  Jr.).  In April 1995,  the District  Court  granted  Corning a summary
judgment  dismissing it from over 4,000 federal court cases.  On March 12, 1996,
the U.S.  Court of Appeals for the Eleventh  Circuit  dismissed the  plaintiffs'
appeal  from that  judgment.  In state  court  litigation,  Corning  was awarded
summary  judgment  in  California,  Connecticut,  Illinois,  Indiana,  Michigan,
Mississippi,  New Jersey, New York, Pennsylvania,  Tennessee, and Dallas, Harris
and Travis  Counties  in Texas,  thereby  dismissing  approximately  7,000 state
cases. In Louisiana,  Corning's  summary judgment was vacated by an intermediate
appeals court in Louisiana as premature. The Louisiana cases were transferred to
the United States District Court for the Eastern District of Michigan,  Southern
Division  (Michigan  Federal  Court) to which  substantially  all breast implant
cases were transferred in 1997. In the Michigan Federal Court,  Corning is named
as a defendant in  approximately  70 pending  cases  (including  some cases with
multiple  claimants),  in  addition  to the  transferred  Louisiana  cases.  The
Michigan  Federal Court heard Corning's  motion for summary judgment on February
27, 1998, but has not ruled.  Based upon the  information  developed to date and
recognizing  that the outcome of complex  litigation  is  uncertain,  management
believes that the risk of a materially  adverse result in the implant litigation
against  Corning is remote and believes the implant  litigation  against Corning
will be resolved without material impact on Corning's financial statements.

Federal Securities Cases. A federal securities class action lawsuit was filed in
1992 against Corning and certain individual  defendants by a class of purchasers
of Corning stock who allege  misrepresentations  and omissions of material facts
relative to the silicone gel breast implant  business  conducted by Dow Corning.
This  action is pending in the United  States  District  Court for the  Southern
District of New York. The class consists of those purchasers of Corning stock in
the period from June 14, 1989, to January 13, 1992,  who allegedly  purchased at
inflated   prices  due  to  the   non-disclosure   or  concealment  of  material
information.  No amount of damages is specified in the  complaint.  In 1997, the
Court  dismissed the  individual  defendants  from the case.  In December  1998,
Corning filed a motion for summary  judgment  requesting that all claims against
it be dismissed. Plaintiffs requested the opportunity to take depositions before
responding  to the  motion  for  summary  judgment.  The  discovery  process  is
continuing  and the Court  has set no  schedule  to  address  the still  pending
summary  judgment  motion.  Corning  intends to  continue  to defend this action
vigorously.  Based upon the information  developed to date and recognizing  that
the outcome of litigation is uncertain,  management believes that the likelihood
of a materially adverse verdict is remote.

From  December  2001 through  April 2002,  Corning and three of its officers and
directors were named defendants and served in four lawsuits alleging  violations
of the U.S.  securities laws in connection with Corning's November 2000 offering
of $2.7 billion zero coupon  convertible  debentures,  due November 2015, and 30
million shares of common stock.  These lawsuits are pending in the United States
District  Court for the Western  District of New York. In addition,  the Company
and the same three  officers and directors were named and served in ten lawsuits
alleging selective  disclosures and non-disclosures  that allegedly inflated the
price of Corning's  Common Stock in the period from  September 2000 through June
2001. The plaintiffs in these actions seek to represent classes of purchasers of
Corning's stock in all or part of the period  indicated.  On August 2, 2002, the
District  Court entered an order  consolidating  these actions for all purposes,
designating lead plaintiffs and lead counsel,  and directing that a consolidated
complaint be served within sixty days. The deadline for serving the consolidated
complaint was later extended  through October 25, 2002. This order provides that
defendants shall have sixty days after service of the consolidated  complaint to
answer, move or respond. The order further sets a schedule for briefing a motion
to dismiss and  provides  that a motion to certify the action as a class  action
shall be filed after all motions to dismiss are  resolved.  Another  lawsuit has
been filed,  also in the Western District of New York, on behalf of participants
in the Company's Investment Plan for Salaried Employees,  purportedly as a class
action on behalf of participants in the Plan who purchased or held Corning stock
in a Plan  account.  The  defendants in that action  responded  with a motion to
dismiss the  lawsuit on a variety of  grounds.  The  plaintiffs  filed  opposing
papers on October 10, 2002.  After  defendants file reply papers, a hearing will
be scheduled for oral  argument on the motion.  Management is prepared to defend
these lawsuits  vigorously  and,  recognizing  that the outcome of litigation is
uncertain,  believes that these will be resolved,  net of applicable  insurance,
without material impact on Corning's financial statements.

Pittsburgh Corning Corporation.  Corning and PPG Industries, Inc. (PPG) each own
50% of the  capital  stock of  Pittsburgh  Corning  Corporation  (PCC).  PCC and
several other defendants, including PPG and Corning, have been named in numerous
lawsuits involving claims alleging personal injury from exposure to asbestos. On
April 16, 2000,  PCC filed for Chapter 11  reorganization  in the United  States
Bankruptcy Court for the Western District of Pennsylvania.  As of the bankruptcy
filing,  PCC had in  excess  of  140,000  open  claims  and now has in excess of
240,000 open claims.

In the  bankruptcy  court,  PCC in April 2000 obtained a preliminary  injunction
against the  prosecution of asbestos  actions  against its two  shareholders  to
afford  the  parties  a  period  of time  (the  Injunction  Period)  in which to
negotiate a plan of reorganization for PCC.

On May 14, 2002,  PPG announced  that it had agreed with several other  parties,
including certain of its insurance  carriers and  representatives of current and
future asbestos claimants,  on the terms of a settlement arrangement relating to
asbestos claims against PPG and PCC. This settlement  would be incorporated in a
plan of reorganization  for PCC, and would be subject to a favorable vote by 75%
of the asbestos claimants voting on the PCC reorganization plan, and approval by
the  Bankruptcy   Court.   According  to  its   announcement,   PPG  would  make
contributions to a trust under the reorganization plan consisting of:
..    cash payments by PPG's  participating  insurance  carriers of approximately
     $1.7 billion over a 21 year period;
..    the  assignment  of rights to  certain  proceeds  of  policies  by  certain
     insurance carriers not participating in the settlement;
..    PPG's shares in PCC and Pittsburgh Corning Europe, a Belgian corporation;
..    1,388,889 shares of PPG's common stock; and
..    cash payments  from PPG of  approximately  $998 million over 21 years.
PPG announced on July 18, 2002,  that it recorded a charge in its second quarter
results of $495 million after-tax related to this settlement.

The  Injunction  Period as to Corning was extended  through  September 30, 2002,
when it expired by its terms.  Under the terms of the Bankruptcy  Court's Order,
Corning  has 90 days from  September  30, 2002 to seek  removal and  transfer of
pending  cases in which it is named as a  defendant.  At the time PCC  filed for
bankruptcy  protection,  there were approximately  12,400 claims pending against
Corning  alleging  various  theories  of  liability  based on  exposure to PCC's
asbestos products. Although the outcome of litigation and the bankruptcy case is
uncertain,  management  believes that the separate  corporate status of PCC will
continue to be upheld and that Corning has strong  legal  defenses to any claims
of direct liability arising from PCC's asbestos products.

After PPG announced its settlement,  negotiations between representatives of the
asbestos  claimants and Corning became more intensive.  These  negotiations have
failed to produce a settlement,  but  discussions  continue  intermittently.  In
Corning's  negotiations with the asbestos  claimants,  the range of negotiations
has been framed by demands  translating into  approximately $400 million to $500
million in net present value  (inclusive of insurance),  which is  significantly
lower than that reflected in the PPG settlement.  These  negotiations  have been
difficult,  and no assurances  can be offered that a settlement can be concluded
within this range.

Based on negotiations to date, management believes that a settlement (if one can
be reached) would probably include some  combination of the following  elements:
cash  payments  by Corning  over time into a trust;  contribution  of  Corning's
shares in PCC and Pittsburgh  Corning  Europe and common shares of Corning;  and
insurance  through cash payments or  assignments  of certain rights to insurance
proceeds.  However,  the  structure  of a  settlement  has not been  agreed  and
management can not estimate the likelihood  that any settlement will emerge from
negotiations with the claimants or Corning's  insurers,  or the probability that
Corning will be able to secure a release  through  PCC's plan of  reorganization
upon terms and conditions satisfactory to Corning.

At this time,  it appears more likely than not that  Corning  will  litigate the
asbestos cases, but will continue to explore a settlement through the bankruptcy
process.  The exposure for this asbestos litigation (net of insurance) cannot be
estimated at this time due to the wide range of potential  outcomes.  Corning is
also currently named in approximately 11,400 other cases  (approximately  34,000
claims)  alleging  injuries  from  asbestos.  Those  cases have been  covered by
insurance  without  material impact to Corning to date.  Asbestos  litigation is
inherently difficult, and the outcome of litigation is uncertain.

As a result of PCC's bankruptcy filing,  Corning recorded an after-tax charge of
$36 million in the first quarter of 2000 to impair its entire  investment in PCC
and discontinued  recognition of equity earnings. At September 30, 2002, Corning
has not  recorded any  additional  charges  associated  with the outcome of this
litigation.  As noted above, management believes there are strong legal defenses
to the claims against Corning.  Management estimates that the insurance coverage
available to Corning related to these matters exceeds $600 million and depending
on the outcome of potential  coverage  issues may exceed $1 billion.  Management
estimates  that  the  low end of the  range  of loss  resulting  from  continued
litigation is not material.  Due to the inherent uncertainty of asbestos related
litigation,  management  is unable to estimate  the maximum  exposure  from this
litigation.

Alternatively,  in the event that  Corning  and its  insurers  agree to a global
settlement of the  PCC-related  cases through the PCC  bankruptcy  process,  the
outcome may be material  to the  results of  operations  for the period in which
such costs, if any, are recognized. Management expects that any after-tax charge
resulting from Corning's  contributions  as part of a possible  settlement could
approximate  $100  million to $150  million  and will  depend upon the timing of
contributions  and  relative  participation  of insurance  carriers.  Management
cannot provide  assurances  that the ultimate  outcome of a settlement  would be
within this range.

Under either  alternative,  management  believes  these matters will be resolved
without material impact to Corning's overall financial position or its liquidity

Astrium. In December of 2000, Astrium,  SAS and Astrium,  Ltd. filed a complaint
for negligence in the United States  District Court for the Central  District of
California against TRW, Inc., Pilkington Optronics Inc., Corning NetOptix, Inc.,
OFC Corporation  and Optical Filter  Corporation  claiming  damages in excess of
$150 million.  The complaint alleges that certain cover glasses for solar arrays
used to generate  electricity  from solar energy on satellites sold by Astrium's
corporate  successor  were  negligently  coated by NetOptix or its  subsidiaries
(prior to  Corning's  acquisition  of NetOptix) in such a way that the amount of
electricity  the satellite can produce and their  effective life were materially
reduced.  NetOptix  has denied  that the  coatings  produced  by NetOptix or its
subsidiaries  caused the damage alleged in the complaint,  or that it is legally
liable for any damages  which  Astrium may have  experienced.  Formal  discovery
through document  production and depositions has begun and will continue through
October 2002 for fact witnesses and January 2003 for experts. In April 2002, the
Court granted motions for summary  judgment by NetOptix and other  defendants to
dismiss  the  negligence  claims,  but  permitted  plaintiffs  to add  fraud and
negligent  misrepresentation  claims  against  all  defendants  and a breach  of
warranty claim against NetOptix and its subsidiaries.  In October 2002 the Court
again  granted  defendants'  motions  for summary  judgment  and  dismissed  the
negligent  misrepresentation  and breach of  warranty  claims.  The only  claims
remaining are claims by plaintiff for intentional  fraud against all defendants.
Based upon the current case  management  order,  a trial has been  scheduled for
April 15, 2003.  Based upon the  information  developed to date and  recognizing
that the outcome of litigation is uncertain,  management believes that there are
strong  defenses to these  claims and  believes  they will be  resolved  without
material impact on Corning's financial statements.

Optel Arbitration. On June 28, 2002, Madeco S.A. and Madeco Brasil Ltda. filed a
notice of  arbitration  and  statement of claim  against  Corning  International
Corporation  with the American  Arbitration  Association  in New York, New York,
alleging  "breaches of its  contractual  duties and  partnership  obligations to
Madeco."  Among  other  things,  Madeco  requested  "no less than $20 Million to
compensate  Madeco  for the  breach of its  rights  under the Put  Option,  plus
additional  damages caused by Corning's  failure to perform under the Investment
Agreement and related  contracts." The  arbitration  panel has been convened and
mediation  is a  possibility,  but not yet  scheduled.  It is  anticipated  that
arbitration  hearings will not commence  until the first quarter of 2003.  Based
upon the  information  developed  to date and  recognizing  that the  outcome of
arbitration  is  uncertain,  management  believes  that the risk of a materially
adverse verdict is remote.

Astarte/Tellium. In July of 2002, Corning filed a demand for binding arbitration
between  Corning and Astarte Fiber Networks Inc.;  Tellium,  Inc.; AFN, LLC; and
their related parties.  The arbitration  concerns a contract relating to certain
patents and patent applications  previously owned by Astarte and now held by AFN
and  Tellium,  Astarte's  successor.  Corning's  demand  includes  a  claim  for
approximately $38 million from those parties due to material  misrepresentations
and fraud, as well as a claim to have the contract cancelled for breach. AFN has
counterclaimed in the arbitration, asking the arbitrators to decide that Corning
remains obligated under the contract for future contingent payments to AFN of up
to $50 million. While the outcome of arbitration  proceedings concerning complex
contracts  involving  intellectual  property  matters  cannot be predicted  with
certainty,  based upon the information  discovered to date,  management believes
that Corning's  claims are well founded and that the dispute will be resolved in
Corning's  favor  without  material  negative  impact  on  Corning's   financial
statements.
